Divulgación de información responsable en el deporte a través de las páginas web

In recent years, there is a growing consensus on the importance of Corporate Social Responsibility for organisations with the aim of achieving sustainable development. This study aims to analyse the dissemination of information on Corporate Social Responsibility through the websites of Portuguese Liga NOS clubs in the 2017/2018 sport season. The study is descriptive in nature and is based on a qualitative methodology using the content analysis technique. The results show that the degree of information disclosed is low, as revealed by the total disclosure index (26.63%), and that the most disclosed information is social, followed by economic information. However, very little information is disclosed on employee recruitment and environment. _____ En los últimos años, está siendo consensuada cada vez más la importancia en lo que respecta a la Responsabilidad Social Corporativa para las organizaciones con el objetivo de alcanzar un desarrollo sostenible.

Serum peptide reactivities may distinguish neuromyelitis optica subgroups and multiple sclerosis

Objective: To assess in an observational study whether serum peptide antibody reactivities may distinguish aquaporin-4 (AQP4) antibody (Ab)–positive and -negative neuromyelitis optica spectrum disorders (NMOSD) and relapsing-remitting multiple sclerosis (RRMS). Methods: We screened 8,700 peptides that included human and viral antigens of potential relevance for inflammatory demyelinating diseases and random peptides with pooled sera from different patient groups and healthy controls to set up a customized microarray with 700 peptides. With this microarray, we tested sera from 66 patients with AQP4-Ab-positive (n = 16) and AQP4-Ab-negative (n = 19) NMOSD, RRMS (n = 11), and healthy controls (n = 20). Results: Differential peptide reactivities distinguished NMOSD subgroups from RRMS in 80% of patients. However, the 2 NMOSD subgroups were not well-discriminated, although those patients are clearly separated by their antibody reactivities against AQP4 in cell-based assays. Elevated reactivities to myelin and Epstein-Barr virus peptides were present in RRMS and to AQP4 and AQP1 peptides in AQP4-Ab-positive NMOSD. Conclusions: While AQP4-Ab-positive and -negative NMOSD subgroups are not well-discriminated by peptide antibody reactivities, our findings suggest that peptide antibody reactivities may have the potential to distinguish between both NMOSD subgroups and MS. Future studies should thus concentrate on evaluating peptide antibody reactivities for the differentiation of AQP4-Ab-negative NMOSD and MS

Reconstructing institutional complexity in practice: A relational model of institutional work and complexity

This article develops a relational model of institutional work and complexity. This model advances current institutional debates on institutional complexity and institutional work in three ways. First, it provides a relational and dynamic perspective on institutional complexity by explaining how constellations of logics - and their degree of internal contradiction - are constructed rather than given. Second, it refines our current understanding of agency, intentionality and effort in institutional work by demonstrating how different dimensions of agency interact dynamically in the institutional work of reconstructing institutional complexity. Third, it situates institutional work in the everyday practice of individuals coping with the institutional complexities of their work. In doing so, it reconnects the construction of institutionally complex settings to the actions and interactions of the individuals who inhabit them

MRI phase changes in multiple sclerosis vs neuromyelitis optica lesions at 7T

OBJECTIVE: To characterize paramagnetic MRI phase signal abnormalities in neuromyelitis optica spectrum disorder (NMOSD) vs multiple sclerosis (MS) lesions in a cross-sectional study. METHODS: Ten patients with NMOSD and 10 patients with relapsing-remitting MS underwent 7-tesla brain MRI including supratentorial T2*-weighted imaging and supratentorial susceptibility weighted imaging. Next, we analyzed intra- and perilesional paramagnetic phase changes on susceptibility weighted imaging filtered magnetic resonance phase images. RESULTS: We frequently observed paramagnetic rim-like (75 of 232 lesions, 32%) or nodular (32 of 232 lesions, 14%) phase changes in MS lesions, but only rarely in NMOSD lesions (rim-like phase changes: 2 of 112 lesions, 2%, p < 0.001; nodular phase changes: 2 of 112 lesions, 2%, p < 0.001). CONCLUSIONS: Rim-like or nodular paramagnetic MRI phase changes are characteristic for MS lesions and not frequently detectable in NMOSD. Future prospective studies should ask whether these imaging findings can be used as a biomarker to distinguish between NMOSD- and MS-related brain lesions

