FRe building technological products

Nowadays "Flood Resilient (FRe) Building Technological Products" is an undefined concept, and concerned FRe solutions cannot be even easily identified. There is an interest in offering an identification and classification of the referred products, since it will be useful for stakeholders and populations at flood risk for adopting the most adequate protections when facing floods. There are many barriers for the implementation of "FRe building technological products", and particularly their standardization is still a major challenge. To put into contact such solutions with final customers, it appears necessary to protocolize them all. The classification effort achieved in this document shall be considered as a necessary preliminary step in order to open the road to the market to FRe building technological solutions.

Redundancy in interface design and its impact on intuitive use of a product in older users

Many older adults have difficulty using modern consumer products due to their complexity both in terms of functionality and interface design. It has been observed that older people also have more problems learning new systems. It was hypothesised that designing technological products that are more intuitive for older people to use can solve this problem. An intuitive interface allows a user’s to employ prior knowledge, thus minimizing the learning needed for effective interaction. This paper discusses an experiment investigating the effectiveness of redundancy in interface design. The primary objective of this experiment was to find out if using more than one modality for a product’s interface improves the speed and intuitiveness of interactions for older adults. Preliminary analysis showed strong correlation between technology familiarity and time on tasks, but redundancy in interface design improved speed and accuracy of use only for participants with moderate to high technology familiarity.

Approaches to designing for older adults' intuitive interaction with complex devices

Many older people have difficulties using modern consumer products due to increased product complexity both in terms of functionality and interface design. Previous research has shown that older people have more difficulty in using complex devices intuitively when compared to the younger. Furthermore, increased life expectancy and a falling birth rate have been catalysts for changes in world demographics over the past two decades. This trend also suggests a proportional increase of older people in the work-force. This realisation has led to research on the effective use of technology by older populations in an effort to engage them more productively and to assist them in leading independent lives. Ironically, not enough attention has been paid to the development of interaction design strategies that would actually enable older users to better exploit new technologies. Previous research suggests that if products are designed to reflect people's prior knowledge, they will appear intuitive to use. Since intuitive interfaces utilise domain-specific prior knowledge of users, they require minimal learning for effective interaction. However, older people are very diverse in their capabilities and domain-specific prior knowledge. In addition, ageing also slows down the process of acquiring new knowledge. Keeping these suggestions and limitations in view, the aim of this study was set to investigate possible approaches to developing interfaces that facilitate their intuitive use by older people. In this quest to develop intuitive interfaces for older people, two experiments were conducted that systematically investigated redundancy (the use of both text and icons) in interface design, complexity of interface structure (nested versus flat), and personal user factors such as cognitive abilities, perceived self-efficacy and technology anxiety. All of these factors could interfere with intuitive use. The results from the first experiment suggest that, contrary to what was hypothesised, older people (65+ years) completed the tasks on the text only based interface design faster than on the redundant interface design. The outcome of the second experiment showed that, as expected, older people took more time on a nested interface. However, they did not make significantly more errors compared with younger age groups. Contrary to what was expected, older age groups also did better under anxious conditions. The findings of this study also suggest that older age groups are more heterogeneous in their capabilities and their intuitive use of contemporary technological devices is mediated more by domain-specific technology prior knowledge and by their cognitive abilities, than chronological age. This makes it extremely difficult to develop product interfaces that are entirely intuitive to use. However, by keeping in view the cognitive limitations of older people when interfaces are developed, and using simple text-based interfaces with flat interface structure, would help them intuitively learn and use complex technological products successfully during early encounter with a product. These findings indicate that it might be more pragmatic if interfaces are designed for intuitive learning rather than for intuitive use. Based on this research and the existing literature, a model for adaptable interface design as a strategy for developing intuitively learnable product interfaces was proposed. An adaptable interface can initially use a simple text only interface to help older users to learn and successfully use the new system. Over time, this can be progressively changed to a symbols-based nested interface for more efficient and intuitive use.

Diferença entre homens e mulheres na propensão em adotar produtos e serviços tecnológicos

The construct Technology Readiness (TR) and its instrument of measure Technology Readiness Index (TRI) defined by Parasuraman (2000), refer to people¿s propensity to adopt digital technological products and services. The TR can be viewed as an overall state of mind resulting from mental drivers and inhibitors related to optimism, innovativeness, discomfort and insecurity. These facets combine into a complex way for produce distinct groups of individuals (explorers, pioneers, skeptics, paranoids and laggards) with different traits of behaviors connected to the adoption of technological products and service. This study had as its objective to evaluate the applicability of the TRI in the Brazilian context, through the replication of the scale on a sample of 336 adults consumers (168 men and 168 women) resident in the state of the Rio de Janeiro, segmented by age groups, educational level and monthly family income. The results show that, in the sample analyzed, as culturally the technology is linked to values of a male society, men presented a higher propensity in adopting technological products and services than women. However, this hypothesis was not confirmed in the analysis segmented by age groups.

