The relation of attachment security to multiple domains of psychosocial functioning was examined in a community sample of 167 early adolescents. Security of attachment organization, assessed using the Adult Attachment Interview, was linked to success in establishing autonomy while maintaining a sense of relatedness both with fathers and with peers, even after accounting for predictions from qualities of the mother-teen relationship. Growth curve analyses revealed links of insecurity to increasing patterns of externalizing behavior and higher and stable patterns of depressive symptoms across adolescence. Implications for a developing theory of the connections of the attachment system to multiple domains of functioning in adolescence are discussed.  相似文献   

An Empirical Study of Geahigan's Inquiry Model in Learning Art at Senior Secondary School Level     

Cheung On Tam 《The International Journal of Art & Design Education》2019,38(2):344-359

The philosophical foundation for teaching art criticism in schools has been dominated by formalist and expressionist aesthetics, while from a practical point of view it has been influenced by art criticism models that emphasise observation and linguistic practices. Instead of asking students to observe an artwork and make verbal or written statements, George Geahigan proposed an inquiry‐based art criticism learning model that engages students in personal response, research, and aesthetic concept and perceptual skill acquisition activities. Using inquiry‐based art criticism as a foundation for curriculum development and connecting the model to authentic situations in schools, the present study investigated the effectiveness of the model on student learning. Fifteen secondary school teachers were invited to participate. Eight teachers taught the experimental group (n=85) with inquiry‐based curriculum plans and the other seven teachers taught the control group (n=82) with their own school curriculum plans. Students of both groups were asked to write an art criticism essay before and after the implementation of the curriculum plans. The results demonstrated that the overall improvement of the experimental group after one academic year was significantly greater than that of the control group. This article reports on the theoretical framework, methodology and results of the study. It was found that the inquiry‐based approach was a successful strategy in improving students’ skills in analysing, judging and using aesthetic and contextual knowledge in art criticism writing. The discussion focuses on the improvements that were made in the art criticism essays of the experimental group.  相似文献   

Harnessing collective intelligence of Web 2.0: group adoption and use of Internet-based collaboration technologies     

Xiao-Liang?ShenEmail author  Matthew K O?Lee  Christy M K?Cheung 《知识管理研究与实践》2012,10(4):301-311

Along with the advent of Web 2.0, mass collaboration is of paramount importance in knowledge exploration and diffusion. However, the extent to which Internet-based collaboration technologies can be used to develop new knowledge and to leverage the wisdom of crowds heavily depends on the collective willingness to adopt such tools together. In this study, the adoption and use of instant messaging has been conceptualized as a group-referent intentional social action. The concept of ‘we-intention’, which refers to one's perception of the group acting as a unit, is the focus of our interest. The cognitive, affective and social dimensions that contribute to ‘we-intention’ to adopt and use instant messaging were investigated. A survey was conducted and the findings provided empirical evidence supporting the idea that cognitive, affective and social factors jointly lead to the development of we-intention. This study is expected to provide some useful insights to both researchers and practitioners.  相似文献   

Student contribution in asynchronous online discussion: a review of the research and empirical exploration   总被引：1，自引：0，他引：1

The increasingly prevalent use of Internet in schools and homes has resulted in asynchronous online discussion becoming an increasingly common means to facilitate dialogue between instructors and students, as well as students and students beyond the boundaries of their physical classrooms. This article is organized into two main sections. In the first section, we review 50 empirical studies in order to identify the factors leading to limited student contribution. Limited student contribution is defined as students making few or no postings, or students exhibiting surface-level thinking or low-level knowledge construction in online discussions. We then identify the various empirically based guidelines to address the factors. In the second section, we discuss three potential guideline dilemmas that educators may encounter: (a) use of grades, (b) use of number of posting guideline, and (c) instructor-facilitation. These are guidelines where previous empirical research shows mixed results when they are implemented. Acknowledging the dilemmas is essential for educators and researchers to make informed decisions about the discussion guidelines they are considering implementing. Finally, we report two exploratory case studies on student-facilitation that we conducted. Using students as facilitators may be an alternative solution to educators who wish to avoid the instructor-facilitation guideline dilemma.  相似文献   

Complexity Reduction in Lattice-Based Information Retrieval     

Karen S. K. Cheung  Douglas Vogel 《Information Retrieval》2005,8(2):285-299

Though lattice-based information representation has the advantage of providing efficient visual interface over textual display, the complexity of a lattice may grow rapidly with the size of the database. In this paper we formally draw the analogy between Vector Space Model and Concept Lattice, from which we introduce the notion of Term-Document Lattice as a model for information retrieval. We then propose to use the idea of quotient lattice to reduce the complexity of a Term-Document Lattice. The equivalence relation required to construct the quotient lattice is obtained by performing a Singular Value Decomposition on the original term-document matrix.  相似文献

Understanding residents’ environmental knowledge in a metropolitan city of Hong Kong,China     

Lewis T.O. Cheung  Lincoln Fok  Eric P.K. Tsang  Wei Fang  H.Y. Tsang 《Environmental Education Research》2015,21(4):507-524

This study aimed to understand the environmental knowledge (EK) of the residents of Hong Kong. A territory-wide survey was administered to investigate the subjective and objective EK of the respondents as well as their means of receiving information about the environment. The results indicated that Hong Kong’s residents have a comparatively low level of EK, with a mean environmental knowledge score of 3.35 out of 8. The youngster (15–24?years old), students, and employed individuals reported more extensive EK than the older and unemployed respondents, thus suggesting that the younger generation and employed individuals have increased opportunities to receive EK through various channels. A weak positive correlation was identified between subjective and objective EK, thus implying that the residents of Hong Kong could not accurately evaluate their own level of EK. The results indicate that traditional media plays a significant role in disseminating EK. Digital media, such as websites and digital social networks, were also determined to be influencing factors in disseminating environmental messages to the younger generation.  相似文献

Effects of motion control footwear on running: a systematic review     

Cheung RT  Wong MY  Ng GY 《Journal of sports sciences》2011,29(12):1311-1319

Excessive foot pronation is a risk factor of running injuries and motion control footwear is designed to control foot pronation. With the movement transfer between foot pronation and tibial rotation, motion control footwear may not only be confined to controlling foot pronation. In view of the controversies in the literature on effectiveness of motion control footwear, this paper reviewed the efficacy of motion control footwear functions as reported in the literature. Eligible studies were identified from seven electronic databases. Two independent authors extracted the data and assessed the methodological qualities using the Jadad Scale. A total of 14 quasi randomised controlled trials were included. Even though the included studies were rated as "low quality" according to the Jadad Scale, the data were pooled and analysed. Results revealed that motion control footwear was effective in reducing the amount of foot pronation and the peak vertical impact during landing. There is no evidence that suggests motion control footwear for controlling kinematics of the proximal segments.  相似文献
