Week 2 - Essay Example This performance management plan in healthcare is efficient in gauging the organization for success. This paper will explain the maintenance and development of a culture for outcomes oriented care within a healthcare organization. An organization-wide performance management plan focuses on the performance of an organization, a department or even the employees in the organization. This also applies in healthcare organizations in order to improve healthcare quality. In the past, the clinical decision support system was derived from an expert research. According to various sources, these systems have a significant impact on patients. The system developers were striving to create a program which was able to act just like a human clinician (U.S Department of Health & Human Services, 2009). Nowadays, these systems relate to a wide range of options. Furthermore, there are several types of the support systems in healthcare. Research asserts that these systems are effective in improving the quality of health services provided in a healthcare organization. For example, these systems have significantly lowered the rate of medication errors. This has immensely lowered the adverse drug effects on numerous patients. These systems also provide supportive diagnostic suggestions for some infections. Furthermore, the system is also able to predict some of the potentially hazardous drug interactions. The clinical decision support systems also have an impact on the structure of the organization. Research asserts that these systems have substantially lowered health care cost which is caused by the side effects presented by drugs (U.S Department of Health & Human Services, 2009). On the other hand, cultural competence in health care can be achieved by the hospital staff when they examine their own beliefs and values (Galloway, 2005). The nurses are usually advised to implement and evaluate culturally sensitive care in order to challenge prejudice and

Honorary members of the institution Essay Example for Free

Honorary members of the institution Essay It is with great pride and honor that I express my heartfelt appreciation for giving us, the students, and the guidance that we need to pursue with taking our dreams and for having been given the chance to enroll in an institution with competent instructors and high quality learning. The competence of the school is beyond compare greater than what I have first expected upon stepping on the floors of this prestigious foundation of education. Hence, with all due respect, I believe that what we have acquired in this institution, all the rationally beneficial fundamentals need to be harnessed on a larger view of human behavior. It is evident that there are skilled and outstanding students who are good at writing—academically able—hence possess dilemmas when it comes to public speaking, socially crippled and unable to open up their â€Å"social abilities† which I believe plays an important role as a university student. We, the students, are expected to raise the name of the institution with flying colors. In behalf of the future professionals intellectually crafted by this institution marvel, we are requesting for a summer camp which will cater several seminars on public speaking with the help of public relations and parliamentary procedure specialists so that we shall be thoroughly prepared when we finally face the bigger world that awaits our journey in life. The seminar will not only draw out the intellectual capacity of the students, but it will also enhance the students’ social skills and moral values by interacting with the other graduates. The series of seminars will also be charity work, wherein the proceeds shall be offered to deserving outreach organizations so as to start shaping the youth not only as students alone, but as public servants as well. We are asking for the administration’s benevolent support in pushing through with this activity since we believe that it is our teachers who can lead us to the brightest star there is.

