One's attitudes toward love and sexuality are influenced by many factors, including gender. To explore the role of gender (and other variables) in participants' attitudinal orientations toward love and sexuality, data were collected in the United States at three time points (1988, 1992, 1993), resulting in a total sample of 1,090 participants. Data analyses showed gender differences in both sexual attitudes and love. Men were more sexually permissive than women (consistent with previous research), although women and men similarly endorsed other aspects of sexuality, including sex as an emotional experience. Men and women differed on several relationship variables (e.g., women were more oriented to friendship-based love, and men to game-playing love). However, correlational analyses showed many similar patterns for women and men. These findings underline the need to consider both gender differences and similarities in sex and love within intimate relationships.  相似文献

Friend support is often assumed to exert direct environmental influences on psychological distress, yet the role of both genetic and environmental influences on this association has not been examined. This study investigates whether both genetic and environmental factors explain the link between friend support and psychological distress in adults. The sample was drawn from the Midlife Development in the United States study and included 947 pairs of monozygotic, same‐sex dizygotic (DZ), and opposite‐sex DZ twins. Results showed that genetic influences explain the association between friend support and psychological distress, suggesting that heritable contributions to friend support also shape psychological distress. Interventions focused on psychological distress should consider how individuals' heritable characteristics influence their friend support and psychological distress.  相似文献

The public do not like, and we do not like the idea of designer babies (Ruth Deech, then Chair of the Human Fertilisation and Embryology Authority, quoted in The Independent, 18 October 2000). We are all on the slippery slope-the question we should be asking is: skis or crampons (Professor John Harris, The Centre for Social Ethics and Policy, University of Manchester, in an interview with Susan Johnson). LINGUISTIC AND CULTURAL GROUNDING OF THE DESIGNER BABY DEBATE In October 2000, news was released of the world’s first ‘designer baby’—Adam Nash who was born on 29 August 2000 in the United States. He was chosen as a donor for his sister Molly, who suffered with Fanconi Anaemia, which is a rare genetic disease. Without a bone marrow transplant, Molly would have died before the age of 10. A suitable donor had not been found, so her parents decided to undergo in vitro fertilization (IVF), and preimplantation genetic diagnosis (PGD) to select an embryo that would not carry the disease-causing gene and would become a brother and a donor for Molly. At the time of his birth, Adam’s cord blood was collected and later transplanted into his sister. Initial reports suggest that the treatment has been successful.  相似文献
