The law concerning limitation periods has long been recognised to be unsatisfactory. One area which poses particular problems concerns whether a limitation period can apply to equitable claims “by analogy” under section 36 of the Limitation Act 1980. This article considers three relatively recent decisions of the Court of Appeal – P & O Nedlloyd BV v Arab Metals Co. (The UB Tiger) [2006] EWCA Civ 1717, [2007] 1 W.L.R. 2288, The Commissioners for Her Majesty’s Revenue and Customs v IGE USA Investments Ltd. [2021] EWCA Civ 534, [2021] Ch. 423 and The Claimants in the Royal Mail Group Litigation v Royal Mail Group Limited [2021] EWCA Civ 1173 – which illustrate that very different approaches have been taken. It is argued that The UB Tiger was wrongly decided, or at least should be limited to specific performance, and revives calls for legislative reform.

This paper examines the contest between Canadian American industrialist Cyrus Eaton and the Pugwash scientists’ leadership for influence over the early Pugwash scientists’ conferences. Eaton's activism has generally been dismissed in the historical literature as ineffective, naive and too uncritical of the Soviet Union. This paper argues that he was genuinely committed to international peace and security, that Eaton shared with Pugwash scientists a belief in the importance of intellectuals to global unity, and that he worked to bring about greater international peace and understanding through both his personal activism and his own conferences held in the town of Pugwash. Eaton, however, favoured a broader push for peace, which included participation by a wider range of intellectuals and a call for rapprochement with the Soviet Union. These differences between Eaton and the Pugwash scientists, I argue, were more than simply about approach: they represented different internationalist visions and manifested in different conceptualizations for the Pugwash scientists’ conferences. Eaton hoped to incorporate non-scientists and humanism into the conferences, and integrate them into his own broader conference programme at his Thinkers’ Lodge at Pugwash. The scientists, however, wanted to keep their conferences as distinctly scientists’ events, tied to science and its authority.

The heritage of World War II left an indelible mark on the relations between Italy and Yugoslavia. During the détente period, however, these two countries were able to overcome many historical resentments and established a fruitful co-operation in Cold War Europe. This article questions the engagement on state, regional and municipal levels and analyses the role of twin cities in this multilayered process. With the help of primary sources, we learn how the heritage of World War II played an important role in building new forms of post-war co-operation. In fact, post-war twinning is often the result of shared anti-fascist activities from the war years. However, this is not confined to communist municipalities or ‘red’ regions in Italy on one side, and socialist Yugoslavia on the other, but is a more fluid and flexible practice which involves historical ties, geographical positions, personal capacities and economic needs.

Astigmatism and myopia are two common ocular refractive errors that can impact daily life, including learning and productivity. Current knowledge suggests that the etiology of these conditions is the result of a complex interplay between genetic and environmental factors. Studies in populations of European ancestry have demonstrated a higher concordance of refractive errors in monozygotic (MZ) twins compared to dizygotic (DZ) twins. However, there is a lack of studies on genetically informative samples of multi-ethnic ancestry. This study aimed to estimate the genetic contribution to astigmatism and myopia in the Mexican population. A sample of 1399 families, including 243 twin pairs and 1156 single twins, completed a medical questionnaire about their own and their co-twin’s diagnosis of astigmatism and myopia. Concordance rates for astigmatism and myopia were estimated, and heritability and genetic correlations were determined using a bivariate ACE Cholesky decomposition method, decomposed into A (additive genetic), C (shared environmental) and E (unique environmental) components. The results showed a higher concordance rate for astigmatism and myopia for MZ twins (.74 and .74, respectively) than for DZ twins (.50 and .55). The AE model, instead of the ACE model, best fitted the data. Based on this, heritability estimates were .81 for astigmatism and .81 for myopia, with a cross-trait genetic correlation of rA = .80, nonshared environmental correlation rE = .89, and a phenotypic correlation of rP = .80. These results are consistent with previous findings in other populations, providing evidence for a similar genetic architecture of these conditions in the multi-ethnic Mexican population.

