Gastroesophageal Reflux Disease - Case Study Example Heartburn is a common symptom for GERD. Other symptoms may occur less frequently though indicative of GERD including: acid regurgitation, excess saliva, chronic sore throat, chest pain, gum inflammation, chronic sore throat and chest pain. Harsh stomach acids can damage the esophageal lining. Reflux risk factors include alcohol use, pregnancy, obesity and smoking. Reflux and heartburn are worsened by pregnancy. Asthmatic people have higher risks of developing GERD. Flare-ups of asthma cause the lower esophageal sphincter (LES) to relax, therefore allowing the backflow of stomach contents into the esophagus. Asthma medications worsen reflux symptoms (Joel & Ritcher, 2014). Acid reflux may also make the symptoms of asthma worsen through irritating the lungs and the airways, leading to more serious asthma. However, the following is a patient education plan that focuses on conservation measures in treating GERD. Decreasing the portion size at mealtime may be helpful in controlling symptoms. Taking meals 2-3 hours prior to bedtime may aid in lessening reflux through decreasing stomach acid and emptying it partially. Additionally, being overweight is often associated with worse symptoms of GERD. Overweight patients should find relief in losing some of their weight (Gary, 2008). Moderate exercise is considered to improve GERD symptoms, but vigorous exercises may worsen the symptoms. Moreover, when sleeping, the patient is advised to elevate the head of the bed at least 6-8 inches, or to sleep on a wedge-shaped bed that is specially designed. This reduces heartburn by allowing gravity minimize stomach contents reflux into the esophagus. It is advisable that the patient does not use a pillow to prop him/her up; this only adds pressure on the stomach, worsening the situation. Cigarette smoking and taking and alcohol usually weakens the LES. Symptoms of GERD may be reduced by halting smoking and stopping alcohol taking behavior. Along with diet and lifestyle

Platos Apology Of Socrates Essay Example for Free

Platos Apology Of Socrates Essay INTRODUCTION Plato makes it clear, especially in his Apology of Socrates, that he was one of Socrates’ devoted young followers. In that dialogue, Socrates is presented as mentioning Plato by name as one of those youths close enough to him to have been corrupted, if he were in fact guilty of corrupting the youth,[1] and questioning why their fathers and brothers did not step forward to testify against him if he was indeed guilty of such a crime. The relationship between Plato and Socrates is not unproblematic. The charges against Socrates says that he has two sets of accusations: the old, longstanding charges that he is a criminal, a busybody, and a curious person who makes inquiries into the earth and sky, and the recent legal charges that he is guilty of corrupting the young, and of believing in supernatural things of his own invention instead of the gods recognized by the State.[2] Which he terms as charges stemmed from years of gossip and prejudice against him and hence was unanswerable. The trial of Socrates is the central, unifying event of the great Platonic dialogues.   The causes that occasioned this Apology were as follow: Aristophanes, at the instigation of Mellitus, undertook, in his comedy of the clouds, to ridicule the venerable character of Socrates, on the stage; and the way being once open to calumny and defamation, the fickle and licentious populace paid no reverence to the philosopher, whom they had before regarded as a being of a superior order.[3] When this had succeeded, Melitus stood forth to criminate him, together with Anytus and Lycon; and the philosopher was summoned before the tribunal of the Five Hundred. He was accused of making innovations in the religion of his country, and corrupting the youth. However, as both these accusations must have been obviously false to an unprejudiced tribunal, the accusers relied for the success of their cause on perjured witnesses, and the envy of the judges, whose ignorance would readily yield to misrepresentation, and be influenced and guided by false eloquence and fraudulent arts. In the Apology, Socrates tries to dismiss rumors that he is a sophist and defends himself against charges of disbelief in the gods and corruption of the young. Socrates insists that long-standing slander will be the real cause of his demise, and says the legal charges are essentially false. Socrates famously denies being wise, and explains how his life as a philosopher was launched by the oracle at Delphi. He says that his quest to resolve the riddle of the oracle put him at odds with his fellow man, and that this is the reason he has been mistaken for a menace to the city-state of Athens. THE APOLOGY of SOCRATES Socrates begins by saying he does not know if the men of Athens (his jury) translation often says â€Å"gentlemen,† have been persuaded by his accusers.[4] Plato often begins his Socratic dialogues with words that indicate the overall idea of the dialogue; in this case, I do not know. Indeed, in the Apology Socrates will suggest that philosophy consists entirely of a sincere admission of ignorance, and that whatever wisdom he has, comes from his knowledge that he knows nothing. Socrates asks the jury to judge him not by his oratorical skills, but by the truth. Socrates says he will not use ornate words and phrases that are carefully arranged, but will speak the chance thoughts that come into his head. I know not, O Athenians, how my accusers may affect you: I indeed have through them almost forgotten myself, so persuasively have they spoken; though, as I may say, they have not asserted any thing, which is true. However, among the multitude of their false assertions I am most surprised at this, in which they say that you ought to beware of being deceived by me, as if I were an eloquent speaker. For that, they should not be ashamed of asserting that which I will immediately confute in reality, since in the present instance I shall appear to you to be by no means eloquent, this seems to me to be the consummation of impudence; unless they call him eloquent who speaks the truth. The three men who brought the charges against Socrates were Anytus, son of a prominent Athenian, Anthemion. Anytus makes an important cameo appearance in Meno. Anytus appears unexpectedly while Socrates and Meno are discussing the acquisition of virtue. Having taken the position that virtue cannot be taught, Socrates adduces as evidence for this that many prominent Athenians have produced son’s inferior to themselves. Socrates says this, and then proceeds to name names, including Pericles and Thucydides. Anytus becomes very offended, and warns Socrates that running people down could get him into trouble someday. Meletus, the only accuser to speak during Socrates’ defense. He is mentioned in another dialog, Euthyphro, but does not appear in person. Socrates says there that Meletus is a young unknown with hooknose. In the Apology, Meletus allows himself to be cross-examined by Socrates and stumbles into a trap. Apparently not paying attention to the very charges he is bringing, he accuses Socrates of atheism and apparently, of believing in demi-gods. Lycon, about whom little is known; he was, according to Socrates, a representative of the orators. O Athenian, I should answer the first false accusations of me, and my first accusers, Socrates claims to never have been a teacher, in the sense of imparting knowledge to others. He cannot therefore be held responsible if any citizen turns bad. If he has corrupted anyone, why have they not come forward to be witnesses? Alternatively, if they do not realize that they have been corrupted, why have their relatives not stepped forward on their behalf? Many relatives of the young men associated with him, Socrates points out, are presently in the courtroom to support him.[5] For many have been accusers of me to you for many years, and who have asserted nothing true, of whom I am more afraid than of Anytus and his accomplices, though these indeed are powerful in persuading; but those are still more so, who having been conversant with many of you from infancy, have persuaded you, and accused me falsely.[6] For they have said, that there is one Socrates, a wise man, studious of things on high, and exploring every thing under the earth, and of believing in supernatural things of his own invention instead of the gods recognized by the State. These men, O Athenians, who spread this report, are my dire accusers. For those who hear it think that such as investigate these things do not believe that there are gods.[7] In the next place, these accusers are numerous, and have accused me for a long time. They also said these things to you in that age in which you would most readily believe them, some of you being boys and lads; and they accused me quietly, no one speaking in my defence. Such however, as have persuaded you by employing envy and calumny, together with those who being persuaded themselves have persuaded others. Consider, therefore, as I have said, that my accusers are twofold, some having accused me lately, and others formerly; and think that it is necessary I should answer the latter of these first; for you also have heard these my accusers, and much more than you have those by whom I have been recently accused. Be it so. I must defend myself then, O Athenians, and endeavor in this so short a space of time to remove from you the calumny that you have so long entertained. I wish, therefore, that this defence may effect something better both for you and me, and that it may contribute to some more important end. I think however that it will be attended with difficulty, and I am not entirely ignorant what the difficulty is. At the same time let this terminate as Divinity pleases. It is my business to obey the law, and to make my apology.[8] Conclusion Socrates concludes this part of the Apology by reminding the jurors that he will not resort to the usual emotive tricks and arguments. He will not break down in tears, nor will he produce his three sons in the hope of swaying the jurors. He does not fear death; nor will he act in a way contrary to his religious duty. He will rely solely on sound argument and the truth to present his case.[9]Socrates punishment speech angered the jurors. 360 of them voted for the death penalty; only 141 voted for a fine of 3,000 drachmae. Now Socrates has to respond to the verdict. He first addresses those who voted for death. He claims that it is not a lack of arguments that has resulted in his condemnation, but rather his unwillingness to stoop to the usual emotive appeals expected of any defendant facing death. Again, he insists that the prospect of death does not absolve one from following the path of goodness and truth. To those who voted for his acquittal, Socrates gives them encouragement: He says that his daimon did not stop him from conducting his defence in the way that he did as a sign that it was the right thing to do. Therefore, death must be a blessing. It is either an annihilation (thus bringing eternal peace from all worries, and therefore not something to be truly afraid of) or a migration to another place to meet souls of famous people such as Hesiod and Homer and heroes like Odysseus. With these, Socrates can continue his task of questioning. Bibliography Leo Strauss. Socrates and Aristophanic. New York, 1966.

