Independent learning among general practice trainees: an initial survey

Self-directed learning is a natural way for adults to learn. Vocational training for general practice is a preparation for unsupervised clinical work that will be supported, in the main, by continuing medical education. This study uses the Self-Directed Learning Readiness Scale to investigate factors influencing readiness for such learning among a sample of general practice trainees. Three principal factors emerged from analysis: enjoyment and enthusiasm for learning; a positive self-concept as a learner and a factor suggesting the possibility of a 'reproducing' orientation to learning. These factors may reflect approaches to learning in general rather than these adopted for professional learning, but offer helpful pointers for the development of both vocational training and of continuing medical education.     

青少年精神分裂症患者家庭因素的研究

目的:探讨青少年精神分裂症患者的发病和家庭因素的相关性.方法:采用父母养育方式评价量表(EMBU)及家庭环境量表中文版(FES-CV)对60名青少年精神分裂症患者进行测评并与60名健康青少年进行对照及相关分析.结果:青少年精神分裂症患者父母养育方式与正常组对照显示:其父亲惩罚严厉、拒绝否认因子分显著高于对照组,情感温暖、理解因子分显著低于对照组(P＜0.05或P＜0.01);其母亲过分干涉过度保护、偏爱被试因子分显著高于对照组;母亲的情感温暖理解、过度保护、偏爱被试因子分高于父亲(P＜0.05或P＜0.01).家庭环境的亲密度、情感表达、文化性、娱乐性的因子分低于对照组,矛盾性和控制性均高于对照组(P＜0.05或P＜0.01).相关分析显示:父亲过度保护与母亲拒绝否认,及母亲过度保护与父亲拒绝否认因子之间呈负相关(r≥0.8);父亲与母亲EMBU相同因子得分具有相关关系(r≥0.6).结论:不良的家庭环境和父母养育方式对青少年精神分裂症的发病起一定作用,具有相关性.     

Induced abortion in China and the advances of post abortion family planning service

<正>This is a review of current situation of induced abortion and post abortion family planning service in China. Induced abortion is an important issue in reproductive health. This article reviewed the distribution of induced abortion in various time, areas, and population in China, and explored the character, reason, and harm to reproductive health of induced abortion. Furthermore, this article introduces the concept of Quality of Care Program in Family Planning, and discusses how important and necessary it is to introduce Quality of Care Program in Family Planning to China.     

胃癌组织中核基质蛋白的变化

目的：研究胃癌组织核基质蛋白的改变。方法：应用SDS－PAGE技术及Geneools定量分析软件，对22例胃癌组织及正常组织的核心基质蛋白进行了研究，结果：胃癌组织与正常组织比较，Mr为30000，28000的核基质蛋白表达量明显减少（P＜0．05），不同分化类型及不同临床分期胃癌组织间比较，此种核基质蛋白表达量差异无统计学意义（P＞0．05），结论：胃癌组织中核基质蛋白的改变可能在肿瘤的早期已经发生，是胃癌发生的早期分子事件。     

Cerebellar nuclear afferents--where do they originate? A re-evaluation of the projections from some lower brain stem nuclei

Summary Cerebellar nuclear afferents from some caudal brain stem nuclei in the cat were studied by means of retrograde transport after implantation of the wheat germ agglutinin-horseradish peroxidase complex in crystalline form in the cerebellar nuclei. The findings give evidence that projections to the cerebellar nuclei from certain nuclei of the reticular formation proper (e.g., from the gigantocellular reticular nucleus) are very modest, while there appears to be no or extremely few cerebellar nuclear afferents from the paramedian reticular, spinal trigeminal, gracile, cuneate and external cuneate nuclei. Previous tracer studies have given evidence that also the pontine and red nuclei send very few, if any, fibres to the cerebellar nuclei. All these brain stem regions are known to project to the cerebellar cortex. This relative lack of mossy fibre collaterals to the cerebellar nuclei is discussed with references to previous literature on the distribution of cerebellar nuclear afferents, and the problem of how the cerebellar nuclei are facilitated is considered.Abbreviations Br.c. superior cerebellar peduncle (brachium conjunctivum) - Br.p. middle cerebellar peduncle (brachium pontis) - C.r. interior cerebellar peduncle (restiform body) - HRP horseradish peroxidase - L left - N.c. cuneate nucleus - N.c.e. external cuneate nucleus - N.c.t. nucleus of corpus trapezoideum - NIA anterior interposed nucleus - NIP posterior interposed nucleus - NL lateral (dentate) nucleus - N.l.l. nuclei of lateral lemniscus - NM medial (fastigial) nucleus - N.m.X. dorsal motor vagal nucleus - N.mes. mesencephalic trigeminal nucleus - N.r.l. lateral reticular nucleus (nucleus of the lateral funiculus) - N.r.p. paramedian reticular nucleus - N.r.t. reticular tegmental pontine nucleus - N V, VI, VII, XII root fibres of cranial nerves - Ol.s. superior olive - P.h. nucleus praepositus hypoglossi - Py pyramid - R right - R.gc. gigantocellular reticular nucleus - R.l. lateral reticular nucleus of Meessen and Olszewski - R.p.c. caudal pontine reticular nucleus - R.pc. parvicellular reticular nucleus - R.v. ventral reticular nucleus - Tr.sp.V. spinal tract of the trigeminal nerve - T.s. solitary tract surrounded by nucleus of solitary tract - V.m. medial vestibular nucleus - WGA wheat germ agglutinin - WGA-HRP wheat germ agglutinin-horseradish peroxidase conjugate - V, VI, VII, X, XII motor nuclei of cranial nerves     

Through pragmatic eyes: philosophy and the re-sourcing of family nursing

Abstract   This paper explores the integral relationship between philosophy and nursing practice. The discussion begins by suggesting that philosophy is more than a set of abstract ideas or an intellectual activity; that it is a way of living and being in practice. The author contends that philosophical inquiry can improve the adequacy and relevance of family and nursing theories by promoting the examination and expansion of those theories in light of the experiences and intuitions of nurses. Offering a personal example the author exemplifies how philosophical activity can directly and experientially enhance everyday nursing practice.     

Leukemia clusters around nuclear facilities in Britain

He bas been retained for the defense by British Nuclear Fuelsplc in two suits in which leukemia and non-Hodgkin's lymphoma have been alleged to result from radiation exposures due to the operation of the nuclear reprocessing plant at Sellafield. This paper has been sent to the senior authors of the papers reporting clusters of leukemia or other malignancy in the vicinity of nuclear facilities in Britain and their comments invited. Subject to considerations of space and CCC style, these comments will be published as submited.

Familial and socioeconomic influences on children''s well-being: An examination of preschool children in Kenya

As patterns of family formation change, it is important to know how children's lives are affected by their parents' marital and socioeconomic circumstances. Using data from the 1993 Kenya Demographic and Health Survey, this study shows that children of never married and formerly married mothers have significantly higher probabilities of polio dropout and acute undernutrition than those of monogamously married mothers. The number of male household members of working age greatly enhances the chances of full immunization and the nutritional status of children whose mothers were previously married. For children of never married mothers, the benefits of residing with males of working age are largely a function of ethnicity. The results also show that, although children are not disadvantaged nutritionally when their fathers have more than one wife, polygyny is associated with a higher probability of polio dropout and lower probability of full immunization than monogamy. Higher socioeconomic status is associated with a greater probability of full immunization and a lower probability of malnutrition but socioeconomic factors do not explain the effects of mothers' marital status. The findings underscore the complex realities of family interaction and the importance of the broader social context in accounting for variations in child welfare across diverse marital situations.
