Abstract

This study investigates the intricate relationships between flood disaster risk perception (RP), attitudes(ATT), subjective norms(SN), and participation in flood prevention activities(IPF), emphasizing the mediating roles of self-efficacy(SE) and bonding social capital(BSC). The research in Freetown, Sierra Leone, involved 702 participants, providing a diverse socio-demographic snapshot crucial for understanding community-based flood risk management. Data analysis revealed that demographic factors like age, gender, education, and income significantly influence flood risk perceptions and mitigation behaviors. Additionally, subjective norms were found to substantially impact both self-efficacy and bonding social capital, affecting participation in flood prevention activities. The study also explored the role of community dynamics and social norms in shaping risk perceptions and intentions to engage in flood risk prevention. It was observed that higher self-efficacy and more robust community bonds lead to increased participation in flood mitigation efforts. The findings offer valuable insights into flood prevention behavior's psychological and social drivers and highlight the importance of community-focused strategies in enhancing flood resilience. The study contributes to the broader understanding of flood risk management in urban settings, particularly in developing countries, and underscores the need for policies and practices that foster individual empowerment and collective community action.

Abstract

The occurrence of Maillard reaction in heated Torreya grandis cv. Merrilli seed oil was verified by detecting browning index and the contents of the Maillard reaction products (MRPs) 3-deoxyglucosone, methylglyoxal and 5-(hydroxymethyl)furfural, and the effects of the MRPs on the quantification of total phenolics using the Folin-Ciocalteu and Fast Blue BB assays were explored. The Folin-Ciocalteu assay showed that the content of total phenolics in the oil increased after treatment at 150 ℃ for 90 to 120 min, while the Fast Blue BB assay showed the opposite result. It was also observed that the absorbance of the oil at a wavelength of 294 nm increased after long-term low-temperature or high-temperature heat treatment. 3-Deoxyglucosone (0.21–0.47 μg/g) and 5-(hydroxymethyl)furfural (0.06–0.40 μg/g) were detected only in the 150 ℃ treated oil, while methylglyoxal (0.67–1.73 μg/g) existed in both oil samples. In the Folin-Ciocalteu assay, the absorbance at a wavelength of 765 nm of 3-deoxyglucosone and methylglyoxal linearly increased with an increase in their concentrations, and the decreasing order of the absorbance of the MRPs at the same concentration was 3-deoxyglucosone > methylglyoxal > 5-(hydroxymethyl)furfural. In the presence of 3-deoxyglucosone, the Folin-Ciocalteu result was greater than the actual value, and the degree of interference was not related to the content of total phenolics in samples, but instead was positively correlated with the concentration of 3-deoxyglucosone. In the Fast Blue BB assay, there was no significant difference in absorbance at 420 nm among the three MRPs. For food matrices prone to the formation of 3-deoxyglucosone and methylglyoxal during processing, the Fast Blue BB assay can be selected instead of the Folin-Ciocalteu assay to mitigate the interferences from the two substances in the quantification of total phenolics.
