Social Breaching Exercise free essay sample

People sometimes assume what might not be real. I took my daughter age 3, my niece age 4, and my cousin’s daughter age 6 to the mall by myself. My own reaction was â€Å"would I be able to handle this kids by myself at a public place. † We left and as soon as I started walking through the mall the first reaction was everyone looking at me as if I was weird or I had something on my face, my kids were asking to go to the Disney Store nothing much, no screaming or doing nothing out of the ordinary, I had asked myself why everywhere I went they will just turn and look at the kids and then at me. I had figure that maybe it was because I was alone with three small kids, until I overheard someone say â€Å"so young and with three kids† I couldn’t believe what their reaction was for me having three kids.

Lawrence is my home town, unfortunately is very common for young girls to have kids at a young age, and is more like a Stigma everyone in this area will always assume that if you are taking care of a child or have a baby in your arms will automatically think that you are the mom of that child. By looking at this people I realized and for a moment felt out of place, but I changed my thoughts by just saying to my self â€Å"I’m married and have my precious daughter who is only 2 and I’m only 26, good for my age† It seams to me that even me knowing this from the start their reaction made me question myself for a few seconds, and at the same time I was able to see with my own eyes how they look at this girls who really have multiple kids at a young age and how they might feel. In conclusion our everyday life is so much different, people make it different, it is a shame that people will go these limits of making you feel out of place. This is not much more of trying to hide the truth, but all girls in general don’t have to feel ashamed of what had happened and people doesn’t make it much easer either. I’m sure that these girls have their on dilemmas to work on imagine going out and dealing with people too. I would have to say that I wanted to say something to that person, but I held back since it was just and experiment, but imagine if it was true, I had in my head the stigma of having a child young more so multiples. These people actions of stigmatisms seem to provide these people with joyless pleasure and a temporary sense of superiority and it blinds them to the reality that is humanity.

Definition and Examples of Back-Formation

Definition and Examples of Back-Formation In linguistics, back-formation is the process of forming a new word (a neologism) by removing actual or supposed affixes from another word. Put simply, a back-formation is a shortened word (such as edit) created from a longer word (editor). Verb: back-form (which is itself a back-formation). Also called  back-derivation. The term back-formation was coined by Scottish lexicographer James Murray, the primary editor of the Oxford English Dictionary from 1879 until 1915. As Huddleston and Pullum have noted, There is nothing in the forms themselves that enables one to distinguish between affixation and back-formation: its a matter of historical formation of words rather than of their structure (A Students Introduction To English Grammar, 2005). Pronunciation: BAK for-MAY-shun Examples and Observations singular noun pea from the older English plural peasethe verb burgle from the older English noun burglarthe verb diagnose from the older English noun diagnosis He spoke with a certain what-is-it in his voice, and I could see that, if not actually disgruntled, he was far from being gruntled, so I tactfully changed the subject. (P.G. Wodehouse, The Code of the Woosters, 1938) Here I was maybe forty minutes ago, sort of claustrophobed in the gap between the kickass movie world where Lila dumps the guy with the smarmy mustache and the obvious one where it just keeps getting later.(Daniel Handler, Adverbs. Ecco, 2006) Stripping the in- from inchoate is known as back-formation, the same process that has given us words like peeve (from peevish), surveil (from surveillance) and enthuse (from enthusiasm). There’s a long linguistic tradition of removing parts of words that look like prefixes and suffixes to come up with roots that weren’t there to begin with. (Ben Zimmer, Choate. The New York Times, January 3, 2010) Suffix Snipping Alan Prince studied a girl who . . . was delighted by her discovery that eats and cats were really eat -s and cat -s. She used her new suffix snipper to derive mik (mix), upstair, downstair, clo (clothes), len (lens), brefek (from brefeks, her word for breakfast), trappy (trapeze), even Santa Claw. Another child, overhearing his mother say they had booze in the house, asked what a boo was. One seven-year-old said of a sports match, I dont care who theyre going to verse, from expressions like the Red Sox versus the Yankees. (Steven Pinker, Words and Rules: The Ingredients of Language. HarperCollins, 1999) In many cases of back-formation a presumed affix is removed which is in fact not truly an affix, as in the following words where the -or, -ar, and -er are not the agentive suffix, but part of the root: orator - -er orate, lecher -er lech, peddler -er peddle, escalator -er escalate, editor -er edit, swindle -er swindle, sculptor -er sculpt, hawker -er hawk. These mistakes are called back-formations. Note that some of them are colloquial or marginal, while others are fully accepted. (Laurel J. Brinton, The Structure of Modern English: A Linguistic Introduction. John Benjamins, 2000) Back-Formation in Middle English [T]he weakening of the flexional endings during the early Middle English period, which made possible the derivation from verbs of a multitude of nouns, and vice-versa, was also as essential to the rise of and development of back-formation. (Esko V. Pennanen, Contributions to the Study of Back-Formation in English, 1966) Back-Formation in Contemporary English Back formation continues to make a few contributions to the language. Television has given televise on the model of revise/revision, and donation has given donate on the model of relate/relation. Babysitter and stage manager have given babysit and stage manage for obvious reasons. More remote was the surprising lase from laser (the latter an acronym for lightwave amplification by stimulated emission of radiation), recorded from 1966. (W.F. Bolton, A Living Language: The History and Structure of English. Random House, 1982) Filling a Void Backformations are more likely to occur with very strongly entrenched patterns and they have the effect of filling an apparent void. The process has given us common verbs such as afflict (from affliction), enthuse (from enthusiasm), laze (from lazy), liaise from liaison), aggress (from aggression), televise (from television), housekeep (from housekeeper), jell (from jelly), and many more. (Kate Burridge, Gift of the Gob: Morsels of English Language History. HarperCollins Australia, 2011) Usage [B]ack-formations are objectionable when they are merely needless variations of already existing verbs: back-formed verb - ordinary verb*administrate - administer*cohabitate - cohabit*delimitate - delimit*interpretate - interpret*orientate - orient*registrate - register*remediate - remedy*revolute - revolt*solicitate-solicit Many back-formations never gain real legitimacy (e.g.,  *elocute, *enthuse), some are aborted early in their existence (e.g., *ebullit, *evolute),  and still others are of questionable vigor (e.g., aggress, attrit, effulge, evanesce, frivol). . . . Still, many examples have survived respectably. (Bryan Garner,  Garners Modern American Usage, 3rd ed. Oxford University Press, 2009)

