What Is the Infectious Agent free essay sample

For example the name of the bacteria, virus, or parasite. Giardia is protozoan and also flagellated. Flagellated means using appendages in a whip-like movement to propel. Giardia attaches to the host through the lining of the upper intestines. Once it attaches itself, it begins to feed and reproduce causing the giardiasis to commence. Giardia reproduces by dividing itself, which defines it as a trophozoite. This process of division is known as binary fission. Because Giardia reproduces asexually, a single parasite can result in millions within a very short period of time. Giardia detaches from the lining of the intestine and flows down into the fecal stream. The parasite then creates a cyst, which will eventually be released from the body during defecation. This release is known as cyst excretion or â€Å"shedding† and can last for months. The process begins again when another human ingests giardia, and therefore creates another host environment for the parasite.

How is this infectious agent transmitted through food or water? Giardia is most commonly transmitted through water and must be ingested in order to spread the parasite. For giardia to occur, an infected human and or animal would have to somehow spread it from their feces. For instance the reason why we boil water, (not only to make it hot) but to sterilize the water so that there are no parasites of viruses. Giardia can also be received by ingesting even the tiniest amount of contaminated food, water, and even soil. From my understanding you can ingest a cyst without even knowing, for instance when walking into a restaurant we grab the door handle. That surface is so horrifically dirty it’s disgusting. After that the mere gesture of touching your fork tip and then eating with it right after. 3. What is an example of a real life outbreak of this food borne illness in the United States? While you can receive giardia through food, it is more commonly known as more of water borne parasite. Although I did find a real life giardia outbreak that had occurred in New Hampshire year 2007. This incident involved thirty one residents of a very tiny community. The reason why giardia had occurred was due to extremely poor placement of a well. Wells are supposed to be fifteen miles under the ground and this particular well was twelve point five miles under the ground. It may not seem like much of a difference but there are reasons for procedures and regulations. Because someone wanted to cut corners thirty one people had to get very sick and suffer. This was the biggest outbreak of giardia within a community. 4. What are the clinical symptoms, duration of the disease and treatment if any? Clinical symptoms can occur up to two days after giardia has infected you. Giardia, can consist of an over excess of gas, violent diarrhea, nausea, upset stomach, stomach and or abdominal cramps. The first two days you have violent diarrhea, as the infection progresses many people tend to then be constipated for a week or so after along with the very painful production of gas as well as severe stomach and abdominal pain. Giardia can be resolved without treatment. On the other hand there is medication that contains metronidazole and tinidazole, decreases symptoms of giardia. Another thing that can be used is an anti-worm medication. I would assume that it would kill more parasites than worms. 5. What steps can be taken to prevent future out breaks? Include individual as well as environmental precautions and methods. There are many things that can be done to prevent giardia. Most of the things mainly all revolve around very poor hygiene. Ensuring that you are clean is one of the best ways you can avoid giardia. It is always very important to make sure that you wash your hands, especially before touching your face, and mouth. I personally refuse to touch many public surfaces and objects; I always have hand sanitizer on my person. For the environmental part of the question I feel that one of the biggest problems that causes giardia in communities is surface what that is not properly being treated. Out breaks within a community is no fun at all. In my opinion I feel that if everyone were more cautious about their hygiene then maybe there would be very little to no out breaks.

