  • Publicly accountable deliberation using digital ICT: building understanding and integrity in KQA practices   Order a copy of this article
    by Jean-Marc Douguet, Philippe Lanceleur, Martin Paul O'Connor 
    Abstract: We take up the challenge of publicly accountable deliberation processes for building integrity of knowledge claims in situations of controversy. We characterise Knowledge Quality Appraisal (KQA) in a perspective of Post Normal Science (PNS), and propose the structuring of KQA as a process of deliberative multi-criteria and multi-actor evaluation, with a four-dimensional framework (What, Who, Why and How) for extended peer community dialogue. Turning to the question, to what extent can such procedures be effective, we insist that implementing a robust KQA procedure in situations of societal controversy can, both in theory and in practice, be only imperfect at best. Nonetheless, deliberative KQA methods can be motivated, on epistemological as well as moral grounds, in support of (utopian) ideals of inclusive, open, convivial, and humane societies.
    Keywords: deliberation; extended peer community; integrity; knowledge quality assessment; post normal science.

  • An evaluation method of English teaching quality based on Markov chain   Order a copy of this article
    by Lifeng Li 
    Abstract: Focusing on improving the accuracy and comprehensiveness of teaching quality evaluation results, a Markov chain-based English teaching quality evaluation method is proposed. Construct a teaching quality evaluation index system and calculate the specific weights of different evaluation indicators in the system through an analytic hierarchy process. Based on the weight calculation results, the state-transition matrix is established using the Markov chain method, and more states are introduced to construct the state-transition matrix. According to the state-transition matrix, the residual sequence with the same position is obtained under the original data sequence, and the upper and lower boundary values of different residual sequences are obtained. Combined with the steady-state distribution vector, the teaching quality evaluation results are obtained. The experimental results show that the evaluation results of the proposed method have lower errors and are more comprehensive.

  • Assessment of clean energy development path based on carbon emission data: achieving sustainable development goals   Order a copy of this article
    by Shulei Qi 
    Abstract: The development of clean energy is usually influenced by seasonal factors, and traditional manual experience assessment methods often fail to consider these seasonal factors and overlook periodic trends. Through the Holt-Winters method, carbon emission data was comprehensively and accurately evaluated to guide the achievement of sustainable development goals. The relevant carbon emission data was collected, and the Holt-Winters method combined trend, seasonal, and cyclical components to better capture and fit seasonal change patterns, providing more accurate predictions of clean energy development paths. In 2022, the electricity generated by City A using wind power was 31.6% more than that generated by City A using fossil fuels in 2021, and the carbon emissions were 57.1% lower. This data has provided important information for policy makers to help them formulate clean energy policies, regulations, and measures, helping to ensure social, economic, and environmental sustainability.

  • An interior design method based on the coupling of I-GWO and self-updating neural network under the background of green interaction   Order a copy of this article
    by Shasha Luo 
    Abstract: In the context of verdant interplay, interior design is progressively compelled to appraise the equilibrium between ecological sustainability and user experientiality. To this end, this manuscript postulates a novel interior design algorithm rooted in the interaction grey wolf algorithm (I-GWO) conjoined with a self-updating neural network. Initially, a tailored I-GWO is harnessed to fine-tune the interior design proposal, wherein the design quandary is transformed into an optimisation conundrum, thereby deploying the I-GWO to navigate the realm of optimal solutions. Subsequently, a bespoke self-updating neural network is architected, amalgamating convolutional neural networks (CNN) and long-short-term memory (LSTM), thereby refining the design blueprint even further. This contrived neural network evinces the innate capacity to autonomously assimilate and update weights and biases. The nomenclature and precepts of interior design are thereby assimilated through the synergy of the I-GWO and self-updating neural network. Finally, empirical attestations evince the algorithm’s meritorious aptitude in optimising interior design schemes while adeptly incorporating considerations of environmental sustainability. The outcomes evince a noteworthy 42.5% enhancement in temporal efficiency when compared to extant state-of-the-art algorithms. Furthermore, the proposed method attains the zenith in convergence efficacy when juxtaposed with six other state-of-the-art algorithms.

