Journal - Assignment Example As a function of analyzing this dynamic, the following discussion will focus specifically upon two distinct minorities: African-Americans and Japanese Americans. With respect to African-Americans, not a great deal of benefit was achieved on their part as a result of the United States involvement in the Second World War. For the most part, racism, segregation, and the enforcement of Jim Crow laws within the South remained largely unabated. Faragher points out that the social norms and racial disparaties experienced by African Americans, specifically in the South, did not alter greatly as a result of WWII (Faragher, 691). However, it is also fair to note that many African-Americans were able to engage with the workforce in a manner that they had previously been unable to do. For instance, the high demand for labor and the production of war material created a need for all able-bodied employees to land their services to this effort. As such, African-Americans that had previously been passed over for factory jobs or production jobs were hired and began to learn valuable skills that were utilized once the Second World War concluded. In such a way, African-Americans indirectly benefited from the overall level of training and engagement in the workforce that the Second World War was able to provide. However, by means of comparison and contrast, their participation in combat was still segregated as compared to white soldiers and they were deemed as inherently less valuable by almost each and every military leader (Best 203). Likewise, in terms of the overall impact of the Second World War on Japanese Americans, the analyst should necessarily consider the fact that this particular conflict drastically reduced their standing within American society. It further partially destroyed their civil rights, and ultimately set this

Compare and Contrast 2 literary works Research Paper
Compare and Contrast 2 literary works - Research Paper Example The storm also depicts an adulterous relationship between two ex-lovers. As the storm approaches and progress they engage in an illicit relationship despite the fact that both of them are married. The storm helps in rekindling past coveted memories between the two of them. Alcee maintains in the story that he was not able to follow his aspirations and feelings he had for Calixta. On the other hand, the author, Kate Chopin tries to convey her opinions by means of Calixta. Her character is that of a women who is tied with her husband. After engaging in an adulterous relationship with Alcee that day, she finds herself happy and refreshed. Chopin tries to convey through this act that marriage is an institution which ties two individuals together and they are not able to obey their own free will. On the other hand, the case with Alcee is somewhat different as he is not with his wife and feels lonely. He feels comforted and soothed and his loneliness disappears after engaging in sex with C alixta. By means of these two principal characters, Chopin tries to depict that having an illicit relationship is not necessarily detrimental. ... Also nature has the healing power to modify emotions and feelings of individuals. This is depicted by the end of the story and is depicted by the following quote, Was it last week the cyclone had well-ruined him? The cyclone seemed a huge joke, now. It was he, then, who, an hour ago was kissing little Calixtaââ¬â¢s ear and whispering nonsense into it. Calixta was like a myth, now. The one, only, great reality in the world was Clarisse standing before him, telling him that she loved himâ⬠(Chopin 160). This quote further brushes off the impositions posed by morality. According to Chopin, just by bonding in marriage and getting tied up in a relationship may not necessarily depict astute happiness in individuals. In fact, sometimes straying away from the path may result in satisfaction and comfort, rather than the feeling of guilt which is imposed by the implications of being ethical and moral. The characters of Calixta and Alcee do not experience any guilt by engaging in an adu lterous act because they themselves feel freed from all the negative emotions they experienced in marriage. In fact, the adulterous relationship helped them in bouncing back to their respective marriage with happiness and vigour. This sentence also shows the resignation towards societal rules. Despite having an adulterous affair with Calixta, Alcee returns to Clarisse, his wife as he believes that this is the only socially acceptable relationship. There is another aspect of symbolism depicted in Kate Chopinââ¬â¢s The Storm. This can be seen in her silent symbolism against Catholicism which denotes certain restrictions on gender and sexuality which is forced due to class and religion by means of certain cultural constructs which existed during that time (Wehner, 154).

