    这项研究考察了经济增长的影响,贸易动态,自然资源,人力资本,从1990年到2022年的可持续发展。为了抓住这些因素的复杂性,我们利用了一种新的动态半参数加性面板模型。此外,我们采用动态面板阈值模型来探索自然资源对各种指标的经济发展的敏感性,解决了以往非线性技术研究中的差距。我们的发现与传统的金融发展和经济增长理论不同。虽然增加货币可能会促进贸易和发展,会阻碍可持续发展。有趣的是,金融市场扩张之间的关系,经济改善,自然资源的使用遵循反“U形”非线性模式。此外,金融部门的扩张极大地影响了人力资本和自然资源之间的相互作用。随着金融市场增长门槛的上升,经济增长更有助于可持续发展,减轻其负面影响。出现了几个含义,特别是通过全球经济和发展战略最大限度地减少能源匮乏。
    This study examines the impact of economic growth, trade dynamics, natural resources, human capital, and sustainable development from 1990 to 2022. To capture the complexity of these factors, we utilize a Novel Dynamic Semi-parametric Additive Panel model. Additionally, we employ a Dynamic panel thresholds model to explore the sensitivity of natural resources to economic development across various indices, addressing a gap in previous nonlinear technique studies. Our findings diverge from conventional financial development and economic growth theories. While increasing money may boost trade and development, it could hinder sustainable development. Interestingly, the relationship between financial market expansion, economic improvement, and natural resource use follows an inverse \"U-shaped\" non-linear pattern. Furthermore, the expansion of the financial sector significantly affects the interplay between human capital and natural resources. As thresholds of growth in financial markets rise, economic growth contributes more to sustainable development, mitigating its negative impact. Several implications emerge, particularly regarding minimizing energy deprivation through global economic and developmental strategies.

    本研究探讨了自然资源租金,工业附加值,银行业发展,可再生能源消费,1995年至2019年金砖国家动态背景下的总储量和环境质量。金砖国家经济体应对全球温室气体排放负责,并面临紧迫的环境挑战。包括生物多样性的丧失和污染。对于因变量,环境质量,该研究使用PCA为所有环境指标构建了一个综合指数,其中变量之间的相互依赖性普遍存在。除此之外,该研究结合了两个相互作用的术语,以确定自然资源租金和银行业发展通过工业增值的中介作用对环境质量的间接影响。通过应用CS-ARDL技术,研究结果表明,自然资源租金,工业附加值,总储备对ENQ有积极影响,表明工业部门对环境质量的不利影响以及由于资源密集型工业生产而导致的持续环境退化,强调可持续资源管理的紧迫性。相比之下,银行业发展和可再生能源消费对ENQ产生负面影响,标志着发达银行业在支持生态友好型项目和提高环境质量方面的积极作用。这项研究为政策干预提供了宝贵的见解,以促进更可持续的未来。
    This study explores the association between natural resources rent, industrial value addition, banking development, renewable energy consumption, total reserves and environmental quality in the dynamic context of BRICS nations from 1995 to 2019. BRICS economies are responsible for global greenhouse gas emissions and confront pressing environmental challenges, including biodiversity loss and pollution. For the dependent variable, the environmental quality, the study constructed a composite index using PCA for all environmental indicators where interdependencies among variables are prevalent. Besides this, the study incorporates two interaction terms to determine the indirect influence of natural resource rent and banking development on environmental quality through the mediating role of industrial value addition. By applying the CS-ARDL technique, the outcomes of the study reveal that natural resources rent, industrial value addition, and total reserves positively influence ENQ, indicating the adverse consequences of industrial sectors on environmental quality and continued environmental degradation due to resource-intensive industrial production, underscoring the urgency of sustainable resource management. In contrast, banking development and renewable energy consumption negatively influence ENQ, signifying the positive role of developed banking sectors in supporting eco-friendly projects and enhancing environmental quality. This study offers valuable insights for policy interventions to foster a more sustainable future.

