Are There Black People With Freckles

Are There Black People With Freckles SAT / ACT Prep Online Guides and Tips When you think about freckles, what do you think of? Fair-skinned children whose mothers slather sunblock on them? Bright, shocking red hair? Maybe even Pippi Longstocking? As a beauty feature, freckles are commonly associated with fair-skinned people, leading to the question: â€Å"Can black people have freckles?† The answer is yes- there are many black people with freckles, as well as people with other skin tones who have freckles, too. In this article, I’ll break down what causes freckles and who has them. I’ll also provide images of black people with freckles to demonstrate the different skin tones that have freckles. Can Black People Have Freckles? 3 Examples of Freckles on a Black Person Check out these three images to see examples of how freckles look on a black person. What Are Freckles? Freckles, also known as ephelides, are clusters of melanized skin. Freckles have melanocytes (melanin-producing cells) that overproduce melanin granules which change the color of outer skin cells. What does that mean? Basically, freckles are bunched-up clusters of melanin-producing cells. When UV rays hit these bunched-up clusters of cells, they’ll darken in color, changing the pigment of small parts of your skin. Freckles are triggered by sunlight, meaning that they develop as you grow and expose your skin to the sun. Because freckles appear after exposure to sun, many people associate them with sun damage. However, freckles are actually not related to sun damage at all. Freckles can, though, disguise lentigo, or sun spots, which can be a sign of cancer. Regardless of your skin tone and the presence of freckles, you should always protect your skin with a broad spectrum UVA/UVB sunscreen that’s SPF 30 or higher. Not just anyone can have freckles. In order to have freckles, you must have a variation of the MC1R gene. People of all heritages and skin tones can have this genetic mutation. Why Are Freckles More Commonly Associated With Fair Skin? If there are black people with freckles, why are freckles so predominantly associated with people with fair skin? Why aren't there many examples of black people with freckles? The answer lies in genetics. The variation of the MC1R gene that causes freckles is passed down genetically. People of Celtic heritage, who typically have very fair hair and skin, are more likely to have this genetic mutation than other groups. However, people of African, Mediterranean, Asian, and Hispanic descent can also have freckles. The genetic mutation simply isn’t as common in these groups as it is in groups of Celtic descent, so you don't see as many Asian or black people with freckles. Can Freckles Disappear? Just as freckles appear in the light, they can fade in the lack of sun exposure. Many people whose freckles appear during the summer often watch those same freckles fade over the winter. On the other hand, there are plenty of people whose freckles stay year-round after they first appear. Every person’s freckles are slightly different. 4 Tips for Taking Care of Skin with Freckles While freckles aren’t associated with skin damage, they can make you more prone to getting other, malignant types of skin conditions. Follow these four tips to take care of your skin if you have freckles. #1: Always Wear Sunscreen Both fair skinned and black people with freckles (and really everyone) should always wear sunscreen. Look for a broad spectrum UVA/UVB sunscreen that’s SPF 30 or higher. If you’re trying to limit the appearance of freckles, sunscreen will help guard your skin from the UV rays that cause freckles to appear. Sunscreen will also help prevent dangerous skin damage. #2: Visit a Dermatologist If you freckle easily, your skin will also be more prone to skin cancer and sun damage. You should visit a dermatologist at least once a year to receive a skin cancer screening. Some types of skin cancer look like freckles, so it’s important to visit a doctor who can help you tell the difference. #3: Perform Monthly Self-Examinations Just like women should perform monthly breast self exams, people with freckles should perform monthly skin exams. You don’t have to do anything fancy for a skin exam- simply make note of the freckles, moles, and other skin markings you have. The more aware you are of your body, the more likely you are to notice when something has appeared or changed. #4: Exfoliate Exfoliating helps remove dead skin cells and allows for healthy skin turnover. Exfoliating will help remove dead, dull-looking skin and help your other skin care products, like sunscreen and moisturizers, work better. Recap: Can Black People Have Freckles? Freckles are caused by a variation on the MC1R gene- and anyone, with any skin color or heritage, can have them. Freckles are clusters of melanin-producing cells that appear when exposed to UV rays. If you have freckles, it’s important to take good care of your skin by using sunscreen to prevent from sun damage.

