For people with refugee backgrounds, pursuing a meaningful career in their country of resettlement is important for their successful integration. However, for many, achieving this is a challenging process. Career counsellors may have a role to play in facilitating the transition and integration of people with refugee backgrounds, and narrative career counselling has much to offer. This article discusses the impact of prolonged transition under difficult circumstances on people with refugee backgrounds, and the potential contribution of narrative career counselling in assisting them. In particular, it identifies cultural considerations for narrative career counsellors who work with people with refugee backgrounds. 相似文献

Accumulating evidence indicates handwriting automaticity is related to the development of effective writing skills. The present study examined the levels of handwriting automaticity of Australian children at the end of kindergarten and the amount and type of writing instruction they experienced before entering first grade. The current study involved 177 kindergarten children enrolled in 23 classrooms from seven government-funded primary schools in Western Australia. Individual child level data (e.g., handwriting automaticity and word-reading skills) were collected and teachers were asked to complete a survey assessing the amount of time and types of writing activities developed in their classrooms (e.g., teaching basic skills and teaching writing processes). Hierarchical linear models were conducted to examine total variance attributable to child and classroom levels. Results showed a total variance of approximately 20% in children’s handwriting automaticity attributable to differences among classrooms when gender and word-reading skills were controlled for. Large variability was noted in the amount and type of writing instruction reported by a subset of participating teachers. Handwriting automaticity was associated with the teaching of revising strategies but not with the teaching of handwriting. Implications for writing development and writing instruction are discussed. 相似文献

The inhibitory effects of Lactobacillus plantarum-fermented and non-fermented Inula britannica extracts on the tyrosinase activity were comparatively investigated to examine whether and how they improve the whitening activity, and the contents of total flavonoids and polyphenolics as bioactive compounds were determined. The skin whitening activity using in vitro or ex vivo tyrosinase and L-3,4-dihydroxyphenylalanine (L-DOPA) staining was examined. The total flavonoid content (TFC) was increased by 13.4% after 72 h-fermentation. The viabilities of the B16F10 cells treated with the fermented and non-fermented control extracts were 100.26% and 92.15% at 500 μg/ml, respectively. In addition, the inhibition of tyrosinase activity was increased by the fermented samples from 29.33% to 41.74% following fermentation for up to 72 h. The tyrosinase activity of the untreated control group was increased to 145.69% in B16F10 cells. The results showed that I. britannica fermented by L. plantarum dose-dependently inhibited tyrosinase activity, which was stimulated by α-melanocyte stimulating hormone. These results suggest that lactic fermented I. britannica extracts can be used as effective skin-whitening materials. 相似文献

The PP intervals of pulse main peaks from healthy and unhealthy people(arrhythmia) have different nonlinear char-acteristics. In this paper,the extraction of PP intervals of pulse main peaks is achieved by picking up P peaks of pulse wave with wavelet transform. Furthermore,several nonlinear parameters(correlative dimensions,maximum Lyapunov exponents,com-plexity and approximate entropy) of the PP intervals of pulse main peaks extracted from normal and unhealthy pulse signals are calculated,with the results showing that these nonlinear parameters calculated from the main wave interval signals are helpful for analyzing human's health state and diagnosing heart diseases. 相似文献

This paper emphases on analyzing and investigating the mechanical behavior of electro-rheological fluid (ERF) semi-active damper. Theoretical model was developed to describe the relationship between electric field and the resistance force of ERF flowing through two parallel plane electrodes. In the model, the pressure drop along electrodes was supposed to consist of two parts: one related with viscosity and the other related with dynamic yield shear stress. The concept of yield stress influence factor was developed in 相似文献

This study compares the job satisfaction, job burnout and organizational cynicism of 233 early childhood teachers, 141 female and 92 male, with special attention to gender differences. Data were collected using a personal information form, Job Satisfaction Scale, Maslach Burnout Inventory-Educators Survey and Organizational Cynicism Scale, and the data were analyzed via independent-samples t-testing and one-way between-groups MANOVA. Significant differences between the male and female teachers were found across all three of the variables of interest, with the males having a higher level of organizational cynicism and lower mean job satisfaction. Also, males’ job burnout was higher than females’. However, the magnitude of these differences was medium only in the case of job satisfaction, with all other effect sizes being small. 相似文献

Even though several studies have reported positive attitudinal outcomes from context-based chemistry programs, methodological obstacles have prevented researchers from comparing satisfactorily the chemistry-learning outcomes between students who experience a context-based program with those who experience a content-driven program. In this narrative inquiry we are able to address the question: how do the recalled experiences of a student and her teacher in context-based and concept-based chemistry programs compare? From the student’s unique perspective of experiencing both programs with the same teacher, we have constructed our collective account around four themes; namely, the extent to which the student makes connections between chemistry concepts and real-world contexts, developing research independence through engaging in extended experimental investigations related to contexts, learning chemistry concepts through contexts, and conceptual sequencing in a context-based program. The student reported real-world connections between chemistry concepts and contexts, found her engagement in the context-driven tasks interesting and productive, and identified connected sequences of concepts across the contexts studied. Despite difficulties for teachers who are required to shift pedagogies, the student’s lived experiences and outcomes from a context-based program provide some encouragement in working through these issues. 相似文献
