description: A group is a mathematical object encoding natural notions of symmetries and transformations. Geometric group theory is an area in mathematics devoted to the study of discrete groups by exploring connections between algebraic properties of such groups and topological and geometric properties of spaces on which these groups act. As a distinct area, geometric group theory is relatively new, and became an identifiable branch of mathematics in the early 1990s. Geometric group theory closely interacts with low-dimensional

5/5 4d N = 2 localization

uk: Математика, природничі науки

description: Significant progress has been made in the study of gauge theories in the last decade. Thanks to the discovery of novel techniques and especially supersymmetric localization, the field now possesses a plethora of exact results that previously seemed unreachable. Starting with the work of Nekrasov who computed the instanton partition function for N=2 theories in four dimensions, Pestun computed the exact partition function on a four-sphere for theories with N=2 supersymmetry. Shortly after the partition functions as well as other observables in various spacetime dimensions and compact manifolds were computed. Our school aims in deepening the understanding of current results and at investigating which of our current methods are transferable to theories with less supersymmetry, as well as trying to increase the list of possible observables that are computable via localization. Each week will feature three or four speakers giving one lecture per day. During the first week, in addition to these three one hour and a half lectures there will be discussion and homework sessions in the afternoon. During the second week, some of the lectures will be replaced by talks on more advanced topics.

description: Now and next session: - First up was Euan Adie (Altmetric) who gave us the “10,000 foot view” from Altmetric of the past year. Among the trends he highlighted included academic twitter’s growth year over year and the rise of pre-prints. Another trend perhaps alarming to this audience is that publisher meta-data is getting worse. Without the meta tags, it’s difficult for Altmetric and others to make connections and track mentions. - Following Euan, Heather Piowar and Jason Priem (ImpactStory) who discussed the importance of transparency and open source code, and provided a sneak peak at their new project PaperBuzz, based on CrossRef event and Unpaywall user data. The aim is to help tell you “what’s buzzing this week” by topic or scholarly/non-scholarly audiences, based on open data and code. What are the things people are talking about online and what they’re reading based on open access data. While the sources do not currently provide as much data or data as high in quality, the expectation is that this will continue to change and improve moving forward. - Next up was Daniella Lowenberg (California Digital Library) discussing the “Make Data Count” project. Begun in 2014, this project aims to bring metrics to the data level. Researchers were surveyed about which metrics were most important to them, and based on the survey, the project is now tackling how to best structure data presentation to enable tracking similar to journal articles. The project is in process of producing a draft for posting as a pre-print to get feedback from the community. The project aims to make usage trackage easier and engage researchers across communities, iterating recommendations as they learn from the process. - After Daniella, Polly Allen (Plum Analytics/Elsevier) spoke about Altmetrics and societal impacts – raising attention to issues involved in tracking actual impact (using as an example clinical citations). Polly also made important points regarding the use of big data in general and the biases that are still contained within it, despite the presumption by many that data removes such biases. She encouraged us to fully think through what success means and the societal implications of using any metric, while celebrating the wealth of information that remains to be explored. - Jean Liu (Altmetric) then provided an absolutely adorable narrative about Altmetric for books entitled The Donut’s Quest, detailing the challenges of tracking altmetrics for books. Tracking is surprisingly difficult because there are multiple domains where books live online. Nevertheless, Altmetric has seen an enormous amount of attention paid to books and continue to work to track it. Altmetrics in Research Evaluation session: - First Kate Williams (University of Cambridge) spoke about “Altmetrics in practice: understanding emerging cultures of evaluation,” and her research exploring the social impact of using societal impact metrics. Kate employs sociological and ethnographic analysis to better understand the “space between fields that shapes the culture of evaluation,” and assess impact in a wider context. She discussed how altmetrics and other new forms of evaluative capital can inform development of this framework, but more research is needed around how metrics take meaning in practice. Kate further explained this “space between” involves all stakeholders in the research ecosystem — from scholars to policy makers, publishers, and the public — and :shifting permeable borders to allow techniques to transfer and exist in this hybrid space.” - Next Rebecca Kennison (K|N Consultants) gave an update on the Mellon-funded HuMetricsHSS project, which explores the potential of altmetrics as value-based indicators. The goal is to create a framework addressing “all aspects of scholarly life well-lived,” nurturing values in practice, and empowering scholars to enrich their impact narratives. - The final presentation featured Martin Kirk, PhD, (University of British Columbia) on the current landscape of research evaluation metrics in Canada. Martin reiterated a common theme: current research evaluation conversations are “ALL about impact.” In Canada there is more demand to show definitive results from taxpayer funding, and a highly competitive climate for securing these funds.

