Foregrounding the ageing self: a duoethnographic account of growing older as a gerontologist and educator
Authors: Hostetler Andrew J. , Weil Joyce 
Published: February 2023

AbstractAlthough ageing is personally relevant to many if not most gerontologists, a reflexive perspective is largely absent from gerontological scholarship. This paper employs duoethnography, a variant of autoethnography, to explore how experiences related to growing older have informed the authors' teaching and scholarship in the field of ageing. Duoethnography involves putting two autoethnographies into conversation, promoting dynamic self-understandings and generating new insights through dialogue. The co-authors first reflected on their journeys to date in the field, including on how the personification of ageing has shifted our perspective. Then we shared our narratives and made some initial revisions based on each other's feedback. Next, we collaboratively identified and discussed three broad, connective themes: the differing yet central role of gender in our narratives, teaching and generativity, and the pedagogical and personal challenges associated with ageism. Our reflections and dialogue deepened our understanding of these issues central to studying and teaching about ageing. The kind of reflective practice that we model could be a vital resource for bridging the gap between theory and practice, researcher and researched.
‘Ways of being’ in the domestic garden for people living with dementia: doing, sensing and playing
Authors: Buse Christina , Balmer Andrew , Keady John , Nettleton Sarah , Swift Sarah 
Published: February 2023

AbstractDomestic gardens represent a site for enacting embodied identity and social relationships in later life, and negotiating tensions between continuity and change. In the context of dementia, domestic gardens have significant implications for ‘living well’ at home, and for wider discussions around embodiment, relational selfhood and agency. Yet previous studies exploring dementia and gardens have predominantly focused on care home or community contexts. In light of this, the paper explores the role of domestic gardens in the everyday lives of people living with dementia and their households, using qualitative, creative methods. This includes filmed walking interviews and garden tours, diaries and sketch methods, involving repeat visits with six households in England. Findings are organised thematically in relation to different ‘ways of being’ in the garden: working in and doing the garden; being in and sensing; and playing, empowerment and agency. These different ‘ways of being’ are situated within relationships with household members, neighbours and non-human actors, including pets, wildlife and the materiality of the garden. Garden practices illustrate continuity, situated within embodied biographies and habitus. However, identities, practices and gardens are also subject to ongoing readjustment and reconstruction. The conclusion discusses implications for extending literature on gardens and later life, describing how social and material relationships in domestic gardens are renegotiated in the context of dementia, while highlighting opportunities for ‘play’, active sensing and agency. We also explore contributions to understandings of dementia, home and place, and implications for garden design and care practice.

AbstractPrevious studies have found negative ageing narratives in the media during the COVID-19 pandemic. However, few have focused on compassionate ageism and how the news responded to the progression of the COVID-19 pandemic. We investigated (a) media themes of negative and compassionate ageism and (b) their relationships with COVID-19 parameters and the public health response. The sample included 1,197 articles relevant to COVID-19 and older people in Hong Kong published between January and December 2020. We used thematic analysis to identify themes from the news articles and structural equation modelling to explore these themes' relationship with the number of older people infected, effective reproduction number, number of COVID-19 deaths and public health response parallel in time. Pandemic-related variables were lagged for a day – the time needed to be reflected in the news. Two negative ageism themes portrayed older people as vulnerable to COVID-19 but counterproductive in combating the pandemic. Two compassionate ageism themes depicted older people as a homogenous group of passive assistance recipients. The theme blaming older people was associated with the number of confirmed infections (β = 0.418, p = 0.002) but vulnerability of older people was not associated with pandemic-related variables. The theme helping older people was negatively associated with the percentage of older people in confirmed infections (β = −0.155, p = 0.019). The theme resources available was negatively associated with confirmed infections (β = −0.342, p < 0.001) but positively associated with the Containment and Health Index (β = 0.217, p = 0.005). Findings suggested that negative and compassionate ageism were translated into narratives about older people in the media as the pandemic evolved but did not address the actual risk they faced. Media professionals should be aware of the potential negative and compassionate ageism prompted by the news agenda and promote adequate health behaviours and responses.
Care arrangements between family and state – developing hybrid scripts of ageing in a context of migration
Authors: Liversage Anika 
Published: February 2023

