Extant research on technology acceptance has devoted considerable attention to the relationship between behavioral intention (BI) and system use (SU) over time. However, the empirical results have been mixed—studies have found BI to both influence and not influence SU. Studies that examined the BI→SU relationship have employed different research models and research designs. Prior research models have examined direct effects on SU, indirect effects on SU through BI, the moderator effects on BI→SU, and the mediating role of BI in BI→SU. Studies have employed different types of respondents, information technologies, geographic regions, voluntariness, and measurement designs. This study proposes that such differences in research models and designs contribute to the mixed results for BI→SU, and reports a meta-analysis of findings reported in 113 prior studies along with a critical review of the BI→SU relationship. While no significant differences were found in the results for the BI→SU relationship across various research design characteristics, this study finds that the measurement of SU has been conflated with future and current or past behavior, direct and indirect effects on SU impact BI→SU, BI is modeled to fully and partially mediate the effects of other variables on SU, and moderators for the BI→SU relationship may be necessary. This study identifies several directions for future research and underlines the need to rethink the link between BI and SU.  相似文献

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献

[目的/意义] 合理使用是维持著作权人个人利益与社会公共利益平衡的重要机制之一,对承担公共文化服务功能的图书馆尤为重要,但实践中图书馆的合理使用条款并未充分发挥利益平衡的作用,有必要对其存在问题及形成原因进行深入分析。[方法/过程] 通过与域外立法相比较,以及司法实践中的案例分析,可看出我国图书馆合理使用的主要问题在于现行法律规定滞后、规则不明晰,导致合理使用适用范围狭窄,还同时受到许可协议、技术措施的挤压。[结果/结论] 为化解图书馆合理使用条款的适用困境,可从增加原则性规定、明确其法律属性为强制性规定、扩大有关条款的适用范围等方面来完善立法。图书馆自身也应加强知识产权管理、提高知识产权素养,严格遵照法律规定以消除侵权隐患。  相似文献

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.  相似文献

Numerous studies have highlighted Intercultural Sensitivity (IS) as a key competence in an increasingly multicultural society. This study examined the extent to which a cohort of first year undergraduate students enrolled on the same Didactics course, and in two different training modalities – Service Learning (SL) and non-Service Learning (non-SL) – developed IS. It was based on a quasi-experimental design of repeated pre-test and post-test measures, comparing the two groups. The sample consisted of 233 Spanish students at higher education institutions, and data was collected using the Intercultural Development Inventory (IDI). The SL group displayed significantly higher levels of IS in all factors except in the denial/defence and minimization stages. Results indicated the effectiveness of SL regarding specific subscales within the IDI instrument. The findings add new depth to our understanding regarding which teaching methodologies contribute to the development of IS and to the training of active citizens in Spanish university students. The discussion focuses on the need for intercultural service experiences to promote IS. The results have broad implications for policymakers and educators who are interested in enhancing transformative educational experiences and effective teaching methodologies for developing students’ IS in higher education.  相似文献

Engineering has been slowly integrated into K-12 science classrooms in the United States as the result of recent science education reforms. Such changes in science teaching require that a science teacher is confident with and committed to content, practices, language, and cultures related to both science and engineering. However, from the perspective of the science teacher, this would require not only the development of knowledge and pedagogies associated with engineering, but also the construction of new identities operating within the reforms and within the context of their school. In this study, a middle school science teacher was observed and interviewed over a period of nine months to explore his experiences as he adopted new values, discourses, and practices and constructed his identity as a reform-minded science teacher. Our findings revealed that, as the teacher attempted to become a reform-minded science teacher, he constantly negotiated his professional identities – a dynamic process that created conflicts in his classroom practices. Several differences were observed between the teacher’s science and engineering instruction: hands-on activities, depth and detail of content, language use, and the way the teacher positioned himself and his students with respect to science and engineering. Implications for science teacher professional development are discussed.  相似文献

Mothers with a substance use disorder (SUD) are at risk for maladaptive parenting practices, and have heightened likelihood of having experienced childhood adversity themselves. In addition, parental reflective functioning (PRF), a capacity underlying sensitive caregiving, is often low in mothers with SUD. This study examines the relationship between PRF and aversive (emotional, physical, sexual abuse and neglect) and adaptive (safety and competence) experiences, in different developmental phases (early childhood, latency, and adolescence) in mothers with a SUD. A sample of 43 mothers with small children were interviewed with the Parental Developmental Interview to assess PRF, and they completed the Traumatic Antecedents Questionnaire regarding aversive and adaptive experiences. In addition, we used the Hopkins Symptoms Checklist-10 to control for mental health status and a battery of neuropsychological tests to control for executive functions. Results indicated that adaptive experiences in early childhood were positively related to PRF, and that experience of emotional abuse was negatively related to PRF. When separating the group of mothers in two sub-groups based on PRF level, results showed that mothers with negative to low PRF had significantly more experiences of adversities in early childhood and latency, and significantly less adaptive experiences in early childhood, latency and adolescence, compared to mothers with moderate to high PRF. In addition, mothers with adequate to high PRF reported experiencing significantly more types of adaptive experiences, and significantly less adversities compared to mothers with negative to low PRF. Results are discussed in relation to developmental trauma, resilience, epistemic trust and mistrust.  相似文献

Mothers who use substances need integrated, multi-sectoral intervention services to support substance use discontinuation. We explored mothers’ service use at Breaking the Cycle, an early intervention and prevention program for pregnant and parenting women and their young children in Toronto, Canada. We conducted retrospective analyses of families’ service records and client charts (N = 160). Aims were to 1) describe women’s use of service, 2) examine how early engagement of pregnant women related to postnatal service use, and 3) examine the circumstances in which women ended their service relationship with Breaking the Cycle. Specifically, we examined circumstances at service ending relating to women’s service goals; custody status with children; and global substance-use, parent-child relationship, and child development outcomes. We found that these vulnerable women were actively engaged in many services and for a long duration, early engagement was associated with greater service use, and greater service use was associated with more positive circumstances upon ending service. Results provide support for a relational approach to service that promotes not only the relationship between mother and child, and mother and service provider, but also highlights relationships among staff, between staff and management, and between community partners as integral to effective service delivery. Integrating positive relationships at all levels is critical to support vulnerable families with complex needs.  相似文献
