This study examines the way in which Shared Services Centers (SSCs) were implemented in a French multinational company. It aims to characterize the change according to the capabilities model developed by Amartya Sen: what are the effects of SSCs in terms of capabilities development and developmental quality of work, i.e. in the enabling potential of work? A 3-step methodology has been used: first, an investigation was conducted in a pay service of a local entity moving into SSC in 2013; second, two investigations were conducted in another pay service of a SSC: first, a few months after the change, and then, one year after the change (the same operators were interviewed). Results show a tendency to the decrease of the enabling potential. Additionally, it was noted that administrators are kept away from the design process and have to struggle with inappropriate rules. The efficiency and sustainability of the SSC are questioned; in this context, the human factor specialist has an important role to play.  相似文献

Proper body support plays an import role in the recuperation of our body during sleep. Therefore, this study uses an automatically adapting bedding system that optimises spinal alignment throughout the night by altering the stiffness of eight comfort zones. The aim is to investigate the influence of such a dynamic sleep environment on objective and subjective sleep parameters. The bedding system contains 165 sensors that measure mattress indentation. It also includes eight actuators that control the comfort zones. Based on the measured mattress indentation, body movements and posture changes are detected. Control of spinal alignment is established by fitting personalized human models in the measured indentation. A total of 11 normal sleepers participated in this study. Sleep experiments were performed in a sleep laboratory where subjects slept three nights: a first night for adaptation, a reference night and an active support night (in counterbalanced order). Polysomnographic measurements were recorded during the nights, combined with questionnaires aiming at assessing subjective information. Subjective information on sleep quality, daytime quality and perceived number of awakenings shows significant improvements during the active support (ACS) night. Objective results showed a trend towards increased slow wave sleep. On the other hand, it was noticed that % N1-sleep was significantly increased during ACS night, while % N2-sleep was significantly decreased. No prolonged N1 periods were found during or immediately after steering.  相似文献

Protecting and conserving environmental resources is a global concern. Over the past decade, a number of certification processes have emerged to help designers and operators of buildings assess the potential impact of a building on the environment. Certifications such as the Leadership in Energy and Environmental Design (LEED) consider the environmental impact through the lifecycle of a building, but may not be considering the people that construct and utilize it. It is important to remember the human factor. Considering the human factor throughout the lifecycle is crucial to ensure individuals are protected during construction and in operation in the built environment. The paper highlights how ergonomics can be integrated into the life cycle of a building to promote sustainability goals for both the human factor and the environment. A case study approach will be used to illustrate how ergonomics was integrated into a LEED renovation and expanded into its daily operations on a large university campus..  相似文献

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.  相似文献

Most American youth hold a job at some point during adolescence, but should they work? This article presents a broad overview of teenage employment in the United States. It begins by describing which teenagers work and for how long and then focuses attention on the consequences (both good and bad) of paid work in adolescence. It then presents recent nationally representative data from the Monitoring the Future Study suggesting that limited hours of paid work do not crowd out developmentally appropriate after-school activities. A review of the literature also supports the idea that employment for limited hours in good jobs can promote career readiness and positive development. The article concludes with a discussion of the implications of youth work for practitioners and policymakers who are delivering career-related programming.  相似文献

This article provides a comprehensive overview of the Hmong in America and encompasses their mental health status for the past 35 years. Since their mass arrival to the United States in 1975, limited research has been compiled to track the specific mental health issues that affect this collective community alone. Major chronological research findings were compiled for this article and specific findings concerning the Hmong and their mental health issues were compared to findings for other Southeast Asian groups. In conclusion, the findings of this article indicate that the Hmong still have higher rates of being diagnosed with depression, the lowest help-seeking behaviors in utilizing Western medicine, and the lowest arithmetic average of "happiness" scaled on an assessment tool. The purpose of this article is to better steer future research projects that entail tracking and differentiating the specific mental health domains of the Hmong.  相似文献

Despite a re-evaluation of risks in recent years, hormone replacement therapy is still surrounded by controversy. Almost 30% of women in a recent survey sought a natural approach to combat climacteric symptoms. Nevertheless, a large proportion of patients felt that they wanted a good safety profile and strong evidence base for treatment. This article seeks to review the evidence supporting non-hormonal approaches to treatment. There is only conflicting evidence at best to support alpha-2 agonists, e.g. clonidine and limited evidence for dihydroepiandrosterone and natural progesterones. There is limited randomized controlled trial data for gabapentin, selective norepinephrine re-uptake inhibitors (SNRIs) and selective serotonin re-uptake inhibitors (SSRIs), many of these studies being related to breast cancer patients. Of the herbal medicinal products, the largest evidence base rests with phytoestrogens. A Cochrane Database review looking at all types of phytoestrogens, e.g. red clover extracts, dietary soya and soya extracts concluded that there was no evidence to support improvement in climacteric symptoms and the meta-analysis of a 178 studies on soy products was inconsistent. Nevertheless, other studies disagree. Mammographic density is not affected by soy or phytoestrogen products and recent in vitro work shows only a weakly proliferative effect of soy isoflavone on breast cancer cells and evidence that soy isoflavone blocks the proliferative effect of estradiol on these cells. There are no studies looking at clinical outcome measures for cardiovascular disease but a number of studies looking at biochemical markers including arterial wall stiffness and apolipo protein B. Recent studies have also looked at the effects of red clover isoflavone on mood and depression, using specific depression rating scales. Finally, it is important to note that herbal medicinal products should not be used without caution. Some may produce quite marked side-effects in high doses and others can interact with pre-existing medication. A strategy for which patients are suitable for herbal medicinal products is reviewed.  相似文献

Homosexuality has become a divisive issue in many religions and congregations. Like many other fundamentalist denominations, Jehovah's Witnesses condemns homosexual acts, thoughts, and feelings. Consequently, gay and lesbian Witnesses experience not just stigmatization and conflict between their sexual and religious identities in the social world, but also a nearly impossible task in their inner world. This inner task adds a new facet to our understanding of stigma (Goffman, 1963). This study explores the written narratives of a subset of gay and lesbian former Jehovah's Witnesses who were able to comprehend, negotiate, and, in most cases, resolve their multifaceted stigmas and conflicts through struggle, self-determination, and eventually connecting with networks of peers who faced or are facing similar stigmas. This research contributes to other work on the intersection of religion, family, and homosexuality; in particular, the findings have implications for the study of other strict fundamentalist religions.  相似文献