SQL Injection and Buffer Overflow Attack Detection

SQL Injection and Buffer Overflow Attack Detection CHAPTER ONE INTRODUCTION This chapter discussed about research requirement for this research. It discussed briefly the research background in section 1.1, problem statement in 1.2, research objectives in 1.3, research questions in 1.4, scope of research in 1.5, research elements in 1.6 and research significant in 1.7 1.1 Research Background The internet which is a free, supportive and self-sustaining facility reachable to hundreds of millions of people worldwide, have become one of important communication’s medium today. The greatest widely used part of the Internet is the web or World Wide Web (WWW). The Web uses the Hypertext Transfer Protocol (HTTP) to convey data through the Internet as HTTP is a well-known language over the Internet. There is a Web Browser that acts as the main door to the Internet if user wants to view the web pages in different websites. Web pages is a document that may contain text, videos, sound, images or any multimedia components created in Hypertext Markup Language (HTML). In addition, to make the process of searching specific web pages easier, there is Uniform Resource Locator (URL) where it standardized naming convention for addressing documents available over the Internet or Intranet. As Internet become more and more significant, there are some individuals identified as hackers that have the ability to interrupt the peace of using Internet. For that reason, network security is required. Network security emphasis on securing networks from any violence or exploit especially from hackers and typically handles by network administrator on each organization that applies security policy. Thus, to ensure the three main goals of security which are integrity, availability and confidentiality is guarantee, network security become the main role to some kind of vulnerabilities in web application. Vulnerabilities can be referring as the flaws where attacker can take benefit by exploiting it to gain unauthorized access to their target. There are two of the most common web application vulnerabilities that exist in a web application are Structured Query Language (SQL) Injection and Buffer Overflow (BOF). SQL Injection is an attack in which the attacker inserts SQL commands into form or parameter values. It exploits the use of SQL query in the application. SQL Injection has become a predominant type of attacks that target web applications. The Open Web Application Security Project (OWASP) ranks it on top among the Top-10 security threats. Buffer Overflow is an exploit that can make the memory allocated to a certain application become massive. For example, an application expecting a five-digit postcode therefore the programmer only allocates enough memory for the perimeter. If an attacker enters more than five digits for example hundreds of digit, the application will end up using more memory than what it should. As of September 2010, 12 of the 20 most severe vulnerabilities ranked by US-CERT were Buffer Overflow related. There are a lot of web application vulnerabilities detection scanners existing in Internet. Either it free source or need to buy, there are more or less problems faced by these tools. The common problem meet by some of the scanner are false positive and false negatives. A false positive is when there is an error whereby a web application tested for is mistakenly found the vulnerabilities which actually there is none. Meanwhile, false negatives are the scanner does not found any vulnerability in a web application and telling user that the web is secure. However, actually the web application may have some vulnerability. Thus, by proposed a method for detecting the web vulnerabilities through searching for the suspicious and defined web vulnerabilities criteria, it will help the web application administrator to take a look and always standby in secure mode to avoid and secure mode for avoiding any attacks from the attacker. 1.2 Problem Statement Usually developers of a web application does not realize that their web application have vulnerabilities. They only realize it when there is an attack or manipulation of their code by someone. This is normal as in a web application, there are thousands of lines of code so, it is not easy to detect if there is some mistakes (Houghton, 2013). Nowadays lots of new hacker are born as the tools and tutorials are easier to get. According to Dougherty (2012), even though SQL Injection is very easy to protect against, there are still large numbers of the system on the internet are vulnerable to this type of attack because there will be a few subtle condition that can go undetected. Besides, in Buffer Overflow, although many methods have been proposed to address this problem, it mostly very high overhead involves considerable additional resources (Zheng, Zhou Liu, 2015). Therefore, a detection method for detecting the SQL Injection and Buffer Overflow while producing minimum false positive a nd false negative was proposed. 1.3 Research Objective There are two objectives that have been achieved in this dissertation: To construct a detection method that can detect SQL Injection and Buffer Overflow attack in web application based on acknowledged features and characteristics of the vulnerabilities. To evaluate the performance of proposed method in term of accuracy and efficiency by conducted two sets of experiments under laboratory testing environment. 1.4 Research Questions There are four research questions that have been addressed in this dissertation: Is it possible to employ a dynamic method for SQL Injection and Buffer Overflow detection in web application? What are the criteria used to detect SQL Injection and Buffer Overflow in the proposed detection method? What is the evaluation metrics used to measure the performance of the proposed detection method? How to measure the accuracy and efficiency of the proposed detection method? 1.5 Scope of Research This dissertation focused on the web application vulnerabilities which are more specific on SQL Injection and Buffer Overflow. This dissertation limited to: Detection of web application vulnerabilities which are limited on: SQL Injection Buffer Overflow A number of vulnerable website’s URL collected from: http://www.thetechnism.com/ http://pastebin.com/ For detection of web application vulnerabilities of SQL Injection and Buffer Overflow, the criteria used are: Get the URL of website Tokenize the URL Match the pattern with the matching criteria based on Boyer-Moore Algorithm Get the web application vulnerabilities The evaluation metrics that used in this dissertation are accuracy and efficiency 1.6Research SIGNIFICANCE There are two significances of this dissertation: This dissertation able to provide a method that can detect SQL Injection and Buffer Overflow attack based on Boyer-Moore String Matching Algorithm. This proposed detection method also able to generate the report regarding the level of vulnerability of the web application. The proposed method can assistance the web application developer or administrator to take any extra action to protected their application from being attacked by the unethical person outside the network to SQL Injection and Buffer Overflow attack.

