Abstract. Aims: To discuss and review the latest research related to gambling expansion. Method: We completed a literature review and empirical comparison of peer reviewed findings related to gambling expansion and subsequent gambling-related changes among the population. Results: Although gambling expansion is associated with changes in gambling and gambling-related problems, empirical studies suggest that these effects are mixed and the available literature is limited. For example, the peer review literature suggests that most post-expansion gambling outcomes (i. e., 22 of 34 possible expansion outcomes; 64.7 %) indicate no observable change or a decrease in gambling outcomes, and a minority (i. e., 12 of 34 possible expansion outcomes; 35.3 %) indicate an increase in gambling outcomes. Conclusions: Empirical data related to gambling expansion suggests that its effects are more complex than frequently considered; however, evidence-based intervention might help prepare jurisdictions to deal with potential consequences. Jurisdictions can develop and evaluate responsible gambling programs to try to mitigate the impacts of expanded gambling.

Task Perception

Over the last 30 years, numerical estimation has been largely studied. Recently, Castronovo and Seron (2007) proposed the bi-directional mapping hypothesis in order to account for the finding that dependent on the type of estimation task (perception vs. production of numerosities), reverse patterns of performance are found (i.e., under- and over-estimation, respectively). Here, we further investigated this hypothesis by submitting adult participants to three types of numerical estimation task: (1) a perception task, in which participants had to estimate the numerosity of a non-symbolic collection; (2) a production task, in which participants had to approximately produce the numerosity of a symbolic numerical input; and (3) a reproduction task, in which participants had to reproduce the numerosity of a non-symbolic numerical input. Our results gave further support to the finding that different patterns of performance are found according to the type of estimation task: (1) under-estimation in the perception task; (2) over-estimation in the production task; and (3) accurate estimation in the reproduction task. Moreover, correlation analyses revealed that the more a participant under-estimated in the perception task, the more he/she over-estimated in the production task. We discussed these empirical data by showing how they can be accounted by the bi-directional mapping hypothesis ( Castronovo & Seron, 2007 ).

Essential Prerequisite

The article considers proper legislation as an essential prerequisite for actualization of NPOs comparative advantages. Restrictions imposed on NPOs are reasonable if they are compensated by benefits from greater trust. The rigidity of constrains and requirements should be optimized while accounting for peculiarities of a social medium, the state of the nonprofit sector, and the governments readiness to encourage the development of the latter. As empirical data suggests, Russian NPOs being on different stages of maturity need separate legal treatment. In the meanwhile, interests that prevail in the NPOs community are not always conducive to rapid changes.

This article offers economic and sociological theory of trust, embodying the idea of "social capital" by James Coleman. It also analyzes empirical data on personal and institutional trust obtained on the basis of nationwide opinion poll in the project "Comparative studies of trust in different countries during the period of globalization". The problem of trust is considered in the context of the international projects "World Values Survey" and "Trust Barometer" which made it possible to construct a mental world map of personal and institutional trust for various countries. It is shown that Russia has not a low, but a medium level of trust. In the mental world map some patterns were presented that reflect the basic trust as a form of social capital.

This article discusses and raises awareness about the socio-economic plight of indigenous musicians in South Africa. Through a qualitative case study of the Venda musician, Vho-Talelani Andries Ntshengedzeni Mamphodo, dubbed the “Father of mbila music,” the article highlights the fact that the welfare of Black South African artists, particularly indigenous musicians in South Africa, is generally a precarious affair. Their popularity, at the height of their careers, sometimes masks shocking details of exploitation, neglect, and the poverty they are subjected to, which are exposed only after they have died. Empirical data identifies this as a symptom of, among other things, cultural policy and arts management deficiencies in the promotion of indigenous music. The article aims to find ways to redress this unfortunate situation, which is partially a product of general apathy and scant regard that these artists have perennially been subjected to, even by their own governments, as well as some members of their societies. All these factors mentioned are compounded by ignorance on the part of South African artists. Part of the objective of this study was to establish whether the exposition of the Vhavenda musicians is a typical example of all Black South African indigenous musicians and, if this is the case, whether the suggested ways to redress this unfortunate situation could contribute to or play a role in alleviating the plight of such artists in the entire country.

A deixis emocional em português europeu contemporâneo: alguns contributos

This paper is a contribution to the description of the structures that express emotional deixis, in European contemporary Portuguese. The analysis of our empirical data show that, in Portuguese, demonstratives are not the only category that encodes emotional deictic meaning; possessives and first person plural display the same function, in some contexts. It is also discussed the semantic bleaching of the deictic space adverbs cá and lá and it is argued that it can only be described and explained in illocutionary terms, and not in the framework of emotional deixis.
