Kirkpatrick Model of Training free essay sample
Donald Kirkpatricks 1975 book Evaluating Training Programs defined his originally published ideas of 1959, thereby further increasing awareness of them, so that his theory has now become arguably the most widely used and popular model for the evaluation of training and learning. Kirkpatricks four-level model is now considered an industry standard across the HR and training communities. The four levels of training evaluation model was later redefined and updated in Kirkpatricks 1998 book, called Evaluating Training Programs: The Four Levels.

Despite the complexity of the statistical databases’ protection, there are diverse sorts of mechanisms which can keep out the confidential data. This report discusses methods as data perturbations, query restriction methods and differential privacy which provide privacy in the statistical databases. Keywords: statistical databases, privacy, input perturbation, output perturbation, differential privacy. 1. Introduction Nowadays, there is a wide-spread access to data. Having a lot of advantages to omnipresent access of information, there is also the possibility to break the privacy of individuals. In the statistical databases, personal data with very large number of individuals is stored. The statistical databases contain multiple statistical information. They give to their users the ability to acquire this information and also to protect the privacy of individuals. However, supporting security in the statistical databases against the revealing of confidential data is complicated and ambitious task. This problem of privacy in the statistical databases has expanded in the recent years. This report will examine the main methods for providing privacy in the statistical databases.  2. Body 2.1. Definition of statistical databases A statistical database is a set of data units which has permissive access to the statistical information connected to these data parts. The statistical database could be described as a database system which allows to its users to obtain only aggregate statistics for a subset of items introduced in the database [1]. The statistical database posses limited querying interface which is restricted to operations such as sum, count, mean, etc. The statistical database also could be defined as query responsive algorithm which permits the users to access the content of the database through statistical queries [2]. The statistical database is concerned with the multidimensional datasets and is related to the statistical summarizations of the data sets’ dimensions. The statistical database is mainly oriented to socio-economic databases which are normally the field of statisticians. An example of statistical database is the census data which is linked to collection of information about the assessment of the population trends. Another example of statistical database is the economic database which includes statistics for the industries’ sales and income or statistics for the use and production of diverse products [3]. 2.2. Privacy in statistical databases The privacy can be described as the right to specify what type of information about individuals or items is allowed to be shared with others. The benefits from analyzing the statistical database are very significant but the release of the information from this database could cause a lot of problems, troubles and damages. Thus, one of the main aims of the statistical database is to ensure privacy of the information. To be an effective statistical database, it should protect all its records [4]. As the statistical database should provide statistical information, it should not disclose private information on the items or individuals it refers to. The releasing of a statistical data may offend the privacy rights of the individuals. Therefore, the statistical database should follow some ethical and legal behavior to defend the individuals’ records. For legal, ethical and professional grounds, the users of the statistical database are not authorized to receive special information on individual records. The statistical database should protect the sensitive information allowing its users to get aggregate information. The restricted access should be permitted either from the point of view of the groups of people to whom this information is available or from the point of view of the certain aspects of this information. However, it is possible sometimes when statistics are correlated, the sensitive information to be inferred. If a combination of aggregate queries is used to obtain information, we say that the information in the database is compromised and therefore the database is also compromised [5]. The main duty for the privacy of statistical database is to find appropriate methods which could ensure that no queries are sufficient to infer the values of the protected records. 2.3. Methods for providing private statistical databases The following methods and techniques are used to secure the privacy in statistical databases. 2.3.1 Perturbation methods There are two main perturbation methods for preserving privacy in statistical databases. The first one is the input perturbation where the primary data is randomly modified and the results are calculated based on this modified data. The second perturbation method is the output perturbation which computes the results from the queries exactly from the actual data [6]. In other words, the input perturbation is detected when the records are computed on the queries while the output perturbation is applied to the query result after computing it on the original data. The perturbation methods look for accomplishment of the masking of item or individual’s confidential information while trying to maintain the basic aggregate relationships of the statistical database. One of the main aims of these methods is to ‘conceal’ particular confidential record. It is also necessary to notice that the perturbation techniques are not encryption techniques which first modify the data, t hen usually send it, receive it and finally decrypt it to the original data. The primary difficulty of these methods is to assure that the introduced error is within the satisfactory limits. There is an exchange between the level of protection that could be attained and the variance of the presented perturbation. 