Field studies were conducted on certified organic land in Lafayette and Vincennes, IN, in 2023 to determine the impact of different between-row weed control methods on weed suppression and sweetpotato yield. Between-row treatments consisted of organic buckwheat (108 kg ha−1) broadcast seeded immediately after sweetpotato transplanting followed by silage tarping from 3 wk after transplanting (WATr) through harvest, organic buckwheat (108 kg ha−1) broadcast seeded 3 WATr and terminated 7 WATr, and cultivation as a grower standard. Weed density at 6 WATr was 0, 184, and 162 plants m−2 for the silage tarping, living mulch buckwheat, and cultivation treatments, respectively. Total yield was 11,048 kg ha−1 for the living mulch buckwheat, 19,792 kg ha−1 for the cultivation, and 17,814 kg ha−1 for the tarping treatments. Tarping effectively suppressed weeds and produced sweetpotato yields comparable to cultivation, indicating the potential for use by organic growers. When buckwheat was grown between rows 3 to 7 WATr, sweetpotato yield was lower than it was with tarping and cultivation. These results suggest that researchers should be evaluating tarps for small-acreage farmers as a weed management strategy.

Forgetting, and having recourse to unremembering the past, is useful for different populations. The modern world has provided a range of examples, but the effectiveness of short-term amnesia has not always been highlighted in archaeological scholarship. In this article, a case study from the Roman-period Netherlands highlights that the significance of memory-making in the past may have been overstated. Especially among those societies living under imperial rule, forgetting played an important role, one that calls for more critical focus and understanding. The utilization of cross-cultural and historical examples provides the background for a close analysis of the remains from a single graveyard. The study brings out the repeated amnesiac changes that indigenous groups underwent to adapt themselves to the continuing fact of occupation.

Although historians have given close attention to the anti-vaccination movement that gripped late-Victorian England, relatively little scholarship explores how doctors and health officials responded or asks what strategies and assumptions structured how they might oppose the vaccine opponents. This article traces the advent and actions of the Jenner Society, a smallpox vaccination advocacy group founded in 1896 by Dr. Francis Bond. His goal was to publicly confront the leading anti-vaccinationists and to effectively conduct an anti-anti-vaccination campaign. The Jenner Society appeared amidst disputes over how and even whether vaccination should be publicly debated – disputes shaped both by long-standing attitudes toward professional propriety and also by indecision about what sorts of political advocacy were suitable for medical practitioners. Vaccination was shifting toward a more voluntary administration, and the Jenner Society represents how civil society, the popular press, and the modern tools of persuasion were becoming increasingly central to public health governance. The Jenner Society encapsulated the profession’s disdainful attitude toward populist medical dissent, and this essay argues that the tone and deportment of anti-anti-vaccinationism had the effect of encouraging doctors to overlook and neglect other, probably more significant, sources of vaccine skepticism. Preoccupied with rebutting and attacking vaccination’s enemies, public “controversialists” like Bond waged the first true large-scale pro-vaccination propaganda campaign, but they ultimately were unable to address the underlying dynamics of vaccine evasion. This history holds important lessons today for those interested in constructing more effective ways to effectively counteract medical misinformation and anti-vaccinationist beliefs.

We investigate flame–acoustic interactions in a turbulent combustor during the state of intermittency before the onset of thermoacoustic instability using complex networks. Experiments are performed in a turbulent bluff-body stabilised dump combustor where the inlet airflow rate is varied quasi-statically and continuously. We construct a natural visibility graph from the local heat release rate fluctuations ($\dot {q}'$) at each location. Comparing the average degree during epochs of high- and low-amplitude acoustic pressure oscillations ($p'$) during the state of intermittency, we detect frequency modulation in $\dot {q}'$. Through this approach, we discover unique spatial patterns of cross-variable coupling between the frequency of $\dot {q}'$ and the amplitude of $p'$. The frequency of $\dot {q}'$ increases in regions of flame anchoring owing to high-frequency excitation of the flow and flame during epochs of high-amplitude $p'$ dynamics. However, the frequency of $\dot {q}'$ decreases in regions associated with flame-front distortions by large coherent vortices. In experiments with continuously varying airflow rates, the spatial pattern of frequency modulation varies with an increase in the average amplitude of $p'$ owing to an increase in the epochs of periodic $p'$ dynamics and the size of vortices forming in the flow. Dynamic shifts in the location of flame anchoring induce low-frequency fluctuations in $\dot {q}'$ during very-high-amplitude intermittent $p'$ dynamics. Our approach using conditional natural visibility graphs thus reveals the spatial pattern of amplitude-frequency coupling between the co-evolving flame and the acoustic field dynamics in turbulent reacting flows.

Anth. Pal. 11.418 is traditionally attributed to Trajan. The distich mocks a man’s large nose and is a typical example of a scoptic epigram. Even though the attribution to Trajan looks suspicious, scholarship has been inclined to accept his authorship. However, it is possible that the poem was written about the emperor instead, which would also explain the misattribution. This hypothesis, if correct, sheds light on the surprising opening anecdote of Plutarch’s Regum et imperatorum apophthegmata (172E), which is dedicated to Trajan.

