A new occupancy index model based on artificial vision for enhancing beach management

This study proposes a new method to more effectively plan the use of beaches by combining indices and artificial vision systems. The Overcrowding Index (Iocr) measures the number of people on the beach in relation to its surface area, while the Distancing Index (Idis) evaluates the spatial distribution and distance between beachgoers. Both indices are combined to generate an overall index called the Occupancy Index (Iocu). The proposed methodology uses cameras and computer vision algorithms such as YOLOX and ByteTrack to automate the counting of people and measure distances. This allows for continuous monitoring of the quantity (carrying capacity and density) and distribution of beachgoers (degree of social distancing), as well as a functional prototype in which the indices are calculated in real time. It was observed that as density increased, Iocr showed an inverse trend, being close to 0 when approaching maximum density. The calculation of the distance between groups validated that, even with medium densities, close to the shoreline, the reference distance of 2 m was not accomplished, obtaining a very low Idis (0.18). The resulting Iocu was 0.31, validating the appropriate integration of both indices. Overall, the system's effectiveness for accurately monitoring the number of users and their distribution, and calculating the defined indices for beach management, is demonstrated. The proposed approach provides a valuable tool, allowing a more efficient management of beaches according to their actual occupancy and user distribution.

Explaining immigrants’ social distance towards natives: A multilevel mediation approach across immigrant groups in Germany

What factors underlie immigrants' social distance towards natives? Previous studies found that immigrants who perceive themselves as rejected by natives express more negative intergroup attitudes towards natives. Another line of research found that contingent on their origin country, immigrants face different degrees of social distance from natives. In this study, we employ an intergroup threat approach to integrate these separate research strands. The theoretical model we develop predicts that immigrants from groups that receive greater social distance from natives will perceive more personal discrimination, which, as a mediating mechanism, will be associated with greater social distance towards natives. Empirically, we draw on a cross-sectional probability sample of 1789 immigrants from 38 origin countries living in Germany (i.e., a comparative origin design). The results of multilevel mediation analyses prove consistent with our theoretical expectations, which points to the benefits of examining social distance among immigrants and natives in conjunction.

Measuring the impact of social-distancing, testing, and undetected asymptomatic cases on the diffusion of COVID-19.

The key to overcoming COVID-19 lies, arguably, in the diffusion process of confirmed cases. In view of this, this study has two main aims: first, to investigate the unique characteristics of COVID-19-for the existence of asymptomatic cases-and second, to determine the best strategy to suppress the diffusion of COVID-19. To this end, this study proposes a new compartmental model-the SICUR model-which can address undetected asymptomatic cases and considers the three main drivers of the diffusion of COVID-19: the degree of social distancing, the speed of testing, and the detection rate of infected cases. Taking each country's situation into account, it is suggested that susceptible cases can be classified into two categories based on their sources of occurrence: internal and external factors. The results show that the ratio of undetected asymptomatic cases to infected cases will, ceteris paribus, be 6.9% for South Korea and 22.4% for the United States. This study also quantitatively shows that to impede the diffusion of COVID-19: firstly, strong social distancing is necessary when the detection rate is high, and secondly, fast testing is effective when the detection rate is low.

Depression and Anxiety Plus Levels of Stress among Secondary School Students during the COVID-19 Lockdown: an Online CrossSectional Survey

Objective: To assess prevalence and factors associated with depression, anxiety and stress among adolescents experiencing lockdown during the 2019 coronavirus disease 2019 (COVID-19) in both Asian and Western countries. Material and Methods: From May-June 2020, secondary school students were enrolled in an online cross-sectional survey, through social media; including, but not limited to, Instagram, Snapchat, WhatsApp and LINE. We assessed the presence and severity of depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder Scale-7) and stress (Perceived Stress Scale-10) within the last month, and assessed significant associations with demographics, degree of social distancing, and other associated issues using univariate and multivariate logistic regression analyses.Results: From 392 respondents (56.4% male, 43.1% female), from Thailand (59.2%), the United Kingdom (26.5%) and other countries (14.3%), we identified depressive symptoms in 58.7%, anxiety in 40.3% and high levels of stress in 9.7%. By multivariate analysis, we found significant associations between being female and depression and anxiety, being in late secondary school years and depression, and changes in patterns of substance use and anxiety and stress. Participants not located in Thailand had increased risk of depression.Conclusion: Our study demonstrated depression, anxiety and stress in six, four and one out of ten adolescents, respectively, who were experiencing lockdowns due to the COVID-19 pandemic. We found female gender, older school years, and changes in substance use patterns to be significantly associated with these mental health conditions.

