Malicious Attacks

Malicious attacks basically seek to exploit vulnerabilities in a network. These threats can be passive or active and have very negative consequences. The difference between active and passive attacks are that active attacks makes changes or modifications to the data or attempt to gain some type of access to the network, while passive attacks do not make changes to the system at all. According to Solomon, 2012, there are many malicious attacks and threats that can be carried out against the network, some of which are identified below: -Brute force attacks are one of the most tried and true attack methods where the attacker uses a software program to try all possible combinations of a password, security code or user ID, until one of them is successful. -Hijacking is another type of attack that involves the attacker taking control of a session between two machines and masquerades as one of them. This can involve man-in-the-middle, browser or session hijacking. Social engineering is another common attack where the attacker tricks the user in carrying out actions for them; for example, the attacker may obtain the user’s login credentials by posing as an IT Specialist which would then help the intruder gain access to the network. -Computer viruses act like a biological virus, where it infects the host program and could cause the host program to replicate itself to other computers. Some of these viruses have become smarter with the capability to combat malware-detection programs by disabling their detection functions. Trojan horse is a malware program that masquerades as a useful program They use their outward appears to trick users into running them; they look like programs that perform useful tasks but actually hid malicious code. -Rootkits are newer types of malware that modifies or replaces one or more existing programs to hide traces of attacks. -Spyware is a type of malware that specifically threatens the confidentiality of information. It does this by gathering information about a user through an Internet connection without the users’ knowledge. The impacts of all of the above attacks could damage or disrupt the system. It could also cause security privileges to be escalated to allow the intruder to access, modify or even delete private data. Additionally, as a result of any intrusion on the network, users would experience PC slowness, crashes and just no access at all to necessary resources. Malicious software is a major threat to the network, internal attackers, equipment theft and denial threats can pose even more of threat. Internal ttackers reside within the company and could be a cybercriminal, which is why it’s important to monitor the threats constantly and carefully. Equipment theft can also pose a serious threat because if equipment ends up in the wrong hands, confidential information could be exposed like account numbers or access codes. Lastly, Denial threats make assets or resources unavailable or unusable by flooding a specific port on a server rendering authorized users no access to import resources, wh ich could be a severe impact. If there is a vulnerability in the network or organization, then there is a possibility of a threat. If the vulnerability can be eliminated or addressed, the risks of attacks or threats are greatly decreased. Some common vulnerabilities are listed below according to Radack, 2013: -In the user domain where the user lacks the awareness of security policies or accidental violation of acceptable use policy in the user domain. -In the workstation domain there could be weaknesses in installed software and where unauthorized users could access the system. In the LAN domain, transmitting private data unencrypted, unauthorized network access and where malicious software can be spread -In the LAN-to-WAN domain there could be exposure and unauthorized access of internal resources to the public and loss of productivity due to internet access. -In the remote access domain is where brute-force attacks occur on access and private data and data leakage from remote access or lost storage devices. In the system and application domain there could be unauthorized physical or logical access to resources and weaknesses in server operating system or application software. -With VoIP there could be default manufacturer passwords still in place, insecure class-of-service settings and trunk access group restriction settings. The impact of any vulnerability is of course the possibility of a threat succeeding. A vulnerability is considered a weakness and any weakness in a network or organization will quickly be exploited by an attacker. The attacker is able to obtain information in all seven domains if one domain is not fully protected. For example, if a brute-force attack is deployed on a network and successful, it could affect users access to resources. Users could be in accordance with security policies and following correct protocol in order to protect the network as much as they can but if the brute-force attack is indeed successful, they efforts are thwarted. This is why it’s important to address each and every possible vulnerability in the seven domains of a network. If users are equipped with the right security tools; workstations are secure with strict access control policies; LAN servers are secured with various standards and guidelines; LAN-to-WAN security should maintained while allowing users as much access as possible; WAN domain has confidential encryption of data transmission; remote access domain has security controls applied according to policies; lastly if the systems/application domain has security policies, procedures and guidelines implemented in the various applications or systems, all vulnerabilities would be addressed.

Jazz in the 1920s Essay Example | Topics and Well Written Essays - 2500 words

Jazz in the 1920s - Essay Example This important event in history marked the importance of New Orleans as a regional musical center. The "Congo Square" became the breeding ground for what will become a very significant part of the American culture. In this place, the formerly slaves in the community were allowed to express themselves through music and other art form. Thus, they sang "work songs filled with irony, imagery, and love-relief from the tensions of their lives (American Popular Music 2005)." The blues, which is a precursor of jazz also flourished in the "Congo Square" giving way to the creation of jazz music. Compared to other types of music, jazz has its distinct characteristics. Jazz is characterized by blue notes, syncopation, swing, call and response, polyrhythm and improvisation. This repot will specifically look at the Jazz Age (1920s) and one of the most influential figure during that time. This paper will focus on the significance of jazz after the World War I and the significant places where it flourished. One section will give an account to the contributions of Louis Armstrong in jazz music. It will also briefly explain the situation jazz in the post World War II. A decade after the World... The 1920s, which is often regarded as the Roaring Twenties came to be known as the "Jazz Age." The decade witnessed the collapse of the America's traditional set -up. Its old perceived social conventions had ruined by the Great War but new principles developed. Jazz became the popular music embodying the "let-loose" social attitude during the period. It is during these times that people seem to get tired of the previous war and were expressing their relief through the use of mediums like music. Women, in particular, felt triumphant in their newfound freedom (that is, being granted the right to vote in 1920). They began to stick to a more liberated culture by bobbing their hair and wearing short flapper dresses. After the war, it became apparent that the public desired entertainment which led to the opening of public dance halls, clubs, and tearooms in cities. New dances like the Charleston are widely popular in dance floors and clubs. Black dances like the shimmy, turkey trot, buzzard lope, chicken scratch, monkey glide, and bunny hug were eventually adopted by the white public which implies the growing in the Arican-American culture. The new music, new dances and new fashions which dominated the new era outraged many as the Catholic Telegraph quoted:"The music is sensuous, the female is only half dressed and the motions may not be described in a family newspaper. Suffice it to say that there are certain houses appropriate for such dances but these houses have been closed by law (The Jazz Age 2006)." The Rise of Jazz Accordingly, two disparate, but important, inventions of the second half of the nineteenth century quietly had set the stage for jazz to capture the spotlight in American popular music by the 1920s-George Pullman's invention of

Juvenile Delinquency and Reoffense Essay Example | Topics and Well Written Essays - 3000 words

Juvenile Delinquency and Reoffense - Essay Example As the discussion stressers after serving the punishment handed down by the juvenile justice system, the juvenile delinquent is released from custody or supervision. The interest in the effectiveness of the justice system in reforming the individual gave rise to a wealth of literature particularly in the subject of re-offense. This paper aims to determine and discuss the nature of troubled youth re-offense and evaluate the policies aimed in addressing them. In reading this paper, one will come to know that re-offense is more commonly referred to as recidivism and that several socio-demographic, legal and policy-related factors are involved in its dynamics. From this paper it is clear that reoffending is more commonly known as recidivism and is legally taken to refer to the act of an individual committing an offense after being released from a correctional facility. The interest in determining the tendency of an individual to commit a crime again has given rise to several studies concerning recidivism. Maltz conducted a literature review and was able to identify at least 14 working definitions with the most prominent being re-arrest, resentence and readjust/reconviction. An individual is re-arrested once he is taken into custody after being released from custody or supervision after a certain time. This measure is argued to be dubious due to the fact that the arrestee may have been arrested for a delinquent behaviour that he did not commit. In short, the mere act of being arrested is taken to be indicative of recidivism. A child or an adolescent is considered to have been resentenced once he is subjected to a period of custody or superv ision.  

