电子书用户使用意愿影响模型构建与实证     

杨方铭  张志强 《图书情报工作》2020,64(9):85-94

[目的/意义] 探究用户使用电子书意愿的影响因素，以有助于电子书产业走出缓慢的发展困境。[方法/过程] 以UTAUT2、使用满足理论为基础，从需求满足和外部情景因素两个层面构建影响因素模型，并将需求满足细化为内容需求、社交互动需求和休闲娱乐需求3个测量变量。采用问卷调查方法收集有效样本1 013份，使用AMOS21软件对模型进行验证。[结果/结论] 研究发现，需求满足、阅读习惯、价格价值、社会影响对使用意愿有正向影响作用，而激励措施对使用意愿有负向影响作用，努力期望对使用意愿的影响不显著，并依据研究结果提出促进电子书产业发展的建议。  相似文献   

Association between psychosocial stressors with emotional and behavioral problems among children of low-income addicted families living in Brazil     

《Child abuse & neglect》2019

BackgroundChildren exposed to substance use in their families are vulnerable to multiple risk factors in their development and at increased risk for emotional and behavioral problems. The aims of the study were as follows 1) estimate the prevalence of emotional and behavioral problems among children aged 6–11 years old, living with addicted family members in a low-income urban community of São Paulo, Southeastern Brazil; 2) evaluate the children’s exposure to family psychosocial stressors and substance use; and 3) investigate the factors related to the increased risk of emotional and behavioral problems and substance use.MethodsA cross-sectional study was conducted among 101 children aged 6–11 years old (M = 9.16 years, SD = 1.61). The instruments used were a sociodemographic questionnaire, the Child Behavior Checklist (CBCL) and the Psychosocial Stress Factors (PSF).ResultsHigh prevalence of problems was found for this sample: the CBCL showed 26.7% of clinical scores for Internalizing Problems, 40.6% for Externalizing Problems, and 40.6% for Total Problems. Exposure to family psychosocial stressors was also high, including severe disease (33%), physical aggression (28.9%), death (27.8%), psychiatric hospitalization (16.7%), suicide attempts (15.5%), and suicide (9.3%). Exposure to these family stressors was associated with an increase of two to four times in the prevalence of internalizing and externalizing problems.ConclusionsChildren exposed to substance abusers have more mental health problems than general population, even when compared to peers living in similar low-income areas. This is a group that should be target of a selective preventive intervention.  相似文献   

Making it real: The benefits of workplace learning in upper-secondary vocational education and training courses     

《Economics of Education Review》2014

In OECD countries, ‘real world’ upper-secondary vocational education and training (VET) programs are used to engage less academically oriented youth in learning, while helping to prepare them for post-school work and/or further education. In general terms, VET programs with high employer involvement, such as apprenticeship schemes, are considered to be superior to classroom-based VET programs that are typically found in many English-speaking countries. In this study, we examine outcomes from a potential ‘third way’: classroom-based VET with a short-term structured workplace learning component. Using propensity score matching and PISA data linked to information from the Longitudinal Survey of Australian Youth, we find this model is associated with higher school completion rates and better employment transitions.  相似文献   

Social media and students’ behavioral intentions to enroll in postgraduate studies in Kenya: a moderated mediation model of brand personality and attitude     

Gabriel Simiyu  Ronald Bonuke  Joyce Komen 《Journal of Marketing for HIGHER EDUCATION》2020,30(1):66-86

ABSTRACT

Using cross-sectional data from 504 students from four Kenyan universities, this study evaluates the indirect effect of brand personality on the relationship between social media and students’ behavioral intentions to enroll in postgraduate studies. Additionally, the study examines the moderating effect of attitude on the relationship between social media and brand personality, social media and students’ behavioral intentions, brand personality and students’ behavioral intentions. Finally, it investigates the moderating effect of attitude on the indirect process of brand personality on the relationship between social media and students’ behavioral intentions. The study is guided by the Theory of Planned Behavior, Technology Acceptance Model and Self Congruity Theory. Process Macro is used to analyze data. Results indicate that social media significantly predicts students’ behavioral intentions and this relationship is partially mediated by brand personality. Besides, attitude moderates the relationship between social media and students’ behavioral intentions and also the relationship between brand personality and students’ behavioral intentions. Finally, attitude has a conditional effect on the indirect relationship between social media and student’s behavioral intentions via brand personality and this effect is much stronger with a higher level of attitude. These findings contribute new knowledge to literature and theory.  相似文献   

社会经济学的三大流派:一个简要述评     

王军 《湖州职业技术学院学报》2014,(4):45-49

社会经济学从萌芽发展繁荣,期间形成了众多流派,影响较大的主要有三大流派:天主教社会经济学、人本主义社会经济学、奥地利派社会经济学。天主教社会经济学强调受到天主教教义的指导,人本主义社会经济学则是以人为中心来开始研究,奥地利派社会经济学强调经济社会是一个整体。在发展过程中,奥地利派社会经济学到了21世纪30年代发展演变成了"奥地利经济学派";人本主义社会经济学则另立山头,出现了发展专门的人本主义经济学的趋势;天主教社会经济学则不断淡化宗教色彩,扩大开放,借鉴吸收其他学科的最新理论成果,大有融合、包容其他社会经济学的倾向。现阶段,当代社会经济学还在快速发展中,其发展走向还有待观察。  相似文献

联盟伙伴视角下产学研联盟稳定性提升路径——理论框架与实证分析     

曹霞  于娟 《科学学研究》2016,33(10):1522-1531

适宜的联盟伙伴对产学研联盟的稳定发展至关重要。本文从联盟伙伴角度出发,运用话语分析和理论假设分析构建出提升产学研联盟稳定性路径的理论框架,并通过投影寻踪和多重中介模型对上述理论框架中的提升联盟稳定性的作用路径进行了实证分析,结果表明:联盟伙伴特征越明显越有利于产学研联盟的稳定发展;同时,联盟伙伴还可以通过行为整合和界面管理间接影响产学研联盟的稳定性,行为整合和界面管理起部分中介作用,且二者的中介效应存在差异,行为整合的中介效应要比界面管理的大。  相似文献
