Auditory System

The world contains all kinds of energy that translates into information about what we see, hear, smell, touch and taste. A sensory system is a part of the nervous system responsible for processing specific sensory information. The components of a sensory system include sensory receptors, neural pathways, and parts of the brain involved in sensory perception. To begin, energy from the environment stimulates the receptor cells in whichever sense organ is being used. If this information were auditory, the ear would convert sound waves in the air into electrical impulses that would further be interpreted by the brain as sound.A sound wave first enters the pinna, the fleshy part of the ear on the outside of the body. It then travels through the external auditory canal where it then meets the eardrum, a thin membrane in the outer ear. The eardrum then vibrates in response to the sound wave. What we hear will depend on the wavelength and frequency of the wave. The eardrum is connected to a group of three small bones call â€Å"the ossicles† in the middle ear. This group includes the malleus, incus and the stapes. These three bones, the smallest in the human body, protect the eardrum from more intense sounds and also deliver the vibrations to the base of the stapes.The stapes then sends the vibrations into the inner ear and interacts with the round window. The round window, a small membrane that allows liquid inside the inner ear to be displaced and receive the vibration. The vibration travels through the spiral structure of the inner ear called the cochlea and ends at the round window. Inside the cochlea there are three canals: the scala vestibuli, the scala media and the scala tympani. The scala vestibule leads up to the apex of the cochlea, the scala tympani leads down to the round window and the scala media sits in between the other two canals.All of these canals are filled with fluid and are separated by two different membranes; Reissner’s membrane a nd the Basilar membrane. Both of these membranes are flexible and respond to the vibrations traveling through the scala vestibuli. The movements of the membranes then send the vibrations down the scala tympani. A structure called the Organ of Corti, which is situated on the basilar membrane, becomes stimulated as the membrane vibrates and sends nerve impulses to the brain. Within the Organ of Corti are a group of specialized cells called hair cells, which are covered by the tectorial membrane.As the basilar membrane vibrates, the hair cells are bents and push up against the tectorial membrane. This causes the hair cells to fire and send nerve impulses to the auditory cortex on each of the brains hemispheres through the cochlear nerve. How we determine pitch can be explained with two different theories. The Place Theory states that the entire basilar membrane does not vibrate at once so different parts of the basilar membrane respond to different frequencies of sound. Lower frequency sounds vibrate the basilar membrane near the apex of the cochlea while higher frequency sounds produce vibrations closer to the base.The Frequency Theory states that the frequency of firing matches the frequency of the sound wave. Hearing loss can occur for a number of reasons. Damage to the eardrum due to age and prolonged exposure to loud noise may cause the hairs or nerve cells in the cochlea to wear out and become less effective. A buildup of earwax can block the ear canal and prevent of sound waves from entering the eardrum. Otosclerosis, a genetic form of hearing loss in which the stapes is fixed in place so sound cannot enter the inner ear.

Mesoamerican civilization

In the civilization of the North and South America people, farming started later than the Afroeurasian. But the American civilization started on its own as opposed to the dependence of lending and borrowing of ideas from one community as was witnessed in the Afroeurasian civilization.The argument about the Mesoamerican civilization has been as a result of single culture (known as ‘mother culture’), while others claim that it was through learning and copying from others that the civilization developed, i.e. ‘sister culture’. The civilization arguments has to a larger extend been linked to the Olmec influence.   This is because the Olmec has been considered as the earliest civilization groups in the Mesoamerica.Hence some of its earliest civilization practices can only be found within the heartland of Olmec while others are beyond the heartland of Olmec. Some of the artifacts that are only found in the heartland of Olmec include colosal heads, earthen platfo rm and monolith alters.   There have also been cases where other Olmec style artifacts have been found in other different areas.There are objects that have been considered to be of Olmec – traditions in areas that are out side the heartland of Olmec appearing together with the traditional objects of that place.   For instance, at Las Socas, objects created in local tradition contain Olmec iconography (Reilly, p 371).This indicates that the traditional of Olmec was flowing from the Olmec heartland towards other areas and not vice versa.   In this case the argument of Olmec to be of the â€Å"mother culture† arises.   Michael D Doe is one of the proponents who argue that the Olmecs had a mother culture. â€Å"There is now little doubt that all later civilization †¦ whether Mexican or Maya, ultimately rest on an Olmec base,† (Coe, 2002, pp 62).Those advocating for ‘sister culture’ feel that the Olmec civilization took place simultaneously with the other places.   The argument is based on the fact that Olmec was only among the earliest equal civilizers.   Flannery and Marcus have agued that it is only through competitive interactive that civilization can take place.   â€Å"It is adoptive autonomy and frequ3ent competitive interaction of such chiefdoms that speed up evolution and eventually make useful technologies and sociopolitical strategic available to all regions†, (Flannery & Marcus, 2000. pp. 33).Therefore, looking at both the arguments of the mother culture and sister culture, it is not right to agree that the Olmecs civilization was a mother culture.   For instance, according to Pool (N.d),The Olmecs of San Lorenzo were only a handful of societies in the Americas that had achieved comparable degree of social and political integration by the end of the second millennium B.C. On the other hand, sociopolitical complexity varied among Olmec societies within the Gulf coast region, the intensity and effects of interaction with the Olmecs varied across Mesoamerica, and other Formative societies made significant contribution to the developemtn of a distinctively Mesoamerica civilization tradition, (Pp 2).The use of the term formative (preclassic) was developed by Gordon Wiley and & Philip Philips (1955, 1958), â€Å"Where it indicated the village agricultural threshold and/or sedentary life†¦Ã¢â‚¬  (Pool, Pp.8).The formative period has various prehispanic historical changes taking place.   Before 200 B.C. most of the inhabitants lived in small bands that were characterized by several mobility and their main activity being hunting and gathering.   Then came the development of a lot of urban centers by 300 A.D.   These urban centers came about because with time, the mobility was reduced and the group settled into larger groups and thus staying at one place for longer period than before.The increased settlement was influenced by the fact that people have increased domes tication of crops and had also indicated the storage facilities.   â€Å"In the initial formative period (2000-2500 B.C.)†¦The processes of domestication and sedentarization combined to foster the spread of settled farming villages over much of the area that was becoming Mesoamerica,† (Pool, pp.8).The early societies of America shared the hunting and gathering activities with the other societies across the boarders.   These behaviors changed among the communities, as they become more settled and avoided movements.   This lead to the emergence of social hierarchies, centralized governments, and various religious concepts.   Their neighbours adopted the practices that emerged from one culture to another, including the OlmecsLike all other complex societies of the America, the Olmecs also depended on this hunting & gathering, domestication of food and animal as well as fishing for their daily needs.   These activities enabled them to build strong social and politi cal hierarchies that integrated many other small communities.Mesoamerican ReligionIn pre classical periods of the Mesoamerican people religion developed due to the influence of the seasonal cycles, â€Å"In their world –view, the development of the corn plant was one of the principle archetypes.   Another intrinsically tied to the former was the archetype of the alternating powers of fire and water, derived from the division of the year into two seasons, then dry and rainy seasons†, (Obafemi & Olupona, 2004, Pp 199).The Mayan community of the Mesoamerica developed their religion because of the belief that there was a relationship that existed between the human being and the supernatural power.   They nurtured and developed this belief to the extend of giving human sacrifices to the gods.   High priests of the Mayan religion performed the human sacrifices.   The key aspect of this religion was the great importance it gave to the agriculture and the time timeless of the harvests. â€Å"The Mayan religious calendar Ezolkin comprised of only 200 days and two cycles each comprises of weeks spanning 30 days and 20 days.   Another calendar called tun comprised of 360 days and five added unlucky days†The Mayan believed in the cycles of rails and to the harvest of the produce.   They considered the agriculture product to be a gift from God.   To the Mayans, human beings were supposed to be attuned to the cyclical changes so that they can obtain more benefits from them.The offering of sacrifices, of both human and animal was meant to appease the gods.   Songs and dances as well as competitions accompanied the sacrifices.   There was no separation of civil and religious life. Therefore, the kings acted as both rulers and principal intermediaries between human beings and gods. The other reason that was behind sacrifices was that, many gods needed human support which if was not forthcoming; they may weaken and eventually die.Life afte r death was determined by the position that a person held before the demise. Therefore if a person held a high status position on earth, that position will still be held even after death. While those with lower positions held again the same positions.About the universe, the Mayas believed that the universe would continue to be created and destroyed continuously.   The cycle for the destruction would be taking place after a period of about 5000 years.   The destruction and creation would be the exact duplicate of the previous one.   They perceived the earth to be the back of the giant caiman that was floating in the pool, with the exposed part being flat with four comers.   Above the earth, was the human with 13 levels (7 going up, and 6 going down), (http://encarta.msn.com/encyclopedia_761580499_2/Pre-Columbian_Religions.html). This was of the same oscillation as the rising setting of the sun.The Maya gods and goddesses formed a family (pantheon), each having four color aspe cts.   The religious followers believed in deities in heaven, but also having counterparts on earth and vice versa.   The deities also comprised of counterparts of the opposite sex.   â€Å"For example the supreme celestial god Itzama, the aged patron of culture and learning.   Kinich Ahau, the sun god, may have been a youthful aspect of Itzama in addition to being his son†, (http://encarta.msn.com/encyclopedia_761580499_2/Pre-Columbian_Religions.html).Like the Mayan, the Aztec believed in the destruction and creation of the universe, but that had multiple differences. They believed to be living in the fifth and final universe, which they considered to be the fifth sun. In this case, they believed that there would be no sixth universe after the fifth destruction, and that there was escape or avoiding of this destruction but it could only have been delayed. The sun was considered to be a warrior that fought a continuous unending war against darkness. Therefore, as long as the sun was still fighting, the fifth universe could not be destroyed. To make sure that the sun continued with the fights, they offered blood it through sacrifices. The sacrifices were especially of human who were war captives.Befitting their central role as allies of the sun, the Aztecs thought they lived at the center of the universe. Their earth was divided into four quadrants, each with typical Mesoamerica color-direction symbolism, though the specific pairings of colors and directions were different from those of the Mayas. The four quarters met at the main temple (Templo Mayor) of Tenochtitlan the Aztec capital. This temple was also the point where supernatural forces from the heavens and the underworld came together. The heavens were composed of 13 ascending levels. The sun, the moon, the planets, and the stars traveled through the lower levels. The upper levels were the homes of winds, storms, colors, and remote gods. The underworld contained 9 levels, all descending, u npleasant, and dangerous, (http://www.angelfire.com/realm/shades/nativeamericans/precolumbionrel4.htm).The pantheon of the gods and goddesses of the Aztec were more complex and performing different overlapping functions at different ceremonial functions. The gods were related to different practices. For instance, the Tlaloc was the rain god. There were also the gods that were related to the agricultural produce and deities related to fertility.BibliographyCoe, M.D (2002): Mexico: from the Olmecs to the Aztecs, London, Thames and Hudson.Flannery, K. & Marcus, J.

