This article presents a historical account of the development of electronic devices along with an appreciation for the physics of semiconductors. Starting at the turn of the century with the work of J C Bose on Galena, the article leads us to recent low temperature experiments at IBM to demonstrate single electron transistors. 相似文献

Adolescents (n=43) previously diagnosed as dyslexic/reading disabled had markedly lower IQ scores on the newly standardized Wechsler Intelligence Scale for Children (WISC-III) than on the earlier administered WISC-R. The declines for Verbal, Performance, and Full Scale IQs were 10, 12, and 11 points, respectively, which were twice as great as in a subset of the standardization sample given both versions of the WISC. The adolescents did not show a significant decline in standard scores from the Wide Range Achievement Test (Level I to Level II). However, only two subjects had current reading and spelling standard scores above the 25th percentile. The impact of lower WISC-III IQs on guidelines for classification of students as learning disabled is discussed. 相似文献

OBJECTIVE: This study had two aims: First to examine psychosocial correlates of child maltreatment risk, and second to assess the validity of the CAP Inventory (Milner, 1986) with multiply disadvantaged teenage mothers. METHOD: Participants were 75 adolescent mothers who were wards of the Illinois child protection system. Mothers (aged 14-18) and infants participated in home-based psychosocial assessment of personal and parenting functioning. Group comparisons examined differences for mothers with elevated versus normal versus invalid CAP scores due to faking good. RESULTS: Findings indicated that abuse risk groups differed on emotional distress, social support satisfaction, reading achievement, and years of education, but not on parenting beliefs or quality of child stimulation. Differences favored the normal over the elevated risk group in all significant comparisons, whereas mothers with elevated faking good differed from normals only in lower reading achievement. Multiple regression analysis highlighted emotional distress, support dissatisfaction, and low achievement as significant predictors of greater abuse risk. CONCLUSIONS: Despite sharing multiple disadvantages, adolescent wards are a heterogeneous group who show different levels of psychosocial functioning corresponding to levels of child maltreatment risk. The findings provide support for the concurrent validity and clinical applicability of the CAP Inventory with disadvantaged teenage mothers. 相似文献

To assess the impact of a holistic career and life planning course on college students, the authors asked 209 students in treatment and control groups to complete measures of career development. Results indicate that the course significantly increases vocational identity and career decision‐making self‐efficacy and decreases career indecision. 相似文献

In this study, the reading comprehension of deaf children and adolescents in the Netherlands is examined along with their
word identification. The reading comprehension of 464 deaf students and the word identification of 504 deaf students between
6 and 20 years of age was examined. The results show the reading comprehension scores of deaf children to be far below the
scores of hearing children. On average, the deaf subjects scored at a level equivalent to a hearing child in the first grade.
The word identification scores of the deaf children, however, were almost equivalent to the scores of hearing children. Although
reading comprehension and word identification appear to be related, this relation does not completely explain the comprehension
difficulties encountered by deaf children. Additional factors are required to explain deaf children’s difficulties with reading
comprehension. 相似文献

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (Mage = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes. 相似文献