Biology Essays Heart Disease

Biology Essays Heart Disease The Biological Basis and Risk Factors for Coronary Heart Disease. Coronary heart disease is a blanket term which describes all types of heart disease caused by blockage of the arteries that supply blood to the heart. Lack of sufficient blood is associated with a lack of oxygen, also called ischemia. Hence coronary heart disease is also called ischemic heart disease. Angina, heart attack and heart failure and are all clinical forms of coronary heart disease.1 Overall, coronary heart disease is the leading cause of death in the Western world.2 In the UK, heart attacks are responsible for around 150,000 deaths every year and cost the NHS approximately  £719 million per year. Almost half of all heart attack sufferers die within 20 days of the attack.3 The heart of the problem The heart is a vital organ, pumping blood which carries essential oxygen and nutrients all around the body. As a powerfully active muscle, the heart needs a ready and plentiful supply of oxygen and nutrients itself; however these are not extracted from the blood that flows through it. Instead, the heart has its own specific blood supply – the coronary arteries. There are two major coronary arteries – the right and left. The volume of blood which flows to the heart is largely determined by the width of these vessels and is not so dependent on the power at which the blood is pumped through them. Unlike other organs which can use the oxygen within veins if needed, the heart is completely reliant on the coronary arteries’ supply. Hence their ability to expand and supply more blood when required is essential.4-6 Coronary heart disease develops when various materials build up within the walls of the coronary arteries causing a narrowing of the vessels and potentially leading to complete blockage. The obstruction of blood flow to the heart which results from this build up within the coronary arteries can cause a range of cardiac problems. When the blood flow to the heart is only temporarily interrupted, usually during exercise and times of exertion when the heart muscle requires more oxygen, the condition is known as angina. A person with angina will experience short attacks of chest pain which usually clear up with rest. Ultimately, insufficient blood flow can result in actual physical damage to the heart tissue. In severe cases, where blood flow is completely blocked, the portion of the heart affected may die from lack of oxygen– this is termed myocardial infarction, commonly known as a heart attack. Symptoms of heart attack include prolonged and severe chest pain, weakness and shortn ess of breath. In rare cases, patients with coronary heart disease experience heart failure. This is a broad condition which describes any symptoms showing that a patient’s heart is not performing as it should. 4-6 Why do coronary arteries become blocked? In healthy arteries, the walls are smooth and blood flows easily. The process leading to the development of coronary heart disease begins with the development of ‘fatty streaks’. These are yellow patches which appear within the wall of the coronary artery. The streaks are made up of a special type of cell called foam cells, which are rich in fats, plus smooth muscle cells. Over time, streaks can turn into plaques. Plaques, also known as atheroma, are fatty lumps which form within the lining of the arteries. There are various different kinds of plaques. Some are made up of a soft inner core of cholesterol covered by a thin firm outer layer. Others are completely solid and composed of smooth muscle cells and various other strong materials. Calcium may also build up on a plaque making the problem worse.4,7 What is the blockage like? Plaques cause several problems to coronary blood flow. Firstly, a plaque itself can be big enough to narrow the artery and reduce the space available for blood to flow through it. Secondly, as blood is thrust against the side of the plaque with each heart beat, the outer shell of the plaque may crack open exposing the cholesterol core. When the cholesterol core is exposed, blood clotting is triggered within the artery. Clots reduce the blood flow even more. This whole process can happen repeatedly causing the artery to become narrower and narrower and eventually leading to complete blockage.4,7 Overall, the process of plaque formation and associated thickening, loss of elasticity and narrowing of the artery walls is known as atherosclerosis. Atherosclerosis is the major cause of coronary heart disease however, it is also present to some degree in almost every adult male in Western societies. What causes atherosclerosis to occur is complex and uncertain and there is much still to learn. Current thinking is that atherosclerosis results from some kind of ‘response to injury’ where initial non-specific injury to the lining of the artery wall triggers the whole process to start up.4,7,8 Risk factors Everyone has some chance of experiencing heart disease, however, various factors have been identified which increase the risk of developing coronary heart disease. These include:4,6,7,8 High cholesterol Smoking Lack of exercise Unhealthy diet Obesity Diabetes High blood pressure (hypertension) Mental stress High levels of certain blood clotting factors Family history Alcohol and coffee Male gender Ethnic group (e.g. Southern Asians in the UK are at higher risk) Most of these risk factors increase the risk of coronary heart disease by increasing the likelihood that atherosclerosis will develop within the coronary arteries themselves. Also, these risk factors have been found to ‘interact’. Hence if you have two or more risk factors your overall chance of developing coronary heart disease is proportionally higher than if you just had one risk factor.8 Heredity as a risk factor Coronary heart disease often occurs within several members of the same family, indicating that a genetic link may be involved. However, it is difficult to determine if the link between family members is due to genes or shared environmental factors, such as diet and exposure to smoke. Genetic factors have been shown to influence cholesterol levels and the amount of blood clotting factors a person has in their blood, which in turn has a knock-on effect on the risk of developing atherosclerosis. Overall, it seems that a combination of genetics and the environment would best explain the family link to heart disease. It has been estimated that 40% of the risk is controlled by genes, and 60% is due to environmental factors.4,6 High cholesterol as a risk factor There are two types of cholesterol found in the blood – ‘good’ HDL cholesterol which can protect against the development of heart disease and ‘bad’ LDL cholesterol which promotes the development of atherosclerosis. There is lots of evidence to show that unhealthy amounts of these two types of fat in the blood, i.e. high LDL and low HDL levels, can increase the chance of developing coronary heart disease. This is because high levels of cholesterol in the blood encourage the formation of plaques within the artery wall and promote the overall process of atheroschlerosis.4,6 The cause of high LDL levels has not been clearly established but dietary factors are likely to be involved. There is evidence that a diet high in saturated, but lacking in polyunsaturated, fat may contribute to high cholesterol levels. There is relatively little actual cholesterol in the diet, but saturated fat is converted into cholesterol in the liver.4,6 Lack of exercise as a risk factor Lack of exercise is a proven risk factor for the development of coronary heart disease. Overall, the risk is a third less in people who exercise compared to those who don’t.8 It seems that physical exercise has a protective effect on the development of coronary heart disease. The mechanism underlying this has not been fully elucidated but certain hypotheses have been put forward. Exercise may increase levels of good HDL cholesterol and also reduce the blood clotting which occurs within atherosclerotic arteries and causes further blockage. Exercise might also help enlarge the coronary arteries and hence increase blood supply to the heart. In order to gain full health benefits from exercise in the reduction of coronary heart disease risk, five bouts of moderate physical activity per week, each lasting a minimum of 30 minutes, are recommended. Conclusion Coronary heart disease is a serious condition caused by the build-up of fatty deposits within the walls of the vital arteries that supply blood to the heart. Coronary heart disease is the major cause of death in Western societies but to a large extent is preventable. Recognising the key risk factors which contribute to the development of atherosclerosis is an important step towards reducing the overall incidence of coronary heart disease.

