Compare the two nineteenth century horror stories Essay
Compare the two nineteenth century horror stories, ââ¬ËThe Black Catââ¬â¢ and ââ¬ËThe Tell-Tale Heartââ¬â¢ by Edgar Allan Poe, showing how Poe uses a range of techniques to make his stories dramatic and effective. ââ¬ËThe Black Catââ¬â¢ and ââ¬ËThe Tell-Tale Heartââ¬â¢ are two of the earliest horror stories ever written; they were written in the 1840ââ¬â¢s by the American author Edgar Allan Poe. Poe was born in Boston Massachusetts in 1809. He tragically died in 1849 following a life of alcohol and drugs. ââ¬ËThe Black Catââ¬â¢ tells us about a man who is in a condemned cell. He is on death row and reflecting on his life and the reason behind the situation he is in. He tells the reader about his love for animals and how he married early in life. His wife allowed him to buy a black cat who never left his masterââ¬â¢s side. However, the narrator tells how he became an alcoholic and started to mistreat his wife and pets. On returning home one night he seized the cat and in fright the cat had bitten him. This made him angry and therefore he cut out one of the catââ¬â¢s eyes. A few days later he took the cat, slipped a noose around its neck and hung it from a limb of a tree. That night the house burnt down and engraved on the wall was the figure of a cat. Later on in the story the narrator tells us of how he found a cat that closely resembled the one he had killed. The cat would never leave his side which started to make him hate the creature. He was walking down the steps of the cellar one day with his wife when the cat followed and sent him headlong down the steps. In fury he picked up an axe and aimed a blow at the cat. His wife tried to stop him so he buried the axe into her brain. He buried the body in the wall of the cellar. The police found the body as the man become cocky and tapped on the wall where he had buried his wife, there was a wailing sound and the police uncovered the body with the cat on the corpses head. ââ¬ËThe Tell-Tale Heartââ¬â¢ tells us about a man who has been accused of being mad. He looked after an old man who had a ââ¬Ëvulture eyeââ¬â¢. His eye was a pale blue and had a film over it. Whenever the eye fell upon the narrator, it made his blood run cold. Therefore he decided to kill the old man. In the week before he killed him the narrator tells us about how he crept into the old manââ¬â¢s bedroom every night at midnight, trying to find the right moment to kill him. On the eighth night the old man became aware that someone was in his room. The narrator says how he could hear the manââ¬â¢s heart beating in his chest and was frightened that the neighbours would hear it. He ran into the room; seized the man out of his bed and pulled the bed on top of him. He then took the planks from the flooring of the bedroom and placed the body there. Once he had replaced the floorboards the police arrived saying that a neighbour had heard a shriek and they wished to search the property. He led them towards the old manââ¬â¢s bedroom and placed some chairs out for them on the exact spot of the body. He began to make typical chat with the officers but could hear the heart of the old man beating louder and louder until it drew the narrator mad and he confessed to the murder. Both stories have typical features of a modern horror story ââ¬â blood, murder, the murders conscience and supernatural aspects. However, the structure of the stories differ. ââ¬ËThe Black Catââ¬â¢ is a longer story and is more detailed. It includes more background description. ââ¬Å"I was especially fond of animals, and was indulged by my parents with a great variety of pets.â⬠This quote shows that ââ¬ËThe Black Catââ¬â¢ tells us about the background of the narrator since he was a young boy. ââ¬ËThe Tell-Tale Heartââ¬â¢ is more concise and includes some very detailed sections but less background. ââ¬Å"Presently, I heart a slight groan, and I knew it was the groan of mortal terror. It was not a groan of pain or of grief ââ¬â Oh no! It was a low stifled sound that arises from the bottom of the soul when overcharged with awe.â⬠This quote shows that ââ¬ËThe Tell-Tale Heartââ¬â¢ has some very detailed sections as the narrator goes into depth about the noise that the old man made. The two narrators have various things in common; they both tell the story in first person and use eyes as an important feature in the story. In the opening paragraph both narrators also say that they have been accused of madness but deny the accusation. ââ¬Å"Mad indeed would I be to expect it, In a case where my very senses reject their own evidence. Yet, mad am I not.â⬠This quote from ââ¬ËThe Black Catââ¬â¢ supports my point that the narrator has been accused of being mad but denies it. ââ¬Å"But why WILL you say that I am mad?