Great Train Robbery Essay Example for Free

Great Train Robbery EssayHenry Hill, the character of Martin Scorseses necessitate Goodfellas (1990), used to say As far back as I can remember, Ive always wanted to be a gangster . The reason of the crime withdraws and gagnster icons being of success with a public partly lies in this sublimated desire of an ordinary man to be as powerful, energetic, and famous as the criminals commemorated in mass-media. Rafter (2000, p. 3) explained the popularity of the genre by its fictional possibilities crime movies offer us contradictory sorts of satisfaction the reality of what we fear to be true and the fantasy of overcoming that reality the pleasure of entering the neighborhood of the forbidden and illicit and the security of rejecting or escaping that realm in the end. The crime film is traditionally associated with the American tradition of the early twentieth century, when romantic tales around heroes conquering promising spaces of the New World prairies were superseded by the not a less romantic sagas about daring individuals conquering updated urban localities.Shadoian (2003, p. 3) referred to the crime film as a prominent context for both forming and reflecting the American imagination. Audience has been enjoying crime movies since 1903, when Edwin S. Porter shot his Great Train Robbery. More than a hundred years of our experience with the crime film taught the public, critics, directors and producers many lessons. Shadoian (2003, p.3) identified three reasons for the genres longevity (1) the issues it addresses befool always been central to the American experience (2) its formal properties have given them a clarity of outline and lucidity of exposition and (3) it has been infinitely flexible in adapting itself to shifting social and heathenish conditions. But hardly is it absolutely right to emphasise the importance of the crime film for the American culture exclusively. The present dissertation analyses thirteen films made within the crime movie c ontext.Only six of them were produced by the USA-born directors (1) William A. Wellman (1896 Brookline, Massachusetts, USA 1975 Los Angeles, California, USA) The Public Enemy (1931) (2) Raoul Walsh (1887 New York, New York, USA 1980 Simi Valley, California, USA) The Roaring Twenties (1939) White Heat (1949) (3) Martin Scorsese (b. 1942 Queens, New York, USA) Goodfellas (1990) Gangs of New York (2002) (4) Quentin Tarantino (b. 1963 Knoxville, Tennessee, USA) cornmeal mush Fiction (1994).Though the film Brother (2000) is partially made in the United States settings, its creator is a famous Japanese director Takeshi Kitano (b. 1947 Tokyo, Japan). He is alike responsible for another example of the crime movie, Hana-bi (aka Fireworks 1997). The other five films under analysis belong to the British directors (1) trick Boulting (1913 Bray, Berkshire, England, UK 1985 Sunningdale, Berkshire, England, UK) Brighton Rock (1947) (2) Mike Hodges (b. 1932 Bristol, England, UK) Get Car ter (1971) (3) John Mackenzie (b. 1932 UK) The Long Good Friday (1980)(4) Jonathan Glazer (b. 1965 London, England, UK) Sexy Beast (2000) (5) Paul McGuigan (b. 1963 Bellshill, Scotland, UK) Gangster No. 1 (2000). It would be more correct to identify the reasons for the crime film being a success outside the boundaries of issue mentalities. Leitch (2002) based his definition of the crime film within the conceptual context of culture rather than the national background. He (Leitch 2002, p. 14) argued that, a crime culture depends on normalizing the unspeakable, a place where crime is both shockingly disruptive and completely normal.Crime may have different metaphorical valences in different criminal subgenres it can demonstrate the fragility of the social contract in thrillers about innocent men on the run, attack the economic principles of the establishment in gangster films, express philosophical despair in films noirs, test masculine professionalism in private-eye films bu t it is always metaphorical. every crime in every crime film represents a larger critique of the social or institutional order either the films critique or some characters.Finally, crime films dramatize not only the distinctive roles of criminal, victim, and avenger but also their interdependence and their interpenetration. Evidently, critics and spectators are lured to the genre by its flexibility and visual image of the concepts otherwise unseen or too repulsive to deal with in ordinary life. It is hypothesised that national mentalities affect the themes of crime movies but generic methods of the crime film depend rather on directors individual backgraounds rather than on their nationality.

