This study examines how confinement measures established during the COVID-19 pandemic crisis affected the emotions of the population. For this purpose, public sentiment on social media and digital ecosystems in Spain is analyzed. We identified affective tones towards media and citizens published on social media focusing on six basic emotions: anger, fear, joy, sadness, disgust and uncertainty. The main contribution of this work is the evidence of contagious sentiments and, consequently, the possibility of using this new dimension of social media as a form of a “collective therapy”. This paper contributes to understanding the impact of confinement measures in a pandemic from the point of view of emotional health. This analysis provides a set of practical implications that can guide conceptual and empirical work in health crisis management with an alternative approach, especially useful for decision-making processes facing emergency responses and health crises, even in an unprecedented global health crisis such as the traumatic events caused by the COVID-19 disease.

The purchasing process is not an isolated or unique fact, but a process that contains distinct phases. One of these phases is the evaluation of alternatives, in which the consumer compares the benefits that will be obtained from each brand, product or service, depending on a set of characteristics or criteria. Knowing these criteria and their importance is essential to companies for the supply and development of their products. Commonly this process is developed through multiple criteria decision-making methods, where experts, using surveys and their own experience, ascertain the consumers' purchasing criteria, as well as the importance of them. But this process to determine the importance of the criteria is not simple, as the thought, attitude and learning that direct purchases contain relations that consumers are not able to express explicitly; and secondly because the current information society in which we live causes consumers to receive large volumes of information at all times, causing perception changes regularly. This causes growing discrepancies between the rankings offered by experts and the actual purchase ranking of products and services. In this paper we propose a model to estimate the importance of the criteria and alternatives driving purchases making use of the information expressed by consumers in digital ecosystems. This model takes a set of comparable alternatives defined by the client and valuation criteria defined by experts, and by making use of the assessments that consumers make in digital ecosystems, determines the synergies implicit between the criteria and calculates their weight. Lastly, making use of the Choquet integral, the model aggregates the information and determines International Symposium on the Analytic Hierarchy Process

Various management models have been proposed for intangible business assets in this new digital era. However, these models do not consider the relationships between intangible assets in business management, or their effect. This work has two main objectives: first, to show the effect of intangi-ble assets as expressed in digital media related to energy brands; second, to demonstrate the rela-tionships between the emotions, experiences and attitudes of the audiences. To do so, a novel model of intangibles is proposed and applied to the energy sector using IBEX 35 data. In this sce-nario, we determine that users' experiences extracted from digital environments have significant relationships with one of the most important intangibles in the energy business, namely emotion.Keywords: Emotion, digital influencers, intangibles management, reputational intelligence, social media. ResumoVários modelos de gestão foram propostos para ativos de negócios intangíveis nesta nova era digi-tal. No entanto, esses modelos não consideram as relações entre ativos intangíveis na gestão ou os seus efeitos. Este estudo tem dois objetivos principais: primeiro, mostrar o efeito dos ativos intan-gíveis expressos nos meios digitais relacionados com as marcas associadas ao setor económico da energia; segundo, demonstrar as relações entre as emoções, experiências e atitudes do público. Para esse efeito, é proposto um novo modelo de gestão de intangíveis aplicado ao setor de energia utili-zando dados do IBEX 35. Nesse cenário, concluímos que as experiências dos utilizadores extraídas de ambientes digitais têm relacionamentos significativos com um dos intangíveis mais importantes no negócio de energia, ou seja, a emoção.Palavras-chave: Emoção, gestão de intangíveis, influenciadores digitais, reputação inteligente, social media.
