Within the broader literature concerned with potential bias in student measures of instructor effectiveness, two broad types of bias have been shown to operate in a course: internal and external. Missing is an assessment of the relative influence of each bias type in the classroom. Do internal or external types of bias matter more or less to student measures of instructor effectiveness? This question is of interest to those who recognize that many forms of bias operate in the classroom simultaneously and to great effect on course evaluations. Through the combination of quasi-experimental and survey methods, we attempt to do something not done before — simultaneously measure and compare the effects of one internal and one external type of bias to which we refer, following convention in the literature, as an internal factor and an external factor. Our findings indicate that, while both factors studied are important, perception of instructor partisanship (internal factor) is more influential on student course evaluations than our external factor (experimental treatment — literally a chocolate treat). The upshot is that American government instructors should be especially careful stating partisan positions in class. 相似文献

The dynamics of customary land rights and displacement among east African pastoralists have been the subject of extensive scholarly inquiry. Displacement to make way for other land uses, government-led privatization schemes, endogenous subdivision to defend land against outsiders, and progressive enclosure of private land in the context of the recent ‘land rush’ are some of the documented trajectories of land tenure change. Less explored is how exogenous authority systems gain traction within common property regimes to re-shape the contours of property. Laikipia, Kenya presents an ideal context for this research given the uniquely ambitious effort to conserve globally significant wildlife on private land. We focus on a group ranch owned collectively by Maa-speaking pastoralists for whom formal title was secured with the support of outside actors vested in conservation, and coupled with efforts to provide financial incentives for conservation. Findings suggest the new governance structure established in the context of land titling has become a pathway through which outside authority gains traction – with consequences for property, sovereignty and the traction of green agendas. Findings deepen understanding of how shifting authority shapes processes of alienation and legitimation, and contribute to ongoing debates about land grabs, tenure formalization and neoliberal approaches to conservation. 相似文献

A simulation-based counterfactual is one way to solve the observational equivalence challenge that seemingly “partisan” majority-party roll rates can be observed in the absence of any actual party influence. We simulate no-partisan-agenda-control counterfactual roll rates and apply them across sessions of the US House of Representatives and 86 state legislative chambers to evaluate the extent to which observed roll rates provide evidence for party influence on the legislative agenda. After assessing and controlling for the baseline risk of majority-party rolls, there is significant evidence of party influence on roll rates in some state legislatures, particularly those with rules that grant parties more agenda power, and in the post-Reed’s-rules House of Representatives. Institutional rules interact with the (simulated) risk of a majority roll to shape observed roll rates across chambers and across time. 相似文献

Regulation increasingly mandates collaborative approaches to increase stakeholder input and streamline approval processes. However, understanding how to maintain stakeholder involvement over the course of a long collaborative process is vital to optimize effectiveness. This paper observes more than 700 stakeholders involved in developing and implementing a dam operating license over 16 years. We use text mining and Bayesian hierarchical modeling to observe meeting attendance and recorded actions in meeting minutes. We find that involvement decreased after the initial planning phase, but steadily increased through license development and implementation. After the regulatory mandate to consult with external stakeholders dissolved, overall attendance declined while attendance stability increased, meaning that the non‐mandatory stage involved a smaller cadre of dedicated actors. This indicates that high‐performing mandated stakeholder involvement processes rely on a constrained group of conveners to sustain interaction and have less turnover than what might be expected given existing evidence from grassroots involvement; assumptions about group dynamics based on involvement in grassroots processes may lead to improper predictions about who will participate, and how, in processes where stakeholder involvement is mandated. 相似文献

A prominent position in the global justice literature holds that claims of distributive justice are only 'activated' by the densely coercive institutional apparatus of states. I dispute this view in three ways. First, I argue that coercion is either justified by its results and rationale or it cannot be justified at all; as a result, coercive institutions do not demand an independent justification via distributive justice. Second, I contend that because the shape of coercive institutions is the result of political choices that have distributive implications, one cannot make normative judgements without asking why coercive institutions have the shape that they do. Third, even accepting (for the sake of argument) the claim that coercive institutions must be justified by a special focus on distributive justice among those subject to them, I argue that the resulting position does not justify restricting distributive justice to state borders. If (any of) these arguments are correct, it is a mistake to think that a concern with the coercive nature of political institutions legitimates restricting claims of distributive justice to compatriots. 相似文献

Cocaine in Wayne County Medical Examiner's cases 总被引:1,自引:0,他引:1
We determined the incidence of detection of cocaine or its metabolites in Wayne County (Michigan) Medical Examiner's cases from 1984 to 1987. Over this four-year period there was a significant (P less than 0.01) increase each year in evidence of recent cocaine use in this population, reaching 38.3% of all tested cases in 1987. Much of this increase was accounted for by homicide victims, especially those in their third or fourth decade of life, of whom 58.6 and 56.3%, respectively, tested positive in 1987. There was a large increase in recent cocaine use in teenage homicide victims in 1987, having previously changed little from 1984 to 1986. In victims of drug abuse, recent cocaine use also increased significantly (p less than 0.01) each year, reaching 47.6% in 1987, generally in combination with heroin. Although deaths attributed solely to cocaine were not as common, they also increased significantly each year from 4 in 1984 to 25 in 1987. Compared with the general population, those who use cocaine in Wayne County are more likely than those who do not to die prematurely, often as a result of violence. 相似文献

We develop an approach to conducting large-scale randomized public policy experiments intended to be more robust to the political interventions that have ruined some or all parts of many similar previous efforts. Our proposed design is insulated from selection bias in some circumstances even if we lose observations; our inferences can still be unbiased even if politics disrupts any two of the three steps in our analytical procedures; and other empirical checks are available to validate the overall design. We illustrate with a design and empirical validation of an evaluation of the Mexican Seguro Popular de Salud (Universal Health Insurance)program we are conducting. Seguro Popular, which is intended to grow to provide medical care, drugs, preventative services, and financial health protection to the 50 million Mexicans without health insurance, is one of the largest health reforms of any country in the last two decades. The evaluation is also large scale, constituting one of the largest policy experiments to date and what may be the largest randomized health policy experiment ever. 相似文献
