Existentialism Is a Humanism Essay Example for Free

Existentialism Is a Humanism Essay Sartre is attempting to safeguard existentialism against some objection to it. The Communist condemned existentialism as an encouragement to individuals to check out sad world issues. Then again, Christians censured from the way that individuals preclude the need from claiming consideration in human issues. Individuals have the will to do anything they need and wish. With the model given, about disregarding the Ten Commandments, we can individuals prevent the incentive from claiming following the rules and will possibly tail it in the event that they wish. THE MEANING OF EXISTENTIALISM. As indicated by Sartre, existentialism is a rule that gives human life conceivable. It additionally establishes that each reality and activity we know includes both an ecological and a human subjectivity. The two kinds of existentialist are the Christians and Existential Atheists. What they share for all intents and purpose is that the two of them put stock in â€Å"existence precedes essence†, which implies that a human has no foreordained substance or nature. â€Å"Man is nothing else except for that which he makes of himself. † If a man can't characterize himself, at that point he will undoubtedly happen that he is nothing. The paper-blade model discussions about how a craftsman conceptualized an article, how he gave close consideration to it and realized what the motivation behind the item would be. The paper-blade is existentially not quite the same as human in light of the fact that for Existential Atheists, which Sartre is incorporated, man characterizes himself and not the maker that imagined him. Obligation A ramifications given in the talk is the way a being would have the option to presence would precede its embodiment regardless of whether God doesn't exist. Sartre referenced that there is no human instinct since we characterize ourselves and not by any power that lives inside us. By Sartre saying that â€Å"in deciding for himself, he decides for all men†, he implies that when people decide, it insists that estimation of which he had picked. The decisions we consider are consistently the better, and nothing can be better for us except if it is better for all. At the point when a human decides to accomplish something for himself, such as wedding and have youngsters, he is as yet making and contributing a picture for the entire the entire humankind. ANGUISH Existentialist honestly express that man is in anguish since he just chooses for himself, not understanding that the entire humankind is settling upon his shoulders. When we are in skirt of act, we ought to ask ourselves â€Å"What would occur if everybody did as such? † In asking this, we would have the option to completely rethink the activities or choices we’re going to do. In the account of Abraham and the daydreaming ladies, we are instructed on the best way to pose ourselves with that inquiry. It isn't sufficient to do a demonstration with simply hearing the order. We ought to demonstrate to ourselves that what we are going to follow would be sensible and just. Deserting Sartre said that if God didn't to exist, nothing would truly change. He accepted that we would in any case have a similar advancement that we have now. Be that as it may, for the existentialist, they would be humiliated on the grounds that it vanishes with God the chance of discovering esteems in a coherent paradise. For Dostoevksy, if God didn't exist, everything will be allowed. He said that human would be liberated from doing anything they wish. One will be always to be unable to clarify one’s activity since he doesn’t have anything to allude to. Then again, he suggests that if God doesn't exist there wouldn’t be qualities or orders that will legitimize our conduct. Existentialists put stock in the intensity of enthusiasm. They accept that man is answerable for his energy, not some drive that is covered up inside a man. The tale of the understudy instructs us that we should confide in our sense. With his situation, regardless of whether to join the Forces or to remain with him mother, he put together his choice with respect to what he felt. Since he had been living with his mom, the benefit of feeling to be consistently close by is created. Along these lines, he decided not to live his mom. Moreover, the Jesuit’s story discloses to us that through our choices and activity, we will undoubtedly pick our own way and bear the whole duty. Hopelessness According to Sartre, the meaning of sadness is that â€Å"we confine ourselves to a dependence whereupon is inside our will, or inside the entirety of the probabilities which render our activity doable. † I think the motivation behind why Sartre imagined that when Descartes stated, â€Å"Conquer yourself instead of the world,† what he implied was â€Å"we should act without hope† is on the grounds that the two explanations are stating that we ought to be in charge of ourselves. The Marxists accept that you can depend upon the assistance of others. That in any event, when you kick the bucket, other will at present proceed with what you did and help. While Sartre’s contention is that he can't completely confide in those individuals he doesn’t know. Indeed, he can depend his works and existence with his confidants and family, however not to outsiders. Does that imply that I should forsake myself to quietism? NO. What we ought to do is to submit ourselves at that point demonstration the dedication made. Sartre expressed that man is nothing else than what he proposes. Since he hasn’t discovered anything yet he looks for, he keeps on living until the day he discovered it. â€Å"You are nothing else except for what you live†, this implies â€Å"a man is no other than a progression of undertaking, that he is the aggregate, the association, the arrangement of relations that establish these endeavor. † Behaviors of the individuals are brought about by the activities occurring in their condition upon them. The suggestion given was the way a quitter turned into a weakling, and a legend turned into a saint. Being a defeatist is the demonstration of surrendering. How harshness of idealism here is seen on how a man can make himself a defeatist or legend, through his activity and thinking. At long last, what checks is that â€Å"the predetermination of man is put inside himself. † There wouldn’t be any expectation or changes except if he begins accomplishing something. SUBJECTIVITY What Sartre and Descartes both concur on is that reality should initially have an essential fact of the matter. If not, it will disintegrate into nothing. Sartre feels that the hypothesis alone is incongruent with the nobility of man in light of the fact that â€Å"it is the one in particular which doesn't make man into an article. † Their primary point of that view is to recognize the human realm as example of qualities to that of the material world. THE OTHER Sartre accepts that when we are attempting to think to find ourselves, we are to find everything from others. To perceive oneself is to be perceive by others. With â€Å"I can't acquire any reality at all about myself, aside from through the intercession of another†, Sartre is stating that we need other to look for reality that we are attempting to discover. That being an individual isn't sufficient to discover reality and personality. Between SUBJECTIVITY We ought to comprehend that â€Å"all the constraints which from the earlier characterize man’s central circumstance known to mankind. † The authentic circumstance of each man is unique in relation to what they encountered. Human condition is stating that from having opportunity, we are additionally qualified for assume full liability of it. I think it is conceivable to comprehend and esteem something pretty much all individuals on the grounds that there is still all inclusiveness, which imply that in some way or another we can even now comprehend things outside ourselves. Dishonesty One of the suggestions are â€Å"every man acknowledges himself in understanding a sort of humanity†, implying that if a man chooses to arrange himself, he would have the option to acknowledges himself. There is no contrast between free being and outright being. Deceiving yourself by saying that it doesn’t matter to you is a dishonesty. It isn't right to state that what you pick doesn’t matter to you. Individuals can generally pick, yet in not picking is as yet a decision. â€Å"†¦without reference to any pre-set up esteem, yet it is shameful to burden him with inclination. † I do concur what he is attempting to state here. Since he has no information on a pre-set up esteem, there is no unexpected change in his decision. At the point when Sartre that we make ourselves, what he implied is that through our activities and choices we are framing our personality. Opportunity In saying â€Å"You can't judge others†, it is valid in one sense and bogus in the other. At whatever point a man picks his choices and reason, it is presently difficult to pick another. It is valid as in we don't have faith in progress. The objective of opportunity is to pass judgment on the consistent worth and not a judgment of significant worth. They likewise look for the genuine significance of opportunity. By what method can the existentialists structure judgment? By saying that he deludes himself and by doing that you are having acceptable confidence. â€Å"One can pick anything, however just on the off chance that it is upon the plane of free responsibility. † With this, we can reason that choosing decisions including the responsibility of oneself. Creation OF VALUES His reaction is a similarity, â€Å"if I have prohibited God the Father, there must be someone to imagine esteems. † He differs on the sort of humanism that accepts man as an end. He says so in light of the fact that man is still to be resolved and ought to be considered as an end. What he implied by â€Å"Transcendence† is a man’s connection to his reality and that of the individuals around him. Since man needs to outperform what he has done, he is in the focal point of his greatness. A man can understand himself as genuinely human when he chooses for himself, consistently look for truth and past himself and having a point of some specific acknowledgment. End From his perspective, regardless of whether God didn't exist, it would have no effect. Since for existentialists the genuine issue is the means by which man will have the option to end up to so as to spare himself, by not giving full dependence of God’s presence. Existentialism is a precept of activity such that they restrict their own despondency with existentialists that Christians ca

