Web-base enterprise applications security guidelines - Research Paper Example Furthermore, the project also provides certain approaches and guidelines that should be maintained in order to ensure security of web based enterprise applications. In the contemporary business environment almost every enterprise have online existence not only for providing information, but also for interacting with key stakeholders such as customers, clients and dealers among others through different web based applications. From online communicating application to electronic investment, enterprises are constantly spawning web based applications that provide increased access to vital information. Currently web based applications are regarded as lifeblood of today’s modern enterprises as they permit employees to perform crucial business activities. When these applications are allowed to access enterprise networks, they can easily share information. Earlier, when the web based applications were developed, the information security strategies were fairly simple to impose, nevertheless, modern enterprises are grappling with numerous security threats. Consumer driven tools have released a new trend of web based applications which can easily be breached and can simply evade the traditional enterprise network security barriers (Fortinet, â€Å"Controlling Web 2.0 Applications in the Enterprise†). As businesses are growing, enterprises are becoming more dependent on web based applications, the complex units are becoming more challenging to secure. Several enterprises secure their network through installing firewalls and ‘Secure Socket Layer’ (SSL) among others, but most of the web-based attacks are focussed on the application level, rather than network level and these security tactics are unable to prevent those attacks. Accordingly, the key motivation for undertaking this study is to devise certain guidelines in order to protect and secure the enterprise network. Additionally, the paper also intends to discuss approaches in order to enhance the

Sound levels - Essay Example There is no doubt that the amount of noise generated in the NICU can be significant. A study at the University of Padova established noise levels within and outside the incubator. It divided those noises into significant ‘white’ noise, and specific noises, which can be used by voluntary and involuntary noises generated when workers touched the plexiglass surface of the incubator, or connected or disconnected to the incubator. It appears that the background noise was less harmful than the sudden and unexpected noises, which tended to generate levels above 80 dB (Benini, 1997). A literature review discovered a good deal of evidence of neonatal stress from noise, with the most common measures being cardiovascular and respiratory response. The authors list the key stimuli, including sound intensity, and the effect that they have on the infant’s behavioral state. Some articles have differentiated the neonates by gestational age and infant maturity. As one of the co-authors found, however, the sample sizes were small, and the variables were not well controlled in most studies (Morris, 2000) Noise has been measured and reported upon in the NICU since the 1970’s. At that time, noise levels were reported in the 70-117 dB range, which is clearly above currently-acceptable levels (Peltzman, 1970) (Long, 1980) (Satish M. a.-S., 1993) (Satish M. S., 1991) . These studies suggested that continuous and elevated noise levels resulted in significant deterioration in healing and levels of nervousness in neonates. Early work on the effects of noise in the NICU concentrated on noise within the incubator itself; these led to improvements in incubator noise reduction, and resulted in a general emphasis on NICU noise reduction (Bess, 1979). It is always difficult to find accurate, reproducible responses of newborns to stimuli. One effect which can be reproduced is that of reduced noise on sleeping times for infants. Strauch et al led a study which

For example, regarding offices one would have elections (an oligarchic element) but no property assessment (a democratic element). Montesquieu agrees in part with Aristotle’s ideas of combining a democracy with oligarchy. He terms them â€Å"executive† and â€Å"legislative† branches, but they are in effect the same as Aristotle’s â€Å"democracy† and â€Å"oligarchy†. Montesquieu echoes Aristotle’s arguments that having the mixture of the traditional governing bodies would balance the power and authority. Further more, he references Aristotle in his book by saying; â€Å"The inhabitants of a particular town are much better acquainted with its wants and interests than with those of other places; and are better judges of the capacity of their neighbors than of that of the rest of their countrymen. The members, therefore, of the legislature should not be chosen from the general body of the nation; but it is proper that in every considerable place a representative should be elected by the inhabitants† (Montesquieu). Aristotle, Montesquieu, and Locke all support the notion that civil society originates when, for the better administration of the law, men agree to delegate legal functions to certain officers. They are all against a â€Å"monarchy† government as it does not support a civil society. It by definition corrupts the individual who is given all of the power. Both Aristotle and Montesquieu allow for a balance between the oligarchy/monarchy and the democracy by allowing an â€Å"executive† element who’s function is to balance that of the legislative/democratic element. 2) Aristotle believed that there were three classes. At the bottom were the farmers, laborers, and poor. As this class of people did not have the leisure time to pursue education, they would make a meager ruling class. The ruling class Aristotle argued should be comprised of the leisured classes, and the â€Å"middling element†. He clarifies that the

