Although the impact of integrating solar and wind sources into the power system has been studied in the past, the chaos caused by wind and solar energy generation has not yet had broader mitigation solutions notwithstanding their rapid deployment. Many research efforts in using prediction models have developed real-time monitoring of variability and machine learning predictive algorithms in contrast to the conventional methods of studying variability. This study focused on the causes and types of variability, challenges, and mitigation strategies used to minimize variability in grids worldwide. A summary of the top ten cases of countries that have successfully managed variability in their electrical power grids has been presented. Review shows that most of the success cases embraced advanced energy storage, grid upgrading, and flexible energy mix as key technological and economic strategies. A seven-point conceptual framework involving all energy stakeholders for managing variability in power system networks and increasing variable renewable energy (VRE)-grid integration has been proposed. Long-duration energy storage, virtual power plants (VPPs), smart grid infrastructure, cross-border interconnection, power-to-X, and grid flexibility are the key takeaways in achieving a reliable, resilient, and stable grid. This review provides a useful summary of up-to-date research information for researchers and industries investing in a renewable energy-intensive grid.

Strategic IPO Timing of Technology Innovation-Driven Enterprises: A Differential Game Analysis of Market Returns, Disclosure Costs, and Industry Dynamics

This article develops a dual-oligopoly differential game model to analyze how technological impacts influence product market competition. This model undertakes a systematic examination of the strategic balancing act enterprises engage in when confronted with technological innovation opportunities, weighing market returns against information disclosure costs in the context of IPO decision-making. The findings reveal that the temporal dimension of technological catch-up and the firms’ intrinsic innovation capabilities are pivotal determinants of IPO timing. Specifically, enterprises that have achieved rapid technological parity and possess robust innovative capacities are more prone to expedite IPOs, seeking to secure funding for further technological advancements and market expansion endeavors. Conversely, elevated information disclosure costs may incentivize companies to postpone IPOs, aiming to shield their technological assets and market strategies from premature competitor scrutiny. Additionally, the study highlights the paradoxical influence of intense market competition: while it incentivizes early IPOs to bolster resource acquisition for competitive strategies, it also exacerbates the detrimental effects of disclosure costs on IPO timing. In conclusion, this investigation not only contributes to the theoretical corpus on IPO decision-making but also offers pragmatic guidance for corporate executives in crafting IPO strategies and serves as a valuable reference for fostering the sustainable development of capital markets.

A systematic literature review of security and privacy by design principles, norms, and strategies for digital technologies

ABSTRACT This paper offers a comparative systematic literature review of the key principles, norms, and strategies associated with Security by Design (SbD) and Privacy by Design (PbD). Both frameworks are grounded in the idea that security and privacy should be integral components of digital technologies from the very beginning of the design process. Following PRISMA guidelines, we reviewed 82 documents sourced from databases such as the ACM Digital Library, EBSCO Library, IEEE Xplore, ProQuest, Scopus, and Web of Science. Our analysis reveals that SbD and PbD share four fundamental principles: prevention/proactiveness, embeddedness, user-centricity, and transparency. The review also highlights the solid regulatory foundation of PbD, particularly under the General Data Protection Regulation (GDPR), compared to the emerging regulatory context for SbD. Additionally, we explore a range of strategies, from organizational cultural changes to technical interventions, that illustrate the nuanced approaches taken to implement these paradigms. We conclude by discussing the broader implications of these findings and suggesting directions for future research, aiming to contribute to the development of technologies that are both secure and respectful of privacy, while also advocating for integrated frameworks that enhance digital trust.

වනජිවීන් හා මිනිසුන් අතර ඇතිවන ගැටුම් වළක්වා ගැනීමට සාම්ප්‍රදායිකව යොදාගත් කෙම් ක්‍රම පිළිබඳ මානව විද්‍යාත්මක අධ්‍යයනයක්

Since the beginning of human history, humans have been a part of the environment, interacting with plants and animals. Over time, this loss of connection has led to various conflicts between humans and animals. Various methods have been developed as part of human culture to prevent these conflicts. Among the traditional methods, techniques such as mechanical methods, medicinal control methods, biological control methods, Kem methods, etc. can be identified. Among these methods, Kem methods are unique in that cultural values have been embedded in those Kem methods. The lack of this traditional knowledge among the current people, the fact that new technological methods are only friendly to humans, and the fact that these methods are not sufficient, has led to the current conflict between wildlife and humans. This research aims to explore the methods built on traditional knowledge based on this problem. The two Grama Niladhari Divisions of Mariarawa and Okkampitiya in the Monaragala District were used as the study areas. Ten elders above the age of fifty were selected as the research sample through purposive sampling method and relevant data were collected using observation and structured interviews. The study rediscovered many traditional methods. These include the beliefs of the villagers, Manthra (spells), traps, the use of medicines, biological control methods and a variety of Kem methods. Among these, Kem methods are also used for other strategies such as various mechanical methods. Many of the traditional methods, including Kem methods, identified from the field of study and literary sources, were successful and had a scientific basis. It was concluded that traditional methods contain technological strategies that offer better and more effective solutions than modern techniques. Also, the researcher suggests that efforts to prevent and address the current acute human-wildlife conflicts in Sri Lanka by combining traditional knowledge with modern technology would be more effective. It is a good alternative to solve problems by filling the gaps in modern techniques.

