Neuroplastic Changes Following Social Cognition Training in Schizophrenia: A Systematic Review

Social cognitive impairment is a key feature of schizophrenia and social cognition training (SCT) is a promising tool to address these deficits. Neurobiological dysfunction in schizophrenia has been widely researched, but neuronal changes induced by SCT have been scarcely explored. This review aims to assess the neuroplastic effects of SCT in patients with schizophrenia spectrum disorders. PubMed and Web of Science databases were searched for clinical trials testing the effects of SCT in functional and structural brain measurements of adult patients with schizophrenia or schizoaffective disorders. A total of 11 studies were included: five used fMRI, two used EEG and ERP, one used ERP only, two used MEG and one study used MRI. Data extracting and processing regarding sociodemographic and clinical variables, intervention characteristics, neuroimaging procedures, neuroplastic findings, effect sizes and study quality criteria was completed by two raters. Results indicate a wide range of structural and functional changes in numerous regions and circuits of the social brain, including early perceptual areas, the limbic system and prefrontal regions. Despite the small number of trials currently available, evidence suggests that SCT is associated with neuroplastic changes in the social brain and concomitant improvements in social cognitive performance. There is a lack of extensive knowledge about the neural mechanisms that underlie social cognitive enhancement after treatment, but the reported findings may shed light on the neural substrates of social cognitive impairment in schizophrenia and how improved treatment procedures can be developed and applied.     

‘For Fun’: (De) Humanizing Gisberta—The Violence of Binary Gender Social Representation

In 2006, Gisberta Salce Júnior died inside of a pit, in an abandoned building, after being tortured for 3 days by a group of teenagers, in Porto, Portugal. Gisberta was a transgender woman who had moved to Portugal from Brazil in the 1980’s. In this paper, we explore the media coverage of her death as an illustrative case of existing social representations of gender, resulting in two main findings: that even those who are seen as communities of support and recognition perpetuate discourses of gender binary norms, and that the only apparent possibility to humanize and transcend these norms is materialized in artistic performance and production, which allows for a more emotional connection to the ‘subject’ as a human individual rather than a mere transgression. The analysis of articles about Gisberta revealed that there is a very strong social representation of gender as a binary, consisting rigidly of female and male poles. As such, the social representation of those individuals who transgress this binary, embodying alternative performances of gender, as was the case with Gisberta, is reduced to their sexuality, their embodiment of something other than the gender binary. Different perspectives were identified: media, the courtroom, the teenagers, LGTB activists and the arts. Through this analysis and division, it was possible to conclude that these binary norms are embedded to the extent that they permeate even the discourses of those who tend to speak for trans people, in such a way that it seems almost impossible to escape them, with one powerful exception: that of artistic expression, which seems to be the only topos from which true recognition is achieved. This case is an extreme example of the necessity to transcend gender norms and allow for recognition of individuals as such.     

Aggressive Hook Ups: Modeling Aggressive Casual Sex on BDSM for Moral Permissibility

Aggressive techniques within casual sex encounters, such as taking sexual liberties without permission or ignoring rejection, can, perhaps unintentionally, complicate consent. Passive recipients may acquiesce out of fear, which aggressors may not realize. Some philosophers argue that social norms are sufficiently well known to make this misunderstanding unlikely. However, the chance of aggression leading to non-consensual sex, even if not great, is high enough that aggressors should work diligently to avoid this potentially grave result. I consider how this problem plays out in the common mating ritual of hooking up. I argue that aggressive hook ups can only be permissible if they are modeled on BDSM encounters: the participants must obtain prior consent and prepare safe words for voiding that consent during the hook up. While this solution removes the spontaneity of aggressive sex, I argue that spontaneously aggressive hook ups with strangers cannot be permissible.     

