Selective Dialkylation of a Doubly Linked Dicyclopentadiene Ligand and Research Paper

Selective Dialkylation of a Doubly Linked Dicyclopentadiene Ligand and the Ensuing Ruthenium Complexes - Research Paper Example The authors state the motivation behind such an approach as â€Å"While Ru3(CO)12 is an ideal starting material with regard to the cis to trans isomeric ratio formed around the doubly linked dicyclopentadienyl ligand, the CO ligand usually requires high heat or photolytic conditions and laborious chemicalsteps to remove it from the metal center. These chemical steps reduce the synthetic versatility of the resulting ruthenium complexes that contain a CO ligand† (Fier, et al., 2011). The paper concludes with a structure refinement of the obtained diruthenium complex which has the structural representation: Synthesis Route The reaction begins with the hydroxyl bromination of 4,4,8,8-tetramethyl-1,4,7,8-tetrahydro-s-indacene (1a; C2v symmetry) and 4,4,8,8-tetramethyl-1,4,5,8-tetrahydro-s-indacene (1b; C2h symmetry) by N-bromosuccinimide (NBS), NH4OAc and H2O/ Acetone. The dehydration of the resulting compound was done under anaerobic conditions in the presence of p-TsOH.H2O to yie ld the compounds 2 a,b. Reaction of 2a,b with MeMgBr in the presence of Ni-(dppf)Br2 (dppf = 1,1?-bis(diphenylphosphino)ferrocene) gave (C5H3Me)2(CMe2)2 (3a,b) in 31% yield. However, it was found that this compound 3 a,b did not react very well with RuCl3.3H20. Adding a bulkier alkyl group could lead to a specific 2,6 bonding making advantage of stearic repulsion with the methyl groups in the 4,8 position. Thus, the first reaction was modified to yield: Reaction of 4a,b with RuCl3 ·3H2O in MeOH (140  °C,15 min) gives a green-black heterogeneous mixture, with filtration of the mixture yielding a dark purple-black solid which was found to be diamagnetic. A subsequent X-ray crystallographic study of the new compound showed it to be the half-sandwich complex cis-{(?5-C5H2-(t-Bu))2(CMe2)2}Ru2(?-Cl)2Cl2 (5), containing RuII / RuII metal centers. The preferred way to synthesize 5 is to bypass the filtration and isolation step of the purple intermediate and to just remove the MeOH solve nt from the crude reactionmixture, add CHCl3, and heat to 80  °C for 15 min to give 5 in 28% yield (Scheme 2). The Structure of 5 shows a Ru?Ru single bond with a bond length of 2.7057(3) A, which would explain the diamagnetic nature of 5. Evidence for the RuII/RuII core is provided by the dissolution of the purple solid in MeCN to form cis-[{(?5-C5H2(t-Bu))2(CMe2)2}Ru2(MeCN)4(?-Cl)]+ (6), Complex 6 can also be synthesized by the reduction of 5 using Zn dust in MeCN and isolated in 62% yield (Scheme 3) The authors have successfully alkylated the 2,6-positions of the doubly linked dicyclopentadiene ligand 1a,b with either Me or tertbutylgroups. When the alkyl groups are tert-butyl groups, the resulting ligand reacts with RuCl3 ·3H2O to yield 5, the doubly linked analogue of [CpRuCl2]2 and [Cp*RuCl2]2. 5 can be reduced with Zn in MeCN to yield 6, an acetonitrile complex with a bridging chloro ligand. The bridging chloro ligand in 6 can be removed by the addition of AgOTf to yield 7, a ruthenium complex containing only the doubly linked dicyclopentadienyland acetonitrile ligands. Chin, R.

Coming of Age Essay Example for Free

Coming of Age Essay Around the world there are many themes that we find over and over in many cultures and from many periods in time. One of the reoccurring themes that everyone goes through in the lifetime is the theme of coming of age. This occurs when a young person goes through the transition from childhood to adulthood and has life experiences that matures a person. We all have experienced a coming of age story by reading them in books, seeing them on TV or in movies, or maybe even personal experiences based on ones culture. It’s clear that coming of age is a crucial element of our self-representations and conceptions. Generally, all of living is a process of coming of age as seen in the novel, Catcher in the Rye. Holden Caulfield, who is sixteen-year-old boy with the mind of a ten year old. He thinks of innocence as important in the beginning of the novel. But later on in the book, Holden slowly grows to be an adult. For example, when Holden gets soaking wet by rain when he is watching his little sister ride the carousal he â€Å"felt so damn happy all of a sudden†(213). This symbolizes Holden entering adulthood because he realizes the happiness in life. He realizes that he is too big for the carousel and is happy that his sister is happy. Holden’s childish personality continued to wash away as he reached a stage of maturity. Over the course of the novel, To Kill a Mockingbird, Scout is taken from a position of innocence, in which she believes that she is safe and that there aren’t many â€Å"bad people† in the world, to the position where she has witnessed some of the bad things that have happened but realizes that she is not entirely safe. That is tested at the end of the novel when Scout was attacked while walking home with her brother Jem. Similarities were show in The Adventures of Huckleberry Finn. Hucks maturity begins to grow as he first starts to show emotions toward a runaway slave, and by the end of the novel, has grown up to the point where, when Jim, is captured, Huck decides to give up playing games after Tom is shot to ensure that he would get medical attention that he needed. In an episode of Malcolm in the Middle it revolved around Malcolm trying to help his classmate Dabney get into a paintball match despite the resistance of Dabneys overbearing mom. Once Dabney unleashes years of repressed aggression, his mom comes around to try to drag him off. Dabney reacts back by saying â€Å" I’m no longer your little boy anymore. I’m your little man† showing that Dabney has matured and stands up and says what he believes. In the movie Edward Scissorhands, Edward is taken in by a family who he depends on. The family teach him how to think for himself so that one day he can gain the independence that is necessary for him to go out on his own. Edward living off of the familys support and trying things for himself is a coming of age process in itself. When he starts acting out and making his own decisions he is transitioning into an independent mindset that eventually allowed him to make the choice of living alone and fend for himself. Roman Catholics believe that Confirmation â€Å".. completes the process of initiation into the community and it matures the soul for the work ahead.. During confirmation God the Holy Spirit comes upon the person, accompanied by God the Father and God the Son, just as he did at Pentecost. †(Acts 2:1–4) Those who have been confirmed are called â€Å"Soldiers of God†. This refers to their spiritual duty to fight evil, darkness, and Satan. In Nigeria, young girls known as Iriabo spend several weeks in â€Å"fattening rooms† being pampered and wearing copper coils around their legs to restrict movement as part of a ritual marking their official transition into womanhood. In Senegal, Bassari boys undergoing the Kore rite and are taken into a sacred forest where they experience a symbolic death and a return to infancy, a state of ritual purity from where they are reborn as mature members of the community. (Hipple) Ultimately, the coming of age experience is a very much so significant time in ones life. People have to continue to find themselves and explore who they are even after the coming of age experience. It has lasting effects on a person as it has an impact on our dreams and desires that we want to fit into our world.

A Womans Place by Naomi Wolf :: Feminism

The True Woman "A Woman’s Place", the name of the commencement speech given by Naomi Wolf at the Scripps College graduation in 1992; contrasts the independent and the dependent woman. In today’s society, there are two different types of women: the woman who has a good head on her shoulders and knows where she is going in the world, and the woman who seeks dependence within the masculine world. Just as they were thirty years ago, women are still not considered to be equal to men. They are more or less looked at as being second to men. Naomi Wolf is a Jewish feminist writer who supports the independent woman. She was a Rhodes Scholar at Oxford University and graduated from Yale in 1984. Since then, Wolf has written two books that she is very well known for. She wrote her first book, titled The Beauty Myth, when she was twenty-nine years old. This book talks about women and how they feel beauty is one of the most important factors that will get you anything or anywhere. Her second book Fire With Fire was written in 1993. This book is about women taking control and not being victimized. Wolf is said to be a headstrong feminist that really believes in women’s power. In her commencement speech she mentions four factors of knowledge that she believes are mandatory for women to remedy. Her idea of a true or good woman is a strong woman who knows what she wants from life, is out to succeed, and will survive. An untrue or bad woman is a lady that is weak, that has a tendency to get run over, and has no real ambition for what she wants to do with her life. Wolf says that in order to become a headstrong, successful woman, one needs to redefine becoming a woman. Women have many different ways to clarify becoming women. According to Wolf, men have it a lot easier; however, most people in society would not agree with this. Boys have just as hard of a time becoming a man as a girl does becoming a woman. One might believe that Wolf is trying to say a women needs to redefine herself in order to have a place to start, so she can figure out what she wants to be and where she wants to go.

