Video Games And Its Effects On The Classroom - 929 Words

As technology changes each generation, so does choice of pastime. The most notable one being a kid’s obsession with video games, spending hours glued to the monitor. Instead of fighting it, educators around the nation are accepting and adopting the video game interest to their classrooms. Many may argue that videogames are a distraction and are too violent, however, if implemented in school systems the games used will be safe and focused around the core subject. Otherwise, â€Å"there are teachers out there that are interested in leveraging game for learning, they re not alone.† as the director of the academic and digital learning Lucas Gillispie says, It makes it logical to implement video games to the class lesson as it provides a fun and effective way for students to learn with. One of the most popular game amongst young children, Minecraft, have already been implemented in many school systems nationwide. Minecraft is a digital lego like, sandbox game, meaning that t he player has complete freedom within that game world. Players manipulate the world around them through, as the game name says, mining and crafting. The game itself has an overwhelming amount of items mirror the real world with, giving Minecraft a high educational value to the point that it has it’s own educational variety, MinecraftEdu. According to the T H E Journal’s â€Å"4 Innovative Ways To Teach With Video Games†, their use of Minecraft was intentionally used as an after school program for at-risk students.Show MoreRelatedThe Impact of Technology1443 Words   |  6 PagesTechnology, mainly computers and video games, have made a vast difference in our society.

A Causative Agent of Food-borne Poisoning Free Essays

Bacillus cereus is an aerobic and facultative anaerobic, gram-positive bacteria causing toxin-mediated food poisoning. Optimum temperature for its growth is 30-37Â °C. However, it can also tolerate a wide range of temperature; some strains can grow up to 55Â °C while others can grow at temperatures as low as 4 to 5Â °C (Microbial Pathogen Datasheets, 2001). We will write a custom essay sample on A Causative Agent of Food-borne Poisoning or any similar topic only for you Order Now Many strains from dairy products are able to thrive at lower temperatures. The minimum pH requirement for growth is 4. 3, while maximum pH is around 9. 3. This bacterial population grows best in the presence of oxygen (Microbial Pathogen Datasheets, 2001). Nevertheless, since this species is facultative anaerobic it also grows well in anaerobic conditions (Louisiana Office of Public Health, 2004). Toxin production has been found to be much lower under anaerobic conditions. Bacillus cereus is a spore-forming micro-organism which occurs naturally in most foods. It causes two different and distinct forms of food poisoning: an emetic illness and a diarrhoeal illness (Louisiana Office of Public Health, 2004). Bacillus cereus causes food-borne emetic illness by producing a highly stable toxin that survives high temperatures and exposure to trypsin, pepsin and pH extremes. Bacillus cereus levels in foods associated with emetic form of food poisoning have ranged from 1,000 to 50 billion colony-forming units (cfu)/gram (Louisiana Office of Public Health, 2004). High numbers of bacterial population have been also detected in faecal samples from affected persons. Diarrhoeal illness is mediated by a heat- and acid-labile enterotoxin produced during growth of vegetative cells in the small intestine (Granum, 1994). Four different enterotoxins have been characterized. Two are protein complexes such as non-haemolytic enterotoxin (NHE) and haemolysin BL (HBL) and two are enterotoxic proteins such as enterotoxin T (bc-D-ENT) and cytotoxin K (Lund, DeBuyser Granum, 2000). The occurrence of the diarrhoeal-type syndrome has been largely reported in the US and Europe, where the disease has been greatly associated with foods such as meat, vegetable, poultry, desserts and sauces (Giannella and Brasile, 1979). Prevalence of the vomiting type syndrome has been reported in the United Kingdom, Canada and USA, food borne poisoning is commonly associated with the consumption of cooked fried rice (Mortimer and McCann, 1974). Serotyping studies conducted by Taylor and Gilbert (1975) showed that strains from incidents of food poisoning in US and Europe characterised by a longer incubation period and with diarrhoea as the main symptom have provided serotypes 2, 6, 8, 9 and 10, whereas those which caused the rice-associated emetic illness in United Kingdom, Canada and USA were serotypes 1, 3 or 5. Bacillus cereus food poisoning is mostly associated with rice dishes, and sporadically with other food stuffs such as meat, vegetable, pasta, dairy products, sauces, soups and sweet pastries. Bacillus cereus food-borne poisoning is also associated with pudding, cream, spices, dry milk, dry potatoes and spaghetti sauces. Bacterial contamination of the food product by the large occurs prior to cooking. Even after cooking the microbial population thrives because vegetative forms can grow over a wide range of temperatures from 25Â °C to 42Â °C and are also capable of producing endotoxins. Endospores have the ability to survive extremely high and low temperatures. When they are allowed to cool fairly gradually, they once again begin to