The Demarcation Issue free essay sample

The boundary between science and pseudo science, better known as the demarcation issue has been in debate for decades between philosophers of science in order to find the basis on which this separation can exist. The likes of Karl Popper initially introduced the demarcation criterion called falsificationism which states that falsifiability is the logical possibility that an assertion can be shown false by an observation or a physical experiment[l] and it was on this beginning that Popper was able to make the distinctive separation of science from pseudoscience. However f Poppers approach was taken into consideration, many scientific discoveries would have been impoverished, since the theory behind the discovery would have been deemed a pseudoscience due to the lack of proof and experimentation supporting it. Paul Thagard, Imre Lakatos and Thomas Kuhn are some of the strongest opponents of the model of falsificationism. Poppers demarcation has been critisized for its disregard for legitimate science and for allowing pseudoscience the eminence of a science. We will write a custom essay sample on The Demarcation Issue or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This essay contrasts the ideologies of Karl Popper with the 3 philosophers ith regards to certain scientific discoveries which consequently reveal the inadequacy of falsificationism as a demarcation criterion. Karl Popper described the demarcation problem as the key to most of the fundamental problems in the philosophy of science. [2]The scientific revelation that contradicts Poppers proposal is Isaac newtons concept of gravity. Gravity through newtons explanation is an invisible, mass less, attractive force between objects that have mass. [3] It is what keeps humans on earth and the earths orbiting of the sun. With regards to Popper he theory of gravity is in fact a pseudoscience since it is simply a question of how can one undergo a physical experiment or observation in which newtons theory of gravitation can be refuted? The lack of proof to support this theory is the principle of Poppers disregard to gravitation as a scientific discovery. On the contrary, Paul Thagard disapproval of Poppers ideology is prominently seen here, as Popper so hastily disregards the theory of gravitation. Thagards approach states that a scientific theory is deemed a pseudoscience if it has been less progressive than lternate theories over a long period of time and thus solves many unsolved problems. [4] His thesis does not neglect experiments altogether. Accordingly a theory us only considered a pseudoscience if it is left to stagnate thus portraying minimal progression in comparison to alternatively proposed theories. When this is compared to Poppers idea of separation between science and pseudoscience, regardless if a theory is falsifiable Thagard implies that if progress is not made and it is left to degenerate it only then is namely a pseudoscience. Therefore we should ake newtons law of gravitation into consideration. Although there is little confirmation that gravity at all exists, the mere fact that it has made significant scientific progression and hence was later used as a foundation of other scientific manifestations. With reference to Thagards proposal, newtons law of gravitation is appraised a science. Evidently Poppers falsificationism criterion would have in fact delayed crucial scientific progression due to its strict paradigm as opposed to Thagards neglect of the intrinsic features of a theory. And hence promotes a more alsificationism as demarcation criterion. The history of science from Kuhns view paints a picture very different from that of positivists like Karl Popper, he criticises Poppers idea and states that his falsifiability criteria fails to characterise science as it is actually practice. Kuhns proposed thesis suggests that true scientific practice consists of puzzle solving with the current accepted theory, by contrast pseudoscience do not provide this framework for progressive research. There are more difference between Popper and Kuhns ideologies on the methods of alsificationism, where Popper argues that the hallmark of science is its decisive approach and thus always trying to falsify itself. Kuhn on the other hand asserts quite the opposite it is when everybody agrees on the basic theories that the scientific discovery will rise from the ground. For instance, Kuhn and Popper are critical of whether or not astrology is a science. From Poppers perspective it cannot be, since the claims astrologers present are very vague and nothing can be refuted. Kuhn on the other hand suggests that astrologers have actually acknowledged many ailed predictions and that these failures were much explained. The exact configuration of constantly moving stars and planets as well as the exact time of a persons birth is too difficult to calculate perfectly. [5] If this was viewed in a much simpler analogy, the factors that contribute to lung cancer are too complex to determine, that we cant actually predict with uttermost certainty that smoker will definitely get cancer, however it is still correct to say that smoking causes cancer and that medical studies of smoking and lung cancer are scientific. For that reason is its lear that Poppers demarcation of science and pseudoscience is not effective. Imre Lakatos attempted to explain Kuhns work in falsificationists terms by arguing that science progresses by the falsification of research programs rather than specific universal statements of naive falsification. In Lakatoss approach a scientists works in a research program which corresponds to Kuhns paradigm. Whereas Popper rejected the use of ad hoc hypothesis as scientific, Lakatos acknowledged their position in the development of new theories. Furthermore the discovery made by Thompson that all matter presents both wave and particle like features[6] is another scientific discovery that has created conflict between the views of Popper and Imre Lakatos. Light was always believed to delineate wave like characteristics, however when Thompson first revealed that in fact matter could exhibit both types of properties the original theory was considered a pseudoscience. The stringent standard of falsification does not allow for any error to occur within theories. In fact falsificationism does not question the reliability and validity of the experimental ethods and whether or not they were carried out correctly, but rather objects to the theory itself. Additonally if we were to examine Lakatoss proposal on the demarcation issue, he states that scientists do not give on a theory because some counter evidence is found. Instead either the evidence is put into question or the same ad hoc hypothesis is appealed to for rescue. [4] From Lakatos thesis of separation, Thompsons claim is considered a science for the reason that he not only made an ad hoc hypothesis but rather was able to further prove that light also xhibited particle features. All through his paddle wheel and Maltese cross experiments and wave like features thoroughly through the use of a magnetic field. proven false based on observation and experimentation indicates its inadequacy as a demarcation criterion as it does not adhere to the wave particle scientific theory. Poppers ideologies suggest that a theory is a pseudoscience if it cannot be refuted. The demarcation that separates the two sciences is built on a very distinctive basis for the remaining philosophers. Analysis of Newtonians ideas suggest that the latter iscoveries would have been delayed since there were many attempts to falsify Netwons theories. Which in turn would have belated the findings of Neptune and prevented the progression of the kinetic theory of gases. Consequently the establishment of the quantum theory would also have ceased to exist since the understanding of mechanics would have been disregarded had Poppers idea of falsificationism and demarcation were taken into account. All these scientific revelations have led to great inventions and further scientific advancements. The quantum theories through mathematical laws were in fact able to provide scientists he reasons for the way in which a black body radiates heat[6]. According to Popper the only way that science can advance is when one conjectures then another refutes. If there is no refute or it is considered insufficient then it is not taken into consideration as scientific progression. If this approach was to be followed a great deal of knowledge would be lost as Popper doesnt allow time for a theory to prove its accuracy. It is there evident that falsificationism is not adequate as a demarcation criterion. Scientists will go to great lengths to defend their paradigm against alsification, by the addition of ad hoc hypothesis to existing theories. Paul Thagard, Thomas Kuhn and Imre Lakatos are the strongest adversaries of the theory of falsificationism which provides the indication that there is still much philosophical work to be done on the demarcation between science and pseudoscience. Falsificationism is inadequate as a demarcation criterion as it hastily disregards theories presented without giving them the time to prove their validity. Also it has been criticised for disregarding Justifiable science and for giving pseudoscience the status of being science.