To Kill A Mocking Bird :: To Kill a Mockingbird Essays

Characters grow and develop and allow us to become a part of their lives in ‘To Kill A Mockingbird’ by Harper Lee. This is true because the story is told from the perception of a young girl called Scout. We get so close to Scout because the whole story is told from her point of view. We share her experiences as she would go through them, we are with her when some of the most important events in her life happen to her, life changing events that can change a person, like being attacked by Bob Ewell and watching her father defend Tom Robinson in court. We learn everything she learns, like why the Ewells and the Cunninghams live the way they live and why Atticus defended Tom Robinson in court. In only the first few pages of the book we learn so much about the town of Maycomb and the people in it, through Scout’s narration. As the book progresses on, we see her grow up and mature, and begin to understand things that she didn’t understand in the beginning e.g. her neighbor Boo. In one of the first few chapters Atticus tells Scout that ‘you never really understand a person until you climb into his skin and walk around in it.’ When he told her this she didn’t understand and take on board what he meant. As the story develops we witness all the events unfolding leading to her standing on Boo Radley’s front porch and fully understanding what Atticus had said. It is here that we realize that Scout has changed and now has different views of the town and the people in it to what she had in the beginning of the story. Jem also grows and develops as a character by the end of the book. We get close to Jem in the story because being Scout’s older brother, he is always with her. Jem is ten in the beginning of the story and the story continues until he is thirteen. He starts out very curious and always asking questions (not as much as Scout though) but he is older. We also witness him go through the same life changing events as Scout, but he has a different perception of them, like when Mrs. Dubose dies, it isn’t a big deal to Scout, but to Jem he learns what real courage is and that is undoubtedly what starts to change him from a boy to a young man.

Obeserving bacteris and blood Essay

Objectives: There were two major goals of the â€Å"Observing Bacteria and Blood† experiment. The first was to establish a familiarity with the proper techniques for using a microscope. The experiment focused on both the basic components of a microscope (i.e. how to adjust the knobs and levers for the desired result) as well as how do decide the proper objective to use for observing a specimen. The second goal major goal of this experiment was to practice observing live specimens (yogurt and blood). Procedures: Exercise 1: Observation of prepared slides using the microscope. The observation of the 8 prepared slides was performed by making adjustments to the microscope (focus, condenser, light) in order to establish a clear image of the specimen. The slide was viewed through the 10x, 40x, and 100x objectives and all observations were recorded in the tables below. Exercise 2&3: Observationof yogurt and blood. The yogurt and blood slides were prepared as described in the Labpaq manual. The slides were observed using the 10x, 40x, and 100x objectives and all observations were recorded in the tables below. Observations/Results: Exercise 1 SampleObservations Part 1Part 2 150x600x1500x (Oil Immersion) Amoeba proteus Anabaena Ascaris Eggs â€Å"e† slide Paramecium Penicillium w/conidia Yeast Yogurt bacteria Exercise 2 & 3 SampleObservations 150X600x1500x Ex 2: Fresh Yogurt Ex 3: Blood Smear Photos/Drawings: (Insert and label images here. If image file (JPEG or GIF) sizes are too large they may be uploaded separately.) Analysis/Interpretation: Based on the observations detailed above, it can be concluded that the microscope is a powerful tool in the observation of organisms that are small in size. It was important to have a number of objectives of different magnifying power in order to be able to discern the level of magnification needed to best study a sample. In addition, the examination of the yogurt sample allowed for the observation of the varying shapes and arrangement of bacterial cells. The use of a microscope to observe the blood smear highlighted the many important components of human blood that are not evident by the naked eye. Application: In performing this experiment I have learned many important aspects of microbiology that apply to healthcare. First, there is plenty of information that can be discovered by looking at a sample under the microscope †¦ size, arrangement, number of organism. For example, this information can be utilized in making an initial identification on a patient sample in a hospital laboratory. Second, some microorganisms can be  beneficial such as those bacteria that can be cultured from yogurt. Furthermore, these microorganisms can also be used to build back a healthy population of intestinal bacteria in patients who have recently been taking antibiotics. Answers to the LabPaq Questions 1) Questions A. Identifythe following parts of the microscope and describe the functionof each. a. Ocular- eyepiece transmits and magnifies the image form the objective lens to the eye. b.Body/tube-holds the eyepiece at proper distance from the objective lens and blocks light. c.Nosepiece- rotating mount that hold objective lens. d.Objective Lens- gathers light for the specimen. e.Mechanical Stage- holds the specimen. f.Apeture diaphragm control/disc- alters the amount of light that reaches the condenser. g.Lamp- produces the light. h.Coarse focus knob-brings objects into focal point of the objective lens. i.Fine focus knob- makes fine adjustments to focus the image. j.Arm-holds all of the optical parts at a distance and aligns them. k.Clips-hold the specimen still on the stage. l.Base- supports the weight of all the microscope parts. Define the following microscopy terms: Focus: positions the objective lens at the proper distance from the specimen. Resolution: Ability for the lens to show fine details of the object being observed. Contrast: The darkness of the back ground relative to the specimen. B. What is the purpose of immersion oil? To direct the light from the microscope directly to the slide and stop it from refracting. It creats a finer resolution and brightness. Exercise 2: Observing Bacteria Cultures in Yogurt Questions A. Describe your observations of the fresh yogurt slide. B. Were there observable differences between your fresh yogurt slide and the prepared yogurt slide? If so, explain. C. Describe the four main bacterial shapes. Cocci – oval or spherical shaped. Bacillus – are rod shaped. Spirillum – are thick, rigid spirals. Vibrio – are curved or a comma shaped rod. D. What are the common arrangements of bacteria? Diplo – oval shaped, found in pairs. Strepto – are cocci that arange into chains. Staphylo – are cocci that are arranged into irregular clusters, similar to grapes. E. Were you able to identify specific bacterial morphologies on either yogurt slide? If so, which types? Exercise 3: Preparing andObservingaBloodSlide Questions A. Describe the cells you were able to see in the blood smear. B. Are the cells you observed in your blood smear different than the bacterial cells you have observed? Why or why not?

Youtube Videos as Nursing Study Tools

The biggest con would be that It goes Into a lot of unneeded Information when considering my audience Is nursing students. There is a lot of Information that nurses don't necessarily need to know. Imperativeness. (2014, January 3). Oxygenation of the Respiratory System for Nursing [Video file]. Retrieved from http://move. Youth. Com/watch?

Martin Rexes, the user who uploaded the video, apparently sakes these videos, speaking about what he learned in nursing school that day along with tips on studying.For the nursing student this is great and helpful for studying. They video is short, easy to understand, and summarizes the oxygenation lecture for a nursing school class. The cons are that It Is rather boring, It may be difficult to rely on Information on a subject from an Inexperienced nursing student, and while It summarizes oxygenation very well, it doesn't go into very much depth. Sinking, S. (2014, January 3). U School of Nursing Oxygenation Song [Video file]. Retrieved from http://www. Youth. Mom/watch? FzHatR96cBxw I have a soft spot for these videos that use a song for teaching purposes.We know that every student learns In different ways so by presenting a video using a song to help remember important parts of oxygenation or any other topic is great. They cover important parts about oxygenation with a catchy tune which can help students learn or remember these parts better. It's a fun video so it is a sort of way to take a break while still learning. The cons are that it is really a very poorly made video as far as production value goes. At times it is difficult to hear the song and it is, obviously, a I felt that the first video, from abracadabra, was the best video considering my audience.Yes, it is lengthy, but it is so thorough and tells the viewer everything that they need to know about oxygenation. I felt that the speaker in the vid eo did a great job with visuals as he discussed the information in a clear and concise way. Chapter 41 – Fluid and Electrolytes Youth videos Monoclinic, M.

