The Troubling Nature of Pop Culture
The Troubling Nature of Pop Culture Weâve all been MTVâd. We grew up with pop drivel invading every dark corner of our media-saturated lives: The glowing box in the living room showcasing ideal families in ideal homes living ideal lives. The car stereo blaring bland top-40-isms during rush-hour traffic. Newspapers foretelling inescapable doom and irremediable despair without any hope of salvation or redemption. Magazines twaddling the latest gossip about such and such and whatâs his name. Our collective brains have soaked up the meaningless muck and are now waterlogged with platitudes and cultural niceties and the false expectations of the way life should be. American Express: Never leave home without it. Coca-Cola: Itâs the real thing. McDonaldâs: Iâm lovinâ it. We know these corporate slogansâ"and many othersâ"by heart. Weâve let them in without even knowing we were letting them in. Weâve accepted these mantras as maxims by which we should make our decisions. If someone continuously repeats a lie, does it eventually become the truth? Is it not safe to leave our homes without our credit cards? Is the realest thing in our lives a carbonated aluminum can of sugar? Do we really love the golden arches? Even Pringles admits they know we are programmed: Once you pop, you canât stop! Sadly, theyâre right. Itâs difficult to shake the sedative weight of everything weâve learned from pop culture. Fortunately, though, once you go pop, you can stop. We never opted-in to pop culture: it had us in its sinister clutch at birth, an invisible umbilical cord no one thought to cut. After all, whatâs the harm in a little TV, in a little late-night news, in catching up on the dayâs current events? Nothing. But when we simply accept the idiot boxâs catchy one-liners as epigrams by which we must make our most important decisions, we get lost quickly. Itâs easy to be passively entertained and informed, accepting catchphrases to be self-evident. Even the news has to be âinfo-tainmentâ these days so itâs more palatable to the casual listener (read: consumer). Thatâs because itâs easy to be entertained, but itâs hard work to seek out the truth, itâs difficult to form our own opinions based on multiple points of view, and itâs much easier to allow someone elseâ"be it Rush Limbaugh, Keith Olbermann, or a faceless corporation with a seemingly endless marketing budgetâ"to form an opinion for us. Besides the problems of its inherently passive nature, todayâs commercial-riddled pop-information canât inform us of lifeâs larger problems, of our deepest troubles and fears, of what it actually means to be aliveâ"what it means to be a human being in the most complex time in human history. The American Dream is brokenâ"it has been for decades, and attempting to go back to âthe way things wereâ will not fix it. âFixing itâ would only perpetuate the inevitable, making it worse in the long run. The longer we put off our troubles, the harder they are to deal with. Instead, as a culture, we must take responsibility. We must fix ourselves. We must create the disciplines necessary to be alive in this complex world. We must become aware of whatâs going on around us so ultimately we can be aware of whatâs going on inside usâ"only then will we know whatâs truly important.

Gerontology Interview - 1645 Words
Interview Paper My grandfather recently passed away 6 months ago. So I have personally witnessed my grandmother go through the grieving process as well as deal with her own sickness. Unfortunately my grandmother will have to enter a nursing home because my mother can no longer tend to her needs. This is a difficult time for my family because my grandmother doesnt want to go into a nursing home, but she requires 24/7 care. For my interview I chose the neighbors mother whoââ¬â¢s situation, age and lifestyle are very similar to my grandmotherââ¬â¢s. Her name is Lucy and she is 82 yrs. old living with her oldest daughter. I was pleasantly surprised with the outcome to the questions I asked her. We conducted the interview in her homeâ⬠¦show more contentâ⬠¦However, she did mention that she didnââ¬â¢t understand what young people saw in rap music. She said it is so negative and its causing young people to do bad things, but she assumed that it was just a phase that most will grow out of. Lucy remains busy by singing in her church choir. That seems to be the only outlet she has. Although choir rehearsal is twice a week, Lucy has been able to make it at least once a week. I know that there are people who do this with their church but I did not realize that some of them were much older adults. I think these activities help to prevent disengagement theory from being present in her life. She is so involved with church and itââ¬â¢ activities that she gets to continually interact with people and not lose that social connection to others. Lucy mentioned that she talks to someone from her church family at least 4 times a week and her church family fills that empty v oid left by the death of her husband. Her daughter lives with her and she plays the role of mother by doing the cooking and cleaning and not allowing Lucy to do anything for fear of hurting herself. This living condition does not make Lucy happy. . In the book ââ¬Å"Issues In Agingâ⬠by Mark Novak, the author speaks about people achieving a greater spirituality later in life.

Haitian-American Author of a Collection of Short Stories...
Edwidge Danticat, a Haitian-American writer, immigrated to the United States at the age of twelve from a Haiti that was filled with violent turmoil where she lived with relatives in a poverty-stricken area of Haiti. She soon learned English in the United States and began to develop as a young writer. Unlike most fictional writers, Danticat wrote her literature about the pain and suffering of her country from her own experiences. ââ¬Å"She often says that her voice is the only one of many representing the Haitian peopleâ⬠(eportfolio). Her collection of fictional short stories Krik? Krak! depicted the lives of Haitians at different points throughout the twentieth-century(Chen 36). ââ¬Å"A Wall of Fire Risingâ⬠is one of the short stories in the cycle inâ⬠¦show more contentâ⬠¦Little Guy recites this speech: ââ¬Å"A wall of fire is rising and in the ashes, I see the bones of my people.

