Homoeostasis - Case Study Example Any fluctuation in the blood glucose concentration is detected by the pancreas, which in turn responds by secreting insulin. The secreted insulin increases the conversion of glucose to glycogen. As a result, Mary’s blood glucose concentration reduces (IHW 2006). Trekking causes excess loss of water from the body in the form of sweat. As a result, the osmolality of the blood plasma rises. The increasing osmolality (stimulus) of the plasma is detected by the hypothalamus (receptor/coordinating center), triggering the secretion of ADH. ADH (effector) causes the opening of aquaporin channels in the collecting ducts of the kidney. In the process, more water is reabsorbed from the urine into the bloodstream. The reabsorption of more water (response) reduces the osmolality of the plasma. However, if alcohol is ingested, it inhibits the secretion of ADH, making the aquaporin channels to close. As a result, the body loses more water in the form of dilute urine (MMHE n.d., p. 1192). Since Jason had put on a short sleeve shirt, the peripheral nerve receptors in his skin detected the surrounding temperature and relayed an appropriate message to the hypothalamus. The hypothalamus in turn stimulated his skeletal muscles, causing him to shiver. Although the shivering generated heat by friction, it was not sufficient to normalize Jason’s body temperature. However, when Jason decided to run, the activity in his muscles intensified and generated sufficient heat to keep him warm. As a result, the shivering stopped because his body had gained the necessary heat (Docherty & Foudy 2006, p. 20). Dampney, RAL, et al. (2006).

Environmental Speech Essay Example for Free

Environmental Speech Essay My speech will be about Global warming, this is the rise in the average temperature of the Earth’s atmosphere and oceans. In 2011 the emission of carbon dioxide and was the highest it had ever been before and it had also taken a similar jump in 2012. Over all, emissions of carbon dioxide had jumped 3 percent in 2011 and in 2012 it was estimated that it had jumped another 2. 6% in 2012. Scientists are 90% sure that Humans are the cause global warming from producing greenhouse gases produced by human activity like using a car which is burning fossil fuels and also is caused deforestation. Since the early 20th century the Earth’s average temperature has increased by 0. 8 degrees centigrade. The effect of an increased temperature will result in the rise of sea levels. Global warming is strongest in the arctic and causes a more frequent occurrence of extreme weather events such as heat waves, heavy rainfall, droughts and species extinction. How do we stop Global Warming? Turning the thermostat down a few degrees can make a big difference in decreasing our carbon dioxide emissions. Replacing a regular light bulb with compact florescent lights will save you ? 15 over the life of the bulb and reduce global warming. Driving less and using public transport more often will reduce the carbon dioxide from the burning of fossil fuels which are burnt every day from transportation vehicles. Decorating your house with plants and trees will help as they take in carbon dioxide and produce oxygen.

Simon as Silent Prophet of Lord Of The Flies Essay -- Lord Flies Essay

Simon as Silent Prophet of Lord Of The Flies  Ã‚        Ã‚  Ã‚  Ã‚  Ã‚   The role of the prophet changes with the society in which he lives. In Modern America, a prophet is a visionary, telling his people what they can become; in Biblical times, a prophet was the voice of God, telling his people what they had to become to fulfill their covenant with God. In William Golding's Lord of the Flies, though, the prophet told his people nothing; he realized what they had already become, and he dared not tell them because he knew they would turn against him. Simon lived in knowledge and fear because his society denied the role of the prophet, and he did not fight it because he wanted so much to be part of that society.    The basic premise of Lord of the Flies is that humans naturally live in savagery and ignorance, without any idea of how to live together. It is the story of boys stranded on an island who must develop a government to survive. Every detail of the story holds symbolism. For example, each character represents an aspect of society : those who represent human nature survive, and those who are self-actualized--the scientists, the religious, the leaders--all die. The most terrifying death is that of Simon, who symbolizes the eyes of a blindfolded and stumbling people. He alone saw that the jungle, which represented freedom and the lack of civilization, was not to be feared but to be understood; he alone knew that the mythical Beast of the island, feared by all the boys, was in fact their own inherent savagery. (The title, Lord of the Flies, is in fact a translation of "Beelzebub," a name of the devil in the Judeo-Christian tradition).    In a vision, the Beast told Simon: "Fancy thinking the Beast was something you could hu... ... his fear, his compatriots' savagery justifies that weakness. If his flaw was his desire to be accepted, then he was no different from any of the other boys. Simon was just as human as all the children on the island, abandoned to "the end of innocence, the darkness of man's heart" (202). If the truth died with Simon, it died because human nature hates prophets, because humans naturally live in savagery and ignorance.    Works Cited Epstein, E.L. "Note on Lord of the Flies."

