    Langford sequences and a product of digraphs

    Skolem and Langford sequences and their many generalizations have applications in numerous areas. The ⊗h\otimes_h-product is a generalization of the direct product of digraphs. In this paper we use the ⊗h\otimes_h-product and super edge-magic digraphs to construct an exponential number of Langford sequences with certain order and defect. We also apply this procedure to extended Skolem sequences.Comment: 10 pages, 6 figures, to appear in European Journal of Combinatoric

    Broadening Our Understanding of Noble-Wieting: A Langford Tradition Village in Central Illinois

    The Noble-Wieting site is an Upper Mississippian Langford Tradition village and burial mound, located in east-central Illinois on the outskirts of the Langford Tradition region and distant from other known Mississippian villages. Archaeological excavations at Noble-Wieting during the 1960s and 1970s unearthed features within limited sections of the site, leaving a large portion unexplored. Excavations revealed a higher than average percentage of shell-tempered Middle Mississippian pottery as compared to other Langford villages, giving rise to questions regarding internal changes of cultural identity and suggestions of isolation from contemporary communities. However, the 1976 excavations in the southern portion of the site had yet to be processed, leaving a gap within the archaeological record that could prove initial conclusions inconsistent with material culture. This project examines concepts of changing cultural identity while broadening the understanding of the external social interactions between Langford and Mississippian groups in the borderland region. In this thesis, the unprocessed excavation data from 1976 was analyzed and compiled with previous data to present an expanded view of the internal composition of the site and distribution of material culture. Material analysis resulted in a smaller proportion of shell-tempered ceramics at the site than previously concluded and no other Middle Mississippian artifacts, which suggests interaction with or influence from those groups was more limited than hypothesized for this thesis. However, the percentage of 18.75% of shell-tempered ceramics remains higher than most Langford villages. Examination of the surrounding area led to identification of other Langford sites, such as the nine Hinshaw A sites, thus revealing less isolation from other Langford people than has been suggested. GIS mapping was created to highlight other possible habitation locations within the east-central Illinois area. Advancing the interpretations of this site’s spatial and material culture relation within its own borders, as well as its connections to contemporary Langford and Middle Mississippian peoples in the surrounding area, contributes to the field of archaeology’s foundational knowledge for the Langford Tradition and for understanding changes in cultural identity along border regions between cultures

    “Dear Friend and Sister”: Laura Holloway-Langford and the Shakers

    Get PDF
    For more than fifty years, Laura Holloway-Langford and the Mount Lebanon Shaker community sustained a complex relationship which has been preserved in correspondence written between 1874 and 1926. In her prime, Holloway-Langford was well known as an author, a supporter of progressive cultural and social causes, and an advocate for unconventional religious ideas. In 1906, she purchased the Upper Canaan farm from the Mount Lebanon Shakers, initially intending that it become a spiritual retreat. It was only after the deaths of her closest Shaker friends that Laura Holloway-Langford left Brooklyn to make her home on this property, where she died in July 1930, in obscurity, isolation and poverty

    A Paleoethnobotanical Comparison of Mortuary and Village Langford Tradition Sites in Northern Illinois

    Get PDF
    Archaeologists working in northern Illinois have conducted research on Langford Tradition (ca AD 1100-1450) sites for more than a century. The last 40 years have seen increasing methodological sophistication providing for a relatively nuanced understanding of food technology and resource use. Paleoethnobotany has provided one way to observe the diversity of plant use among Langford site occupants. Using standard paleoethnobotanical practices, plant macroremain from the Robinson Reserve Site (11CK2) are analyzed. The results of the plant macroremain analysis are then compared to existing floral data from the Washington Irving Site (11K52). This research investigates whether site functionality is distinguishable between Langford tradition mortuary and village sites
