Network security threats Essay

The purpose of this memo is to let you know the importance of network security. Here I will discuss the network security threats, law that affects network security and processes and procedures for disaster recovery, data backup, and data restoration along with future action plans. Network security threats can be defined as any method used to try to breach the security of a network or system (Tulloch 2003). The goal of network security is to sustain and defend three critical properties of information, which are confidentiality, integrity and availability. This threats originate from variety of sources such as External and internal. External threats are structured threats from malicious individuals or organizations and unstructured threats from inexperienced attackers such as script kiddies. Internal threats are threats from disgruntled employees or contractors. Various network security threats exist. Some of the threats are Firewall and System Probing, Network File Systems (NFS) Application Attacks, Vendor Default Password Attacks, Denial of service (DoS) attacks, Social Engineering Attacks, Electronic Mail Attacks, Spoofing, Sniffing, Fragmentation and Splicing Attacks, Easy-To-Guess Password Compromise, Destructive Computer Viruses, Prefix Scanning, Trojan Horses and Reconnaissance attacks. The top three security threats to a network are discussed in below paragraphs. Disgruntled Employees This is the most common network security threat. Disgruntled employees, who are the group most familiar with their employer’s computers and applications, including knowing what actions might cause the most damage can create both mischief and sabotage on a computer System. The disgruntled current employees actually cause more damage than former employees do. According to Parmar, the common examples of computer-related employee sabotage are entering data incorrectly, changing and deleting data, destroying data or programs with logic bombs, crashing systems, holding data hostage and destroying hardware or facilities. Denial of Service (DoS) Attacks According to Tulloch (2003), DoS is a type of attack that tries to prevent legitimate users from accessing network services. In this type of threats, the attacker tries to prevent access to a system or network by several possible means. Some of these are: Flooding the network with so much traffic that traffic from legitimate clients is overwhelmed; Flooding the network with so many requests for a network service that the host providing the service cannot receive similar requests from legitimate clients; and Disrupting communications between hosts and legitimate clients by various means, including alteration of system configuration information or even physical destruction of network servers and components. (Tulloch 2003) Malicious Code and Electronic Mail Attacks. According to Parmar, malicious code refers to viruses , worms , Trojan horses , logic bombs, and software (uninvited). Electronic e-mail attacks are emails that hackers send to compromise network systems and whenever companies accept this e-mail from the Internet that have exposed versions of the sendmail program are potential targets from this attack. NETWORK SECURITY LAWS As such, no network security laws exist for network security. However, some of the acts that are applicable for network security threats are discussed in below paragraphs. Privacy Act of 1974 The concept of information privacy has been one of the most critical issues. It takes into serious consideration. Imagine a world without information privacy. The lack of information privacy creates a breeding ground for technological sharing and distribution. In 1974, the Privacy Act of 1974, passed by the Unites States Congress, states that: No agency shall disclose any record, which is contained in a system of records by any means of communication to any person, or to another agency, except pursuant to a written request by, or with the prior written consent of, the individual to whom the record pertains (â€Å"Privacy Act of 1974† 88 Stat. 1897). CFAA – Computer Fraud and Abuse Act. According to Robinson (2003), the current United States law of information security is the Computer Fraud and Abuse Act (18 U. S. C). It was originally enacted solely as a computer crime statute, but in its present form, it imposes both civil and criminal liability for a wide variety of acts that compromise the security of public and private sector computer systems. DMCA – The Digital Millennium Copyright Act The Digital Millennium Copyright Act (17 U. S. C), provides that â€Å"no person shall circumvent a technological measure that effectively controls access to a work protected under this title [the Copyright Law]†. (Robinson, 2003) There are other laws (acts), such as the Wiretap Act, the Stored Communications Act, and the Computer Security Act are also applicable on network security threats. PROCESS AND PROCEDURES FOR NETWORK SECURITY The three important techniques used by companies to protect their network are firewalls, encryption and VPN, which are discussed below: Firewalls Firewalls are used to control access between networks. It separate intranets and xtranets from the Internet so that only employees and authorized business partners can access. Firewalls are implemented by Packet filtering to block â€Å"illegal† traffic, which is defined by the security policy or by using a proxy server, which acts as an intermediary. Encryption To protect against sniffing, messages can be encrypted before being sent (over the Internet). In general, two classes of encryption methods Secret Key encryption (DES) and Public Key encryption (RSA, public and private key are needed) are used today. Public Key encryption is incorporated into all major Web browsers and is the