Individual Differences in Novelty-Seeking and Behavioral Responses to Nicotine: A Review of Animal Studies
2010
Individual differences in the behavioral responses to a novel environment have been proposed as a research tool to predict responsiveness to other behavioral tasks, response to certain events and individual vulnerability to nicotine addiction. In rats and mice, novelty seeking (defined as enhanced specific exploration of novel situations) is a complex behavior confirmed by a large body of neurochemical, endocrinological and behavioral data. We review the main standardized procedures employed to measure the novelty seeking trait in rodents and the ontogeny of this behavior throughout the life-span taking into account that novelty seeking can be permanently modified as a consequence of partic…
Impacts of volcanic hazards on rural communities and adaptative strategies: A case study of the Virunga Volcanic Province (Democratic Republic of Con…
2023
co auteur étranger; International audience; Active volcanoes are a continuous threat for several regions worldwide and cause socio-economic and environmental issues, including the Virunga Volcanic Province (D.R. Congo). There, more than 2 million people are permanently exposed to the hazards of the most active volcanoes in Africa: Nyiragongo and Nyamulagira. However, there is a clear lack of information regarding the impacts of these hazards and how they may be affected by social vulnerability. In this study, a household survey based on semi-structural interviews was performed for rural communities in Virunga. This research aims to (i) investigate the impacts of volcanic hazards on rural co…
Part 3. A question of perspective: The association between intrusive thoughts and obsessionality in 11 countries
2014
Abstract A key assumption of contemporary cognitive-behavioral models of obsessive–compulsive disorder (OCD) is that obsessional thoughts exist on a continuum with “normal” unwanted intrusive thoughts. Recently, however, some authors have challenged this notion. The present study aimed to clarify (a) the extent that different types of intrusive thoughts in nonclinical individuals are associated with obsessionality, (b) the relative contribution of frequency, distress and control ratings to obsessionality, and (c) the extent that existing findings (primarily from North American or European samples) generalize to other countries in the world. Five hundred and fifty-four non clinical individua…
Análisis del riesgo de exclusión social en el medio rural: el índice Z como solución «lowcost» a la falta de indicadores sintéticos municipales
2019
Tras la crisis de 2008 el estudio de la exclusión social resulta un objeto recurrente para las investigaciones rurales. Pero las aproximaciones habituales suelen emplear perspectivas de análisis macro (como la tasa AROPE), algo inadecuado cuando el medio rural se caracteriza por su heterogeneidad. Si no reconocemos esta, difícilmente se puede lograr la inclusión social de los individuos y/o familias excluidas en este. Luego resulta clave evidenciar las diferencias territoriales de los fenómenos de exclusión social a nivel micro. Para ello trabajamos con la delimitación que de ruralidad emplean los PDR, y tomamos como casos de estudio los municipios de los GAL-LEADER de la provincia de Valen…
Spatial risks and complex systems: methodological perspectives
2007
Research on risk and industrial catastrophes question the complexity theories. Besides the concepts of complexity which lead us to reconsider concepts of risk, hazard and vulnerability, we propose to think about more practical aspects, for example the modelling of human behaviour in crisis situations. The link between concepts as critical self-organization, emergence, bifurcation, and the methods in the Distributed Artificial Intelligence (DAI) used to model them is however difficult. In this paper, we present ongoing analysis on the key concepts of risk science, such as hazards and catastrophes. We propose to enrich them with complex systems theories. First, we present methodological persp…
The International Legal Framework on Human Trafficking
2020
Approaching the issue of human trafficking, especially when referring to exploitation for sexual purposes, means dissecting concepts and ‘placing’ ourselves within the current binary scholar debate on exploitation and sex work. This chapter presents a chronological excursus on the several international treaties on the issue of human trafficking, with a particular focus on the concept of sexual exploitation. The author delimitates the concept in order to present a precise definition and exclude potential misconceptions that could mislead the reader, especially when vague concepts are included such as vulnerability and consent. Based on an analysis of the current academic debate, as well as t…
Structural contagion and vulnerability to unexpected liquidity shortfalls
2012
This paper assumes that financial fluctuations are the result of the dynamic interaction between liquidity and solvency conditions of individual economic units. The framework is an extention of Sordi and Vercelli (2012) designed as an heterogeneous agent model which proceeds through discrete time steps within a finite time horizon. The interaction at the micro-level between economic units monitors the spread of contagion and systemic risk, producing interesting complex dynamics. The model is analysed by means of numerical simulations and systemic risk modelling, where local interaction of units is captured and analysed by the bilateral provision of liquidity among units. The behaviour and e…
Time and Performance Pressure
2018
Abstract. Time pressure and performance pressure are among the most crucial job demands of today’s workforce. However, the literature on psychological stress barely distinguishes between these constructs. Therefore, we aimed to examine time pressure and performance pressure as two qualitatively different job demands in terms of unique moderators for both demands. We investigated whether time control would moderate the relationship between time pressure and both emotional exhaustion and work engagement. As a vulnerability factor for dealing with performance pressure, we investigated perfectionism. The cross-sectional data of 167 employees showed that time control was a significant moderator…
Decision Making Impairment: A Shared Vulnerability in Obesity, Gambling Disorder and Substance Use Disorders?
2016
Introduction Addictions are associated with decision making impairments. The present study explores decision making in Substance use disorder (SUD), Gambling disorder (GD) and Obesity (OB) when assessed by Iowa Gambling Task (IGT) and compares them with healthy con- trols (HC). Methods For the aims of this study, 591 participants (194 HC, 178 GD, 113 OB, 106 SUD) were assessed according to DSM criteria, completed a sociodemographi c interview and con- ducted the IGT. Results SUD, GD and OB present impaired decision making when compared to the HC in the over- all task and task learning, however no differences are found for the overall performanc e inthe IGT among the clinical groups. Results…
El impacto de la gran recesión en la Comunidad Valenciana
2013
La gran recesión ha tenido un impacto importante sobre la estructura de la pobreza y la privación en la población de la Comunidad Valenciana. Exceptuando el grupo de las personas de más edad, todos los demás se han visto afectados por esta crisis en mayor o menor medida. No solo ha crecido el porcentaje de familias que está por debajo del umbral de la pobreza o que están privadas de algunos bienes o servicios básicos, sino que también ha aumentado la intensidad de estos fenómenos pudiendo afirmarse que las personas pobres y privadas de bienes lo son ahora con mayor intensidad que antes de la crisis. El presente artículo expone de una manera resumida los principales datos del estudio realiza…
