论公正及其与自由、平等的关系

尽管学术界对自由、平等和公正问题有许多研究和阐释,但较少将自由、平等与公正问题联系起来从总体上进行考察和研究,以致关于自由、平等和公正及其关系问题成了人们最说不清、道不明的问题。本文试图立足于当代人类社会现实及其走向,着重从与自由、平等相互关联的视角研究公正问题,力求纲要性地对公正及其与自由、平等之间的关系提供一些阐释和见解,最终论证这样一种基本观点:现代公正是一种综合性的价值要求,它要求社会自由和平等,也要求对自由和平等可能导致的社会问题给予适当解决。     

美国房地产投资证券化的组织模式及其借鉴

在我国实行房地产投资证券化既有市场需求，也有客观需要。美国是世界上最早实行不动产证券化的国家。美国不动产证券化的主要形式有“不动产投资信托”和“有限合伙“两种，并各具特点。我国应借鉴其合理因素，为加快不动产发展步伐提供制度支持。     

Looking for contagion in currency futures markets

This article tests whether there are pure contagion effects in both conditional means and volatilities among British pound, Canadian dollar, Deutsche mark, and Swiss franc futures markets during the 1992 ERM crisis. A conditional version of international capital asset pricing model (ICAPM) in the absence of purchasing power parity (PPP) is used to control for economic fundamentals. The empirical results indicate that overall there are no mean spillovers among those futures markets, but they are detected during the crisis period. That is, past return shocks originating in any one of the four markets have no impact on the other three markets during the entire sample period, suggesting that these markets are weak‐form efficient. However, this weak‐form market efficiency fails to hold during the market turmoil, especially for British pound and Swiss franc, and the sources of contagion‐in‐mean effects are mainly due to the return shocks originating in three European currency futures markets. As for the contagion‐in‐volatility, it is detected for British pound only because its conditional volatility is influenced by the negative volatility shocks from Canadian dollar, Deutsche mark, and Swiss franc, with Deutsche mark playing the dominant role in generating these shocks.

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.     

Conditioning as disintegration

Conditional probability distributions seem to have a bad reputation when it comes to rigorous treatment of conditioning. Technical arguments are published as manipulations of Radon–Nikodym derivatives, although we all secretly perform heuristic calculations using elementary definitions of conditional probabilities. In print, measurability and averaging properties substitute for intuitive ideas about random variables behaving like constants given particular conditioning information.
One way to engage in rigorous, guilt-free manipulation of conditional distributions is to treat them as disintegrating measures—families of probability measures concentrating on the level sets of a conditioning statistic. In this paper we present a little theory and a range of examples—from EM algorithms and the Neyman factorization, through Bayes theory and marginalization paradoxes—to suggest that disintegrations have both intuitive appeal and the rigor needed for many problems in mathematical statistics.     

上海服务业发展水平的国内与国际比较

本文首先比较了上海与国内18个副省级及以上城市服务业总体发展情况，将上海服务业各行业增加值及服务业内部构成与北京、天津、重庆、广州和深圳5个国内经济发展水平较高的城市进行了比较，采用“区位熵”的方法衡量了上海服务业各行业的比较优势。其次，将上海服务业发展水平与若干国际大都市进行比较，得出上海服务业仍处于较低的发展水平，尚未进入以知识型、生产型等高级服务业为主导的发展时期，大力发展现代服务业是上海当前的现实选择的结论。     

网络营销创新定位、运行模型及案例分析

网络营销的创新性质包括创新程度和创新效益两个方面。创新程度反映网络营销创新的影响力度,是过程性指标;创新效益反映网络营销的经济效应,是结果性指标。将创新度和效益度垂直相交构成一个二维平面,并将其分别划分为高低两个级别段,可形成四个定位模块,即触网型创新、网络实验型创新、网络营销专家和运营网络型创新。一般情况下,企业网络营销创新往往从触网型创新出发。进而上升到运营网络型创新阶段,但在网络营销实践中,某些创新运动并不是严格地起于触网型创新,而止于运营网络模型,更有逆向运行的情况存在。

AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.
