1. Defensive individuals, termed soldiers, have recently been discovered in aphids, Soldiers are typically early instar larvae, and in many species the soldiers are reproductively sterile and morphologically and behaviourally specialized. 2. Since aphids reproduce parthenogenetically, we might expect soldier production to be more widespread in aphids than it is. We suggest that a more useful wa...
OBJECTIVE Deployment to a combat zone is undoubtedly an extremely stressful experience. It was hypothesized that, when faced with an impending wartime deployment, soldiers with prior combat experience would report minimal emotional problems accompanied by high rates of somatic complaints compared with combat-naive soldiers. METHODS Self-reports of posttraumatic stress disorder (PTSD) and affe...
The purpose of this study was to explore the relationship between job burnout and neuroendocrine indicators in soldiers living in a harsh environment. Three hundred soldiers stationed in the arid desert and 600 in an urban area were recruited. They filled in the Chinese Maslach Burnout Inventory questionnaire. One hundred soldiers were randomly selected from each group to measure their levels o...
Background and Aim: Suicidal thoughts are one of the main risk factors for suicide attempts, so understanding the factors associated with suicidal ideation in soldiers can be important in preventing and treating suicide in military environments. The aim of this study was to investigate the relationship between the demographic factors of soldiers and their experience of suicidal ideation. Method...
BACKGROUND The prevalence of suicide among U.S. Army soldiers has risen dramatically in recent years. Prior studies suggest that most soldiers with suicidal behaviors (i.e., ideation, plans, and attempts) had first onsets prior to enlistment. However, those data are based on retrospective self-reports of soldiers later in their Army careers. Unbiased examination of this issue requires investiga...
Injuries are a common occurrence in young, active civilian and military populations. This study examined injury incidence and the association of musculoskeletal injuries with age and physical fitness in soldiers. Subjects were a cohort of 298 male soldiers assigned to an infantry battalion in Alaska. The soldiers' ages were obtained from the battalion records and their physical fitness was asse...
The study of organic response during combat is poorly reported in specific literature, despite being essential to improve soldiers training. The aim of the present research was to study the body composition and organic response during a treadmill test simulating the attack maneuver of a light infantry company, studying the differences between soldiers gender. Body composition and organic respon...
We integrate phylogenetic information with data on genetic relatedness, inbreeding, sex ratios, reproductive skew, host-plant use, gall morphology, soldier defensive behaviour, kleptoparasite pressure, and demography to evaluate hypotheses for the origin and evolution of soldier castes in Australian gall thrips. Necessary and sufficient conditions for the single origin of thrips soldiers appear...
A study was performed at the Garrison Medical Centre, Larkhill to assess the incidence of skin tattoos in a sample of soldiers. The soldiers were questioned with the aim of establishing where they had had their tattoos done, identifying any factors involved in becoming tattooed and assessing what proportion later regretted their actions. The study included 450 male soldiers. Assessment was by a...
Obesity is often associated with poor heat tolerance. This case-control study was to determine the effect of obesity measured by the Body Mass Index (BMI) on the occurrence of heat disorders. The subjects, 218 soldiers with heat disorders and 537 controls, were matched for age and sex. Obesity was defined as a BMI of greater than 27. The odds ratio for obese soldiers was 3.53; however, their re...
