Adolescent girls aged 12 through 16 years, identified as either educable mentally retarded, behaviorally disordered, learning disabled, or nonhandicapped, were rated by their teachers on the Behavior Problem Checklist. Analysis of these ratings revealed significant differences for pupil category, Behavior Problem Checklist dimension, and category-by-dimension interaction. Behaviorally disordered students showed a greater degree of maladjustment than the retarded and nonhandicapped students on all four checklist dimensions, and exceeded the learning disabled on three dimensions (not Personality Problem). Implications for further research and special educational practices based on the present findings are discussed.Received Ed.D. from University of Virginia.

With increasing frequency, relatively small, fragmentary evidence thought to be osseous or dental tissue of human origin is submitted to the forensic laboratory for DNA analysis with the request for positive identification. Prior to performing DNA analysis, however, it is prudent to first perform a presumptive test or "screen" to determine whether the questioned material may be eliminated from further consideration. When material is shown not to be consistent with bone/teeth, DNA testing is not performed. When such determinations cannot be made from gross morphological features, elemental analysis can be indicative. This presumptive test is made possible by applying scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) in conjunction with an X-ray spectral database recently developed by the FBI laboratory. This database includes spectra for many different materials including known examples of bone and tooth from many different contexts and representing the full range of taphonomic conditions. Results of SEM/EDS analysis of evidence can be compared to these standards to determine if they are consistent with bone and/or tooth and, if not, then what the material might represent. Analysis suggests that although the proportions and amounts of calcium and phosphorus are particularly important in differentiating bone and tooth from other materials, other minor differences in spectral profile can also provide significant discrimination. Analysis enables bone and tooth to be successfully distinguished from other materials in most cases. Exceptions appear to be ivory, mineral apatite, and perhaps some types of corals. 相似文献

Mitochondrial DNA (mtDNA) analysis of forensic samples typically is performed when the quantity and quality of DNA are insufficient for nuclear DNA analysis or when maternal relatives may be the only reference source. Many of the steps required in the analytical process are both lengthy and labor intensive. Therefore, improvements in the process that reduce labor without compromising the quality of the data are desirable. The current procedure requires purification of the amplicons by centrifugal filtration after PCR and prior to cycle sequencing. Because this method requires several manipulations to perform, alternate cleanup procedures were investigated. These include the use of 1) Qiagen QlAquick PCR Purification columns, 2) Concert Rapid PCR Purification columns, and 3) ExoSAP-IT reagent. When the yield of purified amplicons, quality of the sequence profile, and ease of assay were evaluated, the use of ExoSAP-IT reagent for post-amplification purification was chosen to replace the filtration method. 相似文献

Public management scholars often claim that agency competition provides an effective institutional check on monopoly authority, and hence, leads to improvement of administrative performance in public sector agencies. This logic was central for creating the Congressional Budget Office (CBO) in 1975 to challenge the policy information provided by the Office of Management and Budget (OMB). We challenge this conventional wisdom by demonstrating that CBO has failed to enhance the quality of U.S. fiscal policy analysis on its own terms; nor has it spurred improvements in OMB's performance. Our empirical results indicate that the quality of OMB's fiscal projections has often deteriorated since the establishment of CBO as a rival bureau. We also show that both public and private information is being shared by these agencies to produce a similar caliber of task outputs. The broader implications of our study indicate that although politicians face incentives to employ agency competition in governmental settings, this type of bureaucratic strategy does not necessarily enhance the quality of administrative performance. © 2006 by the Association for Public Policy Analysis and Management 相似文献

20世纪以来,众多文化研究学者,从卢卡奇(Georg Lukacs)、葛兰西(Antonio Gramsci)、布罗齐(Ernst Bloch)、本杰明(Walter Benjamin)、阿多诺(Theodor W Adorno)、杰姆逊(Fredric Jameson)、伊格尔顿(Terry Eagleton)等人,均专注于马克思主义理论研究,分析文化形式与文化发展、社会历史的关系,了解文化形式对大众和社会生活的作用与影响。因此,要把握文化研究的发展路向,在现时期理解文化研究的各种类型和表现形式,必须了解文化马克思主义传统。一、文化马克思主义的兴起1.马克思与恩格斯马克思和恩格斯虽在研究中提及文化现象,但具体… 相似文献

As the debates over cloning and stem cell research indicate, issues raised by biotechnology combine research into the genetic sciences, perspectives and contexts articulated by the social sciences, and the ethical and anthropological concerns of philosophy. Consequently, we argue that intervening in the debates over biotechnology require supradisciplinary critical philosophy and social theory to illuminate the problems and their stakes. More specifically, we will demonstrate problems with the cloning of animals that for now render the cloning of humans unacceptable. In addition, we take on arguments for and against stem cell research and contend that it contains positive potential for medical advances that should not be blocked by problematic conservative positions. Nonetheless, we believe that the entire realm of biotechnology is fraught with dangers and problems that require careful study and democratic debate of key ethical and political issues. 相似文献

Critics of the civil jury have proposed several procedural reforms to address the concern that damage awards are capricious and unpredictable. One such reform is the bifurcation or separation of various phases of a trial that involves multiple claims for damages. The purpose of this study was to assess the effects of bifurcating the compensatory and punitive damages phases of a civil tort trial. We manipulated the wealth of the defendant and the reprehensibility of the defendant's conduct (both sets of evidence theoretically related to punitive but not to compensatory damages) across three cases in a jury analog study. We wondered whether jurors would misuse the punitive damages evidence in fixing compensatory damages and whether bifurcation would effectively undo this practice. Our findings indicated that mock jurors did not improperly consider punitive damages evidence in their decisions about compensation. Moreover, bifurcation had the unexpected effect of augmenting punitive damage awards. These findings raise questions about the merits of bifurcation in cases that involve multiple claims for damages. 相似文献
