Beyond tele-substitution: disaggregate longitudinal structural equations modeling of communication impacts

Structural equations and beyond

Disaggregate Transportation Modeling

Geographic information systems (GIS) have developed in response to a range of needs, and provide highly structured environments for working with particular classes of information. The environment and structure of a GIS is defined by its data model; the paper reviews the basic data models of GIS. The needs of discrete transportation modeling have led to a number of extensions of the basic data m...

Nursing Workloads and Psychological Empowerment in Hospitals: Structural Equations Modeling

Background: The high workload of nurses in hospitals has been identified as a patient safety and worker stress problem. Psychological empowerment is a motivational concept demonstrated in four dimensions: meaning, competence, self-determination, and impact. Objective: This study investigated the relationship between nurses’ workloads and psychological emp...

Longitudinal data analysis with structural equations

In this paper we review different structural equation models for the analysis of longitudinal data: (a) univariate models of observable variables, (b) multivariate models of observable variables, (c) models with latent variables, (d) models that are unconditioned or conditioned to other variables (depending on the variability of the independent variables: time-varying or time-invariant, and dep...

Computational Process Modeling of Disaggregate Travel Behavior

In this paper we review attempts to develop CPM of individual travel behavior. CPM represent a linked set of computer programs together with appropriate databases which are designed to capture the essence of human decision making in different spatial situations. Used primarily for wayfmding and to simulate and predict travel behavior, CPMs bypass the difficult problems of IIA typically attribut...
