Nervous system science and Neurosurgery Nervous system science Overview Despite the fact that our essential intrigue is with the Medial Transient Lobe, additionally called the V5 zone, a conversation of the whole movement discernment pathway is educational. Movement discernment really starts with the particular visual receptors in the retina known as M-cells (from the Latin word magnus, for enormous). As the name infers, the M-cells are moderately huge, situated in the fringe retina, and react rapidly to transient visual incitement making them obviously appropriate for movement location. Paradoxically, P-cells are littler, situated in the fovea, respond all the more gradually to improvements, what's more, are fit to fine-detail vision. Motivations from the retina at that point travel through the optic nerve to the optic chiasm where filaments of the optic nerve from the inward (nasal) half of every retina cross while those all things considered (transient) half of every retina remain on a similar side. This halfway crossing is an element of well evolved creatures, while for most vertebrates underneath well evolved creatures, all the filaments cross. It must be called attention to that no movement preparing is really done in the optic chiasm. About 20% of the axons leaving the optic chiasm go to the Superior Colliculus, which is answerable for certain eye developments and spatial confinement. The staying 80% of the axons go to the Lateral Geniculate Core, LGN (Schiffman, 2000, p. 71-73). The LGN speaks to the following movement handling step after the M-cells in the retina. The Magnocellular Division of the LGN explicitly forms the motivations from the M- cells in the retina and is interestingly fit to recognizing little differentiations among light and dim territories along these lines improving three-dimensionality and movement ef... ..., J.

Effect of economy on culture and social structure

Impact of economy on culture and social structure Presentation As social orders develop, network individuals and neighborhood authorities are persistently gone up against by the craving to adjust social, financial, natural, and monetary objectives. They face the test to settle on the sum and types of the new improvement that the general public can go up against so that not to put lives of the individuals from the network at risk.Advertising We will compose a custom paper test on Effect of economy on culture and social structure explicitly for you for just $16.05 $11/page Learn More Thus, financial effect assessment is proposed to help social orders in dynamic, which thusly advances long-go maintainability, monetary thriving, social prosperity and a sound network (Edwards, 2009). Social structure, especially in interpersonal organizations, impacts monetary outcomes for three significant reasons. To start with, the interpersonal organizations decide the quality and stream of data. Most data is nuanced, inconspicuous and difficult to a ffirm. Consequently, players don't think about indifferent sources but instead depend on people they know about. Second, informal communities are an imperative wellspring of directing assessment. This is of significance in light of the fact that the hugeness of discipline or prize is much of the time amplified dependent on their impact in the event that they originate from known people. At long last, trust develops with regards to an informal organization. In this way, in today’s world, any issues attached to financial matters assume a significant job in molding the thoughts of culture and social auxiliary systems in the general public (Granovetter, 2005). Financial structure and culture Economic models normally assume that representatives pick work scanning for advantages and costs that are leveled at edge. Nonetheless, in any real work showcase, informal organizations have a significant job. Potential representatives and bosses want to gain from one another, for example fro m singular sources which have data that they trust, for example, social capital (Granovetter, 2005). Social cooperation transmits data on representatives, bosses and occupations which streams continually through the informal organizations. These systems are kept up by numerous individuals to a great extent for the non-financial reasons. Ordinarily, individuals utilize existing interpersonal organizations and contacts, implying that there as a rule is no requirement for making any monetary interest in such systems. This diminishes the expenses beneath endorsed mediators. Prior informal communities are inconsistent appropriated in different ways prompting inconsistent playing ground in labor markets without connecting any player (Granovetter, 2005).Advertising Looking for article on sociologies?

In any case, one’s spot in any social gathering may affect the efficiency, for some reasons. To start with, numerous errands must be cultivated through a genuine cooperation from others, second is that few undertakings are excessively muddled and sensitive to be done â€Å"by book† and need â€Å"tacit knowledge† practice appropriate just however collaborating with learned people. Since great connection with each other is crucial, this implies those joining the organization through individual contacts become pioneers and increasingly beneficial, just as keep away from blunders that may hold-up the untouchables (Granovetter, 2005). People do exchange with one another and the impact of knowing each other regarding value contrasts with their affiliation, the moving of cost to different accomplices and market situation. To grasp how varieties from harmony cost may happen, one ought to assess both financial aspects and humanism of situation. A diffe rence in the exchanging accomplices is less or all the more hard under shifting circumstances and depends on noneconomic and monetary expenses of isolating long-term ties alongside accessible social alternatives. In this way, the monetary flexibility of the structure depends on social development of exchange relations and is unusual without the information on that social structure (Granovetter, 2005). End The models of economy might be disentangled if relations of economy with the non-monetary highlights of the public activity remain inside the black box; such procedure conceptualizes from a few social events that unequivocally impact costs and the current strategies of the financial activities.

What does the achievement of Despacito prove in Essays - Music

What does the accomplishment of Despacito demonstrate in Essays - Music What does the accomplishment of Despacito demonstrate in the diversion world that is overwhelmed by English language? Do you feel that everybody who streams, downloads and appreciates the tune completely comprehends the verses? Bolster your answer with some proof. What is picked up and what is lost if the tune is converted into English? How far does the craftsman's social foundation influence the melody verses? Bolster your answer with some proof. This implies despite the fact that the amusement world is ruled by English language, there are still possibilities for other language to command the universe of diversion if the melody or film created is agreeable and acceptable to hear, anyway it relies upon various individual's viewpoint. Also, in view of our conclusion, we concur that Despacito' is a decent tune to hear as it has an extremely infectious tune which permits us to pick up the roused soul and even make us begin to move, it's simply practically inconceivable not to move when you hear the track, regardless of whether you're not an artist. The manner in which the chorale begins Des-Pa-Ci-To is anything but difficult to recall. The Spanish language additionally coordinate with the music which is great to hear. Despacito is begun by Luis Fonsi and Daddy Yankee from Puerto Rico yet when he teamed up with Justin Bieber, the track h ave collected more than 4.6 billion streams over all stages since its discharge in January. Pr ior to discharging this melody, Justin Bieber is one of the prestigious Canadian artist who delivered well known tracks which consistently hit the iTunes top outlines. By this implies, by taking a gander at the fame he got, we can undoubtedly tell that he can make the Despacito' single significantly more mainstream and far reaching. No. Despacito is composed and sung in Spanish, and this implies not all people in this world can comprehend what the verses really mean as Spanish isn't a worldwide language. Spanish might be spoken in certain nations, for example, Europe, Southern America and even some in China. Be that as it may, contrasted with Spanish, English is progressively all inclusive. For instance, in Asia, Spanish isn't that basic for what it's worth in other district of the world, individuals will in general communicate in their own nearby language or English. In light of our exploration, the most stream of Despacito' goes to UK and other European nations. From this, On the off chance that the tune is deciphered in English, the melody will be dubious on the grounds that the verses contain some express substance which is kinda strange to clarify it in English. The two of us have inquired about certain realities on what the Despacito' tune truly implied and the verses may not suit with certain individuals when it's deciphered in English. Nearly everybody in this period gets English, a few people may imagine that it's not reasonable for children to hear it. In any case, since it's composed and sung in Spanish, heaps of individuals got no intimation of what it truly mean. Both Luis Fonsi and Daddy Yankee originate from Puerto Rico and we can found the line This is the means by which we do it down in Puerto Rico ' which shows that there is connection between their nation of origin and the verses made. Another proof is that them two are latin american and it recommends why the verses are initially set in Spanish.

