The Price People Pay For Using New Technology Is Their Freedom And

The Price People Pay For Using New Technology Is Their Freedom And The Price People Pay For Using New Technology Is Their Freedom And Personal Relationships Describe â€" Essay Example > Currently in the western societies more people have been employed collecting, distributing and managing information than in other careers. Millions of miles of wire, optical fibre, and air waves connect people, their computers and many other information handling devices together. We are living in a society that can be labeled as an information society (Joinson et al, 2010). The challenge and question that is facing many people is whether this is the society that we want? Leaving the home without mobile phones or no being in position to maintain constant communication using the Internet is unimaginable in the current world and very unbearable to many people. Family, colleagues, and friends expect to contact us any time despite of the distance or time between us. People check mail regularly as well as respond to text messages almost instantly (Wang Wellman, 2010). Technology has come with the price we have to pay in terms of personal relationships and freedom. Constant communicatio n using mobile devices has been criticized for disconnecting people from those who are physically around them. Many people complain they do not get visits from relatives with the coming of mobile phones. People prefer to meet in social places and call to ask about how others are doing instead of visiting them. Groups have been started on social media where important things can be discussed without face to face contact. Personal relationships have suffered where spouses pick up quarrels and accuse each other of spending more times in social media sites instead of engaging in meaningful conversations for the purpose of bonding and being intimate with each other. In many social places where people could engage in conservations with strangers it is no longer the same. People prefer indulge with their phones and chat to friends or strangers online instead of interacting with those people they can see (Christofides, Muise Desmarais, 2012). Pastors have complained of people who get enga ged with their mobile phones when the church service is still going on. In many places of worship there is always a polite notice asking people to switch off their mobile phones when getting into these places. Personal relationships can be hurt by new technology when individuals do not apportion their time properly and make the other person feel ignored and neglected. New technology can be used for increasing interaction or a source of distraction when one is not interested in engaging with the person close to him. Personal relationships suffer because of constant interference and distractions from many quarters. Breakages in relationships have increased due to interference of third parties and providing of unsolicited advice by ‘social media experts’ (Wang Wellman, 2010). People cannot enjoy an intimate conservation without someone getting suspicious or even recording if he or her things what is saying is funny. Private information is leaked in social media forums causing he artaches and divorces. People have to be extra careful and those who become careless are severely punished through shaming and judgment. Embarrassing vides, texts, chats and emails have been produced as evidence for existence relationships when one party was denying. Parents are finding it hard to relate with their children who take upon themselves to copy many things that they witness on the internet. The internet and coming of mobile devices has changed the way people relate since so much information is available on the internet. One can rather search for information on the internet than meeting up with friends to learn about something he is not familiar with (Scherer, Craddock Mackeogh, 2011). Policymakers, researchers journalists, and popular pundits often note that digital technologies have the ability of disrupting personal relationships as well as delivering uninvited content hence the term ‘friendly spam’ from relatives and friends where one is bombarded with forwarded messages that someone believes will interest them. Experts in child development are worried that phones together with personal computer devices distract parents from their children and vice versa and hence preventing engagement into nurturing conversations (Wang Wellman, 2010). Technology enables children to access violent video games, pornography and engage in cyber-bullying as well as other forms of online harassment. Child development is interfered with. The way children relate with their parents change.

