We investigate the performance of capacity-sensitive order review and release (ORR) procedures in job shop environments that have not been previously explored. Previous research has ignored the case of job shops which must perform to very tight due-dates because of time-sensitive customers. We propose and test a new capacity sensitive ORR procedure called path based bottleneck (PBB) in such environments, along with the modified infinite loading (MIL) procedure which has been shown to work well in several studies. We compare the performance of these two controlled release rules with that of immediate release rule under different conditions of capacity utilization and customer specified exogenous duedates. Our results indicate that PBB performs well in lowering total costs when due-dates are tight, while MIL is a better procedure with relatively loose to medium due-dates. We also show that in many cases, the shortest processing time (SPT) dispatching rule is a superior performer than a due-date based rule like critical ratio (CR); a conclusion which is contrary to the existing research in this area. In addition, the shop floor control policies recommended are shown to be sensitive to the cost structure of the firm. The managerial implications of this research in providing effective shop floor control in job shops operating under tight due-date conditions are also discussed.  相似文献

This piece of writing is a joint initiative by the participants in the Gender, Work and Organization writing workshop organized in Helsinki, Finland, in June 2019. This is a particular form of writing differently. We engage in collective writing and embody what it means to write resistance to established academic practices and conventions together. This is a form of emancipatory initiative where we care for each other as writers and as human beings. There are many author voices and we aim to keep the text open and dialogical. As such, this piece of writing is about suppressed thoughts and feelings that our collective picket line allows us to express. In order to maintain the open‐ended nature of the text, and perhaps also to retain some ‘dirtiness’ that is essential to writing, the article has not been language checked throughout by a native speaker of English.  相似文献

This article focuses on unlikely movement actors whose civic engagement has been understudied: people with criminal records (“returning citizens”). We present findings from 18 months of ethnographic research with members (leaders) of Fighting to Overcome Records and Create Equality (FORCE), a civic group led by returning citizens. FORCE leaders received institutional support from Community Renewal Society (CRS), a larger faith and community-based organization, to lead a rights reform movement in Chicago. Findings suggest that FORCE leaders constructed notions of kinship, recognition, and power through civic capacity-building efforts—and that social belonging was core to such capacity-building efforts. While bonding social belonging occurred as FORCE leaders formed kinship with people facing similar social and economic marginality, bridging social belonging emerged as leaders felt recognized by CRS staff organizers, affiliates, and elected officials. Bonding and bridging social belonging enabled FORCE leaders, who faced constant social exclusion in society, to experience much needed kinship, recognition, and power. Future studies should continue to uncover how local capacity-building processes have life-changing relational effects on movement participants from socially and economically marginalized groups.  相似文献

In this content analysis, researchers examine articles published from 2000 to 2015 in three family therapy journals, yielding a total of 948 empirical articles. The purpose is to provide an overview of the research being published, assess who is publishing, and investigate the current state of clinical effectiveness research in marriage and family therapy (MFT). Most first authors were affiliated with MFT programs and primarily included diversity and couples in their research. There was a significant increase of research on clinical process—though the number of clinical outcome studies held steady. There were no significant changes with regard to research funding. Implications support the use of innovative research methods to provide evidence of clinical effectiveness.  相似文献

Objective: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. Participants: Participants were 526 young adults aged 18–23 (n?=?355 4-year students; n?=?171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Methods: Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. Results: Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Conclusions: Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students.  相似文献

Experiential learning theory suggests that students increase their understanding when given the opportunity to experience a particular situation in addition to learning about it intellectually. This theory was used to construct an assignment to assist social work master’s students in better understanding food insecurity and the Supplemental Nutrition Assistance Program (SNAP). Through coding previously collected reactions to the assignment, the researchers discovered multiple reoccurring themes: increased understanding of SNAP, feelings about the program, realizations regarding individual privilege, client stigma, the social experience of eating, and empathy for those who experience food insecurity. Through this exercise, students increased their knowledge of the program and also gained a better understanding of how food insecurity personally affects individuals and families.  相似文献

全球化与贫穷之间有何联系?发展中经济体长期以来一直将国际贸易和金融作为发展的解决方案,但全球35%的人口仍生活在国际贫困线以下。经济学家和政治学家探究了这种联系,但仍未得出结论。我们回顾了相关文献,认为要理解全球化与贫穷之间的联系,我们必须根本理解针对最贫困人口政策背后的政治动机。具体来说,我们主张学者需要明确发展中国家政府的意识形态立场,这一认同超越了发达国家主流的传统左右翼分歧的观点。我们为学者在全球范围内如何开始推动意识形态起作用以及为什么必须评估全球化与贫穷的联系提供了理论指导。此外,我们还对我们的论点提供了初步的定量和定性检验。最后,两个学科的学者为了评估贸易与贫穷之间的联系,必须开始评估政府对扶贫再分配的承诺(而不是受制于既得精英利益集团的政策)。  相似文献

Common Ground Co‐operative (CGC) provides training, administrative, and job coach support to five social enterprises for which persons with developmental disabilities are the non‐share‐capital partners. This study examines the use of social return on investment (SROI) as a means of determining the value of program impacts related to quality‐of‐life changes for enterprise partners and their families. The process of conducting this SROI analysis is described and analyzed in terms of its utility in employment services for persons with developmental disabilities.  相似文献
