本文主要以十八支電視廣告為對象，以Bourdieu的日常生活實踐理論與AIOs、VALs生活指標結合，放入研究脈絡中，並以符號學的分析方式，來觀看大哥大廣告呈現出的消費文化品味類型、消費文化類型隱含意義、以及經過時間歷程對於大哥大消費文化類型意義流動的影響等問題。 結論發現，六種消費文化類型中， 菁英領導型佔有五則、崇尚創意型四則 、隨心所欲型四則、社交應用型三則、價格取向型一則、都會新貴型一則，儘管消費文化類型各有不同，文化中仍存在著幾個相同的主流價值，如對勝利的追求、對成功的渴望、對美好未來的期盼、對自由的嚮往、對簡單的需求等，面對這些主流價值，反映在每個消費文化類型與人生階段的脈絡上時，卻有著截然不同的廣告表現型式。菁英領導型、社交應用型追求的都是一種牽涉到以男性為主權的職場領域，在社會潛移默化的教化下，呈現出「男主外、女主內」、「男強女弱」的父權優勢價值及「追求成就」的成功價值觀；而崇尚創意型、都會新貴型，追求的卻是品味出眾的角色認同，藉由「內外兼具」、「彩色人生」的信念，建構出真正內在追求認同與歸屬的價值習性； 另外，隨心所欲型與價格取向型，即是呈現出隨心所欲的自在掌握生活，其中更體現做自己的價值觀。由此即可反映Bourdieu所言的習性，每個族群皆有其獨特的價值觀，每個價值觀皆是影響每個族群消費文化品味的要素，而活動領域也因此受習性的影響，有的族群游移於職場、有些則在家庭、有些則在社交場合等等，因此在習性與活動領域交錯下，消費文化類型的品味一覽無遺。 而大哥大在台灣發展的情形非常符合從使用價值到符號象徵價值轉向的分析，廣告分析中，從消費文化類型中歸納出以下三種社會階級：一是社會新鮮人、二是家庭主婦、三是菁英主管。社會新鮮人或家庭主婦，都希望藉由學習或模仿能成為廣告中的角色，試圖讓自己的社會身份得以向上流動 。而菁英主管型，由於已擁有令人稱羨的成就與權勢，因此，其即會產生水平身份地位的流動，希望依然能掌握權力態勢。 / Mobile Phone is advertising agency's new lover in these two years. Since the liberalization of telecommunication, mobile phone sellers import all kinds of phones in huge amount to supply customers' demand. After an year's "Supply and Demand", the market of mobile phone is under a kind of stable situation. Meanwhile, many sellers have lots of stock, and these stocks push them to promote in various ways. Certainly, many commercial advertisements come out. With all possible promotions. the importers can sell out their stock to reduce their cost pressure. It also enlarge the market scale by stimulate this market with lower and lower price. The market scale is easily enlarged by those potential consumers as we can find out.Right now, mobile phone is more than a telephone for communication and something symbolic and material. Here I will start with the major concept from the theory of Bourdieu. From its structure of theory, we could view the different classes among habits, capital, and fields. They mean different taste of consumingf, also life style. Making use of 18 commerical advertisements by semiology, I finally categorize five kinds of Consumer Behavior as follow. 1. Elite Oriented 2. Creativity Oriented 3. Whatever Oriented 4. Price Oriented 5. Social Oriented 6. New Nobility. Despite the different consumer behaviors, there is existing main stream in our culture and value like chasing victory, hunger of success, the expectation of wonderful future, the dream of freedom, and the demand of simple. Facing these main streams of value in our society, all different commericial advertisements reflect all kinds of our cultures one by one neatly.

In the process of optimizing the quality of their entire product range, Sony Ericsson Mobile Communications AB have decided to review their free fall drop test equipment with the goal of increasing the precision, repeatability, and time efficiency of their drop test applications. In regard to the free fall drop test principle a robot system with management software, named Doris Drop Test System, is developed to meet these goals.</p><p>As the amount of related work for this application is as minimal as the timeframes for this project, the development process is empirical and entrepreneurial with engineering skills as the governing line of work. Combining the competence from fields such as mechanics, electronics and product development, reaching the goals is successful enabling the identifying of two different drop methods – Impact Position and Drop Position. Increasing the repeatability from approximately 10% to 85% enables anyone at any time to perform the exact mobile phone drop test. By reaching a precision of up to 100%, performing free fall drop tests aiming for testing specific mobile phone parts, optimizes the development process by faster detection of mechanical weaknesses. Achieving these results in parallel with increasing the throughput by shortening the testing time, has proven the success of the Doris Drop Test System.</p><p> </p>

