In the summer of 2020, mitigation efforts slowed the first US wave of the COVID-19 pandemic. Experts warned, however, that without coordinated, sustained mitigation—such as testing and tracing, limited travel or gatherings, social distancing and mask wearing—the worst could lie ahead. A July survey found majority (59%) agreement with the expert warnings, while a minority (27%) mistakenly thought that the worst was behind us, or that COVID-19 was not a real problem. Among frequent Fox News and conservative talk radio consumers, however, large majorities (67–80%) held such false optimism or denial views, in contrast with small minorities (9–16%) among public radio and local television audiences. News media effects on false optimism/denial remain substantial even after controlling for respondent political party and background characteristics. False optimism and denial correlate with lower support for mitigation steps, which worsened the pandemic.

During the early stages of the COVID-19 pandemic, U.S. conservative news downplayed the threat of the virus. Perceived risks of COVID-19 are an important factor in influencing citizens' willingness to comply with risk prevention measures. An online survey (N=269) of U.S. residents was conducted March 30 - April 1, 2020. We found that those who used partisan conservative news sources as their primary source of information about the virus were significantly less likely to view it as a threat, compared to those who cited Far Left, Center Left, and Center Right news sources. Politically conservative Far Right news audiences reported significantly lower estimates of their own COVID-19 risk, as well as that of their age group peers, the average person in the U.S., and the average senior citizen in the U.S.

Social scientists have documented rapid polarization in public opinion about COVID-19 policies. Such polarization is somewhat unsurprising given experimental studies that show opinions on novel issues can diverge quickly in the presence of partisan frames. In this paper I describe a different process that operates alongside polarization: not centrism but a lack of opinion formation. Drawing on four rounds of in-depth interviews with 86 Midwesterners, conducted between June 2019 and November 2020, I take an inductive approach to understanding variation in the processes by which people gathered and interpreted information about COVID-19. I find that those with universal distrust in all media struggled to adjudicate between conflicting interpretations of reality, particularly if they also had low political knowledge. The result was that they felt little confidence in any opinions they formed. These findings suggest that deteriorating trust in media is an important and understudied fact...

The effect of social media consumption on perceptions of the seriousness of the Covid-19 pandemic, attitudes to public health requirements, and intentions towards a future Covid-19 vaccine are of live public health interest. There are also public health and security concerns that the pandemic has been accompanied and arguably further amplified by an ‘infodemic’ spreading misinformation. Tests of the effect of social media consumption on future Covid-19 vaccine intentions using population samples have been relatively few to date. This study contributes to the evidence base by examining social media consumption and vaccine intentions using British and US population samples.Methods: Data were gathered on 1,663 GB adults and 1,198 US adults from an online panel on attitudes towards a future vaccine alongside self-reported social and legacy broadcast and print media consumption. Ordered and binomial logit models were used to assess reported intentions regarding a future Covid-19 vaccine,...

On February 27, 2020 the first case of COVID-19 contagion was detected in Mexico, and by the end of March phase 2 of the epidemic had been declared in the country when local transmission was detected. In a context of crisis and uncertainty like the one described, a risk perception tends to arise among the population that fears to be affected personally, to a large extent due to the influence exerted by the media by information they provide about the contingency, which derived from the media system dependency that occurs in the population. In order to determine the risk perception present in view of the COVID-19 pandemic, as well as the influence that media consumption had on the population’s attitude, an online analytical survey was carried out on 630 Mexican respondents. The results present a population with a relatively low risk perception, but with a moderate dependency when it comes to getting information about everything that has to do with the pandemic. In addition, it is possible to observe that this dependency tends to generate an increase, in an indirect manner, of the risk perception through the consumption of television, the digital press and Facebook.

