Vestibular selection criteria development

The experimental elicitation of motion sickness using a short arm centrifuge or a rotating chair surrounded by a striped cylindrical enclosure failed to reveal any systematic group or consistent individual relationship between changes in heart rate, blood pressure, and body temperature and the appearance of symptoms of motion sickness. A study of the influence of vision on susceptability to motion sickness during sudden stop simulation shows that having the eyes open during any part of the sudden stop assessment is more stressful than having them closed throughout the test. Subjects were found to be highly susceptible to motion sickness when tested in free fall and in high force phases of flight. The effect of touch and pressure cues on body orientation during rotation and in parabolic flight are considered as sensory as well as motor adaptation

Assessing the Job Selection Criteria of Accounting Students: a Normative Approach

This research assessed to what extent final-year Muslim accounting students in Malaysia considered Islamic principles when choosing a job after graduation. 356 final-year Muslim accounting students in four Malaysian universities were surveyed using an open-ended job selection scenario. The result shows that reality does not live up to the ideal. Only 16% of the respondents apply Islamic principles in making a job selection decision. The remaining 84% are more concerned with other criteria such as personal interests, salary considerations, and company reputation

Selection Criteria for Sustainable Development Indicators

The selection of optimum number of indicators is the key to any Sustainable Development Indicator (SDI) research. Indicators, too less in number may be inadequate to convey the message and; too many may dilute the purpose. To arrive at a limited number of indicators from a larger set of potential ones, a set of criteria is applied. In the past SDI-initiatives, emphasis was not laid on structuring criteria; these were invariably considered in a linear way. This paper proposes a framework to organize criteria in a tree fashion at successive levels. For each level, the weights of a criterion relative to others are determined by following Analytical Hierarchy Process where experts opinions are considered. For aggregation of scores, displaced ideal method is proposed over linear additive model.What-How-Whom (WHW) framework, Value tree, Analytical Hierarchy Process, Displaced ideal

On selection criteria for problems with moving inhomogeneities

We study mechanical problems with multiple solutions and introduce a thermodynamic framework to formulate two different selection criteria in terms of macroscopic energy productions and fluxes. Studying simple examples for lattice motion we then compare the implications for both resting and moving inhomogeneities.Comment: revised version contains new introduction, numerical simulations of Riemann problems, and a more detailed discussion of the causality principle; 18 pages, several figure

Selection Criteria for the Honors Program in Azerbaijan

Designing effective selection procedures for honors programs is always a challenging task. In Azerbaijan, selection is based on three main criteria: (i) student performance in the centralized university admission test; (ii) student performance in the first year of studies; and (iii) student performance in the honors program selection test. This research identifies criteria most crucial in predicting student success in honors programs. An analysis was first conducted for all honors students. Results indicate that all three criteria used in the selection process are highly significant predictors of student success in the program. This same analysis was then applied separately for each degree program, demonstrating that not all criteria are significant for some programs. These results suggest that creating differentiated selection procedures for different degree programs might be more efficient

Selection criteria of diluents of tri-n-butyl phosphate for recovering neodymium(III) from nitrate solutions

The selection of a proper diluent should be based on several criteria such as the distribution ratio, phase disengagement time, cost, safety and environmental impact of the process. The effect of different diluents on the solvent extraction of Nd(III) by the neutral extractant tri-n-butylphosphate (TBP) from nitrate feed solutions was studied. The nature of the diluent had little effect on the extraction kinetics of Nd(III) by TBP above 2.5 min. In general, phase disengagement times were relatively shorter for aromatic diluents compared to aliphatic diluents. Conversely, extraction efficiencies were the highest for aliphatic diluents, slightly lower for mixed aliphatic-aromatic diluents and much lower for aromatic diluents. The poorer extraction efficiencies of aromatic diluents maybe due to the lower concentration of free extractant as a result of the stronger interactions of the diluent with water and/or of the diluent with the extractant. Under the experimental conditions, the differences in extraction between aliphatic and aromatic diluents decreased with increasing the salting-out effect of nitrate ions in the feed. At nitrate concentrations of 4.5 mol L−1 or more, the different diluents had a limited influence on the metal extraction with 1 mol L−1 TBP from feed solutions of 1 g L−1 Nd(III). Thus, under these conditions, the selection of the diluent can be preferably based on its cost, safety and biodegradability rather than on its physico-chemical properties
