I did not buy this book,I read it online after coming across it in the most funny way.I was sitting jobless in office having shut out myself to the Gulti banter of my colleagues. And was surfing the net,reading stuff on Google Reader.In a funny picture,there was a note scribbled inside some wretched instalment of the Twilight series,urging the readers to please not read it and go look for other books in the huge sea of literature.One name mentioned there was Alaska by John Green.The title is Looking for Alaska btw.So I decided to give it a look,and directly got the pdf on the net. So here it goes The book got me reeling,and made me type this. This is rarer than the appearance of the Haley’s Comet .But something about this book,touched my heart deep down.It is not a literary masterpiece,deemed even offensive by some(read it on wiki),it isn’t like I have the ultimate authority on literary masterpieces.But the writing is fluid,very conversant,almost mundane yet very engaging.

Looking Back...

... LOOKING BACK……… Surrounded by four grey walls, I lay here on my concrete bed and I think …….Why? Did he deserve it? Am I really the monster that I was portrayed to be? My name is Katherine Pierce. I am 25 years old and I have been sentenced to 10 years imprisonment for the murder of the man I once called …..my dad. The birth of any child into a family is a joyous occasion. And yes, my entry into this world was a dream come true for my parents. As a baby, I have fond memories of being cradled by the gentle touch of my mother’s arms, always showered with love and affection. I vaguely remember sharing this relationship with my dad for he was seldom at home. But on those rare occasions, when we were together as a family, it was never the utopian dream I hoped for. What remains vivid in my memory are those numerous occasions, when he would come home from work and rant and rave at my mom for the most trivial reasons. She was the constant target for this verbal abuse and never did she show any signs of retaliation. My father was accorded the utmost respect by both of us and he took advantage of this as he knew that we were totally dependent on him as he was the sole breadwinner. There was no way that anyone could reason with him when he was in this frame of mind. What baffled me the most was the façade he put on when we were around friends and family. He appeared to be the perfect gentleman …..always so kind, energetic, high spirited, full of laughter and generally fun to...

Looking for Patterns

...Looking for Patterns Blaise Pascal was a French mathematician who lived during the 17th century. He is credited with creating a mechanical calculator, and he influenced the development of probability theory, economics, programming, and geometry. A pattern of numbers in the form of a triangle was named after him, although the pattern was known by other, ancient civilizations. The triangle demonstrates the inherent order of numbers and math. The exercises below challenge you to find and define patterns. Often being a good problem solver relies on one’s ability to recognize patterns and changes in patterns. • How many triangles can you find in this picture? 27 • Develop a rule to describe the number of circles in the figures below. Find the number of circles in the 20th figure, and indicate the reasoning.

Looking Up and Looking Around

...Reading 1.3  Jackall, R. (1988) Chapter 4, ‘Looking Up and Looking Around’, in Moral Mazes, Oxford University Press, NY. Abstract In the early sections of “Looking Up and Looking Around” Jackall seeks to explain the reasons behind inadequate decision making processes and ability. The circumstances and environments that cultivate ‘decision-making paralysis’ and a lack of individual decision making ability are explained. Numerous examples and reasons are outlined to communicate a manager’s fear of failure, reluctance to make decisions and inability to make effective decisions when required at all hierarchical levels. If a decision must be made, particularly for an unexpected situation or problem, there is a tendency to look up, at superior’s intents and desires, and look around, at the general consensus of peers, before making any decisions. Jackall also explains managerial short term focus, the corporate culture of self interest and the reasons for each. In particular, he explains the manager’s interest in their progression and preference for short term, self promoting, often political, decisions over rational decisions that benefit the organisation in the long term. These passages show that personal ambition prevents good, rational decisions being made. Jackall also shows how this extends to the blaming of others and changing jobs in order to avoid being accountable for the consequences of previous decisions or strategies that enabled individual corporate progression. In...

