Anotated Bibliography No Child Left Behind Essay

What the paper â€Å"What’s Missing from No Child Left Behind? A Policy Analysis from a Social Work Perspective.† argues is that the No Child Left Behind bill might not be accomplishing its purpose. Moreover, the paper sheds light on the social and emotional risk factors that prevent students from succeeding in school. In the end, the article suggests that school social workers are capable of eliminating these barriers by applying in school interventions to address the psychosocial factors that highlight the difference in achievement at school. School social workers are also capable of advocating for an education policy change that looks beyond test scores and help at risk students succeed in school.

Results indicate that in between 2001 and 2005 statewide assessment of science and writing increased but it decreased in the social studies, arts, humanities, and computers. The research teams found that there are few themes that come up at almost every school. The first, which is an obvious one, is that for subjects that are not tested for under the No Child Left Behind bill, the schools reduced their resources and the effort that the school puts into these areas dropped. Second, is an interesting method because they take material away from tested subjects and integrating them into the classes that are not tested for. Just so the teachers that are going to be tested have more time to focus on the testing material. The last theme is that there is no change observed, everything seems to be the same as before the No Child Left Behind bill.

Black Fly Beverage Company Essay

Black Fly Beverage Company is a small beverage company based in London Ontario. The company has achieved recent success in the selling and promoting of their first alcoholic beverage, the cranberry/blueberry vodka cooler. The immediate success of this product presents two critical issues that the company must address. These critical issues are: †¢Black fly must expand its product mix in order to capture a larger market share in order to compete with larger established brands within the market place †¢Black Fly must also address capacity issues that will arise with an increase in demand or introduction of a new flavor Analysis. Current Situation Black Fly’s cranberry-blueberry vodka cooler has been well received by consumers due to its natural tasting ingredients and no chemical sweeteners producing a premium product different than existing similar beverages. The company now must take this opportunity to give their consumers another product to further explore the brand. Attempting to penetrate deeper within their current product will not allow its customers to further explore their favorite brand of vodka cooler. This will cause Black Fly to begin to lose their customers to other competing companies that offer multiple products and flavors (see exhibit 9). Black Fly also must also address the company’s capacity issues in order to allow them to meet the LCBO’s average order lead-time of seven days. At full capacity Black Fly is meeting the required lead time with minimal margin of error to account for delays, however, during the holiday season, which will occur as early as next month, the company will not be able to keep up with the increase in demand and will fail fulfill the LCBO’s order in time (see exhibit 7). Options The first option available to Black Fly would be to expand its product mix with the addition of a new flavor to compliment their existing cooler. The company will be able to take advantage of economies of scale through the current production; therefore a minimal cost of $30,000 will only be needed to cover development and merchandising fees. To cover this initial cost Black Fly will have to sell an additional 127 cases a month to break even, an increase of 10. 58% (see exhibit 2). It has been projected that adding another flavor to the product line could increase sales by 50 to 75 percent. This projected increase in sales would produce an annual expected ROI of 373% and 609% respectively (see exhibit 5). If however sales increased by only 10% due to the risk of cannibalization of their original recipe then the expected ROI would be -5% (see exhibit 5). This increase in sales however will put additional strain on the company’s current capacity (see exhibit 8). A second option to Black Fly would be the addition of a new specialty spirit-based product called â€Å"Spiked Ice†. This packaged ready to freeze cooler would be a non-competing product to the already successful cranberry-blueberry vodka. An advantage to this product is that there is no other product similar to it out in the marketplace. The LCBO has also committed to sell 8,000 cases of the product over the four summer months, which would produce revenues of $277,200 (see exhibit 3). Over this four month period this option will produce an ROI of 15% (see exhibit 6). To produce â€Å"Spiked Ice† the company however will have to purchase expensive machinery costing $500,000 and spend an additional $40,000 on merchandising and product development. To cover these costs Black Fly would have to sell an additional 7,585 cases of â€Å"Spiked Ice† (see exhibit 4). This may prove difficult as this new product is very seasonal producing higher sales in the summer months and potentially smaller sales in the fall and winter months, a time in which the LCBO has not committed to sell this product at this time. Another disadvantage to this option is the space that this new machinery would occupy in the already small warehouse. Black Fly’s current facilities cannot produce â€Å"Spiked Ice† and the original vodka simultaneously which would result in Black Fly loosing monthly revenues of $23,641 (see exhibit 1). Recommendation It is apparent that Black Fly must attempt to offer a variety of products to enhance its product mix and to keep current customers from trying other flavors offered by other competitors. At this time the best way to proceed with this will be to launch a new flavored vodka to compliment the already successful cranberry-blueberry vodka. The low initial costs and economies of scale gained through this option will allow Black Fly to introduce this new flavor quickly and efficiently to capitalize sales during the upcoming holiday season. To help address the concern of future capacity issues it would be recommended that Black Fly hire two more part-time workers and to run the production process seven days a week. This will be possible due to the expected high ROI associated with this option. This increase in production will allow the company to complete six full runs amounting to 3000 cases within the seven day lead time required by the LCBO ( see exhibit 10). In the future it will become necessary to upgrade to a larger facility and at that time it would be beneficial to begin producing â€Å"Spiked Ice†, however at this current time, given the company’s limited time in the market, it is suggested that Black Fly only pursue the launching of a new flavor. After the company has received sales from the holiday season the company will then be able to better address the possibility of relocating to a new warehouse and address their plans for â€Å"Spiked Ice† for the upcoming summer months.

Zaha Hadid

She said that, â€Å"It's not a matter of borrowing from here and there and blending it all together in a composite. Rather, there's a stream of events, each of which is an experiment. † So having said that, Gaza Had got influenced by many architects from the past, yes, but she never copied. She experiments. That is why she said that all her projects are a kind of experiment. She herself makes the experiment, and she herself tests the experiment in making a lot of possibilities and never stays at the same point.Gaza Hade's idea is that everyone can experiment but it is easier to experiment when you're younger because you have many questions and by that, you make experiments and you answer your own questions . Hade's concerns rose throughout the time because she said that day by day, people get less and less inventiveness. People get less curious about architecture, which makes her want to change it. [2] Gaza aims to build and her ideas that make images turn into construction. She always thought of the energies. Energies that causes the building to appear. The energies.Energies that causes the building to appear. Appear in a way that we couldn't imagine that it exists. With Gaza Hade's modernity, she wanted to change the world. Change for the better through architecture. Her aspects in changing the world through modernity are a lot. First, the technology, using the present resources that could harness a lot of possibilities but what Gaza Had wants is to make a form to its minimum. Minimum that meaner the future, the new and the modern. Second is changing the world by its act. Gaza Had wanted the people to open their eyes.The world is new but we Just don't recognize it. Modernity is the new world. Gaza Had doesn't invent what she designs. She makes new forms and new ways rooting or modernity. What I noticed about Gaza Had is that yes, she is fond of modernism. Modernism meaning edgy shapes and geometric forms, but she changed it. Looking by all her designs , there is a similarity. The curves that are present in all of her designs are much seen by the people. This shows her feminism. Not being biased to the sexuality, but it shows how different a woman can do with her own design.PEAHEN SCIENCE MUSEUM The Peahen Science Museum located in Wolfhound, Germany that was completed in November 2005. The concept and idea of this building is a magic box where people are capable of peeing their minds with curiosity and desire for discovery in all who open it. Just like the building, since it is a science museum, it should speak to its self. Science makes us curious and this building gives you the desire to enter and to discover. Science makes us curious and this building gives you the desire to enter and to discover. 1] The Peahen Science Museum as described by Gaza Had, â€Å"the most ambitious and complete statement of our quest for complex, dynamic, and fluid spaces. † It does not simply imply a normal building but it adds the technolog y of today. This building s designed to not to obey the standard rules of construction but Had made a realm of possibilities. She always thought that nothing is impossible because this building requires new methods and materials in order to build. As said by Gaza Had, â€Å"to create an urban field on the ground, with an object above was a rare opportunity for us. Looking at it from the outside, it looks so massive and complex which makes it look like a spaceship. It shows a huge hold on the ground. Same as entering from the inside, the massiveness is still there and transgress occurs. What I like about this building are the lights. It is easy to make lights in a very simple way, yes, but Gaza Had did it differently. Making the lights small which makes the concept bring back to life. The desire to discover is what they want to achieve like questioning why are the lights like that?Why aren't the walls are enclosed properly? Why does it have to be this massive? It makes us questions things and discover with our own minds. Having number of columns that makes it float makes the next level of the building columns. Which makes it unique and strange at the same tame. She was able to make open spaces that makes it look like not claustrophobic. Because imagine this building without the windows and the open spaces it feels like no one would go and enter inside that is a contrary to their concept of a magic box. Umber of columns that makes it float makes the next level of the building columns. Which makes it unique and strange at the same tame. She was able to make open spaces that makes it look like not claustrophobic. Because imagine this building without the windows and the open spaces it feels like no one would go and enter inside that is a contrary to their concept of a magic box. I think what Gaza Had did to this building was an experiment. Not that she had fun making in or something, but experiment of design.From what I said earlier, Gaza Had always wanted experi ments but it never stays the same. Had make buildings massive yet breathtaking. What Gaza Had designs are simply answers to our questions. She designs by her passion and energy that correlates from her intentions and ideas. Gaza never make things complicated she's Just making architecture a realm of possibility for everyone to appreciate it. Http://www. Gaza-had.

