Description of a method for localizing swarming mosquitoes and other insects in 3D space with visualizations

Male mosquitoes swarm to find mates, but the characteristics of these swarms have not yet been quantitatively analyzed in the field. This paper describes a simple method used recently to localize individual Anopheles gambiae in a swarm via stereoscopic image analysis of video footage swarms recorded in Doneguebougou, Mali. The methods described here represent a streamlining of simple triangulation for insect localization in the hope that other researchers will be able to apply the method for studying fundamental questions about flying insects or other taxa.&#xd;&#xa

The Potential to Promote Resilience: Piloting a Minority Stress-informed, GSA-based, Mental Health Promotion Program for LGBTQ Youth

This article describes the results of a pilot study to determine the feasibility and acceptability of a mental health promotion program that was developed to address minority stressors and promote coping skills among lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. It was hypothesized that the program would be feasible to implement within the context of a gay–straight alliance (GSA) and that GSA members would find the program acceptable (e.g., educational, enjoyable, helpful, and relevant). Participants included 10 members of a high school GSA in the northeastern United States. The program sessions were delivered during GSA meetings. The first session emphasized the identification of minority and general stressors, which was followed by a discussion of coping strategies. The remaining sessions emphasized the development of cognitive coping, affect regulation, and problem-solving skills. After each session, participants completed a 13-item feedback form. Ten items assessed acceptability and 3 open-ended items allowed participants to provide constructive feedback. Although the program was feasible to implement within the GSA setting, attendance at the sessions was variable. Those who attended the sessions reported them to be enjoyable, informative, relevant to their lives, and potentially helpful for other LGBTQ students. After revising the program, future research is needed to investigate its dissemination potential and determine whether the program can disrupt the minority stress–psychiatric distress relationship

Social Entrepreneurship That Truly Benefits the Poor: An Integrative Justice Approach

The phenomenal growth of social entrepreneurship over thelast decade has ably demonstrated how technology, innovation, and anentrepreneurial spirit can afford better solutions to the vexing social andenvironmental problems of our time than can traditional aid and charitybasedefforts. In most cases, but not always, the poor and disadvantagedhave benefited from the growth of social entrepreneurship. In order toensure that social entrepreneurship does indeed benefit the poor, it isimperative that there be normative guidelines for fair and just engagementwith impoverished populations. A model that has been presented in themarketing and public policy literature is the integrative justice model (IJM)for impoverished populations. While the IJM was developed primarily in thecontext of multinational corporations (MNCs) operating in emerging markets,its applicability extends beyond MNCs. This article attempts to apply theIJM principles in the context of social entrepreneurship in order to providesocial entrepreneurial organizations (SEOs) with a normative frameworkaimed at ensuring that the poor truly benefit from their activities. Basedon this framework, the article suggests certain areas to which SEOs oughtto be particularly attentive in their practice. The article also makes somesuggestions for further research

Open-Access Fishery Models: Relaxing a Constraint and Removing an Econometric Obstacle

Over the past 30 years, a widely accepted model of "open-access" fisheries has been developed, yet empirical tests of the standard model have been relatively few. One difficulty is that fish stocks, the levels of which affect the rate of catch, are not directly observable. Simplifying assumptions are generally required, such as the assumption that catchability does not change over time. Estimation on the basis of the standard model also raises difficulties in specification, if contemporaneous correlation of the error term with one of the regressors is to be avoided. This paper describes an algorithm that imposes a less restrictive pattern (than constancy) on catchability, yet does so in an econometrically acceptable fashion. It also reports on an application of this algorithm to the Flemish Cap groundfishery over the period from 1971 to 1985.Environmental Economics and Policy, Research Methods/ Statistical Methods, Resource /Energy Economics and Policy, catchability, error term, bias, Flemish Cap,

Edge diffraction of a convergent wave

Closed-form solutions have been derived for the diffraction patterns at the focal plane of (1) a convergent wave of unit amplitude illuminating a segment of a circular aperture and (2) a convergent wave of Gaussian amplitude diffracted by an infinite edge. Photographs showing the main features of these edge transform patterns are presented together with computer-generated graphs