Jane Campions, The Piano :: essays research papers

In the spring of 1993, a film was released to the world that would end up changing the way many people perceived and appreciated films, especially those made internationally. It would be delivered from New Zealand’s most famous female filmmaker. Jane Campion, the director whom was previously known for her films, Peel-an Exercise in Discipline, and Sweetie, would achieve even higher acclaim for her masterpiece to date, The Piano.   Ã‚  Ã‚  Ã‚  Ã‚  The Piano portrays the story of a mute, unwed Irish woman in late 1800s New Zealand, arranged into a marriage with a colonial New Zealand settler. The main character, Ada, expresses herself with the keys of her piano. She finds herself falling in love with Baines, one of the natives of her new home, after he persuades her to give him piano lessons in exchange for her beloved musical instrument. Ada is very emotionally distant with her new husband, and as he discovers the romance between her and his intense neighbor, he becomes competitively jealous. In a pit of rage, Ada’s husband severs one of her precious fingers and eventually gives up on the failed marriage. In the end of the film, Ada and her young daughter, Flora, set off from the island with Baines to start a new life, without her once loved piano.   Ã‚  Ã‚  Ã‚  Ã‚  The characters in this film hardly come shy of delivering performances that make for amazing cinema. The actors in The Piano include Holly Hunter, Harvey Keitel, Anna Paquin, and Sam Neill. Holly Hunter’s character, Ada, delivered a fantastic performance on camera. Although many average moviegoers and few critics may discard Hunter’s role as achievement since she didn’t have to memorize any lines, the majority of film critics worldwide certainly disagreed, as Holly Hunter ended up taking home the Palme d’Or and an Academy Award for best actress soon after the films release. Hunter’s films previous to The Piano included films Raising Arizona, and a film by acclaimed Simpson’s producer, James L. Brooks, entitled Broadcast News (Davis 1.) Campion noted that as she was deciding whom to cast as her admirable Ada, that Hunter was not her imaginative image of the character at all: Holly was my image of Ada at all. But, in fact, I was very much saved from myself by Holly. Originally, I had an almost clichà ©d, romantic view of this tall, statuesque, black-haired, black-eyed beauty. In many ways, she wasn’t a very real human being, and when meeting Holly I was not very willing to see her as Ada.

