Since the United Nations approved the eight Millennium Development Goals in 2000 and, 15 years later, the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs), the highest political institutions in the world have not stopped worrying about achieving the sustainability of the planet. Also in 2015, the European Commission prepared the European Union Action Plan for the Circular Economy, seeking a transition towards a less linear economy, in which products, materials, and resources are kept in the system for as long as possible and in which the generation of waste is minimized.Since then, the European Union has continued issuing reports and communications to accelerate this process in search of a circular economy, making continuous references to the fact that, through circular economy initiatives, the SDGs would be fulfilled. In this context, the objectives of this paper are 1) to determine, through exploratory factor analysis and correlation analysis, whether there is a statistically significant relationship between circular economy initiatives undertaken in the EU and compliance with the SDGs; 2) to check, through a cluster analysis, if there are homogeneous groups of countries worldwide in terms of compliance with the SDGs; and 3) using this same technique, to check whether the countries that make up the EU achieve similar results in terms of compliance with the SDGs.

Personas y otros factores críticos en el aprendizaje organizativo en la industria hotelera: un enfoque de contingencias María del Mar Alonso-Almeida AbstractOrganizational learning is instrumental to successful adaptation to today's changing environment. Research on the subject in the context of the hotel industry is scant, however. The present study surveyed 147 Spanish hotels to determine the extent to which they drew from internal and external drivers and cultural and technological enablers and the level of organizational learning attained. These hotels were also characterized by the contingency factors most relevant to the industry and, based on the results, grouped into four clearly distinct clusters. An analysis of the groupings confirmed statistically significant inter-cluster differences. The empirical evidence gathered suggests that while all the hotel establishments studied stressed organizational learning, individual features determined differences in how successfully it is implemented. The inter-cluster differences identified suggest that the valuation of organizational learning varies with hotel type and, therefore, different organizational learning strategies must be implemented to attain higher performance.Keywords: Organizational learning, contingency factors, learning enablers, internal drivers, external. ResumenEn la actualidad, el aprendizaje organizativo es clave para adaptarse con éxito al entorno cambiante. Sin embargo, la investigación previa de este tema aplicado a la industria hotelera es escasa. Por ello, este estudio busca identificar el alcance de los factores conductores de adquisición de conocimiento, tanto internos como externos; analizar la adopción de facilitadores culturales y tecnológicos, y determinar el nivel de aprendizaje organizativo alcanzado por 147 establecimientos hoteleros ubicados en España. Además, este trabajo caracteriza los establecimientos hoteleros atendiendo a los factores de contingencia más relevantes en el sector. Sobre la base de estos factores, se desarrolló un análisis cluster para identificar la existencia de distintos grupos, resultando cuatro grupos claramente diferenciados, estudiándose las diferentes características de cada uno de ellos. Los resultados son relevantes ya que proporcionan evidencia empírica de que, aunque todos los establecimientos hoteleros estudiados potencian el aprendizaje organizativo, sus características propias sugieren diferencias en su grado de desarrollo y, por tanto, en su efectividad.Palabras clave: Aprendizaje organizativo, factores de contingencia, potenciadores del aprendizaje, factores conductores internos, factores conductores externos.
