Behavior problems of handicapped adolescent female students

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.

The use of SEM/EDS analysis to distinguish dental and osseus tissue from other materials

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.     

An improved method for post-PCR purification for mtDNA sequence analysis

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.     

布莱尔、布朗的鹰谷议程与全球政治的不平等发展

2005年7月在苏格兰鹰谷(Gleneagles)举行的八国首脑会议上,布莱尔和布朗提出了帮助贫困国家发展的议程。通过反思“鹰谷”会议及其后续会议的成果与启示,批评布莱尔、布朗和“变贫困为历史”活动内在包含的概念框架,可以看到,“变贫穷为历史”的目标是无法实现的。在金融、贸易和环境领域等发展策略的三个主要竞技场中,世界各国于一种复杂的结构不平等模式中运作。布莱尔和布朗的鹰谷议程不得不面对不平等发展的全球政治,而且这个议程由于这些政治条件的限制被弄得歪七扭八。     

Does agency competition improve the quality of policy analysis? Evidence from OMB and CBO fiscal projections

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     

State Poverty Rates: Do the New Welfare Policies Make a Difference?

This article uses four models to identify the best predictors of state poverty levels and changes in state poverty rates since the implementation of welfare reform. The policy decisions based on the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) by the states are tested along with more traditional variables identified in the literature. Using several measures of state poverty, the analysis finds that those states with the lowest poverty rates are those with the healthiest economies, and the most generous state spending on Temporary Assistance for Needy Families (TANF). States with the highest percentage of their TANF rolls made up of black citizens tend to have the highest rates of poverty. Initial poverty rates are found to be important in that states with higher initial poverty levels are capable of generating a larger reduction in poverty than states with lower initial rates. With the exception of limited evidence on sanctions, none of the PRWORA–based policies were found to have any effect on poverty rates.     

文化马克思主义和现代文化研究

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…     

Biotechnology, Ethics and the Politics of Cloning

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.
