Nociception :: Biology Essays Research Papers

Nociception Pain is possibly the most unpleasant sensations our senses can detect. Even though we typically fail to remember what pain feels like when we are not experiencing it, we certainly do not wish to experience pain. Despite pain's unpleasantness, it has to be appreciated for what it is. Namely, a mechanism that allows us to avoid dangerous situations, to prevent further damage, and to promote the healing process. Pain allows us to remove ourselves form dangerous situations, as we attempt to move away from noxious stimuli that cause pain. As we attempt to escape stimuli that cause pain after an initial insult on our body, pain can prevent further damage form occurring. Finally, pain promotes the healing process as we take great care to protect an injured body part form further damage as to minimize the experience of more pain. How is this unpleasant, yet helpful sensation detected? Nociception is the term commonly used to refer to the perception of pain. The receptors involved in pain detection are aptly enough referred to as nociceptors - receptors for noxious stimuli. (1) These nociceptors are free nerve endings that terminate just below the skin as to detect cutaneous pain. Nociceptors are also located in tendons and joints, for detection of somatic pain and in body organs to detect visceral pain. Pain receptors are very numerous in then skin, hence pain detection here is well defined and the source of pain can be easily localized. In tendons, joints, and body organs the pain receptors are fewer. The source of pain therefore is not readily localized. Apparently, the number of nociceptors also influences the duration of the pain felt. Cutaneous pain typically is of short duration, but may be reactivated upon new impacts, while somatic and visceral pain is of longer duration. (2) It is important to note that almost all body tissue is equipped with nociceptors. (1, 2) As explained above, this is an important fact, as pain has primary warning functions. If we did not feel pain and if pain did not impinge on our well-being, we would not seek help when our body aches. Hence, it makes evolutionary sense for the body to be so well equipped with nociceptors in almost all locations. The most notable exception to this logic is the brain. The brain itself has no nociceptors and therefore is pain insensitive. Why is this all-important structure not equipped with and therefore indirectly protected by nociceptors?

How Minority Students Struggle in College Essays -- Personal Narrative

How Minority Students Struggle in College In the lives of minority students, education is seen as essential. It’s a dream, one that we are still trying to interpret. If we know nothing else, we know that education is important because it determines the future one is going to have. The major problem is that the education of minority students before college is poor. This deficiency causes great conflict for minority students in adapting themselves to new educational habits. Lack of good study skills makes it difficult for a minority student to control one’s time management and concentration. While these students are trying to change their study habits, there is another variable that could help or distract them from fixing their weaknesses. It is true that parents and professors do have an influence upon us. These people play a big part in the education of students, but the impact of their persuasion is not always positive. Despite all the struggles that a minority student faces, I believe people in this group can find the secret to becoming educated and successful individuals. Education is exceptionally significant for a minority student. A minority student faces economic issues with his or her lower class status. There is very little money. A minority student comes from a home in which parents have a low level of education. There are not many books around while growing up. A desire to change their economic and cultural position makes education their first priority as a goal they have to reach. Life’s circumstances did not give their parents the chance to go to school. Minority students have seen first-hand how hard it is to live throughout their lives without education. These students believe that if they ed... ...an the upper class students. As a minority student, I advise that we should not let anyone put us down. That is the secret. With or without support, we should keep in mind our goal of becoming professionals in our field of study. If our interest in school is interrupted, we must maintain our deepest reasons for attending college. Looking back and reminding ourselves of our goals will help us to get back on track. College is a race that many of us are competing to win, but we are starting off behind. Minority students should keep on fighting to catch up. It is a complicated battle that consists of personal ambition, educational desire, and inner persistence. If we keep on struggling to become better individuals, we can hopefully someday free ourselves and take off these uneducated and minority labels from our backs and become part of the educated majority.

