Communicators try to shape public opinion to their advantage by invoking social values. We examine a vivid example of this value framing in the debate over teaching evolution in the public schools. Supporters of intelligent design (ID) theory have pressed for greater acceptance in public schools by framing the issue as a question of fairness. A survey experiment revealed overwhelming agreement that including ID in science class is fairer than excluding it. This belief had a greater impact on tolerance for ID when the issue was framed with respect to fairness. A second study showed similar effects from a pro-ID documentary film. A final study showed that training in scientific reasoning counteracts the impact of the fairness value, thereby decreasing tolerance for ID. Combined, these studies show how political debate can be understood as a contest over which values deserve greatest consideration or emphasis. 相似文献

Between February 1999 and May 2005, 116 DNA extractions were completed on skeletal remains from routine casework. Overall, at least a partial mitochondrial DNA (mtDNA) profile was obtained on 83.6% of samples. Skeletal remains fell into two general categories: (1) samples for body identifications submitted by law enforcement and (2) samples submitted to answer historical or family identity questions. Body identification cases were more likely to yield full mtDNA profiles, whereas historical cases were more likely to result in partial profiles. Overall, the ability to obtain a full or partial profile primarily reflects the difference in the average age and condition of the samples in these two categories and thus, difference in the quantity and quality of the DNA. Cremated remains were uniformly unsuccessful, whereas infant/fetal remains were uniformly successful. Heteroplasmy in skeletal remains was observed at a rate similar to that in hair ( approximately 10%). For body identification cases, skeletal remains had the same mtDNA profile as the accompanying reference sample in 50% of cases. 相似文献

Unexpected revenue shortfalls that occur during budget execution create serious problems for public agencies and programs. This is especially true for agencies and programs that rely upon a single source of revenue. This article implements a revenue monitoring process that combines ideas from statistical process control and exploratory data analysis into a spreadsheet environment. The methodology builds on principles used to monitor manufacturing processes. This simple application helps public managers detect revenue surpluses and deficits early enough in the budget execution process to take corrective action. The methodology also adapts to the data problems and avoids many of the pitfalls that arise when using "real world" budget data. An example of the benefits of this methodology is offered using an example of a state agency funded by a single revenue source. 相似文献

As retailers in the North increasingly adopt codes of practice containing social and/or environmental provisions in global supply chains, there is a need for rigorous assessment of their social impact. Moving beyond the rhetoric, it is important to establish the actual impact of such codes on poorer workers, their families, and other local stakeholders. This paper sets out the key methodological and conceptual issues arising in such an assessment as identified by a three-year study on the South African wine industry. It reviews the different motivations and approaches employed by code bodies, donors, academics, and practitioners, and highlights the lack of workers' voices in the debate on corporate responsibility as well as some of the early research findings. Finally, it explains how the inherent power inequalities in global supply chains make it more difficult to adopt a truly empowering approach to assessing the impact of codes of practice. 相似文献
