Is corporate governance a significant factor in corporate social responsibility disclosure? Insights from China

This comprehensive study delves into the intricate relationship between corporate governance and Corporate Social Responsibility Disclosure (CSRD) within the framework of China’s institutional landscape. By analyzing an extensive dataset comprising 35,435 firm-year observations from 3,889 A-share listed companies spanning the years 2006 to 2019, the research scrutinizes various governance mechanisms, including board size, independence, CEO duality, and ownership concentration.The investigation affirms that larger boards and a higher proportion of independent directors exert a positive influence on CSRD. In contrast, a substantial shareholding ratio held by the largest shareholder proves to be a hindrance to the transparent disclosure of CSR initiatives. While the impact of CEO duality on CSRD is noted, the statistical significance of this relationship remains inconclusive.These findings underscore the nuanced dynamics of governance and ownership structures in shaping CSR initiatives. The findings highlight the nuanced impact of governance and ownership structures on CSR initiatives, offering valuable insights for managers and policymakers navigating CSR strategies in China’s business landscape. The insights garnered from this study hold valuable implications for both corporate managers and policymakers navigating the landscape of CSR strategies within the unique contours of China’s business environment.

Study of the efficiency of sweet potato growing in the Forest-Steppe of Ukraine by different methods of soil mulching

Sweet potato (Ipomoea batatas L.) is a new crop for soil and climatic conditions of Ukraine, the active implementation of which is hindered by the lack of recommendations on technological aspects of cultivation. One of the important technological measures for growing sweet potatoes is the use of soil mulching, which improves the water regime and regulates the thermal regime of the soil; prevention of weed growth and growth of sweet potato shoots to the soil. Thus, the aim of the research is to determine the efficiency of growing sweet potatoes in the Forest-Steppe of Ukraine by different methods of soil mulching. Field research was carried out on typical low-humus light loamy chernozem on loess loam. It was noted, that when growing sweet potatoes on ridges, the introduction of mulching the soil with black polyethylene film provides more active growth of the vegetative mass throughout the growing season (5.33 shoots/plant with a total length of 252.1 cm), while growing without ridges has a positive effect on plants growth due to the general absence of mulch (2.53 shoots/plant with a total length of 107.8 cm). The use of ridges and mulching the soil with black polyethylene film causes the yield of sweet potato tubers at 34.8 t/ha, while the mulching of the soil with straw, the yield was 18.3–21.9 t/ha, without mulching – 13.0–17, 1 t/ha. Mulching with black polyethylene film ensures the accumulation of vitamin C and starch in sweet potato tubers. When growing the culture on ridges by this method of mulching, the maximum level of vitamin C according to the experiment (4.78 mg/100 g) and starch (11.73 %) was noted. The introduction of mulching and ridge formation involves additional material and labor costs, but helps to reduce weed control and tuber digging costs. When growing sweet potatoes on ridges with mulching with black polyethylene film, the minimum additional labor costs for the formation of a unit of yield (1.95 man-minutes/kg of tubers) were noted, while without mulching and without ridges this figure was 6.76 man-minute/kgSweet potato (Ipomoea batatas L.) is a new crop for soil and climatic conditions of Ukraine, the active implementation of which is hindered by the lack of recommendations on technological aspects of cultivation.

Reviewing challenges in the application of eddy current arrays and their impact on NDT efficiency

Eddy current arrays (ECAs) have gained significant popularity in the field of non-destructive testing (NDT) due to their ability to provide fast and accurate inspection results. However, several challenges associated with using ECAs in NDT need to be overcome in order to improve inspection performance. One of the primary challenges with ECAs is the impact of array size and geometry on inspection effectiveness. The size and shape of the ECA directly influence the sensitivity and resolution of the inspection process, making it challenging to optimize these parameters for specific inspection scenarios. Furthermore, the use of large ECAs can lead to increased noise levels and reduced inspection speed, negatively affecting the overall efficiency of the inspection process

Research of garlic preservation depending on treatment with hydrophobic protective coatings and growth-inhibiting substances

The aim of the work was to improve the elements of garlic bulb storage technology by using hydrophobic protective coatings, growth inhibitors. The study allows you to choose protective coatings of garlic bulbs for long-term storage and extend the duration of storage.It has been found, that the loss of weight of garlic bulbs during storage depends on the method of storage and type of treatment of garlic plants. Weight loss during storage in boxes with polyethylene inserts is reduced by 2 times, bulbs, treated with paraffin, – by 3.4 times. Treatment of plants with maleic acid hydrazide (MAH) reduces weight loss by 1.7 times. After 6 months of storage, the loss due to dry matter ranged from 51.7 to 69.7 % of weight loss.It has been found, that the treatment of plants by MAH helps to reduce losses due to germination of bulbs, damage by microorganisms, drying compared to the control version and storage in boxes with polyethylene inserts. The highest yield of 91.8 % of commercial bulbs is provided by their treatment with paraffin. Analysis of variance showed that the method of storage affects the preservation of garlic by 98 %, the development of diseases – by 54 %. Treatment by MAH affected the germination of bulbs by 98 %. Based on the obtained results, a correlation analysis was performed and the linear dependence of the weight loss of winter garlic bulbs depending on the peculiarities of the storage method was establishe
