Part I—Too Much of a Good Thing Times were difficult in Habersham County. The skyrocketing prices of fuel and food were threatening to bankrupt the Johnson family’s small farm, which was no match for the multi-million-dollar mega-farms that had been popping up all over the southeast. Joseph, the family patriarch, was especially troubled by the farm’s financial circumstances. He knew that this year’s corn crop was his best chance to save the farm, and his distress was evident to his family as they sat around the dinner table. â€Å"Michael, I’m going to need your help tomorrow,† Joseph said to his eldest son. â€Å"I have to go into town to pick up a part for the combine so I can fix it before it’s time to harvest in a few months. I need you to spread the potash and phosphate on the corn because we’re expecting some rain by the end of the week. † Michael, his mouth full of fried chicken, nodded in agreement. He wasn’t all that interested in farming, which over the years had been a point of contention between him and his father. At the moment Michael was thinking more about the time he’d be missing with his friends, but he also realized how vital this chore was to his father and the farm. â€Å"I’ll do it right after school, Dad,† he replied. The following afternoon, Michael was loading heavy bags of fertilizer into the drop spreader on the farm tractor. His father’s cheerless demeanor the previous evening weighed heavily on him. Michael knew that 25 bags of the potassium and phosphorous-based fertilizer was the normal load to cover the 40 acres of corn the family had planted that spring. But as he was emptying the 25th bag into the spreader, an idea flashed through his mind: â€Å"If we need a good corn crop to make it, maybe I should add a little extra fertilizer. † Michael decided that some extra fertilizer couldn’t hurt, so he quickly loaded 15 extra bags. He was certain that adding the extra fertilizer would produce a massive crop when it came time to harvest in a few months. Michael hadn’t told his father about the extra fertilizer he’d added to the corn, wanting to see his father’s surprise over the size of the harvest in a few months. As expected, the rain started Friday afternoon; Michael was certain it would start an incredible growth spurt in the newly fertilized, young corn plants and that his family would hit pay dirt in a few months. He was out of bed early on Saturday morning, taking his four-wheeler down to the cornfields. He expected to see a vibrant green sea of young corn, extra healthy due to the fertilizer â€Å"boost† he had given them. His stomach dropped a bit as he stared out at a field of sickly looking corn plants, their leaves pale green and slightly wilting. â€Å"Maybe it rained too hard and that beat the plants up a little,† thought Michael, trying to be optimistic. â€Å"I’ll check on them again in a few days. I’m sure they’ll have perked up by then! † The next few days didn’t bring the results Michael was hoping for. The corn plants looked even worse! The leaves were beginning to yellow significantly and were continuing to wilt. Having watched his father grow corn for most of his 14 years, Michael knew this crop wasn’t going to make it. A lump was forming in his throat as he made his way back to the house, not sure how to tell his father about the corn. Questions 1. What sort of environment (hypotonic, hypertonic, isotonic) did the extra fertilizer create around the roots of the corn? 2. Keeping in mind your answer to the previous question, what do you believe caused the corn plants to wilt and eventually die? 3. If Michael’s mistake had been caught earlier, is there anything that could have been done to prevent the corn from dying? 