Dialecticism refers to the cognitive tendency to tolerate contradiction and is more frequently found among East Asian than North American cultures. In Study...

Bleeding disorders are usually taken to mean coagulopathies with reduced clotting of the blood but also encompass disorders characterised by abnormal platelet function or blood vessel walls that result in increased bleeding. Bleeding disorders may result from faults at many different levels in the coagulation process. They can range from severe and life-threatening conditions, such as haemophil...

Approximately 90% of patients with cirrhosis will have developed gastro-oesophageal varices within 10 yr. Oesophageal variceal haemorrhage is a devastating complication of cirrhosis with mortality as high as 25–50%. Therefore, prophylactic measures before the first bleed are crucial. If patients survive a variceal bleed, there is approximately a 70% risk that they will have a further bleed with...

Four methodologically diverse studies tested the hypothesis that provocation severity and relationship commitment interact to predict aggression toward one’s romantic partner, with the aggression-prom...
