The Meaning Of Revolution By Hannah Arendt Summary

Hannah Arendt’s chapter titled â€Å"The Meaning of Revolution† is used as a means to describe the origins and basis of modern revolution and how the social question impacted its meaning into modern times. She first addresses existing revolutions as ones that attempt to overthrow a tyrannical power such as a king or a Machiavellian prince who refuses to distribute wealth amongst his people. Thus, she finds that people in pre-modern times revolted against authority because of their lack of wealth. It is here that Arendt makes the distinction between revolutions by citing America as the first nation to address the â€Å"social question† in that they felt strongly that poverty was not a natural human condition. This in turn prompted American society to†¦show more content†¦On the contrary, Arendt continues her study on modern revolution by affirming that modern revolution has used both freedom and liberation as a means to describe it where the meanings of t he two ideas can become rather ambiguous. However, the governing principles of revolution are used in a way that instills people with a sense of freedom and the willingness to establish something new. These feelings as discussed above are the driving forces of revolution according to Arendt. The third section of Arendt’s study on revolution describes the political genius of Machiavelli and the efforts he made to describe the basis of all revolution. Arendt describes how the word revolution was absent from the medieval world. It is here the Machiavelli first describes the means to overthrow rulers without the inclusion of Christian teachings. He accomplishes this by describing how political figures must learn to be not good in order to create an enduring reign as seen in The Prince. He also enforces the need for violence in politics as the direct consequence of â€Å"the twofold perplexity† which consists of a new beginning and the new foundations of society. However di fficult it may have been to describe, Machiavelli sought to instill the morals and values of freedom that society once had before the oppressive reign of principalities. Arendt concludes her third section by claiming that the medieval world knew ofShow MoreRelatedStephen P. Robbins Timothy A.

The New Meaning Of Airline Packing - 1370 Words

The New Meaning to Airline Packing Before 9/11 when Americans boarded an airplane, the only worry that crossed their minds could have been hijackers holding the airplane, the crew, and the passengers for some kind of ransom, or something going wrong with the airplane itself. After 9/11, we are now seeing a new kind of hijacker; terrorists who use the airplanes themselves as weapons against the people they hate. They run the airplanes into buildings to kill as many people they can with one attempt. This paper will take a look at what the government did in the days after 9/11 to put into place a defense against terrorists. From the Aviation and Transportation Act that was passed in November of 2001, Arming Pilots Against Terrorism Act that†¦show more content†¦This act required airlines to use stronger materials in the construction of cock pit doors, heavier locks, and video monitors for pilots to view what is happening in the cabin. Putting in wireless devices for the flight crew to notify the cockpit of any problems. Just weeks after this act was passed by Congress the airline Jet Blue had these requirements in every airplane they own. Putting crew and passengers safety before their profit. This act also gave to the Under Secretary of Transportation the job recruiting, training, and providing weapons for air marshals for each flight. As an elite group, highly trained, the air marshals will set with the passengers and have the advantage of knowing what is going on inside the cabin at all times. Carol Hallett, head of the Airline Transportation Association said â€Å"The wisest investment in improving security is hiring more air marshals because they are highly trained to provide professional protection.† (Renna, 2003) This protection is costing the airlines approximately $3,000 per air marshal, per flight. Requiring two air marshals in each plane. Part of the Aviation and Transportation Security Act gave the Under Secretary of Transportation the job to recruit, train, and air pilots using similar training programs that were used for air marshals. The program for the pilots is done on a volunteer basis program only. In

