Local Government Implementation of the Americans With Disabilities Act: Factors Affecting Statutory Compliance

One of the questions raised after the signing of the 1990 Americans With Disabilities Act is how local governments would implement the statute. This qualitative study examines 20 cities in two states, categorizing implementation efforts and identifying factors that affect local government compliance with the law.     

Dietary change in Fijian prehistory: isotopic analyses of human and animal skeletal material

We examine evidence for prehistoric diet in the Fiji Islands through the analysis of stable isotope ratios (δ¹³C and δ¹⁵N) for 26 samples of human and animal bones from various archaeological sites, time periods, and local environments. The oldest individuals in this study, dating to about 2700 BP and living on the small island of Waya, consumed a predominantly marine-based diet. Subsequent populations on this island showed reduced consumption of marine resources, with greater reliance on terrestrial ones, throughout the cultural sequence. In contrast, populations of humans and pigs living inland on Viti Levu, the largest island, relied on terrestrial resources since at least 1500 BP. Thus, our results suggest that human and pig diets throughout Fijian prehistory relied variably on marine or terrestrial resources, and this distinction is largely a product of geography. This finding and our analyses provide a model for understanding ancient diets in Remote Oceania.     

Overdone overkill – the archaeological perspective on Tasmanian megafaunal extinctions

The reasons for megafaunal extinction in Australia have been hotly debated for over 30 years without any clear resolution. The proposed causes include human overkill, climate, anthropogenic induced habitat change or a combination of these. Most protagonists of the human overkill model suggest the impact was so swift, occurring within a few thousand years of human occupation of the continent, that archaeological evidence should be rare or non-existent. In Tasmania the presence of extinct megafauna has been known since the early twentieth century (74, 85 and 86) with earlier claims of human overlap being rejected because of poor chronology and equivocal stratigraphic associations. More recent archaeological research has not identified any megafauna from the earliest, exceptionally well-preserved late Pleistocene cultural sites. In 2008 however an argument for human induced megafaunal extinctions was proposed using the direct dates from a small sample of surface bone from two Tasmanian non-human caves and a museum sediment sample from an unknown location in a cave, since destroyed by quarrying (Turney et al., 2008). Turney et al. (2008) supplemented their data with published dates from other Tasmanian caves and open sites to argue for the survival of at least seven megafauna species from the last interglacial to the subsequent glacial stage.     

Geochemical sourcing of basalt artifacts from Kaua‘i,Hawaiian Islands

We report on energy-dispersive X-ray fluorescence (EDXRF) sourcing of 807 basalt artifacts and 34 basalt ecofacts recovered from stratified midden at Nu‘alolo Kai, Kaua‘i. These data are compared with EDXRF analyses of 473 alluvial pebbles from Waimea Canyon, 34 adzes from the Kaua‘i Museum, and published geochemical data for Kaua‘i basalts. Formal tools, such as adzes, chisels, and mirrors were predominantly manufactured from sources not available at Nu‘alolo Kai. Most adzes and chisels are consistent with sources available elsewhere on Kaua‘i, but two basalt mirrors are outside the expected geochemical range of Kaua‘i basalts. In contrast, almost all expedient tools were manufactured from basalts available at Nu‘alolo Kai. These findings support the existence of an island-wide distribution system for adze material on Kaua‘i, and challenges extant models of pre-contact Hawaiian economics to consider the mechanisms through which specialized commodities were produced and distributed.     

Drought as a Revelatory Crisis: An Exploration of Shifting Entitlements and Hierarchies in the Kalahari,Botswana

This article analyses drought in Botswana as a ‘revelatory crisis' in which structural contradictions as well as deteriorating socio-economic conditions are exposed. Paradoxically, however, drought also enables such conditions to be concealed because they can be attributed to the ‘crisis' and not to deeper problems and trends. In addition, crises such as droughts disrupt conventional routine sufficiently to allow actors (including government policy-makers as well as rural producers) to innovate with normative codes. This fact along with the opening up of structural fault lines often leads to accelerated rates of social change. Change is analysed here both in terms of the structural conditions in which it takes place (and alters) and with regard to the actions taken by individuals and institutions in order to reveal the links between structure and agency. The article draws upon an extended case study from Central Botswana and utilizes Sen's method of entitlement analysis to examine changing social processes.