Real, Not Monetary Shocks Drive Business Cycles †Business Essay

Real, Not Monetary Shocks Drive Business Cycles – Business Essay Free Online Research Papers Real, Not Monetary Shocks Drive Business Cycles Business Essay A business, or trade cycle, is the term used to describe the tendency for recurring fluctuations in economic activity characterized by alternating periods of upward and downward movements in the aggregate level of output and employment, relative to their long-term trends. The initial concept of business cycles is generally attributed to French physician Clement Juglar, who described the economic cycle in 1860 as ‘a recurring, if not necessarily uniform pattern.’ Since that time, a four-phase scheme has been used to describe fluctuations in business cycles: an upturn ends at an upper turning point (boom), followed by a downturn which leads to a lower turning point (recession) which is, in turn, followed by the next upturn (Fig. 1.1). Theories on the causes of business cycles have considered an array of possible factors yet neither theoretical nor empirical work has conclusively delineated the underlying causes for fluctuations. I intend to expound the theories and assess relevant evidence on behalf of both real and monetary shocks. I turn, I shall also comment on how the two schools of thought are implicitly tied to political po licy and finally offer an answer as to which really drives business cycles. Mainstream macroeconomists view recessions as a case of market failure. There are workers who would like to work but cannot because no one is willing to hire them. Their lack of income creates consumers who would like to spend but who cannot because they do not have the funds to do so. As a result, there are businesses that would like to produce and hire more workers, but cannot because there is not enough demand for final output. The circle is complete, and there is something not working properly. The traditional explanation for this situation was a failure of wages and prices to adjust quickly enough. A change in spending drives the economy away from equilibrium, but sticky wages and/or prices prevent rapid adjustment to a new equilibrium. Real-business cycle theorists reject the above explanation based on the assumption that markets always clear. Hence wages and prices should not be sticky, but should adjust quickly. In essence, the central idea is that technical change is the most important kind of economic disturbance behind business fluctuations. This approach builds on the ideas of Joseph Schumpeter who held that capitalism is characterised by waves of â€Å"creative destruction† in which the continuous introduction of new technologies constantly drives existing firms our of business. When there is a temporary improvement in technology, this temporarily raises productivity. It follows that the real wage is also temporarily higher given that workers are paid their marginal product, which is equal to the real wage. Workers respond to the temporarily high wage rate by deciding to work harder while the real wage is high, and as a consequence, output rises. Suppose that in some weeks you get paid $15 per hour, and in other weeks you only get paid $5 per hour. If one could choose how many hours a week to work, what kind of pattern would be expected? Though some people may choose to work the same in all weeks, most people would work longer in the higher-pay weeks and less in the lower-pay weeks. They will take their leisure in the lower-pay periods, and move their work to the higher pay periods. The real-business cycle suggests that this same pattern holds over longer periods. When there is a technological shock raising real wage, people will work more causing output to surge, and when there is a technological shock lowering real wage, people will withdraw from work, causing output to fall. This pattern is what we observe as booms and recessions. Clearly, real business cycle theory depends heavily on the ability of workers to alter the amount of labour and leisure time they choose at each point in time. This is called the inter-te mporal substitution of labour, and it is one of the most controversial assumptions of real business cycles. Many economists find the real-business cycle theory totally unbelievable. No one can observe the technological shocks that are at the heart of this explanation, and it strikes many as simply ridiculous to argue that the unemployment during a recession is voluntary. However, the evidence for the argument that real shocks drive business cycles may be found in cases of natural and artificial disasters. Natural disasters such as the tsunami in Asia and artificial disasters such as the terrorists attacks on September 11th 2001. The evidence that September 11th caused an immediate and continued downturn in the economy of the United States (and as a direct result the strength of the dollar) is undeniable. Likewise the economic effects on the affected areas in Asia are possibly even more extreme. Entire villages and towns have been entirely destroyed and consequently the economy is defunct. Herein lies the problem of talking about business cycles in general. It is clear from the exampl es above that a business cycle in the developed world means a very different thing to those countries in the early stages of economic advancement. However, both cases support the argument that real shocks are the primary force behind business cycles. In terms of policy implications real business cycle theorists are inclined to deny the powers of governments, through monetary and fiscal policy, to control the rate of economic growth. In contrast those who believe that monetary shocks drive business cycles argue that it is indeed the government (or central bank) policies that can control the rate of growth. The target of monetary policy may be the achievement of a desired level or rate of growth in real activity, the price level, the exchange rate, or the balance of payments. In both the UK and the US policies have included setting the interest rate charged by the central bank, sales or purchases of securities to control the money supply, and changes in the required reserve ratios of banks and other financial institutions. Monetarism was drafted as a ‘revolution’ against the then orthodox Keynesian theory. In the early and mid-1960s, monetarism and Keynesian economics were regarded as distinct and probably irreconcilable explanations for business cycles. Monetarists distinguish themselves from other economists by stressing the existence of a stable money-demand function. One implication is that the best way to stabilise the economy is to stabilise the rate of growth of the money supply at a low level. Assuming that output is determined exogenously (by the microeconomic supply decisions of households and businesses) so that Q can be taken as given, then the definition of velocity implies: P = (M .V)/Q If V is fairly stable, and Q is exogenous, the equation implies that changes in M translate into changes in the price level. Thus, monetarists stress that changes in M are the key to controlling the price level. They hold that money should be allowed to rise at a constant rate per year. Thus, controlling inflation becomes merely a problem of controlling M. Monetarism is much more sceptical than Keynesian economics with regard to the need for, and efficacy of, stabilization policies. In order not to distort price signals, the government should make the supply of money stable and predictable. An independent central bank is helpful in achieving this goal. Friedman and Schwartz brought money back to the fore with the publication of their Monetary History of the U.S (1963). In this influential book, Friedman and Schwartz show that money and real aggregate production move together closely over the business cycle. Laidler’s model shows that the interplay between a Friedmanian accelerationist Phillips curve and the quantity equation is sufficient to generate business cycles in R. Frisch’s sense. According to Friedman and Schwartz much the same mechanisms potentially give rise to business cycles in the open economy with international trade in commodities and securities. They also posit that incorporating structural unemployment into the monetarist model does not affect the main results. The supply side determines average aggregate output and the interplay between supply and demand determines the fluctuations around this average level. The theoretical positions of these two schools of thought converged to a widely shared macroeconomic consensus in the early 1970s that the average output level is determined by supply-side factors, while the demand side is an important determinant of the fluctuations of aggregate production about the average level. The issue of whether monetary policy can be used to control business cycles is at the heart of the economic debate with regard to the European Monetary Union (EMU). Many believe that Gordon Brown’s view that Britain would be adversely affected economically by joining the Euro is the single largest factor as to why Britain remains a sovereign state. The argument revolves around the fact that monetary policy, if it is to have a controlling effect on an economy, is most effective when it is used to counteract localised shocks. It follows then that a single monetary policy for all EMU nations (with well-documented fundamental differences in the foundations of their respective economic status) would be less effective than implementing one specific to the UK. In conclusion, and I think most modern macroeconomists would agree, that business cycles are clearly influenced by both real and monetary shocks. As I have shown, real shocks, can offer a more identifiable force behind business cycles and yet it could simultaneously be argued that the government’s monetary policy is the more constant, driving, factor. I believe that the government should take an active role in moderating the business cycle through stabilization policies. This is because, as research has shown, short-term business cycle fluctuations may have long-term effects on the economy. The persistence of long-term unemployment in European economies is a good example of how short-term fluctuations in output and employment can create serious long-term problems for the economy. I am inclined to agree with Boehm who states ‘there are both endogenous and exogenous causes of cycles and concludes that, while each cycle is distinct, there are also common elements to all b usiness cycles.’ The implication is that any theory suggesting random elements as the main source of cycles is suspect. Since new classical theory postulates that cycles are caused by random monetary shocks and real business cycle theory places blame on technology shocks, both theories fail by Boehms criteria. Boehm concludes that an eclectic theory of the cycle is necessary and that continual monitoring is needed for stabilisation purposes. Bibliography The American Business Cycle, R. J.

