    Efectos de la aplicación de "jigsaw" sobre la adquisición de competencias en dirección de operaciones // Effects of the "Jigsaw" Technique on Student' Learning Competences within Operations Management
    (https://www.upo.es/emch/portada, 2017) López Vargas, Cristina; Real, Juan C.
    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.------------------------------------The aim of this study was to determine the effects of the cooperative ``jigsaw'' method on generic competence-based training by university students. This specifically sought to understand how systemic, instrumental and interpersonal competences are more easily acquired by adopting ``jigsaw'' in the teaching-learning procedure. The results reveal that this cooperative learning method makes the development of systemic and instrumental competences easier to a greater extent than interpersonal ones. Meta-reflection or progressive rote learning achieved a highest score among systemic competences. Focusing our attention on the instrumental dimension, peer interaction, students' communication skills, participation, resolution of peer conflicts and direct instruction, these competences sty out from the rest. Finally, responsibility was the easiest competence in the interpersonal dimension.

    Achieving sustainability through the lean and resilient management of the supply chain
    (Emerald Publishing, 2019) Ruiz Benítez, Rocío; López Vargas, Cristina; Real, Juan C.
    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.

    Multilayer analysis of supply chain strategies’ impact on sustainability
    (Elsevier, 2020) López Vargas, Cristina; Ruiz Benítez, Rocío
    Integrating lean, green and resilient strategies into Supply Chain (SC) decisions is a key success factor for transformation toward sustainability. These strategies are increasingly common in the SC, although their implementation and results are not the same across different SC levels (Tier 1, 2 and 3 suppliers and the focal company). In spite of this, earlier studies have not explored in detail their effects on environmental, economic and social sustainability dimensions nor differentiated between SC levels and therefore implementation strategies overlook the difference between these levels. Accordingly, a novel multilevel analysis of the aerospace manufacturing SC based on Interpretive Structural Modeling (ISM) is carried out. This approach allows exploring the effects of combining lean, green and resilient strategies on specific sustainability performance measures in the aerospace manufacturing SC. The findings reveal differences between SC levels on the effects of lean, green and resilient strategies on the different sustainability dimensions. Additionally, Tiers 2 and 3 show a higher resistance or lower implication in the development of lean, green and resilient strategies than the focal company and Tier 1 companies. Final ISM models become a useful tool for managers to specifically establish coordinated long-term SC sustainability programs for each SC level.

    The lean and resilient management of the supply chain and its impact on performance
    (Elsevier, 2018) Ruiz Benítez, Rocío; López Vargas, Cristina; Real, Juan C.
    The relationship between lean management and resilience in the supply chain, whether negative or positive, is still not clear from the existing literature. This paper aims to investigate the relationship and links between lean and resilient supply chain (SC) practices and their impact on SC performance. To achieve this objective, the aerospace manufacturing sector (AMS) is chosen as the study sector because of the importance of both paradigms. Interpretive Structural Modeling (ISM) approach is used in order to identify linkages among various lean and resilience practices and SC performance metrics through a single systemic framework. ISM is an interactive learning process based on graph theory where experts' knowledge is extracted and converted into a powerful well-structured model. For that purpose, a heterogeneous panel of experts in the AMS was formed, providing a complete view of all SC levels in the sector. The final ISM model revealed that lean SC practices act as drivers for resilient SC practices, since implementing the former in isolation could lead to a more vulnerable SC. The findings also show that lean SC practices lead to a higher performance improvement than resilient SC practices. This is due to the fact that resilient SC practices do not exert influence over all SC performance metrics as it occurs with lean SC practices. In addition, several managerial implications regarding the most convenient practices in terms of the company's objectives are drawn from this study.

    On the Environmental and Social Sustainability of Technological Innovations in Urban Bus Transport: The EU Case
    (mdpi, 2019) López Vargas, Cristina; Ruiz Benítez, Rocío; Vargas-Machuca, Carmen
    Logistics in urban areas are currently suffering a radical transformation due to increasing population concentration and the massive use of cars as the preferred transport mode. These issues have resulted in higher pollution levels in urban environments and traffic congestion, impacting the world globally. Facilitating the use of sustainable transport modes is widely regarded as a necessity to cope with these adverse effects on citizens’ life quality. Hence, some regions, such as the European Union, are encouraging bus transport firms to make their business models more environmentally and socially sustainable. The aim of this research is thus to explore how technological innovations adopted by urban bus companies can improve cities’ sustainability. With this in mind, a combined Importance Performance Analysis (IPA)–Analytic Hierarchy Process (AHP) method was applied. In this way, their environmental and social sustainability effects were separately represented through hierarchical structures. Subsequently, the importance and performance ratings of technological innovations in each sustainability dimension were estimated, and thus two IPA grids were generated. These grids support managers in the establishment of more effective action plans to improve logistics sustainability in cities. The findings also provide guidance to governments on the technological innovations that should be promoted in future urban mobility plans.