Western and Eastern Architecture

Culture and traditions have been an important component in influencing the development and creation of both Chinese and Roman architecture. It is through these norms that standards and perceptions of beauty are created. Each facet is deeply rooted in its ability to showcase the variety of actions from the structural foundations towards internal arrangements. These ideas then constitute the relevant ideas that have transformed the way construction and design is manifested within the boundaries of each culture. In the end, these differences created similarities and differences in approaches that harnessed each one’s individuality and contribution to the world today. On one aspect, we see the Roman architecture which bases its definition and construction of structures and buildings under a prescribed standard and format. These prevailing concepts have evolved through time under the pioneering Roman thinkers during the time. Under this process, a system for construction was introduced with by using important tenets such as geometry and mathematics that denote synchronization and order of things. Through this, the Romans advocate the relevance of proportion, both in exterior and interior design. It is through this that they are able to create their own distinct mark such as the formation of tablinum, atrium and peristyle courtyards. Comparing this with Chinese architecture, it can be argued that the overall design and architecture is considered to be free flowing. The plan captures the relevance of aesthetics by capturing the elements of nature and blending them accordingly with the both in the interior and exterior of the structure. It is through these actions that the idea of harmonization and being one with the overall surroundings becomes important. In addition, incorporation of natural elements such as trees and plants are also some distinct facets practiced by the Chinese. Moreover, adopting relative natural elements to these structures also necessitates generating freedom and ability to garner wholeness. Seeing these relevant differences, there are also similarities between these distinct approaches in viewing architecture and design. One relevant parallelism that can be seen in this process is that both approaches denote a system and standard of measurement and design. Though the Chinese may not be too strict about this and often tries to cover this up, the two ideas exhibit relevant attention to such facet and helps them apply significant ideas that contribute the creation of magnificent structures. Another significant similarity between these two styles is their ability to dig deep within their cultural backgrounds and affiliations to come up with standards and processes of how to construct and design structures. Take for example, the Chinese model for Buddhism and its relevance with being one with nature (Zen) has been the core concepts that generate such buildings. On the other hand, for the Romans, it is their constant passion for architecture and magnificent design that has enabled them to come up with ideas such as Coliseums, arched domes, and public baths. These similarities in turn foster their individuality as each approach makes their distinct mark in the overall application and design process. It may be true that each one possesses similar building foundations however; each one targets a different path in its application. With their ability to fabricate unique sets of designs, both the Chinese and Romans were able to create a framework that is encompassing and facilitative towards the growth of their relative inventiveness and capture the essence of their cultural heritage and practice.

Sarnath

The Buddha went from Bodhgaya to Sarnath about 5 weeks after his enlightenment. Before Gautama (the Buddha-to-be) attained enlightenment, he gave up his austere penances and his friends, the Pancavaggiya monks, left him and went to Isipatana. [4] After attaining Enlightenment the Buddha, leaving Uruvela, travelled to the Isipatana to Join and teach them. He went to them because, using his spiritual powers, he had seen that his five former companions would be able to understand Dharma quickly.While travelling to Sarnath, Gautama Buddha had to cross the Ganges. Having no money with which to pay the ferryman, he crossed the Ganges through the air. When King Bimbis ¤ra heard of this, he abolished the toll for ascetics. When Gautama Buddha found his five former companions, he taught them, they understood and as a result they also became enlightened. At that time the Sangha, the community of the enlightened ones, was founded. The sermon Buddha gave to the five monks was his irst sermon, called the Dhammacakkappavattana Sutta.It was given on the full-moon day of Asalha PuJa. [5] Buddha subsequently also spent his first rainy season at Sarnath[6] at the Mulagandhakuti. The Sangha had grown to 60 in number (after Yasa and his friends had become monks), and Buddha sent them out in all directions to travel alone and teach the Dharma. All 60 monks were Arahants. Several other incidents connected with the Buddha, besides the preaching of the first sermon, are entioned as having taken place in Isipatana.Here it was that one day at dawn Yasa came to the Buddha and became an Arahant. [7] It was at Isipatana, too, that the rule was passed prohibiting the use of sandals made of talipot leaves. [8] On another occasion when the Buddha was staying at Isipatana, having gone there from R ¤Jagaha, he instituted rules forbidding the use of certain kinds of flesh, including human flesh. [9] Twice, while the Buddha was at Isipatana, M ¤ra visited him but had to go away discomfited. [10]

How to Measure Motion in Plate Tectonics

How to Measure Motion in Plate Tectonics The lithospheric plates are the sections of Earths crust and upper mantle that move- very slowly- over the lower mantle below. We know that these plates move from two different lines of evidence- geodetic and geologic- which allow us to trace their movements back in geologic time. Geodetic Plate Motion Geodesy, the science of measuring the Earths shape and positions on it, allows us to measure plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earths surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell. The longer we record this information, the more accurate it becomes, and in much of the world, the numbers are already quite precise. Another thing GPS can show us is tectonic movements within plates. One assumption behind plate tectonics is that the lithosphere is rigid, and indeed that is still a sound and useful assumption. But parts of the plates are soft in comparison, like the Tibetan Plateau and the western American mountain belts. GPS data helps us separate blocks that move independently, even if only by a few millimeters per year. In the United States, the Sierra Nevada and Baja California micro-plates have been distinguished this way. Geologic Plate Motion: Present Three different geologic methods help determine the trajectories of plates: paleomagnetic, geometric, and seismic. The paleomagnetic method is based on the Earths magnetic field. In every volcanic eruption, iron-bearing minerals (mostly magnetite) become magnetized by the prevailing field as they cool. The direction in which theyre magnetized points to the nearest magnetic pole. Because oceanic lithosphere forms continuously by volcanism at spreading ridges, the whole oceanic plate bears a consistent magnetic signature. When the Earths magnetic field reverses direction, as it does for reasons not fully understood, the new rock takes on the reversed signature. Thus most of the seafloor has a striped pattern of magnetizations as if it were a piece of paper emerging from a fax machine (only its symmetrical across the spreading center). The differences in magnetization are slight, but sensitive magnetometers on ships and aircraft can detect them. The most recent magnetic-field reversal was 781,000 years ago, so mapping that reversal gives us a good idea of plate movements in the most recent geologic past. The geometric method gives us the spreading direction to go with the spreading speed. Its based on the transform faults along the mid-ocean ridges. If you look at a spreading ridge on a map, it has a stair-step pattern of segments at right angles. If the spreading segments are the treads, the transforms are the risers that connect them. Carefully measured, these transforms reveal directions of spread. With plate speeds and directions, we have velocities that can be plugged into equations. These velocities match the GPS measurements nicely. Seismic methods use the focal mechanisms of earthquakes to detect the orientation of faults. Although less accurate than paleomagnetic mapping and geometry, these methods are useful for measuring plate movements in parts of the globe that arent well mapped and have fewer GPS stations. Geologic Plate Motion: Past We can extend measurements into the geologic past in several ways. The simplest one is to extend paleomagnetic maps of the oceanic plates out from the spreading centers. Magnetic maps of the seafloor translate precisely into age maps. These maps also reveal how the plates changed velocity as collisions jostled them into rearrangements. Unfortunately, the seafloor is relatively young, no more than about 200 million years old, because it eventually disappears beneath other plates by subduction. As we look deeper into the past, we must rely more and more on paleomagnetism in continental rocks. As plate movements have rotated the continents, the ancient rocks have turned with them, and where their minerals once indicated north, they now point somewhere else, toward apparent poles. When you plot these apparent poles on a map, they appear to wander away from true north as rock ages go back in time. In fact, north does not change (usually), and the wandering paleo-poles tell a story of wandering continents. Together, the methods listed above allow us to produce an integrated timeline of the movement of the lithospheric plates, a tectonic travelogue that leads smoothly up to the present.

