The strategic analysis for the decommissioning of thermoelectric plants is seen as a trend for the coming years. The search for renewable alternatives should stimulate investment in other energy sources, reducing the number of thermoelectric plants in the energy generation system. However, few studies have dealt with the decommissioning of oil-fired thermoelectric plants. In this work, the methodology was applied under deterministic and stochastic conditions using methods of net present value (NPV), internal rate of return (IRR), discounted payback, capital asset pricing model (CAPM) and weighted average cost of capital (WACC). The results showed that the deterministic NPV was positive, ranging from R$101.30 million (pessimistic scenario) to R$109.73 million (optimistic scenario). The IRR was higher than the WACC of 10.55 %, ranging from 13.50 % to 13.68 % per year. For the Monte Carlo simulation, NPV was observed with 100 % certainty of viability and the probabilities of occurrence allowed more analysis of the risks involved than those obtained by deterministic methods. this study contributes to future decommissioning projects in Brazil, considering the scenario of stimulating renewable sources and the energy transition, helping managers make decisions about their projects. In addition, it helps guide public policies that can optimize the decommissioning process and strengthen the national energy sector.
热电厂退役的战略分析被视为未来几年的趋势。对可再生替代能源的探索将刺激对其他能源的投资,从而减少能源生产系统中热电厂的数量。然而,很少有研究涉及燃油热电厂的退役问题。在这项工作中,采用净现值 (NPV)、内部收益率 (IRR)、贴现投资回收期、资本资产定价模型 (CAPM) 和加权平均资本成本 (WACC) 等方法,在确定性和随机条件下应用了该方法。结果表明,确定性净现值为正值,从 1.013 亿雷亚尔(悲观方案)到 1.0973 亿雷亚尔(乐观方案)不等。内部收益率高于 10.55%的加权平均资本成本,从每年 13.50%到 13.68%不等。在蒙特卡洛模拟中,净现值(NPV)的确定性为 100%,与确定性方法相比,发生概率允许对所涉及的风险进行更多分析。这项研究有助于巴西未来的退役项目,考虑到刺激可再生能源和能源转型的情况,帮助管理人员对其项目做出决策。此外,它还有助于指导公共政策,优化退役过程并加强国家能源部门。

In the face of worsening global environmental degradation, significant attention has been devoted to the greening of industrial transformation and development, specifically by improving industrial green total factor productivity (GTFP). We explored the impact of environmental regulations on industrial GTFP and the moderating influence of R&D subsidies. We established a theoretical model in which environmental regulations affect industrial GTFP, and this relationship is moderated by R&D subsidies. The results revealed that the impact of environmental regulations on industrial GTFP is U-shaped and that the current level of environmental regulation is insufficient to boost industrial GTFP. Green technological innovation plays a mediating role in the effect of environmental regulations on industrial GTFP. Furthermore, R&D subsidies nonlinearly moderate the relationship, resulting in a steeper U-shaped curve and accelerating the arrival of the tipping point. These findings provide theoretical support and a reference for government policies that promote industrial greening.
面对日益恶化的全球环境恶化问题,人们开始关注工业转型和发展的绿色化,特别是通过提高工业绿色全要素生产率(GTFP)来实现。我们探讨了环境法规对工业全要素生产率的影响以及研发补贴的调节作用。我们建立了一个理论模型,在该模型中,环境法规影响工业全要素生产率,而这种关系受到研发补贴的调节。结果表明,环境规制对工业 GTFP 的影响呈 U 型,当前的环境规制水平不足以促进工业 GTFP 的增长。绿色技术创新在环境规制对工业 GTFP 的影响中起中介作用。此外,研发补贴非线性地缓和了这一关系,导致 U 型曲线更加陡峭,加速了临界点的到来。这些发现为政府促进工业绿色化的政策提供了理论支持和参考。

