We study the local limit in distribution of Bienaymé–Galton–Watson trees conditioned on having large sub-populations. Assuming a generic and aperiodic condition on the offspring distribution, we prove the existence of a limit given by a Kesten’s tree associated with a certain critical offspring distribution.

Despite a long tradition of research on dominant party systems (DPS), comparative analysis remains limited by conceptual ambiguities, regional and historical biases, and the absence of accessible data. This research note introduces the Global Dominant Party Systems (GDPS) Dataset, which includes 187 cases of executive dominance across 106 independent countries from 1900 to 2024, addressing the regional and historical biases that have traditionally plagued the literature. Drawing on foundational theories and refined concepts, the dataset differentiates between dominant parties and DPS and develops the minimal definition of DPS that focuses on executive arena and at least minimally contested elections. The dataset identifies cases with mechanical properties typical of DPS, that is those in which one party (or coalition) consistently monopolizes executive power and electoral competition fails to produce changes in government leadership. Despite setting permissive minimal criteria, the dataset also offers a broad range of variables on democracy, corruption and institutional features which can be used to set different criteria for case selection and conduct robustness checks. The dataset also includes variables on ethnic and opposition fragmentation, voter turnout, economy and population size, enabling researchers to investigate the institutional and socio-economic foundations of dominance across regime types and world regions. Finally, the proposed model of DPS evolution and change can serve as a useful guide for qualitative research on unpacking causal mechanisms. While limited to positive cases of dominance, the dataset offers new potential for cross-regional hypothesis testing and theory development on executive power, party system change, and democratic resilience.

In an observational study, healthcare personnel often entered contact precautions rooms without contacting patients or the environment. An approach requiring gloves and gowns based on actual contacts rather than for all room entries would reduce personal protective equipment donning and doffing time, cost, and carbon footprint by more than half.

Consider a subcritical branching Markov chain. Let $Z_n$ denote the counting measure of particles of generation n. Under some conditions, we give a probabilistic proof for the existence of the Yaglom limit of $(Z_n)_{n\in\mathbb{N}}$ by the moment method, based on the spinal decomposition and the many-to-few formula. As a result, we give explicit integral representations of all quasi-stationary distributions of $(Z_n)_{n\in\mathbb{N}}$, whose proofs are direct and probabilistic, and do not rely on Martin boundary theory.

This paper presents a new problem for the inference rule commonly known as Inference to the Best Explanation (IBE). The problem is that uncertainty about parts of one’s evidence may undermine the inferrability of a hypothesis that would provide the best explanation of that evidence, especially in cases where there is an alternative hypothesis that would provide a better explanation of only the more certain pieces of evidence. A potential solution to the problem is sketched, in which IBE is generalized to handle uncertain evidence by invoking a notion of evidential robustness.

In recent scholarship on the Ottoman Mediterranean, it has become commonplace to challenge narratives of heroic discovery and cultural superiority expounded in publications by European travellers. Rather than taking a polished, published account as its starting point, this paper discusses the travels of Edward Falkener (1814–96), a lesser-known Victorian architect and writer whose extensive tour around Anatolia (1844–5) was never communicated to a broader audience. If Falkener is remembered today, it is usually as the author of the first anglophone monograph on ancient Ephesus and editor of the first British academic journal devoted to classical art and architecture. This paper reviews Falkener’s career, but instead of these publications, the focus is on his remarkable personal archive of diaries, sketchbooks, watercolours, contracts and notes for an incomplete book about his tour of Anatolia. Drawing on this collection, it explores his fluctuating interests in heritage from different periods of Anatolia’s history and well-documented interactions with a variety of local actors who helped or hindered his meandering tour. Representing the first attempt to study Falkener’s journey, this paper explores the utility of his archive for understanding the challenges and contingencies of Victorian travel in the Ottoman Empire.

Public service internships are a staple in contemporary political science curricula. Research shows that internships produce better thinkers, employees, and citizens. Yet, political science interns are on the frontlines in observing the firsthand trauma, stress, and mental health challenges of many people seeking support and services from government. In turn, students may internalize this stress and trauma, a phenomenon recognized as secondary traumatic stress (STS). This study addresses a significant gap in the discipline’s understanding of the frequency and severity of STS experienced by political science interns in their fieldwork. We relied on surveys and written assessments from students enrolled in internship courses at two public universities. We find that interns report increased exposure to STS at the end of the semester. Furthermore, STS vulnerability varies among interns, with higher incidence rates among those with a history of primary trauma, older students, and women. We outline coping strategies for students, propose adaptations to experiential learning to enhance support, and emphasize the need for further research on this issue.

Today’s field of spatialisation in acousmatic music is very heterogeneous. Composers tend to develop their own technologies and techniques for spatialisation, and often the differences in how multichannel systems are addressed may influence both the musical appreciation and the future reproducibility of a piece. Moreover, the analytical and musicological perspectives of spatialisation are both fragmented and underdeveloped, with a lack of a shared framework for their study. This article focuses on these problems and tries to give a coherent and consistent view of spatialisation practice, from both technological and musicological perspectives. It will also act as a bedrock for the development of the musicological side of spatialisation, an aspect too often overlooked. ‘Spatial reduced listening’ and ‘spatial relativism’ will be introduced as analytical perspectives to shine a light on the composed spatial traits of sound, and not only on its spectromorphological and technological features.

Trust judgments involve rapidly evaluating others’ appearance and are critical in psychosocial development. Trust biases may be linked to psychopathology risk, particularly in vulnerable, adversity-affected populations, but very little is known about trust perception in refugee context. Here, we measured trust perception of Syrian refugee children (N = 324, Mage = 6.32 years) displaced in Jordan, using a validated trust task with computer-generated faces varying in perceived trustworthiness (data collection: May-August 2021). Mothers (N = 324, Mage = 32.59) reported on child and mothers’ mental health, and mother-child relationship. Child trust perception was not associated with child or mothers’ mental health, or mother-child relationship (all p > .10), but we found age-related changes in perceived trust, with older children reporting faces as less trustworthy than younger children (B = .32, p < .001). Although children’s social judgments might be associated with socio-emotional functioning in non-refugee populations, our results suggest that refugee children’s mental health does not seem to be linked to their perception of trust, and that trusting others might diminish with age in displaced, at-risk children.
