The umbrella-term ‘executive functions’ includes various domain-general, goal-directed cognitive abilities responsible for behavioral self-regulation. The influential unity and diversity model of EF posits the existence of three correlated yet separable executive domains: inhibition, shifting and updating. These domains may be influenced by factors such as socioeconomic status and culture, possibly due to the way EF tasks are devised and to biased choice of stimuli, focusing on first-world testees. Here, we propose a FREE test battery that includes two open-access tasks for (...) each of the three abovementioned executive domains to allow latent variables to be obtained. The tasks were selected from those that have been shown to be representative of each domain, that are not copyrighted and do not require special hardware/software to be administered. These tasks were adapted for use in populations with varying SES/schooling levels by simplifying tasks/instructions and using easily recognized stimuli such as pictures. Items are answered verbally and tasks are self-paced to minimize interference from individual differences in psychomotor and perceptual speed, to better isolate executive from other cognitive abilities. We tested these tasks on 146 early adolescents of both sexes and varying SES, because this is the age group in which the executive domains of interest become distinguishable and in order to confirm that SES effects were minimized. Performance was determined by Rate Correct Scores, which consider speed-accuracy trade-offs. Scores were sensitive to the expected improvement in performance with age and rarely/inconsistently affected by sex and SES, as expected, with no floor or ceiling effects, or skewed distribution, thus suggesting their adequacy for diverse populations in these respects. Using structural equation modeling, evidence based on internal structure was obtained by replicating the three correlated-factor solution proposed by the authors of the model. We conclude that the FREE test battery, which is open access and described in detail, holds promise as a tool for research that can be adapted for a wide range of populations, as well as altered and/or complemented in coming studies.

This study examines BDI logics in the context of Gabbay's fibring semantics. We show that dovetailing can be adopted as a semantic methodology to combine BDI logics. We develop a set of interaction axioms that can capture static as well as dynamic aspects of the mental states in BDI systems, using Catach's incestual schema G^[a, b, c, d]. Further we exemplify the constraints required on fibring function to capture the semantics of interactions among modalities. The advantages of having a fibred (...) approach is discussed in the final section. (shrink)

In this paper, I argue that scholars such as John Braithwaite and Lode Walgrave rely on fictions when presenting their utopian vision of restorative justice. Three claims in particular are shown to be fictitious. Proponents of restorative justice maintain, first, that the offender and the victim voluntarily attend the restorative conference. Second, that the restorative conference enables the offender and the victim to take on active responsibility. Third, that the reparatory tasks on which the parties agree should not be understood (...) in terms of the intentional infliction of harm. These fictions, so I argue, are not merely a mistake, but instead serve an important function: the various parties need to believe that they adequately capture the reality of the restorative conference as they are more likely to acquiesce if they believe the fictions to be true. I conclude that the fictions are the driving force within the restorative endeavour. (shrink)

Attention has been drawn, particularly since Kant, to propositions which can not have negative instances. They used to be called a priori, axioms, first principles. Today, they are usually called postulates—C. I. Lewis uses both the old and new terminology—because there is a growing recognition of the fact that at least some of them are not “necessary” in the traditional sense. Kant placed a limitation on the apriorism of the continental rationalists. Current epistemologists and logicians have outstripped Kant in the (...) direction signalled by him. Both he and they, however, concur in the opinion that apriori propositions are subject to negation of a sort. The Kantian dinge-an-sich, though they can not contradict these propositions by being negative instances of them, do nevertheless stand to them in the relation of insubordination, thereby exerting on them a “negative action” of a sort. And, according to current views, there are instances which, though they fall outside the range of significance of a proposition or system and hence can not contradict it, do nevertheless tend to bring about a revision of it by a negative action of some sort. The purpose of this brief essay is to coin a convenient name for such instances and to describe certain properties of their peculiar negative action. (shrink)

Background: The Declaration of Helsinki prohibits the publication of articles that do not meet defined ethical standards for reporting of research ethics board approval and informed consent. Despite this prohibition and a call to highlight the deficiency for the reader, articles with potential ethical shortcomings continue to be published.Objective: To determine what proportion of articles in major medical journals lack statements confirming REB approval and informed consent, and whether accompanying commentary alerts readers to this deficiency.Design: Retrospective, observational study.Setting: Online review (...) of five major medical journals.Population: All clinical research articles published online between 1 January 2005 and 31 December 2006 in the BMJ, Lancet, Annals of Internal Medicine, JAMA and the New England Journal of Medicine.Measurements: Statement of REB approval and informed consent.Results: Of 1780 articles reviewed, 1133 met inclusion criteria , 36 articles lacked a statement of REB approval, 62 lacked disclosure of informed consent and 15 articles lacked both. Articles that did not state REB approval were associated with not stating informed consent . There were no editorial comments to alert readers to the lack of either REB approval or informed consent statements associated with any of the deficient articles.Conclusions: Articles that lack explicit statements of REB approval and informed consent are infrequent but continue to be published in major medical journals without editorial statements to alert the reader to this deficiency.