Intracrystalline distribution of ferrous and ferric iron within pumpellyites (VIIW8VIX4VIY8IVZ12O56–n(OH)n, Z = 1) from low-grade metamorphic green rocks of the Kanogawa unit in the Northern Chichibu Belt, Hijikawa district, western Shikoku, Japan, was investigated using electron microprobe analysis, X-ray Rietveld refinement, and 57Fe Mössbauer spectroscopic analysis to verify the regularity of the distribution of Fe within the octahedral X and Y sites in pumpellyite and its effect on the pumpellyite structure. Two Fe-rich pumpellyite samples, labelled CLW and CHG, with average total Fe2O3 of 10.01±1.69 and 16.07±1.08 wt.%, respectively, were separated from the rock samples. The site occupancies at the X and Y sites in the CLW and CHG pumpellyites, refined using powder X-ray diffraction data, are X[Mg0.298Fe0.298(5)Al0.405]Y[Fe0.191Al0.809] and X[Mg0.244Fe0.42(1)Al0.34]Y[Fe0.32Al0.68], respectively. The Fe2+:Fe3+ ratio of the CLW pumpellyite, determined using Mössbauer spectroscopy, is 12(1):88(3). By combining the average chemical composition data, the site occupancies at the X and Y sites, and the Fe2+:Fe3+ ratio of the CLW pumpellyite, the chemical formulae of CLW and CHG pumpellyites are constructed as (Ca7.96K0.02Na0.01)Σ7.99(Mg1.19Mn2+0.09Fe2+0.39Fe3+0.71Al1.62)Σ4.00(Al6.47Fe3+1.50V0.02Ti0.01)Σ8.00Si12.26O43.33(OH)12.67 and (Ca8.01K0.01)Σ8.02(Mg0.97Mn2+0.02Fe2+0.63Fe3+1.03Al1.19)Σ4.01(Al5.44Fe3+2.55V0.01)Σ8.00Si12.02O42.69OH)13.31, respectively, implying that the proper name of both pumpellyites is pumpellyite-(Al). The intracrystalline distribution coefficients of Fe3+ versus Al between the X and Y sites, KD = (Fe3+/Al)X/(Fe3+/Al)Y, are 1.62 and 1.90 for the CLW and CHG pumpellyites, respectively, implying stronger X-site preference of Fe3+ than Al3+. In the CHG pumpellyite, where the Fe contents at the X and Y sites are higher than in the CLW pumpellyite, the mean <X–O> and <Y–O> distances are 2.06 and 1.98 Å, respectively, which are larger than <X–O> = 2.040 and <Y–O> = 1.944 Å in the CLW pumpellyite. The unit-cell parameters of the CHG pumpellyite are a = 8.8672(3), b = 5.9562(2), c = 19.1899(6) Å, β = 97.473(2)° with V = 1004.9(2) Å3 and are larger than those of the CLW pumpellyite, a = 8.8456(4), b = 5.9393(2), c = 19.1613(8) Å, β = 97.461(3)° with V = 998.14(7) Å3.

In recent years, China has expanded its national weather modification programme to exploit climatic resources and adapt to climate change. The unprecedented scale of China's weather modification programmes has raised concerns over potential environmental impacts, including transboundary impacts. This article analyzes the domestic governance of weather modification in China and the extent to which this legal framework satisfies China's obligations under customary international law to minimize risks of significant transboundary harm. We find that existing arrangements do not satisfy procedural obligations under customary international law; nor do they adequately address the risks of environmental impacts associated with the increased use of weather modification. Procedures for transboundary environmental impact assessment (EIA) and engagement with regional neighbours are needed for China to comply with international law and promote stability in the region.

Modern Chinese diplomatic histories rarely discuss the marriages of diplomats, leaving the impression that women made little impact on their husbands' careers. The extraordinary performance of Oei Hui-lan (1889–1992), wife of celebrated diplomat Wellington Koo (1888–1985), challenges this view. Hui-lan's contributions to diplomacy call our attention to the role played by Chinese diplomatic wives: as reception hostesses and embassy managers, they cultivated social relationships to facilitate diplomatic exchange. Hui-lan's story reminds us that to study modern diplomatic history solely through the lens of professionalization and institutionalization – while forgoing perspectives of gender and family – is insufficient to explain China's success in this period. Hui-lan's Peranakan family background in the Dutch East Indies (now Indonesia) equipped her with the financial assets and cosmopolitan upbringing to shine as a diplomatic wife. And yet, though she benefited from her overseas origins, Hui-lan had an uneasy relationship to her Chinese identity. Concealing the tension in her two autobiographies, Hui-lan later reconstructed her past, emphasizing her patriotism and ethnic Chineseness to befit her established position. Thus, her case also shows how the complicated process of identity rebuilding and selective adaptation played out for elite overseas Chinese women through their engagement with modern China.

We present a learner corpus-based study of English article use (“a”/“the”/Ø) by L2 learners with four typologically distinct first languages (L1s): German and Brazilian Portuguese (both have articles), Chinese and Russian (no articles). We investigate several semantic and morphosyntactic factors—for example, specificity, prenominal modification that can affect article use. Our analysis of 660 written scripts from the Education First Cambridge Open Database confirms the lower overall accuracy of learners with no-article L1s. Our main finding is the differential effect of specificity on definite and indefinite articles: learners tend to associate specificity with “a,” which implies article omission with nonspecific indefinite singulars and overuse of “a” with specific indefinite mass nouns. Prenominal modifiers further contribute to perceived specificity, leading to article overuse with modified indefinite mass nouns. However, in definite contexts, prenominal modifiers are associated with increased article omission.

The focus of nutritionists is on improvement of the health impact of current diets. Therefore, it is important to ask the question whether healthy diets are more sustainable. This review provides an overview on the research on synergies between health and sustainability. Synergies are found from shifts from animal-based to plant-based diets, from ultra-processed foods to fresh and whole foods and from reduction of food waste. The importance of looking at sustainability of the present diets has led to steps made in Europe to incorporate sustainability into food-based dietary guidelines. Examples from UK, Nordics, Belgium and the Netherlands are given. World Wildlife Fund has summarised the insides in a future-proof diet: the planet-based diet within planetary boundaries.
