Energy source,protein metabolism,and hunter-gatherer subsistence strategies

During late winter and spring, hunter-gatherers in temperate, subarctic, and arctic environments often relied on diets that provided marginal or inadequate caloric intakes. During such periods, particularly when stored food supplies dwindled or were used up entirely, lean meat became the principal source of energy. Nutritional problems associated with high-protein, low-energy diets are discussed. These problems include elevated metabolic rates, with correspondingly higher caloric requirements, and deficiencies in essential fatty acids. The relative benefits of adding fat or carbohydrate to a diet of lean meat are evaluated in light of the protein-sparing capacities of these two nutrients. Experimental data indicate that although both enhance high-protein, low-energy diets, carbohydrate is a more effective supplement than fat. Given the nutritional inadequacies of a lean-meat diet, the paper concludes with a discussion of alternative subsistence strategies that increase the availability of carbohydrate or fat at the critical time of year.     

The saint as patron in the work of Gregory of Tours

Gregory of Tours and his world have long been out of fashion; but despite modern neglect of his works, Gregory gives us access to an understanding of many important aspects of late antiquity, among which is the role of the saint as patron. Saints appear as patrons throughout Gregory's works; the focus of this study is his account of the miraculous deeds of St. Martin. The role of the saint as patron is best understood against the background of the recent work of Peter Brown on holy men in late antiquity; several other scholars have also emphasized the importance of patrons in the Roman world. Appeals to the saints in Gregory's world are to be understood as one manifestation of the Roman ritual of appeal to a patron. More important than their afflictions are the social circumstances of those who appeal to St. Martin and analyzing some others in detail, we can demonstrate that the most important elements in those appeals are the social weakness of the appellants, their need for a saintly patron, and Martin's role as a model saintly patron in Gregory's world     

“A log-rolling,Irish-American politician,out to raise votes in the United States”: Tip O’Neill and the Irish dimension of Anglo-American relations, 1977–1986

The Irish dimension of Anglo-American relations is a relatively marginalized aspect of the historiography of transatlantic studies. Historians have focused on the role of the Clinton administration in the Northern Ireland “peace process” but previous American contributions also warrant attention. As the Speaker of the United States House of Representatives, Thomas P. “Tip” O’Neill was one of the most prominent Irish-American politicians. This article demonstrates O’Neill's attempts to ensure that the American contribution to the Anglo-Irish process steadily increased, despite the transition from arguably his natural political ally in the President Jimmy Carter administration to President Ronald Reagan in 1981. O’Neill's interest in Northern Ireland and position as speaker helped ensure that Carter's promise of financial aid to Northern Ireland in 1977 following progress in the political process was fulfilled in March 1986.     

Quantifying Animal Trajectories Using Spatial Aggregation and Sequence Analysis: A Case Study of Differentiating Trajectories of Multiple Species

The increasing availability of telemetry data with high spatial and temporal resolution promises to greatly advance scientific understandings of the movement patterns of individual organisms across space and time. The amount of data provided by such methods, however, can be challenging to analyze and interpret. In this study, we present a new approach for analyzing animal movements that aggregates telemetry locations into spatial clusters and extracts the information from sequences formed by individuals passing through these spatial clusters. We applied this integrated approach of spatial aggregation and sequence analysis to quantify and compare trajectories of cattle (Bos taurus), mule deer (Odocoileus hemionus), and elk (Cervus elaphus) tracked by automated telemetry at the Starkey Experimental Forest and Range in northeastern Oregon, USA. Our approach effectively differentiated movement patterns of the three species. It provides a useful mean of quantifying movement patterns of species in a landscape.
