A Study Of Electrical Power Systems Environmental Sciences Essay

Electrical power systems include a generating system, a transmittal and distribution system and tonss. Transmission and distribution system is an of import connecting nexus between the majority power bring forthing Stationss and the burden lopes. The coevals workss are usually located in topographic point where the resources are available to bring forth power economically. The recent tendency in power system pattern is to turn up the coevals workss off from the to a great extent populated countries. The power is so transmitted to the burden by transmittal lines and distribution webs. Transmission is made of a high electromotive force web, by and large 110 – 765 kilovolt Ac. The higher the electromotive force degree of a transmittal line, the lower is the transmittal power loss. However, the electromotive force bounds for the transmittal line electromotive forces are set by insularity and protective devices. The standard transmittal line electromotive forces depend upon the state and they are: 765, 550, 500, 400, 345, 275, 230, 169, 145, 132, 110, 66, 33 kilovolt. The electromotive forces in the scope of 345 – 765 kilovolts are classified as excess high electromotive force ( EHV ) . The electromotive forces above 765 kilovolts are considered as extremist high electromotive forces ( UHV ) . Presently, the UHV systems, at 1000- , 1500- , 2250- kilovolt electromotive force degrees are in research phase. Point to indicate transmittal is, some clip, preferred by HVDC. The electromotive force degrees used for HVDC power transmittal are: 250 kilovolt, 400 kilovolt, 500 kilovolt and 550 kilovolt. Higher District of Columbia electromotive forces are being planned. National Grid Malaysia is the chief electricity transmittal web associating the electricity coevals, transmittal, distribution and ingestion in Malaysia. It is operated and owned by Tenaga Nasional Berhad ( TNB ) . The transmittal line electromotive forces for Malaysia are runing at 132kV, 275kV and 500kV. Other than grid system, Malaysia besides has a High Voltage Direct Current Transmission line where the 300 MW Thailand – Malaysia HVDC interconnectedness system consists of Khlong Ngae convertor station on the Thai boundary line and Gurun convertor station on the Malaysia boundary line. Both Stationss are linked by a 300 KV DC overhead transmittal line of 110 kilometer. EGAT ‘s Khlong Ngae convertor station is situated at Sadao territory in Southern Songkhla state, approximately 24 km.from Thai-Malaysia boundary line. TNB ‘s Gurun convertor station is located in Kedah, approximately 86 kilometers. from Malaysia ‘s northern boundary line. Malaysia will purchase electricity during the twenty-four hours clip for our commercial use which is Malaysia ‘s Peak use and Thailand will purchase during the eventide boulder clay tardily dark where their use is at the extremum. History of Use In the early yearss of commercial usage of electric power, transmittal of electric power at the same electromotive force as used by illuming and mechanical tonss restricted the distance between bring forthing works and consumers. Originally coevals was with direct current, which could non easy be increased in electromotive force for long-distance transmittal. Different categories of tonss, for illustration, illuming, fixed motors and grip ( railroad ) systems, required different electromotive forces and so used different generators and circuits. The alleged â€Å" cosmopolitan system † used transformers both to twosome generators to high-potential transmittal lines, and to link transmittal to local distribution circuits. By a suited pick of public-service corporation frequence, both illuming and motor tonss could be served. Rotary convertors and subsequently mercury-arc valves and other rectifier equipment allowed DC burden to be served by local transition where needed. Even bring forthing Stationss and tonss utilizing different frequences could besides be interconnected utilizing rotary convertors. By utilizing common bring forthing workss for every type of burden, of import economic systems of graduated table were achieved, lower overall capital investing was required, load factor on each works was increased leting for higher efficiency, leting for a lower cost of energy to the consumer and increased overall usage of electric power. By leting multiple bring forthing workss to be interconnected over a broad country, electricity production cost was reduced. The most efficient available workss could be used to provide the varying loads during the twenty-four hours. Reliability was improved and capital investing cost was reduced, since stand-by bring forthing capacity could be shared over many more clients and a wider geographic country. Remote and low-priced beginnings of energy, such as hydroelectric power or mine-mouth coal, could be exploited to take down energy production cost. The first transmittal of three-phase jumping current utilizing high electromotive force took topographic point in 1891 during the international electricity exhibition in Frankfurt. A 25 kilovolt transmittal line, about 175 kilometers long, connected Lauffen on the Neckar and Frankfurt. Voltages used for electric power transmittal increased throughout the twentieth century. By 1914 55 transmittal systems runing at more than 70,000 V were in service, the highest electromotive force so used was 150,000 Vs. The first three-phase jumping current power transmittal at 110 kilovolts took topographic point in 1912 between Lauchhammer and Riesa, Germany. On April 17, 1929 the first 220 kilovolt line in Germany was completed, running from Brauweiler near Cologne, over Kelsterbach near Frankfurt, Rheinau near Mannheim, Ludwigsburg-Hoheneck near Austria. The masts of this line were designed for eventual ascent to 380 kilovolt. However the first transmittal at 380 kilovolt in Germany was on October 5, 1957 between the substations in Rommerskirchen and Ludwigsburg-Hoheneck. In 1967 the first extra-high-voltage transmittal at 735 kilovolts took topographic point on a Hydro-Quebec transmittal line. In 1982 the first transmittal at 1200 kilovolt was in the Soviet Union. The rapid industrialisation in the twentieth century made electrical transmittal lines and grids a critical portion of the economic substructure in most industrialised states. Interconnection of local coevals workss and little distribution webs was greatly spurred by the demands of World War I, where big electrical generating workss were built by authoritiess to supply power to weaponries mills ; subsequently these workss were connected to provide civil burden through long-distance transmittal. Small municipal electrical public-service corporations did non needfully want to cut down the cost of each unit of electricity sold ; to some extent, particularly during the period 1880-1890, electrical lighting was considered a luxury merchandise and electric power was non substituted for steam power. Engineers such as Samuel Insull in the United States and Sebastian Z. De Ferranti in the United Kingdom were instrumental in get the better ofing proficient, economic, regulative and political troubles in development of long-distance electric power transmittal. By debut of electric power transmittal webs, in the metropolis of London the cost of a kilowatt hr was reduced to tierce in a ten-year period. In 1926 electrical webs in the United Kingdom began to be interconnected in the National Grid, ab initio runing at 132,000 Vs. Hazard Posed by High Voltage Power Lines Electrical jeopardies The hovering electric and magnetic Fieldss in electromagnetic radiation will bring on an electric current in any music director through which it passes. Strong radiation can bring on current capable of presenting an electric daze to individuals or animate beings. It can besides overload and destruct electrical equipment. 3.1.1 Electrocution Hazards Working Near Overhead Power Lines Most overhead power lines are n ot insulated.Activities conducted near overhead powerlines such as: threading communicating wiring ; raising antenna masts ; mounting in trees and onto edifices ; and utilizing portable metal ladder presents a existent danger Fire jeopardies Highly high power electromagnetic radiation can do electric currents strong plenty to make flickers when an induced electromotive force exceeds the breakdown electromotive force of the environing medium. These flickers can so light flammable stuffs or gases, perchance taking to an detonation. This can be a peculiar jeopardy in the locality of explosives or pyrotechnics, since an electrical overload might light them. This hazard is normally referred to as RadHaz or HERO ( Hazards of Electromagnetic Radiation to Ordnance ) . Biological jeopardies The best understood biological consequence of electromagnetic Fieldss is to do dielectric warming. For illustration, touching an aerial while a sender is in operation can do terrible Burnss. This warming consequence varies with the frequence of the electromagnetic energy. The eyes are peculiarly vulnerable to RF energy in the microwave scope, and prolonged exposure to microwaves can take to cataracts. Each frequence in the electromagnetic spectrum is absorbed by populating tissue at a different rate, called the specific soaking up rate or SAR, which has units of Watts per kg ( W/kg ) . The IEEE and many national authoritiess have established safety bounds for exposure to assorted frequences of electromagnetic energy based on SAR. There are publications which support the being of complex biological effects of weaker non-thermal electromagnetic Fieldss, including weak ELF magnetic Fieldss and modulated RF and micro-cook Fieldss. Cardinal mechanisms of the interaction between biological stuff and electromagnetic Fieldss at non-thermal degrees are non to the full understood.. Environmental effects from transmittal lines can be found merely near to the line. Biological effects from electrical and magnetic Fieldss around the line have been intensively discussed during the last twosome of old ages. 3.4 Health Effectss Certain research surveies show fringy inauspicious wellness effects on human existences. Other surveies do non corroborate these effects. 3.5 Pollutant aerosols under high Voltage Power Lines A probe of theoretically and by experimentation conducted at H.H Wills Physics Laboratory University of Bristol to measure the increased exposure to airborne pollutants near power lines. Harmonizing to Fews ( 1999 ) , exposures were carried out at different power line location in assorted conditions conditions and the exposure are taken along a line at a right angles up to 200m from a figure of high electromotive force power transmittal line. The consequence of the theoretical account predicts a two of three fold addition in deposition of aerosols on spherical surfaces miming the human caput under high electromotive force lines. This status applies when pesticides or other chemical are sprayed below the power line, the aerosols conditions will formed and do more risky conditions. 3.6 Vehicles As referred to Bonneville Power Portland, vehicles parked under some high electromotive forces lines, vehicles can be roll up an induced electromotive force if the vehicle is parked on a nonconducting surface such as asphalt or dry lock. It will make flickers or worst electricity in your auto as it is non grounded. A individual will be electrocuted, when he or she is used as a music director to anchor the electromotive force induced. 3. 7 Lightning Lightning will normally strike the highest nearby object, which might be a power line tower or wire. Transmission facilitates are designed to defy lightning work stoppages by imparting them to land at the tower. Death can happen as a individual ‘s organic structure provides a way for current flow doing tissue harm and bosom failure. Other hurts can include Burnss from the discharge generated by the inadvertent contact. These can be particularly unsafe if the victims air passages are affected. Injuries may besides be suffered as a consequence of the physical forces exerted as people may fall from tallness or be thrown considerable distance. 3.8 Tall objects Tall object such as trees and turning flora at high electromotive force lines is risky at 2 facets. First is the semen in contact with the a transmittal line will take to closing down that line and upset the flow of electricity. Second trees and flora can carry on electricity, a state of affairs that can endanger people around the country, animate beings and belongings. The trees can basically go electrified and injured people touches it and might wound or even kill the individual. Electricity can even leap or curve from the transmittal line up to 15 pess off between the power lines and flora. For this intent a 25 pess safety zone is implemented by Bonneville Power ( 2008 ) utilizing the article â€Å" Keeping the manner clear for safe and dependable service † Malaysia as equator and tropical conditions is full of Vegetation and trees in the surrounding of the transmittal lines. Therefore this is really risky in the Malaysia evidences. 3.9 Trespassing Trespassing and hooliganism have been one of the chief issues in Malaysia where 1000000s of ringgit needed to replace and mend the amendss cause by unwanted activities mentioned. Steel beam and other parts of the tower and transmittal lines were taken down by larceny has been a really alarming. 3.10 Pools /Water Pools or pools should be situated near or under the transmittal line because it impedes the workers abilities to run and keep the power lines and presents a possible safety jeopardies to the populace. The jeopardy scope from possible electrical contact with the iwres to dangers that can be brushs during and after lightning work stoppage on transmittal installations. These conditions could be seen at the transmittal lines across paddy Fieldss at the province of KEDAH. Reason why High Voltage Power Line is Still Use Most of the high electromotive force power line usage overhead lines, but the power distribution within the metropolis or crowded topographic points is done utilizing belowground overseas telegrams. Less than one per centum of the entire transmittal lines are placed underground. Although belowground ac transmittal would show a solution to the environmental and aesthetic jobs involved in overhead lines, there are proficient and economical grounds that make the usage of belowground Ac transmittal prohibitive. For low electromotive force distribution applications there are no proficient jobs in utilizing overseas telegrams. The aesthetic and safety demands override the economical considerations in most of the distribution systems and therefore the belowground overseas telegrams are constantly used. High electromotive force power line building is much less expensive than belowground transmittal. Bare wires are used in overhead lines with insularity employed at the points that the wire is supported. Wood or galvanized steel towers are used to back up the music directors. The dielectrics at the music director support points are normally ball and socket porcelain or fiberglass rods covered with skirts made of a compound similar to silicon gum elastic. Lines are good protected against lightning with lightning arresters and shield wires. Bundled music directors are used for 230 kilovolts and above to cut down line reactance and corona effects. There is a trade off between the line losingss and the cost of building the line. Lowering the I2R losingss normally means larger music directors at higher electromotive force operation. This increases the cost of music directors and back uping tower cost. Therefore, the decrease in line loss must be carefully weighed against increased cost. Underground lines are most normally used to feed urban substations in high burden denseness countries. The highest belowground transmittal line electromotive force is 525 kilovolt. Since the cost of an belowground line is 9 to 15 times the cost of an overhead line they are installed merely when they offer a clear advantage or there is no option. The grounds for the high cost are: EHV insularity is expensive. The overseas telegrams must be installed in pipes made of steel or bronze which is dearly-won. Proper chilling with oil circulation is required. Difficult to turn up the mistake and expensive to mend. The overseas telegrams are constructed with oil impregnated paper insularity in many beds. The overseas telegram has a coiling metal wire lesion around the exterior of the insularity to forestall harm to the overseas telegrams while puting. The full overseas telegram is covered with a thin lead sheath that keeps the oil impregnation in the insularity. After the overseas telegram is installed, the pipe is filled with oil. The oil is pumped through the pipe to chill every bit good as insulate the overseas telegram. The oil circulation system includes pumps, filters and oil armored combat vehicles. Sulpher hexaflouride ( SF6 ) is some times used to insulate belowground transmittal overseas telegrams. The popularity of SF6 is increasing because of its simpleness. The belowground transmittal lines are more dependable if decently installed. Adverse consequence that high electromotive force on homo, animate beings, and environment Consequence on Human The preponderance of grounds shows that the low power low frequence electromagnetic radiation associated with family current is really safe, and no biophysical theories for the induction or publicity of malignant neoplastic disease have been substantiated, some research has implicated exposure in a figure of inauspicious wellness effects. These include, but are non limited to, childhood leukemia ( mentions at a lower place ) , grownup leukemia, and neurodegenerative diseases. 