Database Applications Essay Example | Topics and Well Written Essays - 2000 words

Database Applications - Essay Example n system (CIS) is frequently a minor track inside the computer science area pursuing the study of algorithmic and computers procedures, comprising their principles, hardware and software designs, applications, as well as influence on society. Generally, a IS field puts emphasis on functionality over design (Kwame & Oduro-Kwarteng, 2009). This report presents the advantages and disadvantages of implementing the new software using database technology. In additional, this report will describe the relational database model and the benefits of a DBMS. Also, this report will provide a detailed analysis of the databases and new software implementations. The implementation of modern and up-to-date techniques of information technology in any organization tends to powerfully influence the growth, utilization, and application of business information. In this scenario IS uses a series of processes and methodologies that could be employed to facilitate the development and utilization of an information system. In addition, a number of developers have developed and employed engineering technique like that system development life cycle (SDLC) that is a systematic process of developing an IS by dividing it into phases that occur in series. Additionally, an IS could be developed in house (inside the business) or outsourced (outsourcing to outside firm). Furthermore, this development could be more successful through outsourcing certain parts or the whole system (Kwame & Oduro-Kwarteng, 2009). Kwame & Oduro-Kwarteng (2009) stated that in wide sense, the term IS refers to the communication among algorithmic procedures and technology. However, this communication could happen inside or across organizational boundaries. In addition, an information system is not simply the technology that a business employs, however it is a way in which the organizations implement the cooperation of the technology with the organization’s procedures. However, information systems are different from IT

A shift in the criminal justice system toward a crime control model Essay

A shift in the criminal justice system toward a crime control model - Essay Example Two models are currently being utilized in the United Kingdom which includes the crime control along with the process models (Feeley & Simon, 1992). The existing models represent the value systems within their society that are competing for first priority in carrying out activities in their criminal processes (Simons, 2007). The two models utilized within the United Kingdom usually have different motives with the crime control models being aimed at delivering effective crime controls whereas the process models aim at delivering justice to the criminals and their victims (Morgan & Morgan, 2008). The model on crime control is founded on the propositions that suggest that criminal conducts should be repressed and this is expressed as the most vital function that the process performs (Hillyard, 2004). This came about because there was great failure by the authorities to control criminal activities which has largely been perceived as the main reason for the breakdown in the countryâ€℠¢s public orders along with the ignorance for the legal controls that is currently exists (Feeley & Simon, 1992). ... In this model, the legal controls should come in handy after information has been collected, there have high rates of conviction or the police have been supported in their activities (Pelovangu, 2010). The model was established for the sole reason of dealing with the large number of criminal cases that were brought before the country’s judicial system rather that offering quality measures to help in curbing crime in the country. This model can be said to place a great emphasis on the capturing and prosecutions of criminals (Simons, 2007). On the other hand, the model of due processes is usually more concerned with the efficiency along with the structure of the existing law within the country (Feeley & Simon, 1992). The model mainly places emphasis on evidence rules, fact finding procedures that are impartial and also insists on an individual’s innocence until he can be proven to be guilty before a court (Hirsch & Ashworth, 2005). It mainly aims at preventing and elimina ting mistakes carried out within their country’s criminal system of justice. The model functions in a similar fashion to a factory that is devoted to its inputs, time, efforts and their abilities in securing justice within their system (Pelovangu, 2010). The new penology in the United Kingdom’s first came about in the 1970’s due to the neo-liberalism that was being experienced (Morgan & Morgan, 2008). It has been widely utilized in describing the changes that have taken place within the country’s penal system since it was first coined by Feeley along with Simon in the year 1992 (Garland, 2001). The new penology has also been widely utilized in describing the movements that are currently being witnessed between the state and the individuals

The Function of Management Planning Essay Example | Topics and Well Written Essays - 1500 words

The Function of Management Planning - Essay Example Within this organization, the planning involved selecting enterprise goals and department objectives than finding ways of achieving them. Plans depended upon the existence of alternatives, and then decisions had to be made regarding what to do, how to do it, when to do it and by whom it is to be done. Author Anderson has a responsibility to meet society's expectations in three concentric circles of responsibility (Arthur Andersen, 2007). The inner circle includes the business's clear economic responsibilities such as quality and safety and the provision of jobs and services. The intermediate circle expands the responsibility of businesses to make their policies and practices consistent with societal values in such matters as fair employment practices and a benign environmental impact (Accounting Industry, n.d.). The nature of ethical standards is one of the key issues to be addressed by personnel managers operating in a large corporation. There will gradually be a growing together of national practice on working hours, but it will take a lot longer for rates of pay to harmonies. Arthur Anderson adopts CSR because some moral justification comes from a value system that is independent of the business itself and where individual opinion can be sharply divided. SCR implies that employees at work should be honest and that claims about a product or service should be accurate. Ethical issues are corporate behavior and fair competition. In order to meet these objectives, Arthur Anderson uses systematic planning. Fair competition is achieved by adoption of specific ethical rules which guides management and marketing policies. Risk and uncertainty are minimized by planning and this is needed more today than before as social and economic conditions alter very quickly and careful planning enables an organization to prepare for change. Planning helps Arthur Anderson to define its purposes and activities according to fair competition rules. It enables performance standards t o be set and results can, therefore, be compared with the standard to enable managers to see how the organization is proceeding towards its goals. Planning is flexible to deal with a changing environment. Corporate behavior means that employees follow established norms combining their own judgment with the benefits of the corporation. In this case, the ethical responsibility of Arthur Anderson is to analyze social conditions and possible threats of their services for potential consumers. They should be well aware of the educational background of their customers and their expectations (Corporate Social Responsibility, 2007). Social responsibility translates into expectations that businesses comply with the spirit of society's laws and with the normative base that undergirds them. The social responsibility issues followed by Author Anderson are the attitude of management to labor and fair reward and use of shareholders capital. The attitude of management to labor is achieved through f air payment schemes and healthy corporate climate, training programs and promotion activities. Arthur Anderson provides additional training focusing on employee's motivation and work design programs to help worker identify their goal and professional development strategies.  

Greek Mythology and Platos Concept of the Soul Essay

Greek Mythology and Platos Concept of the Soul - Essay Example Platonic philosophy views the immortal soul and the body as separate entities. At death, the body decomposes and merges with the elements from which it was created but the soul is imperishable. This brings me to the point of linkage. To what degree was Plato influenced by Greek religious beliefs involving the immortality of the soul and what did Plato think of the afterlife compared to the earlier Greek religious beliefs about it? I cannot actually know this exactly but I can and will look at what Plato was reacting to. The Greek word for soul is psyche. Through the ages, the word psyche stayed the same but the meaning changed. My claim is that Plato’s idea of the soul differed from the earlier view expressed in Homer’s epics and other myths and he almost always chose the opposite position to Homer’s writings. Throughout the dialogues, Plato often argues against and almost ridicules Homer’s text, stepping outside the Greek societal box of thinking about the soul. Plato’s theory differs to that of the earlier Greek times because it portrayed the soul as being immortal and the means to knowledge. He did not associate the word psyche with de ath as did Homer. Hendrik Lorenz comments, â€Å"From comparatively humble beginnings, the word ‘soul’ undergoes quite a remarkable semantic expansion in sixth and fifth century usage. By the end of the fifth century -- the time of Socrates’ death-- the soul is standard thought and spoken of as the distinguishing mark of living things, as something that is the subject of emotional states and that is responsible for planning and practical thinking, and also as the bearer of such virtues as courage and justice.†1 Through the ages, Greek society associated the soul or psyche with the idea of death. The ancient Greeks’ religious beliefs were not prescribed in code on a set of tablets or papyri but rather passed down

The communist Manifesto Essay Example | Topics and Well Written Essays - 500 words

The communist Manifesto - Essay Example Marx and Engels influenced by the philosophy of Hegel, set out to change the face of the earth by calling the workers to unite to overthrow the capitalists. The Communist Manifesto was meant to provide the proletariat with required impetus for a social change. The Communists have no other interests but the proletariat. Since capitalism exploits the laborers but offers them only their subsistence wages, Communism is opposed to capitalism. The bourgeoisies' notions of freedom, culture, law, etc., are determined by their economical conditions. Communism, hence, abolishes eternal truths, religions and morality, for they are products of historical development. The core agenda is to acquire political supremacy by abolishing the private property and thereby uprooting the bourgeoisies. The proletariat, then, will centralize all instruments of production, and increase the productive forces. As class distinctions disappear, the proletarians will have an association, in which the free development of each will be the condition for the free development of all (Marx and Engels, Proletarians). Capitalism is characterized by private property, freedom of enterprise, profit motive, consumers' sovereignty, freedom of saving and investment decisions, and existence of competition, among others. Capitalist system necessarily envelops the private ownership of the means of production.

