Captivity is a complex phenomenon in international politics with a broad range of purposes, functions, and consequences. Existing scholarship suggests that states use captivity, for example, to facilitate hostage or prisoner exchanges, to extract material rewards, or, in the case of human shields, for deterrence purposes. This article argues that states may use captivity to deter not only traditional military threats emanating from other states, but also perceived threats to regime security posed by non-state actors, including individuals, and that emotions are central to this process. The argument is illustrated through three empirical vignettes that show how the Chinese government has detained foreign academics, publishers, and NGO workers engaged in activities seen as threatening regime security. Detention is interpreted as attempts to deter such actors. While fear is often seen as key to successful deterrence, the article indicates that paying attention to other emotions can help better understand deterrence failure. Specifically, because captivity, and deterrence, involve the denial of the captive’s agency and may trigger feelings of humiliation and shame, it can backfire as the target of deterrence efforts might seek to act to regain agency.
The confession, as its name suggests, presents the personal, and often private, experience of the author, as we see in Rousseau’s well-known confessions which intend to expose his private self to public scrutiny. Bell’s confessional writing, however, is employed as a rhetorical means to serve his public purpose of political theorizing, since what the author intends to emphasize is not his private world, or even his personal experience as “a minor bureaucrat,” but to explore “the inner workings of Chinese academia and to draw implications for China’s broader political system” (3). Instead of a chronological reckoning of the history of the author’s life as an academic leader, Dean from Shandong has singled out several interconnected topics as a series of recollection of events Bell experienced in his five-year deanship to illustrate what he perceived as the important aspects of the Chinese culture in general and academic life in particular. The first-person narration, with its self-mocking style, foreshadows his intention behind the narrative, namely, his way of doing political theorizing as a political scientist. According to Northrop Frye, the confession is “introverted” and “thematic.”1 Bell’s confessions seem to be more thematic than introverted, “I invoke my personal experience only if it sheds light on social and political life in contemporary China, with its contradictions, diversity, and charm” (18).
Let X be a smooth proper rigid analytic space over a complete algebraically closed field extension K of $\mathbb {Q}_p$. We establish a Hodge–Tate decomposition for X with G-coefficients, where G is any commutative locally p-divisible rigid group. This generalizes the Hodge–Tate decomposition of Faltings and Scholze, which is the case $G=\mathbb {G}_a$. For this, we introduce geometric analogs of the Hodge–Tate spectral sequence with general locally p-divisible coefficients. We prove that these spectral sequences degenerate at $E_2$. Our results apply more generally to a class of smooth families of commutative adic groups over X and in the relative setting of smooth proper morphisms $X\rightarrow S$ of seminormal rigid spaces. We deduce applications to analytic Brauer groups and the geometric p-adic Simpson correspondence.
Constitutional democracies face significant threats. Such threats are countered by various theories of militant democracy and non-militant democratic self-defence, using a wide range of repressive, educational and social policy tools. The article introduces an alternative perspective on democratic self-defence policies, emphasising integration as a key component in maintaining the resilience of the constitutional community and draws on Rudolf Smend’s integration theory. It explores how constitutional design through its structures, powers, procedures, rituals and symbols shapes community cohesion and strengthens the constitutional order by deliberately using emotions.
This study aims to assess whether there was any excess mortality among the Aboriginal and non-Aboriginal populations in the Northern Territory (NT), Australia, during the COVID-19 pandemic. A time-series analysis using death data (1997–2023) was applied separately to the monthly and yearly death counts to develop an excess mortality surveillance model (using Auto-Regressive Integrated Moving Average (ARIMA)) for the NT population. Excess mortality was calculated by comparing expected deaths with actual deaths. In 2022, there was a statistically significant excess mortality of 193 (p < 0.01), compared with 82 recorded COVID-19 deaths. Excess mortality was significant for both the Aboriginal (N = 91) and non-Aboriginal (N = 102) populations in 2022. Even though some months had significant excess mortality among both Aboriginal and non-Aboriginal populations, the recorded COVID-19 deaths were not high in these months. This was associated with the peak of COVID-19 fatalities. The ARIMA model demonstrates deviations from expected deaths and helps understand the pandemic’s impact on the NT. Excess deaths occurred in 2022; however, no large spikes in most of the months suggest public health success in the NT.
