Recent times have seen a wide ranging and large scale use of paper as a potential material in sensors for determining the concentration of an analyte upon appropriate end-point development. Today's clinical, food and environmental sectors require low-cost practical analytical devices which are portable and offer on-site real time detection. We present a novel technique for estimating any analyte's concentration using a mobile app that analyses the image of the paper subsequent to a chromogenic assay. Making use of snakuscules for capturing the region of interest in the image, followed by basic strategies for removing illumination artifacts using the Von-Kries Coefficient Law, we correlated the luminosity of the colour developed on the paper strip against the analyte's concentration. We evaluate our algorithm by determining the glucose concentration levels in blood using commercially available glucometer strips using image processing and comparing them with actual glucose levels as estimated by auto analyzers. The results obtained correlated well with the conventional assay and were almost indistinguishable from the actual values. © 2014 IEEE. Source

In this article, the author will summarize and review Heinrich's work originally published in 1931. The author will then supplement that original work with accident data collected and compiled by the United States Bureau of Labor Statistics over a recent 17-year period. This additional data will then be used to expand the top layer of Heinrich's Triangle to include accidents resulting in OSHA recordable cases, lost workday cases, and fatalities. The result will be an updated version of Heinrich's Triangle consisting of five levels instead of the original three. These will start at the top with accidents resulting in fatalities and work down through lost workday cases, OSHA recordable incidents and first-aid cases to accidents with no injuries. Analysis of this additional data will lead to some interesting and significant conclusions about the validity of the underlying data. © 2010 American Institute of Chemical Engineers. Source

A 62-year-old woman with advanced cancer was admitted to the hospital experiencing inadequate pain control. Underdosing of opiates resulted from the persistent and inappropriate labeling of her behavior as drug-seeking, and the medical staff expressed discomfort about the administration of high doses of opiates. Palliative care personnel achieved better symptom control by the use of more confident and more liberal opiate dosing. The patient's quality of life improved immensely without adverse effects. We investigated reasons that account for the widespread practice of opiate underdosing. These include biases such as opiophobia - often unspoken and sometimes unrecognized. We share these insights to enhance the practice of others. Source

As businesses in the "Goods Producing" sector moved their operations outside of the United States over the last several decades, relatively higher accident rates went with them. The net result has been a trend towards business types, mostly in the "Service Providing" sector, which have historically lower accident rates. In this article, the author will show that a significant portion of the reductions in fatal occupational accidents over the 16-year span from 1992 to 2008 in the United States were the result of business trends away from the "Goods Producing" sector towards the "Service Providing" sector. This is not to say that improvements in accident prevention policies and procedures were not a major contributor to reductions in fatal occupational accidents as well. Instead, these policy and program improvements were augmented by the changing distribution of business types in the United States. The net result was a reduction in overall fatal occupational accident rates of~ 435% with ~ 23% of this reduction resulting from the changing distribution of business types in the United States. With the limited analysis demonstrated in this article, it is not possible to infer this same effect for other spans of time. It seems likely, however, that any span of years that sees a decrease in the percentage of hours worked in "Goods Producing" sector with a corresponding increase in the percentage of hours worked in "Service Providing" sector would have a decrease in total fatal accidents attributable only to the changing distribution of business types in the United States. © 2010 American Institute of Chemical Engineers.

The current study used the Medicare Current Beneficiary Survey-Based (MCBS) Cost and Use files for 2006-2008 to investigate whether health care costs and service utilization of nursing home residents varied with nurse practitioner (NP) and physician assistant (PA) involvement, compared to the use of medical doctors (MDs) only. The sample included Medicare beneficiaries 65 and older residing in a nursing home for the entire study year (433 annual observations). A generalized estimating equations procedure was used to assess whether health care cost and utilization measures varied by cohort. Point estimates indicated that the annual per-person cost of non-institutional services (total medical cost less the cost of the nursing home itself) was $3,847 and $3,170 more for individuals in the MD-only and MD-dominant cohorts, respectively, compared to those in the NP/PA-dominant cohort. © SLACK Incorporated.