description: The Social Side of Altmetrics session chaired by Madeleine Watson from Crossref included 3 talks: - The first talk was presented by Juan Alperin and Katherine Reilly from Simon Fraser University entitled “opportune indicators to narratives: conceptualizing altmetrics for social impact”. Juan criticized altmetrics as a measure of social impact due to lack of proper terminology and definition for something vague that we don’t know what it is exactly. He proposed definition of impact to three main types: epistemic (e.g., new knowledge is created, or someone’s understanding is changed), problem solving (e.g., progress is made towards a problem that needs to be solved), and accountability (e.g., an activity is legitimized). This allows understanding of how different indicators are needed depending on the type of impact being sought, and how the same indicator may mean very different things depending on the impact of interest. Some questions such as: How to analyze societal impact of research using social media? What does it mean in the context of metrics? What do they tell us about behaviours of users? Calling for community to help to narrow down and operationalize the definitions and to be determined about impact and define altmetrics. - The second presentation was on the topic of “Altmetrics for reputation analysis of Brazilian researchers” by Thaiane Oliveria from Federal Fluminese University. Thaiane discussed coverage of Brazilian journals in different citation databases and in Scielo and different policies including altmetrics beside using JCR as for research evaluation pointing out some difficulties and challenges such as Language, political and economic barriers in understanding the dynamics in this ecosystem to be considered before evaluation. - The third presentation entitled “How can we tell a different story? Challenges and opportunities for altmetrics outreach” by Ali Versluis, University of Guelph; Lillian Rigling, University of Western Ontario; Sarah Hare, Indiana University Bloomington. They discussed challenges and opportunities of introducing altmetrics in their university and reflected on some educational, technical, an cultural barriers regarding reactions of their community and how do they value altmetrics as a non-citation based metrics.

Day 2: The Twitter Effect

uk: Комп'ютерні науки

description: - The session started with a presentation from Brett Butliere, who asked: Are more tweeted papers and topics also more contradicted? Brett and his collaborators had conducted a study of over 160,000 tweets about research outputs to determine whether or not research that promoted controversy resulted in more attention – a trend that he noted could potentially be seen in the Altmetric Top 100 lists every year. Amongst the topics most often Tweeted about were things like the dinosaurs and obesity – certainly areas that many people have opinions on. The research team concluded that there was some statistical evidence of their hypothesis, but noted that more research would need to be done and that different methods could also be explored. - Next up was Zohreh Zahedi, who was presenting her research that looks at the imbalanced use of social media across different countries. Zohreh conducted a cross-country analysis of Twitter uses to see whether tweeting about research was ore prevalent in certain countries, and the extent to which people tweeted about authors with affiliations in the same country as the tweeter themselves. Zohreh found some fairly significant differences: although an increasing amount of research comes from China, Russia, South America and India, the majority of twitter activity still takes place in the US and UK, and focuses on research from those countries. She summarized by highlighting that we need to be careful to bear these differences in mid when considering what constitutes ‘high’ vs. ‘low’ amounts of attention, and questioned whether we are in danger of creating an ‘altmetrics divide’. - Fereshteh Didegah then shared some really interesting results from a study which looked at the quality of interactions and engagement around research articles on Twitter. Using 250 articles and their 8,000 associated Tweets, Fereshteh and her team classified engagement into 3 categories: dissemination, consultation and evaluation. The research team also explored issues of false popularity, including harassment and clone accounts, in detail – trying to understand some of the causes behind them and the resulting effect. Overall, the research found that there are a broad array of people involved in discussions about science on Twitter – and that the majority of it focuses on simply sharing rather than adding any meaningful commentary. - ‘Making piracy fun’ became the (perhaps unintended) tag-line of the next talk, where Tim Bowman discussed the results that came from analyzing the use of the #icanhazpdf hashtag. The study aimed to understand what percentage of tweets were requesting documents that were behind a paywall, and what other conversations were taking place around that. By pulling in and matching data from a variety of sources, Tim was able to identify some interesting interactions – including a relatively substantial number of people requesting papers that were in fact already open access. Further digging into the data revealed people using the hashtag to advertise their access to full text content as a service to others, and many librarians seeking to find alternative ways to deliver to the needs of the researchers. Use of the hasthag has become so widespread, Tim noted, that social ‘norms’ have emerged – such as deleting the request Tweet as soon as the paper had been received. These norms provide a ‘frame’ for people to normalize their subversive sharing activity. - Last up was Rodrigo Costas, who has been doing some really exciting work to improve the way we identify scholars on Twitter. Rodrigo matched article records from Web of Science with attention data from Altmetric to identify researcher Twitter accounts (pointing out the limitations of this along the way – there are many researchers on Twitter who have never shared a paper and therefore do not appear in the Altmetric database) and then cross-referencing those accounts with ORCID records to validate the identify of each Tweeter. Rodrigo found over 387,000 scholars with a Twitter account, and was confident of a 94% accuracy amongst those based on the ORCID validation. What makes this research so exciting, Rodrigo posed, is not necessarily what has been done so far but the potential to expand from here: if we are able to better identify researchers in social spaces then we can start to look in more depth at not just how they share papers, but how they communicate and engage on social networks in general, and what that might mean for their field. This was a brilliant session brimming with insights and ideas for further investigation – do get in touch with the authors if you have more to discuss (via Twitter, of course ;))