The California Gold Rush Essay - 905 Words

The California Gold Rush nbsp;nbsp;nbsp;nbsp;nbsp;The California Gold Rush of 1849 is one of the most interesting and exiting events of the United States. From the wild stories of men striking it big, to the heart wrenching tales of people losing everything, these are what make it so alluring. There are many aspects of the California Gold Rush; effects on California; individual stories of struggle; and effects on the United States as a young country looking for stability. nbsp;nbsp;nbsp;nbsp;nbsp;San Francisco was a small town of a few hundred people in 1840, but by 1850 it was a huge city whose economy was injected with gold money. This rapid growth and development was brought on by an accidental discovery by James Marshall.†¦show more content†¦The economy of California is still a major risk taking economy, as it was back in the days of the Gold Rush. Computer companies start and go broke everyday in silicon-valley, producers spend millions of dollars on movies, sometimes hitting it big, and other times going bust. California has gained many of its traits and characteristics from the Gold Rush of 1849, shaping into what it is today. nbsp;nbsp;nbsp;nbsp;nbsp;What effects did the Gold Rush have on people? Some became forever rich, and some lost everything. In 1849, California was a rather uncivilized place, especially San Francisco. Miner’s came from every where to try to find their fortune, but most fortunes weren’t made mining gold, they were made because of mining. Sam Brannan was one such man who made his fortune this way. Brannan bought every shovel, pan, and every other mining related tool he could in the region. A twenty-cent metal pan now became a fifteen-dollar pan, and the only place to buy them was from Sam Bannan. Levi Strauss, a tailor who happened to have very popular canvas pants made his fortune from the Gold Rush. Phillip Armour, of Armour Meat packing company, and John Studebaker just to name a couple more.

The Depression Of The Great Depression - 2071 Words

Paul Von Hindenburg appointed Adolf Hitler Chancellor on the 30th January 1933. The Depression did play a vital role in this, however other factors such as the Nazis propaganda, the resentment of the Weimar republic and the political situation of 1932-1933 also contributed to his success. Before the Great Depression, the Nazis gained 12 seats and 2.6% of the vote in the May election of 1928. Despite this, by July 1932, Hitler gained 230 seats and 37.3% of the vote in the Reichstag. This is a dramatic increase in popularity and support with much of this success due to the Great Depression. In October 1929, the American stock market crashed, plummeting the US into a disastrous economic depression known as the Wall Street Crash. US banks recalled their loans in order to pay off their debts, but German companies were unable to pay. German business began to close and millions lost their jobs, as Germany was so dependant on US loans in order to pay their reparations. The reality of the situation made a mockery of the weak, short-lived coalition governments in the Weimar constitution as it highlighted that Germany economic recovery was dependant on US loans and hence Germany was not independent. This enabled the extremist parties to claim they knew exactly how to solve this crisis and Hitler promised the public an authoritarian government in which he could achieve Autarky as well as jobs for the thirteen million people now unemployed.

The counselor’s thoughts and feelings in reaction to the client can be from the client themselves or events in the counselor’s own life. We will write a custom essay sample on Countertransference or any similar topic only for you Order Now Counselors should monitor their feelings while working with their clients. Counselors who are aware about their personal issues allow them to manage countertransference. They can feel empathy for their clients and compassion which is helpful in the therapeutic process. Therapists who manages countertransference recognizes their reactions and how it affects the therapy process. A counselor’s unresolved issue is the basis of countertransference. When a client talk about issues related to a therapist’s unresolved issue, the therapist tends to avoid the issue, according to Rosenberger and Hayes article. They will talk about the issue less in sessions with the client. Counselors dealing with unresolved issues pertaining to anger are more comfortable and anxious with angry clients. Therapists showing avoidance behaviors can cause clients to view them as being incompetent and untrustworthy. I agree with the findings in this article. Therapist avoidance also effects the working alliance, the therapist’s social influence, and the sessions. The article discusses what happens when a client brings up issues that are related to a therapist’s unresolved conflict. Managed countertransference results in improvement in insight, self-awareness, and resolution in therapy. A counselor’s ability to respond with empathy, genuineness, respect, acceptance, and caring influences the process of helping the client to identify their problems. Counselors must be able to pay attention to their clients. They must be able to set aside their own problems in order to work with client issues. Counselors in need of resolving unresolved conflicts may want to attempt to receive counseling themselves. How to cite Countertransference, Essay examples

