This paper compares key aspects of governance structures for Indigenous populations in the United States and Australia. The paper focuses on policy coordination and administration, in particular the nodes of decision-making in the two countries in relation to government contracting and accountability. The U.S. approach to funding Indigenous organizations stems from the 1975 Indian Self-Determination and Education Act and its subsequent expansions. Through the development of contracting into permanent compacting via block grants, this approach builds established nodes of Indigenous government and facilitates whole-of-government coherence at the level of the American Indian tribe. The U.S. approach seems correlated with better performance and may lighten bureaucratic loads over the long term. The Australian model, on the other hand, seeks to create whole-of-government coherence through top-down financial accountability in a way that hampers the development of Indigenous political capacity. The paper traces the development of these practices through time and illustrates how they contribute to the fragmentation rather than growth of Indigenous political capacities. It suggests ways the Australian model could be improved even in the absence of fundamental reform by drawing on the contracting-to-compacting framework of longstanding U.S. practices.  相似文献

In recent years, a number of middle-income countries and influential multilateral institutions have instigated actions that frame food system governance around social protection and rights. These state-centered mobilizations raise fundamental questions about how to portray the global politics of food. Since the late 1980s, analysts have largely concurred that US hegemony in the global politics of food has given way to diverse and volatile neo-liberalist and corporate-led food system governance. However, what should we make of a situation where state and supra-state actors are flexing their powers to reshape food systems in line with rights-based models? Should this be understood as reflexes which aim to preserve national order, at a time of intensified food and nutrition insecurities? Or, does it lay the foundations of a re-governed system which curbs and molds a corporate-led politics of food within frameworks of justice? This contribution responds to these questions by tracing the evolution of social protection and rights-based approaches to the politics of food at the multilateral level and in two influential jurisdictions (India and South Africa). We argue that these initiatives underline a robust and continuing role of state power in global food politics, albeit in a novel fashion compared to previous entanglements.  相似文献

School-based extracurricular activity involvement has been associated with lower levels of substance use among adolescents from various populations; however, these associations have only been slightly examined among American Indian (AI) adolescents. Building from various theoretical perspectives, it was hypothesized that AI adolescents’ perceived access to and the intensity (i.e., frequency) of participation in extracurricular activities would be associated with lower substance use and less engagement in risky substance use behaviors (i.e., being drunk or high at school, riding/driving with an intoxicated driver, and selling drugs). The moderating influences of sex, age, reservation residence, and metropolitan status also were examined. Data from the 2010 Arizona Youth Survey were analyzed for 5,701 8th, 10th, and 12th grade AI adolescents (49.1 % female). The expected protective effects of extracurricular participation were demonstrated, such that high levels of perceived availability and intensity of participation consistently predicted low levels of all outcomes. Some of these associations were moderated by one or more demographic factors, with unique patterns emerging for each behavior. Ultimately, the findings suggest that AI adolescents benefit from the availability of extracurricular activities and intensity of participation in them, but the degree of the effect is contingent upon other individual and contextual characteristics.  相似文献

We examine the relationship between the valence qualities of candidates and the ideological positions they take in U.S. House elections based on a study of the 2006 midterm elections. Our design enables us to distinguish between campaign and character dimensions of candidate valence and to place candidates and districts on the same ideological scale. Incumbents with a personal‐character advantage are closer ideologically to their district preferences, while disadvantaged challengers take more extreme policy positions. Contrary to conventional wisdom, challengers can reap electoral rewards by taking more extreme positions relative to their districts. We explore a possible mechanism for this extremism effect by demonstrating that challengers closer to the extreme received greater financial contributions, which enhanced their chances of victory. Our results bear on theories of representation that include policy and valence, although the interactions between these two dimensions may be complex and counterintuitive.  相似文献

Gaps in educational outcomes between racial/ethnic and socioeconomic groups persist in the United States, and parental involvement is often cited as an important avenue for improving outcomes among racially/ethnically diverse adolescents. This study utilized data from the Education Longitudinal Study 2002–2013 (56% female, N?=?4429), which followed 10th-graders through high school and ten years post-high school, to examine the links between parental involvement strategies and academic outcomes (grade point average and educational attainment). Participants included white, African American, and Hispanic/Latino adolescents from low-SES families. This study used recursive partitioning, a novel analytic strategy used for exploring higher-order interactions and non-linear associations among factors (e.g., parental educational involvement strategies) to predict an outcome (e.g., grade point average or educational attainment) through step-wise partitioning. The results showed that the combination of greater academic socialization and school-based involvement was beneficial for all adolescents’ grade point average, whereas the combination of home-based involvement with academic socialization and school-based involvement yielded mixed results. Greater academic socialization and home-based involvement appeared beneficial for educational attainment among African American and Hispanic/Latino adolescents, but not white adolescents. More home-based involvement and less academic socialization were associated with less educational attainment for white adolescents. Overall, the findings showed different combinations of parental educational involvement strategies were beneficial for adolescents across racial/ethnic groups, which may have implications for practice and policy.  相似文献

Research on achievement gaps by race/ethnicity and poverty status typically focuses on each gap separately, and recent syntheses suggest the poverty gap is growing while racial/ethnic gaps are narrowing. In this study, we used time-varying effect modeling to examine the interaction of race/ethnicity and poverty gaps in math and reading achievement from 1986–2005 for poor and non-poor White, Black, and Hispanic students in three age groups (5–6, 9–10, and 13–14). We found that across this twenty-year period, the gaps between poor White students and their poor Black and Hispanic peers grew, while the gap between non-poor Whites and Hispanics narrowed. We conclude that understanding the nature of achievement gaps requires simultaneous examination of race/ethnicity and income.  相似文献
