1. Introduction: Detailed design starts after the system phase and system has been certified through the review. The goal of this phase is to develop internal logic of each of the modules identified during system design In the system design, the focus is an identifying the modules, whereas during the detailed design the focus is on designing the logic for the modules. In other words in system design attention is on what components are needed, while in the detailed design how the component can be implemented in the software is the issue. The design process for software system has two events. At the first level focus is on deciding which modules are needed for the system, the specification of these modules and how the modules should be interconnected. This is called system design or top level design. In the specification of the module can be satisfied is decided. This design level is often called detailed design or logic design, because the detailed design is extension of system design, system design controls the major structural characteristics of the system. The system design has a major impact testability and modifiability of a system and impacts its efficiency much of the design efforts for the designing software are spent creating the system design. 2. Applicable documents: The detailed design refers the system documents hence the first application documents here is system design, also we are referring the data structure. Hence second application document here is database design 3. Structure of software package: The software package consists of following functional components. * Functional component 1: Registration. * Functional component 2: Book issue. * Functional component 3: Book return. * Functional component 4: Search/view book details. * Functional component 5: Update book details. * Functional component 6: Payment (Fine). 3.1 Structure charts: It is graphics representation of the control logic of processing function or module representation of the system. It is one of the most common methods used for system design. In a structure charts each program module is represented by a rectangle box, modules at the top level of the structure charts call the modules at the lower level. The connection between modular are represented by lines between the rectangular boxes. The connection describes the data flows between the called and calling modules. 4. Module Decomposition: 4.1 Student details: In this form the users have to enter the details about the student like name, regno, course†¦etc. If the proper details are not entered at the same time error message will be displayed and record will not be stored†¦And if the entered register number is already exist then the details can’t be stored and error message will be displayed. 4.2 Delete student details: In this case admin can delete individual student details by entering his register number .If the Register no is not entered at same time message will be displayed and record will not be stored†¦And if the entered number is already deleted then it will be giving the message. 4.3 Book issue: In this form the Liberian can issue the books to the student. If the books are already distributed to students then Liberian can’t issue those particular books. 4.4 Book return: Here the user must return the book on given date†¦ Otherwise fine will be calculated†¦ 4.5 Calculate fine: In this case we can maintain the late fine of library member who return the issued book after the due date†¦

Importance of Couseling Essay

The study was limited to only sixteen secondary schools: thirteen government secondary schools and three mission secondary schools in Benin City with practicing school counsellor(s). In all, there were four hundred and twenty respondents (420). Sex was not a factor in the study. Two four-point Likert type scale questionnaires were used to obtain data for the study. These are: Secondary School Counsellors’ Questionnaire (SSCQ); and Secondary School Students’ Questionnaire (SSSQ). The reliabilities of 0.69 and 0.80 were obtained respectively SSCQ and SSSQ using the Cronbach Alpha Internal Consistency reliability. The findings show that there are insufficient counsellors in schools; inadequate availability of counselling facilities; and that the qualification of guidance and counselling personnel has impact on the quality of guidance services they provide to secondary school students in Nigeria. These findings suggest that these variables will help to promote students’ adjustment in the school and the society at large. Paradoxically, the absence of these variables could precipitate students’ maladjustment. Recommendations on ways of improving guidance and counselling services to promote students adjustment were proffered. Keywords: Counselling Qualities; Guidance and Counselling; Students adjustment;; Nigeria 1. Introduction Guidance and Counselling happens to be one of the developments in the field of Education in Nigeria. It became popular with the introduction of the 6-3-3-4 educational system. It is generally accepted that in Nigeria, the organized/formal guidance started in 1959 at St. Theresa’s College, Oke-Ado in Ibadan by some Reverend Sisters, out of concern for the products of their school. They felt that there was need to offer vocational guidance to their outgoing final year students. As a result, the Rev. Sisters invited twenty educated people from Ibadan community who were in different professions and therefore knew more about the emerging world of work than the students and the Rev. Sisters. Fifty-four out of the sixty students benefited from the experts’ advice and were placed in various jobs. The innovation was highly accepted by the society because in later years this group of people, though not trained counsellors, organized career talks, seminars, guidance workshops and lectures for the class five students. Later on, the vocational guidance services spread to other secondary schools outside Ibadan and across the entire federation. The ministry officials became so interested in these organized services that this group of â€Å"Career Advisers† was invited to provide career workshops for teachers and career masters. Eventually the term â€Å"Career Advisers† became a national issue. In an attempt to overhaul the old educational system, towards the needs of the nation, the Nigerian Educational Research Council (NERC) in September 1969 organized a conference on curriculum development. The curriculum conference was followed by a government sponsored National Seminar in 1973 under the chairmanship of Chief S.O. Adebo to deliberate on all aspects of a National Policy on Education using the report of the 1969 curriculum conference as the working document. The conference came up with recommendations for a New National Policy on Education, which the Federal Government accepted and published in 1977 and revised in 1981, 1989 and 2004. With the highlighted changes in the Nation’s educational system, the need for guidance and counselling services in Nigerian secondary schools became more glaring. Consequently, Guidance and Counselling Services became an integral and essential component of the educational process for all students as they progress through the educational system. According to Egbochuku (2008), the aims of school guidance and counselling services, which are based on a developmental hierarchy, are to provide students with: 1. Opportunities to develop knowledge and appreciation of themselves and others; 2. Opportunities to develop relationship skills, ethical standards and a sense of responsibility; 3. Opportunities to acquire skills and attitudes necessary to develop educational goals which are suited to their needs, interests and abilities; 4. Information that would enable them to make decisions about life and career opportunities (: 15). Today, guidance and counselling has gained prominence in t he Nigerian educational system and many people are getting interested in the guidance of youth in making wise educational, vocational and personal/social decisions. Consequent upon the expansion of counselling activities in Nigeria and the need to form a larger association to embrace both counsellors and career masters, the Counselling Association of Nigeria (CAN) was launched on the 11th November 1976. To facilitate efficient management of guidance and counselling services in Nigeria secondary schools, guidance and counselling personnel are being trained in the tertiary institutions and sent to schools to deliver these services. Also, basic courses in guidance and counselling feature in all teachers-education programmes. Prominent among the services rendered by guidance and counselling personnel in secondary schools are Information, Appraisal, Referral, Guidance, Counselling and Planning, Placement and follow-up services for the proper guidance of students. Against this background therefore, the focus of the study is to assess the realities of guidance and counselling services in providing adequate guidance for Nigerian secondary school students. 1.1. Statement of the problem It is assumed that with the increasing complexities in the society, industrial and technological development all going hand-in-hand, the succeeding generation will find it difficult to adjust themselves both to the society, work, family and schools. Failures in proper adjustment to all the facets mentioned could affect the education of young people and expose them to environmental as well as personal problems in development. Guidance and Counselling, as a delivery service, should not be misconstrued as the traditional type that is based on the principles of â€Å"to guide, to direct on a course, to enlighten, or to assist†. This traditional type of counselling was principally carried out in African setting by heads of families, Priests, and church leaders (Olayinka and Omoegun, 2001). Because of the complex nature of Nigerian society, the counselling profession has assumed a wider role. Present day Guidance and counselling is based on the process of helping individuals understand themselves which will lead to the better understanding of the other aspect of their lives (Egbochuku, 2008).   According to the literature, these services are the formalized actions taken by the school to make guidance operational and available to students. These formalized actions typically consist of a set of processes, techniques and functions that serve to carry out the guidance and counselling goals of a particular educational level. For students to be properly informed, they need the assistance of trained guidance and counselling personnel. Hence, the government made it a policy that guidance and counselling should feature in teacher-education programmes because teachers are closer to the students. Furthermore, the department of Guidance and Counselling has been established in most Nigeria Universities to train counsellors at the B.Sc., Master and PhD levels, to equip them with the appropriate counselling techniques to carry out guidance and counselling services in secondary schools. There is need therefore to assess the guidance and counselling services rendered by school counsellors to find out if these services actually provide adequate guidance for students’ development. It is therefore hypothesized that Qualification of guidance and counselling personnel, availability of guidance and counselling facilities, quality of guidance and counselling services will not significantly predict students’ adjustment 1.2. Purpose of the study This study assessed the quality of guidance and counselling services in secondary schools with practicing school counsellors in Edo state. To achieve this, the researcher examined the qualification of personnel providing guidance and counselling services, availability of materials for the successful execution of Nigerian secondary school guidance and counselling services and the impact of guidance programs on students’ adjustment. 1.3. Significance of the study Guidance and counselling is the bedrock for achieving self-actualisation. It is a process of helping individuals to understand themselves by discovering their own needs, interests and capabilities in order to formulate their own goals and make plans for realizing those goals. An analysis of guidance and counselling services in providing adequate guidance for secondary school students is of paramount importance; hence the this study. The result from the study will help in throwing more light on how guidance and counselling services is being implemented in secondary schools in Nigeria and the quality of guidance services received by secondary school students. In addition, it provides information to education planners and school administrators on their responsibility in providing adequate facilities for guidance and counselling services in order for students to receive quality guidance. It also reveals the extent to which guidance and counselling services influence the total development of the potentials and proper adjustment of secondary school students. 2. Methodology This is a survey study using correlational research design. The scope of the study covers some selected government and mission secondary schools with practicing school counsellors in Benin City of Edo State Nigeria. This is because Benin City is a metropolitan city and consists of three well-populated Local Government Areas (Egor, Oredo, Ikpoba Okha LGA) in Edo –South Senatorial District, out of the 18 LGAs in the 3 Senatorial Districts of Edo State. Purposive sampling techniques and simple random sampling techniques were employed in selecting the sample for the study. This study was limited to only sixteen (16) secondary schools thirteen (13) government secondary schools and three mission secondary schools in Benin City because only these schools had practicing school counsellor(s) as at the time the study was carried out. In all, there were four hundred and twenty respondents (420). Sex was not a factor in the study. 2.1. Instrumentation Two different four-point Likert type scale questionnaires were designed by the researcher to obtain data for the study. These are: (1) Secondary School Counsellors’ Questionnaire (SSCQ); (2) Secondary School Students’ Questionnaire (SSSQ) The SSCQ consisted of two main sections viz: Section ‘A’: This consisted of three items requesting information about the level of qualification in guidance and counselling from the respondents. Section ‘B’: This consisted of five items requesting information about the availability of guidance and counselling facilitiesmaterials in the school. The SSSQ also consisted of two sections viz: Section ‘A’: This consisted of eleven items eliciting information about the quality of guidance services rend by counsellors in the school from the respondents. Section ‘B’: This consisted of twelve items requesting information about the impact of guidance and counselling services on Nigerian secondary school students’ adjustment. The respondents in each case were requested to indicate the extent to which they agreed or disagreed to each item. Items one to three in section â€Å"A† of the SSCQ and items one to eleven in section â€Å"A† of the SSSQ were used to test hypothesis one. Items one to five in section â€Å"B† of the SSCQ and items one to eleven in section â€Å"A† of the SSSQ were used to test hypothesis two. Items one to eleven in section â€Å"A† of the SSSQ and items one to twelve in section â€Å"B† of the SSSQ were used to test hypothesis three. The scoring of the instruments was as follow: Strongly Agree (SA)-4 Agree (A)-3 Disagree (D)-2 Strongly Disagree (SD)-1 For all positive worded items the above was the case, while the reverse was the case for all negative worded items in the questionnaire. 2.1.1. Validity and Reliability of the instruments Both construct and face validity was established. The reliability of 0.69 and 0.67 were obtained respectively for sections A and B of the instrument for Counsellors (SSCQ) using the Cronbach Alpha Internal Consistency reliability test. The Students’ Questionnaire (SSSQ) yielded an alpha coefficient of reliability 0.80. 2.1.2. Administration of the instruments Permission was obtained from the school before administering the questionnaires, which were personally administered by the investigator to the respondents in the various secondary schools selected for the study. 2.2. Analysis of Data Descriptive Statistics and Pearson Product Correlation were used were used for analysis. 3. Results Variables Qualification of guidance and counselling personnel Quality of guidance services The table 1 shows an r. value of .169 testing at an alpha level of .05 and a p< .001. The p. value is less than .05 (p

