Internacionalización bancaria: paradigmas teóricos y teorías explicativas

Los diferentes tipos de actividades que se incluyen en el epígrafe debanca internacional, dificulta la existencia de una única teoríaexplicativa de la internacionalización bancaria. Por el contrario,desde diferentes aproximaciones se han propuesto teorías parcialesdirigidas a explicar aspectos particulares del fenómeno. El objetivoprincipal de este artículo es proporcionar una visión completa delestado actual de la investigación, con el énfasis especial de integrarestas teorías parciales en alguno de los dos grandes paradigmas de lainversión directa en el exterior.

Análisis de la eficacia de los saques de esquina en la copa del mundo de fútbol 2010. Un intento de identificación de variables explicativas

In soccer, dead-ball moves are those in which the ball is returned to play from a stationary position following an interruption of play. The aim of this study was to analyse the effectiveness of one such dead-ball move, namely corner kicks, and to identify the key variables that determine the success of a shot or header following a corner, thereby enabling a model of successful corner kicks to be proposed. We recorded 554 corner kicks performed during the 2010 World Cup in South Africa and carried out a univariate, bivariate and multivariate analysis of the data. The results indicated that corners were of limited effectiveness in terms of the success of subsequent shots or headers. The analysis also revealed a series of variables that were significantly related to one another, and this enabled us to propose an explanatory model. Although this model had limited explanatory power, it nonetheless helps to understand the execution of corner kicks in practical terms.