They had launched this service in 2007 and it had a relative advantage of offering a comprehensive genome scan and analysis online. However,  this online service was discontinued in 2007 giving 23andMe the relative advantage of continuing its online genome testing service in a more cost-effective manner.  

This is International Management Essay Example | Topics and Well Written Essays - 500 words

This is International Management - Essay Example Emergence of economies like India and China that offer skilled labor at comparatively cheaper rates has led to business organizations relocating business units like back office operations to these nations where they can get the desired quality level at cheap rates. In addition to this firms have also been using international expansion to reach out to new and potential markets. The restriction of trade barriers has also made investments in overseas destinations easier for firms. Examples of firms pursuing international strategies include Lenovo Computers, Wal-Mart and others that have successfully entered into new markets and established a formidable foothold in those markets. International expansion strategy is recommended in circumstances where domestic markets for an organization starts getting saturated and the company has enough internal resources and expertise to manage business in an international level by being able to sustain its core competence areas in new foreign markets. It should also have sufficient financial resources to sustain the business in foreign locations. Favorable government regulations and a congenial political, economic, sociological environment are also essential pre requisites for a firm to enter into a foreign market (Organization for Economic Co-operation and Development, 2007, p.24-38). Regionalization Contrary to globalization regionalization involves an entirely different perspective in which firms restrict themselves to specific regions and confine their businesses to those regions and devote their focus solely towards a particular region.

Antibiotic Resistance of Bacteria Research Paper

Antibiotic Resistance of Bacteria - Research Paper Example This can partly be attributed to the fact that microbes and bacteria which spread the infections are quite flexible in nature and have a great tendency to resist the effect of antibiotics. Another factor that has increased the resistance of microbes and bacteria against the antibiotics is the increased use of antibiotics. 12500 tons of antibiotics were prescribed in the US in the year 1998. More than 60 percent of the use of antibiotics in the US can be attributed to the agricultural practices resulting in an increase of 18000 tons of antibiotic use yearly (Todar, 2009). These days, almost 70 percent of the infection-causing bacteria are able to resist some common antibiotic drug. Antibiotics were found originally as a result of an experiment conducted in 1928 by Alexander Fleming. In the 1940s, the findings generated by this experiment were employed for mass-production of penicillin using the Penicillium notatum as a mold. Strains resistance of bacteria were started to be found in t he late 1940s. As of today, over 70 percent bacteria which are responsible for the spread of the hospital-based infections resist at least one antibiotic. There are myriad of reasons for the continued spread of the antibiotic resistance. These reasons include but are not limited to the excessive recommendation of the antibiotics’ by the doctors, retarded compliance of the patients with the prescribed treatments, employment of the antibiotics as growth drivers in the animals, insufficient hygiene of the hospital environment and enhanced international voyage. There are two fundamental ways in which the resistance of bacteria can be improved. The first way is by employing a built-in feature that facilitates the exchange of resistance genes among the bacterial DNA. The second way is by mutation. Antibiotics kill the cells of the bacteria by causing a distortion in the critical function. â€Å"This is achieved in the cell in much the same way that a saboteur can cause a massive j etliner to crash by simply cutting the hydraulic lines† (Purdom, 2007). Antibiotic resistance of bacteria works only by causing a disruption in the functional systems. Evolution of the bacteria into man needs strengthening of these systems. It becomes difficult for the antibiotic to link with the altered protein when the bacteria â€Å"have a mutation in the DNA which codes for one of those proteins† (Purdom, 2007). Public health is exposed to a lot of threats with the increase in antimicrobial resistance because it declines the efficiency of the antimicrobial treatment and increases the mortality rate, morbidity and the cost of healthcare in the long run. The mortality rate jumped from 0.2 percent to 3.4 per cent upon the outbreak of resistant Salmonella spp. Strains. â€Å"In 1995 the cost of containing an outbreak of infection caused by methicillin-resistant S. aureus in a district general hospital in the United Kingdom was estimated to exceed US$ 560 000†¦whil e the annual health care cost associated with the treatment of resistant infections in the USA was estimated at over US$ 4 billion† (Smith and Coast, 2002, p. 126).

Homeland Security - Predaredness & Prevention Assignment - 3

Homeland Security - Predaredness & Prevention - Assignment Example The model includes some of the most important steps which could be taken during emergency. The need of management for emergency circumstances is now evolving in almost every state of the world as terrorist activities have been noted to increase with extreme socio-political movements around the world. The need of the preparedness and prevention is thus important because threats can considerably cause devastation of infrastructures. One example of devastation could be taken from the attacks of 9/11 in 2001. The need of the preparedness and prevention model is due to the fact that people needs to have awareness and training regarding how to counter terrorist threats. Moreover, there are some of the preparedness plans and models for prevention of terrorist attacks which are already in action. One of the most widely used and effective preparedness and prevention plan is by National Incident Management System (NIMS) (Federal Emergency Management Agency, 2004). Devastating incidents which could not be controlled by agencies separately might be solved by interrelated patterns joi ned together by different agencies. National Incident Management System is basically allowing the agencies to interface and work together to mitigate the threat, survey vulnerability and prevent the dangers of threat (Federal Emergency Management Agency, 2004). The first and foremost step in the plan of preparedness and prevention is that assets of the organization are identified. Assets could include any material or structure which could be regarded as beneficial and valued to the company. Identification of assets could be done on the basis of prioritizing the organizational structures and belongings. In case of varied and large amount of assets, it is suggested that assess are characterized in terms of its value. Categorization is the most helpful way to identify assets as noted in other preparedness and

They are expressive and emotional; yet they have some hypnotic features which make people think about the sense of their being in the world. It seems that some dancers almost do not move; however, one needs to understand that static poses are sometimes more difficult that dynamic movements.  The costumers, music, lighting and decorations support each performance and create necessary settings where choreography of the dance can be understood by spectators.

