The goal of study 1 was to use a remote eye tracker to understand how eye movements change with 7 geometrically varied remote controls to determine design element saliency. 20 participants were used to measure the following eye metrics: number of fixations prior to first fixation of any AOI, time to first fixation of an AOI, number of fixations on an AOI, dwell time of the first fixation on an AOI, total dwell time of an AOI, and the percentage of time spent on an AOI. The results of the study showed that all participants spent between 75-85% of their time fixated on the button layout which was not defined as an AOI. No statistical differences were found in the values measured for all eye tracking metrics across similarly defined AOIs. In study 2, the objective was to determine attitudes towards appearance and usability of the 7 remote control designs using the participants from study 1. Participants were asked to rate their attitudes and preferences, using a Likert-based questionnaire, about the qualities of appearance and usability for the attributes of proportion, shape, and configuration. They were asked open-ended questions about their likes and dislikes regarding the qualities of appearance and usability. Lastly, participants were given a pairwise comparison survey where they chose their preferred remote design, based on appearance, for 10 paired sets of contrasting remote designs. The hourglass subjacent and hourglass round designs were rated highest for appearance and usability from the Likert questionnaire. The hourglass round design was ranked highest for the pairwise comparison survey. For study 3, the goal was to determine attitudes towards appearance and usability of the 7 remote designs with online participants. 300 participants were asked to rate their attitudes and preferences using the same Likert-based questionnaire from study 2. They were asked the same open-ended questions and administered the same pairwise comparison survey as in study 2. The results of the Likert questionnaire showed that the hourglass subjacent and hourglass round designs were rated highest for appearance and usability. From the pairwise comparison survey, the hourglass round design was ranked the highest.

Tesis por compendio / [EN] The determination of genetic biomarkers is progressively becoming more extended and popular, being commercialized even in kits for personalized medicine. Establishing specific genotype variations for each patient, such as single nucleotide polymorphisms (SNPs), could be a fundamental tool in the field of diagnosis, prognosis and therapy selection. However, the use of DNA testing is not fully implemented in general healthcare, mainly due to technical and economic barriers associated to the current technologies, which are limited only to specialized centers and large hospitals. In this thesis, the main goal was to overcome these obstacles by developing simpler, faster and more affordable point-of-care (POC) genotyping systems. Allele discrimination was achieved by employing isothermal enzymatic reactions, like recombinase polymerase amplification (RPA), ligation of oligonucleotides and loop-mediated isothermal amplification (LAMP). These processes were integrated to colorimetric indicators and immunoenzymatic assays, in a microarray format. Using compact discs and polycarbonate chips as platforms, the detection was achieved through widespread electronics, like disc-reader, flatbed scanner and smartphone. To demonstrate their capacities, the resulting systems were applied for identifying SNPs in human samples, associated to therapies for tobacco smoking cessation, major depression disorder and blood clotting-related diseases. After selecting the proper conditions, all studied strategies discriminated SNPs in samples containing as low as 100 copies of genomic DNA, with an error rate below 15%. Most importantly, the developed methods have reduced assays times varying between 70 and 140 minutes, at a cost similar to a conventional PCR-based analog, but maintaining or raising amplification efficiency and eliminating the need of specialized temperature cyclers and fluorescence scanners. In conclusion, the biosensors based in isothermal reactions and consumer electronics devices greatly improve the competitivity of POC DNA analysis. It was demonstrated that the technologies developed in this thesis could support genotyping assays in low-resource areas, such as primary healthcare centers and emerging countries. Through this democratization of genetic testing and by performing adequate association studies, molecular diagnostics and personalized medicine practices could have their application extended to the clinical routine. / [ES] La determinación de biomarcadores genéticos es cada vez más extensa y popular, estando incluso comercializándose kits para medicina personalizada. Establecer las variaciones específicas en el genotipo de cada paciente, como los polimorfismos de un solo nucleótido (SNP) podría ser una herramienta fundamental en el campo del diagnóstico, pronóstico y selección de la terapia. Sin embargo, el uso de pruebas de ADN no se encuentra completamente implementado en la atención