The Université du Québec à Trois-Rivières , established in 1969 is a campus of the Université du Québec, located in Trois-Rivières, Quebec. The university has 12,500 students in 8 different campuses, including the main one in Trois-Rivières. About 1000 of them come from overseas, from 60 countries. The university has given more than 74,000 diplomas since its founding. The Trois-Rivières campus also holds a large library with about 400,000 documents. Wikipedia.

The attentional blink (AB) refers to the difficulty in reporting a second target (T2) presented shortly after a first target (T1) in a stream of distractors. The goal of the present study was to investigate distractor-based interference in the AB by recording the P3 component of the event-related potential to both targets. An intertarget distractor was presented at lag 1 (T1+1), at lag 2 (T1+2), or at neither of these two lags (no distractor). T2 was always presented at lag 3, as the last item in the stream. In two experiments, the P3 from T1 was attenuated in the T1+1 condition compared to the two other distractor conditions. In absence of a task switch (Experiment 1), the P3 from T2 was delayed in both the T1+1 and T1+2 conditions. In the presence of a task switch (Experiment 2), the P3 from T2 was delayed only in the T1+1 condition. Results demonstrate that intertarget distractors can modulate the AB directly but only in absence of a task switch. © 2015 Society for Psychophysiological Research. Source

Quantum Bayesianism, or QBism, is a recent development of the epistemic view of quantum states, according to which the state vector represents knowledge about a quantum system, rather than the true state of the system. QBism explicitly adopts the subjective view of probability, wherein probability assignments express an agent’s personal degrees of belief about an event. QBists claim that most if not all conceptual problems of quantum mechanics vanish if we simply take a proper epistemic and probabilistic perspective. Although this judgement is largely subjective and logically consistent, I explain why I do not share it. © 2015, The Author(s). Source

Objective: This article describes the results of a study analyzing several discourses on the values of occupational therapy and some philosophical assumptions upon which these values are based. Method: A qualitative study of several values statements using the hermeneutical method-a conventional analytical approach in philosophy-was conducted. Results: The literature review reveals that opinions on the values of occupational therapy differ greatly-no one value is shared among all the values statements examined. However, the majority of the texts mention occupational participation. A philosophical analysis of the literature shows that this value is based on a conception of human beings that can be traced back to the philosophical anthropologies of thinkers like Marx, Rousseau, Sartre, and Kant. The philosophical analysis also brought to light a certain conceptual confusion about what a value is. Conclusions: This article therefore offers some conceptual clarifications to help distinguish between values, beliefs, attitudes, principles, and non-evaluative concepts. It also presents the implications for practice of this philosophical analysis of values statements of the profession. © 2014 Informa Healthcare. Source

Clinical Anatomy

The use of eponyms in medical sciences generally, and in anatomy specifically, remains controversial. In principle, this discussion should have been concluded as far back as 1895 (publication of the first Nomina anatomica): all eponyms should have been removed from the anatomical vocabulary then. In practice, what was believed to be a mere formality proved much more difficult to apply. Most eponyms remain in current use; moreover, their number goes on increasing. Assuming that there's no smoke without fire, we wondered why it seems impossible to get rid of a specific kind of term. The aim of this article and its successor is to weigh up the pros and cons. © 2014 Wiley Periodicals, Inc. Source

In this paper, an adaptive fuzzy control scheme is introduced for permanent magnet synchronous machines (PMSMs). The adaptive control strategy consists of a Lyapunov stability-based fuzzy speed controller that capitalizes on the machine's inverse model to achieve accurate tracking with unknown nonlinear system dynamics. As such, robustness to modeling and parametric uncertainties is achieved. Moreover, no explicit currents loop regulation is needed, which simplifies the control structure and unlike other control strategies, no a priori offline training, weights initialization, parameters knowledge, voltage, or current transducer is required. The system's convergence and stability are proved by Lyapunov stability theory, which yields an improved performance. Simulation results for different situations highlight the performance of the proposed controller in transient, steady-state, and standstill conditions. Furthermore, the adaptive fuzzy systems inherent parallelism makes them a good candidate for implementation in real-time PMSM drive systems. © 2011 IEEE. Source