2.3.1.1 Input perturbation The fundamental idea behind this method is that the result which is returned by the queries is based on a perturbed data. This means that the primary data in the statistical database is not used to create query results. One side that is necessary to be taken into account is the duplicated database. This database, which is used to turn back to results, must maintain the similar statistical characteristics as the original database. This technique introduces random noise to the confidential information and thus protects the data. Adding statistical noise in the database makes the input perturbation an important method in the enhancement of the privacy. The original database is generally changed into modified or perturbed statistical database which is afterwards accessible to the users. The input perturbation permits the users to access the necessary aggregate statistical information from the whole database when it makes changes to the original data. Therefore this process helps to protect the records [7]. The records of the database contain values that are variations of their adequate values in the true database. As a whole this method tries to minimize the severe bias in the query results by allocating the corresponding bias in the data so that it could cancel out in the huge query sets. In the input perturbation, the data is perturbed for instance via swapping attributes or adding the random noise before this data releases the whole statistical database. There are two well-known subcategories in the input perturbation. The probability distribution interprets the statistical database as a sample from a given data that has a certain probability distribution [1]. The main purpose is to transform the primary statistical database with a different sample which is from the same probability distribution. This input perturbation creates a substitute database from the original one. This method is also called data swapping. The second subcategory is the fixed – data perturbation where the values of the records in the statistical database are perturbed only once and for all the records. Since the perturbation process is done only once, the repeated queries have consistent and logical values. This perturbation also constructs an alternative database as the probability distribution. This alternative database is created by changing the value of every record by a randomly produced perturbation value. The fixed – data perturbation could be applied to both numerical and categorical data. 2.3.1.2 Output perturbation The output perturbation differs notably from the input perturbation. In the input perturbation, the data is specified by all statistical features of the database. As longs as in the output perturbation, the perturbed results are directly introduced to the users [8]. Another difference is that in the output perturbation, the problem with the bias is not as harsh as in the input perturbation. This is because the queries are based on the original values but not on the perturbed ones. The output perturbation method is based on calculation of the queries’ responses on the statistical databases. This method adds the variance to the result. The result is produced on the original database however the noise is added to the result before to return it to the users. As the noise is not added to the database, this method generates results that include less bias that the input perturbation. It is necessary to note that if the noise is random then this noise could be reduced by performing th e same query over and over again. Some limitations exist. For example if there is very large number of queries to the statistical database, the amount of the noise added to the results should be also very large [9]. The output perturbation has pretty low storage and computational overhead [10]. This method is rather easy to carry out because it does not influence the query process. The output perturbation consists of different approaches as random sample queries, varying output perturbation and rounding. The random sample queries technique shows a technique where a sample is created from the query set itself. The random sample queries method denies the intruder accurate control which covers the queries records [11]. One drawback of this method is that it could not ensure enough certainty for users to prevent the confidential data. However, the random sample queries may present precise statistics for number of records. The USA Census Bureau for example mainly works with this technique to restrict the inference in their statistics records. Every reported query is founded upon a gratuitously chosen subpopulation of the query set. The USA Census Bureau is satisfied with this method and applies it very successfully in its activity. The second approach of the output perturbation is the varying – output perturbation [1]. This method is suitable for the SUM, CO UNT and PERCENTILE queries. The varying – output perturbation presents a varying perturbation to the data where random variables are used to calculate the answer to a variant of a given query. The last approach of output perturbation is the rounding where all queries are computed based on unbiased data. Afterwards the results are transformed before they are returned to the users. There are three types of rounding – systematic rounding, random rounding and controlled rounding [1]. It is advisable to combine the rounding method with methods to provide more privacy in the statistical database. 