médica general, principalmente debido a las barreras técnicas y económicas asociadas a las tecnologías actuales, limitadas solamente a centros especializados y grandes hospitales. En esta tesis, el objetivo principal fue superar estos obstáculos mediante el desarrollo de sistemas de genotipado point-of-care (POC), más simples, rápidos y asequibles. La discriminación alélica se logró mediante el uso de reacciones enzimáticas isotermas, como la amplificación de la recombinasa polimerasa (RPA), la ligación de oligonucleótidos y la amplificación isotérmica mediada por bucle (LAMP). Estos procesos se integraron a indicadores colorimétricos y ensayos inmunoenzimáticos en formato de micromatriz. Utilizando discos compactos y chips de policarbonato como plataforma de ensayo, se ha logrado la detección mediante dispositivos electrónicos de consumo, como un lector de discos, escáner documental y teléfono móvil. Para demostrar sus capacidades, los sistemas resultantes se aplicaron a la identificación de SNPs en muestras humanas, asociados a terapias antitabaquismo, para depresión y enfermedades relacionadas con la coagulación de la sangre. Tras seleccionar las condiciones adecuadas, todas las estrategias estudiadas discriminaron SNPs en muestras conteniendo tan solo 100 copias de ADN genómico, con una tasa de error inferior al 15%. Más importante, los métodos desarrollados han reducido los tiempos de ensayo a valores entre 70 y 140 minutos, a un coste similar a un análogo convencional basado en la reacción en cadena de la polimerasa (PCR), pero manteniendo o aumentando la eficiencia de amplificación y eliminando la necesidad de termocicladores y escáneres de fluorescencia. En conclusión, los biosensores basados en reacciones isotérmicas y dispositivos de electrónica de consumo mejoran en gran medida la competitividad del análisis POC de ADN. Se ha demostrado que las tecnologías desarrolladas en esta tesis podrían apoyar los ensayos de genotipado en áreas de recursos escasos, como centros de atención primaria y países emergentes. A través de esta democratización de las pruebas genéticas y realización estudios de asociación adecuados, el diagnóstico molecular y las prácticas en medicina personalizada podrían extender su aplicación a la rutina clínica. / [CA] La determinació de biomarcadors genètics és cada vegada més extensa i popular, estant fins i tot comercialitzant-se kits per a medicina personalitzada.

This study sought to understand factors driving repurchase intentions for consumer electronics (CE) hardware and in particular mobile phones. The outcome of the study was expected to be of interest in academia and practice because it develops upon existing literature and identifies actionable variables that could be used to optimise market offerings. Based on a literature review it was hypothesised that the intent was driven by hedonic and utilitarian factors. These included conspicuousness and visibility; product bundling; reliability; technological features, usability of the product and the buyers’ age. The study tested these hypotheses using primary data. The method was employed to confirm the postulated drivers as well as to determine the direction of the effects. Data collection was conducted through a cross sectional internet survey enumerated in August 2010. The survey reached a broad sample of 144 responders. The analysis supported two of the six hypothesised drivers. The supported drivers were conspicuousness and usability. The recommendation was therefore to encourage the CE industry to focus on creating aesthetically appealing, fashionable devices that were intuitively easy to use requiring minimal assistance or product manuals. It also recommends that less emphasis be placed on durability, advanced features, on bundling additional extras and on targeting particular age groups.

Most companies' desire is to create customer relationships and the working methods have changed as a result of the increased e-commerce. Because of digitalization, the retailing field has changed dramatically. Consequently, physical stores are facing competition from online companies. Previous literature has stated that physical stores now have to focus on what happens inside the store in order to generate a pleasant experience. The research question focused on examining how Elgiganten, the largest consumer electronic store in Sweden, use customer experience and customer value in order to influence store attractiveness. This was carried out by using a qualitative approach, an exploratory nature and by conducting in-depth interviews with consumers and the company's head managers. The main findings of this study suggest that customers can not take advantage of some services when buying through e-commerce. This ability to provide service is an important part of the handling of competition from e-commerce. The retailers need to find the right balance between engagement and emotions in the physical retail environment in order to appeal to the consumers’ desires of trust & reliability in order to create an attractive experience point. By means of this, the thesis emphasised the imperative of creating experience in offline retailing.