Our writers will create an original "Hsbc infrastructure company" essay for you Create order YIELD CURVE ANALYSIS A yield curve is a curve that represents a relationship between maturity of coupon bearing bonds and their yield to maturity. This means that it depicts the yields that are obtainable in relation to various bonds, bills or notes on their maturity. (Grandville, 2001) Generally, these curves are upward sloping as the investors who invest for short period have a safe investment against that of a long term investor who has to face a world full of uncertainties for quite a lot of time. Thus, they are offered risk premiums so as to persuade them to invest for long time. (Vanhorne Wackowicz, 2008) Depending upon the behavior of the market, the central banks and the attitude of the investors and their predictions, there are different shapes that can be taken by a yield curve. One of the most common type of yield curve is an upward sloping (or more generally called as positive curve) in which yield increases as the maturity of the bond increases. Apart from the most common one, other shapes that are prevalent occasionally are of three types. An inverted yield curve (or a downward sloping curve) is the one in which yield does not increase with the maturity time. Another type of yield curve is a humped yield curve which has ups and downs along the line as the maturity grows. And, in the end, there is a flat shaped yield curve. In this type of yield curve, all the maturities have the same yield irrespective of the time frame. A humped and a flat yield curve shows that the investors are uncertain of the market behavior. (Fabozzi, Mann Choudhry, 2003) The UK Yield curve that is under consideration has been dated on 12th December 2009. The UK curve exhibits all different types of yield curves. In the beginning, for a 1-month treasury note, the interest rate that is applicable is 0.47%. And, a 3-month treasury note has a interest rate of 0.47% while a 6-month note would give returns at the rate of 0.49%. As the trend can be seen, the curve gives almost the same return for a 1-month to 6-month treasury notes. This type of yield curve is a flat shaped yield curve. This shows that the investors are unsure of the economy in the near future and have very less expectations. Also, it indicates stable interest rates in the near future i.e. lending rate by the bank of England is not likely to increase in the near future and the economy is tightened by the government. The interest rate paid on a 2-year maturity bill is 1.23%, and on a 3-year maturity bill is 1.69%. While a 5-year bill has a return of 2.69% and a 10-year bond has a return of 3.88%. This period has seen a sharp rise in the predicted yields of an investment in the economy. It indicates that the investors would like to be paid an extra risk premium for blocking their money for such a long time. This is due to the level of uncertainty and increased chances of the investment being sunk. Investors anticipate a growth in the economy in this period as the country has just come out of recession and the government is taking all possible measures to get rid of this devil. Also, investors anticipate the inflation rates to increase rather than decrease. This is due to the fact that if the inflation rates increase, then the central bank has to squeeze the monetary policy by increasing the short term rate of interests. This is done so as to slower the economic growth of the nation and reduce the pressure of inflation over the market. Post this 10 year period, it can be seen that the interest rates have again come to a flat position or to be more precise a bit of inverted in the end. This can be due to the fact that the investors are not expecting any further increase in the inflation rates in the near future. So, if the expectations are of inflation levels being low in the future, then the investors would get a lower premium for their investments for a longer period. Another aspect of the same story can be the expectation of no increase in the interest rates by the central bank. Also, one of the more probabilistic chances are that UK being a developed nation, other countries might jump in to buy the treasury notes and bonds. In the past, Central banks of developing nations have jump in to buy the long term bonds of developed nations. This then leads to a flat yield as the demand in the market for the bonds is huge. Another concern being that the most hated word, recession, can again come into play as the economy is seen to be heading towards another situation where liquidation problem may arise and the interest rates are again seen going down or coming to a halt. PART-B: On study of HICL, 50 day moving average for past 3 years i.e. since its launching in the stock market, No. of signals generated = 14 No. of buy signals = 7 No. of sell signals = 7 Thus, ratio of positive returns/ total signals = 7/14 = 0.5 The ratio is exactly 0.5 i.e. the chances are even that the investment made by following the 50-day moving average method would yield a return. A moving average is a interesting tool used to depict the trend of the share prices in consideration. It is generally helpful in order to invest in a market where the share price of the stock is fluctuating. A moving average trend is the summation of closing price of the shares divided by the no. of days in consideration. In simple words, it is the average of the closing stock prices of the company in relation to the number of days. (Edwards, Magee and Bassetti, 2001) The fundamental rule to invest by following a 50 day moving average is to generate a buy signal, when the share prices line cuts the moving average curve from below. While, a sell signal is generated when the share prices of the concerned company cuts the moving average from above. Moving averages are helpful when the trading conditions for the shares are favorable, i.e. smooth trends, but mostly they attract the investors to make losses by investing through study of a moving average trend. (Stewart, 1996) One of the main problems with the moving average method is that it can be unpredictable at times. It reacts to any piece of information twice i.e. once, when any new information is added to draw the curve ahead and secondly, when the last information is dropped off from the moving average curve. This means, that if the last information is a high price, then the moving average would move down. While, in case, if the last price is a low price, then the moving average is likely to move up, irrespective of the share price of the new day that has been added to draw the moving average curve. Another drawback of the method is that they tend to delay the attitude of the market. This is the price that the investors in the market are ready to pay due to the smoothening effect of the curve. The primary application of the moving curve is to provide the user (investor in this case) a visual aid to show the trend of the market. Another important aspect of this process is when the share price in the market tends to fall below the curve of moving average. This signal is important and should not be ignored especially when dealing with the long term calculation of the share prices. One of the main risks associated with this technique is that the investors tend to be whipsawed i.e. suppose, when the market falls below the moving average and a sell signal is created. But, then immediately or within a short frame of time, the share price tends to rise up again and thus generating a buy signal. By this case, the conclusion must be clear that this is a not so reliable method to invest i n the market. (Dagnino, 2001) This process of being whipsawed has been commonly prevalent in our case i.e. HSBC infrastructure company. This has happened 4 times i.e. when the share line crosses the moving average line from top, a sell signal was created but then all of a sudden or within a really short time frame, a buy signal was created. This further confuses the investors as the sell and buy signals are created back to back. One of the primary drawbacks of the moving average method is that it essentially tends to miss out the turning points i.e. when an important event has occurred due to which the share price of the share tend to fall immediately like fraud being visible, change in management, new project announcement or some other key information. Then, this method tends to immediately react to all this informations as the data in consideration is of 50 days and it takes a couple of days to react to this information. Or, if by chance, there is a bad news for the company and the market sees a sudden fall in the prices of shares, then the curve takes some time to react to this piece of information. A moving average trend method comes with certain drawbacks and its advantages. The method is very easy to calculate and too simple to understand. It does not require any special understanding of higher order mathematics or any special financial theory. But, one of the main drawbacks is that the method is not reliable as it uses the previous data available in the market. This method cannot be used to indicate the crests and troughs of the stock price in consideration. Since, the method deals with historically available data, so it can better are termed as a trend following indicator rather than trend indicator which it is supposed to be. Another factor in consideration should be the market behavior, i.e. if the market or a particular stock is behaving in a particular trend then this method might be of some use. But, if in case the market is moving without any particular trend, then this method can turn out to is a big failure leading to the collapse of investors portfolio or his inve stment.

