A Piece of Peace Essay

The terrorist attacks on September 11th affected more than just the lives of those in people who were the direct victims of the attacks. An entire nation was victimized and the whole nation grieved for those who suffered in New York City. As the attacks occurred I sat in my high school English class and while the teacher taught I day dreamed. It was a typical Tuesday morning and to be truthful I did not ever hear her the first time she explained the tragic events that had taken place just moments ago. I heard the word â€Å"terrorists† and the fragments of statements like â€Å"hundreds died this morning when†. Then, I could only hear my heart beat in my ears. I watched my teacher turn on the TV. She flipped through several stations. I don’t remember what I saw but I can remember what I heard. It was the sound of people crying. Over the next few months, as a nation, we followed the story as did the world. I can remember President Bush attempting to comfort the United States and telling us America would be going to war for reasons that weren’t clear to me then and certainly aren’t clear to me now. Somewhere between the night of September 10th, when I was plotting how I was going to avoid school the next morning and the night of September 11th, I grew up. When I look back on that time in my life I am left with a single haunting thought – It is the pursuit of peace which leads to destruction. Even today, years after the terrorist attacks, people still talk about how that day changed everything. I agree, in some ways. It changed me and I became something new. It changed my family. It changed how American view other Americans and how we view the rest of the world. Americans have since the birth of the nation believed that their way was the best way. Americans were shocked to find out that people hated them enough to want to kill them. September 11th forced America’s to reflect on the military, social, and political actions of America and how they effected people of other countries. Perhaps American’s are not always in the right. For example, President Bush I gave weapons to the Afghan people to win a war against Russia. When the Afghan people defeated the Russian, Afghanistan was completely destroy. American promised them they will help rebuild but they did not. That is why the terrorist were able to come into the country and making a terrorist breeding ground. I don’t think that September 11th effects the way Americans conduct their lives daily. People who say it does are feeling the pressure of guilt. Society says we must not forget, and as Americans say we won’t. As a nation the citizens learned that there is a fine line between terrorist and freedom fighter- we are just afraid to admit it and seem unamerican. Those men who ran planes into building, killed Americans and killed themselves wanted only one thing – peace. They wanted freedom from the western world and choose to die. Just as we wanted independence from England centuries ago. In looking for peace they destroyed lives, families, and shook the protected ground the United States sat on. It made the country stronger but not smarter. I am anxious over the global discord and the cultural ignorance that seems to grow between the United States and the rest of the world. The problems in Iraq foretell and may spark future clashes with a number of civilizations in the future. Just recently I drove home from work and I flipped through different radio stations. I caught the end of Bob Dylan’s â€Å"The Times They Are A-Changing†. It’s funny because that is my mom’s favorite song and I had forgotten it existed. I still can hear her sing, â€Å"Come gather ’round people Wherever you roam / And admit that the waters Around you have grown /For the times they are a-changin’†, while she tinkered around in the kitchen way before anyone else got up. I don’t know that I ever really listened to the words before. Dylan knew and my mom knew things I was just beginning to. Dylan and my mom knew â€Å"there’s a battle outside And it is ragin’† and September 11th did shake our â€Å"windows† and rattled our â€Å"walls†. As a nation it’s citizens have no right to â€Å"criticize What we [you] can’t understand† and our â€Å" sons and [y]our daughters Are beyond our [your] command† (Dylan). Our soldiers fight a war for reasons no one really knows for America that would rather criticize them then help in country that does not seem to want peace. Dylan sings about the injustice in war and that we should not be afraid to speak our minds: Come writers and critics Who prophesize with your pen And keep your eyes wide The chance won’t come again And don’t speak too soon For the wheel’s still in spin And there’s no tellin’ who That it’s namin’. For the loser now Will be later to win For the times they are a-changin’. (Dylan) Bush wants peace but for his own reasons and through those reasons American soldiers are dying, and so are the Iraqi people. It is ironic that while those terrorists die nobly but ur soldiers die in such a cruel way. McKay writes in his poem, â€Å"If We Must Die,† that people should not die for nothing or by doing nothing. That death is inevitable, especially in war, but all people must fight for the things we want in this world and hold on to life and liberty as long as we can: O kinsmen we must meet the common foe! Though far outnumbered let us show us brave, And for their thousand blows deal one deathblow! What though before us lies the open grave? Like men we’ll face the murderous, cowardly pack, Pressed to the wall, dying, but fighting back! (Claude McKay) In the summer of 2001 I was lying in my hammock and I could see a butterfly in my backyard. I remember as a child learning that caterpillars itch and go into cocoons to find peace from that. Change in a way is a form of destruction. To be able to be someone new people have to give up their old selves and move past who they used to bee. When a child develops into an adult, he must give up his toys, his childhood beliefs like believing in Santa Claus. His childhood fantasies must be destroyed if he is to move on. In the years that followed September 11th I could feel myself â€Å"adapt to my new surroundings† (White Line 2). White, through the use of nature explores the scary nature of change: I have to shed my skin again Adapt to my new surroundings become another version of myself. The change within me does not happen overnight but through the evolution of my life (White) I was filled with American’s sense of patriotism and unity. The new American was like â€Å"the first fish that grew tiny legs† (White Line 8). Christine White’s poem, â€Å"Molting† reminded me that it was not just me that grew up, the United States did too. White’s point of view is that change is not a bad thing and is inevitable. Nearly every person around the country joined together as one united entity to pay tribute and homage to all the fallen heroes. There was a sense of harmony and peace. In way I think America, even those the terrorist attacks were tragic, knew that such an event was needed if we were going to â€Å"shed our [my] skin† (White Line 1) and become a stronger nation. As time goes by and my bad memories fade I remember America in it’s full glory. Watching the cumulative effect of humanity shining through the fire and smoke. I remember how many people spoke about the importance of peace and understanding. I wonder if there can be peace if Americans are divide both support and protest our soldiers in Iraq. The war over there caused a war here between Americans. It is the protesters protest protesters on both sides of the issues – each wanting peace in their own way. People who do not want our soldiers fighting in Iraq believe that they would be peace if America stopped butting into everyone’s business. People who are for the war in Iraq believe peace will only come after the destruction of all terrorists. In the end these protesters (on both sides) are destroying the morale and lives of people fighting in the Iraq war and are disgracing the memories of those that died. The price of peace is extremely high especially because Americans do not know if we can ever have it. I do know that â€Å"The line it is drawn The curse it is cast / The slow one now Will later be fast / As the present now Will later be past† (Dylan). I do know that America must hold her ground against the terrorists. Americans will not be tyrannized and forced to live like cowards. Even when we face â€Å"the murderous, cowardly pack, Pressed to the wall, dying, but fighting back! † (McKay Line 14). The American fight for freedom and peace has also managed to destroy our economy. Oil prices increased, the value of the American dollar decreased, and the stock market bottomed out. When Clinton was President the stock market was well over 10,000 after 9/11 it drop well under 8000. President Bush spent the Clinton Surplus on military, and it is just now in 2006 that the stock has become stabilized. I think that our economy will emerge from this disaster and become strong once again like it was before the attacks. In the pursuit of peace and destruction, people in Americans have finally understood their place in society and were back â€Å"in the sun† (White Line 10). Not as a not as a bystanders but an active and willing participants. Americans realize that there needs to be a great deal of change and those changes have started. American citizens encourage our â€Å"senators, congressmen Please heed the call / Don’t stand in the doorway Don’t block up the hall† (Dylan). And governmental officials are making changes. I think our nation needs to help a new generation of people realize that aftermath of that day when humans lives were lost and America’s unique humanity and independence was demonstrated. This generation’s hearts were opened and turned around in the wake of airplane crashes. On September 11, 2001 many people lost their lives because men were seeking their own personal peace. Daily our soldiers are destroyed one by one for the goal of peace. The American economy struggles because of the war for peace against terrorism. Americans fight Americans over whether we should be in Iraq or not which tears apart soldiers’ pride. Before that Tuesday in September, I never thought about life and death. I never considered the consequences of war and the denial of freedoms. Now that I am older, I realize that September 11, 2001 was not just pivotal point for me but America itself. Not since Pearl Harbor had the United States been unexpectedly attacked on it’s own land. Just as families pulled together so did the United States as a whole. As a nation we cried together and we healed together. To actually witness the attacks was life changing but to be part of the healing process was life affirming.

