Othello - Iago Character Analysis Essay - 772 Words

Iago, in Shakespeares Othello, is a deceiving character because he tells lies in order to get what he wants. He interacts with people only to manipulate them, but most importantly he never reveals his true feelings or motives. Iago might say things that suggest what his motive is, but he soon contradicts himself with another suggestion making it extremely difficult to understand him. Although Iagos true motives cannot be determined, some motives could be jealousy, the enjoyment of seeing people suffer, or power. Iagos jealous of Othello and Cassio because he thinks that both of them slept with his wife, Emilia. In Iagos first soliloquy at the end of act 1, Iago says that Othello might have slept with his wife and even though this is a†¦show more content†¦Iago is a very clever person and he enjoys seeing how idiots make fools of themselves. One of these idiots is Iagos buddy, Roderigo. Roderigo is a typical wealthy, Venetian aristocrat who is madly in love with Desdemona and he has given Iago the task of helping him woo her. Iago uses this to his advantage, even though Iago uses Roderigo to ruin Cassio and Othello, he gets some amusement by watching Roderigo prance around and go nuts over Desdemona. Iago also finds it funny when Roderigo wants to go kill himself after he finds out that Desdemona married Othello. There are multiple times throughout the play where Roderigo should have known that Iago was just using him for money and some laughs and since Roderigo doesnt pick up on this, Iago can use Roderigo to his advantage. Power is probably the most important motive. Iago is very conniving and clever and he can use this to manipulate people. It is clearly seen that Iago thrives for power because he loves manipulating people so that they doe exactly what he says. He does this to Roderigo many times, like when Iago tells Roderigo to give him all of his money and when he convinces Roderigo to kill Cassio. He even controls Othello to the point that Othello suspects his wife and decides to kill her. Iagos thirst for power is also seen when Cassio is appointed to be Othellos lieutenant because this was, supposedly, the basis for his revenge. He really wanted to be lieutenant because it is aShow MoreRelatedThe Character Analysis Of Iago Of Othello1075 Words   |  5 PagesAt first glance, Iago of Othello can appear to have little motivation for his destructive tendencies; however, when viewed through the lens of antisocial personality disorder, his incentive takes on a twisted internal logic.

My Theory on Personality Free Essays

My Theory of Personality Personality refers to a combination of long-lasting and distinctive behaviors, thoughts, motives, and emotion that typify how we react and adapt to other people and situations. (Plotnik, 2012) Many psychologists, like Freud, theorize that it is a combination of many factors that affect the personality. Many of these factors ranging from early childhood development and unconsciousness to rewards and punishments. We will write a custom essay sample on My Theory on Personality or any similar topic only for you Order Now I have chosen four concepts that I believe contribute the most to the development of the personality and will explain why. The concepts I have chosen to be part of my very own personality theory are: childhood experiences, interpretation of experiences, and observable behavior. Alfred Adler, an Austrian medical doctor and psychologist, once said that we develop our desires and drives during our childhood then our whole adulthood becomes affected by these childhood experiences. People keep striving during their adulthood to fulfill the desires they have developed during childhood. (Radwan, 2008) Childhood experiences are the first lessons you learn, the first observations you see, and are what I believe to be the basis of personality in adulthood. For example, if a child grows up with an overprotective family, she/he will learn to fear strangers and have a lot of insecurities. But in adulthood they will have to deal with that fear, in such a way that it might transfer to another fear like a fear of taking risks or trying new things. Growing up, there are always situations when you have to meet new people or interact with strangers, and sooner or later you get over the insecurities you have about meeting new people and become friendlier, or you keep your anthropophobia and become very isolated. Personality traits you learn at a young age sticks with you throughout your life even if you forget about them, you’re unconscious mind still puts them in to effect on a daily basis. Interpretation of experiences very from person to person. â€Å"Kids need to feel badly sometimes,† says child psychologist David Elkind, professor at Tufts University. â€Å"We learn through experience and we learn through bad experiences. Through failure we learn how to cope. † Some people might take overbearing parents as a sign of love and affection. While on the other hand a different person might see it as suffocating and annoying. Depending on how they interpret these situations of over-protection by their parents will build on their personality. (Marano, 2004) The child who sees the overbearingness as love will embrace and project it as an adult. But the child who sees the protectiveness as suffocating will want to take more risks and be more outgoing as an adult. A real question I have is why do we interpret these situations the way we do. Most of the time I realize the way I react to certain situations is the same as the way my mother would have reacted. Maybe it is because we spent a lot of time together in my teen years. Observable behavior is basically what you see people do and how they act. There is a phase people say to one another that, in its simplest form, means take note and execute. â€Å"Pay it forward†. Paying it forward is when you notice someone going out of their way to do something nice for you. And in return you do the same for someone else. In a way it is supposed to start a chain reaction and sooner or later more and more people will be kinder to strangers. But after a while the chain end due to someone not paying it forward. Maybe they didn’t notice or they were not paying attention. And when it comes time for them to pay it forward they think nobody has done it for them, so why should they do it for someone else? So, they do not help this person out. That is observable behavior, people learn by watching, and it can change them to be friendlier or ruder. In my theory of personality, childhood experiences, interpretation of experiences, and observable behavior all contribute to it. Each has its very own contribution towards a person’s personality. Weather it is from early childhood and how the child is treated or young adulthood observing your environment and learning from your environment. Even how you see certain situations, you can see the positive side or the negative side. Just one behavior cannot be the only reason for a person’s personality. It takes many different events to establish it. How to cite My Theory on Personality, Essay examples

