The identification of logistic regression models with errors in the variables

The simple logistic regression model with normal measurement error and normal regressor is shown to be identifiable without any extra information about the measurement error. The multiple logistic regression model with more than one regressor variable measured with error is not identifiable. If the covariance matrix of the measurement error is known up to a scalar factor, the model is identified. Further we discuss why in spite of the identifiability the models cannot be estimated in a reasonable way without extra information about the measurement error.     

On social work and what gender has got to do with it

Living in gendered societies makes it necessary to take into account the specific ways in which social problems and social issues affect the lives of women and men, girls and boys. Not only are social problems and social issues very often gender biased; this is also true for the professions dealing with these problems and issues, and for the training programmes for professions like social work. Sociological analysis of society and philosophical understanding of a good life are permeated by gender-specific perceptions -- often without those involved being aware of them. Furthermore, social policies reinforce gender-specific biases because they are based on gender-specific (i.e. male) standards. Gender as an analytical category has been brought into scientific and public discourse by feminist theoreticians and activists making women -- and thus also men -- visible with regard to structure and subject issues. The development of gender theory and research highlights the significance of gender arrangements to understand social phenomena and to support gender-equality ways of thinking and policies. At the same time, men and women are not only confronted with gendered structures, but via socialization processes and personal development they also reproduce these gender differences in their daily lives by 'doing gender'.

全球化语境与文学的民族性

全球化与文学的民族性 ,从根本上说是一个历史问题在当前新的历史语境下的重新言说。它既表现出作为历史问题的滥觞所提供和积累的经验性意义 ,又由于历史境遇的深刻变化而必然呈示出“新质” ,并由此构成对世界现实秩序的挑战。我们既要坚持以“国家和民族”的范式参与“世界文学”的对话 ,又应积极地把握“全球化”态势以激活民族的文学     

论人生厄运

厄运是相对于幸运而言的，厄运造成痛苦可以划分为三种不同类型。对厄运造成痛苦的根源，应该从人与环境的相互作用出发来探究，由于人所生存的环境不是单一性质的，而是多种因素的复杂系统，所以，要进行系统的具体分析。厄运对人生的作用有二重性，应该正确面对，实现理性升华。
