    Abstract Abstract This article is one of the first attempts to materialise Joanna Haynes and Karin Murris’ conceptualisation of the post-age pedagogy that focuses on loosening the boundaries of age-based expectation. The project is conducted against the backdrop of the discourse of ageism existing hand-in-hand with various age-transgressive practices. It involved multiple case studies of child and adult readers’ responses to two picturebooks, i.e., How to Five Forever (1995) and Grandpa Green (2011). The two research questions are: how do children and adults respond to Forever and Grandpa? What is the pattern of similarities and differences in their responses? In addressing these research questions, the present study aims to facilitate the emergence of a post-age picturebook pedagogy. The findings reveal that a post-age picturebook pedagogy should acknowledge the chance of holistic learning opportunities that picturebooks can offer to both children and adults, including, for instance, aesthetic appreciation, literary understanding, emotional engagement, and material experience. Such a pedagogy involves an egalitarian view of child and adult that acknowledges some biologically determined differences subject to the factor of age and meanwhile emphasises their shared humanity and idiosyncrasies, thus undermining the binary division between simple child and sophisticated adult. The material affordances of a picturebook can be deployed to amplify the points of connection and dialogue in child and adult readers’ responses and a post-age picturebook pedagogy should strive to enrich interpretive and experiential possibilities for diverse readerships. In comparison with the existing empirical studies using picturebooks, this project positions adults as readers who can enjoy picturebooks for their own sake rather than co-readers whose responsibility is mainly to facilitate child readers’ learning and development. It stresses and seeks to maximise the potential of picturebooks for creating a beneficial and pleasant experience for ...

    Abstract In the Yangtze River Delta region, where the agricultural economy is well developed and agricultural pollution and carbon emissions are significant, a regional study of AEE (Agricultural Eco-Efficiency) is crucial to reducing agricultural environmental pollution, improving the rationalization of agricultural production layout, and promoting the realization of low-carbon goals. The SBM-Tobit model and GIS were employed to analyze AEE based on the carbon emission evaluation system in the spatial and temporal characteristics, as well as the influencing factors and the migration path of the center of gravity in the “low carbon” context. A rational plan of agricultural production was proposed according to the results. The following results were obtained: (1) The level of AEE in the Yangtze River Delta region was high, and the region exhibited a U-shaped curve change from 2000 to 2020, with a fluctuating decrease from 2000 to 2003 and a fluctuating increase from 2004 to 2020. The regional spatial development balance was enhanced, while there was a spatial incongruity in the development process of AEE enhancement, high in the southwest and low in the northeast; (2) AEE generally had a high regionalized agglomeration of low–low in the southwest and high–high in the northeast. Nonetheless, temporal heterogeneity was observed in spatial correlation, and the correlation weakened with time variation; (3) Urbanization level, agricultural production structure, crop cultivation structure, and fertilizer application intensity were the main factors influencing AEE in the Yangtze River Delta region; (4) The center of gravity of AEE in the Yangtze River Delta region shifted to the southwest under the influence of “low-carbon” related policies. Therefore, the improvement of AEE in the Yangtze River Delta region should focus on inter-regional coordination and linkages, rational planning of production factors, and the formulation of measures under relevant carbon policies.

    Abstract China’s listed companies have serious Principal-agent problem of the second kind. Large shareholders have violated the rights and interests of minority shareholders in an endless stream of cases. However, the voice of encouraging minority shareholders to actively participate in enterprise decision-making is growing day-by-day. However, there is no consensus on whether the enthusiasm of minority shareholders in decision-making can have a positive impact on enterprises. Therefore, this article takes China’s A-share listed companies from 2016 to 2020 as the research sample, and from the perspective of green innovation, discusses whether the minority shareholders’ active participation in enterprise decision-making can improve the level of green innovation of enterprises. The study found that the minority shareholders’ active participation in enterprise decision-making can improve the level of green innovation. Moreover, the minority shareholders’ “hand voting” improves the green innovation level of enterprises by influencing the media attention; A higher level of legal environment is conducive to strengthening the role of minority shareholders’ participation in the shareholders’ meeting in green innovation. Based on the property right nature, regional and industrial level, further research found that the minority share-holders’ role in improving green innovation capacity is more significant in non-state-owned enterprises, eastern regions and heavy pollution industries. The research results show that minority shareholders, as an important force to monitor the senior executives’ behavior and enhance corporate value, actively participate in corporate decision-making, can not only improve corporate governance, but also benefit the sustainable development of enterprises.

