The Sticky Riff: Quantifying the Melodic Identities of Medieval Modes
Get PDFAndrew Hughes' Late Medieval Liturgical Offices afforded chant scholarship more melodies than it knew what to do with. Until now, chant scholarship involving 'Big Data' usually meant comparing individual feasts to the whole corpus or looking at general trends with respect to 'word painting' or stereotyped cadences. New research presented here, using n-gram analysis, networks, and Recurrent Neural Networks (RNN) looks to the nature of the gestural components of the melodies themselves. By isolating the notes preceding, and proceeding from, the naturally occurring semitones in the medieval church modes, we find significant recurrence of particular phrases, or riffs, which we propose could have been used to help 'build modes' from the inside out. Special care needed to be brought to the question of assumed B-flats that were not given explicitly in the manuscripts represented in Hughes' work. Understanding modes not as 'scales' but as a collection of associated smaller musical gestures, has resulted in a set of recurring riffs that appear as the identifiers of their larger contexts and confirming the influence of an earlier, oral / aural culture on these late medieval chants where musical literacy was expected.
Molecular Species Delimitation and Morphometry in the Melampus bidentatus (Panpulmonata, Ellobiidae) Cryptic Species Complex
No full textThe coffee bean snail Melampus bidentatus occurs in coastal salt marshes along the North American Atlantic and Gulf coasts, and the Caribbean. It was recently found that this large geographical span is actually occupied by a complex of three apparently cryptic species (preliminary called “North”, “South” and “Gulf”) with partially overlapping distributions. Until now it was not clear whether there are any morphological differences between the three species or which of the available names can be applied to which of the cryptic species. We used the already known distribution patterns of the cryptic species, as well as new barcode sequences to assign available names to the three cryptic species. We then compared morphological characters from 264 specimens using two approaches: an analyses based on 11 landmarks and another based on semi-landmarks of the entire shell outline. We were able to assign a nominal name to each of the three cryptic species: Melampus bidentatus for “North”, Melampus jaumei for “South” and Melampus gundlachi for “Gulf”. The morphometric analyses did not yield any diagnostic differentiating features; these cryptic species are hence diagnosible solely by genetic analysis, but may further phenotypically differ in some unseen internal features or in their physiology
A Picture is Worth a Thousand Words: Understanding our Students' Mathematical Experiences through Drawing
Get PDFLearning about our students’ perceptions of mathematics can help teachers better understand students’ mathematical efficacy and aid in the creation of lessons that foster positive mathematical learning experiences. In this article, we share some students’ perceptions of doing mathematics through their drawings. We looked at students from three different grade levels in three different countries: China, Fiji, and the United States. We discuss what we learned from these drawings as teachers and how teachers can use the drawing task to learn more about their student’s perceptions of doing mathematics
Prison-Based Economic Development: What the Evidence Tells Us
Get PDFSince the late 1970s, there have been significant increases in the number of prisons and prisoners held in small towns and rural areas in the United States. Rural small towns have used prison construction and management as an economic development strategy. Although prisons were once seen as misfortune and disappointment to residents, since the 1980s, prison hosting has become a last resort for impoverished rural towns with desperate need of jobs. Prisons have been expected to fill the void when local industries and businesses closed down their operations in the 1980s economic crisis. While mass imprisonment and the prison boom in the United States have been important topics of research in the criminal justice field, less is known about prison-based economic development and its effects on local economies. This study conducts a literature review of U.S. studies, discusses theoretical and empirical limitations in the literature, and offers implications for research and policy development

Understanding Factors Leading to Farmer Non-compliance with Agri-food Safety Regulations in Kenya: A Quantitative Analysis
No full textThis article presents the findings of a study that examined the factors that influence farmers’ compliance decisions concerning agri-food safety laws in Kenya. A total of 160 farmers in Uasin Gishu County in Kenya were surveyed using semi-structured interviews. Twelve variables were used to test the associations between farmer demographics, instrumental and normative factors as independent variables and agri-food safety regulatory compliance as dependent variable. Regression analysis revealed that deterrence factors, farmer training and extension services, and legitimacy factors are significantly related to farmers’ compliance with agri-food safety regulations. These findings suggest that regulators should not only focus on enforcing and tightening regulations but also improve the provision of training and information on agri-food safety regulations for farmers. Furthermore, additional efforts should be directed to making laws simpler, clearer, relevant and appropriate for farmers
Reading a legacy of black gay literature in/to Disability Studies and a Crip-of-Color Theory: Exploring the work of Joseph Beam, Essex Hemphill and Audre Lorde
No full textThis article reads works of Audre Lorde, Essex Hemphill, Joseph Beam, and other writers through what I name a palimpsestic practice of crip reading . The very way in which we must find and read the voices of Black gay men is by locating anthologies and reading those contributors in palimpsestic relationship to one another and to Black feminist writers and organizers. Although Black gay men and Black feminists of the 1980’s and 1990’s engaged with cancer and HIV in their writings, they are often considered as part of different political, cultural, and intellectual legacies than is often included in the field of Disability Studies. A palimpsestic reading of their works as entangled with each other reveals new genealogies of crip activist and cultural work. By this I mean that Black queer and/or feminist writing exist in a palimpsest relationship with Disability Studies; one can read the layers of thought through one another. A palimpsestic reading also proposes that cultural workers presumed to be outside the sphere of Disability Studies are, in fact, central to creating a crip-of-color theory
