Modeling Time-To-Trigger In Library Demand-Driven Acquisitions Via Survival Analysis, Zhehan Jiang, Sarah Fitzgerald, Kevin W. Walker
Modeling Time-To-Trigger In Library Demand-Driven Acquisitions Via Survival Analysis, Zhehan Jiang, Sarah Fitzgerald, Kevin W. Walker
University Libraries Publication Series
Conventional statistical methods (e.g. logistics regression, decision tree, etc.) have been used to analyze library demand-driven acquisitions (DDA) data. However, these methods are not well-suited to predict when acquisitions will be triggered or how long e-books will remain unused. Survival analysis, a statistical method commonly used in clinical research and medical trials, was employed to predict the time-to-trigger for DDA purchases within the context of a large research university library. By predicting which e-books will be triggered (i.e., purchased), as well as the time to trigger occurrence, the method tested in this study provides libraries a deeper understanding of factors …
Flipping An Academic Library Collection: A Path To A Global Open Scholarly Commons, Christine N. Turner, Marilyn S. Billings
Flipping An Academic Library Collection: A Path To A Global Open Scholarly Commons, Christine N. Turner, Marilyn S. Billings

In late 2017, the University of Massachusetts Amherst Libraries participated in the David Lewis and Michael Roy “2.5% Commitment and Open Data Collection Tool Project.” This exercise provided a benchmark of collection and infrastructure investments to date, and it brought into focus the opportunity to articulate the Libraries’ intentions for their collections going forward. The UMass Amherst Libraries provide a case study of an academic library collection that is pivoting from materials produced by proprietary publishers to a mix of investments in unique and special collections; open access publishing, content and infrastructure; and materials published through traditional channels.
Seascapes And Fresh Water Management In Rural Greece: The Case Of The Mani Peninsula, 1261–1821 Ce, Rebecca M. Seifried
Seascapes And Fresh Water Management In Rural Greece: The Case Of The Mani Peninsula, 1261–1821 Ce, Rebecca M. Seifried
University Libraries Publication Series
The Mani peninsula is a semi-arid landscape with few natural sources of fresh water, yet it supported a dense population during the Late Byzantine and Ottoman periods. This paper reviews the archaeological and historical evidence for water-management practices in Mani, concentrating on its domestic-scale hydraulic infrastructure (cisterns and saltpans) and the ports and harbours along its coasts. The data point to a critical shift in household-level social organization at the turn of the 18th century, underscoring the fact that people living in supposedly ‘peripheral’ regions like Mani nevertheless engaged in far-reaching networks of contact and exchange.

Higher Education Publication And Institutional And National Diversity, Sarah Fitzgerald, Zhehan Jiang
Higher Education Publication And Institutional And National Diversity, Sarah Fitzgerald, Zhehan Jiang
University Libraries Publication Series
Educational scholarship is used by practitioners, policy makers, and scholars to shape educational practices. Since education takes place across the globe and incorporates students from a wide variety of backgrounds, educational scholarship should incorporate diverse perspectives. This study examines how institutionally and internationally diverse five leading journals of higher education are. Twelve years of publications are examined to determine the level of diversity among top higher education journals and compare diversity among these publications over time. Maps displaying the distribution of authors across the world are provided to illustrate the findings that higher education publication in the leading journals tends …

Nirds Unite: Building A Community Of Institutional Repository Practitioners In The Northeast, Eleni Castro, Erin Jerome, Colin Lukens, Mikki Simon Macdonald, Lisa A. Palmer

The idea for “Northeast Institutional Repository Day” (NIRD) was conceived by a group of five repository librarians in the northeast. The organizers sent out a pre-conference online survey to the IR community in November 2018 to see if fellow repository practitioners had an interest in attending and/or participating in such a day and the response was a resounding, “Yes!” The survey results suggested that building a stronger regional network of repository managers would foster meaningful discussions on the merits and effectiveness of IRs.

An Exploratory Spatial Analysis Of The Churches In The Southern Mani Peninsula, Greece, Rebecca M. Seifried, Tuna Kalaycı
An Exploratory Spatial Analysis Of The Churches In The Southern Mani Peninsula, Greece, Rebecca M. Seifried, Tuna Kalaycı
University Libraries Publication Series
The Mani Peninsula is home to hundreds of Orthodox Christian churches that were built within the last millennium. As in other parts of the Eastern Mediterranean countryside, the topological relationship between churches and settlements is a critical factor in understanding the significance of the sacred landscape. Many churches are situated in the central part of a village or on its very edge, but others – what are referred to as “outlying churches” or exokklisia – are built at great distances away. In this paper, we make the first attempt to assess the spatial relationship between the spaces where people worshipped …
Promoting Institutional Repositories Via Visualizations - A Changepoint Study, Zhehan Jiang, Sarah Fitzgerald
Promoting Institutional Repositories Via Visualizations - A Changepoint Study, Zhehan Jiang, Sarah Fitzgerald
University Libraries Publication Series
This paper examines whether implementing visualizations on an institutional repository webpage increases traffic on the site. Two methods for creating visualizations to attract faculty and student interest were employed. The first is a map displaying usage of institutional repository content from around the world. This map uses Tableau software to display Google Analytics data. The second method is a text mining tool allowing users to generate wordclouds from dissertation and thesis abstracts according to discipline and year of publication. The wordcloud uses R programming language, the Shiny software package, and a text mining package called tm. Change in the number …