Devised self-Evaluation

Our first unit of work in the IGCSE was Devised theatre. Our theme was â€Å"The unexpected† and we chose this title because there is an always unexpected things that happens in our life. Our play is about a person who once had a family, job, and life, but after he got fired he loses everything. Then later on in the story a devil and an angel appears giving him idea of earning money. At last the person choses the Devils way instead of the angel’s way of earning money. The devils way of earning money is to wear his old uniform and pretend to be the manager of the supermarket. Then steal the money and walk away. The plan does not go as expectation. All things went wrong. At last nobody wants to help him, even the angel and devil did not want to help him. He even got someone in jail. Our group used the theme to create a 10 minute play exploring on unexpected events. We went about process by firstly planning the events that is going to happen in our play and then think of things that could go wrong in the story. We first started with the idea of a person who is desperate in need of money. Then we changed it gradually bit by bit, until we are satisfied. Input was shared equally by all members of the group by sharing different ideas and contributing to the group. Each member had contributed something to the group. Some people contributed props, equipment, ideas, and etc. Before the start of the performance I felt really nervous and i also excited about that I was going to perform in front of many parents and peers. It was also the first time I had to perform in the public. I try to overcome these emotions by telling myself not to panic and by staying in role during the performance. In my performance, I portrayed myself as an old granny and a little boy. I tried to communicate this character through the use of my tone, clarity, enunciation, volume, gesture †¦ I thought I was able to effectively use my tone, body gesture, and facial expression to create a sense of humor during the performance. For example, I had a hunched back gesture and a cranky voice, when I was being the grandmother. I stayed in role during the performance. I think I need to improve on having more eye contact toward the audience. I admired Andy’s group mainly of their use of comedy and humor. Their exploration of how they used their vocals, and how they used their body gesture was really outstanding during the performance. In conclusion, I think as a group we work quite well and I think our performance was quite successful, but I think there are some improvements to be done. The targets for our devised theatre are that we have to be more confident on contributing ideas to each other. Finally, the target for my performance skills is that i should more eye contact toward the audience.