Effective Mentoring The Community Setting †Myassignmenthelp.Com

Question: Discuss About The Effective Mentoring The Community Setting? Answer: Introduction The case study here reflects on different challenges that a child faces in the overall developmental processes such as cognitive and social development. The child named Jack mentioned in the case scenario faced problems in toilet training and speech development. Thus in the following essay, the roles of the health nurses will be discussed by adopting theories as examples in developing the cognitive and social skills to help children between the ages of two and five years in their proper development taking Jack as example in developing his toilet training skills and speech development. Role of nurses and midwives in child development The health nurses and midwives play a vital role in the business development stages of the child through proper take care. In this present case scenario, it discusses about a child named Jack, 3 years old who had been attending a day care center. Jack was found to experience difficulties to master skills in toilet training and also in speech development. This bothered his mother as the other children of his age had already mastered the skills. Thus, based on this problems, there warranted a proper focus on the social and cognitive development through different theories that effectively contributes towards the personal development of the child. With this respect, the nurses could play a major role in the toilet training and also can also encourage the child to participate in different playing sessions along with other kids in the day center. Child attachment The midwives are found to play a potential role in child attachment development which could be explained by Bowlbys attachment concept (Sarsfield, 2014). He in this theory stated that every child came in this world with certain emotions of attachment that were preprogrammed which helps them in their survival. Any kind of separation between the parents and the child inculcate feelings of getting unsecured and anxiety within the child (Hechter, 2017). In the present case study as the mother was a working person was not able to spend enough time with her child. Thus the prolonged detachment of the child from his mother could have negatively affected the development of cognition followed by feeling lonely and unsecured within the child. Thus to combat this kind of situation interactive sessions should be arranged to initiate the learning process via digital platform. According to DeVellis (2016), this learning session develops increased interest within the child followed by an assistive framework to develop the cognition. Accounting to the theory the mother should also involve more actively with her child that would help the child in developing the communication and learning prospects. Cognitive development The nurses can effectively help the child in developing the cognitive behaviour and the development of the cognition in the child could be explained by the Piagets theory of cognitive development (Harvey Park, 2015). Jean Piaget believed that the way a child views the world is strongly influenced by age, maturation and experience. According to his theory, the 3 years old child can be placed under the preoperational stages of cognitive development (Moore, 2014). This stage reflects the ability of the child to imagine with strong intuition, although have difficulties in processing abstract and complicated thoughts. He also explained that the child should be capable enough to properly express his thoughts through proper use of grammatical words and syntax. But in this case, Jack faced difficulties in speech that made the expression process problematic in him. In this context, the nurses should provide a deliberate assistance by considering the concerns of the child by breaking down the difficult words into simple terms that were clear to him. The nurses should encourage him continuously to speak more often as much as possible and also provide a proper friendly environment to support him in developing the cognition (Pritchard Gidman, 2012). Social development Jack in this case was also facing trouble in toilet training and communicating clearly thereby reducing the social etiquette development. One of the theories that explain the social development is Eriksons social development model. This theory entails the psychosocial problems of the child. At this stage, the child undergoes mixture of feelings comprising of autonomy versus shame and forbids from the self management of daily activities of life. Thus involving the child actively in the process of care planning would generate more excitement and curiosity within the child (Trollvik et al., 2013). Apart from this, the nurses could provide increased autonomy in child by incorporating proper decision making within the practice. This type of compassionate environment would help the child to be more proactive and more expressive verbally (Howlin et al., 2014). Thus the nurses could effectively impact the overall development of the child by advocating policies for increased appropriate home, nutrition and learning (Behrman Urza, 2013). In the cognitive development of the child nourishment had been found to play a major role (Bernier et al., 2012). In addition, the nurses assisting the parents in developing the parental skills could also be helpful by participating in community action programs. Therefore, referring the mother of the child to one of the community programs could be an effective alternative. Cognition development example The cognition development between the age group of three to five is explained by the Piagets theory. This theory is further divided into sensorimotor, preoperational, concrete operational and formal operations (Case, 2013). Among these the most important stages are the sensorimotor and pre-operational stages as they act as a platform for processing language and individual development. Development of concrete operations is based on sensory memory that relates the way the adults talks with each other either through phones or in persons. The development stages of cognition are associated with different changes in biology and psychology (Nisbett et al., 2012). The normal cognition development will increase based on the processing thoughts in the age group of three to five years. Thus, based on this, the child should be involved in an environment with competitive group that supports the optimal child growth (Hart, 2013). Social development example The Eriksons theory explains clearly the social development in a child. Both the social and psychosocial factors help to increase the social development of the child through eight stages (Newman Newman, 2017). The first stage involves the stages of making queries for which they are usually dependent on their mother. In between the age of 2-7 the child develop the urge to learn. For example, it can be included the developing skills in clothing themselves and toilet training which was not properly developed in the child. This impairment could be due to reduced interactions with the parents and the peers. With this context, Vygotskys theory explaining the cognitive development could be considered for the social development that preceded the community interactions of the child (Forrester, 2013). Factors influencing the cognitive social development Evidential studies have reported that both the health and the genetic constitution affect the cognitive social development. Other factors include the physical development and health. The cognition can be impaired with the advent of the stress. Reduced health conditions of the child influence the childs power of thinking, interacting, learning and reasoning that is essential in the cognitive social development (Tzuriel, 2013). Relevant factors understanding to nurses and midwives By employing the Piaget theory, the nurses and the midwives would be able to guide the parents in their child overall development. The nurses should directly interact with the parents and help them to understand the major reason of depression leading to impaired learning in the child (Hockenberry, Wilson Rodgers, 2016). Conclusion Thus from the above discussion it can be concluded that the nurses and the midwives play a vital role in the overall development of the child. By implementing different theories of development such as Eriksons theory for social development and the Piagets theory of cognition development the nurses could assist effectively in developing the skills by providing a perfect environment to the child. These theories also assist them to provide the parents the exact guidelines to help their child in growing and developing. Thus, the nurses exert a perfect role in identifying the critical problems and provide the appropriate solutions to overcome the speech difficulties that hamper communication and helps in toilet training as identified in the current case study.

Ricky Schiano 9/9/14 Mrs. C. Kenny Honors Biology Climate Change Disrupts North America Bird Species FELICITY BARRINGER On Monday September 8 th , four students from the National Audubon Society discovered that climate change in North America could eventually drive certain species of birds to extinction. The students documented that around the year 2050 , 21.4% of bird sp ecies will lose more than half of their current population, and by 2080 an additional 32% of birds will be in the same situation. A changing climate may not seem like much of a problem, why can't the birds just migrate? Well many birds will, but then there will be some types that will not be able to due to the environment that was necessary to their survival. Birds like the yellow-billed magpie in rely on the scrub oak habitat in California. While the birds can fly away, the trees cannot, which holds them back from migration. This article is associated with out course because it has to do with ecosystems and organisms. Since the birds' ecosystem is changing, they will either have to move and repopulate, or stay and eventually die out.

Biology experiment essays

Biology experiment essays To investigate the factors affecting the rate of growth of mustard seeds. The key factors that will affect the germination of the mustard seeds: Temperature: as many plants germinate more rapidly in the warm. Water: as water normally controls germination. Oxygen: as seeds rapidly take in oxygen during germination. Light: as some plants need light to germinate. Dark: as most plants germinate in the dark. Soil composition: the richer in nutrient the soil is the better the seeds. Temperature: helps the plants to grow. Sunlight: gives the plant energy to grow and energy for photosynthesis. Moisture level: water is needed for growth and is absorbed and circulated Soil composition: depending on how rich in nutrients the soil is will help the Space: is needed for the plant to survive. Nutrients: help the plant to grow. Carbon dioxide: is essential during photosynthesis. In my experiment I am going to test how the mustard seeds grow in different soils and materials. 1) I predict that from my experiment the mustard seeds in the compost will grow the fastest and strongest because compost is a fertiliser and is rich in minerals and nutrients and this will make the seeds grow faster and stronger. 2) I also predict that the seeds in the cotton wool will grow the slowest as there are no nutrients in the cotton wool and because it will soak up the water. My experiment will show how Mustard seeds grow in different soils and materials. I think the seeds that will grow the strongest will be the ones that are planted in the compost. Compost is an Organic material decomposed by bacteria under controlled conditions to make a nutrient-rich natural fertilizer for use in gardening or farming. Compost is a fertilizer and all fertilisers contain Nitrogen for the growth of the leaves and stem, Phosphorus f...

