气质是个体出生之后就具有的一种明显而稳定的人格特征,对儿童未来的社会化、个性化发展具有重要影响。应用神经解剖、电生理、脑成像、神经生化与基因分析等技术,儿童气质的生物学基础研究日新月异。除了生物学因素外,非生物学因素,如早期生活经验对儿童气质发展的影响,也日益引起研究者的关注。养育者与教育者应理解并尊重不同气质类型的儿童,根据儿童不同的气质类型,为他们提供适宜的教育,把握儿童气质发展的关键期,整合基因、脑、个体经验及社会文化等因素,用关爱促进儿童气质的良性发展,同时重视艺术教育对儿童气质发展的调节作用。  相似文献   

Predicting crest settlement in concrete face rockfill dams using adaptive neuro-fuzzy inference system and gene expression programming intelligent methods     

Danial BEHNIA  Kaveh AHANGARI  Ali NOORZAD  Sayed Rahim MOEINOSSADAT 《浙江大学学报(A卷英文版)》2013,14(8):589-602

This paper deals with the estimation of crest settlement in a concrete face rockfill dam （CFRD）, utilizing intelligent methods. Following completion of dam construction, considerable movements of the crest and the body of the dam can develop during the first impoundment of the reservoir. Although there is vast experience worldwide in CFRD design and construction, few accurate experimental relationships are available to predict the settlement in CFRD. The goal is to advance the development of intelligent methods to estimate the subsidence of dams at the design stage. Due to dam zonifieation and uncertainties in material properties, these methods appear to be the appropriate choice. In this study, the crest settlement behavior of CFRDs is analyzed based on compiled data of 24 CFRDs constructed during recent years around the world, along with the utilization of gene ex- pression programming （GEP） and adaptive neuro-fuzzy inference system （ANFIS） methods. In addition, dam height （H）, shape factor （St）, and time （t, time after first operation） are also assessed, being considered major factors in predicting the settlement behavior. From the relationships proposed, the values ofR2 for both equations of GEP （with and without constant） were 0.9603 and 0.9734, and for the three approaches of ANFIS （grid partitioning （GP）, subtractive clustering method （SCM）, and fuzzy c-means clustering （FCM）） were 0.9693, 0.8657, and 0.8848, respectively. The obtained results indicate that the overall behavior evaluated by this approach is consistent with the measured data of other CFRDs.  相似文献   

Performance improvement of a crumb rubber modified bitumen using recycled glass powder     

Mojtaba Ghasemi  Seyed Morteza Marandi 《浙江大学学报(A卷英文版)》2013,14(11):805-814

In this study, the efficiency of bitumen and asphalt mixtures modified with crumb rubber （CR） and recycled glass powder （RGP） is evaluated. From an environmental point of view, the application of RGP in asphalt mixtures is considered beneficial since it prevents accumulation of waste glass in the natural environment. Rheological and mechanical properties of modified bitumen samples were investigated by laboratory methods such as bitumen conventional tests and dynamic shear rheometer （DSR）, and also by asphalt mixture performance tests including Marshall stability, indirect tensile strength （ITS）, compressive strength, and indirect tensile stiffness modulus. The results showed that the application of RGP in place of CR has no negative impact on the efficiency of bitumen and asphalt mixtures and even improves their engineering properties except for the toughness index （TI）. Moreover, a modification with 5% CR and 5% RGP in asphalt mixtures results in the best overall performance.  相似文献   

Library and information science literature: Research results     

S. Nazim Ali 《International Information and Library Review》2013,45(2):117-128

This paper reports the findings of a study on library fundraising in Pakistan. The review of literature revealed that no formal survey on this topic was carried out before. However, general library literature in the country mentioned the examples of donations and gifts received in libraries. An opinion survey of selected experts in the field of library and information science from various cities was conducted. Their interviews were also audio-recorded. The library leaders showed their opinions on the importance of various fundraising activities. A SWOT analysis (strengths, weaknesses, opportunities and threats) of Pakistani libraries was also conducted. The respondents also expressed their opinions about which institution/group should start the process of library fundraising. According to respondents “there is a potential for library fundraising” in Pakistani society. The paper stresses that Pakistani librarians should be made aware of the importance and methods of seeking private money to improve their services.  相似文献   

Measuring user satisfaction from e-Government services: Lessons from Jordan     

Ali Alawneh  Hasan Al-Refai  Khaldoun Batiha 《Government Information Quarterly》2013