    Abstract Mixed ownership reform has contributed greatly to China’s economic development; however, there is little literature on how mixed ownership reform affects carbon performance in the context of environmentally sustainable development. Therefore, this paper takes A-share industrial state-owned enterprises in Shanghai and Shenzhen from 2008 to 2020 as research samples to investigate the impact of mixed ownership reform on carbon performance through empirical tests. The results show that the mixed ownership reform of state-owned enterprises can improve the carbon performance of enterprises. The intermediary test shows that green innovation plays an intermediary role in the relationship between mixed ownership reform and carbon performance. Furthermore, compared with green management innovation, mixed ownership reform has a stronger promoting effect on green technology innovation, and green technology innovation has a greater impact on carbon performance. Heterogeneity analysis shows that in heavily polluted industries and competitive industries, mixed ownership reform of state-owned enterprises has a more significant role in improving carbon performance. Therefore, the mixed ownership reform of state-owned enterprises is of great significance for promoting environmental sustainable development. Overall, this study provides empirical evidence for the environmental sustainable development of state-owned enterprises in emerging markets.

    Abstract Coastal aquaculture is undertaken in shallow and usually sheltered waters along the coast, delineated by aquaculture ponds. Illegal usage of coastal aquaculture can lead to conflicts with local communities and environmental problems. Thus, it is necessary to extract the aquaculture boundary to monitor the expansion of coastal aquaculture to the sea. However, it is challenging for most existing algorithms to extract the aquaculture boundary for synthetic aperture radar (SAR) images under a high incident angle (>30 degree) with horizontal transmitted and received (HH) or vertical transmitted and received (VV) polarization. The difficulties come from the following: (1) seawater can be seen on both sides of such boundaries, (2) the contrast of such boundaries is uneven, and (3) the backscattering coefficients in some parts of such boundaries are low. In this paper, a novel dual-link weight random walk (DLRW)-based method is proposed to extract such boundaries. The proposed DLRW is composed of an automatic seed points generation strategy, and the establishment and solving of a random walk model with the dual-link weight. By a coarse-to-fine procedure, DLRW is used to extract the aquaculture boundaries in the whole imagery. Sentinel-1 and GF-3 images in Dalian and Liaodong Bay, China have been used in experiments. Mean offset (MO), root mean square error (RMSE), Overlapped, accuracy within one pixel (WOP), and accuracy within two pixels (WTP) have been used to evaluate the performance with existing methods. Experimental results have demonstrated the proposed DLRW-based method outperforms existing methods in the extraction on aquaculture boundaries. Under the low tide, the DLRW-based method is better than the other two methods with MO, RMSE, Overlapped, WOP, and WTP by at least 5.75 pixels, 10.43 pixels, 2.88%, 11.09%, and 18.04%, respectively. Under the high tide, the DLRW-based method is superior to the other two methods with MO, RMSE, and WTP by at least 3.8 pixels, 10.5 pixels, and 6.3%. In addition, the ...

    Abstract Saltpans extraction is vital for coastal resource utilization and production management. However, it is challenging to extract saltpans, even by visual inspection, because of their spatial and spectral similarities with aquaculture ponds. Saltpans are composed of crystallization and evaporation ponds. From the whole images, existing saltpans extraction algorithms could only extract part of the saltpans, i.e., crystallization ponds. Meanwhile, evaporation ponds could not be efficiently extracted by only spectral analysis, causing the degeneration of saltpans extraction. In addition, manual intervention was required. Thus, it is essential to study the automatic saltpans extraction algorithm of the whole image. As to the abovementioned problems, this paper proposed a novel method with an amendatory saltpan index (ASI) and local spatial parallel similarity (ASI-LSPS) for extracting coastal saltpans. To highlight saltpans and aquaculture ponds in coastal water, the Hessian matrix has been exploited. Then, a new amendatory saltpans index (ASI) is proposed to extract crystallization ponds to reduce the negative influence of turbid water and dams. Finally, a new local parallel similarity criterion is proposed to extract evaporation ponds. The Landsat-8 OLI images of Tianjin and Dongying, China, have been used in experiments. Experiments have shown that ASI can reach at least 70% in intersection over union (IOU) and 78% in Kappa for extraction of crystallization in saltpans. Moreover, experiments also demonstrate that ASI-LSPS can reach at least 82% in IOU and 89% in Kappa on saltpans extraction, at least 13% and 17% better than comparing algorithms in IOU and Kappa, respectively. Furthermore, the ASI-LSPS algorithm has the advantage of automaticity in the whole imagery. Thus, this study can provide help in coastal saltpans management and scientific utilization of coastal resources.