â⬠This quote from ââ¬ËThe Tell-Tale Heartââ¬â¢ also supports my point as it is from the opening paragraph of the story and the narrator is asking why he is being accused of being mad. The significant differences between the two narrators are; ââ¬ËThe Black Catââ¬â¢ gives a more in-depth background about his life before the present day whereas ââ¬ËThe Tell-Tale Heartââ¬â¢ goes straight into the present. ââ¬ËThe Black Catââ¬â¢ is also set in different rooms of the house and other areas where as ââ¬ËThe Tell-Tale Heartââ¬â¢ is set in just one room. The relationship between the readier is also different. ââ¬ËThe Black Catââ¬â¢ is wrote as if the narrator is writing a letter whereas ââ¬ËThe Tell-Tale Heartââ¬â¢ is wrote as if the narrator is actually speaking to the reader. ââ¬Å"For the most wild, yet most homely narrative which I am about to pen.â⬠These words suggest to me that ââ¬ËThe Black Catââ¬â¢ tells the story as if he is writing a letter. ââ¬Å"How then am I mad?â⬠This rhetorical question shows that the narrator tells the story as if he is actually talking to the reader. The two narrators in the story get caught as they become too over confident about the hiding place of their victims. They both lead the police to the place that the bodies are buried. Sound is also a major part in the reason for the two narrators getting caught. Poe uses a range of visual and sound techniques to make the stories dramatic and effectible. In both stories sound plays a major part in the narratorââ¬â¢s getting caught. ââ¬Å"Then quickly swelling into one long, loud and continuous scream, utterly anomalous and inhuman.â⬠This quote from ââ¬ËThe Black Catââ¬â¢ suggests to me that the points I have made are correct. The sound makes the story more dramatic and suspicious. It also leads the police to the corpse. ââ¬Å"But the beating of the heart grew louder, LOUDER! I thought the heart must burst.â⬠This quote also suggests to me that the beating of the heart made the murderer go mad and confess. It also adds an eerie effect to the story. Poe also uses visual description in the stories. ââ¬Å"The corpse, already greatly decayed and clotted with gore, stood erect before the eyes of the spectators. Upon its head, with red extended mouth and solitary eyes of fireâ⬠¦Ã¢â¬ This phrase of writing from ââ¬ËThe Black Catââ¬â¢ goes into great visual detail about the corpse which makes it a lot easier to picture the story in your head. The amount of description sets the scene very effectively and makes the reader feel like there telling the story from their own personal experience. The use of evil words such as ââ¬Ëgreatly decayedââ¬â¢ and ââ¬Ëclotted with goreââ¬â¢ also emphasise the fear and terror of the story. Poe uses a range of imagery in the stories; including alliteration, similes, metaphors, onomatopoeias, and rhetorical questions. These all make the stories dramatic and keep the reader interested. In ââ¬ËThe Tell-Tale Heartââ¬â¢ Edgar Allan Poe uses a lot of onomatopoeia and metaphors. ââ¬Å"my blood ran coldâ⬠This quote proves the point that Poe uses metaphors in this story. ââ¬Å"Like the thread of a spiderâ⬠This also proves that Poe uses Similes in this story. Both of these enhance the story as they make it more dramatic and effective. In ââ¬ËThe Black Catââ¬â¢ Edgar Allan Poe uses a lot of alliteration, metaphors and personification. ââ¬Å"My tenderness of heartâ⬠This quote is particularly important as later on in the story the narrators heart is the complete opposite from tender. ââ¬Å"Grew with my growthâ⬠This quote from the story shows alliteration. By using both of these quotes the writer is making the story more effective as he is making it more interesting to read. He is also encourage interpretation from the reader and helping them to feel the emotion of the characters. Poe also uses language devices to make the stories dramatic and effective. These include rhythm, repetition, and rhetorical questions. In ââ¬ËThe Tell-Tale Heartââ¬â¢. Edgar Allan Poe uses a large amount of rhetorical questions. ââ¬Å"How then am I mad?â⬠This is effective in the story as it involves the reader. It does so by encouraging the reader to reflect upon the question and therefore get involved more with the story. Poe also uses repetition. ââ¬Å"He had found all in vain. All in vain; because Death, in approaching himâ⬠¦.â⬠The repetitive phrase all in vain, tells us of the narrators joy at the old mans terror. He also uses a capital ââ¬ËDââ¬â¢ in death. This infers he is using death as a name, suggesting that the old man is death. In ââ¬ËThe Black Catââ¬â¢ Poe uses plenty of rhythm and repetition. ââ¬Å"Have terrified ââ¬â Have tortured ââ¬â Have destroyed me.â⬠In this quote Edgar Allan Poe has repeated the word ââ¬Ëhaveââ¬â¢. He has used a rhythm by pausing at the end of each word and the dashes indicate an intensity of emotions. He has also used evil words such a ââ¬Ëterrifiedââ¬â¢ and ââ¬Ëtorturedââ¬â¢ which again emphasise the fear and terror of the story. This makes the story more dramatic. In both stories Poe also uses capital letters to emphasise words this gives an immediate dramatic impact. In conclusion, Poe uses a range of techniques to make his stories dramatic and effective, many of these are still used by horror writers today. Although ââ¬ËThe Black Catââ¬â¢ and ââ¬ËThe Tell-Tale Heartââ¬â¢ are similar in numerous ways, Poe uses different techniques in each one to make the stories effective in their own particular way.

