This special theme issue of Big Data & Society presents leading-edge, interdisciplinary research that focuses on examining how health-related information is circulating on social media. In particular, we are focusing on how computational and Big Data approaches can help to provide a better understanding of the ongoing COVID-19 infodemic and to develop effective strategies to combat it.

A review of the achievements of Fr. Busa over the course of his 60 years of work in the area of computational linguistics: internal hypertexts, the systematization of allographs, lemmatization, homographs and typologies; the lexical system; the laws of economy for graphemes, for semantic typology, for heterogeneity among terms, and of the two lexical hemispheres. Finally, the project of disciplined languages is mentioned, a response to the linguistic challenge resulting from informational globalization.

Nietzsche, para Heidegger, não teria levado a termo a desvalorização dos valores considerados até então válidos. A transvalorização, ao invés de garantir a renovação da condição existencial do homem, antepõe, à tematização do ser, o nada mudado em vontade e representação. O querido, contra os pressupostos da vontade de poder, se esclerosa na tangibilidade das coisas sem a possibilidade do além por meio do qual Nietzsche pensava superar o niilismo. A transvaloração conserva em tal aspecto a lógica dos velhos valores (...) por conta de uma vontade fixada na presumida concretude da enticidade. Nietzsche é o paradigma de uma metafísica que pensa o ser dentro da não verdade ou de uma verdade transformada na relação sujeitoobjeto. Por tudo isso, a transvaloração, longe de fundar uma nova posição de valores, é adscrivível à nadificação do sujeito, constantemente correlacionado ao objeto. O super-homem não é senão uma super-objetividade que se ilude de reviver na mais completa plenitude, com base no platonismo invertido. Contra Nietzsche, os niilismos se assemelham por não poderem não pensar o ser ao modo de um ser-aí: uma paranoica divinização da corporeidade dentro da realidade mundana. Palavras-chave: Nietzsche. Heidegger. Kant. Transvaloração. Metafísica. Niilismo. (shrink)

PurposeThe purpose of this study is to illustrate how the adoption of new enterprise resource planning systems affects sensemaking in the process of Organizational Identity integration after a Merger and Acquisition.Design/methodology/approachWithin a wider case study about an acquisition in chemical/pharmaceutical industry, the paper describes the effects of SAP adoption and implementation on the organizational identity. This methodology, based on semi‐structured interviews to project leaders and to team members, has allowed a deep comprehension of the context, even if results cannot provide (...) statistical evidence of relationships.FindingsUsing the Swanson and Ramiller's approach to innovation, the paper argues that ERP adoption and implementation support sensemaking process if innovation takes place with mindfulness and because, in that case, people interact on symbolic meanings sharing retrospective knowledge and cognitive causal maps. After an M&A there are conditions for a mindful innovation with IT and therefore innovating with IT can be an effective way to enforce sensemaking process and, as a consequence, to influence the Organizational Identity evolution. In a constructionist approach, the evolution of organizational identity requires a social negotiation among members where sensemaking has a primary role. So, the integration process following acquisitions can be facilitated by adopting, implementing and assimilating common IT solutions with mindfulness.Research limitations/implicationsThe first limitation of this study is referred to timing. The author entered into the company within a year after the acquisition and went out at the beginning of SAP assimilation phase. Therefore, some perceptions could still evolve in different ways. The second limitation depends on the fact that the author analyzed a single case. By focusing on one case of acquisition – an acquisition that gives value to acquired company – the author might be limiting the transferability of the findings.Practical implicationsThese results can be useful for both scholars and practitioners. Managers who face organizational change can consider the adoption and implementation of ERP as an opportunity to influence the evolution of Organizational Identity according to strategic priorities.Originality/valueThe value of this study is in its approach that links a strategic level with a social level. This link is realized not using the ERP as an artefact but using the process of its adoption and implementation. (shrink)

The tensorial relativistic quantum mechanics in (1+1) dimensions is considered. Its kinematical and dynamical features are reviewed as well as the problem of finding the Dirac spinor for given finite multivectors. For stationary states, the dynamical tensorial equations, equivalent to the Dirac equation, are solved for a free particle, for a particle inside a box, and for a particle in a step potential.

Este trabajo analiza el significado metafísico y metaliterario de la estética de la repetición en la obra narrativa de Borges. Los espejos, las sombras, los fantasmas, los dobles y todas las otras estrategias de repetición de la realidad eran, para él, alegorías de la escritura. Borges utilizó estos mecanismos como “yescas” narrativas —en el sentido barthesiano de la palabra—, para presentar tanto la compleja noción de “los diversos tiempos del tiempo” como su idea de la literatura como “ficción”.

War and the future of the international order. For the members of the Bush administration, the clash between the USA and the UN over war in Iraq would appear to have weakened or irrevocably discredited the UN. Luigi Ferrajoli argues that, on the contrary, the conflict actually signals a revival of the UN, after a period characterised by its servile submission to imperialism. Thanks to the current international situation, and secure in the knowledge that world opinion supports its stance, (...) the UN, by its refusal to countenance the invasion, has for the first time demonstrated its capacity to comply with the pacifist stipulations of the United Nations, giving them the force of international law. While the author does not draw conclusions which are entirely optimistic, he does however consider that the outcome of the invasion has modified the relative strength of the two opposing parties : the US and the movement of resistance which has gained expression worldwide.

The present study aimed to verify the quarantine’s effects during a serious viral outbreak on the cardiovascular and performance associated with the Yo-Yo test in a sample of professional soccer players. 20 high-level soccer players participated in this study. The intermittent Yo-Yo test was performed pre- and post- COVID-19 quarantine in a random order. During each test, the soccer players’ running performance outcomes were monitored using a portable 5-Hz GPS with a 100 Hz accelerometer and a paired t-test was conducted (...) at a p-value of ≤ 0.05. The main results demonstrated significant differences between pre- versus post-COVID-19 quarantine in the following variables: relative distance, maximal speed, acceleration, deceleration, sprints > 19 km/h [0.8 % >0.5 %], and in high intensity running distance [16.48 m > 0.827 m]. We concluded that COVID-19-related restrictions and quarantine COVID-19 demonstrated adverse effects on professional soccer players’ Yo-Yo tests performance. (shrink)
