Based on many years of training students in both school and clinical psychology, the authors have formulated some impressions of differences and similarities found in these trainees. While generalizations remain tentative and call for research, the students in each of these disciplines seem to present different patterns in cognitive styles, perceptions of clients, conceptions of professional role, and personality characteristics. In personality, the students in these fields often display differences in need for structure, need for external support, social maturity, and desire for autonomous professional functioning. Differences seem to be related to variations in previous work and educational experiences, and to differences in age, sex and marital status. Implications for quality of service offered and training needs are outlined. 相似文献

ABSTRACT The aim of the present study was to investigate the existence of a relative age effect (RAE) on physical fitness of preschoolers. Anthropometry and physical fitness were assessed in 3147 children (3–5 years old) using the PREFIT battery. Based on the birth year, participants were divided into 3year groups (3-, 4- and 5-years). Within each year group, 4quarter groups were created: quarter 1, preschoolers born from January to March; quarter 2, from April to June; quarter 3, from July to September; quarter 4, from October to December. The MANCOVA analysis revealed a main effect of year group (Wilks’ λ = 0.383; F10,5996 = 369.64; p < 0.001, ηp 2 = 0.381) and of quarter (Wilks’ λ = 0.874; F15,8276.6 = 27.67; p < 0.001; ηp 2 = 0.044) over the whole battery of tests. To the best of our knowledge, this is the first study to report the existence of RAE at the preschool stage. In general, performance improved as the relative age increased (i.e., those born in quarter 1 performed better than those in the other quarters). Individualization strategies should be addressed within the same academic year not only in elementary or secondary years but also in preschoolers. 相似文献

ABSTRACT This essay reads the Latina/o/x migrant vernacular discourses that emerge out of pro-migrant activism. Anzaldúa’s notion of mestizaje – a logic of border consciousness – is put into conversation with Deleuze’s notion of nomad thought – a logic of movement – to inform a rhetorical strategy for reading the vernacular archive of social movement discourse. The “No Papers, No Fear” is one such social movement that demonstrate the logic of mestizaje/nomadism in their communication strategies. This study illuminates three tensions that define the ways Latina/o/x migrants in the US navigate the spaces of citizenship: tensions between movement/stasis, migrant identity/national identity, and fear/safety. 相似文献

ABSTRACTThis study aimed to assess the effect of playing surface (Natural [NT] and Artificial [AT] Turf) on the fatigue response to a soccer-specific exercise protocol (SSEP). Eighteen male soccer players completed the SSEP on NT and AT with pre-, post-, and 48 h post-assessments of eccentric knee flexor (eccKF) and concentric knee extensor peak torque (PT), peak countermovement (CMJ) and squat jump (SJ) height, and Nordic hamstring break angle. No significant main effects for surface or any surface and time interactions were observed for any of the outcome measures, except for eccKF PT recorded at 3.14 rad·s-1, which was significantly lower 48 h post-trial in the AT condition (AT = 146.3 ± 20.4 Nm; NT = 158.8 ± 24.7 Nm). Main effects for time were observed between pre- and post-trial measures for eccKF PT at all angular velocities, Nordic break angle, CMJ and SJ height. Nordic break angle, and both CMJ and SJ height were significantly impaired 48 h post-trial when compared to pre-trial. The findings of the current study suggest surface dependent changes in eccKF PT which may have implications for recovery and subsequent performance after competition on AT. 相似文献