Health Care Conditions Essay
As we analyze the factors contributing to health care costs we must find a solution that provides high-quality care for an aging population. Improvements to modern medicine are prolonging life causing a schism between a health care system oriented towards acute care and the increasing chronic care needs of older adults. Studies do show that health care costs for older Americans account for one third of all national health care expenditures. This being said the average expenditure for health care services for adults 65 and over is nearly four times the cost of those under 65. More significant changes need to be considered given the financial crisis our health care system faces. Health care costs are not solely due to longevity; consider increased utilization, new medical technologies, general inflation, fraud, and waste and abuse. This paper will discuss one article to be used in my final presentation on health care for anaging population. Data collection procedures The study on chronic health conditions used a questionnaire presented to study participants by in-person and telephone interview using computer-assisted software. They also used the Statistics Canada Canadian Community Health Survey (CCHS) for age prevalence patterns and to show how chronic condition prevalence varies by age group. The use of the CCHS survey for historical data and comparisons is very appropriate for this study. The use of a questionnaire, while not ideal, is appropriate for the large number of participants. The survey sampled approximately 130,000 people aged 12 years or older. In-person interviews are the most reliable, but the downside to using telephone interviews using computer-assisted software is that participants may go through the questionnaire quickly or skip questions if they are unsure. Identity protection for research subjects Confidentiality is the protection of information that an individual has trusted you with and disclosed to you for a particular reason. Informed consent is a process in which the researcher explains to the participant what steps are taken to keep their information confidential and what would happen if there were a data breach. The participant then has the information needed to determine if this is adequate and whether or not to continue with the project. The article does not discuss the steps taken toà protect the identity of participants. There is no mention of patient record abstraction, personal information collected or informed consent. Reading the article, it is an assumption that the only information collected was the age and number and type of chronic conditions for each participant. Study reliability and validity The reliability of this study, that is, the consistency and repeatability of the measure is high. A question related to the number and type of chronic conditions experienced by each participant is reliable and is measuring one topic. The questionnaire meets face validity ââ¬â it is a common-sense assessment and the question measures exactly what they want to study. Data analysis procedures To answer the research questions, the researchers used data from the CCHS survey to develop a baseline of the number of chronic conditions within certain age groups. That data was then projected for 25 years based on the target population which was derived from a model of the economic demographic system (MEDS) projection. The hypothesis, ââ¬Å"The expectation is that, as the large baby boom cohort moves into older age categories, the overall proportion of the population with chronic conditions will increaseâ⬠(Denton & Spencer, 2010), is best answered by projecting the number of people in each age group based on historical data and factoring in immigration, emigration, mortality, and fertility rates. I believe this study is quantitative. It involves randomly selected participants, uses face-to-face and phone questionnaires, the data analysis is statistical and is presented in tables and graphs, and is used to recommend a final course of action. The study design is descriptive, also called observational. Validity is important in descriptive studies; the lower the validity, the more study participants you will need. ââ¬Å"For an accurate estimate of the relationship between variables, a descriptive study usually needs a sample of hundreds or even thousands of subjects.