Insider Looking in

...The Outsider Looking in: An American in Japan SNHU Communication between people is always unique as no two people are alike and this difference is even greater when we communicate with people outside our own culture or country. As humans we generally strive for the same basic needs in life; food, shelter, companionship, but beyond those points we can find it difficult to communicate more complex ideas with those of different backgrounds. Once we are aware of another person’s differences and we can understand their point of view we increase the chances of better comprehension, fewer misunderstandings, and a mutual respect for one another (Academia). For this discussion we will examine the differences between a high-context culture, Japan, and a low-context culture, the United States, and how people from each are able to work on communication despite the language and culture barriers. I was able to speak with Maiko Suzuki, a colleague of my wife, who is from Japan and has lived in the United States since 2010 working in a PhD program as well as a research lab in Boston. From the start I knew she had trouble understanding the research I was trying to do but we were able to overcome this in time. Like most foreigners, even those who have a firm grasp on the English language, they still struggle to make communication that is native to the United States due to the cultural differences. From that point Maiko was able to describe how she has been able to overcome the......

...  Looking In I agree that I can read other people emotions. As a leader in the military this skill is a must. You have to have the pulse of your unit, you have to be able to see that your soldier(s) are having a problem. I agree that I can easily perceive and expression my emotions, however there is always room for improvement. I will continue to “read” people and try to assist them in any way I can. We all need help at one time or another even if it’s just talking to someone to get something off ones chest. I will start working on my lack of patience sometimes. I will stop, assess the situation and make a rational decision. I do from time to time have a lack of patience and this is an area that I will continue to seek self-improvement on. This self assessment will assist me in the work place because it shows me I have the ability to perceiving and identifying other emotions. By having this ability it will allow me to be a better member of the team. If I have a co-worker that is easily annoyed by something, I will pick up on that and I can adjust my approach on working with him/her to avoid conflicts. By implementing this assessment into my work place it will also let me know who I can express emotion too and know how certain people will respond to a show of emotions. I can also use this tool to understand how I will react in certain situations and how I can respond to conflict or adversity. Interpersonal communication is the process of sending and receiving......

...go after what they want in life, a good job to support themselves and a stable environment to live in where it is safe. I really enjoyed this site learning experience and I also asked the supervisor to let me know if there were any permanent part time job openings. I enjoyed getting to know and especially watching them grow into responsible youths. Tutoring was a easy job, but I enjoyed the time spent with each and every one of them and getting to know their cultural backgrounds better. I think that my teamwork and problem solving skills has been at its best since working here and I will truly miss each and every youth that I tutored. This has been an eye-opening experience because the youth all came from true poverty situations. Looking at them makes all my problems seen like nothing compared to the lives they have lived. I have a new outlook on life and how hard things can be. These kids have gone through much more in their lives than I could ever begin to understand. To see them succeed is the best feeling in the world and I wish them all the best of luck. I would want to get back there some day to help and tutor again and maybe even become a teacher there.

Just Looking

...According to Theorem 10.7, we know 3 √ the solutions to tan(θ) = 3 must, therefore, have a reference angle of π . Our next task is 3 to determine in which quadrants the solutions to this equation lie. Since tangent is defined y as the ratio x of points (x, y) on the Unit Circle with x = 0, tangent is positive when x and y have the same sign (i.e., when they are both positive or both negative.) This happens in Quadrants I and III. In Quadrant I, we get the solutions: θ = π + 2πk for integers k, and for 3 Quadrant III, we get θ = 4π + 2πk for integers k. While these descriptions of the solutions 3 are correct, they can be combined into one list as θ = π + πk for integers k. The latter form 3 of the solution is best understood looking at the geometry of the situation in the diagram below.4 4 See Example 10.2.5 number 3 in Section 10.2 for another example of this kind of simplification of the solution. 748 Foundations of Trigonometry y 1 y 1 π π 3 π 3 x 1 x 1 π 3 3. From the table of common values, we see that π has a cotangent of 1, which means the 4 solutions to cot(θ) = −1 have a reference angle of π . To find the quadrants in which our 4 solutions lie, we note that cot(θ) = x for a point (x, y) on the Unit Circle where y = 0. If y cot(θ) is negative, then x and y must have different signs (i.e., one positive and one negative.) Hence, our solutions lie in Quadrants II and IV. Our Quadrant II solution is θ = 3π +......

