W Christopher Carleton, David Campbell, Mark Collard
Statistical time-series analysis has the potential to improve our understanding of human-environment interaction in deep time. However, radiocarbon dating-the most common chronometric technique in archaeological and palaeoenvironmental research-creates challenges for established statistical methods. The methods assume that observations in a time-series are precisely dated, but this assumption is often violated when calibrated radiocarbon dates are used because they usually have highly irregular uncertainties...

Di Fang, Renyuan Sun, Jeffrey R Wilson
Recent advances in statistical methods enable the study of correlation among outcomes through joint modeling, thereby addressing spillover effects. By joint modeling, we refer to simultaneously analyzing two or more different response variables emanating from the same individual. Using the 2011 Bangladesh Demographic and Health Survey, we jointly address spillover effects between contraceptive use (CUC) and knowledge of HIV and other sexually transmitted diseases. Jointly modeling these two outcomes is appropriate because certain types of contraceptive use contribute to the prevention of HIV and STDs and the knowledge and awareness of HIV and STDs typically lead to protection during sexual intercourse...

This study addressed school-contextual features of social disorder in relation to sixth-grade students' experiences of bullying victimization and mental health complaints. It investigated, firstly, whether the school's concentrations of behavioural problems were associated with individual students' likelihood of being bullied, and secondly, whether the school's concentrations of behavioural problems and bullying victimization predicted students' emotional and psychosomatic health complaints. The data were derived from the Swedish National Survey of Mental Health among Children and Young People, carried out among sixth-grade students (approximately 12-13 years old) in Sweden in 2009...

Membrane curvature sensing, where the binding free energies of membrane-associated molecules depend on the local membrane curvature, is a key factor to modulate and maintain the shape and organization of cell membranes. However, the microscopic mechanisms are not well understood, partly due to absence of efficient simulation methods. Here, we describe a method to compute the curvature dependence of the binding free energy of a membrane-associated probe molecule that interacts with a buckled membrane, which has been created by lateral compression of a flat bilayer patch...

BACKGROUND: Non-operative management (NOM) is a standard treatment method for solid organ injuries worldwide. There is no consensus on the management of gunshot wounds (GSW) because of the higher frequency of hollow viscus injuries (HVI) and the unpredictable depth of tissue damage produced by kinetic energy transfer during retardation of the bullet. Here we aimed to reevaluate indications for surgery and NOM based on our pediatric patients with abdominal GSW. METHODS: We performed a retrospective analysis of patients evaluated and treated for abdominal GSW at University of Dicle between January 2010 and October 2016...
