Deutsche Telekom and Voicestream Merger: Charting a New Regulatory Course

On July 24, 2000, the German telecommunications giant Deutsche Telekom AG (Deutche Telekom) agreed to purchase the Bellvue, Washington based VoiceStream Wireless Corporation (VoiceStream) for over $50 billion. Although the merger may ultimately fall through, the response generated by the proposed merger indicates the future for deals between US and foreign-owned telecommunications companies. With the increasing globalization of the world\u27s telecommunications markets, the Deutche Telekom deal represents the first time that a company dominated by a foreign government has attempted to purchase an American corporation.

An analysis of choice making in the assessment of young children with severe behavior problems.

We examined how positive and negative reinforcement influenced time allocation, occurrence of problem behavior, and completion of parent instructions during a concurrent choice assessment with 2 preschool-aged children who displayed severe problem behavior in their homes. The children were given a series of concurrent choice options that varied availability of parent attention, access to preferred toys, and presentation of parent instructions. The results showed that both children consistently allocated their time to choice areas that included parent attention when no instructions were presented. When parent attention choice areas included the presentation of instructions, the children displayed differential patterns of behavior that appeared to be influenced by the presence or absence of preferred toys. The results extended previous applications of reinforcer assessment procedures by analyzing the relative influence of both positive and negative reinforcement within a concurrent-operants paradigm
