Racial Constructs - Essay Example y of individuals is the cultural issues and environment as in the article, race concepts in medicine, but all individuals if subjected to the same conditions and environment will think and act the same despite the race. On the contrary, it is true to some extent that according to Jethro’s message with are right as per the movie district nine. Forcibly, Van der Merwe struggles to relocate the aliens who had come in a ship and was settling in a section of South Africa. Since humans could not operate the weapons that the aliens had, the growth of a claw in the place of a hand by van, propelled him to be a central operator of both the Nigerian gangsters and Security Company. The Nigerian gangs were exploiting the aliens by selling them cat foods. However, the above to some extent portrays the evidence of the fact that whites are always right. This is so because everyone was afraid to relocate the aliens and the only torch bearer was a fan, whom manages to maneuver through to become a hero in deals and designs of relocating the aliens who were rejected by the residents. With his racial complexion of white, Van der Merwe seams to be successful, and at this point is when there is approving of the t erm whites are right. Here, the hero tactically finds an idea that the only way to operate the alien’s weapons is by growing a lobster claw in the place of his hand. With the above claws, he manages to be a security company and at the same time, he operates the Nigerian gangster ideas by exploiting the aliens from the cat food being sold to them. All the above was for the efforts of relocating the aliens, though it was not an easy task to relocate them. Having put that across, the fact remains that Van der Merwe used his brains to explore the aliens by not only growing the claws but also incorporating those aliens who proved to be intelligent and those that had human emotions. It is evident according to the movie district nine that the aliens in the movie are of the

The Value of Life Essay Example for Free

The Value of Life Essay The value of life is a heavy and controversial thought in many ways it is necessary to put a price on death but in others it seems un-just or not right to the grieving family and friends who has just lost someone. There cannot be a price on life that is at all fair to the lost ones family but the government feels that they can give one. If there must be a dollar amount on life how do you determine what it is there are many facts and opinions on how to figure that out as well, but does any dollar amount bring back the lost man or woman; of course not. People say that a person’s after life amount should be looked at in an equal way to the amount of money they earned whilst still living. There family should receive enough money so that they can continue living as if there loss was still there. But if that was fair, a homeless person or someone who hasn’t made a good amount of money over life time should be worth less than an average person or a person with a higher life standard. Every human should be equal to no matter the amount of money that you have collected. A stronger belief is that every persons loved ones should be given a certain amount of money such as $500,000. More people believe that that is the most fair and just option. But of course we want the best for our loved ones and $500,000 does not cover those expenses. But if any amount above that were given people would try to take advantage of it. Faking deaths and murdering family members just for the amount of money that is given.

Lets Talk About Denial: not a river in Egypt :: essays research papers

Denial, the topic for this week’s discussion, is unfortunately not a river in Jordan. While not a river, it is a characteristic that at times seems to be as resistant to change as the most torrent watercourse. Denial has been described as many things in many ways by many people and still I find the Webster’s Dictionary definition of denial to be the most meaningful and accurate: â€Å"an assertion that an allegation is false†¦disbelief in the existence or reality of a thing†¦self-denial†¦[and] the reduction of anxiety by the unconscious exclusion from the mind of intolerable thoughts, feelings, or facts† (1977).   Ã‚  Ã‚  Ã‚  Ã‚  The readings and following class discussion illuminated just how varied and vast denial can manifest itself, especially with alcoholics and addicts. The discussion concluded that denial may be noticeable in the form of 1) an individual not being able to accept what is in front of him; 2) a coping mechanism to deal with facts as presented; or 3) the inability to see consequences of one’s behavior. Also based on the class discussion, things a counselor can look for to discern if a person is in denial are 1) if they consistently miss or avoid scheduled sessions, or while in sessions they continually change the subject; 2) if clients appear to reject logic or reason; 3) clients demonstrate incongruence, that is their non-verbal expression and actions are inconsistent with what they say; and 4) clients demonstrate the various defense mechanisms associated with alcoholism, addiction, and denial.   Ã‚  Ã‚  Ã‚  Ã‚  These defense mechanisms can be in the form of projection, (â€Å"I don’t have a problem –you have a problem.†) rationalization, (â€Å"It helps me relax/concentrate/forget† or â€Å"I’ll stop as soon as the pressure lets up†) justification, (â€Å"Everyone I know does it†) suppression or repression, (forcing down memories of using behavior and negative consequences as a result of that use and behavior) and one that sometimes gets overlooked, geographic escapes (my life is unmanageable – but it’ll get better if I move to another place.)   Ã‚  Ã‚  Ã‚  Ã‚  The text also offered some useful information in understanding the phenomenon of denial. On page 30 of the text Assessment of Addictive Behavior, Tarter, Alterman, & Edwards (1985); Tarter & Edwards (1986); Tarter, Hegedus, Goldstein Shelly, & Alterman (1984) suggest that â€Å"†¦neuropsychological deficits among alcoholics, particularly deficits in accurately perceiving internal cues of physiological arousal and emotion and in appraising the significance of environmental events, may underlie what has been described as ‘alcoholic denial’ † (cited in Donovan & Marlatt 1998).

