论现代企业品牌管理

美国经济的衰退和全球高新技术市场的增长滞缓 ,给寻求跨地域发展的企业投下了重重的阴影 ,以往成功的经验已不足以借鉴。中国企业目前所具有的竞争力只能保持 3- 5年的时间。加入WTO后 ,中国企业品牌的寿命周期将会大大缩短。面对国际、国内环境的巨大变化 ,企业品牌的核心竞争力必须进行重新评价和创意。     

西方国家高校组织的自主权及其启示

西方国家高校组织的自主权是通过大学内部立法、决策领导、组织协调、咨询等办学活动来实现的。大学自治组织系统主要由董事会 (校务会 )、校长、评议会等组成。校长由董事会 (校务会 )选举或产生 ,代表其行使学校决策及日常事务管理。大学自治组织一般拥有组织教学、筹集经费、开展学术研究、人事使用等权力 ,而这些权力的行使一方面要受到大学内部各种权力系统、管理层以及利益集团的制约 ,同时还要受到来自大学外部的各种专门组织和社会团体的监督

Bayesian validation assessment of multivariate computational models

Multivariate model validation is a complex decision-making problem involving comparison of multiple correlated quantities, based upon the available information and prior knowledge. This paper presents a Bayesian risk-based decision method for validation assessment of multivariate predictive models under uncertainty. A generalized likelihood ratio is derived as a quantitative validation metric based on Bayes’ theorem and Gaussian distribution assumption of errors between validation data and model prediction. The multivariate model is then assessed based on the comparison of the likelihood ratio with a Bayesian decision threshold, a function of the decision costs and prior of each hypothesis. The probability density function of the likelihood ratio is constructed using the statistics of multiple response quantities and Monte Carlo simulation. The proposed methodology is implemented in the validation of a transient heat conduction model, using a multivariate data set from experiments. The Bayesian methodology provides a quantitative approach to facilitate rational decisions in multivariate model assessment under uncertainty.

Optimal sampling for repeated binary measurements

The authors consider the optimal design of sampling schedules for binary sequence data. They propose an approach which allows a variety of goals to be reflected in the utility function by including deterministic sampling cost, a term related to prediction, and if relevant, a term related to learning about a treatment effect To this end, they use a nonparametric probability model relying on a minimal number of assumptions. They show how their assumption of partial exchangeability for the binary sequence of data allows the sampling distribution to be written as a mixture of homogeneous Markov chains of order k. The implementation follows the approach of Quintana & Müller (2004), which uses a Dirichlet process prior for the mixture.     

Couple Attitudes and Agreement Regarding Pregnancy Wantedness in the Philippines

We compare husbands' and wives' views of the wantedness of their most recent pregnancy in the Philippines, a country where relatively high levels of unintended fertility persist. This research is an extension of earlier work that looked separately at individual men's and women's responses. We analyze survey data for 369 couples and find that those most at risk of experiencing a pregnancy that neither spouse wanted tended to be higher parity couples, those who were more fatalistic, those who were practicing Catholics who attended religious services frequently, and those among whom the husband was the sole breadwinner. Higher parity women and older women were also more apt to experience a pregnancy that was wanted by only 1 spouse. Women who had difficulty discussing sexual matters with their husbands were more likely than other women to have a pregnancy that their husbands wanted but they did not.
