Effects of COVID-19 related economic threat on political conservatism, xenophobia, and racial bias in the United States

The uncertainty-threat model of conservatism posits that people turn to political conservatism to protect themselves from perceived threats; indeed, studies show increases in conservative ideology and outgroup bias following threat priming. The COVID-19 pandemic is an unprecedented threat that has had devastating effects on the health and economic lives of Americans. Concerns surrounding the threat of COVID-19 may have secondary effects on other aspects of American life... Читать дальше...

A possible later stone age painting of a dicynodont (Synapsida) from the South African Karoo

The Horned Serpent panel at La Belle France (Free State Province, South Africa) was painted by the San at least two hundred years ago. It pictures, among many other elements, a tusked animal with a head that resembles that of a dicynodont, the fossils of which are abundant and conspicuous in the Karoo Basin. This picture also seemingly relates to a local San myth about large animals that once roamed southern Africa and are now extinct. This suggests the existence of a San geomyth about dicynodonts.

Lower empathy for face mask wearers is not explained by observer’s reduced facial mimicry

by Sarah D. McCrackin, Jelena Ristic

Facial occlusion alters social processes that rely on face visibility, including spontaneous mimicry of emotions. Given that facial mimicry of emotions is theorized to play an important role in how we empathize or share emotions with others, here we investigated if empathy was reduced for faces wearing masks because masks may reduce the ability to mimic facial expressions. In two preregistered experiments, participants rated their empathy for faces displaying... Читать дальше...

A modeling method for thermal steady-state simulation of the four-layer printed circuit board

by Yabin Zhang, Lin Chen

Thermal simulation of a Printed Circuit Board (PCB) can help identify potential overheating risks in the circuit. The proposed modeling method combines analytical temperature solutions and numerical approximations. Only Fourier-series analytical solutions related to the prepreg-layer surfaces need to be calculated, rather than the entire structure. Heat transfer through the lateral sides of a PCB is approximately considered as part of the compensated heat flux of the insulating-layer surface boundaries. Читать дальше...

Digital transformation and corporate tax avoidance: An analysis based on multiple perspectives and mechanisms

by Qi Zhang, Jinghuai She

Promoting the seamless integration of the digital economy with the real economy, mitigating the adverse impacts of widespread corporate tax avoidance, and optimizing tax governance are critical imperatives in the era of digital economy. This study examines all A-share listed companies from 2007 to 2022 as research samples. It utilizes multiple perspectives including signal theory, information asymmetry theory, and the T-O-E (Technology-Organisation-Environment) framework... Читать дальше...

Suggested guidelines in reporting results from mediation analysis, standardized or unstandardized?

by Mohammad Nahian Ferdous Abrar, Hongmei Zhang, Yu Jiang

Mediation analysis is commonly implemented in psychological, epidemiological, and social behavior studies to identify potential factors that mediate associations between exposures and physical or psychological outcomes. Various analytical tools are available to perform mediation analyses, among which Mplus is widely used due to its user-friendly interface. In practice, sumptuous results provided by Mplus, such as the estimated standardized and unstandardized effect sizes... Читать дальше...

by Feng Ding, Shijun Zhang, Luote Dai

The agglomeration and dispersion of tourist attractions in space greatly affect the development of regional tourism resources and the consumption choice of tourism market. At present, the research on the spatial distribution characteristics of tourist attractions and their influencing factors mainly adopts induction and investigation, and there is a lack of effective statistical models for the research on the spatial distribution of tourist attractions...

by Zhongnan Tian, Peng Liang, Bochao Zhai, Yue Zhou

To investigate the advantageous effects of incorporating industrial solid waste basic oxygen furnace (BOF) slag on the mechanical characteristics of warm-mixed rubber asphalt (WMRA) and hot-mixed rubber asphalt (HMRA) mixture, varying proportions of BOF slag were substituted for limestone coarse aggregates (0%, 25%, 50%, and 75%). Additionally, a 1.5% dosage of Sasobit warm-mixed modifier was introduced to prepare the rubber asphalt. Subsequent to preparation... Читать дальше...

Effects of acute stress on biological motion perception

by Jifu Wang, Fang Shi, Lin Yu

Biological motion perception is an essential part of the cognitive process. Stress can affect the cognitive process. The present study explored the intrinsic ERP features of the effects of acute psychological stress on biological motion perception. The results contributed scientific evidence for the adaptive behavior changes under acute stress. After a mental arithmetic task was used to induce stress, the paradigm of point-light displays was used to evaluate biological motion perception. Читать дальше...
