Schindlers Ark essays

Schindlers Ark essays Task - A study of the character of Oskar Schindler to show that despite major obstacles and difficulties in his quest for justice for the Jews, he finally achieved his goal, at great personal cost to his own life. The story of Oskar Schindler and his legacy began on April 28th 1908 in the Austrian city of Zwittau. In 1918, when Oskar was 10, his family moved to the Czechoslovak republic of Masaryk and Benei. He immediately became best friend with his neighbours children, who were Jews and their father was the local rabbi. His family was also one of the richest in the area and Oskar was often showered in items of luxury. In 1935 the Schindler family business was failing and Oskar's father Herr Hans Schindler left his wife and Oskar's mother Frau Louisa Schindler, and moved to his own apartment. Oskar detested this. He would go into cafes and make speeches on his fathers treachery to his mother, who in Oskars eyes did not deserve this treatment, as she was a good woman who had done nothing wrong. 1939, The beginning of World War 2, and Oskar joins the Nazi Party. The opportunities that the war brings are what may have attracted Oskar to join the Nazi party. Oskar Schindler quickly got on good terms with the local Gestapo chiefs and rejoiced here over life in the beginning of the 1940s. He was a womanizer and heavy drinker, but continually risked his life to save his Jewish workers from the Nazi Death camps such as Plasw and the now infamous Auschwitz is Poland. Schindler was recruited by the German Intelligence Agency to collect information about Poles and was highly esteemed for his efforts - a fact that was to play a decisive role later in the war for Schindler, when he needed all his contacts. Amon Goeth, who passed his mornings by using his high-powered, scoped rifle to shoot at children playing in the camp, often would use it as an incentive for them to work harder. For example, some young men hauling coal ...

The Changing Roles Of Women In The Mafia Essay Example | Topics and Well Written Essays - 3250 words

The Changing Roles Of Women In The Mafia - Essay Example The study will focus on analysing information from authorities that are known for their efforts and track-record in researching into the Sicilian Mafia and Organised crime groups. In doing this, the research will focus on contemporary research works and field works that have been done by conducting various primary studies and research work like interviews and other things meant to inquire into the way research is done into the Sicilian model of the mafia and its processes. The research will also seek to inquire into specialised sources and works of authors who have in-depth experience and knowledge in studying women and the Mafia. This will include an insight into numerous works by persons who have spent the most part of the past 20 years studying and researching into the works of the Mafia and their evolutions over the period at hand. This report makes a conclusion that women in the Mafia were traditionally seen as the bedrock for the keeping together and transmission of the amoral familial traits of organized crime families and clans in Sicily. However, the past 20 years has seen a lot of changes and modifications in the way things are done in the Mafia and in societies. This include the fact that the Mafioso is more interested in cashing in on the opportunity to make money through smuggling and owning businesses in order to participate in money laundering. This is opposed to the old system where the Mafia took part in violent activities and violent crimes and offences in order to raise money and remain rich.

Abandoned Friendship Essay Example | Topics and Well Written Essays - 500 words

Abandoned Friendship - Essay Example I told him to be strong and remain contented with what little you have. In essence I gave him the shoulder to sob upon. Then he told me the unfortunate mission behind our going to the mall. He told me we were there to steal a few things which were important for him at that stage of his life. I was shocked to hear that and could not believe how I could be a part of such an activity. I told him this was amazing and I could have never thought of doing anything like that. He told me to help him otherwise he would stop calling me as a friend. My morals did not allow me to do such a thing. He forced me by hand to go to the mall and help him steal some stuff for him. I shrugged off completely and quickly. I made my way to my place without even looking backwards. That was the day this friendship came to an end. I was utterly shocked by his aggressiveness and I cannot believe, to this day, how I could have befriended such a human

Explain the Influence of Management Style on the Nature of the Employment Relationship Essay Example for Free

