Persepolis Review â€Å"One can forgive but one should never forget† is one of the quotes that Marjane Satrapi says in her memoir titled Persepolis. The memoir tells the story of Marjane when she was ten years old during the Islamic Revolution in the Middle East, specifically in her home country Iran. Most people evacuated the country because they knew there was not going to be a safe, prosperous future for their children. Due to Marji’s development from youth to maturity, she undergoes teenage rebellion and feels a desire to escape. The entirety of this memoir is portrayed as a graphic novel where Satrapi uses illustrative techniques such as the way she shades and colors and also the way that some panels bleed for emphasis. Marji was a child†¦show more content†¦Furthermore, Marji was not only a girl when the war started, but she was a girl who was a bit of a rebel. Marji skipped school because she wanted to act mature, also because she didn’t want to feel isolated so she chose some 14 year-old friends. She followed them at Jordan Avenue to get some hamburgers but actually her friends went there to see some guys. In addition, Marji was expelled for many reasons. One of the reasons was because Marji hit the principal accidently when she was trying to get her wrists away. She was back talking the principal because of the jewelry policy and then accidently hit her which resulted in expulsion. Marji’s temperament was fiery when it came to something she was passionate about and cared about deeply. Additionally, Marji had been in Iran for the past 12 years of her life and she noticed that Iran will never be the same. She wanted to leave the country with her family but not everything went as planned. Marji was not the only person who wanted to leave Iran, in the memoir she says, â€Å"After my friend’s departure, a good part of my family also left the country. ‘Maybe we should leave too†¦Ã¢â‚¬â„¢ said Taji. ‘So that I can become a taxi driver and you a cleaning lady?’ Ebi (Marji’s father). ‘My friend Kaveh left for the United States too.’ Marji said sadly. ‘Don’t worry.

