Functional connectivity abnormalities during contextual processing in schizophrenia and in Parkinson’s disease

Functional connectivity was evaluated in patients with schizophrenia (SC) and in patients with Parkinson’s disease (PD) during the performance of a local contextual processing paradigm, to investigate the proposition that functional disconnection is involved with contextual processing deficits in these populations. To this end, we utilized event-related EEG signals, synchronization likelihood and graph theoretical analysis. Local context was defined as the occurrence of a predictive sequence of stimuli before the presentation of a target event. In the SC patients, we observed a decrease in path length (L) in the beta band, for the predictive sequence and for predicted and random targets, compared with controls. These abnormalities were associated with weaker frontal-temporal-parietal connections. In the PD patients we found longer L (theta band) for predicted targets, and higher cluster coefficients for both the predictive sequence (theta band) and predicted targets (alpha and theta bands), compared with controls. Detection of predicted targets was associated with weaker frontal-parietal connections in PD. No group differences were found for randomized standard stimuli in both SC and PD patients. These findings provide evidence of task-specific functional connectivity abnormalities within frontal networks during local contextual processing.     

Opening Scenarios: A Relational Perspective on How to Deal with Multiple Therapeutic Views

The aim of this work is to provide therapists with a conceptual outline to help them utilize theoretical and methodological perspectives from different psychotherapy models. More specifically, we will start with three basic assumptions from the social constructionist paradigm, particularly effective in bringing together different perspectives in therapy and providing therapists with useful criteria for selecting among them. The assumptions are as follows: (1) the psychological world of the individual is constructed within relational processes, mainly through dialogue; (2) in general, discourse can be classified as either generative or degenerative; and (3) individuals construct their life narratives based also on a common-sense that can derive from psychological theories developed within specific cultural traditions. These assumptions derive mainly from Gergen??s relational perspective (2009) and lead us to foresee a set of implications for clinical practice, where therapist and client are seen as ??multi-beings??, consequently endowed with multiple views, not one.     

How many lives can bloody and shocking road safety advertising save? The case of Spain

At the beginning of the 21st century, the punishment strategies used by the Spanish administration were considerably hardened to achieve a reduction in road accidents. This hardening could also be seen in the mass-media public advertising campaigns, with a marked shift from gentle messages to threat-based advertisements.The goal of this study is to evaluate the effectiveness of this radical change in terms of main road accident indicators and the time that the effects last using multivariate unobserved component models set up in a state space framework applied to monthly series for the 1980–2008 period. The main conclusion is that the effect on reducing road accidents is no greater when citizens are subjected to a greater level of threats in advertising campaigns than would on average be achieved using campaigns with a low level of threats. Secondly, the impact of bloody advertising in Spain is limited to the most serious accidents, those that cause deaths, either on highways or in built-up areas. Moreover, the positive effects progressively decrease as the average lifespan for significant effects of medium and high level campaigns on deaths on highways or in built-up areas was 8 months and almost 12 days. The results show that a reduction in numbers of deaths and injuries is always achieved when the level of harshness in the messages is increased after a period of several years of mild advertising.

The WHO/START Study: Promoting Suicide Prevention for a Diverse Range of Cultural Contexts

The WHO/Start Study is introduced and described in its four main components. The study originated as a response to growing concerns about trends of suicide, the prevalence of which in the Western Pacific Region of the World Health Organization is the highest among the six regions of the WHO. So far, nineteen centers have joined the study. This ambitious project is expected to provide important transcultural perspectives on both fatal and nonfatal suicidal behaviors, together with increased awareness for these phenomena and the growth of culture‐sensitive prevention programs.     

Perspectivity,Intersubjectivity, Normativity: On Malpas’s Place and Experience

ABSTRACT

The publication of the revised edition of Jeff Malpas’s Place and Experience in 2018 gives the opportunity to reconsider this book (originally published in 1999) and the debates that it originally sparked. In this article, I focus on Malpas’s characterization of space as subjective, allocentric, and objective and I approach them in conjunction with other notions and considerations that, I suggest, are useful to expand and complement Malpas’s central theses. I approach the concept of subjective space in conjunction with the notion of coenaesthesis and with Heidegger’s notion of mineness (Jemeinigkeit); the concept of allocentric space by addressing Malpas’s critique of Nagel’s notion of detachment; and the concept of objective space through a discussion of the issue of perspective in light of Merleau-Ponty’s critique of Leibniz’s notion of ‘géométral’ (geometrized projection). These analyses pave the way for a discussion of some possible normative implications of the conception of place and subjectivity that emerges from Malpas’s Place and Experience against the background of Heidegger’s thought, and particularly in relation to Heidegger’s notion of dwelling (Wohnen).     

Contemporary Definitions of Suicidal Behavior: A Systematic Literature Review

To address the lack of comparability around the world, we conducted a systematic review of existing definitions of suicide and suicidal behaviors. In the literature, four key features appear to cover the vast majority of concepts underpinning definitions: agency, knowledge of a potential fatal outcome, intent, and outcome. Intent and outcome appear to be the most consensual features of definitions of suicide, albeit revealing interesting conceptual variations. The four key features could be used to devise a research tool able to explore the meanings of suicide across different countries and different cultures.