Explain the Influence of Management Style on the Nature of the Employment Relationship Essay It always a great deal for management to perform effectively in an organization, it is because they are the ones that are always look into by the people within the company. With the policies and guidelines that they give for the employees in order for them to achieve their goal effectively is the main reflection on the management style they implement and want to follow in the company. That is why in order for a company to succeed, management is always one of the main key, because it provides a better deal on addressing the main issue of relationship as well as policies. What is important for the management is that, no matter what and how they provide their management style in an organization, it should have positive output for both its people and also the stakeholders. Or always find a way to â€Å"strike the balance† between the two, because if people in the organization will not be given the right attention, it will be hard for company to survive, since these people are called as the â€Å"front liners† and the reflection of these performance will surely be reflected on the service they provide for the customer. On the other hand for the stakeholders, they maybe people that do not want to know more about how people or staff deals with their work, but more focus on the stability of the company, or simply â€Å"bottom line†. But, in order to achieve this there should be leader that must stand in front which will lead all these into reality. They say that a good leader is a good coach as well as moderator; these people are some of the very few people that knows how to encourage and provide hope for people and convert them to be an asset in the company and instead of a threat. Because there are other managers who thinks of efficient and effective people as threat, threat because they can overthrown the manager, because some managers are not that highly motivated and do not want to challenge themselves, that is why most companies development or progress are hardly achieve by these â€Å"power tripping: managers who would not want to see potential leaders to be what they deserve they can be, and inte4ad they be given challenge, they are either being ignored or left behind. For most effective managers or leaders who really provide great influence in an organization, they see company as business, not finance. This is the problem with some appointed managers or managers that are just being assigned without really understanding the position well. Actually managers are not financial comptroller, where the latter works more on how to control expenses but look into prioritizing how to increase sales and revenues. Managers forget the fact that they must lead and not always focus on the financials, because if they focus on the financials they should not be manager anymore, instead they should be working in the accounting or finance department. Another is that, managers are in the company to provide action and not just lesson. They must also provide community action, an action that would really help the company to go to its greatest potential and always dwell on how to prioritizing the important activities that needs to be done. For being an action man or woman in the company, it is also easy to find respect from the organization, since there is always hard work shown, and all of these provides great influence and eventually will result to success in the employment relationship within the organization. (Heller, R, 2007, pars. 4 and 9). Employee relations and theoretical interpretation In employment relation to employment relation, there are different types of theory that is applied in an organization. These are: (1) Unitary Theory, (2) Pluralist Theory, System, (4) Marxist, (5) Feminist, (6) Comparative, and (7) Postmodernism. For unitary theory, it is the existence of a single policy or authority that is being practice within the organization. This type of management theory is known in the very early years, where leaders form their own rule in the basis of what they think is right and people are mostly not given the rights to contradict or over rule the policy or guideline that was implemented. Classical Pluralism, is however is considered as the form of management is greatly influence by an electorate political group or any group that holds power over the society. Their main power is strengthen by the ideology that come from the community or societal group and this form of management style is well supported since it is perceived as for the good of many and not just from the group. System theory focuses is focusing on the inter-disciplinary representation of field science, which is complex nature of science, nature and science are the main basic on this theory. This also means that in every decision there is always a scientific explanation which needs to be followed or adhered. For Marxist theory, its philosophy mainly focuses on the diverse theory that Karl Marx which is mainly in the light of communism, this theory mainly involves such diverse fields like, aesthetics, ethics, ontology, epistemology and the philosophy of science as well. This is made popularize in the early strict and communistic era in Russia. On the theory about Feminism, it also provides a wide variety of discipline which mainly focuses on the common ideology of women’s role in politics, and these include: anthropology, sociology, economics, women as well as gender studies. This form of management looks after on the main concern of the greater women in the community which can be effectively being applied in the form of management within the organization. Lastly, for the theory about Postmodernism, which only shows that most of the people here are great fun of opportunities, like on and off the job training, like in the case of a project that will be eventually be started since the government has allocated some ideas in the organization. These theories have provided different impact in the organization since every theory is applied appropriately in the companies. It also provides a clear guideline as to how people can be managed effectively. Like take for instance a company that lies on the service that they provide, for example a company of systems development, which has given the authority to let users to participate in forming and firming the management standards and practices that the company must used. For the last two theories for management practices, comparative and post-modernism, for the first theory, Cooperative theory, this form of management, shows big importance to the greater majority of the people and these is brought out by the well collaborative effort shown from the employee and the management as well. This also shows that management must play big attention in their respective stores in a typical â€Å"look and feel† of the organization. (Hollinshead, Nicholls, and Tailby, 2003, pp. 9-41). The Importance of Collective Bargaining in an Organization For some companies accepting the presence of a Union is not that well accepted, because for some management it is just a source of employees of pushing other request that might even defeat the main vision or mission of the company. In fact the main objective of it is to provide a better deal of the needs of the staffs and not just raising some wants, which may lead to negative result. Companies or staffs must not always look into having an agreement that focuses not only for employee compensation or benefits but it should also focus on some other concerns like safety and help provision. This is because most industry, most especially manufacturing companies, automatically has a union and it provides a clear directive on what the policy that must be followed and this process must be strictly be send and follow up users. Collective bargaining has it own process which helps the management and the employees union to follow for better understanding of its agreement. In Ireland, this process is formed in a way that corresponds also to the company guidelines which is important to have it more appreciative and well respected by the stakeholder. (How Has Collective Bargaining Happen in Ireland, 2007).

