Assessing the contribution of fallen autumn leaves to airborne fungi in an urban environment

Urban Ecosystems - Many street trees in urban areas are deciduous and drop leaves during autumn. These leaves are a potential growing substrate for fungi, which when aerosolized and inhaled, can...     

Young people negotiating and maintaining boundaries in youth work relationships: findings from an ethnographic study of youth clubs

‘Professional boundaries’ set limits on appropriate behaviours in the relationship between the service users and practitioners. The professional literature often assumes boundaries are maintained by the practitioners, occupational bodies, or organisational policy. However in youth work this is under-researched. An ethnographic study of four youth clubs in the North East of England into ethical practice revealed that young people were surprisingly adept at maintaining boundaries with the youth workers. These boundaries were negotiated and maintained through the young people's use of space, their willingness to interact with the workers, the way they shared information with the workers, and their inclusion of youth workers into their social networking. Young people also showed a sophisticated awareness of the organisational boundaries youth workers were operating within, and often cooperated in maintaining them with the worker. The article concludes by arguing youth workers should take seriously young people's ability and willingness to set and work within boundaries, and see their negotiation and maintenance as a mutual endeavour. However, this may provide a challenge to organisations with rigid policy-defined boundaries.     

Marital Status and Problem Gambling Among Australian Older Adults: The Mediating Role of Loneliness

Problem gambling rates in older adults have risen dramatically in recent years and require further investigation. Limited available research has suggested that social needs may motivate gambling and hence problem gambling in older adults. Un-partnered older adults may be at greater risk of problem gambling than those with a partner. The current study explored whether loneliness mediated the marital status–problem gambling relationship, and whether gender moderated the mediation model. It was hypothesised that the relationship between being un-partnered and higher levels of loneliness would be stronger for older men than older women. A community sample of Australian men (n = 92) and women (n = 91) gamblers aged from 60 to 90 years (M = 69.75, SD = 7.28) completed the UCLA Loneliness Scale and the Problem Gambling Severity Index. The results supported the moderated mediation model, with loneliness mediating the relationship between marital status and problem gambling for older men but not for older women. It appears that felt loneliness is an important predictor of problem gambling in older adults, and that meeting the social and emotional needs of un-partnered men is important.     

It is risky business: can social capital reduce risk-taking behaviours among disadvantaged youth?

This study addresses the gap in the research for sound multidimensional assessment of social capital and its relationship with risk-taking behaviour among youths living in disadvantaged communities. Social capital and adolescent risk-taking outcomes were studied cross-sectionally in 1371 secondary students living in two disadvantaged communities within Australia. First, a multidimensional measure of social capital was developed and tested using confirmatory factor analysis. Then, the associations between social capital and a range of youth risk-taking behaviours were examined using structural equation modelling across five-year groups (Grades 7–12). With a few exceptions, higher levels of social capital and belongingness within the school and community were generally associated with decreases in smoking, alcohol and drug consumption, and physical violence. Some outcomes were more strongly associated with family and peer social capital, while others associated more with neighbour and community social capital, indicating that attempts to build social capital need to be targeted across the whole community. This study supports the notion that social capital can be measured empirically and is beneficial in alleviating many of the detrimental health outcomes commonly associated with risk-taking behaviours during adolescence.     

Defining Women's Global Political Empowerment: Theories and Evidence

Although women's access to political power has increased tremendously, nowhere are women equal to men in their influence over and exercise of political authority. Scholarship on women's political empowerment is uneven and incomplete. This article interrogates ‘women's political empowerment’, considering its definition, measurement, and application. First, we establish that academics and practitioners have not articulated a clear definition of women's political empowerment. To fill this gap, we put forward a new definition that conceptualizes women's political empowerment as a transformative process. We then review existing social science literature on women's political empowerment. We argue that scholars must expand research to develop a broader vision of women's political empowerment and develop measures that capture this breadth.     

