Discursive Strategies to Negotiate Power Relations in Disability Services Client Juries
2020
Collaboration with clients is an efficient way to develop social services. To strengthen the possibilities for clients to influence services, client juries are established. However, collaboration in the juries is perceived as difficult because of the power imbalance inherent in the client–social worker relationship. The aim of this study was to examine how the participants negotiated power relations in client jury meetings. The data consisted of four observed disability services client jury meetings. Analysis was performed using action-implicative discourse analysis, which aims to define different communicative problems, interactional strategies, and situated ideals of communicative practic…
The Three Steps of Clustering in the Post-Genomic Era: A Synopsis
2011
Clustering is one of the most well known activities in scientific investigation and the object of research in many disciplines, ranging from Statistics to Computer Science. Following Handl et al., it can be summarized as a three step process: (a) choice of a distance function; (b) choice of a clustering algorithm; (c) choice of a validation method. Although such a purist approach to clustering is hardly seen in many areas of science, genomic data require that level of attention, if inferences made from cluster analysis have to be of some relevance to biomedical research. Unfortunately, the high dimensionality of the data and their noisy nature makes cluster analysis of genomic data particul…
BIOMASS UTILIZATION AS A RENEVABLE ENERGY SOURCE IN POLISH POWER INDUSTRY – CURRENT STATUS AND PERSPECTIVES
2015
The depletion of the conventional energy sources, as well as the degradation and pollution of the environment by the exploitation of fossil fuels caused the development of renewable energy sources (RES), including biomass. In Poland, biomass is the most popular renewable energy source, which is closely related to the obligations associated with the membership in the EU. Biomass is the oldest renewable energy source, and its potential, diversity and polymorphism place it over other sources. Besides, the improvement in its parameters, including an increase in its calorific value, resulted in increasing use of biomass as energy source. In the electric power industry biomass is applied in the p…
Upper limits on the isotropic gravitational-wave background from Advanced LIGO and Advanced Virgo's third observing run
2021
We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. Unlike in previous observing runs in the advanced detector era, we include Virgo in the search for the GWB. The results are consistent with uncorrelated noise, and therefore we place upper limits on the strength of the GWB. We find that the dimensionless energy density $\Omega_{\rm GW}\leq 5.8\times 10^{-9}$ at the 95% credible level for a flat (frequency-independent) GWB, using a prior which is uniform in the log of the strength of the GWB, with 99% of the sensitivity comi…
Liberalism, how many divisions?
2022
Liberalism is a very broad political family which, if taken in the broadest sense, brings together authors with diverse positions whose only common point is their attachment to freedom. Therefore, to find one’s way around in this political family, it is essential to establish classification criteria. There are many possibilities: Liberals can be classified by nationality, by period, by preferred field of interest (economic liberalism, political liberalism), etc. This article proposes to classify them following two criteria, the conception of freedom on the one hand, and the utilitarian or jusnaturalist basis of the attachment to freedom on the other. These two criteria generate an operation…
Diez ideas potenciadoras para rendir al máximo en el deporte
2020
El objetivo principal del presente trabajo es el planteamiento de una propuesta práctica de ideas potenciadoras en el deporte. Parte de la base de la Psicología Cognitiva que plantea que existe una interpretación de los acontecimientos que influyen en las emociones y la conducta, y la Psicología Positiva que se centra en lo que se pretende conseguir en lugar de modificar aquello que funciona mal. Se toma como base las teorías cognitivas clásicas y más significativas, junto con diversas estrategias cognitivo-conductuales para aplicar conjuntamente a la implementación de estas ideas en el entorno deportivo. Este tipo de herramientas aplicadas son cada vez más necesarias para profesionales de …
Mental Fatigue Effects on the Produced Perception of Effort and Its Impact on Subsequent Physical Performances.
2022
The purpose of this study was to investigate the relationship between mental fatigue induced by a demanding cognitive task and impaired physical performance in endurance due to a higher perception of effort. A total of 12 healthy adults and volunteers, who had previously practiced endurance activities for 4 to 8 h per week, performed a one-hour cognitive task involving either the process of response inhibition (Stroop task) or not (visualization of a documentary as control task), then 20 min of pedaling on a cycle ergometer at a constant perception of effort while cardio-respiratory and neuromuscular functions were measured. The Stroop task induces subjective feelings of mental fatigue (vig…
A Non-Local Mode-I Cohesive Model for Ascending Thoracic Aorta Dissections (ATAD)
2018
This paper presents a non-local interface mechanical model to describe aortic dissection. In this regard, the mode-I debonding problem based on a cohesive zone modeling is endowed with non-local terms to include long-range interactions that are present in multi-layered biological tissue. Such non-local effects are related to the collagen fibers that transmit forces between non-adjacent elements. Numerical simulations are provided with different values of the non-local parameters in order to show the effect of the non-locality during the debonding processes.
Emotions, stratégies politiques et engagement citoyen
2022
Longtemps décriées pour leur manque de rationalité, les émotions sont pourtant omniprésentes dans les débats politiques et sociétaux actuels. Alors que la sphère publique contemporaine est traversée par des clivages profonds, comment rendre compte des articulations entre émotions collectives, mobilisations politiques et participation citoyenne ? Quels sont les contextes politiques et culturels qui favorisent l'expression des émotions ? Quelle est l'influence des outils numériques dans la formation de communautés émotionnelles et dans l'émergence de nouvelles formes de contestation ? De quelle façon les stratégies d'action des collectifs citoyens intègrent-elles les émotions pour convaincre …
Experimental Evaluation on Narrow Band Power Line Communication in Medium and Low Voltage Smart Grids
2013
The aim of this work is to perform a feasibility study on the power line communication for the development of a new generation of interface devices (IDs) for smart grid and energy storage applications. More in detail, this paper deals with one of the most important issues on this topic, which is the communication system. Among the existing communication technologies, the study is focused on power line communications (PLCs). After an analysis of the state of the art in the field, the main aspects are analyzed, concerning the open issues on the use of PLCs, especially for medium voltage (MV) and low voltage (LV) systems. In this work the use of PLC in MV-LV networks is investigated, by means …
