Eco‐Labels and Sales Mode Selection Strategies for E‐Commerce Platform Supply Chain
Authors: Yao Fengmin , Li Bing , Lv Yang , Qin Xu‐dong 
Published: December 2024

ABSTRACTThe E‐commerce platform supply chain (EPSC) is maturing as a result of the platform economy's growth, and an increasing number of eco‐friendly producers are joining E‐commerce platforms to increase the sales of their eco‐friendly goods. However, without an information disclosure mechanism, customers find it challenging to completely comprehend or grasp the green information on items. Eco‐labels, as a green declaration symbol, can effectively reduce the information asymmetry between consumers and manufacturers. This paper establishes four game models for the EPSC under industry and government labels, considering the reselling and agency selling modes. The effects of consumers' green perceptions, eco‐label credibility, and R&D cost coefficient on the operation of EPSC, consumer surplus, environmental quality improvement, and social welfare were analyzed. We find that the enhancement of consumers' green perceptions and eco‐label credibility are beneficial for improving the product's greenness, increasing the profit of the E‐commerce platform, consumer surplus, environmental quality improvement, and social welfare, but it may not necessarily be beneficial for the manufacturer and the overall profitability of EPSC. Additionally, the profitability of the E‐commerce platform, consumer surplus, environmental quality improvement, and social welfare are more susceptible to shifts in consumers' green perceptions, whereas increasing the eco‐label credibility is more beneficial to the revenues of the manufacturer and EPSC. From the perspective of pursuing profits, the industry label is often chosen by the manufacturer, whereas the E‐commerce platform tends to choose the government label. Whether the optimal sales mode selection strategy of the manufacturer under the eco‐label is beneficial to the E‐commerce platform also depends on the size of unit production cost, commission rate, and consumers' green perceptions (eco‐label credibility). Moreover, EPSC benefits most from the reselling mode under the industry label, whereas consumer surplus, environmental quality, and social welfare are better served by the reselling mode under the government label. Conversely, the manufacturer is more likely to decide to resell the product under the government label when the R&D for green products is highly challenging.

ABSTRACTDigital transformation has become a crucial strategic initiative to advance high‐quality development among small‐ and medium‐sized enterprises (SMEs) in developing countries. However, existing research lacks a comprehensive analysis of the complex causal mechanisms underlying successful digital transformation in SMEs. This study aims to uncover the drivers of digital transformation in SMEs and identify effective pathways for their digital adoption. Utilizing the push–pull–mooring (PPM) theory, this research applies necessary condition analysis (NCA) and fuzzy set qualitative comparative analysis (fsQCA) on a sample of SMEs to investigate the influencing factors and pathway choices for digital transformation in China. The findings indicate that digital infrastructure, technological innovation capability, digital talent, and market competitive pressure are essential conditions for advancing digital transformation in SMEs. Two primary pathways to elevate digital transformation levels in SMEs are identified: the “Fully Element‐Driven Type” and the “Push–Mooring Effects‐Oriented Type.” Comparative analysis of different pathways reveals substitution effects among certain drivers of digital transformation. This study contributes to understanding the complex causal interplay of factors influencing digital transformation in SMEs, providing actionable insights and pathway guidance for enterprises seeking to implement digital transformation.

Published: December 2024

ABSTRACTSurface‐structured mesh generation is an important part of the Computational Fluid Dynamics (CFD) preprocessing stage. The traditional method cannot automatically divide the 3D surface topology in complex structures. Thus, we propose a surface‐structured quadrilateral mesh generation method based on topology‐consistent‐preserved patch segmentation. The core idea is to segment the complex 3D model into several simple parts according to mesh quality and map each part to the 2D parametric domain based on the conformal parameterization method. Then, we utilize pattern‐based topology partitioning to divide the parametric domain into multiple quadrilateral subdomains, facilitating the generation of 2D structured quadrilateral meshes. By using the inverse mapping algorithm based on barycentric weights, the generated 2D structured mesh is inversely mapped back to the 3D space. Finally, we splice each part accurately according to the structured mesh distribution. Experimental results show that our proposed method can generate higher‐quality structured quadrilateral meshes than previous methods without losing the mesh topology of the original model.

