Own topic - Essay Example How the temperature of the solution influences the enzyme activity. It is expected that the enzyme will be destroyed at high temperatures and will work slowly at low temperatures because the enzyme is found in a plant that lives approximately at 10C-30C. The influence of the pH on enzyme activity. Because the plant tissue that the enzyme is found in is not extremely acidic or basic, it is expected that extremes of pH will have a negative effect on enzyme activity. Previously prepared enzyme extract at volumes of 0.5, 1.0 and 2.0 ml was added to tubes containing 1.0 ml guaicol dye (or 0 ml for control), 2.0 ml H2O2 (or 0 ml for control), and buffer (pH 5) at volumes of 3-5 ml to produce a total volume of 8.0 ml. Spectrophotometer readings at 500 nm were performed at 20 second intervals immediately after mixing the tubes for two minutes and the results were recorded. Mixtures of 4 ml buffer (pH 5) (or 0 ml for control), 2.0 ml H2O2 (or 0 ml for control), 1.0 ml of extract (or 0 ml for control) and 1.0 ml guaicol dye (or 0 ml for control) were combined at a total volume of 8 ml, incubated at 4C, 22C, 32C and 48C and 100C All the solutions were pre-incubated at the appropriate temperatures for 15 minutes to allow them to equilibrate before mixing. Spectrophotometer readings at 500 nm were performed at 20 second intervals immediately after mixing the tubes for two minutes and the results were recorded. To determine the effects of pH mixtures of 4 ml buffer at pH 3, 5, 7 or 9 (or 5 or 0 ml for control), 2.0 ml H2O2 (or 0 ml for control), 1.0 ml of extract (or 0 ml for control) and 1.0 ml guaicol dye (or 0 ml for control) were combined at a total volume of 8 ml. Spectrophotometer readings at 500 nm were performed at 20 second intervals immediately after mixing the tubes for two minutes and the results were recorded To see how inhibitors effect enzyme activity mixtures of 4 ml buffer (pH 5) (or 0 ml

Vietnam War Term Paper Example | Topics and Well Written Essays - 2000 words

Vietnam War - Term Paper Example The former imperialistic Roman Empire should serve as an example of how this cause and effect scenario plays out. A similar destiny awaits America if it refuses to stop repeating the rationalizations for military involvement that kept it in Vietnam for a decade. A result of justifications emanating from Cold War, anti-communism attitudes, Vietnam became the standard by which limitations of the American military can be measured. Following the U.S. victory over the Japanese in 1945, the U.S. and former Soviet Union became engaged in a politically ideological battle that enveloped much of the rest of the world, the Cold War. Communism was clearly America’s adversary and after the Soviets build the Berlin Wall and continued to dominate other Eastern European countries, which became known as ‘satellite’ nations of the Soviets, the U.S. decided to not allow communism to spread into far Southeast Asia for motivations that remain unclear. Though the U.S. used the atomic b omb in Asia less than 20 years earlier, it deployed thousands of troops to the jungles of Vietnam during the decade-long ‘police action’ despite pleas by some that ground troops were necessary only after ‘the bomb’ was dropped in a clean-up role. The fiasco of Vietnam instigated an anti-military response from the majority of American citizens which contributed to the Cold War’s end. ... isolationism at the ending of the 19th century to its status as the sole remaining superpower, has always been centered on the promotion and conservation of its own interests and ‘the advancement of civilization,’ the exercise of power to assert itself beyond the bounds of the American continents in ‘the interest of civilization and of humanity’ and its own selfish interests.† (Olney, 2004) This period of military re-evaluation lasted from the end of the Vietnam War in 1973 until the invasion of Iraq in March of 2003. The U.S. entered the Vietnam conflict to bring democracy to the oppressed indigenous population (the official reason) very optimistic of securing a quick victory. Unsurprisingly, the U.S. went into Vietnam War with somewhat of an arrogant attitude thinking that the North Vietnamese army would soon bow to the mighty American military machine and that South Vietnam would willingly accept and adjust to a westernized style system of governmen t. According to Henry Kissinger, former U.S. Secretary of State under President Nixon, America entered Vietnam with a â€Å"brash confidence in the universal applicability of America’s prescriptions.† (Kissinger,2003) The paradoxical epilogue to Vietnam was that America went into this bloody, horrifying and long-term war believing it would be the noble liberator of the South Vietnamese. The U.S. did this without appreciating the obvious fact that the South Vietnamese people had been fighting for liberation from a North Vietnamese government which represented the same imperialistic way of thinking as the American government. (Ignatieff, 2003) The U.S. failed in Vietnam not because it lacked military capability but because it did not understand the enemy. Although the U.S. marched in with a tremendous military

Effects of Ketamine on the Human Body

