Negative life events, sleep quality, and depression among older adults in Shandong Province, China: A conditional process analysis based on economic income.

AIM: Negative life events have been reported as a risk factor for depression. However, the mechanism between negative life events and depression is still unclear. This study aimed to explore the mediating role of sleep quality and the moderating role of economic income in the association between negative life events and depression among older adults aged 60 years and over. METHODS: A multi-stage stratified sampling method was used to select elderly individuals over 60 years old in Shandong, China, making use of the Household Health Interview Survey (2020). In total, 3868 older adults completed the measures of negative life events, sleep quality, depression, and economic income. RESULTS: Negative life events positively predicted depression among the elderly (proportion of direct effect, 55.12%), and poor sleep quality could mediate this association (proportion of indirect effect, 44.87%). Economic income played a moderating role in the relationship between negative life events, sleep quality, and depression (the first and second half of the mediating effect, the direct effect of negative life events on depression). Both effects were weaker among the elderly with higher economic incomes. CONCLUSIONS: Negative life events had positive effects on depression in older adults. Economic income moderated the direct effect of negative life events and the mediating effect (first and second half) of sleep quality on depression. When the elderly experience negative life events, interventions for improving their sleep quality and financial support could effectively prevent depression. Geriatr Gerontol Int 2024; 24: 751-757.

Effect of Organic Manure on Crop Yield, Soil Properties, and Economic Benefit in Wheat-Maize-Sunflower Rotation System, Hetao Irrigation District.

The combined application of manure and mineral fertilizer represents an effective strategy for enhancing crop yield. However, the relationship between soil fertility and crop yield remains unclear in saline-alkaline soil. Here, a 9-year field experiment (2015-2023) was conducted to investigate the effects of manure application and crop rotations on crop yield and economic efficiency as well as potential associated mechanisms in the Hetao Irrigation District. The results showed that in the third cropping rotation cycle, combined application of manure and mineral fertilizers (NPKO) caused a 6.2%, 38.9%, 65.3%, and 132.2% increase in wheat, sunflower, wheat equivalent yield, and the economic income of sunflower, respectively. The average grain yield had a positive correlation with soil organic matter and nutrient supply. This suggested that the soil organic matter had a positive effect on the crop yield due to its impact on nutrient supply. Simultaneously, the sunflower seed setting rate increased by 65.2% under NPKO. The linear regression model revealed that each additional input of 20 Mg ha-1 of manure resulted in an increase of 3.56 kg ha-1 in crop phosphorus harvest and a 0.05 Kg ha-1 increase in wheat equivalent yield compared to NPK. In conclusion, our results highlighted that manure application promotes soil properties and improves crop yield.

Applications of land surface model to economic and environmental-friendly optimization of nitrogen fertilization and irrigation.

Land surface models (LSMs) have prominent advantages for exploring the best agricultural practices in terms of both economic and environmental benefits with regard to different climate scenarios. However, their applications to optimizing fertilization and irrigation have not been well discussed because of their relatively underdeveloped crop modules. We used a CLM5-Crop LSM to optimize fertilization and irrigation schedules that follow actual agricultural practices for the cultivation of maize and wheat, as well as to explore the most economic and environmental-friendly inputs of nitrogen fertilizer and irrigation (FI), in the North China Plain (NCP), which is a typical intensive farming area. The model used the indicators of crop yield, farm gross margin (FGM), nitrogen use efficiency (NUE), water use efficiency (WUE), and soil nitrogen leaching. The results showed that the total optimal FI inputs of FGM were the highest (230 ± 75.8 kg N ha-1 and 20 ± 44.7 mm for maize; 137.5 ± 25 kg N ha-1 and 362.5 ± 47.9 mm for wheat), followed by the FIs of yield, NUE, WUE, and soil nitrogen leaching. After multi-objective optimization, the optimal FIs were 230 ± 75.8 kg N ha-1 and 20 ± 44.7 mm for maize, and 137.5 ± 25 kg N ha-1 and 387.5 ± 85.4 mm for wheat. By comparing our model-based diagnostic results with the actual inputs of FIs in the NCP, we found excessive usage of nitrogen fertilizer and irrigation during the current cultivation period of maize and wheat. The scientific collocation of fertilizer and water resources should be seriously considered for economic and environmental benefits. Overall, the optimized inputs of the FIs were in reasonable ranges, as postulated by previous studies. This result hints at the potential applications of LSMs for guiding sustainable agricultural development.

Determinants of financial inclusion in households in Peru.

