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.     

A SOCIOLOGY FOR OUR TIMES: Alvin Gouldner's Message

For the St. Louis meeting of the Midwest Sociological Society, the author organized a special session to reflect on the particular sociological tradition associated with Washington University, with a particular focus on Alvin Gouldner's work. From that session came this symposium, for which various papers presented were developed into articles. The session and these articles raise important issues for what they tell us both about Gouldner's work and about where sociology is as a discipline today. Among these issues are (1) the optimistic quest for objective value-free knowledge positivism entailed in the past versus a self-reflexive quest for knowledge that entails a tragic acceptance of its limits at present, (2) the effort to distinguish social theory from sociology, ideology, and politics, with all of whom it overlaps as they strive to be both social diagnosis and social therapy, (3) the production of knowledge as dependent both on the lived experiences that shape our biographies and on the intellectual influences available in the local settings where we work, (4) the effort to warn us against the various excesses to which our disciplinary and personal commitments give way, and (5) the role social theory can play as a search light that illuminates our way in the darkness of the empirical world in which we live, while it simultaneously casts a shadow.     

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'.
