An effective measure of childhood adversity that is valid with older adults

Childhood adversity (CA) has life-long effects that we are just beginning to understand. The Midlife in the United States (MIDUS) data is a rich resource that could contribute to the knowledge of the impact of CA in the later years but, while a number of CA items are included in MIDUS, a cumulative CA scale based on those items has not been created. Development of a CA scale would create numerous research opportunities within MIDUS and overcome some of the challenges of using a secondary dataset. The present study aimed to demonstrate that a cumulative measure of CA that is valid with older adults could be created using retrospective MIDUS Refresher study data (Ryff et al., 2016); analysis included data collected from 2011 to 2014 from 2542 adults ages 23–76 (1017 adults 55–76). The present study provided a rationale for which measures of CA to include in a cumulative scale. The distribution of eight types of CA and the cumulative CA scale were consistent with findings from past studies of CA. The factor structure of the cumulative CA scale was similar to the original ACE study and included two factors: household dynamics and child abuse/neglect. Consistent with past studies, the CA scale predicted a negative association with life satisfaction and a positive association with number of chronic conditions. This study demonstrated that an effective cumulative measure of CA could be created that would be of value to other studies using MIDUS data to explore outcomes with older adults.

Assessing School Readiness: Validity and Bias in Preschool and Kindergarten Teachers' Ratings

As a part of efforts to evaluate and monitor the increasing public investment in early childhood education, teachers are being asked to assess children's school readiness. In this study, preschool teachers and kindergarten teachers rated children's skills in three areas (kindergarten readiness, academic skills, and communication skills), and these ratings were compared with direct assessments of the children's skills. Ratings by both groups of teachers tended to be more highly related to basic skills, such as counting and number naming, than to abilities such as solving applied problems and using expressive and receptive vocabulary. Preschool teachers' ratings had a lower association with children's observed skills and abilities than kindergarten teachers' ratings. Ratings of children attending Head Start were systematically inflated, but this relationship was mediated to a significant extent by the teachers' levels of education. More educated teachers rated children in a manner consistent with the children's directly assessed skills. Implications of these findings for informing future efforts to assess school readiness by using teacher ratings are discussed.     

举办大型运动会与城市生态环境保护的探讨

研究采用实地考察、文献分析以及生态学、城市规划、环境保护基本原理等。通过研究大型运动会城市生态环境问题的产生、特点和表现，提出举办大型运动会与城市生态环境保护协调措施。认为，大型运动会引起城市生态环境的问题主要表现在：(1)体育场馆设施建设；(2)建材的使用与废弃；(3)城市环境污染；(4)场馆设施与交通能源利用；(5)体育场馆设施赛后利用等。在举办大型运动会中，要确保城市生态环境的可持续发展，一是制定大型运动会城市生态环境保护具体规划，二是促进公众参与，加强城市环境治理。     

想象训练研究现状的分析

本文采用文献资料法对近十年刊载在中美四种主要期刊上的想象训练研究报告作了分析。结果表明想象训练正在从有效性研究向过程变量研究深化 ,研究面也由简单技术向复杂技术扩展 ,指出了目前复杂技术研究明显不足 ,还指出了基础理论在过程变量控制方面的研究严重滞后 ,在一定程度上影响了想象训练研究的进一步深化。本文为想象训练的研究和应用提供了有益的综合信息。

我国大学生体质评价体系相关指标有效性和可靠性研究

采用文献资料法、体质测试法、数理统计法、逻辑分析法对当前我国19～22岁大学生体质评价体系指标进行有效性和可靠性研究。结果显示：我国大学生体质评价体系指标应增加“皮脂指标”和“台阶试验”；我国大学生体质评价体系指标中刺激强度较大的耐力性指标和容易受精神因素和激励因素影响的指标的可靠性较差。
