This article studies employment location patterns in the Puget Sound Region of Washington State at a micro level of geography. Traditional discrete choice modeling using multinomial logit (MNL) models may be problematic at a micro level of geography due to the high dimensionality of the set of alternative locations and the likely violations of the independence from irrelevant alternatives (IIA) assumption. Count models are free from the IIA assumption and, unlike logit models, actually benefit from large numbers of alternatives by adding degrees of freedom. This study identifies the best-fitting count model as the zero-inflated negative binomial (ZINB) model, because this model more effectively addresses the large number of cells with no jobs and reflects a dual process that facilitates the identification of threshold clustering effects such as those found in specialized employment centers. The estimation and prediction results of ZINB are compared with those of MNL with a random sampling of alternatives estimated on an equivalent data set. The ZINB and MNL models largely agree on major trends, with the ZINB model providing more insightful details, but with less capacity to predict large count situations.  相似文献

The author, based on field work, interviews, and examination of local and regional literature and official statistical sources, compares the experience in agrarian reform in two disparate locations—KostToma Oblast, northeast of Moscow in the Noncher-nozem Region, and Rostov Oblast on Russia's Black Sea littoral in the fertile Chernozem (Black Earth) region. It examines both the reorganization of state and collective farms and the establishment of private peasant farms in the two oblasts, with particular emphasis on the latter. The sections on private farms represent an initial attempt, based on in-depth information for a limited sample population, to garner insights, at the rayon level, into factors that may be influencing regional variations in the number, size, and location of private farms across the Russian countryside. 2 maps, 6 tables, 53 references.  相似文献

This paper compares the performances of three exploratory methods for cluster detection in spatial point patterns where the at-risk population is known. After reviewing two existing methods, Openshaw et al. (1987) and Besag and Newell (1991), an alternative method is introduced. These three methods are then compared empirically using two point patterns drawn from a disaggregate housing database consisting of 28,832 observations. Each observation in the data set contains attributes of single-family detached dwellings in the City of Amherst, New York. This paper provides some new insights into the performance of the three methods, as previous applications have used spatially aggregated (and hence rather inaccurate) data. The paper also demonstrates the utility of GIS for this type of spatial analysis.  相似文献

The technology of the end products i.e. blades and points in Late Pleistocene stone artefact assemblages from Klasies River, South Africa, and the Nile Valley, Egypt, are compared. The comparison includes univariate and multivariate analysis of metrical attributes enhanced by graphical biplot displays. The end products in these assemblages are either dominantly points or blades and this is related to the core reduction strategy adopted. The MSA 11 from Klasies River and the Nubian Complex industry from the Nile Valley are point industries made in the Levallois tradition, while the MSA 1 from Klasies River and the Taramsan from the Nile Valley may be non-Levallois or adapted Levallois blade industries. Dating of the assemblages shows the changes between dominant core reduction strategies are sequential and time restricted in both South and North Africa. It is concluded that variability of the same kind occurs in Middle Stone Age and Middle Palaeolithic assemblages south and north of the Sahara in the early Late Pleistocene.Dans cet article, les technologies des produits recherchés, des lames et des pointes, pour certains ensembles lithiques de Klasies River, Afrique du Sud et la Vallée du Nil, Egypte, sont comparées. Cette comparaison implique des analyses univariées et multivariées de variables métriques biplot. Les produits recherchés sont bien des pointes que des lames, selon les stratégies dexploitation adoptées. Le MSA II de Klasies River et le Complexe nubien de la Vallée du Nil sont des industries à pointes issues de la tradition Levallois. Par contre, le MSA I de Klasies River et le Taramsien de la Vallée du Nil évoquent une technologie de production non-Levallois ou Levallois modifiée. Les éléments de datation disponibles indiquent que les changements dans la prépondérance des stratégies dexploitation senchaînent dans une séquence chronologique bien identifiable, aussibien dans lAfrique du Sud que lAfrique du Nord. On arrive à la conclusion quune variabilité du même caractère est attestée dans les ensembles du Middle Stone Age et du Paléolithique moyen au sud et au nord du Sahara, pendant le Pléistocène supérieur ancien.  相似文献

In the late Ottoman and Mandatory periods, Palestine's rural landscape underwent a great transformation. This study examines how the Muslim population expanded beyond its traditional inhabitation in the highlands and settled the fluid inventory of marginal lands in the coastal plains and unpopulated valleys of Palestine. In settling these marginal landscapes their settlement dovetailed with Jewish settlement patterns. While most studies have emphasized the competitive aspect of this process, examining Zionist and Arab national claims, this research points to a different aspect of this new settlement—mainly how much the Jewish and Muslim settlement patterns mirrored one another and how they were part of similar physical processes and complemented one another. Relying on censuses, aerial photographs, and period maps, as well as other archival sources, this is the first systematic research to examine the full extent of new Muslim settlements in Palestine in the late Ottoman and Mandatory periods, and to draw parallels between this phenomenon and the settlement endeavors of the Zionists.  相似文献

