论钢厂制造过程中能量流行为和能量流网络的构建

 本文对钢厂制造流程动态运行过程的物理本质进行了概要的描述,并在此基础上进一步指出：在钢厂制造流程中,铁素物质流与碳素能量流的关系是相伴而行的,而碳素能量流与铁素物质流的关系则是时合时分的。在钢厂制造流程中,不仅存在着铁素物质流网络及相关的运行程序,而且也存在着与铁素物质流转换有关的能量流网络及其运行程序。本文强调在研究钢厂的能源转换功能的方法时指出,不能停留在物料平衡、热平衡的方法上,而应该以动态的输入-输出概念和能量流网络的概念来进一步推动钢厂节能减排工作。本文还讨论了钢厂能量流运行的动力学机制以及能源管控中心的设计原则。进而从铁素物质流系统和碳素能量流系统提出了一系列钢厂节能减排的着手环节。特别对钢厂“只买煤、不买电、不用燃料油”的内涵与煤气等含能介质“近零”排放作了解释。提出中国钢厂的节能减排应该进入以建立能量流网络——能源管控中心为主要标志的新阶段。     

The voices of registered play therapists as supervisors.

This study examined the background, perceived training needs, and issues of Registered Play Therapist Supervisors (n = 305) and their supervisees. Supervisors completed a four-part survey regarding demographics, supervisor and supervisee issues, and perceptions of training needs for supervisors of play therapists. Important findings are the lack of training in and possible understanding of clinical supervision, the lack of perceived need for supervision of supervision, and the absence of countertransference as an important issue for supervisors.

Husbands' and Wives' Marital Adjustment, Verbal Aggression, and Physical Aggression as Longitudinal Predictors of Physical Aggression in Early Marriage.

Marital adjustment, verbal aggression, and physical aggression have long been associated in the marital literature, but the nature of their associations remains unclear. In this study, the authors examined these 3 constructs as risk factors for physical aggression during the first 2 years of marriage in 634 couples recruited as they applied for marriage licenses. Couples completed assessments at the time of marriage and at their 1st and 2nd anniversaries. Results of path analyses suggest that prior verbal aggression and physical aggression by both partners are important longitudinal predictors of physical aggression but do not support the role of marital adjustment as a unique predictor of subsequent physical aggression. Contrary to prior research, results also failed to support physical aggression as a unique predictor of marital adjustment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Physical status as a moderator of depressive symptoms among older adults with dual sensory loss.

Objective: This study evaluated the ability of three measures of physical status—physical activity, physical condition, and body mass index (BMI)—to moderate the relationship between dual sensory loss (DSL) and depressive symptoms in older adults. Method: Nationally representative longitudinal data were used to develop multilevel models predicting depressive symptoms among two groups of older adults, 1380 who developed DSL during the study and 1308 without sensory loss. Results: All three measures were associated with depressive symptoms for persons who had or would develop a DSL: participation in physical activity and being in better physical condition were associated with lower levels of depressive symptoms, while lower BMI levels were associated with higher levels of depressive symptoms. All moderator variables had a larger effect for persons with DSL as compared to persons without sensory loss. Implications: The implication of these findings is that participation in a regular program of physical activity may provide multiple benefits to older persons with DSL. Families and health care providers can offer support for being physically active by ensuring the person has the best possible correction for the sensory losses, providing encouragement, and/or providing physical assistance with exercise.

Childhood Sexual and Physical Abuse and the 1-Year Prevalence of Medical Problems in the National Comorbidity Survey.

In a population sample (N = 5,877; ages 15 to 54), the authors found childhood sexual and physical abuse to be associated with the 1-year prevalence of serious health problems for both men and women. The authors also found that participants' psychiatric disorders partially mediated the effects of physical and sexual abuse on adult health. However, childhood abuse continued to independently influence health status after the authors controlled for psychiatric disorders. Contrary to expectations, individuals who experienced a combination of sexual and physical abuse did not have a higher frequency of health problems than those who experienced either type of abuse alone. Implications for these findings are discussed, including possible mechanisms that may account for the association between childhood abuse and adult health problems.
