OA in the Library Collection: The Challenges of Identifying and Maintaining Open Access Resources     

Chris Bulock  Nathan Hosburgh  Sanjeet Mann 《期刊图书馆员》2015,68(1-4):79-86

While librarians, researchers, and the general public have embraced the concept of Open Access (OA), librarians still have a difficult time managing OA resources. To find out why, Bulock and Hosburgh surveyed librarians about their experiences managing OA resources and the strengths and weaknesses of management systems. At this session, they shared survey results, reflected on OA workflows at their own libraries, and updated audience members on relevant standards and initiatives. Survey respondents reported challenges related to hybrid OA, inaccurate metadata, and inconsistent communication along the serials supply chain. Recommended solutions included the creation of consistent, centralized article-level metadata and the development of OA collection development principles for libraries.  相似文献   

Development of an Augmented Reality Game to Teach Abstract Concepts in Food Chemistry          下载免费PDF全文

One of the most pressing issues for many land grant institutions is the ever increasing cost to build and operate wet chemistry laboratories. A partial solution is to develop computer‐based teaching modules that take advantage of animation, web‐based or off‐campus learning experiences directed at engaging students’ creative experiences. We used the learning objectives of one of the most difficult topics in food chemistry, enzyme kinetics, to test this concept. Students are apprehensive of this subject and often criticize the staid instructional methods typically used in teaching this material. As a result, students do not acquire a useful background in this important subject. To rectify these issues, we developed an interactive augmented reality application to teach the basic concepts of enzyme kinetics in the context of an interactive search that took students to several locations on campus where they were able to gather raw materials and view videos that taught the basics of enzyme kinetics as applied to the production of high fructose corn syrup (HFCS). The students needed this background to prepare for a mock interview with an HFCS manufacturer. Students and instructors alike found the game to be preferable to sitting in a classroom listening to, or giving, a PowerPoint presentation. We feel that this use of gaming technology to teach difficult, abstract concepts may be a breakthrough in food science education and help alleviate the drain on administrative budgets from multiple wet labs.  相似文献   

Manipulating particle trajectories with phase-control in surface acoustic wave microfluidics     

Orloff ND  Dennis JR  Cecchini M  Schonbrun E  Rocas E  Wang Y  Novotny D  Simmonds RW  Moreland J  Takeuchi I  Booth JC 《Biomicrofluidics》2011,5(4):44107-441079

We present a 91 MHz surface acoustic wave resonator with integrated microfluidics that includes a flow focus, an expansion region, and a binning region in order to manipulate particle trajectories. We demonstrate the ability to change the position of the acoustic nodes by varying the electronic phase of one of the transducers relative to the other in a pseudo-static manner. The measurements were performed at room temperature with 3 μm diameter latex beads dispersed in a water-based solution. We demonstrate the dependence of nodal position on pseudo-static phase and show simultaneous control of 9 bead streams with spatial control of −0.058 μm/deg ± 0.001 μm/deg. As a consequence of changing the position of bead streams perpendicular to their flow direction, we also show that the integrated acoustic-microfluidic device can be used to change the trajectory of a bead stream towards a selected bin with an angular control of 0.008 deg/deg ± 0.000(2) deg/deg.  相似文献   

A comparative study of baseball bat performance   总被引：2，自引：2，他引：0  

Alan M. Nathan  Joseph J. Crisco  R. M. Greenwald  D. A. Russell  Lloyd V. Smith 《Sports Engineering》2011,13(4):153-162

The results of a comparative study of five aluminum and one wood baseball bats are presented. The study includes an analysis of field data, high-speed laboratory testing, and modal analysis. It is found that field performance is strongly correlated with the ball–bat coefficient of restitution (BBCOR) and only weakly correlated with other parameters of the bat, suggesting that the BBCOR is the primary feature of a bat that determines its field performance. It is further found that the instantaneous rotation axis of the bat at the moment of impact is very close to the knob of the bat and that the rotational velocity varies inversely with the moment of inertia of the bat about the knob. A swing speed formula is derived from the field data and the limits of its validity are discussed. The field and laboratory measurements of the collision efficiency are generally in good agreement, as expected on theoretical grounds. Finally, the BBCOR is strongly correlated with the frequency of the lowest hoop mode of the hollow bats, as predicted by models of the trampoline effect.  相似文献   

Has Bartel resolved the gamer’s dilemma?     

Morgan Luck  Nathan Ellerby 《Ethics and Information Technology》2013,15(3):229-233

In this paper we consider whether Christopher Bartel has resolved the gamer’s dilemma. The gamer’s dilemma highlights a discrepancy in our moral judgements about the permissibility of performing certain actions in computer games. Many gamers have the intuition that virtual murder is permissible in computer games, whereas virtual paedophilia is not. Yet finding a relevant moral distinction to ground such intuitions can be difficult. Bartel suggests a relevant moral distinction may turn on the notion that virtual paedophilia harms women in a way that virtual murder does not. We argue that this distinction is only in a position to provide a partial solution to the dilemma.  相似文献

Infantile Amnesia: Through a Glass Darkly     

Nora Newcombe  Nathan A. Fox 《Child development》1994,65(1):31-40

Memory for former preschool classmates was examined in 9-and 10-year-old children using measures of both explicit and implicit memory. Yes-no recognition of faces was at low levels but was significantly above chance. Skin conductance data showed similarly low but above-chance differentiation between classmates and controls. A median split of children based on their recognition memory scores showed that children with little evidence of explicit memory for classmates were as likely to show differential skin conductance responding to faces of former classmates as were children with higher recognition scores. Infantile amnesia, like the clinical syndrome for which it is named, may not always involve complete loss of encoded information.  相似文献   

How Do Academic Disciplines Use PowerPoint?     

Nathan Garrett 《Innovative Higher Education》2016,41(5):365-380

How do academic disciplines use PowerPoint? This project analyzed PowerPoint files created by an academic publisher to supplement textbooks. An automated analysis of 30,263 files revealed clear differences by disciplines. Single-paradigm “hard” disciplines used less complex writing but had more words than multi-paradigm “soft” disciplines. The “hard” disciplines also used a greater number of small graphics and fewer large ones. Disciplines identified by students as being more effective users of PowerPoint used larger images and more complex sentences than disciplines identified as being less effective in this regard. This investigation suggests that PowerPoint best practices are not universal and that we need to account for disciplinary differences when creating presentation guidelines.  相似文献