The issue of financial inclusion considers access to and use of quality financial services by household members and different types of companies around the world, allowing us to reach the opportunities that the globalized world offers us. The objective of this research was to identify the socioeconomic factors that determined the inclusion of households in the financial system in Peru in the period of 2021. A quantitative approach was considered, which was non-experimental with a descriptive and correlational design and in which 81,441 pieces of data were obtained from the National Household Survey (ENAHO) of the National Institute of Statistics and Informatics, applying a logit binomial regression. It was determined that 47.02% of households were included in the financial system; 61.93% of those surveyed had their residence in the urban area; on average, respondents had incomplete secondary education; the age of the respondents on average was from 25 to 44 years; the average economic income of the household was less than $251 per month; 72.18% were represented by men as heads of the household and the rest by women; most of the respondents had a cohabiting marital status; the social conditions showed that 23.82% were in the group of being poor; and the majority of households did not have a property title. The determinants of financial inclusion in Peruvian households for 2021 were the area of residence, educational level, age of the respondent, economic income, gender of the respondent, marital status, social status, and property title.

The environmental and socioeconomic benefits of optimized fertilization for greenhouse vegetables.

China produces more than half of global vegetables with greenhouse farms contributes approximately 35 % to the country's overall vegetable supply. The average nitrogen (N) application rate of greenhouse vegetable production exceeds 2000 kg N ha-1 yr-1, considerably contributing to global agricultural GHG emissions and reactive N (Nr) losses. Optimizing the N fertilizer utilization in greenhouse vegetable production is essential for mitigating environmental pollution and promoting sustainable development nationally and globally. In this study, we estimated the N footprint (NF), social costs (SC, which includes ecosystem and human health damage costs caused by Nr losses to the environment) and net ecosystem economic income (NEEI, which balances between the fertilizers input cost, yield profit, and social costs) of different greenhouse vegetables (tomato, pakchoi, lettuce, cabbage) under farmers' practice (FP) and reduced fertilization treatment (R). Results showed that compared with FP, the NF of tomato, pakchoi, lettuce and cabbage in the R treatment decreased by 61 %, 29 %, 46 % and 36 %, respectively, and the social costs were decreased by 60 %, 48 %, 57 % and 50 %, respectively. On the regional scale, the reduction in N fertilizer use for greenhouse vegetables in Beijing only could save the fertilizer input cost by 1-5 million USD, and avoided SC would increase by 1-14 million USD. As a result, this increased the NEEI by 2-19million USD. This study has demonstrated that adopting reduced fertilization practices represents a cost-effective measure that not only ensures yields but also decrease social costs, NF, and improve the benefits to help achieve sustainable development of greenhouse vegetable production.

Mediating Effect of Filial Piety Between the Elderly's Family Resource Contribution and Their Family Power: Evidence from China.

With the development of rationalism, although the concept of filial piety is still an important factor affecting family relations, its rules have changed. Based on the resource theory and by measuring family power via the role played in family decision-making (FDM), this study explored the mediating role of filial piety norms between elderly's family resource contributions and family power in intergenerational cohabitation families in Mengzhou city, China. Using a stratified sampling method, 1,200 elderly people were recruited for data collection. Multiple linear regression analysis was used for testing. The results show that (1) the elderly still have some FDM in Chinese intergenerational cohabitation families, and the family power of elderly men is still higher than that of elderly women, which indicate that the influence of traditional patriarchal norms still exists in the family. (2) Filial piety culture mediates between the elderly's relative economic income (relative to their adult children) and their family power and also mediates the relationship of the elderly's relative educational level (relative to their adult children) and their family power. It shows that the resources of the elderly relative to their children affect the filial piety of their adult children and then affect the FDM of the elderly. The study is theoretically and practically meaningful.

Reactive nitrogen releases and nitrogen footprint during intensive vegetable production affected by partial human manure substitution.

