Social Media Integration in Video Games GameNshare: A Social Overlay for Desktop Games

The ever increasing popularity of social media makes it a promising source for the personalization of gameplay experiences. Furthermore, involving social network friends in a game can greatly enrich the satisfaction of the player and also attract potential novel players to a game. This master thesis describes a social overlay designed for desktop games, called GameNshare. It allows players to easily capture and share with multiple social networks game-related screenshots, videos and stories. Additionally, it also provides asynchronous multiplayer game mechanics to directly integrate social network friends in the game. GameNshare was designed to interact with the users in a non-intrusive way allowing them to be in complete control of what is shared. It prevents unsolicited sharing of messages, a key problem in social media integration tools, by the use of built-in message monitoring and anti-spam measures. GameNshare was specially designed for players aged from 18 to 25 years that are regular users of Twitter and Facebook. It was tested by a group of 10 individuals from the target age range that were surveyed to capture their insights on the use of the social overlay. The implemented GameNshare features were well accepted by the testers that were also useful in highlighting features for future development. GameNshare ultimate goal is to make players look and ask for social integration and allow them to take full advantage of their social communities to improve gaming experiences.

Tecnologias Multimédia no Apoio ao Ensino da Assistência Pré-Hospitalar

Vivemos num mundo em constante mudança, onde a evolução tecnológica está cada vez mais presente no nosso quotidiano e as suas influências são inúmeras nas nossas vidas. Por outro lado, a vida humana é algo extremamente valioso e único pelo que a sociedade, também nessa área, tem procurado evoluir e dotar-se de novos meios e mecanismos de atuação, que possibilitem um socorro rápido e adequado em situações que possam em algum momento pôr em perigo a vida do ser humano. Pretendemos com o presente estudo, correlacionar estas duas vertentes, a do socorro á vítima para apoio á vida humana e a tecnologia no sentido de contribuir para uma formação mais distribuída mas ao mesmo tempo capaz de transmitir conhecimentos necessários á formação dos que socorrem. Para o efeito, planeamos o desenvolvimento de um Objeto de Aprendizagem (OA) denominado CiTAT (Curso Interativo de Tripulante de Ambulância de Transporte) que tem como objetivo acrescentar valor a todos os que são obrigados a frequentar o curso em regime presencial de Tripulante de Ambulância de Transporte (TAT). Após uma fase de análise do estado da arte relacionada com este tipo de formação, e após termos percebido como funciona e que tipos de recursos utilizam, analisámos temas relacionados com este tipo de formação como o “Sistema Integrado de Emergência Médica” o “Exame á Vítima”, o “Suporte Básico de Vida” e as “Emergências de Trauma”. Percebemos que a mudança de paradigma de formação das pessoas passou a ter novas formas de distribuir conhecimento em formato digital e que proporciona aos formandos um ensino distribuído em formatos de e-learning ou de b-learning. Os Objetos de Aprendizagem (OA) parecem assumir um relevo especial no ensino da área da saúde, abordando áreas temáticas e proporcionando aos seus utilizadores mecanismos de autoavaliação após a visualização dos conteúdos pedagógicos. Após o desenho do modelo concetual do CiTAT, avançamos para a produção de recursos necessários para a sua integração no OA. Após uma fase de testes e ajustes, avançamos para a sua avaliação final por parte dos utilizadores e preparamos um questionário para aferir o potencial de utilização deste tipo de soluções no ensino de TAT, atendendo ao facto de ser uma formação obrigatória e cuja recertificação é feita de três em três anos. O passo final foi a sua distribuição ao nível global, sendo o CiTAT catalogado com metadados e colocado no repositório MERLOT.

Monitoring Abacavir Bioactivation in Humans: Screening for an Aldehyde Metabolite

The anti-HIV drug abacavir is associated with idiosyncratic hypersensitivity reactions and cardiotoxicity. Although the mechanism underlying abacavir-toxicity is not fully understood, drug bioactivation to reactive metabolites may be involved. This work was aimed at identifying abacavir-protein adducts in the hemoglobin of HIV patients as biomarkers of abacavir bioactivation and protein modification. The protocol received prior approval from the Hospital Ethics Committee, patients gave their written informed consent and adherence was controlled through a questionnaire. Abacavir-derived Edman adducts with the N-terminal valine of hemoglobin were analyzed by an established liquid chromatography-electrospray ionization-tandem mass spectrometry method. Abacavir-valine adducts were detected in three out of ten patients. This work represents the first evidence of abacavir-protein adduct formation in humans. The data confirm the ability of abacavir to modify self-proteins and suggest that the molecular mechanism(s) of some abacavir-induced adverse reactions may require bioactivation.

