Kidney infection, cystitis caused by Escherichia Coli (E-Coli) Research Paper - 1

Kidney contamination, cystitis brought about by Escherichia Coli (E-Coli) - Research Paper Example These contaminations are normally brought about by Escherichia coli (E. coli). This microorganisms is available in gut and digestive system. The contamination happens when this microscopic organisms goes into urethra during intercourse or cleaning from back to front after discharge. Going into urethra and arriving at bladder brings about cystitis. At the point when this microorganisms arrives at kidneys, it causes kidney contamination for example Pyelonephritis. The kidney contamination can happen in one kidney or both simultaneously. The measurements have indicated that proportion of ladies experiencing these contaminations is higher than men since it is simpler for microorganisms to move to urethra from encompassing skin. Also, the length of urethra is lesser in ladies which make it simpler for microbes to arrive at bladder. The kidney contamination because of E. Coli, can likewise occur without cystitis which as a rule happens when the kidney is blocked or the patient has other wellbeing issue for example kidney stone, diabetes, low insusceptibility and so forth (Gupta et al., 2011; Madappa et al., 2011). Kidney disease can bring about further difficulties, for example, boil, kidney irritation and blood harming. In youthful male patients, back urethral valves are the principle destinations for straightforward urinary tract contamination though more established men with prostatic hypertrophy are increasingly inclined to it (Mayfield-Blak, 2012). Potential strategies for assessment may incorporate urinalysis and pee culture where initial one will help in looking at blood parts alongside synthetic concoctions like nitrites in the pee test, the later one is expected to inspect the nature and substance of microbes for remedy of right anti-infection. Cytoscopy and imaging tests can likewise be utilized (Gupta et al., 2011). Treatment mostly incorporates admission of anti-microbials by mouth or direct addition into urethra.

