As one of China’s key poverty-reduction initiatives, poverty alleviation relocation (PAR) unavoidably results in the reshaping of neighboring social networks. This study equally focused on the changes in the scope of social interaction and in the intergroup social support of the two primary stakeholders of PAR in a rural–rural relocation context: the migrant and local groups. In 2019 and 2021, two surveys were conducted in four different types of resettlements: centralized, adjacent, enclave, and infill. To provide decision makers with broad references for sustainable PAR planning, the social changes were compared by groups, types, and years. In general, the migrant group had more significant scope expansion or narrowing in social interaction than the local group, and they were more willing to seek intergroup social support. Specifically, the centralized type was the superior choice since it was well-expanded and group-balanced; the adjacent type was also a good choice in the long term because of its rapid improvement in the later phase; the enclave type should be a last resort because of its persistently negative impact; and the infill type was a good option in the short term, as it rarely improved in the later stage. Furthermore, the personal socioeconomic attributes associated with the above social changes, claims laid to the spaces, and economic benefits and limitations were explored for a more comprehensive understanding.

In order to improve the viscoelasticity of bitumen, several modifiers were compounded with it, including SBS, reclaimed rubber powder, tackifier, plasticizer, and oil stabilizer, to produce High-viscosity and High-elastic Modified Bitumen (HVE-MB). The viscoelasticity and various physical and rheological properties of the bitumen were evaluated using a number of factors, such as dynamic viscosity at 60 °C, elastic recovery, penetration, softening point, ductility, and DSR. By comparing different types of modifiers and the content of SBS, it was found that the viscoelasticity of the original bitumen was significantly improved by adding the modifiers. In comparison to the original bitumen, the dynamic viscosity of the HVE-MB increased by more than 110 times, the elastic recovery rate more than doubled, the softening point and ductility improved, and the penetration decreased. As the content of SBS increased, the improvement in the properties became more significant. The workability of HVE-MB satisfies the requirement of less than 2.5 °C by adding the suitable dosage of stabilizer. On the other hand, the content of SBS can be adjusted based on the specific requirements. It is a sustainable and economic way to use the reclaimed rubber powder to improve the technical performance of bitumen.

In recent years, the phenomenon of urban warming has become increasingly serious, and with the number of urban residents increasing, the risk of heatstroke in extreme weather has become higher than ever. In order to mitigate urban warming and adapt to it, many researchers have been paying increasing attention to outdoor thermal comfort. The mean radiant temperature (MRT) is one of the most important variables affecting human thermal comfort in outdoor urban spaces. The purpose of this paper is to predict the distribution of MRT around buildings based on a commonly used multilayer neural network (MLNN) that is optimized by genetic algorithms (GA) and backpropagation (BP) algorithms. Weather data from 2014 to 2018 together with the related indexes of the grid were selected as the input parameters for neural network training, and the distribution of the MRT around buildings in 2019 was predicted. This study obtained very high prediction accuracy, which can be combined with sensitivity analysis methods to analyze the important input parameters affecting the MRT on hot summer days (the days with the highest air temperature over 30 °C). This has significant implications for the optimization strategies for future building and urban designers to improve the thermal conditions around buildings.

The Eaves Gallery (EG) along the street as a form of Chinese traditional dwelling was special architecture form for preventing pedestrians from rains and snows while walking through or shopping which has played important roles in the ancient commercial activities. In the past, the studies about EG focused on architectural history, style, evolution in the separated specific local area. It helped the promotion of social attention to EG for protection and renewal. However, the protection and renewal conditions of EG are different in various regions of China. Few studies have done to compare and overview the characteristics of EG in these various regions. In this study, typical EG along the streets in Hubei, Bashu, Jiangzhe along Yangtze River regions from east to west of China were taken as case studies and are explicated based on the comparison and analyzing field distribution mode, space combination, spatial scale, and function. Thus, the spatial functional characteristics of EG in these three regions are divided into unitary type, conversion type and mixed type. The outcome will serve as a comparative basis for the existential form and spatial characteristics of extant traditional EG accompanied by optimum protection and renewal policy discussion in the future.