Monocrotaline (MCT) induces lung injury and pulmonary hypertension (PH) by a mechanism that is in part due to oxidative stress. The purpose of this study was to determine how MCT affected nutrient antioxidants retinol and alpha-tocopherol in a rat lung and liver. Rats were fed a purified diet (AIN-93G) one-week prior to a subcutaneous injection of MCT (60 mg/kg) and remained on the diet throughout the study. Three weeks after injection, the animals were euthanized, and the lungs and livers were analyzed for retinol, alpha-tocopherol, phospholipid (PL), and cholesterol content. Lung retinol concentrations were significantly lower in MCT-treated rats, 2.0 ± 1.2 (nmol/g lung) vs. vehicle control (VEH), 5.8 ± 1.4 (P < 0.01). However, liver retinol concentrations were not significantly different, 3.3 ± 1.3 vs. 2.5 ± 0.9 nmol/g liver. Alpha-tocopherol was significantly greater in MCT-treated rats in the lung, 145 ± 24 vs. 99 ± 13 nmol/g lung (P < 0.001), and liver, 107 ± 30 vs. 47.7 ± 4.8 nmol/g liver (P < 0.001). Phospholipid and cholesterol were significantly lower in the lung of the MCT-treated group, but not significantly different in the liver. In conclusion, retinol along with phospholipid, and cholesterol were decreased in the lungs whereas alpha-tocopherol was elevated in the lungs and liver in response to MCT. These findings along with others suggest a novel mechanistic link between MCT-induced oxidative stress, lung vitamin A depletion, inflammation and the impairment of alveolar cell proliferation and repair. Pulmonary retinol is important in the pathogenesis of MCT-induced lung injury.
Rice (Oryza sativa L.) agriculture of the southern United States is plagued by strong biotic competition with several species in the Echinochloa genus. Despite clear genomic differences between barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] and junglerice [Echinochloa colona (L.) Link], the two major Echinochloa agricultural weeds are nearly indistinguishable phenotypically. This inability to reliably differentiate the species has led farmers to treat the group as a single species, often resulting in ineffective weed control efforts. In this study, we first develop a simple chloroplast-anchored PCR-based restriction enzyme assay to differentiate between E. colona and the other Echinochloa species of agricultural concern. Applying this assay, we identify a strong bias toward E. colona in 2024 rice field collections from eastern Arkansas. Finally, we evaluate anecdotal reports of interspecific hybridization between the species and find no evidence. Despite the drawbacks of the maternally inherited nature of the chloroplast genome, the availability of this species determinant assay will help USDA and academia extension agents and stakeholders to make educated, species-specific decisions about precision chemical weed control and field management.
We report a 24-year-old male with functional single ventricle who developed ventricular dysfunction associated with strangulation by a previous epicardial pacemaker lead. During conversion to dual-chamber pacing, the constricting ventricular lead was removed, with intraoperative echocardiography demonstrating improvement in apical contraction. Relief of mechanical compression, together with restoration of atrioventricular synchrony, likely contributed to the recovery of ventricular function.
Friends and popular peers are important sources of influence across the transition into adolescence. The present study examines the assertion that the magnitude of influence from friends and popularity-based norms varies across behavioral domains. Participants were 543 (268 girls, 275 boys) students from 29 5th–8th grade (ages 10 to 14) classrooms in three Lithuanian public middle schools. Most were ethnic Lithuanians. Self-reports of socioemotional adjustment, including emotional problems, lack of emotional clarity, problem behaviors, social media use, and weight concerns, were collected in the fall and winter of a single academic year, approximately three months apart. Popularity and academic achievement were assessed through peer nominations. Top-ranked best friends were identified from outgoing nominations. Status-based norms, calculated separately for each socioemotional adjustment variable in the fall (Time 1), represented popularity-weighted classroom averages. Results from longitudinal Group Actor-Partner Interdependence Model analyses indicated that best friends and status-based norms exerted differing amounts of influence over different behaviors. When both were included in the same model (with shared effects removed), best friends influenced emotional problems, lack of emotional clarity, and problem behaviors. Among older adolescents, best friends also influenced academic achievement. Status-based norms influenced social media use and, among older adolescents, weight concerns.
