The introduction of new legislation in 2006 brought about changes to the way citizenship applications were considered in the UK. Over the intervening years, several hundred children born in the UK have been denied British citizenship as a result of changes to the ‘good character’ requirement in the legislation – namely its extension to cover all those aged 10 years or older applying for citizenship, including individuals who were born in the UK. As a result of the formulaic way in which this requirement is assessed, citizenship can be denied on the basis of historical patterns of behaviour or offending from childhood. This article will consider whether the current approach to assessment of character in the context of applications for British citizenship is meaningful or appropriate, given developments in our understanding of normative psychological and neurological development and also the impact of psychosocial adversity, trauma, and broader psychopathological or neurodevelopmental conditions.

The COVID-19 pandemic in Australia has profoundly affected older adults, particularly in the state of Victoria, which experienced strict lockdown restrictions six times since the pandemic began in 2020; totalling 245 days over three years. This study explored the experiences of older adults living in retirement villages during the first three lockdowns in Victoria from March 2020 to February 2021. We draw on the concept of the ‘third age’ to explore how residents’ post-retirement social and lifestyle aspirations were disrupted by the pandemic and associated lockdowns. In-depth qualitative interviews were conducted with 14 residents during January and February 2021. All data were analysed using thematic mapping. Five key themes were identified: (1) benefits and frustrations of retirement village living during a pandemic; (2) the loss of amenities and activities; (3) heightened loneliness and social isolation; (4) reaching out to others; and (5) variable experiences of operators’ response. Although the COVID-19 pandemic has highlighted short-term and long-term issues around social isolation and the management of retirement villages, it has also demonstrated the resilience of residents and the strength of community ties and relationships. Retirement villages are promoted as age-friendly environments that enable an active and healthy post-retirement lifestyle. Yet our findings reveal heterogeneity within village populations. When services closed during lockdowns, this revealed a tension between the policy assumption that retirement villages are a housing consumption choice, and the unmet needs of those residents who depend on village services for day-to-day functioning.

Research investigating social anxiety and the impacts on romantic relationships remains scarce. An online questionnaire examining romantic relationship status, social anxiety and depression symptomology, relationship satisfaction, and several relationship processes was completed by 444 adults. Individuals with higher social anxiety were less likely to be in romantic relationships. For the 188 adults in our sample in current relationships, relationship satisfaction was not influenced by social anxiety when controlling for depression. Although it was proposed that self-disclosure, social support, trust, and conflict initiation might influence romantic relationship satisfaction, none of these mechanisms interacted with social anxiety to explain additional variance in relationship satisfaction. These findings indicate that depression symptomology may be a treatment target for socially anxious individuals wishing to improve romantic relationship satisfaction.

High-throughput grain mapping with sub-nanometer spatial resolution is demonstrated using scanning nanobeam electron diffraction (also known as 4D scanning transmission electron microscopy, or 4D-STEM) combined with high-speed direct-electron detection. An electron probe size down to 0.5 nm in diameter is used and the sample investigated is a gold–palladium nanoparticle catalyst. Computational analysis of the 4D-STEM data sets is performed using a disk registration algorithm to identify the diffraction peaks followed by feature learning to map the individual grains. Two unsupervised feature learning techniques are compared: principal component analysis (PCA) and non-negative matrix factorization (NNMF). The characteristics of the PCA versus NNMF output are compared and the potential of the 4D-STEM approach for statistical analysis of grain orientations at high spatial resolution is discussed.

Despite enormous strides in our field with respect to patient care, there has been surprisingly limited dialogue on how to train and educate the next generation of congenital cardiologists. This paper reviews the current status of training and evolving developments in medical education pertinent to congenital cardiology. The adoption of competency-based medical education has been lauded as a robust framework for contemporary medical education over the last two decades. However, inconsistencies in frameworks across different jurisdictions remain, and bridging gaps between competency frameworks and clinical practice has proved challenging. Entrustable professional activities have been proposed as a solution, but integration of such activities into busy clinical cardiology practices will present its own challenges. Consequently, this pivot towards a more structured approach to medical education necessitates the widespread availability of appropriately trained medical educationalists, a development that will better inform curriculum development, instructional design, and assessment. Differentiation between superficial and deep learning, the vital role of rich formative feedback and coaching, should guide our trainees to become self-regulated learners, capable of critical reasoning yet retaining an awareness of uncertainty and ambiguity. Furthermore, disruptive innovations such as “technology enhanced learning” may be leveraged to improve education, especially for trainees from low- and middle-income countries. Each of these initiatives will require resources, widespread advocacy and raised awareness, and publication of supporting data, and so it is especially gratifying that Cardiology in the Young has fostered a progressive approach, agreeing to publish one or two articles in each journal issue in this domain.

