Epidemiology characterizes the influence of causes to disease and health conditions of defined populations. Cohort studies are population-based studies involving usually large numbers of randomly selected individuals and comprising numerous attributes, ranging from self-reported interview data to results from various medical examinations, e.g., blood and urine samples. Since recently, medical i...

This paper presents results from an auditory-visual recognition experiment employing short utterances of German produced with varying attitudinal expressions. It is based on 16 different kinds of social and/or propositional attitudes which place speakers in various social interactions with a partner of inferior, equal or superior status, and having a communication aim with a positive, neutral o...

We study numerical solution of systems of delay-differential equations in which the delay function, which depends on the unknown solution, is defined implicitly by the threshold condition. We study discrete variable numerical methods for these problems and present error analysis. The global error is composed of the error of solving the differential systems, the error from the threshold conditio...

Health-related studies of spirituality are threatened by the lack of conceptual distinctions between religion and spirituality, the use of small, nongeneralizable samples, and by measurement error in many instruments that unreliably and invalidly capture this domain. The authors review the construct and validity evidence for the Spirituality Index of Well-Being (SIWB), an instrument designed to...

In this paper, we have introduced a fractional-ordered predator-prey population model which has been successfully solved with the help of two powerful analytical methods, namely, Homotopy Perturbation Method (HPM) and Variational Iteration Method (VIM). The fractional derivatives are described in the Caputo sense. Using initial values, we have derived the explicit solutions of predator-prey pop...

The Trait Meta-Mood Scale (TMMS; Salovey, Mayer, Goldman, Turvey, & Palfai, 1995) is a well-established measure of perceived emotional intelligence, an aspect of emotional intelligence that includes people’s beliefs and attitudes about their own emotional experience. Although the TMMS has been widely used in adult populations, until now no data have been reported on its validity in the adolesce...