Dividend Policy Free Essays

Dividend Policy Vinod Kothari Corporations earn profits – they do not distribute all of it. Part of profit is ploughed back or held back as retained earnings. Part of the profit gets distributed to the shareholders. We will write a custom essay sample on Dividend Policy or any similar topic only for you Order Now The part that is distributed is the dividend. The ratio of the actual distribution or dividend, and the total distributable profits, is called dividend payout ratio. How much of its profits should a corporation distribute? There are several considerations that apply in answering this question. Hence, companies have to frame and work on a definitive policy of dividend payout ratio. Of course, no corporate management can afford to stick to a fixed dividend payout ratio year after year – neither is such fixity of dividend payout ratio required or expected. However, management has to broadly decide its policy on its broad attitude towards distribution – liberal dividend payout ratio, or conservative dividend payout ratio, etc. If one were to ask this question in context of debt sources of capital – for example, how much interest should a corporation pay to its bankers, the answer is straight forward. As interest paid is the cost of the borrowing, the lesser the interest a corporation pays, the better it is. Besides, companies do not have choice on paying of interest to lenders – as the rate of interest is contractually fixed. Rate of dividends may be fixed in case of preference shares too. However, in case of equity shares, there is no fixed rate of dividends. It cannot be said that the dividend paid is the cost of equity capital – if that was the case, corporations may try to minimize the dividend distribution. Hence, the following points emerge as regards the dividend distribution policy: †¢ The cost of equity is defined as the rate at which the corporation must earn on its equity to keep the market price of the equity shares constant. Let us further suppose that the market price of the shares is obtained by capitalizing the earnings of the corporation at a certain capitalization rate – the capitalization rate itself depending on the riskiness or beta of the industry. Suppose the corporation does not earn any profit. Shareholders were expecting a certain rate of return on their shareholding – hence, share prices will fall at the expected return on equity. On the other hand, if just the expected rate of return is earned by the corporation, the price of equity shares remains constant if the earnings are entirely distributed, and xactly grows by the expected rate of return if the earnings are entirely retained. The above discussion leads to the conclusion that the cost of equity is not the dividends but the return on equity – hence, a corporation cannot work on the objective of minimizing dividends. Equity shareholders are the owners of the corporation – hence, retained earnings ultimately belong to the shareholders. Supposing a company earns return on equity of 10%, and retains the whole of it, the retained earnings increase the net asset value (NAV) of the equity shares exactly at the rate of 10%. Assuming there are no other factors affecting the equity price of the company, the market price of †¢ †¢ †¢ †¢ †¢ †¢ the shares should exactly go up by 10% commensurate with the increase in the NAV of the shares. That is to say, shareholders gain by way of appreciation in market price to the extent of 10%. On the other hand, if the company distributes the entire earnings, shareholders earn a cash return of 10%, and there is no impact on the NAV of the shares, hence, the same should remain unchanged. Therefore, in both the cases, the shareholders earned a return of 10% – in the first case, by way of growth or capital appreciation, and in the second case, by way of income. In other words, merely because the corporation is not distributing profits does not mean it is depriving shareholders of the rate of return on equity. The above two points reflect the indifference, sometimes referred to as irrelevance of dividend policy (see Modigliani and Miller approach later in this Chapter) from the viewpoint of either the company or its shareholders. Supposing the corporation decides to retain the entire earning. Obviously, the corporation would earn on this retained profit at the applicable return on equity. Note that the return on equity is relevant, as retained earnings would be leveraged and would, therefore, benefit from the impact of leverage too. On the other hand, if the corporation were to distribute the entire profits, shareholders reinvest/consume the income so distributed at their own rate of return. Hence, it may be contended that whether the company retains or distributes the earnings depends on whose reinvestment rate is higher – that of the company or that of the shareholders? Quite clearly, the rate of reinvestment in the hands of the corporation is higher than that in the hands of the shareholders, (a) because of leverage which shareholders may not be able to garner; and (b) intuitively, that is the very reason for the shareholders to invest in the company in the first place. This argument generally favors retention of profits by the company rather than distribution. [As we discuss later, this argument is the basis of the Walter formula] As a counter argument to this, it is contended that shareholders do not need growth only – they need current income too. Many investors may sustain their livelihood on dividend earnings. Of what avail is the increase in market value of shares, if I need cash to spend for my expenses? However, in the age of demat securities and liquid stock markets, growth and income are almost equivalent. For example, if I am holding equity shares worth $ 100, which appreciate in value to $ 110 due to retention, I can dispose off 10/110% of my shareholding, earn cash equal to $ 10, and still be left with stock worth $ 100, which is exactly the same as earning cash dividend of $ 10 with no retention at all. While the above argument may point to indifference between growth and income, the reality of the marketplace is that investors do have varying preferences for growth and income. There are investors who are growth-inclined, and there are those who are income-inclined. Majority of retail investors insist on balance between growth and income, as they do not see an exact equivalence between appreciation in market value and current cashflows. Hence, the conclusion that emerges is that companies do have to strike a balance between shareholders’ need for current income, and growth opportunities by retained earnings. Hence, dividend policy still remains an important consideration. While making the above points, there are certain special points that affect particular situation that need to be borne in mind: †¢ Company’s reinvestment rate lower than that of shareholders: Sometimes, there are companies that do not have significant reinvestment opportunities. More precisely, we say the reinvestment rate of the company is lesser than the reinvestment rate of shareholders. In such cases, obviously, it is better to pay earnings out than to retain them. As the classic theories of impact of dividends on market value of a share (see Walter’s formula below) suggest, or what is anyway intuitively understandable, retention of earnings makes sense only where the reinvestment rate of the company is higher than that of shareholders. †¢ Tax disparities between current dividends and growth: In our discussion on indifference between current dividends and share price appreciation, we have assumed that taxes do not play a spoilsport. In fact, quite often, they do. For example, if a company distributes dividends, the same may be taxed (either as income in the hands of shareholders, or by way of tax on distribution – like dividend distribution tax in India). Alternatively, if the shareholders have a capital appreciation, which they encash by partial liquidation of holdings, shareholders have a capital gain. Taxability of a capital gain may not be the same as that of dividends. Hence, taxes may differentiate between current dividends and share price appreciation. Shares with fixed returns: Needless to say, there is no relevance of dividend policy where dividends are payable as per terms of issue – for example, in case of preference shares. †¢ Entities requiring minimum distribution: There might also be situations where entities are required to do a minimum distribution under regulations. For example, in case of real estate investment trusts, a certain minimum distribution is required to attain tax transparent status. There migh t be other regulations or regulatory motivations for companies to distribute their profits. These regulations may impact our discussion on relevance of dividend policy on price of equity shares. †¢ Unlisted companies: Finally, one must also note that discussion above on the parity between distributed earnings and retained earnings – the latter leading to market price appreciation – will have relevance only in case of listed firms. Technically speaking, in case of unlisted firms too, retained earnings belong to the shareholders, as shareholders after all are the owners of the residual wealth of the company. However, that residual ownership may be a myth as companies do not istribute assets except in event of winding, and winding up is a rarity. The discussion in this chapter on dividend policy, as far is relates to market price of equity shares, is keeping in mind listed firms. In case of unlisted firms, classical models such as Walter’s model or Gordon Growth model discussed below may hold relevance than market price-based models. From dividends to market value of equity: Dividend capitalisation approach: If, for a second, we were to ignore the stock market capitalisation of a company, what is the market value of an equity share? Say, we take the case of an unlisted company. We know from our discussion on present values that the value of any asset is the value of its cashflows. What is the cashflow a shareholder gets from his equity? As long as the company is not wound up, and the shareholder does not sell the stock, the only cashflow of the shareholder is the dividends he gets. It is easy to understand that if we are not envisaging either a sale of the shares or a liquidation of the company, then the stream of dividends may be assumed to continue in perpetuity. Hence, VE = ? ? (1 + K i =1 Di E )i (1) Where VE : Value of equity K E : Cost of equity Di : dividends in paid in year i Equation (1) is easy to understand. Shareholders continue to receive dividends year after year, and these dividends are discounted by the shareholders at the cost of equity, that is, the required return of the shareholders. If the stream of dividends is constant, then Equation (1) is actually a geometric progression. We can manipulate Equation (1) either to compute the price of equity, if the constant stream of dividends is known, or to compute the cost of equity, if the dividend rate and market price of the shares is known. Applying the geographical progression formula for adding up perpetual progressions, assuming constant dividends equal to D, Equation (1) above becomes: VE = = D (1 + K E ) ? (1 ? 1 ) 1+ KE (2) D KE Example: Supposing a company the nominal value equity were $ 100, and the dividends at the rate of 10 % were $ 10, if the cost of equity is 8%, then the market price of the shares will given by 10/8%, or $ 125. Incorporating growth in dividends: In our over-simplified example above, we have taken dividends to be constant. It would be unusual to expect that dividends will be constant, particularly where the company is not distributing all its earnings. That is to say, with the retained earnings, the company has increasing profits in successive years, and therefore, it continues to distribute more. If dividends grow at a certain compounded rate, say g, then, Equation (2) above becomes: VE = D (1 + g ) (1 + K E ) = ? (1 ? 1+ g ) 1+ KE (3) D (1 + g ) KE ? g Note that we have assumed here that even the first dividend will have grown at g rate, that is, the historical dividend has been D, but we are expecting the current year’s dividend to have increased at the constant rate. If we assume the current year’s dividend will not show the growth, and the growth will come from the forthcoming year, then we can remove (1+g) in the numerator above. The formula as it stands is also referred as Gordon’s dividend growth formula, discussed below. Example: Supposing a company the nominal value equity were $ 100, and the dividends at the rate of 10 % were historically $10. Going forward, we expect that the dividends will continue to grow at a rate of 5% per annum. If the cost of equity is 8%, what is the market value? We put the numbers in the formula and get a value of $350. Note that we can also test the valuation above on Excel. If we take sufficient number of dividends, say, 1000, successively growing at the rate of 5%, and we discount the entire stream at 8%, we will get the same value. Example: Supposing a company the nominal value equity were $ 100, and the dividends at the rate of 10 % were historically $10. Going forward, we expect that the dividends will continue to grow at a rate of 12% per annum. If the cost of equity is 8%, what is the market value? This is a case where the growth in dividends is higher than the discounting rate. The growth in dividends is a multiplier; the discounting rate is a divisor. If the multiplier is higher than the divisor, then the present value of each successive dividend will be higher than the previous one, and hence a perpetual series will have infinite value. There is yet another notable point – the growth rate g above may be also be visualised as the appreciation in the market value of the share. That is, shareholders are rewarded in form of current earnings as well as growth in the value of their investment. Dividend-based equity models: Walter Approach: The Walter formula belongs to James E Walter, and is based on a simple argument that where the reinvestment rate, that is, rate of return that the company may earn on retained earnings, is higher than cost of equity (which, as we have discussed before, the expected returns of the shareholders, or rate of return of the shareholders), then, it would be in the interest of the firm to retain the earnings. If the company’s reinvestment rate on retained earnings is the less than shareholders’ rate of return, the company should not retain earnings. If the two rates are the same, then the company should be indifferent between retaining and distributing. The Walter formula is based on a simple analysis that the market value of equity is the capitalisation of the current earnings and growth in price (g in our formula in equation 3 above). Hence, the basis of Walter formula is: VE = D +g KE (4) Here, the growth factor occurs because the rate of return on retention done by the company is higher than the cost of equity. That is to say, the company continues to earn at r rate of return on the retained earnings, and this is what causes growth g. Hence, g= r (E-D)/ K E Inserting equations (5) into (4), we have VE = (5) D KE + r (E – D)/K E KE (6) Where r = rate of return on retained earnings of the company E = earnings rate D = dividend rate Example: Supposing a company the nominal value equity is $ 100, and the dividends at the rate of 10 % are $10. Supposing the company earns at the rate of 12% , what is the market value of equity if the the cost of equity is 8%? The market value of the share comes to $ 162. 50. This is explainable easily. As the company is earning $12, and distributing $10, it retains $ 2 every year, on which it earns at 12%. The capitalised value of 0. 24 at 8% will be the expected growth. Therefore, the sustainable earnings of the shareholders will be $ 10 +3, which, when capitalised at 8%, produces the value $ 162. 50. Of course, the key learning from Walter’s approach is not what the market value of equity is, but how the market value of equity can be maximised by following a proper distribution policy. For instance, in the present case, it is not advisable for the company to distribute any dividend at all, as the company earns more than the shareholders’ opportunity rate. If the company was not to distribute anything, the market value of the share may increase to $ 225. Gordon growth model: Gordon’s growth model is simply Equation (3) above, that is, VE = D (1 + g ) KE ? g This is, as we have seen above, derived from perpetual sum of a geometric progression, under the assumption that the growth rate is less than the cost of equity. Modigliani and Miller approach: Franco Modigliani was awarded Nobel prize in 1985 and Merton Miller in 1990 (along with Markowitz and Sharpe). MM have theorised on the irrelevance of the capital structure, and a corollary, irrelevance of the dividend payout ratio to the value of the firm. Like several financial theories, MM hypothesis is based on the argument of efficient capital markets. In addition, we believe that a firm has two options: (a) It retains earnings and finances its new investment plans with such retained earnings; (b) It distributes dividends, and finances its new investment plans by issuing new shares. The intuitive background of the MM approach is extremely simple, and in fact, almost selfexplanatory. It is based on the following propositions: †¢ Why would a company retain earnings? Only tenable reason is that the company has investment opportunities. If the company does not retain earnings, where does it finance those investment opportunities from? We may assume a debt issuance, but then as MM otherwise propounded irrelevance of the capital structure, they see a parity between debt and equity, and hence, it does not make a difference whether the new investments are funded by equity or debt. So, let us assume that the new growth plans are funded by equity. Shareholders price the equity shares of the company to take into account the earnings and the retentions of the company. If the company distributes dividends, the shareholders take into account that fact in pricing of the shares; if the company does not distribute dividends, that is also reflected in the pricing of the shares. If dividends are distributed, the financing needs of the company will be funded by issuing new shares. The issue price of these shares will compensate for the fact that the dividends have been distributed. That is to say, the market price of the share will remain unaffected by whether the dividends have been distributed or not. †¢ †¢ Let us take a one year time horizon to understand the indifference argument of MM. We use the following new notations: Po P1 D1 n m I X : Price of the equity share at point 0 : Price of the equity share at point 1, that is, end of period 1 : Dividend per share being paid in period 1 : existing number of issued shares : new shares to be issued : Investment needs of the company in year 1 : Profits of the firm year in 1 The relation between the price at the beginning of the year (Po), and that at he end of the year (P1) is the simple question of discounted value at the shareholders’ expected rate of return (KE). Hence, Po = (P1 +D1) / (1+(KE) (7) Equation (7) is quite easy to understand. Shareholders have got a cash return equal to D1 at the end of Year 1, and the share is still worth P1. Hence, discounted at the cost of equity, the discounte d value is the price at the beginning of the period. Alternatively, it may also be stated that the P1 = (P0 )* (1+(KE) – D1 (8) That is to say, if the company declares dividends, the price the end of year 1 comes down to the effect of the distribution. Equation (7) can be manipulated. By multiplying both sides by n, and adding a self-cancelling number m, we may write (7) as follows: nPo = [(n+m)P1 -mP1 +nD1)]/(1+(KE) (9) Note that we have multiplied both sides by n, and the added number m along with m is cancelled by deducting the same outside the brackets. mP1 represents the new share capital raised by the company to finance its investment needs. How much share capital would the company need to raise? Given the investment needs I and the profits X, the new capital issued will be given by the following: mP1 = I – (X – nD1) (10) Again, this is not difficult to understand, as the total amount of profit of the company is X, and the total amount distributed as dividends is nD1. Hence, the company is left with a funding gap as shown by equation (10). If the value of mP1 is substituted in Equation (9), we have the following: nPo = [(n+m)P1 – {I – (X – nD1)}+nD1)]/(1+(KE) (11) As nD1 would cancel out, we will be left with the following: nPo = [(n+m)P1 – I + X] /(1+(KE) (12) Since nPo is total value of the stock at point 0, it is seen from Equation (12) that dividend is not a factor in that valuation at all.

