This article examines the role of normative power in shaping the global sustainability order. It challenges the prevailing focus on hegemonic leadership and norm diffusion from dominant states, arguing that less powerful states have contributed significantly to the global order by creating regional initiatives tailored to their unique contexts. The article adopts an alternative theoretical framework of norm-governed change, comprising norm-building, institutionalisation, and transformation. Using an illustrative case study of Africa’s regional economic institutions, it employs process-tracing and archival analysis of key policy documents. The study demonstrates how African states have proactively embedded environmental norms within their regional initiatives, while contributing to the global sustainability agenda, exemplifying a form of normative power referred to as ‘Green Pan-Africanism’. This approach broadens the understanding of global sustainability governance, positioning less economically powerful actors as active participants in world-making. The findings highlight the critical role of normative power in advancing global sustainability governance, particularly in addressing complex global challenges such as climate change.

We are living through cruel and frightening times. How should a progressive policy studies respond? Critique undoubtedly plays a role: the task of exposing the structural conditions, political interests and power asymmetries that lie beneath the ‘prosaic surface’ of policy is an urgent one. But are these primarily deconstructive efforts enough? Can they lead us out of this quagmire, alone? In this article, we argue that something additional – something more generative and hopeful – is also required. In response, we introduce ‘critical utopian policy analysis’ (CUPA) a methodological elaboration of critical policy analysis (CPA) designed to support its use in both deconstructive and reconstructive policy efforts. This approach builds on the theoretical offerings of critical policy analysis, utopianism and prefiguration, to posit a methodological embrace of critique, imagination, enactment and play. It seeks to mobilise a complex nexus of affect – including heartbreak and hope – to motivate and support a range of intellectual undertakings and emancipatory politics.

In this note, it is shown that the differential polynomial of the form $Q(f)^{(k)}-p$ has infinitely many zeros and particularly $Q(f)^{(k)}$ has infinitely many fixed points for any positive integer k, where f is a transcendental meromorphic function, p is a nonzero polynomial and Q is a polynomial with coefficients in the field of small functions of f. The results are traced back to Problems 1.19 and 1.20 in the book of research problems by Hayman and Lingham [Research Problems in Function Theory, Springer, 2019]. As a consequence, we give an affirmative answer to an extended problem on the zero distribution of $(f^n)'-p$, proposed by Chiang and considered by Bergweiler [Bull. Hong Kong Math. Soc. 1(1997), p. 97–101].

Elbow, with complex physiological structure, plays an important role in upper limb motion which can be assisted with exoskeleton in rehabilitation. However, the stiffness of elbow changes while training which decline the comfort and effect of rehabilitation. Moreover, the rotation axis of elbow is changing which will cause secondary injuries. In this paper, we design an elbow exoskeleton with a variable stiffness actuator and a deviation compensation unit to assist elbow rehabilitation. Firstly, we design a variable stiffness actuator by symmetric actuation principle to adapt the change of elbow stiffness. The parameters of the variable stiffness actuator are optimized by motion simulation. Next, we design a deviation compensation unit to follow the rotation axis deviation outside the horizontal plane. The compensation area is simulated to cover the deviation. Finally, simulation and experiments are carried out to show the performance of our elbow exoskeleton. The workspace can meet the need of daily elbow motion while the variable stiffness actuator can adjust the exoskeleton stiffness as expectation.

Recent research has shown that music interventions involving body movements are beneficial for reinforcing music learning. Given the reported positive transfer between music training and phonological skills, we investigated, for the first time, the value of an embodied music training program for improving pronunciation skills. In a classroom experiment, 48 Chinese adolescent learners of English participated in three 40-minute sessions of either Dalcroze-inspired embodied music training or treatment-as-usual non-embodied music training. Participants in the embodied music group were involved in a series of activities designed to develop their rhythmic and melodic skills through bodily experiences. Participants in the non-embodied music group followed music lessons designed by their music teacher, appreciating music pieces and receiving music knowledge. Before and after training, participants were tested with a language imitation task using six unfamiliar languages and an oral reading task in second language English. Results show that the embodied music group significantly outperformed the non-embodied music group in both tasks. Overall, our findings suggest that an embodied music training program has beneficial effects on pronunciation skills, supporting an embodied-based language teaching approach.

With the passage of the Climate Change Act, and to help meet its net zero obligations by 2060, Nigeria must transition from its dependence on fossil fuel energy sources to renewable energy. This will involve the procurement of large amounts of renewable energy by the government. In the past, procurement of power from the government-owned bulk trader has been chaotic, with no discernible strategy, and it is doubtful whether the government or Nigeria's citizens have derived value for money from the process. This article suggests a transition from the current, mostly unsolicited, proposal system to energy auctions, as the authors believe that this will help the country achieve low prices for renewable energy. The article also examines polices that have been implemented in other countries to drive energy auctions, with a view to applying relatable practices to the Nigerian exercise.

The article at hand introduces a comprehensive foundational database on the Czech Constitutional Court spanning from its inception in 1993 to 2023. The database includes metadata on all decisions, full-text corpus, and additional background data on judges and law clerks, filling a gap in high-quality datasets for empirical legal research in the Central and Eastern European regions. As one of the first comprehensive court databases in the CEE region, it has the potential to catalyze similar research efforts and contribute to methodologically rigorous empirical legal research in a region of increasing European significance.

