Cliches and My College Writing Experience - Essay Example The course allowed me to learn how to well articulate and integrate my opinions into essay assignments in the correct academic writing format. Professionally, the course has assisted me to become better at writing emails to my professors, tutors, and friends. From learning the course, I gained the ability to formulate well written and cohesive emails. I have experienced few difficulties as I strove towards taking a more scholarly approach in writing. The first difficulty I got to encounter was getting to learn MLA format by looking in the textbook. I had no prior experience in this format and getting to learn it by myself proved a challenge. The textbook provided great assistance but it became limited in showing how the MLA format gets learnt practically. Another difficulty I encountered was with my spelling. Scholarly writing requires correct spelling and thus it proved a challenge on the first instance. The more I got to get through the WRIT 111 course, the more I got to improve on my spelling as I received help from the writing center. The assistance I received from the writing center greatly influenced my improvement in spelling. I believe I have mastered most if not all of the learning outcomes of the WRIT 111 course.

No Topic Yet - Research Paper Example Bowerman, Connell and Orris (2004) explains that to effectively develop a marketing plan, there is a need of the marketers of an organization to collect data that is able to depict the preferences of customers regarding the products of the company. It is this type of information that Nokia used to correct its weaknesses in the marketing strategy, Nokia began collecting data that highlighted the kind of mobile communication gadgets that consumers preferred. This paper gives a detailed analysis of how Nokia used this information to transform its business operations. Nokia Corporation is a telecommunications company that was formed in the year 1967, mainly because of a merger of three companies based in Finland. After entering the telecommunications business environment, Nokia was able to quickly develop itself as an innovative company that produced highly technological products, especially mobile handsets. In the 1980s, Nokia was able to develop a long term expansion strategy by acquiring French, Finnish as well as German electronic business organizations. These acquisitions were able to strengthen the position of the company in the field of consumer and telecommunication electronics. Approximately 80% of the revenue earned by the company emanates from its mobile business operations (Matsuo, 2013). This is despite the huge competition, and the current downward trend that is experienced in the mobile telephone market. Millar, Millar and Choi (2010) further explains that Nokia controls about one third of the mobile market all over the world. However, during the later years of 2000, the dominance of Nokia in the mobile phone industry began to diminish. This is because of the introduction of smart phone products from companies such as Apples, Samsung and Google was able to take the company’s market share. For instance, the Android operating system of Google, and the iPhone of Apples proved

Bottled Water Essay Example for Free

Bottled Water Essay Bottled water is one of the easiest ways for getting good water. Bottled water is every where in offices, airplanes, stores, homes and restaurants across the country. People think that bottled water is the best option for their health instead of drinking tap water because they say tap water is not completely pure. What they dont know is that tap water is the same as drinking bottled water because industries like Nestle gives us tap water in plastic bottles. Plastic bottles contain many chemicals that damage our system by giving us different diseases. This increases the risk of people getting diseases while years pass. People dont research enough about how is bottled water is made and how they are just taking away our money in this type of products. Before watching the video about bottled water, I realized how bottled water affects our system like a person and how it affects our environment. After watching the video I really didnt drank bottled water because I am an ecologic person. I have always recycled bottles and in my old school I promoted ways to recycle bottles, and why to recycle. I realized all the pollution is going on in the earth and I like to keep it clean. Even if I am the only person who is recycling one person makes some how some difference for the planet to breath at least a little bit. It makes me sad how people dont care about our planet knowing all the struggles and the lack of resources we now have. I have my personal plastic bottled to refill to drink water. This is some how good for the planet because we can use one water bottled and drink tap water and recycle. If industries like Nestle are giving us tap water in their fancy plastic bottles to make us believe that they are giving us pure water, why not drink tap water if it is the same. In reality, bottled water is just water. Bottle water means garbage, plastic bottles just makes more garbage in the planet and not all of them are recycled as the recycled industries say they are. Most of them end in the Pacific Ocean, rivers, lakes, etc. Plastic bottles besides killing us with their chemicals they also kill animals. This plastic bottles end up in lakes and in natural environments. Fish, birds, and other animals end up eating some how plastic because it is in their environment, this increases the percentage of animals dying in our natural environment; causing endangered animals. It makes me sad how people knowing how plastic bottles or even in my Earth Science class know how tap water is the same as bottled water are the same and they keep buying them. Why not buy your own plastic water and drink tap water if it is going to be the same kind of product and this way we can recycle by using the same water bottle many times, and drinking the same product that industries like Nestle are providing us in bottled water. I hope that with this critical analysis some of my classmates realize how bottled water is bad for their health and how bottled water damage not only us but also our environment. There are many things going on besides bottled water polluting our environment and damage other living animals. Lets no be selfish and take in consideration all of this information. http://www.epa.gov/ogwdw/faq/pdfs/fs_healthseries_bottlewater.pdf http://www.rd.com/health/rethink-what-you-drink/ http://www.chem.duke.edu/~jds/cruise_chem/water/wattap.html http://topdocumentaryfilms.com/tapped/