Presentation of the Gothic Male Protagonist Essay Example

Presentation of the Gothic Male Protagonist Essay To what extent does the characterization of Heathenish exemplify gothic elements? Emily Bronzes Withering Heights is not necessarily described as a gothic novel; however it certainly exhibits many gothic elements throughout its narrative. These are present through the characterization of Heathenish as the gothic protagonist as he often exemplifies numerous characteristics of the male gothic archetype. This can be seen through the exploration of binary oppositions within his character, such as his simultaneous representation as both victim and Machiavellian villain. This duality of character can be likened to the protagonist In The Strange Case of Dry Jewell and My Hyde, in which an alternate persona is created in order to fulfill Dry Jellys evil desires. Although Heathenish does not create a defined alternate personality, his drastic inner contradictions are reminiscent of Dry Jellys, shown through his capable for intense love towards Catherine, and simultaneous tyrannical treatment of Isabella. Another prevalent gothic aspect which Is significant to the characterization of Heathenish Is his current associations with bestial and preternatural Influences. Josephs assertion that weve all as summate uh rather side in us, introduces the idea of being connection with bestial or non-human influences, a recurrent theme in the characterization of male protagonists within gothic literature. His appearance is a physical manifestation of his separation from the Earns family, aligning his with the other, describing him as a dark skinned gypsy emphasizes his unknown parentage, marking him as an outsider.

Recurrent descriptions of him being dark creates ambiguity of whether this is a reference to his race or his nature, heightening the enigma surrounding Heathenish. Its so dark almost as if it came from the devil, through labeling him as it, the lack of nominal attribution disables him from ever truly being Integrated into the Earns family. Satanic connotations draw upon the gothic theme of the supernatural and connect him to these evil Influences, acting as warning of his potentially destructive powers. Shelter associations of his characterization are once again highlighted through the description of his basilisk eyes, suggesting bestial and mythical connections. This constructs Heathenish as being in possession of considerable powers, whilst the annalistic qualities depict a degree of other-worldliness. His continual connection with alternative influences further divides him from the Awareness: A lying fiend, a monster, and not a human being! This demonstration of Heathenish places him In a lamina sphere between human ND inhuman while monster reinforces his brutality, distancing him from empathy or humanity, reminding us of his status as other. Claire Jones stated Heathenish has only the singular name, which serves him as both Christian and surname. This places him radically outside social patterns and conventions. The implantation of the protagonist lends his character to the constant alignment with the enigmatic and unconventionality rather than being accepted by the Awareness: subsequently being An archetype of the gothic male is the possession of considerable powers to create n imposing stance; as stated by David Punter they often stalk the pages of the novel, adding to the subtle terror present within gothic literature. Throughout the narrative the striking physical appearance of Heathenish is communicated to the reader, an aspect constructed through his dominance. Even after death the protagonist holds a power over the remaining characters. Through using a dash close his eyes - Bronze creates a fragmented, breathless tone and we adopt Kneels fearful nature as we are forced to pause and reflect on Heathenishly threatening presence. Likewise as a consequence of her feeble attempts l tried, her fears are projected onto the reader as we adopt her perspective throughout due to her dominance in relaying the narrative. Her tentative nature If possible reinforces his striking physicality as Newly appears to be confronting a considerable force, this notion is emphasizes through continual reference to his life-like gaze which denotes a threatening presence. Meanwhile her doubtful tone is indicative of his ability to transcend the boundary between life and death as her contains passions which Anton be constrained in death. The preternatural nature of Heathenish is communicated through his physical description they would not shut. Through the use of his eyes as the focal point, a satanic, defiant power is suggested while his sharp, white teeth convey his tyrannical behavior through the annalistic connection. This can also be likened to a vampire descriptions which is reminiscent of Count Drachma from Stokers Drachma, thus creating a threatening tone through the linking of both protagonists as it suggests reverent behavior. Heathenishly physical ability is communicated a blow form Heathenish is significant as it is demonstrative of the ease with which he can inflict harm in a single blow. Binary oppositions are often utilized as a vehicle for portraying Heathenishly duality of character, a collective trait within gothic protagonists. A recurrent aspect of his characterization is the representation of him to the reader as both victim and villain. The description of his lip of devoid of their ferocious sneer exemplifies his manipulative nature and constructs his capability for savagery as constant and a defining trait within his harasser. As he is devoid of this malicious gaze, we glimpse a rare of his inner vulnerability. This is reiterated through his unspeakable sadness which outlines the contradictions which occur within the characterization of Heathenish. Despite this, we are unable to ever truly sympathies with the protagonist as any helplessness we are shown the stray sheep us immediately contradicted through the use of contrasting imagery an evil beast. This leaves the reader in a state of ambivalence towards Heathenish as his potential for evil is omnipresent, even in times of weakness.

Allegory of the cave essayEssay Writing Service Allegory of the cave essay Allegory of the cave essayMy perception of reality may and, in all probability, does differ from reality since the reality is a highly subjective issue, if perceived at the individual level. As I perceive the surrounding world or reality, I am still vulnerable to biases that affect my perception of reality. In the course of my personal development I have acquired some personal experience and shaped my basic values, views and beliefs which interfere into my perception of reality. As a   result, the reality may differ from the reality which I perceive subjectively.To eliminate biases and to make me perceiving reality as it is, I need to get rid of those biases and subjectivity which prevents me from accurate perception of reality. In this regard, the critical thinking of reality can help me to minimize the subjectivity of my perception. For instance, I can doubt in actually any issue which I can perceive in the surrounding world, such as the Sun going from the East to the West create s the impression of going around the Earth but, using critical thinking, I should admit the opposite idea and find out the truth through observations and experiments.However, I cannot apply such critical thinking every time I dealt with reality. My perception of reality remains subjective since I have to take many issues for granted. Otherwise, I would not have done a tenth of those activities, which I do on the regular basis. In this regard, my perception of reality also depends on mass media and my social environment since messages I receive from them affect my perception of reality too. Critical thinking and objective analysis are the main ways to break those bonds imposed on me by mass media and my social environment.

According to the article, Judge Amy Berman Jackson supported the wildlife service’s judgment while the federal official were â€Å"arbitrary and capricious† in accepting it (Wines, 2). In addition, the protection wolves’ act brings to light, through this article, that there is need to protect wolves. I learn that trophy hunters, who consider wolves as predators, shoot or trap these wolves. As a result, the Fish and Wildlife Service is proposing to end protection for wolves everywhere else apart from southern Arizona and New Mexico, where the Mexican wolf, is scarcely populated. In summary, the main relevance of this restoration is to urge the college students of New Mexico, to support all measures to keep wolves safe. Wines, Michael.

Analyzing Supply Chain Management and Innovation (WAL-MART) Essay

Analyzing Supply Chain Management and Innovation (WAL-MART) - Essay Example The success of Wal-Mart stores Inc. can be attributed to its ability to manage the supply chain efficiently. This essay analyzes the strategies that Wal-Mart uses for its supply chain management and innovation practices. Wal-Mart has a wide array of products targeting families and middle class individuals with modest incomes. Most of these customers are more focused on the quality of the products they purchase from Wal-Mart stores, rather than the branding of the products. There are four main elements of Wal-Mart’s supply chain management strategy. These are technology, vendor partnerships, integration, and cross docking and distribution management (Leeman, 36). The whole process starts from strategic sourcing, which is aimed at identifying high quality products at the best prices from reputable suppliers who have the ability to meet the existing demand. The organization then forms strategic partnerships with most of the vendors, creating a long term relationship that benefits the customers. The suppliers will then ship their products to the Wal-Mart stores for cross docking and delivery to stores in other locations around the world. The cross docking process, efficient management of distribution, and the transportation process helps Wal-Mart to maintain a constant inventory to cater for market demand. The company also focuses on eliminating inefficiencies that can undermine the whole process. Wal-Mart is highly regarded for its innovative business practices in the industry(Leeman, 69). For instance, it was among the first companies on the global scene to centralize their distribution system and rely heavily on Information Technology. Wal-Mart manages its Supply chain by using a highly integrated approach that brings together elements of logistics, operations management, information Technology, and procurement. The success of Wal-Mart’s strategy of

