    (Cambridge University Press, 2025-09-25) Hasking P; Kiekens G; Petukhova MV; Albor Y; Al-Hadi A; Alonso J; Al-Saud N; Altwaijri Y; Andersson C; Atwoli L; Muaka CA; Báez-Mansur P; Ballester L; Bantjes J; Baumeister H; Bendtsen M; Benjet C; Berman A; Bruffaerts R; Carrasco P; Chan S; Cohut I; Couder MCD; Cristóbal-Narvaez P; Cuijpers P; David O; Dong D; Ebert D; Gaete J; Forero CG; Gutiérrez-García R; Haro J; Hunt X; Hurks P; Husky M; Jaguga F; Jansen L; Jiménez-Pérez A; Kählke F; Klinkenberg E; Langer Á; Lee S; Lima RA; Liu Y; Lochner C; Mac-Ginty S; Martínez V; Mason A; McLafferty M; Mori T; Murray E; Musyoka C; Nedelcea C; Núñez D; O’Neill S; Piqueras J; Popescu C; Rapsey C; Robinson K; Roca M; Rodriguez-Jimenez T; Salemink E; Sampson N; Scarf D; Siu O-L; Stein D; Struijs SY; Tomoiaga C; Valdés-García K; van der Heijde C; Vigo D; Voorspoels W; Wang A; Wong S; Nock M; Kessler R; World Mental Health - International College Student collaborators
    Background. Non-suicidal self-injury (NSSI) is associated with mental disorders, yet work regarding the direction of this association is inconsistent. We examined the prevalence, comorbidity, time–order associations with mental disorders, and sex differences in sporadic and repetitive NSSI among emerging adults. Methods. We used survey data from n = 72,288 first-year college students as part of the World Mental Health-International College Student Survey Initiative (WMH-ICS) to explore time–order associations between onset of NSSI and mental disorders, based on retrospective age-of-onset reports using discrete-time survival models. We distinguished between sporadic (1–5 lifetime episodes) and repetitive (≥6 lifetime episodes) NSSI in relation to DSM-5 mood, anxiety, and externalizing disorders. Results. We estimated a lifetime NSSI rate of 24.5%, with approximately half reporting sporadic NSSI and half repetitive NSSI. The time–order associations between onset of NSSI and mental disorders were bidirectional, but mental disorders were stronger predictors of the onset of NSSI (median RR = 1.94) than vice versa (median RR = 1.58). These associations were stronger among individuals engaging in repetitive rather than sporadic NSSI. While associations between NSSI and mental disorders generally did not differ by sex, repetitive NSSI was a stronger predictor for the onset of subsequent substance use disorders among females compared to males. Most mental disorders marginally increased the risk for persistent repetitive NSSI (median RR = 1.23). Conclusions. Our findings offer unique insights into the temporal order between NSSI and mental disorders. Further work exploring the mechanism underlying these associations will pave the way for early identification and intervention of both NSSI and mental disorders.

    Migrant top management team and corporate innovation: Evidence from China
    (John Wiley and Sons Australia, Ltd on behalf of Accounting and Finance Association of Australia and New Zealand, 2025-09-02) Liu Y; Habib A; Huang HJ
    This study explores the association between top management teams (TMT) comprised of migrant managers (migrant TMT) and corporate innovation. Using hand-collected data for a sample of Chinese A-share listed firms spanning the period 2008–2020, we find a positive and significant association between a migrant TMT and corporate innovation. Our results remain robust to a set of endogeneity tests, including entropy-balanced regression and instrumental variable regression. We then show that real earnings management and risk-taking are the channels through which the positive relationship between migrant TMTs and corporate innovation manifests itself: migrant TMTs engage less in real earnings management and are more likely to take risks. Finally, we find that the positive relationship between migrant TMTs and corporate innovation is more pronounced in state-owned firms and remains significant in both high- and low-cultural diversity regions, suggesting that the observed effect is not primarily driven by cultural adaptability but reflects a robust migration-driven mechanism. Our findings contribute to the literature by providing novel evidence on how a migrant TMT affects corporate decision-making.