germinate and multiply. Spores are highly resistant to dry heat than moist heat. Emetic toxins are also extremely resistant to heat. They can survive 90 min at 126Â °C, while diarrhoeal toxins are inactivated at 56Â °C in 5 min. Clinical Description Bacillus cereus is widely known as the etiological agent of food-borne poisoning, causing both gastrointestinal and non-gastrointestinal diseases. Both diarrhoea and emesis can be clearly distinguished by their clinical features. Diarrhoea is provoked by heat-labile enterotoxins, while emesis is caused by a heat-stable depsipeptide toxin called cereulide (Ehling, Fricker Scherer, 2004). The clinical syndromes associated with the diarrhoeal form of illness are longer incubation about 6 to 24 hours period, very watery diarrhoea (similar to that of C. perfringens), presence of moderate to severe abdominal cramps, nausea and vomiting in some patients, duration of illness ranges from a minimum of 20 hours to a maximum of 36 hours. Clinical features associated with the emetic form of illness are shorter incubation period of about 1 to 6 hours, presence of vomiting and abdominal cramps; diarrhoea is not severe and is present in only about a third of affected individuals (similar to poisoning by S. aureus), duration of sickness ranges from 8 to 10 hours. In both types of syndromes, fever is exceptional and disease is usually docile. Bacillus cereus also can cause other diseases such as local skin and wound infections, ocular infections, fulminant liver failure. Invasive disease, including bacteraemia, endocarditis, osteomyelitis, pneumonia, brain abscess, and meningitis are also caused by Bacillus cereus. Ocular involvement includes panophthalmitis, endophthalmitis, and keratitis (Louisiana Office of Public Health, 2004). Apart, it can bring about other infections namely, pneumonia, meningitis, encephalitis, in addition to brain and liver abscesses (Drobniewski, 1993). It is a rare cause of endocarditis (Fowler et al. 2005) reported in patients with prosthetic heart valves, rheumatic heart disease, intravenous drug use (IVDU), and in patient with leukaemia. Food Poisoning by other Bacillus species Toxic food poisoning is not only caused by Bacillus cereus, several other Bacillus species have also been implicated in food poisoning incidents. The most important species are B. subtilis and B. licheniformis. These organisms are capable of producing an extremely heat-stable toxin which seems very similar to the emetic type produced by B. cereus (Kramer and Gilbert, 1989). These species are widely associated with food products like meat, vegetable, flour, pastry, sausage rolls, meat pies and pastries, curries and various ethnic dishes with rice, and stuffed poultry. Bacillus subtilis is associated mainly with meat, vegetables in pastry, poultry products, and occasionally with bakery items such as bread, crumpets, sandwiches, and ethnic meat or seafood dishes. Food poisoning syndrome associated with B. subtilis causes acute onset nausea, vomiting and stomach cramps, incubation range is 2-5 hours, often with diarrhoea. Poisoning due to B. licheniformis shows the following symptoms; diarrhoea is more common than vomiting, incubation period is about 8 hours. Another species which was isolated in high numbers from rice associated with a food poisoning outbreak was B. pumilus. Symptoms were consistent with those similar for food poisoning by other Bacillus species than B. cereus. C. perfringens food poisoning produces a heat-labile toxin which caused predominantly lower gastrointestinal (diarrheal) disease about 12 hours after ingestion much similar to the diarrheal type syndrome caused by B. cereus. Case Studies In August 2003, five children of a Belgian family became sick after eating pasta salad. The pasta salad prepared on a Friday was taken to picnic on Saturday. The leftovers had been stored in the refrigerator. The following Monday evening the pasta was served for supper to the children. Since the pasta had an unusual odour three children (aged 14, 10 and 9) did not eat much, they ate very little quantities. After 6 hours the youngest child (aged 7) started vomiting and complained of respiratory distress. She was immediately rushed to the hospital. Upon arrival at the hospital the other 3 children also felt nauseous and started vomiting. The condition of all the children began to worsen; hence they were transported to the University Hospital in Leuven. However, during transfer, the child (aged 7) had severe pulmonary haemorrhage, quickly followed by coma, diffuse bleeding, and severe muscle cramps. She died within 20 minutes, at 13 hours after the intake of pasta. Autopsy report revealed the presence of Bacillus cereus in her gut content. The other 3 children were kept under treatment for 8 days and they gradually recovered (Dierick et al. 2005). This case elucidated the probable severity of the emetic illness, also stressing on the importance of sufficient refrigeration of cooked food. Some B. cereus strains are known to be sychrotrophic and these strains have the maximum emetic toxin production between 12 and 15Â °C. In the present case, the temperature of the refrigerator where the pasta salad was stored was 14Â °C. This probably allowed B. cereus strains to multiply quickly to attain a count of more than 108 CFU/g in 3 days along with a very high toxin production (Dierick et al. 2005). Food borne poisoning was reported in a military camp in Jurong, Singapore. This food poisoning outbreak involved 19 army personnel who became unwell after breakfast. All these army personnel had been served fried rice by a food stall in a civilian canteen. The illness was characterized by vomiting (89. 