Search results

The recent proliferation of preprints could be a way for researchers worldwide to increase the availability and visibility of their research findings. Against the background of rising publication costs caused by the increasing prevalence of article processing fees, the search for other ways to publish research results besides traditional journal publication may increase. This could be especially true for lower-income countries.

Therefore, the authors are interested in the experiences and attitudes towards posting and using preprints in the Global South as opposed to the Global North. To explore whether motivations and concerns about posting preprints differ, the authors adopted a mixed-methods approach, combining a quantitative survey of researchers with focus group interviews.

The authors found that respondents from the Global South were more likely to agree to adhere to policies and to emphasise that mandates could change publishing behaviour towards open access. They were also more likely to agree posting preprints has a positive impact. Respondents from the Global South and the Global North emphasised the importance of peer-reviewed research for career advancement.

The study has identified a wide range of experiences with and attitudes towards posting preprints among researchers in the Global South and the Global North. To the authors' knowledge, this has hardly been studied before, which is also because preprints only have emerged lately in many disciplines and countries.

The purpose of this paper is to provide a critical discussion of the Leiden Manifesto for libraries already engaged in bibliometric practices. It offers practical recommendations based on the work of the European Association for Research Libraries (LIBER) Working Group on Metrics. This work is in the beginning phase and summarizes literature on the topic, as well as the experiences of the members of the Working Group. The discussion reflects today's growing popularity of (quantitative) research assessment which is seen in enthusiasts introducing new metrics (i.e. altmetrics) and by critics demanding responsible metrics that increase objectivity and equity in evaluations.

This paper is the result of the Working Group on Metrics of the European Association for Research Libraries (LIBER) that critically discussed the practicality of the Leiden Manifesto for libraries.

Full compliance with the Manifesto is time-consuming, expensive and requires a significant increase in bibliometric expertise with respect to both staffing and skill level. Despite these apparent disadvantages, it is recommended that all libraries embrace the Manifesto’s principles. To increase practicality, it is advised that libraries collaborate with researchers, management and other libraries at home and around the world to jointly design and provide services that can be reused within the library community.

Libraries have increasingly been confronted with questions about research assessment, responsible metrics and the role of digital products in evaluations and funding decisions. Although a wide range of recommendations and initiatives are available (e.g. DORA San Francisco Declaration on Research Assessment), many recommendations are not straightforward enough to be implemented from a library perspective. This paper provides assistance for libraries to implement these principles by acknowledging the heterogeneous backgrounds the libraries may stem from.

Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document‐specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems.

In a theoretical approach the paper discusses document‐specific tag distributions (power law and inverse‐logistic shape), the development of such distributions (Yule‐Simon process and shuffling theory) and introduces search tags (besides the well‐known index tags) as a possibility for generating tag distributions.

Search tags are compatible with broad and narrow folksonomies and with all knowledge organization systems (e.g. classification systems and thesauri), while index tags are only applicable in broad folksonomies. Based on these findings, the paper presents a sketch of an algorithm for mining and processing power tags in information retrieval systems.

This conceptual approach is in need of empirical evaluation in a concrete retrieval system.

Power tags are a new search option for retrieval systems to limit the amount of hits.

The paper introduces power tags as a means for enhancing the precision of search results in information retrieval systems that apply folksonomies, e.g. catalogs in Library 2.0 environments.

Through a theoretical review of the literature, this chapter assesses the potential of different knowledge organisation systems (KOS) to support corporate knowledge management systems (KMS), namely digital libraries (DL) in companies and other institutions. Questions are framed through which the chapter discusses how classical KOS, such as nomenclatures, classification systems, thesauri and ontologies, are able to reflect explicit knowledge in sense of the Semantic Web and also introduces persons as documents along with folksonomies as a means for externalising implicit knowledge in sense of the Web 2.0.

The purpose of this paper is to analyze the tweeting behavior of 37 astrophysicists on Twitter and compares their tweeting behavior with their publication behavior and citation impact to show whether they tweet research-related topics or not.

Astrophysicists on Twitter are selected to compare their tweets with their publications from Web of Science. Different user groups are identified based on tweeting and publication frequency.

A moderate negative correlation (ρ=−0.339) is found between the number of publications and tweets per day, while retweet and citation rates do not correlate. The similarity between tweets and abstracts is very low (cos=0.081). User groups show different tweeting behavior such as retweeting and including hashtags, usernames and URLs.

The study is limited in terms of the small set of astrophysicists. Results are not necessarily representative of the entire astrophysicist community on Twitter and they most certainly do not apply to scientists in general. Future research should apply the methods to a larger set of researchers and other scientific disciplines.

To a certain extent, this study helps to understand how researchers use Twitter. The results hint at the fact that impact on Twitter can neither be equated with nor replace traditional research impact metrics. However, tweets and other so-called altmetrics might be able to reflect other impact of scientists such as public outreach and science communication.

To the best of the knowledge, this is the first in-depth study comparing researchers’ tweeting activity and behavior with scientific publication output in terms of quantity, content and impact.

The purpose of this paper is to examine how age and job identification affect entrepreneurial intention.

The researchers draw on a representative sample of the Austrian adult workforce and apply binary logistic regression on entrepreneurial intention.

The findings reveal that as employees age they are less inclined to act entrepreneurially, and that their entrepreneurial intention is lower the more they identify with their job. Whereas gender, education, and previous entrepreneurial experience matter, leadership and having entrepreneurial parents seem to have no impact on the entrepreneurial intention of employees.

Implications relate to a contingency perspective on entrepreneurial intention where the impact of age is exacerbated by stronger identification with the job.

Practical implications include the need to account for different motivational backgrounds when addressing entrepreneurial employees of different ages. Societal implications include the need to adopt an age perspective to foster entrepreneurial intentions within established organizations.

While the study corroborates and extends findings from entrepreneurial intention research, it contributes new empirical insights to the age and job-dependent contingency perspective on entrepreneurial intention.

The purpose of this paper is to identify governmental social media use in cities with enhanced information and communications technology infrastructures (i.e. Informational World Cities) and high Internet penetration rates. Social media platforms are increasingly being used by governments to foster user interaction and it was investigated if social media platforms are valuable tools for reaching high numbers of citizens.

This paper is based on an iterative content and Web analysis from November 2012 till January 2013 and offers a comparison of different social media service types and the particular use.

This empirical investigation of 31 Informational World Cities provides an overview of social media services used for governmental purposes, of their popularity among governments and of their usage intensity in broadcasting information online. Even as cities in a globalized world become more similar, a variety in the use of social media by governments was detected, which is due to regional and cultural characteristics.

The findings are limited to calculable data, e.g. number of used social media accounts, posts and followers which were available through a content and Web analysis at the time of investigation.

A more detailed content analysis, as well as a more differentiated analysis of users, must be conducted in the future.

This paper is one of the first that presents a global comparison of governmental social media use of cities of the knowledge society and compares different social media platforms.