Gold Strike, Relating To Cry, :: essays research papers

â€Å"Gold mining union plans one-day Free State strike† An article dated March 17, 2000   Ã‚  Ã‚  Ã‚  Ã‚  NUM, or South Africa’s National Union of Mineworkers, is organizing a one-day strike at Free State gold mines. They are protesting the poverty and job losses from the mines. NUM is the country’s biggest mining union with 50,000 members, and on March 22 the strike would affect five gold companies; AngloGold Ltd., Gold Fields Ltd., Harmony Gold Co., Avgold and African Rainbow Minerals. NUM spokesman Ikaneng Matlala didn’t say, however, how many members of the union would participate on the strike, but did say â€Å"All the gold mines in the Free State gold fields are going to embark on a strike.† The protest is against the gold mines because of the huge job losses in the last fifteen years. In 1987, gold, being the backbone of the economy, employed 530,000 miners. After the end of apartheid in 1994, South Africa’s economy was open to foreign competition, and the gold industry had to be restructured. The gold price has been decreasing as well, and today only 200,000 miners are employed. This current event relates to Alan Paton’s, Cry, the Beloved Country, because mining supported Johannesburg, and references were made to the mining industry throughout the book. Many characters voiced their opinion that it was the black men that economically supported the white men in South Africa, and they were diseased and injured by it. That they worked for cheap, were exposed to dangers, and then when they needed medical attention the non-European hospitals were less than inadequate. John Kumalo gave speeches on strikes against the gold mines. Gold was found in a new area, Odenaalrust, and the white men wanted to change the name because it was too hard to pronounce.

