An Analysis of the Signs and Symbols Used in Patek...

MM 204 - MARKETING COMMUNICATIONS An analysis of the signs and symbols used in Patek Philippe Geneves Begin your own tradition advert. - MARCH 2007 - INITIAL INTEPRETATION This advert shows a dad helping his son with his homework. This is a common right of passage for many families. The advert stresses conventional family values and the importance of the father-son relationship. The watch is presented as a precious family heirloom which dads should buy to pass on through the generations. Thus the watch has a purpose beyond its function, a purpose of tradition. SIGNS SEMIOTICS Utilitarian signs There are limited signs relating to the practical aspects of owning a Patek Philippe Geneve watch. The functional aspect of the†¦show more content†¦With the exception of the watch, there are no rounded lines suggesting femininity (Blythe 2006), there are however many sharp, angular lines both in the creases of the book, the clothes and the background which suggest masculinity (Blythe 2006). Body Position It is also noticeable that the man is at a slanted angle to the boy. The man is in an upward left to right angle, which denotes upward movement (Blythe 2006) i.e. the progression, from a man to the boy (and thus the inheritance of the watch). Context of the watch The positioning and eye-focus of the father and son (both looking down at what is perceived as the sons homework) suggests that father is helping his son with the homework. In a connotative context this suggests the acquisition from father to son of positive cultural values. This places the passing of the watch from father to son in a context as important as education. SEMANTICS Legacy and self-actualisation. The sentence Begin your own tradition taps into the importance of legacy. A popular school of thought in post-modern culture is the desire of men to create a legacy in the latter part of their life (Powell 2005). It would probably be easier though to classify legacy as part of Maslows (1943) self-actualisation bracket. Regardless, there is a clear attempt in the advert to appeal to men who want to create their own legacy. Separatism Begin your own tradition in note (6) implies separatism from society. This

Maslow s Theory Of Motivation - 1103 Words

†¢ NEED THEORIES Need theories describes motivation as â€Å"the willingness to exert high levels of effort toward organisational goals, conditioned by the effort’s ability to satisfy some individual need† In this context, a need is an internal state that cause a specific result to look pleasant. An individual’s drives are stimulated when tension is created due to an unsatisfied need. A search behaviour is generated to locate specific goals, if this is obtained, the need will be satisfied and the tension will be reduced. Needs could be said to physiological or psychological deficiencies that stimulate behaviour. This differ with time and place, as environmental factors can influence it and make strong or weak. Maslow – deficiency needs vs†¦show more content†¦If employers fail to do this, this could lead to a theoretically increase in the frustration of employees and performance levels will reduce, job satisfaction level could also reduce and withdrawal from the organisation could increase. For example, relating job insecurity to this theory, if an employee feels any threat of layoff, this can hinder the individual from their higher growth needs. This could lead them to push harder in acquiring job security but neglecting to fulfil their other needs. If at the end, job security isn’t attained, an employee might try to fulfil their needs somewhere else or burn out. Alderfer’s ERG model The theory of Clayton P. Alderfer’s ERG from 1969 compresses Maslow’s five human needs in three division: Existence Needs: this involves all material and physiological aspiration. (e.g house, food, water, air, safety, physical affection and love). This is similar to Maslow’s first two levels. Relatedness Needs: to be accepted, identified and feel safe with a group and family. This correlate with the third and fourth levels of Maslow’s hierarchy. Growth Needs: self-actualisation and self-esteem; this compels an individual to make ingenious and productive change to himself/herself and the surrounding. This is similar to that of Maslow’s fourth and fifth levels. Relationships between the concepts There are three relationships among the

The Topic Of Religion ( A Focus On Pastafarians ) Rough Draft

Aaron Mendoza Farmer ENGL 1301 12/01/14 On the Topic of Religion(A Focus on Pastafarians) rough draft Hello, madam, have you accepted our lord and savior, The Flying Spaghetti Monster, into your life? the man says, a colander on his head, with a vaguely pirate-esque accent. Another annoying pastalatizer arrived at your door. What do you say? Ignore him or hear him out? Is this man insane, or does he simply see you as someone to prank? Is this a game? Well, you re answer could be any of the above. In 2005, in a letter to a governor, a man mentioned a hypothetical Flying Spaghetti Monster, as a way to dispute creationism. This has been adopted by teenagers, pranksters, atheists, and true-believers alike. The church’s website, venganza.org states â€Å"Some claim that the church is purely a thought experiment, satire, illustrating that Intelligent Design is not science, but rather a pseudoscience manufactured by Christians to push Creationism into public schools. These people are mistaken. The Church of FSM is real, t otally legit, and backed by hard science. Anything that comes across as humor or satire is purely coincidental.† It of course raises the question, when is a religion legitimate? It s a matter of semantics, really. The real question is not if these are legitimate, but what do these satirical religions say about our society?. What do these do for society? They provide a view into the madness that religion itself entails, allowing us to discern the boundaries that

