The offline roots of online hostility: Adult and childhood administrative records correlate with individual-level hostility on Twitter.

Reducing hostility in social media interactions is a key public concern. Most extant research emphasizes how online contextual factors breed hostility. Here, we take a different perspective and focus on the offline roots of hostility, that is, offline experiences and stable individual-level dispositions.

The COVID-19 pandemic eroded system support but not social solidarity.

While the World was busy mitigating the disastrous health and economic effects of the novel coronavirus, a less direct, but not less concerning peril has largely remained unexplored: the COVID-19 crisis may have disrupted some of the most fundamental social and political relationships in democratic societies. We interviewed samples resembling the national population of Denmark, Hungary, Italy and the US three times: in April, June and December of 2020 (14K observations). We show that multiple (but not all) measures of support for the political system decreased between April and December.

Risk Prediction of New Intracranial Aneurysms at Follow-Up Screening in People With a Positive Family History.

Background: In first-degree relatives of patients with aneurysmal subarachnoid hemorrhage (aSAH), the risk of an intracranial aneurysm can be predicted at initial screening but not at follow-up screening. We aimed to develop a model for predicting the probability of a new intracranial aneurysm after initial screening in people with a positive family history of aSAH.

Methods: In a prospective study, we obtained data from follow-up screening for aneurysms of 499 subjects with ≥2 affected first-degree relatives.

Discriminatory attitudes against unvaccinated people during the pandemic.

During the COVID-19 pandemic, sizeable groups of unvaccinated people persist even in countries with high vaccine access. As a consequence, vaccination became a controversial subject of debate and even protest. Here we assess whether people express discriminatory attitudes in the form of negative affectivity, stereotypes and exclusionary attitudes in family and political settings across groups defined by COVID-19 vaccination status.

Pandemic fatigue fueled political discontent during the COVID-19 pandemic.

Health authorities have highlighted "pandemic fatigue" as a psychological consequence of the COVID-19 pandemic and warned that "fatigue" could demotivate compliance with health-related policies and mandates. Yet, fatigue from following the policies of authorities may have consequences far beyond the health domain. Theories from the social sciences have raised that real and perceived costs of policies can also drive sentiments of discontent with the entire political establishment.

Comparative Study of the Morphology of Cellulose Nanofiber Fabricated Using Two Kinds of Grinding Method.

In this paper, a comparison of cellulose nanofiber (CNF) fabrication from using two kinds of grinding processes is presented. The cellulose from is pretreated with hydrogen peroxide and sodium carbonate in a separating and bleaching process. Then, two grinding processes (method A and B) are used to fabricate CNFs.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning.

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions.

Moralizing the COVID-19 Pandemic: Self-Interest Predicts Moral Condemnation of Other's Compliance, Distancing, and Vaccination.

The emergence of the novel coronavirus has put societies under tremendous pressure to instigate massive and rapid behavior change. Throughout history, an effective strategy to facilitate novel behaviors has been to morally condemn those who do not behave in an appropriate way. Accordingly, here, we investigate if complying with the advice of health authorities-for example, to physically distance or vaccinate-has emerged as a moralized issue during the COVID-19 pandemic.

Do conspiracy theories efficiently signal coalition membership? An experimental test using the "Who Said What?" design.

Theoretical work in evolutionary psychology have proposed that conspiracy theories may serve a coalitional function. Specifically, fringe and offensive statements such as conspiracy theories are expected to send a highly credible signal of coalition membership by clearly distinguishing the speaker's group from other groups. A key implication of this theory is that cognitive systems designed for alliance detection should intuitively interpret the endorsement of conspiracy theories as coalitional cues.

Communicate hope to motivate the public during the COVID-19 pandemic.

How should health authorities communicate to motivate the public to comply with health advice during a prolonged health crisis such as a pandemic? During the SARS-CoV-2 pandemic, for example, people have had to comply with successive restrictions as the world faced multiple races between controlling new waves of the virus and the development and implementation of vaccines. Here, we examine how health authorities and governments most effectively motivate the public by focusing on a specific race: between the Alpha variant and the implementation of the first generation of COVID-19 vaccinations in the winter of 2021. Following prior research on crisis communication, we focus on appeals to fear and hope using communicative aids in the form of visualizations based on epidemiological modelling.

Number of Affected Relatives, Age, Smoking, and Hypertension Prediction Score for Intracranial Aneurysms in Persons With a Family History for Subarachnoid Hemorrhage.

Background: Persons with a positive family history of aneurysmal subarachnoid hemorrhage are at increased risk of aneurysmal subarachnoid hemorrhage. Preventive screening for intracranial aneurysms (IAs) in these persons is cost-effective but not very efficient. We aimed to develop and externally validate a model for predicting the probability of an IA at first screening in persons with a positive family history of aneurysmal subarachnoid hemorrhage.

National identity predicts public health support during a global pandemic.

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g.

Does face mask use elicit risk-compensation? Quasi-experimental evidence from Denmark during the SARS-CoV-2 pandemic.