Gambling and crime Essay Example | Topics and Well Written Essays - 2250 words

Gambling and crime - Essay Example The gambling industry entices people to try gambling in order to get them hooked and become addicted and the industry knows full well the consequences of an addiction. A former lawyer of John Ascuagas â€Å"Nugget† embezzled $3 million for his gambling habit and in another case, the accountant of a doctors clinic stole some $2.3 million from her employer to feed her habit of buying lottery tickets, as much $6,000 per day. She had pleaded guilty and was charged with a second-degree grand larceny. As it becomes an addiction, some decent, reasonable, respectable and rational people are really tempted to steal money and also commit other far more serious crimes like murder for their gambling addictions. Gambling involves taking the odds or probability of a certain outcome to be occurring. Gambling can take many forms such as horse racing, card games, table games, slot machines, dog racing, sports betting (boxing, basketball, soccer, etc.) and even on the Internet. Some forms of gambling are considered tame or mild in nature such as sweepstakes, lotteries and bingo games because the bet amounts are not very large although prizes can get very big. There are warning signs of a gambling addiction and people should be made aware of them. Planning a future action is a healthy attitude. This is the same principle involved when businessmen and investors go into business in order to earn money. This speculative attitude generates investments and jobs such as in the form of insurance contracts (fire, auto, marine, flood, etc.), life annuities and the modern and very complex forms of contracts like financial derivatives and stock options. The futures market in agricultural commodities is a very good example of gambling based on speculation but minimizing the risks involved. However, this paper will explore and discuss the troubling issues associated with types of gambling in the strict sense of the word. This paper looks at the problems generated by the uncontrolled urge

Project motorcycles Essay Example | Topics and Well Written Essays - 1500 words

Project motorcycles - Essay Example This structure is advantageous because there is a clear chain of command, autonomy of departments, quick decision making and sharing of skills. The following model indicates the functional structure that is intended to be applied in the developing of the larger touring class motorcycle. This implies that, a project can be completed by a specific functional group equipped with the necessary skills. The process of developing a larger class touring motorcycle involves two main stages. They include manufacturing and quality control. At the manufacturing department, the necessary materials are assembled to completion and at the quality control department; the quality control inspectors conduct a visual inspection (Cooke, Tate, & Cooke, 2011). The functional groups form reservoirs of knowledge in the areas of specialization. The groups’ efficiency is attributed to well-structured communication processes, which eases decision-making. The process of developing motors larger than 1100cc intended for long distance and a proposed global market target of males aged 35-60 years requires systematic functional units to ensure that, the company does not make losses during the changeover (Cooke, Tate, & Cooke, 2011). The following are the primary raw material essential for the development of a motorcycle. The process of manufacturing should start at the weld department. This process should be aided by the computer-controlled fabrication of frame lofty strength materials (Henshaw, 2012). The components are shaped into hollow tubular metal shells. The diverse sections are jointly welded. The process engrosses manual, automatic and computerized equipment. The plastic and metal components are painted in the booths of the paint department. The process is called powder coating. It is done by a pressurized system, which disperses the paint evenly (Henshaw, 2012). Installation of other parts such as brakes, foot pegs, seats, lights, radios, wheels and many others

The Welfare Principle in the UK Essay Example | Topics and Well Written Essays - 2250 words

