Survey instrument used in Survey of Academic Library Streaming Video Revisited, 2015
Explains the urgent need for libraries to engage in preservation of irreplaceable content on VHS and other obsolete video formats in their collections, and presents a database of titles for which due diligence as required by Section 108 of US Copyright has already been completed.
In spring 2013, the presenters developed a survey on academic library streaming video and distributed it broadly through various discussion and mailing lists.
This is the first large-scale and most comprehensive effort to date to collect data on streaming video funding, licensing, acquisition, and hosting in academic libraries. Its results will provide benchmark data for future explorations of this rapidly expanding approach to video in academic libraries.
Streaming video is becoming a common occurrence on many campuses today. Its fast growth is due in part to the steady growth of online classes and programs. Technology has also played a role in this growth as alternatives for ingesting and accessing content have expanded. Multiple options are now available including in-house approaches, cloud storage, and third party vendors.
This survey collected data on how academic institutions address the day-to-day operations related to streaming video as well as perceived directions for future action.
Survey questions addressed selection and acquisition of video in both hard copy and streaming formats, funding for acquisitions, current and planned hosting interfaces, cataloging and access, and current practice and policy on digitization of hard copy titles for streaming. This session reviews the instrument used, and provides a preliminary look at some of the key data collected.
Streaming video has been an option for academic libraries for nearly a decade. What is the state of streaming video in academic libraries today? How are these libraries acquiring streaming videos? Who makes acquisition decisions? How much staff time does supporting streaming video require?
Extreme events, a type of collective behavior in complex networked dynamical systems, often can have catastrophic consequences. To develop effective strategies to control extreme events is of fundamental importance and practical interest. Utilizing transportation dynamics on complex networks as a prototypical setting, we find that making the network “mobile” can effectively suppress extreme events. A striking, resonance-like phenomenon is uncovered, where an optimal degree of mobility exists for which the probability of extreme events is minimized. We derive an analytic theory to understand the mechanism of control at a detailed and quantitative level, and validate the theory numerically. Implications of our finding to current areas such as cybersecurity are discussed.