Effects of Ketamine on the Human Body The desire to alter consciousness is a fundamental human trait. From being something impossible to finding numerous chemicals in controlling the mind, the process of discovery has also created opportunities for us to explore the effects and mind-tricks behind it. Just like any other new inventions in technology, there is always a path that leads to a wrong destination. The use of psychoactive drugs has turned into a trend amongst the younger generation, endangering both their own lives and the stability of the society. It has been said that this ingenious discover has benefited the forward of our medical industry; yet in our 21st century many have become a tool to escape from stress and reality. These so called party drugs are now produced in large amounts and distributed to young people at bars, nightclubs and house parties around the globe. The disastrous impact behind this irresponsible crime has led to thousands of innocent people condemned and forced to dwell in a living hell. Different people have their own definitions of the term abuse. It is hard to have a universal definition for the word as the bottom line of an individual is drawn upon their own decision. Therefore using the definition published by the World Health Organization, psychoactive substance abuse is defined as a maladaptive pattern of use indicated by continued use despite knowledge of having a persistent or recurrent social, occupational, psychological or physical problem that is caused or exacerbated by the use [or by] recurrent use in situations in which it is physically hazardous.  [1]  In addition, chronic abuse in this context will be defined as a relapsing disease characterized by compulsive drug seeking and use despite harmful consequences as well as neurochemical and molecular changes in the brain.  [2], in other words, chronic abuse is addiction. Addiction is mostly dependent on previously exposed rewards such as food, alcohol, sex, and in this case, on the psychoactive dru g Ketamine. http://www.tjipr.com/images/enji.jpg http://healthimpactnews.com/wp-content/uploads/2011/06/VariousPills-300225.jpg What is Ketamine? Psychoactive Drugs Before answering the above question, it is important to know how ketamine is categorized as a psychoactive drug and its evolvement in human history. The term psychoactive drug is used to describe any chemical substance that affects mood, perception or consciousness as a result of changes in the functioning of the nervous system (brain and spinal cord).  [3]  These drugs are often termed mind-altering because they change the perceptions and the behavior of the individual using them. Psychoactive drugs can be classified into seven different categories: stimulants, depressants, narcotics, cannabis, inhalants, hallucinogens and club drugs. Stimulants are mostly used to relieve tiredness and increase alertness. The most common stimulants are nicotine, which can be found in tobacco products, and caffeine, which is mixed in soft drinks and coffee. The more these drugs are consumed, the more our body will depend on it to maintain the desired effects. Cannabis acts in a similar way, only that it is a plant mainly in forms of marijuana and hashish. Depressants and Narcotics work in the opposite way. They are often used to dull senses and depress the functioning of the central nervous system. These two types of drugs are used medically as anesthetics and analgesics. Small doses of depressants may help more to relax muscles and produce calmness, while larger doses may cause difficulties with reflexes and judgement. Alcohol is a depressant which is widely found in our daily lives, and Narcotics such as opium and heroin are mostly used to relieve pain, yet a long-term dependence on these two may cause addiction and abuse. Hallucinogens and inhalants are synthetic drugs that distort the perception of reality and produce feelings of euphoria. These drugs may cause a short period of excitation and light headedness as it quickly acts on the body as it enters the bloodstream through inhalation. A good example of hallucinogenic drugs is Phencyclidine (PCP), which is mostly used as a sedative in operations before switching to Ketamine. Ketamine is the most common club drug found in the society nowadays. Club drugs have the effect of both stimulants and hallucinogens, and are most popular at party venues such as house parties and nightclubs among the younger generation. Other Club drugs include Ecstasy and Gamma-Hydroxybutryic Acid (GHB). The latter one is odorless and tasteless, therefore gaining the reputation as a date-rape drug as it may cause deep sleep a nd unconsciousness when administered with high dosage.  [4]   Ketamine As mentioned above, Ketamine was used to replace Phencyclidine (PCP) as an anesthetic medicine.  [5]  PCP  was originally tested as a surgical anesthetic in the 1950s.5 It is known as a  dissociative  anesthetic because it can make a person feel a sense of detachment, as if the mind is separated from the body.  [6]  PCP was used in veterinary medicine to anesthetize large animals, but was never approved for use in humans because many patients became agitated, delusional and irrational while recovering from their operations.  During 1960s, PCP was widely abused as it could be easily distributed in pill forms. The powdered form of PCP was developed in 1970s, commonly known as rocket fuel, superweed, etc. which is sprinkled on top of tobacco or marijuana for smoking. PCP  can be easily synthesized; as a result it is often sold off on streets as another drug such as mescaline or Lysergic acid diethylamide (LSD). Due to the worse effects illustrated by patients after the use of PCP, Ketamine was developed in 1962 to replace PCP. It was first known as Cl-581, discovered by scientist Calvin Stevens. Ketamine was then tried in humans as an anesthetic for the first time by Professor Edward Domino, and this is what he said afterwards, Our findings were remarkable! The overall incidence of side effects was about one out of three volunteers. Frank emergence delirium was minimal. Most of our subjects described strange experiences like a feeling of floating in outer space and having no feeling in their arms or legs.   [7]   The successful effects soon encouraged the drug to be patented by the company Parke-Davis for use as an anesthetic in humans and animals. Nonetheless, Professor Domino described Ketamine as a potent psychedelic drug and named it as a dissociative an anesthesia. Ketamine was first used in large quantities in the Vietnam War by the USA Army, where it was used as an anesthesia for soldiers on field. Ketamines chemical structure, mechanism of action and effects are similar to those of PCP, but it acts for a shorter duration and is less potent than PCP. The drug provides dissociative anesthesia, which is a combination of analgesia with superficial sleep. This state is characterized by spontaneous ventilation, relative preservation of airway reflexes and hemodynamic stability, and explains why Ketamine has remained the anesthetic drug of choice in the developing world and for mass casualties in the field.  [8]  Ketamine is tasteless and odorless, so it can be added to food and drinks u ndetected. Because of this, the drug is sometimes used in sexual abuse at entertainment venues and therefore referred to as drug rape. Ketamine is known on the streets as special K, K and cat tranquilizer. Ketamine has plenty of other street names that have changed throughout the years. Originally it was known as rockmesc or mean green  [9]  , and then it evolved to numerous different slang names including Jet, Super K, Vitamin K, New Ecstasy, Honey oil, Mauve, Keller, Bump and Super Acid. Uses and effects of Ketamine exposure in medicine One of the most important happenings in the modern society is our breakthrough in the development of effective medicine for clinical procedures. Advances in technology has prospered the birth of new operation methods such as laparoscopic and robotic surgeries, enabling medical practitioners to increase efficiency to max, at the same time lowering the cost and risk of the procedure. These improvements have greatly ameliorated the side effects of conventional open surgery, allowing patients to heal faster with better comfort. Medicine becomes an indispensable need in our daily lives, and the more it improves, the more we rely on it. I have attended a medical lecture over the summer holidays on the background of surgery. The professor explained the four most important factors behind all the surgeries, namely the 4As: Anesthetics, Analgesics, Antibiotics and Antiseptics. Among these four, Ketamine has already covered two of these factors. Ketamine has several clinically useful properties, including analgesia and less cardiorespiratory depressant effects than other anesthetic agents  [10]  ; in fact it causes some stimulation of the cardiovascular system. Ketamine is soluble in water and is prepared with the sodium salt benzethonium chloride as a preservative. It is a basic compound and is dissolved in a solution of pH 3.5-5. The ketamine molecule contains an asymmetrical carbon atom with two optical isomers (enantiomers). The S (+) isomer is about three times more potent and longer acting as an anesthetic than the R (-) isomer. It is believed that the R (-) isomer is the part of the molecule that is the root o f the cause of some undesirable side effects.  [11]  Studies recently have shown that the S (+) Ketamine isomer is a stronger analgesic with a faster clearance and less side effects than the R (-). It has shown to provide a more rapid motor and sensory block, shorter duration and less motor blockade in elder males.  [12]  Ketamine interacts with N-methyl-D-asparate (NMDA), opioid, monoaminergic, muscarinic receptors and voltage sensitive Ca2+ channels. However, unlike other general anesthetic agents, ketamine does not interact with GABA receptors. The NMDA receptor is a member of the glutamate receptor family. It is an example of an ion channel coupled receptor with excitatory properties which has been implicated in the mechanism of general anesthesia, analgesia and also in neurotoxicity. Ketamine is a non-competitive antagonist of the NMDA receptor which interferes with the action of excitatory amino acids  [13]  . In addition, at clinically relevant concentrations, ket amine interacts with the phencyclidine (PCP) binding site leading to significant inhibition of NMDA receptor activity. This only occurs when the calcium ion channel has been opened. Effects of Ketamine on our body We were always informed with purely the basic consequences of drug abusing. For instance, we were taught that drug abusing may cause serious damage to our body but what exactly is our body suffering from? Central Nervous System Ketamine is the only anesthetic available which has analgesic (pain relieving), hypnotic (sleep producing) and amnesic (short term memory loss) effects. When used correctly it is a very useful and versatile drug.  [14]  Clinically, Ketamine has been reported to produce not only general but also local anesthesia. Ketamines site of action is primarily in the thalamus and limbic systems. It does not suppress respiratory drive unless high doses are used, or smaller doses given rapidly. Unlike other anesthetic agents, patients who have had ketamine may have their eyes opened and make reflex actions during the operation; therefore it is not suitable for use in eye surgeries. However, use of ketamine increases the intracranial pressure, therefore patients who have recent head injuries should avoid using it to prevent further damage. The reason behind was that the rise in mean arterial pressure caused a rise in cerebral perfusion pressure and therefore intracranial pressure. Moreover ket amine is a very effective analgesia and may be used without other analgesics intraoperatively. Due to the frequent occurrence of hallucinations after operation, the patient may be in agitation during recovery. These can be reduced by premedication and by recovering the patient in a quiet area.  [15]   I recently read several medical research papers on the effect of anesthetics and sedatives for the developing brain. A study performed by Dr. John Olneys laboratory demonstrated widespread neuronal degeneration following the repeated administration of ketamine in newborn rats, as well as long-term decreases in neuronal density and impaired neurocognitive function in adulthood following an exposure to other anesthetic drugs.  [16]  It is further discovered that drugs used to provide clinical anesthesia and sedation are thought to affect proper formation of the central nervous system as it interferes the NMDA-type glutamate receptor function. Moreover, several studies have examined the effects of Ketamine on the developing brain of monkeys and have observed widespread neuronal cell death following the administration of multiple doses up to 75mg/kg.  [17]  Another study by Dr. Fredriksson and colleagues demonstrated that a single ketamine exposure of 50mg/kg in new-born mice cau sed abnormal behavior and impaired learning and memory acquisition in adolescence. Experimental data also indicate that NMDA glutamate receptor agonists and GABA receptor antagonists trigger cell death.  [18]   As laboratory investigation on humans is not allowed, scientists may only conduct their research on rats and monkeys. The potential mechanism of anesthetic neurotoxicity is still under investigation; however, it is further complicated by the lack of understanding of exact mechanisms of consciousness and anesthesia. Therefore these results may only be interpreted as a reference to the effects that relate back to ketamine abuse. Respiratory System By using ketamine, the airway is usually well maintained as the airway reflexes and skeletal muscle tone are relatively preserved. Aspiration is a potential hazard despite the retention of protective reflexes. Ketamine is an effective bronchodilator and its action may be mediated either via an increase in blood catecholamine or by its direct smooth muscle relaxant effect.  [19]  When ketamine is given slowly respiration is usually well maintained, after rapid intravenous injection the breathing may stop for a short while but usually restarts within a minute.  [20]  Because of this, ketamine becomes a very useful anesthetic agent in places where there is only limited oxygen available. Cardiovascular System Ketamine is able to increase both blood pressure and heart rate. These variables reach a peak 2-4 minutes after an intravenous injection, then slowly decline to normal values over the next 10-20 minutes. Ketamine produces its cardiovascular effects by stimulating the central sympathetic nervous system and, to a lesser extent, by inhibiting the reuptake of norepinephrine at sympathetic nerve terminals. Individual responses may vary occasionally as there can be a large rise in blood pressure. This risk is not related to a preoperative history of hypertension, but related to the usage of ketamine. This may increase the workload of the heart; hence ketamine should be avoided in those patients with ischemic heart disease. Induced bladder dysfunction Bladder dysfunction associated with ketamine abuse was first voiced out in 2007 by researchers in Canada and Hong Kong. Dr. Shahani and his team presented a series of 9 patients who are all daily ketamine users presented with dysuria, frequency, urgency and frank hematuria. The CT scans revealed a thickened bladder wall, small capacity bladder and perivescicular stranding.  [21]  Dr. Chu and his team presented a series of ten patients with severe bladder dysfunction following regular ketamine abuse. From the statistics of their research, all patients had severe lower urinary tract symptoms and small functional bladder capacity varying from 20 to 200mls.  [22]  A scan of the bladder (cystoscopy) also revealed that the epithelial layer of the bladder has inflammation.  [23]  These reports were from Hong Kong and Canada where ketamine is a popular drug. Dr. Cottrell and his team reported nine patients presenting with similar urinary symptoms and cystoscopy findings following chronic ketamine usage.  [24]  These symptoms are currently left unexplained, but with increasing popularity of the drug in the younger generation, more and more ketamine users could present with ketamine induced bladder dysfunction. As we can see from the above effects, ketamine is already able to induce a lot of problems for our body and affects the whole body system when it responses to the drug in medical uses. Some may be beneficial, but most can cause severe damage to our body, so why is ketamine still on the streets endangering our future generations? Ketamine in our society Back in Hong Kong, I often hear reports from the public media reporting that the police force discovers another drug dealing club/bar with underage drinking and drug abuse. Although we were educated with the basics of the consequences of drug abuse, one simply will not be able to know thoroughly about the essential damage that the drug does to the body. Take smoking as an example: Tobacco has existed for centuries, and people nowadays have beautifully wrapped cigarettes packed in delicate boxes. They can easily gain access to buying one of this highly toxic substance back home for their own enjoyment and pleasure. Putting aside the lack of awareness in the old days, nowadays all the education systems around the globe include the effects of smoking into our classes, no matter taught in Liberal Studies or specifically Biology, most people who have received education are equipped with the basic knowledge of the harmful effects of smoking. Even packages of cigarettes are posted with phot os of the disastrous effects of smoking, for example, a photo of a dissected lung of a chronic smoker, still does not stop smokers from getting on with their habit. In the 1970s, the drug was approved by the FDA to be used clinically on children and adults, yet at the same time it also started to flow into drug markets in public. Most of them were firstly sold by hospital staff; later on it became trendy to produce it in large amounts to divert ketamine into wider population. Over the past 20 years, Ketamine has emerged as a testing replacement for PCP to one of the most popular party drugs at underground parties and raves. In the late 20th century, the drug has already gained its reputation around the globe as one of the mainstream dance culture drugs in society. In the year 1999, The Drug Enforcement Agency in the United Sates made ketamine a schedule three drug. This means that this particular drug is illegal to buy or sell without a prescription.  [25]  Ketamine is considered to be a Class C drug in the UK and Mexico, the equivalent of a schedule three in the United States; and schedule one in Canada. It was legal to possess ketamine in England, Scotland and Wales before 2006. Most countries currently have ketamine under controlled substance act in which it can be used as a medication but not recreationally, for instance ketamine is regulated under Schedule 1 of Hong Kong Chapter 134 of Dangerous Drugs Ordinance. It can only be used legally by health professionals, for university research purposes, or with a physicians prescription.  [26]   Taking the data of ketamine abuse in Hong Kong, in recent years, it has become more common among the teens. In Hong Kong, since 2005 it has become the commonest drug of abuse among persons aged 21 years or less; compared to the first three quarters of 2005, the number of ketamine abusers among teenagers has doubled in the first three quarters of 2008.  [27]  In 2008, ketamine abuse constituted 85% of all kinds of drug abuse among persons aged below 21 years, compared to 61% in 2005. Also, data collected by the Hospital Authority Hong Kong Poison Information Centre (HKPIC) showed that ketamine abusers represented 16% of all drug abusers attending accident and emergency departments in the period of 1 July 2005 to 31 December 2005, while the proportion rose to 40% in the period of 1 January 2008 to 30 June, indicating a steep increase of the number of ketamine abusers.  [28]   Solutions? The reason I decided to put a question mark after this sub topic is because there is no concrete evidence that the treatments I list below will 100% cure the patient. To overcome the psychological dependence on ketamine, the ultimate factor during the process will be the patients endurance and willpower. Without consistency to finish the whole course of treatment is no different to receiving no treatment. Just like antibiotics, you have to finish the whole course in order to fully recover from your illness. We live in an inconsistent and contradictory society. On the bright side, we advise the society not to abuse drugs and say no to the people who sell or offer them to you; yet on the other hand, medical practitioners are encouraging us to take medicine that might cause similar effects and consequences as drugs like ketamine. While we tell young people that ketamine is illegal and dangerous for their health, we ignore to a large extent the bad effects that alcohol has on health, thus making it legal even if it has devastating effects on our body as well. The world has slowly turned into a place where benefits and money take hierarchy over the health of the public. There is an increase in frequent reports of making fake milk powder and eggs, as well as drug manufacturers such as the recent incident of Contergan taking the blame of causing Phocomelia in infants whose parents had taken the medicine. One of the main reasons that ketamine is still one of the most popular party drugs nowaday s is due to the commercial income it brings when it comes to selling and buying. Drug dealing is happening around the globe every day, and what attracts people to do it is not the drug, but the money. Values have been overthrown by the nature of human kind, where selfishness topples conscience in the business world, no matter legal or illegal. Laws and regulations are developed over time to control the extent of these shameful behaviors, yet ultimately there is no thorough solution to this problem. Most societies are uncomfortable with people going off into trance and hallucinatory intoxications, and indeed setting up the laws against the usage and possession of drugs are to discourage people from falling into those in-built worlds of their own. But innate, neuropsychological changes in a persons body cannot be controlled by legislation. Provided that they have the desire to take the drug, they will always be satisfied by themselves. Alcohol may no longer fulfill the need for teenagers to take off from reality into their virtual world of desires after they become fully exposed to it, and slowly they turn to seek stronger effects by trying out drugs like marijuana and ketamine. As they become satisfied with the effects given by the drugs, trying gradually becomes abusing. They start to develop unwise behavior as they reckon that the feeling is brought by the pills rather than from their own nervous systems getting into trouble when the pills no longer work so well. Their drug abuse becomes more frequent and compulsive, yet with less reward. This misconception is the first step to developing drug dependence, no matter whether the drug is marijuana or ketamine or if it produces physiological dependence or not. Dependence on the drug cannot be broken until the misconception is cleared. Drug abusers live on their own reasons to continue, and only those who realize that he/she has been using the drug merely as an excus e for having an experience that is superficial comes to see that the drugged state is not exactly the same with the experience he/she wants. Alternatively, they will start looking for ways that may fulfill the slight desire to lift up from reality, such as meditation and sleeping. If we look in closely to the successful examples of quitting drugs: Many drug abusers give up drugs for consciousness, but little gives up consciousness for drugs. Conclusion We see people travelling through