Many developed economies face declining fertility rates and aging populations, driven significantly by the rising prevalence of childless households. This paper extends a simple overlapping generations (OLG) model to examine how this trend affects household utility. By assuming heterogeneous preferences for child-rearing, the model treats the proportion of childless households as endogenous, determined by utility maximization. The analysis reveals that an increase in childlessness generally exerts a negative impact on overall household utility. Furthermore, the study evaluates childcare support policies, balancing the distortionary effects of higher taxes against the benefits of reduced rearing costs and enhanced social security from a larger future workforce. Numerical simulations suggest that while most households favor the introduction of childcare support, their preferred tax rates vary significantly. These findings highlight the complex trade-offs in policy design when addressing demographic shifts through fiscal interventions.

Construction safety inspections typically involve a human inspector identifying safety concerns on-site. With the rise of powerful vision language models (VLMs), researchers are exploring their use for tasks such as detecting safety rule violations from on-site images. However, there is a lack of open datasets to comprehensively evaluate and further fine-tune VLMs in construction safety inspection. Current applications of VLMs use small, supervised datasets, limiting their applicability in tasks they are not directly trained for. In this article, we propose the ConstructionSite 10 k, featuring 10,000 construction site images with annotations for three inter-connected tasks, including image captioning, safety rule violation visual question answering (VQA), and construction element visual grounding. Our subsequent evaluation of current state-of-the-art large pre-trained VLMs shows notable generalization abilities in zero-shot and few-shot settings, while additional training is needed to make them applicable to actual construction sites. This dataset allows researchers to train and evaluate their own VLMs with new architectures and techniques, providing a valuable benchmark for construction safety inspection.

Quebec sociopolitical context is currently characterized by two distinct political undertakings: on the one hand, a modernization of the Charter of the French Language, and on the other, a desire to establish a nation-to-nation relationship with the Indigenous peoples whose territory lies within Quebec. Although compatible in theory, these two projects are in tension in practice. This article thus proposes a critical analysis of the notion of a “common language” (“langue commune”) at the heart of Quebec’s language policies. This article argues that it relies on a conception of linguistic justice ill-suited for plurinational societies such as Quebec.

Despite growing interest in prediction during simultaneous interpreting (SI), the real-time processing mechanisms supporting it remain underexplored. This study employed the visual world paradigm to investigate whether interpreters can predict upcoming content while simultaneously interpreting multi-sentence paragraphs and to examine the mechanisms underlying prediction. Interpreting students and professionals simultaneously interpreted four paragraphs embedded with sentences containing a critical verb that manipulates the predictability of the target noun, while viewing visual displays containing a target object, two semantic competitor objects and one distractor object. Both groups made predictive eye movements to the target objects before hearing the corresponding word, indicating interpreters’ ability to predict in a challenging task. The observed fixation patterns further suggest the involvement of both prediction-by-production and prediction-by-association during SI. Crucially, professionals showed more flexible attention shifts and efficient cue use, whereas students shifted attention less and used a more cautious prediction strategy.

Maternal tobacco smoking during pregnancy (MSDP) is associated with an increased risk of child externalizing problems. It remains unclear whether these associations are externalizing-specific, or better explained by comorbidity between externalizing and internalizing domains, or vary by age and sex. To address comorbidity and differentiation between domains, we leveraged the severity-directional model of psychopathology. Severity reflects the overall level of psychopathology symptoms across both domains (high levels of severity can only be reached by having symptoms of both types simultaneously), whereas directionality captures the balance/differentiation of internalizing vs. externalizing symptoms regardless of number of total symptoms. Participants included 16,335 children aged 1–19 years old (47.78% female, 58.17% White, 75.46% non-Hispanic) from 55 U.S.-based cohorts within the Environmental Influences on Child Health Outcomes (ECHO) consortium. MSDP predicted differentiation toward externalizing problems in 2-year age bins 1–2 through 7–8 and 13–14 years; remaining (non-significant) age bins had similar magnitudes. MSDP predicted higher symptom severity in all age bins. Findings likely reflect a combination of MSDP associations with comorbid symptom severity and specificity toward externalizing problems, with little evidence of age or sex differences. Additional analyses explored e-cigarette use, other prenatal substance use, and postnatal smoke exposure; associations were sparse and unsystematic.

Le contexte sociopolitique québécois est marqué par deux entreprises politiques distinctes : d’une part, une modernisation de la Charte de la langue française, et d’autre part, une volonté d’établir un rapport de nation à nation avec les peuples autochtones dont le territoire se situe au Québec. Bien que compatibles en théorie, ces deux projets se retrouvent en tension dans la pratique. Cet article propose en ce sens une analyse critique de la notion de « langue commune » au coeur des politiques linguistiques québécoises. L’hypothèse générale est que cette idée repose sur une conception de la justice linguistique inadaptée à une société plurinationale comme le Québec.

It was a puzzle to the British and has been a puzzle to historians ever since, why the American colonists, who enjoyed a degree of liberty, political autonomy, and even low taxation that was the envy of subjects in the home country, would join in a risky revolution to sever ties with the nation of their origin. The answer, according to Edmund Burke, was in large part religion. “Religion,” he explained to fellow members of Parliament in his “Speech on Conciliation with the Colonies,” always a “principle of energy,” was “no way worn out or impaired” in North America—and that religion was of a particular kind. Burke wrote: “The religion most prevalent in our Northern Colonies is a refinement on the principle of resistance; it is the dissidence of dissent, and the Protestantism of the Protestant religion.” Of all faiths, this hyper-Protestantism, wrote Burke, is “the most adverse to all implicit submission of mind and opinion.” This article sets out the ecclesiological, experiential, and theological differences among the largest Protestant denominations in Revolutionary America and the ways in which these differences contributed not just to the revolutionary spirit, but to the democratic and republican strands of revolutionary and constitutional thought in the new United States. The biggest contrast was between members and clergy of the Church of England, who were most involved to remain Loyalists, Reformed Protestants (Congregationalists and Presbyterians), who inclined toward republicanism, and Baptists, who were the most democratic and individualistic.