AbstractObjectiveThis study of pregnant people with obesity examined two aims in testing the hypothesis that the COVID‐19 pandemic widened racial disparity in maternal health in high‐risk pregnancies; it compared by race both (1) gestational weight gain (GWG) patterns and (2) patterns of preexisting conditions and adverse pregnancy outcomes.MethodsThis retrospective chart review included birth certificate and delivery records from a large women's specialty hospital in Louisiana between 2018 and 2022. Differences in preexisting conditions, GWG, and adverse pregnancy outcomes were explored across early‐, peak‐, and late‐pandemic periods using log‐linear regression and robust Poisson models.ResultsAmong 7431 deliveries (54% Black), Black pregnant people had higher rates of preexisting type 2 diabetes and chronic hypertension but lower rates of gestational diabetes and preeclampsia compared to White pregnant people across all periods. Black individuals had higher prepregnancy weight and lower GWG compared to White individuals across all periods. GWG differences were not significant in peak‐ and late‐pandemic periods.ConclusionsBlack individuals with obesity started pregnancy with higher weight and more preexisting conditions but had lower GWG compared to White individuals. Exacerbated disparities in preexisting conditions demonstrate higher health risks for Black individuals during pregnancy.

ABSTRACTBackgroundKaposiform lymphangiomatosis (KLA) is a complex lymphatic anomaly associated with a somatic activating NRAS p.Q61R (NRASQ61R) mutation. KLA is characterized by malformed lymphatic vessels that can lead to effusions and coagulopathy. The goal of this study was to generate an in vivo mouse model to determine if prenatal expression of the NrasQ61R mutation in lymphatic endothelial cells induces disease characteristics found in KLA patients.ProcedureA Cre‐loxP system was used to conditionally express NrasQ61R in cells expressing lymphatic vessel endothelial hyaluronan receptor 1 (Lyve1), a marker of lymphatic and other types of endothelial cells that starts being expressed at embryonic day (E) 7.5. Because pups did not survive birth, embryos were collected at E14.5, E15.5, and E18.5 for gross analysis, histology and immunostaining, and organ whole‐mounts.ResultsStaining for NRASQ61R demonstrated robust recombination in the NrasQ61R mutant embryos and localization of NrasQ61R at sites of vascular abnormalities. NrasQ61R mutant embryos had significant edema and dysmorphic jugular lymph sacs with abnormal Lyve1‐positive cellular masses. The lymphatic vessel network in the back skin of the NrasQ61R mutant embryos had fewer branch points and increased vessel diameter. NrasQ61R mutant embryos had severe hepatic defects characterized by disordered and enlarged vessels. By E18.5, NrasQ61R mutant embryos were dead.ConclusionsConditional expression of NrasQ61R in Lyve1‐positive cells caused edema, abnormal lymphatic development, and hepatic vascular defects in mouse embryos. These findings further support the role of NRASQ61R as a driver of the lymphatic overgrowth, vessel enlargement, and dysfunction in the pathophysiology of KLA.

AbstractThe graphene electrothermal de‐icing system has attracted extensive attention due to its efficient anti‐icing/de‐icing ability, but the interlayer properties of the heating layer are relatively weak. Currently, there is limited research on the interlayer properties of multilayer complex structures of graphene papers (GPs)/glass fibers (GFs)/epoxy (EP) reinforced resin composites (GPs/GE). In this study, a GPs/GE sandwich structure was prepared using a vacuum bag molding, and the effects of fabric structure and core material on the interlaminar mechanical properties of the sandwich structure were studied using the T‐peel test. A multiscale morphological investigation was conducted to analyze the crack growth and failure modes in the sandwich structures. The results indicated that the fabric structure caused anisotropy in the interlaminar peel performance of the composite material. The weft fibers contributed to inhibiting crack propagation. The GPs/GE achieved the highest peel strength of 0.533 N/mm under the (0,90)s layup configuration. The peel performance of GPs/GE was only 5.5% lower than that of conventional metal sandwich composite materials. In addition, GPs demonstrated the advantage of being lighter and thinner within the composite material. Through co‐curing bonding, the T‐peel performance of the GPs/GE sandwich structure was improved by 72.2%, thereby solving the problem of weak interlayer properties of the heating layer.Highlights
Damage and failure mechanisms at different GPS/GE interfaces were explained.
The fabric structure resulted in anisotropy in the peel performance of GPs/GE.
The area ratio and arrangement of GPs influenced the stress distribution.
GPs/GE exhibited excellent interlayer properties after co‐curing bonding.