Fábrica de software: até que ponto fordista?

Due to the crisis over rigid automation that occurred around 1960, management models essentially fordist, have gradually become more flexible. The software factories, however, that emerged in the nineties manufacturing the most advanced technological products, adopted eminently fordist controls and seem to be going contrary to the evolutionary cycle that organizations tend to follow. The alternation between rigid and flexible management models of these software factories, observed under continuum fordism (0) ______ (1) post-fordism, as well as the limitations of the metaphor that emerges given the nature of the software they manufacture, constitutes the object of the study.

Avances tecnológicos y obsolescencia programada

El objetivo seguido en este proyecto fin de carrera, ha sido el análisis de la evolución general de la tecnología, tanto electrónica, como en Telecomunicaciones e Informática, desde sus inicios hasta la actualidad, realizando un estudio sobre cómo esos avances han mejorado, incluso cambiado nuestra vida cotidiana y cómo a consecuencia de la conversión de muchos de estos productos tecnológicos en objeto de consumo masivo, la propia dinámica económico-comercial ha llevado a las empresas a la programación del fin del su vida útil con el objeto de incrementar su demanda y, consiguientemente, la producción. Se trata de lo que se conoce desde hace décadas como Obsolescencia Programada. Para realizar este documento se ha realizado un breve repaso por los acontecimientos históricos que promovieron el inicio de esta práctica, así como también nos ha llevado a realizar mención de todos esos aparatos tecnológicos que han sufrido una mayor evolución y por tanto son los más propensos a que se instauren en ellos, debido a cómo influyen dichos cambios en los consumidores. Otro de los aspectos más importantes que rodean a la Obsolescencia Programada, es cómo influye en el comportamiento de la sociedad, creando en ella actitudes consumistas, que precisamente son las que alimentan que el ciclo económico siga basándose en incluir esta práctica desde el diseño del producto, puesto que a mayor consumo, mayor producción, y por tanto, supone un aumento de beneficios para el fabricante. Aunque, lo que para algunos supone un amplio margen de rentabilidad, existen otros componentes de la ecuación que no salen tan bien parados, como pueden ser los países del tercer mundo que están siendo poblados de basura electrónica, y en general el medio ambiente y los recursos de los que hoy disponemos, que no son ilimitados, y que están viéndose gravemente afectados por la inserción de esta práctica. Como cierre de este análisis, se repasarán algunas de las técnicas empleadas en algunos de los productos más utilizados hoy en día y las conclusiones a las que se han llevado después de analizar todos estos puntos del tema. ABSTRACT. The main goal followed in this final project has been analyzing the overall evolution of technology, both electronics and telecommunications. Also, computer science; from beginning to present it has been realized some studies about these advances have improved our daily life, even changing our routine, and turn us massive consumers of all technological products on the market. This dynamic economic and commercial has led companies to programming the end of its useful life in order to increase demand, and consequently, the production. This is known as Obsolescence. To make this document has been made a brief review through historical events that promoted the opening of this practice, and also led us to make mention all these technological devices have undergone further evolution and therefore more likely to establish them, because these changes affect consumers. Another important aspect around planned obsolescence is how to influence in society’s behavior, creating consumerist attitudes, which are precisely those feed the economic cycle continues to be based on including this practice from product design, because increased consumption and production. Therefore, this fact increases profits for the manufacturer. Although, for some people suppose a wide margin of profitability, there are other components do not have such luck; for example, third World countries have been filled with e-waste and the environment, in general, and resources available today which are not unlimited, and who are seriously affected by the inclusion of this practice. To close this analysis, we will review a few techniques used in some products most widely used today, and the conclusions that have been made after analyzing all these points of the topic.

Restrição externa, dependência estrutural de commodities primárias e o investimento direto externo no Brasil

As the beginning of the discussion about the reprimarization process of the Brazilian exportations, or about a deindustrialization process of the country foreign sales, this study purpose that the discussion, actually, should be about the existence of the commodities structural dependence as a way to face the foreign restrictions. Therefore the intention is to show that, historically, the way that the Brazilian economy has crossed for its development depends of the foreign capital, mainly in its way of Foreign Direct Investment (FDI), and in the balance generated by the primary products, which make us try to understand the impact of this capital for the equilibrium of the Brazilian Payment Balance and also for the economy. These points were discussed not only based on the Brazilian classic writers as Francisco Oliveira, Caio Prado Jr. and Celso Furtado, but also using the newest studies which contributes to point the causes and consequences of the external capital dependence in the actual scenario. The conclusions acquired in the end of the study, indicates the fact that the Brazilian specialization in products of low aggregated value is not recent. Brazil is, historically, a competitive country in primary products. At the same time, the country importation always was a pressure factor of the National Payments Balance, being composed by products with more aggregated value. According to some authors, this characteristic of the Brazilian Economy will be surpassed with the economic opening process, which will attract external capital making possible the modernization of the Brazilian productive sector. Therefore, we can claim that the FDI, in the way it has been inserted in the country, does not offer the opportunity to get out of the commodities dependence, as generators of the payment balances, because the country international competitive standard didn t get any important changes, keeping itself out of the step related to the global standard which has been intensified in products with more aggregated value. The changes in the national insertion standard directed to more technological products is really important to surpass the historical scenario of commodities dependence, making the country less vulnerable to external crisis.

