The Voice of a Writer Essays

The Voice of a Writer Essays The Voice of a Writer Essay The Voice of a Writer Essay My style of writing is a depiction of my thought process. When reading something Vive wrote, while it may take you awhile to get through it all, contains limpness of my life, sarcastic comments, and generally a lengthy beginning. All of these aspects bring a little of myself into my writing, which creates an overall genuine tone that ties everything together. My family is super goofy, cracking Jokes day and night. That environment growing up shaped my personality, hence, influences my style of writing. I make use of sarcasm to not only put some of myself into my writing, but also to give a personal feel to the words, making them more relatable and believable. As Allan Sloan said, l talk that way, so I write that way. Although, my sarcasm may not transfer as well on paper as it would in person, I try to keep everything I type on the keyboard, or scribble down on a piece of paper with the intention of the reader thinking, MIPS, thats something Emily would say. Reading a paper of my mine is the equivalent of having a face to face conversation with me, because who I am as a writer is the same as who am I as a human being. Basically, I like to have a sense of life in what I write, and these lifelike characteristics create the genuine tone, essential for a good work of writing. Personal touches in a piece of writing, to me, are one of the key components to making a successful representation of your thoughts, no matter the effect youre trying to achieve. Persuasive, informative, reflectiv e, all need feeling to be successful in grabbing the readers attention. Whether youre trying to persuade your mom to let you go to the movies or get a man walking down the street to stop and read your article about politics, you need a level of pathos, appeal to the readers emotions, to truly gain their interest and win them over. The quote, My ideas usually come not at my desk writing but in the midst of living. As told by Nanas In is a metaphorical representation of how I use my life experience to Justify my thoughts. When you can appeal to someones emotions, you create a level of better understanding for the reader. When you read my writing, youll notice Ill reference past experiences, people I know, personal decisions, etc. All because it creates a conversational tone. Its like a glimpse into my life that others can read and think about a similar situation that has occurred to them. When you can relate to someone, it makes the task of being assured the reader understands your points much easier. Even if the reader doesnt agree with what youre saying, they can respect your thoughts. I view my writing as a creative process, one in which I usually experience as I go. Joan Doing said it best in his quote l write entirely to find out what Im thinking, what Im looking at, what I see and what it nearness. which is a clear explanation of myself while writing. My writing is my Test way AT putting my tongues together, ten majority AT want I write Is a pretty accurate representation of my thought process. A lot of times, I write an entire piece before I go through and read it. I write before I even give myself the chance to think about it because if I do, I will lose the thought and be back to square one. As Im writing this now, I dont know if it makes sense, is relevant to what I should be describing, or if it even has a type-o. My thoughts are composed through my writing, and my creation is the result of finding what my meaning is. The two above images go hand in hand, but in a way that they both represent different portions of my writing process. Going back to the idea that my writing is a mirror of my thoughts, my mind while Im writing is constantly throwing ideas, words, ND sentences to me which I write down so, in turn, my writing tends to get pretty lengthy. While length of an essay is an important component, I believe that quantity is not to be confused with quality. My mind gets so wrapped up sometimes on one particular subject that sometimes I spend too much time on one topic and do a poorer Job on other points I want to get across. Timed essays are probably one of my biggest challenges, the typical style youll see is long, descriptive first few paragraphs, but the last paragraph may be only a few sentences, sometimes its as bad as to not even have a conclusion. This is one of the flaws my writing possesses, and these pictures depict that: my attitude at the beginning of writing is like that of the first picture, but my expression as time runs short and I rush Just to finish, well Im sure you can gather from the ladder. To fully understand anything requires a level of evaluation, sometimes even going as deep as to self-analysis. Before I typed up this conclusion, I went back through and read the three some-odd pages I had schemed up, analyzing my analysis of myself. And what I concluded is all too shocking: I have proceeded to categorize myself as a writer. Vive always considered writing my best subject, and in doing this paper, Vive come to understand the fundamentals of the subject I personally excel at, making the future works that much better because pointing out the key components demonstrate what makes my writing truly mine, and ultimately myself as a person. The overall theme of my writing is personality: my unique qualities being portrayed through words sometimes carelessly thrown on a page while containing specific stylistic qualities, such as long descriptive beginnings followed by short and choppy conclusions (other than this one of course).