â⬠(Hopkins, 2000) Conclusion In conclusion, the study shows that more than two-thirds of the population over the age of 12 has a chronic condition and 90% of them are over the age of 65. The researchers believe that as the participants move into higherà age groups the prevalence of chronic conditions will increase, which this study proves. The prevalence rate in 2005 is 68.7% and the prevalence rate in 2030 is 71.9% which is an increase of 3.2%. But how does this affect health care utilization and cost? With a modest reduction in the prevalence of chronic conditions, one-third of the projected increase in health care spending could be cut by 2030. In this study, a modest reduction is described as reducing the number of chronic conditions by one. Those with three chronic conditions would be reduced to two, two would be reduced to one, and one would be reduced to none. The strengths of this study are the high reliability and validity of the data recorded from the questionnaires. The data analysis and projections based on the target population, adjusted for emigration, immigration, mortality, and fertility was the best option for this type of study. The weaknesses of the study were the inability to abstract data on chronic conditions from the medical records of the participants, and the exclusion of participants in institutions which resulted in an under-estimation of chronic conditions in older populations. Another weakness noted by the researchers was that there was no record of the severity of the condition. This does not allow for accurate accounts of those cured of the chronic condition during the study period. References Denton, F.T., & Spencer, B.G. (2010).

Cat Evolution
The felids are a rapidly evolving family of mammals that share a common ancestor only 10ââ¬â15 million years ago,[26] and include, in addition to the domestic cat, lions, tigers, cougars, and many others. Within this family, domestic cats (Felis catus) are part of the genus Felis, which is a group of small cats containing approximately seven species (depending upon classification scheme). [1][27] Members of the genus are found worldwide and include the jungle cat (Felis chaus) of southeast Asia, European wildcat (F. silvestris silvestris), African wildcat (F. s. lybica), the Chinese mountain cat (F. bieti), and the Arabian sand cat (F. argarita), among others. [28] All the cats in this genus share a common ancestor that probably lived around 6ââ¬â7 million years ago in Asia. [29] The exact relationships within the Felidae are close but still uncertain,[30][31] e. g. the Chinese mountain cat is sometimes classified (under the name Felis silvestris bieti) as a subspecies of the wildcat, like an African variety F. S. lybica. [4][30] As domestic cats are little altered from wildcats, they can readily interbreed. This hybridization poses a danger to the genetic distinctiveness of wildcat populations, particularly in Scotland and Hungary, and possibly also the Iberian Peninsula. 32] The domestic cat was first classified as Felis catus by Carolus Linnaeus in the tenth edition of his Systema Naturae in 1758. [1][3] However, because of modern phylogenetics, domestic cats are now usually regarded as another subspecies of the wildcat, Felis silvestris. [1][4][33] This has resulted in mixed usage of the terms, as the domestic cat can be called by its subspecies name, Felis silvestris catus. [1][4][33] Wildcats have also been referred to as various subspecies of F. catus,[33] but in 2003 the International Commission on Zoological Nomenclature fixed the name for wildcats as F. ilvestris. [34] The most common name in use for the domestic cat remains F. catus, followin g a convention for domesticated animals of using the earliest (the senior) synonym proposed. [34] Sometimes the domestic cat has been called Felis domesticus[35] or Felis domestica,[1] as proposed by German naturalist J. C. P. Erxleben in 1777, but these are not valid taxonomic names and have only rarely been used in scientific literature,[36] because Linnaeus's binomial takes precedence. [37] Cats have either a mutualistic or commensal relationship with humans.However, in comparison to dogs, cats have not undergone major changes during the domestication process, as the form and behavior of the domestic cat are not radically different from those of wildcats, and domestic cats are perfectly capable of surviving in the wild. [38][39] This limited evolution during domestication means that domestic cats tend to interbreed freely with wild relatives,[32] which distinguishes them from other domesticated animals. [citation needed] Fully domesticated house cats also often interbreed with fe ral F. atus populations. [25] However, several natural behaviors and characteristics of wildcats may have pre-adapted them for domestication as pets. [39] These traits include their small size, social nature, obvious body language, love of play, and relatively high intelligence;[40]:12ââ¬â17 they may also have an inborn tendency towards tameness. [39] There are two main theories about how cats were domesticated. In one, people deliberately tamed cats in a process of artificial selection, as they were useful predators of vermin. 