    The Role of Agriculture Cooperatives in Green Agri-Food Value Chains in China: Cases in Shandong Province
    (MDPI (Basel, Switzerland), 2025-08-14) Liu Y; Garnevska E; Shadbolt N; El Bilali H
    While escalating environment and food safety challenges underscore the need for sustainable agri-food systems, promoting green agri-food production provides a promising pathway. The green agri-food value chain integrates green agri-food production with coordinated value-adding activities across the value chain. In developing such value chains, agricultural cooperatives emerge as a key player. This research integrates sustainability and value chain theories, aiming to study the role of China’s cooperatives in enabling green production and green value chains. It used qualitative methodology and interviews with management and members of three green vegetable cooperatives in Shandong Province, China, to offer an initial examination into this research area. The findings reveal that cooperatives play an important role in the green vegetable value chain and have a different level of vertical integration, with some having control over the whole value chain from input supply to retail. They also provide essential input, technical, and market support to enable green vegetable production and facilitate various value-adding activities. The study offers valuable insights into recommendations for enhancing value addition and facilitating green value chains. It also holds practical implications for practitioners and policymakers to strengthen cooperative development in China as an important intermediary for advancing agriculture sustainability.

    (Elsevier B V, 2025-09-01) Roest AM; de Vries YA; Pozuelo JR; Petukhova MV; Lee S; Sampson NA; Albor Y; Alhadi AN; Alonso J; Al-Saud N; Altwaijri Y; Andersson C; Atwoli L; Auerbach RP; Muaka CA; Báez-Mansur PM; Ballester L; Bantjes J; Baumeister H; Bendtsen M; Benjet C; Berman AH; Bruffaerts R; Carrasco P; Chan SCN; Cohut I; Couder MAC; Crockett MA; Cuijpers P; David OA; Dong D; Ebert DD; Gaete J; Forero CG; Gili M; Gutiérrez-García R; Haro JM; Hasking P; Hunt X; Husky MM; Jaguga F; Langer ÁI; Léniz I; Liu Y; Mac-Ginty S; Martínez V; McLafferty M; Miranda A; Monroy-Velasco IR; Murray EK; Musyoka CM; Nedelcea C; Núñez D; O'Neill SM; Piqueras JA; Popescu CA; Prescivalli AP; Rapsey C; Robinson K; Rodriguez-Jimenez T; Saal W; Siu O-L; Stein DJ; Struijs SY; Tomoiaga CT; Valdés-García KP; Vargas-Contreras E; Vigo DV; Wang AY; Wong SYS; Kessler RC; World Mental Health International College Student collaborators
    Background: Mental disorders are highly prevalent among students worldwide. This study aims to examine comorbidity and temporal associations between mental disorders among students. Methods: The study included 72,288 students from 18 countries as part of the World Mental Health International College Student (WMH-ICS) Initiative, with cross-sectional data collected between 2017 and 2023. Screening for common DSM-5 disorders was conducted using validated screening measures. Latent variables were examined using exploratory principal axis factor analysis on a correlation matrix among the lifetime mental disorders. Based on age-of-onset information, multivariable poisson regression models were used to examine associations of prior disorders with the first onset of other disorders. Results: 27.0 % of students screened positive for only one lifetime disorder, 17.1 % for two, 10.9 % for three, and 10.6 % for 4+ disorders. In the factor analysis, three latent variables were found, comprising: internalizing disorders (generalized anxiety disorder, major depressive episode, post-traumatic stress disorder, and panic disorder), substance use disorders (drug use disorder and alcohol use disorder), and externalizing disorders (attention deficit/hyperactivity disorder and mania/hypomania). Prior internalizing and externalizing disorders were associated with the subsequent first onset of all other disorders with risk ratios ranging from 1.5–7.5. Substance use disorders were less consistently associated with the subsequent first onset of other disorders, but alcohol use disorder was associated with the first onset of drug use disorder and vice versa. Conclusions: Mental disorder comorbidity is common among students, and students with disorders across the internalizing and externalizing spectrum have an increased risk of future mental disorder comorbidities.