Prisons and Jails Essay

Almost all nations and cultures have made laws to protect their citizens. From the early years and over the decades these laws have been kept in force to prevent the societies from experiencing situations of anarchy. Different punishment has been provided for in different countries to prevent its people from adopting a path and practice of criminal activities. The world of today is characterized by the presence of criminals who are brought to book and punished in a variety of ways depending on the culture and values of any country or society. Prisoners have been locked up in prisons and meted out with terms that include punishment by way of a rigorous regimen of hard labor while undergoing the term as also milder ones that may include a stint in reformatory homes. Historically punishments have ranged from corporal punishment to death penalty, Several countries have for long been awarding the death penalty for committing heinous crimes that were executed in several forms that included, hanging, guillotine, by firing squad, lynching and now electric chair. The Babylonian Code of Hammurabi is the oldest record available to ascertain that a egal system existed to award punishment in the Middle East. Western countries were influenced by and followed the laws enacted in ancient Rome whereby each city had a court that worked under the Law of Twelve Tables so as to protect citizens and to make the rulers and governments effective. The Justinian Code is considered to be the most logical and effective legal system that was most effective in ancient times whereby punishment was meted out by the process of Law. In due course people began to realize the value of a legal system that protected citizens and each country began to appoint heriffs to deal with punishments and the justice system became a major part of society although they were never fool proof and were always characterized by shortcomings that put a question mark on the efficiency of the judiciary. In ancient times the justice and reform system was often misused when criminals were hung on crosses, sometimes tortured to death or placed in dungeons to die. Those citizens who protested were also treated as criminals and tortured or put behind bars. It was during this time, in the 19th century and mainly in the Roman Empire that civil justice was effectively implemented nd more prisons were built to punish criminals humanely. This soon had effect on the rest of the world and with the emergence of the modern world more prisons were built and departments set up to manage them effectively. With the widespread maturing of the legal system over the decades, more and more criminals were brought to book and the law abiding citizens heaved a sigh of relief especially during the time of the Queen of Britain at the turn of the 19th century. Under the new system the criminal was given an opportunity to prove himself innocent and the overnment had to prove a person to be guilty of crime within the prevailing provisions of law, before he could be sentenced to a term of punishment and imprisonment. Although capital punishment continued to prevail but it was awarded in the rarest of rare cases. Over the years with the influence of Human Rights Organizations and Civil Rights Movements, the trend has set in to rather reform the wrong doers than to award extreme penalties by giving sentenced criminals opportunities to amend themselves and to come back within the mainstream of society. Under the system convicts are put on probation or parole under the watchful eyes of probation officers appointed by courts to ensure that such people remain disciplined and strictly follow the code of conduct as outlined by the court. The view of punishment taken by society has changed dramatically over the years. Initially punishment comprised of physical torture, maiming, death by burning, hard labor, deprivation of food adequate clothing and shelter, but attitudes of the society have changed now and the belief is to punish by way of imprisonment of varying periods epending on the severity of the crime. Imprisonment today is considered punishment for one’s wrong doings, which is also consistent with the society’s objective of keeping such people aloof until they are reformed to lead a normal life within society. To insist that a person is sent to prison so that he is punished is wrong in today’s context since after he completes his term he has the justification to return to his old ways. Hence prison authorities today have a duty to fulfill by way of reforming the convict during his term so as to transform him into a more responsible citizen. It is for this reason that in most countries modern society is characterized by a prison and punishment system that strongly believes that the most effective form of punishment is to deprive the convict of his freedom until he is reformed. In this context the composition and diversity of prison population in America has been examined and found that presently over two million people are in American prisons. This does indicate that modern society has now been characterized by a pattern, which clearly indicates that the government is duty bound to ensure freedom to criminals once their 4 rison terms are over and that they gel back into society with a tag of respect and positive aspirations. The changing attitudes and trends have seen a constant inflow of inmates in the Federal, State and local prisons. The Federal government held a majority of 63% of the inmates while local municipal and county jails held 30%, and the remaining being accounted for in other prisons.. Most states have been experiencing a 5% increase in the number of inmates over the last three years. Private prisons held about 86626 prisoners which accounts for about 7% of the inmates in American prison. A private prison is a place in which convicts are physically detained by a private organization for profit at the instance of the legal authorities. These companies enter into an agreement with the federal government to take care of and reform and motivate prisoners and claim from them a fixed fee amount per prisoner. There are about 264 private prisons/correctional facilities in the United States that take care of about 110000 offenders. The concept of private prisons was floated to reduce government expenses in the long run, but the scheme has not worked effectively due to private sector neffectiveness with convicts, and having realized this the federal government is not encouraging further addition to their numbers. The number of private prisons is now set to decline gradually. Rates of imprisonment have greatly increased due to increase in the rate of criminal offences, which is considered a consequence of the fast track development that is taking place in the modern world. More delinquencies resulting from human inadequacies to tolerate inequalities have resulted in people taking the course first towards minor crimes and then graduating to bigger ones and then ultimately falling into legal traps that lead to their conviction and further imprisonment. In America imprisonment is the most common sentence in legislation for serious offences in terms of dealing with criminal activities, which explains the high number of prisoners in jails. Only effective and well targeted correction measures and programs can reduce criminal offending and over time there is good reason to target investment in preventive approaches for the betterment of those undergoing prison sentences. As discussed earlier, in the modern world the biggest punishment for a criminal is to urtail his freedom for the duration of his sentence and during this time it is the duty of the jail administration to make him undergo a rigorous regimen of correction and transformation into a more responsible and law abiding citizen. The American government has an arrangement in place whereby all jail administrators are to undergo a training program to specialize in dealing with and reforming convicts and to encourage them in displaying their creativity and interests so that when their prison term is over they can lead the life style that is in keeping with that of a responsible and respectable citizen. The American judicial and correction system is such that it is considered to be one of the most liberal in terms of providing guarantees of human rights and opportunities for misguided people to reform themselves. There are several government sponsored programs that provide for opportunities for such people to reestablish themselves for a better means of livelihood. The punishment part for their wrong doings gets over the moment they finish with the duration of their prison sentence and after that they can look forward to a happier life free of the stigma that attaches to a person of such background.