My Mom is My Hero

There are many other definitions of what a hero may be. Some may say heroes are noted for their â€Å"feats of courage or nobility of purpose, especially one who has risked or sacrificed his or her life†. Some may often see them as mythological legends, â€Å"endowed with great courage and strength, and celebrated for their bold exploits. † In my personal view a hero can be anyone of who you could relate to, and also more importantly stands up for what they believe. Does everyone have a hero? I don’t know but all I could say is that I do.And she is not found in a comic book or in the TV she is found right here at this little warm place that I call home. Who could this hero be? It’s my mom, Lucia Espinal. She is my hero because she works hard, is a family woman, and more importantly she believes in me. First, heroes are hard to find all because they are diligent workers. My mother is very hard working. She has worked her whole life to get where she is now. For many years my mom has been the only provider for this family. After dad left us home without a cent to feed us, she went out to work each day to support this growing family.Second, In order to be a great hero, one must be likeable and family oriented. Family is very important to my mother. When I think of my mom I think of how strong she is and how she has helped me throughout my 15 years. There hasn’t been a time in my life where I was going through a hard time and my mom wasn’t there, guiding me through it. My mom is a very selfless person. She is always sure to make sure other people’s needs are full-filled before hers are. She cares for her 4 children as if we were the most valuable thing to the world. To her, we are the most valuable thing in the world.Furthermore, my mom is my hero because she was always there for me when I was feeling down and out. She would try to cheer me up and she usually did. She knew what kind of medication to give me when I was not feeling well or when I was hurt. My mom is my hero because she has been only one who stays when the people I think are my friends leave. She is my hero because she has always been there just in case u needed someone to talk to and she would always listen to me. My mother is my hero because she is hard working and cares for her family.

Critical review of a research paper from the literature Essay

Orthotic devices, though very useful in treating lower extremity injuries, have become very expensive, which makes many patients be unable to afford them. This proves to be a challenge to the many patients in need of these healthcare services. As a result of this, semi-custom alternatives were introduced in the market in order to act as alternatives to successful treatment of these injuries (Zifchock and Davis 2008: 1287). The purpose of this study was to evaluate the success of these devices, especially when treating people who have extreme cases of either high or low arches. A research was subsequently carried out in a laboratory which was equipped to analyse the comfort levels and rearfoot kinematics of the subjects. These subjects were thirty seven in number and were subjected to various tests, which included their behavior under semi-orthotics, custom orthotics and no-orthotic conditions. The findings of the study showed that both semi-orthotics and custom orthotics had reasonably high success rates in the reduction of excursion and eversion velocity. The custom orthotics had a higher success rate in reducing the eversion excursion. However, the semi-orthotics realised higher success rates in comfort among high arched subjects, especially in the arch and heel regions. Generally, the research findings proved that the semi-orthotics were reasonably practical alternatives to custom orthotics in terms of controlling the rearfoot motion and comfort. Critical review. The authors begin the paper by explaining the success of the foot orthotics, which they place at 75%. They also explain the uses of these devices with regards to correction of deformities, and they explain that the devices are used in extreme problems that occur in the lower part of the body. Such areas include the Achilles tendonitis and the anterior knee. The authors further explain the reasons behind the success of these devices, and their prohibitive costs which make many people be unable to afford them. The authors in this case have discussed a lot about the orthotics but have not really defined what they are. In fact, a lay man, may have no idea of what the subject of the study is. The authors should have began by explaining that foot orthotics are special devices that correct or support musculoskeletal abnormalities or deformities, that occur in the lower parts of the human body, such as the legs (Advanced Orthotic Designs 2008). They should have explained the nature of these devices through the use of a diagram, if possible. The authors further explain the prohibitive nature in the cost of these orthotic devices and go further to give the price range, which they place between $100 and $400. The authors must be commended for giving the price range, since it gives the readers of the article an insight of how affordable these devices are. However, the authors may have gone further and explained the reasons for this large price range and explained which types of orthotic devices cost $100, and which ones cost $400. The semi-orthotics are thereafter introduced to the article, and the authors explain how they are made. They explain that moulds are created based on the measurements of a person’s foot, and also explain the cost benefits that are gained through this alternative. However, since the authors have not described how custom orthotics is developed, it is difficult to use the creation process of semi-orthotics described by the author to understand the difference between the two. The authors go on to describe the differences that people with excessively high and low arches face. They also go into detail explain the purpose of the study, which had been briefly discussed in the abstract page. The next phase is the introduction of the research methods. Research Methods. The research used a priori analysis, which only requires 18 subjects. The researchers used 37 subjects; 19 low-arched and 18 high-arched. It is clear that the number of low arched subjects were higher than the number of high arched subjects. Since the research tests the subjects in terms of low arch and high arch characteristics at this stage, it is fair to say that they should have both been given a level ground when testing these characteristics. The number of subjects should have been the same, in order not to introduce bias in the experiment (Yin 2003: 62-67). The fact that the low arched subjects are more increases the probability that testing them will produce a lesser margin of error, since the sample size is higher. The average age of the subjects was 23. 6 years, 66. 5 kilograms in weight and 1. 7 metres in height. There were 20 females and 17 males. The number of females is greater than that of males. Since the genders are being tested for similar characteristics, they should have been equal in number so that any conclusions made in terms of gender can be accurate. Since females are more, it means that there will be a lesser margin of error due to a larger sample size, as opposed to their male counterparts. Any subjects who had injuries did not take part in the experiment, which is a good decision, since the injuries would have affected the results of the research. The measurement of the arches using an arch height index system of measurement is commendable since it is a very accurate system of measurement. Subsequently, measurements of the feet of these subjects were performed, and the plaster casts created by professionals. After being developed, the subjects received the casts without knowing if they were custom or semi custom. The decision not to inform the subjects was wise, since it would prevent bias or manipulation of results (Tansky and Heneman 2006: 123-125). However, the authors do not mention the checks and balances which were developed to prevent the manufacturers from manipulating the manufacturing process, which would have enabled them to manipulate the results. This is very important information which the authors did not give, since custom manufacturers are likely to manipulate the results to favour them and vice versa. Processing of data was done through the Visual 3D software, mixed ANOVAs amongst other means. Statistical significance used was 0. 05. The authors should have mentioned the various strengths and weaknesses of the data processing methods and other hardware and software used. The conflict of interest notes at the end of research briefly explains some of these concerns. Results. The general results indicated that both the semi orthotics and the custom orthotics considerably reduced excursion and eversion velocity. The custom orthotic significantly reduced eversion velocity in comparison to the no-orthotic conditions. This was similarly observed in the semi-orthotic conditions. When comfort was analysed, the findings revealed that the semi-orthotic devices significantly improved comfort in the heel region, in high arched individuals. These findings reveal that the semi custom orthotic is just as effective as the custom orthotic. However there is a lack of clear information on the exact differences between the two, in terms of superiority. It is not disclosed if indeed the custom orthetics are superior to the semi-custom orthetics. The major aim of the experiment appears to be the measurement of performance of the custom orthetics and the semi-orthetics, in relation to the characteristics of the subject of the study. There is very little comparison between the two types of orthetics, on their own. We cannot therefore tell which is superior, and for what reasons. This can be said to be one weakness of the study. Methodology. The authors used case studies, academic journals as sources of information. These methods of collecting information can be classified as secondary sources of information. This is because they are obtained from research carried out by other people. According to Gall et al. (2003: 78-83), advantages of using academic journals include the fact that they more reliable than most sources of information, since they are written by scholars who are experts in the field of study. This makes the probability of making errors or having bias reasonably low. They can also be accessed at low costs over the Internet and cover a wide range of topics. Finally, according According to Kothari (2005: 53-62), they are useful when carrying out exploratory studies, where there is limited information on the subject of the study. However, just as other sources of secondary data, there are limitations of using these forms of data (Maxwell 2000). The first weakness of the use of secondary sources of data is the inability to seek confirmation or further explanations from the authors of the work. This is due to the reason that unlike some methods of collecting data such as observation, there is a very low possibility of seeking audience with the authors and getting further explanations on the topic of study. According to Steinberg (2004), another weakness is that the researchers face the possibility if relying on biased information when conducting their research, which may distort their findings. If the original author was biased when conducting the research, then relying on the same information may lead to inaccurate findings and conclusions. However, it has been seen that the possibility of this risk has been reduced through the use of academic journals when conducting the research. Finally, the authors must be commended for conducting a comprehensive research, judging from the vast number and credibility of the references. They used over twenty references, most of which are academic journals, which enabled them to acquire a detailed report on the subject of study. Conclusions and recommendations. The overall research paper has been seen to have relied on a comprehensive research, judging from the validity of the references. The research method was also consistent with the expectations of this type of experiment. However, there were a few flaws that needed to be addressed. In analyzing the format of a research paper, it becomes clear that the hypothesis is missing from this research. The statement of hypothesis is absent, and though the authors explain the intention of the research, the lack of it may make some people question the authenticity and validity of the research paper (Creswell 2000: 52-58). Another weakness that was discussed involved the use of secondary sources of data to obtain information. The authors did not present these weaknesses to the readers, or other people who will rely on the same research when conducting future researches. In future, they should explain the weaknesses of the studies in order for readers to know the risks involved when relying on the same (Hinkel 2005: 239). In summary, the research can be said to be a success, since the weaknesses are far much lesser than the strengths of the research. Bibliography. Advanced Orthotic Designs. 2008.