Divulgação de informação sobre responsabilidade social no desporto através das páginas web

Objetivos – O objetivo deste estudo é analizar a divulgação de informação sobre Responsabilidade Social Corporativa (RSC) através dos websites dos clubes portugueses da Liga NOS na época desportiva de 2017/2018, na qual participavam 18 equipas. Referencial Teórico – Para proceder à concretização do estudo foi necessário a criação de um modelo que estivesse de acordo com a realidade desportiva, mais concretamente em conformidade com os Clubes da Liga NOS. Desta forma foi necessário adaptar para este fim um modelo já existente para medir o nível de divulgação de informação sobre RSC nos Municípios apresentado por um conjunto de autores que desenvolveram diversos estudos como: Gandía e Archidona (2008), Jorge et al (2011), Navarro et al (2010), Joseph e Taplin (2011), Moneva e Martín (2012) e Nevado et al (2013). Metodologia – O estudo é de carácter exploratório e baseado numa metodologia do tipo qualitativo, onde a recolha e análise bibliográfica e documental recaem sobre os estudos já existentes sobre a temática da RS associada ao contexto desportivo e na recolha de informação através das páginas web. Conclusões/Resultados – Os resultados mostram que foi possível verificar que na grande maioria dos clubes são muito escassas as informações divulgadas sobre RSC. Implicações da investigação – A adaptação a partir de um modelo existente de divulgação de Informação sobre RSC nas páginas web dos Municípios pode ser entendido como uma limitação, uma vez que este pode não incluir em todos os itens que o compõem toda a informação adjacente à RSC dos clubes estudados. Originalidade - Considerando a importância atual do acesso à informação através de ferramentas digitais este trabalho, aplicado pela primeira vez a organizações desportivas contribui para uma melhor compreensão e diagnóstico sobre a divulgação de informação sobre RSC através das websites.info:eu-repo/semantics/publishedVersio

Neuromyelitis optica does not impact periventricular venous density versus healthy controls: a 7.0 Tesla MRI clinical study

Objective: To quantify the periventricular venous density in neuromyelitis optica spectrum disease (NMOSD) in comparison to that in patients with multiple sclerosis (MS) and healthy control subjects. Materials and methods: Sixteen patients with NMOSD, 16 patients with MS and 16 healthy control subjects underwent 7.0-Tesla (7T) MRI. The imaging protocol included T2*-weighted (T2*w) fast low angle-shot (FLASH) and fluid-attenuated inversion recovery (FLAIR) sequences. The periventricular venous area (PVA) was manually determined by a blinded investigator in order to estimate the periventricular venous density in a region of interest-based approach. Results: No significant differences in periventricular venous density indicated by PVA were detectable in NMOSD versus healthy controls (p = 0.226). In contrast, PVA was significantly reduced in MS patients compared to healthy controls (p = 0.013). Conclusion: Unlike patients with MS, those suffering from NMOSD did not show reduced venous visibility. This finding may underscore primary and secondary pathophysiological differences between these two distinct diseases of the central nervous system

On the Second Law of thermodynamics and the piston problem

The piston problem is investigated in the case where the length of the cylinder is infinite (on both sides) and the ratio $m/M$ is a very small parameter, where $m$ is the mass of one particle of the gaz and $M$ is the mass of the piston. Introducing initial conditions such that the stochastic motion of the piston remains in the average at the origin (no drift), it is shown that the time evolution of the fluids, analytically derived from Liouville equation, agrees with the Second Law of thermodynamics. We thus have a non equilibrium microscopical model whose evolution can be explicitly shown to obey the two laws of thermodynamics.Comment: 29 pages, 9 figures submitted to Journal of Statistical Physics (2003