10 High Impact Foods to Boost Your Energy and Productivity

10 High Impact Foods to Boost Your Energy and Productivity There are several factors that affect one’s energy and productivity. One’s environment (e.g. the people around them, or even the circumstances), culture, educational background, character and attitude.If we are motivated enough, we feel more energized to perform assigned tasks. If asked, you can probably name a dozen ways for you to get a boost in your energy levels and, without a doubt, food would be one of them.But did you know that what you eat also affects your productivity? Making the connection between the food that you eat and your energy may be easy. However, most people find it hard understanding how it may affect productivity. © Shutterstock | Jacek Chabraszewski, Filk, Nattika, Bildagentur Zoonar GmbH, Dionisvera, Losangela, JeniFoto, Alexander Moss, Africa Studio, M. Unal OzmenIn this article, we will explore 1) the connection between food, energy, and productivity, 2) 10 foods that will boost your energy and productivity, and 3) some additional tips.THE CONNECTION BETWEEN FOOD AND ENERGY PRODUCTIVITYThe relationship between food and energy is pretty much established for most of us: in order to have energy, one must eat. Try skipping meals in the morning, and you are likely to feel completely drained of energy a few short hours into the day.To better understand the connection, let us take a look at the physiological side of things. Food contains calories, which are essentially units of energy that our bodies then utilize, much like a fuel, in the performance of all bodily functions. The very act of breathing is fueled by these units of energy, so you can just imagine the amount of energy required in or der to perform more strenuous activities, such as doing a household chore or playing your favorite sport.Essentially, the more active you are, the more energy that your body will need. This means that you will also need more food.It is in foods where you will find macronutrients, such as carbohydrates, fat, and protein â€" the three main players in the generation of energy in the body. Carbohydrates and protein, by themselves, already provide calories or units of energy. Fats, on the other hand, still has to undergo some processes before they can provide energy that can be used by the body. In the end, however, it is considered to be another great source of energy.According to the United States Department of Agriculture (USDA), for optimum energy, the recommended calories to be obtained from carbohydrates on a daily basis is 45% to 65%. Fats and proteins, on the other hand, should provide around 20% to 35% and 10% to 15%, respectively.Food contains specific nutrients that help us fe el more energized. For example, women aged 20 to 49 have been found to be more prone to fatigue attributed to iron deficiency. The solution is to consume more foods that are iron-rich. Now where does productivity come in?It is like a chain reaction: the more energized you are, the better a performer you will be in any assigned task. You will be able to work longer hours, and your concentration and focus will be much more improved, as compared to when you haven’t eaten anything.The nutrients found in many foods also protect you from various diseases and health problems, so you are healthier, which means you are more capable of carrying out simple to advanced tasks and functions.But wait, it’s not just food and eating per se that will have a positive effect on productivity. According to the World Health Organization, “adequate nutrition can raise productivity levels by 20% on average”. Take note that they specifically cited “adequate nutrition”, which means you also have t o take into consideration the quantity and the quality of the food that you eat, not just the mere fact that you are eating food.10 FOODS FOR BOOSTING ENERGY AND PRODUCTIVITYThe general consensus when it comes to choosing food to eat for energy is to combine a fruit or a vegetable, whole grain, lean protein, plant-based fat, and any herb or spice. As long as these 5 ingredients are present in one meal, you can expect to get the maximum amount of energy, which you will then use to be more productive at work, at home, or in school.Technically, all foods supply energy. It is just a matter of some foods being better suppliers than others. With so many types of foods out there, the big question is what are the best choices that you should include in your “energy and productivity” diet? We have narrowed the list down to the ten best energy- and productivity-boosting foods.#1 CHICKEN BREASTWe have mentioned the three macronutrients required for energy, and they include proteins. Chicke n is one of the best and most abundant sources of protein that you can find, and the fact that it is tasty definitely doesn’t hurt.To get the most out of the protein provided by chicken breast, avoid deep-frying or frying it. Leaving it overnight in a marinade or preparing it with lots of sauces and other ingredients will diminish its protein content. Try to keep it simple by grilling it. It’s tastier and healthier that way. #2 EGGSEggs are usually a favorite breakfast fare, but they can actually be eaten at any time throughout the day. This is because eggs are rich in protein (they came from chicken, which we have already established as protein-rich, so that’s a given) as well as other nutrients such as healthy fats, potassium, and fiber, boosting your energy and providing long-lasting fullness.In fact, if you eat an egg in the morning, you tend to feel fuller longer, and more energized to carry out your tasks for the day.Consume the whole egg. Others may say you should just eat the white part, completely avoiding the egg yolk. #3 FISH SHRIMPSeafood has always been a great source of various vital nutrients, which is why you see it recommended in almost every type of diet. Seafood, particularly fish and shrimp, is rich in omega-3 fatty acids, which have a close correlation with one’s mood and memory.People who have optimal to high levels of omega-3 seldom experience depression, and you rarely see them display pessimistic outlooks. They also tend to be more calm and objective, instead of acting on impulse often to the point of recklessness.What types of fish should you consider including in your diet? Salmon (particularly wild salmon), sardines and mackerel, often come highly recommended.Watch Jamie Oliver cooking some really healthy fish recipes. Yummy! #4 GREEK YOGURTDairy is generally good for the health, but there have been issues lately with some types of dairy causing more harm than good. Greek yogurt is one of the exceptions, as it has been prov en to contain a lot of proteins.Why not just stick to normal yogurt? There is nothing wrong with normal yogurt, since they also contain protein. However, since we are talking about the best options, Greek yogurt is the way to go. After all, they contain about two times the protein that you will find in normal yogurt.When choosing Greek yogurt, steer clear of those with high sugar content. Go for plain, unflavored and unsweetened Greek yogurt. To add flavor, you can simply add a little bit of fruit or your favorite jam.Another way to enjoy Greek yogurt is to blend it with your favorite fruit for a smoothie. This will give you a healthy dose of protein (for energy) and fiber (to make you feel fuller for a long time).[slideshare id=40787528doc=theemerginggreekyogurtmarket-141027153724-conversion-gate01w=640h=330]#5 SEEDS AND ALMONDSLooking for an energy snack? Then try some seeds and nuts, such as almonds. Some seeds, such as hemp seeds, can even be added in salad dressings and smoothi es. Chia seeds are also often added to cereals. Eat them raw or toast them, if you prefer. These seeds are great protein providers, and also excellent sources of fiber, good fats, calcium, iron, magnesium, zinc, and omega-3 fatty acids.Nuts such as almonds are not only good for the prevention of various heart diseases. They are also effective in hunger management. If you find yourself easily feeling hungry at any time of the day, almonds are great for easing these hunger pangs.Take note that not all nuts are recommended, since some of them may have high sugar or fat content. Almonds are considered to be an excellent alternative since they are much healthier.If plain almonds are too boring for you, you can try almond variations, such as almond milk and almond butter. They will also give you the same amount of energy that regular almonds provide. #6 OATS AND QUINOAWe have to be specific about this, since there are more than a few oatmeal varieties available today. Look for steel-cut o ats or oatmeal. They are also referred to as coarse oatmeal or pinhead oats, depending on which part of the world you’re from. They are basically whole oats which have been roughly chopped into several pieces. The oat groats are essentially unprocessed, unlike your usual rolled oats or instant oatmeal.When you look over the shelves at the stores and supermarkets, you may feel overwhelmed with the wide variety of choices of oatmeal. Some are dubbed as “quick-cooking”, while there are also the instant ones, which you can prepare just by adding hot water.Eat the oats raw or toast them a bit. Again, when serving oatmeal, avoid putting too much sugars. If flavor is what you want, healthier alternatives are jams or preserves, or a side serving of your favorite fruit.The same is true for Quinoa, or the “Mother Grain”. Quinoa is 20% protein, and also rich in vitamin B, which actively works in converting carbohydrates into energy that will be used by the body. Usually, quinoa is a great addition to baked goods, soups, stews, and cereals. #7 KALEKale may just be the most popular and highly recommended leafy green vegetable lately, and with good reason, too. Kale supplies the body with iron, Vitamin A, Vitamin C (which aids in better iron absorption) and Vitamin C (which improves blood clotting and blood flow in general).The great thing about kale is how flexible it is when it comes to serving it. You can eat it raw with your salads, or use it as toppings on your burgers or pizzas. You can even mix it with your soup. A popular way of preparing and consuming kale lately, though, is blending it in with smoothies. Some even turn them into kale chips, but you have to be careful that they were not prepared through deep-frying. #8 BLUEBERRIES AND GOJI BERRIESIf you are looking for good antioxidants, berries are one of the first things on the list. Blueberries, in particular, are a perennial favorite, ranking among the “superfruits”, along with apples and tomatoes . Did you know that blueberries can also help improve memory and brain power? This means you can be more confident in tackling tasks that involve using your brain and memory better!Goji berries, on the other hand, are increasingly becoming popular as additions to baked goods as well as in juices, teas and smoothies. They are even added to soups and cereal mixes. Goji berries contain 18 amino acids, easily providing you lots of protein, and vitamin B2 and iron. Improved blood flow is sure to improve the flow of energy, which ensures you remain in top condition. #9 WATERMELONBlood flow is associated with energy levels, and watermelon is a great fruit for relaxing the blood vessels and improving blood circulation. That is thanks to the amino acid called L-citrulline, which is found in abundance in watermelon.If you have often wondered why watermelon is highly recommended after a workout or a strenuous activity, it is because watermelon also helps soothe sore muscles. Eat the fruit on i ts own, add it to a salad, or blend it into a smoothie. You have a lot of options available.#10 DARK OR RAW CHOCOLATESweet-lovers rejoice! You can indulge in your love for sweets and not worry that it would cramp your style when working or studying. If you need a quick pick-me-up, your usual go-to may be some candy or a chocolate bar, because the sugar content will perk you right up. However, we suggest you pick up dark chocolate, or even raw chocolate, instead of your regular sweets.Dark chocolate contains a lot of antioxidants; in fact, cacao is considered as one of the best sources of antioxidants, as well as nutrients such as magnesium, iron, manganese and chromium. Most importantly, cacao contains anandamide, which is instrumental in improving one’s mood and keeps energy going.If you can’t get your hands on raw chocolate or cacao, choose pre-packaged dark chocolate with the least amount of sugar, and with a lot of cacao. Usually, dark chocolate has a cacao content of at lea st 70%, so that’s a good starting point. OTHER TIPS TO BOOST YOUR ENERGY AND PRODUCTIVITYEating the abovementioned foods is not going to be enough if you truly hope to give your energy a boost and improve your overall productivity. The food will do its part, but you, too, will have to do your part. Here are some additional suggestions that you should consider in order to make the most out of your “energy and productivity” diet.Do not skip meals. Have a regular meal or eating schedule, and stick to it. You will notice that, if you skip even a single meal, you tend to tire easily and even have mood swings. When you finally get to eat, you end up eating too much or eating the wrong types of food. Do not forget that food is your body’s fuel. If you do not “gas up” regularly, then you should not expect your engine to be in good running condition whenever you need it to. Heed what the elders tell you: have a full breakfast, so you can function better for the rest of the day.Be conscious of what you eat. Awareness is the first step. You should know what you are eating, and what benefits you can get from them. This will also help you in planning your next meals. Do you have a particularly challenging week at work ahead? Then you should prepare yourself properly, and one way to do that is to eat right, and eat the right foods that will provide the energy that you need.Do not eat something because it is cheap. While it is true that eating healthy often translates to “eating expensive”, you are presented with a trade-off scenario. Will you eat a cheap but unhealthy meal that will not be able to sustain you for the rest of the afternoon, or will you eat a healthy and energizing meal, even if it is slightly more costly? In the long run, you will end up spending more, because you will look for a snack to fill you up where your previous cheap meal was not able to.Avoid processed foods and foods with artificial ingredients. As much as possible, limit your inta ke of these foods, because they can actually drain energy instead of supplying them. A good example is caffeine. While some would say that caffeine can perk you up, it actually gives “artificial energy”, because it zaps you right out afterwards. Keep things in moderation. If you have to consume caffeine, alcohol and other foods with refined sugars, do so in moderation. What about energy drinks? These mostly contain sugar, which provide temporary bursts of energy. After a short while, you will feel tired, so you’d grab another bottle of the energy drink. It’s going to be an endless cycle that you could have avoided if you chose the right energy-boosting foods.Maintain balance in your diet. If you are going to eat carbs, make sure you have other nutrients thrown in. It’s all about balance, to make sure that you do not fall short on one area and have too much of another.

