China is well known for providing official data, but how to treat these data is a longstanding debate among China scholars. This paper advances understandings of how to interpret Chinese official statistics about the internet. Using standards for evaluating surveys in the social sciences, we systematically compare official data from the China Network Information Center (CNNIC), which is under the supervision of China’s main regulator of internet policy, with the China Internet Survey 2018 (CIS), which is, to our knowledge, the first nationally representative survey on internet use in China. Using three examples, we illustrate how methodological differences in sampling design and measurement can lead to vastly different conclusions about key indicators of internet use in mainland China, including the percentage of internet users, their regional and urban–rural digital divide, and the percentage of specific social media platforms. We discuss the challenges of survey work on internet use in China and offer recommendations on how to interpret official statistics, especially in light of the limitations researchers face when conducting face-to-face surveys in China.

This article examines the evolution of the role played by the number and gender of siblings in the survival and biological well-being of individuals in rural Spain during the twentieth century. Our aim is to test how two fundamental theories – the cooperative breeding hypotheis and the resource dilution hypothesis – about how the number of siblings affect the individual come together in this area of study during a period of economic, health, and social transformation. We used a sample of 19,331 individuals born between 1900 and 1979 from 14 rural villages, for whom data on sibling count and various family and environmental variables are available. Using these data, we ran several statistical models to discover the effects of siblings on survival. In addition, we studied the long-term effect of siblings on height using height data from 2,783 male conscripts. Our results show that the number of siblings positively influenced survival, either through the cooperation of older siblings in the care of their younger brothers and sisters or through parents exhibiting higher offspring survival abilities. However, increased reproductive success may come with a disadvantage. The biological well-being, as measured by height, of male conscripts was significantly lower among individuals with more siblings in the early decades of the study. Conversely, in the later decades, the negative relationship between sibship size and height was not statistically significant when the number of living siblings was fewer than five.

This paper examines so-called active participles in three languages with different morphological systems (Bosnian/Croatian/Serbian, English and Hebrew). Based on a range of morphological, syntactic and interpretational diagnostics, I argue that these elements are uniformly deverbal adjectives. This result challenges a substantial body of work claiming that active participles show an adjectival/verbal ambiguity, but it is in line with Bešlin (2023), which analyzes passive participles as deverbal adjectives. Importantly, deverbal adjectives may denote predicates of properties or predicates of eventualities (events or states), depending on the characteristics of the verbal structure they embed. If these conclusions generalize to other languages, then there is no need to assume that (verbal) participles constitute a separate grammatical category, which is a desirable theoretical outcome. The results presented in this paper argue for an architecture of the grammar in which there is no one-to-one mapping between an item’s syntactic category and its meaning.

The interaction between international law and constitutional law has been increasingly recognized as salient to understanding the functioning of both and hence as worthy of academic attention. This Introduction to a special issue on how a selection of five Asian courts engage with international law when adjudicating constitutional cases explains the significance of studying such judicial behaviours, outlines the conceptual framework to be used in this regard, and identifies and reflects on some of the key findings from the case studies, including by highlighting domestic constitutional factors that help account for observed divergencies in judicial approach. This contribution also points to the value of examining courts’ attitudes towards international law for a variety of scholarly debates.

We describe Swauka ypresiana n. gen. n. sp., the second fossil gossamerwing damselfly (Odonata, Zygoptera, Epallagidae, Epallaginae) and its oldest occurrence. It is the first fossil insect reported from the Swauk Formation of central Washington State, U.S.A. It was recovered from the “Sandstone facies of Swauk Pass,” a fluvial unit, immediately below the Silver Pass Volcanic Member of the Swauk Formation, which has a U–Pb zircon CA-ID-TIMS age of 51.364 ± 0.029 Ma. The host deposits probably represent mud-dominated floodplain lake or oxbow lake environments.

Tricuspid atresia with absent pulmonary valve and intact ventricular septum is an exceedingly rare CHD. Only few cases with completed single ventricle palliation have been reported in the literature. We present the follow-up case of a 4-year-old child with this cardiac anomaly who underwent Fontan operation after complete exclusion of the right ventricle.

Mauro Cappelletti’s waves of domestic and transnational constitutionalism have reached Asia where courts exercise constitutional review and engage with international law in the process. Institutional and sociological legal scholars celebrate this as the inexorable global constitutionalization of international law through the liberal structures of judicial review and dialogue. A previous article cast doubt on the inevitability of global constitutionalization in view of material inconsistencies in interactions with international law by Asian courts, even those with rule of law and liberal democratic traditions. The present article on the Philippine Supreme Court sheds light on an underlying cause: arbitrary and contradictory selection and application of secondary rules for identifying international law by its source. The consequent degradation of international law and delegitimization of judicial engagement with it are the makings of the third wave of judicial review that Doreen Lustig and Joseph Weiler warned will reverse the gains of transnational constitutionalism.

The older population is increasing. As age increases, many changes occur in individuals’ lives, physically, socially, psychologically, and this situation varies from individual to individual. The uncertainty about how this period will pass can cause anxiety in individuals. Therefore, valid and reliable tools are needed to investigate ageing anxiety and potential factors that increase this anxiety, especially in the ageing population. This article presents the results of a Turkish validity and reliability study of the Aging Anxiety Scale for Middle-Aged Adults. The study sample consisted of 293 middle-aged adults. Content validity, face validity and construct validity methods were applied to measure validity. Item analysis, Cronbach’s alpha and test-retest methods were used to measure internal consistency in the reliability analysis. The content validity index of the Aging Anxiety Scale for Middle-Aged Adults was found to be 0.97 based on expert opinion. Model fit indices were calculated as χ2 = 473.583, df = 275, χ2/df = 1.722, CFI = 0.95, GFI = 0.89, IFI = 0.95, TLI = 0.94, RMSEA = 0.05, RMR = 0.06 and SRMR = 0.05. The analysis results indicated that the scale model values were within accepted limits and that the 5-sub-factor and 26-item structure of the scale was confirmed. It was concluded that the Turkish version of the Aging Anxiety Scale for Middle-Aged Adults was a valid and reliable measurement tool to enable Turkish society to determine middle-aged individuals’ ageing concerns.

Amdeberhan et al. [‘Arithmetic properties for generalized cubic partitions and overpartitions modulo a prime’, Aequationes Math. (2024), doi:10.1007/s00010-024-01116-7] defined the generalised cubic partition function $a_c(n)$ as the number of partitions of n whose even parts may appear in $c\geq 1$ different colours and proved that $a_3(7n+4)\equiv 0\pmod {7}$ and $a_5(11n+10)\equiv 0\pmod {11}$ for all $n\geq 0$ via modular forms. Recently, the author [‘A note on congruences for generalized cubic partitions modulo primes’, Integers 25 (2025), Article no. A20] gave elementary proofs of these congruences. We prove in this note two infinite families of congruences modulo $5$ for $a_c(n)$ given by

$$ \begin{align*} a_{25c+4}(25n+18)&\equiv 0\pmod{5},\\ a_{25c+9}(25n+8)&\equiv 0\pmod{5} \end{align*} $$

for all $c\geq 0$ and $n\geq 0$ using elementary q-series manipulations.