Radiation Exposure and Radiation Diasters Affecting Marshall Island Research Paper

Radiation Exposure and Radiation Diasters Affecting Marshall Island - Research Paper Example The effects of radiation while dealing with radioactive material were demonstrated. The guidelines and limits were not established since the experience with radiation exposure was not enough to come up with a standard. To test the weapons, Nevada desert was used and underground tests were conducted to prevent massive radiation from affecting the ecosystem. However, as the magnitude of the projects increased, the US required a testing ground to effectively analyze the capabilities of the much higher yield weapons. Marshall Islands were taken from Japan during the Second World War and were administrated by the US under United Nations Trust Territory. These islands in the Pacific consisted of small islets and atolls. They were chosen as a proving ground for the nuclear tests. A total of 67 tests were conducted between 1946 and 1958 (Ferraro & Andreatta, 2012, p. 62). These explosions were mostly atmospheric and changed the ecosystem of the area. The paper will take into account the effe cts of radiation exposure and the magnitude of disaster on the Marshall Islands. Early Tests Two main atolls were used as testing grounds, Bikini and Enewetak. They are separated by 300 kilometers. The population was evacuated to safe distance on other atolls in the region, almost 200 kilometers away from the test sites (Angelo, 2004, p. 388). Bikini atoll alone experienced a total yield of 42.2 megatons during twelve years of testing. From 1946 to 1951, nine tests took place; eight of these tests were atmospheric and the yields were in kilotons, the highest being 225 kilotons (Nuclear Claims Tribunal, 2013). During the period, the fallout was controlled and the population was kept at a safe distance. The effects of these explosions were local and limited to some extent, however, in 1952, the yield drastically increased and 10.4 megaton test was carried out as opposed to kilotons before. The test left a crater of about 1 kilometer in diameter and the area was highly contaminated wit h radiation (CTBTO Preparatory Commission, 2012). The tests contaminated the soil by turning into radioactive materials. Thermonuclear Test The magnitude of tests increased and in 1954, hydrogen or thermonuclear bomb was tested for the first time. The yield was miscalculated and the outcome was almost three times the expected yield (Robbins & Adams, 1985, p. 12). The explosion was rated at 15 megatons and considered to be the most powerful explosion by the US. Furthermore, the wind condition at the test day was towards the population settlement on other islands. These two factors caused extreme radiation exposure to the inhabitants. Even with this exposure the affected community was evacuated two days after the test. Immediate Effects The immediate effect of the test included skin burns and hair loss in many inhabitants on the islands. The nearest island was 150, whereas, the farthest, 570 kilometers from the test site; however, a Japanese fishing boat about 150 kilometers was the n earest to experience the fallout (Lessard, 1986, p. 5). Debris including radioactive soil from the blast was received by the boat and from a crew of 23, one member died. The islands, however, received shower of radioactive particles in the form of ash carried by the wind. About 250 people were directly exposed to the radiation by the radioactive debris. The exact radioactive dose received by the inhabitants could not be determined as the

A CRITICAL REVIEW ON SURVEYS OF VALUE-BASED MANAGEMENT Research Paper

A CRITICAL REVIEW ON SURVEYS OF VALUE-BASED MANAGEMENT - Research Paper Example VBM has come to replace them all as a better management technique (Brigham, and Houston, 2009). though there is still something that cannot be taken for granted in any such novelty, i.e. the degree of efficacy in real world business contexts. It’s all the more imperative to consider this sudden spurt of interest in VBM as against profit-based approaches that were hitherto adopted by both small and big companies in order to measure financial performance of the company (Brigham, and Ehrhardt,2007). According to those vociferous critics of the method this annual ritual has had very little success by way of a system of acceptable metrics that truly demonstrated real or discounted cash flows of the company. Such palliatives are to be abandoned now and a more realistic system of metrics based on verifiable and measurable concepts ought to be adopted. It’s here that VBM comes as both a reliable tool and a systematic approach. Capital structure of the firm as divided into equity and debt has been of little significance to an outsider except for an investment consultant and a professional investor because the bewildering system of metrics doesn’t mean anything to the layman. This particular instance of failure associated with many other approaches to management has oft been cited as one of the very sound bases for a new management approach by critics. Thus the concept of VBM has come handy in this context too, owing to the fact that orthodox management approaches are all none too well defined to include performance related dynamics (Copeland, and Dolgoff, 2005). In other words capital must be invested in the business only when its rate of return exceeds the cost of it. Value parameters of VBM are quite well defined to include such variables as tax exemptions on capital investment and the corresponding value gains in alternate investments. Net returns on investment ought to be predictable and therefore uncertainty

Project Risk Management Coursework Example | Topics and Well Written Essays - 2000 words

