农民工对失业保险的潜在需求研究——基于河北省的社会调查

在市场经济和社会化大生产的背景下,农民工面临失业风险大、生活保障弱、再就业难等问题,导致农民工群体对失业保险制度存在潜在需求。现行失业保险制度由于给付条件过于严格、保障水平低以及就业促进功能缺位等原因,不能与农民工对失业保险制度的潜在需求匹配。应以农民工实际工资为缴费基数,采用灵活的缴费率机制,并将缴费金额、缴费时间与支付水平相挂钩,为农民工建立既有别于正规就业,又能与正规就业的失业保险制度接轨的弹性失业保险制度。     

弹性学制下的高校教学管理

弹性学制的实行使原有的教学管理模式发生了根本改变,必须有相应的教学管理办法与之配套。本文对弹性学制中教学计划的制定、学籍处理、选课管理、考试管理等提出了自己的观点和具体的操作办法,并对弹性学制中存在的问题提出建议。     

Management gender composition and the gender pay gap: Evidence from British panel data

Women continue to earn less than their male counterparts globally. Scholars and feminist activists have suggested a partial explanation for this gender gap in earnings could be women's limited access to power structures at the workplace. Using the linked employer–employee data of the Workplace Employment Relations Study 2004–2011, this article asks what happens to the gender gap in earnings among non‐managerial employees when the share of women in management at the workplace increases. The findings, based on workplace‐fixed time‐fixed effects regression models, suggest that workplace‐level increases in the share of women in management are associated with decreases of the non‐managerial gender gap in earnings. This effect appears to be largely unrelated to changes in equality and diversity policies, family‐friendly arrangements and support for carers at the workplace.

Lowest Cost May Not Lower Total Cost: Using “Spackling” to Smooth Mass‐Customized Production

Consider a manufacturer who mass customizes variants of a product in make‐to‐order fashion, and also produces standard variants as make‐to‐stock. A traditional manufacturing strategy would be to employ two separate manufacturing facilities: a flexible plant for mass‐customized items and an efficient plant for standard items. We contrast this traditional focus strategy with an alternative that better utilizes capacity by combining production of mass‐customized and standard items in one of two alternate spackling strategies: (1) a pure‐spackling strategy, where the manufacturer produces everything in a (single) flexible plant, first manufacturing custom products as demanded each period, and then filling in the production schedule with make‐to‐stock output of standard products; or (2) a layered‐spackling strategy, which uses an efficient plant to make a portion of its standard items and a separate flexible plant where it spackles. We identify the optimal production strategy considering the tradeoff between the cost premium for flexible (versus efficient) production capacity and the opportunity costs of idle capacity. Spackling amortizes fixed costs of capacity more effectively and thus can increase profits from mass customization vis‐à‐vis a focus strategy, even with higher cost production for the standard goods. We illustrate our framework with data from a messenger bag manufacturer.     

A comparative analysis of due date based job sequencing rules in a flow shop with multiple processors

The literature on job scheduling recognizes the importance of due date performance criteria such as mean tardiness and maximum tardiness. A number of studies test a large number of sequencing rules for these criteria in job shop and flow shop settings. The object of this present research is to examine the performance of some well-known priority rules in a flow shop with multiple processors. This study investigates the performance of ten priority rules in terms of mean and maximum tardiness. It examines the effects of problem characteristics, such as number of jobs, number of machines stages and number of parallel processors at each stage, and the performance of priority rules using regression analysis. The findings of the study suggest that the primary determinants of tardiness-based criteria are problem characteristics. In addition, both the regression analysis and the analysis of variance provide strong evidence of the strategy-effect. Finally, a detailed performance review of examined priority rules for various problem characteristics is presented.

中等职业学校试行弹性学制与学分制的探索

中等职业学校试行弹性学制与学分制的必然性,是机遇、问题、转型的共同要求。可选择、自主培养、兼容管理等优越性,尤其是学生的积极态度,已成为中职学校试行弹性学制与学分制的最大可行性。应着眼于必修、限定选修、任意选修的课程体系改革,弹性学分与弹性学制的分层教学与管理、综合能力评价体系的建立。而克服体制滞后,家长、学生、教师未能适应等困难,关键要充分认识学分制的主动学习本质、差异教学方法,有针对性的引导服务,教学互动的高层次管理,并加大现代教育技术应用的力度。

免疫遗传算法在柔性Job-shop调度问题中的应用

借鉴生物免疫机理提出了一种求解柔性Job-shop车间调度问题的免疫遗传算法．仿真结果表明，该算法有效地避免了传统遗传算法中因选择压力过大造成早熟现象的发生，显著地提高了遗传算法（GA）对全局最优解的搜索能力和收敛速度，这将使遗传算法在众多实际的优化问题上具有更广泛的应用前景．
