优先股在金融危机中的应用及其启示

对2008年美国金融危机中优先股发挥的重要救助作用尤其是对其在对金融机构的救助中发挥的作用进行深入分析，研究优先股在危机时刻对金融机构的应用价值。通过梳理总结美国政府在危机后采取的一系列重大举措，分析研究优先股在其中应用比例、途径等，发现优先股是危机时刻使用频率最高和范围最广的金融工具。提出优先股在危机时刻能快速实现注资等救助目的，稳定金融市场，因此，中国有必要建立救助时期优先股制度，且应根据危机时刻和非危机时刻同时构建金融机构的优先股制度。

A meta-analytic examination of the potential correlates and consequences of workload

Over the last four decades, occupational stress researchers have given considerable attention to the potential correlates and consequences of workload. In the current study, we use meta-analysis (overall k = 336) to quantitatively review the workload literature. In analyses of hypothesized correlates, we found that social support was negatively associated (ρ = ?.20 for supervisor support; ρ = –.11 for co-worker support) and that trait negative affectivity (ρ = .22), role ambiguity (ρ = .28), role conflict (ρ = .44) and work-family conflict (ρ = .44 for work-to-family conflict; ρ = .20 for family-to-work conflict) were each positively associated with workload. Analyses examining hypothesized outcome variables suggest that workload is negatively associated with several indices of psychological and physical well-being (ρs were generally in the –.20s and –.30s), and affective organizational commitment (ρ = –.11), and is positively associated with turnover intention (ρ = .16) and absenteeism (ρ = .07).     

罗马法视角的文化资源的产权归属

21世纪是文化经济时代.文化资源是文化产业、文化事业发展的前提和基础.文化资源在承载着一个国家、民族的物质成果和精神追求的同时,也以交易的方式实现文化资源的财富价值.文化资源需要有效开发,更待合理保护.罗马法中可交易物与不可交易物的类型划分,公有物、共用物和共有物、私有物的类型标准,为文化资源的产权归属、产权权利人利益的实现提供了学理根据.这对确认文化资源的产权归属,维护文化资源权利主体的相关权益,明确文化资源的产权流向和交易规则,具有重要作用.     

基于变结构协整的股指期货跨期套利

随着中国股指期货市场成交量的扩大和流动性的加强,合约间价差的变化更加复杂和多变。为了改进传统跨期套利策略的效果,使用允许结构突变的变结构协整模型对价差进行建模,设计了一套完整的程序化交易策略,并选取IF1311,IF1312,IF1401和IF1402的真实高频交易价格数据进行实证研究。结果表明：中国股指期货合约价格存在大量突变现象,变结构协整模型策略在3对合约间的交易表现相较于传统模型策略,能捕捉到更多交易机会、更高的收益率和更大的夏普比率。     

中国完善应急预案的关键问题--对七大关系的考量

预案是应急准备的一项重要内容,但在应急实践中,中国预案的针对性、实用性与可操作性不足,缺少实效性,因此,需完善应急预案。完善应急预案的关键问题在于正确处理应急预案管理中的七大关系,即静态与动态、目标与能力、预测与现实、简单与复杂、分工与协调、详细与灵活、集权与分权的关系。     

Variables acceptance reliability sampling plan for repairable items

Traditionally, acceptance reliability sampling plans have been developed for non-repairable items. However, the functions required for items become more and more complex and, accordingly, the items are composed of several components and tend to be repairable. In this paper, we consider variables acceptance reliability sampling plan for repairable items. We develop a variables acceptance sampling plan based on the failure and repair data observed during the testing period. It is shown that the developed sampling plan improves the reliability characteristic of the population and that the lifetimes of items before and after the reliability sampling test are stochastically ordered.     

建设海峡西岸社会主义新农村的价值选择

建设社会主义新农村,本质是要缩小城乡差距,使农村在加速工业化、城市化的过程中能够与城市共同协调发展,使农民与城市居民一样享受等值不同质的现代生活。以等值不同质为取向增进农民福祉,是海峡西岸社会主义新农村建设的出发点和落脚点。建设海峡西岸社会主义新农村,要树立大资源观,以增量资源为杠杆激活存量资源,构建平等、互动、共福的新型城乡关系。     

当前农地制度对农民收入影响的分析与思考

农地制度下的家庭经营形式极大地提高了农民收入,但是,家庭经营形式下的小生产方式与大市场之间的矛盾越来越明显,对农民收入的进一步提高产生了制约。现行农地制度存在土地产权制度既很模糊又不完整,产权关系紊乱;土地承包经营权流转市场化程度低;土地的承包经营制度制约了农业经营规模的扩大和农业生产效率的提高等问题。探索以明晰土地所有权为核心的土地制度创新,才能进一步提高农业生产效率,提高农民收入。     

Sizing Inventory When Lead Time and Demand are Correlated

Determining appropriate inventory levels has been a subject of interest for both researchers and practitioners. Standard practice is to treat lead time demand as a random sum of random numbers and rely on established probability theory to calculate both reorder point and safety stock levels. A key assumption in these calculations, however, is that lead time and demand are not correlated. In this paper, we first explore situations where this assumption is untrue and then develop equations to determine the reorder point and the safety stock when lead time and demand are correlated. More specifically, we (1) derive formulas for the average and variance of the demand in a lead time, which can then be used to calculate the reorder point and the safety stock, (2) apply these formulas to two distributions for which there is a closed‐form solution: normal and Poisson, and (3) examine the effect of correlation on safety stock requirements under the normal distribution.