Project Risk Management - Coursework Example Operations management deals with decision making related to productive processes to ensure that the resulting goods or services are produced according to specifications. Effective project management means getting the right things done according to the planned schedule. (Larson and Drexler, 2009, p. 1) Project management begins with planning. There should be an open communication among the members of the team and the aims and objectives must be clearly stated ensuring that they should be related to the objectives of the organization. The project life cycle begins when the project is started until it is declared completed. The key players include the customer who wants to buy the project; the contractor who works on the project up to completion; and the project manager who plans and manages the project activities until it is finished. Teamwork is an effective method in project management. Projects are initiated by recruitment and staffing and the selected team’s individual quali fications should correspond with the required skill for project success. While the group has to work as a team, there must be division of labor. For example, in engineering projects groups rely on individual members who work independently but are responsible to the group. Knowledge, teamwork and management, if studied carefully can provide aid for an effective project management. ... 310) In a project life cycle, we have a project manager, the customer, and the contractor. Moreover, before making decisions, we have to establish calendars. This has to be constantly consulted to see if the team is working as scheduled. This essay is about project management of an information technology application. There are many risks involved in information technology of an organization. The problem is IT security. The aim of this project management is to find a solution to the risks and threats in an information system of a particular organization. Main Body In the early 1900s, rapid industrialization brought in new perspectives to the growth of companies and organizations. Management scientists provided studies and introduced innovations in the workplace and how workers can be productive and relate their work with life. (Lock, 2007) Henry Ford introduced mass production which was also known as the Model T. Most important to project managers is the style of Henry Gantt who estab lished the Gantt Chart. Gantt worked for Taylor and popularized his style which is still used until today. Computers came in and finally the Internet. Manufacturing and construction industries took hold of the opportunity and recognized the many benefits of technology. In the 1970s, there was increase in the usage of information technology. Industrial project management continued as before but now this was added with project management software. With the emergence of the information revolution, project managers brought in a new face. They have to be well-versed in information technology, including how to manage computers and their security. (Lock, 2007, p. 3) There were different methods introduced at that time, particularly in the design and implementation, but some were put

Solution for Discrimination in the University Term Paper

Solution for Discrimination in the University - Term Paper Example The issue of discrimination in the universities had earlier been noted in the University of Michigan where the Supreme Court upheld the right of affirmative action in the University’s Law School for their belief that race as a factor creates ‘’a compelling interest in obtaining the educational benefits that flow from a diverse student body’’ (quoted in Brunner). As a university which is open and friendly to all races, the New Horizon University would not like to be a victim of the Michigan University’s case. Therefore, there is a greater need to revise the affirmative action policy in order to avoid its attempts to promote discrimination by its current affirmative action. This paper is set to provide a solution to the problem of racial discrimination at the New Horizon University by revising its affirmative action policy. The result should be a University that promotes fairness, equality as it strives to achieve its goal of providing education for all without any fear or favor. It all begins when a student needs an admission to the University. There has been tendency or an iota of likelihood that the University’s admission system is the core source of discrimination in the University (Sarah 2011). ... They might also have been forced to choose courses that they may have not wished to study. The university therefore needs to make a change in its system of admission that will firstly abolish the quota system of admission. Candidates who apply to be admitted in this University should not be required to give their details of origin and race. However, their names and sex can be indicated in order to help identify their letters of offer as well as allocate them to bed a space, which is done according to sex. Possibly, the University should acquire an automated or digitized admission system. This is where candidates will automatically be admitted to the University provided they attain the minimum requirements for the University admission. This system will be open and free on the University’s website to all candidates who wish to apply. It will be in the form of a form that the candidate will be required to fill up, and once they are through and have qualified as per the requiremen ts, they will get straight admission to the University. This system will prove effective as it will alienate admission system from direct contact of the University staff. Once the students have been admitted, there will just be a physical confirmation of their details with the details they gave during application. This is where their qualification will be verified as well as their identity to avoid cases of impersonation or use of fake documents. In this case, the admission process shall have been made free from discrimination and corruption. If there is a certain limit of the number of students that the University would like to admit, the digital admission system shall be made in such a way

Aviation Memory and Cognition Research Proposal

Aviation Memory and Cognition - Research Proposal Example Similarly, the National Transportation Safety Board (NTSB) found that on June 19, 2011 two aircrafts came â€Å"within 300 feet of each other† (à ir’, 2012). Cessna 172 and ExpressJet that was carrying 53 people failed to identify a conflict regardless of the fact that they were both connected with the radio traffic control. The Federal Aviation Authority (FAA) found that the controller who was on duty on the tower had a negative history of â€Å"professional deficiencies† with countless events where he disobeyed the standard procedures checklist that has to be followed at all times (‘Air’, 2012). This research paper aims to propose an investigative study to identify the factors that give rise to near-miss events by the ATCOs and how memory losses increases the number of near-miss incidents. The primary purpose of conducting this research is to bring to light the issue of near-miss by the ATCOs and the various factors that give rise to near-miss situations. This research proposal will provide a brief literature review on the topic, methodology, research design, expected outcome of the proposed research. Nashef (2003) highlighted that the concept of near-miss in air traffic control services refers to the loss of separation between two aircrafts in the air which if not prevent would lead to mid-air collision. Therefore, a near-miss is the situation in which the two aircrafts came very close to each other but did not collide. Nashef (2003) has categorized near-miss situations in three types, namely: Type 1, Type 2 and Type 3. Type 1 near miss is one where the incident has occurred and the installed system in the aircrafts successfully detected and corrected the situation. It worked as it was planned to work and therefore, no harm was actually done. Type 2 near miss is one where the incident occurred but one or more of the installed system in the aircraft actually failed to detect the loss of

Alcoholics Anonymous Meeting Experience Paper Essay

Alcoholics Anonymous Meeting Experience Paper - Essay Example It was on the latter end of the session when Ms Jenny linked the reading to alcoholism. This is where people started to share insights past and present on how family relations based on their own families were affected by alcohol. I thought the meeting was done in a relaxed atmosphere and the feeling of support was all around the place. I thought it was effective for the people to sit in a circle so that the group saw and heard each other with ease. The article was very effective in evoking insights on alcohol. The facilitator didn't start to pose questions to people, rather, the article led the discussion. It was able to open up discussion on alcoholism without much effort in asking people to share. I believe the meeting being not too short and too long is essential in keeping the people inspired to attend. Most of them were enjoying the sessions and this is important to keep the patients sustaining their commitment to the program. At first I was excited to get into the exercise but when I arrived early and saw Ms. Jenny and the seats arranged in a circle, I began to be nervous. I felt so incapable of the task because all my expectations came from media and television presentations that visualized the Alcoholics Anonymous as a stressful outpouring of emotions.

Crime in tourism destination Assignment Example | Topics and Well Written Essays - 500 words

Crime in tourism destination - Assignment Example street crime, where tourists are snatched off their bags, robbed off their possessions by criminals and in a few cases even violent robberies and rape perpetrated against them (Brosnahan, n.p.). The magnitude of this crime has been increased y the fact that it is not only perpetrated by the locals, but also by foreigners from neighboring countries, who have immigrated to Turkey, considering that it is a relatively peaceful country. In the crowded streets of the major cities such as Istanbul and Izmir, pick pockets take advantage of the congestion of people to pick any valuable the tourists might have such as money, watches, cameras and jewelry (Brosnahan, n.p.). The perpetrators of this crime have perfected this art through applying very unique tactics, which always leave the tourist lost and stranded. These criminals can engage in a street fight which will cause passersby to stand and watch the fight, while their colleagues take the advantage of this situation to snatch bags, valuab les or pick from the pockets of the bystanders (Brosnahan, n.p.). The other technique applied by the perpetrators of this crime is engaging is a street chase, where few of them chase after one of their own, causing commotion and confusion in the streets. This leave the tourists stranded due to the unusual scenes in a new environment, only to have the colleagues of these criminals pick from them or even snatch their bags and other valuables and then run to a waiting by taxi, which takes off immediately (Brosnahan, n.p.). Further tactics include a pretended collision between a stranger and a tourist, where the stranger pours some liquid on the tourists pretending it to be an accident, only to have the stranger pick from the tourists while pretending to wipe away the liquid. The same perpetrators of the crimes will engage in blocking the ways for tourists causing the tourists to be stranded, while others snatch or pick their valuables (Brosnahan, n.p.). They can also enter into tourist