2.3.2 Query restriction method The main idea of this method is even if the user does not want to receive deterministically right answers, these answers should be exact, for example numbers. As these answers to queries give the users forceful information, it might be important to deny the answers of some queries at certain stage to prevent the disclosure of a confidential data from the statistical database. The type or the number of queries that a user puts to the statistical database is restricted. This method discards a query which can be compromised. Nevertheless, the answers in the query restrictions are always precise. It could be concluded that the restricted group of the accepted queries considerably reduces the real usefulness of the statistical database. This method provides a protection for the statistical database by limiting the size of the query set, by controlling the overlap among the consecutive queries, by maintaining audit of any answered queries for every user and by making the small-sized cells inaccessible to users of the statistical database. There are five subcategories of the query restriction method – query set size control, query set overlap control, auditing, partitioning and cell suppression [1]. 2.3.2.1 Query set size control method The query set size based method declines the answers to queries which have an influence on a small set of records. Fellegi [12] sets lower and upper limits for the size of the query answer which are based on the characteristics of the database. If the number of the returned records is not within these two limits, the request for the information could not be accepted and therefore the query answer may be denied. The query set size control method can be explained by the following equation [12]:                                        K ≠¤Ã‚ |C| ≠¤Ã‚ L – K,                                                                 (1) where K is a parameter set by the database administrator, |C| is the size of the query set and L is the number of the entities in the database. The parameter K must satisfy the condition [12]:                                                             0 ≠¤  K ≠¤Ã‚                                                              (2) The main advantage of this method is its easy implementation. However, its robustness is low so it is advisable to use it in a combination with other methods. 2.3.2.2 Query set overlap method The query set overlap method permits only queries which have small overlap with formerly answered queries. Thus, the method controls the overlap over the queries. The lowest overlap control restrains the queries responses which have more than the predetermined number of records in common with every previous query [3]. This surveillance is valuable in the defense against  the trackers as a compromise tool. In spite is all, this method has some drawbacks [13]. This query set overlap control is not enough effective when several users together try to compromise the statistical database. As well as the statistics for both a set and its subset are hard released which limits the efficiency of the database. 2.3.2.3 Auditing The third subcategory of the query restriction method is the auditing. It requires the maintenance of up-to-date logs of all queries which are made by every user. It also requires a continuous check-up for potential disclosure whenever a new query is published. One main advantage of this method is that it permits the statistical database to support the users with unperturbed data and ensure that the response will not be compromised. A disadvantage of the auditing method is its excessive CPU and the requirements for the storage and processing of the collected logs [1]. 2.3.2.4 Partitioning The partitioning method groups the individual entities of a population in a number of reciprocally excessive subsets, known as atomic populations. Therefore, the records are stored in groups which consist of predetermined number of records [4]. A query is permitted only to the entire groups, but not to a subset of a group. The statistical features of these atomic populations form the raw materials which are attainable to the database users. While the atomic populations include exactly one individual entity, a high level of protection can be achieved. A research, taken by Schlà ¶rer, found that there is an emergence of the large number of atomic populations with only one entity. The result of this will be a considerable information loss when these populations are clustered. One major drawback of this method is the retrieved value of the statistical information. When the database is partitioned, the statistical data is toughly obscured. This restricts the flow of potential wanted stat istical information by the users. In reality, the users may not have the chance to acquire the desired information. 2.3.2.5 Cell suppression The cell suppression method is frequently used by the census bureau for information which is published in tabular form. This technique protects the tabular data from a compromise. The main idea is to conceal the cells that can lead to a disclosure of a confidential data. In this way, the cell suppression minimizes the suppressed cells with private information. These cells are called primary suppressions. The other cells with non confidential data, which may be a threat and lead to a disclosure, should also be suppressed. These cells with non private information are called complementary suppressions. These complementary suppressions provide a pre-defined level of protection to the primary cells. 2.3.3 Differential privacy As Dalenims (1977) points out that an access to a statistical database should not be allowed to a user to acquire information about an individual’s record which cannot be found out without the access of the database. This form of privacy is difficult to be achieved because of the auxiliary information. The auxiliary information is information which is available to the adversary without an access to the statistical database [14]. For example, let presume that one’s exact weight is considered as highly sensitive information and revealing this information is regarded as a privacy break. Next, it is assumed that the database provides the average weights of people of different nationalities. An adversary of the statistical database who has an access to the auxiliary information, that a particular British person is 10 kilogram thinner than the average French person, can learn the British person’s weight, as long as anyone gaining only the auxiliary information with out having an access to the average weights, learns not much [15]. This leads to the application of the concept of differential privacy. In spite of the fact that the differential privacy does not exclude a bad disclosure, it ensures the individual that his or her data