Pharmaceutical industry plays a strategic role in economy of Iran. Corporate governance, in pharmaceutical companies as the very core of an organization, and the driving force of corporate leadership, plays a significant role in business success and overall productivity of the firms. As yet, the characteristics, factors causing success and failure of core governance in Iranian pharmaceutical industry have remained unsearched. Furthermore, the applicability of western theories and models to the traditional societies such as Iran are largely unknown. This study is an attempt to explore the pattern of board effectiveness and firm performance in Iranian pharmaceutical industry and suggesting an alternative good governance model suitable to apply to less developed countries (LDC) pharmaceutical industry, with emphasis on Iranian context. After An intensive literature review the model suggested by Ingley and Van der Walt (2001) was found to be more comprehensive, practical and suitable for this study. However, after empirical evaluation further development to the model to fit the pharmaceutical industry and the context of LDCs, especially Iran, is suggested. Empirically the paper stands upon a rich database consisting of Tamin Active Pharmaceutical Ingredients Investment Company (TAPIC) and its 11 subsidiary companies which are treated as 11 mini-cases. Data were collected by document analysis, questionnaire and interviews. Since two of the authors have many years experience as managers in the same industrial group, we got access to rich information that normally are not accessible to researchers in less developed countries. The results suggest some improvements to the earlier models and show that the pattern of board effectiveness in Iranian pharmaceutical industry can be influenced by: (1) Internal factors including: (a) board members, the personality and background, (b) board composition, which is influenced by selection criteria, Tribalism, interpersonal relationship and belonging to the same ideological group, (c) board interactions, and (d) power distribution in the board, which is influenced by parenting power in holding companies. All internal factors are directly or indirectly affected by political issues as well as socio-cultural forces. (2) External factors including: (a) industrial complexity and the nature of industry, (b) industrial ethos, (c) legislation, and political forces, (d) economy, which the last two factors are influenced by international environment as well. 展开更多

木质部结构性状是植物适应不同水分条件的基础,也是植物响应环境条件变化的核心属性之一。以西北荒漠区的典型灌木琵琶柴(Reaumuria soongarica)和沙拐枣(Calligonum mongolicum)为研究对象,对其木质部结构和水力功能性状进行对比分析,... 木质部结构性状是植物适应不同水分条件的基础,也是植物响应环境条件变化的核心属性之一。以西北荒漠区的典型灌木琵琶柴(Reaumuria soongarica)和沙拐枣(Calligonum mongolicum)为研究对象,对其木质部结构和水力功能性状进行对比分析,以期了解同一生境中不同物种的差异性或相似性,以及同一物种在不同环境条件下的木质部结构性状的可塑性。结果表明:(1)琵琶柴和沙拐枣的木质部结构性状存在显著差异,沙拐枣平均导管直径、脆弱性指数显著高于琵琶柴,而导管密度、导管分组指数则相反。(2)琵琶柴和沙拐枣的木质部结构性状随气候变化的规律具有差异,随年均降水量和干旱指数的增加,沙拐枣的平均导管直径与导管厚跨比显著下降,而琵琶柴的平均导管直径与导管厚跨比与之无关,仅理论导水率与年均降水量和干旱指数呈显著正相关关系。(3)琵琶柴木质部导水系统存在效率与安全的权衡,而沙拐枣中没有表现出效率和安全的权衡关系。(4)性状网络分析结果表明,琵琶柴和沙拐枣的中心性状均为平均导管直径,平均导管直径的变化介导了性状网络的变化。琵琶柴和沙拐枣的木质部结构性状存在显著差异,相对于沙拐枣,琵琶柴水分利用策略更加保守。 展开更多
