The data for the study were culled out from African Index Medicus (AIM) database. A total of 529 articles was gathered from 115 journal titles from 1979-2011. In order to obtain the core of productive journals, Bradford`s law was applied to the collected data. Five journal titles were identified and determined as core journals. The data used for the study was analyzed and that, the subject matter used, Malaria was in conformity with the Bradford`s law. On the aspect dispersion of the literature, English was found to be the dominant language of the journals. (80.9%) followed by French (16.5%). Followed by Portuguese (1.7%) and German (0.9%). Recommendation is hereby proposed for the medical libraries to acquire these five journals that constitute the core in malaria literature for the use of their clients. It could also help in streamlining their acquision and selection exercises. More researches in the subject area using Bibliometrics approaches are hereby recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=productive%20journals" title="productive journals">productive journals</a>, <a href="https://publications.waset.org/abstracts/search?q=malaria%20disease%20literature" title=" malaria disease literature"> malaria disease literature</a>, <a href="https://publications.waset.org/abstracts/search?q=Bradford%60s%20law" title=" Bradford`s law"> Bradford`s law</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20journals" title=" core journals"> core journals</a>, <a href="https://publications.waset.org/abstracts/search?q=African%20scholars" title=" African scholars "> African scholars </a> </p> <a href="https://publications.waset.org/abstracts/13963/journals-productivity-in-the-literature-on-malaria-in-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13963.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2289</span> Open Minds but Closed Access: Why Are There so Few Gold Open Access LIS Journals And Why Are so Many Librarians Unwilling to Unlock Their Scholarship?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Baker">Sarah Baker</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayati%20Chaudhuri"> Jayati Chaudhuri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Librarians have embraced the open access movement in all disciplines but their own. They are strong advocates on college campuses and curate institutional repositories, yet there are surprisingly few open access LIS journals. Presenters evaluated the open access availability of library and information science literature. After analyzing the top 100 library science journals (the top 50 journals from Scimago and JCR) and finding very few gold open access journals, they then investigated the availability of open access articles from the top 10 closed access journals. Presenters would like to generate a conversation on what type of proactive approach librarians can take to increase open access to literature within our discipline. Librarians like their colleagues in other disciplines are not motivated to submit their articles to their institutional repositories. Presenters have found a similar reluctance from their fellow colleagues regarding open access initiatives on campus. Presenters will describe Open Access Week activities as part of a campus-wide initiative and share some faculty comments, concerns, and misconceptions that came up as a part of this dialog. Presenters will discuss their personal experiences providing access to faculty publications through the California State University Los Angeles institutional repository. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=faculty%20scholarship" title="faculty scholarship">faculty scholarship</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20repositories" title=" institutional repositories"> institutional repositories</a>, <a href="https://publications.waset.org/abstracts/search?q=library%20and%20information%20science%20journals" title=" library and information science journals"> library and information science journals</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20access" title=" open access"> open access</a> </p> <a href="https://publications.waset.org/abstracts/26157/open-minds-but-closed-access-why-are-there-so-few-gold-open-access-lis-journals-and-why-are-so-many-librarians-unwilling-to-unlock-their-scholarship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2288</span> Measuring the Visibility of the European Open Access Journals with Bibliometric Indicators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maja%20Joki%C4%87">Maja Jokić</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Mervar"> Andrea Mervar</a>, <a href="https://publications.waset.org/abstracts/search?q=Stjepan%20Mateljan"> Stjepan Mateljan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Peer review journals, as the main communication channel among researchers, fully achieve their objective if they are available to the global research community, which is accomplished through open access. In the EU countries, the idea of open access has spread over the years through various projects, initiatives, and strategic documents. Consequently, in this paper we want to analyze, using various