    Financial derivatives allow users to manage or hedge certain business risks that arise from volatile commodity prices, interest rates, foreign currencies, and a wide range of other variables. Derivatives also permit potentially risky speculation on future trends in those rates and prices. Derivatives markets are very large—measured in the hundreds of trillions of dollars—and they grew rapidly in the years before the recent financial crisis. The events of the crisis have sparked calls for fundamental reform. ... This report analyzes the issues of derivatives clearing and margin and end users, and it discusses the various legislative approaches to the enduser issue.

    A break from pain! Interruption management in the context of pain

    Get PDF
    Activity interruptions, namely temporary suspensions of an ongoing task with the intention to resume it later, are common in pain. First, pain is a threat signal that urges us to interrupt ongoing activities in order to manage the pain and its cause. Second, activity interruptions are used in chronic pain management. However, activity interruptions by pain may carry costs for activity performance. These costs have recently started to be systematically investigated. We review the evidence on the consequences of activity interruptions by pain for the performance of the interrupted activity. Further, inspired by literature on interruptions from other research fields, we suggest ways to improve interruption management in the field of pain, and provide a future research agenda

Advances of technology electronics helped in the development of better security systems. One of application is the security system used for safety locker locks using RFID card and password. The safety lock on the locker door is designed by using a dual system that aims the doors of locker which can only be opened by using RFID card and password. RFID card locker serves as the identity and password as the electronic lock. Each RFID card have different id chips, so it is not easy to duplicate. The purpose of making this tool is to design and make a locker lock open or closes the door of locker automatically with access control using RFID card and password

    Effects of activity interruptions by pain on pattern of activity performance - an experimental investigation

    Get PDF
    Background and aims: Suspending an ongoing activity with the intention to resume it again later is a natural response to pain. This response facilitates coping with the pain, but it may also have negative consequences for the resumption and performance of the activity. For example, people with pain problems are often forced to take a break from doing their household chores because of their pain. They might delay resuming their chore, eventually needing longer time to finish it. We investigated how activity interruptions by pain influence the pattern of subsequent activity performance. We expected that when an activity is interrupted by pain (compared to non-pain), people spend longer time away from the activity, need longer time to complete it, and are less motivated to perform it. Methods: Sixty healthy volunteers performed an ongoing task that required them to make joystick movements in different directions according to a specific rule. Occasionally, participants received either a painful electrocutaneous stimulus or a non-painful and non-aversive auditory stimulus (between-subjects) as an interruption cue. The interruption cue was followed by the temporary suspension of the ongoing task and the initiation of a different activity (interruption task). The latter required the categorization of cards and had a maximum duration, but participants could also stop it earlier by pressing a button. We measured time away from the (interrupted) ongoing task, total time to complete the ongoing task (including the interruptions) and self-reported motivation to perform both the ongoing as well as the interruption task. Results: Groups did not differ in the time away from the ongoing task, total time to complete the ongoing task, or self-reported motivation to perform the two tasks. Conclusions: Activity interruptions by pain did not impair the pattern of activity performance more than activity interruptions by non-pain. Potential explanations and suggestions for future research are discussed
