Digging up the frequency of phrasal verbs in English for the Police: the case of "up"

The present study focuses on the frequency of phrasal verbs with the particle up in the context of crime and police investigative work. This research emerges from the need to enlarge McCarthy and O’Dell’s (2004) scope from purely criminal behavior to police investigative actions. To do so, we relied on a corpus of 504,124 running words made up of spoken dialogues extracted from the script of the American TV series Castle shown on ABC since 2009. Based on Rudzka-Ostyn’s (2003) cognitive motivations for the particle up, we have identified five different meaning extensions for our phrasal verbs. Drawing from these findings, we have designed pedagogical activities for those L2 learners that study English at the Police Academy.

El rol de los actores subnacionales en la construcción de la política exterior de Japón. Estudio de caso: La disputa territorial por las islas Senkaku/Diaoyu entre Japón y China (2001-2014)

El presente estudio de caso tiene como objetivo analizar la influencia de la gobernación de Tokio en la formulación de la política exterior de Japón durante la disputa territorial por las islas Senkaku/Diaoyu. Para ello, se identifican los puntos más relevantes de la política exterior de seguridad de Japón después de la Segunda Guerra Mundial. Se hace un énfasis en la política bilateral de seguridad sino-japonesa, con el fin de ubicar el conflicto territorial por las islas Senkaku/Diaoyu como un punto importante en la agenda internacional de seguridad de ambos países. Se estudia y analiza el concepto de paradiplomacia; articulado, a su vez, por los conceptos de identidad y rol en política exterior de la perspectiva teórica del Constructivismo de las Relaciones Internacionales, para así analizar la influencia de Tokio en el manejo de la política exterior de Japón en el marco del conflicto territorial por las islas Senkaku/Diaoyu.

Detailed analysis of a conservative difference approximation for the time fractional diffusion equation

Diffusion equations that use time fractional derivatives are attractive because they describe a wealth of problems involving non-Markovian Random walks. The time fractional diffusion equation (TFDE) is obtained from the standard diffusion equation by replacing the first-order time derivative with a fractional derivative of order α ∈ (0, 1). Developing numerical methods for solving fractional partial differential equations is a new research field and the theoretical analysis of the numerical methods associated with them is not fully developed. In this paper an explicit conservative difference approximation (ECDA) for TFDE is proposed. We give a detailed analysis for this ECDA and generate discrete models of random walk suitable for simulating random variables whose spatial probability density evolves in time according to this fractional diffusion equation. The stability and convergence of the ECDA for TFDE in a bounded domain are discussed. Finally, some numerical examples are presented to show the application of the present technique.