Bio-Terrorism preparedness and response Module 3 case MHE 507 Essay

Bio-Terrorism preparedness and response Module 3 case MHE 507 - Essay Example However the operation is plagued by the lack of qualified and motivated staff members. This paper will seek to study and analyze the LRN. The Laboratory Response Network was created by the Centers for Disease Control and Prevention (CDC) as a means of responding to biological terrorism. The CDC established the organization with its partners, the Federal Bureau of Investigation and Association of Public Health Laboratories (McGovern, 311). The overall aim was to create an efficient mechanism that would upgrade the American public health infrastructure to respond to bioterrorism. The LRN uses a coordinated effort by government, military, health, and private laboratories to fight against possible bioterrorist threats. It helps to enhance the ability of the country to respond to biological and chemical terrorism. The Laboratory Response Network operates using a multi-tier organizational structure. Each level helps to create a multilayered security mechanism against potential bioterrorist acts. Sentinel laboratories are the first line of defense since they are concerned with identifying and assessing bioterrorism threat agents. They have the responsibility of treating samples in a safe manner (Roffey & Tegnell, 450). Reference laboratories typically have advanced equipment that is used to test and monitor the presence of specific biological threat agents. Finally national laboratories are present in military and government facilities for the purpose of identifying specialized biological agents (Treadwell & Koo, 92). The LRN represents a unique effort to fight bioterrorism because it integrates state, federal, military, veterinary, and international laboratories. Adequate funding has supplemented the efforts by providing the necessary equipment, instruments, and supplies to the network of laboratories. However a major shortcoming is the lack of qualified and talented staff (Inglesby, 1735). This was because qualified scientists and researchers

The most common disease due to COPD is chronic bronchitis, and women who are continuously exposed to the indoor smoke are the prime victims (World Health Organization, 2011). Apart from smoking, lung cancer can even be caused due to exposure to coal fires. The simple stoves used for cooking may even cause such diseases. Each year, the number of deaths due to lung cancer is one million and 1.5% of these deaths are caused by indoor air pollution (World Health Organization, 2011). In particular, children are more vulnerable to the effects of air pollutants because they are in their developmental stage and are physically different from adults. The lungs and airways of children are not matured and thus are more prone to the adverse effects of pollution. The lungs, in its developing stage, bear a large surface area that creates the easy absorption of pollutants. The breathing speed of the children is faster than adults and thus through inhaling, it absorbs a greater amount of contaminants in comparison to that of adults (Children’s Environmental Health Project, 2000). Researches show that children who reside in economically-disadvantaged areas that have high density of traffic may be prone to asthma exacerbation from exposure to air pollution (California Environmental Protection Agency, 2009). The exposure of the community to the impacts of air pollutants can be reduced by the below mentioned initiatives. The nurse who has been appointed for implementing the plan has to take the following initiatives to save adults and children from the exposure: One final advice that the nurse can provide is that of planting trees

Catcher in the Rye Comparison to Author Essay Example | Topics and Well Written Essays - 500 words

Catcher in the Rye Comparison to Author - Essay Example As Bloom (p.18) comments, â€Å"in addition to creating a maelstrom of controversy in its critical reception†, the novel clearly tell us about Salinger’s creativity, nature, and achievement. To illustrate, as a student, Salinger was considered poor in academics and he was criticized as the most worthless English student by one of his professors. He had to change a number of schools and had an unhealthy relationship with parents. In his novel, Salinger gave an identical image to Holden Caulfield. Holden also experiences such failures in his academics; fails to prove him better student and he was also sent away from parents for his studies. However, as Graham describes Holden, he was â€Å"expelled from his school, Pency Prep, just before the Christmas holidays for flunking everything else except English† (2007, p. IX).Salinger tried to explain much of his personal feelings and perceptions through Holden Caulfield in the Catcher in the Rye. â€Å"What I was really hanging around for, I was trying to feel some kind of a good-by. I mean I’ve left schools and places I didn’t even know I was leaving them. I hate that. I don’t care if it’s a sad good-by or a bad good-by, but when I leave a place I like to know I’m leaving it. If you don’t, you will feel even worse† (Salinger, 2007, chapter 1).

Transactionalism Analysis of Political Processes

Transactionalism Analysis of Political Processes Political Swat Barth Assess Barths Theory of Transactionalism In this book, such a paradigm of political experience not only tells us something important about the traditional political situation in Swat, it is also the basis of a trenchant criticism of views prevailing at the time when Barth wroteIt reveals that a quest for personal advantage could flourish in a traditional setting.† (Meeker 1980 : 684) It is important to distinguish, when discussing Political Leadership among Swat Pathans (1959), between its effectiveness as an ethnographic account, and its role as a work of theory. Barth’s later works were written when he had further developed his method with the support of the ‘Bergen school’, which included other Scandinavian ethnologists and continental authors such as Robert Paine. F. G. Bailey, in 1960, affirmed in his review for Man (p. 188), that â€Å"Barth’s book is a monograph and not a work of theory†. However, Barth’s 1959 article Segmentary Opposition and the Theory of Games: A Study of Pathan Organisation forms a â€Å"case study of unilineal descent and political organisation among Yusufzai Pathans [which] exemplifies a pattern, not previously described in the literature, of deriving corporate political groups from a ramifying unilineal descent charter.† (p. 19) Barth’s transactionalism, as a form of methodological individualism, developed in a general movement away from the dominant Durkheimian models of Radcliffe-Brown and Fortes. In a return to more Malinowskian traditions, authors including Bailey, Barth and Paine explored the ways in which cultural actors manipulate social rules so as to maximise their own profit. In addition, there was a growing need for anthropologists to account for change in societies which were increasingly exposed to a strongly Western, global political social model, rather than remaining static, as some theories would have had them. In his 1959 ethnography, Barth shows that the strategic choices of individuals significantly determine the political hierarchy, the latter which recognises the contractual right of individuals and thus demands that leaders consistently prove their status-worthiness. â€Å"In this respect the political life of Swat resembles that of Western societies† (Barth 1959a : 2). In moving away from the structural functionalist model, Barth took a decisive step in his proposition that the bases of the society were united by a solidarity based on â€Å"individual strategic choices†, rather than by the mechanical solidarity elaborated by Evans-Pritchard and Fortes in Africa. The authority systemis built up and maintained through the exercise of a continual series of individual choices. (Barth 1959a : 2) Criticism It is a saddening, but no doubt common, experience to see one’s analyses made banal and one’s points of view reduced to simple stereotypes. It is perhaps even more distressing to be attributed a web of trivial and fundamental errors and omissions which one has not committed. (Barth, correspondence in Dupree 1977 : 516) While much praised, Barth has had his fair share of able critics. In 1972, Talal Asad delivered a class-oriented polemic of Barth’s Pathans, insisting that the landlords exploited their tenants consistently, and that the author suffered from the â€Å"illusion of consent† in attributing free contractuality to their exchanges. Four years later, Akbar S. Ahmed wrote Millennium and Charisma among Pathans, arguing that Barth suffered from a â€Å"khan’s-eye view†, again proclaiming that the reality of Swat society involved far less ‘free choice’ than Barth would have us believe, people’s lives instead being shaped strongly by â€Å"a matrix of interacting and largely fixed social patterns† (cited in Dupree 1977 : 514). As did Asad, Dupree praises Barth as an â€Å"indefatigable fieldworker and imaginative theorist† (1977: 514); but Ahmed, he points out, was well qualified to document Barth’s ‘Norwegian entrepreneur bias’, not least since his wife is the grand daughter of the late Wali of Swat. â€Å"What Barth observes from the outside, Ahmed explores from the inside† (Charpenter, C. J. correspondence in ibid: 516). Louis Dupree’s 1976 article was republished in Current Anthropology in 1977, appended by correspondences from Barth and others interested in the debate. They address the issues raised by Dupree, especially that â€Å"there is a great distance between Barth’s model and the Swati ethnography as he (Ahmed) saw it in 1974† (Pettigrew J., correspondence in Dupree 1977). Pettigrew goes on to make an engaging point, to counter this, that â€Å"the issue is instead whether the models we use yield adequate information about societal processes† (ibid.). Somewhat later, in a review of Barth’s Selected Essays (1981), Ian Prattis is keen to point out Barth’s inability adequately to account for social change, and is of the belief that Barth is â€Å"opposed to grand conceptual schemes in general and to the direction taken by 1950s social anthropology in particular† (Prattis 1983: 103). Barthing Up the Wrong Tree shows that â€Å"Barth missed out crucial variables (power, intrinsic value) and claimed too much for the power of transactions to integrate social systems† (ibid. : 108). However, Prattis was concerned with the author’s output of two decades, while I am interested more specifically with his initial formulation of transactionalism, especially as exemplified in Political Leadership among Swat Pathans of 1959.

