In this study, we investigated the conceptual approaches to disability and ageing in two leading social scientific journals (Ageing & Society [AS] and Disability & Society [DS]) of the research fields that form the bases of policies on disability and ageing. This study aimed to identify the journals’ trajectories of conceptual development and their differences, and through that, find possible pathways for further interaction between the yet largely separate policy frameworks for disability and ageing. Our analysis showed considerable differences between the conceptual approaches of the two journals, with the dominant approach in DS being sociomaterial and individual-functional in AS. We conclude this paper by identifying the conceptual gaps in the respective journals, suggesting a further collaboration between the approaches in research as well as policies. These gaps could be potentially narrowed, leading to a constructive dialogue on older disabled people.

There is increasing recognition that Indigenous knowledges have considerable potential to enhance collective understandings of and improve responses to complex ecological threats, such as those to cultural heritage from climate change. At the same time, it appears that Indigenous peoples face structural barriers to participation in international organisations that advance knowledge about those problems. Using the conceptual framework of boundary organisations (BOs) theory and case studies of the Intergovernmental Panel on Climate Change (IPCC) and UNESCO, I argue that the lack of meaningful Indigenous engagement in international knowledge institutions is not just an ethical problem; it also undermines the effectiveness of their assessments. The future success of their boundary work partly depends on further engagement with Indigenous stakeholders. At least at the heritage–climate change nexus, the salience, legitimacy, and credibility of IPCC and UNESCO assessments require substantive Indigenous representation alongside other state/non-state parties. Successful experiences in biodiversity governance indicate that incorporating the principles of the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) would enhance Indigenous engagement in UNESCO and the IPCC.

Georgia lies to the northeast of Türkiye, having a western border on the Black Sea. With a population of some 3·73 million, Georgia has a tradition of gastronomic excellence dating back millennia. However, changing lifestyles and external influences have, as elsewhere, led to problems of suboptimal nutrition, and lifestyle-related diseases and disorders prevail. There is considerable scope for improving the focus on public health (PH) and nutrition in Georgia. With this in mind, the Georgian Nutrition Society teamed up with The Nutrition Society of the UK and Ireland and the Sabri Ülker Foundation, a PH charity based in Istanbul, Türkiye, to host a conference and workshops in Tbilisi, Georgia. The primary purpose was to review the current status of PH and nutrition in Georgia with reference to the situation elsewhere, to share examples of best practice and to identify opportunities for improvement. A particular highlight was the presentation of a programme of nutrition education for family physicians recently implemented in Türkiye. This summary of the proceedings is intended as a blueprint for action in Georgia and also to inspire others to consider how PH might be improved via a focus on balanced nutrition.

Behavioural treatments are recommended first-line for insomnia, but long-term benzodiazepine receptor agonist (BZRA) use remains common and engaging patients in a deprescribing consultation is challenging. Few deprescribing interventions directly target patients. Prescribers’ support of patient-targeted interventions may facilitate their uptake. Recently assessed in the Your Answers When Needing Sleep in New Brunswick (YAWNS NB) study, Sleepwell (mysleepwell.ca) was developed as a direct-to-patient behaviour change intervention promoting BZRA deprescribing and non-pharmacological insomnia management. BZRA prescribers of YAWNS NB participants were invited to complete an online survey assessing the acceptability of Sleepwell as a direct-to-patient intervention. The survey was developed using the seven construct components of the theoretical framework of acceptability (TFA) framework. Respondents (40/250, 17.2%) indicated high acceptability, with positive responses per TFA construct averaging 32.3/40 (80.7%). Perceived as an ethical, credible, and useful tool, Sleepwell also promoted prescriber–patient BZRA deprescribing engagements (11/19, 58%). Prescribers were accepting of Sleepwell and supported its application as a direct-to-patient intervention.

On January 17, 2023, the Grand Chamber of the Court of Justice of the European Union (CJEU) delivered its judgments in case C-632/20, P Spain v. Commission (Kosovo), ruling that notwithstanding the European Union's non-recognition of Kosovo as a state, Kosovo may participate in an EU agency, namely the Body of European Regulators for Electronic Communications (BEREC). The judgment is significant for several reasons: (1) for the European Union's growing engagement with non-recognized territorial entities since it clarifies the meaning of the concept of “third country” and confirms that such entities may participate in EU agencies; (2) for the European Union's engagement with Kosovo—particularly in the light of Kosovo's 2022 bid for EU membership; and (3) more broadly, in the context of the burgeoning debate regarding the CJEU's approach to international law.