Involvement in Iraq Essay Example | Topics and Well Written Essays - 500 words

Involvement in Iraq - Essay Example After US invasion of Iraq and Afghanistan on the premise that the two latter nations were involved in the generation and manufacture of biological weaponry, the US was able to quell international concerns of terrorism brought by the two Middle East countries (Tucker, 2010). However, even after quelling Iraq and Afghanistan’s terrorism threats, the US is still very much mixed up in Iraq and Afghanistan. This paper will question whether or not the US involvement in the two nations is necessary. It is irrefutable that the US invasion of Iraq and Afghanistan has ensured global peace and security. For almost a decade now, American foreign policy has been pegged on the wars in Afghanistan and Iraq. At the beginning of 2011, there were 50,000 US soldiers in Iraq and 100,000 in Afghanistan. The involvement of the US in both countries is still robust despite the decline of American soldiers compared to previous years (Rashid, 2008). This involvement is entirely uncalled for, and is rather improper. The US should no longer be involved in the affairs of Iraq and Afghanistan, especially because of the cost implication associated with such involvement. In American history, Iraq has been the second most expensive choice of war, after Vietnam in the 1960s (Tucker, 2010). In order to deter the further use of military and economic resources in the two nations, it is pertinent that the US seizes its involvement in the countries. While US troops were expected to leave Iraq by December 2011, several thousand soldiers remained. The main role of the troops has been to advise and train Iraqi police and military forces, as well as conducting antiterrorism missions. After the loss of 4,300 American lives and more than one trillion dollars, it is evidently time for America to cut its losses and accept the positive effects of the war and simply withdraw from Iraq and Afghanistan (Woodward, 2010). War is a costly affair with regard to

The Uses Of Liberal Education Essay Example | Topics and Well Written Essays - 750 words - 3

The Uses Of Liberal Education - Essay Example Using logos, the author explains that poor people lack the power to negotiate their position and life condition. They are trapped by external and internal forces, which sometimes appear too overwhelming and thus insurmountable. The only weapon they can use to navigate through life is an equal force to match the forces they are encountering. This force for them is violence and gun culture. It is for this reason that many of them end up in prison. If they knew that there were other ways to negotiate and that they too could enjoy a voice in public matters, these people could come out of the vicious circle of poverty. Pathos has been effectively employed- mostly to highlight the plight of those who suffer from extremes of poverty. It is most prominent in the case of Niecie, the inmate at Bedford Hills who first gave the idea of the use of liberal education as a weapon for success. Viniece Walker was a twenty-year-old when she came to the prison and during her time there, her HIV had progressed significantly but she had defiantly pursued a college degree in psychology. She had been described as the best inmate because apart from her education, she was also fully engaged in offering counseling services to inmates. Ethos comes into action when the author tries to establish the moral grounds for his research. Why should the poor always remain poor? Why must the rich have the tools of negotiation while poor were completely ignorant of them? The author raises the question: why are poor people poor? And realizes that none of the people he interviewed mentioned lack of money or proper jobs. Some of them had a vague idea; others clearly felt that lack of education was the reason. The ethics of this argument lies in the inability of the poor to access the tools of negotiation that rich possessed.

Strategic Management in a Global Environment - Assignment Example Other issues that may also arise include the lack of infrastructure which may result to challenges during distribution of the products and supply management. In order to conquer entry barriers, the market has to choose to go it alone, form partnership or employ local players. c) Strategies to build profitable position. After finding entry strategies, the next thing leaders should focus on is ways on creating defensible position that will meet the businesses long term goals (World Bank & International Finance Corporation, 2013). This can be achieved through understanding of their competitors, marking the target customers and finally through configuration of their local operations in order to deliver your capabilities efficiently. BRICS is an acronym that stands for an association of some five emerging global economies. The members of this association hail from developing countries or the newly industrialised countries. The distinguishing factor is that these countries have fast growing economies and they hold great influence on both global and regional affairs (Pant, 2013). Despite the praise the BRICS get from their commentators, they have received criticism as well. For instance, they are said to be defenders as well as promoters of developing states. BRICS is likely to face some issues in the coming decade due to a number of factors. For example, the West is yet to accept that the group is running by itself. With the creation of BRICS development bank, western analysts cited that BRICS states were very different and therefore could never agree. The other issue within the BRICS is the quantity of the stated issues in the Fortaleza Declaration as well as the Action Plan (Stuenkel, 2014). This is because some parts of the document were largely criticised. One scholar Alan Alexandroff wrote that the group was â€Å"almost breathtaking chutzpah† in condemnation of the groups’ unilateral action. He argued that â€Å"no state should

Transition of Art to Photography in Terms of Realism Essay

Transition of Art to Photography in Terms of Realism - Essay Example Presently, such a world seems unimaginable thanks to photography: it comes with visual souvenirs; pictures of common and prominent people; advertising pictures that create a desire within the public while, at the same time educating them concerning all products the modern consumer culture is capable of offering; medical, diagnostic devices; incredible perceptions of exotic places, together with the outer space; world news pictures; and most significant, pictures of the events, as well as intimate moments of personal life (Keil 19). The photography technology is partly chemical and partly optical, dating back in 1839. Shortly after its instantaneous discovery by William Henry Fox Talbot of England, together with Louis Jacques Mande Daguerre of France, photography get used in documenting foreign places of interest like India, the American West and the Holy Land. Apart from that, it got applied in portraits along with photographs of kings, statesman, as well as theater or even literary personalities. However, during the 19th century, cameras were in most cases in the hands of either professionals or entrepreneurs who were self-educated thereby trying photography as a trade. Photography does not require professional licensing or even guild membership; therefore, in the mainstream, anyone has the capability of buying the equipment, obtaining the directions, and proceeding. This directness of the medium makes photographic practice liberated from the traditions, which had grown up throughout painting or a variety of printmaking arts (Keil 32). With the introduction of precoated dry plates in 1878, the tiresome and cluttered coating of glass plates inside the darkroom or even dark tent, for those photographers out in the field got eliminated, and with the availability of precoated photographic papers, printing of photographs turned out to be much easier, while, at the same time, more predictable. As a result, photography could be exercised by hobbyists or amateurs, mor e so by lovers of the medium since the majority of the people, who had the leisure for an advanced hobby such as this one, were not only educated, but also sophisticated, and desired to come up with photographs resembling Art (Keil 47). In the past, film cameras filters got used in the modification of both the spectral content i.e. color, intensity of light, while, at the same time, generating outcomes like soft focus. However, digital cameras tend to operate differently when it comes to color; there is a possibility of performing color modification in camera with ease by setting white balance. Therefore, for film warming, as well as cooling filters, or those filters capable of converting fluorescent light unto daylight where necessary, digital has the ability of achieving the same effects through internal operation of the digital data. There as a number of filters needed for digital including a polarizing filter, special effect filter, a UV filter, filters for infrared effects, a n eutral density filter plus a given graduated neutral density filter. It is impossible to digitally simulate the results of a

Reaction Paper (Political Psychology)- Perceptions & Attributions Essay

Reaction Paper (Political Psychology)- Perceptions & Attributions - Essay Example ons are not contrived in vacuum, but have a lot to do with the past held beliefs and prejudices, recent alterations motivated by the framing of political issues and the persuasion techniques used by the vested interests. Granberg aptly defines political perception as the â€Å"process by which people develop impressions of the characteristics and positions of political candidates, parties, and institutions (p.70).† I personally feel that political perceptions do play a vital role in determining outcomes and consequences in a democratic society. The perceptions of the masses towards political candidates and parties do often have a key role in the determination of the vital factors like the levels of satisfaction with the political institutions; trust in the state and the ensuing responses and actions by the citizens (Gadot, 2006). It seems that both the external features and the perceiver’s internal orientation tend to affect the ultimate nature and potency of such perceptions (Granberg, p.70). Moreover, an astute political candidate is often aware of the power that perceptions command in the overall process of the determination of the final political outcomes in a society. That is why it has been seen that political candidates do often tailor their messages to suit the audience they intend to address. For example, Lyndon Johnson often resorted to delivering fiery speeches, when faced with a highly stimulated audience (Granberg, p.71). Pragmatically speaking, political perception is an unpredictable entity determined and influenced by an array of factors that happen to be both subjective and rational at the same time. Still a thorough observance of the political campaigns facilitated by the developments in the digital media has established that persuasion by the political candidates does often have a crucial role in influencing the political perceptions. The paper by Iyengar establishes convincingly that the vantage point from which people perceive a particular

Savior Siblings Essay Example | Topics and Well Written Essays - 1750 words

Savior Siblings - Essay Example This may involve: pursuing parenthood through adoption and foregoing conceiving children who have blood ties, applying a collaborative reproductive procedure e.g. surrogacy or donation of an egg, embryo or sperm with a parent who is free of the genetic illness being the child's genetic parent, following conception women may undertake pre natal diagnosis i.e. PND though the procedure involved has an inherent risk and also raises a challenge in the decision as to whether to terminate the a pregnancy of a fetus which is affected. PND is recognized and a number of women have continually ended pregnancies in their effort to conceive a child with no genetic illness under debate. PGD/embryo screening has the merit that it informs a woman whether her baby is affected or not with the genetic problem In question or under test during her initial stages of her pregnancy; this enables the said woman to make an informed decision as to whether to terminate or continue with the pregnancy. As such, owing to the ethical, psychological and physical reasons, PGD option is more preferred to PND/fetal screening. The initial PGD application was reported in 1989 and so far it is applied as detect quite a big number of a genetic conditions e.g. determining embryo's sex ( this have medical relevance for sex-related conditions such as hemophilia and Duchene's muscular dystrophy), identification of the single gene conditions such as spinal muscular atrophy, thalassaemia and cystic fibrosis. Human Leucocytes Antigen tissue typing together with PGD may make it certain the fact that an embryo is not affected by a severe genetic condition/s and also guarantee that the said child possibly will be a tissue-matched donor for an existing affected sibling requiring stem cell transplant. The embryo is not prone to extra risk as the equivalent biopsy carried out for PGD may be applied to check for tissue typing. Donating cord blood stem cell is not invasive, thus postnatal intervention concerning the "savior sibling" is not possible, and hence, no physical harm risk is incurred. I agree with the authority's decision of rejecting the request by the Whitaker family on the basis that it was not right to create a human life with the express intent of saving another life. There are various ethical arguments in opposition to the notion of 'saviour siblings' i.e. wrongful instrumentalization of the child, welfare of the child and slippery slope. Wrongful Instrumentalization of the Child Wrongful instrumentalization of the child is founded on the grounds that any child should be sought for his/her own sake. The concept of wrongful instrumentalization holds both the notion of choosing the character of a child and conceiving him or her so as to provide the ends of another child. The 'savior siblings' idea renders its application as a tool even though for superior ends. In case of conceivement of a savior sibling, he/she should be taken care of as a human being with his/her personal rights. It can not be accepted where the single reason for conceiving a child as a "savior sibling" is to make available a supply of stem cells that will be utilized to take care of a child on hand ( Immanuel kant pp) Welfare of the Child Welfare of the child

