Security in New Generation Cell Phones Research Paper

Security in New Generation Cell Phones - Research Paper Example Technology in every new generation provides major improvements from the previous generations. In the cellular communications, there was first the 1G and 2G generations. These generations contributed to the provision of the internet for the mobile phones through the 3G dominated the scene. The third generation cell phone internet had advancements that made it stand up from the earlier versions of 1G and 2G. The 3G had the capacity to converge voice and the data with the wireless internet. This makes it suitable for transmitting data in high quantities. Additionally, migration towards the 4G technology has been witnessed. Regardless of these processes and developments, the security of cell phone remains paramount. Ensuring the security of the cell phones The continuity in the manufacturing and distribution of cell phones leads to the rise in the security risks in different ways. Users of electronic gadgets like cell phones should be more concerned about their safety. Lately, electronic devices such as the Apple’s iPhone latest version and the Google’s Android have committed themselves to the manufacturing and development of cell phones with 3G networks so that they possess the same features and functions of computers. Although this promotes great conveniences, it also comes with severe security risks. Both the new and future generations of cell phones require the setting up and update of security software. This software includes firewalls, anti-virus software, operating system patches, anti-spam software, file encryption, and the anti-spyware software. This requires the observance of the basic home computer internet safety and guidelines. The revolution in the field of information technology has enabled most financial institutions to adopt mobile banking technologies to enlarge their customer bases. Cell phones users are required to conduct their business and financial transactions online. As a result, they will need to store their login passwords w ith the information pertaining to their credit card and personal details. With this trend, there will be more cases of online fraud, identity theft, more spam, digital forgery, data theft, and any other cyber crimes. Besides, it can also lead to the denial of disseminated service attack. This has the risk of disabling the network service supplier. Additionally, cell phones are prone to theft based on their portability compared to desktop computers. Since most theft cases occur unexpectedly, a cell phone user can lose a lot of information and data stored in the mobile device. In the event that the mobile device contains business and financial information of the user, the thief can use it to defraud the user of his or her finances. This is a major security concern. Additionally, the new generation cell phones come with applications that display the user’s location and movements. One such application is the opt-in text advertisements that give information on the whereabouts of t he user round the clock. Hacker stalkers can use this information to trail their victims and even do felony acts to them.

Peruse some sources to find a relationship between dress codes and success in the work place. Remeber to focus on anglophone cultures - Essay Example This is because an organization’s image is represented by its employees, with outstanding expertise and academics, one’s appearance lay the foundation for perceptions; internal as well as external (Howard, p. 234). Eventually, appearance plays a great deal in one’s success. Dressing in a work appropriate manner portrays one’s seriousness towards their job. If the employer doesn’t dress appropriate, employees would not see him respectfully. Dressing appropriately shows good work ethics, mainly because employees are meant to display a professional image to the clients and customers. Although, dress code provides an opportunity for self-expression, but wearing things inappropriate can hinder the success level (Neil, p.279). Furthermore, certain criteria should not be ignored while dressing for work, like cultural aspects and nature of the job. Organizations give peculiar guidelines regarding dress code to help their workers verify what constitutes fitting and agreeable work environment clothing. In accordance with the Anglophone culture: a suit and wingtips would look perfect on a financial analyst; while it might look out of place on a telephone operator. In the same manner, a professor cannot go to the class wearing miniskirt, or gowns or really casual clothes. Several studies have shown that looking good from outside can make one feel good inside, which is why it is also vital to take care of employees’ comfort. Many companies also have pretty impressive dress code policies, designed in a way that allows employees to have a professional image, as well as respecting the comfort and style element intact. On the other hand, there are companies with formal dress code policies and documents with specific instructions prohibiting women from wearing certain pieces of jewelry and men from wearing cufflinks or sneakers (Workplace Law Handbook, p.179). Guidelines provided by companies for dress code and attire correspond with several factors, such

Morris, note on sculpture Essay Example | Topics and Well Written Essays - 500 words