5.1.2. Leukaemia and malignant neoplastic disease Harmonizing to a case-control survey conducted in United Kingdom peculiarly in England and Wales, there is an association between childhood leukemia and propinquity of place reference at birth to high electromotive force power lines and the evident hazard extends to greater distance than would hold been expected. About 4 % of kids in England and Wales live within 600meter of high electromotive force lines at birth. If the association is causal, approximately 1 % of childhood leukemia in England and Wales would be properties to these lines though this estimation has considerable statistical uncertainness. A United Kingdom survey of 29,000 instances of childhood malignant neoplastic disease, including 9700 instances of leukemia, found a rise hazard of childhood leukemia in kids who lived within 200m of high electromotive force lines at birth compared with those who lived beyond 600m. There was besides a rebuff increased hazard for those populating 200-600m from the lines at birth as this further than can readily be explained by magnetic Fieldss it may be due to other aetiological factors associated with power line. Harmonizing to Dr. Paul Vailleneuve of the University of Ottawa finds in survey published in February 2002 that those who were exposed to a moderate 6mG of magnetic Fieldss increased by a factor of 12 their odds of developing an agressive encephalon tumour know as glioblastoma multiforme. The Nipponese National Institute for Environmental Studies and the National Cancer Center, in midterm analysis of a joint three-year study undertaking, have concluded kids who are frequently exposed to such electromagnetic moving ridges, emitted from high-potential power lines and some family contraptions, are on norm more than twice as likely to acquire leukemia than those who are non exposed to EMF. These researches shows an indicant there are hazard involved wellness of the public peculiarly people populating nigh High Voltage Power Lines. The authorities and the govern organic structure should take these status earnestly as it involves human life and besides agonies. 5.1.3 Effect of magnetic field toward melatonin ( Sleeping upset ) Harmonizing to Maisch, Podd and Rapley ( 2002 ) , the research has found changeless exposure of magnetic field to single will do kiping disorder.One possible manner a magnetic field could impact slumber is by impacting the production of melatonin, a endocrine produced by pineal secretory organ. The pineal secretory organ is the major control secretory organ over this rhythm, with melatonin production controlled by signals from postganglionic sympathetic fibers ( nerve cells ) connected to the hormone-producing cell of the pineal gland.The firing rate of the endocrine bring forthing varies from daytime and dark. Melatonin is known for its kiping heightening belongingss to guarantee homo would hold a dormant continuance at dark. Harmonizing to Melatonin Hypothesis: Breast Cancer and Use of Electrical Power ( 1997 ) , electromagnetic spectrum peculiarly seeable scope suppresses melatonin synthesis in the pineal secretory organ of all craniates including adult male. Dr Scott Davis of Fre d Hutchinson Cancer Research Center found the higher magnetic field degrees at dark were associated with significantly lower melatonin degrees. Therefore, the researches had come to a conclusive determination that low frequence Fieldss will make dormant perturbation. 5.1.4 Effect on Pregnant adult females and babies The high electromotive force power lines besides give consequence to the pregnant adult females and her babies. For an illustration a survey by Dr. De-Kun Li ( January 2002 ) shows that, a treble addition in overall self-generated abortions and a sextuple addition in self-generated abortions happening before the tenth hebdomad of gestation is associated with even fleeting exposure to magnetic Fieldss greater than 16 milligram. Similar consequences were found in a separate paper on self-generated abortions prepared for the undertaking by G. M. Lee which is printed in the same issue. Harmonizing to a intelligence study in New Scientist of January 10, 2002, Li ‘s consequences caused a California Health Services section scientist, Raymond Neutra, to review his 1991 survey of 727 adult females. Originally, his group ‘s survey had measured mean magnetic field exposures and with inconclusive consequences. However, when Neutra late reanalyzed the information from his earlier surv ey, he discovered the consequences were similar to Li ‘s. Womans exposed to top out magnetic field degrees greater than 14 milligrams doubled their hazard of abortion over those who had no such exposure. Consequence on the Environment High Voltage Power Lines: Power lines deliver electricity ( normally at 50 or 60 Hz ) and may cross 100s of kilometers. Degrees of electromagnetic Fieldss ( EMF ) from human-made beginnings have increased steadily over the past 50-100 old ages. Most EMF exposures come from increased usage of electricity and new engineerings. In the past decennaries, possible inauspicious effects from EMF exposure on human wellness have been an of import subject of research. However, small has been published about the impact of EMF on the natural terrestrial and aquatic environment. The World Health Organization ( WHO ) is turn toing this issue through the International EMF Project. One of the Project ‘s aims is to supply advice to national governments and others on EMF wellness and environmental effects and protective steps or actions if needed. This information sheet summarizes the current scientific apprehension on the effects of exposure to EMF Fieldss on the life environment, across the electromagnetic spectrum in the frequence scope 0-300 GHz. This scope covers all frequences that are emitted into the environment through usage of EMF engineering. Recommendations are besides given for farther research to make full spreads in cognition needed to better buttocks EMF environmental impacts. Awareness of any environmental impacts of EMF is of import to guarantee the saving of tellurian and marine ecosystems, which form the footing for sustainable development. Protection of the environment and preservation of nature have become affairs of great involvement to the populace, every bit good as to authoritiess. Such involvement is frequently expressed as concern over possible environmental impacts of big engineering undertakings, such as dikes, atomic power workss, and radiofrequency senders. Several undertakings have been capable to public force per unit areas on environmental evidences, with EMF being one but non needfully the lone issue. For illustration, a proposed high frequence ( HF ) wireless sender for the Voice of America in Israel, which would hold been the universe ‘s largest wireless station, was blocked from building on environmental evidences, in portion related to concerns about possible effects of wireless frequence Fieldss on migrating birds. Public concern about environmental exposure to EMF has ranged from claims of decreased milk production in cattles croping under power lines to damage to trees nigh high power radio detection and rangings. Such concerns might besides impact the development of new engineering: several programs have been proposed since the late sixtiess for bring forthing electric power in infinite by revolving arrays of solar panels. Large sums of electricity generated by such solar power orbiters would be transmitted to ample aerials on the land. In add-on to get the better ofing proficient troubles, this and other new engineerings would hold to derive public credence. Consequence on the Animals Most surveies of EMF effects in animate beings have been conducted to look into possible inauspicious wellness effects in worlds. These are normally performed on standard research lab animate beings used in toxicological surveies, e.g. rats and mice, but some surveies have besides included other species such as like short-living flies for the probe of genotoxic effects. The topic of this information sheet, nevertheless, is whether Voltage can hold harmful impacts on species of wild and domestic animate beings. Under consideration are: Speciess, in peculiar certain fish, reptilians, mammals and migratory birds, which rely on the natural ( geomagnetic ) inactive magnetic field as one of a figure of parametric quantities believed to be used for orientation and navigational cues Farm animate beings ( e.g. swine, sheep or cowss ) croping under power lines ( 50/60 Hz ) or in the locality of broadcast medium aerials Flying zoologies, such as birds and insects, this may go through through the chief beam of high power radio-frequency aerials and radio detection and ranging beams or through high strength ELF Fieldss near power lines. Surveies performed to day of the month hold found small grounds of EMF effects on zoologies at degrees below ICNIRP ‘s guideline degrees. In peculiar, there were no inauspicious effects found on cowss croping below power lines. However, it is known that flight public presentation of insects can be impaired in electric Fieldss above 1kV/m, but important effects have merely been shown for bees when electrically conductive urtications are placed straight under power lines. Un-insulated un-earthed music directors placed in an electric field can go charged and cause hurt or interrupt the activity of animate beings, birds and insects.5.0 LEGAL EleCtrical safety REQUIREMENTSUnderstanding the consequence of electrical jeopardies such as decease and devastation of belongings, assorted attempts have been made by the authorities to guarantee the safety of users/workers and the proper use of electricity through statute laws and enforcement. Among the statutory commissariats related to the safety usage of electricity are:Electricity Supply Act 1990Electrical Supply Regulations 1994SIRIM Standards for Electrical EquipmentOoccupational Safety and Health Act 1994 ( OSHA 1994 )Legislation and enforcement of these Acts and Regulations guarantee the safety of users. High electromotive force is defined by the DOE Electrical Safety Guidelines as:Over 600 Vs, but any electromotive force above 50 Vs should be considered life threatening, and treated consequently. Normally high electromotive force circuits and equipment are marked with Hazard Signs. Mentions on High Voltage can be found in: I ) Occupational safety and health administration Defines high electromotive force and lists preparation demands and safe work patterns ( including attack distances ) . two ) NEC NFPA 70 â€Å" National Electrical Code † provides extra information on high electromotive force equipment. three ) OTHER NFPA 70E â€Å" Standard for Electrical Safety Requirements for Employee workplaces † provides elaborate safe attack distances for working on high electromotive force equipment. four ) From Electrical Supply Act ( Syarikat Pengganti ) states the distance from the land to the transmittal varies harmonizing to the electromotive force value of the transmittal line. There are three status references from the route, other so the route and the location could non be reached by the route bole. Table 1 Voltage system between the music director On the route ( Meter ) Other than on the route ( Meter ) Location could non reached by the route ( Meter ) Not more than 600 Volts 5.49 5.18 4.57 More than 600 less than 11,000 V 5.79 5.49 4.88 More than 11,000 V less than 66,000 V 6.10 6.10 5.18 More than 66,000 V less than 132,000 V 6.70 6.70 5.79 More than 132,000 V less than 275,000 V 7 7 7 More than 275,000 V 7.3 7.3 7.3 Harmonizing to Strauss and Bernard ( 1991 ) , some of the federal Torahs in United States do non modulate electric and magnetic Fieldss due to public deductions and besides multi billion dollar electricity industries in the States. Some of the new Torahs are non based on scientific dictum about safe degree of magnetic filed exposure but instead on the premise that the position quo is publically acceptable. With this statement, In Malaysian ‘s the ordinances and act on the High Voltage Power Lines are non truly specific and all conditions could be change by the Minister in charge. Decision As refer to all the risky possibilities, yet still there are non proved status the danger of the magnetic moving ridge towards human wellness. There are a few researches shown there is a really high possibility of developing malignant neoplastic disease due high electromotive force transmittals lines but none of the research is definite and conclusive. Besides malignant neoplastic disease, a research has found low frequence magnetic moving ridge could strip homo ‘s sleeping form during dark clip because of stamp downing the melatonin endocrine. Other than that, the status or location of the transmittal line in Malaysia has lid concerns when the transmittal lines fluxing through the paddy field, the wood and besides the lodging estate. As for the ordinance concerns, due to none of the researches shown the danger of magnetic moving ridge in malignant neoplastic disease and other risky status, safeguards of these safety conditions are neglected. Equally long as there is no complain or human death from the populace, the authorities assume it has reach the safety demands. Therefore, we as the citizens or public, have to go a victim foremost before any Act or Regulation would be drafted to avoid such state of affairs. Make bear in head, it is non prevention but simply an turning away from the authorization. As more underdeveloped states are traveling frontward towards industrialization, more power lines are needed and more power workss will be build to for coevals. Therefore is our female parent Earth in the save from these magnetic moving ridges? Will it destruct our Earth and human sort or the mutational conditions has reached its extremum? No organic structure can reply it. As what a politician would state, there is non danger unless there are marks of decease or irreversible conditions. Uncertainty is the most deathly status compared to certainty.