Three Varieties of Knowledge- a Critque Free Essays

Donald Davidson- Three Varieties of Knowledge Submitted By: Nathan Copeland- 500349268 Submitted to: Prof. Checkland PHL550 April 15, 2013 In Donald Davidsons Three Varieties of Knowledge, he sets out to more or less prove that â€Å"A community of minds is the basis of knowledge; it provides the measure of all things. † (Davidson, 218). We will write a custom essay sample on Three Varieties of Knowledge- a Critque or any similar topic only for you Order Now This is done by first categorizing knowledge into three distinct categories. There is knowledge of ones own mind, knowledge of another’s mind, and knowledge of the shared physical world around us. He argues that no one could exist without the others. According to Davidson, knowledge of ones own mind differs from the other two types of knowledge in the sense that one knows the contents of their own mind without any study or evidence in most cases. On the other hand, the minds of others and the physical world may only be interpreted through the senses, at least initially. He also notes that certain aspects of our physical world can be interpreted almost instantaneously, our example being distinguishing colours, while many aspects of another’s mind contents are done through physical observation of actions and words, which we then reconcile with our own knowledge to make inferences. This makes the latter two types of knowledge open to a degree of uncertainty that is rarely experienced in matters of your own mind. He also acknowledges the asymmetry that is apparent between coming about knowledge of our own minds and knowledge of other minds. They are both minds, yet we come to understand our own in a very unique way. He criticizes the solution that the actions and behavior or others is sufficient for inferring certain mental states to others, but those same actions and behaviours carried out by our selves are irrelevant when we attempt to describe ourselves. An issue being- If both types of knowledge come about so differently, how can we believe that others mental states are comparable to our own. He sets out to paint a picture that includes all three types of knowledge, and shows how they are related in hopes of solving these issues. Davidson claims that â€Å"what we could not do is get along without a way of expressing, and thus communicating, our thoughts about the natural world† (Davidson, pg. 208). He also proposes that in order for a creature to have a belief, they must also posses the idea of objective truths. He then draws on Wittgenstien to say that â€Å"the source of the concept of objective truth is interpersonal communication† (Davidson, pg. 209). This is based on the assumption that thought cannot exist without language. Davidson argues that without the distinction between objective truth and what one thinks to be the case, there is no thought at all, and since there cannot be objective truth without the confirmation on the correct use of words through communicating, there cannot be thought without communicating, in his example language. It is argued that in order for communication to work, the speaker and interpreter must share an understanding of what is meant by what is being said. Davidson then uses an example of how one would go about learning a new language to illustrate how we come about having an understanding of the words we use. In this case, we assign words and sentences we know in our native tongue to the utterances and actions made by a foreign speaker. With trial and error we come to understand what is meant by these utterances and how they relate to ‘reality’. This process of connecting ones own thoughts with the thoughts of another through some aspect of the external world is regarded by Davidson as triangulation. â€Å"it takes two points of view to give a location to the cause of a thought, and thus define its content† (Davidson, pg. 213). He believes this to be the only way that one can know another’s mind or the external world, making the two mutually dependent. He points out that there is the limitation of perception at play here, with no way to look in from outside the standard to see if its write, but we may consult a third and forth party and so on to lessen the chance of an error being made. Davidson, pg. 217) Davidson then goes on to say that â€Å"knowledge of the propositional contents of our own minds is not possible without the other forms of knowledge, since there is no propositional thought without communication† (Davidson, pg. 213). Furthermore, knowledge of others cannot be inferred unless we have kn owledge of ourselves, as the process of coming to know another’s mind is done by matching evidence from others behaviour to our knowledge of our own, thus showing that knowledge of our own minds and others is also mutually dependent. He acknowledges that there are a great deal of possible ways that we could assign our native language to the language and behavior of another to come about an understanding. He relates this to the measurement of weight in the sense that no matter what system you use for measurement; kilograms, pounds ounces, etc. , the invariable factor, in this case the actual weight of the object, is the fact of the matter, not the arbitrary units of measure. His point is that there will likely always be indeterminacy in our translations, but we will often get the general idea. He also believes that there are no strict laws that connect mental states with physical ones, stating that such laws can exist â€Å"only when concepts connected by the laws are based on criteria of the same sort† (Davidson, pg. 215). This all leads to the fact that we will never be able to agree on how sentences and thoughts should be structured to describe other sentences or thoughts, as the very process of discussing how we would do this is ultimately done with the very thoughts were discussing, leaving it perpetually open to interpretation. As such â€Å"A community of minds is the basis of knowledge; it is the measure of all things. It makes no sense to question the adequacy of this measure, or to seek a more ultimate standard. † (Davidson, pg. 218). Analysis I agree with the general idea of what Davidson is saying, with a few exceptions. I would agree that ‘advanced’ knowledge can only come about with the all three types of evidence, but I also believe that basic knowledge can be acquired by just a person and the observable world. Suppose I live in a world with no other living creatures. I have no formal language. If I walk across a bed of sharp rocks, my nervous system will say â€Å"ouch†, and it wont take long to figure out that sharp rocks hurt my feet. I am aware of this with no need to confirm with another. I am also in contention with the idea that â€Å"language is essential to thought† (Davidson, pg. 209). My dog ‘thinks’ its going for a walk every time I put my boots on. I suppose that may be considered language, or some may argue that my dogs actions have no thought, but it seems to me that to make such a claim demands more evidence. I also had an issue with the claim that â€Å"enough in the framework and fabric of our beliefs must be true to give content to the rest† (Davidson, pg. 214). Although I agree that ‘enough’ of our beliefs are true, I don’t see this as a necessary condition. What if everything we think is wrong, or we’re a brain in a vat. The claim is overly definitive for my liking. Going back to my ‘only creature’ idea, I find the statement â€Å"there is no propositional thought without communication† (Davidson, pg. 213). Perhaps on this lonely planet I have a rock, which I am in love with. I may possess the thought, as primitive as it may be, that I love this rock. We don’t communicate, but the thought remains. This may be argued as a feeling, not a thought, but I’m not sure I know the difference. Finally, I have another idea that is in opposition to Davidsons claims, although I’m not sure if I believe it myself. He seems to think there are three distinct categories of knowledge, with knowledge of ones self coming mostly from inside, and knowledge of the world and others minds coming indirectly. My idea is this; all of the thoughts, behaviors, desires etc. , of any living creature is merely a manifestation of very complex processes happening in our brains. Our brains are chemicals and axons and neurons and much more that we are not 100% about. I’m proposing that theoretically, if we can observe the brain all the way down to each and every atom, we could see how your brain looks for any given idea, memory, feeling, and document the physical state relating to each and every instance. The only difference between the three states is how we go about knowing them, and with this theory we could even come to know our own minds without having to think internally about how we feel, but by merely observing our brains. Tying this back to my ‘alone in the world’ scenario, if I had the capability to observe my own brains inner workings while feeling the mental manifestations of such neurological reactions, I could correlate the pictures with feelings the ame way we correlate others words with objects in the world. If I became well enough versed at this, I could then look at the brain of someone else whom I’ve never seen, and come to know their mind as well. This theory is in contradiction with Davidson’s statement that there are no strict laws that connect mental states to physical ones, but even he acknowledges that this topic â€Å"has understandably been found inconclusive by critics† (Davidson, pg. 216), myself included.

