Investigation: Water Scarcity in Australia

Investigation: Water Scarcity in Australia Students Name: James Yu Abstract This paper indicates the water scarcity and water pollution in Australia. These two things can be serious problems in Australia because it is so major a food exporting country. The sources we use as references are all websites and two scientific paper. The solution for these two water issues are cloud seeding and enacting some laws which forbid people from throwing plastic casually. However, just clouding seeding probably can work efficiently if Australia have sufficient capital to conduct these experiments. The limitation of this paper is source availability, all what I can use is Internet because it is tough for me to find books on this topic in English version. 1.0 Introduction This scientific paper indicated several causes of water scarcity and water pollution in Australia, and also provided some solutions of solving this issue. Australia is one of the most developed countries all over the world, however, this country got a severe water restriction. One of the most underlying causes is sea surface temperature (SST). In the south of Australia , the SST is lower than average. This signified that there was few evaporation of water, caused atomospheric desiccation, and led to limitation of raining (Sea Surface Temperature (SST) Contour Charts 2013). The cause of water pollution in Australia was polyolefins, which accounts for 52% of plastic production and were used for manufacturing throwaway packaging (Schneider J 2013). These plastics could spoil our food web and ecosystem. Australia mostly gather water from raining and a large proportions of water was used for agriculture, because Australia was a major food exporting country (M. Ejaz Qureshi, Munir A. Hanjr a, Ward J 2013). Our hypothesis was Australia could conquer water scarcity and water pollutionif they develop cloud seeding and enact some regulations on environmental protection.

Reference: http://www.wentworthgroup.org/docs/Chartres__Williams.pdf 2.0 Methodology The source of this scientific paper was all Internet. I typed some key words like Water scarcity in Australia. I look through all the web pages and gathered the beneficial information and type them into search box once again. For instance, I found one of the solutions of water scarcity in Australia is Cloud seeding and I typed this term into search box to get further information. I spent about 40 minutes on researching and found 2 websites for each solution. I haved verified all these sources were all written by reputable professors, scientists or publishers by researching these people and publisher to ensure if their dependency is strong enough for my paper. Some of my sources were another scientific paper. 3.0 Findings Two of the most severe fresh water issues in Australia were water scarcity and water pollution, these problems have existed for last of a decade. These two water issues could be a massive problem for Australia. Cloud seeding was a significant solution which throws drikold into cloud, it could increase supply moderately in Australia. Figure 1 demonstrated the mean of precipitation of seeded clouds was 2X103 m3 exceeded from unseeded clouds, it means seeded clounds can actually raise the percipitation (E. J. Smith). In fact, a great percents of water in Australia was polluted by plastics. Meanwhile, Australian plastic production had increased from 170 thousand in 1950s to 280 million in 2011. Figure 2 shows the distribution of plastic pollution in water of Australian city . Most heavy polluted cities were concentrated in the south-eastern and north-western Australia, the place where need to control the plastic production. Some cities in south-eastern Australia had over 15500 km-2 of pl astic concentrations. During the a long term of flowing, these plastics could be broken down into small fragments within 5 mm length, which commonly called microplastic and damaged to the food web and ecosystem easily. Therefore, we had two methods to solve this issue. Approximately 37% of plastics were used for manufacturing disposable packaging, comprising bottle, cups and bags,hence, the first solution was reducing the production of single-use plastic package and decreased the demand of using these plastic manutacture by advocating awareness of this water issue (Schneider J 2013). Another efficient solution was enact the laws which prohibit people and also factories from dumping plastics into sea.

Via this solution, Australia could have sufficient supply and overcame water scarcity lightly. But on the contrary, cloud seeding can be very costly. In most of the cases, it takes millions of RMB to implement one cloud seeding, therefore, Australia would better have a strong economic background beforehand like developing their agriculture or IT industry. On the other hand, as for the water pollution in Australia, most of water is polluted by fragmented plastic and majority of people and factories concentrated in the eastern coast of the Australia, so we could see eastern Australia is more polluted than any other part of Australia. Moreover, because it is hardly to eliminate all these plastic pollutants and made sure there is no plastic contamination in the furture in a scientific way, we could just do it in a political approach. For instanc e, government could enact laws of environmental protection or making some advertisments to persuade people do not throw plasctic bags or products into any kind of natural water source. In addition, some eco-friendly organizations can just simply set some dustbins around those highly polluted cities for recycling the plastic. But its a little bit tough for them to conquer water pollution via this method. All in all, I think Australia can conquer these two water issues based on the previous contents. 5.0 Conclusions and Recommendations In general, cloud seeding still got a substaintia chance to resolve water restriction by it extra precipitation. Australia just need to develop their economy and have enough capital to conduct these experiments. To handle the increasing plastic pollution in Australian water, government have appeal people do not throw any plastic manufactures casually and set several laws to forbid people from doing this, in particular the eastern part of Australia. The effectiveness of this measure rely on the governmental actions and Australian qualities. There are some limitations in this scientific paper, first of all is source restrictions. Sources in this paper are all from Internet. The research suggestion is using books references, because books always much more trustworthy than websites. If we get enough money, we will find a new scientific way to reduce the plastic pollution in Australian water.