Systems Programming - Essay Example In order to protect digital information, organizations are keen to implement technical controls such as firewalls, Intrusion Detection Systems, honeypots and Demilitarized zones. These controls are considered as logical and provide security on the logical layer. However, often the important aspect i.e. information security management is not addressed to the optimal level. A typical information security program is led by an information security manager who establishes a steering committee for discussing security aspects focusing not only the IT department but every department within the enterprise. Some of the management controls that are implemented by the information security manager are IT governance, Risk management, monitoring Key Process Indicators (KPI) and Key Goal Indicators (KGI). KPI demonstrates the current state of security within an organization and KGI demonstrates the level of security to be achieved. As per the current scenario, critical data must be protected by impl ementing Firewalls to secure the network from external logical threats and Virtual Private Network will be implemented for securing the data transmission on the Wide Area Network. The modern operating system introduced by Microsoft is named as Windows 7. This operating system contains advanced tools for network security from viruses, malware and spyware thus reducing the security breaches and risks. Another feature Windows 7 comprises is an enhanced backup solution for the important data. This will also provide more control via parental tool to protect family from possible risks. The Windows 7 also includes enhanced protection, safety and privacy characteristic for better internet experience. 2 What security is all about The Windows 7 incorporates a tool named as an Action Centre that allows the users to check firewall updates, software’s updates such as antivirus. Furthermore, this Action Centre will automatically turn on for all the latest available software updates. This A ction Centre is located in Control Panel for easy access for the users. 2.1 Protect your data from theft, hackers and accidental loss Another new feature that is included in Windows7 is the BitLocker Drive Encryption. This allows your Windows to encode all the important data, passwords and other information stored in the hard disk. The data encodes automatically into the hard disk as soon as the BitLocker is activated. Similarly, firewall also plays a vital role in computer protection. The firewall is designed to block all the unsafe data or malicious soft wares that enter into computer. The firewall present in Windows 7 is made more flexible and easy to use to provide maximum protection against hackers. In Windows 7, the backup system is also enhanced and made user friendly.

Voice over Internet Protocol Security Vulnerability and Risk Analysis Literature review

Voice over Internet Protocol Security Vulnerability and Risk Analysis - Literature review Example In modern times different means and mechanisms are being introduced for establishing communication with one another. The aim behind all of them has been to work on those lines that ensure reliable, fast and economical sources that can enable connecting people from across the borders and shores. The progress so made is so immense that people sitting across the continent can get in touch and see each other in matter of few seconds. Different means exist for such concepts. All those means of communication that have existed in history were conducted with a concern and consideration of privacy in them. This is achieved through encryption of data that is being exchanged between the two points. Voice over I.P (VOIP) is one of them. It has gained popularity in recent times and is being widely used .Like every other system in the field of telecommunications; VOIP has its strengths as well as weaknesses. Like every other internet utility, it has its own vulnerabilities and security concerns. This paper looks into the vulnerabilities and risks affiliated with it, further touching on the features being provided by it along with its working principles in brief. The paper also looks into the role of Voice over I.P Security Alliance and its efforts to meeting the demands in terms of narrowing down the vulnerabilities that exist in various forms. Keywords: VoIP, Open standard, Vulnerability, Denial of Service. ... VOIP is established on the concept of open standards to maximum its use and accessibility (Ellis, Pursell & Rahman,pg 250, 2003). Interoperability is another feature that is making inroads across the platform all over. Having mentioned the features that are being provided by VOIP, a serious concern is being raised about its security aspect. Many a times it is being tagged as vulnerable in terms of security aspects. For this purpose efforts are needed to be in place which will insure the safety of all parameters involved in this. This is possible through study of all those areas which have loop holes in them and further working on those areas will make this a safe source of communication for customers to use. VOIP is a generic term for number of applications intended for establishing connection (Persky 2007); it could be the chat client establishment, the phone call conversation, the SMS service establishment. VOIP makes use of number of protocols that contain both the open protocols and proprietary protocols. Through the use of single broadband line, VOIP enables sending voice signals, data that includes textual format and video format information. The vulnerabilities are not just limited to its usage and application, rather operating systems, and protocols used (McGann & Sicker 2005). Types of calls possible with VOIP: Unicast calls: This kind of calling conversation involves the minimum number of parties, one at each end. It is the SIP or H.323 based call. Mostly the traffic and conversation is not encrypted and hence unsafe. Multi cast calls (limited number of callers): This includes more than two users involved in a conversation at one time. Usually a conference call where the first two establish a