5%), abdominal cramps (52. 6%), diarrhoea (47. 4%), headache (47. 4%) and fever (10. 5%) (Tay, Goh Tan, 1982). The incubation time extended from 13/4 hours to 51/2 hours. Bacillus cereus was detected in the vomitus of the affected soldiers (Tay, Goh Tan, 1982). This makes it clear that Bacillus cereus is a causative agent for the food borne poisoning resulting in emetic and diarrhoeal illness. This species contaminates food products, especially cooked rice and refrigerated products. It is therefore essential to follow proper cooking and refrigeration methods. Proper cooking and storage of foods, especially rice cooked for later use, will facilitate to thwart food borne epidemics. For the most part B. cereus food borne outbreak is an outcome of eating cooked foods which are cooled slowly and stored the wrong way. Generally food should be stored at temperatures higher than 60Â °C or quickly chilled to less than 10Â °C immediately after cooking. Bibliography Dierick, K. , Coillie, E.

Using Animals for Research

Table of Contents Introduction Why Use Animals Research Consideration Successes of Animal Research Ethical Issues in Using Animals for Research Conclusion Works Cited Introduction Researches have played a major role in improving the health standards of human beings and animals in general. In the past, pandemics and epidemics used to rein terror on human beings and animals. Diseases like Rinderpest, chickenpox, and plaque used to claim the lives of many individuals, however successful researches provided cures for these diseases and they no longer pose any threat. In order to find successful cures for human beings, it has proved necessary to use animals in research.Advertising We will write a custom research paper sample on Using Animals for Research specifically for you for only $16.05 $11/page Learn More Research using animals has in turn proved to be very reliable and efficient; many of the cures that have been developed have in one way or the othe r involved animal research. Using animals in research should therefore not be opposed rather should be unanimously endorsed. Why Use Animals Using animals in research, not only benefit human beings but also animals. It has been a known fact that human beings and animals are closely related and they get many of the same illnesses. Some animals are known to stand in for humans with particular diseases. In general, animal research is the type of research, survey, experiment that involves vertebrates such as mice, pigs and primates. On the other hand, clinical research is the study that entails scientists to use humans. These studies are critical and for research to reach this stage there must have been prior extensive preliminary tests in animal research studies. It is thus logical that animals be used to improve their lives and that of human beings. The world keep on fluctuating with many new diseases reported at every historical epoch (Sharp 1). It is thus obvious that emergence of n ew diseases, resistance of existing one and the need of developing vaccines makes research inevitable. These diseases and various ailments affect the immune system of animals and humans, making it weak and unable to withstand or combat the antigens. These activities take place in the body of a being and there is no way one can understand the nature of the antigens without dissecting the respective affected beings. Since the being’s immune system has failed to prevent the body from the attacks, there is no way a sick or dead organism can become ideal for conducting successful research on devising the cure of the disease that has already defeated its immune system. The affected being is crucial in understanding the nature of the disease but another healthy being is even more important in devising a cure (Herren 67). Based on the need to create a disease free world, it is inevitable to avoid research. Given the fact that researches in medical and scientific fields are inevitable , animals become the ideal and most appropriate specimen to use since human beings cannot be used in the preliminary researches.Advertising Looking for research paper on biology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Human beings have also become increasingly used in researches. For a medicine or a vaccine to be verified and proved successful, then at one time, or the other, human beings must be used in the research work. If human beings can be used in the research work then there is no way that animals can be exempted (Kalat 23). Research Consideration Contrary to what has been the main argument in opposing use of animals in research work, all medical and scientific researches are carefully planned including research with animals. Animals are not, unjustifiably exploited nor put through painful experiments without an important agenda. The researchers weigh several sensitive considerations before approving each study. In medical res earch using animals as specimen, the most important aspect to take into account is the relevance of the research to human or animal