Clarifying The Ploidy Of Some Accessions In The Usda Alfalfa Germplasm Collection, Muhammet Şaki̇roğlu, Edward Charles Brummer

Turkish Journal of Botany

Cultivated alfalfa was selected from a complex taxonomic group called the Medicago sativa-falcata complex. The complex includes a number of diploid (2n = 2x = 16) and tetraploid (2n = 4x = 32) taxa. Prior information of ploidy is vital for the effective utilisation of genetic resources in alfalfa breeding programs. From the US National Plant Germplasm System, we obtained the seeds of 256 wild accessions thought to be from the 3 diploid subspecies included in the M. sativa-falcata complex, in order to determine their ploidy level using flow cytometry: M. sativa subsp. caerulea, M. sativa subsp. falcata, and M. …

A Comparative Assessment Of Fruit Formation In Some Orchid Species From The Southern Caucasus Region, Houshang Nosrati, Roghieh Hajiboland, Ahmad Razban-Haghighi, Maryam Nikniazi

Turkish Journal of Botany

The distribution and population size of 5 orchid species (Cephalanthera longifolia, Orchis simia, Platanthera bifolia, Dactylorhiza romana, and Ophrys scolopax) were studied in the southern Caucasus based on the individual numbers in a given area. The fruit set was recorded for the latter 3 species and compared in natural and control groups (pollinators prevented) for D. romana and O. scolopax. We compared the obtained fruit set values with those reported from other regions. The distributions of the 5 species were completely fragmented and the population sizes were extremely small. This is the first report of O. scolopax from the region, …

A Proposed Theoretical Model Of Literacy Learning Using Multisensory Structured Language Instruction (Msli), Judith E. Rusinko

Antioch University Dissertations & Theses

Multisensory Structured Language Instruction has been used for decades by clinicians and practitioners as an intervention for teaching students with dyslexia. Multisensory Structured Language Instruction uses the integration of multiple senses (visual, auditory, and kinesthetic/tactile) simultaneously to teach literacy. Although the anecdotal evidence for Multisensory Structured Language Instruction is strong, there is a lack of empirical evidence to support its effectiveness. In addition, Multisensory Structured Language Instruction includes the foundational skills recommended by the National Reading Panel (2000), but the use of multiple senses to teach these skills has not been thoroughly studied. This theoretical dissertation focused on one element …

Walking In Two Worlds: Living An Animistic Spiritual Worldview In The Western United States, Joanne Dorpat Halverson

Antioch University Dissertations & Theses

An abundance of culturally derived ideological influences inform our lives. The dominant culture exerts a powerful influence on understandings of reality. For some people, their spiritual way of being in the world deviates from cultural norms. In this qualitative study I sought to understand the lived experience of people who hold an animistic spiritual worldview and yet function well within society. They walk in two worlds. The research design employed both phenomenological and heuristic methods. To understand the socio-cultural-historical context of the study a lengthy background was provided. Six individuals who self-identified as adhering to animistic spirituality living on the …

Restoring Relationships: Indigenous Ways Of Knowing Meet Undergraduate Environmental Studies And Science, Nancy Leigh Rich

Antioch University Dissertations & Theses

As places to engage with changing and complex ideas, institutions of higher education offer a logical site for bringing Indigenous ways of knowing together with environmental studies and science. However, profound differences between Indigenous and Western knowledges, as well as ongoing colonialism, cultural biases of science, and the nature of mainstream academia, have discouraged this endeavor. Recent developments in undergraduate pedagogy now point the way.

Using critical inquiry and qualitative methodology, this comparative study developed recommendations for practice based on current undergraduate teaching practices that bring Indigenous ways of knowing together with environmental studies and science across a diversity of …

Dormant Ethnobotany: A Case Study Of Decline In Regional Plant Knowledge In The Bull Run Mountains Of Virginia, Susan Rene Leopold

Antioch University Dissertations & Theses

This dissertation introduces and applies the concept of dormant ethnobotany, a concept that helps explain the socio-economic, cultural and ecological aspects and implications of the transition away from active use of ethnobotanical knowledge and the factors that may lead to its re-emergence. Dormant ethnobotany is the study of relationships between people and plants that are inactive, but nonetheless still alive in memories, the historic record, and folklore and thereby capable of reemergence in support of the transition to a more sustainable society. The dissertation extends the field of ethnobotany from its current roots in the dynamic ethnobotany of indigenous peoples. …

