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...

Structural Equations and Causation

Beyond logistic regression: structural equations modelling for binary variables and its application to investigating unobserved confounders

BACKGROUND Structural equation modelling (SEM) has been increasingly used in medical statistics for solving a system of related regression equations. However, a great obstacle for its wider use has been its difficulty in handling categorical variables within the framework of generalised linear models. METHODS A large data set with a known structure among two related outcomes and three indepen...

Dispersive Equations and Their Role beyond Pde

Arguably the star in the family of dispersive equations is the Schrödinger equation. Among many mathematicians and physicists it is regarded as fundamental, in particular to understand complex phenomena in quantum mechanics. But not many people may know that this equation, when defined on tori for example, has a very reach and more abstract structure that touches several fields of mathematics, ...