Konsumenters uppfattning och kännedom om hållbar produktion och konsumtion : Teknologiska produkter och mobiltelefoner

Sambandet mellan konsumtion och klimatförändringar blir mer tydligt och jordens naturresurser som utarmas kan enligt forskning helt tillskrivas mänskligt beteende. För att lösa denna kris behöver delvis konsumentbeteendet förändras och konsumenter behöver välja mer hållbara produkter. Den överkonsumtion som finns idag är ett stort hot mot en hållbar utveckling och svenska konsumenter är en grupp som är snabba att konsumera det nyaste på marknaden. Konsumtionen av teknologiska produkter som exempelvis mobiltelefoner, datorer och tv-apparater har ökat kraftigt under de senaste tjugo åren då dessa produkter har blivit en del av konsumentens vardag. Nya modeller av mobiltelefoner kommer ständigt ut på marknaden och mobiltelefonen är en av de teknologiska produkterna där konsumtionen har ökat kraftigt. Syftet med denna uppsats var att undersöka konsumenters uppfattning och kännedom om hållbar produktion och konsumtion av teknologiska produkter. Mobiltelefonen är den teknologiska produkt som valdes som studieobjekt. Vi valde att genomföra en kvalitativ metod med semistrukturerade intervjuer för att uppfylla syftet. Intervjuerna genomfördes med tio studenter vid olika utbildningsprogram vid Högskolan Dalarna. Resultatet visade att konsumenters generella uppfattning och kännedom om hållbar produktion och konsumtion av teknologiska produkter var låg. Det fanns en viss kännedom om hållbarhetsfrågor hos våra respondenter men ingen hade tidigare reflekterat över detta i samband med produktion och konsumtionen av teknologiska produkter. Uppfattningen hos respondenterna är i stor utsträckning att produktion och konsumtion har påverkan på den hållbara utvecklingen.

Cereal products for specific dietary requirements. Evaluation and improvement of technological and nutritional properties of gluten free raw materials and end products

Coeliac disease is one of the most common food intolerances worldwide and at present the gluten free diet remains the only suitable treatment. A market overview conducted as part of this thesis on nutritional and sensory quality of commercially available gluten free breads and pasta showed that improvements are necessary. Many products show strong off-flavors, poor mouthfeel and reduced shelf-life. Since the life-long avoidance of the cereal protein gluten means a major change to the diet, it is important to also consider the nutritional value of products intending to replace staple foods such as bread or pasta. This thesis addresses this issue by characterising available gluten free cereal and pseudocereal flours to facilitate a better raw material choice. It was observed that especially quinoa, buckwheat and teff are high in essential nutrients, such as protein, minerals and folate. In addition the potential of functional ingredients such as inulin, β-glucan, HPMC and xanthan to improve loaf quality were evaluated. Results show that these ingredients can increase loaf volume and reduce crumb hardness as well as rate of staling but that the effect diverges strongly depending on the bread formulation used. Furthermore, fresh egg pasta formulations based on teff and oat flour were developed. The resulting products were characterised regarding sensory and textural properties as well as in vitro digestibility. Scanning electron and confocal laser scanning microscopy was used throughout the thesis to visualise structural changes occurring during baking and pasta making

Integration practices for the technological innovation of products: Case studies at two large technological companies

Studies on innovation and technology management have emphasized the importance of integration between the research and development (R&D) department and others involved with the product development process (PDP) as a relevant practice for the good performance of technological innovation of product activities. This study addresses the topic of transfers of technologies to new product projects and also integration practices between the R&D department and others involved with the PDP. A qualitative study was conducted that was operationalized through two case studies at large high-tech companies: One is Brazilian and the other is a multinational subsidiary in Brazil. Among its main result, this paper represents and analyzes management practices that are favorable to integration in product development projects that demand development and transfer of technologies, such as: participation of R&D personnel in market activities, the adoption of virtual interaction mechanisms, and the application of methods such as technology roadmaps. © Universidad Alberto Hurtado, Facultad de Economía y Negocios.