Position of the Music Industry Prior to Introduction of Internet Essay

In the music industry prior to the introduction of internet marketing there were different roles being played by different actors of the market. The usual way a product is prepared for market is to contract the artists. The artists who were the content providers record materials which are either their own or provided to them by other writers. This is clearly depicted in the figure below. Traditional Value Chain in the Music Industry Source: John B. Meisel and Timothy S. Sullivan The recordings will be done on the basis of the contracts entered into with the recording companies. Hence the power and control over the supply of the product remained with the record company. The recording company thus would be regarded as the holder of the major item of value in the supply chain being the exclusive rights over the recorded artists’ content. (Hardaker and Graham, 2001) Most of the part of the distribution is in the hands of the record companies and they also retain the rights to select the suppliers. The distribution and supplier selection is based on the record companies’ perception about the quality of the recording and the music, past reputation of the suppliers and the contract price for the recording. In return for the content in the form of recording, the artist is compensated by the provision of promotions for the recording and its merchandising in connection with the sales there of and the distribution of the content as a saleable commodity – CD for example. It was usual in the traditional music industry that the major record companies have their own distribution channels and businesses. Hence it would become necessary for a retailer to source his music products from different sources. Sometimes the retailer may have to place orders with major record companies and up to 20 other firms from the independent sector. The new releases of music albums or other sales of the record companies are usually handled by the wholesalers. If the retailer would like to follow the wholesaler route then he might have to order through only one wholesaler. The main wholesalers also offer another service called ‘rack jobbing’ which is a different method of supply being adopted by them. The function of a rack jobber includes the supply of complete package that contains records and other promotional and display materials. It is also the duty of the wholesaler to keep a regular stock usually on a sale or exchange basis. Just as the advancement in the telecommunication had its effect on all the other sectors from airline reservations to banking and related financial services the music recording industry has also been severely impacted both positively and negatively observes Eric de Fontenay. In fact the impact of internet on the music industry is much more profound than on any other industries. Despite the fact that the entertainment related products and services have taken their own time to develop and take advantage of the improvements in digital technology over the decades, during the intervening period the overall structure of the industry has remained dormant. The reasons for the industry to remain without major changes can be traced to the following reasons: 1. The cost of creation of content has always remained higher and this prohibited any new entrants in to the industry. 2. The structure of content ownership and rights of licensing system remained unaltered thereby keeping the structure of the industry in tact. 3. There has been a continuous necessity for the presence of a distribution network almost everywhere in the world irrespective of the geographical barriers. This has restricted the existing firms to make any changes in the structure. There was no possibility of new firms entering the market in view of the high capital intensive nature. 4. Similarly there had always been a constant scarcity for the distribution networks which also prevented any new forms of distribution or change in the structure of the distribution networks. (Eric de Fontenay) The internet has affected the music industry in so many ways. It has made the industry incur additional costs in completely restructuring itself. Further the internet has reduced the entry barriers. This was possible by a considerable increase in the number of downstream outlets having varied nature. At the same time the internet has provided the actors in the upstream end to enjoy greater control over the aspects of content ownership, production and distribution. This has created a distinct fear in the record labels that they cannot eliminate the possibility of getting bypassed by both the markets in the downstream and upstream. This impact has created the following reaction on the part of the traditional industry actors. They tried to impose the existing rules and procedures to the new medium so that they could exercise the same leverage and control over the market. The process by which they attempted to do it involves a twin aspects strategic approach. At one end they used legal channels to restrict the availability and use of the new technology in the Industry. On the other end they adopted new technologies to tackle the potential legal threats that would affect the control derived by them from the traditional systems. This strategy backfired and left them high and dry in the market while new information technology players like AOL, Microsoft, E Music and MP3 took advantage of the stalemate. They reacted aggressively by building their infrastructure and systems for the online marketing and distribution of music. They also involved themselves in the retailing of music over internet. The distribution of revenues in the music industry involves the portion of the performer. As per the contract terms the performer is to be paid a portion of the revenue each time there is a sale of the record. Before the money is paid to the performer the revenue is to be apportioned towards the expenses incurred by the company for marketing and distribution. This gives an opportunity for the artists to earn considerable amounts from the sale of products. For gaining maximum revenue the artists should control the publishing rights to their songs or they have the capacity to negotiate contracts with terms that are favourable to the artists. In the case of revenue distribution Internet has its impact on the industry in the following respects.

