Despite a substantial research literature on the influence of dimensions and exercises in assessment centers (ACs), the relative impact of these two sources of variance continues to raise uncertainties because of confounding. With confounded effects, it is not possible to establish the degree to which any one effect, including those related to exercises and dimensions, influences AC ratings. In...

Variance of time-of-flight distributions have been shown to be more sensitive to cerebral blood flow (CBF) during dynamic-contrast enhanced monitoring of neurotrauma patients than attenuation. What is unknown is the degree to which variance is affected by changes in extracerebral blood flow. Furthermore, the importance of acquiring the arterial input function (AIF) on quantitative analysis of t...

There are a wide variety of scientific contribution rating indices including the impact factor and h-index. These are used for quantitative analyses on research papers published in the past, and therefore unable to incorporate in the assessment the growth, or deterioration, of the research area: whether the research area of a particular paper is in decline or conversely in a growing trend. Othe...

Platelet MAO activity of 30 male drug free chronic schizophrenics (RDC), 30 male first degree relative of these patients and31 age matched male healthy controls was studied. Analysis of variance revealed that no significant differences existed between the three groups. There was high correlation between the enzyme activily of probands and first degree relatives. Presence or absence of auditory ...

The present study examined the degree to which demographic, human capital,motivational, organizational, and industry/region variables predicted executive career success. Career success was assumed to comprise objective (pay, ascendancy) and subjective (job satisfaction, career satisfaction) elements. Results obtained from a sample of 1,388 U.S.executives suggested that demographic, human capita...

We develop and implement a portfolio optimization method for building investment portfolios that dominate a given benchmark index in terms of third-degree stochastic dominance. Our approach relies on the properties of the semi-variance function, a re nement of an existing `superconvex' dominance condition and quadratic constrained programming. To reduce the computational burden in large-scale a...

Portfolio selection is an important issue for researchers and practitioners. In this paper, under the assumption that security returns are given by experts' evaluations rather than historical data, we discuss the portfolio adjusting problem which takes transaction costs and diversification degree of portfolio into consideration. Uncertain variables are employed to describe the security returns....

We develop and apply a multilevel modeling approach that is simultaneously capable of assessing multigroup and multiscale segregation in the presence of substantial stochastic variation that accompanies ethnicity rates based on small absolute counts. Bayesian MCMC estimation of a log-normal Poisson model allows the calculation of the variance estimates of the degree of segregation in a single o...

We investigate how people allocate a limited set of resources between multiple risky prospects. We found that only a small percentage of decisions followed some form of naive diversification or mean-variance optimization. In general, people were less mean-variance optimal than a naive 1/N heuristic. Aspects of choice sets, such as domain, skew, and second order stochastic dominance, affected re...