The Impact Of Computers In Our Daily Lives Computer Science Essay
The Impact Of Computers In Our Daily Lives Computer Science Essay Computers are commonly used items in many fields in our present world as will be in the future. Since the ages of the fathers of computers like Blaise Pascal and Charles Babbage. These machines have proven to be very essential or important and significant especially for people who run large organizations and industries, but also to the individuals themselves. Computers have affected our lives in a great deal in that almost every thing now is either run by or made by computers. For instance, in large industries, cars and space exploration devices and machines are designed by the use of computers, in hospitals where medical billings, patient admittance and other medical equipments are run and made by computers; traffic lights that run the city traffic are run by computers. One of the major impacts of computer is communication. The level of communication has gone higher through computer as now you can be connected with friends and family around the world, many business deals and conference is now made through the help of computer. Nevertheless the entertainment world would not have been as successful as it is if it weren`t for computers, because movies these days require a lot of animations and use of graphics to create effects. So basically the whole universe is a computerized universe as it is right now. Even back in the late years of 1600 to 1800, the people saw that life was becoming complex and so they needed to create something that would help them solve the complex problems and mathematics so they wouldn`t have to solve them manually. And so they came up with calculators which could only add and subtract mathematical problems. And the more the technology grew the more computers became important in their daily lives to the present. Computers have changed man a lot. It has helped man to step in to the future. Though computers have been said to take away man power, still computers have managed to make the impossible possible. In the upcoming paragraphs I will be talking about how computers have impacted on different fields.C:Program FilesMicrosoft OfficeMEDIACAGCAT10j0315447.jpg C:UsersRahatAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5Q0IF2038MC900357275[1].wmfC:Program FilesMicrosoft OfficeMEDIACAGCAT10j0233018.wmfC:UsersRahatAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5LVY57DLOMP900315661[1].jpgC:UsersRahatAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5E5WK0490MC900090300[1].wmf IN BUSINESS FIELD In today`s life computers have impacted many fields such as the business fields. Many business organizations need computer to keep track of accounts, money and other stuff that they need. It has been noticed that business people use computers a lot both at their homes and at their working places. One may see that these people make pie charts and graphs that they use for presentations during business meetings where most of these charts were made by the help of computers. The business field uses computers a lot in their activities. C:Program FilesMicrosoft OfficeMEDIACAGCAT10j0233018.wmf Nevertheless, business organization now a dayà ¢Ã¢â ¬Ã¢â ¢s use online marketing to advertise and contact with their consumers from different parts of the world without direct contact. For instance in www.amazon.com, this is an efficient way of business since it does not limit the area of supplies and consumers. It is through the use of computers that they are able to perform these activities. IN ENTERTAINMENT FIELD Another area that computers have impacted is the entertainment area. It has been seen that most of the people love science fiction and action movies and those that have neat effects like Matrix or Harry Potter. Well the graphics and animations used in those movies were done by computers themselves. Most of the movies today use these graphics to make movie effects look realistic. For instance in Harry Potter where Harry has to fight dragons and big snakes, all those effects look real but they are not realistic and some movies where we see aliens, space ships, monsters or flying men. Some movies are even made by computers from top to bottom like toy story and wall E. Not only movies but also game consoles use computer animations like the Play Station, PC and Nintendo. And it has been seen that games made by 3D graphics have been big breakthrough in gaming. All thanks to the awesome computer graphics. Even the music industry has been impacted in its way. Since music editing and video making all require computers to create effects or edit videos. Thus computers have a great deal of effect in the entertainment industry today. IN EDUCATIONAL FIELD Educational field has been impacted by computers as well in its own way. Like in universities computers help students a lot with their assignments and presentations. For instance a student had to do a project on World Religions; he would use the encyclopedia to search for information. Even when presenting their works like for presentations one would use Microsoft power point and writing of essays would require Microsoft word. Even teachers themselves use computers as well. They use computers to keep track of grades or prepare notes and presentations for their students. Through servers/networks educational institutes can share and control resources, by connecting computer devices together which saves a lot of time and money. For lecturers it becomes easy when a lecturer is giving a lecture then students can just take note rather than printing out pages and pages of notes. Nevertheless e-learning is also a product of computer`s development. Thus computers have a great deal of importance in the educational field. IN THE MEDICAL FIELD This is one important field that computer have impacted. Computers help in hospitals and even in small pharmacies. Doctors and nurses use computers to make records on medication of patients and in what amount so they wouldn`t lose track. But in big hospitals computers are also used to keep records of every patient. They also keep records on medical bills and equipments. Nevertheless scientists need computers so they could find cures to different diseases that keep erupting every day. If it wasn`t for computers these cures wouldn`t have been found. Therefore computers are important since they help us maintain our health.C:Program FilesMicrosoft OfficeMEDIACAGCAT10j0315447.jpg IN SPACE EXPLORATION Computers have had a great deal of impact in this area. Computers help in designing the right kinds of equipments and ships that are used now a days for most exploration. For instance a large organization like NASA needs these kinds of machines for space exploration. In space, small errors or miscalculations can create serious problems that cannot be easily corrected. Computers provide faster and more accurate handling of data, both in planning a mission and in analyzing parameters during a mission. Without them, effective space exploration would be nearly impossible. This has proven to be successful since everyday huge deal of inventions and discoveries from these explorations, like life in mars. And now scientists are trying to find if there is another life form on other planets. Computers also help them to solve complex mathematics such as from which degree/angle should the rocket be launched, which would be quite difficult for humans to calculate.