Retrieved from http://www. Youth. Com/watch? V=Japanned As far as content goes for this particular video it isn't the best choice because it only talks about a short topic pertaining to fluid and electrolytes. I chose this video though because of the creator of the video, Michael Liners. He creates videos for nursing students about everything that we need to know to be nurses. The pros are that Michael Liners clearly and easil y discusses topics that make it easy to understand, Mr..Liners specifically created these videos for nursing students, and it's a fun video, I thought that the use of humor and analogies were great. The cons are that, as I fluid and electrolytes. The production value of the video is pretty poor and it's difficult to hear the speaker at times. My favorite video was the near comprehensive one by Megan Monoclinic. The fact that is specifically made to help nursing students understand everything they can about fluid and electrolytes is reason enough to consider it the best of the three, but t is Just really well made and thorough in content.Youth videos as study tools I have found that Youth videos are great for study tools and knowledge generators. As nursing students there are so much material that we much digest and memorize at times. As I mentioned earlier, everyone learns in different styles and it seems that Youth has a video for people who have any of the many different learning styles. As supplemental material these Youth videos are best used. Most of the videos aren't meant to be used as a way to learn everything there is to know bout a certain topic, but to give a person a baseline on a topic of interest.I couldn't think of many cons to using Youth as a study tool. I believe that if something can help you than you should use it. If there is any argument against using Youth as a study tool it's that there isn't anyone to check information to see if it is correct. Anyone can upload a video about anything, spout nonsense and inaccurate information and no one would know. So, as supplemental material to what your teacher is telling you in class these videos can be beneficial, but not as a main source of knowledge.

Dissolve Definition in Chemistry

Dissolve Definition in Chemistry In chemistry, to dissolve is to cause a solute to pass into a solution. Dissolving is also called dissolution. Typically, this involves a solid going into a liquid phase, but dissolution can involve other transformations as well. For example, when alloys form, one solid dissolves into another to form a solid solution. Specific criteria must be met for a process to be considered dissolution. For liquids and gases, the substance that dissolves must be capable of forming non-covalent interactions with the solvent. For crystalline solids, the crystal structure needs to be broken up to release atoms, ions, or molecules. When ionic compounds dissolve, they separate into their component ions in the solvent. The term solubility refers to how readily a substance dissolves in a specific solvent. If dissolution is favored, the substance is said to be soluble in that solvent. In contrast, if very little solute dissolves, it is said to be insoluble. Keep in mind, a compound or molecule may be soluble in one solvent yet insoluble in another. For example, sodium chloride is soluble in water but not as soluble in organic solvents such as acetone or turpentine. Examples Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent. Dissolving salt in water is an example of dissolution of an ionic compound. The sodium chloride (salt) dissociates into sodium and chloride ions when it is mixed with water. Releasing the helium from a balloon into the atmosphere is also an example of dissolving. The helium gas dissolves into the larger volume of the air.

Antimalware and Antispam Technology Case Study Example | Topics and Well Written Essays - 1250 words

Antimalware and Antispam Technology - Case Study Example The decision proved costly as the software exhibited a persistent tendency to incorrectly identify Outlook files as malware and permanently delete them. Within two weeks it had deleted dozens of important emails. As no amount of configuring seemed to solve this problem, we made the transition to Symantec's Norton Internet Security. Since 2004, every computer and laptop in our company has been running Norton Internet Security. The software has, quite successfully, prevented users from logging onto a host of sites which we have identified as potentially threatening and from running peer to peer software. Indeed, the results of the ICT Department's periodic review of the application's logs indicate that Norton Internet Security has effectively protected us from a wide array of malware. Effective protection, however, does not mean immunity and therefore, we have implemented a second level of protection. Following a thorough investigation of anti-malware applications the ICT department decided to implement BINDER. A host-based detection system that can detect a wide class of malware on computers, including worms, spyware, and adware, with few false alarms, it operates through a simple algorithm which is based on inferring user intent. It detects new unknown malware on personal computers by identifying extrusions, malicious outbound network requests which the user did not intend. At the same time, and as the ICT Director informed me, we have also developed and implemented a large-scale honeyfarm system that ensures high-fidelity honeypot operation, efficiently discards the incessant Internet .background radiation that has only nuisance value when looking for new forms of activity, and devises and enforces an effective containment policy to ensure that the detected malware does not inflict external damage or skew internal analyses. Operating side-by-side, these two malware detection systems have, over the past fifteen months, effectively protected the company from malware attacks and infections. 3.1 Inferring User Intent I asked our ICT Director precisely how BINDER infers user-intent connections and, in response, he cited a very simple example. Let us assume that a user opens an Internet Explorer (IE) window, goes to a news web site, then leaves the window idle. In this example, new connections are generated in the following four cases: (1) When the user opens IE by double-clicking its icon on My Desktop in Windows, the shell process explorer.exe (PID=1664) of Windows receives the user input, and then starts the IE process. After the domain name of the default homepage is resolved, the IE process makes a connection to it to download the homepage. This connection of IE is triggered by the user input of its parent process of explorer.exe. (2) Case II: After the user clicks a bookmark of news.yahoo.com in the IE window, the domain name is resolved as xx.xxx.xx.xxx. Then the IE process makes a connection to it to download the HTML file. This connection is triggered by the user input of the same process. (3) Case III: After receiving the HTML file in 4 packets, IE goes to retrieve two image files from the websites in question. IE makes connections to them after the domain

Construction and organisation management. Tendering and estimating Essay

Construction and organisation management. Tendering and estimating - Essay Example But now the situation is getting better and the CSN also stated that the industry will have a growth rate of 1.4% each year from 2011-14. Under such a recession that the medium and small contractors must restrategize themselves, their policies and their operating zones. As it is seen that the north parts of UK have seen massive downturn, and whereas other parts such as wales and London have seen growth due to important events such as Olympics and etc. It is to be noted that there are about 614 contracting companies working in the south east England which is the highest no of companies that work in any other region of UK, on the other hand there are about 511 contracting companies that operated in the London region. This statistics clearly show the high level of saturation in the market and the stiff competition to get projects. This fact the bidding process of L & H significantly, as L & H should go for the project which it has been invited for and at the same time it should be consc ious of the fact that cost analysis of the project should be done vigorously and carefully as new location of project can open new markets for the company as well as cause loss to the company due to in experience in that region. The solution I suggest for the problem is that L & H must go for the bidding process with its full strength and if it is successful in getting the project it must involve and hire the workers and form a team which consists of the local people as well as L & H old loyal workers. Personally I believe that if L & H gets the new work at even a small profit it should go for it, as the main focus of the company should be getting projects and sustaining itself in recession. Then another fact that is to be noted that the growth rate of construction industry is about 1.4% but the growth rate of the south east England is just 0.8% which clearly shows that the growth in this region is less and companies need to move out of the region to sustain their own growth. Then L & H must also view which type of project is it bidding for, it is to be noted that there is huge growth in some sectors of construction industry and there is huge decay in the others. It is suggested that the L & H should be looking forward in creating its good will and name in the public sector as it is the only sector having significant funding at the moment. Whereas on the other hand private sector is not any longer investing much as it is in process to recover itself from the recession and has no confidence on the returns. It is to be noted that infrastructure sector of the construction industry is growing immensely that is it is growing at a rate of more than 6.7 % and majority of the projects coming up are of Infrastructure, contrary to this is the housing sector which is badly struck and experience a decay of 3.9 %. So when L & H must be bidding and going for projects in infrastructure sector. Concluding the discussion if L & H is to survive in these difficult times of reces sion and have to sustain its own growth it has to take a certain level of risk which is to expand its operational area and work in areas where there is both growth and lesser competition. On the other hand it has to emerge itself as a mainstream public sector contractor which mains interest is working in infrastructure and development. b) Morale has been low on several sites in one area, communication and quality of work has suffered. Discuss It has been proved

Hospitality Service Management Assignment Example | Topics and Well Written Essays - 1500 words