Criminal Tendencies essays

Criminal Tendencies essays Say the word marijuana and people immediately associate it with something: crime, druggies, lack of motivation, or other negative connotations. For far too long in American culture millions have believed propaganda about marijuana, spread by the government, without ever educating themselves. Marijuana, which comes from the cannabis plant, is not nearly as harmful as it has been made out to be. Opponents scream that smoking pot kills brain cells and gives cancer to users. Alcohol kills brain cells, is an addictive drug, and is legal. Tobacco gives cancer to users, is an addictive drug, and is legal. Pot smokers are often stereotyped as being unmotivated, burned out failures, despite many avid users from all avenues of life. Success depends on the individual, not the hobby in which they indulge. Furthermore, many events, including movies, music, and even sex can be enhanced through the euphoric feeling attained by smoking cannabis. Essentially, smoking marijuana is a victimles s crime that enhances everyday activities without hindering personal successes. Marijuana, when inhaled, gives the user a euphoric feeling which includes an altered perception of time and distance, intensified sensory experiences, and increased laughter. Ironically, euphoric is defined as a greater state of happiness and stems from the Latin word euphoros, meaning healthy. It was legal in this country until 1937, when the government passed the Marijuana Tax Act, which required tax stamps to obtain marijuana that were never supplied. The government feared that cannabis would compete with newly invented synthetic fiber, and thus they began spreading negative propaganda about marijuana. Because of this propaganda, peopl associate marijuana with harsher illegal drugs such as cocaine and heroin. However, it is important to separate marijuana from this group. Marijuana is naturally grown, harvested, dried, and smoked, much like tobacco. Cocaine and ...