Words to Describe Fearful Recoil

Words to Describe Fearful Recoil Words to Describe Fearful Recoil Words to Describe Fearful Recoil By Maeve Maddox Writers are constantly reminded Show, dont tell! One way to be more descriptive in our writing is to use verbs that convey movement. Here are some words that describe movement prompted by fear, cowardice, or pain. flinch [flÄ ­nch] to draw away in anticipation of pain. The prisoner flinched when the guard raised the whip. The nobleman did not flinch as he mounted the steps to the guillotine. The soldier marched unflinchingly through the hail of arrows. shrink [shrÄ ­ngk] to draw back as if trying to make ones body smaller. One might shrink into the shadows in an attempt to become invisible. Figuratively it has the sense of avoiding danger, often used with a negative: He did not shrink from battle. By the way, the principal parts of this verb are shrink, shrank, (have) shrunk. wince [wÄ ­ns] One might wince from pain, real or anticipated. The patient winced as the dentist probed the painful molar. She winced when he called her fat. Flinch, shrink, and wince all derive from words meaning bend, turn, or turn aside blench [blÄ•nch] I used to think blench included the idea of turning pale along with recoiling. However, it is not related to blanch. It just means move suddenly, wince, or dodge. cower [kouÉ™r] Although the word looks as though it might have a connection with coward, it probably comes from a German word meaning to lie in wait. In current usage it conveys a cowardly or fearful movement. The sailor cowered under the lash. The frightened puppy cowered under the porch. cringe [krÄ ­nj] In Old English the word could mean to fall dead in battle. Now it has the less final meaning of to draw back or move in a fearful manner. The servant had a cringing manner, as if moving in constant fear of being struck. The nurse cringed as the demanding patient rang the bell for the twentieth time in ten minutes. grovel [grÃ… vÉ™l, grÃ… ­v-] This is a word to use when the action takes place close to the ground. It conveys the sense of demonstrating servility by dropping onto ones knees, or even going face down. Figuratively it can be used of people too eager to please. Deprived of his weapon, the enemy grovelled in the dirt, pleading for his life. quail [kwÄ l] Although spelled the same as the name of the game bird, the verb to quail, to lose courage, to shrink, is not related. Its origin is uncertain. Words meaning to be ill, to die, and to curdle have been suggested. In current usage, quail means to draw away in fear or weakness. He quailed at the prospect of climbing the mountain a second time. Want to improve your English in five minutes a day? Get a subscription and start receiving our writing tips and exercises daily!

Product Design and Development Management [Brand creation and Essay

Product Design and Development Management [Brand creation and development] - Essay Example Karl Speak even argues that marketplace position and intimate relationships are today valued above profitability. The present â€Å"information age† has turned consumer culture development and brand relationships as the new â€Å"best practice† in business (49). What makes branding an important marketing tool, is that â€Å"the brand image is enduring in the minds of the customer† (Montague 17). Branding is a powerful instrument to counteract market negative pressures, because branding makes companies, products and services visible and distinct; it prolongs products life cycles, and allows companies to sustain costs and prices to levels that are less dependent on competition. Developing a strong brand identity that is consistent with corporate strategy is therefore the recipe for long-term success. Brand identity refers to the degree a product has achieved a distinct image in the eyes of consumers and the general public (Schmitt et al 83). â€Å"It’s corporate strategy made visible.† (Peters 11). Brand identity is closely related to customer impressions, meaning the image a product or a company actually has, as opposed to product or corporate expressions, meaning the image that is desired (Schmitt et al 84). Often companies produce positioning statements that describe how the brands should be positioned in the minds of customers. These statements are the backbone for branding strategies that attempt to minimize the gap between desired brand image and actual identity. Brands make promises for unique product experience. Delivery of those promises is therefore crucial for creating lasting impressions and loyal customers. The brand management profession commands a range of tools for successful brand development. These are graphic standards, conformity to corporate identity, marketing communications sending consistent brand

Hypotheses and evidence (SPSS) Assignment Example | Topics and Well Written Essays - 500 words

Hypotheses and evidence (SPSS) - Assignment Example Most of the values (40%) were concentrated above the mode, which despite some other variables showing normal distributions, advised my use of non-parametric tests on the data. The sample comprised 30 participants, 56.7% being male and 43.3% females. 20% were engaged, 13.3% were married, and 3.3% were single. The majority, 63.3%, did not indicate to belong to any of these three categories. Most participants were college graduates (63.3%), 20% high school graduates, and 16.7% had attained post-graduate levels. 40% earned between $50001 and $75000, 20% between $25000 and $50000 and also $100000 and above, 13.3% between 75001 and $100000, and 6.7% below $25000. I sought to establish whether alcoholic drinks are popular with the participants, who are generally assumed to represent the parent population they have been drawn from. From the sampled population, 60% were consumers of hard drinks, which include vodka, whiskies (where scotch falls), and brandy among other drinks. Out of this population, 56.7% consumed wine, and 43.3% consumed mixed alcoholic drinks. The entire sample confessed to using other types of alcoholic drinks. Classified under this criterion, 3.3% consumed â€Å"Hard Lemonade† while the remaining 96.7% consumed â€Å"Long Island Tea†. The percentages for all four categories indicate high consumption rates of alcoholic drinks, with every participant indicating they consume them. I performed a Chi-square test to establish whether individuals reported to drink more or less at the time of the survey. 30.0% of the respondents reported to drinking more, with a similar ratio drinking less. 40% drank the same amounts of alcohol. The test showed that the proportion of those who drank more was not significantly different from those who drank less, and those who maintained equal drinking volumes (χ2 = 0.60, p = 0.741). I further performed a Chi-square test to establish whether more consumers of alcoholic drinks took their drinks over the