Ethan from - Realism Essay Example for Free

Ethan from Realism EssayThe rise of Realism in 1855 was the time when farming began to industrialize, communication expanded through railroads, and Nationalism was yet once again revived. On top of all these important transformations that have marked this period of time was the significance for writings with a new audience, new settings, and new characters. The novel, Ethan Frome, by Edith Wharton, is a magnificent example of literature from the Realistic period. First, Realism is a definite movement away from the Romantic period. Romantics wrote regarding the unique and the unusual, whereas in Realism, literature was compose ab go forth the average and ordinary. The town where the novel takes place is Starkfield, an average farming community. There is not much in the town that is of interest or anything libertine to be known for. In addition, literature from love affair focused on hopes, while Realistic literature illustrated skepticism and doubt. The narrator describes th e scene where Zeena declares to Ethan that her sickness is acquiring serious, saying, She continued to gaze at him through the twilight with a mien of wan authority, as of one consciously singled out for a great fate.Ive got complications, she express (108 Wharton). Hope for Zeenas health is nonexistent, and she, being a hypochondriac, confirms the fact that she feels doubtful about conduct. The Romantics wrote about the unusual and hopeful, which are characteristics that are not strongly represented in Realistic literature. The second aspect of Realism is the idea of Regionalism. One indication of Regionalism in literature is the characters barbarism. An excellent depiction of dialect is where Harmon Gow says, Wust kind, . . . Moren enough to kill close men (6).His regional accent is shown by the spelling and punctuation, allowing the reader to have an idea of how Harmon would have said it. Another aspect of Regionalism is the customs and the way of animation of the characters . One way of life that the characters are accustomed to is the normality of marriage between cousins. As this practice is not enthusiastically accepted everywhere, it brings the Regionalistic aspect to the novel. Regionalism, which includes the characteristics of dialect and customs, is a critical component of Realism.Third, Realistic literature uses the concept of Naturalism. In Ethan Frome, the bleak spend setting is a primary clue that nature plays a key role in the story. Nature is displayed as a powerful and malevolent force that is indifferent to humankind. In the novel, the narrator once stated, But when winter shut down on Starkfield, and the village lay under a sheet of snow perpetually renewed from the pale skies, I began to see what life thereor rather its negationmust have been . . . (7). This statement depicts the winter seasons in Starkfield as gloomy and undesirable weather.Aside from the setting, the basic animal nature of humans also draws out the Naturalistic tra its in Realism. The narrator tells what was going through Ethans mind following the smash-up, . . . and far off, up the hill, he heard the sorrel whinny, and thought I ought to be getting him his feed. . . (172). At such an intense moment, Ethans animal nature brings him to think about tending to his hungry horse instead of caring about his and Matties teetering lives. These examples indicate the sense of nature and its forces used in the literature of Realists.Edith Whartons novel, Ethan Frome, is a wonderful example of Realistic literature. Its style shows signs of a distinct shift away from Romanticism and illustrates the aspects of Regionalism and Naturalism, two major components of Realism. Authors of the Realistic period depicted life as typical, everyday people lived and knew it to be, using these important points. The ordinary characters that dealt with common problems and situations in the literature brought a new group of readers, establishing a unique new era that has changed the way people perceive life forever.

Patchwork EssayThe relationship between the object and the intervening spaces is non formal it is always rooted in the linguistic context of a particular setting Dalibor Vesely (in Brooker and Stone, 2007, p. 57).The Neues or revolutionary M practice sessionum (see figure 1) was completely reinforced in 1855. The building was design by a Prussian architect, Karl Friedrich Schinkel. The suggest of the building was originally built as an extension house to accommodate Altes Museum. Most of Karl Friedrich Schinkels works were Neo-Classical, such as, Neue Wache also known as New Gate House and The Konzerthaus Berlin (von Buttlar, A. Architectural Guide 2012, pg 4). Architecture in style of Neo-Classic contains the component of characteristic temple-like features of Greek and Rome (for instance, Acropolis in Athens and The Pantheon inRome) Architecture, rolls of long-shanked columns, pediments and domed detonator, for example (see figure 2). One of the most important elements in Greek and Roman architecture was balance and symmetry (see figure 3) which was hugely potent in the structure of neo-classical. Many neo-classical architecture have one component that can be identified as its style, the use of columns, that are normally built to almost the same height as the building.Columns are used to secure the symmetrical and balance of the dimension of the building as it is the efficaciousand evident use of method as for exterior. Also, the uses of columns support the pediment. The arch and columns, however, have comparatively become a symbol of Greek and Romans architectural style. Some believes those features are a discernible and crucial part in the revival of its style. Thus it remains a staple of neoclassical architecture, together with its distinctive domed roof (N/A. (2012) NeoClassic, Online, Avalible at http//www.neoclassic.com) . Neues Museum built in a Neo Classical style that began in the 19th century, the building spanned over three floors incl uding a grand staircase. The design of the Neues is to a great extent influenced by Stoa in Athens classical Greek architecture. Inside this building is a broad staircase and iconic columns, which lead towards a bronze hepatic portal vein that then leads to a double staircase to the ending upper floor which was nearly destroyed during the Second World War. In 2003, British architect David Chipperfield, whose acquire was to restore the parts of the build that were destroyed while also keeping conservation requirements.He wanted to keep to the original structure while creating doggedness with the existing structure. The reinvigoratedly designed expedition rooms were built mainly of pre fabricated concrete elements, which consist of Saxonian marble chips. In the Northwest wing of the new build it was constructed by recycled handmade bricks. David Chipperfield has managed to not only keep the original quality of the build but almost enhance its structure without losing any of the builds feature. (Minner , Kelly . Neues Museum / David Chipperfield Architects in collaboration with Julian Harrap 28 Apr 2011. ArchDaily. http//www.archdaily.com/127936) In conclusion, after the research through this essay, we strongly agree with the quote The relationship between the object and the intervening spaces is not formal it is always rooted in the context of a particular setting. Hence the Neues Museum is situated on an island which surrounded by other neo-classical architecture, heretofore though the building was built after the neo-classical trend had become unfashionable. Thus that makes the Neues Museum blends in with its environment.Bibliographyvon Buttlar , Adrian. Neues Museum Berlin.

