Estuarine Acidification: Impacts on Aquatic Biota of Draining Acid Sulphate Soils

Acid sulphate soils form when iron pyrite oxidises to sulphuric acid on atmospheric exposure, lowering soil pH below 4. In the Richmond River estuary, northern New South Wales, flood mitigation, drainage works and floodplain excavations have augmented acid sulphate soil formation by increasing pyrite availability for oxidation. These engineering works have facilitated the transport of acidified water and have impeded recovery from tributary acidification. The increased frequency and duration of acidification are associated with elevated concentrations of inorganic monomeric aluminium and dissolved iron, and major iron hydroxide precipitation, with deleterious effects on exposed aquatic biota and habitat. Fish kills and an outbreak of epizootic ulcerative syndrome (EUS) have been recorded from acidified sites in the estuary.

Structure and Agency in the Holocaust: Daniel J. Goldhagen and His Critics

A striking aspect of the so-called "Goldhagen debate" hasbeen the bifurcated reception Hitler's Willing Executioners hasreceived: the enthusiastic welcome of journalists and the public was as warm as the impatientdismissal of most historians was cool. This article seeks to transcend the current impasse byanalyzing the underlying issues of Holocaust research at stake here. It argues that a "deepstructure" necessarily characterizes the historiography of the Holocaust, comprising atension between its positioning in "univeralism" and"particularism" narratives. While the former conceptualizes the Holocaust as anabstract human tragedy and explains its occurrence in terms of processes common to modernsocieties, the latter casts its analysis in ethnic and national categories: the Holocaust as anexclusively German and Jewish affair. These narratives possess important implications for thebalance of structure and human agency in the explanation of the Holocaust: where theuniversalism narrative emphasizes the role of impersonal structures in mediating human action,the particularism narrative highlights the agency of human actors. Although historical accountsusually combine these narratives, recent research on the Holocaust tends in the universalistdirection, and this bears on the sensitive issue of responsibility for the Holocaust byproblematizing the common-sense notion of the perpetrators' intention and responsibility.Goldhagen is responding to this trend, but by retreating to the particularism narrative andemploying an inadequate definition of intention, he fails to move the debate forward. It is time torethink the concept of intention in relation to events like the Holocaust.     

Discovering the invisible Puerto Rican slave family: demographic evidence from the eighteenth century

Traditional notions that family life among slaves during the pre-plantation period in the non-Hispanic Caribbean was necessarily unstable are fading in light of new research. Although marriage among this segment of the population in Caguas, Cayey, San Germán, and Yauco--rural parishes in Puerto Rico--involved only a fraction of the overall number of marriages in these communities, the marriage of slaves was much more frequent than previously assumed. Family life among the eighteenth-century Puerto Rican slave population appears to have been quite stable, as shown by the reconstruction of birth intervals for both married and unmarried mothers. Married and unmarried mothers exhibited similar reproductive behavior. These results strongly suggest that a majority of the unmarried slave mothers lived in unions that were not institutionally recognized, but that were nevertheless stable, as indicated by the high percentage of their children born at intervals comparable to those of married mothers. If unmarried mothers were living in stable consensual unions, then our understanding of these slave family units during the colonial period must be reassessed not only for Puerto Rico but possibly for the rest of the Caribbean and Latin America.     

Cities and Privatization

Cities across America look for management strategies useful for accomplishing their responsibilities and programs. While some cities include privatization strategies in their management portfolios, others do not, and the underlying reasons are not readily apparent. This study seeks to gain some insight into this disparity through several questions: Why do some cities use more privatization than others? Are privatization levels higher in fiscally healthy or fiscally stressed cities? Where are the cities that use privatization located? This study attributes municipal privatization levels in medium-sized cities, in part, to degree of wealth, fiscal stress, and location. The findings suggest that privatization levels are higher in wealthy, fiscally healthy, suburban cities.
