Utilizing replies from a selected sample of contributors to the literature of symbolic interactionism, this paper examines the nature and extent of institutional ties among respondents holding similar views as to appropriate methodology in sociology. The specific institutional ties examined are those as: (1) fellow graduate students, (2) teachers and students, and (3) departmental colleagues. The methodological differences between the Chicago and Iowa schools, described in other studies, manifest themselves in the present sample, as do other views not neatly classifiable within either of these schools of symbolic interactionism. The more unconventional the conception of methodology held by a respondent, the more likely is the respondent to have been a fellow graduate student, a departmental colleague, and/or involved in a teacher-student relationship with other symbolic interactionists favoring the same conception. Respondents preferring the more orthodox methodological stances in modern sociology are less likely to have shared in such institutional ties. 相似文献

Causal models of initial occupational rewards for black and white males are developed from the responses of first-year workers in the National Longitudinal Surveys of Labor Market Experience. A comparison of the black and white models shows that while blacks have experienced considerable upward mobility, their income and prestige remain far behind their white counterparts. Two explanations for this racial gap are indicated by the data: (1) blacks begin work with lower levels of key background variables, and (2) racial discrimination in the labor market. Our measurement of racial discrimination in labor market entry accounts for only a small proportion of the gap between black and white levels of rewards; and when compared with earlier research, the data indicate a national trend of decreasing racial discrimination in the labor market. 相似文献

Data from the 1970 National Fertility Study are used to assess the extent and determinants of post-nuptial education among women in the United States. Over one-fifth of all women have attended high school or college since marriage; over one-third either have returned to school or anticipate returning to an academic institution sometime in the future. This phenomenon is apparently increasing since women married less than five years have already attended school in as great a proportion as women married 15-19 years. Examination of differentials reveals for both blacks and whites that post-nupital education is higher among women who: (1) attended college before marriage, (2) married early, (3) are currently separated or divorced, (4) support egalitarian sex-role attitudes, or (5) whose most recent occupation is in the professional, managerial, or administrative category. Post-nuptial trends in education undoubtedly reflect the much broader social phenomenon of changing sex-role perceptions. 相似文献

Two Ellsberg‐style thought experiments are described that reflect on the smooth ambiguity decision model developed by Klibanoff, Marinacci, and Mukerji (2005). The first experiment poses difficulties for the model's axiomatic foundations and, as a result, also for its interpretation, particularly for the claim that the model achieves a separation between ambiguity and the attitude toward ambiguity. Given the problematic nature of its foundations, the behavioral content of the model and how it differs from multiple priors, for example, are not clear. The second thought experiment casts some light on these questions. 相似文献

Two equivalent methods (gene counting and maximum likelihood) for estimating gene frequencies in a general genetic marker system based on observed phenotype data are derived. Under the maximum likelihood approach, an expression is given for the estimated covariance matrix from which estimated standard errors of the estimators can be found. In addition, consideration is given to the problem of estimating gene frequencies when there are available several independent population data sets. 相似文献

We consider a family of marked Poisson process models for the discovery of distinct errors in a computer program and also for sampling, in continu-ous time, a population containing an unknown number of distinct biological species. Captures (selections or discoveries) are assumed to occur at a con-stant rate, each event consisting of the discovery of a distinct process (error or species) or the recurrence of a previously discovered process. Using a generalization of Nayak’s (1988) model we derive confidence limits for the discovery rate. The limits are based on the asymptotic distribution of a scaled logarithmic function of the maximum likelihood estimator. 相似文献

ABSTRACTWe develop the concept of “social movement school’ (SMS), showing how these organizational spaces are deliberately designed for purposes of educating, mentoring, training, and coordinating individuals as effective, committed movement agents. SMSs can also be important sites of prefigurative design and practice for future societal development consistent with movement goals. We motivate the theoretical significance of SMSs based on five perspectives in social movement scholarship: (1) resource mobilization; (2) cultural approaches to repertoires of contention; (3) cognitive perspective; (4) micro-mobilization; and (5) biographical consequences of participation. We then offer a typology to capture primary purposes, and spatial reach within the broad field of SMSs. Within-movement variation is illustrated by focusing on a variety of SMSs in the U.S. civil rights movement; and the cross-movement breadth of the concept is illustrated by highlighting contemporary SMS forms drawn from three very different movements–labor, radical feminism, and mindfulness meditation movements. In the interest of launching a research agenda on SMSs, we end with several key questions that could serve to guide future research. Important theoretical, empirical, and practical considerations suggest that SMSs deserve the attention of scholars and activists alike. 相似文献
