Fearing Fear Itself: Photo Identification Laws, Fear of Fraud, and the Fundamental Right to Vote
In his first inaugural address, President Franklin Roosevelt assured the American people that the only thing we have to fear is fear itself. President Roosevelt\u27s famous statement begs the question, however, of why we should fear fear itself. What, or whom, does fear harm? When faced with the presence of fear, society must consider what steps it is willing to take and what it is willing to give up in order to address that fear. These considerations become particularly acute when the government uses the existence of fear as a rationale for legislation. The propriety of fear-based lawmaking is questionable, since fear is often unreasonable, malleable, and vague.
This debate has recently arisen in the context of state laws that require individuals to present photo identification in order to vote. While proponents generally say that identification requirements are necessary to prevent in-person voter fraud, they have also argued that such laws are necessary to address voter fear. Without photo identification laws, proponents contend, voters will fear that fraud is occurring at the polls. Indeed, states have made this argument even in the absence of any evidence of actual in-person voter fraud. In Crawford v. Marion County Election Board, the Supreme Court accepted the State of Indiana\u27s argument that addressing fear of fraud is a state interest with independent significance apart from the interest in halting actual fraud. In dicta in Purcell v. Gonzalez, the Court likewise expressed approval of laws designed to calm [v]oters who fear their legitimate votes will be outweighed by fraudulent ones
Mental health problems in the general population during and after the first lockdown phase due to the SARS-Cov-2 pandemic: Rapid review of multi-wave studies
Abstract
Aims. The SARS-Cov-2 pandemic and the lockdown response are assumed to have increased
mental health problems in general populations compared to pre-pandemic times. The aim of
this paper is to review studies on the course of mental health problems during and after the
first lockdown phase.
Methods. We conducted a rapid review of multi-wave studies in general populations with
time points during and after the first lockdown phase. Repeated cross-sectional and longitudinal studies that utilised validated instruments were included. The main outcome was
whether indicators of mental health problems have changed during and after the first lockdown phase. The study was registered with PROSPERO No. CRD42020218640.
Results. Twenty-three studies with 56 indicators were included in the qualitative review.
Studies that reported data from pre-pandemic assessments through lockdown indicated an
increase in mental health problems. During lockdown, no uniform trend could be identified.
After lockdown, mental health problems decreased slightly.
Conclusions. As mental health care utilisation indicators and data on suicides do not suggest
an increase in demand during the first lockdown phase, we regard the increase in mental
health problems as general distress that is to be expected during a global health crisis.
Several methodological, pandemic-related, response-related and health policy-related factors
need to be considered when trying to gain a broader perspective on the impact of the first
wave of the pandemic and the first phase of lockdown on general populations’ mental health
Regulation of the Ysh1 endonuclease of the mRNA cleavage/polyadenylation complex by ubiquitinmediated degradation.
Mutation of the essential yeast protein Ipa1 has previously been demonstrated to cause defects in premRNA 3ʹ end processing and growth, but the mechanism underlying these defects was not clear. In this study, we show that the ipa1-1 mutation causes a striking depletion of Ysh1, the evolutionarily
conserved endonuclease subunit of the 19-subunit mRNA Cleavage/Polyadenylation (C/P) complex,
but does not decrease other C/P subunits. YSH1 overexpression rescues both the growth and 3ʹ end
processing defects of the ipa1-1 mutant. YSH1 mRNA level is unchanged in ipa1-1 cells, and proteasome
inactivation prevents Ysh1 loss and causes accumulation of ubiquitinated Ysh1. Ysh1 ubiquitination is
mediated by the Ubc4 ubiquitin-conjugating enzyme and Mpe1, which in addition to its function in C/P,
is also a RING ubiquitin ligase. In summary, Ipa1 affects mRNA processing by controlling the availability
of the C/P endonuclease and may represent a regulatory mechanism that could be rapidly deployed to
facilitate reprogramming of cellular responses.post-print4,60 M
Phantom evaluation of a cardiac SPECT/VCT system that uses a common set of solid-state detectors for both emission and transmission scans
We developed a cardiac SPECT system (X-ACT) with low dose volume CT transmission-based attenuation correction (AC). Three solid-state detectors are configured to form a triple-head system for emission scans and reconfigured to form a 69-cm field-of-view detector arc for transmission scans. A near mono-energetic transmission line source is produced from the collimated fluorescence x-ray emitted from a lead target when the target is illuminated by a narrow polychromatic x-ray beam from an x-ray tube. Transmission scans can be completed in 1 min with insignificant patient dose (deep dose equivalent <5 μSv).
