Quick Response eller QR är en teknik som tillåter snabb och pålitlig optisk läsning av information som är kodad i ett rutmönster. Som läsverktyg kan man använda läsare som är speciellt tillverkade för ändamålet och numera också vanliga smartphones. Tekniken har i flera år varit framgångsrik i vissa industriella applikationer såsom lagerhållning, men det är fortfarande osäkert i vilken utsträckning den också kan vinna insteg i vardagligt användande av smartphones. Vi har genomfört en enkätundersökning bland universitetsstudenter för att uppskatta hur spridd användningen av QR-koder är och hur denna användning ser ut. För att analysera resultatet har vi använt oss av teorin om diffusion of innovations som tillhandahåller en modell för spridning av ny teknik inom ett sammanhang. Resultaten antyder försiktigtvis att kännedom om tekniken är väl spridd, men att användandet är begränsat och att det beror på brist på upplevd nytta snarare än på att tekniken skulle vara otillgänglig eller svårhanterlig. / Quick Response or QR is a technology allowing fast and reliable optical reading of information encoded in a pattern of black and white squares. Reading implements include devices designed especially for this purpose as well as, in recent years, ordinary smartphones. The technology has for some time been successful in industrial applications such as storage management, but it is uncertain to what degree it might also see widespread use in everyday use of smartphones. We conduct a questionnaire-based survey targeting university students in order to estimate the extent and nature of QR usage. In analysing our findings we make use of the theory of diffusion of innovations, which provides a model for the adoption of a new technology within a given context. Our results imply that knowledge of the technology is widely dispersed, but that actual use is limited and that this is due to a lack of perceived usefulness rather than the technology as such being inaccessible or difficult to use.

<p>Hemp (Cannabis sativa L.) is an annual crop used to produce a wide range of products including foods, beverages, nutritional supplements, fabrics, and textiles. Hemp has long been conflated with marijuana and has not been grown in the United States for decades. Due to recent legislation, the legal restrictions on growing hemp seem likely to be lifted. However, although interest is high, industrial hemp has not been grown in the U.S. for nearly 80 years and research on virtually all aspects of hemp production in the U.S. is in its infancy. We lack fundamental knowledge regarding cultivar performance, interactions with pests, particularly weeds, and nutrient requirements. Research is needed to address this knowledge gap and potential production issues as well as to determine the attitudes, perceptions and concerns of farmers regarding the potential adoption of this “new” crop. Importantly, research should be conducted before the crop becomes widely available so that farmers can make informed decisions and avoid costly mistakes. My dissertation consists of four chapters. In Chapter 1, I examine the literature for weed management in hemp production and identify research gaps. In Chapter 2, I investigate the complex legal framework that surrounds Cannabisand the resulting complications for hemp production. In Chapter 3, I present research conducted to determine the attitudes, perceptions, interests and concerns of organic farmers regarding the reintroduction and potential adoption of hemp was completed through survey research. Finally, in the fourth chapter, I present research conducted to characterize the growth and phenology of industrial hemp cultivars and identify cultivars suitable for growing conditions in the Midwest, and to determine the effect of delayed planting on the phenology and growth of seed and fiber hemp varieties in the Midwest.</p><p>Weed control and weed management in industrial hemp production is a surprisingly understudied field. Few peer-reviewed field studies on hemp exist on any subject and in particular, weed control and weed management is understudied. Specifically, only three studies designed to address a weed management issues exist in the literature dating back to 1900. Most commodity crops have extensive literature discussing weed management, and such an extensive gap in the hemp literature suggests that research needs to be conducted to determine the impacts of weeds on hemp production. Discrepancies among state laws and current federal drug legislation have created a convoluted, confusing, and impractical framework currently surrounds hemp production in the U.S. The building of pesticide regulation and product safety systems that are specific to the many end uses of Cannabis have yet to occur in the U.S. Interactions between producers, state and federal government, and third-party testing laboratories need to be facilitated to build regulation systems along with educational programs to train growers appropriate best management. Organic farmers are generally considered less risk adverse than the general farming population and often considered early adopters of technology. I surveyed organic farmers in seven Midwestern states and found that 98.5% of the respondents were generally open to new technologies, but that demographics variables explained little of the variation for respondents’ level of innovativeness as well as their openness to hemp.The respondents were generally open to hemp production (88.2% agreed with the statement that they were open to trying hemp production on their farm) and found that attributes of hemp production that conferred relative advantage and were compatible with existing systems were important. Delayed planting of hemp generally reduced the onset and duration of female flowering and the time to seed formation but the magnitude of these effects varied among cultivars. Seed, stalk, and total above ground dry weight yields varied across cultivar and planting date which may have been impacted by inconsistent stand densities stemming from heavy rainfall and wet soils. Results from this dissertation suggest that hemp is an understudied crop in the U.S., but that interest in its production among organic farmers exists. Field results support the importance of both planting date and cultivar for hemp phenology discussed in previous literature and so research needs to be conducted to explore best hemp production practices in the U.S.<br></p><p></p>

