从福建某奶牛场250头进口荷斯坦牛采血提取牛血液DNA,根据已知牛染色体上CD18编码基因序列383位碱基由A 变为G 而引起牛白细胞粘附缺陷病设计特异性野生型和突变型探针,建立实时荧光定量PC R 检测方法用于牛白细胞粘附缺陷病的基因分型检测。结果检出2头母牛为牛白细胞粘附缺陷病携带者,检出率为0.8%,没有发现患病牛。结果证明本研究建立的实时荧光定量PC R 检测方法是一种敏感性和特异性很高的筛选奶牛牛白细胞粘附缺陷病有害基因的新方法。 相似文献

The prevalent and complicated religiosity inside Chinese consumer makes it interesting but difficult to investigate the relation between their religiosity and consumer behaviour. Based on the marketing and psychology background in the Chinese context, this study explored the relationship between Chinese religiosity and their customer loyalty. Cross‐sectional survey data and statistical methods were used to compare customer loyalty under different levels of religiosity. The results reveal significant and positive differences of customer loyalty among consumers with different extent of religiosity in most product categories. This study puts forward a new perspective for marketers to predict and develop loyal customers, even to promote marketing segmentation and customer value. 相似文献

本文研究国资委招标选聘审计师政策的实施效果。以2000年至2011年政府控股的A股上市公司为样本,研究发现:首先,经国资委通过招标选聘的审计师审计后,公司财务重述的情况显著减少。其次,通过招标选聘审计师能降低审计收费。这表明通过招标选聘审计师总体上能得到"质优价廉"的审计服务。并且中央国资委实施招标选聘审计师的效果好于各级地方国资委。最后,进一步分析发现,中央国资委招标选聘审计师时,所选聘的会计师事务所规模比较大,而地方国资委选聘的审计师则更多是本地小事务所。本文研究表明,限制央企管理层影响审计师的招标选聘审计师政策,能够提高审计质量和降低审计费用。 相似文献

When communication quality is trustworthy? Transactive memory systems and the mediating role of trust in software development teams 下载免费PDF全文
Fangcheng Tang 《R&D Management》2015,45(1):41-59
While the importance of communication frequency to transactive memory system (TMS) development has well been established, few studies have been done examining the relationship between communication quality and transactive memory systems in software development teams. This study empirically tests the relationships between communication quality and TMS, and the effect of TMS on team effectiveness. We also examine the mediating effect of trust on the link between communication quality and TMS. By investigating 86 software development teams in China, the results suggest that: (1) communication quality has a positive effect on TMS; (2) the link between communication quality and TMS is mediated by benevolence‐ and competence‐based trust; and (3) TMS has a positive impact on team performance. Theoretical and managerial implications of the study findings are discussed. 相似文献

Vertical specialization (VS) is often measured by the import contents of the exports, using an input–output (I–O) framework. Half of China's exports are processing exports, which largely depend on imported intermediate inputs and tie up upstream as well as downstream trade partners. Thus, one would expect to find strong VS for China. Using the ‘ordinary’ I–O tables, however, this is not the case. Because the production of processing exports is only a small part of total production, the average input structure in the I–O table hides the typical features of processing exports. Using adapted, tripartite I–O tables (for 2002 and 2007) in which the processing exports have been singled out, indeed reveals the expected strong VS in China. 相似文献

This article described the level of hotel participation in environmental management practices (EMPs) in Malaysia. It aimed to identify the level of stakeholder influence on EMP participation and whether EMPs contribute to overall hotel performance. To achieve these objectives, stakeholder theory was selected as the theoretical basis to explicate the proposed hypotheses. The analysis showed that stakeholder influence and the level of participation in EMPs among Malaysian hotels are only at a moderate stage. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
