A decade of economic stagnation has produced a plethora of calls for government action to stimulate economic growth in employment. Arguing that activists federal industry policy is likely not to emerge in the United States, Rasmussen and Ledebur examine the potential role of states in a "federalist industry policy." States presently administer effective programs of financial assistance to business enterprises. These efforts are "rationally parochial" in that their purpose is served equally well by cresting a new job or pirating from other jurisdictions. This paper considers how state programs can be reoriented to serve national growth and development objectives as well as those of specific jurisdictions. It concludes that a subnational industry policy offers a unique opportunity to reallocate existing state resources to achieve a much higher social return.  相似文献

Students of state politics have long been interested in the partisanship and the degree of interparty competition in the American states. This has led to numerous attempts to quantify state-level partisanship and competition, the most significant by Ranney (1965). Interestingly, however, scholars have never specified clearly the relationship between these two concepts as measured by the Ranney index. This research attempts to do just that and reveals that the two are different measures which are related systematically. More important, understanding changes in a state's partisanship is determined to be crucial to understanding changes in its level of two-party competition. As such, in order to explain changes in partisanship and competition across the American states from the 1950s to the 1970s, we focus on accounting for changes in partisanship. To this end, changes in aggregate demographic variables account very well for states' movement along the Ranney index over the last 3 decades.The names of the authors appear in alphabetical order and imply that this paper is in every way a collaborative enterprise.  相似文献

As organ transplantation procedures become accepted as standard medical practice, it is anticipated that the frequency of liability claims against transplant care providers will increase. This article examines current statutory and common law analyses of malpractice issues in transplantation, with particular attention given to issues of informed consent as they arise both for the organ donor and donee.  相似文献

EDA for HLM: Visualization when Probabilistic Inference Fails   总被引:1,自引:1,他引:0  
e-mail: jwbowers{at}umich.edu (corresponding author) e-mail: kwdrake{at}umich.edu Nearly all hierarchical linear models presented to politicalscience audiences are estimated using maximum likelihood undera repeated sampling interpretation of the results of hypothesistests. Maximum likelihood estimators have excellent asymptoticproperties but less than ideal small sample properties. Multilevelmodels common in political science have relatively large samplesof units like individuals nested within relatively small samplesof units like countries. Often these level-2 samples will beso small as to make inference about level-2 effects uninterpretablein the likelihood framework from which they were estimated.When analysts do not have enough data to make a compelling argumentfor repeated sampling based probabilistic inference, we showhow visualization can be a useful way of allowing scientificprogress to continue despite lack of fit between research designand asymptotic properties of maximum likelihood estimators.  相似文献

This paper focuses on the psychology of social change and social justice. Specifically, we focus on subordinates’ reactions to new and old supervisors, and we argue that in evaluating these different types of supervisors, subordinates may rely on prior fair or unfair experiences as temporal frames of reference. We further propose that a result of these frames of reference may be that previous fairness experiences have a bigger impact on subordinates’ reactions to subsequent neutral communications when an old rather than when a new supervisor is the source of that communication. Findings of two empirical studies indeed show that subordinates who had had fair experiences with a particular supervisor reacted more positively toward subsequent neutral messages when the communication was coming from the old supervisor rather than from the new supervisor. Subordinates who had had unfair experiences, however, reacted more negatively toward the communication when the source was the old rather than the new supervisor. Some evidence was also found for contrast effects such that people who react to a new supervisor may react more positively with the neutral demand from this authority figure when they have earlier experienced unfair as opposed to fair treatment by a different supervisory agent. These findings were obtained on subordinates’ satisfaction with the supervisors’ communication and their acceptance of the supervisor. Finally, we discuss the implications for the psychology of social change and social justice.  相似文献
