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

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

Experiences with racism are a common occurrence for African American youth and may result in negative self perceptions relevant
for the experience of depressive symptoms. This study examined the longitudinal association between perceptions of racism
and depressive symptoms, and whether perceived academic or social control mediated this association, in a community epidemiologically-defined
sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling revealed that experiences with racism were associated with low perceived
academic control, which in turn was associated with increased depressive symptoms. Findings suggest that experiences with
racism can have long lasting effects for African American youth’s depressive symptoms, and highlight the detrimental effects
of experiences with racism for perceptions of control in the academic domain. Implications for intervention are discussed.