bibliometric indicators, visibility, and significance of open access peer review journals compared to the conventional (non-open access) ones. We examine the sample of open access (OA) journals in 28 EU countries in addition to open access journals in three EU candidate countries (Bosnia and Herzegovina, FYR Macedonia and Serbia), all indexed by Scopus (N=1,522). These journals comprise 42% of the total number of OA journals indexed by Scopus. The distribution of OA journals in our sample according to the subject fields indicates that the largest share has OA journals in Health Sciences, 29% followed by Social Sciences and Physical Sciences with 25%, and 21% in Life Sciences. At the same time, the distribution according to countries (N=31) shows the dominance of EU15 countries with the share of 68.3% (N=1041) while post-socialist European countries (EU11 plus three candidate EU countries) have the share of 31.6% (N=481). Bibliometric indicators are derived from the SCImago Journal Ranking database. The analysis of OA journals according to their quartile scores (that reflect the relation between number of articles and their citations) shows that the largest number of OA journals from our sample was in the third quartile in 2015. For comparison, the majority of all academic journals indexed in Scopus from the countries in our sample were in the same year in the first quartile. The median of SJR indicator (SCImago Journal Rankings) for 2015 that measures the journal's prestige, amounted 0.297 for OA journals from the sample, while it was modestly lower for all OA journals, 0.284. The value of the same indicator for all journals indexed by Scopus (N=11,086) from our group of countries was 0.358, which is significantly different from the one for OA journals. Apart from the number of OA journals we also confirm significant differences between EU15 and post-socialist countries in bibliometric status of OA journals. The median SJR indicator for 2015 for EU15 countries was 0.394, while for post-socialist countries it amounted to 0.226. The changes in bibliometric indicators: quartile score, SJR (SCImago Journal Rankings), SNIP (Sources Normalised Impact by Paper) and IPP (Impact per Publication) of OA journals during 2012-2015 period, as well as H-index for the main four subject fields (Life Sciences, Physical Sciences, Social Sciences and Health Sciences) in the whole sample as well as in two main groups of European countries, show increasing trend of acceptance and visibility of OA journals within the academic community. More comprehensive insights into the visibility of OA journals could be reached by using additional qualitative research methods such as for example, interviews with researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bibliometric%20analysis" title="bibliometric analysis">bibliometric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20countries" title=" European countries"> European countries</a>, <a href="https://publications.waset.org/abstracts/search?q=journal%20evaluation" title=" journal evaluation"> journal evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20access%20journals" title=" open access journals "> open access journals </a> </p> <a href="https://publications.waset.org/abstracts/59923/measuring-the-visibility-of-the-european-open-access-journals-with-bibliometric-indicators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2287</span> Seismic Behavior of Short Core Buckling Restrained Braces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nader%20Hoveidae">Nader Hoveidae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the seismic behavior of a new type of buckling restrained braces (BRBs) called "Short Core BRBs" in which a shorter core segment is used as an energy dissipating part and an elastic part is serially connected to the core. It seems that a short core BRB is easy to be fabricated, inspected and replaced after a severe earthquake. In addition, the energy dissipating capacity in a short core BRB is higher because of larger core strains. However, higher core strain demands result in high potential of low-cycle fatigue fracture. In this paper, a strategy is proposed to estimate the minimum core length in a short core BRBs. The seismic behavior of short core buckling restrained brace is experimentally examined. The results revealed that the short core buckling restrained brace is able to sustain large inelastic strains without any significant instability or strength degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=short%20core" title="short core">short core</a>, <a href="https://publications.waset.org/abstracts/search?q=Buckling%20Restrained%20Brace" title=" Buckling Restrained Brace"> Buckling Restrained Brace</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20test" title=" cyclic test"> cyclic test</a> </p> <a href="https://publications.waset.org/abstracts/37090/seismic-behavior-of-short-core-buckling-restrained-braces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37090.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2286</span> NFC Kenaf Core Graphene Paper: In-situ Method Application </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Izzati">M.