Race and Nation in the Twentieth Century Essay Example | Topics and Well Written Essays - 500 words

Race and Nation in the Twentieth Century - Essay Example Civic nationalism can be said to bet that particular type of nationalism that define a country as a room where individuals associate with same levels of political rights that are evenly distributed to each other (Gerstle, 2001). In this association, the members are assured to allegiance to the same political methodologies and guidelines. This particular type of nationalism has the underlining principle that the nation is not guided by individuals with same ethnic ancestry, rather a political entity without the core of ethnicity. Civic nationalism is therefore the form of nationalism whereby the government draws legitimacy of political grounds from its citizen’s active participation, hence representing the will of its population. Racial Nationalism refers to global approach and view, which makes a combination of the love and passion of an individual’s race together with the love and passion an individual nation. By combining the two elements of love and passion for both one’s race and nation, this particular view advocates for a self-determination perspective for all the world races. In the American context, this view became very practical when it comes to matters pertaining to the uniqueness characteristics of each race and their preservation as well. In America, this view emerged advantageous by eliminating the opportunities for one group to exploit the other (Gerstle, 2001). Soft Multiculturalism refers to a condition that had already existed before in the United States and Europe, among other nations, due to the real availability of a number of cultural and religious associations. They also include other individuals who have migrated into these countries. In the United States of America, Soft Multiculturalism got related to the development some futures that were close distant. Those individuals initiating these developments must prepare

Review Coursework for Rules for monetary policy questions

Review for Rules for monetary policy questions - Coursework Example However, the excessively high level of money circulating in the economy induces inflation. Conversely, the excessively low level of money circulating in the economy kills economic performance and induces deflation. Since the association between the money supply and other economic indicators such as the gross domestic product and prices level or inflation has become irregular, the money growth based policies have been unsuccessful (What is money supply? Is it important?, 2014). Adopting rules for the monetary policy is like suggesting that the economy regulators clearly understand all the variables within the economy and how they affect one another. The center stage for the formulations of rules for monetary policy is the interest rates and the economic output. It is currently clear that the performance of an economy is influenced by the performance of other institutions like the financial market, the capital market, and the financial institutions. These players add to the list of factors to be considered when formulating rules for monetary policy. The regulators have not been able to understand fully how the financial markets affect the economy, thus, controlling an unclear situation could cause damages. Therefore, the policy makers are reluctant to adopt rules for monetary policy (Swanson, 2014). Swanson, A. (2014). What the US could gain and lose from monetary policy rules. Retrieved from

The Holy Virgin Mother Mary Essay Example for Free

The Holy Virgin Mother Mary Essay The Holy Virgin Mother Mary,by Chris Ofili, is one of the many controversial pieces of artwork to rise to fame in the late nineties. Taken as highly offense to the religious community due to the portraits exposed breast, hints of pornographic material,elephant dung and seemingly downgrading use of the sacred image of Mother Mary. Due to Ofilis inappropriate interpretation of real art, he received countless criticisms about his work including threats and vandalism against The Holy Virgin Mother Mary. The portrait has a 2D shape,very flat with little to no depth. My eye is drawn directly to the blue rosebud in the center of the portrait,which turns out to be the breast of the Holy Virgin Mary,after reading a little into the background of this portrait. Multiple round putty-like splatters are spread out around the painting. If you look closely you can determine that these are pornographic cutouts pasted all along and around the painting. The foreground of the painting tends to blend with the background and the only thing separating the Virgin Mary from the bright yellows and oranges is a soft thin line. The Holy Virgin Mary depicts a woman of African descent and clothed in turquoise blue robes in a similar manner as mother Mary. Small round objects float about the painting in a random and unorganized manner,which represents an ironic reference to the putti that appear in traditional religious art. The Holy Virgin Mother Mary sit centers around a yellow and orange background. Ofili started using dried-out elephant dung for the first time after a visit to Zimbabwe in 1992, his first ever trip to Africa. He was so taken by this experience that he wanted to import something of the African landscape into his paintings. In order to compensate for the foul nature of the dung, however, he took special care to make the overall effect of his paintings especially attractive. He did so by making richly-layered decorative surfaces. Ofili employed mixed media, including oil paint, glitter, and polyester resin,and collaged pornographic images in this painting, incorporating colored dots, sparkling glitter, polyester resin, map pins, collage cut-outs, all carefully combined into a dazzling display of vibrant folksy energy. A lump of dried, varnished elephant dung orms one bared breast, and the painting is displayed leaning against the gallery wall, supported by two other lumps of elephant dung, decorated with colored pins. The pins on the left are arranged to spell out Virgin and the one on the right Mary. (BBC News) In an interview, the British artist Chris Ofili discusses his work. He asserts that his paintings are part of hip-hop culture, and states that his work operates on multiple levels and is open to interpretation. He explains his intention of transforming everyday junk and aspects of contemporary culture into thought-provoking images, noting the importance of his identity as a Londoner. He discusses his techniques and current projects, and explains the importance of music, drawing parallels between his concerns and those of contemporary hip-hop and soul artists. He considers his painting The Holy Virgin Mary with reference to issues including the stereotyping of black women, the paradox of the virgin mother, and notions of beauty and caricature, and concludes by asserting that art can be constructed from anything and should be unrestricted by cultural norms(Miller, Paul D). It is perhaps Marys role as virgin and mother that best captures the paradoxical character of her identity and her imagery. Mary has often been cast as the counterpoint to Eve,as the agent of sin and death versus woman as vehicle of redemption. Yet, remember, Mary also bore a son. In one fourteenth-century book, the Annunciation scene is surrounded by cats, rabbits, monkeys, and flirtatious girls and boys to contrast the Virgins chastity with worldly carnality and simultaneously to offer a message of fertility(College Street Journal). I think that Ofilis imagery must be seen against this,contradictory visual history and in terms of the personal and universal that has underlain much of art connected with the Virgin. Ofili depicts her features and uses elephant dung to connect her in a basic way to the African earth and its people. To depict the The Holy Virgin Mary as a beautiful piece of art, is a bit of a stretch for me. It is a unique work of art that expresses the artists views on certain religious phenomena and worldly stereotypes.

