Multipurpose Iron Man Glove & Moveable Platform

The multipurpose glove is a hand-worn device that wirelessly controls the position of a platform and flashes a high power LED at a particular frequency in order to alias the motion of an oscillatory object. The position and motion of the platform is dictated by an accelerometer which is attached to the top of the glove, as shown in Fig. 1. The user can then tilt the hand forward, backward, left, or right, to cause the platform to move towards a desired location. The user can also adjust the flashing frequency of the high power LED that is attached to the bottom of the glove. This frequency adjustment can be done through hand motion and the accelerometer, or by changing the position of a potentiometer that is attached to the overall casing, as depicted by Fig. 1. Figure 1 also displays the battery armature, which is used to fix the battery and secure the system casing around the forearm of the user with VELCRO straps

Parenting and digital media: from the early days of the web to contemporary digital society.

Parents have accessed websites, online discussion forums and blogs for advice, information and support since the early days of the World Wide Web. In this article, we review the literature in sociology and related social research addressing the ways in which digital media have been used for parenting-related purposes. We begin with the longer-established media of parenting websites, online discussion forums, blogs, email, mobile phones and message and video services and then move on to the newer technologies of social media and apps. This is followed by a section on data privacy and security issues. The concluding section summarises some major issues arising from the review and points to directions for further research

Dynamic Security Design

We analyse dynamic financial contracting under moral hazard. The ability to rely on future rewards relaxes the tension between incentive and participation constraints, relative to the static case. Managers are incited by the promise of future payments after several successes and the threat of liquidation after several failures. The more severe the moral hazard problem, the greater the liquidation risk. The optimal contract can be implemented by holding cash reserves and by issuing debt and equity. The firm is liquidated when it runs out of cash. Dividends are paid only when accumulated earnings reach a certain threshold. In the continuous time limit of the model, stocks follow a diffusion process, with a stochastic volatility that increases after price drops. In line with empirical findings, performance shocks induce long lasting changes in leverage.asset pricing; Dynamic Financial Contracting; moral hazard; security design