Battle of the Philippine Essay Example for Free

Battle of the Philippine Essay Thus, Nimitz had anticipated the two critical facets of Yamamoto’s strategic plan of having the battleship supported by aircraft carriers instead of the other way around – and Nimitz knew that the big battleship â€Å"Yamato† was far slower than any other Japanese battleship and Nimitz was also aware that the Japanese the smaller battleships were supposed to lure away the Americans away from the main contingent [7]. Hence, all of the Japanese plans, no matter how ingenious it was – did not work. Skirmishes between smaller contingents started early of June 3rd [7]. But June 4th was D-day time. Japanese planes attacked power plants and installations at Midway, the Battle of Midway has begun. The implications and losses for the Japanese forces were huge – within several minutes, the Japanese Navy had lost half of its carrier force – a force that had been considered to be manned by the Japanese Navy’s elite. Overall, the Japanese lost four vital aircraft carriers vital to their Pacific campaign and the majority of its experienced crew and air fighters. This was why military tacticians on both sides already knew that after the Battle of Midway, the tide of the war has turned in favor of the Allied forces [7]. The next battle fought on sea was the Battle of the Philippine Sea on June 18th to June 20th, 1944 [3]. It was here that Admiral Ozawa’s retirement and abstention from the battle that doomed any Japanese hope of stemming the tide against the American forces. The Japanese lost the Shokaku, Taiho and Hiyo (in each case about two-thirds of the ships’ company) and the oilers destroyed, as well as some 400 planes lost from the carriers [7]. On land, they were defeated in the Battle of Manila Bay and were forced to withdraw from the battle of Guadalcanal when the allies started their island – hopping campaign that had begun in the Solomon Islands. This pushed back the Japanese one island after another. The allies tactically isolated the Japanese major forces in the pacific located at Rabaul. Finally the Japanese were defeated once again as the allied forces pushed them back towards the Philippine islands sea, and the battle of the Leyte Gulf in October 19, 1944. That day, the Americans, headed by General Douglas MacArthur fulfilled his promise of returning to the Philippines [5]. From Leyte Gulf, the Americans coordinated with the existing guerilla forces made up of joint American and Filipino recruits. Finally, on February 4, 1945, the Americans entered Manila and the Yalta Conference was held in USSR [5]. From there the recapture of the Marianas and the Philippine islands were used as a take – off point to advance to Japan’s homeland, and on to the invasion of Iwo Jima and Okinawa. However, in spite of the aggressive military campaign and successive defeats the Japanese suffered from the hands of the allied forces, the emperor refuses to budge and accept defeat to end the war. Instead, the code of BUSHIDO was once again called upon and young Japanese men called to duty went on suicidal missions purposely using their planes as weapons against aircraft carriers and other enemy targets. During that time the US had developed an experimental bomb – the A-bomb and was used as a last recourse to make the Japanese government surrender and stop the continuing carnage. On July 16, the Potsdam conference started. Meanwhile, the first atomic bomb is exploded in a test at Alamogordo, New Mexico. July 26, the Potsdam Declaration is delivered to Japan. On August 2, the Potsdam conference ended [7]. On August 5, 1945 the US dropped the atomic bomb on Hiroshima. Still, the Japanese government did not heed the warning. August 8: Russia declares war on Japan. On August 9, another bomb decimated the city of Nagasaki. Finally, Japan surrendered on August 14, 1945 and accepted the Allied terms [7]. VI. Conclusion The passion and ferocity displayed by the Japanese soldiers’ generals and rank and file throughout the entire course of World War 2 proved to the whole world how ready the Japanese were in embracing and enforcing this war. Their cultural mentality and their refusal to budge even at the expense of their young people’s lives showed how tenacious they intended this war would be fought. Their disdain of soldiers who have surrendered during the war – particularly during the â€Å"Bataan Death March† and their treatment of captured American and British officers bolster their â€Å"Bushido† mentality. Japanese soldiers were trained to fight or die. These soldiers, no matter what the cost would offer their lives and commit â€Å"Harakiri† rather than be captured. Hence, they only have the lowest of regard for those who surrender or for those who allowed themselves to be captured. There was no mistaking in assuming that the Japanese prepared and were ready for generations – from the late 1900s into the 20th century that they were trained to go to war and conquer.

