Optimal Data Partitioning And A Test Case For Ray-Finned Fishes (Actinopterygii) Based On Ten Nuclear Loci, Chenhong Li, Guoqing Lu, Guillermo Orti

Biology Faculty Publications

Data partitioning, the combined phylogenetic analysis of homogeneous blocks of data, is a common strategy used to accommodate heterogeneities in complex multilocus data sets. Variation in evolutionary rates and substitution patterns among sites are typically addressed by partitioning data by gene, codon position, or both. Excessive partitioning of the data, however, could lead to overparameterization; therefore, it seems critical to define the minimum numbers of partitions necessary to improve the overall fit of the model. We propose a new method, based on cluster analysis, to find an optimal partitioning strategy for multilocus protein-coding data sets. A heuristic exploration of alternative …

Variation Of The Synarcual In The California Ray, Raja Inornata (Elasmobranchii: Rajidae), Kerin M. Claeson

PCOM Scholarly Works

Seven juvenile specimens of Raja inornata were CT scanned and digitally modeled to examine the variation of synarcual morphology with changing size. The synarcual is a highly variable skeletal element across batoids with great potential for use in phylogenetic studies. Results show that as R. inornata increases in body size, the synarcual becomes more elongate and laterally compressed. Projections of the synarcual become more pronounced with increasing size as well. The synarcual of R. inornata is narrower than that of R. erinacea. There appears to be a correlation between median crest width and synarcual spine size. Also, in the context …

Dispersal Ability And Parasitization Performance Of Egg Parasitoid Trichogramma Evanescens Westwood (Hymenoptera: Trichogrammatidae) In Field And Storage Conditions, Abdurrahman Ayvaz, Eyüp Karasu, Sali̇h Karabörklü, Semi̇h Yilmaz

Turkish Journal of Biology

In this study we evaluated the dispersal ability of Trichogramma evanescens in field and storage conditions. In field studies we tested the effects of plant structure on the dispersal ability of T. evanescens from release points. Both in a corn field and on grapevines the level of parasitism was negatively correlated with distance when the host eggs were located away from the release point. The parasitization rate on grapevines and corn plants at the release point was greater than that away from the release point. Parasitization rates were significantly higher at the highest wasp density in cages. When 1000 wasps …

Gamma Ray- And Ems-Induced Bold-Seeded High-Yielding Mutants In Chickpea (Cicer Arietinum L.), Aijaz A. Wani, Mohammad Anis

Turkish Journal of Biology

Three bold-seeded high-yielding mutants were isolated from the M_2 progeny of chickpea var. Pusa-212, viz. Pusa-212 A (200 Gy), Pusa-212 C (400 Gy), and Pusa-212 F (300 Gy + 0.2% EMS). Data on various quantitative traits, such as plant height, number of branches per plant, number of pods per plant, number of seeds per pod, 100-seed weight (g), seed yield (g) per plant, and protein content (%), were recorded for all 3 mutants in the M3 generation. The mutants were morphologically quite distinct, as compared to the control and to each other. The most notable change was in seed size …

Desert Rocks – A Habitat Which Supports Many Species That Were New To Science In The Last 40 Years, Avinoam Danin

Turkish Journal of Botany

Hard limestone, dolomite, sandstone, and granite constitute, under certain conditions, smooth-faced outcrops in desert areas of SW Asia. This habitat supports the most rare plant species in the desert including most of the desert endemics of Israel, Sinai, and Jordan. The smooth-faced outcrops efficiently contribute runoff water to the rock crevices and events when water is available for plant utilisation take place at a higher frequency than in the other habitats in the desert. In many sites plants are isolated and protected by impermeable rocks from competition from other plants. The rare and special plants found in this habitat include …

Soaproot Yielding Plants Of East Anatolia And Their Potential In Nature, Mehmet Koyuncu, Ceyda Si̇bel Kiliç, Ayşegül Güvenç

Turkish Journal of Botany

Soaproot (Radix Gypsophilae) is an important herbal drug having medicinal and economic importance and has been collected from nature for more than 30 years. The main goal of this study was to determine soaproot yielding plant species in East Anatolia, and their potential in nature. Collected plants were determined by field studies; damage to the environment after collection was observed, and commerce, exportation, domestic utilisation of soaproot, and problems and proposed solutions were examined. Soaproot is presently obtained from a total of 7 plant species belonging to 2 genera in Turkey (6 Gypsophila L., 1 Ankyropetalum Fenzl): G. graminifolia Bark, …

Inhibition Of Oncogene-Induced Inflammatory Chemokines Using A Farnesyltransferase Inhibitor., Katharine C Degeorge, Brent R Degeorge, James S Testa, Jay L Rothstein

Department of Microbiology and Immunology Faculty Papers

ABSTRACT: BACKGROUND: Farnesyltransferase inhibitors (FTI) are small molecule agents originally formulated to inhibit the oncogenic functions of Ras. Although subsequent analysis of FTI activity revealed wider effects on other pathways, the drug has been demonstrated to reduce Ras signaling by direct measurements. The purpose of the current study was to determine if FTI could be used to inhibit the inflammatory activities of a known Ras-activating human oncoprotein, RET/PTC3. RET/PTC3 is a fusion oncoprotein expressed in the thyroid epithelium of patients afflicted with thyroid autoimmune disease and/or differentiated thyroid carcinoma. Previous studies have demonstrated that RET/PTC3 signals through Ras and can …

A Comprehensive Analysis Of The Naturally Occurring Polymorphisms In Hiv-1 Vpr: Potential Impact On Ctl Epitopes., Alagarsamy Srinivasan, Velpandi Ayyavoo, Sundarasamy Mahalingam, Aarthi Kannan, Anne Boyd, Debduti Datta, Vaniambadi S Kalyanaraman, Anthony Cristillo, Ronald G Collman, Nelly Morellet, Bassel E Sawaya, Ramachandran Murali