Going Against Nature with T.C. Boyle

Jessica Arroyo English 116 11 April 2012 Life is hard. There are two things we need to succeed in life. We need to understand that nature is a key player in life, and that it has a greater power over us than we do it. We cannot control nature, nor can we impact what it has in store for us. If nature, such as the weather, decides there’s going to be a storm this weekend, well the best we can do is prepare for it. If nature creates us in one mode, who are we to go against it and try to change our species? If nature decides it’s going to slam a commit into the earth, we are helpless in the matter.Going against nature, or even questioning its methods, has its consequences and the characters of the short stories written by T. C. Boyle seem to know this all too well. Nature is a greater power who demands great respect. It is not a choice in matter, but rather a forced way of life that we have no means to alter, which Boyle convincingly conveys through his stories. In the stor y â€Å"The Swift Passage of Animals†, T. C. Boyle takes us on a â€Å"big adventure† (91) in which a new relationship is intended to flourish by a romantic weekend getaway.The nature of the male, Zach, is to impress the young recently divorced woman, Ontario. Though they are already dating, he is still courting her in hopes to further impress her by taking her to â€Å"hike the trails and cross-country ski†¦ and then sit at the bar at the lodge till it was time to go to bed†(84), by sharing the experiences with the greatest thing they have in common, their love for nature. Of course, there is more in it for Zach than just enjoying the beauty nature has, he intends on fulfilling the â€Å"unspoken promise percolating beneath the simple monosyllable of her assent—going to bed† (84).Zach is using her love of nature to his fullest advantage. Nature is not something to be taken advantage of, as it is not something to be questioned or controlled. Z ach, being the dominate â€Å"risk-taker† (79) that he believes himself to be is about to get a whole new taste of what nature has to offer when take advantage of for personal gain. Though Zach claims that the main reason for their trip is to explore and enjoy their common interest of nature at the Big Timber Lodge it is just a cover for what he really has in mind, which is going to bed with Ontario. T. C.Boyle’s diction throughout the beginning of the story foreshadows this â€Å"unspoken† (84) intention of Zach by placing details such as â€Å"the soft sexy scratch of [her voice] shot from his eardrums right to his crotch† (80), and the reference of her sweater with the â€Å"reindeer prancing across her breasts† (81), he foreshadows the consequences of these provoking thoughts by directly following them with the dangers of the â€Å"sleet† â€Å"dark† (80) road they were on. In showing his dominance and risk taking skills, Zach cho oses not to prepare in case they get caught in a storm on the way to the Lodge.He also presses nature even further by choosing to take the back road even though â€Å"there was a winter storm watch out of the Southern Sierras†¦and he knew that [it] would be closed as soon as the first snow hit† (74). All he could think about was getting there as fast as he could. â€Å"He was always in a hurry. Especially tonight. Especially with her† (74). Zach experiences his â€Å"first prick of worry† (81) when he spots a sign that said â€Å"Cars required with Chains† (81). Perversely† (95) nature enhances his worries by letting the snow paint the road with such intensity it was â€Å"as if some cosmic hand had swept on ahead with a two-lane paintbrush† (81). Despite the skidding of the tires and the snow â€Å"coming down as if it wasn’t going to stop till May† (88), Ontario maintains full confidence in Zach. â€Å"She wasn’t staring out the windshield into the white fury of the headlights, but watching him as if they were cruising down the Coast Highway under a ripe delicate sun† (83).But even with the confidence of his potential mate, his risk taking skills, and attitude nature still manages to turn things around on him when the car skids into a boulder and lands itself in â€Å"a glistening white ditch that undulated gracefully away from the hidden surface of the road† (85). Zach is now completely alone in the nature with Ontario, â€Å"which was where he really and truly wanted to be† (85). However, it is now that all of his unpreparedness becomes apparent. â€Å"He didn’t have a shovel in the truck—no shovel, and no chains† (86).No â€Å"knife† or â€Å"hatchet†, or â€Å"anything to cut with† (87). Nothing of any use to assist them in getting the tires up and out of the ditch. All of their feeble attempts merely gave â€Å"the rear whee ls a moment’s purchase† which just resulted in â€Å"[shoving] the front end in deeper† (88). Nature successfully pulls this egotistical, risk taking, prideful, dominant male down â€Å"to feel less a risk taker and more a fool, callow, rash, without foresight of calculation, the sort of blighted ndividual whose genetic infirmities get swallowed up in the food chain before he can reproduce and pass them on to vitiate the species† (86). As nature pulls Zach further and further down, deepening his misery by torrential snow and all the worries that come with leaving your car out in the middle of the wilderness (such as if â€Å"the yahoos come out and strip it† (92) ) in an attempt to hike to the Big Timber Lodge which was still a long â€Å"thirteen miles† (93) away, Ontario is â€Å"inordinately cheerful† (91).But â€Å"given how miserable [Zach] was† (91) because of the crash, he was able to pull the optimistic outlook of Ontari o down to his pessimistic level. By the end of their hike, Zach finds himself grouped into â€Å"the unlucky and unprepared† (95) people which nature tackles with full force. His trip was ruined, as well as his time with Ontario. When they finally reach the lodge, after being rescued from the cold by â€Å"the man in the goggles†(96) on a â€Å"snowmobile† (96), Ontario corrects Zachs request of a room to â€Å"two rooms† (98). In â€Å"Dogology† T. C.Boyle introduces us to Cynthia, or â€Å"C. f. , Captial C, lowercase f† (44) as she prefers to be called. She is a young woman who has finished grad school and attempting to â€Å"challenge† (35) the misconceptions people have about dogs. The world views dogs as â€Å"beneath them†¦ common, pedestrian, no more exotic than the housefly or the Norway rat† (35). C. f. was obsessed with changing the worlds view of dogs despite the fact that â€Å"the graduate committee rejected her thesis† (35). Humans have domesticated dogs. This results in two types of dogs: the wild and the domesticated.Cynthia challenges the methods of nature, by trying to change herself into a member of the pack. She committed herself to doing things as the pack would, â€Å"made a point of wearing the same things continuously for weeks on end†¦ in the expectation that her scent would invest them, and the scent of the pack too† (40). She â€Å"[hoped] to gain their confidence† (40) by smelling like them, running with them â€Å"reminding herself to always keep her head down and go quadrupedal whenever possible† (35) this was how she was going to â€Å"hear, smell and see as the dogs did† (35).Nature did not intend for Cynthia to take on the life of the dog. She was born human, and yet â€Å"what she was doing, or attempting to do, was nothing short of reordering her senses so that she could think like a dog and interpret the whole world— not just the human world—as dogs did† (35). Cynthia is exposed to the consequences of challenging nature by converting yourself to a different species of the world. Though married, Cynthia commits her days to accomplishing â€Å"the rhythm of dogdom† (40), ignoring the needs and the wants of her husband.She throws her â€Å"neighborhood into an uproar† (41) to the point where â€Å"they’re going to have her committed† (51). Her husband â€Å"locked her out† (50) of the house, leaving her to be with the dogs after a confrontation in which â€Å"he’d kicked her† (49) out of the frustration of her â€Å"research†(49) which he plainly saw as â€Å"bullshit† (49). â€Å"He wanted her back home, back in the den, and that was his right† (49), however Cynthia had other ambitions. Truly, she was accomplished being â€Å"left alone†(49) to enjoy â€Å"the unalloyed sweetness in life† where â€Å" the sun blessed† her body as she lay â€Å"streched out† among the pack.However, to the average citizen it may seem all a bit too costly to sacrifice the lives we live and relationships we have all for an understanding of something so â€Å"common† (35). In â€Å"Chicxulub† we are faced with the worst scenario a parent can imagine; a late night phone call, when we least expect it, stating â€Å"there has been an accident† (135) involving our own daughter, or in this story their daughter, â€Å"Madeline Biehn of 1337 Laurel Drive† (135).We are rushed through a flury of emotions while paralleling the catastrophic events of â€Å"Tunguska† (133) and â€Å"Chicxulub† (136), a â€Å"meteor† (133) and â€Å"asteroid† (136) that had impact with the Earth with such force that they were able to flatten â€Å"seven hundred square miles of Siberian forest† (133) and make â€Å"at least seventy-five percent of all know n species extinguished† (136). The most recent of the two, â€Å"Tunguska† (133) was â€Å"nearly a hundred years ago† (133).No one was expecting it, as no one expects a phone call in the middle of the night saying your child has been in a car accident. It seems nature has an awful need to demonstrate its authority every now and again, reminding us â€Å"that we, and all our works and worries and attachments, are so utterly inconsequential† (139). The chances of these catastrophic events are rare; they are about as likely as â€Å"dying in an auto accident in the next ten months†, however they are not unheard of. There is nothing we can do if one of these events were to take place in our lifetime.It doesn’t matter if you spend your life preparing for such a catastrophic event, such as the most recent dooms day preparers, or you buy your daughter â€Å"a Honda Civic, the safest thing on four wheels† (134). If nature has a plan it will e nact and follow through with its intentions. In fact the narrator clearly states his â€Å"point. You’d better get down on your knees and pray to your gods because each year this big spinning globe we ride intersects the orbits of some twenty million asteroids† (134). Sometimes, nature â€Å"perversely† (95) likes to hand out wake up calls.We find out after â€Å"the slow striptease of death† (142) as â€Å"the sheet draws back† (142) from the gurney where the supposed dead Madeline is to be, that their â€Å"daughter is not in the hospital† (143). Their daughter is exactly where she is supposed to be â€Å"asleep in her room† (143). It was a mistaken identity because Madeline â€Å"[loaned] her ID to her second-best friend, Kristi Cherwin† (143). The narrator of the story, â€Å"rushing still with the euphoria† realizes that this is not his daughter, and in fact not the â€Å"Chicxulub† of his lifetime.However he is left with a renewed perspective that â€Å"the rock is coming, the new Chicxulub, hurtling through the dark and the cold to remake our fate† (144). So it is through the stories that we have a renewed sense that nature is much more than a companion in life. Much more than just the flowers, and trees we pass by as we are â€Å"cruising down the Coast Highway under a ripe delicate sun† (83), much more powerful than our tactics of prevention such as our â€Å"Honda Civic† (134), or our will to undue to the simplification of our domesticated house pets.Nature has created the ways that we live in today. We are merely the players on its game board, â€Å"inconsequential† (139), insignificant. Nature does not bend to our will, but rather, we will bend to its will. Otherwise, we will be subjected to the wrath and fury of mother-nature itself.Works Cited Boyle, T. C. Tooth and Claw. New York: Viking, 2006. Blio. com. Blio. 2006. Web. 11 April. 2012.

Bell Hooks Biography

Bell Hooks take on booty:By:Course:Professor:Date: Question 1 Bell Hooks is an acclaimed intellectual who is known for her insight and tough analysis on the black culture. In her life she has earned many titles; the contemporary feminist, cultural critic, social activist, cultural critic, artist, writer and most outstandingly pussy to booty analyst. This an alias she earned from her popular book who's pussy is this? She was born in a small segregated black community in Hopkinsville town in Kentucky in 25th September 1958. The economic and social settings were not one she could boast about as the community it was poverty ridden and the source of income was just by working for low pay at construction sites or other low paying joints. Born by Veodis Watkins and Rosa Bell Watkins, Her real name is Gloria Jean Watkins but she chose the name Bell Hooks as a tribute to her grandmother and great grandmother. She earned a scholarship to Stanford University where she did her BA, later she went for masters at University of Wisconsin in Madison and finally University of California for her PhD. In 2014 she launched the bell hooks institute at Berea College situated in Berea, Kentucky. Question 2 Apart from giving her views in her books and popular website, she does her critic and gives further insights on black stories and popular cultures in television shows, newspaper columns and lecture talks with students in universities across the country. She has written over 30 books and the most popular titles are; Aint I a woman written in 1981, this books dissects the black culture and pays critical attention to the black woman. It studies what she does and gives theories to the reasons behind her action. Her theories are believed to hold water and make a lot sense as she gives explicit examples from the Kentucky community she grew in. In 1984 she wrote feminist theory which seemed like a sequel to her previous book. Here she gave more insights and explained how the black woman is marketing herself as an effort to level her reputation with white women by advertising herself in a different way; showcasing her booty. All about love was another best selling title written in the 2000, its subtitle was; new vision. Many young blacks have a liking for it as it holds connection to their daily love life; the book explains the theory of why teenagers think of falling in love at a tender age. It is an analogy of the teenagers having a feeling that their parents or the society doesn't give them enough love and attention and they tend to supplement the love with romantic affairs. In 2004 she wrote We real cool explained the black man's culture and perception of masculinity. Her latest piece that has reader's attention is whose pussy is this; it is trending as it explains the culture and general perception of booty. Question 3 The bottom line of all her books and lectures is to educate the audience that not all they and perceive about the booty is true. Before the audience; which is mostly the youth make a decision to widen her hips or enlarge her booty she should first have a critical analysis and the implications. Her view is that black female choice to resort to booty enhancement was out of desperation to be noticed and somewhat respected like the white females; that was at the end of racism period in the 1980. She believes that youths are attached to it as they see it to represent the new pop culture, one where the booty is perceived as a sexual liberator. This claims that is backed up by media evidence as females that have big booty are mostly if not the ones that always appear on television commercials and Hooks sees is deception. The central focus in females has shifted from the vagina to her booty as its visibility is a marketing advantage. Hooks is particularly saddened by the booty highlight on kids' clothes as it will make them grow in the deceptive theory that the only way to get noticed is by highlighting the attention on the booty, she says it's a destructive direction we are pointing the children to. Question 4 I totally agree with her theories because the booty has moved from a liberator of sexuality to portraying the egoistic nature of a woman. It is very deceptive as women with big booty think that they have a natural advantage over other women, they believe that they can dictate the male that can posses the booty according to the males financial status. This trend also increases the HIV transmission rate youths as they engage in anal sex under the misconception that anal sex does not transmit HIV.

