Pollen specialization by solitary bees in an urban landscape

Many polylectic bee species are known to specialize locally on one or a few pollen types to increase foraging efficiency. What is relatively unknown is how different landscapes influence foraging decisions, and whether habitat alteration, such as that resulting from urbanization, influences broad-scale foraging activities of bees. This study evaluates the type and diversity of pollen collected by two solitary bees that are common in Toronto, Ontario, Canada, the native Osmia pumila and the exotic O. caerulescens, sampled in trap nests set up in urban parks and gardens. We found that the dominant pollen in every successful brood cell was either of one widespread, cosmopolitan lawn-invasive plant species (Trifolium repens) or one of two wind-pollinated tree genera (Quercus spp. and Betula spp.). In combination, these three represented more than 90 % of all pollen collected by each bee species. Despite considerable overlap in the dominant pollen types collected by each bee species, the exotic O. caerulescens was significantly more specialized than the native O. pumila. Brood cells with Betula as the dominant pollen type were more pollen species-rich than those cells having Trifolium or Quercus as dominant, perhaps a result of the comparatively low protein content in Betula pollen.     

The Contextual Experiences of Rural Custodial Grandparents and Opportunities for Social Work

Rural custodial grandparents have been understudied. As the grandparent caregiving population increases, more attention is needed to understand custodial grandparents in rural settings. This article explores the state of knowledge of the experiences of rural grandparents. A systematic review of the caregiving literature is conducted to understand the issues affecting this caregiving population. The results suggest that rural grandparents often are minority grandmothers with limited resources who provide care to older grandchildren in isolated environments. Attention is given to the social ecological framework as one model that can help to inform how social workers intervene with this population. Recommendations are offered for social work research, practice, and policy.     

Continuity of Mental Health Care Across Military Transitions

Multiple deployments, a prominent characteristic of operations Enduring Freedom, Iraqi Freedom, and New Dawn, have been linked to increased risk for various mental health conditions. It is also well known that military transitions, such as a change of duty station or discharge, are an inevitable part of military life. While military transitions can be stressful for any service member or veteran, those with mental health conditions face additional challenges. Transition stress can exacerbate a mental health condition that in turn hinders ability to manage the transition, resulting in a cycle of stress. As a result, those receiving mental health care while transitioning often experience difficulty continuing treatment post-transition. This article describes a unique and innovative transition coaching program designed to address this emerging issue.     

Barriers to Integrated Treatment of Substance Abuse and Trauma Among Women

Despite increasing empirical support for an integrated approach to treating trauma and substance abuse, many substance abuse treatment programs have been slow to embrace integrated models of practice. Using an embedded case study design, the purpose of this study was to understand barriers that prevented a substance abuse treatment provider and 20 professionals and staff from adopting an integrated approach to treating substance abuse and trauma. Data analysis revealed 2 kinds of barriers that prevented substance abuse treatment professionals from fully integrating substance abuse and trauma: systemic and professional barriers. These barriers have to be taken into account when trying to move providers and professionals toward integrated approaches to treating substance abuse and trauma.     

A Qualitative Study of Middle Eastern/Arab American Sexual Minority Identity Development

The development of one's sexual minority identity is often stunted by a heterosexist society. For individuals with multiple minority oppressions, this process becomes even more complicated. As such, there has been a call among researchers for more empirical research on the experiences of lesbian, gay, bisexual (LGB) individuals from racial/ethnic minority groups. This study uses qualitative methods to fill gaps in the literature related to identity development among same-gender attracted Middle Eastern/Arab individuals living in the United States. From 12 interviews, 13 themes associated with intersectionality, race/ethnicity, sexual identity development, discrimination, stigma, oppression, and invisibility. Themes, subthemes, and their implications are discussed.     

Die Eliminationsmethode – Förderung kreativer Ideen durch die Elimination bekannter Lösungen

This pilot study presents the first implementation and evaluation of a new technique to raise creative performances by eliminating common ideas and conventional solutions in a first step and subsequently generate new ideas. This technique is termed “elimination method”. The experiment of this study was conducted with individually working subjects, not involving group interaction. 30 subjects worked on a creativity task with the elimination method, 30 subjects worked on the same creativity task with brainstorming technique instructions. They produced 1919 ideas which could be summarized to 268 different cognitive elements as the baseline of the research. The theoretical focus of this study is to highlight the role of common knowledge in group discussion and the corresponding intra-individual processes and cognitive processes. Overall results of data examination were in line with expectations and support future testing of the proposed elimination method in a group context. This study was able to show that the instructions for the elimination method induced effects as intended, producing mainly common ideas in the first step and mainly new ideas in the second step, overall resembling the output of the brainstorming condition. The second step of the elimination method outperformed the brainstorming condition in producing idea output with a higher creative density and one-tailed differences were significant (p? =? 0.028). Furthermore, interactions between method and creativity measures were explored. Findings were connected to corresponding research where appropriate and implications for future research were remarked upon.     

Portuguese Scientists’ Migration: a study on the 2008 crisis aftermath

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision.     

Familism Values,Family Time,and Mexican‐Origin Young Adults' Depressive Symptoms

Using longitudinal data across eight years, this study examined how parents' familism values in early adolescence predicted youths' depressive symptoms in young adulthood via youths' familism values and family time. We examined these processes among 246 Mexican‐origin families using interview and phone‐diary data. Findings revealed that fathers' familism values predicted male and female youths' familism values in middle adolescence. For female youth only, fathers' familism values also predicted youths' family time in late adolescence. The link between family time and young adults' depressive symptoms depended on parental acceptance and adolescent gender: Among female and male youth, family time predicted fewer depressive symptoms, but only when paternal acceptance was high. For female adolescents only, family time predicted fewer depressive symptoms when maternal acceptance was high but more depressive symptoms when maternal acceptance was low. Findings highlight family dynamics as the mechanisms through which familism values have implications for youths' adjustment.     

Wer ist in Deutschland willkommen?Who is welcome in Germany?

Germany is currently experiencing a huge inflow of migrants. In this vignette study, we analyze how much different kinds of migrants are accepted in Germany. We investigate three different rights for migrants: the right to stay in Germany, the right to work in Germany and the right to receive social benefits. Our results show that people who flee from political persecution are much more accepted compared to migrants who come because of economic reasons. This is particularly true for the right to receive social benefits. On the other hand, our results suggest that there is a strong preference for high-skilled and culturally non-distant migrants. Concerns regarding individual competition on the job market seem to play only a minor role.     

Inferences About Sexual Orientation: The Roles of Stereotypes,Faces, and The Gaydar Myth

In the present work, we investigated the pop cultural idea that people have a sixth sense, called “gaydar,” to detect who is gay. We propose that “gaydar” is an alternate label for using stereotypes to infer orientation (e.g., inferring that fashionable men are gay). Another account, however, argues that people possess a facial perception process that enables them to identify sexual orientation from facial structure. We report five experiments testing these accounts. Participants made gay-or-straight judgments about fictional targets that were constructed using experimentally manipulated stereotypic cues and real gay/straight people's face cues. These studies revealed that orientation is not visible from the face—purportedly “face-based” gaydar arises from a third-variable confound. People do, however, readily infer orientation from stereotypic attributes (e.g., fashion, career). Furthermore, the folk concept of gaydar serves as a legitimizing myth: Compared to a control group, people stereotyped more often when led to believe in gaydar, whereas people stereotyped less when told gaydar is an alternate label for stereotyping. Discussion focuses on the implications of the gaydar myth and why, contrary to some prior claims, stereotyping is highly unlikely to result in accurate judgments about orientation.