Essay on The Greater Sin in Hawthornes The Scarlet Letter

The Greater Sin in The Scarlet Letter    In essence, there were three main sins committed in The Scarlet Letter, the sins of Hester, the Reverend Arthur Dimmesdale, and Roger Chillingworth. Roger Chillingworth committed the greatest sin because he let himself be ruled by hatred and the consuming desire for vengeance.   The overpowering vengeance and hatred felt by Chillingworth caused his life to be centered on demeaning Dimmesdale and tormenting him until the end of time.   Both Hester Prynne and Arthur Dimmesdale committed sins for which they were deeply remorseful, Roger Chillingworth, however, committed the greater sin because he felt no guilt.   Unknowingly, Hester Prynne sailed from Europe to the Americas betrayed and tricked.   Waiting for the arrival of her husband, Roger Chillingworth, she lost hope in him ever arriving or even still being alive.   After enduring two years of tortured loneliness and lost love, Hester wished to feel the warmth of love again.   She tried to fill this emptiness by making love with the Reverend Dimmesdale.   When her child Pearl was born, Hester's adulterous sin was discovered and she was cast out from their society and required to wear an embroidered â€Å"A† on her bosom in punishment.   Hester felt guilt for her sin the rest of her life and sought repentance and absolution until the time she died.   Hester never had true love for Chillingworth, but was tricked into marriage.   She later told him this while speaking in her jail cell saying to him, â€Å"... thou knowest that I was frank with thee, I felt no love, nor feigned any† (Hawthorne, page #). Hester was betrayed, tricked and allowed herself to become caught up in the evil desires of another.   She then allowed herself to be trapped by sin, cau... ...me year as a result of this.   Roger Chillingworth's sin was the greatest committed because it ruled his life even until his death. Comparing between the sins of Hester Prynne, the Reverend Arthur Dimmesdale, and Roger Chillingworth, the reader can easily establish that Roger Chillingworth committed the greatest sin.   He did this by being ruled by hatred and the feeling of vengeance.    1.  Ã‚  Ã‚  Ã‚  Ã‚   In your conclusion it would have been good practice to restate the conditions of Prynne and Dimmesdale as well. 2.  Ã‚  Ã‚  Ã‚  Ã‚   Always cite your quote with the name of the author and the page number on which the quote can be found.   For example, a correct citation would be (Hawthorne 60). 3.  Ã‚  Ã‚  Ã‚  Ã‚   Also in quotes, the punctuation should come after the parentheses.   For example, â€Å"My folly and weakness.† (Pg. 52)   should read â€Å"my folly and weakness† (Hawthorne 52).   

Blanche Dubois

Peoples 1 Tashana Peoples Professor Johnson English 201- 9E3 May 18, 2012 Final Research Paper: A Streetcar Named Desire Draft Blanche Dubois is a character in Tennessee William’s play A Streetcar Named Desire. She is a rather important person in the play, as the plot is largely centered on her and Stanley Kowalski. Her character is challenging and controversial because she has a shocking past but portrays herself to be a classy and sophisticated woman. Blanche arrives at her sister Stella’s apartment in New Orleans, Louisiana on a streetcar named Desire (symbol).The urban, somewhat grimy atmosphere is a shock to Blanche. Blanche then starts to look down on her sister’s apartment as well as her husband: Blanche: No, now seriously, putting joking aside. Why didn’t you tell me, why didn’t you write me, honey, why didn’t you let me know? Stella: Tell you what, Blanche? Blanche: Why, that you had to live in these conditions! (Scene One) She acts as if she’s better than everyone else and too good to be living like they are. Even after she insults her sister’s living conditions, Stella still welcomes her sister with open arms.Blanche starts off in the very beginning of the play lying to Stella about her work situation: â€Å"Blanche: I was so exhausted by all I’d been through my- nerves broke. I was on the verge of- lunacy, almost! So Mr. Graves- Mr. Graves is the high school superintendent- he suggested that I take a leave of absence. † (Scene One) Blanche tells Stella that her supervisor allowed her to take time off because of her nerves when in fact she has been fired for having an affair with an underage student. This is just one instance showing her interaction with the opposite gender.Later in the play readers find out that she has also been very promiscuous with numerous men when Stanley receives this information from a colleague. This along with many other things leads to her wanting to esc ape Laurel. Stanley doesn’t like Blanche and he makes it known that he’s onto her lies. In Scene Ten he begins to tell her that she acts classy and has fancy items but not once does that fool him. He even buys her a ticket to go home and tells his wife that Blanche has to leave on Tuesday. Towards the ending of the play, Blanche claims that she received a wire from a man who invited her to go to the Caribbean with him.He is supposedly a wealthy man and she tries to show off by bragging to people about it. Both the wire and the invitation turn out to be another one of her hallucinations. Blanche has had a disturbed life, including a marriage that ended because her husband committed suicide after she discovers him having a homosexual affair. This leads her into a world where fantasies and illusions blend with reality. Everything she tells Stella and Stanley are lies and figments of her imagination. The play ends with her leaving not on a bus back to her hometown, but to a mental hospital with a doctor.