Evaluating the sustainability of vegetable production is crucial to secure future food supply. A 2-year field study of four different vegetable crops was performed to investigate the effects of inorganic fertilizer and human manure at different ratios on vegetable yields, reactive gaseous nitrogen emissions (GNrEs), reactive nitrogen (Nr) footprint, and net ecosystem economic income (NEEI) by using life cycle analysis. Four fertilization strategies were studied, including CK (no fertilization); CF (inorganic fertilization); CHF1 (human manure /inorganic fertilizer, N ratio = 1:7); and CHF2 (human manure /inorganic fertilizer, N ratio = 1:3). Results showed that compared with CF treatment, both CHF1 and CHF2 treatments increased the N2O + NO emissions by 11.8% and 32.4% on average, while decreased the vegetable yields by 6.7% and 7.4%, respectively. Moreover, the addition of human manure increased the proportions of Nr footprint by 6.6% (CHF1) and 2.9% (CHF2) in comparison with CF treatment. However, although CHF2 treatment significantly increased the values of GNrEs and reactive gaseous nitrogen intensity (GNrI) by 8.4% and 12.5%, respectively, in relation to those in CF treatment, it still increased farmers' income by 16,404 CNY ha-1. These findings suggest that although human manure incorporation could not mitigate Nr releases, the appropriate ratio of inorganic fertilizer and human manure (CHF2) is able to improve net economic income (NEI) and NEEI during intensive vegetable production. Nevertheless, it should be further explored about the relationship between combinatorial treatment of inorganic fertilizer and human manure on Nr release mitigation in intensive vegetable production.

The mechanisms underlying the negative effect of depression on life satisfaction among the elderly: the roles of ostracism and economic income.

OBJECTIVES: Depression is prevalent among older persons, which seriously threatens their life satisfaction. This study aimed to explore the internal mechanisms by which depression influences life satisfaction among the elderly, as well as the mediating and moderating effects of ostracism and economic income, respectively, in a sample of rural older adults across China. DESIGN: This was a cross-sectional survey conducted as part of the project "Thousands of People and Hundreds of Villages (2019)." SETTING: Participants were rural older adults from 31 provincial-level administrative units across China. PARTICIPANTS: The sample composed of 1,754 participants aged 60 years and over. MEASUREMENTS: Depression was assessed with the depression subscale of the Depression Anxiety Stress Scales, life satisfaction with the Satisfaction with Life Scale, ostracism with the Ostracism Experience Scale (OES), and economic income and other control variables with related demographic scales. Moderation and mediation analyses were performed using the regression-based approach as conducted by Hayes (). RESULTS: Depression negatively predicted life satisfaction among the elderly. Ostracism played a partially mediating role between depression and life satisfaction. Economic income moderated the effect of depression and ostracism on life satisfaction: High economic income weakened the negative effect of depression on life satisfaction and enhanced the negative effect of ostracism on life satisfaction. CONCLUSION: Improving depressed elderly people's interpersonal relationships and financial support could improve their life satisfaction.

Factors of postpartum depression among teen mothers in Rwanda: a cross- sectional study.

OBJECTIVE: To identify the factors of postpartum depression among teen mothers. METHOD: A convenient sample of 120 teen mothers who were aged 15 to 19 years (M = 18.02, SD = 1.16) were recruited. Depression and its related factors were assessed with Edinburgh Postnatal Depression Scale, Eating Disorder Inventory (Body Dissatisfaction and Drive for Thinness subscales), Parental stress index (Parental distress and Parental-child dysfunctional interaction subscales), Frost Multidimensional Perfectionism Scale (parental criticism of parenting subscale) and Multidimensional Scale of Perceived Social Support. Both descriptive and analytical analyses were performed using Statistical Package for the Social Sciences (SPSS version 22). RESULTS: Results showed that 48% of sample had clinically high levels of depressive symptoms. Its associated factors were parental distress (ß = .297, t = 3.378, p = .001), weight/shape disturbances (ß = .217, t = 2.42, p = .017), economic income (ß = -.210, t = -2.32, p = .022) and parental-child dysfunctional interaction (ß = .20, t = 2.08, p = .03) among seven factors considered. CONCLUSION: Regression analyses showed that parental distress, weight/shape disturbances, economic income and parental-child dysfunctional interaction predicted unique variance associated with depression level. These findings are discussed in light of future work and the persistent need to inform prevention and treatment programs for teen mothers.

Optimizing the nitrogen application rate for maize and wheat based on yield and environment on the Northern China Plain.

