Allocating projects to project managers (PM) is a crucial decision in project management. Choosing the PM must be undertaken in a structured way, and thereby take into account the needs of the project and the PM’s competences and availability. The proposed model optimises the total time that PMs have available and takes into account the constraint of the switchover time loss within the mathematical programming. It model is part of a three-stage approach where: (1) projects are sorted using a multicriteria approach; (2) PMs are sorted using a multicriteria approach; and (3) the final allocation to intra-classes of projects is made using the optimisation model. This proposal contributes to aiding decision-makers involved in allocating projects: by respecting the limit of the time that PMs have available, or by extrapolating PMs’ available hours in which case overtime will have to be used. The model is applied in a Brazilian Energy Company. 相似文献

In 2013, academics from a Scottish university came together with social work managers and practitioners from two local authorities (LAs) in Scotland to run a knowledge exchange (KE) project co‐sponsored by the Economic and Social Research Council and the LAs. The project's aim was an ambitious one: to contribute to culture change in the children and families' departments in the two partner agencies. The project grew out of an earlier KE venture that had explored ways of engaging better with involuntary service users in social work; it thus both anticipated and reflected wider concerns about services for children that were also demonstrated in Munro's Review of Child Protection. The KE project had three components: training for managers, practitioner research projects and critical reflection workshops. Whether, and to what degree, the KE project changed culture is not the focus of this paper, which is written jointly by academic researchers and practitioners. Instead, one element of the KE project, namely the critical reflection workshops, is discussed. Findings provide strong evidence of the pressures currently experienced by children and families' services in the UK public sector. They also indicate how important good relationships are in building meaningful KE. 相似文献

Much of the debate on flexibility has remained at a stubbornly macro, demographic level without looking closely at individual attempts to become more flexible. This paper argues that the debate on flexibility has been dominated by attention to the structural side, looking at flexi-time and part-time contracting, for example, to the neglect of what we call self-flexibility through self-reflexivity and self-transformation. The paper begins to redress this imbalance drawing upon two different cases which examine specific forms of self-flexibility: feedback and personal malleability and risk-taking through experiential learning. Drawing upon sociological research, we seek to examine critically the ways in which self-flexibilities are taken up and pursued by employees in their attempts to remain employable and their gendered implications. 相似文献

This essay is written from the perspective of a doctoral student in sociology who through experience became aware of a critical
gap between worlds of practice and academia. My experiences reconfirm the view that applied and academic orientations are
not antithetical but rather complimentary components of a realistic and integrated view of society. The pro-active position
of this essay states that a student who sincerely seeks a comprehensive education will take the responsibility of seeking
exposure to a broad range of opportunities which will provide the skills and insights necessary to contribute substantially
to the future of sociology. 相似文献

This article presents a general model for estimating population heterogeneity and "lack of knowledge" uncertainty in methylmercury (MeHg) exposure assessments using two-dimensional Monte Carlo analysis. Using data from fish-consuming populations in Bangladesh, Brazil, Sweden, and the United Kingdom, predictive model estimates of dietary MeHg exposures were compared against those derived from biomarkers (i.e., [Hg]hair and [Hg]blood). By disaggregating parameter uncertainty into components (i.e., population heterogeneity, measurement error, recall error, and sampling error) estimates were obtained of the contribution of each component to the overall uncertainty. Steady-state diet:hair and diet:blood MeHg exposure ratios were estimated for each population and were used to develop distributions useful for conducting biomarker-based probabilistic assessments of MeHg exposure. The 5th and 95th percentile modeled MeHg exposure estimates around mean population exposure from each of the four study populations are presented to demonstrate lack of knowledge uncertainty about a best estimate for a true mean. Results from a U.K. study population showed that a predictive dietary model resulted in a 74% lower lack of knowledge uncertainty around a central mean estimate relative to a hair biomarker model, and also in a 31% lower lack of knowledge uncertainty around central mean estimate relative to a blood biomarker model. Similar results were obtained for the Brazil and Bangladesh populations. Such analyses, used here to evaluate alternative models of dietary MeHg exposure, can be used to refine exposure instruments, improve information used in site management and remediation decision making, and identify sources of uncertainty in risk estimates. 相似文献

There is a very strong trend in American culture to impute fixed, stable, and universal properties to a wide range of behaviors and conditions, thereby essentializing their qualities and locating them within nature. Both persons with disabilities and queers have been designated as nature's deviants. The author explores parallels and points of divergence in the responses of both disability rights and queer rights activism and scholarship to this assigned classification. She further illuminates this exploration by drawing upon insights derived from growing up with a congenital disability. As a child, the author felt that her body was a text composed, crafted, and edited by those who had the power to manipulate it. Recently, she entered a lesbian relationship, and together she and her partner planned a commitment ceremony that allowed her to reclaim her own body, because the body of the text that ensued was one of their own creation. 相似文献

We wanted to prospectively evaluate the use of a brief screening tool for ongoing intimate partner violence (IPV), the OVAT, and to validate this tool against the present Index of Spouse Abuse (ISA). The design was a prospective survey during randomized 4-hour shifts in an urban emergency department setting. The scale consists of four questions developed based on our previous work. The ISA was compared as the gold standard for detection of present (ongoing) IPV. Of 362 eligible patients presenting during 75 randomized 4-hour shifts, 306 (85%) completed the study. The prevalence of ongoing IPV using the OVAT was 31% (95% CI 26% to 36%). For the ISA, the prevalence was 20% (95% CI 16% to 25%). Compared with the ISA, the sensitivity of the OVAT in detecting ongoing IPV was 86%, specificity 83%, negative predictive value 96%, positive predictive value 56%, with an accuracy of 84%. In conclusion, four brief questions can detect ongoing IPV to aid in identifying the victim. 相似文献

This chapter examines the role of a national network of local and regional intermediary organizations in initiating and sustaining community-based youth worker professional development systems. This approach is instructive for other intermediaries in establishing training standards, assessing impact, providing organizational supports for youth development workers, and going to scale. 相似文献

In this article we present two sets of empirical analyses that consider the extent to which socioeconomic gradients in self-assessed health and child mortality changed since the beginning of the twentieth century in the United States. This empirical issue has important and wide-ranging research and policy implications. In particular, our results speak to the value of considering the role of broader social, economic, and political inequalities in generating and maintaining socioeconomic disparities in morbidity and mortality. Despite dramatic declines in morbidity and mortality rates in the United States across the twentieth century, we find that socioeconomic-status gradients in morbidity and mortality declined only modestly (if at all) during that period. 相似文献

The risks which children run from other children in substitute care have received little attention. However, if children's safety in care is to be maximized, then placement planning will need to focus on the risks and vulnerability of both the child to be placed and others already in the setting. It should also ensure that full information is given to the caregivers. In an interview sample of 40 looked after sexually abused and/or abusing young people aged 10 or over, most of the young abusers were placed in foster care and the majority of the sexually abused young people went into children's homes. However, in fewer than a third of these placements was consideration given to how the young person would fit in with others in that setting. This meant that the potential risks which that child posed to others or vice versa were not addressed. More worrying still, in just under half of the sample, no information about the young person's history of sexual abuse or abusing behaviour was given to the caregivers. This meant that caregivers were unable to plan to provide the level of supervision which might have averted a number of instances of abuse. When the whole histories of the sexually abused young people in the study were examined, it was found that half of them had abused another child at some stage, generally another child in care. This evidence suggests that the experience of sexual abuse should be regarded as an important risk factor in the later development of sexually abusing behavior and that local authorities need to fashion policies which emphasize the prime importance of social workers providing full information about children's backgrounds when placements are made.