The concentration is dependant on the proportions of hydrochloric acid and water in the solution. The stronger the hydrochloric acid is, the higher the concentration is. I know from my research that other things can affect the rate of reaction, for example:Temperature of acid- the higher the temperature of the acid is, the more energy the particles have to move around, therefore there are more collisions and so a faster rate of reaction. There is a certain amount of energy needed for the particles to react which is called the activation energy, so when the temperature of the solution is h igher, it gives more particles sufficient energy so they move faster to react when they collide more. Size of the particles- when the reactant is a solid then it can be broken down into smaller pieces or into a powder giving it different surface areas.The smaller the pieces, the bigger the surface area is and therefore there is more area for the acid to react with it, and so there is more chance of the particles colliding, so the rate of reaction will increase. Catalysts- this weakens the bonds in the reacting molecules so it seems to lower the activation energy for the reaction. This means that there can be many more successful collisions because particles will have more energy than the activation energy, and so the reaction will be faster. In order to keep my experiment fair, I must keep all the variables the same except concentration, which is what I am investigating.From my preliminarty experiments, I have found that a gas is let off in this reaction and having testing by puttin g it with lime water, I have concluded that the gas is carbon dioxide because the lime water turned cloudy. The equation is: Calcium Carbonate + Hydrochloric acid Calcium Chloride + water + carbon dioxide To find the rate of reaction, I will measure how long it takes to produce a certain amount of gas. To work out the rate of reaction, I have to divide the amount of gas I will collect with the time.Rate= amount of gas collected/ time In order to make this experiment fair, I will keep all the variables the same, except concentration. I will keep the mass of calcium carbonate the same by using one tablet each time. The masses of each tablet vary, but only by a tenth of a gram either side of 1. 01g, which I think is not a large enough difference in mass to make a difference to my experiment. I will try to do all my experiments on the same day, so the room temperature will be the same, which means the temperature of the acid will not change.I will use a burette to measure the amount of hydrochloric acid and water, so the volume of acid will be the same. I will keep the surface area the same because I will use the whole tablet and so each one will have the same surface area because they are all similar in size. Finally, I will use the same apparatus throughout my whole experiment to make it a fair test. I have done preliminary experiments in order to find the amounts I should use for the variables. I chose to collect 40cm? of gas, 50cm? of acid solution and use half a intigestion tablet and crush it.I found three problems with using this half a crushed tablet. The first problem was the fact that it did not react very strongly, and it did not collect more than 24cm? of gas with my lowest concentration of acid, secondly it was difficult to get exactly half a tablet, and this would take too long in my real experiment if I was to get exactly half a tablet each time. Lastly, I did not know when to start my stop clock, because the time delay from the first bits of calciu m carbonate falling into the acid, to the last bits of calcium carbonate falling was quite long and in between this, some gas was lost.This has made me decide to use a whole intigestion tablet, so I do not loose as much gas inbetween putting the tablet into the solution and putting the bung on the conical flask. GRAPH I decided that the lowest concentration I will use is 1M of hydrochloric acid. , which took 85 seconds to collect 40cm? of gas. This highest concentration I will use is 3. 8M of hydrochloric acid, which took 50 seconds to collect 40cm?. From my preliminary experiments I have decided to: Use one whole tablet, 50cm? of different acid concentrations and time how long it takes to collect 40cm? f carbon dioxide gas. My prediction is: The higher the concentration of hydrochloric acid, the quicker the reaction time is with the indigestion tablets. This is because I have found out that the reaction will be quicker as the concentration increases, because the higher the concentr ation is, the more particles of acid there are which are closer together to collide more with each other and therefore react with each other, and so the reaction will be quicker. This is called the collision theory.I will use a graph to show my results, and I know from previous knowledge that the graph should be directly proportional, which means as the concentration increases, so does the rate of reaction. If the concentration is doubled, the rate of reaction is doubled, because there is twice as much possibility for collisions because there are twice as much particles. The line of best fit should go through the origin because when there is no concentration of acid, there are no particles to react. I expect to get a graph which looks like the following:Equipment  · 1 burette containing hydrochloric acid  · 1 burette containing water  · 1 conical flask  · bung and deliver tube  · gas syringe  · stop clock  · clamp stand I am using burettes because they have an accuracy of 0. 1cm? which means I can measure the volumes of water and acid very accurately, and the range of the burette is 0-50cm? of liquid, which is enough for what I need. I will use a gas syring which is accurate to 1cm? of gas collected, and ranges from 0-100cm? of gas which is accurate enough if I am to collect 40cm? of gas.The stop clock is accurate to the 100th of a second, but I will round the time to the nearest second, because it is more realistic when remembering human reaction times, which is about 0. 