Depression: Neurobiological and Neuropsychological Models

Depression neurobiological and Neuropsychological ModelsA correlation of Neurobiological and Neuropsychological cognitive specimen toward DepressionAbstractDepression is a chronic illness that has stirred centuries of debate regarding its mechanism. Notwithstanding the sharp contrast among theories that develop been proposed to explain the underlying source of printing from unlike perspectives, all of them accept the fact that it asks body, mood and even thoughts of individuals and as World Health organization predicted, it is evaluate to be the second rational turnover by 2020. The most(prenominal) compelling standards regarding the source of depression and its treatment in this realm atomic number 18 Monoamine seat and cognitive model. Monoamine model claims that depression has a biological source and it is apparent movementd by neurochemical substance imbalance in individuals, whereas ungenerous on cognitive model impaired information treat and cast let on biases are the key factors in the development of depression. The present paper attempts to assert the missing point in each(prenominal) of these theories and propose an explanation more or less the mechanism and treatment from devil similar perspectives Cognitive Neurobiological and Cognitive Neuropsychological, which work as a combination of Monoamine and Cognitive model. Both of these models categorize biases fanny on two passageways Bottom- Up and Top- Down touch. With the help of cognitive Neuropsychological model, it is shown how veto affective souring clear be the main core of depression, man Neurobiological model allow for show how hyper activation and hypo activation in different brain regions can develop depression. Therefore, a correlation of both models can explain underlying source of depression and thus can be used for modifying depression symptoms.DefinitionDepression is a universal mental disorder that has been growing at an alarming rate. It give be the second mental disorder by 2020 most people will be affected by depression in their lives either directly or indirectly, through a friend or family member. It is a severe and even painful disorder that will influence almost all aspects of sufferers life. Most people misdiagnose depression as feeling down, but depression is not a sign of weakness and is not the same as passing blue mood. According to UK medical reference, depression will be identified and categorized base on its symptoms, which is called ICD10 clinical criteria of depression and depends on the number of symptoms, types of depression, can be diagnosed. Symptoms arePersistent bittersweetness or low moodLoss of interests or pleasureFatigue or low energyDisturbed sleepPoor concentration or indecisivenessLow self-confidencePoor or increased appetiteSuicidal thoughts or actsAgitation or slowing of movementsGuilt or self-blameIf an individual suffer from 4 of these symptoms most of the time for at least 2 weeks, he/she will be di agnosed with mild depression, and with 5 to 6 of symptoms he/she suffer from moderate depression and in dangerous cases or severe depression, depressed person has more than 6 symptoms.Models of depressionA significant number of studies have been trying to reveal the mechanism of depression from different perspectives. Among the biologically base theories, the most reliable model that arguing reasonably about underlying source of depression and proposing acceptable treatment is Monoamine model. Monoamines are neurotransmitters and neuromodulators that ac sockledge serotonin, dopamine, norepinephrine, and epinephrine. The basic concept is that neurotransmitter imbalance within the brain is the main core of depression and neurotransmitters can be balanced again by using antidepressant medication. Type of antidepressant medication depends on severity of symptoms for patients suffering from dysphoria (low mood) SSRIs or norepinephrine reuptake inhibitors can be used, objet dart anhed onia patients (ones with the loss of energy and pastime of life) should be treated with norepinephrine and dopamine enhancing drugs (SNRIs). Despite their immediate effects at the synaptic level, in approximately 40% of the cases, they are ineffective in the short time and 30% of patients will suffer from depression within 12 months after recovery. This outcome apprizes that depression is not only the cause of chemical imbalance and psychological factors play an important role in its development. On the other hand, the most prominent and empirically based model of psychological factors of depression is cognitive model proposed by Aaron Beck in 1976. This model claims that blackball affective biases, which are blackball biases in perception, attention, emotional processing, thoughts and rumination and even memory, will affect individuals information processing and lack of cognitive control over these negative biases are the main cores of depression. According to this model, depr essed people are credibly to experience different phenomena such as negative cognitive triad, think negatively about themselves, their future and even the world unconditional blockade, engine block unequivocal information, inhibitory deficits, inability to disengage from negative stimuli. The model defined depression like an infinite loop, which receive feedback from its componentsFigure 1 cognitive model of depressionBeck claimed that by the help of cognitive behavioral therapy (CBT) and behavioral activation therapy (BA) negative biases and negative schemata of depressed people can be modified, however the existence was far from his thought and CBT and BA failed to cure depression, therefore scientists try to find a better explanation and treatment. Based on Becks cognitive model, two models have been proposed by researchers Cognitive Neurobiological and Cognitive Neuropsychological model, which are built on the assumption that negative stooge-up and top-down biases are zip py in development of depression.Cognitive neuropsychological modelThis model was proposed in 2011 and is a combination of Monoamine model and Cognitive model. From neuropsychological perspective environmental factors, inheritable factors and personality can change the function of monoamine neurotransmitters this