    (Elsevier B V, 2025-08-01) Mortier P; Yang X; Altwaijri YA; Holdcraft JA; Lee S; Sampson NA; Albor Y; Alhadi AN; Alonso J; Al-Saud NK; Andersson C; Atwoli L; Auerbach RP; Muaka CA; Báez-Mansur PM; Ballester L; Bantjes J; Baumeister H; Bendtsen M; Benjet C; Berman AH; Bruffaerts R; Carrasco P; Chan SCN; Cohut I; Covarrubias Díaz Couder MA; Crockett MA; Cuijpers P; David OA; Dong D; Ebert DD; Gaete J; Felez-Nobrega M; García Forero C; Gili M; Gutiérrez-García RA; Haro JM; Hasking P; Hunt X; Husky MM; Jaguga F; Jansen L; Langer ÁI; Liu Y; Mac-Ginty S; Martínez V; Mason A; Mathai M; McLafferty M; Miranda-Mendizabal A; Murray EK; Musyoka CM; O'Neill SM; Papasteri CC; Piqueras JA; Popescu CA; Rapsey C; Robinson K; Rodriguez-Jimenez T; Scarf D; Siu O-L; Stein DJ; Struijs SY; Tomoiaga CT; Valdés-García KP; Vereecke S; Vigo DV; Wang AY; Wong SYS; Kessler RC; World Mental Health International College Student collaborators
    Objective: To investigate the associations of demographic variables, childhood adversities (CAs), and mental disorders (MDx) with onset, transition, and persistence of suicidal thoughts and behaviors (STB) among first-year university students. Method: Poisson regression models within a discrete-time survival framework were constructed using web-based self-report survey data from 72,288 incoming university students across 18 countries (response rate=20.9%; median age=19 years, 57.9% female, 1.4% transgender, 21.0% non-heterosexual). These models examined the associations of four demographic variables, five CAs, and eight MDx with STB outcomes. Results: Lifetime prevalence of suicidal ideation, plans, and attempts was 47.0%, 26.0%, and 9.6%, respectively; 12-month estimates were 30.6%, 14.0%, and 2.3%. In unadjusted analyses, associations were strongest between lifetime onset of suicidal ideation and CAs (RR range 4.4–7.0), particularly parental psychopathology (relative risk [RR]=7.0 [95% CI 6.5–7.7]), followed by MDx (RR range 1.3–3.0). Of the demographic subgroups, transgender students had highest risk of STB (lifetime ideation onset RR=2.4 [2.3–2.6]; ideation-to-attempt transition RR=1.5 [1.3–1.8]). In fully adjusted models, strongest predictors of lifetime ideation onset were emotional abuse (RR=2.1 [1.9–2.2]), major depressive disorder (RR=2.0 [1.9–2.1]), and bipolar disorder (RR=1.8 [1.6–2.0]). Ideation-to-attempt transition remained most strongly associated with panic disorder (RR=1.5 [1.3–1.7]), bipolar disorder (RR=1.4 [1.2–1.7]), and sexual abuse (RR=1.4 [1.2–1.7]). Most predictors were significantly but weakly associated with persistence of ideation and plan, while only physical abuse remained associated with repeated suicide attempts (RR=1.3 [1.0–1.8]). Conclusion: CAs and MDx are strong predictors of both onset of and transition within the STB spectrum, underscoring the importance of implementing early-life prevention interventions.

    Predicting the replicability of social and behavioural science claims in COVID-19 preprints
    (Springer Nature Limited, 2024-12-20) Marcoci A; Wilkinson DP; Vercammen A; Wintle BC; Abatayo AL; Baskin E; Berkman H; Buchanan EM; Capitán S; Capitán T; Chan G; Cheng KJG; Coupé T; Dryhurst S; Duan J; Edlund JE; Errington TM; Fedor A; Fidler F; Field JG; Fox N; Fraser H; Freeman ALJ; Hanea A; Holzmeister F; Hong S; Huggins R; Huntington-Klein N; Johannesson M; Jones AM; Kapoor H; Kerr J; Kline Struhl M; Kołczyńska M; Liu Y; Loomas Z; Luis B; Méndez E; Miske O; Mody F; Nast C; Nosek BA; Simon Parsons E; Pfeiffer T; Reed WR; Roozenbeek J; Schlyfestone AR; Schneider CR; Soh A; Song Z; Tagat A; Tutor M; Tyner AH; Urbanska K; van der Linden S
    Replications are important for assessing the reliability of published findings. However, they are costly, and it is infeasible to replicate everything. Accurate, fast, lower-cost alternatives such as eliciting predictions could accelerate assessment for rapid policy implementation in a crisis and help guide a more efficient allocation of scarce replication resources. We elicited judgements from participants on 100 claims from preprints about an emerging area of research (COVID-19 pandemic) using an interactive structured elicitation protocol, and we conducted 29 new high-powered replications. After interacting with their peers, participant groups with lower task expertise ('beginners') updated their estimates and confidence in their judgements significantly more than groups with greater task expertise ('experienced'). For experienced individuals, the average accuracy was 0.57 (95% CI: [0.53, 0.61]) after interaction, and they correctly classified 61% of claims; beginners' average accuracy was 0.58 (95% CI: [0.54, 0.62]), correctly classifying 69% of claims. The difference in accuracy between groups was not statistically significant and their judgements on the full set of claims were correlated (r(98) = 0.48, P < 0.001). These results suggest that both beginners and more-experienced participants using a structured process have some ability to make better-than-chance predictions about the reliability of 'fast science' under conditions of high uncertainty. However, given the importance of such assessments for making evidence-based critical decisions in a crisis, more research is required to understand who the right experts in forecasting replicability are and how their judgements ought to be elicited.

