A MATLAB toolbox has been developed to handle the basic problems of discrete event dynamical systems that are modeled by Petri nets. In the Petri Net Toolbox five types of Petri nets (untimed, transition-timed, place-timed, stochastic and generalized stochastic), with finite or infinite capacity, can be used. A user-friendly graphical interface allows activating three simulation modes (accompan...

Non-fatal injuries have a significant impact on disability, productivity, and economic cost, and first-aid can play an important role in improving non-fatal injury outcomes. Data collected from a census conducted as part of a drowning prevention project in Bangladesh was used to quantify the impact of first-aid provided by trained and untrained providers on non-fatal injuries. The census covere...

Recent research has shown how to incorporate time in probabilistic modeling techniques called influence nets that are used to model complex political/military situations. By adding timing information to these models, which are static equilibrium models, they are converted to discrete event system models that can be represented as colored Petri nets. Executing these CP nets reveals the dynamic c...

OBJECTIVES To investigate the challenges of providing oral health advice/treatment as experienced by non-dental primary care providers in rural and remote areas with no resident dentist, and their views on ways in which oral health and oral health services could be improved for their communities. DESIGN Qualitative study with semistructured interviews and thematic analysis. SETTING Four rem...

BACKGROUND The private medical care sector is expanding in urban cities in Sub-Saharan Africa (SSA). However, people's health-care-seeking behaviors in this new landscape remain poorly understood; furthermore, distinguishing between public and private providers and among various types of private providers is critical in this investigation. This study assessed, by type, the healthcare providers ...

INTRODUCTION Gender disparities in income continue to exist, and many studies have quantified the gap between male and female workers. These studies paint an incomplete picture of gender income disparity because of their reliance on notoriously inaccurate or incomplete surveys. We quantified gender reimbursement disparity between female and male healthcare providers using objective, non-self-re...

PURPOSE The study evaluates how providers give patient education materials and identifies improvements to comply with Meaningful Use (MU) requirements. METHODS Thirty-eight patient-provider interactions in two health care outpatient clinics were observed. RESULTS Providers do not uniformly know MU patient education requirements. Providers have individual preferences and find gaps in what is...
