Gun theft is an important source of guns used by criminals. Yet no empirical work has focused on the characteristics of gun owners that distinguish those who have had their guns stolen from those who have not. In this study, we examine the demographics and behavioral characteristics of gun owners who report having had a gun stolen.

All people share a need for safety. Yet, people’s pursuit of safety can conflict when it comes to guns, where some people perceive guns as a means to safety and others perceive guns as a threat to safety. We examined this conflict on a United States college campus that prohibits guns. We distinguished between people (N = 11,390) who (a) own a gun for protection, (b) own a gun exclusively for reasons other than protection (e.g., collecting, sports), and © do not own a gun. Protection owners felt less safe on campus, supported allowing guns on campus, and reported that they and others would feel safer and that gun violence would decrease if they carried a gun on campus. Non-owners and non-protection owners felt the reverse. The findings suggest that protection concerns, rather than gun-ownership per se, account for diverging perceptions and attitudes about guns and gun control.

Mass public shootings are typically followed by a spike in gun sales as well as calls for stricter gun control laws. What remains unclear is whether the spike in gun sales is motivated by increased threat perceptions or by concerns about gun control, or whether the sales are mainly driven by non-owners purchasing guns or gun owners adding to their collection. Two surveys of gun owners and non-owners, conducted immediately before and after the Orlando shooting, allowed us to assess its impact on threat perceptions and on gun-purchasing intentions. Although there was a minor impact on threat perceptions of non-owners, neither group reported any increased gun-purchasing intentions or an increased need of a gun for protection and self-defense. We suggest that these responses are representative for the majority of Americans and, therefore, people who are influenced by mass shootings to buy guns are probably an atypical minority.

One way that guns get into the wrong hands is via gun sales without a background check. While the large majority of Americans support laws requiring universal background checks, no prior study has assessed whether Americans think it is acceptable behaviour to sell a gun to a stranger without a background check, whether or not there is a law against it.

The First World War was a huge tragedy for mankind, but, paradoxically, it represented a source of significant progress in a broad series of human activities, including medicine, since it forced physicians to improve their knowledge in the treatment of a large number of wounded soldiers. The use of heavy artillery and machine guns, as well as chemical warfare, caused very serious and life-threatening lesions and wounds. The most frequent causes of death were not mainly related to gunshot wounds, but rather to fractures, tetanus and septic complications of infectious diseases. In the first part of this article, we describe the surgical procedures and medical therapies carried out by Italian physicians during the First World War, with the aim of treating wounded soldiers in this pre-antibiotic era. Antibacterial solutions, such as those of Dakin-Carrel and sodium hypochlorite and boric acid, the tincture of iodine as well as the surgical and dressing approaches and techniques used to remove pus from wounds, such as ignipuncture and thermocautery or lamellar drainage are reported in detail. In the second part of the paper, the organization of the Italian military hospitals network, the systems and tools useful to transport wounded soldiers both in the front lines and in the rear is amply discussed. In addition, the number of soldiers enrolling, and those dying, wounded or missing during the Great War on the Italian front is estimated.