health. Researchers contrary to what has been the general notion protect animals’ welfare. Researchers only use the most appropriate species and in the fewest numbers possible (Greenhaven Staff 12). Almost all researchers in ensuring that all animals are treated in the most humane way enduring the least distress follow the federal law in the US. Animals should be used and have always been used in researches because of the various formidable reasons. Animals are used because they are in many ways like human beings especially in the normal and basic body functioning like breathing, eating, hearing and seeing. Nature has been regarded as economical and the same processes are known to be recycled over time. By using animals, scientists are assured of finding crucial and linking comparisons with human beings. Some diseases like the one caused by tsets e fly affect both animals and human beings (Chiras 34). Animals are thus the perfect specimen to use when in the process of conducting a research; it is impractical or unethical to use humans. Animals are also known to be susceptible to the same health problems like the one affecting human beings. They are therefore convenient, taking into account that they also have short life cycles. Moreover, the various medical research centers are able to control and diversify the environment around the animal for example diet, temperature and lighting, something that s almost impractical to try on people. Human beings cannot be exposed to health risks for researchers to observe the course of a disease.Advertising We will write a custom research paper sample on Using Animals for Research specifically for you for only $16.05 $11/page Learn More Successes of Animal Research Researches using animals have been very successful and there is no founded reason to stop or o ppose these endeavors. Some of the most successful studies using animals have been highlighted below. Heart disease and its related conditions affect almost a quarter of the US population costing more than three hundred billion dollars in budget allocation and is the number one killer. Using animals such as dogs and cats, the basic heart mechanism have been studied and in fact, the study with dogs immensely contributed to the basic methods of controlling heart disease being devised. The modern heart treatment methods were also devised after successful study with dogs. Heart transplants, cardiac bypass, angioplasty and other treatments all resulted from this study with dogs; in addition, the various methods of diagnosis and treatment were also developed. These are electrocardiography, coronary blood flow measurements among others. HIV/AIDS has become one of the most feared pandemic to, ever hit, the earth. All countries of the world are affected in one way or the other, the hardest h it being in the sub-Saharan Africa. To this date, there is no cure that has been found for the pandemic. However various advancements have been made, the comprehensive understanding of the viruses that causes the pandemic has been derived from the study of similar viruses in monkeys, chicken and cats. Vaccines are in the process of being tested on mice and monkeys before being administered on volunteers (Research Development 2). In the past, bacteria infections were deadly and fatal; they were the main causes of death ad other acute diseases. Although in the contemporary modern world bacterial infections are extremely common and have affected people on numerous occasions during their lifetime, they are now readily treatable with antibiotics. With animals in research, in this case mice and other rodents, penicillin and other antibiotics were established as effective treatments for bacterial infections. Animals thus continue to provide crucial information to scientists on ways of comb ating certain deadly diseases (The American Physiological Society 10).Advertising Looking for research paper on biology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Ethical Issues in Using Animals for Research The concern over the ethical issues arising in the use of animals has always been voiced. Those that oppose the use of animals being used in researches feel that animals are living beings and if people would not wish to be subjected to pain, then, it is ethically wrong to do the same to helpless animals. Those people who keep animals as pets feel much offended by the use of animals in research as they describe their relationship with the animals as equivalent to that with human beings. They talk of compassion, love, loyalty and so forth. It has also been argued that students may sometimes fail to euthanize animals for research and thus subjecting them to undesirable pain. There are no measures in place to ensure such kinds of students are deterred (Herren 325). Conclusion Using animals in research is desirable. Scientists do not conclusively understand human biology to an extent of directly applying new medical treatments on people or the daily evolving surgical procedures and processes. The desire to look for lifesaving cures cannot be overlooked as this is the desire of humanity to have a society where human suffering ad agony is minimal. Using animals especially in biomedical researches is thus inevitable and objective. Works Cited Chiras, Daniel. Human Biology. Sudbury: Jones and Bartlett Learning, 2010. Print. Greenhaven staff.