Instrumentalism Underdetermination Realism - Free Essay Example

Understanding Underdetermination in conjunction with realism and instrumentalism The present essay is about the understanding of under determination thesis in conjunction with the realism and instrumentalism. As we know that realism and instrumentalism are two opposite views in philosophy of science, so by explaining the two it would be much easier to grasp the concept of under determination thesis, which is one of complex doctrine. The intended audiences of this essay are science students and people who are interested to know about the philosophical issues in science. I divide the essay into four of parts. The first part explains the realism and instrumentalism concepts, second part explains the under determination thesis in detail and then the third part will state the views of different philosophers about three schools of thoughts. The fourth and the final part conclude the whole argumentation Realism The word realism in the dictionary means the tendency to view or represent things as they really are. [dic]. In philosophy of science it can be defined as â€Å"the philosophical doctrine that abstract concepts exist independent of their names†. It can be explained as an approach in philosophy that considers objects as they are in the universe as real things and their characteristics as a secondary thing. The advocate of realism are called realist and it is important to differentiate the realists. A person can be realist about the different kinds of things i.e. mountains, physical objects, numbers, universe etc. but in the case of a philosopher, it is required to specify that for what object/thing the philosopher is realist [book]. An American philosopher name Hilary Putnam stated that â€Å"A realist with respect to a given theory holds the following: What makes them true or false is something external that is to say, it is not in general our sense data, actual or potential, or the structure of our minds, or our language, etc. Furthermore he says that the positive argument for realism is that it is the only â€Å"philosophy that does not make the success of science a miracle†. [Book]. Generally, in science established scientific theories are treated as a true fact, but according to realist these theories would be treated as a successful explanation of the whole scientific process or its relation to an object, and not as a whole truth. [Book] An example is that sun, mountains, building etc. exists in this world, but the attributes like length, width, colour etc. are either dependent or independent of the environment. For example the sun is spherical in shape, so it is independent from any material thing of this universe. But in case of a building, its shape and size, all depend upon the person who designed or built it. So it can be said that reality is related to mind and environment. In general, Realism is supposed to be a term that relates to number of subjects i.e. ethics, aesthetics, causation, modality, science, mathematics, semantics etc. When we talk about the realism in the context of science then the intention is to elaborate the scientific realism which has a number of dimensions i.e. metaphysical, epistemological and methodological. Besides this it is also the truth that there is no single version of scientific realism which is being accepted by all the scientific realists. The doctrine of scientific realism states that â€Å" the world studied by science exists and has the properties it does, independently of our beliefs, perceptions, and theorizing; that the aim of science is to describe and explain that world, including those many aspects of it that are not directly observable; that, other things being equal, scientific theories are to be interpreted literally; that to accept a theory is to believe that what it says about the world is true, and that by continually replacing current scientific theories with better ones. Science makes objective progress and its theories get closer to the truth†. Realism has two schools of thought, first one is called Extreme realism, represented by William, a French philosopher; according to him â€Å"universals exist independently of both the human mind and particular things†. The second one is moderate realism and according to which â€Å"universals exist only in the mind of God, as patterns by which He creates particular things†. The main proponent of this view was St. Thomas Aquinas and John of Salisbury. According to epistemological view of realism, things exist in this universe, independent of our understanding or perception. This point is totally opposite to the theory of idealism, which states that â€Å"reality exists only in the mind†. By having a brief explanation of realism, instrumentalism will be discussed, which is the opposite view of realism and most of time call ed Antirealism. Antirealism is a doctrine that rejects realism, and includes instrumentalism, conventionalism, logical positivism, logical empiricism and constructive empiricism. Instrumentalism Instrumentalism is treated as a doctrine that states â€Å"theories are merely instruments, tools for the prediction and convenient summary of data† [Book]. In other words it can be defined as â€Å"concepts and theories are merely useful instruments whose worth is measured not by whether the concepts and theories are true or false, but by how effective they are in explaining and predicting phenomena†. The point is that in order to make predictions from theories, logic is required, so it can be hard to say theories have no truth values. In view of this instrumentalists admit that theories have truth values, but do not accept this argument that theories should be treated as accurately true. In view of this T.S. Kuhn said that â€Å"Theories may have truth values but their truth of falsity is irrelevant to our understanding of science†. [Book] In other words instrumentalism evaluates the significance of a theory with respect to empirical evidence and di d not require the understanding of the actual phenomena. For example Newton gravity model is understandable and working fine, but it has no theoretical foundation [Answer.com] The another aspect of instrumentalism is that it relates closely to pragmatism and this point of view opposes the scientific realism because according to this, theories are more or less true in nature. Moreover, instrumentalism refutes that theories can be evaluated on the basis of truth. Theories will not be perceived as air plane black box which gives output on the basis of observed input. The point is that there should be a clear distinction between theory and observation that further leads to a distinction between terms and statements in each type. Like in science for statement of observation there is a specific meaning for an observable truth, for example if the litmus paper is red, so the observation terms have their meaning fixed by their referring to observable things or properties, e.g. red . Theoretical statements have their meaning fixed by their function within a theory and arent truth evaluable, e.g. the solution is acidic, whereas theoretical terms have their meaning fixed by their systematic function within a theory and dont refer to any observable thing or property, e.g. acidic. Though you may think that acidic refers to a real property in an object, the meaning of the term can only be explained by reference to a theory about acidity, in contrast to red, which is a property you can observe. Statements that mix both T-terms and O-terms are therefore T-statements, since their totality cannot be directly observed†. There is some criticism of this distinction, however, as it confuses non-theoretical with observable, and likewise theoretical with non-observable. For example, the term gene is theoretical (so a T-term) but it can also be observed (so an O-term). Whether a term is theoretical or not is a semantic matter, because it involves the differe nt ways in which the term gets its meaning (from a theory or from an observation). Whether a term is observable or not is an epistemic matter, because it involves how we can come to know about it. Instrumentalists contend that the distinctions are the same, that we can only come to know about something if we can understand its meaning according to truth-evaluable observations. So in the above example, gene is a T-term because, although it is observable, we cannot understand its meaning from observation alone. The explanation of realism and instrumentalism above has provided us the capability to understand the topic with much insight. Now, I switch to under determination thesis. From the above discussion we have the knowledge that instrumentalism is related to pragmatism and this point of view is in contrasts with the scientific realism, which states that theories are often more or less true. Here, I refer to Quine, who said that theories can be underdetermined by all poss ible observations [23], and Newton Smiths, treat this as a threat to realism. He said, realism in his sense has to be rejected if there can be cases of under determination of theories. Under determination As we know that under determination is a thesis that is â€Å"used in the discussion of theories and their relation to the evidence that is cited to support them†.[1] Arguments from under determination are used to support epistemic relativism by claiming that there is no good way to certify a theory based on any set of evidence. A theory is underdetermined if, given the available evidence, there is a rival theory which is inconsistent with the theory that is at least as consistent with the evidence. Moreover, under determination is treated an epistemological issue about the relation of evidence to conclusions. Historical background The subject gets its first attention by Renà © Descartes, a French philosopher and mathematician in the 17th century. He presented two arguments related to under determination. â€Å"While dreaming, perceived experiences (for example, falling) do not necessarily contain sufficient information to deduce the true situation (being in bed)†.