Ideology and Reality in the Movie, The Matrix Essay -- Movie Film Essa

Ideology and Reality in the Movie, The Matrix The matrix, as presented in the eponymous film, operates as an Althusserian Ideological State Apparatus (ISA). The Matrix1 presents a world in which "the state [as] a 'machine' of repression" is made literal where robots rule the land (Althusser 68). It is true that they rule by force (sentinels and agents) and these constitute the Repressive State Apparatus, but their primary force of subjugation is the matrix, their ISA. The film traces the path of one man, Neo, in his painful progress from the ideology of the matrix to the "real world," or the ideology of the "real."2 The matrix, unlike the ideology of the "real," is explicitly defined along Althusserian lines as an ISA. Althusser identifies ISAs as "a certain number of realities which present themselves to the immediate observer" (Althusser 73). Just as the "machine" of the state is taken literally, ideology as "reality" is taken literally. Any discussion of the ISA must include both a brief discussion of the State and Althusser's use of the term "ideology." For him, the State "has no meaning except as a function of State power" and as such, "the State is the repressive State apparatus" (71-72). The State Apparatus (SA) is in turn comprised of the Repressive State Apparatus and the Ideological State Apparatus. The RSA will be discussed in further detail later, but to understand how the matrix serves as an ISA, a brief discussion of ideology is called for. Althusser defines the ISA as those private institutions that operate by ideology instead of physical repression. Ideology, as a term, has two aspects for Althusser. The first is that "ideology represents the imaginary relationship of individuals to their ... ... amount of time that passed between The Matrix and The Matrix Reloaded. 2 To be concrete about the difference between the matrix and the "real world," I will refer to one as the matrix and the other as the ideology of the "real." The quotes are necessary as the ideology of the "real" is still a fictional ideology. Furthermore, it must be remembered that Althusser saw ideology as inescapable and a necessary feature of society ("there is no practice except by and in an ideology") (Althusser 93). Therefore, referring to the world outside of the matrix as the real world is insufficient and inaccurate. The ideology of the "real" (as Morpheus says, "welcome to the real") serves to enforce the notion of Neo not as rejecting ideology in favor of reality, but rather moving from the ideology of the machines (the matrix) to that of Morpheus (the ideology of the "real").

The test statistic constructed by the ratio of the estimated coefficient to its standard error is normally distributed because we are using the normal distribution to model the expected value of the dependent variable c. The partial effects of an explanatory variable are quantitatively close to zero when the standard error of the coefficient on this variable is very large. d. All of the above 8. You have data on a sample of 95 managers working in large firms in Australia. You estimate a logit model of Y= 1 if earning >$500,000 per annum using as explanatory variables: F=1 if the manager is female (0 otherwise); PHD=1 if the manager has a PHD (0 otherwise); an interaction variable FPHD=F*PHD; TEN=tenure with the firm measured in years (a continuous variable). You find the following estimates: Indexi = 0.053 – 0.095 Fi + 0.020 PHDi + 0.007 FPHDi + 0.0015 TENi (0.002) (0.011) (0.009) (0.003) (0.0005) where the standard errors are denoted in parenthesis. You want to test H0: tenure has no effect on the probability of earning >$500,000 per annum versus H1: tenure has a positive effect on the probability of earning >$500,000 per annum. You will use a 5% level of significance to conduct this test. You get an asymptotic t-stat equal to 3.0. Using the tables provided at the end of the exam, choose one of the following as an appropriate critical value to conduct this test: a. 1.662 b. 1.645 c. 1.987 d. 1.960 e. 5.0239 9.