Information Technology Management Essay

Information and communication technologies play critical roles in sustaining an organizations growth and profitability (Galliers & Leidner, 2003). If managed properly, investments in information and communication technologies can improve efficiency and effectiveness of business processes and an organization’s competitive posture in the market. Proper management of information and communication technologies investments can also enrich people’s lives in the organization improving job satisfaction and productivity. Galliers & Leidner, 2003). Success in managing information and communication investments depend largely on exercising good management practices like human capital management, staff training management, information technology architecture management and software management (Galliers & Leidner, 2003). However, with all the potential benefits of investments in information and communication projects, they can be risky, costly and unproductive if not managed properly (Galliers & Leidner, 2003). Organizations should therefore strive to attract and retain information technology personnel that are qualified and talented to ensure the success of information and technology investments. This is further complicated by a tight information and technology labor market where qualified information and technology personnel enjoy high mobility. Discussion The position I am required to design is a leadership position intended to provide technical direction and guide an organization in implementing strategic information and communication projects (Food and Agriculture organization of the United Nations, 2010). The occupant of this position is expected to be able to handle a wide range of duties and responsibilities. He or she should be able to use his/ her exposure, technical experience and business knowledge in developing an organization’s technical plans and to advise senior management on information technology strategies, standards and governance (Galliers & Leidner, 2003). In addition he or she will be expected to monitor the industry’s trends in information technology and respond appropriately by formulating long term information technology strategies capable of improving an organization’s competitiveness. The senior information technology manager will work under the general supervision of the chief executive officer. In line with work plans and resource allocation coordination provided by the chief executive officer, he or she will be responsible for effective planning, supervision and delivery of assigned functions that fall within an information and communication department (Food and Agriculture organization of the United Nations, 2010) so as to ensure that an organization’s requirements for information systems and information technology are effectively and efficiently met. He will also be responsibility for ensuring that an organization’s computer systems have the capacity to meet the business needs of an organization by either upgrading existing systems or developing new systems (Info Tech Employment, 2008). Additional functions will include participation in planning, coordinating and setting policies for the development and implementation of an organization’s information technology strategies, supporting standards, procedures and practices, supervising and coordinating works of external firms in special projects or functions to ensure quality and timely delivery, providing consultant services in regards to procurement of new information technology equipments and computer systems, supervising members of staff assigned to special projects or functions and coordinating their training and development to ensure that they are up to the tasks and finally, developing and monitoring key performance indicators of assigned functions within an information technology department (Food and Agriculture organization of the United Nations, 2010). The senior information technology manager is expected to have an excellent working knowledge in information technology and a commitment to keep up to dat e with the latest development (Galliers & Leidner, 2003). He should demonstrate people’s management skills with an ability to motivate staff members, provide a cooperative and productive work environment, manage resources effectively to achieve objectives, organize and coordinate work in the department and explain technical issues clearly (Info Tech Employment, 2008). He or she will be tasked with leading changes that fall within the information technology department, hence must be able to integrate organizational and departmental goals, priorities and values. In addition, he or she should have experience in managing large scale projects in information systems and technology (Food and Agriculture organization of the United Nations, 2010). To fulfill these expectations, a university degree in computer science or related fields and appropriate professional certifications are mandatory. Moreover, the candidate of choice should have at least five years management experience in information technology. He should demonstrate experience with standard software applications and data manipulation, analysis and interpretation tools (Food and Agriculture organization of the United Nations, 2010). Conclusion Information technology investments can be very beneficial to an organization as a whole if they are managed properly. Organizations should therefore strive to hire and retain qualified, experienced and talented information technology managers. This is not easy given the current information technology labor market. The labor market is characterized by high mobility of qualified labor and organizations must put in place effective measures to ensure they hire the right people. One of the measures an organization should take is defining clear structures and responsibilities of all employees in the information technology department. The senior information technology manager will provide technical direction and guidance to the organization in implementing strategic information technology projects. He will be responsible for ensuring effective and efficient management of resources within the information technology department.

