The Assets Coming Together for Youth project conducted a critical discourse analysis of mainstream media depictions of Jane-Finch to better understand the discursive strategies used to constitute urban youth. Although a substantive body of literature investigates the negative discourses, little analysis interrogates the nominally positive discourses deployed by mainstream media. The findings suggest that the sociopolitical significance of these nominally positive discourses may go uncontested and pose a challenge to communities advocating for policies to support urban youth development. These discourses are examined using governmentality theory to reveal how racialized narratives of individual triumph re/produce troubled communities. 相似文献

The current analysis was designed to critically examine the tendency to focus on child maltreatment as a unique risk factor and test the resulting assumption of a direct causal relationship between early maltreatment and later behavioral problems. The variation seen in behavioral outcomes among children reported for maltreatment early in life led us to hypothesize that the cumulative level of risk facing children and their families can, at least in part, account for that variation in outcome. Participants were 242 mothers of predominantly at-risk newborn infants who were interviewed shortly after giving birth. The State Central Registry of Maltreatment was then reviewed over each child's first four years of life to assess for early maltreatment. Following the neonatal interviews, mothers completed the Child Behavior Checklist when their children were 4, 6, 8, 10 and 12 years-of-age. Although early maltreatment report does appear to be important to early child functioning, the cumulative level of risk more strongly predicts long-term clinical behavioral difficulty. High-risk children who were not reported for maltreatment by age 4 demonstrate greater behavioral problem trajectories than did low-risk children with a maltreatment report. Maltreatment itself may be best conceptualized as an important, but not singularly so, risk factor for later behavioral problems. In focusing directly on reported maltreatment, our child protective systems may be paying too little attention to what else is going wrong in the lives of children and targeting intervention efforts in the wrong direction. When it comes to early maltreatment our child protective policy and practice need to broaden their lenses to include greater emphasis on overall family functioning, stress and well-being. Early maltreatment, it seems, may be a symptom of more profound problems in the early environments of our most vulnerable children, rather than the problem itself. 相似文献

Scholars in a number of disciplines have sought to assess the power of reading or viewing a personal story to modify people's beliefs. However, the research, which has been pursued under diverse programs, has produced conflicting findings. We focus on the persuasiveness of personal stories about problems that are structural (rather than individual) and whose solution requires government action. Overall, the research suggests that although personal stories can overcome people's tendency to resist new information, they often do not do so. People's preexisting beliefs, assumptions, and stereotypes affect their willingness to be absorbed by a story, to empathize with the stories' protagonists, and to endorse the message communicated by the story. We argue also for a sociological perspective on narrative persuasion, one which, unlike the mostly experimental research conducted so far, pays attention to the context in which people encounter stories and to the norms shaping people's assessment of a story as credible, relevant, and important. 相似文献

Leveraging historical data into the design and analysis of phase 2 randomized controlled trials can improve efficiency of drug development programs. Such approaches can reduce sample size without loss of power. Potential issues arise when the current control arm is inconsistent with historical data, which may lead to biased estimates of treatment efficacy, loss of power, or inflated type 1 error. Consideration as to how to borrow historical information is important, and in particular, adjustment for prognostic factors should be considered. This paper will illustrate two motivating case studies of oncology Bayesian augmented control (BAC) trials. In the first example, a glioblastoma study, an informative prior was used for the control arm hazard rate. Sample size savings were 15% to 20% by using a BAC design. In the second example, a pancreatic cancer study, a hierarchical model borrowing method was used, which enabled the extent of borrowing to be determined by consistency of observed study data with historical studies. Supporting Bayesian analyses also adjusted for prognostic factors. Incorporating historical data via Bayesian trial design can provide sample size savings, reduce study duration, and enable a more scientific approach to development of novel therapies by avoiding excess recruitment to a control arm. Various sensitivity analyses are necessary to interpret results. Current industry efforts for data transparency have meaningful implications for access to patient‐level historical data, which, while not critical, is helpful to adjust for potential imbalances in prognostic factors. 相似文献

Objectives. The competitiveness of the 2008 presidential primaries in both the Republican and Democratic parties has prompted a reconsideration of the role of delegate‐selection rules in influencing the strategic behavior of presidential candidates. Using advertising and candidate state‐visit data from the 2004 and 2008 presidential nominating campaigns, we reexamine the strategies presidential candidates use when competing for the nomination of their party. Methods. Using the Wisconsin Advertising Project Data from 2004 and 2008, we estimate several multiple regressions designed to analyze the factors predicting candidate visits and advertising. Results. We find that, to a large extent, the rules of the game help predict where candidates allocate their political advertising and campaign stops; candidates consider whether a contest is a primary or caucus, they pay attention to how many delegates are at stake, and they consider whether a state's delegate‐allocation method is largely proportional or winner take all. Yet we also find some differences in how the rules influence frontrunners and long‐shot candidates, and we discover how other factors, including a candidate's access to financial resources, influence the allocation of ads and visits. Conclusion. Our findings offer some of the first empirical evidence for the idea that a state's delegate‐allocation method influences candidates' resource‐allocation behavior. That these rules matter at all is somewhat of a surprise given that the delegate‐allocation methods used by states have become more homogenous within each party. 相似文献

This article describes the use of comics in a mixed methods biographical research project aimed at understanding the experiences of vegans (i.e. people who eschew animal products such as meat, dairy and eggs). It begins with a discussion of Comics Studies as a growing interdisciplinary field of academic inquiry, and attempts to trace a connection between this and Visual Sociology more broadly. It then provides examples of the way in which comics were used in the project and the rationale underpinning this. Participants were asked to create comics about their lives, which aimed to supplement biographical interviews that had already taken place, eliciting rich ‘visual biographical’ data that an interview would not produce. Comics were also used as a mode of representation, whereby a ‘visual autoethnography’ was produced, outlining the author’s reflexive autobiographical relationship with veganism, and telling the story of the research. This project presented challenges, specifically around participation, ethics and anonymity, and data analysis. Despite this, the comics produced provided an unusual and valuable insight into the lives and experiences of vegans. To conclude, this article argues that the visual biographical data yielded through the use of the Comics medium represents a valuable tool in visual sociology. 相似文献
