Small-scale fisheries are significant sources of nutrition and livelihood globally. However, increasing anthropogenic activities in coastal areas of developing countries have threatened the sustainability of artisanal fisheries and species. Fisheries of Sardinella maderensis, towards the global stock of which Nigeria contributes 9% and which is a significant livelihood source in the coastal communities of Ibeju-Lekki, Lagos, faces sustainability threats. This research investigated the effects of anthropogenic activities on S. maderensis fisheries in the coastal areas of Ibeju-Lekki, Lagos, Nigeria. The study adopted a mixed-method approach involving qualitative and quantitative research methods. These included species identification, water quality analysis, land-use change analysis, field surveys, focus group discussions, and interviews. Genetic analysis of the fish samples from the study area revealed that the species had a mean of 98% similarity to S. maderensis. While major urban and industrial land use has increased by 175% in the last four decades, the catch per unit effort (CPUE) of S. maderensis declined monthly to 0.0072 kg/H between 2003 and 2019. Linear regression indicated that anthropogenic variables explained approximately 39.58% of the variation in the CPUE (p < 0.001, R2 = 0.40). Water samples showed that heavy metal levels were above international limits, with high total petroleum hydrocarbon (TPH) pollution in all stations (27.56 mg/L–3985.40 mg/L). Physiochemical analysis of water samples indicated TDS levels higher than the acceptable limits (mean = 24,971.1 mg/L) and inadequate chlorophyll-a levels (mean = 0.01 µg/L). Hence, urgent strategies are required to mitigate anthropogenic threats through inclusive coastal management policies supporting resilient artisanal fisheries.

This research focuses on the significant role of Corporate Social Responsibility (CSR) in shaping employees’ behavior towards the reduction of food waste in the hospitality industry that has been under scrutiny for its environmental impact. The study aimed at understanding how CSR, coupled with employees’ moral attitudes, admiration for their organization, and climate change awareness influences sustainable practices by realizing the complex interplay between company initiatives and personal psychology. The participants were staff members who worked in several hotels in China where there were active CSR programs. Using established scales, we collected 422 valid responses over three waves to strengthen our data collection process. Empirically, it was found that CSR directly influenced food-waste-reduction behavior. Additionally, it was discovered that this relationship was mediated by moral attitudes and employee admiration as well as moderated by awareness of climate change. The findings have substantial theoretical implications regarding the interaction between emotional and cognitive factors within the CSR framework to influence behavior among employees. This paves the way for creating well-rounded strategies that appeal to staff and encourage sustainability in the hotel business. While focused on China’s hospitality industry, this research creates room for future studies in other places around the world using various methods. The conclusions drawn underline the critical role of CSR in promoting environmental sustainability in the hospitality industry, providing a pathway for organizations to engage employees in meaningful and impactful sustainability initiatives.

Predicting and assessing the vitality of public urban spaces is crucial for effective urban design, aiming to prevent issues such as “ghost streets” and minimize resource wastage. However, existing assessment methods often lack temporal dynamics or heavily rely on historical big data, limiting their ability to accurately predict outcomes for unbuilt projects. To address these challenges, this study integrates previous methodologies with observations of crowd characteristics in public spaces. It introduces the crowd-frequency hypothesis and develops an algorithm to establish a time-dimensional urban vitality dynamic prediction model. Through a case study of the Rundle Mall neighborhood in Adelaide, Australia, the effectiveness of the prediction model was validated using on-site observation sampling and comparative verification. The prediction model framework allows for the determination of urban vitality within specific time ranges by directly inputting basic information, providing valuable support to urban planners and government officials during the design and decision-making processes. It offers a cost-effective approach to achieve sustainable urban vitality construction. Furthermore, machine learning techniques, specifically the decision tree model, were applied to case data to develop a set of preliminary algorithm tools, which enable output of reference urban vitality levels (high-medium-low).

How does a firm’s value chain digitalization contribute to its innovation in value chains? This study investigates innovation activities in value chains from a combination of distributed innovation perspective and technology affordance theory. We posit that a digital value chain (DVC) plays a pivotal role in driving distributed innovation in value chains. Our focus is specifically directed toward exploring the interconnected dynamics of the DVC, global value chain (GVC), and diversification strategy, elucidating the influence of their interactions on a firm’s distributed innovation in value chains. Leveraging the data of 862 manufacturing firms from the World Bank Enterprise Survey (WBES) in China, our empirical analysis reveals several key findings: (1) value chain digitalization positively influences distributed innovation in value chains and GVC embeddedness, (2) GVC embeddedness enhances distributed innovation in value chains, and (3) product diversification serves as a positive moderator, strengthening the effects of both value chain digitalization and GVC embeddedness on distributed innovation in value chains. In summary, this paper deepens our understanding of the relationships between DVC, GVC, diversification strategy, and distributed innovation in value chains. Our research provides theoretical and policy implications for digitalization and innovation strategies which are significant sources of sustainable development for firms and GVCs.

