This study examines how green credit policies, specifically the green credit guidelines (GCGs) implemented in 2012, influence corporate sustainable innovation. This study employs a quasi-natural experiment approach, utilizing data from Chinese listed companies between 2005 and 2023, to examine the differential impact of the GCGs on high-polluting enterprises versus energy-efficient enterprises. The study uses a Difference-in-Differences (DID) methodology to explore how policy-induced changes in financing conditions affect firms’ innovation behaviors, particularly in terms of green patent applications. This study uses a mechanism to understand the role of R&D investment and access to long-term financing in driving these changes. And this study considers heterogeneity across firm ownership types and industry competition to investigate the varying effects of the GCGs. By identifying the causal pathways through which green credit policies influence innovation, this study contributes to the understanding of how environmental policies shape corporate behavior and innovation outcomes.

The global shift toward decarbonization and the rise of the digital economy are compelling manufacturing firms to undergo a complex twin transformation across their structures, operations, and value chains. Business model innovation (BMI), especially in digital servitization (DSBMI), emerges as a crucial catalyst in facilitating this change. However, there is a lack of systematic exploration of how DSBMI influences corporate decarbonization (CD). To fill this knowledge gap, a comprehensive qualitative meta-analysis of 27 case studies was conducted, identifying multiple DSBMI practices for CD employed by industrial firms. These practices can be summarized into three main types: efficiency DSBMI, novelty DSBMI, and convergent DSBMI. A system has at least two of these, while all three may coexist. Based on dynamic capabilities theory, this study also introduces six roles for the three types of DSBMI practices, which interact to help firms sense opportunities, seize them through BMI, and transform their operations and ecosystems—collectively enabling decarbonization through internal optimization (efficiency DSBMI), downstream innovation (novelty DSBMI), and value chain-wide cooperation (convergent DSBMI). The findings offer a comprehensive theoretical framework that guides companies to achieve economic benefits while advancing their CD goals through multi-level BMI strategies. Finally, the study discusses its limitations and proposes directions for future research. Full article

Portland cement (PC) is widely regarded as a cost-effective and reliable binding material for the stabilization and solidification of municipal solid waste incineration fly ash (MSWI FA). However, the soluble salts and heavy metals present in MSWI FA retard PC hydration, thereby limiting the amount of fly ash that can be incorporated. The present study investigates the feasibility of normalizing the hydration of PC-based mixtures containing MSWI FA by applying a fly ash pre-granulation step with 25% PC, followed by coating the resulting granules with a geopolymer layer to reduce the release of harmful ions during the early stages of hydration. Isothermal calorimetry, TG/DTA, XRD, SEM, and mechanical testing were used to investigate the hydration characteristics of composites containing such granules and to assess their properties at 7, 28, and 90 days. It was found that a 20% substitution of PC with the studied FA disrupted PC hydration within the first 48 h. In contrast, both types of granules exhibited the main exothermic peak within the first 10–12 h, with hydration heat release (about 300 J/g) comparable to that of sand-containing references. Uncoated granules exhibited more active behavior with hydration kinetics similar to pure cement paste, whereas the effect of geopolymer-coated granules was close to sand. TG/DTA revealed reduced calcite content in mixtures containing granules, whereas uncoated granules promoted greater portlandite formation than the sand-based system. Hardening the samples under wet conditions resulted in the development of a dense cement matrix, firm integration of the granules, redistribution of chlorine and sulfur ions, and mechanical properties that reached at least 93% of those of the sand-containing reference, despite a lower density of ~4.5%.