Future of Our Galaxy Galactic Millenium :: Essays Papers

Future of Our Galaxy Galactic Millenium What Does the Future Hold? (adopted from an article by Greg Laughlin and Fred Adams, "Celebrating the Galactic Millennium", Astronomy November 2001) Not too long ago, we were looking forward to the New Millennium. To many of us, this was an important event of our lives. On a larger scale, however, the New Millennium looks insignificant. "If we adopt an astronomical perspective, however, a much larger and more distant celebration remains on the schedule-the Galactic Millennium," write Greg Laughlin and Fred Adam in their article Celebrating the Galactic Millennium. Laughlin and Adam speculate about the proposed changes to the Universe in the future and the coming of the Galactic Millennium. Present Day Galaxy According to the authors, the present day galaxy is relentlessly empty and spans a tremendous scope. In a scale model of the galaxy where stars are the size of sand grains, the nearest stellar system (Alpha and Proxima Centauris) is six miles away. Our Galaxy contains approximately 100 Billion stars. In this model, the stars move through their orbits at a pace of only a few feet per terrestrial year. The sun takes nearly 100 million terrestrial years to make a full circuit of the galaxy. The last time the sun passed through our current galactic longitude was in the middle of the Cretaceous period, when the giant continent Gondwanaland was beginning to break up into African and South America and the giant Carnotaurus enjoyed its place at the top of the food chain (before the reign of T.Rex). What Does the Future Hold? The authors' prospected views on the future of our galaxy are rather harsh. The authors argue that a billion terrestrial years from now-in 10 galactic years-the galaxy will look much like it does now. Certain details, however, will be different. As the sun executes its next ten circuits around our galaxy's central hub, our today-familiar constellations will be scrambled one hundred times over. Many of the night stars in the sky will no longer exist. Deneb and Rigel, for example, will explode as supernovae. Sirious will swell into a red giant and puff out a planetary nebula. Alpha Centauri, currently the sun's closest neighbor, will recede from the sun, and its apparent brightness will fade below the threshold of naked-eye visibility. As the next billion years unfold, Earth will face pressing problems because of sun's activity.

Free Essay - Nora in Act 1 in Ibsens A Dolls House :: Dolls House essays

The Character of Nora in Act 1 of A Doll's House The character of Nora, of Isben's A Doll's House, is particularly difficult to interpret. Her character is constructed by the combination of a number of varying traits.  Ã‚   Throughout Act 1 her ambiguity is particularly prominent. Her frivolous, playful moments are readily followed by moments of practicality and astuteness. It is not surprising that Nora is such a changeable character for she is constantly interchanging between three main roles: a supporting wife, fundamental mother and sexual being. Ibsen uses the metaphor of a doll inside a doll house to portray Nora's attempt to become an individual while confined inside a male dominated world. Her wish to become self motivated is obstructed by Torvald's power over her.   Nora's home is the realization of domestic bliss, preserved and presented like "A Doll's House." Lacking experience of life in the real world and oblivious to the outdoor hardships, Nora is vulnerable. She enters muffled in protection from the outside, portrayed symbolically through her coat, scarf etc. Immediately, Nora appears childlike and coquettish. She orders Helene in an excitable tone to hide the Christmas tree as the children "mustn't see it till tonight." Nora's secretiveness   in wanting to hide the tree, extends further, and is a constant theme. Following Torvald's light- hearted interrogation with regard to whether she has had any macaroons, she becomes nervous and lies, "No Torvald, I promise...No No...Torvald I swear." Of course, this is particularly important as the entire play rotates around Nora's "big secret."   With the entrance of Krogstad, Nora's sense of fun abandons her. Her attempt to enforce her social superiority over him is genuinely intimidated. In her ambitious attempt to be superior she states "one isn't without influence". However, within moments she is forced into pleading "Mr. Krogstad, I don't have any influence." Nora's stereotyped roll as a doll confined to a doll's house constantly being fathered by Torvald encourages her childlike manner. However an entirely different contradicting side to Nora's character is revealed when Nora explains exactly what she did "for Helmer".   Although Nora is a woman who shirks or is probably unaware of her responsibilities (particularly with regard to her children who are under permanent care of Ann- Marie) here she has, apparently, fulfilled something of her duty as a wife.   Her personal attitude to her action, which in her mind saved "Torvald's life" is very childlike.

