The absence of a thoroughly developed, working class critique of criminological theory has resulted in bias in the creation
of knowledge regarding crime and deviance. Much as feminist writings illuminated the unique problems related to gender, and
works by those discussing racial and ethnic minorities highlighted the special concerns related to race and ethnicity, a working
class perspective can expose the particular issues having to do with class. A brief discussion will be presented dealing with
the portrayal of working class people in the media, and the complicity of academia in allowing working class stereotypes to
persist. A sketch of a working class perspective will then be developed, and it will be used to critique fourteen of the major
criminological theories today in terms of their relative sensitivities and considerations of the class factor in crime and
justice issues. The final section places each of the fourteen theories on a continuum from those that do not consider the
working class experience at all to those that give the working class experience full consideration.

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane. 相似文献

In the wake of the 1990 amendments to the Clean Air Act, localities across the United States initiated public information campaigns both to raise awareness of threats to air quality and to change behavior related to air pollution by recommending specific behavioral changes in the campaign messages. These campaigns are designed to reduce the health hazards associated with poor air quality and to avoid federal sanctions resulting from the failure to meet air quality standards. As in many other communities across the country, a coalition of government agencies and businesses initiated a public information campaign in the Atlanta metropolitan region to reduce certain targeted behaviors, mainly driving. A two‐stage model used to analyze data from a rolling sample survey shows that the centerpiece of the information campaign—air quality alerts—was effective in raising awareness and reducing driving in a segment of the population. When the overall information campaign was moderated by employers' participation in programs to improve air quality, drivers significantly reduced the number of miles they drove and the number of trips they took by car on days when air quality alerts were sounded. Public information campaigns can be successful in increasing awareness, but changing well‐established behaviors, such as driving, is likely to require institutional mediation to provide social contexts that support the behavioral change, as well. © 2003 by the Association for Public Policy Analysis and Management. 相似文献

Report of an unusual finding of bones on the shore of the Baltic Sea. Although the morphological findings appeared similar to a human foot skeleton, a quick identification as sea dog bone was possible. 相似文献

We report a case of rapid death from thrombotic thrombocytopaenic purpura (TTP) in a young pregnant lady who developed full blown symptoms soon after caesarean section. Extensive intramyocardial confluent haemorrhages and widespread microthrombi in heart, brain, adrenals and kidney were found at autopsy. Thrombotic thrombocytopaenic purpura is an uncommon condition, which carries a high fatality rate if untreated. Awareness of this syndrome together with its high risk of sudden death underlines the importance of rapid diagnosis and treatment. 相似文献

Conclusion So can the Scots learn from Woolf? The answer must be in the affirmative, for his review points up similar problems to those
we encounter here. There is no room for complacency in the civil justice system in Scotland, particularly in the field of
Information Technology, where court systems and expertise are sadly lacking. It is clear that there is a need for a system
of case management in all civil courts, targeted in particular areas or on particular cases, but only after a rigorous reappraisal
of court timetabling; and that the public will lose confidence in a civil justice system which does not meet their needs for
speedy and affordable decisions, perhaps by turning their backs on it and seeking means of Alternative Dispute Resolution.
As for written pleadings, perhaps the most that can be said is that the case for their complete abolition is “not proven”,
but that thestatus quo should not be maintained is beyond reasonable doubt.
