Wild bee abundance declines with urban warming,regardless of floral density

As cities expand, conservation of beneficial insects is essential to maintaining robust urban ecosystem services such as pollination. Urban warming alters insect physiology, fitness, and abundance, but the effect of urban warming on pollinator communities has not been investigated. We sampled bees at 18 sites encompassing an urban warming mosaic within Raleigh, NC, USA. We quantified habitat variables at all sites by measuring air temperature, percent impervious surface (on local and landscape scales), floral density, and floral diversity. We tested the hypothesis that urban bee community structure depends on temperature. We also conducted model selection to determine whether temperature was among the most important predictors of urban bee community structure. Finally, we asked whether bee responses to temperature or impervious surface depended on bee functional traits. Bee abundance declined by about 41% per °C urban warming, and temperature was among the best predictors of bee abundance and community composition. Local impervious surface and floral density were also important predictors of bee abundance, although only large bees appeared to benefit from high floral density. Bee species richness increased with floral density regardless of bee size, and bee responses to urban habitat variables were independent of other life-history traits. Although we document benefits of high floral density, simply adding flowers to otherwise hot, impervious sites is unlikely to restore the entire urban pollinator community since floral resources benefit large bees more than small bees.     

Self-Care Practice in Social Work Education: A Systematic Review of Interventions

Social work is a demanding profession as practitioners routinely face difficult situations that affect their well-being. The National Association of Social Workers strongly supports self-care practice as an approved mechanism to offset these challenges, yet practitioners report not learning techniques necessary to perform self-care. In this study, a systematic review compliant with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards was conducted to identify evidence-based interventions used to improve student self-care practice in social work education. In the four studies meeting inclusion criteria, mindfulness practice was the only empirically evaluated self-care strategy reported—and with mixed results. Mindfulness activities enable social workers to sustain their well-being and is critical to modeling and providing effective service delivery to clients. Areas for further research are indicated.     

Secondary Traumatic Stress in Social Workers Responding to Disasters: Reports from the Field

Social workers are called to respond to disasters to provide assessment, crisis counseling and trauma treatment as part of the recovery effort. While research has identified the types of interventions appropriate in assisting trauma survivors, little empirical research exists to help address the distress responses that social workers experience when exposed to the trauma material of disaster survivors and their families. Case examples can inform social work practice using evidence informed interventions and recording the outcomes. This article presents three case histories of social workers responding to disasters, the course of their secondary traumatic stress responses and their struggle to overcome the psychological adversity they faced.

Strengthening Social Work Approaches Through Advancing Knowledge of Early Childhood Intervention

Early childhood professionals—social workers, educators, speech therapists, occupational therapists, physical therapists, pediatricians, and others—create the foundation for a life-long duration of experiences that families, who have children with disabilities, will have with various professional groups. The nature of the early childhood interventionists' interaction, treatment, services or supports of the child and the attitudes conveyed to families during these critical early years may be a significant factor in the willingness of families and young adults to continue to pursue therapeutic and supportive services. With insights into early intervention best practices, social workers are likely to find themselves in a preferred position to plan appropriate family-focused intervention strategies that may encourage success and prevent complications or a worsening of specific initial conditions among children with disabilities.     

What's Missing from National Landline RDD Surveys?: The Impact of the Growing Cell-Only Population

The number of cell phone only households has continued to grow– 12.8 percent of all households by the end of 2006, accordingto the National Health Interview Survey (NHIS). To assess theextent and nature of the potential bias in landline telephonesamples created by the absence of cell-only households, thePew Research Center conducted four independent dual frame studiesin 2006, three of which included at least 200 interviews withcell-only respondents. Despite the fact that there are significantdifferences between cell-only and landline respondents on manyimportant variables, across the four surveys with differentsubstantive content we find that including a cell-only samplewith a landline RDD sample produces general population estimatesthat are nearly identical to those from the landline samplealone. Yet, while the noncoverage problem is currently not damagingestimates for the entire population, we find evidence that itdoes create biased estimates on certain variables for youngadults, 25 percent of whom are cell-only according to the mostrecent government estimate.     