Britain And France Sought To Appease Hitler History Essay

Britain And France Sought To Appease Hitler History Essay Britain and France sought to appease Hitler not merely because it was militarily, economically and politically rational to do so, but because of personal judgments made by Chamberlain. The appeasement policy was a policy adopted by Britain and France and it was a major player in the outbreak of the war. Appeasement was first introduced in the mid 1930s by Stanley Baldwin who was then the British Prime Minister. But it was Neville Chamberlain who changed this appeasement policy when he ascended to power in 1937. The British government defines appeasement as the settlement of issues through negotiation and compromise. The British were very committed to this policy and they followed it confidently with the hope that it will reduce the chance of a world war. Neville Chamberlain was the greatest advocate and pursuer of the appeasement policy. He sought this appeasement so as to conciliate with Germany so as to have a stable Europe  [1]  . His personal view was that Germany would be satisfied with what he offered and especially the restoration of its former colonies. There are reasons that made Chamberlain seek appeasement with Hitler. One of them is that he represented the British citizens who did not want a war as they were in the process of healing the wounds from world war one. Also he did not want to go to war with Germany because the fall of Germany would mean the victory of the Soviet Union and the spread of communism therefore. Both he and the British citizens did not want this happening. So Chamberlain was trying as much as he can to avoid a war with Germany and at the same time the spread of communism. The appeasement policy that Chamberlain campaigned for was merely to avoid war. But it can also be seen as a strategy that he used in order to gain some time of rearming his forces. Though he really wanted to avoid the war, there came a time that he knew that war was in evitable. It was only after the failure of the negotiations between him and Hitler that he declared war against Germany  [2]  . Chamberlain felt that he had been betrayed by Hitler and that his appeasement policies were failing him. That is when he decided to take on a hard line approach towards the Nazi. Britain and France began rearming themselves. Italy on the other hard invaded Albania in April of 1939. It was Hitlers invasion of Poland that made these two countries declare war and Second World War officially began on 3rde September 1939. The Versailles Pact which had been signed after the First World War with an aim of ending all wars was greatly hated by the Germans  [3]  . It was signed by the four nations. It was argued that the treaty if it were to stand wound ruin the economic status of Germany. The Germans were not allowed to participate in the negotiations and the big three countries which participated each had its own personal goals. The Germans felt they were humiliated with the French feeling a sense of insecurity. The British championed for the reestablishment of world trade and they wanted nothing more while the Americans were to give up their principles and ideals of self determination especially on matters that concerned Germany. With all these issues in place, a disaster was inevitable  [4]  . This treaty is seen by some historians as the lead cause of the Second World War. The countries participating signed it for their own benefits without considering other countries in Europe. France wanted revenge to the Germans. Britain signed it just to prevent a war while America looked at the bigger picture of making more money  [5]  . Many Britons saw hope after the signing of this treaty. They wanted to avoid another war and that is why the British government had to give in to the demands presented by Hitler  [6]  . The British economy was fairing very badly hence Britain was not ready for a war. It was not even in a position to fund and rearm its military force due to the bad economic status. So Chamberlain tried as much as possible to avoid a war with Germany. The way Hitler was progressing meant that there was not even time for Britain to organize war strategies and prepare its force. So Chamberlain had to find a way of avoiding war and/or gaining sometime to rearm the military. The only solution present was appeasement  [7]  . Hitlers main aim was to make Germany as super power and a united Germany. He also wanted to enlarge the Germany territory through what he called recapturing of lost territories  [8]  . Hitler believed that German will become strong again only through the use of military aggression and war. He directly challenged the Versailles treaty in 1934 by rearming his armed forces and preparing them for war. This he did through production of tanks, submarines and aircrafts in huge masses. When it was announced that Hitler was rearming his military forces, which was in conflict with the Versailles pact, Britain and France protested to the League of Nations with the hope that it can be stopped  [9]  . The League of Nations did not try to stop these aggressive rearmament plans by Hitler on the grounds that there were no military or economic sanctions that had been imposed. It was due to the appeasement which made Hitler more confident. In short France and Britain simply turned a blind eye on this public breach of Versailles treaty. The Anglo-German Naval agreement that was signed in 1935 was the form of appeasement of the British towards this rearmament. This was because the agreement acknowledged that the rearmament of the German should be limited to only 35% of the fleet owned by the British. The agreement which was made by the British solely without the agreement from Italy and France became the first time that Britain agreed and approved a German contravention of the treaty of Versailles. It was after 1936 that Hitlers confidence of waging a war climaxed. This was because he had accumulated enough mercenaries of war and also had fully prepared his military force. He was confident that France and Britain as the appeasers would not stop him. He did this knowing very well that he was flouting the Versailles treaty. Rhineland was a strategic military position that could determine the fate of Germany. It was a point where by the French could use to invade and strike then heart of the Germanys power. It was due to this reality that Hitler ordered its reoccupation and remilitarization. This was an open breech of the treaty of Versailles but France and Britain just turned a blind eye. Hitlers aim of doing this was to stop any attack from France. The Rhineland could have been used by France to attack Germany. Remilitarizing it meant that Frances attack on Germany would be immediately repelled by the Germany forces. But they did not even try to stop him because he was taking back what belonged to Germany originally. At this stage, France could have stopped the reoccupation of the Rhine region but she did not want to start a war with Germany due to the lack of support from the British  [10]  . This made Hitler even more confident that he even saw an opportunity to challenge the balance of Europe po wer. The appeasers had no say about Rhineland because they argued it was a Germany territory and it could do whatever it wanted with it including having its military force there. Even though, Hitler had ordered his army to withdraw with immediate effect if the French intervened. But since there was no any intervention from the French he became more confident. Chamberlain thought that by allowing Hitler to take over the region that formally belonged to Germany, he would at least stop there. Hitler invaded Austria in 1938 and he declared Anschluss. In doing this he was breaking the Versailles treaty. The Australian chancellor at the time pleaded with France and Britain to help but these two countries did nothing about it. Chamberlain sent a protest note to Berlin  [11]  . he addressed the cabinet after Hitlers army crossed the border and he blamed both Germany and Austria. Even though, he condemned strongly the methods used by Hitler to annex Austria  [12]  . The annexation of Australia in 1938 was seen as a solution to the problems that faced the war oriented Germany economy. Hitler saw it as a perfect opportunity of fulfilling his goal of uniting all the Germans within the Reich. The Austrian Nazi staged demonstrations following orders given by Hitler and this proved a perfect opportunity for Hitler to send his troops to occupy Austria. The appeasers did nothing more after this than mere protests. The link up with Austria strengthened the friendship between Germany and Italy and it also gave Hitler a direct route to southeast Europe. Britain and France appeasements gave Hitler more confidence again to conquer Europe. After Austria, Czechoslovakia was next. Due to the success that he had achieved before, he demanded that Sudetenland be incorporated into the Third Reich because it was the most industrialized and wealthiest region in Czechoslovakia. And since the appeasers were afraid of a war break out, they pleaded on the president of Cz ech, Benes to come into as compromise with Hitler. It was with this regard that Chamberlain met Hitler in an attempt to resolve the issues. He met him three times on separate occasions. It was at Berchtesgaden, where Hitler promised Chamberlain that the case of Sudetenland would be self determined. But in Godesberg, Hitler changed his stand and he instead demanded the immediate incorporation of Sudetenland into the Third Reich. This demand made Chamberlain very angry and on his return to Britain he began organizing the army in prepared ness for war. Czechoslovakia president was forced to sign the agreement. Chamberlain and Hitler signed another agreement to imply that Britain and Germany would never be at war with each other again. The invasion of Czechoslovakia as a whole is what opened the eyes of the appeasers and they saw that no matter how much they tried to appease Hitler, war was inevitable. After giving in to all the demands made by Hitler and his continual invasion of Europ e, the appeasers realized that the appeasement policy was a failed policy. Hitler went on to invade Poland ignoring the ultimatum that he had been given by Britain and France to stop the invasion. It was after this that the appeasers declared war on Germany  [13]  . It was the 1938 crisis whereby the Sudeten Nazis started demonstrations and causing trouble led by Heinlein and under orders from Hitler which is seen as the true appeasement because Chamberlain intervened. Henlein demanded union of Sudeten with Germany. This was what led to the meeting at Berchtesgaden which was held on the 15th day of September. Here Hitler and chamberlain met and Hitler threatened to wage a war but he promised Chamberlain that it would be the last problem to be solved. Chamberlain saw Hitler as a man who can be trusted and in his intervention he persuaded the president of the republic of Czech to hand over Sudetenland to the Germans. In doing this, chamberlain thought that this was the last demand that Hitler would ask for. The Godesberg meeting between Hitler and Chamberlain took place in 22nd September 1938. Here Hitler asked for more demands which Chamberlain refused to offer. It was this mistrust which Chamberlain saw in Hitler that he knew that war was definitely inevitable. Chamberlain did not see Czechoslovakia as an issue that could result to war. He had simply assumed that it was just a conflict between two neighboring countries and that their conflict could not result to a world war The appeasement policy can be said to have climaxed in the Munich conference held in September 1938 where by Britain and France finally gave Hitler the go ahead to take over Sudetenland. This was a conference held in Germany to discuss the fate of Czechoslovakia amid the demands made by Hitler. The countries that were present were Italy, France, Germany and Britain Notably, Czechoslovakia was not present. The Munich pact was signed and this allowed Hitler to take over Sudetenland This was the center of Czechoslovakia as it was where most of its banks and border defenses were situated. By signing this pact, the European powers meant that Hitler was free to take over the whole of Czechoslovakia. By signing this pact, Chamberlain thought that Hitler would be finally satisfied and stop making more demands The agreement was proposed by Mussolini though it is claimed that it was prepared by the German foreign office. Czechoslovakia felt betrayed by France and Britain because it was informed to either accept the agreement or fight its more powerful neighbor all by its own  [14]  . The pact was signed on September 30th. When Chamberlain returned to London he gave his famous peace for our time speech. The crowd that had gathered in London was very delighted to hear that peace has finally been found and that there was no prospect for war  [15]  . The main reason why Britain and France embraced the appeasement policy was because they did not want the whole of Europe to be dragged into a world war by Hitler. It was a policy being persued due to the lessons learnt from world war one. Appeasement policy can be seen as a bad policy that was aimed at achieving world peace while sacrificing some countries like the way Britain and France did to try and appease Hitler at the mercies of Czechoslovakia. Germany was becoming stronger while the countries that were under its threat had no say. There was much tension in Europe as most countries feared the rate at which Germany was becoming strong.. The availability of more resources from the conquered countries strengthened the Germany economy and therefore it could sustain a war. Though the appeasement policy led to the strengthening of Germany, and the breakout of war, there are other reasons why France and Britain adopted this policy. These two countries were faced with economic problems in the 1930s. The British economy was severely weakened by the Wall Street crash of 1929 which made the government put the rearming of its armed forces on hold. Chamberlain wanted as much as possible to avoid war. That is why he adopted the appeasement policy. On the other hard, France was not in a position to maintain a war. It needed the support of Britain. It is because of this that it followed Britain in seeking the appeasement. This was because he wanted peace and stability that would allow economic growth for the whole of Europe. The Britons had a positive attitude towards the appeasement in the hope that it would reduce the chances of a war outbreak. Thus it can be concluded that appeasement was a British government policy that was fully supported by the citizens. Britain did not want a war between it and Germany. This was because it was threatened by communist USSR and not because it feared Germany. In case Germany fell, there was a possibility of spread of communism and Britain did not want this to happen. That is why it was in the favor of appeasement policy. Another fear that embraced Britain was forming a coalition with USSR which was its bitter rival. That is why Chamberlain desperately sought for appeasement at the mercies of other countries just to make sure that they did not join hands with USSR in a war against Germany  [16]  . The signing of the Munich agreement is viewed by many as a betrayal especially by Britain. What Chamberlain was doing is to buy some time to rearm British forces. Hitler on the other hand thought it as a weakness and a sign of fear of the appeasers  [17]  . This was a great mistake as all that the appeasers wanted was to preserve the world peace. This is what made him bold and gain confidence and a sen se of security. Therefore the blame for the outbreak of Second World War can only be largely placed on Hitler and not on the appeasers. This is with regard to Hitlers goals and determination to make Germany a super power and to do so; war was inevitable as he had severally claimed publicly. Hitler had managed to convince the appeasers that he had no any intentions of aggression through his peace propaganda. This had in a way fooled Britain and France who were not in favor of a war but wanted world peaceful coexistence. The appeasers continued to adopt the appeasement policy and this assured Hitler that they would do anything just to avoid a war. This made him think that he could continue to expand his demands and the appeasers would still continue to give in to them. It was this appeasement policy that gave Hitler a foundation and a base to increase the demands after every successful conquest that he achieved. Conclusion There are many opinions and views about the appeasement policy with some critics saying it was a betrayal and sacrifice of some nations for the benefit of others. Others say that it was Chamberlains strategy of buying time to rearm Britain. But from Chamberlains point of view, all that he wanted was to avoid another world war. It is not the appeasement policy that triggered the world war two but instead it was the greed of Hitler to enlarge the German territory and make Germany a superpower. The failure of the appeasement policy was because it was only Chamberlain who fulfilled his part of the bargain. He was convinced, on trying to appease Hitler that he (Hitler) was an honest trustworthy and honorable man which was a mistake and a misjudgment on his part.

