Cultural, sociopolitical, environmental and built assets supporting health and well-being in Torres Strait Island communities: protocol for a scoping review.

Introduction: Risks to an individual's health should be considered alongside the environmental, sociocultural and sociopolitical context(s) in which they live. Environmental mapping is an approach to identifying enablers and barriers to health within a community. The Indigenous Indicator Classification System (IICS) framework has been used to map the environment in Australian Indigenous communities.

Growth dynamics and amorphous-to-crystalline phase transformation in natural nacre.

Biominerals, such as nacreous bivalve shells, are important archives of environmental information. Most marine calcifiers form their shells from amorphous calcium carbonate, hypothesised to occur via particle attachment and stepwise crystallisation of metastable precursor phases. However, the mechanism of this transformation, including the incorporation of trace elements used for environmental reconstructions, are poorly constrained.

The Welcome Baby Program: An Implementation and Outcomes Evaluation.

In 2015, First 5 LA contracted with the RAND Corporation to perform an implementation and outcomes evaluation of its Welcome Baby universal home visitation program. RAND designed and executed a mixed-methods implementation and outcomes evaluation program that examined program fidelity across 12 sites in Los Angeles County, each site's community referral and resource process, staff and participant experiences with the program, factors that may influence program attrition, short-term outcomes, and the relationship between program fidelity and outcomes. Data from multiple sources were used, including interviews with staff and focus groups with participants, quantitative data from staff and participant surveys, data collected by staff and entered into an administrative database, and document review.

Single-cell visualization indicates direct role of sponge host in uptake of dissolved organic matter.

Marine sponges are set to become more abundant in many near-future oligotrophic environments, where they play crucial roles in nutrient cycling. Of high importance is their mass turnover of dissolved organic matter (DOM), a heterogeneous mixture that constitutes the largest fraction of organic matter in the ocean and is recycled primarily by bacterial mediation. Little is known, however, about the mechanism that enables sponges to incorporate large quantities of DOM in their nutrition, unlike most other invertebrates.