MGT509 - Human Resource Management Mod 1 SLP Essay

MGT509 - Human Resource Management Mod 1 SLP - Essay Example It is no secret that recruiting, selection and onboarding are some of the most important processes for bringing in new talent in an organization. Companies spend a lot of time, money and energy into selecting and hiring the best recruits and can only hope that they will stay through the orientation programs and beyond and be a good fit with the organizational culture so that they can be contributing to its goals in the shortest time possible. In some ways, the success of the hiring program also depends to a great extent on the investment of time and energy in planning these aspects. As much as candidates try to show organizations that they are the best talent available, the organization also should try to show potential employees that they are the best employers. Coca Cola should know, it has over 100 years of experience and is a global enterprise having the world’s most recognized brand. As explained, I interviewed Miss Ceree Eberly, Human Resources Director for Coca Cola, USA. It was a short telephonic interview, but I think I got what I was looking for. She put me in touch with another HR representative who answered most of my questions on the company’s recruiting, selection and onboarding processes. One of the problems that HR is facing regards the verification of details on the forms and resumes of potential candidates. Like their Face book and Twitter profiles, resumes of candidates may be highly embellished or inflated with experiences and skills that they never had or used and roles they never played. The second difficulty is that candidates give up too easily during the hiring process and are frustrated because of current economic conditions in the USA. The company understands that this is partly because of post-recessionary trends seen in the economy, but society will have to adapt. They want candidates that are skilled and confident and see the job as a career, not just a stepping stone to another organization (SIOP, 2002). The third issue

Astronomy - Essay Example Yes, this makes sense because its authenticity can be determined by the high degree of accuracy with the use simple methods adopted since time in memorial. With the help of modern technologies like the Magnetic compass or Polaris (Northern star) the cardinal point will easily be identified. The main purpose of this site is to help people understand the Whole set up of Astronomy. It begins by focusing on the motion of the stars. These are artificial and fascinating natural objects that continue to illuminate light in the universe. As a result many people all over the universe have been wondering what these stars, how far and their arrangement in the sky. These intimate questions have led to emergency of Astronomists who can help people try to understand what is happening in the universe. Unlike the ancient people who intimately familiarized themselves with night sky the modern people do not have that time thus the need for assistance from the specialists in sky matters. It is also important to note that the as the stay stars move in the sky they maintain the same pattern hence prompting the specialists come up with constellations. As far as astronomy is concerned there are only 88 official constellations recognized by the astronomers. In order for one to carefully understand this arrangement the study of sky motion applet comes in handy. The distance between the two points in the sky can only be estimated by measuring of angles. This is done by measuring the two imaginary lines that are always seen running from the eyes and the two points. In order to understand the motion of the sky the ancient people had to come up with a mechanical model that would aid in clarifying this movement. The logic behind this is that all stars are entangled on a huge rigid celestial sphere that engulfs the earth and rotates around after every 23 hours and 56

French colonialism in Tunisia why did the french want to colonize Research Paper

French colonialism in Tunisia why did the french want to colonize Tunisia - Research Paper Example After the exit of the Ottoman Turks from Tunisia, major European powers were involved in a contest as to who would occupy the North African country. The French had to surpass two other European powers, in order for the former to establish its control over Tunisia. Both the British, Italians lost to the French in the occupation and gradual colonization of Tunisia. Accordingly, this essay will seek to establish the factors that led to the French occupation and colonization of Tunisia. Among the possible reasons for the French interest in Tunisia could be economic gain. At the time France was colonizing Tunisia, the latter was in a serious financial predicament, owing to numerous European debts2. Did France stand to gain economically by colonizing a financially weak country? On the other hand, Algeria, already a French protectorate and its proximity to Tunisia was of significance to the French colonists3. We shall also consider that maybe the French wanted to colonize Tunisia so as to i mpose French culture on the Muslim-dominated country. A final factor that could have motivated France to colonize Tunisia would be the need for the former to re-establish itself as a key power in global politics. The only way for France to achieve this imperialism would be through amassing as many colonies as possible. The topic on the French colonization of Tunisia is very intriguing. This is based on the fact that Tunisia is a country that borders the Sahara desert, the largest dessert in the world4. The leaves one wondering what could be so appealing about Tunisia, in order for it to be a centre of interest for three European powers. Particularly, why would France, a country recovering from major losses in Europe such its crush in the Franco-Prussian war want to colonize a country in economic crisis? France was willing to forego its interests in Cyprus to the British, in exchange

MGMT Essay Example | Topics and Well Written Essays - 250 words - 1

MGMT - Essay Example The transition from a senior Finance student to a young professional in a reputable organization is a challenging process. The preparation process for this big change involves searching for reputable companies that have programs for absorbing fresh graduates. The search led to a chance in a reputable financial institution that is willing to hire me once I finish my final year. It also entails analyzing factors like shelter and the most suitable area in terms of cost and access to essential infrastructure. Therefore, it is necessary to prepare some little funds to help in securing shelter and food before settling in the new job. The change signifies a big career development because it is the step sets a student on a path to achieving big goals in life. The greatest personal challenge in this change is the fact that I have to meet new people and adapt to a new environment. The uncertainty associated with success makes the process hard to manage. The greatest organizational challenge is fitting into new teams and forming good relationships in the company. I am not sure of many things, which makes it difficult to prepare for the first day when I get to meet everyone. It would take time to form frigid friendships. The achievement of my goal to become an established professional can be hindered by organizational issues like the lack of facilitating factors, ambiguity, and lack of teamwork. An organization that has no framework that supports young graduates makes it difficult to get a practical sense of being a Finance professional. I will propose for the organization leadership to start programs that prepare senior students on adapting to the professional world after school. The achievement of my objective to become an established professional will be an addition to the organization. The suggestion to start programs to recruit senior students provides the organization with a chance to get the best talents. I will

Terminal Objectives Program Philosophy in Managed Care Essay

Terminal Objectives Program Philosophy in Managed Care - Essay Example George Halvorson and George Isham, MD wrote an interesting piece describing this imperative need for managed care. Mr. Halvorson, to his credit, has two basic steps worthy of following, which will help what is now seen as an ailing health care system. Those two steps are creating overall care flow charts assigning accountability for each step in the care process and also devising a system supporting improved medical care in relation to each step in this process. The fact that managing health care has to keep pace with the changes in health care itself must be addressed. This must be addressed in the fact that in order to manage health care risks we must have a link between systematic improvement for care and payment for that care. The work managed in the courses pursued would bring a realization that is mirrored in the writings of Halvorson and Isham in that; one thing that must be done is the re-engineering of health care systems. The reason, integration, a method that integrates all the elements of health care into a manageable formula must be considered in order to be of benefit to health care and to the patients which it serves. Today's system hampers the most effective methods of health care delivery at all levels.

But if one is pulled back into reality, with the grimness of the world that human beings have created for themselves, one then is thrust to the question of justice, of equality, of liberty, of rights, and of freedom.  Ã‚   And for this very reason, the European Convention for the Protection of Human Rights and Fundamental Freedom and its Eight Protocol came into inception.Europe ravaged by the atrocities of the Second World War had become the living witness of the extent of the possibility of the madness that could be inflicted by man to other men.   Thus, the man-made catastrophe – genocide - had spurred various leaders of Europe to come together and create a treaty.   A convention that will have for its undertakings â€Å"the promotion or encouragement of respect for human rights and fundamental freedoms for all without distinction, and to take joint and separate action in co-operation with the Organization for the achievement of these objectives.† Together with this sad and horrifying experience of Europe is the fact that during the creation of the convention, Europe is â€Å"ideologically broken,† because during that time the â€Å"ideological conflict between Eastern Europe and Western Europe† was as real and as palpable as any concrete human experience.   With these two reasons acting as the primary motivators and ethos, Europe had created the European Convention for the protection of Human Rights and Fundamental Freedoms and its eight Protocols. This convention was â€Å"signed on November 4, 1950† and â€Å"entered into force on September 3,1953†.It is in this light that this paper is being pursued - to be able to shed light into the question of liberty as it is elucidated and clarified in the â€Å"European Convention for the Protection of Human Rights and Fundamental Freedoms a nd Its Eight Protocols.†Ã‚

Cost benefit and economic approach related to health care services Research Paper