Aardonyx celestae gen. et sp. nov. is described from the upper Elliot Formation (Early Jurassic) of South Africa. It can be diagnosed by autapomorphies of the skull, particularly the jaws, cervical column, forearm and pes. It is found to be the sister group of a clade of obligatory quadrupedal sauropodomorphs (Melanorosaurus + Sauropoda) and thus lies at the heart of the basal sauropodomorph-sauropod transition. The narrow jaws of A. celestae retain a pointed symphysis but appear to have lacked fleshy cheeks. Broad, U-shaped jaws were previously thought to have evolved prior to the loss of gape-restricting cheeks. However, the narrow jaws of A. celestae retain a pointed symphysis but appear to have lacked fleshy cheeks, demonstrating unappreciated homoplasy in the evolution of the sauropod bulk-browsing apparatus. The limbs of A. celestae indicate that it retained a habitual bipedal gait although incipient characters associated with the pronation of the manus and the adoption of a q...

The hydrologic regime of bottomland hardwood swamps is typically characterized as being determined by the inundation period caused by flood events. However, in the lower coastal plain of South Carolina there are large areas of bottomland hardwood swamps that adjoin freshwater tidal creeks. There has been little work in South Carolina to ascertain whether the tidal creek affects the hydrologic regime of the forested riparian zone. We established a stream stage gauge in Huger Creek, a tidal freshwater creek that drains into the Charleston harbor estuary, and a network of wells in the adjoining riparian zone to assess the hydrologic linkages between the stream and riparian zone. Groundwater levels were influenced by the tidal stream with decreasing affect as distance from the channel increased. Water table behavior adjacent to the creek was primarily controlled by tidal forcing. Groundwater levels in the interior wetland were closely related to stream stage, but mostly lacked the daily...

Devant l'ampleur des attentes sociales (réelles et symboliques) auxquelles est confronté le système éducatif marocain (enseignement de qualité, promotion sociale, intégration au marché de l'emploi…), les différents discours politiques de la réforme<br> ont tendance à se construire/reconstruire à travers la mise à mal des logiques bureaucratiques de gestion. Toutefois, au-delà même du champ éducatif, c'est tout le système de l'administration publique qui est souvent décrié comme bureaucratique (dans une<br> acception péjorative) pléthorique, budgétivore et paralysant (860 000 fonctionnaires, dont 53,6 % travaillent dans le secteur de l'éducation et de la formation).<br> En témoigne les différents rapports d'évaluation de la fonction publique lesquels appellent de leurs voeux à l'urgente nécessité d'inscrire le fonctionnariat dans une logique de gestion par performance et par résultats. Le présent article se propose de réfléchir sur le...

In this study we used the yeast Candida guilliermondii FTI 20037 immobilized by entrapment in Ca-alginate beads (2 .5 -3 mm diameter) for xylitol production from concentrated sugarcane bagasse hemicellulosic hydrolysate in a repeated batch system. The fermentation runs were carried out in 125- and 250-ml Erlenmeyer flasks placed in an orbital shaker at 30 °C and 200 rpm during 72 h, keeping constant the proportion between work volume and flask total volume. According to the results, cell viability was substantially high (98%) in all fermentative cycles. The values of parameters xylitol yield and volumetric productivity increased significantly with the reutilization of the immobilized biocatalysts. The highest values of xylitol final concentration (11.05 g/1), yield factor (0.47 gig) and volumetric productivity (0.22 g/lh) were obtained in 250-ml Erlenmeyer flasks containing 80 ml of medium plus 20 mi of immobilized biocatalysts. The support used in this study (Ca-alginate) presented...

ABO incompatibility is a potential lethal barrier in tranfusion therapy. ABO blood cell grouping for all of the donors and potential recipients is the unique way for ensuring the highest safety for potential recipients in blood transfusion. ABO blood cell grouping must be performed by both of the serum sample method and erythrocytes sample method. Nowadays, when applying the serum sample method, the monoclonal antibodies are commonly used to identify the antigens on the surface of the red blood cells. In this study, for the first time in Vietnam, the hybridoma technology was successefully developed and screened hybrid cells for producing monoclonal antibody specifically agglutinated with red blood cells B group. After being isolated from spleen and iliac lympho node of the human red blood cells B group immuned BALB/c mice, the lymphocytes B was fused with myeloma sp2/0. As the results, 10 single hybrid cell lines B4D6C6, B4D6E2, B4D10C9, B4D10B6, B4D10D5, B4D10D6, B4D10E4, B4H6C5, B...
