Mandate-based and market-based mechanisms represent two primary approaches to achieving policy objectives,yet the debate over their relative effectiveness remains *** mandate-based approach is exemplified by pilot programs for low-carbon provinces and cities,referred to as“Low-Carbon Pilot Provinces/Cities”,while the market-based mechanism is reflected in pilot programs for carbon emissions trading markets,or“Carbon Trading Pilot Programs”.This paper employs event study analysis to compare the carbon emission reduction impacts of these two *** findings reveal that the Low-Carbon Pilot Provinces/Cities achieved emissions reduction primarily by curbing economic output,without significantly reducing carbon emissions *** contrast,the Carbon Trading Pilot Programs led to an increase in total carbon emissions by driving economic growth,even as they reduced carbon emissions intensity.A heterogeneity analysis further indicates that the emissions reductions observed in the Low-Carbon Pilot Provinces/Cities were predominantly concentrated in economically less-developed regions,whereas the increase in carbon emissions associated with the Carbon Trading Pilot Programs was more significant in regions with lower initial carbon emissions *** the backdrop of China’s efforts to achieve its carbon peak and neutrality goals,this paper offers valuable insights for the design of effective climate policies.

The department of Tillabéri is primarily affected by climatic phenomena, impacting crop yields, growing cycles, and consequently, the economic outcomes of agricultural operations. The objective of this study is to analyze these impacts of climate disruption on the economic performance of farms. The methodology adopted for this study combined documentary research with field surveys conducted on a sample of 250 randomly selected farmers. The analytical methods used mainly consisted of linear regression, profitability calculations, and linear programming. The findings indicate that all productions across different crops have experienced a decrease over the past 30 years. For instance, the production of millet, sorghum, and cowpea, which were respectively 812 kg/ha, 260 kg/ha, and 100 kg/ha between the last 30 and 20 years, has now dropped to 412 kg/ha, 106 kg/ha, and 46 kg/ha respectively. A negative and significant effect on agricultural net margin was observed due to variables such as flooding, drought, pest invasion in rice fields, and temperature changes. Smallholder farms show a relatively low margin (46%) to cover their fixed costs, which may indicate a risk if fixed expenses are high. Furthermore, the analysis results from linear programming reveal that farmers could achieve an additional net profit per hectare of 116,861 FCFA, 217201.5 FCFA, and 291988.2 FCFA respectively for small, medium, and large producers by managing variable costs and health-related expenses for households.

The role of copper element has been an increasingly relevant topic in recent years in the fields of human and animal health, for both the study of new drugs and innovative food and feed supplements. This metal plays an important role in the central nervous system, where it is associated with glutamatergic signaling, and it is widely involved in inflammatory processes. Thus, diseases involving copper(Ⅱ) dyshomeostasis often have neurological symptoms, as exemplified by Alzheimer's and other diseases(such as Parkinson's and Wilson's diseases). Moreover, imbalanced copper ion concentrations have also been associated with diabetes and certain types of cancer, including glioma. In this paper, we propose a comprehensive overview of recent results that show the importance of these metal ions in several pathologies, mainly Alzheimer's disease, through the lens of the development and use of copper chelators as research compounds and potential therapeutics if included in multi-target hybrid drugs. Seeing how copper homeostasis is important for the well-being of animals as well as humans, we shortly describe the state of the art regarding the effects of copper and its chelators in agriculture, livestock rearing, and aquaculture, as ingredients for the formulation of feed supplements as well as to prevent the effects of pollution on animal productions.

Climate change is becoming a major issue for agriculture and the well-being of farmers. The objective of this article is to identify and analyze the production factors that may influence the competitiveness level of agricultural operations, as well as to establish a structural and functional typology of these farms. Using Principal component analysis (PCA) combined with hierarchical ascending classification (HAC) on 250 farmers, the study was able to set farms typology. Furthermore, variance analysis and econometric models (linear et quadratic) were also used for in-depth analysis. The results show the existence of three groups of farm (GA, GB, GC): GA (19.7%), GB (65.3%), and GC (15%). Drought spells and flood are the main climatic risks affecting rain-fed farm operations. For irrigated crops such as rice, the major constraints remain bird attacks, the invasion of pests and nematodes. Climate variability significantly increases the prevalence of morbidities in the region by raising the number of inactive individuals. This significantly and differentially affects the outcomes of these assets. Health expenditures represent a significant share (GB: 12% and GC: 11%) and a non-negligible share (GA: 8.4%). However, larger participations (GC) show better economic performance due to economies of scale, but all categories would benefit from adopting appropriate strategies to reduce losses and increase their resilience.

The fundamental scientific and engineering knowledge concerning the solar power curve, which maps solar irradiance and other auxiliary meteorological variables to photovoltaic output power, has been gathered and put forward in the preceding tutorial review. Despite the many pages of that review, it was incomplete in the sense that it did not elaborate on the applications of this very important tool of solar energy meteorology. Indeed, solar power curves are ubiquitously needed in a broad spectrum of solar forecasting and solar resource assessment tasks. Hence, this tutorial review should continue from where it left off and present examples concerning the usage of solar power curves. In a nutshell, this tutorial review,together with the preceding one, should elucidate how surface shortwave radiation data, be they ground-based, satelliteretrieved, or model-output, are bridged to various power system operations via solar power curves.

Background: The Teaching Personal and Social Responsibility (TPSR) model in physical education (PE) has been shown to promote Social and emotional competence (SEC). However, the underlying mechanisms through which TPSR enhances SEC, particularly in university students within the Chinese context, remain unclear. This study aims to explore the effects of TPSR and the mediating roles of self-efficacy and grit in improving SEC. Methods: 71 Chinese university students were in the TPSR group, and 39 in the Traditional Teaching Model (TTM) control group, assessed before and after a 14-week intervention. The Adapted Social and Emotional Competence Scale (ASECS), General Self-Efficacy Scale (GSES), and Short Grit Scale (SGS) were used for measurement. A mixed-design ANOVA assessed TPSR’s effects, with post-hoc t -tests for pre-post differences and mediation analysis for underlying mechanisms. Results: The mixed-design ANOVA revealed a significant interaction between time and intervention on SEC. The TPSR group showed significant improvement from pre-test to post-test ( t (70) = −2.63, p = 0.011, Cohen’s d = −0.31), whereas the TTM control group did not ( t (38) = 1.40, p = 0.170, Cohen’s d = 0.22). The TPSR group also showed a significant increase in self-efficacy ( t (70) = −3.67, p < 0.001, Cohen’s d = −0.44), while no change was observed in the TTM group ( t (38) = 0.62, p = 0.540, Cohen’s d = 0.10). No significant effects were found for grit ( F = 0.342, p = 0.560). Mediation analysis confirmed that self-efficacy significantly mediated the effects of the TPSR intervention on SEC (95% CI: 0.0277 to 0.2897). Conclusion: The TPSR intervention led to significant improvements in university students’ SEC and self-efficacy, with no significant changes observed in grit. Self-efficacy served as a mediator in the relationship between the intervention and SEC.
