In all clinical and research work, it is important not only to have uniform diagnostic criteria but also some means of objectively quantifying the presence and severity of the illness being studied. For this purpose, a number of ra t ing scales have been devised for depressive disorders, probably the single most commonly used one being the Hamilton Ra t ing Scale (Hamil ton, 1960). The total sc...

English language practitioners have long relied on intuition-based scales for rating EFL/ESL writing. As these scales lack an empirical basis, the scores they generate tend to be unreliable, which results in invalid interpretations. Given the significance of the genre of description and the fact that the relevant literature does not introduce any data-based analytic scales for rating EFL descri...

A new measure for reliability of a rating scale is introduced, based on the classical definition of reliability, as the ratio of the true score variance and the total variance. Clinical trial data can be employed to estimate the reliability of the scale in use, whenever repeated measurements are taken. The reliability is estimated from the covariance parameters obtained from a linear mixed mode...

Instructors often incorporate selfand peer evaluations when they use teamwork in their classes, which is common in management education. However, the process is often time consuming and frequently does not match well with guidance provided by the literature. We describe the development of a web-based instrument that efficiently collects and analyzes selfand peer-evaluation data. The instrument ...

A statistical training study is reported which demonstrates that analytic responding on everyday reasoning problems can be increased after instruction in statistical principles. Participants were given training on the Law of Large Numbers (Fong, Krantz and Nisbett, 1986). Bias was eliminated, but only on written justifications of their responses. Belief-based responding was still utilized when ...

Introduction Citation-based bibliometric indicators are increasingly being used for evaluating research. This reflects the need of decision-makers to increase the efficiency of allocating resources to research institutions and scientists, while also keeping manageable and cost-effective the evaluation process that grounds the allocation of resources. There often is much room of improvement in h...

Our purpose here is to announce results in harmonic analysis related to a large class of hypoelliptic operators on arbitrary simply-connected nilpotent Lie groups. We find the asymptotic development of their fundamental solutions, both locally and at infinity, and study corresponding Riesz transforms and analogues of the Hardy-Littlewood-Sobolev theorem for fractional integration. Details will ...

The purpose of this research is to develop a morphologically determined scale—the Tomography Dementia Rating scale (TDR) to diagnose AD stages, based on the measurement of the severity of voluminal atrophic changes of the temporal lobes of the brain detected among patients during CT and MRI at various stages of the disease. The research included 140 patients aged 28 79. Test Group comprised 81 ...
