气浮-水解酸化-接触氧化-活性炭吸附工艺处理针织行业废水

在毛衣加工生产过程中其废水排放存在水量不稳定、水中污染物浓度较高的问题,采用“气浮-水解酸化-接触氧化-活性炭吸附”组合工艺处理后, COD、硫化物、色度的去除率分别达到96．85％、97．3％、94％,经处理后出水水质可以达到《纺织染整工业水污染物排放标准》（ GB4287-2012）中的直接排放标准,该工艺可用于类似工业废水的治理。     

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.     

中国企业对外直接投资的内外动力源研究

联合国贸发会议(UNCTAD)发布的<2006年世界投资报告>指出:来自发展中国家和转型期经济体的外国直接投资(FDI)开始蓬勃兴起.2006年,发展中国家跨国公司对外直接投资额达到了创纪录的1200亿美元.其中,中国在吸收外资保持世界领先的同时,自身的对外直接投资也呈现出快速增长的态势,中国跨国公司的崛起已经引起全球注目.文章在分析中国对外直接投资概况的基础上.以全球视野对中国企业对外直接投资的内外动力源进行了研究,希望以此促进中国企业的对外直接投资.