Expedient vs. Expeditious

Expedient vs. Expeditious â€Å"Expedient† vs. â€Å"Expeditious† â€Å"Expedient† vs. â€Å"Expeditious† By Mark Nichol What’s the difference between expedient and expeditious? The words were originally synonymous, but their meanings diverged long ago, and the distinction is small but significant. Both words derive from the Latin term expedire, which means â€Å"disengage† or â€Å"prepare.† (The literal meaning is â€Å"free the feet.†) As you may have guessed, that’s also the source of expedition, in the original sense of â€Å"journey† and the associated meaning of â€Å"those on a journey.† (The adjective form is expeditionary.) From expedire came the word expedite, meaning â€Å"dispatch or issue,† â€Å"do promptly,† or â€Å"speed up.† (Expediate is an unnecessary variant.) Two adjectives developed from this term: Expeditious originally meant â€Å"fitting† or â€Å"useful,† but it later acquired the sense of â€Å"promptly efficient† and lost its original meaning, which expedient retains. Expedient has two connotations, once neutral and the other more common slightly pejorative: Something that is expedient may be suitable, but the word more likely reflects what is done out of self-interest or because it is most convenient rather than the best solution. The adverbial form of expedient is expediently; the noun forms are expedience and, better, expediency. The adverbial form of expeditious is expeditiously, and the noun form is expeditiousness. The unrelated word expeditation (the verb form is expeditate) is closer to the literal meaning of the Latin source; it means to declaw a dog or remove the pads of its feet to deter it from chasing animals the word is therefore almost an antonym of expedite and I hope it’s obsolete.

His father my grandfather was a cook, a domestic servant to the British. But my grandfather had larger dreams for his son. Through hard work and perseverance my father got a scholarship to study in a magical place, America, that shone as a beacon of freedom and opportunity to so many who had come before. While studying here, my father met my mother. She was born in a town on the other side of the world, in Kansas. Her father worked on oil rigs and farms through most of the Depression. The day after Pearl Harbor my grandfather signed up for duty; joined Patton’s army, marched across Europe. Back home, my grandmother raised a baby and went to work on a bomber assembly line. After the war, they studied on the G.I. Bill, bought a house through F.H.A., and later moved west all the way to Hawaii in search of opportunity. And they, too, had big dreams for their daughter. A common dream, born of two continents. My parents shared not only an improbable love, they shared an abiding faith in the possibilities of this nation. They would give me an African name, Barack, or †blessed,† believing that in a tolerant America your name is no barrier to success. They imagined They imagined me going to the best schools in the land, even though they weren’t rich, because in a generous America you don’t have to be rich to achieve your potential. Theyre both passed away now. And yet, I know that on this night they look down on me with great pride. They stand here, and I stand here today, grateful for the diversity of my heritage, aware that my parents’ dreams live on in my two precious daughters. I stand here knowing that my story is part of the larger American story, that I owe a debt to all of those who came before me, and that, in no other country on earth, is my story even possible. Tonight, we gather to affirm the greatness of our Nation not because of the height of our skyscrapers, or the power of our military, or the size of our economy. Our pride is based on a very simple premise, summed up in a declaration made over two hundred years ago: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are Life, Liberty and the pursuit of Happiness. That is the true genius of America, a faith a faith in simple dreams, an insistence on small miracles; that we can tuck in our children at night and know that they are fed and clothed and safe from harm; that we can say what we think, write what we think, without hearing a sudden knock on the door; that we can have an idea and start our own business without paying a bribe; that we can participate in the political process without fear of retribution, and that our votes will be counted at least most of the time. This year, in this election we are called to reaffirm our values and our commitments, to hold them against a hard reality and see how were measuring up to the legacy of our forbearers and the promise of future generations. And fellow Americans, Democrats, Republicans, Independents, I say to you tonight: We have more work to do more work to do for the workers I met in Galesburg, Illinois, who are losing their union jobs at the Maytag plant that’s moving to Mexico, and now are having to compete with their own children for jobs that pay seven bucks an hour; more to do for the father that I met who was losing his job and choking back the tears, wondering how he would pay 4500 dollars a month for the drugs