Hutu Tribe

Hutu The mention of the word â€Å"Hutu† immediately conjures up images of mass murder from the 1994 genocide in Rwanda. The recent film Hotel Rwanda brought the horrible atrocities of that genocide to the public eye. However, it is not only in Rwanda that the Hutu have been involved in ethnic war. The country of Burundi, a neighbor to Rwanda, was the site of the first violence between the Hutu and the Tutsi. The Hutu people of Burundi have a rich culture and history that has been largely overshadowed by ethnic conflict. The Hutu are a Bantu tribe numbering about thirteen million (Newbury 2001).Traditionally the Hutu organized themselves in clans and family groups through patrilineal decent (Ndarishikanye 1998). Within these groups they practiced polygyny and bridewealth as part of the institution of marriage (McDonald et. al 1969). Like many African tribes the Hutu’s religious beliefs include the spirit world. The supreme God Imana is seen as the giver of all good whil e there are lesser spirits who do evil (book). The Hutu inhabit the high plateau of the central African Rift Valley and inhabited 85% of Rwanda and Burundi before the ethnic wars in those countries (CIA World Factbook).The Hutu inhabit diverse geographies. In the southeast region of the Rwanda and Burundi territory there are open grasslands which are ideal for pastoral people. In the western region of the countries there are mountains. The west is good land for agriculture because it reliably receives rainfall. In the northeast there are lowlands that are along Lake Tanganyika (Newbury, 2001). This vast array of ecologies provides different possibilities for food production or procurement.The Hutu are traditionally agriculturalist but they did get involved in herding cattle because of the closely related Tutsi tribe. The Hutu wanted cattle and the Tutsi wanted laborers. To appease both groups, agreements called ubuhake were made. These agreements exchanged the Tutsi cattle for the H utu labor. In other words when a Hutu entered this agreement he received cattle but in return became submissive to a Tutsi owner (Louis 1963). This is one reason that the minority Tutsi rose to control economics and rule over the majority Hutu, this would later lead to ethnic conflict.The ethnic conflict between the Tutsi and the Hutu is most famous in Rwanda but the Hutu of Burundi have also been severely affected by ethnic tension throughout the years. Understanding the causes and effects of the violence is a part of understanding the history of the Hutu people. The causes of the ethnic tensions between the Hutu and Tutsi are not simply explained. In fact, in 1931 Bernard Zuure, a missionary with seventeen years of work in Burundi, noted that it was pointless to distinguish between the Hutu and Tutsi because their cultures were so similar (Zuure 1931).What then caused the separation between the two ethnicities? According to Alphonse Rugambarara the separation of identities came wh en there was a specific political agenda to create separate Tutsi and Hutu ideologies. These terms created animosity and dichotomist identities where there was actually little difference (Rugambarara 1990). The identities of Hutu and Tutsi were so significant that other ethnicities or social segregations became less important. The role of the Hutu as submissive to the Tutsi was engrained in society.An example of this is that in the Kirundi language (spoken by the Hutu) there is not a word equivalent to the English equality or liberty so Hutu’s could not even verbalize a desire for freedom (Lermarchand 1995). Given the strong identity associated with ethnicity in Burundi the complications behind the explanation of the 1972 genocide are understandable. To get to the root of the problem or causes of the genocide is difficult because the perceptions of the Hutu and Tutsi about the conflict are very different (Lermachand 1995). Liisa Malkki studied Hutu refugees in Tanzania who ha d fled from the genocide.She discovered that in the refugee camps â€Å"mythico-histories† were created. These were stories or parables that the Hutu told which constructed their history and moral truths (Milkka, 1989). These stories were not necessarily untrue or true but they served to construct the identity of the Hutu and the cause of the genocide. The Hutu were not the only tribe developing â€Å"mythico-histories. † The truth is very hard to discern among many â€Å"histories† (Lermarchand 1995). Beyond the â€Å"why’s† of the conflict we can conclude the â€Å"what’s. † What actually took place in Burundi in 1972?In the spring of 1972 on April 29th the Hutu attempted a rebellion against the ruling Tutsi. In response the Tutsi retaliated with warfare. Within several weeks roughly 100,000 people were killed in the ethnic conflict. Of the total population of Burundi 3. 