1 seconds. In order to not let any gas escape, I will make sure I put the delivery tube and gas syring securely together. Method  · Set up apparatus as above  · Take 50cm? of the following concentrations at one time, using the burettes of acid and water-1M, 1. 4M, 1. 8M, 2. 2M, 2. 6M, 3. 0M, 3. 4M, 3. 8M.  · Put the acid solution into a conical flask  · Put 1 intigestion tablet into the the acid and put the bung on. Start the stop clock and time until the marker reaches 40cm?.  · Do this for all the concentrations. I will use a range of 2. 8M of hydrochloric acid, the lowest concentration is 1M and the highest is 3. 8M. I decided to use these concentrations, because in my preliminary experiments, I saw that the reaction was too slow with a concentration below 1M, and that the reaction would be too fast above 3. 8M. I have chosen to do 8 different concentrations, because I will not have enough time to do more, and I will still beable to draw a concusion even if I only use 8 different concentrations.I will have to use both 2M and 4M hydrochloric acid in order to make the different concentrations of acid. The ones which are 2M or below I will make with the 2M hydrochloric acid, and for the rest 4M hydrochloric acid. I will try to use as little of the 4M acid as possible, because it is more dangerous than the 2M. I will take as many repeat readings as I can in the time that I have, because repeats will help me to make sure I do not get any anomalous results. I will reapeat the anomalous results first. The more repeats I do, the more reliable my results will be.Safety I will use 2M and 4M hydrochloric acid which both have IRRITANT warnings so I will be careful using them and try not to get them on my hands or in my eyes. I will use goggles to protect my eyes. GRAPH Results This conclusion supports my prediction well because my results show that the higher the concentration, the quicker the reaction is because there are more particles to react with each other, and so there is more chance for them to collide and therefore the reaction is faster, which is what I originally assumed in my prediction.My graph shows it is directly proportional, because if I take the concentration of 1. 5M of hydrochloric acid, and find the rate of reaction using my graph, it shows that the rate of reaction is 0. 36 cm? /s, and using the graph if I double the concentration to 3M, the rate of reaction is 0. 72 cm? /s which is exactly two times faster tha n the reaction with 1. 5M which shows it is directly proportional. In the following table, I have calculated the average time and rate of reaction for all the different concentrations.I have then worked out the difference between each rate in order to find if there is a trend in how much quicker the reaction is which each concentration. GRAPH From this table, I can see there is a trend, because as the concentration goes up by 0. 4M each time, the rate goes up by 0. 07, 0. 08 or 0. 09 cm? /s which are very close to each other and shows that the rate is quite consistent because no matter what the concentration is, the rate goes up in a certain way on average of 0. 08 cm? /s. The only results that do not go with trend are the 3. M concentrations. On my graph I have circled them as anomalous results. There can be several explanations for this which I will cover in the evaluation. The following diagram is a simple way to help show why the rate of reaction increases with the concentration : My experiment has helped me with my conclusion that the rate of reaction increases as the concentration of the hydrochloric acid increases, and has given me evidence to help explain it. Evaluation My results are as realiable as I could make them using the apparatus and the time I had.From my results I can say that most of the results are quite reliable and accurate to what they should be because I got the results I expected. However, I did get two results which I would say are anomalous. I decided that these two results are anomalous because according to my background knowledge and the rest of my results, I knew that I should get a directly proportional line of best fit, and the rest of the results are very near to this line of best fit. I know that my line of best fit is correct because as the concentration doubles, the rate doubles.The results for the 3. 8M showed that the rate was slower than the rate of reaction with a lower concentration of 3. 4M. There are many different fac tors which may have affected my results. One of the biggest faults in my experiment was the fact that I did not have enough time to complete it in one day. Due to various problems, I had to do the experiment on three different days. This means that all the equipment was different which may mean that they work differently from eachother. This makes it an unfair test.The second problem with doing it on different days is the problem of room temperature which can have a big effect on the rate, because as I know from back ground knowledge, I know the warmer the acid is, the faster the reaction because particles have more energy so there are more successful collisions. I made the mistake of not recording which results are from which day, so I cannot tell if this had a major effect on the results. Whilst doing the experiment, I noticed a few problems which may also have effected my results.First of all is the problem that I only have two hands, so it was difficult to put the tablet in the conical flask, close the bung and also start the stop clock, all at the same time. When there was someone available, I asked them to start my stop clock, but this was not possible all the time. Adding this time to human reaction time of around 0. 