Morris, note on sculpture - Essay Example He was in the forefront of art movement in America which included process art and land art. His major works included â€Å"notes on sculpture†, anti-Form, creation of minimalist key exemplars like rectangular beams and cubes which had no figuration. I would characterize Morris’ status in art history as an influential art personality who changed the industry of art. This is due to his works that introduced indeterminacy and temporality in the field of art. According to Morris, (3), Morris defines the most fundamental components of sculpture as to include: mass which has to do with the bulk of the sculpture. This is important because it defines the sculpture’s edges the second one is space. This is that air around the given solid sculpture. It is important for linking separate sculpture parts and defines the sculpture edges. Additionally it can provide areas of emptiness in the sculpture when enclosed by a part of the very sculpture. Color, dimension, flatness and texture may also be some important elements of a sculpture including shape. Gestalt is a term used to refer to a pattern or configuration of elements that are unified as a whole. As such it implies some pattern. Morris used pyramids, cubes and polyhedrons that are regular to achieve this. He asserted that this forms when used can result in to one achieving a very strong sensation of Gestalt. Gestalt, thus he described to be patterns or even configurations that the whole is considered to produce greater significance that is better than when the parts are individually considered and are also different. Gestalt is generally the pattern brought by the whole and not an individual piece of the whole. Indeed Morris claims that sculptures exist in a situation and not as self-contained forms. This he asserts by arguing that sculptures communicate situations that the artist needed to depict (Morris, 17). As

Tay-sachs disease Case Study Example | Topics and Well Written Essays - 1250 words

Tay-sachs disease - Case Study Example The type of information that the Trosacks would get from each member would definitely be markedly different. For example, the nurse would probably be available in a capacity that was strictly in order to help Mrs. Trosack learn more about her pregnancy and the practical issues that might arise with the responsibilities she were to accept the challenge to be a mother to a Tay-Sachs child. In terms of the geneticist, the geneticist would be able to logically explain why their unborn child has Tay-Sachs, not to mention how he or she would genetically break down the facts in order to help explain to the couple about how the recessive gene on the paternal side needs to be available for both parents to be carriers. The doctor would probably talk about the main effects of the illness on the child and what kind of treatment would be needed. The chaplain would be available for moral support. 2. Teaching Plan For the Trosacks’ Initial a. Genetic Diagnosis The diagnosis of Tay-Sachs is, fortunately, one clear-cut fact. According to NINDS Tay-Sachs Disease Information Page (2011), â€Å"Patients and carriers of Tay-Sachs disease can be identified by a simple blood test that measures beta-hexosaminidase A activity. Both parents must carry the mutated gene in order to have an affected child. [Given these circumstances, usually] there is a 25 percent chance†¦that [their] child will be affected with Tay-Sachs†¦Ã¢â‚¬  (pgh. 2). b. Treatment The treatment of Tay-Sachs is probably going to be aggressive in nature.

School Uniforms Essay Example for Free

School Uniforms Essay sCHOOLMany schools across the nation enforce students to wear school uniforms. While school boards feel that they are better for the students, many parents and students disagree and feel that not only are they outdated, but should be banned. School uniforms are an outdated habit and they should be banned because they don’t allow expression, they may make students feel uncomfortable, and they don’t guarantee safety of the students. Enforcing school uniforms along with the schools settings restrict students from wearing the style of clothing of their desire. Students lose their freedom to choose and right of personal expression. Losing these rights may cause students to retaliate in extreme ways using piercings, extreme hair styles, and even tattoos. John Adams Middle School in Los Angeles, California requires their students to wear uniforms. Most students felt that the uniforms were restricting of their personal style and that the dark blue bottoms were dangerous because the color could be mistaken to be part of a gang, or involved in something that is gang related. School uniforms causing students to dress the same every day, along with dressing like everyone around them, may make students feel uncomfortable in their own skin. Students can also lose confidence in their appearance because the uniforms are plain. Forcing school uniforms may depress students and it may impair their academic performance causing grades to fall. â€Å"When you’re young you hate the fact that you have to dress like everyone else because you feel like each person is different and each person has their own style. I personally didn’t like uniforms in high school but only because I was forced to wear them and there was no way for the guys to make it their own style like the girls†. (Davis) Another fact is that school uniforms don’t always guarantee safety. If a school enforces uniforms, it’s easier for intruders to blend in and potentially take over the school with weapons and injure students and faculties. Also, they don’t prevent bullying because the uniform itself won’t keep one student from picking on another student, and it may cause students to pick on others even more if their uniform is even a hint off. â€Å"When I was in school, we had to have green pants, and my mom couldn’t afford any so she made me a pair. On the first day of school my teacher made me stand in front of the whole class as an example because they were the wrong shade of green. The rest of the day I got picked on and laughed at by the other kids. † (Matthews) Students from wealthy families have valuables including smart phones or expensive jewelry. While school settings provide protection from damage and theft of clothing, they do not provide protection of personal items. Katelyn, a student at John Adams Middle School, at a point in time received a pearl necklace, and a ring that was passed down from one generation to the next. While at school, in P. E. a group of girls were going through personal belongings in the locker room. The jewelry was stolen and the school refused to pull all of the students to check for the missing items. School uniforms blocks the self-expression of students, makes them uncomfortable, and doesn’t guarantee 100% safety. Bullying can, and more than likely, will still take place among high school students. If students continuously dress the same, they may feel as if teachers and faculty want everyone to be the same, and they may feel uncomfortable with being like everyone. Blocking a student’s self-expression can lower their self-esteem and they may feel like no matter how hard they try they will never be good enough. Works Cited Davis, Chad.

