The document discusses the growing interest in altmetrics for measuring the impact of scholarly research. It provides an overview of various altmetric data aggregators and tools, such as Altmetric.com, Plum Analytics, Impact Story, and Crossref's DOI Event Tracker. The document also examines issues with altmetrics, such as concerns about the reliability, quality, and consistency of altmetric data.
This document discusses transparency issues with current metrics used to measure scientific impact, such as PageRank and Journal Impact Factor. It argues that these metrics lack transparency in their algorithms and are susceptible to gaming. As an alternative, it proposes altmetrics, which provide transparent, verifiable impact indicators linked to open data sources. Altmetrics track references and reuse of scholarly works both within and outside of academia. They aim to give a more comprehensive view of impact by measuring extra-academic usage and reuse of open scholarly content. The document calls for more transparent APIs and measures of reuse to better capture scientific impact.

Insights into Influence: Scholar-Practitioner Profile in the Academy and Comm...Kathleen Reed
Demonstrating knowledge mobilization and accountability are increasingly prominent features of the scholarly landscape; scholar-practitioners need to understand and strategically manage available indicators of impact. At the same time, traditional scholarly metrics and indexing are converging with social media, resulting in new approaches for measuring scholar-practitioner influence. The emerging scene challenges libraries to support scholars, practitioners and students to engage with an evolving environment in which much may be gained or forfeited depending on how reputation is curated. For librarians to assist scholars in this new altmetrics environment, more needs to be known about how students and faculty are or are not engaging with emerging tools available to them. This presentation gives an overview of the considerations, perceptions, and issues related to the use of altmetrics by graduate students and scholar-practitioners at VIU and Royal Roads University.

Microsoft: A Waking Giant In Healthcare Analytics and Big DataHealth Catalyst
In 2005, Northwestern Memorial Healthcare embarked upon a strategic Enterprise Data Warehousing (EDW) initiative with the Microsoft technology platform as the foundation. Dale Sanders was CIO at Northwestern and led the development of Northwestern’s Microsoft-based EDW. At that time, Microsoft as an EDW platform was not en vogue and there were many who doubted the success of the Northwestern project. While other organizations were spending millions of dollars and years developing EDW’s and analytics on other platforms, Northwestern achieved great and rapid value at a fraction of the cost of the more typical technology platforms. Now, there are more healthcare data warehouses built around Microsoft products than any other vendor. The risky bet on Microsoft in 2005 paid off.
Ten years ago, critics didn’t believe that Microsoft could scale in the second generation of relational data warehouses, but they did. More recently, many of these same pundits have criticized Microsoft for missing the technology wave du jour in cloud offerings, mobile technology, and big data. But, once again, Microsoft has been quietly reengineering its culture and products, and as a result, they now offer the best value and most visionary platform for cloud services, big data, and analytics in healthcare.
In this context, Dale will talk about:
His up and down journey with Microsoft as an Air Force and healthcare CIO, and why he is now more bullish on Microsoft like never before
A quick review of the Healthcare Analytics Adoption Model and Closed Loop Analytics in healthcare, and how Microsoft products relate to both
The rise of highly specialized, cloud-based analytic services and their value to healthcare organizations’ analytics strategies
Microsoft’s transformation from a closed-system, desktop PC company to an open-system consumer and business infrastructure company
The current transition period of enterprise data warehouses between the decline of relational databases and the rise of non-relational databases, and the new Microsoft products, notably Azure and the Analytic Platform System (APS), that bridge the transition of skills and technology while still integrating with core products like Office, Active Directory, and System Center

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptxRASHMI M G
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Hi, I’m William Gunn, Director of Scholarly Communications for Mendeley. In the next 30 minutes, I would like to briefly explain what altmetrics are, how they’re related to other metrics, and how they’re being used at Mendeley and other services you may have used or encountered researchers using.
First, let me tell you why this topic is important enough that we chose to include it in this program. As information science research is starting to show and as the Doge of the Internet proclaims, altmetrics are growing in interest and importance. Scholars are increasingly adopting social media for the discussion and sharing of scholarly content, with Mendeley and Twitter being the largest sources in terms of coverage and volume of events. Mendeley has the largest coverage, which means, for any given article, you’re most likely to find some activity on Mendeley about it relative to other sources. Twitter, owing to sheer size, has the largest volume of events, though only a few percent of articles in any academic discipline are discussed on Twitter, mostly focusing around breaking news, such as the Fukushima nuclear disaster, natural disasters, or health and wellness news of general interest, like the recent news about processed meat being classified as a carcinogen.
