情感计算在网络远程教育系统中的应用：功能、研究现状及关键问题

情感能力是人类智能的重要标志,情感的缺失会影响网络远程教育的教学质量和学习者的学习效果。情感计算是和谐人机交互与人工智能领域中新的研究方向。在网络远程教育系统中应用情感计算理论与技术,可以进一步优化网络远程教育的功能,帮助教师监测远程学习者的情感变化,调整教学策略和方法,实时给予学习者情感反馈,使教学质量达到最佳。目前国内外情感计算在远程教育方面的应用研究还处于起步与探索阶段,所构建的远程教学系统对远程教学中师生情感生理特征与心理特征、多模情感信息融合机制及网络虚拟人机情感交互特性等考虑不足,系统原型在情感合成与表达、智能人机情感交互实现上存在着很大的难度。因此,构建与人类情感系统相吻合的、自然和谐的、人性化和智能化的网络远程教育系统,需要有效解决师生面部表情、语音情感特征信号的准确识别与提取,师生多模情感信息融合机制与和谐人机情感交互技术等关键问题。     

Impulsive control for passivity and exponential synchronization of coupled neural networks with multiple weights

This paper investigates the passivity and synchronization problems for two classes of multiple weighted coupled neural networks (MWCNNs) with or without time delays. Firstly, by utilizing an impulsive control strategy and some inequality techniques, several passivity criteria for MWCNNs with diverse dimensions of output and input are established. Then, based on the Lyapunov functional, some sufficient conditions to ensure the synchronization of MWCNNs via impulsive control are derived. In addition, combined with the comparison principle and the impulsive delay differential inequality, the global exponential synchronization of MWCNNs with time-varying delays is considered under impulsive control. Finally, two numerical examples illustrate the effectiveness of the obtained results.     

突破性创新团队智力资本评价体系的理论构建与实证检验

团队智力资本是智力资本研究的一个重要而又相对薄弱的分支,迄今为止关于创新团队(特别是突破性创新团队)智力资本测评的研究文献屈指可数。在文献回顾的基础上,本文界定了突破性创新团队智力资本的概念,基于前人相关研究成果和前期定性访谈结果确定了其量表的构成维度以及各维度的测量指标(题项),即完成了突破性创新团队智力资本量表的理论建构,进而对该量表的信度与效度(包括内部一致性、收敛效度、区别效度和律则效度)进行了实证检验,并最终开发出具有较高信度和效度的突破性创新团队智力资本量表。研究结果表明,突破性创新团队智力资本量表由3个维度(团队人力资本、团队关系资本和团队结构资本)和14个测量指标构成。     

科技情报与科技智库的融合发展探析

与科技智库一样,面向科技创新决策提供支持服务一直都是科技情报的核心功能属性。本文从科技情报与科技智库机构发展的一体化、成果产出的趋同化和研究方法的定量化等三个角度,对当前科技情报与科技智库正呈出现融合发展的态势进行了分析研究。文章认为,随着我国大力推动中国特色新型智库的建设,科技情报与科技智库的融合发展,既给我国传统科技情报机构提供了新的发展机遇,也将加快推动我国科技智库体系的建设完善。     

Pre-service teachers' implicit and explicit beliefs about English language learners: An implicit association test study

Pre-service teachers' attitudes and beliefs about English Learners (ELs) are especially critical as they enter their professions among an increasingly diverse student population. This study uses an Implicit Association Test to explore implicit and explicit beliefs and attitudes of pre-service teachers about ELs. Pre-service teachers from a Southeastern U.S. university hold generally positive implicit beliefs about ELs and express positive expectations for working with ELs and school support. Implicit association test measures have potential as tools for preparing pre-service teachers and evaluating the impact of interventions that seek to improve teachers’ readiness to serve this population.     

Chinese university EFL teachers’ beliefs and practices of classroom writing assessment

This study investigates the extent to which university teachers’ beliefs about classroom writing assessment are congruent with their self-perceived practices in English-as-a-foreign-language (EFL) contexts, and what factors contribute to belief-practice inconsistencies. Drawing on data from a survey of 136 Chinese university EFL writing teachers and ten teacher interviews, results showed a degree of belief-practice alignment regarding assessment for learning (AfL) practices that make learning explicit, but belief-practice discrepancies were more salient. AfL practices that empower students to take responsibility in writing assessment were perceived to be more important than assessment of learning practices; however, the reverse was found in teachers’ practice. Impacts of micro-level factors including assessment training, teaching experience, student attributes, meso-level school factors, and macro-level assessment culture are discussed, and implications are drawn.     

Healing after traumatic events: Aligning interventions with cultural background and religious and spiritual beliefs

Historically, disaster response efforts have focused primarily on basic physical survival and safety—addressing medical emergencies and ensuring adequate shelter and supplies of food and water. However, in addition to physical survival, relief efforts must also consider strategies to promote emotional healing and psychological well-being. In particular, those who intervene must consider the acceptability of intervention strategies, taking into account survivors' cultural background, religious customs, and spiritual beliefs. This article offers recommendations to better align school-based therapeutic interventions with children's religious and spiritual beliefs.     

Profiling the Beliefs of the Forgotten Teachers: An Analysis of Intern Teachers’ Frameworks for Urban Science Teaching

The need to equip science teachers with knowledge, skills, and habits of mind to face the challenges of teaching science through inquiry informed this study, which analyzed the secondary science intern teachers’ beliefs about inquiry before, during, and following a series of 2 consecutive science methods courses in an attempt to document the effect of such experiences on their ability and willingness to infuse science inquiry in their science curricula. Nine science credentialing interns participated in the study. Data was gathered from their written reflections and various assignments throughout the methods courses. Results suggested that their beliefs changed significantly after the science methods courses. The implications of the study to secondary science teacher educators and researchers were highlighted.     

Sex differences in self‐estimation of multiple intelligences among Portuguese adolescents

This study investigated the relationship among sex, attitude toward intelligence, and self‐estimation of multiple intelligences for self and parents among Portuguese adolescents in secondary schools. Two hundred and forty‐two adolescents estimated their own and their parents' IQ scores on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual, and naturalistic. They also answered six simple questions concerning intelligence and intelligence tests. There were various sex differences in self‐estimated IQ: males rated themselves higher on overall, mathematical, spatial, intrapersonal, spiritual, and naturalistic IQ compared with females. Multiple regressions indicated that verbal, logical, and intrapersonal intelligence were significant predictors for self and parents overall IQ estimations. Factor analysis of the 10, the 8, and the 7 self‐estimates scores did not confirm Gardner's classification of multiple intelligences. Males were more likely to believe in sex differences in intelligence than females. Results are discussed in terms of the growing literature in the self‐estimates of intelligence, as well as limitations of that approach.
