The role of the internet in the cultural convergence: a theoretical analysis based on the dynamic-constructivist approach from the consumers’ online interactions perspective
This paper poses, from a theoretical perspective, the role that may have Internet as a key factor to foster the cultural convergence among countries. In this regard, we reflect about a central theoretic proposal, taking as main reference the dynamic constructivist approach. The gist of the paper goes down the lines of how shared values generated in the on-line communication processes developed by individuals (consumers) from different cultures-either between each other or between them and the medium-, can be passed on to every culture of origin, fostering their rapprochement in the long run.Internet, cultural interaction, values transference, cultural convergence, dynamic constructivist approach
Contribution of exclusive channels to the leading order HVP of the muon
We evaluate the contributions of
exclusive channels to the dispersion integral of the leading order HVP of the
muon anomalous magnetic moment. These channels are included in some way in
previous evaluations of the and
contributions to , where the vector resonances (decaying
into ) are assumed to be on-shell. Since the separation of
resonance and background contributions in a given observable is, in general, a
model-dependent procedure, here we use pseudoscalar mesons and the photon as
the and states of the -matrix, such that the cross section contains the
interferences among different contributing to the amplitudes. We find , where
uncertainties stem mainly from vector meson dominance model parameters.
Improved experimental studies of these exclusive channels in the whole range
below 2 GeV would reduce model-dependency
Organizational learning and innovation as sources of strategic fit
Purpose
The purpose of this paper is to analyze the roles played by organizational learning (OL) and innovation in organizations immersed in the processes of adaptation and strategic fit in dynamic and turbulent environments. The authors analyze whether OL and innovation act as sources of strategic fit, and whether strategic fit positively affects performance.
Design/methodology/approach
The authors use data from a survey of a representative sample of 204 respondents from European firms active in high-technology sectors (response rate: 10.42 percent) and structural equation modeling (using the EQS 6.1 program) to undertake a transversal study.
Findings
The model confirms that OL and the capacity to innovate positively influence managers’ decisions to adapt their organizations to changes in dynamic environments. The achievement of strategic fit, in turn, improves organizational performance. The authors propose considering the innovation climate as a facilitator of new product and process development, although the innovation climate is not a direct antecedent of fit.
Research limitations/implications
This study is limited by the fact that the analysis is cross-sectional and by the fact that all measures used are based on managers’ perceptions.
Practical implications
Managers should create and support an entrepreneurial culture that stresses continuous learning. They should also foster programs aimed at developing abilities, and promote the development of capabilities that facilitate acceptance of organizational change. Investments in building certain capabilities, such as OL and the capacity to innovate, are strategically justified, especially in turbulent environments.
Originality/value
This study is one of the first to investigate the complex interactions among OL, innovation, strategic fit, and performance. The results improve our understanding of the links between strategic fit and performance
Estudio experimental y numérico de uniones con angulares ejecutadas con perfiles europeos
In this paper, four specimens with different thickness of top and seat angle with double web angle connections are experimentally tested and numerically modeled. The model has been solved by means of Abaqus® finite element package. Moment rotation curves obtained from the experiments are compared with those obtained from FE models and good agreement is observed. These results validate this numerical modeling in order to use it in future studies on angle connections.En este artÃculo se presenta el ensayo experimental y el modelo numérico de cuatro uniones de estructura metálica realizadas con casquillos angulares de diferentes espesores. El problema se ha resuelto mediante el programa comercial de elementos finitos Abaqus®. Las curvas experimentales momento-rotación obtenidas concuerdan razonablemente con los resultados de los modelos propuestos, de modo que con este trabajo se ha establecido una base numérica sólida para estudios posteriores
Surgical treatment of benign parapharyngeal space tumours : presentation of two clinical cases and revision of the literature
Parapharyngeal space (PPS) tumours, most of them benign, account for some 0.5% of tumours of the head and neck. The importance of these tumours lies mainly in two aspects: on the one hand, the difficulty of early diagnosis, due to the lack of symptoms in the initial stages and, on the other, the extreme complications of performing surgery in the parapharyngeal region. This article discusses two clinical cases of parapharyngeal space tumours: a 45 year old man and a 60 year old woman. We revise the scientific literature and analyse the diagnostic and therapeutic procedures used, placing special emphasis on describing the different surgical approaches to the parapharyngeal space: transcervical, transcervical-transparotid, transpalatal or transoral, transmandibular and orbitozygomatic, all of which, used alone or combined with others, allow for complete resection of these tumours with minimum morbidity
Análisis cinemático del viraje en el esquà alpino de competición
Esta comunicación trata sobre la aplicación de la Biomecánica Deportiva como perspectiva
cientÃfica, al análisis cinemático del esquà alpino como objeto de estudio, y ha sido realizada
basándose en una situación real de competición como fue el Campeonato del Mundo de 1996
celebrado en Sierra Nevada (Granada). Para el análisis de la muestra, utilizamos la metodologÃa
y las tecnologÃas propias de la biomecánica Deportiva como son el método indirecto y las técnicas
fotogramétricas tridimensionales, basadas en la filmación del gesto deportivo utilizando el vÃdeo.
Los resultados obtenidos muestran la existencia de un patrón general de movimiento en la
muestra de esquiadoras analizadas en cuanto a las velocidades tangenciales medias del CG(S).del
sistema (esquiador más implementos). Entre las conclusiones, destacamos la existencia de una
reducción de la velocidad tangencial media resultante en el recorrido analizado que es mayor aún,
en el instante de paso del palo de viraje en particular y cuanto más curva es la trayectoria. Atendiendo
a la desviación tÃpica del comportamiento de la velocidad media resultante, podemos decir
que en este tramo de paso de la puerta encontramos las diferencias entre la técnica individual de
las esquiadoras analizadas.