At night I relive once more the last caresses from the hand of a loving father, a valiant love, a beloved friendâ⬠(a wall 319). The speech reveals the symbolic meaning of the title and its symbolic attachment to Haitian revolutionary history as a picture of rising fire is painted when Boukmanââ¬â¢s powerful words come out of Little Guyââ¬â¢s mouth. The theme of entrapment is starting to be revealed from the speech. The lives lost in the revolution, those that did not get to see freedom, resonate through the paper and becomes a reality.

I was given an opportunity to describe the very special moment of my life. The moment that changed it, that shook me and turned my world upside down. It was an early morning when my mom was seeing me off at the airport. We were sitting in the cafeteria holding hands and looking at each other without saying a single word. I could see tears in her eyes. She looked worried, upset and proud of me at the same time. Itââ¬â¢s not easy to let your still little daughter go on her first flight to unknown far-far away country and being aware of that you wonââ¬â¢t see her In the next couple of years. The emotions were overwhelming me. I was terrified and full of courage, worried and excited, already missed my family but couldnââ¬â¢t wait to take off. And here I was making a small step out of the plane In New York but a gigantic one Into my new future.

The Kinetic Energy Essay Example
The Kinetic Energy Paper The aim of this piece of work is to investigate the factors that affect how fast a marble/ball bearing travels once it has travelled down the curtain rail. Factors: There are 5 main factors that affect the speed of the marble/ball bearing once it hits the ground after travelling down a curtain rail.Ã The surface may well change as it changes from the curtain rail to the floor. It could be smoother or rougher. If its rougher the ball will slow down its speed quite quick due to friction whereas if it were smoother it would travel a further distance because it will have a higher speed. It will be easier to pass over the surface if it is smooth. The marble/ball bearing itself could be of importance. Its weight and diameter could affect the speed. The bigger and heavier the ball the shorter the distance it will travel because the speed will be slower than with a small light ball which will travel faster.Ã Another point would be the height of the beginning of the track from the floor. The higher the track the faster the ball will travel when it comes off the end. However, if the track is very close to the floor the marble/ball bearing will not get very far due to low speed. We will write a custom essay sample on The Kinetic Energy specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on The Kinetic Energy specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on The Kinetic Energy specifically for you FOR ONLY $16.38 $13.9/page Hire Writer This is the most important factor because it more or less determines the speed the marble/ball bearing is going to travel and how far it is going to travel.Ã Air resistance may play a minor part in the speed of the marble/ball bearing. There is nearly always air resistance therefore it could slow the ball down a tiny fraction.Ã The length of the track could play a large part. The longer the track the faster the marble/ball bearing has to go to get a longer distance. If it is a short track the ball bearing will be at a higher speed as it reaches the floor because it hasnt had much time to slow down. Fair Test For this to be a fair test everything has to be done equally. If you decide to choose the height of the track to be the most influential factor then that is the only thing we must vary. The same ball must be used for each test. If not the size of the ball could speed up or slow down the average speed of the same ball. The same track must be used each time. If not the different tracks could have a rougher or smoother surface from each other and this may affect the speed of the marble/ball bearing once reached the floor. Before timing each test the distance measured and timed at the end of the curtain rail must be the same each time you do it. It must also be done in the same place to make sure that the air resistance is the same. All these aspects must be undergone for it to be a successful experiment. Predication and Scientific Knowledge My prediction is that the higher the curtain rail at the beginning the faster the marble/ball bearing will travel along the floor and the further it will travel along the floor. The lower the curtain at the beginning the slower the ball will travel because there isnt as much gravity forcing it along the rail. On a rollercoaster for example there is Gravitational Potential Energy at the top of a drop which converts into Kinetic Energy when it reaches the bottom of the drop and slows down. Gravitational = mass x height x gravitational Field Strength Potential Energy Kinetic Energy = 1/2 x mass x speed 2 There is also transferred into heat energy and sound energy. But then if we forget about the laws of friction and the energy given off from friction both Gravitational Potential Energy and Kinetic can be equal. If the height changes on one the velocity will changes to be equal as well. Method: To find the speed of the marble/ball bearing travelling along the floor it will have to be timed over a certain distance. The distance should be accurate and reasonable to be able to get a good time in. It should be 2 or 3 metres. Preferably 3. It should be measured from five heights and timed on each one. This should be done at least 3 times to get a good average and set of results that you can work with. The range of heights need to be equally set apart. In this case it should be 10cm, 20cm, 30cm, 40cm, and 50cm. The times need to be recorded from when the ball leaves the curtain rail to where the 3 metres is finished. All results must be recorded. Preliminary Experiment: In our preliminary experiment we found that Gravitational Potential Energy converts into Kinetic Energy once at the bottom. The marble/ball bearing gradually slowed down as it travelled along the floor. Another thing on the preliminary experiments was that once the ball had fell down the bottom and up the other side of the curtain rail and reversed in couldnt reach the same height as the start because the marble/ball bearing has lost most of its Gravitational Potential Energy and therefore cant turn it into Kinetic Energy anymore. The Obtaining.
