Electron diffraction intensities can be obtained at large scattering angles (sinθ/λ ≥ 2.0), and thus structure information can be collected in regions of reciprocal space that are not accessable with other diffraction methods. LACBED intensities in this range can be utilized for determination of accurate temperature factors or for refinement of coordinates. Such high index reflections can usually be treated kinematically or as a pertubed two-beam case. Application to Y Ba2Cu3O7 shows that a least square refinememt based on integrated intensities can determine temperature factors or coordinates.LACBED patterns taken in the (00l) systematic row show an easily recognisable pattern of narrow bands from reflections in the range 15 < l < 40 (figure 1). Integrated intensities obtained from measured intensity profiles after subtraction of inelastic background (figure 2) were used in the least square fit for determination of temperature factors and refinement of z-coordinates for the Ba- and Cu-atoms.

This paper presents a survey of Assurance Case implementation for applications which are not directly related to the usual for Assurance Case regulatory regime. The UK is the country which first developed the theory of Assurance Case as a response to big catastrophes, and most applies Assurance Case regime for many industrial domains. USA, Australia and EU countries apply Assurance Case approach for safety and security regulation and licensing. For the last two decades Assurance Case has been used mostly for confirmation analysis of critical systems with established set of regulatory requirements. There are proven standards of use, notations and tools to support Assurance Case methodology. However, many researchers have tried to find approach to expand Assurance Case application to communicating domains. We group the following directions of Assurance Case applications as the following ones: Assurance Case for attributes assessment such as quality, dependability and, first of all, safety and security, Assurance Case based certification, improvement of argumentation, assurance based development, and Assurance Case for knowledge management. The main challenges and solutions of development and application of Assurance Case methodology, techniques and tools have been analyzed.

More than 150 years into development of the doctrine of "fair use" in American copyright law, there is no end to legislative, judicial, and academic efforts to rationalize the doctrine. Its codification in the 1976 Copyright Act appears to have contributed to its fragmentation, rather than to its coherence. This Article suggests that fair use is neither badly conceived nor badly applied, but that it is too often badly understood. As did much of copyright law, fair use originated as a judicially-unacknowledged effort via the law to validate certain favored social practices and patterns. In the main, it has continued to be applied as such, though too often courts mask their implicit validation of these patterns in the now-conventional "case-by-case" application of the statutory fair use "factors" to the defendant's use of the copyrighted work in question. A more explicit acknowledgement of the role of these patterns in fair use analysis is consistent with fair use and copyright policy and tradition. Importantly, it helps to bridge the often-difficult conceptual gap between fair use claims asserted by individual defendants and the social implications of accepting or rejecting those claims. Finally, a pattern-oriented approach is normatively appropriate, when viewed in light of recent research by cognitive psychologists and other social scientists on patterns and creativity. In immediate terms, the approach should lead to a more consistent and predictable fair use jurisprudence. In the longer term, it should enhance the ability of copyright law to promote creative expression.
