Published: January 2022

ObjectivesWe previously showed increased coal mining-associated risk of rheumatoid arthritis (RA). Using additional survey data, we sought to delineate this risk further.MethodsWe used data from two cross-sectional, random-digit-dial, population-based surveys (males;≥50 years) in selected counties in the Appalachian region of the inland, mid-Atlantic USA with elevated pneumoconiosis mortality. Surveys ascertained age, smoking, coal mining and non-coal silica exposure jobs. In a subset, we surveyed ergonomic exposures, scored by intensity. We queried diagnosis of RA, corticosteroid use, and, in a subset, use of disease modifying antirheumatic drugs (DMARDs). Multivariable logistic regression modelled RA risk (defined by glucocorticoid or DMARDs use) associated with coal mining employment, other silica exposure, smoking status, and age and ergonomic exposures.ResultsWe analysed data for 2981 survey respondents (mean age 66.6 years; 15% current, 44% ex-smokers). The prevalence of glucocorticoid-treated and DMARD-treated RA was 11% and 4%, respectively. Glucocorticoid-treated RA was associated with coal mining (OR 3.5; 95% CI 2.5 to 4.9) and non-coal mining silica exposure (OR 3.2; 95% CI 2.4 to 4.4). For DMARD-treated RA, the odds associated with coal mining and other silica remained elevated: OR 2.3 (95% CI 1.18, 4.5) and OR 2.7 (95% CI 1.51, 5.0), respectively. In the same model, the highest intensity ergonomic exposure also was associated with increased odds of RA (OR 4.3; 95% CI 1.96 to 9.6).ConclusionsWe observed a strong association between coal mining and other silica-exposing dusty trades and RA. Clinicians and insurers should consider occupational histories in the aetiology of RA.

ObjectivesRecent years have seen an increase in e-liquids containing nicotine salts. Nicotine salts are less harsh and bitter than free-base nicotine and therefore can facilitate inhalation. Because inhalation-facilitating ingredients are banned in the European Union, we assessed the occurrence and characteristics of nicotine salt-containing e-liquids notified for the Netherlands.MethodsWe analysed data for 39 030 products, submitted by manufacturers in the European Union Common Entry Gate system, as extracted on 30 June 2020.ResultsNicotine salts were present in 13% of e-liquids, especially in pod-related e-liquids (73%) and e-liquids registered from 2018 onwards (over 25%). We found six nicotine salt ingredients (NSIs): nicotine lactate, salicylate, benzoate, levulinate, ditartrate and malate. Nicotine salts also occurred as nicotine–organic acid ingredient combination (NAIC), like nicotine and benzoic acid. Nicotine concentrations were twofold higher in e-liquids with NSI (median 14 mg/mL) and NAIC (11 mg/mL) than for free-base nicotine (6 mg/mL). E-liquids with NSI contained a fourfold higher number (median n=17) and concentration (median 31.0 mg/mL) of flavour ingredients than e-liquids with free-base nicotine (n=4, 7.4 mg/mL). In NAIC-containing e-liquids, these were threefold higher (n=12, 21.5 mg/mL). E-liquids with nicotine salts were less often tobacco flavoured but more often had fruity or sweet flavours.ConclusionsA substantial and increasing share of e-liquids in the Netherlands contains nicotine salts. Their characteristics can make such e-liquids more addictive and more attractive, especially to young and beginning users. Policymakers are advised to consider regulating products containing nicotine salts.

IntroductionAs of December 2021, 22 countries and one jurisdiction in WHO African Region (AFRO) have adopted pictorial health warning labels on tobacco packaging, but only 13 have implemented them. In 2014, Senegal enacted a comprehensive tobacco control law, which requires strong provisions on tobacco packaging and labelling. The objective of this study was to assess the level of compliance with these provisions in Senegal 6 months after implementation.MethodsData collection took place in Senegal’s capital city of Dakar across 12 districts in February 2018, following the Tobacco Pack Surveillance System Field Protocol developed by the Institute for Global Tobacco Control at Johns Hopkins Bloomberg School of Public Health. Unique tobacco packs were purchased from a total of 48 tobacco vendors, and compliance with new packaging and labelling provisions was assessed.ResultsIn total, seven unique cigarette packs were confirmed to be legally available for sale in Dakar, Senegal. All packs complied with all health warning provisions (type, size, location, language and quitline information) as well as bans on quantitative emissions yields. However, no pack complied with the descriptive constituents and emissions statement required on the lateral side, and four of the seven packs violated the ban on misleading brand descriptors.ConclusionsAFRO countries have made substantial progress in adopting comprehensive tobacco control laws that bring them closer into alignment with the Framework Convention on Tobacco Control. This study found areas of effective implementation of FCTC recommended packaging and labelling requirements, as well as areas in need of stronger enforcement.
Indistinguishable elements in the origins of quantum statistics. The case of Fermi–Dirac statistics
Authors: Pérez Enric , Ibáñez Joana 
Published: January 2022

