The present study investigates the relationship between CEO’s information literacy and innovation in small and medium-sized enterprises (SMEs). Even if information literacy’s business value has been recognized in recent literature, its impact on organizational innovation, a critical and strongly information intensive process, has never been studied before. Structural equation modeling based analysis of data collected from 184 company CEOs in Finland revealed that CEOs’ information literacy has a positive impact on the development of exploratory and exploitative innovations in SMEs. Additionally, opportunity recognition mediates the relationship between information literacy and innovation. Overall, the influence of information literacy is slightly stronger on exploitation than exploration. Nevertheless, the mutual positive effect suggests that information literacy enhances innovation ambidexterity in organizations. Based on these findings, we discuss theoretical and practical implications as well as future research opportunities in workplace information literacy research.  相似文献

Political polarization remains perhaps the “greatest barrier” to effective COVID-19 pandemic mitigation measures in the United States. Social media has been implicated in fueling this polarization. In this paper, we uncover the network of COVID-19 related news sources shared to 30 politically biased and 2 neutral subcommunities on Reddit. We find, using exponential random graph modeling, that news sources associated with highly toxic – “rude, disrespectful” – content are more likely to be shared across political subreddits. We also find homophily according to toxicity levels in the network of online news sources. Our findings suggest that news sources associated with high toxicity are rewarded with prominent positions in the resultant network. The toxicity in COVID-19 discussions may fuel political polarization by denigrating ideological opponents and politicizing responses to the COVID-19 pandemic, all to the detriment of mitigation measures. Public health practitioners should monitor toxicity in public online discussions to familiarize themselves with emerging political arguments that threaten adherence to public health crises management. We also recommend, based on our findings, that social media platforms algorithmically promote neutral and scientific news sources to reduce toxic discussion in subcommunities and encourage compliance with public health recommendations in the fight against COVID-19.  相似文献

Educational effectiveness research has provided evidence about the importance of teacher beliefs and attitudes for teaching and learning. This study builds on the concept of academic optimism, which combines 3 aspects of a teacher’s professional creed: self-efficacy, trust, and academic emphasis. The study explores the functioning of the collective and individual measures of academic optimism in the Czech environment and studies its impact on students’ outcomes. The analyses are based on pilot data from 39 schools, 325 teachers, and 1,316 Grade 9 students and on the data from the Czech Longitudinal Study in Education (CLoSE), covering 163 schools, 1,469 teachers, and 4,798 students. The individual measure was selected for further studies based on 2-level confirmatory factor analysis. Two-level structural equation modelling showed a significant impact of a school’s academic optimism on students’ achievement even after controlling for prior achievement and socioeconomic status at both the student and the school level.  相似文献

张坊岩溶地貌是中国北方岩溶类型的典型代表。分析张坊地区的地层展布与构造变形,探讨地层-构造演化与岩溶发育的关系。研究区主要出露近水平的中上元古界碳酸盐岩夹细碎屑岩和硅质岩,主要经历印支期(或更早期)伸展状态下的固态流变变形、燕山期的逆冲-褶皱变形和房山岩体期后的伸展变形等多期次构造演化,造就了研究区复杂的褶皱、断裂、构造裂隙和岩溶地貌特征。大型溶洞的发育主要与中上元古界的岩性-地层展布、中生代的逆冲断裂和新生代的伸展断裂等地质作用有关。在多阶段沉积-变形等地质作用控制下,发育了中元古代、古生代、中生代和新生代4期古岩溶,形成构造抬升侵蚀溶蚀、构造反转溶蚀冲蚀和多次抬升溶蚀侵蚀等3种主要溶洞发育类型。  相似文献

As we can see in recent studies on mobile banking, there is an increasing number of papers addressing this new technology. Mobile banking contributes to the quality of life of people living in both developed countries, and also in emerging economies. In this context, we develop this paper in order to compare the determinants of mobile banking use between respondents from two countries with different levels of development: Brazil and the United States. Our theoretical model includes six variables as determinant factors of mobile banking use. In order to analyze path coefficients and test the six hypotheses, we employed a structural equation model. We also employed a quantitative test (multi-group analysis) to analyze the difference of path coefficients between the models of the two countries. The main results indicate similarities among the perceptions of the respondents that participated in the survey, but differences in coefficient magnitude.  相似文献

我国海外投资企业日益关注东道国创造性资产寻求,希望借此实现自主创新能力提升,那么如何获取东道国知识资源成为亟待解决的难题。在外商在华FDI活动中,我国企业往往借助知识和技术溢出效应获取资源和提升技术水平,而在我国向发达国家的OFDI活动中,这一方式则不太适用,我国企业需要更具主动性和针对性的知识获取途径和共享模式,而由海外子公司向母公司的针对性逆向知识转移则更能有效满足我国企业的特定资源需求,并有助于我国企业实现自主创新能力提升。本文试图从逆向知识转移方式出发,探究其作为我国企业获取东道国创造性资产路径的可行性,同时深入研究其影响因素和内在作用机制。为揭示我国跨国公司母公司微观因素对逆向知识转移的推动作用,本文围绕母公司战略因素和子公司逆向知识转移评价设计问卷,以我国海外投资企业问卷调研数据为基础,采用中介效应检验和结构方程模型探究了母公司国际化动因,子公司影响力对逆向知识转移的影响作用。实证结果证实以上两类因素对逆向转移的应用和创新效果具有促进作用,其中国际化动因体现为对海外创造性资产寻求的重视程度,子公司影响力从母公司对子公司的战略、文化和股权控制三方面实现对逆向知识转移的显著影响,而创造性资产的影响作用还通过转移意愿的中介效应体现,子公司影响力则借由渠道建设的中介作用实现。最后综合实证分析和华为案例佐证的结论,本文构建基于母公司战略和子公司影响力、转移意愿和渠道建设的逆向知识转移作用机制,为我国企业实践提供对策建议:(1)鼓励我国海外投资企业关注创造性资产寻求,尤其关注东道国技术、管理、市场和文化知识。(2)鼓励创造性资产寻求动因,提高对子公司的战略、文化和股权控制水平,提升子公司绩效对母公司的影响力,借以促进子公司逆向转移意愿;同时借由母公司控制程度提升,激励子公司完善渠道建设,实现基于编码和人员的双轨道知识转移系统,从而促进逆向转移效果。(3)增强全资子公司或控股合资等高控制度的海外市场进入模式实现更高水平的股权控制,同时通过对子公司的统一战略规划和资源支持加强其战略控制水平,通过构建更具内部凝聚力和控制力的强文化体系来加强对子公司的文化影响。(4)不仅关注逆向知识转移后的知识应用过程,更关注知识再创新和自主创新过程,实现后发国家的技术追赶。  相似文献

Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.  相似文献