AbstractDue to demographic developments, the number of immigrant families with older members is growing across Western Europe. Poised between the different approaches to care in their countries of origin and destination, such families are treading new ground as they negotiate support for older family members. Based on semi-structured interviews with 26 older and younger family members from 20 Turkish immigrant families in Denmark, this article investigates the broad variation in how these families approach caring for older people. At one end of the scale, some families (re)create a traditional Turkish approach to care in which three generations live together and the daughter-in-law is the main care provider. At the other end of the scale, some families follow the Danish approach in which families rely on public care provision. In between these two poles, many families devise a variety of care solutions for their older members that often rely on considerable support by family. Utilising Cati Coe's concept of care-scription, the analysis shows how families negotiate – and sometimes struggle over – who will shoulder which tasks. In the post-migration context, daughters-in-law are often able to retreat from their traditional role of care provider, which in turn increases expectations of daughters' care provisions. In Denmark, which is a relatively gender-equal society, Turkish daughters may seek to make their brothers take on a greater role in the provision of care for their parents, and in some families, the children also turn towards public care provisions to share the burden of parental care. Resistance from older parents may, however, short-circuit this strategy. Overall, the study points both to the difficulties faced by older immigrants with limited host-country language proficiency when utilising public European care provisions and to the complex and unsettled nature of care provisions in immigrant families in Europe today.

Abstract
The resurgence and outbreaks of mumps occur frequently in many countries worldwide in recent years, even in countries with high vaccination coverage. In this study, a descriptive and spatiotemporal clustering analysis at the township level was conducted to explore the dynamic spatiotemporal aggregation and epidemiological characteristics of mumps in Wuhan. During 2005 and 2019, there were 40 685 cases reported in Wuhan, with an average annual morbidity of 28.11 per 100 000 populations. The morbidity showed a fluctuating tendency, and peaked in 2010 and 2018. Bimodal seasonality was found, with a large peak between May and July, and a mild peak from November to January in the following year. Male students aged 5–9-year-old were the main risk group of mumps infection. Significant global spatial auto-correlation was detected except in 2007, 2009 and 2015. The spatial and temporal scan statistics indicated that the hot-spots mainly located at the western and southern areas of Wuhan with variations almost every year. Our findings could assist the public health authorities to develop and improve targeted health strategies, and allocate health resources rationally.
Extensive protected area coverage and an updated global population estimate for the Endangered Madagascar Serpent-eagleEutriorchis astur

Published: February 2023

SummaryKnowledge gaps regarding distribution, habitat associations, and population size for rare and threatened range-restricted taxa lead to uncertainty in directing conservation action. Quantifying range metrics and species–habitat associations using Species Distribution Models (SDMs) with remote-sensing habitat data can overcome these setbacks by establishing baseline estimates for biological parameters critical for conservation assessments. Area of Habitat (AOH) is a new range metric recently developed by the International Union for Conservation of Nature (IUCN) Red List. AOH seeks to quantify inferred habitat within a species’ range to inform extinction risk assessments. Here, we used SDMs correlating occurrences with remote-sensing covariates to calculate a first estimate of AOH for the Endangered Madagascar Serpent-eagleEutriorchis astur, and then updated additional IUCN range metrics and the current global population estimate. From these baselines we then conducted a gap analysis assessing protected area coverage. Our continuous SDM had robust predictive performance (Continuous Boyce Index = 0.835) and when reclassified to a binary model estimated an AOH = 30,121 km2, 13% less than the current IUCN range map. We estimated a global population of 533 mature individuals derived from the Madagascar Serpent-eagle AOH metric, which was within current IUCN population estimates. The current protected area network covered 95% of AOH, with the binary model identifying three additional key habitat areas as new protected area designations to fully protect Madagascar Serpent-eagle habitat. Our results demonstrated that correlating presence-only occurrences with remote-sensing habitat covariates can fill knowledge gaps useful for informing conservation action. Applying this spatial information to conservation planning would ensure almost full protected area coverage for this endangered raptor. For tropical forest habitat specialists, we recommend that potential predictors derived from remote sensing, such as vegetation indices and biophysical measures, are considered as covariates, along with other variables including climate and topography.
Supplementation of culture medium with quercetin improves mouse blastocyst quality and increases the expression of HIF-1α protein

