Transnationality and Social Integration within Lifestyle Migration. A comparative study of two cases in Mexico and Spain

International mobility in search of amenity spaces for long-stay tourism is a growing phenomenon. U.S. citizens have practiced this lifestyle migration for decades to Latin American countries, especially to Mexico. British citizens move to Spain for similar reasons. In this paper we make a comparative analysis of these two international contexts in order to gain greater insight into the diversity and breadth of this type of migration. The study uses quantitative surveys administered at each field site. First, we analyze the phenomenon of U.S. citizens’ mobility to Mazatlán, Mexico. Second, we analize citizens from the United Kingdom residing in El Campello, Spain. In particular we compare their socio-demographic profiles, transnational practices and some patterns of social integration.

Simultaneous synthesis of work exchange networks with heat integration

The optimal integration of work and its interaction with heat can represent large energy savings in industrial plants. This paper introduces a new optimization model for the simultaneous synthesis of work exchange networks (WENs), with heat integration for the optimal pressure recovery of process gaseous streams. The proposed approach for the WEN synthesis is analogous to the well-known problem of synthesis of heat exchanger networks (HENs). Thus, there is work exchange between high-pressure (HP) and low-pressure (LP) streams, achieved by pressure manipulation equipment running on common axes. The model allows the use of several units of single-shaft-turbine-compressor (SSTC), as well as stand-alone compressors, turbines and valves. Helper motors and generators are used to respond to any demand and excess of energy. Moreover, between the WEN stages the streams are sent to the HEN to promote thermal recovery, aiming to enhance the work integration. A multi-stage superstructure is proposed to represent the process. The WEN superstructure is optimized in a mixed-integer nonlinear programming (MINLP) formulation and solved with the GAMS software, with the goal of minimizing the total annualized cost. Three examples are conducted to verify the accuracy of the proposed method. In all case studies, the heat integration between WEN stages is essential to improve the pressure recovery, and to reduce the total costs involved in the process.

La migración residencial de noreuropeos en España

El proceso de unificación europea ha facilitado la aparición de nuevos flujos migratorios entre los distintos Estados. Uno muy significativo lo forman los noreuropeos (británicos y alemanes, principalmente) que se trasladan a los países mediterráneos. En este artículo se analizan los problemas que enfrentan los inmigrantes residenciales noreuropeos en el sur de España a la hora de establecer vínculos con la sociedad española. Con este fin, se lleva a cabo un estudio en el municipio de San Miguel de Salinas, ubicado en el sudeste del país. La perspectiva metodológica articula la investigación cuantitativa con la cualitativa. Los hallazgos obtenidos muestran cómo la barrera idiomática esconde en realidad un entramado de relaciones entre aspectos socioespaciales, políticos y económicos. Se configura así un sistema que dificulta el establecimiento de interacciones entre los residentes españoles y los noreuropeos, generando además procesos de fragmentación social.

Green education using open educational resources (OER): setting up a green OER repository

A wealth of open educational resources (OER) focused on green topics is currently available through a variety of sources, including learning portals, digital repositories and web sites. However, in most cases these resources are not easily accessible and retrievable, while additional issues further complicate this issue. This paper presents an overview of a number of portals hosting OER, as well as a number of “green” thematic portals that provide access to green OER. It also discusses the case of a new collection that aims to support and populate existing green collections and learning portals respectively, providing information on aspects such as quality assurance/collection and curation policies, workflow and tools for both the content and metadata records that apply to the collection. Two case studies of the integration of this new collection to existing learning portals are also presented.

Microfoundations of strategic management: Toward micro–macro research in the resource-based theory

Over the last few years, a new stream of research has emerged in the field of strategic management which focuses on the analysis of its microfoundations. This line of research analyzes strategic topics examining their foundations rooted in individual actions and interactions. The main purpose of this paper is to examine this emerging literature of microfoundations, indicating its usefulness and main characteristics. Through a systematic literature review, this paper contributes to the field by identifying the main areas studied, the benefits and potential of this approach, and some limitations and criticisms. Moreover, the paper studies how the integration of micro and macro aspects in strategy research may be carried out, examining several works that use a multilevel approach. Some methodological approaches that may help to effect this integration are indicated. These aspects will be analyzed in relation to the resource-based theory.

La molécula conductual de relaciones públicas en la comunicación gubernamental con los inmigrantes en España

La afluencia creciente de inmigrantes en España conforma una nueva estratificación social. De todos los actores que intervienen en este proceso migratorio y la integración de los acogidos, el Gobierno Central español tiene una responsabilidad legal, pero también comunicacional. De ahí que se plantee el análisis de cómo se diseña y se elaboran tres herramientas oficiales del Ministerio de Trabajo e Inmigración desde la disciplina de las relaciones públicas y, en concreto, desde las relaciones con los inmigrantes considerados públicos minoritarios. La conducta de comunicación del Gobierno que este trabajo evidencia deja entrever una estrategia de relaciones públicas poco definida.