Technology and Art :: essays research papers

Does size matter? In the world of technology, it all depends on the consumer. The first generations of televisions were designed in a very simple form. Most were square, made of wood, and had a round dial to change channels. Nowadays, we have many different shapes and functions for televisions. Culture and technology have had a large impact on the development of the design and features of the modern television. The design of the television has drastically changed over time. For example, the 1948 Fada model was large in volume and it had a convex and oval shaped screen. It had four knobs used to tune and change channels. The structure was made of wood and it included a fairly large speaker underneath the twelve inch screen. The television only had access to thirteen channels. The dial simply shows that the culture did not have access to many channels. Past televisions were simple because the lifestyle was simple. People did not need hundreds of channels and massive screens to be satisfied. Modern televisions now come in various sizes and have features to accommodate the consumers. For example, the Philips-Magnavox 50FD9955 is thin and has a fifty inch (diagonal) rectangular flat screen. This television can be placed almost anywhere imaginable. It can be hung on a wall or even on the ceiling. The large size of this television represents modern society’s need for bigger and better things. It has an on/off button, two channel buttons, two volume buttons, and other various buttons for adjusting the color. The channel buttons on the modern television represent the unlimited number of channels. The structure is made of metal and plastic and it includes a speaker on each side. The plastic body is easier to mold, cheaper to produce, and easier customize the color. The television comes with standard audio/video jacks, cable jacks, and an S-Video jack to accommodate VCRs, DVD players, camcorders, and other accessories. These additional features did not just appear overnig ht, they developed with society to satisfy their needs. Television is designed around its culture. In the past, watching television was a way for families to be together. Everyone gathered around the television and watched the same show. Families did not have the luxuries of owning more than one television and having hundreds of channels. Today, almost every room in the house has a television. People in different rooms are now able to watch their own shows.

Race: Biological or Cultural? :: essays research papers

Through research of DNA samples, scientists have been able to declare that race is not biologically constructed due to the similarities between human genes. Nevertheless, in reality, people still emphasized on biological aspects such as skin color, or hair texture to categorize others into different races. This in turn, denied the true identity of race, which it is culturally constructed. Ethnicity, by definition is also culturally constructed, therefore it greatly resemble race. There is no real clear line to distinct the two. According to Nicholson, encounters between explorers, such as Christopher Columbus and Henry Hudson, and Native Americans were always friendly. There was no â€Å"expression of hostility based on physical appearance† (Nicholson 15) between the two groups. When there was any hostility, it was not based on physical appearance, but rather more of culture practices or values. Cannibalism, for example, â€Å"seems to take place without any regard to race, creed, or religion.† In another case, Nicholson mentions that during the Crusade, about ten thousands Jews were massacred by Crusaders. It â€Å"was a religious slaughter without racial implications.† (Nicholson 26) Through these examples, we can see that Nicholson suggested that race is not scientifically valid because people did not judge others based on physical appearances, but the notion of race is mainly described by one’s skin color or hair texture. Nicholson’s arguments coincided with modern scientific views, which conclude that race doesn’t exist, due to the fact that DNA inside people with different skin color and hair texture is 99.9 percent similar. Therefore, the notion that race is biologically constructed in invalid. Social reality of race simply refers to the fact that people still believed that races are based on physical traits such as skin color or hair texture to judge others. However, what they are doing is stereotyping which lead to discrimination and racism. Also, their actions denied the fact race is culturally constructed, meaning people have different customs, religions, and values from culture to culture. The patterns of biological variation among humans are extremely complex and constantly changing. All of us could be classified into a number of different "races", depending on what genetic traits are emphasized. For example, if you divide people up on the basis of stature or blood types, the geographic groupings are clearly different from those defined on the basis of skin color. Focusing on such deceptive distinguishing traits as skin color, body shape, and hair texture causes us to magnify differences and ignore similarities between people.

Suggest a mechanism for this reaction. Which of the two ox ygen atoms is most likely to be eliminated and why? Answer First, there is protonation of the 3? –OH group, then a 3? carbocation is formed via loss of H2O. Then there is a nucleophilic attack of the carbocation by the 2nd –OH group. The 3? OH group is the one eliminated in all likelihood because its removal involves the formation of the more stable 3? carbocation.

Ichabod Crane and Abraham Van Brunt Essay

In the short story of The Legend of Sleepy Hollow you will find two very different men, Ichabod Crane and Abraham Van Brunt, competing against each other for but one woman’s hand in marriage, Katrina Van Tassel. Katrina Van Tassel was a ravishing young lady of only eighteen and the only child of a very wealthy farmer named Baltus Van Tassel. Her father paid little attention to her other than to be proud of her good doings when they were praised by others. Because of her beauty, along with the wealth of her father, Katrina had the interest of many men. Although these men were driven away in defeat by a man named Abraham Van Brunt, whom also had a strong interest in Katrina. Abraham Van Brunt, also known as Brom Brunt, was tall and extremely hansom with dark curly hair. He was described as muscular and strong, thus he was given the nick name Brom Bones by the townspeople. Brom was known for his rambunctious personality, his love for pranks, and his admirable great skills on horseback. He was known as the â€Å"village hero.† He wanted Katrina’s hand in marriage, not because he loved her, but because he was determined to inherit the wealth of her father Baltus. Brom managed to scare off all the other suitors of Katrina with violence and physical confrontation. He had no competition! That is until Ichabod Crane came along. Ichabod Crane was a shy school teacher who had traveled from his home state of Connecticut to Sleepy Hollow, New York. He came to teach the children about the area. He was known to be a strict teacher, but not cruel. Ichabod was described as a lanky man; tall and thin with big hands and feet and also a rather large nose. He was said to be an awkward n clumsy man. Although he was a rather thin man, he was capable of eating plenty and was often looking forward to do so. He was an extremely superstitious man, so much that he believed in every myth, legend, and tall tale to be truth. This resulted in him easily being scared of anything that reminded him of ghost, goblins, witches, demons, etc. Despite his awkwardness, Crane was a very sociable man. I guess he had to be considering the fact that he would live at the homes of the townspeople, a different one every week. He was said to be a kind man. He would sometimes walk his students home from school, he would play with some of the bigger kids, and he would even help farmers with all of their farming duties. Many women took a liking to Ichabod because he was known to be kind and gentlemanlike. Also, he loved to sing and he had a beautiful voice and the ladies loved it! In fact, his voice was so beautiful that he also taught the townspeople to sing and also led the choir at the village’s church. Katrina was a student of Ichabod. When he had first met her, like many others, he was mesmerized by her beauty. Although it wasn’t until he had met her father and seen her farmhouse that he felt he was in love with her. To me it seemed as if he had just fallen in love with the idea of inheriting her father’s wealth, but the story says he was in love with her and wanted her heart, not just her wealth. Of course, this didn’t sit well with Brom Brunt at all, and he would try to chase Ichabod off. But Brom couldn’t do it in his usual way of violence, because Ichabod had a way of avoiding physical confrontation with him. So instead, Brom would use his second best skill, pranks! Knowing that Crane was a superstitious man who was easily scared, Brom would begin to taunt and tease him with scary stories, including the town’s most famous one, the legend of the headless horseman. This would eventually mark the end of Ichabod Crane. The story tells that one night after attending a party held at the Van Tassel home, when Ichabod was walking home, he had an encounter with what seemed to be the headless horseman. He was never to be seen again. Some believed that it was actually the headless horseman himself who had taken the life of Ichabod, but others believed that is was just Brom Bones in costume out to get what he wanted, Crane gone! As you can see, in comparison, these two men were very different from each other. Quite the opposite I’d say. The only thing that they shared a common ground with each other would be their desire for the Katrina Van Tassel and her inheritance. Even then, they would attempt to woo her in very different ways, Crane with his songs and his stories of superstitions, and Brom with his violence and strength. Besides the way these men look, their personalities and even their interests and talents were very different. I’d say Brom Bones was a man of good looks and brawn but rather rowdy, rude, and perhaps cruel. While Ichabod was a sensitive man with a kind heart and although he was lanky and awkward looking he was a gentleman with good social skills.