Charmarite, Mn4Al2(OH)12CO3⋅3H2O, is a hydrotalcite supergroup member (or layered double hydroxide, LDH) with a previously unknown crystal structure and a Mn2+-analogue of quintinite (commonly erroneously reported as ‘2:1 hydrotalcite’). The single-crystal X-ray diffraction (XRD) data were obtained from the specimen from Mont Saint-Hilaire, Québec, Canada and are best processed in the space group P$\bar{3}$, a = 10.9630(4), c = 15.0732(5) Å and V = 1568.89(12) Å3. The crystal structure has been solved by direct methods and refined to R1 = 0.0750 for 3801 unique reflections with Fo > 2σ(Fo). The charmarite structure has long-range periodicity in the xy plane due to $2\sqrt 3$a’ × $2\sqrt 3$a’ scheme (or 11 × 11 Å) determined for LDHs for the first time (where a’ is a subcell parameter ≈ 3.2 Å). This periodicity is produced by the combination of two superstructures formed by: (1) Mn2+ and Al3+ ordering in the metal-hydroxide layers [Mn4Al2(OH)12]2+ according to the $\sqrt 3$a’ × $\sqrt 3$a’ pattern and (2) the (CO3)2– ordering according to the 2a’ × 2a’ pattern in the [CO3(H2O)3]2– interlayer sheet in order to avoid close contacts between adjacent carbonate groups. The $2\sqrt 3$a’ × $2\sqrt 3$a’ superstructure is an example of the adaptability of the components of the interlayer space to the charge distribution of the metal-hydroxyl layers. The Mn2+ and Al3+ cations have a large difference in size, which apparently leads to the considerable degree of their order as di- and trivalent cations resulting in a higher degree of statistical order of the interlayer components. Both powder and single-crystal XRD data show that the samples studied belong to the hexagonal branch of two-layer polytypes (2T or 2H) with d00n ≈ 7.57 Å. The chemical composition of the samples studied is close to the ideal formula. The Raman spectrum of charmarite is reported and the band assignment is provided.

The descriptions of two co-occurring cardioid crustaceans from the Ballagan Formation (Tournaisian, Lower Carboniferous) of Chirnside, Scottish Borders, help to resolve the taxonomy of the genus Tealliocaris. Tealliocaris robusta Peach, 1908 is assigned to Schramocaris to form S. robusta (Peach, 1908) comb. nov. on the basis of morphological characters such as the rugosity and position of the branchial carinae as well as the nature of the pleon, and becomes the earliest representative of this genus in Scotland. A new species of Tealliocaris is also recognised from this locality and is described as T. briggsi sp. nov., based on the smooth carapace, lack of pleonic grooves and the number of spines on the scaphocerite and lateral margin of the anterior carapace. The systematic position of the Pendleian specimens identified by Peach (1908) as ‘Tealliocaris robusta var.’ is finally resolved and described as T. weegie sp. nov.

In this note, we establish a boundary maximum principle for a class of stationary pairs of varifolds satisfying a fixed contact angle condition in any compact Riemannian manifold with smooth boundary.

This essay employs the anthropological notion of female social agency to analyse a selection of case studies in the art history of the late Byzantine Empire. They concern three women – Nicoletta Grioni, Isabelle de Lusignan, and Maria d'Enghien-Brienne – who lived between the mid- to late fourteenth century and the first half of the fifteenth. All three were part of a Greek-Latin Mediterranean socio-cultural context. While their stories are not fully represented in textual primary sources, the present essay examines a selection of heterogeneous visual and cultural materials that help to reinstate their role in history and overcome the male-logocentric nature of the written evidence related to them.

This article focuses on three Byzantine capitals acquired by Edwin Freshfield and later donated to the church of the Wisdom of God in Lower Kingswood, which provide us with two ways to see through Byzantium. The first looks at their original Constantinopolitan context lost at the time of their acquisition. The second reflects on how Byzantine materials attracted wealthy Western European collectors, who combined antiquarian curiosity with the quest for the authentic Christian faith. Their privileged status allowed them both to possess these witnesses of the sacred past and even to project their own image to posterity as being analogous to that of Byzantine patrons.