will not be included in the database that produces it. The differential privacy is defined as one of the successful methods of providing privacy for the statistical databases. The basic description of the differential privacy is that it is focused on providing ways to increase the accuracy of the queries from the statistical database while trying to minimize the chances of recognizing its records. The differential privacy is a randomized algorithm which accepts the database as input and generates an output [15]. A more precise definition of this method is the following formulation: A randomized function K that gives à µ-differential privacy if for the databases D1 and D2, which only differ on at most one element and all S⊆Range (K), Pr [K (D1) ∈ S] ≠¤ exp (à µ) x Pr [K (D2) ∈ S]                             (3) When this function K satisfies the above definition, it can ensure an individual that though this individual removes his or her data from the database, the outputs cannot become indicatively more or less acceptable. The differential privacy strives to guarantee an adjustment to the statistical disclosure control’s problem. The differential privacy aims to publicly let out statistical information relating to a set of individuals without allowing a compromise for privacy. This method demands that there is an inherently the same probability distribution on the produced results. This probability distribution should be independent of whether each individual chooses or not the data set [16]. This process is done indirectly as at the same time it addresses all potential forms of harm and good by concentrating upon the probability of every given output of a privacy method and upon the ways for changes of the probability when any row is added or deleted from the database. The statistical database is usually developed to reach social goals and the expanded participation in the database allows more precise analysis. Therefore, the differential privacy assures the support for the social goals by guaranteeing every individual that there is a quite little risk by connecting to the statistical database. The differential privacy has some advantages. Firstly, this privacy preserving method is independent of any extra and auxiliary information including also other databases which are available to the adversaries. Secondly, the differential privacy is easily implemented through the using of rather sample and general techniques. The last advantage is that the differential privacy usually permits very accurate analysis. 3. Conclusion To conclude, the statistical database provides to users statistical information for values which are based on various criteria. The field of the statistical database is highly important because it encompasses a broad variety of application areas which in principle deal with great amount of data. This statistical database may consist of confidential data which should be protected from unauthorized user access. It is very important to provide a precise statistical database with professional, legal and ethical responsibilities for privacy protection of the individual records. Providing security in the statistical database proves to be a complicated task. There is no single solution to this problem. Therefore, numerous methods and techniques are suggested to be used to ensure privacy in the statistical database. The analysis presented in the report shows that the perturbation methods, the query restriction methods and the differential privacy are clearly among the most promising methods for the private statistical database.

Watching TV - Essay Example For that reason, it keeps people more aware of their surroundings making people smarter when it comes to solving societal issues. Therefore, in my opinion TV makes people to be intelligent. This argument is in agreement with Steven Johnson essay†watching T.V makes you smarter.†The choice of material that people choose to watch on television is what matter in relation to the intelligence it is going to add on that person. For example, shows like Simpson have an entertaining aspect while at the same time has quality of morals and knowledge that it shares with it viewers. For that reason, most people who spend their time watching the Simpson get to grasp knowledge what the show is trying to bring out (Johnson 170). Furthermore, the shows targets the average American so promoting the life of a middleclass American. By so doing, it encourages individuals who watch the show because they know that there is a person who understands what they are facing each day, hence adding and intellectual advantage. Moreover, television has its advantages when it comes to the group of people it wants to target. The television shows that are aired have an age bracket meaning that the content that is aired for children adds some intellectual value. For example, tellytubbies and other cartoons act as a good method to measure the children intellectual capability to establish whether they understand the content. Thus, although the content is entertaining it also grabs the attention of the children meaning that at the end of the show they will have achieved something. Furthermore, television acts as an intellectual advantage because it promotes many possibilities such as higher learning, as well as, providing entertainment (Johnson 175). For example, when watching a documentary a person get to understand many thing and by seeing the visual pictures on the documentary makes them more alert; hence, acting as a great source of gathering

Echo Planar Imaging, or EPI, Fast Imaging Techniques (MRI) Essay - 1
