Eukaryotic Translation Initiation Factor 5b Activity Regulates Larval Growth Rate And Germline Development In Caenorhabditis Elegans, Xiang Yu, Valarie E. Vought, Barbara Conradt, Eleanor M. Maine

Biology - All Scholarship

In C. elegans, a population of proliferating germ cells is maintained via GLP-1/Notch signaling; in the absence of GLP-1 signaling, germ cells prematurely enter meiosis and differentiate. We previously identified ego (enhancer of glp-1) genes that promote germline proliferation and interact genetically with the GLP-1 signaling pathway. Here, we report that iffb-1 (initiation factor five B) is an ego gene. iffb-1 encodes the sole C. elegans isoform of eukaryotic translation initiation factor 5B, a protein essential for translation. We have used RNA interference and a deletion mutation to determine the developmental consequences of reduced iffb-1 activity. Our data indicate that …

Arbuscular Mycorrhizae Effects On Growth Of Two Hawaiian Species: Indigenous Osteomeles Anthyllidifolia (Rosaceae) And Invasive Psidium Cattleianum (Myrtaceae), R. E. Koske, J. N. Gemma

Biological Sciences Faculty Publications

Two important plant species of Hawai'i, the indigenous Osteomeles anthyllidifolia (Sm.) Lindl., a component of Hawai'i's most endangered habitat, and the highly invasive Psidium cattleianum Sabine were grown with or without arbuscular mycorrhizal fungi in a soilless mix at different soil-solution phosphorus (P) levels. At P levels similar to those in the field (0.007 mg P/liter), shoot biomass of inoculated plants of O. anthyllidifolia was 189% greater than that of controls, and that of P. cattleianum was 93% greater. Root weight of O. anthyllidifolia and leaf-tissue P of both species also were significantly higher in inoculated plants. At a higher …

The Effect Of Process Oriented Guided Inquiry Learning On Student Achievement In A One Semester General, Organic, And Biochemistry Course., Lafayette Eaton

Mathematical and Computing Sciences Masters

The effects of process oriented guided inquiry learning (POGIL), a student centered cooperative learning strategy, on achievement in an introductory college chemistry course was examined. Students in the treatment groups (n = 39 & n = 47) who experienced the student centered cooperative learning will be compared to students in the control group (n = 33) who experienced traditional lecture. The differences between exam scores in the control group and those in each treatment group will be evaluate using a one way analysis of variance. The results indicate that students in both treatment groups performed below those in control group …

Bridging The Digital Divide In Public Participation: The Roles Ofinfrastructure, Hardware, Software And Social Networks In Helsinki’S Arabianranta Andmaunula, C. J. Gabbe

Environmental Studies and Sciences

Information and communications technology (ICT) itself does not provide communities with a more effective voice in the planning process. However, when ICT is used as a tool to build stronger neighborhood social networks, it can catalyze public participation in planning. The use of ICT as a community-building tool requires a combination of network infrastructure, hardware and software, according to the literature. Additionally, it requires the utilization of human social networks. Based on my study of Helsinki’s Arabianranta and Maunula neighborhoods, I found that catalyzing collaborative planning in Helsinki using ICT requires a combination of infrastructure, hardware, software, and, most importantly, …

Rounding Up Students' Conceptions On Circular Motion, Shannon Mclaughlin

Iowa Science Teachers Journal

The purpose of this paper is to provide insight on how introducing circular motion with a carefully designed sequence of demonstrations and activities consistent with the national standards, pedagogical knowledge, and research-based instructional practices can flush out students' conceptions of forces and motion, and set a conceptual foundation for understanding uniform circular motion. This article promotes National Science Education Content Standards A, B, and E, and Iowa Teaching Standards 1, 2, 3, and 4.

