The wider case presented by Hanscam and Buchanan (2023), as I understand it, is for archaeologists to consider directly the relation of the past in shaping social and political narratives in the present. I agree that this should happen; I contend it is productively happening already. It is a stretch to argue that the misinterpretation of Hadrian's Wall has been a substantive tool for political justification of US-Mexico border policy, or that archaeologists should make a comparison between such sites just in case someone tries to do so. I am interested in having a conversation about the history of bordering regimes, but why would we make a connection that might be misused in order to clarify that these are not good cases for comparison, beyond that both are walls? In relation to the authors’ problem statement that history is being misused to justify the present, it is notable that the one quotation cited observing a relationship between Hadrian's Wall and present-day US-Mexico border barriers is from The New Yorker—hardly a bastion of jingoistic politics or a go-to source of journalism for the political right. Moreover, the quote expressed caution against making a comparison between Hadrian's wall and contemporary border walling projects.

Alweiss, Lovett, Wu, and Zhang introduced $q$-spread hypergraphs in their breakthrough work regarding the sunflower conjecture, and since then $q$-spread hypergraphs have been used to give short proofs of several outstanding problems in probabilistic combinatorics. A variant of $q$-spread hypergraphs was implicitly used by Kahn, Narayanan, and Park to determine the threshold for when a square of a Hamiltonian cycle appears in the random graph $G_{n,p}$. In this paper, we give a common generalization of the original notion of $q$-spread hypergraphs and the variant used by Kahn, Narayanan, and Park.

This article takes up the short work of fiction Salam, written in Japanese in 2006 by Shirin Nezammafi, and deploys it as a primary source in the history of the Japanese present. Salam tells the tale of Layla, an Afghan migrant detained in and then expelled from Japan in 2001. The article argues that Salam exposes the unmaking of postcolonial Japan: if postcolonial Japan meant a territorial, sovereign nation-state built on hegemonic national myths, then now it is unsustainable. Salam calls to an inevitable if uncharted post-national, post-territorial future. To advance this argument, the article focuses on Nezammafi's treatment of three humanistic categories tied up with geopolitical territoriality: language, art, and gender. These categories, when associated with the nation-state, generate irony in Salam. That irony stems from the anachronism of nations: territorial nations, Japanese or otherwise, appear as past entities that have outlived their possibility.

Fluorbritholite-(Nd), ideally Ca2Nd3(SiO4)3F, has been approved by the International Mineralogical Association (IMA2023–001) and constitutes a new member of the britholite group of the apatite supergroup. It occurs in skarn from the Malmkärra iron mine, Norberg, Västmanland (one of the Bastnäs-type deposits in Sweden), associated with calcite, dolomite, magnetite, lizardite, talc, fluorite, baryte, scheelite, gadolinite-(Nd) and other REE minerals. Fluorbritholite-(Nd) forms anhedral and small grains, rarely up to 250 μm across. They are brownish pink and transparent with a vitreous to greasy lustre. The mineral is brittle, with an uneven or subconchoidal fracture and lacks a cleavage. In thin section, the mineral is nonpleochroic, uniaxial (–). Dcalc = 4.92(1) g⋅cm−3 and ncalc = 1.795. The empirical chemical formula from electron microprobe (WDS) point analyses is (Ca1.62Nd0.97Ce0.83Y0.52Sm0.30Gd0.23Pr0.17La0.16Dy0.11Er0.03Tb0.03Ho0.01Yb0.01)Σ4.99(Si2.92P0.08As0.01)Σ3.01O12.00[O0.48F0.26(OH)0.14Cl0.10Br0.02]Σ1.00. The crystal structure of fluorbritholite-(Nd) was refined from single-crystal X-ray diffraction data to R1= 0.043 for 704 unique reflections. It belongs to the hexagonal system, space group P63/m, with unit cell parameters a = 9.5994(3), c = 6.9892(4) Å and V = 557.76(5) Å3 for Z = 2. Fluorbritholite-(Nd) and other britholite-group minerals are a major sink for neodymium in REE-bearing skarns of Bastnäs type.

Retirement timing is an issue of great political importance these days. Policy-makers develop various initiatives encouraging workers to postpone retirement beyond the statutory retirement age. This effort brings, however, just minimal outcomes. Although increasing opportunities and abilities to work in old age, in some countries people tend to retire as soon as it is possible. In economic terms, they make suboptimal (irrational) decisions.

