Aren't they just black kids? Biracial children in the child welfare system

In the USA, African‐American children are overrepresented in the child welfare system. However, little is known about the child welfare system experiences of biracial children, who are predominately both White and African‐American. To better understand this population, data from public child welfare in a US county were used to examine biracial children in the child welfare system. Results showed significant racial differences between children in the child welfare system. Despite the common belief that biracial children will have experiences similar to African‐American children, the child welfare system seems to view them differently. Biracial children are more likely to be referred, rated as high risk and investigated compared with White or African‐American children. Their mothers were younger, and were more often assessed as having physical, intellectual or emotional problems. These caregivers were also considered to have lower parenting skills and knowledge compared with White or African‐American caregivers. Although the disproportionate representation of African‐American children in the system has been well documented, this study provides evidence that biracial children are also overrepresented. Despite the fact that this is a rapidly growing population in the USA, there is little research available about biracial children and their families.

This note discusses a problem appropriate for a beginning mathematical statistics course. Four estimators of the standard deviation of a normal data source are compared using mean square error. Both the uniformly minimum variance unbiased estimator and the usual estimator are found to be inadmissible.     

Modeling the mental health service utilization decisions of university undergraduates: A discrete choice conjoint experiment

Objective: We modeled design factors influencing the intent to use a university mental health service. Participants: Between November 2012 and October 2014, 909 undergraduates participated. Method: Using a discrete choice experiment, participants chose between hypothetical campus mental health services. Results: Latent class analysis identified three segments. A Psychological/Psychiatric Service segment (45.5%) was most likely to contact campus health services delivered by psychologists or psychiatrists. An Alternative Service segment (39.3%) preferred to talk to peer-counselors who had experienced mental health problems. A Hesitant segment (15.2%) reported greater distress but seemed less intent on seeking help. They preferred services delivered by psychologists or psychiatrists. Simulations predicted that, rather than waiting for standard counseling, the Alternative Service segment would prefer immediate access to E-Mental health. The Usual Care and Hesitant segments would wait 6 months for standard counseling. Conclusions: E-Mental Health options could engage students who may not wait for standard services.     

‘A sort of whirlwind’: mapping the changing geography of Presbyterian religious observance in Ireland

Since the European Reformation and the colonisations of the sixteenth and seventeenth centuries Ireland has evolved a distinctive religious geography which had profound implications for its political development in the nineteenth and twentieth centuries, leading ultimately to the division of the island along explicitly religio–territorial lines in 1921. Troubled Geographies, a major project funded under the auspices of the Arts and Humanities Research Council's ‘Religion and Society’ programme was the first attempt to seek to understand patterns of change in the island's complex geography of religious settlement in the period since the Great Famine of the mid-nineteenth century up to the most recent published censuses for both Northern Ireland and the Republic. This paper will present findings from a smaller spin-off project funded by the British Academy, which digitised records of attendance at Presbyterian churches across the island over the last 150 years, enabling us to assess how patterns of practice were affected by the momentous events of the period, including partition, civil war, two world wars, the vicissitudes of the global economy and the Troubles of the more recent past. In addition, the use of new quantitative materials such as those in the Presbyterian records enables us to reflect on how patterns of substantive religious practice reflect those on nominal religious affiliation available from successive censuses from either side of the border.     

LEFT FOR DEAD: ANTI‐COMPETITIVE BEHAVIOR IN ORBITAL SPACE

In a dynamic investment framework with depreciation, we show incumbent satellite operators have incentives to “warehouse” a fraction of their assigned spectrum and orbital slots, keeping nonoperational assets in place, which reduces output, increases prices, and diminishes social welfare. Exploring three distinct market structures, we model firms' incentives to warehouse, and show conditions under which firms choose to warehouse rather than replace nonfunctioning satellites. We find a dominant firm with a competitive fringe produces more and longer duration warehousing relative to perfect competition or monopoly. Regulators could remediate warehousing by increasing a firm's marginal costs, or by increasing the probability of reallocating orbital slots that do not have a fully functioning satellite.