Under the null, the Wald test statistic is asymptotically chi-squared distributed with a. 1 degree of freedom b. 90 degrees of freedom c. 93 degrees of freedom d. 2 degrees of freedom e. 3 degrees of freedom PART A. Multiple Choice 1. C 2. D 3. B 4. C 5. B 6. D 7. A 8. B 9. C 10. D SOLUTIONS Part B. Problem (Total 30 marks) Equity of access is a primary goal of many health systems. Determining whether Australia’s system (Medicare) meets this goal is an important research question. Consider the case of access to general practitioners (GPs). The probit results presented below in Table 4 are part of an analysis aimed at answering whether there is equitable access to GP services where access is defined on the basis of health needs rather than ability to pay. The data consists of a sample of 3207 single females who were surveyed throughout Australia in 1995. The â€Å"dependent variable† for the study was VISIT, an indicator variable that was equal to one if the women had visited a GP in the last two weeks and zero otherwise. The sample has been divided into two subsets depending on whether the women are less than 40 years old (the â€Å"young† sub-sample) or whether they are greater than 40 years old (the â€Å"old† subsample). Table 4 presents estimation results (variable defini tions follow the table). Young Old Table 4: Probit estimates for visit to GP* Variable Intercept -0.7910 (0.1602) -1.1570 (0.2495) AGE -0.0060 (0.0064) 0.0055 (0.0033) HEALTH 0.3930 (0.0687) 0.6131 (0.0746) KIDS 0.1651 (0.0881) -0.1479 (0.1159) INCOME 0.0003 (0.0032) -0.0052 (0.0037) TERTDUM 0.0120 (0.1042) 0.0844 (0.1509) TRADEDUM 0.1842 (0.0884) 0.2399 (0.1013) DIPDUM 0.0077 (0.1281) 0.0478 (0.1422) PHI 0.0258 (0.0783) 0.1781 (0.0768) Observations 1717 1490 Log-likelihood -935.52 -892.24 PART B. i. (8 marks) Discuss the effects of PHI on the probability of visiting a GP and compare these effects for the two subsamples of young and old women. Repeat the exercise for the KIDS variable. Do you think that these variables are likely to violate the zero conditional mean assumption? Discuss PHI: In both subsamples, the estimated coefficient on PHI is positive; ceteris paribus the probability of visiting a GP is higher for those with PHI than without. The size of coefficients may be discussed using the rule of thumb but these must not be confused with partial effects. The effect is statistically significant among the old while the opposite is true for the young. In the young subsample, the coefficient is insignificant at any conventional level (t statistic for testing irrelevance of PHI against the 2-sided alternative is 0.3295 < 1.645) whereas in the old subsample it is significantly different from zero at the 5% significance level (t statistic = 2.319 > 1.96). The sign is as expected since PHI makes it cheaper to use GP services and women who expect to visit GPs more often are more likely to purchase PHI. The latter implies that ZCM may be violated due to a selection effect. KIDS: In the young subsample, the coefficient on KIDS is positive and statistically different from zero at the 10% level (t statistic = 1.874 > 1.645); the probability of GP visit is higher for those with dependent children. In the old subsample, the sign of the coefficient indicates that the effect is negative but the coefficient is statistically insignificant from zero at conventional levels (t stat = 1.276 < 1.645). A priori, the expected sign is ambiguous; women may visit GPs for children’s medical care as well as their own (positive) but at the same time they may become busier due to child rearing (negative). For the old sample, KIDS may be older and hence mothers no longer visit GPs for the children’s health. Other reasonable explanations are acceptable. You can argue both ways on the ZCM assumption: for example, you can argue that fertility decisions are exogenous to GP visits. You could also argue that there is an omitted variable bias (KIDS is picking up some unobserved component – e.g. better health measurement – than what is being captured by the existing explanatory variables). Also if the true underlying relationship depends on the number of resident dependent chi ldren, KIDS is top-coded at 1, causing the ZCM assumption to fail due to a measurement error correlated with this variable. Additional material: You could also earn marks (lost elsewhere in the question) by discussing the size of the effects. For example, the effect among the young seems non-trivial in the sense that the coefficient’s magnitude is slightly over 40% of that of the coefficient on the poor health indicator (HEALTH) while for the old, the variable seems far less economically relevant relative to HEALTH. ii. (5 marks) If there is equity of access then variables related to income, education and private health insurance should not affect visits to GPs. When the models are re-estimated without these variables (i.e. with only AGE, HEALTH and KIDS included) the log-likelihood values are – 937.92 for the young sub-sample and –898.63 for the old. Using these results evaluate the null hypothesis of equity of access. Statement of the hypotheses: Calculated statistics: LR test statistics: LLRYOUNG = 2(-935.52+937.92) = 4.8; LLROLD = 2(-892.24+898.63) = 12.78. Distributions of the test statistics and critical values: They are asymptotically chi-squared distributed with 5 degrees of freedom under the null. The appropriate 10% and 5% critical values are 9.2364 and 11.0705 respectively. Decision rules and conclusions: Since LLRYOUNG < 9.2364, we fail to reject the null at 10% level in the young subsample; there is not enough evidence to conclude that income, education and PHI variables affect young women’s GP visits. Since LLROLD > 11.0705, we reject the null at the 5% significance level in the old subsample and conclude that there is some evidence against equity of access among the old women. iii. (4 marks) Consider two types of women: type #1 where AGE = 20, HEALTH = 1, INCOME = 20 and all other variables = 0; type #2 is identical except that AGE = 60. Write down the equation(s) you would use to compare the probability of visiting a GP for these two types of women. Using the probit results can you determine which of these two types of women are more likely to have visited a GP in the last two weeks? If your answer is yes then make the comparison, if your answer is no then explain what information you would need to make the comparison. One possible answer is to use the index and argue that the ranking by the probabilities will be the same as that provided by the index: Index for type #1 = -.791 + -.006*20 +.3930 + 0.0003*20 = -.5120 -.51 < Index for type #2 = -1.1570 + .0055*60 +.6131 – 0.0052*20 = -.3179 -0.32 Since the standard normal CDF increases in the probit index, type #2 woman is more likely to visit GPs than type #1 woman. Another possible answer is to write down the normal CDF for the two types and argue that the equation for type 2 will be greater than type 1. Additional material: You could also earn marks (lost elsewhere in the question) by calculating the difference in the probabilities using the table on p.10 of the exam paper; i.e. the difference in the predicted probabilities can be evaluated as (.5-.1255)-(0.5-.1950) = 0.0695 .07 higher for type 2. iv. (6 marks) In determining the sample to be used for estimation, any individual who did not report their income or reported zero income was deleted from the analysis. Do you see any real or potential problems with this modelling decision? Can you provide an alternative method to deal with this problem? Likely problems (one of the following or another sensible problem): -The potential selection bias which arises when the decision to report zero income or refuse reporting any is correlated with the decision to use GP services. For instant, top income groups may be more jealous of their income information and at the same time more likely to be health conscious and visit GPs in consequence; excluding the said individuals would affect all coefficient estimates as the model would have to predict a lower probability of GP visit on average. -The decrease in the sample size and the resulting increase in standard errors. The incomplete cases may still provide useful information on the effects of other variables on GP visits and the researcher has discarded this information. Alternative solutions (one of the following or another sensible solution): – Use other information to impute the missing information – Use dummy variables for missing income. – More sophisticated imputation methods – Estimate a selection model (this is covered in more detail later in the class but you may know about it from reading or elsewhere) v. (7 marks) Explain how you would construct and use a hit and miss table to compare the performance of the models for the two subsamples of women (young and old). (You do not have to actually construct a table.) Step 1. Calculate a predicted probability for each person in the relevant subsample. Step 2. Obtain a predicted binary outcome for each person using a classification rule: if person i’s predicted probability exceeds c, the predicted outcome is 1 and otherwise 0. It is ok if you use 0.5 or the sample mean. Step 3. For each subsample, tabulate frequencies of predicted and actual binary outcomes in the following form: Predicted 01 Observed 0 A B 1 B’ A’ where: A (A’) = the total number of women whose predicted and observed outcomes are 0 (1) B (B’) = the total number of women whose observed outcome is 0 (1) but the predicted outcome is 1 (0). Step 4. Now, compare the relative frequencies of correct predictions for each subsamples; i.e., compare (A+A’) / (A+B+A’+B’) across the subsamples. This tells us how well one model performs relative to another in terms of predicting the observed outcomes. It is ok to describe the comparisons of the predicted 0’s separately from the predicted 1’s (ie the comparisons of A / (A+B) and A’ / (A’+B’) across subsamples) but this is not needed for full marks.

EVELINE essays

EVELINE essays James Joyce's Eveline was originally published in his short story collection called Dubliners. As the name suggests the story revolves around a young woman named Eveline who is torn between her past and her potential future life not knowing which to choose. The themes of sexuality and gender dominate the story as Eveline is shown trapped in a patriarchic society and the only hope for escape is marriage. This sheds light on the general thinking of men and women in modernist society. Women were usually mistreated or accorded less respect than they deserved and this is what happens to Eveline. Every young woman then grew up believing that marriage would save her from all her troubles. James Joyce explores this issue carefully to illustrate the flaws in such thinking and the reasons why most women consider marriage an answer to all their troubles. The problem with Eveline is that on the one hand, she wants to escape her present life that was defined by her father's violent temper and her monotonous job at the Stores, on the other she also lacks courage to change her life primarily because of fear. The decision of Eveline to not leave her home and familiar objects can be both praised and condemned because it is based on two things, rational thinking and fear. The fact that Eveline "prayed to God to direct her, to show her what was her duty." (Joyce 331) shows that women are conditioned to pout duty before love and a better life. They are made to believe that they must make sacrifices for the sake of others and must not think about their owjn wishes and desires as that is considered selfish. After carefully weighing the pros and cons of her decision, Eveline realizes that her chief reason for marrying Frank was a desire to escape her present circumstances and thus she decides not to run away at the very last minute. On the other hand, her decision is also motivated by fear of her father an...

