Evaluating Ancient Whale Exploitation on the Northern Oregon Coast Through Ancient DNA and Zooarchaeological Analysis

Whales have long been an important part of Pacific Northwest Coast human subsistence and lifeways. Native peoples on the Oregon Coast were not known to hunt whales, but a humpback whale phalange with an embedded bone harpoon at the Par-Tee site (35CLT20) and ethnographic accounts raised the possibility of opportunistic whale hunting. We analyzed a suite of whale remains from Par-Tee and performed ancient DNA-based species identifications on 30 specimens. The assemblage includes gray whales (Eschrichtius robustus, 60.7% of the assemblage), humpbacks (Megaptera novaeangliae, 32.1%), minkes (Balaenoptera acutorostrata, 3.6%), and orcas (Orcinus orca, 3.6%). While the species composition is similar to those found in archaeological deposits from systematic whaling areas in Washington and Vancouver Island, bone modification patterns and element representation reveal important differences. Our analysis demonstrates that whales were likely a supplementary part of human subsistence at Par-Tee and, while opportunistic whale hunting likely occurred, it may have been secondary to scavenging and utilization of beached and/or drift whales.     

Low-Level Food Production

Societies with low-level food production economies occupy the vast and diverse middle ground between hunting–fishing–foraging and agriculture. Efforts by Ford, Harris, Rindos, Zvelebil, and others to characterize this in-between territory are discussed, and a new conceptual framework is proposed. Domestication, the central landmark of this middle ground, is situated well away from the boundaries with hunting–gathering and agriculture, and separates low-level food production economies into two broad categories. Key issues and questions concerning societies with low-level food production, both with and without domesticates, are discussed. Hunter–gatherer and agriculture boundary zones on either side of the middle ground are considered, as are the developmental pathways that traverse them.     

西江中游文化区的生业经济及其发展阶段

西江中游地区是岭南历史文化区内一个相对独立的考古学文化区,新石器时代大致经历了三种生业经济形态,早期是一种广谱的渔猎采集经济,中期是一种利用贝类为主的渔猎采集经济,晚期是较发达的稻作农业经济。演进过程在整个文化区内具有一致性。贝类利用自新石器时代早期开始呈现出一种显著强化的趋势,但一直未在食物结构中占据主要地位。     

The Determinants of Policy Introduction and Bill Adoption: Examining Minimum Wage Increases in the American States, 1997–2006

Faced with long intervals between federal minimum wage increases in recent years, state legislatures are increasingly likely to take action. Motivated by the relative dearth of empirical work on minimum wages in the American states, this article considered various explanations to determine which factors are associated with legislative efforts to pass wage increases. Taking seriously the view that disagreements over the effects of minimum wage increases enhances the influence of political factors, we drew on the policy adoption and diffusion literature to examine how internal determinants (political and economic variables) and regional diffusion pressures relate to both the introduction and adoption of minimum wage legislation in the American states in the years between the last two federal minimum wage increases (1997–2006). Employing negative binomial regression to analyze annual bill introductions, we found that a number of political variables are related to the consideration of minimum wage increases. However, using event history analysis to examine annual adoptions of minimum wage increases, we found few of the same variables matter. We concluded with a discussion of the empirical results within the context of the broader policy literature and cautioned future scholars to consider seriously whether political factors exert distinct influences at different stages of the policy process.     

The Archaeology of Global Encounters Viewed from Banda, Ghana

West African societies have long been enmeshed in interregional, subcontinental, and intercontinental relations. Documents tell us little about how local life was shaped by its intersection with global processes, especially in coastal hinterlands. In this paper I report on archaeological investigations into the changing contours of local life in the Banda area of west central Ghana over the past seven centuries. Excavations at three temporally distinct occupations on two sites—Makala Kataa and Kuulo Kataa—document changes in settlement, craft production, subsistence, and exchange, providing insights into the dynamics of local life during a period of expanding global networks. A concluding section addresses why this type of research is important for our understanding of ancient African societies. Les sociétés Ouest Africaines sont depuis longtemps parties prenantes dans les relations inter-régionales, sous-continentales et inter-continentales. Les documents ne nous disent pas grand chose sur la manière dont la vie locale a été façonnée par cette interaction avec les processus mondiaux, particulièrement dans les arrières pays côtiers. Dans cet article, je rends compte des recherches archéologiques concernant les changements dans la vie locale intervenus dans la région de Banda au centre ouest du Ghana au cours des sept derniers siècles. Les fouilles dans trois occupations temporellement distincts sur deux sites—Makala Kataa et Kuulo Kataa—mettent en évidence les changements dans l'occupation, la production artisanale, les modes de subsistances et les échanges, donnant un aperçu des dynamiques de la vie locale durant une période d'expansion des réseaux mondiaux d'échange. La conclusion aborde les raisons pour lesquelles ce type de recherche est important pour notre compréhension des anciennes sociétés africaines.