[2] As we know that it is not always possible for a person to separate dreams from reality and the theory that what is real or dream at a certain time is underdetermined. The second argument of Descartess is called demon argument â€Å"which is a variant of the dream argument that posits that all of ones experiences and thoughts might be manipulated by a very powerful being (an evil demon) that always deceives. Once again, so long as the perceived reality appears internally consistent to the limits of ones limited ability to tell, the situation is indistinguishable from reality, one cannot logically determine between correct bel iefs from being misled; this is another version of under determination†.[2] The second person who talks about under determination was David Hume, who does not use the word under determination specifically but an argument about the problem of induction. I will discuss the induction later in the essay while explaining the under determination types. The Under determination thesis gets the recognition in the twentieth century through the work of Thomas S. Kuhn, who is a famous theoretical physicist and philosopher. He was very much prominent due to his work, The Structure of Scientific Revolutions that offered an alternative to linear models of scientific progress. According to Kuhn the under determination has a place to for argumentation against theories in the philosophy of science, and scientific realism. According to Khun the under determination can be divided into two types the weak and strong under determination. The both could be stated in the following words: Weak underdetermined is that the currently available evidence is not sufficient to prove the argument, but some evidence that will be available in the future might do this. Strong underdetermined is to claim that it is principally impossible to get evidence that could fully resolve the argument between the opponent theories. Besides strong and weak underdetermined theory there are two other attributes called deductive and inductive under determination. The two rival theories could be deductively underdetermined when the available evidence does not completely deny either theory. The theory is inductively underdetermined when theories are compatible with the available evidence, but still tries to determine, which theory could be a better failure A weak under determination can turn to a strong one if it avoids the attainment of future evidence that turns it into deductive under determination. A counter argument is that it is not possible for a theory to be accurately stro ng and inductive. In general weak under determination arguments are focused on the availability of evidence for an explicit set of theories, and strong under determination mostly entails common epistemological arguments that relates to the type of evidence and its viability for a particular or general theory. Furthermore, it is generally acknowledged that all theories are weakly underdetermined, but in case of some specific purpose all theories are strongly underdetermined. Explaining the types of under determination thesis, Ludan said that â€Å"for any finite body of evidence, there are indefinitely many mutually contrary theories, each of which logically entails the evidence†. So in other words it can be said that deductive under determination is under determination of selecting theory through a logical method. Finally, the term under determination as thesis is associated with two respectable names Pierre Duhem and W.V. Quine in philosophy of science, â€Å"t hat neither the truth nor the falsity of any scientific theory is determined by evidence†. According to Duhem-Quine Under determination is a â€Å"relation between evidence and theory. More accurately, it is a relation between the propositions that express the (relevant) evidence and the propositions that constitute the theory. Evidence is said to underdetermine theory†. From the above it can be said that evidence is not enough to prove the theory, belief or truth. Moreover, only the availability of evidence is not enough to make the theory a credible one. In view of this we can call the first argument a deductive and the second inductive under determination. Hence, according to under determination thesis, both arguments have required some definite epistemic proposition, and belief in a theory could not be justified on the basis of evidence. For under determination types, Duhem, also said that â€Å"logic alone cannot take us from the falsification of a pred iction to a refutation of an isolated hypothesis. Importantly, deductive under determination does not mean that theory choice is underdetermined, nor does it mean that there is more than one reasonable conclusion given certain experimental evidence†. Up until now we have a basic understanding of the under determination thesis, so now I will discuss what realism actually is, the theoretical frame and the origin of the concept. Another argument against scientific realism, deriving from the under determination problem, is not as historically motivated as these others. It claims that observational data can in principle be explained by multiple theories that are mutually incompatible. Realists counter by pointing out that there have been few actual cases of under determination in the history of science. Usually the requirement of explaining the data is so exacting that scientists are lucky to find even one theory that fulfils it. Furthermore, if we take the under det ermination argument seriously, it implies that we can know about only what we have directly observed. For example, we could not theorize that dinosaurs once lived based on the fossil evidence because other theories (e.g., that the fossils are clever hoaxes) can account for the same data. Realists claim that, in addition to empirical adequacy, there are other criteria for theory choice, such as parsimony. In particular, it must not be confused with what Newton-Smith takes to be a minimal common factor among the wide range of philosophers who in recent years have advocated a realist construal of scientific theories. This common factor consists of the following theses: (1) Scientific theories are either true or false and which a given theory is, it is in virtue of how the world is, (2) If a theory is true, the theoretical terms of the theory denote theoretical entities which are causally responsible for the observable phenomenon whose occurrence is evidence for the theory, (3) We can have warranted beliefs (at least in principle) concerning the truth values of theories, (4) The historically generated sequence of theories of a mature science may well be a sequence of false theories but it is a sequence in which succeeding theories have greater truth-content and less falsity content than their predecessors. We may refer to (1) as the objectivity, (2) as the causality, (3) as the decidability, and (4) as the convergence of scientific theories. Newton-Smith uses the name realism for the combination of these four theses, and he also seems to hold that this is the standard use of the term. It is clear that theoretical realism in the weakest sense entails neither objectivity, nor causality, nor decidability, nor convergence. In particular, some theoretical propositions may be true even if no scientific theory as a whole is either true or false. Moreover, it is doubtful whether realism in Newton-Smiths sense entails theoretical realism. For e xample, if all theoretical propositions are false, then theoretical realism is false, but realism in Newton-Smiths sense might still be true. In any case, one of Newton-Smiths main theses is that realism in his sense has to be rejected if there can be cases of under determination. In particular, he claims that either objectivity or decidability has to be weakened if under determination can occur to give up decidability is what he calls the ignorance response (to under determination). This involves embracing the possibility of inaccessible facts facts concerning whose obtaining we could have no information. To give up objectivity is what he calls the arrogance response. This amounts to holding that if we cannot know about something there is nothing to know about. 36 Notice, that this holds only for under determination in Newton-Smiths sense, i.e. under determination by all possible data. It does not hold for the other kinds of under determination mentioned above. In other words, it is only when an underdetermined theory is empirically viable that we cannot know that it is true or that it is false (either because it is neither true nor false, or because we cannot know, even in principle, what its truth value is). In general, we cannot have under determination (of any kind) together with empirical viability, objectivity, and decidability. If a theory is underdetermined, we cannot know that it is true. This I accept. At first, it appears that Quine would not accept this. He holds that there may be two best total theories which are empirically viable and incompatible, but that we may know, at least in principle, that one of them is true and the other false. However, it seems that Quine is then using true and false in a non-realistic sense; according to him, to call a statement true is just to reaffirm it. He does not seem to assume that there is some objective reality, the world, such that the truth of a statement consists it its correspondence with this reality. Hence, presumably he would reject the objectivity thesis which is part of realism in Newton Smiths sense. Realism/Anti-realism Given the various epistemological difficulties (under determination, problem of induction, rationality, social forces), and the lack of a consensus on these issues, why should we think that our theories are actually describing reality? The apparently large gap between observational and theoretical knowledge inspires worry about realism Metaphysical difficulties come into play here as well—we do not have good understandings of the nature of laws and causation, explanation, so how can we claim that we are discovering the nature of the universe?

