Garrett Hardin's tragedy of the commons is an analogy that shows how individuals driven by self-interest can end up destroying the resource upon which they all depend. The proposed solutions for humans rely on highly advanced skills such as negotiation, which raises the question of how non-human organisms manage to resolve similar tragedies. In recent years, this question has promoted evolution...

Background

The dissociative experiences scale (DES), developed by Bernstein and Putnam (1986), is commonly used to measure dissociation in clinical populations. It is often used with nonclinical populations to assess how levels of dissociation covary with other psychometric measures. When it is used with nonclinical populations, problems arise because the resulting scores can show severe floor effects and...

Conflict between males and females over whether, when, and how often to mate often leads to the evolution of sexually antagonistic interactions that reduce female reproductive success. Because the offspring of relatives contribute to inclusive fitness, high relatedness between rival males might be expected to reduce competition and result in the evolution of reduced harm to females. A recent st...

CONCLUSION: We found high SSI rates following BCPS in massive weight loss patient population. The independent protective effect of pre-operative antimicrobial prophylaxis is inconsistent with the current guidelines that do not require antimicrobial prophylaxis for clean procedures such as BCPS. Further assessment of antimicrobial prophylaxis in BCPS using a randomized controlled clinical study ...

This paper utilizes focal follow observations of Aka and Efé infants, interviews with Aka mothers, ethnographic reports from researchers work...

this evaluation was undertaken to analyse the overall merit of studies for publication in medical journals. peer review, in which peer experts evaluate the value of a manuscript submitted to a professional journal, is regarded as a crucial step in publication. it helps to ensure that published articles describe experiments that focus on important issues and that the research is well designed an...
