Using data from the British Household Panel Survey and the National Survey of Families and Households in the United States, we present a sociodemographic profile of fathers and compare the determinants of absent fatherhood in each country. Although fatherhood has a younger profile in the United States, especially for blacks, predictors of fathers’ residency with their children are remarkably similar in the two countries. In both countries, the strongest predictor of a father’s absence is the parents’ relationship to each other at the time of the child’s birth. Policy implications of this finding are discussed.  相似文献

Summary.  Origin–destination statistics have been produced from the last three UK censuses. The paper describes what is new about the 2001 census interaction data on migration and commuting, considers the disclosure control methods that were applied to cells containing small values and demonstrates the problems that are associated with making comparisons with 1991 data. The effect of small cell adjustment procedures on the interaction data sets is investigated by means of selective analyses at different spatial scales. Some recommendations are made in light of the problems that were manifest in 2001.  相似文献

Cumulants, moments about zero, and central moments are obtained for the mean-corrected serial covariances and serial correlations for series realizations of length n from a white-noise Gaussian process. All first and second moments (and some third, fourth, and higher moments) are given explicitly for the serial covariances; and the corresponding moments for the serial correlations are derived either explicitly or implicitly.  相似文献

Where Would I Be Without You, the first and only poetry recording from Olivia Records, offers a glimpse into the powerful friendship and artistic collaboration between poets Pat Parker and Judy Grahn. Grahn and Parker met in Oakland, California in 1970, beginning an artistic collaboration and a powerful friendship that endured through Parker's death in 1989. Grahn's and Parker's work spread the good news of poetry; they were integral to how we lesbians imagined our voices in the world. The articles in this special issue reconsider and pay tribute to their work.  相似文献

BackgroundAccording to the psychoanalytical literature, it is during pregnancy that maternal representations of the mother–infant relationship become activated. Midwives who are engaged with the mother and the baby have not drawn upon this concept in their practice. In order for this to happen, it is important to understand better the nature of maternal representations and when they are activated from empirical studies.QuestionThe research question is: what are the maternal representations of a group of first time mothers from pre-pregnancy, early pregnancy and to the first ultrasound.MethodA narrative approach was used to gain insight into the maternal representations of first time pregnant womens’ account of their representations. The analysis method was based on thematic approach.ParticipantsFifteen women aged between 23 and 38 years.SettingA midwives clinic attached to a tertiary hospital in Melbourne, Australia.FindingsFirst-time pregnant women's maternal representations were activated when a woman begins to plan her pregnancy (‘the time is right’), again at the onset of physical changes to her body as a result of conception (‘my body is changing’), and at the first early ultrasound at around twelve weeks (‘it’ is a real baby).ConclusionMaternal representations are important for the midwife and pregnant women because this concept provides another understanding in relation to the psychological dimension of pregnancy.  相似文献

Recent policy has emphasized the need for advocacy services for children and young people, developments that have gone hand‐in‐hand with greater levels of participation of young people in decision‐making. Advocacy for disabled young people is especially important, as they are a particular vulnerable group and have, traditionally, been even more excluded from decisions about matters affecting their lives. This paper reports the findings, as they relate to disabled young people, from a study that investigated the role of advocacy for looked‐after children and children in need. The paper highlights some of the benefits of advocacy for disabled children, the dilemmas facing advocates between advocating and acting in someone's ‘best interests’, identifying the client and the boundaries between advocacy and social work. It argues that time given to establish a close relationship with a disabled child or young person is crucial if advocacy is to be effective and participation in decisions affecting their lives a reality.  相似文献

Previous research has identified methodological problems in the design and conduct of randomized trials that could, if left unaddressed, lead to biased results. In this report we discuss one such problem, inadequate control intervention, and argue that it can be by far the most important design characteristic of randomized trials in overestimating the effect of new treatments. Current guidelines for the design and reporting of randomized trials, such as the Consolidated Standards of Reporting Trials (CONSORT) statement, do not address the choice of the comparator intervention. We argue that an adequate control intervention can be selected if people designing a trial explicitly take into consideration the ethical principle of equipoise, also known as "the uncertainty principle."  相似文献