Human Development and its regional disparity is an area of topical interest. In this paper, we consider space as an instrumental variable in understanding this disparity and explore spatial interdependence in human development across districts of West Bengal using alternate indicators of human development. This study uses both the standard United Nations Development Programme (UNDP) technique and an alternative methodology to construct a sub-national human development index. Spatial interdependence is measured using Moran's I coefficient and Local Indicators of Spatial Autocorrelation (LISA) cluster maps. Spatial regression is used to evaluate the spatial association between the Human Development Index as the dependent variable and a few independent variables. A high degree of clustering in all three dimensions of human development is observed among the southern districts of West Bengal. The pattern of cluster maps indicates the presence of both the growth pole process and the metropole-periphery process in the state. Spatial regression results indicate that the share of socially backward class population and urbanization rate are important variables affecting regional human development patterns. The findings of this study suggest policies targeted to promote social inclusion and urbanization linked with better access to economic opportunities in the lagging areas can help reduce regional imbalances.
人类发展及其地区差异是一个备受关注的领域。在本文中,我们将空间视为理解这种差异的工具变量,并利用人类发展的替代指标探讨西孟加拉邦各地区人类发展的空间相互依存性。本研究同时使用联合国开发计划署(UNDP)的标准技术和替代方法来构建次国家人类发展指数。使用莫兰 I 系数和地方空间自相关指标(LISA)聚类图来衡量空间相互依存性。空间回归用于评估因变量人类发展指数与几个自变量之间的空间关联。在人类发展的所有三个维度中,西孟加拉邦南部各县的聚类程度都很高。聚类图的模式表明,该邦存在增长极进程和都会-外围进程。空间回归结果表明,社会落后阶层人口比例和城市化率是影响地区人类发展模式的重要变量。这项研究的结果表明,有针对性地促进社会包容和城市化的政策与落后地区更好地获得经济机会相联系,有助于减少地区失衡。

Transparency and accountability are critical components of corporate sustainability. This study uses machine learning and empirical analysis to examine the influence of corporate social responsibility (CSR) committees and environmental, social, and governance (ESG) initiatives on corporate sustainability. Using 2017–2021 Bloomberg Terminal data, we investigated the environmental footprints, disclosure practices, risk profiles, and ESG fund commitments of Fortune 500 companies. Key findings indicate that CSR committees positively impact environmental performance, with an increase in environmental responsibility over time. Policy implications highlight the necessity for collaboration to prioritize environmental sustainability and address climate risk disclosure auditing within the audit profession.

The surge in informal E-waste recycling has led to significant resource wastage and environmental hazards. The current government-centered governance system faces substantial obstacles to effective implementation due to information gaps and operational challenges. This study adopts the concept of social governance by incorporating public participation into the traditional government-led e-waste recycling system. Utilizing the bounded rationality of evolutionary game theory, this research constructs a tripartite game model involving the government, recyclers, and the public. It analyzes the behavioral strategy choices of each participant and the mechanisms of mutual influence under different scenarios. The main findings are: (1) Solely relying on public power is insufficient for effectively governing informal recyclers. (2) Reasonable and moderate incentives can promote public participation, serving as an effective supplementary tool for government regulation. (3) Increasing public exposure to the informal dismantling behaviors of recyclers is crucial for enhancing governance effectiveness. Specific measures can include establishing complaint departments for related incidents and creating media channels. These findings underscore the importance of integrating public participation into e-waste governance to address the limitations of a purely government-centered approach.
非正规电子废物回收的激增导致了严重的资源浪费和环境危害。当前以政府为中心的治理体系由于信息空白和操作挑战,在有效实施方面面临巨大障碍。本研究采用社会治理的概念,将公众参与纳入传统的政府主导型电子废弃物回收体系。利用进化博弈论的有界理性,本研究构建了一个涉及政府、回收者和公众的三方博弈模型。研究分析了不同情景下各参与方的行为策略选择和相互影响机制。主要结论如下(1) 仅仅依靠公共权力不足以有效治理非正规回收商。(2) 合理适度的激励措施可以促进公众参与,成为政府监管的有效补充工具。(3) 增加公众对回收者非正规拆解行为的曝光度是提高治理效果的关键。具体措施可包括建立相关事件的投诉部门、开辟媒体渠道等。这些发现强调了将公众参与纳入电子废物治理的重要性,以解决纯粹以政府为中心的方法的局限性。

The United Nations’ Sustainable Development Goals have been gaining traction. Green entrepreneurship has emerged as an appealing strategy for governments and educators to address environmental problems. This study examines the determinants affecting the transformation of green entrepreneurial intention into behaviour, a previously unexplored area. Specifically, the moderating roles of sustainability orientation, environmental knowledge, subjective norms, and external institutional support on the effect of green entrepreneurial intention on behaviour are examined. A quantitative survey of 663 Taiwanese individuals was conducted between November and December 2022. The factor structure was evaluated using exploratory factor analyses. The positive relationship between green entrepreneurial intention and behaviour was validated using multiple regression analysis. Environmental knowledge, subjective norms, and external institutional support, but not sustainability orientation, had positive moderating roles. These findings enrich existing theories, including the theory of planned behaviour and social cognitive career theory, and provide practical guidance to educators and policy makers promoting green entrepreneurial action.
联合国的可持续发展目标越来越受到重视。绿色创业已成为政府和教育工作者解决环境问题的一项有吸引力的战略。本研究探讨了影响绿色创业意向转化为行为的决定因素,这是一个之前尚未探索过的领域。具体而言,研究了可持续发展导向、环境知识、主观规范和外部机构支持对绿色创业意向行为影响的调节作用。2022 年 11 月至 12 月期间,对 663 名台湾人进行了定量调查。采用探索性因子分析评估了因子结构。采用多元回归分析验证了绿色创业意向与行为之间的正相关关系。环境知识、主观规范和外部制度支持(而非可持续发展导向)起到了积极的调节作用。这些发现丰富了现有理论,包括计划行为理论和社会认知职业理论,并为教育工作者和政策制定者促进绿色创业行动提供了实际指导。