Mechanical damage and microbial contamination are major challenges in the postharvest logistics of perishable fruit. In this study, two types of functionally modified chitosan-based aerogel pads were developed to enhance cushioning and preservation of wax apples. A chitosan/polyvinyl alcohol (CP) aerogel was first optimized by adjusting solid content, CS:PVA ratio, and crosslinker concentration. The optimal formulation (2% solids, 1:1 CS: PVA, 3% glutaraldehyde) exhibited a uniform porous structure and improved compressive strength. A chitosan/montmorillonite (CM) aerogel with 5% montmorillonite (MMT) showed high porosity, low density, and excellent cyclic stability. Incorporating 10% copper nanoparticle-loaded antibacterial fibers (CuNPs-TNF) into CM aerogels yielded CM-Cu aerogels with enhanced cushioning and antimicrobial properties. Under simulated transport and cold storage conditions, all aerogel-packaged groups reduced mechanical damage and decay of wax apples. Compared to the control, the CM-Cu group showed 66% lower decay, 5% less weight loss, 6 N greater firmness, 7% less juice yield, and a 13% reduction in relative electrical conductivity. Additionally, it better preserved fruit color and total soluble solids, extending shelf life by 4 d at 20 °C. These results demonstrate the potential of chitosan-based aerogels as multifunctional packaging materials that combine mechanical protection with antimicrobial activity for perishable fruit preservation.

This study aimed to evaluate the efficacy of a palm oil-free structured lipid (SL) as a lipid base in sandwich-type cookie fillings. SL was enzymatically interesterified from a blend of soybean oil, high-oleic peanut oil, and crambe hard fat (34:34:32). Four fillings (30% fat) were prepared using either SL or commercial shortening (CS), with processing by mixer (F1, F2) or ball mill (F3, F4). Commercial sandwich cookies were included as a reference Standard. SL exhibited an improved lipid profile, containing up to 14% less saturated fatty acids, higher levels of monounsaturated (34.5%), and increased long-chain fatty acids (~18% C22:0). Physicochemical analyses were conducted over a storage period of 180 days, including evaluations of texture, particle distribution, color, water activity, oil loss, and oxidative stability. Among the formulations, F4 demonstrated the highest firmness (at ~121.1 N) and the smallest D₅₀ (~80 µm). However, it also exhibited lower oxidative stability (induction period: ~6.75 to 14.6 h) compared to CS-based fillings (~36 to 42.5 h), along with a higher oil loss (≥4.7%). Sensory of F4 yielded an overall acceptance index ≥ 70%, though it received lower scores for waxiness. Overall, the SL showed promising potential as a structuring fat in the fillings. Full article

This study explored an eco-friendly coating system combining seagrass-derived cellulose fiber (SCF) from Cymodocea rotundata with marine type I collagen (MC) for tomato preservation. The SCF/MC composite was prepared through enzymatic and natural crosslinking processes and subsequently characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), and thermogravimetric analysis (TGA). The results demonstrated that SCF/MC possessed a compact morphology, strong hydrogen bonding interactions, high crystallinity, and excellent thermal stability. When applied as a coating, SCF/MC composite significantly reduced weight loss in tomatoes, preserved firmness (>39 Units), regulated acidity, maintained moisture levels (~90%), and delayed increase in pH compared to the uncoated control. Additionally, the SCF/MC coating sustained ascorbic acid and moderated lycopene accumulation, indicating delayed ripening. At 0.5% of SCF/MC composite, spoilage was limited to 22% versus ~80% in control samples, demonstrating a substantial reduction in decay. Antifungal assay showed strong inhibition of Aspergillus flavus, with the highest suppression of mycelial growth observed at 0.5% of SCF/MC. Overall, the SCF/MC coating effectively enhanced fungal safety and maintained the physicochemical quality of tomatoes, thereby extending shelf life while valorizing seagrass biomass as a sustainable postharvest resource.