This paper reviews the opportunities and challenges for re-framing the purpose, process, product and assessment of final-year geography dissertations. It argues that the academic centralities of critical thinking, analysis, evaluation, effective communication and independence must be retained, but that the traditional format limits creativity and innovation. Re-imagining capstone projects has implications for students, faculty, departments and institutions, but greater diversity could enhance its relevance to students and employers, better aligning the student experience with the academic interests and future career demands of the 21st century graduate.  相似文献

Unlike other European countries, most industrial policy in Austria still takes place at the Federal level. With recent open access to European funding programmes on the one hand and increasing regional engagement in industrial policy questions on the other, we see ongoing changes in this structure. As a result, industrial policy strategies for Austria are more and more designed in close complementarity with both international and regional strategies. The recent shift toward technology policy observeable in nearly all industrialized countries has also taken place in Austria and has favoured major urban areas. Nevertheless, a consensus-oriented tradition in stabilization and social policy have had remarkable negative effects on laggard regions up to now. The plan of this paper is documenting the actual situation as well as recent chances in Austrian industrial and technology policy. Furthermore, philosophy, principal targets and instruments of new industrial policy at the Lander level (Styria) are examined to offer a closer view on advantages and possible disadvantages of regional industrial policy.  相似文献

Telephone traffic is shown to be a reliable indicator of functional ties, with morning peak calls concentratedalong hierarchical pathways andevening peak calls more sensitive to population and distance. Traffic dispersion incident to each centre is systematically related to the size of the centre and to the size and spacing of interacting centres. Metropolitan orientation has a powerful effect on traffic dispersion in all situations and, in the more centralised states, negates the relationship between centre size and dispersion and converts the customary distance-decay cones into an elevated surface of strong metropolitan orientation, broken by inverted cones around a few regional centres. Middle-order nodal regions are delineated and intra-regional flows analysed using primary linkage and standardised scores. Three distinctive systems of regional-ordering are described, namely metropolitan-dominated, provincial-city dominated and multi-ordered.  相似文献

In the philosophy of science there has traditionally been a tendency to regard physics as the incarnation of science per se . Consequently, the status of other disciplines has been evaluated according to their ability to produce laws resembling those of physics. This view has yielded a considerable bias in the discussion of historical laws. Philosophers as well as historians have tended to discuss such laws mostly with reference to the situation in physics; this often led to either one of two conclusions, namely that (1) history is epistemologically completely separated from natural science because it does not have universal laws, or that (2) the ultimate goal of the study of history must be the formulation of such universal laws. I maintain that neither conclusion is necessary. To substantiate this position, I discuss several aspects of natural laws. One aspect that is often neglected is that there are many kinds of statistical laws in nature; there is no close link between laws and determinism. Moreover, natural systems exist that have a history, that is, systems that are, like human history, shaped by irreversible, singular events. One important case is biological evolution; accordingly I discuss the relation between evolutionary theory and historiography. However, since we are part of the living world, and in addition to considering the methodological similarities between the two fields, one could also ask whether the laws of evolution are of direct relevance for understanding our history. This issue of history as evolution is investigated in detail in the final section of the paper.  相似文献

Scholars are increasingly interested in innovation in peripheral areas. However, research and policy documents are still often based on a traditional understanding of the core–periphery dichotomy. Here, the peripheralization discourse argues for a broader understanding and highlights the importance of economic, demographic, and political factors as well as knowledge intensity for defining core and peripheral areas. Concerning the latter, the differentiated knowledge base approach provides new insights, as it emphasizes the varying foundations for different kinds of innovations. By combining these hitherto unconnected strands of literature, this paper first develops a conceptual framework for a new regional typology, which considers both the degree of centralization/peripheralization and the prevailing knowledge base. Second, an exploratory analysis applies this framework to the 95 districts of Austria and provides first insights into peripheralization and issues of regional prosperity. The results show that there are indeed many nuances and that regions that are clearly either central or peripheral are the exception. Furthermore, peripheries come in many shades and are not uniform, as often assumed implicitly. Consequently, this paper argues that a tailor-made innovation policy for lagging regions would benefit from the incorporation of the peripheralization discourse. To conclude, it outlines directions for future research.  相似文献

Summary

Early modern Europe experienced an expansion of both governmental institutions and the responsibilities they assumed. These changes were accompanied by protracted conflict. This article traces the philosophy of state developed by Austria's estatist opposition during the early decades of the seventeenth century. In the writings of Georg Erasmus von Tschernembl, especially, an alternative vision of state and governance took shape, whose implementation would have transformed the history of Central Europe. It took a continental war to resolve this fundamental ideological discord in favour of the Habsburg dynasty.  相似文献
