Our research findings show that China's current IL standards of high schools contain a disproportionate emphasis on information technology(IT). Moreover, the stipulations of these IL standards are narrowly construed and without being solidly grounded on a broad and comprehensive educational perspective. We also suggest that there are two underlying causes for this set of unsound IL standards in China.Firstly, there is a lack of collaboration between two major competing forces engaged in the curricular development and research of IL in China: Those professionals in educational IT discipline vis-à-vis those in Library and Information Science. Secondly, library professionals have a very limited influence on major socio-cultural policies, even at their own institutions. As a result, this paper recommends the following three possible measures,which may help remedy this situation strategically: 1) Establishing a set of new IL curriculum standards based on an IL-centered educational perspective; 2) establishing a teacher-librarian's training program to promote school librarians' role in IL education; and 3) strengthening the research and development of an online IL education program and an accompanied evaluation mechanism.展开更多

Early response is necessary for infection control measures to avoid larger clusters. In Japan, (Nursery) School Absenteeism Surveillance System ((N)SASSy), which is a kind of school absenteeism surveillance, has activated since 2007 and covers about 60% of all schools and 40% of all nursery schools in 2017. Objective: The objective of the present paper is investigation and demonstration of how caregivers receive information related to infectious diseases in Japan and how (N)SASSy contributes health of children. Method: We randomly selected subjects with children by pre-fecture in October, 2017. The survey questionnaire asked background information and information about infectious diseases to maintain health in children. We regressed health concern variables on background information and information provision situation about community outbreaks using weighted logistic regression. Results: We received responses from 1172 people. Estimation results showed higher concern about a facility providing information about community outbreak. Caregivers whose children attend facilities provided about community outbreak or covered (N)SASSy significantly higher opportunity to arrange a schedule when a child has a high fever. Discussion: The obtained results demonstrated that activation in (N)SASSy affects the possibility of arranging a schedule when a child has a high fever. This capability might improve community health.展开更多

In order to explore the differences, influencing factors and ways to improve the information acquisition of college students in higher education institutions, 306 questionnaires from students in five higher vocational colleges were collected and analyzed. It was found that there was no significant difference in the information acquisition ability of students by gender. However, the majors of higher vocational college students have a significant impact on their information acquisition ability. It was suggested to taking comprehensive measures to improve the information acquisition ability of students in higher vocational colleges according to their characteristics.展开更多

And it has analyzed 2011-2013 investment and construction of the status quo in education funding for information technology equipment. The results show: Less Developed Areas in primary and secondary school education information and technology education equipment cannot meet the needs of the development of education with lack of funding support, poor school environment and information technology teaching conditions. And this phenomenon has been analyzed, and effective measures are to improve primary and secondary school education in underdeveloped areas of information technology conditions and educational level.展开更多

It has been proven to be accurate and effective registrationmeasure. Despite the general promising results, mutual information sometimes mightlead to misregistration because of neglecting spatial information and treating intensityvariations with undue sensitivity. In this paper, an extension of mutual informationframework was proposed in which higher-order spatial information regarding imagestructures was incorporated into the registration processing of PET and MR. Thesecond-order estimate of mutual information algorithm was applied to the registrationof seven patients. Evaluation from Vanderbilt University and our visual inspectionshowed that sub-voxel accuracy and robust results were achieved in all cases withsecond-order mutual information as the similarity measure and with Powell's multi-dimensional direction set method as optimization strategy.展开更多

It would seem therefore that extra dimensions would logically lead to a hyper-surface for a black hole and consequently a reduction of the corresponding information density due to the dilution effect of these additional dimensions. The present paper argues that the counterintuitive opposite of the above is what should be expected. This surprising result is a consequence of a well known theorem on measure concentration due to I.

With the analysis of homogeneity reliability, item analysis and factor analysis, this study constructs an assessment system to evaluate reliability and validity of the scale.Findings: The information-seeking behavior scale for undergraduates has divided undergraduates' information-seeking behavior into seven dimensions, which include 46 items. The reliability analysis of Cronbach's α was 0.910, and the coefficient of split-half reliability was0.817. The results of factor analysis showed that Kaiser-Meyer-Olkin(KMO) was 0.864,which indicates 55.536% of the total variation could be explained by the above seven dimensions.Research limitations: Due to a small sample size and limited sample distribution, further research need be conducted in an expanded sample size in order to explore the application scope of this evaluation system; in addition, the stability of the scale also need be confirmed.Practical implications: The paper sets up an information-seeking behavior evaluation system for undergraduates and explores the characteristics of their information-seeking behavior.This study provides guidance for the development of future information literacy education and the improvement of the information literacy level of undergraduates.Originality/value: An information-seeking behavior scale for undergraduates has been developed, which comprehensively covers information need, information source, information evaluation, information retrieval, information management, information utilization and information morality. The scale is proved to have good reliability, validity, popularity anddiscrimination that it is qualified to be an assessment tool of information-seeking behavior for Chinese undergraduates.展开更多