The new states that were established in the autumn of 1918 presented themselves as something new and better. Not only were they supposed to be the embodiment of the “national yearnings” of the formerly “oppressed nations” of the Habsburg Empire, but they were also meant to be more democratic and it was promised that their administrations would work better and their economies would flourish. In short, they were to be a decisive break with the imperial past. However, the new nation-states often could not deliver on these lofty promises, and, as a result, their legitimacy began to erode rather rapidly. In this context, the inability to quickly improve the food supply played an important role. In the Slovene part of Yugoslavia, the inadequate supply of basic foodstuffs, rationing, and increasing prices made the already volatile situation worse, as parts of the population began to grumble, protest, and yearn for the Habsburgs, looking across their northern and western borders. Police and court files, district captains’ reports, and various other sources indicate that after the proclamation of independence the mood of the population quickly soured, and that the legitimacy of the new state was often questioned.

Following a debate at the Parliamentary Assembly of the Council of Europe (PACE) on January 26, 2023 (7th sitting), under the urgent procedure, a text was adopted by 100 votes in favour, none against, and one abstention: a Resolution on the “Legal and human rights aspects of the Russian Federation's aggression against Ukraine.”

Tomila Lankina’s The Estate Origins of Democracy in Russia, published by Cambridge University Press in 2021, is a very powerful and thought-provoking book. It contains a bold argument, exhibiting the author’s erudition across several disciplines, as well as an unusual richness of empirical evidence and an exquisite prose style. The book delves into the intricacies of social resilience in the aftermath of the Russian Revolution. Contrary to the notion that the Bolshevik Revolution served as “the great leveler,” Lankina demonstrates the enduring presence of Tsarist-era estates within the social fabric throughout the Soviet era and even into the post-Soviet period. The estates encompassed a system of legal classifications that stratified Russian imperial society into distinct categories: aristocracy, clergy, merchants, and meshchane (petty bourgeoisie), as well as peasants. Lankina’s primary focus lies upon the meshchane, an estate that, by the twilight of the tsarist regime, accounted for approximately 10 percent of the empire’s total population.1 Within Lankina’s narrative, the meshchane emerged as an imperial middle class – comprising individuals such as small shopkeepers, rentiers, doctors, teachers, engineers – who mostly resided in urban centers and towns. Many among this group hailed from ethnic and religious minority backgrounds, including Jewish, Polish, German, Old Believers, and others.

Let G be a graph with m edges, minimum degree $\delta $ and containing no cycle of length 4. Answering a question of Bollobás and Scott, Fan et al. [‘Bisections of graphs without short cycles’, Combinatorics, Probability and Computing 27(1) (2018), 44–59] showed that if (i) G is $2$-connected, or (ii) $\delta \ge 3$, or (iii) $\delta \ge 2$ and the girth of G is at least 5, then G admits a bisection such that $\max \{e(V_1),e(V_2)\}\le (1/4+o(1))m$, where $e(V_i)$ denotes the number of edges of G with both ends in $V_i$. Let $s\ge 2$ be an integer. In this note, we prove that if $\delta \ge 2s-1$ and G contains no $K_{2,s}$ as a subgraph, then G admits a bisection such that $\max \{e(V_1),e(V_2)\}\le (1/4+o(1))m$.

The main theme of this paper is to study $\tau $-tilting subcategories in an abelian category $\mathscr {A}$ with enough projective objects. We introduce the notion of $\tau $-cotorsion torsion triples and investigate a bijection between the collection of $\tau $-cotorsion torsion triples in $\mathscr {A}$ and the collection of support $\tau $-tilting subcategories of $\mathscr {A}$, generalizing the bijection by Bauer, Botnan, Oppermann, and Steen between the collection of cotorsion torsion triples and the collection of tilting subcategories of $\mathscr {A}$. General definitions and results are exemplified using persistent modules. If $\mathscr {A}=\mathrm{Mod}\mbox {-}R$, where R is a unitary associative ring, we characterize all support $\tau $-tilting (resp. all support $\tau ^-$-tilting) subcategories of $\mathrm{Mod}\mbox {-}R$ in terms of finendo quasitilting (resp. quasicotilting) modules. As a result, it will be shown that every silting module (resp. every cosilting module) induces a support $\tau $-tilting (resp. support $\tau ^{-}$-tilting) subcategory of $\mathrm{Mod}\mbox {-}R$. We also study the theory in $\mathrm {Rep}(Q, \mathscr {A})$, where Q is a finite and acyclic quiver. In particular, we give an algorithm to construct support $\tau $-tilting subcategories in $\mathrm {Rep}(Q, \mathscr {A})$ from certain support $\tau $-tilting subcategories of $\mathscr {A}$.