Hong Kong EFL Learners Politeness Strategy Use in Production and Perception of Requests and Refusals

Requests and refusals are well-acknowledged as challenging speech acts even when realized in native interactions owing to their intrinsic nature of being facethreatening. It is therefore conceivable that producing such social responses would be an arduous task for foreign language learners. Against this background, the present study set out with an aim to examine the politeness in the production of and perception of requests and refusals by six secondary-level EFL learners in Hong Kong under different degrees of social distance and social status, with prospective English teachers and native speakers as the control group. A discourse-completion task and a survey served as the instruments to elicit quantitative data. Results were analyzed with reference to Brown and Levinson’s (1987) politeness theory, which proposes four types of politeness strategies, namely bald on-record, positive politeness, negative politeness and off-record strategy. Findings suggested that intermediate learners had an overuse of direct strategy to threaten both positive and negative face of interlocutors, while advanced learners were reported to be too conventionally indirect in general. Plausible explanation was the insufficient coverage of certain topics at schools. The paper hence demands educational adjustment in relevant aspects to improve learners’ pragmatic performance.

Examining the Impact of Perceived Cultural Distance on the Pragmatic Choices of Saudi Customers in Service Encounters

This study examines service encounters in Saudi Arabia from a pragmatic perspective. Its aim is to investigate the possible impact of perceived cultural distance between customers and service providers on pragmatic choices. It specifically examines how Saudi customers construct their service encounters when talking to service providers of the same (versus different) cultural/ethnic background in terms of discourse structure; strategies of request and internal modifications, and stylistic strategies. Three cafés with service providers of three different ethnic/cultural backgrounds are chosen. One has Saudi service providers, the second café has Arab (non-Saudi) service providers, and the third café has non-Arab service providers. Forty socially minimal service encounter interactions that take place in each café are observed and manually recorded. The study uses the framework of ‘rapport management’ by Spencer-Oatey (2002) as its approach for data analysis. The findings indicate that there are differences among the three sets of data in terms of discourse structure, the realization of the speech act of request, and the stylistic aspect of interactions. According to the special nature of service encounters, customers’ pragmatic choices are explained in terms of expressing certain degrees of social distance rather than politeness. More specifically, the closer cultural distance between customers and service providers, the more pragmatic strategies functioning to achieve more closeness and solidarity are employed.

Social Distancing during COVID-19 Pandemic among Inflammatory Bowel Disease Patients.

(1) Background: Social distancing rules have been widely introduced in the fight against the coronavirus disease 2019 (COVID-19) pandemic. So far, the effectiveness of these methods has not been assessed in the group of inflammatory bowel disease (IBD) patients. (2) Methods: The study included 473 patients with IBD who made 1180 hospital visits from 1 May to 30 September 2020. During each visit, the patients completed a five-step, progressive scale that was developed to assess the degree of social isolation. In parallel, other demographic data were collected and the concentrations of anti-severe acute respiratory coronavirus 2 (SARS-CoV-2) IgG and IgM+IgA antibodies were measured using the ELISA method. (3) Results: The study found a significant correlation between the degree of social distancing and the presence of anti-SARS-CoV-2 antibodies in the groups with the lowest degree of isolation (3 to 5). (4) Conclusions: Maintaining social distancing is an effective method for reducing the spread of SARS-CoV-2 virus among IBD patients.

Correlation between the Level of Social Distancing and Activity of Influenza Epidemic or COVID-19 Pandemic: A Subway Use-Based Assessment.