Nowadays, introducing innovations is treated as a necessity to ensure market survival. However, this may be difficult, especially for food entrepreneurs whose innovations are strongly connected with tradition. The main aim of this study was to assess the innovation abilities and potential of traditional food producers in the context of the classic dilemma of innovation-and-tradition interplay. The surveyed food producers were from five Polish voivodeships belonging to the European Culinary Heritage Network. The study conducted 70 semi-structured interviews. The respondents were divided into two groups: the innovative and non-innovative groups. The statistical significance of the differences between the two groups was tested using a two-independent-samples t test. A comparison revealed significantly different average results for the following variables: general managerial education, business duration, sources of knowledge about traditions, profits and earnings, and own product brand. For the remaining variables (employment, sales range, financial capital sources, business goals in total, and own business), no significant differences were found between the mean results. Both tested hypotheses were verified to be valid. The vendors-producers of traditional food in this study showed innovative abilities and untapped innovation potential.

Agriculture plays a significant role in economic development and livelihood and is a key contributor to food security and nutrition. However, global concerns regarding the sustainability of the agricultural sector (mainly environmental damage) is linked to agricultural activities such as greenhouse gas (GHG) emissions, water pollution, and loss of biodiversity. The aim of this study was to assess the effectiveness of ORUN® (a formulated agricultural chemical mixture) to reduce N2O emissions from urine patches and to improve pasture yield, pasture N uptake, and soil mineral N concentrations. The field trials were conducted during the spring of 2015 on dairy urine patches at Massey University, New Zealand. Treatments consisted of control nil urine, control nil urine + ProGibb®, urine only, urine + ProGibb®, urine + ORUN®, and urine + ORUN PLUS® replicated four times in a randomized complete block design. At 31 days after treatment (DAT), analysis of soil samples in 0–5 cm soil profiles showed that urine + ProGibb® significantly (p = 0.0041) increased the soil nitrate concentration (121.40 kgN/ha) compared with 48.15 kgN/ha from urine only. The urine + ProGib® treatment produced significantly lower herbage N recovery (35% of applied N) compared with the urine only. Throughout the trial period, the urine patches treated with ProGibb® and ORUN® produced significantly higher N2O fluxes compared with urine only and urine + ORUN PLUS®, as well as higher surface soil nitrate and mineral N concentrations.

Environmental, social, and governance (ESG) ratings are gaining momentum in China, but their capacity to induce green innovation among heavy polluters remains to be proven. Based on the green patent data from listed heavy-polluting enterprises in China from 2010 to 2020, this paper empirically analyzes the mechanism of ESG ratings and their impact on green innovation using a multi-temporal double-difference method. The findings indicate that ESG ratings effectively promote green innovation in heavily polluting firms. The mechanism test reflects that ESG ratings can enhance the enterprises’ green innovation capacities by alleviating their financing constraints and enhancing their corporate risk-taking abilities. Further analysis reveals that the incentive effect of ESG ratings on green innovation lies in considering both source control and end-of-pipe management by addressing their environmental responsibilities and actively engaging in green innovation activities. This facilitative effect is more significant in non-state-owned enterprises (NSOEs) and large-scale enterprises. Overall, these insights provide empirical evidence to advance green innovation in heavy-polluting enterprises.

Geopolymer concrete (GPC) is a novel and environmentally friendly type of concrete that eliminates the use of cement, resulting in a significant reduction in carbon emissions and a more sustainable construction material. Alkaline activators are used in GPC to achieve rapid strength development. The most popular alkaline activators are sodium/potassium silicate and sodium/potassium hydroxide, which are known contributors to carbon emissions, hence limiting the advantages of GPC; therefore, reducing the amount of these alkaline activators that contribute to carbon emissions is necessary for developing a more sustainable geopolymer concrete. In this study, the influence of the variation in sodium hydroxide molarities on the performance of fly ash/sugarcane bagasse ash-based-geopolymer concrete was investigated. The different molarities used were 10 M, 12 M, 14 M, and 16 M sodium hydroxide solutions. In addition, the effect of sugarcane bagasse ash content (0%, 5%, 10%, 15%, and 20%) on the fresh and hardened geopolymer concrete properties were examined. The slump test, compression test, split tensile test, and flexure test were conducted on the cast samples. The results of this study showed that raising the concentration of NaOH from 10 M to 16 M while maintaining a sodium silicate to sodium hydroxide ratio of 2.5 resulted in a 3.75–10.2% improvement in compressive strength after 28 days. It is worth noting that, even at a concentration of 10 M, the concrete still achieved high strength.