Carbonatites are enriched in critical raw materials such as the rare-earth elements (REE), niobium, fluorspar and phosphate. A better understanding of their fluid regimes will improve our knowledge of how to target and exploit economic deposits. This study shows that multiple fluid phases penetrated the surrounding fenite aureole during carbonatite emplacement at Chilwa Island, Malawi. The first alkaline fluids formed the main fenite assemblage and later microscopic vein networks contain the minerals of potential economic interest such as pyrochlore in high-grade fenite and rare-earth minerals throughout the aureole. Seventeen samples of fenite rock from the metasomatic aureole around the Chilwa Island carbonatite complex were chosen for study. In addition to the main fenite assemblage of feldspar and aegirine ± arfvedsonite, riebeckite and richterite, the fenite contains micro-mineral assemblages including apatite, ilmenite, rutile, magnetite, zircon, rare-earth minerals and pyrochlore in vein networks. Petrography using a scanning electron microscope in energy-dispersive spectroscopy mode showed that the rare-earth minerals (monazite, bastnäsite and parisite) formed later than the fenite feldspar, aegirine and apatite and provide evidence of REE mobility into all grades of fenite. Fenite apatite has a distinct negative Eu anomaly (determined by laser ablation inductively coupled plasma mass spectrometry) that is rare in carbonatite-associated rocks and interpreted as related to pre-crystallization of plagioclase and co-crystallization with K-feldspar in the fenite. The fenite minerals have consistently higher mid REE/light REE ratios (La/Sm ≈ 1.3 monazite, ≈ 1.9 bastnäsite, ≈ 1.2 parisite) than their counterparts in the carbonatites (La/Sm ≈ 2.5 monazite, ≈ 4.2 bastnäsite, ≈ 3.4 parisite). Quartz in the low- and medium-grade fenite hosts fluid inclusions, typically a few micrometres in diameter, secondary and extremely heterogeneous. Single phase, 2- and 3-phase, single solid and multi solid-bearing examples are present, with 2-phase the most abundant. Calcite, nahcolite, burbankite and baryte were found in the inclusions. Decrepitation of inclusions occurred at ∼200°C before homogenization but melting-temperature data indicate that the inclusions contain relatively pure CO2. A minimum salinity of ∼24 wt.% NaCl equivalent was determined. Among the trace elements in whole-rock analyses, enrichment in Ba, Mo, Nb, Pb, Sr, Th and Y and depletion in Co, Hf and V are common to carbonatite and fenite but enrichment in carbonatitic type elements (Ba, Nb, Sr, Th, Yand REE) generally increases towards the inner parts of the aureole. A schematic model contains multiple fluid events, related to first and second boiling of the magma, accompanying intrusion of the carbonatites at Chilwa Island, each contributing to the mineralogy and chemistry of the fenite. The presence of distinct rare-earth mineral microassemblages in fenite at some distance from carbonatite could be developed as an exploration indicator of REE enrichment.

Doubt is a promising subject of inquiry for historians. Its initial definition in the Oxford English Dictionary reads ‘[t]he (subjective) state of uncertainty with regard to the truth or reality of anything; undecidedness of belief or opinion’, which might be advocated as a necessary mindset for any historically inclined investigator embarking on research. Although not always articulated, historians constantly face the ‘state of uncertainty’ of knowledge of the past and the continuous need, therefore, to test the evidence. The compilers of the OED then, perhaps unwittingly, underscore the particular relevance of ‘doubt’ as a subject for ecclesiastical historians by further defining it as ‘uncertainty as to the truth of Christianity or some other religious belief or doctrine’. The prominent placing of this second definition acknowledges the reality that doubts about religious ideas and individual doctrines, if not faith itself, have long been conspicuous in human language, and not just when speaking about Christianity. Nonetheless, the means and the consequences of communicating doubt depend on, and are intensely revealing of, changing historical circumstance.

This essay focuses on the figure of John the Baptist in prison and the question he sent his disciples to ask Christ: was he ‘the one who is to come’ (Matthew 11: 2–3)? Having observed how the Fathers strove to distance John from the perils of doubt in their readings of this passage, it traces the way their arguments were picked up by twelfth- and thirteenth-century biblical exegetes and then by authors of anti-heretical dispute texts in urban Italy, where the Baptist was a popular patron saint. So as to give force to their own counter-arguments, learned polemicists, clerical and lay, made much of heretics’ hostility to John, powerfully ventriloquizing a doubting, sceptical standpoint. One counter-argument was to assign any doubts to John's disciples, for whose benefit he therefore sent to ask for confirmation of the means of Christ's return, neatly moving doubt from questions of faith to epistemology. Such ideas may have seeped beyond the bounds of a university-trained elite, as is perhaps visible in a fourteenth-century fresco representing John in prison engaging with anxious disciples. But place, audience and genre determined where doubt was energetically debated and where it was more usually avoided, as in sermons for the laity on the feast of a popular saint.