    Abstract Abstract To study whether hydroxychloroquine (HCQ) therapy increases the risks of cataracts in patients with rheumatoid arthritis (RA). In this retrospective cohort study, 2821 treatment-naive RA patients, collected from the Longitudinal Health Insurance Database, were enrolled from 2000 to 2012 and followed up monthly until secondary cataracts were detected but no later than Dec 31, 2013. All participants were split into two groups according to the usage of HCQ in one year: the HCQ group (465 patients), with a usage duration higher than 90 days, and the non-HCQ group (465 patients), with a usage duration less than 30 days. The HCQ and non-HCQ groups were age-, sex-, complication- and drug combination-matched. There was no significant difference in survival rate between the two groups (p > 0.05). A multivariate logistic regression model was applied. Of all participants, 173 were diagnosed with secondary cataracts in both the HCQ and non-HCQ groups, with 28.8/1000 and 36.5/1000 person-years, respectively. After adjustments for other predictors, patients in the HCQ group had no increased (or decreased/equal) hazard of secondary cataract (hazard ratio (HR): 1.17; confidence interval (CI): 0.86–1.59; p > 0.05). HR analysis of HCQ usage duration, age, sex and corticosteroids showed that the CI of the adjusted HR was not statistically significant. This study showed that HCQ usage was not associated with the risk of cataracts in RA patients.

    Abstract True morels ( Morchella , Pezizales) are a popular edible and medicinal fungus with great nutritional and economic value. The dynamics and regulatory mechanisms during the morphogenesis and maturation of morels are poorly understood. In this study, the metabolomes and transcriptomes of the mycelium (MY), primordium differentiation (PR), young fruiting body (YFB), and mature fruiting body (MFB) were comprehensively analyzed to reveal the mechanism of the morphogenesis and maturation of Morchella sextelata . A total of 748 differentially expressed metabolites (DEMs) and 5342 differentially expressed genes (DEGs) were detected, mainly enriched in the carbohydrate, amino acid, and lipid metabolism pathways, with the transition from the mycelium to the primordium being the most drastic stage at both the metabolic and transcriptional levels. The integrated metabolomics and transcriptomics highlighted significant correlations between the DEMs and DEGs, and specific amino acid and nucleotide metabolic pathways were significantly co-enriched, which may play key roles in morphological development and ascocarp maturation. A conceptual model of transcriptional and metabolic regulation was proposed during morphogenesis and maturation in M. sextelata for the first time, in which environmental factors activate the regulation of transcription factors, which then promote metabolic and transcriptional regulation from vegetative to reproductive growth. These results provide insights into the metabolic dynamics and transcriptional regulation during the morphogenesis and maturation of morels and valuable resources for future breeding enhancement and sustainable artificial cultivation.

    Abstract Personal factors such as the founder's values and psychological characteristics will influence founder's vision, his perception and interpretation of the decision-making environment, and his strategic choice and decision-making. Based on the theory of entrepreneurial characteristics, combined with the founder's unique psychological characteristics, this paper takes Chinese private listed companies between 2010 and 2018 as a research sample to study the effect of the founder of private enterprises on corporate social responsibility. Furthermore, this study analyzes the impact of different management roles of the founder on corporate social responsibility. We demonstrate that the private enterprises have better social responsibility performance when there are founders; the founders have different management roles, and their corporate social responsibility performance has certain differences, and the higher the management level of the founders, the better the corporate social responsibility performance. This paper studies the issue of corporate social responsibility from the perspective of the characteristics of founders, which expands the current framework of corporate social responsibility research and provides an empirical basis for founders to effectively participate in corporate management in practice.

    Abstract In wireless multi-hop networks, such as wireless sensor networks, link quality (LQ) is one of the most important metrics and is widely used in higher-layer applications such as routing protocols. An accurate link quality prediction may greatly help to improve the performance of wireless multi-hop networks. Researchers have proposed a lot of link quality prediction models in recent years. However, due to the dynamic and stochastic nature of wireless transmission, the performance of link quality prediction remains challenging. In this article, we mainly analyze the influence of the stochastic nature of wireless transmission on the link quality prediction model and discuss the benefits in the application of wireless multi-hop networks with the performance-limited link quality prediction models.