Echo Planar Imaging, or EPI, Fast Imaging Techniques (MRI) - Essay Example Different results have been found from different body areas which have varying magnetic field strengths thus such body areas end up having varying processional water frequencies. Blood has been observed to have the highest susceptibility as it has iron contents as one of its components. Compositions based on water also have high susceptibility in comparison with air (McRobbie 2007) (a) List the parameters that could be changed to optimize the EPI image in this case, plus how you would change the parameter (i.e. increase or decrease). (2 marks) Slew rate and the receiver bandwidth Each of the listed parameters has a different way of changing it. For example, the case of slew rate increment, an overall reduction in echo spacing as well as reduction in geometric distortion is required for it to be altered. For receiver bandwidth to be increased, an overall reduction in echo spacing, signal to noise ratio and geometric distortion need to be lowered (Van Der Zwaag, at el. 2012, p. 129) In a normal scenario, MR equipments take their time until the trapezoid gradient gets to the flat top. When this time comes, the data points will then be sampled by the MR equipments in the direction of the frequency. This implies that no data acquisition takes place during the rise time. The rise time refers to the time when the gradient is not yet at its minimum or maximum amplitude. However, by employing ramp sampling method, the data points witnessed during the readout gradient switching can be acquired during the rise time. a) Two different features can be used while employing ramp sampling, and they include; 1. Having the geometric distortion minimized; ramp sampling can be used to reduce the flat top while at the same time keeping the Nx constant. This implies that the echo spacing can be decreased consequently minimizing geometric distortion. 2. Increasing resolution; by keeping the flat top at the same level, more Nx data points can be fitted during readout and thus increasin g the overall resolution. b). Using Conjugate Synthesis; Conjugate synthesis is a symmetry property which means that only half of the raw data spaces in the whole MR can be acquired to come up with a Mr image that is complete. The most desirable means to achieving high resolution during a single shot EPI experiments is through having the readout duration on the ky to be as long as possible so as to have only the negative and positive kx values. c). Slew rate enhancement d). Echo train length reduction e) Making use of shimming to minimize distortion d). Employing parallel imaging to minimize echo spacing f) . Making use of Multi shot EPI so as to ensure that there are no cases of phase errors building up. g). Through increasing the TE which will in turn increase the transverse magnetization hence larger T2* and T2 (b) Discuss the chain of consequences if you optimize the image by increasing the receiver bandwidth. (4 marks) Receiver bandwidth generally describes how fast an MR signa l can be digitized. In cases where the receiver bandwidth is generally higher, there is a corresponding faster digitization of the produced image. This is because the aspect of receiver bandwidth is inversely proportional to the time taken during the imaging process. The receiver bandwi

European union Essay Example | Topics and Well Written Essays - 1000 words
European union - Essay Example In addition to this, public law involving the commerce in European Union has fundamental significance:2 i. Most of the laws governing ECJ commercial circles whether directly or indirectly, are grounded on the European Union Laws ii. The framework which governs private businesses is widely derived from the rules that were established in 1957: that is, The Rome Treaty iii. Most of the sections of the regimes ruling and providing guidance and direction are either prescribed to European Union Regulations or largely affected by the â€Å"sectoral†agreements reached upon by the states in agreement. The reference of the aforementioned views are made to the C-213/89 Factortame (No1) [1990] ECR I-2433 Case 11/70: a case that involve the controversy in the fishing policy that were change in British. The fishing policy which started iin early 1970s was intended to make fishing within the EU member state of more economicvalue by giving people the liberty to access water freely in within the member states. The common fisheries policy of the European Union also was providing funds to make fishing modernized to meet the market demands. Becase of the increasing demands for fishing in the member states, the EU came up with another agreement in1980 with Spain on to allowance of the fishing agreement which defined to level of fishing grounds and the access points of fishing in the British grounds. As time advanced, the British felt a little uncormfortable with the magnitude of fishing that was taking place in their waters. Fishermen from Spain and elsewhere in the European Union started taking advantage of the fishing vessels that they had to penetrate the UK waters. This led the British to enacting various laws to curb this situation. The British law wanted that the only people who could fish on their water were to be those who were qualified: of which those who were qualified were the British citizen and a company registered in Britain whose 75% members were Brish citiz ens. This move sparked the heat of debate that led the major owners of the fishing vessels from Spain to seek the redress of the law. The people who were affected most were the Factortame from Spain. Their vessels could not meet the conditions that were set by the British newly established laws. The first aurgument advanced by the Factortame was that the British act of 1988 was offensive and could not be applicable to them. They made their reference to the EU law and the Treaty of Rome article 7 which scheduled that one ought not to be discriminated against on the grounds of race, gender and the nationality. According to the EU laws, they had the right to establish themselves in business anywhere and their company could be operative and situated in a nother member country. In general, the approach given to the ECJ to the administration of law, putting up a common honor and alignment to the framework of observance to the general rule of the community law, include values of the intern ational law and guarding the basic rights, is now more to the knowledge of the EU judges. The influence of human rights has made the standard approach in the judicial to grow very rapidly. Upon the investigation and consideration of the structure of the constitution of the European Union, and the numerous changes that have occurred in is so far, its basic structure can be categorized under three broad and general positions3.