AbstractIn this paper, we deal with the historical origins of Fermi–Dirac statistics, focusing on the contribution by Enrico Fermi of 1926. We argue that this statistics, as opposed to that of Bose–Einstein, has been somewhat overlooked in the usual accounts of the old quantum theory. Our main objective is to offer a critical analysis of Fermi’s seminal paper and its immediate impact. Secondly, we are also interested in assessing the status of the particle concept in the years 1926–1927, especially regarding the germ of quantum indistinguishability. We will see, for example, that the first applications of the Fermi–Dirac statistics to the study of metals or stellar matter had a technical nature, and that their main instigators barely touched upon interpretative matters. Finally, we will discuss the reflections and remarks made in these respects in two famous events in physics of 1927, the Como conference and the fifth Solvay congress.

Published: January 2022

Background and Purpose:
Sex-related differences exist in many aspects of acute stroke and were mainly investigated in the early time window with conflicting results. However, data regarding sex disparities in late presenters are scarce. Therefore, we sought to investigate differences in outcomes between women and men treated with endovascular treatment in the late time window.

Methods:
Analyses were based on the SOLSTICE Consortium (Selection of Late-Window Stroke for Thrombectomy by Imaging Collateral Extent), which was an individual-patient level analysis of seven trials and registries. Baseline characteristics, 90-day functional independence (modified Rankin Scale score ≤2), mortality, and symptomatic intracranial hemorrhage were compared between women and men. Effect of sex on the association of age and successful reperfusion (final Thrombolysis in Cerebral Infarction 2b–3) with outcomes was assessed using multivariable logistic regression adjusted for age, National Institutes of Health Stroke Scale score, Alberta Stroke Program Early CT Score, time from onset to puncture, occlusion location, intravenous thrombolysis, and successful reperfusion, with interaction terms.

Results:

Among 608 patients treated with endovascular treatment, 50.5% were women. Women were older than men (median age of 72 versus 68 years,
P
=0.02) and had a lower prevalence of tandem occlusions (14.0% versus 22.9%,
P
=0.005). Workflow times were similar between sexes. Adjusted outcomes did not differ between women and men. Functional independence at 90 days was achieved by 127 out of 292 women (43.5%) and 135 out of 291 men (46.4%). Mortality at 90 days (54 [18.5%] versus 48 [16.5%]) and symptomatic intracranial hemorrhage (37 [13.3%] versus 33 [11.6%]) were similar between women and men. There was no sex-by-age interaction on functional outcomes. However, men had higher likelihood of mortality (
P
interaction
=0.003) and symptomatic intracranial hemorrhage (
P
interaction
=0.017) with advancing age. Sex did not influence the relation between successful reperfusion and outcomes.

Conclusions:
In this multicenter analysis of late patients treated with endovascular treatment, sex was not associated with functional outcome. However, sex influenced the association between age and safety outcomes, with men experiencing worse outcomes with advancing age.
Constitutional Protection of the Right to Self-Determination
Authors: Hamza Marishet Mohammed 
Published: January 2022

Abstract
The right to self-determination is an essential international law principle that holds an erga omnes character. Also, the right is often enshrined under domestic legislation, including constitutions. The 1995 Federal Democratic Republic of Ethiopia Constitution (fdre Constitution) is one such constitution and, uniquely, it explicitly recognizes the right to self-determination including the right of secession as an unconditional right of the nations, nationalities, and peoples in Ethiopia. This paper selects the fdre Constitution and analyses whether such constitutional law frameworks better address some of the contentious matters concerning the right to self-determination under international law. In a comparative perspective (with international law), the article analyses, inter alia, how the fdre Constitution approach the questions of who the subjects of the right to self-determination are, and the substantive guarantees for exercising internal and external aspects of the right to self-determination with particular emphasis on secession as a legal right.
The Dependence of Mean Climate State on Shortwave Absorption by Water Vapor
Authors: Kim Hanjun , Pendergrass Angeline G. , Kang Sarah M. 
Published: January 2022

