Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia

Benson, R.B.J., Fitzgerald, E.M.G., Rich, T.H. & Vickers-Rich, P., 2013. Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia. Alcheringa 37, 1–6. ISSN 0311-5518

We report a large plesiosaurian tooth from the freshwater early–middle Aptian (Early Cretaceous) Eumeralla Formation of Victoria, Australia. This, combined with records of smaller plesiosaurian teeth with an alternative morphology, provides evidence for a multitaxic freshwater plesiosaurian assemblage. Dental and body size differences suggest ecological partitioning of sympatric freshwater plesiosaurians analogous to that in modern freshwater odontocete cetaceans. The evolutionarily plastic body plan of Plesiosauria may have facilitated niche differentiation and helped them to exclude ichthyosaurs from freshwater environments during the Mesozoic. However, confirmation of this hypothesis requires the discovery of more complete remains.

‘I've had it with them!’ Younger migrant women's spatial practices of conformity and resistance

This article examines how younger migrant women from Turkey maneuver the public and private spaces of their everyday lives in a neighborhood in Germany, and how they challenge and affirm the patriarchal practices and gender norms that husbands, fathers, and older migrant women seek to impose within and outside private homes. Younger migrant women selectively comply with gendered and generational norms of veiling and dress, while at the same time also reworking gender roles, and avoiding and transgressing masculinist spaces. Younger migrant women's practices and spatial representations in mental maps reveal the complex entanglements of compliances and resistance, and dispel simple assumptions of being overwhelmingly victimized by their potentially violent men that are so prominent in contemporary Western societies.     

Constitutionalism or Staatssreich? Bismarck,Crown Prince Frederick William,Crown Princess Victoria and the Succession Crisis of 1880-85

Though Otto von Bismarck exercised great power as Chancellor of the German Empire, historians have overlooked the extent to which it was threatened during the 1880s by the imminent accession of Crown Prince Frederick William. The article focuses on the means by which Bismarck strove to maintain his power, and how many of his plans were thwarted by the crown prince. The heir to the throne had to also fend off his wife's campaign to enact radical liberal reforms during her husband's coming reign. The ability of the crown prince to resist the campaigns of both his wife and Bismarck shows that his influence was indeed considerable, and that estimates of Bismarck's power are in need of revision.     

Long-term agrarian landscapes in the Troodos foothills,Cyprus

We investigate the temporal and environmental relationships between the terraced hill slopes of Politiko-Koloiokremmos and the adjacent Bronze Age settlement of Politiko-Troullia in foothills of the Troodos Mountains, central Cyprus. Mapping of 102 stone walls on Koloiokremmos is compared with 66 walls farther afield on Cyprus to create a six-part terrace typology. Sherd counts from 174 2-m radius collection circles over approximately 20 ha on Troullia and Koloiokremmos were used to create interpolated sherd density surfaces revealing distinctly different patterns of land use for four major archaeological eras between the Cypriot Bronze Age and Medieval Period. We compared sherd density patterns according to terrace types, length, slope and vegetation cover determined by SAVI (Soil-Adjusted Vegetation Index) from Ikonos and Quickbird satellite imagery.The most robust sherd patterning indicates Prehistoric Bronze Age settlement at Troullia, as confirmed by soil resistivity and excavation, and multi-period land use on Koloiokremmos immediately upslope of the village that may be associated with agricultural terracing. Scattered sherd concentrations indicate later use of this landscape as an agricultural hinterland for the Iron Age city of Tamassos. Sherds and a down slope spread of roof tiles from the Roman through Medieval periods suggest an isolated structure near the crest of Koloiokremmos. Longer terraces correlate with greater vegetation cover and are interpreted as agricultural, while shorter terraces, apparently for erosion control and arboriculture, are significantly related to Prehistoric Bronze Age sherd patterns. Our results suggest that coordinated analysis of archaeological, geographical and remotely sensed environmental data associated with terraced landscapes can be used to infer long-term patterns of agricultural land use.     

Enacting power through networks

We argue here that processes of political centralization and hierarchy building can be profitably explored by focusing on how resources were strategically manipulated in search of power by people organized in social networks of varying sizes and spatial extents. Adopting this perspective encourages reconsideration of the ways in which such core concepts as structure, agency, and society can be redefined to cast new light on ancient power contests. In addition, we suggest that a network approach complements traditional emphases on processes of domination and resistance by drawing attention to the importance of alliances in shaping political formations. The potential utility of these precepts is illustrated in an example drawn from our research on Terminal Classic (800–1000 AD) political struggles in the Naco valley of northwestern Honduras. Special attention in this case centers on the manner in which craft products were manipulated by people of varying ranks to define and achieve goals as well as to control the actions of others. The study’s broader implications for the analysis of ancient political relations are highlighted at the essay’s conclusion.     

PATTERNS AND DETERMINANTS OF PRODUCTIVE EFFICIENCY IN STATE MANUFACTURING*

ABSTRACT This paper uses a stochastic frontier production-function model to measure and compare productivity efficiency in the manufacturing sector of states in the United States over the period 1959–1972. Based on this model we find considerable variations in productive efficiency across states. A large portion of the variation is found to be related to regional differences in labor-force characteristics, levels of urbanization and industrial structure. We also examine the relationship between productive efficiency and the subsequent growth of manufacturing and find some evidence of a weak relationship between efficiency and the growth of employment.