Cost benefit and economic approach related to health care services system - Research Paper Example Globally, there are certain common problems which are faced by the health care organizations. In subsequent paragraph, a brief look has been given upon the overall issues which prevail in the health care units globally. Issues in Healthcare System The health care system is facing serious problems globally. People’s health care needs are not being met in an adequate manner. The reason is there are countless cases of illness and diseases each day. Fortunately, there are also numbers of solutions available to deal with these day to day problems. According to The Centre for Health Design, (2001), the most common problems which are faced by the overall health care sector are: Issues related to Patient Care Issues related to patient satisfaction Issues relating to accommodating innovation and change Issues related to operational efficiency Environmental Impact Responding to uncertainties. (The Centre for Health Design, 2001, p.4) In order to resolve these issues, a certain policy fr amework has been designed which can assist in solving such critical yet important issues. The policy framework designed to meet these problems is discussed in subsequent paragraphs. Policy Framework for Improving Healthcare System According to Bradley, Pallas, Bashyal, Curry and Berman (2010), a framework has been designed to ensure financial protection and adequate access to health care systems. It also strengthens the delivery systems in order to serve vulnerable people. Six factors determine whether the goals at organizational level are achieved or not in order to enhance the level of performance. They are: i. Quality ii. Efficiency iii. Utilization iv. Access v. Learning vi. Sustainability Quality Maintaining the required level of quality is the foremost requirement for healthcare systems. Improper quality can endanger the valuable life of patients. In order to maintain quality, it is essential to keep track of the quality in three major areas, they are: Clinical quality Patient experience Management quality There are several measures required to be taken care of for these areas. By evaluating the performance of these measures, it can be determined whether the quality is up to the mark or not. These measures include avoidance of medical errors, level of satisfaction of patient, availability of medical supplies, adherence to clinical parameters and medical records system. Efficiency Efficiency is defined as the way by which an organization utilizes its resources to meet the demands. Three measures which define the level of efficiency of a health care system include: Number of patients or patient volume Ratio of staff to service Ratio of cost to service The above mentioned measures can define the level of efficiency of a health care system. It can be determined by observing key indicators like health workers or nurses which are available for each bed or visits of outpatients or inpatients per day, per health worker or per bed. It should be borne in mind that it is not necessary to allot maximum number of nurses to each bed in order to meet the benchmark efficiency but in essence what it means is that the number of nurses available must not be less than the number of patients or number of beds. Utilization Utilization can be measured by: Patient volume in regards to capacity Patient volume with respect to the population of health characteristics. The key indicators which can measure the level of utilization are visits of outpati

Compare and contrast Essay Example for Free

Compare and contrast Essay Often adults feel the need to say â€Å"When I was your age† or â€Å"Things were different back then when I was a young, how things have changed since then.† But what exactly has changed? Although, there are some very obvious differences, there are still some similarities between generations that remain the same. Change, a small word, yet so powerful, frightening yet so embracing Change is inevitable. Frightening feelings can arise when one hears the word change because something that is so accustomed to them from a daily routine or even to new fashion styles, are being changed, resulting in bitter feelings towards the new product, or in this case the newer generation. If really thought about the people of the past bring out the people of the future. The gap between generations is huge, two very different types of people, yet both seem to be so alike. Much like today, racism flooded the streets in the 1960’s. Racism in the 1960’s was a decade of war, between white and colored people, that still today has not been put to an end. Propaganda played a huge role in the influence of white people not liking the colored people back in the 1960’s, but has there really been any difference in today’s society? 50 years later, the people of America still continue to feed off of these allegations from the 60’s that trying to change this issue has almost become impossible, and permanent. President Bush, in the summer of 2003, made a five day trip to Senegal, Africa, where many Africans once passed before being herded onto slave ships. He made comment and it said the following: â€Å"My nation’s journey has not been easy and it is not over. The racial bigotry fed by slavery did not end with slavery or with segregation. And many of the issues that still troubles America have roots in the bitter experience of other passed times.† He clearly states that the problem is acknowledge yet â€Å"undermining any effort to deal with the problem.†(Keeanga-Yamahtta Taylor) One similarity between today’s generation and the past generation(s) is racism still exists. Of course in today’s world, money truly does make the world go round. In this generation and in past generations, everyone was money hungry and still continue to be. But it’s imperative to be money hungry, because without that desire, we would not have what we have today. During the 1960’s the United  States practiced its longest continual period of economic development in history. America’s overseas investments increased to $49.2 billion dollars by 1965. After World War II the US economy improved even more and more leaving less to worry. Americans were out getting jobs because inflation at that current time was stable and corporate profits were also at a high. Unemployment rate was at 1.4 percent, during the winter of 1966 the economy was great, it the actual growth was 9 percent to be exact. This gave President Johnson an annual dividend of $4-5 billion in extra to spend. Just like back in the â€Å"baby boomers and generation x† period, today’s are also money hungry. Teenagers are starting to work harder and harder for their money leaving them the opportunity for a vast area of expertise in the work field at a young age. Parents encourage their kids to get jobs so they know what responsibility is and that you have to earn what you want by working for it, resulting in a money hungry society. Yet, today’s economy is not doing as well as the economy in the 1960’s, leaving that as one of the differences between now and then. Generation Z (1995-2007), contain individuals who more self-expressive, whereas, generation X (1960-1985) are to themselves (Isacosta’site.) Many would argue that one of the reasons why this current generation is â€Å"wild† but what is failed to realize is that people in the generation x era raised us to be this way. Children who were born from 1995-2007 are not responsibly for the way they act because they were raised to be that way. It is thought from a young age to talk about our feelings and express what exactly is going on because we are trying to stay away from being depressed, conservative and uptight like generation x. This comes around full circle, to blame the children of today’s generation for the way they were raised it pathetic. Back then girls had to wear turtle necks, and skirts below the ankle, there were no such thing as showing your shoulders, and now girls where crop tops and short shorts. Women weren’t allowed to question anything, whatever was said by your spouse it what had to be followed. The people of this generation found their voice in society and won’t settle for anything they do not deserve. As much as people want to think things are completely different from these  two generations, they fail to see that some things remain the same. Change happens more than the regular human can realize. There is change all around this world, from the moment one wake up to the moment one falls asleep. Change cannot be stopped, paused or regretted. Moving forward and embracing it is the only way to feel at ease with it. Yet, the general populations fail to realize that there are some similarities, racism and money hungry individuals still ponder the streets of our nation and will continue until change occurs. Although both differentiate in self-expressiveness and conservative aspects, together, unknowingly make change happen. Works Cited Adams, Katie. Generation Gap. Investopedia. N.p., n.d.

What are that iteration methods compare different iterative method?

What are that iteration methods compare different iterative method? What are that iteration methods compare different iterative method? What are the iteration methods? An iterative method is a powerful device of solving and finding the roots of the non linear equations. It is a process that uses successive approximations to obtain more accurate solutions to a linear system at each step. Such a method involves a large number of iterations of arithmetic operations to arrive at a solution for which the computers are very often used in its process to make the task simple and efficient. Iteration means the act of repeating a process usually with the aim of approaching a desired goal or target or result. Each repetition of the process is also called iteration and the results of one iteration are used as the starting point for the next iteration. For example, to solve the quadratic equation we may choose any one of the following iteration methods: a0x^2 +a1x+a2=0 a) Xk+1 = -a2+a0xk^2/a1, k=0,1,2 b) Xk+1= -a2/a0xk+a1,k=0,1,2- Types of iteration methods: Based upon the number of initial approximation values iteration methods can be divided into two categories: Bracketing iteration methods Open end iteration methods Bracketing iteration method: These methods are also known as interpolation methods. Under these methods we start with two initial roots that in bracket, then systematically reduce the width of the bracket until the desired solution is arrived at. There are two popular methods under this category: Bisection method Regular_falsi method Open end iteration method: these methods are known as extrapolation methods. Under these methods we start with one or two initial roots that do not need the bracket the root. These methods are various types: Netwon_raphson method Secant method Mullers method Bisection, regular_falsi and netwon_raphson methods are under root finding algorithm. Root finding algo: A root-finding algorithm is a numerical method, or algorithm, for finding a value x such that f(x) = 0, for a given function f. Such an x is called a root of the function f. Iteration method is obtain the initial approximation to the root is based upon the intermediate value theorem. This theorem is states that: if f(x) is continuous function on some interval[a,b] and f(a).f(b)