No. of bitstreams: 1 Marcio Carneiro dos Santos.pdf: 13468296 bytes, checksum: ba0aa41f643f1555600334a06c82c741 (MD5) Previous issue date: 2014-04-29 / As the experience of what we call watching TV replicates in different screens and displays, dematerializes to move away from its traditional technical support, while it extends or expands from hybridizations and new possibilities, we face the challenge to continue thinking about watching TV and media in general, driven, among other reasons, by the increasing centrality of the media in the world in which we live. To anchor this study on technological change and its impact on the ontological essence of what was considered before as clear and precise , we choose the case of the deployment of the Brazilian Digital Terrestrial Television process - SBTVD -T , in particular from its technical characteristic that legislation and scholars decided to call interactivity and, in simplified form, is the possibility that , in a broadcast television system, along with the transmission of audio and video, a data stream in the form of software can be added, small programs called interactive applications that can be accessed by the viewer . Despite its innovative potential, interactivity in broadcast television in Brazil, as a technological solution, faces several difficulties for its diffusion. In this research, by using a systemic approach and methodology of Van Dijk who analyses similar processes in terms of technology, content, uses and appropriations, property, governance and business models, we propose to examine this scenario. By conducting a critical analysis from the assumptions above, we have identified the conflict between the agendas of the involved groups and the distance imposed to audiovisual professionals, craftsmen producing content, that have few participation in a process driven primarily by engineers and software developers. Within this framework, we ve translated the theoretical trajectory in an applied path to the development of an authoring solution for creating interactive applications in standard SBTVD -T focused on non-programmers. The tool, called T - Autor, has had its registration with INPI and nowadays is undergoing testing in actual production environments / À medida que a experiência do que chamamos de assistir TV se replica em telas e displays diversos, se desmaterializa ao se afastar do seu suporte técnico tradicional, ao mesmo tempo em que se amplia ou expande a partir de novas hibridizações e possibilidades; encaramos o desafio de continuar pensando sobre ela e os meios de comunicação de forma geral, impelidos, entre outros motivos, por uma centralidade cada vez maior da mídia no mundo em que vivemos. Para ancorar esse estudo sobre transformações tecnológicas e seu impacto ontológico na própria essência do que antes considerávamos como claro e preciso, escolhemos o caso do processo de implantação do Sistema Brasileiro de Televisão Digital Terrestre SBTVD-T, em especial a partir da sua característica técnica que legislação e academia decidiram chamar de interatividade e que, de forma simplificada, consiste na possibilidade de, num sistema de televisão aberta, junto com o a transmissão de áudio e vídeo, acrescentarmos um fluxo de dados, na forma de software, ou seja, pequenos programas ou aplicações interativas que podem ser acessadas pelo telespectador. Apesar do seu potencial inovador, a interatividade em TV aberta no Brasil, enquanto solução tecnológica enfrenta diversas dificuldades para sua difusão. Nesse trabalho utilizando uma abordagem sistêmica e a metodologia de Van Dijk que observa processos semelhantes em termos de tecnologia, conteúdo, usos e apropriações, propriedade, governança e modelos de negócio, nos propomos a analisar esse cenário. Fazendo uma análise crítica das premissas acima, identificamos o conflito entre as agendas dos grupos envolvidos e o distanciamento a que foram submetidos os profissionais do audiovisual, artífices da produção de conteúdo, que pouco participaram de um processo guiado basicamente por engenheiros e desenvolvedores de software. A partir desse quadro, traduzimos o percurso teórico da tese numa vertente aplicada, com o desenvolvimento de uma solução de autoria para criação de aplicações de interatividade no padrão do SBTVD-T focada em não programadores. A ferramenta, denominada T-Autor, já teve seu registro efetivado junto ao INPI e hoje se encontra em fase de testes em ambientes reais de produção

Skincare products were deemed as socially undesirable for men in the past days. Images of men were expected to be tough, independent, hard-boiled, whereas skincare products were too feminine for men. However, due to the metro-sexual fashion trend which advocating men to dress up themselves, men nowadays are starting to care about their outfits, appearances and facial skin condition to which women are paying attention. The market of skincare products for men in Taiwan now is rapidly growing and do not confine to only a small amount of men users. It is a widely received conscious that men need skincare products. Hence, from only a few early adopters to wide spread adopters in men population as whole, the purpose of this study is to investigate the correlations between demographic, media usages, personal characteristics, impulsive consumption behaviors and adopting stages. By using survey method, this study wants to explore whether there are any significance in demographic, media usages, personal characteristics affecting men to adopt skincare products. However, Diffusion of Innovation theory is under the premise of social learning theory, which presupposes that it is a rational decision making process for consumer when adopting innovation. The presupposition as such disregards the possibility of impulsive consumption. In addition to demographic, media usages, personal characteristics, this study takes impulsive consumption into consider as a independent variable affecting adoption. The study results is that when compared with no taking impulsive consumption into consideration, there are significances in demographic, media usages, personal characteristics affecting men to adopt skincare products after controlling impulsive consumption as a independent variable. The study results show that impulsive consumption is an indispensable variable when researching diffusion of innovations.

