随机过程一阶概率分布函数的遍历性     

刘轩黄 《江西电力职业技术学院学报》2004,17(2):1-3

提出了随机过程一阶概率分布函数具有遍历性的一个充分必要条件(定理1和推论1),并在较弱条件下,对一般的关于随机变量函数分布定理作了进一步的推广(定理2)。利用这些结果,讨论了随机初相位周期过程一阶分布函数的遍历性(推论2)。最后,作为应用,用具有一维均匀分布的随机过程构造了一种白噪音模型。  相似文献   

Social Work Intervention with White Collared Employees and Their Families     

Y.?S.?SiddeGowdaEmail author 《International journal for the advancement of counseling》2004,26(4):421-432

This investigation presents a framework for understanding and also to test the efficacy of Social Work intervention on the well being of the white collared employee (industrial employee) and his/her family. A comprehensive and intensive personal- family exploration was done to uncover the relatedness of seemingly disparate areas of the clients lives. A total of 80 executives (industrial employees) served as subjects. A baseline assessment was done using structured, standardized interview-schedules/questionnaires. The results of the study can be enumerated as follows: After the Social Work intervention, the executives in occupational profile, there were significant changes in Role perception, overload, role conflict, low status and poor peer relations. In coping strategies there was significant improvement in sub-scales like problem solving and unproductive coping. Significant reduction was noticed in their proneness to heart disease, depression, inadequate mental mastery, and perceived ill health. There was significant improvement in their family group support, and in their expressiveness, achievement, orientation, active-recreational and organizational characteristics.  相似文献

对虾白斑综合症病毒囊膜蛋白Vp28基因的克隆、表达及蛋白纯化     

吴小婷  陈曦  陈宇  刘斌  吴文林 《泉州师范学院学报》2011,29(4):41-44

以对虾白斑病毒DNA为模板扩增出Vp28基因,经限制性内切酶（SmaI,Not I）酶切后按正确的读码框顺序插入到pGEX-4T-2表达载体上,重组质粒转化大肠杆菌,经菌落PCR和质粒双酶切鉴定、序列测定确认,证实成功地构建了Vp28基因原核表达载体．转化菌经IPTG诱导表达,SDS-PAGE显示有与预期大小约52kD相吻合的融合蛋白带,18℃诱导24h后获得了可溶性表达的目的蛋白,采用Glutathione Sepharose 4B亲和层析对重组蛋白进行纯化,获得了纯度很高的目的蛋白．  相似文献

The one-in-ten: quantitative Critical Race Theory and the education of the ‘new (white) oppressed’     

Claire E. Crawford 《教育政策杂志》2019,34(3):423-444

ABSTRACT

This paper challenges the notion that quantitative data – as a numeric truth – exist independent of a nation’s political and racial landscape. Utilising large-scale national attainment data, the analysis challenges the belief that ‘White working class’ children in England, especially boys, are ‘the new oppressed’ – as a former equality adviser has publicly claimed. The analysis applies Quantitative Critical Race Theory, or ‘QuantCrit’, an emerging quantitative sub-field of Critical Race Theory in education. The paper argues that far from being ‘oppressed’, White boys continue to enjoy achievement advantages over numerous minoritised groups; especially their peers of Black Caribbean ethnic origin. Additionally, the analysis uniquely exposes racialised trends of ‘equivalency’ in core subject qualifications, whereby minority ethnic children are over-represented in certain lower-status qualifications that are counted as equivalent in education statistics but not in the real world labour market. The analysis concludes that knowing misrepresentations of quantitative data are at the heart of an institutional process through which race and racism are produced, legitimised and perpetuated in education.  相似文献