Depression, how would you work psychoanalytically with this diagnosis Essay

Depression, how would you work psychoanalytically with this diagnosis - Essay Example What art is to Pollack, studying is to me when it comes to demystifying an enigma. Thus, I am finally conquering my fears and writing about depression for this paper. In reading about it, I realized the many depressive stages in my life and bore resistance to understanding them. Now, it is clear to me that such resistance was due to not wanting to touch on the depressive condition and come face to face with my own depression. I know that studying in-depth and writing about this sensitive topic would be beneficial not only to my readers but also to me as a psychotherapist and as a flawed being in the dark who finally wants to see the light. This essay commences with the etiology of depression followed by some psychodynamic theories about it. It then presents a clinical example of a case study that is analyzed using the discussed theories. A reflective critique then follows as I give my own opinions and views about the use of psychoanalysis in the treatment of depression. Depression is associated with â€Å"feelings of extreme sadness† which not only last for long periods of time, but it is also recurrent and may further develop into suicidal tendencies (NHS, 2010). It is usually manifested with negative behaviors stemming from negative emotions. Sometimes, the person experiencing it is not even aware that he is undergoing depression. Its concept as a serious and debilitating illness, one which has had great impact globally, has become recognised within general medicine and the public eye in more recent times (NHS, 2010). Examples of symptoms which form the diagnostic criteria for depression include: depressed mood; fatigue or loss of energy and recurrent thoughts of death or suicide, which may be noticed in most circumstances through General Practitioners. In turn a diagnosis is generated following an interview of the patient with the application of

