In 2012, the Office of the National Coordinator for Health Information Technology (ONC) conducted a nationally representative telephone survey of 2,050 adult individuals, in both English and Spanish. The survey focused on their privacy and security attitudes, in particular when their health information is stored or transmitted electronically via EHRs and HIE. This data brief reports individuals perceptions about the measures put in place by providers to protect EHRs, and its association with support for EHRs, HIE and patient-provider communication.

The report presents the results of a survey of safety culture in three Norwegian haulier companies, which are selected based on an assumption that they have good safety culture. The study supports the assertion that the companies have good safety cultures. This especially applies to Company A, which has the highest safety culture score of the three companies, and which also have a higher safety culture score than we have found in other transport sectors. This is probably due to the fact that Company A transports dangerous goods, which is a line of transport which has particular framework conditions favoring safety. The accident involvement of the drivers were in accordance with the companies score on the safety culture index. Analyzing the data on the three companies work on safety, we have identified the following common characteristics of good safety work in haulier companies: 1) Follow up of drivers speed, seat belt use and driving style, 2) Managers and employees safety commitment, 3) Predictability, 4) Organization of transport assignments, 5) Pay system, 6) Control of drivers compliance with regulations related to drive and rest, 7) Safety training/education, 8) Arenas for communication about safety, 9) Reporting culture and systems, and 10) Safety management system: a) risk analyses, b) procedures, c) training.

Mobile devices provide civilians with a convenient way to communicate on a day-to-day basis. However, their centralized infrastructure can be interrupted at critical times such as during natural disasters. While this cellular infrastructure may not be available in environments, such as the battlefield, these ubiquitous devices could exploit ad-hoc mode communication to be of use. The Army has identified several military applications for ad-hoc networks of mobile devices, including communication between dismounted Soldiers, facial recognition, and situation awareness. Many of these applications require more capabilities than most mobile devices possess, or would prove to be a burden on the limited battery lives of these devices. Thus, offloading computation to a more capable machine has been identified as a means to make these devices useful while mitigating their weaknesses. This has lead Army researchers to develop novel algorithms to improve the offloading process. Although these algorithms have been tested via simulation, a working implementation is necessary to fully evaluate them. This report discusses the state of ad-hoc mode communication on Android devices, and describes the procedure for enabling ad-hoc mode, which is often not available by default. It goes on to describe techniques for studying multiple aspects of the network and its behavior.

We generate high-purity correlated and entangled photon- pairs at the telecom wavelengths in a cooled 10-meter highly nonlinear fiber (HNLF). In our previous project (contract no: FA8750-12-1-0136), we were able to generate correlated/entangled photon-pair using the highly nonlinear fiber in a counter-propagating scheme (CPS). With the HNLF at room temperature, we obtain coincidence-to-accidental ratio (CAR) approximately 26-30 and two-photon interference with visibility approximately 92-93. This is the best performance compared to the reported results in the literature on HNLF and Photonic Crystal Fiber (PCF) at telecom wavelengths. Unlike the PCF or microstructure fiber, the HNLF can be cooled at liquid nitrogen temperatures (77K) to suppress Raman photons. By cooling the HNLF, we expect to obtain a CAR approximately 130 and two-photon interference with visibility > 98. We will verify the non-local behavior of high-purity HNLF-based entangled photon-pairs by making Bell's Inequalities measurements. We investigate the effect of multiple scattering on the telecom wavelength photon-pair. Our findings show that quantum correlation of polarization-entangled photon-pairs is better preserved than polarization-correlated photon-pairs in multiple scattering processes.

Over the past decade, several technological advances have allowed Global Navigation Satellite Systems (GNSS) receivers to have the capability to record displacements at high frequencies, with sampling rates approaching 100 samples per second (sps). In addition, communication and computer hardware and software have allowed various institutions, including the U.S. Geological Survey (USGS), to retrieve, process, and display position changes recorded by a network of GNSS sites with small, less than 1-s delays between the time that the GNSS receiver records signals from a constellation of satellites and the time that the position is estimated (a method known as real-time). These improvements in hardware and software have allowed the USGS to process GNSS (or a subset of the GNSS, the Global Positioning System, GPS) data in real-time at 1 sps with the goal of determining displacements from earthquakes and volcanoes in real-time. However, the current set of GNSS equipment can record at rates of 100 sps, which allows the possibility of using this equipment to record earthquake displacements over the full range of frequencies that typically are recorded by acceleration and velocity transducers. The advantage of using GNSS to record earthquakes is that the displacement, rather than acceleration or velocity, is recorded, and for large earthquakes, the GNSS sensor stays on scale and will not distort the observations due to clipping of the signal at its highest amplitude. The direct observation of displacement is advantageous in estimating the size and spatial extent of the earthquake rupture. Otherwise, when using velocity or acceleration sensors, the displacements are determined by numerical integration of the observations, which can introduce significant uncertainty in the estimated displacements.

The global positioning system (GPS) market is a fast changing, highly competitive market. Products change frequently as they try to provide the best customer experience for a service that is based on the need for real-time data. Two major functions of the GPS unit are to correctly report traffic jams on a drivers route and provide an accurate and timely estimated time of arrival (ETA) for the driver whether he/she is in a traffic jam or just following driving directions from a GPS unit. This study measures the accuracy of traffic jam reporting by having Personal Navigational Devices (PNDs) from TomTom and Garmin and phone apps from TomTom, INRIX, and Google in the same vehicle programmed to arrive at the same destination. We found significant differences between the units in terms of their ability to recognize an upcoming traffic jam. We also found differences in how well the devices responded to jams when driving on surface streets versus highways, and whether the jams were shorter or longer in length. We see potential for auto manufacturers to employ real-time traffic in their new vehicles, providing potential growth for real-time traffic providers through access to new vehicles as well as the aftermarket.