Transvenous and epicardial pacing in children carries significant risks of lead failure and infection. Leadless pacing is an alternative with lower risks of infection, lead failure, and longer battery longevity. A retrievable leadless pacemaker was implanted in an 8-year-old, 24 kg patient with heart block. A systematic review evaluated procedural success and the safety of leadless pacemakers in preadolescents weighing less than 30 kg.

This study investigates how personality traits modulate the foreign language effect (FLe) in moral decision-making. Meta-analyses have shown that the FLe has a small-to-moderate effect size, suggesting that individual characteristics may constrain its impact. We hypothesized that traits promoting strong deontological tendencies would moderate this effect. Our results showed that lower conscientiousness and higher emotional stability were associated with more resilient deontological responses, showing reduced susceptibility to the FLe. However, deontological choices associated with lower extraversion were overridden in a foreign language. These findings offer the first empirical evidence that broad personality traits can modulate the FLe. Moreover, our results – statistically significant but modest in magnitude – highlight key methodological considerations, including dilemma types, trait measures, and sample characteristics. Finally, they also underscore the importance of examining more fine-grained personality constructs to better understand individual variability in the extent to which foreign language use shapes moral judgment.

The Ngezi–Vumawimbi Forest Reserve is the largest remaining patch of natural vegetation on Pemba Island, Zanzibar, Tanzania. In 2024, in collaboration with the Department of Forestry, Ministry of Agriculture, Zanzibar, we conducted a baseline biodiversity survey of animal and plant communities. Preliminary results reveal previously unrecognized plant diversity, including species likely new to science that are currently under study. We confirmed the presence of endemic and threatened plant species, and recorded populations of species not previously reported on Pemba Island. We also confirmed the presence of a small population of blue duiker Philantomba monticola, currently under threat from poaching. One of the areas richest in plant diversity is designated for development of a new tourist resort. This would replace most of the Vumawimbi evergreen coastal forest, home to a unique forest type in continental Africa dominated by Intsia bijuga.

Despite the social, political and personal importance of contentious death investigation, medico-legal autopsies have received scant socio-legal attention. By extending understanding of the importance of care for the dead in this context, this article begins to bridge that gap. To do this, I explore original empirical data from interviews with Anatomical Pathology Technologists who both assist during post-mortems and take responsibility for the care of the deceased’s body before and after autopsy. I argue that care is woven throughout their practice and identities. This care is enacted within a complex context of relations and regulations, such that practice can simultaneously be technically and morally ‘good’ (including actions that go beyond what is necessary or mandated). In making this argument, I both extend understandings of care to relationships with the dead, and contribute new insights into the way that coronial justice can, and should, gain legitimacy.

This article argues that music can reflect and express the ideas that define particular cultures by considering the presence of concepts from Canadian philosophy in the nation’s music. It begins by examining how musical compositions can incorporate philosophical notions before surveying some themes in Canadian philosophy. The article then identifies these concepts from Canadian philosophy in the musical compositions of artists such as Léo Pol Morin, R. Murray Schafer, Udo Kasemets, Michael Snow, Glenn Gould, R. Bruce Elder (this article’s author), and David Jaeger.

Jervell and Lange-Nielsen syndrome is a rare inherited disorder characterised by sensorineural hearing loss and a prolonged corrected QT interval, predisposing to malignant arrhythmias. We describe two adult sisters diagnosed after recurrent syncope. Genetic testing confirmed a homozygous KCNQ1 mutation. Awareness of this condition, even in adulthood, is essential to ensure diagnosis, appropriate treatment, and prevention of sudden cardiac death.

This article examines the default stress pattern of Sentani (Papuan), situates it within the typology of iambic stress patterns, and provides an analysis within the Weak Bracketing framework for metrical stress theory. Sentani is unique in sometimes employing clash (adjacent stressed syllables) and other times employing lapse (adjacent stressless syllables) in an effort to avoid final stress in even-parity forms. Clash is employed in four-syllable forms, but lapse is employed in longer even-parity forms. Key to the analysis are constraints insisting that both the initial foot and the final foot carry a stress. When the initial and final foot are adjacent (i.e., in four-syllable forms), insisting that both be stressed results in a clash. When the initial and final foot are not adjacent (i.e., in longer even-parity forms), a medial foot emerges without stress in order to avoid clash.

This article proposes queernotation as a lens to understanding existing works and as a way forward for composers and musicians who find themselves limited by traditional forms of music notation. Applying queer ways of knowing and creating, I investigate the inherent boundaries in notation and how queer theory can guide us to break out of them. Queernotation connects score types to three key areas of queer theory: queer erotics, queer temporalities and queer futurity. Extending these theoretical approaches to their musical possibilities, I identify three modes of queering notation. These approaches are demonstrated in this article through existing historical and recent works and practically applied in a chamber opera that tests concepts of queernotation in directing improvisers to perform conceptual ideas on the stage. Notation for electronic instruments and with digital mediums demonstrates how technology facilitates new approaches that can queer music notation.