Medias Influence on Body Image Essay example - 1550 Words

1.0 Introduction The media have been criticized for portraying the thin women as â€Å"ideal† .This research plans to look at the effects of media on the body image of women. This cumulates the findings of empirical studies that observe the effects of media on body image. This study will also look at the different social comparison theories that relate media and body image. It will also investigate the different sources of media that have an impact on the body image of women. It also scopes to find out which sources have a greater consequence than the others. Furthermore it also researches about how the women could be prevented from comparing their body image from that of the models and actresses portrayed in the media. 2.0 Literature†¦show more content†¦Whereas in the recent years slim women are more valued according to Jennifer A cited in O’dea. body image discourages one from participating in physical activities. Physical activities could be participating in sports where on e has a feeling of being â€Å"too fat† or feeling that one has to achieve a certain look before they can participate (Paxton , 2002, P. 4). 2.1 Theory Researchers have utilized various theoretical findings for examining the relationship between media and body image (Holmstrom, 2004 ). Here is the review of the theories that has been used by the researchers in the area. The most common of these theories is Festinger’s social comparison theory (1954, P. 120) where he argues that people assess themselves through comparison with others and more likely to compare themselves to those who are similar to them and who are attractive. This theory is aimed to encourage one to improve if she finds herself lacking those qualities. On the other side researchers who use social comparison theory claim such comparisons could have probable negative consequences. For example Bandura’s social cognitive theory (1994, P. 80) emphasizes that people study the behaviors of attractive others. This theory suggests that young women find slim models attractive and thus try to follow their routine through dieting which ultimately leads them to eating disorders. The last theory is the Gerbner’s cultivation theory which suggests that the more a person isShow MoreRelated The Medias Influence on Body Image Essay4394 Words   |  18 Pagesby which females are taught from childhood to judge the worth of their own bodies (Stephens Hill, 1994).

Analysis Of Frank And Alice s Views On Politics - 919 Words

Malik presented Frank and Alice who consider themselves to be Republican/ conservative. Frank is a registered republican who wishes other knew that republicans are a group that have been stereotyped to be a bunch of racist ignorant people. Feels pretty much unsafe to speak about politics in public because of the way he may be judged. Media often makes the portrayal of certain political parties which influence and make others bias instead of actually doing their research and choosing which party they connect with the most is a change he would like to see. Alice identifies as a conservative that wishes others would know that not all republicans fit the bias of the same portrayal Frank expresses. Unlike Frank, Alice does speak about politics but often gets into heated arguments because of her beliefs and political views. A change to see is to have conservatism taken more seriously instead of making it a joke in the media. Biased or not, voters should take to the books learn our history and be more aware of the candidates who wish to run our country. Josà ©, interviewed Cesar and Mikel both consider themselves Republican. Some of the things they wish others would know about republicans is that family and religions are important and most of them educate themselves on political issues.

Discovering Yourself free essay sample

DISCOVERING YOURSELF This topic is very interesting with the Discovery wheel, learning styles, and balancing learning styles. My favorite assignment was the discovery wheel, this exercise shows me that I need to balance the skills that I have and some real weaknesses that I did not know that I had. Discovery is a way to find your TRUE strengths and weaknesses and how balance them. Discovery, commitment, and Mastery should be in every student vocabulary and should be something worked on daily. In my opinion, discovering yourself topic is perfect to be chapter 1 because you can start discovering yourself and improving your skills through out the course as well as your time as a student so that when you graduate and are working in your career chose you could be a more balanced and well-rounded person. The chapter showed me that I could change my learning style or habits to promote success by being able to learn from any instructor.