    by Shasha Zhang, Shu Liu 
    Abstract: The evaluation of agricultural economic sustainability plays a crucial role in promoting the sustainable development of agriculture. Therefore, an evaluation method of sustainable development level of agricultural economy under the economic new normal is proposed. Bartlett's sphericity test is used to determine the correlation between evaluation indicators under the new normal of the economy, and an evaluation indicator system is established. The combination weights of evaluation indicators are obtained through the expert method and entropy method. The comprehensive positive distance and comprehensive negative distance of evaluation objects are calculated using the interval scale method. This allows for the calculation of scores for each level of agricultural economic sustainability, resulting in relevant evaluation results. Experimental results show that the maximum correlation value of evaluation indicators for this method is 0.96, the maximum average relative error rate of indicator weights is 4.36%, and the accuracy ranges from 93.9% to 97.2%.

    by Mingming Deng 
    Abstract: Based on the analysis of the main pollution characteristics of urban water environment, a distributed monitoring method of urban water environment pollution condition from the perspective of sustainable development based on multi-parameter autoregressive analysis is proposed. A constraint parameter model for spatio-temporal distribution characteristics analysis is constructed, and water eutrophication and pollution contribution degree of soil nitrogen pool are taken as the optimisation model parameters. The multivariate statistical method is adopted to detect the pollution principal component characteristics, and the quantitative fusion index parameter analysis is carried out based on both principal component analysis and cluster analysis to identify the pollution control factors affecting the water environment. The distributed monitoring of urban water environmental pollution is realised based on the characteristics change and the requirements of regulation targets. The experimental results show that the method has a good ability to express statistical characteristics and monitoring accuracy reached 99.8%, it can effectively monitor various pollution components.

    by Yanhua Huang, Liying Su 
    Abstract: In order to effectively shorten the logistics delivery path and shorten the driving time, a regional logistics delivery path optimisation method based on ant colony optimisation algorithms was proposed. Considering the complexity of regional logistics delivery, the delivery area is divided based on factors such as customer location, demand, and time window information. Analyse the transportation conditions of regional logistics delivery paths, with the goal of minimising carbon emissions in the shortest possible time, and construct an optimisation function for regional logistics delivery paths. The ant colony optimisation algorithms are used to optimise the time and carbon emission parameters, solve the objective function, and finally obtain the optimal regional logistics delivery path. The experimental results show that using the proposed method can better solve the problem of regional logistics delivery path, shorten the path and driving time of logistics delivery.

  • Exploring the effect of BERT and attention mechanisms on predicting futures prices in the green finance market   Order a copy of this article
    by Yue Liang 
    Abstract: As the green finance sector develops, there is an increasing demand for forecasting future prices. To investigate the influence of futures prices on green financial markets, an innovative technique is suggested that uses BERT and attention mechanisms. The foundations of futures price prognostication are primarily strengthened by a feature amalgamation methodology using an attentional strategy. Then, to facilitate deft deduction, a BERT-grounded approach is suggested for predicting future prices within the context of the green financial market. The empirical findings demonstrate that the mean absolute percentage error (MAPE) value obtained by the proposed methodology stands impressively at 0.653, reiterating the suggested paradigm’s clear efficacy. The study lays the foundation for implementing ecological fiscal stewardship and creating sustainable market strategies.

  • Digital innovations and green finance: accelerating carbon neutrality in enterprise sustainability   Order a copy of this article
    by Li Han, Congcong Duan, Zhenfei Yao 
    Abstract: Green finance (GF) is a pivotal driver for enhancing carbon-neutrality, ultimately fostering the sustainable development of enterprises. Drawing upon provincial panel data spanning 2007 to 2017, this study examines the impact of GF on carbon-neutrality and its mechanisms. The empirical findings highlight GF’s significant positive influence on achieving carbon-neutral goals, a relationship that withstands varying research methodologies. This analysis uncovers disparities in GF’s effectiveness in attaining these objectives, as well as spatial spillover effects. Notably, GF’s promotion of carbon-neutral goals follows a nonlinear pattern, emphasising the complexity of the relationship. Additionally, green innovation emerges as a mediating force within the GF-driven process of carbon neutralisation (CN). These conclusions hold important policy implications for expediting CN realisation and improving global climate conditions, ultimately contributing to the sustainable development of enterprises.

