基于交易成本理论的工程合同类型与交易成本探讨

工程合同类型选择问题在工程实践中研究较为广泛,然而对于该问题的更深层次的探讨,特别是在经济学领域的探索却相对较少。在经济学理论影响社会显著发展的当今,应用经济学理论探讨社会经济问题是十分必要的。论文以新制度经济学中交易成本理论研究成果为基础,通过对交易成本的重新理解,分析其与不同合同类型问的联系,得到具有一定指导性的结论,有助于进一步研究和探索。     

接触氧化-二氧化氯消毒工艺处理医院污水

医院污水排放量不均衡,污水中含有大量的病原性微生物及有毒、有害的物理、化学污染物。采用接触氧化-二氧化氯消毒处理工艺后,污水可以达到广东省地方标准《水污染物排放限值》(DB44/26-2001)中二类污染物第二时段一级排放标准。文章介绍了接触氧化-二氧化氯消毒处理工艺的工艺流程、主要设施与设备、处理效果及处理成本,总结了工程特点。     

鲁地拉水电站地下厂房岩壁吊车梁设计

鲁地拉水电站工程地下厂房吊车梁采用岩壁吊车梁结构。设计时采用《地下厂房岩壁吊车梁设计规范(Q/CHECC 003-2008)》推荐方法对梁体受拉锚杆的截面积、锚固长度以及梁体的抗滑稳定等进行了详细的计算。此外还应用ANSYS程序,采用二维、三维非线性有限单元法,精细模拟了围岩、梁体、锚杆以及岩壁吊车梁与岩体的接触面,对岩壁吊车梁的受力特性进行了系统的计算分析。数值仿真分析结果表明采用接触面单元、锚杆单元,充分考虑了梁体与围岩之间的张开、接触、摩擦以及受拉锚杆与围岩的相互作用,较好地反映了岩壁吊车梁在各种工况下的工作性态及支护机理,对其他工程的岩壁吊车梁的稳定性分析、支护设计有较好的借鉴和指导作用。     

Job quality in the customer contact centre: conceptual foundation and scale development

To develop a comprehensive framework of dimensions of job quality in a customer contact centre (CCC), this study adopts the employee's perspective and proposes 12 dimensions. Previous studies suggest conceptualizations of the dimensions of job quality, but have failed to address the specific dimensions that need to be taken into account in a CCC setting. With its multiple dimensions, the proposed job quality scale achieves high internal validity, reliability and generalizability in the CCC setting. Yet the increasing role of such centres for service delivery makes them and their employees critical to customers' quality perceptions, and the findings of this study offer managers clear guidelines adjusted to the CCC environment.     

Off-shoring in the contact centre industry and employment in the North West of England

The significance of contact centre employment has recently been the subject of renewed debate in regional policy-making of late, driven by media comment on the threat of off-shoring. Despite these concerns, empirical research on the scale of such activities in regions is limited. This article reviews available data on contact centre employment in the sub-regions of North West England. The evidence appears to show continued growth in the number of contact centres and employment totals. The concluding section reconsiders the significance of contact centres for Regional Economic Strategies that focus on developing high value-added activities.

Ethnic homophily perceptions as an emergent IHRM challenge: evidence from firms operating in Sri Lanka during the ethnic conflict

Ethnic conflict is a defining characteristic of the post-Cold War era and is prevalent particularly in emerging economies, areas of increasing interest to multinational enterprises. Yet little is known about the international human resource management challenges arising from such societal context. Utilizing social identity theory, we propose that ethnic homophily perceptions in the workplace – an employee's assessment that colleagues prefer working with ethnically similar others – is a reflection of the societal context and can be detrimental to the organization if not managed appropriately. We investigate whether contact theory offers insights to manage such perceptions. Drawing on a sample of 550 managers in Sri Lanka during a period of protracted ethnic conflict, we found that employee sensitivity to ethnic conflict in the societal context is positively related to ethnic homophily perceptions in the workplace, and that both ethnic diversity in workgroups and quality of work relationships serve to reduce perceptions of ethnic homophily.
