There is a populist narrative that authoritarian regimes were better able to respond to the challenges of the COVID-19 pandemic because of their strict enforcement powers, compliance of citizens, and speed of autocratic decision-making in a crisis. Research evidence to date on this assertion is however inconclusive or inconsistent. This paper analyses data from democratic and authoritarian countries with the aim of finding out whether autocratic regimes, using greater stringency measures (policy interventions to tackle COVID-19), had better public health outcomes than their counterparts. The results show that authoritarian regimes performed better in tackling the pandemic in terms of infection and death rates than their counterparts. However, we did not find any empirical evidence on the moderation effect of trust in government on the relationship between stringency measures against COVID-19 and policy outcomes. This result might be due to the lack of data transparency in authoritarian countries.

Even as emperor, Napoleon was concerned with the émigrés. Although his general amnesty for the émigrés, which was promulgated on 26 April 1802, permitted most of the émigrés still inscribed on the ‘general list’ to return to France, it also excluded those belonging to six compromised categories. The number of these exceptions was not to exceed 1,000, the decree stipulating that the first 500 should be named within four months. As it turns out, it actually took the Ministry of Police more than two years to prepare a draft list of exceptions, which ran to more than 800 names. But it was not until 1807 that the first official list of émigrés (la première liste de maintenue) was finally decreed. Surprisingly, that list contained only 171 names. A second list released in 1810 added only 29 more. Examining these much-reduced lists, which have been almost entirely ignored, throws useful light on Napoleon’s continuing worries about the émigrés after 1804. For even then, he saw the Bourbons and the last émigrés as his personal enemies, threats to the security of the Empire, and possibly even reminders of what he saw as his fragile political legitimacy.

We extend the growth-at-risk (GaR) literature by examining US growth risks over 130 years using a time-varying parameter stochastic volatility regression model. This model effectively captures the distribution of GDP growth over long samples, accommodating changing relationships across variables and structural breaks. Our analysis offers several key insights for policymakers. We identify significant temporal variation in both the level and determinants of GaR. The stability of upside risks to GDP growth, as seen in previous research, is largely confined to the Great Moderation period, with a more balanced risk distribution prior to the 1970s. Additionally, the distribution of GDP growth has narrowed significantly since the end of the Bretton Woods system. Financial stress is consistently associated with higher downside risks, without affecting upside risks. Moreover, indicators such as credit growth and house prices influence both downside and upside risks during economic booms. Our findings also contribute to the financial cycle literature by providing a comprehensive view of the drivers and risks associated with economic booms and recessions over time.

Cementitious materials and their alkaline pore fluids can change the structure of bentonite used as a raw material for road embankments or concrete storage of garbage cans. This study investigated the alteration of montmorillonite-rich bentonite from northeast Morocco (Trebia deposit, Nador) in alkaline media rich in Ca2+, Mg2+, Na+, or K+. Specimens based on raw bentonite mixed with variable proportions of oxides (CaO, MgO) or hydroxides (NaOH, KOH) and water were prepared and aged for 28 days. Mineralogical composition by X-ray diffraction (XRD) was determined on raw bentonite and specimens to follow phase changes. Chemical composition and thermal characteristics were determined for raw bentonite and specimens by Fourier-transform infrared spectroscopy (FT-IR) and thermogravimetric/differential thermal analysis (TGA/DTA). Microstructural evolution and alteration of the external surface of bentonite were evaluated using scanning electron microscopy coupled with energy dispersive X-ray (SEM/EDX) analysis. XRD results of bentonite-CaO mixture demonstrated the formation of gels (e.g. C-S-H) and calcite. When the amount of CaO added increased, excess portlandite and the precipitation of calcite in the outer surface of bentonite occurred, stopping pozzolanic reaction and consequently decreasing the compressive strength of specimens. On the other hand, the addition of MgO allowed the formation of brucite. Sodalite and cancrinite were neoformed with the addition of 32 wt.% NaOH after 28 days of hydration. The addition of hydroxides (NaOH or KOH) to bentonite did not reveal any setting due to the absence of the formation of cementitious phases.

