We conducted qualitative and quantitative reviews of the medical literature to develop an understanding of the linkages between nonspecific lower back pain (LBP) and employee absenteeism, and the efficacy of lower back pain interventions (LBPI) in reducing absenteeism. First, we offered a general time-based framework to clarify the causal flows between LBP and absence. Second, we inspected LBPIs designed to ameliorate LBP, which should, in turn, lead to reduced absence-taking. Third, we conducted a meta-analysis of 45 effect sizes involving 12,214 people, to examine the relationships between both LBP and LBPIs and absenteeism. Consistent with a presumption in the medical literature, we found support for the idea that chronic LBP has a positive overall relationship with absence-taking. The relationship was stronger for absence frequency measures than time lost measures. In addition, we found that increasing aggregation time (i.e., increases in the periods over which absence is observed) enhances the size of the chronic LBP-absence connection. Further, evidence showed that LBPIs were effective overall in reducing absenteeism. Finally, when there was a temporal mismatch between the form of LBP (acute vs. chronic) and the absenteeism aggregation period in LBPI studies, effect sizes were significantly smaller. We concluded with a discussion of these results, methodological limitations, and suggestions for future research that blends medical with organizational approaches to the etiology of absence. 相似文献

Intergenerational communication research has overemphasized dissatisfying experiences and treated elderly conversation partners as an undifferentiated category. To redress these limitations, the authors surveyed 100 younger adults' (16–46 years) satisfying and dissatisfying experiences with both family and nonfamily elders, and compared these with own-age peers. Measures of social contact were also taken. As hypothesized, positivity of experiences and contact increased from nonfamily to family elders and to peers. Barriers of communication with nonfamily elders were due to contact more than experiences. For family elders and especially for peers, most measures of contact and experiences were positive. The authors also tested for effects due to respondents' gender and culture (New Zealanders of Chinese or European descent). Females had more positive experiences and contact on some of the measures. Views about elders held by Chinese were more favorable, yet this did not translate into improved experiences or contact. 相似文献

The following investigations juxtapose jurisprudence and communication literatures to examine under what conditions racist speech is perceived as harmful. Specifically, one theory of legal liability, the tort of intentional infliction of emotional distress, and one intergroup approach, social identity theory, guided three empirical studies investigating verbally disturbing communication targeted at Asian Americans. The studies examined how the attribution of harm was influenced by variables such as group membership, message severity, message explicitness and the medium ofpresentation. One finding in particular, an interaction between group membership and message explicitness (direct vs. indirect), emerged across the three studies. Results revealed that as “objective” evaluators of deprecating speech, out-group members attributed the direct messages of racism to be more harmful than in-group members did, but, conversely, in-group members evaluated the indirect messages of racism to be more harmful than the out-group members did. Theoretical explanations for this finding and its resulting legal implications are discussed. 相似文献

An idiographic repertory grid method of measuring self-concept was used in a nomothetic design to study the relation between smoking behavior and four components of self-concept: real self, ideal self, social self, and ideal social self. Personal constructs were elicited from 32 smoker and 32 nonsmoker male and female college students. Differences between smokers and nonsmokers on all four components of self-concept supported the criterion-related validity of the measures. Implications were discussed for the assessment method and clinical practice. 相似文献

MOTIVATION TO LEARN AND COURSE OUTCOMES: THE IMPACT OF DELIVERY MODE, LEARNING GOAL ORIENTATION, AND PERCEIVED BARRIERS AND ENABLERS 总被引:4,自引:0,他引:4
This naturally occurring quasi-experiment examined how learning goal orientation (LGO), delivery mode (classroom vs. blended learning), and the perception of barriers and enablers related to motivation to learn and course outcomes. Study participants were 600 students enrolled in either classroom or blended learning courses. As hypothesized, learners in the blended learning condition, high in LGO, and who perceived environmental features as enablers rather than barriers had significantly higher motivation to learn. Motivation to learn, in turn, was significantly related to course outcomes (satisfaction, metacognition, and grades). The mediation hypotheses received partial support. Finally, exploratory analyses revealed 3 significant interactions between delivery mode, LGO, and perceived barriers and enablers on motivation to learn and course satisfaction. 相似文献

Progress in the study of relationships has depended in part on the recognition that relationships have properties not relevant to interactions or to the behavior of individuals, and may require additional principles of explanation. This has led to an emphasis on relationships as linking individuals. In this article we argue that relationship processes occur in the heads of individuals, with the participants having their own idiosyncratic views of the relationship as well as a shared one. The relationship is both affected by and affects the self‐concepts of the participants, so that the influences of the self‐concept may be critical for understanding the properties and dynamics of relationships Furthermore, consideration of the self‐concept can assist in the integration of different but not necessarily incompatible explanations for the same relationship phenomena. 相似文献

I will argue the free market in babies or in women's bodies created by an institution of paid surrogate motherhood is contrary to Kantian principles of person-hood and to the feminist principle that men do not have—and cannot gain through contract, marriage, or payment of money—a right to the sexual or reproductive use of women's bodies. 相似文献