time and going into the mind of others to retrieve thoughts and ideas in fiction and movies, and it is definitely something that I would love to do as well. Yet is it possible to live in dreams and neglect whats really happening in the world we exist in? By altering the state of our consciousness, our brain is simply sending the wrong signal back to ourselves, putting us into a world of our own desires and fantasies. Ketamine can definitely achieve this, but after the short-lived dreams disappear, we will only fall deeper into the K-hole and become more dependent on the drug. We must be clear about the severe effects and consequences that ketamine brings to the individual and the society, and reiterate these problems to the public to prevent further abuse of it. Psychoactive drugs will always be present as a part of our life. The society needs to recognize the problems caused by the misuse of ketamine and deal with them immediately in an open and realistic way. Drug abuse is now connected with other social problems as well, such as social deprivation or family issues. We actually do not know whether the people who abuse it really likes it, but all we need to know is how ketamine can vastly change a persons life when you become addicted to it. From the medical research evidence shown, ketamine can really ruin your life when you are associated with it, yet why blame the drug when it is down to you to choose the reality or to stay in the dreams built by your own desires?

Communicate In A Business Environment Essay

Learning Outcome 1: Understand the purpose of planning communication 1.1 Explain why different communication methods are used in the business environment. Effective communication is vital to the smooth running of a business and various methods of communication are used within a business environment to achieve this. Each form has various benefits to communicate effectively to their designated target audience. When communication is carried out properly it means the sender and receiver both correctly obtain the same information. Each form of communication will be chosen to which is applicable to the situation for example for a one-to-one/ team meeting will be best carried out face-to-face as it is the most effective way to make sure a point is understood properly, as it is a lot more personal and professional. Whereas if a company wants to distribute a monthly newsletter, this wouldn’t need to be as personal as a face to face, it could be carried out over email. Therefore this wouldn’t mean a employee would have to take time out of work and the messages can be sent on a large scale without taking much time to process. Read more:  Identify the different reasons people communicate  essay 1.2 Describe the communication requirements of different audiences. Communication styles need to be adjusted and adapted depending on the target  audience and situation. This is determined by considering which mean of communication is most effective whether it be written or verbal. The various requirements that may need to be catered for include age, gender and ethnicity and special needs. For example, younger people have shorts attention spans, while older people are more patient and are able to sit for longer period of time. Another example is making the visual communication more accessible such as large fonts for partially sighted people. When preparing verbal presentations people with special needs should be considered, such as people who lip read, so they can be positioned appropriately in the room. People with mobility problems such as wheelchair users may require wide aisles for easy access. If arranging group activities you will be required to consider the group of people so that a special needs member can cooperate. 1.3 Explain the importance of using correct grammar, sentence structure, punctuation, spelling and conventions in business communications. a Grammar The aim of having correct grammar is to ensure what is written is correctly understood. A sentence that contains grammatical errors can be difficult to read and can cause misunderstandings. It is important to use correct grammar whether writing or speaking to communicate effectively to help people get a better understanding and to express your communication more precisely and clearly. b Sentence structure It is important to use correct sentence structure in business communications so your writing has variation and isn’t all the same. Using a variety of sentence types can help emphasise different points and ideas. A good sentence structure allows the communication to be correctly interpreted whereas a poor sentence structure can be misinterpreted. c Punctuation It is essential to use correct punctuation to enable the communication to be readable and easy to understand. Punctuation is used in writing to separate sentences and clarify meaning. An error in punctuation can convey an inaccurate meaning to the one intended. d Spelling It is important to use correct spelling in business communications as standardising spelling makes it a lot clearer to understand the text. Incorrect spelling can lead to confusion, mistakes being made and communications being misinterpreted. One misspelled word can change the entire meaning of a sentence giving the reader the wrong message or impression. e Conventions It is important to use conventions in business communications to ensure the writing is in a easier format which the reader will be comfortable with. Conventions are the spelling, punctuation, capitalization, grammar and paragraphing making writing more understandable. This enhances the readability for the audience so they can fluently read the communication without having to stop and try figure out what was actually intended. The use of proper grammar and vocabulary is appropriate in business documents, such as emails and letters, as it is important in a working environment to form a professional respectable relationship with colleagues and customers. If sending an email or letter professionally for business use this would be in a very formal format, whereas if the email was getting sent to a friend the language would be very informal with possibly the use of flag or text talk. The use of conventions always needs to be adjusted depending on the audience, purpose and context. 