Hitler Fascism and Mussolini Fascism Essay Example | Topics and Well Written Essays - 2000 words

Hitler Fascism and Mussolini Fascism - Essay Example This research will begin with the definition of fascism as a form of totalitarian government, with an authoritative dictator who takes control of the entire nation, its people and economy. It is a political ideology with a radical nationalism concept, which initiates a ‘revolution’ for promoting the fascist principles. Basically rejecting the idea of socialism, capitalism, and democracy, Fascism is anti-liberal in nature and has a sound emphasis on ethnocentrism and militarism. Benito Mussolini in Italy and Adolf Hitler in Germany are the two notable dictators, who embodied fascism in their countries and claimed ultimate power over it. The form of fascism adopted in Germany and Italy by these leaders greatly differed in various cultural, social, economic and political ideologies. The Italian fascism was shaped by Mussolini for his pursuit of nationalism while the German fascism was distorted to the social and political beliefs of Hitler. As defined by Roger Griffin, â₠¬Å"Fascism is a political ideology whose mythic core in its various permutations is a palingenetic form of populist ultra-nationalism.† It is a form of counter-revolutionary politics that arose during the World War period. The socio-political changes including the rise of socialism and communism in the aftermaths of the World War gave way for a new political setting in the name of ‘Fascism’ in Italy and other European countries. The rapid social upheavals as well as the devastation of societies and economy were the instrumentals to the rise of Fascism and Nazism in these countries. The Fascist ideology established by Hitler was based on his own personal reflections, Mein Kampf, which means My Struggle, written during his days before hailing power. On the other hand, Mussolini shaped his ideology after he took control over the Italian State. Mussolini’s Fascism stresses on dictatorship with extreme rights, typically excising power over the people and the nation, embracing an overarching state ideology. (Griffin, 1993).Similarly, Hitler’s Fascism favors aggressive nationalism, totalitarianism, fanaticism, and seeks blind obedience of its followers towards their authorities. Despite their different stands on espousing the ideologies of Fascism, they established it in a successful manner. â€Å"Hitler and Mussolini were both dictators, both lead totalitarian regimes in their countries and cooperated together during World War Two.† (Husic, n. d.). In 1919, when Italy was devastated in the aftermaths of the World War, it prospected for a new political aspect, which Mussolini took it as an advantage to gain control over the country. Taking this perfect opportunity, he introduced Fascism into Italy and established his rule under the autonomy of the king. However, with his followers, he organized paramilitary forces which terrorized the country with violent attacks and ultimately, took over the sovereign government under his power. (Payne, 1983). Similarly, Hitler’s Nazism was the ideologies and policies of Fascism which stressed on the superiority of the Aryan people. Hitler called for the unification of the German-speaking people into a one single empire. He was determined in creating a racially pure state which led to atrocities like Holocaust. He organized various military forces to maintain his power all over the country as a fascist dictator. Unlike Fascism, Hitler’s ideology held racism as its prior importance while the state was at a secondary in preference. Similarities Both Mussolini and Hitler had common socio-political viewpoints for dominating the world with their barbarism and fanaticism, which together created

Lefebvre's Ideas about Social Space Imply a Re-Evaluation of the Role Essay

Lefebvre's Ideas about Social Space Imply a Re-Evaluation of the Role of Graffiti in the Politics of City and Urban Life - Essay Example There exists a long history of various cultures leaving symbols and writings of their experiences from the age of the Pharaoh’s Pyramids to Hadrian’s Wall, the Byzantium Empire, and the middle ages. However, it is only half a century ago when graffiti started being linked to the culture of the urban youth as well as the political beliefs of the social movements of the 1960s. Graffiti writers from New York and Philadelphia began to create new and innovative styles with new materials and writing styles. They also made use of increasing spaces in the urban areas. Graffiti soon grew to be a global phenomenon. It is now a common sight in numerous urban areas all over the world. It adorns or disfigures public areas, depending on the viewpoint of the person analysing the works. Graffiti has sometimes been viewed as a disfigurement of the city walls. However, many people simply consider it is a modern way used by the youth to express their viewpoints. Henri Lefebvre separated s pace into three groups: representations of space, spatial practice, and representational space. According to his ideas, every piece of art that is included in the public space will slowly integrate itself into that space, and frequently ends up being a part of that very public space in such a way that it cannot be separated from that place. The import of public art lies in the fact that the more it is integrated, the more effectual the public space will be made, and then both its functional and representative aspects are confirmed. Its importance is also found in its political as well as activist functions, since public art usually denotes the significance of public space. Any work of art that is in the public space tends to acquire its significance when it is recognised as a part of the public. The art works that created in and for the public space, for instance graffiti, are the types of artwork that take into account the framework of urban. They are deemed to be a part of the civ ic realm as they are meant for the public spaces as well as the citizens of the location in which they were created. In that sense, they cannot be differentiated from their public spaces, where by integrating themselves in the public space, they create the identity of that area. It is a common thing for citizens who live near areas that are filled with graffiti start to identify the area by the different drawings on the public walls. The aspect of the ‘lived’ dealt with the third branch of Lefebvre’s triad in comprehending the social space, where he associates it with the representational space. The representational space speaks to the more unstructured and intimate interactions of citizens in its surroundings. Whereas human interventions such as graffiti are delineate the connection that the citizens have with their capital, the theory of Lefebvre’s triad goes further in illuminating that the notion of ‘lived’ has an inclination of going to t he scheme of non-verbal symbols. In that sense, Lefebvre affirmed that this concept stimulates the imaginations that citizens who view them have about themselves (Zukin, 1995). Lefebvre’s theory explored new methods of comprehending of the prevailing procedures of urbanisation, as well as the conditions and outcomes on any scale of the public reality; whether from the operations of daily life, through the municipal scale, to the international flows of capital, people, ideas, and information (Lefebvre, 1996). Concurrently, this premise has the potential to connect urban design and research operations because of its programmatic investigation of the connection between the critique of urbanism, the urban study, and the visualisation of a new kind of

