Ranking scientific articles based on bibliometric networks with a weighting scheme     

Yu Zhang  Min Wang  Florian Gottwalt  Morteza Saberi  Elizabeth Chang 《Journal of Informetrics》2019,13(2):616-634

As the volume of scientific articles has grown rapidly over the last decades, evaluating their impact becomes critical for tracing valuable and significant research output. Many studies have proposed various ranking methods to estimate the prestige of academic papers using bibliometric methods. However, the weight of the links in bibliometric networks has been rarely considered for article ranking in existing literature. Such incomplete investigation in bibliometric methods could lead to biased ranking results. Therefore, a novel scientific article ranking algorithm, W-Rank, is introduced in this study proposing a weighting scheme. The scheme assigns weight to the links of citation network and authorship network by measuring citation relevance and author contribution. Combining the weighted bibliometric networks and a propagation algorithm, W-Rank is able to obtain article ranking results that are more reasonable than existing PageRank-based methods. Experiments are conducted on both arXiv hep-th and Microsoft Academic Graph datasets to verify the W-Rank and compare it with three renowned article ranking algorithms. Experimental results prove that the proposed weighting scheme assists the W-Rank in obtaining ranking results of higher accuracy and, in certain perspectives, outperforming the other algorithms.  相似文献   

Authorship analysis of specialized vs diversified research output     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Flavia Di Costa 《Journal of Informetrics》2019,13(2):564-573

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines.  相似文献

Exploring Twitter use and services of academic innovation centers     

Besiki Stvilia  Leila Gibradze 《The Journal of Academic Librarianship》2019,45(5):102052

This study examined the Twitter streams and websites of 36 university innovation centers and identified 14 service categories the centers offered. Exploring the present Twitter use practices of innovation centers and the services the centers provide can inform the design and planning of service offerings at new innovation centers and support training for center staff in the use of this social media platform. In addition, existing innovation centers can benchmark their service offerings against those services. Furthermore, mapping the services the innovation centers offer to the activities in an innovation workflow model can help center managers optimize the information architecture of their websites and resource guides. In this way, students can easily be informed about the help and resources available for each activity or phase of the innovation process. A comparison of the tweet categories identified in the present study with those of academic libraries assembled in a previous study revealed significant overlap, but some differences as well. In contrast to the Twitter accounts of academic libraries, the Twitter accounts of innovation centers did not tweet about their information services even if they offered them. Innovation centers also did not use Twitter to provide Q&A services to their users. Furthermore, innovation centers tweeted not only about the technological resources they provided, but also about the human resources they recruited to serve as student mentors and advisors. Finally, technology use was more mediated in innovation centers than in libraries, and some centers offered their users fee-based assistance from professionals with their 3D design and printing tasks.  相似文献   

Public and private value in citizen participation in E-governance: Evidence from a government-sponsored green commuting platform     

Jingrui Ju  Luning Liu  Yuqiang Feng 《Government Information Quarterly》2019,36(4):101400

Citizen participation in E-governance is, essentially, a social exchange between individuals and their government through which the citizen creates public value as well as acquires private value. The direct effects of participation antecedents on participation outcomes have been fully examined, but few researchers have investigated the internal mechanism of citizen participation at the level of psychological value perception. The roles of perceived public and private value between the participation antecedents and outcomes remain unclear. Private value merits careful research in particular as the E-governance environment is being shaped by increasing privatization and continuous IT innovation. Based on the cognitive integration theory and the civic voluntarism model, this paper proposes a theoretical framework to examine the mediating roles of two values. We built a complete research model encompassing ten hypotheses centered on citizen e-participation in the context of green commuting governance. By analyzing survey data on a green commuting platform, we demonstrate the significant mediating effects of these two values and greater effect of private value acquisition on continuous e-participation intentions than public value creation. Our results have important research implications in regards to the roles of perceived values in participation, especially perceived private value.  相似文献   

Continuous usage of e-participation: The role of the sense of virtual community     

Mijail Naranjo-Zolotov  Tiago Oliveira  Sven Casteleyn  Zahir Irani 《Government Information Quarterly》2019,36(3):536-545

Local governments around the world are increasingly implementing e-participation platforms to involve citizens in consultation and decision-making processes. E-participation platforms usually succeed and produce positive effects in the community when adopted in the long-term scenario. The adoption of those platforms is still a challenge for local governments. The understanding of the factors that influence the continuous intention to use e-participation over time is critical for the design of diffusion and promotion strategies that motivate the citizens to keep using e-participation. This article explores the drivers that predict the post-adoption of e-participation platforms from the perspective of the sense of virtual community theory, that is the degree of affective attachment to a given community mediated by information technology. Specifically, our research model evaluates the association between the sense of virtual community with use behaviour and the continuous intention to use e-participation. Structural equation modelling was used to evaluate the data collected from 370 citizens who experienced an e-participation platform hosted by a European capital city. We found out that the direct association between the sense of virtual community and use was significant. Even though the direct association between the sense of virtual community and the continuous intention was non-significant, the indirect association sense of virtual community to use to continuous intention was statistically significant. This finding may indicate that the use behaviour is triggered by the influence of other members of the community for a short period of time, but it does not persist to influence the continuous intention over time.  相似文献   

