Joining the ‘buzz’ : the role of social media in raising research visibilityEileen Shepherd
Traditional bibliometric methods of evaluating academic research, such as journal impact factors and article citations, have been supplemented in the past 5-10 years by the development of altmetrics (alternative metrics or article level metrics). Altmetrics measures impact of research, data and publications, such as references in data and knowledge bases, article views, downloads and mentions in social media and news media. This presentation gives a brief background to altmetrics and demonstrates how Rhodes University librarians are using social media to raise the visibility of the research output of their institution. (Rhodes University is in Grahamstown, South Africa)
This presentation is about Scholarly Communications and how it works, what are ways through one can identify right journals for publications and also briefly discusses preprints as an alternative publications space for making the research more open and visible.
I apply Ranganathan's 5 laws of library science to altmetrics, as part of a holistic research impact support service. I discuss what altmetrics are, what they measure, their uses throughout the research lifecycle, and where you can get them. I then apply Ranganathan's 4th law, saving the time of the user, to the harvesting of altmetrics by research information systems, embedding them at the point of need. The challenge of altmetrics is to change our concept of what an institutional repository is, from a simple container of research outputs to a smart system that harvests and catalogs a much broader range of output and impact data elements.

This presentations reports on a systematic and comprehensive comparison of the coverage of the three major bibliometric databases: Google Scholar, Scopus and the Web of Science. Based on a sample of 146 senior academics in five broad disciplinary areas, we therefore provide both a longitudinal and a cross-disciplinary comparison of the three databases.
Our longitudinal comparison of eight data points between 2013 and 2015 shows a consistent and reasonably stable quarterly growth for both publications and citations across the three databases. This suggests that all three databases provide sufficient stability of coverage to be used for more detailed cross-disciplinary comparisons.
Our cross-disciplinary comparison of the three databases includes four key research metrics (publications, citations, h-index, and hI,annual, an annualised individual h-index) and five major disciplines (Humanities, Social Sciences, Engineering, Sciences and Life Sciences). We show that both the data source and the specific metrics used change the conclusions that can be drawn from cross-disciplinary comparisons.

Why Research Libraries supporting Open Access is vital to the achievement of ...ldore1
The International Federation of Library Associations and Institutions (IFLA) supports the Lyon Declaration on Access to Information and Development, 2014 (which was a response/commitment to promote meaningful access to information as part of the United Nations Sustainable Development Goals), which states that a right to information worldwide would be transformational. Access to information supports development by empowering people, especially marginalised people and those living in poverty.
In this talk there will be a discussion of the vital importance of the availability of Open Access research publications to improve access to information and knowledge to enable the fulfilment of the SDGs to end poverty, improve health and education, reduce inequality, encourage economic growth, and tackle environmental destruction and climate change.
There will also be discussion of the role Libraries have to play in supporting Open Access at a national and local level, the options for publishing Open Access and the challenges.
Finally, the tools available to measure what proportion of your institutions papers are available as Open Access and what proportion are covering SDG topics will be demonstrated. These Tools will include Scopus, Web of Science, Google Scholar and Altmetrics Explorer.

Les médias sociaux et leur introduction dans un contexte académique ont généré de nouvelles opportunités pour les chercheurs de diffuser leur recherche plus rapidement et à une audience plus grande. Twitter, Facebook, ainsi que les plateformes spécialisées comme ResearchGate et Academia.edu, offrent plusieurs possibilités aux chercheurs d’augmenter leur visibilité et celle de leur recherche. Ces plateformes constituent aussi certains défis pour les chercheurs : leur multiplication fait en sorte qu’ils peuvent s’y perdre et entraîner des pertes de temps. Dans certains cas extrêmes, des commentaires inappropriés émis par les chercheurs sur les médias sociaux ont même mené à des licenciements.
Dans un contexte où l’évaluation de la recherche prend une place de plus en plus importante, les activités associées aux contenus savants partagés sur les médias sociaux ont été proposées par certains comme étant des indicateurs de l’impact de ces contenus. Ces indicateurs, appelés «altmetrics» incluent, par exemple, le nombre de tweets, de liens Facebook, de lecteurs sur Mendeley, de mentions dans les blogs, d’évaluations d’experts sur F1000, de vues sur figshare ainsi que de nombreux autres événements en ligne qui se réfèrent aux documents ou acteurs scientifiques. L’idée derrière les altmetrics était de rendre l’évaluation de la recherche plus englobante, d’aller au-delà du nombre de publications et de citations, afin de capturer l’impact social sur le grand public. Ce lien entre médias sociaux et impact social demeure toutefois à prouver.
Cette formation fournira un aperçu des résultats de recherche récents sur les altmetrics et donnera quelques conseils sur l’utilisation professionnelle des médias sociaux dans un contexte académique.

Background:
‘Altmetrics’ have been introduced as a way to capture scientific output and impact beyond papers and citations based on traces on various social media platforms (Priem, Taraborelli, Groth, & Neylon, 2010), of which Twitter is believed to have a particular potential to reflect societal impact of research. The analysis and application of various altmetrics such as tweets to scientific papers, however, still lack adequate interpretative frameworks mainly because the processes behind the metrics are not yet fully understood. Currently each tweet is counted equally on platforms such as Altmetric.com or ImpactStory and studies tend to ignore user type and tweet content, although tweets have been shown to range from serious discussions to humour and self-promotion to automated mentions (Haustein et al., 2015).
Objective:
Communities of attention around scientific publications on Twitter are identified based on engagement and exposure of users. Engagement is measured as the degree to which the tweet text differs from the title of the tweeted paper. Exposure refers to the potential audience of the tweet as measured by the number of the user’s followers.
Methods:
Publications from 2012 covered by Web of Science were matched to tweets (until June 2014, excluding retweets) recorded by Altmetric.com via DOI resulting in 660,149 tweets, 237,222 tweeted papers, and 125,083 Twitter users. Engagement was calculated based on the dissimilarity between the tweet text (excluding user names and URLs) and the title of the tweeted document. User data (including the number of followers representing exposure) was collected from Altmetric.com and the Twitter API.
Four user categories were defined, classifying users into four quadrants A, B, C and D according to engagement and exposure values above and below the median of the whole dataset (Figure 1). Statistics based on the tweeting behaviour of users were calculated for each of the categories. The connections between 708 users with more than 100 publications based on co-mentions of the same papers were visualized in a network graph in Figure 1.
Results:
Users in the four categories differ according to tweeting behavior (Figure 1). Users in A have the highest mean tweets per day (based on all tweets) and those in D tweet more about scientific papers (typical for bots identified by Haustein et al. (2015)), while users in A and B discuss publications with slightly higher relative citation rates.