Relative to bibliometrics, a term with which most of you will be familiar, altmetrics has drawn more interest, as measured by Google search volume, for the past two years, and has really stolen the show from bibliometrics, which has been in decline for the past several years.
So given that altmetrics is a component of the scholarly ecosystem that’s here to stay, we should probably understand what the alt- part of altmetrics means. One way to think about it is as an alternative to the traditional focus on citations, and another alt- perspective is the focus on a broader universe of scholarly content than just the paper. This schematic shows one view of such as expanded universe of both metrics and objects to which those metrics pertain. One could think of these boxes somewhat like buckets, into which fall various types of activities from which both qualitative and quantitative indicators are derived. Quantitative indicators are the metrics which are the focus on this talk, such as Mendeley readers, but the qualitative dimension, which includes things like blog posts written for a lay audience or tweets referencing a paper highlight the importance of being able to drill into the quantitative number of something into the content from which that event derived. A concrete example here may help: Counting the number of tweets containing a given paper title or DOI may or may not be all that useful, but looking at the actual substance of the tweets is always informative. A tweet from the account of a Nobel laureate is different from am automatically generated tweet when an article goes live, which is different from a jokey tweet about a paper with a funny title. In order to allow the consumer of any metric to make the best decision for them, the current best practice in how the qualitative and quantitative are reconciled in altmetrics is to always provide the raw data underlying any number. These best practices are being developed in a NISO working group, a link to which you can find at the end of this presentation.
So in addition to the qualitative and quantitative dimension I mentioned earlier, there’s an additional dimension of raw data vs. aggregator. Mendeley, Scopus, and Figshare, for example, provide numbers that are as close to raw as possible. With citations, you can see both how many there are and exactly which papers are citing which. Due to the rapid time-scale and privacy concerns, Mendeley shows how many readers a paper has, but does not give detailed information on exactly who those readers are. Over time, this may shift to become more open like citations, but for the moment, we provide the academic status (phd, postdoc, etc), the country, and the discipline of the reader. Moving more in the qualitative direction, you see the post-publication peer review services such as Pubpeer and Publons, but also Pubmed Commons. Moving in the aggregator dimension, you see services such as Impactstory, Altmetric.com, and Plum Analytics, but also Elsevier which is now providing expanded article-level metrics in Scopus. Kudos is an interesting service which takes a hybrid approach. Underscoring the transparency aspect I mentioned earlier, Academia.edu and ResearchGate don’t fit into this schema, because they only provide a opaque number with no ability to drill into the underlying events, but also don’t allow their data to be harvested by aggregators.
I do just want to briefly mention that non-citation based metrics are nothing new, but what is new is the integration of these into a unified framework with citation based metrics and the expanded universe of scholarly content, including datasets, code, presentations, blog posts, tweets, etc.
Now let’s take a quick look at some of the major players individually.
As the source with the greatest coverage, and as my privilege as presenter, I’m going to talk about Mendeley first. You can see the reader numbers I mentioned used in a few different ways on our site. On the catalog pages at mendeley.com, on the right, you can see this paper about the hot topic of next-gen sequencing has 32k readers. you can see a little bit of the demographic breakdown of these, and you can also see how journals stack up based on the number of articles being read from those journals. One thing to highlight here is that while you do see many of the usual suspects in the top 10 list, journals from which the articles are freely available do rank a bit higher, providing a bit of circumstantial evidence that open access publishing is actually important in getting your paper to everyone who would like to read it.
In the Scopus catalog, Mendeley readers are also available, in addition to select items from other activity buckets. One important thing to note here is that in addition to the number, the percentile ranking of the number is shown. That helps a reader to put the number into context. The individual metrics shown here on the sidebar are linked to the metrics tab, which has further information, going all the way to seeing the individual tweets in the case of twitter, or demographics, in the case of Mendeley.
Here’s an example of this further information – across the top of the page are the various activity buckets, with this overview page showing the numbers at a glance.
Drilling further into the social media bucket, you can see the individual tweets, FB posts, and other items.