This thesis develops a method to optimize the inventory-related performance of a VMI (Vendor Managed Inventory) in retailing environments, for two successive products with overlapping lifecycles, under stock-dependent demand. The study refers to existing research in different fields, such as inventory policies and VMIs, retailing of substitutable products, stock-dependent demands and product lifecycle management. However, no study encompassing all these research streams could be found, and thus an abductive approach is developed, aiming at building new theory. The thesis draws upon a case study at Sony Germany, which has started an ambitious VMI initiative with the largest retailer of consumer electronics products in Germany. First, stock and sales data available, along with insights collected among employees, is used to understand the key profit-drivers when lifecycles of the two products overlap, and a set of indicators is propounded to measure them. The pattern of sales in relation to inventories of the two products is studied, and results in the validation of the stock-dependent demand assumption, with demand following a Poisson distribution of parameter λ [on-hand stock]. Demand for the new product is also found to be negatively affected by stock levels of the old product, in an exponential way. Second, a model is built and a scenario- based simulation embedding the patterns previously established is performed to evaluate different strategies to steer the stock levels in the VMI. Scenarios are evaluated against the proposed set of indicators, but no scenario is found to over perform consistently the others. Nevertheless interesting patterns emerge and it is possible to relate the performance observed to specificities of scenarios and product contexts. Using the patterns identified, a set of guidelines is suggested, along with proposals for practical implementation.

This thesis developed out of my personal curiosity on the subject of high-technological development. Specifically, high-technology’s shift from primarily a military tool to a consumer product raised several questions to answer since first taking an interest in the subject. My lifestyle, like many other Americans in my generation, incorporates computers, cell-phones, and video game consoles as not only an innovative tool, but a standard and necessary mode of production. In our contemporary society, technology is obtainable everywhere. As an entertaining tool in the form of video games to a productivity tool in our workplaces, most individuals have assimilated consumer electronics. Yet this essay seeks to look at the beginning of these changes in the late 1970’s and 1980’s. Particularly, how did an American society that based itself around industrial mechanisms suddenly become so enthralled by consumer electronics, which a decade before were used for missile guidance and complex mathematical calculations? How did these devices, which were initially proposed as an industrial and political efficiency tool, suddenly become a labeled consumer luxury good? The answer to these questions surprisingly developed into a more complex socioeconomic analysis of 1970’s and 1980’s behaviors that utilized a Marxist interpretation of the relationship between technology and the human experience. This topic incorporates terms and theories from a variety of academic subjects. While this essay is formed around a historical narrative and argument, much of the evidence is acquired from economical, sociological, and psychological resources. As a result, I hope readers of this essay will find it as enlightening and enjoyable as my own personal journey within the subject.

This study examines how a user-centered approach can influence product design to reduce physical discomfort when using in-ear true wireless. The given study is a collaboration with the consumer electronics company Zound Industries. The purpose has been to understand the origins of why physical discomfort can arise when using in-ear true wireless headphones and to what extent the user behaviour plays in it all. Previous studies have shown how physical discomfort in the form of eczema, itching and soreness has been caused by the use of in-ear true wireless. Based on user-centered methods such as expert interviews, cultural probes, user interviews, focus groups, this study has been able to identify not only how, but why physical discomfort can occur when using in-ear true wireless. Furthermore, the study has also been able to identify behavioural patterns among users that reveal how headphones are used for purposes other than what they are intended for. It has been possible to show how users use their headphones like an earplug without music to block out sound in order to be able focus or to communicate they don’t want to be disturbed to avoid social interactions. The conducted knowledge and insights provide a better understanding of how design can be used to enhance the experience of using in-ear true wireless headphones. Applying design strategies within design for behavioural change, an adjustable headphone has been developed that allows the user to use the headphone according to the needs of the user. The study provides a basis for how design can be better utilised in future in-ear true wireless headphones.

