Studies investigating motivations for political participation in receiving-state politics among immigrant groups typically follow a traditional approach to understanding the process behind political engagement. In this work, the authors argue that this approach is insufficient if we want to understand the motivations of diasporic groups, notably in cases in which they are geographically close to home and influenced by both origin and receiving-state politics. This study examines the motivations for political party engagement among members of Bosnian diaspora in Austria and elucidates the links between political party membership and receiving-country political opportunity structures which formally result in political detachment from homeland politics. It does so through twenty-five interviews with Bosnian members of Austrian political parties conducted in fourteen cities in Austria. The article focuses on motivations for engagement in political parties which result in detachment from homeland politics and an identification with receiving-state politics. The findings reveal that pre-migratory experiences of war and membership in diasporic associations do not drive the motivations for engagement. Instead, their participation evolves from motives that are embedded in local experiences, while motives related to origin-state opportunity structures are negative or feebly present.

This article surveys the life and work of Benjamin Clough (1791–1853), Wesleyan Methodist missionary to Ceylon, focusing on his contributions to the study of Pali and Buddhism. It attempts to show that he inaugurated the Western study of Pali and that he should be recognised as one of the most important early scholars of Buddhism.

This article examines the evolution of breastfeeding practices in twentieth-century China, focusing on the complex interplay between medical knowledge, state policies and social transformation. This study demonstrates how medical recommendations concerning lactation timing, intervals and weaning were shaped by factors beyond purely scientific developments. Mid-twentieth-century biochemical studies validated traditional practices while revolutionising attitudes towards colostrum, marking a critical juncture in Chinese infant nutrition science. Following the establishment of the People’s Republic in 1949, maternal and child health initiatives underwent fundamental changes. Drawing on new understanding of breast milk’s nutritional value, health benefits, and economic advantages, healthcare professionals and state authorities actively promoted scientific breastfeeding methods. Their multifaceted approach reflected both the dissemination of medical knowledge and the state’s strategic consideration of female labour force participation. This study analyses how women’s liberation from feudal constraints, changing employment patterns, Soviet medical influence, and advances in artificial feeding technologies shaped breastfeeding practices. Through examining the intersection of medical advice, health policies, and women’s labour liberation, it provides fresh insights into the evolution of breastfeeding discourse within Chinese medical circles. Situating these developments within broader medical, social and cultural contexts, this research not only illuminates the multiple factors that shaped modern Chinese infant feeding practices but also contributes to our understanding of the complex relationships between medical practice, state policy, and social change in twentieth-century China.

Trans people are among the most marginalized and stigmatized groups globally, facing high risks of discrimination, violence and abuse. In Colombia, older adults experience significant vulnerabilities and poverty, which are exacerbated for those with diverse gender identities, a population that remains invisible in this country. The existing literature on the ageing experiences of trans individuals, particularly in Latin America, is scarce, yet trans individuals in this region face widespread violence and discrimination. This article addresses this knowledge gap by exploring the ageing challenges encountered by Colombian trans women, through a qualitative study involving 23 trans women aged 50–67 living in Bogotá. It finds that older trans women face barriers throughout their lives, including stigma, gender-based violence, stigmatizing policies and political erasure. While some barriers persist for their lifecourse, others emerge in later life. A few resources are available at the structural, societal and individual levels to help trans women in Columbia cope with the ageing process. This article contributes to the limited knowledge of ageing in trans populations in the Global South. It shows how legal and social frameworks are pivotal in shaping ageing experiences that are unique to Colombia in ways not thoroughly explored in the Global North. It underscores the need for inclusive policies and practices that address the specific challenges of trans older adults. By adding to the social gerontological scholarship, this article will help inform debates and guide future research and policy development.

For each closed subtorus T of $(\mathbb{R}/\mathbb{Z})^n$, let D(T) denote the (infimal) $L^\infty$-distance from T to the point $(1/2,\ldots, 1/2)$. The nth Lonely Runner spectrum $\mathcal{S}(n)$ is defined to be the set of all values achieved by D(T) as T ranges over the 1-dimensional subtori of $(\mathbb{R}/\mathbb{Z})^n$ that are not contained in the coordinate hyperplanes. The Lonely Runner Conjecture predicts that $\mathcal{S}(n) \subseteq [0,1/2-1/(n+1)]$. Rather than attack this conjecture directly, we study the qualitative structure of the sets $\mathcal{S}(n)$ via their accumulation points. This project brings into the picture the analogues of $\mathcal{S}(n)$ where 1-dimensional subtori are replaced by k-dimensional subtori or k-dimensional subgroups.