Free Essays on Frederick Douglass

Frederick Douglass In the early 1840’s, Frederick Douglass wrote an autobiography of his life as a slave. His abhorrence of slavery stemmed from two fronts. The first was the reprehensible treatment and dehumanization of the African-American slave. The second was the corrupting influence the power of slavery had upon the slaveholder. â€Å"But, alas! this kind heart [of his mistress] had but a short time to remain such. The fatal poison of irresponsible power was already in her hands, and soon commenced it’s infernal work† (2). In chapters 6-8, Douglass makes one particular point, among many, quite clear: unjust laws corrupt honorable souls and make criminals of law-abiding people. Douglass relates his experience of learning the alphabet from his mistress and the subsequent cessation of this study by his master. Due to his master’s explanation of why his mistress shouldn’t teach him, a slave, to read, Douglass realizes exactly where white society gets its power to enslave black society. That is â€Å"†¦education and slavery were incompatible†¦Ã¢â‚¬  (3 & 6). Upon the heels of this revelation is a second: the pathway from slavery to freedom lies in learning to read (3). The basic injustice of keeping an entire race in mental ignorance for the soul purpose of exploiting them as a work force is one of Douglass’ main criticisms. Douglass conveys to his readers the drastic change that took place in his mistress due to the heady power of having absolute control over another person’s life. She changed from a kind, warm, hard-working soul to a tyrant under slavery’s tutelage (5). Douglass shows his readers just how she went from having â€Å"heavenly qualities† (6) to having the disposition of a tyrant by relating several years of his experiences. His mistress went from teaching him letters to furiously snatching a newspaper out of Douglass’ hand (6), from heavenly smiles to demonic fury (1 & 6), and from t... Free Essays on Frederick Douglass Free Essays on Frederick Douglass Frederick Douglass Born 1818 (?) in Tuckahoe, Maryland Died 1895 in Washington D.C. Frederick Douglass was the leading spokesman of African Americans in the 1800’s. Never knowing his mother or even the identity of his father, he was born a slave and escaped to the north when he was twenty years old. He learned how to read and write in secret, and it became his passion. The abolition of slavery and the fight for equal rights was the subject of all of his speeches, debates and interviews. He founded an antislavery newspaper, wrote several autobiographical books, and helped recruit African Americans for the Union army during the Civil War. His final home was a station along the underground railroad system. Frederick Douglass is one of the most important people in American History. The exact birth-date of Frederick Douglass is unknown, even to him. â€Å"Slaves know as little of their ages as horses know of theirs, and it is the wish of most masters within my knowledge to keep their slaves thus ignorant. I do not remember to have ever met a slave who could tell his birthday† (Douglass 13). Keeping knowledge from their slaves was the masters’ key to dominance. Evidence of a restless spirit within a slave was deemed improper and impertinent, and treated with a trip to the whipping-post. Never the less, Douglass’ careful ear heard his master say, sometime during 1835, that he was about seventeen years old. Sometime during 1818, Harriet Bailey gave birth to Frederick Augustus Washington Bailey in Tuckahoe, Maryland, near Easton. She was the daughter of Isaac and Betsy Bailey, both colored, and quite dark. Frederick’s father, however, was white. Color was the only fact he knew about his father. Whispered opinions claimed that his master was his father, but the truth (or lack thereof) of these rumors was never known. â€Å"†¦true or false, it is of but little consequence to my purpose whilst the fact remains, in all i...

Free Essays on Frederick Douglass Re-Creating One’s Self Frederick Douglass has been an immense role model to all types of people who want to make their lives better. In his biography, Narrative of the Life of Frederick Douglass, he describes his life as a slave, and how he got out of it by â€Å"re-making† himself. Douglass educates himself and re-creates who he is throughout his life; so much so that in the end when he gives his speeches, people cannot believe he was ever a slave. This idea that we can â€Å"re-create† ourselves no matter where we have come from is one that started with Douglass, but is relevant to all humankind. In his opening lines, Douglass addresses how the institution of slavery narrows slaves' opportunities for self-knowledge. Slave owners withhold information about slaves' birth dates in order to keep them from developing a unique sense of self. They do not want their slaves to differentiate themselves from their land or farm animals, as Douglass implies when he says that most slaves know how old they are no more than horses do. Likewise, their masters do not acknowledge family ties among slaves. Family relationships would allow slaves to develop a unique sense of self and would encourage alliances among slaves, a serious threat to the slave owner's hold on power. It was illegal to educate slaves. The enforced institution of illiteracy did the double service of robbing the victim of his voice and of his access to alternative ideas regarding his condition. The slave owner did not want his slaves to know that many Americans saw their bondage as a moral outrage. Nor did he want his slaves to provide first-hand evidence against his prettified picture of slavery, which would give the abolitionists more rhetorical ammunition against him. He wanted to be the center and origin of the "truth" about slavery, both for slaves and for non-slave-owning whites. Despite this unfortunate truth of the times, Douglass found ways to augment his education. So... Free Essays on Frederick Douglass Frederick Douglass was born in Talbot County, Maryland. He does not know the year, as most slaves were not allowed to know their ages. He remembers being unhappy and confused that white children knew their ages, but he was not allowed even to ask his own. He estimates that he was born in or around 1818. â€Å"Frederick Douglass’s mother was Harriet Bailey, the daughter of Isaac and Betsey Bailey. He was separated from his mother immediately after birth, which was a common practice among slave owners.† (biography.com/search/article.jsp?aid=9278324) He assumed that this custom was intended to break the natural bond of affection between mother and child. He also recalled that he only saw his mother on the rare occasions when she could walk twelve miles after dark to lie next to him at night. Harriet died when Frederick was about seven years old. He was told about it afterward and was hardly affected by the news. Bibliography Term Papers, Essays, Book Reports DataBase Câ€Å"Frederick Douglass knew only that his father was a white man, though many people said that his master was his father.† (Frederick Douglass: An American Slave) He explained that slaveholders often impregnated their female slaves. In that era, a law insured that mixed?race children became slaves like their mothers. Slaveholders actually profited from this practice of rape, as it increased the number of slaves they owned. Frederick explained that such mixed?race slaves have a worse lot than other slaves, as the slaveholder’s wife, insulted by their existence, insured that they either suffered constantly or were sold off. He considered that the existence of such a large population of mixed-race slaves contradicted arguments that justified American slavery through the supposed inferiority of the African race. Frederick Douglass’s first master was Captain Anthony. The Captain’s overseer, Mr. Plummer, was a drunk and a cruel man who carrie...