Hospitality Service Management - Assignment Example Innovation is the key focus to excel in this industry. Utilising service management for proper handling and delivery of services is the aspect which the services industry must set a priority in their areas of concern for promotion and company's growth - including industries in health care, caterers, manufacturers and suppliers, tourism and financial services. Organisations must set the difference between the idea of customer satisfaction and service of quality rendered to clients. Although sometimes considered ambiguous, a specific label is required that will detach these important entities with regards in providing services of which supposed as one. Both are correlated in terms of industrial needs but different. Customers may vary on every organisation to which they provide their products, be of services or goods, by some mechanism acceptable in the industry's marketplace. Of course, getting through the competition in the market is another endeavour which organisation needs focus. Customer satisfaction is a business term which is used to capture the idea of measuring how satisfied an enterprise's customers are with the organization's efforts in a marketplace (Wikipedia, 2006). Once customer's expectations are exceeded, the organisation will attain high levels of customer satisfaction and will create "customer delight." This implies that organisation must possess the ability to fulfil the consumers' needs through business, emotional and psychological aspects. The interaction between the service provider and the recipient, which are the customers, must not be in idle to properly measure the level of satisfaction. Proper attitude in dealing with varied customers should be considered; knowing their attitudes, feedbacks or commendations can contribute in determining the organisation's marketing strategies. Basically, organisations aim is to retain customers in patronising their services offered and the target of increasing the number of loyal customers and eventua lly increasing the organisation's revenues. Although customer satisfaction may vary from customer-to-customer, it is important to consider that physical and psychological characteristics which play a very important factor in measuring the degree where customers satisfy with the organisation's services. Comparatively speaking, the customer's expectation can be evaluated with the customer's experience prior relevant to the services the organisation delivers. Organisation must take into account that satisfaction is not quantitatively measured since it is more of a psychological aspect; it is more of the qualitative. And, service of quality will be now measured. Commonly, customers define 'quality' as they are met by their perception and experience. This is the degree or level of customer's satisfaction with the services or products an organisation offers dependently to the environment and the kind of service given. It is difficult to conform to the expectations of the customers needs with the level they require with regards to efficiency, quality, flexibility, and dependability to the services delivered. To achieve this, Total Quality Management (TQM) is applied. TQM is management philosophy committed to a focus on continuous improvements of product and services with the involvement of the entire workforce. This principle is a long-term process to sustain business excellence and the comprehensively and continuously involvement of all organisation functions. Through this method,

College - Is it Worth it Essay Example | Topics and Well Written Essays - 500 words

College - Is it Worth it - Essay Example Shipley is very educated with a doctorate degree, which explains his urge to make people have a wide understanding of the essence of college education in life. This argumentative essay explores college education from both its positive and negative sides (Goldman, 2011). Shipley does not impose a decision on the readers of his article, but advises them to use their time wisely while in college. He says that college can build people or leave them with extreme resentment for the rest of their lives. Moreover, he argues that many people proceed to college just to fulfill the societal expectations. He proceeds to say that though sometimes one may feel wasted after college, she/he may focus on socialization, time management and decision making skills gained while in college (Rampell, 2011). Looking at the whole idea of college education logically, Shipley can be credited for his presentation. He not only looks at education bit of it but also incorporates the social aspect of college experience. Life does not only revolve around education, in fact, it requires one to have very good social skills. College experience gives people a chance to know how to control their lives. Rampell (2011) argues that for an individual to be successful in life, he/she needs both the technical knowledge related to his/her career, as well as decision making and managerial skills. This is mainly gained in college, however to only those who manage this experience wisely. I truly support Shipley’s arguments because they seem very objective. Rampell (2011) concurs that it is true that many students who regret their experience in college are likely those who never set their priorities right while in college. They end up completing their college education without anything much to show of it. As much as you can join college and pursue a field not of your interest, you can always learn to make something good out of it.

A Reflection on Children Full of Life Movie Review

A Reflection on Children Full of Life - Movie Review Example On my part, the message of this short video virtually demolishes certain ideas regarding the aims and methods of teaching primary education level students. For a long time, I have always held on to the belief that teachers are supposed to project an impression of infallibility when it comes to teaching subjects to students. Aside from this, I have also thought that teachers should be strict disciplinarians, unwavering in their commitment to impose rules on the students and even, unbending, when it comes to meting disciplinary actions. However, I could not believe it when the teacher, Mr. Kanamori, actually allows his students to express their opposition to his views and, ultimately, changing his previous stance of punishing Yuto. There are actually two things that struck me while watching the clip; first is the students’ compassion towards their classmate, and second is the teacher’s teaching style and appreciation of the students’ independent and opposing views. I think that the two are actually related to each other. In the first place, a very rigid atmosphere in the classroom established by the teacher would make it impossible for children at such young age and to learn how to assert their ideas even if these are not in concurrence to those of the teacher.

