    Notizen: CuS, or covellite (hexagonal symmetry), was compressed in a diamond anvil cell at room temperature up to a pressure of 45 GPa, and studied using x rays from both a Mo Kα source and a synchrotron. The x-ray diffraction spectrum of CuS disappears by about 18 GPa. The presence of Cu fluorescence lines in all spectra and the reappearance of diffraction lines upon decompression confirm that CuS undergoes reversible pressure-induced amorphization at this pressure. A third-order Birch–Murnaghan equation of state fit to the diffraction data below 11 GPa yields a bulk modulus of 89±10 GPa with a pressure derivative of −2±2 for covellite. Further compression up to 45 GPa shows three to four diffraction lines of very low intensity, implying some high pressure "ordering'' of the amorphous phase. The Raman spectra obtained indicate that the changes in structure are probably due to the twisting or the distortion of covalently bonded CuS4–CuS4 units in different directions. © 1996 American Institute of Physics.

    Notizen: Corporate parents have the potential to add value to their businesses through their influence on the stand-alone performance of the businesses, but for a variety of reasons, including what we call the 10% versus 100% paradox, they more often destroy value instead. This article examines four companies, Dover, BTR, Emerson and RTZ, which succeed in creating value through stand-alone parenting influence, and draws out the conditions necessary to do so. These are that (1) there should be a genuine parenting opportunity to improve the performance of the business, (2) the parent should have skills, management processes, and other characteristics that are suitable for realising the opportunity, and (3) the parent should have sufficient feel for the critical success factors in the business to avoid inadvertently destroying value through inappropriate influences.

    Notizen: The U.S. Nuclear Regulatory Commission (NRC) staff has developed a performance assessment capability to address three programmatic areas in nuclear waste management: high-level waste, low-level waste, and decommissioning of licensed facilities (license termination). The NRC capability consists of (1) methodologies for performance assessment; (2) models and computer codes for estimating system performance; (3) regulatory guidance in various forms, such as regulations, Branch Technical Positions, and Standard Review Plans; and (4) a technical staff experienced in executing and evaluating performance assessments for a variety of waste systems. Although the tools and techniques are refined for each programmatic area, general approaches and similar issues are encountered in all areas.

    Notizen: Purpose - Managers need research-based guidance on how to find sources of new growth when their core business is maturing. Design/methodology/approach - Authors shadowed managers responsible for finding and entering new businesses, interviewing them every three or four months for an average of two years. They surveyed over 100 corporate venturing units and corporate incubators and assembled a database of over 50 stories of companies that had successfully developed or acquired a significant new business. We interviewed managers in about half of these companies that had successfully diversified and we tested our emerging hypotheses against this database. Findings - All research indicated that managers need to assess opportunities more strategically and be less activity driven. The authors concluded that managers were investing in too many projects, most of which had little chance of success. Research limitations/implications - If research is reported on in the paper this section must be completed and should include suggestions for future research and any identified limitations in the research process. Practical implications - Ashridge Strategic Management Centre has developed a screening tool - The New Businesses Traffic Lights to test opportunities before a business plan has been developed, alongside a business plan to assess the strategic logic for the proposal, or to an existing investment that is failing to meet its short-term targets. Originality/value - Applying the screen to the portfolio of new business investments in most companies will result in red lights for many projects. Not only can significant money be saved from the "new businesses" budget, but also extra resources can be focused on improving the core businesses.

    Notizen: Abstract. Over the past several years there has been a considerable amount of research within the field of quality-of-service (QoS) support for distributed multimedia systems. To date, most of the work has been within the context of individual architectural layers such as the distributed system platform, operating system, transport subsystem and network layers. Much less progress has been made in addressing the issue of overall end-to-end support for multimedia communications. In recognition of this, a number of research teams have proposed the development of QoS architectures which incorporate QoS-configurable interfaces and QoS driven control and management mechanisms across all architectural layers. This paper examines the state-of-the-art in the development of QoS architectures. The approach taken is to present QoS terminology and a generalized QoS framework for understanding and discussing QoS in the context of distributed multimedia systems. Following this, we evaluate a number of QoS architectures that have emerged in the literature.

    Notizen: Abstract. Distributed audio and video applications need to adapt to fluctuations in delivered quality of service (QoS). By trading off temporal and spatial quality to available bandwidth, or manipulating the playout time of continuous media in response to variation in delay, audio and video flows can be made to adapt to fluctuating QoS with minimal perceptual distortion. In this paper, we extend our previous work on a QoS Architecture (QoS-A) by populating the QoS management planes of our architecture with a framework for the control and management of multilayer coded flows operating in heterogeneous multimedia networking environments. Two key techniques are proposed: i) an end-to-end rate-shaping scheme which adapts the rate of MPEG-coded flows to the available network resources while minimizing the distortion observed at the receiver; and ii) an adaptive network service, which offers “hard” guarantees to the base layer of multilayer coded flows and “fairness” guarantees to the enhancement layers based on a bandwidth allocation technique called Weighted Fair Sharing.