Stylolites - Greek Essay Example for Free

Stylolites Greek Essay Stylolites are irregular discontinuity or non structural fractures which are found in limestone plus other sedimentary rocks. Stylolites come from compaction and pressure solution during the process of diagenesis and it might be blown up by subsequent groundwater flow. Stylolites most of the time comes into view as uneven discontinuities in the outcrops along with hand samples and they are frequently lined up with clays which are quite impossible to solve, opaque and dim organic matter. The phrase stylolite originated right from the Greek for pillar, ‘stylo’ (Paul 19). A stylolite is not a structural fracture even though they have been described as a structure of anti crack whereby both sides are moving together instead of moving apart. Proof exists in the structure of fossiliferous limestones in which the fossils crosscut by a stylolite and it is said that only one of the half still exists. The other half has already been dissolved away. Stylolites in one way or the other might be an important geologic feature which affects the reservoir quality and most probably the reservoir management in a good number of carbonate reservoirs. Emaciated, discontinuous paved zones which are connected with stylolites take place in the massive, soaring porosity dolomites of the Upper Smackover at Jay/LEC Field and they are actually the source of horizontal baffles to perpendicular flow suspected ever since the early days of production in combination with the corroboration by full field reservoir performance studies. It is important for the thin, perpendicular flow baffles to match historical water flood arrivals in both full field plus a little area simulation modeling that led to the wide spreading re-examination of the core and recognition of these formerly undetected cemented zones connected with stylolites. Field wide conventional coring provides an outstanding foundation database for describing the physical nature, circulation of stylolites and the most related cements. In the ontong Java Plateau chalk sediments mechanical compaction actually causes a porosity decline from let us say 70% to 50% in the topmost 600 m. mudstones together with wackestones they tend to have comparable porosity for the reason that the wall cavity of the microfossils add up in the same way to pore-space and to the solid phase. The original pore filling cementation might be interconnected to the occurrence of the primary stylolites at approximately 830 m together with a decrease in massive sediment. Temperature is in the region of 20%C and valuable burial stress 6 MPa (Paris 79). Stylolites might derive in primary diffuse green bands which are enriched in smectite chlorite, most probably those of volcanic origin. The bands are replaced approximately below 490 m by supplementary distinct flaser structures that are enriched in smectite. The commencement of pressure dissolution consequently corresponds to an interval of diminishing mechanical compaction. Below 790 m the chalk consists of biogenic opal-A, nevertheless the opal-CT increasingly it takes over 790 m and most probably below 1130 m quartz becomes the only silica phase. This process coincides with the cementation frontage, beneath which depth pore-filling calcite cementation makes porosity to go down. Silica-Ca complexes in the pore water might not become stable when the high temperature and age cause quartz to turn out to be the most established silica phase. The pore filing cementation tends to load microfossils completely with the intention that textual differences are at the present clearly visible on the porosity log. The stylolite bears a chalk of the Gorm field, the Central North Sea, porosity is 20%-40%, lower than OJP chalk however it is higher than OJP limestone. The variation is reflecting cementation of microfossils while the matrix porosity is comparable to the OJP chalk. The variation between OJP and it is not possible to explain Gorm field chalk alone by the early introduction of hydrocarbons, which does not exactly give an explanation of the cementation of microfossils. Nevertheless, another cause might be the excessive pressure in the chalk of the Central North Sea whereby the percentage amongst the temperature and effective burial stress far above the ground. Silica most probably has the equilibrated to quartz before stylolites exhibited so that calcite cementation was not held back at all by the silica diagenesis (Bradbury 197). Stylolites were observed during the Hampovica-6 well and they have been shaped in a stress field which tends to act homogeneously in excess of a long period of time without reactivating older, pre-existing fracture systems. Alongside the strike, they tend to cut off all the planes of different discontinuities, bedding together with fractures from the axial plane. Through the aforementioned statement, it shows that the stylolites were created after the final tectonic configuration of the structure which was presently in the well. That is to say, the two sets of dissimilar deformations point towards the two events of the similar compression that is confined to a small area in the part of limestone of the aforementioned well only. The reality is that in the other rock samples which are examined from this well they originate from more shallow and deeper parts than this interval, neither the stylolitization nor the significant structural deformations have been clearly observed. Slight thoughtfulness is given to the interior structure of the stone. They have written very few about the influence of stylolites, a most important parameter, as a way which is used to choose an appropriate stone, to forecast its outcome on applications plus their performance thereafter, not to talk about using stylolites as a analytic tool already during prospecting for stone deposits. This disrespect resulted in defaults more especially within limestone slabs and strips with pre-existing discontinuities into the stone just similar to stylolites. Very similar it applies to installation defaults for instance the proper attachment and prevention of slabs breaking for the duration of processing, installation, or even after placing. In point of fact, litigations and complaints within the stone sector concern floor coverings which contains problematic stylolites associated with cutting with-the bed, tripping, slipping and tentative accidents. In some sense the industry can be held responsible for this state of affairs, from the lack of geotechnical awareness to stylolites during mining and prospection at the quarries. Attention taken to possible defaults gives the quarry owner or stone supplier knowledge with a good understanding of the deposit and eventually it ensures satisfaction to customers (Bradbury 213). As a matter of fact, stylolites are mainly found in so many rock types together with sandstones, to slighter extent igneous rocks plus other deposits metamorphosed to a variety of degrees. On the other hand, limestones and dolomites are used in building and construction which forms the major group affected by the presence of stylolites more especially the stones that are having higher pure calcareous content. The stylolitic limestones are important in ornamental and decorative uses, marketed as marble. At present the nation is using stylolitic limestone for business purposes. They are used for making ornaments. The behaviors of stone materials are traced to conditions throughout the origin of the rock and to the tectonic appearance of the rock mass. The quarry investigations and laboratory capacity have then to be associated with the limestone applications in building frontages or pavements. Even though the general mechanical properties might be accepted, the very natural properties which are foot printed during genesis or those that are caused by the historical tectonic discontinuities might at times let people down during or after the stone application. The earliest examination of the stone material for possible disorders actually prevents default. It needs the understanding of the stylolites, a structural examination of the quarry beds to search for discontinuities, to prevent excessive tectonic stylolites to smoothen the progress of commercial block extraction. It applies to figuring out cutting direction to decrease the stratigraphic stylolites rate (Dean 117). Conclusion Inconclusive negotiations about the origin and the formation of stylolites have always been and they are still going on for more than a century at present. It does not sound academic but an extensive literature is readily available on stylolites whereby petite attempt has been made in which data is applied to the dimension stone industry. Apart from the significance of stylolites for descriptive purposes, the compulsory petrograhic examination standards, vertical and stylolites might be used to show the quality of the stone, when the subject to dynamic loading is on floors or pavements. Finally, at present people notice the presence of stylolites in areas subjected to tectonic actions and observed facts must be accepted as fundamentally right. Works Cited Bradbury, H.