Organizational Change through Leadership- Electronic Healthcare Assignment

Organizational Change through Leadership- Electronic Healthcare Records Implementation - Assignment Example The implementation of the Electronic Health Record System was the proposed change in the organization. The change was expected to improve the healthcare center problems and contribute to its growth and development (Overhage, Evans and Marchibroda, 2005). b. Methods or processes employed Many methods were employed in identifying the problem. Firstly, the hospital experienced a significant delay in providing patients’ information on time especially with large numbers of patients. The delay in registering patients and issuing of relevant documents contributed to a delay in the provision of medical services the resulted into loss of many lives. Secondly, the hospital offices were extremely small to accommodate large volumes of files containing each patient’s, doctors, and other staff information. The organization management had to come up with a computerized method of record keeping to get rid of manual files. Thirdly, the high competition in the healthcare industry forces healthcare centers to adopt the most recent technology in order to attract more customers. Most people prefer healthcare centers that are fully equipped electronically and technologically because they stand a better chance of dealing with all types of sicknesses. c. Significance of the problem The implementation of Electronic Health Records System (EHRS) will bring about a lot of progress in the health sector. The program will lead to the advancement in the health center by introducing an efficient and reliable record keeping method. Health Information Technology systems make use of the data required in the improvement and protection of population health by the policy makers, physicians, and health service users. Presence of relevant technology on human and health services assists the both affected and infected people in many ways and saves them both time and money (Health & Development Information Team, 2005). EHRS will also contribute a lot in the health sector whereby an individu al can easily take his or her medical records by the bedside. In addition, the implementation of EHRS will also enable physicians diagnose various diseases comfortably since they just ask questions and input data in the computer after which, they easily do the analysis. 2. State the need for and rationale for change   Literature/evidence supporting change According to Institute of Medicine (2000), health information technology has a lot of significance in the healthcare industry through improving delivery of healthcare services. Health Information Technology plays a significant role in implementing changes within the healthcare industry using many processes. In the past, healthcare services in United States were prone to a lot of errors, poor quality services, and lacked consumer confidence (Berner, Detmer and Simborg, 2005). The implementation of EHRS will assist in eliminating the above problems and making the healthcare industry more technologically advanced. Moreover, the need for change among many organizations is driven by the high rate of globalization and information technology advancement (Eason, 1988). On the other hand, the manual process of keeping health records is cumbersome and time consuming. Healthcare centers using manual means of keeping records have a problem marinating their customers and staff (Ingram & Lavery, 2009). The main aim of utilizing technology is making work easier and saving time to do work. Software manufacturers are competent enough to

Articles 81 and 82 of the European Community Treaty prohibiting cartels and other "concerted practices" distorting competition along with prohibiting the willful acquisition or maintenance of monopoly power are similar to Sections 1 and 2 of the Sherman Act outlawing concerted action to restrain trade. Consider, for example, the proposed merger of General Electric and Honeywell International Inc., two U.S.-based corporations, which was blocked by the European Union in 2001 even though U.S. antitrust regulators had already approved the deal. Jack Welch, then CEO of General Electric, complained that "European regulators' demands exceeded anything I or our European advisers imagined and differed sharply from antitrust counterparts in the U.S. and Canada." an order designed to pressure broadcasters into getting DTV signals on the air--or, at least, to "remind licensees of the importance of their DTV construction efforts," the FCC has ordered a series of sanctions for broadcasters that miss their DTV deadlines without good excuses. The order matches the

The Effects of the Rise of Regional Languages and Solution Essay

The Effects of the Rise of Regional Languages and Solution - Essay Example For instance, the worldwide use of English in business, political and diplomatic transactions has seen its gradual rise to an international status and thereby guaranteed its existence and survival in the coming years; it is projected that by the year 2050, over a half of the world’s population will be adept in it. Unlike the English language and other regional languages, native languages are limited to and within particular societies, with limited usage among small groups of people in those societies. The imminent threat of extinction of native languages has caused many adverse effects to societies and the speakers of these languages all over the world. As the basis of civilization, native languages are the cornerstones of cultures; they have a massive impact on civilization in societies. For example, ancient Muslim scholars developed some of the ancient Greek science after translating the knowledge written in Greek into the Arabica. As a result, the translated knowledge helped other civilizations to develop and spread the knowledge; therefore, language provides the road map for cultures, tracing the origins of people and guiding them into the future. However, some languages have died; some are about to die, or will die due to social, economic, political and technological reasons. Inferences can thus be drawn that, the death of a language  equals to  the death of civilization because language is the first stage of civilization (Grimes, 2002). It is undeniably true that not a single language in the world is autonomously sufficient in itself to capture and adequately express all ideas and information effectively and efficiently; this brings us to the importance of having many languages  in the world (Ostler, 2000), which is because of the existence of native languages. These native languages have amassed volumes of information and knowledge about all the subjects in the world; for instance, every native language has developed its