Ethical Hackers And Ethical Hacking Information Technology Essay

Ethical Hackers And Ethical Hacking Information Technology Essay The Internet and the other information systems are acting a vital role in organizations today. More and more organizations have become depend on network services completely of partially. So, a single failure of the network can cause severe losses to the organization. However, due to this huge demand of Internet and network services, computer security and the serious threats of computer criminals have comes to the foreground. Computers around the world are systematically being victimized by hacking attacks every day. Most of the attacks are very organized attacks and the attackers are very well understood about the general system vulnerabilities. So if they found any of those vulnerabilities in a system, they might be able to steal everything they want from the system and completely ease their tracks within even in less than 20 minutes. That might be a huge loss for the company in term of money and reputation. Thus to avoid these kind of attacks companies should have to employ a mechanism to Identify vulnerabilities in networks, applications and systems before they can be exploited. Generally, this is the job of an ethical hacker. Ethical Hacking and Phases Ethical Hackers and Ethical Hacking An ethical hacker is a security professional who helps organization to take defensive measures against malicious attacks and usually the process he doing to find those vulnerable point is called Ethical Hacking. Sometimes this is also known as Penetration Testing or Intuition Testing. In this case, the ethical hackers are getting into the minds of computer criminals; think like them to find about innovative ways the hackers may use to get into the systems. Then organizations can take required actions to avoid those vulnerabilities. It has identified that the almost all computer systems have vulnerabilities that can be exploited by a hacker to come to do damages. This can be due to an unpatched application, a misconfigured router or a rough network device and it will be not able to detect unless penetrate the networks and assess the security posture for vulnerabilities and exposures regular basis. As the hacking is a felony in most of the countries, ethical hackers should only operate having required permission and knowledge of the organization that they are trying to defend. In some cases, to check the effectiveness of their security teams, an organization will not inform their teams of the ethical hackers activities. This situation is referred to as operating in a double blind environment. To perform productive penetration testing, the ethical hackers who are going to conduct the testing must have to have variety of in-depth computer skills. They should know how to look for the weaknesses and vulnerabilities in target systems and need to have the knowledge of the tools a malicious hackers use on system hacking. However, because not everyone can be an expert in all the required fields that an organization uses, such as UNIX, Windows, Linux, and Macintosh systems; usually ethical hacking is conducted by teams whose members skills complement each other. Generally, there are three types of ethical hacker classes. This classification is done based on the hacking purpose of the hacker. Black-Hat Hackers Are the individuals who has the necessary computing expertise to carry out harmful attacks on information systems. They generally use their extraordinary knowledge and skills for personal gains. The black-hat hackers are also known as crackers. Gray-Hat Hackers Are the individuals with a split personality. At times, this individual will not break the law and, in fact, might help to defend a network. At other times, the gray hat hacker reverts to black hat activities. Thus we cannot predict their behaviour. White-Hat Hackers Are the individuals who usually have exceptional computer skills and use their abilities to increase the security posture of information systems and defend them from malicious attacks. These individuals probably are an information security consultant or security analyst. Why Ethical Hacking is need to perform Although many people know hacking as a horrible thing, most of them not think that they would not be hacked. But this is not the real situation. Almost every computer system has security breach that the haceks could come in and for security purposes these vulnerabilities need to avoid. One of the most important reasons for ethical hacking is to find those security leaks in an organization network. To do this, companies can hire security experts who have great knowledge on cyber security and trained as ethical hackers. So they can use their knowledge to hack into the systems to find insecure areas. Then the company can take necessary actions to secure their networks easily. There are two kinds of security leaks that an ethical hacker can identify. Hacking in to systems to steel data If a company compromised with this sort of attack they will lose not only the information or money, they will lose their reputation as well. So that might be cause to lose their customers as they not feel their personal information and data are completely safe. Leaks allows to compromise to Viruses If the company network compromised into viruses, it will allow shutting down entire network in just minutes. More than that, some viruses are able to perform harmful activities like data deletions. So the company may lost important data. Thus to improve overall security posture and avoid intellectual property thefts, regular ethical hacking practise is very critical in an IT company. More importantly, that will help save company money in millions and will build the reputation as well. Also as this system penetration is performing, thinking with a mindset of a hacker who tries to get in to the system, the companies can completely rely on professional ethical hackers reports to adjust the company security posture. Framework of Ethical Hacking In order to complete ethical hacking processes successfully, ethical hacking professionals have introduced several phases to follow up. In the there, they have break down the complete process in to several phases and generally both malicious and genuine users following that methodology. Following diagram illustrates those steps and it has described in detailed below. Anatomy of hacking Source: http://www.twincling.org/twincling/slides/ethicalhacking.pdf Reconnaissance This is the first step of any hacking attempt and generally the attacker tries to gather enough information as much a possible about the target system. This process also knows as foot-printing. In may gather information on areas such as determining the network range, identifying active machine, finding open ports, detecting operating systems. There are two ways reconnaissance is performing. Active reconnaissance: Is the process of live exploration of the system to find about the information such as running operating systems and services, open ports, routers and hosts. Passive reconnaissance: This involves monitoring and finding information or clues on the network using network sniffers or other mechanisms. The information can be domain names, locations, contact numbers etc. Sometimes this involves mechanisms such as searching through organizations or persons discarded materials. Following are some of clever ways or the tool, that reconnaissance can be perform against a target network. Using Google This is the most common and efficient way of finding information about a company. As the Google is the most common search engine using in the Internet, Google can be use to find publicly available information about target system. Sometimes, even though the company has removed the data from their web sites Google will be able to provide information from its caches. Thus Google can be use to begin the reconnaissance process. DNS Information tools The next best way to get information about a company is their domain name. If you know the domain of a company rest of the information such as their IP address, contact information and locations can be find easy using DNS tools. For this purpose, most common command line tools are whois and dig and they will show above DNS information in text. But the web sites like www.dnsstuff.com, www.samspade.org, www.geektools.com and www.easywhois.com will provide same information in more user friendly way. Those tools have various options and can provide information quarrying by the IP address or domain name. Also the command nslookup will map the domain name to the IP address or vice-versa. Arin Arin is a very well known web based tool to find network ranges which a company holding. Just entering a single IP address of the range ARIN can give the whole network range the company owns. Social Engineering After knowing the basic information about a company, the best way to get know more information about the company is performing social engineering. In here, hackers trick people into revel information by themselves. The common way is calling or meeting employees and tricks them to get more information. Scanning This is the second phase of hacking framework and involves acquiring more detailed information based on the data collected in early phase. This is very similar to the active reconnaissance and in this phase it tries to dig into little deep. Generally this phase includes activities such as indentifying live hosts, discovering running services and their ports, detecting the running OS. Main target in this phase is to build the blue print of the target network including the live host IP addresses, opened service ports. The hackers use various scanners in this case and few of their techniques listed below. Ping To identify the active hosts in a networks Ping is the best tool. It can provide the information such as status of the host, host name and their TTL details. It is a very simple utility uses ICMP packets to scanning. Ping send ICMP packets to a target host and if it receives the acknowledgment we can make out the system is active. There are few handy tools that can be used to automate this ping process to check the availability of range of IP address. Few examples of them are Hping, icmpenum, NetScan Tools. Traceroute Traceroute is a tool that can use to mapping the location of a targeted host. It uses same technology as Ping and shows the exact path to the target host. NMap NMap is the most popular port scanning tool and it is a free and open source utility. Both malicious and genuine users use to identify vulnerabilities on computer systems. It has many options and it is able to perform almost every type of scan like connect scan, half open scans, SYN scan etc on a targeted host. Also it is a very useful tool for task such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. NMap can scan host in a network range straight away and it is able to detect the versions of the operating system that running on the targeted system too. WAR Dialling This is a tool widely used earlier time to detect active modems in the networks. This was a common hacking tool as there were many deal-in modems available in the network to enable their employees to login into the network. The program can automatically dials a defined range of phone numbers and logs the success full attempts in to its database. But as the modem technology is getting obsolete very fast this is not using very much. Banner grabbing Another useful technique to find about running service ports is called banner grabbing. In this case the hackers tries to connect to well know port such as 80, 8080, 25, 110, 23, 22 etc using telnet. So if the trying service is running on the target server it will display the service banner including the type of the software and running version. Thus the hackers can grab that information to their building blue-print. Enumeration (OS / Application Attacks) This is the hacking technique of convincing some target servers to provide them some information about the system which are vital to precede the attack. The information the attackers normally target are resources and shares available in the system, valid users and user groups and about running applications etc. The common way of enumeration is by use of the null sessions, the sessions which usually have no username or password. Once the hacker gets into the system the he starts enumeration by using some tools to find out the data he wants. There are several tools available that uses to do these queries. NBTscan and Netbios Auditing tools are few commonly using tools. Hackers also enumerate the systems using the SNMP protocol too. Enumerating the SNMP protocol hackers can get the information they want easily. This is an easy way than using null session. But as SNMP v3 sends data after encrypting it, that data need to be decrypt before use it. SNMPutils, IP Network Browser, SNMP Informant, Getif are some of tool use for SNMP enumeration. Gaining Access As all above phases are only hacking preparation phases, this is the phase the actual attack is executing. The hacker will use the blue-print he created during previous phases. During this phase the attacker tries to launch attacks targeting the applications, operating system and the network. To do that, hackers may launches DoS attack, buffer flow attacks, application attacks and even they may insert viruses and Trojan horses to get access to the network. Another goal of the hackers is to gain the highest level privileges he can get. If so, he will able to delete all the tracks and evidence of his activities without any issue. Also if the NetBIOS TCP 139 port is open and accessible the easistt way to login to the system is guessing the password. Thus the first attempt of the attacker will be guessing the system passwords to enter with the highest level of privileges to the system. Most of the times, this step will be an easy task, because most of the users keep their password to an easy-to-remember one. Also if any information available about the user like family members names, childrens name, birthday, there is a great potential to be the password one of them. Also there are lists of commonly using password and the hackers can try those passwords to login to the system. If they were unable to guess the password, the next step is to crack the password using an automated tool. There are several strategies used by the hackers to crack passwords. Social Engineering The easiest and the common method to crack password and the hacker calls or meet the user get the password from him tricking by some fraud. Dictionary cracking In here the cracking is performing using some collected words related to the user and list of commonly using password. The list is checking one by one and usually this is an automated process doing by a tool such as Legion. Brute force cracking This is an automated password cracking mechanism and this will just use combination different characters, letter and symbols to guess the password instead of dictionary words. Hybrid cracking This is a mixed mechanism of both dictionary and hybrid password guessing mechanisms. It will first try the dictionary passwords and then tries the letter combinations. Some automated password-guessing tools are Legion and NetBIOS Auditing Tool. However, the tools like L0phtCrack,ScoopLM, KerbCrack will allows the system administrators to audit there users password and let them know if anyone using such password which can be compromised to a password