AbstractState-of-the-art climate models exhibit significant spread in the climatological value of atmospheric shortwave absorption (SWA). This study investigates both the possible causes and climatic impacts of this SWA intermodel spread. The intermodel spread of global-mean SWA largely originates from the intermodel difference in water vapor shortwave absorptivity. Hence, we alter the water vapor shortwave absorptivity in the Community Earth System Model, version 1, with the Community Atmosphere Model, version 4 (CESM1-CAM4). Increasing the water vapor shortwave absorptivity leads to a reduction in global-mean precipitation and a La Niña–like cooling over the tropical Pacific. The global-mean atmospheric energy budget suggests that the precipitation is suppressed as a way to compensate for the increased SWA. The precipitation reduction is driven by the weakened surface winds, stabilized planetary boundary layer, and surface cooling. The La Niña–like cooling over the tropical Pacific is attributed to the zonal asymmetry of climatological evaporative damping efficiency and the low cloud enhancement over the eastern basin. Complementary fixed SSTs simulations suggest that the latter is more fundamental and that it primarily arises from atmospheric processes. Consistent with our experiments, the CMIP5/6 models with a higher global-mean SWA tend to produce tropical Pacific toward a more La Niña–like mean state, highlighting the possible role of water vapor shortwave absorptivity for shaping the mean-state climate patterns.
Testing Vertical Wind Shear and Nonlinear MJO–ENSO Interactions as Predictors for Subseasonal Atlantic Tropical Cyclone Forecasts

Published: January 2022

Abstract
Hansen et al. found patterns of vertical wind shear, relative humidity (RH), and nonlinear interactions between the Madden–Julian oscillation and El Niño–Southern Oscillation that impact subseasonal Atlantic TC activity. We test whether these patterns can be used to improve subseasonal predictions. To do this we build a statistical–dynamical hybrid model using Navy-ESPC reforecasts as a part of the SUBX project. By adding and removing Navy-ESPC reforecasted values of predictors from a logistic regression model, we assess the contribution of skill from each predictor. We find that Atlantic SSTs and the MJO are the most important factors governing subseasonal Atlantic TC activity. RH contributes little to subseasonal TC predictions; however, shear predictors improve forecast skill at 5–10-day lead times, before forecast shear errors become too large. Nonlinear MJO–ENSO interactions did not improve skill compared to separate linear considerations of these factors but did improve the reliability of predictions for high-probability active TC periods. Both nonlinear MJO–ENSO interactions and the subseasonal shear signal appear linked to PV streamer activity. This study suggests that correcting model shear biases and improving representation of Rossby wave breaking is the most efficient way to improve subseasonal Atlantic TC forecasts.
Anti-Corruption Campaign and Firm Financial Performance: Evidence From Vietnam Firms

Published: January 2022

Background Corruption affects businesses in various ways. Anti-corruption, on the other hand, can improve the institutions of the country as well as business operations. Vietnam, as a socialist-oriented country with an ongoing high-profile anti-corruption campaign, provides us a unique setting to evaluate the impacts of anti-corruption on corporate performance. Objectives We address two questions: (1) what is the effect of anti-corruption on the performance of private-owned firms in Vietnam? and (2) how does anti-corruption influence the performance of firms with state ownership (FSOs) in Vietnam? Research design To investigate the impact of anti-corruption on performance of firms with different ownership settings, we use the establishment of the Central Anti-Corruption Steering Committee of Vietnam as a quasi-natural experiment for difference-in-differences analysis. We generate treatment effects of private holding and the state block ownership. To validate the findings, we construct a novel news-based anti-corruption index from Vietnamese online newspapers and use it in a robustness test to evaluate anti-corruption’s impacts on firm performance. Results and Conclusions We find a positive impact of the anti-corruption campaign on private firms’ performance, supporting the social norm perspective of how corruption affects businesses. The empirical results indicate a negative impact of the campaign on FSOs’ performance. The findings suggest that anti-corruption benefits private firms via improving the institutional quality of the country while improving the financial transparency of FSOs. Our study provides a method for measuring anti-corruption which is virtually unobservable and absent in the literature. The findings have implications for policymaking in contemporary Vietnam.
Perfectionism shapes the way adolescents perceive family acceptance over time
Authors: Domocus Iulia M. , Damian Lavinia E. , Benga Oana 
Published: January 2022

Previous theory and research linked perfectionism to contingent self-worth and conditional acceptance, but little research directly investigated how adolescents’ perfectionism and their perceived family acceptance shape each other over time. The present study is the first to investigate the reciprocal longitudinal relations between adolescents’ perfectionism and their perceived family acceptance. The study examined a sample of 264 adolescents (aged 14–19 years) over a period of 3 months, using a cross-lagged longitudinal design with two time points. Results showed that perfectionistic standards predict relative increases, whereas perfectionistic concerns predict relative decreases in adolescents’ perceived mother, father, and family acceptance. However, perceived family acceptance did not predict significant changes in perfectionistic standards nor in perfectionistic concerns. Considering this, the results emphasize the role of perfectionism as a predictor for perceptions of mother, father, and family acceptance and capture how perfectionism may shape interpersonal experiences within the family. Implications of these findings for both research and practice are discussed.
Trait mindfulness and relationship mindfulness are indirectly related to sexual quality over time in dating relationships among emerging adults
Authors: Fincham Frank D. 
Published: January 2022

