CHANGING PRACTICES AND CONCEPTIONS OF THE EXECUTIVE FUNCTION IN URBAN GOVERNMENT: THE GREATER BRISBANE EXPERIENCE

Abstract: Since the commencement of the Greater Brisbane scheme in 1925, a number of different ways of organising the executive function have been provided for in the legislation. These have included a mayor elected at large as chief executive officer; an appointed city manager model, which was never activated; a quasi-cabinet model, with the mayor being elected by the council rather than at large; a "weak" collective executive committee, akin to the early 20th century "board of control" arrangements in Canada, the mayor being elected at large and standing committees of council possessing substantial policy formulation powers; a stronger collective executive in theory, alongside which something akin to the American "strong mayor with chief administrative officer" model operated in practice; a strong collective executive, with the mayor once again elected indirectly, and weak standing committees of aldermen retained; a return to something like the original mayor-as-CEO arrangement; and finally, a strengthened version of the initial "mayor-as-CEO with chief administrative officer" model. These changes are traced chronologically and a general assessment is offered in conclusion.

Clear and Present Strangers: The Clash of Civilizations and International Conflict

Huntington's (1993a, 1993b, 1996) clash of civilizations thesis suggests that states belonging to different civilizations are more likely to become involved in conflict with one another. To evaluate the empirical accuracy of Huntington's claims, we examined the relationship between civilization membership and interstate war between 1816 and 1992. We find that civilization membership was not significantly associated with the onset of interstate war during the Cold War era (1946–1988), which is consistent with one aspect of Huntington's thesis; however, we also find that for the pre–Cold War period (1816–1945) states of similar civilizations were more likely to fight each other than were those of different civilizations, which contradicts Huntington's thesis. Most importantly, our analysis reveals that during the post–Cold War era (1989–1992), the period in which Huntington contends that the clash of civilizations should be most apparent, civilization membership was not significantly associated with the probability of interstate war. All told, our findings challenge Huntington's claims and seriously undermine the policy recommendations that devolve from his clash of civilizations thesis.     

CustomNegotiations.org: A Free Resource for Creating Custom Negotiation Simulations

Negotiation role‐playing simulations are among the most effective and widely used methods for teaching and conducting research on negotiations. Teachers and researchers can either license a published, “off‐the‐shelf” simulation or write their own custom “bespoke” simulation. Off‐the‐shelf simulations are usually high‐quality, include teaching materials, and are typically priced affordably, whereas bespoke simulations are fully customizable and ensure that participants will face a novel challenge. In this article, I introduce a third option: CustomNegotiations.org, a free resource for creating custom negotiation simulations that have the benefits of both off‐the‐shelf and bespoke simulations. I describe this resource and preview how negotiation instructors can use it to customize simulations for their own classes. I also discuss possible future directions for this kind of platform.     

How Accurate Are Survey Responses on Social Media and Politics?

How accurate are survey-based measures of social media use, in particular about political topics? We answer this question by linking original survey data collected during the U.S. 2016 election campaign with respondents’ observed social media activity. We use supervised machine learning to classify whether these Twitter and Facebook account data are content related to politics. We then benchmark our survey measures on frequency of posting about politics and the number of political figures followed. We find that, on average, our self-reported survey measures tend to correlate with observed social media activity. At the same time, we also find a worrying amount of individual-level discrepancy and problems related to extreme outliers. Our recommendations are twofold. The first is for survey questions about social media use to provide respondents with options covering a wider range of activity, especially in the long tail. The second is for survey questions to include specific content and anchors defining what it means for a post to be “about politics.”     

Sexual Debut Timing and Depressive Symptoms in Emerging Adulthood

The association between sexual debut timing and depressive symptomatology in adolescence and emerging adulthood was examined using data from Waves I, II and III of the National Longitudinal Study of Adolescent Health. Respondents who reported never having sexual intercourse at Wave I and were 18–22 years of age at Wave III were included (n = 5,061). Twenty percent of respondents experienced early (<age 16) and 49% experienced typical (ages 16–18) sexual debut. In bivariate analyses, pre-debut depressive symptoms were associated with earlier sexual debut among female but not male adolescents. In models adjusting for demographic characteristics and pre-debut depressive symptoms, sexual debut was positively related to adolescent (Wave II) depressive symptomatology, but only among female adolescents age less than sixteen. However, sexual debut timing was unassociated with emerging adult (Wave III) depressive symptomatology for both male and female respondents. Findings suggest sexual debut timing does not have implications for depressive symptomatology beyond adolescence.

Advice about Life Plans from Mothers,Fathers, and Siblings in Always-Married and Divorced Families during Late Adolescence

The frequency of advice about life plans that older adolescents in always-married and divorced families received from mothers, fathers, and siblings was examined. Also, a pattern-analytic approach that grouped adolescents according to the amount of advice about life plans received from each parent and a sibling was employed to explore the connections between patterns of advice and adolescents' future occupational, educational, and family plans. The sample included 544 and 95 older adolescents in always-married and divorced families, respectively. Findings suggested that while adolescents relied on mothers for advice in both always-married and divorced families, adolescents in divorced families depended on fathers and siblings for advice less often than did adolescents in always-married families. Although there was some evidence of family context differences in the connections between patterns of advice and life plans, overall, adolescents in both family contexts who received more advice from a parent and, in some cases, a sibling compared to other adolescents were the most positive about their future life plans.