Privatized School Systems Free Essays

Our society, as a whole, has been heading toward a decentralized system of conducting its affairs. Large corporations have been getting larger , meanwhile governments have been giving up increasing amounts of their control. This decentralization has affected even former mainstays of government control, such as phone and power companies. We will write a custom essay sample on Privatized School Systems or any similar topic only for you Order Now As decentralization becomes more of a reality, there has been a great deal of debate over what controls the government should maintain or relinquish. The public school system has long been a source of frustration. Many feel the schools would be run more efficiently and with better results if privately run companies were to take over. They feel that with the existing large, encumbering bureaucracy, the government is simply unable to provide the proper base that is necessary to support a successful school system. The proponents of privatized school systems have long maintained that governments are not as knowledgeable about individual school environments as those who and they have to manage many schools, whereas the owners of a specific private subsidized school would be well informed about the school’s circumstances and can concentrate on that school alone. They say that the governments role should become that of regulator, not schoolmaster, and that since the private schools do not face the political constraints that the municipal governments face,they would be more able to adapt to change. Since the operation of public schools is more bureaucratic and centralized than private subsidized schools, it is expected to inhibit rather than promote educational innovation. Private schools, being less bureaucratic and more decentralized, are expected to be more efficient organizations and to have a better perspective than their public school counterparts. They are also expected to provide a greater incentive and opportunity to come up with more innovative programs than public schools in order to stay competitive. Bureaucracy is expected to hinder initiative and efficiency, whereas the private sector in general is expected to be more dynamic and responsive because of their need to stay competitive. It is hoped that this competitiveness will foster innovation. On the other side of the debate is the group that favors continued government control over the school system. They argue that privatizing the schools would lead to a decreased focus on the needs of the children with an increased emphasis placed on the bottom line. They maintain that the companies taking over for the government would focus their attention more on cutting corners to make larger profits rather than on the education of children. With continued government control over the school system, there will remain a stability that is necessary to insure a full and equal educational opportunity for all. Having the education system privatized would create inequalities in the method that education would be provided. Those who oppose privatization agree that not only would municipal control maintain stability, but would also ensure fair and equal teatment for all. The same would not hold true if the schools were placed in private hands. Schools that do not make a profit along with teachers that are no longer needed would simply let go in order to save money or maintain profits. I can see that there are several benefits on both sides. The economic benefits are obviously in favor of a decentralized school structure. There be no bureaucracy to wade through to make the simplest decisions, in the system would allow teachers to make important ground level decisions as they see fit. This increased efficiency includes many benefits, but with what cost? What about the special needs children, or the under privileged, will the private companies take care of them? What happens when these companies don’t make enough money on a school, will they close it down? The children whose schools have been closed will have to travel further and further just to get to school, if they even go. Maybe there should just be mega-schools were ten schools are combined into one, all to save the managing company money. With government control, there may not be efficiency but there is some stability. That is the important thing. Companies can open and close their doors in a day, but schools are more important than companies. Education is the key to our futures, can we afford to gamble with what is a stake? The government must become more efficient at doing its job in managing our schools, and business has proven itself to be efficient. Maybe there is a way to combine the two and receive the best of both worlds. How to cite Privatized School Systems, Papers