Arab Israeli Wars Essay Example For Students

Arab Israeli Wars Essay Sincethe United Nations partition of PALESTINE in 1947 andthe establishment of the modern state of ISRAEL in 1948,there have been four major Arab-Israeli wars (1947-49,1956, 1967, and 1973) and numerous intermittent battles. Although Egypt and Israel signed a peace treaty in 1979,hostility between Israel and the rest of its Arab neighbors,complicated by the demands of Palestinian Arabs, continuedinto the 1980s. THE FIRST PALESTINE WAR (1947-49)The first war began as a civil conflict between PalestinianJews and Arabs following the United Nationsrecommendation of Nov. 29, 1947, to partition Palestine,then still under British mandate, into an Arab state and aJewish state. Fighting quickly spread as Arab guerrillasattacked Jewish settlements and communication links toprevent implementation of the UN plan. Jewish forcesprevented seizure of most settlements, but Arab guerrillas,supported by the Transjordanian Arab Legion under thecommand of British officers, besieged Jerusalem. By April,Haganah, the principal Jewish military group, seized theoffensive, scoring victories against the Arab Liberation Armyin northern Palestine, Jaffa, and Jerusalem. British militaryforces withdrew to Haifa; although officially neu tral, somecommanders assisted one side or the other. After the Britishhad departed and the state of Israel had been established onMay 15, 1948, under the premiership of DavidBEN-GURION, the Palestine Arab forces and foreignvolunteers were joined by regular armies of Transjordan(now the kingdom of JORDAN), IRAQ, LEBANON, andSYRIA, with token support from SAUDI ARABIA. Effortsby the UN to halt the fighting were unsuccessful until June11, when a 4-week truce was declared. When the Arabstates refused to renew the truce, ten more days of fightingerupted. In that time Israel greatly extended the area underits control and broke the siege of Jerusalem. Fighting on asmaller scale continued during the second UN trucebeginning in mid-July, and Israel acquired more territory,especially in Galilee and the Negev. By January 1949, whenthe last battles ended, Israel had extended its frontiers byabout 5,000 sq km (1,930 sq mi) beyond the 15,500 sq km(4,983 sq mi) allocated to the Jewish state in the UNpartition resolution. It had also secured its independence. During 1949, armistice agreements were signed under UNauspices between Israel and Egypt, Jordan, Syria, andLebanon. The armistice frontiers were unofficial boundariesuntil 1967. SUEZ-SINAI WAR (1956) Border conflictsbetween Israel and the Arabs continued despite provisions inthe 1949 armistice agreements for peace negotiations. Hundreds of thousands of Palestinian Arabs who had leftIsraeli-held territory during the first war concentrated inrefugee camps along Israels frontiers and became a majorsource of friction when they infiltrated back to their homes orattacked Israeli border settlements. A major tension pointwas the Egyptian-controlled GAZA STRIP, which was usedby Arab guerrillas for raids into southern Israel. Egyptsblockade of Israeli shipping in the Suez Canal and Gulf ofAqaba intensified the hostilities. These escalating tensionsconverged with the SUEZ CRISIS caused by thenationalization of the Suez Canal by Egyptian presidentGamal NASSER. Great Britain and France strenuouslyobjected to Nassers policies, and a joint military campaignwas planned against Egypt with the understanding that Israelwould take the initiative by seizing the Sinai Peninsula. Thewar began on Oct. 29, 1956, after an announcement that thearmies of Egypt, Syria, and Jordan were to be integratedunder the Egyptian commander in chi ef. Israels OperationKadesh, commanded by Moshe DAYAN, lasted less than aweek; its forces reached the eastern bank of the Suez Canalin about 100 hours, seizing the Gaza Strip and nearly all theSinai Peninsula. The Sinai operations were supplemented byan Anglo-French invasion of Egypt on November 5, givingthe allies control of the northern sector of the Suez Canal. .u6ad8974edc1a281fbfa68e3aa5d3fdb6 , .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .postImageUrl , .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .centered-text-area { min-height: 80px; position: relative; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 , .u6ad8974edc1a281fbfa68e3aa5d3fdb6:hover , .u6ad8974edc1a281fbfa68e3aa5d3fdb6:visited , .u6ad8974edc1a281fbfa68e3aa5d3fdb6:active { border:0!important; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .clearfix:after { content: ""; display: table; clear: both; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6:active , .u6ad8974edc1a281fbfa68e3aa5d3fdb6:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .centered-text-area { width: 100%; position: relative ; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6:hover .ctaButton { background-color: #34495E!important; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6 .u6ad8974edc1a281fbfa68e3aa5d3fdb6-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6ad8974edc1a281fbfa68e3aa5d3fdb6:after { content: ""; display: block; clear: both; } READ: Kant: The Universal Law Formation Of The Categorical Imperative EssayThe war was halted by a UN General Assembly resolutioncalling for an immediate ceasefire and withdrawal of alloccupying forces from Egyptian territory.

The Ipremier Company Denial of Serivice Attack. Case Analysis Essay Example Essay Example