Economics of Public Policy - 1186 Words

Daniel R. Lupu ECN 4010 2/18/2012 Economics of Public Policy Test 1 2. In thinking about a market economy and a regulated or planned economy, discuss the difference between â€Å"end-independent† rules or laws in society versus â€Å"end-dependent† rules or laws in society. In what ways would â€Å"end-dependent† rules or laws limit the use of knowledge by people in society, and how does â€Å"end-independent† rules or laws provide opportunity for people to use their different types of knowledge in society? (The distinction between â€Å"end-independent† and â€Å"end-dependent† rules or laws were discussed in class and in the article on, â€Å"Free Markets, the Rule of Law, and Classical Liberalism.†) The difference between â€Å"end-independent† laws and†¦show more content†¦(Don’t be afraid to use supply and demand diagrams in your explain and examples.) Usury Laws can lead to a black market in money lending. These regulations set by the government are intended to â€Å"protect† the citizens from â€Å"greedy† lenders by setting a maximum rate of interest, above which it is illegal to lend money. Lenders charge higher rates of interest to compensate for the amount of risk that can be associated with the transaction, risk being the likely hood of not getting paid in full. Once a usury law is put in effect there becomes a maximum rate at which the lender can lend money. With this maximum rate of interest some potential borrowers will be assumed too risky because it is not legal to charge the rate of interest to compensate the risk associated with lending. This leads to a smaller amount of money available to borrow from legitimate lenders, so often a borrower will turn to a black market lender who will illegally lend them money at a higher rate of interest. Often times the black market lender will use forms of persuasion s uch as bodily harm to the borrower and their family to ensure repayment. This clearly is more dangerous than high interest rates.

Causes And Consequences Of Malnutrition And Starvation Essay

In our society, there are many problems such as food price increases, less water available for food growth, desertification, malnutrition, starvation, climate change effects, and chemicals in the food. Many people think that the government has a solution for solving these social problems. There are many people out there that do not ignore these kinds of problems. They step up on their own to solve and make new changes for the sake of the society. Malnutrition and starvation are among the most important because there are so many people in this world that live without these basic needs; people go hungry and without food for days or weeks. Malnutrition and starvation are happening everywhere in this human society and in the animal world. Society should do more to increase food production, distribute food supplies, and plan for future stresses on the environment due to global warming.

Advantages Of IT In Courier Business Samples †MyAssignmenthelp.com

Question: Discuss about the Advantages Of IT In Courier Business. Answer: Introduction In the present age, the impact of information and technology is vividly visible in various business operations. The IT shapes the business operations in much simpler and enhanced manner thus raising the demand for incorporation of IT in business management. In the recent times, the advent of IT in the courier companies is witnessed. Incorporation of IT in supply logistics have greatly gave the courier business a new form resulting in the much organized package deliveries and sorting as well as maintaining a healthy communication with the sender and the receiver. This report mainly highlights the advantages of IT in courier business. Role of IT in courier companies: Enhanced sorting practices Incorporation of IT in the courier industry has greatly improved the sorting process of the packages and the deliverables. Rather than the traditional methods of sorting the letters advent of technology have given rise to the semi-automatic as well as fully automatic process for the sorting of packages. This automatic sorting process have minimized human labor, improved the sorting speed and also made the system less erroneous resulting in much optimized delivery system. The manual process of package handling and sorting is replaced by barcode technology. Each of the packages is assigned with a unique security code which helps in the identification of the shipment with the help of the scanning system (Hasnan, Noordin Osman, 2014). In the present date, the barcode technology is further evolved to resulting in the much efficient automatic labeling and sorting process. The courier companies are also incorporating the RFID technology for the sorting process. Although this technology is much costlier but it provides with several advantages compared to the age long barcode technology. RFID allows the reading of the codes from distance, which in turn enhances the security and reduces the chance of human error (Xu, 2014). Delivery process and transportation The delivery process is also optimized with the incorporation of IT by the courier companies. Software related to the delivery management is utilized by number of courier companies. Utilization of such specialized software and the courier tracking software has made the delivery process much simpler and efficient at the same time. The GPS tracking system have enabled the sender and the receiver to monitor their shipments in regular basis (Lin et al. 2014). Certain innovative transportation technologies are also in progress. Innovative vehicles such as drones, electric vehicles will be utilized for transportation of the shipment in the near future. Famous courier companies such as DHL and FedEx have already adapted this innovative transportation technology (Gruber, Kihm Lenz, 2014). Conclusion In conclusion, it can be seen that the IT have greatly brought improvement in the various operations of the courier industry. Incorporation of the technology has optimized the sorting as well as delivery process of the shipments. It can be seen that the GPS based tracking applications has enabled much accurate tracking of the goods by the customers. Other than this, the technology based sorting system has made the overall shipment process much efficient. References Gruber, J., Kihm, A., Lenz, B. (2014). A new vehicle for urban freight?

Attraction and repulsion in The Yellow Wallpaper and Dr Jekyll and Mr Hyde Essay Example