Free Essays on Safety At Play Free Essays on Safety At Play Childhood is the period of life that enables children to become competent and develop into confident adults. The role of an adult will influence the child significantly and during childhood, a child relies on the adult to care, protect and support whilst they learn and gain knowledge of the world. Part of the role and adult plays in a young child’s life is that of looking out for risks that a child may not anticipate. This is a natural instinct but can be taken to extremes by restricting a child from certain things. Restricting activities or disallowing a child from doing something because of fears about what might happen, blocks the development of a child intellectually which in turn causes social, emotional and physical deteriation. An adult needs to understand that it is impossible to shield a child from all risk whether it is part of their development, physically, emotionally or intellectually. All children need and want to take risks. A child will learn through risk and the ‘’learning has to be grounded in their own personal, social and emotional development.’’ (Jennie Lindon 2003). The lessons they need to learn focuses on confidence and ability. They need to feel confident enough to deal with mistakes and to take risks with the confidence that it is all right not to know something. Confidence is also needed to learn new words in order to express opinions or doubts in situations. Thus developing language and communication skills.

Enzyme Linked Assays Essay Example | Topics and Well Written Essays - 1250 words

Enzyme Linked Assays - Essay Example hydrogen donors in equation 2 and 3 is quite low, as a result AH2 can be a variety of compounds, and many different bindings or linkings are possible. In this way antibodies are conjugated to enzymes in order to amplify the signal via the catalytic properties of the enzymes. HRP conjugates are ideally used for ELISA or enzyme- linked immunosorbent assays. HRP has a fast catalytic rate and can generate more products in shorter incubation time, allowing for greater sensitivity. HRP-labeled antihuman IgG can be used to bind to target antigen in an assay system to localize even trace amounts of biomolecules. This biomolecules produce dityrosin bonds by reaction with HRP to produce (Adopted from Rob, P.M. et al. 2002). When used for an assay this will give rise to a reaction like Different types of linked assays and their properties: There are mainly two types of ELISA assays. 1. Sandwich. 2. Competitive. Sandwich: This is also known as two-antibody sandwich ELISA. This is used for determination of antigen concentration in unknown samples. With a purified antigen standard, it can determine absolute amount of antigen in a sample. This requires two antibodies, capture and detection, that bind to epitopes that do not overlap. Two monoclonal antibodies that recognize discrete sites on the antigen or two polyclonal affinity purified antibodies are used. The capture antibody is purified and bound to the solid phase. Antigen is added, and antigen-antibody binding occurs. This creates a sandwich. Quantification of the assay is then made by measuring the amount of labeled second antibody bound to the matrix by the use of a colourimetric substrate (Please see the picture). Competitive: Nonpurified primary antibodies may be... Kay,E., Leland, M. S., and Lew, J. Y., (1967). Peroxidase Isozymes from Horseradish Roots, Ii.

Why Information Assurance (IA) is Important to our Organization Essay

Why Information Assurance (IA) is Important to our Organization - Essay Example Information assurance provides the basis that a network system should meet the stipulated security expectations. A network system that meets these goals is less vulnerable to unauthorized penetration and attacks. In practical, every system is vulnerable to unauthorized penetration and attacks unless it is switched off or not connected to network. Information assurance is closely related to information security and the terms are sometimes used interchangeably. Information assurance’s broader connotation also includes reliability and emphasizes strategic risk management over tools and tactics [Wikipedia]. According to Tulloch (2003), Information assurance is the process of protecting and defending information systems and infrastructures against attack. Here assurance means confidence that the security features of a product or system fulfill their stated aims. Information assurance provides policies and procedures for developing, testing, and implementing information products in a secure fashion. These policy contains several do’s and not do’s that every staff of the organization have to follow. In addition these policies are constantly monitored by IA staff. Information assurance in general focuses on five elements of information security and they are authentication, availability, confidentiality, integrity and non-repudiation. Confidentiality, integrity, and availability are often viewed as core elements of information security and are generally referred to as the â€Å"CIA triad.† An increasingly popular approach for ensuring information assurance is the Common Criteria & Methodology for Information Technology Security Evaluation, an international effort to standardize criteria for evaluating the security of information systems outlined in the ISO 15408 standard. [Tulloch 2003, p.143] Information being the driving tool of every business and network connectivity on ground to boost productivity means that more people

Risk Management Essay Example | Topics and Well Written Essays - 1000 words

Risk Management - Essay Example This paper will describe a risk context that may be faced by the top level executive of a bank while marketing it financial services. Risk contexts A bank executive normally faces different types of risks once the bank deals with ranges of transactions and uses a large amount of leverage every day. When a bank’s financial position becomes weak, naturally its depositors may withdraw their savings. Under such a difficult situation, the bank cannot sell debt securities in financial markets; and this condition would worsen the bank’s financial state. For instance, the major cause of 2007-2009 credit crisis can be attributed to the fear of bank failure. According to Pyle (2007), although a bank executive may share many of the same risks of other organizations, the major risks that really trouble an executive are liquidity risk, credit default risks, interest rate risks, and trading risks. Risk Identification and Analysis 1. Liquidity risk In case of a bank, the term liquidit y indicates its ability to pay bills and other payables, to repay money to a depositor, and to lend money to a borrower as part of bank’s credit policy. Hence, liquidity is the basic tool that is used to assess the financial viability of a bank. A bank executive faces great troubles while dealing with liquidity management because demands for funds are often unpredictable. Other off-balance sheet risks including loan commitments, letters of credit, and derivatives also constitute liquidity risks. A loan commitment indicates a line of credit that a bank issues on demand. Letters of credit are credit securities by which the bank guarantees that an importer will pay the exporter for imports or a commercial paper of bonds issuer will repay the principal. Finally, derivates are also an off balance sheet risk, which played a crucial role in the collapse of American International Group (AIG). 2. Credit Default Risks Credit default risk occurs when a borrower fails to repay the loan a mount. In general practice, loans are written off after a period of 90 days of nonpayment. Law demands banks to maintain a loan loss reserves account to cover the losses arising from unpaid loans. A bank executive or manager has the responsibility to ensure that the borrower has submitted collateral securities that are adequate to cover his loan amount. In addition, the bank executive has the primary responsibility to recover the loan amount from the borrower. Therefore, bank executives would be liable to answer the board of directors when a loan goes unpaid. 3. Interest Rate Risks Banks usually pay lower interests on its liabilities such as deposits and borrowings and charge higher interests on their assets such as loans and securities. Hence, it is obvious that difference in these interest rates is the main source of profit for any bank. However, a bank’s terms of liabilities are usually different from its terms of assets. In other words, interest rate paid on liabilities i s highly subjected to short term rate fluctuations while interest rate earned on assets is fixed. Sometimes, the interest rate variation may cause the bank to pay more for its liabilities and thus reducing the bank’s profit rates. Under such circumstances, a bank executive faces interest rate risk. Since the interest rate fluctuations are unpredictable, often a bank executive f

Early Humans Essay Example for Free

Early Humans Essay What animals did the early humans hunt for food? Early humans found meat from animals that were back in the day, the meat was not so common because before they had animals they had other types of food like for example, fruits from trees, nuts and sometimes even honey and the y also got berries form the burry bushes like raspberries, strawberries, blueberries and so on, but the animal that they always use to eat in the ancient times was the buffalo which was one of the most common animals in there specific villages and mostly when they would get the animals they would open them up with sharp things and then they would eat the meat and by the time they figured out fire they used fire to cook the food like we do know. How the early Human nut and got their food? Well the simple answer is that they used weapon to hunt the animals but we always thought that the early humans are stupid but the truth is that they are actually very smart because of the weapons they used for hunting and another thing they did to hunt food was that back in the early days there was a group of people called hunter gatherers and what hunter gatherers are is that basically a group of people for example from villages (mostly man) would go out to hunt for food mostly everyday and then when any of them would get food they will bring it to the group of people that they are and then the would most probably share the food with the people. And mostly the weapons would be made out of stones and wood. Also an example of the weapons they used wear spears and bows made out wood and stones. The most common food eaten nowadyaus are seeds. Also very populare is vegetables and fruits.