Technology and Bullying Essay Example for Free

Technology and Bullying Essay I don’t know much about the topic I chose and I have never personally experienced bullying or cyber bullying myself. I have, however, seen on the news and read about cyber bullying and the growing trend it is becoming. I remember a very specific case that happened two years ago at Rutgers University where a closeted-gay college student’s roommate secretly videotaped him performing sexual acts. The roommate then released the video on the Internet and the gay college student committed suicide two days later. The case had just finished last month and the defendant was found guilty of a hate crime and sentenced to 30 days in jail. This definitely caught my interest toward cyber bullying and I started to take notice that it is happening frequently across the nation. I also know that currently forty-nine states have an anti-bullying law in effect. Part II – What I Want to Find Out From the research, I want to find out how technology is contributing to cyber bullying, or bullying. * How frequently do students bully other students? * When and where did the first cases of cyber bullying take place? * Is it just in the United States that cyber bullying exists? * Can bullying be prevented, and if so, how? Part III – The Search The word â€Å"bullying† is defined as using strength or influence to intimidate someone, forcing them to do what one wants. It is also used as a theme in many children and adolescent books such as Oliver Twist and The Chocolate War. Bullying has been around for as long as anyone can remember, possibly since the age of humanity began. However, only recently has bullying caught the attention of the public and scientific community. Dan Olweus, a Norwegian researcher, emerged with the first scientific studies on bullying in the 1970s. Bullying is now acknowledged throughout the world as an issue among children and youth, and research on the topic is increasing (Hymel, and Swearer). There is still scientific dispute as to the nature of bullying and why it begins. There are a multitude of reasons why someone feels the need or want to bully another person. Nevertheless, most researchers believe the aggression starts with wanting to cause deliberate harm to the victim, having the bullying occur repeatedly, and the difference of power between the bully and the victim (Olweus 422). One of the reasons may be because the person behind the bullying feels a â€Å"sense of power† when they harass someone. They like to become dominant in this situation and if the victim does become submissive, the bully feels as if they’ve fulfilled their goal and may repeat this process for a long time. Another reason may be that the bully wishes to befriend and feel close with the victim; to have a sense of belonging. As Dagmar Strohmeier states in her article Bullying and its Underlying Mechanisms, â€Å"If this wish for affiliation is a motive for bullying, the victim pl ays an important role in establishing and maintaining group coherence. If the harassment of the victim leads to a closer bond within the bullying group, the perpetrator reaches his goal and the negative behavior is reinforced.† As long as the victim is still submissive, the bully will constantly harass them until the bully is content (Strohmeier). When thinking of bullying, usually people think of a sort of physical interaction – the big kid picking a fight with a smaller kid. However, there are cases where numbers come into play; groups of students will pick on one individual. This is not uncommon and in fact, happens as often as one-on-one bullying (Hymel, and Swearer). There are, essentially, two types of bullying: physical and mental. Physical bullying is direct contact between the aggressor and the victim, and includes punching, kicking, pushing, or any physical contact with the bully and victim. The bully will not stop the violence until his or her victim is unable to retaliate back. Physical bullying is also not limited to school, and can occur at home, the office, or anywhere the bully chooses. Mental bullying may seem less harsh than physical bullying and may not physically damage the victim, but it can emotionally. Mental, or verbal, bullying involves name calling, making fun of a person’s appearance, a nd making offensive remarks to the victim. Making verbal threats of violence is also verbal bullying. There is also indirect bullying where the person will spread rumors and stories about someone else although it may not be true. This type of bullying accounts for 18.5% of bullying. Social alienation is another where the bully will intentionally exclude another from a group. But the type of bullying that is gaining ground is cyber bullying (Time for Tolerance). Cyber bullying is when a child or teen is being harassed, threatened, or embarrassed by usually another teen, and the bully is using the Internet, cell phones, or any other technologies. It includes sending threats or cruel messages to a person’s email account and cell phone. Cyber bullies also spread rumors online or through texts, and post unkind messages on web sites or social networking sites. Pretending to be another person using someone else’s account or making a fake account and sending harmful messages is another form of cyber bullying. Boys are more prone to take part in tradition bullying, physical bullying, whereas girls are more likely to cyber bully. (Bullying Statistics). Most cyber bullies and their victims are teens, and there are numerous cases where the victim being cyber bullied will harm themselves, and even commit suicide. Cyber bullying â€Å"has to have a minor on both sides, or at least have been instigated by a minor against another minor. Once adults become involved, it is plain and simple cyber-harassment or cyber stalking. Adult cyber-harassment or cyber stalking is NEVER called cyber bullying† (â€Å"Stop Cyberbullying†). In 2007, a mother created a fake account and posed as a boy to befriend a former friend of her daughter. The mother then began posting insults and creating posts about the daughter’s former friend which were hurtful and untrue. The teen, who was battling depression, soon committed suicide. It is hard to believe a parent or adult will do that to a child but there have been several cases where a parent will actually be the person cyber bully. Majority of the reason why a parent will cyber bully anoth er teen is because they believe they are protecting their children, but are, instead, harming another (â€Å"Stop Cyberbullying†). There are various reasons as to why teens feel the need to cyber bully someone. Sometimes the cyber bully is motivated by resentment or jealousy, and sometimes they do it for entertainment. Another reason may be because they are bored and have nothing to occupy themselves with. Some may do it unintentionally, and others do it for torment and to get a reaction from the victim. Although traditional bullying still occurs more than cyber bullying, the amount of cyber bullying happening in today’s world is consistently growing because of all the technologies being available. This means that cyber bullying happens worldwide and cyber bullies are sometimes strangers from halfway around the globe. (Patchin). Despite the seriousness and harmful effects of cyber bullying, it is common among teens and youth. According to a study done by the i-SAFE foundation in 2003, more than one in three teens have received and experienced cyber threats, and over 23 percent of teens are repeatedly through their cell phones or the Internet. Cyber threats are when teens post messages about harming themselves or another person and are sometimes followed by actual acts of violence. There have also been reports that cyber bullies will make FaceBook pages or web pages dedicated to insulting and bashing their victim, and 75 percent of teens have visited these sites. According to a UCLA study on cyber bullying, one in five teens report having been cyber bullied by someone they know or a complete stranger, and the study also found that 85 percent of teens that were bullied online are still bullied at school. Still, only 1 in 10 teens who have been cyber bullied tell a parent or adult and only 1 in 5 cyber bullying incidents are reported to law enforcement (Cyber Bully Alert). Currently, forty nine states have passed anti-bullying laws, and a number of state legislatures are proposing laws to require schools to have anti-bullying policies and programs. If someone is charged and convicted of bullying someone, they are charged with a misdemeanor and possibly serve time in jail. Cyber bullying is against the law but most of the laws in many states are not enforced because cyber bullying usually takes place outside of school. Still, that hasn’t stopped lawmakers from trying to enact and stiffen cyber bullying laws. At least five states want to add penalties to cyber bullying, and in 2009 North Carolina passed a law that criminalizes cyber bullying, making it a misdemeanor for youth under 18. Senator Jeffrey Klein of New York is one of the law makers that want to make sure cyber bullying can be punishable by law. Klein stated that â€Å"When I was growing up, you had a tangible bully and a fight after school. Now you have hordes of bullies who are terrorizing over the Internet or other forms of social media.† Under his proposed law, anyone that uses technologies to harass or stalk someone could be convicted of a misdemeanor or felony and face prison time. Some, however, oppose these laws believing that it limits freedom of speech (Alcindor). Although it may seem unlikely for anyone to not support anti-bullying laws, there are a few groups that are no in favor with the law at all. A group called Focus on the Family, a global Christian ministry, believes that these anti-bullying laws cross â€Å"the line in a lot of ways beyond bullying into indoctrination, just promoting homosexuality and transgenderism† (Hall). Focus on the Family has been a supporter anti-anti-bullying laws because they believe that these laws are a reason to teach children about gay marriage and not about bullying. Most of the groups that oppose anti-bullying laws are religious groups, and most agree with Focus on the Family. There have been a few states that have passed or tried to pass anti-bullying laws that protect bullies who use their religion as to why they bully others. This caused outrage among the public and most of these supposed anti-bullying laws have since been voted out or the specific clause has been removed (Hall). There are several ways to prevent bullying, or cyber bullying, from happening. First is beginning an educational campaign with children and teens, and informing others what exactly is cyber bullying and the steps to prevent it from happening to them. Teaching youth how not to unintentionally become part of cyber bullying will help slow down cyber bullies. Children need to be taught that being silent while another is being hurt is not alright, and if they stand up with the victims, cyber bullies can be stopped. Another way is keep personal information private. Children and teens should not share passwords with friends or strangers to keep themselves safe. Sharing this personal information can give cyber bullies the opportunity to hack into personal emails and social sites, and post damaging things online. And once things are posted on the Internet, it may be impossible to delete it permanently. Adolescents should also know that if they are targeted by a cyber bully to not respond and instead block the cyber bully and inform a parent or adult that can help them. Checking to see who they are sending messages and emails to is another way of preventing cyber bullying. Making sure that they are sending it to the right person and place will help stop cyber bullies from receiving private messages. Also, teens should know that it is not alright to forward and send other people’s emails and personal information without their permission. Teenagers also should not send emails or post messages online if they are angry. If they do, they may provoke the cyber bully and turn into a cyber bully themselves (â€Å"Stop Cyberbullying†). Part IV – What I Learned Through this research, I learned that cyber bullying is persistently becoming more known, and although traditional bullying still happens, cyber bullying is growing. Because of all the new technology becoming available to people of all ages, especially adolescent teens, it is easier for someone to become a cyber bully victim. Cyber bullying is also common in the lives of teens today, and happens worldwide. There are several effective ways to prevent cyber bullying and states in the United States are recognizing that bullying is a serious matter. Although bullying and cyber bullying cannot be stopped in a day, it is possible to stop bullies from hurting another person. Works Cited Alcindor, Yamiche. States look to enact cyberbully law.

