This article examines the definition of success in First Nations drinking water service as voiced by the First Nations technical community of practice. The research explores success stories to identify success themes and factors to formulate a workable definition for policy‐makers. Researchers interviewed sixteen technical practitioners in Ontario using a semi‐structured approach. Data analysis revealed a definition of success that extends beyond the technical boundary to include professional growth, employment, local action and a facilitating policy environment. This comprehensive definition provides a basis for policy and program considerations to increase First Nations buy‐in and foster a constructive environment for drinking water improvements.  相似文献

Journalists were alarmed when, in 2005, the United States Court of Appeals for the Eleventh Circuit denied shield-law protection to Don Yaeger, an investigative reporter for Sports Illustrated, in a libel suit by fired football coach Mike Price. Yaeger is a journalist, and Alabama's shield law offers absolute protection even when a journalist is a party to a case. The court's decision turned on the fact that Alabama's seventy-three-year-old statute does not include the word “magazine.” This article shows that this hole in the “covered medium” language of Alabama's statute is not uncommon among the nation's thirty-six shield laws and that the Eleventh Circuit's strict reading of the statute's text is not at odds with current trends in statutory interpretation. Those two facts, combined with the rise of the Internet as an important vehicle for journalism, suggest the time is ripe to scrutinize and modernize shield laws, some of which have been on the books for more than a century.  相似文献

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

ABSTRACT

The present research examined the CSI Effect and the impact of DNA evidence on mock jurors and jury deliberations using a 3 (Crime Drama Viewing: low, moderate, high)?×?3 (Evidence: DNA innocent, DNA guilty, no DNA control) design. A sample of 178 jury-eligible college students read a case of breaking and entering. Pre-deliberation, some support for a CSI Effect was found with high viewers’ extent of guilt ratings significantly lower than moderate and low viewers’ in the no DNA control and the DNA innocent conditions. This effect was not present for verdicts. Contrary to a CSI Effect, crime drama viewing was not related to guilt judgments with incriminating DNA evidence. A content analysis of comments made during deliberations found little support for the CSI Effect entering the jury room. Specifically, CSI Effect predictions were not supported when examining the discussion of DNA evidence, expressing DNA opinions, or mentioning missing evidence. Overall, the limited CSI Effect found for individuals was attenuated during deliberation. The alarm raised over a possible CSI Effect influencing jury decision making may be unwarranted.  相似文献
