Across the world, governments are grappling with the effects of global warming. Rising temperatures, increases in the number of natural disasters, and elevated sea levels are just some of the risks posed by Earth's weakening ozone. And yet solutions exist. This article discusses the contribution of auto emissions to global warming and proposes ways for manufacturers to adopt a single emissions standard across their fleets all over the world. As discussed, adopting a single standard based on the most stringent one available poses advantages for manufacturers and also promises to reduce the threat of global warming.  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

In Australia, as elsewhere, cultural blindness to difference based on gender can affect the impartiality of judging. It is an important aspect of the unstated assumptions on which judges act and which they need to examine. This is especially so where the assumptions are a reflection of dominant social attitudes and values. Judges are expected to apply community values, so long as they are consistent with equality before the law. Blatant examples of gender bias tend to diminish as diversity increases, both within the judiciary and within the legal profession. Stereotyping assumptions can be explored through judicial education, but Australian experience suggests that programmes will only receive a receptive audience if sensitive to concerns about judicial independence. To that end, discussion may best be located within the boundaries of the broader topic of unconscious partiality. Steps being taken in New South Wales to raise gender sensitivity are noted.  相似文献

ABSTRACT

This article examines how three spheres of hostility intersect to prevent effective access to justice for those living with insecure immigration status. The neoliberal governance model, the barren justice landscape and the hostile environment are supported by the cynical construction of the ‘fat cat’ lawyer and the toxic ‘folk devil’ narrative of the ‘bogus’ asylum seeker. To the extent that the judiciary have frustrated the more obvious, ideologically driven, attempts to restrict access to justice for migrants, the austerity predicated measures pursuant to the Legal Aid, Sentencing and Punishment of Offenders Act 2012 (LASPO) have completely altered the legal landscape. The analysis is informed by the findings of the ‘Legal advice and support for persons with insecure status’ project (hereafter LAPIS) in Nottingham which explores the challenges faced by service providers and the lived experiences of those with insecurity of status. It is clear that access to justice is a passport to the realisation of other rights, yet participants struggled to access a remedy because legal advice is too often out of reach.  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

This article uses a multimethod research design to compare Statecraft to non-Statecraft assignments and courses along three dimensions: student engagement, political attitudes, and academic honesty. The results indicate that Statecraft increased student engagement and academic honesty. In terms of political attitudes, students generally remained on the left side of the political spectrum, but shifted toward the right and became more hawkish by the end of a semester. Changes in attitude are more strongly associated not with playing Statecraft, but taking a political science class by the coauthor, or some other external variable. Statecraft, however, did reduce support for pacifism.  相似文献

Since its beginnings, zoning has been at its core a tool for achieving exclusionary objectives. Judge Westenhaver, who wrote the lower court decision in Ambler Realty Co. u. Village of Euclid, 297 Fed. 307, 316 (N.D. Ohio 1924) invalidating the village's zoning ordinance, observed that its purpose “is really to regulate the mode of Living of persons who may here-after inhabit [the village]. In the last analysis, the result to be accomplished is to classify the population and segregate them according to their income or station in life.” In reversing his decision, Justice Sutherland classified apartments as “mere parasites … which would deprive children of the privilege of quiet and open spaces for play, enjoyed by those in more favored localities,” In effect, he held that the state's police power could be used to create different levels of health, safety and genera1 welfare for different classes of people. One level was adequate for the poor and another level could be enforced at the behest of the rich who could afford to buy homes in single-family, low-density districts. Even Justice Douglas, a most unlikely bedmate for Justice Sutherland, reflected the same attitude when he wrote recently.  相似文献
