In spite of numerous recent outcome studies of extremely low birth weight (ELBW) infants, no data exist on their development prior to term. In this study we traced and compared the neurobehavioral development of 251 ELBW (< 1,000 g) and 240 low birth weight (LBW; 1,000 g–2,500 g) preterms born between 1995 and 2004 from 32 to 37 weeks postconceptional age (PCA), using the Neurobehavioral Assessment of the Preterm Infant (NAPI Korner & Thom, 1990). Compared to the original NAPI cohort of 521 infants (born 1983–1989), the ELBW and LBW infants were at higher medical risk, displayed weaker motor development, a tighter scarf sign and popliteal angle at all or most PCAs, and a weaker cry at older PCAs; they did not differ in irritability and percent asleep ratings. Few differences were noted between the ELBW and LBW groups. Research is now needed to determine whether the 1995 to 2004 NAPI values of ELBW and LBW infants at 32 to 37 weeks PCA are predictive of later outcome of high‐risk preterms.  相似文献

关联理论是近年来西方影响很大的认知语用学理论。众所周知,由于文化的差异,隐喻的意义是不确定的,因而翻译时很难处理得当,文章试图从一个全新的视角——关联的角度对这一问题进行探讨。  相似文献

This report presents salient issues for therapists in understanding and treating the remarried (Rem, second, blended, reconstituted or step) family. The structure of the remarried family is differentiated from that of the intact family. Specific treatment goals for Rem families are elaborated and various treatment modalities advocated. The need to include former spouses and to consider the meta family system are discussed. Common reactions and difficulties engendered in therapists when working with Rem systems are explicated.  相似文献

Summary.  We compare two different multilevel modelling approaches to the analysis of repeated measures data to assess the effect of mother level characteristics on women's use of prenatal care services in Uttar Pradesh, India. We apply univariate multilevel models to our data and find that the model assumptions are severely violated and the parameter estimates are not stable, particularly for the mother level random effect. To overcome this we apply a multivariate multilevel model. The correlation structure shows that, once the decision has been made regarding use of antenatal care by the mother for her first observed birth in the data, she does not tend to change this decision for higher order births.  相似文献

Five experienced Australian and New Zealand family therapists and trainers seek to answer the question: ‘What key concepts and core learnings should be part of any family therapy training course?’ They debate the usefulness of making ‘shopping lists’ of core concepts, the importance of considering trainers' and trainees' contexts in the formation of their values and perspectives, and the distinctive role of Family of Origin work in training, clarifying central themes. Three experienced trainers respond to the issues raised.  相似文献

Minnesota youth (15 to 18-years of age) were surveyed regarding their gambling experiences and psychosocial risk status. Gambling was reported by most of the subjects, with 8.7% classified as problem gamblers. Correlates of problem gambling included school difficulties, regular drug use, delinquency, parental gambling, and being male. Adolescent gambling is conceptualized as a normal experience of youth, yet those in the problem gambling group may be particularly vulnerable to future gambling problems.The authors would like to express their gratitude to the Minnesota Department of Human Services for their funding support of the study and to several colleagues, particularly Linda Harris, J. Clark Laundergan and Durand Jacobs, and anonymous reviewers for their helpful comments.  相似文献

School-age pregnancy is a major social problem that affects youth, families and communities. The complexities of school-age pregnancy demand that social work practitioners have knowledge across diverse fields and keep abreast of changing sociopolitical trends. Information clearning-houses have been developed to assist practitioners in their efforts to keep abreast of a particular field of practice. This paper identifies major national information clearinghouses that provide resources for practitioners who work in the field of school-age pregnancy and prevention.  相似文献

The Milan model relies upon careful hypothesising, a therapeutic stance of neutrality and circular questioning on the part of the therapist in order to release new information into the family system. Current thinking incorporates a postmodernist perspective which challenges the traditional process of hypothesising. This postmodern challenge is in part due to the use of the term ‘hypothesising’ which is strongly associated with reductionism or structuralism, which relies on the scientific method. As a clinical activity, the actual process of hypothesising is a complex, cognitive task and often a relatively unpopular activity which is difficult to teach to students. This paper discusses the therapeutic benefits and limitations of hypothesising and proposes a structure for teaching hypothesising to students learning to work with couples from a post-Milan perspective.  相似文献
