探索矿业行政合同制度的走向

矿山企业依行政特许对矿产开发、生态恢复、矿山安全等方面作出书面的承诺,应属矿业行政合同.矿业行政合同,是当事人不同方向意思表示的一致,是公共利益最优化和私人利益最大化的最大公约数,是市场和政府双向失灵时政府利用市场的政策工具,是政府的强制又充分利用了市场激励和相对人的认同,是促进政府转变职能并有利于依法行政和民主行政的杠杆.矿业行政合同的订立实行特许权、参与保留、担保和公众参与等制度,其履行须引入强制制度;司法救济则实行双向模式的主动选择原则,行政相对人主动提起则适用行政诉讼,行政主体提起则适用民事诉讼,这种"双向模式"弥补了混合模式和单一模式的不足.

Family Provisions at the Workplace and Their Relationship to Absenteeism,Retention, and Productivity of Workers: Timely Evidence from Prior Data

Using data from the Australian Workplace Industrial Relations Survey, this study provides timely evidence on the effects of on‐site child care at the workplace and employer‐provided family leave on worker absenteeism, turnover, and productivity. The study found that workplaces with on‐site child care compared with workplaces with no on‐site child care had lower rates of absenteeism and higher ratings for worker productivity. Workplaces that had a family leave policy also had lower rates of absenteeism than workplaces that had no such policy in place. Analyses also suggest that workplace characteristics, such as presence of a human‐resources manager or union representative, are associated with higher worker productivity. Firm size, mission, and shift work were other predictors of worker performance. The findings argue strongly for an extensive, new workplace survey that can elucidate how parents today manage to abide by new workplace agreements while still handling the demands of family life.     

高校后勤服务型小实体的探索

高校后勤社会化改革初期成立的后勤集团总公司或后勤服务总公司等后勤大实体,运行过程存在着种种弊端。打破后勤大实体,组建服务型小实体,解散原后勤队伍,引进社会力量,共同参与学校的后勤服务,是实现高校后勤社会化的有效途径。     

Robust scale estimation in the error-components model using the empirical characteristic function

Robust estimators of the scale parameters in the error-components model are described. The new estimators are based on the empirical characteristic functions of appropriate sets of residuals and are affine equivariant, consistent and asymptotically normal. The robustness of the new estimators is investigated via influence-function calculations. The results of Monte Carlo experiments and an example based on real data illustrate the usefulness of the estimators.

Intelligent Procedures for Intra‐Day Updating of Call Center Agent Schedules

For nearly all call centers, agent schedules are typically created several days or weeks before the time that agents report to work. After schedules are created, call center resource managers receive additional information that can affect forecasted workload and resource availability. In particular, there is significant evidence, both among practitioners and in the research literature, suggesting that actual call arrival volumes early in a scheduling period (typically an individual day or week) can provide valuable information about the call arrival pattern later in the same scheduling period. In this paper, we develop a flexible and powerful heuristic framework for managers to make intra‐day resource adjustment decisions that take into account updated call forecasts, updated agent requirements, existing agent schedules, agents' schedule flexibility, and associated incremental labor costs. We demonstrate the value of this methodology in managing the trade‐off between labor costs and service levels to best meet variable rates of demand for service, using data from an actual call center.     

Mass Customization in the Automotive Industry: Comparing Interdealer Trading and Reconfiguration Flexibilities in Order Fulfillment

Mass customization has been viewed as desirable but difficult to achieve in the volume automotive sector. Here we consider flexibility in automotive order fulfillment systems to enhance the ability to satisfy customers with their desired vehicle variants within acceptable delivery lead times. Two types of flexibility are compared in a Virtual‐Build‐to‐Order system—reconfiguration in the planning pipeline and interdealer trading. A representative simulation model is used to investigate the impact of the two types of flexibility across a wide spectrum of product variety levels. The impacts on major stakeholders in the system—the producer, dealers, and customers—are considered. The study shows that both types of flexibilities can bring significant benefits in terms of reductions in lead time and inventory holding. The level of product variety strongly influences the observed effects—an important finding in the mass customization context. Upstream reconfiguration flexibility brings greater benefits than downstream trading flexibility. Reconfiguration tends to dominate trading as a fulfillment mechanism when both are in operation. The findings have implications for the design and management of automotive order fulfillment systems in improving their ability to offer mass customization. The study has relevance for companies in other sectors with high levels of variety that seek to combine efficiency, speed, and flexibility in order fulfillment.