What Makes Subcultures Deviant Cultural Studies Essay

What Makes Subcultures Deviant Cultural Studies Essay This paper will look to answer the question What are subcultures and what makes them deviant? It will then go on to examine and explore how subcultures became apparent and give descriptions of two different subcultures within society (specifically Punk and Rave). To conclude there will be a brief discussion regarding the specific subcultures, their members and the culture they belong to. In order to assess these subcultures it is first only right to define what a subculture is. The definition given by Dictionary of Sociology, Abercrombie (et al) states a subculture is A system of values, attitudes, modes of behaviour and lifestyles of a social group within a largerà ¢Ã¢â€š ¬Ã‚ ¦society or organisationà ¢Ã¢â€š ¬Ã‚ ¦. Most commonly applied to deviant or youth cultures that develop a culture opposed to the dominant culture. Hall et al (1976) started to examine why and how young members of society felt the need to form groups.   Youth is a relatively new term for Britain, as it only really came into existence after the Second World War. Children were no longer sent straight out to work and the emphasis moved more from work to play and growing up with ease, Youth appeared as an emergent category in post-war Britain, one of the most striking and visible manifestations of social change in the period (Hall et al 1976,). Prior to World War 2 there was always a strong ideology, a way of life to which everyone conformed. They held similar values and common goals. The emergence of subcultures challenged this. The majority of subcultures can usually be defined by specific music, with the exception of few, such as football hooliganism. The subcultures explored below can predominantly be distinguished by their music. It would be fair to assume that both the subcultures explored will have had some impact on todays university students. Either their own lives or the lives of their parents surely have been influenced by one of these subcultures. Punks In order to grasp what the punk subculture consists of it is imperative to understand where punk came from and the history surrounding it, as well as how its followers dressed, their ideals, music tastes and attitudes. There are different types of punk examples being Anarocho punk and Oi! Punk. The Punk philosophy addressed many issues including individualism, anti-authoritarianism, political anarchism, and free thought amongst others. Punk was embraced by individuals usually ranging in age from the late teen years to mid or late twenties. Punks can be perceived as members of a deviant subculture due to many factors, for example their musical tastes, dress sense and political views to name but a few. Each of these issues are to be raised in their own right, below. Within the United Kingdom (UK) the punk scene emerged in the late 1970s. As punk was somewhat of an underground movement it is impossible to state when it arrived in the UK. Cahill (1988) states that most would agree that it was sometime in 1975, Britain was suffering from a recession at the time, and in times of extreme hardship, people look for an outlet to their anger Punk gave way for young people to make their frustrations known. They Angela-Marie Gibson had just gone through times of economic decline, so un-employment was rife; add to this the normal feelings that people of this age experience, punk seemed the answer. Marsh (1977) termed Punk dole queue rock. Punk saw bands such as the Clash, The Sex Pistols and The Ramones emerging into British society. Music of this kind was often very anti or intolerant in its lyrics for example regarding parents or notions of love. Then there are other types of music to consider such as the Jam and Sham 69. The Jam are not immediately thought of as an Oi! band, but their lyrics contain political themes which is also applicable to many bands of the genre. The members of the typical punk subculture made their allegiance clear in the way the dressed. A typical punk could be seen sporting light jeans, leather jackets, Doc Martins, ripped t-shirts and, maybe, their dyed hair (some punks associated with Neo-Nazi movements had skin heads). It could be argued that the social class of the people who made up the punk subculture were generally working class, but it has to be considered that punk also consisted of a minority of middle class students who simply enjoyed the punk look, but did not conform to all its trappings. The members of the punk sub culture in Britain are predominantly white. The word punk often goes hand in hand political views. Not all punks developed the same political standing but it should be mentioned that views such as anarchy and neo-Nazism are attached to the punk subculture. The National Front picked up such punk movements as Oi! and tried to use punk to their own advantage. One must mention musical influences such as Skrewdriver, whos lead singer Ian Stewart Donaldson was instrumental in setting up Blood Honour the activist movement widely linked with the National Front. Punks could be seen as quite confused individuals as they wore clothing depicting the Union Jack, yet they sang along with The Sex Pistols and their lyrics of anarchy in the British society it was an alien essence, a foreign body which implicitly threatened mainstream British culture from within and as such it resonated with punks adopted values anarchy, surrender and decline' (Hebdige, 1979, p64) Rave The rave subculture seems to be different to punk in the fact that its follows do not seem to be constrained by social class or political view points. Rave sprang to life and made its way from Ibiza to Britain in the late 1980s and early 1990s.. It is termed by the Guardian newspaper as The fight for the right to party. Initially no one from this subculture was against any figures of authority; they basically wanted to experience a good time with their peers in an environment that had never been experienced before. This did however