Thomas Jefferson and Sally Hemmings

Thomas Jefferson and Sally Hemmings Sally Hemmings was the daughter of Elizabeth Hemmings. Sally was born in 1733, most people thought she was mulatto. A mulatto was a common term used during slavery when an African American slave and white person create a relations. Most people asked why she had power over Thomas Jefferson. But her family and friends were just trying to make sure that she was being well taken care of by Thomas. It was very possible that Thomas could lose his job for carrying a relationship with a slave. Sally was considered a pampered slave, but she got what she wanted for her children. Was their mixed marriage relationship and mistake? If one were to have an interracial relationship it would be kept in the dark from society or a consequence was paid. After the death of John Wayles and Martha Wayles which was sallys parents. Thomas Jefferson inherited the ownership Hemmings family and moved all of them to Monticello when he lived there. That would be known as the new residence for the Hemmings. The place where the two had met. Some speculate that due to their kinship, Hemmings and Martha Jefferson may have looked very similar which could have been a key factor in Jeffersons attraction to Sally Hemmings. Since there is no factual evidence in writing from either Thomas Jefferson or Sally Hemmings, many people relied on other family members writings and used assumptions to draw conclusions about their relationship. Till this day, many people still have inconclusive evidence about their relationship and why it lasted a long time. Sally made the decision to continue a long term relationship with Thomas Jefferson, after a heavy evaluation of her options, her conditions and the little empowerment she had over Thomas Jefferson. Although Thomas Jefferson was a founding father of the United States of America, he was still human. That being said, Jefferson could have committed the act of having children with one of his slaves Sally Hemmings. Due to the evidence given, this is known to be true. The light treatment of the Hemmings family, the emancipation of the Hemmings family, and Madison and Eston Hemmings accounts of claiming Thomas Jefferson as their father are all reasons that point to the fact that Jefferson indeed fathered the children of Sally Hemmings. Thomas Jefferson often treated the Hemmings family lightly, or without a big workload. As it is stated in A Brief Biography of Sally Hemmings ´ Sallys son Madison recalled that one of [Sallys] duties was to take care of [Jeffersons] chamber and wardrobe, look after us children, and do light work such as sewing. ´(A Brief Biography of Sally Hemmings ´) Along with the light workload, she was also paid occasionally a monthly wage of twelve lires. ´( A Brief Biography of Sally Hemmings ´) This small payment and light workload signifies that Jefferson had some emotional ties to Sally considering he did not pay his other slaves anything. Of all the slaves that Jefferson owned, it is not recorded that any of them received special treatment other than teemings family. Thomas Jefferson treated Sally well as she was his daughters nurse throughout her life. While Jefferson was in France, it is recorded that Sally was sent to France to accompany Martha and Maria Jefferson. It is said by Madison Hemmings that during that time [in France] my mother became Mr. Jeffersons concubine and when he was called back home she was enceinte by him. ´ ( ³The Memoirs of Madison Hemmings ´) Madison Hemmings also stated that soon after their arrival [from France] (Memoirs of Madison Hemmings ´) Not only did the Hemmings family receive light treatment, but they were the only slaves of Thomas Jefferson to be emancipated by him, with the exception of one of his body servants. Israel Jefferson a slave of Thomas Jefferson stated that [Jeffersons] death was an affair of great moment and uncertainty to us slaves, for Mr. Jefferson provided for the freedom of seven servants only; Sally, his chambermaid, who took the name Hemmings, her four children. Beverly, Harriet, Madison, and Eston, John Hemmings, brother to Sally, and Brunel Colburn and old and faithful body servant. Never emancipated any slaves but hose of the Hemmings family. Other than being the concubine or kin of Thomas Jefferson, there was no reason that Thomas Jefferson would emancipate his slaves according to his life as a slave owner. Jefferson clearly wrote in his will that the Hemmings family be free of their slave bond a great a certain age, most likely the age of 21. Another piece of evidence that Jefferson fathered children by Sally Hemmings is the accounts that  ³Both Madison and Eston Hemmings made known their belief that they were the sons of Thomas Jeffer son. ´(A Brief Biography of Sally Hemmings ´) In  ³The Memoirs of Madison Hemmings, ´ Madison refers to Thomas Jefferson Directly as  ³father ´ six times when he writes of him. Madison grew up with Thomas Jefferson as his father and continued to follow this belief throughout his life.  ³We were the only children of by a slave woman proclaimed Madison. This particular statement assures that Jeffersons relationship with Sally and her Children relates to their emancipation in Jeffersons will. Madison and Eston Hemmings are not the only accounts of assurance that they are Jeffersons children. Israel Jefferson also gives assurance that Thomas Jefferson was, in fact, the father of Sally Hemings children. In his memoir I also know servant, Sally Hemmings was employed as his chambermaid, and that Mr. Jefferson was in the most intimate terms with her; that, in fact, she was his concubine. This I knew from an intimate relationship. Sally can conscientiously confirm his statement as any other fact which I believe from circumstance but do not positively know. Thomas Jefferson was by no doubt the father of Sally Hemings children. The relationship between Thomas Jefferson and the Hemmings Family was not a coincidence. Jeffersons acts were only proof that he was human. Many other great men in history have had similar stories to that of Jeffersons. Thomas Jefferson was the father of Beverly, Harriet, Madison, and Eston Hemmings as evidence of the light treatment and emancipation he gave to the Hemmings family and the memoirs of the Hemmings family and Israel Jefferson. Was it true was the question most people asked In 1997, Dr. Eugene Foster, a retired medical professor, began investigating the possibility of a genetic link between living descendants of Thomas Jefferson and those of Sally Hemmings. He compared the blood from five descendants of Field Jefferson, Thomass paternal uncle, with the blood of the descendants of Sally Hemmings, Thomas Woodson, and the Cars. The DNA was extracted from the blood samples at the University of Virginia, then sent to Oxford, England where it was tested by three different laboratories. The results showed a match between the Y chromosomes of the Field Jefferson descendants and the Eston Hemming descendent, providing strong support to the theory that Thomas Jefferson fathered at least one of Sally Hemings children. The chances that this match happened by coincidence are less than .1 percent. Was the case closed? A claim that most Jefferson scholars had earlier considered so implausible that nearly all of them rejected it without a truly rigorous investigation-has gained new credibility and extensive national publicity. In 1997, law professor Annette Gordon-Reed reviewed the evidence and concluded that the case for Jeffersons paternity was much stronger than scholars had supposed. In 1999, DNA tests proved compatible with the possibility that Jefferson had fathered Eston Hemmings, Sallys youngest son. The DNA report, a conference held at the University of Virginia, a volume of essays resulting from that conference. Madison Hemmings, another of Sallys sons, said that he and his siblings were Jeffersons children (and his only slave children) in a report which accords in much of its substance with other sources. According to this interview, Thomas and Sally initiated an affair while they were together in Paris from 1787 to 1789. Sally became pregnant and agreed to return to the United States after they entered into a treaty in which Jefferson promised extraordinary privileges for Sally and freedom for her children when they reached age 21. Some very interesting facts would be Madison Hemmings, another of Sallys sons, said that he and his siblings were Jeffersons children in a report which accords in much of its substance with other sources. According to this interview, Thomas and Sally initiated an affair while they were together in Paris from 1787 to 1789. Sally became pregnant and agreed to return to the United States after they entered into a treaty in which Jefferson promised extraordinary privileges for Sally and freedom for her children when they reached age 21. A supposed resemblance between Thomas Jefferson and some of Sally Hemmings children (or other Monticello slaves) is hardly evidence of a very substantial kind. A resemblance is often seen by some observers and denied by others. Later in life by 2003 there was a book published the attorney/historian, Annette Gordon Reed, published a book on Thomas Jefferson and Sally Hemmings, The Hemmings of Monticello: An American Family, a follow-up to her 1998 book, Th omas Jefferson and Sally Hemmings: An American Controversy.