Commitments Essays - English-language Films, Films, The Commitments

Commitments Essays - English-language Films, Films, The Commitments Commitments Have you ever watched a movie and then watched it over again just for the music? If this is a common occurrence for you, then get your rewinder ready for The Commitments. It's not often that a movie comes along with a soundtrack as good as this one's. The music is an integral part of the movie, but it's not all that makes this movie worth seeing. The cast was put together like a tight fitting puzzle. The writers worked in the necessary comedic elements, while also showing the characters' strengths and weaknesses. It's not often you see a movie about music come along where someone doesn't die, or the same song isn't played over and over again. With songs like Mustang Sally, the Black Crowe's' hit Hard to Handle, and Chain of Fools, this soundtrack really rocks. It's hard to believe that Andrew Strong, who played Deco Cuffe in the film, was only sixteen when this movie was made. His voice oozes power and emotion, a feat not easily accomplished by even an experienced singer. He is truly Joey Lang's Irish counter-part. The group's rendition of Try a Little Tenderness was nothing less spectacular. The Commitment-etts, played by Angelina Ball, Maria Doyle, and Bronagh Gallagher, added their talents primarily as back-up singers, but they do have some spotlight numbers. Their style, the choreography and harmonies, reminds me of some of the girl groups from the Fifties and Sixties: The Supremes, the Shirrelles, and the Marvelettes. While in the movie Chain of Fools is interrupted by a fight, the girls pull off the performance masterfully. The Commitments is found in the Drama section at Blockbuster Video, but I found it to be more of a comedy than a drama. When Joey Fagen, played by Johnny Murphy, is introduced, I had a good laugh as he crashed his scooter in the alley. My favorite part of the movie is a conversation between Jimmy Rabbit (Robert Arkins) and his father, played by Colm Meaney. After Jimmy had spoken with Joey at the back gate, his father asked, What did he want? Jimmy replied with the answer he had been given, God sent him. Mr. Rabbit had to ask again to make sure he heard right, and he got the same answer, to which he replied this time, On a Suzuki? It's not just the dialogue that makes this movie funny. Some of Deco's onstage antics are notably laugh-worthy: knocking over the Commitment-ettes and electrocuting Outspan (Glen Hansard. The writers even added the never fails to get a laugh fart in a small cramped space. Even with all of his comedic scenes, Deco is more than just comic relief in this movie. For the most part, he is shown as an egotistical jerk. He has a great voice, and he knows it, and the writers let him show it. He even goes as far as saying, This is my band, which none of the others take too lightly. Joey is another character with some depth to him. He is the religious one to whom God said, The Irish brothers need some soul. With all of his Bible spouting, Joey's actions are less than holy. He is the only male member of the band who's having sex, and it happened to be with each of the Commitment-etts. Jimmy Rabbit is the band's manager, and perhaps one of the most complex characters in the film. At first, it seems he believes the band is just another moneymaking scheme. When things started coming together in the group's performances, I believe he started to see The Commitments as his way to fame. He would hold imaginary interviews with himself, and give the reporters deep-seeming responses when actually interviewed. He had spent two years receiving unemployment benefits, and I think that he wanted more, which where the band fit into his plans. I wouldn't say that The Commitments fits into either the Death Watch genre of rock-n-roll films, or the Sex Watch. I think that it may fall into the class of Could Be Big rock-n-roll films. Another film in this category would That Thing You Do, the 1996 Tom Hanks film. These films are alike in many ways. The band members in

