This article reports on a video project done in an academic library where faculty were included in the production and marketing of the library instruction videos. The videos allowed the librarian to provide a shorter presentation and spend most of her time working individually with each student. The results showed that 97% of the students watched the videos and were able to benefit from the content. The implementation of the videos was a success due to the collaboration of the professors teaching the three courses and the buy-in of the course coordinator; both factors were essential in the success of the video project. 相似文献

Recommender Systems are currently highly relevant for helping users deal with the information overload they suffer from the large volume of data on the web, and automatically suggest the most appropriate items that meet users needs. However, in cases in which a user is new to Recommender System, the system cannot recommend items that are relevant to her/him because of lack of previous information about the user and/or the user-item rating history that helps to determine the users preferences. This problem is known as cold-start, which remains open because it does not have a final solution. Social networks have been employed as a good source of information to determine users preferences to mitigate the cold-start problem. This paper presents the results of a Systematic Literature Review on Collaborative Filtering-based Recommender System that uses social network data to mitigate the cold-start problem. This Systematic Literature Review compiled the papers published between 2011–2017, to select the most recent studies in the area. Each selected paper was evaluated and classified according to the depth which social networks used to mitigate the cold-start problem. The final results show that there are several publications that use the information of the social networks within the Recommender System; however, few research papers currently use this data to mitigate the cold-start problem. 相似文献

ABSTRACTLibraries use surveys and other instruments to gather feedback from their users. However, with competition from many other campus entities requesting input, how can survey fatigue be avoided? To gather this feedback, the Social Sciences Reference Desk utilized a short, fun and easy method. Each week for 10 weeks during the fall semester of 2017, the reference assistants wrote a survey question on a whiteboard and provided sticky notes for patrons to write their answers. The survey provided valuable information about patrons’ needs and expectations. It also fostered changes that were easily implemented to improve the delivery of library services. 相似文献

Purpose: The main purpose of this study was to investigate the influence of fatigue on musculoarticular stiffness (MAS) of the ankle joint across sexes. Methods: Twenty-seven males and 26 females participated in the study. After baseline assessment of MAS and related variables, localised fatigue was induced in triceps surae using the standing heel-rise test during which the subjects were instructed to lift and drop the heel at a frequency of 0.5?Hz. When subjects were unable to continue due to exhaustion the test was terminated and another MAS test was performed soon after. Results: Significant higher triceps surae MAS was found in men compared to women (p?p??1 and from 14.5 to 13.9?KN?m?1 in men and women, respectively. Percentage changes revealed, however, that in relative terms the changes in all the variables evaluated were similar (p?>?.01) between sexes, with MAS less than 5%. Conclusion: Despite the sex-related differences at baseline, fatigue seems to affect biomechanical properties of the ankle joint similarly in men and women. 相似文献

The aim of this paper is to address the teaching and learning processes in schools from a Vygotskian perspective based on the notion of identity artefacts (IAs) which, for our purposes, consist of documents created by the learners about themselves, in which they try to capture all the things that make sense and are meaningful to them and which, subsequently, can be used by teachers to work on curricular and pedagogical content. We conceptualise the notion of the identity artefact from the broader notions of mediation and cultural artefacts. We also provide a critical analysis of some examples of IAs. 相似文献

In this paper, we argue that reflecting upon our personal experiences and the origins of our ethical and political beliefs can be useful to see that, as much as society has a strong influence on us, each of us has the capacity to influence society. Also we suggest that there exist intimate links between personhood and pedagogy. As such, through the use of bio-pedagogical passages, we examine the process of coming to the realisation of the need to develop ethical principles that enable us to contribute to society in universally beneficial ways through our teaching. Moreover, we explain that, as they try to help prospective educators understand their future role in society, physical education teacher educators (PETEs) ought to start with clear ethical principles, not just merely technical (or even scientific) ones. These principles, in turn, can serve as a guide for all pedagogical (read political) actions, both inside and outside the classroom. We close this paper offering viable guidelines as to how this can be done. 相似文献