This paper looks into the determinants of national innovation performance from the perspective of policy regime and establishes a theoretical model on how a country’s dual Science, Technology, and Innovation (STI) policy regimes, democratic and meritocratic, and national absorptive capacity (NAC) jointly determine its national innovation performance. A democratic STI policy regime promotes innovation through channels of freedom, social equality, and public participation. A meritocratic STI policy regime promotes innovation through channels of good governance and rational policymaking. The model further proposes that the relationships between STI policy regimes and national innovation performance are moderated by potential NAC (PNAC) and realized NAC (RNAC) in opposing directions. The fixed-effects panel regression of OECD countries confirms that both democratic and meritocratic STI policy regimes have positive effects on national innovation performance. Moreover, the democratic effect is positively moderated by PNAC but negatively moderated by RNAC. In contrast, the meritocratic effect is positively moderated by RNAC but negatively moderated by PNAC. The major contribution of this paper is to highlight the importance of a country’s STI policy regimes as the bedrock and NAC as the leverage to generate more homegrown innovations.

This study explores the relationship between Environmental, Social, and Governance (ESG) practices and the market value of companies, with a focus on Brazil’s largest corporations. Recognizing the limitations of existing research tools for analyzing the impact of ESG factors, we introduce an innovative, open-source Dictionary of ESG Terms. This tool is designed to classify news content into the detailed categories established by the Sustainability Accounting Standards Board (SASB), thereby facilitating a nuanced analysis of ESG-related news and its subsequent effects on stock prices. Our analysis reveals that stock prices exhibit significant positive reactions to favorable ESG news and negative reactions to adverse ESG developments. Crucially, our findings underscore the discernment of investors, who appear to prioritize financially material ESG information over news bearing solely reputational or non-pecuniary significance. This distinction highlights the critical role of financial materiality in shaping market responses to ESG news. By providing empirical evidence from the Brazilian market, this study contributes to the broader discourse on ESG factors in corporate valuation. It offers practical tools and insights for investors, companies, and regulators aiming to better understand the complexities of ESG investment strategies. Through the application of our comprehensive ESG Dictionary, we shed light on the diverse dimensions of ESG impact, suggesting an approach to evaluate how ESG practices influence corporate market value in emerging economies.

Primary health care (PHC) facilities play a significant role in constructing a “people-oriented city” to promote sustainable urban development. However, existing studies exhibit gaps in the spatial-performance evaluation of PHC facilities at the block scale and in identifying spatial association types between facilities and the population. Therefore, we examined the elderly population, who rely heavily on PHC facilities, and developed a spatial-performance evaluation model for PHC facilities at the block scale using the Ga2SFCA method and the bivariate spatial autocorrelation method. The results revealed an evident concentric pattern and spatial mismatch between the accessibility of facilities and the elderly population. Facilities in the central area were inadequate due to the excessive density of the elderly population, whereas medical services in suburban areas were unsustainable due to poor accessibility. From a spatial-justice perspective, the spatial-performance evaluation at the block scale can identify spatial correlation types and distribution characteristics between PHC facilities and the elderly population.

Analysis of the energy consumption of industrial robots during the implementation of a technological task can increase efficiency and minimize production costs, as well as extend the service life of robots, taking into account the rational use of energy sources. An important challenge in designing sustainable production processes is the selection of energy-saving technological equipment supporting the work of robots. Additionally, optimization of robot program codes, including parameters and robot movement paths, determines the energy efficiency of the robotic station. Welding is one of the most popular areas of process robotization due to its ability to increase production efficiency and improve the quality of part assembly compared to manual work. In these studies, an exemplary process of robotic welding of aluminum alloy parts was designed, analyzed, and optimized with an orientation towards sustainable development guidelines. This work also presents a review of current publications discussing the authors’ contribution to achieving energy efficiency in robotic welding processes. The purpose of this analysis is also to indicate directions for the development of future research work in order to minimize energy consumption in production processes with an appropriate level of product quality and increase production efficiency.