Media Essays Media Violence Society
Media Essays Media Violence Society Media Violence Society Media violence has been one of our biggest problems in our community. Violence comes from every age, from a child to an adult. Violence has increased every year because people do not understand how important our life is and do not take it serious. Media violence occurs when people do not have common sense and do not take responsibility. There are couple cases that think that media violence causes society violence, and two against it. Most cases of media violence come from movies, games, and the influence people have on others, all of which have shown someone or something crucifying anything in its path. Those are some ideas about media violence throughout our society. There are two people whose lives were only about killing; it was as if it was in their nature. Stone’s most controversial film, â€Å"Natural Born Killers†was mimicked by murderers Ben Darras, and Sarah Edmondson. Darras and Edmondson have killed over fifty two people and, in the course of their actions have become media celebrities. Both of them have a history in their life that is unforgettable. The public made this inconclusive accusation despite the troubled past of both of the offenders. Oliver Stones said â€Å"Ben and Sarah are deeply disturbed youths with histories of drug and/or alcohol abuse and psychiatric treatment. Ben’s alcoholic father divorced his mother twice, and then committed suicide. Sarah carried a gun because she feared that Ben would attack her†. Obviously, there were many factors inducing their criminal behavior further more complicated than just watching a movie and doing what you have just seen. Many cases like this one have bee n pointing fingers at movies for the actions of disturbed youths, doing so is a ridiculous attempt to find a quick answer to an excessively complicated matter. Michael Zimecki believes that â€Å"ideas have consequences†and that is why the ideas expressed in a movie have a negative effect on society. To support his opinion he uses several examples of crimes that have been committed in the past and are similar to movie scenes. For example in 1993 a 9 year old girl was raped with a bottle at the beach by a group of juveniles, this incident was believed to be induced by the movie â€Å"Born Innocent†where a plunger was used to rape a victim. A boy from Pennsylvania died from imitating a movie called, â€Å"The Program†. He died in the center lane of a highway where he got ran over by a car. Michael Zimecki also uses a different approach to support his theory, he compares movies to pollution. He states â€Å"a polluter should not be allowed to escape responsibility for his actions simply because environmentally induced cancers are late-developing. Violence too, can fester for years†. Zimecki believes that societal violence is displayed excessively and needs to come to an end he asserts â€Å"the hour has come at last, and the rough beast that the poet William Butler warned about is already born†. Some kids think that it is â€Å"cool†to do what happens in the movies, but sometimes what happens in the movies is not safe. Movies can change people’s behavior and personality. Violent movies promote the minds of young kids who do not know what they are doing, but they get hurt in the process of poisoning their minds. Rated â€Å"R†movies that show killing and blood are the movies that kids are not suppose to see, but those kids that do are the ones that change because they think that it is â€Å"cool†to kill people, so they try it. Killing has lead to family separation, rising of violence with in the family, and in the society. That is what happens when these children try to do what they see without knowing if it is possible in real life. Gregg Easterbrook has been working for the New Republic for the past four years and has written magazines of beliefs and values. Easterbrook states that â€Å"movie and television violence has a serious effect on childrens propensity to behave violently later in life†. This theory has been question for years and it still is, but still many people have found connections between media violence and societal violence. At the age of nineteen is when the mind of children has developed enough to know that violence is never the answer and that all kids are doing is hurting them selves. Many kids below the age of nineteen may think that is normal to act in a violent way and becoming juvenile prisoners. There are many movies that people have seen that show a very high amount of violent and blood like the movie â€Å"Scream†. This movie starts by a teen girl watching her boyfriend getting punished. Thought out the whole movie students get hung, tortured and cut to death. Movies li ke this can encourage children to do the same thing since they find what they see very amusing. Many people have died from others mimicking what they have seen in the movies and have been killed or sent to jail for a very long time and won’t be coming out any soon. Maggie Cutler has seen media violence and has ideas of what has happened through out the years. Cutler said, â€Å"Media violence is a risk factor that, working with others, can acerbate bad behavior†. She affirms with the idea of aggressive and brutal matters that have multiplied within the United States. Crime rates of juveniles have decreased about thirty percent in the United States. The media has been reducing the principles for accepting profanity. Further more, Cutler points out that â€Å"given the overall juvenile crime count in 1997 