Abstract

In an economic climate when colleges can no longer presume that legislators see institutions of higher learning as tacit public goods, institutions around the country are facing budget cuts. This article presents a case study of the experience of a mid-sized public state university and its Library in a budget crisis undergoing a university-wide program prioritization process. The authors review the process of writing three reports on the Library’s value, along with the approach to engaging staff in the process including a retreat. This article raises questions about what every library should consider assessing and provide tools for libraries navigating similar terrain.  相似文献   

Perception of kinematic characteristics of tennis strokes for anticipating stroke type and direction     

Shim J  Les Carlton G  Kwon YH 《Research quarterly for exercise and sport》2006,77(3):326-339

The purpose of this study was to determine the sources of visual information used by highly skilled tennis players in anticipating their opponent's shots. In Experiment 1, motion analysis of the strokes showed that the relative motion between the racquet and forearm was different between the ground strokes and lobs, but there were no reliable kinematic differences when shot direction was varied. In Experiment 2, 12 skilled tennis players observed the opponent hitting strokes in a normal video or in a point-light display with different segments occluded. Players' anticipation accuracy was not degraded by the use of the point-light display. Occluding the racquet and forearm significantly reduced the participant's ability to determine the type of stroke produced.  相似文献   

Effects of light refraction on the accuracy of camera calibration and reconstruction in underwater motion analysis   总被引：1，自引：0，他引：1  

Kwon YH  Casebolt JB 《Sports biomechanics / International Society of Biomechanics in Sports》2006,5(2):315-340

One of the most serious obstacles to accurate quantification of the underwater motion of a swimmer's body is image deformation caused by refraction. Refraction occurs at the water-air interface plane (glass) owing to the density difference. Camera calibration-reconstruction algorithms commonly used in aquatic research do not have the capability to correct this refraction-induced nonlinear image deformation and produce large reconstruction errors. The aim of this paper is to provide a thorough review of: the nature of the refraction-induced image deformation and its behaviour in underwater object-space plane reconstruction; the intrinsic shortcomings of the Direct Linear Transformation (DLT) method in underwater motion analysis; experimental conditions that interact with refraction; and alternative algorithms and strategies that can be used to improve the calibration-reconstruction accuracy. Although it is impossible to remove the refraction error completely in conventional camera calibration-reconstruction methods, it is possible to improve the accuracy to some extent by manipulating experimental conditions or calibration frame characteristics. Alternative algorithms, such as the localized DLT and the double-plane method are also available for error reduction. The ultimate solution for the refraction problem is to develop underwater camera calibration and reconstruction algorithms that have the capability to correct refraction.  相似文献   

Repeat Consumption of Media Goods: Examining Factors Affecting Repeat Theatrical Viewing of Movies     

Byeng-Hee Chang  Sang-Hyun Nam  Hun Kim 《Journal of Media Economics》2016,29(4):167-180

This study explored the factors affecting repeat theatrical viewing of movies. Integrating content, social influence, and access/competition variables, the analysis reveals that the drivers of theatrical repeat viewing are different from those for box office performance. For example, the effects of genre, transmedia content, and audience review were significant only for the latter and factors such as movie length, critics’ review, and level of news coverage actually played a negative role in the repeat consumption.  相似文献   

Social IEP Objectives, Teacher Talk, and Peer Interaction in Inclusive and Segregated Preschool Settings     

Kyong-Ah Kwon  James Elicker  Susan Kontos 《Early Childhood Education Journal》2011,39(4):267-277

The purpose of this study was to examine: (a) the role of teacher talk in promoting peer interaction, (b) the adequacy of social IEP objectives to reflect children’s social functioning and guide provision of teacher talk, and (c) differences in children’s peer interaction and teacher talk in inclusive and segregated settings. Thirty children with disabilities and their teachers participated. Overall, we observed low rates of teacher talk thought to support peer interaction; however, when teachers verbally facilitated peer interaction, children were observed interacting more frequently with peers. Children’s social IEPs accurately reflected their current level of social functioning. However, the social IEPs appeared to fail to influence teacher intervention. Finally, children with disabilities in inclusive settings interacted with peers more than children in segregated settings, even though there was no significant difference in amount of teacher talk in the two settings.  相似文献   