bring with it violence between the Police and the ravers Collin (1997) is quoted as saying rave is the most spectacular and enduring British youth movement of the twentieth century. The origins of rave can be traced back to the United States of America and the gay clubs in Chicago in the form of House music. Firstly it is imperative to ascertain what it is we are examining. Initially this paper will look at the clothes, attitudes and beliefs of the members of the rave subculture as well as the history that surrounds it. This specific subculture is closely connected with illegal drug taking and (initially) illegal venues where young people could join together to dance, party and take drugs. The countries licensing laws at this time where such that traditional nightclubs closed at 1 or 2 am. The members of the rave community wanted to party on into the night, hence the venues that hosted these events being illegal. It could be argued that the term rave was first seen in Britain in the 1950s and was seen again briefly with the Mods. However, it was the illegal warehouse parties that gave rave the reputation it possessed in the early to mid 1990s. Rave appeared whilst Britain was approaching a state of great consumer spending and the short housing boom of the late 80s was underway. In Government Margaret Thatcher was striving to ensure the British public got her strong messages regarding a capitalist society. She was attempting to portray her vision of every man being responsible for himself, On the 23rd September 1987 she was famously quoted as saying there is no such thing as society www.margaretthatcher.org. The followers of rave could be spotted in their unique clothing attire. This mainly consisted of layered clothing (which could easily be removed once they get hot), young childrens dummies, glo-sticks, whistles and smiley faced t-shirts. The males can be seen sporting tracksuits or baggy jeans whilst the females took to wearing bikinis and short neon coloured dresses. They often related everyday things to drug abuse and depicted this on their clothing. Slogans such as Can I have an E please Bob? were printed on t-shirts. They showed Bob Holness (famous for his long reign as host of blockbuster)  holding an ecstasy tablet. It is argued that at most, if not all gatherings that this subculture attended illegal drugs would be rife predominantly ecstasy, amphetamine, cocaine or LSD. In 1994 the Criminal Justice and Public Order Act was passed. This Act was influenced directly by the events at Castlemorton, where an estimated 40,000 revellers spent a week partying at an event held at the common. Castlemorton was the final nail in the coffin of the unlicensed event (South, 1999) The Act specifically defines music to include sounds wholly or predominantly characterised by the emission of a succession of repetitive beats. This gave greater powers to the Police to act upon raves. The most publicised changes in the Act are Sections 34-39, 54-59 and 60. These changes gave the Police the power to stop an outside gathering of more than 100 people. There was highly publicised conflict in the late 1980s between Police and members of the rave subculture. This, coupled with the knowledge that ravers embraced illegal substances would lead many to think that the followers of rave have little or no respect for the police or the law. Over 60,000 youths marched against the Criminal Justice Bill changes. They were all not from the rave subculture, but they all had the common belief that the changes were not just. The views of the rave sub culture may be seen as polar opposites to that of punk. Followers of rave put emphasis on peace, love, openess, unity and respect for each other. This is argued to be down to the effects of the drugs the ravers participate in. The rave subculture has moved on vastly since the early 1990s. The rave subculture now takes place in most towns and cities every weekend in legitimate venues that adhere to licencing laws. It is now called club culture and is part of everyday life for many. The members may have adapted their clothing to more mainstream atire. It could also be said that it is the rave subculture that has normalised drug use once again for the youth of Britian. It has certianly brought illegal drugs to the forefront. Faces such as that of Leah Betts will be engrained on the minds of many British citizens, predominantly those is their 30s. To quote Cohen (1972) deviance is created by societyà ¢Ã¢â€š ¬Ã‚ ¦ social groups create deviance by making the rules whose infraction constitutes deviance and by applying those rules to particular persons and labelling them as outsiders. So, if a person does not share the same morals and belief systems as the majority that then makes them deviant, therefore they have no option but to seek solace in the arms of a subculture. Looking at these subcultures I conclude that it could be argued they were influenced by the rising number of family breakdowns. Could it be that the youth of these eras were looking for a sense of belonging, and the rave and punk subculture gave them what they craved? The leader of the country at the time (Margaret Thatcher) was thought to be trying to in still into the British people that society was not important maybe subcultures fulfilled its followers with a sense of belonging and security? If the people were being lead to believe that wider society was not as important as it had been then can a subculture really exist, as there is no common goal or majority rule. It also must be pointed out that with the vast amount of media coverage both of these subcultures received from the newspapers and television it could also be argued that they were the norm they had so much coverage that to attach a deviant label to them is wrong. Maybe due to the fact that we have only seen these deviations from the norm over a relatively short period of time (Post World War 2) it is still inconceivable to some members of society that freedom to express ourselves should be embraced, not shunned?