Past studies have shown reporting quality to be lacking in the field of surgery. Reporting guidelines are an important tool for authors to optimize the reporting of their research. The objective of this study was to analyse the frequency and strength of recommendation for such reporting guidelines within surgical journals. Methods: A systematic review of the 198 journals within the Journal Citation Report 2014 (surgery category) published by Thomson Reuters was undertaken. The online guide for authors for each journal was screened by two independent groups and results were compared. Data regarding the presence and strength of recommendation to use reporting guidelines was extracted. Results: 193 journals were included (as five appeared twice having changed their name). These had a median impact factor of 1.526 (range 0.047 to 8.327), with a median of 145 articles published per journal (range 29-659), with 34,036 articles published in total over the two-year window 2012-2013. The majority (62%) of surgical journals made no mention of reporting guidelines within their guidelines for authors. Of the journals (38%) that did mention them, only 14% (10/73) required the use of all relevant reporting guidelines. The most frequently mentioned reporting guideline was CONSORT (46 journals). Conclusion: The mention of reporting guidelines within the guide for authors of surgical journals needs improvement. Authors, reviewers and editors should work to ensure that research is reported in line with the relevant reporting guidelines. Journals should consider hard-wiring adherence to them. This will allow peer-reviewers to focus on what is present, not what is missing, raising the level of scholarly discourse between authors and the scientific community and reducing frustration amongst readers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CONSORT" title="CONSORT">CONSORT</a>, <a href="https://publications.waset.org/abstracts/search?q=guide%20for%20authors" title=" guide for authors"> guide for authors</a>, <a href="https://publications.waset.org/abstracts/search?q=PRISMA" title=" PRISMA"> PRISMA</a>, <a href="https://publications.waset.org/abstracts/search?q=reporting%20guidelines" title=" reporting guidelines"> reporting guidelines</a>, <a href="https://publications.waset.org/abstracts/search?q=journal%20impact%20factor" title=" journal impact factor"> journal impact factor</a>, <a href="https://publications.waset.org/abstracts/search?q=citation%20analysis" title=" citation analysis"> citation analysis</a> </p> <a href="https://publications.waset.org/abstracts/40184/support-for-reporting-guidelines-in-surgical-journals-needs-improvement-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40184.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">465</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2284</span> Gender and Geographical Disparity in Editorial Boards of Lithuanian Scientific Journals: An Overview of Different Science Disciplines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrius%20Suminas">Andrius Suminas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Editors-in-chief and members of editorial boards of scientific journals play an extremely important role in the development of science and assure research integrity, as scientific publications are the major results of research. While gender parity in tenure-track hiring decisions and promotion rates has improved, female academics remain underrepresented in senior career phases, including editors-in-chief and members of editorial boards positions of scientific journals. Journal editors and members of editorial boards exert considerable power over what is published and in certain cases the direction of an academic discipline and the career advancement of authors. For this reason it is important to minimize biases extrinsic to the merit of the work impacting publication decisions. One way to achieve this is to ensure a diverse pool of editors and members of editorial boards, ensuring the widest possible coverage of different competencies. This is in line with a diversity model of editorial appointment where editorial boards are structured to dismantle wider conditions of inequality. Another possible option, a distributive model would seek an editorial board reflective of existing proportions in the field at large. Paper presents comprehensive results of Lithuanian scientific journals study. During the research process were reviewed publicly available information from all scientific journals published in Lithuania to infer the proportions of members of editorial boards by gender and country of affiliation. The results of the study revealed differences the proportions of male and female members of editorial boards in different disciplines of science, as well as clear geographical disparity in Lithianian scientific journals editorial boards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scientific%20journals" title="scientific journals">scientific journals</a>, <a href="https://publications.waset.org/abstracts/search?q=editorial%20boards%20of%20scientific%20journals" title=" editorial boards of scientific journals"> editorial boards of scientific journals</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20disparity" title=" gender disparity"> gender disparity</a>, <a href="https://publications.waset.org/abstracts/search?q=geographical%20disparity" title=" geographical disparity"> geographical disparity</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20communication" title=" scientific communication"> scientific communication</a> </p> <a href="https://publications.waset.org/abstracts/159332/gender-and-geographical-disparity-in-editorial-boards-of-lithuanian-scientific-journals-an-overview-of-different-science-disciplines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159332.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2283</span> Towards a Broader Understanding of Journal Impact: Measuring Relationships between Journal Characteristics and Scholarly Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=X.%20Gu">X.