Ageism and moral exclusion of older people - MyAssignmenthelp.com

Question: Discuss about the Ageism and moral exclusion of older people. Answer: Aging is a process in which people tend to grow old. The term is applicable to all the livings organisms on earth and humans in specific. In an extensive explanation, ageing also refers to the cease of cell division which leads to the death of the cell and it is applicable to the species in a population. In humans specifically, ageing refers to the changes that take place in human body over time which includes; social changes, psychological and physical changes. Ageing affects the reaction time of an individual although knowledge and wisdom may increase with the increase in age. Ageing is considered as the major culprit of risk factors and diseases that affects the aged people. All over the world around 150 thousand people die every day due to old age related diseases. Although, the real cause of ageing is not known. The consistent damage to the DNA and the inability of the systems of the body to recover from such damages leads to ageing (Kalsy-Lillico et al. 2012, 359-92). This stud y typically emphasizes on the theological and pastoral issues of ageing relating to dementia. The study involves an aged person of 70 years who is experiencing dementia. Due to ageing the several physical impacts and psycho-social impacts and experiences are highlighted. His personal experiences and the pastoral strategies by which a dementia affected person can be helped to recover. Personal experience of ageing can be described as an ageing process from a personal perspective. The personal experience of ageing can be explained through a multidimensional approach. There exists three different dimensions of ageing, the first dimension is physical decline such as the decline in health and vitality. The second dimension is the continuous personal development and growth. The last and the final dimension is the losses in relation to the social domain, which can be elaborated as the loss of respect and need by the other people. In the first dimension of physical decline, the aged people faces the decline in health due to the ageing issues. Several serious ailments like heart diseases, kidney diseases, eye sight and hearing related problems decreases the vitality of a person which both slows and degrades the health of an aged person (Suzman et al. 2015, 484-486). In the second dimension of personal development and growth, the aged person continuously gains knowledge an d wisdom as the time progresses. This is one of the positive impacts of ageing which brings respect for that particular aged person. There is no doubt that aged people although lacks the mobility and the vitality, but still they possess the vast amount of knowledge which benefits the other persons around. The third dimension of loss of social domain is considered as one of the biggest negative impacts of ageing. The aged person lacking the vitality and deteriorating physical health condition often remains isolated and neglected from his/her family. Due to this reason the aged people feel they are less respected and a negative psychological tendencies develop within their minds (Schwanen et al. 2012, 1291-1295). This however later leads to anxiety and depression. When people age they get an idea that the life is coming to an end. There are several challenges that they face when start to age and is common with all the humans irrespective of gender, culture, nationality and physique. The personal experience so ageing is discussed as under. Mortality As people grow old and age, they get confronted with the thoughts of anxiety and these thoughts are differing in individuals that are either parent or a religious people. From a parents perspectives, I can say whether a person is single or couple, always conscious about their progeny and that they should live on. The felling is same for the non-biologicals as they know that life will move on. The children and the grandchildren provide a sort of merriment for older people and gives a feeling of happiness and complete in all the hardships of ageing. The singles and couples that do not have the children or the progeny suffer from the pain that they are not leaving any next generation, although they had once decided not to have kids. Again when it comes to religious aspects of ageing, I think the religious beliefs and spiritual life both act to reduce the fears and depressions of existential pain and mortality. The belief of presence of life after life along with the spirituality acts as a guidance and a meaning to the life of the aged people. The aged people also find the eternal peace and a spiritual connection with the other aged people that share the same belief (Romero-Ortuno, and Rose 2012, 684-689). Dependency When people age they need the much needed support systems and it becomes an important part of our later life. Once these people used to strong and independent once but now they depend on their family and the friends. Individuals that had maintained a good relationship with his family and his friends always in a better situation than the other aged people. They may have moved away from our loved ones and the family members. However, the feeling of connection with the loved ones makes us feel supported and connected. Although, there are certain aged people that abandon their family or get abandoned by their family. For such people, emotional pain and regret are a common companion. Women and men stay better if they have created a group of friends around them that stay together like a family. The childless couples and singles experience a less painful life if they have a nested group of friends that have the similar interests. The aged people living in rural areas face more problem in co mparison to the one that live in the cities. This is the sole reason of the popularity of the assisted living facilities (Ruan 2015, 1-10). Midlife crisis- reaching the midlife stage does not result in the crisis situation as the period is anticipated. The aged people that once had experienced the sorrows and upheavals of life in their middle age of the remains prepared to the challenges that arise in future. Thus the previous challenges faced in the earlier part of the life result in better coping up and can be experienced just like another turning point in life. The survivors of major crisis like the political unrest, bankruptcy and natural disasters often tend to say they are confident enough to face any situation in future. The aged people who have experienced dead end relationships and failed marriages often view the midlife as a chance to start the life afresh (Bauer et al. 2015, 22-42). Ageism the prejudice related to ageing is present everywhere. Although it is seen everywhere that life expectancy is gradually increasing due to the advancement in science and medicine. However, according to me the present day youth and their obsession for fashion almost make the 50-year-old people just invisible. Discrimination is one of the major issues faced by the aged people due to the difference in religion, race, sexual preference. I think that