Amour, ¿una película hanekiana?

En el presente texto se realiza un análisis de la última cinta del director austríaco Michael Haneke: Amour (2012), mismo que lleva a proponer que se trata de un filme distinto del resto de la obra de este director, con cintas caracterizadas por ganarse el rechazo de críticos y espectadores promedio, ya que se trata de películas violentas y muy críticas. Sin embargo, con Amour, Haneke se ha vuelto del gusto popular

A game as a tool for empirical research on the shamanic interface concept

Comunicação apresentada na SciTecIn15 - Conferência Ciências e Tecnologias da Interação, realizada em Coimbra, de 12-13 de novembro de 2015A Shamanic Interface is a recent concept that posits that the acknowledgment of culture in gestural commands may contribute to richer and more powerful user interaction with abstract concepts and complexity, but has a lack of empirical validation. Hence, this paper presents a game developed as an empirical research tool for data collection and testing on shamanic interfaces. The game is a small maze where users use gestures to control a character to reach the end of each level. The control gestures performed by each user are captured with a Leap Motion controller and recognized through Hidden Markov Models. Three command sets were implemented: Portuguese cultural gestures, Dutch cultural gestures, and a generic set. This paper evaluates the game with different users to check its playability. We conclude that the game can be used as a research data-collection tool as is, but also acknowledge several playability-related improvement recommendations

Surface solitons in two-dimensional quadratic photonic lattices

We study two-color surface solitons in two-dimensional photonic lattices with quadratic nonlinear response. We demonstrate that such parametrically coupled optical localized modes can exist in the corners or at the edges of a square photonic lattice, and we analyze the impact of the phase mismatch on their properties, stability, and the threshold power for their generation.Comment: 3 double-column pages,5 figures, submited to Optics Letter

Predictive factors for cesarean delivery : a retrospective study

Background: Cesarean section rates have risen markedly worldwide. Considering the potential harm caused by this mode of delivery, and the general concern in reducing its incidence, it would be useful to individualize the risk of non-planned cesareans, and if there is any possibility, reduce that risk, and anesthesiologists should take part of this risk evaluation. In recent studies, many factors have been related with a higher risk of cesarean, and controversy still surrounds labor analgesia impact on cesarean risk. The aim of this study was to search for predictive factors for nonplanned cesarean delivery. Methods: Retrospective analysis of all labors occurred in our Obstetric Department during 2014. Maternal related factors, previous obstetric history, birth weight and factors related to labor analgesia and labor progression were studied. Our primary outcome was cesarean delivery. Results: We identified two independent predictive factors for cesarean delivery: birth weight (p=0,007 OR= 1,001 CI 95% [1,0003; 1,002]) and labor length since beginning of analgesia (p<0,0001 OR= 1,00005 CI 95%[1,00003; 1,00007]). Searching correlation between registered variables, maternal body mass index was positively associated with newborn birth weight (p<0.0001, R=0.157). Conclusion: Our study showed that birth weight and labor length since beginning of epidural analgesia are independent predictor factors of non-planned cesarean delivery. Furthermore, birth weight was associated with maternal body mass index, providing health professionals a modifiable factor in which we can intervene to improve outcome. As labor progression to cesarean is of major obstetric and anesthetic concern, multidisciplinary initiatives are warranted to clearly identify important variables concurring to operative delivery.info:eu-repo/semantics/publishedVersio

Internationalization to Colombian market: enablersand constraints

International business studies have reached more importance in the era of globalization where we live and, a deep analysis of specific markets, under specific conditions (like happens in this study) is always important to complement the existent literature. The current research attempts to study the main enablers and constraints faced by Portuguese companies during the internationalization process to the Colombian market, and its impact on organisational performance. Additionally, the current research attempts to define the best strategy possible to work around the challenges identified in order to obtain higher advantages to enter this country. It was used a hybrid strategy with multi data collection methods and sources. Data were collected through two methods: face-to-face interviews and questionnaires, both applied to Portuguese companies, with international business activities in Colombia and knowledge of the market, by their own experience. The sample collected represents 10% of the 387 Portuguese companies with businesses with the country in study, registered in 2018. The results showed that there is no evident of a positive influence of the enablers, neither a negative influence of the constraints on companies performance. Important insights are delivered to the Portuguese mangers succeed in internationalization process to Colombia

The effects of the quantity of physical activity in cognition

Mestrado em Exercício e SaúdeExercise promotes the increase of cognitive performance (Aberg et al., 2009), however, the quantity of physical activity needed to achieve this effect is not clearly defined. The present study aimed to research the effects of the quantity of physical activity practice on the executive function of healthy adults, measured by performance on the Stroop test. Results showed that the sedentary group had a worst performance than both groups of physically active individuals. Interestingly, this positive effect of exercise on cognitive performance did not increase with the increase in the quantity of physical activity practiced by the individuals. In conclusion, a moderate quantity of practice (150 min per week) produces the highest amount of benefits for cognitive performance, in comparison with a high quantity of practice (300 min per week)
