ABSTRACT

This article examines the role that business librarians can play in conveying the importance of thorough patent research in the start-up life cycle. It provides a summary of the components of the start-up life cycle and due diligence research as it pertains to entrepreneurs and venture capitalists. An overview of patent research resources and locations is provided, with particular focus on PatentsView, a web-based patent data visualization and analysis tool.  相似文献

ABSTRACT

This article describes a program session about licensing electronic resources. The speakers discussed a range of licenses in the current electronic resources landscape and described current trends in the negotiation and management of licenses. They also explored the impact of workflow design on the accessibility of electronic resources at any institution.  相似文献

Multimedia pedagogical agents are on-screen characters that allow users to navigate or learn in multimedia environments. Several agents’ characteristics may moderate their instructional effectiveness, including appearance, gender, nonverbal communication, motion, and voice. Here, we conducted a meta-analysis to test hypotheses from diverse theories predicting the effects of these agents’ characteristics. We tested predictions of cognitive load theory, cognitive theory of multimedia learning, computers are social actors, social agency theory, uncanny valley, and the action observation network. Our meta-analysis of 32 effect sizes (N?=?2104) revealed a small overall effect (g+?=?0.20), showing that learning with multimedia pedagogical agents was more effective than learning without these agents. As predicted by the redundancy effect of cognitive load theory and the coherence principle of cognitive theory of multimedia learning, 2D agents (g+?=?0.38) tended to be more effective than 3D agents (g+?=?0.11). As predicted by the computers are social actors hypothesis, most of the agents’ characteristics, including nonverbal communication, motion, and voice, appeared not to moderate their effectiveness. We conclude that multimedia pedagogical agents help learning through multimedia, and that students may be able to learn similarly from different types of agents.

Teachers are more likely to be found in rural communities and low-wage metropolitan areas than are college-educated workers in other occupations. This analysis explores the extent to which the geographic distribution of teachers explains the relatively low average wage found in other studies. The analysis suggests that excluding geographic indicators from the analysis downwardly biases estimates of relative teacher wages. One important implication of these findings is that researchers should pay attention to geographic wage variations when making earnings comparisons between teaching and other occupations.  相似文献

A mixed methods approach was used to explore secondary teachers’ motivation beliefs in Canada and Singapore. Results from Study 1 revealed that socio-economic status (SES) was the strongest predictor of school climate in Canada, and that collective efficacy mediated the effect of SES on school climate in Singapore, but not in Canada. In Study 2, interviews were conducted with 10 teachers in Canada and 14 teachers in Singapore. Teachers in both settings discussed students’ social and behavior problems, but the range of the social problems was greater in Canada than in Singapore, and had a stronger impact on teachers’ motivation beliefs.  相似文献

Despite extensive research supporting educational acceleration for students with high academic ability, some psychologists, counselors, and educators express concerns about accelerative interventions. Such concerns often hinge on uncertainty about social acceptance, even in inclusive education settings. Research on acceleration has consistently shown benefits for students with high ability; however, there is a lack of research about grade‐based acceleration in inclusive schools. This study engaged two groups of students in group concept mapping processes to examine how they conceptualized beliefs about grade‐based acceleration in inclusive schools. First, 26 students in inclusive classes generated beliefs about grade‐based acceleration. Then they, and a group of 14 students with high ability, structured the data by sorting and rating a synthesized list of the generated beliefs. We analyzed the sorted data using multidimensional scaling and hierarchical cluster analysis. The resultant cluster maps revealed some differences and some similarities in the ways that the two groups of students conceptualized beliefs about educational acceleration. Practical implications are discussed.  相似文献