CHAPTER FIVE: COST ESTIMATION Introduction When managers make decisions they need to compare the costs (and benefits) among alternative actions. In this chapter, we discuss how to estimate the costs required for decision making (Lanen, 2008). Learning Objectives: According to Lanen (2008), after completing Chapter 5 you should: 1. Understand the reasons for estimating fixed and variable costs. 2. Estimate costs using engineering estimates. 3. Estimate costs using account analysis. 4. Estimate costs using statistical analysis. 5. Interpret the results of regression output. 6.Identify potential problems with regression data. 7. Evaluate the advantages and disadvantages of alternative cost estimates. 8. (Appendix A) Use Microsoft Excel to perform a regression analysis. 9. (Appendix B) Understand the mathematical relationship describing the learning phenomenon. Why Estimate Costs? Managers make decisions and need to compare costs and benefits among alternative actions. Good decision requ ires good information about costs, the better these estimates, the better the decision managers will make (Lanen, 2008).. Key Question What adds value to the firm? Read this  Financial StatementsGood decisions. You saw in Chapters 3 and 4 that good decisions require good information about costs. Cost estimates are important elements in helping managers make decisions that add value to the company (Lanen, 2008). Learning Objective One: Understand the reasons for estimating fixed and variable costs The reasons for estimating fixed and variable costs The basic idea in cost estimation is to estimate the relation between costs and the variables affecting costs, the cost drivers. We focus on the relation between costs and one important variable that affect them: activity (Lanen, 2008).Basic Cost Behavior Patterns By now you understand the importance of cost behavior. Cost behavior is the key distinction for decision making. Costs behave as either fixed or variable (Lanen, 2008). Fixed costs are fixed in total, variable costs vary in total. On a per-unit basis, fixed costs vary inversely with activity and variable costs stay the same. Are you gettin g the idea? Cost behavior is critical for decision making. The formula that we use to estimate costs is similar cost equation: Total costs = fixed costs + {variable cost per unit} number of unitsT c = f + {v} x |With a change in Activity |In Total |Per Unit | |Fixed Cost |Fixed |Vary | |Variable |Vary |Fixed |What Methods are used to Estimate Cost Behavior? Three general methods used to estimate the relationship between cost behavior and activity levels that are commonly used in practice: Engineering estimates, Account analysis & Statistical methods (Such as regression analysis) (Lanen, 2008). Results are likely to differ from method to method. Consequently, it’s a good idea to use more than one method so that results can be compared. These methods, therefore, should be seen as ways to help management arrive at the best estimates possible.Their weakness and strengths require attention. Learning Objective Two: Estimate costs using engineering estimates. Engineering Estimates C ost estimates are based on measuring and then pricing the work involved in a task. This method based on detailed plans and is frequently used for large projects or new products. This method often omits inefficiencies, such as downtime for unscheduled maintenance, absenteeism and other miscellaneous random events that affect the entire firm (Lanen, 2008). Identify the activities involved Labor |Rent |Insurance |Time |Cost | Advantages of engineering estimates |Details each step required to perform an operation |Permits comparison of other centers with similar operations | |Identifies strengths and weaknesses. | | Disadvantages of engineering estimates 1. Can be quite expensive to use. Read also Recording General Fund Operating Budget and Operating TransactionsLearning Objective Three: Estimate costs using account analysis. Account Analysis Estimating costs using account analysis involves a review of each account making up the total costs being analyzed and identifying each cost as either fixed or variable, depending on the relation between the cost and some activity. Account analysis relies heavily on personal judgment. This method is often based on last period’s cost along and is subject to managers focusing on specific issues of the previous period even though these might be unusual and infrequent(Lanen, 2008) .Example: Account Analysis (Exhibit 5. 1) |3C Cost Estimation Using Account Analysis | |Costs for 360 Repair Hours | |Account |Total |Variable Cost |Fixed Cost | |Office Rent $3,375 |$1,375 |$2,000 | |Utilities |310 |100 |210 | |Administration |3,386 |186 |3,200 | |Supplies |2,276 |2,176 |100 | |Training |666 |316 |350 | |Other |613 |257 |356 | |Tot al |$10,626 |$4,410 |$6,216 | |Per Repair Hour |$12. 25 ($4,410 divided by 360 repair-hours) | 3C Cost Estimation Using Account Analysis (Costs at 360 Repair-Hours. A unit is a repair- hour) Total costs = fixed costs + {variable cost per unit} number of unitsT c = f + {v} x |$10,626 = $6,216 + $12. 25 (360) |$10,626 = $6,216 + $$4,410 | Costs at 520 Repair-Hours Total costs = fixed costs + {variable cost per unit} number of units |Tc = $6,216 + {$12. 25} 520 |Total costs = $6,216 + $ $6,370 |$12,586 = $6,216 + $ $6,370 | Advantage of Account Analysis 1. Managers and accountants are familiar with company operations and the way costs react to changes in activity levels. Disadvantages of Account Analysis 1. Managers and accountants may be biased. 2.Decisions often have major economic consequences for managers and accountants. Learning Objective Four: Estimate costs using statistical analysis. The statistical analysis deals with both random and unusual events is to use several periods o f operation or several locations as the basis for estimating cost relations . We can do this by applying statistical theory, which allows for random events to be separated from the underlying relation between costs and activities. A statistical cost analysis analyzes costs within the relevant range using statistics. Do you remember how we defined relevant range? A relevant range is the range of activity where a cost estimate is valid.The relevant range for cost estimation is usually between the upper and lower limits of past activity levels for which data is available (Lanen, 2008). Example: Overhead Costs for 3C ( Exhibit 5. 2) The following information is used throughout this chapter: Here we have the overhead costs data for 3C for the last 15 months. Let’s use this data to estimate costs using a statistical analysis. |Month |Overhead Costs |Repair-Hours |Month |Overhead Costs |Repair-Hours | |1 |$9,891 |248 |8 |$10,345 |344 | |2 $9,244 |248 |9 |$11,217 |448 | |3 |$13,200 | 480 |10 |$13,269 |544 | |4 |$10,555 |284 |11 |$10,830 |340 | |5 |$9,054 |200 |12 |$12,607 |412 | |6 |$10,662 |380 |13 |$10,871 |384 | |7 |$12,883 |568 |14 |$12,816 |404 | | | | |15 |$8,464 |212 | A. Scattergraph Plot of cost and activity levelsDoes it look like a relationship exists between repair-hours and overhead costs? We will start with a scatter graph. A scatter graph is a plot of cost and activity levels. This gives us a visual representation of costs. Does it look like a relationship exists between repair-hours and overhead cost? We use â€Å"eyeball judgment† to determine the intercept and slope of the line. Now we â€Å"eyeball† the scatter graph to determine the intercept and the slope of a line through the data points. Do you remember graphing our total cost in Chapter 3? Where the total cost line intercepts the horizontal or Y axis represents fixed cost. What we are saying is the intercept equals fixed costs. Also read Current Liabilities and Payroll AccountingThe slope of the line represents the variable cost per unit. So we use â€Å"eyeball judgment† to determine fixed cost and variable cost per unit to arrive at total cost for a given level of activity. As you can imagine, preparing an estimate on the basis of a scatter graph is subject to a high level of error. Consequently, scatter graphs are usually not used as the sole basis for cost estimates but to illustrate the relations between costs and activity and to point out any past data items that might be significantly out of line. B. High-Low Cost Estimation A method to estimate costs based on two cost observations, usually at the highest and lowest activity level.Although the high-low method allows a computation of estimates of the fixed and variable costs, it ignores most of the information available to the analyst. The high-low method uses two data points to estimate costs (Lanen, 2008). Another approach: Equations V = Cost at highest activity – Cost at lowest activity Highest activity – Lowest activity F = Total cost at highest activity level – V (Highest activity) Or F = Total cost at lowest activity level – V (Lowest activity) Let’s put the numbers in the equations | | | |V = $12,883 – $9,054 |V = $10. 0/RH | |568 – 200 | | F = Total cost at highest activity level – V (Highest activity) F = $12,883 – $10. 40 (568), F= $6,976 Or F = Total cost at lowest activity level – V (Lowest activity) F = $9,054 – $10. 40 (200) Rounding Difference C. Statistical Cost Estimation Using Regression Analysis Statistical procedure to determine the relationship between variables High-Low Method: Uses two data points. Regression analysis Regression is a statistical procedure that uses all the data points to estimate costs. [pic] Regression AnalysisRegression statistically measures the relationship between two variables, activities and costs. R egression techniques are designed to generate a line that best fits a set of data points. In addition, regression techniques generate information that helps a manager determine how well the estimated regression equation describes the relations between costs and activities (Lanen, 2008). We recommend that users of regression (1) fully understand the method and its limitations (2) specify the model, that is the hypothesized relation between costs and cost predictors (3) know the characteristics of the data being tested (4) examine a plot of the data .For 3C, repair-hours are the activities, the independent variable or predictor variable. In regression, the independent variable or predictor variable is identified as the X term. An overhead cost is the dependent variable or Y term. What we are saying is; overhead costs are dependent on repair-hours, or predicted by repair-hours. The Regression Equation |Y = a + bX |Y = Intercept + (Slope) X |OH = Fixed costs + (V) Repair-hours | You alr eady know that an estimate for the costs at any given activity level can be computed using the equation TC = F + VX. The regression equation, Y= a + bX represents the cost equation.Y equals the intercept plus the slope times the number of units. When estimating overhead costs for 3C, total overhead costs equals fixed costs plus the variable cost per unit of repair-hours times the number of repair-hours. We leave the description of the computational details and theory to computer and statistics course; we will focus on the use and interpretation of regression estimates. We describe the steps required to obtain regression estimates using Microsoft Excel in Appendix A to this chapter. Learning Objective Five: Interpret the results of regression output. Interpreting Regression [pic] Interpreting regression output allows us to estimate total overhead costs.The intercept of 6,472 is total fixed costs and the coefficient, 12. 52, is the variable cost per repair-hours. Correlation coefficie nt â€Å"R† measures the linear relationship between variables. The closer R is to 1. 0 the closer the points are to the regression line. The closer R is to zero, the poorer the regression line (Lanen, 2008). Coefficient of determination â€Å"R2† The square of the correlation coefficient. The proportion of the variation in the dependent variable (Y) explained by the independent variable(s)(X). T-Statistic The t-statistic is the value of the estimated coefficient, b, divided by its standard error. Generally, if it is over 2, then it is considered significant.If significant, the cost is NOT totally fixed. The significant level of the t-statistics is called the p-value. Continuing to interpret the regression output, the Multiple R is called the correlation coefficient and measures the linear relationship between the independent and dependent variables. R Square, the square of the correlation cost efficient, determines and identifies the proportion of the variation in the dependent variable, in this case, overhead costs, that is explained by the independent variable, in this case, repair-hours. The Multiple R, the correlation coefficient, of . 91 tells us that a linear relationship does exist between repair-hours and overhead costs.The R Square, or coefficient of determination, tells us that 82. 8% of the changes in overhead costs can be explained by changes in repair-hours. Can you use this regression output to estimate overhead costs for 3C at 520 repair-hours? Multiple Regressions Multiple regressions are used when more than one predictor (x) is needed to adequately predict the value (Lanen, 2008). For example, it might lead to more precise results if 3C uses both repair hours and the cost of parts in order to predict the total cost. Let’s look at this example. |Predictors: |X1: Repair-hours |X2: Parts Cost | 3C Cost Information | |Month |Overhead Costs |Repair-Hours ( X1) |Parts ( X2) | |1 |$9,891 |248 |$1,065 | |2 |$9,244 |248 |$1,452 | |3 |$13,200 |480 |$3,500 | |4 |$10,555 |284 |$1,568 | |5 |$9,054 |200 |$1,544 | |6 |$10,662 |380 |$1,222 | |7 |$12,883 |568 |$2,986 | |8 |$10,345 |344 |$1,841 | |9 |$11,217 |448 |$1,654 | |10 |$13,269 |544 |$2,100 | |11 |$10,830 |340 |$1,245 | |12 |$12,607 |412 |$2,700 | |13 |$10,871 |384 |$2,200 | |14 |$12,816 |404 |$3,110 | |15 |$8,464 |212 |$ 752 | In multiple regressions, the Adjusted R Square is the correlation coefficient squared and adjusted for the number of independent variables used to make the estimate. Reading this output tells us that 89% of the changes in overhead costs can be explained by changes in repair-hours and the cost of parts. Remember 82. % of the changes in overhead costs were explained when one independent variable, repair-hours, was used to estimate the costs. Can you use this regression output to estimate overhead costs for 520 repair-hours and $3,500 cost of parts? Learning Objective Six: Identify potential problems with regression data. Implementation P roblems It’s easy to be over confident when interpreting regression output. It all looks so official. But beware of some potential problems with regression data. We already discussed in earlier chapters that costs are curvilinear and cost estimations are only valid within the relevant range. Data may also include outliers and the relationships may be spurious. Let’s talk a bit about each. Curvilinear costs |Outliers |Spurious relations |Assumptions | 1. Curvilinear costs Problem: Attempting to fit a linear model to nonlinear data. Likely to occur near full-capacity. Solution: Define a more limited relevant range (example: from 25 – 75% capacity) or design a nonlinear model. If the cost function is curvilinear, then a linear model contains weaknesses. This generally occurs when the firm is at or near capacity. The leaner cost estimate understates the slope of the cost line in the ranges close capacity. This situation is shown in exhibit 5. 5. 2. Outliers Problem: Outlier moves the regression line.Solution: Prepare a scatter-graph, analyze the graph and eliminate highly unusual observations before running the regression. Because regression calculates the line that best fits the data points, observations that lie a significant distance away from the line could have an overwhelming effect on the regression estimate. Here we see the effect of one significant outlier. The computed regression line is a substantial distance from most of the points. The outlier moves the regression line. Please refer exhibit 5. 6. 3. Spurious or false relations Problem: Using too many variables in the regression. For example, using direct labor to explain materials costs.Although the association is very high, actually both are driven by output. Solution: Carefully analyze each variable and determine the relationship among all elements before using in the regression. 4. Assumptions Problem: If the assumptions in the regression are not satisfied then the regression i s not reliable. Solution: No clear solution. Limit time to help assure costs behavior remains constant, yet this causes the model to be weaker due to less data. Learning Objective Seven: Evaluate the advantages and disadvantages of alternative cost estimation methods. Statistical Cost Estimation Advantages 1. Reliance on historical data is relatively inexpensive. 2.Computational tools allow for more data to be used than for non-statistical methods. Disadvantages 1. Reliance on historical data may be the only readily available, cost-effective basis for estimating costs. 2. Analysts must be alert to cost-activity changes. Choosing an Estimation Method Each cost estimation method can yield a different estimate of the costs that are likely to result from a particular management decision. This underscores the advantage of using more than one method to arrive at a final estimate. Which method is the best? Management must weigh the cost-benefit related to each method (Lanen, 2008). Estimat ed manufacturing overhead with 520 repair-hours and $3,500 parts costs *.The more sophisticated methods yield more accurate cost estimates than the simple methods. |Account Analysis = $12,586 |High-Low = $12,384 |Regression= $12,982 |Multiple Regression= $13,588* | Data Problems Missing data Outliers Allocated and discretionary costs Inflation Mismatched time periods No matter what method is used to estimate costs, the results are only as good as the data used. Collecting appropriate data is complicated by missing data, outliers, allocated and discretionary costs, inflation and mismatched time periods. Learning Objective Eight: (Appendix A) Use Microsoft Excel to perform a regression analysis. Appendix A: Microsoft as a ToolMany software programs exist to aid in performing regression analysis. In order to use Microsoft Excel, the Analysis Tool Pak must be installed. There are software packages that allow users to easily generate a regression analysis. The analyst must be well school ed in regression in order to determine the meaning of the output! Learning Objective Nine: (Appendix B) Understand the mathematical relationship describing the learning phenomenon. Learning Phenomenon Leaning phenomenon refers to the systematic relationship between the amount of experience in performing a task and the time required to perform it. The learning phenomenon means that the variable costs tend to decrease per unit as the volume increase. Example: | |Unit |Time to Produce |Calculation of Time | |First Unit |100 hours |(assumed) | |Second Unit |80 hours |(80 percent x 100 hours | |Fourth Unit |64 hours |(80 percent x 80 hours | |Eighth Unit |51. hours |(80 percent x 64 hours | |Impact: Causes the unit price to decrease as production increases. This implies a nonlinear model. | Another element that can change the shape of the total cost curve is the notion of a learning phenomenon. As workers become more skilled they are able to produce more output per hour. This will impact the total cost curve since it leads to a lower per unit cost, the higher the output. Chapter 5: END!!