Mental impairment Essay Example for Free

Mental impairment Essay The law of not guilty due to mental impairment in Victoria, Australia was started as a simple experiment in the mid nineteen nineties as a result of the a case that involved victims that were released from prison on the account of not being guilty on the ground of mental impairment which was initially known as insanity (Patelis, 1996). Such a decision was always made by the Governor after consulting with the cabinet on the way forward. Afterwards, it was shifted to the courts that were concerned with sentencing. The victims who had initially been the favorites of the politicians and the Governors for that matter ended up waiting for long periods of time for their cases to be determined by the courts immediately after this change was effected (Patelis, 1996). This change in the legislation was to mean that the people who were to be released on the grounds of not guilty by reason of mental impairment had to be detained in the precincts of the court for at least a period of time for the purpose of their own security and the security of the community at large. This was part of implementing the obligations that were recognized internationally on the principles of protecting the insane people and also those who had mental problems. The law had been interpreted by the seventy supreme courts in Victoria by the year two thousand and four. To date, this body of law constitutes one of the very vital organs in the mental health section. Factors that cause differences in opinion toward Mental impairment defense. In Victoria and other parts of the world, there are factors that cause people to react negatively towards defenses based on the ground of insanity or mental impairment (Feusch, 1980). This is an issue that is one of the mostly contested about and has ended up generating a lot of debates among many people including those who support the ideas and those who are against the ideas. Many view it with very strong opposition and cannot see the reason why someone should be released or acquitted by the courts on grounds of mental disorders. Such releases have really led to a lot of heat and therefore mistrust towards the said defense and resulted to general bias of the defense (Feusch, 1980). Some states have been forced to go ahead and abolish this kind of defense by the increasing number of outcries from the public. An example is the release of a victim in the United states of America after he attempted to assassinate the then president in the year nineteen eighty one. The president was Reagan Ronald. A lot of changes and shifts in the law about insanity defense came soon after this attempted assassination with many of them concentrating on the not positive public outcry. These negative views and opinions are not only found in the U. S but cut across many mixed cultures (Menzy, 2002, pp. 379). Many of the attitudes facing the defense on insanity can be termed as genuine but one wonders, for how long? The media has also played a role that is looked at as being negative and has led to negative opinions and stigmatization among people on the misuse and abuse of the defense on insanity. Jurors have also been affected by these allegations. Most of them would go to court with minds that are already influenced by the media or by the mare perception of insanity thus ending up passing verdicts that are uninformed and misplaced. There are two main concerns that show case as to why the public has different views on the insanity defense cases (Menzy, 2002, pp. 82). Albeit the misperceptions exist, one would argue that they are uninformed. The first highlight is that, the people look at the defense on insanity grounds as a mare scape goat by which victims of crime can avoid court prosecution and hence punishment. Such beliefs oftenly make the public feel that the criminals evade their rightful justice and yet they have committed crimes. The other reason is that, lack of accurate and correct information about such cases of insanity lead to criticism and negative reaction by the public. The truth is that even if the jurors and the judges are given the right number of cases that involved mental illness, they end up exaggerating the figures by making them look as if they were too many thus inciting the public to have conflicting reaction on the same (Jons, 1999). Such ideas that are misinformed could lead to general bias that influence the decision concerning the mentally ill thus leading to unfair judgment in most of the cases. Case Studies. New Zealand(NZ). In NZ, the people who are found to be not guilty by reason of insanity(NGRI) are released by the courts under special conditions. They undergo treatment, rehabilitation and monitoring by the forensic services on mental health(FMHS) (Jons, 1999). Some of the patients are treated as special cases and can only be released or discharged upon the assent of the minister in charge. This of course, depicts the concern of the public about the risk that is bound to be faced if such people are taken back to the society. The FMHS department has the task of both seeing to it that the patients recover on time and also making sure that the public is protected against such patients. Despite the presence of the FMHS department, there is still the concern about the likelihood of the criminals to go back to the society and cause more crimes and havoc (Peter, 1982, pp. 2). Such cases have not been focused on critically by the FMHS and is becoming a stigma to both the mentally ill and those in the community at large. The acquittees on mental grounds are rehabilitated for a long period of time until such a time when the outcomes are inevitable. Also as a way of treating the patients, the public is to be informed so that their attitude changes in order for there not to be any form of stigma (Peter, 1982, pp. ). A research was carried out by students of a local University on the outcome of the efforts by the FMHS, the patient treatment duration and also looked at the rates at which the criminals are committing crimes after being acquitted. The findings of the research suggested that those offenders who committed major crimes were detained for a long period of time than those who committed less serious offenses. It went ahead to point out that patients were released on the basis of their recovery and not on the duration of time they spent in the hospitals. In England and Wales. In England, there was a scenario in which a person of an adult nature was detained on the grounds of having committed a crime and yet he was mentally ill. The victim had been referred to the hospitals mental rehabilitation unit by one of the courts in England (Finke, 1989, pp. 403). It meant that the doctor who was taking care of him was in charge of renewing his detention period but was not in charge of carrying out medical examinations in case of any challenges arising about the case. An independent doctor would be brought in to carry out the examination in order to avoid biasness. The patient had been classified as one with acute mental disorder and yet in real sense, he was suffering from confusion and a state of disturbance, a condition he developed in his early adulthood (Finke, 1989, pp. 406). Several doctors refused to reclassify him and suggested that he belonged to the mental rehabilitation clinic. A medical officer ones examined the patient and gave contradicting views from those of the other doctors. They then came to an understanding that the patient would be reclassified. Thereafter, several cases of the sort came up but were treated differently from the first one (Finke, 1989, pp. 08). In Australia (Victoria State). It is very clear under section twenty cap one of the crimes Act of nineteen ninety seven that only a person suffering from mental disorder and that he/she is proved to have committed a crime at a time when he was suffering from the illness, can be allowed to used the defense of mental impairment. This meant that the person either committed the crime and was not aware of the quality and nature of the crime or the person was not aware that the conduct and manner with which he/she committed the crime was not right (Finke, 1989, pp. 405). Here in Victoria, if a person is found to be not guilty on the grounds of NGRMI(not guilty by reason of mental impairment, the person is declared to be put under supervision by the court as per part five of the crimes act of nineteen ninety seven or the court declares the person to be unconditionally released. The order may give conditions on the release or may put the defendant in custody. The order is then supposed to be reviewed by the supreme court of justice and by its discretion may order that the person be released. Such reviews are really taking center stage in Victoria. There were a number of attempts aimed at allowing the courts to look for alternative measures to be put in place in order to address the issues of mental impairment. The problem that arose was that the alternatives were planted fully on the courts and not the other organs of government (Capylon, 1984). This led to a situation where there was no significance in the decrease of the number of people who were accused to have committed crimes. The type of system adopted was the Governors pleasure system(GPS) and it was viewed as being unfair by some people. This system could detain someone in custody for a very long period of time and yet the person is genuinely mentally ill (Capylon, 1984). In some cases, the system would propose that the victims be detained in the hospitals for a longer period of time than what was required. It is quite obvious that different people get different treatment in terms of administering verdicts and this is as a result of the type of system being used in Victoria. Some of the cases need a longer period of time on treatment while others require shorter lengths of time. This system does not recognize that. The crimes act, for instance, says that a judge passing a judgment of NGRMI(not guilty by reason of mental impairment), may unconditionally discharge or take an order of supervision (Capylon, 1984). After that, the supervision of the victim is maintained by the court at all times unless otherwise stated. The legislation simply means that its main motive is not to punish the victim but to take care of the safety of the public. In any circumstance, it must be the scenario because the accused has not yet been proved guilty by the courts. Besides, the safety of the victim is also of paramount importance and therefore, care should be taken at any stage of the case in order to avoid further interference with the mental condition of the accused. The courts of appeal and the high courts have time and again deliberated on the issue of dangerousness. The issue is very vital in deciding whether or not a person is supposed to be kept in custody or be taken to the detention facilities. This is thought to present a bone of contention between the different tribunals and organs of law (Capylon, 1984). It goes without saying that the adopted reforms have gone a long way to address the issues of dealing with the mentally impaired and the insane in regard to the type of crime they might have committed and the condition is which they committed the crimes. Such reforms go out of the way to address the difficulties encountered while dealing with the problems brought about by mental insanity. These reforms suggest to some extend that the identified problems be given new solutions with the aim of solving them ones and for all (Feusch, 1980). It is however, very difficult to rule out any possibilities of challenges arising concerning the reforms. Such challenges include researches on the brains functionality and the possibility of studying the behavior of humans. These when done, will be of paramount use when dealing with such issues in the future. The problem of dangerousness predictability is the major worry at hand as it is assumed that the moment a person commits a crime in the first place, he/she is bound to do the same time and again. This of course is a wild goose chase when the NGRMI is applied to such like a situation (Feusch, 1980). This debate has opened a Pandoras box and has made courts to take an approach that is conservative when acquitting the victims who have the ability of causing harm to the community and to themselves in the future. This type of approach goes hand in hand with the high courts principles on sentencing which says that the society should be protected against any form of harm and be given the first priority (Feusch, 1980). One would say that it is in the area of psychology that bigger and greater ideas are to take place. Such advances to some extend will give solutions to the predicaments associated therein. Approaches such as complete treatment of the mental illness using therapy and strong medication are highly recommended. Recommendations. Much efforts should be put in place in order to address the problem of dealing with mental impairment and insanity. Reforms should be made in the existing legislations in order to seal any loopholes that might see some people getting unfair verdicts during judgment as others face the full force of law (Peters, 1982). It is therefore in the best interest of the courts, tribunals and the public at large to spearhead the implementation of such reforms in order for there to be fairness in the way such cases are handled. Proper approaches should be made so that victims acquitted on grounds of mental impairment and insanity are taken care of so that they do not become a menace in the society and to themselves too. Conclusion. It is rather uncalled for that despite the many approaches and advances that have been made in the recent past, no much effort has been put in place to adopt them and implement them cross board. Differences have been witnessed in the manner in which verdicts have been passed in different jurisdictions as it turns out to be unfair in some situations depending on who is being judged. This in itself is a challenge that needs to be addressed and a viable solution be found and effected with adequacy. Further research is needed in this field to address the various problems that are causing ripples in the courts of law and in the judiciary at large. If these are not addressed, there are bound to be a lot of problems in the corridors of law.