Various impact measures exist from multiple bibliographic databases. In this research, we aim to provide a broader understanding of the relationship between scholarly impact and other characteristics of academic journals. Data used for this research were collected from Ulrich’s Periodicals Directory (Ulrichs), Cabell’s (Cabells), and SCImago Journal & Country Rank (SJR) from 1999 to 2015. A master journal dataset was consolidated via Journal Title and ISSN. We adopted a two-step analysis process to study the quantitative relationships between scholarly impact and other journal characteristics. Firstly, we conducted a correlation analysis over the data attributes, with results indicating that there are no correlations between any of the identified journal characteristics. Secondly, we examined the quantitative relationship between scholarly impact and other characteristics using quartile analysis. The results show interesting patterns, including some expected and others less anticipated. Results show that higher quartile journals publish more in both frequency and quantity, and charge more for subscription cost. Top quartile journals also have the lowest acceptance rates. Non-English journals are more likely to be categorized in lower quartiles, which are more likely to stop publishing than higher quartiles. Future work is suggested, which includes analysis of the relationship between scholars and their publications, based on the quartile ranking of journals in which they publish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20journal" title="academic journal">academic journal</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance%20rate" title=" acceptance rate"> acceptance rate</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20factor" title=" impact factor"> impact factor</a>, <a href="https://publications.waset.org/abstracts/search?q=journal%20characteristics" title=" journal characteristics"> journal characteristics</a> </p> <a href="https://publications.waset.org/abstracts/60464/towards-a-broader-understanding-of-journal-impact-measuring-relationships-between-journal-characteristics-and-scholarly-impact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2282</span> Classifying the Role of Technology in Technology Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Joung%20No">Hyun Joung No</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul%20Lee"> Chul Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Even though technology evolves and develops through interaction with each other, not all technologies contribute to the development of technology equally. While some technologies play a central role in developing technology, others play a secondary role. The role of the technological components can be classified as core or non-core (peripheral) technology. The core technologies have a considerable knowledge interaction with other technological components while the non-core technologies barely interact with others within the system. This study introduces the concept that classifies the technological components into core or peripheral technology according to their role and importance in the technology field. The study adapted the social network analysis to examine the relationship between technological components. Using a continuous core-periphery analysis, it identifies the technological network structure and classifies the core and peripheral nodes. Based on their knowledge inflow/outflow direction and their dependence/influence on core technologies, the technological clusters are classified into four categories: (1) high dependence and high influence on core technology, (2) high dependence and low influence on core technology, (3) low dependence and high influence on core technology, and (4) low dependence and low influence on core technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20technology" title="core technology">core technology</a>, <a href="https://publications.waset.org/abstracts/search?q=periphery%20technology" title=" periphery technology"> periphery technology</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20components" title=" technological components"> technological components</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20role" title=" technological role"> technological role</a> </p> <a href="https://publications.waset.org/abstracts/79729/classifying-the-role-of-technology-in-technology-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79729.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">538</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2281</span> An Overview of College English Writing Teaching Studies in China Between 2002 and 2022: Visualization Analysis Based on CiteSpace</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Yiting">Yang Yiting</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper employs CiteSpace to conduct a visualiazation analysis of literature on college English writing teaching researches published in core journals from the CNKI database and CSSCI journals between 2002 and 2022.

