Midden or Molehill: The Role of Coastal Adaptations in Human Evolution and Dispersal

Coastal adaptations have become an important topic in discussions about the evolution and dispersal of Homo sapiens. However, the actual distribution and potential relevance of coastal adaptations (broadly, the use of coastal resources and settlement along shorelines) in these processes remains debated, as is the claim that Neanderthals exhibited similar behaviors. To assess both questions, we performed a systematic review comparing coastal adaptations of H. sapiens during the African Middle Stone Age (MSA) with those of contemporaneous Neanderthals during the European Middle Paleolithic. In both species, systematic use of marine resources and coastal landscapes constitutes a consistent behavioral signature over?~?100,000 years (MIS 6–3) in several regions of Africa and Europe. We found more similarities than differences between Neanderthals and modern humans, with remaining disparities all in degree rather than kind. H. sapiens exploited a wider range of marine resources—particularly shellfish—more intensively. MSA shellfish-bearing sites are also more often associated with intense occupations on coastal landscapes, and more evidence of complex material culture such as shell beads. In terms of broader ramifications, Pleistocene coastal adaptations are best conceived of as an ‘add-on’ to previous adaptive strategies, complementing more frequently exploited inland resources and landscapes. Still, Neanderthals and modern humans increased their dietary breadth and quality, and added options for occupation and range expansion along coastlines. Potential evolutionary implications of these multi-generational behaviors include higher intakes of brain-selective nutrients as a basis for neurobiological changes connected to increased cognitive capacities, but also greater reproductive success, dispersal abilities and behavioral flexibility. Whether gradual differences between modern humans and Neanderthals stimulated different evolutionary trajectories is a question for future research.

     

Telling off Justinian: Theudebert I,the Epistolae Austrasicae,and communication strategies in sixth‐century Merovingian–Byzantine relations

The death of the powerful Frankish king Theudebert I (r. 533–47) gave rise to a diplomatic imbroglio between the courts of the eastern emperor Justinian, who condemned the late king, and Theudebert's son and successor Theudebald, who aggressively defended his father's memory. This dispute provides two opportunities: first, to parse the sixth‐century sources into separate political discourses; and secondly, to examine the diplomatic letters of Theudebert and Theudebald, preserved in the Gallic letter collection Epistolae Austrasicae, as evidence for creative experimentation with the genre of letters, expanding the functions and forcefulness of the basic media of long‐range communication.     

Degrading and Managing Risk: Assessing Australia's Counter-Terrorist Strategy

Given the occasionally vexatious nature of academic discussion in Australia on the subject of terrorism, it is surprising that so little has been written regarding Australia's approach to countering terrorism. This gap in the literature stands in marked contrast to the highly charged debate over the direction of terrorism studies in this country. In seeking to fill this lacuna, the article critically examines the three essential pillars of Australia's counter-terrorism strategy that have evolved since 2001: domestic legislation, intelligence, and regional assistance and engagement. I argue that Australia's counter-terrorist strategy exhibits greater cohesion than many of the critics have been willing to acknowledge. However, I also argue that there remain significant flaws in the Howard government's approach, particularly as it relates to a lack of transparency in justifying new anti-terrorism legislation and Australia's unswerving support for a US global counter-terrorism strategy that has lost its way since the invasion of Iraq in 2003.     

Investigation of Iron Age north-eastern Scottish glass beads using element analysis with LA-ICP-MS

Class 13 and 14 Iron Age Scottish glass beads are a group of highly decorated beads of British origin or design, dating indicatively to the 1st and 2nd century AD and typically found in Aberdeenshire and Moray district (Guido, 1978, 85–9). Their distinctive stylistic characteristics and geographical segregation renders them ideal for the investigation of whether the glasses employed in their manufacture were imported rather than produced locally, and for the assessment of the technology used in the production of the deep colours. Studies performed in the 1980s on different specimens pertaining to the same Classes (Henderson, 1982) showed compositional characteristics differing from Iron Age southern British beads, suggesting a different source of glass for their manufacture. Here, a set of 19 beads which was never investigated before was analysed for 32 major, minor and trace elements using Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The sample set shows good homogeneity in major and minor element composition, indicating the use of imported natron glass, with standardized composition typical of Roman glass of the period, also reflected in the recipes used for colouration. Evidence for the use of cullet and waste glass was found, which, along with the particularity of the design, suggests a local origin of the beads and possible production by native glassworkers.     