Biomedical instrumentation and measurement

Biomedical instrumentation and measurement INTRODUCTION: SA node controls the rate of hearts muscular contractions which enables the heart to circulate the blood throughout the body according to the need. Small variations in the heart beat are not harmful but in some cases due to malfunctioning of the hearts electrical system, the heart rate varies drastically resulting in different types of arrhythmias. These cardiac arrhythmias are serious disorders which should be treated immediately. Arrhythmias like bradycardia (low heart rate) can be treated using Pacemakers. Pacemakers can be implanted in the patients heart for permanently stimulating the heart. It is used for patients for whom the SA node is no longer functioning properly. External Pacemakers are also available which is used to treat temporary heart rate variations. It is used for a short period of time before the implanting the Internal Pacemakers in the heart. In order to understand the requirement of pacemakers, it is necessary to understand the functioning of the heart and its electrical system. HEART ITS ELECTRICAL SYSTEM: Heart is a pumping device which is used to circulate the blood throughout the body. It has four chambers namely Right Atrium, Left Atrium, Right Ventricle and Left Ventricle. The right atrium receives the deoxygenated blood from the entire body through the superior vena cava and inferior vena cava. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. When the atrium contracts the blood flows to the corresponding ventricle. This is due to atrial depolarization. When the left ventricle contracts, the oxygenated blood is supplied to all tissues in the body through the aorta. This is due to ventricular depolarization. Similarly, the deoxygenated blood is pumped to the lungs for oxygenation through the pulmonary artery during the contraction of right ventricle. This is due to ventricular repolarization. The Electrical conduction system of the heart consists of SA node, AV node, Bundle of His, Purkinje Fibers. The chambers of the heart should be stimulated electrically for contraction. The stimulations are provided by the SA node (Natural Pacemaker of the heart) which is located in the right atrium of the heart near the entrance of the superior vena cava. Although all the heart cells have the ability to produce electrical pulses which can stimulate the heart, SA node triggers the heart. The fact that SA node produces pulses at a higher rate when compared to other potential cells which can stimulate contraction, contributes to this phenomena. The contraction of various chambers of the heart is characterized in a very specific manner. As the electric pulses pass through each chamber of the heart, they are stimulated to contract. The SA node first triggers the right and left atrium to contract. Then the impulses travel to the AV node which is located between the atria and the ventricles . From AV node ,the pulses travel to the bundle of his. The pulses travel to the individual ventricles through the right and left bundle branch and reach the Purkinje fibers. If the SA node fails, then the AV node acts as the primary pacemaker. If the AV node fails, then the Purkinje fibers takes the responsibility. The SA node receives blood supply from right and left coronary arteries. Under ischaemic conditions, the death of the affected cells will stop the SA node from triggering the heart beat. There is a period of time following the stimulation of heart muscle during which no other action potential can trigger the heart muscles. This period is known as Absolute or Effective Refractory Period (ERP) of heart. It is normally around 0.4 sec. ERP is maintained as high as possible in order to maintain tachycardia and to coordinate the muscle contraction. The anti-arrhythmic drugs taken by the patients usually prolongs the ERP. ELECTRICAL SYSTEM OF HEART ECG ITS SIGNIFICANCE: The electrical activity of the heart muscles is recorded as Electrocardiogram (ECG). It can be acquired non-invasively from the surface of the body by following specific lead configurations. The electrical current generated in the heart due to depolarization and repolarization is spread not only within the heart but also throughout the body. So, ECG can be easily acquired from the surface of the body through electrodes. ECG has four basic components namely, P wave, QRS complex, T wave and U wave. P wave occurs during atrial contraction due to atrial depolarization. The duration of the P wave ranges from 0.08- 0.1 sec. During the atrial depolarization, the impulse from the SA node spreads throughout the atrium. The time period between the onset of the P wave and the beginning of the QRS complex is about 0.12- 0.2 sec. During the zero potential period between the P wave and QRS complex, the impulse travels within the AV node and the Bundle of His.QRS complex occurs during ventricular c ontraction due to ventricular depolarization. The duration of the QRS complex ranges from 0.06-0.1 sec. T wave occurs during ventricular relaxation due to ventricular repolarization. Sometimes, a small positive U wave occurs following the T wave due to the last remnants of the ventricular repolarization. ELECTROCARDIOGAM NORMAL AND ABNORMAL ECG WAVES: Normal ECG: NORMAL ECG Heart rateis nothing but the number ofheartbeatsper unit oftimewhich is expressed as beats per minute (bpm) which can vary as the bodys need for oxygen changes, such as duringexercise or sleep. The measurement of heart rate is used bymedical professionalsto assist in thediagnosisand tracking of medical conditions. It is also used by individuals, such asathletes, who are interested in monitoring their heart rate to gain maximum efficiency from their training. TheR waveto R wave interval(RR interval) is the inverse of the heart rate ,that is one divided by RR interval gives the heart rate. Typical healthy resting heart rate in adults is 60-80 bpm which is referred to be normal heart rate,with rates below 60 bpm referred to asbradycardia and rates above 100 bpm referred to astachycardia. Missed ECG: MISSED ECG This can be detected when the R-R interval is twice the actual R-R interval (for normal subjects).Heart pulses misses at some intervals and does not follow the premature heart beat. Bradychardia: BRADYCARDIA This is a critical reduction of heart rate and characterized by normally directed abnormally wide P waves and normal PR interval. Whenever the R-R interval exceeds 1 sec the heart rate goes below 60 and the condition is referred to as Bradychardia. There are three types of Bradychardia conditions based on the characteristics of the ECG wave, they are Sinus bradychardia, Atrio-ventricular nodal bradychardia and ventricular bradychardia respectively. They are discussed below. Sinus bradycardia: SINUS BRADYCARDIA Sinus bradycardias are also called as Atrial bradychardias. This bradychardia condition is usually found in young and healthy adults. The symptoms represent with the individualsrespirations. Theabnormalpattern of eachinhalationcorresponds with the heart rate decreasing.Expirationcauses an increase in the hearts rate of contraction. This is thought to be caused by changes in the vagal tone duringrespiration. Sinus bradycardia is a sinus rhythm of less than 60 bpm. It is a common condition found in both healthy individuals and those who are considered wellconditioned athletes. The reason for this is that their heart muscle has become conditioned to have a higher stroke volume and therefore requires fewer contractions to circulate the same volume of blood. Sick sinus syndromecovers conditions that include severe sinus bradycardia, sinoatrial block, sinus arrest, and bradycardi-tachycardia syndrome (atrial fibrillation, flutter, and paroxysmal supraventricular tachycardia). Atrio ventricular nodal bradycardia: ATRIO VENTRICULAR NODAL BRADYCARDIA An atrio ventricular nodal bradycardia or AV junction rhythm is usually caused by the absence of the electrical impulse from thesinus node. This usually appear on anEKGwith a normal QRS complexaccompanied with an inverted P wave either before, during, or after the QRS complex. An AV junctional escape is a delayed heartbeat originating from anectopicfocus somewhere in theAV junction. It occurs when the rate ofdepolarizationof the SA node falls below the rate of the AV node.This dysrhythmia also may occur when the electrical impulses from the SA node fail to reach the AV node because of SA or AV block.This is a protective mechanism for the heart, to compensate for a SA node that is no longer handling the pace making activity, and is one of a series of backup sites that can take over pacemaker function when the SA node fails to do so. This would present with a longerPR interval. A junctional escape complex is a normal response that may result from excessive vagal tone on the SA node. Pathological causes include sinus bradycardia, sinus arrest, sinus exit block, or AV block. Ventricular bradycardia: VENTRICULAR BRADYCARDIA This picture shows an ECG of a person with an abnormal rhythm (arrhythmia) called an atrioventricular (AV) block. P waves show that the top of the heart received electrical activity. Each P wave is usually followed by the tall (QRS) waves. QRS waves reflect the electrical activity that causes the heart to contract. When a P wave is present and not followed by a QRS wave (and heart contraction), there is an atrioventricular block, and a very slow pulse (bradycardia). PACEMAKER AND ITS SIGNIFICANCE: More than 60% people fall victim to heart attacks in most of the countries around the globe every year and thousands more are critically injured in accidents. Taking care of these patients in special care units involves the usage of specialized equipments like pacemakers along the other important ones. In the past few years electronic pacemaker systems have become the important one in saving lives of cardiac patients whose normal pacing functions have been impaired. Depending on the exact nature of a cardiac dysfunction, a patient may require temporary artificial pacing during the course of treatment or permanent pacing in order to lead an active, productive life after treatment. A device capable of generating artificial pacing impulses and delivering them to the heart is known as a pacemaker system (commonly called a pacemaker) and consists of a pulse generator and appropriate electrodes. Pacemakers are available in a variety of forms. They are mainly divided into two types External pacemakers and Internal pacemakers respectively. EXTERNAL PACEMAKER: External pacemakers are used on the patients with temporary heart irregularities, such as those encountered in the coronary patient, including heart blocks. They are also used for temporary management of certain arrhythmias that occur in the patients during critical postoperative periods and in the patients during cardiac surgery, especially if the surgery involves the values or septum. An external pacemaker usually consists of an externally worn pulse generator connected to electrodes located on or within the myocardium. External pacemakers, which include all types of pulse generators located outside the body, are normally connected through wires introduced into the right ventricle via a catheter catheter. The pulse generator may be strapped to the lower arm of a patient who is confined to bed, or worn at the midsection of an ambulatory patient. We have made the pacemaker which can be divided into two general categories namely Asynchronous pacemaker Synchronous pacemaker ASYNCHRONOUS PACEMAKER: This type of pacemaker is intended for patients having permanent heart blocks. The rate is preset. It can be varied externally within the range of 60 PPM to 180 PPM. Since this pacemaker functions regardless of the patients natural heart rhythm it poses a potential danger because of competition between the patients rhythm and that of the pacemaker. PACING PULSES FROM ASYNCHRONOUS PACEMAKER SYNCHRONOUS PACEMAKER: In patients who have normal heart function most of the time, asynchronous pacing can be extremely dangerous, working against their own physiological pacemaker with the danger of stimulating in the vulnerable period of the T wave, a condition that can result in fibrillation. The demand pacemaker consists of an ECG amplifier and a conventional pacemaker output pulse circuit that has been modified to allow output from the ECG amplifier to inhibit the pulse generator. This pacemaker senses R-waves and its timing and logic circuits count out an elapsed time interval following an R-wave or previously induced pulse. If the intrinsic R-wave does not appear before the elapsed time interval, the ventricle is stimulated. If an R-wave is received, the counter is reset again. This type of pacemaker is used for patients with bradycardia, and it ensures a heartbeat no slower than its set rate. PACING PULSES FROM SYNCHRONOUS PACEMAKER INTERNAL PACEMAKER: Internal pacemaker are implanted within the pulse generator placed in a surgically formed pocket below the right or left clavicle, in the left subcostal area, or in women, beneath the left or right major pectoralis muscle. Internal leads connect to electrodes that directly contact the inside of the right ventricle or the surface of the myocardium. The exact location of the pulse generator depends primarily on the type of the electrode used, he nature of the cardiac dysfunction, and the method (mode) of pacing that may be prescribed .Since there are no external connections for applying power, the pulse generator must be completely self contained, with a power source capable of continuously operating the unit for a period of years. BIO POTENTIAL ELECTRODES: A wide variety of electrodes can be used to measure bio electric events but nearly all can be classified as belonging to one of three basic types; Micro electrodes Skin surface electrodes Needle electrodes All three types of bio potential electrodes have the metal-electrolyte interface. In each case, an electrode potential is developed across the interface, proportional to the exchange of ions to the metal and the electrolytes of the body. MICROELECTRODES: They are used to measure bio electric potentials near or within a single cell.Microelectrodes are electrodes with tips sufficiently small to penetrate a single cell in order to obtain readings from within the cell. The tip must be small enough to permit penetration without damaging the cell. This action is usually complicated by the difficulty of accurately positioning an electrode with respect to a cell. Because of their small surface area, they have impedances well up into the megohms. For this reason, amplifiers with extremely high impedances are required to avoid loading the circuit and to minimize the effects of small changes in interface impedance. SKIN SURFACE ELECTRODES: Skin surface electrodes are used to obtain bio electric potentials from the surface of the body. They are available in various size. Although any type of surface electrode can be used to sense ECG, EMG, EEG potentials, the larger electrodes are usually associated with ECG, since localization of the measurement is not important. Smaller electrodes are used in EEG and EMG measurements. Various types of disposable electrodes have been introduced in recent years to eliminate the requirement