Solventless Claisen-Schmidt Condensation of Benzaldehydes

Backgrounds and Theory (A)Introduction of aldol condensation In an aldol condensation reaction, the ? -carbon of an aldehyde or ketone molecule reacts with another carbonyl carbon to form a ? -hydroxyl aldehyde or ? -hydroxyl ketone, followed by dehydration to give a conjugated enone if an ? -H is present. It is a very useful reaction for the synthesis of ? ,? -unsaturated carbonyl compounds. The aldehyde or ketone molecule is first converted to enol or enolate by acid or base catalyst respectively. In this experiment, the base-catalyzed method is used and the ? proton of the aldehyde or ketone molecule is removed by a strong base like hydroxides and alkoxides to form an enolate ion: Although hydroxide ion is not strong enough to convert all of the aldehyde or keton molecules to the corresponding enolates for both aldehydes and ketones (i. e. the equilibrium lies well to the left), there are usually enough enolate ions for the reaction to proceed at a reasonable rate. The enolate ion will then react with the carbonyl compound to form an intermediate anion, which is quickly protonated by water. When the ? hydroxyl aldehyde or ? -hydroxyl ketone is formed, it will be sometimes spontaneously dehydrated to give an ? ,? -unsaturated carbonyl compound since a C=C bond can be formed by this process and it is very stable due to the conjugation with the carbonyl group. Therefore if the dehydration is not spontaneous, it can also be easily induced by gentle heating. However, self condensation will occur, especially if both of the reactants are ketones, and a mixture of products will be formed. This is mainly due to the similar electrophilicity of the reactants.For example, when 3-pentanone is reacted with cyclopentanone: A mixture of products will be formed as both the reactants can become enolate ion and react with itself or another reactant. Also, more kinds of products will be formed after dehydration as different kinds of ? -proton is available. If the reactants are unsymmetrical, the reaction will become more regioselective. For example, if 2-methylpentan-3-one is reacted with reacted with cyclopentanone: The upper one will be the major product since ? -proton is available for the formation of conjugated double bond by dehydration.The extra stability of the product shifts the equilibrium to its side. (B)Claisen-Schmidt Condensation – a Branch of Aldol Condensation Clasisen-Schmidt condensation is a branch of aldol condensation which eliminates most of the regioselectivity problems. In the reaction, an aromatic aldehyde is condensed with a ketone to form an ? ,? -unsaturated ketone. For example: Since an extra alkyl group (EDG) is present in ketone, it is less electrophilic than the aldehyde. Therefore only the ? -carbon of the ketone will attack the aldehyde, but not the other way round.Also, there will not be any self condensation as only aldehyde will be attacked. The dehydration process of the above reaction is also regioselective as there is only one kind of ? -proton present in the compound. Therefore only one kind of product will be formed. In this experiment, the Clasisen-Schmidt condensation of benzaldehyde and p-methylacetophenone will be studied. (C)Traditional Method vs Solventless Method (Green Chemistry) Organic reactions usually require organic solvents as to provide a medium for the interactions of reactants and to moderate the temperature and reaction rate.Nevertheless, the use of organic solvent needs a significant cost on materials required and also increases the burden to chemical waste treatment and the environment. Green Chemistry is therefore developed in order to reduce material consumption and increase the efficiency of chemical production by minimizing the use of solvents. The Claisen-Schmidt condensation of benzaldehyde and acetophenone would have a very high atom economy (> 92%) with the reaction solvent eliminated. In this experiment, the efficiencies of the traditional and solventless methods will be compared.

The Media and Terrorism

The Media and Terrorism The question of relations between the media and terrorism is rather controversial because of the phenomena’s interdependence. It is possible to state that the power of terrorism can be enhanced by the media because the media resources are used as the tools for terroristic organizations, but the media cannot cause terrorism directly.Advertising We will write a custom essay sample on The Media and Terrorism specifically for you for only $16.05 $11/page Learn More Terroristic organizations are inclined to use the media in order to realize the definite purposes and complete the organization’s goals, but the activities of the free media cannot provoke the development of terrorism without references to terroristic organizations (Terrorism and the media, 2008). The media can stimulate the power of terrorism because the principle of freedom followed by the media resources depends on spreading any type of information, and terrorist organizations rely on spreading their messages in order to affect the public and cause the people’s fear (Camphuijsen Vissers, 2010). As a result, the impact of terroristic organizations and their activities increase, however, the media in their nature cannot cause terrorism because of the differences in goals and purposes. The purposes and goals of terroristic organizations are to scare the public and achieve the certain social and political goals, and the completion of these goals is complicated without the usage of the mass media because of the necessity to persuade the public (Martin, n.d.). Thus, the modern products of the active relations between the mass media and terrorism which contribute to increasing the power of terroristic organizations are anonymous terrorism, the focus on violent terrorist attacks, and the terroristic attacks against media institutions to make them follow the terrorist instructions (Perl, 1997). Terrorists use the media to draw the public’s attention to the problem and receive the necessary resonance within the society. In spite of the fact that the media are closely associated with the development of terrorism and with stimulating the power of terroristic organizations, the media can also influence the public’s opinion in order to form the specific viewpoint and position against terrorism. From this perspective, it is important to control the usage of the media by terroristic organizations and to provide the required policies. References Camphuijsen, M., Vissers, E. (2010).