A Conceptualization Of Treatment Stigma In Returning Veterans, Jason B. Flick

Antioch University Dissertations & Theses

The dissertation project combines three theoretical models that inform conceptualizations of the origins, manifestations, and consequences of stigma: the Social Psychological model (SPM), the Sociological model (SM), and the Cognitive-behavioral model (CBM). These models merge into a single, integrative lens, through which stigma can be examined on both cultural and individual levels. This lens is then applied to the cultural and individual manifestations of the stigma of seeking psychological treatment experienced by veterans who have served in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). Through this lens, an understanding of the inception, maintenance, and effects of this treatment …

A Self-Psychological Exploration Of Multiple Sclerosis In Its Biopsychosocial Context, Elisabeth Anne Parrott

Antioch University Dissertations & Theses

This theoretical dissertation constructs a new frame of reference for understanding relapsing-remitting multiple sclerosis (RRMS) using self psychology to develop a biopsychosocial formulation of the illness in order to better inform the medical treatment of patients. After conducting a critical exploration of MS in its historical context and providing a brief overview of the etiology of MS, this paper examines the phenomenology of the illness using the concepts of self psychology to further develop the theory of Engel’s (1977) biopsychosocial model. The relationship among biological, intrapsychic, and social factors and coherent conceptualization and medical treatment of multiple sclerosis is addressed. …

Family Structure As A Social Context For Family Conflict: Unjust Strain And Serious Delinquency, Ryan Spohn, Don L. Kurtz

Center on Children, Families, and the Law: Faculty Publications

Two major themes in the delinquency literature are the roles of family structure and childhood victimization. Combining these two lines of research, the current project examines the unique contribution of family structure and victimization on the serious delinquency of a nationally representative sample of adolescents. In addition, we examine whether the form of families serves to condition the relationship between victimization and delinquency. Past research indicates that abuse is more likely to occur in two-parent families of a ‘‘mixed’’ form, specifically in the presence of a live-in boyfriend or stepfather. However, little is known regarding the impact of victimization on …

A Graph-Based Algorithm To Determine Protein Structure From Cryo-Em Data, Stephen Schuh

All Theses and Dissertations (ETDs)

Cryo-electron microscopy: cryo-EM) provides 3D density maps of proteins, but these maps do not have sufficiently high resolution to directly yield atomic-scale models. Previous work has shown that features known as secondary structures can be located in these density maps. A second source of information about proteins is sequence analysis, which predicts locations of secondary structures along the protein sequence but does not provide any information about the 3D shape of the protein. This thesis presents a graph-based algorithm to find the correspondence between the secondary structures in the density map and sequence. This provides an ordering of secondary structures …

Quantitative Assessment Of Lung Microstructure In Healthy Mice Using An Mr-Based 3he Lung Morphometry Technique, Emir Osmanagic

All Theses and Dissertations (ETDs)

Recently developed in our laboratory the MRI-based technique - 3He Lung Morphometry - is a unique tool allowing in vivo measurements of lung microstructural parameters such as alveolar volume, surface-to-volume ratio and alveolar density. These parameters are commonly used by lung physiologists and pathologists but were previously available only from invasive biopsy studies. 3He Lung Morphometry was originally developed for human studies but there is a need to expand it for studies of small animals like mice and rats that are used to advance our knowledge of lung physiology in health and disease and for development of drugs. Such an …

Mechanics Of Heart Tube Formation In The Early Chick Embryo, Victor Varner

All Theses and Dissertations (ETDs)

The heart is the first functioning organ to form in the embryo. For decades, biologists have worked to identify many of the genetic and molecular factors involved in heart development, and over the years, these efforts have helped elucidate the vast biochemical signaling networks, which drive cardiac specification and differentiation in the embryo. Still, the biophysical mechanisms which link these molecular factors to actual, physical changes in cardiac morphology remain unclear. The aim of this thesis is to identify some of the mechanical forces which drive heart tube assembly in the early chick embryo. A unique feature of this work …

Computational Methods For Accelerated Discovery And Characterization Of Genes In Emerging Model Organisms, Alan Kwan

All Theses and Dissertations (ETDs)

Cilia are evolutionarily conserved, complex, microtubule-based structures that protrude from many eukaryotic cells. In humans, cilia can be found on almost all cell types. The effect of abnormal or absent cilia has been established as the common underlying cause of a recently emerging class of genetic diseases collectively referred to as ciliopathies. The function and structure of cilia are conserved across all organisms with cilia. One of the most influential model systems used to study ciliopathies has been the ciliated green alga Chlamydomonas reinhardtii, an organism for which there is a sequenced genome with relatively few experimentally validated whole-gene annotations …

