Many of us nowadays invest significant amounts of time in sharing our activities and opinions with friends and family via social networking tools. However, despite the availability of many platforms for scientists to connect and share with their peers in the scientific community the majority do not make use of these tools, despite their promise and potential impact and influence on our future careers. We are being indexed and exposed on the internet via our publications, presentations and data. We also have many more ways to contribute to science, to annotate and curate data, to “publish” in new ways, and many of these activities are as part of a growing crowdsourcing network. This presentation will provide an overview of the various types of networking and collaborative sites available to scientists and ways to expose your scientific activities online. Many of these can ultimately contribute to the developing measures of you as a scientist as identified in the new world of alternative metrics. Participating offers a great opportunity to develop a scientific profile within the community and may ultimately be very beneficial, especially to scientists early in their career.
A presentation given at the ACS CINF Meeting in Denver on March 22nd 2015
The authoring of a scientific publication can represent the culmination of many tens if not 100s of hours of data collection and analysis. The authoring and peer-review process itself often represents a major undertaking in terms of assembling the publication and passing through review. Considering the amount of work invested in the production of a scientific article it is therefore quite surprising that authors, post-publication, invest very little effort in communicating the value and potential impact of their article to the community. Social networking has clearly demonstrated the ability to self-market and drive attention. At the same time, the increasing volume of literature (over a million new articles are published every year), requires authors to take on a more direct role in ensuring their work gets read and cited. This requirement may grow with the emergence of a range of metrics at the article level, shifting attention away from where a researcher publishes to the performance of their individual articles. Therefore, a separate platform to facilitate social networking and other discovery tools to communicate the value of published science to the community would be of value. In parallel the possibility to enhance an article by linking to additional information (presentations, videos, blog posts etc) allows for enrichment of the article post-publication, a capability not available via the publishers platform. This presentation will provide a personal overview of the experiences of using the Kudos Platform and how it ultimately benefits my ability to communicate an integrated view of my research to the community.
The Royal Society of Chemistry hosts one of the worlds’ richest collections of online chemistry data that is free-to-access for the community. ChemSpider presently hosts over 30 million unique chemical compounds together with associated data and accessible via a number of search techniques. With almost 50,000 unique users per day from around the world the site offers scientists the ability to investigate the world of small molecules via property searches, analytical data and predictive models. The challenges associated with providing a similar platform for “materials” are manifold but, if they could be addressed, would offer a valuable service to the materials community. This presentation will provide an overview of how ChemSpider was built, our efforts to expand the capabilities to a more encompassing data repository and some of the challenges faced to embrace the diverse world of materials informatics and online data access.

Despite the availability of many platforms for scientists to connect and share with their peers in the scientific community the majority do not make use of these tools, despite their promise and potential impact and influence on our careers. We are already being indexed and exposed on the internet via our publications, presentations and data and new “AltMetric scores” are being assigned to scientific publications as measures of popularity and, supposedly, of impact. We now have even more ways to contribute to science, to annotate and curate data, to “publish” in new ways, and many of these activities are as part of a growing crowdsourcing network. This presentation provides an overview of the various types of networking and collaborative sites available to scientists and ways to expose your scientific activities online. It will discuss the new world of AltMetrics that is in an explosive growth curve and will help you understand how to influence and leverage some of these new measures. Participating online, whether it be simply for career advancement or for wider exposure of your research, there are now a series of web applications that can provide a great opportunity to develop a scientific profile within the community.
Many students spend enormous amounts of their time engaged with their computers, accepting of course that mobile devices are simply computers of a different form factor. Engaged with the social networks, utilizing computer platforms to source and share content of various forms, their contributions of “data” into what is the cloud, and in many cases a void, is enormous. What community and career benefit might result from those students spending some of their time contributing chemistry related data to the world? What challenges lie in the way of their participation and how might participating have a positive, or negative impact on their future career. The Royal Society of Chemistry hosts a number of chemistry data platforms to which students can actively contribute and for which their participation can be measured. Moreover the RSC’s micropublishing platform allows chemists to learn how to write up their scientific work, obtain review from their peers and chemistry professors in a non-threatening environment and produce an online published work in less than day that is both citable and available as a shared resource for the community. This presentation will demonstrate how to participate and encourage engagement from students early in their education. There are no longer any technology barriers to the sharing of the majority of chemistry related data.

Our access to scientific information has changed in ways that were hardly imagined even by the early pioneers of the internet. The immense quantities of data and the array of tools available to search and analyze online content continues to expand while the pace of change does not appear to be slowing. ChemSpider is one of the chemistry community’s primary online public compound databases. Containing tens of millions of chemical compounds and its associated data ChemSpider serves data tens of thousands of chemists every day and it serves as the foundation for many important international projects to integrate chemistry and biology data, facilitate drug discovery efforts and help to identify new chemicals from under the ocean. This presentation will provide an overview of the expanding reach of the ChemSpider platform and the nature of the solutions that it helps to enable. We will also discuss the possibilities it offers in the domain of crowdsourcing and open data sharing. The future of scientific information and communication will be underpinned by these efforts, influenced by increasing participation from the scientific community and facilitated collaboration and ultimately accelerate scientific progress.
Many people are surprised to learn that, even though they don’t participate on social media and only use their computers for work, they have a digital life. This is partly because publicly-available information about you is collected from the internet, and this information is used by companies to create records about you. Join Kimberley Barker for an overview of topics such as digital privacy, online reputation management, personal branding, and online identity.

