in march 2004, a fluxgate gradiometer survey was conducted over tepe ghabristan, covering approximately 6ha of ground. it identified further areas of the iron age cemetery with possible grave pits (areas b and c). in addition, an irrigation channel was discovered which could be contemporary to these iron age graves (area d). the anomalies in area e can be interpreted as buried structural remain...

INTRODUCTION Response rates for the Behavioral Risk Factor Surveillance System (BRFSS) have declined in recent years. The response rate in 1993 was approximately 72%; in 2006, the response rate was approximately 51%. To assess the impact of this decline on the quality of BRFSS estimates, we compared selected health and risk factor estimates from BRFSS with similar estimates from the National He...

OBJECTIVE The goal of this research was to identify the fraction of deaths attributable to diabetes in the United States. RESEARCH DESIGN AND METHODS We estimated population attributable fractions (PAF) for cohorts aged 30-84 who were surveyed in the National Health Interview Survey (NHIS) between 1997 and 2009 (N = 282,322) and in the National Health and Nutrition Examination Survey (NHANES)...

Background. There are limited research and substantial uncertainty about the level of eye care utilization in the United States. Objectives. Our study estimated eye care utilization using, to our knowledge, every known nationally representative, publicly available database with information on office-based optometry or ophthalmology services. Research Design. We analyzed the following national d...

BACKGROUND Little is known regarding the epidemiology of chronic rhinosinusitis (CRS) in racial and ethnic minorities in the United States. This study was designed to comprehensively evaluate the current prevalence of CRS across various treatment settings to identify possible disparities in health care access and use between racial and ethnic populations. METHODS The National Health Intervie...

Using the advances in computing power, software and hardware technologies, virtual reality (VR), and gaming applications have the potential to address clinical challenges for a range of disabilities. VR-based games can potentially provide the ability to assess and augment cognitive and motor rehabilitation under a range of stimulus conditions that are not easily controllable and quantifiable in...

In this paper we present the results of a study to determine the effect and efficacy of a Virtual Reality game designed to elicit movements of the upper extremity. The study is part of an on-going research effort to explore the use of Virtual Reality as a means of improving the effectiveness of therapy for children with motor impairments. The current study addresses the following questions: 1. ...

We show that reputational effects may explain differences in economic performances of dictatorial or authoritarian governments. A good reputation convinces citizens that the dictator will exert high effort in economic performance. With replacement, a dictator exerts high effort only if its foregone rent is not too large. Without replacement, the dictator succeeds in convincing the citizens of i...

It was an observational, prospective cohort study at 13 maxillofacial clinics in the United Kingdom. METHODS The 131 patients comprised 47 males (35.9%) and 84 females (64.1%), with an average age of 22.6 years. They received orthodontic/...

Virtual reality (VR) surgery simulation is an emerging teaching tool to train residents in cataract surgery. The widespread adoption of virtual surgery has been limited, however, by high costs and the absence of standardized curricula and evidence demonstrating the impact of VR training on resident surgical outcomes. We outline a resident virtual cataract surgery course--freely accessible onlin...
