Analyzing Information Needs of Elderly People: A Survey in Chinese Rural Community  [PDF]
Chunfang Zou, Ping Zhou
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.29019

A survey about the information needs of elderly people could find out the information required to address the needs of the aged in a community. Analyzing data collected from 600 elderly people through field investigation with a questionnaire in a rural community in central China, the results show that the preferred information format of the majority of aged people is audio and/or visual information product, especially audio product. Most of the aged people stated that they were in need of healthy and medical non-educational audio information products. The survey maybe lead to improved and expanded information services for respondents who are short of such services, including Public broadcasting services, extending the audiovisual collection, loaning audiovisuals, religious faith audiovisuals and others providing needed information to them. In summary, this paper assembles views on what the elderly people currently need to be helped by both practitioners and researchers in the elderly people services domain.

Group Creativity in Learning Context: Understanding in a Social-Cultural Framework and Methodology  [PDF]
Chunfang Zhou, Lingling Luo
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.34062
Abstract: Recent studies have emphasized group creativity as a social-cultural conception, but they lack a focus on the relationship between group creativity and knowledge creation. This paper aims to build a framework for group creativity in a learning context which includes both theoretical understanding and empirical methodology. Thus, a literature review is led by the following questions: How has creativity theory been developed from individual to group level? From a social-cultural perspective, how can group creativity, knowledge creation, and their relationship be understood? And what methods have been employed to study group creativity? As the review demonstrates, creativity theory has been driven by new insights from recent sociology studies. Three focuses have been shaped from group creativity studies: 1) group creativity in context, 2) group-level creative synergy, and 3) strategies for developing group creativity. Individual knowledge is a potential resource for group creativity, and group creativity could be a driver of knowledge creation. Empirically, group creativity can be examined through both qualitative and quantitative approaches, which also calls for a creative combination of methodologies in future studies.
An Evanescent Light Wave Cannot Possess a Transverse Spin  [PDF]
Chunfang Li, Yunlong Zhang
Journal of Modern Physics (JMP) , 2019, DOI: 10.4236/jmp.2019.104031
Abstract: It is pointed out that the evanescent light wave occurring at total reflection does not possess a transverse spin angular momentum as Bliokh, Bekshaev, and Nori claimed recently in (2014) Nature Communications, 5,3300. This is not only because of the nonlocality of the photon spin but also because the evanescent wave is such a state whose angular momentum cannot be separated into spin and orbital parts.

Journal on Efficiency and Responsibility in Education and Science , 2012,
Abstract: Recent studies have emphasized the necessity of educating creative engineers. This paper aims to provide a literature review by answering what strategies can be applied to develop creativity in engineering education. As the literature demonstrates, creativity has been studied by a diversity of perspectives such as psychology, social psychology and sociology. Studies on engineering creativity indicate the importance of problem-solving skills for engineers. For developing creativity, strategies such as using thinking tools, learning by solving problems and building learning environment conductive to creativity have been suggested in engineering education. Problem-Based Learning (PBL) is a good example of fostering creative engineers, so characteristics of PBL, learning cycle in PBL and methods for enhancing group dynamics in PBL are discussed in this paper.
Learning Engineering Knowledge and Creativity by Solving Projects
Chunfang Zhou
International Journal of Engineering Pedagogy , 2012, DOI: 10.3991/ijep.v2i1.1873
Abstract: Recent studies have argued the increasing complexity of engineering practice brings challenges to engineers. Creativity has been thought as one necessary element in engineering education. And to let students work with project work has been regarded as a good strategy of developing creativity. However, the literature shows studies on engineering education, most previous efforts take a departure of psychological perspective to discuss developing creative skills through project work; there is a lack of discussion on how project work supports achieving new knowledge and creativity in a social theory framework. Therefore, this paper aims to answer this lack and provide a literature review by focusing on three questions: 1) Which kinds of knowledge are needed for engineering students? 2) What are relationships between knowledge, learning and creativity? And 3) why does a solving project context support creativity and learning? Based on answering the three questions, the literature review underpins the needs of developing creativity in engineering education and strengths of solving project context in stimulating creativity and learning. So this paper contributes to future studies and practical strategies of fostering creative engineers.
Extension matrix representation theory of light beams and the Beauregard effect
Chunfang Li
Physics , 2007,
Abstract: It is shown that a light beam in free space is representable by an integral over a vectorial angular spectrum that is expressed in terms of an extension matrix, which describes the vectorial nature of the beam. A symmetry axis of the extension matrix is identified. When it is neither perpendicular nor parallel to the propagation axis, we arrive at such beams that show us for the first time the observable evidence of the Beauregard effect. The advanced representation theory may yield any kinds of light beam, and the uncovered Beauregard effect would play its unique roles in applications.
Tunable Compact UHF RFID Metal Tag Based on CPW Open Stub Feed PIFA Antenna
Lingfei Mo,Chunfang Qin
International Journal of Antennas and Propagation , 2012, DOI: 10.1155/2012/167658
Abstract: For the ultrahigh frequency radio frequency identification (UHF RFID) metal tag, it always has the difficulties of compact designing, especially for the conjugate impedance matching, low antenna gain, and fabrication or environmental detuning. In this paper, a tunable compact UHF RFID metal tag is designed based on CPW open stub feed PIFA antenna. By changing the length of the open stub, the impedance of the PIFA antenna could be tuned in a large scale for conjugate impedance matching. The open stub makes it easy to tune the resonant frequency to alleviate the fabrication detuning or the environmental detuning, even after the manufacture. Moreover, the CPW structure of the open stub feed can resist the effects of the metallic surface and increase the antenna gain for the compact PIFA antenna. Modeling analysis and simulation are in good agreement with the measurement results. It showed that the UHF RFID metal tag could be designed compact with good performance based on the CPW open stub feed PIFA antenna.
Effects of Radix puerariae (Ge Gen) Water Extract on Exercise-Induced Fatigue in Mice
ZhongXin Xu,Chunfang Wang
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.1722.1726
Abstract: To investigate the effects of Radix Puerariae water Extract (RPE) on exercise-induced fatigue, 96 mice were randomly divided into four groups: Normal Control (NC), Low dose RPE Treated (LRT), Middle dose RPE Treated (MRT) and High dose RPE Treated (HRT) groups. The mice in the treated groups received RPE (2, 4 and 8 g kg-1, ig) and the mice in the normal control group received drinking water ig for 4 weeks. The exhaustive swimming time, Blood Lactic Acid (BLA), Blood Urea Nitrogen (BUN), Hemoglobin (Hb) and liver glycogen were determined after swimming test. The results indicated that RPE had significant anti-fatigue effects on mice. It extended the exhaustive swimming time of mice, increased the Hb and liver glycogen contents and decreased BLA and BUN contents.
