Implicational Paradoxes and the Meaning of Logical Constants

I discuss paradoxes of implication in the setting of a proof-conditional theory of meaning for logical constants. I argue that a proper logic of implication should be not only relevant, but also constructive and nonmonotonic. This leads me to select as a plausible candidate LL, a fragment of linear logic that differs from R in that it rejects both contraction and distribution.     

Trauma,perversion and marital bond

Abstract

The purpose of this article is to study in the clinic the incidence of so-called perverse phenomena in relationships, in order to find out when these phenomena depend on a perverse organization and when they are only a kind of erotic game between the couple, in both hetero- and homosexual aspects. The first difficulty was to find a definition of “perversion” shared by the authors who have carried out research on the subject and consequently to determine what characterizes a perverse marital bond. In contrast to neurosis, which can be defined by the use of the repression mechanism, the mechanism of disavowal is not exclusive for perversion since it can be found even in other psychical arrangements. Is it, then, a structure or a psychological organization? It is also considered to be a “truth” in psychoanalysis that the pervert cannot be analyzed. But is it the pervert who cannot be analyzed, or is it the analyst who cannot bear listening to him? Do the theoretical references of the analyst not give sufficient theoretical support to maintain his listening? This paper presents the hypothesis that perversion is an attempt – always a frustrated one, and for this reason indefinitely repeated – to elaborate a trauma in which the pervert, identified with the traumatic agent, touches a point equally traumatic for his partner, turning the partner into an object of enjoyment. This arrangement allows the pervert, at least in his imagination, to leave the suffered trauma behind, adopting towards the object a position of activity and domination. Identifying with the aggressor, he leaves his partner paralyzed in the traumatic point, a situation that he knows all too well.

dos Reis Filho JT, et al Trauma, Perversion und eheliche Bande

Der Artikel untersucht klinische Fällen von sogenannter Perversion in Beziehungen, mit dem Ziel herauszufinden, wann es sich um eine perverse Organisation und wann es sich lediglich um eine spezielle Art von erotischem Spiel zwischen dem Paar handelt, dies sowohl in hetero- wie in homosexuellen Beziehungen. Die erste Schwierigkeit war, eine für alle Autoren akzeptable Definition von Perversion zu finden. Alle hatten Erfahrung in Forschung in diesem Gebiet und mussten sich auf Vorstellungen einigen, wodurch eine perverse eheliche Beziehung gekennzeichnet ist. Im Gegensatz zur Neurose, gekennzeichnet ausschliesslich von Verdrängungsmechanismen, kommt Ablehnung nicht ausschliesslich bei der Perversion vor sondern auch bei anderen psychischen Strukturen. Ist Perversion demnach eine psychische Struktur oder eine psychologische Organisation? Es wird auch als erwiesen betrachtet, dass ein Perverser nicht analysiert werden kann. Aber, ist es wirklich der Perverse, der nicht analysiert werden kann? Ist es nicht vielleicht der Analytiker, der es nicht ertragen kann, dem Perversen zuzuhören? Gibt der theoretische analytische Hintergrund des Analytikers ihm möglicherweise nicht genug Unterstützung, um das Zuhören aufrechterhalten zu können? Dieser Aufsatz vertritt die Hypothese, dass die Perversion ein unaufhörlich wiederholter, immer misslingender Versuch ist, ein Trauma aufzuarbeiten. Der Perverse ist identifiziert mit dem Täter im damaligen Trauma. Er trifft einen traumatisierten Punkt beim Partner und macht aus ihm ein Objekt seiner Lusterfüllung. Dieses Arrangement erlaubt dem Perversen-wenigstens in seiner Phantasie – das von ihm erlittene Trauma hinter sich zu lassen, indem er gegenüber dem Objekt eine Position der Aktivität und Dominanz einnimmt. Identifiziert mit dem Aggressor belässt er seinen Partner gelähmt am traumatischen Punkt-eine Situation, die er nur allzu gut an sich selbst kennt.