Published: February 2023

SummaryRegarding the low number of embryos that reach the blastocyst stage when cultured in vitro, this study aimed to evaluate the effects of quercetin on pre-implantation mouse (Mus musculus) embryos obtained using in vitro fertilization, especially during the passage from morula to blastocyst. Furthermore, we studied whether quercetin also affected the expression of hypoxia-inducible factor 1α (HIF-1α). The culture medium for the embryos was supplemented with quercetin, for long or short periods of time, and then the development potential, total cell number, apoptosis rates and expression of HIF-1α were studied to determine the effect of quercetin. Embryos failed to develop when cultured for long periods of time with quercetin, implying the possible toxic effects of this, alternatively antioxidant, compound. However, a short culture from morula to blastocyst significantly improved the development potential of in vitro produced embryos, increasing the final total cell number and reducing the apoptosis rate, observing similar results to those embryos cultured in low-oxygen concentrations or developed in utero. Furthermore, in embryos treated with quercetin for 2 or 4 h we found an increase in HIF-1α compared with untreated embryos. This work could imply a way to use quercetin in fertility clinics to improve the production of healthy blastocysts and, consequently, increase the success rates in assisted reproduction techniques.
On being Orthodox renouncers: theYuktidīpikā's establishment of the Sāṅkhya mode of life (Sannyāsa) in the name of the Veda
Authors: Ham Hyoung Seok 
Published: February 2023

AbstractUnlike other commentaries on theSāṅkhyakārikā, theYuktidīpikā(circasixth to eighth centuries) problematised the Sāṅkhya tradition's equivocal attitudes toward the Veda. While submitting itself to the authority of the Veda, theYuktidīpikā's commentary onSāṅkhyakārikā2 illustrates how Sāṅkhya thinkers of the post-Gupta period safeguarded the identity of Brahmin renouncers. Aligning its doctrine with the Upaniṣad, the end of the Veda, theYuktidīpikālaunched a Sāṅkhya navigation of the central concern of Indian intellectuals, Vedic hermeneutics, and attempted to secure Sāṅkhya's place within Vedic orthodoxy. This article discusses theYuktidīpikā's strategy for surviving the peer pressure of Vedic ritualists, as represented by the Mīmāṃsakas, while maintaining Sāṅkhya superiority by exploiting the inner division within the Veda.
Exploring the neutron star zoo: An observational review
Authors: Borghese Alice 
Published: February 2023

AbstractNeutron stars have shown diverse characteristics, leading us to classify them into different classes. In this proceeding, I review the observational properties of isolated neutron stars: from magnetars, the strongest magnets we know of, to central compact objects, the so-called anti-magnetars, stopping by the rotation-powered pulsars and X-ray dim isolated neutron stars. Finally, I highlight a few sources that have exhibited features straddling those of different groups, blurring the apparent diversity of the neutron star zoo.
Inferring the dense nuclear matter equation of state with neutron star tides
Authors: Pnigouras Pantelis , Andersson Nils 
Published: February 2023

AbstractDuring the late stages of a neutron star binary inspiral finite-size effects come into play, with the tidal deformability of the supranuclear density matter leaving an imprint on the gravitational-wave signal. As demonstrated in the case of GW170817—the first direct detection of gravitational waves from a neutron star binary—this can lead to strong constraints on the neutron star equation of state. As detectors become more sensitive, effects which may have a smaller influence on the neutron star tidal deformability need to be taken into consideration. Dynamical effects, such as oscillation mode resonances triggered by the orbital motion, have been shown to contribute to the tidal deformability, especially close to the neutron star coalesence. We calculate the contribution of the various stellar oscillation modes to the tidal deformability and demonstrate the (anticipated) dominance of the fundamental mode, showing what the impact of the matter composition is on the tidal deformability.
Are hypermassive neutron stars stable against a prompt collapse?
Authors: Szewczyk Paweł , Gondek-Rosińska Dorota , Kolasa Kamil , Mehta Parita 
Published: February 2023

AbstractDifferential rotation in neutron stars allows for significantly larger masses than rigid rotation. Some of those hypermassive objects are, however, unstable and collapse to a black hole immediately after formation. Yet, the exact threshold of dynamical stability is still unknown.In our work we explore the limits on masses of neutron stars with various degrees of differential rotation which could be stable against a prompt collapse to a black hole by using turning-point (j-constant) criterion. We considered both spheroidal and quasi-toroidal differentially rotating neutron stars described by the polytropic equation of state. We find that massive configurations could be temporarily stabilized by differential rotation. Such objects are important sources of gravitational waves. Our results are a starting point for more detailed studies of stability using hydrodynamical codes.
The Magnetar Connection

