天然气场站维护与管理

天然气场站作为储存与输送天然气的重要场所,其运行与安全管理直接关系到人民群众的生命财产安全,尤其在天然气需求量与供给量逐年递增的形势下,天然气场站的维护与管理工作也面临严峻考验。因此,场站管理人员应当及时查找出场站运行过程中存在的安全风险隐患,并制订一套切实可行的场站设备设施维护与管理方案,进而将安全事故的发生概率降到最低点。文章将紧紧围绕天然气场站的安全风险要素,以及采取维护与管理措施予以全面阐述。     

基于证据推理的家电企业自主创新能力评价模型

根据行业特征提出了针对我国家电企业开展自主创新能力评价的指标体系。家电企业自主创新能力的评价过程中,存在部分定量指标数据获取困难,定性指标评判主观性强等问题,故应用证据推理理论构建评估模型,实现了定性、定量指标的合理测度与集成。最后通过对某家电企业创新能力评价的实证分析,验证了模型的有效性。     

公路沥青路面病害分析及养护

沥青砼路面由于表层平整性好、耐磨性强、振动低与防水性较佳等优势,从而在公路项目施工建设中得到了普遍运用。而受限于自然环境与外部荷载的干扰,沥青路面容易发生裂缝等各种病害,使其使用性能受到了较大影响。为了让公路沥青路面使用年限得以延长,有关检测部门应当详细了解其病害的形成原因,采取有效的检测与预防制度,加强养护工作,以此尽量减轻病害的形成,确保交通通行的安全性。     

How to maintain sustainable consumer behaviours: A systematic review and future research agenda

Maintaining sustainable consumer behaviours is necessary for both mitigating environmental problems and the success of sustainable businesses. However, to date, the focus is mainly on the motivation-adoption link (i.e., how to motivate sustainable consumer behaviours) rather than the adoption-continuance link (i.e., how to maintain those behaviours). This study addresses the link between sustainability adoption and continuance, through a structured literature review. Specifically, this study synthesizes what is (and is not) known about the post-adoption (continuance) stage of the sustainable consumer journey, by reviewing and integrating the results of 87 articles. This review has three key outcomes. First, it elaborates on the importance and distinction of the continuance stage, which is predicted by a set of different and ‘evolving’ factors, compared with motivation and initial adoption. Second, the key components of the continuance stage are identified and grouped under (I) post-adoption cognitive perceptions, (II) emotional outcomes, and (III) subsequent behavioural patterns of (dis)continuance, spillover, advocacy, loyalty and habit formation. Third, this study introduces the concept of sustainable consumer behaviour continuity and discusses theoretical relationships in a conceptual framework. Finally, this review identifies knowledge gaps and provides research directions as well as implications for theory and practice.     

延迟退休、生育政策调整与中国经济增长

政府在放松生育政策的同时，配合退休政策的调整具有重要的现实意义。通过构建延迟退休和生育调整的理论模型发现：从劳动力增量看，延迟退休能够产生即期效应，而生育调整具有滞后效应，且两者导致的劳动力增量差距呈现先扩大后缩小的特点，节点在2031年；从社会总负担看，在实行延迟退休后，总抚养比迅速下降到一个低水平位置；从总产出看，同时实施延迟退休和放松生育政策，经济中潜在的福利损失最小；从产出增速看，放开生育的同时配合延迟退休，经济增速下降最慢；从人均产出看，放开生育的同时最好配合延迟退休，否则人均收入提升的效果不如政策不变时效果。     

Anchoring the mission: A framework for understanding mission maintenance in professional service firms

Mission maintenance in professional service firms must balance the commercial and professional logics and prevent mission drift. Based on a case study of ‘auditing in action’ in a German professional service firm we argue that mission maintenance results from interactions between the practice and field level. We find that anchors on the field level target individuals’ discretionary choices by balancing competing demands from the commercial and professional logics on the practice level. Therefore, we identify anchoring as a central cross-level mechanism for maintaining the balance between routinizing for professional quality and ‘flexibilizing’ for efficiency on the practice level. With these findings we make two contributions to the literature: an analysis of how the field level can contribute to maintaining organisations’ missions in fields that have competing logics, and the identification of anchoring as a central mechanism to balance competing demands with the expectations of referent audiences on the field level.

A multiple criteria sorting method for supporting the maintenance management of medical ventilators: The case of Hospital da Luz Lisboa

Medical equipment is characterized by a constant flow of innovations, which is transforming the delivery of healthcare. This creates the need for healthcare organizations to incorporate methodologies to support the maintenance management of these equipment. Within this context, Luz Saúde, the holding company of one of the largest healthcare groups in Portugal, intends to complement the medical equipment maintenance management program of the biggest hospital in its network, Hospital da Luz Lisboa. To this aim, we develop a decision aiding tool for assessing the maintenance condition of medical ventilators and recommend a plan of action. For that, we apply a multicriteria decision aiding methodology, utilizing the Electre Tri-nC method. In interaction with the decision makers, we construct a model using twelve criteria for assigning ventilators to one of the five ordered categories representing the current condition (excellent, very good, good, adequate, and poor). Most of the medical ventilators in the analysis were considered in adequate or good maintenance conditions, which was consistent with the decision makers’ expectations. A detailed analysis of the results evidenced the robustness of the model. This study constitutes the first step toward the use of multicriteria methodologies for supporting decision processes in Hospital da Luz Lisboa.     

Skilled maintenance trades under lean manufacturing: Evidence from the car industry

This article explores how skilled maintenance trades have fared under lean automotive manufacturing, a cohort of workers relatively neglected in the literature. Historically, such trades possessed a distinct ‘craft consciousness’ derived from apprenticed-acquired skill, autonomy in job execution, strict job boundaries and relative occupational status and prestige. The article assesses how lean has impacted this craft tradition over time, drawing on a case study of one UK car plant to assess its trajectory across three decades. Four different skilled cohorts—electrical, mechanical, control engineers and die maintenance fitters—are examined to gauge respective trends in skill, autonomy, demarcation and status. While the study finds variation in experiences across different trades, the general trend points to a deterioration in work conditions on all four benchmarks of assessment. The article concludes by inferring implications for the future trajectory of skilled trades considering recent accounts provided in Industry 4.0 narratives.