Poverty in Afica ( Ghana) Research Paper Example | Topics and Well Written Essays - 2000 words

Poverty in Afica ( Ghana) - Research Paper Example For this reason Africa has poised to become the next frontier of economic growth, yet Ghana and many other African nations have continued to remain in poverty. Majority of the citizens are still in the poverty and a significant proportion has continued to enjoy chronic extreme poverty. In Ghana 28% of the population is living conditions of extreme poverty (Owusu and Mensah, 2013). In this paper therefore, I will be exploring some of the reasons behind Ghana state of poverty despite possessing vast natural resources. Ghana continues to remain poor yet the country is home to vast mineral deposits, arable agricultural land and many other natural resources that are vital to economic development. At a time when manufacturing industries in the Europe, china, Japan, America and beyond are sourcing raw materials almost entirely from the African continent, Ghana and many other nations in Africa have no viable industrial or manufacturing economy beyond agro processing and production of raw materials. This situation can be looked at from different perspectives. Firstly, some have argued that Ghana and the entire Africa lacks knowledge on what can be done with the vast wealth in terms of oil, minerals and gas deposits. It can as well be argued that Ghana does not place any economic value at all to the rich mineral resources. Yet it can also be argued that that Africans are traditionally non-capital oriented and as such they derive satisfaction from just the surface value rather than what lies beneath their natural resource wealth. The most important issue here is that Africa and Ghana in particular is a net exporter of raw materials and this translates into transforming economic benefit for its citizens as would be if it were converting these raw materials into finished products for export. The biggest problem facing Ghana with its rich natural resource base revolves around the capability of converting the resources on a mass scale into finished

Communication eassy 7 - Essay Example Earliest films were very short, often just a minute or ten, one or two reels and eventually it goes up to 2 hours. (The Birth and Early Development of   the  Motion Picture,by Robert P. Brooks, Bulletin of the Passaic County Historical Society, April 1959). We can see a gradual development in the field of motion picture. Several inventors set up their projector machine in make shift halls and projected moving pictures on a screen. The ides of longer film with story began in 1895. The man named James .H White produced a picture 500 feet in length. It was called ‘American Fireman’. Today motion pictures have predisposed both in maintaining social order and powerful agents of change. Films are cultural artifacts formed by special cultures. Motion pictures have been a great influence in the cultural field. It affected the society too much. When motion pictures transformed from black-and –white to colour in U.S in the 1950’s the sensors struggled much to eli minate erotic imagery, and immoral treatment of sexuality. Many directors of that time violated the moral side of film industry. A good example for such film is â€Å"Lady Chatterleys Lover†, banned by New York censorship board in 1957. (Vaughn). Nudity, explicit sexual behavior, profane language, gratuitous violence, and themes of promiscuity, homosexuality, abortion, drug use, etc were the chief characteristics of the films of that time. The year 1968 marked tremendous changes in U.S. film industry. A new system of Production Code has been adopted that prevented the government censorship. Censors edited the films before they reached the theatres. A kind of spiritual and moral progress was visible in the films of 1930’s and it also promoted high social life and enlightened thinking. Those Films which were not acceptable to the social morality were severely opposed by the Roman Catholic Church and they were banned in the

Communication - Essay Example It is therefore important to effectively correspond to all stakeholders on appropriate strategies and objectives for calamity control procedures. This paper describes the five critical assumptions of an effective disaster communication strategy. To understand the five critical assumptions of an effective disaster communication strategy, it is important to posit that these strategies are based on the divergent stages of an effective calamity management procedure. Disaster management is categorized into various stages i.e. mitigation, preparedness, responses, and recovery stages. Consequently, a useful calamity communication plan of action has five basic postulations. According to Haddow, Bullock and Coppola, these include â€Å"customer focus, leadership commitment, inclusion of communication in planning and operations, good information, and media partnership† (134). Customer focus Studies done in the past have elucidated the fact that an effective disaster control structure is ought to focus on the consumer. In other words, the first priority should be to benefit the consumer. According to Haddow, Bullock and Coppola, an efficient disaster control structure considers the requirements and desires of the consumer and necessitates all stakeholders to be alert, quick to respond, and instructive. It is of significance to consider the fact that the consumers of a disaster control procedure are varied and may comprise workers or employees from international organizations, national institutions, governments, as well as a number of additional stakeholders associated with calamity control. It may also comprise o local individuals. Available sources posit that information relayed to each of the consumers affected must be on the basis of individual or institutional requirements (135). Leadership commitment According to Haddow, Bullock and Coppola, the initial stages a successful disaster control plan of action is established or instituted in participation and involv ement of the individuals involved in decision making within the body or institution involved in the process. Decision makers in the body conducting the operation must be loyal in terms of giving out and publicizing facts associated with the impending calamity. It is also important to involve decision makers in other related bodies and stakeholders as well as the local leaders in propagating all the facts of the calamity. This is attributed to the fact that articulate discharge of the relevant and useful facts regarding an impending calamity is important and hence individuals with necessary communication skills such as local leaders of the involved body are ought to be involved (135). Decision makers in a calamity situation are also ought to candidly encourage, approve, and support effective sharing and exchange of facts and information among all the stakeholders. Preparation and implementation It is also of importance to posit that dedication and loyalty of decision makers in disast er correspondence in relation to forecasting, preparation, and necessary procedures is critical. An expert in correspondence matters should therefore be involved and be incorporated or integrated in the decision-making group. Discharge of relevant information and facts of an impending calamity as well as other plans of actions geared towards mitigations procedures has been made less complicated by the use