My Personal Identity Essay -- Personal Narrative, Identity Essay
A personââ¬â¢s identity is shaped by many different aspects. Family, culture, friends, personal interests and surrounding environments are all factors that tend to help shape a personââ¬â¢s identity. Some factors may have more of an influence than others and some may not have any influence at all. As a person grows up in a family, they are influenced by many aspects of their life. Family and culture may influence a personââ¬â¢s sense of responsibilities, ethics and morals, tastes in music, humor and sports, and many other aspects of life. Friends and surrounding environments may influence a personââ¬â¢s taste in clothing, music, speech, and social activities. Personal interests are what truly set individuals apart. An individual is not a puppet on the string of their puppet-master, nor a chess piece on their masterââ¬â¢s game board, individuals choose their own paths in life. They accomplish, or strive to accomplish, goals that they have set for themselves thro ughout their lifetime. Individuals are different from any other individual in the world because they live their own life rather than following a crowd of puppets. A personââ¬â¢s identity is defined by what shaped it in the first place, why they chose to be who they are, and what makes them different from everybody else in the world. I feel that I have developed most of my identity from my own dreams, fantasies, friends, and idols. I am who I am partly because of my family, but mostly because of who I want myself to be. I will never be exactly what I want to be because of my family upbringing, but I can provide myself with opportunities to live a somewhat similar life. I would have loved to be brought up in a family that was into off-road racing, such as trucks, snowmobiles, an... ...far, education has had no real impact on the person that I am, but hopefully by the time I finish college, it will. I am very proud of the person that I have become. I have followed my own dreams, fantasies, friends, and idols to become the person that I am today. My family has influenced me as far as morals and values, my friends have influenced me in social activities, speech, and clothing, and my fantasies and idols have given me something to strive for in my life. Once a person takes the time to truly get to know me, they tend to see me as one of the greatest guys that they have ever met. I will continue to live my life for individual that I am while taking into other people and not doing anything that may negatively affect another personââ¬â¢s life. I am currently very happy with the person that I am and will continue keep myself happy until the day I die.

