Moreover, consumer loss aversion (CLA) is pronounced when buying from SBEs that have yet to develop a strong reputation and uncertain quality. We focus on two competing SBEs with heterogeneous quality levels and discuss their quality disclosure strategies— whether selling through a retailer— in the context of CLA. We study the interaction between consumers' prior belief in product quality and CLA and how these factors affect equilibrium outcomes. We show that a situation in which low-quality and high-quality SBEs both choose to disclose will not occur under a neutral consumer attitude, i.e., it happens only when the aversion level is significant. When the aversion level is low, either the low-quality SBE or the high-quality SBE will decide to disclose, and the disclosing party depends on the prior belief. In addition, CLA significantly impacts the monotonicity of both SBEs' and retailers' prices and profits relating to the consumers' prior beliefs.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"9 1","pages":"Pages 62-87"},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096232023000598/pdfft?md5=0184bde182f38b11ae13fc505042bbe5&pid=1-s2.0-S2096232023000598-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139493580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It analyzes survey data collected from 206 Chinese manufacturers. The results show that the three SCR dimensions are positively related to customer satisfaction, whereas customer resilience has no direct contribution to financial performance. Internal resilience moderates the relationship between supplier resilience and performance (negative for customer satisfaction and positive for financial performance). A taxonomy for SCR was developed based on internal, supplier, and customer resilience, providing a holistic perspective for examining the performance discrepancies among four different SCR patterns: high external-leaning, high uniform, medium uniform, and low uniform.

However, studies on the implementation of this policy proposition are limited. To address this gap in the literature, this study employs machine learning techniques, specifically natural language processing (NLP), to examine 77 climate bond (CB) policies from 32 countries within the context of climate financing. The findings indicate that “sustainability” and “carbon emissions control” are the most outlined policy objectives in these CB policies. Additionally, the study highlights that most CB funds are invested toward energy projects (i.e., renewable, clean, and efficient initiatives). However, there has been a notable shift in the allocation of CB funds from climate-friendly energy projects to the construction sector between 2015 and 2019. This shift raises concerns about the potential redirection of funds from climate-focused investments to the real estate industry, potentially leading to the greenwashing of climate funds. Furthermore, policy sentiment analysis revealed that a minority of policies hold skeptical views on climate change, which may negatively influence climate actions. Thus, the findings highlight that the effective implementation of CB policies depends on policy goals, objectives, and sentiments. Finally, this study contributes to the literature by employing NLP techniques to understand policy sentiments in climate financing.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"9 1","pages":"Pages 1-15"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096232023000495/pdfft?md5=80323415753fbddb130d3f65a60bcf20&pid=1-s2.0-S2096232023000495-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135614114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the issue that most conventional pedestrian grouping models (PGMs) can only identify a pedestrian group at a limited distance of less than 2 m, this study extended the pedestrian distance constraint of conventional PGMs with a reconstruction of the normal group detection criterion and development of a novel group detection criterion suitable for long-span space. To measure the movement behavior similarity with normal distance, five necessary constraints: velocity difference, moving direction offset, distance limitation, distance fluctuation, and group-keeping duration were studied quantitatively to form the criterion to detect normal groups. Meanwhile, a long-span group detection criterion was proposed with extended distance and direction consistency constraints. Therefore, this study proposed an improved PGM that considers long-span spaces (PGMLS). In the PGMLS workflow, the MMTrack algorithm was used to obtain pedestrian trajectories. A difference measurement method based on sequential pattern analysis (SPA) was adopted to analyze the velocity similarity of pedestrians. To validate the proposed grouping model, experiments based on pedestrian movement videos in the exit hall of the Shanghai Hongqiao International Airport were conducted. The results indicate that the proposed model can detect both normal and widely separated pedestrian groups, with a long span range of 2–12 m.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"8 3","pages":"Pages 398-412"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43092744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the scale of additional tariffs increased, the volatility of the Chinese soybean futures market declined; however, the volatility of the US soybean futures market did not weaken. In addition, expanding the sources of soybean imports helped ease the impact of tariffs on China’s soybean futures market, while the decline in US soybean exports to China intensified the volatility of the US soybean futures market.

We also consider two qualitative indicators of online loan background, namely platform background and guarantee mode, that reflect Chinese characteristics. Subsequently, a factor analysis was conducted to reduce the 14 indicators’ dimensions. The loads of the rating indicators in the resulting rotating component matrix were refined into an OLP operation scale factor, fund dispersion factor, security factor, and profitability factor. Finally, a K-means clustering algorithm was employed to cluster the factor scores of each OLP, thereby obtaining credit rating results.
