Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.     

Seeking or controlling the truth? An examination of courtroom questioning practices by Canadian lawyers*

ABSTRACT

The questioning practices of Canadian lawyers were examined. Courtroom examinations (N?=?91) were coded for the type of utterance, the assumed purpose of the utterance, and the length of utterance. Results showed that approximately one-fifth of all utterances were classified as productive for gathering reliable information (i.e. open-ended, probing); less than one percent of all utterances were open-ended. Direct examinations contained more closed yes/no, probing, and open-ended questions. Cross-examinations contained more leading and clarification questions, and opinions. Moreover, cross- (vs. direct) examinations contained more questions with a ‘challenging the witness’ purpose. The longest utterances were opinions, followed by multiple and forced-choice questions. The longest answers were in response to open-ended questions, followed by multiple and probing questions. Implications for the truth-seeking function of the judiciary are discussed.     

Evaluating the Effectiveness of Adopting Open Educational Resources in an Introductory American Government Course

In this article, we present findings from a grant-funded initiative to replace traditional, proprietary textbooks with an open content textbook under a Creative Commons license in the introductory American government course (POLS 1101) at Middle Georgia State University. We find that the use of an open content textbook led to somewhat negative effects on student learning outcomes and student course satisfaction, although the associated lower textbook cost increased textbook accessibility to students. We conclude with some suggestions to those adopting textbooks in this course and to the wider discipline regarding measures that may lead to more unequivocally positive outcomes than those experienced in this study.     

Crafts and trades (english): Comment on T. Shanin

Eric Hobsbawm's outline of the concept of social banditry suggest certain conditions of existence for that mode of primitive rebellion. Primary among these conditions are the presence of a ‘traditional peasant environment and the absence of ‘industrial capitalism’. This paper presents a critique of Hobsbawm's specifications, and suggest two alternative conditions: the presence of class conflict which unites direct producers, and the absence of effective, institutionalised political organisation of producers’ interests. This reformulation is illustrated by reference to the Kelly Outbreak in late nineteenth century Australia.     

Predicting Children’s Depressive Symptoms from Community and Individual Risk Factors

Community, demographic, familial, and personal risk factors of childhood depressive symptoms were examined from an ecological theoretical approach using hierarchical linear modeling. Individual-level data were collected from an ethnically diverse (73% African-American) community sample of 197 children and their parents; community-level data were obtained from the U.S. Census regarding rates of community poverty and unemployment in participants’ neighborhoods. Results indicated that high rates of community poverty and unemployment, children’s depressive attributional style, and low levels of self-perceived competence predict children’s depressive symptoms, even after accounting for demographic and familial risk factors, such as parental education and negative parenting behaviors. The effect of negative parenting behaviors on depressive symptoms was partially mediated by personal variables like children’s self-perceived competence. Recommendations for future research, intervention and prevention programs are discussed.

Empowerment,Deliberative Development,and Local-Level Politics in Indonesia: Participatory Projects as a Source of Countervailing Power

The salience of the concept of “empowerment” has been deductively claimed more often than carefully defined or inductively assessed by development scholars and practitioners alike. We use evidence from a mixed methods examination of the Kecamatan (subdistrict) Development Project (KDP) in rural Indonesia, which we define here as development interventions that build marginalized groups’ capacity to engage local-level governing elites using routines of deliberative contestation. “Deliberative contestation” refers to marginalized groups’ practice of exercising associational autonomy in public forums using fairness-based arguments that challenge governing elites’ monopoly over public resource allocation decisions. Deliberative development interventions such as KDP possess a comparative advantage in building the capacity to engage because they actively provide open decision-making spaces, resources for argumentation (such as facilitators), and incentives to participate. They also promote peaceful resolutions to the conflicts they inevitably spark. In the KDP conflicts we analyze, marginalized groups used deliberative contestation to moderately but consistently shift local-level power relations in contexts with both low and high preexisting capacities for managing conflict. By contrast, marginalized groups in non-KDP development conflicts from comparable villages used “mobilizational contestation” to generate comparatively erratic shifts in power relations, shifts that depended greatly on the preexisting capacity for managing conflict.