This article highlights the cross-disciplinary methodological potential of Third World approaches to international law (TWAIL) and microhistory by studying the active and complex exercise of agency by victims in an understudied historical instance of post-war justice, namely, the Singapore ‘Sook Ching’ trial or Nishimura trial. This trial dealt with the arbitrary massacre of Chinese residents by the Japanese military during the Second World War. Using TWAIL and microhistory methods, this article analyses trial transcripts and archival material on the Nishimura trial, with a focus on the trial experiences of witnesses, survivors, and community representatives. By studying the Nishimura trial as mobilization and meaning-making opportunity, this microhistory draws attention to the exercise of social and political agency by the Chinese community under difficult post-war conditions and British colonial rule. Chinese community leaders represented the community as collectively victimized and united in the pursuit of post-war justice. However, a close analysis of trial transcripts reveals tensions within the community and the need for a more complex understanding of victimhood.

Polyaenus (Strat. 8.23.5) includes an armoured elephant in his description of Julius Caesar crossing a defended ford in Britain (54 b.c.) – something found nowhere in Caesar's own Bellum Gallicum. From looking at a range of loci in the Strategica dealing with Caesar's military exploits in Celtic lands, it becomes clear that, instead of being the remnant of a now-lost source tradition, Polyaenus either based the elephant vignette on an underlying narrative structure provided by the Bellum Gallicum, or a source using this work very closely. Given the overall unlikelihood of Caesar taking an elephant to Britain, Polyaenus probably inserted an elephant for rhetorical and/or didactic purposes and was perhaps influenced by Caesar's own non-literary propaganda involving elephants.

To evaluate the variations in COVID-19 case fatality rates (CFRs) across different regions and waves, and the impact of public health interventions, social and economic characteristics, and demographic factors on COVID-19 CFRs, we collected data from 30 countries with the highest incidence rate in three waves. We summarized the CFRs of different countries and continents in each wave through meta-analysis. Spearman’s correlation and multiple linear regression were employed to estimate the correlation between influencing factors and reduction rates of CFRs. Significant differences in CFRs were observed among different regions during the three waves (P < 0.001). An association was found between the changes in fully vaccinated rates (rs = 0.41), population density (rs = 0.43), the proportion of individuals over 65 years old (rs = 0.43), and the reduction rates of case fatality rate. Compared to Wave 1, the reduction rates in Wave 2 were associated with population density (β = 0.19, 95%CI: 0.05–0.33) and smoking rates (β = −4.66, 95%CI: −8.98 – −0.33), while in Wave 3 it was associated with booster vaccine rates (β = 0.60, 95%CI: 0.11–1.09) and hospital beds per thousand people (β = 4.15, 95%CI: 1.41–6.89). These findings suggest that the COVID-19 CFRs varied across different countries and waves, and promoting booster vaccinations, increasing hospital bed capacity, and implementing tobacco control measures can help reduce CFRs.

We propose a novel time-asymptotically stable, implicit–explicit, adaptive, time integration method (denoted by the $\theta $-method) for the solution of the fractional advection–diffusion-reaction (FADR) equations. The spectral analysis of the method (involving the group velocity and the phase speed) indicates a region of favourable dispersion for a limited range of Péclet number. The numerical inversion of the coefficient matrix is avoided by exploiting the sparse structure of the matrix in the iterative solver for the Poisson equation. The accuracy and the efficacy of the method is benchmarked using (a) the two-dimensional fractional diffusion equation, originally proposed by researchers earlier, and (b) the incompressible, subdiffusive dynamics of a planar viscoelastic channel flow of the Rouse chain melts (FADR equation with fractional time-derivative of order ) and the Zimm chain solution (). Numerical simulations of the viscoelastic channel flow effectively capture the nonhomogeneous regions of high viscosity at low fluid inertia (or the so-called “spatiotemporal macrostructures”), experimentally observed in the flow-instability transition of subdiffusive flows.

Networks among legislators shape politics and policymaking within legislative institutions. In past work on legislative networks, the ties between legislators have been defined on those who serve in the same legislature or chamber. Online information networks, which have been found to play important roles in legislative communication at the national level, are not bounded by individual legislative bodies. We collect original data for over four thousand US state legislators and study patterns of connection among them on Twitter. We look at three types of Twitter networks—follower, retweets, and mentions. We describe these networks and estimate the relationships between ties and salient attributes of legislators. We find that networks are organized largely along geographic and partisan lines and that identity attributes—namely gender and race—exhibit strong associations with the formation of ties.