Hållbarhet är ett aktuellt ämne i dagens samhälle och nämns ofta i mediesammanhang. Planeten är överbefolkad, människor svälter och levnadsstandarden skiljer sig markant mellan jordens kontinenter. Även jordens resurser används i större mån än vad planeten klarar av och detta leder i sin tur till att miljön blir lidande. Detta har bidragit till att samhället idag har höga krav på hur företag arbetar kring hållbarhet. Intressenternas krav har i sin tur lett till att upprättande av hållbarhets- redovisningar har blivit allt vanligare. Syftet med denna uppsats är att undersöka hur hållbarhetsredovisningar utformas i tre olika branscher i Sverige och jämföra dessa för att urskilja eventuella likheter och olikheter som kan finnas. Vidare kommer även alternativa förklaringar till likheterna och olikheterna framföras. Branscherna som har studerats är hemelektronikbranschen, klädbranschen och livsmedels- branschen. För att besvara studiens syfte och frågeställningar har en djupgående analys av 15 företags hållbarhetsredovisningar gjorts. Sedan har dessa företag jämförts för att ha möjlighet att urskilja eventuella likheter och olikheter. Utifrån det empiriska materialet kan det utläsas att utformningen av de granskade rapporterna är olika till utseendet men att innehållet är relativt likt. Dock finns det ett fåtal skillnader i innehållet vilket kan bero på vilken miljö som respektive företag är aktiva i och vilka krav intressenterna har på ett företags hållbarhetsarbete. Likheter mellan branscherna och företagen kan förklaras med hjälp av legitimitetsteorin och den institutionella teorin. Företag vill uppnå legitimitet gentemot samhället i stort och det kan göras genom att efterlikna de företag som upprättar framgångsrika hållbarhetsrapporter. Studien är en kartläggning av hållbarhetsredovisningar i tre olika branscher där likheter och olikheter framhävs samt eventuella förklaringar till varför företag utformar sin hållbarhetsredovisning på de sätt de har gjort. / Sustainability is an up-to-date issue and it’s often mentioned in media. The planet is overpopulated, people are starving and the living conditions differ significantly between the continents. The resources of the earth are used to a greater extent than the planet is capable of. This has led to environmental problems and that the society has high demands of corporate social responsibility. Stakeholders’ requirements have led to the fact that the establishment of sustainability reports has become more common. The purpose of this thesis is to examine how sustainability reports are designed in three different industries in Sweden and compare them to distinguish any similarities or differences that may exist. Further, alternative explanations for the similarities and differences will be made. The industries that have been studied are the following: consumer electronics industry, clothing industry and food industry. In order to answer the study's purpose and questions, an in-depth analysis of 15 companies’ sustainability reports has been made. Then a comparison has been made between these companies and industries in order to determine if there are any similarities or differences. Based on the empirical material, the design of the reviewed reports is different in appearance but the content is relatively similar. However, there are also a few differences in the content and these may depend on the environment for which each company is active and what kind of requirements its stakeholders have on the company's sustainability work. Similarities between the industries and companies can be explained with the help of legitimacy theory and institutional theory. Companies want to achieve legitimacy towards the society and one way to do this is to imitate the companies that establish successful sustainability reports. The study is a mapping of sustainability reports in three different industries, highlighting similarities and differences, as well as possible reasons why companies design their sustainability report in the way they have done.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This study is based on the Law 12.305/2010 (National politics on Solid Waste), which has progressed in in the field of sustainability, by transmitting a strong educational and awareness value. However, the increasing demand and offer of new technologies has caused in the population a big and increasing desire for consumption. In this sense, the objective of the research came to life, through the Law nº 12.305/2010, from the extension of the instrument in the reverse logistics of the consumer electronics in face of the consuming society and the capitalism market, both agents that use the planned obsolescence and perceived in spite of environmental balance. The central question proposed to be answered is presented in the following form: aware the ecological caos created/caused