个体信息系统创新性使用行为的影响研究——基于社会影响理论及个人创新特质     

孟椤琰  罗裕梅  张一 《科技管理研究》2019,(10)

信息系统的创新性使用行为能够提高个体工作效率,更好的发挥信息系统的价值,提高企业效益。本文从个体内部和外部影响因素出发,结合个人创新特质和社会影响理论,构建了个体创新特质和社会影响因素对个体创新性使用的研究模型。采用实验的方法,以53个小组(221个个体)为样本进行了实证分析。结果表明,个体创新精神、创新能力及社会影响因素中的主观规范和群体规范均对创新性使用行为产生显著的正向影响,而社会认同感没有表现出显著作用。  相似文献

面向生物合成的代谢工程策略设计          下载免费PDF全文

马红武  陈修来  袁倩倩  刘立明  孙际宾 《中国科学院院刊》2018,33(11):1166-1173

代谢工程研究的主要目的是通过改造菌株代谢网络,高效地合成目的产品。由于细胞代谢网络的复杂性,从数千个代谢反应及其调控回路中找到合适的改造靶点非常困难,往往要经过反复试差才能成功。通过对大规模代谢网络的计算分析,设计出特定生物产品的最优合成途径,可以帮助人们找出合适的代谢工程改造策略,减少改造过程的盲目性,更快更好地得到生物合成菌株。文章重点讨论两个问题:(1)如何设计代谢网络来合成原来不能合成的产品并提高产品得率,介绍了基于代谢网络计算分析的代谢工程设计方法;(2)如何设计菌株实现酶反应的精准调控,介绍了通过设计基因回路动态调控代谢途径流向的动态代谢工程研究新进展。  相似文献   

基于QFD和案例推理的绿色产品设计方案选择研究     

杨东  柴慧敏 《科技管理研究》2018,(16)

应用QFD和案例推理的思想,利用通过QFD方法形成的质量特性及其权重来评价备选的绿色产品设计方案,然后检索出与决策者期望之间相似性最大的绿色产品设计方案。结果表明基于QFD方法可以有效地构建绿色产品设计方案中的指标体系和指标权重。此外案例推理是一种有效的绿色产品设计方案选择方法。可根据实际情况,进行绿色产品设计方案选择,具有一定的实用价值。  相似文献   

The geography of school choice in a city with growing inequality: the case of Vancouver     

Ee-Seul Yoon  Christopher Lubienski  Jin Lee 《教育政策杂志》2018,33(2):279-298

This analysis aims to measure the impact of school choice policy on secondary school students’ enrolment patterns within the social geography of Vancouver, an increasingly polarized global city. The rationale for the study is to examine the impact of ‘education market’ reforms on the socio-economic composition of schools in a Canadian context, where a social welfare commitment to educational equality is being replaced by market-oriented policies and increasing social inequality. Our study is guided by Bourdieu’s theory of site in considering whether growing inequality and polarization of wealth in a city are correlated with the ways families choose schools. We apply a geographical methodology (Geographic Information System) to delineate spatial patterns of choosing schools. Our analysis shows that those who opt out of the under-subscribed schools come from the neighborhoods with relatively higher capital than those who remain in their assigned schools. Also, those who opt into the over-subscribed schools in the affluent areas come from the neighborhoods with above-average levels of capital in Vancouver. Overall, we find that the spatial inequality in school choice generally follows the uneven distribution of capital/wealth across the city. The pattern of student mobility indicates an increasing level of segregation.  相似文献

University surroundings and infrastructures that are accessible and inclusive for all: listening to students with disabilities     

Anabel Moriña  Beatriz Morgado 《Journal of Further & Higher Education》2018,42(1):13-23

The main topic of this article is architectural barriers and infrastructures as identified by university students with disabilities. The data presented is part of a much wider research project, sponsored by Spain’s Ministry of Economy and Competition. A biographical-narrative methodology was used for this study. The results presented have been classified based on one of five barrier types: urban (barriers that are outside the actual university campus), transport (public transportation and personal vehicles), building (obstacles inside university buildings), environmental (those elements within the classroom, including furniture, excessive noise or inadequate temperatures) and communication (these are divided into signposting and barriers when accessing information). Lastly, a variety of questions are considered in the conclusions which indicate that universities still need a certain degree of adaptation and readjustment to really be accessible and inclusive, in keeping with the principles of universal design.  相似文献   

An integrated view of particularized trust in social commerce: An empirical investigation     

《International Journal of Information Management》2019

With the prevalence of social media and social networking, social commerce is becoming increasingly popular in both business and research areas. As in other types of e-commerce context, trust is also indispensable in social commerce. In this study, two types of trust have been discussed. This study represents an initial attempt to provide an integrated view of particularized trust in social commerce, including particularized trust antecedents, trust transfer and trust performance, so as to promote trust formation in social commerce. Using data collected from 614 social commerce users, we demonstrate that trust disposition, quality-assured shared information, familiarity and endorsement by other members are four antecedents of particularized trust. The results also indicate particularized trust can be transferred into system trust, and particularized trust only exerts positive effect on social WOM intention while system trust only exerts positive effect on social shopping intention. Furthermore, we prove perceived similarity can strengthen the relationship between trust disposition and particularized trust as well as the relationship between quality-assured shared information and particularized trust.  相似文献