Looking for Work

...Gary Soto’s “Looking for Work” One July, while killing ants on the kitchen sink with a rolled newspaper, I had a nine-year-old’s vision of wealth that would save us from ourselves. For weeks I had drunk Kool-Aid and watched morning reruns of Father Knows Best, whose family was so uncomplicated in its routine that I very much wanted to imitate it. The first step was to get my brother and sister to wear shoes at dinner. “Come on, Rick – come on, Deb,” I whined. But Rick mimicked me and the same day that I asked him to wear shoes he came to the diner table in only his swim trunks. My mother didn’t notice, nor did my sister, as we sat to eat our beans and tortillas in the stifling heat of our kitchen. We all gleamed like cellophane, wiping the sweat from our brows with the backs of our hands as we talked about the day: Frankie our neighbor was beat up by Faustino; the swimming pool at the playground would be closed for a day because the pump was broken. Such was our life. So that morning, while doing-in the train of ants which arrived each day, I decided to become wealthy, and right away! After downing a bowl of cereal, I took a rake from the garage and started up the block to look for work. We lived on an ordinary block of mostly working class people: warehousemen, egg candlers, welders, mechanics, and a union plumber. And there were many retired people who kept their lawns green and the gutters uncluttered of the chewing gum wrappers we dropped as we rode by......

Looking at Luxury

...Looking at luxury: consuming luxury fashion in global cities Professor Louise Crewe, University of Nottingham, UK Dr. Amber Martin, Queen Mary University of London, UK 1: Introduction This chapter explores the growth and transformation of the global luxury fashion market focusing specifically on the flagship stores of the largest global luxury fashion organisations.[1] The conceptual basis of the chapter lies in recent debates about global economic austerity and the future of consumption under conditions of precarity. The chapter focuses on the remarkable resilience of the luxury market in the face of global recession and the slow-down in consumer spending. Luxury consumption and passionate investment are argued to provide one means through which the more deleterious effects of the over-consumption of cheap, throwaway, fast fashion can be effaced. The arguments made in the chapter are both theoretically and empirically significant. Firstly, luxury fashion is empirically an important but neglected area of scholarship and one with a pronounced Geography that requires scrutiny. The luxury fashion market is significant not only in terms of its value but also in terms of its rate of growth which has significantly outpaced that of other consumer goods categories over recent decades. The rate of growth has been driven by a variety of factors, including growing concerns over the economic, environmental and social impacts of throwaway fashion, a desire for more responsible......

Abstract Jackall Looking Up and Looking Around

...A general decision making criterion involves several factors. What this journal focuses on is the influence of others’ decisions on one’s own, namely, the act of “looking up and looking around”. In any given situation it is human nature to first “look up”- that is, see what a more knowledgeable person (such as the boss) is doing, and then take a decision as to how one would act. The second option is to “look around”- that is, see what one’s colleagues and peer are doing and follow suit. The author also writes on how “decision-making paralysis” hits everyone from middle range managers to even the top managers and CEO. When presented with a problem, the mind goes blank and the person the question is directed to is stuck in a rut. Either they don’t know how to solve the problem and are looking for someone else to take the burden; or they are apprehensive to make any decisions because they might fail. Many managers suffer severe anxiety that their incapability might be found out. That’s why senior managers are more preferred as they have a greater hold over making a decision based on their gut instinct. Decision-making is not only the manager’s headache, it also depends on the structure and progress of an organization. Many managers are pushed to make decisions within a short time, and that too decisions based on information passed on from the junior levels. On several occasions the information may not be particularly correct and that would result in a decision made on unreal......

Looking in Religion

...Looking at Religion Living Religions Marsha D. Ferron Dr. Lyndol Loyd Religion, it can be defined in many different ways, such as a service where people go to and listen to a person speak from a book (called a bible in many religions), or the act of kneeling and praying to a God or higher being. Or it could be a person’s choice how to live their life. Religion is described as a service or worship of God or supernatural, commitment or devotion to religious faith or observance or a personal set or institutionalized system of religious attitudes, beliefs and practices (Merriam-webster.com). As I travel earth I have visited many countries and believe religion takes on many different forms. In some countries like Israel, the practiced religion is Judaism which is also a way of life for the Israelites and often is referred to as Jewish. They believe in one God. The Jews read, study and teach the Hebrew bible to their children and each other. Their way of life has been passed down from generation to generation. This can be found in the old testament of the bible, when God spoke to Moses and told him that He will free his people from Egypt and take them to the promise land (Israel). God also gave Moses the Ten Commandments. They are the laws that God created for Moses, the children of Israel and for future generations to live by. Another religion I observed was Islam; a person of this faith is called Muslim. The Muslims also believe in one God and they read the......