The Welfare Principle in the UK - Essay Example In which, the rights, powers, duties, responsibilities and authority of the parents are provided concerning their children. In addition to that, it enables the court to hear and make decisions about the welfare of the child. The Adoption and Children Act 2002 changed the law pertaining to the parental responsibility.2 For children born on or after 1 December 2003 [England and Wales], 4 May 2006 [Scotland] and15 April 2002 [Northern Ireland], both biological parents remain owners of the parental responsibility if they are registered on the birth certificate of the child [whether or not the parents are married]. Contact Order definition According to section 8(1) of the Children Act, a contact order means an order requiring the person with whom a child lives or is to live, to allow the child to visit or stay with the person named in the order, or for that person and the child otherwise to have contact with each other.3 However, in case of clash between the interests of the parents and t he interests of children, the interests of the child will be preferred as was stated by the Court of Appeal in Re P (Contact: Supervision) [1996] 2FLR 314 at p.328. What are the interests of a child that the court is going to protect? For example, the child does not have only physical needs and educational needs, but also requires emotional support in order to grow naturally and complete the cycle of mental and physical growth. If parents are only able to satisfy the physical and education needs, but not the emotional one, it would not be easy for the court to serve and protect the interests of the child due to a clash between the different interests. Even in this case, if the court grants the contact order, the court compromises on the emotional needs of the child. On the other hand, if the court does not entertain the contact order request from the parents, the court again fails to properly serve the interests of the child. In order to ascertain the interests of the parents and th e interests of the child, the court needs to consider the contact order factors that assist whether contact order should be made or not. They include: Above all, the court has to consider what they believe to be in the best interests of child and the welfare of the child remains the main priority. In this regard, the feelings and wishes of the child as far as can be ascertained and they must be considered in the light of the child’s mental level and understanding: There is no specific age bracket provided to ascertain the mental level of a child. If the child faces a very specific mental disorder and the doctors remain unsuccessful to highlight the impact of the mental disorder on the child’s main mind function, under that situation, the age consideration may become irrelevant. Even the court decision to issue a contact order will not be able to serve the main objective of the child welfare. The court is required to take into account the child’s emotional, physi cal and educational needs as well: For example, if parents want to nurture their child and they are financially in a position to fulfil the physical and educational needs of the child, but they are unable to satisfy the emotional needs of the child. There are no particular emotional needs mentioned in the Children Act 1989 that must be satisfied before granting a contact order. In addition, there are different types of emotions and

