ICT-DCU question answering task at NTCIR-6
No full textThis paper describes details of our participation in the
NTCIR-6 Chinese-to-Chinese Question Answering task. We
use the “retrieval plus extraction approach” to get answers
for questions. We first split the documents into short passages, and then retrieve potentially relevant passages for a question, and finally extract named entity answers from the most relevant passages. For question type identification, we use simple heuristic rules which cover most questions. The Lemur toolkit was used with the okapi model for document retrieval. Results of our task submission are given and some preliminary conclusions drawn
Sustainable infrastructure, energy projects, and economic growth: mediating role of sustainable supply chain management
No full textEconomic integration and infrastructure connectivity among countries has garnered significant interest due to its immense scale and potential political and economic impact. Special economic zones (SEZ), energy projects, and sustainable infrastructure are influential catalysts that have the potential to boost economic stability and promote growth through the execution of sustainable supply chain management (SSCM) practices and adoption of a friendly approach to glocalization. However, literature on Supply Chain Management has provided limited coverage on this phenomenon. This research investigates the potential of SEZs, energy projects, sustainable infrastructure as key drivers for building economic resilience. It also examines the mediating role of SSCM and glocalization. Data was gathered from participants who were knowledgeable about the economic landscape and engaged in activities related to SEZs, sustainable infrastructure, and energy projects through a questionnaire. The study employed structural equation modeling (SEM) technique to investigate the hypothesis and examine the mediating role. The study findings indicate that SEZ establishments foster economic resilience by attracting foreign investment, promoting industrial diversification, and facilitating technology transfer. Energy projects, including development of renewable energy sources and energy infrastructure, enhance energy security and mitigate potential risks associated with energy scarcity. Through effective supply chain management, responsible sourcing, green logistics, and waste reduction, economic resilience can be bolstered. Also, glocalization, which seeks to reconcile global and local viewpoints, plays a vital role in ensuring economic stability. The present research thus enhances academic comprehension of the intricate interactions between energy projects, sustainable infrastructure, sustainable supply chain management, and economic growth

Influence of sulfonic acid group on the performance of castor oil acid based methyl ester ethoxylate sulfonate
No full textCastor oil acid methyl ester ethoxylate sulfonate (CAMEES) is a new multifunctional anionic-nonionic surfactant with three hydrophilic groups. In this work, CAMEES was synthesized through reaction of castor oil acid methyl ester ethoxylate (CAMEE) with sodium bisulfite in the presence of tert-butyl peroxybenzoate as catalyst and ferric chloride as co-catalyst in solution of water and isopropanol. The sulfonic acid group has an important effect on the physicochemical properties of the surfactant. Compared to CAMEE, CAMEES exhibits better soybean oil emulsification, detergency, foam ability and stability. However, owing to the sulfonic acid group, the wetting ability and paraffin emulsification are more limited

Synthesis and properties of α-sulfo carboxyl disodium salt
No full textThe synthesis and properties of α-sulfo carboxyl disodium salt (SCDS) were studied in detail for the first time in this paper. SCDS was synthesized via saponification reaction of fatty acid methyl ester sulfonate sodium (MES). FT-IR was used to characterize the molecular structure of target product. The yield of disodium salt was greater than 98% by two-phase titration. The performance of SCDS was studied and was compared with raw materials MES, conventional anionic surfactant AES and nonionic surfactant AEO9. The result shows SCDS can reduce the surface tension of the solution to 27.89 mN/m at critical micelle concentration (CMC). The wetting ability of SCDS was significantly enhanced with the increase of temperature. The emulsification effect of SCDS on the soybean oil is better than that on the liquid paraffin. Surprisingly, SCDS has a good foamability and foaming stability

Multinational companies’ coordination mechanism for extending corporate social responsibility to Chinese suppliers
No full textFrom the global supply chain perspective, this research explores how multinational companies (MNCs) can extend corporate social responsibility (CSR) practices to emerging countries such as China. A two-stage supply chain game model consisting of a Chinese supplier and a MNC is constructed. The study finds that an increase in the level of the Chinese supplier's CSR increases the product demand and the stakeholders' economic profits, but reduces the supplier's economic return; the product demand and the stakeholders' benefits increase along with the product green degree improvement, but the changes in the Chinese supplier's economic profits are jointly affected by the level of CSR and green production efficiency. The supply chain coordination can be achieved based on a revenue sharing contract. Finally, the effects of revenue sharing fraction and supplier's CRS level on product green degree, supplier's revenue and MNC's earnings are discussed by numerical simulation
Responsibility disengagement or sharing? Cooperative fulfilling mechanism of solid waste management in the remanufacturing supply chain
No full textDue to limited resources and meager profits, collectors have insufficient motivation to fulfill their responsibilities, resulting in severe secondary pollution in the recycling process. Therefore, it is necessary to focus on the interests of collectors to motivate them to fulfill their solid waste management (SWM) responsibilities better. This paper focuses on remanufacturers’ altruistic behavior in the context of collectors’ compliance. Based on the Stackelberg game method, this paper constructs decision-making models for remanufacturers concerned or not concerned about the interests of collectors and compares the optimal decision-making outcomes of each model. The study finds that (1) based on remanufacturers’ altruistic concerns, a coordination mechanism for sharing responsibility-fulfilling costs for collectors can motivate them to fulfill their responsibilities and improve the performance of the remanufacturing supply chain. (2) The proportion of the remanufacturer’s share of the responsibility cost for the collector should not be too low, which is not conducive to encouraging the collector to fulfill the responsibility. However, the sharing proportion should not be too high, as this will increase the burden on the remanufacturer. This paper demonstrates the applicability of remanufacturers to moderately share responsibility costs for collectors to incentivize collectors to fulfill their responsibilities. The findings bridge the gap in research on SWM in remanufacturing supply chains. The management insights from this paper are expected to help remanufacturing supply chain companies establish a reuse behavior model that addresses the challenges that SWM faces to improve remanufacturing supply chain performance