Dialectoc Composition In Purgatorio V :: Purgatorio V Poem Poetic Essays

Dialectoc Composition In Purgatorio V In this canto there appear to be none of those cruces on which contemporary criticism often fastens as basic for the understanding of the poem's deeper meaning. It nevertheless contains some of the most vivid episodes of the journey, especially in its second part, involving the stories of three memorable characters. As is characteristic of the whole cantica, and is especially evident in the first cantos, we find that the three souls we meet here are, by the very definition of their realm, in a liminal state between two forms of existence, the earthly and the celestial. They are gradually shedding the prejudices and passions that had made them cling to the illusory goods of their earthly existence, and getting ready, through their painful purgation, for the permanent bliss to come. We shall see how, by the very progression that distinguishes them among themselves, the three main characters are increasingly detached from the worldly values and increasingly ready for the final step. In one of the more recent  «lecturae » Giambattista Salinari (1969, 311 and 313f) finds that this canto is marked by a high degree of lyricism, considering the progression of the three generic ingredients of the whole poem, namely the descriptive (or epic), the dramatic, and the lyric. He also stresses here the particularly conspicuous presence of what he calls the three types of  «contrappunto » in which Dante excels, namely the  «horizontal » (when contrasting episodes are juxtaposed for the sake of variation and emphasis), the  «vertical » (when over several characters the same situation or theme is developed through rising tonalities), and finally the  «stylistic » (when in the same episode the epic or narrative element is expressed through elegiac description, the dramatic through dialogue, and the lyric through monologue). This is, in short exposition, an interesting analytic point that concerns a striking yet little noticed feature of Dante's method o f composition, and which this writer has attempted to define and analyze under the term of  «dialectic composition ». The structure of Purgatorio V leans, as it were, backward and forward, tying in with the conclusion of the episode of the lazy in the preceding canto and then concluding the episode of the violently slain, who properly occupy this canto, in the following canto, when the same group continues to crowd around Dante in order to secure prayers on their behalf from the living.

Social Responsibility in Akira Kurosawa’s Movie, Seven Samurai :: Movie Film Essays

Social Responsibility in Akira Kurosawa’s Movie, Seven Samurai It is truly a corrupt time when keepers of the peace must create unrest in order to survive. In sixteenth century Sengoku jidai Japan, it is survival of the fittest; a major part of this survival is what class one has been born into. Organized politics have been said to be a luxury of developed civilizations. Given that a poor farming village in sixteenth century Japan is hardly developed, the harsh rules of nature are ascribed to instead. Weakened by a continuing drought topped with unrelenting bandit raids, they must appeal to those who are stronger for help. However, in this land where the strong are successful, this will mean anyone who comes to the aid of these farmers will be stooping to work for their social inferiors. It is understood that violence has a starring role in samurai movies. In recent markets, a movie with as much blood as dialogue, though harshly criticized, will do decently in the box office. For the most part, Western cinema has been blamed as the cheapener of something that once was art. However, Akira Kurosawa’s Seven Samurai approaches mortal combat from a different perspective. The scavenging bandits kill indiscriminately, taking what they want and destroying the rest. The honorable samurai, on the other hand, use their sword sparingly. The movie’s first killing is given to Kambei, who draws his sword on a kidnapping robber only to save another life. Credit is due to Kurosawa who takes care not to make light of death. In a particularly haunting scene, a bandit lays impaled on a villagers spear. This portrayal of the impact taking a life can have is something often overlooked a genre that usually glorifies the act. Kurosawa’s greatest achievement with Samurai is his statement on social responsibility. Kambei and his team of samurai choose to help the villagers despite the lack of a reward or even glory. By helping those less fortunate to achieve a semblance of at least a productive way of life and exterminating those who are willing to exploit others for personal gain, a nation can be at peace and therefore prosperous.

Last Product Purchased Essay

Think for a moment about the last product you purchased. What was the product? What is the brand name of the product? How would you describe the customer for this product? What is the product’s closest brand competitor? Explain why you chose this brand rather than the competitor’s brand. How did the marketing for the product influence your purchase? The last product I purchased was my new car. It is a 2012 Chevrolet Malibu. The customer for this product would be a young adult to middle aged adult. The customer for this car wants a car that is smaller in size but one that also has plenty of room for at least 4 people. The closest brand to this car would be, in my opinion, the Pontiac G8. When I purchased my Malibu I went to test drive the G8. It was a 2011 and had only a few miles on it. It was traded in for a different car because the car was too small for the current owner. I loved the G8 and it was everything I wanted. It was only a couple thousand dollars less than the Malibu and the Malibu was brand new with only 20 miles on it. My husband is the one who really liked the Malibu and talked me into test driving it. Needless to say that is the car I choose. I chose this particular car because with the FREE extended warranty and the rebates on this car it turned out to be a cheaper car than the G8 but also a better car. Honestly the marketing on this car did not influence my opinion at all. I never thought about this specific car until at the dealership that day. When I purchased this car Chevrolet has awesome rebates and interest on their new vehicles. After my purchase I stared seeing, or paying attention, to the commercials on this car and I am positive I made the right decision. If I would have paid attention to the commercials on this car it would have been the car I chose anyway.