W3Qop - Essay Example t. c. The sites are applied by companies to promote sales through the internet. The people who visit these sites can create their profile, which allows them to display their interests and thoughts regarding various issues. Companies utilize the opportunity to identify consumer’s views regarding their products. They use the sites to promote brand awareness especially when a new brand is launched. Consumer confidence is increased when they interact through these sites. They get to know how the views of other consumers and also their questions can be addressed in unison (Hackler & Saxton, 2007). Social networks can be used to boost business especially when the marketing campaigns are designed to match the business objectives. The advertisements target specific market segments ensuring that their needs are met. The sites are significant in meeting the needs of a wide customer base especially due to the fact that the use of internet is growing rapidly globally. Consumers are allowed to interact in online forums wherever they are, and they create a large audience for the marketers. The swiftness through which information is passed to all consumers is significant in making quick sales than the conventional forms of marketing. Moreover, the marketers have an opportunity to demonstrate to the consumers through video clips or demos. The sites are flexible and the marketers can change the content fast to suit consumer demands. Value addition can be accomplished through allowing the consumers to vote for their interests to be integrated in the product. In essence, the social network s have helped businesses to make a major milestone in promoting their products (Turban et al. 2008). Â   Managers do not like problems especially due to the time they consume making it difficult to accomplish good plans. Problems generate uncertainties in business and they always seem imminent. When managers identify problems, they ensure that they are

Attend an online religious service and describe prior misconceptions Assignment

Attend an online religious service and describe prior misconceptions - Assignment Example The teacher did indeed wear traditional robes, but I was surprised to note that not a single attendee wore anything even resembling a saffron colored robe. Jeans, sweatshirts and western dress was the norm. I learned from watching this that there is no proscribed dress code for attending a Buddhist teaching service, at least not with this teacher. The setting looked like a conference room that was equipped with a microphone so the teacher’s voice filled the room. The room was bright and airy without a single candle. A second misconception I had about Buddhist teaching was that it was more interactive. For some reason, I always pictured the teaching of The Buddha occurring as conversations under that tree. I was surprised to find that the flow of the teaching ceremony closely resembled that of other religions I have attended. In a Christian church, a rough outline of the worship service consists of an invocation, a hymn; the pastor’s message another hymn and then a bened iction. The same was true for this teaching session. The session opened with chanting, the teacher spoke for about an hour and a half on the link between common sense, philosophy and realization, and then several sessions of meditation concluded the meeting. The purposes of the meditation and chanting seemed to serve the same purposes as prayer and congregational singing in a Christian service. I was surprised to see that the two religions operated in such similar ways. A final misconception that disappeared by watching this video was the idea that Buddhist teachings were somehow delivered in riddles. I expected the instruction to be more mystical, more open to interpretation and opaque. What I witnessed was clear instruction on the link between unhappiness and want, desire and ego. The teacher clearly taught how common sense without philosophical depth leads to a shallow existence without a realization of one’s self and the world around us. The teaching was clear, even thoug h the teacher had limited English proficiency. After watching this service, I feel that I have a better grasp on how Buddhists apply the principles of their religion in the modern world. I understood the basic teaching of the Buddha, but I understood them in abstract. This teacher was very adept at using real life situation that occur in modern times to illustrate how to apply the teachings in the lesson. Following the themes of common sense, philosophy and realization, he spoke candidly about applying the teachings of The Buddha in our interpersonal relationships, our relationships with material goods and out perception of ourselves. I learned that Buddhist teachings are compatible with everyday life in a way that I did not understand before viewing this video. The teacher used humor often in his teaching, which was unexpected for me and seemed to make everything updated. I understood that The Buddha taught about how to be happy by overcoming our own desires for wealth, fame and po wer, but I don’t think I realized just how incredibly ingrained these desires are in each one of us, including myself. I gained a deeper understanding through this video of the mindset that is expected in Buddhism. The teacher taught that depending on common sense alone to get us through difficult times alone could lead us to unhappiness because we become self-satisfied and self-centered. We must also have a philosophy

