In an era of intergenerational inequality and political polarization, what might make older voters support greater government spending on the young? Building on literature concerning family-centric political preferences, we theorize that older voters support pro-youth policies and vote for pro-youth parties when they perceive younger relatives to be struggling financially due to emotional bonds and shared risks. Using a large, original survey of British adults, we find that negative evaluations of the financial wellbeing of one’s younger relatives – which are linked to their objective economic assets – are associated with support and prioritization of state investment in education, childcare and housing. They are also associated with opposition to the incumbent Conservatives, in a relationship mediated by assessments that this party represents young people badly. The implications are important for understanding how emotional connections, more than self-interest, sensitize voters to family-wide economic hardship and help produce ‘family-centric’ economic voting.

The 2019 UK General Election had seismic consequences for British politics. After three years of political turmoil following the 2016 referendum on Britain’s membership of the European Union (EU), the 2019 election marked a victory for the Leave side of the Brexit debate, putting to rest questions of a second referendum and any chance of Parliament blocking the Withdrawal Bill. The United Kingdom left the EU on January 31, 2020. Although there were clear consequences for Britain’s EU membership, there is debate about whether 2019 was a “Brexit election” (Prosser 2020)—even a critical election (Green 2021)—or the continuation of long-term realignments in British politics (Cutts et al. 2020; Jennings and Stoker 2017). By most accounts, Brexit dominated the 2019 election as a political issue, but whether this represents a key moment in a process of realignment of voters in Britain remains to be seen.

Despite a global interest in the musical experiences of young children, the everyday musical lives of young New Zealanders remain unexamined. Using data collected through the Growing Up in New Zealand longitudinal study, we explore the early musical experiences of approximately 6,800 infants and toddlers. Data collected from the primary caregivers and their partners pre-birth, when the children were 9 months old, and 2 years old are used to explore five areas: parental singing; active musical play; music listening; involvement in music groups; and participation in wider cultural events. Musical engagement is analysed with respect to various child, parental and family characteristics, including parental education, socio-economic status, and parental knowledge of and appreciation for the arts. The results provide a holistic description of the musical environments of young children in Aotearoa New Zealand.

OBJECTIVES/GOALS: Pancreatic cysts are comprised of both precancerous mucinous lesions and non-mucinous lesions with minimal malignant potential. Our goal is to improve our ability to classify the type of cyst using a combination of novel radiomic features and cyst fluid proteolytic activity. METHODS/STUDY POPULATION: Preoperative pancreatic protocol CT images from 30 patients with proteolytic assay characterization, followed by surgical resection with a pathologically confirmed pancreatic cyst diagnosis between 2016-2019 will be used in this study. We will contour images using the widely available software 3D Slicer, and extract radiomic features using IBEX software. We will analyze area under the ROC curves to identify the radiomic features that best differentiate mucinous from non-mucinous cysts, and identify features to be cross validated. The predictive ability of identified radiomic features combined with proteolytic assay will be determined by performing multiple logistic regression analysis and comparing AUROC analysis. We will determine sensitivity and specificity for individual, as well as combinations of, analytes to determine the optimal classifier. RESULTS/ANTICIPATED RESULTS: We anticipate that the predictive ability, sensitivity, and specificity of utilizing radiomic features combined with proteolytic assay data will exceed the performance of any individual test. DISCUSSION/SIGNIFICANCE OF IMPACT: This work is designed to provide a predictive radiomic model that will enable us to better identify mucinous cysts that require further evaluation, and potentially prevent unnecessary surgery in other patients. Ultimately, we would like to improve the accuracy of noninvasive radiographic evaluation using radiomic markers.

The scarcity of Romano-British human remains from north-west England has hindered understanding of burial practice in this region. Here, we report on the excavation of human and non-human animal remains1 and material culture from Dog Hole Cave, Haverbrack. Foetal and neonatal infants had been interred alongside a horse burial and puppies, lambs, calves and piglets in the very latest Iron Age to early Romano-British period, while the mid- to late Roman period is characterised by burials of older individuals with copper-alloy jewellery and beads. This material culture is more characteristic of urban sites, while isotope analysis indicates that the later individuals were largely from the local area. We discuss these results in terms of burial ritual in Cumbria and rural acculturation. Supplementary material is available online (https://doi.org/10.1017/S0068113X20000136), and contains further information about the site and excavations, small finds, zooarchaeology, human osteology, site taphonomy, the palaeoenvironment, isotope methods and analysis, and finds listed in Benson and Bland 1963.

Isotope ratios of tooth enamel from ten Early Neolithic individuals buried in a long cairn at Whitwell in central England were measured to determine where they sourced their childhood diet. Five individuals have low Sr concentrations (11–66 ppm) and high 87Sr/86Sr ratios (0.7164–0.7212). Three individuals have relatively low 87Sr/86Sr ratios (0.712–0.711) and Sr concentrations ranging between 54 and 109 ppm. Two individuals have strontium isotope values that bridge the gap between the isotope compositions of these two groups. The high 87Sr/86Sr values are rare in human enamel and exclude sources within the biosphere of central England. Oxygen isotope values are comparable to those found within human archaeological populations buried in temperate regions of Europe. The strontium isotope results should be interpreted in the context of other evidence for migration from northern France to Britain during the Early Neolithic.

