Understanding patient factors related to physical activity behavior is important in the management of Type 2 Diabetes. This study applied the Theory of Planned Behavior model to understand physical activity behavior among sampled Type 2 diabetics in Kenya. The study was conducted within the diabetic clinic at Kisii Level 5 Hospital and adopted sequential mixed methods design beginning with qual...

background: there can be little doubt that the construction is the most hazardous industry in the worldwide. this study was designed to modeling the factors affecting unsafe behavior from the perspective of safety supervisors. methods: the qualitative research was conducted to extract a conceptual model. a structural model was then developed based on a questionnaire survey (n=266) by two stage ...

In this paper the qualitative dynamic behavior of reaction kinetic models of G protein signaling is examined. A simplified basic G protein signaling structure is defined, which is extended to be able to take the effect of slow transmission, RGS mediated feedback regulation and ERK-phosphatase mediated feedback regulation into account. The resulting model gives rise to an acceptable qualitative ...

We define several qualitative classes of cellular automata (CA) behavior, based on various statistical measures, and describe how the space of all cellular automata is organized. As a cellular automaton is changed by varying entries in its rule table, abrupt changes in qualitative behavior may occur. These abrupt changes have the character of bifurcations in smooth dynamical systems, or of phas...

Most of the work on behavior prediction on the field of Qualitative Physics has focused on transient behavior and responses to perturbations (de Kleer Brown 1984; Forbus 1984; Kuipers 1985; Williams 1984); very little has been done about behavior of systems in steady state (Sussman & Steele 1980). understanding of the sinusoidal steady state of electrical circuits is important for several reaso...

In this study, Science Applications International Corporation (SAIC) and Georgia Institute of Technology (GT) developed a quantitative-qualitative mixed methods research technique to investigate the extent to which real world characteristics of Massively Multiplayer Online Role-Playing Game (MMORPG) players can be predicted based on the characteristics and behavior of their avatars. SAIC used t...

Although modern control theories have been successfully applied to solve a variety of problems, they are often mathematically and physically too specific to describe and analyze the qualitative properties of hybrid real-time systems. In this paper, we propose the use of qualitative formal methods, Compositional Modeling Language (CML) and Causal Functional Representation Language (CFRL) in part...

This paper presents a theory of corn monsense understanding of the behavior of electronic circuits. It is based on the intuitive qualitative reasoning electrical engineers use when they analyze circuits. This intuitive reasoning provides a great deal of important information about the operation of the circuit, which although qualitative in nature, describes important quantitative aspects of cir...

This course is devoted to the study of systems of ordinary differential equations (ODEs), in terms of analytical and numerical solution techniques, and also acquiring insight into the qualitative behavior of solutions. We begin our study of a general system of n ODEs of the form y′ = F(t,y), where y(t) : R→ Rn and F : Rn+1 → Rn, with some examples that illustrate very different types of qualita...