Academic librarian's transition to blended librarianship: a phenomenology of selected academic librarians in Zimbabwe     

Israel Mbekezeli Dabengwa  Jaya Raju  Thomas Matingwina 《The Journal of Academic Librarianship》2019,45(4):343-357

This paper explores the shared experiences of practices of blended librarianship among Zimbabwean academic librarians to identify how adequately they comply with their dynamic roles and functions. The paper relies on the theoretical constructs from Bell and Shank's (2004, 2007) blended librarianship and Lave and Wenger's (1991) Legitimate Peripheral Participation (LPP) to understand how Zimbabwean academic librarians practice blended librarianship in the workplace through engagement in legitimate work tasks. The investigators used phenomenology to explore academic librarians' experiences of blended librarianship. They selected a sample of 101 academic librarians and delivered a semi-structured questionnaire to the sample, conducted document research and interviewed key informants from the sample. The researchers collected data from the Bindura University of Science Education, Chinhoyi University of Technology, Lupane State University, Midlands State University, the National University of Science and Technology, and PHSBL80 Library which chose to be undisclosed. Each institution adopted blended librarianship in its way. Four (4) different categories of blended librarianship emerged from the experiences; that is “transcending blended librarians”, “partially blended librarians”, “intermittent blended librarians” and “aspiring blended librarians”, displaying each institution's level of instructional technology and instructional design roles. The study proposes that the “Academic librarian's transition to blended librarianship” two-by-two matrix that developed was in this inquiry needs further refinement. Further enquiries may test the matrix within the same sites or other locales altogether to corroborate if the results are replicable.  相似文献   

Research characteristics on health law in China: Social network analysis     

Qing Chang  Chao Long  Mark A. Hall  Zhiguang Duan 《The Journal of Academic Librarianship》2019,45(2):126-136

To determine the nature and extent of the emerging field of “health law” scholarship in China, we retrieved 2956 publications about various aspects of health law published up through 2014 in 268 journals from the “Chinese Social Science Citation Index” and from the list of Chinese “Core Journals” maintained by the Peking University Library. By bibliometric analysis, we observed some interesting results which were different from our expectations. The collaboration network among Chinese health law (CHL) authors was relatively small, loose, unstable and early in its development. Kan Tian and Lixin Yang were leading authors, Renmin University of China was the primary institution, and Beijing was the predominant region studying Chinese health law (CHL). Kan Tian ranked 1st in the collaboration network and Lixin Yang published the most number of articles on CHL. Comprehensive universities made up the majority of institutions studying CHL, while medical colleges did not focus on health law research, possibly due to medical schools focusing mainly on clinical education and not attaching as much importance to social and humanistic aspects of medicine. Food safety, health administration, and the general principles of civil law were the main areas of focus in CHL research, which is basically in line with what we expected.  相似文献   

Student perceptions of information literacy skills and curriculum before and after completing a research assignment     

Lyda Fontes McCartin  Stephanie Evers  Brianne Markowski 《The Journal of Academic Librarianship》2019,45(3):262-267

Library instruction often involves one-shot sessions where librarians interact with students for a short period of time and are then left wondering what the students thought of the session and if students perceive the session as helpful for their course work. Using two surveys to gather data, this study compared student perceptions of a redesigned library curriculum and of their own information literacy skills immediately after attending a library workshop and six weeks later after completing a research paper. The findings indicate that the library workshop is meeting student needs and has a lasting effect. Additionally, the researchers found that students were better able to articulate gaps in their own knowledge after having the opportunity to apply their skills to a research assignment. The researchers recommend that librarians using surveys to inform one-shot curricular changes gather data after students have applied the skills and knowledge gained in the instruction session.  相似文献   

Talent,Schmalent: An Instructional Design/Action Research Framework for the Professionalization of Teaching in Academic Libraries     

Alexander J. Carroll  Kevin Michael Klipfel 《The Journal of Academic Librarianship》2019,45(2):110-118

When myths become canonical beliefs within a professional culture, they can have a profound impact on professional practice. In this paper we identify as a pernicious educational myth the belief that the ability to teach well is a naturally occurring innate talent or skill. The first two sections of the paper aim to demonstrate (i) that the concept of the naturally gifted teacher is a myth based on factually incorrect assumptions about expertise development and (ii) that this myth has several major negative implications for professional practices around teaching in academic libraries. We then we draw on the education literature to offer an alternative model for the cultivation of teaching excellence, an instructional design/action research framework that prioritizes ‘deliberative’ practice over innate talent. We close with suggestions for how academic librarians and library administrators can implement this framework within their institutions.  相似文献
