This study suggests that there may be considerable difficulties in providing accurate calendar age estimates in the Roman period in Europe, between ca. AD 60 and ca. AD 230, using the radiocarbon calibration datasets that are currently available. Incorporating the potential for systematic offsets between the measured data and the calibration curve using the ΔR approach suggested by Hogg et al. (2019), only marginally mitigates the biases in calendar date estimates observed. At present, it clearly behoves researchers in this period to “caveat emptor” and validate the accuracy of their calibrated radiocarbon dates and chronological models against other sources of dating information.

Inaccurate penicillin allergy labeling may deter healthcare providers from initiating appropriate therapy and contribute to antibiotic resistance. In a rural urgent care setting, the current practice of penicillin allergy labeling was evaluated using the PEN-FAST tool. The results confirm opportunity to further evaluate and improve current practice for allergy assessment.

This article considers three “unanswered questions” raised by R. (McConnell) v Registrar General for England and Wales (AIRE Centre Intervening) [2020] EWCA Civ. 559, which held that a trans man (with a Gender Recognition Certificate) who gave birth must be registered as “mother” on his child’s birth certificate. This article considers these questions to clearly situate McConnell within the context of the UK’s legal regimes concerning access to fertility treatment, gender recognition and legal parenthood in cases involving assisted reproduction. The article argues that clearly establishing the current legal position will provide the proper context to facilitate any subsequent legal reforms.

This article explores the financial and geopolitical networks behind the independence of Gran Colombia. It shows that the failure to obtain official British government support for independence was compensated for by the development of a network of private individuals and partnerships that supplied large quantities of arms, equipment and men. A Colombian government document granting ‘Powers’ to London intermediaries was crucial to the construction of this network. We analyse who the key players were and how the network operated. By exploring the decisions and actions of merchants through the lens of risk, trust, credit and networks, we provide a fresh insight into the wider process of independence in Gran Colombia.

The flow of a nematic liquid crystal in a Hele-Shaw cell with an electrically controlled viscous obstruction is investigated using both a theoretical model and physical experiments. The viscous obstruction is created by temporarily electrically altering the viscosity of the nematic in a region of the cell across which an electric field is applied. The theoretical model is validated experimentally for a circular cylindrical obstruction, demonstrating user-controlled flow manipulation of an anisotropic liquid within a heterogeneous single-phase microfluidic device.

There is an urgent need to develop sustainable and impactful interventions to mitigate the high risk of diet-related non-communicable diseases (diet-NCDs) in South Asians living in high-income countries. The current study using a co-design methodology aimed to identify community-led intervention components (solutions) to address barriers and enablers of disease-promoting dietary and physical activity behaviours in New Zealand South Asians. Data were collected from South Asian immigrants aged 25–59 years via three focus group discussions (n = 21) and 10 telephone or face-to-face interviews between 2018 and 2019. The thematic analysis resulted in identifying 22 barrier and enabler codes and 12 solution codes which were summarised under five themes. The key solutions (intervention components) to mitigate the identified target behaviours were providing recipes for using local vegetables in South Asian cuisine, information on the nutritional quality of frozen vegetables and canned lentils, simple home gardening techniques, the saturated fat content of dairy foods, interpreting nutrition labels, optimal portion sizes of foods, and framing low-fat messages positively. Similarly, group-based activities with peer support such as walking, cultural dancing and community sports like cricket, football, and tennis were the identified solutions to increase physical activity levels. The identified solutions for health promoting dietary habits and physical activity levels could be part of any targeted multicomponent health promoting programme to reduce the risk of diet-NCDs in South Asian immigrants.

Meta-learning offers a promising framework to make sense of some parts of decision-making that have eluded satisfactory explanation. Here, we connect this research to work in animal behaviour and cognition in order to shed light on how and whether meta-learning could help us to understand the evolution of cognition.

“Antarctic Ambassadorship” has emerged as an important concept in tourism, conservationist, and polar research communities. This article investigates tourists’ perceptions of “Antarctic Ambassadorship” through surveys and interviews conducted during and shortly after their travel to Antarctica, from 2015 to 2018. Interpretations of the term “Antarctic ambassador” varied widely but most hesitated to identify themselves this way. Tourists were not sure how to enact “Ambassadorship” or whether the actions they did take would “count.” Our findings suggest that the industry has great potential to promote Antarctic Ambassadorship by providing concrete ideas about what Ambassadorship might entail and offering tools for tourists to take concrete actions. We suggest a shift towards a focus on “Antarctic Civics” that would educate travellers about how Antarctica is governed and which institutions are responsible for its conservation, in order to empower tourists to engage in political advocacy in addition to personal lifestyle changes.

