The capacity of servicemembers with amputation to return to duty after combat-related amputation and the associated disabilities remains largely unknown. The purpose of this study was to examine the disabling conditions and return to duty rates of servicemembers with amputation across all service branches following major limb amputations from September 2001 through July 2011. Pertinent medical ...

PURPOSE The purpose of this study was to investigate sleep habits, sleep disturbance, and circadian types, and to identify factors influencing sleep disturbance in nursing students. METHODS Participants were 140 senior nursing students. The data were collected from May 19 to 27, 2008 using self-report questionnaires. RESULTS 1) Evening type delayed sleep-wake schedules were more frequent th...

Coexistence of Wi-Fi and LTE in unlicensed spectrum (LTE-U) is recently drawing significant concern in industry. In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS) coexist by allowing LTE-U devices transmit their signals only in predetermined duty ...

Anterior cruciate ligament (ACL) injuries occur repeatedly in Special Operations Forces (SOF). In this study, we sought to determine whether military patients requiring a second (i.e., revision) ACL reconstruction in the same knee had a lower rate of return to full duty and greater chance of medical discharge versus those undergoing first-time (i.e., primary) ACL knee surgery. A single- institu...

Many people were outraged when Richard Lamm claimed that old people had a duty to die. Modern medicine and an individualistic culture have seduced many to feel that they have a right to health care and a right to live, despite the burdens and costs to our families and society. But in fact there are circumstances when we have a duty to die. As modern medicine continues to save more of us from ac...

BACKGROUND Increasing evidence associates excess refined sugar intakes with obesity, Type 2 diabetes and heart disease. Worryingly, the estimated volume of sugary drinks purchased in the UK has more than doubled between 1975 and 2007, from 510 ml to 1140 ml per person per week. We aimed to estimate the potential impact of a duty on sugar sweetened beverages (SSBs) at a local level in England, h...

Psychiatry has been struggling for nearly 40 years to make sense of the duty to protect. The great jurisdictional disparity as to what constitutes the duty has been a significant contributing factor. The American Psychiatric Association (APA) released the Model Statute in 1987 to establish a framework to guide legislators and courts toward consensus, to some effect. In response to case law and ...

Aiming at researching the QoS performance of slotted CSMA/CA mechanism in beacon-enabled IEEE802.15.4, this paper analyzes the effect relationship between QoS and superframe parameters through analytic mathematical model and simulation method. Firstly, the nodes’ sleeping time of WSNs is deduced from duty cycle mathematical formulation. Therefore, the energy consumption directly related to slee...

The original Tarasoff decision created a duty for California psychotherapists to warn potential victims of their patients. After rehearing the matter two years later, the California Supreme Court, in the landmark second Tarasoff decision, changed the duty to warn to a duty to protect potential victims, with warning as only one of the options for discharging that duty. Despite this change, the T...

The decline in biodiversity is a worldwide phenomenon, with current rates of species extinction more dramatic than any previously recorded. Habitat loss has been identified as the major cause of biodiversity decline. In this article we suggest that a statutory duty of care would complement the current mix of policy options for biodiversity conservation. Obstacles hindering the introduction of a...