Critically analyse and assess the trend towards globalization of the Assignment

Critically analyse and assess the trend towards globalization of the banking system and its impact on domestic banks. Identify a - Assignment Example The changes include demands from new trends as well as components within the internal organization that are being redefined. Definition of Research Problem The concept of banking is one which is based on national needs, as well as regional elements which are associated with various groups of individuals. However, globalization is beginning to change the internal and external environment while altering products and services offered by those who are a part of banking. This is now leading to several problems, specifically because of the different needs in various parts of the world. Currency exchanges, cost of living relationships, lending channels and basic operations are now being altered, specifically because of needs that are associated with different regions of the globe. The changes are now leading to alterations in market value and many banks which are either making changes domestically or which are becoming dependent on foreign investments and stocks for new opportunities with b anking (Cetorelli, Goldberg, 2008: 14). The research problem defines the problems which are occurring with global transfers as well as how this is redefining the services, products and transfers that are within various banking systems. Literature Review The concept of global banking is one which is now only beginning to surface as a way to work with the corporation of banking systems. In the past, there were basic services and products which were offered specific to the currency of a location. The services and products combined attributes of banking according to one’s culture, capital flows and the financial firms within a specific country. The changes today are now based on an expansion of services and products to help nations in various regions across the world while offering new products and services for changes with global banking. The concept of global banking systems includes the options of lower cost of capital, improved allocation and investments with property rights and institutions. The banking systems are incorporating micro-financing as well as basic services and products which can transfer across borders. Many in other countries are using this as one of the first methods for financing within the country (Mishkin, 2008: 135). The main capabilities for banking systems to establish at a global level come from the enhanced technology which doesn’t define the borders or other applications which are a part of the system. Information processing, telecommunications and other options are providing banks with new alternatives for going overseas. This is combined with the investment opportunities which are continuing to arise for those that are in the different countries. The financial technologies are one of the investments that are leading the way with those who are looking at global expansion from domestic relationships. However, this also limits the products and services which are available and defines a different type of system and sets of services which can be available overseas. Most that are transitioning into this are still experiencing barriers for entry with the government as well as with different needs that are from the technology and the expectations within a given country (Berger, 2007: 1955). Limitations to the Banking System While there are specific aspects that are related to technology, most are finding that this transition is one which is too new to offer complete security

To what extent was Malcolm X a typical American Or To what extent was Essay

To what extent was Malcolm X a typical American Or To what extent was Malcolm X a typical African-American A MUST At lease A- paper - Essay Example ntified himself as a Muslim and black American living in the white American society, there are characteristics that make him both typical American and African-American. Drawing primarily from his autobiography, specifically on the speeches he delivered during the height civil rights activism in the 1960s, this paper discusses the characteristics that make Malcolm X a typical American and African-American. This paper posits that religion is the common denominator found in Malcolm X’s being American and African-American. Malcolm X is a typical American because he subsists to the fundamentalist view of religion and politics: for him, African-American society should seek its own society independent from white American society and guided under the values and teachings of Islam. Malcolm X is also a typical African-American because he confronted his unique experience of oppression by subsisting to religion and faithfully following the teachings and religious principles of Islam. The first position this paper discusses is how Malcolm X became the typical American. As a Muslim fundamentalist, Malcolm X strictly adhered to the teachings of Islam, which includes the belief in establishing an independent society wherein the rules of Islam religion dominate and becomes the socio-political structure of this new, independent society. This is the proposition that has always been advocated by Malcolm X, citing how the religious teachings of Christianity have been used to oppress and take advantage of the African-American society. To demonstrate that the African-Americans always had the right to become independent from the white Americans, Malcolm X argued that the white man had ‘no sense of history.’ In his speech, â€Å"After the Bombing,† Malcolm X asserted that the Negro has a sense of history because all races take root from the Negro heritage—even the white man. From Latin America to Europe, the African-American race dominated the world, until the white

