The present study explored how relationships with natural mentors may contribute to African American adolescents’ long‐term educational attainment by influencing adolescents’ racial identity and academic beliefs. This study included 541 academically at‐risk African American adolescents transitioning into adulthood. The mean age of participants at Time 1 was 17.8 (SD = .64) and slightly over half (54%) of study participants were female. Results of the current study indicated that relationships with natural mentors promoted more positive long‐term educational attainment among participants through increased private regard (a dimension of racial identity) and stronger beliefs in the importance of doing well in school for future success. Implications of these findings and directions for future research are discussed. 相似文献

This paper considers the copper electrodeposit ion processes in microvias and investigates whether the quality of the electroplating process can be improved by acoustic streaming using megasonic transducers placed into a plating cell. The theoretical results show that acoustic streaming does not take place within the micro-via (either through or blind-via' s), however it does help improve cupric ion transport in the area close to the mouth of a via. This replenishment of cupric ions at the mouth of micro-via leads to better quality filling of the micro-via through diffusion compared to basic conditions. Experiments showing the improved quality of the filling of vias are also presented. 相似文献

The purpose of this study was to identify the root metaphors of secondary classroom teachers and to observe ways in which these constructs influence teachers’ work with their students and their environments. Specifically, five case studies of novice teachers were presented. Results indicated that the metaphor of life as a tree was the most common view and that all five participants held a similar childhood metaphor in which they tended to idealize childhood. Overall, the data showed the persistence of ideas that beginning teachers bring to their university preparation and those beliefs extend into actual classroom practice. Teacher development seemed to be more influenced by the schooling environment rather than the pre‐service preparation the teachers received. Furthermore, these novice teachers felt conflict between their held beliefs and the reality of teaching and schooling. Implications for teacher educators and future research are included. 相似文献

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the
normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic
children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a
“surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition.
The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a
battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal
readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results
revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children
remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness
and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic
naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics.
A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception
word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over
one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit
Hypothesis. 相似文献

Architects create environments for human behaviour. Therefore they need — in addition to technical and design knowledge — some sort of “psychological” knowledge of the effects of their planning decisions on the occupant. The structure of this knowledge, which is only touched upon during architectural training, is the subject of an empirical study. Experts (experienced architects) and novices (students of architecture in their first or second year) were asked to judge the quality of the floor-plan layout of a four-room flat under three different conditions. From the expert-novice comparison, it is possible to gain insight into how professional experience shapes the knowledge of occupant needs and occupant behaviour. The results show remarkably few differences between the two groups. One possible reason lies in the special structure of architectural practice, which, due to a lack of feedback, makes it difficult to accumulate knowledge by evaluating experience. 相似文献

Cultural variation in relations and moment‐to‐moment contingencies of infant–mother person‐oriented and object‐oriented interactions were compared in 118 Japanese, Japanese American immigrant, and European American dyads with 5.5‐month‐olds. Infant and mother person‐oriented behaviors were related in all cultural groups, but infant and mother object‐oriented behaviors were related only among European Americans. Infant and mother behaviors within each modality were mutually contingent in all groups. Culture moderated lead–lag relations: Japanese infants were more likely than their mothers to respond in object‐oriented interactions; European American mothers were more likely than their infants to respond in person‐oriented interactions. Japanese American dyads behaved like European American dyads. Interactions, infant effects, and parent socialization findings are set in cultural and accultural models of infant–mother transactions. 相似文献

It is often claimed, both in the literature and by public opinion, that the status of teachers has declined sharply compared with the situation in the past. This article takes a more detailed look at the complex phenomenon of the ‘status’ of teachers. It does so on the basis of seven variables which ‘operatiohalise’ the process of social approval: the level of feminisation of the teaching corps, its social background, education, legal position and salary, the degree to which control has been obtained over the profession and its degree of social integration. Although a certain loss of prestige has undeniably occurred in comparison with other professions, it is evident that the status issue is not as clear cut as sometimes implied. In the first place, several contradictory trends were detected amongst the factors studied, indicating that the process of status acquisition and/or loss has not developed in a uniform manner. Moreover, statements concerning the relative status of this particular professional group always have to be related to other professions, regarding which the necessary basic data is not always present. It is evident, nonetheless, that the old (and not always very realistic) image of the ‘schoolmaster’ or ‘mistress’ with a ‘noble vocation’ to fulfil has faded nowadays, without the new ideal of the ‘education specialist’ yet establishing itself in the social context. 相似文献
