Harter (1987) argues that both competence-importance discrepancy and social support/positive regard constructs predict a child's global self-worth. In the current study, this model was used to ascertain whether both determinants were pertinent to the self-worth of children with Developmental Coordination Disorder (DCD: American Psychiatric Association, 1994) and to control children. A group of 36 children with DCD were compared with a matched group of 36 normally coordinated children. The two groups were matched on variables of age, gender, and verbal IQ. It was found that Harter's (1987) model was supported for the group of control children as both the competence-importance discrepancy and the social support/positive regard construct were significant predictors of self-worth. However, for the DCD group, only the competence-importance discrepancy predicted self-worth. The results of this study indicate that future research efforts need to examine an alternative model which incorporates the variables that are relevant to the self-worth of children with DCD.  相似文献

Collaboration in large-scale projects introduces challenges involving both coordination (the ability to collaborate) as well as cooperation (the willingness to do so). Existing research has shown how modular designs can improve coordination by locating interdependencies within rather than between different modules. Based on an in-depth case study of collaboration in a large-scale infrastructure project, our study highlights an effect of modularity on collaboration that previously has been overlooked. Specifically, we show that while modular designs may help overcome coordination challenges by reducing interdependencies between modules, they can in turn hamper collaboration by emphasizing specialization within modules. Therefore, though existing work typically perceives modularity and integration as opposites, we clarify how they can also act as complements. In particular, we show how firms need to complement modular designs with integrating practices that stimulate cooperation. Overall, we contribute to the literature on collaboration and modularity by explaining when and how organizations can combine modularity and integration.  相似文献

ICTs and Internet adoption in China's tourism industry   总被引:1,自引:0,他引:1  
The fast development of information communication technologies (ICTs) and the expansion of the Internet have changed industry structures around the world. New technologies have been adopted in the tourism industry in Europe and America for more than 30 years, and the trend is likely to continue into the future. China, as a fast-growing developing country in Asia, is gaining importance in the international tourism market for its historical and cultural attractiveness as a destination. It is also becoming a booming tourism source country as its population starts travelling overseas. This study examines how the ICT and Internet gradually change the tourism industry structure in China; how important such changes are, and to where such changes will lead China's tourism industry. This exploratory research is conducted based on information collected from several tourism organisations, such as airlines, hotels, tour operators, visitor attractions and the tourism authorities within China.  相似文献

Studies with adults suggest that implicit preferences favoring White versus Black individuals can be reduced through exposure to positive Black exemplars. However, it remains unclear whether developmental differences exist in the capacity for these biases to be changed. This study included 369 children and examined whether their implicit racial bias would be reduced following exposure to positive Black exemplars. Results showed that children's implicit pro‐White bias was reduced following exposure to positive Black exemplars, but only for older children (Mage = ~10 years). Younger children's (Mage = ~7 years) implicit bias was not affected by this intervention. These results suggest developmental differences in the malleability of implicit racial biases and point to possible age differences in intervention effectiveness.  相似文献

Content analyses of prime-time television provide a picture of predominant cultural stereotypes and social trends. The present research is a quantitative content analysis of social class in popular broadcast and cable television in the United States. This research advances scholarship by systematically analyzing character class in addition to more commonly examined variables such as race and gender. A model for the operationalization of class for quantitative content analyses of mediated texts is offered. This proof of concept study demonstrates the viability of studying media representations of class quantitatively to systematically document patterns of portrayal.  相似文献

The developmental status and social–emotional functioning of young children who are homeless has received inadequate attention in spite of high rates of homelessness among families with young children and the potentially negative impact of homelessness and associated stressors on children’s well-being. The aim of this study was to gain understanding of homeless children’s social–emotional adjustment and their functioning in language, motor, and cognitive skills. We also examined gender and age differences in those areas of development. The sample included 328 children residing with their parents in one of 11 emergency shelter or transitional housing programs for families who were experiencing homelessness in a central North Carolina county. Child case managers administered the Brigance Early Childhood Screen II and the Ages and Stages Questionnaire: Socioemotional form in the shelter setting. Findings indicated variability in competence among the children, with some children performing above average on the developmental screening and demonstrating few social–emotional problems. However, developmental scores for overall functioning of the sample were significantly below the norming group, with particularly low functioning in language and communication skills. Parents of 24.8 % of the children had substantial concerns about their children’s mental health status. Although there are individual differences in adjustment of children experiencing homelessness, results support wide-scale screening and access to early intervention for these vulnerable children. Future investigations could be directed to identifying factors associated with resilience among children without homes.  相似文献

Sexual harassment is an interdisciplinary topic in organizational research that has received increased attention with the rise of the #MeToo movement. The online environment has complicated the experiences of employees who are sexually harassed by a coworker. One particular medium where online sexual harassment occurs is on social networking sites (SNS), such as Facebook. This research report examined how victims of sexual harassment believe organizations should handle online sexual harassment. We qualitatively coded 153 responses to the question, “What else do you think employers could do to handle sexual harassment on Facebook?” Our findings demonstrated a clear tension between whether harassment on Facebook is a private concern of the employee or a public concern of the employer/organization. Some victims advocating keeping work friends off of Facebook, while others suggesting having open door policies, conversations, and/or trainings. The difference in these approaches illuminates how the victims grappled with the public/private tension, and whether the organization should be made aware of their situations or if victims should handle it themselves. Implications of this research suggest that the blurred boundaries between employee face-to-face and online sexual harassment should continue to be explored, including why victims report harassment and to whom they report it.  相似文献

ABSTRACT

Online learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning.  相似文献