  • Internal and external factors motivate Generation Z's sustainable apparel consumption in China   Order a copy of this article
    by Li Zhang, Xiao Huang 
    Abstract: Recognising the escalating importance of sustainable apparel consumption among China’s Generation Z, this study integrated the theory of reasoned action with Rogers’ innovation-decision process to examine the influences of internal (past sustainable behaviours) and external (subjective norms) antecedents on consumers’ purchase intentions for sustainable apparel. This study also examined the persuasive mechanisms that mediated the relationships between these antecedents and purchase intentions, namely attitudes toward purchasing sustainable apparel and sustainable self-identity. Data was collected through an online survey from a convenience sample of 577 college students in China. The structural equation modelling results indicated that only subjective norms had a direct influence on Generation Z’s purchase intentions. Notably, both attitudes and sustainable self-identity mediated the influences of Generation Z’s past sustainable behaviours and subjective norms on purchase intentions. This study extended the utilisation of the theory of reasoned action and the innovation-decision process, offering valuable insights for marketers and policymakers.

  • Managerial myopia and low-carbon transition development: evidence from listed companies   Order a copy of this article
    by Fake Ma, Huili Li 
    Abstract: Perception of management holds paramount importance in guiding the metamorphosis and advancement of enterprises. Drawing upon a fresh research perspective centred around managerial myopia (MM), this paper delves into the profound impact of such myopia on the low-carbon total factor productivity of enterprises. The study reveals several noteworthy findings: firstly, the influence of MM on enterprise low-carbon total factor productivity exhibits a pronounced negative trend, signifying that myopia acts as a hindrance to the progression of enterprise low-carbon transformation. Secondly, the effect of MM on enterprise low-carbon total factor productivity displays distinctive heterogeneity, with myopia particularly prominent in its hindering effect on state-owned and mature enterprises. Thirdly, the impediment posed by MM on the development of enterprise low-carbon endeavours stems from declining R&D intensity, reduced environmental protection investments, and weakened human capital. Lastly, the key to breaking free from the constraints of MM in fostering low-carbon transformation lies in the proactive disclosure of environmental information and the fortification of internal control mechanisms.

  • Factors influencing consumers intended and actual sustainable purchases of clothing in Germany and South Africa   Order a copy of this article
    by Boitumelo Pooe, Thomas Dobbelstein 
    Abstract: This paper aims to determine factors that influence consumers’ intentions to purchase clothing sustainably, then determine factors that influence consumers’ actual sustainable clothing purchases, and lastly, analyse the intention-behaviour gap of consumers when purchasing clothing sustainably. With a quantitative approach, an online survey was distributed in Germany (550) and South Africa (555) based on quota sampling. The independent variables analysed were the sustainability core-values of consumers, namely prioritisation, planning/habits, commitment/sacrifice and knowledge/information. Additionally, consumers’ clothing preferences, such as exclusivity, functionality, price-insensitivity and aesthetics, were further independent variables. Dependent variables were the intentions and the actual sustainable purchases of clothing. Results indicated that sustainability core-values were the most significant factors impacting consumers’ intentions and actual sustainable clothing purchases. Furthermore, the intention to purchase clothing sustainably was a vital factor influencing actual sustainable purchases. This was confirmed as the final outcome demonstrated a minimal intention-behaviour gap in both countries.

    Abstract: To address issues related to insufficient monitoring coverage, inaccurate measurement of pollution concentration, and inadequate load monitoring using traditional methods, an intelligent monitoring method for agricultural non-point source pollution based on remote sensing image changes is proposed. Utilising Landsat ETM+ remote sensing imagery, a multi-layer perceptron algorithm is employed to detect and identify agricultural non-point source pollution areas. The Min-Cut algorithm is used for remote sensing image segmentation of agricultural non-point source pollution targets. Remote sensing image changes are detected based on the segmentation results and difference diagram. Intelligent monitoring of agricultural non-point source pollution is achieved by combining the detection results of remote sensing image changes with relevant monitoring indicators. Experimental findings demonstrate that the proposed method achieves a monitoring coverage rate exceeding 96.3%, the mean accuracy of pollution concentration monitoring is 97.1%, the maximum accuracy of pollution load monitoring is 99.3%.