Agents that Inhibit Stem Cell-resistant Chemotherapy - Free Essay Example

As cancers are heterogeneous, drug discovery efforts are aiming to increase patient survival and will surely need to consider the plasticity of cancer cells (Singh and Settleman, 2010). Cancer stem cells have a higher intrinsic resistance to chemotherapy than do normal cancer cells, and may be the source of post-therapy relapse (Thomas; et al, 2014). New agents were discovered as anticancer drugs to destroy cancer stem cells that are resistant to chemotherapy. This review paper will focus on some important agents, and these are: Resveratrol, Histone Deacetylase Inhibitors, Disulfiram and metformin. Don’t waste time! Our writers will create an original "Agents that Inhibit Stem Cell-resistant Chemotherapy" essay for you Create order The first agent is Resveratrol. â€Å"Resveratrol is a polyphenol non-flavonoid compound present in strongly pigmented vegetables and fruits† (Pintea and Rugin?, 2014). This compound has antitumor effect. It works by inhibiting tissue necrosis factor beta (TNF- ?) pathway that activates tumor growth. It also suppresses the formation of cancer stem cells of colorectal cancer. The unique feature about this agent is that it sensitizes cancer stem cells to 5-FU. (Buhrmann et al., 2018). Secondly, mentioning Histone Deacetylase (HDAC) Inhibitors. This class of agents has a significant role in suppressing cancer stem cells of different cancer types by various mechanisms, but not all of them are fully explained. One of these mechanisms is reprogramming gene expression in cancer cells, thus leading to growth arrest and apoptosis. Another mechanism is suppressing self-renewal capability and activating the differentiation of cancer stem cells, resulting in enhanced sensitivity to chemotherapy. There is evidence that these agents can aid the deacetylation of non-histone targets related to cancer stem cells homeostasis; making it target-specific (Lin et al., 2018). Thirdly, the anti-alcoholism drug Disulfiram was approved for targeting resistant cancer stem cells in both in vivo and in vitro. Disulfiram is aldehyde dehydrogenase (ALDH) inhibitor. It inhibits both ALDH1A1 and ALDH2 isoforms and has shown anti-CSC effects in breast cancer. In addition to ALDH inhibition, it inhibits proteasome and E3 ligases, and considered as DNA-demethylating agent. â€Å"This drug has reached phase II clinical trials in the treatment of BGM† (Liu et al., 2013). Finally, the unexpected agent in inhibiting resistant cancer stem cells (CSC) is metformin. This agent has shown anticancer effect especially against CSC in addition to its antidiabetic effect. Metformin selectively inhibits CSCs via targeting of the AMPK/mTOR/PI3K, insulin/IGF1, Ras/Raf/Erk, Shh, Wnt, TGF?, Notch, and NF-?B signaling pathways, which have many tasks in cell proliferation, self-renewal, differentiation, metastasis and metabolism. It’s important to notice that even metformin –as monotherapy or in combination with chemotherapy- has anti-CSC activity; further clinical trials are needed for additional emphasis of this effect (Saini and Yang, 2017). To conclude, cancer stem cells are more resistant to conventional chemotherapeutics than the majority of cancer cells, and survival of cancer stem cells likely contributes to tumor recurrence. Theoretically, eliminating cancer stem cells through targeted therapies would increase the efficacy of our existing treatments and lead to more favorable long-term prognoses for many cancer types. Drug discovery nowadays is directed towards cancer field and aims to treat cancer and prevent cancer relapse via targeting cancer stem cells. Some agents were existed before like Disulfiram and metformin, and other agents are totally new.

Personal Responsibility At A Young Age By Environmental Or...

Personal responsibility starts at a young age by environmental or parental influence. You are either taught personal responsibility as you grow into an adult by being held accountable for your own actions or the responsibility is taken from you. As an adult, you are responsible for every action that you take, but before that action comes a series of thoughts that lead you to taking that action. Depending on how you were brought up, your transition into becoming an adult can either be an easy one or a difficult one. As an adult, the one thing that I have learned is a constant is that you will be held accountable for your actions whether you like it or not. Holding yourself accountable and having self-discipline has a lot to do with personal responsibility in my opinion. When you hold yourself accountable for your actions you are making a conscious effort to be a responsible person. Every action starts with a thought, whether it’s a good thought or a bad thought, it will determine the outcome of that action. For example, when you wake up in the morning and the first thought that comes to mind is that you will have a bad day, whether you know it or not you are subconsciously going to make it a bad day. If you stopped that thought when it happened and told yourself that today will be a good day you have already turned the outcome around. By holding yourself accountable you are in control, you are not aimlessly going through life reacting to what happens to you.