basis for secure socket layer (SSL). Virtual Private Networks (VPN) VPN maintains data security as it is transmitted by using tunneling and encryption. Tunneling creates a temporary connection between a remote computer and the local network. Tunneling blocks access to anyone trying to intercept messages sent over that link. Encryption scrambles the message before it is sent and decodes it at the receiving end. Another important area for companies are (implementing) Security policy, Disaster Recovery and Business Continuity (plans), which are discussed in below paragraphs: Security policy Security policy is defined as rules, directives and practices that govern how asset, including sensitive information are managed protected and distributed within an organization. Every organization should define and document a security policy that defines the limits of acceptable behavior and how the organization will respond to violation of such behavior. Security policy defined should be concise, to the point, easy to understand and widely publicized in the organization. The security policy implemented should ensure compliance with all laws. The security policy should be reviewed periodically to respond to changes in technology or circumstances. There should be restrictions on playing of computer games on corporate computers and visiting of non-productive web sites using corporate network. In addition, employees should be monitored for prohibition against taking copies of certain corporate electronic document out of office, use of pirated software and use of corporate e-mail account for sending the personal e-mail. Proper Documentation for Disaster Recovery and Business Continuity There are various types of vulnerabilities associated with computer-based information systems. Now these days’ organizations are being more dependent upon their computer systems, therefore the survival of business depend very much on the security of these systems. Initially (few years back), physical disasters such as floods a hurricane, and fires were the most probable security risks. Nowadays, computer operations are also liable to loss or damage from hackers, computer viruses, industrial spies and similar causes which until recently were in the realms of science fiction. The terrorist attacks on September 11, 2001, showed that there is a big difference between disaster recovery and business continuity. In the past, disaster recovery meant getting computers and networks up and running after a hurricane, flood, fire, or other disaster. However, September 11 taught a broader issue getting the business up-and-running. According to McNurlin & Sprague (2006), Business continuity broadens the discussion to include: Safeguarding people during a disaster; Documenting business procedures so that not dependent upon a single employee; Giving employees the tools and space to handle personal issues first so that they can then concentrate on work; Alternate workspace for people and Backup IT sites not too close but not too far away; Up to date evacuation plans that everyone knows and has practiced; Backed up laptops and departmental servers; and Helping people cope with a disaster by having easily accessible phone lists, e-mail lists, instant-messenger lists so people can communicate with loved ones and colleagues. CONCLUSIONS The goal of network security is to sustain and defend three critical properties of information, which are confidentiality, integrity and availability. The most common threats to network security comes from disgruntled employees, DoS attacks and malicious code attacks. All these threats try to breach the security of a network or system. Various information security and privacy laws exist, which must be followed by companies while installing and managing their computer network. Various techniques such as firewalls, encryption and VPN are used for securing network. In addition, security polices and disaster recovery and business continuity plan are implemented for securing network. FUTURE ACTION Below are some methods for securing network from the top three security threats to a network. Disgruntled employees type of threats can be limited by invalidating passwords and deleting system accounts in a timely manner by network (system) administrator. According to Tulloch (2003), defenses against DoS attacks can be done by disabling unneeded network services to limit the attack surface of companies network ; enabling disk quotas for all accounts including those used by network services; implementing filtering on routers and patch operating systems to reduce exposure to SYN flooding ; base-lining normal network usage to help identify such attacks in order to quickly defeat them ; and regularly backing up system configuration information and ensuring strong password policies. To prevent malicious code attacks from occurring, regular check with vendors to ensure systems are running a correct version of sendmail or some more secure mail product are necessary. Network Security through Software and Hardware can be implemented by: †¢ Modular and cheaper workgroup firewalls. †¢ By having host based and network based Intrusion detection systems †¢ Active security by providing auto mated responses to agents. †¢ Centralized management †¢ Content filtering †¢ Acceptance of PKI †¢ By having token, smartcard or biometric based access solutions. Some basic protecting tips for computer (in network) that should be provided to all the staffs in the organization are: †¢ Always use Anti-virus Software †¢ Download security updates and patches regularly and update computer systems. †¢ Do not check or download emails and attachments from unknown sources: †¢ Back Up your data regularly. †¢ Use Firewall †¢ Do not share access to your computer hard drives in network Attachments.