The Ipremier Company: Denial of Serivice Attack. Case Analysis Essay Example Paper The Ipremier Company: Denial of Serivice Attack. Case Analysis Essay Introduction The iPremier Compant (A): Denial of Service Attack Summary of the case: iPremier, a Seattle based company, was founded in 1996 by two students from Swathmore College. iPremier had become one of a few success web-based commerce, selling luxury, rare, and vintage goods over the Internet. Most of iPremier’s goods sell between fifty and a few hundred dollars, and the customer buys the products online with his or her credit card. iPremier’s competitive advantage is their flexible return policies which allows the customer to thoroughly check out the product and make a decision to keep the product or return it. The majority of iPremier customers are high end, and credit limits are not a problem. iPremier had contracted with Qdata, an Internet hosting business. Qdata provided iPremier with most of their computer equipment and connectivity to the Internet. Qdata was not an industry leader and was selected because it was located close to iPremier’s company headquarters and had been serving iPremier throughout the course of its new and developing business. Qdata did provide basic floor space, power, connectivity, environmental control, and physical security, and offered some high-level management services such as monitoring of web sites for customers and Internet security services such as firewall protection. On January 12, 2007, iPremier Web servers were brought to a standstill. A denial-of-service (DoS) attack had occurred. Hackers launched the attack on iPremier. Luckily for iPremier, this was only a denial-of service attack, possibly launched by a script-kiddie, or even a competitor trying to disrupt service. The Ipremier Company: Denial of Serivice Attack. Case Analysis Essay Body Paragraphs The attack could have been a lot worse. iPremier’s customers pay for their purchases with credit cards, and they keep a data base containing all credit card information on their customers. The credit card database is. However, it leaves them vulnerable to an attack by hackers. If a hacker had obtained total access to their system customer credit card numbers could have been in jeopardy. As the events unfold, iPremier managers discover problems with their plans for responding to crises and struggle to understand and control the situation. 1. How well did this company perform during the attack? The company did not perform as well as they should have been able to. There were multiple areas where problems arose, such as the technical architecture of the IT system, relying only on the 3rd party, Qdata, to monitor their IT infrastructure, keeping out of date manuals, and not maintaining their emergency procedures. However, some people trying to fix the attack did an adequate job con sidering the problems the company had. Joanne and Leon Ledbetter did everything in their power to restore the website and protect the customer data, which even included running red lights. Leon was so new that he didn’t know exactly what to do. Training for an emergency would have proven useful. The CIO, Bob Turley, knew of the emergency protocol and out of date manuals, but never did anything to alleviate these problems. This put the company in a significant disadvantage, and created a bigger problem than what was necessary. Faced with this problem, Turley was able to facilitate direction for the company as best as he could, which ended with the security breach stopping. Even after the attack, when the company did not know whether the customer information, which included credit card information, the company had no intention to announce the security breach to the public. This can be detrimental to the company if customers became impacted because of this issue. This is probabl y an unethical response to this event, and further shows how bad the company performed during this crisis. 2. What should they have done differently, before or during the event? One of their main problems was relying solely on Qdata to monitor their IT infrastructure. It sounds like Qdata was not keeping up to date with their investments in technology and adequate personnel. When Joanne was at Qdata, she made it sound as if the staff was uneducated and only allowed her limited access to resolve the situation. Their Website monitoring system and Internet security services did little to nothing to help resolve the situation. Another problem was iPremier neglecting to update their facilities and equipment because they wanted to focus more on expanding the company. This is a risky move because as the company grows the IT infrastructure needs to row to keep up with the greater risks a failure could cause. iPremier was not prepared for an attack; they could not even find their binder full of procedures in case of an emergency such as this one. They also had turned off their ability to log detailed information in case of an attack and Joanne believed that their firewall had not been set up properly. For this reason, they have no idea for why the attack had stopped. In some instances it may have appeared that they had panicked a little too much. They almost notified the police of the incident. They would have been a very hasty and unnecessary move. As far as I know, the police would have not been able to do anything to help the situation and at the same time the press would have access to the story. This would have hurt iPremier’s public relations and upset their executives and BOD. Their panic may also have caused an accident. Joanne was driving fast and running red lights. Again, if she got into an accident and the press got hold of why the accident occurred, there would have been a negative press release about the company. 3. What should they do in the after math of the event? Premier learned the hard way with this web’s attack that they needed to find a more effective outsourcing client. iPremier needs to realize the importance of security, especially in the e-commerce world where there is unlimited access through the Internet to valuable customer information. Security needs to be the top priority of any e-commercial company. They should make some changes to effectively solve their security problem. First of all, their existing contract with Qdata needs to be renegotiated. This will allow employees at iPremier to act as consultants for Qdata and help them upgrade their existing system. The consulting time will be an added cost, however it is far less expensive to consult rather than hiring another outsourcing client. Second of all, iPremier need to separate its web server from its critical system; this will help to eliminate access to important information by a hacker. No system is totally safe from an attack but the separation of systems will help to deter amateur hackers. Beside, iPremier needs to develop a plan of attack if they undergo a DoS again. By doing so, they can have a strategy to implement before, during, and after a denial-of-service. If their plan is effective the system then down time ill be decreased, and vital information will be secure again in a timely manner. Also when an attack occurs iPremier needs to have an expert to call to effectively walk top-level executives through the process of getting their system up and running. Finally iPremier’s current firewall needs to be updated with the addition security for example filter or sniffer, to successfully inhibit information packets that will initiate a DoS attack. 4. What, if anything, should they say to customers, investors, and the public about what has happened? iPremier’s made had no plan to announce the attack to customers. This may be a costly mistake. Because iPremier does not know the extent of the attack, or what was targeted, they do not know the extent of the risk to their customer. Officials of the company feel that making the attack public could risk their reputation from a public relations standpoint. However, not informing customers of the attack could be more costly. iPremier must quickly determine how they are going to approach this problem from an IT standpoint: will they hire another firm to research or will they work with Qdata to investigate the event? Next, iPremier should make a public announcement concerning the potential risk of compromised customer credit cards. Premier should also announce that their plan to remedy this problem and inform customers of how they will keep customer information safe in the future. Finally, iPremier should make a statement to reflect that they made every attempt to notify the public immediately after the attack to prevent any potential fraud to occur on customer credit cards. A similar event occurred with major retailer, TJ Maxx, several years a go. TJ Maxx did not discover the information leak for several months, and did not inform the public for some time after that. Not only did this create a public relations nightmare for TJ Maxx, there were also legal ramifications to their decisions. iPremier is correct in assuming they may lose customers in this process. However, the alternative approach, to remain silent, could prove more detrimental. Many customers will appreciate the honesty and the opportunity to close compromised credit cards immediately. On the other hand, if iPremier takes no action, and customer cards are compromised, they will face strong customer dissatisfaction and potential legal ramifications as well.

Role and Duties of the Governor General of Canada

Role and Duties of the Governor General of Canada The Queen or sovereign is the head of state in Canada. The Governor General of Canada represents the sovereign, and most of the powers and authority of the sovereign have been delegated to the Governor General. The role of the Canadian Governor General is mostly symbolic and ceremonial. The head of government in Canada is the Prime Minister, an elected political leader. Appointment of the Governor General The Canadian Governor General is selected by the Prime Minister of Canada, although the formal appointment is made by the Queen. The term of office of the Governor General is usually five years, but it is sometimes extended up to seven years. There is a tradition of alternating between anglophone and francophone Governors-General in Canada. Official Duties of the Governor General of Canada The official duties of the Governor General of Canada include: giving Royal Assent to bills passed in the Canadian House of Commons and Senatereading the Speech from the Throne which outlines the Canadian federal government agenda for a new session of Parliamentexecuting orders-in-council or cabinet decisionsappointing superior court judges, on the advice of ​the  cabinetsummoning, closing and dissolving Parliament, on the advice of the Prime Ministerinviting the leader of the party with the most support in the House of Commons to form the government.