How To Learn Chemistry Fast

How To Learn Chemistry Fast The first step in learning chemistry fast is to determine exactly how long you have to learn chemistry. Youll need a lot more discipline to learn chemistry in a day compared with a week or a month. Also, keep in mind you wont have great retention if you cram chemistry in a day or a week. Ideally, you want a month or longer to master any course. If you do end up cramming chemistry, expect to review the material if you need to apply it to a higher level chemistry course or remember it for a test further down the road. A Word About Chemistry Lab If you can do lab work, thats fantastic, because the hands-on learning will reinforce the concepts. However, labs take time, so most likely youll miss this segment. Keep in mind labs are required for some situations. For example, you have to document lab work for AP chemistry and many online courses. If you are doing labs, check how long they take to perform before getting starting. Some labs take less than an hour start-to-finish, while others might take hours, days or weeks. Pick short exercises, whenever possible. Supplement book learning with videos, which are readily available online. Gather Your Materials You can use any chemistry textbook, but some are better than others for fast learning. You could use an AP Chemistry book or Kaplan Study Guide or a similar book. These are high quality, time-tested reviews that cover everything. Avoid dumbed-down books because youll get the illusion that you learned chemistry, but wont master the topic. Make a Plan Dont be haphazard and dive in, expecting success in the end! Make a plan, record your progress and stick to it. Heres how: Divide your time. If you have a book, figure out how many chapters youre going to cover and how much time you have. For example, you may study and learn three chapters a day. It may be a chapter an hour. Whatever it is, write it out so you can track your progress.Get started! Check off what you accomplish. Maybe reward yourself after pre-determined points. You know better than anyone else what it will take to get you to get the job done. It may be self-bribes. It may be fear of an impending deadline. Find what works for you and apply it.If you fall behind, try to catch up right away. You might not be able to double your work, but its easier to catch up as fast as possible rather than have the studying snowball out of control.Support your study with healthy habits. Make sure you get some sleep, even if its in the form of naps. You need sleep to process new information. Try to eat nutritious food. Get some exercise. Take walks or work out during breaks. Its important to switch gears ev ery so often and get your mind off chemistry. It may feel like wasted time, but its not. Youll learn more quickly if you take brief breaks than if you study, study, study. However, dont let yourself get sidetracked where you dont get back to chemistry. Set and keep limits regarding time away from your learning. Helpful Tips Try to review prior material. Even if its just a quick review, planning a set amount of time to go over old material will help you retain it.Work through problems. At the very least, make sure you can work example problems if you have time (days or weeks instead of hours), work problems. Working problems is the best way to learn how to apply the concepts truly.Take notes. Writing down important points helps you learn the information.Recruit a study buddy. A partner can help keep you motivated, plus you can offer each other support and put your heads together when you encounter hard problems or challenging concepts.

The Difference Between Molality and Molarity

The Difference Between Molality and Molarity If you pick up a stock solution from a shelf in the lab and its 0.1 m HCl, do you know if thats a 0.1 molal solution or a 0.1 molar solution, or if there is even a difference? Understanding  molality and  molarity is important in chemistry because these units are among the most commonly used to describe solution concentration. What m and M Mean in Chemistry Both m and M are units of the concentration of a chemical solution. The lowercase m indicates molality, which is calculated using moles of solute per kilograms of solvent. A solution using these units is called a molal solution (e.g., 0.1 m NaOH is a 0.1 molal solution of sodium hydroxide). Uppercase M is molarity, which is moles of solute per liter of solution (not solvent). A solution using this unit is termed  a molar solution (e.g., 0.1 M NaCl is a 0.1 molar solution of sodium chloride). Formulas for Molality and Molarity Molality (m) moles solute / kilograms solventThe units of molality are mol/kg. Molarity (M) moles solute / liters solutionThe units of molarity are mol/L. When m and M Are Almost the Same If your solvent is water at room temperature, m and M can be roughly the same, so if an exact concentration doesnt matter, you can use either solution. The values are closest to each other when the amount of solute is small because molality is for kilograms of solvent, while molarity takes into account the volume of the entire solution. So, if the solute takes up a lot of volume in a solution, m and M wont be as comparable. This brings up a common mistake people make when preparing molar solutions. Its important to dilute a molar solution to the correct volume rather than add a volume of solvent. For example, if youre making 1 liter of a 1 M NaCl solution, you would first measure one mole of salt, add it to a beaker or volumetric flask, and then dilute the salt with water to reach the 1-liter mark. It is incorrect to mix one mole of salt and one liter of water. Molality and molarity are not interchangeable at high solute concentrations, in situations where the temperature changes, or when the solvent is not water. When to Use One Over the Other Molarity is more common because most solutions are made by measuring solutes by mass and then diluting a solution to the desired concentration with a liquid solvent. For typical lab use, its easy to make and use a molar concentration. Use molarity for dilute aqueous solutions at a constant temperature. Molality is used when the solute and solvent interact with each other, when the temperature of the solution will change, when the solution is concentrated, or for a nonaqueous solution. You would also use molality rather than molarity when youre calculating boiling point, boiling point elevation, melting point, or freezing point depression or working with other colligative properties of matter. Learn More Now that you understand what molarity and molality are, learn how to calculate them and how to use concentration to determine mass, moles, or volume of the components of a solution.

Social contract theory Essay Example | Topics and Well Written Essays - 250 words

Social contract theory - Essay Example This means the citizens have political powers unless they decide to transfer the power to the government. The past philosophers agreed that the government originated from the people’s contract in the society. They believed that people pledge loyalty and compliance with the government so that it protects them and their belongings in return (Dye & Schubert 29). There are various aspects of the American social contract highlighted in the Preamble and declaration. The county’s social contract is derived from the preamble that states that people have to collaborate with government to promote justice and protection of individuals’ liberty. This means that the main aspects of the country’s social aspects reflected in the preamble are the partnership between the people and the government, and the people’s freedom. The Declaration also serves as the constitutional foundation of the American social contact. One of the aspects of the country’s social contract in the Declaration is the commitment to people’s natural rights. Pursuit to happiness was another aspect of the Declaration reflected in the county’s social contact (Billias

Marketing and globalisation - Essay Example However, such of re-appropriation mainly came into lime-light in case of Yoga. As a result, blending of the cultural practices of yoga of one place with another presented an inventive look to it, which is highly preferred and accepted by the citizens of modern age. However, by doing so, the cultural traditions and behaviours or attitudes of the individual of diverse culture might also be realised that may prove effective in reducing the rate of conflicts and clashes (Ritzer, 2007, pp. 912-923). Hence, such type of cultural acculturation or re-appropriation helps in enhancement of interpersonal relationships among the citizens of diverse culture and countries thereby improving the intensity of tolerance and frankness among the citizens. According to Howes (2007), values and ideas of consumer culture is extremely difficult to measure or determine. This is because these are hypothetical in nature and may be analysed or evaluated only by their acceptable nature. This means, if the norms or ideas or traditions of any culture is preferred or liked by any immigrant or individual of diverse culture, then it may be calculated by his or her behaviours or attitudes as stated by the theory of consumer acculturation (Howes, 2007, pp. 178-190). As a result of a theory of consumer acculturation, most of the citizens are accepting or preferring the blended forms of technology, cultural practices, products, manufacturing techniques, (Klien, 2000, pp. 223-234) marketing or promotional ideas and many others (Brenkert, 2008, pp. 123-134). For example: Yoga is considered as a rational set of practices develop in order to enhance religious or holy enlightenments. Yoga is performance in order to reduce the idea of ignorance thereby enha ncing the inner confidence and trust. By doing so, the impact of spiritualism enhances that improves the inner morale and buoyancy of the individual. However, in modern age, the concept or