the experiences gained over the years can be beneficial for an aged person to cope up with the discrimination. One important thing to note with ageing is the psychological effects of ageing on the people that used to emphasize more on their looks and physique. The reason is that later on these people suffer from the early incidence of ageing which includes loss of fertility, sagging skin, decreased stamina, virility. Sometimes people even try to reduce the impact of ageing through artificial procedures like cosmetic surgeries, usage of steroid s. This affects such aged people because once this image had brought them fame, success (Johnstone 2013, 27). Healthcare At a certain point, as people grow older they rely more on the healthcare. There are two different groups of people that suffer from the health issue. One is the person who knows the ailments that he is suffering, still the person is unable to move for treatment as because he is not financially strong enough. While the other type of person has financial support although does not know that he is suffering from any ailment (Roberts et al. 2013, 241-246). First person accounts of ageing- in the interview there were certain questions that were asked like: 1) what is the definition of successful ageing; 2) why to age successfully is important? 3) how the experiences of your life changed or impacted the ageing process? 4) provides the suggestions on how to age without major problems and any recommendation on the interventions needed for healthy life. The answers received from the respondents regarding the definition of successful ageing emphasized on the self-contentment and self-acceptance. According to the respondents successful ageing is like accepting the present stage of life. Staying away from the thoughts that makes us dwell in the past and regrets that we could have done this or done that (Reichstadt et al. 2010, 567-575). However, accepting the fact that the present scenario will not let us do it. This is the best way to make peace with the past. For some people this stage of live is a new found feeling. The second question was the definition of successful ageing and one of the response was successful ageing is a part of life and enjoying every bit of it is best part. It takes long time for a person to convince himself that the present condition of life is all that matters. The future is unpredictable and to live the present is first priority. The other responses are for the aged people that are active, they must know that they are growing old day by day. These active people are proactively enjoying the life to its full and are adventurous and fun loving. These people love to go for an adventure and not the type who would be unwilling to stay at home. The other responses are the social interaction that the aged people goes through is always considered as a learning process. Aged people can gain knowledge form other people life and can incorporate the learning in their own life (Reichstadt et al. 2010, 567-575). Pastoral strategies There was a perception that, aged people who are suffering from dementia and are unable to communicate effectively can recover from this condition if they start to participate in the spiritual practices. It was though that aged people will spring to life when they will be asked to say the lords prayer and would help them to perform the normal everyday communication with ease. However, the truth is that people suffering from dementia are not able to perceive the intellectual complexities associated with the spiritual practice. The people who are suffering from dementia experience the damage to the brains that reduce the intellectual and cognitive abilities and extensive memory loss. In dementia people are affected to such an extent that they lose the ability to recognise themselves and even others. During the study, the author while ministering had to adopt certain postures. This posture does not mean a different set of attitude of mind. This means that during ministering the author h ad to kneel down or bow down in front of the person (Swinton 2014, 160-172). This posture generally replicates the posture of worship and the people affected with dementia are able to recognise the rituals of worship. The study emphasizes that the negative effects of dementia are many and it includes inability to communicate properly, social interactions, patterns in behaviour and the ability to take care of oneself. The majority of the repercussions fall not only on the family and friends but also on the care givers. The person suffering from dementia lose the capability of personal reflection and are left alone to make what they want to make out of their own understanding and perception (Duin 2013, 101-112). The pastorals and the chaplains care givers have the exclusive responsibility to work for the people and the families affected with dementia. One in four people are not ready to accept the fact that they are affected with dementia. However, from the study it was found one of t he chaplains to be saying that what is the needs in providing the dementia affected people with the pastoral and care. Because the concepts of theology are beyond the understanding of the dementia affected people. Aged people affected with dementia are not in a condition to understand the idea behind spirituality and the existence of god. It has been seen that people suffering from dementia are often stigmatized and ignored and the Christian theology states that every human must be treated with respect (Hudson 2016, 50-67). Not because that person possesses the natural rights, but due to the fact that god resides in every human Thus, for such people, providing them with the self-help books and pastoral care are not enough for the recovery of the people suffering from dementia. Christian theology clearly states that no person is self-made and need other person to point out the weaknesses. Both the first and the final word that can solve all major problems related to dementia is the w ord love. The person suffering from dementia need the care and love from his neighbouring people, friends and families (Hudson 2016, 50-67). Therefore, from the above discussion it can be concluded that in aged people the health issues arise with continuous ageing. When people age there are certain changes in the body that a person must get accustomed with to reduce the psychological impacts. The people who to some more extent rely on their self-image during their old age, must accept the fact that they no longer possess such health conditions in the present scenario. However, according to some of the interview questions asked relating to ageing, it was later inferred that a majority of the people are happy with the way they have experienced issues of ageing. The pastoral and theological issues relating to ageing and dementia reveal that, persons with dementia almost always forget to remember the existence of god and lack the spirituality. Thus, the care provided to such people must be through love and care. Reference Bauer, Esther K. "Masculinity in Crisis: Aging Men in Thomas Mann's Der Tod in Venedig and Max Frisch's Homo faber."

