The increasing complexity and flexibility of modern land use requires that cadastres need an improved capacity to manage the third dimension. As the world is per definition not static, there also will be needs in relation to the representation of the temporal (fourth) dimension either integrated with the spatial dimensions or as separate attribute(s). In this paper, registration of utility networks in cadastre are considered in this 3D + time (=4D) context. A number of countries in the world have developed methods to register utility networks complying with their legal, organizational, and technical structure. We researched the different approaches of three specific countries: Turkey, The Netherlands and Queensland, Australia. These are analysed to evaluate a solution that matches legal, organizational, and technical cadastral requirements in the most optimal way. 相似文献

This article examines, the character and significance of 'strategies' formulated within the R&D function of a business, and their relatzonship to the broader business strategy of the parent company. The discussion forms a basis for the analysis of case studies of three large UK companies, which will be published later as Part 2 of this article Part 1 of the article identifies three foci of innovation studzes: first, that of the innovations themselves; secondly, that of patterns of innovation within discrete industrial sectors; thirdly, that of the innovating firms and their strategies. The discussion focuses on the third topic nad explores two aspects of the tehnological components of innovation strategies. First, the shape of the prorgolio of products under development, the technical and market specificities they possess, and secondly, the structure of the portfolios of technologies required and used in those products. These dimensions of strategy combine both firm-specific and public-domain tecnoligical competenes. These competences affect both the competitive position and the strategic direction of firms. Finally, the article proposes some analytical devices for making sense of technology strategies in the thre firms studied. Part 2 of the article presetns the substance of the case studies, and reviews the lessons which they reveal. 相似文献

The objective was to describe the relationship between epidemiological and biomechanical factors in the causal pathway of inflatable rescue boat (IRB)-related injuries in Australian surf lifesavers; to develop epidemiological and biomechanical methodologies and measurement instruments that identify and measure the risk factors, for use in future epidemiological studies. Epidemiological and biomechanical models of injury causation were combined. Host, agent and environmental factors that influenced total available force for transfer to host were specified. Measurement instruments for each of the specified risk factors were developed. Instruments were piloted in a volunteer sample of surf lifesavers. Participant characteristics were recorded using demographic questionnaires; IRB operating techniques were recorded using a custom-made on-board camera (Grand RF-Guard) and images of operating techniques were coded by two independent observers. Ground reaction forces transmitted to the host through the lifesaver's feet at the time of wave impact were measured using a custom-built piezoelectric force platform. The demographic questionnaire was found practical; the on-board camera functioned successfully within the target environment. Agreement between independent coders of IRB operating technique images was significant (p < 0.001) with Kappa values ranging from 0.5 to 0.7. Biomechanical instruments performed successfully in the target environment. Peak biomechanical forces were 415.6N (left foot) and 252.9N (right foot). This study defines the relationship between epidemiological and biomechanical factors in modifying the risk of IRB-related injury in a population of surf lifesavers. Preliminary feasibility of combining epidemiological and biomechanical information has been demonstrated. Further testing of the proposed model and measurement instruments is required. 相似文献

The authors argue that most current prognostications of the employment implications of new microelectronic technologies exaggerate the rate at which they will be introduced and, by taking the national or international perspective, pay too little attention to smaller regions. A survey of Tameside, a part of Manchester, UK, shows that, although many jobs are at risk in some industries, the overall changes during the 1980s are unlikely to be as great as might have been supposed; this is because of the industrial structure of that particular locality. 相似文献

In nonconvex environments, a sunspot equilibrium can sometimes be destroyed by the introduction of new extrinsic information. We provide a simple test for determining whether or not a particular equilibrium survives, or is robust to, all possible refinements of the state space. We use this test to provide a characterization of the set of robust sunspot-equilibrium allocations of a given economy; it is equivalent to the set of equilibrium allocations of the associated lottery economy.

This paper reports on the results of an analysis at Centre for Research on Innovation and Competition (CRIC) of the data from the 1996 and 1997 Survey of Innovation Trends conducted by the Confederation of British Industry (CBI) in conjunction with the NatWest Bank in the UK. This is one of the few, direct surveys of innovation activity, as opposed to R&D and patenting actvity, which is conducted in the UK It is characterized by the fact that it asks responding firms to report on trends in a wide variety of aspects of their innovative behaviour. The central feature of the analysis in this paper is a factor analysis of the answers to a set of 15 questions on different aspects of innovative behaviour. This results in a three-factor solution which reveals three distinct ‘styles’ of innovation in the behaviour of respondents. These three styles are shown to be broadly applicable to both manufacturing industry firms and service industry firms in the sample, thus revealing a dimension of innovation in the service sector which is not so readily disclosed by analysis of R&D or patent statistics. Statistical modelling of the constraints and incentives influencing innovation shows that while constraints do not appear to be very significant, competitive pressure and the utilization of collaborative linkages are strongly positively associated with innovation, and especially with a more radical s o b of innovation. Ihe paper concludes that the CBI survey provides data about innovation in the UK which are not easily provided through other means. Its format allows certain aspects of innovation—particularly the similarities and differences between manufacturing and services —to be examined in an interesting way. 相似文献