Issues In Ethical Hacking And Penetration Testing Information Technology Essay

Issues In Ethical Hacking And Penetration Testing Information Technology Essay In this fast growing business world the growth of Information Technology is sky-scraping. Information is a business asset, therefore it is very important to protect the Business Intelligence and the confidential information. It may protect its availability, privacy and integrity. Information Security is more than protecting computer data security; it is the process of protecting the intellectual property of an organization which engages with Network Security. The availability of access to stored information on  server  databases has increased to a great extent. Most of the companies store their business and individual information on their computer than ever before. Many businesses are exclusively stand on information stored in their data centers. Personal staff details, client lists, salaries, bank account details, marketing, sales information and more importantly their research and development secret recipe or marketing strategies may all be stored on a database. If they lack this information, it would directly affect the business operations. Therefore powerful Information security systems needed to be executed to protect this information. The biggest threat to businesses may be the people who make a living from  hacking  or breaching through information security systems. By using their technological skills, they are brave enough to break into computer system and access secured information. Hackers can even turn your home computer into a bomb (Randy Jefferies, 2005). Firewalls, which are intended to prevent access to a computer network, can be easily bypassed by a  black hat namely a hacker with the right tools and skills. The breach can result a heavy loss of crucial information, or a virus could be planted and delete all secured information as an intruder. So that is why Information Security Professionals plays a vast role in this Business Industry, because of this, there is an important position for ethical hackers, who can defend and protect the organization against cybercriminals and even they are capable of penetrating their own system for the testing purposes .When the question arise that, is hacking actually bad? Or is it possible  that there are times when hacking can be seen as good? Before addressing  these scenarios, the term hackers and ethics needs to be defined. So this is where ethical hacker comes in. Ethical Hacking and Penetration Testing Ethical Hacking can be defined as hacking a network or a system to seek and test vulnerabilities that a hacker could exploit and take advantage of the system. This implies, doing it for the betterment of the firm. This process is done to secure and defend the system from cybercriminals known as black hats with a legally authorized way. The people who involve in ethical hacking are called as white hats who are professionally trained security experts. Most of the firms employ one these White Hats to protect their information systems whilst some firms hires. The Computer crime is where the computer is  the place of the crime and the criminal activities can range from  fraud, theft, and forgery. Businesses who try to approach the problem  have independent computer security professionals who attempt to break  into the computer systems and penetrate as mentioned above. Both of these people, crackers and  professionals are ethical hackers, but they have different ethics. Negative observation of hacking, When is hacking bad? In recent news, a certain hacker who claims to be  known as Gwerdna hacked into a Mac computer, He even made comments on  how easy it was for him to hack into the security and he has stated to break into that library machine he only took 10 minutes. (Micheal Harvey, 2006). The term Ethical Hacking can be addressed as penetration testing. This is a method of evaluating the network or computer system by simulating an attack from a malicious source, a White Hat Hacker but act as a Black Hat Hacker (Wikipedia, 2010). These ethical hackers use these methods which can be identified and clarified as malicious softwares namely Buffer Overflow, Logic Bomb, Parasite, Sniffer, Spoof, Trojan Horse, Virus, Worms. Importance and Benefits of Ethical Hacking As mentioned above the reason for conducting an ethical hack, obviously, is to keep information assets secure. One survey conducted by Rick Blum, stated that It (ethical hacking) is very important and helps save you money and reputation in the long run. (Rick Blum, 2009).Network testing is the most important type of ethical hack, because it is obvious the hacker can easily break the firewall and get into the network. So network should be highly secured. Thats a reason why it is considered as a very important fact for organization because of the rising cyber crime rates and the high growth of cyber criminals. Since computer technology has developed, the crime rates also increased. The intellectual hackers have made mass destructions and losses for many companies and they have damaged their database and leaked information. Had exploited the brand image of most of the firms and damaged their trust on their clientele. Hackers have transferred millions of dollars without any awareness of the banks and their involvement. Even hacked into police departments emergency help desks. For example a group of hackers called Vandals hacked the New York City Police Departments voice- mail system and replaced the usual polite announcements with You have reached the New York City Police Department. For any real emergencies, dial 119.Anyone else were a little busy right now eating some donuts and having coffee. It continued You can just hold the line. Well get back to you.Were little slow, if you know what I mean. Thank You. The bogus messages continued for 12 hours before they were investigated and corrected by ethical hackers (Donald Pimkins, 2000) Some time ethical hacking will not reveal vulnerabilities of a network or a system. But there are a number of consequence benefits that can be derived from an ethical hacking process. The picture below will give a clear idea of what are the benefits available in this process and how it can be prioritized. Ref: http://www.isaca.org/Images/journal/jrnlv2-06-red-teams-audit-tool-2.jpg The size of the threat depends on the type of the business and how its fits with hackers motives. Therefore to prevent these kinds of issues and threats in future firms employ ethical hackers. The term ethics will be clearly structured in the following paragraphs with the support of ethical principles, ethical issues, ethical dilemmas and ethical theories. Business Ethics According to the study Business ethics can be defined as a form of applied ethics that examine ethical principles and moral or ethical problems that occur in a business environment (Gwendolyn Cuizon, 2009). Many businesses have gained a bad reputation just by being in business. By not being stick to business ethics policy firms may fall in trouble, if a business is damaged by an ethical disaster it affects the bottom line which implies profit. It is agreed that IT systems are put in place to support the strategic planes of an organization which would be in lined with business ethics. So that is why organizations see ethics as, a bringing competitive edge to their business. In my point of view in business, the perspective view of stakeholders are different , they see theres whats illegal, whats legal but unethical, ethical but against company policy, not against policy but not in the clients best interests, and finally whats not really opposite to the clients best interests but isnt really going to benefit them moreover. Which can be understood by the below image. http://www.gryphonshafer.com/blog/2008/08/business_ethics.png Ethical Principles and Ethical Issues Ethical principles can be defined as the foundation of ethical behavior. An ethical principle arrives from the social Context, from religious beliefs, and from ethical theory. These ethical principles can applied to computer technologies that have an impact on peoples daily lives where they interacts in government, in education, at work, at play ground and workout) (Penny Duquenoy, 2010) Some general ethical principles can be listed as Respecting others Consider others as equal Keep promises Respect the property of others Act honestly The principles can be addressed as below which relevant to Information Systems professionals and related technologies officers. The Royal Academy of Engineering, in collaboration with Engineering Council (UK) and a number of the leading professional engineering institutions, has developed a Statement of Ethical Principles to which it believes all professional engineers and Information Professionals should follow. à ¢Ã¢â€š ¬Ã‚ ¢ Accuracy and Rigor à ¢Ã¢â€š ¬Ã‚ ¢ Honesty and Integrity à ¢Ã¢â€š ¬Ã‚ ¢ Respect for Life, Law and the Public Good à ¢Ã¢â€š ¬Ã‚ ¢ Responsible Leadership: Listening and Informing (Engineering Ethics, 2007) Ethical issues can be addressed as whatever threatens or breaks an ethical principle is an ethical issue. For example ethical principle Respect the property of others Ethical Issue Hack someones computer without their permission and steal information and destroy it by sending a virus or a worm So by understanding this example an ethical issue can be clearly understood. And to assess these kinds of ethical issues in different perspectives ethical theories should be applied. Ethical Theories As discussed above an ethical issue can be identified and evaluated by using ethical theories .These theories can be used as tools for making ethical decisions, and they may also helpful in providing a basis for critical thinking. An issue can be taken in different perspectives and formed opinions with helpful of ethical theories. There are two main ethical theories, Kantianism Consequentialism Kantianism The Kants theory can be defined summarized without going in deep. Kant says that how we behave ethically comes from within us, and the things that we decide are good or bad are based on whether we could imagine everyone doing them. (Immanuel Kant) So for example, it would be logically conflicting to say that breaking a promise is good because if everyone broke their promises there would be a loss of trust in promises, and the whole nature of a promise would be lost. Therefore, he says, that certain things cannot be universalized which means they would not work if everyone did them, and those things are wrong. Examples are: killing others, lying, stealing, breaking promises. Moreover, in Kants point of view, things that we view as wrong are essentially wrong that is, they are always wrong and there is never any reason situation where they would be right. This conflicts directly with the theory of consequentialism, which will be addressed next. Consequentialism Consequentialism theory can be defined as, a theory which deals with consequences of actions rather than the actions themselves .So, and for example, it could be argued that stealing could sometimes be the right action to take provided the outcome is for the good. Theory says that a good outcome is that which brings the greatest benefit to the greatest number of people. Therefore stealing, for example, is a morally acceptable act if it brings greater benefit to the greatest number. For example, if a king has a warehouse full of food when most of the people in the country are starving. In this instance stealing the food to distribute it to the starving people would be the right thing to do. So by this act a great number of people get benefited. So in this case according to consequentialism theory stealing is not bad while it fully contradicts with Kantians theory. Ethical Dilemmas Ethical dilemmas can be addressed as moral dilemmas. An ethical dilemma is a situation where in moral principle or ethical obligations conflict in such a way as to make any possible resolution to the dilemma morally intolerable. In other words, an ethical dilemma is any situation in which guiding moral principles cannot determine which course of action is right or wrong. Can simplified as you will have issue and you will have a solution which will leads you to an unethical way.