his son needs without the health benefits that he counted on; more to do for the young woman in East St. Louis, and thousands more like her, who has the grades, has the drive, has the will, but doesn’t have the money to go to college. Now, don’t get me wrong. The people I meet in small towns and big cities, in diners and office parks they don’t expect government to solve all their problems. They know they have to work hard to get ahead, and they want to. Go into the collar counties around Chicago, and people will tell you they don’t want their tax money wasted, by a welfare agency or by the Pentagon. Go in Go into any inner city neighborhood, and folks will tell you that government alone can’t teach our kids to learn; they know that parents have to teach, that children can’t achieve unless we raise their expectations and turn off the television sets and eradicate the slander that says a black youth with a book is acting white. They know those things. People don’t expect People dont expect government to solve all their problems. But they sense, deep in their bones, that with just a slight change in priorities, we can make sure that every child in America has a decent shot at life, and that the doors of opportunity remain open to all. They know we can do better. And they want that choice. In this election, we offer that choice. Our Party has chosen a man to lead us who embodies the best this country has to offer. And that man is John Kerry. John Kerry understands the ideals of community, faith, and service because they’ve defined his life. From his heroic service to Vietnam, to his years as a prosecutor and lieutenant governor, through two decades in the United States Senate, hes devoted himself to this country. Again and again, we’ve seen him make tough choices when easier ones were available. His values and his record affirm what is best in us. John Kerry believes in an America where hard work is rewarded; so instead of offering tax breaks to companies shipping jobs overseas, he offers them to companies creating jobs here at home. John Kerry believes in an America where all Americans can afford the same health coverage our politicians in Washington have for themselves. John Kerry believes in energy independence, so we aren’t held hostage to the profits of oil companies, or the sabotage of foreign oil fields. John Kerry believes in the Constitutional freedoms that have made our country the envy of the world, and he will never sacrifice our basic liberties, nor use faith as a wedge to divide us. And John Kerry believes that in a dangerous world war must be an option sometimes, but it should never be the first option. You know, a while back awhile back I met a young man named Shamus in a V.F.W. Hall in East Moline, Illinois. He was a good-looking kid six two, six three, clear eyed, with an easy smile. He told me he’d joined the Marines and was heading to Iraq the following week. And as I listened to him explain why he’d enlisted, the absolute faith he had in our country and its leaders, his devotion to duty and service, I thought this young man was all that any of us might ever hope for in a child. But then I asked myself, Are we serving Shamus as well as he is serving us? I thought of the 900 men and women sons and daughters, husbands and wives, friends and neighbors, who won’t be returning to their own hometowns. I thought of the families I’ve met who were struggling to get by without a loved one’s full income, or whose loved ones had returned with a limb missing or nerves shattered, but still lacked long-term health benefits because they were Reservists. When we send our young men and women into harm’s way, we have a solemn obligation not to fudge the numbers or shade the truth about why they’re going, to care for their families while they’re gone, to tend to the soldiers upon their return, and to never ever go to war without enough troops to win the war, secure the peace, and earn the respect of the world. Now Now let me be clear. Let me be clear. We have real enemies in the world. These enemies must be found. They must be pursued. And they must be defeated. John Kerry knows this. And just as Lieutenant Kerry did not hesitate to risk his life to protect the men who served with him in Vietnam, President Kerry will not hesitate one moment to use our military might to keep America safe and secure. John Kerry believes in America. And he knows that it’s not enough for just some of us to prosper for alongside our famous individualism, there’s another ingredient in the American saga, a belief that we’re all connected as one people. If there is a child on the south side of Chicago who can’t read, that matters to me, even if it’s not my child. If there is a senior citizen somewhere who can’t pay for their prescription drugs, and having to choose between medicine and the rent, that makes my life poorer, even if it’s not my grandparent. If there’s an Arab American family being rounded up without benefit of an attorney or due process, that threatens my civil liberties. It is that fundamental belief It is that fundamental belief: I am my brother’s keeper. I am