4. Generally, people water their plants with 100% H2O—no solutes added. What sort of environment does this create around the roots of the plant? Part II—Too Little, Too Late Meanwhile, elsewhere in Habersham County, Tom was feeling slightly nervous as he exited the staff lounge and entered the hustle and bustle of County Hospital’s ER to begin his first shift as an RN. The first few hours of his shift passed slowly as Tom mostly checked vital signs and listened to patients complain about various aches, pains, coughs, and sniffles. He realized that the attending physician, Dr. Greene, who was rather â€Å"old  school† in general about how he interacted with nursing staff, wanted to start him out slowly. Tom knew, though, that the paramedics could bring in a trauma patient at any time. After his lunch break, Tom didn’t have long to wait before the paramedics burst in through the swinging double-doors of the ambulance bay wheeling in a young man on a gurney. Edward, a veteran EMT, recited the vital signs to Tom and Dr. Greene as they helped push the gurney into the trauma room, â€Å"18-year-old male, GSW to the right abdomen, heart rate 92, respiratory rate 22, blood pressure 95/65, no loss of consciousness. † A gunshot wound! Tom knew that gunshot wounds were sometimes the most difficult traumas to handle. Once inside the trauma room, Dr. Greene began his initial assessment of the patient while Tom got busy organizing the things he knew would be needed. He attached a pulse-ox monitor to the patient’s index finger so Dr. Greene could keep an eye on the O2 levels in the patient’s blood and he inserted a Foley catheter so the patient’s urine output could be monitored. After finishing his initial duties, Tom heard Dr. Greene saying, â€Å"It looks like the bullet missed the liver and kidney, but it may have severed an artery. That’s probably why his BP is a bit low. Tom, grab a liter of saline and start a fast IV drip †¦ we need to increase his blood volume. † Tom grabbed one of the fluid-filled bags from the nearby shelf, attached a 12-gauge IV needle to the plastic tubing, and gently slipped the needle into the patient’s antecubital vein. He then hung the plastic bag on the IV stand and let the fluid quickly start to flow down the tubing and into the patient’s vein. The reaction was quick and violent. The patient’s heart rate began to skyrocket and Tom heard Dr. Greene shouting, â€Å"His O2 saturation is falling! Pulse is quickening! What is going on with this guy?! † Tom stood frozen in place by the fear. He heard Dr. Greene continuing, â€Å"Flatline! We’ve lost a pulse †¦ Tom, get the crash cart, we need to shock this guy to get his heart going again! † Tom broke free from his initial shock and did as Dr. Greene had ordered. He then started CPR as Dr. Greene readied the cardiac defibrillator to shock the patient. They continued to alternate between CPR and defibrillation for almost an hour, but to no avail. As Dr. Greene announced the time of death, Tom felt a sickening feeling in the pit of his stomach. He couldn’t believe that he had lost his first trauma patient! Then Tom noticed that the fluid in the Foley catheter bag was bright red. â€Å"Dr. Greene, there’s hemoglobin in the Foley bag,† he said. â€Å"How could that be? † responded Dr. Greene. Tom began to trace back over his steps in the trauma, trying to think of anything that could have caused the hemoglobinuria. His mounting fear turned to outright terror as he looked at the now empty bag on the IV stand. Its label didn’t read â€Å"Saline,† but rather â€Å"Distilled Water. † He looked at Dr. Greene, his heart quickly sinking, and said, â€Å"I think I may have killed the patient. † Questions 1. What problem did the distilled water in the patient’s bloodstream create? 2. What happed to the patient’s blood cells as a result? 3. Considering the function of red blood cells, why did the patient’s oxygen levels fall? 4. After Tom made his error, is there anything that could have been done to save the patient’s life?