Waste Disposal
1. Advantages and disadvantages of landfill sites. Using Orgreave as a landfill site is a cheap waste disposal option for the local council. The site will look ugly whilst it is being used for landfill. Jobs will be created for local people. Dangerous gases are given off from landfill sites that cause local air pollution and contribute to global warming. Lots of different types of waste can be disposed of by landfill in comparison to other waste disposal methods. Local streams could become polluted with toxins seeping through the ground from the landfill site. The site could be re-landscaped and built on once it has been filled. This has happened nearby in Handsworth. Once the site has been filled it might not be able to be used for redevelopment as it might be too polluted. The gases given off by the landfill site could be collected and used for heating. The jobs created in the local area are likely to be low paid jobs. Waste transport costs will be reduced, as our waste will only have to travel a short distance to landfill. This will also reduce the amount of pollution caused by transporting the rubbish. The trucks delivering the waste to the site are very big and noisy. They will spoil the peace and quiet in the area and could also contribute to traffic congestion (traffic jams) in the local area. Local rubbish will be dealt with locally instead of shifting the problem to another area or country e.g. China. The gases given off from the site as the waste begins to decompose (break down) will cause the air in the local area to be smelly. 2. Problems of waste disposal * Waste is being dumped in the wrong culverts: the black and green culverts both have a mixture of food, metal, glass and plastic. * Animals (e.g. marabou storks and mongooses) get into the culverts and extract food and food contaminated burnable waste. * There is no separate place for disposal of non-burnable waste (metal and glass) ââ¬â this is currently mixed with food and burnable waste. * Some culverts are full and waste is spilling out. These problems result in a highly unsightly, unhealthy environment for visitors, residents, and wildlife 3. How is waste disposal being improved for the future? * Sustainable installation and upgrading of waste management facilities * Extending sewage networks * Set up agency to monitor waste * Classification: now classified into inert, non inert non hazardous and hazardous * The need for a landfill liner and geological barrier on the base and sides of all non inert non hazardous and hazardous landfill sites * The requirement that all waste is pre-treated before being land filled * The requirement to have Waste Acceptance Criteria (WAC) for all land filled waste * The banning of liquid, explosive, corrosive, oxidising flammable and clinical wastes * A requirement for a 60-year aftercare provision

Disaster Recovery
Disaster recovery is the planning and implementation of a process whereby a company can recover from a catastrophic information technology failure. The three main categories of disaster exposure include natural threads and hazards (including hurricanes, flooding, earthquakes and fire), technical and mechanical hazards (such as power outages, gas leaks, accidental or deliberate Halon discharges, or chemical spills) and human activities and threats (like computer error, loss of records, vandalism, sabotage or epidemic) (Rike, 2003).The goal of disaster recovery planning in information technology is to restore access to business data and system resources as quickly as possible, as well as to minimize data loss and physical resource loss. Disaster recovery must address each of the main categories of threat, assess the likely impact and the chance of occurrence of each one and plan reactions and facilities accordingly. Disaster recovery is not only important for the IT-based company, but for any company which is vulnerable to natural disaster or malicious attack.Proper planning of a disaster recovery framework will increase response time, minimize data loss and speed recovery and regained access to data and computing resources. Disaster recovery planning for information technology includes: data assurance with a proper backup and restore procedure; network continuity; intrusion detection and response; proper facilities planning including air conditioning, fire detection and control and environmental sensors; and personnel training in order to ensure proper response.A business's disaster recovery framework may extend beyond its information technology into facilities management, human resources and other operations. Disaster recovery is a relatively new facet of information technology planning which has rapidly become more important as businesses have become more dependent on technology resources. Many modern businesses come to a standstill without their technology ba se, and this can be devastating to the business. Rike (2003) noted that 93% of companies which suffer a major data loss go out of business within five years following that loss.However, according to Rike, many companies are unprotected from this danger ââ¬â two surveys noted that only 35% of small and midsize businesses have a disaster recovery framework in place, while only 36% of all businesses and government offices have such a framework. Disaster Recovery Case Studies One of the first discussions of disaster recovery in information technology occurred after the 1995 Kobe earthquake in Japan. Garland and Morimoto (1996) provide an account of the outcome of the Kobe University disaster recovery framework on their IT infrastructure, as well as the effects of the earthquake itself.The Kobe earthquake, referred to as the ââ¬Å"Great Hanshin Earthquake Disasterâ⬠, struck the Kobe area in the early morning hours of January 17, 1995. Aftershocks and fires worsened the damage c aused by the earthquake, cutting off communications and electricity to the region. Transportation routes were completely blocked due to collapsed roadways and damaged rail lines. The earthquake, which measured at 7. 