Social distancing is an effective measure to mitigate the spread of novel viral infections in the absence of antiviral agents and insufficient vaccine supplies. Subway utilization density may reflect social activity and the degree of social distancing in the general population.; This study aimed to evaluate the correlations between subway use density and the activity of the influenza epidemic or coronavirus disease 2019 (COVID-19) pandemic using a time-series regression method. The subway use-based social distancing score (S-SDS) was calculated using the weekly ridership of 11 major subway stations. The temporal association of S-SDS with influenza-like illness (ILI) rates or the COVID-19 pandemic activity was analyzed using structural vector autoregressive modeling and the Granger causality (GC) test. During three influenza seasons (2017–2020), the time-series regression presented a significant causality from S-SDS to ILI (p = 0.0484). During the COVID-19 pandemic in January 2020, S-SDS had been suppressed at a level similar to or below the average of the previous four years. In contrast to the ILI rate, there was a negative correlation between COVID-19 activity and S-SDS. GC analysis revealed a negative causal relationship between COVID-19 and S-SDS (p = 0.0098).; S-SDS showed a significant time-series association with the ILI rate but not with COVID-19 activity. When public transportation use is sufficiently suppressed, additional social mobility restrictions are unlikely to significantly affect COVID-19 pandemic activity. It would be more important to strengthen universal mask-wearing and detailed public health measures focused on risk activities, particularly in enclosed spaces.

The more familiar the others, the higher the morality: children’s preference for familiar others in moral expectations early appears in the negative moral context

ABSTRACT : In order to explore the development mechanism of construction theory in the field of moral judgment, this study investigated the influence of age and social distance on such moral expectations in positive moral context and negative moral context. In both positive and negative moral contexts, 5–6-year-old children had the highest moral expectations of people who are socially closest to them. In negative moral contexts, 3–4-year-old children had significantly higher moral expectations of people who are socially closest to them, whereas in positive moral contexts, no significant difference was noted in their moral expectations of others for various degrees of social distance. These findings suggest that children have lower moral expectations of strangers and exhibit a preference for familiar person in moral expectations as they grow older. And this preference was first observed in contexts which the child thought that someone close to him or her was less likely to do immoral things in negative moral context than to do moral things in positive moral contexts. In conclusion, our study provides empirical evidence for construction theory in the field of moral judgment, proving that social distance, age and moral context strongly affect children’s moral expectations of others.

Social distance of youth of Luhansk region: survey results

The article is devoted to the study of the social distance of the youth of Luhansk region. Social distance described as a certain degree of closeness and remoteness of people in relation to each other. It illustrates social relationships among people of different cultures, nationalities, social groups, so it is relevant for research. Exploring the problem of social distance, the author turns to the scientific works and research of such scientists as R. Park, E. Bogardus, V. Paniotto, N. Panina and others, describing their contribution to the development of science on this topic. The purpose of this article is to study the social distance of young people in Luhansk region, by conducting this study at the local level, which indicates the lack of such experience before. For this purpose, we chose the method of questionnaires, and 418 young people of Luhansk region of different ages and fields of activity acted as respondents. The study used a simplified method of E. Bogardus to measure the degree of social distance of respondents to representatives of certain social groups, and the terminology of interpretation of social distance by N. Panina. Also, a simplified scale of social distance was used, limited to three possible answers: "I agree to communicate with them personally", "I agree to accept them in society, but would like to avoid personal communication" and "No I want them to be in our society in general, ”and not only national minorities but also social groups of a marginal nature and representatives of sexual minorities were chosen as social groups. Particular attention was paid to the description of the results of the study. The study found that young people in Luhansk region have social closeness to residents of the European Union, are tolerant of people with disabilities, people with COVID-19 and IDPs, as well as socially distant from marginalized groups, sexual minorities and more. As a result, it was proved that the students have an average level of social distance.

The <Three Cs> of Japan’s Pandemic Response as an Ideograph

While the COVID-19 pandemic soared across the world and changed the political dynamics on a global scale, Japan was viewed by some news sources as a “miracle” exception that beat the anticipated projections by experts of how the virus would affect the nation. Though there are a number of potential guesses about Japan’s initial pandemic outcome, which include low numbers of testing, an existing culture of mask-wearing, sanitation, and certain degree of social distancing, the political environment and communication from the government have also been accredited to the so-called “success” of Japan’s pandemic experience. By using the concept of ideograph, this study rhetorically analyzes the key slogan that emerged from Japanese political discourse surrounding the COVID-19 situation: 3つの密 - Mittsu no Mitsu (The Three Cs). Specifically, the authors conclude the ways in which < Three Cs > function as a negative ideograph in this specific rhetorical context. By doing so, the authors argue that this slogan that stems from political discourse became culture-bound and serves as a present-day ideological construction in the form of an ideograph for collective governance to (un)justify certain behaviors.