Higher Quality Input Phrase To Driven Reverse Dictionary

Higher Quality Input Phrase To Driven Reverse Dictionary Implementing a Higher Quality Input Phrase To Driven Reverse Dictionary E.Kamalanathan  and C.Sunitha Ram ABSTRACT Implementing a higher quality input phrase to driven reverse wordbook. In contrast to a conventional forward wordbook, that map from word to their definitions, a reverse wordbook takes a user input phrase describing the specified construct, and returns a group of candidate words that satisfy the input phrase. This work has important application not just for the final public, notably those that work closely with words, however conjointly within the general field of abstract search. The current a group of algorithms and therefore the results of a group of experiments showing the retrieval accuracy and therefore the runtime latency performance is implementation. The experimental results show that, approach will offer important enhancements in performance scale while not sacrificing the standard of the result. Experiments scrutiny the standard of approach to it of presently on the market reverse dictionaries show that the approach will offer considerably higher quality over either of the opposite presently on the market implementations. Index Terms : Dictionaries, thesauruses, search process, web-based services. . INTRODUCTION A Report work on creating a reverse dictionary, As against a regular (forward) wordbook that maps words to their definitions, a WD performs the converse mapping, i.e., given a phrase describing the required conception, it provides words whose definitions match the entered definition phrase. It’s relevant to language understanding. The approach has a number of the characteristics expected from a strong language understanding system. Firstly, learning solely depends on unannoted text information, which is abundant and contain the individual bias of an observer. Secondly, the approach is predicated on all-purpose resources (Brill’s PoS Tagger, WordNet [7]), and also the performance is studied below negative (hence additional realistic) assumptions, e.g., that the tagger is trained on a regular dataset with doubtless totally different properties from the documents to be clustered. Similarly, the approach studies the potential advantages of victimization all potential senses (and hypernyms) from WordNet, in an endeavor to defer (or avoid altogether) the necessity for Word Sense Disambiguation (WSD), and also the connected pitfalls of a WSD tool which can be biased towards a particular domain or language vogue BACKGROUND WORK Natural Language Processing: Natural Language Processing (NLP) [6] is a large field which encompasses a lot of categories that are related to this thesis. Specifically NLP is the process of computationally extracting meaningful information of natural languages. In other words: the ability for a computer to interpret the expressive power of natural language. Subcategories of NLP which are relevant for this thesis are presented below. WordNet: WordNet [7], [2]is a large lexical database containing the words of the English language. It resembles the traits of a thesaurus in that it structures words that have similar meaning together. WordNet is something more, since it also specifies different connections for each of the senses of a given word. These connections place words that are semantically related close to one another in a network. WordNet also displays some quality of a dictionary, since it describes the definition of words and their corresponding part-of-speech. Synonym relation is the main connection between words, which means that words which are conceptually equivalent, and thus interchangeable in most contexts, are grouped together. These groupings are called synsets and consist of a definition and relations to other synsets. A word can be part of more than one synset, since it can bear more than one meaning. WordNet has a total of 117 000 synsets, which are linked together. Not all synsets have a distinct path to another synset. This is the case, since the data structure in WordNet is split into four different groups; nouns, verbs, adjectives and adverbs (since they follow different rules of grammar). Thus it is not possible to compare words in different groups, unless all groups are linked together with a common entity. There are some exceptions which links synsets cross part-of-speech in WordNet, but these are rare. It is not always possible to find a relation between two words within a group, since each group are made of different ba se types. The relations that connect the synsets within the different groups vary based on the type of the synsets. Application Programming Interface Several Application Programming Interfaces (API) exists for WordNet. These allow easy access to the platform and often additional functionality. As an example of this the Java WordNet Library [8] (JWNL) can be mentioned. This allows for access to the WordNet Library files. PoS Tagging PoS tags[8] are assigned to the corpus using Brill’s PoS tagger. As PoS tagging require the words to be in their original order this is done before any other modifications on the corpora. Part-of-speech (POS) tagging is the field which is concerned with analysing a text and assigning different grammatical roles to each entity. These roles are based on the definition of the particular word and the context in which it is written. Words that are in close proximity of each other often affect and assign meaning to each other. The POS taggers job is to assign grammatical roles such as nouns, verbs, adjectives, adverbs, etc. based upon these relations. The tagging of POS is important in information retrieval in general text processing. This is the case since natural languages contain a lot of ambiguity, which can make distinguishing words/terms difficult. There are two main schools when tagging POS. These are rule-based and stochastic. Examples of the two are Brill’s tagger and Stanford POS tagger, respectively. Rule-based taggers work by applying the most used POS for a given word. Predefined/lexical rules are then applied to the structure for error analysis. Errors are corrected until a satisfying threshold is reached. Stochastic taggers use a trained corpus to determine the POS of a given word. Stopword Removal Stopwords, i.e. words thought not to convey any meaning, are removed from the text. The approach taken in this work does not compile a static list of stopwords, as usually done. Instead PoS information is browbeaten and all tokens that are not nouns, verbs or adjectives are removed. Stop words are words which occur often in text and speech. They do not tell much about the content they are wrapped in, but helps humans understand and interpret the residue of the content. These terms are so generic that they do not mean anything by themselves. In the context of text processing they are basically just empty words, which only takes up space, increases computational time and affects the similarity measure in a way which is not relevant. This can result in false positives. Table: 1 List of Stop words This class includes only one method; which runs through a list of words and removes all occurrences of words specified in a file. A text file, which specifies the stop words, is loaded into the program. This file is called â€Å"stop-words.txt† and is located at the home directory of the program. The text file can be edited such that it only contains the desired stop words. A representation of the stop words used in the text file can be found in table 1. After the list of stop words has been loaded, it is compared to the words in the given list. If a match is found the given word in the list is removed. A list, exposed from stop words, is then returned. Stemming Words with the same meaning appear in various morphological forms. To capture their similarity they are normalised into a common root-form, the stem. The morphology function provided with WordNet is used for stemming, because it only yields stems that are contained in the WordNet dictionary. This class contains five methods; one for converting a list of words into a string, two for stemming a list of words and two for handling the access to WordNet through the JWNL API[8]. The first method listToString() takes an ArrayList of strings and concatenate these into a string representation. The second method stringStemmer() takes an ArrayList of strings and iterates through each word, stemming these by calling the private method wordStemmer(). This method checks if the JWNL API has been loaded and starts stemming by looking up the lemma of a word in WordNet. Before this is done, each word starting with an uppercase letter is checked to see if it can be used as a noun. If the word can be used as a noun, it does not qualify for stemming and is returned in its original form. The lemma