The Declaration Of Language Essays - American Enlightenment

The Declaration of Language [WR122 paper, using Jefferson's "Declaration of Independence" as a model]-RJ The Declaration of Language When, in the course of human language, it becomes necessary for people to create or redefine, words or phrases to express an object or an action; and to assume, among society, the acceptance and usage of these words and their definitions, in one's own language, or idiolect. A decent respect to the opinions of mankind, requires that Americans should recognize slang adopted into language. We hold these truths to be self-evident: that language is expression of thought, in the form of speech or written symbols, that have agreed-upon meanings. That, many large speaking languages contain dialects, or other versions of languages within a community, that are different in some aspects of grammar, pronunciation, or vocabulary. That, because language is a form of one's own ideas and expression, everyone possesses his or her own individual language, or idiolect. That, not only does perception change language, but that language changes perception. That, through the course of history, idiolects have shaped dialects, which have shaped language, which in turn, have shaped concepts. Conservatives, indeed, will dictate that languages will follow a narrow path toward a standard language. And accordingly, expression will follow the rules and guidelines that limit thought, rather than the ability to rethink old vocabulary and enrich new ones. When we speak, write, learn, and think in a slowly evolving vocabulary, which does not adapt to the more rapid introduction of cultures, concepts, fashion, and technology, we must add new meaning to conventional vocabulary. Such has been the language of Conservative American English speakers and writers, who have discouraged the use of creative language and the use of dialects and idiolects. Many individuals have not noticed that new vocabulary is, at many times, adopted into one's language. A large number of slang words and phrases have been considered standard in today's daily speech. To prove this, let us claim a few of the many slang terms that have been adopted. Slang has been used, where other words seemed unfit to describe a thought or feeling: "Awesome." "Radical." "Cool." "Far Out" New words that were created to describe new technology: A "cellular" or mobile telephone. The "internet" or the computer and modem accessed information highway. "Electronic mail" or computer generated mail. A "beeper" or an electronic paging device. Metaphors, similes, and creativeness also create slang: A coward is a "chicken." Money is "bread." A "ride" is a car. One thousand dollars is a "grand." People eat "grub." Smoking marijuana is the same thing as smoking "weed" or "pot." A toilet is the "John." A toilet is the "can." A toilet is the "hole." A "Cop" is policeman. A "Pig" is also a policeman. If something is "bad" it is really "good." Those who are "plastered" are drunk. Those who are "hammered" are drunk. People who are driving too close behind another car are "tailgating." Slang, also evolves in the form of phrases: A person "Kicking Back," is relaxing. "Cut to the chase" or get to the point. Accept the consequences, or "face the music." "Two cents worth," or an opinion. "The whole nine yards" or everything. In the English language, we have petitioned for the use of slang in language. But our creative language has been considered meaningless to conservatives of standard English. Conservatives, who themselves use vocabulary that was at one time considered slang, are unfit to argue against it. Every language around the world adopts slang that, at one point, was considered nonstandard to the majority of the people. Slang is used to provide new shades of meaning. Slang is shared by introducing new concepts, just as new objects and ideas are shared. All vocabulary establishes its meaning through the acceptance of its concept into one's language. We must continue to express thoughts through one's choice of language, and accept them, as we would accept the importance of originality and creativity within individuals. We, therefore, the representatives of a linguistic society, do, in the Name, and by authority of speakers and writers of English, declare that slang refreshes language with new concepts, ideas, and interest; that slang allows language to evolve with society; that