Copper Recovery Methods From Metallurgical Waste

Copper Recovery Methods From Metallurgical Waste REVIEW OF COPPER RECOVERY METHODS FROM METALLURGICAL WASTE Apurva Patel, Prof. Nimish Shah Abstract: Copper is one of the most used metals in recent developments and demand of this red metal is increasing with passing of each day. Production of copper is 12 million tons per year and copper reserves are expected to run for 25 years with the estimated world copper reserves of 300 million tons. Recovery of copper from metallurgical waste is a trend that is being followed from beginning of industrial age and has many developments over a large time frame. Out of all the copper used in existing process, 2 million tons of copper is utilized with recycling of copper waste. Copper ore reserve contribution of India is limited and extended up to 2 percent of world reserve. We can say that copper has a large amount at our reserves but excavation is not as simple as it seems. Copper content in the raw mines is ranging from 0.5 to 1 percent. Even after recovery of copper there is large waste generated at the end of the process. Copper content in the waste is up to 0.3 percent at the dis charge. Ultimately around hundred times of waste is generated for recovery of one part of copper. That pushes forward the need of recycling copper from metallurgical waste to cater the need of increasing copper demand. Copper recovery from high copper containing metallurgical wastes like brass industries are generally dealt with smelting process. In such case large amount of energy is utilized to just melt down all the material. This process has a limitation of copper content i.e. if copper content is low then all the energy is utilized in melting of undesired material. Demand for electroplating of copper has increased significantly. Low efficiency or improper process handling causes remarkably high copper content in waste discharge, which is over the range of discharge criteria of heavy metals. So to control the increasing price of metals and to limit the use of fresh copper, recycling must be done so the recovery from waste also gives the advantage of being in range of the allowab le government legislations. Though these hazardous heavy metals in electroplating waste having concentration high enough to give harmful impacts to environment but convincingly low concentration that is not enough to recover these metals effectively. In this paper, overview of different methods for copper recovery is illustrated and justified the selection of different methods over different copper content of various sources. Keywords— Copper extraction, Copper recovery, Electroplating, Recycling, I. INTRODUCTION Increasing demand of copper gives elevated chances for generating copper waste from different industries. There are thousands number of industries existing which includes utilization or processing of copper. In this paper, review of several most copper containing waste and most optimum copper recovery methods are described. Waste source is targeted which gives better possibilities of copper recovery and ease of operation. Several metallurgical source like; brass slag, copper converter slag, electroplating waste, bonze scrap and pickling solution is included in the study. II. Copper recovery from Copper slag There are different verities of slag produced from smelters for non-ferrous production. Major emphasis is given to copper slag as it has equal to or higher copper content compared to raw copper ore. Generation and utilization of copper slag has higher environment impacts compared to steel and iron slag as they contain remarkable quantity of heavy metals with higher solubility. Chemical composition of copper slag varies with different origins. Chemical composition is given as per Shen Forssberg, 2003[1] in table 1. TABLE I Chemical composition of copper slag There are specific three methods to recover copper from copper slag; Floatation, Leaching and Roasting Floatation Barnes (1993) [2] has given industrial floatation process at Mount Isa Mines Limited to recover copper from copper slag. Grinding operation is applied until obtain the granular size of 80%- 74  µm before floatation. Floatation is also feasible for magnetite present in the raw copper slag, so hydroxy ethyl cellulose is used in the process as a depressant of magnetite impurities. MIBC is used in the process as froather agent and sodium sec-butyl xanthate is used as a collector of copper from the waste. The result of this process gives concentrate grade copper with high percentage as 42.54%. Overall yield of such process is 82%. This experiment is observed for copper slag containing 3.7% copper. In this experiment most of Co is observed with floatation tail. Mainly, copper slag floatation is somewhat similar with sulfide ore floatation because of the fact that only metallic copper and sulfide minerals from the copper slag can only be effectively floated. In other slag copper is usually observed under oxide state and Co and Ni are also in oxide state because of its homogeneous distribution in the slag. So the stated method will not be utilized effectively with Co, Ni and oxide copper state. Therefore the span for the floatation process is reduced in size as less quantity of Co, Ni must be present in the slag or copper must not be in the form of oxide. Leaching Leaching is used with some leachants mainly hydrochloric acid, ferric chloride, ammonia, sulphuric acid etc. Basire at al anand at all [3]. In the initial era cyanide was also used but it was terminated because of its harmful effects to environment. Leaching is positively influenced by addition of H2O2, or leaching with Cl2/Cl system, or pressure leaching. Figure 1 shows effect of H2O2 on leaching of copper based on the experiments of Base metal recovery [4] Figure 1. Kinetics of copper recovery Graph showing metal recovery with highly oxidising agent like H2SO4 for copper slag. Experiment is carried out with 10% solid in solution and particle size less than 100  µm. Experiment is carried out at 70 oC and pH maintained at 2.5 with applied H2O2 at 35 L/(h.t) Pressure leaching has broadly described by anand et al [4]. Study shows that with pressure leaching and use of dilute H2SO4 recovery of copper about 90% achieved from copper converter slag from the initial concentration of 4.03% Cu. Roasting Roasting is actually one intermediate step which involves the process for converting the copper in desired form that can be easily separated from the raw material. After application of roasting, Leaching or floatation must be used to achieve desired separation. If we narrow down the process criteria then we can say a lot more specific term as sulfate roasting instead of roasting. In this process conversion of cupper cobalt ant nickel is taking place and transformed into more feasible soluble sulfates. Raw material is processed at 200-600 oC by addition of sulfide or sulfate agents. Then these soluble sulfates are dissolved in water and easily separated from slag. Some of the agents used in the process are, (NH3)SO4, H2SO4, H2S, pyrite etc. Sulfurization reactions are summarized as bellow. Cu2O + H2S = Cu2S + H2O †¦(1) 2Cu + H2S +  ½ O2 = Cu2S + H2O †¦(2) Sulfides of copper are then easily converted to soluble copper sulfate with roasting at 600oC. Ziyadanogullari used this method to treat copper slag containing 2.4% copper. By sulfurization in closed system with 140oC for 1 hour and then heating and roasting with 600oC for 360 minutes gives better result for recovery of copper up to 99.2%. SCHEMCON-20141 | Page