cracking tool. Other than above mentioned password cracking methods, hackers use keystroke loggers to intercept the uses key strokes to find their passwords. Those keystroke loggers are able to save into files or send all the user key stokes to a remote destination. There are two types of keystroke loggers. It can be either software based or hardware based. The hardware keystroke loggers must physically be installed into the system and the software keystroke loggers can be a action of a Trojan-horse. Few examples for keystroke loggers are ISpyNow , PC Activity Monitor , Remote Spy and following figure shows an example of a hardware keystroke logger. If the hackers could not able to track down the user password the hacker will try to get access to the systems using network attacks. There are several methods hackers will use to attack the networks. Following listed are few of them. Sniffing Attacks Sniffing id the process of capturing data from a network as they pass and storeing them to process offline. To this process hackers use various sniffing tools with different capabilities. Some sniffers can only work with TCP/IP while more sophisticated sniffers works with many other protocols including data link layer protocols. Also sniffing attacks can be use to grab user logins and passwords too. As the telnet, http, POP, SMB sends password data in plain text and travel around the network using sniffing attack they can be easily grabbed out. Sniffing can be either active or passive. Passive sniffing is performing at Hub networks and the speciality in there is that the all the machines in the networks sees all the traffic of the other machines. So the hackers can capture almost every data packet travels through the network. As the hub networks are not in real environments passive sniffing is very unlikely to happen. Active sniffing is takes place in switch networks and thus the hackers will not able to see other users traffics except the broadcast data. Thus the only possible attack is the man-in-the-middle attacks. In here an attacker is positioned in the middle of communications between two legitimate entities in order to capture data that passes between the two parties. As mentioned earlier, there are several sniffing tools available with different capabilities. The most popular sniffing tool is the Wireshark and it was formally known as Ethereal. It is a free network protocol analyzer and supports for both Windows and Linux operating systems. It is a very sophisticated tool and it is capable of capture traffic on the network and save it on disk, filter traffic according to the requirement and showing summery and detailed information for each packet. Few of other sniffing tools are Packetyzer, Dsniff, TCPDump, and Snort. Dos Attacks A DoS attack is a network attack that results in some sort of interruption of service to users, devices, or applications. Hackers use several mechanisms to generate a DoS attack. The simplest method is to generate large amounts data appearing as a valid network traffic. This type of network DoS attack saturates the network so that valid user traffic cannot get through. A DoS attack takes advantage of the fact that target systems such as servers must maintain state information. Applications may rely on expected buffer sizes and specific content of network packets. A DoS attack can exploit this by sending packet sizes or data values that are not expected by the receiving application. These attacks attempt to compromise the availability of a network, host, or application. They are considered a major risk because they can easily interrupt a business process and cause significant loss. These attacks are relatively simple to conduct, even by unskilled hackers. Maintaining Access By entering to this step the hacker has to be getting in to the system by any mean and this phase it is focus on to the established session maintaining. Thus the hacker is able to perform any file upload/download or any software tool inserting. In this stage hackers are trying to establish a hidden path to enter to the system next time easily. So to do that, they will insert some malicious software like Trojan-horses, sniffers keystroke loggers etc. Trojan-horses are malwares that carries out malicious operations under the appearance of a desired function. A virus or worm could carry a Trojan-horse. A Trojan-horse contains hidden, malicious code that exploits the privileges of the user that runs it. Games can often have a Trojan-horse attached to them. When running the game, the game works, but in the background, the Trojan-horse has been installed on the users system and continues running after the game has been closed. The Trojan-horse concept is flexible. It can cause immediate damage, provide a back door to a system, or perform actions, such as password capturing, keystroke capturing, executing DoS attacks. Some advance hackers writes custom Trojan-horses according to the requirement and those are very hard to detect. There are many examples of Trojan-horses like Tini, netcat, subseven, backoffice etc. Clearing Tracks This is the final step of the hacking framework and in here the hackers delete all the evidence and track of their access. Generally, in any operating system it keeps a record about the user logins, file deletes, file inserting, installing etc. So once hacker loges into a system his attempts and actions are logged in to operating system log files. So the hackers have to delete these logs. Although this is a very hard task to perform in reality, there are some tools do alternative actions such as disabling the operating system auditing, deleting all the log records, delete temporary log files etc. So executing tools like that they can delete their tracks, usually with all the other log files. There for system administrator may know that system has been compromised. The software tool auditpol.exe is a such tool that able to disable OS logging. Also attackers need to hide the files they uploaded in to the systems and to do this there are few techniques available call wrappers. These wrapper tools are able to hide the uploaded data as picture file. Design an Evidence Gathering Prototype Importance of a Evidence Gathering Prototype As shown above, the possibilities and opportunities are limitless a company can be targeted by a malicious attack. Although implementing correct firewall and security policies can minimize the exposure of many systems to the hackers, it is very unrealistic to completely avoid security breaches in a comport system. Therefore, it is very important to detect intrusion activities and limit as much as possible the damage they can produce. Installing well planed and configured Evidence Gathering Prototype with intrusion detection and honeypot capabilities will do that. In generally, intruder detection systems are able to record all the system activities on a given host or a network. Thus if the monitoring system is compromised or targeted to attack, all the useful information to track the attacker, are recording in the IDS system. Sometimes they can alert the system administrators about the attacks as well. One of another feature of such kind of system is that they are able recognize violations of an organisations security and acceptable use policies such as transfers of inappropriate material throughout the companys network, or downloads of authorizes data files, accessing restricted contents, use of unauthorized application, etc. Also, some systems are able to identify reconnaissance activities which may followed by hacking attacks. As these systems are able to keep log on every said incidence, the systems administrators can use those data in there ethical hacking exercises. Furthermore, they can get idea about the techniques attackers use, attack launching periods, times and frequencies, common types of attacks they get and about the locations of the attackers and etc. One of the side advantage can have installing a IDS system is that the deterring of hacking attempts, because being aware that their activities are being monitored the hacker might be less prone launch attacks. Thus installing a system in purpose of evidence gathering is very crucial and rest of this document will focus on designing a better prototype for that purpose. For example, a hacker can identify whether an IDS is present in the system if present that attacker may first attack the IDS to bring it offline. Architecture of the prototype The general idea of this prototype is to provide new defence mechanism to networks from huge varieties of behavioural network attacks. Especially rootkit attacks, buffer overflows, DOS / DDOS attacks, SQL injections and many other types of hacking in to a network. Keeping records of malicious behaviours and providing tracking down the intruders, this system will be a whole new protection concept for current networking intrusion threats. Techniques like Intrusion Prevention Systems, Honeypot and network Sniffers can be used as first line of defence to fights again unauthorized access to networks and network resources. But it is hard to use each of them separately in a network to prevent malicious attacks. So a good system should use all those techniques in a single system. Also only one technique will not suit either, as they may have some tribulations on it. Thus, the designing prototype uses all the techniques mentioned above. It will work as a choke point between the WAN and LAN so all the network traffic should flow through it and the traffic will inspect from there. About architecture, the prototype is consisting of three Intrusion Detection Systems, Honeypot and a monitoring console. Three IDSs will be Signature based, Anomaly based and Stateful-protocol analysis IDSs. All the incoming network traffic will be inspected by these IDSs before enter in to the LAN. If IDSs are detected any suspicious behaviours, they will send an alarm message to the Honeypot. Then the malicious traffic will start to circulate among the IDSs without the intruders knowledge. Therefore an intruder will not be able to perform continuous actions because the IP addresses of the traffic are keeping changing. The Honeypot monitor all the network traffic which will be forwarded by the IDSs and keep records of all behaviours. Allowing or denying the network traff ic to enter in to the LAN will be decided by monitoring the behaviour of the incoming traffic to the Honeypot. A separate monitoring console is connected to the Honeypot which also has an online monitoring and log making system so that the sources of any malicious traffic can be identified. Following figure show the overview of the system. Major components Signature based IDSs has a predefined database of attack signatures. It compares all the network packets against the attack signatures in the database. Anomaly based IDSs compares the network traffic against a profile build by previous trainings of network traffic behaviours and continually sampling all activities occurring within the system. Therefore it can react to new zero-day attacks. Stateful-protocol analysis IDs relies on vendor-developed universal profiles that specify how particular protocols should and should not be used, on decision taking. Core of the system is the Honeypot which will monitor all the network traffic flow through it. Monitoring console with a real time log making and tracking system implemented on it. This console provides a real time monitoring and online tracking system to track down and locate the intruders source. Network traffic database will store all the information about the traffic flow the Honeypot encountered, signature database and IP addresses of all the malicious / suspicious traffic flows. Capabilities of the prototype Signature based Intrusion Detection System Knowledge is accumulated by the IDS vendors about specific attacks and how they are carried out. Models of how the attacks are carried out are developed and called signatures. Each identified attack has a signature, which is used to detect an attack in progress or determine if one has occurred within the network. Any action that is not recognized as an attack is considered acceptable. Anomaly based Intrusion Detection System These are behavior based products that do not contain databases of attack signatures. They first go through a learning mode to build a profile of normal behaviour of a system or a network by continually sampling all activities occurring within the system. These IDSs will be configured to detect the Zero-day attacks which means configured to detect new and unknown threats. All anomaly based IDSs will be trained by using accepted penetration tools such as GFILanguard, Nesses, Nmap, Retina, NetCat and Enstealth. After the profile built all the activities are compared against it. If anything which does not match the profile occurs an alarm is triggered and packets will be tagged. Stateful-protocol analysis Intrusion Detection System This is little similar to anomaly-based detection technique. But it relies on profiles that provided by the device vendors. Those profiles enable IDPS to understand and track the state of network, transport and application protocols that have a notion of state. It can thus identify unexpected sequences of commands, such as issuing the same command repeatedly or issuing a command without first issuing another command upon which it is dependent. Honeypot Honeypot is an essentially decoy network-accessible resource, could be deployed in a network as surveillance and early-warning tools. Techniques used by the attackers that attempt to compromise these decoy resources are studied during and after an attack to keep an eye on new exploitation techniques. Such analysis could be used to further tighten security of the actual network being protected by the Honeypot. All traffic entering and leaving the Honeypot is logged. Honeypot can carry risks to a network, and must be handled with care. If they are not properly walled off, an attacker can use them to break into a system. Monitoring Console This machine is to examine the intrusion methods / traffic flow used by the intruder. This analyze will be done synchronizing with the Honeypot. Those details will be used to create complete reports about the encounters. The tracking system which is installed on the console will provide a complete track of the intruder. Other Features The prototype can analyze the behaviours of the incoming traffic since all the traffic should go through the system. Any intrusions which will match to the signatures, the Signature Based IDSs will alarm immediately to the Honeypot. By recording and tracking the traffic pattern, a decision can be taken whether to drop the identified traffic or track back the source of the intruder. The detected or suspicious traffic will be redirected to the Honeypot as the final action. Make use of the online tracking and log making system, the prototype can record all the behaviours in real time and provide a tracking system to catch the intruders. Commercially available Intrusion Detection Systems Snort Snort is a free and open-source network-based IDS system and it is the most commonly using intrusion detection system. It is a software-based NIDPS and able to perform both protocol analysing and content searching. Snort has intrusion prevent capabilities as well. So it is use to both actively block and passively detect a variety of attacks and probes. It uses signature, protocol and anomaly-based inspection to intruder detection. CISCO Secure IDS This

