Journal articles published by faculty in Commission on Accreditation for Marriage and Family Therapy Education (COAMFTE) programs from 1998 to 2002 were analyzed to determine patterns regarding the amount and type of research conducted by this group. Fifty-eight percent of the articles were identified as research. Slightly more than 10% of these dealt with clinical processes and outcomes. Forty percent of studies reported a specific source of funding. Twenty-nine percent of research articles used qualitative methods, with percentages rising over the course of time. Results suggest the average number of publications per faculty member was relatively low, particularly for senior faculty. Implications for these findings are discussed. 相似文献

The paper describes the application of the concept of working in multi-discipline groups in a company manufacturing air-handling fans and customised air-handling equipment on a jobbing type basis. The reasons for organising along these lines is explained together with the method used for formulation of groups. Operating experiences with this form of organisation are described and the results of an attitude survey of operatives and supervisors are discussed. 相似文献

Variability in PAH-DNA Adduct Measurements in Peripheral Mononuclear Cells: Implications for Quantitative Cancer Risk Assessment 总被引:2,自引:0,他引:2

Biomarkers such as DNA adducts have significant potential to improve quantitative risk assessment by characterizing individual differences in metabolism of genotoxins and DNA repair and accounting for some of the factors that could affect interindividual variation in cancer risk. Inherent uncertainty in laboratory measurements and within-person variability of DNA adduct levels over time are putatively unrelated to cancer risk and should be subtracted from observed variation to better estimate interindividual variability of response to carcinogen exposure. A total of 41 volunteers, both smokers and nonsmokers, were asked to provide a peripheral blood sample every 3 weeks for several months in order to specifically assess intraindividual variability of polycyclic aromatic hydrocarbon (PAH)-DNA adduct levels. The intraindividual variance in PAH-DNA adduct levels, together with measurement uncertainty (laboratory variability and unaccounted for differences in exposure), constituted roughly 30% of the overall variance. An estimated 70% of the total variance was contributed by interindividual variability and is probably representative of the true biologic variability of response to carcinogenic exposure in lymphocytes. The estimated interindividual variability in DNA damage after subtracting intraindividual variability and measurement uncertainty was 24-fold. Inter-individual variance was higher (52-fold) in persons who constitutively lack the Glutathione S-Transferase M1 (GSTM1) gene which is important in the detoxification pathway of PAH. Risk assessment models that do not consider the variability of susceptibility to DNA damage following carcinogen exposure may underestimate risks to the general population, especially for those people who are most vulnerable. 相似文献

In this article, maximum likelihood estimates of an exchangeable multinomial distribution using a parametric form to model the parameters as functions of covariates are derived. The non linearity of the exchangeable multinomial distribution and the parametric model make direct application of Newton Rahpson and Fisher's scoring algorithms computationally infeasible. Instead parameter estimates are obtained as solutions to an iterative weighted least-squares algorithm. A completely monotonic parametric form is proposed for defining the marginal probabilities that results in a valid probability model. 相似文献

This study offers a simultaneous equations model of the birth process with seven endogenous variables: four birth inputs (maternal smoking, maternal drinking, first trimester prenatal care, and maternal weight gain) and three birth outputs (gestational age, birth length, and birth weight). The data are taken from the National Longitudinal Survey of Youth. Our analysis conditions on twenty-nine exogenous variables including four racial dummies to account for the widely cited racial differences in birth outputs. We find that there is sizeable correlation between the disturbances in the four input and three output equations and among output disturbances, and that results from our simultaneous equations model are substantially different from those using the single-equation approach. It appears that the High/Low Risk Birth Weight Puzzle remains unresolved under our modeling framework.All correspondence to Kai Li.

One significant human rights violation in Southeast Asia is the exploitation of women through sex tourism. Such sexual exploitation occurs in Thailand because institutions are complacent and society accepts the practice. This case study, guided by the concepts of double binds and hegemonic masculinity, sought to understand if Thai culture is symbolically constructed in ways to portray Thailand as a desirable "sex tourist" destination. Websites portray Phuket as a patriarchal world where men can live their fantasies of being perfect hegemonic males because Thai bar girls are young nymphomaniacs that have no need to be talked to or understood. 相似文献