for cleaning and care after each use. In general, disposable electrodes are of the floating type with simple snap connectors by which the leads, which are reusable, are attached. Although, some disposable electrodes can be reused several times, their cost is usually low enough that cleaning for reuse is not warranted. They come pre gelled, ready for immediate use. NEEDLE ELECTRODES: To reduce interface impedance and, consequently, movement artifacts, some electroencephalographers use small subdermal needles to penetrate the scalp for EEG measurements. They are also used to measure EMG potentials from a specific group of muscles. They are less susceptible to movement artifacts when compared with surface electrodes as they create an interface beneath the surface of the skin. By making direct contact with the subdermal tissue or the intercellular fluids, these electrodes also seem to have lower impedances than surface electrodes of comparable interface area. Even though needle electrodes have less motion artifacts ,surface electrodes are used to acquire ECG because surface electrodes are more convenient for the patient .Most of the surface electrodes are cheap and reusable. ACQUISITION OF ECG USING 3 LEAD SYSTEM LEAD I CONFIGURATION: ECG sensors measure the time-varying magnitude of electric fields emanating from the heart. ECG values are measured by placing non-invasive electrodes at the surface of the patients skin. For a 3-lead ECG sensor, the electrodes need to be placed in a triangle (Einthoven Triangle) on the patients chest as shown in the figure 11. Each corner of the triangle corresponds to one of the limbs: right hand, left hand, left foot. With the bipolar system, one limb is connected to the positive terminal of the amplifier and another limb to its negative terminal. Three limbs (right arm-RA, left arm-LA and left leg/foot-LL) are used. The right leg was used as earth, to minimize interference. ECG AMPLIFIER: Bioelectric signals have very high input impedance. To stop the signal attenuation, we use Instrumentation Amplifier (AD 624) which also has high input impedance. It should have high gain and low output impedance .In order to remove the common mode signals ,it should have a high Common Mode Rejection Ratio (CMRR of about 90 dB).The potential at the surface of the body ranges from 0 10 mV so the amplifier should have high gain (1000). We use a differential amplifier to amplify the bioelectric signals that occur as a potential difference between two electrodes, the bioelectric signals are applied between the inverting and non-inverting inputs of the amplifier. The signal is therefore amplified by the differential gain of the amplifier. For the interference signal, however, both inputs appear as though they were connected together to a common input source. Thus, the common mode interference signal is amplified only by the much smaller common mode gain. The electrode impedances form a v oltage divider with the input impedance of the differential amplifier. If the electrode impedances are not identical, the interference signals at the inverting and non-inverting inputs of the differential amplifier may be different, and the desired degree of cancellation does not take place. Because, the electrode impedances can never be made exactly equal, the high common mode rejection ratio of a differential amplifier can only be realized if the amplifier has an input impedance much higher than the impedance of the electrodes to which it is connected. There are different lead configurations such as 3-Lead, 5-Lead, 12-Lead for acquiring ECG Signal. We have used 3-Lead system Lead I Configuration. 12-CIRCUIT FOR ECG AMPLIFIER AMPLIFIER OUTPUT SOFTWARE IMPLEMENTATION USING LABVIEW: LabVIEW (short for Laboratory Virtual Instrumentation Engineering Workbench) is a platform and development environment for Visual Programming Language from National Instruments. LabVIEW is a graphical programming environment used by millions of engineers and scientists to develop sophisticated measurement, test, and control systems using intuitive graphical icons and wires that resemble a flowchart. LabVIEW offers unrivaled integration with thousands of hardware devices and provides hundreds of built-in libraries for advanced analysis and data visualization. The LabVIEW platform is scalable across multiple targets and operating systems. LABVIEW is a GUI (Graphical User Interface) which can be used for processing of signals, images and other forms of data. One of the most powerful features LabVIEW offers engineers and scientists is its graphical programming environment. With LabVIEW, one can design custom virtual instruments by creating a graphical user interface on the computer screen through which one can: Operate the instrumentation program Control selected hardware Analyze acquired data Display results One can customize front panels with knobs, buttons, dials, and graphs to emulate control panels of traditional instruments, create custom test panels, or visually represent the control and operation of processes. The similarity between standard flow charts and graphical programs shortens the learning curve associated with traditional, text-based languages. The behavior of the virtual instruments can be determined by connecting icons together to create block diagrams, which are natural design notations for scientists and engineers. With graphical programming, one can develop systems more rapidly than with conventional programming languages, while retaining the power and flexibility needed to create a variety of applications. We have used Lab view to acquire the signal, filtering and do other processing of the ECG signal. The real time signal is given into as input to ELVIS I which acts as the DAQ (data acquisition system).The block diagram of the Lab view implementation is as shown in figure 14. STEPS INVOLVED IN LABVIEW IMPLEMENTATION: The ECG signal from the amplifier (using AD 624) is given as input to DAQ for acquiring the signal in Lab view software. FFT of the ECG signal is obtained and viewed. We can see the frequency content of the ECG signal from the FFT obtained. WE can also see the presence of 50 Hz power line interference in the FFT of raw ECG. A Smoothing filter with following specifications Moving average, Rectangular filter with a half width of 20 is constructed. The Smoothened ECG is viewed. Smoothing Filter is used to remove noise and 50 Hz power line interference. The Smoothened signal is given as input to the Butterworth Band Pass Filter of order 2 and a low cutoff frequency of 5Hz and high cut off frequency of 15Hz.Band Pass Filter is used to separate the QRS complex from the ECG Signal. The output of the Band Pass Filter is differentiated and squared inorder to enhance the QRS complex from the remaining portion of the waveform. The heart rate is calculated using timing and tone measurement block. The block gives the frequency of repetition of the QRS complex. The frequency value is converted into time value by taking inverse of it. Heart rate is calculated as follows. Heart Rate = 60/R-R Interval Example: R-R Interval = 760ms Heart Rate = 60/760ms = 78.94 Beats /Minute If the calculated heart rate is below the normal value, then pacing pulses are produced .This is done by using a case structure. The case structure turns on only when the case is true (Heart Rate is below normal value).Inside the case structure we have a square wave generator. The output of the square wave generator is differentiated and squared. We get a pulse as a result of these operations. The rate and amplitude at which the pulses are produced can be modified easily at run time using controls. Whenever the heart rate is normal, False condition is selected . For false condition, we set the amplitude and frequency of the square wave as zero so that the pacemaker is switched off. The Pacing Pulses generated can also be taken out as an analog voltage from the ELVIS and can be viewed in a DSO. Only voltages in the range +10 volts to -10 volts can be taken out from LABVIEW through ELVIS. PACEMAKER FINAL BLOCK DIAGARM. FRONT PANEL IN LABVIEW ENTIRE SOFTWARE IMPLEMENTATTION We have implemented the case structure and other blocks by studying the general tutorials given in LV BASICS 1 MANUAL and LABVIEWBASICSII_85_ENG CLAD. HARDWARE IMPLEMENTATION: BLOCK DIAGRAM FOR HARDWARE IMPLEMENTATTION BAND PASS FILTER: The amplifier which is used in software implementation (AD 624) is also used here. It is followed by a filter. The amplifier output is around 550 mV. A Filter is a circuit that is defined to pass a specified band of frequencies while attenuating all signals outside this band. Filter networks may be either active or passive. Passive filter networks contain only resistors, inductors and capacitors. Active filters employ transistors or op amps plus resistors, inductors and capacitors. Inductors are often used in active filters, because they are bulky and costly and may have large internal resistive components. Band Pass Filters pass only a band of frequencies while attenuating all frequencies outside the band. A simple high pass filter followed by a low pass filter will form a band pass filter. We have used a band pass filter (0.5Hz 40 Hz) to remove high frequency signals like EMG and low frequency components like Base Line Wandering and motion artifacts. We have used a second order Bu tterworth Filter with -40 db/decade roll-off. For Low Pass Filter, we used 0.5 Hz as the cut off frequency.C1 is chosen as a convenient value between 100 pF and 0.1Â µF.For High Pass Filter, we used 40 Hz as the cut off frequency. We have implemented a Band Pass Filter according to the design given in OPERATIONAL AMPLIFIERS AND LINEAR INTEGRATIONAL CIRCUITS. CIRCUIT AND DESIGN FOR BAND PASS FILTER NOTCH FILTER: A Notch Filter transmits frequencies in the pass band and rejects undesired frequencies in the stop band. In applications where low level signals must be amplified, there may be present one or more of an assortment of unwanted noise signals. Examples are 50, 60 0r 400 Hz frequencies from power lines, 120 Hz ripple from full wave rectifiers, or even higher frequencies from regulated switching type power supplies or clock oscillators. If both signals and signal frequency noise component are passed through a notch filter, only the desired signals will exit from the filter. The noise frequency is notched out. We have designed a active notch filter (using LM 324) to remove 50 Hz Power Line Interference. The amplitude of the acquired ECG signal is around 1 2 V. We got noise free ECG for real time signal acquisition as shown below. CIRCUITAND DESIGN FOR NOTCH FILTER REAL TIME ECG ACQUISITION QRS DETECTOR: In order to extract the QRS Complex from the ECG signal obtained, we use a band pass filter with center frequency of 17 Hz and band width of 6 Hz. The QRS signal obtained from the band pass filter is rectified for comparing with the threshold voltage generated by the detection circuit. The filtered and rectified ECG is stored on a capacitor. This filtered and rectified ECG is compared with the fraction of this voltage. Whenever a threshold voltage is exceeded, the QRS pulse is detected. After the detection of every QRS pulse, the capacitor recharges to a new threshold value after every pulse. CIRCUIT FOR QRS DETECTION MONOSTABLE MULTIVIBRATOR: Monostable Multivibrator generates a single output pulse in response to an input signal. It is also known as One Shot Multivibrator. The time period of the output pulse depends only on the external components (resistors and capacitors) connected to the op-amp. The duration of the input triggering pulse can be longer or shorter than the expected pulse. The duration of the output pulse is represented by the T. Since T can be changed only by changing the resistors and capacitors ,the one shot multivibrators can be considered as a pulse stretcher. This is because the width of the pulse can be longer than the input pulse. In a stable or standby state, the output of the multivibrator is zero or low-level logic. The output of the multivibrator is forced to go high (ËÅ"Vcc) when an external trigger is given. The output stays zero until the next triggering pulse is given. Then the cycle repeats. The monostable multivibrator has only one stable state. Hence, the name monostable. The QRS detector gives a pulse for QRS detected which is given as an input trigger for a monostable multivibrator. This monostable multivibrator is used to produce a positive pulse (amplitude 5V) of desired pulse width for every input triggering (negative edge triggering) from the QRS detector. We had used 555 Timer as a monostable multivibrator. MULTIVIBRATOR OUTPUT Thus, the analog section of the project gets over with multivibrator. The output of the multivibrator is processed using PIC18F 4550 Microcontroller. It marks the beginning of the controller section. MICROCONTROLLER: PIC is a family of Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1640 originally developed by General Instruments Microelectronics Division. The name PIC initially referred to Programmable Interface Controller, but shortly thereafter was renamed Programmable Intelligent Computer. PICs are popular with developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, and serial programming (and re-programming with flash memory) capability. Like all Microchip PIC18 devices, PIC18F4550 family are available as both standard and low-voltage devices. Standard devices with Enhanced Flash memory, designated with an F in the part number (such as PIC18F4550),accommodate an operating VDD range of 4.2V to 5.5V.Low-voltage parts, designated by LF (such as PIC18LF4550), function over an extended VDD range of 2.0V to 5.5V. Our project uses a standard PIC 18F4550.Hence this microcontroller uses a flash program memory of 24K bytes .It is a 8-bit microcontroller and so they handle data as 8-bit chunks. PICs have a set of registers that function as general purpose ram. Special purpose control registers for on-chip hardware resources are also mapped into the data space. The addressability of memory varies depending on device series and in PIC 18F4550 external code memory is directly addressable which is an exceptional feature compared to baseline and mid line core devices. PICs have a hardware call stack, which is used to save return addresses. The hardware stack is not software accessible on earlier devices, but this changed with the 18F4550 device. Hardware support for a general purpose parameter stack was lacking in early series, but this greatly improved in the 18F4550, making the this device architecture more friendly to high level language compilers. Core features All of the devices in thePIC18F 455 series family incorporate a range of features that can significantly reduce power consumption during operation. Key items include: Alternate Run Modes: By clocking the controller from the Timer1 source or the internal oscillator block, power consumption during code execution can be reduced by as much as 90%. Multiple Idle Modes: The controller can also run with its CPU core disabled but the peripherals still active. In these states, power consumption can be reduced even further, to as little as 4% of normal operation requirements. On-the-Fly Mode Switching: The power managed modes are invoked by user code during o