This research explores the theory of authentic leadership and the critiques on the theory by analyzing the portrayals of Queen Elizabeth II, Princess Diana, and Margaret Thatcher in season 4 of the Netflix’s series The Crown. Utilizing directed qualitative content analysis, we seek to understand how authenticity in leadership is manifested, its limitations, and the role of gender within this framework. The investigation highlights the challenges leaders face between expected role fulfillment and genuine self-expression. It explores the benefits and drawbacks of authenticity, the attribution of authenticity when the leaders deviate from the formal roles, the nature of the role as influencing the expression of authenticity (e.g., degrees of freedom associated with each role) and the complex interaction between gender and authenticity. In response to these findings, the concept of ‘leader bounded authenticity’ is proposed, suggesting a balance between adhering to the formal role and the display of authentic leadership.

This article presents a new theory of majoritarian domination drawn from Bhimrao Ramji Ambedkar’s critique of majoritarian tyranny during the decades preceding British India’s decolonization. Ambedkar’s critique of British colonial pluralism and Congress-led Indian anticolonialism emphasizes attention to social structures and the mechanisms that produce and sustain communal majorities. He argues that caste prevents equality and fraternity, thus foreclosing the possibility of a democratic society. In such a context, Ambedkar argues that the majority is likely to be communal and fixed, rather than political, inclusive, and open to change over time. Ambedkarian majoritarian domination supplements nineteenth-century accounts of the institutional and epistemic dimensions of majoritarian tyranny. I defend comparison as a tool for theoretical analysis to show that Ambedkarian majoritarian domination can explain the interaction of hierarchical social structures with democratic politics in contexts beyond colonial India.

We study the problem of extending an order-preserving real-valued Lipschitz map defined on a subset of a partially ordered metric space without increasing its Lipschitz constant and preserving its monotonicity. We show that a certain type of relation between the metric and order of the space, which we call radiality, is necessary and sufficient for such an extension to exist. Radiality is automatically satisfied by the equality relation, so the classical McShane–Whitney extension theorem is a special case of our main characterization result. As applications, we obtain a similar generalization of McShane’s uniformly continuous extension theorem, along with some functional representation results for radial partial orders.

An (ongoing) interrogation of colonial wrongdoing is important for debates on decolonisation, restorative justice, racial and gender equality and global political and socio-economic equality. This article presents a theoretical study of colonialism’s legal-political injustices and aims to (re)turn the discussion on colonialism to the field’s most powerful insight, i.e. that of of epistemic violence and injustice. This article also suggests that the reach of this historical injustice went much further than the politics of autonomy, usurpation of territorial rights, political disenfranchisement and resource appropriation. To address the question of colonialism’s distinctiveness as a political mission, which has been discussed in recent debates within analytic philosophy, it argues that colonialism’s epistemic injustice, which denied the very existence and the traditions of the colonised, is the foundational and distinctive feature of colonialism as a political system and which drives its continued impact to this day.

The Vietnam Draft Lotteries, which randomly assigned men to military service, enable researchers to assess the long-term effects of interracial contact on racial attitudes. Using a new draft status indicator for respondents to the General Social Surveys 1978–2021, we show that white men who were selected for the draft subsequently expressed less negative attitudes toward Black people and toward policies designed to help them. These effects are apparent only for cohorts that were actually drafted into service, suggesting that interracial contact during military service led to attitude change. These findings have important implications for theories of political socialization and prejudice reduction.

Optimal vitamin D status is important for growth and development during childhood(1). Children with a circulating concentration of 25-hydroxyvitamin D [25(OH)D] below 25 nmol/L are at increased risk of rickets. In order to maintain 25(OH)D > 25nmol/L, a dietary intake of 10µg/d vitamin D is recommended for children aged 4 years and above(2,3). The aim of this study was to determine vitamin D status in healthy children and to investigate associations between 25(OH)D concentrations and muscle health, cognitive function, and parental knowledge of vitamin D, vitamin D habits, perceptions, and practices.

A cross-sectional study of healthy children aged 4 – 11 years conducted between 2019 – 2023 examined vitamin D status by measuring plasma 25(OH)D via the gold standard liquid chromatography tandem mass spectrometry and parathyroid hormone concentrations. Muscle strength (hand grip and balance) was determined by dynamometer, single and tandem stance balancing whilst cognitive function was assessed using the Cambridge Neuropsychological Test Automated Battery. Parents completed questionnaires to assess vitamin D knowledge, and perceptions, habits, and attitude towards vitamin D.

A total of 192 children (91 boys; 101 girls) with an average age of 8.2 years were recruited. Plasma 25(OH)D concentrations were 61.10±18.75 nmol/L (n = 190), with 68.4% of children defined as vitamin D sufficient (25(OH)D>50nmol/L). When stratified by winter months, only 58% of children were vitamin D sufficient. In single linear regression, plasma 25(OH)D concentrations were positively associated with dominant hand grip strength, single leg balance and the cognitive test ‘5choice movement time’ (p<0.05). Overall, there was a reported mean score of 41.9% for parental vitamin D knowledge and 68% of parents thought there was no harm in giving their child vitamin D fortified foods.

Approximately 70% of this sample of children were vitamin D sufficient, however insufficiency was prevalent in almost half of the cohort during the winter months. Benefits of optimal vitamin D for muscle and cognitive function were evident. These results support the promotion of the existing vitamin D dietary recommendations during the winter months for optimal child growth and development.