K Means Clustering With Decision Tree Computer Science Essay

K Means Clustering With Decision Tree Computer Science Essay The K-means clustering data mining algorithm is commonly used to find the clusters due to its simplicity of implementation and fast execution. After applying the K-means clustering algorithm on a dataset, it is difficult for one to interpret and to extract required results from these clusters, until another data mining algorithm is not used. The Decision tree (ID3) is used for the interpretation of the clusters of the K-means algorithm because the ID3 is faster to use, easier to generate understandable rules and simpler to explain. In this research paper we integrate the K-means clustering algorithm with the Decision tree (ID3) algorithm into a one algorithm using intelligent agent, called Learning Intelligent Agent (LIAgent). This LIAgent capable of to do the classification and interpretation of the given dataset. For the visualization of the clusters 2D scattered graphs are drawn. Keywords: Classification, LIAgent, Interpretation, Visualization 1. Introduction The data mining algorithms are applied to discover hidden, new patterns and relations from the complex datasets. The uses of intelligent mobile agents in the data mining algorithms further boost their study. The term intelligent mobile agent is a combination of two different disciplines, the agent is created from Artificial Intelligence and code mobility is defined from the distributed systems. An agent is an object which has independent thread of control and can be initiated. The first step is the agent initialization. The agent will then start to operate and may stop and start again depending upon the environment and the tasks that it tried to accomplish. After the agent finished all the tasks that are required, it will end at its complete state. Table 1 elaborates the different states of an agent [1][2][3][4]. Table 1. States of an agent Name of Step Description Initialize Performs one-time setup activity. Start Start its job or task. Stop Stops its jobs or tasks after saving intermediate results. Complete Performs completion or termination activity. There is link between Artificial Intelligence (AI) and the Intelligent Agents (IA). The data mining is known as Machine Learning in Artificial Intelligence. Machine Learning deals with the development of techniques which allows the computer to learn. It is a method of creating computer programs by the analysis of the datasets. The agents must be able to learn to do classification, clustering and prediction using learning algorithms [5][6][7][8]. The remainder of this paper is organized as followos: Section 2 reviews the relevant data mining algoritms, namely the K-means clustering and the Decision tree (ID3). Section 3 is about the methodology; a hybrid integration of the data mining algorithms. In section 4 we discuss the results and dicussion. Finally section 5 presents the conclusion. 2. Overview of Data Mining Algorithms The K-means clustering data mining algorithm is used for the classification of a dataset by producing the clusters of that dataset. The K-means clustering algorithm is a kind of unsupervised learning of machine learning. The decision tree (ID3) data mining algorithm is used to interpret these clusters by producing the decision rules in if-then-else form. The decision tree (ID3) algorithm is a type of supervised learning of machine learning. Both of these algorithms are combined in one algorithm through intelligent agents, called Learning Intelligent Agent (LIAgent). In this section we will discuss both of these algorithms. 2.1. K-means clustering Algorithm The following steps explain the K-means clustering algorithm: Step 1: Enter the number of clusters and number of iterations, which are the required and basic inputs of the K-means clustering algorithm. Step 2: Compute the initial centroids by using the Range Method shown in equations 1 and 2. (1) (2) The initial centroid is C(ci, cj).Where: max X, max Y, min X and min Y represent maximum and minimum values of X and Y attributes respectively. k represents the number of clusters and i, j and n vary from 1 to k where k is an integer. In this way, we can calculate the initial centroids; this will be the starting point of the algorithm. The value (maxX minX) will provide the range of X attribute, similarly the value (maxY minY) will give the range of Y attribute. The value of n varies from 1 to k. The number of iterations should be small otherwise the time and space complexity will be very high and the value of initial centroids will also become very high and may be out of the range in the given dataset. This is a major drawback of the K-means clustering algorithm. Step 3: Calculate the distance using Euclideans distance formula in equation 3. On the basis of the distances, generate the partition by assigning each sample to the closest cluster. Euclidean Distance Formula: (3) Where d(xi, xj) is the distance between xi and xj. xi and xj are the attributes of a given object, where i and j vary from 1 to N where N is total number of attributes of a given object. i,j and N are integers. Step 4: Compute new cluster centers as centroids of the clusters, again compute the distances and generate the partition. Repeat this until the cluster memberships stabilizes [9][10]. The strengths and weaknesses of the K-means clustering algorithm are discussed in table 2. Table 2. Strengths and Weakness of the K-means clustering Algorithm Strengths Weaknesses Time complexity is O(nkl). Linear time complexity in the size of the dataset. It is easy to implement, it has the drawback of depending on the initial centre provided. Space complexity is O(k + n). If a distance measure does not exist, especially in multidimensional spaces, first define the distance, which is not always easy. It is an order-independent algorithm. It generates same partition of data irrespective of order of samples. The Results obtained from this clustering algorithm can be interpreted in different ways. Not applicable All clustering techniques do not address all the requirements adequately and concurrently. The following are areas but not limited to where the K-means clustering algorithm can be applied: Marketing: Finding groups of customers with similar behavior given large database of customer containing their profiles and past records. Biology: Classification of plants and animals given their features. Libraries: Book ordering. Insurance: Identifying groups of motor insurance policy holders with a high average claim cost; identifying frauds. City-planning: Identifying groups of houses according to their house type, value and geographically location. Earthquake studies: Clustering observed earthquake epicenters to identify dangerous zones. WWW: Document classification; clustering web log data to discover groups of similar access patterns. Medical Sciences: Classification of medicines; patient records according to their doses etc. [11][12]. 2.2. Decision Tree (ID3) Algorithm The decision tree (ID3) produces the decision rules as an output. The decision rules obtained from ID3 are in the form of if-then-else, which can be use for the decision support systems, classification and prediction. The decision rules are helpful to form an accurate, balanced picture of the risks and rewards that can result from a particular choice. The function of the decision tree (ID3) is shown in the figure 1. Figure 1. The Function of Decision Tree (ID3) algorithm The cluster is the input data for the decision tree (ID3) algorithm, which produces the decision rules for the cluster. The following steps explain the Decision Tree (ID3) algorithm: Step 1: Let S is a training set. If all instances in S are positive, then create YES node and halt. If all instances in S are negative, create a NO node and halt. Otherwise select a feature F with values v1,,vn and create a decision node. Step 2: Partition the training instances in S into subsets S1, S2, , Sn according to the values of V. Step 3: Apply the algorithm recursively to each of the sets Si [13][14]. Table 3 shows the strengths and weaknesses of ID3 algorithm. Table 3. Strengths and Weaknesses of Decision Tree (ID3) Algorithm Strengths Weaknesses It generates understandable rules. It is less appropriate for a continuous attribute. It performs classification without requiring much computation. It does not perform better in problems with many class and small number of training examples. It is suitable to handle both continuous and categorical variables. The growing of a decision tree is expensive in terms of computation because it sorts each node before finding the best split. It provides an indication for prediction or classification. It is suitable for a single field and does not treat well on non-rectangular regions. 3. Methodology We combine two different data mining algorithms namely the K-means clustering and Decision tree (ID3) into a one algorithm using intelligent agent called Learning Intelligent Agent (LIAgent). The Learning Intelligent Agent (LIAgent) is capable of clustering and interpretation of the given dataset. The clusters can also be visualized by using 2D scattered graphs. The architecture of this agent system is shown in figure 2. Figure 2. The Architecture of LIAgent System The LIAgent is a combination of two data mining algorithms, the one is the K-means clustering algorithm and the second is the Decision tree (ID3) algorithm. The K-means clustering algorithm produces the clusters of the given dataset which is the classification of that dataset and the Decision tree (ID3) will produce the decision rules for each cluster which are useful for the interpretation of these clusters. The user can access both the clusters and the decision rules from the LIAgent. This LIAgent is used for the classification and the interpretation of the given dataset. The clusters of the LIAgent are further used for visualization using 2D scattered graphs. Decision tree (ID3) is faster to use, easier to generate understandable rules and simpler to explain since any decision that is made can be understood by viewing path of decision. They also help to form an accurate, balanced picture of the risks and rewards that can result from a particular choice. The decision rules are obta ined in the form of if-then-else, which can be used for the decision support systems, classification and prediction. A medical dataset Diabetes is used in this research paper. This is a dataset/testbed of 790 records. The data of Diabetes dataset is pre-processed, called the data standardization. The interval scaled data is properly cleansed. The attributes of the dataset/testbed Diabetes are: Number of times pregnant (NTP)(min. age = 21, max. age = 81) Plasma glucose concentration a 2 hours in an oral glucose tolerance test (PGC) Diastolic blood pressure (mm Hg) (DBP) Triceps skin fold thickness (mm) (TSFT) 2-Hour serum insulin (m U/ml) (2HSHI) Body mass index (weight in kg/(height in m)^2) (BMI) Diabetes pedigree function (DPF) Age Class (whether diabetes is cat 1 or cat 2) [15]. We create the four vertical partitions of the dataset Diabetes, by selecting the proper number of attributes. This is illustrated in tables 4 to 7. Table 4. 1st Vertically partition of Diabetes Dataset NTP DPF Class 4 0.627 -ive 2 0.351 +ive 2 2.288 -ive Table 5. 2nd Vertically partition of Diabetes Dataset DBP AGE Class 72 50 -ive 66 31 +ive 64 33 -ive Table 6. 3rd Vertically partition of Diabetes Dataset TSFT BMI Class 35 33.6 -ive 29 28.1 +ive 0 43.1 -ive Table 7. 4th Vertically partition of Diabetes Dataset PGC 2HIS Class 148 0 -ive 85 94 +ive 185 168 -ive Each partitioned table is a dataset of 790 records; only 3 records are exemplary shown in each table. For the LIAgent, the number of clusters k is 4 and the number of iterations n in each case is 50 i.e. value of k =4 and value of n=50. The decision rules of each clusters is obtained. For the visualization of the results of these clusters, 2D scattered graphs are also drawn. 4. Results and Discussion The results of the LIAgent are discussed in this section. The LIAgent produces the two outputs, namely, the clusters and the decision rules for the given dataset. The total sixteen clusters are obtained for all four partitions, four clusters per partition. Not all the clusters are good for the classification, only the required and useful clusters are discussed for further information. The sixteen decision rules are also generated by LIAgent. We are presenting three decision rules of three different clusters. The number of decision rules varies from cluster to cluster; it depends upon the number of records in the cluster. The Decision Rules of the 4th partition of the dataset Diabetes: Rule: 1 if PGC = 165 then Class = Cat2 else Rule: 2 if PGC = 153 then Class = Cat2 else Rule: 3 if PGC = 157 then Class = Cat2 else Rule: 4 if PGC = 139 then Class = Cat2 else Rule: 5 if HIS = 545 then Class = Cat2 else Rule: 6 if HIS = 744 then Class = Cat2 else Class = Cat1 Only six decision rules are for the 4th partition of the dataset. It is easy for any one to take the decision and interpret the results of this cluster. The Decision Rules of the 1st partition of the dataset Diabetes: Rule: 1 if DPF = 1.32 then Class = Cat1 else Rule: 2 if DPF = 2.29 then Class = Cat1 else Rule: 3 if NTP = 2 then Class = Cat2 else Rule: 4 if DPF = 2.42 then Class = Cat1 else Rule: 5 if DPF = 2.14 then Class = Cat1 else Rule: 6 if DPF = 1.39 then Class = Cat1 else Rule: 7 if DPF = 1.29 then Class = Cat1 else Rule: 8 if DPF = 1.26 then Class = Cat1 else Class = Cat2 The eight decision rules are for the 1st partition of the dataset. The interpretation of the cluster is easy through the decision rules and it also helps to take the decision. The Decision Rules of the 3rd partition of the dataset Diabetes: Rule: 1 if BMI = 29.9 then Class = Cat1 else Rule: 2 if BMI = 32.9 then Class = Cat1 else Rule: 3 if TSFK = 23 then Rule: 4 if BMI = 25.5 then Class = Cat1 else Rule: 5 if BMI = 30.1 then Class = Cat1 else Rule: 6 if BMI = 28.4 then Class = Cat1 else Class = Cat2 else Rule: 7 if BMI = 22.9 then Class = Cat1 else Rule: 8 if BMI = 27.6 then Class = Cat1 else Rule: 9 if BMI = 29.7 then Class = Cat1 else Rule: 10 if BMI = 27.1 then Class = Cat1 else Rule: 11 if BMI = 25.8 then Class = Cat1 else Rule: 12 if BMI = 28.9 then Class = Cat1 else Rule: 13 if BMI = 23.4 then Class = Cat1 else Rule: 14 if BMI = 30.5 then Rule: 15 if TSFK = 18 then Class = Cat2 else Class = Cat1 else Rule: 16 if BMI = 26.6 then Rule: 17 if TSFK = 18 then Class = Cat2 else Class = Cat1 else Rule: 18 if BMI = 32 then Rule: 19 if TSFK = 15 then Class = Cat2 else Class = Cat1 else Rule: 20 if BMI = 31.6 then Class = Cat2 , Cat1 else Class = Cat2 The twenty decision rules are for the 3rd partition of the dataset. The number of rules for this cluster is higher than the other two clusters discussed. The visualization is important tool which provides the better understanding of the data and illustrates the relationship among the attributes of the data. For the visualization of the clusters 2D scattered graphs are drawn for all the clusters. We are presenting the four 2D scattered graphs of four different clusters of different partitions. Figure 3. 2D Scattered Graph between NTP and DPF attributes of Diabetes dataset The distance between NTP and DPF attributes of Diabetes dataset varies at the beginning of the graph but after some interval the distance becomes constant. Figure 4. 2D Scattered Graph between DBP and AGE attributes of Diabetes dataset There is a variable distance between DBP and AGE attributes of the dataset. It remains variable throughout this graph. Figure 5. 2D Scattered Graph between TSFT and BMI attributes of Diabetes dataset The graph shows almost constant distance between TSFT and BMI attributes of the dataset. It remains constant throughout the graph. Figure 6. 2D Scattered Graph between PGC and 2HIS attributes of Diabetes dataset There is a variable distance between PGC and 2HIS attributes of the dataset. But in the middle of this graph there is some constant distance between these attributes. The structure of this graph is similar to the graph of figure 5. 5. Conclusion It is not simple for all the users that they can interpret and extract the required results from these clusters, until some other data mining algorithms or other tools are not used. In this research paper we have tried to address the issue by integrating the K-means clustering algorithm with the Decision tree (ID3) algorithm. The choice of the ID3 is due to the decision rules in the form of if-then-else as an output, which are easy to understand and help to take the decision. It is a hybrid combination of supervised and unsupervised machine learning, using intelligent agent, called a LIAgent. The LIAgent is helpful in the classification and prediction of the given dataset. Furthermore, 2D scattered graphs of the clusters are drawn for the visualization.

