An Embattled Yet Enduring Influence: Introduction to a Special Issue on Blumerian Symbolic Interactionism

The papers in this special issue celebrate and build on the insights Blumer provides in his pivotal book Symbolic Interactionism: Perspective and Method. In setting the context for these papers, we discuss the significance of Blumer's variant of interactionism, his contributions to the discipline of sociology, the misinterpretations and misrepresentations of his approach, and the way in which the papers in this issue carry forward his legacy.     

HIV disclosure and subsequent sexual behaviors among men who have sex with men who meet online

To assess HIV disclosure discussions and related sexual behaviors among men who have sex with men (MSM) who meet sex partners online, 28 qualitative interviews with Seattle-area MSM were analyzed using grounded theory methods and themes and behavior patterns were identified. MSM found a greater ease in communicating and could prescreen partners through the Internet. However, no consistent relationship was found between HIV disclosure and subsequent behaviors: some were safer based on disclosure while perceived HIV status led others to risky behaviors. Interventions need to promote accurate disclosure while acknowledging its limitations and the need for men to self-protect.     

How a Navigation Channel Contributed to Most of the Flooding of New Orleans During Hurricane Katrina

Levee failures during Hurricane Katrina left 85% of New Orleans flooded, 1,500 dead, and about 400,000 homeless. Three separate investigations into the levee failures have been concluded, yet none of these studies conclusively determined why the St Bernard polder flooded so deeply, despite Team Louisiana’s conclusion regarding early failure of the Mississippi River Gulf Outlet (MRGO) levees. Detailed wave and hydrodynamic modeling reported here reveals the cause of extensive breaching of the MRGO levees and how that created a very efficient conduit of surge water into the heart of the city.     

Methodological challenges of designing a survey to capture young people’s (non-binary) affiliations in relationship to religion,sexuality and gender

ABSTRACT

Large-scale population studies surveying young people in relation to their worldviews have tended to frame their identities in a fixed and limited capacity while also treating the topics of religion/spirituality and sexuality/gender as discrete categories of scholarly analysis. We highlight the affordances and limitations of foregrounding fixed religious, sexual and gender-based identity categories in the process of collecting and analysing data related to the worldviews of young people. In this paper we argue the value of studying the complexities and intersections of these identities and worldviews together in one study. We do this through reference to the Australia’s Generation Z (AGZ) study: the first nationally representative sample focused on providing an evidence-based understanding of both the religious/spiritual/non-religious and sexuality/gender identities and worldviews of young Australians aged 13–18. We discuss how we built on existing surveys in designing the AGZ survey. We also demonstrate how this survey allowed for the incorporation of young people’s non-binary understandings of religion, sexuality and gender.     

The glm log-rank test:general linear modeling of log-rank scores as a method of analysis for survival data

The use of general linear modeling (GLM) procedures based on log-rank scores is proposed for the analysis of survival data and compared to standard survival analysis procedures. For the comparison of two groups, this approach performed similarly to the traditional log-rank test. In the case of more complicated designs - without ties in the survival times - the approach was only marginally less powerful than tests from proportional hazards models, and clearly less powerful than a likelihood ratio test for a fully parametric model; however, with ties in the survival time, the approach proved more powerful than tests from Cox's semi-parametric proportional hazards procedure. The method appears to provide a reasonably powerful alternative for the analysis of survival data, is easily used in complicated study designs, avoids (semi-)parametric assumptions, and is quite computationally easy and inexpensive to employ.     

How Means-Tested Transfer Programs Respond to Household Earned-Income Increases: Policy and Practice

We use data from the 2008 Survey of Income and Program Participation to estimate how four means-tested transfer programs respond to household earned-income increases. In general, the programs respond as we would expect based on the program laws and regulations, with some important exceptions, including that benefits received under some programs take much longer to fully adjust to earned-income increases than we would expect. We explore the reasons for these departures from our expectations and discuss the implications for policymakers’ efforts to balance the programs’ goals of poverty alleviation, cost effectiveness, and work promotion.     

The Role of Poverty and Chaos in the Development of Task Persistence Among Adolescents

Late adolescents (N = 256; M_age = 17.5) who spent a larger proportion of their early life in poverty exhibited less persistence when confronted by a challenging task. Greater chaos during early adolescence also predicted less task persistence at age 17. However, the effects of poverty were moderated by chaos such that if chaos levels were high during early adolescence, task persistence was uniformly lower among late adolescents, irrespective of childhood poverty. Only when chaos levels were relatively low did poverty matter for future task persistence. Furthermore, the interactive effects of chaos and early childhood poverty were independent of child ability, and of concurrent chaos and poverty.     

LETTING DOWN THE TEAM? SOCIAL EFFECTS OF TEAM INCENTIVES

This paper estimates social effects of incentivizing people in teams. In three field experiments featuring exogenous team formation and opportunities for repeated social interactions, we find large team effects that operate through social channels. In particular, assignment to a team treatment increases productivity by 9%–17% relative to an individual incentive treatment, even though the individual incentive yields a higher private return. Further, we find that in a choice treatment individuals overwhelmingly prefer the individual incentive to the team incentive, despite the latter being more effective. These results are most consistent with the team effects operating through guilt or social pressure as opposed to pure altruism.
