This paper considers a new corpus of 490,154 Roman coins (site finds) which have been recorded from England and Wales. The corpus provides British and regional means to aid in the preparation of coin reports in line with Historic England guidelines, along with spatial data providing new opportunities for research. The methods of data collection will be detailed and some of the possibilities this dataset can provide presented through a number of case studies. Through the consideration of applied numismatic analyses, the social distribution of the material and, crucially, the spatial distribution of Roman coinage, we can identify new trends and patterns. Case studies evaluating the fourth century will emphasise the changing importance of settlements in Roman Britain and identify those linked with the late Roman state. Furthermore, the retraction of coinage distributions in the second half of the fourth century will be explored. Building on the national and site type means explored within the paper, the full dataset has been made available in a range of forms on the Archaeology Data Service and in an interactive map developed by Maploom.

This study aimed to explore the combined association between the dietary antioxidant quality score (DAQS) and leisure-time physical activity on sleep patterns in cancer survivors. Data of cancer survivors were extracted from the National Health and Nutrition Examination Surveys database in 2007–2014 in this cross-sectional study. Weighted multivariable logistic regression models were used to estimate OR and 95 % CI for the association of DAQS and leisure-time physical activity on sleep patterns. The combined association was also assessed in subgroups of participants based on age and use of painkillers and antidepressants. Among the eligible participants, 1133 had unhealthy sleep patterns. After adjusting for covariates, compared with low DAQS level combined with leisure-time physical activity level < 600 MET·min/week, high DAQS level combined with leisure-time physical activity ≥ 600 MET·min/week was associated with lower odds of unhealthy sleep patterns (OR = 0·41, 95 % CI: 0·23, 0·72). Additionally, the association of high DAQS level combined with high leisure-time physical activity with low odds of unhealthy sleep patterns was also significant in < 65 years old (OR = 0·30, 95 % CI: 0·13, 0·70), non-painkiller (OR = 0·39, 95 % CI: 0·22, 0·71), non-antidepressant (OR = 0·49, 95 % CI: 0·26, 0·91) and antidepressant (OR = 0·11, 95 % CI: 0·02, 0·50) subgroups. DAQS and leisure-time physical activity had a combined association on sleep patterns in cancer survivors. However, the causal associations of dietary nutrient intake and physical activity with sleep patterns in cancer survivors need further clarification.

Political wrangling over Critical Race Theory (CRT) in the United States has produced policies banning its teaching in jurisdictions across the country. However, laws touted as “anti-CRT” have little in common with the original, academic origins of the phrase. In this study, we use a Qualtrics-based survey experiment to assess how participants’ support for a ban will change depending on whether the ban reflects core tenets of academic researchers’ use of CRT, the phrase itself, or elements common to many of the laws intended to ban it. We find that these three different frames do indeed change support for such policies, and the effects are dependent upon partisanship. We interpret our results to be empirical evidence of the phrase “Critical Race Theory” complicating political discourse.

The nation-state is as much a narrative and ideational project as it is a spatial-territorial one. In the People’s Republic of China, Xi Jinping’s calls to “revitalize” China’s traditional culture, “Sinicize” religions, and “rejuvenate” the Chinese nation reflect a broader effort to reframe the national narrative and strengthen Communist Party control. This article examines the implications of Xi’s revisionist nationalism for China’s fifty-five minority nationalities, in particular the Hui, one of ten Muslim minority groups. It does so by analyzing the rise and demise of World Muslim City (WMC), a development project in western China that mobilized Hui identity and traditions for economic and diplomatic purposes. WMC was facilitated by a multicultural national narrative and by a fragmented authoritarian political system that for many years fostered policy improvisation, and deviation, at the local level. Its suspension underscores the increasingly anti-Muslim, anti-religious tenor of PRC policy, as evidenced by the Sinicization campaign that was a proximate cause of WMC’s demise. Its demise also highlights ongoing efforts to reassert CCP control over government, business, and the Party’s own rank-and-file. The fate of WMC furthermore reveals the spatial dimensions of Sinicization, and of Chinese cultural governance past and present. To paraphrase theorist Henri Lefebvre, Sinicization entails “spatial practices” that impose Xi-ist “representations of space” on lived “representational spaces,” from mosques and businesses to theme parks and luxury resorts.

