ABSTRACT Empirical analysis has lagged behind the impressive additions to the theoretical literature on trade center systems during the past 15 years. This study of the trade center system in Saskatchewan is an attempt to begin to redress the imbalance and to test some of the recently formulated theoretical propositions. Communities are identified according to functional classifications for 1961 and 1981 with the aid of a cluster analysis program, and the validity of the groupings are verified using multiple discriminant analysis. Changes in the size, spacing, and function of clusters and individual communities during the 20-year interval are described and an effort is made to prdvide explanations for the changes observed. 相似文献

New Zealand's fourth Labour government, elected to power in 1984, has become known most generally for two of its policies: a refusal to accept nuclear warships in New Zealand waters, and the vigour and consistency with which it has pursued market orientated economic policies. A post‐election near‐national survey of 1013 respondents is employed to measure the extent to which the two policies may have aided Labour's re‐election in 1987. Contrary to most interpretation hitherto, we find that defence and economic policy opinion were at least of equal importance. But there is further evidence to indicate that defence policy opinion was the more important It is concluded that the expression of “post‐materialist” values through anti‐nuclear politics may have perversely allowed a new materialism to conquer New Zealand politics. 相似文献

New Zealand has had a reputation for high voting participation, but age‐eligible turnout has declined since 1938 and, despite a brief recovery between 1975 and 1984, continued to fall subsequently. By 1990 it was far closer to the average turnout of Western democracies. Brief analysis of aggregate data since 1938 sets the scene for more specific study of individual‐level data from the 1963, 1981, and 1990 elections, which indicates effects which are minimal for institutional factors, small for social and demographic variables, and substantial for changes in public attitudes. In particular, dealignment of the party system and voter demobilisation are associated with declining interest in politics, political efficacy, and party identification. While also associated with extra‐parliamentary mass action to the partial detriment of voting among the university‐educated in 1981, a more general mobilisation of postmaterialist issues was probably responsible for the post‐1975 turnout recovery. After 1984 the longer‐term trend was reestablished. 相似文献

We present a model that accounts for errors in short-cutting to complete a triangular pathway by individuals deprived of visual input. The model assumes that systematic error arises from components of navigation concerned with encoding an internal representation of the pathway, rather than the computation of a homeward trajectory or motor output per se. Subjects' tendency to compress the range of actually produced turns and distances, in comparison to the range of correct values, is attributed to regression toward the mean of encoded values during encoding of segments and turns, in the face of uncertainty about the actual values. Individual-subject variations are attributed to differences in the encoding-function parameters, not to variations in the processes themselves. The model provides excellent accounts of data obtained with triangular pathways but fares less well when pathway complexity increases, at which point errors do not appear to be solely attributable to encoding processes. The sources of error identified by the model are likely to play a role in navigation more generally. 相似文献

In the last decade, conversations around queering of GIScience emerged. Drawing on literature from feminist and queer critical GIS, with special attention to the under‐examined political economy of GIS, I suggest that the critical project of queering all of GIS, both GIScience and GISystems, requires not just recognition of the labour and lives of queers and research in geographies of sexualities. Based upon a queer feminist political economic critique and evidenced in my teaching critical GIS at two elite liberal arts colleges, I argue that the “status quo” between ESRI and geography as a field must be interrupted. Extending a critical GIS focus beyond data structures and data ethics, I argue that geographic researchers and instructors have a responsibility in queering our choice and production of software, algorithms, and code alike. I call this production and choice of democratic, accessible, and useful software by, for, and about the needs of its users, good enough software. 相似文献
