Carbon black is commonly used as a filler in the rubber industry. However, it can cause serious damage to human health and to ecosystems. Today, reducing the use of this substance via alternative materials is receiving increased attention. Clay minerals such as montmorillonite can be substituted for carbon black as environmentally friendly fillers for rubber compounds. The uniform dispersion of montmorillonite and its compatibility with the rubber matrix are the main principles for using this material in the rubber industry. To this end, montmorillonite was surface treated with various dosages (1.0, 1.5 and 2.0 wt.%) of polypropylene glycol. The surface-treated montmorillonites were investigated using attenuated total reflection Fourier-transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy and X-ray diffraction analysis. The results indicated that the treatment expanded the interlayer spaces of the montmorillonite and improved surface hydrophobicity. The untreated and treated montmorillonites were used with carbon black as dual fillers in natural rubber/styrene butadiene-based compounds. The cure characteristics, thermal stability, some mechanical properties and dispersion states were evaluated. The curing study indicated a faster optimum cure time, scorch time and increased torque difference for the rubber compounds filled with surface-treated montmorillonites. Thermal analysis of the rubber compounds illustrated that the interval between the initial and final temperature of decomposition could be increased via the treatment. Surface-treated montmorillonite samples, especially the sample containing 1 wt.% polypropylene glycol, showed improved abrasion resistance, resilience and compression set values.

In British North America, imperial sovereignty required peripheral cooperation in public finance. However, because of limited coercive British state capacity, local colonial assemblies and town governments operated with substantial autonomy. The interests of colonial subjects did not align exactly with those of politicians and military officers in the center of British imperial authority in London. Short term success in colonial war between 1754 and 1763 required policies that incentivized colonists to buy into the imperial project. After 1758, Parliament and royal departments managed to incentivize greater provincial participation and resource allocation to the military by co-opting existing colonial merchant networks using lucrative public contracts. The contracts requested a small number of merchant firms in colonial cities take on large debts to circulate notes of credit in exchange for commissions. Merchant financiers could use these notes to pay for military expenses. The contracts promised bullion remittances from England to cover the debts, but these funds ultimately proved insufficient to cover outstanding obligations. Failures to remit led to a colonial credit crisis between 1762 and 1768 which shook colonists’ faith in the credibility of the British fiscal state in the decade leading up to the American Revolution.

Racism permeates societies globally, including within Germany’s educational system. Specifically, people from the SWANA (Southwest Asia and North Africa) region experience anti-Muslim racism. This study explores how racially minoritized parents subjected to the asylum system navigate racist discourse within societal and institutional structures, focusing on their strategies of resistance and accommodation. Guided by a social constructionist epistemology, interviews were conducted with 11 parents migrating from regions and countries with a majority of Muslim residents. Utilizing reflexive thematic analysis, four themes were constructed: Language as an exclusion and excuse mechanism, Meaning-making of being racialized, Good Migrant, and Going the extra mile. The analysis highlights the dialectical tension parents experience as they navigate racist discourse within social and institutional structures. Parents resisted by challenging school practices, defending “cultural norms”, and advocating for their children’s educational opportunities. Simultaneously, they strategically accommodated by stressing gratefulness, assimilation, and praising German systems. This research illuminates how racially minoritized parents navigate oppressive systems and racist discourse, emphasizing the interplay between resistance and accommodation. It underscores the importance of recognizing informal resistance within societal constraints, offering a nuanced perspective through the resistance and accommodation framework. Additionally, it informs policy and social responses to migration by elucidating racialization and oppression dynamics.

This study attempted to determine whether or not the educational curriculum is adjusted in state primary schools to meet the educational needs of Syrian refugee children, whether in-service training related to refugee children’s education was provided, and what the educational needs of refugee students were. The sample was composed of 294 primary school teachers and 372 Syrian refugee students in Türkiye. The data were analysed with Statistical Package for Social Sciences (SPSS) 24 and converted to percentage and frequency tables. The results indicated that the central curriculum and the teacher competencies were inadequate to meet the educational needs of the refugee children. It was also concluded that refugee students typically came from low socio-economic and educational backgrounds, however these students maintained a positive perspective toward education and were dedicated to fulfilling their student responsibilities such as attending school regularly and completing their homework. Some recommendations for future research and practices are presented.