41] However, this has been criticized as implausible, because there may have been little reward for such an effort: Cats generally do not carry out commands and, although they do eat rodents, other species such as ferrets or terriers may be better at controlling these pests. [4] The alternative idea is that cats were simply tolerated by people and gradually diverged from their wild relatives through natural selection, as they adapted to hunting the vermin found around humans in towns and villages.

Human Development Essay
Human development is marked by different stages and milestones over the lifespan. It is expressed over three domains: physical, cognitive and socio/emotional. While human physical and cognitive development is universal, socio/emotional definitions and development vary from culture to culture. The various stages of human development include the prenatal period, infancy, toddler hood, early childhood, middle childhood, adolescence, young adulthood, middle adulthood and late adulthood. Each stage is marked by milestones in physical, cognitive, and socio/emotional development. The theorist that investigated about middle adulthood was Erik Erickson. Erikson observed that middle-age is when we tend to be occupied with creative and meaningful work and with issues surrounding our family. Also, middle adulthood is when we can expect to ââ¬Å"be in charge,â⬠the role weââ¬â¢ve longer envied. The significant task is to perpetuate culture and transmit values of the culture through the family and working to establish a stable environment. Strength comes through care of others and production of something that contributes to the betterment of society, which Erikson calls generativity, so when individual in this stage they often fear inactivity and meaninglessness. As children leave home, or relationships or goals change, they may be faced with major life changesââ¬âthe mid-life crisisââ¬âand struggle with finding new meanings and purposes. If adults do not n get through this stage successfully, they become self-absorbed and stagnate. The main features of midlife refer to the transformation and progress on physical, cognitive/intellect and social domains. Changes are also evident on expertise and personality. Physical change is the most gradual. Such changes include, atrophy of muscles, slower metabolism, skin elasticity and dryness, wrinkles, slow growth of nail and hair and baldness. These changes also facilitate the decrease in height, increase in weight and decrease in bone density, strength and immunity, vision and hearing and decrease in kidney function and cardiac output. The greatest lost in this domain since physical factors are the primary source of sensory and motor functioning. The changes in physical attributes are generally characterized by menopause in women and andropause in men. Menopause is when the body stops ovulating and producing estrogen and gradual decline in testosterone levels. These physical changes are emphasized of the double-standard of aging. Men become more distinguished and women become old. Cognitive changes has to do with the way humans perceive and experience the world and deals with issues like memory, thinking and decision-making processes and concept comprehension. During middle adulthood, humans are experts at problem solving, although they begin to experience some signs of decline with speed in processing and recall. The lost mainly focuses the ability to perform tasks unlike the agility that they could exert when they are much younger. Many are losing confidence on performing the same task because their IQ or memory wonââ¬â¢t allow them to do so. Social changes are wherein the individuals became more aware of his being, his worth and his surrounding. They become more aware of their own mortality, the passing time and the seriousness of the physical decline. The gain is the opportunity to identify you with others and contribute time to the community. Social changes has to do with how an individual is able to handle emotions, relationships, social situations, and the various roles demanded of them by society. Some aspect of Socio/Emotional standards, such as social expectations, relationships, and