Native American Cultural Assessment: The Cherokee Essay -- essays rese

The word Cherokee comes from a Creek word "Chelokee" meaning "people of a different speech." In their own language the Cherokee called themselves the Aniyunwiya or "principal people" or the Keetoowah, "people of Kituhwa." The Cherokee are perhaps one of the most interesting of Native American Groups. Their life and culture are closely intertwined with early American settlers and the history of our own nation’s struggle for freedom. In the interest of promoting tolerance and peace, and with regard to the United States government’s handling of Native affairs, their story is one that is painful, stoic, and must not be forgotten. The Cherokee people were a large and powerful tribe. The Cherokees' Macro-Siouan- Iroquoian language and their migration legends demonstrate that the tribe originated to the north of their traditional Southeastern homelands. Linguists believe that the Cherokee migrated from the Great Lakes area to the Southeast over three thousand years ago. The Cherokee language is a branch of the Iroquoian language family, related to Cayuga, Seneca, Onondega, Wyandot-Huron, Tuscarora, Oneida and Mohawk. Original locations of the Cherokee were the southern Appalachian Mountains, including western North and South Carolina, northern Georgia and Alabama, southwest Virginia, and the Cumberland Basin of Tennessee, Kentucky, and northern Alabama. The Cherokee sometimes refer to themselves as Ani-Kituhwagi, "the people of Kituhwa". Kituhwa was the name of an ancient city, located near present Bryson City, NC, which was the center of the Cherokee Nation. Long before Columbus discovered the "New World" or Spanish explorer Hernando de Soto arrived, the Cherokee territory stretched from the Ohio River to the north, and southward into Georgia and Alabama. Their homelands extended over 135,000 square miles. Cherokee villages had populations of about 350 to 600 persons. Before contact with Europeans, families built round, earth-covered homes for the winter. For the warmer summers they built larger, rectangular homes. The rectangular homes had upright poles forming a framework. The outer covering was bark, wood or woven siding coated with earth and clay. The Cherokee were primarily an agricultural people. They relied heavily on corn, beans, and squash, supplemented by hunting and the gathering of wil... ...r near the North Carolina reservation. Cherokee tribal governments have fairly liberal membership standards compared to other tribes. Some population estimates exceed 370,000, which would make the Cherokee the largest Native American group in the United States It is amazing that through European epidemics, attempts to assimilate eradicate and remove, that any Cherokee are left today. Despite all they have endured and lost, Cherokee levels of education and living standard ranks among the highest of all Native American tribes. I am proud to be an American citizen. I am also especially proud that my Mother’s Great-Grandmother, a descendant of Trail of Tears survivors, was Cherokee. BIBLIOGRAPHY Thomas E.

True Life: Reality Television Is Scripted

Since the 1990’s, when reality television first started becoming widely popular, we have been able to see into the lives of different kinds of people, often turning everyday people into celebrities. With some of the most popular reality television shows, like Big Brother, True Life, American Idol, and most recently Jersey Shore, we are led on to believe that it is all real (â€Å"The Hunger Games Theme of Versions of Reality†). The reality of this television though is that most of it is either altered or manipulated just for our own entertainment.The directors of some of these shows often script, manipulate and plan situations to make the shows more appealing to their audiences (â€Å"How Much of the Reality†). Even in popular books like The Hunger Games where reality television is a theme, it is shown that it is changed just for the entertainment of the viewers (â€Å"The Hunger Games Theme of Versions of Reality†). While it is perceived to be real, the t itle of â€Å"reality television† is a misnomer because most showed turn out to be fake and scripted.Reality television directors push their participants into exploiting themselves for the entertainment of their viewers. There are hundreds of reality television shows currently on, and they make up a large portion of what people are exposed to in popular media, especially young people. While most shows won’t admit to being scripted, in fear of losing their â€Å"reality television† title, some shows have admitted to planning situations to get a good reaction out to the cast, which makes for more interesting television.Also, some directors have said that they do push the participants to the edge when they can to get interesting reactions out of them. They say there are lines that they don’t tend to cross, but they like to mess with the mind of their participants of their shows (â€Å"How Much of the Reality†). By pushing the people to their limits, a nd manipulating situations, they basically do whatever they can to produce an entertaining show.In the country of Panem, where the book The Hunger Games takes place, reality television is something that the people look forward