How to hold elections safely and democratically during the COVID-19 pandemic

The COVID-19 pandemic poses major challenges for those charged with overseeing electoral processes, but the innovative ways in which practitioners are addressing these challenges indicate that elections can be safely held even under pandemic conditions. These innovations also represent opportunities for strengthening electoral practices and making them more resilient to a variety of other risks. This briefing draws on existing experience of elections held during the COVID-19 pandemic and previous health crises to address five areas of vulnerability: inclusive and accountable electoral management, poll worker safeguarding, interinstitutional collaboration, feasible and effective election observation, and the risk of electoral violence. The analyses indicate that there are a large number of things that electoral practitioners can do to hold elections safely under pandemic conditions. Most of these are techniques that have been employed previously in some form, and we caution against the introduction of entirely new and untested approaches at the current time. The most useful innovations are those such as widening poll-worker recruitment, inter-institutional coordination and hybrid election observation that build on existing practice. The analyses also highlight the importance of not losing track of the need to bolster the transparency, accountability and security of electoral practices. Far from there being a trade-off between making elections safe in pandemic conditions and achieving these other aims, we argue that efforts to maximise electoral integrity and to preserve electoral peace will also help to ensure that democratic elections can be safeguarded from the risks associated with COVID-19. Our principal recommendations fall into three categories: those targeted at electoral administrators, those aimed at election observation organisations, and general recommendations that are relevant to administrators, observers and electoral assistance providers

Rate-Dependent Nucleation and Growth of NaO2 in Na-O2 Batteries

Understanding the oxygen reduction reaction kinetics in the presence of Na ions and the formation mechanism of discharge product(s) is key to enhancing Na–O2 battery performance. Here we show NaO2 as the only discharge product from Na–O2 cells with carbon nanotubes in 1,2-dimethoxyethane from X-ray diffraction and Raman spectroscopy. Sodium peroxide dihydrate was not detected in the discharged electrode with up to 6000 ppm of H2O added to the electrolyte, but it was detected with ambient air exposure. In addition, we show that the sizes and distributions of NaO2 can be highly dependent on the discharge rate, and we discuss the formation mechanisms responsible for this rate dependence. Micron-sized (∼500 nm) and nanometer-scale (∼50 nm) cubes were found on the top and bottom of a carbon nanotube (CNT) carpet electrode and along CNT sidewalls at 10 mA/g, while only micron-scale cubes (∼2 μm) were found on the top and bottom of the CNT carpet at 1000 mA/g, respectively.Seventh Framework Programme (European Commission) (Marie Curie International Outgoing Fellowship, 2007-2013))National Science Foundation (U.S.) (MRSEC Program, award number DMR-0819762)Robert Bosch GmbH (Bosch Energy Research Network (BERN) Grant)China Clean Energy Research Center-Clean Vehicles Consortium (CERC-CVC) (award number DE-PI0000012)Skolkovo Institute of Science and Technology (Skoltech-MIT Center for Electochemical Energy Storage

Association of antepartum and postpartum depression in Ghanaian and Ivorian women with febrile illness in their offspring: a prospective birth cohort study.

In low-income countries, perinatal depression is common, but longitudinal data on its influence on child health are rare. We examined the association between maternal depression and febrile illness in children. There were 654 mother/child dyads in Ghana and Côte d'Ivoire that were enrolled in a prospective birth cohort in 2010-2011 and underwent 2-years of follow up. Mothers were examined for depression using the Patient Health Questionnaire depression module antepartum and 3 and 12 months postpartum. The hazard of febrile illness in children of depressed and nondepressed mothers was estimated using a recurrent event Cox proportional hazards model. The prevalences of antepartum depression in mothers from Côte d'Ivoire and Ghana were 28.3% and 26.3%, respectively. The prevalences of depression at 3 and 12 months postpartum were 11.8% and 16.1% (Côte d'Ivoire) and 8.9% and 7.2% (Ghana). The crude and adjusted (for country and socioeconomic status) hazard ratios of febrile illness in children of depressed mothers compared with those in children of nondepressed mothers were 1.57 (95% confidence interval: 1.20, 2.07) and 1.32 (95% confidence interval: 1.01, 1.74) respectively. Perinatal depression was frequent and associated with febrile illness in the offspring. Our results showed that a high prevalence of depression in sub-Saharan Africa may pose a serious public health threat to women and their offspring