description: Chair: Catherine Williams, Altmetric: Transparent-by-design: building open infrastructure for the altmetrics community. - First up was Joe Wass, the Principal R&D Engineer at CrossRef, who presented information about the development of a transparent and open data source developed at CrossRef called Crossref Event Data. Joe describes CrossRef and its business of registering content and issuing DOIs. He notes that CrossRef contains approximately 100 million items. What they are trying to create with this new data system is intended to be for everyone; they aren’t creating metrics, just making links. The new data they capture is referred to as an “event” and is coming from outside both Crossref and scholarly publishing; it’s not something easy to track because these event links aren’t consistent, there’s a diverse range of platforms, there is no “publisher” to curate, and there is no structured metadata. In addition, the plethora of event links and contexts are always changing. An “event” is an occasion in which they see a link. They are tracking Reddit, Twitter, Wiki, hypothes.is, wordpress, blogs, and Stack Exchange. This new data source contains artifacts; a snapshot of what they know at the time of capture. They also have evidence records and logs; everything they do at the time of capture, including failures and successes. All the code is open source and all the data is free under CC license; all versions. This allows for reproducibility in research. The bottom line: Crossref will collect this event data, it’s our (as researchers) job to interpret it. - Next up was Jason Priem, from ImpactStory and co-developer of Unpaywall and Buzzpaper, who presented readership data gathered from the use of Unpaywall (http://unpaywall.org/). He started by describing that we are ready for a leap from viewing an online artifact as a static source of information to a period where we can view data from the network involved with the events relating to online artifacts. What got Jason excited about at the beginning of the altmetric movement was discovering how many people are reading a “thing?” Current sources of readership data include PLOS and other publishers, COUNTER, special arrangement with publishers (MESUR), Mendeley (by proxy), and CrossRef DOI resolutions. Unpaywall, a browser extension that is free, open source, web extension to help people find legal, open access copies of scholarship, now enters the picture. Unpaywall is powered by oaDOI; oaDOI is a database of 90M papers with DOIs and links to OA version of ~15M papers. oaDOI API handles between 500k and 2M requests per day. Unpaywall has 100k+ active users from 100+ countries, has captured 4.6M total events, is seeing 80k new usage events per day, and has tracked 2M DOIs with an event. Unpaywall can track events, not just counts; it offers fine time granularity and IP-derived categorizations (such as geo location). Jason presented Unpaywall data and compared it with tweets, as described by audience; to do this, Unpaywall data can be viewed by IP and tell if readers are on university campus in order to compare university readers versus those outside of the university. The data also provides researchers with the ability to look at country, network of co-readership, article recommendations, and prediction. - Lastly, Kornelia Junge, who is the Senior Research Manager at Wiley, presented information on navigating the space between open science and business intelligence. Kornelia started by arguing that all research isn’t being captured by altmetrics. Kornelia then went on to state that corporations don’t publish articles, they publish patents; she called for us to pay closer attention to these corporate researchers. She found that authors who published throughout 8-year period had an average of 1 article per year. Output from academics who started in 2013, is less than 1 article per 2 years. When examining corporate research, she argued that authors don’t necessarily publish standalone articles, instead they may publish a report, patent, clinical trial, white paper, annotated dataset, or email. Some of these take more work than an article, others less. She then went on to examine how many pieces of information exist worldwide for corporate researchers? The problem with finding this answer is that corporate researchers don’t share the data. So instead, she focused on how many researchers exist? Data from UNESCO Institute of Statistics revealed that researcher counts (Headcounts) cover 148 countries; researcher counts by country (FTE) was 130; UNESCO presented data by sector also; this included business, higher education, government, and private nonprofit. This dataset represents 97% of world population. She found that the majority of researchers work in industry, followed by academia. Kornelia estimated that there are over 9 million researchers, with more than half of them working in corporate environments. She then looked at what we know about this large population and argued that corporate research must make a difference for the business, that they need to minimize time-effort to produce results, and that there was a difference between the types of tools available to corporate researchers in large and small companies. In addition, these researchers cannot trust unknown sources when performing research. In this corporate world, she argued that researchers are limited by nondisclosure agreements, no independent peer review, and have no insight into competitor research. The quality of output might suffer because of this. She argued that corporate research can be more transparent and would be benefit for companies and society. They should be encouraged to publish more in peer-reviewed journals and work as reviewers and editorial board members. In addition, corporations should sponsor research information infrastructure for society. This was a great session and involved some very interesting new tools and data sets, which are being made available to the research community. In addition, Kornelia’s presentation on corporate researchers sheds a spotlight on a vast community of scientists who remain relatively unknown.