Growing Fair Trade in South Africa

Fairtrade certification is part of a larger, transnational movement aiming to preserve or create sustainability for workers and the environment. For export-food producers in the global South, it means a fair price, fair labor conditions, direct relationships with buyers, and democracy within their organizations. In democratic South Africa, Fairtrade is linked to government-incentivized Black Economic Empowerment (BEE) initiatives. The movement is, in effect, certifying and labelling transformative programmes to economically empower members of previously disadvantaged groups. This paper explores the intersection of BEE and Fairtrade in the post-apartheid wine industry. Based on interviews with relevant stakeholders and secondary sources, it shows that the South African context has necessitated some re-negotiation of fairness, and of the role of the international Fairtrade certifier. Although Fairtrade products from South Africa are primarily sold in Europe and North America, NGOs and businesses in the global North have not simply handed down the rules, asking for compliance in return for a label, as might be expected under neoliberal globalization. Rather, the Fairtrade label on South African products means that it was produced according to South African rules that aim to promote social transformation.

La certificación de Comercio Justo hace parte de un mayor movimiento trasnacional que intenta preservar o crear sostenibilidad para trabajadores y el medio ambiente. Para los productores de alimentos para la exportación en el sur global, esto significa un precio justo, condiciones de trabajo justas, relaciones directas con sus compradores y una democracia dentro de sus organizaciones. En la democrática Sudáfrica, el Comercio Justo está ligado a las iniciativas incentivadas por el gobierno al Empoderamiento económico negro (BEE, por sus siglas en inglés). El movimiento es en efecto, la certificación y etiquetación de programas transformativos para empoderar económicamente a miembros de grupos previamente en desventaja. Este artículo explora la intersección del BEE y el Comercio Justo en la industria vitivinícola del post apartheid. En base a entrevistas con las partes interesadas y fuentes secundarias, se demuestra que el contexto sudafricano ha necesitado alguna renegociación justa, y en el rol de certificador internacional de Comercio Justo. Aunque los productos del Comercio Justo de Sudáfrica se venden primariamente en Europa y Norteamérica, las ONG y los negocios en el norte global no han transmitido las reglas, pidiendo cumplimiento a cambio de una etiqueta, como se podría esperar bajo la globalización neoliberal. Por lo contrario, la etiqueta del Comercio Justo en los productos sudafricanos, significa que fue producido de acuerdo a las reglas sudafricanas que intentan promover la transformación social.

公平贸易认证属于一场更大规模的跨国运动的组成部分,该运动旨在维持或创造工人和环境的可持续发展。对于南方国家的出口食品生产商而言,公平贸易认证意味着公平价格、公平劳动条件、与买家的直接联系和组织内部的民主。在民主国家南非,公平贸易与政府鼓励的南非黑人经济振兴政策（BEE）倡议相关。这项倡议实际上通过对变革方案的认证和分类,谋求改变从前处于弱势地位的群体成员的经济地位。本文探讨了在后种族隔离时代的葡萄酒行业中,南非黑人经济振兴政策和公平贸易的交集。根据与有关利益相关者的访谈和二手资料,本文证明了在南非的环境下,公平这一概念和国际公平贸易认证机构的作用有必要进行重新谈判。在新自由主义全球化的背景下,尽管南非的公平贸易产品主要销往欧洲和北美,北方国家的非政府组织和企业却出乎意料地没有简单地制定规则并要求南非遵守,以换取其对南非公平贸易产品的承认。相反,南非产品的公平贸易标签意味着它按照南非制定的规则进行生产,这些规则旨在促进南非的社会转型。

Geographic Migration Among Residents in Seniors Housing and Care Communities: Evidence From the Residents Financial Survey

ABSTRACT

Although the elderly as a while show relatively little geographic migration in the U.S., we were interested in the geographic migration patterns among a specific subset of elderly that we know have moved out of the traditional family home—those living in assisted living and independent living communities. We analyze data from the Residents Financial Survey, a survey of 2,617 residents in assisted living and independent living communities that asked about their previous living arrangement, where they lived before moving to their current community, and how their care needs were previously met. We find there is substantial migration among respondents. Using self-reported and community-reported location and zip code information, we calculated whether people moved across state lines and we computed the distance people moved between their previous location and their current community. While the median distance moved is less than 10 miles, 20% moved across state lines and 21% of the sample moved more than 100 miles, with the average distance moved among the sample being 165 to 190 miles. The evolution of living arrangements shows that there are strong correlations among respondents' current living arrangements, previous living arrangements, and their plan to move in the future.