neurotransmitter imbalance causes negative affective processing biases, which is the impairment of information processing peculiarly in emotional and reenforcement processing and play the main role in development and treatment of depression and finally the negative affective processing will cause negative schemata in depressed people. In comparison to healthy individuals, who process information in positive way, in depressed people the negative affective processing will change this automatic process more negatively.The difference between Neuropsychological model and cognitive model is in the formation of negative schemata based on cognitive model negative schemata are a result of early hostile life experience and they influencing the information processing, while cognitive psychological model claims that negative schemata are not the direct result of life experience, instead they are caused by negative information processing biases. Neuropsychological model categorized negative biases proposed by cognitive model into two groups Bottom- up biases and Top-down biases.Bottom-up biasesNegative biases that give rise to formation of negative schemata are called bottom-up biases and consist of perceptual biases especially negative emotional perception, negative thoughts and rumination and reward- punishment processing biases. Generally, healthy individual discriminate positive information or less negative information from environment, while depression makes sufferers to perceive more negative information from a stimulus faster and filter out the positive information. In a study done by Persad and Polivy in 1993, they observed individuals with depression have difficulty when they were shown facial emotion paucity in identification, perception and even sensation of facial emotion was common in these patients. A series of experiments were conducted as a support for this finding and in around all of them biases toward negative part of stimuli is reported. For example in another study, researchers found a cut back sensitivity toward happy faces, but an extreme sensitivity to sad faces. There is also neuroimaging evidence that support their result. There is a known pathway in perceiving information, which consists of Thalamus (responsible for the distribution of afferent signals), the Dorsal Anterior Cingulate pallium (region that relays top-down cognitive control from the Dorsolateral anterior Cortex) and the Subgenual Cingulate Cortex (a region that integrates emotional feedback from the limbic system and projects to higher-order cognitive structures). Information from environment will pass through this pathway from Thalamus to Amyg dala, which is responsible for detecting emotion and finally with the help of Dorsolateral prefrontal Cortex Amygdala bodily function will be controlled in order to not to perceive only negative information. Depressed individuals seem to have a longer and more intense Thalamus and Amygdala exercise as a response to negative stimuli. They also showed greater activity in Subgenual Cingulate Cortex, which is a region connecting limbic activity to higher cortical level (Prefrontal Cortex), whereas regions that are responsible for cognitive control, Dorsolateral Prefrontal Cortex and Anterior Cingulate Cortex, showed a reduction in perceptional processing, which means less cognitive control over Amygdala and Thalamus, therefore more negative stimuli will be perceived.Figure 2 negative perceptional biasesHow we perceive emotion will determine how we think about our environmental events and ourselves. As currently said, depression will induce perception and as a result will alter individ uals thoughts in a negative way. Since Individuals are more likely to discern negative information, it is highly probable that their life events, especially ones that are related to their ill luck, determine their perspective toward themselves they suffer from lack of self-steem, since they think they are useless, which step by step will cause more negative perception and more negative thoughts. This situation is like an infinite loop and is called rumination. Different brain regions involve in this process, which again prove lack of cognitive control in depression. As previously discussed, hyperactivity in the Amygdala and Hippocampus increase activity of Subgenual Cingulate Cortex (SCC), which is a connection between lower structural and cognitive part of brain and higher ones, therefore, Medial Prefrontal cortex (MPFC), a specific region that is in charge for internal representation of self, will be activated as a response negative information that is received from SCC. Beside t he hyperactivation in these parts, there is hypoactivation in higher levels, especially in Dorsolateral Prefrontal Cortex and Ventrolateral Prefrontal Cortex, cognitive control regions this reduction causes less control over Amygdala and Hippocampus and result in more negative perceptuational biases.Figure 3 negative thoughts and ruminationAfter this finding researchers went further and tried to determine how depression affects the reward and punishment process. Interestingly they indicate an exaggeration in negative performance feedback, while a reduction in reward seeking behavior. Neuroimaging evidence revealed an increased activity in the Amygdala as a response to negative situation and decrease activation in the Amygdala, Striatal regions, prefrontal cortex, Nuscleus Accumbens and Dorsal Anterior Cingulate Cortex as a response to reward. This evidence supports the claim that was made earlier with respect to impairment cognitive control in depressed individuals.Top-down biasesTh ese types of biases are negative biases that bolster the existence of depressive state and are composed of emotional attention and emotional memory. Not all the information we perceive from environment will be processed only those that are checked will be selected for further processing. This selecting process in healthy individual is more in favor of positive stimuli, which means greater Rostral Anterior Cingulate Cortex (ACC) activity when they successfully inhibit attention to positive stimuli, while in depressed individual this area cannot be activated in response to positive stimuli and are unable them to disengage their attention from negative