objective: in order to find how rating the whoqol-bref and dass scales are combined to produce an overall measure of quality of life and satisfaction with health rating, a qol-dass model was designed; and the strength of this hypothesized model was examined using the structural equation modeling. method: participants included a sample of 103 voluntary males who were divided into two groups of u...

A two-state life history model governed by ODEs is formulated to elucidate the population dynamics of jellyfish and to illuminate the triggering mechanism of its blooms. The polyp-medusa model admits trichotomous global dynamic scenarios: extinction, polyps survival only, and both survival. The population dynamics sensitively depend on several biotic and abiotic limiting factors such as substra...

It is suggested that life originated in a three-step process referred to as the jigsaw model. RNA, proteins, or similar organic molecules polymerized in a dehydrated carbon-rich environment, on surfaces in a carbonrich environment, or in another environment where polymerization occurs. These polymers subsequently entered an aqueous environment where they folded into compact structures. It is ar...

Although intensive work has been devoted to Spatio-temporal (ST) qualitative reasoning models, some issues such as management of complex objects life and motion remain. First, ST histories’ clustering using a set of life and motion configurations is briefly presented. Then, we discuss a model based on the generalization of the life and motion configurations into a set of 25 relationships. These...

To lay the foundation for our model, we first describe existing conceptions of successful aging, underlying assumptions of development, and criteria for success. The model presented extends the discourse on this topic in three directions: (a) It frames the discussion of successful aging in the broader context of life course development; (b) it accounts for both normative and nonnormative (i.e.,...

MOTIVATION Business Architecture Models (BAMs) describe what a business does, who performs the activities, where and when activities are performed, how activities are accomplished and which data are present. The purpose of a BAM is to provide a common resource for understanding business functions and requirements and to guide software development. The cancer Biomedical Informatics Grid (caBIG®)...