Such growing interest motivates this article, aiming to explore the most influential journals, publishers, categories, and topics, as well as the recent trends and future research lines in GPP. Based on the Web of Science database, 578 articles from 2004 to February 2022 devoted to GPP are analyzed using Bibliometrix, an R-tool to perform bibliometric analysis, and Google’s Big Query and Data Studio. This article introduces a variety of findings. First, the most influential journals by far are “Journal of Cleaner Production” and “Sustainability,” differing in that the latter is open access while the former publishes via traditional subscription. This result also occurs regarding the main publishers (Elsevier and MDPI). These features lead us to split the sample into open-access journals and traditional journals to deepen into the similarities and differences between them, confirming that traditional journals exhibit a higher degree of influence in the literature than their open-access counterparts in terms of the number of documents, number of citations and impact (according to the H index). Second, this research also highlights the recent emergence of green-related terms (sustainable, environment) and, parallelly, the increase in categorizing GPP papers in “green” WoS categories, particularly since 2019. Finally, a number of related topics are emerging and will lead the research, such as food security, infrastructures, and implementation barriers of GPP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bibliometric%20analysis" title="bibliometric analysis">bibliometric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20public%20procurement" title=" green public procurement"> green public procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20access" title=" open access"> open access</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20journals" title=" traditional journals"> traditional journals</a> </p> <a href="https://publications.waset.org/abstracts/157465/green-public-procurement-in-open-access-and-traditional-journals-a-comparative-bibliometric-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157465.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2279</span> Altmetrics of South African Journals: Implications for Scholarly Impact of South African Research on Social Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omwoyo%20Bosire%20Onyancha">Omwoyo Bosire Onyancha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Journal Citation Reports (JCR) of the Thomson Reuters has, for decades, provided the data for bibliometrically assessing the impact of journals. In their criticism of the journal impact factor (JIF), a number of scholars such as Priem, Taraborelli, Groth and Neylon (2010) observe that the “JIF is often incorrectly used to assess the impact of individual articles. It is troubling that the exact details of the JIF are a trade secret, and that significant gaming is relatively easy”. The emergence of alternative metrics (Altmetrics) has introduced another dimension of re-assessing how the impact of journals (and other units such as articles and even individual researchers) can be measured. Altmetrics is premised upon the fact that research is increasingly being disseminated through social network sites such as ResearchGate, Mendeley, Twitter, Facebook, LinkedIn, and ImpactStory, among others. This paper adopts informetrics (including altmetrics) techniques to report on the findings of a study conducted to investigate and compare the social media impact of 274 South Africa Post Secondary Education (SAPSE)-accredited journals, which are recognized and accredited by the Department of Higher Education and Training (DHET) of South Africa (SA). We used multiple sources to extract data for the study, namely Altmetric.com and the Thomson Reuters’ Journal Citation Reports. Data was analyzed in order to determine South African journals’ presence and impact on social media as well as contrast the social media impact with Thomson Reuters’ citation impact. The Spearman correlation test was performed to compare the journals’ social media impact and JCR citation impact. Preliminary findings reveal that a total of 6360 articles published in 96 South African journals have received some attention in social media; the most commonly used social media platform was Twitter, followed by Mendeley, Facebook, News outlets, and CiteULike; there were 29 SA journals covered in the JCR in 2008 and this number has grown to 53 journals in 2014; the journals indexed in the Thomson Reuters performed much better, in terms of their altmetrics, than those journals that are not indexed in Thomson Reuters databases; nevertheless, there was high correlation among journals that featured in both datasets; the journals with the highest scores in Altmetric.com included the South African Medical Journal, African Journal of Marine Science, and Transactions of the Royal Society of South Africa while the journals with high impact factors in JCR were South African Medical Journal, Onderstepoort: Journal of Veterinary Research, and Sahara: Journal of Social Aspects of HIV-AIDS; and that Twitter has emerged as a strong avenue of sharing and communicating research published in the South African journals. Implications of the results of the study for the dissemination of research conducted in South Africa are offered. Discussions based on the research findings as well as conclusions and recommendations are offered in the full text paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=altmetrics" title="altmetrics">altmetrics</a>, <a href="https://publications.waset.org/abstracts/search?q=citation%20impact" title=" citation impact"> citation impact</a>, <a href="https://publications.waset.org/abstracts/search?q=journal%20citation%20reports" title=" journal citation reports"> journal citation reports</a>, <a href="https://publications.waset.org/abstracts/search?q=journal%20impact%20factor" title=" journal impact factor"> journal impact factor</a>, <a href="https://publications.waset.org/abstracts/search?q=journals" title=" journals"> journals</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=scholarly%20publishing" title=" scholarly publishing"> scholarly publishing</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media%20impact" title=" social media impact"> social media impact</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/50640/altmetrics-of-south-african-journals-implications-for-scholarly-impact-of-south-african-research-on-social-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50640.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">204</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2278</span> Ways for Improving Citation of the Cyrillic Publications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Y.%20Garnova">Victoria Y.