Dehydration Essay

Passing out, lethargy, constipation, dry mouth and even dry eyes are very few symptoms In the long list of signs to tell us that we are dehydrated. Being dehydrated Is potentially very bad and If not taken care of a person can end up In the hospital or even dying. Many things can cause dehydration Including drinking too much alcohol or simply not drinking enough water. Without ample amounts of water our bodies cannot function correctly, and being made up of 70% water it is understandable as to why this is the case.All people suffer from dehydration, it does to affect one age group more than another, and likewise it does not affect one race or gender more than the others do. Plainly, put, If enough water Is not drank everyday than a person Is at risk for becoming dehydrated and developing symptoms that can be quite uncomfortable. First, some of the functions of water in the body are to keep everything moist, from our eyes to our mouths, and even our Joints. Imagine trying to eat food without the assistance of the saliva our bodies produce, it would be very difficult to have to swallow dry, chewed up food.Urine becomes dark yellow, with a strong ammonia meal and constipation Is common; the lack of water causes the stool to become more solid and less liquid-y because the body Is pulling water from every available resource. The recommended amount of water that the average person should drink is eight – z cups of water per day. That is a half-gallon of water every day that people are supposed to be drinking, more often than not soda and coffee is being drank instead, which sure they have water in them†¦ Just not the recommended amount that we need.Next, dehydration affects people of all ages, from little children to grown adults, to even the elderly. In children, dehydration causes tiredness and grumpiness, even the sensation of being hungry, or the craving for something unknown. In adults, dehydration can mean different and more serious side effects suc h as passing out or getting dizzy when standing up. In the elderly, dehydration, in my opinion is the worst time to see it. I think that older people need more water in their bodies because they dispel more In the given day.They may not have bladder control, especially If they are hooked up to a urinary bag, and not necessarily know when they have lost all of their water. Nursing homes help the elderly with this a lot of the time cause the people cannot do it on their own. For everyone else however, it is important to make sure we drink the vital amount of water to remain healthy. On another note, when a person is dehydrated they lose important vitamins and nutrients known as electrolytes.When children have a fever or diarrhea, pediatric is a good drink to give them because It Is packed full of electrolytes, It Is k for adults to are sodium, potassium, and chloride. These electrolytes help maintain blood pressure. Body movements require electrical currents to run through the body an d these charged ions make this possible. Sodium and potassium are positive ions that both function to provide nerve transmission, muscle contractions, and fluid balance. Chloride is a negative ion and its main function is to provide fluid balance.Not having enough sodium in your body can cause muscle cramps, but table salt is a quick fix of this deficiency. Not enough potassium can cause fatigue, and once again can be fixed quickly and simply with eating bananas. Finally, a chloride deficiency can cause a potassium or sodium deficiency. When being active and playing sports or Just being outdoors, drinking sports drinks like Storage can help maintain proper electrolyte balances. Yet again, many things cause people to lose water from their bodies at different speeds.Sweating causes us to lose water at significant speeds because our skin seeps water to cool us down on a hot day. If it is scorching hot outside and a person just stops sweating, this is a sign of dehydration and they shou ld seek out a water source fast. Similarly, alcohol makes us lose water quicker on many levels because it heats people up from the inside causing them to sweat and it depletes electrolytes from our system. Drinking water in between alcoholic beverages can help a person avoid a hangover because they are staying hydrated while drinking.Caffeine on the other hand, speeds up our heart rate, causing us to urinate more that in the end is causing us to lose more water than we would without the caffeine. These things can lead to dehydration of the person ingesting them does not know what the symptoms are and how to counteract them. Finally, making sure that a person does not become dehydrated is important, even more so for people less than healthy. A person with a hole in their heart is more susceptible to symptoms of dehydration than a healthy person, and the same with elderly. Everyone is responsible for the amounts of water they drink each day.We need to instill in children at a young ag e that staying dehydrated is important. It is also important to work it into the daily routine, and make it habit to drink 64 ounces of water per day, and keeping an eye on electrolytes as well. Eating lots of fruits or vegetables or water-based foods can help a person increase their water intake without necessarily drinking as many glasses of water. Overall, there is more than enough water on this planet, and foods that contain water for everyone to be able to survive. If someone becomes dehydrated in my opinion, it is because of his or her own personal neglect.Should this be the case that person needs to understand the importance of staying hydrated and how this simple task can solve many ailments. Staying hydrated can make a person feel Just a little bit better in many aspects, maybe their Joints are moving Just a little bit better, or they do not have to use eye drops 10 times a day. If you do not stay hydrated regularly already, you should try it Just to see what kinds of thing s it could do for you. Perhaps a little more energy for those long days would be nice.

Introduction of Information Technology Related to Hotel and Restaurant Management

Chapter II Review of Related Literature Students look forward to the opportunity to choose their academic plans and classes. According to the enhanced cognitive engagement theory, allowing students to choose which classes they enroll in increases motivation and independence which in turn increases a student's cognitive processing and performance, however, the task of course selection is very complex with multiple considerations, most of which overlap with one another.Students are influenced by the different academic portions of the class such as the value of the content, the structure, and the workload. They also have to decide what is important to them with regards to their interests, personal academic goals, and their schedule. But students do not make these decisions alone because they do occasionally seek advice from their family, faculty, and/or friends. Not all of the different considerations of a course are as influential as others, but it is important to know what students wa nt from their classes, what they expect of themselves, and who they will listen to.Educators and schools need to know this information; especially those of elective courses so they can meet the needs of students and have them continue to enroll in their class. More importantly though, if teachers can adapt their classes to better meet the needs of students the students will be more engaged which will increase their comprehension and excitement for the curriculum, which should be any teacher's ultimate goal. The following paper provides further analysis on the most current research based on influential factors of course enrollment.The first section deals with the academic considerations such as, value and execution, teacher, and workload. The student must also take into consideration their own personal preferences of their interests, capabilities, gender, and their schedule, which is explained throughout the second section. The third component deals with the influential sources a stu dent may listen to including their family, peers, and the faculty at their school. Finally, the gaps and limitations of the research are discussed along with the need of further research. Reference: (http://voices. ahoo. com/the-factors-influence-students-decision-for-8258751. html) Each course is a unique mix of many different ingredients — from subject matter, to fellow students, to the jobs it leads to. The following points can be used as a checklist of things you need to find out about courses of interest. Think about what you will learn and how you’ll learn it . Subject matter is the first step to success is studying something you are interested in. Intellectual style, some courses are mainly ‘quantitative' (how's your maths? ), others are ‘verbal' or language based.Some encourage you to have your own ideas, ask the big questions and find out about the world. Work patterns, courses vary in the time students spend in lectures, tutorials, studios and lab classes and completing self-directed study. Some courses also have an industry-based learning component. If it is tough to study and pass. Some fields of study are notoriously tough, with high failure and drop-out rates. How long they take, VET certificates generally take a year or less of full-time study, diplomas and advanced diplomas around two years and bachelor degrees three or four years.Double degrees, ‘honours' courses and part-time programs will take longer. How much choice they allow, some courses require all students to complete the same ‘core’ subjects, while others allow you to choose a lot of electives. International study opportunities, optional summer study tours or study abroad and exchange programs may offer credit towards some courses. How you can study, courses may be offered full time, part time, by distance education or on an accelerated trimester schedule. Not all courses offer all options.Quality, regardless of their subject matter, course s should be well run by experienced staff and (if applicable) meet industry standards.Reference:(http://gooduniguide. com. au/School-Leavers/Choosing/How-to-choose-a-course) Choosing the course that you are going to study for the next 3 or 4 years can be difficult. Course content will vary between institutions and it is important to check that the courses you are applying for cover the topics you are most interested in. Reference:(http://www2. warwick. c. uk/study/undergraduate/apply/choosing/) The number of courses you take each semester will be one of the most important factors affecting your success at school. It's easy to get caught up in the excitement of choosing courses at the beginning of semester when you're rested and ready for a challenge. But you need to flash forward to mid-term – when the day-to-day reality of classes, assignments, reading, essays and exams will be all too real.