The future of Liquefied Petroleum Gas (LPG) Dissertation

The future of Liquefied Petroleum Gas (LPG) - Dissertation Example Experts suggest that the energy industry takes a step towards this, because if they concentrate on making sustainable energy resources, they could play a crucial role in conserving energy (Williams, pp. 23-25, 2002). Thus, this has become a priority amongst car builders, manufacturers, and other people responsible. They are now concentrating on creating automobiles that will be most helpful in sustaining energies. Thus, the proposed research would be one small but significant step towards these efforts. Research Statement In this regard, the researcher will endeavor on the below-mentioned research statement to fulfill the aims and objectives of the research: â€Å"To identify and analyze the future of Liquefied Petroleum Gas in the energy market globally† LITERATURE REVIEW A study conducted by Qi, Bian, Ma, Zhang & Liu (2006) found out that Liquified Petroleum Gas (LPG) is a viable option and solution to the increasing pollution in China. Widespread use of LPG would mean that the country would emit lesser pollutants and dangerous gases due to the consumption of diesel and petrol based fuels. However, the study also recommended that for ensuring LPG has a bright future, experts will have to work to reduce the effects of one major disadvantage caused by LPG, and that be of the high auto-ignition temperature. The study experiments with the effects of replacing a diesel based automobiles with LPG-Diesel blended fuels at various blended rates that are 0 percent, 10 percent, 20 percent, 30 percent and 40 percent. The effects that were under examination were related to the engine performance and exhaust emissions that revealed that the effects on engine performance did not witness any significant impact; however, with increased LPG volume, the emission of sulfur and carbon oxides did decrease dramatically. Important here to note is that these findings are not in line with the findings of various other studies which have believed that LPG use as a car fuel incre ases hydrocarbon emissions (Gilbert & Perl, pp. 74-78, 2008; Song, Hsu, & Mochida, pp. 52-58, 2000). The Indian scientists, Ahuja, Dash & Shrivastava (2011) under the umbrella of â€Å"Department of Burns, Plastic, Maxillofacial, and Microvascular Surgery† in a recent research have revealed that LPG cylinders used for cooking are much safer in Indian households as compared to other means used for cooking. Furthermore, most of the LPG related incidents, which were reported in Indian households over the past 17 months, were in majority a result of negligence and inability to take care of the instruments. The study took into account various factors such as â€Å"age, gender, religion, socioeconomic status, literacy level, type of family unit, marital status, type of dwelling unit, mode of injury and its exact mechanism, place of incident, level of cooking stove, extent of burns† (Ahuja, Dash, & Shrivastava, 2011). In addition, some of the other factors were â€Å"presenc e of features of inhalation injury, number of patients affected in a single mishap, size of Liquified Petroleum Gas cylinder used, length of hospital stay and mortality† (Ahuja, Dash, & Shrivastava, 2011). Towards, the end it concluded that it is much safer for the lower and middle class Indian households, which are using kerosene related instruments for cooking. Therefore, the provincial governments should giver subsidy on the Liquified

Summary Essay Example | Topics and Well Written Essays - 1000 words - 4

Summary - Essay Example The author also adds that he shall cover the vital issues concerning anti-democratic perspectives in Islamic political thought, which touch on divine sovereignty. He concludes the abstract by stating he shall argue in favor of the core of human agency as a major factor in creating and suppressing these thoughts with regard to Islam and democracy. According to the author, although shura and bay’a are extensively covered in the Quran and Sunna, they are not discussed and dissected in detail. Rather, they have been created by the ijitihad of Muslim jurists, creativity, political thoughts, and interpretations (Ashour 1). He goes on to say that he shall also address some likely counterarguments: undemocratic decipher of the above-mentioned concepts, in addition to the most salient, and that is the Islamically-grounded argument related to the notion of divine sovereignty. The research question therefore, is: what are the foundations of, and barriers to, democracy in Islamic politica l notions. The author ends this section by confirming that his discussion will be focused on the previously-mentioned bases (bay’a and shura) and a major impediment (divine sovereignty as opposed to populist sovereignty). The conclusion will entail a general evaluation of the connection between democracy and Islam (Ashour 2). Defining Democracy This section begins with a distinction of the two main forms of democracy: liberal and electoral. Drawing on the work of Joseph Schumpeter, electoral democracy may be defined as an institutional framework for arriving at political decisions in which individuals gain the power to decide through competitive struggle for the votes of the populace. Electoral democracy may be illiberal, condoning the tyranny of the majority as de Tocqueville described. Electoral democracy must not include detailed provisions for protecting the rights of the minorities, nor does it need the absence of special domains of power, like those of the clergy and th eir concept of valyi al-faqih in Iran or Turkey’s military. On the other hand, liberal democracy is made up of many provisions for defending minorities against the tyranny of the majority. It also needs the absence of special domains of power for specific social groups like the clergy and the military. Is there an Islamic Political System? Experts on Islamic studies and Muslim political scholars are usually divided on this question, with two rejectionist factions at opposite ends of the divide and a lot of accomodationists sandwiched between them. The author states that all the arguments of the accomodationists (including the one on depoliticization) and the rejectionists base their justification and legitimacy at least partially (and in a majority of cases totally) on Islamic history and/or Islamic theological literature and scholars. It is virtually impossible therefore to present the argument that there is one sole special Islamic political system. In other words, as put b y two modernist Islamist scholars, â€Å"Muslims have a human comprehension of Islam†¦.it is erroneous for us to say that there is a particular system that symbolizes the Islamic system† (Ashour 3). Does Islam have a â€Å"Political Dimension†? After a consideration of various theoretical and empirical arguments, a look at the Islamic