Emergent Properties Essay

Emergent Properties Emergent properties are properties that come about when smaller components combine together to form a large unit that works together for a common purpose. The idea of emergent properties is based on the fact that the whole combined unit is more efficient than the sum of all of the units. These properties cannot be seen when the organisms are separated from one another, the organisms must be together for the properties to take effect. Emergent properties have come about for the fact that when combined, these organisms can perform much more complex and advanced tasks that the organisms would not be able to complete on their own. In nature we see many emergent properties arise from evolution. When birds branched off from reptiles during their evolution, they developed feathers instead of scales. These feathers do not enable flight on their own, however when combined to form a wing they become much more efficient. When these two wings come together to form a pair of wings the result is an extremely efficient form of transportation that is not only light but also water resistant. Another example of emergent properties would be evident in our brain. Which each brain cell does not possess much computing power, however when billions of them are combined together, the result is a very efficient computing unit that can provide us with such things as thoughts emotions and character. Each brain cell alone would not be able to do these things. Emergent properties exist all around us and we even display some of these properties. One example of emergent properties would be the collaboration of many human beings. Separated, our minds are powerful, but nearly limited. Once combined we can collaborate with each other and perform many tasks efficiently, such as running a county, for example. It is not a coincidence that dictatorships are notoriously unsuccessful. There are also many emergent properties that exist beyond living things. For example when you have a hurricane, essentially all you have is air and water at various different temperatures. The randomness of this collection of air produces a large air mass that has a specific circular motion which is very powerful and devastating to anything that comes into contact with it. The air itself and the water vapor would not be able to cause this force on their own. It is the random order that makes this hurricane so powerful and hard to predict. Another example of emergence away from biology is currency. Currency or money came about as people wanted to trade with one another, but had no medium to do so. Alone, a single person would not need money. It is only useful and evident as many people come together to form a group. Without this group the money would have no value because it’s value is determined by people who are willing to trade with it. In conclusion emergence is evident throughout nature and even past it. It is the way  complex systems  and patterns arise out of a  multiplicity  of relatively simple interactions. Emergence is central to the understanding of communities and ecosystems where it be in living organisms or beyond biology.

Sociological Perpestives in Health and Social Care

In this assignment I am going to write a report explaining the patterns and trends of health and illness in three social groups: gender, ethnicity and social class. I am also going to explain the pattern and trends of health and illness which looks at measurement of health, morbidity rates, mortality rates, disease incidence, disease prevalence and health surveillance. Measurements of health Health is generally measured in negative terms, such as the level of disease and the number of deaths within a population, rather than by analysis of positive indicators, such as the presence of health.Epidemiology is the study of disease origins or cause and how much information about the number of people within a population. Epidemiological data provides valuable information about the number of people a population that are affected by ill health, who die as a result of particular health problems and which groups of individuals are most at risk of developing and dying from particular types of il lness or disease. This information is used to identify and plan appropriate health and social care services as well as health-promotion activities.The most commonly used indicators are morbidity (presence of illness or disease) and mortality (death). (Eleanor Landridge, 2007) Morbidity rates Morbidity is difficult to measure as the information is gathered from a range of different sources. Data is collected by the government as well as the NHS and local authority social services departments through direct surveys of the population such as specific health surveys, and as a result of administrative processes, for example, when an individual visits a GP or A&E department or has an assessment of needs.Some diseases are required to be reported, for example cancers and infectious diseases and so data is collected via this process. The problem with this information is that to some extent it reflects services that are available rather than the true picture of disease incidence. Individuals have to also express their needs through actively seeking medical or social care services. (Eleanor Landridge, 2007) The general household survey is a continuous government population survey this includes questions about peoples experience of llness both acute and chronic within the two