ABSTRACT

Due to the pandemic, it was necessary to switch to distance learning. As such, the present investigation has the aim of perceiving the students’ satisfaction of the quality of distance learning, and their reasons. 314 online surveys were carried out, aimed at tourism students at different levels of education. The data allows us to interpret and evaluate the methodologies and resources used and to readapt them in the face of the identified weaknesses. Students’ opinions on online classes tend to be more positive than negative. However, only 19% consider that they learn through technological means. There are benefits of online classes, comfort, not being exposed to the virus, no commute, however, there are negatives as well, the lack of contact with teachers and colleagues, work overload, ease of copying, massive classes, ease of distraction, and invasion of privacy by forcing sound and connected cameras. When analyzing the technologies used, there is a trend towards the use of PowerPoint, Kahoot, Padlet, Google forms, Quizizz, and Mentimeter. We believe that in the future, tourism teachers should be inquired, regarding the methodologies used and difficulties experienced. © 2022, Journal of Tourism & Development. All rights reserved.

ABSTRACT

BACKGROUND: The absence of systematic surveillance for SARS-CoV-2 has curtailed accurate appraisal of transmission intensity. Our objective was to perform case detection of an entire rural community to quantify SARS-CoV-2 transmission using PCR and antibody testing. METHODS: We conducted a cross-sectional survey of the prevalence and cumulative incidence of SARS-CoV-2 infection in the rural town of Bolinas, California (population 1,620), four weeks following shelter-in-place orders. Residents and county essential workers were tested between April 20th-24th, 2020. Prevalence by PCR and seroprevalence combining data from two forms of antibody testing were performed in parallel (Abbott ARCHITECT IgG to nucleocapsid protein and in-house IgG ELISA to the receptor binding domain). RESULTS: Of 1,891 participants, 1,312 were confirmed Bolinas residents (>80% community ascertainment). Zero participants were PCR positive. Assuming 80% sensitivity, it would have been unlikely to observe these results (p<0.05) if there were >3 active infections in the community. Based on antibody results, estimated prevalence of prior infection was 0.16% (95% CrI: 0.02%, 0.46%). Seroprevalence estimates using only one of the two tests would have been higher, with greater uncertainty. The positive predictive value (PPV) of a positive result on both tests was 99.11% (95% CrI: 95.75%, 99.94%), compared to PPV 44.19%-63.32% (95% CrI range 3.25%-98.64%) if only one test was utilized. CONCLUSIONS: Four weeks following shelter-in-place, active and prior SARS-CoV-2 infection in a rural Northern California community was extremely rare. In this low prevalence setting, use of two antibody tests increased the PPV and precision of seroprevalence estimates.

ABSTRACT

This study aimed to assess perceptions on the graphical informational materials designed to help in the fght against COVID-19 in Portugal and Brazil. We assessed the perceptions using an online survey incorporating the AttrakDiff2TM questionnaire. The results show that the perception of risk with relation to the COVID-19 pandemic is high among the respondents, and that they believe that they will have mild symptoms if infected by the virus. The results also show that the materials available in these countries were poorly designed and not effective in promoting adequate behaviour change. These fndings can contribute to future design projects whose aim is to design risk communication materials to inform and guide people facing health crisis situations. © 2021 John Benjamins Publishing Company.

ABSTRACT

Amidst the COVID-19, the use of technology in the learning environment was no longer a matter of choice. Forced by circumstance, educators had to adapt in order to see the academic year through. While for some, already used to an online modality, it was business as always, for others was the start of a journey through unfamiliar territory. This study inserts itself in such context. It presents and discusses results gathered through an online questionnaire about the perceptions and personal experiences of design educators in Higher Education (HE) caught in this move from in-class face-to-face onto online teaching. Objectively, it portrays how this shift impacted their ability to teach, the compromises made or alternatives sought, and views towards a more technologically enabled future in HE. From a more extensive reliance on Learning Management Systems (LMS), changes in the learning environment, and perspectives of near-future uses of Virtual Reality (VR) in distance education, this study covers uses of technology but also the identification of pain points influencing the overall experience, as well as positive perceptions and significant changes made to the learning environment. © 2020 Universidade do Vale do Rio dos Sinos.

ABSTRACT

BACKGROUND: Stroke can lead to varying degrees of oropharyngeal dysphagia, respiratory muscle dysfunction and even increase medical complications such as aspiration, malnutrition and death. Recent studies suggest that inspiratory and expiratory respiratory muscle training (IEMT) can improve swallowing efficacy and may reduce aspiration events. The main purpose of this study is to examine whether an 8-week IEMT programme can improve respiratory muscle strength and swallow dysfunction severity in subacute stroke patients with dysphagia. METHODS: Retornus-2 is a two-arm, prospectively registered, randomized controlled study with blinded assessors and the participation of fifty individuals who have suffered a stroke. The intervention group undergoes IEMT training consisting of 5 sets of 10 repetitions, three times a day for 8 weeks. Training loads increase weekly. The control group undergoes a sham-IEMT protocol. The primary outcome examines the efficacy of the IEMT protocol to increase respiratory muscle strength and reduce dysphagia severity. The secondary outcome assesses the longitudinal impact of dysphagia on body composition and nutritional assessment over a 6-month follow-up. DISCUSSION: IEMT induces an improvement in respiratory muscle strength and might be associated with relevant benefits in dysphagia patterns, as well as a reduction in the number of aspiration events confirmed by videofluoroscopy or fiberoptic endoscopic evaluation of swallowing. The description of the impact of swallowing impairment on nutritional status will help develop new strategies to face this known side-effect. TRIAL REGISTRATION: Clinicaltrials.gov NCT03021252.

ABSTRACT

Serosurveillance provides a unique opportunity to quantify the proportion of the population that has been exposed to pathogens. Here, we developed and piloted Serosurveillance for Continuous, ActionabLe Epidemiologic Intelligence of Transmission (SCALE-IT), a platform through which we systematically tested remnant samples from routine blood draws in two major hospital networks in San Francisco for SARS-CoV-2 antibodies during the early months of the pandemic. Importantly, SCALE-IT allows for algorithmic sample selection and rich data on covariates by leveraging electronic medical record data. We estimated overall seroprevalence at 4.2%, corresponding to a case ascertainment rate of only 4.9%, and identified important heterogeneities by neighborhood, homelessness status, and race/ethnicity. Neighborhood seroprevalence estimates from SCALE-IT were comparable to local community-based surveys, while providing results encompassing the entire city that have been previously unavailable. Leveraging this hybrid serosurveillance approach has strong potential for application beyond this local context and for diseases other than SARS-CoV-2.
