The method of hierarchical information integration can be applied to the study of complex decision-making processes in which preference formation is influenced by many attributes of choice alternatives. In this paper, we extend Louviere's (1984) original approach to include the modeling choice processes in addition to judgment processes. Assumptions underlying the original and our extension are discussed and the new method is applied in an analysis of residential choice behavior.  相似文献

Restoration requires the use of appropriate characterization methods and suitable new material preparation processes permit the reproduction of the original material to be as similar as possible in order to be an appropriate application method. The combination of these factors will facilitate a good restoration process. Different stuccos were taken from El Museo del Calendario, a building located in Querétaro, Mexico which was built in the 16th century. All the stucco samples were studied using the characterization process which is proposed in this article. The characterization method consisted of the use of analytical techniques, such as X‐ray diffraction, Fourier transform infrared and scanning electron microscopy. This characterization method made reproduction of the original material possible. The new material combined with new application techniques developed in situ will result in a high‐quality restoration process.  相似文献

Abstract

An invited address in 1964 constitutes the pre-history of fractals, and a justification is given here why its publication is now of interest because of its interdisciplinary nature. Fractal geometry has been successful as mathematics and has – through computer graphics – pioneered a new art. But until 1975, the author's work was generally considered as premature. In the original address of 1964, which here follows the historical introduction, the author states the mathematical basis for his philosophy of the Second Stage of Indeterminism in Science. The term fractals was not coined until 11 years after the original address of 1964.  相似文献

This paper puts into question the conventional way of delineating tourism destination borders in terms of taken-for-granted administrative boundaries. Despite the fact that the literature on destination boundaries advocates for conceptual frameworks where customers’ consumption patterns play a more fundamental role, instances of actual attempts of structuring tourism geographies into ‘new tourism areas’ are scant, and instances of zoning on the basis of visitors’ consumption patterns are absent. A method for identifying alternative and more effective consumption-based tourism zones that combines geographical information system and hierarchical cluster analysis techniques, and that relies on time distances between attractions, is thus proposed, and implemented in the case of the Pyrenees mountain region. As a result the region is restructured into nine new tourism zones, which, compared to the original destinations, are more uniform in size and have a higher correlation index between attractiveness and accommodation intensity; they also have different levels of cross-border intensity and are very similar to historical regions; and the more they differ from the original destinations the higher their attractiveness, which supports the effectiveness of the new zoning technique. Four types of tourism zones ranging from higher to lower tourism intensity are also identified.  相似文献

A number of different and partly contradictory interpretations about the suspension and the indicator system of the ancient Egyptian balance has been given so far. In this article previous explanations of these devices are presented and critically considered; at the same time the balance of the Egyptians is included in the complete evolution of this instrument. Based on original Egyptian colour drawings on papyrus taken from the Book of the Death and considering weighing techniques, it is stated that all interpretations given so far are not capable of providing a satisfactory explanation of the function of these devices. The interpretation given already in 1888 by Sir Flinders Petrie comes closest to the real function of the indicator system: According to his assumption the device consisted of a solid pointer attached to the beam, in relation to which a plumbline was observed after the oscillations had stopped. This interpretation, however, has to be varied or to be complemented by taking into consideration the special drawing technique of the ancient Egyptians: Processes were drawn in a reproduction technique which consisted in the simultaneous combination of a top view and a side view. A new hypotheses about the function of the suspension and the indicator system of the ancient Egyptian balance is presented, which has the advantage of agreeing completely with the Egyptian drawing technique and which, in addition, ensures optimum precision of the weighing procedure.  相似文献

The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.  相似文献

The applicability of a new, fully probabilistic approach to seismic design and assessment of reinforced concrete (RC) structures is investigated. Fundamental advantages of the method are mathematical simplicity and comparatively light computational effort. The original formulation, which was developed for steel structures, is first illustrated; ah extension which allows consideration of multiple failure mechanisms, typical of RC structures, is then proposed. The applicability of the method is demonstrated through an example: the seismic risk of a four storey RC building that was not designed for seismic resistance is evaluated. Three failure mechanisms are considered: joint failure, column shear failure and drift failure.  相似文献

