Glossiness disrupts predator localisation of moving prey.

Movement is the "enemy of camouflage", but most animals must move to find resources, such as mates, food and shelter. Therefore, strategies that disrupt predator localization or speed perception of moving prey can play a crucial role in prey survival. Shiny or glossy appearances, which are characterised by having a high degree of specular (mirror-like) reflection of incident light, can disrupt predator hunting behaviours towards moving prey.

Trauma-informed interactions within a trauma-informed homeless service provider: Staff and client perspectives.

This study aims to provide practical insights for developing trauma-informed interaction strategies between service providers and participants in homeless service organizations (HSOs). Twelve providers and 17 participants were interviewed for a qualitative study on trauma-informed care (TIC) within an HSO. Thematic analysis revealed six themes regarding provider approaches to TIC interactions with participants: provide a sounding board, promote safety, foster understanding and respect, build relationships and trust, facilitate connection to services, and ensure flexibility in service provision.

Conflict and Climate Factors and the Risk of Child Acute Malnutrition Among Children Aged 24-59 Months: A Comparative Analysis of Kenya, Nigeria, and Uganda.

Acute malnutrition affects a sizeable number of young children around the world, with serious repercussions for mortality and morbidity. Among the top priorities in addressing this problem are to anticipate which children tend to be susceptible and where and when crises of high prevalence rates would be likely to arise. In this article, we highlight the potential role of conflict and climate conditions as risk factors for acute malnutrition, while also assessing other vulnerabilities at the individual- and household-levels.

Investigating the relationship between growing season quality and childbearing goals.

Agricultural production and household food security are hypothesized to play a critical role connecting climate change to downstream effects on women's health, especially in communities dependent on rainfed agriculture. Seasonal variability in agriculture strains food and income resources and makes it a challenging time for households to manage a pregnancy or afford a new child. Yet, there are few direct assessments of the role locally varying agricultural quality plays on women's health, especially reproductive health.

Meta-analyses of teacher-delivered trauma-based and trauma-informed care interventions.

Objective: Children impacted by adversity and trauma often experience psychological, emotional, behavioral, and academic difficulties. To address these concerns, there is a growing call for trauma-informed school systems to better support students with trauma histories. Teacher involvement in trauma-informed approaches is vital but understudied.

Designing a Pest and Disease Outbreak Warning System for Farmers, Agronomists and Agricultural Input Distributors in East Africa.

Early warnings of the risks of pest and disease outbreaks are becoming more urgent, with substantial increases in threats to agriculture from invasive pests. With geospatial data improvements in quality and timeliness, models and analytical systems can be used to estimate potential areas at high risk of yield impacts. The development of decision support systems requires an understanding of what information is needed, when it is needed, and at what resolution and accuracy.

Social support and networks among people experiencing chronic homelessness: A systematic review.

The objectives of this systematic review were to synthesize available information on social support and social networks among individuals experiencing chronic homelessness, examine the measurement of social support, the impact of social support on outcomes, and the impact of interventions on social support. The authors searched Academic Search Complete, PsycArticles, Pubmed, PsycINFO, ScienceDirect, Cinahl, and ProQuest for English-language empirical articles published between 1998 and 2019. Studies were included if they sampled single and unaccompanied adults experiencing chronic homelessness and examined the impact of social support and/or social networks.

Sustainable food systems and nutrition in the 21st century: a report from the 22nd annual Harvard Nutrition Obesity Symposium.

Food systems are at the center of a brewing storm consisting of a rapidly changing climate, rising hunger and malnutrition, and significant social inequities. At the same time, there are vast opportunities to ensure that food systems produce healthy and safe food in equitable ways that promote environmental sustainability, especially if the world can come together at the UN Food Systems Summit in late 2021 and make strong and binding commitments toward food system transformation. The NIH-funded Nutrition Obesity Research Center at Harvard and the Harvard Medical School Division of Nutrition held their 22nd annual Harvard Nutrition Obesity Symposium entitled "Global Food Systems and Sustainable Nutrition in the 21st Century" in June 2021.

