Modelling method effects as individual causal effects

Summary.  Method effects often occur when different methods are used for measuring the same construct. We present a new approach for modelling this kind of phenomenon, consisting of a definition of method effects and a first model, the method effect model , that can be used for data analysis. This model may be applied to multitrait–multimethod data or to longitudinal data where the same construct is measured with at least two methods at all occasions. In this new approach, the definition of the method effects is based on the theory of individual causal effects by Neyman and Rubin. Method effects are accordingly conceptualized as the individual effects of applying measurement method j instead of k . They are modelled as latent difference scores in structural equation models. A reference method needs to be chosen against which all other methods are compared. The model fit is invariant to the choice of the reference method. The model allows the estimation of the average of the individual method effects, their variance, their correlation with the traits (and other latent variables) and the correlation of different method effects among each other. Furthermore, since the definition of the method effects is in line with the theory of causality, the method effects may (under certain conditions) be interpreted as causal effects of the method. The method effect model is compared with traditional multitrait–multimethod models. An example illustrates the application of the model to longitudinal data analysing the effect of negatively (such as 'feel bad') as compared with positively formulated items (such as 'feel good') measuring mood states.

An Organizational Model of Higher Education Institutions and Faculty Teaching Goals*

The theory of organizations as “open systems” is used to develop hypotheses on the relationship between academic institutions and faculty teaching goals. The effects of three measures of academic organizations–type of control, institutional functions, and institutional affluence–on faculty support for four types of teaching goals are tested with data from a nationally representative sample of 301 academic institutions. Through the use of a path analytic model, it was found that these organizational characteristics directly affect the types of teaching goals faculty members endorse and the level of support for teaching goals in general.     

Special Education Knowledge Seen as a Social Problem

The article is based on a historical study aiming at analysing the historical determinants for the academic content of the special educational discipline-regarding both ideological attitudes against disability and segregation and more concrete initiatives of action-as it appeared when the expert-function of special education was established during the 1920s and 1930s in Sweden. As the determinants I consider the nineteenth, as well as the twentieth cetury's socio-ideological, educational political and educational philosophical discourses. In order to describe the tendencies in contents I have used the first Scandinavian journal in the special educational field (Hjalpskolan). I have in my discussion been inspired by Michel Foucault's analysis of subtle conditions of power, in the forms of regulations and control mechanisms between the societies 'normal' and its marginal groupings. The essence of the study is that these tendencies are socially constructed within the knowledge tradition of the swedish compulsory school system. Despite their variations they can be classified as follows: a moralizing theme, where the various scientifically coloured arguments for and against segregation are discussed. A religious 'merciful' theme; the genuine human loving compassion with 'the societies least fortunate'. Finally, the sociopolitical theme with focus on socio-economical discussion.