roles vary from culture to culture. The implication of middle adulthood to social work practice basically refers to the familiarity of the social worker to the journey of the service-users towards reaching that stage of life. The social worker may find difficulty in dealing with them especially when he or she has no idea where his or her clientsââ¬â¢ concerns and issues are coming from. Their assistance would be feasible if they can recognize the role that culture plays on the process of. Middle adulthood is met with the psychological and emotional challenges of facing the mid-life crisis, and a life analysis and inventory is taken. During this stage of lifespan, adults encounter changing roles that families face. Firstly in terms of career and work. Adults most often choose to go to college for work-related purposes. Many employers require workers to attain certain levels of education in order to qualify for promotions due to globalization. some adults may change career fearing the consequence of losing jobs while Others go to college to learn new skills in preparation for another career. Some, adults may also return to college simply for personal enrichment. ââ¬Å"The role of work , whether one works in a full time career, part time job or as a homemaker, is central during middle adulthoodâ⬠(Santrock,2009,p490). As adults reach their peak position in earning, they are saddled with multiple financial burdens including rent, mortgage, medical bills, and children tuition. These competing demands hinder the middle adulthood to further to career progress. They decide whether to change jobs or career, or rebalance family and work or plan for retirement. Having some knowledge about human lifespan development is beneficial for many reasons. It increases self-awareness and understanding, which helps with life planning. If a female is aware of the stages of her physical development, for example, she will know that her natural childbearing years are limited. If she wants to have children, she can use family planning to make choices about her education, career and mate to support this goal. Additionally, this knowledge can be helpful for improving relationships and interpersonal communication and resolving conflicts.

Internet Banking Essay
Therefore, since U. K. consumers have used to browsing and shopping online, there are factors that U. K. mobile carriers should pay attention. The factors are to find and collaborate with mobile commerce providers so that they can boost the M-Commerce traffic and thus, revenue. The potential of conducting mobile commerce in the U. K. also bases on the facts that the country has many mobile subscribers. According to International Telecommunication Union (2006), U. K. has 61 million of mobile customers as of January 2006. If 20% of the customers (15 million users) are active subscribers of M-commerce with average spending $100 per month. Therefore, the market for mobile commerce in the UK is $18 billion per year. The condition highlight that mobile commerce is attractive service that mobile service providers like Vodafone must develop by collaborating with merchants and content providers (cp) that build the mobile commerce applications. The development of m-commerce is also backed up by the recent development on 3G (third generation) mobile technology that gives opportunity for subscribers to have faster access to browse internet via mobile phones and conduct m-commerce transaction. British Telecom, for example, estimates that in 2002 they have about 150,000 customers of broadband services that is potential to be the active users of mobile commerce (Verdin, 2002) Recent progress and invention in mobile and wireless technologies has caused the shifting paradigm shift from desktop computers to mobile devices. Recently, it is usual to find consumers using their Personal Digital Assistants (PDAs), smart phones, and notebooks that strengthen the facts that business has gone mobile so that the consumers can do all things over wireless gadgets the same with doing by desktop computer (Intel, 2004). The improvement in mobile devices capability also attracts customers to buy new phones and new customers segment that also target teenagers. This condition becomes issues for telecommunication companies and content providers to develop new killing applications besides voice communication that will increase the corporate revenue. The new application is data communication that comes in many forms. Concerning data communications, this paper has discussed several issues/challenges and opportunities in UK mobile telephone industry. To be specific, the point of discussion is about the development of mobile commerce (M-Commerce) that takes advantages of increasing number of mobile users and the development of computer technology.