5 percent were wiped out (Mikksa 1989). This was not the last of ethnic violence in Burundi. In 1993 the country saw more violence when its first Hutu president, Melchior Ndadaye, was assassinated (Lemarchand 2001). The Hutu reacted to the Tutsi murder of their president by killing an estimated 20,000 Tutsi in the two months following the assassination (Lemarchand 2001).Blame for the violence between the two ethnicities cannot be placed on one group or the other, they are both responsible. The history between the Tutsi and the Hutu is full of attack and reaction sequences. Both the Tutsi and the Hutu wanted to have, â€Å"the last word. † With a long history of violence between Tutsi and Hutu in Burundi there have been severe repercussions. The largest affect of the genocide has been the diaspora of Burundi. The conflict in Burundi created both Tutsi and Hutu refugees in search of safety.The UN Refugee Agency (UN Refugee Agency 2007) estimated in June 2007 that a total of 464,026 Burundians had been displaced from their homes. Of that g roup 48,144 had returned to Burundi and 396,541 were still in refugee status (UN Refugee Agency 2007) Of the refugees still in refugee status, not including internally displaced persons (IDP) the UNHCR is assisting 164,191 (UN Refugee Agency 2007). What exactly do all these terms and numbers mean? Put simply they mean that there are hundreds of thousands of people who were forced or chased away from their homes and livelihoods.The UNHCR defines a refugee as â€Å"a person who is outside his/her country of nationality or habitual residence; has a well-founded fear of persecution because of his/her race, religion, nationality, membership in a particular social group or political opinion; and is unable or unwilling to avail himself/herself of the protection of that country, or to return there, for fear of persecution† (UN Refugee Agency 2007) Under such conditions it is expected that any people group will undergo significant changes. Liisa Milkka has written a book about the ref ugee status of the Hutu’s in Tanzania.She spent one year in Tanzania studying two groups of refugees. Many refugees fled to Tanzania after the genocide of 1972 in Burundi. The first group lived in an isolated refugee camp and the other settled near the town of Kigoma. The town refugees tended to be dispersed amongst non-refugees while the camp refugees were concentrated all in one place (Milkka 1989). Because of these arrangements the town refugees assimilated into the town culture. They took on many identities and did not solely live as â€Å"Hutu† or as â€Å"refugees† (Milkka 1992). Naturally it was more ifficult for the camp people to do the same because they had isolated themselves from the Tanzanians. The camp culture glorified the Hutu identity as the original inhabitants of Burundi who would one day return there to reestablish their kingdom (Milkka 1989). The status of refugee for these camp people was a great thing. It made them become â€Å"a purer an d more powerful Hutu† (Milkka, 1992). These differences between refugee definitions of â€Å"Hutu† complicate the Hutu ethnicity further. Instead of creating more confusion and uncertainty for the Hutu there should be a movement toward unity.This is exactly the approach that the Burundi government has taken to appease the violence between the Hutu and the Tutsi. Instead of stressing differences the government wants to stress unity. By focusing on national unity, democracy, and individual rights the Burundi government has tried to dissolve ethnic tensions (Ndarishikany, 1998). Some discussion has been made about the benefit that could come from reinstating the Burundian abashingatahe (Herisse 2002), which in traditional Burundian society was a judge, moral interpreter and well respected man (Newbury, 2001).The abashingatahe served to reconcile families with communities, certify marriages, settle litigations, maintain peace, and in general speak in favor of human rights ( Herisse 2002). It is argued that bringing this social force back into practice will begin to reconstruct social unity in Burundi. This may be just what the Hutu people need to come together and rebuild. The troubles of the genocides between the Tutsi and Hutu have strained both cultures. Many refugees created by the genocides in Rwanda and Burundi have integrated themselves into foreign cultures.Just an hour to the north of us there are Burundi refugees in the city of Buffalo. These refugees come to the US speaking little if any English. They eventually get jobs and become functioning civilians. As Burundians assimilate into American culture they will eventually lose some of their â€Å"distinct† cultural features. Understanding some of the history of Burundian Hutu’s and the reasons behind the ethnic conflict with the Tutsi can increase the effectiveness with which we help refugees integrate into American society.
