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   

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   

Numerical simulation on the opto-electro-kinetic patterning for rapid concentration of particles in a microchannel     

Dong Kim  Jaesool Shim  Han-Sheng Chuang  Kyung Chun Kim 《Biomicrofluidics》2015,9(3)

This paper presents a mathematical model for laser-induced rapid electro-kinetic patterning (REP) to elucidate the mechanism for concentrating particles in a microchannel non-destructively and non-invasively. COMSOL^®(v4.2a) multiphysics software was used to examine the effect of a variety of parameters on the focusing performance of the REP. A mathematical model of the REP was developed based on the AC electrothermal flow (ACET) equations, the dielectrophoresis (DEP) equation, the energy balance equation, the Navier-Stokes equation, and the concentration-distribution equation. The medium was assumed to be a diluted solute, and different electric potentials and laser illumination were applied to the desired place. Gold (Au) electrodes were used at the top and bottom of a microchannel. For model validation, the simulation results were compared with the experimental data. The results revealed the formation of a toroidal microvortex via the ACET effect, which was generated due to laser illumination and joule-heating in the area of interest. In addition, under some conditions, such as the frequency of AC, the DEP velocity, and the particle size, the ACET force enhances and compresses resulting in the concentration of particles. The conditions of the DEP velocity and the ACET velocity are presented in detail with a comparison of the experimental results.  相似文献   

What Motivates Parents to Mediate Children’s Use of Smartphones? An Application of the Theory of Planned Behavior     

Wonsun Shin  Hye Kyung Kim 《广播与电子媒介杂志》2019,63(1):144-159

Applying the Theory of Planned Behavior (TPB), this study examines parents’ attitudes, social norms, self-efficacy, and intentions regarding parental mediation of children’s smartphone use. A survey conducted with parents of young smartphone users aged 10–17 shows that parents tend to perceive discussion-based active mediation to be more desirable, as compared to rule-making restrictive mediation. Findings also indicate that the extent to which parents believe that they have control over their parental mediation practices plays an important role in forming positive intentions to practice parental mediation, regardless of the mediation domain.  相似文献

Opinion Versus Knowledge: The Influence of Testimony Format on Children’s Judgments in Morally Relevant Contexts     

Jee Young Noh  Laura Marie Elenbaas  Kyung Ja Park  Young Sun Chung  Melanie Killen 《Early education and development》2017,28(2):240-254

Research Findings: To test children’s use of testimony of others, 3 – 9 years (N = 227) made judgments about a potential peer transgression in which the intentions of the protagonist were ambiguous, after hearing two different forms of testimony. The 2 forms of testimony were (a) opposing opinion-based testimony from an adult authority versus a peer consensus group and (b) knowledge-based testimony (eyewitness testimony) that was counter to the participants’ initial judgments. Findings revealed that when testimony was presented in an opinion-based format, children were likely to side with the opinion that reflected their own interpretation of the peer encounter, regardless of whether the opinion came from a peer consensus or an adult authority. However, when knowledge-based testimony was introduced in support of the opposite of children’s initial interpretation of the ambiguous peer encounter, children most often changed their initial judgment to align with the new testimony. That is, children used knowledge-based testimony but not opinion-based testimony to evaluate a potential transgression. Practice or Policy: These findings demonstrate that the way in which testimony is delivered to children has a direct influence on their decision making about peer interactions and has relevance for teacher–student discourse in the classroom.  相似文献   

Multi-layer self-organizing polynomial neural networks and their development with the use of genetic algorithms   总被引：1，自引：0，他引：1  

Sung-Kwun Oh 《Journal of The Franklin Institute》2006,343(2):125-136

In this paper, we introduce a new architecture of genetic algorithms (GA)-based self-organizing polynomial neural networks (SOPNN) and discuss a comprehensive design methodology. Let us recall that the design of the “conventional” PNNs uses an extended group method of data handling (GMDH) and exploits polynomials (such as linear, quadratic, and modified quadratic functions) as well as considers a fixed number of input nodes (as being selected in advance by a network designer) at polynomial neurons (or nodes) located in each layer. The proposed GA-based SOPNN gives rise to a structurally optimized structure and comes with a substantial level of flexibility in comparison to the one we encounter in conventional PNNs. The design procedure applied in the construction of each layer of a PNN deals with its structural optimization involving the selection of preferred nodes (or PNs) with specific local characteristics (such as the number of input variables, the order of the polynomial, and a collection of the specific subset of input variables) and addresses specific aspects of parametric optimization. An aggregate performance index with a weighting factor is proposed in order to achieve a sound balance between approximation and generalization (predictive) abilities of the network. To evaluate the performance of the GA-based SOPNN, the model is experimented with using chaotic time series data. A comparative analysis reveals that the proposed GA-based SOPNN exhibits higher accuracy and superb predictive capability in comparison to some previous models available in the literature.  相似文献
