Robustness of a Class of Partial Diallel Cross Designs to the Unavailability of a Complete Block of Observations

Complete and partial diallel cross designs are examined as to their construction and robustness against the loss of a block of observations. A simple generalized inverse is found for the information matrix of the line effects, which allows evaluation of expressions for the variances of the line-effect differences with and without the missing block. A-efficiencies, based on average variances of the elementary contrasts of the line-effects, suggest that these designs are fairly robust. The loss of efficiency is generally less than 10%, but it is shown that specific comparisons might suffer a loss of efficiency of as much as 40%.     

TERRITORIAL RESTRICTIONS IN FRANCHISE CONTRACTS

Efficient contracts set incentives through the assignment of rights and profit shares., Although efficient contracts have been used to explain the nature of the firm, the use of contractual rights in specific business contracts is relatively unexplored. We analyze contractual rights in franchise systems, in particular the right to add franchisees. An exclusive territory assigned to an initial franchisee is not an immutable guarantee, but rather a starting point for subsequent renegotiation in the franchise relationship. Exclusivity is therefore profitable when franchisee efforts are critical to the venture. A sample of franchise contracts reveals evidence consistent with the model's prediction.     

Low dose risk estimation via simultaneous statistical inferences

Summary.  The paper develops and studies simultaneous confidence bounds that are useful for making low dose inferences in quantitative risk analysis. Application is intended for risk assessment studies where human, animal or ecological data are used to set safe low dose levels of a toxic agent, but where study information is limited to high dose levels of the agent. Methods are derived for estimating simultaneous, one-sided, upper confidence limits on risk for end points measured on a continuous scale. From the simultaneous confidence bounds, lower confidence limits on the dose that is associated with a particular risk (often referred to as a bench-mark dose ) are calculated. An important feature of the simultaneous construction is that any inferences that are based on inverting the simultaneous confidence bounds apply automatically to inverse bounds on the bench-mark dose.

新形势下高校思想政治教育过程的行为分析

思想政治教育的过程是客体作用于主体，并通过主体不断内化的过程，其效果与教育者和被教育者的行为动机密切相关。本文以高校思想政治工作的教育者和被教育者为研究对象，通过分析他们在实施和接受思想教育过程中的行为动机，指出了当前思想政治教育工作在制度安排上存在的问题和不足，并初步提出了加强和改进思想政治工作的具体措施。

论资本质量与财务目标

从传统财务目标的缺陷在于忽视资本质量的分析入手 ,论述了资本质量是资本的内在规定性 ,是资本社会属性的总和与资本经济属性的质量方面 ;将资本质量引入财务目标是由资本的本质和财务的本质、资本质量与资本数量之间的关系、时代特征和国家财务所决定的 ,资本质量最优化与资本数量最大化是财务目标的必然选择 ;提出了资本质量考核指标体系。
