Job burnout has long been recognized as a common occupational hazard among correctional workers. Although past studies have investigated the effects of job-related characteristics on correctional staff burnout in Western societies, this line of research has largely been absent from the literature on community corrections in China. Using data collected from 225 community correction workers in a Chinese province, this study assessed the effects of positive and negative job characteristics on occupational burnout. Positive job characteristics included job autonomy, procedural justice, and role clarity. Negative characteristics included role conflict, job stress, and job dangerousness. As expected, role clarity tended to reduce burnout, whereas role conflict, job stress, and job dangerousness were likely to produce greater burnout among Chinese community correction workers. Male correctional officers were also subjected to a higher level of burnout than their female coworkers. Implications for future research and policy were discussed.

“Carbon neutrality, carbon peaking” is China’s national commitment to the whole world about its plans to manage global climate change. China faces many severe challenges in fulfilling its commitments to reduce emissions. China’s digital economy is currently booming, and whether it can provide opportunities for reducing regional carbon emissions is worth exploring. This study constructed a comprehensive system to evaluate the development of its digital economy based on China’s regional data and empirically tested the direct, indirect, and spatial effects of the comprehensive development of digital economy on regional carbon emissions. In addition, it examined the special stage characteristics using a Hansen threshold model. This study found the following: first, the digital economy significantly suppresses carbon emissions in general, notably with a spatial spillover effect to neighboring provinces. Secondly, an analysis of the mechanism shows that the comprehensive development of a digital economy can restrain regional carbon emissions through industrial progress and the optimization of energy consumption. Third, there are double thresholds, special driving trends and an “inverted N-type” relationship with development. Fourth, a spatial heterogeneity analysis revealed that significant “local” and “neighboring” impacts on the reduction of carbon emissions only exist in the central and eastern areas. This study has a reference value for releasing the dividend of digital economy development and reducing carbon emissions.

The interaction between four polymer binder molecules and 2,6-dipicrylamino-3,5-dinitropyridine (PYX) molecules was determined through the analysis of surface electrostatic potential and deformation electron density. The binding energy, mechanical properties, and cohesive energy density (CED) of Polymer Bonded Explosives (PBXs) based on PYX at different temperatures were studied. By comparing the binding energies of four polymer binders and three PYX crystal surfaces at five temperatures, it was found that the surface of PYX (011) was the most suitable surface, and the binding energy of EPDM (Ethylene Propylene Diene Monomer) and PYX (011) was the strongest by comparing the four polymer-binding molecules with the surface of PYX (011) at the same temperature. The CED values and distribution of CED for four PYX-based PBXs were analyzed with the change in temperature, and the conclusion was drawn that temperature had little influence on CED values. The descending order of CED values of four PYX-based PBXs at the same temperature was as follows: PYX/F2641 > PYX/F246G > PYX/F2311 > PYX/EPDM. At 298 K, the addition of polymer binders significantly changed the mechanical properties of PYX and reduced the stiffness and deformation resistance of the system. In addition, the C12–C44 value of the four systems was positive, which meant that the system was ductile. The order of toughness and ductility is as follows: PYX/F246G > PYX/F2311 > PYX/F2641 > PYX/EPDM. The addition of the polymer binder was helpful for the stability of the explosive. The theoretical detonation velocity and detonation pressure of the PBX systems were calculated.
