Volunteering is playing an increasingly bigger role in social services and schools both in Western settings and in the Hong Kong Chinese context. The demand for volunteers in the sector of social services is continually increasing (Sherr 2008). Little is known about the willingness of secondary school students to participate in future volunteering in Hong Kong. This study attempts to explore the phenomenon of youth volunteering through the theory of planned behavior and Personal and Social Responsibility, and identifies prior experience in community service as a main predictor of the willingness of the students to participate in future volunteering. A total of 1046 students from seven secondary schools in Hong Kong completed a structured questionnaire. Social workers, teachers, and volunteer managers could benefit from this study as they could foster students’ willingness to volunteer after graduation by actively engaging them in community service programs early on in a specific time in their life.

It is well known that measuring the noneconomic outcomes produced by social economy organizations is fairly difficult and complex. Usually, social economy organizations feature participatory and democratic decision-making processes that help create social capital and relational goods, and they are interested in social integration; accordingly, they tend to create an organizational culture that encourages their workers to contribute to local communities. Therefore, the hypothesis that the increased activities of social economy organizations have a causal effect on the subjective well-being of the people living near those organizations is highly plausible. In this paper, we estimate the causal effect and attempt to test the hypothesis statistically by using a dataset called the “Seoul Survey,” which provides observations on the subjective well-being of 45,496 citizens living in Seoul and the size of social economy organizations. Controlling for variables at the district level and the appropriate socioeconomic characteristics of each individual in the dataset, we find that the size of social organizations is highly significant.

HIV civil society advocacy in Vietnam is shaped by a unique fusion of historic and contemporary influences, resulting in nuanced ways in which advocacy is practised. In this study, we interviewed representatives from civil society, the Government of Vietnam, international NGOs, multilateral and research organisations and commercial consultancies to identify the influences on advocacy practice today. Aspects of Confucianism, Buddhism, Communism and changes to international funding were all identified as shaping HIV civil society policy advocacy practice directed towards government. These influences have resulted in a strong respect for hierarchy, non-confrontational and collaborative working relationships between civil society and the government, decision-making by consensus and changes in advocacy practice corresponding to fluctuations in international funding. This study shows how, as civil society continues to develop its role in the HIV sector in Vietnam, it is critical to understand these complex influences so that program designers, funders and evaluators can appropriately support HIV civil society policy advocacy.

This study systematically evaluates the effects of probiotic interventions on gut microbiota and clinical outcomes in diabetic patients to determine the optimal target population and conditions for effective use, with an emphasis on precision treatment. A comprehensive search was performed across PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Internet (CNKI), and Wanfang databases until April 2024. Randomized controlled trials (RCTs) assessing probiotics as adjunctive therapy for diabetes were included. The control group received standard care, and the intervention group received probiotics alongside standard care. Data were managed with Endnote and Excel, and analyses were conducted using Revman 5.3 and Stata 16. Twelve RCTs involving 1,113 participants were included. Probiotics significantly increased fecal Lactobacillus (standardized mean difference (SMD) 1.42, P < 0.0001, I2 = 95%) and Bifidobacterium levels (SMD 1.27, P < 0.0001, I² = 90%) and reduced fasting plasma glucose (SMD -0.35, P = 0.004). Subgroup analysis showed that shorter intervention durations (≤3 months) improved FPG, HbA1c, and Bifidobacterium levels, while younger patients (≤60 years) experienced the most significant improvements in Bifidobacterium levels. In conclusion, probiotics improve gut microbiota and clinical outcomes in diabetic patients, with intervention duration and patient age as key factors influencing treatment effectiveness.

Let $S_g$ denote the genus g closed orientable surface. A coherent filling pair of simple closed curves, $(\alpha,\beta)$ in $S_g$, is a filling pair that has its geometric intersection number equal to the absolute value of its algebraic intersection number. A minimally intersecting filling pair, $(\alpha,\beta)$ in $S_g$, is one whose intersection number is the minimal among all filling pairs of $S_g$. In this paper, we give a simple geometric procedure for constructing minimally intersecting coherent filling pairs on $S_g, \ g \geq 3,$ from the starting point of a coherent filling pair of curves on a torus. Coherent filling pairs have a natural correspondence to square-tiled surfaces, or origamis, and we discuss the origami obtained from the construction.

The famous Sidorenko’s conjecture asserts that for every bipartite graph $H$, the number of homomorphisms from $H$ to a graph $G$ with given edge density is minimised when $G$ is pseudorandom. We prove that for any graph $H$, a graph obtained from replacing edges of $H$ by generalised theta graphs consisting of even paths satisfies Sidorenko’s conjecture, provided a certain divisibility condition on the number of paths. To achieve this, we prove unconditionally that bipartite graphs obtained from replacing each edge of a complete graph with a generalised theta graph satisfy Sidorenko’s conjecture, which extends a result of Conlon, Kim, Lee and Lee [J. Lond. Math. Soc., 2018].

African swine fever (ASF) is a highly contagious animal disease caused by African swine fever virus (ASFV). It is listed by the World Organization for Animal Health (WOAH) as an animal disease subject to statutory reporting. ASFV, a large, enveloped double-stranded DNA virus with high genomic complexity, exhibits a case fatality rate of up to 100%, posing a significant threat to the global pig industry and food safety. To date, the absence of a safe commercial ASFV vaccine primarily stems from challenges in identifying immunogenic viral antigens, insufficient characterization of ASFV pathogenesis, and limited understanding of the virus’s immune evasion mechanisms. Here, we review the pathogenic characteristics (morphological structure, clinical symptoms, and epidemiological characteristics), molecular biological characteristics, and infection mechanism of ASFV, as well as the immune response mechanism, vaccine research, and the latest information on ASFV in other areas. This review will be in favour of understanding the current state of knowledge of ASF and developing effective vaccines to control this disease.

