Two studies were conducted in all-electric townhouses and apartments in the winter (N = 83) and summer (N = 54) to ascertain how energy conservation strategies focusing on thermostat change and set-backs and other low-cost/no-cost approaches would affect overall electricity use and electricity used for heating and cooling, the home thermal environment, the perceived comfort of participants, and clothing that was worn. The studies assessed the effectiveness of videotape modeling programs that demonstrated these conservation strategies when used alone or combined with daily feedback on electricity use. In the winter, the results indicated that videotape modeling and/or feedback were effective relative to baseline and to a control group in reducing overall electricity use by about 15% and electricity used for heating by about 25%. Hygrothermographs, which accurately and continuously recorded temperature and humidity in the homes, indicated that participants were able to live with no reported loss in comfort and no change in attire at a mean temperature of about 62 degrees F when home and about 59 degrees F when asleep. The results were highly discrepant with prior laboratory studies indicating comfort at 75 degrees F with the insulation value of the clothing worn by participants in this study. In the summer, a combination of strategies designed to keep a home cool with minimal or no air conditioning, in conjunction with videotape modeling and/or daily feedback, resulted in overall electricity reductions of about 15% with reductions on electricity for cooling of about 34%, but with feedback, and feedback and modeling more effective than modeling alone. Despite these electricity savings, hygrothermograph recordings indicated minimal temperature change in the homes, with no change in perceived comfort or clothing worn. The results are discussed in terms of discrepancies with laboratory studies, optimal combinations of video-media and personal contact to promote behavior change, and energy policies that may be mislabeled as sacrificial and underestimate the effectiveness of conservation strategies such as those investigated in these studies. 相似文献

妊娠合并结核是一种对母婴健康危害极大的妊娠期疾病。在妊娠期结核病中,多数患者无明显症状,早期症状与妊娠期某些生理反应相似,加之妊娠与结核病的相互影响,x线、CT等重要的影像学检查受限,致使本病易被误诊或误治。某些抗结核药物对母婴的不良影响,使其治疗难以实施,由于结核病本身及治疗后可能对胎儿的影响,在临床上是否终止妊娠往往难以决策。本文就妊娠合并结核诊治过程中的相关问题进行综述,以期为临床诊治决策提供帮助。 相似文献

对建立我国艾滋病防治督导与评估体系的思考 总被引:1,自引:0,他引:1
随着我国艾滋病防治工作的持续深入,定期对艾滋病防治工作进行督导与评估越来越重要。但是,到目前为止,我国尚未建立国家综合协调的艾滋病防治督导与评估体系。通过对建立国家艾滋病防治督导评估体系的必要性、可行性及存在的问题进行分析,围绕如何构建一个统一、综合、有效的督导评估体系提出政策建议。 相似文献

We conceptually define and empirically investigate the accumulation of work experience—a concept that refers to the extent to which executives have amassed varied levels of roles and responsibilities (i.e., contributor, manager, lead strategist) in each of the key work activities that they have encountered over the course of their careers. In studying executives’ work experience accumulation, we consider key antecedents such as executives’ cognitive ability and personality traits, namely Extraversion and Openness to Experience, and examine the value of work experience accumulation on executives’ strategic thinking competency. Analyses of multisource data from 703 executives revealed 3 key findings: (a) accumulated work experience positively relates to executives’ strategic thinking competency after controlling for individual characteristics and other measures of work experience; (b) executives’ cognitive ability demonstrates the strongest and most positive relationship to executives’ strategic thinking competency; and (c) extraverted executives tend to achieve higher levels of work experience accumulation. Relative weight analyses also indicated that cognitive ability and accumulated work experience are the 2 most important predictors for executives’ strategic thinking competency among the other predictors. These findings are discussed in light of their practical implications. 相似文献

A combination of social marketing, communications, social learning (particularly modeling), and behavior analysis may provide an effective framework for behavior change via films and television. We used this approach in developing special television programs about residential energy conservation. The programs were tailored and directed to preselected middle-class homeowners (N = 150), and delivered over a public access channel of a cable TV system. The results indicated that after one program exposure (about 20 minutes), viewers adopted simple strategies modeled in the programs which led to savings of approximately 10% on their home energy use for a substantial part of the cooling and heating season. Although the potential benefits to costs of large-scale media efforts seemed great, institutional barriers for such programs were identified. Less expensive, more local programs seem more viable. 相似文献

A recently developed procedure produces substantial improvements in the accuracy of corrections for range restriction and reveals that predictive validities of employment selection methods are higher than previously thought. This study applied this procedure to meta‐analytic validities of 2 personality measures (Conscientiousness and Emotional Stability) and general cognitive ability measures. Results show that the increases in validity estimates are greater for cognitive ability than for personality, reducing the relative validity of personality. In addition, the incremental validity of these personality measures over that provided by cognitive ability is smaller than previously estimated. Path analyses based on the more accurate data reveal relatively smaller path coefficients from these personality traits to job and training performance. These findings have implications for theories of job performance and for the practical value in selection of personality measures relative to cognitive ability measures. 相似文献
