Constructions of Continuity after Stroke

Prior research suggests that illness disrupts biographical self because of the resulting difficulty in continuing to draw on the same material and symbolic resources used in self‐construction. Recent literature suggests that constructing continuity is possible because of the multi‐faceted nature of self‐construction. One hundred and twenty‐two veterans who had been hospitalized after an acute stroke and discharged home were enrolled in the study. In‐depth interviews were collected from the veterans at one month post‐stroke. Results indicate that some of these individuals construct continuity through their use of personally accessible discursive resources such as expectations for aging and religious beliefs.     

Krylov Sequences as a Tool for Analysing Iterated Regression Algorithms

Abstract.  We use Krylov sequences to analyse a class of regression methods based on successive identification of latent factors. Some results already proved for partial least squares regression (PLSR) are shown to hold for other methods also. We prove that the well-known peculiar pattern of alternating shrinkage and inflation of the principal components is not unique for PLSR. We also show that for any method in the class under study, the coefficient of determination is always at least as high as for principal components regression with the same number of factors.     

长北气田山2段小层砂体三维建模

鄂尔多斯盆地长北气田山西组2段为一套海相辫状河三角洲沉积体系，为揭示不同时期小层砂体发育规模及空间分布，以高分辨率层序地层分析为基础，相控建模为指导思想，短期基准面旋回为地层单元，等时地层格架为约束条件，采用序贯指示数学方法对长北气田山2段4个短期层序的水上分流河道、水下分流河道及河口坝微相小层砂体的发育规模及空间分布进行了随机模拟。砂体展布的三维模拟结果表明，河道自北向南沿物源方向延展，其中SSC1~SSC4短期基准面上升时期，河道加宽，小层砂体沉积厚度加大，物性较好，有利储层发育；下降时期河道变窄，小层砂体沉积厚度减小，物性变差。小层砂体的三维模拟结果在该区勘探实践中得到了很好的验证。

论唐君毅人文思想的中西会通特点

唐君毅的人文思想是儒家传统思想的现代开发。他借助西方哲学资源重新阐发了人的生命存在、人伦关系、人格世界等人文问题,提出了摄末归本的人文主张,并以此为依据对人文群科重新做了排序。唐君毅的人文思想是以儒家思想为主兼容西学的"返本开新",这种"返本开新"为深入了解中西文化融会的路径提供了可资借鉴的经验。     

从“差序格局”到“中华民族多元一体格局”的跨越

差序格局与中华民族多元一体格局是费孝通先生提出的解释中国社会结构的两把"金钥匙",前者侧重微观层面,而后者侧重宏观层面。该文力图探究如何实现从微观层面的差序格局到宏观层面的中华民族多元一体格局的跨越,即发现宏观理论的微观基础与微观理论的宏观推论。笔者运用"同心球"模型,重点研究了"民族"在差序格局中的重要作用,以此实现两个理论之间的跨越:在"己-家-民族-国-天下"体系中把握"群体"的特点和意义,在动态当中把握差序格局与中华民族多元一体格局的联系。     

汉字笔顺存疑——“丑、贯、再、里、单、讯”的笔顺问题讨论

“丑、贯、再、里、单、讯”等汉字都有横竖交叉笔画,调查结果显示,人们书写这几个汉字横竖交叉笔画的习惯笔顺是“先横后竖”.1997年国家颁布的《现代汉语通用字笔顺规范》与这一习惯笔顺相符合的只有“单、讯”两字,《现代汉语通用字笔顺规范》中“丑、贯、再、里”的横竖交叉笔画的笔顺是“先竖后横”,与人们习惯不一致.笔顺规范应该尊重大多数人的书写习惯,需要把“丑、贯、再、里”四个字的横竖交叉笔画的笔顺规范改成“先横后竖”,让规范符合绝大多数人的习惯.     

Subjective health and its relationship with working time variables and job stressors: Sequence or general factor model?

Abstract

This study compares two theoretical models that make different assumptions about the structure of subjective health constructs and about the effects of job stressors and working time variables on health. The first model, the sequence model, is based on sequential models of the development of ill-health and posits that chronic fatigue and sleep problems mediate the effects of job stressors and working time variables on depression and somatic complaints. The second model, the general strain factor model, posits that specific health constructs (e.g. fatigue, depression, and somatic complaints) are reflections of a common general strain factor (i.e. detrimental job conditions increase the individual's sensitization to strain). In this way the study expands traditional models of stress-related effects on health. The analyses were carried out in a sample of 365 individuals in Germany. Although both models fitted the data, the general strain factor model was found to be superior. Furthermore, the effects of job stressors and working time on the health constructs fatigue and sleep quality were mediated by the general strain factor. Also, a negative relationship emerged between working time duration and general strain. It is suggested that the general strain model could be useful in future health psychology research.     

试解达尔文学说的五点争议

与生物的高级低级及其进化的必然性等问题的争论至今仍然没有定论。我们可以给高级和低级赋予客观的含义，即用复杂程度和有序程度作为评价物质系统高级和低级的标准。序参量应该是系统功能的总价值，只有当系统结构的变化导致新功能出现时，才会使有序度增大。生物进化具有必然性，因为高级生物可以利用上层资源。如果认为进化是一个先验的方向就错了，但是可以在演化结果出现以后把进化当成主流。对于进化有必要单独研究，不能在任何情况下都用演化代替进化。
