La tecnología ha devenido, hoy en día, un factor primordial de cuyo adecuado empleo depende en gran medida el funcionamiento de los diversos contextos del aprendizaje humano. La teoría ecológica del aprendizaje considera el factor tecnológico como un componente especialmente relevante. Además, las tecnologías digitales están potenciando el desarrollo de nuevas oportunidades de aprendizaje que trascienden las fronteras temporales y geográficas, y propician sistemas que rompen el encorsetamiento de las estructuras de formación formal dando paso a ambientes flexibles, expandidos y diversos desde los que se favorecen mecanismos de aprendizaje informal. Desde esta perspectiva, y de cara a la construcción de tales contextos, resulta conveniente disponer de un marco de referencia paradigmático acerca de las oportunidades que las TIC puedan presentar y, paralelamente, valorar también la problemática asociada a su empleo. Para la identificación de este elenco de affordances tecnológicas, hemos seguido el método Delphi, en cuyo desarrollo han colaborado diversos expertos nacionales e internacionales. El análisis de resultados confirma el papel destacado de los usos tecnológicos en los contextos de aprendizaje actuales, y desvela su funcionamiento en íntima relación con los demás componentes que los integran. Resaltan no solo los aspectos potenciadores del aprendizaje, como son, entre otros, la facilitación de diversas herramientas de comunicación, acceso e intercambio de información, su potencialidad para la creación de vínculos entre personas y comunidades, y la transformación de los roles educativos. Se desvela también la emergencia de ciertas barreras en su empleo, como la ausencia de estrategias de uso. En este sentido, y siempre sobre la base del análisis de la configuración concreta de cada contexto, de sus elementos e interrelaciones, puede manejarse un marco de referencia general de affordances tecnológicas que sirva de guía para el desarrollo de una ecología de aprendizaje auténtica. Currently technology has become a primary factor in the various contexts of human learning, that depend, in a large extend, on the proper use of ICT. The ecological theory of learning considers the technological factor as a particularly relevant component of learning contexts. In addition, digital technologies are driving the development of new learning opportunities that transcend temporal and geographical borders and favor systems that break the confinement of formal training structures, giving way to flexible, expanded and diverse environments that generate informal learning mechanisms. From this perspective and with a view to the construction of such contexts, it seems convenient to have a paradigmatic frame of reference of the opportunities that ICTs can present. To identify this list of technological affordances, we have proceed through the Delphi method, in whose development various national and international experts have collaborated. The analysis of results confirms the prominent role of ICT in modern learning contexts and their operation in close relationship with the other components that comprise them. Their affordances for improving learning can be highlighted, such as, among others, the facilitation of various communication tools, access and exchange of information, their potential for creating links between people and communities, and the transformation of educational roles. In this sense, and always on the basis of the analysis of the specific configuration of each context in question, its elements and interrelations, a general framework of technological affordances can be used to serve as a guide for the development of an authentic learning ecology.

Companies increasingly regard relationships with other companies as a source of competitive advantage. Relationships constitute a context in which the firm may learn and build absorptive capacity. This study provides an in-depth explanation of the key mechanisms that interlace the different learning processes leading to innovations in a relational context. A theoretical elaboration of these mechanisms precedes their empirical study within four customer-supplier dyads, centred on two focal customer organizations.The article contributes by discussing how the mechanisms act and interact to create absorptive capacity for a focal firm across relationships. We find that structural learning mechanisms, while necessary are not sufficient to explain variation in the presence of absorptive capacity across different learning contexts. Cultural, psychological and policy learning mechanisms complement the picture. From the empirical analysis we derive propositions to guide further research into the creation of absorptive capacity in a relational context.


Arriving to the final destination of the journey started in chapter 1, this concluding chapter represents a brief reflection of the key considerations/contributions of the book and, simultaneously, provides a guidance for future research directions. From an ecological standpoint, the key purpose of this book was to systemically understand the essential issues related to the trends and fuzzy logic-based modeling perspectives of collaborative and blended learning. In addition, the emancipation of collaborative and blended learning environments here is established as a potential contribution to the 21st century learning contexts. In this vein, comprehension of the potentialities of the proposed fuzzy logic-based modeling approaches and the way they could be transferred to tackle real problems in the educational context, contributes to the establishment of a learning ecology for reflection and rethinking upon the intelligence of the online learning environments as current and future constructs.

Landslides are generated by natural causes and by human action, causing various geomorphological changes as well as physical and socioeconomic loss of the environment and human life. The study, characterization and implementation of techniques are essential to reduce land vulnerability, different socioeconomic sector susceptibility and actions to guarantee better slope stability with a significant positive impact on society. The aim of this work is the bibliometric analysis of the different types of landslides that the United States Geological Survey (USGS) emphasizes, through the SCOPUS database and the VOSviewer software, for the analysis of their structure, scientific production, and the close relationship with several scientific fields and its trends. The methodology focuses on: (i) search criteria; (ii) data extraction and cleaning; (iii) generation of graphs and bibliometric mapping; and (iv) analysis of results and possible trends. The study and analysis of landslides are in a period of exponential growth, focusing mainly on techniques and solutions for the stabilization, prevention, and categorization of the most susceptible hillslope sectors. Therefore, this research field has the full collaboration of various authors and places a significant focus on the conceptual evolution of the landslide science.

The solution strategies of preschool children solving mental-rotation tasks were analyzed in two studies. In the first study n = 111 preschool children had to demonstrate their solution strategy in the Picture Rotation Test (PRT) items by thinking aloud; seven different strategies were identified. In the second study these strategies were confirmed by latent class analysis (LCA) with the PRT data of n = 565 preschool children. In addition, a close relationship was found between the solution strategy and children’s age. Results point to a stage model for the development of mental-rotation ability as measured by the PRT, going from inappropriate strategies like guessing or comparing details, to semiappropriate approaches like choosing the stimulus with the smallest angle discrepancy, to a holistic or analytic strategy. A latent transition analysis (LTA) revealed that the ability to mentally rotate objects can be influenced by training in the preschool age.

Mental speed (MS) and sustained attention (SA) are theoretically distinct constructs. However, tests of MS are very similar to SA tests that use time pressure as an impeding condition. The performance in such tasks largely relies on the participants’ speed of task processing (i.e., how quickly and correctly one can perform the simple cognitive tasks). The present study examined whether SA and MS are empirically the same or different constructs. To this end, 24 paper-pencil and computerized tests were administered to 199 students. SA turned out to be highly related to MS task classes: substitution and perceptual speed. Furthermore, SA showed a very close relationship with the paper-pencil MS factor. The correlation between SA and computerized speed was considerably lower but still high. In a higher-order general speed factor model, SA had the highest loading on the higher-order factor; the higher-order factor explained 88% of SA variance. It is argued that SA (as operationalized with tests using time pressure as an impeding condition) and MS cannot be differentiated, at the level of broad constructs. Implications for neuropsychological assessment and future research are discussed.
