新加坡土地综合利用效率探讨

新加坡经济发达、人口密集、土地狭小。、但有限的土地并没有成为新加坡经济社会发展的制约。相反,通过借鉴世界城市规划发展的成功经验和自身的创新土地管理,新加坡在土地空间利用上展现了其面对住房、交通、环境、水资源利用等城市发展共同挑战问题时独特的解决方法。长期稳定的综合规划、短期局部的灵活应变和土地效益的综合考量成为新加坡土地政策的三大特征。新加坡在土地管理中对土地使用效率和社会公平兼顾的政策理念与效果,对中国快速城市化进程中的土地管理有非常有益的借鉴。

IGLOO: An integrated framework for sustainable return to work in workers with common mental disorders

ABSTRACT

Current research on return to work (RTW) for employees with common mental disorders suffers from two limitations. First, research mostly focuses on the influence of resources during the absence period ignoring the resources which may facilitate sustainable RTW, i.e. employees continuing to work and thrive at work post-return. Second, research tends to view the work and non-work domains separately and fails to consider the interaction of resources at the individual, group, leader and organisational levels, once back at work. In the present position paper, we present an integrated framework and a preliminary definition of sustainable RTW. Based on current occupational health psychology theory and existing research on RTW, we develop ten propositions for the resources in and outside work, which may promote sustainable RTW. In addition to the individual, group, leader, and organisational levels, we also argue for the importance of the overarching context, i.e. the societal context and the culture and legislation that may promote sustainable RTW. Our framework raises new questions that need to be addressed to enhance our understanding of how key stakeholders can support employees with common mental health disorders staying and thriving at work.     

End-to-end process management: implications for theory and practice

The term ‘end-to-end’ process management is now commonplace in the language and practice of operations. Managers are encouraged to migrate from functional process management to end-to-end process management to realise a range of performance improvements. However, these improvements are often elusive; the specific challenges associated with such a migration are under-researched. This paper uses a cross-sector study to identify the challenges of end-to-end process management and to generate practical managerial guidance. Three areas are identified that demand particular managerial attention: the need to move beyond process mapping, the role of IT in process management and maintaining the process infrastructure as a strategic asset. More significantly, the findings highlight the need for greater conceptual clarity regarding the end-to-end concept itself. The existing literature suggests that scope is the primary differentiator of the end-to-end process – the requirement to manage an extended boundary from customer order through to customer fulfilment. However, this research suggests that the end-to-end concept is more complex, comprising of three core constructs with seven dimensions: scope (boundary conditions, sequence/flow and controls); scale (resources and input/output transformation) and complexity (interrelationships and orientation). End-to-end process management involves much more than an extended boundary. It requires a systemic perspective and clarity regarding controls and transforming resources.     

An integrated modelling approach for raw material management in a steel mill

An integrated modelling approach combining optimisation models with simulation is proposed for coordinated raw material management at steel works throughout the whole supply chain management process. The integrated model is composed of three components: ship scheduling, yard operation simulation and material blending models. The ship scheduling model determines which brands, how much and when they should be arrived, and the problem is modelled as mixed integer linear programming. The simulation model is used to simulate the whole processes from ships’ arrivals to the retrieval of the materials through the berthing and unloading the raw materials. Finally, the raw material blending model is developed for determining the brand and quantity of raw materials to be used. The proposed integrated modelling approach for raw material management has been successfully implemented and applied at steelwork to provide shipping schedules and predict future inventory levels at stock yards. By coordinating all the activities throughout the entire raw material supply chain management process, this article proposes an integrated approach to the problem and suggests a guideline by the appropriate simplification. The quantitative nature of the optimisation model and simulation facilitates an assessment of the risk factors in the supply chain, leading to an evaluation of a wide variety of scenarios and the development of multiple contingency plans. Further research is expected to supplement the ship scheduling models with heuristics for the idiosyncratic constraints of maritime transportation.     

基于工序异质性的关键链项目缓冲监控

通过关键链项目缓冲监控可以防止缓冲在项目执行阶段被浪费,并保证项目的工期,有效的监控方法有利于提升项目的整体绩效。为了克服统一缓冲监控方法的不足,在保证项目工期的基础上,本文考虑成本因素对项目的影响,提出了一种基于工序成本和工期敏感度的差别动态缓冲监控模型。该模型考虑工序异质性将工序划分为成本敏感型工序和工期敏感型工序,根据工序的综合感知效用进行缓冲监控分配,并结合敏感度对不同类型的工序设置不同的监控基准点和纠偏措施。仿真结果表明,差别监控相对于统一的监控模式有利于实现项目工期和成本的双优化,验证了本文方法的有效性。     

The role of CEO emotional stability and team heterogeneity in shaping the top management team affective tone and firm performance relationship

In this paper, we aim to bridge the micro-macro divide by addressing continued calls from strategic leadership and affect researchers to examine the black box to consider how CEO characteristics relate to top management team (TMT) affective experiences, and, in turn firm outcomes. We further consider the role of one key contextual factor in this relationship: TMT heterogeneity. We predict that CEO personality, specifically, emotional stability, is positively associated with TMT affective tone. Moreover, we posit that the relationship between TMT affective tone and firm performance depends on TMT task-related heterogeneity, such that positive affective tone benefits firm performance in heterogeneous TMTs, whereas negative affective tone benefits firm performance in homogeneous TMTs. Using a novel methodology that measures key psychological aspects of the CEO and TMT, we examined 50 TMTs from publicly-traded companies to test our predictions. Our findings offer theoretical contributions to the strategic leadership, affect and diversity literatures as well as managerial applications for CEO selection and management and managing diversity in upper echelons.

预应力混凝土脊骨梁剪力滞效应研究

脊骨梁的悬臂特别长,作为梁的一部分,翼板将参与梁的纵向弯曲,其横向剪力滞效应非常显著;同时悬臂板将板上的荷载横向传递给脊梁时产生横向弯曲,即还存在纵向剪力滞效应问题,为了明确脊骨梁整体和局部力学行为特征,以及翼板在横向弯曲时的纵向有效分布宽度,通过组合有限元方法,建立脊骨梁的三维实体单元模型,考虑预应力和各种加载方式,分析预应力混凝土脊骨梁纵向、横向剪力滞效应,为混凝土脊骨梁的设计提供参考。     

中国流通领域改革开放30年回顾

中国流通领域的改革开放是建立社会主义市场经济体制的重要内容。改革开放之前,中国流通领域长期存在高度集中而又封闭分割的特征,国内与国外市场、内贸与外贸相互隔绝,存在两个管理体制和两种政策环境。经过30年的改革开放,中国流通领域的体制环境已经面貌一新,开放型现代流通体制框架已经初步建立,与WTO接轨的商务管理体制已见雏形,商贸服务业的产业延伸促进了体制创新。改革的主要经验是,以对外开放为先导,以开放促改革;改革遵循先易后难、边破边立、逐步完善的渐进路径;突破传统商品流通领域框架,建立了容纳更多服务业的新商务体制。改革经验的经济学含义是,选择出口导向开放战略作为改革突破口具有必然性：商品与服务流通的市场结构与人力资本存在内在联系;扩大非物质产品流通是体制创新的重要基础。