Problems with Learning English in My Country free essay sample

Problems with learning English in my Country Nowadays, English is our international language, the importance of English cannot be denied. With the help of developing technology , English has been playing major role in many aspects, such as, economy, technology, politics, and education. English is also used in many international events, such as seminar, public discussion. Although English is commonly used in the world, in Indonesia especially, English is rarely used in the society. For example, students only used English in school while the English subject is being learned, they never used it in their family or their society. That is one of the problems learning English in my country, Indonesia. And I think the other problems are the less interest and the lack confidence to learn English. Firstly, the less interest in learning English. People just haven’t realize that English is important things that must be mastered in the modern world, we can’t deny that. We will write a custom essay sample on Problems with Learning English in My Country or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Maybe most of the people just think that English is just complement thing and we don’t need to master that. But from what I believe, English can take us anywhere, just like my English lecturer said. I think, what every school must do is encourage their student to learn English seriously, as serious as they learn math, science and many other subject that interest the student. But the problem is that in Indonesia, we can’t just pick our favorite subjects, we are all forced to learn every subjects in school. And the students can’t focus and improvising their talent and interest to their favorite subjects (Sorry a bit out of topic). But let’s back to the topic, so the importance of English should be introduced to everyone, and the interest itself will come from people who understand that. Secondly, since we know the importance of English, we still face a problem, it is the lack of confidence in learning English. Some people have no confidence to speak and write in English, even that they are interested in English. They afraid they will have a bad pronunciation when speaking, and a wrong grammar in writing, and if everyone realize his/her mistake they will get laughed from everyone in class, that’s one of Indonesian bad culture. Obviously, the confidence of people who get laughed at will reduced. We should stop that bad culture, the wrong one should be corrected and encouraged. And I guarantee he/she will enjoy learning English because of that.

Civil War - Battle of Chancellorsville

Civil War - Battle of Chancellorsville Dates: April 30-May 6, 1863 Other Names: None Location: Chancellorsville, Virginia Key Individuals Involved in the Battle of Chancellorsville: Union: Major General Joseph HookerConfederate: General Robert E. Lee, Major General Thomas J. Jackson Outcome: Confederate Victory. 24,000 casualties of which 14,000 were Union soldiers. Significance of the Battle of Chancellorsville: This battle was considered by many historians to be Lee’s greatest victory. At the same time, the South lost one of its greatest strategic minds with the death of Stonewall Jackson. Overview of the Battle: On April 27, 1863, Union  Major General Joseph Hooker attempted to turn the Confederate left flank by leading the V, XI, and XII Corps across the  Rappahannock and Rapidan Rivers above Fredericksburg, Virginia. Passing the Rapidan via Ely’s Fords and Germanna, the Union forces  concentrated near Chancellorsville, Virginia on April 30 and May 1. The III Corps was to join the army. General John  Sedgwick’s VI Corps and Colonel Randall L. Gibbon’s division remained to keep up appearances against the Confederate forces gathered at Fredericksburg. Meanwhile, General Robert E. Lee left a covering force commanded by Major General Jubal Early in Fredericksburg while he  marched with the rest of the army to meet the Union forces. As Hooker’s army worked its way toward Fredericksburg, they encountered increasing Confederate resistance. Fearing through reports of large Confederate force, Hooker ordered the army to stop the advance and concentrate again at C hancellorsville. Hooker adopted a defensive posture which gave Lee the initiative. On the morning of May 2, Lieutenant General T.J. Jackson directed his corps to move against the Union left flank, which was reported to be separated from the rest. Fighting was sporadic across the field throughout the day when Jackson’s column reached its destination. At 5:20 pm, Jackson’s line surged forward in an attack that crushed the Union XI Corps. Union troops rallied and were able to resist the attack and even counterattack. Fighting eventually ended due to darkness and disorganization on both sides. During the nighttime reconnaissance, Jackson was mortally wounded by friendly fire. He was carried from the field. J.E.B. Stuart took temporary command of Jackson’s men. On May 3, the Confederate forces attacked with both sides of the army, massing their artillery at Hazel Grove. This finally broke the Union line at Chancellorsville. Hooker withdrew about a mile and entrenched his men making a  defensive â€Å"U.† His back was   to the river at United States Ford. Union generals Hiram Gregory Berry and Amiel Weeks Whipple and Confederate General Elisha F. Paxton were killed.  Stonewall Jackson soon died from his wounds.  During the night between  May 5-6 Hooker recrossed to the north of the Rappahannock,  due to Union reverses at Salem Church.

Statistics paper - Essay Example ere chosen for discussion in this statistics paper from the works of Bennett (2004), Greenblatt (2002), Hiller, Knight, Rao and Simpson (2000), Makkai and Payne (2003), Niazi, Pervaiz, Minhas and Najam (2005), Wei, Makkai and McGregor (2003), and Young, Dembo and Henderson (2007). The Bennett (2004) study began in 1996 to ascertain the prevalence of drug usage among offenders in the United Kingdom, and to trace whatever links there are between drugs and crime in relation to arrestees. This study was patterned after the Drug Use Forecasting (DUF) program of the United States Department of Justice. Like the DUF program, the Bennett (2004) research is being carried out using interviews and drug tests as the key methodology. The following substances are being tested as part of the large-scale drug research : amphetamines (including ecstasy), benzodiazepines, cannabinoid metabolite, cocaine metabolite (including ‘crack’), LSD, methadone, opiates (including heroin) and alcohol. The Bennett (2004) research used both descriptive and inferential statistics. Measures of central tendency including the range, median, proportion, frequency, percentage were used to describe the prevalence of drug use among the arrestees. The range was used to describe the length of the interval which contains all the data. The range also indicates dispersion of the data. Arrestees who tested for cannabis, for example, ranged from 36 per cent to 58 percent across the five survey area (p. 17). The proportion states the relationship of one part of a measure compared to a whole. In this study, proportion was oftentimes used to depict the picture of the size of the populations of arrestees testing positive for any of the eight substances in the aforementioned paragraph, such as â€Å" †¦ three out of four arrestees tested positive for at least one drug (including alcohol)† (p. 18). The median in this study describes the midpoint of the range where half of the data contained in the range falls