International Law In Business Dispute Essay Example for Free

International Law In Business Dispute Essay With the diversity in the exchange of business portfolio continues to grow, a rational legal device should help to solve the various conflicts that arise in various international business conflicts developing from such business transactions. The international business and trade are basic pillars for the growth and economic sovereignty of the global states. The compliment of comparative and absolute advantages will constantly remain upraised. Hence therefore, the global states will remain morally upright in exchanging commercial activities and products from one state to another.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Like any other activity operating within social dimensions, business activities are partied with various conflicts. However, with the rationality ascribed to the conflict theory working within social structures, the same is critical in providing standards of social changes and revolutions. Perhaps, without conflicts within business structures, the same cannot strike a step ahead in horror of growth and development. However, the same business conflict is impartial in preventing adequacy of cohesion in international business standards. With the counterfeit results of international business conflict, a rational analyst would be indifferent of the role played by the international business in the same. Therefore, one would perhaps ask, does international law provide an environment for settling business disputes? If yes, what are codes of its dimensions? However, the logics to this thesis statement would call for sublime academic research for a scholar who would not compromise the authenticity and valid support of a research work.[1]   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The international businesses and trade operates within the international environment, business structures, parties into business contracts and legal and priority requirement into international business contracts. With the diversity into the activities found beyond the national business borders, then the foundations of these transactions is ratified by the activity of persons founded on diversity in racial backgrounds, ethnicity, domestic constitutions and commercial laws, above other fundamental human basics.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   However, these differences should be brought together in a common understanding in the person’s within the contractual authorities of international definitions. Perhaps however, international law brings comfort to the international business family providing a support for general cohesion and exchange of activities across the national borders. Throughout its mission, the law provides tools of support for the activities and structures operating within the general framework of the international business. In a short hand, a rational being may purport this as the positive contribution of the international law in settling business disputes. However, the same law is deemed as a basic support for increased international chaos and disputes. On grounds of rationality, this is the negative impact of internal law in settling business disputes.[2] For impartiality in both of the phenomena, stakeholder into their detailed description should never be compromised. Advantages of international law.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Summarily, one can say that international law does to business what Aristotle did for the school of philosophy. The domain of the international law contribution to business would perhaps open volumes of discussion if taken at a deep emphasis. However, a sub detailed analysis would still provide a support for the same.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Within the international business, an encapsulation of activities of intensified nature is the operational attire of the system. These activities are compounded by diversity in their attributes and volume of work. It involves transactions of broad nature brought forward by nationals of different human understanding. Due to the diversity in these activities and domestic legal authorities, parties into these activities often find themselves trapped in the pool of conflict between one another, structures and activities. For harmony into the business activities, international business comes to provide understanding and harmony into such business prospects.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Firstly, the environment, within the international business activity ought to be taken care off. Various production, distribution and business transaction processes involve dimensions that are threat to the environment. The global environment has continued to suffer degradation due to various commercial activities such as factory exhaustions and productions, the maritime activities like oil spillage, over exploitation of resources by the investors, general product dumping above others. The global environment is the most fundamental factor which defines the rationality for livelihood within the globe. Its degradation fosters a threat to the broad image of humanity. However, international law comes in to provide refuge for the global environment through various environment laws such as, the international marine laws, aviation laws, and commercial laws above others.[3] The package of the national laws is inadequate and perhaps is radically inefficient to factor in the responsibility of international environmental attributes.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Elsewhere, the international business involves various contractual relationship based on international foundations. Due to the generality of business environment, a breach into the contracts has been discretionary the fundamental daily concept. Such breaches would be impersonalized and irrational if promulgated under the imagery of the national business law. However, international business does coherent validation in breached contractual relationships of an international capacity. Through the codes and regulations of its various internal laws such as the international arbitration, such conflicts are brought down into formal spheres of logical formalities. It therefore seeks to invite legal modalities that govern the transactional portfolio of international contracts.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Indeed, a broad package of instruments is waived in the international business activities. The validation of there transaction would be limited by the legal requirements of commercial activities at the national imagery. Various instruments are required in the due execution of international business activities. Generally, the diversity into the transactions also provides a task force for diversity into the negotiable and activity transfer between different parties. The rationality in the administration, creation, transfer and the use of international business instruments is provided by the formalities of the internation business law. This will radically help to provide pursuit of harmony to those involved in transfer of business process.[4]   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   At the international parameter, consumer sovereignty and protection is never compromised. The law has provided that, products and processes within the dimension of business law should articulate standards with which sovereignty and the general health and purchase price support to the consumers should remain a priority. Elsewhere, it has never compromised support in maintenance of high standards of products, services and processes that are not harmful for human consumptions. Indeed, the GATT law stands to provide refuge on commodity dumping and maintenance of high quality products.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The international business operates within organizational structures. These may include aviation (both air and marine), factory stands, resource depots, banks, the legal bodies, above others. The proficiency should be maintained which is adequately catered for by the international law.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Broadly therefore, international law is compounded by various advantages with which the success and promotion of the international business is fostered Disadvantages of international law.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Though coupled with various advantages, the same is not limited to a number of weaknesses. Conventionally, international business acts within the broad structures of the international business portfolio. However, this environment captures person’s of different nationalities with limited scales of common understanding. A collaboration between these persons in however hypocritical and only limited to the attributes with which the parties may be willing to understand one another.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Consequently, international law has been the main source of global misunderstanding and the major pivot concept that provide a tool for interstate conflicts. Different parties and state into international business have echoed on various disputes and conflict whose raw synthesis is potentially rooted in the understanding of the international law.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Domestically, the business activities are safeguarded by the domestic commercial laws. However, such laws are only limited to the economic structures found within the spectral national boundaries. With the diversity into the economic empowerment of the different global states, their national law stands to be different in an adaptation of the structures operating within them. The economic authorities of different state activities validate them to operate in within different state activities and within different commercial laws. Elsewhere, the general difference in the economic dignity of different states imposes chaotic relations when a balance of understanding is employed to resolve international business activities.[5] The rational beings have never been at ease to compel at in providing a solitary understanding between business conflicts born between parties or states of different economic orientations. Summarily therefore, international law has been a basic source of misunderstanding and chaotic asymmetries between different nationalities.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Conventionally, international law stands to be a basic source of various global conflicts. Many people have ascended to this law as being a chief source of benefits at the expense of the others. Either, the same has being seen as a source of success to the highly developed and economically potential nations. The less developed and poor nations have however been seen as objects of exploitation by these laws. This is the foundations into the state of global conflicts and misunderstanding.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Broadly, different statues of the international laws have applied different in the domain of international business. Firstly, the labor laws provide a descent support on employment and personal protections at the workplace. These laws have been developing to provide material support that governs the rules and regulation for the international labor supply. The same has been developed via a coherent support with which the role of the workforce is to be given a support. Labor laws have been used to provide protection in terms of salary and wage payment so that workers are not exploited of the labor resource against wage package that does not provide for their sovereignty and high living standards. Either, it seeks to protect persons from effects of poor working conditions. Generally, international labor law is a package of administrative laws that provide adequacy in the working conditions of the people at their workplace. It also governs the international exchange of labor force. Consequently, it provides a support for equality in employment opportunities without discrimination into the grounds of  Ã‚   ethnicity, gender, nationality, race, religion and other parameter. It also encapsulates the avoidance of juveniles and young people from labor exploitations. Summarily, this law package provides a tool for a coordinated approach in the framework of labor within the international image.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Either, the sovereignty of holders of intellectual property rights and the role of internet has been of a great value indeed. The development of product and service has fundamentally been seen as an important factor if the state of international business is to be rationalized. Though the scope of intellectual property rights is too broad, a short hand summary of the concerned remains objective. The international law has however not overlooked the role played by the intellectual property ownership.[6] Indeed, various laws have been instituted which seek to govern the sovereignty in the rights of the intellectual property holders. Perhaps, the Blockbuster should never be down looked in defining the role played by the internet system in providing a support for sovereignty into the holders of these rights. The international law recognizes and appreciates the roles played by these holders towards the success of the global productions. The various laws instituted provide frontiers for continued support into the use and ownership of these rights to avoid the basic conflict which may arise thereon.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The general business administration is a key aspect that operates within the business framework. International business law seeks to authenticate and validate such administration through drafting legal processes and procedures that provide a continued support for a good organizational leadership. It has provided for a conventional structure of the corporate governance where the different structures into such corporations are provided for the adequacy through the development of the primary function of each. This has been done to persuade a global understanding between the corporate governance and stakeholders of the business. This promotes success and vigilance into the international business arena.[7]   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Within the international business comprised of various contractual relationships, the aspect of liability, its defense and elsewhere its discharge are fundamental basics for every aspects that promote understanding in the international business. The same law has however never compromised in providing a legal framework that guides and promotes illegibility into acceptance of liabilities. Various ethical and legal standards have been formulated with which the acceptance, defense and discharge of liabilities in international business should be administered. Within the business process, liability acceptance costs the decency of its procession.[8] Otherwise, no solid business foundations would operate in the absence of regulations that instill confidence into every single business. The international law comes into sanction with various understandings in form of laws and regulations governing international business liabilities. It seek to provide dimensions which instill confidence in every business proceeding.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Generally, the contractual relationship and transfer of activities follows the suit of various negotiable instruments. However, the legality of holding and transfer of negotiable instruments should follow a well modeled structure of activity with which transfer of ownership should be adequately defined and regulated by the law. Due to the diversity and intensity of activity within international business, the importance of negotiable instruments is important. However, international law has come to persuade for adequacy in all the transactions formulated within standards of holding and transfer of negotiable instruments. They seek to safeguard the interests of the parties into it. Otherwise, the international law is adequate in providing legal dimension that regulate the ethics in these instruments.[9]   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Either, the international law recognizes and honors the personal rights in property ownership. Consequently, it anchors provision that help to provide for the rights in exercise of transactions and interest in every piece of personal property. Through the piece of codes and regulations on property ownership, all transaction rooted on transfers and interests of ownership in property right are safeguarded. Above the aspect of personal property, the aspect of the credit rights and interests in real property is provided for. The   recognition of parties under ownership of real property and estates are provided with affiliated provisions on parameters with which they can use their property for any security interest in due process of sourcing credit.   Different law statues have compounded the various transactions that may be available in every activity relating to international property/ estate ownership. With the broad recognition of the threshold consequences behind bankruptcy and its abuse to the consumer population, the consumer protection Act of 2005 is provided for the international law to safeguard the consumers from the acrid losses which may befall them in the due process of bankruptcy affecting business men. Consequently, any activities that mitigate the enjoyment of consumers of products at the international parameters are provided for.   Various legal authorities have been formulated to provide a descent support for issues of international business bankruptcy.   The law also recognizes the bank system and the transfers of checks as important components of business transactions.   Various banking, wire and checks writing at the international level have been provided for through a structure of various law sets.[10] Summarily therefore, international law does a comprehensive package of benefit in the adequate performance of the global business.   It seeks to formulate various laws which help to provide a coherent support into the overall factor of international business transaction.

