A data driven study of relationships between relief and farmland abandonment in a Mediterranean region

The environmental, cultural and socio-economic causes and consequences of farmland abandonment are issues of increasing concern for researchers and policy makers. In previous studies, we proposed a new methodology for selecting the driving factors in farmland abandonment processes. Using Data Mining and GIS, it is possible to select those variables which are more significantly related to abandonment. The aim of this study is to investigate the application of the above mentioned methodology for finding relationships between relief and farmland abandonment in a Mediterranean region (SE Spain).We have taken into account up to 28 different variables in a single analysis, some of them commonly considered in land use change studies (slope, altitude, TWI, etc), but also other novel variables have been evaluated (sky view factor, terrain view factor, etc). The variable selection process provides results in line with the previous knowledge of the study area, describing some processes that are region specific (e.g. abandonment versus intensification of the agricultural activities). The European INSPIRE Directive (2007/2/EC) establishes that the digital elevation models for land surfaces should be available in all member countries, this means that the research described in this work can be extrapolated to any European country to determine whether these variables (slope, altitude, etc) are important in the process of abandonment.

Affecting Factors of Public Employees’ Ganizational Commitment

Purpose – The aim of this chapter is to shed some light on the antecedents of organizational commitment, the mediating role of job engagement and job satisfaction as determinants of organizational commitment within the public sector environment, and the effects that national cultural values may have on these relationships. Approach – This paper presents a review of the works that, from both theoretical and empirical points of view, explore the affecting factors of public employees’ organizational commitment in an international setting. Findings – A comprehensive model has been developed, detailing the expectations on the influence that these factors might have on public employees’ level of commitment, either as mediators or moderators. Research limitations/implications – The main limitation is the paper’s theoretical nature; the subsequent implication is a future empirical research that may prove or disprove these theoretical findings. In addition, there are some other possible mediating factors and antecedents which may be of interest for future researchers. Originality/value – This comprehensive review of the extant literature may provide academics and public managers with a deeper comprehension of how organizational commitment might be achieved, and why some practices may or may not be transferrable from one country to another.

La elección entre tipos de inversión directa en el exterior: evidencia empírica de las empresas españolas en China

Una de las cuestiones que más interés despierta entre los investigadores del campo de la internacionalización empresarial es la selección de la estrategia de entrada en un país extranjero. Actualmente, China es uno de los destinos que está cobrando una mayor relevancia en la expansión internacional de muchas empresas. En ese contexto, este trabajo examina la influencia de diversos factores empresariales sobre el nivel de compromiso asumido por las compañías españolas que han entrado en China a través de inversiones directas.
