Organizational scientists have historically assessed personality via self-reports, but there is a growing recognition that personality ratings from observers offer superior prediction of job performance compared to targets' self-reports. Yet, the origin of these differences remains unclear: do observers show predictive validity advantages (a) because they have a clearer lens into how targets' thoughts, feelings, and desires translate to their behaviors (), (b) because they infer personality from how targets characteristically adapt their behaviors to situations (), or (c) because they omit targets' unexpressed, internal aspects of personality ()? With a sample of 422 cadets at a highly selective military educational institute in South Korea, we applied (McAbee & Connelly, 2016) Trait-Reputation-Identity (TRI) Model to decompose consensus and discrepancy in multirater personality data. The variance associated with reputations (the unique personality insights held by observers) dominated the prediction for conscientiousness and agreeableness in predicting all criteria.

Evidence suggests anti-tumor activities of glucosamine-hydrochloride (GS-HCl). In the present study, we investigated anti-proliferative, growth suppressive and/or pro-apoptotic effects of GS-HCl on YD-8 human oral squamous cell carcinoma (OSCC) cells. Fundamentally, treatment with GS-HCl strongly inhibited proliferation and induced apoptosis in YD-8 cells, as determined by MTS and DNA fragmentation analyses.

Mesenteric venous thrombosis is a clinically very rare disease, and may cause bowel infarction and gangrene. Difficulty in the diagnosis the disease due to its non-specific symptoms and low prevalence can cause a clinically fatal situation. Mesenteric venous thrombosis may be caused by both congenital and acquired factors, and protein C deficiency, which is a very rare genetic disorder, is one of many causes of mesenteric thrombosis.