    自然资源对发展中国家的经济和政治格局具有重大影响,这决定了环境的可持续性。这项研究探讨了治理与自然资源之间错综复杂的联系,研究资源丰度可能如何影响治理质量。理论框架考虑的这一动态的主要组成部分是Rentier效应,镇压效果,以及现代化的阻碍。本研究基于几个治理特征,应用主成分分析(PCA)创建了一个治理指数,比如政治稳定,法治,政府效能,规范和控制腐败,全面衡量治理。自然资源出口,rents,可再生和不可再生自然资源之间的区别是用于量化自然资源的三个代理,提供更细致的观点。计算可再生和不可再生自然资源对发展中国家治理的影响,计量经济学方法使用动态面板模型和系统GMM。这一分析表明,可再生资源促进包容性发展的能力对治理具有有利影响。另一方面,不可再生资源呈现负相关,主要是因为他们容易受到世界价格波动的影响,以及他们巩固权力和促进腐败的倾向。本研究强调了区分自然资源类型的重要性,以及可再生资源用于治理的可能优势和过度依赖不可再生资源的劣势。政策制定者,研究人员,对资源丰富的发展中国家遇到的发展和治理困难感兴趣的从业者可以从这项研究对自然资源与治理之间联系的更大,更复杂的理解中受益匪浅。
    Natural resources have a significant impact on economic and political landscapes of developing countries which determines environmental sustainability. This study explores the convoluted connection between governance and natural resources, examining how resource abundance might influence governance quality. The main components of this dynamic that the theoretical framework considers are the Rentier effects, the repression effects, and the obstruction of modernization. This study creates a governance index applying principal component analysis (PCA) on several governance characteristics, such as political stability, rule of law, government efficacy, regulation and control of corruption, to measure governance comprehensively. Natural resource exports, rents, and the differentiation between renewable and non-renewable natural resources are the three proxies used to quantify natural resources, providing a more nuanced view. To calculate the effect of renewable and non-renewable natural resources on governance in developing nations, the econometric methodology uses a dynamic panel model and system GMM. This analysis reveals that the ability of renewable resources to promote inclusive development has a favourable impact on governance. On the other hand, non-renewable resources show a negative correlation, mainly because of their vulnerability to swings in the world price and their propensity to consolidate power and promote corruption. The significance of differentiating between natural resource types is highlighted in this study, along with the possible advantages of renewable resources for governance and the disadvantages of an over-reliance on non-renewable resources. Policymakers, researchers, and practitioners interested in the development and governance difficulties encountered by resource-rich developing nations can benefit greatly from this research\'s larger and more complex understanding of the link between natural resources and governance.

    每年都有大量人因结核病(TB)而丧生,这是一种由结核分枝杆菌引起的古老疾病。结核病的全球传播是所有地区关注的问题。东南亚地区记录了2021年所有新发结核病例的46%,其次是非洲和西太平洋地区,分别为23%和18%。分别。研究人员一直在寻找天然物质的潜在替代疗法,以解决耐多药(MDR)结核病的令人担忧的增长,这是由于与开发新的治疗方法相关的高成本和目前使用的合成药物的不利副作用。植物化学品由于其对病原体细胞的多靶向能力而显示出作为未来健康援助的有希望的结果。在寻找新药线索时,阿育吠陀和西达医疗系统广泛使用了民族医学工具,包括使用Amalaki(EmblicaofficinalisGaertn。),古杜奇(Tinosporacordifoliawilld。),Sariva(HemidesmusindicusR.Br.),库萨(索苏雷亚·拉帕·法尔克。),姜黄(姜黄。)和绿茶(山茶。).这些来源富含类黄酮,多酚,单宁和儿茶素,已被证明可以降低结核病的风险。在本概述中,我们看看像植物这样的自然来源,藻类和蘑菇帮助研究人员找到了新的药物线索,以及如何通过绘制分子方法和其他方法来支持这些天然来源,帮助他们击败了MDR。
    A large number of people annually lose their lives to tuberculosis (TB), which is an age-old disease caused by the Mycobacterium tuberculosis. The global spread of TB is a concern for all regions. The south-east Asian region recorded 46% of all new TB cases in 2021, followed by the African and western Pacific regions with 23% and 18%, respectively. Researchers are always searching at natural substances for potential alternative therapeutics to tackle the worrisome growth in multi-drug-resistant (MDR) tuberculosis due to the high costs associated with developing new treatments and unfavourable side effects of currently used synthetic pharmaceuticals. Phytochemicals show promising results as a future health aid due to their multi-targeting ability on pathogen cells. In the search for new drug leads, the Ayurvedic and Siddha medical systems have made an extensive use of ethnomedicinal tools, including the use of plants like Amalaki (Emblica officinalis Gaertn.), Guduchi (Tinospora cordifolia willd.), Sariva (Hemidesmus indicus R.Br.), Kustha (Saussurea lappa Falc.), turmeric (Curcuma longa Mal.) and Green tea (Camellia sinensis Linn.). These sources are high in flavonoids, polyphenols, tannins and catechins, has been shown to reduce the risk of TB. In this overview, we look at how natural sources like plants, algae and mushrooms have helped researchers to find new drug leads, and how to back these natural sources through mapping the molecular approaches and other approaches has helped them to defeat MDR.

