Child care studies that have examined links between teachers' qualifications and children's outcomes often ignore teachers' and children's transitions between classrooms at a center throughout the day and only take into account head teacher qualifications. The objective of this investigation was to examine these traditional assumptions and to compare inferences made from these traditional models to methods accounting for transitions between classrooms and multiple teachers in a classroom. The study examined the receptive language, letter-word identification, and passage comprehension skills of 307 children enrolled in 49 community-based childcare centers serving primarily low-income families in Colorado. Results suggest that nearly one-third of children and over 80% of teachers moved daily between classrooms. Findings also reveal that failure to account for daily transitions between classrooms can affect interpretations of the relationship between teacher qualifications and child outcomes, with the model accounting for movement providing significant improvements in model fit and inference.  相似文献

The Career Adapt-Abilities Scale—Brazilian Form (CAASBrazil) consists of four scales which measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. Internal consistency estimates for the subscale and total scores ranged from good to excellent. The factor structure was quite similar to the one computed for combined data from 13 countries. CAASBrazil is similar to the International Form, with the exception of two items that were not included in Brazilian version. Concurrent validity evidence was collected relative to personality factors from the Five-Factor Model of Personality. The relationships between career adaptability and personality factors were as predicted.  相似文献

In this paper we study some questions concerning ?ukasiewicz implication algebras. In particular, we show that every subquasivariety of ?ukasiewicz implication algebras is, in fact, a variety. We also derive some characterizations of congruence permutable algebras. The starting point for these results is a representation of finite ?ukasiewicz implication algebras as upwardly-closed subsets in direct products of MV-chains.  相似文献

The purpose of this work was to determine the epidemiological evolution of the Oppositional Defiant Disorder (ODD) in adolescents, using a sample of Secondary School students of the region of Campo de Gibraltar (Cadiz). The students' age ranged from 12 to 16 years old. Two evaluations were completed, the first one during the school year 2001-2002 and the second one in the school year 2006-2007. The sample comprised 2310 students in the first study and 2351 students in the second one. We used a comparative-selective approach. The results of the comparison revealed a prevalence ranging from 3.77% to 3.83% of students with this disorder, maintaining the main symptoms and with some changes in its distribution as a function of the school grade. Indeed, the data showed more cases in the final courses (1st study) in contrast with a higher concentration of cases in the initial courses (2nd study). With regard to the frequency of ODD by sex, we found that whereas in the earlier study (2001-2002), the relationship between boys and girls was 3.5:1, in the school year 2006/2007, the number of boys with ODD quadrupled the number of girls.  相似文献

This study investigates the impact of socioecological synchronization on the level and variations in children's attention at school. The aim was to re-examine previous results and broaden the chronopsychological scope of the research to include new synchronizers originating from proximal ecological niches. Two time-management factors were considered, the organization of the school timetable and the regular and predictable daily time with parents, influenced by work organization and compromises within the family. Two studies were conducted on a total of 498 children between six and 11 years of age. Results confirm a daily attention pattern. The level of performance and the daily pattern are affected by the two time-management factors whose beneficial or adverse influence depends on the child's age. Thus, while the weekly school timetable organized over four days has the strongest negative impact on attention performance for the two age groups, desynchronization due to a longer week-end is greater in the older children. The effects of the two possible four-and-a-half-day timetables also differ according to age. The benefits of working on Wednesdays for younger children appeared less beneficial for the older pupils. Regular and predictable daily time with parents does appear to play a role which also varies according to age, as it has an effect on younger children but has no impact on older children's attention or performance. This study confirms the synchronizing role of temporal messages from school and parental niches in the level and variations in children's attention at school, and is in line with the ecological point of view demonstrated by chronobiological studies. These findings support the importance of research that takes an overall approach to the child's environment. Further work should investigate the prioritization of social synchronizers according to their proximity to the child and how they interact.  相似文献

Background and objectives: Previous research indicated that more left-lateralized prefrontal activation during cognitive reappraisal efforts was linked to a greater capacity for generating reappraisals, which is a prerequisite for the effective implementation of cognitive reappraisal in everyday life. The present study examined whether the supposedly appropriate brain activation is relevant in terms of more distal outcomes, i.e., chronic stress perception.

Design and methods: Prefrontal EEG alpha asymmetry was recorded while female participants were generating reappraisals for stressful events and was correlated with their self-reported chronic stress levels in everyday life (n?=?80).

Results: Women showing less left-lateralized brain activity in the ventrolateral prefrontal cortex during cognitive reappraisal efforts reported experiencing more stress in their daily lives. This effect was independent of self-efficacy beliefs in managing negative emotions.

Conclusion: These findings underline the practical relevance of individual differences in appropriate brain activation during emotion regulation efforts and the assumedly related basic capacity for the generation of cognitive reappraisals to the feeling of being stressed. Implications include the selection of interventions for the improvement of coping with stress in women in whom the capability for appropriate brain activation during reappraisal efforts may be impaired, e.g., due to depression or old age.  相似文献

While the devastating effects of parental alcohol use on children’s health are well known, the specific impact of childbirth on parental alcohol consumption has rarely been examined in the general population. We sought to examine patterns of alcohol use associated with childbirth. Data were drawn from the US National Epidemiologic Survey on Alcohol and Related Conditions. We compared successively the characteristics of alcohol use among females living with a child under 1 year with (i) those of females not living with children under 1 year and (ii) those of females living with an older child. Mean daily ethanol intake was lower among females living with a child under 1 than among females either not living with children under 1 year (p?<?0.001) or living with an older child (p?<?0.01). Moreover, low-to-mild drinking frequencies fell among females living with a child under 1, compared with females either not living with children under 1 year (adjusted odds ratio (AOR)?=?0.56; 95% CI [0.40, 0.80] for at least once a month and AOR?=?0.40; 95% CI [0.27, 0.58] for less than once a month) or living with an older child (AOR?=?0.52; 95% CI [0.36, 0.75] for at least once a month and AOR?=?0.66, 95% CI [0.46, 0.94] for less than a month). No significant difference was found for males. Our study suggests that childbirth, as opposed to motherhood per se, reduces several (though not all) dimensions of alcohol consumption in females, but not in males.  相似文献