Wild Frontier Pt. 3 - Assignment Example WSS as it integrates the intranet and web applications will make it easier for the company to deploy their applications. The organization’s intranet can be accessed from anywhere by its employees. Uploading the web applications on the intranet makes it easier for the remote offices to access these applications without them necessarily being installed on the local machine (Husman, 2007). Windows SharePoint Services are used for creation, management and sharing of documents. Like any other organization, Wild Frontier has several departments and these departments are interconnected both in the headquarters and field offices. The finance department in the remote office should be able to access the records at the headquarters, and this can be accomplished using SharePoint. Employee A at the headquarters will upload a document on the SharePoint workspace of the finance department and Employee B in one of the field offices accesses it via the intranet. On this very document, Employee B can make changes and save these changes (Husman, 2007). This means that there are two different people working on the same document- each at a time- this avoids duplication of work. The advantage is that SharePoint has document versions and if one does not like the current edited version, they can revert back to the previous version without redoing the whole document. The management wants to make use of the same number of printers with the increased taskforce and field offices. To be able to accomplish this, the printers will have to be connected on a network. Having the printers connected to a common network will make it easier for the employees to print on any machine in the building as long as the printer is configured on the user’s machine or laptop. Additionally, if the printers enable the users to print wirelessly then this makes the whole printing process much faster and convenient. This will see to it that some of the printers are moved

Reaction Paper - Essay Example Stiglitz emphasizes the problem of inequality and considers it to be the main aspect that prevents the economy of the United States from the recovery. The author is sure that it is inequality that does not allow American children to have equal opportunities and to develop. He argues that the parents of a great number of children will not be able to pay the loan they take to provide their child with education in all ones born days (Stiglitz). The author of the third article not only states that inequality inhibits the growth but also wants to reveal the reasons of inequality. According to the author, during last several years the demand for goods and services declined as only rich people were able to pay for them. He explains it by the fact that the development of technology made many people loose the job as the technologies replaced people at the workplace. This led to the high level of unemployment

Section 4 of the paper discusses in depth the acquisition strategies of Vodafone. An in-depth analysis of pre-acquisition rationale and steps involved therein like analysis of strategic fit, valuation methods and due diligence has been done. The post integration efforts have also been detailed in this section. An attempt has been made to apply the Haspeslagh and Jemison Framework in the post integration efforts. The discussion in this section extends to gauging the overall effectiveness of the acquisition strategy. Any organization with a global footprint can pursue a global strategy, a multi-domestic strategy or a transnational strategy. Vodafone’s choice of International strategy has been discussed in Section 5 of this paper. An organization is able to compete successfully in the marketplace if it can deliver superior value to its customer vis-Ã  -vis the rival firms. The creation of this value entails a series of activities which have been referred to as the value chain by Michael Porter. The arrangement and completion of various activities and their linkages determine whether the firm will be able to manufacture a product for which the customer is willing to pay a price that is higher than the cost of producing the product. The activities in the value chain are divided into two broad categories namely primary activities and support activities (Grant, 2010, Pg 111) . The primary activities enable the manufacturing of the product that the organization intends to sell in the market. This offering may be goods (tangible products) like

Midterm Assignment Example | Topics and Well Written Essays - 1250 words

Midterm - Assignment Example Some of the code’s provisions do not sound fair, for example, a code number 2. It states that an employee of Ashland University, who has responsibilities with respect to education loans, or any agent, shall not accept any gift from a lender, guarantor, or servicer of education loans. This is quite unfair owing to the fact that, at times, an employee can be awarded just for services well rendered and refusal to accept it might be taken as rudeness by the giver (Holloway, 2011). A loan can also be given to an employee on the basis of need and not on any favor’s basis; hence, it turns out to be inconsiderate on the side of the employees (Holloway, 2011). Code number 6 forbids the institution from borrowing loans from various parties. This happens to be quite unfair basing on the fact that once in a while the bank may happen to be down financially and the loan might be of great help. There is no crime in asking for the loan as long as the payment is guaranteed. Is any part of the code routinely violated? The rule on accepting gifts from lenders is often violated. Why do you think these violations occur? The human part of a person finds it hard to resist a gift just because of professionalism. At times, one gets into a problem and is in a real need of a loan and the only option is the forbidden party, hence goes ahead and breaks the code. What are the usual consequences of such violations? The consequences of such violations can be tough. The most common is being sacked.

Sexual Harassment in the workplace Research Paper

Sexual Harassment in the workplace - Research Paper Example The key terminologies essential when tackling such a topic include; Sexism-This can be described as an attitude based perception about a person of different sex. For instance, a man thinking that a woman is weak and emotional or a woman thinking that a man is a chauvinist. Sex discrimination-This is manifested in the scenario where an employee tend to be treated differently at the work place because of their sex. Quid Pro Quo-This when decision on employing somebody are based on whether they agree to accept fulfilling sexual demands or not. Sexual harassment in the workstation can have severe influences for both the workers who have experienced it secondhand and the harassed person. The impact of sexual harassment to an employee can be numerous and disastrous. Areas, which have drawn interest of researches in the recent past, are whether sexual harassment is on the rise at work places or other new ways of harassment have emerged. This is based on the fact that, the surges in technolo gy use and harassment from same sex persons have been reported in the recent past. It is of equal importance to note that sexual harassment is not limited to a singular profession but the vice cuts across all career stations (Boland 34-35). Recent statistics by EEOP (Equal Employment Opportunity Commission) divulge more information about the complaints. It has been noted that most of the sexual harassment occurrences largely go unreported. However, according to EEOC, one fact observation that was evident is the increase of cases reported in the last decade. This brings in a paradox since more stringent regulations have been put in place to inhibit occurrences of sexual harassment at work. In the last decade, over 20,000 accounts have been filed. Under the cases filed, majority of cases reported were from the female sex (Gai, 2009). In the year 2008, Louis Harris and Associates conducted a telephone poll on 782 workers of the United States. It came up with the statistics that 31 perc ent among female workers admitted to having reported sexual harassment at work. Only 7 percent of their male counterparts reported the same. A significant percentage of 62 percent of those targeted did not take any action. Out of the respondents, 100 percent female reported that the person harassing them was a man while 59 percent of men reported that their harasser was a woman. Subsequently, 41 percent of the male reported that their harasser was a fellow man. Additional statistics records that 43 percent of women who reported experienced harassment from the supervisor, 27 percent from senior employees, 19 percent workers of same level while 8 percent had faced harassment from junior employees (Boland 53). Combating sex harassment at work is a big challenge. This is necessitated by the fact that establishing its causes can be complex. These causes can be social, psychological or political. Owing to the fact that some work relationships such as acting in most cases turn out to be in timate and intense, establishing sexual harassment in such scenarios can be very complex. The other aspect is that in most instances, employees are required to depend on one another in order to maximize productivity. How this should go has no clear guidelines. Making the situation trickier is that some positions at work such as that of the supervisor involves working closely with your team for results to be achieved. However, being accustomed to these close working relations may create

The events leading to the Monroe Doctrine Essay Example for Free

The events leading to the Monroe Doctrine Essay After Napoleon Bonaparte was defeated and exiled, the old monarchies of Europe acted quickly to reassert their old power. They crushed the democratic rebellions and restored dethroned monarchs to their thrones. Rumor had it that they wanted to destroy the new Latin America republics and restore the lands to colonial rule by Spain. Britain did not want this to happen because the monopoly-free ports of the new Latin American republics were profitable so the British minister at that time, George Canning, suggested that the United States and Great Britain jointly declare the Americas off limits to the European powers. At that time, Russia was expanding its territory from Alaska down the west coast of the North American continent and the people in the United States was afraid that the Russians would cut the Americans off from its window to the Pacific Ocean. This, combined with the fact that the Americans were also profiting from the monopoly free ports of Latin America motivated the United States to make some kind of declaration. There was opposition to a joint declaration with Great Britain because they didnt want to be morally held back from acquiring Spanish lands in the Americas. John Quincy Adams correctly saw that even if the United States did not join Britain the British would still protect the ports so he advocated a declaration by the United States without the British. President Monroe announced to the world during his regular annual address to Congress that the era of colonization was over in the Americas and that the European powers were not to interfere in the new Latin American republics. Since Monroe said it, this doctrine was named after him. The Monroe Doctrine could be said to be a self-protection doctrine because the noncolonization part was mainly directed at the Russian who were expanding down the west coast and if they were stopped, the United States would be guaranteed access to the Pacific Ocean. The noninterference part was another way that the United States protected itself. If a European nation took control of any land in the Americas the United States would be in danger of invasions. The Monroe Doctrine was an isolationist document because it prevented the  interference of any European nation in the Americas. In the terms of the Monroe Doctrine, Monroe warned the European powers away from the western hemisphere and in return the United States wont interfere with the war between the Greeks and the Turks in Europe. In short, the United States said that if Europe wouldnt interfere with American affairs then the United States wouldnt interfere with European affairs. By rejecting the British hand in partnership, the United States also followed the policy of isolationism because they did not accept European help even though their military was no match for European armed forces.

