番鸭花肝病病原的研究

从广西患花肝病的雏番鸭肝、脾分离到 3株病毒 ,定名为NM1、NM2 、NM3。这 3株病毒能在番鸭胚和番鸭胚成纤维细胞上增殖 ,并产生细胞病变。人工感染 1日龄番鸭致死率达 10 0 % ,但对鸡、康贝尔鸭和鹅不致病。分离毒对氯仿不敏感 ,耐热、耐酸 ,不被DNA抑制物所抑制。分离毒的细胞培养物经超薄切片 ,磷钨酸负染 ,在电镜下观察到大量球形、实心 (少量空心 )的病毒粒子 ,其直径 6 6～ 70nm ,无囊膜 ,属无囊膜的RNA病毒     

二战后英国国有化运动述评

二战后,英国工党政府先后掀起两次国有化高潮。战后国有化运动是英国工党“社会主义试验”的重要组成部分,是英国二战后形成的“共识政治”的产物。国有化加重了“英国病”,造成经济停滞、通货膨胀和工业关系的紧张。1979年5月上台的撒切尔政府,为了改变这种局面,试图摒弃凯恩斯主义,从而开始了举世瞩目的“撒切尔革命”。     

小鼠皮肤切创愈合过程中caspase-3的表达及其活性

目的探讨皮肤切创愈合过程caspase-3的表达、激活情况及其活性的变化规律。方法建立小鼠皮肤切创模型后,应用比色法、Western blotting技术对小鼠皮肤切创愈合过程中不同时间段caspase-3的表达、激活情况及其活性进行研究。结果伤后不同时间的caspase-3活性倍增值、caspase-3酶原表达呈现时间规律性变化,并可见caspase-3的激活片段。结论caspase-3可能在皮肤损伤愈合过程中细胞的凋亡中发挥作用,caspase-3可以成为用于皮肤损伤时间推断的指标。     

私人侦探及其调查行为的合法性

我国现阶段存在的所谓的私人侦探及其调查行为不具有合法性。针对目前中国社会中出现的公民私人信息调查的需要,现阶段比较稳妥的做法是不断完善公力救济、适度私力救济。公民群体在追求自身权益保障的同时,要切实树立法律至上的观念,严格遵守相关的法律规定,培养法律意识,促动法治的健康发展,使中国的法治由理想变为现实。     

动物源性金黄色葡萄球菌耐药性的检测

用K B法对52株动物源性金黄色葡萄球菌进行了 17 种抗生素耐药性检测。结果,试验菌对16种抗生素的耐药率达 19.2%~84.6%,耐药率最高的为氨苄青霉素,最低的为头孢曲松;其中对12种抗生素的耐药率在50.0%以上;在52株金黄色葡萄球菌中最少的耐 2 种抗生素,最多的耐15种抗生素,表明临床分离的金黄色葡萄球菌株均表现高水平耐药和多重耐药;受试菌均对万古霉素敏感。     

行政处罚罚款设定普遍化研究

因财产罚所具有的优点、地方立法权的限制以及非正当考虑等因素的影响,罚款设定在日益普遍化的同时,泛化、随意化的趋势也不容否认。事实上,罚款的功能是有限的。面对罚款设定普遍化的现象,必须强调立法目的正当化,并协调配置各种性质的法律责任,以对之进行必要的、合理的矫正。     

论地方保护行为的法律责任之设定

克服地方保护行为的首要任务之一就是设计出一套法律责任体系,从而抵消地方保护行为。这一法律体系中包含的法律责任有撤销、变更、补偿、赔偿以及行政处分、行政处罚、刑罚等。

Work,fertility, and the status of women in Mexico

Among the major transformations affecting Mexican women in recent decades were their growing participation in the labor market and the fertility decline that began in the 1970s with widespread access to contraception. Data from 3 major Mexican fertility surveys, employment surveys, and censuses are used to analyze changes in female employment and their determinants during the years of economic recession in the 1980s. The main characteristics of the Mexican fertility decline are described, and the relationship between fertility and female employment before and during the economic recession is scrutinized for different social sectors. Suggestions for research on the affects of these changes on the social condition of Mexican women are then presented. The proportions of Mexican women over 12 years old who declared themselves economically active increased from 16% in 1970 to 21% in 1979 and 32% in 1987. Until the 1970s the majority of employed women were young and single or childless. But a clear increase occurred between 1976-87 in the economic participation of older women in union. Economic participation of low income and less educated women increased as they sought work or created their own in response to deteriorating living conditions during the recession. Young women with intermediate or higher educational levels did not increase their relative presence in the labor market in the same period. The marked increase in economic participation of less educated women in union with small children was accompanied by a significant increase in manual occupations. Between 1982-87, the proportion of women aged 20-49 in nonsalaried manual occupations rose from 7.6% to 18.5%. Mexico's fertility decline has been well documented. The total fertility rate declined from 6.3 in 1973 to 3.8 in 1986, while the percentage of women in union using a contraceptive method increased from 30.2 in 1976 to 52.7 in 1987. Fertility differentials have been declining but are still considerable. The inhibitory influence of children on female labor force participation in Mexico is clear, but in the years of economic recession the most notable increase in female workers was in women with 3 or more children of whom the youngest was under 3. It appears that the influence of children on women's employment depends on the socioeconomic status of the woman as well as on the dynamism or sluggishness of the labor market. Research is needed on the significance of changes in fertility and female employment for women's status in Mexico. Several recent works have presented results of microsocial analyses of the ways in which women experience changes in their lives resulting from fertility and employment decisions. A methodological strategy for studying these changes and their influence on women's status should focus on comparisons between different generations and birth cohorts, different types of employment, and different socioeconomic statuses. Both macrosocial and microsocial forms of analysis are needed to provide a full picture.
