The document discusses why FAIR data principles and the author's 2005 dream of seamlessly integrating data and literature have not been fully realized. It argues that incentives across the research lifecycle from funders to publishers and institutions must change to value open data sharing. While progress is being made with some funders and universities establishing data science programs, challenges remain around complex data, metadata standards, and determining compliance. Overall it presents an optimistic view that with continued coordination among stakeholders to promote reproducible science, FAIR data practices can become the norm.

The objective of this paper is to describe the methods used to develop geographic information systems (GIS) dashboard tool and explain how it can assist nonprofit hospitals to identify priority neighborhoods. Multiple data sources from the 500 Cities Project databases were analyzed, and two online dashboards were created. The first dashboard is a hospital-specific composite dashboard, and the second is a comparison dashboard of health outcomes identified by both the hospital and the county’s community health needs assessment focused on neighborhood-level disparities. Hospital-specific health outcomes were Stroke, Diabetes, and Coronary Heart Disease. County-specific health outcomes were Obesity, Dental, and Mental Health. All of the six health outcomes were standardized, rescaled, and weighted within the final composite score. Tableau was used for developing the dashboards and geographically mapping the analyzed data. The maps were developed specifically for a large hospital in Florida; however, this methodology can be utilized by other hospitals across the US. City-specific data is essential to ensure the accuracy of community health needs. The development of an interactive, comprehensive map using Tableau is a useful tool for visualizing target neighborhoods for community health outreach. The integration of community needs assessment findings into the development of composite scores allows hospitals in the US to use this tool to inform community health outreach strategy adequately.

Data Management and Broader Impacts: a holistic approachMegan O'Donnell
[please download to view at full resolution]
The National Science Foundation’s (NSF) Broader Impacts Criterion asks scientists to frame their research beyond “science for science’s sake.” Examining data and data management through a Broader Impacts lens highlights the benefits of good data management, data management plans (DMPs), and strengthens the argument for better Data Information Literacy (DIL) in the sciences.
Information Use in Natural Habitats: A Comparative Study of Graduates in the ...Siobhán Dunne
Two librarians working with journalism students in higher education institutions in Ireland and Canada designed a comparative research study which surveyed graduates about the information resources they used to accomplish key communications tasks in their professional roles. The aim of the study was to (a) identify resources being used in practice and (b) harness that knowledge to improve both the content of information skills programmes and the pedagogical approach for teaching those skills. We were curious about the resources graduates actually used at work, both in traditional journalism positions and more broadly in other fields of communications.
An analysis of current professional journalism standards (Accrediting Council on Education in Journalism and Mass Communication 2012; National Council for the Training of Journalists 2012, 2014) and recent articles on information use by journalists (Machill & Bieller 2009; Wenger & Owens 2013) shows a disconnect between what journalists are expected to use and what they really use in daily practice. Literature on information literacy instruction for journalism students is quite descriptive about the resources we teach students in these programs but this is not always connected to what they might use in practice, in particular as they often have access to different resources than those provided by institutional subscriptions. Missing from the literature entirely is the consideration of journalists working in other communications roles.
Drawing on their prior work and other major studies, the authors will present recommendations for refining classroom practice to foster greater transfer of information literacy skills. We will present data from the survey and discuss the challenges the results present both in terms of what and how we teach in information literacy sessions for professional programs. Participants will be invited to complete a predictive version of the survey to compare what they think these professionals said with our results. This will be the basis for a discussion not only of our results, but also of our process, and how it might inform similar projects.
Although the focus of this study relates to employability skills in the field of journalism and communications, we will discuss the transferability of our findings and how our approach enables implications to be drawn for programmes that prepare students for future careers in other disciplines. Participants will be encouraged to generate questions they could use in similar surveys of graduates in other programs. Both librarians already work closely with faculty on existing journalism programmes; this paper will discuss how the insights gained from the study have been shared with colleagues to improve programmes for future students.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

16. PLOS Data Policy
• PLOS journals require authors to make all data underlying the findings
described in their manuscript fully available without restriction at the
time of publication. When specific legal or ethical requirements
prohibit public sharing of a dataset, authors must indicate how
researchers may obtain access to the data.
• When submitting a manuscript, authors must provide a Data
Availability Statement describing compliance with PLOS's policy. If the
article is accepted for publication, the data availability statement will
be published as part of the accepted article.
• Reliance on resources whose sustainability is unknown
• Who checks?
July 23, 2019 ISMB 2019 16
17. >100,000
papers published with a data statement at PLOS
<0.1%
of submissions rejected due to authors’
unwillingness or inability to share data
~20%
of submissions use data repositories
From Emma Ganley @ PLOS
19. Challenges
• Research areas such as clinical studies require more
complex data sharing considerations and data release
mechanisms. Community input is important for policy
implementation
• Data citations and mechanisms to provide author
credit need to see a stronger uptake
• Metadata of published data sets is often lacking,
needs community-agreed standards
• It is not always clear what constitutes compliance
From Emma Ganley @ PLOS
20. Related PLOS Efforts Beyond Data
• Moving towards a software sharing policy
• Working a pilot with CodeOcean to include executable code in
publications
• Notion of reproducible models
• Emphasizing benchmarking section to show the value of data
July 23, 2019 ISMB 2019 20
21. Summary - Why Has FAIR (Let Alone My
Dream) Not Been Realized (Optimistic View)?
• It starts with funder incentives – things are looking up
• Institutions have a role to play – the value of data is slowly
being realized
• Small publishers like PLOS have limited leverage - publishers
need to coordinate

There is a natural tension for scientists and researchers who are busy and already tend to work long hrs
They want recognition for their work, and the current currency is published manuscripts
They don’t want to do things that they perceive as unnecessary extras – providing more info, adhering to reporting guidelines, gathering all metadata, doing something sensible with data somewhere etc.