Ryanair-The Southwest of European Airlines Case Essay Example for Free

Ryanair-The Southwest of European Airlines Case Essay Ryanair was founded in July 1985 by the three brothers, Catlan, Declan, and Shane Ryan, with the financial assistant of their father Tony Ryan. As a beginner commercial carrier, its operations began with 25 staff and a single 15-seat turbo-prop commuter plane between Waterford in the southeast of Ireland and Gatwick Airport, the second busiest airport in London after Heathrow. Later on, regulatory authorities permitted the Ryanair Airlines to have at least four flying flights a day on Dublin-London route, with more seating capacity. Nowadays, Ryanair, with its rapid growth, occupies the most sought position in its own field, being Britains favorite airline and the oldest-low cost air carrier in Europe. The goal of my internal analysis on Ryanair is to focus on resources and capabilities as internal sources of uniqueness that allow firms to beat the competition. This analysis is often called the resource-based view of the firm. By theory, a firm gains an advantage by obtaining valuable and rare resources and developing the capability to utilize these resources to drive customers toward their products and services at the expense of competitors. As a result, firms with superior resources and capabilities enjoy competitive advantage over other firms. Value Chain AnalysisFirms make products or provide services by engaging in many different activities. The basic structure of these activities is embodied in the firms value- chain. Value-chain activities are of two types: primary activities and supportive activities. Primary activities include inbound logistics, operations, outbound logistics, marketing and sales, and services. Support activities include human resources, accounting and finance operations, technology, and procurement. All the activities -primary and support are potential sources of competitive advantage or disadvantage of any firm. In Ryanair case, parts of the inbound logistics are Ryanairs low-cost deals, negotiated against promise of large and growing volume of business. Also, they include dependency on suppliers to deliver fuel as well as food, drinks and duty-paid products to be sold on-board; they need to be stored, handled and controlled upon delivery. The other important element of the primary  activities includes the operations. Ryanair fast turnarounds of 25 minutes are the companys core competencies. This is the most important cost advantage that enables high aircraft utilization. More frequent departures of two more per day than competitors with few planes, increases Ryanairs revenue. Point-to-point flights mean no interlinking with other carriers. Raynair offers direct non-stop journeys, avoiding the cost of providing through services for connecting passengers and delays caused by late arrival of connecting flights. Ryanair uses the standard model plane- Boeing 737, which means that company, is a ble to obtain spares and maintenance services on favorable terms, to limit the cost of staff training and to offer flexibility in scheduling aircraft and crew assignments. A relatively young fleet reduces maintenance, spare and fuel costs. Also, Ryanair placed resources to strengthen its core business such as satellite television, Internet service and arcade game, so the passengers can enjoy the trip. For outbound logistics, Ryanair uses isolated secondary airports, which often require further transport arrangements for customers. Also, some destinations are so geographically obscure that they cant support regular services to customer, as evident on some Scandinavian routes for example. This limits the level of market share Ryanair can achieve. EasyJet does the opposite and flies to big cities, but then have to pay higher landing charges which are reflected in their higher prices. However, using regional airports saves costs as charges are lower, facilities cheaper and Ryanair can negotiate favorable deals. It also enables fast turnaround times, and more on-time departures as the airports are less congested. 95% of Ryanairs flights are punctual compared to 88% for EasyJet. As I already mentioned, under primary activities are also marketing and sales. Ryanair considers branding virtually irrelevant as it believes that price is most important to customers. This reflects on companys image which isnt always so good in the press. In contrast Southwest Airlines, contribute a large part of their success to theirs well established brand values, and EasyJet has won awards for its brand. Ryanair invested resource to establish website for passengers. It made passengers more convenient. Spending on advertising and promotions to expand its market is reduced as most advertising takes place on the website. There promotion is also used to sell excess capacity, such as two-for-one offers, which creates market awareness. Over 90% of bookings  are made directly, either on the website or through reservations centers. The website saves on staff costs, agents commission, while significantly contributing to growth. Travel agencies are used on a small scale as necessary when opening new routes in unknown markets. Under services, Ryanairs virtually no-frills- lower costs considerably. The company enables fast turnarounds and offers very low ticket prices. But with less flight attendants, usually only two per flight, compared to five for the competitors, the quality of the services drops. The philosophy of Ryanair is that for passengers the price is more important than the quality. The low quality services could damage the brand name and this could lead to business reduction. Under support activities- the procurement, the purchasing power of the company enables negotiation of favorable deals with suppliers. However, these demand large and growing volumes based on passenger numbers. Although growth is slowed down new planes has been ordered aiming to double the fleet by 2009. Ryanair keeps good buyer-supplier relationships which ensure reliability and low-cost procurement of services. Many functions of the company are contracted out. Under human resource management, Ryanair aims to control its personnel cost by continuously improving the productivity. The staff is working under big pressure set by an overhead person and most commonly with feelings of dissatisfaction. The technology development factor of the support activities indicates that Ryanair uses its website (www.ryanair.com) to monitor bookings and to see how full planes are, all minute by minute. Also, the company uses its internet site as the major part of the business, which saved them about $6 million a year on an average. Resource AnalysisResources and capabilities are the fundamental building blocks of a firms strategy. The resource-based view presents a perspective of competition that portrays the value of a resource or capability as derived from the dynamic interplay of market forces. While the market and environment establish external constraints and pressures, a firms response through resource allocation and capability development become a source of competitive advantage. The resource-based perspective views a firm as an organization that has a bundle of protective resources and capabilities.  Resources are tangible and intangible assets a firm uses to choose and implement its strategies. Capabilities are the skills a firm uses to bring its resources to bear. Ryanairs tangible resources include all Boeing 737 airplanes the company uses, as well as the companys headquarter building in Dublin and all other buildings the company uses. Part of the tangible resources also are all of the supplies, food, drinks and duty-paid products company holds in inventory, as well as fuel. Intangible resources contain bigger part of the business. They include all the intellectual capital, like expertise and accumulated knowledge, experience, skills, abilities and talents that every employee in Rayanair possesses. Here I could include also the companys brand recognition, customer loyalty, investors confidence and the good reputation. Charismatic personality of the companys CEO- Michael OLeary is part of the organizational culture under the intangible resources. The capabilities of Rayanair are:-The lowest airfare rates, simple processes (no frills), large brand awareness, clear offer (focuses on particular market segment), the innovative strategies on cost cutting, and quick turnaround time-Learning curve (early entrant), accumulated much knowledge/experience, outstanding marketing and PR skills of the CEO OLeary- The company ability to bargain and get beneficial deals with suppliers; the efficiency and high turn-around rate, fast luggage handling and high punctuality- The ability to think strategically and assertively and to act on it: acquisition of Buzz-The expansion of new hubs and new added routes-The ability to control and cut costs, which are crucial to survive and succeed in the industry!-The ability to build and sustain brand (loyalty). Financial AnalysisRyanairs current financial objectives, strategies, policies and programs are clearly stated in their Annual reports and financial statements for 2008, which I have attached in the separate file. These financial objectives seem to be consistent with Ryanairs mission, objectives, strategies, policies of low fares, as well as with internal and external environments. There was an increase in profit after tax of 33%, which was because of 7% increase in average fairs, so profit margin was 19.66%. There was an increase in fuel costs by 50%, and staff costs rose  32%. The operating margin decreased by 1% (to 21% from 22%), which lead to an increase in operating profit by 28% compared to 2007. Total operating revenues increased by 32%. Maintenance costs increased by 12%, marketing and distribution costs increased by 71%, and aircraft rental costs increased by 23%. (Ryanair Holdings PLC, 2007). From this financial analysis, I could conclude that costs are increasing, but profit is also increasing leading to gains in the company. The statements are calculated in Euros, and there could be some differences based on the floating Euro/US Dollar exchange rates. In addition, this financial analysis supports Ryanairs past and pending strategic decisions, based on being a low fare air carrier. Ryanairs profit margin in 2007 is 19.66%, compared to EasyJet with 8.47% (2007), Air Lingus with 8.19% (2007) and British Airways with 5.48% (2007). If most companies in the same industry report decrease in profits, Ryanairs financial performance indicates that the company is in competitive advantage. (Ryanair Holdings PLC, 2007)Analysis of Strengths and WeaknessesStrengths and weaknesses are the major internal characteristics of firms, derived from the SWOT analysis. Firms within an industry generally have different strengths and weaknesses, and those differences often have a strong bearing o n which firms win competitive interactions. Ryanair strengths are:-Brand name: Ryanair through its 24 years in the Low Cost Carrier (LCC) market has developed a very well recognized brand name. -Benefits from low airport charges: These aid the low cost base Ryanair benefits from. -Has first mover advantage on regional airports (e.g. Charleroi): Acts as a barrier to entry-Internet site (94% bookings) www.ryanair.com : Lowers the cost of distribution as over the phone bookings are more costly. Eliminates the need of travel agents. -High seat density. -All Boeing aircraft: A uniform fleet saves on maintenance and training costs. -Fast turn-around. -High Service performance: Punctual, high rate of flight completion, low baggage loss, which give a good image of the companys reliability. -Modernized fleet which leads to less expensive maintenance: Will become more uniform with only one model (Boeing 737-800), also newer planes will require less maintenance. -High aircraft utilization: Ryanair flies its planes for longer thus generating more revenue from its assets. -Fuel and other risks hedging. -Small headquarters-Point to point flights: No hub and spoke, lowers cost as no through services requiredRyanair weaknesses are:-Prone to bad press: Rayanair is perceived as arrogant and the slightest incident with the scandal commercial gets a lot of press coverage. -Niche market: Restricted expansion possibility. -Distance of some regional airports from advertised destination: Over time customers may find this a big inconvenience. -Poor service: Ryanair decreased the number of flight attendants per flight, which decreased the service quality. -Ryanair is extremely sensitive to changes in charges (increase in fair value)In conclusion I would like briefly to summarize the strengths and weaknesses I mentioned above. Ryanair carries out its routine checks and repairs on its aircraft using its own engineers which means that some maintenance costs are included in the staff cost. Also the company has cost advantage, because of its ability to achieve 25 minutes turnarounds and therefore can run two more flights a day in its schedule than rivals such as British Airways. Their use of secondary airports means that they are able to negotiate deals with the airports, in contrast to larger airlines unwilling to split their operations between two or more airports. Ryanair does not pay dividends to its shareholders. All profit is reinvested back into the business, which means a higher profit margin. Ryanair is unable to expand its home market industry, because of airport taxes. Passengers having their own luggage carried at their own risk could mean a loss of reputation if any major scandal is to occur in terms of loss of luggage. Increasing its fleet could mean that it might incur more losses. Reference: Thompson, A.A., Strickland, A.J., Gamble, J.E. (2008), Crafting executing strategy;The quest for competitive advantage.

Research Assignment on Data File Structure

Research Assignment on Data File Structure Raghavendra Tyagi TOPIC OF ASSIGNMENT The letters in English language, make up words. While no word is less or more than another, one could view a word that appears before another in the dictionary is less than that word, and a word that appears afterwards is more. By this definition, identical words are the same. Parsing a file is when you read a file to collect information from the file. In this assignment, you will parse a file, and put all of the words in a Binary Search Tree. You will use the Binary Search Tree to collect data about the number of times a word was found in the file. The first word you encounter will be the root. If the next word is greater, put it to the right. If it is less, put it to the left. It is possible that the tree you make will be very sparse. Assume all words in the file are lower case or covert them to lower case. After you have loaded the file into your Binary Search Tree, the program should display the in-order, pre-order post-order traversal of the Binary Search Tree. The user should be given the chance to type a word. The computer should say the number of times the word was found in the file (zero or more). BINARY SEARCH TREE INTRODUCTION: In  computer science, a binary search tree (BST), sometimes also called an ordered or sorted binary tree, is a  node-based  binary tree  data structure which has the following properties The left  sub tree  of a node contains only nodes with keys less than the nodes key. The right sub tree of a node contains only nodes with keys greater than the nodes key. The left and right sub tree each must also be a binary search tree. There must be no duplicate nodes ADVANTAGE: The major advantage of binary search trees over other  data structures  is that the related sorting Algorithm and  search algorithms  such as  in-order traversal  can be very efficient. BINARY SEARCH TREE (PROPERTY): Letxbe a node in a binary search tree. Ifyis a node in the left sub tree ofx, theny. key x. key. OPERATIONS: Operations, such asfind, on a binary search tree require comparisons between nodes. These comparisons are made with calls to a comparator, which is a  subroutine  that computes the total order (linear order) on any two keys. This comparator can be explicitly or implicitly defined, depending on the language in which the binary search tree was implemented. SEARCHING: Searching a binary search tree for a specific key can be a  recursive  or an  iterative  process. We begin by examining the  root node. If the tree isnull, the key we are searching for does not exist in the tree. Otherwise, if the key equals that of the root, the search is successful and we return the node. If the key is less than that of the root, we search the left sub tree. Similarly, if the key is greater than that of the root, we search the right sub tree. This process is repeated until the key is found or the remaining sub tree is null. If the searched key is not found before a null sub tree is reached, then the item must not be present in the tree. INSERTION: Insertion begins as a search would begin; if the key is not equal to that of the root, we search the left or right sub trees as before. Eventually, we will reach an external node and add the new key-value pair (here encoded as a record new Node) as its right or left child, depending on the nodes key. In other words, we examine the root and recursively insert the new node to the left sub tree if its key is less than that of the root, or the right sub tree if its key is greater than or equal to the root. DELETION: There are three possible cases to consider: Deleting a leaf (node with no children):Deleting a leaf is easy, as we can simply remove it from the tree. Deleting a node with one child:Remove the node and replace it with its child. Deleting a node with two children:Call the node to be deletedN. Do not deleteN. Instead, choose either its  in-order  successor node or its in-order predecessor node,R. Replace the value ofNwith the value ofR, then deleteR.