Soziale Beeinflussung in Mikronetzwerken am Beispiel der Erhebung von Markenpräferenzen mit dem „Tischmodell“

Brand preferences in a homogeneous student milieu are analyzed in order to model how social influence affects people’s views and opinions. In this study the individual person is not considered as unit of analysis, but rather the people eating together at a table in a canteen. In classical surveys the opinions of the respondents should be independent from one another. In contrast to standard surveys the study presented here explicitly aims to examine the influence of a micro network on the attitudes of the constituent actors. To measure this effect an overall degree of conformity is calculated based on all table communities. Simulations are used to estimate the influence of the relations constituting the table community on the agreement of brand preferences among the table companions. Similar to the well-known bootstrapping procedure, the respondents are randomly grouped into table communities, where the distribution of group sizes matches the observed distribution for every resampling. By controlling for the socio-demographic structure of the table communities it is possible to estimate the effect of the micro-networks on the agreement of brand preferences. It turns out that the relevance of the “network effect” remains, even if the distribution of socio-demographic factors such as age, gender and field of study were held constant within the table communities. The presented “table model” can be applied to many problems.     

Disparities in socio-economic outcomes: some positive propositions and their normative implications

Demographic disparities between the rates of occurrence of an adverse economic outcome can be observed to be increasing even as general social improvements supposedly lead towards the elimination of the adverse outcome in question. Scanlan (Chance 19(2):47–51, 2006) noticed this tendency and developed a ‘heuristic rule’ to explain it. In this paper, we explore the issue analytically, providing a criterion from stochastic ordering theory under which one of two demographic groups can be considered disadvantaged and the other advantaged, and showing that Scanlan’s heuristic obtains as a rigorous finding in such cases. Normative implications and appropriate social policy are discussed.     

Personality at Face Value: Facial Appearance Predicts Self and Other Personality Judgments among Strangers and Spouses

Character judgments, based on facial appearance, impact both perceivers’ and targets’ interpersonal decisions and behaviors. Nonetheless, the resilience of such effects in the face of longer acquaintanceship duration is yet to be determined. To address this question, we had 51 elderly long-term married couples complete self and informant versions of a Big Five Inventory. Participants were also photographed, while they were requested to maintain an emotionally neutral expression. A subset of the initial sample completed a shortened version of the Big Five Inventory in response to the pictures of other opposite sex participants (with whom they were unacquainted). Oosterhof and Todorov’s (in Proc Natl Acad Sci USA 105:11087–11092, 2008) computer-based model of face evaluation was used to generate facial trait scores on trustworthiness, dominance, and attractiveness, based on participants’ photographs. Results revealed that structural facial characteristics, suggestive of greater trustworthiness, predicted positively biased, global informant evaluations of a target’s personality, among both spouses and strangers. Among spouses, this effect was impervious to marriage length. There was also evidence suggestive of a Dorian Gray effect on personality, since facial trustworthiness predicted not only spousal and stranger, but also self-ratings of extraversion. Unexpectedly, though, follow-up analyses revealed that (low) facial dominance, rather than (high) trustworthiness, was the strongest predictor of self-rated extraversion. Our present findings suggest that subtle emotional cues, embedded in the structure of emotionally neutral faces, exert long-lasting effects on personality judgments even among very well-acquainted targets and perceivers.     

Cracking the Code—An Approach to Developing Professional Writing Skills

The development of writing skills sufficient to meet the complexities of contemporary social work practice is a growing demand from employers and practice educators. The paper explores current pedagogical debate relating to student support and the development of writing skills and relates this debate to meeting the needs of social work students engaged in practice learning and professional practice. A number of questions are raised about current social work education in England and the needs of students entering from non-traditional academic backgrounds facing the increasingly rigorous demands of professional report writing. The discussion is then grounded in a practice example of staff from a university social work course and education guidance service working together to meet student need in respect of developing writing skills. The development, implementation and evaluation of a university writing skills programme for social work students are explored. The paper concludes by setting out a range of challenges arising from experience of the programme and a consideration of theory, and points to potential ways forward based on a social practice approach to teaching writing skills.     

Career Engagement: Investigating Intraindividual Predictors of Weekly Fluctuations in Proactive Career Behaviors

This study applied a microlevel perspective on how within‐individual differences in motivational and social‐cognitive factors affected the weekly fluctuations of engagement in proactive career behaviors among a group of 67 German university students. Career self‐efficacy beliefs, perceived career barriers, experienced social career support, positive and negative emotions, and career engagement were assessed weekly for 13 consecutive weeks. Hierarchical linear regression analyses showed that above average levels of career engagement within individuals were predicted by higher than average perceived social support and positive emotions during a given week. Conversely, within‐individual differences in self‐efficacy, barriers, and negative emotions had no effect. The results suggest that career interventions should provide boosts in social support and positive emotions.