Discovering the Things that Make Us Human: Evolution of the Brain :: Biology Essays Research Papers

Discovering the Things that Make Us Human: Evolution of the Brain There is a powerful sentiment among many people that human beings are the most intelligent and complex animals on earth. Our ability to use language is matched by no other species. It makes sense to assume that whichever characteristics of the human brain arent possessed by other animals, specifically primates, our closest evolutionary relatives, are the ones responsible for the acquisition, production, and comprehension of language. As the relatively new field of neuroscience develops, scientists are beginning to study the evolutionary relationships of brain organization and function in an effort to understand the regions of the brain responsible for language, abstract thought, and self-expression. This discipline, known as Paleoneurology, examines the development of the hominid brain (1). Paleoneurology has its roots in the fields of neurology, paleoanthropology, and primatology. There are two methods used by Paleoneurologists to study brain evolution: the examination of fossil sku lls and endocasts, and comparative primate neuroanatomy (2). The study of the evolution of the brain is useful, because it allows for an understanding of the origins of the structural differences between humans and other animals--in effect, what makes us human. According to the fossil record, the first brain structure appeared in reptiles around 500 million years ago. The functions of this hindbrain included breathing, heart beat regulation, balance, basic motor movements, and foraging skills (1). An interesting trend in brain evolution is that more evolved species tend to preserve the structures responsible for basic behaviors. In other words, evolution is the process of acquiring more and more sophisticated structures, not simply the addition of different structures. Therefore, the modern human brain contains the primitive hindbrain region, often called the protereptilin brain (1), and it is the seat of fundamental homeostatic functions. The major structures found in this region of the brain are the Pons and Medulla. About 250 million years after the appearance of the hindbrain, a new region known as the paleomammalian brain arose. This region consists of the hippocampus and cerebellum and is often referred to as the limbic system. As mig ht be expected, this region is associated with more complex functions such as emotional, sexual, and fighting behaviors (1). The newest and most intricate area of the brain, the cerebrum, was first developed around 200 million years ago. The highly convoluted surface of the cerebrum is called the neocortex.

Definition of Some Symbols

Some people seem to think that the red cross which is used as a symbol by the American Red Cross and International Red Cross is a Christian symbol – and therefore that these organizations are Christian in character. I don't know why, but these people don't seem to realize that cross are and have been used as symbols outside of Christianity. Media Matters reports: [A]ccording to the American Red Cross website, it was â€Å"[i]n honor of the Swiss †¦ that] the symbol of a red cross on a white background (the reverse of the Swiss flag) was identified as a protective emblem in conflict areas. † While the cross on the Swiss flag originated in the 1200s from â€Å"a symbol of the Christian faith,† according to the Swiss Embassy in the United States, the Red Cross makes no mention of Christianity as a reason for adopting the symbol. †¦ In addition to stating that its symbol was chosen as the reverse of the Swiss flag, the American Red Cross website adds that â€Å"[t]he Red Cross idea was born in 1859, when Henry Dunant, a young Swiss man, came upon the scene of a bloody battle in Solferino, Italy,† and that the â€Å"emblem was adopted at this first International Conference as a symbol of neutrality† at the first-ever Geneva Convention at Geneva, Switzerland, in 1864. Media Matters put up this information to explain how Bill O’Reilly was incorrect to use this as an example for why it’s wrong to remove the large Christian cross from Mt. Soledad in San Diego. O’Reilly isn’t the only person who thinks that the red cross is a Christian cross, though — that appears to be a belief held by many Muslims and why Muslim organizations use a red crescent. Vehicles with a red cross on them might be targeted as a Christian vehicle in wrong place. Thus, Christians like Bill O†™Reilly who are trying to defend Christianity are making the same mistakes as non-Christian terrorists who would like to attack Christianity. The irony of this is truly astounding. It is confusing because most people think of a â€Å"cross† as the Christian symbol, the murder weapon. The cross or plus sign on the Swiss flag is actually a symbol of the Christian faith as well so the red cross flag, a symbol which is derivative of the Swiss flag, is also a Christian symbol. The plus sign is in all aspects a cross in the religious sense and does represent a specific religion on the Swiss flag as well as the red cross symbol. I might as well be in the shape of the murder weapon itself more traditionally presented by religious people. There is a red crescent flag and a red star of David flag as well, clearly religious symbols which were made as alternatives it the Christian cross or plus sign on these flags. Identification * The red cross symbol is a four-armed cross that resembles two perfect rectangles placed to look like a cross. There is no lettering, and the symbol usually appears on a white background. Significance * The symbol is the international sign for medic. It is associated in the U. S. with the American Red Cross, a nonprofit aid agency that helps those in need, regardless of their ability to pay. History * The cross was one of many symbols used to signify medic until the introduction of firearms to battle and the increase in casualties. Henri Durant designed the red cross as we know it today after witnessing tens of thousands of soldiers left dying on the battlefield with no one to help them. As I understand it, the red cross was a symbol designed to identify medical personal during wartime – it was meant to be a symbol of protection. It is a reversal of the Swiss flag, in honour of the Red Cross founder, Henry Dunant, who was swiss. So nurses and other medical personal wore a red cross to identify themselves. Nursing was at the core of the Red Cross movement from its inception. Nowadays, the Red Cross has come to be associated with disaster relief and other humanitarian efforts. the red cross represents many things such as unity, peace, hope, and the color of our blood The crescent moon and star is an internationally-recognized symbol of the faith of Islam. The symbol is featured on the flags of several Muslim countries, and is even part of the official emblem for the International Federation of Red Cross and Red Crescent Societies. The Christians have the cross, the Jews have the star of David, and the Muslims have the crescent moon, right? What is the history behind the crescent moon symbol? What does it symbolize or mean? How and when did it become associated with the faith of Islam? Is it a valid symbol for the faith? The crescent moon and star symbol actually pre-dates Islam by several thousand years. Information on the origins of the symbol are difficult to ascertain, but most sources agree that these ancient celestial symbols were in use by the peoples of Central Asia and Siberia in their worship of sun, moon, and sky gods. There are also reports that the crescent moon and star were used to represent the Carthaginian goddess Tanit or the Greek goddess Diana. The city of Byzantium (later known as Constantinople and Istanbul) adopted the crescent moon as its symbol. According to some reports, they chose it in honor of the goddess Diana. Others indicate that it dates back to a battle in which the Romans defeated the Goths on the first day of a lunar month. In any event, the crescent moon was featured on the city's flag even before the birth of Christ. The early Muslim community did not really have a symbol. During the time of the Prophet Muhammad (peace be upon him), Islamic armies and caravans flew simple solid-colored flags (generally black, green, or white) for identification purposes. In later generations, the Muslim leaders continued to use a simple black, white, or green flag with no markings, writing, or symbolism on it. It wasn't until the Ottoman Empire that the crescent moon and star became affiliated with the Muslim world. When the Turks conquered Constantinople (Istanbul) in 1453, they adopted the city's existing flag and symbol. Legend holds that the founder of the Ottoman Empire, Osman, had a dream in which the crescent moon stretched from one end of the earth to the other. Taking this as a good omen, he chose to keep the crescent and make it the symbol of his dynasty. There is speculation that the five points on the star represent the five pillars of Islam, but this is pure conjecture. The five points were not standard on the Ottoman flags, and as you will see on the following page, it is still not standard on flags used in the Muslim world today. For hundreds of years, the Ottoman Empire ruled over the Muslim world. After centuries of battle with Christian Europe, it is understandable how the symbols of this empire became linked in people's minds with the faith of Islam as a whole. Based on this history, many Muslims reject using the crescent moon as a symbol of Islam. The faith of Islam has historically had no symbol, and many refuse to accept what is essentially an ancient pagan icon. It is certainly not in uniform use among Muslims. Why We Look Up – Lascaux is a World Heritage Site and late Upper Paleolithic cave complex in southwestern France that belongs to the Magdalenian Culture. Lascaux's cave paintings were made c. 15–18,000 B. C. The sophistication of the Lascaux cave paintings is extraordinary when considered against their great antiquity. Their subtlety, complexity of technique and metaphor are qualities we can immediately relate to. The full articulation of this cave art reveals a mind akin to our own. If time and language barriers could be set aside, it is very possible that Magdalenian people of the late Upper Paleolithic would understand us, and that in return we could understand them. What do these great paintings tell us? Aurochs and other large animals portrayed in Paleolithic cave art were often hunted for food. The act of painting them in a sacred cave has often been interpreted as an important element in a ritual that invoked sympathetic hunting magic. The act of a painting the animal sends a message to its spirit, that great respect is intended and that only those individuals essential for tribal survival will be hunted and killed. The spirit world and the gods are asked to ‘understand' and not penalize the human sphere. The act of painting, the actions and protocol by which these paintings are executed, is the ritual. The finished painting is a record of the ceremony. It is a static reminder of the bond between the spirit world and humankind and of the obligations each ‘world' owes to the other. We do not know if these great animal paintings were prayed to. We do not know if Paleolithic religion venerated and prayed to icons.