Strategic flexibility in interpersonal relationships.

Strategic flexibility in interpersonal relationships. REFLECTIVE PAPER How many times have you heard someone say something like this: â€Å"he just doesnt understand me† or â€Å"there has been a breakdown in communications between us†? Lack of good communication between people is a constant problem. As the author, Richard, points out in the first chapter, â€Å"The Communication Process†, communication skills are crucial to both getting the best out of people and extricating oneself from difficult situations. Nowhere is this more evident than in the personal relationships we form with family and friends. The author introduces the idea of â€Å"Strategic Flexibility† (SF), which means that a person uses every communication tool he has in order to effectively get his point across in a given situation. SF is not limited to words but expands into a whole â€Å"communication repertoire† that can include gestures, expressions, body language and tone of voice. SF is characteristic of people who are successful not only in their professions but in their personal relationships as well. The authors description of SF has six steps: anticipate circumstances; assess the factors and conditions you find yourself in; evaluate the current situation in relation to your own abilities; select the most relevant communication skills you possess; apply the first 4 steps carefully; and reassess your communication after receiving feedback. Finally, creativity is also key to communicating effectively as it allows the speaker flexibility and adaptability. In applying this model to my own life, I began to consider some of my friendships and how they have either been strengthened or weakened because of a certain style of communication between us. Some years ago I had a friend I became quite close with very quickly called Julia. She was exuberant, funny and full of drama. We not only worked together but also went to bars together, out dancing, to comedy clubs and generally palled around. Hanging out with her was full of extreme ups and downs. At one point, Julia was having a great deal of trouble getting what she needed from her immediate supervisor, Rob. Rob and I were also friends. Julias frustration with Rob and Robs frustration with Julia was beginning to affect everyone else who worked with them. I offered to speak to Rob alone on Julias behalf, thinking that hearing some of her complaints and concerns from a third party might make Rob more receptive after all, he and I got along smoothly. I took Rob out for a drink and noticed immediately how uncomfortable he was. His body language said it all he found it hard to make eye contact, was hunched over in a corner of the table and smiled nervously from time to time. He really did not want to hear any of what I had to say. I had an idea in my head of the role I wanted to play with Rob. I planned to be firm and reasonable and to avoid raising my voice or showing anything but understanding that the dynamic between him and Julia was problematic. But I thought that I could help fix it if only I could get Rob to agree to have more regular and business-like meeting with Julia where they could discuss their issues and, with luck, sort them out effectively. But what wound up happening is that although I kept my voice even, all I did was put Rob on the defensive. I never really asked him for his side of the story and just assumed that everything Julia told me was the way things really were. I had arrived with this assumption because I knew others had occasionally found Rob difficult to communicate with. He could be a bit dry and sarcastic. But he was also very driven and good at his job, which was quite demanding in a number of ways. It did not occur to me to ask him how the pressures of his job and his frustra tions with Julias work style might be affecting the outcome of the department he headed. Needless to say, nothing came out of this meeting with Rob. As I spent more time around Julia, it became obvious to me that her way of dealing with problems was to give way to emotional outbursts rather than find a clam and thought-out way of telling people including Rob and, by then me what was troubling her. I myself made the mistake of confiding in Julia at a time when I was feeling very vulnerable and she wound up throwing back what I had told her in my face. I started to learn at that moment that being more careful about how and with whom I communicated with would have a direct effect on my happiness in both my work and personal life. The way to communicate with someone who tends towards being emotional is not to meet it with the same level of emotion but rather to step back and try to diffuse the situation by giving the person a chance to vent and then thinking before responding. This way, there is a better chance that ideas can flow peacefully between the parties. I am also much more receptive to body language now. If I was trying to speak to someone who was hunched over and not meeting my eyes, I would know immediately that the style of communication I was using was making the other person uncomfortable. Using the SF tools, I would try to be more mindful of the sender-receiver mode the author writes about. I did not receive messages properly or chose to ignore them, acting only as a sender. This one-sided communication style was probably the reason my attempt at peacemaker failed. My nonverbal communication was equally lacking. I could have made Rob more at ease by leaning back in my seat instead of leaning forward as if ready to attack. I could also have given him a reassuring tap on the arm or shoulder to indicate friendship and empathy. I did not listen to the indirect feedback Rob was giving me. I did not respond to his obvious discomfort nor did I really give him a fair hearing. I think choosing a bar was not a bad idea as it was a neutr al zone for both of us, but selecting a quieter bar than the one we went to also would have been a better choice, as it is hard to stay focused when people are playing pinball next to you! By ignoring Robs side of the situation and not doing much to make him feel he was not under attack, I also did not apply the ethical standards the author outlines, such as treating opposing views with respect. I do make a concerted effort to apply many of the standards of ethical communication in my relationships now. 2. Perception Self-perception, as well as perceiving the needs of others, plays a vital role in effective communication, an idea that is discussed at length in the second chapter, â€Å"Self, Perception and Communication.† The relationship between self-image and perception of both self and of others is immensely complicated. Low self-esteem can feed into other peoples perceptions of a person through signals in their body language, tone of voice and facial expressions. These in turn, can reinforce negative self-image when other people respond to the negative signals they are receiving and send them back again to the initial communicant. Stepping outside ones comfort zone by engaging in â€Å"risk-taking† can create a fundamental threat to self-identity. As the author points out, â€Å"to take that action, or have that experience, would so violate who you are that, should you do it, you would no longer be the same person. You would be forced to see yourself as someone different.† Yet this very act of questioning identity can be enormously empowering. I grew up a fairly withdrawn child. I did not relate well to my peer group and was always more comfortable around adults or animals. I was afraid of judgment, or being teased. My grandmother had me outfitted at an expensive department store twice a year, which just created a further separation between my peers, whose parents tended to shop at Sears and local shops on an as-needed basis and me. My clothing communicated that I thought I was better than everyone else even though that image could not have been further from the truth. The author points out that â€Å"Social comparisons are pivotal to self-evaluations. They depend less on objective circumstances than on how you judge yourself in relation to others on particular attributes.† This was certainly true of my school days. Because of my distance from and fear of my classmates, I retreated into the library during most recess periods. My bookish behavior again reinforced that I was different. The fact that I did not voluntarily engage with my classmates on the playground even though a big part of me wanted to made me even more of a target for teasing. In short, every method of communication I was using, from my clothing, haircut, behavior and choice of pastimes communicated that I was a snob, even though my self-esteem was shaky and all I really wanted was to fit in. As I grew up and realized the value of a certain level of conformity, my fortunes shifted. I started to dress in the same brand jeans as the cool girls, wore the same style of shoes and makeup and made sure my hair was cut in one of the latest fashion trends. These changes told my peers that I was becoming like them. They started to treat me as a friend. Even so, I always felt a need to stand apart from the pack, to be noticed. The solution turned out to be through acting. I took up theater classes, dance and singing and performed in school plays. By pretending to be someone else on stage, I could feed that need for to be someone different while still being one of the gang. I could take risks as another persona that I could not take in my real life. After many years, I am still learning how to read people better instead of assuming they think the worst of me automatically. I have found that it is important to try to read people, to try to understand their own self-perceptions and the way they view their environment. These observations act as the feedback mentioned in the SF description. In this way, I can better react to what people are actually saying to me (rather than acting out of irrational fears) and adjust my own body language, word choice, even my dress in order to establish a rapport. This becomes very important in interviews and work situations. I have had jobs where my employer was excellent at communication and somewhere the communication was lacking. In the case of the former, I once worked for a professor who was very good at giving me work that matched my level of competence but that also helped stretch my skills set. When he gave criticism, it was also in a gentle tone of voice. He used words that were not judgmental but instead focused on showing me how I could improve my work with a few adjustments or a change of direction. An important quality Jeff had was that he was also always willing to listen to my ideas, help me develop them and would give me credit for work that was uniquely mine. Jeff was a great example of someone who had the SF concepts down pat and used them every day in his dealings with staff. Jeffs method of communication was a pivotal experience in my work life. It helped build my sense of ability and encouraged me to think for myself. Because Jeff was such a supportive boss, I also worked harder to please him and took greater pride in producing quality work. I began to learn how to argue a point effectively, and without becoming emotional. I did this by consciously separating my ideas for the project at hand from things I had been told as a child. I forced myself to listen to criticism because it was given in a gentle and well-intentioned way. Jeffs style was one of the stepping-stones in transforming not only my perceptions about my own abilities but my ability to learn and grow in a job. 3. Listening Listening is also a skill upon which I have improved, even though this has required a good deal of effort. True listening means often having to force yourself not to react, at least not immediately. Listening requires more than simply hearing what another person is saying. It involves paying attention to the use of words, body language and expressions, and also trying to put yourself in the shoes of the person speaking. The more you make an effort to understand the perspective from which they are communicating, the more I feel you are truly listening. I have found this to be especially true with family. Often, there is a lot of emotional baggage we carry around from the things our parents and siblings said to us when we were very young, a point the author makes repeatedly. The author likens our self-perception to a map: â€Å"What this means for you is simply that your perception of reality is not reality itself, but it is your own version of it—your â€Å"maps.† But these maps are not necessarily complete pictures of who we are, or of who we are capable of becoming, just like a road map does not necessarily show every tree, brook and signpost on a route. You can always use a different map or a different route to get to the same, or even a different, place. Again, the idea of flexibility in the SF concepts applies, since taking a different road can make for a pleasanter journey. This also means, however, that no two people are working from exactly the same map. Listening is therefore crucial to being able to find your way along another persons route. Keeping in mind that the way one sees the world or a particular problem may not be the same as the person you are conversing with. Preconceived notions or â€Å"perceptual filters†, as the author refers to them, can keep people from actually listening to each other. It is therefore important to try to keep both the mind as well as the ears open in order to foster communication. Conversely, shared experiences, where they arise, can also cement relationships. My siblings and I share many of the same experiences but have very different perspectives about them. I have learned a good deal about who they are as people by listening to them expand their views, and it has also influenced how I now see myself in relationship to them and our parents. Only by taking the time to listen can you find those synergies wi th other people and develop healthy and productive communication.

