浅析共线运营在我国城轨交通中的合理运用

共线运营可分为支线形式和非支线形式两种类型。作为一种城市轨道交通的运营模式,共线运营可以在有限的路线长度上大幅增加运营总里程,提高城轨输送效率。在规划运营方案,确定采用哪种运营模式时,应考虑城市轨道建设的实际和可以具备的条件。广州地铁4、5、8号线和北京地铁2、13号线的共线运营线路可作相应的改进。     

Social capital and human resource management in international joint ventures in Vietnam: a perspective from a transitional economy

This study highlights the importance of social capital in international joint ventures (IJVs), and examines human resource practices as a factor shaping such social capital. Comprehensive measures of social capital are developed and tested, which extend prior work on ‘bonding’ and ‘bridging’ social capital. We also link social capital with its anticipated antecedents and consequences. The study's findings are based on data collected from 164 IJVs located in Vietnam. IJV performance was predicted by training and by the level of trust and cooperation between foreign and local personnel. Training (including acquisition of management skills, technology, and cross-cultural understanding) also was predictive of the measures of social capital. A key practical implication arising from this study is that the return on investment from training of joint venture personnel can stem not only from the transfer of technical and management skills needed for developing competitive advantage, but also from the positive impact on social capital, which further contributes to venture success. The establishment of written objectives and plans for the venture, as well as the IJV's level of control regarding its own HR functions also was found to be related to some components of social capital. The findings of this study reinforce the call to build on the contributions of local personnel in joint ventures, and in Vietnam in particular.     

城市共同配送中心选址研究——基于生态位和混合整数规划法视角

在分析影响选址生态适宜性因素的基础上,引入生态位适宜度模型进行第一次筛选,旨在揭示资源现状对城市可持续发展的适宜性程度。此外,采用混合整数规划模型对剩余备选方案进行二次筛选,并以Z市为例,计算各备选点与理想点的距离远近,确定最终共同配送中心方案。实证结果表明该模型能较好地处理城市生态环境与共同配送中心选址问题,以期为其他城市共同配送选址提供一定借鉴。建议政府着眼城市未来发展,加强共同配送中心的基础设施建设,合理布局,提高资源利用率,促进整个共同配送中心协调运作。     

Understanding the alliance data

A considerable body of research utilizes large alliance databases (e.g., SDC, MERIT‐CATI, CORE, RECAP, and BIOSCAN) to study interorganizational relationships. Understanding the strengths and limitations of these databases is crucial for informing database selection and research design. In this study I conduct an analysis of five prominent alliance databases. Focusing on technology alliances (those formed for the purposes of joint research or cross‐technology transfer), I examine the databases' consistency of coverage and completeness, and assess whether different databases yield the same patterns in sectoral composition, temporal trends, and geographic patterns in alliance activity. I also replicate three previously published alliance studies to assess the impact of data limitations on research outcomes. The results suggest that the databases only report a fraction of formally announced alliances, which could have detrimental consequences for some types of research. However, the databases exhibit strong symmetries in patterns of sectoral composition, alliance activity over time, and geographic participation. Furthermore, the replications of previous studies yielded results that were highly similar to those obtained in the original studies. This study thus provides some reassurance that even though the databases only capture a sample of alliance activity, they may yield reliable results for many—if not all—research purposes. This information should help researchers make better‐informed decisions about their choice of database and research design. Copyright © 2008 John Wiley & Sons, Ltd.     

Joint Production and the Structure of Technology: A Generalization

In this paper, we have a peek inside the black box of technology in an attempt to get a better understanding of the concept of joint production. We introduce the notion of input and output subtechnologies; these are then used as building blocks to define various types of production processes, either joint or nonjoint. Thus, in the 2×2 case, we are able to identify up to 36 different production structures, some of which are well known, but most of which are new. These are all described in the primal quantity space as well as in the dual price space. Comparative statics results for the 2×2 joint production process are derived.     

The impact of manager's animosity and ethnocentrism on multinational enterprise (MNE) international entry‐mode decision

For MNEs, entry‐mode decision is undeniably critical. While the literature has identified several determinants of foreign entry‐mode choice, few have examined the impact of manager's animosity and ethnocentrism. This article is an attempt to fill this gap by examining the independent effect of manager animosity and ethnocentrism as well as the moderating effect of cultural intelligence on entry mode. Data were collected through surveys targeting upper‐level managers in the U.S., U.K., and Germany to examine how animosity and ethnocentrism would shape their decision to enter Iran, a host market largely perceived negatively in the West. Multivariate multiple regression was used to test the hypothesized effects and to capture the multidimensional aspect of entry modes. We found that, in general, manager's animosity and ethnocentrism do negatively affect the choice of an entry mode and that cultural intelligence has the potential to neutralize that negative effect.     

Partner nationality, market-focus and IJV performance: A contingent approach

This study examines how Taiwanese firms engaging in various types of international joint ventures (IJVs) have performed in China, and how different types of market-focus affect IJVs’ performance. Based on the IJV classification scheme suggested by [Makino S., & Beamish P. W. (1998). Performance and survival of joint ventures with non-conventional ownership structures. Journal of International Business Studies, 29(4): 797–818], this study outlines and examines three categories of IJVs, according to partner nationality: Taiwan-Taiwan (T-T) JVs, Taiwan-Local (T-L) (China) JVs, and Taiwan-Foreign (T-F) (third-country) JVs. We propose two hypotheses, with associated sub-hypotheses, to examine the major effects of partner nationality on performance, as well as the moderating effects of local market-focus on the relationship between partner nationality and performance. Through the analysis of 236 Taiwanese JVs in China, we find that (1) T-L JVs perform better than T-T JVs and T-F JVs; (2) T-L JVs focusing on the local market do not perform better than those focusing on foreign markets; and (3) T-F JVs focusing on foreign markets perform better than those focusing on the local market.

A Typology of Partial-Order: The Case of Drug Use in Israel

A frequent variety of typology is that which results when a given population is classified simultaneously by several criteria, the categories of each criterion being ordered in a sense common to all the criteria. Such simultaneous orderings automatically define a partial order typology.The empirical problem is to ascertain the dimensionality and the substantive meaning of the partial order. This is illustrated here by characterization of the Jewish population of Israel by the frequencies of use of a variety of drugs. The data analysis approach adopted is that of Partial Order Structuple (Scalogram) Analysis (POSA). The particular computer program used is POSAC (POSA with Base Coordinates).The analysis revealed that it is possible to portray the distinct profiles (structuples) of the respondents according to drug use in a two-dimensional space, with a substantive regularity relating both to legal (pain relievers) and illegal drugs (marijuana, methadon). This space also serves as a basis for discriminant analysis for age as an external background variable.