Another major player in the altmetrics space is altmetric.com As a technical note, because this frequently confuses people, there’s no s on the company name – altmetrics refers to the topic, altmetric (no s).com refers to the company. If you try to go to altmetrics.com, you won’t get anywhere. It’s altmetrics.org or altmetric.com. OK, with that bit of detail out of the way, let’s talk about the company. The main place you’ll encounter them is on a publisher’s article pages, where their colorful little widget shows some of the numbers they aggregate. They don’t provide the percentile rankings, but you can get down to the raw data in many cases, which helps you understand what the numbers mean.
Plum Analytics targets institutions, and they have a similar sort of widget that appears on some repository pages, again without much context, but the neat thing about this is that it works even for content that doesn’t have a DOI, whereas altmetric.com is DOI-based. I also like that they avoid the one-number-to-rule-them-all kind of approach that altmetric.com gives into. They also provide a dashboard so you can see analytics on content across various groupings such as by year, by researcher, or by collection.
In contrast to publishers or institutions, Impact Story focuses on the researcher. It sells itself as a CV, but better. On the left you can see the range of scholarly content types we’ve talked about, with an automatically updated set of metrics appropriate for each type. The use of decals provides context and badges add a layer of behavioral nudges to promote good scholarly behaviors such as publishing open access or utilizing reproducible methodologies.
The hybrid approach of Kudos is apparent here in a page from their site. On one tab there are lay summaries from the authors and on another tab there’s a summary of metrics. In the case of Kudos, the metrics are derived partly from activity on their site and partly from other sources, but are shown only to the authors, so I’ll say nothing further about those.
Moving to more qualitative sources now, let’s take a look at Pubmed Commons. At Pubmed, if you are a published author, you can comment on abstracts on Pubmed. There’s a lot of potential for this to become a major source of commentary based solely on the brand recognition of pubmed and their huge amount of traffic relative to something like PubPeer or even Mendeley. One thing to note here is that the author of the comment is required to sign it with their real name, which is designed to prevent anonymous abuse, but which can also have the effect of suppressing certain voices, particularly those of younger researchers or in other cases where there’s a power imbalance between the commenter and the authors of the paper being commented upon.
As a counterpoint to Pubmed Commons, we have Pubpeer. Comments on Pubpeer do not require registration or disclosure of identity. This has led to a robust culture of critique on the site, but it’s worthwhile noting that allegations of fraud don’t run free here. Commentary is still expected to be fact-based and well-supported and the PubPeer community tends to enforce such norms, providing a strong case that names are required to prevent abusive allegations. It’s also worth pointing out another project called Hypothesis, which isn’t strictly a altmetrics product but rather bills itself as a peer review layer for the web in general, has found a hybrid approach. They allow anonymous commenting, but it’s also not trivially easy for one person to create tons of “sockpuppet” accounts that pretend to have a conversation with each other to create false impressions or derail discussions.
Publons is an effort which seeks to help researchers claim credit for the reviewing work that they do. You can see here that this researcher has claimed 100 reviews, pre-publication, which puts her in the 98% percentile relative to a base population which needs to be made apparent. You can also see some behavioral nudges in the openness score, but it’s a bit hard to understand at first what this means, and the merit score is an example of one of those derived numbers that are generally bad practice.
Finally, if you’ve decided that altmetrics are for you but each of the efforts mentioned before are unusable for some reason, there’s software you can run yourself and freely modify to your liking. This software is called Lagotto and shown here implemented by Crossref as the DOI Event Tracker. The software receives inputs from sources about works registered with it and reports those as events – all of which are highly user-modifiable. For more on this see: http://lagotto.io
So that’s it for the whistlestop tour of the altmetrics landscape. Many of you have questions in your mind about the quality of the data, the utility of it for your use case, the role of commercial players in the ecosystem, and how to address provenance and preservation of these data. Standards to address some of these issues are in the works and expected to, very roughly, follow the outlines of the COUNTER project.
Starting in 2013, an Initiative was begun at NISO to discuss these and other issues, they have resulted in a white paper which I invite you to read for more information. Workgroups on Definitions, Sources, Identifiers, and Quality have been convened and there will be an invitation for public comment before the publication of recommendations and best practices by NISO.
For further information, see the Mendeley Altmetrics group and get involved in the community, which primarily convenes around these two meetings.