Poets childhood Essay Example for Free

Poets childhood Essay In Mrs. Tilschers Class by Carol Ann Duffy deals with one central theme. The theme of growing up is the main idea within the poem and is repeatedly imprinted throughout the poets childhood. This theme leads on to the more abstract idea of the child already maturing into a great poet. Her minds eye is unbounded as she transforms her classroom into a place of riches and resides in her own world of imagination. Written improbably through the 2nd person viewpoint, the poem expresses these ideas personally to the reader, hence allowing us to empathise with the poet. The poet is able to recall several aspects of her primary school days, and is consequently able to paint a picture of her memories from the viewpoint of a young child. The writer not only conveys an inviting warm atmosphere of a 1960s classroom, but also unveils a liberal outlook to her childhood. A colourful classroom with numerous displays is made known to the reader: The classroom glowed like a sweet shop. The classroom is made into a place of riches with this visual simile, used to radiate wonders of the childs mind. The word glowed in this line is a metaphor all on its own. The metaphor allows the reader to visualise the sweetshop gleaming due to the light refracting through the glass jars and translucent sweets. The poet can also bring to mind the teachers blackboard, as she informs the reader of how the chalky Pyramids rubbed into dust. In a literal sense the chalky lines on the board became chalk dust. The poet imagines this to be great pyramids and monuments being eroded inevitably by time. The bell signifying the end of playtime is remembered as: The laugh of a bell, swung by a running child. This auditory image incorporates the personification of the bell, to compare its sound to an incessant laugh of a child. The bells laugh is a transferred epithet from the child, as the children too were laughing, overwhelmed with joy as they returned to their classroom for another dose of Mrs. Tilscher. The poets joy is so intense and infectious, that it reaches out and transforms the whole scene. Such is the magnitude of the poets emotion. The laugh is also a visual image, as the reader can see a smile as the arc of the bell, and the clapper hitting the sides of it is almost comparable to a tongue. However other images such as a skittle of milk are more informative and suggest the time setting of the poem. The poet also remembers a music room next door to her classroom, though only by means of a xylophones nonsense heard. This auditory image describes the noise of the xylophone next door and this is further expanded by the use of the single metaphoric word nonsense which implies the vague unclear noise heard and the fact that the primary school children are producing uncoordinated music. The enthralling books were not to be forgotten to the poet, as they had made her a slave to them continually, due to their alluring influence. All the images used to recall aspects of the poets primary school principally focus on an emotional and sensual level. The primary school classroom may have been a place memorable to the poet through various images, but the definitive piece of the poets 1960s school life was Mrs. Tilscher. Mrs. Tilschers voice is not even forgotten, as the poet reminisces her voice as she chanted the scenery. Mrs. Tilschers chanting brings about connotations of music in her voice and melodic speech. It also brings about a sense of religion, as she is made comparable to a pastor in a church chanting a sermon, enlightening and entrancing us all. Mrs. Tilscher is portrayed as a compassionate teacher: Mrs. Tilscher loved you and shows kindness and care. The terms around the lines focused on Mrs. Tilscher also have an implication on how she is illustrated to the reader. Words with intense connotations such as glowed, sweet, sugar and coloured have associations with moods of joy, brilliance, love and bliss which all elaborate on Mrs. Tilschers image. The teacher is also illustrated to be appreciative: Some mornings you found shed left a good gold star by your name. Although it seems that the poet finds aspects of the classroom just as unforgettable as Mrs. Tilscher, the poet essentially portrays the classrooms essence to be the work of Mrs. Tilscher, through her tone of voice. Choices of words or diction such as could have connotations of possibility. When put into context and further developed on, the implications go as far as unconstrained and limitless possibility. The teacher opens up a whole world of possibility, and it is because of this the poet remembers so much about her classroom, a boundless environment. It is because of Mrs. Tilscher that the poets classroom surroundings were made to be so memorable. The poets tone of voice and language varies throughout the poem, and strong distinction is made between the first two stanzas and the last two stanzas. The language in the first two stanzas is exceptionally exuberant, more child-like in an emotional sense and the imagery is much more pleasant to envisage, filled with colour, vibrancy and liveliness: Sugar paper. Coloured shapes. Each individual phrase builds up an atmosphere full of warmth. However the last two stanzas are less joyous in their atmosphere, as the poet makes her transition to a state of being overwhelmed by hormones. The word connotations also vary greatly in these two stanzas, bringing suggestions of anger, accusation and dismay: You kicked him, but stared at your parents, appalled. The stanzas are also bleaker in description and imagery is uninviting: The air tasted of electricity. The poets feelings in stanza four are troubled, after being introduced to topic of how she was born: A tangible alarm made you always untidy, hot, fractious under the heavy, sexy sky. Such sentences furthermore use more mature and sophisticated language, which coincide with her growth as the language also develops. Therefore the poets outlook and tone of voice changes as she becomes much more interested in growing up than going to primary and learning in a high-spirited vibrant classroom. The reader of the poem is invited to personally explore the main ideas within the poem. This personal involvement of the reader seems appropriate, as the main theme conveyed, the journey of growing up, is your own personal exclusive journey. This personal involvement is due to the narration of the poem from the second-person viewpoint. This is shown through the excessive use of the second-person pronoun You. By using this narration style, the experience of the young poet is made universal and common. We can all be subjected to her experiences of growing up from the second-person narrative perspective. Although the reader finds it easy enough to face the poets experiences, Mrs. Tilscher feels that she should have no influence in the young childs journey of growing up, and that such a journey should proceed at the persons own pace. When the child asks the teacher about how she was born, Mrs. Tilscher smiled, then turned away. Mrs. Tilscher may have believed that the poet would learn in her own time, but the poet nevertheless encourages the reader to enter her journey. The poem illustrates two worlds in which the poet resided during her childhood days. The reader is able to capture not only the essence of the classroom, but also the limitless realm of the childs imagination. Both these worlds exist alongside each other agreeably as the classroom is made into a creative place itself due to the influence of Mrs.Tilscher. The foremost apparent world presented by Carol Ann Duffy is the classroom. The classroom conveys images of riches, sweets, colour and joy. However beyond this, the classroom is seen to be a sanctuary. The classroom was a safe house against the world of murder and crime outside, as suggested by the mention of Brady and Hindley of the 1960s. The real world begins to force an entry into the childs reverie as she slowly begins to become conscious of the world outside. This is the first occasion in which the poet shows signs of growing up, which enforces the main theme of the poem. The girl learns that the real world isnt to be trusted. The classroom however is portrayed as a world of its own, not troubled by the likes of such horrific murderers. The fear fades away in the classroom, and along with this so does the little hint of adulthood. She postpones her transition into adulthood for the meantime, as the poet shows us by using a child-like image after the allusion: Brady and Hindley faded, like the faint uneasy smudge of a mistake. This second component to the sentence indirectly illustrates the use of a pencil, and the occurrence of silly mistakes. It is because of this implication that the poet moves back into the state of childhood. The growth of the poet is exemplified in this classroom world, and therefore this world is very significant to the theme. Conversely, on a more abstract plane, the poem portrays another world within the childs mind. A whole world of imagination and vision. The poet expresses that she could travel up the Blue Nile with your finger tracing the route. The poet is tracing her finger down the Nile, and is in her imaginative world of Egypt. On the other hand, in reality the teacher is demonstrating sketch maps on the board. The word within the poem, which establishes both worlds within and without, is a metaphor on its own. The word travel is the single metaphor, which suggests that the poet is on a journey within her mind, when actually she is stationary within her school seat. The poet also conveys the main theme in this imaginative world, as the child not only travels with her finger and during her daydream, but she furthermore travels through her journey of growing up. The child is beginning to grow into a great poet, and this is shown through various lines within the poem. A very strong contributor to this idea of the girl growing into a great poet is an example of synaesthesia: The scent of a pencil, slowly carefully shaven. This image appeals to all of the senses at once, and incorporates kinetic, olfactory, visual and tactile aspects. This line shows how the poet carefully shaved her pencil, just in the same way she carefully crafts sentences. This is extended even further by the link made between the writing tool and the writing process. The child poet is even able to link this image full of senses to the main theme of growing up. The act of the girl carefully shaving the pencil, symbolises how she is shaving or peeling off her childhood as she makes the transition into adulthood. The poet gradually conveys to the reader that there are two states of growth within the poem, and that the girl is maturing both into adolescence and into a mind of an exceptional poet. The last stanza of the poem focuses the atmosphere and the attitude of the poet into an uninviting overcast, but also centers in on the theme. It illustrates the feverish month of July, oppressed by the summer and heat. Alongside this are the hormones of the child, felt almost within the air. These hormones amplify the effect of the afflicting heat. The air also tasted of electricity, which conveys the anticipation of summer thunderstorms due to the heavy air. However electricity also relates with the hormones to suggest that the child will spark at random times and also that the growth of the child is full of charge, energy and excitement. Further along, the use of the phrase a tangible alarm portrays an almost touchable fear within the air. This fear made the girl fractious under the sexy sky. This expresses to the reader that the girl had many sudden outbursts of anger due to her hormones. These hormones influence her thoughts and are the causes behind the poet using the term sexy to describe the sky. The last line of the poem communicates how this adolescent phase is like a thunderstorm. The thunderstorm represents her feelings of puberty, as she feels as though the whole world is coming down on her, just as in a thunderstorm. The lightning of a thunderstorm also links to the connotations of the electricity. The lightning of the thunderstorm could symbolize the mood swings awaiting the child. The lightning also illustrates the fact that there is an unsettlement within the child, as if an electric current was continually running through her. The rain of a thunderstorm conveys the downpour of gloom upon the child throughout the hard times to come. On an overall view the experience of puberty and growing up is just a phase and in time will pass. Soon the child will be entirely in adulthood. Likewise the thunderstorm is just an unpleasant phase in the sequence of weather and in time shall pass. Before long the sun will overpower such a ghastly occurrence of weather. Overall, In Mrs.Tilschers Class by Carol Ann Duffy is a poem which allows the reader to personally identify themselves with the poet. The poem is contrastive between the stanzas and thus the poet is able to isolate the main idea. Two worlds are created expressing the wonders of the classroom, but also illustrating the unconstrained world of the girls imagination. Through these two worlds we see signs of the girl growing into a great poet. However the most essential idea of the poem is the theme of growing up and maturing. It is a journey through adolescence: You ran through the gates, impatient to be grown.