Effect of Weather on Construction Labour Productivity

Effect of Weather on Construction Labour Productivity Effect of Hot and Cold Weather on Construction Labour Productivity EXECUTIVE SUMMARY The research deals with the variation of labour productivity in extreme weather conditions in India. As we head more and more into the rural areas for construction the labourers are faced with unprecedented weather conditions as extreme cold and heat stress combined with other geographical factors. We compare the difference in productivity achieved in normal weather conditions with extreme cold locations as Kargil and hot regions as Ahmedabad. Further this is compared by the standards set by IS 7272 for ideal productivity. After studying the results recommendations are done specifically for domestic projects considering the situations prevailing in India and future weather uncertainties. CHAPTER 1: INTRODUCTION BACKGROUND OF THE STUDY An Industry ultimately thrives upon the physical input put in by the labourers and the construction industry is no exception, in fact the construction industry is one of the most labour dependent industries operating in India. It is the groundwork of the labourers, which ultimately runs this industry. Though lot of work has already been done to optimize labour productivity around the world, majority of the projects still stay behind schedule and are completed with cost and time overruns, though this might be due to multiple reasons but labour productivity still dominates the final output. With the increase in population the infrastructure and public wealth construction is being pushed more and more into the rural areas which are untouched in the last century. Thus are the studies, which prevailed in earlier times about the productivity, as these new regions put up new challenges of the working environment. Not much has been done to check the productivity changes in these regions, this often results in variation from the IS values which should be attained ideally. OBJECTIVES Our objective of this research is to study and outline the factors, which are, determinable in altering productivity outputs in adverse weather. To compare the factors stated in IS 7272 with actual ground data for productivity achieved on construction site and suggest methods to counter. This would further transform into meeting project milestones in time. SCOPE OF WORK The research work is based on actual site data collected from different construction sites in India. It aims to study the variations observed if any from the standards in the IS 7272 for labour productivity and the reasons leading to these changes. It covers both extremes of the temperature in its study hot and cold regions, finally suggesting the measures to be taken to optimize labour output in extreme weather conditions. RESEARCH METHODOLOGY The methodology adopted to prepare this report ranged from reviewing work previously done in these areas of labour productivity along with site visits and collection of data. We reviewed papers from journals and tried to draw a few conclusions by correlating the studies and common factors in the research papers. Data collection was done by visiting sites of projects under progress across India. For the sake of comparison with other site data to keep maximum parameters same we worked on productivity for the activities which were common to both the sites. Data was collected over different periods of duration with respect to every project and analysed for their productivity calculations. These calculations were further compared with the standards set by the IS 7272. Further we attempt to outline the factors which may be the probable cause for the deviation and suggest remedial measures to counter them. LIMITATION OF STUDY Since the data was collected from sites in India and the observations made were from Indian gang of labourers, the results and study are limited to Indian subcontinent. Also ideally for comparison there should be similar situation of work with less variables such as work type and other conditions other than the weather, but due to the limitation of the projects the sites were not executing similar projects, thus the data cannot be said to be 100% precise. Although we have put in our best efforts to counter this by selecting similar activities of execution. Furthermore due to the limitation of availability of data the results achieved cannot be said to depict the conditions prevailing all through India as more work is awaited on this topic in India. CHAPTER 2: LITERATURE REVIEW To study the work previously done research in this area we studied numerous papers published on Productivity from various journals across the globe. Though it was out observation that the research work was more or less biased to the productivity concerns due to increasing temperature, and less about the colder conditions. India being a tropical country experiences both extremes of the climate through the year, thus we review work done in colder regions too, a few of our findings are as follows. Tord Kjellstrom, PhD; R. Sari Kovats, MSc; Simon J. Lloyd, MSc; Tom Holt, PhD; Richard S. J. Tol, PhD studied the changing pattern of temperatures across the globe, which will ultimately lead to a global climate change and an increase in heat load and will degrade the productivity of workers in the coming future. It was a region-based study where they established a relationship between the rise in temperature and loss of productivity as a percentage drop. The study was localized for a much accurate assumption, overall there was a loss in productivity with the increase in temperature. Meglan, Meglan Company Ltd. outlined in their publication Construction Claim Topics the loss of productivity due to effects of weather the reasons for loss. They subdivided their study into three subcategories Low temperature and Wind chill, high temperature and humidity Wind only effects. They stated that the loss of productivity occurs In all three conditions due to different factors in each conditions. They stated that a drop of as much as 50 % can be observed in extreme situations. They established a fact that humidity also played a detrimental role in the loss as at the same temperatures the change in productivity was evident with the change in humidity levels at the site. Adham Shahin, Simaan AbouRizk, Yasser Mohamed and Siri Fernando developed a simulation based framework for quantifying the cold weather region impacts on construction scedules, the framework composed of components that help in understanding and simulating construction projects. The basic aim of this framework is to enable the researcher to quantify the impact of weather alterations on project schedule. The process involves the creation of a basic discreet simulation model to simulate the activities on site. An article published in THE Monitor | Climate stated the economic impact of the increasing temperature uncertainty across the globe, they forecasted the future developments for the year 2030 where the prediction is of 450 hotspots from the 55 existent today. In 2030 the expected loss is 413 billion USD. In their country level impact analysis they have plotted a country wise loss index in which India comes under the Acute category forecasting a loss of 450,000 million US $ additional economic cost in 2030 only due to increase in temperature of working environments of labourers. They suggest adaptation to the new environment is the most cost effective measure, which can be taken against this. Yildirim, Kemal.à ¯Ã¢â€š ¬Ã‚ ª Koyuncu, Cuneyt. Koyuncu, Julide. In their paper does temperature affect labor productivity: cross- country evidence published in the journal Applied Econometrics and International Development. They established a relation between temperature and labour productivity and plotted a graph to depict it. The study done over 111 over a period of several years’ states that increase in temperature has a negative effect on labour productivity. Pieter Diedericksà ¢Ã¢â€š ¬Ã‚ ¨ Senior Project Director, Oil Sands Projects, Petro-Canada, Canada in his study OPTIMIZING WINTER CONSTRUCTION studied the effects of cold weather on construction industry. He used temperatures below 200 F as the basis of cold temperature. He stated that an average loss of labour productivity due to cold temperature is almost 50%. Thomas suggested the use of annual cycles to schedule activities most affected by weather. He suggested remedial measures as use of wind protective armour and setup of machinery when the conditions are adverse instead of physical labour-intensive work. Karin Lundgren1*, Kalev Kuklane1, Chuansi Gao1 and Ingvar Holmà ©r1 presented a paper on Effects of Heat Stress on Working Populations when Facing Climate Change, Their study relates o heat stress on workers and how it negatively impacts the productivity overall. They suggested the ideal temperature for physical work as 370C, any more beyond these results in physiological effects in the human body reducing its capacity to perform productively. CHAPTER 3: LABOUR PRODUCTIVITY THEORY WHAT IS LABOUR PRODUCTIVITY Labour productivity as defined as the amount of output received by the number of man hours or man days input by the worker. Labour productivity optimization is needed to get the optimum output from a projects workforce, thus is also termed as workforce productivity. In the construction industry which is predominantly labour intensive this factor plays a determinable role in deciding the fate of the project itself. And in a country like India where there is cheap and efficient labour available, if used properly the production costs can be brought down drastically, be it of any industry in this scenario. Labour productivity can be measured in number of ways depending on each industry but the thumb rule for calculation of labour productivity is Labour productivity = volume measure of output / measure of input use WHY MEASURE LABOUR PRODUCTIVITY? In the construction industry most of the contractors take careful note of variation in local and regional weather patterns, the norms andtrends, and based on these they schedule their construction projects. Well planned construction schedules are prepared to take advantage of favorableseasonal, local, or regional weather patterns and avoid the unfavorable ones. Thus, when a Project doesn’t start on time, or it gets delayed during the time of execution weather may become an all important factor in the overall delay, reducing planned productivity and efficiency. Most of the construction contracts allow excusable delay and time extensions at the time of abnormal or unusual weather conditions. When this kind of delay is encountered it incursenormous losses in the number of extra man hours spent, and further delays of the project and work. Hot weather and cold weather create efficiency and productivity losses which can be explained separately as follows: Cold Weather Workers productivity drops with the fall in temperature. The productivity of the manual labours drops gradually during extreme temperature conditions. This productivity losses can be best quantified by comparing productivity from cold weather effected work periodsto that measured during normal work periods, thereby determining the difference. It only requires man-hours data and weather data (can be obtained from internet), sorted by date. The man-hours and temperature data are entered into a spreadsheetprogram by date any their productivity is calculated. Hot Weather Just as the productivity decreases in cold weather, same losses also occurs when the temperature rises above twenty nine degree centigrade to thirty four degree centigrade and beyond. The inefficiencies can only be quantified by actual measurement of productivity in hot weather and then comparing with normal weather productivity. TYPES OF CONSTRUCTION LABOUR A construction project is dependent on different levels of work done by the workers. Thus generally the division is among the levels of labourers. Namely Skilled Labor Semi Skilled Labor Unskilled Labor SKILLED LABOUR PRODUCTIVITY Skilled Labours constitute operators, foremen, and machine operator’s i.e the labourers with give a higher output of work per hour of input. The skilled labourers usually are head labourers for a gang, operators for special equipment and are highest paid in the lot. SEMI SKILLED LABOUR PRODUCTIVITY Semiskilled labours are mediocre paid workers with somewhat lesser skills as compared to skilled ones, their productivity outputs are higher per hour though compared to unskilled labourers. Carpenters, Masons, Fixers constitute this list of semi-skilled labours UNSKILLED LABOUR PRODUCTIVITY This is the largest clan of labourers who are good for maximum physical exertion, and it’s their tireless efforts which ultimately proves detrimental in the project being on schedule. Their productivity depends on how efficiently they are managed by their foremen. It is this clan of people we need to optimize for the drastic change in overall timing schedules. DIFFERENT MODELS OF PRODUCTIVITY MEASUREMENT To serve different purposes there are different measures of productivity, one can choose the method which serves their purpose. Thomas et al. defined different models of measures to measure productivity which are as follows: Economic models The department of Commerce, and other governmental agencies use a productivity definition in the following form: Equation (a) Total factor productivity (TFP) =Total output / Labor + Materials + Equipment + Energy + Capital Project-specific models A more accurate definition that can be used by governmental agencies for specific program planning and by the private sector for conceptual estimates on individual projects is: Equation (a) Productivity=Output/ Labour+ Equipment + Materials Equation (b) Productivity = Square feet / rupees Design professionals use productivity data in this form. Activity-oriented models A contractor is more likely to define productivity using a narrowly defined version of(a)and(b), where the units of output are specific for generic kinds of work. Typical units are cubic yards, tons, and square feet. Various related activities, such as formwork, steel reinforcement, and concrete placement, can be combined using the earned-value concept (Thomas and Kramer, 1987, cited in Thomas et al., 1990, p. 706). Productivity is expressed as units of output per Rupee or work-hour. At the project site, contractors are often interested in labor productivity. It can be defined in one of the following ways (Thomas and Mathews, 1985 cited in Thomas et al., 1990, p. 707)[5]: Equation (4) Labour productivity=Output/Labour cost or Equation (5) Labour productivity=Output/Work-hour There is no standard definition of productivity and some contractors use the inverse of Eq.(5): Equation (6) Labour productivity=Labour costs or work-hours / Output Eq.(6)is often called the unit rate. Still other contractors rely on the performance factor as a measure of productivity Equation (7) Performance factor=Estimated unit rate / Actual unit rate FACTORS AFFECTING LABOUR PRODUCTIVITY Identification and evaluation of factors that impact labour productivity has become important to determine the key elements that can be changed to bring about optimization of the entire process of work. Due to the complexity of work involved one factor alone cannot be held responsible for the change rather it is a combination of multiple factors which results in the desired/undesired change in the productivity of an individual or the project as a whole. Some of the key factors are listed as follows. Work Schedule Labour Pool Native Place of the gang Temperature Type of project Project Location Time Allocated for activities Design factors Execution plan factors Material factors Equipment factors Labour factors Health and safety factors Supervision factors Working time factors Project factors Quality factors Financial factors Leadership and coordination factors Organization factors Owner/consultant factors External factors

