We provide a historical background on Ziemba’s experiences and research on the bondstock earnings yield differential model (BSEYD), from the time he first used it in Japan in 1988 through to the present in 2014. Over this period, the model has called many crashes, but not all. Those called have had high interest rates in long term bonds relative to the trailing earnings to price ratio. In gener...

background in many industries, noise is attributed as the most prevalent harmful agent threatening workers' health. geographic information system (gis) is an applicable surveying tool in civil engineering. but, the use of gis for noise and hearing loss screening seems to be partly a new approach. objectives this study aimed to apply gis in noise and hearing loss screening in the production hall...

Background: An estimated 125,711 face-lifts and 54,281 neck-lifts were performed in 2015. Regardless of the technique employed, facial and neck flap elevation carries with it anatomical risk of which any surgeon performing these procedures should be aware of. Statistics related to anterior jugular vein injury during these procedures have not been published. Objective: To define a "danger zone" ...

The Federal Employer's Liability Act (FELA) exempts employers from providing mental health coverage to railway drivers who suffer work-related psychological trauma as the result of an incident that does include a threat of imminent direct physical impact. Tension exists between this legislation and the Posttraumatic Stress Disorder (PTSD) literature. Neurobiological research demonstrates that P...

This article uses grounded theory methods to research the history of a therapeutic community and highlights the possibilities of ‘being able to learn’ as an aim for history of medicine research. For this case study, processes of research and learning allow consideration of the ‘dilemma of paternalism’ and the interaction between history, policy and practice. How can students enter into discours...

According to the propagation and destruction characteristics of mobile phone viruses, a virus detection model based on the Danger Theory is proposed. This model includes four phases: danger capture, antigen presentation, antibody generation and antibody distribution. In this model, local knowledge of mobile phones is exploited by the agents that are running in mobile phones to discover danger c...

objective: better understanding of the furcation anatomy may serve to decrease the risk of root perforation. the purpose of this study was to measure the thickness of root walls in the danger zone in mandibular first molars. materials and methods: the roots of 53 extracted human mandibular first molars were sectioned in the horizontal plane 4 mm below the orifice of the mesial and distal root c...