Haliotis Linnaeus, 1758, a commercially important gastropod, is the only known genus in the family Haliotidae (Mollusca, Vetigastropoda, or abalone) worldwide. Its poor Cenozoic record and high intraspecific variability resulted in different interpretations of nomenclature, impeding a robust species-level taxonomy and biogeographic history. Among the best-studied forms, three subspecies of H. tuberculata Linnaeus, 1758 currently inhabit the temperate waters of the Mediterranean and the eastern Atlantic. New findings in the Pliocene of Tuscany (Italy) are presented here, and the taxonomy of the European record is revised. On the basis of a multivariate analysis of shell morphometrics for the first time applied to the study of fossil abalones, and consistent with the chronostratigraphic and geographic framework, H. plioetrusca n. sp. is introduced and H. volhynica Eichwald, 1829 and H. lamellosoides Sacco, 1897 are reinstated as valid species. Some recently described forms from the Pliocene of Spain are placed in synonymy with H. lamellosoides. Haliotis ovata Michelotti, 1847 is proposed as the ancestral taxon of modern H. tuberculata, via H. lamellosoides. This lineage diversified in the subtropical/warm temperate Pliocene Mediterranean, represented by H. lamellosoides, H. bertinii Forli et al., 2003 and H. plioetrusca. The progressive global cooling starting at around 3.0 Ma is associated with the appearance of H. tuberculata at temperate latitudes. H. plioetrusca is not known from younger strata, whereas H. bertinii survived into the Calabrian.

War, captives, and human sacrifice were parts of Late Postclassic (AD 1250–1524) Maya culture in highland Guatemala. Las Casas (1958:152) wrote that the supreme lord “put the heads of the sacrificed on some poles on a certain altar dedicated only to this, where they had these for some time, after which they buried them.” These cultural aspects show up in human remains excavated at Iximche’, the Kaqchikel Maya capital. Here, we integrate previously published and unpublished results of stable isotope analyses and explore their implications for diets and the geographic origins of individuals who were buried at the site on the eve of the Spanish conquest. Data from Iximche’ are compared with available results from other ancient Maya sites.

Henry “Enrique” Tarrio—the former Afro-Latino leader of the Proud Boys, a right-wing extremist group—positioned himself as a prominent leader of the January 6 insurrection. Our current understanding of Latine politics, and ethnoracial politics more broadly, would call this a striking paradox. Tarrio’s views highlight that Latines’ view of their place in the ethnoracial hierarchy can vary. We argue that an understudied phenomenon, aspirational status, particularly on ethno-cultural and socioeconomic dimensions, can help us understand variation in Latines’ attitudes and behaviors. While some Latines may adopt a minoritized status and align themselves closer to ethnoracial minorities, others may align themselves closer to whites. We explore how these forms of aspirational status, as well as racial resentment, impact Latines’ political attitudes toward the January 6 insurrection. Using the 2020 Collaborative Multiracial Post-Election Survey (CMPS), we find that Latines who aspire to a higher ethno-cultural status that approximates whiteness, as well as those who aspire to a higher socioeconomic status and who distance themselves from Black Americans, are more likely to be supportive of the insurrection. This paper contributes to the overall understanding of the heterogeneity of Latine political attitudes and illustrates the role of status in shaping political attitudes among Latines.

We apply moral foundations theory (MFT) to explore how the public conceptualizes the first eight months of the conflict between Ukraine and the Russian Federation (Russia). Our analysis includes over 1.1 million English tweets related to the conflict over the first 36 weeks. We used linguistic inquiry word count (LIWC) and a moral foundations dictionary to identify tweets’ moral components (care, fairness, loyalty, authority, and sanctity) from the United States, pre- and post-Cold War NATO countries, Ukraine, and Russia. Following an initial spike at the beginning of the conflict, tweet volume declined and stabilized by week 10. The level of moral content varied significantly across the five regions and the five moral components. Tweets from the different regions included significantly different moral foundations to conceptualize the conflict. Across all regions, tweets were dominated by loyalty content, while fairness content was infrequent. Moral content over time was relatively stable, and variations were linked to reported conflict events.

This article examines a frequently overlooked aspect of cuneiform writing in Egypt: the materiality and technology involved in the production of cuneiform tablets, with a particular focus on the process of tablet firing. It is argued that firing was an integral part of tablet production that required learning and practice by the Amarna scribes. The successful firing of tablets to temperatures around 800°C is attributed to the robust and longstanding tradition of tablet manufacture in Mesopotamia, Anatolia, northern Syria and Hazor. In contrast, the lower firing temperatures observed in tablets from Egypt, Alašiya and much of the Levant are associated with the production and firing of cuneiform tablets as a recent technological innovation that required thorough mastery.

The family Dendrophylliidae comprises a genus of azooxanthellate corals, Tubastraea (also known as ‘sun corals’ or ‘cup corals’), native from the Indo-Pacific and introduced into the Atlantic Ocean in the early 1940s. In Brazil, Tubastraea colonies were first registered on oil platforms on the northern coast of Rio de Janeiro state (22°S) in the late 1980s. Two decades later, these corals were for the first time identified in the Todos-os-Santos Bay (Bahia state, 13°S), a warmer environment with diverse marine ecosystems including estuaries, mangroves, and coral reefs. Intending to describe the biological cycle of exotic dendrophylliids from the Brazilian northeastern coast, histological analyses revealed three new reproductive structures for Scleractinia: (1) a mucin layer composed of acid glycoproteins surrounding immature sun coral oocytes, (2) trophonema or specialized cells connecting the oocyte to the adjacent gastrodermis, and (3) nucleolini, small condensations in nucleoli.

This paper explores the evolving landscape of comparative research between ancient Egypt and China, focusing on various aspects such as culture, writing systems, political economy, and motivations behind these comparisons done in China and international environments. Embedded with the historical context, motivations and methodologies of scholars engaged in this comparative endeavour, the authors suggest that such research is linked to modern China's intellectual history and global engagement. It discusses potential motivations, including economic factors, national agenda and interdisciplinary integration. The authors also raise the need for more deliberate theorizations of Egypt–China comparisons, emphasizing the importance of greater reflexivity and inclusivity in shaping the trajectory of comparative studies. Overall, the document sheds light on the complexities, motivations and potential impacts of Egypt–China comparative research, highlighting its relevance in understanding both historical civilizations and contemporary global dynamics.
