    Enablers of post-COVID-19 customer demand resilience: evidence for fast-fashion MSMEs
    (Emerald Publishing Limited, 2023-07-06) Fares, Naila; Lloret Mauri, Jaime; Kumar. Vikas; Frederico, Guilherme F.; Kumar, Anil; Garza-Reyes, Jose Arturo; Dpto. de Comunicaciones; Escuela Politécnica Superior de Gandia; Instituto de Investigación para la Gestión Integrada de Zonas Costeras
    [EN] Purpose This study aims to analyse the resilience of customer demand management post-coronavirus disease 2019, using fast fashion as an example. The paper provides insights for potential applications to micro-, small and medium enterprises (MSMEs). Design/methodology/approach Based on the qualitative analysis and an integrated Plan-Do-Check-Act (PDCA)-decision making trial and evaluation laboratory (DEMATEL)-fuzzy technique for order of preference by similarity to the ideal solution (TOPSIS) methodology of fuzzy multi-criteria decision-making, we explored and prioritised the enablers of resilience management for fast-fashion MSMEs. Findings The results reveal that the highest priority enabler is maintaining customer loyalty. Other enablers are associated with e-commerce endorsement, a customer-focussed assortment of items and flexible store operations. Research limitations/implications The study findings will enable fast-fashion MSMEs to develop effective actions and priorities in operations efforts to promote post-pandemic recovery. Originality/value Despite the importance of the resilience project and the changing fast-fashion customer patterns, only a handful of studies have explored how resilience can be managed in this field. Thus, the findings can contribute to closing this gap in the context of operations resilience research as well as MSME operations.

    Resilient Roadmap to Minimise the Impact of COVID-19 in the Spanish Enterprises
    (Elsevier, 2022-10) Sanchis Gisbert, Raquel; Cruz-Valdivieso, Tania; Marcucci, Giulio; Poler Escoto, Raúl; Dpto. de Organización de Empresas; Centro de Investigación en Gestión e Ingeniería de Producción; Escuela Politécnica Superior de Alcoy; COMISION DE LAS COMUNIDADES EUROPEA
    [EN] If something has failed in the management of COVID-19 crisis, this has been the lack of resilience to anticipate, adapt and recover from this event. This paper analyses the impact of COVID-19 in different sectors in Spain, highlighting which ones were more negatively affected by the pandemic after the first COVID-19 wave and which ones created growth and employment during the recovery phase. In this sense, the most negative impacted sectors were culture, tourism and retail while tobacco, pharmaceuticals computer, electronic and optical products sectors pushed the Spanish economy towards recovery. Moreover, the impact of COVID-19 in different aspects such as employment, workers¿ health, reputation, productivity, among others was also studied. The results reveal that firms invested a lot of time in organising and restructuring work planning to adapt to the new constraints. Finally, based on the findings about the most impacted sectors and the most negatively affected aspects, a set of dimensions and policies are proposed in a roadmap to support the improvement of enterprise resilience capacity to face up to crisis situations such as the one caused by COVID-19.

    How has the announcement of the Covid-19 pandemic and vaccine impacted the market?
    (Taylor & Francis, 2022-12-31) Alcaide González, María Ángeles; Guadalajara Olmeda, María Natividad; Poza Plaza, Elena de la; Facultad de Administración y Dirección de Empresas; Dpto. de Economía y Ciencias Sociales; Centro de Investigación de Ingeniería Económica
    [EN] As COVID-19 has hit the whole world hard, finding a vaccine that alleviates its effects has been one of the most anticipated events in 2020. This work studies the impact of the two main events in 2020 on companies' stock exchange activities: announcing COVID-19 as a world pandemic and announcing the first coronavirus vaccine. This study was carried out by an event study methodology using Nasdaq-100 data. Ordinary Least Squares (OLS) and quantile (Q) regression were used to obtain the returns expected from shares and to assess if there were any significant differences in the reactions of the analysed sectors on the market in each event window. The obtained empirical results show different share performances by sectors. Specifically, only those shares from the technology sector positively and significantly reacted to the first announcement. However, the opposite can be stated of the second event insofar as confidence in financial markets recovered to a greater extent in the sectors hardest hit by the first announcement. These conclusions are meaningful for companies, investors and governments to make better decisions or to adopt new policies.

    El comercio electrónico antes, durante y después del Covid-19. Aplicación al sector de la moda
    (Universitat Politècnica de València, 2023-09-18) Beneyto Navarro, Javier; Grau Gadea, Gonzalo Francisco; Dpto. de Organización de Empresas; Facultad de Administración y Dirección de Empresas
    [ES] El comercio electrónico o e-commerce es un mecanismo de compra-venta con unas características particulares que lo diferencian del comercio tradicional. Originalmente, este concepto se atribuía a la realización de transacciones mediante medios electrónicos. Sin embargo, con la llegada de Internet y del World Wide Web, a mediados de la década de 1990 comenzó a utilizarse la palabra e-commerce para referirse a la venta de bienes y servicios a través de Internet usando como método de pago tarjetas de crédito, pago móvil o diversas plataformas de pago. El comercio electrónico ha ido creciendo hasta ahora de manera extraordinaria, debido al avance de las nuevas tecnologías y de Internet. Además, otros factores externos han incidido en el crecimiento del número de transacciones en plataformas e-commerce. En este trabajo observaremos la influencia que ha tenido el coronavirus en el comercio electrónico, estudiando la importancia que ha adquirido después de la crisis de la pandemia. Reduciremos el ámbito de estudio al sector de la moda en España.

    Development of an Artificial Intelligence model for COVID-19 detection based on electrocardiogram features
    (Universitat Politècnica de València, 2023-09-18) Moltó Miró, Juan; Sáez Silvestre, Carlos; Dpto. de Física Aplicada; Instituto Universitario de Tecnologías de la Información y Comunicaciones; Escuela Técnica Superior de Ingeniería Industrial
    [ES] Los objetivos de este proyecto son dos. En primer lugar, identificar características morfológicas clave en las señales de electrocardiograma (ECG) de 12 derivaciones que puedan ayudar a identificar a los pacientes infectados por la enfermedad SARS-CoV-2 con mayor riesgo de mortalidad. En segundo lugar, desarrollar un modelo de aprendizaje automático que las utilice para la detección de la enfermedad por coronavirus 2019 (COVID-19). El desarrollo de este trabajo implica extraer características que representen las principales estructuras del ECG, como la onda P, el complejo QRS y la onda T. Para ello, se utilizan cajas de herramientas de libre acceso en MATLAB. Además, la limpieza, el preprocesamiento, la selección y el entrenamiento del modelo se llevan a cabo con Python. Utilizamos señales cortas de ECG de 12 derivaciones obtenidas de pacientes con COVID-19 en un hospital de la ciudad italiana de Cremona (Ospedale di Cremona). El modelo desarrollado permitirá la detección precoz del virus COVID-19 utilizando el procedimiento clínico no invasivo del ECG.
