This book focuses on why and how to achieve digital transformation for enterprises and organizations by introducing cases in China. Its purpose is to highlight the importance and improve the understanding for digital transformation and related issues, like human resource allocation, and how to improve the efficiency and success rate in a low-cost and low-risk way. In this way, the cases in the book avoid the most common traps during the digital transformation process, enabling R&D and business personnel, and data practitioners in the organization to figure out the implementation and processes involved, and hence better understand how to work with senior management team when implementing the transition plan. The middle and senior level managers such as company executives, presidents in banks and universities, and officials in government, are also the target audience.

Urban land expansion (ULE) is a crucial factor for socioeconomic and environmentally sustainable development. However, nowadays, the unprecedented scale of high-speed railway (HSR) construction in China could exert an important influence on ULE. This manuscript first reveals the influence mechanism of HSR on ULE and then employs difference-in-difference (DID) models to investigate this effect based on the data of 280 prefectures and above level cities of 2001-2016. We analyze that HSR exerts a joint effect on ULE from the territorial and local levels and then affects urban land-use intensity (ULUI). HSR opening and HSR station distance both have notably positive effects on ULE, with elastic coefficients of 4.1% and 0.5%, respectively. HSR opening and HSR station distance also both exert positive effects on ULE of the central, eastern region cities and large cities of China, while for the western region and small to medium cities, they are not significant. The impact of HSR station distance on ULUI is negative with a significance level of 0.073, while the impact of HSR opening on ULUI is not significant. Lastly, relevant policy implications are proposed to alleviate urban land waste and spatial disequilibrium under the context of HSR building. This study can provide an important basis for sustainable urban land allocation.

During the pandemic, the mortality salience of COVID-19 has affected everyone. The public is extremely sensitive to food safety, especially cold chain food and imported food. This research is based on the terror management theory, protective motivation theory, and self-construal theory. It proposes an integrated dual-path framework to explore the different mechanisms that mortality salience has on food safety behavior. The result of three experiments verified our conjectures. First, mortality salience positively affects individuals' food safety behavior. More importantly, we found the dual-path mechanism that underlies the effect, that is, the mediating of self-protective motivation and prosocial motivation. In addition, different self-construals make the confirmed effect clear. These findings provide implications for the government to protect public food safety and health.

Abstract. The Tangshan region is one of the most seismically active areas in
the North China, and the 1976 M 7.8 earthquake occurred on 28 July near
the Tangshan fault zone. The Matouying enhanced geothermal system (EGS)
field is located ∼90 km away from the city of Tangshan. Since late 2020, preliminary hydraulic stimulation tests have been conducted at
depths of ∼3965–4000 m. Fluid injection into geothermal reservoir facilitates a heat exchanger system. However, fluid injection may also induce earthquakes. In anticipation of the EGS operation at the Matouying uplift, it is essential to assess how the fault slip potential of the nearby active and quiescent faults will change in the presence of fluid injection. In this study, we first characterize the ambient stress field in the Tangshan region by performing stress tensor inversions using 98 focal-mechanism data (ML≥2.5). Then, we estimate the principal stress magnitudes near the Matouying EGS field by analyzing in situ stress measurements at shallow depths (∼600–1000 m). According to these data, we perform a quantitative risk assessment using the Mohr–Coulomb framework in order to evaluate how the main active faults might respond to hypothetical injected-related pore pressure increases due to the upcoming EGS production. Our results mainly show that most earthquakes in the Tangshan seismic region have occurred on the faults that have relatively high fault slip potential in the present ambient stress field. At well distances of less than 15 km, the probabilistic fault slip potential on most of the boundary faults increases with continuing fluid injection over time, especially on the faults with well distances of ∼6–10 km. The probabilistic fault slip potential (fsp) increases linearly with the fluid injection rate. However, the fsp values decrease exponentially with increased unit permeability. The case study of the Matouying EGS field has important implications for deep geothermal exploitation in China, especially for Gonghe EGS (in Qinghai Province) and Xiong'an New Area (in Hebei Province) geothermal reservoirs that are close to the Quaternary active faults. Ongoing injection operations in the regions should be conducted with these understandings in mind.