Tele-health and cancer care in the era of COVID-19: New opportunities in low and middle income countries (LMICs)

In the current era of COVID-19 pandemic where at least some degree of social distancing is the norm and hospitals have emerged as hotspots for acquiring the infection, it has become important for oncologists to devise methods of providing care to cancer patients while minimizing patients’ exposure to healthcare settings. In light of the on-going pandemic, it has been recommended that in-patient visits for cancer patients should be substituted by virtual visits and patients should be advised to proceed directly for infusion treatment. Telemedicine and tele-health based interventions have emerged as reasonably practical solutions to these impediments in the delivery of care to cancer patients. Technological advancements have resolved the issue of connectivity for telemedicine even to the remotest places. Teleconsultation is becoming an acceptable alternative for patients and health care providers in this era of information technology. Albeit the challenges that we are facing are diverse and therefore cannot have a singular full proof answer, telemedicine and tele-health based interventions seem to offer promise in effectively complementing our efforts in that direction. Telemedicine is beneficial for both patients and doctors in term to provide quality care without shifting to physical location.

Effectiveness of Adding a Mask Recommendation to Other Public Health Measures to Prevent SARS-CoV-2 Infection in Danish Mask Wearers : A Randomized Controlled Trial.

Observational evidence suggests that mask wearing mitigates transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is uncertain if this observed association arises through protection of uninfected wearers (protective effect), via reduced transmission from infected mask wearers (source control), or both. To assess whether recommending surgical mask use outside the home reduces wearers' risk for SARS-CoV-2 infection in a setting where masks were uncommon and not among recommended public health measures. Randomized controlled trial (DANMASK-19 [Danish Study to Assess Face Masks for the Protection Against COVID-19 Infection]). (ClinicalTrials.gov: NCT04337541). Denmark, April and May 2020. Adults spending more than 3 hours per day outside the home without occupational mask use. Encouragement to follow social distancing measures for coronavirus disease 2019, plus either no mask recommendation or a recommendation to wear a mask when outside the home among other persons together with a supply of 50 surgical masks and instructions for proper use. The primary outcome was SARS-CoV-2 infection in the mask wearer at 1 month by antibody testing, polymerase chain reaction (PCR), or hospital diagnosis. The secondary outcome was PCR positivity for other respiratory viruses. A total of 3030 participants were randomly assigned to the recommendation to wear masks, and 2994 were assigned to control; 4862 completed the study. Infection with SARS-CoV-2 occurred in 42 participants recommended masks (1.8%) and 53 control participants (2.1%). The between-group difference was -0.3 percentage point (95% CI, -1.2 to 0.4 percentage point; P = 0.38) (odds ratio, 0.82 [CI, 0.54 to 1.23]; P = 0.33). Multiple imputation accounting for loss to follow-up yielded similar results. Although the difference observed was not statistically significant, the 95% CIs are compatible with a 46% reduction to a 23% increase in infection. Inconclusive results, missing data, variable adherence, patient-reported findings on home tests, no blinding, and no assessment of whether masks could decrease disease transmission from mask wearers to others. The recommendation to wear surgical masks to supplement other public health measures did not reduce the SARS-CoV-2 infection rate among wearers by more than 50% in a community with modest infection rates, some degree of social distancing, and uncommon general mask use. The data were compatible with lesser degrees of self-protection. The Salling Foundations.

Lockdowns and the COVID-19 pandemic: What is the endgame?

An overall long-term strategy for managing the coronavirus disease 2019 (COVID-19) pandemic is presented. This strategy will need to be maintained until herd immunity is achieved, hopefully through vaccination rather than natural infection. We suggest that a pure test-trace-isolate strategy is likely not practicable in most countries, and a degree of social distancing, ranging up to full lockdown, is the main public-health tool to mitigate the COVID-19 pandemic. Guided by reliable surveillance data, distancing should be continuously optimised down to the lowest sustainable level that guarantees a low and stable infection rate in order to balance its wide-ranging negative effects on public health. The qualitative mixture of social-distancing measures also needs to be carefully optimised in order to minimise social costs.

A Cross-Domain Approach to Analyzing the Short-Run Impact of COVID-19 on the US Electricity Sector.