Optimizing the nitrogen (N) application rate can increase crop yield while reducing the environmental risks. However, the optimal N rates vary substantially when different targets such as maximum yield or maximum economic benefit are considered. Taking the wheat-maize rotation cropping system on the North China Plain as a case study, we quantified the variation of N application rates when targeting constraints on yield, economic performance, N uptake and N utilization, by conducting field experiments between 2011 and 2013. Results showed that the optimal N application rate was highest when targeting N uptake (240kgha-1 for maize, and 326kgha-1 for wheat), followed by crop yield (208kgha-1 for maize, and 277kgha-1 for wheat) and economic income (191kgha-1 for maize, and 253kgha-1 for wheat). If environmental costs were considered, the optimal N application rates were further reduced by 20-30% compared to those when targeting maximum economic income. However, the optimal N rate, with environmental cost included, may result in soil nutrient mining under maize, and an extra input of 43kgNha-1 was needed to make the soil N balanced and maintain soil fertility in the long term. To obtain a win-win situation for both yield and environment, the optimal N rate should be controlled at 179kgha-1 for maize, which could achieve above 99.5% of maximum yield and have a favorable N balance, and at 202kgha-1 for wheat to achieve 97.4% of maximum yield, which was about 20kgNha-1 higher than that when N surplus was nil. Although these optimal N rates vary on spatial and temporal scales, they are still effective for the North China Plain where 32% of China's total maize and 45% of China's total wheat are produced. More experiments are still needed to determine the optimal N application rates in other regions. Use of these different optimal N rates would contribute to improving the sustainability of agricultural development in China.

In addition, an effect was found between the interaction of levels of income and education level, and the in strength and self-confidence. For future research, it is suggested to deepen these results on qualitative level.

Environmental and economic risks assessment under climate changes for three land uses scenarios analysis across Teshio watershed, northernmost of Japan.

Land use and climate changes affect on the economy and environment with different patterns and magnitudes in the watershed. This study used risk analysis model stochastic efficiency with respect to a function (SERF) to evaluate economic and environmental risks caused by four climate change scenarios (baseline, small-, mid- and large changes) and three land uses (paddy dominated, paddy-farmland mixture and farmland dominated for agriculture) in Teshio watershed in northern Hokkaido, Japan. Under the baseline climate conditions, the lower ranking of economic income of crop yield and higher ranking of pollutant load from agricultural land were both predicted in paddy dominated for agriculture, suggesting that the paddy dominated system caused higher risks of economic and environmental variables compared to other two land uses. Increase of temperature and precipitation increased crop yields under all three climate changes which resulted in increase of the ranking of economic income, indicating that those climate changes could reduce economic risk. The increased temperature and precipitation also accelerated mineralization of organic nutrient and nutrient leaching to river course of Teshio which resulted in increase of the ranking of pollutant load, suggesting that those climate changes could lead to more environmental risk. The rankings of economic income in mid- and large changes of climate were lower than that in small change of climate under paddy-farmland mixture and farmland dominated systems due to decrease of crop yield, suggesting that climate change led to more economic risk. In summary, the results suggested that increase in temperature and precipitation caused higher risks of both economic and environmental perspectives, and the impacts was higher than those of land use changes in the studied watershed. Those findings would help producers and watershed managers to measure the tradeoffs between environmental protection and agricultural economic development for making decision under land use and climate changes.

Relación entre la alexitimia y las respuestas psicológicas de duelo ante la pérdida de la salud en mujeres con cáncer / Relation between alexithymia and psychological responses of grief before the loss of health in women with cancer

La alexitimia no ha sido estudiada en relación con las respuestas de duelo de Kübler-Ross. Esta investigación tiene como objetivos estudiar la asociación y predecir las respuestas psicológicas de duelo con alexitimia, religiosidad, escolaridad e ingreso económico. A una muestra no probabilística de 120 mujeres con cáncer se les aplicó la escala de respuestas psicológicas de duelo ante la pérdida de la salud y la escala de alexitimia de Toronto. La alexitimia predijo mayor reacción de afecto negativo con tamaño de efecto grande, pero fue independiente de actitud positiva. Menor ingreso económico predijo mayor actitud positiva con tamaño de efecto mediano. Convicción religiosa predijo mayor actitud positiva con tamaño de efecto pequeño. Aunque práctica religiosa tuvo mayor relación que convicción religiosa, ofreció peor ajuste. Se concluye que las variables estudiadas tienen efectos significativos sobre las respuestas psicológicas de duelo...

Alexithymia has not been studied in relation to the Kübler-Ross psychological responses of grief. The aim of this research was to study the association and predict psychological responses of grief with alexithy-mia, religiosity, level of schooling, and economic income. The scale of psychological responses of grief before the loss of health and Toronto alexithymia scale were administered to a non-probability sample of 120 women with cancer. Alexithymia predicted greater negative affect reaction with a large effect size, but it was independent of positive attitude. Lower economic income predicted greater positive attitude with a medium effect size. Religious conviction predicted greater positive attitude with a small effect size. Although religious practice had a greater relationship to psychological responses of grief than to religious conviction, it offered worst fit. It is concluded that the studied variables have significant effects on the psychological responses of grief...