This paper offers a non-Eurocentric account of raced capitalism in Malaysia, articulated as a developmental state project that has navigated the contested racial logics of British colonialism and Japanese imperialism. By historicising Malaysia’s experience, I provide a reading of the Malaysian developmental state as a project that has taken the form of anti-colonial raced capitalism. This is not meant to valorise raced capitalism as anti-colonial, but to suggest that decolonisation must also confront hegemonic elements engraved on the anti-colonial register of nationalised raced capitalism. In bringing a feminist critique to anti-colonial projects that leave capitalist relations uncontested, the paper makes three contributions. First, it recentres race and colonialism in its analysis of the developmental state, offering anti-colonial raced capitalism as a language that speaks to similar projects that enable, legitimise, and obscure new forms of racial/gender domination with counter-hegemonic frames. Second, it brings back politics to anti-colonialism, reestablishing it as a political space with competing visions, imaginations, and agendas, shaped by the geopolitics of empires. Third, it features gender, social reproduction, and the household as key sites to ground the politics of anti-colonialism, enacting the scaffolding for gendered understandings of raced capitalist development on the periphery of the global economy.

Models of cation exchange mechanisms and driving forces have proven effective predictors of clay behavior and chemistry, but are largely theoretical, particularly in complex systems involving high ionic strength brines or systems where hydration is controlled by relative humidity. In arid and cold environments, such as Mars, cyclical relative humidity variations may play a role in chemical alteration, particularly if clay minerals such as smectite are in the presence of salts. This study examines the effects of relative humidity on smectite-salt mixtures using environmental scanning electron microscopy (ESEM) to observe the physiochemical effects of salt deliquescence and desiccation on smectite textures and elemental distributions. Results demonstrate that even reaction periods as short as a few minutes allow ample time for relative humidity to affect the smectite-salt mixtures. In addition to smectite swelling and salt deliquescence, we also observed rapid changes in element distributions within the smectite and new crystal growth in the presence of high relative humidity. Even in the absence of bulk liquid water, exchangeable cations migrated out of the smectite and formed new crystals at the smectite-salt interface. The observed microscopic changes in elemental distributions indicate that the migration of cations driven by cation exchange led to secondary mineral precipitation, likely a CaSO4 mineral, within a sub-micrometer-thick layer of water on the smectite grains. The results of this study demonstrate that during periods of elevated relative humidity, active smectite mineral alteration and secondary mineral precipitation may be possible on present-day Mars where salts and smectites are in direct physical contact.

Until a few years ago, it was assumed that oocyte renewal did not take place in the ovary of adult organisms; however, the existence of germline progenitor cells (GPCs), which renew the ovarian follicular reserve, has now been documented in mammals. Specifically, in the adult ovary of bats, the presence of cells located in the cortical region with characteristics similar to GPCs, called adult cortical germ cells (ACGC), has been observed. One of the requirements that a GPC must fulfil is to be able to proliferate mitotically, so the evaluation of cell proliferation in ACGC is of utmost importance in order to be able to relate them to a parental lineage. Currently, there are several methods to determine cell proliferation, including BrdU labelling or the use of endogenous proliferation markers. Thus, the aim of this work was to evaluate the proliferative activity of ACGC in the adult ovary of the bat Artibeus jamaicensis, using different proliferation markers and correlating these with the protein expression of the transcription factor Oct4 and the germ line marker Ddx4. We found that the expression pattern of the proliferation markers BrdU, PCNA, Ki-67 and pH3 occurs at different times of the cell cycle, so co-localization of two or more of these markers allows us to identify proliferating cells. This allowed us to identify ACGC with proliferative capacity in the adult ovary of A. jamaicensis, suggesting that GPCs renew the follicle reserve during the adult life of the organism.
