Congress writes a law: Research and welfare reform

This paper traces the development of the Family Support Act of 1988 in the U.S. House of Representatives. The author, a Republican staff member, examines the impact of research on the policy environment that made welfare reform possible, on the arguments presented in committee hearings and bill-writing sessions, on the House debate, and on the final House/Senate Conference Committee approval. He concludes that social science research can and does play a useful role in formulation of public policy, although the domain of application is not as broad as many scholars think. However, given the partisan nature of policy formulation and the desire of social scientists to join the process, normal methods of quality control in social science research are too often forgotten, to the detriment of sound public decision-making.     

Slavery: a dual-equilibrium model with some historical examples

What sustains slavery, and why at critical junctures—the fall of the Roman Empire, the early modern expansion of plantation agriculture, the later phases of the industrial revolution, the totalitarian regimes of the 1930s—has it often expanded or contracted so rapidly? Why have elites sometimes been united, but sometimes violently divided, over the choice between free and servile labor? Why has slavery usually been ended by legal prohibition rather than voluntary abandonment? An extremely simple dual-equilibrium picture can illuminate how, when, and with whose support slavery is introduced or abolished. Internal divisions over slavery are likely to be most intense as a society approaches either of these “tipping points.” The most striking example, explored fleetingly here, is the US Civil War.     

The Financial Health of Political Parties in English Constituencies, 2004–05

Limited data have been available on the financial situation of the constituency branches of England's main political parties. Using recent annual accounts for all constituency parties with a turnover of £25,000 per annum or more in 2005, this paper reviews their financial health. It finds very little evidence of substantial financial turnover for the vast majority of local Labour parties and only a slightly better situation for the Liberal Democrats: many more local Conservative parties meet the reporting threshold but, even so, in almost half of all English constituencies none of the three parties reported a turnover of £25,000 or more. Local Conservative parties also differ substantially from the other two in their income sources and expenditure patterns.     

Rape and child sexual abuse: what beliefs persist about motives, perpetrators, and survivors?

Rape myths are prejudicial and stereotyped beliefs about rape which persist in society. They may have a significant impact on those affected by rape as well as the performance of legal and public participants in the justice system. Rape myths may differ over time and within different societies and cultural settings. Awareness of contemporary and local rape myths is necessary if they are to be successfully challenged through public campaigns and other means. This study sought to assess the prevalence of myths concerning rape and sexual abuse in a national population survey.     

Assessing a novel room temperature DNA storage medium for forensic biological samples

The ability to properly collect, analyze and preserve biological stains is important to preserving the integrity of forensic evidence. Stabilization of intact biological evidence in cells and the DNA extracts from them is particularly important since testing is generally not performed immediately following collection. Furthermore, retesting of stored DNA samples may be needed in casework for replicate testing, confirmation of results, and to accommodate future testing with new technologies.A novel room temperature DNA storage medium, SampleMatrix™ (SM; Biomatrica, Inc., San Diego, CA), was evaluated for stabilizing and protecting samples. Human genomic DNA samples at varying amounts (0.0625-200 ng) were stored dry in SM for 1 day to 1 year under varying conditions that included a typical ambient laboratory environment and also through successive freeze-thaw cycles (3 cycles). In addition, spiking of 1-4× SM into samples prior to analysis was performed to determine any inhibitory effects of SM. Quantification of recovered DNA following storage was determined by quantitative PCR or by agarose gel electrophoresis, and evaluation of quantitative peak height results from multiplex short tandem repeat (STR) analyses were performed to assess the efficacy of SM for preserving DNA.Results indicate no substantial differences between the quality of samples stored frozen in liquid and those samples maintained dry at ambient temperatures protected in SM. For long-term storage and the storage of low concentration samples, SM provided a significant advantage over freezer storage through higher DNA recovery. No detectable inhibition of amplification was observed at the recommended SM concentration and complete profiles were obtained from genomic DNA samples even in the presence of higher than recommended concentrations of the SM storage medium. The ability to stabilize and protect DNA from degradation at ambient temperatures for extended time periods could have tremendous impact in simplifying and improving sample storage conditions and requirements. The current work focuses on forensics analysis; however this technology is applicable to all endeavors requiring storage of DNA.     

Problem-based learning and international commercial dispute resolution in the Indian Ocean

One of the primary challenges for a law lecturer is to take students beyond their own assumptions about the parameters of a subject and provide them with new opportunities for exploration and a broader vision to enhance learning. A significant feature of law as a discipline of study in higher education that has the potential to impact on the curriculum and the way in which it is taught is the academic/vocational divide. Problem-based learning (PBL) activities make classroom settings unpredictable and surprising, and learning to deal with such uncertainty prepares students for one of the most crucial aspects of professional life: the ability to make judgements in a context of uncertainty. This article analyses the integration of PBL within an LLM module on International Commercial Dispute Resolution. The logic of using PBL in this module is to ensure that the more abstract and less engaging aspects of the course are learned in relation to a close involvement with problems that are highly relevant to students’ more concrete ideas of what the course is about and what competence would mean within it. The experience of the students with the PBL activities, captured in reflective narratives and anonymous questionnaires, is also discussed.     

AmpFlSTR profiler Plus short tandem repeat DNA analysis of casework samples, mixture samples, and nonhuman DNA samples amplified under reduced PCR volume conditions (25 microL)

As part of the validation of the AmpFlSTR Profiler Plus short tandem repeat (STR) system, under reduced polymerase chain reaction (PCR) volume conditions (i.e., 25 microL), a total of 275 casework samples were processed. Examples of profiles are presented along with amplification conditions to improve the odds of obtaining balanced and complete profiles for samples showing partial results or profiles with a descending slope. Data collected and used to develop our interpretation guidelines are included. From the mixture studies, full profiles were obtained for minor contributors, using 2 ng of DNA, with ratios of 10:1 or 1:20 and using 1 ng of DNA, with ratios of 10:1 and 1:8. The specificity of the Profiler Plus amplification reaction performed in 25 microL was examined and confirmed using a large spectrum of nonhuman DNAs. This report supports the use of the AmpFlSTR Profiler Plus STR system for casework DNA typing under reduced PCR volume conditions.