2 on the Richter scale and left almost 5,400 dead as well as 400,000 homeless in its wake, was one of the worst disasters that have occurred in modern Japan.The university, where the authors were teaching at the time, lost two professors and thirty nine students, as well as all its laboratory animals. Data loss was extensive, and computing equipment loss was exacerbated by physical damage caused by falling furniture and books. The university's telephone and fax connections were completely cut off. However, despite the damage to the university's infrastructure and community, Internet connectivity was able to be restored within a few hours of the earthquake.The resulting email access (there were no extensive Web-based resources at the time) allowed students and staff outsi de communication, a means to reassure loved ones and provided a connection to government disaster recovery resources. University personnel also used cellular phones, a then-nascent technology, to connect to the outside world. Kobe University was using the best available technology at the time, which allowed for quick recovery of the lightweight machines.The IT personnel at the university noted specifically that the hardest-hit IT resources were the older-style, stationary, heavyweight servers and storage units, rather than the newer equipment which was designed to be moved and handled. Specific successes of the Kobe University disaster recovery included: use of alternate routes of communication, broadcast communication to all personnel involved (including students and staff), fast restoration of outside connectivity, setup of alternate email access points and gateways to continue to provide communication and the use of more robust, newer hardware resources.Some of the problems with the university's disaster recovery were lack of system-wide backup plan leading to widespread data loss, insecure physical premises leading to damage, including fall damage to computer equipment placed inappropriately close to other hazards and environmental system failure leading to the death of the lab animals. Because Kobe University is the first instance of formalized study of disaster recovery in information technology, there are a number of questions which arise from the planning and execution of the recovery.What are the priorities of the business or organization when planning? How do you put into place organization-wide policies, such as data backup, which reduce the risk of failure? How do you deal with facilities and functions (such as public utility infrastructure) that are out of your control? A more recent demonstration of the importance of disaster preparedness and recovery was Hurricane Katrina, in 2005.Chenoweth, Peters and Naremore (2006) analyzed the disaster prepa redness and recovery response of a New Orleans hospital during the hurricane and the flooding that followed. East Jefferson General Hospital, located in Jefferson parish, was one of three hospitals in New Orleans to remain open during and after the storm. The hospital planned for a two to three day emergency situation; staffers brought appropriate supplies for only a few days.There were over 3,000 people, including staff, patients and community members, as well as a handful of pets, sheltering at the hospital by the time the storm hit New Orleans on August 28. The hospital's IT staff worked quickly to move critical equipment out of harm's way ââ¬â they moved data center equipment to upper floors and PCs and other equipment away from windows, printed out hard copies of patient records, contact information and other vital data, and set up a hospital command post with PCs, telephones and fax machines for outside connectivity.The hospital itself did not sustain a high degree of phys ical damage in the storm, in contrast with Kobe University. However, the infrastructure of the city itself was virtually destroyed, with electricity, telephone and water cut off, roads blocked and food and drinking water supplies tight. The hospital was isolated from the rest of the world for over a week as external recovery crews worked. East Jefferson Community Hospital did have a written disaster recovery framework in place prior to Hurricane Katrina.According to Chenoweth et al (2006), the IT department had a hot site arrangement with SunGard; weekly backups of the hospital's data were stored in a local tape vault, occasionally retrieved for safe storage in SunGard's offsite facility in New Jersey. Unfortunately, the evacuation of the vault's staff left the tapes inaccessible. During the storm, the hospital lost first grid power and then generator power; communications were lost as the Bell South CO, then the onsite CO, and finally the hospital's Cox internet cable connection we nt down.The rapidly changing situation, according to the authors, forced a reprioritization of IT resources and efforts from internal systems maintenance to restoring and maintaining communication with the outside world. The IT staff found a usable dialup line and set up email access using some of the PCs on-site; they also leveraged spotty cellular service and messaging services to maximize communications, which allowed them to coordinate with rescue teams and officials and arrange for food, water and generator deliveries. The internal telephone system was also utilized to maintain communication throughout the hospital.A secondary concern to the hospital, according to Chenoweth et al (2006), was its employees; particularly, circumventing the normal payroll system, which was inaccessible, in order to provide funds to employees who were suffering high expenses due to evacuation. This was accomplished by using the Internet to provide a funds transfer to each employee approximating the ir last paycheck. Similar