Predictors of residential stability among homeless young adults : a cohort study.

Abstract : BACKGROUND: Homelessness episodes have been shown to be associated with serious health outcomes among youth. This study was undertaken to estimate the probability of reaching residential stability over time and to identify predictors of residential stability among homeless young adults aged 18 to 25 years. METHODS: A prospective cohort study was carried out in Montréal, Canada, between April 5(th) 2006 and January 21(th) 2009. Interviews conducted every three months included questions on life conditions and social and mental health factors that are known to influence residential trajectories. Residential status was determined, starting on the first day after recruitment; each follow-up day was classified as a homeless day or a housed day. A period of 90 days was used to define residential stability; therefore the main study outcome was the occurrence of the first consecutive 90 housed days during the follow-up period. Kaplan-Meier and Cox proportional-hazards regression analyses were conducted. RESULTS: Of the 359 participants, 284 reached 90 days of residential stability over the study period, representing an annual probability of 80.5 %. In multivariate analysis, youth who had a high school degree, had a formal sector activity, and those who had sought psychological help were more likely to reach residential stability. Being a man, injecting substances, and having an informal sector activity were associated with a decreased probability to reach residential stability. CONCLUSION: Exposure to factors related to opportunities that promote social integration increases the chance of reaching residential stability. On the other hand, factors related to high level of street entrenchment seem to interfere with stabilization. Maximum efforts should be made to prevent chronic homelessness among youth, targeting not only individual impairments but also hinging on services adapted to foster social connections among the youth

Cognitive Control Reflects Context Monitoring, Not Motoric Stopping, in Response Inhibition

The inhibition of unwanted behaviors is considered an effortful and controlled ability. However, inhibition also requires the detection of contexts indicating that old behaviors may be inappropriate – in other words, inhibition requires the ability to monitor context in the service of goals, which we refer to as context-monitoring. Using behavioral, neuroimaging, electrophysiological and computational approaches, we tested whether motoric stopping per se is the cognitively-controlled process supporting response inhibition, or whether context-monitoring may fill this role. Our results demonstrate that inhibition does not require control mechanisms beyond those involved in context-monitoring, and that such control mechanisms are the same regardless of stopping demands. These results challenge dominant accounts of inhibitory control, which posit that motoric stopping is the cognitively-controlled process of response inhibition, and clarify emerging debates on the frontal substrates of response inhibition by replacing the centrality of controlled mechanisms for motoric stopping with context-monitoring

How do parents manage irritability, challenging behavior, non-compliance and anxiety in children with Autism Spectrum Disorders? A meta-synthesis

Although there is increasing research interest in the parenting of children with ASD, at present, little is known about everyday strategies used to manage problem behaviour. We conducted a meta-synthesis to explore what strategies parents use to manage irritability, non-compliance, challenging behaviour and anxiety in their children with ASD. Approaches included: (1) accommodating the child; (2) modifying the environment; (3) providing structure, routine and occupation; (4) supervision and monitoring; (5) managing non-compliance with everyday tasks; (6) responding to problem behaviour; (7) managing distress; (8) maintaining safety and (9) analysing and planning. Results suggest complex parenting demands in children with ASD and problem behaviour. Findings will inform the development of a new measure to quantify parenting strategies relevant to ASD

Mind wandering and task-focused attention: ERP correlates

Previous studies looking at how Mind Wandering (MW) impacts performance in distinct Focused Attention (FA) systems, using the Attention Network Task (ANT), showed that the presence of pure MW thoughts did not impact the overall performance of ANT (alert, orienting and conflict) performance. However, it still remains unclear if the lack of interference of MW in the ANT, reported at the behavioral level, has a neurophysiological correspondence. We hypothesize that a distinct cortical processing may be required to meet attentional demands during MW. The objective of the present study was to test if, given similar levels of ANT performance, individuals predominantly focusing on MW or FA show distinct cortical processing. Thirty-three healthy participants underwent an EEG high-density acquisition while they were performing the ANT. MW was assessed following the ANT using an adapted version of the Resting State Questionnaire (ReSQ). The following ERP's were analyzed: pN1, pP1, P1, N1, pN, and P3. At the behavioral level, participants were slower and less accurate when responding to incongruent than to congruent targets (conflict effect), benefiting from the presentation of the double (alerting effect) and spatial (orienting effect) cues. Consistent with the behavioral data, ERP's waves were discriminative of distinct attentional effects. However, these results remained true irrespective of the MW condition, suggesting that MW imposed no additional cortical demand in alert, orienting, and conflict attention tasks.Acknowledgements Óscar F.

Analysis of peer-to-peer car sharing potentialities

Car sharing systems have generated increasing interest among drivers and city administrations. The recent European and Italian experiences clearly show that the conditions for the commercial exploitation of this service exist. Aside from traditional car sharing, a possible evolution could be the peer-to-peer car sharing, whose demand and supply have to be estimated. To this aim, a survey was carried out among Milan’s citizens in order to identify the determinants to join a peer-to-peer car sharing. This chapter, after recalling the main studies on this topic, briefly discusses the Milan’s mobility context and its car sharing initiatives. The survey is described, and the results of the econometric analysis, identifying the determinants of car owners’ sharing attitude, are presented. Finally, an estimation of the shared cars’ supply in function of the price set is provided

Introduction

Emigration was rediscovered by the global mainstream academic literature as a valid topic of research in the early 2000s. For over 80 years, migration studies have looked at the immigration side of the story, from the point of view of immigrant-receiving countries (Brettell and Hollifield 2000), paying no attention to the large body of mostly non-Anglophone literature produced in the countries that emigrants were leaving (Stola 1992; Okólski 2009). The re-introduction of the country-of-origin perspective in the 2000s was an important step in the further development of the migration studies field: migrants, after all, are people who come from somewhere. The importance of the countries and communities of origin has been especially brought to light by three streams of academic literature: sociologists and anthropologists focusing on transnationalism (Levitt etc.); political scientists debating the consequences of multiple citizenships and transnational political participation (Østergaard-Nielsen 2003; Bauböck 2010); and economists attempting to capture the impact of remittances (Ratha 2005). At the same time, the term 'diaspora', which indicates an outer group that is linked in some way with the homeland, has had an incredible trajectory: it left the narrow field of classic diaspora studies and went out to the wider world, changing the landscape of various fields of investigation: sociology, anthropology, political science and economics (Van Hear 2006; Bauböck and Faist 2010; Bilgili and Siegel 2013; Ragazzi 2014; Kshetri et al. 2015)