(Lee Flamand, 2007). Ethical, Legal, Professional, Social and Cultural Issues in Ethical Hacking When we discuss about ethical hacking there are many issues which can be listed, which will arise in many circumstances. For evaluating these issues and come up with a good solution or opinions the above discussed, structured ethical principles and ethical theories can be taken off. This will obviously give a clear picture to the reader. In this study for further more analysis two important incidents will be assessed by me using the both ethical theories. A Dutch hacker who copied patient files from a University of Washington medical center (and was not caught) said in an online interview that he did it to publicize the systems vulnerability not to use the information. He disclosed portions of the files to a journalist after the medical center said that no patient files had been copied. (Sara Baase, A Gift of Fire, 2003.) If we critically evaluate the above scenario, it is obvious that the hacker has committed a cyber crime and he should be punished according to the Kantianism theory which tells some actions are always wrong. Even though the Dutch hacker didnt misused the copied files he has break into the network and penetrated it. So its ethically wrong when we see in the perspective of Kants theory. But if we evaluate this using Consequentialism theory it will completely contradict with Kantianism theory. Though the hacker was not get caught he has came to an online interview to announce that there is vulnerability in University of Washingtons medical centres network which can be easily attacked. So this good behavior of the hacker shows that he has came to this decision concerning about the betterment of the patients. which direct the theory an action is good If the consequences bring greatest benefit to number of people .If he has published all the copied files through the internet the both parti es will be get affected, the patients and the University. The files may contain confidential information of patients and which they never want to expose. So although this act can be identified as ethically correct whilst its legally wrong. Therefore by this action the Medical centre gets a chance to secure and defend their systems from future attacks. But a according to the statement A solution to an ethical issue can raise another issue Anonymous. May be this act is ethically correct according to the theory of Consequentialism. But what if the hacker found some medical information about his friend? Which information is a kept secret? What if he tells him? What if the friends get to know that his confidential medical information has got leaked through the internet? These kinds of issues can arise which will sometimes take into an ethical dilemma. If we move to the next case which is, A 17 year old hacker know as YTcracker, who penetrated several government and military web sites (including those belongings to the Bureau of Land Managements National Training Center, NASAs Goddard Space Flight Center and the Defense Contracts Audit Agency) said he routinely sends messages to government web site administrators insisting that they address vulnerabilities and adopt Unix or other more secure systems can be penetrated, but the messages largely go ignored. YTcracker said in his defacement of website he targeted systems the government would look at and take seriously and secure it. (Federal Computer Week, 1999) Though this case is Similar to the above discussed one, it provides a different idea. The hacker who has penetrated all these sites called YTcracker has only one intention that is to alert and notify the government organizations to protect their valuable informations, Which can be easily breached and gained access. If critically evaluate this case according to the Kantianism theory. The act of YTcracker is ethically wrong as it threatens the ethical principles go beyond the theory. But according to the point of Consequentialism theory the act is ethical. Because the hacker hasnt done any damage to the government organizations using their web sites. He has only warned and notified them to make them more secured. So greater amount of people gets benefited, because there are most sensitive informations are available in government sites such as National Security, Military and NASA. So if the hacker leaks the information from their databases what will happen there are would be a huge problem for the US government. But both of these incidents are illegal according to the Computer Misuse Act 1990 even they are ethical according to the theories. Because the hackers have offended unauthorized access to computer material (Misuse Act 1990) Ethical Concerns and Professional Issues When implementing an ethical hack in an organization there are ethical issues which engages with information systems professionals can be addressed as, Ethical Hackers have to break the organizations security policy and procedures. Violating the code of conduct. Privacy of the employer and employees Secret Business strategy, Marketing Strategy and product recipe leakage If we further analyze above ethical issues a question may arise, Does ethical hacking is ethical? Before address the issues, we are tend to find a solution for the above question so if, we evaluate the question by putting into Kantianism theory somehow its breaking the rules and regulation, braking the firms security policies and procedures, penetrating the code of conduct. So this act of ethical hacking can cannot be ethical. Even though the professional hackers do it legally it can be unethical, According to Kants point of view. Considering with view point of consequentialism theory this process can be identified as ethically correct, because its all done for the betterment of the organization. So there is no way of criticizing it. Firms do these to seek the vulnerabilities and defend the entire network there should be a testing procedure. So this can be taken as that. In this point of view we can decide its all ethically correct, even though they break their own code of conduct. As information systems professionals point of view ethical hacking can be identified as a complete mess. Because they have to stick to a code of conduct. Then only they are professionals. But when they are being forced to violate these terms when they involve in penetration tests there are in trouble as professionals. Therefore as professionals who are expected to comply with local laws, sometimes they may have to assess and evaluate ethical and legal issues against their personnel values. There can be privacy invasion takes place when they do a ethical hack. Most of the firms hire an ethical since they dont employ one. So when he penetrate their systems and network he can get whatever the information he needs from the organizations databases and networks. All confidential employee and partner documents and information can be seen. The ethical hacker is able to view all the weak points of the firewall. If the ethical hacker is not a professional he may attack the organization later when he needs. Or he will be a big threat. So these issues may arise. And even the secret marketing and business strategy of a leading company leaks the hacker can sell it for the competitors. So this would be a threat for some firms to conduct and penetrations test using an Legal Issues and Laws When considering about legal aspects, the issues which was discussed in the above paragraphs can be brought up since it involves legal issues. Even though those incidents were ethical, its completely illegal, because it breaks the Computer Misuse Act 1990. This Act will be clearly discussed below, The Computer Misuse Act 1990 The  Computer Misuse Act 1990  is an Act of the  UK Parliament. The Bill eventually became the Computer Misuse Act in August 1990.The Act introduced three new criminal offences: Unauthorized access to computer material Unauthorized access to computer material with the intent to commit or facilitate commission of further offences Unauthorized modification of computer material.(Statuelaw, 1990) What if an ethical hacker pretends to be an inside intruder? He who knows the entire network and secrets of a company. So he can easily damage and destroy the entire information system. When these situations occur according to the misuse act legal issues can be identified. For an example a disgruntled computer technician at Reuters in Hong Kong detonated logic bombs at five investment-bank clients, causing 36 hours of downtime in networks providing market information crucial for trading. The banks switched immediately to alternative services and reported no significant effects on their work; however, Reuters was deeply embarrassed by the incident (Financial Times Limited, November 1996) so looking into these factors the organization should be fully aware of these kinds of threat which can be aroused. Sometimes Internal politics may force the ethical hacker to make huge losses for the firm. When they employ for and public company. There are so many people in a director board. So what if the ethical hacker gets an order from higher management to plant a logic bomb or do a parasite for important information of the firm and put the blame on another person. For the ethical hacker this job is not that much difficult. Even they may ask him to steal other companies confidential documents. This might cause legal issues which will entirely damage the firms reputation. These kinds of issues can arise without the awareness of the management. Social and Cultural Concerns It is agreed that in business ethics there are loads of issues as deeply addressed in above paragraphs and social and cultural issues can also identified as one of them. Social issues are about to impact on the society. IT depends on the societys reaction and behavior. According to the ethical principles firms should negotiate with the society. If an Information System of a Hospital or a School got hacked, there would be huge issues in the society. As their sensitive information contain on those Information Systems. Similarly this case may occur in a firm. So when an ethical hacker gets involved in this process he has to keep the trust on them if not the blame can be put on him by the society. So both parties get affected. The brand image can be get spoilt in the society when their informations get leaked out. They will lose the trust and faith on their employer. And when the ethical hacking process gets leaked out there are chances of affecting the companys culture. If there is a culture there are certain values to be respected. And if this values get exploited by the penetration testers issues may arise. And when they design these IS system they should respect the values without harming it. For e.g. Pornography. Conclusion From the clearly structured study, it is understood ethical hacking consideration is crucial to maintaining a verifiable level of information security. Even though there are lots of issues in certain aspects of Ethical hacking; it is a critical component of our overall security program which keeps the internal, contracted security. Ethical hacking is a necessity in order to protect company assets and stay close to the reality of unethical hacking. It ethical hacking is very important and helps save you money and reputation in the long run. Ethical Hacking is the best way to assess the network from an outsiders perspective. To reduce the addressed issues above organizations can have their own ethical hacking team or hacker to prevent outside information leakage and to get rid of the fear of that. I think ethical hacking is a must have for any serious organization today in this fast moving business world. It should be a critical part of any proactive organization in todays global competitive market.