Attraction and repulsion in The Yellow Wallpaper and Dr Jekyll and Mr Hyde Essay Example Attraction and repulsion in The Yellow Wallpaper and Dr Jekyll and Mr Hyde Paper Attraction and repulsion in The Yellow Wallpaper and Dr Jekyll and Mr Hyde Paper Essay Topic: Dr Jekyll and Mr Hyde Literature The Yellow Wallpaper In Jeff Greens work on Plutos philosophies, Green states that The potential for tension and conflict in [the] dual desires of the Soul can be equated with the basic psychological phenomenon of attraction and repulsion (Green 5-6). The dynamic of attraction and repulsion in representations of the abnormal can be explored in both Robert Louis Stevensons The Strange Case of Dr Jekyll and Mr Hyde and Charlotte Perkins Gilmans The Yellow Wallpaper. In both of these texts, the principal characters experience clashing feelings of attraction and repulsion to what the reader would view as being abnormal. For instance, in The Strange Case of Dr Jekyll and Mr Hyde, Jekyll cannot help but feel intrigued by the exciting, dangerous life and character of Mr Hyde and in The Yellow Wallpaper the unnamed narrator1 similarly becomes fascinated by the figure she can see behind the wallpaper. It can be argued that both Jekyll and the Narrator feel attracted to the abnormal whilst the people around them feel repulsed by it. The Jekyll-Hyde dynamic in The Strange Case of Dr Jekyll and Mr Hyde may represent the dual desires of the human soul. Freud believed that the human mind is strongly influenced by thoughts and desires which we are not able to control and these impulses are often conveyed in our dreams. It is therefore possible to interpret the character of Hyde as Jekylls subconscious desire to be freed from his societys restraints. This subconscious desire of Jekylls is viewed by the characters around him as deviant and revolting. Although Jekyll also feels repulsed by Hydes grotesque and animalistic nature, he finds it impossible to curb his need to experience the life of a savage, uncivilised monster. Similarly, the Narrator in The Yellow Wallpaper experiences a conflict of emotions towards the wallpaper. It is clear to see that the Narrator takes an instant disliking to the wallpaper when she says, The colour is repellent, almost revolting; a smouldering unclean yellow (Perkins Gilman 4). However, she soon becomes fixated with searching for hidden meanings in the wallpaper. She believes that she can see a woman in the wallpaper who is struggling to break free and this seems to reflect the Narrators desire for freedom from the constraints placed on her by her husband and doctor. In The Strange Case of Dr Jekyll and Mr Hyde it is clear that Jekylls friends are repulsed by Mr Hyde from the outset. We can see this clearly in Enfields description of Hyde to Mr Utterson: He is not easy to describe. There is something wrong with his appearance; something displeasing, something down-right detestable. I never saw a man I so disliked, and yet I scarce know why. He must be deformed somewhere; he gives a strong feeling of deformity, although I couldnt specify the point. (Stevenson 12) Enfield states that although he detests the appearance and very being of Mr Hyde, he cannot articulate his reasons for feeling this way. It seems to be an instinctive reaction to this creature which symbolises everything that the prototype of a man living in Victorian society would not approve of. Although Jekyll is at first strongly attracted to the concept of a dual personality and having the freedom to rebel against society with anonymity, he too is soon repulsed by Mr Hyde when he realises the extent of his alter-egos corrupt nature: The powers of Hyde seem to have grown with the sickliness of Jekyll. And certainly the hate that now divided them was equal on each side. With Jekyll, it was a thing of vital instinct. He had now seen the full deformity of that creature that shared with him the phenomena of consciousness, and was co-heir with him to death [ ] he thought of Hyde, for all his energy of life, as of something not only hellish but inorganic. (Stevenson 74) Similarly to Hydes powers growing with the sickliness of Jekyll (Stevenson 74), as the Narrator of The Yellow Wallpaper continues to lose her sense of reality she too becomes more aware of her alter-ego, the woman she can see behind the wallpaper. However, she does not grow to hate this woman, but instead sees parallels between her own life of confinement and the female figures. As the Narrators madness deepens and progresses, she begins to see more women behind the paper. All of them appear to be lost in the torturing (Perkins Gilman 15) yellow pattern. With the appearance of more women, it seems that the Narrator now sees not only herself as being a victim of patriarchal standards of Victorian society, but in fact all women. Through her madness, the Narrator becomes repulsed by the restraints put upon women by society and instead becomes attracted to the abnormal idea of social rebellion. This echoes Jekylls initial rejection of ordinary Victorian life in favour of the adventures of Mr Hyde. As Jekylls friends are repulsed by the appearance of Mr Hyde, the Narrators husband is repulsed by the concept of sexual equality. Instead, he is a firm believer of men having complete control over their wives lives. He treats the Narrator like a child, referring to her as a little girl (Perkins Gilman 14) and choosing to place her in the nursery at the top of the house (Perkins Gilman 4). John undermines the seriousness of his wifes condition when he assures friends and relatives that there is really nothing the matter with [her] but temporary nervous depression a slight hysterical tendency (Perkins Gilman 1-2). We can see that John ignores his wifes suggestions for activities when the Narrator tells us that she has a scheduled prescription for each hour in the day and that John takes all care from [her] (Perkins Gilman 4). It is worth noting that the Narrator does not say that her husband takes care of her, but instead implies that he takes all control out of her hands. This proves that John thinks it natural for men to have power over women and it would therefore be possible to argue that men like John would have found the idea of the New Woman utterly abhorrent. In The Strange Case of Dr Jekyll and Mr Hyde, we can see Jekylls initial attraction to unleashing his subconscious needs in a letter he writes to Mr Utterson which explains the repression of his egotistical desires which society would frown upon: The worst of my faults was a certain impatient gaiety of disposition, such as has made the happiness of many, but such as I found it hard to reconcile with my imperious desire to carry my head high, and wear a more than commonly grave countenance before the public. Hence it came about that I concealed my pleasures [ I stood already committed to a profound duplicity of life. (Stevenson 60) When reading the text closely, it is possible to state that Stevenson suggests that within everyones personality there lies a Mr Hyde, a character full of cravings which are not influenced by social beliefs and standards but are instead primitive and innate. When Jekyll admits to having repressed and unsatisfied desires, his confession leads the reader to realise that everyone is forced to hide certain cravings in order to remain socially acceptable: Many a man would have even blazoned such irregularities as I was guilty of; but from the high views that I had set before me, I regarded and hid them with an almost morbid sense of shame (Stevenson 60). Jekylls feelings towards suppressed desires and attractions are resonated by Lanyon when he admits he has since had reason to believe the cause [of his hatred of Mr Hyde] to lie much deeper in the nature of man (Stevenson 56). Both Utterson and Enfield can be classed as exemplary Victorian male figures, yet Stevensons insinuation that there is a secret Hyde-like character within these two men can be detected from the opening of The Strange Case of Dr Jekyll and Mr Hyde. The reader is told that Utterson had an approved tolerance of others; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds (Stevenson 7). Despite disapproving of anti-social behaviour, at times Utterson feels jealous of those with an ability to rebel against convention. The reader can identify the Hyde-like aspect of Enfields personality when Hyde has trampled (Stevenson 9) over a young girl. Enfield wonders how best to punish Mr Hyde for this offence when he says, Killing being out of the question, we did the next best (Stevenson 10). It is possible to argue in that these men find Hyde repulsive because their subconscious mind is able to identify him instantly as the savage within. We could apply this theory of recognition in the subconscious to the character of John in The Yellow Wallpaper. Perhaps his disdain at the Narrators behaviour is due to a similar part of his personality which he hides from others by using his position of power over his wife. It is also possible to argue that the Narrators initial hatred of the wallpaper is due to a subconscious recognition of the woman she sees behind it as sharing her suppressed wishes. The Narrators attraction to the wallpaper quickly turns into an obsession and as she descends into madness she becomes more conscious of her subconscious desire for freedom. On the surface the Narrator accepts her husbands power over her. However, at the end of the novel she appears to be taking her frustration caused by her husband out on the wallpaper. She claims that the pattern slaps you in the face, knocks you down, and tramples upon you (Perkins Gilman 16), suggesting that she is forced to study the wallpaper and, like Jekyll, cannot control her attraction. By the end of the novel, the Narrators fixation with the woman she can see behind the wallpaper has grown to the extent that she believes herself to have also been trapped behind it. We can see this when she exclaims, Ive got out at last [ And Ive pulled off most of the paper, so you cant put me back! (Perkins Gilman 26) For the Narrator, her abnormal behaviour has given her a sense of freedom. Despite this, the frequent use of the word creeping (Perkins Gilman 24) throughout The Yellow Wallpaper suggests a fear of being caught and also gives the impression of submission. This shows that even though her subconscious desires are becoming apparent to her, the pressures of society are still controlling the way she views them and she realises that her feminist ideals are taboo. When John realises that his wife has undergone a stereotypically masculine task of destroying the wallpaper, he is instantly feminised by his overtly feminine reaction of fainting: Now why should that man have fainted? But he did, and right across my path by the wall, so that I had to creep over him every time! (Perkins Gilman 26) When John faints, the Narrator has at last gained power over her oppressive husband and the fact that she repetitively creeps over his body emphasises her new found authority. It also highlights Johns inability to control his wife who, though mad, is now mentally liberated. Over all, it is possible to state that in The Strange Case of Dr Jekyll and Mr Hyde and The Yellow Wallpaper, the abnormal was seen by Victorian society as a desire to rebel against traditional values. One could also argue that the dynamic of attraction and repulsion with regards to the abnormal is a complex and contradictory matter as the conscious mind which is influenced by external sources often suppresses subconscious wishes. Jeff Green explains in his work entitled Pluto that people often feel repelled by what they feel attracted to, because the attraction may directly threaten the existing nature of their reality (Green 45). At the end of The Strange Case of Dr Jekyll and Mr Hyde, Jekyll explains in his final letter to Utterson his beliefs in the division of the human personality: man is not truly one, but truly two. I say two, because the state of my own knowledge does not pass beyond that point [ ] It was on the moral side, and in my own person, that I learned to recognise the thorough and primitive duality of man; I saw that, of the two natures that contended in the field of my consciousness, even if I could rightly be said to be either, it was only because I was radically both [ It was the curse of mankind that these incongruent faggots were thus bound together. (Stevenson 61) Jekyll realises that through his experiments he has created a monster and has lost control of his life as Henry Jekyll as we find out that the potion he has been using only worked due to an impurity in the original salt. As he writes to Utterson, he accepts his fate to become Hyde permanently and he wonders, Will Hyde die upon the scaffold? Or will he find the courage to release himself at the last moment? (Stevenson 76). The tone of this concluding chapter of Stevensons novel is ominous with references to death and evil. The conclusion of The Yellow Wallpaper contrasts greatly with Stevensons ending as it is playful and almost comic. As the Narrator in The Yellow Wallpaper loses her sanity, her writing becomes more coherent and she seems to have found a form of self expression in her journal. The Narrator has found freedom after her battle with the conflicting forces of repulsion and attraction with regards to the wallpaper whereas Jekyll is doomed to remain forever as the evil half of his character, a punishment for his tampering with nature.

