The paper deals with changes in the sectorial structure of Czechoslovak economy with respect to development and changes in the geographical distribution of Czechoslovak industry in the period of 1962-1988 divided into three stages and with respect to broader historical context and changes after November 17th, 1989.

The digital and the related technological evolution in recent years have shifted to words such as Virtual Reality and Artificial Intelligence. The wider use of these and other technologies in architecture has been far limited by a lack of IT tools with which architects could interface since they have been made available in the last few years only. The evolution of the tools used by the architect can be condensed and simplified into a sequence of three stages: Drawing Board, CAD systems, Game Engines. The frames of this sequence, in addition to indicating instruments, are representative of the historical context in which they have been or are still being used. This study, based on a Master thesis recently discussed at the Politecnico di Milano [14], examines the role that Game Engines can play in the graphic representation and design processes. More specifically, it takes a closer look at the Unreal Engine as a tool for creating a real-time design environment and using Artificial Intelligence (AI) technologies to represent user flows in the space as valuable support and a relevant part of the design strategies aiming at implementing and evaluating design options. For this purpose, various simulations have been carried out both considering users' flows based on assigned spaces, and generating spaces based on the users' flows.

This article follows prevailing trends in research on the archival practices of the premodern Middle East by emphasizing the importance of documentary life cycles. Specifically, it examines the afterlives of a microsample of documents from an underexplored historical context: the administration of amirs who held iqṭāʿ land grants in areas of Egypt outside Cairo. Though iqṭāʿ holders (muqṭaʿs) were key administrative actors in the Mamluk sultanate, we know little about their activities on the ground. The material investigated here is related to the administration of justice in far-flung districts of Egypt, one of the less-known roles of these muqṭaʿs, and is preserved in the Papyrus Collection of the Austrian National Library in Vienna. Contextualizing the documents by relating them to the activities of several named amirs, I delineate three stages in the documents’ afterlives: archiving, reuse, and disposal. I rely on the materiality of the documents, an indispensable tool for identifying the more enigmatic aspects of documentary life cycles. I then turn to reflect on what these afterlives can tell us about the archival spaces of this administrative setting. By examining the muqṭaʿs’ paperwork, I highlight shifts in meaning that documents underwent over time, calling attention to the phenomenon of casual storage, or “documents lying around.”

The paradigm shifts from the 1950s to the 1980s in political science arebest explained with reference to the encounter with the Other, an encounterwhich has three stages: first, the self-confident representation of the Otherwhich is characteristic of modernity; second, the fear of and desire to controlthe Other which is characteristic of the end of modernity; and third, thehyperrealization and trivialization of the Other which is characteristic ofpostmodernity. This encounter with the Other takes place within a largerdiscourse context or episteme. The epistemic shifts, then, must also beconsidered.Paradigm ShiftFoucault’s concept of archaeology includes the idea that scientific systemsare valid within their own contexts. Thus each piece of historical data mustbe judged and assessed in its own stratum or context. In a less sophisticatedfashion, Kuhn has taken this idea of historical context and cultural relativismand come up with a theory of scientific revolution. Kuhn correctly identifiesthe science textbook genre as the received history of normal science, a genrewhich incorporates the myth of the steady cumulative process of science.The textbook mythology traces the history of great white men and greatexperiments as they contributed their energies to the irresistible march ofscientific progress. Kuhn demonstrates that Aristotelian dynamics or caloricthermodynamics are in fact internally systematic and scientific and are thereforejust as valid as contemporary dynamics or thermodynamics. In reference totheir “fit” with nature, an earth-centered astronomy is just as valid as a suncenteredastronomy. What happens is that when the questions change, andquestions are asked which strain an earth-centered astronomy, a paradigm ...

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.

The evolution of dislocation channels in irradiated metals during deformation can be envisaged to occur in three stages: (i) formation of embryonic cluster free regions, (ii) growth of these regions into microscopically observable channels and (iii) termination of their growth due to the accumulation of dislocation damage. The first two stages are particularly intriguing, and we have attempted to follow the early stages of channel formation in polycrystalline molybdenum, irradiated to 5×1019 n. cm−2 (E > 1 Mev) at the reactor ambient temperature (∼ 60°C), using transmission electron microscopy. The irradiated samples were strained, at room temperature, up to the macroscopic yield point.Figure 1 illustrates the early stages of channel formation. The observations suggest that the cluster free regions, such as A, B and C, form in isolated packets, which could subsequently link-up to evolve a channel.

The European Association of Psychologists’ Associations (EFPA) was created in 1981 as the European Association of Professional Psychologists’ Associations (EFPPA). We show that Shakespeare’s dictum “What’s in a name?” does not apply here and that the loss of the “first P” (the adjectival “professional”) was resisted for almost two decades and experienced by many as a serious loss. We recount some of the deliberations preceding the change and place these in a broader historical context by drawing parallels with similar developments elsewhere. Much of the argument will refer to an underlying controversy between psychology as a science and the practice of psychology, a controversy that is stronger than in most other sciences, but nevertheless needs to be resolved.
