This article considers the legal status of so-called contracts for anonymity between fertility clinics and donors of gametes that were made in the period before legislation authorising disclosure. It notes that while clinics frequently cite the existence of these "contracts" to argue against retrospective legislation authorising disclosure of the donor's identity, they may be nothing more than one-sided statements of informed consent. However, the article notes that even if an agreement between a donor and a clinic is not contractual, it does not follow that a person conceived through assisted reproductive technology has any right of access to the identity of the donor. The writer has not been able to locate examples of written promises by the clinics promising anonymity. There are written promises by the donors not to seek the identity of the recipients. These promises do not bind the resulting offspring nor do they appear to be supported by consideration. The article suggests that the basis for any individual donor to restrain a clinic from revealing their identity may be found in promissory estoppel. Nevertheless, there is no real issue in Australia concerning clinics revealing these details absent legislative authority. The issue is whether parliaments will legislate to authorise the disclosure. The article notes that it would be rare for parliaments to legislate to overturn existing legal contracts but suggests that the contract argument may not be as strong as has been thought.  相似文献

Abstract

This article reports on a reconnaissance of information systems containing data on the beneficiaries of direct and indirect federal housing expenditures. It covers data in the U.S. Departments of Agriculture, Housing and Urban Development, Veterans Affairs, and the Treasury; the Resolution Trust Corporation; financial regulatory agencies; and secondary mortgage market actors.

Data varied widely across agencies in availability, accessibility, and quality. Data are more systematically collected for low‐income beneficiaries of housing programs than for the more affluent beneficiaries of indirect housing expenditures. The systems need improvements in data quality and coverage and database format, though they have improved recently. Many research topics can be explored with new and underused data systems: the characteristics of beneficiaries of rural housing programs, urban rental housing programs, low‐income homeownership programs, and mortgage guarantee and insurance programs. But the lack of information on the systems themselves makes data difficult to locate and access.  相似文献

There has been a great deal of research concerning the effect of aestheticism on men in the late nineteenth century, especially in terms of their sexuality, but its impact on women has been largely dismissed as unnecessary, as women were naturally ‘feminine’. This article examines whether ‘the self-absorption and heightened emotional life of Aestheticism’ (J.B. Bullen, 1998 [Oxford: Oxford University Press]) was tolerable in women or if it was leading to disease, decay and corruption. Aestheticism's insistence on individuality and self-discovery were to have important consequences for women, fuelling the desire for a life of their own rather than solely service to others.  相似文献

Early adolescence is a period of the life course involving high levels of challenge that are stressful for some, perhaps resulting in depressive symptoms. In this study, adolescents were divided into four groups based on indices of depression and negative life events. Group differences in coping style, mastery, optimism, and social resources as well as group differences in patterns of change were investigated. Participants were 458 adolescents in sixth and seventh grade from a rural working class community. Subjects were assessed twice over a one-year period. Analyses revealed that the four groups were characterized by different levels of coping and social resources. Asymptomatic youth reported higher levels of optimism, mastery, active coping, and more positive relationships with parents and peers than did symptomatic adolescents. These same characteristics distinguished the resilient adolescents from the vulnerable adolescents, suggesting potential stress-buffering effects. One year later, the adolescents who were low on both depressive symptoms and negative life events continued to report more individual and contextual resources than the adolescents in the other groups.This research was supported by a grant from the William T. Grant Foundation (8912789) to Anne C. Petersen, Principal Investigator.

Research interests include biopsychosocial development at adolescence, adolescent depression and interventions to prevent it, gender issues, and developmental methodology.  相似文献

This article describes a questionnaire measure of self-image designed for young adolescents. It represents a downward extension of the Offer Self-Image Questionnaire and utilizes nine scales from that instrument: Emotional Tone, Impulse Control, Body Image, Peer Relationships, Family Relationships, Mastery and Coping, Vocational/Educational Goals, Psychopathology, and Superior Adjustment. This 98-item questionnaire elicits responses on a 6-point Likert-type scale. The alpha coefficients for each scale are high, indicating a high degree of internal consistency among the items. The validity of this instrument is examined through factor analyses and through the association of these scales with other measures of self-image. The results suggest that this questionnaire provides a useful way to assess self-image among young adolescents.This research was supported by Grant MH 30252/38142 to Anne Petersen.Received Ph.D. from the University of Chicago in 1973. Research interest is biopsychosocial development in adolescence, with a focus on sex differences.Research interests are vocational development and contextual influences on development in early adolescence.Research interests are the influences of adolescent and parent development on family relationships.Received M.D. from the University of Chicago. Research interests are the psychology and psychopathology of adolescents.Current research interests are social cognition and peer relationships during early adolescence.  相似文献

ABSTRACT: A 25-year-old woman being treated for non-Hodgkin's lymphoma was accidentally given vindesine intrathecally. The error was recognized immediately and a spinal cord washing was performed through syringing with isotonic saline. However, the patient died 6 weeks later with increasing paralysis, which was followed by neurologic failure. The deceased was autopsied and the central nervous system was removed for a microscopic examination. The results showed microscopic lesions extending from the lumbar to the thoracic portion of the spinal cord, which included pseudocystic transformation of the cells, degeneration of myelin, and microhemorrhages. The brain was edematous and, in the cerebellum, the vermis showed a loss of granule and Purkinje cells. The authors compare this report on vindesine toxicity with cases in the literature involving vincristine. The treating physician admitted responsibility and was sentenced to both a fine and imprisonment.  相似文献