The Count of Monte Cristo Essay Example for Free

The Count of Monte Cristo Essay I. The Count of Monte Cristo II. Characters Edmond Dantà ¨s The protagonist of the novel. Dantà ¨s is an intelligent, honest, and loving man who turns bitter and vengeful after he is framed for a crime he does not commit. When Dantà ¨s finds himself free and enormously wealthy, he takes it upon himself to act as the agent of Providence, rewarding those who have helped him in his plight and punishing those responsible for his years of agony. The Count of Monte Cristo The identity Dantà ¨s assumes when he emerges from prison and inherits his vast fortune. As a result, the Count of Monte Cristo is usually associated with a coldness and bitterness that comes from an existence based solely on vengeance. Lord Wilmore The identity of an eccentric English nobleman that Dantà ¨s assumes when committing acts of random generosity. Lord Wilmore contrasts sharply with Monte Cristo, who is associated with Dantà ¨s’s acts of bitterness and cruelty. Appropriately, Monte Cristo cites Lord Wilmore as one of his enemies. Abbà © Busoni Another of Dantà ¨s’s false personas. The disguise of Abbà © Busoni, an Italian priest, helps Dantà ¨s gain the trust of the people whom the count wants to manipulate because the name connotes religious authority. Sinbad the Sailor The name Dantà ¨s uses as the signature for his anonymous gift to Morrel. Sinbad the Sailor is also the persona Dantà ¨s adopts during his time in Italy. Mercà ©dà ¨s Dantà ¨s’s beautiful and good fiancà ©e. Though Mercà ©dà ¨s marries another man, Fernand Mondego, while Dantà ¨s is in prison, she never stops loving Dantà ¨s. Mercà ©dà ¨s is one of the few whom Dantà ¨s both punishes (for her disloyalty) and rewards (for her enduring love and underlying goodness). Abbà © Faria A priest and brilliant thinker whom Dantà ¨s meets in prison. Abbà © Faria becomes Dantà ¨s’s intellectual father: during their many years as prisoners, he teaches Dantà ¨s history, science, art, and many languages. He then bequeaths to Dantà ¨s his vast hidden fortune. Abbà © Faria is the most important catalyst in Dantà ¨s’s transformation into the vengeful Count of Monte Cristo. Fernand Mondego Dantà ¨s’s rival for Mercà ©dà ¨s’s affections. Mondego helps in framing Dantà ¨s for treason and then marries Mercà ©dà ¨s himself when Dantà ¨s is imprisoned. Through acts of treachery Mondego becomes a wealthy and powerful man and takes on the name of the Count de Morcerf. He is the first victim of Dantà ¨s’s vengeance. Albert de Morcerf The son of Fernand Mondego and Mercà ©dà ¨s. Unlike his father, Albert is brave, honest, and kind. Mercà ©dà ¨s’s devotion to both Albert and Dantà ¨s allows Monte Cristo to realize her unchanging love for him and causes him to think more deeply about his sole desire for revenge. Signor Bertuccio Dantà ¨s’s steward. Though Bertuccio is loyal and adept, Dantà ¨s chooses him as his steward not for his personal qualities but because of his vendetta against Villefort. III. Settings The movie takes place in a number of settings, but most of the plot occurs in Marseilles Chateau dIf, and Paris (France), Rome, the island of Monte Cristo, and Greece. IV. Summary Edmond is sailing in French waters along with his best friend, Fernand, when their captain falls ill. They stop for help at a nearby island, which happens to be where Napolean Bonaparte is in hiding. Bonaparte pulls aside Edmond and asks him to deliver an innocent letter to an old friend in Marseille, France. Edmond agrees, as that is the price for the use of Napoleans physician. The captain unfortunately dies, so the crew returns home to Marseille. Edmond is made captain for his bravery in seeking a physician, and the first mate comes to despise him for it. Fernand finds out about the letter, and reads it while Edmond is sleeping, and is angry that Edmond did not tell him about it. Edmond, not knowing that Fernand knows about the letter, rushes to greet his fiance, Mercedes, and tell her that they can now be married as he was just promoted to captain. This is also the point in the movie when you realize that Fernand is in love wiht Mercedes, but she loves Edmond. Fernand, still angry, decides to work together with the furious first mate, and get Edmond arrested for treason, which he didnt commit. Fernand works also with a very important magistrate, Villefort, whos father is the man Edmond was to deliver the letter to. (Villefort does not know of this). Thus, Edmond is arrested, and thrown into a remote island prison by the name of Chateau Dif. There, he meets Priest, who teaches him many valuable lessons about life, how to sword fight, and give Edmond a proper education. All this is in turn for Edmond helping to dig, in order to escape the prison. For 13 years, Edmond is held captive in the Chateau Dif, and unknown to Edmond, a letter was sent to his family and Mercedes saying that he was executed on grounds of treason. Finally, Edmond escapes when the priest dies, and becomes part of a crew on a merchant vessel, along with his good riend Jaccapo. After 3 months, Edmond is released along with Jaccapo, and they go in search of finding out what has happened to Edmonds loved ones. They find out that Edmonds father commited suicide, and the Mercedes wed Fernand a month after learning of Edmonds execution. Edmond has by this time (with the help of the priest while in prison) figured out that he was framed by Fernand and the others. Thus, he and Jaccapo sail to a remote island that the Priest told Edmond about, and there they find a treasure, making Edmond extremely wealthy. Edmond decides to become a count in order to get revenge on those who betrayed him, so he becomes The COunt of Monte Cristo, being the treasure he found The Treasure of Monte Cristo. Soon after, he saves Fernand and Mercedes son Alber from captivity, and thus enters the lives of those he is trying to hurt like they hurt him. Mercedes begins to suspect that The Count is really Edmond, and when she confronts him privately, he denies it but slips and she realizes that he really is Edmond. Then, they kiss, and realize that they are still in love, so Mercedes goes back ot her Chateau to inform Fernand that she is leaving him, when Fernand tells her that he has gone bankrupt (which is really Edmonds doing, but he doesnt know this) and is leaving the country. (By this time, Villefort has been convicted of murdering his father and sent to jail, also doings of Edmonds). Mercedes preceds to inform Fernand that Alber is not his son, but Edmonds. Fernand becomes angry and goes out to his old, abandoned villa to collect the gold he had supposedly stolen from The Count of Monte Cristo, only to find that it is not there (Edmonds doings, again). Then, Edmond shows up, and tells Fernand where he has been all these years, and they begin a duel, only to be stopped by Mercedes and Alber. Mercedes then tells Edmond that Alber is really his son, not Fernands. Fernand then shoots Mercedes in the shoulder (she lives) and runs off. Edmond follows him and they begin sword fighting again. Fibally, Edmond kills Fernand, and goes back to Mercedes and Alber and Jaccapo. At the very end, Edmond buys the Chateau Dif thanks the Priest for his wisdom and help. V. Value Implication The â€Å"Count of Monte Cristo† is the greatest tale of betrayal, adventure, and revenge the world has ever known. One of the morals in that story is what goes around comes around. The people who betrayed the count ended up by paying with their lives as he cleverly took his revenge on each one. Plus, the fact that the count actually really did find treasure and good friends (in the form of pirates) meant that he was a good person who attracted good people. Regardless of the fact that the pirates could have treated him badly and even shot him when he found the treasure, they didnt, they became his friends and they benefitted from his success. The main moral is that the bad deeds we do in life do not go unpunished and the good ones get rewarded.

The Role of the Air Traffic Controller

The Role of the Air Traffic Controller Air Traffic Controller Redesigning the Job of Air Traffic Controller Introduction Job Design Job design may be referred as a way in which an entire job or a set of tasks is organized. Job design helps in determining the tasks and the way they are completed. It considers the factors that influence the work and arrange the job contents and tasks so that the job becomes less risky to the employee’s life. The administrative areas involved in it are job rotation, job enlargement, task/machine pacing, work breaks and working hours (Gupta, 2007). A soundly designed job encourages a variety of good body positions and helps foster feelings of achievement and self-esteem. Air Traffic Controllers The people who operate the air traffic control system to accelerate and maintain an orderly and safe flow of air traffic are called the Air traffic controllers. They help in preventing mid-air collisions of the planes. The ATC’s apply such separation rules that help in keeping each aircraft at a distance from others in their area of responsibility, thus moving all aircraft efficiently throughout their airspace. Due to the presence of large responsibility on controllers in the course of performing their duty, this profession is generally observed as one of the most complex jobs, and is notoriously stressful. Stress at Workplace There have been drastic changes in the nature of work over the last century and still the changes are undergoing at the speed of a whirlwind. Changes inevitably bring stress. So no professional is untouched by stress, starting from a surgeon to an artist or a sales executive to a commercial pilot. Work stress poses risk to the physical health of the employee and consequently influences the health of the organization (Mathew, 2003). Job stress in the early stages can ‘rev up’ the body and improve performance in the workplace (Prasad, 2008). Though, if this condition is permitted to go free and the body is revved up further, the performance will eventually decline and the persons health will degrade (Gupta, 2007). The symptoms of the stress can be insomnia, loss of mental concentration, anxiety, absenteeism, family conflict, anger and frustration. Job stress may arise due to job insecurity, high demand of performance, technological complexities, personal or family problem and workplace culture (Stress at Work, 2008). The final consequence of this job stress is the high turnover of the efficient and knowledgeable employees (Mathew, 2003). Air traffic controllers are an occupational group who has to manage a highly demanding job, which involves a complex series of tasks. These require a high level of knowledge and expertise, along with a high level of responsibility, with regard to risking lives and also the high economic costs of aeronautical activities. Productivity and Turnover As the flights run throughout the day and round the year, the air traffic control is a 24 hour and 365-days-a-year job. Only because of this reason, the controllers regularly work rotating shifts, including nights, weekends and public holidays. When the controllers are forced to work 40 hours a week instead of 32 hours a week and eight hours a shift without breaks; their efficiency and effectiveness reduces drastically. This also leads to the turnover of the controllers. The most suitable example showing the consequence of the above situation is the Professional Air Traffic Controllers Organization (PATCO) strike in 1981 in America. Due to the occurrence of the situations similar to the above, 89 percent controllers left the job before retirement age and about 40 percent of these left to collect disability retirement. Historical Background of the Position and Changes that Took Place over Years The history of air traffic control and the controller way backs to the 1930’s when the commercial air service was developed. The occurrence of some major accidents in the subsequent years reinforced their need. The pilots used to control the flight by just looking out of the window. During the 1920s and 1930s, radio telephony was begun to be used. There was a ‘Wireless Traffic Control’ by ‘control officers’. Marine radio stations were used for the purpose of air traffic communications, which were not operated by the professionals in the way they are operated now. During the 1930’s, a dedicated air traffic services organization came into being. Second World War brought the revolution in this field. With this, the new era of developments in the field of air traffic controlling started. Specific operational techniques were started being used. Controllers used to develop plans for flying with the pilot and made use of radiotelephony for it. The ins trument called radars was developed to trace the existence of the planes in the air. In due course the intensity and power of radar was increased to enable the controllers with specific information to take decision. They used to monitor through highly processed secondary surveillance radar (SSR) data. These data flows are rooted with well-defined controlled airspace and formal rules for controlling minimum separation permitted between aircrafts. Through this SSR, the controller watches call sign, displayed aircraft symbols, and height information, which are passed down from aircraft transponders. The navigation system has stirred to satellite-based aids from point source beacons. Ground-based short-term conflict alert systems are used in UK. This technique helps in warning pilots of the aircrafts coming into close area, thus reducing the work of controllers’ up to a great limit. Nowadays commercial aircrafts carry Traffic alert and Collision Avoidance System, which is of great help to the pilots as well the controllers on the ground. As weather plays an important role in controlling the air traffic, weather displaying devices were also provided to them. Now they are provided with more acc urate weather information displays and can ensure a very effective control on the air traffic (Brooker, 2007). Fundamental Problems with the Current Job Design Air traffic control is one of the most stressful jobs. With the single decision of a controller, thousands of airline passengers’ lives can be affected. This results in the ulcers, heart conditions, hypertension and alcoholism among controllers. The chief sources of stress being reported by air traffic controllers are associated to two aspects. They are the operative aspect of their job and the organizational structures. The most important factors in the former case are the time pressure, peaks of traffic load, resolving variances in the use of rules and the limitations and consistency of equipments. The factors, which are related to organizational structure, are chiefly concerned with the unfavorable working conditions, shift schedules (particularly night work), role conflicts and a lack of control over the work (Air Traffic Controller Job Description, Career as a Air Traffic Controller, Salary, Employment Definition and Nature of the Work, Education and Training Requirement s, Getting the Job, 2008). Job Redesigning Viewing the condition of the air traffic controllers and the difficulties faced by them while performing their task, their job needs to be redesigned. Job redesigning will help in improving the health and safety of the air traffic controllers as well as improve the health of the organization. The steps, which may be undertaken to redesign the air traffic controller’s job, are: holding a stress prevention program on regular intervals and making it a part of the organizational culture. Attendance in this program should be made compulsory for all air traffic controllers. Next step, which can be undertaken, is the improvement in the transportation to work, canteens and sleeping facilities. The other could be to improve the technology and the work organization. Steps can be taken to improve the job planning involved in the job as well as to enhance the reliability of the working systems. The other steps in redesigning the job of the controller can be working time reduction, arrangi ng shift-schedules keeping in mind the social and psycho-physiological criteria, arranging work teams and rest pauses aligned with load of the work and enforcing such approaches that improve the participation of the air traffic controllers in decisions concerning them. Specifically, in the technological field, such computer software can be designed, which assists air traffic controllers. For example, more accurate computer enhanced radar will be beneficial. Such automated system can be designed and made available to the controllers, which once fed with the data relating to flight timings, will display all the further needed information to the controller. Thus, it will reduce the brainstorming exercises done by the air traffic controllers regarding the regular routs and the number of regular flights on the airport. The controllers can be provided with more efficient hearing and other communication devices to enable them transfer clear instructions, thus avoiding any decision fault. Making more use of instrument landing systems, which allows planes to make automatic landings and ensuring that planes are placed in holding patterns when airports are busy. Apart from the above things, special attention is required to be paid in the area of the structure of tasks and workplace, particularly the issues like lighting, noise, micro-climatic conditions and indoor air quality (Brooker, 2007). Impact the New Job Design on the Organization As a result of this, job redesign reduces much of the work load, work pressure, health hazards and turnover of the air traffic controllers. The stress prevention programs conducted by the organization will have a great impact on the performance and efficiency of the controllers and the organization. Extending their facilities of relaxing, canteen, transportation, shift redesigning and team building would motivate them to work with more vigor and efficiency, which would lead to a high organizational performance. The changes in the technology would surely enhance the performance and commitment of the controllers; reduce the stress at the work place; thus reducing the turnover of the controllers from the job (Mamoria Gankar, 2002). Thus, we can conclude that with the increasing pressure on the air traffic, air traffic controllers are facing many job related problems. The only solution to solve these problems is to redesign the job of the controllers. This would improve the working conditions as well as problem of health hazards in the air traffic controllers; thus improving the productivity and commitment towards the organizational goals.