At the beginning and end of time, all the ‘worlds' are integrated and melded into an indescribable whole and ‘oneness'. This final and beginning state of reality is the adamantine bliss of yoga and Buddhist cosmology as typified by the god Brahma. It is often created by the cosmic dance of the multi-armed Shiva. It is everything and nothing, timeless and beyond words.

This is a multidimensional, mythological layer whose journey in the millennia to follow will connect with Stonehenge as a future article shall discuss. This deeper layer is also metaphysical and mathematical, and relates to the adamantine oneness of Vedic, Hindu and Buddhist cosmology. The complexity of mind revealed in late Upper Paleolithic cave art is akin to that expressed much later in history by ancient Vedic philosophers whose art form was Sanskrit poetry. Mathematical aspects in late Upper Paleolithic mythopoetics derived from observational astronomy. Some cave paintings recorded an understanding of the path the moon takes around the sun – the ecliptic. An understanding of the ecliptic leads to the discovery of the zodiac, the annual path of the sun through the celestial sphere. A construct for the zodiac then follows, in which it is divided into twelve sections later known as ‘houses'. Stars, moons and planets in Upper Paleolithic culture are not the stars, moons and planets of modern astrophysics that we know. They are deities whose habitat is the Milky Way and the celestial sphere. Mathematics is art, as Plato knew well. If the annual journey of the sun, moon, visible planets and some very bright stars can be tracked and recorded with enough precision to enable accurate prediction, then the human ‘world' has understood a great deal about the gods. We are no longer passive because we know where these celestial entities go during their year's sojourn and what those journeys portend for life on earth. The gods do not travel alone, nor are they unconcerned about human welfare. We are their acolytes and worshipers, and the only beings that can nourish the gods. We are the only sentient beings beside the gods themselves. This is not a child's game where Paleolithic astronomer-shaman-priests looked into the night sky to find the silhouettes of familiar animals in the geometrical arrangement of stars in the night sky. We can be fairly confident that star gazing at night was not frivolous. It was a search for realities that were believed to exist. What might be those truths? These early artifacts and cave paintings reveal a deep conviction that there was a spirit world inhabited by deities, and that some or all of that ‘universe' was above us and was celestial. Another portion of the universe was below, an ‘underworld' that was the antithesis of the celestial. The ‘world of the gods' was not chaotic. Observational astronomy was the premier empirical science of the time. Astronomer-priests discovered that the ‘world' of the gods was multidimensional and precisely organized by number and time. Pattern through time, provides consistency, a belief in structure and the possibility for prediction down the time track of the future. Look up, think and perhaps the manifestations of several deities can be seen, if they wish that to be seen by humans. When the Late Paleolithic astronomer-priests found the gods in the heavens, they confirmed that the gods do wish to be seen by us, that their celestial form is recognizable and stable, and does not change from night to night. Dr. Michael Rappengluck of the University of Munich has long believed that Magdalenian Culture of the late Upper Paleolithic in Europe looked at the night sky and ‘saw’ the Milky Way. They also discerned several bright, prominent arrangements of stars which could be described and integrated into a mythology. These arrangements of stars were the first constellations to intrude into human culture. Organized into a celestial landscape that winds its way through the Milky Way and upon which the Sun will travel, the earliest Zodiac had been found and mapped. As Plato said about mathematics, it is not an invention of human genius. It has always been there, waiting to be discovered. Lascaux – Two Aurochs / Taurus, Scorpio Photo – Prof saxx / Wikipedia The two aurochs that face each other were aligned with arrangements for the constellations of Taurus and Scorpio. They also correspond to the rising and setting opposition of two fixed stars: a) Aldebaran, which is the eye of the bull in the constellation Taurus; and b) Antares which is in Scorpio. Understand that there are several aurochs depicted on the cave walls in the Hall of the Bulls, but only one depiction of the constellation Taurus the Bull. Why do the Bulls predominate, why is Taurus the dominant constellation? Taurus is not the Solar God unless we make him so. The eye of the auroch that is Taurus is the supergiant star Aldebaran in the center of the constellation. The open star cluster Hyades encircles, and the Pleiades is above, the shoulder of Taurus. Culture would be the behaviour – context would be anything else eg climate, geography, raw materials and technology available. So smoke signals would reflect a culture and the fact that on open plains you can see such signalling.. Cave paintings are the root of traditional illustration, one the earliest of which has been in recent news, a ‘faint red dot' dated to more than 40,000 years ago. These were discovered in 11 caves in Spain, and results show that they are at least 15,000 years older than we first thought. It raises many questions; What are they trying to say? Who made it? Is it symbolic? Who was it made for? No matter what the answers are, illustration is a means for people to convey information, a means of visual communication. The purpose of these cave paintings are unknown, and we can only speculate as to their actual purpose. A time well before printing press, but the value of visual communication has lasted through the ages. One thing that is for sure is it was some sort of communication via visual aids, they had a purpose and had something to say. As you understand from the title, this blog is going to be about the History of Visual Communication Design, that actually had started many many years ago†¦ First of all, visual communication means, â€Å"the communication of ideas throufh the visual display of information. Primarily associated with two dimensional images, it includes: art, signs, photography, typography, drawing fundamentals, colour and electronic resources. Recent research in the field has focused on web design and graphically oriented usability. It is part of what a graphic designer does to communicate visually with the audience. † (from http://www. citrinitas. com) History of Visual Communication Design has actually started with the paintings on rocks and caves in Europe with Cro-Magnons, who form the earliest known European examples of Homo-sapiens. It is known that they are descending from populations of the Middle-East and lived from about 40,000 to 10,000 years ago in the Paleolithic period of the Pleistocene epoch. Cro-Magnons were anatomically modern. They are only different with their partly stronger physiology and brains that have larger capacity than that of modern humans. After they arrived in Europe (about 40,000 years ago), they brought sculpture, painting, body ornamentation, engraving, music and decoration of utilitarian objects, there. Tools that were survived by Cro-Magnons comprise of huts (small dwelling), carvings, cave paintings and antler-tipped spears (weapons). By the way, antler means horn of animals in the deer family, so we know that they used to hunt animal not only for food, but to make weapons, too. The remains also suggest that these people knew how to make woven clothing. More over their huts were constructed of rocks, bones, clay, branches and animal fur. It is possible that Cro-Magnons have created the first calender around 15. 000 years ago, with their knowledge of painting pictures with manganese and iron oxides. Cave Paintings â€Å"Cave or rock paintings are paintings painted on cave or rockwalls and ceilings, usually dating to prhistoric times. Rock paintings are made since the Upper Paleolithic, 40,000 years ago. It is widely believed that the paintings are the work of respected elders or shamans. † They mostly used to draw/paint large wild animals, like bisons, aurochs, horses, deers and tracing of human hands. Of caurse they have depicted abstract forms, too. † (from http://www. citrinitas. com) Researchers think that cave art may have