Research on second language (L2) speech learning suggests that incidental perception training can lead to the establishment of non-native phonological categories. The present study contributes to this line of enquiry by investigating how this training is mediated by individual differences in working memory capacity and domain-general auditory processing abilities. In our study, 130 native British English speakers without prior knowledge of Portuguese were randomly assigned to trained or untrained conditions. All participants completed a visual digit span task and an auditory processing test battery. We observed improvements from pretest to post-test in production only, but since both groups improved, these gains cannot be attributed to the incidental perception training. The analysis of the ID measures further confirms the important role played by auditory processing abilities in L2 speech learning. However, more research is needed to better understand the role of incidental perception training and the mediating role of cognitive aptitudes.

Chi jiu zhi ji Tang zhi wu (赤鳩之集湯之屋, “[When] Red Doves Gathered on Tang’s house”) is an excavated Chu manuscript that belongs to the Tsinghua University bamboo slips collection. The manuscript concerns several important early Chinese figures such as Tang and Yi Yin, while also featuring rich supernatural elements. Many studies have focused on “shamanism elements” depicted in the tale or defined the genre of the text as xiaoshuo. This article offers a reexamination of Chi jiu and the above assumptions by contextualizing the text within its original three-text manuscript. The article reveals how early compilers constructed a chronological sequence to frame an overarching narrative in a heterogeneous compilation, and further generates a unique narrative regarding the extraordinary status of Yi Yin the founding minister. In its conclusion, the paper draws attention to potential alternative narratives about the minister-ruler relationship in early China, and also places Chi jiu in the context of early compilation practices. Additionally, it considers possible parallels between the Chi jiu story and two of the Grimms’ Tales, viewing Chi jiu within folklore studies.

Lexical proficiency is a multifaceted phenomenon that greatly impacts human judgments of writing quality. However, the importance of collocations’ contribution to proficiency assessment has received less attention than that of single words, despite collocations’ essential role in language production. This study, therefore, investigated how aspects of collocational proficiency affect the ratings that examiners give to English learner essays. To do so, collocational features related to sophistication and accuracy were manipulated in a set of argumentative essays. Examiners then rated the texts and provided rationales for their choices. The findings revealed that the use of lower-frequency words significantly and positively impacted the experts’ ratings. When used as part of collocations, such words then provided a small yet significant additional boost to ratings. Notably, there was no significant effect for increased collocational accuracy. These findings suggest that low-frequency words within collocations are particularly salient to examiners and deserving of pedagogic focus.

The European Food Safety Authority (EFSA) provides independent scientific advice to EU risk managers on a wide range of food safety issues and communicates on existing and emerging risks in the food chain. This advice helps to protect consumers, animals and the environment. Data are essential to EFSA’s scientific assessments. EFSA collects data from various sources including scientific literature, biological and chemical monitoring programmes, as well as food consumption and composition databases. EFSA also assesses data from authorisation dossiers for regulated products submitted by the industry. To continue delivering the highest value for society, EFSA keeps abreast of new scientific, technological and societal developments. EFSA also engages in partnerships as an essential means to address the growing complexity in science and society and to better connect and integrate knowledge, data and expertise across sectors. This paper provides insights into EFSA’s data-related activities and future perspectives in the following key areas of EFSA’s 2027 strategy: one substance-one assessment, combined exposure to multiple chemicals, environmental risk assessment, new approach methodologies, antimicrobial resistance and risk–benefit assessment. EFSA’s initiatives to integrate societal insights in its risk communication are also described.

Ulrich von Hutten (1488–1523), a renowned sixteenth-century German humanist, documented the symptoms of the epidemic that swept through Europe starting around 1495, commonly known as the French Disease. While it has traditionally been associated with venereal syphilis, Dutch tropical physician Willem F. R. Essed proposed in 1933, largely unnoticed to this day, that this new disease might instead be tropical yaws. This study establishes a clear link between Hutten’s reported symptoms and yaws, especially in its secondary and tertiary stages. The skeleton discovered in 1968 on Ufnau Island in Lake Zurich where Hutten died and was buried, exhibits distinct bone manifestations of ancient treponematosis with a pattern more consistent with yaws than syphilis. Furthermore, the correspondence between Hutten’s main symptoms and the lesions observable on the 1968 skeleton further confirms the identification of these human remains. The historical evidence of yaws significantly contributes to our understanding of this early modern epidemic.

We explore general notions of consistency. These notions are sentences $\mathcal {C}_{\alpha }$ (they depend on numerations $\alpha $ of a certain theory) that generalize the usual features of consistency statements. The following forms of consistency fit the definition of general notions of consistency (${\texttt {Pr}}_{\alpha }$ denotes the provability predicate for the numeration $\alpha $): $\neg {\texttt {Pr}}_{\alpha }(\ulcorner \perp \urcorner )$, $\omega \text {-}{\texttt {Con}}_{\alpha }$ (the formalized $\omega $-consistency), $\neg {\texttt {Pr}}_{\alpha }(\ulcorner {\texttt {Pr}}_{\alpha }(\ulcorner \cdots {\texttt {Pr}}_{\alpha }(\ulcorner \perp \urcorner )\cdots \urcorner )\urcorner )$, and $n\text {-}{\texttt {Con}}_{\alpha }$ (the formalized n-consistency of Kreisel).