AbstractA critical step in the bolted connection assembly of hybrid composites is drilling. Drilling effectiveness is influenced by the interaction between the structural constitution of the composite and the type of the drilling process. The performance of traditional (TD) and abrasive water jet (AWJ) drilling of glass fiber (GF) and hybrid glass fiber/aluminum‐mesh composites with two distinct Al patterns (AGF: with Al at the surface layer and GFA: with Al in the center) has been examined, with a focus on drilling performance. Delamination (), out of roundness (), Bearing strength (), and taper angle () are the quality criteria. The experimental studies were conducted under controlled parameters for TD (feed rate, speed and point angle) and for AWJ (water pressure, stand‐off distance and traverse speed) utilizing Taguchi L9 OA. TD method produced superior performance, with decrease of 10.75%, improved by 84.26%, and increased by 20.14%. While AWJD provides minimal thermal impacts, it produces increased and more variations in hole geometry owing to its sensitivity to specimen structures and processing parameters. The outcomes provided guidance for applications in aerospace and manufacturing, indicating that optimized TD is better suited for applications requiring high hole quality, and cost‐effectiveness.Highlights
A comparative study of traditional and non‐traditional drilling processes.
AWJD produces larger , less precise, and is affected by material properties.
The TD showed compatibility for uses needing superior performance and quality.
Teacher–Student Relationship and Academic Achievement Among Adolescents: A Moderated Mediation Model
Authors: Luo Yun , Yu Xintian , Tang Yuan , Zhang Hui 
Published: December 2024

ABSTRACTThe current study investigated the mediating role of academic engagement in the association between the teacher–student relationship and academic achievement, and whether self‐control moderates the mediating process. The sample consisted of 1411 Chinese adolescents (Mage = 16.77 years, 543 boys) aged between 11 and 19 years. Self‐reported questionnaires were used to collect data. The results show that (1) the teacher–student relationship has a significant positive predictive effect on adolescents' academic achievement; (2) academic engagement has a positive mediating effect between the teacher–student relationship and academic achievement; and (3) the indirect effect of the teacher–student relationship on adolescents' academic achievement through academic engagement is moderated by self‐control, in which self‐control plays a role as a protective factor, and the indirect effect is more significant for adolescents with low self‐control than for those with high self‐control. These findings extend our understanding of how teacher–student relationships influence academic achievement among adolescents. The results have theoretical and practical value for guiding educational work in schools and improving the academic achievement of adolescents.

AbstractAntibodies and antibody mimics are extensively used in the pharmaceutical industry, where stringent safety standards are required. Implementing heat sterilization during or after the manufacturing process could help prevent contamination by viruses and bacteria. However, conventional antibodies and antibody mimics are not suitable for heat sterilization because they irreversibly denature at high temperatures. In this study, we focused on the refolding property of the cold shock protein from the hyperthermophile Thermotoga maritima (TmCSP), which denatures at elevated temperatures but regains its native structure upon re‐cooling. We designed and constructed a mutant library of TmCSP in which amino acid residues in its three surface loops were diversified. From the library, mutant TmCSPs that bind to each of eight target proteins were selected by phage and yeast surface display methods. We confirmed that the secondary structure and binding affinity of all the selected mutants were restored after heat treatment followed by cooling. Additionally, freeze‐drying did not impair their binding affinity. The crystal structure of a mutant TmCSP in complex with its target, the esterase from Alicyclobacillus acidocaldarius, revealed specific interactions between them. These results clearly demonstrate the feasibility of creating heat‐sterilizable antibody mimics using TmCSP as a scaffold.

Published: December 2024

ABSTRACTThe lack of effective treatments for dry age‐related macular degeneration (AMD) is in part due to a lack of a preclinical animal model that recapitulates features of the clinical state including macular retinal pigment epithelium (RPE) degeneration, also known as geographic atrophy (GA). A nonhuman primate model of GA was developed and its responsiveness to an approved treatment, avacincaptad pegol (ACP), a complement C5 inhibitor, was evaluated. Intravitreal (ivt) administration of sodium iodate (SI) into one eye of male Macaca fascicularis leads to retinal areas (mm2) of hyper‐ or hypo‐autofluorescence. Qualitative changes to the retinal structure over time were observed with spectral domain optical coherence tomography (OCT). Six days after SI administration, prior to treatment, mean (± SEM) GA of all eyes was 8.2 ± 1.8 mm2. Following randomization to treatment groups, either vehicle or ACP was ivt injected and treatment was continued every 4 weeks, for a total of four treatments. Sixteen weeks after SI administration, the GA area in vehicle‐treated eyes was 18.9 ± 6.6 mm2, whereas GA in ACP‐treated eyes was 11.4 ± 4.0 mm2, a reduction by about 36%. Increased, followed by decreased, overall macular thickness was observed with OCT over time following SI administration. Treatment with ACP did not change alter macular thickness thinning. Geographic atrophy‐like lesions that expand over time are observed following SI administration. The current macaque model could be utilized to further explore the mechanism of dry AMD and to develop more novel therapeutics.