As enterprises increasingly depend on software systems, security defects such as vulnerability disclosures, exploitations, and misconfigurations have become economically relevant risk events. However, their short-term impacts on capital markets remain insufficiently understood. This study examines how different types of software security defects affect short-horizon stock market behavior. Using a multi-model event-study framework that integrates the Constant Mean Return Model (CMRM), Autoregressive Integrated Moving Average (ARIMA), and the Capital Asset Pricing Model (CAPM), we estimate abnormal returns and trading-activity responses around security-related events. The results show that vulnerability disclosures are associated with negative abnormal returns and reduced trading activity, while exploitation events lead to larger price declines accompanied by significant increases in trading activity. Misconfiguration incidents exhibit weaker price effects but persistent turnover increases, suggesting that markets interpret them primarily as governance-related issues. Further analyses reveal that market reactions vary with technical severity, exposure scope, industry context, and firm role, and that cyber shocks propagate through both price adjustment and liquidity migration channels. Overall, the findings indicate that software security defects act as short-term information shocks in financial markets, with heterogeneous effects depending on event type. This study contributes to the literature on cybersecurity economics and provides insights for firms, investors, and policymakers in managing software-related risks. Full article

The aim of this study was to investigate the effect of gibberellins on the setting and quality of parthenocarpic apples (Malus × domestica Borkh.). The experiment was conducted in 2021 on the ‘Golden Delicious’ cultivar in the Warsaw University of Life Sciences experimental orchard. During the trial, we compared the effect of various gibberellins, such as GA₃, GA₄₊₇, and a mixture of GA₃ + GA₄₊₇. These gibberellins were administered to both intact and mechanically injured flowers (damaged by emasculation and style removal) at the pink bud stage. The results clearly demonstrate that gibberellins applied during blooming supported the induction of parthenocarpic fruit setting in Golden Delicious apples; however, fruitlet retention remained significantly lower than in natural pollinated flowers. The most efficient treatment among emasculated flowers was the mixture of GAs, resulting in a final fruit retention of 23.6%. Fruit size and morphology differed across treatments: GA₃ applied on intact flowers resulted in the largest parthenocarpic fruits, while the GA₄₊₇ and GAs mixture promoted a more elongated fruit shape. Moreover, gibberellin treatment affected other fruit quality traits. Almost all GA treatments led to a higher soluble solids content in fruits. In addition, apples derived from intact flowers treated with GA₃ showed reduced firmness. Overall, our findings indicate that gibberellins can support fruit set, even when flowers are injured, and to lower extent modify fruit quality, but the results depend on flower condi-tions and the type of GA used.

Personality type tools have been utilized to explain human behavior by organizing, classifying, and categorizing individuals into distinct personality types. Alternatively, problem-solving methods have been employed throughout project life cycles to enhance problem solving across all levels of the organizational workforce. This study evaluated the influence of personality tools and methods for problem solving on project success. The population comprised 29 active project managers employed in the engineering section of a large manufacturing firm, focusing on sustainable development projects. Quantitative study, through correlational analysis, demonstrates that personality tools facilitate the formation of effective project teams (p < 0.05) and that problem-solving methods significantly improve the likelihood of successful project completion (p < 0.05). This research presents a novel approach and a decision framework for projects that identify the preferred methods for solving problems associated with various MBTI profiles, and demonstrate that where MBTI is utilized as a guiding tool for effective project team formation, ESTJ, ENTJ, ISTJ, and INTJ are prioritized profiles. The research concludes that selecting methods for solving problems according to the nature of the problem impacts overall project success, with the Five Whys methodology contributing when used for root cause analysis. Therefore, it is essential to enhance project managers’ awareness that specific tools and methodologies can aid in the formation of teams that successfully complete projects. Full article