Stakeholder Society essays

Stakeholder Society essays Social equality has long been a dream of many Americans. It would be wonderful to live in a society where everyone had equal or nearly equal opportunities, but the United States will never be the land of equal opportunity because it is just not going to happen because we have been socially stratified for too long to ever be equal. However, as Ackerman and Alstott propose in The Stakeholder Society, we may be able to offer Americans an equal monetary offering from the government, but is this going to work? Ackerman and Alstott propose to simply raise taxes 2% and give every American eighty thousand dollars sometime in there twenties, considering that they are stable minded and graduated from high school. Recipients would not receive the eighty thousand dollars in one lump sum, but over a period of a few years. When the recipient dies, if they have sufficient funds, they repay the eighty thousand dollars back to the government where it will be used for redistribution. At first, this sounds like a great idea, however, there are many underlying problems. First of all, there are way too many irresponsible people who will blow their money on toys such as new cars, electronics, or on drugs and become drug addicts. Giving a check for twenty thousand dollars to a twenty-five year old and telling them that they can do whatever they please with it is pretty brave. Giving large handouts will also teach people to spend irresponsibly and not manage their money. They will not know what to do when the money runs out and they are still earning seven dollars an hour at some job that they hate. Instead of giving any twenty-some year old American eighty thousand dollars, I believe the government should provide a program to provide funding government funding for college. Every American should be able to go to college for free. This is the time when many people accrue large debts through loans and living expenses bu ...

How to Register for AP Tests and Classes

How to Register for AP Tests and Classes SAT / ACT Prep Online Guides and Tips Wondering how to register for AP classes and tests? Get a complete guide to AP registration here – even if you’re homeschooled or your local school doesn’t have the AP program. How to Register for AP Classes The AP Registration process varies from school to school. Typically, you go through the regular class sign-up process to take APs, as long as you have taken the necessary pre-requisite classes. For example, many schools require students to take an introductory biology course before they can enroll in AP Biology. Your school's course catalog should list the necessary pre-requisites for each AP class. In some schools, you have to pass a placement test to register for an AP class. For example, my school required students to test into AP Calculus BC as well as AP Calculus AB – even if they had taken math up through Pre-Calculus. Based on your test score, you were placed into either Calculus BC, Calculus AB, or regular (non-AP) Calculus. We recommend asking one of your current teachers or the guidance counseling office about how to sign up for AP Classes at your school. They can let you know if there are any specific protocols outside of your school’s typical registration process, like placement tests or class size limits. If you attend a school without AP classes or you're homeschooled, you don't have to officially register for an AP class. You just need to register for the AP Exam later in the year (more on that below). It's up to you to either take a class that teaches most of the same material (e.g., taking a United States History course if you want to take the AP United States History exam) or to self-study during the year. How to Register for AP Tests If You Attend a School with AP Classes If you’re taking AP classes, your AP teacher typically alerts you to your school’s AP test sign-up process. They should inform you of the deadlines to register for the test. Some even walk you through the registration process! If you haven’t heard anything from your AP teacher yet or are just curious about your school's AP test sign-up protocol, track down your school’s AP Coordinator to find out the dates and deadlines at your school. AP Coordinator? Who's that? Each school that offers AP classes has a staff member (often a guidance counselor) who is given this title. It’s officially their job to handle AP test registration and coordinate with the College Board. If you don’t know who this person is, either check in with your guidance counselor or one of your AP teachers, they should know. Keep in mind you have to register for AP exams through your school, there is no way to register online. (Some students get confused because other College Board tests, like the SAT and SAT Subject tests, have online registration.) As part of your registration, you’ll turn in the $92 exam fee to the AP coordinator. And that price is per exam, by the way. (See ourpost on AP Exam costs to learn about getting financial aid for AP tests!) If You're Homeschooled or Your School Doesn't Have AP Classes If you’re homeschooled, or you attend a school without the AP program and are self-studying, you can still arrange to take AP Exams at a nearby participating AP school. To do this, you’ll contact the AP program itself. Contact AP Services no later than March 1st of the year you want to test, and they’ll give you the names of local, participating AP schools willing to test outside students, as well as the phone number of the AP coordinator at that school. This is the contact information for AP Services. Remember, you have to contact them to get the contact info of a local school that will give you the AP exams: Phone: 888-225-5427 International callers: 212-632-1780 Fax: 610-290-8979 Email:apstudents@info.collegeboard.org Prepare a list of the AP Exams you are interested in taking before you call – this will help College Board find a school you can test at. Once you get their info from AP Services, call the AP Coordinators at the local school no later than March 15th to set up your testing. When calling Coordinators to arrange testing, make sure to tell them the following: That you got their contact information from College Board. That you are trying to find a school that will give AP exams to homeschooled students or students from schools that do not offer AP Exams. The AP exams you want to take. If you have a documented disability that requires accommodations. Once you locate a school that will host you, that school's AP Coordinator is responsible for ordering your exam materials, telling you when and where to report for the exams, and collecting your fees (which may be higher than the typical $92 to cover the school’s additional proctoring or administration costs). One last thing: your host school must administer the exams for you. The school cannot forward the AP exams to you or your school. That means on exam days, you'll have to travel to your host school (and be absent from your regular classes). Some Additional Guidelines for Signing Up Signing up for AP classes and tests is usually straightforward. Plus, there aren't restrictions on how many classes you can take each year (unless your school has its own rules). You can take as many AP Exams as can fit into your schedule. The AP Program doesn’t even require you to take an AP class before taking an AP Exam. The only restriction on registration from College Board is that you can’t take both Calculus AB and Calculus BC within the same year. This is because Calculus BC includes all of the material in Calculus AB – you even get an AB Subscore when you take Calculus BC! AP Calculus BC is essentially two math classes in one! If two of the exams you want to take are scheduled for the same time, ask your school’s AP Coordinator for information about taking one of the exams during the late-testing period. The late-testing period occurs in late May, to accommodate tests that overlap or students that run into last-minute problems like an injury. In general, popular AP exams don’t tend to overlap, so you’re more likely to run into this problem if you’re taking a more niche exam like Art History or Japanese. On Exam Day Keep these guidelines in mind to make sure you are ready to test in May once you’re registered! You have to bring a valid government- or school-issued photo ID with you to the exam. Even though the test is administered by your school, and all your teachers know you, you have to follow this rule. You’ll be turned away without your ID, so don’t forget it! If you have approval from the College Board to test with accommodations, you have to bring your Student Accommodation Letter. If you attend a school that doesn’t offer AP, you should not use the school code for the school where you are testing. Instead, make sure to use your own school’s code so your exam score(s) will be reported to your school. This means you need to get your school’s six-digit code from your principal or school counselor before exam day. If you are home-schooled, use the state or international home-school/self-study code that will be given to you on the day of the exam. What’s Next? Which AP exams should you take?

Personal Wellness Living Plan Article Example | Topics and Well Written Essays - 500 words

Personal Wellness Living Plan - Article Example Personally, my goal is to work on reducing my body weight from currently 170kg to 80kg. This is a hard task, and for me to achieve it, a lot of disciple and advice from health officials will be very vital. One can reduce weight in many different ways. However, before resorting anyone of them, it is critical to consult medical practitioners to advise you on the best method suitable for you. Health experts have always advised that eating a healthy diet is one of the best ways to reduce the body weight (Moreno 48). Healthy weight reduction takes time and energy, but simple changes in the lifestyle like eating a healthy diet can greatly help in the process. Keeping proper food and exercise diary will be key for me to achieve my goal. A regular workout regime will be developed, and my diet is modified according to my doctor’s advice so as to achieve a healthy weight loss. The implementation of this plan will not be easy as I will have to adjust to some routines that I was never used to before. Having to eat fewer carbohydrates will specifically be tough for me as some of my favorite meals fall in this category of foods. To overcome all these difficulties, I will count on the support of my family members. They will play a big part in my transformation process, offering moral support and guidance. Despite all the challenges I am likely to face in my dream to lower my body weight, my motivation is to reduce the risks of getting high blood pressure and other diseases related to body weight.