Satire, humor and irony

In the Atwood’s short story, there are two speakers. One is trying to write a story while the other gives his opinion or views on the words that the former is using for his story. Their conversation centers on the mistakes or errors in the writer’s choice of words. The poems in the readings show that irony and satire need to be humorous at all times. Shakespeare’s poems did not contain humor. He only made use of irony in writing his pieces most particularly the poem, â€Å"My mistress’ eyes are nothing like the son. ’ On the other hand, Kennedy’s poem, â€Å"A Visit from St. Sigmund Freud,† is satirical but not entirely humorous for it talks about a very serious matter. In talking about Freud and Santa Claus, Kennedy did not utilize humor. His writing took on a serious tone just like Shakespeare did for his poem. The plays of Seinfeld and Leguizamo are very appropriate as readings for humor, irony, and satire for the writers of the said plays wrote them for the purpose of entertaining the readers. The goal of the said plays was to invoke laughter. They were meant to be humorous. They are clear examples of how humor is taken as the theme of literature.

Analysis of The film 12 Angry Men Jason Lovett MBA 611 Richard Devos School of Business Management Northwood University Executive Summary The Movie Twelve Angry Men is the ultimate example of a group of people forced to interact in order to reach a single, defined goal. The jury, which consists of 12 men, must deliberate until a unanimous decision is reached. In this specific example, which takes place in a New York courthouse, the decision holds the life of an 18 year old in the balance. The movie is presented in a manner that allows the viewer to be the invisible jury member and sit in as they deliberate the fate of the defendant. The first vote is 11 to 1, finding the defendant guilty. The 12 men ride a rollercoaster of†¦show more content†¦They are not receptive to any ideas opposing their own or the facts that they have accepted, meaning Juror number 8s position that he has doubt as the defendants guilt. Juror 8 has stated that he is simply not sure of the defendants guilt. He says and is able to convince the others that he simply wants to talk about it for an hour. 8 begins his explanation of why he thinks the way he does by telling of the defendants childhood, in which he frequented foster homes and was the known victim of abuse. All this, while his father was serving time in jail for forgery. Juror 8 is appealing to the others human compassion side in describing the childs rough childhood and upbringing. He pleads to the other jurors to simply give the boy a chance, for the first time in his life. This attempt at touching the others has gotten 3 to get out of his seat and move closer to 8 holding a picture. 3 continues talk of his son and his raising of him and how their relationship has been affected. The manner with which the man is speaking and his facial expressions make it painfully obvious that he has some great sadness when speaking of his son and even says that he has not heard from him in two years. Juror 10 is quick to point out that we do not owe him a thing.

How Economists Define the Revelation Principle

The revelation principle  of economics is that truth-telling, direct revelation mechanisms can generally be designed to achieve the Bayesian Nash equilibrium outcome of other mechanisms; this can be proven in a large category of mechanism design cases. Put into other words, the revelation principle holds that there is a payoff-equivalent revelation mechanism that possesses an equilibrium in which players truthfully report their types to any Bayesian game. Game Theory: Bayesian Games and Nash Equilibrium A Bayesian game has the most relevance in the study of economic game theory, which is essentially the study of strategic decision-making. A Bayesian game in one in which the information about the characteristics of the players, otherwise known as the players payoffs, is incomplete. This incompleteness of information means that in a Bayesian game, at least one of the players is uncertain of the type of another player or players. In a non-Bayesian game, a strategic model is considered an if every strategy in that profile is the best response or the strategy that produces the most favorable outcome, to every other strategy in the profile. Or in other words, a strategic model is considered a Nash equilibrium if there exists no other strategy that a player could employ that would produce a better payoff given all the strategies are chosen by the other players. A Bayesian Nash equilibrium, then, extends the principles of the Nash equilibrium to the context of a Bayesian game which has incomplete information. In a Bayesian game, Bayesian Nash equilibrium is found when each type of player employs a strategy that maximizes the expected payoff given the actions of all the types of other players and that players beliefs about the types of the other players. Lets see how the revelation principle plays into these concepts. Revelation Principle in Bayesian Modelling The revelation principle is relevant to a modeling (that is, theoretical) context when there exists: two players (usually firms)a third party (usually the government) managing a mechanism to achieve a desirable social outcomeincomplete information (in particular, the players have types that are hidden from the other player and from the government) Generally, a direct revelation mechanism (in which telling the truth is a Nash equilibrium outcome) can be proven to exist and be equivalent to any other mechanism available to the government. In this context, a direct revelation mechanism is one in which the strategies are just the types a player can reveal about himself. And is it the fact that this outcome can exist and be equivalent to other mechanisms that comprise  the revelation principle. The revelation principle is used most often to prove something about the whole class of mechanism equilibria, by selecting the simple direct revelation mechanism, proving a result about that, and applying the revelation principle to assert that the result is true for all mechanisms in that context.
