According to the dual-process recognition models, the retrieval of information from long-term memory is supported by recollection and familiarity. Alzheimer’s disease is consistently found to affect recollection. As for familiarity, however, no consensus has been reached so far. Some studies are in favor of an early impairment of familiarity, while others are in favor of a preservation of familiarity in the mild and moderate stages of the disease. This lack of consensus can be partly explained by methodological differences between studies. We discuss three methodological dimensions: the type of recognition test, the type of paradigm for estimating familiarity and recollection, and the nature of the material used. These differences reveal the complex nature of familiarity which would be underlied by different mechanisms that may be selectively altered or preserved in the disease. [less ▲]

Precision livestock farming is emerging in the wake of the technological developments in remote sensing and motion monitoring. Tools are developed to allow accurate real time monitoring of the individual cattle behaviour in a quest to improve the management of pastures. Studies have shown the relevancy of accelerometers in the analysis of behaviour using dedicated devices. Accelerometers are located either close to the mouth or jaw of the animal or on its forehead or neck. Records are usually performed at low frequency (<1Hz) and most studies classify behaviours using neuronal networks or multivariate statistical approaches, with little consideration to the animals’ actual movements. Inertial measurement units (IMU) in consumer mobile devices are specifically developed to record accurately user movements. Besides 3D-accelerometer, they can include 3-D rotational speed sensors, 3-D magnetometers and GPS. Optimised power consumption offers significant autonomy. Data directly acquired from the sensors and IMU signals from build-in proprietary algorithms can be recovered using user-friendly low-cost applications. Moreover, mobile devices can store or communicate information by wireless in real time at high frequency. As movements of cattle are in the same range as humans, this study investigates the relevancy of mobile devices IMU signals to discriminate main behaviours of cattle on pasture. [less ▲]

In this paper, we are interested in estimating the out-of-sample predictive ability of a set of trading rules. Usually, this ability is estimated using a rolling-window sample-splitting scheme, true out-of-sample data being rarely available. We argue that this method makes a poor use of the available information and creates data mining possibilities. Instead, we propose an alternative bootstrap approach, based on the .632 bootstrap principle, that makes a full use of the data at hand and decreases data mining occasions. This method enables to compute a robust estimator of the out-of-sample predictive ability of a trading rule by generating both in-sample and out-of-sample bootstrap data. These data are later used to measure the performance over a large range of scenarios. We illustrate our methodology on IBM and Microsoft daily stock prices, where we compare 11 trading rules specifications, with a total of 11,668 parametrizations. Our results showed that the out-of-sample performance of all rules decreases strongly compared to the in-sample performance. For the datasets considered, two different filter rule specifications have the highest out-of-sample mean excess returns. However, all tested rules have mean excess returns close or below zero, suggesting that none of these rules can truly generate a profit, nor beat a simple buy-and-hold strategy. [less ▲]

Le droit des étrangers connaît des développements incessants : les réformes du cadre législatif belge se succèdent à une cadence accélérée, l'Union européenne investit le champ en imposant diverses obligations aux Etats membres, qui touchent aujourd'hui la quasi-totalité des questions posées par le séjour des étrangers. A ces nouveautés législatives se conjugent une influence croissante de la Cour européenne des droits de l'homme dont le contentieux constitue de plus en plus souvent un dernier recours pour l'étranger. Le présent ouvrage a comme ambition de donner aux praticiens quelques clés de lecture de ce droit aux contours sans cesse renouvellés. Pour ce faire, il débute par un panorama général, sous forme de guide pratique, des principes généraux qui structurent le droit de l'entrée et du séjour sur le territoire belge. Après cette introduction dont l'objectif est de permettre de bien comprendre les différents 'entrées' possibles sur le territoire belge, les auteurs, tous spécialistes des questions qu'ils analysent, abordent quelques uns des status les plus importants qui permettent aux étrangers de séjourner sur le territoire belge. Ces statuts font l'objet d'un éclairage qui met l'accent tant sur les nouveautés que sur les difficultés les plus récurrentes rencontrées en pratique. La récente réforme qui a modifié en profondeur les règles d'acquisition de la nationalité belge fait également l'objet d'un commentaire approfondi. Les différentes contributions s'attachent à préciser les contours d'une jurisprudence et d'une pratique mouvante, tout en dévoilant les enjeux concrets et en esquissant des réponses aux questions que la pratique devra affronter prochainement.

This paper offers a critical overview of the law of Belgian nationality as it stands in 2014, focusing in particular on the many changes brought about by the Act of 4 December 2012. In a first chapter, the paper outlines the main changes which were adopted in 2012. In a second chapter, the paper attempts to offer a critical analysis of these changes, using various angles such as the imperative of coherence, the principle of legal certainty or the position of international developments in the reform. Some attention is also paid to the comparative aspects of nationality law. [less ▲]

Traditional foods play a major role in the diet of rural people living in the Tibet Autonomous Region of the People's Republic of China. Because these foods are mainly derived from local agriculture as well as artisanal production, their mineral composition may show significant discrepancies when compared with food composition data. This study aims at providing relevant data on the mineral composition of the main Tibetan foods. Sixteen different foodstuffs were sampled, including water, concentrated brewed black tea, chang, tsampa, wheat flour, dried cheese, dried yak meat, dried mutton, blood sausage, dried wild peaches, dried Chinese radish, and dried nettles. They were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) for 19 minerals: Na, K, P, Ca, Mg, Fe, Zn, Mn, Cu, Ni, Se, Mo, Al, As, Cr, Co, Cd, Pb, and V. The validity of the results was ensured by the use of standard reference materials. A statistical comparison of the mean mineral contents of the analyzed foods against food composition data from the China Food Composition (CFC) table was carried out. It revealed significant discrepancies, emphasizing the importance of food analysis for nutritional assessment in Tibet autonomous region. To the best of our knowledge, the mineral compositions of some traditional Tibetan foods are here reported for the first time. [less ▲]

The practice of “incident reporting” is commonly recognized as an effective mean to reduce the vulnerability of “at risk” socio-technical systems (e.g. nuclear plants, large industrial facilities or hospitals), as it allow the concerned community to learn from past incidents. Indeed, it is assumed that collective resilience will be upgraded via the use of institutionalized Incident Reporting System (IRS), enabling the organization to improve the quality of the actions and reactions in case of deviation from normality, or to prevent such deviation. Yet, inductive analysis of what happens with those IRS in practice are not numerous. In this paper, we address this gap and display the results of semi-structured interviews conducted in a nuclear facility. During those interviews, participants were also requested to produce a mind map of the IRS they are concerned with. As a result, we show that safety is a matter of solidarities that are situated in specific contexts. To that regard, incident reporting is a practice of decomposition and recomposition of trusts and thus of solidarities. Reporting incidents consists in putting solidarity on trial, as the collective safety was threatened. We show that such open trial is often avoided because questioning solidarities is not always desirable in order to allow the group to continue functioning. Overall, we argue that informal reporting behaviors can also contribute to upgrade collective resilience without putting solidarities on trial. [less ▲]

Medications often partially alleviate the symptoms of RLS patients, emphasizing the need for finding alternative treatments. Recent studies reported an efficacy of bright light therapy (BLT) in Parkinson disease. RLS pathogenesis involves the dopaminergic system and light has been shown to influence the dopaminergic tone. Therefore, the objective of our study was to determine the therapeutic value of three weeks of BLT on RLS symptoms severity, sleep quality, daytime somnolence, circadian rhythms and mood. [less ▲]