Colorblindness: Invisible Disability, John Stiles

Iowa Science Teachers Journal

In nearly every classroom sits at least one student who is unable to distinguish between certain colors. This incurable, genetic, and sex-linked condition is particularly frustrating in science class, a subject in which color discrimination is frequently required. Teachers are often unaware of this invisible disability, which many "colorblind" students try to keep secret in order to avoid embarrassment. There are a number of modifications a science teacher can make to reduce, or in some instances remove, barriers to learning for colorblind students. In addition, a simple, free test may help identify young children who have color difficulties, so they …

Identification Of A Novel Inhibitory Actin-Capping Protein Binding Motif In Cd2-Associated Protein, Serawit Bruck, Tobias B. Huber, Robert J. Ingham, Kyoungtae Kim, Hanspeter Niederstrasser, Paul M. Allen, Tony Pawson, John A. Cooper, Andrey S. Shaw

College of Natural and Applied Sciences

CD2-associated protein (CD2AP) is a scaffold molecule that plays a critical role in the maintenance of the kidney filtration barrier. Little, however, is understood about its mechanism of function. We used mass spectrometry to identify CD2AP-interacting proteins. Many of the proteins that we identified suggest a role for CD2AP in endocytosis and actin regulation. To address the role of CD2AP in regulation of the actin cytoskeleton, we focused on characterizing the interaction of CD2AP with actin-capping protein CP. We identified a novel binding motif LXHXTXXRPK(X)6P present in CD2AP that is also found in its homolog Cin85 and other capping protein-associated …

Biomems Wireless Pressure Sensor, Daniel V. Pearce

Journal of the Microelectronic Engineering Conference

A design and manufacture of a wireless pressure sensor was proposed as a future tool for use in biological monitoring. This device is designed to acquire pressure changes through a change in capacitance. This is accomplished using a large circular parallel plate capacitor separated by a micron of air. The upper and lower plates are connected together via a large planar inductor on the opposite end of the device. The inductor and capacitor in a parallel form a resonant circuit with resonant frequency equal to one over the square root of inductance times capacitance. The resonant frequency can be dependent …

Boosting Science Learning Through The Design Of Curriculum Materials, Rodger Bybee

2006 - Boosting Science Learning - What will it take?

How can curricula enhance science teaching and student learning? A slightly deeper and more specific question than that is: what is the form and function of effective curriculum materials? These questions will be addressed in the following discussion. After a brief introduction to BSCS (Biological Sciences Curriculum Study), I will first discuss what we know about how students learn science and introduce an instructional model based on this research from the cognitive sciences. I will then review the curriculum development process at BSCS and describe a contemporary high school program and evidence of student learning attributed to that program.

Creating Powerful Teacher Education Opportunities: The Need For Risk, Relevance, Resource, Recognition, Readiness And Reflection, Susan Rodrigues

2006 - Boosting Science Learning - What will it take?

Two projects described in this paper illustrate what a successful teacher education model can look like, what its aims were, what happened in terms of teacher professional development, and what pupils accomplished as a result. The paper also describes policies, organisational features, resources, and relationships that informed the projects. In effect, both projects involved a community of teachers, educators and scientists working to develop resource materials involving various technologies for classroom use. Data was collected through teacher surveys, online dialogue, interviews, pupil work, teacher ‘show and tell’ and limited classroom observation. The data suggests that pedagogic change warrants the presence …

Science Achievement In Australia : Evidence From National And International Surveys., Sue Thomson

2006 - Boosting Science Learning - What will it take?

What can be said about science achievement in Australian schools? Does it really need a boost? Is science education in Australia engaging and motivating, or is the curriculum irrelevant and students disinterested? Are there particular issues for Indigenous students? Within the National Testing Program, Australia participates in two major international studies with a partial focus on science: the Trends in International Mathematics and Science Study (TIMSS), conducted with Year 4 and Year 8 students conducted with 15-year-old students. In addition, the Longitudinal Surveys of Australian Youth (LSAY) program provides evidence about the outcomes of education, and the TIMSS Science Video …

What Science Do Students Want To Learn? What Do Students Know About Science?, Barry Mcrae

2006 - Boosting Science Learning - What will it take?

