Acute phase reactants, challenge in the near future of animal production and veterinary medicine

INTRODUCTION The systemic acute phase reaction known to occur on infection, inflammation, trauma, burns, ma- lignancies and tissue damage in general, has been studied by scientists from various disciplines. In the last decade, emphasis has been laid on application of blood tests for acute phase reactants to monitor ani-mal health in general, as well as for human patients suffering from specified classes of diseases (Gruys et al., 2005). However, basic mechanistic patterns as- sociated wit…     

Revealing the relation between temperament and behavior problem symptoms by eliminating measurement confounding: expert ratings and factor analyses

This study examined the hypothesis that item overlap, or measurement confounding, accounts for the correlation between temperament and behavior problem symptoms in children. First, a conceptual approach was taken in which 41 experts rated temperament (Children's Behavior Questionnaire, CBQ) and behavior problem symptom items (Preschool Behavior Questionnaire, PBQ) for their fit to both constructs. With this approach, 10% of temperament and 38% of symptom items were confounded. Second, an empirical approach was taken and CBQ and PBQ items were factor analyzed with data from a multi-informant longitudinal study of 451 children. Using this method, 9% of temperament and 23% of symptom items were confounded. Most importantly, removing the confounded items from the CBQ and PBQ scales did not affect the relation between temperament and symptoms, suggesting that the associations were not due to measurement confounding. In addition, the predictive power of earlier temperament for DSM-IV symptoms (Health and Behavior Questionnaire) remained high with the purified CBQ scale. The findings of this study contribute to the understanding of the relation between normal-range temperament and extreme behavior.     

数学教学中，学生“自主性学习”的培养

所谓“自主性学习”是指学生在明确学习任务的基础上,自觉、自主地进行学习,并努力使自己完成学习任务的一种学习方式。     

Family risk of dyslexia is continuous: individual differences in the precursors of reading skill

The development of 56 children at family risk of dyslexia was followed from the age of 3 years, 9 months to 8 years. In the high-risk group, 66% had reading disabilities at age 8 years compared with 13% in a control group from similar, middle-class backgrounds. However, the family risk of dyslexia was continuous, and high-risk children who did not fulfil criteria for reading impairment at 8 years performed as poorly at age 6 as did high-risk impaired children on tests of grapheme-phoneme knowledge. The findings are interpreted within an interactive model of reading development in which problems in establishing a phonological pathway in dyslexic families may be compensated early by children who have strong language skills.     

对数的一个性质及其运用

对数里有下面这祥一个性质: “若对数式log_ab=c恒成立,一般地有log_(a~n)~(b~n)=c,这里的n∈R,且n≠0”。 [证明] log_ab=c(?)b=a~c■b~n=(a~n)~c 在n≠0时,两边同取以a~n为底的对数, 则有: log_(a~n)~(b~n)=c,n∈R且n≠0 运用上述性质,可解决一些较为复架的对数问题,现举几例如下。 [例1] 已知log_8(x~2+1)~3-log_2xy+log_(2~(1/2))·(y~2+4)/~(1/2)=3 试确定x,y之值 (85年常州初中数学竞赛题) 分析:初中数学竞赛一般不要求换底公式,上述问题即使用换底公式,也颇费周折,若联想到上述性质,则解法较为简捷。     

谈谈政治素质的内容与培养

21世纪是中国社会主义现代化建设的高速发展的时间,到本世纪中叶,我国将最终建成富强、民主、文明的社会主义现代化强国。在这“三位一体”的中国特色社会主义现代化建设目标中,高度民主是不可忽略的重要部分。然而,现代民主政治的发展必须伴随公民政治素质的提高,必要的公民政治素质是现代民主政治赖以实现的基础。政治教育作为素质教育的重要组成部分,势必要在其中扮演重要角色,发挥其应有的作用。
