It's commendable that you?re committed to using protection! You ask two very good questions. First, who puts it on? That's completely up to you and your partner and either of you can take the lead on this one. Some people prefer to put the condom on themselves, while others find it sexy and enjoyable when their partners do it for them. This action can be incorporated into foreplay and is loaded...

A quasi-passive leg exoskeleton is presented for load-carrying augmentation during walking. The exoskeleton has no actuators, only ankle and hip springs and a knee variabledamper. Without a payload, the exoskeleton weighs 11.7 kg and requires only 2 Watts of electrical power during loaded walking. For a 36 kg payload, we demonstrate that the quasi-passive exoskeleton transfers on average 80% of...

End-to-end integrity for documents is provided by wrapping the tools that manipulate those documents and mediating their operation to cryptographically integrity mark those documents as they are being saved, to check those cryptographic integrity marks as those documents are loaded, and to record an application-level history of the changes to the document. Corrupted documents (those failing to ...

It has often been shown that the amount of media use is negatively related to cognitive outcomes. The more time spent on media the poorer cognitive performance is. This association has mainly been found for general-audience, violent, and action-loaded contents but not for educational contents. Typically, long-term-explanations like the time-displacement hypothesis are considered to account for ...

We investigate the role of framing, inequity in initial endowments and history in shaping behavior in a corrupt transaction by extending the one-shot bribery game introduced by Cameron et al. (2009) to a repeated game setting. We find that the use of loaded language significantly reduces the incidence of bribery and increases the level of punishment. Punishment of bribery leads to reduced bribe...

Escalators are a common method of transportation for people in commercial and residential buildings, for this reason its energy efficiency is usually a matter of concern. Typically, the design of energy saving systems to be used in them involves the control of their speed. In this situation, in order to estimate the achievable energy savings it is necessary to evaluate the escalator’s behaviour...

We study a setting in which a principal contracts with an agent to operate a firm over an infinite time horizon when the agent is liquidity constrained and privately observes the sequence of cost realizations. We formulate the principal’s problem as a dynamic program in which the state variable is the agent’s continuation utility, which is naturally interpreted as his equity in the firm. The op...

Assuming that a material point becomes unstable when the e€ective plastic strain there reaches a critical value, it is found that a material instability will initiate at a point on the crack-tip of an impulsively loaded prenotched plate that makes an angle of )14° to the notch-tip. This agrees well with the observed values of )5° to )15°. Ó 1998 Elsevier Science Ltd. All rights reserved.

Suppose m balls are sequentially thrown into n bins where each ball goes into a random bin. It is well-known that the gap between the load of the most loaded bin and the average is Θ( √ m logn n ), for large m. If each ball goes to the lesser loaded of two random bins, this gap dramatically reduces to Θ(log logn) independent of m. Consider now the following “(1 + β)-choice” process for some par...