Staying focus on my goals ahead, and start working on small changes first and then looking at the big picture. I will practice the skills that I have learned in this chapter daily to my educational career, workplace, and social settings to grow as a person. In school, I will use a full range of learning Modes to excel in my classes and develop variety of strategies to be able to learn from a wide range of teaching styles. In my workplace, I can use what I learned to look at the bigger picture through being more creative and having a willingness to take risk. I also discovered a need to focus on my time-management and getting more organized. Time Management was something I thought I only needed a little bit of work on, but I see through the discovery wheel I needed alto of focus and change on this skill. Discovering yourself chapter is a good revelation and was a great way for me to see my weaknesses on a larger scale. NOTES Note taking is very important in being a better learner, enhancing your memory and helping you pass test. Television note taking was a good exercise, because it shows you that you can try different techniques and see which one works better for you and with is you can transfer that technique into school or work. Note taking is more than rewriting what the instructor or fascinator is saying, but writing it down in a way you can understand it. You want to observe a statement by an instructor or facilitator, record your observation of that event â€Å"take notes†, and finally you want to review the notes that you took. All points are valid and are not successfully without doing them all. Through out this chapter I gained a better since of note taking and taking notes more effectively. My original style was to rewrite what the instructor or fascinator is saying but I rarely know what they were talking about and that caused me to take more time and research what the topic was and read a lot more on topics that were not relevant to the class. The formats explained in this chapter are effective with different forms of lecture. If an instructor is speaking fast try to focus your attention on key points, exchange notes with a classmate, leave space in your notes to fill in information you might have missed during the lecture, if all else fails speak to your instructors to see if he or she can slow down or speak to him or her after class. If you are note taking while reading you can paraphrase key points, outline the table of contents, and try taking research notes that can help you understand the reading better. I can take the techniques that I have learned in this chapter into the workplace as well as the classroom. I take notes in conferences and seminars and these tools can help me process what I am learning. Many instructors speak faster than I can write and sometimes I find myself either not taking notes and trying to remember what they said, or trying to write everything they said and missing the point all together. I will use the tools in this chapter and will work with others to make sure that I can get the complete information from the lecture. The other points in the chapter I will put into effect while in class and reading assignment trying to map my chapters with main points and making the charts flow from general concepts to specific ideas. Observing, report, and review is an all around concept that can be used in class and work to help me in the ability to remember what the chapter or lecture was about and to be successful in test taking. TIME This was a excellent topic with the Time Plan Process, Getting real with your Goals, STOP PROCRASTINATION NOW which was my favorite assignment in the chapter, 7-day antiprocrastination plan, long term planners, and Master Calendar. This chapter covers discovering how you currently use your time through using planner’s charts and calendars. It also covered how setting goals that will make a difference in the quality of your life and what to do today, this week, and this month and making sure that you reach your goals using techniques to simplify your goals to make them more attainably and reasonable. Last but definitely not least, now to eliminate procrastination through all the techniques above if you focus, follow, and try something new you can definably get pass being a procrastinator. I gained the knowledge of how to effectively schedule, plan, and prioritize my workload al well as keeping a master calendar that I stick too. This is not only helping me through out on time as a student, but in the workplace too. My work schedule is very busy and seems to be always full but when I used the tools that I read about in this chapter I noticed that I could delegate some of my responsibility to others and prioritize other task to use make the best use of my time. This topic was the least amount of points on my discovery wheel and I made sure that I read this chapter carefully, took notes, and implemented the techniques to gain understanding and the ability to have better time management. I know that I cannot stop being a procrastinator over night but if I stick with the techniques shown, I can have better time management. I have started using two master calendars one for work since we have deadlines every month that need to be completed on a timely basis. We also have events that are planned months in advance so this can help me to not overwork myself through out the month and to visually see what is going on for the month with out guessing. I have also should people that I work with this idea and others are using this technique also. The other master calendar is for school it has my class schedule, KGA due dates, and exam date on it. I look at the assignment that is due and add study and prep time to my master calendar because I can not forget my focus is my degree everything else comes secondary. I also have started using my student planner that came with my class book more effectively by making sure that I put down everything that is going on from work and school into it not just class activities. This helps me when I am planning work events I can block out time that I know I will not be available. The sue of the planners, calendars, goals setting, and time planning processes shown in this chapter this will make me a stronger student and person.

A physical change will not change the composition of a substance. When adding water to a salt, the ions of table salt are hydrated with water molecules which reduced the strong electrostatic forces of the ions. To return salt to the original state, simply remove the hydrated water molecules by boiling the table salt. Conclusions: In a chemical change one or more new substances are formed. The new substance has its own unique identity which is different from the original. It has properties that are different than those of the starting material; in addition, the original materials is not able to be reproduced by physical means.
