Instructor Use of Educational Streaming Video Resources

Although a substantial majority of academic libraries now provide streaming video, the literature contains few studies which focus on how such resources are used. This article presents the results of a qualitative research study consisting of in-depth interviews with 18 instructors who use of one category of streaming video resources, educational videos, which are important because they are sold a higher price than most individuals can afford, and thus are typically only available to instructors through the library. The study's main findings are that instructors think educational streaming video resources compare favorably to commercial and non-streaming alternatives in most respects and use them whenever possible, that the primary benefit of these resources is to facilitate better use of limited class time by enabling instructors to assign videos as outside-of-class viewing, and that the library is not the primary means instructors use to discover new educational streaming video resources. Additional insights are provided into factors that academic libraries should consider when deciding which resources to invest in, which acquisition models to pursue, and what marketing strategies to employ to ensure maximum usage.     

Power Struggles,Regulation and Responsibility

This article explores the relationship between the British Board of Film Classification (BBFC) and government during the implementation of the Video Recordings Act (VRA). It considers the public Parliamentary debates about the VRA, and places them alongside private correspondence between the Home Office and the BBFC, and internal BBFC material from the recently catalogued James Ferman papers held at the BFI. As well as exploring the introduction of the VRA, this article also aims to briefly consider its implications for the BBFC, how they set about interpreting and implementing its stringent recommendations and how this impacted upon the organisational working practices of the Board. While the VRA was without doubt one of the most significant pieces of legislation within the history of film regulation in Britain, the time is ripe for its reappraisal and with it a re-evaluation of the role played by the BBFC in securing statutory regulatory powers.     

视频组播分层解决方案的研究

High-entropy-alloy nanoparticles with 21 ultra-mixed elements for efficient photothermal conversionOA

Multi-metallic nanoparticles have been proven to be an efficient photothermal conversion material, for which the optical absorption can be broadened through the interband transitions(IBTs), but it remains a challenge due to the strong immiscibility among the repelling combinations. Here, assisted by an extremely high evaporation temperature, ultra-fast cooling and vapor-pressure strategy, the arc-discharged plasma method was employed to synthesize ultra-mixed multi-metallic nanoparticles compose...