BAIDU & GOOGLE Research Paper Example | Topics and Well Written Essays - 1000 words

BAIDU & GOOGLE - Research Paper Example The reasons of the above outcome are analyzed below; emphasis is given on the criteria on which the expansion of Google across the Chinese market was based. The reasons for the failure of Google in the Chinese market are also critically discussed. Despite its success in the global market, Google has not managed to acquire the dominance of the Chinese market as an advanced Search Engine machine. In fact, in accordance with a report published by the Search Engine Journal, the share of Google in the Chinese market has been estimated to 32.8% - whereas Baidu controls ‘the 56.8% of the search share’ (Baker 2008). It should be noted though that no significant competition seems to exist in the specific sector – it is noted that Baidu and Google control the 90% of the search share in China. ... wever, the time lost has been significant and Google is currently trying to cover the gap caused because of its short-term exit from the Chinese market. However, in accordance with Hotchkiss (2011) the reasons for the failure of Google in China are not just regulatory; it seems that the specific search engine cannot respond – at least not as effectively as – to the technical demands of the specific sector – emphasis is given on the structure of Chinese characters and the severe delays that can be reported when using these characters in a Search Engine machine. Moreover, it seems that the development of Google China has not helped towards the resolution of the above problem – as it could be possibly expected. The above problem is made clear through the following example: in a study developed by Hotchkiss (2011) in North America and China the time of response of Search Engines was set under comparison. In the case of search through Google – using West ern language – a time period of 8 up to 10 seconds has been required to retrieve the results. However, when using Google China the response to a search query ‘took about 30 seconds, and with Baidu over 55 seconds’ (Hotchkiss 2011). Apart from the time of response, the presentation of the findings is also problematic – referring to Google China. It is explained by Hotchkiss (2011) that the vertical scan (based on relevance) used commonly for checking the results cannot work in the case of Google China; instead it is necessary to check the whole list of results in order to select the required one (Hotchkiss 2011). In accordance with the above, the ability of Google to respond to the needs of Chinese people can be strongly doubted. At the next level, the following fact should be mentioned: in a recent (2011)

The Realities of leadership within a retail organisation Essay

The Realities of leadership within a retail organisation - Essay Example How can I give what I do not have, and how can I help others accept change if I am not ready to do the same? One day, our management decided to institute changes on working hours in the store as part of a new model store blueprint. The policy altered each worker’s start and finish times, and break times were shortened to half an hour. For those working more than eight hours, an hour’s break was allowed. We knew that most of the staff would react negatively to the proposal, and that resistance had been building up in many of them. I was given a tight deadline to implement the change in my store. The task was daunting, but I was confident because I had the tools needed to plan and execute the change, ready to confront and solve most of the problems that would arise. What were those tools, how did I use them, and why? Lou V. Gerstner, who as IBM CEO saved the company at a time of crisis, found that â€Å"changing the attitudes and behaviour of people is very hard to accomplish. You can’t simply give speeches, write a new credo†¦and declare that people have to change. What managers can do is create the conditions for transformation. You provide incentives. You have to trust. In the end, the workers themselves decide to change† (Gerstner, 2002). Knowing why people resist change is the first step to help them change. Reflecting on my experiences, I know three main reasons why people resist change: uncertainty makes them nervous and afraid, they do not see how change can be good for them, and coping with change is inconvenient because it requires effort. Equipped with this knowledge, I can help people change by making a plan to deal with each of these reasons. First, I eliminated uncertainty through communication, helping the workers build up their trust in management through me by discussing with the workers the reasons behind the policy decision, like better efficiency, increased sales, and more satisfied

Retail Marketing and Logistics - Case Study Example This paper will identify several theories and concepts on the subject of retail marketing and logistics. The focus of the paper is on one of the biggest international retail stores - 7-Eleven. The company, 7-Eleven, has a worldwide chain of convenience store in different countries. It is a leading operator, franchisor and licensor of convenience stores with 34,800 stores in 17 countries. The name of the company was derived from 7am to 11pm, its operating hours during the early stages of its existence. Today, the convenience stores are open 24 hours a day, 7 days a week. The company started its humble beginning in Dallas, Texas on 1927 when an enterprising dock employee began offering milk, bread and eggs aside from its core business of selling blocks of ice. The first store was opened during Sundays and evenings; a time when grocery stores were closed. The business idea of an entrepreneur regarding convenience retailing was widely accepted by satisfied customers and became profitable through increased sales. Ironically, the story of 7-Eleven can be considered as the story of convenience shopping because it is the company that pioneered and invested on the idea. In 1991, two Japanese companies invested millions of dollar to finance the company in order to emerge from bankruptcy. As a result, 7-Eleven became a wholly owned subsidiary of Seven Eleven Japan Company which controls 70% of the company's stocks. The convenience stores in US and the rest of the world are mostly operated through licensees and affiliates. The paper will tackle the current positioning strategy of the company worldwide. 7-Eleven is positioned as a convenience retail store of consumer goods with diverse products and services that provides easy access to end-consumers. It is in the marketing strategies of the company and its brand name in the market that alleviated the market leadership of the company in convenience stores industry segment. The paper will also explore the competitive environment of global retailing industry where 7-Eleven plays as well as the different business strategies that the company employs in order to be recognised as the world's number one convenience store. At the end, the paper provides several recommendations for the company in order to sustain its growth in the retail industry. Identified opportunities for the company includes further geographical expansions and investment in private label brands as well as natural, organic products. Current Positioning Strategy 7-Eleven stores are positioned as low price general merchandise store that operates for consumer's convenience shopping. The convenience stores are saturated in high income and large traffic locations in order to exploit consumer spending. The strategy of the company is to become the preferred convenience store of consumers anytime anywhere. Retail Marketing Mix - Lauterborn's 4 Cs Consumer wants and needs The relationship marketing strategies of 7-Eleven follows the first C of retail marketing mix. The company identifies the customer's preferences and tastes as well as its buying trend through an integrated information system and in depth analysis of data. As discussed later on the paper, the layout of 7-Eleven store is carefully evaluated and is changed several times a day in order to respond to the buying

Write summery about what these websites are about - Annotated Bibliography Example and Northern Development Canada that was first called Indian and Northern Affairs Canada (INAC) is discriminating in fairly providing funds for children of aboriginal reserves. They also claim that the children are also being denied to welfare benefits of reserves. . It is not only about the indigenous children who are suffering at the hands of government but there are other issues like water crisis and more than 582 indigenous women murdered and missing but no action has been taken so far by the Canadian government. That’s why, the society has sued against the INAC for showing this acute prejudice. The plea has been filed to Canadian Human rights commission alleging that the federal government has differentiated between the children of first nations and those originally from Canada on racial basis. Â  The society and INAC worked for several years to eliminate inequality but all efforts by society went to vain as the federal government did not show any response to efforts done so far but failed badly to develop solutions to redress inequalities among children on racial basis. Canadian Human Rights Commission found in 1977, is an autonomous government body that deals with the Canadian Human Rights Act. The Canadian commission has the right to investigate complaints filed on racial and discriminatory basis under federal jurisdiction and also has jurisprudence to hear the cases filed in favour of children on reserves of first nations. The society has also filed another plea to the commission in 2010, accusing that the Aboriginal and INAC are not only prejudiced against the children of first nations but they have racist attitudes against the FNCFC society too as they excluded the society’s executive director, Cindy Blackstock from the meetings aimed at development of first nations. The society has accused that the handling of society’s members by INAC has been ridiculous so far and was based on retaliation. The commission later on directed the case to the

Land Registration Act Reforms Essay Example | Topics and Well Written Essays - 1500 words