Background: Public use of face masks has been widely adopted to halter the SARS-CoV-2 pandemic, but a key concern has been whether the effectiveness of face mask use is limited due to the elicitation of false feelings of security that decrease the observance of other protective behaviors, the so-called risk-compensation.

Methods: We exploit quasi-experimental variation, prompted by three major changes in policy, to assess whether public use of face masks elicit risk-compensation by increasing the number of close contacts or decreasing attention to distancing and hygiene measured in daily nationally representative surveys (N = 106 880).

Results: Number of close contacts: face mask use prompted by the policy changes decrease the number of contacts in two of the three interventions.

The Psychological Burden of the COVID-19 Pandemic Is Associated With Antisystemic Attitudes and Political Violence.

What are the consequences of the COVID-19 pandemic for people's political attitudes and behavior? We tested, specifically, whether the psychological burden of the COVID-19 pandemic relates to antisystemic attitudes (dissatisfaction with the fundamental social and political order), peaceful political activism, and political violence. Nationally representative two-wave panel data were collected via online surveys of adults in the United States, Denmark, Italy, and Hungary (s = 6,131 and 4,568 in Waves 1 and 2, respectively). Overall, levels of antisystemic attitudes were low, and only a small share of interviewees reported behavioral intentions to participate in and actual participation in political violence.

Transparent communication about negative features of COVID-19 vaccines decreases acceptance but increases trust.

During the rapid development and rolling out of vaccines against COVID-19, researchers have called for an approach of "radical transparency," in which vaccine information is transparently disclosed to the public, even if negative information can decrease vaccine uptake. Consistent with theories about the psychology of conspiracy beliefs, these calls predict that a lack of transparency may reduce trust in health authorities and may facilitate the spread of conspiracy theories, which may limit the long-term capabilities of health authorities during and after the pandemic. On the basis of preregistered experiments conducted on large, representative samples of Americans and Danes ( > 13,000), the current study contrasts the effects of vague vaccine communication with transparent communication, which discloses either positive or negative vaccine features.

Public acceptance of COVID-19 vaccines: cross-national evidence on levels and individual-level predictors using observational data.

Objectives: The management of the COVID-19 pandemic hinges on the approval of safe and effective vaccines but, equally importantly, on high vaccine acceptance among people. To facilitate vaccine acceptance via effective health communication, it is key to understand levels of vaccine scepticism and the demographic, psychological and political predictors. To this end, we examine the levels and predictors of acceptance of an approved COVID-19 vaccine.

Compliance without fear: Individual-level protective behaviour during the first wave of the COVID-19 pandemic.

Objectives: The outbreak of the COVID-19 pandemic required rapid public compliance with advice from health authorities. Here, we ask who was most likely to do so during the first wave of the pandemic.

Design: Quota-sampled cross-sectional and panel data from eight Western democracies (Denmark, France, Germany, Hungary, Italy, Sweden, the United Kingdom, and the United States).

Effect of Different Raw Material Property for the Fabrication on Al/CNT Nanocomposite Using a Ball Mill with a Discrete Element Method (DEM) Simulation.

Carbon nanotubes (CNTs) have received interest as an attractive reinforcing agent metal matrix composites regarded as an increase to mechanical properties of the final product. Aluminum/carbon nanotubes (Al/CNTs) nanocomposites were observed with different raw material at the optimized experimental condition. In this study, Al-based CNTs composites were three different samples, including un-milled Al, un-milled Al with CNTs, and milled Al with CNTs nanocomposites in the presence of additional CNTs with various experimental conditions while using a traditional ball mill (TBM).

Use of glucose-lowering drugs in Hungary between 2008 and 2017: the increasing use of novel glucose-lowering drug groups.

Aims: To analyse glucose-lowering drug utilization, focusing on the novel glucose-lowering drug groups dipeptidyl peptidase-4 inhibitors, glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter-2 inhibitors, and the financial burden they entail.

Methods: Crude reimbursed national drug utilization and expenditure data for the entire population of Hungary were obtained from the National Health Insurance Fund for the study period: 2008 to 2017. Data were analysed using the WHO's Anatomical Therapeutic Chemical Classification/defined daily dose system and were expressed in defined daily dose per 1000 inhabitants per day.

A Comprehensive Assessment of Apigenin as an Antiproliferative, Proapoptotic, Antiangiogenic and Immunomodulatory Phytocompound.

Apigenin (4',5,7-trihydroxyflavone) (Api) is an important component of the human diet, being distributed in a wide number of fruits, vegetables and herbs with the most important sources being represented by chamomile, celery, celeriac and parsley. This study was designed for a comprehensive evaluation of Api as an antiproliferative, proapoptotic, antiangiogenic and immunomodulatory phytocompound. In the set experimental conditions, Api presents antiproliferative activity against the A375 human melanoma cell line, a G2/M arrest of the cell cycle and cytotoxic events as revealed by the lactate dehydrogenase release.