This systematic review examined the associations of dietary factors such as nutrients, food intake, dietary patterns and dietary biomarkers with structural and functional brain MRI biomarkers, focusing on macrostructural, microstructural, lesion and perfusion measures, and functional activity/connectivity. Articles published in English were systematically searched in PubMed, Embase and PsycInfo up to 19 July 2024. A total of thirty-eight prospective cohort studies (twenty-three cross-sectional and fifteen longitudinal analyses) and thirteen intervention studies were included. Cross-sectional analyses revealed heterogenous associations: baked fish correlated with larger hippocampal volumes (β = 0·21), while oily fish, dairy products and tofu adversely related to ventricle grade. Pro-inflammatory dietary patterns were positively associated with silent infarct risk (DII Q4 v. Q1, OR = 1·77), whereas anti-inflammatory patterns tended to favour brain preservation. Longitudinal studies demonstrated more consistent protective associations: green tea consumption (+100 mL/d) reduced hippocampal atrophy by 0·024%/year, prudent dietary patterns preserved +203 mm3 left hippocampal volume over 4 years and higher plasma carotenoids decreased medial temporal lobe loss by 0·02 cm3/year. However, null findings were common across multiple dietary factors. Interventions showed limited structural benefits (effective in only two of six studies), while polyphenol-rich supplements more consistently improved cerebral perfusion and functional connectivity. Longitudinal and intervention studies demonstrated more consistent patterns than cross-sectional analyses; however, current evidence remains limited for clinical translation. Findings from cross-sectional analyses, despite being from prospective cohorts, require careful interpretation. Further replication across diverse populations and standardised long-term studies are needed before translating these associations into clinical practice.

Judges in Vietnam have increasingly been called upon by the state and society to resolve new social and economic problems. However, the expansion of judicial authority presents a problem for Vietnam’s authoritarian government, which wants courts that can resolve social problems without challenging state interests. This study draws on empirical research to explore whether judges in Vietnam’s authoritarian polity can harness legal reasoning to extend their authority. It uses a novel theoretical framework based on systems theory to understand how judges determine who is entitled to benefit from the law, which norms are appropriate to particular cases, and how such norms might direct them to reach decisions. Data from case studies and interviews with judges reveal that courts in Vietnam are increasingly using legal reasoning to manage the interaction between legal and extralegal norms, which is a decision-making process with the potential to expand judicial authority over socially significant disputes.

Alcohol use disorder (AUD) is a chronic condition that impairs health and function. Cognitive behavioral therapy (CBT) is an evidence-based treatment traditionally delivered face-to-face. Recently, digital CBT delivered online has gained prominence because of access barriers and user preferences. Although many digital CBT studies have emerged, few systematic reviews have directly compared digital and face-to-face CBT in adults with AUD. This systematic review and meta-analysis aimed to evaluate their comparative effectiveness. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, a comprehensive search identified 25 randomized controlled trials (n = 2,065) comparing these formats. A random-effects meta-analysis evaluated pre- and post-effectiveness by calculating the standardized mean change using raw score standardization (SMCR). For drinking quantity, digital CBT showed a significant pre–post effect (SMCR = 1.21, 95% confidence interval [CI]: 0.38 to 2.04; p = 0.004). Face-to-face CBT showed no overall significant effect (SMCR = 0.69, 95% CI: −0.16 to 1.53; p = 0.110). However, subgroup analysis of face-to-face trials showed significance for active treatment (SMCR = 1.09), but a nonsignificant negative effect for relapse prevention (SMCR = −0.72). For drinking frequency, both interventions yielded statistically significant effects; however, face-to-face CBT demonstrated a stronger effect (SMCR = 1.02, 95% CI: 0.30 to 1.74; p = 0.006) than digital CBT (SMCR = 0.54, 95% CI: 0.29 to 0.79; p < 0.001). Forest plots were generated, and Begg’s test was used to assess publication bias.

Butachlor is a herbicide extensively employed in rice (Oryza sativa L.) cultivation but historically under-investigated for its toxicological impacts on terrestrial vegetation. This study examines the dose-dependent effects of butachlor on the germination and antioxidant defense mechanisms in the seeds of Asian tape grass [Vallisneria natans (Lour.) H. Hara], an important submerged plant species widely distributed in the agricultural ponds. In a hydroponic setup, seeds were exposed to four concentrations of butachlor (0, 20, 200, and 2,000 μg ai L−1), and cultivated under controlled light conditions to quantify germination rates and assess oxidative stress responses. Our findings showed that butachlor concentrations up to 20 μg L−1 had no effect on the germination rate of V. natans seeds, while germination rates decreased by 6.0% and 8.7% at 200 and 2,000 μg L−1, respectively. At 2,000 μg L−1, malondialdehyde (MDA) content increased by 5.7 nmol g−1 FW, and catalase (CAT) activity declined by 21%, indicating oxidative damage. Additionally, the antioxidants proline (Pro) and glutathione (GSH) were upregulated under 20 μg L−1 butachlor treatment after 12 h, contributing to reactive oxygen species (ROS) scavenging and cellular stability. This study highlights the nuanced interactions between butachlor exposure and the antioxidant defenses in V. natans, providing valuable insights into the ecological impacts of herbicide pollution. Understanding these interactions is crucial for development of sustainable agricultural practices and management of herbicide resistance in aquatic systems.