Business Law - Essay Example This is selected because it contains very relevant explanations and outlines of how directors and shareholders are expected to relate towards the collective success of their companies. Several UK case laws are also going to be analysed in such a way that by the end of the discussions, Mary and Joseph would clearly identify areas of legal liability in the conduct of their directors and areas where no legal liabilities exist. Directors’ Duty Duty owed to the company and not individual shareholders First, it is important for Mary and Joseph to realise that prior to CA 2006, the directors owe their duty to the company as a body and not to individual shareholders of the company. However, it has been explained earlier that the company is only an artificial person, who must be represented by natural people. Mary and Joseph could therefore direct their actions in such ways that they are either seen as individual shareholders fighting for their interest in the company or as members of the company as a body1. ... Similarly, in Percival v Wright (1902), it was held that the director of the directors in some instances owe fiduciary duties to individual shareholders of the company. By further implication, how a petitioner positions him or herself in cases against the adjudication of the duties of directos is very important in determining what the outcome of the petition would be3. Mary and Joseph will therefore be advised to position their selves as constitute members of the company rather than as interested parties in the acquisition because of the directors’ duty is owed to the company and not to individual shareholders4. Power to issue shares Further advice given to Mary and Joseph would bother on the power that the directors of the company have to issue shares. It would be noted that s 171 CA 2006, which touches on the duty of directors to act within powers clearly outlines the powers given to the directors to exercise powers for the purposes for which they are conferred5. As part of the powers, given by most companies to their directors also, there is the power for the issuance of shares where directors have the right to issue shares that they deem as acts profitable ventures for the company6. In effect, the argument of Mary and Joseph cannot be against the mere issuance of shares in the acquisition process of the subsidiary firm. The acquisition of the subsidiary company through the issuance of shares could easily be justified by the directors through their power to issue shares if the purpose for the formation of the subsidiary company had finished serving its roles7. In Hogg v Cramphorn Ltd (1967), it was held that the directors of the company could not be charged for

The author states that mobile communication is the technology that has the greatest effect on the development of society and can be a major step towards industrialization in developing countries. He points out various implications of mobiles in the developing countries: The applications within mobile banking overcome the challenges posed by large geographic distances and infrastructure deficiencies for local business people and enhance safe transfer of funds. This reduces the risks involved in handling large sums of cash. Applications in the areas of education and information are also beneficial in third world countries. Mobiles also improve relations where family members and friends in the city and rural areas communicate and exchange information thereby overcoming the â€Å"major social problem†. He also notes that mobile phones create improved conditions for companies, which in turn creates better economic and social conditions thus raising living standards. One limitation that the author identifies is that the services and applications offered in third world countries are low-tech as this is what all parties ranging from operators to individuals in rural areas would afford. The author identifies a number of recommendations in the paper. He notes that mobile applications could be invaluable in helping health professionals and care providers get vital information, for instance, on HIV/AIDS and malaria to people living in isolated areas while access to obituary information via a mobile phone could make life easier. He also points out that provision of mobile phones to people in poor regions could significantly hasten development and that offering voice and sms services is the best way to raise living standards in Tanzania, an