by the consuming society and the capitalist market, which incorporate the practice of planned obsolescence and perceived, it is asked if the reverse logistics instrument, brought by the Law that set up the National politics on Solid Waste, is it enough to strike/reduce the excess of consumer electronics surplus? Bringing to the real case, what is the situation of the consumer electronics waste in the city of Santa Maria/RS? The approach method utilized was the dialect. The theoretical framework presents itself from a base critical theory Zigmunt Baumam and Enrique Leff. The procedure method adopted was the case study, and the metodological instrument to data collection was the interview guidelines technic. It was studied, iniatialy, the consuming society and the capitalist market, emphasizing the planned obsolescence strategies programmed and perceived, and the cultural aspect tied to the consum; later, it was made a counterpoint in face of the National politics on Solid Waste and their main directives, explaining the collectors of recyclable material situation, the post-consumer responsibility and the shared liability, and contextualizing the reverse logistics instrument regarding the consumer electronics waste and, finaly, it was presented the counterpoint through the situation of the consumer electronics waste in the city of Santa Maria/RS. In the end, it was observed that the reverse logistics of the consumer electronics waste was not enough to strike or reduce the exceeding of consumer electronics waste, only contributes to the reducing the generation of these waste, in a minor percentage, because the planned obsolescence strategies and perceived practice by the market prevail in spite of the environment preservation and protection. There is a long road to go in the city of Santa Maria to reduce the distance between text (of law) and context (environmental reality) and to reach the desired minimum in the environmental related questions, with respect to consumer electronics waste. / Este trabalho apresenta-se a partir da Lei 12.305/2010 (Política Nacional de Resíduos Sólidos), a qual avançou muito no campo da sustentabilidade, transmitindo um forte caráter educativo e conscientizador. Entretanto, a crescente demanda e a oferta de novas tecnologias têm provocado na população um grande e crescente desejo de consumo. Nesse sentido, o objetivo da pesquisa emergiu, à luz da Lei nº 12.305/2010, da extensão do instrumento da logística reversa de eletroeletrônicos diante da sociedade do consumo e do mercado capitalista, bem como da realidade sobre os resíduos eletroeletrônicos na cidade de Santa Maria/RS. A pergunta central que se propõe a responder apresentou-se da seguinte forma: tendo em vista a desordem ecológica causada/gerada pela sociedade do consumo e pelo mercado capitalista, que incorporam a prática da obsolescência programada e percebida, indaga-se se o instrumento da logística reversa, trazido pela Lei que instituiu a Política Nacional de Resíduos Sólidos, é suficiente para combater/diminuir o excesso de resíduos eletroeletrônicos? E, trazendo para o caso concreto, qual a situação dos resíduos eletroeletrônicos na cidade de Santa Maria/RS? O método de abordagem utilizado foi o dialético. O marco teórico apresenta-se a partir de uma teoria de base crítica, fundada em Zigmunt Baumam e Enrique Leff. O método de procedimento adotado foi o estudo de caso, e o instrumento metodológico para coleta de dados foi a técnica da entrevista por pautas. Trabalhou-se, inicialmente, com a sociedade do consumo e a lógica do mercado capitalista, destacando as estratégias da obsolescência programada e percebida, e o aspecto cultural atrelado ao consumo; num segundo momento, fez-se o contraponto diante da Política Nacional de Resíduos Sólidos e suas diretrizes principais, esclarecendo a situação dos catadores de materiais recicláveis, a responsabilidade pós-consumo e a responsabilidade compartilhada, e contextualizando o instrumento da logística reversa em relação aos resíduos eletroeletrônicos; e, finalmente, apresentou-se o resultando do contraponto através da situação dos resíduos eletroeletrônicos na cidade de Santa Maria/RS. Ao final, constatou-se que a logística reversa de resíduos eletroeletrônicos não é suficiente para combater ou diminuir o excesso de resíduos eletroeletrônicos, apenas contribui para a redução da geração desses resíduos, em percentual muito pequeno, porque as estratégicas da obsolescência programada e percebida praticadas pelo mercado predominam em detrimento da preservação e proteção do meio ambiente. E que há um longo caminho a ser percorrido na cidade Santa Maria para diminuir a distância entre texto (da lei) e contexto (realidade socioambiental) e para alcançar o mínimo desejado em relação às questões ambientais, especialmente, no que tange aos resíduos eletroeletrônicos.