Wensha vs Yung Case Digest

G. R. No. 185122 August 16, 2010 WENSHA SPA CENTER, INC. and/or XU ZHI JIE, Petitioners, vs. LORETA T. YUNG, Respondent. A petition for review on certiorari under Rule 45 of the Rules of Court filed by an employer who was charged before the National Labor Relations Commission (NLRC) for dismissing an employee upon the advice of a Feng Shui master. Facts: Wensha Spa Center, Inc. (Wensha) in Quezon City is in the business of sauna bath and massage services. Xu Zhi Jie a. k. a. Pobby Co (Xu) is its president,3 respondent Loreta T. Yung (Loreta) was its administrative manager at the time of her termination from employment.Loreta recounted that on August 10, 2004, she was asked to leave her office because Xu and a Feng Shui master were exploring the premises. Later that day, Xu asked Loreta to go on leave with pay for one month. She did so and returned on September 10, 2004. Upon her return, Xu and his wife asked her to resign from Wensha because, according to the Feng Shui master, her au ra did not match that of Xu. Loreta refused but was informed that she could no longer continue working at Wensha. That same afternoon, Loreta went to the NLRC and filed a case for illegal dismissal against Xu and Wensha.Labor Arbiter (LA) Francisco Robles dismissed Loreta’s complaint for lack of merit. He found it more probable that Loreta was dismissed from her employment due to Wensha’s loss of trust and confidence in her. NLRC affirmed in its Resolution,9 citing its observation that Wensha was still considering the proper action to take on the day Loreta left Wensha and filed her complaint. CA reversed the ruling of the NLRC on the ground that it gravely abused its discretion in appreciating the factual bases that led to Loreta’s dismissal. The CA noted that there were irregularities and inconsistencies in Wensha’s position.Issue: Whether or not petitioner Xu Zhi Jie is solidarily liable with Wensha. Ruling: Loreta’s security of tenure is guaran teed by the Constitution and the Labor Code. Under the security of tenure guarantee, a worker can only be terminated from his employment for cause and after due process. The records are bereft of evidence that Loreta was duly informed of the charges against her and that she was given the opportunity to respond to those charges prior to her dismissal. If there were indeed charges against Loreta that Wensha had to investigate, then it should have informed her of those charges and required her to explain her side.Wensha should also have kept records of the investigation conducted while Loreta was on leave. The law requires that two notices be given to an employee prior to a valid termination: the first notice is to inform the employee of the charges against her with a warning that she may be terminated from her employment and giving her reasonable opportunity within which to explain her side, and the second notice is the notice to the employee that upon due consideration of all the cir cumstances, she is being terminated from her employment. This is a requirement of due process and clearly, Loreta did not receive any of those required notices.Nevertheless, the Court finds merit in the argument of petitioner Xu that the CA erred in ruling that he is solidarily liable with Wensha. Elementary is the rule that a corporation is invested by law with a personality separate and distinct from those of the persons composing it and from that of any other legal entity to which it may be related. â€Å"Mere ownership by a single stockholder or by another corporation of all or nearly all of the capital stock of a corporation is not of itself sufficient ground for disregarding the separate corporate personality. In labor cases, corporate directors and officers may be held solidarily liable with the corporation for the termination of employment only if done with malice or in bad faith. Bad faith does not connote bad judgment or negligence; it imports a dishonest purpose or some moral obliquity and conscious doing of wrong; it means breach of a known duty through some motive or interest or ill will; it partakes of the nature of fraud. In the subject decision, the CA concluded that petitioner Xu and Wensha are jointly and severally liable to Loreta.We have read the decision in its entirety but simply failed to come across any finding of bad faith or malice on the part of Xu. There is, therefore, no justification for such a ruling. To sustain such a finding, there should be an evidence on record that an officer or director acted maliciously or in bad faith in terminating the services of an employee. Moreover, the finding or indication that the dismissal was effected with malice or bad faith should be stated in the decision itself.

Gang Theory Coursework Example | Topics and Well Written Essays - 500 words

Gang Theory - Coursework Example There exist the notion of alternatives in than one may reverse his decision on grounds that those alternative methods are either unavailable or their rewards are lower than expected. With the full knowledge of the consequences may opt in taking a risk. The size of a gang may limit the probability of an individual being caught and increase the chances of benefits in that if a gang member is caught the remaining members may still reap from their actions. Farrall and Bowling (1999) attributes this to the failure of human beings to leave up to their decisions as circumstances changes over a given period. Gang crimes operate mostly on assumption that their number creates a vulnerability effect to their victims in that they use their number to intimidate and organize their actions. The vulnerability aspect encourages the gangs to operate with less worry of the likeliness of being caught (Gottschalk, 2013). Those caught in crime gangs and then released due to either completing their jail term of lack of evidence may tend to ignore the risk involved in crime (Farrall & Bowling, 1999). The fear of uncertainty is what deters a person from committing crime and once experiences the consequences involved in crime some prefer to engage in crime life. Routine based crimes are what have attributed to the continuous growth of the gang-based crimes. The social rationality is also, what determines an individual’s choice in joining a gang group. The existing social inequality from, the judicial service and the unfairness by the community in terms of revenue allocation may prompt individuals with similar grievances to from gangs and recruit a sizeable number. The social aspect at this point runs paramount to the risk assessment effect of the rational choice theory. Once a group is formed under same circumstances, they tend to bond from a long

Ethics in Financial Management Essay Example | Topics and Well Written Essays - 500 words - 1

Ethics in Financial Management - Essay Example In the article discussed in this paper we see how a person in power takes advantage of his position for personal gain. Henry M. Paulson was the Treasury secretary during the Bush Administration. He was also a major shareholder of Goldman Sachs. Mr. Paulson wanted to make it seem as if his ethical standards were implacable. He sold all his shares of Goldman Sachs and vowed not to get involved in any issues associated with the investment banking sector since he had many friends and colleagues in the industry. Getting involved in issues associated with the investment banking sector would constitute a conflict of interest ethical violation. A conflict of interest occurs when a person has a conflict between his private interest and the individual public obligations (Answers, 2009). The Treasury secretary was in the middle of the entire bailout package scandal. When the government allocated $85 million dollar of the bailout money to the American International Group (AIG), Mr. Paulson’s former employer, Goldman Sachs, received millions of dollars in debt collection from AIG as a consequence of the b ailout package deal. Even though Henry Paulson claims he did nothing wrong and that his actions were not unethical in any way because he was simply doing his job as secretary of treasury, many Wall Street experts believed Goldman Sachs received preferential treatment during the entire process. During the AIG bailout package took place Mr. Paulson spoke the CEO of Goldman Sachs over two dozen times (Morgenson & Van Natta, 2009). The amount of phone calls exceeds by a lot the conversations the governmental official had with any other Wall Street executive. Mr. Paulson claimed he received an ethics waiver. To me this waiver seems like a cheap excuse because the treasury secretary’s actions were clearly an ethical violation since his former employer was receiving preferential

