A projective (2n,n,λ,1)-design is a set of n element subsets (called blocks) of a 2n-element set V having the properties that each element of V is a member of λ blocks and every two blocks have a non-empty intersection. This paper establishes existence and non-existence results for various projective (2n,n,λ,1)-designs and their subdesigns. 相似文献

This paper examines the theoretical and empirical basis for common rank-orderings of occupational roles by raters throughout the world. From an illustrative comparison of occupational stratification in Australia and the United States we conclude tentatively that (1) commonalities in the socioeconomic characteristics of occupational roles provide the basis for interplace consistencies in “prestige” scores, (2) the structure of occupational mobility in the U.S. and Australia is largely similar, (3) this similar structure of occupational stratification manifests a common socioeconomic process which defines a (the?) major component of occupational mobility in capitalist, industrial (only?) societies. We infer that “prestige” scores for occupations are fallible estimates of the socioeconomic statuses of occupation, within the context of mobility processes in (at least) the U.S. and Australia. 相似文献

Psychological data was obtained from 1009 couples located in 5 countries who were practicing the temperature-rhythm method of birth control. In the U.S., survey instruments were distributed to 160 couples by mail with a 58% (92) return rate of completed questionnaires. The educational attainment of both men and women exceeded senior high school. Most wives were not gainfully employed, and 87% of the wives indicated that religious beliefs were considered important. The average couple had employed the rhythm method for 4 years and 9 months at the time of the survey. Independently, both husbands and wives completed a Byrne's Revised Repression-Sensitization scale, Rotter's I-E scale, and Attitude Toward Sex scale, a Reaction to the Temperature-Rhythm Method scale, and a sexual behavior inventory. Data indicated that the rhythm method was acceptable despite difficulties with periods of abstinence, with 84% regarding abstinence as relatively difficult or very diffiucult. Other results indicated that there was a relatively low response concordance between husbands and wives, and that couples who had pregnancies with the method or had abandoned the method had more liberal sexual attitudes than those who did not have pregnancies and continued the method. 相似文献

Though often conflated, informal physical exercise and organized athletic participation have very different implications for adolescent sexual risk outcomes. The purpose of this research is to disaggregate strenuous exercise from sports, examine how each is associated with sexual risk, and explain the observed differences using the conceptual lens of cultural resource theory. Using a nationally representative sample of over 16,000 public and private high school students, we employ logistic regression to test hypotheses about the gender-specific and race-specific effects of strenuous exercise and athletic participation on adolescent sexual risk behavior. The results show that both forms of physical activity buffer sexual risk for girls. Strenuous exercise is associated with increased odds of sexual risk for boys. Sports and race interact to influence boys' sexual risk outcomes: Athletic participation is associated with lowered odds of sexual risk for white male adolescents, but heightened odds of sexual risk for black male adolescents. 相似文献

This study examines the relationship between socialist ideology and the current negative health lifestyles of the Russian population. We explore the possibility that Soviet-style socialism with its negation of individuality and individual initiative in health matters promoted the development of a passive orientation toward healthy living. Using a national sample, we compare the health practices of those Russians who wish to return to socialism as it was before Gorbachev to those of Russians who favor staying with the present political and economic course or adopting other reforms. If a socialist ideology has indeed fostered a lack of responsibility for individual health promotion in Russia today, those persons wishing to return to socialism would be less likely to adopt a positive health lifestyle. Our data show that this is indeed the case, as pro-socialist respondents demonstrate less activity toward achieving health than antisocialists--although neither group collectively practices a healthy way of life. 相似文献

The concept of 'identity' is central to much contemporary sociology, reflecting a crisis that manifests itself in two ways. Firstly, there is a view that identity is both vital and problematic in this period of high modernity. Secondly, while this awareness is reflected in sociology, its accounts of identity are inconsistent, under-theorized and incapable of bearing the analytical load required. As a result, there is an inherent contradiction between a valuing of identity as so fundamental as to be crucial to personal well-being, and a theorization of 'identity' that sees it as something constructed, fluid, multiple, impermanent and fragmentary. The contemporary crisis of identity thus expresses itself as both a crisis of society, and a crisis of theory. This paper explores the diverse ways in which 'identity' is deployed before turning to case-studies of its use by Anthony Giddens and Manuel Castells. This strategy demonstrates the widespread and diverse concern with identity before exploring how problematic it has become, even in the work of two of the world's leading sociologists. 相似文献

Researchers have noted that with the onset of adolescence, girls' voices become muted and school achievement drops. Girls learn that the expression of strong feelings leads to distance from others, and that full use of their bodies and minds cause others discomfort. Self-esteem suffers and girls become at risk for destructive behaviors. Most studies have been done with middle class Caucasian girls. Those few studies done with young girls of color speak of girls on the margin who seem to resist losing their voices and their self-esteem. This article describes a study involving 5th–8th grade girls participating in an Advisory group program at a grammar school in a predominantly Mexican community of a large city. Group sessions were taped and analyzed for common themes including voice and self-esteem. Focus was directed to the influence of the bicultural/bilingual environment in analysis of group content. Implications for practice are included. 相似文献

A random sample of more than 10,000 undergraduate students, selected from 119 4-year colleges, answered a mailed questionnaire about gun possession and gun threats. Approximately 4.3% of the students reported that they had a working firearm at college, and 1.6% of them have been threatened with a gun while at school. Students are more likely to have a firearm at college and to be threatened with a gun while at college if they are male, live off campus, binge drink, engage in risky and aggressive behavior after drinking, and attend institutions in regions of the United States where household firearm prevalence is high. Having a firearm for protection is also strongly associated with being threatened with a gun while at college. Students who reported having firearms at college disproportionately reported that they engaged in behaviors that put themselves and others at risk for injury. 相似文献
