    Objective: To create a medical library terms taxonomy in order to find trends in the medical library literature. In order to explore trends in scholarly publishing by health sciences librarians in the last five years, we endeavored to examine keywords used in articles published in four health sciences library journals during this time. From our initial review we determined that: author-created keywords are not always based on a controlled vocabulary; MeSH subheadings do not include terms unique to the library field; and Library of Congress taxonomy is too broad. Thus, it was necessary to create a taxonomy by grouping similar keywords into categories in order to accurately identify trends. Methods: Citations from four health sciences library journals from 2016-2020 were exported from PubMed and EBSCO Academic Search Premier into EndNote X9. Keywords from all citations were exported from EndNote as a text file and then imported into Microsoft Excel. Pivot tables were used to determine the number of times each keyword was used and to aggregate identical keywords. A team of six librarians with a variety of skill sets and backgrounds reviewed each keyword to determine how to categorize and group terms to create a taxonomy. Results: 8,806 keywords from the journals were downloaded into spreadsheets and aggregated. Pivot tables were used to combine identical terms resulting in 2,801 unique keywords which are currently being categorized to complete the taxonomy. Conclusion: While choosing keywords without use of a controlled vocabulary when submitting a manuscript allows for flexibility and customization, and might result in better retrieval during natural language searching, what we discovered through this project is that choosing keywords without the use of a controlled vocabulary makes it difficult to see trends and to conduct a bibliometric analysis

    Previous investigations into trends in Library and Information Science (LIS) literature have revealed changes in the topics librarians publish on over time, with older studies highlighting classification and indexing, and information retrieval and more recent studies highlighting keywords such as internet, information technology, digital libraries, and again, information retrieval. No similar investigation has been conducted on current publication trends by health sciences librarians. This study analyzes the top themes on which health sciences librarians published from 2016 to 2020 by examining the frequency of keywords. Keywords and subject headings were analyzed from The Journal of the Medical Library Association, Medical References Services Quarterly, The Journal of Hospital Librarianship, and The Journal of Electronic Resources in Medical Libraries. A total of 8,806 keywords were downloaded for analysis and organized into 292 categories during taxonomy creation. The ten most frequent themes were: libraries, information, education, humans, demography, librarian, geographical locations, research, electronic resources, and technology. The study also found that data, psychiatry and psychology, informatics, and publishing were other key themes, indicating that health sciences librarians are publishing on a wide range of topics. Some keywords that appeared only once, such as telecommuting and flexible staffing, suggest emerging areas of research for librarians

    The University of Central Florida Health Sciences Library is a digital library with 98% of resources being electronic and available online. Though almost all aspects of the library’s operations were impacted by the closing of the physical space during the coronavirus pandemic, being a digital library helped the library team transition quickly to remote reference, programming and instruction services

    The role of miniaturization in the evolution of the mammalian jaw and middle ear

    Get PDF
    The evolution of the mammalian jaw is one of the most important innovations in vertebrate history, and underpins the exceptional radiation and diversification of mammals over the last 220 million years. In particular, the transformation of the mandible into a single tooth-bearing bone and the emergence of a novel jaw joint—while incorporating some of the ancestral jaw bones into the mammalian middle ear—is often cited as a classic example of the repurposing of morphological structures. Although it is remarkably well-documented in the fossil record, the evolution of the mammalian jaw still poses the paradox of how the bones of the ancestral jaw joint could function both as a joint hinge for powerful load-bearing mastication and as a mandibular middle ear that was delicate enough for hearing. Here we use digital reconstructions, computational modelling and biomechanical analyses to demonstrate that the miniaturization of the early mammalian jaw was the primary driver for the transformation of the jaw joint. We show that there is no evidence for a concurrent reduction in jaw-joint stress and increase in bite force in key non-mammaliaform taxa in the cynodont–mammaliaform transition, as previously thought. Although a shift in the recruitment of the jaw musculature occurred during the evolution of modern mammals, the optimization of mandibular function to increase bite force while reducing joint loads did not occur until after the emergence of the neomorphic mammalian jaw joint. This suggests that miniaturization provided a selective regime for the evolution of the mammalian jaw joint, followed by the integration of the postdentary bones into the mammalian middle ear

    The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance.

    Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the pandemic on the continent, a number that now exceeds 100,000 genomes. Our results show an increase in the number of African countries that are able to sequence domestically and highlight that local sequencing enables faster turnaround times and more-regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and illuminate the distinct dispersal dynamics of variants of concern-particularly Alpha, Beta, Delta, and Omicron-on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve while the continent faces many emerging and reemerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

    The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

    INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

    Phenomenology in practice: Towards a methodology for a 'subjective' approach

    No full text
    The article deals with the practice of phenomenological archaeological fieldwork, which is concerned with sensory experience of landscapes and locales. Phenomenological approaches in archaeology have cast light on aspects of past human experience not addressed by traditional archaeological methods. So far, however, they have neither developed explicit methodologies nor a discussion of methodological practice and have laid themselves open to accusations of being 'subjective' and 'unscientific'. This article describes and explores three experiments in phenomenological archaeology developed in the context of the Tavoliere-Gargano Prehistory Project and carried out on Neolithic settlement sites of the type known as villaggi trincerati. Our aims are both to develop explicit methods for this type of fieldwork and to combine phenomenology with other more traditional approaches, such as those concerned with technological, economic and environmental aspects of landscapes and sites. Our work also differs from other phenomenological archaeology in its concern with familiar, everyday experience and domestic contexts, rather than exceptional, special experience in ritual contexts. We consider how our particular approach might be used to further understandings of past lives. Copyright © 2006 SAGE Publications