Django Reinhardt Biography Essay Example

Django Reinhardt Biography Essay Example Django Reinhardt Biography Paper Django Reinhardt Biography Paper Django Reinhardt Django Reinhardt is known as one of the most talented jazz guitar soloist and as France’s most famous jazz performer. Django Reinhardt was born Jean-Baptiste Reinhardt on January 23, 1910 in Liverchies, Belgium. His parents were Jean-Eugene who was a musician and entertainer, and La Belle Laurence (also known as Negros because of her dark beauty) who was a dancer. He was born in the back of the caravan, which the Manouche gypsy family lived. His parents named him â€Å"Django† in his Romany name, which means â€Å"I awake† (Dregni, pp1-3). At a young age Reinhardt was introduced to music. Django’s father, Jean, was very talented and supported the family playing music on various instruments while his wife danced. On the back of the caravan where they lived, Jean had a stage where he and his wife performed musicals. Django’s first instrument was the violin which is very popular among gypsies because of the ease of transporting. He had no formal education in any school for music or reading: he was illiterate. His fathers as well as his Uncle Guiligou are credited with teaching him his early musical abilities. At the age of twelve he was given a banjo by a Manouche gypsy friend who saw how much he enjoyed music. Django played the banjo constantly which led to swollen bleeding fingertips. After witnessing how well her son played the banjo, Negro bought him a real guitar. Django, along with his cousin played the guitar on street corners and eventually into Paris (Dregni, pp 13-14) When Django was five years old his father left his mother to go live with his previous wife and children. Django would still see his father when they traveled and crossed paths. Soon after receiving the guitar, Django would venture to Porte de Clignancourt to the see his father and Uncle performing in a dance hall called Chez Clodoche. Django would hide under the tables and listen to the music. He was mostly interested in his Uncle Guiligou’s guitar playing and would watch as he played the chords. Once home, Django would repeat on his own guitar what was played that night in the dance hall. Eventually, his Uncle found him hiding and asked him to play a song on his guitar. He was so impressed with Django’s ability that he was soon playing with his father and Uncle every Saturday night at the Chez Clodoche. It was around this time as well that while playing in a cafe he was noticed by Vetese Guerino, an accordion player. Guerino hired Django to play for the large amount of ten francs a night (Dregni, pp 13-16). Django continued to play in dance halls from the age of 12 to 18 years old. His first record or recording was in 1928. Because of his illiteracy his name was spelled Jiango Renard on the record. It was during this time that he met Sophie Irma Ziegler, also a Manouche girl. They were both enchanted with each other and were together for two years until Django met the beautiful Florine Mayer. Django quickly left Sophie (Naguine), and eloped with Florine in the gypsy way. They were soon expecting their first child (Dregni, pp 31-36). It was during the pregnancy that an accident occurred that would forever change Django’s life. One night after returned home from working, fire broke out in the caravan that he and Florine lived. Both were badly burned and brought to the hospital. Django spent the next eighteen months in and out of the hospital, during which his wife gave birth to their baby boy named Lousson. Django almost lost his leg to amputation, but more importantly his left hand was severely burned. He lost the function of his ring and pinky finger leaving them permanently hooked which left only two fingers to play chords with. Unfortunately, his wife Florine left him when she realized how disabled he was, but Sophie, after hearing of his injuries came to his side. During his hospitalization his brother Joseph brought him a guitar and he practiced continually. Miraculously, he taught himself to play the chords with only two fingers. Django developed a new guitar playing technique that enabled him to play fast and not lose any musical ability (Dregni, p45-49). In 1934 while playing at The Hotel Cambridge tea dance he met Stephane Grappelli. During breaks he and Grappelli who played the violin would play and improvise together. They were later joined by Roger Chaput on guitar and Louis Vola on bass and Django’s brother Joseph on guitar as well. They became a group and recorded their first songs together under the label Ultraphone. It was under the Ultraphone label that Dinah, Lady Be Good, Tiger Rag and I Saw Stars were recorded in 1934. They soon named their group Le Quintette de Hot Club de France and recorded many more songs (Red hot jazz, 2008). When the war broke out in the late 1930’s, Grappelli decided to live in England during the war while Reinhardt returned to Paris. He continued to play with a small group and also put together various bands, and recorded additional songs in 1945 with Django Reinhardt and His American Swing Band. In 1946 Duke Ellington invited him to play with him in America. This was his first experience with an electric guitar. He toured only for two weeks with Ellington and returned to Paris somewhat disappointed with the American tour. He did learn some bop while in American as well electric guitar and continued to experiment with those back in Paris. Django continued his career performing in small cafes until 1951 when he retired to Samois-sur-Seine with Naguine and his son Babik. He spent his days fishing, painting and playing billiards. He also came out of retirement in 1953 briefly for his final recording; The Great Artistry of Django Reinhardt which was released in France as well as in America. He also toured in Switzerland in early 1953 and was set to tour in the Jazz at the Philharmonic tour of Europe, United States and Japan later in 1953. He began having difficulty with his fingers as well as experiencing severe headaches, but refused to see a physician. Django Reinhardt died of a stroke on May 16th, 1953 in Samois-sur-Seine at the age of 43 years old. After the funeral Naguine moved out of the caravan and burned all of Django’s belongings. This is traditional to the Manouche gypsies. The only thing that is kept is a picture. So, Django’s precious guitar was burned along with his other possessions. As well as the guitar that was gone, his music could not be played in keeping with the customs. After his death, it was only non-gypsy people who kept his music alive. Dregni, p262-268). An early death did not stop Django Reinhardt from becoming a star in the jazz world or in the gypsy world. I was amazed with what he was forced to overcome to play the guitar. The fire could have been enough to have many musicians stop playing, but his drive and passion to play forced him to overcome great odds. Also, despite being illiterate and unable to read music he was a huge success. I also found very interesting the Manouche customs, especially the customs surrounding death. Django Reinhardt is known as one the best jazz guitarists of all time.