There is much literature about the licensing of complement clauses by complement-taking predicates. However, less has been written about the licensing of adverbs in a complement clause. This article addresses the licensing of English evidential adverbs in complement clauses extracted from the NOW corpus. The article discusses three factors that determine the distribution of evidential adverbs in complement clauses. These are the nature of the evidential adverbs, the constraints of the complement clause and the anchor of the evidential adverb. To explore the role of these three factors, I adopt the hierarchical scopal theory of Functional Discourse Grammar (FDG). If a complement clause licenses the inclusion of the evidential adverb, then there is a match. Should there be no alignment between the complement clause and the adverb, there will be a mismatch. The results of the analysis of the data show that there are mostly matches, which occur with either a current speaker anchor or an actor anchor. Secondly, it appears that in cases of mismatches, there is always a current speaker. It thus appears that a current speaker anchor can override the constraints of the complement clause.

This article examines Leonard Freed's 1980 Police Work, a photobook that documents the activities of the New York City Police Department from 1973 to 1979. It contextualizes the photobook within this liminal decade after the fullness of the civil rights movement and before the rise of austerity politics. The photobook, I argue, produces a visual repertoire of policing that resolves the crisis of legitimacy faced by the NYPD during this decade, remaking the meaning of the police in the public imaginary from an agent of state warfare into an institution of state welfare. Far from simply creating photographs of policing as community care, Police Work engages in a process by which police violence is visually recoded as police benevolence. The visual politics of the family are central to this process by which we are made not to see police brutality, even when it is placed vividly on display. Ultimately, I show how, even as the camera moves between public and private, Police Work produces an ideology of separate spheres in which the expansion of policing can find its rationalization. Ultimately, this article reveals Police Work as a site through which to examine the intimate, yet often disavowed, entanglements between the domestic and the carceral.

Human brain organoids (HBOs) are three-dimensional biological entities grown in the laboratory in order to recapitulate the structure and functions of the adult human brain. They can be taken to be novel living entities for their specific features and uses. As a contribution to the ongoing discussion on the use of HBOs, the authors identify three sets of reasons for moral concern. The first set of reasons regards the potential emergence of sentience/consciousness in HBOs that would endow them with a moral status whose perimeter should be established. The second set of moral concerns has to do with an analogy with artificial womb technology. The technical realization of processes that are typically connected to the physiology of the human body can create a manipulatory and instrumental attitude that can undermine the protection of what is human. The third set concerns the new frontiers of biocomputing and the creation of chimeras. As far as the new frontier of organoid intelligence is concerned, it is the close relationship of humans with new interfaces having biological components capable of mimicking memory and cognition that raises ethical issues. As far as chimeras are concerned, it is the humanization of nonhuman animals that is worthy of close moral scrutiny. A detailed description of these ethical issues is provided to contribute to the construction of a regulative framework that can guide decisions when considering research in the field of HBOs.

In March 2020, the Government of Ontario, Canada implemented public health measures, including visitor restrictions in institutional care settings, to protect vulnerable populations, including older adults (> 65 years), against COVID-19 infection. Prior research has shown that visitor restrictions can negatively influence older adults’ physical and mental health and can cause increased stress and anxiety for care partners. This study explores the experiences of care partners separated from the person they care for because of institutional visitor restrictions during the COVID-19 pandemic. We interviewed 14 care partners between the ages of 50 and 89; 11 were female. The main themes that emerged were changing public health and infection prevention and control policies, shifting care partner roles as a result of visitor restrictions, resident isolation and deterioration from the care partner perspective, communication challenges, and reflections on the impacts of visitor restrictions. Findings may be used to inform future health policy and system reforms.

For archaeology to survive in the present and for critical discourse on the past to thrive, archaeologists must advocate for the discipline's continued relevancy. In this Debate article, the authors illustrate the potential and challenges of such advocacy by examining contemporary perceptions of the Roman period Hadrian's Wall and how it relates to modern border landscapes—namely the US/Mexico border. They argue that archaeologists have not addressed the imagined continuity of socio-political narratives surrounding borderlands, calling for wider recognition of border materiality. The authors contend that the uncritical portrayal of the past, particularly in politically charged spaces such as border zones, can contribute to inequality and oppression in the present.

