This article proposes a new approach to investigating the substance of lawmaking. Only a very small proportion of bills become law in the U.S. Congress. However, the bills that do become law often serve as vehicles for language originating in other bills. We investigate “text reuse” methods as a means for tracing the progress of policy ideas in legislation. We then show how a focus on policy ideas leads to new insights into the lawmaking process. Although our focus is on relating content found within bills, the same methods can be used to study policy substance across many research domains. 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

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. 相似文献

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. 相似文献

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.
Dr. Danielle H. Dallaire is an Assistant Professor in the Psychology Department at The College of William and Mary. She received her Ph.D. from Temple University in 2003. Her major research interests include children’s social and emotional development and promoting resiliency in children and families in high risk environments, particularly children and families dealing with parental incarceration. Dr. David A. Cole is a Professor in the Department of Psychology and Human Development at Vanderbilt University. He received his Ph.D. from The University of Houston in 1983. His major research interests center around developmental psychopathology in general and childhood depression in particular. Dr. Thomas M. Smith is an Assistant Professor of Public Policy and Education at Vanderbilt University, Peabody College. He received his Ph.D. in 2000 from The Pennsylvania State University. Professor Smith’s current research agenda focuses on the organization of teaching quality, exploring relationships between educational policy (national, state, district, and school level), school organization, teacher commitment, and the quality of classroom instruction. Dr. Jeffrey A. Ciesla is an Assistant Professor in the Psychology Department at Kent State University. He received his Ph.D. from The State University of New York at Buffalo in 2004. His major research interests include the effects of ruminative thought and stressful life events on depressive disorders. Beth LaGrange, M.S., is a Doctoral candidate in Clinical Psychology in the Department of Psychology and Human Development at Vanderbilt University. Her current research interests include depression and the development of depressive cognitive style in children and adolescents. Dr. Farrah M. Jacquez is a Postdoctoral fellow in pediatric psychology at the Mailman Center for Child Development at the University of Miami. She received her Ph.D. from Vanderbilt University in 2006. Her major research interests include parenting in the context of poverty and developing community-based interventions for underserved children and families. Ashley Q. Pineda, M.S., is a Doctoral candidate in Clinical Psychology in the Department of Psychology and Human Development at Vanderbilt University and is currently completing her internship at the Children’s Hospital at Stanford University. Her major research interests include examining the reciprocal relations between parenting behaviors, depressive cognitions, and childhood depression. Alanna E. Truss, M.S., is a Doctoral candidate in the Department of Psychology and Human Development at Vanderbilt University. Her major research and clinical interests include developmental factors in internalizing disorders in children and adolescents and the effects of trauma on children and families. Amy S. Folmer is a graduate student in the Department of Psychology and Human Development at Vanderbilt University. She received her B.A. from The University of Texas in 2003.
