The effect of urban ground covers on arthropods: An experiment

Changes to the ground layer in urban areas are extensive, but the effects on arthropod fauna are poorly understood. We undertook a manipulative experiment to examine the response of arthropods to small-scale variation in ground covers commonly found in urban parks and gardens in Australia. The ground covers tested were bare ground, leaf litter, woodchips and grass, with plot sizes of 3.6 m². Epigeic arthropods were sampled with pitfall traps and Tullgren funnels over 12 months following establishment of the treatments. All epigeic arthropods were sorted to order and the ants (Hymenoptera: Formicidae), beetles (Coleoptera), millipedes (Diplopoda) and slaters (Isopoda: Oniscidea) were examined at lower taxonomic levels. Diverse arthropods rapidly colonised previously cleared plots in all four treatments and were most abundant in grass plots. The diversity of ants and beetles was significantly different in different ground covers and tended to be most diverse in grass plots. Despite the treatments providing very different microclimates, the fauna studied did not show strong selection for a particular cover type overall. The abundance of grass cover in the surrounding area may have led to the grass plots having the greatest abundance of arthropods. These results have important implications for developing effective small-scale conservation efforts for arthropods in anthropogenically modified landscapes, especially for species with poor dispersal abilities.     

The Interactional Construction of Social Authenticity: “Real” Identities and Intergroup Relations in a Transylvania Internet Forum

Authenticity has become an increasingly salient topic within various interactional traditions, including conversational and discourse analysis, discursive psychology, interactional sociolinguistics, pragmatics, and symbolic interactionism. However, there has been remarkably little cross‐fertilization of ideas and concepts. In this study, we consider the relevance of the interactional sociolinguistic concept of relationality for symbolic interactionist theories of authenticity. We first disambiguate two forms of authenticity that are commonly studied but not clearly differentiated in symbolic interactionist research—self‐authenticity, which emphasizes selves, and social authenticity, which emphasizes social identities. We then argue that relationality and its three pairs of interactional tactics—verification and denaturalization, adequation and distinction, and authorization and illegitimation—are particularly useful in conceptualizing social authenticity. We draw on data from an interethnic internet forum to show how members of two ethnic groups, Hungarian and Romanian, employ these relational tactics to authenticate their own ethnicity as the rightful inheritors of a place‐based Transylvanian identity, and to limit the other ethnicity's similar identity work. We then clarify the significance of social authenticity for the interactional study of category‐based identities by widening our discussion to other contestations over social identities in everyday life.     

I got all my sisters with me (on Black Twitter): second screening of How to Get Away with Murder as a discourse on Black Womanhood

ABSTRACT

In addition to performing racial identity on Black Twitter, Black users also use the platform to host discourse on Blackness. Tweets, hashtags, and trends associated with the television show How to Get Away with Murder are used to demonstrate that second screening and co-viewing of the series on Twitter enables a technocultural discourse on a shared cultural history of Black womanhood. Specifically, we address scenes portrayed in HTGAWM and highlight the intersection of race and gender. From a critical Black feminist lens we analyze the response on Black Twitter.     

A Preliminary Report on the Relationship Between Microaggressions Against Black People and Racism Among White College Students

Previous efforts to understand microaggressions have surveyed stigmatized group members’ experiences of receiving microaggressions. This report presents the first attempt to measure self-reported likelihood of delivering microaggressions rather than receiving microaggressions and to explore the association between the likelihood of delivering microaggressions and racial prejudice. We conducted a cross-sectional survey of 33 black and 118 non-Hispanic white undergraduate students at a large public Southern/Midwest university. Black students reported the degree to which a series of statements would be experienced as microaggressive. White students reported their likelihood of delivering those statements and completed measures of racial prejudice. White students’ self-reported likelihood of engaging in microaggressive acts was significantly related to all measures of racial prejudice. The single item “A lot of minorities are too sensitive” was the strongest predictor of negative feelings toward black people. Results offer preliminary support that the delivery of microaggressions by white students is not simply innocuous behavior and may be indicative of broad, complex, and negative racial attitudes and explicit underlying hostility and negative feelings toward black students.     

Quantitative Risk Assessment of Norovirus Transmission in Food Establishments: Evaluating the Impact of Intervention Strategies and Food Employee Behavior on the Risk Associated with Norovirus in Foods

We developed a quantitative risk assessment model using a discrete event framework to quantify and study the risk associated with norovirus transmission to consumers through food contaminated by infected food employees in a retail food setting. This study focused on the impact of ill food workers experiencing symptoms of diarrhea and vomiting and potential control measures for the transmission of norovirus to foods. The model examined the behavior of food employees regarding exclusion from work while ill and after symptom resolution and preventive measures limiting food contamination during preparation. The mean numbers of infected customers estimated for 21 scenarios were compared to the estimate for a baseline scenario representing current practices. Results show that prevention strategies examined could not prevent norovirus transmission to food when a symptomatic employee was present in the food establishment. Compliance with exclusion from work of symptomatic food employees is thus critical, with an estimated range of 75–226% of the baseline mean for full to no compliance, respectively. Results also suggest that efficient handwashing, handwashing frequency associated with gloving compliance, and elimination of contact between hands, faucets, and door handles in restrooms reduced the mean number of infected customers to 58%, 62%, and 75% of the baseline, respectively. This study provides quantitative data to evaluate the relative efficacy of policy and practices at retail to reduce norovirus illnesses and provides new insights into the interactions and interplay of prevention strategies and compliance in reducing transmission of foodborne norovirus.     

A meta-analytic review and future research agenda of charismatic leadership

Charismatic leadership is a critical construct that draws much attention from both academic and practitioner literatures. Despite the positive attention received by the charisma construct, some have criticized its conceptualization and measurement. These critiques have, in turn, cast doubt on what we know regarding the antecedents and outcomes of charismatic leadership. In this review, we adopt a recently developed definition of charismatic leadership and then conduct a meta-analysis of its antecedents and objective outcomes. Following an examination of 76 independent studies and 36,031 individuals, results indicate that the Big Five traits and cognitive ability vary in their association with charismatic leadership. Other findings show that dimensions of charismatic leadership predict outcomes of interest, such as supervisor-rated task performance, supervisor-rated citizenship behaviors, and group or organization performance. Several shortcomings are identified, however, in testing theoretical and methodological moderating variables. The present research ultimately provides a roadmap for new frontiers in theoretical, measurement and empirical work on charismatic leadership.     

The interactive effects of political skill and future time perspective on career and community networking behavior

Scholars have suggested that skill (Ferris et al., 2007) and motivation (Forret and Dougherty, 2001) need to be considered in predicting the direction and intensity of networking behaviors. Congruently, the present study argues that skill and motivation operate interactively and assesses the interactive impact of political skill (i.e., the ability to interact effectively with others) and future time perspective on differentially predicting community-based and career-based networking behavior. Results from a sample of managers from a national retail chain (n = 291) indicated that politically skilled individuals who possessed a deep future time perspective were more involved in career-related networking than politically skilled individuals who perceived a shallow future time perspective. Additionally, politically skilled respondents with shallow organizational time perspectives engaged in higher levels of community-based networking than did their counterparts with deeper organizational time perspectives. The implications of these findings are discussed in terms of political skill, social networks, and socioemotional selectivity theory.