the report implied, some 250 murders and 12,100 other violent crimes would not have been committed if it were not for the likes of Batman Beyond†. She comments that on August of 1999 a Senator reported that â€Å"television alone is responsible for 10 percent of youth violence†. Cutler believes that this subject is too complex to study conclusively. There are some facts and ideas of what our nation has turned into with in th e years. Scott Barbour strongly believes that media violence does not cause societal violence in teens. He supports his idea by stating that laboratory tests cannot be generalized to the real world. Barbour believes the teenagers’ results may be influenced by the adult researchers, he quotes Durkin associate of psychology â€Å"Even quite young children are good at working out what adults want them to do, or will let them get away with.†Another testing method he implies is invalid is correlation studies. Barbour suggests that the results cannot be taken into serious consideration because â€Å"it could just as reasonably be argued that viewing violent television programs is caused by the child’s preexisting tendency to be aggressive†. He also quotes Jonathan Freedman psychology professor at The University of Toronto when comparing boys’ tendencies to girls’ tendencies in relation to personality characteristics. Boys watch and play football more than girls do, and it is not because television influences them to, it is because of personality characteristics. Barbour believes that a child’s violent personality is induced by bad parenting. Stuart Fischoff is a professor of psychology at California State University, Los Angeles. Fischoff has studied media violence and real-world violence and cannot find a connection between them. Nothing states that media violence causes societal violence. He believes that anyone who studies media violence can have a thought of what people may do in the real world; it is not proven that everyone will do it. It is up to how people think, how they can take certain things, and if their common sense can change their life in a good way or ruin it by doing the wrong. Many people that are against media violence think that â€Å"The plethoric effluence of screen violence, murder and mayhem is an undisputed menace to society†. That is what the opposing side has to say against what many people think about media violence. In Conclusion, media violence has taken place since the day we were born, but it has grown by the years mostly because of the messages sent out to the public. Movies reach people who do not know what their purpose in life is, so they go do the first thing they like or see. It starts off by imitating a movie people enjoy, then killing people who have done nothing to you. It can also be that you have an immature mind that has not grown into what would let you realize common sense. People have observed and realized that our humanity has been taken over by what most people would find most entertaining but deadly to perform at the same time. Some people may think that media violence is not connected to societal violence because they have the proof that we have. That is why people think media violence has been one of our biggest tribulations in the world. Works Cited OConnor, Tom: Environmental Factors Contribute to Juvenile Crime and Violence.

The Limits of Narrative in in Joseph Conrads Heart of Darkness Essay
The Limits of Narrative in Heart of Darkness  Early English novelists depicted a very general reality; that is, what many observed to be "real" is what found its way into the narratives. For example, several novels of the eighteenth and nineteenth centuries emphasize, or entirely revolve around, the idea of social status. Samuel Richardson's Pamela addresses a servant's dilemma between her morals and low social position; the hero of Henry Fielding's Tom Jones must also confront his "low birth." Jane Austen famously portrayed class struggles in nearly every one of her novels. These texts all represented the world at its face; the actions of the characters spoke for their "reality," and the narrator was simply the descriptor of these events. The novels conformed to a very narrow world-view, limited by popular thought. True, there was much to explore within this confinement, as shown by the range of commentary in the texts. Still, as stories they could only offer what society observed: a kind of reality by consensus. As Joseph Conrad's Heart of Darkness demonstrates, modernism rejected the aims and methods of realism, and claimed the inner self represented the real more closely than the public world. Furthermore, realism appeared to represent the world wholly and concisely. Conrad's novel rejects this, and instead exposes the failure of language to describe a complete reality. In Heart of Darkness, Marlow himself is incomplete, and so is his narrative. He is forced into imprecise language, resigned to using negative modifiers and repeating inexact words. He struggles to tell his story satisfactorily, and by his own admission, his telling is deficient. The limitation of language, then, becomes the focus of t... ...e rejection of nineteenth century realism. Since Marlow the storyteller is flawed, his story falters as a result. The novel effectively reduces each to their flaws, but does not attempt to hide its limitations behind a manufactured authority. It is this absence, or seeming absence, of controlled writing that brings Heart of Darkness closer to "the real" than any authoritative work of realism.  Works Cited Conrad, Joseph.