During the 1930s and 1940s, a group of right-wing intellectuals, sparked by the New Deal, mounted a sustained critique of American democracy and inherited democratic principles. Believing that the progressive democratization of the state had resulted in a decadent, inefficient and morally coarse society, they attacked democracy as the root cause of the nation's problems. Examining the reactionary conservative, libertarian and fascist critiques of democracy, this article suggests that each borrowed ideas from the other, and that their beliefs in autocratic rule or a broadly countermajoritarian politics have not been adequately studied by scholars.

There is a need for new imaginaries of care and social health for people living with dementia at home. Day programmes are one ‘care in the community’ solution that requires further theorisation to ensure that its empirical base can usefully guide policy. In this paper we contribute to theorising day programmes through an ethnographic case study of one woman living with dementia at home using a day programme. We collected data through observations, interviews and artefacts. We observed Peg, whose case story is central in this paper, over 9 months for a total of 61 hours at the day programme, as well as during 16 hours of observation at her home and 2 community outings. We use a material semiotic approach to thinking about the day programme as a health ‘technology in practice’ to challenge the taken-for-granted ideas of day programmes as neutral, stable, bounded spaces. Peg’s case story is illustrative of how a day programme and its scripts come into relation with an arrangement of family care and life at home with dementia. At times the configuration of this arrangement works to provide a sort of stabilising distribution of care and space to allow Peg and her family to go on in the day-to-day life with dementia. At other times the arrangement may create limits to the care made possible. We argue that how we conceptualise and study day programmes and their relations to home and the broader care infrastructure affects the possibilities of care they can enact.

This study investigated the mental health significance of Barack Obama’s 2012 presidential re-election among Blacks. Upon his re-election, we hypothesized Blacks would either feel symbolic empowerment or relative deprivation. They would feel symbolic empowerment because a man who identifies as Black won re-election to the nation’s highest office. His second victory should generate optimism, given his status as a historic first. Alternatively, they would feel relative deprivation because The Great Recession from 2007 to 2009 curtailed what Obama could achieve. More important, he withered when afforded opportunities to challenge White supremacy and championed individual responsibility. Using a quasi-experimental design with nationally representative survey data from the 2012 Behavioral Risk Factor Surveillance System (BRFSS), we predicted Blacks’ preelection and postelection poor mental health days. We found no time period main effects. However, Black men with less than a college degree experienced 1.11 more poor mental health days postelection whereas Black men with a college degree or more experienced 2.93 fewer poor mental health days postelection. These findings support relative deprivation theory.

This paper aims to provide an analysis of the metatextual function of one of the most well-known elements of Martial's Epigrams, the ‘lion and hare’ cycle from Book 1. This cycle, in which a hare is held precariously but safely in the jaws of a lion, has historically been read as representing the relationship between Domitian and poet. This paper aims to expand on this reading of the cycle while considering a largely unexplored point of view: the metatexual function of this cycle within Martial's larger epigrammatic project. I identify three major ways in which the cycle supports Martial's larger interests in exploring poetic anxieties and defending the genre of epigrammatic poetry. First of all, by figuring the lion and the hare as, respectively, the emperor and the poet, Martial presents and performs an exemplum modelling clemency in the reception of lascivious poetry. Second, as a sexual metaphor that points to the anxiety and insecurity of both predator and prey, the cycle anticipates a broader concern of the Epigrams: the instability of Roman hierarchical relations and the difficulty of maintaining balance within such relationships. Third, Martial's continued use of hare imagery in the later books of the Epigrams, both in culinary and in hunting contexts, suggests the continued consumption and enjoyment of the genre of epigram, particularly outside of the imperial city.

Lower limb rehabilitation robots based on linkage-based mechanisms have recently drawn significant attention in the field due to their numerous advantages. The control of previously proposed linkage-based gait rehabilitation robotic orthoses has been achieved using constant speed control without consideration for the interaction forces. However, such an approach can be harmful to people with stroke since the level of disability varies among individuals, and it may cause potential injuries when excessive force is applied by the robot. To overcome this limitation and improve the rehabilitation process, it is necessary to recognize the force exerted by the person during walking and adjust the robot’s assistive torque accordingly, to provide synchronized motion. Thus, in this work, a human-cooperative approach based on a stiffness control strategy for the six-bar linkage-based gait rehabilitation robot is presented. The proposed methodology can serve as a solid foundation for developing a human-cooperative approach for linkage-based lower limb rehabilitation robotic orthoses. The control was validated and tested with eight healthy human subjects. As a result, customized robotic assistance with this mechanism can be provided during training to meet the individual needs of stroke patients, which can lead to increased engagement and contribution, thus improving treatment outcomes.