Financial Systems and audits Essay Example | Topics and Well Written Essays - 3000 words

Financial Systems and audits - Essay Example An income statement is composed of several items, including sales, costs, increase and decrease in intangible value, taxes, and outstanding shares. Another key accounting record is the balance sheet. A balance sheet categorizes a company’s resources such as assets, liabilities and owner’s equity. According to Pandey (2002), the components of a balance sheet are divided into current and long-term categories. Pandey (2002) further observes that these components are listed in order of liquidity. Besides a balance sheet and income of statement, a statement of cash flows is also very important in a business. A statement of cash flow provides one with information about a company’s cash receipts and cash payments during a period. According to Khan and Jain (2003), a statement of cash flow has several objectives. Firstly, it is effective in predicting the amounts timing and ascertaining of future cash flows. Secondly, it indicates how cash is used and generated. For thes e reasons, it also helps the creditors, stockholders and customers to determine the flow of cash in a business. Thirdly, it helps an entrepreneur to understand the differences between net income and net cash flow from operating activities. Finally, it helps an entrepreneur to examine a company’s investing activities and financing transactions. 2. Importance of accounting concepts It is important for an entrepreneur to understand different accounting concepts the common of which are business entity, matching concept, money measurement, going concern, accounting period, cost concept, realization concept and accrual concept. To understand the importance of each of these concepts it is instructive to examine their roles. To start with, the business entity treats business and owner as two different entities. In other words, a business entity is the very basis of accounting concepts, conventions and principles. The money measurement concept allows an entrepreneur to distinguish bet ween transactions that can be expressed in terms of money and those that cannot. The going-concern concept assumes a business entity can carry out its activities for an indefinite period of time. This concept is important as it facilitates the preparation of financial statements. The accounting period concept is important in calculating tax, predicting future prospects of a business and helping an entrepreneur to procure credit from financial institutions. The accounting cost concept requires all assets to be recorded in the books of account at their purchase price. This requirement is helpful in the sense that it allows an entrepreneur to calculate depreciation of fixed assets. Another key concept is the dual aspect concept which allows an entrepreneur to detect errors. Another key concept is the realization concept which makes accounting information more objective. Equally important is the accrual concept which helps an entrepreneur to know the actual expenses and income during a particular period of time. In addition, using this concept an entrepreneur should be able to calculate the net profit of his or her business. Finally, there is the matching concept which states that revenue and expenses should be recorded in the same accounting period. This concept should help an entrepreneur to ascertain the exact amount of profit or loss of the business. 3. Factors influencing the structure of accounting systems In order to effectively business it is also important for an

