We investigate how an entrepreneur's behaviors during an initial interaction with a business angel can build, damage, or violate trust, and how the investor's level of trust (prompted by the entrepreneur's behavior) can affect his/her decision to make an investment offer. Our empirical analysis shows that entrepreneurs who receive offers from business angels exhibit a larger number of trust–building behaviors during the initial interaction and a smaller number of unintentional trust–damaging behaviors than those who do not receive an offer, and display few deliberate trust–violating behaviors. We further observe that the investor's deployment of a control mechanism is a prerequisite for receiving an investment offer for all entrepreneurs who damage or violate trust.

Remote access laboratories (RALs) are online environments for operating instruments and collecting measurement data over the Internet. Such systems are often deployed by universities to support undergraduate students and generally follow the client-server paradigm. This paper discusses a RAL system that enables peer-to-peer (P2P) experimental design and sharing. For this, a modular design is required, which allows participating nodes to create rigs and host those individually at distributed locations. The proposed architecture is generic and can be used with any distributed P2P network control systems over the Internet. In this paper, a distributed remote control framework is presented with regard to a P2P RAL system. The experiments in the RAL require three subsystems handling the user interface, instruction interpretation, and instruction execution which can be organized and operated in different manners depending upon the experiment. The key component for creating and controlling experiments is the microcontrollers that can be easily obtained, configured, and set up for use over the Internet. The most popular microcontrollers are examined for suitability to the distributed control architecture. The basic layout of a message-based network protocol suitable for programming the devices and communication between peers for remote instrumentation and control is discussed, and queuing and flow control mechanisms are compared and tested for the proposed framework.Index Terms-Message-oriented middleware, microcontrollers, networking, remote laboratories, web instrumentation. 0278-0046