Land Registration Act Reforms - Essay Example Previous to this act, the unregistered lands were regulated by the 1925 property legislation and the common law and equity rules. The creation of the 2002 Land Registration Act brings about a revolutionary change in the way conveyancing in Wales and England is carried on, and also to create a modern land registration system1. The primary aim of the Land Registration Act 2002 is to significantly reduce the amount of overriding interests which can potentially bind a registered title purchaser and replace most of them with entries which are registrable. 2. Registered Land Registered land refers to the land where the title of the land has been registered into the Land Registry and the objective is to make an registered entry of ownership of land and also of the third party which is involved into the registration process. The theory states the purchaser may not need to look other than into the register to make enquiries regarding the price of land purchased. In actual condition, if overri ding interests are applicable on a piece of land, which may happen even in case when the buyer is bound to the land and the name of purchaser appears nowhere into the register, then the purchaser needs to look far beyond the register. Registered land ownership is often more striking than the ownership of unregistered land.2 Wherever the title has been registered, they are bound to be ascertainable and registered from the register; however it is often subject to overriding interests. 3. Aspects of Overriding Interests Overriding interests are mainly the interests that are given for registered land which has not been registered and it binds the purchaser to the land. Overriding interests can be divided into two categories - the overriding on the first registrations (mentioned under LRA 2002 of s. 1) and the overriding registered disposition (mentioned under LRA 2002, s. 3). In both the schedules, similar categories of interests' terms are mentioned, although there are many restriction s within the scope of these interests. Overriding interests is applicable on short leases and it provides the right to people who are actually occupying the land,3 while it does not include mortgages of registered land or estates, the third parties which are registered against the estate and the short term lease which overrides minor interests. If the third party is overriding interests against the registered estate, then it automatically gets the right to bind the buyers. This can be compared to the legal interests, which is provided against unregistered title. If the third party does not override, then it becomes the minor interest which will bind the purchasers only in a condition when it is protected through some type of register entry (This is comparable to the land charges required for registration). It is stated by the mirror principle that until it affects the title, the legal use of the enjoyment of the land can never be complete and this means the category should be abolis hed or it should be significantly reduced. There are sometimes a number of interests which includes the legal and equitable interests which are not on the register and it binds the purchaser of the land, irrespective of the inconsistency of notice with the concept of title registration.4 Other related aspects of the proposals of overriding intere

Design of a Low Voltage CMOS Transconductance Amplifier

Design of a Low Voltage CMOS Transconductance Amplifier This project aims to illustrate the design and simulation of a Low Voltage Complementary Metal Oxide Semi Conductor (CMOS) Transconductance Amplifier (OTA) with an improved power consumption, Direct Current (DC) gain and bandwidth. Two techniques were introduced for linearization: Pseudo Differential Pairs and Source degeneration under nano-scale technology. The nonlinearity, which is caused by the short length effect due to the small size of transistor can be reduced using linearization techniques, Two techniques were introduced for linearization: Pseudo Differential Pairs and Source degeneration, were both go under nano-scale CMOS technology. The proposed OTA requires a proper control system, where the common-mode control system has been designed for system stability . The results of this implementation are: power consumption of (x), DC gain of (x) , a size of (x)  µ, number of transistors (x) . All the work was simulated using the Advances Design System ( ADS ) , under 130nm CMOS Technology. 1.1 Motivation The huge pace in technology and the growing demand of electronic devices makes the Integrated Circuit ( IC ) designers think twice about low power and low voltage with the trade of the Threshold Voltage ( VT ) which doesnt scale down when compared to the power supply. Throughout the years, designing analog integrated circuits has been challenging, where the power supply is being reduced due to the demand of technology which requires to scale down the total power. The Operational Transconductance Amplià ¯Ã‚ ¬Ã‚ er (OTA) is recognized to be one of the most important basic building blocks in analog ,mixed mode circuits, filters, including multipliers, voltage control oscillators, and Very Large Scale Integrations ( VLSI ) applications, where the VLSI technology is the process of creating ICs by combining several transistors into a single chip. In such applications the OTA is the key circuit to such design, OTA at the input of the block determines the efficiency of the overall system, hence improving the performance of the OTA block is critical for enhancing the overall module performance. Operational Transconductance Amplifier An OTA main purpose is to convert its input voltage to the desired output current; i.e. in other words an OTA is a voltage controlled current source, where Gm is the Transconductance with a unit (Ampere/Volt). In real life circuits, harmonics are introduced, and nonlinearity should be taken into consideration which caused by the short channel effect of the transistors, the expression of the output current with Taylor series expansion can be as follow : where ai is determined by the implementation of the circuit. In order to achieve a proper OTA with the specifications mentioned, linear transformation factor should be implemented in the design to reduce harmonics, linearization methods have been developed through the years to solve the problem. 1.2 Objectives The main goal is to design a low voltage Transconductance CMOS amplifier which converts its input voltage to the desired output current with high linearity, which can be achieved by linearization techniques, Pseudo Differential Pair and Source degeneration techniques. 1.3 Realistic Constraints The listed below are the main constraints that should be taken into consideration for the design : 1.3.1. Economic Constraints: The student shall use the available simulation tools such as : Advanced Design System for simulation design, and Synopsys for layout . As for the design, the main goal is to reduce harmonic distortion, achieve high linearity, and to be able to transform the input voltage to the required output current with minimum size. Since the size of the transistors determine the size of IC , and the size contributes in the cost of the IC. The designed IC is being manufactured in fabrication laboratories. During the fabrication process, thousands of ICs are being etched onto a single blank wafer. After the testing process ,only percentages of the ICs are considered useable, and being distributed among electronic stores. 1.3.2. Manufacturability and Sustainability Constraints: The designed circuit shall be worked across process and temperature corners for improved yield. 1.3.3. Ethical and Safety Constraints: Documentation should not have more than 30% similarity on Turnitin. 1.3.4.

The total power consumption will be less than 15mW. The supply voltage will be less than 1 volt. Bandwidth should be larger than 50MHz DC gain should be larger than 20dB 1.5 Design Achieved The goal of this project was achieved by designing a low voltage CMOS transconductance amplifier using linearization techniques with high linearity, low power consumption of (x), DC gain of (x) , a cost of (x). 1.6 Task Distribution Work was done as a team; but some work was distributed to ensure every member has their own task. This is shown in the table below: Stage Details Marwa Marah Rateb All Research Reading papers Setting goals Design of Pseudo Differential Pair Design Build Design of Source Degeneration Design Build Design the Common Mode Design Build Connecting The circuitry ( suggested OTA ) Design Build Layout Design Build Documentation Ch.1 Ch.2 Ch.3 Ch.4 Ch.5 Table 1.1: division of labor 1.7 Organization The rest of the documentation illustrates the design characteristics where it goes as follows; Second chapter discusses the background and literature review of different approaches related to the same design. Third chapter discloses in detail the overall design, including the explanation of each linearization techniques, as well as justifying the region of each transistor. Forth chapter demonstrates the results of the design. To end with, chapter Five conclude the design, along with the future work which can be implemented to improve the design. 2.1 Transconductance Amplifier Topologies This project aims to design an Amplifier which able to convert its input voltage to the desired output current, with Pseudo Differential Pair and Source Degeneration as linearization techniques Varies architectures had been developed through the past years to build the basic OTA block Table 2.1 :comparison between three different papers Design Design Requirements Referring to chapter 1, the design shall meet the following requirements: The design uses CMOS based technology. The total power consumption will be less than 15mW. The supply voltage will be less than 1 volt. Bandwidth should be larger than 50MHz DC gain should be larger than 20dB Analysis of Requirements and Constraints In order to attain the design specifications mentioned in section 3.1, the requirements and constraints are clarified below Analysis of Design Requirements CMOS based technology CMOS circuits components are becoming the most desired to be implemented in nowadays technology, due to its low power consumption. Furthermore, its high speed when compared to other used technology. Power Consumption Supply Voltage Bandwidth DC gain Analysis of Design Constraints Economic Constraints Manufacturability and Sustainability Constraints The design should meet the proper operating temperature and environmental corners. The circuit topologies have been implemented using an advanced simulation that can foresee the behavior of the circuit under such circumstances. For instance, a high power circuitry will increase its temperature, thus the degradation of the performance in time, but if the circuit surpass in supreme corner, it is expected to have a longer life time. Ethical and Safety Constraints Documentation shouldnt exceed 30% similarity, citation should be considered along with stating proper referencing Design Approaches According to the cited papers in chapter 2 there are four different architectures for the converter design. All of these architectures cant be used to achieve the requirements of this project. The developed design discussed in the next section has the opportunity to achieve the requirements