Fragment Allocation In Distributed Database Design

Fragment Allocation In Distributed Database Design A database that consists of two or more data files located at different sites on a computer network. Because the database is distributed, different users can access it without interfering with one another. However, the DBMS must periodically synchronize the scattered databases to make sure that they all have consistent data, or in other words we can say that a distributed database is a database that is under the control of a central database management system (DBMS) in which storage devices are not all attached to a common CPU. It may be stored in multiple computers located in the same physical location, or may be dispersed over a network of interconnected computers. Collections of data (e.g. in a database) can be distributed across multiple physical locations. A distributed database can reside on network servers on the Internet, on corporate intranets or extranets, or on other company networks. Replication and distribution of databases improve database performance at end-user worksites. To ensure that the distributive databases are up to date and current, there are two processes: Replication. Duplication. Replication involves using specialized software that looks for changes in the distributive database. Once the changes have been identified, the replication process makes all the databases look the same. The replication process can be very complex and time consuming depending on the size and number of the distributive databases. This process can also require a lot of time and computer resources. Duplication on the other hand is not as complicated. It basically identifies one database as a master and then duplicates that database. The duplication process is normally done at a set time after hours. This is to ensure that each distributed location has the same data. In the duplication process, changes to the master database only are allowed. This is to ensure that local data will not be overwritten. Both of the processes can keep the data current in all distributive locations. Besides distributed database replication and fragmentation, there are many other distributed database design technologies. For example, local autonomy, synchronous and asynchronous distributed database technologies. These technologies implementation can and does depend on the needs of the business and the sensitivity/confidentiality of the data to be stored in the database, and hence the price the business is willing to spend on ensuring data security, consistency and integrity. Basic architecture A database User accesses the distributed database through: Local applications Applications which do not require data from other sites. Global applications Applications which do require data from other sites. A distributed database does not share main memory or disks. Main Features and Benefits of a Distributed System A common misconception among people when discussing distributed systems is that it is just another name for a network of computers. However, this overlooks an important distinction. A distributed system is built on top of a network and tries to hide the existence of multiple autonomous computers. It appears as a single entity providing the user with whatever services are required. A network is a medium for interconnecting entities (such as computers and devices) enabling the exchange of messages based on well-known protocols between these entities, which are explicitly addressable (using an IP address, for example). There are various types of distributed systems, such as Clusters [3], Grids [4], P2P (Peer-to-Peer) networks, distributed storage systems and so on. A cluster is a dedicated group of interconnected computers that appears as a single super-computer, generally used in high performance scientific engineering and business applications. A grid is a type of distributed system that enables coordinated sharing and aggregation of distributed, autonomous, heterogeneous resources based on usersà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ QoS (Quality of Service) requirements. Grids are commonly used to support applications emerging in the areas of e-Science and e-Business, which commonly involve geographically distributed communities of people who engage in collaborative activities to solve large scale problems and require sharing of various resources such as computers, data, applications and scientific instruments. P2P networks are decentralized distributed systems, which enable applications such as fil e-sharing, instant messaging, online multiuser gaming and content distribution over public networks. Distributed storage systems such as NFS (Network File System) provide users with a unified view of data stored on different file systems and computers which may be on the same or different networks. The main features of a distributed system include: Functional Separation: Based on the functionality/services provided, capability and purpose of each entity in the system. Inherent distribution: Entities such as information, people, and systems are inherently distributed. For example, different information is created and maintained by different people. This information could be generated, stored, analyzed and used by different systems or applications which may or may not be aware of the existence of the other entities in the system. Reliability: Long term data preservation and backup (replication) at different locations. Scalability: Addition of more resources to increase performance or availability. Economy: Sharing of resources by many entities to help reduce the cost of ownership. As a consequence of these features, the various entities in a distributed system can operate concurrently and possibly autonomously. Tasks are carried out independently and actions are co-ordinate at well-defined stages by exchanging messages. Also, entities are heterogeneous, and failures are independent. Generally, there is no single process, or entity, that has the knowledge of the entire state of the system. Various kinds of distributed systems operate today, each aimed at solving different kinds of problems. The challenges faced in building a distributed system vary depending on the requirements of the system. In general, however, most systems will need to handle the following issues: Heterogeneity: Various entities in the system must be able to interoperate with one another, despite differences in hardware architectures, operating systems, communication protocols, programming languages, software interfaces, security models, and data formats. Transparency: The entire system should appear as a single unit and the complexity and interactions between the components should be typically hidden from the end user. Fault tolerance and failure management: Failure of one or more components should not bring down the entire system, and should be isolated. Scalability: The system should work efficiently with increasing number of users and addition of a resource should enhance the performance of the system. Concurrency: Shared access to resources should be made possible. Openness and Extensibility: Interfaces should be cleanly separated and publicly available to enable easy extensions to existing components and add new components. Migration and load balancing: Allow the movement of tasks within a system without affecting the operation of users or applications, and distribute load among available resources for improving performance. Security: Access to resources should be secured to ensure only known users are able to perform allowed operations. Several software companies and research institutions have developed distributed computing technologies that support some or all of the features described above. Fragment Allocation in Distributed Database Design On a Wide Area Network (WAN), fragment allocation is a major issue in distributed database design since it concerns the overall performance of distributed database systems. Here we propose a simple and comprehensive model that reflects transaction behavior in distributed databases. Based on the model and transaction information, two Heuristic algorithms are developed to find a near-optimal allocation such that the total communication cost is minimized as much as possible. The results show that the fragment allocation found by the algorithms is close to being an optimal one. Some experiments were also conducted to verify that the cost formulas can truly reflect the communication cost in the real world. INTRODUCTION: Distributed database design involves the following interrelated issues: (1) How a global relation should be fragmented, (2) How many copies of a fragment should be replicated? (3) How fragments should be allocated to the sites of the communication network, (4) What the necessary information for fragmentation and allocation is. These issues complicate distributed database design. Even if each issue is considered individually, it is still an intractable problem. To simplify the overall problem, we address the fragment allocation issue only, assuming that all global relations have already been fragmented. Thus, the problem investigated here is determining the replicated number of each fragment and then finding a near-optimal allocation of all fragments, including The replicated ones, in a Wild Area Network (WAN) such that the total communication cost is minimized. For a read request issued by a transaction, it may be simple just to load the target fragment at the issuing site, or it may be a little complicated to load the target fragment from a remote site. A write request could be most complicated since a write propagation should be executed to maintain consistency among all the fragment copies if multiple fragment copies are spread throughout the network. The frequency of each request issued at the sites must also be considered in the allocation model. Since the behaviors of different transactions maybe result in different optimal fragment allocations, cost formulas should be derived to minimize the transaction cost according to the transaction information. Alchemi: An example distributed system In a typical corporate or academic environment there are many resources which are generally under-utilized for long periods of time. A à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"resourceà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚  in this context means any entity that could be used to fulfill any user requirement; this includes compute power (CPU), data storage, applications, and services. An enterprise grid is a distributed system that dynamically aggregates and co-ordinates various resources within an organization and improves their utilization such that there is an overall increase in productivity for the users and processes. These benefits ultimately result in huge cost savings for the business, since they will not need to purchase expensive equipment for the purpose of running their high performance applications. The desirable features of an enterprise grid system are: Enabling efficient and optimal resource usage. Sharing of inter-organizational resources. Secure authentication and authorization of users. Security of stored data and programs. Secure communication. Centralized / semi-centralized control. Auditing. Enforcement of Quality of Service (QoS) and Service Level Agreements (SLA). Interoperability of different grids (and hence: the basis on open-standards). Support for transactional processes. Alchemi is an Enterprise Grid computing framework developed by researchers at the GRIDS Lab, in the Computer Science and Software Engineering Department at the University of Melbourne, Australia. It allows the user to aggregate the computing power of networked machines into a virtual supercomputer and develop applications to run on the Grid with no additional investment and no discernible impact on users. The main features offered by the Alchemi framework are: Virtualization of compute resources across the LAN / Internet. Ease of deployment and management. Object-oriented Grid thread programming model for grid application development. File-based Grid job model for grid-enabling legacy applications. Web services interface for interoperability with other grid middleware. Open-source .Net based, simple installation using Windows installers. Alchemi Grids follow the master-slave architecture, with the additional capability of Connecting multiple masters in a hierarchical or peer-to-peer fashion to provide Scalability of the system. An Alchemi grid has three types of components namely the Manager, the Executor, and the User Application itself. The Manager node is the master / controller whose main function is to service the user Requests for workload distribution. It receives a user request, authenticates the user, and distributes the workload across the various Executors that are connected to it. The Executor node is the one which actually performs the computation. Alchemi uses role based Security to authenticate users and authorize execution. A simple grid is created by Installing Executors on each machine that is to be part of the grid and linking them to a Central Manager Component. Advantages of distributed databases Management of distributed data with different levels of transparency. Increase reliability and availability. Easier expansion. Reflects organizational structure database fragments are located in the departments they relate to. Local autonomy a department can control the data about them (as they are the ones familiar with it.) Protection of valuable data if there were ever a catastrophic event such as a fire, all of the data would not be in one place, but distributed in multiple locations. Improved performance data is located near the site of greatest demand, and the database systems themselves are parallelized, allowing load on the databases to be balanced among servers. (A high load on one module of the database wont affect other modules of the database in a distributed database.) Economics it costs less to create a network of smaller computers with the power of a single large computer. Modularity systems can be modified, added and removed from the distributed database without affecting other modules (systems). Reliable transactions Due to replication of database. Hardware, Operating System, Network, Fragmentation, DBMS, Replication and Location Independence. Continuous operation. Distributed Query processing. Distributed Transaction management. Disadvantages of distributed databases Complexity extra work must be done by the DBAs to ensure that the distributed nature of the system is transparent. Extra work must also be done to maintain multiple disparate systems, instead of one big one. Extra database design work must also be done to account for the disconnected nature of the database for example, joins become prohibitively expensive when performed across multiple systems. Economics increased complexity and a more extensive infrastructure means extra labour costs. Security remote database fragments must be secured, and they are not centralized so the remote sites must be secured as well. The infrastructure must also be secured (e.g., by encrypting the network links between remote sites). Difficult to maintain integrity à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ in a distributed database, enforcing integrity over a network may require too much of the networks resources to be feasible. Inexperience distributed databases are difficult to work with, and as a young field there is not much readily available experience on proper practice. Lack of standards there are no tools or methodologies yet to help users convert a centralized DBMS into a distributed DBMS. Database design more complex besides of the normal difficulties, the design of a distributed database has to consider fragmentation of data, allocation of fragments to specific sites and data replication. Additional software is required. Operating System should support distributed environment. Concurrency control: it is a major issue. It is solved by locking and time stamping.