As You Like It by William Shakespeare Essays

As You Like It by William Shakespeare Essays As You Like It by William Shakespeare Essay As You Like It by William Shakespeare Essay Essay Topic: As You Like it A. The Forest of Arden at first glance, is a country life of arcadian contentment, rustic tranquility, a golden world in all its glory. A place to while away the hours like, the old Robin Hood of England. And so is portrayed and backed up with the seemingly content Duke Senior and his merry men. Duke Senior praises the effects of Arden on him stating its different virtues in the forms of a healer, a nurturer and a counselor. Its effects on the people who come from the court are drastic if not almost instantaneous and bring out some unique aspect of their personality which is not yet known. For Oliver and Duke Frederick, there is an almost impossible change for the better as Duke Frederick is converted both from enterprise and from the world. Furthermore the previously non-existent bond of brotherly love is created between Orlando and Oliver which in turn leads to Olivers conversion. In Rosalinds case, the Forest provides a source of unimaginable freedom to express herself without the barriers of court conventions (though this may be the result of the disguise alone). It is the place where she can love Orlando without the strict rules and regulations that governed her previous residence. Likewise Orlando is provided an escape from his brother oppression where he can leisurely convey his love for Rosalind. On the contrary, the Forest can divert from the pastoral convention as you peer into its harsh realities and its ill-effects on its limited population. Duke seniors opening speech was in reality an attempt to hearten his co-mates and brothers-in-exile. Although thinly veiled with heartening comments about the seasons icy fang as a counselor and the churlish chidings of the winters wind as a sweet use of adversity, it still remains that it is an icy fang and the winds do bite and blow upon his body. Although, the Forest of Arden does display salutary qualities when it comes to the characters outlooks and personalities, it is still a source of discomfort and physical pain, a barren desert. Another characteristic that is associated with Arden is its sense of camaraderie and of an egalitarian society. Where Duke Seniors court becomes a circle of brothers, where Oliver and Orlando become brothers once more, where Duke Frederick learns humility. But this is not completely so as we see an example of a cruelty and neglect in Corins master. Moreover Celia, a lively character in the opening act of the play progressively loses her energy as she loses her friend (Rosalind) to forest follies. The forest also comes across as primitive. This is proven by the venison of the forest. The poor dappled fools are subject to cruelty of the most primitive kind in their own dwellings. In conclusion, the Forest of Arden is in fact an ideal place for recuperation and introspection in the sense that many of the characters achieved transformations of sorts. However it is seen (with a few exceptions), that the characters of the play are unwilling to stay in the forest when presented with the alternative of the court. Therefore, the forest may be ideal, but is a short-lived idealness.

Participant Observation Assignment Essay Example | Topics and Well Written Essays - 1000 words

Participant Observation Assignment - Essay Example The research questions formulated in this paper are mainly based on empirical observation, that is, information gained by means of watching, experiments or by performing some research study. This field work has been conducted on August 6, 2009 during 10.30 AM and 12.35 PM. The journey for observation assignment started from Hudson, NY station and ended at NY-Penn Station. The train selected for this observation assignment is Empire Service-Eastbound train (which is running Mondays thru Saturdays) whose number is 280. The source station of this train is Niagara Falls, NY, the departure time from this station is 3.45 AM and its arrival time in the destination station New York, NY-Penn Station is12.35 PM. Subways in New York are the fastest way to travel around the New York City. It is very difficult for the fresher to travel through New York subways. If one is not careful, then one would find it very difficult to reach the destination. If one does not know about the rules and regulations that need to be followed in the subways, then one would find it hard to travel through the subways. Here, it can be observed that some people are asking others about the direction, or the route one needs to take for reaching specific destinations. People in New York help others to sort out their problems in very friendly manner. Another important thing about people in New York is most of them are confused as to which direction they need to go to reach their destination. In the platforms, it is observable that all sorts of people are present such as teens, middle aged people, old aged people, families etc. Some people are looking on the map which is placed near the entrances; they are sorting out the ir doubts themselves without asking to anybody. By observing their facial expressions, it may be concluded that they are not so clear about whether they have gleaned what they needed to know. Time is 10.15 AM.

Answer dq 7 Essay Example | Topics and Well Written Essays - 500 words

Answer dq 7 - Essay Example He built a relationship which was firm and tackled it enthusiastically. He set an example by personally adopting all possible traits to be a fruitful leader which motivated his followers and ultimately it is understood that if a company flourishes, workers flourishes. One of the main points is, a leader who has a charisma can understand the issues that would arise with his new plans, and therefore he remains ready to guide, help and accommodate his followers well. (Raelin 2003) explains that all leadership styles have something good to be adopted; therefore charismatic leadership can walk parallel to transformational leadership because charisma spreads over groups and transformational leadership supports it well. To attract followers, we studied well in our last discussions that currency exchange and implementation law of reciprocity can be good deal to make followers work accordingly. Different leadership styles are interlinked and therefore in my last article I wrote that theorists claimed that leadership is the most complicated phenomenon to be completely implemented. (Bascal and Associates) narrates that Charismatic leaders have an ability to communicate on strong emotional grounds and can convince, support and make followers understand the requirement of a desired plan, John F. Kennedy who is referred as a charismatic leader serves perfect example. He convinced people to remain strong and fight back for their rights during crucial time of Civil War. I agree with the point raised that setting charisma and vision into two different entities can simplify things to be understood. Vision is embedded in charisma and therefore a charismatic leader is able to convince people to understand his vision and work together to accomplish it, while remaining on a powerful emotional ground. Strong leadership is about executing the plans firmly and charisma makes it more fascinating