1.4 Explain the importance of using appropriate body language and tone of voice when communicating verbally. A large part of face-to-face communication is made up of non-verbal  information and is expressed by body language and tone of voice. The tone of your voice includes the volume which you speak, the type of emotion you use and the emphasis placed on the words you use. The same sentence could have various meanings depending on which word is emphasized so it is important to us the appropriate tone when placing emphasis on words to draw the listener’s attention. Doing this incorrectly could mislay the wrong information and impression. Body language portray subconscious messages when communicating. Examples of body language include eye contact, facial expressions, composure and gestures. Body language is recognised instinctively, without having to be told what it means. When relaying messages a lot of the time it isn’t what you say it is how you say it and if your body language contradicts this, the message will not be clear to the audience.

Jasper Jones †to what extent is the novel quintessentially Australian Essay

To what extent is the novel quintessentially Australian? Jasper Jones is an Australian novel by Craig Silvey that explores issues prominent in the author’s 1960s context. Set in the fictional mining town of Corrigan, the novel is a bildungsroman following Charlie Bucktin as he is awakened to the harsh reality of human nature. The novel addresses the main themes of morality, justice and trust, but these universal human issues are coloured by an Australian setting, reflective of Silvey’s contemporary context. The issues of morality and ethics have always been fundamental to the human struggle, but Silvey explores these themes through uniquely Australian concerns, namely the plight of the outcasts, in the treatment of indigenous Australians and immigrants. The setting of the novel, a small town where people are ignorant and bigoted, is representative of the same issues in the wider Australian context. It is made clear to Jasper that â€Å"This town, they think I’m a bloody animal.† due to his half-Aboriginal heritage. The animal metaphor and emotive language highlights Corrigan’s non-tolerance towards racial differences, while the first person perspective depicts the damaging effect this has upon an outcast individual. This is reinforced by the treatment of other characters such as the An family – â€Å"Go back to Hanoi, rats.† The repetition of derogatory animal metaphor and the aggressive tone reveals the prevalent racism. Charlie himself is also bullied for using words that are â€Å"too clever†. Silvey’s portrayal of Corrigan is representative of the morality of his own society. In this racist and anti-intellectual Australian context, outcasts are isolated and beaten down. The theme of justice is closely linked to that of morality; in a town with corrupted values, can justice ever be impartial? Charlie’s moral conflict over whether or not to report Laura Wishart’s body explores the idea of moral relativity. He is aware that â€Å"All that matters is the fact of this girl’s death and the town’s imagination†. The collective town is characterised as an anthropomorphic entity with skewed values; forcing innocent boys to act as if guilty. â€Å"I feel I am caught in a rip, being dragged out further and deeper against my will.† The use of the simile  conveys the boys’ helplessness to enact justice in the face of the â€Å"town’s imagination†. The body itself is a symbol of the novel’s underlying moral dilemmas. In disposing of Laura’s body, Charlie explicitly says that â€Å"I’m committing a crime.† He knows that helping Jasper is the right thing to do, but the use of the word crime, and all it connotes, illustrates how morality can be contrary to traditional justice. The issues of morality and justice explored are unquestionably universal in nature, but the novel’s particular setting and situation renders it a striking commentary on quintessentially Australian concerns. The value of trust and loyalty is also one that is common to all human experience, and it is this that defines Charlie and Jasper’s relationship; which is forged at the beginning of the novel by the crisis of finding Laura’s body. â€Å"Trust me. You got to trust me. Like I trust you.† Jasper’s pleading tone and the repetition of the highly emotive word â€Å"trust†, begging Charlie to help him escape the injustice of being wrongfully persecuted, cements trust as a key value in the novel. With this trust, Charlie is able to look beyond Jasper’s race and form a bond with him, despite the town’s negative stereotyping. He states that â€Å"I am the ally of Jasper Jones†, and helps him despite his conflicted morals. The word â€Å"ally† suggests that despite not knowing Jasper very well, they share a mutual trust and dependence. The relationship between the boys is reminiscent of the loyalty and comradeship between soldiers, bonded by trial. Against the backdrop of the Vietnam War, these values were highly important to the Australian cultural identity in Silvey’s context. Through Charlie’s coming of age, Silvey’s Jasper Jones presents a compelling insight into the duality of morality and the human values of loyalty and justice. Though these are undeniably universal in nature, Silvey explores these issues through the lens of his own Australian context, to give a novel which is quintessentially Australian and yet fundamentally human.