The Purpose of Disguise in Twelfth Night Essay -- Twelfth Night essays

Theme of Disguise in Twelfth Night The notion of disguise is very important theme within Twelfth Night.   From my point of view I feel that the crux of the play is primarily based on this concept.   Indeed "there's something in it that is deceivable" summarizes this point precisely.   Disguise runs like a thread through the play from start to end and holds it all together just as tightly as thread would fabric.   Yet, paradoxically as the plot progresses there are many problems, deceptions and illusions, which provide a comment on human behavior and creating the needed escape of comedy. The place of women within the theatre is well known, that being that they had no place within the stage.   Women's parts were played by young men in Shakespeare's day, so that the audience would have found sophisticated in Viola's part:   a boy dressing up as a woman who, in the play disguises herself as a man. The first example of the use of disguise in the Twelfth Night is Viola's disguise as Cesario.   As aforementioned this notion is central to the plot.   I think it is clearly evident that the fluctuation in attitude to the dual role and the situations and tribulations imposed upon the character Viola/Cesario, ends up creating a better understanding of both sexes and thus, allows Viola to have a better understanding of Orsino.   Viola learns whil... ...

The Adverse Effects of Advertising on Women Essay -- Cause Effect Imag

The Adverse Effects of Advertising on Women Stacey was tall, blonde, tan, and slender. However beauty was not her only attribute. In addition to being voted Homecoming queen our senior year of high school, she was both a straight-A student and the President of our class. She was a strong leader who enjoyed having fun like any other girl her age. Yet in between the jokes and fun that most friends have, she was always talking about going to the gym or counting calories. Despite my constant reassurances that she was beautiful the way she was, she never felt adequate. In Stacey’s eyes nothing less than perfect would do. She believed that there was an ideal image that she had to obtain in order to be considered attractive. After trying diet after diet and joining several health programs, Stacey’s waistline finally began to get smaller; the compliments only made her want to lose more. As time went on, it was clear that her health was beginning to suffer. Her eyes had a more sunken appearance, and her once toned body looked unnaturally bony. Gradually, Stacey was starving herself. An average American will see hundreds, perhaps even thousands, of advertisements on a day-to-day basis, which attempt to manipulate impressionable minds into a new way of living. Advertisements may be good sources of information about new or revised products, but at what cost? The barrage of slender woman with perfect skin and hair emits the idea that there is such a thing as a perfect woman. The actresses, musicians, and models in these ads create a warped sense of beauty, which in turn affects women’s self-perception. Yet this goddess-like image is exactly what advertisers rely upon in order to continue their revenue. D... ...sion ads may not be real, but the affects that they have on women are. From discouragement and sadness to depression and diseases, forms of false advertising oftentimes have a negative impact on the morale of the American people, including Stacey, whose battle with anorexia continues. The saddest part of the whole scenario is that things could be different if advertisers were to put a little of their greed aside in lieu of the unique charisma of people by putting models of all shapes, sizes, and varieties in their ads. After all, who defines the normal woman anyway? Works Cited Greg Apodaca â€Å"Greg’s Digital Archive† Greg Apodaca’s Website. September 22, 2003.

Heuristics and Biased Essay

Daniel Kahneman along side of Amos Tversky revolutionized research on human judgment. They conceptualized the idea of the â€Å"heuristics and biases† program – that judgment under uncertainty Often rests on a limited number of simplifying heuristics rather than extensive algorithmic processing. Gigerenzer criticized Kehneman and Tverskys research stating that humans are capable of processing more complex algorithms than what Kehneman and Tversky were giving homage to. Thus a debate of what the cognitive capacity is and the deviations between normative models and actual human reasoning has been called into question by casting doubt on the appropriateness of the normative models used to evaluate performance, a form of the â€Å"reject-the-norm† strategy. It has been noted the Panglossians, exclusively used the reject the-norm-application strategy to eliminate gaps between descriptive models of performance and normative models. When this type of critique is employed, the normative model that is suggested as a substitute for the one traditionally used in the heuristics and biases literature is one that coincides perfectly with the descriptive model of the subjects’ performance, thus preserving a view of human reasoning and rationale as ideal. Gigerenzer urged that the cognitively capacity is in fact more than this. Gigerenzer urged that there is sufficient evidence for the existence of two types of processing in Human reasoning, decision making, and social cognition. One type fast, automatic, effortless, and non-conscious, the other slow, controlled, effortful, and conscious, which may deliver different and sometimes conflicting results. More recently, some cognitive psychologists have proposed ambitious theories of cognitive architecture, according to which humans possess two distinct reasoning systems, almost two Minds, known as System 1 and System 2. A composite characterization of the two systems runs as follows. System 1thinking, one relies heavily on a number of heuristics (cognitive maneuvers), key situational characteristics, readily associated ideas, and vivid memories to arrive quickly and confidently at a judgment. System 1: thinking is particularly helpful in familiar situations when time is short and immediate action is required. System 2 is more recent, and its processes are slow, controlled, effortful, conscious, serial, shaped by culture and formal tuition, demanding of working Memory and related to general intelligence. It is reasoning based on what we have learned through careful analysis, evaluation, explanation, and elf-correction. This is the system which values intellectual honesty, analytically anticipating what happens next, maturity of judgment, fair-mindedness, elimination of biases, and truth-seeking In addition, it is often claimed that the two systems employ different procedures and serve different goals, with System 1 being highly contextualized, associative, heuristic, and directed to goals that serve the reproductive interests of our genes, and System 2 being decontextualized, rule-governed, analytic, and serving our goals as individuals. This is a very strong hypothesis, and theorists are already recognizing that it requires substantial qualification and complication. Gigerenzer is not denying that normatives appropriate for simple case judgments exist, but rather expostulates that the existence and the nature of such normative have been imperiously assumed by the heuristics and biases literature. Gigerenzer argues that some of the biases identified by Kahneman and Tversky are unstable, in the sense that for example in some cases their magnitude can be considerably reduced by asking questions in terms of frequencies rather than in terms of probabilities. Second, on a methodological level, Gigerenzer argues that, because Kahneman and Tversky’s heuristics are formulated by means of vague, theoretical terms like representativeness, the appeal to these heuristics as generators of biases has limited explanatory power; Gigerenzer advocates instead an increasing emphasis on investigating the cognitive processes that underlie judgment under uncertainty. Third, on a normative level, Gigerenzer argues that it may be inappropriate to characterize some of the biases identified by Kahneman and Tversky as â€Å"errors† or â€Å"fallacies†. Gigerenzer’s reason for objecting to the use of the term â€Å"bias† Gigerenzer argues that Kahneman and Tversky may be comparing the performance of the participants in their experiments with incorrect normatives. Many critics have insisted that in fact it is Kahneman & Tversky, not their subjects, who have failed to grasp the logic of the problem. Or that if a â€Å"fallacy† is involved; it is probably more attributable to the researchers than to the subjects. When ordinary people reject the answers given by normative theories, they may do so out of ignorance and lack of expertise, or they may be signaling the fact that the normative theory is inadequate.