Mix Design Procedure And Principles Engineering Essay

Mix Design Procedure And Principles Engineering Essay 1. Introduction In the following coursework we are going to take look at the steps that must be taken into account for performing a concrete mix design. When we talk about mix design, we are going to deal with two categories of property requirements: one category specific for fresh concrete (fresh properties of concrete); and another category specific for hardened concrete (Neville 1995). The aim of this coursework is also to analyze the properties of the freshly formed concrete due to the design performed, and not of the hardened concrete. As outlined in Lecture 2, the two types of property categories are not independent from one another, more likely they are directly linked, and failure in compliance with fresh properties will lead to poor concrete quality in hardened state. Basically, concrete mix design is performed by a careful selection of quantities for concrete ingredients with the aim at producing cost effective concrete having a minimum set of properties such as: workability, compressive strength and durability (Neville 1995). For the purpose of this coursework, we are going to design concretes which will contain mixes of classic ingredients like ordinary Portland cement as a bonding material and, either 100% Gravel or 100% Recycled Aggregates, as a filler material. Also, we are going to design mixes by replacing a part of the Portland cement with cementitious materials such as Silica Fume (10% SF) or Fly Ash (30% FA) and the reason of using these fine materials is that they will limit the amount of energy consumed in the mixing process, which ordinary Portland cement is not capable of doing. Having 4 types of concrete mixes, we are going to deal with different properties between these mixes, each set of concrete properties being governed by the properties of the materials used. For example, recycled aggregate presents an increase in porosity compared with gravel, so it is no surprise that concretes with recycled aggregates will demand more water content than ordinary, natural aggregates. Eventually the workability will be affected by the higher water demand (Dhir et al. 1998). Also, as comparison between the effects on concrete determined by SF or FA we must state that concretes with FA will experience a decrease in water demand, reduced bleeding and good cohesiveness, while concrete with SF will bring an increase in water quantity. Because they were 4 different types of mixes to be designed and tested in the lab, 4 groups, each designing their own mix, were created. Our group had the task of performing the mix design for the 10% SF mix and this was done according to BS 1881: Part 125: 1983 Testing concrete Methods for mixing and sampling fresh concrete in the laboratory. Silica fume has certain characteristics that make the handling, when we make the mixing of components, to be a difficult task. This is due to the small particle size and high fineness of the silica fume, so slurry is going to be prepared, by combining silica fume with water, when performing the mixing and also we should make sure that the slurry will be fully dispersed into the mix. By having a high fineness, the SF particles will demand a large surface to be covered with water, bringing an increase in water demand as stated above. Mixes having silica fume as ingredient will give us high performance concretes., and the presence of SF in the mix design process will not only affect the quantities of the mix proportions to be used as ingredients of concrete, but also will lead to an improvement in the fresh properties of the concrete like: high cohesiveness, little to none bleeding, suitable for pumping (Neville et al. 1995). In the lab, after we performed the mix, we made some tests in order to have quality control over the product: Slump Test, according to BS EN 12350-2:2000 Testing fresh concrete Part 2: Slump test, to determine the workability of the concrete and the Plastic Density Test, according to BS 12350-6, 2000 Testing concrete Method for determination of density of compacted fresh concrete, to determine the actual plastic density of the concrete. 2. Mix Design Procedure and worksheets. 2.1. Procedure principles. It should be stated that this method is not an exact method of quantity assessment mainly, because of the variability of the parameters affecting the constituents of this procedure. Trial mixes are made with the purpose of guessing which combinations of ingredients will be suitable for the desired concrete properties and we can modify these mixes to correspond to our requirements (Neville 1995). 2.2. Description for performing concrete mix design. Mix design follows several steps according to BRE Report 331, in which the flow chart of steps takes into consideration all parameters of the mix constituents and also shows us how they are linked together. The results of the computation are going to be written on a Concrete Mix Design Form. For performing this procedure a number of initial specifications must be given, specifications which include: Cement type 52.5 N; Aggregate type Gravel; Maximum aggregate size 20 mm; Fine aggregate grading 44%; Aggregate relative densities 2600 kg/m3; 10% Silica Fume 0.45, 0.6 and 0.75 w/c, 180l/m ³ water content, Slump of 30-60 mm (achieving S3 with SP) The stages which govern this procedure, as specified in BRE Report 331 are: Stage 1 water/cement ratio Stage 2 water content Stage 3 cement content Stage 4 total aggregate content Stage 5 fine aggregate proportion Stage 6 trial mixing Having the 3 free-water cement ratios, the slump and the maximum size of the aggregates given, we can skip the first stage and the amount of water needed can easily be determined. As we can see, 3 mixes will be prepared for which we can determine the amount of bonding material needed if the quantity of water is known. In this total amount of bonding material, 10% is Silica Fume, while 90% is ordinary Portland cement. In stage 4 we shall determine the total quantity of aggregate present in the mix. Because we have the grading of the fine aggregate, we can determine the quantity of the coarse aggregates by subtracting from the total quantity of aggregate the fine aggregate quantity. From the total quantity of coarse aggregate we know that 1/3 is for 10 mm Gravel and 2/3 for 20 mm Gravel. After we have determined all the mix proportions, we have to make specimens from the resulted concrete mix, specimens which will be subjected to different tests and conditions in order to determine the suitability of hardened concrete. These concrete specimens result from trial mixes for which batch weights are computed for a batch size of 0.02 m3. One aspect hasnt been discussed so far: the use of admixtures in the concrete mix design. Admixtures are regarded as secondary ingredients of concrete, and not in the same class of importance like water or cement. There are different types of admixtures, depending on their effect on concrete, and, also their use is regarded from an economical and an increase in concrete quality point of view. For the purpose of our assignment, the admixture type which we are going to use is Superplasticizer (Glenium 51) and the British standard that regulates and controls their use is BS 5075: Part 3: 1985. Superplasticizers are water reducing admixtures, and their effect on concrete is related to an improvement in fresh properties, mainly an increase in workability. 4. Batch quantities allowing for absorption. 4.1. Porosity, Absorption and their link. Porosity and absorption are aspects concerning the aggregates, so the following discussion will take into account the way in which the presence of pores will affect the concrete. There are 2 types of pores: internal and external pores, which vary in size- the external pores, can even be seen sometimes with the naked eye. Because of its viscosity, cement paste cannot fully cover the pores of the aggregates, but water is able to do that, which eventually will lead in an increase of water demand (Neville 1995). It might seem that because its only related to aggregate, porosity and absorption will not affect concrete, but lets not forget that the weight of aggregates represents approximately 75% of the weight of concrete. Also, by doing the mixing of concrete in the lab, the moisture content of the aggregates decreases, so an adjustment for absorption of aggregates must be done: we fully dry the aggregates in an oven, after which we put the aggregates in water, for 24 hours. An increase in weight occurs, meaning that all the pores are fully saturated (Neville 1995). The absorption is expressed as a ratio between the moisture content increase observed in the dried aggregates to the mass of the dried aggregates. The following absorption values for aggregates are used for our designed concretes: Gravel 5/20 1.0% Sand 0/5 0.5% RA 5/10 3% RA 10/20 4% 4.2. Adjustments for absorption. The adjustments for absorption, determined in accordance with BS 812: Part 2, are performed on the aggregate types which are going to be used in the mixture. The aggregates which we are going to use for the 10% SF mix concrete are: sand 0/5 and gravel 5/20. The method allows computing the additional quantity of water required for absorption by the following formula: Material batch weight (kg) x absorption value (%) = additional water required Having found the additional water quantity, the adjustment for absorption of aggregates can be performed by: Aggregate batch weight (kg) absorbed water (kg) = adjusted aggregate batch weight 5. Mixing procedure and tests carried out in Lab 1. 5.1. Mixing procedure. Relevant Standards: BS 1881: Part 125: 1983 Testing concrete methods for mixing and sampling fresh concrete in the laboratory. The mixing procedure is the combining of all concrete ingredients, with the purpose so that the aggregates surface is covered by cement paste, and it follows 2 steps: a) Sample preparation; b) mixing. At the previous topic, the adjustment of aggregates for absorption was explained. Its one of the requirements for the sample preparation step, and was the last one that needed to be carried out before the proper mixing of all concrete ingredients can be performed. When discussing about sample preparation, we also must take into account that we should produce at least 10% more quantity of concrete than the required quantity for the tests that have to be done; Follows a series of tasks: initially, the aggregates should be added in the following order: coarse aggregate, fine aggregate, sand after which we mix for 30 seconds. 