my sister’s keeper that makes this country work. It’s what allows us to pursue our individual dreams and yet still come together as one American family. E pluribus unum: Out of many, one. Now even as we speak, there are those who are preparing to divide us the spin masters, the negative ad peddlers who embrace the politics of anything goes. Well, I say to them tonight, there is not a liberal America and a conservative America there is the United States of America. There is not a Black America and a White America and Latino America and Asian America there’s the United States of America. The pundits, the pundits like to slice-and-dice our country into red states and blue states; red states for Republicans, blue states for Democrats. But I’ve got news for them, too. We worship an awesome God in the blue states, and we don’t like federal agents poking around in our libraries in the red states. We coach Little League in the blue states and yes, we’ve got some gay friends in the red states. There are patriots who opposed the war in Iraq and there are patriots who supported the war in Iraq. We are one people, all of us pledging allegiance to the stars and stripes, all of us defending the United States of America. In the end In the end In the end, that’s what this election is about. Do we participate in a politics of cynicism or do we participate in a politics of hope? John Kerry calls on us to hope. John Edwards calls on us to hope. I’m not talking about blind optimism here the almost willful ignorance that thinks unemployment will go away if we just don’t think about it, or the health care crisis will solve itself if we just ignore it. That’s not what I’m talking about. I’m talking about something more substantial. It’s the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores; the hope of a young naval lieutenant bravely patrolling the Mekong Delta; the hope of a millworker’s son who dares to defy the odds; the hope of a skinny kid with a funny name who believes that America has a place for him, too. Hope Hope in the face of difficulty. Hope in the face of uncertainty. The audacity of hope! In the end, that is God’s greatest gift to us, the bedrock of this nation. A belief in things not seen. A belief that there are better days ahead. I believe that we can give our middle class relief and provide working families with a road to opportunity. I believe we can provide jobs to the jobless, homes to the homeless, and reclaim young people in cities across America from violence and despair. I believe that we have a righteous wind at our backs and that as we stand on the crossroads of history, we can make the right choices, and meet the challenges that face us. America! Tonight, if you feel the same energy that I do, if you feel the same urgency that I do, if you feel the same passion that I do, if you feel the same hopefulness that I do if we do what we must do, then I have no doubt that all across the country, from Florida to Oregon, from Washington to Maine, the people will rise up in November, and John Kerry will be sworn in as President, and John Edwards will be sworn in as Vice President, and this country will reclaim its promise, and out of this long political darkness a brighter day will come. Thank you very much everybody. God bless you. Thank you. Also in this database: Barack Obama Announcement for the U.S. Presidency Barack Obama Victory Speech

Job Design as a Motivational Tool - Essay Example Job enrichment is the practice of enhancing job content by building into it more motivating factors such as responsibility, achievement, recognition, and personal growth (Schermerhorn & Hunt & Osborn). A small business owner depends a lot on the output of their staff since resources are limited. The employees must be empowered by the owner in order to get more out these employees. The job enrichment strategy can be used effectively by proving the employee with higher level of involvement in the everyday activities of the business so that the employee feels that the overall performance of the company is highly dependent of the work the person is performing. Job enlargement increases the variety of tasks by combining two or more jobs into job description that used to be performed by different set of workers. This is a very typical scenario in a small business. Sometimes the accountant is also the marketing executives. The small business owner can use this strategy, but the owner must m ake sure the employee is being compensated adequately in financial terms so that the person does not feel he / she is being exploited. Job rotation is a work layout technique that involves a horizontal approach which involves the periodical shifting or rotating of employees into different job tasks.

Employees get motivated when the manager gives them different tasks to perform because the monotony of repetitive work tasks is eliminated. Employees enjoy working in a place where their time needs are part of the equation. A system that provides the flexibility employees desired is flextime. Flextime is a job design system that allows the employee to select the time he or she will