Public engagement while you sleep? How altmetrics can help researchers broade...UoLResearchSupport
Slides from a seminar delivered for pepnet at the University of Leeds 28 Nov 2018. Thanks to Charlotte Perry-Houts for extra content:
From peer reviewed journal articles, to assorted reports and grey literature, to datasets comprising numerical, textual or multimedia files; we generate thousands of research outputs.
In this session, Kirsten Thompson (OD&PL) and Nick Sheppard (Library) will discuss strategies for increasing quality online engagement with that research. We will explore how you can use ‘alternative metrics’, more commonly known as ‘altmetrics’, to monitor such engagement. Altmetrics can help to showcase the reach of your work, supplement grant and tenure applications, identify new audiences, and connect with other researchers in your discipline.
In the age of “fake news”, academics have a responsibility to share their expertise beyond the Ivory Tower. We’ll show you how to ensure all these disparate outputs are properly curated in university repositories with a Digital Object Identifier (DOI). There will also be an opportunity to learn about and contribute to the Library led Data Management Engagement Award, a first-ever competition launched to elicit new and imaginative ideas for engaging researchers in the practices of good Research Data Management (RDM).
How altmetrics can help researchers broaden the reach of their work. Workshop facilitated by Kirsten Thompson and Nick Sheppard at the University of Leeds for the #PepnetLeeds network November 28th 2018.
With the progress towards open science, scientific communication is facing a new wave of innovations towards more openness and speed of research publication which will deeply affect the way the peer review function is carried out and the overall role of journals in assuring quality and adding value to manuscripts.
Several initiatives are promoting the generalized adoption of open access preprints as a formal beginning stage of research publication, which has been common since the 90’s in the physics community. And, in the last decade, new ways to carry out the evaluation of manuscripts have emerged either to replace or to improve the traditional methods, which are widely criticized as being slow and expensive in addition to lacking transparency.
Quality nonprofit journals from emerging and developing countries have succeeded to follow the main innovations brought by the Internet. In addition to the technicalities of the digital publishing, there is a wide adoption of Open Access in the international flow of scientific information. The new wave of innovations that affect the peer review function and the changing role of journals pose new challenges to the emerging and developing countries in regard of scientific publishing. The adoption of these innovations is essential for progress of SciELO as a leading open access program to enhance scientific communication.
The scope of this workshop aims at an in-depth analysis and discussion of the state of art and main trends of the peer review function, the modalities of carrying it out as well as of the increasing adoption of mechanisms to speed publication such as preprints and how they affect and potentially renew the role of journals. These recommendations will guide SciELO policies on manuscript evaluation and on the adoption of preprint publications.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
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.
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.
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.

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.

possible problems with traditional journals
• Pseudo-monopoly - market signals don’t work
• Huge increase in submissions
• ⇒ price increase
• Could this be solved by Open Access?
Maybe, maybe not
Problems/
14/35 Changes
28. Types of publications -
new types of journals
• Pure Open Access journals (OA gold)
• You pay for publishing - reading is free
• Changes to peer review
• post-peer review
• Incorporated article metrics

32. PLOS ONE
• Open for all fields of science
• Impact factor: 3.534 (2013)
• 31520 articles published 2013
• Publication cost: USD 1350
• Peer review: a bit different

33. PLOS ONE -
peer review
Problems/
Changes
The “interest” will not be assessed by the referees
Instead, there is a “post-peer review”, via comments and metrics

40. Types of publications -
new types of journals
Other new journals
Do we dilute science publishing? Problems/
20/35 Changes
41. Types of publications -
not limited by articles
• Data
• Software
• Images
• Videos
• Experimental setups
• Negative results
• Reproduction of previous
research
Problems/
21/35 Changes
42. Biomedicine rules
Problems/
Changes
Many policies based on needs in biomedicine
Things are different in fields less intense on citations
This is not necessarily good for us
22/35
45. Societal impact
• Citations
• Downloads
• Saves in Mendeley,
etc.
• Mentions in books
• Wikipedia
• Exposure in media
• Blogs
• Social media
• Patents
• Impact on legislation
• Policy documents
How can such things be measured, and
normalized in a fair way? What’s
25/35 happening now?
58. It’s not just about evaluations
• Can facilitate literature searches GREATLY!
• Helps me select between thousands of articles
• Vanity! Who reads my article?
What’s
28/35 happening now?
60. What should we do?
Do we need to
adapt?
Does everything have to be evaluated?
Isn’t peer review enough?
Can competence ever be reduced to a number?
A world totally void of quantified
evaluations will probably never exist
30/35
61. Unfortunately unavoidable
Do we need to
adapt?
Someone WILL measure our work.
Isn’t better if we have some insight/control in this?
31/35
62. Who should decide how
science is evaluated?
Do we need to
adapt?
Maybe we need a new, community driven, non-for
profit organization?
Maybe a good thing that we have more
than ONE type of measuring?
32/35
63. Should we register at all these sites?
Should we be active on social media?
ORCID Yes!
ResearchID, Google scholar,
Scopus, PubMed ……
Maybe
twitter, blogs If you like it
Mendeley, Zotero ….. If it helps your productivity
Do we need to
33/35 adapt?
64. What is the value of a
scientific article?
Should we persist with articles as the only true
method for dissemination and evaluation?
Do we need to
adapt?
Think about it!
34/35
65. What is the value of a
scientific article?
The general public is ignorant about science (?)
Do we need to
adapt?
Who’s fault is that?
Think about it!
34/35
66. What is the value of a
scientific article?
The younger among us may need to adapt!
Do we need to
adapt?
• New types of journals
• New types of metrics
• Social media and such nonsense
Think about it!
