Impaired Self-Awareness in Pathological Gamblers

Lack of self-awareness of one’s decisions remains an understudied and elusive topic in the addiction literature. The present study aimed at taking a first step towards addressing this difficult subject through the use of a combination of behavioral procedures. Here, we explored the association between a metacognitive process (the ability to reflect and evaluate the awareness of one’s own decision) and poor performance on the Iowa Gambling Task (IGT) in a group of pathological gamblers (PG; n = 30), and in a comparison group (n = 35). This metacognitive process was assessed during the IGT with the post-decision wagering procedure, while a number of potential confounds (i.e., reward/loss sensitivity, dual-tasking) were controlled for. Results showed that: (1) Initial performance enhancement of the control group on IGT occurred without explicit knowledge of the task, thus confirming its implicit character; (2) compared to controls, performance of PG on the IGT failed to increase during the task; (3) taking into account increased reward sensitivity and decreased loss sensitivity as well as poorer dual-tasking in pathological gamblers, PG tended to exhibit a bias in evaluating their own performance on the IGT by maximizing their wagers independently of selecting advantageous decks. Our findings suggest that biased metacognition may affect pathological gamblers, leading to disadvantageous post-decision wagering, which is in turn linked to impaired decision making under ambiguity. Perhaps this deficit reflects the impaired insight and self-awareness that many addicts suffer from, thus providing a novel approach for capturing and measuring this impairment, and for investigating its possible causes.     

Wind farms in rural areas: How far do community benefits from wind farms represent a local economic development opportunity?

Although the large-scale deployment of renewable technologies can bring significant, localised economic and environmental changes, there has been remarkably little empirical investigation of the rural development implications. This paper seeks to redress this through an analysis of the economic development opportunities surrounding wind energy development in rural Wales. The paper concludes that the economic development outcomes to rural areas from wind generation projects to date have been questionable. Increasing the flow of conventional economic benefits to rural economies in terms of incomes and jobs is shown to be difficult because of the nature of the local supply side in remote areas. Partially as a consequence of this, developers of wind farms have come to routinely provide diverse forms of community benefits to ‘affected communities’, but these have yet to evolve into significant tools of economic development. In any case, the flows of revenues from community benefits are dwarfed, in quantitative terms, by the revenue streams that might be channelled to rural areas through a broader community ownership of wind energy projects. However, although a few local successes have been achieved, the scope for realising the returns from community ownership remains low in the Welsh case, with a series of impediments considered. We close the paper by suggesting means through which economic outputs might be improved.     

An institutional approach to research on public procurement of innovation

The role of public procurement as a means to stimulate innovation has been increasingly emphasized during the last few years. The general argument is that, by applying intelligent demand, public agencies can stimulate private sector innovation that will eventually sustain competitive advantage in a global economy. The emphasis on public procurement used as an innovation policy instrument challenges current institutional practices and skills. The article is based on the assumption that the innovation research community could inform this policy discourse, in particular by drawing on institutional theory, but in order to fully utilize this potential, further revision of the research perspectives seen is needed. The article therefore discusses an institutional approach based on three modes: “multilevel institutional analysis”, “endogenous and exogenous institutions” and “institutions as rationalities”, arguing that such an approach would help to increase innovation research quality and policy relevance.     

A two sample ordered alternative test for means and variances

A two sample test of likelihood ratio type is proposed, assuming normal distribution theory, for testing the hypothesis that two samples come from identical normal populations versus the alternative that the populations are normal but vary in mean value and variance with one population having a smaller mean and smaller variance than the other. The small sample and large sample distribution of the proposed statistic are derived assuming normality. Some computations are presented which show the speed of convergence of small sample critical values to their asymptotic counterparts. Comparisons of local power of the proposed test are made with several potential competing tests. Asymptotics for the test statistic are derived when underlying distributions are not necessarily normal.     

The semantic distinction between "risk" and "danger": a linguistic analysis

The analysis combines frame semantic and corpus linguistic approaches in analyzing the role of agency and decision making in the semantics of the words "risk" and "danger" (both nominal and verbal uses). In frame semantics, the meanings of "risk" and of related words, such as "danger," are analyzed against the background of a specific cognitive-semantic structure (a frame) comprising frame elements such as Protagonist, Bad Outcome, Decision, Possession, and Source. Empirical data derive from the British National Corpus (100 million words). Results indicate both similarities and differences in use. First, both "risk" and "danger" are commonly used to represent situations having potential negative consequences as the result of agency. Second, "risk" and "danger," especially their verbal uses (to risk, to endanger), differ in agent-victim structure, i.e., "risk" is used to express that a person affected by an action is also the agent of the action, while "endanger" is used to express that the one affected is not the agent. Third, "risk," but not "danger," tends to be used to represent rational and goal-directed action. The results therefore to some extent confirm the analysis of "risk" and "danger" suggested by German sociologist Niklas Luhmann. As a point of discussion, the present findings arguably have implications for risk communication.