description: - William Gunn, Mendeley – Understanding reader intent: Who are the readers of a papers on Mendeley and why do they add what they add to their libraries? With an open catalog of millions of papers and applications used by millions of researchers to organize, share, and discover research, Mendeley is one of the most comprehensive sources of altmetrics available. However, there’s a lot that still isn’t known about the underlying population from which the metrics are derived, and the various behaviors that they engage in as they build their Mendeley library. We are collecting the largest sample of Mendeley reader behavior and will make the survey data available to the altmetrics community. In this talk, we will describe the data collection, as well as present some of the highlights of the data so far. - David Walters, Brunel University – Institutional services and altmetrics as drivers for a cultural transition to open scholarship The causal effect to the impact of scholarly outputs disseminated under an open model may be mirrored in the statistical analysis provided by Altmetrics. In the wake of technological developments and funder expectations, we at Brunel University London have a longstanding commitment for open access to our research outputs, going back over ten years. A single campus, community focused institution, our services and systems been tailored to support our scholars and effect cultural change during the transition toward open scholarship. I will talk about how the evolution of our systems deployment has led to a support network that facilitates University publishing for new, open forms of scholarly output and that enables the monitoring of traditional published outputs through green, gold or paywall distribution models. Our publishing systems include an Institutional Repository (IR) and FigShare Data Repository. Our Current Research Information System (CRIS) provides the mechanism to monitor publication trends across our entire portfolio. With the monitoring of open academic activity fully supported by the CRIS along with partner services Cottage Labs, DOAJ, Sherpa and Core, I will outline how we developed a small centralised service around these tools tailored to foster engagement and to transform dissemination practice across our community. Alongside the proliferation of social tools for researchers has been the growth of alternative metrics. From our services at ground level we are well positioned to comment on the divide that exists between those researchers who actively use their social media networks to promote the discovery of their output and those who don’t. I will discuss our ‘Altmetric for Institutions’ setup, which monitors the records held in our CRIS. I will demonstrate how this information is shared with authors, research managers and marketing to benefit different areas of institution, but in particular how this provides a powerful visual prompt to users of our service who may be unsure about the academic return of the open movements in real terms. We are beginning to see how the data we work with every day could be used to extend the discovery of our academics work and to promote the institutions reputation in this space. We curate a huge range of high quality metadata within our CRIS; keywords, subjects and themes to name but a few. We want to see better ways of using this data to select and promote our publications across the social sphere – ideally making use of and developing our existing local networks and the networks of our researchers, and I will speak to our progress in this area so far. I will conclude by arguing that the clear, mutualistic relationship between the altmetrics and open science movements necessitates effective co-operation with local university services to bring about a smooth and swift transition for authors to the open scholarly model. - Kim Holmberg, University of Turku, Finland – Measuring the societal impact of open science Altmetrics, which refers to both the research field and the altmetric events being investigated, has the potential to provide a more nuanced understanding of where and how research has had an impact. For instance, while citations only reflect scientific impact, tweets, blog citations, Facebook likes, and so on may be able to reflect other types of impact such as societal impact on various audiences. Altmetrics is also closely connected to the Open Science movement, as both have emerged from the transition of scholarly communication to the web. In addition, while the open science movement still lacks incentives for individual researchers to adopt some of the ideologies of the movement, which in turn hinders the rapid assimilation of it, altmetrics provides novel indicators for attention, visibility, and impact that could stimulate the interest of researchers. As researchers see how their work is gaining attention online, it might motivate them to share more of their work openly. Our study will present preliminary results from a new research project (financed by the Ministry of Education in Finland) that works at the intersection of altmetrics and open science. The project investigates the connection between altmetrics and open science, maps the current state of research in Finland using altmetric research methods and data, and develops new indicators to measure societal impact and new methods to study these phenomena. Our preliminary results on the connection between altmetrics and open access publications show a significant difference between altmetric indicators based on number of mentions of open access publications in their content. Open access articles receive more attention on Facebook and (especially) on Twitter compared to articles that are behind paywalls. The opposite appears to be the case for Mendeley readers and (to some extent) for Wikipedia posts, as open access articles are not used as much as those that are behind paywalls in these contexts. The preliminary results are based on an analysis of how almost 4 million altmetric events are spread between articles in open access journals (as listed by DOAJ) and other journals. The results support the assumption that Twitter especially might be able to reflect the attention of a wider public, while Mendeley is used mainly by researchers. In addition, the preliminary results also suggest that a great deal of the Wikipedia articles are in fact written by researchers with paid access to research articles, providing additional evidence of the high quality of Wikipedia articles.