AbstractWe investigate the combined evolution of the dipolar surface magnetic field (Bs) and the spin-period (Ps) of known Magnetars and high magnetic field (
$${{\rm{B}}_s} \mathbin{\lower.3ex\hbox{$\buildrel>\over {\smash{\scriptstyle\sim}\vphantom{_x}}$}} {10^{13}}{\rm{G}}$$
) radio pulsars. We study the long term behaviour of these objects assuming a simple Ohmic dissipation of the magnetic field. Identifying the regions (in the Ps-Bs plane) in which these neutron stars would likely move into, before crossing the death-line to enter the pulsar graveyard, we comment upon the possible connection between the Magnetars and other classes of neutron stars.
Advancing Computational Methods to Understand the Dynamics of Ejection, Accretion, Winds, and Jets in Binary Neutron Star Mergers
Authors: Lopez Armengol Federico G. ,   Compact-Binaries Collaboration
Published: February 2023

AbstractWe introduce the HandOff, a set of computational tools to transfer general relativistic magnetohydrodynamic and spacetime data from the numerical code IllinoisGRMHD to Harm3d. While the former simulates binary neutron star (BNS) mergers in full dynamical General Relativity, the latter specializes in modeling accretion disks around black holes (BH) over long timescales. The HandOff, then, enables us to transfer the outcome of BNS mergers after BH formation from IllinoisGRMHD to Harm3d and to evolve the post-merger system efficiently over long timescales. We show our latest results in this respect, for matter modeled as a magnetized ideal-fluid, and discuss our future plans which involve incorporating advanced equations of state and neutrino physics into BNS simulations using the HandOff approach.
Modelling the deformability of magnetized neutron stars in the light of future continuous gravitational waves detection
Authors: Bucciantini Niccolò , Soldateschi Jacopo 
Published: February 2023

AbstractNeutron stars are known to host extremely powerful magnetic fields. Among other effects, one of the consequences of harboring such fields is the deformation of the neutron star structure, leading, together with rotation, to the emission of continuous gravitational waves (CGWs). We present an extensive numerical study of magnetized neutron stars in GR with a large variety of different Equations of State (EoSs) and show that it is possible to find simple relations between the magnetic deformation of a neutron star, its mass and radius, that are mostly independent on the EoS or magnetic configuration. We discuss how these relations can be used in conjunction with possible future CGWs detection to set constrains on the EoS and magnetic configurations of NSs (e.g. the presence of a superconducting phase). By carrying out a population synthesis, we estimate the possible CGWs detectability of galactic millisecond pulsars, with third generation GW detectors.
Sitting at the Same Table: a cross-disciplinary ‘constitutional-institutionalist’ approach to the study of constitutions
Authors: Passchier Reijer , Stremler Maarten 
Published: February 2023

AbstractThis article presents a cross-disciplinary approach to the study of constitutions: ‘constitutional institutionalism’. Conventional approaches in law, philosophy or political science tend to reduce constitutions either to their formal, factual or ideal aspects. The constitutional-institutionalist approach, by contrast, seeks to integrate these aspects into a more general perspective by focusing on the dynamic interplay between constitutional actors and constitutional norms. It understands constitutional norms as binding institutions that shape and constrain political action, but never fully determine it. Constitutional institutionalism furthermore asserts that constitutional norms, whatever form they take, only have meaning in relation to other constitutional norms as well as to constitutional actors, who impose meaning on these norms. Therefore, constitutional phenomena ultimately require interpretive explanations. This article concludes with a brief constitutional-institutionalist research agenda.
Characterising the cave bear Ursus spelaeus Rosenmüller by ZooMS: a review of peptide mass fingerprinting markers

ABSTRACTIn the last decade, the identification of bone fragments by peptide mass fingerprinting or zooarchaeology by mass spectrometry is developing as a powerful tool in Quaternary palaeontology. The sequence of amino acids that make up the bone collagen molecule shows slight variations between taxa, which can be studied by mass spectrometry for taxonomic purposes. This requires reference databases that allow peptide identification. Although the cave bear (Ursus spelaeus Rosenmüller, 1794) is a common component in many European Pleistocene cave sites, no peptide fingerprint taxonomic study has paid special attention to this species up to now. For peptide markers in Ursidae, the most recent proposal is based on collagen obtained from a modern brown bear sample. In this work we attempt to cover this gap by studying bone collagen of cave and brown bear samples from different origins and different chronology, applying matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI TOF). We also performed an in-silico study of ursid bone collagen sequences published in databases. In our results we detected some discrepancies between the peptides obtained from both in silico and MALDI TOF analysis of fossil collagen and those published in the literature, in which we conclude that there are some misidentified peptides. The identification of skeletal remains by means of their peptide fingerprint is proving to be a powerful tool in palaeontology, which will bear greater fruit once the limitations of a technique that is in its initial stages have been overcome.