weeks prior to the person completing the survey. The individual GHS 2002 interview includes questions regarding health and the use of health services; this provides information about the individual’s view of their health. The measurement of working days lost due to sickness can also provide a measure of morbidity for those who are in paid employment. As a measure, it is limited as it only relates to paid employment and this excludes many women who are at home caring for children or older people as well as those who are retired and unable to work through disability. Eleanor Landridge, 2007) Mortality rates The Office for national statistics is responsible for collecting and analysing data colle cted from a range of sources including the ten year national population census, the GHS and specific health information gathered through, for example, deaths and disease incidence reporting undertaken by GP’s and strategic health authorities. Mortality rates can be compared internationally because most countries hold similar information. Mortality rate are expressed in several different ways.A basis measurement is to express mortality as a number of deaths per 100 per year. However this does not allow the diversity of age within the population which varies over time and between geographical areas. For example, mortality rates in the south-east of England will appear high as there are a high percentage of older people living there. The standardised mortality ration (SMR) is the method used to compare mortality levels across different years or for different sub-populations within the same year.The SMR is useful because it can be used to identify and for comparisons. Infant mort ality rate (IMR) are also used as a measurement of health as this provides information about the number of deaths that occur in the first year of life per 1000 live births per year. The IMR is strongly associated with adult mortality rates as it is sensitive to changes in preventive medicine and improvements in health services. Gender, age, social class and cause of death are variables that can be assessed through analysis of the mortality rates. Eleanor Landridge, 2007) Disease incidence & prevalence Within epidemiology the term ‘disease incidence’ is the proportion of a group that is free of a condition but who develop it over a given period of time, such as a day, week, month, year or decade. It measures the number of new cases that occur in the population. The incidence of a disease will depends on the cause of the disease, for example, why it occurs.There might be an infectious agent which requires certain conditions for transmission, or it may be that the disease occurs due to some genetic factor, with or without certain predisposing environmental conditions. The prevalence of a disease depends not only on the incidence (how often new cases occur in a particular group of people), but also on the course of the disease, whether it can be treated, how long it would last and if people can die as a result of it.Prevalence studies therefore provide a snapshot of how many people in the given population have the specific disease being measured at a given point in time. Disease incidence and prevalence are related but measure different aspects of disease within the population. (Kelly Davis, 2010) Health surveillance Health surveillance is generally related to occupational health screening methods used to identify occupational health hazards for workers. The description has been widened to include the range of routine health screening strategies and methods which begin before birth and throughout an individuals life.Health surveillance is increasingly available, such as screening for specific cancers (breast, cervical, prostate), diabetes, high blood pressure, raised blood cholesterol levels and bone density. All of these are aimed at early detection of treatable conditions and may be targeted at specific ‘at risk’ groups within the population. In this course of carrying out this surveillance, information about the incidence and prevalence will be gathered as many of these treatable conditions may be without symptoms and so not alert the individual to the presence of a problem. Kelly Davis, 2010) 158,900 males and 156,300 females were newly diagnosed with cancer each year in the UK during 2007–09, equivalent to incidence rates of 427 per 100,000 males and 371 per 100,000 females Around 81,600 males and 74,600 females died from cancer in each of those years in the UK, corresponding to mortality rates of 209 per 100,000 males and 151 per 100,000 females Breast cancer had the highest incidence rate in females (1 24 cases per 100,000 females) and prostate cancer had the highest incidence rate for males (103 cases per 100,000 males) ttp://www. ons. gov. uk/ons/rel/cancer-unit/cancer-incidence-and-mortality/2007-2009/stb-cancer-incidence-and-mortality. html The Black report was a document published in 1980 by the Department of Health and Social Security in the United Kingdom, which was the report of the expert committee into health inequality chaired by Sir Douglas Black. It was demonstrated that although overall health had improved since the introduction of the welfare state, there were widespread health inequalities.It also found that the main cause of these inequalities was economic inequality. The result of the black report stated that risk on death increase with lower social classes. People in lower class were more likely to suffer from respiratory disease. Babies