Early COVID-19 Government Communication Is Associated With Reduced Interest in the QAnon Conspiracy Theory
Does inadequate risk communication during uncertain times trigger the rise of conspiratorial ideas? We hypothesize that, where government COVID-19 risk communication started early, as measured by the number of days between the start of the communication campaign and the first case in the country, citizens are less likely to turn to conspiratorial explanations for the pandemic, which typically assign blame to powerful actors with secret interests. In Study 1a, we find strong support for our hypothesis in a global sample of 111 countries, using daily Google search volumes for QAnon as a measure of interest in QAnon, which is a conspiracy theory contending, among other things, that COVID-19 is a conspiracy orchestrated by powerful actors and aimed at repressing civil liberties. The effect is robust to a variety of sensitivity checks. In Study 1b, we show that the effect is not explainable by pre-pandemic cross-country differences in QAnon interest, nor by ‘secular’ rising interest in QAnon amid the pandemic. A one-standard deviation (26.2days) increase in communication lateness is associated with a 26% increase in QAnon interest. In pre-registered Study 2, we find limited support for the proposition that early communication reduces self-reported pandemic-related conspiratorial ideation in a sample of respondents from 51 countries. Overall, our results provide evidence that interest in extreme ideas, like QAnon, are highly responsive to government risk communication, while less extreme forms of conspiracism are perhaps less so
Risk Attitudes and Human Mobility during the COVID-19 Pandemic
Behavioral responses to pandemics are less shaped by actual mortality or
hospitalization risks than they are by risk attitudes. We explore human
mobility patterns as a measure of behavioral responses during the COVID-19
pandemic. Our results indicate that risk-taking attitude is a critical factor
in predicting reduction in human mobility and increase social confinement
around the globe. We find that the sharp decline in movement after the WHO
(World Health Organization) declared COVID-19 to be a pandemic can be
attributed to risk attitudes. Our results suggest that regions with risk-averse
attitudes are more likely to adjust their behavioral activity in response to
the declaration of a pandemic even before most official government lockdowns.
Further understanding of the basis of responses to epidemics, e.g.,
precautionary behavior, will help improve the containment of the spread of the
virus
A Behavioral Economics Analysis of Will Making Preferences: When to Begin and Who Should Have the Most Input
The global COVID-19 pandemic has highlighted the need to plan for death, including the transmission of property through a valid will. Surprisingly little is known, however, about when people tend to make wills, how they go about doing so, and whether those practices vary from jurisdiction to jurisdiction. To begin building a foundation of knowledge, a research team comprised of United States and Australian lawyers and economists recently conducted the first-ever behavioral economics empirical study exploring these questions. This Article reports the results of the team\u27s survey of both members of the Australian general public and estate planning lawyers in that country. The research aim was to elicit and compare the attitudes of members of both groups on three questions: (1) when people should begin to plan their estates in anticipation of death; (2) the relative role that the lawyer (compared to the client) should play in the estate planning process; and (3) whether remote witnessing rules for wills--newly adopted during the pandemic in several jurisdictions including states in Australia and the United States--have any impact on individuals\u27 expressed preferences towards will making.
The study yields three significant findings. First, members of the legal profession in Australia tend to prefer the execution of a will at a much younger age than members of the general public do. Estate planning attorneys tend to cite age 29 as the “right” time to make a will, but the general public tends to think that age 47 is best. Second, laypeople in Australia tend to hold widely divergent opinions on the appropriate balance of client vs. professional input into the estate planning process. Those who already have engaged at least once in the will making process tend to desire far greater levels of input from estate planning attorneys than those who have never made a will. Attorneys, in contrast, have relatively uniform views about the same question, tending to cite 70% as the appropriate percentage of estate planning decisions that should be driven by the client. Finally, among both members of the general public and attorneys in Australia, expressed preferences on these matters appear to be largely unaffected by any stated benefits or drawbacks of remotely executed wills.