    行星健康影响心理健康和更好的气候管理,生物多样性和污染具有改善心理健康结果的共同利益。对心理健康的认识和治疗,然而,在环境和气候变化科学中被边缘化,需要对复杂的潜在过程和社会成本有更多的了解,以适当地管理和激励政策应对措施。本文提供了七项建议,强调公共政策制定者和实施者需要意识到不作为的综合成本-这可能是由于忽视心理健康和环境科学而产生的-这两个领域在历史上被边缘化了。需要改进对自然和心理健康关系进行研究的方法。通过采用心理和行为科学方法,可以加强适应和减轻气候变化和环境破坏的轨迹和模型。
    Planetary health influences mental health and a better management of climate, biodiversity and pollution has co-benefits of improving mental health outcomes. The recognition and treatment of mental health, however, has been marginalized within environmental and climate change sciences and a greater understanding of the complex underlying processes and societal costs is required to appropriately manage and motivate policy responses. The paper provides seven recommendations underscoring that public policy developers and implementors need to be aware of the combined costs of inaction - that might accrue from neglecting mental health and environmental sciences- two areas that have been historically marginalized. Improved methodologies in conducting studies on the nature and mental health nexus are needed. The trajectories and models of adaptation and mitigation of climate change and environmental damage can be strengthened through adoption of mental and behavioral sciences approach.

    基于性别的暴力(GBV)在建筑和自然资源行业引起了重大关注,在那里,女人,由于较低的社会地位和融合,风险更高。本系统综述旨在确定建筑和自然资源行业中GBV的患病率和经验。跨数据库的系统搜索,包括PubMed,OVID,Scopus,WebofScience,进行了CINAHL。麦克马斯特大学对态度和实践进行横断面调查的偏见工具的风险和牛津大学循证医学中心对定性研究的批判性评估用于评估综述中的研究。经过全文分析,共纳入六篇文章。施工中报告了GBV,采矿,城市林业,和树木栽培部门。在研究中,工作场所GBV的测量方式不同,所有研究都检查了一种以上的GBV。这些研究中讨论的GBV的主要形式是歧视,性骚扰,和性别歧视。这些研究为可能与GBV相关或不相关的人口统计学因素提供了一些见解,比如年龄,工作区域,以及在该行业工作的年限。审查还表明,工作场所的GBV对心理健康和福祉结果有负面影响,比如更高的压力和更低的工作满意度。目前的研究还没有确定干预措施的有效性,工具,或这些工作场所的政策。因此,其他研究应包括旨在减少或预防男性主导工作场所GBV的干预性研究.当前的研究可以在工作场所提高对GBV的认识和认可,并强调解决这一问题的重要性,因为本综述概述了GBV对这些男性主导行业的心理健康和福祉的负面影响。
    Gender-based violence (GBV) poses a significant concern in the construction and natural resources industries, where women, due to lower social status and integration, are at heightened risk. This systematic review aimed to identify the prevalence and experience of GBV in the construction and natural resources industries. A systematic search across databases including PubMed, OVID, Scopus, Web of Science, and CINAHL was conducted. The Risk of Bias Instrument for Cross-sectional Surveys of Attitudes and Practices by McMaster University and the Critical Appraisal of Qualitative Studies by the Center for Evidence Based Medicine at the University of Oxford were used to assess the studies included in the review. Six articles were included after full-text analysis. GBV was reported in the construction, mining, urban forestry, and arboriculture sectors. Workplace GBV was measured differently across the studies, and all studies examined more than one form of GBV. The main forms of GBV discussed in these studies were discrimination, sexual harassment, and sexism. The studies provided some insight for demographic factors that may or may not be associated with GBV, such as age, region of work, and number of years working in the industry. The review also suggests that workplace GBV has a negative impact on mental health and well-being outcomes, such as higher levels of stress and lower job satisfaction. The current research has not established the effectiveness of interventions, tools, or policies in these workplaces. Thus, additional research should include intervention studies that aim to minimize or prevent GBV in male-dominated workplaces. The current study can bring awareness and acknowledgement towards GBV in the workplace and highlight the importance of addressing it as this review outlines the negative consequences of GBV on mental health and well-being in these male-dominated industries.