Soldier's home Essay Example | Topics and Well Written Essays - 750 words

Soldier's home - Essay Example t at social gatherings, "he fell into the easy pose of the old soldier among other soldiers: that he had been badly, sickeningly frightened all the time." (Hemingway 153). Unlike, ordinary peoples conception of home as a secure and safe haven, Krebs home is a soldiers home where he is always on the alert for the unexpected; he is frightened all the time; and he has learned to not to believe in anything. His lifes associations are not the beautiful girls, belief in God, honor, work, friendship or love for ones family. Instead, he believed in these elements as instruments to survival and diversions. In the picture of himself with a corporal and two German girls for instance, indicates that they have been acquaintances who had passed sometimes with him but do not have any significant meanings. Krebs disillusionment of his hometown and people stems from his post at Belleau Wood, Soissons, the Shampagne, St. Mihiel and the Argonne, where the battles had been the most fierce and bloody. These battles have had a deep impact on Krebs yet he is reluctant to talk about them. This is partly because people in Kansas already "had heard too many atrocity stories to be thrilled by actualities" and partly because these experiences have more value to him than his audience. He has found lying to make himself heard by his hometown too demeaning, and hence have been unwilling to degrade his memory and experience of war. Instead, Krebs has assumed a secluded lifestyle so that he does not have to encounter such situations when he had to lie about his war experiences. He avoids active socialization with the community whether through work or interaction with women. He finds that to get involved in any of these socialization processes, he would have to lie and lying is too complicated for him. He feels that untruth and exaggeration would eradicate his memory of the war, which is his actual reality. For him his hometown and its people are the enchantment which he had taken to the war and

Time and Memories Essay Example for Free

Time and Memories Essay Gwen Harwood’s poetry has provided me and hopefully you with some great wisdom and insight into our lives. Today I will be making meaning from the texts â€Å"At Mornington† and â€Å"The Violets† by Gwen Harwood. I am here, as a seventeen year old student, giving my own response through the analysis of the themes â€Å"Memory† and â€Å"Childhood to Adulthood†, the techniques which support them and through the application of psychoanalytical readings to her poetry. What we will see is that there are links present in what the composer is trying to say and in the critical interpretations of her poetry. Memories make the individual understand who they are, wouldn’t you agree? Without them we would just be robots. For example, just this morning I remembered a childhood memory of India. I remembered that everyday I would try and reach the light switch which always seemed so far away. Before I knew it, I could turn the light on and off with ease. It was only this memory that allowed me to reflect that from as young as a child I had been trying to reach things much higher than me. Who here could imagine not having any memories of their childhood? In the poem â€Å"At Mornington† by Gwen Harwood the fragility and nature of memories is questioned while it is concluded that it is through memories that one can accept death. The composer often uses the structure of her poetry to create meaning. For example, â€Å"At Mornington† is completely written in free verse, which means the composer’s thought process is allowed to be flexible supporting how memories suddenly come about. Let’s face it; memories do not exactly follow a rule†¦ They just come, sometimes with or without a trigger. This is exactly the case in â€Å"At Mornington† where the composer is left with an unexpected spark of memory while she stands with her friend on the parents’ grave. The composer describes this spark through a simile comparing this behaviour of memories with ‘light in a sea-wet shell’. The ‘light’ in the ‘sea-wet shell’ refers to the numerous colours produced when the light is focused on a common sea-shell. This to me means the childhood memories that we suddenly come across are diverse and in a way colour our lives. The most important message in this poem is the finality of death, and the role memories play in accepting it. The composer thinks of death ‘no more’ when she thinks of her father and more so the time spent with her friend. I can see the time with her friend metaphorically meaning the ‘peace’ of this day. This is the ultimate ‘peace’ for the composer as she approaches that inevitable death. I know you do not want to think of death right now but it is inevitable, and it is always assuring if memories are on our side. When I am older and nearing death, I can cling onto that nostalgic memory of reaching higher to reach the switch, and I can even tell my kids about it. There are many ways poems can be interpreted, there is my personal view but there are also other macro views. There is the Christian viewpoint that would argue that the memories of her father refer to God, and it is the memories of him that allow the composer to confront death because fathers as we know are a source of comfort, and in this case the fathers represent the ultimate father: God. However I do not have a strong Christian background, and I would rather see things through a psychoanalytical approach. In addition, I believe a psychoanalytical perspective applies better to the themes of Harwood’s poetry as the psych and its effect on the persona is explored. A psychoanalytical perspective would argue that memories are used to come to terms with the present psychological state. For example, the memories of her friend and of her father impact her to think of death ‘no more’. More so, light imagery is recurringly used to represent memories. For example the light refracting on the shell can be seen as a representation of the vivid and enthralling memories the persona experiences. This theme of â€Å"Memory† is similarly explored in the â€Å"The Violets† where a past memory helps support the present action which is of picking violets. Just like in â€Å"At Mornington† structure is used to create meaning. Memories are separated from present experience through indentation. This allows me to clearly distinguish between the persona’s present and the persona’s memories which actively support the present. There are some truly great memories that will influence us forever. For example, as I do my HSC I keep referring back to the memories of us in India and how hard my parents worked to get us to Australia. This is the sort of memory experienced by the persona, and she also explores how these memories or ‘lamplit presences’ will never die, even as time passes. These ‘lamplit presences’ are listed to the responder through the use of punctuation, notably the colon. The colon creates pause for the responder and this pause prepares us for the final comforting memories. Furthermore ‘years cannot move’ these final memories. If you stop and think about it aren’t those important memories everlasting? In the poem violet flowers are repeatedly mentioned from the title to the end where a ‘faint scent of violets drifts in the air’. What meaning can be made from this? Well, these violet flowers symbolise remembrance and the past, which is what the whole poem is about. As she thinks about the present, where the mood is somewhat ‘melancholy’ she nostalgically remembers a past event that ultimately contrasts the present joyless mood leaving a scent of violets which are associated with memories in the air. Enough of my view of things lets explore what how this can be seen psychoanalytically! The most important aspect to be mentioned is the use of memory to support the present. This is similar to â€Å"At Mornington† where memories of the past can be seen to impact the present but the only difference is that in â€Å"The Violets† it is more that memories have helped her deal with the present issue of time. In addition, light is used again as a symbol to represent memories. In this case it is the image of the lamp in ‘lamplit’ just like the refracted light referenced to memories in â€Å"At Mornington†. Remember when we were playful children? It was the free time of our lives, not chained down by assignments or by the commitments at work. But as we age we somewhat lose that playful phase and enter one of maturity where careers, education and most importantly future of life comes into light. The composer talks about â€Å"At Mornington† how as a child there is the notion of invincibility and naivety but as an adult there is the realisation of death. ‘I could walk on water’ is what the child persona thinks, and I knew we thought like that too. I remember thinking as a child that I could be like Superman. The use of personal pronoun ‘I’ is used to create meaning. How might you ask? Well, I think it creates a personal voice in the poem and illustrates to the responder that is her experience of childhood she is talking about. The persona reflects this childhood memory when she is an adult ‘while we [they] stand, two friends of middle age’. I can see that structure is used here significantly as the use of first person ‘we’ draws all of the audience in to think about growing up, to middle age. Can you image what we will be like when we are at middle age? I think we will have changed dramatically. This is the case here as the composer juxtaposes the childhood notions of life with the present notion where they are beginning to age. What I can say here is that as children we would think of many things, for example I would think I could fly, but as we change from children to adults we begin to see things differently and sometimes notice the change. Now I have gravity and aerodynamics as a young adult in my head, sharply changing my ideas about my aspirations of superman. The persona in â€Å"At Mornington† feels invincible as a child but this is changed when she is reflecting as a middle aged adult. Again a Christian reading could be applied to this poem where the child walking on water is an allusion to Jesus further highlighting the composer’s faith. But that is as far I can go; my personal context limits me from exploring any further. Therefore we could see it psychoanalytically where childhood to adulthood demands for the psyche to change. For example as a child she sees herself as invincible but as an adult she is made to adjust her psyche so death is accepted. A psychoanalytic reading would also see the child walking on water as a move from childhood to adulthood because as she walks on water her life and psyche of naivety progresses to maturity and of self realisation. The theme of â€Å"Childhood to Adulthood† is also explored in â€Å"The Violets†. It is an autobiographical poem, which deals with the persona’s view of various aspects as a child and as an adult. This is very similar to â€Å"At Mornington† where the persona reflects how childhood notions have changed as she has matured into an adult. However, in â€Å"The Violets† it is more a contrast of how she used to see things such as the flowers as a child and how she sees them later as an adult. It is probably the toughest transitions in life, from a child to an adult don’t you think? Understanding of the world is refined and childlike views of the world are replaced with the truth. The truth is often complex, and sometimes I wish I could just think like a kid again. This is demonstrated in a paradox used by Harwood. As an adult ‘melancholy’ flowers grow in ‘ashes and loam’. ‘Ashes’ refers to dead or the bad soil, infertile whereas ‘loam’ is the soil full of life. How can this flower grow in both? It tells me that as an adult things are much more complex and an essential way of looking at things has been lost. This is contrasted when the composer introduces us to a memory of childhood. The violets are in their ‘loamy’ bed, and it suggests that as a child they could be seen as simply flowers of spring and a source of comfort. Furthermore as an adult the word ‘melancholy’ is used to describe the atmosphere and it is again different to the mood created as a child of happiness. The mother laughs at the child persona as she questions about breakfast in the afternoon. ‘Laughing’ connotes a positive mood, reiterating the fact that childhood was a much happier time than adulthood. Who wouldn’t want to go back to their childhood days and play all day and live the simple life? Punctuation is structurally left out in ‘Ambiguous light. Ambiguous sky’ which to me emphasises the uncertainty in adulthood. Without the full stop the sentence is not complete and demonstrates that as an adult not even the night and day cannot be distinguished. A psychoanalytical reading would see this melancholy experience of the adult as longing for the experiences of a child. As a child the experience is the complete opposite, it is of happiness, and it is that experience that the composer finally gets, when remembering her childhood. Also the adult gains understanding about some uncertainty through a childhood experience. The positive memory of the mother laughing in the composer’s childhood also allows acceptance to occur. That laughing supported the uncertainty she had as a child and even the present uncertainty about adulthood. I think children’s thoughts are the most flawless in the world no matter how wise one gets Just by making meaning from two of Gwen Harwood’s poems â€Å"At Mornington† and â€Å"The Violets† I have received immense personal knowledge that I will never forget. I came see that â€Å"Memory† is a wonderful thing, and without it we would be nothing but some senseless dummies. I and hopefully you see that â€Å"Memory† in both the poems has the power to influence, impact and appease the present. This is the same with the discussion of â€Å"Childhood to Adulthood† where I was certainly reminded of my childhood days when I read the poem. Childhood gives us great views, but they are taken as we grow older such as I faced that I cannot be superman. Memories and our Childhood will always stay with us, and I thank Gwen Harwood for making me realise that. We must remember what she told us about life – it is‘only a matter of balance’.