1 of a second, some time could have been lost. Some gas was also lost in the time period between putting the tablet in and putting the bung on. I tried my best to make this time period very small, but still some gas was lost.When I had managed to get the tablet into the acid with the bung on and time it, I noticed that sometimes the whole tablet would not go into the acid, and so it was not all reacting, so in order for the whole tablet, I would shake it for a couple of seconds. I did not count how long I would do this for each one, but when I did shake it a lot of gas would be produced, so If I shook one flask for longer, more gas would be produced faster because the whole tablet would be reacting with the acid and there would be more coll isions and therefore a quicker reaction.Between each different concentration, I would wash the conical flask, and I observed that if I washed the flask with hot water, the flask would become hotter, or if I washed it with cold water the opposite would happen. This meant that the temperature of the acid and water solution would vary. This made the tests unfair because if I did some of them with hot conical flasks and others with cold ones, the ones with the warmer flasks would react faster because the temperature of the acid would increase and so give the particles more energy to react.If the equipment was much more sophisticated, for instance if all the equipment would stay the same temperature or if there was special clock which would start at the exact time the tablet touched the acid, my results would be much more accurate, but I still found good results. [IMAGE]If I could do the experiments again, I would do the following things differently in order for my results to be more acc urate.I would make sure I did them all on the same day, use all the same equipment, have someone to start the stopclock, have better equipment, for instance a conical flask with a divider so the acid and calcium carbonate won't mix until I want them to: Apart from all of the problems, my method was suitable and the experiment was successful because I had sufficient evidence to enable myself to come to a conclusion which agreed with my knowledge and prediction. I would have liked to share results with other people who were doing the same experiment as me to see if our results were similar, but nobody was doing the same experiment as me.The only results which I did not think are reliable or accurate is the reaction of the 3. 8M concentration of hydrochloric acid with the calcium carbonate, and if I had more time I would investigate this further. I would find out why these results were anomalous because even though I did reapeats, I still got anomalous results and so I would like to fi nd out why this happened. I would like to investigate the rate of reaction with more concentrations in order to see what happens after 3. 8M acid to see if it was still directly proportional or if the graph leveled off.Other extra investigations I would do would include using different types of acid for instance nitric acid or sulphuric acid and see if they changed the reaction at all. I would also try and use different types of indigestion tablets, because the ones I used contained ginger which I have researched about to find that it is used for digestion, soothing aches and pains in muscles and improves circulation problems, so I would like to investigate if this has a different effect on the rate of the reaction or not.I put an indigestion tablet into 1M of acid concentration and measured the temperature before and after the reaction for one minute to see if the reaction was exothermic or endothermic, but there was no change in temperature, so I would like to see what effect an e xothermic or endothermic reaction would have on the experiment. Overall I think my results are reliable because the repeats are all very close to eachother, the biggest gap between my repeats is the 1. M concentration which had a time difference of 6 seconds, but the others which I had time to repeat are all around 3 seconds apart. If I had more time I would do much more repeats to make my results more reliable. The accuracy of my results are quite good because they are all very close to the line of best fit. I would like to do more experiments and repeats to make sure my line of best fit is accurate and in the correct place. Apart from these I think my investigation was successful.

How Does McEwan Tell the Story in Chapter 9 of ‘Enduring Love’? Essay

Ian McEwan uses a variety of techniques in order to tell the story throughout the novel ‘Enduring Love’. Looking at Chapter 9 in close detail I am going to analyse the ways in which McEwan tells the story with the use of form, structure and language. The majority of the novel is told in the first person however chapter 9 has a third person narrative and is in the present tense. McEwan uses Joe’s narratives in order to explain Clarissa’s perspective. This shifting perspective gives the reader a chance to see Joe from another person’s point of view. By using Clarissa’s perspective, McEwan has created a sense of empathy towards her as Joe is ‘conversationally deaf and blind’ towards her feelings. However it could be argued that this chapter of the novel is more Joe trying to understand Clarissa’s point of view rather than actually telling the story from her perspective, showing the reader only what Joe think she feels other th an what she actually does. Creating an unreliable narrative. Also in chapter 9 the genre is portrayed as more of a romance than a thriller as McEwan uses contemporary romance rather than scientific vocabulary within the narrative, ‘Where’s my kiss? Hug me! Take care of me!’ The use of this romantic narrative takes the novel away from the typical thriller genre in order to tell the story. Although chapter 9 is shown to be of a romantic genre, it still includes conventions which McEwan uses to suggest that the novel is a psychological thriller. The use of a relationship breakdown within this chapter gives the reader this idea. As well as this, towards the end of the chapter the reader is reminded of Joe’s stalker, ‘he sees Parry waiting for him at the end of the brick path he does not even break his stride’ The fact that Jed Parry is waiting at the end of the road for Joe also brings back the idea of a psychological thriller genre. McEwan uses the pace within this chapter in order to effectively tell the story, at the beginning the pace of the narrative is slow, Clarissa is tired and the use of sentences and description suggest that she is calm. It isn’t until the argument breaks out between Joe and Clarissa that the pace begins to pick up. This increased pace within the narrative shows the anger and frustration within Clarissa and is the first sign of the relationship breakdown. Throughout the chapter McEwan shows a sense of frustrated within Clarissa, ‘She stands in the bath and snatches a towel to cover herself’, the idea of ‘snatching’ seems out of character for Clarissa and helps to portray her anger towards Joe and his growing obsession with the accident and the idea that Parry is stalking him. Furthermore, McEwan uses figurative language in order to tell the story, ‘he’s raising his voice over the thunder of the taps’, this use of language could be seen to foreshadow the thunderous argument with is later going to happen between Joe and Clarissa. The irritation within Clarissa is presented in this chapter through the use of figurative language, ‘Joe is hanging in the frame of the bathroom door like some newly discovered non-stop talking ape. Talking, but barely self aware’ Using this quote within the narrative shows how much Joe is getting on Clarissa’s nerves, supporting the idea of a relationship breakdown. The fact that Joe won’t stop talking while she’s trying to relax builds tension within the narrative as Clarissa’s frustration begins to increase suggesting that an argument is about to happen. Throughout chapter 9, Clarissa presents the idea that Joe may not be sane as she discards his claims about Jed Parry, ‘you were so intense about him as soon as you met him. It’s like you invented him’ she suggests to the reader that Joe is imagining everything to do with Jed and the idea that he is stalking him, Clarissa believes that it is just an effect after the traum a of the balloon accident, leaving Joe unstable and ill. McEwan uses this to give the reader another perspective of Joe’s claims as until now we only see the idea that Jed is following Joe. Within this chapter of the novel, the reader becomes aware that Joe is in turn becoming obsessed with Jed, ‘you ought to be asking yourself which way this fixation runs’ Clarissa suggests Joe’s obsession at the same time as discarding this claims about Jed. However at the very end of the chapter we see that Jed is waiting for Joe at the end of the road, reassuring the reader of the reality of the stalker and giving the conventions of a psychological thriller. McEwans use of Jed in this chapter is important as it gives the reader an element of trust within it’s narrator as they begin to believe Joe’s perspective over Clarissa’s.

Taxes working to raise the economic efficiencies when the exploitation of economic resources and guidance these resources to better use and to achieve social justice in the distribution of income and achieve economic stability where justice is no longer only socially, but became a vital requirement in achieving national security in the community as well. Thus the state with individuals involved in achieving these goals and to achieve security inside and outside, but some taxpayers, and who want to provide services directly in the performance of their pay tax, as expected consumer benefit directly from having to purchase a good or service ignored , so the nature of the relationship between the state (IRS) and citizens (in charge) and they get rid of the legal obligation to pay their taxes partially or completely and using a number of methods and techniques fraudulent by refraining from paid the public treasury, and that means tax fraud . So we look at this study the issue of evasion in value added tax and known shortened VAT, and is a general tax levied on businesses that produce and distribute goods and services, and is the VAT tax on consumption because Stoic final it is the consumer, despite the fact that collected is the producer or distributor. Where the subject will be studied theoretically and problem will be identified and the objectives and methodology and the study sample. Objectives study This study aims to achieve the following objectives : – Get free professions and trades that are subject to VAT. – study the legal texts of the relevant laws in liberal professions and link them to the collection tax . – Get nature and forms of evasion in VAT the self-employed . – Get the underlying causes of evasion in VAT the self-employed .. – Develop appropriate mechanism to deal with tax evasion to the self-employed . Problem Statement Is the increase of the rate of value added tax (VAT), the nature of the political system and double taxation would lead to VAT fraud ?! The relevance of the study The importance of this study lies in the need to educate self-employed seriousness evasion in vat and the consequent negative effects on the financial activity of the State, and comes through definition of this category duties tax and rid them of the issue of inheritance Social which prevailed between groups of Palestinian society, including self-employed before the advent of the Palestinian Authority, where he was in charge of the Palestinian is evasion of taxes national action, because the tax revenue goes to illicit destinations . Literature review According to Smith and Stephen (2007) ,they resorted to some of european experiences of European countries. This study aimed to reviews what is known about the exposure of the VAT to revenue losses through noncompliance, with a particular focus on fraud and evasion,and considers what can be done in respons. And they are follow the methodology to eliminate fraud in the VAT, by used More radical measures within the