Skinheads in the Antelope Valley :: essays papers

Skinheads in the Antelope Valley William Finnegan's essay "The Unwanted" explains the history and make-up of the Antelope Valley and then explores the lives of some teenage citizens in order to discover reasons that two rival gangs have such a significant role in the community and on its people. Absent parents and lack of education are just two factors facing teens that ultimately led the Los Angeles Suburb into becoming a society where Skinheads and Boneheads are a norm and accepted as a part of everyday life. C. Wright Mills' idea of the sociological perspective, looking past the facades, is useful when analyzing the micro; individual, and macro; broad, causes of teens becoming skinheads. Each day America seems to become more and more diverse. Some people learn to accept the fact that America is made up of many different ethnic groups, while others believe the only ethnic group should be their own. There are various reasons for discrimination and it is a very controversial issue. In Finnegan's article he describes two gangs with opposing views concerning racism and how each group expresses their beliefs. The racist and anti-racist beliefs don't always end at the individual. Death is an all too common end and when an opinion becomes life threatening a problem arises. According to Finnegan, one of the two major gangs that occupy the streets of Lancaster and the Antelope Valley is, "a white-supremacist skinhead gang, the Nazi Low Riders (N.L.R.'s)" and the other is, "their rival gang of anti-racist skinheads, the Sharps" (1998, p.88). One major quality the two gangs share is their lack of education. Most, if not all, of the teens Finnegan interviewed, dropped out of school, even though later some used other means of getting a high school diploma or acquiring a higher education. Also it appears both gangs tend to resolve their issues with violence. Most people would agree that some violence is in everyone, but it seems that well educated people often find other means to conquer their problems or go about solving them. Through history knowledge has proved to be an unavoidable part of life. As children in the community began dropping out of schools in vast numbers these kids were forced to, willingly or not, gain knowledge elsewhere (1998). A macro cause for the growing numbers of students dropping out of school and joining the gangs, could be that the ideas and values of those gangs quickly spread through the streets and classrooms. This Leads the teenagers to make decisions about wether or not they agree with the

A Surrogate Motherhood, Pros and Cons

A Surrogate Motherhood, Pros and Cons A surrogate mother means a woman who agrees to have a child for a couple who are childless because of infertility or not able of having a child due to a number of physical dilemmas. The procedure engages artificial insemination method, whereby the husband’s sperm is transferred and the surrogate mother accepts it. That is why the surrogate mother is still considered as the real mother of the child. However, in case of gestational surrogacy, the wife is fertile but not competent of giving birth due to some medical problems, it is called in-vitro fertilization technology.The wife’s eggs and her husband’s sperm are used and the resulting embryo is transferred into the uterus of the surrogate mother. The concept of surrogate motherhood is becoming very accepted way of infertile couples to have a child of their own. Although it is an act of love, it also involves financial aid. Surrogate mothers are obviously paid for bearing a ch ild inside their wombs. A couple who wants to hire a service of a surrogate mother must also consider the kind of personality of the surrogate mother. We all know that the genes have larger effect on the baby’s personality someday.Another very important ground for the rise in surrogacy is the progression in medical technology. It is more secure and successful unlike other medical technologies available. However there are some authorized and moral issues concerned with surrogacy that needs to be discussed. Legal procedure: The process for becoming a surrogate mother is not easy. There have to be convinced medical tests such as Hysteroscopy, this kind of test is done to make sure if fallopian tubes are clear or not, and physical conditions of the uterus is also take in consideration.Before the fertilization process, the surrogate mother should know her legal rights and before signing a contract, a service and a legal adviser or lawyer is necessary to make sure that the right of the surrogate mother will not be neglected by the couple involved. Ethical issues: Surrogacy perception brings quite a lot of controversies, although things are changing with time. Some of them are: the surrogate mother may decide to take the baby without the concern of the couple involve. Surrogacy could be considered as human trafficking. Percentage of the society that accepts the concept of surrogacy.Sometimes, guilt arise to the surrogate mother and the emotion enclosed in it arise when you least expect it. Especially, if there are papers and money issue involves in the process of surrogacy. In spite of the authorized and moral issues concerning surrogacy, still it is a new hope for childless women and family around the world which they can have through surrogate mothers. Deciding on Surrogacy Surrogacy makes it possible for childless couples to have a child with genes from either one or both of them. This is why couples often choose surrogacy over adoption.Surrogacy is a viabl e option for couples when one is infertile, when the woman may be fertile but unhealthy to bear a child, or for gay couples. One of the disadvantages of surrogacy is the potential emotional and psychological roller-coaster rides couples go through. Furthermore, they also have to deal with trying to convince family members and close friends that this is the right thing to do. The couples may take a while to assess their situation and consider all the factors before they can make their final decision, which can take a toll on their daily lives.Surrogacy is a very controversial subject. Some religious organizations forbid their members from participating in surrogacy, no matter how desperate they are to have a child. Whatever the reason that couples might consider surrogacy, they must carefully weigh the pros and cons before proceeding. There are different factors that people who are considering surrogacy have to go through, from the time to decide whether they would go forward with it , to choosing the surrogate mother, the procedures involved, the fees required and the overall time frame.Each of these factors has its own pros and cons. Why is it that every time someone mentions the topic of surrogacy, giant waves of powerful emotions come washing in from both pro and con surrogacy camps? One of the reasons is that surrogacy is balancing on a very sharp ethical edge when mixing the perceived sacred process of reproduction and having children with work and money. Many people believe that these two domains should not mix. I'm neither pro nor con surrogacy. I'm just interested in exploring the philosophical and emotional dimensions of the ethics of surrogacy.I will now present the pros and cons of surrogacy. I will not comment on them or judge them; I will just list them and then leave the opinion making of the ethics of surrogacy open. Pros Surrogacy allows a woman to give the gift of parenthood to a couple who would otherwise not have been able to experience it, e ither due to infertility or inability to adopt a child. In some cases, the surrogate can also obtain monetary compensation for her services. Cons Surrogacy involves a lengthy and medically invasive process for the surrogate mother.It can also involve guilt on the part of the surrogate mother for giving up her baby; in some cases, this guilt leads to the surrogate changing her mind. Additionally, there are a myriad of legalities involved. Having a surrogate mother Pros †¢No physical pain of child birth. †¢No pregnant belly being in your way all the time. †¢ Still be able to work. Cons †¢No experience of the full pregnancy first hand †¢Constant worry about what the surrogate is doing. As a conclusion I want to give my opinion, surrogacy is a good way for some women to help others that can not have a baby.Before deciding to pursue surrogacy as an option for having a child, it’s wise for couples to spend some time considering both the pros and cons of the issue. Surrogate motherhood enables infertile couples to have children and fulfill their parenthood dream. Many infertile couples turn to surrogate mother rather than to adoption. The reason is because surrogate motherhood is a better form of alternative than adoption, as surrogate motherhood ensures the child is biologically related to the commissioning parents.References The ethics of surrogacy: women's reproductive labor.

Solvent and Solubility essays

Solvent and Solubility essays In this experiment, several organic chemicals were tested for their solubility. These organic chemicals are acetone, ethanol, ethyl acetate, ethyl ether, hexane and methanol. They were put to test with potassium bromide (KBr), an ionic compound, benzoic acid, an organic acid, and water. CH3 wCH2 wO wH CH3 wC wO wCH2 wCH3 CH3 wCH2 wO wCH2 wCH3 CH3 wCH2 wCH2 wCH2 wCH2 wCH3 C wO wH O Potassium Bromide Benzoic Acid Water The functional group of acetone is ketone, it contains a C=O and it has a dipole moment. Both ethanol and methanol has the same functional group, hydroxyl group, OH. Ethyl Acetate has a C wO group commonly known as an ester group. Ethyl ether contains an ether group which structure looks like R wO wR ¡. Hexane doesn ¡t have any functional group but only C wC bond linked together. Potassium bromide is an ionic compound which will separate into K+ and Br- when put into water. Benzoic acid is an organic acid with a benzene group and a carboxyl group, C wOH, it is also capable for hydrogen bond. The hypothesis for the solubility behavior of potassium bromide in water and in hexane is that potassium bromide would most likely to dissolve in water but not in hexane. This is because of the polar property of chemicals. In water molecules, the hydrogen atoms have a partial positive charge and the oxygen atom has a partial negative charges. The positive ends of the water molecule strongly attract the negative ends of other polar compounds, in this case the bromine atoms of potassium bromide. Likewise, the negative ends of water strongly attract the positive ends of neighboring compounds, the potassium atom...