lookup is done by using a morphological processor, which is provided by WordNet. This morphs the word into its lemma, after which the word is checked for a match in the database of WordNet. This is done by running through all the specified POS databases defined in WordNet. If a match is found, the lemma of the word is returned, otherwise the original word is simply returned. Lastly, the methods allowing access to WordNet initializes the JWNL API and shuts it down, respectively. The initializer() method gets an instance of the dictionary files and loads the morphological processor. If this method is not called, the program is not able to access the WordNet files. The method close() closes the dictionary files and shuts down the JWNL API. This method is not used in the program, since it would not make sense to uninstall the dictionary once it has been installed. It would only increase the total execution time. It has been implemented for good measure, should it be needed. Stemming[5] is the process of reducing an inflected or derived word to its base form. In other words all morphological deviations of a word are reduced to the same form, which makes comparison easier. The stemmed word is not necessarily returned to its morphological root, but a mutual stem. The morphological deviations of a word have different suffixes, but in essence describe the same. These different variants can therefore be merged into a distinct representative form. Thus a comparison of stemmed words turns up a higher relation for equivalent words. In addition storing becomes more effective. Words like observes, observed, observation, observationally should all be reduced to a mutual stem such as observe. PROPOSED SYSTEM Reverse dictionaries approach can provide significantly higher quality. The proposed a set of methods for building and querying a reverse dictionary. Reverse dictionary system is based on the notion that a phrase that conceptually describes a word should resemble the word’s actual definition, if not matching the exact words, then at least conceptually similar. Consider, for example, the following concept phrase: â€Å"talks a lot, but without much substance.† Based on such a phrase, a reverse dictionary should return words such as â€Å"gabby,† â€Å"chatty,† and â€Å"garrulous.† Forward mapping (standard dictionary): Intuitively, a forward mapping designates all the senses for a particular word phrase. This is expressed in terms of a forward map set (FMS). The FMS of a (word) phrase W, designated by F(W) is the set of (sense) phrases {S1, S2, . . . Sn } such that for each Sj à Ã¢â‚¬Å¾ F(Wi), (Wi à ¯Ã†â€™Ã‚   Sj) à Ã¢â‚¬Å¾ D. For example, suppose that the term â€Å"jovial† is associated with various meanings, including â€Å"showing high-spirited merriment† and â€Å"pertaining† to the god Jove, or Jupiter.† Here, F (jovial) would contain both of these phrases. Reverse mapping (reverse dictionary): Reverse mapping applies to terms and is expressed as a reverse map set (RMS). The RMS of t, denoted R(t), is a set of phrases { P1, P2, Pi,†¦Ã¢â‚¬ ¦, Pm}, such that à ¯Ã¢â€š ¬Ã‚ ¢Pi à ¯Ã¢â€š ¬Ã‚  Ãƒ ¯Ã†â€™Ã… ½ R(t), t à ¯Ã†â€™Ã… ½ F(Pi). Intuitively, the reverse map set of a term t consists of all the (word) phrases in whose definition t appears. The find candidate words phase consists of two key sub steps: 1) Build the RMS. 2) Query the RMS. A. COMPONENTS The first preprocessing step is to PoS tag the corpus. The PoS tagger relies on the text structure and morphological differences to determine the appropriate part-of-speech. For this reason, if it is required, PoS tagging is the first step to be carried out. After this, stopword removal is performed, followed by stemming. This order is chosen to reduce the amount of words to be stemmed. The stemmed words are then looked up in WordNet and their corresponding synonyms and hypernyms are added to the bag-of-words. Once the document vectors are completed in this way, the frequency of each word across the corpus can be counted and every word occurring less often than the pre specified threshold is pruned. Stemming, stopword removal and pruning all aim to improve clustering quality by removing noise, i.e. meaningless data. They all lead to a reduction in the number of dimensions in the term-space. Weighting is concerned with the estimation of the importance of individual terms. All of these have been used extensively and are considered the baseline for comparison in this work. However, the two techniques under investigation both add data to the representation. a PoS tagging adds syntactic information and WordNet is used to add synonyms and hypernyms. B. BUILDING REVERSE MAPPING SETS The input phrases sentence is split into words and then removes the stop words ( a, be, person, some, someone, too, very, who, the, in, of, and, to) if any appears, and find other words, which is having same meaning from the forward dictionary data sources. Given the large size of dictionaries, creating such mappings on the fly is infeasible. Thus, Procreate these Rs for every relevant term in the dictionary. This is a one time, offline event; once these mappings exist, we can use them for ongoing lookup. Thus, the cost of creating the corpus has no effect on runtime performance. For an input dictionary D, we create R mappings for all terms appearing in the sense phrases (definitions) in D. C. RMS QUERY This module responds to user input phrases. Upon receiving such an input phrase, we query the R indexes already present in the database to find candidate words whose definitions have any similarity to the input phrase. Upon receiving an input phrase U, we process U using a stepwise refinement approach. We start off by extracting the core terms from U, and searching for the candidate words (Ws) whose definitions contain these core terms exactly. (Note that we tune these terms slightly to increase the probability of generating Ws) If this first step does not generate a sufficient number of output Ws, defined by a tuneable input parameter ÃŽ ±, which represents the minimum number of word phrases needed to halt processing and return output. D. CANDIDATE WORD RANKING In this module sorts a set of output Ws in order of decreasing similarity to U, based on the semantic similarity. To build such a ranking, we need to be able to assign a similarity measure for each (S,U) pair, where U is the user input phrase and S is a definition for some W in the candidate word set O. Wn and Palmer’s Conceptual similarity, WUP Similarity between concepts a and b in a hierarchy, Here depth(lso(a,b)) is the global depth of the lowest super ordinate of a and b and len(a,b) is the length of the path between the nodes a and b in the hierarchy SOLUTION ARCHITECTURE We now describe our implementation architecture, with particular attention to design for scalability. The Reverse Dictionary Application (RDA) is a software module that takes a user phrase (U) as input, and returns a set of conceptually related words as output. Figure 1. Architecture of reverse dictionary. The user input phrase, split the word from the input phrase, perform the stemming. Predict every relevant term in the forward dictionary data source. In the generate query. input phrase, minimum and maximum output thresholds as input, then removal of level 1 stop words ( a, be, person, some, someone, too, very, who, the, in, of, and, to) and perform stemming, generate the query.Execute the query find the set of candidate words. Finally sort the result based on the semantic similarity EXPERIMENTAL ENVIRONMENT Our experimental environment consisted of two 2.2 GHz dual-core CPU, 2 GB RAM servers running Windows XP pro and above. On one server, we installed our implementation our algorithms (written in Java). The other server housed is wordnet dictionary data. CONCLUSION We describe the many challenges inherent in building a reverse lexicon, and map drawback to the well-known abstract similarity problem. We tend to propose a collection of strategies for building and querying a reverse lexicon, and describe a collection of experiments that show the standard of our results, similarly because the runtime performance underneath load. Our experimental results show that our approach will give important enhancements in performance scale while not sacrificing answer quality. The higher quality input phrase to driven reverse dictionary. Unlike a traditional forward dictionary, which maps from words to their definitions, a reverse dictionary takes a user input phrase describing the desired concept, it reduce the well-known conceptual similarity problem. The set of methods building a reverse mapping querying a reverse dictionary and it produces the higher quality of results. This approach can provide significant improvements in performance scale without sacrificing solution quality but for larger query it is fairly slow. REFERENCES T. Dao and T.