AbstractBACKGROUNDCasuarina equisetifolia, a crucial species of coastal windbreaks, is highly susceptible to infestation by Anoplophora chinensis. This stem‐boring pest poses a significant threat to the health and sustainability of Casuarina equisetifolia forests. Understanding the molecular mechanisms underlying the host preference of A. chinensis to Casuarina equisetifolia is essential for developing effective pest management strategies.RESULTSThrough field surveys, we identified two cultivars of Casuarina equisetifolia that exhibited differing levels of host preference for A. chinensis. Further analysis of multi‐omics data (phenomics, transcriptomics, and metabolomics) from these cultivars revealed that longifolene plays a significant role in attracting A. chinensis to Casuarina equisetifolia. Additionally, the jasmonic acid (JA) signaling pathway was found to suppress longifolene accumulation, primarily through the interaction between the jasmonate ZIM‐domain (JAZ) proteins and the terpene synthase (TPS) gene. Moreover, we identified a critical JAZ component, CeJAZ3, whose overexpression led to the down‐regulation of TPS expression levels and, consequently, a reduced release of longifolene.CONCLUSIONWe confirmed that the negative regulator of host preference, CeJAZ3, in the JA signaling pathway can suppress the expression of TPSs, thereby down‐regulating the accumulation of longifolene in Casuarina equisetifolia and indirectly suppressing the attraction of host plants to A. chinensis, which provides a basis for the integrated management of A. chinensis. © 2024 Society of Chemical Industry.

Published: December 2024

AbstractIn recent years there has been an advance towards coupled Earth‐system models for weather forecasting. For example, the European Centre for Medium‐Range Weather Forecasts now implements ocean–ice coupling with dynamic sea ice in the Integrated Forecasting System (IFS) at all time ranges. This has the potential to improve weather forecasts in the polar regions, where sea ice influences the overlying atmosphere directly by turbulent exchange, especially in the rapidly warming summer‐time Arctic where thinner and more mobile ice is susceptible to rapid change. In this study, we investigate the sensitivity of IFS (cycle 47r1) weather forecasts to sea‐ice coupling representation in the summer‐time Arctic by comparing three sets of forecasts that are coupled with (i) dynamic sea ice in operational configuration, (ii) static sea ice, and (iii) dynamic sea ice with additional thermodynamic (surface temperature and albedo) coupling. It is found that dynamic sea ice improves predictions of sea ice and the ice edge compared with persistence, especially in the vicinity of Arctic cyclones. The dynamic sea‐ice forecasts exhibit lower near‐surface temperatures (up to 0.5 °C) compared with static sea‐ice forecasts where ice loss has occurred, and differences in near‐surface winds of up to 0.5 , consistent with changing surface roughness over the marginal ice zone. The forecasts with additional thermodynamic coupling have near‐surface temperatures that are up to 1 °C cooler over ice than the operational configuration (correcting a known warm bias), consistent with a more stable boundary layer (BL) and weaker near‐surface winds. The influence of sea‐ice coupling above the BL is small, with differences in cyclone forecasts being smaller than the spread of the operational ensemble. This study highlights the influence of ocean–ice coupling in weather forecasts for the summer‐time Arctic, and the potential gains from improving its representation.

Published: December 2024

AbstractResearch SummaryWe investigate family CEO birth order as an antecedent of family firms' CSR behavior. Despite psychology literature recognizing it as a key predictor of individual behavior, birth order has been largely neglected in management research. Drawing on behavioral economics and evolutionary psychology—specifically, the Family Niche Model—we identify economic and social preferences as two competing channels through which birth order effects propagate to CSR behavior. An unbalanced panel dataset of 550 firm‐year observations from 84 family firms between 2010 and 2022 reveals a negative relationship between family CEO birth order and CSR behavior, pointing to the dominance of the economic channel, whereby the higher risk tolerance among later borns manifests. This relationship is positively and negatively moderated by family CEO sibship size and age, respectively.Managerial SummaryWe examine the role of family CEO birth order in shaping family firms' CSR behavior considering that individuals' economic and social preferences are strongly influenced by their birth order. The results show that family CEO birth order negatively relates to CSR behavior. We argue that this relationship is driven by higher risk tolerance among later‐born family CEOs, who are consequentially less inclined to adopt CSR behavior as a risk‐mitigating strategy. The relationship is attenuated by family CEO sibship size and amplified by CEO age. Our study cautions family firms concerned with CSR to carefully consider the implications of birth order when selecting family members for the CEO position. Concurrently, family CEOs should be aware that their early family experiences may affect their CSR decisions.
