Our study compares the motivations of Australian and German book publishers. The results demonstrate remarkable similarities, but also a significant difference regarding the effects of the publishers’ self-concept. In the German case the publishers with a dominant economic orientation are more proactive than the publishers with a dominant cultural orientation. In the Australian case, this correlation does not exist. The same difference holds for the relationship between the economic orientation and extrinsic motivation. We discuss these results and examine empirical evidence and theoretical suggestions to explain the differing findings. The data stem from surveys conducted in the two countries with responses of 196 (Germany) and 54 publishers (Australia). 相似文献

Previous reports stressed on the importance of international collaboration and open access (OA) publishing, as they increase the quality of the research and increase its benefits. In this study, we will assess Jordanian international research collaboration and OA publishing in the past 10 years. We performed a Scopus search for Jordanian publications in the years 2008–2017, where we extracted and calculated the total number of publications, publications in OA journals, publications with international collaborations. Moreover, we assessed the disciplines Jordanians usually publish in. During the 10-year interval, we found a total of 20,359 Jordan-affiliated publications indexed in Scopus. We found a dramatic increase in number of publications with international collaboration from 38% in 2008 reaching 53.3% in 2017, and an increase in OA publications from 7.3% of the total publications in 2008, reaching 18.7% of the total publications in 2017. Total number of Scopus indexed publications from Jordan has increased by 57.9% over the past 10 years. Although international collaboration and OA publications have dramatically increased in recent years, Jordanian researchers should focus more on international collaboration with developed countries and on self-archiving their publications. 相似文献

Nullis in verba was chosen as the motto of the Royal Society, as it embodied the culture of transparency and collaboration that were the hallmarks of the Royal Society and of the scientific method it promoted. Communication, using the tools of the day, was essential to this community of scientists as they created and shared new knowledge. Almost three hundred years later, libraries continue to advance principles relating to the importance of collaboration and transparency. This two-part article series, published jointly in International Information and Library Review and Technical Services Quarterly explores notions of transparency and collaboration in research and how these ideas are impacting the world of librarianship – from information creation, organization and access perspectives. 相似文献

There are a number of challenges unique to the children’s book sector faced by publishers in today’s digitally-dominant business market, making it more crucial than ever for children’s book marketers to create multifaceted marketing plans that include differing but complementary approaches. Among the common marketing challenges specific to children’s books are overabundance of content, competition, access to the library market, the digital versus print dichotomy, difficulty of marketing directly to young readers on the Internet, and the dual (child and adult) target audience. While some marketing tactics must effectively attract the attention of the child reader, it is of fundamental importance (with some exceptions) for publishers, authors, and marketers of children’s books to also ensure their marketing techniques target the adult gatekeepers who are likely to purchase those books. Depending upon various factors, including age range of the reader and subject matter, marketers of children’s books are most successful when applying a mix of traditional and digital marketing techniques. 相似文献

The purpose of this study is to investigate the elements of Islamic children’s books that are written in English by focusing on books that are available in the Malaysian market and published in Malaysia. This study applies the content analysis method, by examining the selected books of their subject matter as well as the language. The results of the study reveal that Islamic books written for children in English are distinctive in terms of the content and language features. 相似文献

The mere perception that news has given certain problems more coverage can lead the audience to assume that those problems are more important. Given that the news media, at times, obsesses over relatively trivial matters, and given that the audience is increasingly able to filter media exposure, it is worth asking what happens when audience members perceive that recent media coverage has not emphasized any very important problems. In such cases, audience members might assume that any problems facing the nation must not be particularly important. We explicate this attitude of political complacency, test whether perceived media agendas lacking important problems can influence it, and explore whether complacency helps explain political disengagement. We also explore whether these effects generalize beyond news, to new media gatekeepers such as Twitter. Two experiments tested effects of a perceived absence of important problems in recent news or Twitter content. In the case of news, but not Twitter, this increased complacency in both studies. Study 2 added a no-exposure control and found that effects on complacency were driven by the cueing of nonproblem stories, not by the absence of problem story cues. Both studies validated complacency as a predictor of political disengagement. 相似文献
