Applying Measures of Spatial Autocorrelation: Computation and Simulation

Knowing about the challenges and opportunities of spatial autocorrelation is one thing, but applying the measures to one's own data is another matter entirely. While manual computation of the measures for toy data sets is possible, applying them to small data sets required the use of computers and thus software. This article will shed some light on how the measures were and are implemented in software and on implementation issues that are still not fully resolved.     

The Study of Local Public Economies: Multi‐organizational,Multi‐level Institutional Analysis and Development

One important extension of the IAD framework has been to the study of local public economies. These are multi‐organizational, multi‐level arrangements defined as the set of governmental jurisdictions, public and nonprofit agencies, and private firms that interact in various patterns to provide and produce public goods and services within a specific locality or region. Commonly, the localities or regions studied from this perspective have been U.S. metropolitan areas, often defined as a central city and its surrounding or adjoining county. Localities can be delineated, however, on various terms, and in the IAD framework, it is the geo‐physical nature of a locality that, in substantial part, drives the analysis. One of the strengths of the approach is its capacity to explain local variations in public organization as a function of the geo‐physical diversity of localities, while at the same time developing empirical generalizations and normative principles that apply across diverse regions. What, for example, might the organization and governance of a complex metropolitan area have in common with the organization and governance of a complex protected area, such as the greater Yellowstone eco‐region or the Adirondack Park? Construing both sorts of regions as local public economies can enhance our overall understanding of public organization at the same time that it permits a more nuanced understanding of diverse localities. Such work contributes to the ongoing IAD project of “understanding institutional diversity.”     

Elemental Analysis of Ochre Outcrops in Southern British Columbia,Canada

Ochre is a red mineral pigment that was a key element of social and ceremonial practices among cultures of the Pacific Northwest Coast. It is recovered routinely from archaeological excavations, is visible as pigment for pictographs, and is described in the historical record as a trade item and component of ceremonial practices. Despite its ubiquity in the archaeological record, it is difficult to interpret its significance without first understanding the nature of its procurement and distribution. As a step towards identifying procurement practices, trade and resource use, it is necessary to thoroughly characterize ochre outcrops with regard to their intra‐source and regional variability. We analysed ochre from three outcrops using INAA to determine their elemental chemistry. The purpose of this study is threefold: to provide an example of the range of elemental variability within and between outcrops, to illustrate the effect of scale and geomorphological processes on elemental compositions and statistical interpretation, and to create a database of known deposits in southern British Columbia. The results demonstrate that ochre deposits may be differentiated on the basis of their chemistry, and that conservative statistical interpretation needs to be employed to assess true elemental variability within and between ochre deposits and regions.     

Interpreting the Moon Landings: Project Apollo and the Historians

By focusing on the key book‐length studies of the Apollo program that landed American astronauts on the Moon in the 1960s and 1970s, this essay seeks to evaluate the historiography about Apollo in the first decade of the twenty‐first century, dividing the subject into five major areas. The first area is the foreign policy and public policy antecedents of Apollo and its immediate ramifications; some of these efforts have yielded significant studies. The second area involves the evolution of space hardware, in many instances these are overwhelmingly detailed studies of rockets and other space flight technologies. Third, there is a great fascination with the astronauts and their actual flights, and a rich tradition of memoir and narrative exists in this arena. The fourth area receiving attention from historians of Apollo and the lunar voyages emphasizes the history of science, in which much of the focus is on the scientists, scientific findings from the voyages of discovery, and the use of this evidence in developing larger theories about the origin and evolution of the solar system. Finally, and increasingly so in the last 20 years, the Apollo story has been recontextualized through social and cultural investigations of its meaning in modern America. Assessing the five major areas enumerated above, this essay also offers some possibly fruitful avenues of future research.     

Perception of Sacred Space

Discrimination of space into sacred and profane is as old as mankind. This study suggests a typology for categorizing sacred Space at three broad levels: mysticoreligious, homelands and historical. Each is further divided on the basis of the extent of the group which shares the consensus view of sanctity. Recognizable levels include international, national, regional, community, neighborhood and individual sacred space. The Mormon culture was used as a basis to test the validity of the proposed typology through use of two questionnaires administered to Mormons. The first questionnaire was an open-ended survey to determine all important regions which were recognized as sacred. The second questionnaire was then prepared which required respondents to rank 15 sacred sites or regions in terms of their sanctity. An analysis of the responses indicates that those sites which are perceived as most sacred are mystico-religious sites where Mormons believe contact occurs between divine powers and man. The next level of sanctity was applied to homelands. The recognized homelands include Utah and Jackson County, Missouri which the Mormons view as a promised land. The third and lowest level of sacred space includes sites of historical importance to Mormons.