workarounds were created for accounts receivable, with employees manually entering charges and emailing them to the system provider for processing.The hospital's outsourced IT provider also had its own issues to deal with; it had to locate missing employees (which was accomplished within three days by using a broadcast approach of Internet connections and message boards and contacting family and friends of the staffers; this is in contrast to many other companies, which were still struggling to locate employees by November) and prevent employee burnout by arranging for relief staffers. East Jefferson Community Hospital's IT infrastructure was back up and running only a week after the storm hit, and began providing patient services immediately.Its disaster recovery framework, as well as quick thinking in repositioning the framework when it became clear that it did not match the profile of the disaster it was supposed to counter, was a clear factor in the hos pital's fast recovery and return to service. Following the experience during Katrina, the hospital's IT staff investigated its disaster recovery framework and cited a number of changes which should be made, including increased emergency communications capacity, maintaining high-speed Internet access and implementing an automatic switching mechanism should one generator go down again.Disaster Recovery Framework Design The experiences of Kobe University and East Jefferson Community Hospital clearly indicate the need for robust disaster recovery planning. While disaster recovery is not always a matter of life and death as it was in these two cases, it can often mean the difference between a company that recovers successfully and one that is driven out of business by a critical failure. How can a company begin to develop a disaster recovery framework, and how extensive does this framework need to be?Benton (2007) suggested that the disaster recovery framework must begin with a formal bu siness impact assessment. This assessment draws on the knowledge and experience of the IT staff and the CIO to determine what the critical pieces of IT infrastructure are for a given company. A business impact analysis (BIA) is a way in which the contribution or importance of a given business resource can be analyzed and expressed in dollars and cents terms, in order to allow corporate officers to determine the correct emphasis during disaster recovery.The BIA also includes subjective observations of the resource's importance, giving an overall view of the organization to the decision makers. The second piece of the decision-making process is the risk analysis. What kinds of disasters are likely, Benton asked, and how much damage are they likely to cause should they occur? Exactly how likely is a disaster to happen? Benton urged caution on this question; as he pointed out, the risk of being unprepared is potentially far greater than the cost of preparedness.Rike (2003) discussed the risk analysis that should be performed before beginning a business inventory analysis and disaster recovery planning. Risks should be analyzed in three different dimensions: the type of risk, the likelihood of the risk and the magnitude of the risk. Rike divided risk types into three general categories: natural threats and hazards, technical and mechanical hazards and human activities and threats. Rike noted that it is not always possible to predict some types of disasters, such as human activities, while some activities, such as common weather phenomena, can be planned for in advance.The third dimension of risk analysis is the magnitude of the potential risk. Rike identified three categories of magnitude: community-wide disasters, such as the Kobe earthquake and Hurricane Katrina as discussed above; localized to a building or a group of buildings, such as water leak or electricity outage; or individual, or only affecting a single organization, department or worker. A disgruntled w orker sabotaging data exemplifies this situation. Rike (2003) outlined a proposed schedule and method for designing a disaster recovery framework.The first step, obtaining top management buy-in and support, is critical in order to fund and implement the disaster recovery framework. It is also necessary for top staff to be informed of disaster recovery procedures because they will be ultimately responsible for its implementation. The second step Rike suggested was to establish a planning committee staffed with personnel from facilities, information technology and other critical departments who will be responsible for planning and implementing the policy. The third step in Rikeââ¬â¢s method is to perform a risk assessment and conduct a BIA.The risk assessment should include determining the type of risk the behavior is subject to and its likelihood, the consequences of each scenario, the estimated cost of each scenario, replacement cost of data, equipment and staff recovery versus d isaster framework implementation, and the potential risk of the worst-case scenario occurring. Rikeââ¬â¢s fourth step is determination of critical business facilities ââ¬â business equipment, connectivity through Internet and phone lines, internal phone system, fire and fumigant systems and other facilities required to continue to operate.This step also includes the determination of disaster recovery procedures and documentation, vital records and personnel. Step five is the procurement and preparation of disaster recovery facilities, including offsite storage facilities, inventory of critical documents, policy and procedure manuals, master lists of staff contact information, vendor information, account numbers and other vital information, and a review of security and environmental systems. Step six is preparation of a written framework, taking into account the information gathered in steps one through five.Rike recommended that a standard format and software