that were born to parents in social class V had a higher chance of death in the first month compared with babies of profession al class parents.The report showed that there had continued to be an improvement in health across all the classes, during the first 35 years of the National Health Service but there was still a co-relation between social class, and infant mortality rates, life expectancy and inequalities in the use of medical services The introduction of the NHS intended to present everyone with free healthcare despite of their income and social class status. The general household survey showed that patterns of morbidity were followed to a related class gradient to that of mortality.This showed that people in lower socioeconomic groups reported ill health more compared to those in higher socioeconomic groups. In addition the black report found that working class people did not use health care services often which resulted to them not receiving the care that they required, whereas middle class people used health services frequently and had better care compared to working class people (Jennie Nadioo/J ane Wills/2001) http://sonet. nottingham. ac. uk/rlos/ucel/blackinequalities/Default. html Ethnicity People from minority ethnic groups were found to self-report poor health more frequently and visit their GP more frequently.People from south Asia especially Bangladeshi and Pakistani origins have moderately higher incidence of coronary heart disease and poorer health than other ethnic groups as shown in the graph. There is also a higher prevalence of diagnosed non-insulin dependent diabetes among south Asians and people from the Caribbean, with mortality directly associated with diabetes amongst south Asia migrants around three and a half times that of the general population. Ethnicity refers to: culture, religion, language and history which are all shared by groups of people and are passed on generation by generation.Ethnicity can carry along barriers that can affect health, for example language barrier. People may find it hard to communicate and may find it difficult to explain ho w they are feeling if they are suffering from ill health, this may lead to illness and disease spreading and causing long term health problems. Language and cultural barriers can have major effect on someone’s live, as they will not be able to make full use of health care services. For example Asian women are sometime dependent to seek medical advice from male doctors or they may have problems in speaking English.Some people may be unwilling to seek medical advices as they have suffered from racism or the fear of racism is worrying to them. Diet can bring along factors that can cause health problems. For example someone people may eat food that is high in fat and cholesterol this can lead to ill health if safety measures are not taken. Lifestyle can also cause ill health for example leading an unhealthy lifestyle and not exercising can cause obesity which can lead to a number of illnesses such as coronary heart disease and diabetes. (Eleanor Landridge, 2007) – (Kelly D avis 2010) Social classEven though official statistics must be treated with care, there is overpowering evidence that health and ill-health and life expectancy vary according to social group and especially according to social class. People from higher social class are living longer and enjoying better health than the people from lower social class. (Kelly Davis/2010) The black report was mainly based around social class that middle class and upper class people have better standards of living, quality of life and health than working class and lower class people, as shown in the graph, people from lower class suffer from more illnesses than those in higher class.Today life expectancy at birth remains lower for those in the lower social classes than in the professional classes. Nearly every kind of illness is linked to class. Poverty is the major driver of ill health, and poorer people tend to get sick more often, to be ill for longer and to die younger than richer people. Those who di e younger are people who live on benefits or low wages, who work in unhealthy work places, live in poor workplaces, who live in poor quality housing, and who eat unhealthy food.In modern Britain, lung cancer and stomach cancer occur twice as often among men in manual jobs as among men in professional jobs, and death rates from heart disease and lung cancer, the two biggest causes of premature death, about twice as high for those from manual backgrounds. (Eleanor Landridge, 2007) Gender Gender is also a factor that can affect health. Men and women have different patterns of ill health but males have a higher rate of illnesses. This can be because men and women are expected to have roles which they adapt from society and because of this males are less likely to access routine screening.However women are seen as the carer of the family therefore is able to access them and other health care services. Because of this potential illnesses in women can be identified earlier. As shown in the graph women suffer from more illnesses then men do. Women are more likely to report physical and physiological problems to their GP so the studies that show that women get ill more often then men may not be accurate. The main reason women may be hospitalised is due to pregnancies, child birth, contraception, menopause and menstruation.They also constitute the majority of people suffering from neurosis. Psychosis, dementia