With the continuing rise of attention towards societal challenges like, e.g., climate change, Corporate Social Responsibility (CSR) becomes an increasingly important topic for companies. While there is no question that CSR activities are on the rise, the connection towards Earnings Management in companies is less clear. Therefore, this research paper not only aims to provide an up-to-date picture on the literature addressing this interconnection, but also provides a profound base for a more solid theoretical framework. Thus, it delivers a critical basis for further empirical analyses in this field. In order to illustrate this interconnection between those two topics, this paper presents an SLR analysis of articles published in the Chartered Association of Business Schools (CABS) or Australian Business Deans Council (ABDC), focusing on empirical analyses of CSR performance and Earnings Management. Overall, it can be stated that CSR performance has a negative influence on Accrual-Based Earnings Management, while findings on the influence on Real Earnings Management are contradicting. Furthermore, the relationship of CSR performance and Accrual-Based Earnings Management/Real Earnings Management is especially vague when the used methods are moderated by different variables such as family involvement or managerial entrenchment. While the connection between Accrual-Based Earnings Management and CSR performance is widely covered in the existing literature, the relationship between Real Earnings Management and CSR performance is clearly less outlined. This research paper makes key contributions to the existing literature, as it combines and structures results of conducted studies during the last ten years and elaborates on the differences on commonalities of the results. This analysis also suggests that other factors that possibly influence Earnings Management or CSR should be included in a future research model for upcoming analyses. It places the findings of earlier studies into the context of the Ethical Approach, creating a roadmap for the future.

The rapid economic development in the Chengdu–Chongqing Economic Circle (CCEC) has exerted significant pressure on the ecological environment of the Sichuan–Chongqing Region in China. Balancing ecological protection and economic development has become an imperative challenge that needs to be addressed. In this study, we employed land use/cover data and environmental threat factors to construct Ecological Security Patterns (ESPs) for the CCEC using the InVEST model and Circuit Theory. The research findings revealed the following key outcomes: (1) The total area of suitable habitat in the CCEC was 208,728.3 km2, accounting for 87.14% of the study area. Habitat quality exhibited regional variations, with higher quality habitats predominantly found in the western and northeastern parts, and lower quality habitats in the central region. (2) The CCEC consisted of areas with low, medium, high, and optimal habitat quality, spanning 140,912.18 km2, 15,341.89 km2, 15,578.38 km2, and 36,895.85 km2, respectively. These areas accounted for 58.83%, 6.40%, 6.50%, and 15.40% of the study area, respectively. (3) The ESPs in the CCEC encompassed 22 ecological nodes, 36 clusters of ecological corridors, and 136 ecological sources. Ecological corridors served as radial connections, linking each ecological node and ecological source along mountain ranges, forested areas, river networks, and valleys. (4) The core ecological regions forming the ESPs of the CCEC included the Qionglai–Minshan–Longquan Mountains in the west, Tiefeng–Fangdou–Qiyue–Wushan Mountains in the east and northeast, and Dalou Mountain in the southeast. These regional-scale findings provide valuable insights for policymakers to implement targeted measures for ecological protection and promote green development. They offer objective guidance and constraints for managing urban expansion and anthropogenic activities, ultimately enhancing the ecological security level of the CCEC.

The increasing demand for freight services and the use of larger vessels to meet this demand has led to challenges related to storage space and logistics activities, highlighting the need for improvements in port infrastructure for better logistics management. At a crucial phase in its growth, the Port of Trois-Rivières in Canada is planning a major expansion, including the construction of a new terminal to enhance its hosting capacities and freight services. This expansion faces potential access congestion problems during the planned construction, exacerbated by the port’s urban setting. In response to the needs identified by the port authorities for this event, the study’s objective is to assess the implications of increased construction and freight truck flows on access gate fluidity and the impact of additional access infrastructure investment to mitigate potential congestion. These evaluations aim to define effective access management strategies throughout the construction period of the new terminal. To address these complexities, our approach is based on scenario analysis in variants co-constructed with the partner. These scenarios are evaluated using simulation models, configured according to parameters calibrated with a granularity that allows congestion detection. The results enabled an evaluation of the capability of existing and potential gates to manage access. Subsequently, recommendations were shaped in accordance with the expected objectives to manage access traffic effectively. These recommendations concern the optimization of construction activity planning, the layout and planning of access, and the importance of enhanced collaboration between municipal and port authorities for more controlled road traffic management. Recognizing the importance of synchromodality, road network centrality management, and the outsourcing of capacity through inter-port cooperation and with dry ports to manage congestion, these tools will be discussed in this work. The study proposes an approach that reconciles scientific rigor with the implementation constraints of the proposed solutions, allowing this study wider applicability in various port contexts facing challenges in this field of study.

