Trajectories of traumatic stress reactions in children exposed to intimate partner violence.

Background: Understanding different longitudinal patterns of traumatic stress reactions in children exposed to intimate partner violence (IPV) can promote early identification of at-risk children. Objective: Our study aims to explore trajectories of traumatic stress reactions following childhood IPV exposure, and their relation with pa

A coupled agent-based model for France for simulating adaptation and migration decisions under future coastal flood risk

In this study, we couple an integrated flood damage and agent-based model (ABM) with a gravity model of internal migration and a flood risk module (DYNAMO-M) to project household adaptation and migration decisions under increasing coastal flood risk in France. We ground the agent decision rules in a framework of subjective expected utility theory. This method addresses agent's bounded rationality related to risk perception and risk aversion and simulates the impact of push, pull, and mooring factors on migration and adaptation decisions. The agents are parameterized using subnational statistics, and the model is calibrated using a household survey on adaptation uptake. Subsequently, the model simulates household adaptation and migration based on increasing coastal flood damage from 2015 until 2080. A medium population growth scenario is used to simulate future population development, and sea level rise (SLR) is assessed for different climate scenarios. The results indicate that SLR can drive migration exceeding 8000 and 10,000 coastal inhabitants for 2080 under the Representative Concentration Pathways 4.5 and 8.5, respectively. Although household adaptation to flood risk strongly impacts projected annual flood damage, its impact on migration decisions is small and falls within the 90% confidence interval of model runs. Projections of coastal migration under SLR are most sensitive to migration costs and coastal flood protection standards, highlighting the need for better characterization of both in modeling exercises. The modeling framework demonstrated in this study can be upscaled to the global scale and function as a platform for a more integrated assessment of SLR-induced migration

Thinking and Voicing by Adapting and Innovating Employees

This article reports two studies exploring how cognitive style preferences for adaption-innovation affect the likelihood that employees will voice ideas for organizational change toward their supervisors. As hypothesized, Study 1 demonstrates that innovatively compared to adaptively predisposed police officers are less likely to voice conventional ideas and more likely to voice novel ideas for solving work-related problems. Besides a replication of these findings, Study 2 shows how work satisfaction and the quality of the supervisor as voice manager shape the impact of adaption-innovation on employee likelihood to voice. That is, compared to innovators, adaptors are more likely to voice conventional ideas when they are dissatisfied rather than satisfied with work and perceive their supervisors as effective rather than ineffective voice managers. On the other hand, innovators compared to adaptors report greater likelihood to voice novel ideas when they are satisfied rather than dissatisfied with work and perceive their supervisors as effective rather than ineffective voice managers. Theoretical and practical implications of the findings are discussed.</p

Effects of Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) for Young Foster Children with Severe Behavioral Disturbances

Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) has thus far only been tested for diminishing behavior problems in the US. This study tested relative efficacy of MTFC-P on multiple outcomes against treatment as usual in the Netherlands (TAU; Study I), and regular foster care (Study II). The sample included 55 children that received MTFC-P, 23 children received TAU and 30 children from regular foster care (RFC). Changes in behavioral and relationship functioning, trauma symptoms, hypothalamic-adrenal-pituitary (HPA-) axis functioning, and caregiving stress were assessed via questionnaires, interviews, and salivary cortisol. Outcomes of Study I were evaluated using a randomized controlled design and quasi-experimental design, outcomes of Study II according to non-equivalent group comparison. No evidence was found for relative efficacy of MTFC-P over TAU. A treatment effect was found on trauma symptoms, in favor of TAU. Outcomes of Study II revealed that whereas caregiving stress and secure base distortions were significantly more severe at baseline in MTFC-P compared to RFC, post treatment differences were no longer significant. However, percentages of symptoms of disinhibited attachment and attachment disorder were nearly equal between groups at baseline, while post treatment percentages indicated significantly more symptoms in MTFC. In addition, results revealed a significant difference in the severity of externalizing problems post treatment, in favor of RFC. The results obtained within this study indicate that children in MTFC-P and usual treatment foster care in the Dutch context improved similarly, thus not showing the same advantages that MTFC-P has demonstrated in the US. Results should be interpreted with caution due to lower than planned power. Findings underscore the challenges of testing novel treatments across contexts with highly different child welfare provisions
