猪瘟与蓝耳病混合感染的诊断与治疗方法

通过流行病学调查、临床表现、病理剖检对新乡市长垣县赵堤镇某猪场发生的一起以体温升高、不食、腹泻、耳部发绀、鼻部、腹下、臀部、四肢末端发紫为特征的疾病,做出初步诊断为猪瘟与蓝耳病混合感染,然后采取10份病料经处理后用正向间接血凝试验检测CSF,酶联免疫吸附试验检测PRRS,结果表明CSF的阳性率为80%,PRRS的阳性率为60%,从而确诊该病为CSF与PRRS混合感染,通过采取自家苗、抗猪瘟血清、接种疫苗三种方法作比较,同时肌肉注射杂症一针,菌毒急救,拌料饲喂防蓝灵,金方案Ⅱ型,饮水中添加口服补液盐,电解多维等综合防治措施,结果显示自家苗治疗效果最好,病情得到控制,治愈率达70%,为目前规模化猪场混合感染的快速检测和治疗提供了可参考性的建议.     

伊本·路西德的认识论和社会伦理观

伊本·路西德是阿拉伯中世纪最伟大的哲学家,他认为真理具有可知性,人的认识是从个别到一般,从感性到理性;他继承先哲,完整系统地论述了双重真理论,力图在调和哲学和宗教的同时,提升哲学的地位,强调理性的作用;他的理想社会理论虽然带有若干空想的成分,但有些思想在今天仍有其理论意义和现实价值。

Generating functions for powers of second-order recurrence sequences

For the sequences satisfying the recurrence relation of the second order,the generating functions for the products of the powers of these sequences are established.This study was from Carlita and Riordan who began a study on closed form of generating functions for powers of second-order recurrence sequences.This investigation was completed by Stnica.Inspired by the recent work of Istva'n about the non-closed generating functions of the products of the powers of the second-order sequences,the authors give s...     

教育网站评价的网络计量模式初探

目前,教育网站评价中普遍存在主观多客观少、静态多动态少的问题,因此,引入新的评价模式增强教育网站评价的动态性和客观性成为必然的选择.Alexa排名在网站评价中的广泛应用,使得教育网站评价的网络计量模式开始走进实践和理论研究的视野.本文从网络计量模式的内涵、各种网络计量指标及其评价意义、网络计量模式的实施方法等三个方面详细阐述了网络计量模式在教育网站评价中的应用框架,文章最后还讨论了实施教育网站网络计量评价可能遇到的问题以及后续研究工作.

Interactive Effects Between Maternal Parenting and Negative Emotionality on Social Functioning Among Very Young Chinese Children

Research Findings: This study examined how child negative emotionality interacted with mothers’ self-reported parenting in predicting different aspects of social functioning among very young Chinese children. A total of 109 Chinese nursery children in Hong Kong participated with their parents. Maternal supportive and aversive parenting practices were reported by mothers, and child negative emotionality and social functioning were reported by both mothers and fathers. The results revealed interaction effects between child negative emotionality and mothers’ self-reported parenting on children’s internalizing problems, externalizing problems, and social-emotional skill deficiency. Specifically, children with high negative emotionality were more susceptible to the negative effects of aversive parenting (i.e., showing more internalizing and externalizing problems when exposed to aversive parenting) than their peers with low negative emotionality. Negative emotionality also placed young children at risk for social-emotional skill deficiency, especially when they received less support from their mothers compared to their peers. Practice or Policy: Special attention should be paid to the social functioning of Chinese children with higher levels of negative emotionality, because these children are more vulnerable to poor-quality parenting at a very young age.