The novel coronavirus disease (COVID-19) has rapidly spread around the globe in 2020, with the US becoming the epicenter of COVID-19 cases since late March. As the US begins to gradually resume economic activity, it is imperative for policymakers and power system operators to take a scientific approach to understanding and predicting the impact on the electricity sector. Here, we release a first-of-its-kind cross-domain open-access data hub, integrating data from across all existing US wholesale electricity markets with COVID-19 case, weather, mobile device location, and satellite imaging data. Leveraging cross-domain insights from public health and mobility data, we rigorously uncover a significant reduction in electricity consumption that is strongly correlated with the number of COVID-19 cases, degree of social distancing, and level of commercial activity.

Dynamics of Social Mobility During the COVID-19 Pandemic in Canada

As the number of cases increases globally, governments and authorities have continued to use mobility restrictions that were, and still are, the only effective tool to control for the viral transmission. Yet, the relationship between public orders and behavioral parameters of social distancing observed in the community is a complex process and an important policy question. The evidence shows that adherence to public orders about the social distancing is not stable and fluctuates with degree of spatial differences in information and the level of risk aversion. This study aims to uncover the behavioural parameters of change in mobility dynamics in major Canadian cities and questions the role of people's beliefs about how contagious the disease is on the level of compliancy to public orders. Our findings reveal that the degree of social distancing under strict restrictions is bound by choice, which is affected by the departure of people's beliefs from the public order about how severe the effects of disease are. Understanding the dynamics of social distancing thus helps reduce the growth rate of the number of infections, compared to that predicted by epidemiological models.

The novel coronavirus disease (COVID-19) has rapidly spread around the globe in 2020, with the U.S. becoming the epicenter of COVID-19 cases since late March. As the U.S. begins to gradually resume economic activity, it is imperative for policymakers and power system operators to take a scientific approach to understanding and predicting the impact on the electricity sector. Here, we release a first-of-its-kind cross-domain open-access data hub, integrating data from across all existing U.S. wholesale electricity markets with COVID-19 case, weather, cellular location, and satellite imaging data. Leveraging cross-domain insights from public health and mobility data, we rigorously uncover a significant reduction in electricity consumption that is strongly correlated with the number of COVID-19 cases, degree of social distancing, and level of commercial activity.

Jesus vs. the ancestors: how specific religious beliefs shape prosociality on Yasawa Island, Fiji

ABSTRACTWe investigate how religious beliefs in an omnipotent, omniscient God vs. locally concerned, more limited gods impact prosocial behavior at varying degrees of social distance. We recruit participants from traditional villages on Yasawa Island, Fiji. Yasawan religion includes belief in both universalistic Christian teachings and local deified ancestor spirits (Kalou-vu). Yasawans’ contrasting reliance on local, kin-based social networks and anonymous economic market exchange provides an interesting test case for how religious beliefs interact with wider social structures. We use an experimental priming procedure to test whether reminders of Christian vs. traditional imagery, as compared to neutral, influence local or self-favoritism in the random allocation game (RAG). We find that traditional imagery caused increased local – but not self – favoritism. Priming effects depended upon perceived resource uncertainty: participants primed with Christian imagery were most likely to allocate to distant co-religionists when they were least worried about resources. However, more uncertainty predicted higher local RAG allocations, further suggesting the importance of local social networks for managing such uncertainty. We further find additional support for previous findings that prosocial effects of punitive supernatural agent beliefs depend upon uncertainty. These findings further emphasize the interplay between contents of cultural forms like religious belief and socioecological context.

Humans expect generosity

Mechanisms supporting human ultra-cooperativeness are very much subject to debate. One psychological feature likely to be relevant is the formation of expectations, particularly about receiving cooperative or generous behavior from others. Without such expectations, social life will be seriously impeded and, in turn, expectations leading to satisfactory interactions can become norms and institutionalize cooperation. In this paper, we assess people’s expectations of generosity in a series of controlled experiments using the dictator game. Despite differences in respective roles, involvement in the game, degree of social distance or variation of stakes, the results are conclusive: subjects seldom predict that dictators will behave selfishly (by choosing the Nash equilibrium action, namely giving nothing). The majority of subjects expect that dictators will choose the equal split. This implies that generous behavior is not only observed in the lab, but also expected by subjects. In addition, expectations are accurate, matching closely the donations observed and showing that as a society we have a good grasp of how we interact. Finally, correlation between expectations and actual behavior suggests that expectations can be an important ingredient of generous or cooperative behavior.
