注塑制品残余应力的分析与计算

注塑制品已广泛应用于生活、生产等各个方面，注塑制品的残余应力是决定制品形状、表面质量、使用性能的主要因素。注塑制品的残余应力有两个来源：一个是流动残余应力。一个是热残余应力。结合熔体在注塑过程中的粘弹性变化特点。分析了注塑制品残余应力的产生原因和影响因素，给出了残余应力的计算方法。研究残余应力的产生机理对改善成型加工工艺条件、提高产品质量、降低废品率具有重要意义。     

“网运分离”模式下我国铁路运输业路运的竞争

为铁路运输业引入竞争以提高其效率,是一切改革方案的最终目的。“网运分离”模式为此提供了可能。虽然从理论上分析,“网运分离”后铁路运输业存在多种竞争形式,但真正有效的是线路运营权的竞争和与其它运输方式间的竞争两种。从有效竞争理论和可竞争市场理论分析,在我国铁路运输业引入竞争,需要政府、企业、社会多方面的努力。     

我国西部发展药用植物种植的机遇与对策

加入WTO后 ,中医药具有竞争优势 ;西部大开发的实施、野生药用资源的短缺和较高的市场价位 ,为西部地区发展药用植物种植业带来了难得的机遇 ,但经营方式落后、种植户抵御市场风险能力差、后续开发不力等因素制约着西部药用植物种植业的发展。因此 ,必须因地制宜 ,注重生态效益 ;采用产业化模式延长产业链 ;加大开发和推广力度 ;利用中医药的文化内涵发展旅游业。     

Banach空间中线性流形的单值度量投影算子部分

刘晶和王玉文于2001年引入并研究了Banach空间中线性流形的单值度量投影算子部分，但他们是在空间X和Y均自反、严格凸的强几何假定下来进行讨论的，这极不利于应用．我们在X和Y均是一般Banach空间的弱假定下，讨论并研究了Banach空间中线性流形的单值度量投影算子部分，并给出了该算子部分的结构的刻划．这为将比Lee S.J.与Nashed M.Z.所引进并研究的Hilbert空间集值线性映射包含的最小二乘解推广到Banach空间奠定了理论基础，所得的本质地推广了刘晶与王玉文的结果。     

组织学习主体:哲学与嵌入性视角的分析

组织学习主体的定义是开展组织学习研究的重要逻辑起点,但目前关于组织学习主体的考察尚缺乏一致认识,这已经制约了组织学习研究的深入开展.本文基于哲学视角,依据组织学习的过程对组织学习主体进行了分析,基于社会学嵌入性理论对组织学习主体的社会-个人特征进行了分析.     

Restructuring Flexibility: Case Studies of Part‐Time Female Workers in Six Workplaces

The article is based on six workplace case studies within a local economy and investigates the reasons behind the different utilization of part‐time workers within these workplaces. The research examines the content and nature of part‐time work in these organizations and the experiences of the part‐time workforce. The findings suggest that we need to distinguish between three types of part‐time workers; core, peak and ancillary. It is argued that such distinctions capture the variegated utilization of part‐time workers and contribute to the debate concerning the integration or marginalization of part‐time staff within workplaces. Furthermore, workplace cultures are an important arena for contextualizing these discussions. It is contended that the different uses of part‐time workers can be explained by different sectoral and organizational contexts but that the nature of part‐time work is also influenced by existing social relations within the workplace, notably with respect to gender, class and age.     

Challenging the Rhetoric of Choice in Maternal Labour‐Force Participation: Preferred Versus Contracted Work Hours

The notion of choice in maternal labour‐force participation (LFP) is a contentious one, with assertions that LFP is a direct result of either personal inclinations, such as employment commitment or external factors, such as historically available opportunities. This article suggests an alternative framework for understanding and testing choice in LFP using preferred versus contracted work hours. It explores these constructs quantitatively in a group of working mothers (N = 275) with dependent children and investigates qualitatively the underlying reasons for discrepant preferred versus contracted work hours in a sub‐sample of these women with under‐school‐aged children (N = 20). The results show that nearly two‐thirds of women working full time would prefer to work part time and the major reasons for not acting on their preferences is because of the nature of the job and the lack of career opportunities available for part‐time employees.     

Consent as Resistance,Resistance as Consent: Re‐Reading Part‐Time Professionals’ Acceptance of Their Marginal Positions

The part‐time employee has traditionally occupied a marginal position in organizations. The recent increase in the numbers of part‐time professionals, however, has been seen as offering potential for the status of the part‐time employee to improve. Evidence to date suggests that this improvement has not taken place and that the part‐time professional is also marginalized. Interestingly, research suggests that part‐time professionals may not experience their subordinate positions as problematic, often believing that the drawbacks of reduced hours working are a legitimate consequence of their ‘choice’ to work part‐time. Such ‘choices’ are frequently attributed to part‐timers’ prioritization of non‐work activities. In this article, using a Foucauldian approach to identity, we argue that choices need to be understood as both situated in time and space and constituted through discourse. Using these ideas we provide a re‐reading of part‐timers’ consent to their marginalization, arguing that their responses to their positions at work can also be understood as resistance to some of the dominant norms of professionalism. We set out the conditions that might be implicated in translating subjective resistance into more material actions.