The Salton Sea Essay -- Geography

The Salton Sea Introduction The Salton Basin , a below-sea-level depression which extends on the north from Palm Springs , California, to the Gulf of California , in the south. The Salton Sea has undergone historic cycles of filling with water and later drying up. The most recent predecessor to the Sea, that being Lake Cahuilla , last filled this area between 300 to 500 years ago and at one time had a surface elevation above sea level. In 1905 the flooding of the Colorado River was accidentally diverted into the Salton though and thus the Salton Sea was born. When the Colorado River floods retreated in 1907, the surface elevation of the Salton Sea slowly began to drop until the 1930ï ¿ ½s when agricultural drainage from the Imperial and Coachella Valleys sustained its level. Soon after , this Sea was turned into a state recreation area, wildlife refuge and a sport fishery. To this day, agricultural drainage and run-off is the major source of water inflow to the Salton Sea. When it was Healthy When the Sea was healthy it, drew recreationists from all around and was a popular sport fishing site. The marine level of salinity made it a great place to race boats and allowed for the introduction of salt water marine life. With all this attention the north side shore line soon became the Salton Sea State Recreation Area . Not only was this area attractive to people , but it was soon populated by birds and turned into a critical link for flocks of migratory birds along the Pacific Flyway. As a result , the Salton Sea National Wildlife Refuge was established on the south end of the Sea in the 1950ï ¿ ½s.(The Salton Sea Authority and the Bureau of Reclamation , 1997) Current Conditions Today the Salton Sea contains 7.3... ...tm 4.

