Objective This study explored the dimensionality and measurement invariance of the 25-item Connor-Davidson Resilience Scale (CD-RISC; Connor & Davidson, 2003) across samples of adult (n = 321; aged 20–36) and adolescent (n = 199; aged 12–18) Australian cricketers. Design Cross-sectional, self-report survey Methods An online, multi-section questionnaire. Results Confirmatory factor and item level analyses supported the psychometric superiority of a revised 10-item, unidimensional model of resilience over the original 25-item, five-factor measurement model. Positive and moderate correlations with hardiness as well as negative and moderate correlations with burnout components were evidenced thereby providing support for the convergent validity of the unidimensional model. Measurement invariance analyses of the unidimensional model across the two age-group samples supported configural (i.e., same factor structure across groups), metric (i.e., same pattern of factor loadings across the groups), and partial scalar invariance (i.e., mostly the same intercepts across the groups). Conclusion Evidence for a psychometrically sound measure of resilient qualities of the individual provides an important foundation upon which researchers can identify the antecedents to and outcomes of resilience in sport contexts.

Soft error has become one of the major areas of attention with the device scaling and large scale integration. Lot of variants for superscalar architecture were proposed with focus on program re-execution, thread re-execution and instruction re-execution. In this paper we proposed a fault tolerant micro-architecture of pipelined RISC. The proposed architecture, Floating Resources Extended pipeline (FREP), re-executes the instructions using extended pipeline stages. The instructions are re-executed by hybrid architecture with a suitable combination of space and time redundancy.

This paper describes a novel RISC microprocessor that can be utilised to rapidly develop a reprogrammable and high performance embedded security-processing system in SoC designs. Generic and innovative algorithm-specific instructions have been developed for a wide range of private-key and hash algorithms. To the authors' knowledge, this is the first generic cryptographic microprocessor to be reported in the literature.

A new conceptualization of the investments is defended in accordance with the nature of the uncertainty. The results of this conceptualization offer a theory of the investment compatible with the concept of intrinsec value that is been able expressed in mathematical model. This model is an alternative to the named 'pricing models'.

En aquest article es presenten les diferents mesures que la societat gironina ha anat adoptant al llarg dels anys per fer front al risc d'avingudes, fent especial èmfasi, però, a les mes recents. Aquestes mesures d'adaptació poden classificar-se en dos grans grups, que no son ni molt menys excloents: les mesures estructurals, integrades bàsicament per les obres hidràuliques, i les mesures no-estructurals, mes dirigides a l'àmbit del comportament individual i col·lectiu enfront el risc. Finalment es realitzarà una valoració de l'estat actual del sistema de defenses de la ciutat i es proposaran un seguit d'alternatives

En aquest article ens proposem estudiar, des d'una perspectiva històrica, un dels aspectes de la problemàtica mediambiental que més afecten les societats humanes materialment i emotiva: les catàstrofes naturals i, més concretament, les inundacions fluvials. L'hmbit d'estudi escollit és Girona, ciutat on la complexa hidrologia de superfície (quatre rius, el Ter, l'Onyar, el Güell i el Galligans, a més d'altres cursos menors d'aigua, travessen la ciutat) i, sobretot, la vulnerabilitat creixent de la societat gironina al risc d'avingudes com a resultat de la important ocupació de les planes al.luvials, han fet de les inundacions una constant histbrica de la qual tenim multitud d'exemples des que existeixen documents escrits
