The present report describes the organization and operation of a community based venereal disease clinic designed to meet the particular needs of homosexual men. Male same‐sex contact is seen as an important factor in the epidemiology of venereal disease and the community based clinic is described as a potentially important mechanism for control of the disease. Socio‐medical characteristics of male homosexual patients are described. Data are offered to document the prevalence of asymptomatic gonorrhea and the need for screening of atypical sites in this population. 相似文献

Abstract Although audio-visual materials are commonly used on college and university campuses, frequently those materials are not evaluated to determine what impact they may have on students' attitudes. The present research compared the effect of three audio-visual programs on attitudes of college students toward homosexuality. The three programs included a film that dealt with prejudice towards numerous groups but not towards homosexuals; a video-tape of a homosexual clergyman who discussed sexual variance with particular emphasis on homosexuality; and two films in which couples were explicitly engaging in homosexual behavior. A control group was used. All groups received a lecture about homosexuality. Using a two-way analysis of covariance, significant differences were found among the groups. Subjects that watched the film on prejudice and the video-tape of a discussion of homosexuality, as well as the control group, were all significantly more tolerant toward homosexuality than subjects who watched the explicit films. The difference among groups was immediate only. Five weeks after exposure to audio-visual programs, there were no significant differences. There was no significant difference between males and females, either immediately after seeing the programs or five weeks later. Thus, attitudes of college students toward homosexuality can be altered and were not gender specific. 相似文献

Rapid expansion of educational research and conceptualization combined with increased emphasis on relevance and effectiveness as values within the educational institution encourage expansion of the assumptions made by social work educators. Such expansion forces recognition of the complexity of the educational transaction and of the importance of flexibility as a teacher characteristic. But certain new assumptions suggest undeveloped opportunities for facilitating significant student learning. This article identifies four such opportunities based on assumptions about individual differences, cognitive functioning, and affective learning. A complex, growth-oriented view of social work education is emphasized. 相似文献

Earlier attempts at reconciling disparate substitution elasticity estimates examined differences in separability hypotheses, data bases, and estimation techniques, as well as methods employed to construct capital service prices. Although these studies showed that differences in elasticity estimates between two or three studies may be attributable to the aforementioned features of the econometric models, they have been unable to demonstrate this link statistically and establish the existence of systematic relationships between features of the econometric models and the perception of production technologies generated by those models. Using sectoral data covering the entire production side of the U.S. economy, we estimate 34 production models for alternative definitions of the capital service price. We employ substitution elasticities calculated from these models as dependent variables in the statistical search for systematic relationships between features of the econometric models and perceptions of the sectoral technology as characterized by the elasticities. Statistically significant systematic effects are found between the monotonicity and concavity properties of the cost functions and service price–technical change specifications as well as between substitution elasticities. 相似文献

Abstract This study examines variation in filial responsibility expectations-the extent to which adult children are expected to assist and care for their aging parents-among a sample of 440 older persons. The analysis focuses on the relationship of filial responsibility expectations to residential location and tests the hypothesis that older rural residents have higher expectations for assistance from their children than do older urbanites. Current residential location is found to have little impact on expectations, but older persons who were raised in rural areas, particularly on farms, have significantly higher expectations for filial assistance than do older persons from urban backgrounds. Possible consequences of these patterns for the transmission of expectations from parents to children are discussed. 相似文献

Using a spatially extensive urban database constructed from the Maryland Biological Stream Survey (MBSS), we describe the
relationships of nutrients in small-order streams to eight defined categories of percent catchment urbanization, correlations
between chloride and conductivity in urban streams, and relationships between nutrients and chloride with two Maryland-specific
indices of biotic integrity for benthic macroinvertebrates and fish assemblages. Stream nutrients become elevated with increasing
percent catchment urbanization, followed by increases in all four measured nitrogen species and total phosphorus at catchment
urbanization levels greater than 10%. There was a strong collinear relationship (r
2 = 0.90) between chloride and conductivity (trimeans) across all eight urbanization classes, where Cl (mg/L) = −0.397 + 0.188*conductivity
(μS/cm). Critical values for all water quality parameters with the two Maryland biological indices were derived using quantile
regression, with significant regressions developed for 11 of 16 water quality parameters and the two biotic indices. For nitrate
(NO3-N), the critical thresholds between fair and poor stream quality for the two Maryland biological indices were 0.83 mg/L (benthic
macroinvertebrate assemblages) and 0.86 mg/L (fish assemblages). Increasing stream nutrient and chloride levels, associated
with widespread catchment urbanization intensity, now affect many small streams in Maryland, with implications for decreasing
water quality in major tributaries and the Chesapeake Bay. 相似文献

Raymond L. Schmitt 《Symbolic Interaction》1991,14(3):237-259
The introduction of “replacement” teams for the first time in the NFL provided an opportunity to investigate how controversial social definitions and the meaning of such frames emerge within a modern social world. Seven processes were identified: disrupting social worlds, experiencing social ambiguity, interpreting disruption institutionally, socially constructing laminations, disattending problematics of laminations, culturally adapting to anomaly, and negating collective protest. Conclusions are based on an emergent content analysis of extensive newspaper, sport and newsmagazine, and live television and radio accounts. The value of Goffman's framing ideas for symbolic interactionism is discussed. 相似文献
