Diffusion modeling of COVID-19 under lockdown
2021
Viral immune evasion by sequence variation is a significant barrier to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine design and coronavirus disease-2019 diffusion under lockdown are unpredictable with subsequent waves. Our group has developed a computational model rooted in physics to address this challenge, aiming to predict the fitness landscape of SARS-CoV-2 diffusion using a variant of the bidimensional Ising model (2DIMV) connected seasonally. The 2DIMV works in a closed system composed of limited interaction subjects and conditioned by only temperature changes. Markov chain Monte Carlo method shows that an increase in temperature implicates reduced virus diffusi…
Anam-Net: Anamorphic Depth Embedding-Based Lightweight CNN for Segmentation of Anomalies in COVID-19 Chest CT Images.
2021
Chest computed tomography (CT) imaging has become indispensable for staging and managing coronavirus disease 2019 (COVID-19), and current evaluation of anomalies/abnormalities associated with COVID-19 has been performed majorly by the visual score. The development of automated methods for quantifying COVID-19 abnormalities in these CT images is invaluable to clinicians. The hallmark of COVID-19 in chest CT images is the presence of ground-glass opacities in the lung region, which are tedious to segment manually. We propose anamorphic depth embedding-based lightweight CNN, called Anam-Net, to segment anomalies in COVID-19 chest CT images. The proposed Anam-Net has 7.8 times fewer parameters …
A bioweapon or a hoax? The link between distinct conspiracy beliefs about the Coronavirus disease (COVID-19) outbreak and pandemic behavior
2020
During the coronavirus disease pandemic rising in 2020, governments and nongovernmental organizations across the globe have taken great efforts to curb the infection rate by promoting or legally prescribing behavior that can reduce the spread of the virus. At the same time, this pandemic has given rise to speculations and conspiracy theories. Conspiracy worldviews have been connected to refusal to trust science, the biomedical model of disease, and legal means of political engagement in previous research. In three studies from the United States ( N = 220; N = 288) and the UK ( N = 298), we went beyond this focus on a general conspiracy worldview and tested the idea that different forms of …
Resilience and Parental Burnout Among Finnish Parents During the COVID-19 Pandemic: Variable and Person-Oriented Approaches.
2021
During the coronavirus disease 2019 (COVID-19) crisis, different personality characteristics may have influenced parental well-being in different ways. In the present study, we combined variable and person-oriented approaches and examined relationships between resilience, parental burnout, and perfectionism during the lockdown. We first used structural equation modeling to assess the paths between variables. We then used latent profile analysis to examine different profiles of parents based on resilience, perfectionism, and symptoms of parental burnout. Finally, we examined how these profiles differ in terms of relevant background variables. The results showed that resilience predicted par…
Los cambios en la gestión del régimen de clases pasivas: ¿un ataque a las singularidades de los regímenes especiales de funcionarios?
2020
El objetivo de este trabajo es analizar los cambios en la gestión del régimen de clases pasivas aprobados durante el 2020 dentro de la legislación de urgencia suscrita durante el estado de alarma. El traspaso de la gestión al Instituto Nacional de Seguridad Social plantea tres cuestiones: primero, si el traspaso es técnicamente adecuado; segundo, por qué se ha efectuado en un real decreto ley de medidas para paliar los efectos económicos del COVID-19 una medida que afecta a la gestión de las pensiones de funcionarios, y, tercero, qué puede suponer este cambio de gestión para las especialidades contenidas en este régimen especial. The objective of this paper is to analyze the changes in the …
Presentación del debate: Impactos sociales de COVID-19: un nuevo reto para la sociología
2020
La pandemia COVID-19 ha convulsionado el mundo, y la sociología debe ser protagonista en la lectura e interpretación de estos movimientos, contribuyendo, además, a la construcción de propuestas a los problemas que se vislumbran. Más allá de un fenómeno epidemiológico y sanitario, la pandemia es también un fenómeno sociológico, y las medidas que se propongan también han de serlo. Esto supone que no solo hay que indagar el agente causante de la pandemia de naturaleza biológica, sino también los determinantes sociales de la salud, y los efectos de las medidas adoptadas en la vida social.
Does the platform matter? Social media and COVID-19 conspiracy theory beliefs in 17 countries
2021
While the role of social media in the spread of conspiracy theories has received much attention, a key deficit in previous research is the lack of distinction between different types of platforms. This study places the role of social media affordances in facilitating the spread of conspiracy beliefs at the center of its enquiry. We examine the relationship between platform use and conspiracy theory beliefs related to the COVID-19 pandemic. Relying on the concept of technological affordances, we theorize that variation across key features make some platforms more fertile places for conspiracy beliefs than others. Using data from a crossnational dataset based on a two-wave online survey cond…
Comparing technology acceptance of K‐12 teachers with and without prior experience of learning management systems : A Covid‐19 pandemic study
2021
Covid-19 pandemic has caused a massive transformation in K-12 settings towards online education. It is important to explore the factors that facilitate online teaching technology adoption of teachers during the pandemic. The aim of this study was to compare Learning Management System (LMS) acceptance of Finnish K-12 teachers who have been using a specific LMS as part of their regular teaching before the Covid-19 pandemic (experienced group) and teachers who started using it for emergency remote teaching during the pandemic (inexperienced group). Based on the Unified Theory of Acceptance and Use of Technology framework, a self-report questionnaire was administered to 196 teachers (nexperienc…