The current debate about the age of the Romanesque frieze of Lincoln Cathedral weighs archaeological evidence against art history. On the one hand, the panels appear to be an integral part of the original Norman structure built by the first bishop (AD 1072–92). However, on grounds of style and artistic comparisons, art historians argue for a later installation during the restoration of AD 1141–6. In order to determine when the panels were stabilized in the cathedral, we used a new method that measures their degree of remagnetization by the earth's magnetic field since they were quarried. The longer that masonry remains stabilized in a given orientation, the greater its viscous remagnetization. Viscous remanent magnetization dating has previously been successful with this particular type of limestone masonry. Our results lend support to the view that the panels were installed in the early 1140s.  相似文献

The Booker method of ray tracing is useful for tracing the paths of radio rays in a plane stratified magneto-plasma, and a brief summary is given. In its simplest form it is used for tracing a single ray, without taking account of the configuration of neighbouring rays. Two extensions of the method are discussed. The first is the effect on the signal amplitude of the divergence or convergence of neighbouring rays in a thin ray pencil. The second is the technique of complex rays and complex space, which are especially useful when electron collisions introduce attenuation of the waves. Some typical results for both extensions are presented. This paper is mainly a tutorial paper, but some new results are given, including a method for dealing with a singularity in the equations for the ray divergence effect.  相似文献

This paper considers the impact of technology on methods used to classify land potential. With developments in new technologies such as Expert Systems (ES) and Geographic Information Systems (GIS), McKeown (1987) proposes a new method by which to explain the decision making process for land classification to an end user. Consideration is given to McKeowns' concept and the literature reviewing both traditional land classification methods and ES and GIS systems.  相似文献

The measurement of the fineness of debased ancient silver coins has proven to be a very difficult issue, which has been studied for a long time. In this paper, this subject is analysed, and the various consequences of the silver surface enrichment (SSE) are discussed exploiting the most recent investigations. A new model is proposed for the complex object that is an ancient-debased silver coin, based on the silver profiles measured on some sectioned specimens. The model is applied to a sample of 43 coins, mainly Roman victoriati, Cisalpine and Illyrian drachms (from late III to I century B.C.). The coins are investigated in two different ways: neutron diffraction (ND) and specific gravity (SG). The results of the two measurements are combined via the proposed model to provide a more complete numismatic information of the original fineness of the monetary alloy. As a result, a relation between SSE thickness and SG is derived, which, for these coinages, allows to estimate the original alloy silver content from a simple SG measurement; the same method can be used to study other debased coinages, provided that all the procedure (ND and SG) is applied.  相似文献

The solubility profile technique is a means of characterizing the mineral phase of bones and fossils from archaeological and palaeontological sites. The method is based on the differential dissolution of variously substituted apatites in acetate buffer at pH 4.5. The original solubility profile protocol, which involves repetitive washing and centrifuging, is extremely cumbersome and time-consuming. Here we describe an alternative, automatic method in which the fossil bone preparations are dissolved in a perspex cell. The behaviour of fossil preparations in the manual and automatic protocols are compared. We conclude that the dissolution cell is satisfactory for routine applications, but that the original, manual protocol is preferable for preliminary investigation of untested assemblages.  相似文献

This paper analyses book dedications in a specific genre, religious writing, in a linguistically small and peripheral region of the Habsburg Empire, endeavouring thereby to open up new comparative perspectives in the understanding of the system of patronage. After a review of the most frequent problems encompassed by recent research, the specific features of the concrete original research corpus are elaborated, with an emphasis on problems hitherto less investigated: the correlation of the dedication and other paratextual parts of the book; the practice of dedicating works to saints of the Catholic Church, which relativises the understanding of the dedication as a form of the exchange of authorial work for material benefits; and the functionalisation of the name of the patron, which enables the creation of the concept of the patron function. The analysis supports the understanding of patronage as a dynamic system that rested upon the human interactions possible in the given and specific spatial and temporal contexts.  相似文献