Words Are Mightier Than the Sword

Ayoub Awadalla Prof. Brumfield October 9, 2012 Words Are Mightier Than The Sword The story â€Å"By Any Other Name,† by Santha Rau, explains the memory of the writer’s first and last week as a student at an Anglo-Indian school. Santha Rau speaks about the happy, sad, and embarrassing moments she had in school. She also speaks about how earning a â€Å"valid† education, in western terms, is difficult to achieve in India. When someone is in an environment where it is typical to hear insensitive and irresponsible language, s/he will likely become insensitive and irresponsible.Insensitive and irresponsible speech typically becomes a chain reaction. Once someone speaks or says an insensitive or irresponsible thing, the other person will follow with being insensitive and irresponsible. An example was when Permila, Santha’s older sister, was getting ready to take a test, but the teacher made her and the other Indian kids sit in the back with a desk in between eac h other. The teacher said, â€Å"It was because Indians cheat. Once Permila heard this insensitive statement, she stormed out of her class, marched into Santha’s class and told her â€Å"get up, were going home. † When she got to Santha’s class, the teacher smiled at her in a kindly and encouraging way and said â€Å"now, you’re little Cynthia’s sister? † Permila wore a poker face that did not betray a single emotion. Treating Santha’s teacher with an insensitive way, just like her teacher treated her. Changing a name of a child is a confusing matter for the child to understand.A child is a stranger when it comes down to lying. Most children, from ages of 3-6, are innocent and do not know how to lie. The head mistress changed Permila’s name to Pamela, and Santha’s name to Cynthia. Santha was too young to understand and was okay with the name changing. Permila kept a â€Å"stubborn silence† while Santha replied, à ¢â‚¬Å"thanks you. † And when the teacher asked Santha for her name, she replied, â€Å"I don’t know. † She was confused; thus, did not know if she should say her real name, or the new name she received from the head mistress.This act by the head mistress was very irresponsible. She was too lazy to call Santha, her real name, so she gave her an artificial name. Being rude, insensitive, or speaking irresponsibly to someone will most likely cause him or her to be rude, insensitive, or speak irresponsibly to you too. One must be carful of what s/he speaks, because what comes around, goes around. Just like the head mistress spoke to the girls insensitively and irresponsibly, they both left the school and never went back.

Free Essays on Should The Government Legislate Morality

Should the Government Legislate Morality There are many things to consider when asking the question, â€Å"Should the government legislate morality, or not?†. People seem to have a difficult time agreeing on moral issues. What is morally correct in the minds of some may not be correct in the mind of another. Is it up to our government to distinguish a definite line between the morally acceptable and the unacceptable? David Pendleton believes so. In his article, he states that the government already imposes moral beliefs on its people. He believes that the laws enforced are guides to lead people on a more moral path of life. On the other hand, Charley Reese writes about why the government should not legislate morality. He states it is not the job of the government to direct its people on how to live their life. Reese blames our immoral country on its people, and thinks it is their responsibility to do something about it. One of Pendleton’s main points is that of public and private morality. He tries to blur the line of privacy by stating that everything a person does affects everyone else, be it directly or indirectly. Then he follows up with â€Å"others have good reason to be interested in how I live my life† (193). I could not disagree with his statement more. This is a weak attempt to prove his point about the difference in public and private affairs. Another argument Pendleton makes is that â€Å"it’s hard to have a society when the things people have in common are too few† (192). I find this weak because I believe in a diverse community. He is saying that people who do not have similar beliefs can not live together in society. The only weakness I found in Reese’s article was his aggressive nature.

