Conflict, including the threat or fear of potential violence, or being witness to or a victim of physical violence, constantly surrounds gangs and their communities and is the principal driver sustaining gang life. This Special Issue examines the diverse nature of gang-related violence with the goal of better understanding the growing complexities of gang violence over the last two decades to better inform public policy solutions. The contributions included in this Special Issue highlight the complex nature of gang-related violence in the 21st Century. As much as policy makers, the media, and even scholars like to simplify gang-related violence, all of the studies included in this Special Issue highlight the nuance and variation that exists.

In this issue, psychometrics researchers were invited to make reanalyses or extensions of a previously published dataset from a recent paper by Myszkowski and Storme (2018). The dataset analyzed consisted of responses to a multiple-choice logical reasoning nonverbal test, comprising the last series of Raven’s (1941) Standard Progressive Matrices. Although the original paper already proposed several modeling strategies, this issue presents new or improved procedures to study the psychometrics properties of tests of this type.

This special edition, Seafood Sustainability Series I, includes two articles on seafood consumption, four on sustainable capture fisheries, and four on sustainable aquaculture. The articles on consumption explore an alternative perspective on sustainable seafood movement governance to consumer- or retail/brand-driven logic and analyze fish tissues for human consumption to detect contaminants like flame retardant chemicals hazardous to human health sourced from microplastic pollutants. Articles on capture fisheries include: • A study of harvest strategies to achieve ecological, economic, and social sustainability objectives; • An examination of the economic leverages and resources needed to sustain coastal artisanal fishing communities in Africa; • A review of sustainability planning efforts to combat fishing community threats like declining participation, aging infrastructure and fleets, gentrification, reduced resource access, market competition, and environmental stresses; • An analysis of responsible fish consumption through a life-promoting sustainable food system for school-age children. Three of the articles on aquaculture focus on studying consumer preferences related to sustainable aquaculture based on the estimation of how the attributes of aquaculture products (including product labeling and perception) affect consumers’ purchase decisions. The other article questions the widely held assumption of sustainable substitutability of plant protein sources (e.g., soymeal) for fishmeal in aquaculture production.