1/2 of the water quantity must be added next, mix for another minute, after which we thoroughly mix by hand. Water absorption by the aggregates takes place when we leave covered the mixer for 8 minutes. Silica fume is mixed with water for 1 minute before adding it to the mix, after which we add the cement and mix it for 1 minute. We clean the paddles; we add the remaining water and superplasticizer and mix for other 4-5 minutes, after which we ensure homogeneity by mixing the sample by hand. 5.2. Tests carried out in Lab 1. Before starting the discussion about what tests must be done, we should note that all these tests on fresh concrete should be carried out within 15 minutes of mixing. Two tests will be done: slump test and plastic density. After the tests are carried out, we must put the used concrete in the mixer and mix for other 30 seconds. The Slump test has the aim of analysis of the workability of the fresh concrete, and it regulated by BS EN 12350-2:2000 Testing fresh concrete Part 2: slump test standard. When performing this test we must have some basic equipment: a slump cone with foot rests and a metal rod (16 mm diameter, 600 mm long). First, we must moisten the slump cone, after which we pour the concrete in the cone, while it is hold firmly into position. The pouring of the concrete must be done in 3 equal layers which are tamped 25 times with the steel road. The excess of concrete at the top and around the slump cone is removed, after which the cone is removed, inverted and placed next to the slumped concrete in order to enable us to measure the vertical distance from the top of the cone to the highest point of the slumped concrete. The measured vertical distance has to be reported for the nearest 5 mm, and shows us the nature of the slump that we deal with: true, collapse and shear slump. Fig. 5.2: True, shear and collapse slump (Neville et al. 1987) If the shear or collapse of the sample concrete occurs, we must perform the slump test once again. Plastic Density is determined on a compacted concrete sample in the lab, and is regulated by BS 12350-6, 2000 Testing concrete Method for determination of density of compacted fresh concrete standard. When performing this test we must have some basic equipment: 10 liter steel container (200 mm internal diameter, 320 mm internal height, and 4 mm wall thickness), vibrating table and 300 mm steel rule. The test is carried out as follows: we measure the mass of the empty container after which we measure the mass of the container filled with 10 liter of water. The concrete is poured in the empty container, in six equal layers which will be compacted on the vibrating table and the excess concrete at the top will be removed. We record the mass of the container with the concrete in it; we return the concrete to the mixer and clean the equipment. The computation can now be performed with the following formula: Plastic density, D = m / V Where, m = mass of concrete in container (To the nearest 10 g) V = volume of container = mass of water in container (from calibration) /1000. During the mix design we have found a plastic density for each water-cement ratio. Having found that plastic density, the new lab computed plastic density must not differ by more than  ±20 kg/m ³ then the actual plastic density (mix design). 7. Yield: corrected mix proportions and differences between design/plastic and volumetric method. Because in the mix design we have taken into account only those parameters that have a major impact on concrete characteristics, and we disregarded those that have a minor role, some errors might occur during the mix design. Such errors might include: faulty maneuvering of concrete ingredients, errors in performing the mixing procedure. These errors are visible when the total weight of the concrete ingredients is different than the lab computed wet concrete density (plastic density). Having computed in the lab the actual plastic density of the mix, we can make corrections to the mix proportion weights so that some of the residual errors might be able to be corrected. One of the ways by which this can be done is adjusting for yield. Yield is the ratio between the actual density and the total density, and the adjustment is performed by multiplying this ratio with the weight of each constituent, giving us corrected mix proportions. As an example we shall perform the correction of the mix proportions for the 0.45 w/c ratio mix: During the mix design we have found that the wet density of concrete (plastic density) is 2380 kg/m3. Cement+10% SF 360+40 kg/m ³ Water 180 kg/m ³ Sand 650 kg/m ³ 10mm Agg 385 kg/m ³ 20mm Agg 770 kg/m ³ TOTAL DENSITY 2385 kg/m ³ ACTUAL PLASTIC DENSITY 2410 kg/m ³ (tested in labs) The correction is done with the following formula: Corrected = (Actual density/ Total Density) x each constituent = 2410/2385=1.0105 Cement+10% SF (365+40) kg/m ³ Water 180 kg/m ³ Sand 655 kg/m ³ 10mm Agg 390 kg/m ³ 20mm Agg 780 kg/m ³ CORRECTED DENSITY 2410 kg/m ³ Another method by which we can adjust the mix proportions is the volumetric method. The main feature of this method is that, when performing the adjustment, we will take into consideration the particle density of each constituent taking part in the mix design. We shall also make an example for the volumetric method of correction of mix proportions. Cement 360 kg/m ³ / 3150 kg/m ³ = 0.114 SF 40 kg/m ³ / 2000 kg/m ³ = 0.02 Water 180 kg/m ³ / 1000 kg/m ³ = 0.18 Sand 650 kg/m ³ / 2600 kg/m ³ = 0.25 10mm Agg 385 kg/m ³ / 2600 kg/m ³ = 0.148 20mm Agg 770 kg/m ³ / 2600 kg/m ³ = 0.296 ACTUAL 1.008 THEORETICAL 1.0000 The correction formula: Correction factor = (Theoretical/Actual) x each constituent = 0.992 Cement 355 kg/m ³ / 3150 kg/m ³ = 0.1133 SF 40 kg/m ³ / 2000 kg/m ³ = 0.020 Water 180 kg/m ³ / 1000 kg/m ³ = 0.180 Sand 645 kg/m ³ / 2600 kg/m ³ = 0.2474 10mm Agg 380 kg/m ³ / 2600 kg/m ³ = 0.1461 20mm Agg 765 kg/m ³ / 2600 kg/m ³ = 0.2932 ACTUAL 1.0000 THEORETICAL 1.0000 The main difference between the two methods which we have shown is that the yield method requires computing the lab plastic density, and comparing it to the plastic density taken into account in the design phase of the mix, while for the volumetric method is not necessary to make that extra effort in order to make the adjustment. As far as to which method is more appropriate to be used, from a first look at our example, we can consider that the volumetric method is more appropriate, at least from an economic point of view, because the adjustments made gave us smaller weights of materials than the adjustment for yield weights. But my opinion is that the plastic density method is much more appropriate to be used, because its more reliable, and you have a superior certainty about the elimination of the errors that appear in the mixing phase and also a better control of quality of the concrete. 8. Comments on fresh properties. The discussion about the fresh properties of concrete might seem to be not as important as the hardened concrete properties from a structural point of view, but as we have previously noted, there is a direct link between the two types of properties: for example the strength of hardened concrete is greatly improved when a sufficient compaction of the fresh concrete was established (Neville 1995).The objective of this discussion is to see the degree by which different concrete components affect the fresh properties of concrete, and we shall do this by comparing the mixes presenting silica fume, fly ash and recycled aggregate with the ordinary Portland cement mix (100% Gravel). The influence of aggregate type: by comparing the fresh properties of the 100% Gravel mix and 100% RA mix. Due to the fact RA have a higher porosity, a larger amount of water is needed in the mix which will eventually affect the workability of the fresh concrete. Because we have considered an absorption value for RA which was too high (RA density was larger than 2400kg/m3), the RA mix presented collapse slump, thus poor workability, also a slight bleeding, and segregation of the concrete constituents is present, leading to a poor cohesiveness. In the 30% FA and 10% SF mixes we have used as aggregate, gravel, so the influence of aggregate type on fresh concrete is the same in all 3 mixes, the only differences occur from the influence of other parameters. The cement type that we have used was either ordinary Portland cement (CEM I 52.5 N) or composite Portland cement, by combining the Portland cement with a cementitious material like silica fume or fly ash. As we can see from the comparison of the composite Portland cement mixes with those having only Portland cement, the 30% FA mix presents no bleeding or segregation of materials, a good cohesiveness and finishability. Fly ash reduces the amount of water to be used in the mix, having a similar effect as a superplasticizer, so at larger water cement ratios we have collapsed slump, poor cohesiveness, and a slight bleeding and segregation is present but the compactibility and finishability is still good, making it suitable for pumping . That is not the case with silica fume. Silica fume increases the water demand, and generally the mixes with silica fume present good cohesiveness, no bleeding and segregation, true slump giving us a good workability. The usage of both silica fume and sup erplasticizers has a good effect on concrete. The amount of fine material is directly linked to the cost of both silica fume and fly ash. The cost of production is quite large, so the use of silica fume and fly ash is no longer a cheap, viable solution for Portland cement replacement. As far as their consequences on fresh properties, for the 100% Gravel mix, at lower water-cement ratios we deal with a stiff mix, having less finishability and compactibility than when the amount of Portland cement is decreased, while the cohesiveness, lack of bleeding and segregation is kept the same on all mixes. We could use higher amounts of SF and FA but after a certain amount they cease to have any effect on the fresh properties of concrete. The water-cement ratio is one of the main factors affecting the concrete fresh properties, simply because water and cement are two of the main constituents of concrete. In the 100% RA mix, because of the use of RA, it was necessary to have a higher amount of water than in the other 3 mixes, which in return gave us a poor cohesiveness, a collapsible slump resulting in a poor workability. Also some segregation and bleeding was observed, which was not present in the other mixes. As a general rule, when the w/c ratio is decreased, the ratio between the other concrete constituents is kept constant, so the workability increases (Neville 1995). The SP amount required for workability. Superplasticizers greatly affect the slump of a mix. For the 100% Gravel mix we used approximately 0.12% amount of superplasticizers for all w/c ratios, which gave us a true slump. When we look at the 30% FA and 10% SF mix we can see that we have increased the amount to about 0.31% which gave us a collapse in slump when we used FA, so too much SP, and a true slump for SF, because SF works much better with SP compared to FA. 9. Conclusions This coursework has to be looked at as being divided in two parts: a part about the concrete mix design and establishing all the mix proportions of the concrete constituents and another part relating to the fresh properties of the resulted concrete. During this coursework we have successfully designed 4 types of concrete, and as a result the fresh properties of the 4 concretes were individually established and assessed. The mix of concrete ingredients, the determination of slump and the computation of plastic density were all done in the lab according to the relevant standard governing each task. The designed concrete types were: 100% Gravel, 100% RA, 30% FA and 10% SF. By assessing the concrete fresh properties we have seen which mixes had problems and were not suitable for using on site, but excluding some problems found (a high amount of superplasticizer than the one needed in the 30% FA), in general the mixes presented good workability without segregation or bleeding, were suitable for pumping so they could be used on site, in real conditions.