Succubus Heat CHAPTER 8

Grace called me that night while I was on my way to talk to Isabelle. â€Å"Hello, Georgina. This is Grace.† I waited patiently for Mei's complementary greeting. When it didn't come, I asked in surprise, â€Å"It's just you? Not Mei?† Grace's voice, while as flat as usual, held the tiniest puzzled note in it. â€Å"Why would Mei be here?† It apparently hadn't occurred to her that I had never received a call or a visit from either of them alone. They always functioned as a unit, kind of giving the impression that the fabric of the universe might rip open if they were ever apart. This was as weird as them nearly accepting coffee the other day. â€Å"Never mind. What's up?† â€Å"Jerome wanted me to tell you that he is†¦pleased.† â€Å"Over what?† â€Å"Over you successfully embarrassing Cedric.† â€Å"But I didn't-† I bit my lip, suddenly wondering if I should be so quick to deny my involvement. Jerome hadn't been happy with me recently. While the stupid spectacle at Queen Elizabeth Park had put me on Cedric's shit list, it might very well take me off Jerome's and hasten my permanent return to Seattle. I stayed silent. â€Å"He's glad you took his talk to heart,† Grace continued. â€Å"Although, he does wish to remind you that you being sent to Cedric is supposed to be a gesture of good will. So try not to be too efficient. Jerome encourages you to keep up with these small jabs but to remember that you do ultimately want this group undone.† I sighed. â€Å"Noted.† Grace disconnected. Great. This was all I needed. Jerome thought I was guilty too-of trying to score extra credit with him. Cedric had told me I could find Isabelle at a jazz club a few miles from my hotel. It was over on a street lined with clubs and bars, and the excitement and energy in the air as I walked toward Isabelle's hangout was palpable. It was Saturday night, after all, and the streets teemed with humans eager and excited for life and love. I couldn't see their souls or energy the way an imp like Hugh could, but I didn't need to. It was apparent in the way they moved and talked and eyed each other for potential hook-ups. Even after my recent tryst, being in this electric atmosphere made me itch for another conquest. I'd have to cruise these clubs once I'd concluded business with Isabelle. The jazz club was small and dark, exactly the way you expected such places to be. All the tables were filled, and lots of people stood by the bar or along the wall. I didn't have any trouble finding Isabelle, though. The signature of a greater immortal filled up a place like this. Hers made me think of sunlight shining through crystals, fracturing into sparkles of color. She sat alone at a corner table. Most obviously single women in there were being hit on-in fact, I got a number of appraising looks as I walked through-but no one other than the wait staff seemed to notice Isabelle. It reminded me of how no one ever noticed Jerome's resemblance to John Cusack. Isabelle wore a long blue dress with spaghetti straps, surprisingly risqu? ¦ for an angel. Her hair was sunny blond and worn loose to her lower back-not unlike a golden cloak, I thought wryly. She sensed me, of course, and didn't seem surprised at all when I sat down across from her. With a smile, she glanced up and crooked a finger toward the nearest waiter. He hurried over and took my gimlet order. Once he was gone, Isabelle turned her attention on me. â€Å"So. Jerome's succubus.† Cedric had called me the same thing when we first met. I kind of resented my identity being based on my association with-or rather, possession by-someone else. â€Å"Yeah,† I said. She watched me pleasantly, neither cold nor friendly. With angels, you never knew which extreme you might get. Mostly, she looked curious, so I figured I could get right down to business. â€Å"So I-â€Å" â€Å"Shh.† â€Å"Wh-â€Å" She held up her hand, dark eyes focusing on something beyond me. The band was in the middle of a song, and the trumpet player had just put the instrument to his lips. A long, high note came out, kicking off what turned into a mournful solo. When he finished a minute or so later, I turned back to Isabelle and saw the waiter had brought my gimlet. The angel's face was alight with wonder-and wistfulness. â€Å"Did you hear that?† she asked me. â€Å"Those notes weren't complicated, yet he managed to put so much into them. His heart, his emotions, his soul. A world of sorrow, exquisite agony†¦all in those few notes.† She took a sip of her wine. â€Å"You can't do that. Not even I can do that-not the way he did.† Her words surprised me, but I knew exactly what she meant. Part of the reason I was always a little in awe of Seth's books was because he, as a mortal, had a talent that an immortal like me never could possess. â€Å"Only humans have the gift of creation,† I murmured. Her eyebrows rose slightly, and she smiled. â€Å"Yes, exactly. So tell me, what can I do for you, Jerome's succubus?† I felt a little weird interrogating her now. There was something a little sad and vulnerable about her that made her appealing. Nonetheless, I pushed forward. Angels and demons came from the same stock. Both were good at making you believe what they wanted. â€Å"You†¦you know about those so-called Satanists, right? The Army of Darkness?† Isabelle's smile twitched. â€Å"Great movie, silly cult. Did you have anything to do with their display today? I really liked the goat mask.† I shook my head. â€Å"Actually, I was wondering if you had anything to do with it.† â€Å"Me?† She laughed. â€Å"I only wish I could think up things that good-but there we are again: humans and creation. Why do you ask?† â€Å"Because they say they're being directed by an angel.† I gave her an abridged version of what the group had told me. â€Å"And you assume they literally meant an angel?† â€Å"I'm trying not to assume anything. But I think someone or something is directing them, and your side has as good a reason as any to stir up trouble for Cedric and make the authorities on all sides come down on him.† â€Å"And your side has just as good a reason. Demons try to oust each other all the time.† I tapped my nails along my glass's edge and eyed her warily. â€Å"And you haven't actually answered my question,† I pointed out. â€Å"You haven't directly denied being involved.† Angels couldn't technically lie, but oh, they were masters at not always telling the truth. Isabelle finished off her wine and smiled at me again. â€Å"Oh, you are delightful. This is just like being on a TV cop show. No wonder Carter likes you so much.† I sighed in exasperation, realizing I was going to get nowhere. Fucking angels. Her grin dimmed a little, but she was still clearly amused. â€Å"Look, Georgina,† she said. She knew my name; no real surprise. â€Å"I like you. You're clever and endearing, but here's how it is: I don't want to see Cedric leave Vancouver. I like him. And anyway, that saying about keeping your enemies close is true. I know him, I understand him. And when you're playing a game like ours, the better you know the pieces on the board, the better you'll do. I don't want to have to live with an archdemon I don't know, one who's a lot more unpleasant than he is.† A new glass of wine had been delivered, and she paused to take a sip. â€Å"And that's the truth.† I didn't know what to say. I wanted to believe her but had no idea if I could. I simply sighed again. â€Å"What are you thinking?† she asked. â€Å"I wish I could believe you when you say you aren't involved. Even with the whole not-lying thing, I don't know that I can. I don't think that I can trust anyone.† â€Å"That,† she said firmly, â€Å"is absolutely something I agree with: you can't trust anyone. On any side. Everyone's got their own agenda, and there's something in the air right now-it's like a building storm, to use a clich? ¦. Be careful.† Her face looked momentarily troubled, and then she relaxed again as her attention returned to the stage. â€Å"Ah, the soloist is back.† I slid my empty glass to the center of the table. I started to take out some cash too, but she waved it away. â€Å"Thanks for talking,† I told her, rising from my chair. Suddenly, I hesitated. â€Å"You mentioned Carter. I don't suppose†¦I don't suppose you know where he's been lately?† I'd never thought I would utter those words. Carter had tormented me for years with his unsolicited, cryptic advice. He'd particularly loved to comment about Seth and me, as though he had some special interest in our relationship. Since it had ended, I'd hardly seen Carter at all. He used to come hang out with my friends and me but had only surfaced a couple of times in the last few months. Isabelle smiled. â€Å"He's closer than you think.† â€Å"Typical angel answer,† I groaned. I turned around to leave and then yelped. Carter stood by the club's entrance. Abandoning Isabelle, I hurried across the crowded room. Oblivious to the dress code, Carter wore his typical grungy clothing, ratty jeans and a plain gray T-shirt. A flannel shirt was tied around his waist, and his blond hair could have handled a good washing and brushing. He smiled expectantly at my approach and stepped outside to the crowded street. I followed. â€Å"What are you doing here?† I asked, taking out my cigarettes. I grabbed one for myself and then offered him the pack. He took one too. â€Å"What are you doing here?† he returned pleasantly. â€Å"You know what I'm doing here. Everyone knows what I'm doing here.† I fumbled in my purse for my new lighter and found a matchbook instead. I pulled it out. Mark's Mad Martini Bar. I'd forgotten them. â€Å"What's wrong?† asked Carter, noting my frown. I shook my head. â€Å"Nothing.† I traded the matches for my lighter, and we lit up. â€Å"You were lurking with your signature hidden,† I continued. â€Å"Why?† â€Å"Element of surprise,† he said. â€Å"It was worth it to see your face.† We walked past the club lines and drunken groups, no clear destination in mind-at least none that I knew of. â€Å"You haven't been around in a while,† I accused. â€Å"Why, Daughter of Lilith, have you missed me?† â€Å"No! But I was starting to feel like you were only interested in me while I was dating Seth.† â€Å"Of course not.† There was a long, overly nonchalant pause. â€Å"So†¦have you talked to him lately?† I rolled my eyes. â€Å"You are only interested in Seth! You're going to have to let it go, Carter. Seth and I are finished. Why can't you obsess on me and my new boyfriend instead?† â€Å"Because you can do better.† â€Å"Everyone keeps saying that. But I'm a succubus. How much better can I do?† â€Å"The fact that people keep telling you that should be answer enough.† â€Å"Seth broke up with me ,† I said through gritted teeth. â€Å"He doesn't want me anymore, end of story.† â€Å"Oh, come now. Do you really believe that?† â€Å"Seeing as I was there at the break-up? Yes.† Carter tsked. â€Å"Georgina, Georgina. You're letting your anger and other emotions cloud your reason, which is unfortunate since you're a lot smarter than people give you credit for. Go back and think. Why did Seth break up with you?† I stared off at the far side of the street, refusing to look at him. â€Å"Because he thought if we stayed together, we'd both get hurt. That it would be better if we split, no matter how painful at the time.† â€Å"And you think that makes him a bad person?† â€Å"Yes.† I turned back toward Carter. â€Å"Because I didn't agree. I was willing to take the risk. He gave up.† â€Å"Sometimes it takes more courage to know when to retreat than to keep fighting.† â€Å"I don't think it could have taken that much courage. He ended up with Maddie pretty quickly.† No matter how hard I tried, I couldn't keep the bitterness from my voice. â€Å"That takes courage too, forcing yourself to start over with someone new, to keep moving on with your life.† â€Å"Seems more like a rebound to me.† Carter took a long drag on his cigarette. â€Å"Seth didn't leave and go to Maddie because he stopped loving you. If there were no complications in the world, you would be the one he chose. You are his ideal, his first choice.† â€Å"That's not flattering to Maddie.† â€Å"It doesn't make her less. It just means he loves her differently. And when you decide you have to move on, that's how it is. Just because things don't work out, it doesn't mean there aren't other people you can't love. Love is too big a thing for you to go without it in life.† â€Å"Oh yes,† I said. â€Å"I have so missed these cryptic conversations.† Carter crooked me a grin. â€Å"I'm glad to see you're back to your old self.† â€Å"I've missed the sarcasm too.† â€Å"No, I'm serious. You weren't a lot of fun these last few months. You were kind of†¦Ã¢â‚¬  â€Å"†¦bitchy?† He shrugged. â€Å"I don't know. You were angry and depressed and frustrated. You stopped caring about the people around you. You weren't†¦well, you.† â€Å"You don't know me or what I am.† â€Å"I know you better than you think. I know you're still hurting and think the universe has given up on you. It hasn't. I also know that as far as all this demon business is concerned, your curiosity is going to tangle you up further in something you shouldn't be involved with in the first place. Jerome,† he declared, â€Å"is a fool.† â€Å"Do you know what's going on?† I asked eagerly, coming to a stop. â€Å"Who's leading that cult? Who's supposedly running this huge game that's going on that I can't see?† â€Å"No,† said Carter, expression dark. â€Å"I don't know any of that. But if I were you, I'd get back to Seattle soon. Stay close to Jerome.† â€Å"He hates me right now.† â€Å"No, he doesn't. Stay close to him. He'll protect you. If he can't†¦well, I will. If I can.† There was nothing romantic in his offer of protection. It wasn't spoken with chivalrous fierceness. His manner was uneasy, like he was dealing with a last resort. I also couldn't help but replay his last words: if I can . Angels-or demons-didn't use the word â€Å"if† very often. â€Å"What do you mean if-â€Å" â€Å"Go back home, Daughter of Lilith.† He tipped his head back to stare at the night sky, blew smoke into the air, and then looked down at me with his silvery gray eyes. â€Å"We'll talk soon.† He dropped the cigarette to the sidewalk and vanished. I glanced around, worried someone had seen us, but we'd walked far from the partiers. I stamped out the cigarette, turned, and headed back in the direction of all the nightlife to go find some guys I'd noticed checking me out. A night with drunken men might still leave me feeling hollow, but at least their motives were easier to understand than angels'.