and depressive disorders. Because women have higher life expectancy than men they are more likely to use health services longer/ more than me. Even if women do have higher morbidity rates then men or not they are more likely to suffer from cancer, arthritis and rheumatism then men, where as men are more likely to suffer from circulatory diseases and strokes. Life expectancy has gone up for both men and women in the last hundred years but has increased more for women.The main cause of death among men is heart disease, lung cancer, bronchitis, accidents and other vi olent deaths. For women the main causes of death are breast cancer, cervix cancer and uterus cancer also coronary heart disease. Although smoking prevalence has declined dramatically during the past ofur decades, men are still more likely to smoke then women across all ages. In 1974, 51% of men and 41% of women smoked whereas in 2007 these figures have dropped to 22% and 20% respectively. (office of national statistics 2006a, 2009) (Eleanor Landridge, 2007) – (Kelly Davis 2010)

King oedipus analysis Essay

Destiny and Freewill   This is one of the most important themes in the play and leaves the reader with the engrossing question of whether or not freewill is an illusion. The play doesn’t actually answer this question, but it shows the complex interplay of fate and freewill that culminates in Oedipus’ tragic plight. Jocasta, Laius and Oedipus all try to escape the prophecy but they are unwittingly led into their seemingly unavoidable fate. This element of the play is intended to show the reader the power of prophecy and the supreme authority of the gods in contrast with the futility of human beings. The play also shows how human nature plays a vital role in the fulfilment of the prophecy. Compassion and pity on the shepherd’s behalf prevents Oedipus from dying as a baby. Oedipus’ own impetuous temper results in the murder of his own father, Laius. His momentary display of intelligence in solving the riddle is his ultimate triumph as well as his seed of destruction as it results in marriage to his mother, Jocasta. In resolving to find out the truth about his birth, he brings the suffering on himself. His arrogant, taunting attitude towards Teirisias further exposes the terrible truth. In this way, the play shows how freewill also contributes to Oedipus’ downfall. Pride and humility   Pride is Oedipus’ fatal flaw; his arrogance towards both the gods and human beings leads to his destruction. Sophocles probably intended to teach people the importance of humility and recognising the superiority of the gods that they believed in. Oedipus’ arrogance is displayed in his long, speeches and in the hot-headed way he unknowingly killed his father. His initial refusal to accept any blame or wrongdoing on his part shows that he has a high opinion of himself. One of the main sources of his pride is his defeat of the Sphinx, which saved Thebes and put him on the throne, and yet the reader knows that this was also the cause of one of his foulest crimes, marriage to his mother. In this way, the playwright communicates a message about the folly of taking human achievement too seriously. Because of this, the play is not very humanistic but belittles human beings as futile and flawed. Wisdom and ignorance The conflict between Teirisias and Oedipus represents the conflict between wisdom and ignorance, Teirisias being wisdom and Oedipus being ignorance. Teirisias’ comment â€Å"To be wise is to suffer† is ironic because it comes true for Oedipus. When he learns the truth about himself and becomes wise, he is in utmost agony. The play shows that perhaps having knowledge is not necessarily a good thing, as Teirisias warns, and that there are limitations to our knowledge that we should accept. Sight and blindness   Teirisia is a blind seer, which sounds like a contradiction in terms. However, even though he is physically blind, he has the insight and knowledge, which Oedipus lacks. When Oedipus finally gains this insight at the end of the play, he blinds himself physically. Throughout the play, Oedipus is blinded by his own arrogance, shown in his refusal to accept that he is the cause of Thebes’ misery. â€Å"Living in perpetual night, you cannot harm me, or any man else that sees the light. †   His deliberate disbelief enables him to issue the curse, never considering that it might affect himself in the end. Oedipus is also blind to his true position in relation to the gods. He believes he can thwart prophecy and outsmart the gods. The attitude he displays shows that he has almost made himself a god, who has the power to curse and demand whatever knowledge he seeks. Humility   Sophocles certainly agrees with this contention in his play, King Oedipus. The character of Creon who is more cautious is intended to contrast with Oedipus’ impetuous arrogance. It is Oedipus’ lack of humility that causes much of his own suffering. On the other hand, Creon’s more careful approach to life evades a potentially disastrous situation when Oedipus accuses him of conspiracy. Characters Oedipus   Oedipus is willing to help the people of Thebes. â€Å"I would gladly do anything to help you. † He is actively involved with his city. â€Å"I have not thought it fit to rely on my messengers, but am here to learn for myself†¦ †   Arrogant – proud of his own abilities such as solving the riddle of the sphinx. â€Å"Until I came – I, ignorant Oedipus, came – and stopped the riddler’s mouth, guessing the