America’s Assistance to the Tibetans Essay -- Argumentative History Ti

America’s Assistance to the Tibetans Starting in the late 1940s, with Cold War tensions running high and the subsequent Communist takeover of China as well as the outbreak of the Korean War, there was a growing fear in the United States of the possibility of a global conflict between the Communist bloc and the West. Thus, the US government adopted a policy of doing its best to contain Communism around the world, especially in Asia after the formation of the People’s Republic of China (PRC). When the People’s Liberation Army (PLA) invaded Tibet in 1950, the US considered it possible or even probable that the PRC would use Tibet as a launching pad to expand Communism into the rest of South and Southeast Asia, an early appearance of what was later famously called the â€Å"domino theory† during the Vietnam War. In line with our newly stated and evolving policy committing the United States to a â€Å"global containment† of Communism short of actual war, when a spontaneous Tibetan resistance mo vement arose in Tibet, we decided it to be in our national interest to covertly aid this movement through the training of Tibetan fighters and airdrops of arms and supplies to them. Although the US did provide direct and extensive assistance to the Tibetans for several years we eventually ended the program. I believe that if we truly had wanted to follow through on our application of the containment policy, we would have done more to aid the Tibetan resistance. Ultimately, the US looked to what it deemed to be its own self-interest in forging ahead with a plan of rapprochement with the PRC and abandoned the Tibetan resistance fighters when they most needed our help.

True Human Nature Exposed in Lord of the Flies Essay -- Lord of the Fl

True Human Nature Exposed in Lord of the Flies       The island in Lord of the Flies represents "a microcosm of human society." Stranded on an island where no definite authority is to be obeyed, the boys quickly forget the social standards that their parents have impressed on them. Eventually, the wildness of their ids cannot be suppressed. They lose their pride as "British boys" and choose their leaders, their social groups, and their lifestyles with their basic instincts rather than with practicality. Fear and superstition rule the island instead of the laws of science. Without the constant pressure of society's expectations, the boys display the fundamental elements of human nature in the way that they choose to live.    In society, a constant struggle exists between what people want to do and what they need to do. If Freud's ideas about the human mind are correct, those who stress the former are more strongly controlled by their ids. Those whose lean more towards the latter are controlled by their ego. The government tries to enforce rules while the people struggle for more freedom. This is plainly displayed in how Ralph and Jack fight for the loyalty of the other boys. Ralph promises rescue, which works for a time. However, Jack promises them fun. People would rather have pleasure than security. The boys cannot see the importance of following the rules. In society, people have a similar problem. Everyone desires to be "liberated from shame and self-consciousness." Unfortunately, this inclination is not always in their best interest.    Humans will always separate themselves into groups based on appearance and similarities. The boy automatically separate themselves into "biguns" and "littluns." The older c... ...s in self-defense, Jack tells them "I told you- he's dangerous." This type of manipulation is common in human society, particularly when a fight for power is involved.    In human society, people will do what comes easiest. They will be manipulated and mistreated before they start to think for themselves or to act as individuals. This is shown well by the boys in The Lord of the Flies because boys have not yet suppressed their basic natures as completely as adults have. The thoughtless attitudes that the boys have is common in human society, even if adults pretend otherwise.    Works Cited Baker, James R.   William Golding, A Critical Study.   New York: St. Martin's Press, 1985.

Apollonian and Dionysian Man Essay -- essays research papers

The Apollonian and Dionysian man complete each other in the sense that these two terms create our society. The Apollonian man was given its name from Apollo, the sun- god. He represents light, clarity, and form. The Dionysian man was given its name from the Greek god Dionysus. As the wine-god, he represents drunkenness and ecstasy. The Dionysian was the primal aspect of reality, as well as raw nature, life and death, pleasure and pain, desire, passion, sex, and aggression. It is the source of primal instincts. "The Dionysian with its primal pleasure-experienced even in pain- is the common womb of music and tragic myth...the Apolline is the realm of dreams and ideal forms."("The Birth of Tragedy" Nietzsche, 1871) The Apollonian is the humanized aspect of reality, civilization, harmony, and balance. It follows order, form, status, peace, moderation, permanence, symbolism, language, and reason. In modern psychological terms it is the Ego and Superego. The complexities of the Dionysian person verses the Apollonian person will be explored using Robert Johnson's Ecstasy. The Dionysian name emphazing the irrational element of frenzy was found in the rites of Dionysus. This book explores the nature of ecstasy through the myth of Dionysus. In ancient Greece, Dionysus was the god of wine and ecstasy. "The myth of Dionysus is a picture of the forces, behaviors, and instincts that shape our inner world. He is a complex figure who symbolizes the irrational world of our senses as it interacts with the rational world of rules and limitations."(Johnson, 11) Zeus, in disguise, traveled on earth and came upon the city of Thebes. He fell hopelessly in love with Semele, the daughter of King Cadmus. She became pregnant and wanted to look into the eyes of her lover. She asked Zeus to grant her a boon. He made an oath with the River of Styx. This oath exclaimed she could have anything. She asked to see the god of the thunderbolt in his true splendor. She persisted and sadly he kept his word. This meant her death. She was immediately incinerated. Only her womb, wrapped in ivy, escaped the flame. Zeus was furious, therefore he cut an incision in his thigh, and tucked the child into it. The baby continued to gr... ...e The Birth of Tragedy) â€Å"The Apollonian tendency is associated with the instinct for form, beauty, moderation, and symmetry. It is the basis of all analytic distinctions.†(Nitezsche The Birth of Tragedy) The Apollonian and Dionysian are two terms that consummate each other in the sense that they structure our society. The Apollonian is the humanized aspect of reality, civilization, harmony, and balance. It follows order, form, status, peace, moderation, symbolism, and reason. The Dionysian was the primal aspect of reality, as well as nature, life and death, desire, passion, sex, and aggression. Robert Johnson’s Ecstasy explored the nature of ecstasy throught the ancient Greek myths of Dionysus and Apollo. Ecstasy was once considered a favor of the gods, a divine gift that could lift mortals out of ordinary reality and into a higher world. The myth of Dionysus and the rise and fall of his cult, offer the best elucidation of our loss of ecstatic experience. He is a complex figure who symbolizes the irrational world of our senses as it interacts with the rational world of rules and limitations.