Telecommunications and Networking Article Example | Topics and Well Written Essays - 3250 words
Telecommunications and Networking - Article Example The rise of ICT and electronics brought tremendous advancement to communications technology which had grown from the ordinary Morse code, to simple telephony, and recently through visual telecommunication, and finally to the advent of wireless systems. The impact of this progress hastened the speed and the convenience of delivering and receiving valuable information with vividness and precision. Modern society has become so agile with the fast pace of life, businesses, and the need for mobile technologies has also increased. Developments cope with these needs and telecommunications became mobile with cellular pagers, cellular phones, and recently with mobile videophones. Surely telecommunications is accessible wherever you are in the world. If this technology did exist during WWII, Pearl Harbor tragedy could not have happened. The pace of development along the field of ICT and telecommunication seems so fast that new technologies emerged and changes in monthly basis. Ideas keep coming out every single day and before you know it, what is in today is pass' by the end of the semester. Take for example the emergence of wireless communication technologies. Before we know it the once popular analog mobile phones has gone so far to integrate computing and mobile internet access in just a span of three generations. That is a lot of time if you think of it but to appreciate the progress its better understood in terms of what had changed so far since the first cellular communication device was introduced. We can even trace back our discussion of the history of wireless communications from 0G or Zero generations when telephone systems was still operator assisted with very limited channels. But we have to begin our exploration from First generation (1G) to third generations (3G) of modern mobile communications, a gro wing family of wireless technology. The First Generation (1G) "The big boom in mobile phone service really began with the introduction of analog cellular service called AMPS (Analog Mobile Phone Service)" (Shepler, 2005). The first generation technologies of wireless communications are analog cellular phones. Based on record the 1G era covers the 1980s. The first mobile phone systems, called as "cellular mobile radio telephone" used analog radio signals which are transmitted via a less developed networks of repeaters such as those used by amateur radio operators.. Analog signals are continuous electrical signals that vary in time and variations follow that of the original non-electric signal to make them analogous hence the name analog (Net Tel Information Center, 2004). In analog technologies, the voice signals are transmitted via a base carrier in a form of an alternating current which frequency is changed and varied to match the original signal, amplified, then transmitted via the networks. This system is still used in some landline telephon es and radio broadcasts today. Among the first 1G systems introduced was in 1979, with Japan's Nippon Telegraph and Telephone Corporation, Sweden, Norway, Denmark, and Finland's Nordic Mobile Telephone (MBT) system launched in 1981, and the Total Access Communication System (TACS), deployed in the United Kingdom in 1983 (Britannica Online, 2008). The Second Generation (2G) The birth of digital

Leadership theories Research Paper Example | Topics and Well Written Essays - 2000 words
Leadership theories - Research Paper Example Leadership is ever green immortal and probably the most talked about topic. Perhaps the reason of its immortality is its relevance to our lives not only professional or business but personal and social life as well.It will not be an overstatement to say that leadership is that life-enriching and vital experiences which is crucial for our existence. Its scope is very vast which cannot be restricted to a single task, job, role or a certain organizational level. In this paper I will discuss in detail what is leadership? Different accepted styles of leadership, theories of leadership their merits and demerits and what was the need for the new theory to evaluate. It will basically be a comparative study of the two theories of leadership. What is leadership? Leadership is very vital and its importance is widely accepted. In order to understand fully different theories of leadership we first need to have a clear picture of what leadership is all about. It may sound simple but in fact leader ship is a very complex and complicated social process which depends not only the ways of thinking, vision, creativity, knowledge, skills characteristics and values of the leader but also the followers. Leadership is not all about aura and charisma of a person but a good leader is one who can see the clear picture of the present understands itââ¬â¢s various aspects and through his vision can guide its followers to the bright future. Good leadership (V.Gallos, 2008)is emotional; it compels drives and motivates you to achieve something. It is a continuous process of building and maintaining the relationship between the follower and the leader. In its spirit it is multidimensional which encompasses different skills, vision, process, map, issues, organization levels, cultures, policies, practices and issues. A good leader has to pass the test of time banking on the strengths and minimizing weaknesses while materializing the opportunities and avoiding the threats in the environment wit hout overreliance on any single person or process. Leadership Theories In the twentieth century theories about leadership started to evolve. Classical theories of leadership were based on traits of the leaders such remained the case for about thirty years and then it evolved to behavioral theory of leadership. There are basically six types of theories of leadership.