dos Reis Filho JT et al. Trauma, perversión y el vínculo marital

El propósito del presente trabajo es estudiar en la clínica la incidencia de los cada vez más llamados fenómenos perversos en las relaciones, para descubrir cuando este fenómeno depende de una organización perversa y cuando se trata de un tipo de juego erótico en las parejas, tanto en sus aspectos homosexuales como heterosexuales. La primera dificultad fue encontrar una definición de perversión compartida por los autores estudiosos de este tema y consecuentemente determinar las características de un vínculo marital perverso. En contraste con la neurosis que puede ser definida por el uso del mecanismo de la represión, el mecanismo de la negación no es característico de la perversión únicamente sino que se puede también encontrar en otras organizaciones psíquicas. ¿Se trata entonces de una estructura o de una organización psicológica? Se considera también que en psicoanálisis, es cierto que se trata al perverso como inanalizable. Bueno, ¿es el perverso el que no es analizable o es el psicoanalista que no puede soportar escucharlo? Acaso las referencias teóricas del analista no ofrecen suficientes soportes teóricos para mantener la escucha? Este trabajo presenta la hipótesis de que la perversión es un intento – siempre frustrado, y por lo mismo indefinidamente repetido- para elaborar un trauma en el que el perverso está identificado con el agente traumático, tocando un punto igualmente traumático en su pareja, convirtiendo a su pareja en objeto de su disfrute. Este arreglo permite al perverso, al menos en su imaginación, dejar atrás el trauma sufrido, adoptando con su objeto una posición de actividad y dominación. Identificándose con el agresor, deja a su pareja paralizada en el punto traumático, situación que el perverso sabe muy bien.     

Perceived sexual self-control and condom use with primary and casual sex partners: age and relationship agreement differences in a Portuguese sample

Abstract

Objective: Consistent condom use is still not ideal. Research showed that perceived sexual self-control is associated with greater likelihood of using condoms. However, this association seems to vary according to age and relationship agreement (i.e. non-consensual non-monogamy, NCNM vs. consensual non-monogamy, CNM).

Design: Cross-sectional study with 307 heterosexual users of a dating web site for romantically involved individuals (81.8% men; M_age = 42.24, SD?=?9.65, range: 23–76 years). All individuals were in a romantic relationship (M_length = 13.47 years, SD?=?9.39).

Measures: Demographic information, perceived sexual self-control, condom use frequency (casual sex partners; primary partner in the last 3 months) and relationship agreement.

Results: Independently of relationship agreement, perceived sexual self-control was positively associated with condom use frequency with casual sex partners among younger and middle age participants, but not older ones (>49 years). Regarding the primary partner, a similar pattern emerged for CNM participants. In contrast, no significant association between perceived sexual self-control and condom use frequency with the primary partner emerged for NCNM individuals, regardless of age.

Conclusion: Our findings can inform evidence-based strategies to promote consistent condom use as an effective behaviour to prevent sexually transmitted infections, especially among older and NCNM individuals.     

Buying a passport to heaven: Usury,restitution, and the merchants of medieval Genoa

Historians have argued that the ecclesiastic ban on loans at interest delayed the development of capital markets in the middle ages, and have supported this by pointing to well-documented cases of restitutions of usurious gains by famous moneylenders. Strictly, however, such evidence does not prove that usury laws affected lending, because donations by rich bankers may reflect other motivations. If usury laws had an impact, we have to exclude the Medicis or the Fuggers from the sample, and look for it among the small moneylenders of medieval Europe. Data from late medieval Genoa show that donations by merchants were no greater than those of the population at large once personal wealth is accounted for. However, among merchants the value of pious bequests correlates more closely with mercantile activity than personal wealth, a finding that supports the view that usury laws created an effective constraint on medieval capital markets.     