context of a system that preserves zero-rating include , The use of ‘reverse charging’, by which liability in a business-to-business (B2B) transaction is placed on the buyer rather than the seller. This would deal effectively with the carousel fraud, and by ending the gradual cumulation of VAT payments through various stages of production and distribution and instead collecting all VAT revenue at the final sale, the system is exposed to substantially greater risks of revenue loss through unreported sales to final consumers , With a retail sales tax all tax revenue is lost if a sale to final consumers somehow goes unreported, while with a VAT the losses are limited to the difference between the VAT due on the final sale and the VAT already collected at earlier stages. Smith said that have argued that a longer-run and durable solution to the problem of missing trader fraud requires a fundamental redesign of the VAT treatment of international transactions and this Systematic reform that eliminates the root cause of missing trader fraud would be a much more appealing long-term strategy than the combination of resource-intensive enforcement operations and ad hoc ‘fixes’ such as extended reverse charging, which may provide temporary relief. The study of Richard(2011) , focused on a technological methods in the fight against tax fraud.This study aimed to fighting tax fraud (vat) bye using a technological method of this . So there is a three leading technology-based solutions will be considered here: the Real Time VAT (RTvat ) the VAT Locator Number ( VLN) system and the Digital VAT (D-VAT), There are important differences among them, but generally, the RTvat focuses on securing the tax, the VLN focuses on securely tracing the supply, and the D-VAT certifies that the correct tax is charged collected, and remitted. Richard have reached some conclusions based on technological solutions developed that The RTvat is applied to all transactions in a VAT system. It changes the underpinnings of the VAT, moving it from an invoice system to a settlement system. The withholdingand-remit element of a VATsystem has been effectively removed and VLN also applies to all transactions in a VAT system but leaves the basic structure of the V AT untouched. It simply adds an encrypted tracer code to every invoice. As Borselli’s stydy that aimed to firstly, it outlines the fraudulent VAT schemes that pose the most serious threat to the functioning of the VAT system, and evaluates the effectiveness of the strategies adopted to combat and prevent that type of fraud. Secondly, it comments on the costs and benefits of more far-reaching measures to be implemented in the near future at EU and national level.He follow the mechanisms that fighting taxation fraud as , A hybrid reverse charge mechanism would also give rise to other issues. Firstly, it would lead to a substantial increase of VAT refund claims by taxable persons, who pay VAT to their suppliers (on their inputs not exceeding the threshold value), where their output transactions are subject to the reverse charge mechanism. Secondly, treating identical transactions differently for VAT purposes reduces the effectiveness, of anti-fraud measures , increases the complexity of the management of the VAT system and requires a tough control system in order to protect Member States from adverse effects. Where it was concluded that the need to maximize the effectiveness of the strategy to combat VAT fraud cannot be separated from a broad view on the functioning of the VAT system as a whole. Available mechanisms interact, require a high degree of adaptation to the economic and legal context and must be a constant of the Member States’ regulatory framework. This means that there is not asingle road† to a more efficient VAT system and that it is inappropriate for Member States to simply copy and transpose the measures taken by other Member States into their national legislation. In 2011 , Kaspar Lind , faocused in his aticls on the issues of ï ¬  scal fraud, closing of transactions, and good faith , and to analyse Estonian legislation and the practice of the Supreme Court and its development in the past 10 years, and to compare it to the practice of the European Court of Justice. Given that fiscal frauds are a serious problem, According to that , the payment for goods or services would take place through the bank, and the bank would divide the payment into two parts (the price of the goods or services and the amount of tax), of which the amount of VAT would be paid directly to the tax authority. With the second scheme, a central database is created for invoices taxed with VAT that the tax authority can monitor in real time. Thirdly, separate VAT databases are used that are very easy for the tax authority to access in order to check invoices. Certiï ¬ cation is seen as a fourth solution. Aside from the reverse charge, the ï ¬ rst solution is considered the most effective;however, it would require a substantial transformation of the existing system. The other three models might improve supervision but do not directly ensure a better receipt of taxes. He said † Although they can draw general conclusions on how to act with regard to the VAT system, due diligence may depend greatly on each country’s legal order and practice. As a result, it is very difï ¬ cult for entrepreneurs to operate in different European Union Member States. Often entrepreneurs can learn of the exact content of their due diligence only in the course of judicial proceedings, but that might entail tax liability† In recent years ,The European Union’s VAT system has become vulnerable to organised fraud schemes , so there is an schemes studied by Fabrizio Borselli. This article shows that need to maximise the effectiveness of anti-VAT-fraud strategy cannot be separated from a broad view of the problem and of the functioning of the VAT system as a whole. A drastic change in the VAT system might provide a robust