We generalize the former notions of consistency while maintaining two important features, to wit: Gödel’s Second Incompleteness Theorem, i.e., (with $\xi $ some standard $\Delta _0(T)$-numeration of the axioms of T), and a result by Feferman that guarantees the existence of a numeration $\tau $ such that $T\vdash \mathcal {C}_\tau $.

We encompass slow consistency into our framework. To show how transversal and natural our approach is, we create a notion of provability from a given $\mathcal {C}_{\alpha }$, we call it $\mathcal {P}_{\mathcal {C}_{\alpha }}$, and we present sufficient conditions on $\mathcal {C}_{\alpha }$ for the notion $\mathcal {P}_{\mathcal {C}_{\alpha }}$ to satisfy the standard derivability conditions. Moreover, we also develop a notion of interpretability from a given $\mathcal {C}_{\alpha }$, we call it $\rhd _{\mathcal {C}_{\alpha }}$, and we study some of its properties. All these new notions—of provability and interpretability—serve primarily to emphasize the naturalness of our notions, not necessarily to give insights on these topics.

An attractive way to address both the climate crisis and the problem of global inequality is to tax rich countries, individuals and businesses, who are responsible for the greater part of carbon emissions, and redistribute the proceeds to create carbon-neutral infrastructure and address human needs through state action (see Raworth 2017 Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist, Penguin Random House; Gough 2017 Heat, Need and Human Greed, Cheltenham: Edward Elgar.). However the dominant value framework in which ideas about wealth, need, and redistribution are embedded centres on deservingness. This largely justifies existing poverty and wealth-holdings, making redistribution within and beyond the rich countries of the global North hard to achieve. Two developments – the ‘deliberative wave’ of citizen participation in government, and the impact of crises in nurturing prosocial values – point to a rapid and sustained value shift. This paper reviews and analyses evidence to consider the practical politics of oughnut economics.

This article discusses early modern North Indian ways of expressing how barrenness could be mapped onto a woman’s maternal identity. Scholars have engaged with the historical evolution of women’s identities, focusing overwhelmingly on their economic and political potential. This article is the first to use medical and erotological sources from the seventeenth and eighteenth centuries to study women as procreative agents, and the socio-sexual anxieties prompted by infertile female bodies. Through a critical study of a wide range of medical material, I demonstrate that by the eighteenth century, several transformations in medical discourses can be mapped onto textual transmissions from Sanskrit (and Braj Bhasha) to Persian, as well as between competing but conterminously flourishing medical paradigms, Ayurveda and Yunani. While cures for childlessness have a much longer history, a new genre of ‘anonymous’ sources, particularly focused on the sexual diseases of men and women emerged in early modern North India. Lastly, my comparative methodological approach to different textual genres will complicate our understanding of early modern medical episteme and its intended audience.

A partir de 2014, a política brasileira foi sacudida pela operação Lava Jato (LJ), uma iniciativa anticorrupção centrada no direito. A LJ expôs um grande esquema de corrupção na empresa nacional de petróleo, a Petrobras, envolvendo seus diretores, dirigentes de partidos políticos e grandes empreiteiras. Para alguns, a LJ representou um marco, um novo capítulo na história do Brasil, promovendo o “estado de direito” e um desejo coletivo de “acabar com a impunidade” na política e nos negócios. Para outros, a operação enfraqueceu a democracia e o estado de direito, abrindo caminho para uma liderança autocrática sob o ex-presidente Jair Bolsonaro. Este artigo contribui para esses debates ao analisar a LJ como um espaço de produção de “consciência jurídica.” Empiricamente, examina conversas lideradas por procuradores da LJ no Facebook entre 2017 e 2019. A questão central abordada é: “Quando os procuradores e o público falavam sobre a LJ, sobre o que falavam?” Os resultados se alinham às visões céticas sobre a operação, sugerindo que as interações entre os procuradores da LJ e seus seguidores no Facebook ajudaram a co-criar um quadro cultural que conflita com o “estado de direito.” Essas percepções oferecem implicações para estudos sobre consciência jurídica e esforços anticorrupção.

