We undertake a comprehensive investigation into the distribution of in situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with data from the H3 survey. Our analysis reveals that 28% of galaxies demonstrate reasonable agreement with H3, while only 12% exhibit excellent alignment in their profiles, regardless of the specific spatial cut employed to define in situ stars. To uncover the underlying factors contributing to deviations between TNG50 and H3 distributions, we scrutinise correlation coefficients among internal drivers (e.g. virial radius, star formation rate [SFR]) and merger-related parameters (such as the effective mass-ratio, mean distance, average redshift, total number of mergers, average spin-ratio, and maximum spin alignment between merging galaxies). Notably, we identify significant correlations between deviations from observational data and key parameters such as the median slope of virial radius, mean SFR values, and the rate of SFR change across different redshift scans. Furthermore, positive correlations emerge between deviations from observational data and parameters related to galaxy mergers. We validate these correlations using the Random Forest Regression method. Our findings underscore the invaluable insights provided by the H3 survey in unravelling the cosmic history of galaxies akin to the Milky Way, thereby advancing our understanding of galactic evolution and shedding light on the formation and evolution of Milky Way-like galaxies in cosmological simulations.

We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas of the southern hemisphere. We introduce EMU and review its science drivers and key science goals, updated and tailored to the current ASKAP five-year survey plan. The development of the survey strategy and planned sky coverage is presented, along with the operational aspects of the survey and associated data analysis, together with a selection of diagnostics demonstrating the imaging quality and data characteristics. We give a general description of the value-added data pipeline and data products before concluding with a discussion of links to other surveys and projects and an outline of EMU’s legacy value.

Community-engaged research is essential to advance the implementation of evidence-based practices, but engagement quality is rarely assessed. We evaluated community health centers’ (CHCs) experiences partnering with the Implementation Science Center for Cancer Control Equity (ISCCCE) using an online survey of 59 CHC staff. Of 38 respondents (64.4% response rate), most perceived their engagement positively, with over 92% feeling respected by ISCCCE collaborators and perceiving projects as beneficial. Limited staff time and resources were the main challenges identified. This study suggests the utility of gathering feedback to evaluate community research engagement and inform adaptations of research processes to optimize partnership quality.

Film offers untapped potential for making critical interventions in world politics, particularly in ways that harness people’s capacity to narrate stories that creatively empower their communities. Combining International Relations scholarship on visual politics with narrative theory and feminist scholarship on care, this paper presents film as a means of exploring and expressing narrative agency; that is, the power to tell stories that represent people’s experiences in ways that disrupt hegemonic narratives. Dialectics of care and narrative agency are explored in the context of military-to-civilian ‘transition’ in Britain. We argue that the landscape of transition for military veterans is dominated by a preoccupation with employment and economic productivity, resulting in a ‘care deficit’ for veterans leaving the military. Through the Stories in Transition project, which used co-created film to explore narrative agency in the context of three veterans’ charities, we argue that the act of making care visible constitutes a necessary intervention in this transitional landscape. Grounding this intervention within feminist care ethics and the related notion of care aesthetics, we highlight the potential for film to reveal in compelling audio-visual narratives an alternative project of transition which might better sustain life and hope in the aftermath of military service.

In December 2023, the authors screened the film Plan 75, a dystopic meditation on Japan's future as an aging society, with a public audience at Princeton University. The essay offers reflections on the experience of watching the film, the nature of Hayakawa Chie's social commentary and the visual way in which she realizes it, and the present social context for the film's futuristic meditation. The film won the Caméra d'Or Special Mention Prize at the 2023 Cannes Film Festival, and after screenings at global film festivals and the Japan Society of New York, was made available for streaming in the U.S. in late 2023. The film offers contributions to curricula that deal with issues of aging, global capitalism and degrowth, the anthropology and sociology of care, demographic transitions, neoliberal capitalism, and the emergence of a language of individual responsibility in social welfare.

The problem of detecting emergent social structure in small groups is examined in terms of establishing a baseline or expected structure. The standard proposed here is equalitarianism; that is to say, every member is equally likely to interact with every other member. Using information theory, a formal statement of the equalitarian argument is possible. In addition to detecting a deviation by a single group, the structural tendency of several groups assigned to some experimental condition is discussed. This technique is designed for the preliminary analysis of structure; it deals only with the general character of the total structure.

Background: Most individuals with dementia in the UK die in care homes. 70% of these are residential, relying on external healthcare professionals to manage the complex needs. eHealth can help facilitate the delivery of holistic care in care homes, yet adoption has traditionally been faced with resistance. Innovative approaches employing Methods from implementation science are required to promote the uptake of eHealth in care homes.

Aim: To evaluate the feasibility of a theoretically-informed co-designed implementation plan for an eHealth intervention to support holistic assessment and decision making for people with dementia in care homes and their family carers, and to identify opportunities to strengthen it.