Keeping up with the Jones :: essays research papers

The expression, â€Å"Keeping up with the Joneses† a very common quote that, Juliet Schor, used in her work, The New Politics of Consumption, could not fit a society more. The average household debt excluding mortgage is estimated fifteen thousand dollars, eight thousand of that debt comes from credit cards. (Paul Bannister, bankrate.com) Credit cards are becoming a huge problem in our society that it is affecting more than just consumerism. It’s affecting the way we live.   Ã‚  Ã‚  Ã‚  Ã‚  Everywhere public place you go it is hard not to run in to the idea of the credit card. You will see credit card logos on the front of every business. Every department store you go in has it’s own version of a credit card from Target to Macy’s. The Diner’s Club Card that originally was only for businessmen to eat lunch at 27 different restaurants. Now it is accepted almost everywhere. And for everything else there’s Mastercard†¦Ã¢â‚¬ ¦(or Visa, Discover Card orAmerican Express. Currently there are 1.2 billion active credit cards used in the United States. A typical purchase on a credit card cost more than 112% then a purchase paid for by cash. Americans are not only purchasing items on their credit cards as they go on shopping sprees. They are now paying their rent, tuition, utilities, car payments, and anything else they can think of. 9 in 10 credit cards users say that their credit card debt is nothing they worry about, but 47% of these people refused to tell a friend exactly how much they owe. (Paul Bannister, bankrate.com).   Ã‚  Ã‚  Ã‚  Ã‚  Initially when people receive a credit card they state that it is for â€Å"emergency purposes only†. However, that does not seem to be the case. For some, keeping up with the Joneses is an emergency. Heaven forbid, a sale at the GAP. Fewer people are saving money. Instead they rely on the plastic. However, the average credit card holder pays $1200 just in credit card interest. You would think that those individual would figure this out and start putting that $1200 into saving for â€Å"emergency purposes only†.   Ã‚  Ã‚  Ã‚  Ã‚  It seems odd that so many people say that they their credit card debt is nothing they worry about. When people have been filing bankruptcy more and more. In 1991, the rate of 25 years and under that filed for as rose to 50%. Maybe this has to do with so many Universities and Colleges allowing banks and credit card companies to hound financial uneducated students on campuses with promises of a free calling card or hopes of winning a plasma TV for their dorm room.

Un-Victorian Tenets of Brownings Strange Medical Experience of Karshish, the Arab Physician :: Strange Medical Experience of Karshish

Un-Victorian Tenets of Browning's Strange Medical Experience of Karshish, the Arab Physician Robert Browning's "An Epistle Containing the Strange Medical Experience of Karshish, the Arab Physician" is a dramatic monologue in which Karshish writes to Abib about his experiencing the miracle of Jesus, when he raises Lazarus from the dead. "Karshish" is a dramatic monologue containing most of the tenets of Browning. Although "Karshish" is in the form of a letter, it is still an excellent example of a dramatic monologue. There is a speaker, Karshish, who is not the poet. There is a silent audience, Abib the reader of the letter. There is a mental exchange between the speaker and the audience: Karshish writes as if Abib were right in front of him listening to everything. This can be seen in the hang between "here I end" and "yet stay;" it is as if Abib were getting up to leave (61-2). There is a distinct critical moment, when Karshish decides to write about his original concern: "Yet stay. . . I half resolve to tell thee, yet I blush/ What set me off a-writing first of all" (62, 65-6). "Karshish" has all the basics to a dramatic monologue. It also contains a character study in which the speaker speaks from an extraordinary perspective. Karshish is a humble doctor from one of the most civilized nations of the time, he has seen most of the civilized world, and he is still amazed by the miracle that he witnessed. His amazement after having seen many great things in the world proves to the audience that this event was indeed spectacular and significant. In the non-Christian world, the most common response is to doubt and to reject, but because of the conviction of the speaker the audience believe that the miracle did happen. This contrast between doubt and believe creates the dramatic tension of the work. Thus, "Karshish" contains the character study and dramatic tension which make the work a dramatic monologue. "Karshish" contains many of the tenets of Browning. One of first tenets noticed is the idea that physical success in this life does not correspond to success in the next. This can be seen in the peaceful "carelessness" seen in Lazarus after being raised from the dead despite the

Public/ Private Parents these days try to find the best school for their child’s needs. Some parents can’t choose between public and public schools, because of their differences. Public and private schools have a lot of difference like cost, admissions, teachers, students, and special needs. Public schools don’t have tuition as all people know. State, Federal, and local taxes fund public schools. So when you pay taxes, you are paying for child’s education. Also you are paying for the other kids in your community. Unlike public schools, private schools have tuition. The National Association of Independent Schools says that the median tuition in the United States is $12,000 for first to third, $13,000 for grades sixth to eighth, and $15,000 for grades nine to twelve. For boarding schools it’s like another $8,000 for each group (Education World). Another difference is the admission. Public schools admit all children. This includes students with special needs. You can enroll your child in public schools by just filling out the necessary paperwork. Some private schools on the other hand are selective. Private schools are not forced to accept every child. In many schools admission is very cutthroat. The teachers are another difference in public and private schools. The teachers in public schools are usually state certified. That just means that the teacher has gone through training required by the state. In private schools teachers may not be required to have to train. Instead they have subject area expertise and an undergraduate or graduate degree in the subject they teach. Also teachers in private schools often report better working condctions. The students in public schools are usually the kids from the neighboring community. Also public schools usually have more racially and ethnically diverse populations. On the other hand a process determines students that go to private schools. All students must apply and be accepted in order to attend. Some people may say that this can create a fairly homogenous student body. Another difference is the special needs. Public schools by law must educate all children. They also have to provide the necessary programs to meet the child’s special needs. Public schools have teachers who are trained to work with students who have specific needs, because of this law. However, private schools don’t have to accept kids with specific needs. As a result most private schools do not have special education programs. Also in private schools extra resources to help children with special needs may come at an additional cost (Greatschools).

This acquired primary data will give us an insight student trends and insight into the most effective marketing strategy Research/Discover from students, what their wants/needs are from a salon Pamper Me may not currently be meeting the needs of the desired student consumers. Collated data from primary and secondary research will advise us on how to increase the number of students using this salon Define main competitors to the business and map out their market & physical positioning Primary and Secondary research will be carried out in the area surrounding Pamper Me in order to locate the competition. The marketing plan may suggest to mirror competitor strategies if these seem to increasing the student percentage of consumers. Analyse current marketing strategies with a view to creating a new and improved strategy Current marketing strategies in place by Amara may not be sufficent or beneficial to Pamper Me. A new approach may be needed and it is vital that  all employees understand the new strategies once they are in place. To create or identify a Unique Selling Point (USP) for the business based on their expertise and specialties Currently Pamper Me’s USP is that it provides private and noninvasive treatment rooms for religious women. This isn’t widely know by the community so a recommendation must be suggesting in order to increase the awareness of this. Religious students may not know that there is a salon the adheres to their faithful rules. Implement a marketing strategy that can inform and attract students to the salon We must research and analyses what inspires students to spend money on beauty treatments. As students don’t have a high level of disposable income it is important to implement a marketing plan that is constructive and beneficial for students.