This study evaluated the growth trajectories of twins from birth to school age, focusing on weight and height z scores of children born in São Paulo. The longitudinal study comprised 188 healthy twins (M = 9.13 years; SD = 2.16). Weight data were obtained from birth records and reassessed at school age, and height at school age. Singleton birth weights and standard growth curves were used as reference points. Overall, the proportion of children with z scores below the median decreased significantly, from 98.3% at birth to 31.4% at school age. At birth, the dispersion of z-scores below the median was significantly greater among monochorionic compared to dichorionic twins (2.051 vs. 1.701), but this difference was no longer observed at school age (1.861 vs. 0.976). In total, 68.8% of the twins showed improved weight development, with no cases of deterioration. While monozygotic (MZ) and dizygotic (DZ) twin pairs exhibited comparable intertwin birth-weight differences, by school age MZ pairs exhibited more similar weights, whereas DZ pairs showed significantly greater weight discrepancies. For height at school age, mean height z scores were within the expected range for singletons. No significant differences were observed between monochorionic and dichorionic twins, whereas MZ pairs showed smaller within-pair height differences than DZ pairs. These findings suggest that although chorionicity plays an important role during the perinatal period — particularly due to the lower birth weights observed among monochorionic twins — its influence diminishes over time. By school age, weight and height differences are primarily determined by zygosity.
It is well established that attitudes towards immigration are linked to policy preferences and voting behaviour. However, we lack insights on the relevance of the other side of the migration coin: emigration. This is especially pertinent in the European Union (EU), which guarantees free movement of persons and where large-scale mobility gained momentum following the Eastern enlargement (East to West) and the euro crisis (South to North). Drawing on a 2021 survey conducted in nine peripheral EU countries, this study investigates whether concerns about emigration shape electoral behaviour. Findings indicate that such concerns reduce support for governing parties, but only among individuals with high levels of political trust, highlighting trust as a key moderating factor. At the country level, concerns about emigration favour radical-right parties, though not exclusively. In fact, the politicization of emigration can potentially benefit (or disadvantage) a range of parties depending on national political conditions.
Neurodevelopmental models regard impulsivity as a central risk factor for adolescent substance use. However, the practical utility of impulsivity in predicting substance use is complicated by variability among measures that encompass multiple methods and theoretical domains. Prior research has been constrained by cross-sectional designs, small sample sizes, and/or the use of a narrow subset of impulsivity measures.
Method
Leveraging the ABCD dataset (n = 11,868), we identified and replicated correlations among impulsivity measures and assessed their prospective longitudinal and concurrent predictive utility regarding adolescent substance use outcomes before 15 years old. We then used simulation to inform how associations between impulsivity and substance use vary across sampling strategies (population vs. high-risk cohorts) and sample sizes.
Findings
Correlations between questionnaire and behavioral measures of impulsivity were small, and questionnaires significantly outperformed behavioral measures in predicting substance use initiation, largely due to the contribution of the CBCL externalizing scale. Predictions of substance use based on impulsivity were statistically detectable but small according to clinical standards (AUCs 0.6–0.76), exhibiting sensitivity to sample size and base rate of substance use, and thus, poor absolute predictive performance. Large samples (n > 1,000) were needed to achieve adequate power for impulsivity measures to predict substance use initiation.
