Using Food Science Demonstrations to Engage Students of All Ages in Science,Technology, Engineering,and Mathematics (STEM)

Abstract: The overarching goal of the Science, Technology, Engineering, and Mathematics (STEM) Education Initiative is to foster effective STEM teaching and learning throughout the educational system at the local, state, and national levels, thereby producing science literate citizens and a capable STEM workforce. To contribute to achieving this goal, we have assembled six food science demonstrations for use at all educational levels and have presented these lessons to students at the elementary through higher education levels. The focus of this article is to share these food science demonstrations and our experiences using them so that others can use them for engaging students in STEM disciplines, through food science, at any educational level. Featured demonstrations include: (1) liquid nitrogen ice cream: a matter of changing phases, (2) seeing our senses work together, (3) whipping up the cream, (4) milk versus dark: what is the difference?, (5) counting calories by burning them, and (6) culinary spherification: the wonders of cross‐linking. Overall, our experience with using these demonstrations has been very positive. Students appear engaged in the learning process and love to consume the demonstration end products. Downloadable handouts containing demonstration details for each demonstration are available as supporting information.     

When the Pilot Is Over: Picking the Program and Making It Stick,Purchase on Demand at the University of South Florida

In 2008 the Interlibrary Loan department of the University of South Florida, Tampa, began a Purchase on Demand program, using interlibrary loan requests to supplement Collection Development practices. After three years the program was analyzed for effectiveness and compared to other programs currently in operation. To achieve a complete evaluation, interlibrary loan patrons were surveyed on their awareness and use of the Purchase on Demand program. This article combines the analysis of USF's program with recommendations gained through administration and evaluation of Purchase on Demand.     

The Florida State Libraries Resource Sharing Initiative: Did the Predictions Pan Out?

This article revisits discussion from “The Florida State Libraries Resource Sharing Initiative: Unity Among a Disparate Group” (Schmidt & Smith, 2012) on the implementation of a new resource sharing program within the Florida State University Libraries called UBorrow. The program and its effects are assessed after 2 years with comparison to the project launch's original predictions.     

Radical Relocation: Adapting Print Collections to an E-Centric World

With the advent of e-journal preservation projects and publisher digitization of journal backfiles, academic libraries have begun to move their corresponding print volumes of these titles to storage to avoid duplication and save space. This article examines the supporting justifications, outreach mechanisms, and logistical procedures undertaken at American University Library to relocate the entire bound journal collection to offsite storage in order to address severe physical space constraints and to support patron use of and preference for electronic journal content. In addition, the article presents preliminary data regarding the use of bound volumes sent to storage and an overall analysis of this transformational project.     

ISSUES IN COUNSELING OLDER PEOPLE

This paper reports a thorough investigation of reading habits and activities which may require skills used in prose recall tasks as they occur in the everyday lives of adults. Over the space of five weeks, fifty‐four participants (18 young, aged 18‐32; 18 middle, aged 40‐54; 18 older, aged over 62) kept structured diaries in which they indicated how they spent their time, as well as the specific materials they had read and how long they had spent reading each item. Analyses were performed on each of 23 reading variables and 20 activity variables. Part I of this paper considers whether there were age and vocabulary differences in activities. Results indicate that while such differences exist, primarily in the amount of time spent reading, everyday activities and reading habits were also related to the requirements of daily life‐‐school, employment, retirement. Part II uses a cluster analysis of the data to demonstrate that the patterning of everyday activities was influenced more by current schooling and career factors than by the age and vocabulary level of the participants. Part II also considers the ecological validity of prose recall studies by examining the frequency of activities similar to laboratory‐style prose recall tasks and finds that such activities have a very low incidence in the everyday lives of adults.     

论京剧声腔源于陕西

关于京剧声腔的起源,过去一般认为是二黄调和西皮调在北京合体而成,本文认为这个观点缺乏事实依据,京剧声腔的产地不是安徽或湖北,而是陕西,陕西历史上存在前后两个秦腔,前秦腔即陕西二黄(又称汉调二黄,今称陕西汉剧)早在乾隆55年四大徽班进京之前已广泛流传于北京和东南各地,四大徽班中的三庆班,春台班进京所唱的腔调主要是前秦腔;细考京剧与陕西二黄的声腔,二者确实同类.京剧的声腔是从陕西二黄的母体中孕育出来的.
