The study of childhood stress provides a useful perspective for assessing children's emotional status. Thematic projective techniques, like the Children's Apperception Test (CAT), may be useful in exploring children's perception of stress. For this purpose, a need-threat analysis is recommended to identify those underlying needs and threats that are likely to make a particular event or situation important, and hence potentially stressful, to an individual child. This paper introduces a scoring system for the CAT based on the analysis of thematic data in terms of five need-threat binaries, which serve as scoring categories. Preliminary data on reliability are presented. 相似文献

This article describes the author's personal/professional experience in designing the United States Holocaust Memorial Museum, a building that must “fit” in the context of the National Mall, express the spirit of the Holocaust, and become a permanent, living memorial. “The [building] did not pose the familiar problem of the container and the contained. This [must be] a building where the contained (the historical exhibition) works on the container (the architectural shell) and where the container has to join with the contained.” 相似文献

The roles and functions of 52 school psychologists from Iowa and Tennessee were examined. A multivariate analysis of variance (MANOVA) was used to test differences between reported time spent on prereferral, assessment, intervention, consultation, and curriculum-based assessment. Significant differences were found for the time spent in all areas. A second one-way MANOVA was used to test the differences between the two groups in reported actual time spent and desired time spent. A significant difference was found for consultation. A third MANOVA was utilized to test the differences between the two groups' desired time spent on the five variables. A significant difference was found for curriculum-based assessment. The results suggest that school psychologists in Tennessee and Iowa occupy different roles. School psychologists in Tennessee reported spending the majority of their time on assessment activities, whereas the Iowa sample balances their time between the five functions. The Iowa role exemplifies alternative functions for school psychologists. The Tennessee role is oriented more toward the refer, test, place model. 相似文献

This paper responds to a trend of contracting out subjective well-being econometrics to demonstrate social return on investment (SROI) for evidence-based policy-making. We discuss an evolving ecology of ‘external’ research taking place ‘between’ the academy and commercial consultancy. We then contextualise this as waves of research methodologies and consultancy for the cultural sector. The new model of ‘external between’ consultancy research for policy is not only placed between the University and the market, but also facilitates discourse between policy sectors, government, the media and the academy. Specifically, it enables seductive but selective arguments for advocacy that claim authority through academic affiliation, yet are not evaluated for robustness. To critically engage with an emergent form of what Stone calls ‘causal stories’, we replicate a publicly funded externally commissioned SROI model that argues for the value of cultural activities to well-being. We find that the author’s operationalisation of participation and well-being are crucial, yet their representation of the relationship problematic, and their estimates questionable. This case study ‘re-performs’ econometric modelling national-level survey data for the cultural sector to reveal practices that create norms of expertise for policy-making that are not rigorous. We conclude that fluid claims to authority allow experimental econometric models and measures to perform across the cultural economy as if ratified. This new model of advocacy research requires closer academic consideration given the changing research funding structures and recent attention to expertise and the contracting out of public services. 相似文献

This study aimed to establish between-day reliability and validity of commonly used field-based fitness tests in youth soccer players of varied age and playing standards, and to discriminate between players without (“unidentified”) or with (“identified”) a direct route to professional football through their existing club pathway. Three-hundred-and-seventy-three Scottish youth soccer players (U11–U17) from three different playing standards (amateur, development, performance) completed a battery of commonly used generic field-based fitness tests (grip dynamometry, standing broad jump, countermovement vertical jump, 505 (505COD) and T-Drill (T-Test) change of direction and 10/20 m sprint tests) on two separate occasions within 7–14?days. The majority of field-based fitness tests selected within this study proved to be reliable measures of physical performance (ICC?=?0.83–0.97; p?.01). However, COD tests showed weaker reliability in younger participants (ICC?=?0.57–0.79; p?.01). The field-based fitness testing battery significantly discriminated between the unidentified and identified players; χ2 (7)?=?101.646, p?.001, with 70.2% of players being correctly classified. We have shown field-based fitness tests to be reliable measures of physical performance in youth soccer players. However, results from the 505COD and T-Test change of direction tests may be more variable in younger players, potentially due to complex demands of these tests and the limited training age established by these players. While the testing battery selected in this study was able to discriminate between unidentified and identified players, findings were inconsistent when attempting to differentiate between individual playing standards within the “identified” player group (development vs. performance). 相似文献