User satisfaction is a crucial factor for continual usage of e-Government services and for the success or failure of e-Government projects. The main challenge for Jordanians is what are the key determinants of their satisfaction? This paper aims to identify the key factors that determine Jordanians' e-Satisfaction with Jordan's e-Government services portal. Based on an extensive review of relevant literature, five hypotheses are formulated and five factors are identified (i.e., security and privacy, trust, accessibility, awareness of public services, and quality of public services) that may affect the Jordanians' level of satisfaction towards using the Jordan e-Government portal (www.jordan.gov.jo). Survey data from 400 employees in four universities in the northern region of Jordan were collected and used to test the proposed hypotheses. Based on multiple linear regression and factor analyses, our empirical analysis demonstrates several key findings. These findings indicate the usefulness and importance to unveil the key drivers of e-Satisfaction so as to provide feedback in a set of recommendations that will enable creating e-Government portals which are compatible with citizens' needs, desires, and expectations. They also provide insights for both practitioners and governmental policy-makers to enhance e-Government portals via accounting diverse factors of technical, behavioral, managerial, and motivational aspects. Finally, implications and recommendations of these findings were discussed.  相似文献   

A cross‐cultural analysis of children's television use     

Ali Reza Zohoori 《广播与电子媒介杂志》2013,57(1):105-113

This study compared uses of U.S. television by foreign children residing in the U.S. and their American counterparts in light of theories of acculturation, cultivation, and uses and gratifications. Compared with U.S. children, foreign children: used television more for learning purposes, were relatively more interested in television programs, spent more time watching television, identified more frequently with television characters, and expressed stronger beliefs in the social reality portrayed by television.  相似文献   

Library Anxiety and Emotion Perception Among the Undergraduate Social Sciences Students: A Relationship Study     

Sajjad Ullah Jan  Mumtaz Ali Anwar  Nosheen Fatima Warraich 《Behavioral & Social Sciences Librarian》2013,32(2):52-63

ABSTRACT

Previous research has mostly focused on the demographic and academic correlates of library anxiety. This study focused on the “library anxiety” and “emotion perception” of students, with the objective of examining the relationship between these two concepts. In total, 279 self-reporting questionnaires were used for analysis. The results confirmed the existence of the phenomenon of library anxiety, with these students being more anxious regarding the “user education” and “user knowledge” factors. They showed greater skills of emotion perception. A negatively significant relationship appeared between library anxiety and emotion perception. The results suggest that user education and emotion perception training programs should be developed to overcome students' problems.  相似文献   

The mutual impact of personality traits on seating preference and educational achievement     

Camellia Hemyari  Kamiar Zomorodian  Iman Ahrari  Samar Tavana  Mohammad Parva  Keyvan Pakshir  Peyman Jafari  Ali Sahraian 《European Journal of Psychology of Education - EJPE》2013,28(3):863-877

Several studies have investigated the association between students' seating positions and their classroom performance. However, the role of personality traits on seating preference in the classroom has not been well investigated. The aim of the study was to understand how students choose their seats according to their personality traits in a classroom context and the influence of personality characteristics and seat selection on educational achievement. The seating positions of the medical students were recorded on an architectural plan during each class session, and the means and standard deviations of the students' locations were calculated in X and Y orientations. The locations of the students in the class were analyzed based on three architectural classifications: interactional zone, distance from the board, and access to the aisles. The NEO Five-Factor Inventory was used to evaluate the five main personality characteristics of the students. Midterm and final exam scores were used to measure the students' educational achievement. Analysis of variance showed a statistical significance correlation between the interactional zones and both agreeableness and conscientiousness. Mantel–Haenszel analysis showed a statistical significance association between sex and agreeableness and openness to experiences, which was mainly caused by zone II. Among the tested characteristics, a statistically significant relationship was observed between agreeableness and final exam scores. There was a statistical significance difference in openness and extraversion between the students with a high number of absences and their classmates. A relationship between the student's locations in the class, their educational achievements, and some of their personality characteristics are addressed.  相似文献   

Student perceptions of a culturally diverse classroom environment     

Sadaquat Ali  David Rohindra 《Research in Science & Technological Education》2013,31(2):149-164

The research in the paper involves an application of the actual and preferred versions of a previously‐validated learning environment instrument: the What is Happening in This Classroom (WIHIC) instrument in a complex multi‐cultural university‐level environment. Statistical analyses suggest the instrument is valid in this setting (with Cronbach alpha above 0.80 for all scales), and data analyses using ANOVA point to relatively few differences between preferred and actual environments. The research findings suggest all students would prefer a more interactive and equitable classroom, the latter issue of particular importance for one cohort, namely Indo‐Fijians (descendents of ethnic Indian indentured labourers). With the exception of this, there are few differences based on ethnicity and further analysis also suggests no differences in perceptions vis‐à‐vis collaborative versus competitive learning environments, excepting that analysis based on gender shows females have a slight preference for a more cooperative learning environment.  相似文献
