Calibration is commonly used in order to specify a numerical computable general equilibrium model. As it involves the evaluation of model parameters on the basis of a single observation, there is a concern about the reliability of the results obtained from the model. A one-sector model for the Polish economy is specified and calibrated using various years as a benchmark equilibrium. Different assumptions are also made about some elasticity parameters. The model response is examined by simulating an increase in government expenditure. The results are quite robust to the choice of the base year but very sensitive to some elasticity parameters such as trade substitution elasticities.  相似文献

Multiple-item measures of self-reported offending typically provide the principal outcome measures for individual level research on the causes of crime and deviance. This article directs attention to the substantial problems presented by the task of forming composite scores for these measures, and it presents a possible solution to those problems. We consider scaling by means of the graded response model from item response theory (IRT) as a potential means of overcoming the shortcomings of traditional summative scaling and of obtaining valuable information about the strengths and weaknesses of our measures. We illustrate this strategy through a scale analysis of a fourteen-item, self-report measure of delinquency, using three years of data from the Monitoring the Future study, an annual national survey of high school seniors. The graded response model proves to be consistent with the data, and it provides results that address important substantive questions about self-report measures. The findings are informative about the strengths and weaknesses of alternative strategies for developing self-report instruments, indicating that there is little to be gained by making fine distinctions in the frequency of individual delinquent acts.  相似文献

While the plea of duress is generally accepted as a defense against criminal prosecution, the reasons why it exonerates are subject to dispute and disagreement. Duress is not easily recognizable as either an excusing or justifying condition. Additionally, duress is generally not permitted as a defense against criminal homicide, though some American jurisdictions allow the defense in felony-murder cases. In this paper, I present an argument for how and why the presence of duress can defeat a finding of criminal responsibility. This is intended to establish the philosophical foundation for the legal acceptability of the duress defense, even though I conclude that the defense does not qualify as either an excuse or a justification. I also argue that the duress defense should be allowed in cases of homicide.  相似文献

This study investigates the types of factors which can lead to government acquisition, or the “spin-in” of bio-defense technologies from small bio-technology firms. Empirical findings suggest that for small biotechnology R&D firms desiring to increase “spin-in” technology transfer, there appears to be two distinct and important influence groups—the scientific community within federal agencies, institutes, and centers, and the more managerial, policy-oriented decisions makers. We found that personal communication and networking appear to be the primary factor that leads to a successful technology transfer, however, the form and substance of personal communication and networking will differ between the two influence groups.  相似文献

We report the results of two studies designed as follow-ups to our earlier research on the comprehension of capital penalty instructions. In the first study we examine whether a California penalty instruction that was revised by the courts to improve its comprehension by jurors accomplishes this goal. In the second study we content-analyze a sample of attorney closing arguments that were given at the conclusion of actual capital penalty phases to explore whether they are likely to clarify those concepts and procedures that are so poorly comprehended in the judge's instructions. Results indicate that the revised instruction suffers from the same comprehension problems that plagued its predecessor and that attorney arguments appear unlikely to significantly reduce confusion among capital jurors.  相似文献

Leading police scholars and practitioners were asked to reflect on the most urgent issues that need to be addressed on the topic of use of force. Four themes emerged from their contributions: use of force and de-escalation training needs to improve and be evaluated; new ways of conceptualizing use of force encounters and better use of force response models need to be developed; the inequitable application of force, and how to remediate biases, needs to be more fully understood; and misconceptions about police use of force need to be identified and corrected. The highlighted topics serve as an agenda for future research. Such research should provide greater insight into when, where, and why force is used by police officers, and how it can be applied appropriately. If implemented, the practical recommendations included in the contributions should have a positive impact on police performance, public trust and confidence in the police, and citizen and officer safety.  相似文献

This article examines the state of intensive family preservation services (IFPS) research. Using studies of IFPS in five states, this article seeks to establish whether IFPS can be regarded as an evidence-based practice, an increasingly important standard for publicly funded services. While reporting rates of repeat child maltreatment, the analysis uses placement rates as the main outcome measure and compares effect sizes using Cohen's arcsine transformation for data reported as proportions. Significant differences in rates of child out-of-home placement and repeat maltreatment were found in some studies, particularly for higher risk families. The findings also underscore the difficulty of identifying which families to serve (targeting), ensuring treatment fidelity, and employing rigorous and appropriate evaluation methods. Overall, additional research is needed to move IFPS from a promising practice to an evidence-based practice.  相似文献

Scotland has laid claim to being ‘different’ from the rest of the UK with regards to disability policy. This article examines the evidence for that with regard to long‐term and social care, and discusses the possibilities opened up by the devolution of disability benefits. It asks whether Scotland will demonstrate policy divergence from the rest of the UK, and whether that is likely to be beneficial for disabled people. It argues that Scotland has the potential to create better social policies for disabled people, but faces significant challenges in doing so.  相似文献
