Amicarbazone, atrazine, and metribuzin behavior was examined in a field setting in Tennessee and in a laboratory setting using soils collected from Illinois and Tennessee. Fields planted to corn were sampled from 0 to 8 cm depth, and the samples were analyzed using methanolic extraction followed by tandem mass spectrometry analysis to determine residual herbicide concentrations. Conditions were favorable for herbicide degradation, including warm temperatures and adequate rainfall. All herbicide half-lives were <10 d. Laboratory research using soils with known atrazine-use histories showed that amicarbazone did not exhibit enhanced microbial degradation due to previous atrazine use. Apparent amicarbazone and metribuzin persistence levels implied that early-season weed control would be expected, but carryover to injure sensitive rotational crops would not be anticipated under these environmental conditions. Dissipation under field conditions of amicarbazone and metribuzin was not affected by being applied to separate plots or by coapplication to the same plots.

This article is about the seminar held at Luiss University in Rome on 17 June 2024. The seminar focused on ‘The End of Christian Democracy: A New Direction for Research’ and was the first milestone and official launch of the PRIN research project ‘The End of Christian Democracy: The Collapse of a Political Dream – Voices from the Margins’, led by a consortium of four universities: Luiss, Roma Tre, Bologna and Suor Orsola Benincasa, Naples.

This paper empirically examines the dynamic relationship between stock market volatility and commodity prices through the time-varying risk aversion channel using daily data between December 31 in 1999 and June 14 in 2021. We employ a time-varying structural-form vector autoregressive model (VAR) model with (aggregate, sectoral and sixteen individual) commodity prices. The results suggest that the transmission mechanism of stock market volatility shocks on the commodity prices change over time. The negative effect of stock market volatility on commodity prices is more statistically significant in the 2008–09 Global Financial Crisis than that during the COVID-19 pandemic in 2020. Further, the effect is greater in energy commodities compared to the agricultural and metals markets. The long-lasting negative effect of risk aversion is stronger compared to that of the expected stock market volatility on the commodity price. The change in the stock-commodity transmission mechanism is likely due to changes in underlying sources of risk aversion and expected uncertainty over time.

This short contribution presents an enigmatic clay mould recovered from a tile kiln in Vindolanda's North Field. This complete mould contains an impression of Apollo in bust form, but its exact use is unclear. This paper presents the mould and discusses its potential use for the manufacture of ceramic figurines. Found in an industrial area of the site, its discovery also provides valuable evidence for craft production along this frontier and hints at a largely unknown provincial industry.

During 2016–2022, Medicare part D beneficiaries filled 8,674,460 clotrimazole-betamethasone dipropionate prescriptions. Annual rates were stable (30.9 prescriptions/1,000 beneficiary-years in 2022, enough for one in every 33 beneficiaries). Diagnostic testing was infrequent, particularly among internal medicine, family medicine, and general practitioners, suggesting potential opportunities to improve diagnostic and prescribing practices.

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.
