Measurements of the radiocarbon (14C) content of subannual wood cellulose samples over the 1963 bomb spike have revealed an apparent delay between the increase in atmospheric radiocarbon content and that of wood cellulose. This delay is apparent in both coniferous and deciduous tree species and is of a magnitude of approximately 4 weeks. The delay in wood cellulose 14C change as measured in a Sitka spruce from Washington state, USA, was previously used to estimate the relative influence of tree physiological effects contra environmental effects. We repeated the measurements with the increased measurement precision of today’s AMS systems and compare the new results to the ones of a Scots pine tree from Trondheim, central Norway and a white oak from Oregon state, USA. The results challenge the assumption that the 14C tree ring records directly show the atmospheric 14C concentration of a homogeneous, zonally well-mixed atmosphere. Instead, the apparent 1963 delay reflects local influences of the ecosystem and tree physiology. The 1963/1964 data allows for exploratory modeling of the effects of biospheric decay CO2 and local environmental influences assuming the absence of stored photosynthates from the previous year. Compared to the 10–30% contribution from biospheric CO2, the effects of delayed incorporation of carbon into the wood cellulose and the effect of stored photosynthate are small in the conifers. Highly detailed 14C records of stem cellulose can, in combination with stable isotope studies, contribute to our understanding of variability of the local carbon cycle, climate, and the environment.

The literature on vice presidencies fails to explain the women’s inclusion as vice-presidential candidates, as the strategies of ticket balancing predict a higher number of female running mates than what is observed. Based on theories of gender representation, this study develops hypotheses about the inclusion of women as vice-presidential candidates and tests them using an original dataset comprising 471 presidential tickets from Latin America (1978–2022), a region where women’s representation has expanded. The analysis reveals that small and left-wing parties nominate more women as vice presidents than major and right-wing parties. Although female vice-presidential candidates tend to have less political experience than their male presidential counterparts, they often add a diverse and complementary policy expertise to the ticket. The findings underscore that women’s inclusion as vice-presidential candidates depends mostly on partisan calculations, since gender quotas rarely apply to the vice presidency.

Commentary on the election of Pope Leo XIV has been framed in terms drawn from political and cultural oppositions: conservative vs liberal, traditionalist vs progressive, made vivid by the 2024 film Conclave based on Robert Harris’s 2016 novel. Part of my concern is to urge rejection of these as general terms of analysis of Catholicism, or at least to circumscribe their applications to matters inessential to Catholic faith and morals per se. In aid of that, and by way of broader purpose, I discuss the nature of Catholicism itself. Observing the long history of challenges, crises, and divisions, I then proceed to distinguish between subjective and objective modes of identifying the nature of individuals and institutions. Catholicism has a robust objective nature comprising a synthesis of Hebrew and Christian scripture, apostolic tradition, conciliar and other authoritative teachings, and sacramental practices, together consolidated and expressed in orthodoxy and orthopraxy. Political and cultural classifications are irrelevant to and distracting from this identification.

A meta-analysis was conducted to evaluate the effects of whey protein supplementation on growth performance, nutrient digestibility, blood parameters and carcase quality in broiler chickens. The dataset was compiled from studies published between 1964 and 2025, following the PICO framework, which included the following components: population = broiler chickens; intervention = various whey products (types of whey, inclusion methods and different inclusion levels); comparison = control versus treatment; and outcome = growth performance, nutrient digestibility, carcase traits, humoral immunity, antioxidant properties, intestinal morphology and microbiota composition. Overall, the inclusion of whey protein in broiler diets significantly improved average daily gain, feed intake, breast percentage and villus height (g’ > 0.500; P < 0.001). In conclusion, this meta-analysis highlights the strong potential of whey protein as an alternative protein source in poultry nutrition.

This paper investigates the permanent effect on total factor productivity (TFP) of temporary shocks. We estimate a structural vector autoregression to test the predictions of endogenous growth models over the business cycle. According to theory, the stock of technological knowledge promotes its flow as researchers “stand on the shoulders of giants.” Therefore, if R&D investment is pro-cyclical—as data show and theory predicts—a recession leads to a temporary deviation of the R&D level from its trend, thus reducing new knowledge creation. The lost technological advancements cause the economy to follow a parallel but permanently lower growth path. Our findings align with the primary theoretical prediction. Quantitatively, the US economy forgoes approximately 1.3% in TFP following an increase in cyclical unemployment that peaks at 1 percentage point above the mean. The historical variance decomposition shows a strong positive effect during the boom of the late 1960s and strong negative effects around the Volcker disinflation period and the Great Recession. Finally, we estimate the effects on R&D of a TFP shock to differentiate between different explanations on how the R&D pro-cyclicality arises. Our results align with models where financial frictions or nominal rigidities drive it.

Kongish Daily, a Facebook page promoting Kongish – a creative, critical, and colloquial form of Hong Kong English with Cantonese inflections – has attracted a following in social media over the past decade. It has also sparked interest among sociolinguists interested in (post-)multilingual developments in East Asia. This study is built on Hansen Edwards’s (2016) premise that Hong Kong English would gain wider acceptance in Hong Kong as the cultural identity of local language users shifted amidst sociocultural transformations. We first provide an overview of the Kongish phenomenon, followed by a qualitative study involving 30 active Kongish users from diverse age groups, genders and occupations. Through semi-structured interviews, we explore users’ perceptions of language and identity. Our findings support Hansen Edwards’s prediction regarding the strengthening of Hong Kongers’ cultural identification, while revealing an evolving, counter-stereotypical Hong Kong culture as well as an opinion divide on the future trajectory of Kongish.