Airframe Structure Failure and Survivability

There are many different variables that come into play during an aircraft accident. It is an investigators job to find out what caused the failure. Failure of an aircraft primary structure is ranked high on the list of risks aircrews would rather not face. Mechanical component failure which can lead to loss of control of the aircraft is not far behind. Another issue which must be addressed in any aircraft accident is the question and of crash survivability. Even if no one was injured the investigator must find out what worked and what didnt. If there were injuries, several questions should be asked. The chapters I will be covering will give the investigator a look into what causes structural failure, and how to determine crash survivability. An aircraft accident investigators job is to determine what caused the crash. Structural failure is a vital part of the investigation. The term structure failure means where the material fails to carry below it was intended to carry. A structure can fail in one of two general ways. One way is it can be fractured, which means broken into two or more pieces. Another way is when the structure shape is changed so that it can no longer carry its load. With this kind of failure, the structure is still in one piece. It could be bent, stretched, corroded, or so worn that it can no longer do its intended job. Over the next few pages, I will be going into detail about the different ways structures can fail. There are many reasons why an airplane structure can fail. As I have just gone over a few in the last paragraph, there are many different ways this can happen. In chapter 35, the book talks about overload. This is, when an in-flight load exceeds the weight the part was designed for. All structures to include bridges, buildings or airplanes are created to withstand only specific loads. It is unrealistic to assume that airplanes can be designed and built to withstand any conceivable load it can experience. If a structure is exposed to a load greater than which it was designed for, it will structurally fail. Be it deforming, or fracturing into two or more pieces. These are two general reasons why aircraft structures fail. Aircraft structures are designed to withstand loads generated by air at some maximum airspeed and the loads generated while maneuvering at some G load. Most aircraft can be flown at speeds and G loads which can place excessive loads on the aircraft structure. Aircraft that is directly exposed to onrushing air could be damaged as the dynamic pressure of the air stream is converted to static pressure pressing inward on the structure. Excessive speed can reduce the airplanes stability. The bottom line is that a lot of bad things can happen when an aircraft exceeds it’s redline airspeed. One of the clearest reasons for failure of a structural component is that the component lacked the proper strength to withstand the loads created while the aircraft is flown at its normal operating limits. There are numerous reasons why a structural component could be understrength. It is possible that the engineering of the structure was inadequate. The designer could have possibly made an error which was not caught during the testing phase. Another reason could be that wear and tear caused a weakening to the structure. Service life issues are normally divided into four sub areas; fatigue cracking, corrosion, wear and creep. The four of these progressive failures which cannot be undone as the aircraft accumulates flight hours ground-air-ground cycles. An aircraft structure can be weakened in a somewhat short period of time. Exposure to heat can greatly reduce a metals strength. For example, some aluminum alloys that are exposed to temperatures of 400Â ° for 5 minutes can reduce the alloys strength by 80%. Jet engine hot sections and compressor bleed airlines are made of materials such as stainless steel or titanium alloys which maintain most of their strength in relatively high temperatures. This problem happens when structure which is not been designed for high temperature is exposed to high temperatures. Some aircraft which can reach high supersonic speeds require the leading edge structures to be able to withstand the extremely high temperatures generated at these speeds. There are two general areas when it comes to aircraft structures. You have a primary structure, and a secondary structure. The primary structure is parts of the aircraft that are necessary to safely fly its mission. The following components are normally considered to be part of the primary structure: wing structure, fuselage structure carrying flight, ground and cabin pressurization loads, empennage, landing gear structure, engine mounts and supporting structure. The primary structures can be further sub categorized as either critical structure or principal structure elements. Critical elements are those whose failure would result in catastrophic failure of the aircraft. Principal elements are those that contribute significantly to carrying flight, ground and pressurization loads whose failure could or could not result in catastrophic failure. The following components are considered to be the secondary structure: aerodynamic fairings, tail cones, and landing gear doors. There are other mechanical components which carry flight critical loads. Even though these components have failure modes that are closely related to those exhibited by the primary and secondary structures, they do not fall into either of those categories. Components like hydraulic pressure lines, drive shafts, electric alternators, and gear teeth in transmissions all have modes of failure which can give clues concerning the nature of the loads which caused them to fail. In aircraft accident investigator will have a firm understanding of the loads that airplane structured caries and the physical evidence that these loads leaves behind when they fail. The many types of loads are vectors and have both magnitude and direction. You can change the load by either changing its magnitude, for example increasing or decreasing the pounds of force being applied, or by changing its direction by applying force upward instead of down. Loads can take a finite length of time to be imposed. Even though loads can be applied in a very short period of time they can be applied or changed instantaneously. The fact that loads take time to apply and or change is important for the accident investigator understand. The book separates loads into three general areas; static loads, dynamic loads, and repeated loads. Knowing the difference between the three types is important because the nature of the load has a lot to do with the failure of the structure and the evidence left behind. If a load were applied so slowly that the structure to which the load was being applied to stayed equal at all times the load would be considered a static load. A static load can be either for short or long period of time. A dynamic load happens when the loads are applied fast enough to prevent the structure from carrying the load while remaining in equilibrium as the load is being applied. Dynamic loads can be divided into two subcategories, sudden, and impact. A sudden load will impose stronger internal stresses in the structure. Components such as landing gear are tested with dynamic loads. Impact loads are applied at faster rates than sudden, causing the structure to fracture almost every time. Impact loads are usually limited to high-speed bird impacts and crash tests. Repeated loads are just like they sound, loads that are repeated over and over again. Due to the behavior of dynamic impacts and longtime static loads, it makes them unlikely candidates for repeated loads. Short time static and sudden dynamic loads can be repeated over and over again. If a component goes through lots of repeated load cycles before it fails due to fatigue cracking it is said to have experienced high cycle fatigue. By lots of cycles the book means hundreds of thousands or millions or tens of millions of cycles. One of the ways investigators look at structure failure is to consider the time it took for the failure to occur. If the failure happened at the instance of a single load, it is called an instantaneous failure. If the failure took a period of time to occur, that is called a progressive failure. If a structural component contained a load that caused significant distortion, but did not exceed the materials yield stress, and the structure springs back to its original shape after the load is removed is called an elastic deformation/distortion failure. Now if the same events occur and the structure does not spring back to its original shape after the load is removed, that is called plastic deformation/distortion. This is a permanent shape change, unlike the elastic which is a temporary shape change. Now if the load reaches the point where internal stresses not only cause significant plastic deformation, they exceed the materials ultimate stress, the structure will then fracture and separate into two or more pieces. This is called a fracture failure. An experienced investigator can tell the difference between the five different types of structural failure. Another form that causes structural failures is corrosion. Corrosion is the natural disintegration of material as it is attacked by one or more substances in its environment. During the refining process, energy is added to metal ores and other raw materials in order to produce the mechanical properties necessary in structural components. Mother Nature the great equalizer, doesnt like variances in energy levels and sets to work trying to bring the material back to the low energy levels existing in the products of corrosion. When it comes to aircraft structural components, mother natures attack will reduce the strength and ductility of components turning strong metals into meek metallic oxides, hydroxides or sulfates. If these compounds are not removed from the structure they can worsen the problem by providing an environment which is ever more favorable to continued corrosion. There are many different forms of corrosion. Some can be the result of a direct chemical attack by reactive substances in the environment. Pitting is a common form of corrosion. Small holes that are randomly located across the metal surface are called pits and sometimes may be accompanied with a powdery residue. Even though pits may appear to have damaged only a small percentage of the surface, they penetrate deeply in a branching matter causing loss of strength and ductility which is way out of proportion to metals surface appearance. Chemical corrosion involves the reaction between a metal structure and some chemical agent. If you introduce corrosive acid on a metal wing, the acid and the metal will react to form new and undesirable compounds. A selective attack is when corrosive actions seem to favor one part of the components or assembly above another. The primary type of selective attack is intergranular corrosion. This type of attack centers on the grain boundaries with in a metal component before consuming the grains themselves. Similar to pitting the damage from this kind of attack causes a loss of strength and ductility which is out of portion the amount of metal that is corroded. Another form intergranular corrosion is exfoliation, whose progress and go undetected until all structural integrity is lost. Grain boundaries attacked by this type of corrosion are normally flattened and or elongated grains of extruded or rolled metals. This type of corrosion can move undetected along the grain boundaries. Slow removal of material from the surface of the component by a mechanical action is referred to as wear. In most cases wear is undesirable, wear during break in on new or overhauled equipment is often a necessary ingredient in establishing proper operation and long service life. The type of wear the book talks about is the kind that leads to premature failure and breakdown. Abrasive wear happens when small abrasive particles cut into and remove material from surfaces of two components which are held together while moving. When this type of wear happens one question an investigator must ask is, where did the particles come from? Adhesive wear occurs when microscopic projections of the surfaces of the two components which are sliding across each other may contact, weld together and break off. A question that an investigator can ask is was the surface lubricated? Erosive wear is similar to abrasive wear in that foreign particles are cutting tiny chunks out of the surface. Its a little different from abrasive wear in that the abrasive particles gain their penetrating energy by a fluid that is carrying them along. How did the particles enter into the fluids is a question an investigator could pose. To prevent structure failure, the components go through an inspection called non-destructive inspection (NDI). NDI are inspection techniques which will not do significant harm to the object being inspected. Other names for this type of inspection is called non-destructive evaluation (NDE) or non-destructive testing (NDT). There are six specific techniques for these inspections. First, visual inspection is the simplest form and most common of the NDI process and uses your God-given gift of sight. To assist this type of inspection, illumination, magnification, and remote viewing are used to help. Another type is dye penetrant. This inspection is used to detect small surface cracks and discontinuities which may not be visible during strictly visual inspections. This technique is simple, but time-consuming. The component being inspected is covered with a colored liquid which is absorbed into surface cracks. The liquid includes a phosphorescent material which when exposed to ultraviolet light glows in the dark so small surface cracks are visible to the naked eye. Magnetic particle inspection provides another way to assist the eye by increasing the conspicuity of a surface crack. This process requires more specialized equipment then the dye penetrant process, it makes the crack even more obvious if properly used. This inspection makes use of the fact that when a magnetic field is induced in a component made of Ferro-magnetic material, surface cracks will alter the components magnetic field. When magnetic particles are placed on a magnetized surface it will align themselves along the magnetic field showing any variations caused by the cracks. If the magnetic particles are phosphorescent and viewed in a dark room under an ultraviolet light pattern around the cracks will be more visible. Eddy current is the first technique that is discussed that does not require direct viewing of the crack. This process involves the use of a probe to generate both an electromagnetic field and sense and evaluate the Eddy current generated in the material being inspected. When either or surface or near surface cracks are in the material it will alter the shape of the Eddy current and magnetic field it generates. This can be as simple as a twitch on a meters needle. The equipment needed for this type of inspection must be calibrated for the specific design being inspected and the size of the crack being search. Ultrasonic inspections make use of high-frequency sound to find surface and subsurface defects. The high-frequency sound waves are generated by a transducer and then beamed through the part being inspected. The reflective waves or the remnants of waves which penetrate the part are being measured with a receiver and electronically evaluated. There are two different ways the sound waves can be applied to and retrieved from the part being inspected; immersion of the part into a fluid which carries the sound waves to and from the part and direct contact inspection where the transducer and receiver are in direct contact with the part. The direct contact technique is much more mobile allowing use in the field of the aircraft or major fabrications. Radiographic inspection in its simplest form is not much different than that of an x-ray. Very short wave electromagnetic radiation are generated and directed through the part being inspected and towards unexposed radiographic film. Rays passing through cracks, flaws, voids and corroded areas will not be attenuated as much as raise passing through sound material. To the untrained eye, cracks, flaws, voids and corrosion may appear to be just another shadow on the film. Orientation of the x-rays so as to illuminate the discontinuities and proper interpretation of the film are therefore important aspects in ensuring the thoroughness of the inspection. One of the issues which must be addressed in any aircraft accident is a question of crash survivability. Even if no one was injured, the question of what worked and what didnt work should always be asked. Did the restraint systems operate as designed? Whether or not escape hatches were needed, could they have been opened if needed? Did the emergency lighting system work? How crash survival equipment is designed is based on experience, history, and sound engineering judgment. To know if these components work correctly design requires an accident for verification. The accident is a chance to validate our judgment and we cannot afford to pass it up. To make investigation of aircraft crashes a little easier requires a systematic approach by breaking down a complicated series of events into smaller, more digestible bites. The approach chapter 36 goes over is the CREEP method. CREEP stands for: Container, Restraint, Energy absorption, Environment, and Post-crash factors. The first four of the five CREEP elements relate to the dynamic portion of the crash itself. These four factors are concerned with the initial and any subsequent impacts with the terrain, the associated deceleration forces acting on the aircraft and its current occupants, and the deformation and dislocation of aircraft structure and its contents. The fifth factor relates to the occupants attempts to egress the aircraft before suffering additional injuries not directly resulting from the dynamic portion of the crash. In order to survive a crash it is first necessary to provide a living space for the occupants during the dynamic portion of the crash. If the space is crushed or punctured, the chances of survival fall drastically. This factor is container. Now if the occupants have been provided with adequate living space, the next series of questions should deal with the restraint of the crew and its passengers and equipment and components around them. Occupants of any moving vehicle must be protected from injuring collisions with in the vehicle, for example being thrown against the sides of the living space or having objects such as cargo or equipment thrown at them. The strength of all restraints should be sufficient to prevent injury at the force levels which can be expected during the most severe but survivable crash. The investigator should examine all restraints system failures to determine if there failure contributed to injuries experienced by the crew or passengers. The deceleration forces created during a crash may be high enough to cause fatal or serious injuries, even if a safe living space, adequate crew and passenger restraints, and a delethalized flailing envelope are provided. Since crew and passenger bodies are not strongly attached to the airframe, the design of the aircraft structure and seeds may cause the acceleration forces experienced by the crew and passengers to be either amplified or attenuated. A soft deep seat cushion can greatly amplified the vertical Gs experienced by someone sitting in the seat. The deep seat cushion deforms at high loads absorbing energy as it gives can greatly reduce the vertical crash loads to which a seat occupant is subjected. Hopefully, the designers will build a secure box around the crew and passengers and secure them to it. Although we may be able to restrain the torso, it is normally impractical to secure the head and limbs of the crew and passengers. The volume through which the unrestrained extremities can be expected to move shouldve been the legalized to the maximum degree possible. Obstructions which could cause injury should either remove from within the flailing envelope or padded to reduce the severity or probability of injury. This is the environment that the creep method covers. All too commonly, crew or passengers survived the dynamic portion of the crash, only to suffer additional injuries or death when they are unable to safely exit the aircraft in a timely manner. The two primary factors in the causation of fatalities during otherwise survivable crashes is, post-crash fire and inability to quickly exit the damaged aircraft. Fire is the most significant post-crash hazard by a long shot. Not only can the fire kill and injure directly through heat, the toxic fumes and smoke produced when material and the aircraft interior burn are more often the direct cause of death. This post-crash condition is a top priority in controlling to prevent death. Design of airplane exits is predicated on the normal parked attitude and configuration. Obviously, this is not always the case. Sometimes occupants will have to exit from an airplane that is an abnormal attitude and perhaps in a very unusual configuration. Part 125 airplanes have specific emergency exit acquirements levied on them, many general aviation airplanes have only one exit which can be easily jammed in the airplane ends up inverted. In conclusion, nobody is expert on all types of structural failures. With so many different variables, it takes a highly detailed investigator to pinpoint what kind of failure causes a crash. And without a systematic approach of investigation of a crash, the investigators are left with an accident that is difficult to determine whether or not the occupants should have survived the impact.