Echinococcus granulosus sensu lato GENOTYPES IN DOMESTIC LIVESTOCK AND HUMANS IN GOLESTAN PROVINCE, IRAN

Cystic echinococcosis (CE) is a globally parasitic zoonosis caused by larval stages of Echinococcus granulosus. This study investigated E. granulosus genotypes isolated from livestock and humans in the Golestan province, northern Iran, southeast of the Caspian sea, using partial sequencing data of the cytochrome c oxidase subunit 1 (cox1) and NADH dehydrogenase 1 (nad1) mitochondrial genes. Seventy E. granulosus isolates were collected from animals in slaughterhouses: 18 isolates from sheep, 40 from cattle, nine from camels, two from buffaloes and one from a goat, along with four human isolates (formalin-fixed, paraffin-embedded tissues) from CE patients of provincial hospitals. All isolates were successfully analysed by PCR amplification and sequencing. The sequence analysis found four E. granulosus genotypes among the 74 CE isolates: G1 (78.3%), G2 (2.7%), G3 (15%) and G6 (4%). The G1-G3 complex genotype was found in all of the sheep, goat, cattle and buffalo isolates. Among the nine camel isolates, the frequency of G1-G3 and G6 genotypes were 66.7% and 33.3%, respectively. All four human CE isolates belonged to E. granulosus sensu stricto. This study reports the first occurrence of the G2 genotype in cattle from Iran and confirms the previously reported G3 genotype in camels in the same country.

Differential exploitation of cashew - a low conflict crop - by sympatric humans and chimpanzees

Modification of natural areas by human activities mostly has a negative impact on wildlife by increasing the geographical and ecological overlap between people and animals. This can result in escalating levels of competition and conflict between humans and wildlife, for example over crops. However, data on specific crops and crop parts that are unattractive to wildlife yet important for human livelihoods are surprisingly scarce, especially considering their potential application to reducing crop damage by wildlife. Here we examine the co-utilization of a nationally important and spatially abundant cash crop, cashew Anacardium occidentalis, by people and chimpanzees Pan troglodytes verus inhabiting a forested–agricultural matrix in Cantanhez National Park in Guinea-Bissau. In this Park people predominantly harvest the marketable cashew nut and discard the unprofitable fruit whereas chimpanzees only consume the fruit. Local farmers generally perceive a benefit of raiding by chimpanzees as they reportedly pile the nuts, making harvesting easier. By ensuring that conflict levels over crops, especially those with high economic importance, remain low, the costs of living in proximity to wildlife can potentially be reduced. Despite high levels of deforestation associated with cashew farming, these findings point to the importance of cashew as a low-conflict crop in this area.

Robots and humans as co-workers? The human-centred perspective of work with autonomous systems

The design of work organisation systems with automated equipment is facing new challenges and the emergence of new concepts. The social aspects that are related with new concepts on the complex work environments (CWE) are becoming more relevant for that design. The work with autonomous systems implies options in the design of workplaces. Especially that happens in such complex environments. The concepts of “agents”, “co-working” or “human-centred technical systems” reveal new dimensions related to human-computer interaction (HCI). With an increase in the number and complexity of those human-technology interfaces, the capacities of human intervention can become limited, originating further problems. The case of robotics is used to exemplify the issues related with automation in working environments and the emergence of new HCI approaches that would include social implications. We conclude that studies on technology assessment of industrial robotics and autonomous agents on manufacturing environment should also focus on the human involvement strategies in organisations. A needed participatory strategy implies a new approach to workplaces design. This means that the research focus must be on the relation between technology and social dimensions not as separate entities, but integrated in the design of an interaction system.

Fixed-mobile integration

Often, fixed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile networks are distorted upwards, amplifying any incumbency advantage. As concerns potential remedies, a uniform off-net pricing constraint leads to higher welfare than functional separation and even allows to maintain some of the efficiency gains.