This thesis aims to increase the knowledge on people with symptoms attributed to electromagnetic fields (EMF) by investigating the effects of EMF exposure and by additional description of the heterogeneous group of people reporting EMF-related symptoms. The effect of mobile phone (MP)-like radio frequency (RF) fields on symptoms, autonomic nervous system (ANS) parameters, short-term memory, and reaction time in persons with MP-related symptoms (MP participants) was investigated in a provocation study. A second provocation study investigated the effect of similar exposure on serum concentration of biomarkers in persons with atopic dermatitis. No effect of exposure was detected in either study. MP participants displayed changes in heart rate variability (HRV) during cognitive tests, but not during rest. This contrasts with earlier findings, participants with symptoms attributed to EMF sources in general (EHS participants) displayed an elevated sympathetic nervous system activity both during cognitive tests and during rest. Proposed differences between subgroups of persons with EMF-related symptoms with respect to symptoms, personality traits and stress were investigated in a questionnaire study. MP participants reported primarily symptoms from the head; EHS participants reported symptoms from many organ systems. Furthermore, EHS participants reported higher levels of anxiety, depression, stress, and exhaustion when compared with a reference group. MP participants reported higher levels of anxiety and exhaustion only. In a pilot study, 24-hour and short-term HRV were investigated in EHS participants, to examine whether the previously observed sympathovagal imbalance would still be present. There was a tendency toward increased parasympathetic activity compared with earlier recordings, and a reduction of symptoms. Twenty-four hour and short-term recordings were fairly similar for each participant; however, there were large between-subject differences. The results do not support the hypothesis of effects of MP-like RF exposure on symptoms, ANS activity, CFFT, cognitive function, or biomarkers. However, they do support the hypothesis that persons with different symptom attribution (MP and EHS) may differ also in ANS activity and psychological aspects.

The aim of this study was to analyse ninth graders self reported screen based activities, sedentary time and musculoskeletal symptoms and pain intensity. The other aim was to examine changes regarding musculoskeletal pain and inactivity between ninth graders from a cross sectional study in year 2004. To meet this aim, following questions were designed: How is the relationship between screen based activities, inactivity, musculoskeletal symptoms, pain intensity and differences between girls and boys? How have musculoskeletal symptoms and screen time changed since year 2004? Method: The method used for this study was a quantitative method. The research was carried out using a questionnaire that was answered by pupils from 11 schools from all over Sweden. The response rate was 85 % (n=465). The level of statistical significance was set at p&lt;0.05. Results: Mobile phones were used three times more by girls and TV Games were used seven times more by the boys.  Tablet computers were used more randomly by 80% of the youths. Headache occurred 58% and neck pain occurred 68 % with those who used mobile phone &gt;3 and &gt;5 hours per day. Backache occurred with 19% of those watching TV &gt; 3 hrs. Headache ongoing for more than a month occurred twice as much among the girls and was perceived as having a severe effect on everyday life. Boys reported neck ache and shoulder ache longer than a month somewhat to a greater extent. Nearly twice as many of the boys considered themselves being more physical active and resemble the most active person. Total sedentary time was not significant but a third of the youths reported that sitting time for 7-9 hrs during weekdays and 4-6 hrs during weekends. Differences between 2004 and 2013 showed that occurrence of ache and continuous back pain decreased whilst headache and continuous back pain increased with the boys. Conclusions: Headaches, neck pain and backaches are common among 9th graders and it seems to be a relationship with time exposure to different screen activities. Further research investigating gender differences and pain is important, in particular among girls who seem to be more vulnerable. / Studiens syfte var att analysera niondeklassares självrapporterade skärmbaserade aktiviteter, fysisk inaktivitet samt muskuloskeletala symptom, smärtintensitet och påverkan i vardagen. Vidare var syftet att göra jämförelser med resultat från en tvärsnittsstudie år 2004 i samma skolor för att se eventuella skillnader. Frågeställningarna var: Hur ser sambandet ut med skärmbaserade aktiviteter, fysisk inaktivitet samt muskuloskeletala symtom, smärtintensitet och påverkan i vardagen? Finns några könsskillnader? Hur har muskuloskeletala besvär, inaktivitet och skärmbaserad tid förändrats i jämförelse med niondeklassare år 2004? Metod: En kvantitativ tvärsnittsstudie med enkäter som besvarades av 465 elever (85 %) på 11 skolor. Populationen hämtades från SIH projektet år 2004 som bestod av ett slumpmässigt urval från skolor i hela Sverige. Resultat: Mobiltelefonen användes av tre gånger så många flickor, TV spel av sju gånger så många pojkar. Surfplatta användes aldrig eller sällan av 80 %. Nackvärk och huvudvärk förekom ofta bland 68 % respektive 58 % av de som använde mobilen &gt;3 timmar eller mer. Ryggvärk förekom bland 19 % som tittade TV &gt; 3 timmar. Huvudvärk mer än en månad förekom dubbelt så ofta hos flickor och upplevdes ha en svår påverkan i vardagen. Dubbelt så många pojkar ansåg sig mest fysiskt aktiva i vardagen och ansåg sig likna den person som är mest fysiskt aktiv. Stillasittande tid var inte signifikant men en tredjedel av ungdomarna uppgav att de sitter stilla 7-9 h på vardag och 4-6 h på helgdag. Mellan år 2004 och år 2013 ökade förekomsten av huvudvärk och pågående ryggsmärta bland pojkar. Slutsats: Smärta i huvud, nacke och rygg är ofta förekommande bland niondeklassare och samband tycks finnas med långvarig exponering av olika skärmbaserade aktiviteter Självrapporterad smärta har i jämförelse med en tvärsnittsstudie år 2004 minskat förutom huvudvärk och ryggsmärta som ökat bland pojkar. Vidare forskning kring könsskillnader och smärta är angeläget i synnerhet bland flickor som är mer drabbade.