The introduction of interactive mobile technology has made the teaching process more flexible and diverse, providing new forms and approaches for teacher-student interaction. However, how to scientifically assess and effectively optimize teacher-student interaction remains a critical issue in current educational research. Existing studies mainly focus on technological applications and lack an in-depth exploration of the essence of interaction, particularly in terms of the quantitative analysis of interaction intensity and evolution. This study aims to explore the application and optimization strategies of interactive mobile technology in teacher-student interactive language teaching. The study includes four main components: first, analyzing the evolution of teacher-student interaction in language teaching; second, calculating the intensity of teacher-student interaction based on information entropy; third, constructing and calculating a model for the evolution of interaction intensity; and fourth, proposing language teaching optimization strategies based on the evolution of teacher-student interaction intensity. This study, through theoretical modeling and empirical analysis, seeks to provide scientific evidence and practical guidance for improving the quality of teacher-student interaction and optimizing language teaching.

The adoption strategy of blockchain technology for new and remanufactured products considering price and consumer preference

ABSTRACT The remanufacturing industry has become an important part of the circular economy and green manufacturing industry. However, information asymmetry and consumer preference are major obstacles to the development of remanufacturing. The emergence of blockchain technology(BCT) can alleviate these problems. Based on the idea, the strategic choice of new products(NPs) and remanufactured products(RPs) under the internal competition of the manufacturer is examined, and the influence of price competition, consumers’ low-carbon preference and the cost on the strategic choice is analyzed. Then we determine the conditions for this manufacturer to adopt BCT. The results show that adopting BCT is conducive to creating a green brand image for RPs and attracting environmentally conscious consumers. Cost is an important factor that affects decision-making. In addition, consumers may be more concerned about the manufacturer mixing counterfeit ingredients into NPs, which seriously affects consumers’ trust in the quality of NPs and the following manufacturer’s adoption strategy.

Research on the Carbon Footprint Accounting Method of Transformer’s Whole Life Cycle Under the Background of Double Carbon

In response to the existing gaps in the carbon footprint assessment framework for core electrical equipment transformers, which impedes power companies from effectively supporting low-carbon procurement of materials and products, this study proposes a novel evaluation method for transformer carbon footprints. This method comprehensively considers all stages of the transformer lifecycle, including manufacturing, transportation, installation, operation, and decommissioning. A review of mainstream carbon footprint accounting schemes, both domestic and international, is first presented, summarizing established accounting methods and calculation processes. The paper then introduces a novel, integrated carbon footprint accounting approach for transformers, covering the entire ‘cradle-to-grave’ lifecycle, along with an associated calculation model. This framework analyzes the carbon footprint composition across production, assembly, transportation, usage, and recycling stages for four commonly used, high-efficiency transformers at State Grid Xinjiang Electric Power Company, the carbon footprint of an oil-immersed 100 kVA/10 kV transformer is 2.353 × 106 kg CO2e, approximately half that of a conventional 100 kVA/10 kV transformer. Finally, the study provides recommendations for carbon reduction pathways for transformers, considering both functional substitution and technological carbon reduction strategies.

A systematic literature review on adaptation strategies towards climate change impacts among Indigenous fishers

ABSTRACT Indigenous fishers are known for their traditional fishing methods and high reliance on ecosystem stability. Climate change poses a formidable challenge to their way of life. Climate change adaptation refers to an adjustment in ecological, social, or economic systems in response to actual or expected climatic stimuli. Studies are being conducted worldwide on how Indigenous peoples are responding to climate change impacts. The main aim of this study was to develop a systematic literature review (SLR) on how Indigenous fishers adapt to these impacts. RepOrting Standards for Systematic Evidence Syntheses (ROSES) were used to guide the present SLR and formulate research questions based on the mnemonic “population, interest, and context” (PICo). From a search in 4 primary databases, 115 potential articles were found and 21 were analyzed. Four studies were conducted in the United States, and others were conducted in Asian, Northern American, and African regions. Five main themes were elaborated: Indigenous knowledge of weather prediction; Indigenous practices; livelihood diversification; technology and infrastructure-based adaptation strategies; and collective action and collaboration. Senior fishers actively used Indigenous knowledge and practices, but the younger generation preferred to use technology (e.g., GPS, satellite data, snowmobiles) in their fishing operations. To sustain their livelihood, some Indigenous fishers rely on alternative jobs (non-fisheries related), use multiple fishing techniques, or catch marine species. The review suggests the need to integrate Indigenous opinions, experiences, and knowledge into climate change-related policy, active involvement of Indigenous fishers in habitat restoration, use of technology, and diversification of livelihood, to combat climate change impacts among Indigenous fishers.