Variation in collagen stable nitrogen values in black-tailed jackrabbits (Lepus californicus) in relation to small-scale differences in climate,soil, and topography

Longstanding observations about the relationship between increasing aridity and ¹⁵N enrichment in mammalian collagen values have led to an interest in their use as a paleoclimatic marker. Here we report on variability in collagen nitrogen values from five modern and two archaeological samples of black-tailed jackrabbits (Lepus californicus) from the eastern Great Basin of the United States (N = 178 individuals). Nitrogen δ¹⁵N values were highly variable within all samples. Modern samples showed significant differences despite similarities in average annual precipitation and temperature. Archaeological samples were indistinguishable from each other or from modern samples taken from the same area despite independent evidence for differences in precipitation for the two prehistoric periods considered. Differences between modern samples were most strongly associated with soil characteristics. We discuss these results in light of their relationship with topography and vegetation and highlight their implications for archaeological applications of stable nitrogen analyses in several contexts.     

Hematite sources and archaeological ochres from Hohokam and O’odham sites in central Arizona: an experiment in type identification and characterization

The use of ochre is a defining characteristic of populations living in the Sonoran Desert of the American Southwest. Red pigments and paints were used for craft production, bodily adornment, rock art, and in mortuary contexts. Hematite and other iron-oxides are common components of this pigment that frequently appear in the archaeological record in a variety of forms and in various stages of production. Beyond this, very little is known about these materials. This paper describes the collection of potential geological sources of ochre in the Phoenix Basin and presents a methodology for the identification of processed paints. Geological sources samples are characterized using instrumental neutron activation analysis (INAA) and compared to raw materials recovered archaeologically from the Gila River Indian Community reservation. This preliminary study indicates that iron-oxide sources can be distinguished from each other and that artifacts can be matched to these sources, revealing local procurement along the Gila River by Hohokam and O’odham artisans and continuity in use of one source from the prehistoric period to the present.     

HISTORY AND KAIRÓS

The recent wave of interest in the “theological‐political” has focused scholarly attention on the constellation of ideas associated with “messianic time.” The term kairós belongs to this constellation, and Giacomo Marramao's brief but ambitious text of the same name both proposes and performs a “kairological” reconfiguration of the close relationship between philosophy and time. Marramao's argument for the productive potential of “cosmic disorientation” and contingency will merit the attention of historians interested in Benjamin's blend of messianism and historical materialism, and of anyone who is intrigued by the prospect of a messianism without apocalypticism.     

DO LOCATION‐BASED TAX INCENTIVES ATTRACT NEW BUSINESS ESTABLISHMENTS?*

ABSTRACT This paper examines how offering tax incentives in a local area affects the entry of new business establishments. We use the federal Empowerment Zone (EZ) program as a natural experiment to test this relationship. Using instrumental variables estimation, we find that the EZ wage tax credit is responsible for attracting about 2.2 new establishments per 1,000 existing establishments, or a total of 20 new establishments in EZ areas. New establishment growth is strongest in the retail (about 40 new establishments) and service (about five new establishments) sectors, and offset by declines or slower growth in other industries.     

Logging,Violence and Pleasure: Neoliberalism,Civil Society and Corporate Governance in West New Britain

ABSTRACT The postcolonial world of Melanesia is made up of diverse experiments, which combine modern and customary technologies of power into new hybrid assemblages. In the 1990s, there occurred a proliferation of landowner companies in rural New Britain. This happened in a context of neoliberalism where the state divested itself of many functions and services by allocating these to a supposedly more efficient private sector. In the Kaliai area, this new economic partnership between state and capital gave rise to more militarised forms of policing, which sought to protect logging by a large Malaysian company from growing local unrest. Supplementing these coercive state actions were private strategies, which used sorcery to intimidate opponents to logging as well as rivals within the landowner company. Opponents were bought off and alliances created through using customary exchange relations as well as through modern gifts of money, western goods and commoditised pleasures.     

An Analysis of Arrow and String Bag Craft Variability in the Upper Sepik and Central New Guinea

ABSTRACT This paper describes an analysis of relationships between language, geography and material culture in the upper Sepik region of New Guinea. We used Mantel tests and principal coordinate analysis to assess and compare the associations between arrow and string bag crafts and language and geographical distance. The Mantel tests resulted in a significant association between each class’ craft variability and both geographical distance and language, however, after statistical control was applied to either of the independent variables only a significant association with geographical distance remained. We argue that these results indicate craft techniques were readily disseminated and that craft distributions are unlikely to reflect any deeper historical relationships between groups. The spatial autocorrelation of arrow crafts was particularly great. A comparison of the principal coordinate analysis plots indicates a greater degree of diffusion and synthesis had taken place between lowland and highland arrow craft traditions. We conclude that the more intensive learning regimes needed to master string bag craft techniques, as well as a greater degree of interdependence between string bag components, had ensured more abrupt differences between bag types resulting in a more moderate degree of spatial autocorrelation.
