Believe it or not:Exploring the relationship between dogmatism and openness within non-religious samples

Personality and dogmatic thinking within religious individuals have been examined by previous research, but neglected for non-religious individuals. In this experiment, we distinguish between two types of non-religious groups; those who ascribe themselves to an identity (atheists) and those who do not (no beliefs in particular). A total of 103 non-religious individuals (36% atheists and 64% with no particular beliefs) completed an online questionnaire measuring dogmatism and openness traits, with an additional Christian group (n = 91) serving as a control. After confirming a relationship between identity salience and dogmatism, and validating a measure of dogmatism (DOG) in both non-religious groups, we note key personality differences between the two. Those with no beliefs in particular demonstrated a traditional negative correlation between openness and dogmatism (along with Christians) while these variables correlated positively for atheists (in particular, on ‘unconventionality’). This study is the first to establish differences between the relationship of dogmatism and openness within non-religious populations and explain these differences through group identity. Thus, identity strength and group belief systems are suggested to be key contributors to observed group differences between non-religious individualsPeer reviewe

Case-control analysis of prehospital death and prolonged field care survival during recent US military combat operations

BACKGROUND: Quantification of medical interventions administered during prolonged field care (PFC) is necessary to inform training and planning. MATERIALS AND METHODS: Retrospective cohort study of Department of Defense Trauma Registry casualties with maximum Abbreviated Injury Scale (MAIS) score of 2 or greater and prehospital records during combat operations 2007 to 2015; US military nonsurvivors were linked to Armed Forces Medical Examiner System data. Medical interventions administered to survivors of 4 hours to 72 hours of PFC and nonsurvivors who died prehospital were compared by frequency-matching on mechanism (explosive, firearm, other), injury type (penetrating, blunt) and injured body regions with MAIS score of 3 or greater. Covariates for adjustment included age, sex, military Service, shock, Glasgow Coma Scale, transport team, MAIS and Injury Severity Score (ISS). Sensitivity analysis focused on US military subgroup with AIS/ISS assigned to nonsurvivors after autopsy. RESULTS: The total inception cohort included 16,202 casualties (5,269 US military, 10,809 non-US military), 64% Afghanistan, 36% Iraq. Of US military, 734 deaths occurred within 30 days, nearly 90% occurred within 4 hours of injury. There were 3,222 casualties (1,111 US military, 2,111 non-US military) documented for prehospital care and died prehospital (691) or survived 4 hours to 72 hours of PFC (2,531). Twenty-five percent (815/3,222) received advanced airway, 18% (583) ventilatory support, 9% (281) tourniquet. Twenty-three percent (725) received blood transfusions within 24 hours. Of the matched cohort (1,233 survivors, 490 nonsurvivors), differences were observed in care (survivors received more warming, intravenous fluids, sedation, mechanical ventilation, narcotics, antibiotics; nonsurvivors received more intubations, tourniquets, intraosseous fluids, cardiopulmonary resuscitation). Sensitivity analysis focused on US military (732 survivors, 379 nonsurvivors) showed no significant differences in prehospital interventions. Without autopsy information, the ISS of nonsurvivors significantly underestimated injury severity. CONCLUSION: Tourniquets, blood transfusion, airway, and ventilatory support are frequently required interventions for the seriously injured. Prolonged field care should direct resources, technology, and training to field technology for sustained resuscitation, airway, and breathing support in the austere environment.

Genomic diversity of bacteriophages infecting Microbacterium spp.

The bacteriophage population is vast, dynamic, old, and genetically diverse. The genomics of phages that infect bacterial hosts in the phylum Actinobacteria show them to not only be diverse but also pervasively mosaic, and replete with genes of unknown function. To further explore this broad group of bacteriophages, we describe here the isolation and genomic characterization of 116 phages that infect Microbacterium spp. Most of the phages are lytic, and can be grouped into twelve clusters according to their overall relatedness; seven of the phages are singletons with no close relatives. Genome sizes vary from 17.3 kbp to 97.7 kbp, and their G+C% content ranges from 51.4% to 71.4%, compared to ~67% for their Microbacterium hosts. The phages were isolated on five different Microbacterium species, but typically do not efficiently infect strains beyond the one on which they were isolated. These Microbacterium phages contain many novel features, including very large viral genes (13.5 kbp) and unusual fusions of structural proteins, including a fusion of VIP2 toxin and a MuF-like protein into a single gene. These phages and their genetic components such as integration systems, recombineering tools, and phage-mediated delivery systems, will be useful resources for advancing Microbacterium genetics