How The Adams-Onís Treaty Affected The Growth Of Our Nation :: American America History

How The Adams-Onà ­s Treaty Affected The Growth Of Our Nation Americans were interested in further expansion and looked to the weak Spanish provinces of East and West Florida. The Spanish were reluctant to give up what is now Florida, but in the end they worked out an agreement called the Adams Onis Treaty. In this essay I will describe how the Americans eventually got these provinces, the set backs of the signing of the treaty, and how it effected the economic growth of our nation. Americans living in West Florida between the Iberville and Perdido Rivers declared their independence, and President Madison ordered the Governor of New Orleans Territory to take control of the independent land. The Americans now had control over half the territory they wanted but this did not satisfy them, this only made them more eager to gain control of East Florida. Almost two years after this event peace concluded, but Spain still had possession of East Florida. This time Spain only had two solutions to avoid a shameful political break down over this region. One was to gain support of a European ally, and the second was to get some form of honor in this event by winning some of the United States best land else where in North America. The first plan fell through, Britain and other European nations refused to help Spain. They eventually fell to having discussions with the United States. The American government was entirely willing to have discussion of the East Florida issue become the end result of all Spanish-American boundary questions. John Quincy Adams was the Secretary of State and was the person taking care of all discussions between the U.S. and Spain. He saw that this was a perfect time to try to extend the boundary to the Pacific Ocean. Luis de Onà ­s was the minister of Spain at the time and he was the Spanish representative to the U.S. His instructions from the Spanish government was to transfer the Florida's to the United States in return for the American settlement west of the Mississippi. Onis was also to get a promise that the United States would not give material aid to, or recognize the independence of Spain's colonies in South America because of their lack of cooperation. Difficulties came up over negotiating a satisfactory boundary in the West and also over the command to put American military in East Florida in 1818.

Market Opportunities for Soft Drink Companies Essay

Companies in the soft drink manufacturing industry are facing intense competition from the domestic and foreign brands,resulting in rising promotional costs and sinking profit margins. The consumers are going for real â€Å"value† for their money ,choosing drinks with better health value. Acurrent ban on sales of carbonates shows in the trend analysis given below:- {draw:frame} COMPANY GROWTH RATE Our company has shown a declining growth rate due to change in value perception and behavioural differences of consumers due to governmental bans all over the country. A public clarification would help us change the consumer perception. We need to make our core value based products to be fresh and relevant. We also need to sharpen our focus in this industry for maximum effect. {draw:frame} The trends of our own product offerings in the market are shown in the graph as below. Here we can notice a declining trend. {draw:frame} This declining trend can also be seen as a loss of our market segment to healthier drink options like fuit juices and water . It is quite evident in the graph given below:- {draw:frame} High sales volume in the water drinking segment and health juice segment shows that customer want better value and there perception is based on the changes in the microenvironment brought about by our competitors. There is a possibility of high â€Å"customer churn† in the future as our company’s sales decline. A 5 percent reduction in the customer defection rate can increase profits by 25 percent to 85 percent. According to the expectancy value model we ned to look into altering the beliefs about our brand which is effected by physical risk perceptions. Here we are seeing intense segment rivalry in our eange of products. Also there is lower entry barrier. The companies point of view needs to be visible on active information search. A customer’s decision to be loyal or defect from buying our products depends upon the large number of small encounters of the company which should lead to memorable customer experience.

Computer Can Replace Teacher Essay

There are some innovation and technology enthusiasts who claim that computer-based learning will soon replace teachers. Just take a look at some recent op-eds by Andy Kessler and Richard Galant. They point to the accessibility of information via the Internet and the recent advances in online instruction and adaptive learning as harbingers of teacher obsolescence. These assertions are alarming to those who advocate the importance of teachers, like Diane Ravitch and Wendy Kopp. They point to a strong body of research that affirms the importance of good teachers. So how do we make sense of this war of words and tumult of opinions? To one degree or another, both sides are overlooking important considerations. Those who proclaim that computers will replace teachers often naively reduce teaching to mere instruction and assessment. In doing so, they forget the true breadth and complexity of the job teachers perform. Computers are becoming better at providing customized direct instruction an d at assessing student mastery of foundational knowledge and skills. But good teachers do much more than present information and drill the fundamentals. High-quality teachers guide their students through activities and projects that stretch them to analyze, synthesize, and apply what they have learned across academic subjects and into the real world. They provide personalized, qualitative feedback to help students develop their critical and creative thinking. They create a classroom culture that intrinsically motivates students by honoring their hard work and by making academic achievement socially relevant. Going above and beyond the call of duty, many of the best teachers are driven by a â€Å"whatever-it-takes† attitude to ensure that all their students receive the resources and support needed to put them on a path to success in life. Those human aspects of good instruction are not going to be replaced by machines anytime soon. On the other side of the debate, those who emphasize the importance of traditional teachers often do not notice how unrealistic it is to provide high-quality teachers at scale in the current monolithic model of classroom-based instruction. They overlook the fact that the breadth and complexity of the job of good teaching makes it nearly impossible for most teachers to do all of the critical aspec ts of their job exceptionally well. Teachers are expected to design and execute daily lesson plans for multiple hours of the school day, orchestrate student learning activities, administer and grade student assessments, develop and implement efficient and effective classroom procedures, and differentiate their approaches for diverse student needs, all while managing the daily wild cards of student behavior. Additionally, we expect teachers to maintain close contact with parents, provide students with social and emotional support, perhaps offer after-school tutoring, sponsor student clubs, coach sports, organize school and community events, and shoulder many of our schools’ administrative duties. With all of these jobs crammed onto their plates, few teachers have the time, stamina, or cognitive and emotional capacity to do each job well. Under these circumstances, is it any surprise that so few teachers produce the results that we demand of them? Exceptional teachers are often put on pedestals in the media and in public debate, but these awesome individuals produce a level of work that is rarely sustainable and certainly not scalable. The model of monolithic classroom instruction from the late 1800s just wasn’t designed to allow teachers to meet 21st-century expectations. In fact, traditional classrooms were designed to prepare students for jobs in an industrial economy of the past. To meet this end, the system was set up to process seemingly homogeneous batches of similarly aged students through one-size-fits-all instruction. Undifferentiated instruction was acceptable back then because students only needed to understand math, science, and literature at a C or D level in order to â€Å"pass quality control,† receive their diplomas, and enter the workforce. Teaching might have been a reasonably manageable job back when these assumptions held true, but in the knowledge-based economy of today, the assumptions no longer hold and teaching becomes a heroic job. Despite the incredible challenges we face in providing good teachers at scale, there is a bright light at the end of the tunnel. The educators, in novators, and entrepreneurs that are now experimenting with blended learning are completely redesigning our models of instruction. Rather than merely layering technology on top of traditional classrooms, they are leveraging technology to transform the role of teachers, accelerate student learning, and magnify the impact of educators. Blended learning allows much of the work of basic instruction—like drilling multiplication tables or reviewing vocabulary words—to be offloaded to computers so that teachers can focus on the aspects of teaching that they find most rewarding, such as mentoring students and facilitating exploratory learning projects. Properly implemented blended learning does not eliminate teachers, but instead eliminates some of the job functions that teachers find most onerous. Technology will not improve our education system if we marginalize or eliminate teachers. Likewise, our education system will not meet modern needs at scale until we innovate beyond the factory-model classroom. Innovation may lead us to classroom setups and teacher roles that look very different from today, but a human element will always be an essential part of the equation. By framing the debate as technology vs. teachers, we create a false dichotomy. Instead, our conversations should focus on finding ways to let technology do what it does best so that we can leverage teachers to do what they do