Considering climate and conflict conditions together to improve interventions that prevent child acute malnutrition.

Despite early warning signs about threats to food security, humanitarian interventions often lag behind these warning signs. Climate and conflict conditions are among the most important factors preceding food system failures and malnutrition crises around the world. Research shows how conflict and climate conditions can upend functional food and economic systems, but this research does not address the severe health impacts of these conditions on infants and young children.

Neighborhood Socioeconomic Resources and Crime-Related Psychosocial Hazards, Stroke Risk, and Cognition in Older Adults.

Living in neighborhoods with lower incomes, lower education/occupational levels, and/or higher crime increases one's risk of developing chronic health problems including cardiovascular disease risk factors and stroke. These cardiovascular health problems are known to contribute to cognitive decline and dementia. The purpose of this study was to determine the association of neighborhood socioeconomic resources and crime-related psychosocial hazards on stroke risk and cognition, hypothesizing that cardiovascular health would mediate any relationship between the neighborhood-level environment and cognition.

Identifying a typology of homelessness based on self-sufficiency: Implications for rapid re-housing interventions.

Limited research exists on the characteristics of individuals experiencing homelessness who achieve positive housing outcomes in rapid re-housing (RRH) interventions. We aimed to identify a typology of homelessness based on Self-Sufficiency Matrix (SSM) domains and examine its relation to sociodemographic characteristics and housing placement through RRH. Homeless Management Information System data, including sociodemographics, SSM domains, and housing outcomes, were obtained for 261 Homelessness Prevention and Rapid Re-housing Program participants in Indianapolis, Indiana, from 2009 to 2012.

Domestic migration and mobile phones: A qualitative case study focused on recent migrants to Ouagadougou, Burkina Faso.

Migration has long been used as a strategy for livelihood diversification in rural, subsistence communities. Yet in order for migration to effectively serve as a livelihood diversification strategy, it should meet certain conditions: migration should ease financial burdens, should confer access to economically valuable resources and information, and should broaden social networks. Using qualitative data gathered in 25 interviews with rural migrants to Ouagadougou, Burkina Faso, we examine how mobile phone technology has impacted migration as a livelihood diversification strategy.

Attempting Randomized Housing First Research in a Community Context: Reflections on Failure.

The Housing First (HF) model of permanent supportive housing for individuals experiencing chronic homelessness has a strong evidence base that has largely been driven by researchers in the field of community psychology in partnership with community-based organizations. However, important gaps in the HF literature remain. Implementing rigorous research designs to further the evidence for HF requires immense resources to fund both the housing intervention and the research activities.

Stressors of Rape Crisis Work From the Perspectives of Advocates With and Without Sexual Assault Victimization History.

Rape crisis centers largely rely on volunteers for delivering emergency room advocacy to survivors of sexual assault. Volunteer advocates bear witness to trauma as part of their role, such as when listening to details of sexual assault. This exposure may negatively affect advocates long term, which may lead to secondary traumatic stress and vicarious traumatization, and possibly reduce their ability to provide quality services and remain in their role.

Mapping the effects of drought on child stunting.

As climate change continues, it is expected to have increasingly adverse impacts on child nutrition outcomes, and these impacts will be moderated by a variety of governmental, economic, infrastructural, and environmental factors. To date, attempts to map the vulnerability of food systems to climate change and drought have focused on mapping these factors but have not incorporated observations of historic climate shocks and nutrition outcomes. We significantly improve on these approaches by using over 580,000 observations of children from 53 countries to examine how precipitation extremes since 1990 have affected nutrition outcomes.

Intention to Read to Newborns Following a Brief Reading Promotion Intervention among Low-Income Pregnant Women.