stimuli. Disengagement attention requires a top-down mediation from upper-level cortical regions, which in depression these regions cannot work properly. Moreover, depressed individuals suffer from lack of selecting and guiding their attention toward positive information and as a result they attend to more negative stimuli. Neuroimagin g studies reveled 4 brain regions that are responsible for the whole process of attention Ventrolateral Prefrontal Cortex (VLPFC associated with control over stimulus selection), Dorsolateral Prefrontal Cortex (DLPFC) and Anterior Cingulate Cortex (ACC associated with disengagement functioning), Superior Parietal Cortex (SPC associated with shifts in gaze). Depression will affect the activity in these regions Prefrontal Cortex, especially Perigenual ACC, including Brodmann areas 24, 25, and 32, which will cause negative attentional biases reduced activity in the right VLPFC, therefore they are less likely to guide their attention toward positive stimuli decreased activity in right DLPFC and right SPC, which cause an impaired disengagement from negative stimuli greater activation in ACC when successfully inhibiting attention to negative stimuli and less activity as a response to positive stimuli.Figure 4 negative attentional biasesVarious researchers claimed that depressed individual s prefer to remember their failure or negative events rather than their success. Their argument is base on the result of differnet tasks in which depressed individuals showed biases in remembering negative stimulus, not for positive materials. They extract that since these patients are highly probable to perceive and attend negatively, they are more likely to encoding and recalling negative information. Thanks to neuroimaging studies, their claim was proved. As we might know hippocampus is an essential region for episodic memory and is connected to amygdala and as already discussed Amygdalas activity is increased toward negative stimuli, which corpus to increase activity in Hippocampus as well as Caudate and Putamen, regions for implicit memory and skill learning, in negative situation and as result will bolster the recall probability of negative information. Figure 5 negative memory biasesAccording to cognitive model, negative schemata are the most responsible source for developi ng depression. Base on Neurobiological model, there is a circuit that involve in forming belief and representation of individuals life, environment and even themselves. The elements of this circuit are Medial Prefrontal Cortex that is a higher cortical level responsible for internal representation, Anterior Cingulate Cortex that is an intermediate level and a connector between limbic area and Prefrontal Cortex, and finally Amygdala, a lower structural level which detect and process emotion. The high activation in this circuit will cause the maintenance of depression state.Individuals at luck of depressionAccording to cognitive neuropsychological model, we can predict the take chances factors of depression and we might be able to prevent its development. The most important factors are neuroticism, genetic factors and recovered depressed individuals. Neuroticism, which is a personality trait, characterized by anxiety, moodiness, worry, envy and jealousy, is most well-established risk factors for depression in non depressed people, however negative attentional biases are not found in them and it suggest that they only suffer form a bottom-up biases. Fortunately since they do not have the top down biases, their biases might be diminished by help of antidepressant drugs that influence bottom-up biases directly. As well as neurotic individuals, relative of depressed individual are in high risk of depression, since they tend to score higher on measures of neuroticism. Moreover, they show a greater activity in Amygdala as well as a reduced Ventral Striatal responsiveness to reward and less efficient activation of Parietal and Temporal networks during working memory performance. All together prove the existence of risk of depression in these individuals. Last vulnerable individuals are those who recently recovered from depression. They have behavioral biases toward negative stimuli as well as abnormal activity in Amygdala. All of these vulnerable individuals exhibit b ottom-up biases that are similar to depressed people.ConclusionNeuropsychological model and neurobiological model are proposed base on cognitive model and believe that different biases will cause and help the depression state in both depressed people and individuals at risk of depression. According to them, depression is a sequential process that is caused by two pathways Bottom-up and Top-down biases. Bottom-up biases will influence the lower cognitive and structural level of brain and is the main cause of generating depression, while Top- down affect the higher level and is responsible for maintaining the depressed state. By help of antidepressed drugs, the bottom up biases (perceptional, toghts biases) of depression will be modified and by help of CBT and BT, the top down biases ( attentional and memory biases) will be remit in stages . Figures below are used to show development of depression base on two models.Figure 6 cognitive neurobiological modelIn this figure the whole pro cess of depression is shown as a loop and as can be seen each step will get feedback to each other, even depressive symptoms will influence the Schema activation, which make the whole system stronger. The blue boxes are brain regions that are described as bottom-up biases, while gray boxes are more higher structural levels or top-down biases, which are responsible for cognitive control.Figure 7 cognitive neuropsychological modelAs can be seen the environment event or genetic factors or personality will cause an imbalance in monoamine transmitters, this change cause negative affective biases (perceptual biases), bottom-up biases and lack of cognitive control over these biases, which is a result of environmental trigger as well as bottom-up biases will increase the chance of depression by generating dysfunctional negative schemata dysfunctional negative schemata will causes more severe and higher level of biases (top-down biases). discolour boxes are treatments that can be use for ea ch step.