Parents Influenced on Their Children

influenced of parents to their children Parental Influences on Personality: A Comparison of Trait and Phenomenological Theories Stu Dent SS# 123-45-6789 Psych 210: Theories of Personality Dr. Cervone — Fall, 2001 Parental Influences on Personality: A Comparison of Trait and Phenomenological Theories A seemingly obvious fact about human nature is that our personality is influenced by our parents. Intuitively, it seems as if the way our parents raise us exerts an enduring influence on the nature of our personality.By teaching certain types of behavior and by punishing actions of which they disapprove, parents may significantly influence the behavioral and emotional styles of their children. This intuition, however, contrasts with a second one. Common knowledge tells us that siblings often differ greatly from one another. One brother may be outgoing, the other shy. One sister may be conservative, the other liberal. Since siblings have the same parents, and parents tend to treat t heir children similarly, such examples seem to suggest that parents’ style of child rearing might make little difference to the personality of their children.The question of parental influences on personality, then, is an interesting puzzle for scientific theory and research in personality psychology. Theories of personality have taken different viewpoints on the question of parental influences on personality. This paper addresses two theories that present contrasting views. These are the trait and phenomenological theories of personality. In the trait theories, the basic variables of the theory are people’s traits, that is, their â€Å"broad predispositions . . . to respond in particular ways† (Pervin & John, 2001, p. 26). Most trait theories try to identify a common set of traits that can be used to describe the personality of any individual. These â€Å"nomothetic† trait theories rely on the statistical procedure of factor analysis to identify dimensio ns that can be used summarize individual differences in personality traits. Researchers using this technique commonly identify a set of five trait dimensions. These Big Five personality traits include extroversion, neuroticism, conscientiousness, agreeableness, and openness to experience (Pervin & John, 2001).Once one identifies a set of basic traits in this manner, a primary question is to identify where the traits come from. Why do some people have more or less of a given trait than others? Almost all trait theorists have sought biological explanations for variations in traits. People are seen to inherit a given level of a trait in the same way that they might inherit hair color or height. This viewpoint is consistent with findings on genetics and personality, which indicate that identical twins’ personalities are far more similar than would be expected by chance (Pervin & John, 2001).The trait theories, then, have an interesting implication for the question of parental inf luences on personality. If personality is defined in terms of personality traits, and if traits are thought to be inherited, then parental styles of child rearing would appear to have little influence on children’s personality. The only influence parents would have on their children’s personality is a biological one. They pass their genes on to their children. According to the trait theories, parents interpersonal interactions with their children would exert little effect on the child’s personality development.A very different view is put forth by proponents of phenomenological theories of personality. The primary focus of the phenomenological theories is the individual’s subjective experience of their world, that is, their phenomenological experience (Pervin & John, 2001). In particular, people’s subjective experience of themselves, or their self-concept, is seen as the core of individuals’ personalities. Among the most prominent of the phe nomenological theories of personality is the self theory of Carl Rogers (Pervin & John, 2001).Rogers contended that people’s psychological experiences are not determined by objective events in the world, but by their subjective interpretations of these events. These interpretations, in turn, are heavily influenced by a person’s self concept. Specifically, people may experience psychological distress when they cannot integrate their daily experiences with their sense of who they really are, as might be manifested by a person’s saying that â€Å"I just haven’t been acting like myself lately. † Alternatively, a person might feel guilty or depressed if their ctions do not meet their â€Å"ideal self,† that is, the person’s subjective sense of what they ideally should be like; in such circumstances, a person might report that â€Å"I’m disappointed with myself. † People’s self-views, then, are a primary determinant of their overall experiences. With regard to the question of parental influences, Rogers’ phenomenological theory has a very different implication than that deriving from trait theory. According to Rogers, self concept, like other aspects of phenomenological experience, is not inherited but instead develops gradually as people interact with the world and the other people around them.Rogers suggests that people develop a positive self-concept if they experience â€Å"unconditional positive regard,† that is, if people consistently respect and accept them for who they really are. People who experience unconditional positive regard, then, should have a positive view of self that enables them to approach daily activities in an open-minded, psychologically flexible and creative manner. In contrast, less positive personality development occurs if people experience â€Å"conditions of worth,† that is, if other people establish criteria, or conditions, for what is valued be havior.Such individuals may experience a more negative view of self that leads them to approach life activities in a more cautious, tentative, self-critical, and unconfident style. Since parents are generally the major source of influence in the early years of child development, the extent to which parents display unconditional positive regard to their children, as opposed to imposing conditions of worth, should influence long-term personality development. A primary question, then, is how one might be able to test these theories one against the other.Since personality theorists are attempting to development conceptions of human nature that can be evaluated by objective empirical evidence, it should be possible to marshal scientific evidence that bears on the relative merits of the two theories. For the question of parental influences on personality, one key source of evidence would be longitudinal studies, that is, studies that examine the same individuals across a long period of ti me. Ideally, such work would measure aspects of child rearing early in life and determine whether they predict personality characteristics as measured later in life.Such a study has been conducted by Harrington, Block, & Block (1987). They studied a large group of people at two points in time: early childhood and adolescence. During early childhood, the researchers obtained measures of the degree to which each child’s parents exhibited a â€Å"Rogerian† style of child rearing, that is, a style in which few conditions of worth were imposed on children and, instead, children were accepted for who they are and were allowed to explore the world freely. There were two such measures.One was a self-report of parents’ child-rearing styles, and the other was an observational measure in which researchers observed parents interacting with their children and coded whether the parents acted in a prototypic Rogerian manner. They two measures were combined into an overall inde x of Rogerian child rearing. In adolescence, the researchers obtained a measure of creativity. Teachers were asked to rate the degree to which the research participants, who were their students, approached tasks in an open-minded, creative manner.Since the researchers had measures on the same individuals at two points in time, they were able to determine the degree to which the childhood measure of parenting style predicted the adolescent measure of creativity. The finding strongly supported Rogers’ theory of personality development (Harrington et al. , 1987). Just as Rogers would have predicted, children whose parents treated them in a Rogerian style turned out to be adolescents who were judged as being more creative. Child rearing style was a statistically significant predictor of creativity.Importantly, this was true even when the researchers controlled for a measure of intelligence that also was obtained during childhood. It is not merely the case that intelligent childre n were treated in a Rogerian style and also were creative. Instead, even controlling for intelligence, parental child rearing predicted creativity. In evaluating the two theories, the results clearly support Rogers’ phenomenological perspective, as noted above. Children’s experiences of alternative parenting styles seem to have influenced a significant aspect of their personality and to have done to in exactly the manner Rogers would have anticipated.In contrast, the results conflict with the trait theory position that personality characteristics are largely inherited and that aspects of the environment that are shared by multiple siblings, such as parental child rearing style, exert little influence on personality characteristics later in life. Since the work of Harrington et al. (1987) was conducted a number of years ago, one might ask how trait theorists, in light of these results, could maintain their view that parental styles of child rearing exert little influenc e on personality. The results would seem to provide objective evidence against their theories.One possibility is that trait theories are focusing only on specific, narrow aspects of human personality, and that parental child rearing styles exert an influence on other aspects of personality that trait theorists have overlooked. Recall that, as described above, the core variables of trait theory are people’s average tendencies to exhibit general styles of emotion or behavior. It is noteworthy that none of these personality trait variables addresses people’s self-concept. Although trait theorists surely do recognize that people have self-concepts, they seem to have eliminated the notion of self-concept from the core of personality.Self-concept is not a â€Å"personality structure† in their view. This seems hard to defend, since people’s views of themselves are such a central feature of psychological experience. By focusing on overt styles of behavior, rather than the inner psychological life of the individual, including his or her views of self, trait theories may be missing an important aspect of human nature. The development of a stable conception of oneself and one’s personal qualities is a critical feature of personality, and it may be one that is shaped to a large degree by interactions between children and their parents.