A History Of Dna Typing And Analysis Criminology Essay

A History Of Dna Typing And Analysis Criminology Essay The discovery of DNA typing has changed the way crimes are investigated. DNA evidence can be found in blood, tissue, hair, saliva, semen, bone, and the list goes one and on. Every person has unique DNA with the exception of identical twins so being able to interpret this valuable information is incredibly useful. Without DNA typing this evidence could not be tested and interpreted. Many criminal cases would go unsolved and people who committed these crimes would still be unpunished for their actions. DNA typing has only been around since the mid 1980s, but has already had a big impact on the world. So, how did the remarkable tool come about? DNA typing is the use of DNA evidence for identification. The DNA evidence found at a crime scene can either link a person to a crime or it can eliminate them as a suspect. It is based on the observation that the genome of each person and animal is unique. This technology has only been around since the mid 1980, but it has already become an essential part of the crime laboratories investigation of a crime. DNA evidence can be stored for long periods of time making old cases that were once thought to be unsolvable now have new leads. Also DNA evidence can be used to exonerate wrongfully convicted prisoners. DNA typing can be classified into two categories; restricted fragment length polymorphisms (RFLP) methods or Polymerase chain reaction (PCR) methods. In 1985 an English geneticist named Alec Jeffreys first described DNA typing. Dr. Jeffreys was attempting to trace genetic markers between members of the same family. He was specifically looking for inheritance patterns for illness and disease. X-rays of mini satellite sections of DNA were taken and examined. On September 10, 1984 Dr. Jefreys was examining several x-rays and noticed that the mini satellite section of each individual was unique from one person to another (web.mit). He developed a technique to measure the difference in the length of the DNA sequences. This allowed him to perform human identity tests. The technique Dr. Jeffreys created to examine these variable number of tandem repeats (VNTRs) was called restriction fragment length polymorphism (RFLP) (Butler). Restriction fragment length polymorphisms are variation in the length of a stretch of DNA. DNA is cut by restriction enzymes and these pieces of DNA contain genes and non-coding DNA. The non-coding DNA is made up of regions of repeats of the same sequence of bases. These multiple regions are known as variable number of tandem repeats (VNTR). To develop a DNA profile-using RFLP is to first extract the DNA. Then cut the DNA into fragments by using restriction enzymes. Once the DNA is cut into fragments they are separated by size using gel electrophoresis. The fragments are then immobilized by transferring them into a nylon membrane. The fragments are identified and located by using a solution that contains the desired probes. To visualize the fragments requires long exposure to detection system. This step involves the probes specifically binding to their complementary VNTR fragments. After the solution is washed the RFLP profile is visualized (Butler). Many crime laboratories adopted t his method of analysis and used it throughout the rest of the 1980s and for most of the 1990s, but there were some disadvantages to the RFLP analysis (Budowle). The process takes a lot of time and a lot of effort to. A large sample of un-degraded DNA is required to perform the test. The first time DNA typing was used in a criminal case was in 1986. In the village of Narborough in Leicestershire, England two girls, Lynda Mann and Dawn Ashworth were sexually assaulted and murdered. The murders were done in a similar fashion leading to the suspicion that the two cases were connected in some way. One man confessed to the murder of a girl, but his DNA did not match that of the DNA recovered form semen found at the crime scenes. Blood was collected from more the 4000 men from three surrounding villages. The blood sample collected from Colin Pitchfork match the semen from both murder scenes. He was convicted of both murders and was sentenced to life in prison (Wambaugh). DNA typing evolved from the use of Dr. Jeffreys method of analysis to the use of single locus variable number of tandem repeats by RFLP analysis. DNA typing then moved to the use of polymerase chain reaction (PCR) that was more sensitive, easier