All About Serializing in Visual Basic

All About Serializing in Visual Basic Serialization is the process of converting an object into a linear sequence of bytes called a byte stream. Deserialization just reverses the process. But why would you want to convert an object into a byte stream? The main reason is so you can move the object around. Consider the possibilities. Since everything is an object in .NET, you can serialize anything and save it to a file. So you could serialize pictures, data files, the current state of a program module (state is like a snapshot of your program at a point in time so you could temporarily suspend execution and start again later) ... whatever you need to do. You can also store these objects on disk in files, send them over the web, pass them to a different program, keep a backup copy for safety or security. The possibilities are quite literally endless. Thats why serialization is such a key process in .NET and Visual Basic. Below is a section on custom serialization by implementing the ISerializable interface and coding a New and a GetObjectData subroutine. As a first example of serialization, lets do one of the easiest programs, but also one of the most useful: serializing data, and then deserializing data in simple class to and from a file. In this example, the data is not only serialized, but the structure of the data is saved too. The structure here is declared in a module to keep things ... well ... structured. Module SerializeParmsSerializable() Public Class ParmExample  Ã‚  Ã‚  Public Parm1Name As String Parm1 Name  Ã‚  Ã‚  Public Parm1Value As Integer 12345  Ã‚  Ã‚  Public Parm2Name As String  Ã‚  Ã‚  Public Parm2Value As DecimalEnd ClassEnd Module Then, individual values can be saved to a file like this: Imports System.Runtime.Serialization.Formatters.BinaryImports System.IOPublic Class Form1  Ã‚  Ã‚  Private Sub mySerialize_Click( _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal sender As System.Object, _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal e As System.EventArgs) _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Handles mySerialize.Click  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dim ParmData As New ParmExample  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ParmData.Parm2Name Parm2 Name  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ParmData.Parm2Value 54321.12345  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dim s As New FileStream(ParmInfo, FileMode.Create)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dim f As New BinaryFormatter  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  f.Serialize(s, ParmData)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  s.Close()  Ã‚  Ã‚  End SubEnd Class And those same values can be retrieved like this: Imports System.Runtime.Serialization.Formatters.BinaryImports System.IOPublic Class Form1  Ã‚  Ã‚  Private Sub myDeserialize_Click( _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal sender As System.Object, _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal e As System.EventArgs) _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Handles myDeserialize.Click  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dim s New FileStream(ParmInfo, FileMode.Open)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dim f As New BinaryFormatter  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dim RestoredParms As New ParmExample  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  RestoredParms f.Deserialize(s)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  s.Close()  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Console.WriteLine(RestoredParms.Parm1Name)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Console.WriteLine(RestoredParms.Parm1Value)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Console.WriteLine(RestoredParms.Parm2Name)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Console.WriteLine(RestoredParms.Parm2Value)  Ã‚  Ã‚  End SubEnd Class A Structure or a collection (such as an ArrayList) rather than a Class could also be serialized to a file this same way. Now that we have gone over the basic serializing process, lets look at the specific details that are part of the process on the next page. One of the first things you should notice about this example is the Serializable() attribute in the Class. Attributes are just more information that you can provide to VB.NET about an object and theyre used for a lot of different things.  The attribute in this code tells VB.NET to add extra code so that later on, everything in this class can be serialized. If there are specific items in the Class that you dont want to be serialized, you can use the NonSerialized() attribute to exclude them: NonSerialized() Public Parm3Value As String Whatever In the example, notice is that Serialize and Deserialize are methods of the BinaryFormatter object (f in this example). f.Serialize(s, ParmData) This object takes the FileStream object and the object to be serialized as parameters. Well see that VB.NET offers another object that allows the result to be expressed as XML. And one final note, if your object includes other subordinate objects, theyll be serialized too! But since all objects that are serialized must be marked with the Serializable() attribute, all of these child objects must be marked that way too. Just to be completely clear about what is happening in your program, you might want to display the file named ParmData in Notepad to see what serialized data looks like. (If you followed this code, it should be in the bin.Debug folder in your project.) Since this is a binary file, most of the content isnt readable text, but you should be able to see any strings in your serialized file. Well do an XML version next and you might want to compare the two just to be aware of the difference. Serializing to XML instead of a binary file requires very few changes. XML isnt as fast and cant capture some object information, but its far more flexible. XML can be used by just about any other software technology in the world today. If