Creativity In The Early Years

Creativity In The Early Years Creativity in an early years setting is difficult to define, although definitions have been provided on the basis of the attempting to define the process of creativity, the product of a persons creativity or the personal attributes that contribute to creativity. Creativity has, for example, been defined as, a novel and appropriate response to an open-ended task (Amabile and Hennessey, 1992) or as very much a processà ¢Ã¢â€š ¬Ã‚ ¦often with no clearly identifiable outcomes or productà ¢Ã¢â€š ¬Ã‚ ¦(allowing children the scope) to explore new possibilities and create new and exciting connections between people, places and thingsà ¢Ã¢â€š ¬Ã‚ ¦to discover meanings in their world (Department for Children, School and Families, 2007). I believe, from my personal point of view, that creativity is actually a mixture of all three of these perspectives: people who have certain attributes are more likely to be able to think, and respond, creatively to certain situations and tasks, via certain processes than people who lack these attributes. Creativity, however, is more than the possession of certain attributes and is certainly not linked to intelligence: it is a factor that individuals can bring to all aspects of their lives, in terms of solving problems in all aspects of their lives in terms of approaching tasks in a creative manner in order to find creative solutions to these tasks, be these artistic endeavors or tasks related to music, mathematics or science. As the Department for Children, School and Families (2007) explain, creativity can transform understanding by fostering critical thinking, allowing children to review, reinvent and make new meanings for themselves. Creativity thus understood defines all aspects of a childs school life, not only traditionally artistic endeavors but also all other disciplines such as mathematics and the sciences: creatively thinking about numbers, for example, can lead children to understand the beauty of mathematics and the fascinating world of physics, which can open their minds to new worlds and new possibilities. Teaching mathematics by rote, seeking only the right answers to set questions will only lead children to hate mathematics classes and to view mathematics as an abstracted idea that is not useful to them, practically, in their lives. Creativity, in this sense, then, can be fostered by encouraging children to explore their surroundings, allowing them to seek their own questions about their surroundings and helping them to arrive at interesting answers for their questions, where interesting answers can be understood as answers that will satisfy them and lead them to further questions. Guiding childrens learning in this manner can encourage creative thinking, giving power to childrens ideas and thoughts, allowing them to creatively solve problems. Allowing children to enjoy the process of thinking, of learning, of researching, can embody creativity in them, in terms of allowing them to develop their own creative responses to their learning experiences and their own creative ways of understanding the world around them. As Amabile and Hennessey (1992) argue, people will be most creative when they feel motivated primarily by the interest, enjoyment, satisfaction and challenges of the work itself rather than by external pressures with such self-directed motivation leading to higher incidences of creativity and self-determined competence. Self-determination, as Amabile and Hennessey (1992) argue, is central to the development of meaningful creativity, i.e., creative thinking that can have real meaning in the lives of children, allowing them to produce creative solutions to all problems they encounter. Creativity can only be fostered, and used in practice to develop meaningful ways of thinking, when three components are present: domain-relevant skills (such as knowledge, experience and talent in a particular domain); creativity-relevant skills (such as independent, flexible, risk-oriented thinking); and task motivation (with intrinsic, not extrinsic motivation being more likely to lead to creative thin king) (Amabile and Hennessey, 1992). As Duffy (2006) argues, the promotion of open-ended thinking, via the use of open-ended activities, can encourage creativity in young children, encouraging the development of creative solutions via experimentation, exploration, discovery and invention. This encouragement of open-ended thinking, argues Duffy (2006) makes learning more meaningful to young children, allowing them, as it does, the scope to develop their own thoughts about themselves, their environment and their relationships, allowing them to develop their own creative responses to the questions that arise for them, from this understanding. Creativity can, thus, argues Duffy (2006) be encouraged and can, through this encouragement, be learned, with its ramifications, as Craft (2002) argues, being lifewide, equipping young children with the tools they need to develop and maintain a positive, open-minded approach to learning. As Prentice (2000) argues, it can be difficult, within the structure of early years education, with its curriculum and its goals that have to be attained, to encourage such creative thinking, in terms of not having the space to foster the conditions most likely to promote creative thought and action. In my experience, classrooms are often not conducive to the fostering of creative thinking, rather being geared towards the attainment of curriculum goals, and right answer dominated thinking, i.e., teaching, and learning, aimed solely at getting the right answer, not at teaching, or, rather, engendering, creative thinking processes. My personal view of the topic is that creativity is a fundamentally important skill to teach to young children in an early years setting, in terms of equipping children with the tools they need to approach all of their subsequent learning and to move in to the world, in order to deal, not only with their academic work, but with all the situations that their life might present to them. Creative thinking, the creative invention of solutions to problems, can better help children to face not only their academic work but also their lives, allowing them to deal creatively with problems they might encounter, equipping them with the tools they need to move positively through their lives. Conclusion Creativity is fundamentally important in the early years setting, equipping children with a whole way of viewing, exploring and understanding their world, allowing them to explore new possibilities in the ways in which they learn. The importance of creativity in the early years setting cannot be underestimated and, in my personal view, more should be done to foster creativity in young children. Although the Early Years Foundation curriculum highlights that childrens creativity must be extended by the provision of support for their curiosity, exploration and playà ¢Ã¢â€š ¬Ã‚ ¦and (children) must be provided with opportunities to explore and share their thoughts, creativity, ideas and feelings (Department for Children, Schools and Families, 2009), recent research, as highlighted in this essay has shown that the forging lifelong, lifewide, creativity in children is a more intrinsic, more involved, more holistic process than simply providing children the opportunity to learn through pla y.

