Trajectories of Culture in West Mexico

Explaining culture change requires a multi-dimensional approach, and so does explaining cultural continuity. I combine several approaches to explain why the account given of a Mexican town's history changed between 1879 and 1992. I also identify and explain what did not change during the period, as well as during the subsequent period of fieldwork itself, 1992–2005. Rather than treat cultural continuity as the result of inertia, I follow Urban ([2001], Metaculture: How Culture Moves Through the World, University of Minnesota Press, Minneapolis, MN) in looking for what motivates the transmission of culture as well as what pathways it takes, although I prefer to stress human agency in writing of the trajectories along which people propel culture, in this case a town's history. One approach which I draw, for explaining the trajectories of culture, is Malinowski's seminal study of Trobriand myths (1926), but I combine it with the more recent approaches that link versions of history to the interests of social groups; highlight the density of ties between person, people and place; pay attention to the genre of narratives being transmitted, and to the skewing of culture towards central places; and finally, consider shifts not just in the figure of particular narratives but in the grounds that underlie them, such as the criterion of truth against which narratives are measured.     

Traditional and computed tomographic (CT) techniques link modern and Cenozoic fruits of Pleiogynium (Anacardiaceae) from Australia

Computed tomography (CT) and traditional techniques were used to study the internal morphology of modern fruits of Pleiogynium timoriense (DC.) Leenh., and phosphatized and silicified fruits that were considered to belong to the genus. The results demonstrate that phosphatized fruits from the Oligocene–Miocene Dunsinane site at Riversleigh and silicified fruits from the Oligocene Glencoe Site, which are both in Queensland, are referable to Pleiogynium. The Riversleigh material (Pleiogynium wannanii Rozefelds, Dettmann & Clifford sp. nov.) is very similar to extant P. timoriense (DC.) Leenh. Both possess locules that, in the vertical axial plane, are asymmetrically reniform and enclosed by a two-layered endocarp, the inner layer woody and resistant to decay, the outer of fibres and parenchyma, surrounded by a mesocarp of fibres and sclereids and a parenchymatous exocarp. The outer mesocarp is sculpted by meridionally arranged, elongate depressions (germination apertures) situated at the dorsal surface of each locule; erosion of the mesocarp and outer endocarp provides passage for emergence of the embryo’s radicle on germination. The silicified material from Glencoe (P. parvum Rozefelds, Dettmann & Clifford sp. nov.) is smaller in all its parts and has locules that are ovate in the vertical axial plane. Discrete, cap-like, opercula are not evident in the fruit wall of the fossil and extant fruits studied. The presence of Pleiogynium, and associated taxa, indicates the existence of rainforest communities at Glencoe, and mixed open forest/rainforest at Riversleigh during Oligocene–Miocene times. The multilocular, fossil fruit described as Pleiogynium mitchellii Collinson, Manchester and Wilde from the Eocene deposits at Messel Quarry, Germany, is not considered to belong in the genus, as evidence of elongate depressions on the dorsal surface of the fruit stones has not been demonstrated conclusively, and its internal morphology/anatomy differs significantly from that of Pleiogynium.

Interstate Migration: A Test of Competing Interpretations

This study presents a model of net interstate migration in the United States during the 1970s. Of 5 composite dimensions derived from an exploratory factor analysis of 20 candidate predictors of interstate migration, the greatest predictive power in an ordinary least squares regression analysis is attained by a set of quality-of-life correlates of migration. Composites of fiscal policy and labor relations variables, more controllable by public decisionmakers, are also significant.     

Methodologies for Examining Homelessness and Their Application to a Mandated Statewide Study

Using findings from a federally mandated statewide study of homelessness in the state of Iowa, this paper presents methodologies developed to address various aspects of homeless research, including enumeration of the population, screening for reporting duplications, estimating the annual number of incidents of homelessness, and exploring county-level estimates of homelessness. After implementing an algorithm to eliminate duplicate reporting, and using the baseline unduplicated reported number of homeless persons, a statewide estimate of the number of homeless individuals was derived. Following further adjustments for differences in agency reporting practices and after extrapolating for nonreported time periods, we estimated the number of Unique incidents of homelessness experienced in the state during the year of the study (1997). The policy implications of these findings are discussed.