USING AN ENHANCED CONFLICT MAP IN THE CLASSROOM (PHOTOELECTRIC EFFECT) BASED ON LAKATOSIAN HEURISTIC PRINCIPLE STRATEGIES     

Jun-Young Oh 《International Journal of Science and Mathematics Education》2011,9(5):1135-1166

Researchers have shown that most students resist changes to their core beliefs by offering auxiliary hypotheses at the first sign of the development of conceptual change. Studies have viewed student reaction to discrepant events as an important clue in helping researchers understand not only the structure of alternative concepts (Niaz, Science & Education, 7(2):107 – 127, 1998) but also the nature of scientific concepts. The main objectives of this research were the following: (a) to consider prudently the conflict map of Tsai (International Journal of Science Education, 22(3):285 – 302, 2000); (b) to initiate and develop an enhanced conflict map based on Lakatosian ethodology, which could help science teachers and students resolve conflicts that occur in the explanation of natural phenomena; (c) to examine the effectiveness of the enhanced conflict map; and (d) to discuss these implications in science education. Specifically, this study used two freshman classes from the Department of Electronics and one class of Astronomy majors from C. National University, South Korea, to investigate how scientific concepts change after selecting the modern physics field (Photoelectric effect), which is included in the Physics and Astronomy courses. Modern physics has led to the so-called Lakatosian heuristic principle or methodology, a useful framework that includes scientific philosophy and science history as study strategies. “Enhanced conflict maps” are suggested for use to consistently show all the study processes.  相似文献

An efficient method for tracing planar implicit curves   总被引：1，自引：0，他引：1  

YU Zheng-sheng CAI Yao-zhi OH Min-jae KIM Tae-wan PENG Qun-sheng 《浙江大学学报(A卷英文版)》2006,7(7):1115-1123

INTRODUCTION Tracing a planar implicit curve f(x, y)=0 on a rectangular region [xl, xr]×[yb, yt] is of great interest in Computer-Aided Design and Computer Graphics. While parametric curves are easy to plot, plotting implicit curves is a challenging problem. Planar im- plicit curve plotting method can be classified into two categories (Shou et al., 2005; Martin et al., 2002; Lopes et al., 2002). In the first category are subdivi- sion methods (Shou et al., 2005; Martin et al., 2002) …  相似文献

Collagen-based brain microvasculature model in vitro using three-dimensional printed template     

Jeong Ah Kim  Hong Nam Kim  Sun-Kyoung Im  Seok Chung  Ji Yoon Kang  Nakwon Choi 《Biomicrofluidics》2015,9(2)

We present an engineered three-dimensional (3D) in vitro brain microvasculature system embedded within the bulk of a collagen matrix. To create a hydrogel template for the functional brain microvascular structure, we fabricated an array of microchannels made of collagen I using microneedles and a 3D printed frame. By culturing mouse brain endothelial cells (bEnd.3) on the luminal surface of cylindrical collagen microchannels, we reconstructed an array of brain microvasculature in vitro with circular cross-sections. We characterized the barrier function of our brain microvasculature by measuring transendothelial permeability of 40 kDa fluorescein isothiocyanate-dextran (Stoke''s radius of ∼4.5 nm), based on an analytical model. The transendothelial permeability decreased significantly over 3 weeks of culture. We also present the disruption of the barrier function with a hyperosmotic mannitol as well as a subsequent recovery over 4 days. Our brain microvasculature model in vitro, consisting of system-in-hydrogel combined with the widely emerging 3D printing technique, can serve as a useful tool not only for fundamental studies associated with blood-brain barrier in physiological and pathological settings but also for pharmaceutical applications.  相似文献