Anti-Federalism essays

Anti-Federalism essays The adoption of the U.S. Constitution created a centralized authority giving a great amount of power to the federal government. I think that the governments powers should be reduced and more equally divided among its branches. With such things we could have specific limitations on the government's taxation and commerce powers as well as many other things that would make our society better for the people. I feel that the Articles of Confederation work, they just need amending. This new found liberty is something that shouldn't be given up on so easily. At the Constitutional convention in which George Washington was elected President many key people were absent from the meeting; Thomas Jefferson and John Adams were away on foreign affairs and Patrick Henry refused to attend the meeting because he "smelt a rat". Patrick Henry's suspections were correct being that James Madison who had been behind the formation of the meeting had in mind the creation of a powerful central government and the subversion of the authority of the state legislatures. With the meeting being held without the presents of some of the country's major political leaders, decisions were not made to their greatest potential. In their absence some ideas were proposed such as Madison's idea that called for the near annihilation of the State legislatures and the creation of an implied empire. Other ideas came about like Alexander Hamilton's statement that the British government was above all others and had a plan to appoint lifetime executive officials - a Monarchy. The reason most Anti-Federalists oppose to the Constitution is that the republic must remain in the states, it must be geographically small in order to meet the needs of the people. With such a large demographic, the interest of the people would be too diverse and should be kept divided for individual control. SUch large districs ...