Conclusion
These results support a significant but small contribution of impulsivity in predicting the onset of early adolescent substance use, indicating that these factors alone are insufficient for clinically deployable prediction. In community samples, large sample sizes are needed for reproducible impulsivity prediction of adolescent substance use.
In his book The Work of the Holy Spirit, Kuyper begins (in the original Dutch version) with an extensive reference to John Owen. This raises the question of his relationship to Owen. Is his theology derived from John Owen? This study outlines Owen’s view of regeneration. We then consider how Kuyper developed his theology of regeneration. It appears that the metaphor of the ‘seed’ is central to his understanding of the new birth. The seed can retain its germinating capacity for years and only then sprout. When we compare this metaphor with Owen, it appears that Kuyper uses a concept that John Owen also uses, but he elaborates in a completely different way so that it ultimately becomes a different concept.
We report the experimental measurement of the density of states (DOS) associated with the soliton gas emerging during the development of the noise-induced modulation instability (MI) in optical fibres. By employing a time-lens-based heterodyne detection technique (SEAHORSE), we reconstruct the complex optical field and compute its nonlinear discrete spectrum within the framework of the inverse scattering transform. Our results show that, at early stages of the MI, the DOS matches the Weyl distribution predicted for an ‘ideal’ critically dense soliton gas, thereby confirming the relevance of the SG description for this nonlinear random wave regime. At larger effective propagation distances, we observe a progressive deformation of the DOS in the complex plane. We compare these observations with numerical simulations of a generalised nonlinear Schrödinger equation that includes losses, third-order dispersion and stimulated Raman scattering (SRS). Our simulations reproduce the main experimental trends and demonstrate that SRS is the dominant mechanism responsible for the spectral deformation. These findings highlight the need to extend the kinetic theory of soliton gas beyond purely integrable evolutions. In particular, our results call for a generalised kinetic equation (or generalised hydrodynamics description) that accounts for weak non-integrable perturbations such as SRS.
Volumetric changes in the superior temporal gyrus and anterior cingulate cortex have been repeatedly reported in studies on schizophrenia. Tractography and functional magnetic resonance imaging studies have suggested that alterations in connectivity involving the superior temporal gyrus and the anterior cingulate cortex are relevant to psychotic symptoms of schizophrenia.
Methods
We analyzed nanometer-scale three-dimensional structures of brain tissues of the superior temporal gyrus and the anterior cingulate cortex in eight schizophrenia and eight control cases and evaluated structural parameters of their neurons. We then examined the relation between the neuronal parameters and clinical information including auditory hallucination score.
Results
The obtained results indicated that 1) neurites become thin and tortuous in schizophrenia and that 2) somata become small in schizophrenia. The frequency distribution of neurite curvatures had a broad profile in the schizophrenia cases, whereas the control cases showed sharp peaks. In the scatter diagram of the standard deviation of neurite curvatures, the schizophrenia and control cases formed separate clusters, indicating that all 16 cases analyzed in this study can be assigned to either the schizophrenia or control group simply by using the diagram. The cingulate/temporal ratio of the standard deviation of neurite curvatures showed a strong positive correlation with the auditory hallucination score.
Conclusions
The structural alteration of neurites observed in the schizophrenia cases should influence the function of affected brain areas by hindering communication between distant neurons. We suggest that the interplay of the temporal and cingulate cortices in the whole-brain network is relevant to auditory hallucination.
Mugane (1997) identifies two types of individual-denoting nominalizations in Gĩkũyũ (Bantu): the [mu… a]-type and the [mu… i]-type. He argues that the [mu… i]-type nominalizations are phrasal and that the [mu… a]-type nominalizations exhibit a puzzling nature, displaying both lexical and syntactic properties. This study examines Mugane’s characterization, revisiting the notion of a lexicon-syntax divide. Applying Wood’s (2023) Complex Head analysis, I demonstrate that we can explain the [mu… a]-type nominalizations within a syntactic framework without resorting to the lexicon. The analysis reveals that the puzzle is resolvable and that syntax can account for both types of nominalizations in Gĩkũyũ.