Members of the genus Oncicola Travassos, 1916 are generalist parasites able to infect a broad spectrum of carnivorous hosts, such as marsupials, procyonids, felids, and canids, and are distributed globally. Adult specimens were collected from the intestines of three white-nosed coatis (N. narica), whereas cystacanths (larval form) were found in the body cavities of two amphibian species (paratenic hosts) in localities from northern and southeastern Mexico. Morphologically, both stages were identified as O. luehei (Travassos, 1917) on the basis of the following features: trunk cylindrical, narrow anteriorly, enlarging midbody, tapering gradually to narrow posteriorly; proboscis globular with six circular rows of hooks with six hooks each, decreasing in size posteriorly; neck short with sensory papilla; tubular lemnisci long, extending to the posterior region; protonephridia dendritic type; and eight cement glands, compact with a single giant nuclei. Sequences from cytochrome c oxidase subunit 1 from mtDNA were aligned and compared with sequences available in GenBank. Phylogenetic analyses revealed that adults and cystacanths formed a clade with two other isolates identified as Oncicola sp. and O. luehei from Mexico. The intraspecific genetic divergence among the isolates was low, ranging from 0.0% to 3.0%, indicating that the two stages of the life cycle belong to the same species. The haplotype network was inferred with 11 sequences and revealed a lack of shared haplotypes between populations, suggesting a reduced recombination rate and a high pattern of genetic variation among individuals. Finally, these new records of O. luehei increase the distribution range of O. luehei on both coasts of Mexico.

A 15-year-old male presented with vasovagal syncope and troponin leak 4 days after his second COVID-19 vaccine. Based on initial diagnostic work-up, he was thought to have COVID-19 vaccine-associated myocarditis. His cardiac dysfunction persisted and further work-up including genetic evaluation and serial MRI studies later confirmed a diagnosis of arrhythmogenic cardiomyopathy. This is a unique case of an incorrect diagnosis based on timing and context of vaccine-related myocarditis. Reports of mild and self-limited myocarditis post-COVID-19 vaccination may cause vaccine hesitancy among the public, and so case reports such as this one show the importance of discerning underlying conditions amongst rare COVID-19 vaccination complications.

A new species of polychaete annelid, Armandia ramanamurthyi n. sp., is described from the sandy sediments off Tamil Nadu coast, Bay of Bengal, northern Indian Ocean. The major feature distinguishing A. ramanamurthyi n. sp. from other species of the genus is bearing a non-papillated anal tube and the presence of a bulbous, orbicular papilla ventrally placed at the proximal end of the anal tube. The orbicular papilla bears black pigmentation and posteriorly ends in an oblique cirrus. Additionally, Ophelina arabica Parapar, Al-Kandari, Barroso & Moreira, 2023 described from Kuwait waters is recorded for the first time in Indian waters since its original description.

In 1811, Beethoven opted for ‘Allegretto' for the second movement of his seventh symphony, to which he added the metronome mark crotchet = MM76. Ever since the work's inception, however, this has been mitigated by taking it as ‘Andante'. By investigating the purpose, rationale, and background, this article attempts to clarify why the original tempo made performers, listeners, and commentators uncomfortable. Exploring the tension between what Beethoven prescribed and what is taken to be good musicianship, three historical processes are evaluated: (i) performances of the symphony during Beethoven's lifetime; (ii) the activities by Beethoven’s one-time companion Anton Schindler in the 1830s and 40s; and (iii) a vast landscape of interpretational enterprise from the early nineteenth century to the present day.

Following the historical record, the article inquires into the conundrum of Beethoven's intentions, in pursuit of a broader perspective. The case is made that ‘Allegretto' inhered within it an immediacy of performance and that it expressed a repudiation of romantic aesthetics. It is argued that there are good prudential reasons to do away with ‘Andante', an encrustation of romantic error, and to acknowledge, affirm, and valorize ‘Allegretto’ as a thumbprint of style.

The collapse of communism in Eastern Europe did not bring about widespread destruction of the material heritage of communist dictatorships in the region. In fact, given that – on the whole – public acceptance of the regime change has been high, the process of de-commemoration has been more contested than anticipated. This paper focuses on the process of de-commemoration after the fall of communism in Poland. It examines urban residents’ responses to the renaming of streets, paying close attention to the practices and discursive strategies they adopted to resist change. Investigating these responses provides a means of understanding the multifaceted aspects of the contested nature of de-commemoration and sheds light on the ways in which the top-down remaking of urban streetscapes affected local residents. It also enables us to better understand the nature of the post-communist transition in the region and provides insights into the everyday conflicts that underlie symbolic change.