Sex vs. Solitude Essay -- The Woman in the Dunes, Onehundred Year

Solitude can exist in many ways and can be present in any form in human beings. Each person is eventually alone deep inside themselves, which is why communication and connections are essential in life. In the novel One Hundred Years of Solitude by Gabriel Garcia Marquez and Kobo Abe's The Woman in the Dunes, solitude is one of the main dilemmas that the main characters in the novels encounter. In the novels, the main characters are perpetually looking for a way to defeat their loneliness in the world and in many cases try to find it through sexual intercourse. The patriarch Jose Arcadio Buendia, in One Hundred Years of Solitude, is the founder of Macondo. The location of Mocondo is significant as it sits on an isolated place which gives the sense of the Buendia family being surrounded by solitude. It also seems as if solitude is an inherited trait of the Buendia family leading to a pattern of incest, which was started by Jose Arcadio Buendia and his wife, who is also his first cousin, Ursula Iguaran. Sex is probably used in the novel as a way to somehow bond the family together. Sex can be used as a tool to make connections to one another and can create body language which can also be a way of communicating. We see this especially in the second generation of the family, when Colonel Aureliano Buendia has sex during the wars with seventeen different women (which he shows no sign of predilection towards). You can also deduce that he went on a journey to free himself from solitude and overall was unsuccessful as it was shown when he m ade an attempt to get with the adolescent mulatto girl enslaved by her grandmother. This shows an effort by one of the Buendia men to try to have a loving relationship with another chara... ...There was no particular need to hurry about escaping." (239). Realizing his situation, he becomes one with the dunes and is able to live a purposeful life with the woman he once opposed living with. Without any type of sexual relationship, none of the characters in the novels One Hundred Years of Solitude by Gabriel Garcia Marquez and Kobo Abe's The Woman in the Dunes would have been explored thoroughly. Sex usually exposes a hidden hope or apprehension, desire and lust for something. In this case the characters of the novels lust, desire for identity and companionship, and is something they strive to acquire. In order to attain this, they attempt to use sex as a tool to triumph over solitude and gain communication and connection to reach one another. This is why sex is essential in providing two crucial things that are necessary in life to avoid solitude.

