Online consumer behavior: The tablet shopper – A new kind of customer?

Tablet computers are on the rise and are increasingly superseding stationary computers in terms of modern online shopping. This paper therefore aims on understanding how tablet and website characteristics might impact online consumer behavior. The collected data resulted from focus groups and in-depth interviews conducted with a technology affine audience. It has shown that tablets indeed may have shifted shopping behavior from utilitarian towards rather recreational attributes. Discussions also revealed high customer expectations towards visited shopping websites and prevailing deficits. Thus, harnessing the concept of experiential flow is crucial. Compelling experiences are required to increase the duration of stay and consequently the likelihood of increased purchases.

Perfil do doente com infecção do trato urinário num serviço de ortopedia

RESUMO - As infecções do trato urinário são um problema constante nas unidades prestadoras de cuidados de saúde. Sabe-se que a incidência das mesmas é das mais elevadas em termos de infecções associadas aos cuidados de saúde, bem como acarretam fortes custos hospitalares devido ao aumento da demora média de internamento, uso de antibioterapia aumentado, entre outros. De modo a tentar compreender toda esta problemática, com a realização deste trabalho de projecto, pretende-se encontrar o perfil do doente com infecção do trato urinário num serviço de Ortopedia. Através deste mesmo perfil, tornar-se-á mais fácil uma vigilância epidemiológica e intervenções mais direccionadas ao problema em questão. Para tal, pretende-se construir um instrumento de colheita de dados que caracterize o doente de uma forma geral, antes, e durante o próprio internamento. Caso este mesmo instrumento fosse aplicado, pretender-se-ia cruzar as váriáveis concluindo eventualmente o perfil, justificando melhor o facto da existência de infecções urinárias e adequando medidas de prevenção. ------------ -ABSTRACT - The urinary infections are a constant problem in the health care facilities. It is known that the incidence of these infections is one of the biggest in terms of infections associated to health care, as well as they bring higher hospital costs, due to the middle delay of internment, the increased use of antibioterapy, as long as others. In the way of trying to understand all problems, with the realization of this work project, one intends to find the profile of the orthopedic patient with urinary infection, in the Orthopedic Service. Trough this same profile, it will be easier to do an epidemiological surveillance and more directed interventions to the problem in matter. To achieve this goal, it is claimed to build an instrument of data collection that characterizes the patient in a general way, before and during the internment. If this instrument would be applied, it would be intended to cross the variables concluding eventually the profile, justifying better the fact of the existence of urinary infection

Combining WLAN fingerprint-based localization with sensor data for indoor navigation using mobile devices

This project proposes an approach for supporting Indoor Navigation Systems using Pedestrian Dead Reckoning-based methods and by analyzing motion sensor data available in most modern smartphones. Processes suggested in this investigation are able to calculate the distance traveled by a user while he or she is walking. WLAN fingerprint- based navigation systems benefit from the processes followed in this research and results achieved to reduce its workload and improve its positioning estimations.

Functional characterization and directed engineering of redox proteins for a rational improvement of Bioelectrochemical systems

In recent years, new methods of clean and environmentally friendly energy production have been the focus of intense research efforts. Microbial fuel cells (MFCs) are devices that utilize naturally occurring microorganisms that feed on organic matter, like waste water, while producing electrical energy. The natural habitats of bacteria thriving in microbial fuel cells are usually marine and freshwater sediments. These microorganisms are called dissimilatory metal reducing bacteria (DMRB), but in addition to metals like iron and manganese, they can use organic compounds like DMSO or TMAO, radionuclides and electrodes as terminal electron acceptors in their metabolic pathways.(...)
