The allocation of carbon resources in marine capture fisheries.

Marine fishery carbon emissions play a significant role in agricultural carbon emissions, making resource allocation a crucial topic for the overall marine ecological protection. This paper evaluates the dynamic iteration method as a research approach with the factors of resource allocation consisting of value assessment, optimization objective, difference between value assessment and objective, and optimization calculation. The paper selects the shadow price from the Super-SBM model as the judgment function for the goal value, aiming for the fairness criterion. From an equity standpoint, the allocation of carbon resources in marine capture fisheries proves to be unreasonable. The fishery model exhibits an excessive supply of carbon resources, resulting in wastage, while the green fishery model faces a relatively limited supply, with a focus on energy conservation and environmental protection. To address this issue, this paper proposes a new method and discusses the corrective results. This result shows that the stabilization point achieved is a short-term equilibrium rather than a long-term one. By rectifying the social contradiction of profit-oriented approaches, this research provides a fresh perspective for economic studies and applications, particularly in industrial layout and resource utilization optimization.

[Study on HIV related stigma and discrimination among people living with HIV/AIDS and their family members].

OBJECTIVE: To understand the perceived stigma and discrimination and received stigma and discrimination as well as the differences and reasons of them among people living with HIV/AIDS and their family members. METHODS: 307 people were investigated and 117 of which were HIV/AIDS and the others were their family members. Face to face interview was carried out. RESULTS: HIV/AIDS and their family were living in the social environment rounded by stigma and discrimination. Stigma and discrimination could be divided into perceived stigma and discrimination and received stigma and discrimination, and these two kinds of stigma and discrimination were statistically significant different between HIV/AIDS and their family members (t = -12.540, P = 0.000), and the perceived stigma and discrimination was more serious than received stigma and discrimination. The perceived stigma and discrimination were related to their self-efficacy (OR = 0.558, P = 0.041), family APGAR (OR = 0.650, P = 0.027), infected with HIV or not (OR = 2.116, P = 0.004). The received stigma and discrimination were related to their self-efficacy (OR = 0.468, P = 0.028), family APGAR (OR = 0.427, P = 0.000) whether infected by HIV (OR = 3.412, P = 0.001). CONCLUSION: Stigma and discrimination did exist in the environment where HIV/AIDS and their family lived, suggesting that it was necessary to develop a series of policies and measures to fight against stigma and discrimination.

[SCL-90 test result on the left-behind children in rural area: a meta-analysis].

OBJECTIVE: To evaluate the mental health status of the left-behind children in rural area. METHODS: A computerized literature search was carried out in PubMed, CBM (Chinese Biomedical Database), CNKI (Chinese National Knowledge Infrastructure), Wanfang (Chinese), VIP (Chinese) databases and so on, to collect articles published between 1994 and 2009 concerning the mental health status of the left-behind children in rural area. We also checked the reference lists of relevant articles. The study type was cross-sectional study and the survey instrument was SCL-90. Meta-analyses were performed to assess 9 dimensions, i.e., compulsion, depression, anxiety, etc. Fixed and random effect models were employed to combine results after a heterogeneity test, with weighted mean difference (WMD) used as the indicator of intervention effect. RESULTS: In total, 39 literatures were searched and 8 literatures were included. Meta-analyses showed that there were statistical significance with WMD of 8 dimensions (P < 0.05) except "compulsion". When the results from the Meta-analyses were stratified according to sampling methods, the outcomes showed that there were statistical significance with WMD of 7 dimensions (P < 0.05) except "hostility" and "paranoid" by using cluster sampling, and there were statistical significance with WMD of 8 dimensions (P < 0.05) except "compulsion" by using random sampling. The sensitivity analysis did not change the pattern of results. CONCLUSION: There were more serious mental health problems in the left-behind children than other children in rural area.
