The essay seeks to effectively identify and compare strategies used by libraries throughout the United States. Beyond analyzing the structure of author funds, the essay explores the value of such programs in promoting OA values of not only free to read, but free to publish. Asking the question, are libraries best suited to expend resources by paying publishing fees and does it achieve its purpose of promoting OA journals? Overall, the essay outlines the role of OA in expanding the potential for libraries to develop its role in scholarly publishing; particularly by promoting researchers’ publications in OA journals using author funds.
PDA involves the inclusion of bibliographic records to the catalog for titles the library does not own and permits the patron an opportunity to initiate a purchase. Beyond the practical implications of managing costs and liberating staff time, the PDA model provides patrons easier and quicker access to the widest range of information possible. The service model of populating a collection to protect against the possibility of patrons requiring access is increasingly unsustainable. Although not without its challenges, allowing the patron to provide a collaborative role with librarians in developing a collection serves to manage costs and streamlines the process of creating a collection which best addresses the needs of a constituency.
Accessibility is increasingly used as a metric when evaluating changes to public transport systems. Transit travel times contain variation depending on when one departs relative to when a transit vehicle arrives, and how well transfers are coordinated given a particular timetable. In addition, there is necessarily uncertainty in the value of the accessibility metric during sketch planning processes, due to scenarios which are underspecified because detailed schedule information is not yet available. This article presents a method to extend the concept of "reliable" accessibility to transit to address the first issue, and create confidence intervals and hypothesis tests to address the second.
There is a need for indicators of transportation-land use system quality that are understandable to a wide range of stakeholders, and which can provide immediate feedback on the quality of interactively designed scenarios. Location-based accessibility indicators are promising candidates, but indicator values can vary strongly depending on time of day and transfer wait times. Capturing this variation increases complexity, slowing down calculations. We present new methods for rapid yet rigorous computation of accessibility metrics, allowing immediate feedback during early-stage transit planning, while being rigorous enough for final analyses. Our approach is statistical, characterizing the uncertainty and variability in accessibility metrics due to differences in departure time and headway-based scenario specification. The analysis is carried out on a detailed multi-modal network model including both public transportation and streets. Land use data are represented at high resolution. These methods have been implemented as open-source software running on commodity cloud infrastructure. Networks are constructed from standard open data sources, and scenarios are built in a map-based web interface. We conclude with a case study, describing how these methods were applied in a long-term transportation planning process for metropolitan Amsterdam.
