Physical Activity Levels and Related Energy Expenditure during COVID-19 Quarantine among the Sicilian Active Population: A Cross-Sectional Online Sur…
2020
Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Italian government has adopted containment measures to control the virus’s spread, including limitations to the practice of physical activity (PA). The aim of this study was to estimate the levels of PA, expressed as energy expenditure (MET–minute/week), among the physically active Sicilian population before and during the last seven days of the COVID-19 quarantine. Furthermore, the relation between this parameter and specific demographic and anthropometric variables was analyzed. Methods: 802 Sicilian physically active participants (mean age: 32.27 ± 12.81 years; BMI: 23.44 ± 3.33 kg/m2) were included in the study and…
Introduction to Special Issue: Brand Equity, Satisfaction, and Word of Mouth
2021
The COVID-19 pandemic has generated an incredible change in the global economy that will likely have long-term consequences on consumer behavior, markets, business models, market regulation, and public policies, among others [1,2]. We are only at the beginning of seeing these effects, and this new scenario offers opportunities to articulate research in the area of marketing aligned with the urgency of recovering customer trust and reactivating sales [3]. The five contributions presented in this Special Issue, “Brand Equity, Satisfaction, and Word of Mouth”, aim at being incorporated into the dynamics of methodological and thematic innovation in marketing, in reply to some of the research pr…
Online mathematics teaching and learning during the COVID-19 pandemic: The perspective of lecturers and students
2021
The global spread of the novel coronavirus, Covid-19, reached Norway at the end of February 2020. MatRIC, Centre for Research, Innovation and Coordination of Mathematics Teaching conducted a national survey in Norwegian higher education institutions (HEIs) during June-July 2020 to explore lecturers’ and students’ experiences of online mathematics teaching and learning and to enable sharing of solutions to the challenges encountered. One hundred and twenty-seven students and eighteen lecturers participated in this survey. In this presentation, we will share some of the findings of the survey in relation to the following two themes: challenges of learning and teaching mathematics online, and …
Research on Unrealistic Optimism among HoReCa Workers as a Possible Future Hotspot of Infections
2021
As we are facing a new surge of the highly infectious delta variant of COVID-19, there is an urgent need for research to reduce the harm before this next wave hits. In the present paper, we present data that is alarming. We have found that HoReCa (hotels, restaurants, and catering services) workers, who are highly exposed to many new social interactions in close contact, present an unrealistic optimism (UO) bias: they perceive themselves as less at risk to this virus in comparison to others. From the literature, we already know that individuals holding this view are less involved in preventive actions and present more risky behaviors. In the face of the delta variant, this leads to the conc…
(Un)sustainable creativity? Different manager-employee perspectives in the finnish technology sector
2020
The importance of creativity for working life and in organizations has increased in recent years. At the same time, the theme of sustainability has been intensely debated in research, society, and organizations. Together, creativity and sustainability have sometimes been described as a contradictory phenomenon: they are described in ways that place them in opposition to each other. To better understand creativity and sustainability and their differences from the perspective of people in different positions, we take advantage of a sociocultural approach in which we do not focus only on creative individuals but also on the impact of creativity on both organizational stakeholders and society a…
Contextual and local determinants associated with the achievement of goals in the endodontics specialty in Brazilian dental speciality centres: A mul…
2021
To assess which factors were associated with the achievement of endodontic goals.Cross-sectional study using secondary data from the second cycle of the Program for the Improvement of Access and Quality in the dental speciality centres-in Portuguese PMAQ-CEO. The independent variables extracted from this database were related to dental speciality centres (CEO in Portuguese). In addition, variables referring to the CEO host city were incorporated into the model. The outcome variable was the number of endodontic goals achieved calculated from the production of the CEO available in the Ambulatory Health Information System in 2018. Descriptive analyses and multilevel Poisson regression were per…
The role of dental pain and psychosocial factors on the relationship between dental caries and oral health‑related quality of life in children
2022
Abstract Background To examine the role of dental pain, sense of coherence (SOC) and social support on the relationship between dental caries and oral health-related quality of life (OHRQoL) in children aged 12 years. Methods A cross-sectional study involving 400 schoolchildren selected from public schools in a socioeconomically disadvantaged region in the city of Manaus, Brazil was carried out. The predictors of OHRQoL were selected according to the Wilson and Cleary theoretical model, including number of decayed teeth and its clinical consequence (component D of the DMFT index and PUFA/pufa index), dental pain (symptom status), and SOC and social support (individual and environmental char…
ICTV Virus Taxonomy Profile: Cystoviridae
2017
The family Cystoviridae includes enveloped viruses with a tri-segmented dsRNA genome and a double-layered protein capsid. The innermost protein shell is a polymerase complex responsible for genome packaging, replication and transcription. Cystoviruses infect Gram-negative bacteria, primarily plant-pathogenic Pseudomonas syringae strains. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Cystoviridae, which is available at http://www.ictv.global/report/cystoviridae.
New enveloped dsRNA phage from freshwater habitat.
2015
Cystoviridae is a family of bacteriophages with a tri-segmented dsRNA genome enclosed in a tri-layered virion structure. Here, we present a new putative member of the Cystoviridae family, bacteriophage ϕNN. ϕNN was isolated from a Finnish lake in contrast to the previously identified cystoviruses, which originate from various legume samples collected in the USA. The nucleotide sequence of the virus reveals a strong genetic similarity (~80 % for the L-segments, ~55 % for the M-segments and ~84 % for the S-segments) to Pseudomonas phage ϕ6, the type member of the virus family. However, the relationship between ϕNN and other cystoviruses is more distant. In general, proteins located in the int…
Permeability changes of integrin-containing multivesicular structures triggered by picornavirus entry.
2014
Cellular uptake of clustered α2β1-integrin induces the formation of membrane compartments that subsequently mature into a multivesicular body (MVB). Enhanced internalization mediated by clustered integrins was observed upon infection by the picornavirus echovirus 1 (EVI). We elucidated the structural features of virus-induced MVBs (vMVBs) in comparison to antibody-induced control MVBs (mock infection) by means of high-pressure cryo fixation of cells followed by immuno electron tomography during early entry of the virus. Three-dimensional tomograms revealed a marked increase in the size and complexity of these vMVBs and the intraluminal vesicles (ILVs) at 2 and 3.5 hours post infection (p.i.…
