Longitudinal data were analyzed for seminal characteristics of rhesus monkeys and beagles. The monkeys were exposed to DBCP; the beagles were exposed to acute or chronic whole body gamma irradiation. The semen was analyzed for volume and sperm concentration. Sperm were measured for percent motility, swimming speed, and head dimensions. Abnormalities of the sperm tail were also noted. All treatments resulted in measurable effects on the semen parameters. Sperm production, as evaluated by seminal sperm concentration or total sperm numbers in the ejaculate, was as informative of testicular toxicity as any other parameter or combination of parameters. A consistent finding was that changes in sperm output occurred concomitantly with changes in sperm motility. 相似文献

Although it is often assumed that food pantries are managed by middle‐class directors whose social background differs significantly from that of their target populations, no systematic empirical evidence concerning this issue exists to date. Moreover, scholarship has yet to explore the extent to which the presumably distinctive social positions of pantry directors and clients might result in the stigmatization of poverty, social welfare programs, and the poor by agency directors. Drawing on insights from attribution theory, this study seeks to shed light on demographic and attitudinal differences between pantry directors and food‐needy persons. The study begins by comparing the demographic characteristics of food pantry directors in a two‐state region of the South (Alabama‐Mississippi) with those of the food‐needy population in the region. It then moves on to contrast attitudinal disparities between these directors and food‐needy persons related to such issues as the causes of poverty, the effects of social welfare programs, and the character of those who utilize food assistance programs. Noteworthy differences in race, education, and religiosity emerge when comparing directors with the populations they serve; however, directors did not differ markedly from their potential clients in key social attitudes. When asked specifically about food pantry clients, directors responded with a mix of sympathy and suspicion. While a substantial portion of directors attribute poverty to structural causes, a significant number also characterize clients seeking food assistance as possibly having unsavory motivations for doing so. The study concludes with a discussion of the implications of these findings. 相似文献

This paper examines the sleep disruption experienced by 36 families of technology‐dependent children living at home in the United Kingdom. The paper begins with an overview of the qualitative study in which parents' experiences of sleep disruption emerged as a major theme. We then describe the nature of and reasons for the sleep disruption, the help families received with care overnight, and the effects of sleep disruption on parents in particular. This is followed by discussion of the implications of the findings for policy and practice as well as future research. 相似文献

In all cases of newborn adoption where placement is made directly into the permanent adoptive home, the adoptive parents become the psychological parents for that child. While birth parents give the gift of birth, they do not experience the developmental process of being a parent because in reality they are emotionally unprepared for this responsibility. We discuss the clinical meaning of a voluntary termination of parental rights, the appropriate grieving of the real narcissistic loss of the baby, and the meaning of adoption for a birth parent.There is a new trend in the field of child welfare toward openness in adoption which purports to change traditional confidential adoptions. We discuss the crucial aspects of the intrapsychic difference for a birth parent experiencing an open or confidential adoption.This paper was presented to the National Committee for Adoption, Convention, October, 1982: the First International Conference on Pediatric Social Work, August, 1982 and to the Child Care Association of Illinois Convention, April, 1982.

In all cases of newborn adoption where placement is made directly into the permanent adoptive home, the adoptive parents become the psychological parents for that child. While adoptive parents enter the development phase of parenthood, the task is complicated by the fact that the child they are about to raise is not their biological child. We discuss the biological and psychological foundations of parenthood and examine the tasks that adoptive parents face when confronted with either an open or confidential adoption. We focus on the ways in which either procedure may assist or disrupt the adoptive parents' ability to form and maintain an on-going healthy attachment to the child.There is a new trend in the field of child welfare toward openness in adoption, which purports to change traditional confidential adoptions.
