This article describes an unconventional participatory development approach carried out in an informal e‐waste hub in South‐West Hebron, an area that has collected and processed the bulk of Israeli e‐waste for over a decade. Our approach contributes to the critique and recovery of community representation in participatory development and the search for ways to facilitate representative community engagement. Specifically, we describe our use of a novel Delphi‐like method that allowed us to facilitate a broadly endorsed development trajectory within a heterogeneous and conflicted community. We show how the results yielded by this approach diverged from those that were likely to emerge from more facile forms of participation in ways that are important for other similar e‐waste hubs internationally, which face a destructive status quo on the one hand, or the economically ruinous international policies that ban e‐waste trade from “developed” to “developing” countries on the other. Despite real tensions and cleavages within the affected communities, the process described facilitated a shift from deadlocked environmental versus livelihood positions towards building capacity and regulating existing informal e‐waste trades to preserve livelihoods dependent on these. 相似文献

Most studies on the mobility of highly skilled migrants have been examined with a framework of global talent mobility and under conditions of neoliberal governance and economic globalization. In this study we challenge the notion of the hypermobile knowledge worker. Utilizing mixed methods, we examine the factors that attracted highly skilled migrants to Qatar and the conditions under which they might leave in the future. Rather than finding a group of footloose migrants attracted primarily to high-wage jobs, a lack of taxation or amenities, and with multiple alternative locations of residence, we find that highly skilled migrants exist on a spectrum of immobility. More significantly, this immobility depends on the migrant’s region of origin. For Asian and Western migrants immobility is attributed to the Kafala system or employer sponsorship, which hinders occupational and spatial mobility and ties workers to their sponsors. Arab highly skilled migrants are especially affected by lack of security and stability in their home countries, which makes these workers involuntarily immobile. The former group seem to be willing to accept a reduced level of agency and mobility for high income, whereas for the latter security and stability are more fundamental to their decision to come to Qatar. 相似文献

Standardization and decomposition are established and widely used demographic techniques for comparing rates and means between
groups with differences in composition. The difference in rates and means has heretofore been resolved in terms of the contribution
of variables to compositional effects for each variable and an overall rate effect. This study demonstrates that the resolution
of differences is attainable at the categorical level for both compositional effects and rate effects. Refinements to Das
Gupta’s equations yield a complete decomposition because of the additivity of categorical compositional and rate effects.
Other refinements allow the decomposition of polytomous variables. Extensions to the method provide for the decomposition
of the standard deviation and the multivariate index of dissimilarity. 相似文献

Death from pregnancy is rare in developed countries such as Australia but is still common in third world and developing countries. The investigation of each maternal death yields valuable information and lessons that all health care providers involved with the care of women can learn from. The aim of these investigations is to prevent future maternal morbidity and mortality.Obstetric haemorrhage remains a leading cause of maternal death internationally. It is the most common cause of death in developing countries. In Australia and the United Kingdom, obstetric haemorrhage is ranked as the 4th and 3rd most common cause of direct maternal death respectively. In a number of cases there are readily identifiable factors associated with the care that the women received that may have contributed to their death. It is from these identifiable factors that both midwives and doctors can learn to help prevent similar episodes from occurring.This article will identify some of the lessons that can be learnt from the recent Australian and UK maternal death reports. This paper presents an overview of the process and systems for the reporting of maternal death in Australia. It will then specifically focus on obstetric haemorrhage, with a focus on postpartum haemorrhage, for the 12-year period, 1994–2005. Vignettes from the maternal mortality reports in Australia and the United Kingdom are used to highlight the important lessons for providers of maternity care. 相似文献

This article reports on a social return on investment (SROI) analysis of volunteers of the Good Food Market program, a food access initiative run by FoodShare Toronto, one of Canada's largest food‐justice organizations. Unlike conventional SROI research, which typically focuses on the entire ecology of an organization or program, this article focuses solely on isolating the return volunteers receive on their investment of time, skills, energy, and the like—an SROI of volunteering. The article reviews the challenges of adapting the SROI methodology to the context of volunteer benefits and finds that ultimately SROI is a useful tool for articulating the value of volunteering. 相似文献

Since the 1990s the financialization of the enterprise is an increasingly important aspect of capitalist development also in Germany. However, more recently a growing number of scholars point at a problematic conceptual stretching of financialization. The term has been defined too differently and ambiguously and has not been distinguished sufficiently from seemingly similar concepts. Financialization has been prematurely identified with a set of fixed effects often condensed to stagist concepts of capitalist development. When analyzing effects financialization has been regarded in isolation without considering interaction effects with other structurations of fields and hence the multi-referentiality of the enterprise. In order to overcome these shortcomings the article proposes a concept for the analysis of firm level financialization which draws on a more general sociological concept of field structuration and dynamics in which the “multi-referential enterprise” operates. Based on this concept the article analyses episodes of financialization in Germany showing its dynamics and limits. Financialization of enterprises proves to be structurally limited, institutionally contested, and unfolds its effects in deferent actor constellations at firm level due to its multiple and contradictory embeddedness. 相似文献