Words in Tagalog/Filipino can be either penult-prominent or ultima-prominent. Scholars have been divided on whether the language has stress, or only phonemic vowel length in penults and default phrase-final prominence. Using a corpus of Original Pilipino Music, we find that both prominent penults and prominent ultimas are set to longer notes and stronger beats, even in phrase-medial position. We further find that among pre-tonic syllables, those that would plausibly attract secondary stress are mostly set to longer notes and stronger beats. Text-setting does not faithfully reflect differences in phonetic cues between the two types of prominence, nor is it sensitive to presumed phonetic differences between high and low vowels. We conclude that songwriters’ text-setting decisions reflect phonological stress in Filipino, and that both penult-prominent and ultima-prominent words bear stress.

Stroke is a prevalent neurological event that often induces significant motor impairments in the upper extremities, such as hemiplegia, which impacts bimanual coordination and fine motor skills. Robotic-assisted therapy has gained prominence as a contemporary rehabilitation modality, providing augmented motor repetitions and proprioceptive feedback, thereby potentiating neuroplasticity and functional recovery. This pilot study aimed to examine the therapeutic efficacy of a robotic intervention for wrist rehabilitation in two post-stroke adults aged 50–70 years. The intervention protocol, implemented biweekly over four weeks, encompassed 45-minute sessions consisting of passive muscle elongation (5 min) and robotic-facilitated exercises targeting pronation-supination (10 min), flexion-extension (10 min), and radial-ulnar deviation (10 min). Outcome measures included pre- and post-intervention assessments utilizing the motor activity log, Fugl-Meyer Scale, and robotic metrics for muscular strength. Results indicated enhancements in joint range of motion, motor precision, and neuromuscular control, with patient “B” demonstrating superior improvements, particularly in complex motor patterns. In contrast, patient “A” exhibited attenuated progress, attributable to pronounced baseline deficits and fatigue. Specific gains were observed in flexion-extension for patient “A” and pronation-supination for patient “B,” with minimal advancements in radial-ulnar deviation across both subjects. These findings provide preliminary evidence supporting the efficacy of robotic-assisted therapy in motor rehabilitation post-stroke with the novel proposed wrist rehabilitation device.

Grice’s foundational conversation model has inspired a range of influential developments, with various approaches to merging the maxims. This paper addresses unresolved controversies and circular dependencies that have fuelled assumptions of interdependence among the principles. It provides a revision of both Grice’s cooperative principle and the principles of truthfulness, relevance, informativeness and clarity, and extends them to include a principle of social conformity, which I collectively refer to as the TRICS-Principles. I demonstrate that the TRICS-Principles operate independently of each other at different levels and show the extent to which the other principles may function under the umbrella of a flouted principle of truthfulness. Furthermore, I distinguish the principle of social conformity from the concept of politeness, offering a nuanced perspective on their relationship. Finally, I provide new insights into factors influencing shifts in the prioritisation of the TRICS-Principles.

We extend the definition of the X-Rokhlin property to countable discrete groups and prove some permanence properties. If the action of a countable discrete group on X is free and minimal and the action of this group on the separable simple $C^*$-algebra has the X-Rokhlin property, then the reduced crossed product is simple.

In Where Do We Go from Here: Chaos or Community? the Reverend Dr. Martin Luther King, Jr. speaks with conviction on the need for and importance of community. King depicts American society and modern civilization as a great “world house” that is inhabited, inherited—and imperiled. Behind the metaphor of the world house is a prophetic vision and dream—the realization of what he called the “beloved community.” In this article, the author considers King’s beloved community ideal through a housing lens. Engaging with King’s metaphor, the author frames the beloved community as an apologetic for integrated community. The author views the metaphor of the world house as a significant means to expand understanding of beloved community, elevate housing as a moral-ethical concern, and engender radical structural solutions that can be realized through racial justice in the housing sector.

This article contributes to the ongoing debate on reactionary internationalism by linking it with scholarly discussions on civilisation and civilisationism, which have mostly been running in parallel trajectories. By doing so, it attempts to address the question of how the radical right, rooted in numerous particularisms, such as cultural, national, and religious, has managed to foster a global movement with an internationalist ideology that poses a significant challenge to the liberal international order. Through an analysis of the relevant literature and a case study of the Serbian radical right, this article tries to elucidate this question and bridge the gap between the two debates by demonstrating that civilisationism forms the core of reactionary internationalism, unifying the radical right from the West to the East. This article examines the Serbian case and its history of civilisational and geopolitical reactions as a possible paradigm for the contemporary radical right in general. Furthermore, it explores the role of Russian revisionism and war in Ukraine in shaping this civilisational discourse, specifically considering the narratives built around the Serbian foreign fighters’ network in Ukraine. An additional contribution of this article is that it provides a non-Western perspective on civilisation, religion, and nationalism.