Male Carica Crude Solvent Extracts

Male Carica Crude Solvent Extracts Male pawpaw tree have flowers that grow on short stalks (Chin et al., 2001). Carica papaya is a native of the tropics of America, perhaps from Southern Mixico and neighouring central American (Morton, 1987). According to Eno et al. (2000), pawpaw is the fruits, of the plant. Carica papaya belong to the genus carica. Preliminary qualitative and quantitative phytochemical analysis of ethanol and aqueous extracts of C. papaya showed the presence of many phytocompounds. These extracts were found to inhibit these eight test micro-organisms: Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella typhi, Escherichia coli, Aspergillus niger, Penicillium notatum, Fusarium solani and Candida albican.(Okoye, 2011). Proximate analysis of leaves of C. papaya also showed appreciable quantity of ash content, crude protein, crude fat, crude fibre, carbohydrate and high calorific value (Okoye et al., 2011). In this present work, the author intends to study the preliminary pharmaceutical constituent s of crude solvent extracts of flower and stalk of male Carica papaya since little or no work had been done in this area. The aim and objective of this work is to determined the phytocompounds present in flower and stalk of male Carica papaya; to extract the crude solvent extracts of the flower and stalk of male C. papaya and to find out whether the solvent extracts can inhibit the growth of ten pathogenic fungi. Carica papaya is composed of many biological active compounds, many of which are found concentrated in the latex, which is present in parts of the plant (Madrigal et al., 1980). Within Carica papaya plants, the concentration of bio-actives will vary with position of plant, age of plant and cutivar. Also, concentration of bioactive differs between male, hermaphrodite and female plants. Female plants exude more latex than hermaphrodite and male plants. Carica papaya latex is rich in cystein proteinases which are proteolytic enzymes (caricain, chymopapain, papain and glucylendopeptidase) these constitute 80% of latex enxymes. Other enzymes present are glycosyl hydrolases (à ¯Ã‚ Ã‚ ¢-1, 3-glucanases, chitiriases and lyzozynus) protease inhibitors (cystertin and ghtaminylcyclotrunsferces and lipases (Moussaoul et al., 2001). It was reported that intake of two table spoons of pulverized papaya seeds mixed with hot water twice per day is used in the traditional management of diabetes and obesity (Adeneye and Olagunju, 2009). Carica papaya (pawpaw) contains the enzyme papain, a protease used for tendering meat and other proteins (Morton, 1987). The fruits are popu larly used and processed into juice and wine, and also cooked as vegetable (Gragson, 2001). The seeds are medically important in the treatment of sickle cell disease and poisoning related disorder. The lead tea or extract had a reputation as a tumor destroyer agent. The flesh green tea is antiseptic while the brown dried leaves are best served as tonic and blood purifier (Ezugwu, 2008). Due to its antioxidant and fibre content, it is used in treatment of ailments such as chronic indigestion, overweighing, obesity, high blood pressure (Everetta, 2003). Sample Collection and Preparation Flower stalk of male Carica papaya was collected from Adazi-enu in Anaochia Local Government Area of Anambra State, Nigeria. It was dried under air and mild sun-shine, for about three weeks and ground into powders. The ground sample was then kept in a clean polyethylene bottle until needed for analysis. Phytochemical and the extraction of the active components are determined by the methods outlined by Harbon (Harbon, 1973). The antifungal activity of flower and stalk of male C. papaya was determined by agar well diffusion method (Okeke et al., 2001). The zone of inhibition was recorded to the nearest size in mm (Norrel, 1997). After extraction of the active components using three different solvents separately (Ethanol, Water and N-hexane), the solvent extracts were evaporated to dryness at about 67, 98 and 66 °C respectively in a water bath separately. 1, 2, 3, 4 and 5mg of dry ethanolic, n-hexane and water extracts were weighed into five different labeled test tubes differently. T hen 10ml of the corresponding solvents used for extraction was added to the dried extracts to make 0.1,0.2,0.3,0.4 and 0.5mg/ml concentrations of the extracts. The MIC of flower and stalk of male Carica papaya were found out by using 0.1, 0.2, 0.3, 0.4, and 0.5mg/ml of each extract which were added to test tubes containing 1ml of sterile medium. The tubes were then inoculated with a drop of microbial suspension and incubated for 48 hours at 25 °C. Then 0.1, 0.2, 0.3, 0.4, and 0.5mg/ml of amphotericin B (for A. flavus, F. verticilloides, A. parasiticus, F. oxysporum and Fluconazole (for all candida was used for positive control and water for negative control respectively. The MIC value was determined, macroscopically after incubation in comparison with the growth and sterility control. MFC; the plates (petri-dishes) were divided into six different sections and labeled with the different concentration on the base of the plates, these were used to plate out the contents of each tube with the respective sections of the plate.

The phytochemical constituents of the flower and stalk are as follows: alkaloids 0.53  ± 0.01%, floaonoid 0.08  ± 0.02% saponins 0.37  ± 0.02% tannins 2.06  ± 0.01%, terpenoid 0.02  ± 0.01%, steroids 0.08  ± 0.01, phenol nil, cardiac glycoside 1.87  ± 0.02%. The flower and stalk of male Carica papaya contain an appreciable quantity of alkaloids. It could be used to remedy some diseases, depending on the type of alkaloids it contains. The presence of alkaloids signified the possession of medicinal values within the flower and stalk. Pure isolated alkaloids are used as basic medicinal agents and fungicidal properties. The presence of steroids in the sample indicates that it could be used to decrease the presence of cholesterol in the bloodstream. Saponins have been used in the treatment of cardiovascular disorders, they facilitate and ea se the process of digestion and encourage the growth of beneficial bacteria within the intestine. Saponins also contribute to health and efficiency of the immune system by binding to germs and other pathogens as they enter the body. In this sense they function as natural anti-bodies. They are found to be antimicrobial and are particularly effective when used to treat yeast a infections. The presence of cardiac glycosides in the flower and stalk of male Carica papaya indicates that it could be used, in the treatment of congestive heart failure and cardiac arrhythmia. Table 3 portrayed the result of antifungal activities of three solvent extracts of the flower and stalk of male Carica papaya on ten micro-organisms (fungi) investigated in this work. They are: A. niger, M. gyspseum, C. albican, A. flavus, F. verticilloides, A. paraciticus, F. oxysporum, C. glabrata, C parasilosis and C. tropicalis. Five different concentrations of aqueous, ethanolic, and normal hexane extracts were used. At 0.1-0.5mg/ml concentration, aqueous extract showed some inhibitory effect on eight out of the ten test fungi. The fungi are; A niger, M. gypseum, C. albican, A flavus, C. parasilosis, A. parasiticus, C. glabrata and C. tropicalis. No action was recorded on the two remaining test fungi: F. verticilloides and F. oxysporum. At 0.1-0.2mg/ml concentration, ethanol extract shows some inhibitory effect on seven out of the ten test fungi. These are: A, niger, M. gypseum, C. albican, A. flavus, C. glabrata, C. parasilosis and C. tropicalis. At 0.1-0.2mg/ml, ethanolic extr act shows no action against three fungi. These are; F. verticilloides, A. parasiticus, and F. oxysporum. At 0.1-0.5mg/ml, n-hexane extract indicated some inhibitory effect on six out of the ten test fungi. These are: A, niger, C. albican, A. parasiticus, C. glabrata, C. parasilosis and C. tropicalis. It had no action on four fungi. These are: M. gypseum, A. flavus, F. verticilloides and F. oxysporum.. Table 3 also showed the commercial drugs used as positive and negative control. Positive control using two different antibiotics specifically showed remarkable inhibitory effects on the ten test fungi while the negative control showed no action against the ten test fungi. Table 4 showed the results of the minimum inhibitory concentration (MIC) of the aqueous, ethanolic and n-hexane extracts of flower and stalk of male Carica papaya on the ten test fungi. The least MIC of the aqueous extract 0.05  ± 0.01mg/ml was shown on five test fungi: These are A. niger, A. parasiticus, C. glabrata, C. parasilosis and C. tropicalis. MIC of the ethanolic extract 0.05  ± 0.0lmg/ml was shown on four test fungi. These are, C. albican, A. flavus, C. glabrata, and C. parasilosis. MIC of the n-hexane extract 0.05  ± 0.0lmg/ml was shown on five test fungi. These are: C. albican, A. parasiticus, C. glabrata, C. parasilosis and C. tropicalis. Table 5 showed the result of minimum fungicidal concentration (MFC) of the aqueous, ethanolic and n-hexane extract of flower and stalk of male Carica papaya on ten test fungi. For aqueous extract, the least MFC 0.2  ± 0.01mg/ml was shown on one test fungi,Candida albican. For ethanolic extract, the MFC 0.02  ± 0.0lmg/ml was shown on one test fungi Candida albican. For n-hexane extract the least MFC 0.02  ± 0.01mg/rnl was shown on one test fungi: Candida glabrata. Conclusion The analytical investigation showed that, the crude solvent extracts of flower and stalk of male Carica papaya have antigfungal effect on these microorganisms; Aspergillus niger, Microsporum gypseum Candida albican, Aspergillus flavus, Aspergillus parasiticus, Candida glabrata, Candida parasilosis and Candida tropicalis. This implies that crude solvent extracts of flower and stalk of male Carica papaya can be used to cure the diseases caused by the above mentioned microorganisms. Bioactive ingredients responsible for the antimicrobial properties of the flower and stalk of male C. papaya should be elucidated.         Ã‚   Male C. papaya Plant Flower and Stalk of male Carica papaya References 1.Okoye, E.I., Orakwue, F.C. and Ebeledike, A.O.