Meet Me in St. Louis & Raging Bull :: essays research papers

The 1940’s were a time when most were living with the effects of war every day. Whether it be stomaching the violence of war or trying to deal with the absence of male family members in the family unit, everyone was shaken by World War II. Therefore it is easy to see how a movie such as Meet Me in St. Louis was born. It takes us back to a time that is associated with wholesome family values and a world with less major problems before war had directly affected Americans of modern times. A film of a different nature, Raging Bull, takes place in these violent times displaying to us not what the people of the 1940’s longed for, rather showing some of what society lived with back then. These two movies seem as different as night and day when viewed together, yet they simply show different sides of the spectrum of the same themes. The source that led to the desire to produce such movies is one and the same, violence.   Ã‚  Ã‚  Ã‚  Ã‚  Although I am yet to know serious effects of war, I know what it is like to want to escape from something and to find that escape in watching a movie. For many people in the 1940’s watching Meet Me in St. Louis was they’re escape from violence in society at that time. It makes perfect sense that a movie in which the biggest conflict is whether or not a family leaves their home together would be a success in a time when family unity was not as easy to come by. Vincente Minnelli directed it and provided the audience with singing and dancing, themes of love and romance, and overall a great deal of good values. His film represents the importance of family and relationship and he is able to show us this very well on screen.   Ã‚  Ã‚  Ã‚  Ã‚  Mise-en-scene was one method Minnelli used in displaying this sense of family unity and value. It is apparent in scenes of family interaction, whether it is conversation in the kitchen, celebrating holidays together, or sharing a family dinner together at the table. Behavior in this movie revolves around being loving considerate family members no matter what the action. Any smiles or excitement not motivated by direction were utilized and helped keep with the movies themes. When Mr. Smith brings about the conflict of the family having to move despite their wish to stay, almost immediately the family members disperse and leave him to himself.

Aristotle Vs. Copernicus :: essays research papers

Aristotle vs. Copernicus Aristotle was a Greek philosopher and scientist, who shared with Plato the distinction of being the most famous of ancient philosophers. Aristotle was born at Stagira, in Macedonia, the son of a physician to the royal court. At the age of 17, he went to Athens to study at Plato's Academy. He remained there for about 20 years, as a student and then as a teacher. When Plato died in 347 bc , Aristotle moved to Assos, a city in Asia Minor, where a friend of his, Hermias (d. 345 bc ), was ruler. There he counseled Hermias and married his niece and adopted daughter, Pythias. After Hermias was captured and executed by the Persians, Aristotle went to Pella, the Macedonian capital, where he became the tutor of the king's young son Alexander, later known as Alexander the Great. In 335, when Alexander became king, Aristotle returned to Athens and established his own school, the Lyceum. Because much of the discussion in his school took place while teachers and students were walking about the Lyceum grounds, Aristotle's school came to be known as the Peripatetic ("walking" or "strolling") school. Upon the death of Alexander in 323 bc , strong anti- Macedonian feeling developed in Athens, and Aristotle retired to a family estate in Euboea. He died there the following year. His works on natural science include Physics, which gives a vast amount of information on astronomy, meteorology, plants, and animals. His writings on the nature, scope, and properties of being, which Aristotle called First Philosophy ( Prote philosophia ), were given the title Metaphysics in the first published edition of his works (c. 60 bc ), because in that edition they followed Physics. His treatment of the Prime Mover, or first cause, as pure intellect, perfect in unity, immutable, and, as he said, "the thought of thought," is given in the Metaphysics. To his son Nicomachus he dedicated his work on ethics, called the Nicomachean Ethics. Other essential works include his Rhetoric, his Poetics (which survives in incomplete form), and his Politics (also incomplete). Some of the principal aspects of Aristotle's thought can be seen in the following summary of his doctrines, or theories. Physics, or natural philosophy. In astronomy, Aristotle proposed a finite, spherical universe, with the earth at its center. The central region is made up of four elements: earth, air, fire, and water. In Aristotle's physics, each of these four elements has a proper place, determined by its relative heaviness, its "specific gravity." Each moves naturally in a straight line-earth down, fire up-toward its proper place, where

Charlie Don’t Surf: The Clash Protest Imperialism Essay -- Political P

By definition, imperialism is extending a country’s power and influence through diplomacy or military force. That ideology is best exemplified by the Vietnam War because the United States invaded North Vietnam to prevent the dissemination of Communism into South Vietnam, which is ultimately an attempt at exuding power and influence by using military force. The Clash recognized the homogeneity between the American imperialism of the Vietnam war and the forced Westernization of the non-Western world, particularly third world nations; thusly, the band chose the Vietnam War as a backdrop for â€Å"Charlie Don’t Surf† because of it’s relevance to American culture at the time. The Clash released the album Sandinista! in 1980; this album is home to the highly overlooked song â€Å"Charlie Don’t Surf.† The intent of this paper is to analyze the song â€Å"Charlie Don’t Surf† and examine it’s use of historical and cultural compone nts to protest imperialism forced upon third world countries by the United States. This paper will specifically analyze The Clash’s emergence from a tumultuous political climate as well as the decision to title the album Sandinista!. Musical composition and lyrical structure aids in demonstrating the protest of imperialism upon multiple levels and distinguishes the link between the â€Å"Charlie Don’t Surf† and a similar scene in the film Apocalypse Now. Emerging from England’s punk rock scene in 1977, The Clash morphed from traditional punk beginnings into the new wave movement. Described as â€Å"a more genuine, radical, proletarian,† sector of the punk genre, it was evident the band was destined to transcend musical boundaries.1 The Clash’s trademark idiosyncrasy is their layering of cultural remarks with historical relevancy througho... ...rus of â€Å"Charlie Don’t Surf† in the car, or helicopter, does not provide the background knowledge of the songs origins. In a way, without paying attention to the song, it mocks the ability to lose people into the music. Works Cited 1 Moore, Allan F. "Punk Rock."

