Characterising informal groups of knowledge transfer with social network analysis.

Una de las áreas de mayor relevancia en las dos últimas décadas en el estudio de los activos intangibles ha sido, sin duda, la gestión de las actividades relacionadas con el desarrollo y explotación del conocimiento organizativo. Pero el aprendizaje organizativo es un proceso complejo, en el que intervienen diversos niveles de análisis. Este hecho supone importantes problemas de orden metodológico. El objetivo del artículo es adaptar las técnicas del análisis de redes sociales a la detección de grupos informales y definir los roles de los individuos en dichos grupos a partir de datos relacionales. Se ha aplicado la técnica a una red social formada por un conjunto de profesores que trabajan en la misma escuela de ingeniería.One of the most prominent areas in the two last decades of intangible assets research has been, doubtlessly, the issues related to the creation and exploitation of organizational knowledge. But organizational knowledge is a complex process indeed, where multiple levels of analysis coexist. This fact is the origin of several methodological problems in organizational knowledge research. The aim of this paper is adapting the social network analysis techniques to the task of detecting groups of individuals in organizations, and to asses the role of individuals in these groups. This assessment is undertaken using data representative of the relationships between individuals in organizations. The procedure has been applied to a social network of faculty working in the same college

Equacions estructurals amb lavaan

L'anàlisi d'equacions estructurals és una tècnica per avaluar models amb relacions complexes entre variables (path analysis), amb variables observables i variables latents. Un cas especialment interessant d'aplicació és l'anàlisi factorial confirmatòria, que permet avaluar la validesa de constructe d'escales de mesura. En aquest article es presenta el paquet de R lavaan, que permet avaluar amb facilitat models d'equacions estructurals. Es reporta informació sobre la sintaxi del model, així com de les possibilitats del paquet.Preprin

Recent trends in air transport research: a bibliometric analysis

The aim of this manuscript is to detect recent trends in air transport research through a bibliometric analysis. We have retrieved all articles published between 2013 and 2022 in the Q1 of the Transportation ranking of the Social Sciences Citation Index published in the Journal Citations Reports (Q1-T), and in the Journal of Air Transport Management. Both samples share the topics Industry Analysis, Air Traffic Management and COVID-19 and Air Transport. The specific topics of Q1-T sample are High Speed Rail and Air Transport, Environmental Impact of Air Transport and UAV and Urban Air Mobility. We have also found that materials of Q1-T are mainly written from the regulator perspective, and JATM materials from the perspective of airport and airline managers.The aim of this manuscript is to detect recent trends in air transport research through a bibliometric analysis.

Among these records, we retained for the analysis the articles related with air transport. Analysing the author keywords of articles and retaining the Top 10 cited articles in each of the samples, we have identified six research topics for each of the samples. Both samples share the topics Industry Analysis, Air Traffic Management and COVID-19 and Air Transport. The specific topics of Q1-T sample are High Speed Rail and Air Transport, Environmental Impact of Air Transport and UAV and Urban Air Mobility. We have also found that materials of Q1-T are mainly written from the regulator perspective, and JATM materials from the perspective of airport and airline managers. We believe that this results are useful for administrators evaluating air transport academics, air transport academics themselves looking for new avenues of research and stakeholders of the air transport industry interested in evidence-based decision making.Preprin

Core and critical cities of global region airport networks

Air transport is one of the key infrastructures of today’s global economy. Connections between airports define airport networks, where nodes are cities served by airports, connected by edges if there is at least one direct flight connecting them. The aims of this research are to relate structural properties of airport networks which explain how these networks respond to isolation of critical nodes, and to gain insight into relevant socio-economic factors that influence the development of airport networks. We split the world airport network (WAN) into seven global region airport networks (GRANs), using the divisions established by OAG database. We gather information about structural properties of each GRAN determining core cities through k-core decomposition, and critical cities through robustness analysis. We find that differences of robustness across GRANs can be explained by the fraction of core cities relative to total cities. Furthermore, analysis of multilevel structure reveal relevant differences between GRANs, rooted on geographical and socio-economic factors, and give insight about how network robustness in airport networks can be enhancedPeer ReviewedPostprint (author's final draft

Efficient multi-unit procurement mechanism with supply disruption risk

In this paper, we study the multi-attribute multi-unit procurement mechanism design problem facing a set of potential suppliers who suffer from disruption risks. Each supplier's production cost depends on its disruption probability, and both are private information. We propose a Vickery-Clark-Groves auction with disruption risk (VCG-DR) for this problem and show that the mechanism is incentive-compatible, individual-rational and social efficient. Moreover, we compare the performance of the proposed mechanism and the popular single-attribute multi-unit forward auction (SA-MFV) with reserved attribute by numerical experiments. The results show that VCG-DR outperforms SA-MFV in both social efficiency and optimality.Peer ReviewedPostprint (author's final draft