Alcoholism and Drinking - Alcohol and Personality :: Exploratory Essays Research Papers

Alcohol and Personality    Alcoholism is a road often traveled yet there is no light at the end. The road only leads to a life of depression, anxiety, anger, stress, and much more. These are all common unwanted personality traits that we experience at one time or another. However, alcoholics exhibit these traits day in and day our as the likelihood that they act in these types of manners is nearly doubled when alcohol is involved. Alcohol inhibits not only our daily bodily functions but our mind as well. Alcoholism leads to times of withdrawal, low self-esteem, and an overall unwillingness to be part of society. It can turn the gentlest person into a raving psychopath without them even knowing it or if they do know, they refuse to admit it. Alcoholism manipulates the way we think and the way we react in common everyday situations. Minor problems are blown out of proportion while major problems are faced with anger, resentment, and often physical force. Alcoholism does nothing positive for an individual. It has many harmful effects and its effects on one's personality is one of the most harmful of all.    Our personality is who we are and who we are known as. Alcoholism takes that personality, corrupts it, and turns us into the person we never thought weà ¾d become. As the alcohol becomes more important and necessary in an alcoholicà ¾s life he will find himself unable to any longer answer the question of who he is but will rather find himself asking questions such as who he has become. At first, an individual may enjoy an occasional beer or two to à ¾take a load offà ¾. This does not have a permanent adverse effect on his personality. However, as time goes on, if this same person finds himself relying on alcohol to make it through the day, the problem has started. Before he knows it he will find himself psychologically dependent on alcohol and stages will develop. First, he may need a drink before he goes to bed to make him sleep better. Next, he may need to have a beer or two during his lunch break at the office because he has a lot on his mind. Finally, heà ¾ll find himself dr inking as a means of solving the simplest problem or needing a drink before he can even feel comfortable in public. Once this point in the alcoholic cycle is reached, his personality will begin to change as it takes on a new, distorted shape.

