A new Miocene carnivorous marsupial,Barinya kutjamarpensis (Dasyuromorphia), from central Australia

Binfield, P., Archer, M., Hand, S.J., Black, K.H., Myers, T.J., Gillespie, A.K. & Arena, D.A., June 2016. A new Miocene carnivorous marsupial, Barinya kutjamarpensis (Dasyuromorphia), from central Australia. Alcheringa 41, xx–xx. ISSN 0311-5518.

A new dasyuromorphian, Barinya kutjamarpensis sp. nov., is described on the basis of a partial dentary recovered from the Miocene Wipajiri Formation of northern South Australia. Although about the same size as the only other species of this genus, B. wangala from the Miocene faunal assemblages of the Riversleigh World Heritage Area, northwestern Queensland, it has significant differences in morphology including a very reduced talonid on M₄ and proportionately wider molars. Based on the structural differences and the more extensive wear on its teeth, the central Australian species might have consumed harder or more abrasive prey in a more silt-rich environment than its congener, which hunted in the wet early to middle Miocene forests of Riversleigh.

Introduction to the Historical Archaeology of Powered Cultural Landscapes

This article starts by defining the term “powered cultural landscapes” and then provides a brief history of research on this topic in historical archaeology, starting with the settlement pattern paradigm that did not use the word “landscape,” and progressing to the landscape paradigm and the subsequent increasing use of the word “power” in cultural landscape research. Topics of research initially addressed landscape power dynamics between classes, followed by racial, ethnic, and finally gender power dynamics. Frameworks for analyzing power dynamics have progressed from the Marxian domination and resistance framework for class and racial power dynamics, followed by feminist analyses of male domination, to the recent development of a feminist inclusive heterarchical model of power dynamics.     

Play Nice or Pick a Fight? Cooperation as an Interest Group Strategy at Implementation

The open, multilevel nature of U.S. policymaking enables interest group activity throughout the policy process. At policy implementation, groups attempt to secure benefits or ameliorate legislated effects by devising cooperative or conflictual strategies to influence outcomes, especially when agency officials have discretion to design rules and negotiate agreements. Investigating group “street‐level” activity with respect to the Endangered Species Act, this research finds that policy context and resources shape the degree of information and access available to groups, which influences the strategies groups adopt. Groups with access and specialized information will attempt to change or influence policy outcomes cooperatively. Groups with limited technical information are more likely to fight implementation.     

Assessing the reliability of criteria used to identify mandibles and mandibular teeth in sheep, Ovis, and goats, Capra

Criteria developed to distinguish between the mandibles and mandibular teeth of sheep and goats are evaluated using modern specimens from the collections of the National Museum of Natural History and the Field Museum of Natural History. Certain teeth prove to be quite reliable in this regard (dP3, P3, P4). Other dental elements, however, are not reliable and should not be used in dental based identifications of these closely related species (dP4, M1, and mandibular bones). Overall, the identification of sheep dentition using these criteria is more reliable than it is for goats. However, the generally greater likelihood of incorrect identification of goat teeth and mandibles means that specimens identified as sheep are likely to contain high proportion of misidentified goats. Both the proportion of remains that can only be classified as ‘Ovis-Capra’ and the proportion of incorrectly identified teeth and mandibular bones varies with age, with identifications of younger and older animals less reliable than those of animals in the 1.5–6 year age range. Reliability of identifications increases when more criteria and more elements are used. Identifications based on whole mandibles with complete tooth rows are quite reliable. However, the proportion of specimens likely to be classified as ‘Ovis-Capra’ also increases in whole mandible identifications, especially in goats. Systematic differences in the proportions of indeterminate and incorrect identifications have a significant impact on species-level dentition-based harvest profiles. Recommendations are made for the use of dentition and long bone based harvest profiles in the study of sheep and goat exploitation strategies.     

Working in a Risk Society

Through much of the 1980s, discussions of transformations within work and employment debated the emergence of a new, more 'flexible' era - or, at a different level of analysis, the growth of more 'flexible' working practices. Recent accounts of contemporary socio-economic change have been framed within new sets of theoretical contexts, such as Ulrich Beck's notion of 'social risk'. The central aim of this paper is to evaluate the utility of such an approach, drawing upon empirical work which has investigated changes to terms and conditions of manual employment in British local authorities as a result of the introduction of compulsory competitive tendering.     

Southwest and northwest: Recent research at the juncture of the United States and Mexico

Research within the last 3 to 5 years is summarized for the southern part of the southwestern United States and adjacent northwest Mexico. In an effort to identify important new sources of information, the literature of contract archaeology is cited, along with more widely available journal and book publications. Topics considered include Late Archaic farmers, early ceramic villages, subsistence and agricultural technology, settlement stability and residential mobility, community organization, and developments of the late prehistoric period sociopolitical complexity.