How to Make an Edible Water Bottle

You dont need to wash any dishes if you put your water in an edible water bottle! This is an easy spherification recipe that involves making a gel coating around liquid water. Once you master this simple molecular gastronomy technique, you can apply it to other liquids. Edible Water Bottle Materials The key ingredient for this project is sodium alginate, a natural gelling powder derived from algae. The sodium alginate gels or polymerizes when reacted with calcium. Its a common alternative to gelatin, used in candies and other foods. We have suggested calcium lactate as the calcium source, but you could also use calcium gluconate or food-grade calcium chloride. These ingredients are readily available online. You can also find them in grocery stores that carry ingredients for molecular gastronomy. Materials and equipment: Water1 gram sodium alginate5 grams of calcium lactateLarge bowlSmaller bowlHand mixerSpoon with a rounded bottom (soup spoon or round measuring spoon works great) The size of the spoon determines the size of your water bottle. Use a large spoon for big water blobs. Use a tiny spoon if you want little caviar-sized bubbles. Make an Edible Water Bottle In a small bowl, add 1 gram of sodium alginate to 1 cup of water.Use the hand mixer to make sure the sodium alginate is combined with the water. Let the mixture sit for about 15 minutes to remove any air bubbles. The mixture will turn from a white liquid to a clear mixture.In a large bowl, stir 5 grams of calcium lactate into 4 cups of water. Mix well to dissolve the calcium lactate.Use your rounded spoon to scoop up the sodium alginate solution.Gently drop the sodium alginate solution into the bowl containing the calcium lactate solution. It will immediately form a ball of water in the bowl. You can drop more spoonfuls of sodium alginate solution into the calcium lactate bath. Just be careful the water balls dont touch each other because they would stick together. Let the water balls sit in the calcium lactate solution for 3 minutes. You can gently stir around the calcium lactate solution if you like. (Note: the time determines the thickness of the polymer coating. Use less time for a thinner coating and more time for a thicker coating.)Use a slotted spoon to gently remove each water ball. Place each ball in a bowl of water to stop any further reaction. Now you can remove the edible water bottles and drink them. The inside of each ball is water. The bottle is edible too -- its an algae-based polymer. Using Flavors and Liquids Other Than Water As you might imagine, its possible to color and flavor both the edible coating and the liquid inside the bottle. Its okay to add food coloring to the liquid. You can use flavored beverages rather than water, but its best to avoid acidic drinks because they affect the polymerization reaction. There are special procedures for dealing with acidic beverages.

Paradise Lost By John Milton Essay - 1387 Words

Eve in Paradise Lost In the visions of Western world and civilization, the descend of mankind from the Garden of Eden serves as the prominent, underlying story of the formulation of existence. In 1667, in the seventeenth century, author John Milton recasts the creation story in an epic form of poetry consisting of ten books with over ten thousand lines of verse, in order to conspicuously portray the characters and their actions that lead to the Fall of Mankind. In both Paradise Lost and the Bible, the blame for the banishment of mankind from the Garden of Eden is placed on Eve for falling into the seducing of Satan. Throughout his epic work, Milton conveys Eve s advancement from an autonomous woman to a more reliant woman to portray that women are not essentially conceived as acquiescent beings. Eve is compelled into assent due to the patriarchal environment she is surrounded by, therefore attributing it and allowing her to develop into a women. Paradise Lost conceives Eve as more than solely the mother of humankind and the wife of Adam. Milton s emendation of Eve in a biblical sense alters the character from fixed as portrayed in the Bible to a more dynamic person in Paradise Lost. In doing so, Milton portrays to the reader a different and originally a more favorable perspective of Eve and her character.