you want to be sure your file structures dont tie you into Microsoft, this is a good option to look into. Microsoft is emphasizing LINQ to XML to create XML data files in their latest technology but many people still prefer this method. The X in XML stands for eXtensible. In our XML example, were going to use one of those extensions of XML, a technology called SOAP. This used to mean Simple Object Access Protocol but now its just a name. (SOAP has been upgraded so much that the original name doesnt fit that well anymore.) The main thing that we have to change in our subroutines is the declation of the serialization formatter. This has to be changed in both the subroutine that serializes the object and the one that deserializes it again. For the default configuration, this involves three changes to your program. First, you have to add a Reference to the project. Right-click the project and select Add Reference .... Make sure ... System.Runtime.Serialization.Formatters.Soap ... has been added to the project. Then change the two statements in the program that references it. Imports System.Runtime.Serialization.Formatters.SoapDim f As New SoapFormatter This time, if you check out the same ParmData file in Notepad, youll see that the whole thing is in readable XML text such as ... Parm1Name idref-3Parm1 Name/Parm1NameParm1Value12345/Parm1ValueParm2Name idref-4Parm2 Name/Parm2NameParm2Value54321.12345/Parm2Value There is also a lot of additional XML there thats necessary for the SOAP standard in the file as well. If you want to verify what the NonSerialized() attribute does, you can add a variable with that attribute and look at the file to verify that its not included. The example we just coded only serialized the data, but suppose you need to control how the data is serialized. VB.NET can do that too! To accomplish this, you need to get a little deeper into the concept of serialization. VB.NET has a new object to help out here: SerializationInfo. Although you have the ability to code custom serialization behavior, it comes with a cost of extra coding. The basic extra code is shown below. Remember, this class is used instead of the ParmExample class shown in the earlier example. This isnt a complete example. The purpose is to show you the new code that is needed for custom serialization. Imports System.Runtime.SerializationSerializable() _Public Class CustomSerialization  Ã‚  Ã‚  Implements ISerializable  Ã‚  Ã‚   data to be serialized here  Ã‚  Ã‚   Public SerializedVariable as Type  Ã‚  Ã‚  Public Sub New()  Ã‚  Ã‚   default constructor when the class  Ã‚  Ã‚   is created - custom code can be  Ã‚  Ã‚   added here too  Ã‚  Ã‚  End Sub  Ã‚  Ã‚  Public Sub New( _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal info As SerializationInfo, _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal context As StreamingContext)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   initialize your program variables from  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   a serialized data store  Ã‚  Ã‚  End Sub  Ã‚  Ã‚  Public Sub GetObjectData( _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal info As SerializationInfo, _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ByVal context As StreamingContext) _  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Implements ISerializable.GetObjectData  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   update the serialized data store  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   from program variables  Ã‚  Ã‚  End SubEnd Class The idea is that now you can (and, in fact, you must) do all of the updating and reading of data in the serialized data store in the New and GetObjectData subroutines. You must also include a generic New constructor (no parameter list) because youre implementing an interface. The class will normally have formal properties and methods coded as well ... Generic PropertyPrivate newPropertyValue As StringPublic Property NewProperty() As String  Ã‚  Ã‚  Get  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Return newPropertyValue  Ã‚  Ã‚  End Get  Ã‚  Ã‚  Set(ByVal value As String)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  newPropertyValue value  Ã‚  Ã‚  End SetEnd Property Generic MethodPublic Sub MyMethod()  Ã‚  Ã‚  method codeEnd Sub The resulting serialized class can create unique values in the file based on the code you supply. For example, a real-estate class might update a the value and address of a house but the class would serialize a calculated market classification as well. The New subroutine will look something like this: Public Sub New( _  Ã‚  Ã‚  ByVal info As SerializationInfo, _  Ã‚  Ã‚  ByVal context As StreamingContext)  Ã‚  Ã‚   initialize your program variables from  Ã‚  Ã‚   a serialized data store  Ã‚  Ã‚  Parm1Name info.GetString(a)  Ã‚  Ã‚  Parm1Value info.GetInt32(b)  Ã‚  Ã‚   New sub continues ... When Deserialize is called on a BinaryFormatter object, this sub is executed and a SerializationInfo object is passed to the New subroutine. New can then do whatever is necessary with the serialized data values. For example ... MsgBox(This is Parm1Value Times Pi: _  Ã‚  Ã‚   (Parm1Value * Math.PI).ToString) The reverse happens when Serialize is called, but the BinaryFormatter object calls GetObjectData instead. Public Sub GetObjectData( _  Ã‚  Ã‚  ByVal info As SerializationInfo, _  Ã‚  Ã‚  ByVal context As StreamingContext) _  Ã‚  Ã‚  Implements ISerializable.GetObjectData  Ã‚  Ã‚   update the serialized data store  Ã‚  Ã‚   from program variables  Ã‚  Ã‚  If Parm2Name Test Then  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  info.AddValue(a, This is a test.)  Ã‚  Ã‚  Else  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  info.AddValue(a, No test this time.)  Ã‚  Ã‚  End If  Ã‚  Ã‚  info.AddValue(b, 2) Notice that the data is added to the serialized file as name/value pairs. A lot of the web pages Ive found in writing this article dont seem to have actual working code. One wonders whether the author actually executed any code before writing the article sometimes.

