The primary goal is to support aid organizations in planning the delivery of essential aid services during migration movements, offering insights that can be applied to various geographical areas and migration scenarios. While we use the Syrian refugee movement to Turkey as a case study, the model is intended as a flexible tool for analyzing migration patterns in future crises. The proposed ABM considers two characteristics of refugee groups: level of risk sensitivity and level of information. To enhance the model’s functionality, we have extended the A* algorithm with a cost metric to calculate the weighted average of distance and risk to a destination point. Our case study examines the crisis in southern Idlib through six scenarios, offering insights into refugee numbers, migration paths, camp occupancy rates, and heat maps of densely populated regions for each scenario. Validation is performed by comparing model outcomes with situation reports and official statements from the relevant period, demonstrating the proposed ABM’s potential for adaptation to other migration instances and further analysis under different parameters.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"96 ","pages":"Article 102089"},"PeriodicalIF":6.2,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142536124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper explores the influence of AI on EIE, with a focus on the role of accounting information transparency. Using data from Shanghai and Shenzhen A-share listed enterprises between 2010 and 2021, the findings demonstrate that AI development significantly enhances EIE. These results are confirmed through robustness tests, including variable substitution, and addressing endogeneity and sample limitations. Mechanism analysis reveals that AI improves EIE by increasing the transparency of accounting information. Additionally, heterogeneity analysis shows that AI has a greater impact on the investment efficiency of high-tech and technology-intensive enterprises, non-state-owned enterprises, and those located in highly urbanised areas, such as ‘Broadband China’ pilot cities.

Moreover, there was heterogeneity in the policy’s effects, with the implementation of a LCTS being more effective in eastern and central regions of China and in larger and more compact cities.

This situation puts food trade, which is resources constrained and susceptible to political relations, into a complex dilemma. Due to the concerns on agricultural endowments, food trade needs to be considered with strategic interests because of its sensitivity and fragility. Using virtual land as a measurement to analyse the resource flows behind the food trade can provide an objective perspective on what extent a country depends on the trade. Overlaying worldwide trade disputes and political interventions, establishing solid trade relationships is increasingly becoming urgent. This study uses an extended gravity model, assesses the virtual land traded by China with 10 species over 20 years, and provides insights on establishing politics-oriented trade relationships, further testing how this political mechanism works in the food trade. The results demonstrate that memorandums of understanding are the fundamental institutional layer to guarantee trading activities and promote smooth transactions for both sides; state visits are determinable factors in establishing bilateral relationships and it significantly promote upper-middle income countries, which crucially impacts the trading system. As those endeavors undertaken by executive departments are often ignored, more attention should be paid to them during interactive stages. Political relations show differences in food trade among different countries and varieties. The promoting effect of political relations is stronger in middle and high-income countries, and the impact on Russia and Ukraine is more significant than others. Compared within varieties, foreign state visits and endeavor presents more positive on pork.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"96 ","pages":"Article 102085"},"PeriodicalIF":6.2,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142418684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, therefore aims to identify and analyze the degree of significance of the challenges to SC resilience in Nigerian retail firms under disruptions, as well as propose strategies to mitigate them for enhancing retail SC resilience under potential disruption risks in the post COVID-19 era.

Then, a methodology based on integrating decision-making trial and evaluation laboratory with the Shannon entropy concept and simple additive weighting was proposed to aid in the study analysis. Results indicate that the operational-level context is most significant and ranks highest in deterring SC resilience in Nigerian retail firms under disruptions. Specifically, 'limited credit facility' is the highest ranked challenge, followed by 'lack of Omni channel fulfilment capabilities', 'delivery irregularities', ‘workers’ high welfare package’ and 'lack of supplier collaboration’. Besides, 'incentivisation' mitigates these challenges the most and is strongest linked to build retail SC resilience, followed by 'digitalization' and ‘SC localisation'.

In this research, modeling methods used for legal supply chains are adapted to spatially disaggregate illicit supply chain flows. Profit and supply maximization model versions were compared to elucidate key decision parameters cocaine traffickers might be facing. Cocaine flows to EU+3 (Norway, Turkey, and United Kingdom) markets were estimated based on the smuggling capacity of major Central American ports and bilateral trade volumes of selected commodities most often seized with cocaine shipments. The resulting estimates of cocaine volumes diverted to EU+3 countries from Central America ranged between 938 and 1526 metric tons (MT). Generally, easier concealment and storage in Central America led to less volume supplied to the United States (US) and increased shipments to EU+3 markets.

The region is currently home to 123 active terrorist/insurgent groups and is accountable for over 27 % of recorded global terrorist attacks. The annual data from the six most-terror-affected South Asian countries (Afghanistan, Bangladesh, India, Nepal, Pakistan, and Sri Lanka) during the US-led war on terror (2001 - 2022) is used. For econometric estimation, the five models: fixed-effect, generalized least squares (GLS), generalized estimating equation (GEE), quantile regression (QR), and panel-corrected standard errors (PCSE) are applied. Terror-related death (a proxy for human capital loss) and per capita income (a proxy for purchasing power) are considered to measure terrorism and its economic impact. In addition, four economic indicators (military expenditure, population, official development assistance (ODA), and USAID) and three institutional indicators (electoral democracy index, political violence index, and mobilization for autocracy index) are taken into account as control variables. The result suggests that every additional 886 terror-related human capital loss across the region significantly reduces the purchasing power of each South Asian person by at least 9.800 US dollars. Moreover, among the control variables, military expenditure, political violence, and mobilization for autocracy negatively affect per capita income, while electoral democracy, population, ODA, and USAID positively impact it.
