Developing Semantic Rich Internet Applications with the Sm4RIA Extension for OIDE

This paper introduces the Sm4RIA Extension for OIDE, which implements the Sm4RIA approach in OIDE (OOH4RIA Integrated Development Environment). The application, based on the Eclipse framework, supports the design of the Sm4RIA models as well as the model-to-model and model-to-text transformation processes that facilitate the generation of Semantic Rich Internet Applications, i.e., RIA applications capable of sharing data as Linked data and consuming external data from other sources in the same manner. Moreover, the application implements mechanisms for the creation of RIA interfaces from ontologies and the automatic generation of administration interfaces for a previously design application.

Applying model-driven engineering to the development of Rich Internet Applications for Business Intelligence

Business Intelligence (BI) applications have been gradually ported to the Web in search of a global platform for the consumption and publication of data and services. On the Internet, apart from techniques for data/knowledge management, BI Web applications need interfaces with a high level of interoperability (similar to the traditional desktop interfaces) for the visualisation of data/knowledge. In some cases, this has been provided by Rich Internet Applications (RIA). The development of these BI RIAs is a process traditionally performed manually and, given the complexity of the final application, it is a process which might be prone to errors. The application of model-driven engineering techniques can reduce the cost of development and maintenance (in terms of time and resources) of these applications, as they demonstrated by other types of Web applications. In the light of these issues, the paper introduces the Sm4RIA-B methodology, i.e., a model-driven methodology for the development of RIA as BI Web applications. In order to overcome the limitations of RIA regarding knowledge management from the Web, this paper also presents a new RIA platform for BI, called RI@BI, which extends the functionalities of traditional RIAs by means of Semantic Web technologies and B2B techniques. Finally, we evaluate the whole approach on a case study—the development of a social network site for an enterprise project manager.

Las encuestas autoadministradas por internet. Un estudio de caso: “las familias adoptivas y sus estilos de vida”

España se convierte, en 2004, en el segundo país del mundo en adopción internacional propiciando que la familia adoptiva adquiera una gran visibilidad y relevancia social. El artículo presenta los hallazgos obtenidos a partir de la administración online, a madres y padres adoptivos españoles, de la encuesta Web “Las familias adoptivas y sus estilos de vida”. En concreto, se exponen los resultados obtenidos sobre las actitudes, opiniones y percepción de la norma social en materia de adopción. Este análisis permite explorar los factores explicativos que determinan que un subconjunto de la población opte por la adopción al tiempo que nos acerca a la comprensión sociológica tanto del incremento de las adopciones en España como de las familias adoptivas. Adicionalmente, el artículo expone los aspectos técnicos relacionados con el diseño y aplicación de la encuesta on-line con el objetivo de evidenciar que, a pesar de las limitaciones propias de esta forma de aplicación, esta arrojar luz sobre el proceso de adopción internacional, escasamente explorado en la investigación sociológica española con encuestas.

The impact of the internet on the pricing strategies of the European low cost airlines

This study seeks to analyse the price determination of low cost airlines in Europe and the effect that Internet has on this strategy. The outcomes obtained reveal that both users and companies benefit from the use of ICTs in the purchase and sale of airline tickets: the Internet allows consumers to increase their bargaining power comparing different airlines and choosing the most competitive flight, while companies can easily check the behaviour of users to adapt their pricing strategies using internal information. More than 2500 flights of the largest European low cost airlines have been used to carry out the study. The study revealed that the most significant variables for understanding pricing strategies were the number of rivals, the behaviour of the demand and the associated costs. The results indicated that consumers should buy their tickets before 25 days prior to departure.

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.

Current status of research on school refusal

School refusal behavior refers to the avoidance of a child attending school and/or persistent difficulty staying in the classroom throughout the school day. Based on a review of the scientific literature, the aim of this study is to describe the current state of research on school refusal, differentiating between the findings and progress made in Spain from those achieved in the international field. For this purpose, the significance of this phenomenon, in addition to associated risk factors and variables, will be reviewed in the child and youth population. In turn, the commonly used assessment methods and most recommended treatment proposals, mainly based on cognitive behavioral therapy, are discussed. The results reveal several gaps and subjects for debate in some areas of knowledge about school refusal behavior, with differences being found between Spanish and international studies. In conclusion, future studies and challenges in this field are required.

Uso de Internet y prácticas políticas de los jóvenes españoles

A partir de un análisis secundario de los microdatos procedentes del estudio 2.889 del Centro de Investigaciones Sociológicas de España, pretendemos observar la posible relación entre el uso de Internet por parte de los jóvenes y sus prácticas políticas. En concreto, las variables disponibles permiten estudiar tres aspectos fundamentales: si existe relación entre la frecuencia de uso de Internet y la participación política; si el grado de participación política en el espacio virtual se correlaciona con la participación fuera de este espacio; y si se observan diferencias en términos de participación política online según variables sociodemográficas. Entre los resultados obtenidos podemos destacar la existencia de una relación estadísticamente significativa entre una mayor frecuencia de uso de Internet y una mayor implicación política tanto en el espacio virtual como offline.