package should b e used to write the framework, rather than a customized solution. The framework should then be reviewed on a frequent basis to ensure continued alignment with company business and goals as well as changes to potential risk. The final step in Rikeââ¬â¢s methodology is to test the written framework in order to make sure it is feasible. In order to begin developing a disaster preparedness framework, Benton suggested a company-wide IT inventory, detailing application, storage and server assets.These assets could then be ranked into categories depending on the importance of the business application and replacement cost of the equipment. There are two main ranking criteria. Recovery time objective (RTO) is the optimal maximum amount of time between disaster and service resumption. Recovery point objective (RPO) is the maximum amount of allowable data loss. Benton recommended a multi-tier system; at the top level should be no data loss and minimal downtime, or an RTO and RPO of close to 0, reserved for mission-critical services and business units that provide immediate revenue for the company.Business units should then be ranked in descending order according to their revenue generating potential and criticality. At its lowest level, Benton suggested that the RTO could be extended out to 72-96 hours. Rike (2003) identified key questions to use when conducting the BIA, including ââ¬Å"how would the department in question operate if online systems were not available? â⬠and ââ¬Å"what is the minimum space required for the department to operate? â⬠Benton prioritized two critical preplanning steps for disaster recovery.The first was data consolidation, or optimizing the protection of data by assembling all critical data in a single location for ease of backup and recovery. This can be established by use of a centralized file server in a small organization or use of a SAN or NAS scheme in a larger one. The second prerequisite, which can be more complicated than storage consolidation, is server consolidation. This step can be complicated because the performance profile of servers can vary, and processing and network access can vary between them. Benton further discussed the complexities of disaster recovery of data.Among the problems he noted are difficulties with logical consistency and order of recovery. If standard file backup technologies are used, these backups may not be logically consistent when they are recovered because they will be recovered to a slightly different point in time. Newer snapshot technologies can alleviate this problem, however. Another inconsistency issue is data replication, which may be interrupted when the write heads lose power. Finally, order of recovery will be important because some applications and servers will be dependent on other servers being restored first in order to maintain logical consistency.Benton also noted that disaster recovery should be maintained separately from periodic backups and arc hival procedures, because data storage procedures for periodic backups and archival procedures may not be adequate or appropriate for disaster recovery. Finally, Benton remarked that hardware designated for disaster recovery should be exercised in a non-emergency situation in order to ensure that it is properly configured and connected. Rike (2003) recommended a course of action in the event that the disaster recovery framework needs to be put into action following a physical disaster.The first step in Rikeââ¬â¢s method is to perform a damage assessment in order to determine the scope and type of damage, the size of the area affected and what assets have been damaged. Rikeââ¬â¢s second step is damage control by environment stabilization. In the event of physical damage, the damage can become permanent very quickly. Rike suggested that the physical environment must be stabilized by drying the air, removing water and soot particles, restoring air conditioning and whatever other cleanup can be performed.She suggested that material such as power generators, sump pumps to remove standing water, high-powered fans, plastic sheeting, absorbent materials and other cleanup equipment should be kept on hand in order to speed environmental stabilization. Once the environment is stable, Rike prioritized activation of the emergency team as defined in the disaster recovery framework, and then restoration and cleanup; this cleanup can in some cases be performed by business staff, but in some cases, such as a toxic spill or mold contamination, should be handled by specially trained professionals.While Rike discussed physical disaster recovery resulting from primarily natural or mechanical threats, Patnaik and Panda (2003) discussed data recovery from a malicious attack, addressing the human threat perspective. Malicious attack on data and application resources can come either from within the business (most often from a disgruntled employee) or outside the business (hacker s or industrial spies). As Patnaik and Panda noted, it is not necessarily possible to distinguish a malicious attack from a legitimate data transaction.According to the authors, requirements for protecting data from malicious attack include protection from unauthorized users, detection of hostile activities and damage recovery. Unfortunately, as the authors noted, in the case of a database storage system it is not always possible, even with these precautions in place, to catch all potential malicious transactions. This is particularly problematic when the malicious actor is someone who has trusted access to a system. If a malicious transaction is committed to the database, it is then seen as legitimate and may be propagated to other areas of the database through normal interactions.In order to prevent this spread, a quick recovery is required. Unfortunately, the authors noted, the size of database logs often precludes a fast recovery, due to