The Politics of Name Changes in India Essay -- Town City

The Politics of Name Changes in India Ever since independence in 1947, many locations in India have changed their names. Much of this resulted from the reorganization of the states on linguistic lines (as opposed to British colonial divisions). However, in the last six years, many major towns and cities have been renamed in ways that affect foreigners more. Among this flood of changes, three stand out. These are the former cities of Bombay, Madras, and Calcutta, which, together with Delhi, are considered the "mega cities" of India.1 They are the four most populous cities in India, and all but Madras are among the 15 most populous cities in the world.2 As a result, they are important commercial and transit hubs, and are well known outside India. Yet nearly six years later, most non-Indians still have no idea that they are now named Mumbai, Chennai, and Kolkata. Given the difficulties involved in these changes, one expects compelling justifications for the changes. In each case, these changes have officially been justified on anti-colonialist grounds. However, I will argue that these changes are instead tools for channeling regionalist sentiment in the conflict between the Hindu nationalist Bharatiya Janata Party (BJP), the centrist Indian National Congress (INC), and various regional parties. Opponents of the INC proposed all these names, but those proposed by the BJP and its nationalist allies have been more divisive. The case of Mumbai was the first major change to happen, and is thus the best known. In 1995, the ruling party in the government of the state of Maharashtra (of which Bombay was capital) announced that Bombay's name would be changed to its Marathi name, Mumbai.3 The casual observer would assume that the name "B... ...ttp://www.hartford-hwp.com/archives/52a/076.html - a BBC article about the Kolkata name change * http://www.lonelyplanet.com/destinations/indian_subcontinent/mumbai/history.htm - a travel site with a history of Mumbai.

Assess the View on Whether or Not Roles in Relationships

H/W Assess the view that roles and relations among couples are becoming more equal (24 Marks) Numerous sociologists have suggested that a large number of relationships are now becoming more symmetrical in compare to the traditional families looking back 40, 100, 200 years ago. They say that the traditional male and female roles are no longer as they were before, it has all fallen apart, and hence relationships have been becoming more equal. Some sociologists such as Wilmot and Young argue that in symmetrical families, normal domestic duties are most likely to be shared by both parties and they are both very likely to be working.Thus it all undoes the tradition of the past in which a woman would care for the children and the home, and the man being the ‘breadwinner’ would head out and work. Some sociologists also argue that the decision making is no longer only within the man’s hand as it once was, but also in the woman’s hands, the symmetrical family has an equal partnership in decision making. All this evidence leads some sociologists to view the roles and relations of couples to have been becoming somewhat more equal in compare to the past.On the other hand, some sociologists such as Morgan(1996) argue that women now take part in an act known as the ‘Triple Shift’, this is when women go out and work, but then also do domestic work when at home and give emotional support to partner and children. As a result, many feminists would argue that the roles and relations of couples are not equal, but actually unfair, the woman is doing so much more than her partner. This views result in some sociologist believing that roles and relations have changed in compare to the past, but in a path towards the woman doing more work than the man, making her the ‘breadwinner’.In conclusion, many sociologists believe that the roles and relations of couples have been becoming more equal, but there are some who still view it to not being equal at all, and some even arguing that women are doing more work than the men. From this evidence it is clear to say that it is not clear whether or not roles and relations are becoming more ‘equal’, but many sociologists argue that there has been a big change in compare to the past traditions, but whether or not it’s towards the path of the ‘more equal’ is still being argued by many.

Mate Selection Theories essays

Mate Selection Theories essays To describe men and women's differential preferences in mate selection, I am going to use the following theories: 1) sexual selection theory, 2) parental investment theory, and 3) social learning theory, and 4) sexual strategies theory. All of these theories have been used to explain why men and women have differential preferences in mate selections. In the evolutionary approach, biological fitness is defined as reproductive success. Therefore, understanding particular behavioral sex differences is of great interest to evolutionists. Reproduction is central to the evolutionary process and no domain is closer to reproduction than sexuality. Darwin (58) adopted phrase "survival of the fittest" to summarize the process of natural selection, but this choice was unfortunate. Survival is certainly critical. Many adaptations of organisms exist because they successfully overcame the forces that impeded survival, such examples are parasites, diseases, food shortages, predators, and Darwin (67) also fashioned the use of term what he believed to be a second evolutionary process, which he called sexual selection. According to sexual selection theory, characteristics that give organisms an advantage in the competition for mates can also evolve. Sexual selection can operate through two processes. The first is intrasexual or same-sex competition. If members of one sex compete with one another, and the victors of these competitions gain preferential sexual access to mates, then these useful qualities lead to success in same-sex competitions will be selected and can evolve over time. These might include athletic ability, social skills to enlist allies, or even a sense of humor that deters a rival. The key point is that whatever qualities lead to success in same-sex competitions can evolve because of the reproductive advantage that accrues to the victor The second component...

