sage white paper on Discoverability in the twenty first century collaboration opportunities for publishers vendors and librarians
against the grain, 2016Co-Authors: Mary M SomervilleAbstract:Discoverability enables scholars to locate the content needed to advance their research and other creative activities. Improved discovery experiences require heightened collaboration among: (1) scholarly publishers and their published authors; (2) search engine developers, database providers, abstracting and indexing services, and academic publishers; (3) electronic resource management and integrated library system vendors, and ; (4) librarians who advance institutional Discoverability. To further exploratory cross-sector conversations, SAGE commissioned a White Paper, "Improving Discoverability of Scholarly Content in the Twentieth Century: Collaboration Opportunities for Librarians, Publishers, and Vendors," released in January 2012. The research report presents highlights of interviews conducted from July to October 2011 with fourteen value chain experts. The White Paper also summarizes results of peer-reviewed publications and proprietary research studies to further characterize the currently fragmented discovery environment. In conclusions, the authors propose cross-sector conversations among publishers, vendors, and librarians to further visibility and, ultimately, usage of the scholarly corpus on the open Web and within library services.

collaborative improvements in the Discoverability of scholarly content accomplishments aspirations and opportunities a sage white paper
2014Co-Authors: Mary M Somerville, Lettie Y ConradAbstract:The life cycle of academic works is supported by extensive cross-sector collaboration throughout the scholarly communications ecosystem. In recent years, traditional codes of practice have been disturbed. In response, in 2012, SAGE published a white paper that offered conversation starters for reinventing conventions and relationships among libraries, publishers, and service providers. To carry on the investigation of the first white paper, Improving Discoverability of Scholarly Content in the Twentieth Century: Collaboration Opportunities for Librarians, Publishers, and Vendors, this paper explores the latest accomplishments, aspirations, opportunities, and challenges for improved Discoverability of scholarly content. As the discovery landscape is rapidly shifting, this paper demonstrates that progress continues to depend on core principles of cross-sector collaboration, taking the form of these actionable recommendations for anyone in scholarly communications: - Standards: When relevant, all sectors should participate in ratified standards to ensure that cooperation is part of business-as-usual routines. - Transparency: Standards compliance is critical for successful discovery, and the development, implementation, and enforcement of these standards require open relationships across the industry focused on reaching our shared goals. - Metadata: Quality metadata, observing ratified standards, enables successful discovery of scholarly content, products, and services. - Partnerships: Opportunities exist for new discovery innovations across the industry, such as linked open data and cross-publisher discovery tools.

Discoverability challenges and collaboration opportunities within the scholarly communications ecosystem a sage white paper update
Collaborative Librarianship, 2013Co-Authors: Mary M Somerville, Lettie Y ConradAbstract:The prominence of mainstream search engines and the rise of web-scale, pre-indexed discovery services present new challenges and opportunities for publishers, librarians, vendors, and researchers. With the aim of furthering collaborative conversations, SAGE commissioned a study of opportunities for improving academic Discoverability with value chain experts in the scholarly communications ecosystem. Results were released in January 2012 as a white paper titled Improving Discoverability of Scholarly Content in the Twentieth Century: Collaboration Opportunities for Librarians, Publishers, and Vendors. Following the white paper, this article explores the implications for these findings through review of commissioned studies, research reports, journal articles, conference papers, and white papers published in the ensuing twelve months. Sidebars highlight especially promising cross-sector initiatives for enhancing researcher Discoverability of the scholarly corpus at appropriate points in their workflow, including the NISO Open Discovery Initiative (ODI) and the Open Researcher and Contributor ID (ORCID). Concluding reflections highlight opportunities for librarians to contribute to cross-sector collaborations that support discovery of quality peer-reviewed content by improving navigation, Discoverability, visibility, and usage of the scholarly corpus.

improving the Discoverability of scholarly content in the twenty first century collaboration opportunities for librarians publishers and vendors a sage white paper
2012Co-Authors: Mary M Somerville, Barbara Schader, John SackAbstract:Discoverability is a popular buzzword—ultimately meaning the degree to which scholars can locate the content needed to advance their research and other creative activity. Improved user discovery experiences require heightened collaboration among: (1) scholarly publishers and their published authors; (2) search engine developers, database providers, abstracting and indexing services, and academic publishers; (3) electronic resource management and integrated library system vendors, and; (4) librarians who advance institutional Discoverability. Drawing from interviews with value chain experts, results of research studies, and insights from scholarly literature, this white paper assesses the currently fragmented discovery environment and proposes cross-sector conversations to further visibility and, ultimately, usage of the scholarly corpus, not only on the open web, but within library services.

quantifying the polygenic architecture of the human cerebral cortex extensive genetic overlap between cortical thickness and surface area
Cerebral Cortex, 2020Co-Authors: Chihua Chen, Oleksandr Frei, Dennis Van Der Meer, Jennifer Monereo Sanchez, Tobias Kaufmann, Wesley K Thompson, Kevin Oconnell, David Edmund Johannes LindenAbstract:The thickness of the cerebral cortical sheet and its surface area are highly heritable traits thought to have largely distinct polygenic architectures. Despite large-scale efforts, the majority of their genetic determinants remain unknown. Our ability to identify causal genetic variants can be improved by employing brain measures that better map onto the biology we seek to understand. Such measures may have fewer variants but with larger effects, that is, lower polygenicity and higher Discoverability. Using Gaussian mixture modeling, we estimated the number of causal variants shared between mean cortical thickness and total surface area, as well as the polygenicity and Discoverability of regional measures. We made use of UK Biobank data from 30 880 healthy White European individuals (mean age 64.3, standard deviation 7.5, 52.1% female). We found large genetic overlap between total surface area and mean thickness, sharing 4016 out of 7941 causal variants. Regional surface area was more discoverable (P = 2.6 × 10-6) and less polygenic (P = 0.004) than regional thickness measures. These findings may serve as a roadmap for improved future GWAS studies; knowledge of which measures are most discoverable may be used to boost identification of genetic predictors and thereby gain a better understanding of brain morphology.