The study addresses the absence of a comprehensive institutional analysis framework in the academic literature on state-minority relations. It does so by employing a framework of analysis based on Skocpol’s analysis of structural factors and Ostrom’s multi-level institutional analysis to understand the processes of radical and incremental institutional change. The article is empirically grounded in a case study of Roma communities in Slovakia. More specifically, it maps and analyzes the evolution and change of institutional frameworks of state-minority relations in the context of Roma communities in Slovakia from the 1960s to 2020. Drawing from archival materials, interview findings, and document analysis, this article shows how post-socialist Slovakia radically redefined and diversified its institutional framework for Roma communities at different institutional levels, which subsequently continued to change at an incremental pace. Overall, the study aspires to offer a more dynamic institutional approach to the study of state-minority relations, which are currently dominated by more static regime- and rights-based approaches, and to contribute with a prospectively useful framework for understanding the developments of state-minority relations in the broader post-Soviet space and beyond.

We analyse the $\Gamma$-convergence of general non-local convolution type functionals with varying densities depending on the space variable and on the symmetrized gradient. The limit is a local free-discontinuity functional, where the bulk term can be completely characterized in terms of an asymptotic cell formula. From that, we can deduce an homogenisation result in the stochastic setting.

Commercial application of embryo transfer in pig breeding is dependent on the storage of embryos. The aim of this study was to assess the embryo quality of in vitro-produced blastocysts after 3 h liquid storage at 37°C in CO2-free medium by evaluating morphology, in vitro developmental capacity and apoptosis. Blastocysts at days 5 and 6 post-fertilization were randomly allocated to the storage group (HEPES-buffered NCSU-23 medium including bovine serum albumin in a portable embryo transport incubator at 37°C) or a control group (porcine blastocyst medium in a conventional culture incubator). Thereafter, blastocysts were evaluated for morphology and stained to assess apoptosis straight after the 3 h storage period or after a further 24 h conventional incubation. There was no significant difference between the storage and control group after 3 h storage and the further 24 h conventional incubation for any of the parameters, nor for apoptosis straight after the 3 h storage. Embryos that reached the blastocyst stage at day 5 showed less apoptosis (6.6% vs 10.9%, P = 0.01) and a trend for a higher rate of developmental capacity (70.6% vs 51.5%, P = 0.089) than embryos reaching the blastocyst stage on day 6. In conclusion, in vitro-produced porcine blastocysts can be stored for 3 h at physiological temperature in transportable incubators using a CO2-independent medium without compromising quality.

Study abroad (SA) has long been regarded as a key component of internationalization efforts in higher education and much scholarship has investigated the practices and outcomes of SA from varied perspectives. More recently, scholars have paid growing attention to ways to increase the participation of historically marginalized students in SA, to design SA programs to meet those students’ needs, and to document their experiences abroad. Despite recent scholarship in these areas, relatively little research has employed an equity lens to address research on language-focused SA. This article puts forward language-focused SA as a possible venue to pursue equity and to provide quality education for all students, especially for historically underserved students. More specifically, we address three overarching questions: (1) What theoretical frameworks could be implemented to research SA through an equity lens?; (2) What methodological approaches could inform SA research with an equity lens?; and (3) What topics could be examined to research SA through an equity lens? Drawing on equity as a guiding principle, we discuss relevant research tasks that demonstrate specific ways to address these overarching questions in future research on language-focused SA.

Over the past 2 decades, several categorizations have been proposed for the abnormalities of the aortic root. These schemes have mostly been devoid of input from specialists of congenital cardiac disease. The aim of this review is to provide a classification, from the perspective of these specialists, based on an understanding of normal and abnormal morphogenesis and anatomy, with emphasis placed on the features of clinical and surgical relevance. We contend that the description of the congenitally malformed aortic root is simplified when approached in a fashion that recognizes the normal root to be made up of 3 leaflets, supported by their own sinuses, with the sinuses themselves separated by the interleaflet triangles. The malformed root, usually found in the setting of 3 sinuses, can also be found with 2 sinuses, and very rarely with 4 sinuses. This permits description of trisinuate, bisinuate, and quadrisinuate variants, respectively. This feature then provides the basis for classification of the anatomical and functional number of leaflets present. By offering standardized terms and definitions, we submit that our classification will be suitable for those working in all cardiac specialties, whether pediatric or adult. It is of equal value in the settings of acquired or congenital cardiac disease. Our recommendations will serve to amend and/or add to the existing International Paediatric and Congenital Cardiac Code, along with the Eleventh iteration of the International Classification of Diseases provided by the World Health Organization.