Trait mindfulness is associated with sexual satisfaction, but their temporal relation is unexplored. Using a short-term longitudinal design, the present study not only examines their temporal relation but also extends extant research by also investigating relationship mindfulness and potential mechanisms that might account for any temporal relation that exists between the two forms of mindfulness and sexual quality. Participants were sexually active emerging adults ( N = 104) in romantic relationships who initially completed measures of trait and relationship mindfulness, and 6 weeks later measures of relationship satisfaction and difficulties in emotion regulation. After another 6 weeks, they completed a measure of sexual quality. Relationship mindfulness was related to sexual satisfaction 12 weeks later via relationship satisfaction, whereas trait mindfulness was related to later sexual dissatisfaction via difficulties in emotion regulation. These results suggest that the temporal relationship between mindfulness and sexual quality is indirect and more nuanced than previously thought. Several avenues for future research are suggested.
MDMA/ecstasy use and psilocybin use are associated with lowered odds of psychological distress and suicidal thoughts in a sample of US adults
Authors: Jones Grant M , Nock Matthew K 
Published: January 2022

Background: Suicide is one of the leading causes of death worldwide and rates within the United States have risen over the past two decades. Hence, there is a critical need for novel tools to treat suicidal ideation and related mental health conditions. 3,4-Methylenedioxymethamphetamine (MDMA)/ecstasy and classic psychedelics may be two such tools. Aims: The aim of this study was to assess non-causal associations between MDMA/ecstasy and classic psychedelic use and psychological distress and suicide risk. Methods: In this study, we examined the aforementioned associations among 484,732 adult participants in the National Survey on Drug Use and Health (2008–2019). Results: Lifetime MDMA/ecstasy use was associated with reduced odds of past year suicidal thinking (10% reduced odds; odds ratio (OR) = 0.90; 95% confidence interval, CI = (0.84–0.97); p < 0.01) and past year suicidal planning (OR = 0.88; 95% CI = (0.78–0.99); p < 0.05). Furthermore, lifetime psilocybin use was associated with reduced odds of past month psychological distress (OR = 0.78; 95% CI = (0.73–0.84); p < 0.001) and past year suicidal thinking (OR = 0.90; 95% CI = (0.83–0.96); p < 0.01). Finally, lysergic acid diethylamide (LSD) was associated with increased odds of past year suicidal thinking (OR = 1.07; 95% CI = (1.00–1.15); p < 0.05). Conclusion: MDMA/ecstasy and psilocybin use are associated with reduced odds of suicidal thinking and related outcomes—though experimental studies are needed to determine whether these associations are causal. These findings call for more research into the efficacy of MDMA/ecstasy and classic psychedelics for treating psychological distress and suicidal thoughts and behaviors, and for updated drug legislation that allows for further investigation into these substances.

Published: January 2022

Introduction: As their name suggests, ‘psychedelic’ (mind-revealing) compounds are thought to catalyse processes of psychological insight; however, few satisfactory scales exist to sample this. This study sought to develop a new scale to measure psychological insight after a psychedelic experience: the Psychological Insight Scale (PIS). Methods: The PIS is a six- to seven-item questionnaire that enquires about psychological insight after a psychedelic experience (PIS-6) and accompanied behavioural changes (PIS item 7). In total, 886 participants took part in a study in which the PIS and other questionnaires were completed in a prospective fashion in relation to a planned psychedelic experience. For validation purposes, data from 279 participants were analysed from a non-specific ‘global psychedelic survey’ study. Results: Principal components analysis of PIS scores revealed a principal component explaining 73.57% of the variance, which displayed high internal consistency at multiple timepoints throughout the study (average Cronbach’s α = 0.94). Criterion validity was confirmed using the global psychedelic survey study, and convergent validity was confirmed via the Therapeutic-Realizations Scale. Furthermore, PIS scores significantly mediated the relationship between emotional breakthrough and long-term well-being. Conclusion: The PIS is complementary to current subjective measures used in psychedelic studies, most of which are completed in relation to the acute experience. Insight – as measured by the PIS – was found to be a key mediator of long-term psychological outcomes following a psychedelic experience. Future research may investigate how insight varies throughout a psychedelic process, its underlying neurobiology and how it impacts behaviour and mental health.