While PDF is to the author’s best knowledge probably the most popular digital format of XXI century, but there are more formats available: HTML, EPUB, etc. Our aim is to analyze how these formats important to the readers and what is their contribution to scientific communication. We want to investigate how printed journals are still popular between scholars and does different formats are preferred between fields of science . In most cases, publishing of scientific journals are examined from a narrow perspective of a particular university science affair administrators or research funding institution. We believe that more data o n formats used in scholarly periodicals currently published in Lithuania as well as in Eastern Europe are needed. Science communication is often analyzed as a directed chain of information in the author-publisher-reader cycle. The paper is focusing on the publishing part of this chain. A distinction is made between formal and informal forms of scientific communication, which is relevant in today's context, when both forms of communication intertwine and complement each other. In our research, we will analyze formal documentary (formats of publication of scientific articles) communication - scientific information recorded in a certain medium and formatted in certain format (printed, PDF, HTML, EPUB, etc.). In our research, we will analyze the stage of publication of research results in scientific journals and their dissemination through specific publication formats. The paper is to systematize and analyze the various types of formats of scientific journal published in XXI century in Lithuania (small publishing market).

The photoluminescence (PL) quantum yield (QY) of core-shell QDs increases with respect to the core, indicating that the radiative rate increases by the formation of shell around core, as evident by the measurement of PL lifetime. Further, the PL of bovine serum albumin is quenched strongly by the presence of core-shall QDs and follow the Stern-Volmer (S-V) relation, whereas the lifetime does not follow the S-V relation, demonstrating that the observed quenching is predominantly static in nature. Among all the QDs, the CdSe/ZnS QDs shows the least cytotoxicity hence most biocompatibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=core-shell%20quantum%20dots" title=" core-shell quantum dots"> core-shell quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence%20and%20lifetime" title=" photoluminescence and lifetime"> photoluminescence and lifetime</a>, <a href="https://publications.waset.org/abstracts/search?q=sensing%20ability" title=" sensing ability"> sensing ability</a> </p> <a href="https://publications.waset.org/abstracts/56638/biocompatibility-and-sensing-ability-of-highly-luminescent-synthesized-core-shell-quantum-dots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">236</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2273</span> Local Buckling of Web-Core and Foam-Core Sandwich Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20N.%20Suri">Ali N.

In this study local buckling of web core and web-foam core Sandwich panels is carried out for given materials of facing and core, and given panel overall dimension for different combinations of cross section geometries. The Finite Strip Method is used for the analysis, and Fortran based computer program is developed and used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=local%20buckling" title="local buckling">local buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20strip" title=" finite strip"> finite strip</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20panels" title=" sandwich panels"> sandwich panels</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20and%20foam%20core" title=" web and foam core"> web and foam core</a> </p> <a href="https://publications.waset.org/abstracts/7299/local-buckling-of-web-core-and-foam-core-sandwich-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7299.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2272</span> Exploring the Changes in the Publishing of Scientific Journals in the Age of Digital Transformation as the Main Measure for Scientific Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ar%C5%ABnas%20Gudinavi%C4%8Dius">Arūnas Gudinavičius</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The historiography of scholarly journals in Eastern Europe is fragmented, and so far, the development of scholarly journals in Eastern Europe has not been studied from a publishing point of view in the context of scientific communication. There are only a few general articles on the period before World War II; also, there is hardly any systematic and publicly available information about the Soviet period and the situation of scientific communication in Eastern Europe at the end of the XX century and the beginning of the XXI century. There is a lack of research data on scholarly journals in Lithuania. The existing researches focuses mostly on the specific needs of academic institutions. The publication of scientific journals and papers is analyzed as a part of the scientific communication circle. Formal science communication from the point of view that it is the results formed in the course of communication are examined, which are necessarily characterized by long-term access to a large circle of users. Improved model of scientific communication by supplementing the dissemination of research results with formal and informal communication channels is used, according to which the scientific communication system forms the essence of science, where the social, lasting value of science and the dissemination of scientific results to scientists and the public are the most important. The model covers the science communication process from research initiation to journal publication and citation. We are focusing on the publishing and dissemination stages of the model of scientific communication. The paper is to systematize and analyze the various types of scientific journal publishers from 1907 until 2020 as a means of formal documentary communication in the context of all scientific communication. The research analyses the case of a small European country and presents chronological and geographical characteristics of the publication of scientific periodicals, analyzes the publishers of scientific periodicals and their activities, publishing formats, and dissemination methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scientific%20communication" title="scientific communication">scientific communication</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20periodicals" title=" scientific periodicals"> scientific periodicals</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20journals" title=" scientific journals"> scientific journals</a>, <a href="https://publications.waset.org/abstracts/search?q=publishing" title=" publishing"> publishing</a> </p> <a href="https://publications.waset.org/abstracts/159268/exploring-the-changes-in-the-publishing-of-scientific-journals-in-the-age-of-digital-transformation-as-the-main-measure-for-scientific-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159268.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2271</span> Identification of Transformer Core Vibrations and the Effect of Third Harmonic in the Electricity Grid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Setareh%20Gorji%20Ghalamestani">Setareh Gorji Ghalamestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Lieven%20Vandevelde"> Lieven Vandevelde</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Melkebeek"> Jan Melkebeek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, an experimental technique is applied for the measurements of the vibrations and deformation of a test transformer core.