extended periods of time spent accessing and applying the logs. In order to remedy this, Patnaik and Panda proposed a partitioned or segmented log solution which allows recovery of a malicious transaction to access only one of the log segments in order to perform recovery, rather than the full logs. This increases recovery time by an order of magnitude over applying the full redo log, according to the authors.Disaster recovery is a relatively inexpensive method of assuring business continuity in the wake of a natural, physical or human event or attack. The costs of not having a disaster recovery framework is, as Rike (2003) noted, extremely high ââ¬â 93% of businesses which suffer a major data loss go out of business within five years. The experiences of Kobe University and East Jefferson Community Hospital demonstrate the value of a disaster recovery framework, as well as the importance of examining priorities when deciding on the framework.While physical premises may be covered by insurance in some cases, the same is not typically true for data, institutional knowledge, continued business and personnel. In order to implement a data recovery framework, one can follow Rikeââ¬â¢s (2003) methodology, beginning with gaining the support of senior staff and the appointment of a disaster recovery planning committee, performing risk analysis, a BIA, and determining and putting in writing a disaster recovery framework and finally testing the framework to ensure its viability.These steps will help to protect the business in the event of a disaster, whether it is natural, mechanical or human in origin, and whether it is localized or community-wide. Research Proposal In order for a business to determine whether a disaster recovery framework is appropriate for their business, as well as to analyze the relative risks and costs of implementing a disaster recovery framework and replacing lost business assets and personnel in the event of a disaster. Following steps three and four of Rikeââ¬â¢s methodology will provide a determination of utility of a disaster preparedness framework for a given business.In order to perform this analysis, the assent of senior staff members should be obtained. This analysis can be conducted in the following manner. First, perform Rikeââ¬â¢s third step, that of risk analysis and assessment. This assessment should evaluate the potential threat to the business and its effects in three dimensions: type of threat (natural, mechanical or human), magnitude of threat (individualized, localized, community-wide), and likelihood (certain, likely, unlikely, extremely unlikely). Questions that should be asked during this risk assessment include: What is the natural environmental pattern of the geographic area? Is the area subject to earthquakes, flooding, hurricanes or other natural phenomena?â⬠¢ Are current environmental control provisions such as Halon systems and fire detection systems up to date? â⬠¢ How likely is attack by a human threat? Does the co mpany tend to have disgruntled workers, or no? How much access does any individual worker have to the data and application servers? â⬠¢ What is the replacement cost of data, equipment and staff versus the cost of disaster recovery framework implementation? What is the potential for the worst-case scenario to occur?After the risk analysis is complete, step four of Rikeââ¬â¢s methodology, determination of critical business resources, should be implemented. This step includes asking the following questions: â⬠¢ What is the minimum amount of servers, Internet connectivity, communications capacity, space, documentation, data and staff the company can continue to operate on? â⬠¢ Who is the critical staff? What is the critical data? How many single points of failure are there?Step four of Rikeââ¬â¢s methodology, the business impact analysis or BIA, is the final method of analysis in determining the benefit of the disaster recovery framework to an individual organization. The BIA examines each aspect of a businessââ¬â¢s function and determines which functions are critical to the businessââ¬â¢s continued operation, as well as which functions can be brought back online after the most critical operations are stabilized. This examination should include all facets of a business, including seemingly unimportant functions such as facilities management, janitorial access and human resources records access.Business functions should be ranked on a matrix of direct and immediate benefit to the business, determined by their immediate monetary value as well as subjective perceptions of importance. Using a combination of a risk and cost analysis to determine the likelihood of risk occurring and the cost of implementation versus non-implementation, a business needs analysis to determine critical business requirements, and a BIA to determine critical business functions, it will be possible to determine whether a disaster recovery framework makes sense for a gi ven business, as well as what type of disaster recovery framework should be implemented.It is the authorââ¬â¢s contention that disaster recovery planning makes sense for every business, and should be implemented at a level that will ensure business continuity and hasten recovery should a disaster occur. Customization of disaster recovery planning should be done using the risk, cost and business needs analysis to create a framework that will allow the business to secure its own interests in the event of a small or large disaster.No disaster recovery framework is perfect, and there can always be situations that remain unconsidered, as East Jefferson Community Hospitalââ¬â¢s experience showed. However, having an initial disaster recovery plan in place made it easier to reprioritize resource allocation when there were unexpected issues. As von Moltke remarked, ââ¬Å"no plan survives contact with the enemyâ⬠ââ¬â but that is no reason not to plan.