    Large-scale synthesis of N-doped carbon capsules supporting atomically dispersed iron for efficient oxygen reduction reaction electrocatalysis
    (Elsevier B.V. on behalf of Nankai University, 2022-05-17) Yang H; Liu Y; Liu X; Wang X; Tian H; Waterhouse GIN; Kruger PE; Telfer SG; Ma S
    The large-scale synthesis of platinum-free electrocatalysts for the oxygen reduction reaction (ORR) remains a grand challenge. We report the large-scale production of stable and active ORR electrocatalysts based on iron, an earth-abundant element. A core–shell zeolitic imidazolate framework–tannic acid coordination polymer composite (ZIF-8@K-TA) was utilized as the catalyst precursor, which was transformed into iron atoms dispersed in hollow porous nitrogen-doped carbon capsules (H-Fe-Nx-C) through ion exchange and pyrolysis. H-Fe-Nx-C features site-isolated single-atom iron centers coordinated to nitrogen in graphitic layers, high levels of nitrogen doping, and high permeability to incoming gases. Benefiting from these characteristics, H-Fe-Nx-C demonstrated efficient electrocatalytic activity (E1/2 ​= ​0.92 ​V, vs. RHE) and stability towards the ORR in both alkaline and acidic media. In ORR performance, it surpassed the majority of recently reported Fe-N-C catalysts and the standard Pt/C catalyst. In addition, H-Fe-Nx-C showed outstanding tolerance to methanol.

    Nphos: Database and Predictor of Protein N-phosphorylation.
    (Oxford University Press, 2024-04-10) Zhao M-X; Ding R-F; Chen Q; Meng J; Li F; Fu S; Huang B; Liu Y; Ji Z-L; Zhao Y; Xue Y
    Protein N-phosphorylation is widely present in nature and participates in various biological processes. However, current knowledge on N-phosphorylation is extremely limited compared to that on O-phosphorylation. In this study, we collected 11,710 experimentally verified N-phosphosites of 7344 proteins from 39 species and subsequently constructed the database Nphos to share up-to-date information on protein N-phosphorylation. Upon these substantial data, we characterized the sequential and structural features of protein N-phosphorylation. Moreover, after comparing hundreds of learning models, we chose and optimized gradient boosting decision tree (GBDT) models to predict three types of human N-phosphorylation, achieving mean area under the receiver operating characteristic curve (AUC) values of 90.56%, 91.24%, and 92.01% for pHis, pLys, and pArg, respectively. Meanwhile, we discovered 488,825 distinct N-phosphosites in the human proteome. The models were also deployed in Nphos for interactive N-phosphosite prediction. In summary, this work provides new insights and points for both flexible and focused investigations of N-phosphorylation. It will also facilitate a deeper and more systematic understanding of protein N-phosphorylation modification by providing a data and technical foundation. Nphos is freely available at http://www.bio-add.org/Nphos/ and http://ppodd.org.cn/Nphos/.

