Abstract Students of the South have postulated that southern distinctiveness is eroding. Using General Social Survey data for 1972–1991, the convergence hypothesis is tested for regular church attendance. Regional convergence is found, but only for the rural South. Also, narrowing of regional differences in church attendance is especially pronounced among the young, indicating that the convergence is likely to continue. Despite these results, present church attendance levels remain significantly higher in the South than in the non South.  相似文献

An overview is given of methodology for testing goodness of fit of parametric models using nonparametric function estimation techniques. The ideas are illustrated in two settings: the classical one-sample goodness-of-fit scenario and testing the goodness of fit of a polynomial regression model.  相似文献

Studies have shown that conflict over parent–child relationships are frequently at the root of stepfamily dissolution and that the stepmother/daughter relationship is the most problematic stepfamily relationship. This paper explores the stepmother–daughter relationship in the family where the biological mother is an active parent and discusses the unique challenges and internal conflicts that the stepmother confronts on entry into the family and its web of preexisting relationships and transferences. “An internal parental stance” which underlies “good enough” stepmothering is conceptualized and the complex psychological processes which underlie this achievement are explored in this paper along with implications for clinical strategies. The term good enough stepmothering is a play on Winnicott’s concept of the good-enough mother—the maternal figure whose attunement to her child enables her to adapt appropriately to her child’s stage of life thus allowing an optimal environment for the child’s development.  相似文献

This study of 426 Canadian early adolescents (Mage = 12.52; 53% girls) investigated whether associations between popularity and indirect victimization (i.e., reputational victimization, exclusion) varied as a function of gender and the desire to conform to characteristics and competencies that are valued within the peer group (i.e., peer conformity goals). Regression analyses revealed popularity was uniquely and positively associated with reputational victimization, but was not significantly related to exclusion after accounting for the effects of meanness and likeability. The associations between popularity and indirect victimization were moderated by peer conformity goals and gender. The results indicated that popular girls with high peer conformity goals experienced more reputational victimization and exclusion than popular girls with low peer conformity goals. However, popular boys with high peer conformity goals experienced less exclusion than popular boys with low peer conformity goals. The findings suggest that peer conformity goals carry with them some risks for popular girls, but may serve a protective function for popular boys.  相似文献

Captain George Henry Lane‐Fox Pitt‐Rivers, Secretary General of the International Union for the Scientific Investigation of Population Problems (IUSIPP, 1928–ca. 1942), the precursor of today's International Union for the Scientific Study of Population (IUSSP, 1947–present), was a central figure in population science during the 1930s. With his pro‐Nazi activism, anti‐Semitism, Red‐baiting, and failure to leave any intellectual mark of consequence, he is an idiosyncratic and in some ways unattractive subject. However, an examination of Pitt‐Rivers's role as Secretary General reveals a wealth of information about the IUSIPP as it lurched toward collapse. It casts light, as well, on the struggle for scientific legitimacy between eugenic racialists and reformers in the 1930s, a struggle in which he played a controversial and divisive role. Using a combination of newly discovered and old archival material, this article traces Pitt‐Rivers's involvement with the Union, the British eugenics establishment, Nazi population science, and far‐right British politics during this turbulent decade when demography emerged as an international discipline.  相似文献

Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self-labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV-seropositive men who have sex with men. The majority of participants (88%) identified as a top, a bottom, or versatile. Tops were more likely to engage in insertive anal intercourse than bottoms, and bottoms were more likely to engage in receptive anal intercourse than tops, with versatiles reporting intermediate rates of both behaviors. Although the results suggest preliminary evidence regarding the predictive utility of self-labels, sexual behaviors of self-label groups were greatly overlapping. Differences were found among self-label groups in gay self-identification, internalized homophobia, sexual sensation seeking, and anxiety. Results suggest an added value in assessing self-labels in addition to asking about sexual behavior.  相似文献

One of the most challenging developments in recent historical studies and in empirical research in sociology has been constructionist theories relating to "sexual personalities." The "constructionist" view is that sexual identity is labile and can be therapeutically modified. In clinical work, this has presented an alternative view of the development of social sex-role and sexual orientation. Previously, views of sexual identity as a fixed personal characteristic (the "essentialist" view) provided clinicians with ways of treating psychologically distressed people either by transsexual conversion or aversion therapy. This article reviews some implications of "constructionist" and "essentialist" theory. It describes the author's clinical attempts to present constructionist views to clients who are in conflict about their sexual orientation and social sex-role. The article concludes that constructionist therapy has not taken into account clinical evidence that clients may adhere to "essentialist" beliefs.  相似文献

We propose a new and simple adaptive procedure for playing a game: ‘regret‐matching.’ In this procedure, players may depart from their current play with probabilities that are proportional to measures of regret for not having used other strategies in the past. It is shown that our adaptive procedure guarantees that, with probability one, the empirical distributions of play converge to the set of correlated equilibria of the game.  相似文献

This study examines the effects of marital and nonmarital union transition on health. Utilizing Canadian longitudinal data, we find that exiting both marriage and cohabitation seems to have similar effects: Dissolving either union tends to be associated with a decrease in physical health, mental health, or both. With possible selection effects eliminated and protection effects held constant, we find that remaining in either type of union generally is associated with poorer health. We speculate that decreased union quality may account for this inverse relationship, and that protection effects may explain much of the reported health gains associated with union life.  相似文献

A Gaussian conditional autoregressive (CAR) formulation is presented that permits the modelling of the spatial dependence and the dependence between multivariate random variables at irregularly spaced sites so capturing some of the modelling advantages of the geostatistical approach. The model benefits not only from the explicit availability of the full conditionals but also from the computational simplicity of the precision matrix determinant calculation using a closed form expression involving the eigenvalues of a precision matrix submatrix. The introduction of covariates into the model adds little computational complexity to the analysis and thus the method can be straightforwardly extended to regression models. The model, because of its computational simplicity, is well suited to application involving the fully Bayesian analysis of large data sets involving multivariate measurements with a spatial ordering. An extension to spatio-temporal data is also considered. Here, we demonstrate use of the model in the analysis of bivariate binary data where the observed data is modelled as the sign of the hidden CAR process. A case study involving over 450 irregularly spaced sites and the presence or absence of each of two species of rain forest trees at each site is presented; Markov chain Monte Carlo (MCMC) methods are implemented to obtain posterior distributions of all unknowns. The MCMC method works well with simulated data and the tree biodiversity data set.  相似文献