What to Bring to the SAT and What Not to Bring

What to Bring to the SAT and What Not to Bring SAT / ACT Prep Online Guides and Tips After months of planning and prepping, test day is finally upon you! What exactly do you need to bring to the SAT- and what should you just leave home? We’ll talk about what to bring to the SAT for certain and some not so obvious things that might come in handy. Make sure your bag is packed and ready to go so you can focus on performing your best- and not on tracking down a pencil sharpener! What to Bring on SAT Day: The 4 Essentials First things first: what must you bring to the SAT? Here are the four essentials you cannot afford to forget on test day: #1: Admission Ticket You must print out your admission ticket and bring it to the testing center. A paper copy of your ticket is 100% necessary for admission- you can't show it on your cell phone, tablet, etc. To print it out, log into your College Board account and click on "Print Admission Ticket." #2: Photo ID Your photo ID should resemble the picture you uploaded to the College Board website when you registered for the SAT. Below is a list of acceptable and unacceptable forms of ID: Unexpired government-issued IDs (e.g., driver’s license, passport, military ID, national ID, etc.) Current school ID card Student ID Form, if you don’t have any of the other forms; this form must be prepared by the school you currently attend or by a notary if you are home-schooled Unacceptable IDs include IDs that are expired or damaged or do not match your College Board photo. Some unacceptable forms of ID include the following: Credit or debit cards (even ones with photographs) Birth certificates Social Security cards Employee ID cards ChildFind ID cards Other temporary ID cards #3: At Least Two #2 Pencils and an Eraser Pens, highlighters, liquid paper, or any other writing utensils are not allowed,not even for the essay (if you're taking the SAT with Essay). Check your erasers to make sure they work well. #4: An Acceptable Calculator You'll need to bring your own calculator for the Math Calculator section. Acceptable calculators include graphing and scientific calculators. A basic four-function calculator is also allowed but not recommended. Learn all about the uses and limitations of your calculatorwith our guide. Unacceptable calculators and devices include the following: Laptops Tablets Cell phones Calculators that make noise or use a keyboard-like (QWERTY) keypad, an electrical outlet, or a paper tape Basically, don’t bring anything that could be disruptive or has communication capabilities. As long as you have these four items- your admission ticket, your ID, pencils/erasers, and an approved calculator- you should have no trouble being admitted into the SAT. Now that you know things to bring to the SAT, let’s consider a few other materials that might help you out during the test. Other Items You Might Want to Bring to the SAT In addition to the four essentials, what other items can you bring to the SAT? Here are some of our recommendations for things that might come in handy on SAT test day: Extra #2 pencils and a small handheld pencil sharpener. Since time is tight and talking is prohibited, you definitely don’t want to find yourself in the middle of the SAT with nothing to write with! So bring some backup writing utensils and a sharpener. Extra batteries for your calculator, just in case. It’s also a good idea to put in new batteries the day or two before the SAT- and definitely make sure that your calculator works! A drink and snacks for your breaks. These will likely have to stay in your bag, in a locker, or up at the test administrator’s desk and will have to be consumed outside of the testing room. The SAT is a long test; drinks and snacks will help you stay hydrated, energized, and focused. A watch,as long as it doesn’t have any audible alarms or noises. If it'll help you keep track of time, bring one along. If you just find it distracting, though, leave it at home! These extras and backup materials might prove helpful the day of the SAT. Now, whatshould you definitely not bring on SAT test day? What NOT to Bring to the SAT There are lots of prohibited items when it comes to SAT test day. We’ll list a few below, butyour best bet is to avoid bringing anything that’s not recommended on the above lists: Any other technology besides your calculator, especially anything with communication or recording capabilities. This means no cell phones, laptops, tablets, timers, cameras, or audio recorders. The College Board takes security very seriously, as you can tell from these high-profile cheating scandals. Any other notes,cheat sheets, dictionaries, translators, books, or papers. To reiterate, if you must bring your cell phone, turn it off well before the test. If it beeps even just once, your proctor will confiscate it and cancel your test immediately. Want to learn more about the SAT but tired of reading blog articles?

Getting Ready for SAT Test Day: 5 Key Tips Now that you know exactly what to bring (and not bring) to the SAT, how can you ensure that you are prepared to do your best on the test? Read on to learn how you can have a great SAT test day: #1: Prepare Ahead of Time Get all your materials gathered and packed the day before your test. You definitely don’t want to be scrambling in the morning trying to track down pencils and batteries for your calculator. This would cause a whole lot of unnecessary anxiety and could make you late (and therefore ineligible) for the test! So get everything taken care of at least the day before. #2: Test Your Calculator Before the SAT, check that your calculator is working properly. Test out the different functions, and put new batteries in it so that it won't have any chance of dying during the test! #3: Print Out Multiple Copies of Your Admission Ticket It's a good idea to print out a few copies of your SAT admission ticket, just in case. If you don’t have a printer, you can get this taken care of at school, your local library, or another printing center such as Staples. Remember that you will not be admitted on test day without this ticket. As mentioned above,don’t wait until the morning of or late the night before the SAT to print out your ticket. It’s a strange and inexplicable rule of printers that they tend to malfunction right before a big test or due date. So print out two or three copies early and save yourself the hassle! #4: Practice Self-Care Self-care is important in general but especially in the days leading up to the SAT. The morning of the test, eat a healthy breakfast. Exercising the day before (and in general) might also aid in easing your stress levels and clearing your mind. Don’t underestimate the power of diet and exercise in feeling good and thinking clearly! #5: Double-Check That You've Got Everything You Need Finally, make a checklist and double-check your bag one last time before you head to your testing center. After all your preparation, your focus should be wholly on the SAT. By having all these materials taken care of, you'll be poised to perform your best! What’s Next?