Globalized World Essay

â€Å"The modern Company has spread its brains – its center of excellence. It really is a citizen of many countries rather than a citizen of one†. Do you agree with the statement? I agree with the above statement. The above statement truly talks about the globalization and being in the globalized world. Globalization refers to the increasing unification of the world’s economic order through reduction of such barriers to international trade as tariffs, export fees, and import quotas. The goal is to increase material wealth, goods, and services through an international division of labor by efficiencies catalyzed by international relations, specialization and competition. It describes the process by which regional economies, societies, and cultures have become integrated through communication, transportation, and trade. Talking about the positive and negative side of globalization, it continues to be divisive subject among political activists, academics, business leaders, and policymakers. Some look at the rapid economic and political changes taking place around the world and see injustice. Others observe these same changes and see progress. On both sides of the debate, however, much of the discussion takes place among elites. What do average citizens around the world think about the powerful global forces transforming their societies? Survey research suggests that most people embrace the idea of a globalized world, even if cautiously. Globalization had also increased the competition among different companies in different countries. People are striving to make their countries better and richer. With globalization, there are chances that the developed countries will take over the developing and underdeveloped countries. It is better to take up measures to meet the needs of everyone in order to live peaceful and comfortable life. Some people are finding it difficult to cop up with globalization. With the proper use of modern technology, communication can be made easier and there will be more integration of different companies in the world. The movement of people has also become one of the most important things due to globalization. In the years companies started recognizing and valuing the workforce. They started considering people as assets to increase the productivity. Hiring competent and qualified employees are thought to be the basic ingredient for growth. E. g. Employees of Microsoft come from various different sectors. An organization is a collection of several human and non-human entities. People are different and vary in their thoughts, views, and opinions. An organization tries to hire the best and competent employees through all across the globe. In an organization we can find employees coming from several cultural and socio-cultural backgrounds. So we can say that it really is a citizen of many countries rather than a citizen of one organized together and working together. This has become possible only due to globalization. Hence we can conclude that organizations who thing that the world is a single global network and thereby understanding the fierce competition, lifestyles and culture of different countries will help them to thrive for excellence and ultimately will lead them to achieve their desired goals.

Criminal Profiling Essay

Criminal profiling involves analyzing the scene of a crime and then use the information gathered from the analysis to determine correctly the identity of a perpetrator. This method of identifying perpetrators is very useful though it does not assist an investigator in getting the name of the perpetrator it helps narrow down and thus makes it easier to identify a criminal. (Dennis, 2006) Some of the pertinent issues that criminal profiling helps in bringing out include but not limited to the sex of the perpetrator, the background of a person in terms of ethnic community, age and personality. This profile is then used to single out a criminal among several people who appear to match with some of the features identified in the profile. One may wonder just how does criminal profiling work? Normally experts examine the manner in which a particular crime is committed. This is commonly referred to as the method of operations. Usually the experts will take the identity of the victims and then examine what the suspected criminals have in common especially in terms of the likely weapon that was used to commit the particular crime in question. The other issue that the experts look at is the brutality or hostility that was used during the commission of the crime in question by the perpetrator. Existence of torture or any form of hostility is yet another trait that experts look for when using the criminal profiling method. One student in an American University during a lecture asked her professor why he believed that the criminal profiling method actually works in identifying a perpetrator in a criminal act. The professor gave a precise answer and stated that thorough research has been carried out over the years and there have been conducted some interviews even with convicts who have helped prove the workability of this method. There are two main ways that are used to come up a criminal profile. One of the methods is one that is commonly used by the Federal Bureau of Investigation known as criminal scene analysis. This method involves a number of steps which include profiling inputs. This basically involves gathering evidence in terms of anything that was found in the scene of the crime. The second step usually is to put the evidence together and try to see if there is any common aspect in the crimes committed by the suspects. Crime assessment and investigation follows and it is after that some apprehensions can be made based on the investigations. The second method is the behavioral evidence analysis. This method was developed by Brent Turvey who argued that when a crime is being investigated there are a lot of discrepancies that rise from all the gatherings that are made by the investigative team. The first step is forensic analysis which involves analyzing physical evidenced gathered which may involve taking photographs and videos of the crime scene and having interviews with some of the victims of the crime who may be alive. Victimology is the nest step and involves creating a profile for a victim which in turn helps identify the criminal responsible. The third step is examining keenly the features and characteristics of the scene of crime as this is said to give a leading clue on who the suspect could be. The last step is combining the first three steps discussed and it is this combination that helps the investigators come up with a criminal profile. According to Turvey a crime ought to be analyzed in four main steps to ensure that the information gathered by the investigative team does not bear any discrepancies. Criminal profiling has in several instances been criticized as a source that lacks credibility on the basis that it is based on speculations. However experts state that according to research that has been conducted for several years now, criminal profiling has a considerably high level of credibility. Profiling involves a number of phases. The initial phase in every criminal profiling is known as antecedent which involves attempting to figure out the plan or the fantasy that the perpetrator of a crime had prior to the commitment of the crime. Basically this phase of criminal profiling involves an attempt to unearth the motive behind the commission of a crime by the perpetrator. The second phase is known as method and manner and involves examining the target group that the perpetrator was aiming at in the crime committed and more so the manner in which or better still the method used to commit the crime in question. Brent, 2002) The third phase in criminal profiling is known as body disposal and is common in murder cases. This is where experts attempt to examine where the scene of crime is the same with the place where the body was dumped or whether the crime was committed at a particular place and then the body dumped in yet another place thus introducing the concept of multiple. (Davis, 2007) Post offense behavior is the final or the last phase in criminal profiling and it is quite tricky. Post offense behavior involves investigating behavior of criminals especially after commission of crimes. Normally some criminals try to hide their identity by pretending to be part of the investigating team. Experts must therefore use their expert knowledge to single out criminals who pretend to be assisting in the investigation process yet they are the suspects. Having examined in great depths what criminal profiling is all about, it may be of paramount importance to address the issue of whether criminal profiling has managed to shape up chance. Basically by making this analysis we are able to know whether criminal; profiling does any play any vital role in helping to identify criminals in a given crime in question. In simpler terms using criminal profiling as a method of identifying criminals what are the chances of identifying the suspect responsible in the criminal act at hand. In the beginning of the twentieth century, criminal law took a new twist with criminal profiling slowly shaping chance. Majorly what changed during the twentieth century was the inference in terms of probability. During this century actuarial methods changed. One thing to note that it is not the risk analysis and actuarial thinking that actually changed but the inferences in terms of probability. The actuarial methods got more refined so that using the criminal profiling method one can be sure that the identity of a particular perpetrator is correct. In conclusion therefore it is correct to state that over the year and more so after the twentieth century, criminal profiling is slowly gaining acceptance as reliable method of correctly identifying perpetrators of crimes. This is because it has been studied and proved that it shapes chance so that the probability of a person to be the suspect of a crime in question having been pointed out by the criminal profiling method is very high.

