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

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

Peers and bystanders play important roles in organizational and community conflict management. Bystanders often learn relevant information and have opportunities to act in ways that can affect three of the basic functions of a conflict management system (CMS.) They can help (or not help) to identify, assess, and manage behaviors that the organization or community deems to be “unacceptable.” Examples in which bystanders play important roles include sexual and racial harassment, safety violations, unethical research, national security violations and insider threats, cyber‐bullying and cyber‐sabotage, violence, fraud, theft, intimidation and retaliation, and gross negligence. Bystanders often are a missing link in conflict systems. For the purposes of this article, I define peers and bystanders as people who observe or learn about unacceptable behavior by others, but who are not the relevant supervisors, or who knowingly engage in planning or executing that behavior. I define CMS managers as all those people, including line managers, who have responsibility for managing conflicts. Conflict managers face many challenges in fostering constructive behavior from bystanders. The interests of bystanders may or may not coincide with the interests of conflict systems managers in an organization or community. Bystanders often have multiple, idiosyncratic, and conflicting interests, and experience painful dilemmas. In addition, peers and bystanders, and their contexts – often differ greatly from each other. Blanket rules about how all bystanders should behave, such as requirements for mandatory reporting, are often ineffective or lead to perverse results. Bystanders are regularly equated with “do‐nothings,” in the popular press. In real life, however, helpful bystander actions are common. Many bystanders report a wide variety of constructive initiatives, including private, informal interventions. In this article, I report on forty‐five years of observations on bystanders in many milieus. I present what bystanders have said are the reasons that they did not – or did – take action, and what can be learned to help organizations and communities to support bystanders to be more effective when faced with unacceptable behavior.  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

Despite domestic opposition and several policy alternatives, in 2001 the Russian government adopted a pension reform that was potentially costly and had uncertain long-term benefits. Demographic and fiscal pressures created the desire to reform and a more cooperative Duma made it possible to do so. These points do not explain why Putin chose the pension privatisation option. Russia's pension reform is best understood as part of a state-building strategy to diminish the role of powerful bureaucracies. Russia's welfare state was not merely the product of a powerful and popular president, but rather a tool to create a stronger executive.  相似文献

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

Objectives

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.