Monotremes and Electroreception :: Monotremes and Electroreception

Abstract Through their evolution, monotremes have developed several characteristics that make them unique from most other mammals. The focus of this paper lies on the electroreceptive capabilities of monotremes. Electroreception of monotremes is partially comparable to that in fish. The bill of the platypus, Ornithorhynchus anatinus, and the beaks of the echidnas, Tachyglossus aculeatus and Zaglossus bruijni, all contain three types of receptors: push-rod mechanoreceptors, serous gland electroreceptors, and mucous gland electroreceptors. The information collected by these receptors is sent to the somatosensory cortex. The platypus, whose electroreceptive system is more complex than that of the echidna, uses electroreception to capture prey and is the only mammal know to so. (It is not yet known if the echidna uses electroreception to capture prey.) Introduction Monotremes have fascinated scientists since their discovery in 1799 (Moyal 4). The isolation of monotremes in Australia has allowed monotremes to evolve several unique characteristics. One newly discovered mystery of these animals is their electroreceptive capability. This discovery brings up many questions. How did monotremes evolve this elaborate sensory system? What do these electroreceptors look like, and how do they function? How do monotremes perceive this "sixth sense?" This paper will attempt to address these questions. Monotreme Diversity Order Monotremata is split into two families and three species. Ornithorhynchus anatinus, commonly called the platypus, can be found in eastern Australian rivers and creeks from Queensland all the way down the coast and across the Bass Strait into Tasmania (Moyal 18). The platypus is not a large animal. Males, which can weigh 2.35 kg and reach .56 m in length, are larger than the females (Dawson 9-10). The platypus swims with its mouth, ears, and eyes shut (Dawson 10). O. anatinus sifts the bottom for food, which is mainly non-insect invertebrates, crustaceans, worms, some vertebrates, and benthic larvae of various insects (Dawson 10). The two other surviving species of monotremes are Tachyglossus aculeatus, the short-beaked echidna, and Zaglossus bruijni, the long-beaked echidna. Echidnas range throughout Australia and New Guinea as well as islands adjacent to both land masses (Collins 17). Both species have characteristic modified hairs that function as spines (Dawson 10-12). T. aculeatus is a stocky animal (3-5kg) with a small head and pointed snout (Dawson 10-11). Z. bruijni is larger than T. aculeatus (~10kg) and has a downward curving snout (Dawson 11-12). The snouts and tongues of T. aculeatus and Z. bruijni are ideal for diets of termites, ants, and earthworms (Dawson 10-12).

Book Review: ATLAS SHRUGGED by Ayn Rand   Ã‚  Ã‚  Ã‚  Ã‚  Taggart Transcontinental is not to be excluded on the effects of declining economic situations experienced by the whole country. Dagny Taggart, the vice president in-charge of operations, upon her visit to the Rio Norte Line to inspect the damages it maintains, goes straight to her brother’s office and reports that the line needs immediate attention and for that she has already ordered Rearden Metal to be used for that line. Jim denounced her decisions and actions not just because she does not have authority to make those orders but also Rearden Metal is not yet tried before by others. Dagny’s plan to rebuild this important line is held back when most of the corporation’s business contacts and suppliers as well as own personnels are suddenly leaving and mysteriously vanishing. Meanwhile, Dagny’s brother Jim uses his political influence to save his railroad and thus the Anti Dog-Eat-Dog Rule was approved to rid of competitions in railroa d, specifically Taggart’s competitors. Dagny’s plans of rebuilding were further hampered when the State Science Institute publicly deprecates Rearden Metal although this is the best type of metal ever formulated and invented. Focused to rebuild her line, Dagny decides to start her own company where she would take all the risks and responsibilities of using Rearden Metal, and once the line was built, she would then have to return the line to Taggart Transcontinental. Her decision was not a disappointment and proved to be a surprising success. Then, a new set of law called Directive 10-289 was passed and includes a decree that all patents or inventions are to be taken over by the government for public use. Dagny quits and retreats to an old family house in the mountains. She was followed there by Francisco where he now tells her everything he has been up to. However, upon hearing news about a new railroad accident, she rushes back to her office and takes over again. Then in pursuit of the scientist she has assigned to rebuild a motor that can transform static energy to kinetic energy that she and Hank have discovered, she crashes into an unknown location where all the missing great minds are living. They are on strike describing it a strike of the mind. There she came to know the real John Galt and was able to live with him for a month.

