In its 1993 report, the Winter Commission gave direction to the federal government in the area of health policy and Medicaid: lead, follow, or get out of the way. This article examines how the federal government responded to that advice, specifically asking what has happened in the allocation of responsibility in health policies between 1993 and 2006. In short, unlike the suggestion that there be a better‐defined direction in federal–state policy assignments in health, the ensuing years have resulted in more of the same. The authors examine what has happened, particularly focusing on vertical diffusion—where the states have acted first—and on the role of policy learning in federal decision making. They find little recognition of policy learning in recent federal health laws—even in areas in which state experience was extensive. The federal government is leading in some health policies—but it is leading without learning. 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

The transition from adolescence to adulthood is a critical time for status attainment, with income, education, work experience, and independence from parents accruing at varying speeds and intensities. This study takes an intergenerational life-course perspective that incorporates parents’ and one’s own social status to examine the status attainment process from adolescence into adulthood in the domains of economic capital (e.g., income) and human capital (e.g., education, occupation). Survey data from three waves of the National Longitudinal Study of Adolescent Health (analytic n = 8,977) are analyzed using latent class analysis to capture the ebb and flow of social status advantages and disadvantages from adolescence (Wave 1) through young adulthood (Wave 3) into adulthood (Wave 4). The analytic sample is composed of 50.3 % females and 70.2 % Whites, 15.3 % Blacks, 11.0 % Hispanics, and 3.5 % Asians ages 12–18 at Wave 1 and 25–31 at Wave 4. Four latent classes are found for economic capital and five for human capital. The importance of parents’ social status is demonstrated by the presence of large groups with persistently low and persistently high social status over time in both domains. The capacity of individuals to determine their own status, however, is shown by equally large groups with upward and downward mobility in both domains. These findings demonstrate the dynamic nature of social status during this critical developmental period. 相似文献

‘Flex crops’ such as corn, oil palm and soy are understood to have multiple, interchangeable uses; they have material flexibility. We propose that discursive flexibility – the ability to strategically switch between discourses to promote an objective – equally shapes the political economy of flex crops, and thereby patterns of agrarian and environmental change. Comparing oil palm and Jatropha curcas, we find that actors who cast oil palm as a multi-scale solution to food and energy insecurity, climate change and (rural) poverty successfully reinforce its high material flexibility. Jatropha's proponents compensate for low material flexibility by positioning the crop as a ‘sustainable’ energy source that achieves both global and local goals. While this paper focuses on discourses that reinforce the oil palm and jatropha projects, understanding the power of discursive maneuvering can also inform efforts to contest them. 相似文献

Engaging the lively debates about the next expression of neoliberalism, this study suggests that it is evolving into philanthrocapitalism. After a brief discussion of the trajectories from neoliberalism, the article addresses the core ideology of philanthrocapitalism. The central thesis explores how philanthrocapitalism is moving beyond the requirement of ‘business practices’ for recipients of donor funds, into enforcing ‘business rule’ on to the public domain. Although philanthrocapitalism is most debated in the fields of health care and education, this article uses empirical analysis of international agricultural policies trying to enlist Southern Africa policies. It explores how philanthrocapitalist rule is reducing transparency, participation and deliberation within the public domain, well beyond requesting efficient business practices for greater food security. It concludes with how smallholder farmers are actively organising to resist business rule over their genetic resources and farming practices. 相似文献

Democratic governance depends not only on the building of democratic institutions but also on citizens' knowledge about how these institutions should function in their everyday lives. I argue that US-hosted educational exchange programs are one mechanism whereby citizens of nondemocratic states might experience life firsthand in a democratic country. Their experiences may impact the political institutions and influence political behavior in their home countries. In order for this process to take place, I argue that at least three contextual conditions are important: (i) the depth and extent of social interactions that occur while abroad, (ii) the sharing of a sense of community or common identity between participants and their hosts, and (iii) the attainment of a politically influential position by the exchange participant when they return home. In this article, I test these hypotheses and find support for what advocates of soft power often contend: US-hosted exchange programs can play an important role in the diffusion of liberal values and practices across the borders of authoritarian states. 相似文献

‘Intelligence’ connotes the collection of information in furtherance of policy and strategic security objectives. Intelligence practitioners tend to look primarily to the histories of battlefield reconnaissance and court intrigue for their profession's discursive precedents. For the Western state, the mastery of territory has also been an important security objective since the Age of Exploration. Specifically, in the American case, territorial expansion and the subduing of new territory long lay at the heart of America's viability as a state. Thus, the intelligence field ought also to recognize geographical exploration as deeply implicated in Western national security discourse and as sharing an epistemological similarity with intelligence gathering. Both intelligence gathering and geographical exploration rely upon ‘Humint’, that is, informants penetrating distant and hidden places and reporting on the features found therein. America's early Republic period offers key examples of this fundamental similarity. 相似文献

Cathinone derivatives (bath salts) have emerged as the latest drugs of abuse. 3,4‐methylenedioxypyrovalerone (MDPV) is the primary active ingredient in bath salts used in this country. This article presents the second reported cause of death by MDPV intoxication alone. In April 2011, a delusional man was emergently brought to a hospital, where he self‐reported bath salt usage. He became agitated, developed ventricular tachycardia, hyperthermia, and died. Comprehensive alcohol and drug testing was performed. Using the alkaline drug screen, heart blood contained 0.7 mg/L MDPV and peripheral blood contained 1.0 mg/L MDPV. His bizarre behavior with life‐threatening hyperthermia was consistent with an MDPV‐induced excited delirium state. MDPV is not yet found by routine immunoassay toxicology screens. Testing for MDPV should be considered in cases with a history of polysubstance abuse with stimulant type drugs, report of acute onset of psychogenic symptoms, excited delirium syndrome, or presentation in a hyperthermic state. 相似文献
