Summary: This study focuses on the efficient subcritical low-acid hydrolysis of oligosaccharides from red seaweed, which have potential prebiotic properties and are sought-after functional food ingredients. The extraction of marine oligosaccharides from sustainable seaweed biomass with minimal loss is a green effort to meet the high demand for functional food globally. The optimized preparation and characterization of oligosaccharides from Eucheuma denticulatum show their potential as prebiotic ingredients for health food development.

Summary: The Eastern African region is experiencing climate changes and rising sea levels caused by global warming along with weather phenomena such as El Nino and La Nina. These changes emphasize the urgent need for appropriate adaptation responses, especially for vulnerable small islands in the region. This study examines coping and adaptation responses among coastal communities on two Zanzibar islands in Tanzania and identifies barriers to adaptation. It suggests ways to build resilience in local livelihoods and overcome barriers to climate change adaptation in the future.

Summary: Valuation problems, such as inaccuracies/variations, client influence, and the use of heuristics, are common in property valuation practice globally. Efforts to address these problems primarily focus on improving valuer conduct, but neglect market-related issues. A holistic approach categorizing problems into valuer conduct and market-related issues is recommended to effectively solve valuation challenges.

Summary: This study empirically investigates the interaction between foreign direct investment (FDI) inflows and child labor in developing countries using panel data analysis. The study finds a unidirectional causal relationship from FDI inflows to child labor in sub-Saharan Africa and Latin America, two regions with high rates of working children. No causality was observed from child labor on macroeconomic independent variables. The study also includes policy proposals to reduce or prevent child labor in multinational company subsidiaries.

Summary: This study utilizes worker-level data on job task content in developing countries to measure the ability to work-from-home, revealing low WFH ability in these countries but higher ability among educated, wage employees, and women. The measure is shown to predict actual WFH outcomes, including overall levels, variations across occupations and individual characteristics, and employment outcomes in Brazil, Costa Rica, and Peru.

Summary: This study aims to explore the determinants of farmers' participation in contract farming in Vietnam. The qualitative analysis identifies 10 original factors that affect farmers' participation, while the quantitative analysis provides empirical evidence on the impact of various factors such as female heads, firm consulting activities, firm scales, cooperative membership, and quality certifications. Cooperative membership and quality certifications are found to be the most important factors, while head education and good soil have a negative impact on farmers' participation. The study highlights the importance of understanding these factors in promoting contract farming.

Summary: Climate change and human activities have increased the vulnerability of soil and water resources in arid and semi-arid developing countries. Specific interventions are needed to address the crises of soil, water, and food insecurity, and enhance the resilience of farming systems. This research contributes to such efforts by identifying efficient interventions for restoring soil and water resources and investigating the drivers of resilient farming. The findings highlight the need for various changes and strategies to promote the adoption of climate-smart regenerative agriculture in vulnerable areas.

Summary: This study examines discretionary operations carried out by frontline forest bureaucrats in Java, Indonesia and the impact of changing political economic situations on power relations and discretionary actions. The study found that frontline forest bureaucrats exercised both creative and passive forms of discretion, attempting to balance the conflicting policy goals of forest protection and meeting local demands. However, they faced hesitation in dealing with local situations due to the increased bargaining power of locals resulting from recent democratization processes.

Summary: Research on the impact of health sector reforms on the poor and rich has grown over the past 20 years, but there is a lack of knowledge synthesis work. Health insurance is not a perfect solution to improving equity in the health sector, but certain design elements can increase the likelihood of addressing inequality in developing countries.

Summary: This study investigates the expansion of organic agriculture in Lebanon and analyzes the economic performance of organic tomato among smallholder farmers. It finds that the high cost of production and inefficient organization of the organic value chain make organic farming increasingly expensive. The study suggests a blended approach of organic farming with agro-tourism as a local solution to the sustainability of organic farming in developing countries.

Summary: This study aimed to investigate the relationships between faecal contamination and short-term climate variability across different water sources. Results showed that short-term climate variability and baseline contamination levels can explain about half the observed variability in faecal contamination, with increased contamination related to recent heavy rainfall and high temperature. Unimproved water sources such as unprotected dug wells were found to have substantially higher climate sensitivity.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