defence against fraud but produce uncertain effects. The study showed the most important policies established by the member states to fight fraud by developing early-warning systems for sectors and transactions at risk. Since missing traders need to enter the market before committing the fraud (i.e. to obtain a VAT identification number, unless they hijack another trader’s VAT number), a sound system of preventive risk analysis is essential for effective antifraud action. Many EU Member States use advanced software for risk analysis and electronic databases containing macro and micro data on traders, including the economic sector in which they operate, their financial situation and ownership, their payments, declarations and refunds of VAT . As pointed Bouresli that Policy initiatives could be initially limited to certain sectors and companies, with wider structural measures implemented afterwards, taking advantage of further developments in IT and harmonisation of the EU legal framework. New types of fraud are technology-intensive: technology itself appears to offer some of the best answers. According to Dr. Konstantin Pashev (2006) , Adopted the Bulgarian experience in identifying the types and modus operandi of VAT frauds with a focus on the abuse of tax credit. It analyses the elements of tax design permissive of such abuses and discusses the possible solutions in the light of the international and domestic experience and the capacity of the tax administration , Where indicated dr. Pashev the mechanics of organized fraud by fictitious export and the missing (insolvent) trader fraud. In the case of fake exports, the exporter carries the transaction on paper, applying the zero VAT rate on exports and claiming tax credit on the inputs, while actually selling the products on the domestic market without sales invoices, i.e. without paying VAT. A safer version would use real exports, but would overstate the quantities exported . The study concludes that the possible solutions should be sought along the lines of optimizing risk management and the principle of joint liability rather than through tighter controls at entry and on the conduct of business. the theoretical framework and methodology of the study : VAT(Value-Added Tax) is a tax that’s charged on most goods and services that VAT-registered businesses provide in the UK. It’s also charged on goods and some services that are imported from countries outside. Whereas VAT fraud is a scheme through which businesses avoid paying VAT and even claim refunds for VAT they never pay. Such businesses actualize their criminal intents using different established methods. Thus, different types of VAT fraud can be identified, which governments of VAT-administering countries have spent huge amounts of money to investigate and checkmate. review by looking at the literature review of the value-added tax in particular and some of the variables that affect them in general, including income tax, inflation, and the nature of the political system in the country. Since each variable has a direct relationship in its impact on the value-added tax. Independent Variables :- Inflation Rate of income The natural of political system Dependent Variable VAT Fraud In economics, inflation is a rise in the general level of prices of goods and services in an economy over a period of time , When the general price level rises, each unit of currency buys fewer goods and services. Consequently, inflation also reflects an erosion in the purchasing power of money – a loss of real value in the internal medium of exchange and unit of account within the economy as the inï ¬â€šation rate rises, the money demand becomes increasingly interest elasticity, as in Cagan’s model, and credit is increasingly used to avoid inï ¬â€šation, instead of using leisure; this implies that velocity rises at a faster rate, and the growth rate falls at a decreasing rate. Politics system tells you how a society must be set up and how one should act within a society. Except for hermits, this comes up a lot. As for the relationship between the nature of the political system and tax fraud interpreted as the lack of confidence in public spending policy , no doubt that the way to spend the proceed of tax impact on the psyche of financiers overhead costs, as if mony spend in the faces of the benefit of binding it feels comfortable and reassuring , he may give tax willingly , Which makes the system vulnerable to deception and fraud . As for the rate of income is defined as follows , a tax that governments impose on financial income generated by all entities within their jurisdiction. By law, businesses and individuals must file an income tax return every year to determine whether they owe any taxes or are eligible for a tax refund. Income tax is a key source of funds that the government uses to fund its activities and serve the public. Hypotheses There’s a relationship between VAT fraud and inflation .   Since there is a relationship between the level of income and tax fraud. There is a relationship between the political system and investors went to tax evasion, as it depends on the policies directed by the state. The population and the sample of the study Since I will talk about the VAT fraud in private sector, the population is the Palestinian private sector companies, and the study sample will be a number of these companies. Data collection The data were collected from two resources of data: Secondary data* Which is the data that developed for the purpose other than helping to solve the problem on hand? Some of these data are books, journals, articles, website, and internet it’s considered as a useful sources of information for historical background, and theoretical framework. Primary data* Among the choices for collecting the primary data such as: observations, survey questionnaires, and interviews .Taking into account the research problem the survey questionnaire is the best alternative for this research .
