Substance use among populations displaced by conflict: a literature review.

: This paper reviews the literature on substance use among populations displaced by conflict. Of the 17 publications presenting primary data retained for review, all consider populations in or recovering from protracted conflict, the majority (10) in non-camp settings. Most studies (10) offer prevalence estimates, suggesting that substance use (such as of alcohol, opiates, or minor tranquilizers) is common in some displaced settings. Five describe harmful consequences of substance use among displaced populations (such as HIV transmission, tuberculosis treatment failure, gender-based violence, and economic problems). Three studies suggest risk factors for substance use problems (such as gender, trauma-related conditions, pre-displacement substance use, and socio-economic factors); two examine qualitatively the gendered nature of alcohol-related harm and its links with gender-based violence. One study examines an intervention. The evidence base is weak. Findings are used to develop a conceptual framework emphasizing the risk environment to inform further research, to encourage debate among researchers and practitioners, and to enable the development of interventions

Socio-economic developmental strategies as retail performance indicators: A balanced scorecard approach

This research analyses the commitment to and use of ‘balanced scorecards’ by retailers in generating sustainable profitability, whilst contributing to socio-economic development in South Africa. An international literature review of scorecard frameworks, plans and reports by major retail companies and semi-structured dialogic interviews with a purposive sample of retail business stakeholders and government officials formed the methodology. By contrasting the literature and empirical insights, a summary of findings was generated, which conclude that most retailer scorecards (formal or informal) seek to balance financial with ‘cause-related marketing’ targets, but implementation differs according to factors such as company size, developmental maturity and managerial competence. Furthermore, collaboration between retailers and state institutions in scorecard management is not a reality, as has been achieved in other industries. It is therefore recommended that a Retail Charter scorecard framework be considered, to promote public/private-sector knowledge-sharing and socio-economic developmen

Comparison of Unmanned Aerial Vehicle Platforms for Assessing Vegetation Cover in Sagebrush Steppe Ecosystems

In this study, the use of unmanned aerial vehicles (UAVs) as a quick and safe method for monitoring biotic resources was evaluated. Vegetation cover and the amount of bare ground are important factors in understanding the sustainability of many ecosystems. Methods that improve speed and cost efficiency could greatly improve how biotic resources are monitored on western lands. Sagebrush steppe ecosystems provide important habitat for a variety of species including sage grouse and pygmy rabbit. Improved methods of monitoring these habitats are needed because not enough resource specialists or funds are available for comprehensive on-the-ground evaluations. In this project, two UAV platforms, fixed-wing and helicopter, were used to collect still-frame imagery to assess vegetation cover in sagebrush steppe ecosystems. This paper discusses the process for collecting and analyzing imagery from the UAVs to 1) estimate percentage of cover for six different vegetation types (shrub, dead shrub, grass, forb, litter, and bare ground) and 2) locate sage grouse using representative decoys. The field plots were located on the Idaho National Laboratory site west of Idaho Falls, Idaho, in areas with varying amounts and types of vegetation cover. A software program called SamplePoint was used along with visual inspection to evaluate percentage of cover for the six cover types. Results were compared against standard field measurements to assess accuracy. The comparison of fixed-wing and helicopter UAV technology against field estimates shows good agreement for the measurement of bare ground. This study shows that if a high degree of detail and data accuracy is desired, then a helicopter UAV may be a good platform to use. If the data collection objective is to assess broad-scale landscape level changes, then the collection of imagery with a fixed-wing system is probably more appropriate./En este estudio se evaluó el uso de vehículos aéreos no tripulados (VANT) como un método rápido y seguro para monitorear recursos bióticos. La cubierta vegetal y la cantidad de suelo desnudo son factores importantes para entender la sustentabilidad de varios ecosistemas. Métodos que mejoren la rapidez y el costo podrían mejorar la manera en que los recursos bióticos de las tierras del oeste son monitoreados. El ecosistema de estepa de artemisa provee hábitat para varias especies que incluyen al ganso sage y conejo pigmeo. Es necesario mejorar los métodos de monitoreo de estos hábitat porque no hay suficientes especialistas en recursos o fondos disponibles para evaluaciones completas en el terreno. En este proyecto, se utilizaron dos plataformas de VANT, alas fijas y helicóptero para recolectar imágenes fotográficas para evaluar la cubierta vegetal en un ecosistema de estepa de artemisa. En este artículo se discute el proceso de recolección y análisis de imágenes de un VANT para 1) estimar el porcentaje de cubierta de seis diferentes tipos de vegetación (matorral, matorral seco, zacate, hierbas, mantillo y suelo desnudo) y 2) ubicar gansos sage usando señuelos. Las parcelas experimentales se ubicaron en el Laboratorio Nacional de Idaho sitio localizado en Idaho Falls, Idaho en áreas con diferentes cantidades y tipos de cubierta vegetal. Se uso el programa de software SamplePoint junto con inspecciones oculares para evaluar el porcentaje de cubierta de seis tipos de cubiertas. Los resultados se compararon contra medidas de campo estándar para evaluar su precisión. La comparación de la tecnología de helicóptero VANT y alas fijas contra estimaciones de campo muestra buena relación para las medidas de suelo desnudo. El estudio muestra que sí se requiere alto grado de detalle y precisión en los datos el helicóptero VANT podría ser una buena plataforma para usarse. Pero sí el objetivo de recopilación de datos, es evaluar a gran escala los niveles de cambio en el paisaje entonces, la recopilación de imágenes con el sistema de alas fijas es probablemente más apropiado.The Rangeland Ecology & Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
