Methods for estimating nonresponse bias are reviewed and severalmethods are tried on the 1980 GSS. The results indicate thatvarious estimating procedures are inappropriate and that eventhe more promising techniques can provide faulty estimates ofnonresponse bias. By its nature, nonresponse bias is very difficultto assess accurately and no simple, certain method exists.  相似文献

Using a sociodemographic model of the determinants of illegitimacy rates, a multivariate regression analysis of annual change in age-specific Swedish illegitimacy rates is applied to the 1911-74 period. The proxy measure of change in sexual activity was significant for all age groups. Legitimation rates for out-of-wedlock conceived births were significant for all ages except teenagers, and the final predictor, women's status, was significant for all ages except women 35-44. Explained variance for annual change was highest among ages 20-24 (66%), 25-29 (66%), and 30-34 (63%) and lower among teens (34%) and women 35-44 (47%). These results support earlier research that used a sociodemographic model to explain post-World War II change in cross-national illegitimacy rates among 23 developed countries.  相似文献

"The study compares determinants of internal and international migration intentions, drawing upon interview data from a sample of adults in Ilocos Norte, a largely rural province in the Philippines. A regression model is applied to test the relative determinants of intentions to migrate to Manila and to Hawaii. The study is based on a value-expectancy model of migration decision making. The results document the importance of subjective expectations related to the attainment of different values and goals in Manila and Hawaii."  相似文献

The purpose of this study was to examine gender differences in selected nonverbal behaviors associated with interruptions. Six graduate student groups involving 18 female and 17 male subjects were videotaped. The data for the study were 140 cross-sex interruption sequences and a matched, randomly selected sample of noninterruption sequences. A category system using self-related activity, gestures, body lean, facial expression and eye gaze was developed and used to code the data. There were no significant findings related to interruptions in the categories of self-related activity or gestures. Women leaned away from the group significantly more often than did men and when leaning away, women were more likely to be interrupted. Women were also more likely to be interrupted when smiling than were men, and women smiled significantly more when taking the speaking turn. Finally, women were interrupted significantly more often than men when they did not look at the turn-taker. The high educational status of the subjects was examined in the discussion of the findings.  相似文献

Working with a treatment and observing team at the same time, behind the oneway mirror, offers a variety of ways to: (a) generate multiple realities; (b) work with two different models of family therapy simultaneously; and (c) provide feedback on the teams' own roles, rules and group process. The process that 6 trainees and two supervisors used with T and O teams to examine their own coevolution as a therapeutic system using the Milan model of family therapy and Ericksonian hypnotherapy is described. The article concludes with a discussion of the advantages and pitfalls of this type of dual supervision.  相似文献
