“三维需求空间”中的柱形产业链——对产业链生成机制的阐释

对产业链的研究是当前产业经济学的前沿问题。现在对产业链的研究大多是从供给和生产的角度展开而且很不专业化、独立化。因此,在产业链生成机制的理论解释上存在着先天不足。从需求出发,以供给和需求联动为基础,以生产需求和消费需求的对接为核心,初步建立一个“三维需求空间”的柱形产业链模型,力图从一个新的角度来阐释产业链的生成机制。     

Optimal split‐plot orthogonal arrays

It is well known that many industrial experiments have split‐plot structures. Compared to completely randomised experiments, split‐plot designs are more economical and thus have received much attention among researchers. Much work has been done for two‐level split‐plot designs. In this article, we consider split‐plot designs with factors of three, more than three, or mixed levels and with both qualitative and quantitative factors. We show that if two designs with both qualitative and quantitative factors are geometrically isomorphic, then their generalised wordlength patterns are identical. Three design scenarios are considered for optimal designs. The corresponding wordlength patterns are defined and the minimum aberration mixed‐level split‐plot designs having 18 and 36 runs are tabulated.     

Partial Comparative Messages in Competition

Partial comparative messages comprise a mixture of comparative and non-comparative claims. This study demonstrates how the extent to which non-comparative (NC), partial comparative (PC) and complete comparative (CC) messages influence consumer preference depends on the comparisons (i.e. NC, PC or CC) made by the messages promoting the two competing brands. A 3 (brand A used NC, PC or CC message) × 3 (brand B used NC, PC or CC message) design was used. Two studies (n=284, 283, respectively) show that participants preferred (1) the first brand they saw when both brands were promoted by NC messages, (2) neither brand when both brands were promoted by messages containing comparative claims, (3) the brand promoted by a PC message when the other brand was promoted by an NC message, and (4) the brand promoted by an NC message when the other brand was promoted by a CC message.

三亚回族多语现象回访及分析

“回访”是文化人类学针对同一调查点进行长期跟踪调查的重要方法之一.本文主要就海南三亚回族多语现象进行回访调查,并同1984年的调查结果进行对比分析,找出当地回族掌握多语情况的变化及原因和特点.     

Trade-off between quoted lead time and price

In a make-to-order environment, lead time and price can play a crucial role in determining the financial success of a firm. Their importance increases when demand is sensitive to the quoted lead time and price. A model is presented which uses the quoted lead time and price as a mechanism to determine the optimal demand level. The relationships between the model parameters and their impacts on the firm's profit is also analysed. In addition, the effect of the number of job requests, and the mean processing time are examined. Based on the results presented in this paper, there is clear indication that the firm's profit is sensitive to the inventory holding rate, and that the inventory holding cost component is redundant in the presence of a tardiness cost component.     

A Likelihood-Based Approximation to the Cumulative Distribution Function of the Noncentral t Distribution

Optimal designs for estimating the parameters and also the optimum factor combinations in multiresponse experiments have been considered by various authors. However, till date, in mixture experiments optimum designs have been studied only in the single response case. In this article, attempt has been made to investigate optimum designs for estimating optimum mixing proportions in a multiresponse mixture experiment.     

Family Control and Stock Market Reactions to Innovation Announcements

Although family firms are common around the world, studies on family‐controlled business are limited. Prior studies mainly focused on the influences of family ownership on overall firm performance, and the results were mixed. In this study we attempted to explore the impacts of family ownership on innovation by examining the association of family control and stock market reactions to innovation announcements. We found that firms with greater family control experienced significantly more negative stock market reactions to innovation announcements. The results further indicated that divergence of cash flow and voting rights was strongly and negatively correlated with announcement‐period abnormal returns. In addition, the findings suggested a significantly positive moderating effect of institutional ownership. The conclusions were robust under various measures of family control, and remained valid after controlling other influential factors for stock market reactions to innovation announcements.
