Stents, Stents, Everywhere - Now Even in the BRAIN! - Anesthesia Patient Safety Foundation
Myocardial stents (both bare metal and drug-eluting varieties) are widely utilized to prevent restenosis following percutaneous transluminal coronary angioplasty (PTCA) and coronary intervention (PCI). Indeed, by 1999 myocardial stents were...
Micromachines | Free Full-Text | WiFi-Aided Magnetic Matching for Indoor Navigation with Consumer Portable Devices | HTML
This paper presents a WiFi-aided magnetic matching (MM) algorithm for indoor pedestrian navigation with consumer portable devices. This algorithm reduces both the mismatching rate (i.e., the rate of matching to an incorrect point that is more than 20 m away from the true value) and computational load of MM by using WiFi positioning solutions to limit the MM search space. Walking tests with Samsung Galaxy S3 and S4 smartphones in two different indoor environments (i.e., Environment #1 with abundant WiFi APs and significant magnetic features, and Environment #2 with less WiFi and magnetic information) were conducted to evaluate the proposed algorithm. It was found that WiFi fingerprinting accuracy is related to the signal distributions. MM provided results with small fluctuations but had a significant mismatch rate; when aided by WiFi, MM’s robustness was significantly improved. The outcome of this research indicates that WiFi and MM have complementary characteristics as the former is a point-by-point matching approach and the latter is based on profile-matching. Furthermore, performance improvement through integrating WiFi and MM depends on the environment (e.g., the signal distributions of magnetic intensity and WiFi RSS): In Environment #1 tests, WiFi-aided MM and WiFi provided similar results; in Environment #2 tests, the former was approximately 41.6% better. Our results supported that the WiFi-aided MM algorithm provided more reliable solutions than both WiFi and MM in the areas that have poor WiFi signal distribution or indistinctive magnetic-gradient features.
Gambling as social practice: a complementary approach for reducing harm? | Harm Reduction Journal | Full Text
Background Gambling is now a well-recognised public health issue and forms the focus of extensive harm reduction initiatives. Recent developments in policy, practice and technology, such relaxation of regulations, the increasing influence of global gambling corporations, and the development of devices such as mobile phone apps and fixed odds betting terminals (FOBTs) mean that the landscape is a complex, dynamic, and fast moving one. Gambling is now practiced using new technologies, in various spaces and places, and features in a range of social surroundings. Therefore, research is needed to inform appropriate gambling harm reduction strategies that can respond to this complex domain. Yet, research and policy approaches to the reduction of gambling harm are predominantly framed through psychological and economic models of individual behaviour, addiction, and ‘rational’ action. This is beginning to change, with a growing corpus of socio-cultural approaches to gambling research now emerging. Method In this article, we argue the case of recognising gambling as a social practice, the performance of which draws upon multiple elements such as technology and materials, spaces and places, language and discourse, and structures and agency. We call for a practice theory approach to gambling research that joins efforts to move beyond individual gamblers and their behaviour, to also acknowledge the interaction of multiple elements shaping gambling practices. To achieve this, we suggest that research methods such as visual ethnography can be helpful. Conclusion We set out how a social practice perspective to gambling research can generate different insights and help inform more nuanced and appropriate gambling harm reduction initiatives.

Executives routinely dose their organizations with strategic snake oil: discredited nostrums, partial remedies, or untested management miracle cures. In many cases, the facts about what works are out there—so why don’t managers use them?