Introduction: Reading to children can increase word knowledge and success in school. The American Academy of Pediatrics recommends beginning reading at birth. However, children from low-income families are exposed to less words, including reading exposure, than children from high-income families.

Psychometric properties of the self-sufficiency matrix among homeless and vulnerably housed individuals and families.

Homeless service systems have been implementing assessment tools to inform service provision for individuals and families. Although a variety of assessments are available, their psychometric evidence base is limited. The self-sufficiency matrix (SSM) is one assessment that demonstrates promising reliability and validity.

Predictors of employment outcomes in a comprehensive service program for individuals experiencing chronic homelessness.

This study examined predictors of employment service referral and employment outcomes among individuals experiencing chronic homelessness participating in a comprehensive service program emphasizing housing placement and economic independence. The sample included all participants enrolled in the program. Participants self-determined whether to be referred for employment services.

Permanent Housing Placement and Reentry to Services Among Family Recipients of Homelessness Prevention and Rapid Re-Housing Program (HPRP) Assistance.

The Homelessness Prevention and Rapid Re-Housing Program (HPRP) provided individuals and families who were either at-risk or currently experiencing homelessness with time-limited financial and housing support services. Evaluations of HPRP showed a high rate of family placement into permanent housing. However, little research has explored immediate and longitudinal outcomes for families enrolled in HPRP.

The housing first technical assistance and training (HFTAT) implementation strategy: outcomes from a mixed methods study of three programs.

Background: This paper discusses the initial testing of the Housing First Training and Technical Assistance (HFTAT) Program, a multifaceted, distance-based strategy for the implementation of the Housing First (HF) supportive housing model. HF is a complex housing intervention for serving people living with serious mental illness and a substance use disorder that requires significant individual- and structural-level changes to implement. As such, the HFTAT employs a combined training and consultation approach to target different levels of the organization.

Uncertainties of potentials and recent changes in global yields of major crops resulting from census- and satellite-based yield datasets at multiple resolutions.

Global agriculture is under pressure to meet increasing demand for food and agricultural products. There are several global assessments of crop yields, but we know little about the uncertainties of their key findings, as the assessments are driven by the single best yield dataset available when each assessment was conducted. Recently, two different spatially explicit, global, historical yield datasets, one based on agricultural census and the other largely based on satellite remote sensing, became available.

Diastereoselective Synthesis of Unnatural Amino Acids by Alkylation of α- tert-Butanesulfinamide Auxiliary-Bound Enolates.

A new chiral auxiliary for the diastereoselective alkylation of amino ester enolates that takes advantage of chiral information stored on the enolate side of the amino ester substrate has been developed. Chiral α-sulfinamido esters were alkylated under basic conditions in good yields (up to 90%) and good to high diastereoselectivities (generally >6:1) to provide unnatural mono- and α,α-disubstituted amino acid derivatives. This auxiliary allowed for the ready conversion of ester functionality without the need for esoteric reagents.

Housing status among single adults following Homelessness Prevention and Rapid Re-housing Program participation in Indianapolis.

The Homelessness Prevention and Rapid Re-housing Program (HPRP) was a federally-funded program in the United States that provided short-term financial and support services to individuals and families who were at-risk or currently experiencing homelessness. There is limited research on factors that predict placement in permanent housing following prevention and rapid rehousing interventions, particularly for single adult populations. The present study examined demographic and program-related predictors of permanent housing upon program exit among two groups of adults enrolled in HPRP in Indianapolis, IN: Homelessness Prevention (HP) recipients (n = 219) and Rapid Re-housing (RRH) recipients (n = 296).

Trauma Intervention in Sub-Saharan African Children: A Systematic Literature Review.

Sub-Saharan Africa is a part of the world that is highly affected by a large number of atrocities, causing a myriad of financial, physical health, and mental health consequences. Yet, unfortunately, according to the World Health Organization (WHO), this is also the part of the world that is least served by mental health services. In response, the WHO has created mandates to increase mental health resources and capacity in all countries.