The Effects of Sleep Deprivation on Various

Sleep deprivation is a common occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they need, this belief is false. Sleep, by definition, is the natural periodic suspension of voluntary bodily functions and complete or partial suspension of consciousness, during which the powers of the body are restored (Ratcliff & Van Dongen, 2009). Only in the last century have the psychological and scientific areas of study began to investigate and explore the nature, purpose, and properties of sleep. The purpose of this essay is to analyze the value and effect of sleep deprivation on cognition. The majority of articles describe partial sleep deprivation as having negative effects on cognitive, behavioural, physiological, and emotional measures. From this information, it is derived that various cognitive abilities will affect productivity and performance. Therefore, it is hypothesized that sleep deprivation affects cognitive, behavioural, physiological and psychological measures because it increases and worsens stress, impairs cognitive function and emotional stability. How an individual responds to sleep loss, whether it is partial deprivation (sleeping less than 5 hours in one 24-hour period), short-term total sleep deprivation (no sleep for 24-48 hours),and long-term total sleep deprivation (no sleep for more than 48 hours) can vary. Ratcliff et al. 2009) indicate that sleep deprivation has been shown to impact negatively on a wide range of cognitive abilities, such as behavioural, physiological and emotional. For example, mood changes including irritability, fatigue, difficulty in concentration, and disorientation to short-term memory alterations are due to decreased attention, concentration lapses, and decreased motivation. Similar results were published by Alhola & polo-Kantola (2007). The study concluded that the person deprive d of total sleep experiences negative mood, sleepiness, fatigue, and decline in alertness and performance. Some sleep-deprived individuals report visual hallucinations or distortions and feelings of paranoia. Systematic studies of total sleep deprivation have revealed some temporary cognitive deficits but no permanent effects. Kloss, Szuba & Dinges (2002) discovered the most significant effect of sleep loss is the physiological sleepiness, or the tendency to fall asleep when there is a lack of stimuli. Sleepiness becomes extreme after the loss of a single night of sleep. Without competing stimuli, an individual lacking a night’s sleep can fall asleep within 2 or 3 minutes the next day. This can cause dramatic affects on productivity. After about 48 hours without sleep, microsleeps become increasingly more common even when participants are physically active (Kloss et al. , 2002). Microsleeps are essentially several seconds of actual sleep with delta waves that interrupt the regular EEG of a person who is awake, which impairs his or her continuity of cognitive function (Kloss et al. , 2002). Therefore, as sleepiness increases, an individual must increase effort to maintain a stable level of performance because microsleep generally happens directly before performance failure occurs. In addition to the impairment of cognitive functions, adult symptoms of sleep deprivation may vary from those of a child. Yawning constantly, dozing off while watching a television show, poor concentration and grogginess while waking up are some of the symptoms adults display when they are deprived of sleep (Dahl, 1999). The symptoms of a sleep-deprived child include irritability, daytime naps, tantrums, hyperactive behaviour, and moodiness. Getting out of bed in the morning is a problem for children who experience sleep deprivation. Adolescents also experience a change in their sleep patterns that their bodies want to stay up late and wake up later, which often leads to them trying to catch up on sleep during the weekend (Dahl, 1999). This sleep schedule irregularity can actually aggravate the problems and make getting to sleep at a reasonable hour during the week even harder. According to Dahl (1999), following sleep loss and hyperactive behaviour, changes in attention and performance also represent a complex area of investigation in children and adolescents. Sleep loss is associated with brief mental lapses in attention during simple tasks that can be partially offset by increased effort or motivation. Sleep deprivation can sometimes mimic or exacerbate symptoms of Attention-Deficit Hyperactivity Disorder (ADHD), including distractibility, impulsivity, and difficulty with effortful control of attention. There is also emerging evidence that sleep deprivation has marked influences on the ability to perform complex tasks or tasks that require attention in two or more areas at the same time (Dahl, 1999). Therefore, a teenager should try to go to bed at the same time every night and wake up at the same time every morning, allowing for at least 8 to 9 hours of sleep. On the other hand, many people are suffering from daytime sleepiness so pervasive that it interferes with their daily activities because they do not get the optimal amount of sleep they their bodies need. Lack of sleep and sleep problems can have serious, life-threatening consequences, as well as a significant impact on productivity (Alhola et al. , 2007). Many people suffering from routine sleep loss are not even aware of it, and many who do realize they are not getting enough sleep are not aware of what it is costing them. Sleep loss creates sleepiness, which can be associated with decrements in vigilance, reaction time, memory, psychomotor coordination, information processing, and decision-making (Rosekind et al. , 1996). With increasing sleepiness, individuals demonstrate poorer performance despite increased effort, and they may report indifference regarding the outcome of their performance. Even severely sleep deprived people are still able to perform to some degree on a verbal learning test. This implies that some other area of the brain must become active to compensate for the loss of temporal lobe functioning. Even though they can perform to some degree, sleep deprived people still do not perform as well on these tests as do fully rested subjects Rosekind et al. (1996) illustrate that not getting enough sleep affects the people in several ways, such as problem solving skills are impaired. Sleep loss noticeably impairs our ability to comprehend apidly changing situations, increases the likelihood of distraction, makes us think more rigidly and less flexibly, and reduces our ability to produce innovative solutions to problems. In addition, our communication skills also suffer because sleep loss reduces the words in vocabulary both verbally and in writing (Rosekind et al. , 1996). Learning and memory suffer as sleep loss diminishes scores on tests of memory, verbal fluency and overall creativity (Rosekind et al. , 1996). Therefore, if a person is not able to get a full night's sleep after learning something new, he will not remember the new knowledge well. He will not fully assimilate the new ideas or task until he is able to go through a complete night of uninterrupted sleep cycles. In relation to our communication and memory skills, being sleepy on the job, whether the cause is simple sleep deprivation or an undiagnosed or untreated sleep disorder, can also have a vital impact on how well workers can do their job. For example, night-shift workers have poorer daytime sleep, reduced night-time alertness and performance, and an increased accident rate (Williamson & Feyer, 2000). Since sleep deprivation causes individuals to feel so sleepy during the day, their concentration and performance suffer significantly. For example, sleep deprivation often leads to an increase in the incidence of motor vehicle accidents. One study found that individuals suffering from fatigue due to sleep apnea are six times more likely to have a motor vehicle accident than persons who are not suffering from fatigue (Williamson et al. , 2000). This is partly due to the person being groggy or sleepy due to lack of rest. It is also partly due to the fact that sleep deprived people tend to fall into sleep for very brief periods at unforeseen times. They also are more disposed to industrial accidents than non-apnea workers (Kloss et al. , 2002). Therefore, there is a direct connection between sleepiness and impaired hand-eye coordination. The degree of impairment has led researchers to compare it in severity to drunkenness and this can be represented by having an untreated sleep disorder such as insomnia, narcolepsy, or sleep apnea significantly increases the risk of having a motor vehicle accident. Since sleep deprivation increases the likelihood of having a motor vehicle accident, sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally (Landsness et al. , 2009). After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly affecting a person's behaviour. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting (Landsness et al. , 2009). This could involve lying awake but relaxed within a quite environment. Different parts of the brain are rested and regenerated during different phases of sleep. During some phases of sleep, the neurons in the cerebral cortex regenerate (Landsness et al. , 2009). If sleep is interrupted so that this regeneration cannot occur, speech may be affected, since the temporal lobe of the brain is what controls speech (Alhola et al. , 2007). People who do not get enough sleep often have slurred speech. There is also measurably less activity in their temporal lobes than in those of well-rested people (Alhola et al. , 2007). During Rapid Eye Movement (REM) sleep, memories are consolidated and categorized by the brain (Ellenbogen, 2010). New synaptic connections are also formed during REM sleep, aiding learning. If REM sleep is cut short, long-term memory may be affected and new knowledge might not be retained (Ellenbogen, 2010). Conversely, short-term memory might be better in the sleep deprived person because the part of the brain that controls short-term memory contains memories that are still fresh. In order to counteract sleep deprivation effects, the brain works harder but the effectiveness is low. There is a drop in the concentration level and it affects memory too (Lim & Dinges, 2010). The effects of sleep deprivation include slurred and fragmented speech and slowing down of mental reaction time. Problem solving and decision making abilities of the brain are affected. Due to rigid thought patterns of the brain, new problem solving ideas do not get generated, and hallucinations are common for people who have insufficient rest (Kloss et al. , 2002). Sleep deprivation causes deterioration in emotional mood of human beings. Irritability and short temper are two common symptoms of sleep deprivation (Dahl, 1999). Consequently, emotional outbursts and even violence are noticed among people who are deprived of sleep because of a loss of emotional control (Dahl, 1999). Sleepiness leads to rise in stress and anxiety levels of these individuals. Stress and anxiety in turn will lead to insomnia and this kind of vicious cycle will lead to anxiety disorders and depression, if left unchecked. Our emotional moods are affected by exhaustion and fatigue. This condition in turn will lead to pessimism, sadness, stress and anger (Jennings et al. , 2003). To function effectively, the frontal cortex of our brain needs sufficient sleep. The ability to control speech, problem solving and accessing memory is all controlled by the frontal cortex and if there is not enough rest, these abilities are affected (Landsness et al. , 2009). One thing is for certain, that chronic sleep loss may lead to deterioration of mood and motivation, decrease in attention, energy, and concentration. It also causes an increase in fatigue, irritability, tension, anxiety, and depression (Jennings et al. , 2003). Any one of these consequences of sleep deprivation can seriously affect productivity and performance. There is no question about it that the problem of sleep loss and fatigue is one that impacts significantly on the professional and personal lives of all humans. In association to all these studies, the purpose of this essay was to analyze the importance of sleep deprivation on cognition. There is considerable evidence to support the hypothesis that sleep deprivation has negative effects on neurobehavioural (sustained attention, reaction time, and vigilance) and cognitive (memory and reasoning) performance in humans (Rosekind et al. , 1996, Williamson et al. , 2000, Kloss et al. , 2002 & Alhola et al. , 2007). In some ways, sleep deprivation studies help us to study and understand the relationship between the brain and behaviour in a very unique way by observing how a person's behaviour changes as the brain shuts down. Just like a person cannot jog for three continuous days, a person's brain cannot operate without rest breaks. Since different regions of the brain rest during different stages of the sleep cycle, sleep cannot be cut short (Landsness et al. , 2009). Therefore, too little sleep can influence our intellectual capabilities, emotions, and motor performances, which creates major issues for sleep deprived drivers because they are falling asleep at the wheel. To reduce our behaviour in sleep deprivation, it is important for us to manage our activity so that we have more time to sleep. So, to have a good quality and quantity of sleep, time management is the key.