Excessive sugar consumption has emerged as a significant public health concern, leading to growing interest in non-caloric, high-intensity sweeteners (HIS) as alternatives to conventional sugars. Cherry tomatoes, although inherently rich in lycopene, vitamin C, organic acids, and other health-promoting metabolites, are nonetheless perceived as insufficiently sweet by some consumers, particularly younger ones. Hence, sweeter fresh tomato options such as “stevia tomato” have recently gained popularity in Korea. Despite this trend, the effects of infusing HIS into fresh tomatoes on postharvest quality attributes, physiological responses, and sensory perception remain largely unexplored. To address this gap, this study investigated the effects of vacuum infusion of four HIS (glucosyl steviol glycosides (GSG), sucralose (SUC), acesulfame potassium (ACE), and sodium saccharin (SAC)) on the postharvest quality and ripening behavior of ‘TY Nonari’ cherry tomatoes. Fruits were infused under vacuum (0.2 bar, 23 °C) and analyzed for firmness, weight loss, ethylene production and respiration rates, colorimetric attributes, physico-chemical properties (TSS, TA, pH, TSS/TA), sensory quality, and microstructural characteristics using field emission scanning electron microscope (FE-SEM) coupled with energy-dispersive X-ray spectroscopy (EDS). Sweetener type significantly influenced tomato performance after vacuum infusion. GSG- and SAC-treated tomatoes exhibited the most rapid softening, with firmness decreasing from 10.25 to 5.66 N and from 9.97 to 5.53 N, respectively, by day 4. In contrast, ACE-treated fruit retained the highest firmness, decreasing from 9.62 to 7.89 N, followed by SUC, which declined from 10.00 to 6.67 N. Weight loss was also the highest in GSG (9.59%) and ACE (7.32%), whereas SUC (2.97%) and SAC (2.36%) showed markedly better water retention. Microstructural analysis corroborated these results: SAC-treated tomatoes exhibited severe cell wall degradation, with thickness decreasing from 8.22 to 4.24 μm, while GSG-treated fruit showed noticeable thinning from 8.33 to 6.39 μm. ACE maintained the thickest cell wall, decreasing from 8.83 to 7.19 μm, with SUC displaying intermediate preservation from 8.43 to 6.63 μm. Overall, ACE was the most effective treatment for preserving sensory quality, micro-structural integrity, and physicochemical attributes. These findings provide a scientific basis for selecting appropriate HIS to develop low-sugar, high-quality fruit products tailored to evolving consumer preferences. Full article

Environmental, social, and governance (ESG) disclosure has gained global prominence, yet its implementation in emerging markets particularly in environmentally intensive sectors remains fragmented. In Indonesia’s energy industry, ESG transparency still struggles to meet rising global expectations, especially amid increased foreign investment flows and sustainability demands following the country’s G20 presidency. While prior research has separately examined financial performance and ownership structure, fewer studies have explored their combined impact on ESG disclosure within this institutional context. This study investigates how financial risk indicators and ownership composition influence ESG disclosure levels among publicly listed energy firms in Indonesia during the 2020–2024 period. Drawing on 98 firm-year observations, ESG performance is measured using the Nasdaq ESG Reporting Guide, and multiple linear regression is used to assess the influence of return on assets, liquidity, and various ownership types (managerial, institutional, and foreign), controlling for firm age and COVID-19 impact. The findings reveal that institutional ownership significantly enhances ESG disclosure, while other predictors such as return on assets, liquidity, managerial, and foreign ownership show no meaningful effect. The results underscore the role of institutional investors as key drivers of ESG adoption, offering insights into how ownership structures shape sustainability reporting in a high-impact sector of an emerging economy.

Following and imitating others’ digital innovation decisions is not always grounded in rational judgment; it may also arise from blind conformity, reflecting a “herding behavior”. Drawing on a panel dataset of Chinese listed firms from 2010 to 2022, this study takes firms in the same industry as the reference group to investigate the existence, driving mechanisms, and economic consequences of corporate digital innovation convergence. The findings show that both breakthrough and incremental digital innovation exhibit convergence at the firm level and are jointly driven by information transmission, market competition, and resource dependence. However, the economic consequences of these two types of innovation convergence differ significantly. The convergence of breakthrough digital innovation enhances firms’ total factor productivity, return on equity, and capital market value, representing a positive peer effect, whereas the convergence of incremental digital innovation weakens these core indicators, reflecting a herding behavior. The heterogeneity analysis indicates that breakthrough digital innovation convergence is more pronounced in regions with stronger intellectual property protection and in industries with higher technology intensity, while incremental digital innovation convergence is more pronounced among private firms and in industries with lower technology intensity. Our findings provide valuable insights into the interactive dynamics of corporate digital innovation decisions and carry important implications for both theory and practice. Full article

