Performance of Alcohol and Safer Sex Change Rulers Compared With Readiness to Change Questionnaires.

As part of a larger intervention study, the authors hypothesized that change rulers created for alcohol and safer sex would be equivalent to longer questionnaires. Ninety-six male college students completed rulers and questionnaires for assessing behavior change readiness. Participants' scores on the rulers significantly correlated with their scores on the questionnaires (r = .77 for alcohol; r = .77 for safer sex). In both domains, the rulers outperformed the questionnaires in predicting behavioral intentions, suggesting that the rulers had at least comparable concurrent criterion validity. This finding is the first of its kind in the safe sex literature and suggests that quick assessments of readiness to change are possible. Because the rulers are a continuous measure, the results are consistent with the idea that the change process is continuous rather than a series of discrete stages.

Assessing Positive and Negative Changes in the Aftermath of Adversity: Psychometric Evaluation of the Changes in Outlook Questionnaire.

The Changes in Outlook Questionnaire (CiOQ; S. Joseph, R. Williams, & W. Yule, 1993) is a 26-item self-report measure that was designed to assess positive and negative changes in the aftermath of adversity. This article had 3 aims: 1st, to investigate the factor structure of the CiOQ; 2nd, to test for internal consistency reliability and convergent and discriminant validity; and, 3rd, to investigate the association between positive and negative changes in outlook, posttraumatic stress, and psychological distress. Three studies are reported. Study 1 provides evidence that positive and negative changes are statistically separable and that the 2-factor model is a better fit than the 1-factor model. Studies 2 and 3 provide evidence for internal consistency reliability, convergent and discriminant validity of the CiOQ, and its associations with posttraumatic stress and psychological distress. In conclusion, the CiOQ has much promise for research on responses to stressful and traumatic events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Windows 2000环境下基于Miniport Driver实现软阵列的Buffer管理

Windows 2000操作系统下,通过Miniport Driver可以实现软阵列的功能。本文探讨了在这种软阵列中缓存的设计与实现,尤其是在缓存替换算法和通道并行性方面作了比较深入的研究。经在Takram公司的DC-200 EIDE扩展卡上进行测试,缓存的设计使小块I/O请求的性能得到明显改善。     

多线程通信方法在高频幅度控制中的应用

高频系统幅度控制环路开环时，束流将会在腔上引入与正常工作腔压可比的场，流强升高时束流要从腔上得到更多功率，此时腔自身消耗的功率保持不变，这就要求高频幅度控制发挥作用，满足束流和腔功率的要求。作为高频系统监控程序的一个组成部分，本文采用了多线程串口通信的方法实现了对SSRF高频系统激励电平的控制。