Chemistry Study Guide Acids and Alkalis

Interactive Science 2B Chapter Summary | | Chapter 10 ComMon Acids and Alkalis 10. 1 Acids and Alkalis 1. Acids taste sour. Many fruits contain acids. 2. The three mineral acids commonly found in the laboratory are hydrochloric acid, sulphuric acid and nitric acid. 3. Alkalis taste bitter and feel soapy or slippery. 4. The common alkalis found in the laboratory are sodium hydroxide solution, potassium hydroxide solution, calcium hydroxide solution and ammonia solution. 0. 2 Acid-Alkali Indicators 1. An acid-alkali indicator shows different colours in acids and alkalis. It can be used to test acids and alkalis. 2. Natural indicators can be made from some deeply coloured plants. 3. Acids turn blue litmus paper red whereas alkalis turn red litmus paper blue. Distilled water does not change the colour of litmus paper. It is a neutral substance. 4. The pH value shows the degree of acidity or alkalinity of a substance. 5. The pH value of a substance can be measured by using universal indic ator, pH paper or a pH meter. 6.Low pH values mean high acidity (or low alkalinity). 7. High pH values mean high alkalinity (or low acidity). 8. Substances with pH values < 7 :acidic; pH values = 7 :neutral; pH values > 7:alkaline. 10. 3 Acids and Corrosion 1. Dilute acids react with some metals and produce hydrogen. 2. Test for hydrogen: Put a burning splint near the mouth of a test tube containing the gas. If the gas is hydrogen, it burns with a ‘pop' sound. 3. The rate of reaction of some metals with dilute hydrochloric acid or dilute sulphuric acid: maznesium > zinc> iron > copper (no reaction) . Carbonates react with acids and give carbon dioxide. 5. Marble and limestone mainly contain calcium carbonate. They are used as building materials and they can be corroded by acids. 10. 4 Safety Related to the Use of Acids and Alkalis 1. Strong acids / alkalis are corrosive. Weak acids / alkalis are generally less corrosive. 2. Dilute acids / alkalis contain a low percentage of ac ids / alkalis. Concentrated acids / alkalis contain a high percentage of acids / alkalis. 3. Concentrated strong acids and alkalis are highly corrosive. 4. Safety measure in handling strong acids and alkalis |Reason | |(a) Stick the hazard warning label ‘corrosive ‘ on the surface|To warn users about the corrosive property of the chemicals. | |of the container. | | |(b) Wear safety spectacles. |To prevent the acids and alkalis from getting into the eyes. | |(c) Put on protective gloves. |To prevent our skin from contact with the acids or alkalis. | |(d) Wear laboratory coat. |To prevent damage of clothing and body. |(e) Work in a fume cupboard. |To prevent vapours of the acids or alkalis from irritating our| | |eyes and respiratory system. | 5. To dilute a concentrated acid or alkali, always add it slowly to a large amount of water with stirring. Never pour water into a concentrated acid or alkali. 6. The first step in treating acid or alkali spillage on our body is to w ash with plenty of water. 10. 5 Acid Rain 1. Clean or normal rain has a pH value of 5. 6. 2. Acid rain has a pH value lower than 5. 6. 3. Practice test:Â  answer keyAcid rain is mainly caused by the acidic pollutant gases sulphur dioxide and nitrogen oxides. 4. The main sources of sulphur dioxide and nitrogen oxides in the air are motor vehicles, power stations and factories. 5. Acid rain may ? corrode structures made of metals, marble and limestone, ? kill fish and plants in lakes and rivers, and ? slow down plant growth and even kill plants. 6. The government, industries and citizens should work together to reduce the release of sulphur dioxide and nitrogen oxides, which cause acid rain. 10. 6 Neutralisation 1. An alkali and an acid can neutralise each other. . Neutralisation occurs when an alkali is mixed with an acid until the resulting solution becomes neutral (pH = 7). 3. When an acid is neutralised with an alkali, a salt and water are formed. The word equation for neutralisation is: Alkali + Acid (Salt + Water 4. Antacids are weak alkalis used to neutralise excess acid in the stomach. 5. Weak acids, such as eth anoic acid in vinegar, can be used to neutralise the alkaline stings of wasps. 6. Weak alkalis, such as baking soda (sodium hydrogencarbonate), can be used to neutralise the acidic stings or bites of bees, ants and mosquitoes. . Weak alkalis, such as slaked lime (calcium hydroxide) and powdered limestone, can be added to acidic soil to raise the pH for plant growth. 8. Acids in industrial wastes can be neutralised by adding alkalis such as sodium hydroxide, while alkalis can be neutralised by adding acids such as sulphuric acid. 10. 7 Daily Uses of Acids and Alkalis 1. Acids and alkalis can be used in cleaners to remove stains and grease. 2. Acids such as ethanoic acid can be used to preserve food. 3. Acids can be used to prevent the browning of fruits. ———————– [pic] [pic]