Killer Whale (Orca) Facts

Killer Whale (Orca) Facts With their striking black and white markings and prevalence at marine parks, the killer whale, also known as the orca or Orcinus orca, is probably one of the most easily-recognized cetacean species. The largest of the dolphin species, orcas live in oceans and seas around the world and can grow to 32 feet long and weigh up to six tons. The name killer whale originated with whalers, who called the species whale killer because of its tendency to prey on whales along with other species such as pinnipeds and fish. Over time, perhaps because of the whales tenacity and ferocity in hunting, the name was switched to killer whale. Fast Facts: Killer Whales (Orcas) Scientific Name: Orcinus orcaCommon Name(s): Killer whale, orca, blackfish, grampusBasic Animal Group:  Mammal  Ã‚  Size:16–26 feetWeight: 3–6 tonsLifespan: 29–60 yearsDiet:  CarnivoreHabitat:  All oceans and most seas with a preference for northern latitudesPopulation:  50,000Conservation  Status:  Data Deficient Description Killer whales, or orcas, are the largest member of the Delphinidae- the family of cetaceans known as the dolphins. Dolphins are a type of toothed whale, and members of the Delphinidae family share several characteristics- they have cone-shaped teeth, streamlined bodies, a pronounced beak (which is less pronounced in orcas), and one blowhole, rather than the two blowholes found in baleen whales. Male killer whales can grow to a maximum length of 32 feet, while females can grow to 27 feet in length. Males weigh up to six tons while females can weigh as little as three tons. An identifying characteristic of killer whales is their tall, dark dorsal fin, which is much larger in males- a males dorsal fin can reach a height of six feet, while a females dorsal fin can reach a maximum height of about three feet. Males also have larger pectoral fins and tail flukes. All killer whales have teeth on both their top and bottom jaws- 48 to 52 teeth in total. These teeth can be up to 4 inches long. Although toothed whales have teeth, they dont chew their food- they use their teeth for capturing and tearing food. Young killers whales get their first teeth at 2 to 4 months of age. Researchers identify individual killer whales by the size and shape of their dorsal fins, the shape of the saddle-shaped, light patch behind the dorsal fin, and scars or marks on their dorsal fins or bodies. Identifying and cataloging whales based on natural markings and characteristics is a type of research called photo-identification. Photo-identification allows researchers to learn about the life histories, distribution, and behavior of individual whales, and more about species behavior and abundance as a whole.   wildestanimal/Getty Images Habitat and Range Killer whales are often described as the most cosmopolitan of all cetaceans. They can be found in all oceans of the world, and not just in the open ocean- near shore, at the entrance to rivers, in semi-enclosed seas, near the equator, and in polar regions covered with ice. In the United States, orcas are most commonly found in the Pacific Northwest and Alaska. Diet Killer whales are at the top of the food chain and have very diverse diets, feasting on fish, penguins, and marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches long. They are known to grab seals right off the ice. They also eat fish, squid, and seabirds. Gerard Soury/Getty Images Behavior Killer whales may work in pods to hunt their prey and have a number of interesting techniques to hunt prey, which includes working together to create waves to wash seals off ice floes and sliding onto beaches to capture prey. Killer whales use a variety of sounds for communicating, socializing and finding prey. These sounds include clicks, pulsed calls, and whistles. Their sounds are in the range of 0.1 kHz to about 40 kHz. Clicks are primarily used for echolocation, although they may also be used for communication. The pulsed calls of killer whales sound like squeaks and squawks and appear to be used for communication and socialization. They can produce sounds very rapidly- at a rate of up to 5,000 clicks per second. You can hear killer whale calls here on the Discovery of Sound in the Sea website. Different populations of killer whales make different vocalizations, and different pods within these populations may even have their own ​dialect. Some researchers can distinguish individual pods, and even matrilines (the line of relationship that can be traced from one mother to her offspring), just by their ​calls. Danita Delimont/Getty Images Reproduction and Offspring Killer whales reproduce slowly: Mothers give birth to a single baby about every three to 10 years, and pregnancy lasts for 17 months. Babies nurse for up to two years. Adult orcas generally help mothers to care for their young. While young orcas may separate from their birth pod as adults, many stay with the same pod throughout their lives. Male and female orcas. Kerstin Meyer / Getty Images Threats Orcas, like other cetaceans, are threatened by a range of human activities including noise, hunting, and habitat disturbance. Other threats faced by killer whales include pollution (orcas can carry chemicals such as PCBs, DDTs and flame retardants that can affect the immune and reproductive systems), ship strikes, reduction of prey due to overfishing, and loss of habitat, entanglement, ship strikes, irresponsible whale watching, and noise in the habitat, which can affect the ability to communicate and find prey. Conservation Status The International Union for Conservation of Nature had, for years, described orcas a conservation dependent. They changed that assessment to data deficient in 2008 to recognize the probability that different species of killer whales experience different levels of threat. Species Killer whales were long considered one species- Orcinus orca, but now it appears that there are several species (or at least, subspecies- researchers are still figuring this out) of orcas. As researchers learn more about orcas, they have proposed separating the whales into different species or subspecies based on genetics, diet, size, vocalizations, location and physical appearance. In the Southern Hemisphere, proposed species include those referred to as Type A (Antarctic), large type B (pack ice killer whale), small Type B (Gerlache killer whale), Type C (Ross Sea killer whale), and Type D (Subantarctic killer whale). In the Northern Hemisphere, proposed types include resident killer whales, Biggs (transient) killer whales, offshore killer whales, and Type 1 and 2 Eastern North Atlantic killer whales.   Determining species of killer whales is important not only in gaining information about the whales but in protecting them- it is difficult to determine the abundance of killer whales without even knowing how many species there are. Killer Whales and Humans According to Whale and Dolphin Conservation, there were 45 killer whales in captivity as of April 2013. Due to protection in the U.S. and restrictions on trade, most parks now obtain their killer whales from captive breeding programs. This practice has even been controversial enough that SeaWorld stated in 2016 that it would stop breeding orcas.  While the viewing of captive orcas has likely inspired thousands of budding marine biologists and helped scientists learn more about the species, it is a controversial practice due to the potential effects on the whales health and ability to socialize naturally.
