从人力资本与经济的发展关系看贵州教育

经济的跨越式发展与人力资本的发展相关,成功的经济追赶是人力资本追赶的结果,且人力资本的积累与教育的发展密切相关,教育的快速发展取决于教育制度的创新,贵州教育的发展特别是高等教育的发展必须加大投入,解放思想,用新的思路实现贵州教育的发展目标。     

企业资本结构与产品市场战略

直到20世纪80年代,企业资本结构对产品市场竞争的影响才引起经济学家的广泛关注.对于这一问题的研究,存在着两种截然不同的理论结论:一种观点认为企业债务水平的提高会使其在产品市场竞争中更为强硬,增强其竞争力;另一种观点则恰好相反.事实上,企业的融资决策具有两种不同的间接效应:代理效应和策略效应.企业的融资决策在其代理效应和策略效应的平衡点达到最优.企业的融资决策与其产品市场策略之间的关系依赖于代理问题的性质、不确定性的来源及产品市场的特征等因素,企业的最优资本结构应该随这些因素的变化而变化.     

信息资源会计:企业信息化效益计量和评价的新思路

全面系统地对信息资源投入和收益的计量和评价一直是推动企业信息化工作的难点 ,解决该问题的一个新思路是 :信息资源会计。信息资源是广义的概念 ,即包括信息内容和信息技术、设施、人员等全部支持要素在内。企业信息化必然要投入信息资源 ,结果会引起组织资源配置的变化和重新组合 ,以货币价值形式计量、分析、评价这一过程就是信息资源会计的主要职能。

Reconsidering the Evolution of Nonlinguistic Communication: The Case of Laughter

Nonlinguistic communication is typically proposed to convey representational messages, implying that particular signals are associated with specific signaler emotions, intentions, or external referents. However, common signals produced by both nonhuman primates and humans may not exhibit such specificity, with human laughter for example showing significant diversity in both acoustic form and production context. We therefore outline an alternative to the representational approach, arguing that laughter and other nonlinguistic vocalizations are used to influence the affective states of listeners, thereby also affecting their behavior. In the case of laughter, we propose a primary function of accentuating or inducing positive affect in the perceiver in order to promote a more favorable stance toward the laugher. Two simple strategies are identified, namely producing laughter with acoustic features that have an immediate impact on listener arousal, and pairing these sounds with positive affect in the listener to create learned affective responses. Both depend on factors like the listener's current emotional state and past interactions with the vocalizer, with laughers predicted to adjust their sounds accordingly. This approach is used to explain findings from two experimental studies that examined the use of laughter in same-sex and different-sex dyads composed of either friends or strangers, and may be applicable to other forms of nonlinguistic communication.     

Human Salmonellosis: Estimation of Dose-Illness from Outbreak Data

The quantification of the relationship between the amount of microbial organisms ingested and a specific outcome such as infection, illness, or mortality is a key aspect of quantitative risk assessment. A main problem in determining such dose-response models is the availability of appropriate data. Human feeding trials have been criticized because only young healthy volunteers are selected to participate and low doses, as often occurring in real life, are typically not considered. Epidemiological outbreak data are considered to be more valuable, but are more subject to data uncertainty. In this article, we model the dose-illness relationship based on data of 20 Salmonella outbreaks, as discussed by the World Health Organization. In particular, we model the dose-illness relationship using generalized linear mixed models and fractional polynomials of dose. The fractional polynomial models are modified to satisfy the properties of different types of dose-illness models as proposed by Teunis et al . Within these models, differences in host susceptibility (susceptible versus normal population) are modeled as fixed effects whereas differences in serovar type and food matrix are modeled as random effects. In addition, two bootstrap procedures are presented. A first procedure accounts for stochastic variability whereas a second procedure accounts for both stochastic variability and data uncertainty. The analyses indicate that the susceptible population has a higher probability of illness at low dose levels when the combination pathogen-food matrix is extremely virulent and at high dose levels when the combination is less virulent. Furthermore, the analyses suggest that immunity exists in the normal population but not in the susceptible population.