to perform, took less time, and can be automated. In 1983 Kerry Mullis discovered the polymerase chain reaction (PCR), which he later won the Nobel piece prize for. This development revolutionized forensic DNA analysis. PCR is used to amplify selected sections of DNA that contains either length or sequence polymorphisms. The DQ-Alpha test was one of the first PCR test to be used in crime laboratories. The DQ-Alpha test was developed in 1991 and was based on the identification of human leukocyte antigens, which are proteins that have a known sequence. The next innovation was developed later in the 90s with short tandem repeats (STR). Short tandem repeats are kind of like VNTRs, but with very short sequences that vary from two to six base pairs . The advantage of using this method is that very small amounts of DNA are required to perform the test (Butler). DNA profiles are also very useful because they can be electronically entered into databases. The Combined DNA Index System or CODIS is a collection of databases of DNA profiles obtained from evidence samples from unsolved crimes and from known individuals convicted of particular crimes (Butler). The FBI who oversees the database started CODIS in 1998. The main goal of the CODIS system is to allow local and national law enforcement laboratories to be able to compare DNA profiles to each other electronically and to be able to link crimes to each other. The system is made up of three database levels: local, state, and national levels. The convicted offenders index qualifications for submitting a sample are determined by state legislation. Convicted offender profiles make up most of a states database. The forensic index is the second most common entry. Forensic profiles consist of forensic evidence in cases. There main purpose is to generated leads in the investigation and possibly conne cting cases to each other. Some states are required to maintain other indices such as a suspect database The National DNA Index currently contains more the seven million offender profiles and almost 269,000 forensic profiles. CODIS has produced over 90,900 hits and has help solve more than 89,600 cases (Butler). DNA analysis has evolved of the past twenty-five years and now it can be used in many different ways. A big way in which DNA is used is in the identification of individuals in mass disasters. One example is the September 11th attacks on the World Trade Centers. DNA was collected from the bone and tissue the unknown bodies, put into a database, and compared with reference samples that were collected. Only 1585 of the 2792 known deaths have been identified, but the database was reopened in 2007 and further investigations are going on. Another effort to identify unknown victims in the DNA Shoah Project, which is a database of family members of people who were in the Holocaust. The main effort of the database is to reunite families who were separated and help identify buried Holocaust victims. DNA analysis isnt just used in solving criminal cases or identifying unknown people, it is also used to check and see if something is authentic. The National Football League uses DNA technology to mark balls used in the Super Bowl to ensure authenticity and stop counterfeit merchandise. The football is marked with an invisible strand of synthetic DNA that can be read by a special laser. A similar thing occurred in the 2000 Olympic games. DNA was taken from unknown athletes and added to ink that was used mark all of the official Olympic gear (DNA Forensics). Without this remarkable tool many of the criminal investigations going on right now would go unsolved. According to Locards Exchange Principle every time a person enters any kind of environment something is left behind and something is taken away. This means that every time a criminal enters a crime scene evidence is left behind and evidence is taken away. An example is a criminal leaves behind fingerprints, pieces of hair, or semen behind at the crime scene. The offender also takes away hair and possible blood from the victim on his clothes or shoes. Without DNA typing this evidence would not be able to be linked to the crime scene. There have also been several cases were DNA evidence has been used to pardon the wrongfully accused. As the technology becomes more advanced and new methods of testing DNA are being created DNA typing will continue to revolutionize the way criminal investigations are solved as well as the creation of more new and exciting ways DNA can be used.
