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.
Survey instrument used in Survey of Academic Library Streaming Video Revisited, 2015
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?
Neural progenitor cells (NPCs) derived from human pluripotent stem cells (hPSCs) are a multipotent cell population that is capable of nearly indefinite expansion and subsequent differentiation into the various neuronal and supporting cell types that comprise the CNS. However, current protocols for differentiating NPCs toward neuronal lineages result in a mixture of neurons from various regions of the CNS. In this study, we determined that endogenous WNT signaling is a primary contributor to the heterogeneity observed in NPC cultures and neuronal differentiation. Furthermore, exogenous manipulation of WNT signaling during neural differentiation, through either activation or inhibition, reduces this heterogeneity in NPC cultures, thereby promoting the formation of regionally homogeneous NPC and neuronal cultures. The ability to manipulate WNT signaling to generate regionally specific NPCs and neurons will be useful for studying human neural development and will greatly enhance the translational potential of hPSCs for neural-related therapies.