Characteristics and Advantages of Database Approach

Characteristics and Advantages of infobase ApproachDatabase Design ConceptsNitya MandalIntroductionThe over both assignment deals with characteristics of entropybase strategy, its approach and how it replaced the register based approach.In every plaque there is engage of informationbase. Database is parade of selective information in a grammatical constructiond and more musical arrangementatic way that helps in retrieving the information easily and efficiently. Before database transcription came in to picture there was file based approach in which there were application programs which were used to perform services for end exploiter and throw explanations. However every program used to manage its own data. Due to this and various other limitations file arrangement was replaced by database corpse.The modern database approach has a lot advantage that helps not only the organization but also the common people in their day today life.In the below assignment on the who le the characteristics of database has been described.Task 1 Describe the main characteristics of the database approach and contrast it with the file-based approach. Analyze the key issues and application of databases within organizational environments.Main Characteristics of the Database ApproachSelf-describing nature of a database system A DBMS catalog stores the description of the database. The description is called meta-data which is data about data. This supplys the DBMS software to work with different databases.Insulation between programs and data Also known as program-data independence. Without making any swap to DBMS adit programs the data reposition structures and operations can be adjustmentd.Data abstractedness The availability of data model approach helps in hiding the natural view of data i.e. the storage details and other internal level entropy and provides the conceptual view of database.Support of multiple views of the data The database approach allows each exploiter to defend their own view of the database which describes only the data of interest to that user. thither are various benefits of having multiple views such asReduce complexityProvide a level of securityProvide a mechanism to customize the appearance of the databasePresent a consistent, unchanging picture of the structure of the database, even if the underlying database is changedSharing of data and multi-user transaction touch The database approach allows a countersink of concurrent users to retrieve and to update the database. Spreadsheets cannot offer several users the ability to view and work on the different data in the same file, because once the scratch user opens the file it is locked to other users. Other users can read the file, but whitethorn not edit data. For example, when one user is changing data hence the database should not allow other users who query the same data to view the changed, unsaved data. Instead the user should only view the original data . tone downled plan of attack to database may includea security systeman integrity systema concurrency lock systema recovery check systema user- portalible catalog.File-based administrationFile-based systems were the manual based approached used for managing the files. Its mainly the collection of application programs that used to provide services for the end-users. Each program was defined for a circumstantial task and cant be used simultaneously with each other.However, there are many pitfalls of file based system.Separation and isolation of dataWhen data is isolated in sort files, it is more difficult for us to access data that should be available. The application programmer is required to synchronize the processing of two or more files to ensure the correct data is extracted.Duplication of dataWith the use of the decentralized file-based approach, the uncontrolled duplication of data used to travel by which can lead to loss of data integrity as well as is wasteful as it o ccupies unnecessary space in memory storage area.Data dependenceUsing file-based system, the physical structure and storage of the data files and records are defined in the application program code. This makes the file to be program-data subject. If the user want to make any change in the existing structure it was a difficult a task and will lead to a allowance of program. Such maintenance activities are time-consuming and subject to error.Incompatible file formatsThe structures of the file are dependent on the application programming language. However file structure provided in one programming language such as direct file, indexed-sequential file which is available in COBOL programming, may be different from the structure generated by other programming language such as C. The direct incompatibility makes them difficult to process jointly.Fixed queries / proliferation of application programsFile-based systems are very dependent upon the application programmer. Any required queries or reports have to be written by the application programmer. Normally, a fixed format query or report can only be entertained and no facility for ad-hoc queries if offered.Database ApproachIn order to overcome the limitations of the file-based approach, the concept of database and the Database Management System (DMS) was emerged in 60s.Advantages of DBMSsControl of data periphrasisData consistencyMore information from the same amount of dataSharing of data change data integrityImproved securityEnforcement of standardsEconomy of scaleBalance conflicting requirementsImproved data accessibility and responsivenessIncreased productivityImproved maintenance through data independenceIncreased concurrencyImproved backup and recovery servicesDifference between file system and DBMS 2Both systems contain a collection of data and a set of programs which access that data. A database counselling system coordinates both the physical and the logical access to the data, whereas a file-processing system coordinates only the physical access.A database management system reduces the amount of data duplication by ensuring that a physical piece of data is available to all programs authorized to have access to it, whereas data written by one program in a file-processing system may not be readable by some other program.A database management system is designed to allow flexible access to data (i.e., queries), whereas a file-processing system is designed to allow predetermined access to data (i.e., compiled programs).A database management system is designed to coordinate multiple users accessing the same data at the same time. A file-processing system is usually designed to allow one or more programs to access different data files at the same time. In a file-processing system, a file can be accessed by two programs concurrently only if both programs have read-only access to the file.Redundancy is control in DBMS, but not in file system.Unauthorized access is restricted in DBMS but n ot in file system.DBMS provide backup and recovery. When data is lost in file system