truth by mother-wit, not bird-lore. † Sympathetic towards the city of Thebes – â€Å"I grieve for you my children. Believe me, I know all that you desire of me, all that you suffer; and while you suffer none suffers more than I. †   Jumps to conclusions about the ones closest to him. He accuses Creon of conspiring to take over the throne. â€Å"Must Creon, so long my friend, my most trusted friend, stalk me by stealth and study to dispossess me of the power that this city has given to me†¦ † He assumes that Jocasta fears that he was an illegitimate child. â€Å"The woman, with more than woman’s pride, is shamed by my low origin. †   Easily angered, irascible especially by Teiresias – â€Å"Insolent scoundrel†¦ Shameless and brainless, sightless, senseless sot! †   Steadfast and staunch in his quest to expose the truth. â€Å"Nonsense: I must pursue this trail to the end, till I have unravelled the mystery of my birth. † Not a fatalist; expresses the belief that ‘chance rules our lives’.   Acts as the mediator between Oedipus and Creon, typical of her role as a mother and wife. â€Å"What is the meaning of this loud argument, you quarrelsome men?†¦ You are making much of some unimportant grievance. †   Abandons Oedipus on the hillside to perish because of prophecy yet dismisses prophecy later in the play. â€Å"For I can tell you, no man possesses the secret of divination. And I have proof†¦ Why should you then, heed them for a moment? † and â€Å"A fig for divination! †   Cannot face the horror of the truth and dies at her own hands Creon   A contrast to Oedipus in terms of character. He is calmer and more reasonable. â€Å"Reason with yourself, as I; and ask, would any man exchange a quiet life, with royal rank assured, for an uneasy throne? † He is more humble and cautious- â€Å"I do not presume to say more than I know†, and acknowledges the gods – â€Å"God will decide, not I. † He is deeply hurt by Oedipus’ accusations – â€Å"If he thinks that I have done him any harm, by word or act, in this calamitous hour, I will not live†¦ † Teiresias   Physically blind, yet gifted with second sight (prophecy). â€Å"All heavenly and earthly knowledge are in your grasp. In your heart, if not with eye, you see our city’s condition. † Reluctant to share his knowledge with Oedipus because he knows the damage it will cause. â€Å"When wisdom brings no profit, to be wise is to suffer. † Laius   He is only mentioned through other people in the play. Shepherd   Like Teiresias to impart his knowledge until threatened. Oedipus terrorizes, â€Å"Answer! If I must speak again, you die! † He also serves to confirm Oedipus’ greatest fears. Chorus Represents the voice of the elders as well as the general public. It comments on the action in the play, sometimes siding with Oedipus, other times questioning his actions and words. They are the voice of religious belief, more than once urging the need to heed the words of the gods. â€Å"I only ask to live, with pure faith keeping in word and deed that Law which leaps the sky, made of no mortal mould†¦ whose living godhead does not age or die. † It is at times philosophical, commenting on the nature of existence and the frailty of human attainment and success. â€Å"All the generations of mortal man add up to nothing! Show me the man whose happiness was anything more than an illusion followed by disillusion. Here is the instance, here is Oedipus, here is the reason why I will call no mortal creature happy†¦ Then learn that mortal man must always look to his ending. And none can be called happy until that day when he carries his happiness down to the grave in peace. † Symbols Sight and blindness – this is used as a metaphor for knowledge and ignorance. Context   The play was written during the Classical period in Ancient Greece in the 5th century BC, a time of optimistic humanism. Sophocles tends to celebrate humanity but also plea for adherence to justice, moderation and the gods.

Fashion Media and Communication - Essay Example The essay "Fashion Media and Communication" explores the media and communication in fashion. Essentially, for my investigation, I’ve decided to focus on the dazed vision described as the â€Å"in house video arms†. Notably, dazed vision came to being in December 2012. Most notably, the Vise Media; a globally recognized digital media; acquired the British style bible i-D. It is worth noting that this move took the online world by storm and established a new experience in the digital communication through video-driven experiences. Apparently, this innovation was brought about to counter the changes experienced in the young fashion industry. In addition to that, the fashion industry has been crowded with more than enough outdated media used in communicating with the consumers. Notably, the new launches thus demonstrate how the media landscape is radically reshaped each day by the dynamics of the internet. Furthermore, these dynamics have modified the content and how it is being advertised to the targeted consumers.It is important to note that the industry, especially the fashion industry, have to change their ways of staying competitive in the market. On the same point, this competition has therefore brought about innovation in a manner that the most innovative company attracts both the investors and the large base of customers. On the contrary, there are several important factors that can be used to give a detailed definition of the dazed vision, namely. Statistical evidence shows that by the year 2017.

