Why Are You Bringing Up Condoms Now? The Effect of Message Content on Framing Effects of Condom Use Messages.

According to prospect theory (A. Tversky & D. Kahneman, 1981), messages advocating a low-risk (i.e., easy, low-cost) behavior are most effective if they stress the benefits of adherence (gain framed), whereas messages advocating a risky behavior are most effective if they stress the costs of nonadherence (loss framed). Although condom use is viewed as a low-risk behavior, it may entail risky interpersonal negotiations. Study 1 (N = 167) compared ratings of condom use messages advocating relational behaviors (e.g., discussing condoms) or health behaviors (e.g., carrying condoms). As predicted, loss-framed relational messages and gain-framed health messages received higher evaluations. Study 2 (N = 225) offers a replication and evidence of issue involvement and gender as moderators. Results are discussed with reference to the design of condom use messages.

The Impact of Rape on Women's Sexual Health Risk Behaviors.

This study used cluster analysis to identify three patterns of sexual health risk behaviors in a sample of adult rape survivors (N=102). Women in the 1st cluster (high risk) reported substantial increases from pre- to postrape in their frequency of sexual activity, number of sexual partners, infrequency of condom use, and frequency of using alcohol and/or drugs during sex. The 2nd cluster (moderate risk) reported increases in frequency of sexual activity and number of partners but mitigated that risk with increased condom use. Survivors in the 3rd cluster (low risk) indicated that their sexual health behaviors had become much less risky postrape. An ecological model predicting cluster membership revealed that individual-level and contextual factors predict patterns of risk behaviors.

Maternal Regulation of Infant Reactivity From 2 to 6 Months.

Previous research has investigated the effect of maternal soothing behaviors on reducing infant reactivity but not the differential effects of specific maternal behaviors on infant stress responses. The present study investigated maternal regulation of 2- and 6-month-olds' responses to an inoculation and found a significant decline with age in both the intensity and duration of infants' crying. Maternal affection and touching decreased from 2 to 6 months, whereas maternal vocalizing and distraction behaviors increased. At both ages, the combination of maternal holding/rocking and vocalizing was associated with decreases in all levels of infant reactivity. Neither strategy alone, however, was found to be effective. Feeding/ pacifying behaviors were effective only when initial distress was at a low or moderate level, which suggests that the effectiveness of maternal regulatory behaviors may depend on the intensity of infants' crying.

基于先验知识与DBM采样的类不平衡用电数据分类方法

智能电网建设过程中现有客户标签体系不够完善,针对海量用户用电数据的分类管理中带有标签的样本数据量小以及类不平衡分布的问题,提出了一种基于先验知识与深度玻尔兹曼机(DBM)采样的不平衡用电数据分类方法。首先,提取负荷曲线的特征,建立采样原则,利用先验知识和DBM对负荷曲线进行采样。然后,将采样数据通过极限学习机(ELM)网络进行训练。最后以爱尔兰用户用电数据为数据源,通过与原始非采样、随机过采样、合成少数类过采样技术(SMOTE)的对比性实验分析结果表明,所提出的基于先验知识与DBM采样的不平衡用电数据分类方法能够更好地对类不平衡用电数据集进行分类,实现用户用电行为的分析,有效支撑用户侧错峰避峰工作。     

ZVF型调节阀中不同阀瓣型线对局部流阻的影响

调节阀中不同阀瓣型线构成的通道，其局部流阻是不一样的。通过应用ANSYS2软件对DN50mmZVF型调节阀几种阀瓣型线在不同开度下构成的通道结构模型进行计算，从而得出流阻系数与开度的关系，并通过比较得到最佳阀瓣型线。该方法有很好的工程应用价值。