The report investigates the computing capabilities of smartphones, and their ability to support several multimedia applications. The report discusses that fact the smartphone industry has rapidly grown over the last two decades. Currently, rapid transformation is taking place and competition to control the lucrative market has increased. The report considers whether the market segment is controlled by a few major players . The reports investigates patent issues amongst the major players The PESTLE framework is used to analyse the business environment in the smartphone market. Porter’s Five Forces is also used to evaluate the rivalry and power of the individual players within the smartphone industry. Introduction According to Ahson and Ilayas (2006), a smartphone is a form of mobile device that integrates the characteristics of a phone and a PDA. A smartphone offers more advanced connectivity and computing capabilities. Smartphones have the ability to access the Internet and support several multimedia applications. Smartphones achieve the capabilities of a Personal Computer technology and a traditional phone (Ahson and Ilayas, 2006). They enable users to add, install, and delete hundreds of applications. Users can also personalize the interface. They have ushered the present society into an era of ubiquitous information. The report examines the global-local aspects of the smartphone industry, specifically the patent wars. It also provides an analysis of the smartphone industry using the PESTLE framework. The report further provides an evaluation of the rivalry and power among the smartphone players. It discusses the competitive advantage within the smartphone industry. Global-local aspects of the smartphone industry.Smartphones; Markets and growth trendsPark, et al (2011) hypothesize that the mobile phone industry has witnessed a significant change in the last 15 years. In the last decade, Nokia was the world’s leading manufacturer of mobile phones. Since then, Nokia has been dislodged from the leading position by the new smartphone companies such as Apple, Samsung, and LG. The success of these companies is due to the introduction of new modern and innovative approaches to the ease of use of hardware and an improved user interface design (Park et al 2011). Himmelsbach (2013) argues that, in the recent years, the smartphone industry has witnessed radical transformation and altered competitive situation. The major players in the market segment include Samsung, Apple, Huawei, Sony, LG, HTC, Nokia, Research in Motion, Microsoft, and Google (Park et al 2011). . There are also other indirect players such as Qualcomm and Cirrus Logic. The intense c ompetition among the market players has led to large volumes of complex and mostly multi-jurisdiction patent litigation (Himmelsbach, 2013). The economic downturn caused the traditional global phone market to enter recession (Ahson and Ilayas, 2006). However, the smartphone market has been growing rapidly (Himmelsbach 2013). Major players have expanded their total sales due to the growing number of smartphone users and the reduced prices. Smartphone industry PESTLE analysis (Henry, 2008). Factor AnalysisPolitical analysisPolitical environment in some countries enable smartphone markers to flourish Political challenge in some countries, for instance, China, and India raised security concerns over some features provided by RIM’s BlackBerry. Roaming fees is relatively high in several countries Economic analysis The current prices of smartphones devices are fair although devices from some major manufacturers such as Apple are still considered to be expensive Slow economic growth and recession can affect the sale of smartphone devices Social analysis Some major smartphones brands symbolize high status.Innovation is increasing getting hard.Technological analysis The main rivalry is between Apple’s iOS and Android operating systems. Innovation is rapidly growing and each day, a new technology is invented. Environmental analysis Manufacturers are required to comply with various environmental standards. Legal analysis Patent lawsuits is increasing among the smart phone industry players.Patents in the smartphone industry.According to Hill et al (2014), the smartphone industry has experienced patent litigation for several years. In the past, voice telephony services such as speech compression technologies, network management and radio transmission were the main focus of patent litigation. More recently, patent litigation has broadened across a wider range of cellphone and mobile computing technologies. The major market players are continuously suing each other over a variety of smartphone patents. The role of patents in the smartphone industry is to protect a company’s investment in research and development (Hill et al 2014). After an examination of a patent, the owner is granted a monopoly license for the patented invention which is usually 20 years. Patents provide incentive to the owner company for its effort of bringing the innovative technology out of the research lab and into the market after an expensive and risky business. The N etwork Patent Analysis method indicates that large portion of the patent portfolio is held by Apple (Ferell and Fraedrich, 2014). Apple is slightly ahead of IBM and Microsoft. According to NPA, 16 out of the 20 patent are owned by Apple. NPA reveals several of the smartphone patent lawsuits are within the 16 unique clusters of inventions that are related. Hill, Jones and Schilling (2014) note that the majority of smartphones patent wars are related to mobile data access, touch screens and transmission of mobile data. Among the three clusters, each has different company or manufacturer dominating the patent portfolio. According to Hill, Jones and Schilling (2014), the mobile data access cluster is dominated by Research in Motion, while the touch screen cluster is dominated by Apple. Evaluation of the competitiveness (rivalry) and power of the individual players within the smartphone industry using Porter’s five forces. Smartphone devices have become part of many people’ s lives. The market has been largely fractionalized. The transformation of the smartphone market has led to increased competition and rivalry. Different players are producing devices tailored for different market segments. Porter’s Five Forces can be used to understand the forces affecting the smartphones market from the manufacturers and users perspectives. The five components of Porter’s framework in relation to the smartphone industry is as follows. The threat of new entrants is low because the investment on the required technology needed to compete in this industry is high. Consumers purchase phones from incumbent companies with good reputation. This explains why Apple, and Samsung smartphones are the most popular in the market. The threat of substitutes is low because smartphones contain added functionalities from other digital electronic devices such as watches, digital cameras, cell phones, pager, and organizers, and laptops. The service provided by smartphones are sufficient as expected from a mobile device. The bargaining power of buyers is rated to be medium because the present smartphones market contains a variety of products from major brands for consumers to choose. The prices of smartphones have become relatively low. The bargaining power of suppliers is medium because of the reliance of mobile phone manufacturers on their suppliers. The manufactures acquire quality components from suppliers at competitive prices. Som e smartphone operating systems such Android is open source. The smartphone industry is competitive with a few strong competitors (Boyes and Melvin, 2012). New entrants find it challenging to compete and gain in the market share which is dominated by major brands. However, some new smartphones manufacturers such as Sony and ZTE are rapidly gaining popularity and market share. Competitive advantage within the smartphone industry. The smartphone market is highly competitive, and it has experienced dramatic changes in the recent past. In 2007, Apple defeated BlackBerry from the leading position as the dominant smartphone maker Laffey (2011). Smartphone market competition has also been based on the two main operating systems, Google’s Android and Apples’ IOS (Park et al 2011). Apple has managed to take the leading position in the market because of its high specification products, integrated operating system and quality hardware (Laffey, 2011). Apple’s success is also attributed to its luxury brand image established during the reign of Steve Jobs Apple provides the eco-system of apps available online on Apple’s app-store platform (Park et al 2011). The Kindle Fire, an Amazon product is expected to challenge Apple by offering readerse new opportunities to access to Amazon’s online e-books store (Laffey, 2011). Amazon’s relationship with content providers will enable it secure the delivery of its apps and video content providing a new competition across the market segment (Laffey, 2011). The difference in pricing between Android and IOS phones has impacts on competition (Laffey, 2011). Most Android smartphones are affordable while some devices from Apple are less affordable. Apple benefits from a higher income from this (Laffey, 2011). Conclusion In summary, the current smartphone is no longer exclusive for early adopters. Streamlining of new innovations has led to increased competition and patent litigation. It is evident that the smartphone market is controlled by a few major smartphones makers. Smartphones have heralded a new era in the communication industry and changed several aspects of human lifestyle. New software makers need to develop an operating system to make a unique distinction in the current market. References Ahson, S. and Ilayas. (2006) Smartphones [online]. Intl. Engineering Consortium.