to each year. The people of Panem and especially the people in the Capitol gather together and look forward to seeing the games each year; just as a group of friends may get together and watch the season premiere of Jersey Shore. The people look forward to one show in particular though, called The Hunger Games.But this reality show they watch is a little different than the ones we watch; instead of living in a house with strangers, or hopefully finding true love, the contestants kill one another until one is left standing (â€Å"The Hunger Games Theme of Versions of Reality). The game makers, who are the ones controlling the game don’t seem to always make it fair, that’s where is seems scripted in a way. There are several examples in the book wh ere The Hunger Games was altered simply for the entertainment of the viewers.First, throughout the training Katniss, the main character of the story, is told to be and act like someone whom she is not. Katniss is told to act friendly, and personable, and desirable so that she will have a stronger chance to surviving the games and it will make the viewers like her (Collins 135). Also another important example of when the Capitol changed the game for entertainment purposes is when they set fire to the forest to keep Katniss in the game (Collins 171). They also set the fire to give the viewers some excitement.In today’s reality TV, the directors will stir up conflicts and situations often to create excitement. In modern day reality television and also a fictional version of reality TV in The Hunger Games, entertainment of their audiences is more important than the actual realness of what they are showing. Being said to be some of the most romantic shows on television, an average of 17 million people tune in each week to view The Bachelor and The Bachelorette. What seems to be true love on screen, doesn’t always translate to that off screen.The success rates of the show’s relationships are low. In the 23 combined seasons of The Bachelor and The Bachelorette only 17% of couples are still together. Most of the couple who are not together anymore broke up between 1 month and 1 year after the finale of the show. With so many failed relationships resulting so quickly from the show, it makes viewers wonder how much of the romances were actually enhanced for the for entertainment of the show (â€Å"How Many Bachelor†).Reality television is widely popular in today’s entertainment; it seems like you can’t turn the TV on without having not having the option of catching up on a different version of reality television. We are led on to believe that it is all real, but the reality of these television programs is that it isn’t al l real. A lot of it is faked just to get a good show, and to entertain people. While simply the genre of reality TV naturally drives people’s interests in, so the directors manipulate situations and people reactions to produce something that they hope to get as many viewers as possible.Its supposedly â€Å"reality television,† so why isn’t it all real?

Jealousy and Race in Othello - 1430 Words

Othello is one of Shakespeare’s tragedies; originally written as a play and performed to an Elizabethan audience. Othello and many of Shakespeare’s other plays have been performed to various audiences since, and have been adapted into Opera, Ballet, Film and television productions. Othello has survived the centuries to this day and age; and continues to captivate and remain relevant to a modern audience; Othello certainly is a timeless classic work of art. â€Å"The object of tragic imitation is men in action.† As stated by Aristotle in his work, Poetics. Othello consists of men in action, in more than one sense; Othello (titular character protagonist), Iago and Cassio are ‘men of action’ and additionally, throughout the play we are able to†¦show more content†¦Iago wakens Brabantio (Desdemona’s father), â€Å"Even now. Now†¦ an old black ram†¦white ewe†¦Ã¢â‚¬  Iago wakens Brabantio (Desdemona’s father) of n ews that his daughter has eloped with Othello. He uses racial slurs (white ewe, old black ram), Iago’s imagery of animals also makes reference to Othello’s supposed untameable sexual urges and bestiality which were common beliefs about ‘moors’ or ‘blacks’ during the Elizabethan era. Brabantio’s mind is shaken as Iago manipulates his (Brabantio’s) fears of inter-racial marriage/sex. Iago also refers to Othello as the devil (which is ironic due to Iago being more likely to be likened as such, with his ‘motiveless malignity’ and Machiavellian schemes.) which plays on the Elizabethan notion that black men were evil and the devil often took the shape and form-factor of a black man. Brabantio later accuses Othello of using Black Magic to win Desdemona’s hand, which may be in reference to said notion. The Duke of Venice, in defence of Othello says,â€Å" And, noble signor, ... far more fair than black† , Not a ll Venetians see Othello in the same light as Brabantio, The Duke and the senators are obviously filled with veneration for the great military leader. Shakespeare plays with light and dark imagery here, although the Duke speaks of Othello in a highly virtuous and courteous manner, he still treats the notion of ‘blackness’ as an undesirable feature, or bearing negative connotations.
