A prospective analysis of work in schizophrenia.

This study examined the longitudinal course of competitive employment in patients with schizophrenia following treatment for an acute exacerbation, and prospectively predicts work approximately 2 years later from sociodemographic and clinical characteristics. A sample of 528 patients was assessed at baseline, and 313 were followed up 1 and 2 years later. Assessments included sociodemographic characteristics, premorbid functioning, work history, symptoms, social functioning, recent efforts to find work, and interest in work. Analyses examined changes in competitive work from baseline to the followups, the correlates of work history, the prospective prediction of work at the 1- and 2-year followup assessments, and correlates of competitive work. Competitive employment increased significantly from 10 percent at baseline to 23 percent and 21 percent at the 1- and 2-year followups, respectively. At baseline, among patients who were not competitively working, 61 percent reported interest in working. Patients who were not competitively employed at baseline but reported making recent efforts to find work were more likely to be working at the followups than other not employed patients. Work at the 1- and 2-year followups was predicted by prior work experience, patient and mother's educational level, cognitive impairment, and social functioning. Similar correlates of current work status were found. Interventions may need to target educational level, cognitive impairment, and social competence and functioning in order to improve the competitive employment outcomes of persons with schizophrenia.

A generalized signal detection model to predict rational variation in base rate use.

The predominant models of rational behavior currently used to analyze a large class of experiments imply that subjects neglect or place insufficient weight on base rates when making probabilistic judgments. We argue that the evidence is inadequate for this conclusion because the models make needlessly restrictive assumptions about how base rates should be used. The restrictive assumptions stem from a misuse of Bayes' rule that ignores specific aspects of how the proportions arose. We develop a model of rational behavior that generalizes signal detection theory to reflect the environment subjects routinely face and we reexamine the relevant experimental literature. Variation observed in subjects' responses to base rate information is explained by the present rational model more fully than by extant models.

The role of equilibrium and disequilibrium in modeling regional growth and decline: a critical reassessment.

The authors critically examine a 1990 study by Alan W. Evans concerning the assumption of interregional equilibrium in recent migration research. "We here argue that Evans is unconvincing in his primary substantive argument; we provide an alternative reading of the literature that supports this assertion....[We then illustrate] the substantive issues in terms of a simple formal model that allows for both equilibrium and disequilibrium migration." The geographical focus is on the United States. A reply by Evans is included (pp. 89-97).

New directions in migration research: perspectives from some North American regional science disciplines.

"This paper takes several surveys of the literature concerning migration research as its starting point and directs the reader toward a number of potentially fruitful lines for future research. Major sections include one on modeling migrant choice in which the pros and cons of using gross versus net migration measures are discussed. A second introduces and discusses the concept of a 'spatial' choice set, which has the potential to be implemented with laboratory experimental techniques. The third involves a wide-ranging discussion of new directions in modeling the interrelationships between employment and migration." The primary geographical focus is on the United States.

Measuring the impact of locational characteristics on migration: interpreting cross-sectional analyses.

Methods that employ cross-sectional data to analyze the impact of locational characteristics on migration decisions may produce seriously biased results because migrant decisions at any one point in time reflect historical as well as contemporaneous forces. A comparison of results based on a typical cross-sectional analysis and those obtained with longitudinal data shows that these issues are of empirical importance. An alternative interpretation of the results of cross-sectional migration analyses is provided.

Implications of boundary choice for the measurement of residential mobility.

Analyses of residential mobility are usually conditioned on a system of geography in which territory is divided into discrete units. Types of movement are defined in terms of these units, the most important distinction being that between local mobility and migration. Here we examine explicitly the implications of the choice of the migration-defining boundary in the U.S. over the 1940-1980 period. We demonstrate how boundary choice influences the extent and character of selectivity of the mobile population by using demographic and social characteristics. It appears that over time the state line may be replacing the county line in distinguishing kinds of migrants. Further, our results point to a growing fraction of footloose migrants, not tied to local territory, identified by their migration history rather than demographic characteristics.