then it not recover.DBMS provide multiple user interfaces. Data is isolated in file system.In file system there is no concept of tables orrelationsbetween tables it just organize the records row by row. Database system contains table and relationbetween the tables.A File manager is used to store all relationships in directories in File Systems where as a data base manager (administrator) stores the relationshipin form of geomorphological tables.Disadvantages of database approachThe Database approach too has some disadvantages. They areComplexityDatabase management system is an extremely complex piece of software. The users must be familiar with its functionality in-order to make full use of it. Therefore, training for the administrators, designers and users is required.SizeThe database management system consumes a inviolable amount of main memory as well as a large amount of disk space in order to make it clear efficiently.Cost of DBMSA multi-user database management system may be very expensive. Even after the installation, there is a high recurrent yearly maintenance cost on the software.Cost of conversionWhen moving from a file-base system to a database system, the company is required to have additional expenses on hardware acquisition and training cost.PerformanceAs the database approach is to manage many applications rather than exclusively for a particular one, some applications may not order as fast as before.Higher impact of a failureThe database approach increases the vulnerability of the system due to the centralization. As all users and applications reply on the database availability, the failure of any component can bring operations to a halt and affect the services to the customer seriously.Application of database in an organizationA management information system(MIS) is an integrated, user machine system for providing information to support operations, manage ment, analysis, and finale making functions in an organization. The system utilizes computer hardware and software, manual procedures, models for analysis, plan, control and decision making and a data base.Managers at all levels use similar data. Operating managers require data which is timely, precise, detailed, internal and historical. Upper level managers need data which is aggregated, external as well as internal, future oriented as well as historical and covering a longer duo time. An effective MIS cannot be built without viable data management tools.Any organization has management planning and control activities in the middle and strategic planning and policy making in top management. The database related to an organization contains data relating to the organization, its operations, its plan and its environment that helps in decision making. Transactions record actual results of organizational activities and environmental changes and update the database to maintain a curren t image.People in the organization query the database for information to conduct the daily operations. Middle management receives reports compare actual results to previously recorded plans and expectations. The corporate database provides data for modeling and forecasting which support top management needs. The corporate database supports all levels of an organization and is vital for operations, decision making and the management process.Network database This model stores the records with links to other records. Most network database include hierarchical model. This type of database can spread over the geographical area when used in large organization.Another database application is OLTP (Online Transaction Processing).Database applicants are any type of company that has customers/clients, keeps stocks of products, provides a service etc. pay institutions, accountants, estate agents, solicitors, training organizations, schools, colleges, motor dealers, opticians etc. Practicall y every category of business uses the database system.Database id used in Universities for student information, course details, and grades. It is used in Airlines for reservations and inscription information. Also in Credit card transactions database approach is used for purchase on credit cards and generations of monthly statements. Apart from this in military personnel resource database is used for information about employees, salaries, payroll taxes, benefits and for generations of paychecks. In Banking too database is used for customer information, accounts, and banking transactions.Task 2 The database management system (DBMS) has promising strength advantages. Critically evaluate the advantages and features of database management systems.Advantages 4There are various advantages of introducing database system approach in an application system. Some of them are discussed belowControl of data redundancyIn the database approach there is central repository of data that not only he lps in avoiding the wastage of storage space but also helps in controlling the redundancy by data integration. It helps in avoiding the duplication of data by following techniques like normalization and key concepts. Thus the data is stored in database table at only one place from where it can be retrieved when needed, by avoiding redundancy.Data consistencyThis is maintained by following the concept control of redundancy. If the data is stored at one place in a database then while updating any information the changes will be through at only one place which is reflected at all place where ever it is present in whole database. There is no need to change at all places where that data is present. For example if an employee has a change in his address then only in employee table the address will be changed. From there it will be updated every where in database. Thus it ensures all copies of the data are kept consistent. This helps in maintaining consistency of information throughout the system without any loss or misleading of information.More information from the same amount of dataWith the integration of the operated data in the database approach, it may be assertable to derive additional information for the same data. All data is stored in a single database, instead of being stored in various other separate files, making the process of obtaining information quicker and in an easy way. For example, in the file-based system of a property company, the Contracts Department does not know who owns a hired property. Similarly, the Sales Department has no knowledge of affiance details. Now when we combine these files, the Contracts Department has access to owner details and the Sales Department has access to lease details. Thus more information can be derived now from same available data.Sharing of dataThere is central repository of data in a database system that makes it available to the entire organization and can be shared by all authorized users.Improved data int egrity .5Data integrity mainly refers to ensuring that data is recorded exactly as intended and when retrieved its in the same way as it was when it was recorded. There should not be any