Representation of gender in Wong Kar Wais movies Essay Example

Representation of gender in Wong Kar Wais movies Essay Example Representation of gender in Wong Kar Wais movies Paper Representation of gender in Wong Kar Wais movies Paper Essay Topic: Film Men, who are masculine, physically strong, aggressive, intellectual, active, in dependent, production and rational; Women, who are feminine, weak, submissive, passive, dependent, consumption and emotional. Such gender stereotypes of male and female had deeply rooted in our society and had became a hegemonic definitions between men and women. The hegemonic definitions of Men and Women are more explicit in movies. There are traditional gender roles in movies, especially in main-stream commercial movies, male characters are usually strong, powerful, tough, dominate (female) and heroic; while female characters are usually being- rotected, weak, femme fatale and desire for love and romantic. These traditional gender representations on screen have been generally accepted / accustomed by audiences. Hence, producers and directors tend to follow the gender stereotypes of male and female, no matter they are producing / directing a rom-com, martial film, tragedy or cop-robber film. In this article, Im going to look into Wong Kar Wais movies, which categorized as alternative, and find out hows the differences and similarities in gender representation between his film and other commercial, main- stream movies. Firstly, I want to state some similarities in gender representation between Wongs movies and main-stream movies. Something very interesting is women are always femme-fatale in Wongs movies. Maybe they have no intention to make troubles, but hey are really mentally / physically destructive to men in his movies. For example, in the movie Fallen Angels, the female agent (Michelle Reis) employed by the hired killer Wong Chi Ming (Leon Lai) is obviously a femme-fatale to himself. In the movie, the killer tried avoid to meet or even have connection with his agent because e thinks they could no longer to keep on their partnership if theres any relationship or friendship between them. The agent played by Michelle Reis is totally invisible in the killers life. Before killer Wong Chi Ming meet his agent, he completes every mission assigned by her excellently. However, once the killer meet his beautiful female agent, death comes and knock his door. Hes attracted by his agent and want to terminate his business relationship with the agent. She asks him to kill someone as a parting favor, but Wong Chi Ming turns the hit into a suicide mission and died. Perhaps the pretty agent doesnt mean to make her partner die, but she is obviously a femme fatale in Wong Chi Mings destiny. Other than Fallen Angels, women also acted as femme fatale or trouble-maker in his movies. For example, in the 2 stories of ChungKing Express, 2 cops are lost themselves and deeply hurt after dumped by their girlfriends. In this film, both of the cops 223 (Takeshi Kaneshiro) and 633 (Tony Leung) fell into lovesick after broke up. Cop 223 became a man without his soul and started to addict to canned-pineapples after his girlfriend left. He was hurt by his ex-girlfriend and even cannot thinking logically. He drunk himself, call his old classmates with no reason, run in the rain, meet stranger in bar all of this action mean he has got troubles in his mind and these troubles was caused by his girlfriend. In the second part of the film, Cop 633 also hurt by his girl, he started to talk with Dolls, towel, soap etc. n his house, he lost his sense and just like Cop 223, many crazy thinking blow up in his mind. In this film, women play the role of trouble- maker again that make 2 men become the victim in love and suffer from lovesick caused by women. In Happy Together, a love story about 2 men, we can also see the emme fatale, troublemaker image of women. There is heres no female character in this film, howe ver, Ho Po Wing (Leslie Cheung) is playing the female role in the romance between Lai Yiu Fai and him. In this film, we can see Ho Po Wing is totally rely on his boyfriend Lai Yiu Fai and caused a lot of troubles to him. Ho spent all of Lais money that Lai cannot return to Hong Kong. Ho betrays Lai in love again and again. In the early part of the film, Ho and Lai failed to go Iguazu Fall and lost their way due to Ho Po Wings mistakes. However, in the late part, after Ho left Lai, Lai Yiu Fai travel to Iguazu Fall alone and he could arrive the Fall at last. If you compare this 2 scene, you would find that female played the role of troublemaker again. Except the image of femme fatale, something in Wong Kar Wais films is quite similar to those main-stream movies. That is women are always act as homemakers or helpers for men. In Fallen Angel, killer Wong Chi Mings female agent find business for him and make decision for him. She decides who will be killed, how, where and when. She also go to his apartment and do housework for him when hes not there. In Chungking Express, Faye (Faye Wong) get the key of Cop 633s partment and break into 633s flat while hes away. She cleans 633s flat and redecorated with new bedspreads, new clothes, new toiletries, new food. Faye even drugs 633s bottled water to make sure he gets to sleep. Both killers agent and Faye are playing the tradition role of women as homemaker and helper for men. However, they are doing these works for non-traditional purposes. Traditionally, women are stereotyped as housewives. They do housework and other things for men just because of responsible. But both the killers agent and Faye are not clean and decorate their mens flats because they have to act like housewives. They do housework for men in the purposes of fulfil their suspicions and satisfying themselves rather than acquiescing to the role of the stereotypical homemaker and be a home maid for men. Other than the those similarities mentioned above, we can find some differences in gender representation between Wong Kar Wais films and other main-stream movies. One of those differences is the representation of men. In Wong Kar Wais films, men are no hero or even weak behind their muscular body. In Fallen Angels, killer Wong Chi Ming claims to have become a contract killer because he is lazy and likes to ave others make decisions for him, so he is not presented as a hero. We never know why any of Chi-Mings victims are marked for death, he takes others life because its his job. He kills people just because he completes his duty, like post officer deliver letters, but no relation to any sense of heroism. Moreover, Wong Chi Ming fails to complete his mission and being shot down at last. The scene of Wong killed in action is totally violate to the tradition of heroism that hero are never defeated. So, Wong Chi Ming is not hero but a normal person like you and me. In Chungking Express, weakness of men is more clearly shown. Both 223 and 633 are Cop and they are traditionally supposed to physically and also mentally strong. However, we cant see Cop 223 and 633 act like hero to stop crimes and maintain law and order in the movie. Instead, we can see hows their weak image after deeply hurt by their girls. 223 forces himself to eat a can of pineapple everyday and talk to his dog to release his anxiety, while 633 hugs and chat with his dolls, dreams of his ex-girlfriend will come back soon. All these action shown men can be weak or even weaker than women sometimes. Such weak image of men is far different from the tradition which men hould be tough in physically also mentally. On the contrary, women in Wong Kar Wais films were tough, independent, free-spirited, calm, cool and usually less emotional than men. The most typical example in Wongs film is the drug smuggler (Brigitte Lin) in Chungking Express. Shes in cool style that blonde-wigged, wears long coat, and sun-glasses, always with a gun in her purse. She keeps calm when she is chasing by people want to kill her and shoots down her master and also those drug couriers who double-crossed her. She is actually playing the role of hero and presenting heroism which traditionally played by men. Women in Wong Kar Wais film act active and can say to be aggressive in many aspects, especially in love. Women usually be the active side in romance. They dare to get close to guys they liked and no fear to take action to attract mens attention. Maybe people may think that Wong Kar Wai presents women in this way just because following the traditional patriarchal ideology and fulfilling what men wanted (women play the active role in love) and have no different to the main-steam films. But in my point of view, women be active in love means they are liberated, freed in love. In Wongs movies, women no longer wait for mens love, they are not products on shelf and wait for someone to pick them up. They have rights and freedom to choose, to approach those guys they loved. For example, in Chungking Express, Faye loved Cop 633 from her first sight on him. She doesnt wait for 633 put attention on her, instead, she decides to break into his flat to discover him. She cleans and wander in his flat everyday in order to fulfil her romantic feeling on him. One more example, Baby (Karen Mok) in the Fallen Angels seduces Wong Chi Ming into a sexual relationship. I dont think its presenting the idea of patriarchal, but presenting an idea that women can be active in love or even sex. In opposition, Men are more passive than women. No matter Lai Yiu Fai in Happy Together and Chow Mo Wan in In the Mood for Love, they choose to keep their feeling of love inside instead of tell the person they like. Lai Yiu Fai has special feeling to his co- worker Chang (Chang Zhen), but he chooses not to tell him and let him leave. Similarly, Chow Mo Wan fall in love to his neighborhood Su Li Zhen (Maggie Cheung). But he chooses not to tell how deep he loves her and keep it as secret. To avoid get involve between Su and her husband, Chow leaves Hong Kong and mine his secret (his love to Su) in the tree hole. Obviously, men and womens roles of love in Wongs movies are quite different from other films. In conclusion, gender representation of men and women in Wong Kar Wais films have no bias any side. Neither men nor women are superior to each other. However, binary opposition between two sex is always played in Wongs films. Rivalry between men and women is always the main theme of his stories. We can see mind games between two sex in his films, each of them compete for control, regulate and dominate its other.