CRJS472IP5 - Research Paper Example l in the world containing information about more than 70 million criminals along with over 34 million civil prints (The Federal Bureau of Investigation, 2010). This paper discusses the reasons as why the integrated automated fingerprint information system works so well and the measures that are necessary to ensure the effectiveness of new and emerging biometric databases. The Integrated automated fingerprint information system features the fundamental practices for fingerprint biometrics including maximizing the quality of a fingerprint scan, ensuring liveness detection to prevent circumvention, measuring system performance and conducting scenario testing. The quality of the fingerprint scan is a vital aspect of the fingerprint biometric system design and is determined by the scanner resolution, scanner measurement area, scanner measurement technology, and the human and environmental factors. High quality fingerprint scans yield large numbers of biometric features. Fingerprint copies may be used in attempts to bypass the biometric system. The Federal bureau of Investigation prevents security bypasses by maintaining liveness detection in the integrated automated fingerprint information system. Liveness detection also referred to as copy protection ensures that copies of authorized user fingerprints are not used in the biometric system. Fingerprint copies include activated latent prints, two-dimensional and three-dimensional copies. The automated fingerprint information system features scanners with a built-in ability to detect latent, two-dimensional and three-dimensional copies. The Integrated automated fingerprint information system architecture complies with the Federal Bureau of Investigation architecture. And also regular reviews are conducted to ensure it complies with standards and guidance. The regular reviews ensure that the integrated automated fingerprint information system works with exceptional performance. The system also features service-oriented

Moraxella catarrhalis Assignment Example | Topics and Well Written Essays - 250 words

Moraxella catarrhalis - Assignment Example The infection is most common as a nosocomial infection or in children with weakened immune system and immunocompromised adults. Moraxella catarrhalis has a beta-lactamase positive strain that is highly resistance to antibiotic activity. Further, the bacteria has outer membrane surface proteins such as CopB, OMP CD, OMP E, uspA1 and uspA2 that limit the extent to which the normal protective mechanisms of the body and drugs affect the proliferation and existence of the bacteria in the system. The possibility of the bacteria, to cross the placental barrier and cause infections in-utero, has not been established. However, the high prevalence of otitis media caused by the bacteria is suggestive of a close relationship. Morphology: Moraxella catarrhalis is a non-motile single-celled bacterium which is oxidase positive and nonsaccharolytic. It is a gram-negative diplococcic bacterium that is non-sporeforming and catalase positive. It occurs as spherical organisms appearing in pairs or in linear clusters. Staining, sensitivity and treatment: The bacteria is negative on gram stain. The bacteria is not sensitive to common antibiotics that cannot break the beta-lactam ring. The most effective treatment involves fluoroquinolones, second- and third-generation cephalosporins, erythromycin, and amoxicillin-clavulanic acid antibiotics. At risk population, prevention and precaution: Children with weak immune system, pre-existing respiratory conditions and immunocompromised individuals are at high risk. There is no known vaccine against Moraxella catarrhalis. However, control measures include personal protective equipment in the hospital setting, such as gloves, face masks and hand washing to prevent contamination. In the hospital setting, the patients should be isolated in special rooms and anybody with weak immune status or children must not come into