The disruptive innovation framework has been suggested to enhance new venture sustainability in resource-constrained contexts. This paper explores the role of human capital and strategic posture on disruptive innovation capability in low-income and resource-constrained environments. Using a generic qualitative inquiry strategy, we develop propositions tested by 20 in-depth interviews with entrepreneurs and industry role players in the South African startup incubation sector. Data from the interviews were analyzed through thematic analysis with constant comparison. The findings suggest that adopting an emerging market orientation and taking strategic risks assists in identifying the right consumer target market. Innovativeness is linked to effective product development processes, and a learning orientation contributes to the development of the skills and capabilities required for successful innovation in resource-constrained environments. Additionally, the findings emphasize prior founder knowledge and industry experience in shaping the strategic posture of entrepreneurs. Resource-constrained contexts vary significantly across regions. Our study contributes to the body of knowledge on disruptive innovations and small business sustainability in resource-constrained environments by investigating entrepreneurial dynamics in South Africa.
有人建议采用破坏性创新框架来增强新企业在资源受限环境下的可持续性。本文探讨了在低收入和资源有限的环境中,人力资本和战略态势对破坏性创新能力的作用。我们采用通用的定性调查策略,通过对南非初创企业孵化部门的企业家和行业参与者进行 20 次深入访谈,提出了经过检验的命题。我们通过主题分析和持续比较对访谈数据进行了分析。研究结果表明,以新兴市场为导向并承担战略风险有助于确定正确的目标消费市场。创新性与有效的产品开发流程有关,而学习导向则有助于在资源有限的环境中发展成功创新所需的技能和能力。此外,研究结果还强调了创始人先前的知识和行业经验对创业者战略态势的影响。不同地区的资源受限环境差异很大。我们的研究通过调查南非的创业动态,为有关资源受限环境下颠覆性创新和小企业可持续性的知识体系做出了贡献。

Virtual Reality (VR) revolutionises education, offering a uniquely immersive and engaging learning experience. It fosters personalised learning, ignites creativity, and enhances understanding through interactive 3D models. These models transport students into a virtual world, facilitating better comprehension and memory retention. VR also addresses crucial educational challenges, such as catering to students with special needs and enabling remote learning. Nevertheless, VR also faces challenges like high initial investment and, hence, has limited adoption in education. Thus, to overcome this challenge, Additive Manufacturing (AM) is identified as an emerging technology that complements VR in education. VR provides a digital model, whereas AM provides 3D physical models, enhancing understanding in students. These technologies reduce paperwork, promote a sustainable environment, and facilitate students to learn from their homes, reducing their travelling requirements. This paper highlights that using these technologies in education contributes to achieving many United Nation's Sustainable Development Goals.
This is a review-based research, where a scoping review has been presented, with articles and research papers from the relevant sources collected and analysed to address the well identified research objectives. It also compares traditional and VR-based teaching-learning, provides a broad classification for the different education segments targetable through VR, the economic impact of VR on education, and significant applications and advantages of VR in education.

