Throughout his career as a literary critic, Alfred Kazin wrote often and with sympathy and insight about Theodore Dreiser, one of the most powerful, panoramic, and compassionate novelists in American literary history. Kazin was an intense reader and writer, committed in his books, essays, and reviews to connecting with and describing the personality of each author he examined. His interpretive work on Dreiser illuminates what it means to be a literary critic and teacher. When we read Kazin in the midst of twenty-first century theory, ideology, and professionalism, we realize all the more clearly the goal in his literary criticism that he aimed for, achieved, and represented—and that now is missing from literary education and experience. 相似文献

While the fertility effects of improving teenagers’ access to contraception are theoretically ambiguous, most empirical work has shown that access decreases teen fertility. In this paper, we consider the fertility effects of access to condoms—a method of contraception not considered in prior work. We exploit variation across counties and across time in teenagers’ exposure to condom distribution programs in schools. We find that access to condoms in schools increases teen fertility by about 12 percent. The results suggest that the effects of condom access varied significantly across different programs; the positive fertility estimates are driven by communities where condoms are provided without mandated counseling. Programs that mandated counseling have zero or negative fertility effects, but estimates on these counties are less robust across specifications. 相似文献

Although interest in research utilization in the policy process has grown, how advocates strategically deploy different types of evidence to influence lawmakers remains not well understood. In this paper, we draw on the Advocacy Coalition Framework and the Narrative Policy Framework to show how various types of evidence—from empirical findings to personal anecdotes—were utilized by advocates during the 2 years leading to the passage of California’s historic 2010 law to extend foster care. The result was a generous and flexible entitlement policy passed with bipartisan support in the context of a recession, a state budget deficit, and an ambivalent governor. We find that leaders of a diverse advocacy coalition strategically showcased different types of evidence at specific moments in the legislative process. Each evidence type can be tied to a specific narrative element and strategy. Advocates first used research evidence to convince lawmakers of the policy’s effectiveness, then used professional expertise and benefit-cost analysis to convince them it would come at an acceptable cost, and finally used personal narratives to motivate them to act. We conclude that though benefit-cost analyses play an integral role in policymaking during a time of austerity, advocacy coalitions may still benefit from personal stories that lend emotional potency and urgency. 相似文献

It is time to imagine a new policy sciences. The policymaking world has moved on since its first design. So too has our understanding of it. The original policy sciences were contextualized, problem-oriented, multi-method, and focused on using scientific research towards the realization of greater human dignity. We introduce a new policy sciences that builds on such aims. We describe the need for realistic depictions of ‘rational’ and ‘irrational’ choice, multiple theories to portray the multifaceted nature of complex contexts, and the combination of applied and basic research. To set this new agenda, we build on two foundational strategies: identifying advances in the psychology of decision-making and describing how policy theories depict policymaking psychology in complex contexts. 相似文献

This paper tests whether the political connections of banks were important in explaining participation in the Federal Reserve’s emergency lending programs during the recent financial crisis. Our multivariate tests show that banks that were politically connected—either through lobbying efforts or employment of politically connected individuals—were substantially more likely to participate in the Federal Reserve’s emergency loan programs. In economic terms, participation in these programs was 28–36% more likely for banks that were politically connected than for banks that were not politically connected. In our final set of tests, we attempt to identify a proper explanation for this peculiar relationship. While a broad literature speaks of the moral hazard associated with receiving bailouts, we test whether another type of moral hazard exists in the period preceding the bailout. In particular, we argue that, to the extent that political connections act as synthetic insurance, banks may have engaged in more risky behavior that lead them to the Fed’s emergency lending facilities. Tests seem to confirm this explanation. 相似文献

We introduce experimental research design to the study of policy diffusion in order to better understand how political ideology affects policymakers’ willingness to learn from one another's experiences. Our two experiments–embedded in national surveys of U.S. municipal officials–expose local policymakers to vignettes describing the zoning and home foreclosure policies of other cities, offering opportunities to learn more. We find that: (1) policymakers who are ideologically predisposed against the described policy are relatively unwilling to learn from others, but (2) such ideological biases can be overcome with an emphasis on the policy's success or on its adoption by co‐partisans in other communities. We also find a similar partisan‐based bias among traditional ideological supporters, who are less willing to learn from those in the opposing party. The experimental approach offered here provides numerous new opportunities for scholars of policy diffusion. 相似文献