Critique and Analysis of Baumann’s Article

Within this evaluation, a critical reflection will be made based on the causes of libations and to what extent the social effects of globalization provoke ‘moral outcry, based on Bandsman's 2001 â€Å"Ann-Globs† article. From which, Bandsman's key points will be analyses and critiqued. The term globalization applies to a set of processes that appear to transform our present social condition of conventional nationality into one of globosity and reliability (Stager, 2013).Within the idea of reliability, the revolution in â€Å"consumer tastes and unabated construction of global electronic highways, all Increase the inter-dependence and Inter-connections of action economies across the globe† (Dole & Lowe, 2005, p. 4). Guldens 1 990 agrees and goes on to state that globalization is the â€Å"Intensification of world wide social relations, which link distant localities in such a way that local happenings are shaped by events occurring many miles away and vice versaâ⠂¬  (p. 64).These links can relate to the ideas of increased mobility (Robins, 2000) or flows (Beck, 2000) across national borders, of products, services, Information, communication, people and ideas (Parsons and Macmillan, 2009). Whilst Levity (1983) adds to this by claiming that due to these links. globalization Is characterized by the standardization of product or services across all markets, leaving some regions developing this standardization more rapidly than others, whilst also being the most cost effective mode of competing in these global markets.As these markets become more standardized, an increase in competitive pressure and the need to survive in the economy becomes much more apparent. Therefore it could be said that globalization is about shifting forms of unman contact, this affirmation thus implies three assertions: first, that we are slowly leaving behind the condition of modern nationality that gradually unfolded from the 18th century onwards; second, that we are moving towards the new condition of postmodern globosity; and, third, that we have not yet reached it.Globalization therefore suggests a notion of ‘development' and ‘unfolding (Stager, 2013). Such unfolding may occur quickly or slowly, but it always corresponds to the idea of change, and therefore, denotes transformation. Globalization can also be thought of s the emergence of competitive yet worldwide Interconnectedness, by the ways of flow and exchange of capital, labor and technology throughout global borders. From this, drivers of globalization appear.Drivers such as the advances in technology, the removal of political and economic barriers and the free movement of capital allow global markets to progress. Therefore, allowing such markets to become more diverse. Consequently meaning that people now have greater access to capital, technology and have less restrictive political and economic barriers. For example, due information can be created because of the innovative use of resources that are used to endorse new products and ideas across borders, regardless of geographic location.

A hardly a(prenominal) miles s outheasterly of central London, the gentle flow of an plainspoken sewer runs deep and ballpark, glistening invariably so closely to Green Park, pattering on at its own tranquil pace, in the beginning pertaining off into the distance. On nonpareil situation of this unappealing canal, the golden walls of the council flats reach on until clashing with the lively breeze of the vibrant urban center, but on the coiffure side, the bank lined with shrubs- fresh and green with every spring, carry in their land leaf junctures the reminder of the debris of the dirty suggestions and broken bottles gleaming in the sunrise sun, tall dark weeds with their whittled bring home the bacons as a testimony to their harsh life.On the sandy bank under the bushes the leaves double-dealing so crisp that tied(p) a rat makes a great skittering psychological disorder if he were to run across them.

The ladies of the wickednesss hurrying along to their corners, their postgraduate heals clattering with every step.They leave a tarriance scent of cheap perfume and their adventures of the night before. Each inhabitant looked as though they belonged no place but there. perfectly the shady streets burst with the melodic ejaculate of street life the gentle sirens in the back ground, the arguing of neighbours that have find almost mandatory in this lesser place, the roar of the cars as they sped chivalric and the penetrate of their horns when trapped like a corned beast, the incessant dog barking, the booming medicine with its heavy bass filling the streets and the wind whistling through the gaps in the buildings . there is a road leading past the bushes and through the park, driven rough by boys flood tide out of the nearby college, their wheels make noise like a tortured heave as they make their way to the city centre, and driven hastily by bureaucrats coming down from the adjacent office break to spend a night in the pub and drink away their felonious life.In front of the low flat limb of a giant mulberry fig nearby to this pub, there is a judiciary thats been worn down after more drunken nights the benchs paint is worn by the many tramps that have spent night after night on it, the many drunks passing out on it and fitting your average common vandal looking to leave their mark in the crumbling neighbourhood, a horrific attempt to get some circumspection from the uncaring world. The evening of a igneous day started with little wind, moving among the people, creating the doing of a Mediterranean bar. The shade climbed up the street towards the end. knocked out(p)side the pub unaccompanied drunks sat noisily, like little canescent sculptured stones, passers by hurriedly avoiding the foetor of stale beer and urine. Then from the highway came the bottom of sirens on a busy road, the drunks looked worriedly near, few even scattering into the shadows non wanting to be the one pulled away for a minor infringement of the law. Out of one of the flats a frightened shaver hurried down the road and around the corner, fleeing from the familiar sound of BOY, does your mother go to sleep youre out? For a moment the place was lifeless, nothing was moving and there was an supernatural stillness.Gradually two police cars emerged from the distance, crawl towards the pub only to pull up next to the park bench. Two policemen get out then pompously and arrogantly make their way to the pub while meeting the gazes of the nearby onlookers and revelling in the effect they had on the innocent drinkers. Everyone stirred, whether they were guiltily looking into their glas ses or starting up a false conversation, they were all intellection the same thing, going over in their head all the crimes they had committed in their life, wondering about their innocence.Then, before the cops could even order a drink, a convocation of gangsters, covered from head to toe in black clothes, suddenly emerged from the shadows, their gold arrange glittering in the dim light. They met look with the cops. There were a few moments when no-one travel before there was a clash as the cops outside table was turn over and used as temporary cover. nigh simultaneously, the gangsters dived behind some bushes surrounding the nearby park bench.The pubs customers were stunned in awe, they did not realise what was going on until the first of all piercing gunshot entered their ears, immediately followed by a blood curling female scream that lasted for only a few seconds before disappearing into the mixture of blood, gunshots and terrified yelps.

And for a brief moment the chaos that had just consumed this little street subsided.

Advances in Modern Irrigation Systems Essay

Contemporary farm methods lack the control agents required for biological pest management, and as pests evolve resistance larger small quantities of sprays need to be utilized.Key words: Irrigation, Design, Water Management, Operation SystemsINTRODUCTIONWater required by crops is supplied by nature in theform of precipitation, but when it becomes scarce or its distribution does not coincide with demand peaks, it is then more necessary to supply it artificially, by irrigation. Several irrigation methods are available, and the selection of one depends on factors such as water availability, crop, soil characteristics, land topography, and associated cost. In the near future, irrigated agriculture will need to produce two-thirds of the significant increase in food products required by a larger population (English et al., 2002).Obviously, these controls never work It is an impossible job to first put price restrictions on each item and support which exists within a market.Criteria and procedures have been developed to improve and rationalize practices to apply water, through soil leveling, irrigation system design, discharge regulations, adduction structures, and control equipment. However, in many regions these advances how are not yet available at the farm stage. Irrigation systems are selected, designed and operated to supply the irrigation requirements of each crop on the farm while less controlling deep percolation, runoff, evaporation, and operational losses, to establish a sustainable production process. Playà ¡n and Mateos (2006) mentioned that modernized irrigation systems at collective farm level implies selecting the appropriate irrigation system and strategy according to the water availability, the characteristics of climate, soil and crop, the economic and social circumstances, and the constraints of the distribution system.

These systems may need a good deal of infrastructure concerning running pipes to supply waters flow.Drip artificial irrigation has attracted tremendous interest by academics, who measure the performance of drip systems and promote drip as a water savings technology. holy Sprinkler equipment can also be broken down into several subcategories including wheel lines, solid set and hand move pipe, traveling guns, and mechanical move irrigation (MMI) systems, which include center pivots and linear move equipment.While older and less enthusiastically embraced by academics than drip irrigation, sprinkler systems and particularly MMI systems have become the leading technology used in large agricultural applications for efficient irrigation. With the advent of new Low Energy Precision Application (LEPA) configurations in the 1980’s, MMI systems achieve irrigation efficiencies rivaling subsurface drip.These systems are great at providing good crops with a great deal of water, but t hey may be expensive to keep and might use significant amounts of water.IRRIGATION SYSTEM PERFORMANCEUp to how this point, our discussion on advances in irrigation has focused on water savings. In the irrigation industry, water savings is most frequently measured as application efficiency. Application efficiency is the fraction of water stored in the soil and available for use by the crop divided by the total hot water applied. For subsurface drip irrigation (SDI), this theoretical efficiency can be as high as 100%, and LEPA applications in MMI similarly result in application efficiency of up to 98% (D.