This was a rare instance in which I wanted to quote directly fr om another source, in order to get the precisely correct definition on the term.To indicate that the material is taken directly from the textbook, I put the passage in quotation marks and included the page number in the book that contains the original material (p. 226). Note that you have to take these two steps even if you take only a few words from the other source. Even though it was only 7 words, Pervin and John wrote those words, not me, so they have to be in quotes. Otherwise, the material would be plagiarized. Any material that comes from another source and that appears in your paper has to be in quotation marks, and you must include the page number on the book or journal that contains the original material.In general, you should have very few passages of directly quoted material. The words in your paper should be yours, not somebody else’s. 2. This paragraph is a useful one for this paper assignment. Perhaps the most difficult part of the assignment is to figure out h ow specific, concrete research findings relate to the general, abstract ideas of the personality theories. You should make clear to the reader how the study that you review relates to the two theories. 3. When writing the paper, you should provide some information about the type of study your are reviewing, as in this paragraph, and then should review the results.

Power Term Paper Example | Topics and Well Written Essays - 1000 words

Power - Term Paper Example Individual viewMany people view power from a negative perspective while very few individuals view power from a positive perspective. According to Elizabeth Laneway, she claims that we are put off by power because we embrace fear and we think that we do not have the capacity to work with responsibilities associated with power. The famous phrase about power by Lord Action that, power corrupts but absolute power corrupts absolutely has made many individuals to view power as a practice associated with social ills to the community. The fear enacted from power makes many people to remain isolated making thing they can change that are within their capacity to remain unchanged. This is because we fear responsibilities that are associated with power and hence give a chance to other people to make decisions rather that getting involved with that power so as to solve problem surrounding us.Power is a commodity that is dormant in each and every individual until one decides to exploit the potenti al and put it into action. Every individual has got the capacity to assimilate others hence effecting changes in communities hence providing long term solutions to community problems.Philosophers and theologians view Philosophers and theologians have a different view about power. They have intensified their research in trying to determine the concept of power and trying to bring out the real explanation pertaining power. They consider power to be a neutral term being neither good nor bad until it is applied to human acts.

Give a history of the Catholic Church on the death penalty and note Research Paper - 3

Give a history of the Catholic Church on the death penalty and note how it has changed over time - Research Paper Example In the early stage, the catholic churches are considered to be the higher legal authorized body. During the middle ages, the people duly followed the pathway of churches. The Catholic Church is identified to follow capital punishment. However, presently, it has a strict negative statement about capital punishment. According to Catholic teaching, punishment is used against a crime with the aim of defending a society and in case of the failure of defending a society from such criminals, capital punishment should be used (Uelmen 355-356). The prime intention of the study is to reveal the role of the Roman Catholic churches towards providing judgment against a punishment. Apart from this, the study describes about the importance of churches for sentencing capital punishment. Contextually, the study will also reveal the transaction of the traditional Catholic Church in the present day context. The term capital punishment is accustomed and well known in the society. Capital punishment is also ascertained as death penalty in several countries. The law or the rule of death penalty was established during the period of 18th century B.C. The law of death penalty was introduced by Hammurabi, King of Babylon. Death penalty was introduced by King Hammurabi for different crimes and offences. Apart from this, death penalty was also followed during the 14th century by different legal bodies and churches. Besides that, Britain also established the law of sentencing death penalty as a punishment to those people who are committing any criminal offences. With the inspiration from Britain in providing the capital punishment, America also follows the tradition of capital punishment. It is ascertained that America having the highest records in sentencing punishment through death penalty. It has been affirmed that during the middle ages when British people entered America for shelter, Americ ans brought the practices of

Racial Violence - The Case of George Zimmerman Essay

Racial Violence - The Case of George Zimmerman - Essay Example Racial violence is not like other types of violence because its primary cause is based on beliefs of superiority and hatred of other individuals or groups who are destined to be inferior due to their ethnicity; and due to their physical features like skin color. Racial violence takes many forms. It can be as subtle as teasing or pushing and can be severe as murder, physical assault, and genocide (Browne-Marshall 15-18). This essay analyzes a recent racially charged issue—the case of George Zimmerman, a Hispanic guard who killed a young black man, Trayvon Martin, allegedly as an act of ‘self-defense’. This case is analyzed in terms of the causes and effects of racial violence. The Role of Race in Zimmerman’s Case Although racial violence is more obvious, other types of violence are similarly destructive. There is an increasing number of evidence that continuous harassment negatively affects the health of its victims. It inflicts psychological and physical pa in which is passed on to subsequent generations (Gruber 1573). Being constantly anxious or fearful because one is racially different and continuous harassment are root causes of poor self-worth and mental disorders. People who are subjected to racial violence usually accept or embrace an identity with the undesirable images they are assigned to. Resistance at times results in greater and more severe discrimination and violence (Bonilla-Silva 22). The belief that everyone is created in God’s image is hollow when the identity one embraces is that of a lowly, insignificant individual. The death of Trayvon Martin compelled Americans, once more, to confront the nation’s tragic history of racial violence. Nevertheless, possibly because the death of Martin evidently resembles the death of a huge number of young black men in the past and recent times, the debate over the issue seemed historically inclined.

Whistleblowers. The Process and Risks Assignment

Whistleblowers. The Process and Risks - Assignment Example Some of the recent examples of whistleblowers are Sherron Watkins of Enron, and Cyntha Cooper of WorldCom. They exposed or provided firsthand information on financial scandals. The case of Coleen Rowley of the FBI as a whistleblower was unique in the sense that the reporting incident was regarding lapses in the intelligence field a few weeks before September 11, 2001 terrorists attack. The Process of Whistle Blowing An employee who has some information about illegal activities of any nature pertaining to his or her organization and he or she chooses to bring that in public is known as a whistle blower. Whistle blowing is encouraged to bring honesty, equality, justice, and freedom of speech in society at large. It has many advantages such as it can protect health of consumers and employees. During 1920s, the harmful effects of asbestos in the manufacturing units were suppressed by company managment thus jeopardizing the health of employees. Employees feel more comfortable if they find it easy to raise their concerns within the organization. Risks Associated with the Whistleblower Whistleblowers carry certain risks such as alienation, face reprisals, or victimization at their workplace and likely to be more intensely supervised for their acts. They may be considered less loyal to their organization or employer for their act of blowing the whistle against the organization. Luque (2007) reports about one of the study of whistle-blowers in which 90% reported about emotional stress, anxiety and depression after their acts of whistle blowing. Around 54% of them reported harassment at their workplace and 10% were the cases of attempted suicide. Case Studies Sherron Watkins – Whistleblower of Enron The case of Sherron Watkins, the former corporate vice-president of Enron, is worth enumerating for the psychological trauma that she faced after her act of whistle blowing. In the month of August 2001, Sherron Watkins wrote a memo to the CEO of Enron that explained ho w the accounts of Enron present a distorted accounting numbers. On this, the CEO directed for an investigation through Enron's own law firm that did not do an honest job. Soon, the New York Times published a story about Enron's accounting jugglery. Thereafter, a congressional committee delved into the issue and started investigating the matter. Overnight, Watkins came into limelight and became a celebrated whistleblower that exposed Enron's accounting misreporting. This had a catastrophic effect on the company. Not only Enron was compelled to sack 4000 employees from its payroll but the very next day they filed Bankruptcy Code protection under chapter 11. Enron shares plummeted like a big log from the high of $90.75/share in August 2000 to the dismal $0.067/share recorded on Jan 13, 2002 (Luque, 2007). Watkins suffered more of a psychological pressure when she first acted as a whistle blower. She was isolated and made unnecessary for the company. Most of her partners began hating he r as because of her 4000 employees lost their jobs (Luque, 2007). Cynthia Cooper – Whistleblower of WorldCom Cynthia Cooper was working as vice president of internal audit at WorldCom. On her routine investigations, she found that certain expenses were being capitalized thus inflating the yearly earnings by several billions of dollars. More she investigated, the stranger the reactions she confronted with from some of her colleagues. She sought an explanation from the Chief Financial Officer of the company. On this, she was asked to stop the audit until the next quarter -- a date to begin her normal audit as per routine. However, she did not stop on this and organized a meeting with the company's auditor KPMG. Finally, it was found that earnings