Non compliance in doing homework assignments between group therapy Dissertation

Non compliance in doing homework assignments between group therapy sessions for substance abuse and depression - Dissertation Example Ries et al. (2009, p.762) state that patients with substance abuse who comply with the group therapy sessions and complete their homework assignments experience positive treatment outcomes and thus are less likely to drop out of the treatment. They state that â€Å"integrated supportive group therapy in a randomized trial has shown a differential effect on treatment retention in subjects with severe mental disorders and substance use disorders†, and homework compliance is the adherence that comes as one positive outcome of group therapy sessions for such patients. Reinecke (2010, p.54) maintains the idea that clients with depression are less likely to adhere with the â€Å"in-session exposure† which makes them non-comply with homework completion. He states that the cause for this is that the in-session exposure of a depressive client or one suffering from anxiety involves others observing him doing homework, which he is already anxious about, thus enhancing his anxiety into social anxiety disorder. However, Reinecke affirms that homework compliance is an important bridge between the in-session activities and change of client’s attitude toward life, especially for patients with depression, anxiety and substance abuse. He suggests that the client’s behavior of homework non-compliance should be addressed very early in the therapy. Cruess et al. (2010) found that the patients reported that they non-comply with the between-session homework because of â€Å"lack of receptivity to details regarding their medical illness†. Lien et al. (2010) studied in their research the relationship between the substance abuse group therapy sessions and patient compliance. They found that what motivates the patients to comply with the completion of between-session homework is the clinical outcome which they want to see as their health benefits. According to them, â€Å"patients balance expected benefits and costs during a treatment episode when deci ding on compliance† and hence comply with the standards if they seem to be benefitting from the treatment since the Lien et al. observed that those patients who were progressing were less likely to not complete homework, not show at or drop out of the sessions. Similar conclusions have been approached by Guardiano, Weinstock and Miller (2011) who have found that patients of substance abuse are at high risk of non-compliance with homework completion or attendance at group therapy sessions due to which they have to suffer from negative consequences. They have proposed an adjunctive psychosocial intervention that will reduce noncompliance in substance abusers. According to them, â€Å"The intervention involves brief in-person sessions and follow-up phone contacts with the patient and a significant other/family member.† They state that this intervention will improve the effects of group therapy on substance abusers by helping enhance the relationship between them and the pr ovider thus motivating them to attend the group therapy sessions while adhering to the homework completion. Abramowitz et al. (2009, p.104) have suggested that patients can be motivated to comply with homework completion in group therapy sessions by encouraging â€Å"self-controlled exposure† so that patients are motivated â€Å"to perform more exposure exercises†. Mausbach et al. (2010) studied relationship between depressive clients’ homework compliance and group therapy outcomes and found

CAMPBELL KEYBOARD CORPORATION Essay Example | Topics and Well Written Essays - 750 words

CAMPBELL KEYBOARD CORPORATION - Essay Example As a result of the nature of the order, Ingborg proposed two options for the quotation. The first quotation was to be based on the worth of the entire job which Plum Computer was willing and able to pay Campbell Keyboard. This proposal would therefore be in principal, a fraction of the payment made to Campbell Keyboard. Consequently, Smith had to disclose the value of the job to Ingborg so as to come up with a quotation price for the RF transmitter. In my opinion, this proposal meant that Smith would disclose vital information by revealing the worth of the job. By so doing, Ingborg would have tied the cost of the RF transmitter to the whole value thereby attaining a higher price. Attaching the cost of the RF transmitter to the value of the whole job would not be realistic as the transmitter is being purchased by Campbell Keyboard, thus Ingborg should not be concerned with the contract in place between Campbell Keyboard and Plum Computer. Smith should therefore not agree to this propo sal since it not only reveals information on a contract with a client but it is also an expensive option due to it being a percentage of the entire value of the job. The second proposal from Ingborg was for $33 per hour straight time and $40 for overtime based on the actual hours spent on the job. This proposal is more realistic as the cost is based on the amount of hours that Ingborg put in the production of the RF transmitter. In my opinion, this is the best proposal of the two not only because the cost is based on the work done but also because it would be cheaper than the first proposal in the long run. This option is also better for negotiating on the side of Smith since the cost per hour can be negotiated lower than is stated by Ingborg. Although it would be difficult to ascertain the exact hours worked by Ingborg, Smith has more leverage in this proposal than the previous one. Are there any other choices open to Smith for arriving at an equitable agreement? Smith can research on the market charges by the other firms and use the average as a basis for negotiating. The market prices for the three other sources could be essential to coming to an agreement. Even though the three other companies were not in a position to handle the order due to time constraints, Smith can still get the cost they would charge on making the RF transmitter and use the average during the negotiation with Ingborg. By so doing, Ingborg would realize that Smith has knowledge on the on goings in the market thus giving Smith a bit of leverage during negotiations. Another option available to Smith is giving a counter proposal that is based on the cost of producing the RF transmitter that Campbell Keyboard has incurred in the past. Campbell Keyboard also produces RF transmitters but due to the time limitations in place for this new order, it is difficult to manufacture hence the need to outsource the product. Therefore, in order to come to an equitable agreement, Smith can use the cost of manufacturing the RF transmitter that Campbell Keyboard has incurred in the past and use it as a basis for negotiating with Ingborg. By doing this, a relatively fair price can achieved on the side of Campbell Keyboard and an equitable agreement can be arrived at. How would you have handled the procurement if you were Smith? If I were Smith, I would invite proposals from companies who could make the RF transmitter within the time frame and specifications needed, to bid for