How to Work Full-Time and Fit in Vacations

How to Work Full-Time and Fit in Vacations Joanna Niles, a lifestyle and travel blogger, wrote about traveling while working full time over at the HuffingtonPost this week. I thought her tips were great- practical and strategic- and my husband and I used many of the same approaches when we plan travel a few  times a year. Look at the calendarSince I teach workshops and college-level courses, my schedule is bound by the academic calendar. This means I can travel a lot in early and late summer, I have a lot of time in January, and I always have a few 3- and 4-day weekends during the fall and spring.Chances are if you work for a corporate or government employer, you have a variety of paid and national holidays to make the most of, too. Not every trip is a week-long extravaganza- we’ve done weekend jaunts to San Francisco, Philadelphia, Portland, Maine, and have a trip to New Orleans coming up at the end of the month. It’s surprising how refreshing and enjoyable a brief visit can be. You can also be more efficient with your vacation days by adding on one before or after a long weekend.TelecommuteNormally, you’d be working during the day and perhaps socializing at night. Maybe you can work out an arrangement where you can take that format on vacation with you, too. Another option is to work after the family goes to bed or before they’re up in the morning.This tip has the potential to backfire since you can also be pursued by work long after you’re ready to unplug, but if you’re disciplined about allowing and restricting access (yours, and your coworkers!), a vacation where you spend an hour or two emailing and coordinating in the morning and then go about your day can be great for making your getaway productive.This summer I had to take a pile of grading to the beach, and the first two days of our trip were divided between lounging on the sand and marking up papers on the balcony. Sure, I wanted to be spending more of my time on the boardwalk, but the alternative w as postponing our much-anticipated vacation just for a deadline, so it turned out to be a worthwhile compromise.Plan AheadWhen my husband and I first got together, he hated the way I liked to plan six months or a year out, but now he appreciates that if you don’t get a head start on planning trips, you can miss out on awesome seasonal opportunities or experiences that sell out as soon as they become available to the public.Don’t forget to set aside some vacation time around the holidays! My first year of working full-time, I didn’t anticipate that my company wouldn’t just automatically close on important â€Å"eves.† If my boss hadn’t been generous about commuting my sick time, I would have had a sad solitary holiday weekend alone in my apartment instead of back in my hometown.Be FlexibleThat said, sometimes you have to just get that price alert in your inbox, click through, reserve your flight and grab a weekend bag.