Low-Impact Profiling Of Streaming, Heterogeneous Applications, Joseph Lancaster

All Theses and Dissertations (ETDs)

Computer engineers are continually faced with the task of translating improvements in fabrication process technology: i.e., Moore's Law) into architectures that allow computer scientists to accelerate application performance. As feature-size continues to shrink, architects of commodity processors are designing increasingly more cores on a chip. While additional cores can operate independently with some tasks: e.g. the OS and user tasks), many applications see little to no improvement from adding more processor cores alone. For many applications, heterogeneous systems offer a path toward higher performance. Significant performance and power gains have been realized by combining specialized processors: e.g., Field-Programmable Gate Arrays, …

Optimization Of Gene Prediction Via More Accurate Phylogenetic Substitution Models, Ezekiel Maier, Randall H. Brown, Michael R. Brent

All Computer Science and Engineering Research

Determining the beginning and end positions of each exon in each protein coding gene within a genome can be difficult because the DNA patterns that signal a gene’s presence have multiple weakly related alternate forms and the DNA fragments that comprise a gene are generally small in comparison to the size of the genome. In response to this challenge, automated gene predictors were created to generate putative gene structures. N SCAN identifies gene structures in a target DNA sequence and can use conservation patterns learned from alignments between a target and one or more informant DNA sequences. N SCAN uses …

Can Havruta Style Learning Be A Best Practice In Law School?, Barbara P. Blumenfeld

Faculty Scholarship

Havruta is a traditional Jewish method that seems compatible with legal education because of its focus on process, and so adaptable to law school training in legal reasoning, and because it is based upon dispute and resolution, another aspect that corresponds with the study of law. A unique form of collaborative student centered learning involving pairs of students, this article considers the application of Havruta to the law school setting and whether it should be incorporated into the law school curriculum.

You Can Lead Them To Water, But You Can’T Make Them Drink: Using Crowd Sourcing To Lead Library Patrons To Extended Library Services Relevant To Their Search Criteria, William B. Lund, Chad Hansen

Faculty Publications

The Lee Library at Brigham Young University has extensive resources in the forms of highly skilled subject librarians, print resources and digital collections, but getting the students to be aware of and use them effectively is a problem. To help inform library patrons of these resources librarian subject specialists have created over 150 subject guides using LibGuides for subject areas, classes, and some subspecialties, which was an enormous task; but are these resources being used effectively? This paper explores and reports on a subject guide recommender system, which recommends relevant subject guides based on patron searches, using a crowd sourced …

Leverage: Review Of Burk & Lemley, 'The Patent Crisis And How The Courts Can Solve It', Stephen M. Mcjohn

Suffolk University Law School Faculty Works

Dan L. Burk and Mark A. Lemley’s “The Patent Crisis and How the Courts Can Solve It” (The University of Chicago Press, 2009) is valuable for anyone interested in patent law. The book serves two goals. First, it suggests how patent reform in the United States can best be accomplished: not through Congressional amendment of the patent statute, but by judicial implementation of industry-specific reforms, in interpreting the existing act. Some jurisdictions, such as India, already differentiate between industrial sectors more explicitly in patent policy than the United States. Second, of interest to patent law worldwide, the book provides a …

Alterations In Ion Levels Of Freshwater Fish Oreochromis Niloticus Following Acute And Chronic Exposures To Five Heavy Metals, Gülüzar Atli, Mustafa Canli

Turkish Journal of Zoology

Freshwater fish, Oreochromis niloticus, were individually exposed to 0, 0.1, 0.5, 1.0, and 1.5 µg/mL of Cu^{2+}, Cd^{2+}, Cr^{6+}, Ag^+, and Zn^{2+} for 96 h (acute) and 0.05 µg/mL concentrations of the same metals for 0, 5, 10, 20, and 30 days (chronic). Following each period, metal accumulation and ion levels (Na^+, K^+, Ca^{+2}, and Mg^{+2}) were measured in the gills, kidneys, and muscles. Except for Ag^+, none of the metals killed the fish within 30 days. Silver killed all the fish within 16 days. With the exceptions of Ag^+ and Cr^{6+}, as their levels were below detection limits, metal …
