Nationally representative data from the General Social Surveys indicate that from 1988 to 1998 there was an increasing likelihood that American men and women had had a same‐gender sexual partner during the previous year. Increases in same‐gender sexual partnering and decreases in exclusively opposite‐gender sexual partnering during the previous 5 years were also evident among women over the 1988–1998 period. Same‐gender sexual partnering was found to be associated with age, birth cohort, race, size of hometown at age 16, and mothers’ education. The increase in same‐gender sexual partnering over the 1988–1998 period persisted after controlling for these factors. Several possible explanations for the trend are discussed.  相似文献

The basic premise of running a field trial is that the estimates of treatment effects obtained are representative of how the different treatments will perform in the field. The disparities between the treatment effects observed experimentally, and those that would be observed were the treatments applied to the field, we term 'representation bias.' When looking at field trials testing the efficacies of treatment sprays on plant pathogens, representation bias can be caused by positive and negative inter-plot interference. The potential for such effects will be greatest when looking at pathogens that are dispersed by wind. In this paper, a computer simulation that simulates plant disease dispersal under such conditions is described. This program is used to quantify the amount of representation bias occurring in various experimental situations. Through this, the relationships between field design parameters and representation bias are explored, and the importance of plot dimension and spacing, as well as treatment to plot allocation, emphasized.  相似文献

Two successive terms of a New Labour government have requiredsocial work practice in the UK to occupy a particular publicpolicy context that is, at best, indifferent and, at worst,hostile to some of the professional interests and traditionalconstituencies of social workers. In this paper, the immediatepast editors of the Journal reflect on how social work has soughtto adapt and survive under these conditions, as revealed inthe papers published during the period of their stewardship.  相似文献

This study investigates infants’ discrimination abilities for familiar and unfamiliar regional English accents. Using a variation of the head‐turn preference procedure, 5‐month‐old infants demonstrated that they were able to distinguish between their own South‐West English accent and an unfamiliar Welsh English accent. However, this distinction was not seen when two unfamiliar accents (Welsh English and Scottish English) were presented to the infants, indicating they had not acquired the general ability to distinguish between regional varieties, but only the distinction between their home accent and unfamiliar regional variations. This ability was also confirmed with 7‐month‐olds, challenging recent claims that infants lose their sensitivity to dialects at around that age. Taken together, our results argue in favor of an early sensitivity to the intonation system of languages, and to the early learning of accent‐specific intonation and potentially segmental patterns. Implications for the development of accent normalization abilities are discussed.  相似文献

This essay considers Jessica Benjamin's conception of recognition and relationality, concentrating on the role of destruction and of dyadic relations. I argue that Benjamin has tended in her recent work to posit clinical practice as an area in which the destructiveness in relations can be transformed into more productive and even harmonious experiences of difference. Benjamin has also provided a dyadic alternative to the triangular conception of desire and relationality, offering an important alternative to schemes that are restricted to the oedipal model. I ask whether forms of triangulation are nevertheless central to the workings of desire that exceed the purview of Oedipus, in particular, whether understanding the coconstitutive relations of homosexuality and heterosexuality offer a queer approach to triangularity.  相似文献

This paper describes our involvement as jury consultants in one of the most notorious criminal trials in history—the McMartin child-molestation trial in Los Angeles. The McMartin trial was the longest and costliest criminal trial in American history. The prosecution spent $15 million and took nearly six years in making a criminal case against day-care workers, only to have the jurors declare them not guilty. The defendants in the McMartin trial were charged with molesting young children at a preschool in Manhattan Beach, Los Angeles County, California. In 1987, we had performed scientific defense voir dire jury selection to choose the most impartial jurors to try the two defendants, Raymond Buckey and Peggy Buckey McMartin. In performing scientific jury selection, both a community survey and pre-voir dire questionnaires served as an important empirical foundation to assess jurors’ attitudinal, demographic, and socioeconomic characteristics to develop the effective juror profiles for the trial. The authors received the 1994 Gustavus Myers Center Outstanding Book Award on Human Rights in North America.  相似文献