quantifying the polygenic architecture of the human cerebral cortex extensive genetic overlap between cortical thickness and surface area
bioRxiv, 2019Co-Authors: Dennis Van Der Meer, Jennifer Monereo SanchezAbstract:Introduction: The thickness of the cerebral cortical sheet and its surface area are highly heritable traits thought to have largely distinct polygenic architectures. Despite large-scale efforts, the majority of their genetic determinants remains unknown. Our ability to identify causal genetic variants can be improved by employing better delineated, less noisy brain measures that better map onto the biology we seek to understand. Such measures may have fewer variants but with larger effects, i.e. lower polygenicity and higher Discoverability. Methods: Using Gaussian mixture modeling, we estimated the number of causal variants shared between mean cortical thickness and total surface area. We further determined the polygenicity and Discoverability of regional cortical measures from five often-employed parcellation schemes. We made use of UK Biobank data from 31,312 healthy White European individuals (mean age 55.5, standard deviation (SD) 7.4, 52.1% female). Results: Contrary to previous reports, we found large genetic overlap between total surface area and mean thickness, sharing 4427 out of 7150 causal variants. Regional surface area was more discoverable (p=4.1x10-6) and less polygenic (p=.007) than regional thickness measures. We further found that genetically-informed and less granular parcellation schemes had highest Discoverability, with no differences in polygenicity. Conclusions: These findings may serve as a roadmap for improved future GWAS studies; Knowledge of which measures or parcellations are most discoverable, as well as the genetic overlap between these measures, may be used to boost identification of genetic predictors and thereby gain a better understanding of brain morphology.

practices in code Discoverability astrophysics source code library
ASPC, 2012Co-Authors: Alice Allen, Peter J Teuben, Robert J Nemiroff, Lior ShamirAbstract:Here we describe the Astrophysics Source Code Library (ASCL), which takes an active approach to sharing astrophysical source code. ASCL’s editor seeks out both new and old peer-reviewed papers that describe methods or experiments that involve the development or use of source code, and adds entries for the found codes to the library. This approach ensures that source codes are added without requiring authors to actively submit them, resulting in a comprehensive listing that covers a significant number of the astrophysics source codes used in peer-reviewed studies. The ASCL now has over 340 codes in it and continues to grow. In 2011, the ASCL1 has on average added 19 new codes per month. An advisory committee has been established to provide input and guide the development and expansion of the new site, and a marketing plan has been developed and is being executed. All ASCL source codes have been used to generate results published in or submitted to a refereed journal and are freely available either via a download site or from an identified source. This paper provides the history and description of the ASCL. It lists the requirements for including codes, examines the benefits of the ASCL, and outlines some of its future plans. Note: we don’t seem to have a reference (Teuben et al. 2012) for our other paper. 1. History of the ASCL In 1999, Robert Nemiroff and John F. Wallin founded the online Astrophysics Source Code Library (ASCL) to house codes of use to the community.? This was a volunteer, spare-time endeavor and resulted in a library of 37 codes which had been described in the literature and used to produce research published in or submitted to refereed journals. Twenty-seven of the codes were added to the library in 1999; the last code was added in 2002. The ASCL site also linked to other code libraries, most of which no longer exist or have not been updated in years. In 2003, a search for a new editor for 1http://asterisk.apod.com/viewforum.php?f=35 1

practices in code Discoverability
arXiv: Instrumentation and Methods for Astrophysics, 2012Co-Authors: Peter J Teuben, Alice Allen, Robert J Nemiroff, Lior ShamirAbstract:Much of scientific progress now hinges on the reliability, falsifiability and reproducibility of computer source codes. Astrophysics in particular is a discipline that today leads other sciences in making useful scientific components freely available online, including data, abstracts, preprints, and fully published papers, yet even today many astrophysics source codes remain hidden from public view. We review the importance and history of source codes in astrophysics and previous efforts to develop ways in which information about astrophysics codes can be shared. We also discuss why some scientist coders resist sharing or publishing their codes, the reasons for and importance of overcoming this resistance, and alert the community to a reworking of one of the first attempts for sharing codes, the Astrophysics Source Code Library (ASCL). We discuss the implementation of the ASCL in an accompanying poster paper. We suggest that code could be given a similar level of referencing as data gets in repositories such as ADS.

making search engines notice an exploratory study on Discoverability of dspace metadata and pdf files
Journal of Web Librarianship, 2016Co-Authors: Le YangAbstract:ABSTRACTThis study analyzed the search results of four main Internet search engines on three newly created digital collections at Texas Tech University Libraries, in order to assess the search engine indexing on metadata and PDF files of digital items that are published in the institutional repository. The exploratory study found that only one search engine discovered PDF files, while the others only discovered metadata. The results of the study also suggested that metadata and PDF files can supplement each other to facilitate Discoverability of the digital collections on search engines, and revealed some findings that are contradictory to conclusions in previous research.