My Name Is Asher Lev

Name: Waleed Khokhar Date: 11/13/12 Word Count: appx 900 Which character intrigues you the most? The protagonist and narrator of the book, â€Å"My name is Asher Lev† Asher Lev’s story begins with him as a young boy from a Jewish family. A young boy who lived in conservative community that was strict and fascist in nature when it comes to religion. Two conflicting forces play an important role in Asher Lev’s story. One, Asher Lev’s up tight and all- encompassing religious community, and the other his intense passion and desire to create art.Throughout Asher Lev’s life as a young child and as an adult, he had to trade-off between his love of creating art and/or following his family and community religious traditions. How Asher grows up with such intense friction in his mind of these two subjects is something important to elucidate. The decisions he made and the actions he took shaped his future. Asher grew up in an old-fashioned Jewish community of L adover; a community filled with narrow-minded people who did not want to look at the world beyond their realms. Due to this, Asher Lev was always in conflict with himself, his family and the community.As Aryeh, Asher Lev’s father said, â€Å"If you were a genius in mathematics, I would understand. If you were a genius in writing, I would also understand. If you were a genius in Gemorra, I would certainly understand. However, a genius in drawing is foolishness, and I will not let it interfere with our lives. Do you understand me, Asher? † (pg. 136). Asher’s father always condemned his work and wanted him to give up art. However, art surrounded and reflected in every part of Asher’s life. It is interesting to see even under immense pressure of his father Asher continued to draw.Usually, kids become rebellious if restricted. In this case, Asher just suppressed his feelings and confined to himself. Asher’s personality is the most mesmerizing in this bo ok. Living in a strictly religious family as boy and continually opposed by several people on creating art, Asher still managed to pursue his passion. It was a marvel in its own. Nonetheless, these two aspects of life balance out each other and play the most apprehensive part in his life. Asher’s creativity is one of the reasons he was able to continue with his work.One can see this when Asher uses common life material and create tools to paint (citation required). It is obvious that Asher possessed the gift of drawing.. Another aspect one needs to look at is Asher’s desperation and his urge to find such creative ways to express him in form of art. He was burning with desire to express his emotions by drawing. On one occasion, his strong influences lead him to steal paints from a shop. However, ethics and morals from his family teachings embedded in him evoked his conscience, and he eventually returned them.Such endeavors, at such a young age, living in such ascetic so ciety requires a lot of guts. It brings the crisp and twist in a story and binds a reader to discover of what lies ahead. In addition, it is hard to ignore how a young child with such creativity uses such ingenious ways to pursue his passion as Asher uses ashes to paint. It reminds me of a famous idiom ‘necessity is the mother of invention’. In the beginning, Asher did not understand his cravings as a child and innocuously doodled which turned into structured drawing later in his life.Furthermore, an on-going friction permeated inside Asher. He was confused with what was allowed to draw and what was deemed intolerable in his community. This is most evident when Asher’s father would not come to Asher’s art exhibitions, which displayed nude and crucifixion pictures. Asher justified such painting by saying (Book 11, pg. 303), â€Å"A naked women is a women without clothes. A nude is an artist's personal vision of a body without clothes. † â€Å"Is suc h a personal vision important in your art? † â€Å"That's what art is, Papa.It's a person's private vision expressed in aesthetic. † This brings Asher in the contradiction to his upbringing, what his beliefs were and what the world of art wants. It is astonishing for a reader of how Asher well aware that his father reproved nude paintings and yet without hesitation he invites his father. An analysis to this could be that Asher was so lost in the hymn of his passion that his childhood values were fading away. Whether these values would instill in Asher is something that intrigues a reader to continue with the story.Additionally, Asher’s interaction with an artist named Jacob Kahn, who immensely drew Asher towards new dimensions of art played the most significant role in this story. Asher learns different styles of painting and hones his skills under Kahn’s mentorship. Working with Kahn once again Asher faces the dilemma of whether to follow his religious te achings or follow the eccentric ways of world of art. Kahn played a pivotal role in Asher’s life and persuaded him to draw nude and crucifixion pictures, which were against Asher’s religion, Asher hesitant but open to learn suppressed his feelings and drew.Here once again, Asher prioritized art over his family and religion. In contrast, it is evident that Asher has not completely strayed away from his religious teaching as he continued to observe his Jewish dietary laws when he was away at Kahn’s beach house. Likewise, Asher leaves the reader tangled that whether he would lean back to his childhood education or ensue the world of art. Finally, the most controversial side of Asher becomes flamboyant when he drew his mother’s picture in form of crucifixion and invited his parents to his exhibition.Asher was well aware that his painting would bring great pain to his family and his community as crucifixion in Judaism is a taboo. Asher knowing the consequences will be dire yet he prioritized artistic world over Jewish world. From Asher’s point of view, this drawing only portrayed his emotions and it was targeted toward world of art where it carries a different meaning and only artists understand its value, whereas, Jewish community was naive of language of paint. Asher motive to invite his parents to gallery is questionable.A concern that arises is why Asher would invite his family to his exhibition. Did he deliberately want to inflict pain to his family and finally part away or was it another episode of innocence. The most bewildering scenes of this book which must have left several readers confused was in the ending chapter of the book where Asher stood thinking about his decisions in his life. Asher had to decide whether he wanted himself or religion; himself or family; and/or himself or art.Similarly, the writer has portrayed Asher’s uncanny nature and it leaves many questions in a readers mind. The book concludes in ma ny ways unresolved, as Asher was not fully comfortable with the decisions he had made. My Name is Asher Lev ends with protagonist banished from his people as Rebbe asked him to leave. So far, there are no means to conclude that Asher had embarked himself away from his family and community. No conclusive or unanimous consensus about Asher’s future choices

Price Matter At Customers Drugs And Treatment For...

Prices matter to customers. Donna Scrivens*, a 39-year-old deli owner living with Multiple Sclerosis, knows this as well as anyone does. Last August, when Scrivens was forced to raise prices on her ever-popular breakfast egg sandwiches, customers turned to alternatives. â€Å"Even some of the regulars stopped coming. People notice, and they have other options.† So why isn’t this also true for big pharma? As a consultant to pharmaceutical companies for three years, I talked to people afflicted with disease – like Donna – about affordability of their treatments. For some of the newest treatments on the market, drug prices, and subsequently patient costs, have reached unsustainably high levels. There is no denying that drug development has improved the lives of patients. â€Å"Rational drug design†, the process of developing medications based on the identification of a specific biological target, has produced promising new medications. For instance, Gleevec (imatinib) is a treatment for Chronic Myelogenous Leukemia (CML). In contrast to many chemotherapy agents which have a relatively non-specific impact on rapidly-dividing cancer cell and on the body’s healthy cells, Gleevec targets the disease itself. Drugs like Gleevec have significantly prolonged the lives of patients afflicted with diseases once thought to be deadly and incurable. But a drug is useless if people can’t afford it. Particularly in the last ten years, representatives of the pharmaceutical industry have provided a