Context information brings new opportunities for efficient and effective applications and services on mobile devices. Many existing work exploit the context dependency of mobile usage for specific applications, and show significant, quantified, performance gains by utilizing context. In order to be practical, such works often pay careful attention to the energy and processing costs of context awareness while attempting to maintain reasonable accuracy. These works also have to deal with the challenges of multiple sources of context, which can lead to a sparse training data set. Even with the abundance of such work, quantifying context-dependency and the relationship between context-dependency and performance achievements remains an open problem, and solutions to manage the and challenges of context awareness remain ad-hoc. To this end, this dissertation methodologically quantifies and measures the context dependency of three principal types of mobile usage in a methodological, application agnostic yet practical manner. The three usages are the websites the user visits, the phone numbers they call, and the apps they use, either built-in or obtained by the user from the App Store . While this dissertation measures the context dependency of these three principal types of mobile usage, its methodology can be readily extended to other context-dependent mobile usage and system resources. This dissertation further presents SmartContext, a framework to systematically optimize the energy cost of context awareness by selecting among different context sources, while satisfying the system designer’s cost-accuracy tradeoffs. Finally, this thesis investigates the collective effect of social context on mobile usage, by separating and comparing LiveLab users based on their socioeconomic groups. The analysis and findings are based on usage and context traces collected in real-life settings from 24 iPhone users over a period of one year. This dissertation presents findings regarding the context dependency of three principal types of mobile usage; visited websites, phone calls, and app usage. The methodology and lessons presented here can be readily extended to other forms of context and context-dependent usage and resources. They guide the development of context aware systems, and highlight the challenges and expectations regarding the context dependency of mobile usage.

This thesis discusses the future of smart business applications on mobile phones and the integration of voice interface across several business applications. It proposes a framework that provides speech processing support for business applications on mobile phones. The framework uses Gaussian Mixture Models (GMM) for low-enrollment speaker recognition and limited vocabulary speech recognition. Algorithms are presented for pre-processing of audio signals into different categories and for start and end point detection. A method is proposed for speech processing that uses Mel Frequency Cepstral Coeffcients (MFCC) as primary feature for extraction. In addition, optimization schemes are developed to improve performance, and overcome constraints of a mobile phone. Experimental results are presented for some prototype applications that evaluate the performance of computationally expensive algorithms on constrained hardware. The thesis concludes by discussing the scope for improvement for the work done in this thesis and future directions in which this work could possibly be extended.

This project includes an implementation of an intelligent voice recognition assistant for Android where functionality on current existing applications on other platforms is compared. Until this day, there has not been any good alternative for Android, so this project aims to implement a voice assistant for the Android platform while describing the difficulties and challenges that lies in this task.

ABSTRACT   Title: Mobile Marketing: Study of ICA – Correlation between mobile marketing and customer loyalty Level: Master Degree in Business Administration Authors: Bolor Amarsanaa and Joshua Anjorin Supervisor: Ernst Hollander Date: 2012 – January Aim: Having loyal customers is a key for successful organizations. There is increased complexity and competitiveness in the market place as regards to what companies need to do and how to do them in meeting the needs of customers. Is that why companies today are exploring the potentials of mobile phones to ultimately earn customers’ loyalty? However, there is not much research done in this area, especially in finding correlation between mobile marketing and customer loyalty. Thus, this research aims to examine correlation between mobile marketing and customer loyalty. Method: Data collection methods included literature reviews, a questionnaire and interviews. These were analysed by hypothesising, comparing with theories, and the use of descriptive analysis, correlation, and other methods presented as discussions, tables, and charts. Results &amp; Conclusions: The theoretical and empirical research findings show that customer loyalty is positively related with mobile marketing. Use of mobile marketing such as mobile application, mobile web and SMS can perhaps enhance customer loyalty by meeting the demand of customers; increasing interaction and communication with customers; and increasing customer satisfaction. However, due to the research limitations and due to the fact that mobile marketing is a relatively new field of study, it needs some more time and more extensive research to make a general assumption about relationship between them and the strength of such relationship. Suggestions for future research: For further research, more extended research with broader samples is essential. It will be also crucial to investigate how much of an effect mobile marketing has on customer loyalty by scrutinizing company’s cost and profit measurements of mobile marketing besides opt-in and opt-out measurements of customers. Contribution of the thesis: We hope that this research has scratched the surface to this new field of study and made an addition to existing theory. It also stirs up interests in the emerging research on mobile marketing’s untapped potentials. Key words: Mobile Marketing, Customer loyalty, mobile phone, customer satisfaction, communication with customers.
