Topological relationships present some important information for describing the relative position of objects. From a mathematical point of view, topological relationships are invariant at different scales. However, in practice, they may be changed for diverse reasons, such as the limitation of digital devices. These different topological relationships concerning the same objets can cause inconsistencies when answering to queries in amultidatabase environment. In this paper, a constraint model for analyzing the possible changes of topological relationships in spatial datasets at different scales is presented. With development of the Internet, people have more opportunities to use various spatial datasets at different scales. This work can be applied to analyze the inconsistencies ofinteroperations among different spatial datasets in this environment. In spite of the studies focusing on spatial datasets, the result also agrees with Euzenat's work about granularity analysis on temporal relationship (Euzenat 1993, and 1995).
Marijuana is the most widely used illicit drug in the United States and both proponents and opponents of its use and legalization have had a lot to say about how it's good or bad for you. Some of the claims made for or against marijuana are scientifically well-grounded and some are not. How can you tell which is which? The National Academies of Sciences, Engineering, and Medicine (NASEM) have recently released a thorough, rigorous and weighty report that answers this question. From this point on, anyone who tells you how marijuana can help you, hurt you or not affect you that cannot support their claims with the research summarized in the NASEM report is blowing smoke.