This paper analyzes the social representation (SR) of sustainable mobility as it emerges from social media networks. The role of social media (SM) as contexts of creation, negotiation, and diffusion of a mobility culture worldwide is discussed, together with the results of an empirical investigation that explored the contents and structure of the discourse on “sustainable mobility” as it emerges from the posts published (in English) on two highly used social media (Facebook and TikTok) platforms during the years 2022 and 2023. First of all, the results confirm the relevance of social media as an indicator of ongoing trends in the evolution of mobility culture and the usefulness of S. Moscovici’s theory of social representations as a theoretical framework for analyzing such trends. In particular, several new trends in the SRs of sustainable mobility were identified. These include, for example, the decline in skeptical views and the rise of more optimistic ones, regarding the feasibility of changing people’s mobility styles worldwide. Such views appear to be fostered by the positive perception of new technological innovations (electric vehicles), as well as by their endorsement by both the business sector and governmental institutions. Practical implications and theoretical indications for future research are also outlined.

Based on the panel data of China’s listed electric power enterprises, this paper adopts the differences-in-differences model to empirically analyze the pilot policy of carbon emissions trading’s impact on the total factor productivity of power enterprises in 2013. The study finds that the carbon trading pilot policy has a significant positive effect on the total factor productivity of power companies, and the two possible impact mechanisms are external cost compensation and additional income, and internal low-carbon technology innovation and resource allocation optimization. The conclusions above have been further confirmed by the parallel trend test and robustness test. The heterogeneity analysis demonstrates that there are differences in the regression results between state-owned enterprises and nonstate-owned enterprises. The possible reason is that state-owned enterprises are more likely to be affected by the carbon emissions trading system, and their asset-heavy model puts greater pressure on carbon emission reduction. Therefore, their demand for low-carbon technology innovation is more urgent; areas with stricter carbon emission verification are more sensitive to the implementation of carbon trading, and a reasonable increase in carbon verification can make the carbon trading market more effective. Based on the research results, this paper proposes to speed up the improvement of the national carbon trading market system, enhance the diversity and richness of the main market, improve the liquidity of the carbon trading market, broaden financing channels for electric power enterprises, and improve the carbon market supervision mechanism.

This study highlights the potential utilization of hydrogen gas in electric arc furnaces for achieving cleaner and more sustainable steel production. The application of hydrogen offers a promising path for reducing carbon emissions, enhancing energy efficiency, and advancing the concept of “green steel”. This study employs a 2D axisymmetric induction-based model to simulate an electric arc under atmospheric pressure conditions. We conducted numerical simulations to compare compressible and incompressible models of an electric arc. The impact of compressibility on hydrogen arc characteristics such as arc velocity, temperature distribution, and voltage drop were investigated. Additionally, different applied current arcs were simulated using the compressible model. When compared to an incompressible arc, the compressible arc exhibits a higher voltage drop. This higher voltage drop is associated with lower temperatures and lower arc velocity. A rise in applied current results in an upward trend in the voltage drop and an increase in the arc radius. In addition, the increased applied current increases the probability of voltage fluctuations. The voltage fluctuations tend to become more extreme and exert more stress on the control circuit. This has an impact on emerging electric arc technologies, particularly those involving the use of hydrogen. These fluctuations affect arc stability, heat output, and the overall quality of processes. Thus, the precise prediction of voltage and the ability to stabilize the operation is critical for the successful implementation of new hydrogen technologies.

This study explores how the layout of neighborhoods in traditional settlements of Saudi Arabia’s Najdi region influence social interactions and urban planning decisions. The study uses a multidisciplinary approach that includes urban morphology, architectural phenomenology, and sociological study methods to investigate the relationships between spatial organization and decision-making processes on both the macro and micro levels of decision-making. The purpose is to look at how collective action decision-making processes affect the urban fabric and how social norms influence spatial organization at different levels. The study applies case study and spatial analysis approaches to investigate how the traditional settlements’ spatial structure promotes peace among the inhabitants while also sustaining cultural traditions. The qualitative approach investigates how spatial arrangements influence behaviors, developing a better understanding of how residents interact with their surroundings. According to the study’s findings, these spatial layouts sustain customs and assist communities in adapting to environmental changes by retaining cultural activities. The study identifies the significance of balancing development with the retention of important traditional values in the implementation of long-term urban conservation plans. Traditional Najdi towns can serve as urban design examples, emphasizing the need to acknowledge the distinct value of vernacular architecture in modern urban development while also fostering social cohesion.