Picture‐IAT versus Word‐IAT: level of stimulus representation influences on the IAT

The Implicit Association Test is a paradigm designed to assess individual differences in implicit cognition. The goal of this report was to examine the reasons for discrepant effect magnitudes obtained with two presumably interchangeable versions: Picture‐IAT (P‐IAT) and Word‐IAT (W‐IAT). We show that this discrepancy is due to the relation between stimuli and referent category: the level of representation (LR) at which a stimulus represents an intended category. Experiment 1 replicates the discrepancies found in previous research. Experiments 2–4 show that increasing the LR of stimuli increases the IAT effect. LR affects the magnitude of the IAT effect even when modality and other features of the stimuli are kept constant. The utility of LR for future investigations examining the IAT paradigm is discussed.

Time processing in children with Tourette’s syndrome

Background

Tourette syndrome (TS) is characterized by dysfunctional connectivity between prefrontal cortex and sub-cortical structures, and altered meso-cortical and/or meso-striatal dopamine release. Since time processing is also regulated by fronto-striatal circuits and modulated by dopaminergic transmission, we hypothesized that time processing is abnormal in TS.

Methods

We compared time processing abilities between nine children with TS-only (i.e. without major psychiatric comorbidities) and 10 age-matched healthy children, employing a time reproduction task in which subjects actively reproduce different temporal intervals, and a time comparison task in which subjects judge whether a test interval is longer or shorter than a reference interval. IQ, sustained and divided attention, and working memory were assessed in both groups using the Leiter International Performance Scale-Revised, and the Digit Span sub-test of the WISC-R.

Results

Children with TS-only reproduced in an overestimated fashion over-second, but not sub-second, time intervals. The precision of over-second intervals reproduction correlated with tic severity, in that the lower the tic severity, the closer the reproduction of over-second time intervals to their real duration. Time reproduction performance did not significantly correlate with IQ, attention and working memory measures in both groups. No differences between groups were documented in the time comparison task.

Conclusions

The improvement of time processing in children with TS-only seems specific for the over-second range of intervals, consistent with an enhancement in the ‘cognitively controlled’ timing system, which mainly processes longer duration intervals, and depends upon dysfunctional connectivity between the basal ganglia and the dorso-lateral prefrontal cortex. The absence of between-group differences on time comparison, moreover, suggests that TS patients manifest a selective improvement of ‘motor’ timing abilities, rather than of perceptual time abilities. Our data also support an enhancement of cognitive control processes in TS children, probably facilitated by effortful tic suppression.     

Burden, depression, and anxiety in caregivers of people with amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disease caused by the degeneration of motor neurons. The burden for ALS caregivers is quite high. There are still few studies that have investigated the emotional impact of ALS care. We conducted a cross-sectional study among 40 ALS caregivers, assessing general worries, burden of care, depression, anxiety, perception of social support, and patients' severity of disease. Caregiver burden, depression, and anxiety were positively related with each other, and all these variables had a negative relation with social support. Patient's loss of physical functions was positively related with caregiver burden, anxiety, and somatic expression of depression. Caregivers expressed worries for their own health conditions. Given these results, we consider the hypothesis of an emotional-somatic impact of ALS care. The implications and limitations are discussed.     

Work Context Support and Portuguese Soldiers’ Well-Being: The Mediating Role of Autonomous Motivation

Using self-determination theory ( Deci & Ryan, 2008 Deci, E. L., & Ryan, R. M. (2008). Self-determination theory: A macrotheory of human motivation, development, and health. Canadian Psychology, 49, 182–185. 10.1037/a0012801[Crossref], [Web of Science ®] , [Google Scholar]) as the theoretical framework, we tested a model for this study that considers soldiers’ perceptions of organizational support and leader–member exchange (LMX), work motivation, and well-being at work. The hypothesized model was tested using a representative sample of 1,045 Portuguese soldiers. Results revealed that autonomous work motivation was significantly related to both contextual factors (organizational support and LMX). In addition, autonomous work motivation was positively related to work engagement and negatively related to burnout, and controlled motivation showed the opposite pattern. More interesting, the results showed that autonomous work motivation as a mechanism that helped to explain the relationship between both contextual factors and workplace well-being. The present results underscore the importance of understanding the mechanisms through which higher work engagement and lower burnout take place, eventually leading to appropriate interventions.
