Sponsored content policy enables a provider to pay network operator, and thereby their users access contents from the through services operator with lower charge. In this paper, we study interaction among three entities under sponsored policy, namely, or service provider, end-users. We consider hierarchical three-stage setting formulate game theoretic model analyze interaction. Using model, derive user demand, optimal sponsoring of pricing based on backward induction. The incorporates...

This study investigates lid-driven cavity flows at high Reynolds numbers (Re = 1 × 105–1 106) using particle image velocimetry. The results reveal significant changes in vortex dynamics, including the expansion and increased intensity of primary vortex, suppression secondary regions, thinning boundary layer. As number increases, impact walls becomes more pronounced, leading to smaller vortices near enhanced energy dissipation, accompanied by a gradual decrease flow velocity. A proper...

Citizen involvement in major government initiatives is increasingly favoured the evolving theory and practice of public administration. As a mega project, Shanghai Expo featured citizen both as publicity idea pragmatic approach for obtaining resources support from citizens. Due to lack participatory democratic tradition, municipality has sought promote through specific social projects over short time.

Achieving carbon neutrality depends on emission reduction and sequestration. However, research vegetative sequestration in China remains preliminary. In this study, we calculated the total of terrestrial vegetation that different types from 2001–2019 using satellite data. Total slowly increased but its increase was significantly lower than emissions over same period. Provinces with strongest capacity were mainly distributed south, whereas those lowest west Heihe-Tengchong Line. Woody...

Abstract Monitoring the resumption of work and production (RWP) is great significance to restoration social order economy after coronavirus disease 2019 (COVID‐19) epidemic. In this study, most critical period epidemic prevention control economic recovery was divided into four phases according changes in emergency response levels during China, based on VIIRS I‐Band 375‐m active fire data (VNP14IMG), NO 2 tropospheric vertical column density (TVCD) data, intracity travel intensity...

The characteristic town (CT, or Te Se Xiao Zhen in Chinese) program is among the most important drivers of China’s new urbanization. However, aroused countrywide concerns about its rapid elevation, excessive real estate construction, high investment risk, and severe construction homogenization. Despite policy’s dissemination, there needs to be a theoretical basis practical guidance for local government evaluate CT candidates ensure feasibility sustainability this novel urbanization practice....

It is an important deployment of the Party Central Committee and State Council to fully promote employment college graduates with higher quality, salary indicator quality measurement. This paper takes cross-sectional data from a financial economic university in 2020 as sample; whether actual starting high dependent variable; human capital, social labor market explanatory variables uses R establish logistic regression model analyze determinants graduates. Five machine learning methods, SVM,...

What happens when liquidity increases in credit markets and more funds are channeled from borrowers to lenders? We examine this question a general equilibrium model where financial matchmakers help (firms) lenders (households) search out negotiate profitable matches the composition of heterogeneous adjusts satisfy entry conditions. find that enhanced causes by all tends benefit low-quality disproportionately. However, liquid may or not be associated with higher output welfare. The result is...

Cyber-insurance has been employed as the mean to transfer cyber risks an insurance company, i.e., insurer. Thereby users are covered by alleviate loss from threats. In this work, we consider security vendors (e.g., Symantec) cyber-insurers selling cyber-insurance in market. Security service will be attached for purpose reduce probability of paying claims, where level is measured quality. Our proposed model consists two stages, Stackelberg game. first stage, set price charging while these...

Abstract Based on panel data of A-share listed companies in Shanghai and Shenzhen Stock Exchange from 2013 to 2017, according the "Upper echelons theory", relation between gender characteristics CFO earnings management was empirically tested with ordinary least squares(OLS) regression model. The study proves that:(1)CFO has a significant impact management. Compared company male CFO, female lower overall level (2)The higher education stronger negative correlation degree. This paper provides...

A big data service is any data-originated resource that offered over the Internet. The performance of a depends on bought from collectors. However, problem optimal pricing and allocation in services not well-studied. In this paper, we propose an auction-based market model. We first define cost utility based impact size analytics, e.g., machine learning algorithms. are considered as digital goods uniquely characterized with "unlimited supply" compared to conventional which limited. therefore...