The nature of landscape use and residence patterns during the British earlier Neolithic has often been debated. Here we use strontium and oxygen isotope analysis of tooth enamel, from individuals buried at the Hambledon Hill causewayed enclosure monument complex in Dorset, England to evaluate patterns of landscape use during the earlier Neolithic. Previous analysis suggests that a significant proportion of the artefacts found at the site may originate from lithology of Eocene and Upper to Middle Jurassic age that the enclosures overlook to the immediate west and south. The excavators therefore argued that the sector of landscape visible from Hambledon Hill provides an approximate index for the catchment occupied by the communities that it served. Most of the burial population exhibit isotope ratios that could be consistent with this argument. Connections between Hambledon Hill and regions much further afield are also hypothesised, based on the presence of artefacts within the assemblage that could have been sourced from lithology in Somerset, Devon, and Cornwall in south-west England. However, few of the sampled individuals have strontium isotope ratios consistent with having obtained the majority of their diet from such areas during childhood. The individuals who exhibit the highest strontium isotope ratios are all adult males, whom the excavators suggest to have died during one or more episodes of conflict, following the burning and destruction of surrounding defensive outworks built during the 36th century bc. At least one of these individuals, who was found with an arrowhead amongst his ribs, did not obtain his childhood diet locally and has 87Sr/86Sr values that could be comparable to those bioavailable in the south-west peninsula.

Considerable debate persists concerning the origins of those involved in the adventus Saxonum: the arrival of Germanic peoples in Britain during the fifth century AD. This question was investigated using oxygen and strontium isotope ratios obtained from archaeological dental samples from individuals in the ‘Migration Period’ cemetery, Ringlemere, Kent (n = 7) and three continental European sites (n = 17). Results demonstrated that strontium alone is unable to distinguish between individuals from south-east England and north-west Europe. Although 87Sr/86Sr values from Ringlemere fell within local biosphere parameters and suggest a spatially and temporally related group, δ18O values were inconsistent with origins in eastern England or on the North German plain. Results from the European sites negate past climate change as an explanation. It is possible that culturally mediated behaviour has obscured geographical relationships. Further work to characterize water sources and human δ18O values in the putative European homelands is required.

A new procedure is described in which combined lead and strontium isotope analysis of archaeological human dental tissues can be used to comment on the lifetime movements of individuals. A case study is presented of four Neolithic burials – an adult female and three juveniles – from a shared burial pit excavated at Monkton-up-Wimbourne, Dorset. It is demonstrated that the adult's place of origin was at least 80km to the north-west in the area of the Mendips. It is also shown that all three juveniles moved over significant distances during their lives.

The appearance of the distinctive ‘Beaker package’ marks an important horizon in British prehistory, but was it associated with immigrants to Britain or with indigenous converts? Analysis of the skeletal remains of 264 individuals from the British Chalcolithic–Early Bronze Age is revealing new information about the diet, migration and mobility of those buried with Beaker pottery and related material. Results indicate a considerable degree of mobility between childhood and death, but mostly within Britain rather than from Europe. Both migration and emulation appear to have had an important role in the adoption and spread of the Beaker package.

We use high-resolution Keck, VLT, or Hubble Space Telescope spectra of background quasars to examine the kinematic properties of the multiphase, metal-enriched circumgalactic medium in the outskirts of galaxies at 0.08 < zgal < 1.0, focusing on the low-ionization Mgii and high-ionization Ovi doublets. The absorption kinematics of low-ionization gas in the circumgalactic medium depend strongly on the star formation activity and the location about the host galaxy, where the largest velocity dispersions are associated with blue, face-on galaxies probed along the minor axis. Conversely, high-ionization gas kinematics are independent of galaxy star formation activity and orientation.

A detailed morphological study of over 2,500 Middle Ordovician (Black Riveran) lophospirid archaeogastropods from the lower half of the Platteville Formation (Pecatonica Member and Mifflin Submember of the McGregor Member), principally as it is exposed in southern Wisconsin, has permitted the definition of five species of Lophospira. Lophospira perangulata (Hall), L. milleri (Hall), L. serrulata (Salter), L. helicteres (Salter), and L. delicata (n. sp.) are preserved throughout a three-meter interval of fine-grained, heavily bioturbated carbonates, now dolomitized. Deposition took place on a broad, shallow tropical shelf, which was characterized by low rates of deposition and low physical energy. The sampled interval represents about 500,000 years. The benthic marine invertebrate fauna is well preserved, diverse, and characteristic of an environment of normal marine salinity.

Of the five Lophospira species, only one, L. perangulata, has been positively identified in older strata (late Whiterockian, eastern North America). The other four species were endemic to the interior seas, and apparently at least two of these, L. serrulata and L. helicteres, did not survive into post-Platteville (post-Black Riveran) environments. Changes in the proportions of lophospirid species from the Pecatonica into the Mifflin strata probably reflect subtle changes in the distribution of carbonate shelf habitats but no major alteration in the kinds of habitats available for colonization.
