This article reconstructs Hannah Arendt's theoretical arguments in relation to current authoritarian-populist crowds, which can be understood as organized mobs of the twenty-first century. Drawn from all classes and originating in societal and political disenfranchisement, in Arendt's understanding they are rebellious nihilists who falsely believe they represent the people as a whole while they exclude any citizens who do not share their tribal nationalism and leader worshiping. Illuminating conditions of their emergence, Arendt also helps to elucidate what drives the populist crowds’ illusions about an uncompromising “sovereign will” they and their leaders claim to embody. Such illusions benefit from broader modern trends eroding differences between facts, opinion, truth, and lies. In public environments suffering from destabilized factual truths, organized lies can easily fill a political vacuum generated by crises of political modernity. Unpacking interrelated theoretical trajectories, it is argued that an Arendtian framework can significantly contribute to the study of present-day authoritarian populism.

Coccidioidomycosis is an infectious fungal disease endemic in Bolivia's Gran Chaco region that is caused by inspiration of the spores of Coccidiodes species. It is a respiratory pathology that can spread to the skeleton and produce diffuse lytic lesions in different parts of the body. This disease has rarely been described in historic populations, and we present here a new case of coccidioidomycosis in a mummified human individual. It corresponds to a female individual with an age at death of 25–35 years, dated to the Tiwanaku epoch of the thirteenth century AD. It was found inside a sepulchral cave near the city of Ulloma in western Bolivia. Radiographic examination shows numerous osseous lytic lesions with central cavitation concentrated on the cranial table and vertebral bodies. The observed condition could correspond to the secondary phase of coccidioidomycosis. This diagnosis is noteworthy because coccidioidomycosis was mainly described as a male work-related disease and has never been found in ancient western Bolivia.

The prints, negatives and albums in the British School at Rome's Thomas Ashby Photographic Archive are a rich assortment of materials created by Ashby and his colleagues, such as Agnes and Dora Bulwer. The archive was the natural and spontaneous product of Ashby's personal and working life and it was not until after his death that it was transferred into the public institutional domain. This article investigates the original intention of Ashby's archive, its transfer from a private to public context, and its subsequent evolution and reception. Building on the work of previous BSR staff and scholars, the article looks at Ashby's archive from a fresh perspective, emphasizing the need to consider the archive's original non-public authorial intent, its polyphonic elements, and the diachronic nature of its formation and reception from Ashby's time to the present. Given that images within photographic archives are now regularly viewed as digital objects, this is a timely discussion of the nature of private photographic archives that have been moved into the public domain. It is now more important than ever that archives like Ashby's are acknowledged as entities with detailed and complex histories, and that these histories are taken into account when viewing the individual photographs within the archive.

To analyse the association of socio-demographic and health factors with vitamin D insufficiency and 25-hydroxyvitamin D (25(OH)D) concentration in Brazilian children aged 6–59 months. Data from 8145 children from the Brazilian National Survey on Child Nutrition (ENANI-2019) were analysed. The serum concentration of 25(OHD)D was measured using a chemiluminescent immunoassay. The prevalence of vitamin D insufficiency (25(OH)D < 50 nmol/l) and 95 % CI was calculated. Logistic and linear regression models were used to identify the variables associated with vitamin D insufficiency and serum 25(OH)D concentrations, respectively. The mean 25(OH)D concentration was 98·6 ± 36·0 nmol/l, and 4·3 % of the children presented vitamin D insufficiency. Children aged 6–23 months (OR = 2·23; 95 % CI 1·52, 3·26); belonging to Southeast (OR = 5·55; 95 % CI 2·34, 13·17) and South (OR = 4·57; 95 % CI 1·77, 11·84) regions; the second tertile of the National Wealth Score (OR = 2·14; 95 % CI 1·16, 3·91) and winter (OR = 5·82; 95 % CI 2·67, 12·71) and spring (OR = 4·84; 95 % CI 2·17, 10·80) seasons of blood collection were associated with a higher chance of vitamin D insufficiency. Female sex (β = −5·66, 95 % CI − 7·81, −3·51), urban location (β = −14·19, 95 % CI −21·0, −7·22) and no vitamin D supplement use (β = −6·01, 95 % CI −9·64, −2·39) were inversely associated with serum 25(OH)D concentration. The age of children and the Brazilian geographical region of household location were the main predictors of vitamin D insufficiency. In Brazil, vitamin D insufficiency among children aged 6–59 months is low and is not a relevant public health problem.

Pseudo-Riemannian manifolds with parallel Weyl tensor that are not conformally flat or locally symmetric, also known as essentially conformally symmetric (ECS) manifolds, have a natural local invariant, the rank, which equals 1 or 2, and is the rank of a certain distinguished null parallel distribution $\mathcal{D}$. All known examples of compact ECS manifolds are of rank one and have dimensions greater than 4. We prove that a compact rank-one ECS manifold, if not locally homogeneous, replaced when necessary by a twofold isometric covering, must be a bundle over the circle with leaves of $\mathcal{D}^\perp$ serving as the fibres. The same conclusion holds in the locally homogeneous case if one assumes that $\,\mathcal{D}^\perp$ has at least one compact leaf. We also show that in the pseudo-Riemannian universal covering space of any compact rank-one ECS manifold, the leaves of $\mathcal{D}^\perp$ are the factor manifolds of a global product decomposition.

We calculated the attributable cost of several healthcare-associated infections in a community hospital network: central-line–associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), hospital-onset Clostridioides difficile infections (CDI-HOs) (43 hospitals); surgical site infections (SSIs) (40 hospitals). From 2016 to 2022, the total cost of CLABSIs, CAUTIs, CDI-HOs, and SSIs was $420,012,025.

With increasing attention to physical human-machine interaction (pHMI), new control methods involving contact force regulation in collaborative and coexistence scenarios have spread in recent years. Thanks to its internal robustness, high dynamic performance, and capabilities to avoid constraint violations, a Model Predictive Control (MPC) action can pose a viable solution to manage the uncertainties involved in those applications. This paper uses an MPC-driven control method that aims to apply a well-defined and tunable force impulse on a human subject. After describing a general control design suitable to achieve this goal, a practical implementation of such a logic, based on an MPC controller, is shown. In particular, the physical interaction considered is the one occurring between the body of a patient and an external perturbation device in a dynamic posturography trial. The device prototype is presented in both its hardware architecture and software design. The MPC-based main control parameters are thus tuned inside hardware-in-the-loop and human-in-the-loop environments to get optimal behaviors. Finally, the device performance is analyzed to assess the MPC algorithm’s accuracy, repeatability, flexibility, and robustness concerning the several uncertainties due to the specific pHMI environment considered.

Across the contemporary world, neoliberalism operates as an anticipatory regime through which mediatised conceptions of the future are aligned to an aggressive (absolute) marketisation of social life. Alongside a critical, queer-theoretical attention to homonormativity, this article uses multimodal critical discourse studies techniques to analyse how such a neoliberal future for LGBTQ people is envisioned in #HoldTight, a pride campaign by an Australian and New Zealand bank. #HoldTight focused on how the act of holding hands can be turned from a source of shame to a joyful, powerful tool for social action: ‘if you feel like letting go, hold tight’. My cultural-phenomenological analysis of #HoldTight demonstrates how this imbrication of LGBTQ rights discourse and mediatised capitalism engaged embodied, hopeful affects as semiotic resources. In this way, I argue that the bank enshrined a speculative, anticipatory chronotope of a future better world, while validating neoliberal governmentality as a benevolent form of LGBTQ agency.
