Abstract: The purpose of this paper is to determine whether divorced parents exhibit a diminished capacity to parent in the period following divorce. Using 2 waves of data from a national survey of Canadian children, the current study prospectively follows 5,004 children living in 2–biological parent households at initial interview and compares changes in parenting practices between households that subsequently divorce and those that remain intact. Results show that divorce is unrelated to changes in parenting behavior, suggesting that there are more similarities than differences in parenting among recently divorced and continuously married parents. 相似文献

The Sinding-Larsen and Johansson disease is a non-negligible cause of gonalgia among children of 10 to 14, often misinterpreted as « growing pain . The disease is a benign pathology of the lower pole of the patella which occurs preferentially in physically active children. Our study, carried out in conjunction with the medical department INSEP, is based on a literature review as well as an analysis of 14 cases over two years. The present work eventually led to the differentiation of four etiopathological categories accounting for all the radiochemical evolutions observed. At the origin of these four categories, two factors coexist: the local fragility (the presence of cartilage at the lower pole of the patella) and the trigerring factor, which is most often sports practice. This explains why among children practicing sports, even intensively, only few suffer from this disease.It is essential to know the different radiological aspects of the normal patella in children, in order not to misinterpret one of these aspects with the Sinding-Larsen and Johansson disease.Always benign, the Sinding-Larsen and Johansson disease can very seriously disturb the « careerof children, engaged in high-level sports activity, the average time of evolution being seven months. 相似文献

吉林省经七年来的鼠情监测,基本查清与人们接触密切的鼠类,特别是传播疾病的主要鼠类的分布规律,分析出我省家鼠有两个高峰(6月和10~11月),野鼠也有两个高峰(6月和10月),这与我省流行性出血热两个高峰相吻合,鼠峰在病峰之前。1986年以后,由于我省开展大规模灭家鼠活动,家鼠高峰已不存在规律性。通过几年来的灭鼠活动,使家鼠密度呈下降趋势,城镇褐家鼠和小家鼠构成比发生变化。城镇未爆发家鼠型流行性出血热。鼠情监测为灭鼠防病工作提供了科学依据。 相似文献

公共服务体系是现代文明社会的基本标志,也是现代社会稳定发展的基础,公共经济学和欧美国家的发展经验已经证明了这一点。韩国是从上世纪80年代取得“汉江奇迹”后,在经济增长成就和产生的社会问题的双重推动下,开始了以奉侍型政府、国民中心等为目标的管理改革,并逐步建立起比较完善的公共服务体系。中国在进入新世纪后提出建设服务型政府,开始建立和完善公共服务体系。研究表明,在建立公共服务型政府的改革中,两国在价值理念、改革目标、改革路径和举措等方面都有许多相同相似的方面,但也存在差异性。总体上,韩国在建立公共服务型政府,提高公共服务质量等方面要比中国先行一步,有许多值得中国政府学习和借鉴的地方。 相似文献

本文通过对动物细胞培养过程中pH值和溶氧(DO)水平控制要求的分析,设计了用空气、氧气、氮气和二氮化碳四组气体关联控制pH值和DO水平的控制系统。该系统根据对瞬时pH值和DO值参数的检测,通过微处理机进行一系列的逻辑判断和具有PI调节规律的DDC增量词节计算,再经四气体关联互补计算和多重时序控制环节,综合调节四组气体电磁阀的相互开闭时间,实现对培养过程中pH值和DO水平的控制,满足动物细胞生长的需要。 相似文献

Reported herein is a case of hydrops fetalis in which the cord blood expressed cytomegalovirus (CMV) antigen. Fetal ascites was removed from an infected fetus with hydrops in utero and 2.5 g CMV hyperimmunoglobulin was administered into the fetal abdominal cavity at 28 weeks gestation. After immunoglobulin administration, fetal ascites vanished, preload index of the inferior vena cava decreased and platelet count of the infant increased. However, despite intrauterine therapy and intensive neonatal care, the infant died soon after birth. The expression of CMV antigen in the nucleus of polymorphonuclear leukocytes in fetal cord blood indicated that the fetal hydrops was caused by CMV infection. When symptomatic CMV infection of a fetus is suspected from serological and ultrasound findings, further examinations should be performed for the diagnosis. Intrauterine immunoglobulin therapy could be one of the therapeutic options for the affected fetus. 相似文献

Oligonol is produced from the oligomerization of polyphenols (typically proanthocyanidin from a variety of fruits such as lychees, grapes, apples, persimmons, etc.) and contains catechin-type monomers and oligomers of proanthocyanidins. The ability of Oligonol to affect infection-dependent eye inflammation, locomotion and longevity in senescence-accelerated prone mice (SAMP8) (a model of senescence acceleration and geriatric disorders with increased oxidative stress and neuronal deficit) was investigated. Oligonol (60mg/kg) significantly modulated the extent of inflammation scores in the eye of SAMP8 mice. Examination of the mice indicated infection with mouse hepatitis virus and pinworm (Syphacia obvelata) in both males and females and with the intestinal protozoa (trichomonad) in males. A comparison of the two groups (using log-rank test) and the difference in the mean life span between groups (using Student's t-test) indicated significant differences in survival (p=0.043) and the mean life span (p=0.033) in male SAMP8 mice. Oligonol increased the mean life span and this was statistically significant. In the open-field locomotive test, the 7-week-old SAMP8 mice crossed more than 40 partitioned lines in 1min. At 48-week-old control untreated male SAMP8 crossed 2 lines. The Oligonol-treated 48-week-old male SAMP8 mice crossed 17 lines however. The improved locomotive activity was statistically significant even after 36weeks in the Oligonol-treated male SAMP8 but this was not the case throughout the time course of the study in the Oligonol-treated female SAMP8. Thus Oligonol treatment to SAMP8 mice modulated the severity of infection-dependent inflammation, prolonged life-span and significantly improved locomotive activity indicating potential benefit to aging-associated diseases such as Alzheimer's or Parkinson's diseases. This presents potential for further research to define infection-dependent inflammation associated with degenerative conditions and the molecular mechanism of dietary antioxidant protection. 相似文献