Juggling a “junk-food” diet: responses of an urban bird to fluctuating anthropogenic-food availability

Within highly urban systems, anthropogenic activity often fluctuates cyclically, e.g. between weekdays and weekends. Thus, urban species may regularly experience significant changes in human activity and anthropogenic food abundance over very short time scales. Knowledge of how urban birds cope with such fluctuations may improve our understanding of how some species exploit and thrive in urbanised habitats. In this study, we explore the consequences of highly fluctuating anthropogenic food for Red-winged Starlings Onychognathus morio at the University of Cape Town campus, South Africa. Here, high numbers of students (and therefore anthropogenic food resources) are present during weekdays in term time (high human presence “HHP” days). However, students are largely absent and food outlets closed during weekends and vacation periods (“LHP” days). Using focal observations and morning and evening weights of habituated colour-ringed starlings during the non-breeding season, we investigated how diet, behaviour and daily mass gain differed between HHP and LHP days. We hypothesised that anthropogenic food supply is beneficial to this city-dwelling species. We predicted that on HHP days starlings would consume overall more food and a greater proportion of anthropogenic food items, resulting in less time spent foraging and greater daily mass gain compared to LHP days. We found that on HHP days, starlings consumed more anthropogenic food, however overall food intake, and time budgets were similar to LHP days. Additionally, there was an indication that mass gain was greater on HHP days. Thus, starlings appear to cope with potential food shortage on LHP days by including more natural items in their diet.

     

Negotiated Project Engagements: Learning from Experience

How far is it possible to capture the lessons tobe drawn from successive projects that involveintervention by social scientists within or betweenorganizations, whether acting as researchers, asconsultants, as agents of change, or in some combination ofthese roles? This paper outlines the way in which aframework was developed, by staff and associates of TheTavistock Institute, for examining the varied and often subtle influences of successive“negotiated project engagements” on thedevelopment of wider personal, institutional, anddisciplinary programs. This framework is designed totake into account the contrasting perspectives of the investigatorsthemselves, of their organizational hosts, and of anyexternal sponsors whose primary concern will normally bewith project outcomes at a more generalized level. As an illustration, particular reference ismade to the experience of a pioneering project concernedwith policy-making in city government. This project wasundertaken to advance the understanding and practice of public planning, while also exploring thepotential for synergy between the perspectives ofoperational research and applied social science. Thepaper concludes with some speculations about thepotential for further developing this kind of frameworkin supporting experiential learning.     

Transnational politics at the edges of sovereignty: social movements,crossings and the state at the US–Mexico border

This article documents the history of border crossings among a group of social movement activists located in southern Arizona. By comparing two types of US–Mexico border crossings separated ten years apart, the article explores how political groups become ‘transnationalized’ and in relation to what kinds of ‘states’. By contrasting the shift from a state‐centric movement to a transnational coalition, the case study analyses why, in the later period, political activists were no longer able to identify the same kind of state. In chronicling the disappearance of one kind of state formation and the emergence of a transnational one, this research argues that globalization—rather than simply reflecting a decline of the nation state—is a process entailing not only new forms of transnational political activism but also new forms of the state.     

Becoming independent: political participation and youth transitions in the Scottish referendum

Sociological debates on youth engagement with electoral politics play out against a backdrop of supposed ‘decline’ in civic participation (e.g. Putnam 2000 , Norris, 2011 ), in turn contextualized by theories of individualization in ‘late’ or ‘reflexive’ modernity (Beck, Giddens). However, the enfranchisement of 16 and 17 year olds in the 2014 Scottish Independence Referendum catalysed remarkably high levels of voter turnout among this youngest group, and was accompanied by apparently ongoing political engagement. We explored this engagement among a strategic sample of young ‘Yes’ voters, in the immediate aftermath of this exceptional political event. Analysis of qualitative interview data generated an unanticipated finding; that interviewees narrated their political engagement biographically, articulated their referendum participation reflexively, and located their new political ideas, allegiances and actions in the context of their own transitions to ‘independent’ adulthood. This inspired us to rethink young people's political engagement in relation to youth transitions. Doing so enables a synthesis of divergent strands in the sociology of youth, and offers new insights into the combinations of ‘personal’ agentic and ‘political’ structural factors involved in young people's politicization.     

Age‐Specific Associations Between Violence Exposure and Past 30‐Day Marijuana and Alcohol Use

Using data from a cohort study of students at risk for high school dropout, we examined associations between violence exposure and past 30‐day alcohol and marijuana use. We used varying‐coefficient regression with person‐level fixed effects to estimate how those associations changed within‐person across ages approximately 14–23. Generally, violence perpetration was most strongly associated with substance use, within‐person. Substance use became increasingly associated with both observed violence and violence perpetration during early/middle adolescence; this increase continued longer into development (age 18+) for alcohol use. Across most of the age range studied here, violence victimization was minimally associated with within‐person changes in substance use. Results indicate age‐specific associations between violence exposure and alcohol and other drug use, which may be useful for informing prevention strategies.