In 2006, for the first time, science is the major focus of the PISA assessment of 15-year-olds. A major innovation in PISA 2006 is that many of the science units contain one or two items designed to assess students' attitudes towards science – in particular, their interest in learning about science and their support for scientific enquiry. A second major innovation is that some of the items assess students' knowledge about science – that is, their knowledge of scientific methodology. This paper presents some field trial results that shed light on what science students want to learn, and how their …

The Confluence Of Intersubjectivity And Dialogue In Postmodern Organizational Workgroups, Daniel J. Shuster

College of Business and Technology - Graduate Student Scholarship

Nascent revival of dialogue is struggling to reach its potential within the postmodern organizational milieu. Concurrently, interpersonal intersubjectivity has steadily been de-pathologized, via reassessments of countertransference in the psychoanalytic sphere, allowing exploration of its utility in other domains of relational process. Effective use of dialogue is critical and foundational to developing meaningful and sustainable enterprise in the immediate future. Despite the risks, intentionally explored intersubjectivity is a powerful tool to enrich the container of dialogue. This paper qualitatively explores the literature on intersubjectivity and dialogue with an hermeneutic approach to discern the implications of their convergence for collaborative workgroups in …

Exploring Important Protein Interactions In The Mammalian Diaphanous-Related Formins: A Closer Look At The Relationship Between The Intracellular Skeletal Network And A Single Amino Acid Residue, Brent Hehl

McNair Scholars Journal

The Diaphanous-related formin protein family plays a key role in intracellular cytoskeletal regulation. Due to their farreaching importance, these proteins must be highly regulated themselves. With recent exploration of regulatory processes of mDia2, a formin protein found in mammals, the established mechanism of control appears to be more complex than previously thought. This project examines the possibility of phosphorylation at critical sites near the protein regions that regulate formin function. Here, we outline our initial screen for discovering these specific residues within mDia2 and their potential for phosphorylation using site-directed mutagenesis.

Study Of The Human Mitochondrial Dna Polymorphism, Catherine Willis

McNair Scholars Journal

Traces of Paleolithic exodus routes of modern humans from Africa to Europe have been studied genetically using female specific ancestral lineages via mitochondrial DNA (mtDNA). We suggest modern humans entered Europe near the Carpathian Mountains and Hungarian Valley. If so, isolated populations of highlanders in Carpathian Europe may carry a genetic fingerprint of the ancient European predecessors and illustrate the migration routes of modern humans into Europe. Lineage-specific polymorphic sites on mtDNA were analyzed in the Carpathian Highlander population. The Carpathian Highlanders genetically resemble modern Europeans when analyzed by a hierarchical haplotyping scheme; however more studies need to be undertaken …

Benthic Nutrient Flux In A Small Estuary In Northwestern Florida (Usa), Guy T. Didonato, Emile M. Lores, Michael C. Murrell, Lisa M. Smith, Jane M. Caffrey

Gulf and Caribbean Research

Benthic nutrient fluxes of ammonium (NH₄⁺), nitrite/nitrate (NO₂^- + NO₃^-), phosphate (PO₄^-3), and dissolved silica (DSi) were measured in Escambia Bay, an estuary within the larger Pensacola Bay system of northwestern Florida (USA). Our study occurred during a severe drought which reduced riverine inputs to Escambia Bay. Laboratory incubations of field-collected cores were conducted on 8 dates between June and October 2000 to estimate nutrient flux, and cores were collected from locations exhibiting a range of sediment organic matter content. NH₄⁺ flux ranged from – 48.1 to …

Feeding Habits Of Common Snook, Centropomus Undecimalis, In Charlotte Harbor, Florida, David A. Blewett, Rebecca A. Hensley, Philip W. Stevens

Gulf and Caribbean Research

We examined the feeding habits, ontogenetic and seasonal diet variations, and predator size–prey size relationships of common snook, Centropomus undecimalis, in Charlotte Harbor, Florida, through stomach contents analysis. A total of 694 stomachs were extracted from common snook (300–882 mm standard length [SL]) during a 24-month period (March 2000–February 2002); 432 stomachs contained prey items. At least 37 prey taxa were identified, including 19 that had not been previously reported. Fishes made up 71% of the prey by number and 90% by weight. Three prey items made up almost 50% of the diet numerically—Lagodon rhomboides, Anchoa spp., …