Altmetrics and publishers

uk: Комп'ютерні науки

description: - Timo Hannay of Digital Science opened the session a with a brief introduction. He pointed out that the metrics related to only journals highlight only one dimension of the impact. Futhermore the metrics related to the article level are “much more than metrics”. - After introducing himself Hans Zijistra illustrated the work done by Elsevier in the field of altmetrics. His presentation was very interesting for me: he spoke of passion and enthusiasm, to bring to bridge the communication gaps between old and new researchers about the issue of alternative metrics. For him Altmetrics are: “another angle of paper not the only way to impact”. This is a very important aspect in those who, like me, are trying to introduce the existence of altmetrics in their institutions. Hans points out how often the term Altmetrics “confuses people”. He suggested to promote, educate, explore these metrics and make them known to scientists with a “holistic approach”. But, in the meantime, what do Elsevier do? They have been running a pilot across Scopus and ScienceDirect in which they are testing different versions of the Altmetric donut, and soon will be announcing further developments soon. At the end of his presentation, Hans has highlighted the importance of quality over quantity, and than when you click the donut to reveal the full original data, Almetrics becomes “more sexy”! - Jennifer Lin brought the experience of open access publishers. PLOS was the first publisher that introduced article level metrics for their journals. She started her presentation with an Albert Einstein citation: “Not everything that can be counted counts, and not everything that counts can be counted”. Jennifer revealed how to construct such a system of metrics is very difficult. Researchers want to find the relevant papers, the most bookmarked, and navigate through the literature. In the other words, what happens behind the numbers and the data, is altmetrics. PLOS is focusing on the article usage by subject area and the use across all the materials. The future development of the Article Level Metrics,-ALM- for PLOS will be to tell the “stories behind the articles, and stories across article features”. - Martijn Roelandse talked about the Springer and BioMed Central experience. He started with an important question: which counts more: an article with 0 citation but published in a top ten journal, or an article published in lower-impact factor journal but with many citations? In the same way, is more important if an article has many citations, or an article with a lot of downloads? Hard to answer! Springer has compiled a list of the top article downloads for 2013 – what they found was that the most downloaded articles belong to journals without Impact Factors. What Martijn proposed about the idea of the evolution of metrics was interesting: beginning with article level metric, passing by journal metric, until finally reaching person level metric. In another words, a different way to look at the scientific community. - Last but not least, Ian Mulvany gave the eLife perspective. Firstly, he spoke about the project and the mission that characterizes eLife. Secondly he explained the platform and the work done. A very important aspect was the platform host and the bugs that complicated the visualization of the portal making it “a black box” without data. But don’t worry: they have changed their platform host and now e-life is running with a new version of LAGOTTO platform (on the basis of PLOS ALM). In this way they have solved the problem of black box and provide usage data. In the future e-Life-aims to have its own local repository of data and with a project call DET they will be able to provide own metrics. For years the aim of the Publisher was to maximize the impact factor of their journals. The revolution continues! It will be interesting to observe how publishers adopt alternative metrics to encourage the growth of science and knowledge.