The survey\u27s focus on Australia was intentional. Australia is an industrialized, democratic country with both a largely capitalist economic and a history of innovation in the law of wills, trusts and estates. Furthermore, Australia\u27s population is smaller than that of the United States, making it easier to obtain a more representative sample. At the same time, we conceive of this study as the beginning point for further, cross-jurisdictional inquiries. Future research can explore whether or how attitudes about will making differ across jurisdictions, using the results reported here as a touchstone. Separate from any country-specific considerations, knowledge about when people make wills, how they do so, and differences between and among jurisdictions will allow lawmakers to make more informed decisions about whether to make permanent some of the pandemic-era rules that enabled the remote online audio-visual witnessing of wills
Spot Focusing Coma Correction by Linearly Polarized Dual-Transmitarray Antenna in the Terahertz Region
Focus scanning is critically important in many terahertz (THz) imaging and
sensing applications. A traditional single focusing transmitarray can achieve a
good focus when the source is on-axis but moving the source off-axis produces a
significant aberration. This paper presents a novel approach to reducing coma
in off-axis scanning in the THz region. Here, a dual transmitarray solution is
proposed, in which a transmitarray with an optimized phase profile is placed
behind a regular phase profile transmitarray. A linearly polarized,
dual-transmitarray antenna was fabricated for validation, and the focusing
performances were experimentally characterized. The measured results are in
good agreement with the theoretical ones. The generated spot of the
dual-transmitarray antenna remains focused on an angle up to 50deg, with a -3
dB spot size of less than 4 mm at 290 GHz. The measured near-field sidelobes
are all below -10 dB within the whole scanning range.Comment: 9 pages, 14 figure
Scientists have favorable opinions on immunity certificates but raise concerns regarding fairness and inequality
Abstract During the first wave of the COVID-19 pandemic, we collected over 12,000 responses from a survey of scientists, who were asked to express their opinions on immunity certificates (also called “immunity passports”) as a potential instrument to lessen the impact of the crisis. Overall, we find that scientists perceive immunity certificates as favorable for public health (50.2%) and the state of the economy (54.4%) while one-fifth (19.1%) and one-sixth (15.4%) disagree. Scientists stipulate some concerns about fairness (36.5%) and inequality (22.4%) arising from implementation of immunity certification. We find some smaller differences among scientific fields, particularly between health scientists and social scientists, with the latter being slightly more positive about the effect of immunity certification. Scholars in the United States, including health scientists, are more likely to view the immunity certificates favorably and mention fewer concerns about this policy’s effect on fairness and inequality. Female scholars are significantly less in favor of immunity certificates, while scientists with more conservative political views hold more favorable opinions. Our results reveal that given the uncertainties during an early phase of a pandemic, scientists see scope for immunity certification to lessen the general societal impacts of the crisis
The effects of increased monitoring on high wealth individuals: Evidence from a quasi-natural experiment in Indonesia
In 2009, Indonesia introduced a specialised tax office focused on High Wealth Individuals (HWIs), increasing the audit probability and monitoring of around 1200 wealthy taxpayers in Jakarta. Leveraging a quasi-natural experiment and analysing 141,097 de-identified individual tax return records between 2006 and 2012, we developed a set of counterfactuals to evaluate the post- and pre-treatment tax declarations of the monitored taxpayers relative to their synthetic control groups. Our results indicate that although post-treatment declaration of taxable and earned income, as well as income tax, increased, the effect was short-lived. The increase in reported earned income was larger relative to taxable income, suggesting that monitored individuals exerted efforts to reduce tax payments. Furthermore, we identified a comparable positive spillover effect on income declaration for non-treated taxpayers in Jakarta who met the HWI criteria. We also demonstrated that the spillover effect drastically decreased as financial characteristics (such as income and wealth) diverged from those of the targeted population. Overall, the additional tax revenue generated from this program is small in comparison to the total tax revenue collected
Qigong Exercise Alleviates Fatigue, Anxiety, and Depressive Symptoms, Improves Sleep Quality, and Shortens Sleep Latency in Persons with Chronic Fatigue Syndrome-Like Illness
Objectives:. To evaluate the effectiveness of Baduanjin Qigong exercise on sleep, fatigue, anxiety, and depressive symptoms in chronic fatigue syndrome- (CFS-) like illness and to determine the dose-response relationship. Methods:. One hundred fifty participants with CFS-like illness (mean age = 39.0, SD = 7.9) were randomly assigned to Qigong and waitlist. Sixteen 1.5-hour Qigong lessons were arranged over 9 consecutive weeks. Pittsburgh Sleep Quality Index (PSQI), Chalder Fatigue Scale (ChFS), and Hospital Anxiety and Depression Scale (HADS) were assessed at baseline, immediate posttreatment, and 3-month posttreatment. The amount of Qigong self-practice was assessed by self-report. Results:. Repeated measures analyses of covariance showed a marginally nonsignificant (P = 0.064) group by time interaction in the PSQI total score, but it was significant for the “subjective sleep quality” and “sleep latency” items, favoring Qigong exercise. Improvement in “subjective sleep quality” was maintained at 3-month posttreatment. Significant group by time interaction was also detected for the ChFS and HADS anxiety and depression scores. The number of Qigong lessons attended and the amount of Qigong self-practice were significantly associated with sleep, fatigue, anxiety, and depressive symptom improvement. Conclusion:. Baduanjin Qigong was an efficacious and acceptable treatment for sleep disturbance in CFS-like illness. This trial is registered with Hong Kong Clinical Trial Register: HKCTR-1380
Association between serum uric acid and prostate cancer mortality in androgen deprivation therapy: A population‐based cohort study
Objective
This population-based study examined the association between baseline uric acid (UA) and prostate cancer (PCa)-related mortality amongst PCa patients receiving androgen deprivation therapy (ADT).
Methods
Adults with PCa who received ADT in Hong Kong between December 1999 and March 2021 were identified. Patients with missing baseline UA were excluded. Patients were followed up until September 2021. The outcome was PCa-related mortality.
Results
Altogether, 4126 patients (median follow-up 3.1[interquartile range 1.4–6.0] years) were included. A J-shaped association was observed between baseline UA level and PCa-related mortality risk, with a direct association in those with mean(0.401 mmol/L) or above-mean baseline UA levels (hazard ratio (HR) per standard deviation-increase 1.35 [95% confidence interval 1.21,1.51], p < 0.001), and an inverse association in those with below-mean baseline UA levels (HR 0.78[0.67,0.92], p = 0.003). The former remained significant on competing risk regression, but not the latter.
Conclusions
A J-shaped relationship between baseline UA level and PCa-related mortality risk was identified. This study was mainly limited by potential unmeasured and residual confounders. Further validation studies are warranted