Epidemiology Of Cholera John Snow Health Essay

Epidemiology Of Cholera John Snow Health Essay It has been over a century and a half when John Snow undertook the study of the Cholera epidemic of 1854 in London. His work, which was published in the 1855 book On the Mode of Communication of Cholera, is considered a milestone in epidemiology. The observations by Snow of the water-born transmission of cholera and the handle of the Broad Street pump was a work of genius that continues to inspire epidemiologists. Appearing before the local body of government on September 7, 1854, John Snow argued that the source of the outbreak of a cholera epidemic was water from a communal water pump. His investigation identified the pump at Broad Street near its intersection with Cambridge Street as the source of contaminated water. Cholera which is an acute, diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae, causes significant morbidity and mortality in many developing countries. This paper examines the cholera epidemics (and pandemics) in recent history i ncluding the outbreak of 1854 in London and the role played by John Snow which had laid the foundations for the modern principles of epidemiology. Introduction It has been over a century and a half when John Snow undertook the study of the Cholera epidemic of 1854 in London. His work, which was published in the 1855 book, On the Mode of Communication of Cholera is considered a milestone in epidemiology. The observation by Snow of the water-born transmission of cholera, and the handle of the Broad Street pump was a work of genius that continues to inspire epidemiologists. Appearing before the local body of government on September 7, 1854, John Snow, an anesthetist in London, argued that the source of the outbreak of a cholera epidemic was water from a communal water pump. Working with the data reproduced in table 1 (Bingham et al., 2004), Snow identified the pump at Broad Street near its intersection with Cambridge Street as the source of contaminated water. What followed is best told in his own words: I had an interview with the Board of Guardians of St. Jamess parish on the evening of Thursday, 7th September, and represented the above circ umstances to them. In consequence of what I said, the handle of the pump was removed on the following day (Snow, 1855). Each year, outbreaks of cholera to cause death estimated at 120,000 worldwide, with the vast majority occurring in children (WHO, 1995). Epidemiology of cholera is characterized by several key principles including (i) Cases tend to be concentrated in specific location and occur during a specific season (ii) the highest infection rates in children of 1-5 years in areas where infection is endemic (iii) antibiotic resistance patterns often change from year to year, (iv) pathogen strain often exhibit clonal diversity, and (v) prevention measures against the disease include sanitation, hygiene and immunity improvement. Cholera has been ranked as one of the emerging and reemerging infections (Satcher, 1995) facing many developing countries. Several recent events highlight the importance of epidemiological disease include the 1991recurrence of cholera in Latin America (Levine, 1991) ( Ries et al., 1992); the 1994 outbreak of cholera which took place in a Rwandan refugee camp in Goma, Zaire, which resulted in approximately 70,000 cases and 12,000 deaths in (Siddique, 1995), and the outbreak of V. cholerae O139 in the India subcontinent from 1992 to 1993, possibly marked the start of the eighth cholera pandemic (Ramamurthy et al., 1993)(Swerdlow et al., 1993). Pathogenesis and transmission of Cholera Vibrio Cholerae are comma-shaped, gram-negative bacteria that have been the cause of several great long-lasting epidemics and pandemics of diarrheal disease. Many of these pandemics began in the Ganges Valley of India and Bangladesh, which is never free from cholera. Although there are 140 serotypes of V. cholera, until recently only 1 stereotype was associated with several diarrhea. Beginning in 1992, a new V.cholerae stereotype (0139, also known as Bengal) has been associated with sever, watery diarrhea (Faruque et al., 1998) The vibrios never invade the epithelium but instead remain within the lumen and secrete an enterotoxin, which is encoded by a virulence phage. Flagellar proteins involved in motility and attachment are necessary for efficient bacterial colonization, as has been described for Campylobacter. The vibrio hemagglutinin, which is a metalloprotease, is important for detachment of Vibrio from epithelial cells. The secretory diarrhea characteristic of the disease is caused by release of cholera toxin. Cholera toxin is composed of five binding peptides B and a catalytic peptide A (McKenzie et al., 1984). The B peptide, serving as a landing pad, bind to carbohydrates on GM1 ganglioside on the surface of epithelial cells of the small intestine, enabling calveolar-mediated endosomal entry of toxin subunit A into the cell (Laloi et al. 1996). Reverse transport of the subunit A from endosome into the cell cytoplasm is followed by cleavage of the disulfide bond linking the two fragments of peptide A (A1 and A2). Catalytic peptide A1 is generated, leading to the following sequence (Dertzbaugh et al., 1993): A1 interacts with 20-kD cytosolic proteins called ADP-ribosylation factors (ARF). The ARF-A1 complex catalyzes ADP-ribosylation of a 49-kD G-protein (called GsÃŽÂ ±) (Randazzo et al., 2000). Binding of NAD and GTP generates an activated GsÃŽÂ ±, which in turn binds to and stimulates adenylate cyclase. ADP-ribosylated GsÃŽÂ ± is permanently in an active GTP-bound state, resulting in persistent activation of adenylate cyclase. The activated adenylate cyclase generates high levels of intracellular cAMP from ATP. Cyclic AMP stimulates secretion of chlorides and bicarbonate, with associated sodium and water secretion. Chloride and sodium reabsorption is also inhibited. The reabsorptive function of the colon is overwhelmed, and liters of dilute rice water diarrhea containing flecks of mucus-up to 14 L/day, equivalent to the circulating blood volume, causing dehydration and electrolyte imbalances. Because overall absorption in the gut remains intact, oral formula can replace the massive sodium, chloride, bicarbonate, and fluid losses and reduce the mortality rare from 50% to less than 1% (Sharma et al., 1997) Epidemiology of Cholera Early Pandemics Since the beginning of the first pandemic in 1817, seven cholera pandemics have occurred (Pollitzer,1959), excluding the seventh pandemic, which took place on the Indonesian island of Sulawesi in (65), pandemics occurred in the Indian subcontinent in the Ganges delta and spread to other countries over many years (Snow, 1855). In 1830, the epidemiological and public health approaches to cholera developed in the context of some understanding of the nature of certain infectious diseases, including smallpox and syphilis, with little agreed differentiation of the fevers. In his late 18th century doctrine, Benjamin Rush describes there was but one fever in the world (Shryock, 1936) had received broad support. Exciting factor in the cholera epidemic was sometimes considered as shaping existing fevers into its own image, and the arrival of cholera coincided with an increase in mortality and/or transferred deaths between categories was questioned. The second cholera pandemic of the early 1830s invaded the British Isles, and was marked by epidemiological observations made by John Snow on the waterborne cholera transmission in London between 1847 and 1854(Snow, 1855). Ships carrying Irish immigrants caused the second pandemic in Canada (Marian, 1957). During the third pandemic (1852-1859), cholera was raging in the United States, and during the 1870s at the end of the fourth pandemic, towns and villages along the Ohio, Missouri, and Mississippi, rivers experienced cholera (Billings et al., 1975). The fifth pandemic mainly affected South America; causing large epidemics in several countries with Argentina, Chile, and Peru suffering high casualties. (Gil et al. 2004). Robert Koch isolated the cholera bacterium, known as comma bacilli during the fifth pandemic in feces of patients in Egypt in 1883 and India in 1884(Koch, 1884). Between 1899 and 1923, the sixth pandemic involved populations expanded in the Balkan Peninsula and the Middle East (Pollitzer, 1959). Apart from a large epidemic in Egypt in 1947 (Shousha, 1947), cholera was confined to southern and Southeast Asia since the mid-1920s until the 1961 outbreak of the seventh pandemic in. Both the sixth pandemic and possibly the fifth pandemic were caused by V. cholerae of classical biotype. The Seventh Pandemic The seventh pandemic is considered the largest of the pandemic in the geographical distribution, and was caused by V. cholerae O1- biotype El Tor (Table 2). The 1961 pandemic first invaded the island of Sulawesi in Indonesia and spread to other islands, including Borneo, Sarawak Java, Taiwan, the Philippines, and Sabah. It affected the entire archipelago of South Asia at the end of 1962 (Kamal, 1974). , In Asian mainland, from 1963-1969, the pandemic affected Cambodia, Thailand, Vietnam, Malaysia, Burma, India, Pakistan, and Bangladesh. Cholera reached Pakistan shortly after El Tor, and outbreaks were reported in Iraq, Iran, Afghanistan, and in the neighboring republics of the Soviet Union (Kamal 1974). By 1970, El Tor cholera had reached the Arabian Peninsula, Syria and Jordan, and to a lesser degree, in Israel (Cohen et al., 1971). The seventh pandemic was in sub-Saharan West Africa in early 1970, causing explosive epidemics as a result of more than 400 000 cases of high mortality, attributed mainly a lack of background immunity of the population, and lack of healthcare infrastructures (Goodgame et al., 1975). During this epidemic, cholera invaded the coast and the interior through waterways and continued to spread to the interior of the Sahel countries by land to travel to nomadic tribes. During the 1970 cholera epidemic, 28 were newly affected were reported and 16 are in Africa (Kaper et al., 1995). In South America, the seventh pandemic which began in Peru in January 1991 caused a return of cholera to the continent after more than a century in an explosive epidemic (Levine, 1991) (Ries et al., 1992). Subsequently, neighboring Ecuador and Colombia also reported cholera epidemic. In each of these countries were people of low socio-economic status, lack of clean water and sanitation, the most affected (Pan American Health Organization, 1991). In April 1991 a small outbreak was reported in Santiago, the capital of Chile (Levine, 1991). Cholera then invaded more countries in South and Central America along the Pacific coast. The Pan American Health Organization estimated that during 1991 and 1992 there were 750,000 cases of cholera and 6,500 deaths in the Americas (Pan American Health Organization, 1991). Recently, the July 1994 outbreak in Goma, Zaire, (Siddique, 1995), is considered one of the worst outbreaks in recent history. Nearly a million people were displaced to Zaire and sheltered in refugee camps as a result of Conflicts between tribes in neighboring Rwanda. Outbreak of cholera in refugee camps affected by poverty caused an estimated 12,000 deaths among Rwandan refugees during a period of three weeks (Siddique, 1995). The seventh pandemic was active causing seasonal outbreaks in several developing countries. However, in 1992, V. cholerae belonging to serogroup non-O1 (now known as O139) caused massive epidemics of cholera in Bangladesh and India and spread to other countries, which could represent the beginning of the eighth pandemic Conclusion John Snow achievement was based on the logical organization of his remarks. He recognized a natural experiment, and its quantitative approach to the analysis of the occurrence of disease in human populations, which is actually a summary of the views of modern epidemiology. It has been over a century and a half since Dr. Snow had published his findings. And in spite the medical and epidemiological advancement in combating the disease, yet, the threat of cholera remains very real and cholera continues to be a global threat to public health and an important indicator of the lack of social development, especially in developing countries which suffer from lack of access to drinking water and lack of sanitation. The disease continues to challenge the increasing proportion of vulnerable populations living in unsanitary conditions, such as slums and refugee camps. The treatment centers and water purification units in poor nations are only interim measures, and steady decline in the spread of the illness should not be seen as a complete victory.