Core strength means to strengthen the muscles deep within the abdomen which connect to the spine and pelvis which control the position and movement of the central portion of the body. Strengthening of core muscles is important for injury prevention (lower back pain) and performance enhancement in sports. The purpose of the study was to review the literature and findings on the effects of Yoga exercise as a part of sports training method and fitness programs. Fifteen papers were found to be relevant for this review. There are five simple yoga poses: Ardha Phalakasana (Low plank), Vasisthasana (side plank), Purvottanasana (inclined plane), Sarvangasana (shoulder stand), and Virabhadrasana (Warrior) are found to be very effective for strengthening core muscles. They are the most effective poses to build core strength and flexibility to the core muscles. The study suggests that sports and fitness trainers should include these yoga exercises in their programs to strengthen core muscles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20strength" title="core strength">core strength</a>, <a href="https://publications.waset.org/abstracts/search?q=yoga" title=" yoga"> yoga</a>, <a href="https://publications.waset.org/abstracts/search?q=injuries" title=" injuries"> injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=lower%20back" title=" lower back"> lower back</a> </p> <a href="https://publications.waset.org/abstracts/57946/a-comprehensive-review-of-yoga-and-core-strength-strengthening-core-muscles-as-important-method-for-injury-prevention-lower-back-pain-and-performance-enhancement-in-sports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">276</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2267</span> Effect of Core Puncture Diameter on Bio-Char Kiln Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Intagun">W.

Product yields produced from biochar kiln are dependent on process parameters and kiln types used. The objective of this research is to investigate the effect of core puncture diameter on biochar kiln efficiency, i.e., yields of biochar and produced gas. Corncobs were used as raw material to produce biochar. Briquettes from agricultural wastes were used as fuel. Each treatment was performed by changing the core puncture diameter. From the experiment, it is revealed that the yield of biochar at the core puncture diameter of 3.18 mm, 4.76 mm, and 6.35 mm was 10.62 wt. %, 24.12 wt. %, and 12.24 wt. %, of total solid yields, respectively. The yield of produced gas increased with increasing the core puncture diameter. The maximum percentage by weight of the yield of produced gas was 81.53 wt. % which was found at the core puncture diameter of 6.35 mm. The core puncture diameter was furthermore found to affect the temperature distribution inside the kiln and its thermal efficiency. In conclusion, the high efficient biochar kiln can be designed and constructed by using the proper core puncture diameter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anila%20stove" title="anila stove">anila stove</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-char" title=" bio-char"> bio-char</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20conditioning%20materials" title=" soil conditioning materials"> soil conditioning materials</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20distribution" title=" temperature distribution"> temperature distribution</a> </p> <a href="https://publications.waset.org/abstracts/90969/effect-of-core-puncture-diameter-on-bio-char-kiln-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90969.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2266</span> Microstructural Investigations of Metal Oxides Encapsulated Thermochromic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Emirov">Yusuf Emirov</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullatif%20Hakami"> Abdullatif Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20K%20Biswas"> Prasanta K Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20K%20Stefanakos"> Elias K Stefanakos</a>, <a href="https://publications.waset.org/abstracts/search?q=Sesha%20S%20Srinivasan"> Sesha S Srinivasan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is aimed to develop microencapsulated thermochromic materials and the analysis of core-shell formation using high resolution electron microscopy.

