Heritability of justice sensitivity

Justice is one of fundamental principles in human evolution, and justice sensitivity, both from the proself perspective (e.g., as victim) and the prosocial perspective (e.g., as observer, beneficiary, and perpetrator), matters in mental wellness and social interaction. However, it remains unclear to what extent individual difference in justice sensitivity is influenced by genetic versus environmental factors. Using a sample with 244 twin pairs, the present research was an attempt to determine what extent genetic factor plays a role in the inter-individual difference of justice sensitivity as well as whether different facets of justice sensitivity, namely, proself and prosocial perspective, share common genetic basis. Results showed that (1) all the four facets of justice sensitivity were moderately heritable (21%–33%) and that the non-shared environmental factors accounted for the rest variations (67%–79%); (2) associations between the prosocial facets of justice sensitivity were driven by common genetics (rg: .50–.65) and non-shared environmental (re: .24–.65) influences, whereas no strong evidence supported a genetic correlation between proself and prosocial justice sensitivity. The current findings provide novel evidence that sensitivity to injustice, especially to others’ suffering, is fundamentally grounded upon genetic origin, thus shedding light on the nature and nurture aspects of justice behavior.

In order to improve the particle identification capability of the Beijing Spectrometer III (BESIII),t is proposed to upgrade the current endcap time-of-flight (ETOF) detector with multi-gap resistive plate chamber (MRPC) technology. Aiming at extending ETOF overall time resolution better than 100ps, the whole system including MRPC detectors, new-designed Front End Electronics (FEE), CLOCK module, fast control boards and time to digital modules (TDIG), was built up and operated online 3 months under the cosmic ray. The main purposes of cosmic ray test are checking the detectors' construction quality, testing the joint operation of all instruments and guaranteeing the performance of the system. The results imply MRPC time resolution better than 100ps, efficiency is about 98%燼nd the noise rate of strip is lower than 1Hz/(scm2) at normal threshold range, the details are discussed and analyzed specifically in this paper. The test indicates that the whole ETOF system would work well and satisfy the requirements of upgrade.

It is proposed to upgrade the endcap time-of-flight (ETOF) of the Beijing Spectrometer III (BESIII) with multi-gap resistive plate chamber (MRPC), aiming at overall time resolution about 80 ps. After the entire electronics system is ready, some experiments, such as heat radiating, irradiation hardness and large-current beam tests,are carried out to certify the electronics' reliability and stability. The on-detector test of the electronics is also performed with the beam at BEPCII E3 line, the test results indicate that the electronics system fulfills its design requirements.