Lab Report: Specific Heat :: essays research papers

Introduction The porpoise of these is to determine the Specific Heat. Also known as Heat Capacity, the specific heat is the amount of the Heat Per Unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature changed is usually expected in the form shown. The relationship does not apply if a phase change is encountered because the heat added or removed during a phase change does not change the temperature. Q = cn^T The molar specific heats of most solids at room temperature and above are nearly constant, in agreement with the Law of Dulong and Petit. At lower temperatures the specific heats drop as quantum processes become significant. The Einstein-Debye model of specific heat describes the low temperature behavior.

Addictions and Phobias Through Classical and Opperant Conditioning Essay

Phobias and Addictions through Classical and Operant Conditioning This paper will explore how phobias and addictions are formed through both classical and operant conditioning and show just as addictions and phobias can be formed, they can also become extinct. Classical conditioning is the use of a conditional stimulus such as a person, place or object that forms an unconditional response. An unconditional response is one that does not require thought, but instead, is a natural reaction of the body (Kowalski & Weston, 2010). Irrational fear of an object or a situation is called a phobia. Phobia’s can make a person become paralyzed with fear for no apparent reason. Phobia’s can be created by putting together an object or a situation with an irrational thought or feeling. Singularly, the object or situation does not provoke a fearful reaction, put once a fearful, irrational thought is associated with the stimulus, the object or the situation creates a fearful response. Phobia’s can be created by classical conditioning. This happe ns when a stimulus is repeatedly paired with a negative reaction. Over time, the brain begins to associate the stimulus with the negative reaction and creates a fight or flight response. Take for example agoraphobia, the fear of being in certain places such as crowds, public transportation or being outside their home without another person. At some point, while doing one of these activities, the individual probably had a panic attack. In his or hers mind, the association between the place and the panic attack has started to take hold. The next time the individual returns to the place or activity, he or she may become worried that he or she will again have a panic attack. The stress from the worry may then elicit another panic attack, which then conditions the brain to have the same fearful reaction to the stimulus. The individual then becomes extremely stressed when faced with the stimulus, or he or she avoids the place or activity completely. This is how agoraphobia is created through classical conditioning. Operant conditioning is a reinforcement of behavior that is controlled by the environment rather than then being a natural  reaction of the body (Kowalski & W eston, 2010). When an individual avoids a situation or an activity because of even the slightest fear, this reinforces the effects and the intensity of the fear. It can become a phobia through operant conditioning. A phobia created by operant conditioning takes place when the negative reaction to the stimulus is reinforced by the avoidance of that stimulus. Over time, the negativity escalates and the individual will have a much harder time dealing with and overcoming his or her fear. While classical and operant conditioning can create phobias, they can also cause addictions. According to the book â€Å"Addictions: A Comprehensive Guidebook† (McCrady & Epstein, 1999) classically conditioned addictions are created when the mind begins to associate a person place or object to the stimulus of the addiction such as shopping, drugs or food. These associations then begin to have a trigger effect and that causes the cravings or urges for the stimulus. With operant conditioning, a person is conditioned to use his or her stimulus of choice because of the feelings or emotions that are aroused due to the use of the individual’s stimulus. These feelings are a positive reinforcement of his or hers behavior directly related to the use of that person’s â€Å"drug† of choice. In the case of an individual who is addicted to food, if he or she is feeling upset or anxious, they may choose to binge on food and in the moment, start to feel less anxious or less irritable. These feelings are a positive reinforcement of their choice to binge. Thus they are conditioning themselves to feel better through the use of food bingeing. This is operant conditioning. Just as classical and operant behaviors are able to take hold, they can also become extinct. In the case of phobia’s or addiction’s, the classical conditioning extinction process starts to take place when the body’s natural reaction, i.e. panic attacks or cravings, start to take place without the person, place or object being posed. Eventually the mind starts to disassociate the original stimulus and the response, leading to the extinction of the classically conditioned behavior. Much in the same way as classical conditioning becomes extinct; operant conditioning begins the extinction process when the reinforcement of the behavior no longer takes place. For the binge eater, if they no longer are comforted by the food, the food starts to become less effectual as a means to control feelings  bringing about the extinction of the addiction (Kowalski & Weston, 2010). Simply put, phobia’s and addictions can be learned and reinforced by way of conditioning and also can be extinguished by lack of the same conditioning. Bibliography Kowalski, R., & Weston, D. (2010).