The Rapid Growth of Online Social Media Networks

Social networking used to link and portion information with friends.People may utilize societal networking services for dii ¬Ã‹â€ erent grounds to web with new contacts, reconnect with the friends, maintain the relationships position, for concern or undertaking work related, take participate in treatments on the many subject, or merely hold get together meeting and interaction with other take parting users. [ 1 ] .There are figure of users on SocialNetwork and Twitter. LinkedIn has positioned itself as a professional networking site proi ¬?les include resume information and groups are created to portion many inquiries and thoughts with other users in similar i ¬?elds. Unlike traditional personal home pages people in these societies publish non merely their personal properties, but besides their relationships with friends.It may do the privateness misdemeanor in societal webs [ 3 ] .Information privateness is needed for users. Existing techniques are used to forestall direct revelation of sensitive personal information.Here the focal points on societal web informations classii ¬?cation and inferring the persons private information. More private information are inferred by using corporate classii ¬?cation algorithm. The system heighten how the on-line information of societal web is used for anticipation some person’s private property that a user/person are non interested unwrap these property to other users ( e.g. gender identii ¬?cation, sexual orientation ) .For illustration in an oi ¬?ce people connect to each other because of similar professions. Therefore it is possible that one may be able to deduce someone’s property from the properties of his/her friends. In such instances, privateness is indirectly disclosed by their societal dealingss instead than from the proprietor straight. This is called personal information escape from illation [ 10 ] . The rapid growing and ubiquitousness of on-line societal media services has given an impact to the manner people interact with each other. Online societal networking has become one of the most popular activities on the web. Social web analysis has been a key technique in modern sociology, geographics, economic sciences, and information science.The informations generated by societal media services frequently referred to as the societal web informations. In many state of affairss the informations demands to be published and shared with others. Social webs are online applications allow their users for connexion by dii ¬Ã‹â€ erent linktypes [ 3 ] . As portion of their professional web. Because of users specify inside informations which are related to their professional life.These sites gather extended personal information societal net- work appli- cation suppliers have a rare chance direct usage of this information could be utile to advertizers for direct selling. Print informations for others to analyse even though it may create terrible privateness menaces or they can keep back informations because of privateness concerns even though that makes the analysis impossible. For illustrations concern companies are analyzing the societal connexions in societal web informations to bring out client relationship that can benei ¬?t their services and prod- uct gross revenues. The analysis consequence of societal web informations is believed to potentially supply an alternate position of real-world phenomena due to the strong connexion between the histrions behind the web informations and existent universe entities. Social-network information makes com- merce much more proi ¬?table [ 7 ] . On the other manus the petition to utilize the informations can besides come from 3rd party applications embedded in the societal media application itself. For case, societal sites has 1000s of 3rd party applications and the figure is grow- ing exponentially. Even though the procedure of informations sharing in this instance is inexplicit the informations is so passed over from the information proprietor ( service supplier ) to dii ¬Ã‹â€ erent party ( the application ) .The informations given to these applications is normally non sanitized to protect users privacy.Desired usage of informations and single privateness presents an chance for privateness continuing societal web informations excavation. That is the find of information and rela- tionships from societal web informations without go againsting privateness. So utilizing classii ¬?cation i ¬?nd sensitive informations and take it from informations set and supply extremely sanitize dataset [ 1 ] . Although OSNs are rather utile in dii ¬Ã‹â€ erent sense, there has been some consid- erations about privateness of users in such services. OSNs are big datastores of personal information. This information is valuable in the sense that by statistical analysis it is possible to pull out the penchant of users based on dii ¬Ã‹â€ erent standards such as gender and matrimonial position. Such analysis can so be used for advertisement and research intents [ 5 ] . MET’s Institute of Engineering 2 Preventing techniquesused for profile informations bar illation onslaught on societal web Third-parties provide targeted advertizement to increase their commercial gross utilizing the societal platform and custom-make their publicities precisely based on the penchants of visitants and increase their opportunities on marketing [ 1 ] . OSN suppliers such as Facebook province that they will non manus private information to these third- parties. However there has been many contentions about escape of sensitive information to third parties where OSN suppliers handed private user information along with ego placing information. A recent probe by the Wall Street Journal showed that personal ID of Facebook users was being transmitted to third party advertizement and tracking companies along with their personal involvements which was against the promises made by Facebook [ 6 ] . This is where concerns are raised about the privateness of OSN users. The chief privateness concern is that members might non be willing to expose their proi ¬?le information to everyone indoors or outside a web. Peoples need control over their personal information and how it is being shown on the web. In OSNs users provide their electronic mail reference, exposure, friends, instruction, calling background, relationship position and activities such as noticing. For assorted grounds one might be willing to conceal them from certain people. Reasons such as safety, separation of work environment and personal life are among them. If the information is public to everyone it can do jobs such as losing a occupation. Furthermore it can be collected and used for commercial intents without the consent of users [ 7 ] , [ 8 ] . The privateness scenes normally does non to the full let concealing friendship links and groups ai ¬?liations and the connexion between people and groups are publically seeable. Such links and ai ¬?liations can take to information escape and expose high sum of information. In add-on many users do non protect their proi ¬?les from aliens and the web would be a mixture of public and private proi ¬?les [ 13 ] . As a consequence while an single protects his proi ¬?le utilizing the privateness scenes, it is possible that a big fraction of his friends have an unfastened proi ¬?le which contains information about him including the friendly relationship nexus, remarks and so on. Besides even if there are no direct information about a individual in his friends, by statistical analysis it would be possible to deduce some properties for a user even if he has a private proi ¬?le which is the subject of this System [ 14 ] , [ 15 ] . The end of this System chiefly highlights how it is possible to deduce and retrace private properties of OSN users based on friendship links and personal inside informations. Using chance theoretical accounts and informations excavation attacks such as Naive bays larning, it is shown that with certain possibilities it would be executable to deduce private properties of users. MET’s Institute of Engineering 3 Preventing techniquesused for profile informations bar illation onslaught on societal web To see the consequence on a existent dataset, a well-known Facebook OSN, Proi ¬?le information is col- lected and used. Analysis of system shows that it is possible for an active OSN member to to the full protect its privateness by remotion of sensitive properties from proi ¬?le informations or from dataset before let go ofing to third party [ 1 ] , [ 11 ] . 1.1 Area of Dersertation Social webs are considered as online applications that permit the users to link by manner of assorted nexus types. Based on the provided inside informations, these webs let people to name inside informations about themselves that are appropriate to the basicss of the web. Some site is a common usage of societal web, hence single users list their preferable activities, films and books. Conversely a professional web such as LinkedIn, users specify inside informations which are suited to their professional life.These sites gather extended personal information and therefore societal web application suppliers have a rare opportunity of direct use of this information that could be utile to advertizers for direct marketing.For forestalling illation onslaught proposed system is used and it better the classii ¬?cation truth of system by utilizing Naive bays classii ¬?cation.

The i ¬?rst is that to find whether a individual is †conservative† or †liberal† on the footing of user proi ¬?le information. MET’s Institute of Engineering 6 Preventing techniquesused for profile informations bar illation onslaught on societal web Privacy concerns of persons in a societal web can be classii ¬?ed into two classs: privateness after informations release, and private information escape. Cases of privateness after informations release involve the identii ¬?cation of specii ¬?c persons in a information set subsequent to its release to the general populace or to paying clients for a specii ¬?c use or 3rd party for their advertisement work. By deducing the sensitive property like gender, matrimonial position such personal information of user proi ¬?le is used for dii ¬Ã‹â€ erent type of attack.Here aims of system is privacy concern as concealing the user’s personal inside informations from exterior users means from 3rd party, so information misusage are avoid.

A Good Man Is Hard to Find: Irony

â€Å"A Good Man is Hard to Find† In the short story, â€Å"A Good Man is Hard to Find† there is irony all through the pages. It shows how you should follow your gut instinct when you think you shouldn’t go somewhere, when you know something bad is going to happen. In the story it also talks about how the grandmother wore her nice clothes in case of an accident, she wanted to look like a lady in case anything bad was to happen. The grandmother was constantly talking about the good in people, but was she a good woman? The first bit of irony the story throws at the reader is on the first page when the grandmother is talking about how she doesn’t want to go to Florida because that’s where the Misfit is headed. As the grandmother is trying to get her son Bailey to listen as she says, â€Å"The Misfit is aloose from the Federal Pen and headed toward Florida and you read here what it says he did to these people. Just you read it. I wouldn’t take my children in any direction with a criminal like that aloose in it. I couldn’t answer to my conscience if I did† (O’Connor 281). Now I don’t believe that the ironic twist is that the misfit was headed to Florida just like the family, I believe that the twist is that the Misfit just so happen be on the same dirt road that the grandmother asked her son Bailey to turn down later on in the story. The grandmother wanted to turn down this dirt road in Georgia because she remembered an old plantation house she had visited when she was younger. After turning down the road she then remembered that this was not the road at all, the old plantation house she had remembered was in Tennessee, not Georgia. The second major ironic twist that stood out to me was how the grandmother wore good clothes to go on a road trip, â€Å"In case of an accident, anyone seeing her dead on the highway would know at once she was a lady† (O’Connor 282). The grandmother wore a navy dress with a straw hat that had white violets on it. Indeed the grandmother was dressed like a lady, but did she act upon it at all times? I think she did just that, I believe she acted like a lady but was not truly one. Grandmothers cat caused Bailey to have an accident. †¦as the grandmother limped out of the car, her hat still pinned to her head but the broken front brim standing up at a jaunty angle and the violet spray hanging off the side† (O’Connor 287). At this point is when I believe that the grandmother acts as if she is a lady. If she was a true lady then maybe her clothes would not have been messed up, or there wouldn’t have been an accident at all. But there is still that piec e of thought about how the grandmother knew to dress in case of an accident. The final bit of irony is how the grandmother kept talking about good men, and how they are hard to find. When the family stops at the diner to eat she talks to Red Sammy and his wife about how hard good men are hard to find, but then she also tells Red Sammy that he is a good man because he let a couple of men charge gas. Red Sammy’s wife says there isn’t no one that she can trust, â€Å"‘And I don’t count nobody out of that, not nobody,’ she repeated, looking at Red Sammy† (O’Connor 285). After they wreck a car shows up with The Misfit and his two side kicks in it, who turn out not to be good men. The grandmother realizes real soon that the man is The Misfit, she recognized him from the picture in the newspaper. Soon after arriving Bobby Lee takes Bailey and his son John Wesley into the woods to kill them. The grandmother went on about how the Misfit could be a good man, and how he should pray. The Misfit told her that his family was good people, he just wasn’t. Soon Bobby Lee and Hiram took the childrens mother, June Star, and the baby to the woods to meet up with the boys. The grandmother then realized that she must think of something soon, because she would be next. They started talking about Jesus and how he did or didn’t raise the dead. The Misfit said that if he didn’t know but if he would have been there he would have known better and wouldn’t be the way he is now. â€Å"Why you’re one of my own babies. You’re one of my own children! † (O’Connor 293). After the grandmother said that she touched him on the shoulder and the Misfit turned around and shot her three times in the chest. This was a great short story for irony, because the grandmother was correct about most things. The grandmother knew not to go towards Florida because The Misfit was headed that way after escaping from the pen. She was right about dressing like a lady in case of an accident, because indeed there was an accident, but she caused the accident by bringing her cat along without anyone knowing. Then there is speak of a good man, is there any such thing? Red Sammy’s wife wouldn’t even think of him as a good man, if your wife doesn’t believe you are no one really can. The Misfit comes along and talks to the grandmother for a while about good people, while doing so shoots her family then her dead. ‘â€Å"She would have been a good woman,† The Misfit said, â€Å"if it had been somebody there to shoot her every minute of her life†Ã¢â‚¬â„¢ (O’Connor 293). This goes with my assumption that the grandmother was just acting like a lady, and The Misfit even saw through her lies.