The Importance of Voice in Writing :: Essays on Writing

For my first paper I'll talk about voice, and how it affects the conversations that we have with other people, and how we perceive certain voices to sound in stories, and other works that we read. I think that in general voice is a type of mystery, and that it is one of those things that we really can't understand. When looking at a piece of writing I think that a clear and concise voice is one of the things that makes a piece work. This is my own feeling, and it might not agree with others, but when I'm reading a story, and it is full of good stuff like conversation, and heart felt feelings, I feel that the author is able to tell me what he/she is trying to say, I think that it has a better impact on the reader compared to the writing that goes on about nothing, and seems to only have one monotone voice. I think that one of the best ways to create a clear voice while writing is to pretend that you are talking to a friend, and having a conversation about what happened in one of your most hated classes. For me this is an easy way to create a voice that isn't to dull, and with any luck will hold the attention of the reader all the way to the end of my work. This type of voice isn't all that hard to create, but using it at the right time might be a little tricky. According to what Morgan said in class the last time we met, voice isn't used all that often in technical writing. This would explain why some of the texts that we are forced to read are so boring. The authors of these books aren't looking to entertain, they are looking to educate, and get a point across to the reader. This is true foe the most part, but wouldn't it be nice if we could pick up a text, or a manual for a new computer, and understand what is being said? I think that in the near future many of the books, and manuals that will be coming out will have a new voice of their own. I think that in general people find it easier to understand what is being said if the writing or instructions that they are reading seem to make sense, and don't sound like the author is trying to make them feel like an idiot.