We used phantom studies to evaluate (1) the accuracy of the reconstructed attenuation maps, (2) the effect of AC on image uniformity, and (3) the effect of AC on defect contrast (DC). The phantoms we used included an ACR phantom, an anthropomorphic phantom with a uniform cardiac insert, and an anthropomorphic phantom with two defects in the cardiac insert.
The reconstructed attenuation coefficient of water at 140 keV was .150 ± .003/cm in the uniform region of the ACR phantom, .151 ± .003/cm and .151 ± .002/cm in the liver and cardiac regions of the anthropomorphic phantom. The ACR phantom images with AC showed correction of the bowing effect due to attenuation in the images without AC (NC). The 17-segment scores of the images of the uniform cardiac insert were 78.3 ± 6.5 before and 87.9 ± 3.3 after AC (average ± standard deviation). The inferior-to-anterior wall ratio and the septal-to-lateral wall ratio were .99 and 1.16 before and 1.02 and 1.00 after AC. The DC of the two defects was .528 and .156 before and .628 and .173 after AC.
The X-ACT system generated accurate attenuation maps with 1-minute transmission scans. AC improved image quality and uniformity over NC

Mobile phone use and brain tumour risk - COSMOS, a prospective cohort study
BACKGROUND: Each new generation of mobile phone technology has triggered discussions about potential carcinogenicity from exposure to radiofrequency electromagnetic fields (RF-EMF). Available evidence has been insufficient to conclude about long-term and heavy mobile phone use, limited by differential recall and selection bias, or crude exposure assessment. The Cohort Study on Mobile Phones and Health (COSMOS) was specifically designed to overcome these shortcomings. METHODS: We recruited participants in Denmark, Finland, the Netherlands, Sweden, and the UK 2007-2012. The baseline questionnaire assessed lifetime history of mobile phone use. Participants were followed through population-based cancer registers to identify glioma, meningioma, and acoustic neuroma cases during follow-up. Non-differential exposure misclassification was reduced by adjusting estimates of mobile phone call-time through regression calibration methods based on self-reported data and objective operator-recorded information at baseline. Hazard ratios (HR) and 95% confidence intervals (CI) for glioma, meningioma, and acoustic neuroma in relation to lifetime history of mobile phone use were estimated with Cox regression models with attained age as the underlying time-scale, adjusted for country, sex, educational level, and marital status. RESULTS: 264,574 participants accrued 1,836,479 person-years. During a median follow-up of 7.12 years, 149 glioma, 89 meningioma, and 29 incident cases of acoustic neuroma were diagnosed. The adjusted HR per 100 regression-calibrated cumulative hours of mobile phone call-time was 1.00 (95 % CI 0.98-1.02) for glioma, 1.01 (95 % CI 0.96-1.06) for meningioma, and 1.02 (95 % CI 0.99-1.06) for acoustic neuroma. For glioma, the HR for ≥ 1908 regression-calibrated cumulative hours (90th percentile cut-point) was 1.07 (95 % CI 0.62-1.86). Over 15 years of mobile phone use was not associated with an increased tumour risk; for glioma the HR was 0.97 (95 % CI 0.62-1.52). CONCLUSIONS: Our findings suggest that the cumulative amount of mobile phone use is not associated with the risk of developing glioma, meningioma, or acoustic neuroma

Isolated Case of Bioterrorism-related Inhalational Anthrax, New York City, 2001
On October 31, 2001, in New York City, a 61-year-old female hospital employee who had acquired inhalational anthrax died after a 6-day illness. To determine sources of exposure and identify additional persons at risk, the New York City Department of Health, Centers for Disease Control and Prevention, and law enforcement authorities conducted an extensive investigation, which included interviewing contacts, examining personal effects, summarizing patient’s use of mass transit, conducting active case finding and surveillance near her residence and at her workplace, and collecting samples from co-workers and the environment. We cultured all specimens for Bacillus anthracis. We found no additional cases of cutaneous or inhalational anthrax. The route of exposure remains unknown. All environmental samples were negative for B. anthracis. This first case of inhalational anthrax during the 2001 outbreak with no apparent direct link to contaminated mail emphasizes the need for close coordination between public health and law enforcement agencies during bioterrorism-related investigations