Department of Microbiology and Immunology Faculty Papers

The enormous genetic variability reported in HIV-1 has posed problems in the treatment of infected individuals. This is evident in the form of HIV-1 resistant to antiviral agents, neutralizing antibodies and cytotoxic T lymphocytes (CTLs) involving multiple viral gene products. Based on this, it has been suggested that a comprehensive analysis of the polymorphisms in HIV proteins is of value for understanding the virus transmission and pathogenesis as well as for the efforts towards developing anti-viral therapeutics and vaccines. This study, for the first time, describes an in-depth analysis of genetic variation in Vpr using information from global HIV-1 isolates …

Using Ninhydrin To Detect Gravesoil, David O. Carter, David Yellowlees, Mark Tibbett

Department of Entomology: Faculty Publications

Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might have potential as a tool for the identification of clandestine graves. Juvenile rat (Rattus rattus) cadavers were buried in three contrasting soil types in Australian tropical savanna ecosystems and allowed to decompose over a period …

Sugar Feeding In Adult Stable Flies, David B. Taylor, Dennis R. Berkebile

Department of Entomology: Faculty Publications

Adult stable flies (Stomoxys calcitrans L.) are known to feed readily on sugars in the laboratory. However, little is known concerning the extent of stable fly sugar feeding in wild populations. We examined the frequency of sugar feeding in stable flies collected on Alsynite sticky traps in rural and urban environments. In addition, stable flies were visually examined to determine whether blood was present in the gut. In laboratory studies, sugars were detectable with the anthrone technique in stable flies for ~3 d after being imbibed, and blood could be visually detected in the gut for 24-48 h after …

Preparing Students For Democratic Participation: Why Teacher Curricular Speech Should Sometimes Be Protected By The First Amendment, Anne Gardner

Missouri Law Review

This note will examine the legal basis and educational framework for First Amendment protection of classroom speech. The Supreme Court of the United States has not directly addressed the constitutional issues implicated in teacher classroom speech. As a result, the circuit courts are split in the application of an appropriate analysis.15 In most circuits, teacher curricular speech is not protected speech.' 6 Among the circuit courts, teacher curricular speech is governed by three competing doctrines: public employee speech, student speech, and academic freedom. 1 7 While the Fourth, Fifth, Sixth, and Seventh Circuits have applied the Pickering public employee analysis,' …

Classroom-Based Empathy Training: An Evaluation Of Program Effects In An Elementary School, Kimberly Sherman

Open Access Dissertations

Universal classroom-based social skills and violence prevention training is currently a topic of widespread interest. Although there is a growing body of empirical support for some existing social skills programs, less is known about contributions of specific program components to intervention outcomes. Empathy training is one common component of social skills curricula that has been subject to relatively little research. The current study is a single-school quasi-experimental investigation of Second Step empathy training effects on 57 first- and fourth-graders. Dependent variables included self-reported empathy, teacher-reported social skills, teacher-reported problem behaviors, and fourth-graders' self-reported social skills. The study also explored teachers' …

Evidence For Low Levels Of Genetic Variation Among Zostera Marina Populations From The Atlantic West Coast, Eric Rosenzweig

Theses, Dissertations and Culminating Projects

Zoster a marina (eelgrass), can be found in the North Atlantic on the coast of Europe and the North Arctic, as well as the Pacific. On the Atlantic west coast this species grows as far south as North Carolina and into northern Canada. The cold waters of these regions support the habitat needed for the species. Eelgrass is vital to coastal communities. It serves as a food source for many organisms, hatching ground for fish species, absorbent of water pollutants, and soil stabilizer. Over the last 30 years, the once robust populations of Atlantic west coast eelgrass have withered into …

Hands-On Materials For Teaching About Global Climate Change Through Graph Interpretation, Audrey C. Rule, J. E. Hallagan, B. Shaffer

Open Educational Resources

Teachers need to address global climate change with students in their classrooms as evidence for consequences from these environmental changes mounts. One way to approach global climate change is through examination of authentic data. Mathematics and science may be integrated by interpreting graphs from the professional literature. This study examined the types of errors 72 preservice elementary teachers made in producing hands-on materials for teaching graph interpretation skills through graphed evidence of global climate change from the literature. The teaching materials consisted of a graph electronically manipulated on a colored background and enhanced with clip art related to the graph’s …

Density Of Gutta Percha By Weight In Straight Root Canals And Curved Root Canals After Single Cone, Cold Lateral, And Warm Vertical Condensation, Gerald Clay Sparrow

Theses and Dissertations

The purpose of this study was to compare the density of gutta percha following three different obturation techniques using two split-tooth models. One split-tooth model was constructed with a straight rooted maxillary incisor and the other with the curved palatal root of a maxillary molar. Each tooth was obturated using single cone, cold lateral, and warm vertical obturation techniques without sealer. Each obturation technique was performed 20 times for each of the root systems. The weights of the gutta percha were recorded for each root type and obturation technique by subtracting the post-fill weight from the pre-fill weight of the …

Happy Law Students, Happy Lawyers, Nancy Levit, Douglas O. Linder

Faculty Works

This article draws on research into the science of happiness and asks a series of interrelated questions: Whether law schools can make law students happier? Whether making happier law students will translate into making them happier lawyers, and the accompanying question of whether making law students happier would create better lawyers? After covering the limitations of genetic determinants of happiness and happiness set-points, the article addresses those qualities that happiness research indicates are paramount in creating satisfaction: control, connections, creative challenge (or flow), and comparisons (preferably downward). Those qualities are then applied to legal education, while addressing the larger philosophical …