Altmetrics & Research Evaluation

uk: Комп'ютерні науки

description: Chair: Erik van Aert, NWO - Thed van Leeuwen, Rodrigo Costas, & Clifford Tatum (CWTS – Leiden University) – Slowing the pace on applying metric techniques on Open Science: Traditionally, advanced bibliometrics have been the ‘gold standard’ in research evaluations in many fields. Due to changes in communication patterns in various fields, we now see alternative ways of assessing research appearing on the landscape. One of the major developments in scientific communication patterns is the advent of the Openness movement, through which various activities in academic life become more democratic, transparent, and hopefully fairer. This stretches out to publishing and the costs involved, how data are shared, and how peer review is organized, to name some instances in which the issue of Openness is raised. Of a somewhat more recent nature is the way assessment of scholarly activity is organized, in particular with respect to the way the various audiences with whom scholars are communicating are considered. A new way of looking at research assessment is through the recent ‘alternative metrics’ or also referred to as Altmetrics. More classical bibliometrics are under pressure, due to international (DORA-Declaration) and national debates and initiatives (SiT) related to the organization of research assessment in various layers of the science system. This stirs a re-focus from science policy towards alternative ways to assess research performance. In this presentation we will show, by a recent example, how careful we have to be in making choices for metrics in order to support research assessment practices as well as science policy decision making. - Eppo Bruins & Rens Vandeberg (STW / NWO) – Innovation indicators: Why the future is so hard to predict: In science and innovation, quality indicators are usually based on counting uniform and globally applicable parameters. Whereas this completely ignores the pluriform character of reality, any differentiated and more nuanced approach has usually led to a zoo of deliverables, hampering comparison and serious evaluation of actions. We present an impact-driven approach, the 4D-model for valorisation, which overcomes these shortcomings and which helps to get the ‘real talk on the table’. We also present the first application of this approach for the evaluation of innovation programs and funding instruments. - Edwin Horlings, Rathenau Institute – The power and appeal of new metrics: can we use Altmetrics for evaluation in science? With the rise of the information society, science has moved into a global online environment, which has spawned new forms of communication, new channels and a cultural shift towards openness. Online communications produce new metrics that can be harvested, aggregated, and compared with other, existing metrics. Altmetrics have enriched and diversified our data on science and provide alternatives to measuring scholarly and societal impact. As a data source for science, Altmetrics can already be used and there are countless examples of good empirical studies. But for Altmetrics indicators to be used in formal evaluations, the quality standards must go up. I first discuss the main properties of indicators for formal evaluations. Are Altmetrics indicators reliable and unbiased, are they valid, can we scale from individuals to groups to institutes to nations and can we compare them? We should also understand the behavioural mechanisms that produce these metrics. I believe that at the moment Altmetrics is not suitable for use in formal evaluations. However, in the late 1950s the same was true for the citation indexes that have become the foundation of evaluative bibliometrics. I explore what needs to be done by looking at efforts to introduce a wider set of metrics for general well-being as a supplement to Gross Domestic Product. I end with a reflection.The spirit of Altmetrics is revolutionary: look beyond conventional indicators and think more broadly about impact and involvement. In that same spirit, you might consider not using Altmetrics in evaluation: being able to measure everything does not make you happier or more intelligent. Or you might consider broadening the scope of Altmetrics to include all the functions of university simultaneously: education, research, and valorisation. - Peter van den Besselaar (VU University Amsterdam) – What is altmetrics and how to proceed with it? Bibliometrics was driven by availability of data: Web of Science, and the data enabled but also limited the kind of indicators for scholarly performance. Most indicators are variants of publication and citation counts, and have as we know many limitations. Altmetrics follows to some extent a similar development. New data are deployed to develop new indicators. However, I will argue that one needs to understand the dynamics of the science system in order to develop adequate indicators. In this presentation I will first discuss the limits of publication and citation counts, as well as of peer review. Then I discus a few examples of Altmetrics: Indicator for societal impact of research-infrastructures, indicators for independence of researchers, and indicators for the performance of research groups. What can we learn from these examples? The issue is not to replace not so good indicators by peer review as is increasingly argued, but to develop theory based smart Altmetrics to support selection and decision-making. The examples may show how that can work.