Green transition policies set long-term targets to reduce carbon emissions and other pollutants, posing a threat to workers in polluting occupations and communities reliant on them. Can far-right parties attract voters who anticipate losing from the green transition? We explore this in Germany, which has ambitious green policies and a large workforce in polluting occupations. The far-right AfD started campaigning as the only party opposing green transition policies in 2016. Using a difference-in-differences design, we show AfD support increased more in counties with larger shares of employment in polluting occupations once the AfD adopted an anti-green platform in 2016. A panel survey demonstrates that individuals in these occupations also shifted toward the AfD. Probing mechanisms, we find that far-right support may stem from shifting perceptions of social stigma and lower status. Our results highlight the need for a new research agenda on backlash against the normative dimension of the green transition.

The Douglas–Rachford algorithm is one of the most prominent splitting algorithms for solving convex optimization problems. Recently, the method has been successful in finding a generalized solution (provided that one exists) for optimization problems in the inconsistent case (i.e., when a solution does not exist). The convergence analysis of the inconsistent case hinges on the study of the range of the displacement operator associated with the Douglas–Rachford splitting operator and the corresponding minimal displacement vector. A comprehensive study of this range has been developed in finite-dimensional Hilbert spaces. In this paper, we provide a formula for the range of the Douglas–Rachford splitting operator in (possibly) infinite-dimensional Hilbert spaces under mild assumptions on the underlying operators. Our new results complement known results in finite-dimensional Hilbert spaces. Several examples illustrate and tighten our conclusions.

Animal welfare is a growing concern in dairy production, influencing consumer preferences and industry practices. While extensive research has been conducted in Europe and North America, limited data exist on consumers´ attitudes in Latin America, particularly Argentina. This study aimed to assess Argentine consumers’ perceptions, knowledge, and preferences regarding dairy cow welfare in grazing and confined systems. An online survey was conducted among Argentine residents (n = 3,051), assessing sociodemographic characteristics, knowledge of animal welfare, perceptions of dairy production systems, and willingness to pay for animal welfare-certified products. Most respondents (99%) believed that cows feel pain, and 85% believed they have emotions. Most respondents (91%) agreed that pasture access improves animal welfare. A significant portion (70%) expressed willingness to pay a premium for animal welfare-certified dairy products, with women (p < 0.001) and younger consumers (p < 0.001) showing higher interest. Women and respondents connected to the agricultural sector considered animal welfare more frequently when buying animal-based products compared with men and those without an agricultural connection (p < 0.001). Consumers without a direct agricultural background were more likely to perceive confined systems negatively. Grazing systems were widely preferred, with respondents associating them with better welfare, healthier products, and environmental sustainability. Our findings indicate a consumer preference for pasture-based dairy systems in Argentina. These insights can help industry stakeholders refine their communication strategies and promote welfare-oriented production practices that better align with consumer expectations

In the fields of meal-assisting robotics and human–robot interaction (HRI), real-time and accurate mouth pose estimation is critical for ensuring interaction safety and improving user experience. The complexity arises from the diverse opening degrees of mouths, variations in orientation, and external factors such as lighting conditions and occlusions, which pose significant challenges for real-time and accurate posture estimation of mouths. In response to the above-mentioned issues, this paper proposes a novel method for point cloud fitting and posture estimation of mouth opening degrees (FP-MODs). The proposed method leverages both RGB and depth images captured from a single viewpoint, integrating geometric modeling with advanced point cloud processing techniques to achieve robust and accurate mouth posture estimation. The innovation of this work lies in the hypothesis that different states of mouth openings can be effectively described by distinct geometric shapes: closed mouths are modeled by spatial quadratic surfaces, half-open mouths by spatial ellipses, and fully open mouths by spatial circles. Then, based on these hypotheses, we developed algorithms for fitting geometric models to point clouds obtained from mouth regions, respectively. Specifically, for the closed mouth state, we employ an algorithm based on least squares optimization to fit a spatial quadratic surface to the point cloud data. For the half-open or fully open mouth states, we combine inverse projection methods with least squares fitting to model the contour as a spatial ellipse and circle, respectively. Finally, to evaluate the effectiveness of the proposed FP-MODs method, extensive actual experiments were conducted under varying conditions, including different orientations and various types of mouths. The results demonstrate that the proposed FP-MODs method achieves high accuracy and robustness. This study can provide a theoretical foundation and technical support for improving HRI and food delivery safety in the field of robotics.
