An original analysis of Fabry–Perot cavity antennas based on thick partially reflecting sheet (PRS) is presented in this work. The bandwidth enhancement of such radiating devices with respect to Fabry–Perot cavity antennas based on thin PRS has been investigated through a leaky-wave, transverse-equivalent-network approach, and a field matching technique. This analysis led to an optimal condition for considerably improving the gain-bandwidth figure of merit for this class of radiating devices on a sound physical basis. A Fabry–Perot cavity antenna based on a thick PRS working at 60 GHz is discussed as a case study. An excellent impedance matching is finally achieved by means of an efficient feeding network designed through a fast ad hoc, hybrid, analytical-numerical method. Theoretical results are in an excellent agreement with full-wave simulations corroborating the proposed methods.

The article examines intellectual and political debates on human rights that took place between the European Economic Community (EEC) and the Africa, Caribbean and the Pacific Group of Countries (ACP) in the context of the Lomé Convention between 1988 and 1991. In this period, the debate between the two groups exploded and resulted in intellectual compromises, and had significant political consequences for the practical implementation of Lomé. Drawing on recently declassified archival material from the Historical Archives of the European Union, as well as periodicals and archival materials from the United Kingdom and France, the article traces the intellectual and political evolution of the issue of human rights in between the global north and global south. As a development cooperation agreement, Lomé provided a space for representatives of the EEC and the ACP to advance and negotiate their own understandings of human rights, particularly their supposed universality and their connection to development.

Let f(z) be the normalized primitive holomorphic Hecke eigenforms of even integral weight k for the full modular group $SL(2,\mathbb{Z})$ and denote $L(s,\mathrm{sym}^{2}f)$ be the symmetric square L-function attached to f(z). Suppose that $\lambda_{\mathrm{sym}^{2}f}(n)$ be the $\mathrm{Fourier}$ coefficient of $L(s,\mathrm{sym}^{2}f)$. In this paper, we investigate the sum $\sum\limits_{n\leqslant x}\lambda^{j}_{\mathrm{sym}^{2}f }(n) $ for $j\geqslant 3$ and obtain some new results which improve on previous error estimates. We also consider the sum $\sum\limits_{n\leqslant x}\lambda^{j}_{f }(n^{2})$ and get some similar results.

The current study represents the second phase of developing the Yangtze Finless Porpoise Welfare Assessment Protocol (YFP-WAP), guided by the Five Domains model (FDM). Based on previously validated indicators, it aimed to create a scoring system to quantify welfare states. Application of the FDM grading system to the YFP-WAF revealed that indicators with higher scores influenced overall outcomes disproportionately, highlighting limitations in the original approach. As a result, a new scoring system was developed to ensure a more balanced contribution from all indicators across domains. The scoring system allows the separate quantification of welfare enhancement and compromise to prevent compensation between positive and negative experiences. It employs the sum of numerical values for each indicator, along with a percentage-based normalisation system to account for variations in indicator numbers across domains, ensuring balanced contributions to final welfare scores. In addition, a preliminary ‘Critical Scoring’ tool was created, which prioritises key indicators to identify urgent welfare issues before full assessment. Through the implementation of a standardised, transparent, and adaptable scoring method, the YFP-WAP aims to support individual-level welfare monitoring to improve the living conditions of captive porpoises and facilitate interventions for ex situ breeding programmes of YFP, and other closely related species. Despite challenges associated with fully capturing the complexity of welfare dynamics, this framework offers a practical and scientifically grounded approach for the assessment of the welfare of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) under human care, that can also be applied or adapted to other cetacean species.

Since the 1990s, Chinese parents of people with intellectual and developmental disabilities (PWIDD) have been founding rehabilitation service non-governmental organizations (NGOs) to fill the social welfare gaps in disability services in their local areas. More recently, however, a new form of mutual aid organization – the parent organization, which focuses on family empowerment and advocacy – has emerged and diffused trans-locally, along with two national networks’ organizational incubation initiatives. Following an institutional approach to organizational studies and drawing on ethnographic fieldwork conducted between 2019 to 2023, this study traces the trans-local expansion of this novel organizational form in the emerging field of Chinese NGOs. We argue that parent organizations strategically orchestrate a form of institutional work – network entrepreneurship – characterized by three organizational processes: vertical connections between national networks and local member organizations, horizontal interactions among senior and new parent organizers, and the creative translation and adaptation of local parent organizations. Together, these three processes facilitate the trans-local diffusion of organizational resources, identity, ideas and practices. The findings make theoretical contributions by highlighting the institutional implications of peer organization networks, especially through the emerging subject position of “parent of PWIDD,” in the incubation and diffusion of a novel organizational form trans-locally.

Islands have a disproportionate role – as strategic locations, as imaginative or symbolic locales, as extractive zones and as ecological bellwethers – in oceanic imperial histories. They were and are places of ‘great practical use and metaphorical power’. And yet Newfoundland was seen (and continues to be seen) as marginal and peripheral, even if the biomass that was pulled out of its ocean fed – quite literally – a global network of exploitation. This article uses four overlapping maps to tell four overlapping stories: James Cook’s circumnavigation of the island in 1763–8; Lt David Buchan’s trek into the interior to contact the Beothuk in 1811 and 1820; William Eppes Cormack and Joseph Sylvester’s trek across the island in 1822; and finally, a series of story-maps created by Shanawdithit, who is apocryphally known as ‘the last of the Beothuk’. In doing so, it draws in Indigenous ‘storywork’ and cartographic histories and makes a case for storytelling as powerful methodology for examining overlooked colonial histories. These maps and stories highlight the complexity of encounter with a place rather than a coherence of colonial ideologies. Through the stories these maps help me tell, I hope to show how the peripheries of some people’s empires were the centres of other people’s worlds.