description: - Josh Borrow (Durham University) & Pedro Russo (Leiden Observatory) – A Blueprint for Assessing Societal Impact Through Public Engagement: Societal impact of research outputs are difficult to measure. Over the past few decades, there has been a huge increase in the amount of public engagement performed by researchers. These initiatives are generally poorly assessed, with abstract searches for learning impact rather than focusing on development of technique. The assessments that are being implemented tend to be motivated by funding bodies’ quest for ‘societal impact’ and require a focus on abstract metrics that are generally irrelevant and difficult to measure. In this presentation, we describe a new method for assessing public engagement events in research. This evaluation framework, as well as supporting researchers in public engagement, will lead to meaningful appraisals of initiatives such that researchers can receive career development for their work. All of this will lead to a greater respect for public engagement within research institutions, fighting the anti-engagement atmosphere and promoting young researchers to engage with the public and have a impact on society. - Robin Haunschild, Max Planck Institute for Solid State Research – Networks of reader and country status: An analysis of Mendeley reader statistics: Mendeley is one of the most important sources for altmetrics (Bornmann, 2014). Here, bookmarks of papers in this popular online reference manager are counted which can be expected to reflect readership of publications. Since Mendeley does not only provide straight reader counts, but also itemized counts for different reader groups, the data can be used for sophisticated analyses. In order to reveal the structure of complex data, social network analysis provides the most suitable methods (de Nooy, Mrvar, & Batagelj, 2011). In this study, we analyze Mendeley readership data of a set of 1,133,224 articles and 64,960 reviews with publication year 2012. In total, we found 9,352,424 reader counts for articles (8.25 reader counts per article on average) and 1,335,764 reader counts for reviews (20.56 reader counts for reviews on average). The Mendeley reader count information was gathered by requests to the Mendeley API. The academic status of the users was available in all cases, the sub-discipline information was available in nearly all cases, but the country information was available only for 49.3% of the articles and 66.1% of the reviews. In total, we observed 1,572,240 reader counts (16.8%) for articles and 212,693 reader counts (15.9%) for reviews where the location information was shared. Three respective networks were generated and groups were distinguished using the community-finding algorithm of Blondel, Guillaume, Lambiotte, and Lefebvre (2008): (1) The network based on disciplinary affiliations of Mendeley readers contains four groups: (i) biology, (ii) social science and humanities (including relevant computer science), (iii) bio-medical sciences, and (iv) natural science and engineering. In all four groups, the category with the addition “miscellaneous” prevails. (2) The network of co-readers in terms of professional status shows that a common interest in papers is mainly shared among PhD students, Master’s students, and postdocs. (3) The country network focusses on global readership patterns: a group of 53 nations is identified as core to the scientific enterprise, including most OECD countries, Russia, and China. - Sünje Dallmeier-Tiessen (CERN) & Merce Crosas (Harvard University) – Comprehensive tracking of research workflows using Altmetrics in Social Sciences and High-Energy Physics: Altmetrics are becoming increasingly pervasive for traditional scholarly objects. However, Open Science and scholarly communication move beyond the sharing of “only” articles and data, but also include code, models, documentations, visualizations etc.. For future reinterpretation, reuse or reproducibility of research results it is indispensable to preserve these scholarly elements to make them accessible and retrievable in the long term. The products that should be considered result from research workflows through the lifetime of (ongoing) experiments or projects and, thus, the objects might be subject to change over time while they should be referenceable for others. Using altmetrics as a tool to track and visualize the use or impact of such materials could provide an important incentive to researchers (and service providers) to engage in this new realm of preservation and publishing activities. However, it is needed to understand how to expand the altmetrics concept to apply to non traditional objects and their preservation and publishing challenges. This presentation highlights two examples from two very different communities, the Social Sciences and High-Energy Physics. At Harvard’s Institute for Quantitative Social Sciences and at CERN preservation and Open Science tools are being built and are (partially) already in use for both communities. We present a comparative study of the different communities, their research processes and how this impacts the resulting scholarly outputs. We will highlight the different needs in terms of preservation and Open Science and underline how this impacts the need, potential use and exposure of altmetrics – for data and other non traditional research outputs. Certainly, there are commonalities between the disciplines and their services, e.g. when using standards or emerging concepts to support data citation. However, when supporting the research workflows more comprehensively, one touches specific challenges like sensitive data or dynamic data which both demand specific solutions. In the presentation we will investigate how this (might) impacts usage and statistics (or not). - Martijn Roelandse, Springer – Bookmetrix: Developed in partnership between Springer and Altmetric, Bookmetrix is the first platform of its kind to offer integrated traditional and non-traditional metrics for books and chapters. Designed to give authors, editors and readers easy access to this combined data all in one place for the first time, Bookmetrix helps to set a new standard for monitoring and reporting the activity surrounding a book post publication. During my talk I will take you on a journey, from inception to launch and beyond.