The e-book reader has become one of the most popular consumer electronics goods since the Amazon Kindle first launched in the end of year 2007; it has led the trend of e-book worldwide. E-book reader not only sold very well in North America, the sales increased very fast in Asia and Europe. According to FIND (2010), the global total sales of e-book reader is 3.6 million pieces in 2009, and it increased almost 80% in 2010. This shows that the e-book reader has become more and more popular. Taiwan is the most important country of e-book reader supply chain, which not only predominate the key techniques and patent but also takes OEM / ODM orders worldwide. Despite the advantage of the hardware development, the use of e-book readers is not common in Taiwan. Therefore the purposes of this research are to explore the factors that would influence user¡¦s adaptive behavior of e-book readers. This research based on technology acceptance model (TAM), and extends with ¡§Compatibility¡¨, ¡§Observability¡¨ and ¡§Perceived complementarity¡¨ as external variables to investigate the factors influencing consumer usage of e-book reader. The analytical results are as below: 1. ¡§Compatibility¡¨ has positive significant effect on both ¡§Perceived Usefulness¡¨ and ¡§Perceived Ease of Use.¡¨ 2. ¡§Observability¡¨ has positive significant effect on both ¡§Perceived Usefulness¡¨ and ¡§Perceived Ease of Use.¡¨ 3. ¡§Perceived complementarity¡¨ has positive significant effect on both ¡§Perceived Usefulness¡¨ and ¡§Perceived Ease of Use,¡¨ but has no significant effect on¡§Behavioral Intention.¡¨ 4. Both ¡§Perceived Usefulness¡¨ and ¡§Perceived Ease of Use¡¨ have positive significant effect on¡§Behavioral Intention.¡¨

With the rapid Internet development, E-auction is also popular in recent years. In E-auction, the rating is the most effective indicator that can provide a referral for buyer and seller. In addition, buyers can use rating mechanism as feedback to respond their satisfaction after they bought goods. In the other hand, the rating of seller could reflect his transaction history before. When the positive rating is more, which means satisfied and successful transaction is more also, and represents that seller¡¦s credit accumulation. This study uses innovation diffusion model to analyze the seller¡¦s growth trend of rating, critical mass of rating by real data, classify sellers that equal to cluster analysis and discuss further. The samples are the sellers who sell t-shirt in eBay from December 1 in 2010 to January 31 in 2011. We get 8,304 sellers¡¦ data, and pick 116 of them randomly as samples, which are fit in with our research requests. This research is to answer three research questions. The first research question is to verify that growth trend of rating could fit in with diffusion of innovation, then, to analyze and discuss the growing trend and the rating accumulation. That result does verify that rating accumulation fit in with diffusion of innovation, and growing trend fit in with S-shaped curve. Furthermore, rating raise at first if it is affected by external influence, like key searching, website payment advertisement. On the contrary, the rating increases quickly for some time that the seller has good reputation if the rating is affected by internal influence, like word of mouth. The second research question is to calculate the critical mass of rating by Bass model. The result shows that the rating accelerates when it reaches critical mass between 1129 and 1402, it represents the seller accumulates considerable sale amount and customer satisfaction, and also let potential buyers more confident and promote their willingness to purchase. In addition, it can represent the sellers have enough experience and can provide the better marketing strategies when the sellers¡¦ rating reaches critical mass of rating. The third research question is to divide the sellers by cluster analysis and investigate. The result shows the diverseness between the growth trend of rating, the critical mass of rating, product price, and buyer repeated purchase. This study can provide a referral for the novice sellers, and they can develop their marketing strategy base on their characteristics of product.

Since the merge of global media, the usage of digital cable is becoming popular in Taiwan. Even though the development of digital cable is difficult, the cable companies realize it is necessary to promote digital cable. Therefore, how do the companies meet the needs of the enormous cable consumers. The first steps are to understand the characteristics of earlier users, focus on target consumers and control and the opportunities of market are definitely becoming very popular topics. This research is based on Rogers¡¦s ¡§Diffusion of Innovations Theory¡¨. It includes five types, profitability¡Bcompatibility¡Bcomplexity¡Busage¡Band observation. This research is to test whether the digital cable meets the characteristics of new technology media. It also discusses the characteristics of earlier adopters based on the change of population, socio-economic status, personality and the trend of media. At the same time, we also examine the difference of samples between 97 cable consumera and 198 non-cable consumers. This helps us to understand the innovation characteristics of earlier adopters. From this research we will discover the similar characteristics of digital cable and other new media technologies. The early adopters except in the population variable of marriage and the personality characteristic embodiment ability, the fate idea, risk withstanding and so on three kind of special characteristics with the non- user, socio-economic status and I communication behavior special characteristic, the two has reveals the difference, therefore we can know sex, the age, the education level, the income condition and communication pathway, user level in digital cable TV uses or not the key aspect. Moreover, this study find out domestic digital cable TV or relative industry can be their promoting reference, at the same time the researcher also give them suggestion for their research and relative research in the future.
