黄河滩区移民搬迁的十个应注意事项

黄河滩区移民搬迁是河南省政府提高滩区居民生活水平和改善居民居住条件的一项重大民生工程。该项工程具有涉及人员众多、搬迁耗时长、动用的经费多等特点。黄河滩区移民搬迁应该根据实际,处理好诸如产业结构调整、搬迁安排、科学发展、民生建设和基础设施建设的关系、局部发展与全局发展的关系、是非关系等十大事项,以提高工作效率和减少政策执行中的失误。黄河滩区移民安置是一项系统工程,在具体设计政策时,必须基于防贫、防疫、防灾、防蝗、防火、防饥、防盗、防旱、防涝、防暴、防恐、防汛等多重需要,统筹兼顾,各部门协调配合。     

基于小波变换的二值模式检索

提出了一种基于小波变换后的二值模式图像检索.把图像库里的图像通过小渡变换压缩预处理,方便图像快速入库提取图像特征.选取二值模式技术处理,以便有效提取图像的特征进行检索.实验数据库采用Brodatz纹理图像库,对比了边缘拟合算法,共生矩阵和灰度纹理矩检索图像的检索效率,得出小波变换后的二值模式检索效率较高.     

博物馆参与式展览中的国家精神价值阐释——以新加坡游乐场(1930-2030)主题特展为例

新加坡国家博物馆的“当我们同在一起:新加坡的游乐场(1930-2030)”展览,以新加坡游乐场的发展历史为叙述主线,将知识宣教与参与式体验相结合,其立意并不限于游乐场自身的形式与设计之变迁,而将游乐场作为一种公共空间和社群交往的媒介,呼唤新加坡人重建社区认同,并以之助力于国民性之塑造。它也使我们得以思考,国家与社会倡导的核心价值观融入展览制作的策略性方式。

How do thinking styles and STEM attitudes have effects on computational thinking? A structural equation modeling analysis

Computational thinking (CT) is vital for success in numerous domains. However, the nature, definition, and scope of CT are ill-defined, and research on how best to develop CT is very limited. This study focused on how thinking styles and STEM attitudes have effects on computational thinking. Using a proportionate stratified random sampling procedure, 1195 students from two universities were surveyed. A structural equation modeling analysis showed that students' thinking styles and STEM attitudes directly predicted their computational thinking skills and that thinking styles mediated the relationship between STEM attitudes and computational thinking skills. Thinking styles and STEM attitudes are strong predictors of CT skills. Based on the results, we recommended that the conceptualization of CT be broadened to reflect its trans-disciplinary nature within the context of STEM education. This study adds to the limited theoretical understanding of CT and CT-predictors in higher education, which has been studied much less than in K-12 education.     

《海神家族》与《无字》中男性缺席的书写比较

陈玉慧的《海神家族》和张洁的《无字》,两部长篇小说皆通过对女性家族历史的记忆书写,将女性浮出历史地表,呈现出女性真实的生活场景和情感心理;两部作品虽然都书写了家族中男性形象的缺席。而在描写途径上有着明显的不同。对上述创作差异的比较,可以窥见海峡两岸女作家在家族历史书写中所凸显的女性生命悲剧、人格内涵及精神历程变迁。     

Design and Realization of InP/AlGaInAs Multiple Quantum Well Ring Laser

Using beam propagation method(BPM), key optical design parameters of InP/AlGaInAs multiple quantum well(MQW) ring laser were numerically analyzed. The influences of waveguide dimensions, curvature radius and gap size on the coupling efficiency were discussed. An InP/AlGaInAs MQW ring laser with radius of 350 μm was designed and realized. The experimental results show that the designed device, lasing at 1 563.2 nm with side mode suppression ratio higher than 20 dB, exhibited unidirectional bistability between the clockwise and counterclockwise modes.     

Physical Education Teacher Attitudes toward Fitness Tests Scale: Cross-Revalidation and Modification

This study aimed to provide further evidence of validity and reliability for the Physical Education Teacher Attitudes toward Fitness Tests Scale (PETAFTS), which consisted of affective and cognitive domains. There were two subdomains in the affective domain (i.e., enjoyment of implementing fitness tests and enjoyment of using test results) and one domain in the cognitive domain (i.e., beliefs in the usefulness of test results). Full-time physical education teachers (N?=?469) from two southwestern states in the United States participated in the study. Reliability and validity of the scale were examined. Alphas were computed for the entire 16-item scale, the affective and cognitive domains, and the two subdomains, respectively, to test the reliability. Confirmatory factor analysis (CFA) was employed to investigate the construct validity. The commonly used CFA indices, such as the chi square (χ²), the comparative fit index (CFI), the Tucker-Lewis Index (TLI), the goodness of fit index (GFI), and the root mean square error of approximation (RMSEA), were used to assess the fit of the data to the model. The CFA results suggested that the data from the study did not fit the original model proposed by Keating and Silverman (2004b) Keating, X. D. and Silverman, S. 2004b. Physical education teacher attitudes toward fitness test scale: Development and validation. Journal of Teaching in Physical Education, 23: 143–161. [Web of Science ®] , [Google Scholar], resulting in the elimination of item 3. The fitness of the data to the model was improved and deemed acceptable. More studies on the reliability and validity of the scale are needed in the future in order to use the scale with more confidence.