Haustein, S., Bowman, T.D. & Costas, R. (2015). When is an article actually published? An analysis of online availability, publication, and indexation dates
Abstract. With the acceleration of scholarly communication in the digital era, the publication year is no longer a sufficient level of time aggregation for bibliometric and social media indicators. Papers are increasingly cited before they have been officially published in a journal issue and mentioned on Twitter within days of online availability. In order to find a suitable proxy for the day of online publication allowing for the computation of more accurate benchmarks and fine-grained citation and social media event windows, various dates are compared for a set of 58,896 papers published by Nature Publishing Group, PLOS, Springer and Wiley-Blackwell in 2012. Dates include the online date provided by the publishers, the month of the journal issue, the Web of Science indexing date, the date of the first tweet mentioning the paper as well as the Altmetric.com publication and first-seen dates. Comparing these dates, the analysis reveals that large differences exist between publishers, leading to the conclusion that more transparency and standardization is needed in the reporting of publication dates. The date on which the fixed journal article (Version of Record) is first made available on the publisher's website is proposed as a consistent definition of the online date.
Altmetrics: opportunités et défis associés à l’usage des médias sociaux dans ...Stefanie Haustein
350 ans après sa création, la revue savante demeure le principal moyen de diffusion des connaissances savantes, et les citations reçues par les articles constituent la mesure principale de leur impact scientifique. Les médias sociaux et leur introduction dans un contexte académique ont généré de nouvelles opportunités pour capturer l’impact sur un public potentiellement plus large—pas simplement les auteurs qui citent—et plus rapide, compte tenu de la vitesse avec laquelle l’activité dans les médias sociaux peut être mesurée. Le nombre de tweets, de publications Facebook, de lecteurs sur Mendeley, d’évaluations d’experts sur F1000, et de vues sur Slideshare sont des exemples d’indicateurs considérés comme des «altmetrics». De nombreuses revues fournissent également les «altmetrics» associées à chacun de leurs articles, certains chercheurs les présentent sur leurs CVs, et certains organismes subventionnaires commencent à envisager leur utilisation. Même s’il est devenu évident que ces nouvelles mesures sont très hétérogènes et ne peuvent remplacer les citations, on sait encore peu de choses sur leur signification et le type d’impact qu’ils reflètent. Cette communication fera un tour d’horizon des opportunités et des défis associés à l’utilisation de médias sociaux dans la communication savante.

Keynote at ISI2015 in Zadar, Croatia

Abstract. Since its creation 350 years ago, the scientific peer-reviewed journal has become the central and most important form of scholarly communication in the natural sciences and medicine. Although the digital revolution has facilitated and accelerated the publishing process by moving from print to online, it has not changed the scientific journal and scholarly communication as such. Today publications and citations in peer-reviewed journals are considered as indicators of scientific productivity and impact and used and misused in research evaluation. As scholarly communication is becoming more open and diverse and manuscripts, data, presentations and code are shared online, the altmetrics and open science movement demand the adaption of evaluation practices. Parallels are drawn between the early days of bibliometrics and current altmetrics research highlighting possibilities and limitations of various metrics and warning against adverse effects.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

3. Background: Global Health
• Global health research (GHR) defined as:
• ”an area for study, research, and practice that places a
priority on improving health and achieving equity in health
for all people worldwide" (Koplan et al., 2009, p. 1995)
• “a multi- and interdisciplinary field concerned with
improving health and achieving equity in health for all
people.” (MeSH, 2015)
• Knowledge sharing is central in GHR
• Access to publications essential for researchers and
practitioners in LMICs

Gold OA journal (non-APC): Open access journal which provides immediate access to all of their content free of charge to both readers and authors. Many of these journals were often financed or subsidized by scientific societies or associations.
Gold OA journal (APC): Open access journal which provides free immediate access to all of their contents based on an author-pays model via APCs. APCs were collected in or converted to USD.
Delayed OA journal: Subscription journal which provides all content for free after an embargo or delay period of several months to years. Journals which provide delayed open access to only some of their content were classified as subscription journals and their free papers identified as delayed OA articles.
Hybrid journal: Subscription journal which is primarily financed by reader-pays model based on subscriptions and pay-per-view fees but allows authors to pay an APC to make their article available free of charge for the reader without delay. APCs were collected in or converted to USD.
Subscription only journal: Subscription journal which is financed by reader-pays model based on subscriptions and pay-per-view fees and does not offer author-pays OA options. Some subscription journals might decide to make single articles available for free temporarily or permanently to promote certain contents. If identified by PubMed, these free articles are coded as “other free access”.
Unknown: Journals for which the access status could not be determined.
If APCs were not provided in USD, currencies were converted using the mean of weekly historical conversion rates between 01.01.2010 and 31.12.2014 using OANDA (http://www.oanda.com/currency/historical-rates).
