In this paper, we investigate the complete moment convergence and Lr convergence for maximal partial sums of asymptotically almost negatively associated random variables under some general conditions. The results obtained in the paper generalize some corresponding ones for negatively associated random variables. 相似文献

Child‐caregiver Attachment Representations in a Non‐Western Context: The Feasibility and Cultural Equivalence of Story Stems in Urban Ghana 下载免费PDF全文
Story stem measures are an increasingly popular method for assessing the attachment representations of young children, but little is known of their cross‐cultural applicability. This study aimed to characterise the attachment representations in 73 five‐ to eight‐year‐old children in urban Ghana, West Africa, using the Manchester Child Attachment Story Task (MCAST) to test its feasibility, psychometric characteristics and concurrent associations with caregiver‐ and teacher‐rated child behaviour, and to conduct a qualitative thematic analysis of methodological observations. Among the classifiable cases (92 percent), all attachment classifications were observed, yielding a higher rate of secure attachment than in European samples. Inter‐rater reliability, internal consistency, and internal structure were reasonable and largely similar to European studies, although one structural difference was the separation of ‘child assuagement of distress’ from other secure‐related items. MCAST narratives were associated with teacher‐ and caregiver‐rated hyperactivity, but internal consistency was low in most Strengths and Difficulties Questionnaire scales. Possible culturally‐sensitive explanations for our psychometric and qualitative findings are discussed. Overall, story stems are a promising tool for accessing attachment representations in non‐Western samples, although modifications are likely to improve cross‐cultural equivalence when applied to non‐Western cultures. Further investigation is needed to link MCAST outcomes to parenting and socio‐emotional development. 相似文献

Several colorectal cancer (CRC) screening models have been developed describing the progression of adenomas to CRC. Currently, there is increasing evidence that serrated lesions can also develop into CRC. It is not clear whether screening tests have the same test characteristics for serrated lesions as for adenomas, but lower sensitivities have been suggested. Models that ignore this type of colorectal lesions may provide overly optimistic predictions of the screen‐induced reduction in CRC incidence. To address this issue, we have developed the Adenoma and Serrated pathway to Colorectal CAncer (ASCCA) model that includes the adenoma‐carcinoma pathway and the serrated pathway to CRC as well as characteristics of colorectal lesions. The model structure and the calibration procedure are described in detail. Calibration resulted in 19 parameter sets for the adenoma‐carcinoma pathway and 13 for the serrated pathway that match the age‐ and sex‐specific adenoma and serrated lesion prevalence in the COlonoscopy versus COlonography Screening (COCOS) trial, Dutch CRC incidence and mortality rates, and a number of other intermediate outcomes concerning characteristics of colorectal lesions. As an example, we simulated outcomes for a biennial fecal immunochemical test screening program and a hypothetical one‐time colonoscopy screening program. Inclusion of the serrated pathway influenced the predicted effectiveness of screening when serrated lesions are associated with lower screening test sensitivity or when they are not removed. To our knowledge, this is the first model that explicitly includes the serrated pathway and characteristics of colorectal lesions. It is suitable for the evaluation of the (cost)effectiveness of potential screening strategies for CRC. 相似文献

“大众化”思潮在中国近现代文学中是个一以贯之的潮流,虽然左翼文学界的文艺大众化是从批判“五四”文学开始的,但作为大众化运动的领导者与实践者之一的周文在文学的根本问题与原则问题上,都继承了“五四”新文学的精神。他提出文学要面向大众,要使用“活”的语言,而且还利用自身在边区政府的领导地位,完成了公文改革,实现了“五四”未竞的事业。 相似文献

所谓伊斯兰文化的研究方法,是指正确地进行伊斯兰文化研究所应遵循的一套原则、手段、程序和技巧。研究方法在伊斯兰文化的发展过程中承担着特别重要的职能,它在一定程度上制约、规范着伊斯兰文化发展的水平和风格。没有成熟、科学的研究方法,就不会产生成熟、发达的伊斯兰文化。就伊斯兰文化的研究方法,我们有两点拙见,把它说出来,以求教学人。 首先,摆正伊斯兰与伊斯兰文化的关系。伊斯兰文化作为一种宗教文化实体,与伊斯兰密不可分,互为依托。按照伊斯兰的基本教义,伊斯兰是安拉的意志,通过《古兰经》和圣训得以具体体现。两者是伊斯兰教的基础和最基本的经典,是伊斯兰国家信仰原则、哲学思想、政治经济、法律创制和司法实践的权威准则和第一源泉。而伊斯兰文化是由阿拉伯民族和穆斯林各民族在社会历史实践中共同参与创造 相似文献