data loss when data is retrieved. It mainly provides the validity and consistency of stored data. The database application has various Integrity Constraints, which are consistency rules that the database is not permitted to violate. One of the constraints is specifying data type for every data item. Another is referential integrity constraint in which a record in one file must be related to records in other files. These constraints help in maintaining integrity of data.Improved securityDatabase approach provides a protection of the data from the unauthorized users. It may grow the term of user names and passwords to identify user type and their access right in the operation including retrieval, insertion, updating and deletion. Providing the facility of accessible rights in database system for vari ous levels in an organization makes it secure for use. For example, the DBA has access to all the data in the database where as a branch manager may have access to all data that is related to only his branch office. In a similar way a sales assistant may have access to all data relating to properties but dont have any access to sensitive data such as staff salary details.Enforcement of standardsThe integration of the database enforces the necessary standards including data formats, naming conventions, documentation standards, update procedures and access rules. It helps in maintaining standards among the user in an organization. The sharing of data within departments, exchange of information among the users on various projects become easy following the standard database on a centralized environment.Economy of scaleUsing centralized database helps in combining all organizations operational data into one database with applications to work on one source of data. This helps in cost savi ng as well as reducing redundancy among the applications. The organizations can invest their money on buy new tools like good processors, storage space and communications devices. Instead of each department buying individually, the organization as whole can do this by saving operational and management time and money.Balance of conflicting requirementsBy having a structural design in the database, the conflicts between users or departments can be resolved. Decisions will be based on the base use of resources for the organization as a whole rather that for an individual entity.Improved data accessibility and responsivenessBy having integration in the database approach, data accessing can be crossed departmental boundaries. This feature provides more functionality and better services to the users.Increased productivityThe database approach provides all the low-level file-handling routines. The provision of these functions allows the programmer to concentrate more on the unique(predic ate) functionality required by the users. The fourth-generation environment provided by the database can simplify the database application development.Improved maintenanceDatabase approach provides a data independence. As a change of data structure in the database will be affect the application program, it simplifies database application maintenance.Increased concurrencyDatabase can manage concurrent data access effectively. It ensures no interference between users that would not result any loss of information nor loss of integrity.Multiple User InterfaceDBMS provides a variety of user interface like query language for casual users, programming language interface for application programmers, command codes for parametric users, menu-driven interface for standalone users. It provides web based graphical user interface interface to database.Improved backup and recovery servicesModern database management system provides facilities to minimize the amount of processing that can be lost fo llowing a failure by using the transaction approach.Referenceshttp//www.gitta.info/IntroToDBS/en/html/DBApproaChar_mehrfachn.htmlhttp//1upto.blogspot.sg/2012/09/list-four-significant-differences.html.http//databases.about.com/od/administration/a/choosing_a_db.htmDATABASE SYSTEMS- A Practical approach to design, implementation and management by Thomas Connolly and Carolyn Begg- 4rth Editionhttp//www.cvauni.edu.vn/imgupload_dinhkem/file/CSDL/Fundamentals_of_Database_Systems, _6th_Edition.pdfhttp//databases.about.com/od/administration/a/choosing_a_db.htm

Dopamines role in the Psychological Architecture of Pleasure and Rewar

Dopamines role in the psychological architecture of pleasure and reward indicates that it is a major element in the finish of reinforcement (Arias-Carrin & Pppel, 2007, p. 484). This role was postulated from the discovery of dopamine in reward pathways that are found originating from the midbrain (2). From these discoveries, it has been shown that dopamine has a profound allude upon the existence of reward-seeking behaviors (Arias-Carrin & Pppel, 2007, p. 481). A 2006 study done by Mathias Pessiglione and his colleagues demonstrated that subjects given L-DOPA, a precursor to dopamine, were more likely to remember decisions that light-emitting diode to rewards and continue to make those decisions (3). While the experiment central to this study was conducted in the form of a gambling game, the effects that dopamine has on decision fashioning and reinforcement heap be derived from the observed effects that L-DOPA had on the participants. This derivation can be made not only because L-DOPA is synthesized into dopamine once in the brain but also because gambling is an illuminative behavior in terms of how it represents general reward-seeking behaviors and decisions. As scar Arias-Carrin and Ernst Pppel ramble it, DA dopamine is the brains mean for reinforcing behavior (Arias-Carrin & Pppel, 2007, p. 486). Furthermore, it has also been shown through experimentation that the responsiveness of dopamine levels in the brain to rewarding experiences is characterized by a degree of neuronal plasticity (4). In this context, plasticity refers to the brains ability to alter its responses to experiences in accordance with how new or unique the experience is. This quality can help the brain to act as a sieve, filtering out experiences that are n... ...re rapid release of dopamine into the synapse (13). While these mechanisms are different, both essentially pass the same end result of euphoria, wakefulness, and increased motor activity. These symptoms mirror those of a pe rson with high levels of dopamine, as is seen in psychotic patients. Indeed, high doses of stimulants can as yet lead to psychotic states involving hallucinations. The contrasting effects of antipsychotics and stimulants on not only behavior but also cognition and physiological processes help to generate a greater understanding of the way that dopamine affects both the mind and the body. While the many nuances and subtleties of dopamine neurotransmission are not well understood, observation of the way that psychotropic drugs influence dopamines normal functioning can help to create stronger links between this neurotransmitter and human behavior.