A Decision Support System for Prioritizing Investments in an Energy Efficiency Program in Favelas in the City of Rio de Janeiro

This study proposes an integrated qualitative and quantitative assessment of expert opinions aiming at ranking a set of five shantytowns (favelas) located in the city of Rio de Janeiro. These communities are candidates for investments in an energy efficiency program implemented by the local electric utility company. The city, state, and federal governments want to eliminate domination of these areas by organized criminal gangs and present the city as a peaceful metropolis while hosting two big sports events: the soccer World Cup in 2014 and the Olympic Games in 2016. In recent years, some favelas were chosen to be prototypes for an ambitious project to reshape Rio de Janeiro. This involves first sending in special tactics police to drive drug gangs out, then installing the Pacifying Police Unit in the favela. Once security has been established, it is possible to improve general living conditions in these areas, including by providing public services such as health clinics, formal electricity connections and cable television. The core of the energy efficiency program was to convert informal customers to formal ones, because such communities were responsible for approximately 40% of the commercial losses (stolen energy) in the city. The model specification presented in this paper was set up with ten relevant criteria for decision making, identified through an in‐depth interview with the decision maker. The relative importance of the criteria and the performance of each favela regarding each criterion were measured by the Simos method. The preferences resulting from this method were translated into a nine‐point scale. The imprecision of subjective judgment was partially compensated by using a fuzzy analytical hierarchy process. Some criteria were ordinal, such as ‘Fair Relationship with the Community’ and ‘Complexity to Rebuild the Distribution Lines’, whereas other were cardinal, like ‘Percentage of Clients in Default’ and ‘Commercial Loss Due to Energy Theft’. At the end, the model was efficient in ranking the five favelas, therefore contributing to a rational and transparent approach for capital investment in social projects.

Subjective perception of health in elderly inpatients

There is evidence that subjective health is an important variable in general health outcomes. It can be an indicator of the individual's overall health status, creating a reliable and valid estimate about health. Quality of life (QoL) assessment can be associated with the individuals' subjective assessment of their own health status. The aim of the present study was to investigate variables associated with subjective perception of health in older inpatients. Ninety elderly inpatients over 60 years old were interviewed. The perception of health assessment (healthy/unhealthy) allocated elders in either of two groups. All the elders answered sociodemographic questions, the WHOQOL-100 and the Beck Depression Inventory (BDI). Comparing the group that considered themselves unhealthy to the other group, the former showed a tendency of worse QoL assessments in five out of six domains investigated. Significant differences were found for the physical and level of independence domains, as well as overall QoL. There was a significant association between health perception and lower intensity of depressive symptoms, as well as better QoL perception in the level of independence domain. This study shows the existence of an association between depressive symptoms and health assessment. It also suggests that the independence dimension is important in the elders' perception of their health status. These findings can help identify cause-effect relations between variables in aging studies involving health indicators and bring new intervention proposals for the elderly.     

Phase-oscillator computations as neural models of stimulus–response conditioning and response selection

The activity of collections of synchronizing neurons can be represented by weakly coupled nonlinear phase oscillators satisfying Kuramoto’s equations. In this article, we build such neural-oscillator models, partly based on neurophysiological evidence, to represent approximately the learning behavior predicted and confirmed in three experiments by well-known stochastic learning models of behavioral stimulus–response theory. We use three Kuramoto oscillators to model a continuum of responses, and we provide detailed numerical simulations and analysis of the three-oscillator Kuramoto problem, including an analysis of the stability points for different coupling conditions. We show that the oscillator simulation data are well-matched to the behavioral data of the three experiments.     

Perseveration in congenitally blind children: Effects of luminous and acoustic targets on a modified A-not-B task

The purpose of this study was to determine whether or not blind children perseverate during a modified Piagetian A-not-B reaching task, with conditions that employ luminous AB targets and acoustic AB targets. Ten congenitally blind children, ages 1–4 years, with residual vision for light, took part in this study. Behavioral and kinematic data were computed for participants’ reaches, performed in six A trials and in two B trials, in both stimulus conditions. All of the children perseverated in the luminous condition, and none of them perseverated in the condition using acoustic targets. The children tilted their heads in the direction of the target as they reached towards it. However, this coupling action (head-reaching) occurred predominantly in the A trials in the acoustic condition. In the luminous condition, in contrast to the acoustic condition, the children took longer times to initiate the reaching movement. Also, in the luminous condition, the children explored the target surroundings, unlike the acoustic condition, in which they reached straight ahead. For these blind children, sound was more relevant to reaching than was the luminous stimulus. The luminous input caused perseveration in congenitally blind children in a similar way that has been reported in the literature for typically-developing, sighted infants, ages 8–12 months, performing A-not-B tasks with visual inputs.
