Studies regarding the effectiveness of homework assignments in cognitive‐behavioral treatments have demonstrated mixed results. This study investigated predictors of compliance with homework recommendations and the time‐varying relationship of recommendation completion with treatment response in a brief couples' intervention (= 108). More satisfied couples and couples with more motivation to change completed more recommendations, whereas couples with children completed fewer. The association between recommendation completion and treatment response varied with the passage of time, with the strongest effect observed 6 months after the intervention, but no discernible differences at 1 year postintervention. Couples that completed more recommendations experienced more rapid treatment gains, but even those couples doing substantially fewer recommendations ultimately realized equivalent treatment effects, although they progressed more slowly. Implications are discussed.  相似文献

Early research on multiracials documents the existence of a newly emergent population, those who identify with more than one race or what is commonly now known as multiracials. Contemporary research on multiracialism has a new focus on the stratification that multiracials experience and how multiracials may be influencing a new racial hierarchy. This paper discusses some of the primary issues of multiracialism and stratification including colorism, the racial hierarchy, social class, gender and sexual orientation, and multiracial as a celebrity‐like status. As the multiracial population grows, so must the field of multiracialism grows to include critical issues and questions regarding stratification.  相似文献

This article reports the results of an evaluation of the effectiveness of different types of information materials in communicating the risk from exposure to radon, a naturally occurring indoor air pollutant. The study involved a panel of 2300 homeowners who actually experienced risks from radon, and the information program used to explain these risks. The analysis considered information transfer and performance on specific tasks requiring information on the risk from radon to measure learning. The results suggest a systematic learning process, but indicate that the process can be influenced by how risk information is presented.  相似文献

This is an evaluative study on the delivery of devolved programs in health, agriculture and social welfare. It aimed to identify the major devolved programs/projects implemented by the LGU of Columbio, Sultan Kudarat; the responsiveness of the actual delivery of devolve services in terms of human resources, facilities and fund allocation; the status of devolve services implemented if it was effective and efficient; and the inadequacies encountered. The “expose facto” method of research was used. There were 49 implementers and 132 beneficiaries of the various devolved programs. There were 181 total respondents. A four-part questionnaire was constructed and the gathered data were supplemented by information extracted through interviews with Key Informants, Focus Group Discussions and document analysis. There were three departments implementing the devolved social services programs such as the Municipal Health Office with 6 devolved health programs; the Municipal Agriculturist Office with 6 devolved agricultural projects; and the Municipal Social Welfare and Development Office with 7 devolved social welfare programs. The respondents rated the implementation of devolve services in health, agriculture and social welfare programs between rank 5 to 9 for the aspects of human resources, facilities and fund allocations. The respondents assessed the implementation of devolved programs as Very Efficient and Most Responsive programs to the needs of the people specially the children, youths and women. The study also found some inadequacies observed during the implementation of devolved social services programs which were Agreed by the majority of the respondents. These findings implied that the implementation of various devolved social services for several years has made a significant difference in the lives of the people of the Municipality of Columbio, Sultan Kudarat, the Local Government of Columbio and program implementers with their commitment and solidarity to serve the people especially the marginalized is a manifestation of their unselfish dedication to uplift the socio-economic condition and well-being of the people. Hence, continuing projects should further be strengthened and supported to ensure the sustainability of the projects even if the support of different institutions has been terminated.  相似文献

The career decision state (CDS) was studied in relation to RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) profiles in Self-Directed Search results among college students (86 women, 27 men). Three CDS dimensions measured by the Career State Inventory (CSI; certainty, satisfaction, and clarity) were examined as predictors of RIASEC primary and secondary constructs. Significant, albeit modest, zero-order correlations (p < .05) emerged between clarity and 3 secondary constructs (i.e., consistency, commonness, and coherence). Results of regression analyses indicated that CSI dimensions predicted 1 secondary construct (i.e., commonness).  相似文献

This paper considers modelling of a non‐stationary bivariate integer‐valued autoregressive process of order 1 (BINAR(1)) where the cross‐dependence between the counting series is formed through the relationship of the current series with the previous‐lagged count series observations while the pair of innovations is independent and marginally Poisson. In addition, this paper proposes a generalised quasi‐likelihood (GQL) estimating equation based on the exact specification of the mean score and the auto‐covariance structure. The proposed approach is also compared with other popular techniques such as conditional maximum likelihood (CML), generalised least squares (GLS) and generalised method of moment (GMM) based on simulated data from the proposed BINAR(1). Moreover, the model is applied to weekly series of day and night road accidents arising in some regions of Mauritius and is compared with other existing BINAR(1) models.  相似文献

With increasing frequency, firms are locating their operations in disparate countries with distinct national cultures and languages. This study develops and empirically tests hypotheses relating an operation's process compliance performance to (1) the presence of a language difference between the location of the operation and that of headquarters and (2) the national culture of the location of the operation and that of headquarters. Employing an international sample of pharmaceutical manufacturing plants located primarily in Western nations, the analysis reveals that a language difference between the location of a plant and the firm's headquarters is consistently related to decreased process compliance at the plant level. Regarding national culture, only limited evidence of a direct relationship between national cultural dimensions (at either the plant or headquarters location) and process compliance exists. However, the analysis does suggest that cultural congruence between the location of the plant and that of headquarters can relate to improved compliance performance. Such a relationship depends on the specific national cultural dimension studied. While these results are obtained in a specific manufacturing setting, they potentially have implications for process compliance in any global operation.  相似文献
