This study indicates that the performance incentives increase individuals' desire for money and inculcate materialism in individuals' expose to them. Sales agents from different companies were taken as a sample, where half of the agents were getting fixed pay and half were getting Performance-based pay. The required data was collected through survey questionnaires. Two scales, i.e., material values scale and desire for money, were used to collect the data. Analysis was done applying linear regression analysis. The results showed that the desire for money and materialism increases in individuals through the administration of performance incentives. Next, the two groups of sales agents were compared, which showed a greater desire for money and materialism in performance-based sales persons as compared to individuals who were getting fixed pay.
Stegnography is the process of hiding one file inside another such that others can neither identify the meaning of the embedded object, nor even recognize its existence. Current trends favour using digital image files as the cover file to hide another digital file that contains the message or information. One of the most common methods of implementation is Least Significant Bit Insertion. This paper is an attempt to introduce an algorithm which uses LSB Stegnography as the basis and randomly disperses the secret message over the entire image to ensure that the message cannot be obtained easily from the image.

Introduction: As the availability and use of medical imaging has increased, ionizing radiation has become a significant occupational exposure. Staff in the cardiac catheterization laboratory are among those with the highest exposures. Hypothesis: Changing equipment defaults to decrease patient radiation exposure would also decrease staff radiation exposure. Methods: In October 2013 we made equipment adjustments to decrease patient radiation exposure in all 3 cardiac catheterization laboratories at Eastern Maine Medical Center. We changed fluoroscopy defaults to low dose option and low frame rate (7.5 frames/sec from 15 frames/sec) while maintaining the option for operators to use higher settings as needed. We analyzed staff radiation exposure for 8 physicians and 14 nurses by comparing total collar dosimeter dose (in mRem) between the 3 months before and 3 months after the intervention controlling for procedural volume using standard statistical methods. Results: For physician operators, mean dosimeter dose decreased by 41.6% (346.8 ± 264.8 pre vs 202.5 ± 135.9 post intervention, p=0.042). For nurses whose roles are to assist during procedures or to circulate in the room, the mean dosimeter dose decreased by 25% (65.9 ± 49.4 pre vs 50.2 ± 53.5 post intervention, p=0.038). There was no significant difference between the number of cases performed by physicians (p=0.598) and nurses (p= 0.866) before and after the intervention. Procedural success did not decline post-intervention. Compliance with wearing collar dosimeter is required and reported as excellent at our institution. Conclusions: Setting fluoroscopy defaults to low dose and low frame rate to improve patient radiation exposure also significantly decreased radiation exposure for both physician and ancillary staff working in the cardiac catheterization laboratory. If widely adopted this intervention would help to mitigate the long term adverse effects of occupational exposure to ionizing radiation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