Methods: An embedded mixed-Methods study conducted in two residential care homes. Qualitative data comprised non-participant observations of the intervention in use, focus groups and semi-structured interviews with care home staff. Data was analysed using a codebook thematic analysis underpinned by the Normalistion Process Theory. Quantitative data included app usage data and two implementation measures, analysed using descriptive statistics. Patient and public involvement informed development and conduct of the study.

Results: 20 care home staff across two care homes used the intervention with 26 residents. Whilst there was some evidence of adoption, reach within the care home and feasibility of its implementation, usage data indicated that the intervention was largely not utilised as intended. Whilst there was sufficient coherence around the intervention, staff faced barriers related to collective action including workload and incompatibility with practice. Reflexive monitoring was therefore low as individuals could not appraise its impact, which compromised staff cognitive participation. Revisions to the plan related to strategies to provide further staff support, including encouraging family involvement and a more tailored approach to training.

Conclusions: Evaluating feasibility of the implementation plan of the intervention was a vital step in its development. Rapid evaluation and iterative response to barriers to use informed learning and allowed for real- time adjustments to implementation strategies, and a set of updated recommendations for use. Further collaboration on the revised strategies with people living with dementia and their family carers is required.

The terminal Ediacaran Period is signaled worldwide by the first appearance of skeletonizing tubular metazoan fossils, e.g., Cloudina Germs, 1972 and Sinotubulites Chen, Chen, and Qian, 1981. Although recent efforts have focused on evaluating the taxic composition and preservation of such assemblages from the southwestern United States, comparable forms reported in the 1980s from Mexico remain to be re-examined. Here, we reassess the latest Ediacaran skeletal materials from the La Ciénega Formation of the Caborca region in Sonora, Mexico, using a combination of analytical methods: optical microscopy of extracted fossils, thin-section petrography, scanning electron microscopy and energy dispersive X-ray spectroscopy, and X-ray tomographic microscopy. From our examination, we conclude that the La Ciénega hosts a polytaxic assemblage of latest Ediacaran tubular organisms that have been preserved through two taphonomic pathways: coarse silicification and calcareous recrystallization preserving finer details. Further, these fossils show signs that their shells might not have been inflexible or completely mineralized in vivo, and that they might also record tentatively interpreted predation traces in the form of drill holes or puncture marks. This work, along with ongoing efforts around the world, helps to provide a framework for biostratigraphic correlation and possible subdivision of the Ediacaran Period, and further shapes our view of metazoan evolution and ecology in the interval directly preceding the Cambrian explosion.

Luciano Berio’s modernism, which has fallen off the critical radar since the composer’s death, is not typically tied to extroverted political statements, and so does not easily allow for the fashionable (liberal) equation of aesthetic radicalism with political radicalism. On the contrary, Berio’s musical output is perhaps instructive precisely as a negative case study of the link between political and aesthetic radicalisms. Such will be the gambit of this article, which will consider the engagement with contemporary ideas of ‘openness’ and practices of phenomenology in works from the early 1960s, like Passaggio (1962) and Epifanie (1963), to illuminate Berio’s relationship to the so-called neoavanguardia, a cultural movement which emerged in the 1950s and 1960s as part of a withdrawal from the cultural–political activism associated within Italy’s leftist intelligentsia.

Two-line ferrihydrite is an important adsorbent of many toxics in natural and anthropogenic systems; however, the specific structural sites responsible for the high adsorption capacity are not well understood. A combination of chemical and spectroscopic techniques have been employed in this study to gain further insight into the structural nature of sites at the ferrihydrite surface. The kinetics of iron isotopic exchange demonstrated that there are at least two types of iron sites in ferrihydrite. One population of sites, referred to as labile sites, approached iron isotopic equilibrium within 24 hr in 59Fe-NTA solutions, while the second population of sites, referred to as non-labile, exhibited a much slower rate of isotopic exchange. Adsorbed arsenate reduced the degree of exchange by labile sites, indicating that the anion blocked or greatly inhibited the rate of exchange of these sites. Mössbauer spectra were collected from a variety of samples including 56Fe-ferrihydrite samples with 57Fe in labile sites, samples containing 57Fe throughout the structure, and samples with 57Fe in non-labile sites. The spectra showed characteristic broad doublets signifying poor structural order. Refined fits of the spectra indicated that labile sites have larger quadrupole splitting, hence more local distortion, than non-labile sites. In all cases, the spectra demonstrated some degree of asymmetry, indicating a distribution of Fe environments in ferrihydrite. Overall spectral findings, combined with recent EXAFS results (Waychunas et al., 1993), indicate that labile sites likely are more reactive (with respect to iron isotopic exchange) because they have fewer neighboring Fe octahedra and are therefore bound less strongly to the ferrihydrite structure. The labile population of sites probably is composed of end sites of the dioctahedral chain structure of 2-line ferrihydrite, which is a subset of the entire population of surface sites. Mössbauer spectra of samples containing adsorbed arsenate indicated that the anion may slightly decrease the distortion of labile sites and stabilized the structure as a whole by bidentate bonding.