Dictatorship essays

Dictatorship essays In modern times, no dictator can take total power by force alone. In order to gain support, they must offer something beneficial to the people. Unfortunately what is thought to be beneficial can be extremely harmful and cruel. Three specific dictators during the World War II period were Mussolini, Hitler, and Stalin. Joseph Stalin was the successor of Lenin after his death. He had only one goal and that was to finish what Lenin had started. Basically that was to build a classless society in which the means of production were in the hands of the people. After Stalin established power, he developed new goals to make the Soviet Union a leader in industry. He wanted to get rid of Russias backwardness. For this reason Stalin proposed several five year plans. These plans were aimed at improving industry and economic growth. He developed a command economy, which meant government made all economic decisions. Under Stalin, the government controlled all businesses. Stalin also took agriculture under control of the government. He forced people to give up their privately owned land and live on government-owned farms or on large farms that were owned and operated by groups, also known as collectives. The state set all prices and controlled access to farm supplies. (Comptons Encyclopedia, 1990, Joseph Sta lin S570) On July 29, 1921, Adolf Hitler was introduced as Fuehrer of the Nazi Party. Fuehrer basically meant leader. By November 1923, the Nazis held approximately 55,000 followers and were the biggest and most powerful in Germany. The Nazi Party demanded action of Hitler. Hitler knew that he would lose his support if he didnt do something fast. So he and his party developed a plan to kidnap the leaders of the Bavarian government and force to accept Hitler as their leader. On November 9th, 1923 Hitler and his Nazis went to Munich and tried to take it over. At this point they were not powerful enough to ...

Near Shoring Assignment Example | Topics and Well Written Essays - 250 words

Near Shoring - Assignment Example This is because near shoring allow businesses to operate near the home country (Shamis, Green, Sorensen t al, 2005). Near shoring allows businesses to conduct their activities in regions with the same time zones. This implies that through this business strategy, it is easier for a business to control all its operations immediately. It also makes the communication process easier. This enables them to coordinate their operations easily and faster. It is difficult for organizations to conducts the same projects in different time zones. In order to achieve the goal of the company, workers in a region with a different time zone have to sacrifice by working at night. Working late in the night may reduce the productivity of workers (McGrath, 2014). Companies that practice near shoring also experience less legal issues compared to those that engage in outsourcing. Outsourcing makes a company to incur huge immigration costs and other costs associated with government regulations. However, in near shoring companies have to only deal with neighboring countries which have less immigration and legal issues. Near shoring also enables a company to enjoy geographical proximity benefits. For instance, it is easier for a company to interact with its customers if they can easily be reached. The situation helps in increasing their

Kinship among South Indian Communities Literature review

Kinship among South Indian Communities - Literature review Example Kinship among South Indian communities has been indispensable and the main form of social organization (caste system). The caste system was a closed hereditary group to which a person belonged strictly by birth. At one point, there were relationships based on endogamous marriage between two people from the same caste. Kinship is also concerned about the productive anxiety of relations of distinction and sameness, the main aspects being the ties that separate or bind. In a fishing village, ‘the Marianad’ what matters is the relations between siblings. The children of the same father and mother, siblings are similar apart from their gender. The strongest differentiation is made between siblings of different gender, a difference that has a great effect in the following generation (Busby 2000; 1995). Therefore, among the â€Å"Marianads† sisters are viewed to be identical in a manner that brother and sister cannot be. Sisters in this tribe, live closely, they are spot ted with each other baby either carrying or feeding it. Contrary, brothers are different in that they move to their wife’s houses in distinct villages, although they view their brother’s children as their own, and they often refer to them as their daughters or sons. The word Dravidian refers to a family dialect mainly spoken in South India. The Dravidian family is different in both origin and structure from the Anglo-Aryan family located in North India. People from South India classify kin based on the difference in sex, the difference in age, the difference in generation, and difference of kin identical with union relationship. This system exemplifies a sociological theory of marriage, and it justifies the issue of someone marrying a cross-cousin (Clark-Deces 2011; Bourdieu 1997). The Marianad people do not have the separate terminologies for the younger and elder sibling, uncles, and aunts. They also do not differentiate between kin identified to ego’s parents via same-sex association (parallel kin) and kin identified to ego’s parents via opposite se-associations. Writers such as Dumont try to suggest the differentiation between the cross and parallel kin in comprehending marriage choices and decisions in South India (Dumont 2006). The children of parents’ same or similar sex siblings (the fathers-in-law and mothers-in-law) are absorbed to the position of elder or young siblings, with whom sexual intimacy, marriage and sexual activities are prohibited. On the other hand, the children of parents’ cross-sex siblings (fathers-in-law and mothers-in-law) are absorbed to the position of spouses or wives with whom marriage is accepted or permitted in that in some castes in south India, it is preferred and prescribed. It is significant to note that these terms recommend separation between relatives (in-laws) and kin, which is not the same as our cultural differentiation between relatives by marriage and blood relatives.