    Diabetes is a substantial public health issue, while its prevalence continues to rise worldwide, affecting millions of persons between the ages of 20 and 80, the development of new therapeutic classes improving glycemic control and consequently micro and macrovascular complications are needed. Today, diabetes treatment is daily for life, and should not be interrupted. However, insulin secretagogues medications, and exogenous self-administration of insulin provide efficient antidiabetic effects, but their misuse leads to hypoglycemic complications besides other risks, hence the need to look for other natural products not to use solely but in concert with others types of medications. In this review, we will highlight briefly the pathophysiology of diabetes and its complications, then we will report the main bioactive macromolecules derived from various sources of natural products providing anti-diabetic properties. However, further researches need to be carried out to face the limitations hampering the development of effective natural drugs for diabetes treatment.

    在关于能源和环境经济学的文献中,人们普遍认为可再生能源可以改善环境质量;然而,某些论文表明,可再生能源的最佳使用水平可能存在。因此,可再生能源的利用可能导致环境退化达到一定的阈值。然后,可再生能源的持续应用可以提高环境质量。这表明可再生能源和环境破坏之间的联系是倒U型的。本文提供了有关蒂尔基耶可再生能源与环境破坏之间可能存在关联的经验证据,化石能源在能源结构中占主导地位的国家。此外,本文研究了自然资源租金和学校教育对环境的影响。这项研究利用了1971年至2020年的年度数据,并实施了依赖于傅立叶近似的时间序列方法。因此,本文考虑了不确定数量的结构断裂。结果表明,可再生能源和环境破坏之间存在倒U形联系,表示可再生能源最初有助于减少环境质量,然后再改善环境质量。此外,环境质量与自然资源租金呈正相关,与学校教育呈负相关,根据调查结果。此外,研究结果表明,学校教育恶化了可再生能源对环境退化的综合影响。本文对这些结论进行了讨论。
    Within the literature on energy and environmental economics, it is generally acknowledged that renewable energy can improve environmental quality; however, certain papers suggest that an optimal level of the usage of renewable energy sources may exist. Consequently, the utilization of renewable energy sources can result in environmental degradation up to a certain threshold. Then, environmental quality can be enhanced through the continued application of renewables. This indicates that the link between renewable energy and environmental devastation is inverted U-shaped. This paper presents empirical evidence concerning this possible association between renewable energy and environmental destruction in Türkiye, a country where fossil energy predominates in the energy mix. Additionally, the paper investigates the environmental influences of natural resource rents and schooling. This study utilizes annual data from 1971 to 2020 and implements time series methodologies that rely on the Fourier approximation. The paper thus accounts for an undetermined quantity of structural breaks. The results suggest that an inverted U-shaped link occurs between renewable energy and environmental destruction, signifying renewable energy initially contributes to a diminution in environmental quality before subsequently improving it. Additionally, environmental quality is positively associated with natural resource rents and negatively associated with schooling, according to the findings. Furthermore, the findings reveal that schooling worsens the combined effect of renewable energy on environmental degradation. These conclusions are discussed in the paper.

    这项研究探讨了2011年至2021年间,数字经济(DE)对中国275个城市的自然资源效率(NRE)的影响。通过全面的实证分析,我们发现DE显著正向影响NRE。这种关系中的一个关键调节因素是绿色技术创新(GTI),注重绿色技术的质量而不是数量。我们的研究还发现了调节作用的区域差异。此外,我们确定了DE有助于增强NRE的几种机制,包括产业结构的转变和绿色全要素生产率的提高。详细的异质性分析表明,DE\对NRE的影响根据城市特定因素如自然资源禀赋而有所不同,城市大小,环境法规,和行政级别。这些发现对DE如何影响城市层面的NRE提供了更细致的理解,为数字时代可持续发展的更广泛讨论做出贡献。我们的研究为城市利用DE提高自然资源效率提供了政策建议和潜在途径。
    This study explores the impact of the digital economy (DE) on natural resource efficiency (NRE) across 275 Chinese cities between 2011 and 2021. Through a comprehensive empirical analysis, we find that the DE significantly positively affects NRE. A key moderating factor in this relationship is green technological innovation (GTI), focusing on the quality rather than the quantity of green technology. Our study also uncovers regional variations of moderating effect. Additionally, we identify several mechanisms through which the DE contributes to enhanced NRE, including the transformation of industrial structure and improvements in green total factor productivity. A detailed heterogeneity analysis shows that the DE\'s impact on NRE varies according to city-specific factors such as natural resource endowment, city size, environmental regulations, and administrative levels. These findings provide a more nuanced understanding of how the DE influences NRE at the urban level, contributing to the broader discourse on sustainable development in the digital age. Our research offers policy recommendations and potential pathways for cities to leverage the DE for greater natural resource efficiency.
