Contact between people from different groups triggers specific individual- and group-level responses, ranging from attitudes and emotions to welfare and health outcomes. Standard social psychological perspectives do not yet provide an integrated, causal model of these phenomena. As an alternative, we describe a coalitional perspective. Human psychology includes evolved cognitive systems designed to garner support from other individuals, organize and maintain alliances, and measure potential support from group members. Relations between alliances are strongly influenced by threat detection mechanisms, which are sensitive to cues that express that one's own group will provide less support or that other groups are dangerous. Repeated perceptions of such threat cues can lead to chronic stress. The model provides a parsimonious explanation for many individual-level effects of intergroup relations and group-level disparities in health and well-being. This perspective suggests new research directions aimed at understanding the psychological processes involved in intergroup relations.

The genetic foundations underlying the observed disease resistance in certain indigenous pig breeds, notably the Min pigs of China, present a compelling underexplored subject of study. Exploring the mechanisms of disease resistance in these breeds could lay the groundwork for genetic improvements in pig immunity, potentially augmenting overall pig productivity. In this study, whole blood samples were collected from pre- and post- swine fever vaccinated Min and Large White pigs for transcriptome sequencing.

Objectives: We aimed to characterize a craniofacial skeletal phenotype (CSP) of adult obstructive sleep apnea (OSA) patients from a multidimensional perspective, exploring the impact of transverse skeletal discrepancy (TSD) on multivariable polysomnographic profiles.
Materials And Methods: This retrospective, cross-sectional study included 102 adult OSA patients. Sagittal, vertical, and transverse skeletal patterns were categorized on the cone beam computed tomography images.

Terror Management Theory (TMT) holds that mortal threats bolster people's desire to support their worldviews, which may contribute to increased outgroup bias. In 2020, two events likely increased mortality salience and death anxiety: COVID-19 and the Black Lives Matter (BLM) protests that followed George Floyd's murder. We used Project Implicit data to investigate their impact on implicit anti-Black bias, controlling for demographic variables.

Yet, the role of empathy in fostering prosocial responses during societal crises has not gained enough attention. Our study uses the onset of Russia's war on Ukraine to examine three key questions: (1) Is empathy related to attitudes toward pro-refugee policies? (2) Does empathy correlate with a higher tolerance for diverse opinions on refugee policies? (3) Is empathy linked to perceived interpersonal closeness toward social in- and outgroups, including refugees?
Methods And Results: Using observational data from online surveys conducted with a largely representative quota sample from Germany (N = 1199-1631) during the initial months of the war, we found that empathy was associated with significantly higher support of pro-refugee policies, driven primarily by empathic concern.

Objective: From the beginning of the COVID-19 pandemic, there has been a proliferation of anti-Asian racism. In addition to being personal targets of racism, members of the Asian American community have also been vicariously exposed to repeated news and social media stories about anti-Asian racism. Emerging research suggests that vicarious exposure to racism during the pandemic is associated with decreased well-being, although mechanisms of action are not yet clear.
