New Methodological Approaches for Change in Traditional Sectors: The Case of the Portuguese Fisheries Socio-Economic System

This paper summarises the methodological approach and main results of the MARHE project (Employment and Human Resources in the Fisheries Socio-Economic System). This project had as its main aim the search for alternative futures for the fisheries sector in Portugal, with particular attention being paid to the human resources situation and the working and living conditions of the fisheries-dependent populations in the coastal areas. This is a particularly interesting case, since fisheries were once an important activity and they are now in deep recession, even though it is generally recognised that the future utilisation of maritime resources offer an immense potential. As part of the research, a Delphi exercise was implemented involving in two successive stages some of the leading actors and experts dealing with the sector in Portugal. Other initiatives were held in the context of the MARHE project providing direct and indirect inputs to the scenarios and recommendations that were put forward in the sequence of the Delphi exercise. Overall the activities described in the paper contributed to the mobilisation of major actors and to discussions that may have practical implication for the future of the sector, if certain conditions are now met in the follow up to the project.Fisheries; Portugal; human resources; scenarios; labour market

Signatures of Confinement in Axial Gauge QCD

A comparative dynamical study of axial gauge QED and QCD is presented. Elementary excitations associated with particular field configurations are investigated. Gluonic excitations analogous to linearly polarized photons are shown to acquire infinite energy. Suppression of this class of excitations in QCD results from quantization of the chromelectric flux and is interpreted as a dual Meissner effect, i.e. as expulsion from the QCD vacuum of chromo-electric fields which are constant over significant distances. This interpretation is supported by a comparative evaluation of the interaction energy of static charges in the axial gauge representation of QED and QCD.Comment: 22 pages (no figures

Through the eyes of others - The social experiences of people with dementia: A systematic literature review and synthesis

Psychosocial models suggest that the lived experience of dementia is affected by interpersonal factors such as the ways in which others view, talk about, and behave toward the person with dementia. This review aimed to illuminate how informal, everyday interpersonal relationships are experienced by people with dementia within their social contexts. A systematic review of qualitative literature published between 1989 and May 2016 was conducted, utilizing the electronic databases PsycINFO, MEDLINE, and CINAHL-Complete. This was followed by a critical interpretative synthesis to understand how people with dementia perceive the attitudes, views, and reactions of other people toward them, and the subjective impact that these have. Four major themes were derived from the findings of the 23 included studies: being treated as an “other” rather than “one of us”; being treated as “lesser” rather than a full, valued member of society; the impact of others’ responses; and strategies to manage the responses of others. Thus, people with dementia can feel outcast and relegated, or indeed feel included and valued by others. These experiences impact upon emotional and psychological well-being, and are actively interpreted and managed by people with dementia. Experiences such as loss and diminishing identity have previously been understood as a direct result of dementia, with little consideration of interpersonal influences. This review notes that people with dementia actively engage with others, whose responses can foster or undermine social well-being. This dynamic relational aspect may contribute to emerging understandings of social health in dementia

Antitrust and Health Care—Psychologists Entitled to Blue Shield Reimbursement—Virginia Academy of Clinical Psychologists v. Blue Shield of Virginia, 624 F.2d 476 (4th Cir. 1980), cert. denied 450 U.S. 916 (1981)

In Virginia Academy of Clinical Psychologists v. Blue Shield of Virginia, the Fourth Circuit Court of Appeals held that Blue Shield violated section 1 of the Sherman Antitrust Act because Blue Shield refused to pay psychologists who did not bill through physicians. The court held that Blue Shield constituted a conspiracy of individual physicians acting to reduce competition in the delivery of psychotherapeutic services. This holding significantly enhances the ability of psychologists and other licensed health care providers to compete with physicians. This Note discusses Virginia Academy in light of the pertinent antitrust doctrines. It approves the Fourth Circuit\u27s holding and recognition of physician control of Blue Shield. It criticizes, however, the court\u27s failure to label the defendants\u27 conduct a boycott. This Note proposes judicial application of the per se rule rather than the Rule of Reason in cases such as Virginia Academy in order to bring them more in line with classic antitrust doctrine

Gravitational Collapse of a Homogeneous Scalar Field in Deformed Phase Space

We study the gravitational collapse of a homogeneous scalar field, minimally coupled to gravity, in the presence of a particular type of dynamical deformation between the canonical momenta of the scale factor and of the scalar field. In the absence of such a deformation, a class of solutions can be found in the literature [R. Goswami and P. S. Joshi, arXiv:gr-qc/0410144], %\cite{JG04}, whereby a curvature singularity occurs at the collapse end state, which can be either hidden behind a horizon or be visible to external observers. However, when the phase-space is deformed, as implemented herein this paper, we find that the singularity may be either removed or instead, attained faster. More precisely, for negative values of the deformation parameter, we identify the emergence of a negative pressure term, which slows down the collapse so that the singularity is replaced with a bounce. In this respect, the formation of a dynamical horizon can be avoided depending on the suitable choice of the boundary surface of the star. Whereas for positive values, the pressure that originates from the deformation effects assists the collapse toward the singularity formation. In this case, since the collapse speed is unbounded, the condition on the horizon formation is always satisfied and furthermore the dynamical horizon develops earlier than when the phase-space deformations are absent. These results are obtained by means of a thoroughly numerical discussion.Comment: 17 pages, 17 figure
