Labeled Calculi and Finite-Valued Logics

A general class of labeled sequent calculi is investigated, and necessary and sufficient conditions are given for when such a calculus is sound and complete for a finite-valued logic if the labels are interpreted as sets of truth values (sets-as-signs). Furthermore, it is shown that any finite-valued logic can be given an axiomatization by such a labeled calculus using arbitrary "systems of signs," i.e., of sets of truth values, as labels. The number of labels needed is logarithmic in the number of truth values, and it is shown that this bound is tight.     

Disinhibition of return: Unnecessary and unlikely

Recently, from data obtained with a temporal order judgment (TOJ) task, Gibson and Egeth (1994) concluded that inhibition of return (IOR; a response time effect that reveals slower responding to targets at previously cued versus uncued locations) reflects impaired perceptual processing. By replotting their data, we demonstrate that the perception of temporal order is influenced only by the facilitatory effect of a cue at short stimulus onset asynchronies (SOAs) and is unaffected by IOR at long SO As. The target paper proposed that, when extra stimuli are presented at task-relevant locations (i.e., in the TOJ task), IOR is prevented by a hypothetical process that is known as disinhibition of return (DOR). We argue that the assumptions that IOR affects perceptual processing and that DOR exists are unnecessary, as a more parsimonious response-based interpretation of IOR is consistent with their data. Further, we summarize recent results and present new data that demonstrate that DOR is unlikely.     

Amnestic episodes. (Isolated episodes of confusion with amnesia, amnesic ictus, transient global amnesia)]

The author, by giving an outline of one particular case as well as a survey of the relevant literature on transient global amnesia, describes the characteristic clinical picture that is characterized by a sudden loss of what is known as the short-time memory, which usually lasts for several hours, as well as by retrograde amnesia which sometimes dates back to many years. The condition gradually fades away within a few hours or during a night's sleep, and what remains is lack or loss of memory for the episodic period or sometimes retrograde amnesia. Relapses were not observed in the majority of patients. The disease usually develops in people in their sixth to eighth decades of life. The cause of the disease is not yet fully understood. Accordingly, it is justified to use such terms as autochthonous or cryptogenic amnestic episodes. The disease is also discussed from a differential diagnosis point of view.     

Constructing Gender Incommensurability in Competitive Sport: Sex/Gender Testing and the New Regulations on Female Hyperandrogenism

The segregation of the sexes in sport still seems to be regarded as a matter of course. In contrast to other performance classes, e.g., age and weight, which are constructed on the grounds of directly relevant performance features, in the case of gender it is dealt with the merely statistical factor that women on average perform less well than men. And yet unlike weight or age classes, which can be interchanged if the required performances are provided, the segregation between the sexes in many types of sport seems to be quite impermeable. Contrary to popular beliefs women were not excluded from the beginning of modern sport. Hence, the meaning of gender differences varies in the course of time and in types of sport. Thus, this paper firstly gives a short summary of the different relevance of gender differences in high performance competitions of various types of sport. Then the historical construction of gender as central dimension in modern sport will be illustrated by using the example of soccer. Here in this paper, the elaborate processes of reproducing this incommensurability between women and men in sport is the main focus: At first big sport organisations tried to exclude women whose performances were well above the expectations by establishing so called “Gender verifications” which suspected them of fraud. Although it became certain that there is no clear differentiation between the sexes, gender segregation was not abolished. Instead new regulations have been invented to treat and “normalise” people who are difficult to categorise, e.g., transsexuals and women with Hyperandrogenism, in order to subsume them into the existent gender categories. So finally, gender segregation in sport seems to be just another example for Goffman’s institutional reflexivity: While the separation of the competitions are said to be a natural consequence of the differences between men and women, it actually is just a tool to create those differences.     

Professional Experience and Referencing Context Explain Variance in Use of Spatial Frames of Reference

The location of objects in relation to other objects can be perceived of and communicated in different ways. Assuming that variance in spatial Frame of Reference (FoR) use may be explained by practical professional requirements, we reasoned that medical professionals may increasingly use the intrinsic FoR which because of its observer‐independence is less prone to misunderstandings than relative FoRs. We compared FoR‐use of beginner and advanced medical students (n = 142) to that of law students (n = 191) using 40 ambiguous referencing tasks. We found that medical students applied the intrinsic FoR more frequently than law students in a medical yet not in a generic context. Beginners did not differ from advanced students. Within contexts, individuals were highly consistent in their FoR‐use. Investigation of latencies indicates that processing of the intrinsic FoR becomes easier with practice. Theoretical and practical implications are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Emotion recognition in children with Fetal Alcohol Spectrum Disorders

There is a limited amount of research that examines social-emotional functioning in children with Fetal Alcohol Spectrum Disorder (FASD), and the majority of it relies on parent and teacher reports of social impairments. Because these provide broad measures of social function, they fail to elucidate the underlying specific skills with which this group of children has difficulty. The current study examines emotion-recognition abilities in children with FASD, as it plays a central role in social interaction. Participants were 22 children with diagnosed FASD (ages 8–14), and age- and gender-matched typically developing controls. Tasks included measures of emotion recognition from three nonlinguistic modalities: facial expressions, emotional tone of voice, and body positioning and movement. Participant’s parents completed measures of adaptive and behavioral function that were related to children’s performance on aspects of emotion recognition. Overall, the results show that children with FASD have more difficulties with emotion recognition than typically developing age-matched peers, but these difficulties may not be clinically significant (e.g., smaller effect size) or may be specific to the age of the individual exhibiting the emotion (i.e., child vs. adult). These results are discussed in the context of previous studies.