The beam consists of two carbon/epoxy composite face sheets, aluminum honeycomb core, and rubber core to enhance the repeated low-velocity impact resistance of sandwich structures. This paper aims to numerically enhance the repeated low-velocity impact resistance of the BHSB via optimizing the aluminum honeycomb core thickness. The beam was investigated employing three core thicknesses: 20 mm, 25 mm, and 30 mm at three impact energy levels (13.5 J, 15.55 J, 21.43 J). The results revealed that increasing the thickness of the aluminum honeycomb core to a certain level enhances the sandwich beam stiffness. The beam with the 25 mm honeycomb core thickness was the only beam that can sustain five repeated impacts achieving the highest impact resistance efficiency index, especially at high energy levels. Furthermore, the bottom face sheet of this beam developed the lowest stresses indicating that this thickness has a relatively better performance during impact events since it allowed minimal stress to reach the bottom face sheet. Overall, increasing the aluminum core thickness will increase the height of its cells subjecting it to buckling phenomenon. Therefore, this study suggests that the optimal thickness of the aluminum honeycomb core should be 65 % of the overall thickness of the sandwich beam to have the best impact resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sandwich%20beams" title="sandwich beams">sandwich beams</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20thickness" title=" core thickness"> core thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20behavior" title=" impact behavior"> impact behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling "> modeling </a> </p> <a href="https://publications.waset.org/abstracts/113735/the-effect-of-honeycomb-core-thickness-on-the-repeated-low-velocity-impact-behavior-of-sandwich-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113735.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2262</span> Synthesis of Nano Iron Copper Core-Shell by Using K-M Reactor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ahmed%20AbdelKawy">Mohamed Ahmed AbdelKawy</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20El-Shazly"> A. H. El-Shazly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, Nano iron-copper core-shell was synthesized by using Kinetic energy micro reactor ( K-M reactor). The reaction between nano-pure iron with copper sulphate pentahydrate (CuSO4.5H2O) beside NaCMC as a stabilizer at K-M reactor gives many advantages in comparison with the traditional chemical method for production of nano iron-Copper core-shell in batch reactor. Many factors were investigated for its effect on the process performance such as initial concentrations of nano iron and copper sulphate pentahydrate solution. Different techniques were used for investigation and characterization of the produced nano iron particles such as SEM, XRD, UV-Vis, XPS, TEM and PSD. The produced Nano iron-copper core-shell particle using micro mixer showed better characteristics than those produced using batch reactor in different aspects such as homogeneity of the produced particles, particle size distribution and size, as core diameter 10nm particle size were obtained. The results showed that 10 nm core diameter were obtained using Micro mixer as compared to 80 nm core diameter in one-fourth the time required by using traditional batch reactor and high thickness of copper shell and good stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20iron" title="nano iron">nano iron</a>, <a href="https://publications.waset.org/abstracts/search?q=core-shell" title=" core-shell"> core-shell</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction%20reaction" title=" reduction reaction"> reduction reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=K-M%20reactor" title=" K-M reactor "> K-M reactor </a> </p> <a href="https://publications.waset.org/abstracts/39924/synthesis-of-nano-iron-copper-core-shell-by-using-k-m-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39924.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2261</span> Paucity of Trauma Literature from a Highly Burdened Developing Country</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Sultan">Rizwan Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasnain%20Zafar"> Hasnain Zafar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trauma is the leading cause of death among young population not only in USA but Pakistan as well. The high prevalence of disease should result in larger amount of data and larger number of publications resulting in exploring room for improvement in the field. We aimed to review trauma literature generated from Pakistan in journals indexed with PubMed from January 2010 to December 2014. Search using term “Trauma AND Pakistan” filtering for relevant dates and species human was done on Pubmed. The abstracts and articles were reviewed by the authors to collect data on a preformed performa. 114 articles were published from Pakistan during these 5 years. 64% articles were published in international journals. 63% articles were published in journals with impact factor less than 1. 54% articles were published from one of the four provinces of Pakistan. 64% of articles provided level 4 while 14% articles provided level 5 evidence on the topic. 55% articles discussed epidemiology in non-representative populations. Trauma literature from Pakistan is not only lacking significantly but is also of poor quality and is unable to offer conclusions on this particular subject. There is a lot of space for improvement in the upcoming years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trauma"
