Cadastral information is a reference data component, of any spatial data infrastructure (SDI). During recent years, several organisational and individual research projects have investigated the cadastral domain. Two paradigms characterize much of this research and their methodologies: a behavioural paradigm or, alternatively, a ‘design research’ paradigm. While some efforts have focused on behavioural research methodologies, design research methodologies have not been addressed by the cadastral, geographical information system (GIS) and SDI research community so far. The present article, therefore, aims to demonstrate usage of the design research paradigm through a methodological analysis of recent cadastral research, which addresses information system issues and within this context, designs information system artefact. The analysis is based on five doctoral dissertations and an array of papers representing the development of the ISO/WD 19152.3 Land Administration Domain Model. The analysis is supplemented with a review of related theory. The main contribution of this article is an explication of a design research methodology and a theoretical framework for research in cadastral information, cadastral systems and the units of property rights reflected in these systems.  相似文献

I argue that intentional psychology does not stand in need of vindication by a lower-level implementation theory from cognitive science, in particular the representational theory of mind (RTM), as most famously Jerry Fodor has argued. The stance of the paper is novel in that I claim this holds even if one, in line with Fodor, views intentional psychology as an empirical theory, and its theoretical posits as as real as those of other sciences. I consider four metaphysical arguments for the idea that intentional psychological states, such as beliefs, must be seen as requiring in-the-head mental representations for us to be able to understand their characteristic causal powers and argue that none of them validly generate their desired conclusions. I go on to argue that RTM, or some computational version thereof, is not motivated by appeal to the nature of cognitive science research either. I conclude that intentional psychology, though an empirical theory, is autonomous from details of lower level mechanism in a way that renders RTM unwarranted.  相似文献

American culture is filled with cultural products. Yet few studies have investigated how changes in cultural products correspond to changes in psychological traits and emotions. The current research fills this gap by testing the hypothesis that one cultural product—word use in popular song lyrics—changes over time in harmony with cultural changes in individualistic traits. Linguistic analyses of the most popular songs from 1980–2007 demonstrated changes in word use that mirror psychological change. Over time, use of words related to self-focus and antisocial behavior increased, whereas words related to other-focus, social interactions, and positive emotion decreased. These findings offer novel evidence regarding the need to investigate how changes in the tangible artifacts of the sociocultural environment can provide a window into understanding cultural changes in psychological processes.

The net imports of oil increased by 8.4% in China in 2007, hitting the record of 183.48 million tons (Fig.1). The net imports of crude oil and other oil products including paraffin wax, oil coke, and asphalt increased and balanced out the decrease of the net imports of product oil and liquefied petroleum gas (LPG). The net imports of crude oil reached 159.35 million tons, up 14.8%. In 2006, a lot of refining refineries were newly built and expanded, as a result, the crude processing capacity of domestic refineries increased by 6.4% and rose to 326.79 million tons in 2007.  相似文献

We study the isomorphic implication problem for Boolean constraints. We show that this is a natural analog of the subgraph isomorphism problem. We prove that, depending on the set of constraints, this problem is in P, or is NP-complete, or is NP-hard, coNP-hard, and in PNP. We show how to extend the NP-hardness and coNP-hardness to PNP-hardness for some cases, and conjecture that this can be done in all cases.