Sustainable development is the key to achieving high-quality growth in the manufacturing industry. The article analyzes the impact of energy inputs and carbon emission constraints on the ESG performance of Chinese manufacturing firms using listed company data from 2011-2022, carbon market emission control firms, and new energy city policies. The study finds the following core conclusions. First, energy input-carbon emission constraints can significantly improve the overall ESG performance of manufacturing firms rather than being limited to improving one aspect of performance. The benchmark regression results remain robust after a series of robustness tests. Second, the mechanism test shows that the energy input-carbon emission constraint can improve the ESG performance of manufacturing firms by promoting public green concern in the source prevention link, corporate green technology innovation in the process control link, and corporate green investment in the end governance link. In addition, enterprises' horizontal competition and vertical cooperation factors have a moderating effect on the direct impact of energy input-carbon emission constraints. Supply chain integration as a vertical cooperation factor positively reinforces the marginal increment. Firm competitiveness as a horizontal competition factor produces a "U" shaped moderating effect that is first weak and then strong. Finally, the heterogeneity analysis finds that the energy input-carbon emission constraint effectively promotes the ESG performance of technology-intensive and mature manufacturing firms and has a "sending charcoal in the snow" effect on the ESG performance of manufacturing firms in high-carbon industries. Therefore, the two-end synergistic constraint of energy input-carbon emission can effectively promote the growth of ESG performance of manufacturing enterprises, which brings important insights to the green development of manufacturing industries in other countries.
可持续发展是制造业实现高质量增长的关键。文章利用2011-2022年上市公司数据、碳市场排放控制企业和新能源城市政策,分析了能源投入和碳排放约束对中国制造业企业ESG绩效的影响。研究得出以下核心结论。首先,能源投入-碳排放约束能够显著改善制造业企业的整体环境、社会和公司治理绩效,而不仅仅局限于改善某一方面的绩效。经过一系列稳健性检验,基准回归结果依然稳健。其次,机理检验表明,能源投入-碳排放约束可以通过促进源头预防环节的公众绿色关注、过程控制环节的企业绿色技术创新和末端治理环节的企业绿色投资来改善制造业企业的ESG绩效。此外,企业的横向竞争和纵向合作因素对能源投入-碳排放约束的直接影响具有调节作用。作为纵向合作因素的供应链整合对边际增量有正向强化作用。作为横向竞争因素的企业竞争力产生了先弱后强的 "U "型调节作用。最后,异质性分析发现,能源投入-碳排放约束有效促进了技术密集型和成熟制造业企业的ESG绩效,对高碳行业制造业企业的ESG绩效有 "雪中送炭 "的作用。因此,能源投入-碳排放的两端协同约束能够有效促进制造业企业ESG绩效的增长,为其他国家制造业的绿色发展带来重要启示。

Due to the high pollution caused by the consumption of energy from fossil fuels, governments have implemented policies that allow the transition to renewable sources, but this depends on many factors associated with the costs and attitudes of the population. This study examines the influence of perceived costs, benefits, and environmental concerns on the behavioral intentions toward renewable energy (RE) adoption in Ciudad Juarez, Mexico. A structural equation model is used to validate five hypotheses and information from 511 responses to a survey to explore how perceived costs (PCO) as an independent variable, perceived benefits (PBE), and environmental concerns (ECO) as mediators support intentions to adopt solar energy technologies. Findings reveal that PCO impacts PBE and ECO directly and influences behavioral intentions (BIN) indirectly. This underscores the importance of analyzing PCO in the context of developing countries due to the low per capita income. The study identifies ECO as the most significant factor affecting BIN and PBE as the primary influencer of ECO, suggesting that promoting the benefits of RE could enhance environmental concerns and, consequently, adoption intentions. Sensitivity analysis indicates the necessity of effectively disseminating cost-related information, as costs often overshadow perceived benefits. The findings advocate for clear communication regarding RE costs and benefits and the formulation of supportive policies to facilitate RE adoption in Mexico, highlighting the crucial role of comprehensive awareness strategies in improving public perception and acceptance of RE technologies, providing valuable insights for policymakers, stakeholders, and educators to promote sustainable energy practices.
由于化石燃料能源消耗造成的高污染,各国政府已经实施了允许向可再生能源过渡的政策,但这取决于与成本和民众态度相关的许多因素。本研究探讨了墨西哥华雷斯市的可感知成本、收益和环境问题对采用可再生能源(RE)的行为意向的影响。研究采用结构方程模型验证了五个假设,并从 511 份调查反馈中获取信息,以探讨作为自变量的感知成本 (PCO)、感知收益 (PBE) 和环境问题 (ECO) 作为中介变量如何支持采用太阳能技术的意愿。研究结果表明,PCO 直接影响 PBE 和 ECO,间接影响行为意向 (BIN)。这强调了在发展中国家分析 PCO 的重要性,因为这些国家的人均收入较低。研究发现,ECO 是影响 BIN 的最重要因素,而 PBE 则是 ECO 的主要影响因素,这表明宣传可再生能源的益处可以提高人们对环境的关注,从而提高采用意愿。敏感性分析表明,有效传播与成本相关的信息很有必要,因为成本往往会盖过所感知到的益处。研究结果提倡就可再生能源的成本和效益进行清晰的沟通,并制定支持性政策以促进可再生能源在墨西哥的应用,强调了全面的宣传战略在提高公众对可再生能源技术的认知和接受程度方面的关键作用,为政策制定者、利益相关者和教育工作者提供了宝贵的见解,以促进可持续能源实践。