Sample Essay †The Role of Women Essay

The transition from early 19th century England to late 20th century Australia reveals an overwhelming shift in the dominant discourses and ideologies surrounding the role of women. While Jane Austen composed her seminal 1813 romance Pride and Prejudice against the social and historical backdrop of Regency England, a time when patriarchal ideals governed notions of femininity, Fay Weldon’s 1984 epistolary novel Letters to Alice bears the hallmarks of post-feminist women’s liberation and agency. However, through close examination of the intertextual connections woven between this pair of texts, it emerges that not only does Weldon’s text take form as a didactic treatise to her young nice that reflects her own contemporary views on women and women writers, her letters prompt an unquestioningly feminist re-reading of Austen’s representation of women in her own literary works. As a result, it is these connections that yield the recognition that despite the contextual divide separating this pair of texts, both authors are irrevocably bound in their purpose to didactically challenge the politically charged representation and role of women in their respective cultural spheres. Composed in the late 20th century – an era where feminist discourses of equality were deeply entrenched in political and academic spheres – Weldon’s text is narratively shaped as a didactic novel addressed to her fictionalised ‘green haired punk’ niece, using the epistolary form to both instruct and demonstrate the power of literature â€Å"with its capital L† to function as a vehicle for women to both change and challenge dominant social conventions and values. To achieve these means, it is no coincidence that Weldon is seen to appropriate the epistolary form – â€Å"a popular form of fiction at the time† used by female writers such as Austen herself- to create a intertextual connection that transcends the contextual gap separating each text to promote a specifically feminist view of writers and the function of â€Å"Literature†. Here, Weldon is herself the embodiment of her self-described breed of â€Å"strong women, wo men who work, think, earn, have independent habits†. Her authoritative didacticisms to the burgeoning writer Alice -â€Å"simply speak†¦and you will be listened to. And eventually,  even enjoy your captive audience† – symbolically demonstrate the legacy of feminist ideals that were initially catalysed through early Regency female authors such as Austen whose patriarchal context kept their revolutionary works â€Å"shelter[ed] behind the cloak of anonymity†. Given the modern context of Letters to Alice, it is undeniable that Weldon writes from a discourse of female agency when she informs Alice that to enter the â€Å"immortal† â€Å"City of Invention†, she must metaphorically â€Å"swim against the stream of communal ideas† and â€Å"demonstrate to the reader the limitations of convention† that societies inscribe upon its populace as â€Å"unquestioned beliefs†. The strong tone employed in such directives highlight that from Weldon’s feminist perspective, the value of female authorship and literature is derived from the capacity of one’s own personal value system to morally guide or catalyse a transformation in its readership: â€Å"Readers need and seek moral guidance†¦They need an example, in the light of which they can examine themselves, [and] understand themselves.† Simply put, Weldon’s Letters to Alice is a text that is highly political in purpose; it prompts a strong consideration of the function of literature to catalyse notions of female empowerment through both changing and challenging dominant social conventions and values. Taking into account Weldon’s didacticisms regarding female authorship and social change, it becomes apparent that the intertextual connections to Jane Austen weaved within Letters to Alice prompt an undeniably feminist re-evaluation of her representation of Elizabeth Bennet in Pride and Prejudice. While separated by the historical divide of almost two centuries, Weldon’s instruction for her niece to â€Å"swim against the stream of communal ideas† can be seen to resonate in Austen’s idealistic protagonist Elizabeth Bennet, a character who transgresses against the dominant values that governed Regency England; and whose personal virtues triumphed over the restrictions of her era. Weldon’s didactic assertion that female author’s must work to â€Å"demonstrate to the reader the limitations of convention† undeniably connect with and transform perceptions of Austen’s Elizabeth, framing and augmenting her personal values of rationalit y and wit as they shine through the text. This is particularly evident through her strong authoritative tone in declarative statements: â€Å"I shall be very fit to see  Jane – which is all I want†, which work alongside uncharacteristic images of female activity: â€Å"springing over puddles to with impatient activity [gave her] a face glowing with the warmth of exercise† to undermine a social value system that links feminine propriety with explicit passivity. Such aspects of her character are further augmented through Austen inscribing Elizabeth’s dialogue with a strongly comedic tone of satire and irony. She delights in intellectually challenging the supposedly superior intellect of Mr Darcy in a series of playful exchanges: â€Å"I am convinced that one good sonnet will stave [love] entirely away†; â€Å"your defect is to hate everybody†. In considering these connections, Weldon’s text can be seen to invoke a renewed reading of Elizabeth, positioning her as a didactic figure that planted the early seeds of feminist discourse from which Letters to Alice was composed: â€Å"[She] pay[ed] paying attention to the subtle demands of human dignity rather than the cruder ones of established convention†¦prodding [civilisation] quicker and faster along the slow difficult road that has led us out of barbarity into civilisation† Ultimately, examination of the intertextual connections between Letters to Alice and Pride and Prejudice yield a recognition that while Weldon’s text instructs young Alice on contemporary views on women and women writers from a late 19th century context, it also catalyses a re-evaluation of Austen’s representation of Elizabeth Bennet, reframing interpretations of her character as one who challenges the dominant value systems of gender. As a result, it is these connections that incite the realisation that despite the contextual divide separating this pair of texts, both authors are irrevocably bound in their purpose to didactically challenge the politically charged representation and role of women in their respective cultural spheres.

Romeo and Juliet Balcony Essay

A Tragic Story of Two Lovebirds William Shakespeare’s Romeo and Juliet is a well-known and phenomenal play of tragedy. The reason for its fame is that not only is it just dreadful, but there is also a romantic element as well. The play is set in Verona, Italy during the Elizabethan Age with two young and innocent lovers, Romeo and Juliet, from different wealthy families, Montague and Capulet. However, these two households share a hostile bond with each other that goes deep in Verona’s history.In one of the acts there is the famous â€Å"balcony scene† which takes place at night with Juliet on her balcony and Romeo down at her father’s orchard. This scene stands out from the rest because this is where Romeo and Juliet exchange their vows of undying love. During the balcony scene, Shakespeare uses personification, metaphor, and simile to help convey Romeo and Juliet’s deep affection for one another. While Juliet confesses her private thoughts alone, R omeo describes her stunning beauty and his feelings of love through personification.As Romeo gazes at her, he describes that her cheeks â€Å"would shame those / stars† (2. 2. 19-20). Her looks give off a special radiance that makes him say her cheeks outshine the eternal light given from the stars. By using stars, her beauty gives him hope, light, and a sense of goodness into his existence. This suggests that her brightness gives a certain direction that leads his life in a positive way. Then, Romeo argues that â€Å"stony limits† will not stop his love because â€Å"what love can do, that dares love attempt† (2. 2. 72. 73). Since Romeo is in his lover’s and foe’s house, he does not mind risking his life for her.His action is what a true lover does because an ordinary stranger or friend never bothers doing it. If his feelings are a physical object, it can be so strong that not even hard stone can prevent it. Shakespeare’s personification he lp show that Romeo’s love is pure, which implies Juliet is the one for him. Juliet explains through a metaphor and simile that her feelings will not change even though Romeo is from the enemy’s house. She compares his last name, Montague, to a rose and says that â€Å"any other word would smell as sweet† (2. 2. 47).With the fact the Capulets regard Romeo as an enemy, she still loves him no matter the reason because adding an evil household name to Romeo does not change him at all. By using roses, it symbolizes the sweet and passionate love she has toward him. To prove it even further, Juliet declares her emotions are â€Å"as boundless as the sea† (2. 2. 140). This illustrates her love for Romeo is infinite and immeasurable like the sea. In reference to nature, this also represents her adoration is natural, not of greed or lust. By using figurative language, Juliet effectively shows her feelings of love to Romeo.In the renowned play Romeo and Juliet, Shak espeare shows the two lover’s devotion through the use of figurative language. On Romeo’s side, he uses personification to praise Juliet’s certain attributes and vividly describe his affection towards her. In Juliet’s perspective, she uses a metaphor and simile to explain her passion for Romeo and how she does not consider him as a rival. Without Shakespeare’s use of figurative language, the audience cannot know how deep and real their innocent love is. In addition, the absence of these literary devices could make the play dull and not as dramatic.