description: Lectures 1-3 are mostly based on our recent work with Linhui Shen. Given a surface S with punctures and special points on the boundary considered modulo isotopy, and a split semi-simple adjoint group G, we define and quantize moduli spaces Loc(G,S) G-local systems on S, generalising character varieties. To achieve this, we introduce a new moduli space P(G, S) closely related to Loc(G,S). We prove that it has a cluster Poisson variety structure, equivariant under the action of a discrete group, containing the mapping class group of S. This generalises results of V. Fock and the author, and I. Le. For any cluster Poisson variety X, we consider the quantum Langlands modular double of the algebra of regular functions on X. If the Planck constant h is either real or unitary, we equip it with a structure of a *-algebra, and construct its principal series of representations. Combining this, we get principal series representations of the quantum Langlands modular double of the algebras of regular functions on moduli spaces P(G, S) and Loc(G,S). We discuss applications to representations theory, geometry, and mathematical physics. In particular, when S has no boundary, we get a local system of infinite dimensional vector spaces over the punctured determinant line bundle on the moduli space M(g,n). Assigning to a complex structure on S the coinvariants of oscillatory representations of W-algebras sitting at the punctures of S, we get another local system on the same spa. We conjecture there exists a natural non-degenerate pairing between these local systems, providing conformal blocks for Liouville / Toda theories. In Lecture 4 we discuss spectral description of non-commutative local systems on S, providing a non-commutative cluster structure of the latter. It is based on our joint work with Maxim Kontsevich.

3/4 Inviscid Limit and Prandtl System

uk: Математика, природничі науки

description: One of the main open problems in the mathematical analysis of fluid flows is the understanding of the inviscid limit in the presence of boundaries. In the case of a fixed bounded domain, it is an open problem to know whether solutions to the Navier-Stokes system with no slip boundary condition (zero Dirichlet boundary condition) do converge to a solution to the Euler system when the viscosity goes to zero. The main problem here comes from the fact that we cannot impose a no slip boundary condition for the Euler system. To recover a zero Dirichlet condition, Prandtl proposed to introduce a boundary layer (a small neighborhood of the boundary) in which viscous effects are still present. It turns out that the system that governs the flow in this small neighborhood, namely the Prandtl system has many mathematical difficulties. The goal of this course is to discuss some of the recent development in the inviscid limit as well as the study of the Prandtl system. We will also discuss the singularity formation for both the stationary and non stationary Prandtl system.

description: Bridgeland stability structure/condition on a triangulated category is a vast generalization of the notion of an ample line bunlde (or polarization) in algebraic geometry. The origin of the notion lies in string theory, and is applicable to derived categories of coherent sheaves, quiver representations and Fukaya categories. In a category with Bridgeland stability every objects carries a canonical filtration with semi-stable pieces, an analog of Harder-Narasimhan filtration. It is expected that for categories over complex numbers Bridgeland stability structures often admit analytic enhancements, similar to the relation between ample bundles and usual Kaehler metrics. In a sense, this should be a generalization Donaldson-Uhlenbeck-Yau theorem which syas that a holomorphic vector bundle over compact Kaehler manifold is polystable if and only if it admits a metrization satisfying hermitean Yang-Mills equation. In my course I will talk about a non-archimedean analog of analytic Bridgeland stability. I will show several examples, results and conjectures. In particular, I'll introduce non-archimedean moment map equations, generalized honeycomb diagrams, and hypothetical stability on derived categories of coherent sheaves on maximally degenerating varieties over non-archimedean fields.

description: Flows on surfaces are one of the fundamental examples of dynamical systems, studied since Poincaré; area preserving flows arise from many physical and mathematical examples, such as the Novikov model of electrons in a metal, unfolding of billiards in polygons, pseudo-periodic topology. In this course we will focus on smooth area-preserving -or locally Hamiltonian- flows and their ergodic properties. The course will be self-contained, so we will define basic ergodic theory notions as needed and no prior background in the area will be assumed. The course aim is to explain some of the many developments happened in the last decade. These include the full classification of generic mixing properties (mixing, weak mixing, absence of mixing) motivated by a conjecture by Arnold, up to very recent rigidity and disjointness results, which are based on a breakthrough adaptation of ideas originated from Marina Ratner's work on unipotent flows to the context of flows with singularities. We will in particular highlight the role played by shearing as a key geometric mechanism which explains many of the chaotic properties in this setup. A key tool is provided by Diophantine conditions, which, in the context of higher genus surfaces, are imposed through a multi-dimensional continued fraction algorithm (Rauzy-Veech induction): we will explain how and why they appear and how they allow to prove quantitative shearing estimates needed to investigate chaotic properties.

description: Geometry of scalar curvature, that is comparable in scope to symplectic geometry, mediates between two worlds: the domain of rigidity, one sees in convexity and the realm of softness, characteristic of topology, such as the cobordism theory. The aim of this course is threefold: 1. An overview of old and new results, mostly, but not exclusively, on the rigidity side, of manifolds X with positive and, more generally, bounded from below scalar curvatures Sc(X), along with a brief introduction to main techniques. 2. Proof of new geometric comparison type inequalities for Riemannian manifolds X with lower bounds on Sc(X) and on mean curvatures of the boundaries of X. 3. Discussion of open problems concerning Sc superior at 0.