History of Kitchen Appliance Inventions

History of Kitchen Appliance Inventions By definition, the kitchen is a room used for food preparation that is typically equipped with a stove, a sink for cleaning food and dish-washing, and cabinets and refrigerators for storing food and equipment. Kitchens have been around for centuries, however, it was not until post-civil war period that the majority of kitchen appliances were invented. The reason was that most people no longer had servants and housewives working alone in the kitchen needed culinary help. The advent of ​electricity greatly advanced the technology of labor-saving kitchen appliances. History of Large Kitchen Appliances Dishwasher:  In 1850, Joel Houghton patented a wooden machine with a hand-turned wheel that splashed water on dishes, it was hardly a workable machine, but it was the first patent.Garbage Disposer:  Architect, inventor John W. Hammes built his wife the worlds first kitchen garbage disposer in 1927. After 10  years of design improvement, Hammes went into business selling his appliance to the public. His company was called the In-Sink-Erator Manufacturing Company.Ovens or Stoves:  The first historical record of a stove refers to a device built in 1490 in Alsace, France.Microwave Ovens: The microwave oven was invented by Percy L. Spencer.Refrigerator: Before mechanical refrigeration systems were introduced, people cooled their food with ice and snow, either found locally or brought down from the mountains. History of Small Kitchen Appliances Apple Parer: On February 14, 1803, the apple parer was patented by Moses Coates.Blender:  In 1922, Stephen Poplawski invented the blender.Cheese-Slicer:  The cheese-slicer is a Norwegian invention.Corkscrews:  Corkscrew inventors were inspired by a tool called the bulletscrew or gun worm, a device that extracted stuck bullets from rifles.Cuisinart  Food Processor:  Carl Sontheimer invented the Cuisinart food processor.Green Garbage Bags:  The familiar green plastic garbage bag (made from polyethylene) was invented by Harry Wasylyk in 1950.Electric Kettle:  Arthur Leslie Large invented the electric kettle in 1922. General Electric introduced the electric kettle with an automatic cut-out in 1930.Weber Kettle Grill:  George Stephen invented the original Weber Kettle Grill in 1951.Mason Jar:  John Mason patented the screw neck bottle or the Mason Jar on November 30, 1858.Electric Mixers:  The first patent that can claim to be for an electric mixer was issued on Novemb er 17, 1885, to Rufus M. Eastman. Lillian Moller Gilbreth (1878-1972), the mother of 12 children, also patented an electric food mixer (at a later date). Mixmaster:  Ivar Jepson invented Sunbeam Mixmaster, which he patented in 1928, and first mass-marketed in 1930.Paper Towels:  The Scott Paper Company was founded in Philadelphia by Irvin and Clarence Scott in 1879. Brothers Seymour and Irvin Scott ran a paper commission business for twelve years, but the poor economy in the 1870s forced them out of business. Irvin and his younger brother, Clarence, then decided to form their own company out of the remains of the first. Irvin reportedly borrowed $2,000 from his father-in-law and added it to the $300 the two brothers had to form the capital of Scott Paper Company. In 1907, Scott Paper introduced the Sani-Towels paper towel, the first paper towels. They were invented for use in Philadelphia classrooms to help prevent the spread of the common cold from child to child.Peelers:  The nineteenth-century created numerous kitchen use inventions: toasters, potato mashers, apple/potato peelers, food choppers, and sausage stuffers were all invented. Over 185 patents for coffee grinders and over 500 patents for apple/potato peelers were patented in the 1800s. Early peelers were made of iron and the patent number and other information were included in the casting. Peelers ranged from the familiar and simple round swiveling rod with a knife blade that peeled skin, to contraptions full of gears and wheels that could peel, core, slice, and section. There were separate peelers designed for different fruits and vegetables; there were even peelers that removed the kernels from ears of corn.

What Makes Aphid Reproduction So Efficient

What Makes Aphid Reproduction So Efficient Aphids thrive by the sheer force of their numbers. Their secret: Because just about every insect predator looks at them as an appetizer, their only chance of survival is to outnumber them. If aphids are good at one thing, its reproducing. Consider this fact from entomologist Stephen A. Marshall in his book Insects: Their Natural History and Diversity​: In optimal environmental conditions and lacking any predators, parasites, or disease, a single aphid could produce 600 billion descendants in one season. Just how do these tiny sap suckers multiply so prolifically? They can change the way they reproduce and how they develop as environmental conditions change. Aphids Can Reproduce Without Mating (No Males Needed!) Parthenogenesis, or asexual reproduction, is the first key to an aphids long family tree. With few exceptions, aphids in spring and summer are all females. The first wingless matriarchs hatch from eggs in early spring (from eggs laid late the prior year to overwinter), equipped to reproduce without the need for male mates. Within a few weeks, these females produce more females, and soon after that, the third generation arrives. And so on, and so on, and so on. The aphid population expands exponentially without a single male. Aphids Save Time by Giving Birth to Live Young The life cycle goes much quicker if you skip a step. Aphid mothers are viviparous, meaning they give birth to live young during the spring and summer, rather than laying eggs during these seasons. Their offspring reach reproductive maturity much sooner since they dont have to sit around waiting to hatch. Later in the season the females and males both develop.   Aphids Dont Develop Wings Unless They Need Them Most or all of an aphids life is spent feeding on a host plant. It doesn’t need to go very far, so walking suffices. Producing wings is a protein-intensive task, so aphids wisely conserve their resources and their energy and remain wingless. The aphids do quite well in their apterous state until food resources run low or the host plant gets so crowded with aphids that the group must disperse. Only then do they need to grow some wings. When the Going Gets Tough, the Aphids Get Going High populations, which occur quickly in light of the aphids prolific reproduction, lead to less than optimal conditions for survival. When there are too many aphids on a host plant, they begin competing with each other for food. Host plants covered in aphids are rapidly depleted of their sap, and the aphids must move on. Hormones trigger the production of winged aphids, which can then take flight and establish new populations.   Aphids Adapt Their Life Cycle to Environmental Conditions All would be for naught if the aphids in cold climates just froze to death at years end. As days become shorter and temperatures fall, aphids begin producing winged females and males. They find suitable mates, and the females lay eggs on perennial host plants. The eggs will carry on the family line, producing next years first batch of wingless females.

Globalization - Good or Bad Essay Example | Topics and Well Written Essays - 1000 words - 1

Globalization - Good or Bad - Essay Example In terms of International Trade, the author has described globalization as the platform that sets a level playground for both rich and poor countries. The author has also affirmed the less developed country can only improve their situation through the assistance of World Bank and the International Monetary Fund. I agree to a greater extent the assertions of the author except at some few issues which I total disagree. The World Bank and the International Monetary Fund have been described by the author as the pillars of global governance systems. The author overlooked the power of sovereignty of states, democracy, and the international justice system. The claim that developing countries can only improve their situation through these two global financial institutions is not accurate. Wallerstein (2004) pointed out that the World Bank and the International Monetary Fund is ‘training’ poor countries to depend on them. Developing countries have difficulties servicing the loans they receive from these organizations. They find themselves overburdened by the huge interest rates and end up borrowing again from other sources including internal sources. This creates a scenario similar to the one of digging a hole to bury another hole. The problem still remains. In this regard, I view the two institutions as contributing to the slow growth of developing economies and not as the sole path to their economic prosperity. Multinational companies in developing countries have been highlighted as better paying compared to the local firms and that foreign firms are not really oppressing their workers. Hurst (2008) claim that multinational companies are one of the social oppressions in less developed and poor countries. They offer jobs to locals at a higher wage than local firms, but this should not justify the poor, working conditions, job insecurity, or the prolonged hours of work often witnessed especially in the manufacturing industry. The author claims that if the w orkers were not happy with these companies then they would leave. Hurst (2008) explains that is huge labor force in developing countries and very few job opportunities which leaves many workers to ‘persevere’ where they are. The reason, therefore, why these workers continue working for the foreign firms is not because they are happy but rather because they have nowhere else to look for a livelihood. On the issue of foreign companies being nothing compared to the government, and not being able to raise an army or taxes, the author failed to put into perspective that, at times, some senior government officials usually have personal interests in these companies. Revesz (1997) stated that when it comes to crisis where multinational firms are being accused of various reasons, ‘the states cannot be trusted’ in the way the matter is handled. He observed that despite huge negative publicity and accusations from both the media and the public, the government remains silent and waits for the ‘tide to settle’. The international trading system has been implied by the author as unbiased against developing countries. This may be true as far as international trade laws and regulations are concerned. But, on the other hand, according to Wallerstein (2004), there is a more serious issue of trade imbalance whereby developed countries have an upper hand due to their economic strength advantage, superior
