List and endorsement experiments are becoming increasingly popular among social scientists as indirect survey techniques for sensitive questions. When studying issues such as racial prejudice and support for militant groups, these survey methodologies may improve the validity of measurements by reducing nonresponse and social desirability biases. We develop a statistical test and multivariate regression models for comparing and combining the results from list and endorsement experiments. We demonstrate that when carefully designed and analyzed, the two survey experiments can produce substantively similar empirical findings. Such agreement is shown to be possible even when these experiments are applied to one of the most challenging research environments: contemporary Afghanistan. We find that both experiments uncover similar patterns of support for the International Security Assistance Force (ISAF) among Pashtun respondents. Our findings suggest that multiple measurement strategies can enhance the credibility of empirical conclusions. Open‐source software is available for implementing the proposed methods. 相似文献

Despite claims that school districts need flexibility in teacher assignment to allocate teachers more equitably across schools and improve district performance, the power to involuntarily transfer teachers across schools remains hotly contested. Little research has examined involuntary teacher transfer policies or their effects on schools, teachers, or students. This article uses administrative data from Miami‐Dade County Public Schools to investigate the implementation and effects of the district's involuntary transfer policy, including which schools transferred and received teachers, which teachers were transferred, what kinds of teachers replaced them in their former schools, and how their performance—as measured by their work absences and value‐added in math and reading—compared before and after the transfer. We find that, under the policy, principals in the lowest performing schools identified relatively low‐performing teachers for transfer who, based on observable characteristics, would have been unlikely to leave on their own. Consistent with an equity improvement, we find that involuntarily transferred teachers were systematically moved to higher performing schools and generally were outperformed by the teachers who replaced them. Efficiency impacts are mixed; although transferred teachers had nearly two fewer absences per year in their new positions, transferred teachers continued to have low value‐added in their new schools. 相似文献

Abstract: There remains significant uncertainty in illicit marijuana cultivation. We analyzed the δ13C and δ15N of 508 domestic samples from known U.S.A. counties, 31 seized from a single location, 5 samples grown in Mexico and Colombia, and 10 northwest border seizures. For a subset, inflorescences and leaves were analyzed separately. These data revealed a strong correspondence, with inflorescences having slightly higher δ13C and δ15N values than leaves. A framework for interpreting these results is introduced and evaluated. Samples identified as outdoor‐grown by δ13C were generally recorded as such by the Drug Enforcement Administration (DEA). DEA‐classified indoor‐grown samples had the most negative δ13C values, consistent with indoor cultivation, although many were also in the outdoor‐grown domain. δ15N indicated a wide range of fertilizers across the dataset. Samples seized at the single location suggested multiple sources. Northwest border δ13C values suggested indoor growth, whereas for the Mexican and Colombian samples they indicated outdoor growth. 相似文献

Calculation of a blood alcohol concentration (BAC) at the time of an offence by forward or back-extrapolation, using population average values for ethanol pharmacokinetic parameters or a single estimate of individual specific parameters, ignores the possibility of inter- and intra-subject variability. In order to estimate inter- and intra-subject variability in the elimination rate and absorption rate, BAC was measured over time in 12 male volunteers on 4 occasions. Subjects received 0.44 g kg(-1) body weight of ethanol on the first study day, and 0.70 g kg(-1) body weight on subsequent study days 1, 11 and 12 weeks later, to enable comparisons in variability over short and long time periods and when the same or different doses were administered. Evidence of both inter- and intra-subject variability was found, with inter-subject variability substantially smaller than intra-subject variability when the dose varied. Forensically important differences in pharmacokinetic parameters were observed within individuals between occasions. These findings could have an important impact on medico-legal issues related to ethanol pharmacokinetics. 相似文献

This paper examines the United States policy toward people with AIDS (PWAs) using a theory of the social construction of target populations (Schneider and Ingram, 1993). A policy narrative is developed which focuses on the ways PWAs have been categorized throughout the epidemic and how the characterization of these constructed target populations has influenced the design of policies aimed at these groups. The Ryan White Act of 1990 and the debate surrounding its passage is examined and found to be consistent with the expectations of the theory. Propositions which extend the framework are offered as a guide for future research. 相似文献

To date, there is no literature specifically addressing the relationship between spousal battering and emotional intelligence, a concept that captures the success, or lack thereof, of a person's functioning in their immediate environment. Forty-four men convicted of spousal assault and 76 undergraduate students completed the Emotional Quotient Inventory (EQ-i; R. Bar-On, BarOn Emotional Quotient Inventory: User's Manual, Multi-Health Systems, Inc., Toronto, 1997), the Propensity for Abusiveness Scale (PAS; D. G. Dutton, J. Fam. Violence 10(2): 203–221, 1995), and the Balanced Inventory of Desirable Responding (D. Paulhus, J. Pers. Soc. Psychol. 46: 598–609, 1984; Assessing Self-Deception and Impression Management in Self-Reports: The Balanced Inventory of Desirable Responding, Unpublished manual, University of British Columbia, Vancouver, Canada, 1988; In Measures of Personality and Social Psychological Attitudes, Academic Press, San Diego, CA, pp. 17–59, 1991). Results of this exploratory study indicate that batterers score significantly lower than the general population on all components of EQ-i. Additionally EQ-i total and subscale scores for both samples correlate negatively and significantly with scores on PAS, suggesting that deficits in various components of emotional intelligence are related to an increase in the propensity to be abusive. Implications for batterer treatment are discussed. 相似文献

This study examines the failure of a small but significant element of U.S. chemical regulatory policy: the Endocrine Disruptor
Screening Program (EDSP). A range of conditions are implicated in the failure of this program, but one condition, the scientific
testing and regulation paradigm (STRP), seems particularly important and ties the failure of EDSP to the failure of other
U.S. chemical regulatory programs. This paradigm is a group of assumptions that have driven pesticide (and other chemical)
regulatory policy since World War II. This study investigates the relationship between STRP and the failure of EDSP, the potential
efficacy of alternatives to this program, and one alternative that broke from this paradigm. Ultimately, this study suggests
that we must revise the role of science in regulation in order to find effective alternatives to modern chemical regulatory
policy. 相似文献

The Federal Sentencing Guidelines were developed to provide uniform and standardized punishments for eliminating sentence disparities based on legally irrelevant factors. While research at the individual level showed that extralegal factors continued to affect sentence outcomes, no such research determined if these factors influenced sentencing of organizational offenders. This article extends the unit of analysis beyond the individual and toward organizational offenders to determine if total fine amounts are affected by extralegal organizational characteristics. Relying on post-1991 organizational defendant's data, the findings indicated both legal and extralegal factors significantly affected fine outcomes for organizational offenders. As expected, several legal factors significantly affected fine outcomes. At least two extralegal variables, economically solvent and closely held organizations, however, exerted significant effects in predicting the total fine amount imposed. Similar to research at the individual level, this study indicated that extralegal or legally irrelevant factors had some level of impact upon sentencing under the guidelines. 相似文献