double standards and church and state :: essays research papers

Double standards are when there are a set of rules for one set of people and another set of rules for another set of people. How dose this pretain to the seperation of church and state do you ask? Relgion in school is my answer. We as students are not supposed to preach our religion in school. But along with that there is also a section within each of our text books that is all about religion. Teachers tell us that those are only classics and we have no reason to complain. Then they expect and incourage us to discuss about the a religiose storys within our text books. This act makes many students religios or not uncomfortable. I know this because I have asked several students how they felt about the issue. One student had told me how he had to go through a discussion an atheist student had brought up about his thoughts and beleifs on religion. This made the student i asked very uncomfortable and angery at the fact that the atheist student was preaching , as my friend felt, against my friends religion to his class. This act of discussing, as the teachers put it, made this sertain student very angery at the fact that the teacher can sit there and let the student preach against someones beliefs. Knowing that many people, not only the student I spoke to, believed in what the atheist was aposeing. So my friend was not the only one angery at that discussion and not showing it, but many were. This issue of discussion also gose other ways. For example, say a Jewish student was assigned ,along with the rest of the class, a religious short story on a Christian belief. When he returns to the school and the teacher starts a discussion on the story. The teacher explains the back ground of the religion and gets into great detail . To this Jewish student this sound alot like preching the Chrisian beliefs to the class. There could also be a different student in the class that had the same problem and he or she just happens to be a Buddist, Muslim, Mormand, ect. This explaining of the Christian religion could sound like preching to anyone with a different religous back ground. Anyone that can make a student quit reciteing the Pledge of Allegiance every day just because of the statement, "One nation under God".

Cyberspace and War Essay

Reading the highly interesting essay entitled â€Å"Navigating the Cyberspaces of Virtual War† presents to us the reasons why movies like The Terminator movie series are no longer works of fiction as written by an over active imagination. The reality is that science and computer technology have reached that point in the evolution of the systems that both the real and imagined reality of everyday lives, problems, and in this case, world wars, can now seamlessly interact and allow human beings to become active participants in the situations without really posing any physical dangers to the themselves. We have to admit that violence is an inborn characteristic of humans regardless of age, gender, and capability. But, man is afraid of the real repercussions stemming from any act of violence. Nobody in his right mind would put his own life on the line if he can find a way around it. This is the problem that presented itself to the public the day that man found a way to involve themselves in virtual war games. It is true that soldiers must be well trained and versed in handling their weapons and be so familiar with their combat zone that they can patrol the area blindfolded. For the military, the applications of virtual war is endless and a fantastic training tool that limit’s the number of casualties in the field. The problem is that the virtual war games were commercialized and sold to the public for home entertainment. The end result of the virtual gaming world was the desensitizing of mankind. Virtual Reality turned into an actual reality for some wherein nobody ever actually got hurt or died. It redefined violence for the participants and made it seem alright to blow each other up because â€Å"It’s just a game†. However, the developers of such games neglected to consider the psychological effect of the game on an ordinary person. A soldier would eventually have to deal with the reality of his virtual training and deal with actual loss of lives from both friendly and enemy fire. For the common man who merely plays the game and does not need to experience the actual loss, it instead gives him a thrill that sometimes pushes him to emulate the game in a real life setting. Early on, I mentioned that the Terminator movie series has now turned into a reality. This is a truth that can be seen because of the way cyberspace and war have turned battles into situations fought by remote control from the comfort of the soldier’s home base using highly intelligent computer systems that are capable of deciding upon what kind of weapons to use depending upon what their sensors data transmits to the onboard computer. But, what if the onboard computer develops a problem that causes the machine to turn upon its remote operators? What if Artificial Intelligence turns into Real Computer Intelligence? Are we prepared for such repercussions? Our computer developers and scientists have turned computers into almost fully independent machines that can function and decide its own actions in times of war. Good for the soldier because he won’t have to risk his life on the battlefront. Bad news for the rest of us because cyberspace is filled with computer hackers who would love to be able to gain the bragging rights to being that one person who took down a whole satellite system or took virtual / cyberspace enabled control of a real online defense system thereby gaining control of the military fighting machines for his own whims. Cyborgs are not that far off in development either. A perfect fighting machine, no feelings or logic, just a follower designed to eliminate the enemy as per preloaded mission objectives. The question is, how prepared are we to unleash such forces into reality? What safeguards are in place within cyberspace to protect us from the potential disasters cyber wars and technological advancements in cyberspace could bring upon mankind? The internet, online war gaming, television, and newspapers all present us with the realities of war while we are still far removed from the actual situation. I believe that if the world is to know any sort of peace, such virtual technologies should be limited to only military applications and not be allowed for commercial purposes. There is no need to feed the violent tendencies of man. Instead, a separate virtual reality should be developed for the common folk where we can practice solving political tensions through discussion and treaties instead. Leave the virtual fighting to those who are trained to really handle such situations. Cyberspace and war do not have to become any sort of reality for mankind simply because all it will bring about is our own self destruction in both virtual and actual reality.
