This second of two articles describes the application of disaster mental health interventions within the context of the childs social ecology consisting of the Micro-, Meso-, Exo-, and Macrosystems. Microsystem interventions involving parents, siblings, and close friends include family preparedness planning andpractice, psychoeducation, role modeling, emotional support, and redirection. Mesosystem interventions provided by schools and faith-based organizations include safety and support, assessment, referral, and counseling. Exosystem interventions include those provided through community-based mental health programs, healthcare organizations, the workplace, the media, local volunteer disaster organizations, and other local organizations. Efforts to build community resilience to disasters are likely to have influence through the Exosystem. The Macrosystem - including the laws, history, cultural and subcultural characteristics, and economic and social conditions that underlie the other systems - affects the child indirectly through public policies and disaster programs and services that become available in the child's Exosystem in the aftermath of a disaster The social ecology paradigm, described more fully in a companion article (Noffsinger Pfefferbaum, Pfefferbaum, Sherrieb, & Norris,2012), emphasizes relationships among systems and can guide the development and delivery of services embedded in naturally-occurring structures in the child's environment.

Psychological distress, including anxiety or mood disorders, emanates from the onset of chronic/unpredictable stressful events. Symptoms in the form of maladaptive behaviors are learned and difficult to treat. While the origin of stress-induced disorders seems to be where learning and stress intersect, this relationship and molecular pathways involved remain largely unresolved.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Subjective feelings are thought to arise from conceptual and bodily states. We examine whether the valence of feelings may also be decoded directly from objective ecological statistics of the visual environment. We train a visual valence (VV) machine learning model of low-level image statistics on nearly 8000 emotionally charged photographs.

In social animals, group dynamics profoundly influence collective behaviours, vital in processes like information sharing and predator vigilance. Disentangling the causes of individual-level variation in social behaviours is crucial for understanding the evolution of sociality. This requires the estimation of the genetic and environmental basis of these behaviours, which is challenging in uncontrolled wild populations.

Insects represent most of terrestrial animal biodiversity, and multiple reports suggest that their populations are declining globally due to anthropogenic impacts. Yet, a high proportion of insect species remain undescribed and limited data on their population dynamics hamper insect conservation efforts. This is particularly critical in tropical biodiversity hotspots such as Southeast Asia.
