The Ontario Council of University Libraries (OCUL) is a consortium of the twenty-one university libraries in Ontario, Canada. Since 1967, OCUL member institutions have worked together to share costs and workload through collective purchasing and licensing of information resources and more recently through the establishment of a shared digital infrastructure known as Scholars Portal. Under the auspices of OCUL, Ontario's university map librarians formed the OCUL Map Group in 1973 to seek opportunities to communicate and collaborate to improve the collections and services they offer their users. The opportunities provided by collaboration have ensured a greater capacity to manage evolving collections of geospatial data. The group has served as a community of practice, which has provided educational opportunities and facilitated collaborative problem solving through a listserv, conference calls, and face-to-face meetings. This collegial environment has also led to the completion of a number of projects, which have resulted in the creation of new technical infrastructures and strategies for sharing the workload of data management tasks. This paper discusses the role of collaboration in OCUL projects and offers some suggestions for others considering embarking on collaborations of their own.  相似文献

ABSTRACT

Changes in information communication technology across the Asian region have altered our field substantively and methodologically. The rapid growth of digitized communications allows us to find new purchase in examining questions fundamental to our understanding of communication theories, norms, and practices across Asia. While methods such as text mining and user analytics are increasingly popular among computational scholars, here, we focus on online field experiments, an approach to studying communication that has the potential to overcome many existing obstacles to social scientific inquiry but one that has been used relatively rarely in Asia. In this paper, we discuss what online field experiments are and how they differ from traditional experiments as well as online lab and survey experiments. We show how researchers can go about designing and implementing online field experiments, focusing on issues where online field experiments differ from their traditional counterparts – legal and ethical considerations, construct validity, randomization and spillover, and statistical analyses. Finally we discuss how online field experiments can advance our understanding of communication in Asia by helping researchers to gain insight and make causal inferences on attitudes, behaviors, and interactions that were previously unobservable ?.  相似文献

#MeToo has breathed new life into the women’s movement and especially into understanding and rectifying sexual harassment, abuse and assault. It has galvanized activists around the globe. And it has placed thousands of stories of the harassed in full view of the public. Sexual harassment, abuse and assault may occur within the organizational context or beyond; but sexual harassment, in particular has been legally labeled an organizational phenomenon. With this in mind, Robin Clair frames the early part of this article around the most recent organizational communication theories (see the appendix for an overview of these theories). Following the essay is a forum, in which invited scholars address questions related to the #MeToo movement.  相似文献

在秘鲁安第斯山脉的崇山峻岭中有一座神秘的古城。西班牙人在长达300年的殖民统治期间对它一无所知,秘鲁独立后的100年间也无人涉足。400多年的时光,只有翱翔的山鹰得以一睹古城的雄姿,它就是马丘比丘印加遗址。作为马丘比丘的"姐妹城",肖克奎拉奥可谓是寂寂无名,但却有着马丘比丘无可比拟的孤独与安静。本文作者向我们介绍了在肖克奎拉奥的徒步探险经历,巨石垒筑的残垣断壁正向我们讲述着当年的故事.我们还会感受到怀古的幽思、逝去的光华,以及领略这座古城记载着的印加人无与伦比的智慧。  相似文献
