Background and aims: The TEMPS-A scale is a self-evaluation measure which assesses five affective temperaments. This study is a comparative analysis of affective temperament types in different educational fields, and the first validation of the Serbian version of the TEMPS-A. Methods: The TEMPS-A questionnaire has been adapted following the translation-back translation methodology from English to Serbian. It was then administered to 770 undergraduate students from eight different faculties. Results: Five factors were extracted through Principal Component Analysis (Varimax rotation), each including ten items with loadings above 0.40. The internal consistency of this abbreviated 50-item scale was α=0.77 and the average test-retest coefficient (rho=0.82) indicates a stable reliability. The correlations among the temperaments ranged from weak to moderate, with the highest positive correlations obtained between the depressive and cyclothymic, and, depressive and anxious scales. The highest score was detected among the hyperthymic (0.64) and lowest among the depressive temperament (0.15). The male participants attained significantly higher scores for the hyperthymic temperament, while female scored significantly higher on the depressive and anxious temperaments. The students of physical education showed significantly lower results on the depressive and anxious subscales and higher on the hyperthymic, in comparison to other educational fields. Limitations: The student sample is not representative of the general population, therefore further investigation in older population would be necessary for the evaluation of norms in additional age categories. The external validation with other personality scales has not been the subject of this research, but will be a part of some future studies. Conclusions: The Serbian 50-item version of the TEMPS-A showed good overall internal consistency and reliability, and the results generally cohere with those from previously validated versions in other languages. © 2013 Elsevier B.V.

Globalization and process improvement initiatives are forcing organisations to evaluate and optimize cross-company processes rather than individual entities. Supply chain management (SCM) became critical management approach for integrated control over goods, information, and money within business networks. This demands a new quality management approach which enables delivery of high quality products and services in the right place, in a timely fashion, and cost effectively. This paper argues the needs for closed-loop quality management in supply chains, analyses existing quality models, and proposes the comprehensive framework for supply chain excellence that unifies business and technology domain.

This paper investigates the possibility of distinguishing between the effects of radiation coming from two or more radio active so topes, by using methods of statistical mathematics. The procedure uses a mixed distribution of an additive type. Mathematical treatment is demonstrated herein on an example of analysis of composite radiation from two radioactive sources. Source

Transmission characteristics of multimode W-type optical fibers (doubly clad fibers with three layers) are investigated by solving the time-dependent power flow equation. A numerical solution has been obtained by the explicit finite difference method. Results show how the bandwidth in W-type optical fibers varies with depth and width of the intermediate layer for different coupling strengths and excitations. The trade-off between the bandwidth and steady-state loss is also specified. Such characterization of these fibers is consistent with their manifested effectiveness in reducing modal dispersion and bending loss. © 2013 Elsevier Ltd. Source

Soil of arable land and meadows from the Ap horizon, taken from ten different localities, were investigated for different forms of Fe, including total (HF), pseudo-total (HNO3), 0.1 M HCl extractable and DTPA (diethylenetriaminepentaacetic acid)-extractable. A sequential fractional procedure was employed to separate the Fe into fractions: water soluble and exchangeable Fe (I), Fe specifically adsorbed with carbonates (II), reducibly releasable Fe in oxides (III), Fe bonded with organic matter (IV) and Fe structurally bonded in silicates (residual fraction) (V). The soil pH, cation exchange capacity, and size fractions (clay and silt) had a strongest influence on the distribution of the different forms of Fe. The different extraction methods showed similar patterns of the Fe content in arable and meadow soils. However, the DTPA iron did not correspond with the total iron, which confirms the widespread incidence of irondeficiency in vertisols is independent of the total iron in soils. The amount of exchangeable (fraction I) and specifically adsorbed (II) iron showed no dependence on its content in the other fractions, indicating low mobility of iron in vertisols. The strong positive correlation (r = 0.812 and 0.956) between the content of iron in HNO3 and HF and its contents in the primary and secondary minerals (fraction - V) indicate a low content of plant accessible iron in the vertisol. The sequential fractional procedure was confirmed as suitable for accessing the content and availability of iron in the vertisols of Serbia. Source
