The authors analyzed the reflective journals of 49 counselor trainees in internship using a conventional content analysis approach. Developmental insights from the 4 overarching themes and 7 subthemes are provided to assist counselor education and supervision programs in supporting the professional functioning of counselor trainees.  相似文献

This paper provides detailed evidence regarding the nature of selection into a school voucher system. We use micro-data on scholarship applications matched with state student-level records on test scores, schools attended, and demographic background characteristics to describe the attributes of students who choose to participate in Florida's Corporate Tax Credit Scholarship Program, a means-tested scholarship program that is the largest of its type in the United States. We find evidence that those who choose to participate in the program tend to be lower-performing students from poorly performing schools, and that students of different backgrounds tend to choose different types of private schools. Students participating in the program tend to select schools that have more white students and fewer minority students, regardless of student race.  相似文献

Zusammenfassung.   Die rasche Verbreitung und einfache Nutzungsm?glichkeit des World Wide Web (WWW) hat heute schon zu einer Vielzahl Web-basierter Datenbankanwendungen geführt. Man geht jedoch davon aus, da? das eigentliche Wachstum des WWW und seiner Anwendungen durch die Fortschritte in der Kommunikations- und Informationstechnik erst noch bevorsteht [10]. In diesem Beitrag stellen wir die bei der Realisierung Web-basierter DB-Anwendungen eingesetzten Techniken vor. Hierzu untersuchen wir zun?chst typische DB-Anwendungen, die über das WWW abgewickelt werden, um sie anhand ihrer Kriterien charakterisieren zu k?nnen. Daran anschlie?end diskutieren und analysieren wir nach einem überblick die unterschiedlichen Realisierungstechniken im Detail. Eingegangen am 22. Juli 1998 / Angenommen am 22. Oktober 1998  相似文献

Refugee children are at increased risk for mental health problems, including post-traumatic stress, depression, and externalizing problems. The refugee environment, maternal mental health, and parenting may reduce or exacerbate that risk. This study investigated their direct and indirect associations with child mental health cross-sectionally in a sample of Syrian refugee child–mother dyads in Lebanon in 2017–19. Mediating pathways were tested using structural equation modeling with 1446 dyads (child: Mage = 11.39, 52.1% females) and again 1 year later with 872 (child: Mage = 12.17, 53.1% females) of the original sample. Mediating pathways from the refugee environment through maternal mental health and parenting to child outcomes were detected, emphasizing the importance of a holistic approach to refugee mental health.  相似文献

Despite volumes written in the name of the new and fundamental feminist project in philosophy of science, and conclusions drawn on the strength of the hypothesis that the feminist project will boost progress toward cognitive aims associated with science and rationality (and, one might add, policy decisions enacted in the name of these aims), the whole rationale for the project remains (after 20 years, plus) wholly unsubstantiated. We must remain agnostic about its evidentiary merits or demerits. This is because we are without evidence to test the hypothesis: certainly, we have no data that would test the strength of the hypothesis as asserting a causal relationship between women and cognitive ends. Thus, any self-respecting epistemologist who places a premium on evidence-driven belief and justification ought not to accept the hypothesis. By extension, there is no reasoned basis to draw any definitive conclusion about the project itself. No matter how self-evidently correct.This article originated as a lecture for the Fifth International Conference of the German Society for Analytic Philosophy and is published by MENTIS in the GAP.5 Volume (2004).  相似文献

This paper reports the improvement of rectification effects in diffuser∕nozzle structures with viscoelastic fluids. Since rectification in a diffuser∕nozzle structure with Newtonian fluids is caused by inertial effects, micropumps based on this concept require a relatively high Reynolds numbers and high pumping frequencies. In applications with relatively low Reynolds numbers, anisotropic behavior can be achieved with viscoelastic effects. In our investigations, a solution of dilute polyethylene oxide was used as the viscoelastic fluid. A microfluidic device was fabricated in silicon using deep reactive ion etching. The microfluidic device consists of access ports for pressure measurement, and a series of ten diffuser∕nozzle structures. Measurements were carried out for diffuser∕nozzle structures with opening angles ranging from 15° to 60°. Flow visualization, pressure drop and diodicity of de-ionized water and the viscoelastic fluid were compared and discussed. The improvement of diodicity promises a simple pumping concept at low Reynolds numbers for lab-on-a-chip applications.  相似文献

Concurrent associations between teacher ratings of inattention, hyperactivity and pre-reading skills were examined in 64 pre-schoolers who had not commenced formal reading instruction and 136 school entrants who were in the first weeks of reading instruction. Both samples of children completed measures of pre-reading skills, namely phonological awareness, phonological memory, rapid naming, and letter name knowledge, as well as a measure of verbal ability. School entrants also completed measures of letter sound knowledge and beginning word identification skills. Teachers completed rating scales of inattention and hyperactivity. In the preschool sample, teacher-rated inattention and hyperactivity were not correlated with measures of children’s phonological processing but were correlated with letter name knowledge. In comparison, inattention, but not hyperactivity, was independently related to all measures of school entrants’ phonological processing and alphabet knowledge and their knowledge of high frequency words. Structural equation modelling on the school entrant sample revealed that the relationship between inattention and beginning word identification was mediated by pre-reading skills, suggesting that attention problems may compromise reading development during the earliest stages of learning to read through their impact on pre-reading skills. The findings are discussed in terms of their implications for the consideration of inattention in the design of effective and engaging early childhood learning environments.  相似文献

This paper examines the intercultural interaction experiences of local, first-year students (n?=?25) in their first few weeks at university. The focus on local students complements existing intercultural interaction literature, which has tended to concentrate on the experience of the ‘cultural other’ student. Employing qualitative analysis, the study revealed relationships between how students conceptualise culture, see diversity and experience their initial intercultural interactions on campus. A link between students' cultural backgrounds and the depth of their intercultural interaction experiences emerged.  相似文献

OBJECTIVE: Child sexual abuse (CSA) has been associated with adverse adult psychosocial outcomes, although some reports describe minimal long-term effects. The search for explanations for the heterogeneous outcomes in women with CSA has led to an examination of a range of CSA-related factors, from the severity of individual CSA incidents to the childhood family environment. This study compares three factors for predicting adult outcomes: a multidimensional CSA Severity Scale, the presence or absence of CSA, and family environment. METHODS: The effect of CSA on adult outcomes was examined among 290 community-dwelling women raised in intact families. Standardized measures and a focused interview were used to collect data, with siblings as collateral informants. RESULTS: Comparison of a multidimensional CSA Severity Scale to a dichotomous measure of the presence or absence of CSA showed that the Severity Scale did not have greater predictive value for adult outcomes than the dichotomous measure, nor was it as parsimonious. Childhood family environment scales added significantly to the predictive ability of the dichotomous measure. CONCLUSION: The specific characteristics of a CSA experience may be less important than the occurrence of CSA and the family environment of women for predicting long-term outcomes.  相似文献
