This paper analyzes the use of alternative performance measures in an agency model in which contracting incorporates both formal and informal agreements. It is shown that under a proper use of verifiable and unverifiable performance measures, the two types of contracts are complements, regardless of the principal’s fallback position. The analysis therefore contrasts earlier results of the liter...

Phosphate esters in polyhydroxylated systems are normally blighted by uncontrolled migration under a variety of reaction conditions. Cesium fluoride is demonstrated as a reagent to control migration of primary phosphates during transesterifications. This allows easy exchange of phosphoryl protecting groups enabling enhanced synthetic strategic flexibility and regioselective phosphate installati...

Haptic interfaces using active force-feedback have mostly been used for emulating existing instruments and making conventional music. With the right speed, force, precision and software they can also be used to make new sounds and perhaps new music. The requirements are local microprocessors (for low-latency and high update rates), strategic sensors (for force as well as position), and non-line...

We introduce a Security Game with a single static guard that is supported by a number of spatially imperfect alarms. We model this setting with two non–cooperative games modeling two different strategic interactions between a Defender and an Attacker. In the first one the Defender has to respond to an activated alarm given its current position (Alarm–Response Game). In the second one, the Defen...

UNLABELLED Cardiac myxomas are histologically benign tumors but they may be lethal because of their strategic position. They have variable presentations and excellent prognosis after surgical excision. Left atrial myxomas may mimic mitral stenosis and is very rarely associated with pleural effusion. We presented a case of left atrial myxoma blocking mitral orifice and causing recurrent pulmonar...

In the course of this paper, a by IFEN GmbH developed integrated navigation device for aiding and rescuing fire fighters in emergency situations is presented. In areas with sufficient signal strength the respective rescue force is tracked by means of GNSS/INS position information, whereas indoor or in areas without GNSS support, the positioning is conducted by means of a foot mounted inertial m...

One of the central activities in developing requirements for business processes is that of modelling the constituent parts of both existing and future processes. This position paper examines requirements engineering issues for business processes in terms of the nature of the problem domain and of the development activities. The paper proposes a modelling framework which, in addition to the trad...

There is a growing interest in intraand interorganizational network dynamics. The central question in the latter domain is, ‘‘How do firms choose collaborative partners given their present network configuration, their goals, and characteristics, to get a strategic network position?’’ We introduce actor-oriented network models as a method to describe and explain the development of interorganizat...

ince 1992, the Strategic Systems Department of the Applied Physics Laboratory has been investigating the use of high-frequency (HF) ground wave transmissions in the upper HF band for sea-based communications. This effort has examined the optimization of shipboard antennas for two-way communications with ground stations. This article describes early tests using differential Global Positioning Sy...

SCAI is embarking on a new strategic planning process. Its goal is to determine the course SCAI should take over the next 3-5 years, and to position SCAI, its members and their patients for continued success in coming decades. Put simply, we are aiming for both longand short-term success. During the past several months SCAI leaders and staff have sought input from members, other societies, indu...
