AbstractThis article draws on focus group conversations with black female college students attending a small, liberal arts institution in Kentucky. Based primarily on group interviews and discussions, as well as observations and analysis – a theoretical domain (referred to throughout the article as ‘Fabulachia’) emerged as a site-specific outcome of events and ideas regarding race, gender and identity experienced by the research participants. Specifically, ‘Fabulachia’ functions as a theoretical hybrid space in which urban (e.g. ‘ghetto fabulous’) black college student-voices find a sense of empowerment as they construct their own narratives of leaving ‘the hood’ to attend college in rural Appalachia. This project revises and updates previous research on race and rural identity/ies in order to situate the urban black female experience into an Appalachian context. Drawing on hip hop feminism and urban education based theoretical paradigms, the Fabulachia study seeks to give voice to black females in contemporary Appalachia, with attention to their self-proclaimed ‘ghetto fabulous’ identities honed in and through their urban upbringings. The unique experiences of (Fabulachian) black females are an important and largely absent part of larger conversations of the growing body of Urban education research that seeks to situate the black student/black youth and schooling experience in the US. In the Fabulachia study, a group of black female students shared personal narratives (part-oral history and part direct response) to prompts and queries about the role of hip hop culture, race and gender identity in their lives. They also discussed and debated what it means to be a black female in contemporary (often racist) Appalachia, and about how their families and urban surroundings influenced their processes of being and becoming in the context of higher educational achievement. 相似文献

Evaluation of multi-objective optimization approaches for solving green supply chain design problems
《Omega》2017
This paper evaluates the applicability of different multi-objective optimization methods for environmentally conscious supply chain design. We analyze a case study with three objectives: costs, CO2 and fine dust (also known as PM – Particulate Matters) emissions. We approximate the Pareto front using the weighted sum and epsilon constraint scalarization methods with pre-defined or adaptively selected parameters, two popular evolutionary algorithms, SPEA2 and NSGA-II, with different selection strategies, and their interactive counterparts that incorporate Decision Maker׳s (DM׳s) indirect preferences into the search process. Within this case study, the CO2 emissions could be lowered significantly by accepting a marginal increase of costs over their global minimum. NSGA-II and SPEA2 enabled faster estimation of the Pareto front, but produced significantly worse solutions than the exact optimization methods. The interactive methods outperformed their a posteriori counterparts, and could discover solutions corresponding better to the DM preferences. In addition, by adjusting appropriately the elicitation interval and starting generation of the elicitation, the number of pairwise comparisons needed by the interactive evolutionary methods to construct a satisfactory solution could be decreased. 相似文献

This paper is the first DEA (Data Envelopment Analysis) evaluation of the efficiency of a sample of mutual fund companies in a large Euro fund industry, i.e. Spain. Our novel network model links the efficiency of the core activities (portfolio management and marketing/distribution) of a mutual fund company to the efficiency of its operational management function. Our results highlight the important networking effects at the marketing stage and question the prime role of portfolio management skills in the overall efficiency of a mutual fund company. The evaluation of robust efficiency clusters indicates that the efficiency rankings obtained with our network model persist significantly along our sample period. Finally, the application of the SBM (Slacks-Based Measure) Variation III to our network model allows us to identify a large number of globally inefficient but locally efficient companies with reference to competitors with similar management resources. 相似文献

Since the Last Planner System® (LPS) was devised in the early 90s, a number of studies have pointed out the need to understand the underlying theory in which it is based on. The Language-Action Perspective (LAP) has been suggested as a suitable approach to understand the management of commitments in the LPS. This paper aims to assess the contribution of LAP to understand construction planning and control systems based on LPS. Two case studies were carried out in different construction companies, both highly experienced on the use of LPS. The results reveal the role of LAP for creating explicit representations of commitment flows that can be used to explain the sources of complexity and failures in planning systems, as well as for describing the profile of planning and control meetings. 相似文献

In the last decades, green and sustainable supply chain management practices have been developed, trying to integrate environmental concerns into organisations by reducing unintended negative consequences on the environment of production and consumption processes. In parallel to this, the circular economy discourse has been propagated in the industrial ecology literature and practice. Circular economy pushes the frontiers of environmental sustainability by emphasising the idea of transforming products in such a way that there are workable relationships between ecological systems and economic growth. Therefore, circular economy is not just concerned with the reduction of the use of the environment as a sink for residuals but rather with the creation of self-sustaining production systems in which materials are used over and over again.Through two case studies from different process industries (chemical and food), this paper compares the performances of traditional and circular production systems across a range of indicators. Direct, indirect and total lifecycle emissions, waste recovered, virgin resources use, as well as carbon maps (which provide a holistic visibility of the entire supply chain) are presented. The paper asserts that an integration of circular economy principles within sustainable supply chain management can provide clear advantages from an environmental point view. Emerging supply chain management challenges and market dynamics are also highlighted and discussed. 相似文献

Research highlights lasting cognitive and academic challenges in youth internationally adopted from institutional care. However, there is a lack of research examining internationally adopted students' sense of membership at school and associated academic and psychological outcomes. The current study measured sense of school membership and academic and psychological outcomes in post-institutionalized internationally adopted high school students (n = 29) compared to adolescents internationally adopted from foster care (n = 28) and non-adopted adolescents (n = 32). Post-institutionalized males had a lower sense of school membership than males adopted from foster care or non-adopted males. Group differences in school membership were mediated by academic achievement and psychological well-being. 相似文献

Social workers are better equipped to understand the need to incorporate geographical aspects pertaining to their clients’ lives as part of their practice, given the significant influence these factors have on client well-being. Geographic Information Systems (GIS) technology is a useful tool for administrators and planners to make informed decisions regarding human service programs including examining program outcomes and impact as well as streamlining program implementation. This article synthesizes the literature to date on GIS in health and human services with examples of real world applications. 相似文献

In this article, we define the concept of “risk work,” which aims to make visible working practices to assess or manage risk, in order to subject these practices to sociological critique. This article reviews and synthesizes existing published literature to identify components of risk work: (a) translating risk into different contexts, (b) minimizing risks in practice, and (c) caring in the context of risk. We argue that these three components of risk work raise important tensions for workers that have been inadequately explored in the literature to date. We propose that future research should additionally focus on practitioner subjectivity and identity in risk work. In addition, we argue that comparative research—across type of risk and different contexts—and methodological and theoretical diversity would enhance this emerging field of research. 相似文献