The growing relevance of sustainable finance has positioned green bonds as central instruments in debates on how capital markets can contribute to climate transition while creating value for firms. This article conducts a literature review to examine the relationship between green bond issuance, corporate financial performance, and the cost of debt. Using the PRISMA 2020 protocol, 59 articles published between 2019 and 2025 were identified and classified according to study type, methodological approach, analytical technique, sectoral and geographic focus, and performance indicators. A bibliometric analysis was also performed to map publication trends, research clusters, and thematic evolution. The results indicate a fragmented but expanding field, with most studies concentrated in developed markets, especially Europe, the United States, and China, and limited evidence from emerging economies. Empirical findings converge on modest but heterogeneous financial benefits, frequently reflected in the so-called “Greenium,” typically ranging between 1 and 63 basis points. Accounting-based effects on profitability (ROA, ROE) remain mixed, while econometric/regression, panel analysis and event studies dominate the empirical landscape. The paper’s incremental contribution lies in consolidating these quantitative insights into a reproducible classification framework that enables systematic comparison between developed and emerging markets, supporting future research on long-term financial and sustainability outcomes.

Wind power has become a strategic cornerstone of China’s renewable-energy transition and industrial upgrading, making it essential to understand how policy interventions shape the behaviour of its industry chain. This study examines how major wind power policies issued between 2015 and 2024 transmit shocks across nine upstream, midstream, and downstream sectors. Using four contagion tests based on higher-order co-moments, combined with a policy sensitivity index, the analysis identifies distinct transmission patterns across policy types. The results show that market-mechanism reforms induce the strongest and most systemic contagion effects, reflecting their ability to align financial incentives with renewable-integration objectives. Upstream sectors—particularly equipment and key material industries—exhibit the highest responsiveness, while midstream construction and downstream operation and maintenance display more moderate and delayed adjustments. Development and construction policies generate broader but less intensive contagion, whereas industry-support measures trigger selective, sector-specific responses. These findings offer practical guidance for improving policy coordination, investment planning, and industrial upgrading within China’s wind power value chain. Future research could extend the analysis by incorporating firm-level data, longer policy cycles, and interactions with other structural shocks such as electricity-market reforms and climate-related risks.

The characterization of alternative starch sources is crucial for industrial applications. This study evaluated starches from turmeric (Curcuma longa L.) and mangarito (Xanthosoma riedelianum), considering extraction yield, proximate composition, amylose content, morphology, hydration properties, viscoamylographic behavior, and crystalline and thermal characteristics. Mangarito starch showed a higher yield (11.6%) than turmeric starch (5.6%). Turmeric granules were heterogeneous (triangular, ellipsoidal, oval), while mangarito granules were predominantly rounded. Turmeric starch exhibited higher amylose content (55.1%) compared to mangarito starch (25.9%). Hydration and viscoamylographic analyses indicated that turmeric starch had higher solubility (2.36%) and water absorption (2.88 g/g), higher peak viscosity (3147.5 cP), lower breakdown (83.5 cP), and greater retrogradation tendency (9806 cP). In contrast, mangarito starch demonstrated enhanced thermal stability (breakdown 1824 cP; final viscosity 4763.5 cP). X-ray diffraction revealed a semicrystalline A/B-type pattern for turmeric starch and a predominantly A-type crystalline structure for mangarito starch. DSC indicated glass transition temperatures of 114.7 °C (turmeric) and 120.1 °C (mangarito), while TGA confirmed greater thermal stability for mangarito starch, with a narrower decomposition range and higher residual mass. These results suggest that turmeric starch, due to its high amylose content, is suitable for rapid gelatinization and firm gel formation, whereas mangarito starch is more appropriate for applications requiring superior thermal stability and structural integrity.