Islam or Shariah Law Essay Example | Topics and Well Written Essays - 250 words

Islam or Shariah Law - Essay Example Islam or ‘shariah’ law governs under the Islamic code mentioned in the Quran and Hadiths.   It is supposed to be the legal and moral code for every Muslim, comprising of religious matters financial positions and every day issues. Since the instigate of the 21stcentury many Muslim countries including Malaysia, Indonesia morocco and Pakistan, encouraged and responded to democracy and voiced their opinions of it being a much better system to govern countries. Whether the current sociopolitical and cultural settings are compatible with the ‘shariah’ law is the main point which plagues many Muslim men and women. The difficulties faced by Muslims all over are due to the confusion over the legal systems i.e. whether to follow the Islamic mode of punishment or to follow the state; whether the correct method of trade is the Islamic way (free of credit) or to follow the commercial and state policies. There have always been debates over the judicial system whether as to give harsh punishments or let the constitution decide? The debate goes on between political leader and scholars. Some Muslimscholarsbelieve that the amalgamation of ‘shariah’ laws in the legal system of a country is the best way to actually observe the Islamiclaws. One example of this is the fact that polygamy is punishable in several countries, but allowed by Islamic law. In India cows are considered sacred but they are part of the Islamic sacrificial ritual of Eid where they are slaughtered. These are situations where a Muslim cannot act based on his religion alone and has to consider the state laws first. The reaction of â€Å"secularizingIslam† has not always been a pretty sight. Just last year the Archbishop of Canterbury   was fiercely scrutinized by the Government and the political circle, his own Church and other religions after he supported the adoption of a few ‘shariah’ laws in the British system.While some British Muslim scholars ig nored it saying it will not and does not have enough votes by the community. The main point is that most nations support secular systems which are not compatible with Islamic law. The fact that the Archbishop was so heavily criticized shows that the majority in these nations do not support any such laws either. Muslims are therefore stuck in a situation where they must choose whether they wish to conform to the state law or follow their own.

Case study question- Indentify two potential areas of growth for the Essay

Case study question- Indentify two potential areas of growth for the 'Penang' Mutiara' hotel and discuss how these changes might be implemented from an operatio - Essay Example Speed and fast response are other strengths of the Penang Mutiara. Flexibility in exploiting opportunities and employment of staff through multi skill training has created unique strengths. This has resulted in the dependability factor, which a customer in the service industry cherishes and has improved occupancy rates leading to corresponding economies of scale. (www.booksites.net). The hotel can leverage its strengths as there is adequate potential for growth with continuous improvement with reference to organizational quality and performance, focusing on customer satisfaction, through constant incremental improvements to processes including removal of unnecessary activities. (www.managementhelp.com). A service industry has to balance between strategy and operations before it can consider growth options. Since Penang Mutiara is operating as an international destination, it has to see operational management from an international perspective. (Slack: 2003). International guests in the luxury segment whether these are business or tourists seek the comfort of familiarity. Thus if they have been looked after well by a particular hotel once, they would like to continue stay in the same hotel and also recommend this to their friends and associates. Word of mouth is a powerful communication tool for luxury clientele with a strong network. This aspect can be exploited by the Penang Mutiara. Thus a customer loyalty programme is the first growth area recommended for the hotel, exploiting its customer relationship, familiarity with the loyal customers and service orientation. At present the 50 percent returnee guests show that there is adequate potential for growth in this segment may be 70- 75 percent with schemes involving loyalty bonus and also loyalty recommendations which entails that any recommendation made by a customer will gain him loyalty points for him as well as his recommended guest.

Economics Assignment, The Market for Rhodium Essay

Economics Assignment, The Market for Rhodium - Essay Example Now if the prices remained same of palladium and rhodium, the demand for rhodium might increase at higher ratio than palladium because of the difference in the prices. Due to low demand of palladium, its price was decreased by the company which increased its demand. Due to increased demand for palladium, the demand for rhodium has fallen to large extent in the auto catalyst use. Because the demand for antipollution chemical has aroused only in the auto catalyst industry while the consumption of rhodium and palladium by other industries remained same. Now when the price of rhodium has fallen there is a big difference in the demand for rhodium in auto catalyst industry as compared to other industries. As auto catalyst is the major consuming unit of antipollution chemicals so demand has fallen for rhodium particularly in it due to increase in demand for palladium. Hence the trend of demand for rhodium has fallen. In the above diagram, DD is demand curve for year 2001 with demand 557 and price 1829.79 approx. D^D^ is the demand curve for year 2000 having average price of 2025.47 and demand 809. The difference between total demand has caused the price to move also. Ans.: The demand for rhodium as compared to palladium reduces in resulting of cross price elasticity. It shows that the price of palladium has been reduced by the company to reduce the pollution in the car exhausts. The greater demand of antipollution chemicals in the society enforces the company to reduce the price of palladium in order to increase its demand as compared to rhodium. The company decreases the price of palladium which greatly affects the demand and price of rhodium. Because of decreased prices of palladium, the demand for rhodium has also decreased which ultimately causes its price to be decreased. Hence due to the decrease in the price of palladium the price for rhodium has also decreased. Subsidization of industries can play an

Effectiveness of Counterinsurgency Efforts Employed Against FARC, ELN, Research Paper

Effectiveness of Counterinsurgency Efforts Employed Against FARC, ELN, and AUC. Colombian and Peruvian Guerilla Groups - Research Paper Example For the purpose of this analysis, the research has been conducted from a range of qualitative secondary sources which have helped to shed light on the extent to which the governments of Peru and Colombia have successfully prosecuted their respective counterinsurgency wars. Secondly, the research question centers on the overall effectiveness of how these counterinsurgency struggles have been organized, implemented, and the end result of the aforementioned practices. Success is therefore easily determined based upon answering the question regarding whether the counterinsurgency efforts have been effective in either A) encouraging the insurgents to lay down their weapons and join the political process B) have resulted in a complete and total defeat of the insurgency or C) have had little effect and the insurgency is ongoing unabated. As such the research question can be answered by examining the current tactical and/or political situation posed by each of the insurgent groups that will be discussed in this paper.The case of ELN is unique for a number of reasons. First, the ELN is one of the few guerilla movements that was fought and defeated during the tumultuous battles that were ongoing within the continent between supporters of left and right at the time. Second, the ELN was unique in that it chose to work outside the framework of politics; choosing instead to espouse the Cuban revolutionaries beliefs that â€Å"first comes action – then the party†. ...

Second, the ELN was unique in that it chose to work outside the framework of politics; choosing instead to espouse the Cuban revolutionaries beliefs that â€Å"first comes action – then the party†. In this way, ELN relinquished any and all claims to legitimacy it might have claimed with respect to the political process. Further, by distancing themselves from politics in such a manner, they effectively cut themselves off from all support and aid they might have received within their own country; instead, they were forced to rely on resupply and technical/tactical support from fellow communist sympathizers (usually from nations such as

An evaluation of contemporary leadership and governance challenges Research Paper - 1

An evaluation of contemporary leadership and governance challenges among universities in Africa - Research Paper Example By identifying and evaluating the major challenges that face leaders in African universities, it is possible to provide research based solutions to these problems, which in turn will enhance effective leadership strategies as the path for development in these countries. Objectives of the study Main Objectives To evaluate the challenges that are facing the leaders in African Universities in their administrative role. To investigate poor leadership qualities within the administrative bodies of the university. Specific Objectives To identify, through data collection, the major challenges that leaders in African Universities have to confront in their day to day duties. To identify weaknesses that exist within the university leadership and governance that has contributed to the problem of poor leadership. To analyse the results of the survey in to establish the common leadership problems among the African universities. To recommend possible solutions to the problems that are threatening l eadership and governance in African Universities. ... world countries and the path to rise to international heights has become rough, making these countries remain stagnated in terms of growth and development. This has generated a lot of attention among many researchers to investigate the barriers that have kept the pace of growth in these countries slow and unyielding (Task Force on Higher Education and Society, 2000). A research by Petlane (2009) indicated that one of the major challenges in these countries is the poor leadership and governance in this country that has failed to drive the country to economic success. The findings of this research have triggered significant research to investigate the challenges that University leaders have faced in implementing development goals in the country. A recent research conducted by Kuada (2010) was meant to investigate on the knowledge gaps that exist within African leaders that have undermined the development of third world countries. The findings of this research indicate that the weakness of African leaders emanates from the shortage of development skills and knowledge that exist within them. Other researchers have identified the need shortage of technological knowledge among the leaders which is a necessity in a technologically growing environment. Previous research by Hall and Symes (2005) provided that the only way to enhance development in African countries is by maintaining effective leadership in tertiary institutions and impacting leadership mentorship in upcoming professionals. Although researchers have reached a concession that the reason why African countries have failed to shine in the global scope is because of the many challenges that confront leaders in these countries, researchers have failed to identify the specific challenges that face leaders especially
