This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks. 相似文献
While block randomized designs have become more common in place-based policing studies, there has been relatively little discussion of the assumptions employed and their implications for statistical analysis. Our paper seeks to illustrate these assumptions, and controversy regarding statistical approaches, in the context of one of the first block randomized studies in criminal justice—the Jersey City Drug Market Analysis Project (DMAP).
Methods
Using DMAP data, we show that there are multiple approaches that can be used in analyzing block randomized designs, and that those approaches will yield differing estimates of statistical significance. We develop outcomes using both models with and without interaction, and utilizing both Type I and Type III sums-of-squares approaches. We also examine the impacts of using randomization inference, an approach for estimating p values not based on approximations using normal distribution theory, to adjust for possible small N biases in estimating standard errors.
Results
The assumptions used for identifying the analytic approach produce a comparatively wide range of p values for the main DMAP program impacts on hot spots. Nonetheless, the overall conclusions drawn from our re-analysis remain consistent with the original analyses, albeit with more caution. Results were similar to the original analyses under different specifications supporting the identification of diffusion of benefits effects to nearby areas.
Conclusions
The major contribution of our article is to clarify statistical modeling in unbalanced block randomized studies. The introduction of blocking adds complexity to the models that are estimated, and care must be taken when including interaction effects in models, whether they are ANOVA models or regression models. Researchers need to recognize this complexity and provide transparent and alternative estimates of study outcomes.
This essay investigates the political economy of sexuality through an interpretation of sex shows for foreigners in Bangkok,
Thailand. Reading these performances as both symptoms of, and analytical commentaries on, Western consumer desire, the essay
suggests the ‘pussy shows’ parody the mass production that was a hallmark of Western masculine identity under Fordism. This
reading makes a case for the erotic generativity of capitalism, illuminating how Western, post-Fordist political economy of
the post-1970s generated demand for these erotic services in Asia and how Western, heterosexual masculine desire is integrated
into global capitalist circuits. 相似文献
This article explores the contradictions of corporate-aided social provisioning and shows how such contradictions impact on social existence in three oil- and gas-producing communities in Nigeria. It is based in part on the findings of the author's ethnographic work in the three communities. The analysis extends the growing scholarly debate that when the state abandons its developmental obligations to the citizenry, and business voluntarily steps into the centre stage of social provisioning by way of corporate citizenship, the resulting interventions could have profound counter-developmental consequences, especially at the grassroots. 相似文献
Research examining correctional officer perceptions about the sexual victimization of inmates is rare. This research offers a first glimpse of what personal, job-related, and attitudinal factors influence blaming incarcerated sexual assault victims among a sample of 376 jail correctional officers in one state. Surveys are utilized to elicit understanding about officer perceptions of incarcerated victims. Findings indicate that jail correctional officer blaming of incarcerated sexual assault victims is highly correlated with perceptions about rape myths and homosexuality. Specifically, officers who adhere to rape myths and disapprove of homosexuality are more likely to blame incarcerated victims of sexual assault. This study is a first to examine factors correlated with jail correctional officer blaming of incarcerated sexual assault victims. The results are useful in understanding the perspectives of jail correctional officers and experiences of victims incarcerated in jails. Implications for correctional institutions and authorities include attending to the issue of sexual assault in correctional facilities, understanding staff perceptions that are related to this issue, training of staff, and classification of inmates. 相似文献
Spoilers of peace agreements are normally seen as motivated by utility maximization, their actions intended to gain a larger proportion of postconflict political power or economic wealth. In this article, I examine this perspective via a comparative analysis of two cases of spoiler violence in Assam, India, one involving a spoiler excluded from the agreement and the other a spoiler central to the peace process and the postconflict political and economic milieu. Both cases suggest that some spoiling action following peace agreements is less instrumental and driven more by emotional and ideological phenomena than this leading understanding suggests. 相似文献
As Britain's industrial economy matured and the volume of administrative work increased, different kinds of clerical jobs and clerical careers became possible. Using examples from a variety of small- to medium-sized enterprises in Glasgow, this article will describe how the main functions of administrative work – financial, secretarial and managerial – were divided both horizontally and vertically in order to preserve secure, well-paid, ‘breadwinning’ jobs for men, leaving routine secretarial work for women. The isolation of women in all-women enclaves carrying out shorthand and typing work and the subsequent devaluation of these as kinds of work were of primary importance in the creation of office work that was explicitly women's work 相似文献
A case study of the Mozambican conflict is used to illustrate the need to integrate a gender perspective which is historically grounded and which encompasses social relationships between women and men rather than the existing 'impact of conflict on women' approach. This is demonstrated first by examining ways in which postcolonial states have continued constructions of gender which assign women to the private/domestic sphere and then by establishing how security in Southern Africa has been mediated by gendered constraints, whether in peace or war. The specific character of the Mozambican conflict is summarised, as are its outcomes in terms of gender relations which have intensified women's vulnerability. This is then related to an examination of the nature of some of the major humanitarian responses to the Mozambican emergency, where there was a wide divergence between stated policies on gender and practice. It is argued that this 'gender gap' is being perpetuated in some aspects of the reconstruction phase, despite women's enormous contribution to the task of rebuilding Mozambican society. 相似文献