Human resource management - Essay Example The total construction area is about 590,000 square meters. In line with this, the program has been designed by world-renowned Dutch architect Rem Koolhaas. By constructing the CCTV’s main building, the supporting facilities for television cultural centre and ancillary are improved (Hudong, 2010). With 234 meters high, CCTV’s main building is considered the tallest building in Beijing. From the exterior view, CCTV Tower, the building as a tilt by the two pillars. About 180 meters in the hanging were carried out aerial docking. Its architectural style is elegant. As a single nation-building, it is the largest single building. It is the 2008 Beijing Olympic Games, one of the important facilities. The TV centre includes TV theatre, recording studio, and cultural hotel, press room, digital cinema, large auditorium, exhibition areas, multi-function hall and other facilities. Also it is the television centre during the 2008 Beijing Olympic Games. CCTV is the media agency. It was established from the day will be faced with many stakeholders. And what does stakeholder means here? Stakeholders are an integral part of a project. They are the end-users or clients, the people from whom requirements will be drawn, the people who will influence the design and, ultimately, the people who will reap the benefits of your completed project. It is extremely important to involve stakeholders in all phases of your project for two reasons: Firstly, experience shows that their involvement in the project significantly increases your chances of success by building in a self-correcting feedback loop; Secondly, involving them in your project builds confidence in your product and will greatly ease its acceptance in your target audience (Mariosalexandrou.com, 2010). It is no exception during the Olympic Games in Beijing. Among the stakeholders includes the government regulators, competitors in the same industry, TV stations in various departments w ithin, product advertising, TV
