Purpose In the present work, lean and resilient practices applied to supply chains are studied in order to evaluate their impact on the three dimensions of sustainability. Additionally, the mutual impact of lean and resilient supply chain practices is investigated. The paper aims to discuss these issues. Design/methodology/approach The aerospace sector and its supply chain are chosen, since lean and resilient practices have been proven relevant in the sector. A methodology based on Interpretive Structural Modeling approach is applied in order to identify the existing relationships between lean and resilient supply chain practices and their impact on the three different dimensions of sustainability. Findings The results reveal synergetic effects between lean and resilient practices. The former practices act as drivers of the latter practices. Hence, lean practices lead to direct and indirect effects in achieving supply chain sustainability. Research limitations/implications The relationship between lean and resilient practices has been studied for the aerospace sector. Different sectors may lead to different results as the practices considered important in each sector may differ as well as the way in which each practice is implemented. Originality/value This study highlights the relationship existing between lean and resilient supply chain practices and their impact on sustainability. Additionally, several managerial implications are drawn out to help managers make better decisions.

<p class="Abstract">With growing sustainability concern in mind, firms seek to implement reverse logistic systems in their operations. However, if these practices were not properly implemented, they would be costly and even ineffective. In order to guide company efforts, the present study provide a comprehensive framework based on two dimensions. On one hand, it suits a reverse logistic management model stage-by-stage. On the other hand, the framework brings together concrete measures to optimize SC sustainability from three perspectives: operative, economical and environmental. The proposed framework thus allow to balance reverse logistic practices and SC sustainability. Furthermore, we validated it by analysing six real case in different industries. Findings highlight how reverse logistic activities may improve each SC sustainability dimension.</p>

El presente trabajo analiza los efectos de la aplicación de la técnica de "jigsaw", puzzle o rompecabezas de Aronson en la adquisición de competencias por parte de estudiantes universitarios. Más concretamente buscamos determinar qué competencias sistémicas, instrumentales e interpersonales se adquieren más fácilmente al implantar "jigsaw" en el proceso de enseñanza-aprendizaje. Los resultados alcanzados muestran que esta técnica de aprendizaje cooperativo facilita en mayor medida la adquisición de competencias sistémicas e instrumentales en comparación con las interpersonales. Dentro de las competencias sistémicas, la que desarrollan con más facilidad los alumnos es la denominada metareflexión; es decir, el aprendizaje progresivo por repetición. En el grupo de competencias instrumentales, destacan la interacción entre compañeros, las habilidades comunicativas del alumno, la participación, la ayuda en la resolución de conflictos entre compañeros surgidos durante la dinámica y la mejora de la instrucción directa. Finalmente, en relación a las competencias interpersonales, la más desarrollada es el sentido de la responsabilidad del alumno.