The Compton Effect or Compton Scattering in Physics

The Compton Effect or Compton Scattering in Physics The Compton effect (also called Compton scattering) is the result of a high-energy photon  colliding with a target, which releases loosely bound electrons from the outer shell of the atom or molecule. The scattered radiation experiences a wavelength shift that cannot be explained in terms of classical wave theory, thus lending support to Einsteins  photon theory. Probably the most important implication of the effect is that it showed light could not be fully explained according to wave phenomena.  Compton scattering is one example of a type of inelastic scattering of light by a charged particle. Nuclear scattering also occurs, although the Compton effect typically refers  to the interaction with electrons. The effect was first demonstrated in 1923 by Arthur Holly Compton (for which he received a 1927 Nobel Prize  in Physics). Comptons graduate student, Y.H. Woo, later verified the effect. How Compton Scattering Works The scattering is demonstrated is pictured in the diagram. A high-energy photon (generally X-ray or gamma-ray) collides with a target, which has loosely-bound electrons in its outer shell. The incident photon has the following energy E and linear momentum p: E hc / lambdap E / c The photon gives part of its energy to one of the almost-free electrons, in the form of kinetic energy, as expected in a particle collision. We know that total energy and linear momentum must be conserved. Analyzing these energy and momentum relationships for the photon and electron, you end up with three equations: energyx-component momentumy-component momentum ... in four variables: phi, the scattering angle of the electrontheta, the scattering angle of the photonEe, the final energy of the electronE, the final energy of the photon If we care only about the energy and direction of the photon, then the electron variables can be treated as constants, meaning that its possible to solve the system of equations. By combining these equations and using some algebraic tricks to eliminate variables, Compton arrived at the following equations (which are obviously related, since energy and wavelength are related to photons): 1 / E - 1 / E 1/( me c 2) * (1 - cos theta)lambda - lambda h/(me c) * (1 - cos theta) The value h/(me c) is called the Compton wavelength of the electron and has a value of 0.002426 nm (or 2.426 x 10-12 m). This isnt, of course, an actual wavelength, but really a proportionality constant for the wavelength shift. Why Does This Support Photons? This analysis and derivation are based on a particle perspective and the results are easy to test. Looking at the equation, it becomes clear that the entire shift can be measured purely in terms of the angle at which the photon gets scattered. Everything else on the right side of the equation is a constant. Experiments show that this is the case, giving great support to the photon interpretation of light.
