SINGH S.P.  MOHAMMADI Y.  MADAN S.K. 《浙江大学学报(A卷英文版)》2006,7(8):1329-1335

INTRODUCTION A number of experimental fatigue studies were conducted on plain concrete as well as on steel fibre reinforced concrete (SFRC) beams of different sizes under different loading conditions. Murdock and Kesler (1958) investigated the effect of stress ratio on the fatigue strength of plain concrete. Batson et al.(1972) reported fatigue strength of 74% and 83% of the first crack static flexural strength at 2 million cycles of complete reversed and not-reversed loads respectively…  相似文献   

The Homogeneity and Heterogeneity of Moral Functioning in Preschool     

Enda Tan  Amori Y. Mikami  Anastasiya Luzhanska  J. Kiley Hamlin 《Child development》2021,92(3):959-975

The current study examined relations between distinct aspects of moral functioning, and their cognitive and emotional correlates, in preschool age children. Participants were 171 typically developing 3- to 6-year-olds. Each child completed several tasks, including (a) moral tasks assessing both performance of various moral actions and evaluations of moral scenarios presented both verbally and nonverbally; and (b) non-moral tasks assessing general cognitive skill, executive functioning, theory-of-mind, and emotion recognition. Shyness and empathic concern were assessed from video acquired during participation. Results demonstrated positive associations among distinct moral actions, as well as among distinct moral evaluation tasks, but few associations between tasks assessing moral actions and moral evaluation. Empathic concern and inhibitory control each emerged as important predictors of preschoolers’ moral functioning.  相似文献   

Reliability and validity of the Learning Styles Questionnaire   总被引：1，自引：0，他引：1  

Y H Fung  Angela S P Ho  K P Kwan 《British journal of educational technology : journal of the Council for Educational Technology》1993,24(1):12-21

The reliability and predictive validity of a short form of Honey and Mumford's Learning Styles Questionnaire were examined. Students' learning preferences were measured by self-report ratings on their degree of likings for 19 teaching and learning activities commonly used in higher and professional education. Subjects were 381 second-year undergraduates enrolled in accountancy, engineering and communication programmes at the Hong Kong Polytechnic. The alpha coefficients for the four learning styles scales were quite low, ranging from 0.311 for the Pragmatist scale to 0.421 for the Reflector scale. Factor analysis of the items did not reveal any coherent factor structure congruent with the underlying constructs. However, significant though weak correlations were found between the learning styles scores and the learning preferences of the students as hypothesised.  相似文献   

Help-Seeking Stigma in Asian American College Women: the Role of Disordered Eating Cognitions and Psychological Inflexibility     

Akihiko Masuda  Bradly L. Goodnight  Stacey Y. Ng  L. Ward Schaefer  Erin C. Tully  Wing Yi Chan  Chad E. Drake 《International journal for the advancement of counseling》2017,39(2):188-201

Help-seeking stigma is considered a major obstacle to seeking professional psychological services in Asian American college women. Informed in part by objectification theory and the psychological flexibility model of behavior change, the present cross-sectional study examines the role of disordered eating cognition and psychological inflexibility in help-seeking stigma among a sample of Asian American college women (N = 257). More specifically, this study examined whether disordered eating cognitions and psychological inflexibility would mediate the association between psychological distress and stigma tolerance for seeking psychological services in this group. Results revealed that both greater disordered eating cognition and greater psychological inflexibility were associated with lower stigma tolerance, and each of them uniquely mediated the association between greater psychological distress and lower stigma tolerance. These findings suggest that disordered eating cognitions and avoidance-based coping and beliefs may contribute to help-seeking stigma and its association with psychological distress. Limitations of the study and the directions of future research are discussed.  相似文献   

Adoptive Parenting Cognitions: Acknowledgement of Differences as a Predictor of Adolescents’ Attachment to Parents     

Albert Y. H. Lo  Harold D. Grotevant 《Parenting, science and practice》2020,20(2):83-107

SYNOPSIS

Objective. Adoptive parents’ acknowledgment of differences is defined as the propensity to think that adoptive and nonadoptive families are different in important ways. Few studies have examined the implications of such cognitions for the parent–child bond. Design. Structural equation modeling was utilized to examine the relation between adoptive parents’ acknowledgment of differences and adolescents’ later attachment to their parents in a sample of within-race domestic infant adoptions. Data from 189 adoptive families were drawn from two waves (middle childhood, adolescence) of the Minnesota/Texas Adoption Research Project, a longitudinal study of openness in adoption. Results. Levels of acknowledgment of differences displayed by the adoptive mother and adoptive father during middle childhood positively predicted adopted adolescents’ feelings of attachment toward the respective parent 8 years later. This relation depended on adopted adolescents’ attitude toward adoption-related communication during middle childhood as well as the adoptive family’s level of openness during middle childhood. Conclusions. Acknowledgment of differences in adoptive families has positive implications for the parent–child bond.  相似文献   

Education Reform in Hong Kong: The “Through-Road” Model and its Societal Consequences     

Anita Y.K. Poon  Yiu-Chung Wong 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2008,6(3):33-55

Although Hong Kong’s education system has long been criticized as lacking in creativity and over-emphasising rote learning, on the whole it has served Hong Kong well in the past years, breeding outstanding business, academic and political leaders who continue to maintain Hong Kong’s competitive edge. The traditional elite schools have played a crucial role in the process. The education reform, which is still on-going, aims to overhaul the entire system by introducing the “through-road” model. To accomplish this, some mechanisms need to be changed. J.P. Farrell’s concepts of equality and equity, C.W. Mills’ concept of elitism, and P. Bourdieu and J. Coleman’s concepts of cultural and social capital will be applied to analyse the consequences of the reform. The paper argues that the education reform may be well-intentioned in eliminating some elements of inequality and inequity in education, but that this comes at the expense of Hong Kong’s cultural and social capital and leads to the development of new forms of inequality.  相似文献

Verbal aggression by parents and psychosocial problems of children   总被引：3，自引：0，他引：3  

Y M Vissing  M A Straus  R J Gelles  J W Harrop 《Child abuse & neglect》1991,15(3):223-238

Analyses of data on a nationally representative sample of 3,346 American parents with a child under 18 living at home found that 63% reported one or more instances of verbal aggression, such as swearing and insulting the child. Children who experienced frequent verbal aggression from parents (as measured by the Conflict Tactic Scales) exhibited higher rates of physical aggression, delinquency, and interpersonal problems than other children. This relationship is robust since it applies to preschool-, elementary school-, and high school-age children, to both boys and girls, and to children who were also physically punished as well as those who were not. Children who experienced both verbal aggression and severe physical violence exhibited the highest rates of aggression, delinquency, and interpersonal problems.  相似文献

Positive Illusion of exemplary altruists     

Jee Y. Lee  Hae Y. Chung 《Asia Pacific Education Review》2008,9(2):94-100

This paper examines the relationship between altruism and positive illusion, as formulated by Taylor and Brown (1988). It was predicted that, compared to the non-exemplary, general population, exemplary altruists would exhibit a higher level of positive illusion, which, in turn, suggests a higher level of mental health. Forty exemplary altruists and forty non-exemplary altruists were assessed in terms of positive illusion and compared with each other using Hotelling T²followed by univariatet-test. The results supported the prediction that exemplary altruists showed higher scores in terms of positive illusion than that of the non-exemplary general population. The implications of the results are discussed.  相似文献