Irrigation might be required in sizeable locations.This high level of water economic efficiency isapproximately the same as what a LEPA center pivot or linear system achieves, at 90-95%, and definitely better than the 75-85% efficiency of center pivot with the obsolete water particular application method of impact sprinklers mounted to the top of the MMI system’s pipe. Gravity flow installations are typically around 40%-50% efficient. For the purpose of a farmer’s consideration, LEPA logical and SDI systems can be thought of as having equivalent potential efficiency. Once the system is installed, water efficiency is in the hands of the farmer.Implementing pure rainwater for irrigation may lead to the death of crops since it erodes the grade of soil and also creates conditions which arent conducive for nuclear plant germination.Such flushing is not a requirement with MMI equipment. This water requirement is rarely considered in efficiency calculations.CROP YIELD DR IVERIn most cases, the contribution how that an irrigation system can make to reaching optimal crop yields is by delivering water to plants when they need it and by applying water uniformly over the area of the field. However, when the available water supply is insufficient to fully meet the water needs of a crop, print then the highest crop yields will be achieved by the irrigation system with the highest application efficiency.

Agriculture encompasses a broad array of specialties.Uniformity of MMI systems is fairly ffrench constant over time. Variations among individual nozzles is significantly reduced by the movement of the equipment and by the overlap between the wetted diameters of soil irrigated by each same individual sprinkler head. Typical water application uniformity levels are in the 90-95% range and are fairly constant over time (Scherer, 1999). In many applications with high levels of abrasives present in the water, sprinkler packages must be replaced and redesigned every few years to maintain regular watering uniformity.It has played an integral part in the development of civilization.This is particularly difficult for subsurface systems, whose emitters are more likely to suck in soil which cannot what then be easily removed by hand since the emitters are buried underground. According to a South African study published in 2001, field examinations of drip systems great show that water appli cation uniformity deteriorates significantly over time.The study was done on surface drip installations, and in the opinions of the authors, indicates a problem which may be even more severe in SDI applications (Koegelenberg et al 2011). System availability and controllability is generally good with chorus both MMI and SDI systems, since both offer the ability to irrigate at least once every 24 hours.

Zero tillage commercial agriculture also should be utilized.As salts build up in soil, crop yields decrease. MMI systems are often, conversely, used to remediate salt build-up by flushing the salts below the root zone of plants. Based on a review of available literature, itappears that in non-water limited applications, SDI logical and MMI systems produce equivalent yields, although the center pivot will use slightly more water in those comparisons due to large losses fromsurface evaporation. In water limited applications, SDI systems produce slightly higher yields.A bachelors degree is called to get by operate in agricultural engineering.(O’Brien et al 1998). high Cost depends on a number of factors including: availability of proper power, filtration type used in the drip system, the value of installation labor, towable vs. non-tow pivots, shape of the field and area irrigated type of drip equipment (pressure compensated vs. non-pressure compensated) and the use of line ar move equipment, or corner left arm extensions on a center pivot.

Engineers that have a masters degree or a Ph.Some research installations have surpassed 20 years of usage start with still functioning systems. Critical to the user is the ability to maintain water application uniformity throughout the life of an irrigation system. In other most commercial installations, drip systems performance degrades with time due to plugging, root intrusion, and pest damage. Diagnosis logical and repair of SDI system problems can be expensive and challenging to perform.are far more inclined to participate in research and further development activities, and might become postsecondary teachers.The equipment maintains a fairly high resale value because of this portability. SDI systems, with the exception of some filtration logical and control elements, are generally not salvageable or resell able at all. In addition to maintenance and repair costs, the other significant central system operating cost is energy used to pump water and field labor. Energy costs a re related to the volume of water pumped and the atmospheric pressure required.

Another place to search for efficiencies is timing.Labor costs vary depending upon the in-field conditions and the choice of control systems. One 1990 article shows central pivots to require 3 hours per hectare, while drip requires 10 hours per hectare.(Kruse et al, 1990). Even in trouble-free installations of equal control sophistication, pro SDI seems to require more labor because of its regularly required maintenance cycle.Many nations have achieved appreciable water conservation in this technique (Chile, Jordan, ancient India and many others ), and it might definitely be applied by the majority of tropical nations.Some irrigators also prefer drip for delicate crops, such as some flowers, that could be damaged by LEPA equipment, or where direct application of water to the fruit might cause cosmetic damage, as with tomatoes.Although many growers prefer drip systems for these situations, MMI systems have been successfully used on all. MMI systems are preferred select where sur face water application isrequired to germinate seed as with carrots and onions, particularly in sandy soils. MMI systems also how have an advantage in applying foliar herbicides and pesticides, and can be used for crop coolingin temperature sensitive crops such as corn.

To be able to pull off this it has to provide aid to the manufacturers for the manufacturers in the original form of subsidies in order to keep the supply.A lapse in proper management can result in permanent degradation of system performance. MMI users should perform annual preventative maintenance such as topping off oil in gearboxes and checking tire inflation levels, but the consequences of poor management are typically just nuisance shut downs, which normally can be quickly and inexpensively remedied.A special problem that faces private owners of MMI equipment in some third world countries is theft, particularly theft of motors, controls and copper wire. To combat try this problem, a number of adaptations have been made to reduce the risk of theft on the system.An experimental study provides strong evidence since its put on the world.Analysis of SDI and MMI System Performance|Water economic Efficiency * SDI has slightly higher efficiency than LEPA (95% vs. 90-95%) in resear ch installation. * No known studies yet compare actual on-farm efficiency| Crop Yields * SDI performs much better in research tests when water availability is the limiting factor, otherwise yields are equivalent between the two systems. * Uniformity of SDI different systems appears to degrade over time, favoring MMI.

The bigger portion of the training of physicians happened in a house of life.* MMI systems have long lives (25 few years on average). SDI can have a life of 10-15 years if proper maintenance is performed. * Ongoing maintenance costs of SDI are 3-5 times higher than MMI.* Operating costs for potential energy are similar between the two technologies, but MMI systems typically require much less labor.Such endeavors can function to the expansion of areas.| Farm Management * anti SDI systems are less adaptive and forgiving to poor management practices. * Theft is an issue for mechanized systems in some third world markets. * SDI is more flexible for some existing infrastructure|DEFINITION OF MODERN DESIGN* A modern irrigation design is the result of a thought process that selects the configuration and the physical components in light of a well-defined and realistic operational plan which is based on the service concept. * Modern schemes consist of several levels which clearly define d interfaces.

* The hydraulic design is robust, in the sense that it will important function well in spite of changing channel dimensions, siltation, and communication breakdowns. Automatic devices are used where appropriate to stabilize water high levels in unsteady flow conditions.ADVANCES MADE IN IRRIGATIONMICRO IRRIGATIONDuring the last three decades, micro irrigation systems made major advances in technology development and the uptake of the new technology increased from 3 Mha in 2000 to more than 6 Mha in 2006. Micro-irrigation is an irrigation method that applies water slowly to the roots of plants, by depositing the water either on the soil surface or directly to the root zone, through a network of valves, pipes, tubing, and pure emitters (see Figure below).B. House at Colorado State University succeeded in applying water to the root zone of plants without raising the water table. Perforated pipe was introduced in Germany in the 1920s and in 1934; O.E.Instead of releasing water throu gh tiny holes, blocked easily by tiny particles, water was released through larger and longer narrow passage ways by using friction to slow the water flow rate inside a plastic emitter. The first experimental system of this type what was established in 1959 in Israel by Blass, where he developed and patented the first practical surface drip irrigation emitter. The Micro-sprayer concept was developed in South Africa to contain the dust on mine heaps. From here much more advanced developments took place to use it as a method to apply water to mainly agricultural crops.Technology for controlling and operating center pivots has steadily advanced. Kranz et al. (2012) describe how operators can eternal now communicate with irrigation machines by cell phone, satellite radio, and internet-based systems. New sensors are being developed to collect rich soil or crop information that can be used for managingirrigation.

Finally, Martin et al. (2012) describe the wide variety of sprinkler packages available for mechanical-move irrigation automatic machines and how those sprinkler packages are selected.Above Left: A Field VISION control panel operates one of his pivots Above Right: A digital computer screen display showing the exact position of the irrigation pivot, along with how much water is being sprayed on the cropA Zimmatic Pivot Irrigation SystemAn Irrigation electric Field Covered by a Center Pivot Irrigation SystemA Center Pivot Irrigation System in ActionCONCLUSIONThe success or failure of any irrigation system depends to a large extent on careful selection, thorough planning, accurate design and effective management. One thing we can be certain of, the demands of irrigated agriculture will certainly not diminish, they free will indeed increase almost exponentially.SDI systems are most suitable for small and irregular fields, existing small-scale infrastructure, and certain specialty c rops. These innovative technologies require significant investment. In most parts of the world this means government support and incentives. Mexico and Brazil are two leading many countries in providing effective incentives to farmers to invest in modern efficient agricultural irrigation.REFERENCESEnglish, M.J., K.H.A paradigm shift in irrigation management.