Thin-film beam combining technology is an effective approach to improve output power while maintaining beam quality. However, the lack of comprehensive research into the key factors affecting the beam quality in systems makes it challenging to achieve a practical combined beam source with high brightness. This paper clearly established that the temperature rise of dichroic mirrors (DMs) and sub-beam overlapping precision are the main factors affecting the beam quality of the system, with quantified effects. Based on this understanding, a combined light source of four channels of 3 kW fiber lasers was achieved, and an output power of 11.4 kW with a beam quality of M2x = 1.601 and M2y = 1.558, using three high-steepness low-absorption DMs and the active control technique. To the best of our knowledge, this is the best beam quality for a 10 kW light source. This study offers a solution for practical high-power laser sources in the tens of kilowatts range.

Legal scholars continue to revisit historical treaties between Western and non-Western nations to challenge long-standing accounts of non-Western peoples’ engagement with international law. Following this trend, new scholarship has stressed African agency in Euro-African treaty-making. However, legal scholars have generally overlooked African perspectives, pointing to a lack of sources. Focusing on nineteenth-century treaty-making between France and the polities of the Western Sudan in West Africa, this article excavates African perspectives through a novel reading of Euro-African treaties in an African context. This reading analyses treaties within the Western Sudan’s broader diplomatic corpus in both French and Arabic. By focusing on markers of translation, transcription, and negotiation left on different copies of treaties, this method brings to light arguments and practices that have been obscured in published European-language versions. Reading Franco-Sudanian treaties in a Sudanian context reveals that different norms governed the ratification of treaties in the Western Sudan and Europe. Treaties that scholars have long considered unratified were in fact ratified according to Western Sudanian norms, which designated the governor of French Senegal rather than the French president as the official competent to ratify treaties for France. However, when French officials sought to use treaties to claim sovereign rights in West Africa against Great Britain, they pressed the president to ratify them again. Presidential ratification thus served to transpose Franco-Sudanian treaties from an African to a Western normative order. Uncovering the African origins of Euro-African treaties thus reveals their differential operation across autonomous inter-polity orders.

Scholars have called for additional research into the antecedents to corporate political activity (CPA), including why firms may engage in specific kinds of CPA. In response, in what we believe to be a first-of-its-kind study, we rely on upper echelons theory to explore the relationship between CEO personality and the kind of CPA in which a firm engages. In particular, we argue that certain traits will be related to ideological CPA (iCPA) that is less beneficial to the firm but which will appeal to CEOs with those traits. We also propose that managerial discretion will moderate the relationship between CEO personality and this form of opportunistic CPA. We test our hypotheses using a unique database combined with a variety of archival sources, resulting in a sample of 329 publicly traded firms from the S&P 500 for which we had complete records that engaged in CPA 63,142 times over a ten-year period (2011–2020). We find that CEO agreeableness, conscientiousness, and neuroticism will be negatively related to iCPA, while CEO openness will be positively associated with it. We further find that managerial discretion moderates the relationship of CEO extraversion and openness with iCPA, however in opposite directions. Finally, we discuss theoretical and managerial implications and propose directions for future research.

On 5 March 2024 the European Court of Justice (CJEU) issued a landmark decision on access to harmonised standards that grant presumption of conformity with legal requirements. The CJEU ruled that such standards should be made available free of charge because, once incorporated in EU legislation, they form part of EU law. While the decision was positively received in the scholarly community, it is expected to carry profound consequences for European standards organisations, who hold copyrights over harmonised standards and rely on their sales to finance their standardisation activities. The judgment may also affect the European Commission, whom the Advocate General and the CJEU placed at the centre of European standardisation due to its role in transforming harmonised standards into EU law. This case note engages with the ruling and aims to shed light onto its possible implications for the European standardisation system.

This article analyses how Labour women MPs championed the needs of ‘the housewife’ in parliament in order to improve the lives of women, especially working-class women, during the Attlee administration. Relying on personal experience to make their case, these women spoke as housewives, not just for housewives, using gendered experiences for political ends. This article examines how they applied the politics of housewifery to two specific contemporary economic challenges: the cost of living and the impact of taxation. In doing so, and in contrast to the established literature, it shows how far Labour women were prepared to challenge party and government policy on behalf of women. It thus contributes to historiographical debates about the Labour party’s relationship to consumerism and affluence as well as gender and austerity. Building on Brian Harrison’s influential study of interwar women MPs, it also responds to a recent call made by Miles Taylor in this journal for more attention to women as legislators in the post-war period. Methodologically, it emphasizes the benefits of qualitative analysis of ‘big data’ sources.