Aboriginal Contributions to Canada - Essay Example Since the time the aboriginals have been living in Canada, they have also been a great source of contribution to the country. They have significantly contributed in the field of agriculture, geography, literature, military, arts, fur trade and medicine. This paper primarily focuses on the contributions of the aboriginals in Canada with regards to medicine. Aboriginal Population Statistics In 2001, there were 3.4% aboriginals who lived in Canada from which 62% were North American Indian while 30% were Metis and 5% were Inuit. The largest populations of the aboriginals in Canada lived manly in the provinces names of which are Ontario, British Columbia, Alberta, Manitoba and Saskatchewan.  However, the projections that have been made with regards to the aboriginal population in Canada tell that there would be 1.39 to 1.43 million people by 2017 and therefore, they would represent 4.1% of the entire population in Canada. Moreover, the population is expected to increase by 1.8% on an an nual basis and this is because of the aboriginal birth rate which is 1.5 times higher than the Canadian birth rate (CBC NEWS, 2006).   Aboriginal Traditional Medicine Traditional medicine plays a very vital role and is an essential for of First Nations health. However, it has not been given much importance by the health care system. A holistic model is used by the traditional medicine and its purpose is to ensure wellbeing by integrating a variety of aspects that include emotional, physical, mental, and spiritual aspects. Although there is a variation between the specific tribes, all tribes practice medicine on the belief that man is a part of nature, and health should be balanced. This is the reason why land and its offerings are respected. Importance of using environment for foods which were traditional and medicines was understood by the traditional elders. Today, there are many alternative medical models that analyze health and body like traditional medicine did. Moreover, sam e philosophies are followed by alternative medical models which relate to well being of the human bodies and the environment (FNHC, 2011). There are various principles philosophies with regards to the treatment of whole person which include body, mind as well as spirit through health and well being. Things such as plant, animal and mineral are used to make medicines. Moreover, the aboriginals have passed their knowledge and expertise to their future generations that have developed the ability of diagnosing and treating various conditions. Therapies such as â€Å"Naturopathic Medicine† can be accessed and can be used as alternative to conventional care. However, the federal government of Canada does not fund traditional medicine. In certain situations when individuals visit practitioner of alternative medicine are covered but naturopathic physicians do not bill the government. This is the reason why it has become challenging for the patients to opt for health care which they p refers. Besides this, it has also become challenging for the clinics who need to hire the traditional healers (Elias, 1991). It was known to the women in the first nations which included the Inuit and the Metis that traditional healing can play a great deal for us, our families as well as for our communities. Since traditional healing is important, the government of Canada has also recognized it. Although aboriginal medicine is becoming more and more important, there are still a lot of improvements that need to be made. Traditional healing provides treatment to the mind, body as well as the spirit. This approach is very much

The United States Embargo on Cuba Research Paper

The United States Embargo on Cuba - Research Paper Example It was the year 1492, when Christopher Columbus had sailed out to the ocean blue. He came across an island which was enriched with beauty so fascinating that he had never seen it before. As years went by, the Island of Cuba gradually developed into one of the most booming and substantial Latin American nation with specialties like lush plantations, coffee and its all time favorite tobacco. However, on the other hand, for almost a period of 50 years, the Caribbean nation has continuously been engaged in this courageous battle that involves its super power neighbor, the United States of America.1 In an ongoing effort towards the so called nationalization of private property in Cuba, America has performed one of the longest travel and as well as economic blockades against any specific nation. Finally after passing away of a 50 year’s milestone, global community seems to be almost united with a belief that these sanctions against Cuba have actually failed drastically. A step furth er, the world is now wondering as to why these American policies continue to this day. To gain a full understanding to the conflict between the United States and Cuba, we must talk about the situation that prevailed well beyond this recent 50-year deadlock and analyze aspects that emerged after the Spanish-American War. In 1898, Cuba emerged as a territory of the US, along with Philippines, Guam and Puerto Rico. Not much time had passed that in the year 1902, Theodore Roosevelt who was then the US President permitted Cuba to declare its independence as a free state. However certain terms and conditions were applied. He made an agreement with the new formed government, securing two of the major advantages. One, America holds the right to oversee Cuba’s financial and international affairs. Two, he also asked for leasing of a naval base located at Guantanamo Bay.2 As we further look into the provisions and focus on the enlarged scope of the embargo, it is noticed that the United States had placed its initial sanction and restriction on the country, Cuba in the year 1960. This was done via restrictions placed on the importations of sugar cane from Cuba. This first sanction was imposed as an answer to the step taken by the Cuban government of nationalization of foreign assets as well as other organizations. This angered the United States as most of these businesses belonged to the citizens of the United States. Since then, the US government authorities have extended such sanctions against Cuba. As a result, today it can be observed that the trade embargo has eventually broadened into an entire comprehensive set of financial, economical and commercial sanctions which are documented within regulations such as Act of 1917: Trading with the Enemy, Act of 1961: Foreign Assistance, Assets Control Regulations of Cuba (1963), Cuban Democracy Act (Torricelli Act 1992), The Trade Sanctions Reform (2000), and the 2000 Act of Export Enhancement.34 Several other sanction s and restrictions were further imposed due to which this Cuban embargo is known as a â€Å"comprehensive set of US sanctions† imposed on a nation. The restrictions that were imposed in the embargo had major impacts on the social and basic rights of people. This set of so called laws helped towards deprivation of Cuba from availing technological developments, medicines, substances for purifying water, food as well as electrical power. Not only this, economic rights were also neglected and added to the negative impact of the embargo. It extensively affected the environmental and socioeconomic aspects of