Qualitative Analysis

Qualitative Analysis 1. Abstract Qualitative Analysis helps to analysis the ionic compounds ( cations and anions) which are presented in a salt (solid and in a solution). The experimental procedures show the identity of the substance but not the amount of the present agents. 2. Introduction The construction of ionic salt is based on a certain cation and a certain anion. To get to know the two different agents of the salt, the anions and cations has to be separated.For the separation the ionic salt has to be destroyed by chemical reaction to get the single elements and compounds. A physical reaction can only change the conditions of the salt ( solid or fluid) but not the structure of the educt. Every element and compound has characteristic reactions where the identity can be figured out by analyzing the out coming educt by its color, its odor, its precipitation and its solubility. The following experiment is separated in two parts.In the first part of the experiment, it has to be show n the different characteristic reaction with the cations (Na+, K+,NH4+,Mg2+,Cu2+,Ag+,Ba2+,Sr2+) and the anions ( Cl-, Br-, CO32-, SO42-, F-). In the following part there was an unknown ionic salt to analyze which is built out of one cation and one anion from above. 3. Materials and Methods 1.

Discussion The cation Na+ was easy to figure out because of its unmistakable color of the flame by holding into the Bunsen burner flame. It was more difficult to get to know the anion. The experiment with silvernitrat could be leading to a wrong conclusion. In the table [1] is written that there is no reaction ( precipitation) in the experiment with AgNO3 and CO32-.It could be that the test tube wasn’t clean and there was still some undesirable rest of another element or compound. Even a single grain of I- could cause a precipitation. Another problem to find the right anion was that the amount of our unknown salt was too low in our testing solution with acid sulfur. So there was no visual reaction with our unknown solution. But the second time with a higher amount of unknown salt in our testing solution there was a CO2 development. To be sure that this experiment is positive the experiment was repeated with HCl. There was the CO2 development good visible. Thus in the end the anion CO32- was proved. 6.Conclusion To do the right analyses it is very important not to trust a single experiment. Controls are very important to get the right elements and compounds. Also it’s very important to check wheather the equipment is clean. Any single rest of an undesired substance can imitate the result. But these are good experiments to get to known unknown element s and compounds of an ionic salt. 7.

Discussion The cation Na+ was easy to figure out because of its unmistakable color of the flame by holding into the Bunsen burner flame. It was more difficult to get to know the anion. The experiment with silvernitrat could be leading to a wrong conclusion. In the table [1] is written that there is no reaction ( precipitation) in the experiment with AgNO3 and CO32-.It could be that the test tube wasn’t clean and there was still some undesirable rest of another element or compound. Even a single grain of I- could cause a precipitation. Another problem to find the right anion was that the amount of our unknown salt was too low in our testing solution with acid sulfur. So there was no visual reaction with our unknown solution. But the second time with a higher amount of unknown salt in our testing solution there was a CO2 development. To be sure that this experiment is positive the experiment was repeated with HCl. There was the CO2 development good visible. Thus in the end the anion CO32- was proved. 6.Conclusion To do the right analyses it is very important not to trust a single experiment. Controls are very important to get the right elements and compounds. Also it’s very important to check wheather the equipment is clean. Any single rest of an undesired substance can imitate the result. But these are good experiments to get to known unknown element s and compounds of an ionic salt. 7.
