Constituency Opinion: A Test of the Surrogate Model

Using direct measures of district opinion, this article teststhe linearity and additivity assumptions of the surrogate model.Neither assumption is upheld when subjected to appropriate empiricaltests     

Political competence and ideological constraint

Converse's definition of ideological contraint is expanded to provide for various respondent identified ideological dimensions rather than an all encompassing liberal-conservative dimension. Using this redefinition a sample of adults is shown to have high levels of ideological constraint. Ideological constraint is shown to vary with the degree of cognitive complexity and the degree of preference evaluability. The latter is a new concept that suggests that some issues will be easier for a respondent to demonstrate constraint on depending upon the availability and applicability of preference criteria. Salience is also shown to have a positive relationship with ideological constraint, but only when preference evaluability is high.     

Evaluating a Group Home: Problems and Results

Summary The need for an evaluative framework for group homes for thementally ill is discussed. Evaluation involves separating implicitfrom explicit objectives. The possible objectives for a grouphome are considered in terms of the questions of who decideswhat the objectives are to be, how they are defined, and theirrelationship to the idea of normality. A further issue in decidingobjectives is whether the client's independence is to be foundwithin the group home or beyond it. The elements of a group home's regime are then considered: theseinclude control and group support. Problems in measuring theelements involved are mentioned. An evaluative scheme based upon this is then drawn up for aparticular group home, and the results described. The residentsare found to have experienced little change overall in theirlevel of independence, and this is associated with a regimewhere residents act in a dependent way towards staff, and staffperceptions of control and support are different from thoseof residents.     

A graph-theoretical approach to the aggregation of individual preference orderings

A graph-theoretical approach as first outlined by Harary et al. is developed for solving the problem of aggregating a given set of individual preference orderings provided that no individual preferential judgment is inconsistent with the collective preference ordering obtained by aggregation.
