Mapping structural differences between 30S ribosomal subunit assembly intermediates

Under appropriate conditions, functional Escherichia coli 30S ribosomal subunits assemble in vitro from purified components. However, at low temperatures, assembly stalls, producing an intermediate (RI) that sediments at 21S and is composed of 16S ribosomal RNA (rRNA) and a subset of ribosomal proteins (r-proteins). Incubation of RI at elevated temperatures produces a particle, RI*, of similar composition but different sedimentation coefficient (26S). Once formed, RI* rapidly associates with the remaining r-proteins to produce mature 30S subunits. To understand the nature of this transition from RI to RI*, changes in the reactivity of 16S rRNA between these two states were monitored by chemical modification and primer extension analysis. Evaluation of this data using structural and biochemical information reveals that many changes are r-protein–dependent and some are clustered in functional regions, suggesting that this transition is an important step in functional 30S subunit formation.

Beyond citation analysis: a model for assessment of research impact

QUESTION Is there a means of assessing research impact beyond citation analysis? SETTING The case study took place at the Washington University School of Medicine Becker Medical Library. METHOD This case study analyzed the research study process to identify indicators beyond citation count that demonstrate research impact. MAIN RESULTS The authors discovered a number of indicators that can be documented for assessment of research impact, as well as resources to locate evidence of impact. As a result of the project, the authors developed a model for assessment of research impact, the Becker Medical Library Model for Assessment of Research. CONCLUSION Assessment of research impact using traditional citation analysis alone is not a sufficient tool for assessing the impact of research findings, and it is not predictive of subsequent clinical applications resulting in meaningful health outcomes. The Becker Model can be used by both researchers and librarians to document research impact to supplement citation analysis.

Librarians as Part of Cross-Disciplinary, Multi-institutional Team Projects: Experiences from the VIVO Collaboration

Cross-disciplinary, team-based collaboration is essential for addressing todays complex research questions, and librarians are increasingly entering into such collaborations. This study identifies skills needed as librarians integrate into cross-disciplinary teams, based on the experiences of librarians involved in the development and implementation of VIVO, a research discovery and collaboration platform. Participants discussed the challenges, skills gained, and lessons learned throughout the project. Their responses were analyzed in the light of the science of team science literature, and factors affecting collaboration on the VIVO team were identified. Skills in inclusive thinking, communication, perseverance, adaptability, and leadership were found to be essential.

Integration of Web 2.0 Technologies in the Translational Research Environment

Recent advancements in translational medicine have created an urgent need for solutions that support information dissemination and facilitate a fluid exchange of data from the research laboratory to the clinical environment and on to the broader community. Medical libraries can help meet this need by incorporating emerging Web-based technologies in support of educational, research, and patient care objectives. Web 2.0 resources facilitate creativity, collaboration, and sharing among users. Integration of Web 2.0 resources allows scientists, students, and medical professionals to efficiently organize and manage the information and resources that are critical in todays quickly changing biomedical research environment.

This article discusses an innovative course to educate the next generation of librarians and meet the demands of the changing health information environment.

Library-based clinical and translational research support.

There has been a shift in the workflow at academic biomedical research and clinical care centers to promote more efficient clinical and community implementation of bench discoveries. Strong financial support for this effort is provided by the Clinical and Translational Science Awards (CTSAs) from the National Center for Advancing Translational Sciences (NCATS), National Institutes of Health (NIH), awarded to about sixty biomedical research institutions constituting the CTSA Consortium [1]. CTSAs offer an opportunity to speed the translation of bench discoveries to improved human health by transforming the

Research discovery through linked open data

VIVO is an open source semantic web platform that contains information about scholars and their interests and activities. This demonstration will highlight the platform and ontology, data sources, features of the software and the ways that VIVO data can be leveraged for a variety of purposes within and beyond an institution to facilitate collaboration and research discovery.

Academic information on Twitter: A user survey

Although counts of tweets citing academic papers are used as an informal indicator of interest, little is known about who tweets academic papers and who uses Twitter to find scholarly information. Without knowing this, it is difficult to draw useful conclusions from a publication being frequently tweeted. This study surveyed 1,912 users that have tweeted journal articles to ask about their scholarly-related Twitter uses. Almost half of the respondents (45%) did not work in academia, despite the sample probably being biased towards academics. Twitter was used most by people with a social science or humanities background. People tend to leverage social ties on Twitter to find information rather than searching for relevant tweets. Twitter is used in academia to acquire and share real-time information and to develop connections with others. Motivations for using Twitter vary by discipline, occupation, and employment sector, but not much by gender. These factors also influence the sharing of different types of academic information. This study provides evidence that Twitter plays a significant role in the discovery of scholarly information and cross-disciplinary knowledge spreading. Most importantly, the large numbers of non-academic users support the claims of those using tweet counts as evidence for the non-academic impacts of scholarly research.

The repository was designed to allow scholars the ability to create, share, and preserve a range of citable digital outputs. This article traces the evolution of DigitalHub’s development and engagement activities, highlighting project challenges, innovations, success stories, and the team-based approach that was employed to successfully achieve project goals.

Research evaluation support services in biomedical libraries

Objective The paper provides a review of current practices related to evaluation support services reported by seven biomedical and research libraries. Methods A group of seven libraries from the United States and Canada described their experiences with establishing evaluation support services at their libraries. A questionnaire was distributed among the libraries to elicit information as to program development, service and staffing models, campus partnerships, training, products such as tools and reports, and resources used for evaluation support services. The libraries also reported interesting projects, lessons learned, and future plans. Results The seven libraries profiled in this paper report a variety of service models in providing evaluation support services to meet the needs of campus stakeholders. The service models range from research center cores, partnerships with research groups, and library programs with staff dedicated to evaluation support services. A variety of products and services were described such as an automated tool to develop rank-based metrics, consultation on appropriate metrics to use for evaluation, customized publication and citation reports, resource guides, classes and training, and others. Implementing these services has allowed the libraries to expand their roles on campus and to contribute more directly to the research missions of their institutions. Conclusions Libraries can leverage a variety of evaluation support services as an opportunity to successfully meet an array of challenges confronting the biomedical research community, including robust efforts to report and demonstrate tangible and meaningful outcomes of biomedical research and clinical care. These services represent a transformative direction that can be emulated by other biomedical and research libraries.