Driving Teachers Crazy Essay

Teaching is not just earning a buck, it’s a snap. At the beginning of a new school year with high school sophomores, Mr. Finn is working at his desk wondering what the first period is going to be like. While waiting for the bell to ring, most students stand in clusters talking quietly but a few the knock- upstairs are rather loud and boisterous around the room causing a commotion with every group they pass. Not wanting to be overly negative on the first day, Mr. Finn says nothing. By the time the bell rings most of the class has become loud and boisterous. Although, teaching is a snap. Some students make it rather difficulty. When he realizes that his class is going to be immature, he will need to learn self-discipline. He remembers the classroom management suggestion he learned in college. â€Å"Don’t simile until Christmas and be tough on the first day†. Therefore, he commands everyone to sit and get the class started. From the time of role call to the time Mr. Finn is passing out textbooks, and then thought the introductory lesson, several students are loud and sometimes obnoxious, others to the other side of the room are murmuring, swearing and don’t forget the corners someone is snoring. He tells the students to be quieter, but they don’t listen. By the end of the first period he wonders whether his going into teaching might have been a mistake. He wanted to teach and help young learn, but certainly lost he thinks, when you spend your whole day disciplining students rather than teaching them. As routine as it may sound, this is the experience that I go through everyday. Having twenty students a day that are as loud as action is never pleasant. By the time I get home I head to the fridge to get chocolate ice cream not just because I need it, but also because want it. Noise distracts other slow learners as well as teachers. It maybe that this student needs to be noticed and recognized. I have a friend who always shouts to be noticed, being loud seem to enhance her personality, and sometimes to appear tough. It is so irritating when you are reading and  someone shouts loudly keeping you off track. This student need to encouraged repeatedly, she requires redirection and always told to demonstrate mature behavior. Secondly, name-calling is also a common occurrence and very nefarious. It bothers me when a student calls someone a name just to be noticed or for attention. Although there are key problems that lead to this behavior there are key issues behind the scenes. One key major aspect is sexuality, a student may feel that he/she is an outcast or cannot make friends. He/she attracts attention from peers through name-calling. Some classmates are also amused by this behavior – as long as it’s directed toward someone else. Sometimes, a student may have a need for food and drink, and may be covering this need by name-calling. A teacher has to recognize why the student is presenting this behavior in order to be of help. There are things that can be done by the student. A close relationship with someone may reduce this student’s need to call others names. Another irritating behavior is making fun of other’s weakness. People need to belong and respected no matter what their weakness, if this is taken advantage of they might be hurt or discouraged. Last year, I had a friend in my health class, he had a domestic problem and that his parents were divorced. Now that he lived with his mother who couldn’t support him in any way, he thought he could the world it all belonged to him. This friend of mine was real dumb and ill tempered, even though you greeted he thought that he was being insulted. He also had problem with English since his home language is â€Å"French† sometimes he would pronounce words with an accent for example â€Å"wit† instead of â€Å"with†, other students thought that this was weird or even fun and they always made fun of him they even nick-named him â€Å"wit†. As time went by, he suddenly stopped talking. Early in the morning he could sit by the corner and sleep. There are students like my friend who have different weaknesses, it doesn’t mean that they are different although they seem that way. A teacher can help these kids by getting a translator or after school tutoring. A teacher may all own the class to establish rules regarding this behavior. Our goal is to make † making fun of other’s weaknesses† socially unacceptable. School time dozing is another major problem in history of the classroom. In the middle of a discussion, a teacher unexpectedly stops speaking. Everyone stops speaking, nothing is heard except a faint sound from somewhere in the corner. Noise that sound like†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.snoring? Suddenly with a loud thwack! The teacher claps a book shut and the snoring culprit is jarred from his sleep, lifting his head up with blear- eyes all ashamed! You would think times have changed. Falling to sleep among today’s teenagers is a common occurrence. Why do the sleep in class? An obvious reason is lack of sleep. IT bugs me when someone is snoring and I am studying or typing. I remember last yeast in my keyboarding class a boy who sat adjacent to me. He slept and snored real loud, that the ceiling could tremble. I could hardly contrite and since this was a keyboarding class that never cared much the rule was â€Å"Do all you can but turn in work on time†. The only possible cure to school time dozing is personating time for activities as well as schoolwork. I conclusion, being a teacher can be tiresome. No matter how routine the day, still teachers get away with it. Teaching is supposed to be a snap as you lock the door, driving by the countryside sing † I t was horrible, but I managed†. Although you spend all day disciplining instead of teaching them.

Feminism in Northanger Abbey and Persuasion by Jane Austen

Feminism in Northanger Abbey From my point of view, Jane Austen should be seen as a ‘feminist’ writer. As she wrote in one of her novel Persuasion, she considers that ‘Men have had every advantage of us in telling their own story. Education has been theirs in so much higher a degree; the pen has been in their hands. I will not allow books to prove anything’ (Anne Elliot, in Jane Austen’s Persuasion). Such feminist ideas are expressed in many of her literary works. In her another novel Northanger Abbey, there are various issues discussed, which include not only marriage, social criticism and Gothic, but also feminism as well. The essay is to discuss Jane Austen and her feminist thoughts by analyzing Northanger Abbey. The analysis will cover three aspects. First of all, in her book, Jane Austen expresses the view that both genders possess equal creative and intellectual qualities, and thus women are born to be equal to men. Second, she expresses her sk epticism towards the degree of rationality and justice of the common social norms about female behavior. The third aspect is that Austen also insists that women should act for themselves in a rational way rather than merely trying to impress or to please the other sex. First, though Jane Austen’s Northanger Abbey is not completely categorized as a feminist novel, by portraying the protagonist Catherine in the way Jane Austen does, she expresses her opinion that women have been individuals withShow MoreRelatedEssay about Feminism in Jane Austen1034 Words   |  5 Pages Feminism in Jane Austen quot;I often wonder how you can find time for what you do, in addition to the care of the house; and how good Mrs. West could have written such books and collected so many hard works, with all her family cares, is still more a matter of astonishment!