    The impact of heat-set milk protein gel textures modified by pH on circulating amino acid appearance and gastric function in healthy female adults: a randomised controlled trial.
    (Royal Society of Chemistry, 2024-05-21) Milan AM; Menting GGA; Barnett MPG; Liu Y; McNabb WC; Roy NC; Hutchings SC; Mungure T; Weeks M; Li S; Hort J; Calder S; O'Grady G; Mithen RF
    Modification of dairy proteins during processing impacts structural assemblies, influencing textural and nutritional properties of dairy products, and release and availability of amino acids during digestion. By modifying only pH, acid heat-set bovine dairy gels with divergent textural properties were developed to alter protein digestion. In vitro assay confirmed faster digestion of protein from a firm gel (pH 5.65) versus a soft gel (pH 6.55). We hypothesised that firm gel (FIRM-G; pH 5.6) would result in greater indispensable amino acid (IAA) appearance in circulation over 5 h and corresponding differences in gastric myoelectrical activity relative to soft gel (SOFT-G; pH 6.2). In a randomised, single-blind cross-over trial, healthy females (n = 20) consumed 150 g of each gel; plasma amino acid appearance was assessed over 5 hours. Iso-nitrogenous, iso-caloric gels were prepared from identical mixtures of bovine milk and whey protein concentrates; providing 17.7 g (FIRM-G) and 18.9 g (SOFT-G) of protein per serving. Secondary outcomes included gastric myoelectrical activity measured by body surface gastric mapping, glycaemic, triglyceridaemic, and subjective appetite and digestive responses. Overall plasma IAA (area under the curve) did not differ between gels. However, plasma IAA concentrations were higher, and increased more rapidly over time after SOFT-G compared with FIRM-G (1455 ± 53 versus 1350 ± 62 μmol L-1 at 30 min, p = 0.024). Similarly, total, branched-chain and dispensable amino acids were higher at 30 min with SOFT-G than FIRM-G (total: 3939 ± 97 versus 3702 ± 127 μmol L-1, p = 0.014; branched-chain: 677 ± 30 versus 619 ± 34 μmol L-1, p = 0.047; dispensable: 2334 ± 53 versus 2210 ± 76 μmol L-1, p = 0.032). All other measured parameters were similar between gels. Peak postprandial aminoacidaemia was higher and faster following ingestion of SOFT-G. Customised plasma amino acid appearance from dairy is achievable by altering gel coagulum structure using pH during processing and may have minimal influence on related postprandial responses, with implications for targeting food design for optimal health. The Clinical Trial Registry number is ACTRN12622001418763 (https://www.anzctr.org.au) registered November 7, 2022.

    An Evaluation of Different Digestion Methods for the Quantitation of Inorganic Elements in Human Hair Using ICP-MS.
    (John Wiley and Sons, 2022-12-01) Liu Y; Yang Y; Xia Y-Y; de Seymour JV; Zhao D-Z; Li Y-M; Zhang H; Han T-L; Kowalski R
    The inorganic elements have unique properties in biochemical processes in humans. An increasing number of pathologies have been associated with essential element ions, such as lead, mercury, and cadmium. Hair has become an attractive clinical specimen for studying the longitudinal exposure to elements from the external environment. Inductively coupled plasma-mass spectrometry (ICP-MS) coupled with nitric acid (HNO3) digestion is the most common approach for determining inorganic elements from human hair. This study aims to optimize the digestion method for the absolute quantitation of 52 elements using ICP-MS, for a large cohort study in human hair. Five different HNO3 (65%) digestion methods were investigated and evaluated for their internal standard solution stability, reproducibility, element coverage, and standard solution recovery efficiency, namely, room temperature for 24 h (RT), 90°C for 4 h (T90), ultrasonic-assisted digestion (UltraS), programmed digestion of microwave digestion (MicroD), and ordinary microwave oven digestion (O-MicroD). Our results demonstrated that O-MicroD, MicroD, and RT were the best performing digestion methods for coefficient of variation (CV) scores, coverage, and recovery efficiency, respectively. In particular, the O-MicroD method detected multiple elements in a small quantity of hair (3 mg), with minimum nitric acid usage (200 μl) and a short digestion time (30 min). The O-MicroD method had excellent reproducibility, as demonstrated by a continuous thousand injections of hair samples with three internal standards (CV: 103Rh = 3.59%, 115In = 3.61%, and 209Bi = 6.31%). Future studies of the elemental content of hair should carefully select their digestion method to meet the primary purpose of their study.
