Welfare Reform and Economic and Housing Capacity for Low-Income Households, 1997–1999

The 1996 Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) marked the continued devolution of social policy to state and local government in addition to restructuring an ailing welfare system. Despite concerns that welfare recipients would find greater obstacles to economic stability as a result, declining welfare rolls have been accompanied by declining poverty rates over the past seven years. An important question is whether low‐income families have gained greater employment and housing capacity following welfare reform. Moreover, does capacity vary across states with different welfare policies? In addition, do families face greater economic vulnerability with respect to food scarcity and health care? This article uses the data from the 1997 and 1999 waves of the National Survey of America's Families to systematically assess differences in capacity and vulnerability among lower income families across different policy regimes. Using two measures of capacity for housing and employment, and quality of life, findings suggest that more stringent welfare rules are related to greater job and housing attainment but a reduced quality of life.     

The Archaeology of California

Stimulated by several important, recent empirical advances, California archaeologists are engaged in a series of lively debates. These advances include new discoveries about the early peopling of western North America and sustained occupation of the California coasts as early as 12–13,000 BP. There also have been significant new developments in the role of paleoenvironmental change in cultural evolution, the emergence of long-distance interaction spheres, the presence of intensive craft specializations, and the appearance of sociopolitically complex hunter–gatherers. This article addresses these issues—and several others—with a view to the general interests of scholars worldwide. The exceptional heterogeneity of California ecosystems (from deserts to dense redwood forests to bountiful offshore islands) and the remarkable cultural diversity exhibited by the dozens of major groups who made these lands their home combine to produce a complex indigenous sociopolitical picture. Current understandings reveal myriad trajectories of cultural change across nine major subregions of the state.     

A probable ankylosaurian (Dinosauria,Thyreophora) from the Early Cretaceous of New South Wales,Australia

Bell, P.R., Burns, M.E. & Smith, E.T. October 2017. A probable ankylosaurian (Dinosauria, Thyreophora) from the Early Cretaceous of New South Wales, Australia. Alcheringa 42, 120–124. ISSN 0311-5518.

We describe an isolated osteoderm from the Albian Griman Creek Formation where it is exposed near the town of Lightning Ridge in central-northern New South Wales, Australia. Several lines of evidence allow referral of this element to the Ankylosauria—a group that epitomises body armour and ubiquitous osteodermal coverage among dinosaurs. Despite the abundant record of fossil vertebrates from this interval, ankylosaurians have not been previously reported, although, they have been described from penecontemporaneous deposits in western Queensland and Victoria. This discovery, therefore, provides an important link between the northerly faunas (including the Griman Creek Formation) that flourished at the edge of the epeiric Eromanga Sea, with those from the sub-polar rift-valley system of Victoria during the mid-Cretaceous.

Which Bone to Pick: Creation,Curation, and Dissemination of Online 3D Digital Bioarchaeological Data

A fluorescence of shape-capture technologies at many different scales, including synchrotron, CT, micro/nano-CT, laser scanning, and photogrammetry, has led to a proliferation of digital data in bioarchaeology. The question remains how these new 3D datasets, alongside traditional bioarchaeological data, can be disseminated, and what ethical concerns are raised by trying to bring a sensitive topic into the ‘Open Access’ era. A survey of current resources and policies suggest the need for establishing best-practice standards. This paper outlines a sample of current resources, alongside modes of access and dissemination strategies to develop a picture of online Digital Bioarchaeological Data (DBD) use.     

Neutron activation analysis of stone from the Chadron Formation and a Clovis Site on the Great Plains

Cryptocrystalline silicates from the Chadron Formation were widely used by prehistoric human groups in the Great Plains of North America. There are two documented quarry areas: Flattop Butte in Colorado and the White River Badlands of South Dakota. Cryptocrystalline silicates from these sources are visually indistinguishable, making it difficult to determine the sources of artefacts found at archaeological sites. In this investigation, neutron activation analysis is used to distinguish the two sources. This technique also identifies lithic material from the Clovis-age Eckles site in Kansas as being from Flattop Butte.     

THE POSSIBLE FRACTIONATION OF LEAD ISOTOPES IN ANCIENT METALLURGICAL PROCESSES

The possibility of lead isotope fractionation in ancient lead production is examined. Kinetic theory relating to isotopic fractionation in non-equilibrium evaporation is considered and the feasibility of the alteration of lead isotope abundance ratios in ore roasting and smelting is assessed. Previous experimental work is shown to have been inconclusive and conclusions are drawn on the need for further research to quantify the possible extent of fractionation in practice.     

Three geographers in an archive: positions, predilections and passing comment on transient lives

Despite the existence of research conducted by geographers eschewing or professing religious faith, the influence of researchers and their methods have yet to receive critical attention within the study of religion. The experience of three geographers working on a three-year research project suggests that it is vital to reflect upon the inter-subjective relationships and methodologies used to reconstruct the religious past. How do different subject positions influence our selections from historical records? We also consider whether the spatialities of putatively 'religious' archives, whether formally or informally constituted, make a difference to the construction of historiographical knowledge. In attempting to answer these questions, the paper argues that developing an awareness of different types of positionality, vis-à-vis religious faith and practice, combined with reflexivity, vis-à-vis methodology, can enrich the interpretative reconstruction of the religious past.     

Metropolitan Income Inequality During the 1980s: The Impact of Urban Development, Industrial Mix, and Family Structure

The empirical analysis in this paper explores the interurban variation in family income distribution. The results point to increasing urban development, rising female-headship, a widening educational distribution, and changes in the industrial and occupational mix as major contributing factors to rising inequality. However, the increase in the relative number of multiple worker families was a significant mitigating force to rising inequality. A decomposition of 1979 and 1989 cross-sectional models revealed that while changes in urban family and industrial characteristics have been sources of rising inequality, there has been significant structural change in the urban models acting to decrease inequality.     

Macrophysical climatic modeling of Africa’s late quaternary climate: Site-specific, high-resolution applications for archaeology

Macrophysical climatic modeling (MCM) is based on the relationship between large-scale atmospheric dynamics and synoptic climatology to develop simulations of late Pleistocene and Holocene climate in specific localities. Climatic events are calculated at 200-year intervals for the last 14,000 and 500 years for the period from 14,000 to 40,000 B.P. The model has been applied to more than 200 localities in Africa. We present examples from different parts of the continent at locations of archaeological significance. The results indicate that the transition from glacial maximum to postglacial conditions shows both temporal and inter- and intraregional variability. In addition to long-term differences among early, middle, and late Holocene climatic regimes, the model also shows incidences of sharp, abrupt events at some intervals. The applications of MCM invite comparison with inferences based on proxy data and assist in formulating and cross-examining socioecodynamic models based on climatic change, e.g., the continuity of cultural interactions along the Mediterranean littoral, the emergence and spread of cattle pastoralism, and the depopulation of the Sahara during the glacial maximum.