Harvard case essay

Treasury bonds with the same maturity. The deference between selling TIPS and buying T-bonds will cover the Inflation risk losses thus effectively eliminates Inflation risk In the portfolio. The Harvard's Policy Portfolio Includes much of the university endowment, pension assets, working capital, and portfolio contains 1 1 wide asset classes, Including domestic equity, foreign equity, private equity, domestic bonds, foreign bonds, emerging markets, real estate, commodities, absolute return, high yield, and cash.This portfolio was determined by the board of the corporation for the long-run allocation, however, the manager can make short-run adjustment within the limits from the guideline. The reason that HAMS focus on real returns is HAMS want to exclude the influence of inflation and determine the return rate more precisely. As the formula nominal return = real return + inflation rate shows, choosing real return instead of nominal return can reveal the real purchasing power of the in vestment, thus help the manager to conduct more efficiently to prevent the evasion of the investment.As we can see from Exhibit land Exhibit 2, domestic and foreign equity constitute the biggest part of the portfolio, and these two asset classes have high real returns as well as latterly larger standard deviations. And we know that equity premium indicates the difference between the expected return on the market portfolio of common stocks and the risk-free interest rate, and higher risk often indicates higher equity premium.Based on Ham's assumption that the real growth rate of annual spending is 3% after inflation, and that gifts to the endowment are same as the historical average rate (1%), HIM has to maintain a real between 6% and 7% of the total investment In order achieve its preservation goal. Thus HIM has to invest a large portion in US and reign equity with higher premium, resulting in a short of cash. Yes, From inception in 1 997, TIPS had offered a real yield that ranged f rom. 2% to 4. 25%.

Analysis of a Mapping Programme: Neogeography

IntroductionNeogeography, liter t turn up ensembley intending sweet geography is basically a do-it-yourself function scheduling, which is going progressively fashion adequate and powerful today ( Wikipedia.org ) . In the past, do roles online was left to the GIS specializers who knew the art and linguistic communion of GIS ( C. Morais, 2007 ) . Neogeography, on the some other(prenominal) manus digest be used by devout whatever cardinal with no expertness or dos ask in function, because of this some respect neogeography to be a subset of GIS, patch others consider neogeography to go k delirioused GIS ( A. Turner, 2006 ) . Neogeography is fun as one bunghole make things such(prenominal) as band the localization principle of their first buss, or vacation, neer once more will one battle to retrieve where a pictorial matter was taken ( A. Turner, 2006 ) . In a nutshell, neogeography is all about peck utilizing and making their personal maps, sharing information and lieus with house consecrate and friends both(prenominal) bit upright as geotagging images of vacations, while obt personaling utile penetration of that location.NeogeographyGeocoding is of import in neogeography as they provide co-ordinates of a location, which support so be processed ( A. Turner, 2006 ) . For illustration, when users government agency a image to applications such as Facebook or Instagram, it besides lets them label the location where the image was taken and at that placefore, cognition is g ained in this elan. Some illustrations of neogeography is Google Maps, Google creation, Yelp, SaveMe999, integrityMap, OpenStreetMap, UCrime among others ( A. Coote and L. Rackham, 2008 ) . While each of these puddle their utility, neogeography besides comes with the power to destruct.Neogeography-hit or withdraw?The reinforcements of neogeography is legion and each neogeography application has its ain specific power that makes a users life easier. For illustrati on, the SaveMe999 application designed in Malaysia, specifically to turn to the disabled community curiously the deaf and deaf person ( R. Anas, 2013 ) . Undoubtedly, this is a spacious advantage to the handicapped citizens, as SaveMe999 uses GPS information in the users smartphone to place the callers location when they call and therefore answer suffer be sent to the right adduce as location is one of the virtually of import facets in directing an indispensability response ( R. Anas, 2013 ) . Disabled wad eject hence be more independent, every bit good as expression more safe and secure.Google Maps and Google footing is other great illustration of neogeography. Google Maps is utile such that it shows waies from one location to another, either by auto, motorcycle or walking by demoing the relevant street maps. It besides shows the expect clip that it will take the user to make their finish and one of the some utile characteristic of the Google map is that it tail ass embly be viewed in three antithetical manners terrain, a normal map position and orbiter position ( M. Cornock, 2011 ) . star rump besides custom-make their ain maps in Google maps which piece of ass be saved, implike or printed out at any clip ( L. Storm, 2007 ) . Google Maps, nevertheless, promotes communicating isolation, as onward Google Maps verbal waies was an of import accomplishment to give birth and understand but with the enlargement and move popularity of Google Maps verbal waies are deceasing out ( L.Storm, 2007 ) .Google Earth meanwhile, shows orbiter and aerial imagination of the contract location in 3D. This is used for umteen convinced(p) effects. For illustration, the World Wide inventory uses it to protect the Sumatran Liberation Tigers of Tamil Eelams, alleviation workers uses it for crisis response after indwelling catastrophe, and it is besides used for environmental show ups such as pollution.Possibly, the finest illustration of how Google Maps an d Google Earth came to assist an environmental issue is the instance of the Appalachian Mountaintop remotion, in which excavation companies removed the excel of mountains in order to mine for coal. By utilizing Google Earth and Google Maps conservationists were able to analyze the devour table of a really dramatic environmental job and was besides able to pass on this issue to the people in the community who so took fulfill to protect their mountains ( Google Earth Outreach, 2010 ) . In the 10 yearss following the release of the Appalachian Mountaintop removal bed in Google Earth, more than 13,000 people signed an on-line request to plosive consonant mountaintop removal ( Google Earth Outreach, 2010 ) . Therefore, it kitty be seen how Google Map and Google Earth is used for positive impacts.However, Google Earth and Google maps cigaret be misused. One of the most concerning factors is privacy and security, the fact that anyone can happen anything is rather diswhitethorning particularly for safety grounds. Other disadvantage of Google Earth and Google Map include inaccuracy of information, unavailability as users need right Personal information processing system demands and cyberspace, less developed states are ill represented every bit good ( S. Myer, 2010 ) . Furthermore, satellite imagination can take in images that are non delighting to the oculus such as force or war.UCrime.com is a drop out online service that provides easy to read criminal offence maps and have automatic qui vives for people that heed universities or montages ( A. Coote and L. Rackman, 2008 ) .Users so receive agile electronic mails if a offense has occurred near a selected college or university and in this manner there is public safety, besides users can supply tips and thoughts to assist work out offense in the country in which they operate in ( A. Coote and L. Rackman, 2008 ) .Some customary advantages neogeography has to a user are it helps users fall topographic p oints based on other peoples stations, it besides increases consciousness of geographics since anyone can larn how to utilize and make their ain maps, moreover, neogeography allows everyone to lend to the development of the digital mankind and immense sums of informations and information is made visible(prenominal) by users ( A. Schuyler, 2009 ) . Using neogeography saves clip and specie for concerns and organisations and eventually, possibly the greatest advantage of neogeography is that anyone can make maps, they do non necessitate to hold makings or be a pro in function.On the other manus, there are besides several disadvantages in neogeography and one of the biggest menace of neogeography is its informations tincture its truth, completeness, consistence, and whole step confidence ( A. Coote and L. Rackham, 2008 ) . Since users prepare the maps the information king be wrong and undependable, this can repelling effects, for illustration when be aftering a holiday. Besides , when making the maps the Godheads can either add as well much unneeded information or possibly excessively small, lending to the deficiency of completeness of the information ( A. Coote and L. Rackham, 2008 ) . Neogeographic datasets makes small mention to quality confidence, some maps created utilizing neogeography have no 1 to supervise the quality and dependability of the maps ( A. Coote and L. Rackham, 2008 ) . earnest and cliquishness as discussed before is another disadvantage, as sometimes it so happens that when users create the maps, they may roll up informations from private locations which the proprietors mogul dislike. Finally, the enlargement of the digital reality could intend less geographic pilgrimage in the existent universe, people might worsen in sing things maiden manus as they can question topographic points online in neogeography and therefore, people may bit by bit go stray from the existent universe.DecisionIn decision, neogeography, if non exploite d helps us a great trade and the hereafter of neogeography is in our custodies and we have a opportunity to utilize it or misapply that power.Reference ListAndrew Coote and Les Rackham.
