Imagine Math Day: Encouraging Secondary School Students And Teachers To Engage In Authentic Mathematical Discovery, Darryl H. Yong, Michael E. Orrison Jr.

All HMC Faculty Publications and Research

Research mathematicians and school children experience mathematics in profoundly different ways. Ask a group of mathematicians what it means to “do mathematics” and you are likely to get a myriad of responses: mathematics involves analyzing and organizing patterns and relationships, reasoning and drawing conclusions about the world, or creating languages and tools to describe and solve important problems. Students of mathematics often report “doing mathematics” as performing calculations or following rules. It’s natural that they see mathematics as monolithic rather than an evolving, growing, socially constructed body of knowledge, because most mathematical training in primary and secondary schools consists of …

Phytopathogen Type Iii Effector Weaponry And Their Plant Targets, Anna Block, Guangyong Li, Zheng Qing Fu, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

Phytopathogenic bacteria suppress plant innate immunity and promote pathogenesis by injecting proteins called type III effectors into plant cells using a type III protein secretion system. These type III effectors use at least three major strategies to alter host responses. One strategy is to alter host protein turnover, either by direct cleavage or by modulating ubiquitination and targeting to the 26S proteasome. Another strategy involves alteration of RNA metabolism by transcriptional activation or ADP-ribosylation of RNA-binding proteins. A third major strategy is to inhibit the kinases involved in plant defence signalling, either by removing phosphates or by direct inhibition. The …

Family Richness And Diversity Of Vascular Epiphytes And Climbers In The Canopy Of A Lower Montane Wet Forest, Costa Rica, August 2008, Jennifer D. Savidge

Monteverde Institute: Tropical Ecology and Conservation

Many studies have been done regarding vascular epiphyte communities in the tropics, however all of the previous studies have neglected the canopy branch tips due to their limited accessibility (Nieder et al. 2004, Freiberg and Freiberg 2000, Zotz et al. 1999, Hietz 1997, Freiberg 1996, Ingram and Nadkarni 1993). The purpose of this study was to evaluate differences in family richness, and diversity of previously unstudied branch tip epiphyte communities vs. those of secondary branch bases. Data were gathered about community composition of vascular epiphyte families and climbers on the branch tips of canopy trees in a Neotropical, lower montane …

The Influence Of Cultural Identification And Gender-Linked Characteristics On The Body Satisfaction Of African American Men, Amy Lynn Baird

Masters Theses & Specialist Projects

The goal of the present study was to examine the relationships between gender schema, level of cultural identification, and body dissatisfaction in African American men. The first hypothesis under study was that men with a low identification to African American culture would report higher dissatisfaction with their body than those with a high cultural identification. Secondly, it was hypothesized that men with a large discrepancy from their culture’s description of an “ideal man” would also report higher body dissatisfaction than those with low or no discrepancy. Lastly, it was hypothesized that an interaction between variables would occur and that men …

Family Communication Patterns: Can They Impact Leadership Styles?, Suthida Prasitthipab

Masters Theses & Specialist Projects

A plethora of studies has worked on family communication and leadership separately. Little research has combined these two components although they both relate to personality characteristics and communication styles. Therefore, this thesis investigated correlations between leadership styles and family communication patterns during childhood. Two hypotheses were proposed representing the relationship between conformity orientation and task leadership, and between conversation orientation and relation leadership.

Faculty, non-academic staff, and students in leadership positions from Western Kentucky University were samples of this study. They completed a questionnaire voluntarily. Family communication pattern scale and Leadership Behavior Descriptive Questionnaire were used in the survey. Pearson …

Agreement And Group Attraction In Face-To-Face And Computer-Mediated Group Discussions, Krishnamurti Murniadi

Masters Theses & Specialist Projects

Topics within small-group communication have been explored in many contexts, such as work group, organizational meeting, or online network. This area of discipline is considered crucial because this type of communication assimilates interpersonal relations within a social setting. Two elements that largely affect small-group communication dynamics are anonymity and social identity. This research invokes previous research in anonymity and social identity within small-group communication pertaining to the level of agreement and the level of group attraction through a series of experiments.

Anonymity in small-group communication context is defined as a condition where the group members are not identifiable. To create …

Conversion Of Traditional Observation-Based Botany Labs To Investigative Inquiry Learning, Hajara Mahmood

Masters Theses & Specialist Projects

“Tell me and I forget, show me and I remember, involve me and I understand.” - Chinese Proverb. Involvement in learning implies possessing skills and attitudes that permit students to seek resolutions to questions and issues while constructing new knowledge.

Low enrollment in Plant Biology and Diversity and upper level plant science courses has been noticed at Western Kentucky University. In addition, graduating students performed below the national average on the senior assessment examination in the area of botany content knowledge offered by WKU’s Biology Department. This may be due to the fact that observation-based botany has been taught in …

Population Structure Of Limenitis Butterflies In Hickman, Kentucky, Mollie Johnson

Masters Theses & Specialist Projects

Two species of Limenitis butterflies occur along the Mississippi River at Hickman, Kentucky: the viceroy, L. archippus, and the red-spotted purple, L. arthemis astyanax. Limenitis archippus occurs at a frequency that is 10-30 times more abundant than its congener, L. arthemis astyanax. Interspecific matings between L. archippus and L. arthemis astyanax are very rare in the wild and give rise to a hybrid form Limenitis archippus X L. arthemis astyanax form rubidus. Only 7 heterospecific pairings between the parental species and 72 "rubidus" individuals have been documented in the wild in all of North America. Of these documented cases, 2 …

I. Vh Gene Transcription Creates Stabilized Secondary Structures For Coordinated Mutagenesis During Somatic Hypermutation, Barbara E. Wright, Karen H. Schmidt, Michael F. Minnick, Nick Davis

Biological Sciences Faculty Publications

During the adaptive immune response, antigen challenge triggers a million-fold increase in mutation rates in the variable-region antibody genes. The frequency of mutation is causally and directly linked to transcription, which provides ssDNA and drives supercoiling that stabilizes secondary structures containing unpaired, intrinsically mutable bases. Simulation analysis of transcription in VH5 reveals a dominant 65nt secondary structure in the non-transcribed strand containing six sites of mutable ssDNA that have also been identified independently in human B cell lines and in primary mouse B cells. This dominant structure inter-converts briefly with less stable structures and is formed repeatedly during transcription, due …

Ii. Correlations Between Secondary Structure Stability And Mutation Frequency During Somatic Hypermutation, Barbara E. Wright, Karen H. Schmidt, Nick Davis, Aaron T. Hunt, Michael F. Minnick

Biological Sciences Faculty Publications

The role of secondary structures and base mutability at different levels of transcription and supercoiling is analyzed in variable region antibody genes VH5, VH94 and VH186.2. The data are consistent with a model of somatic hypermutation in which increasing levels of transcription and secondary structure stability correlate with the initial formation of successive mutable sites. Encoded differences exist in stem length and the number of GC pairs at low versus high levels of transcription in CDRs. These circumstances simplify the complexities of coordinating mutagenesis by confining this process to each mutable site successively, as they form in response to increasing …

Diversity And Morphological Variation In Formicidae In Three Strata Of The Monteverde Cloud Forest, August 2008, Peter A. Larson

Monteverde Institute: Tropical Ecology and Conservation

This study examines the arboreal presence of ants. Comparisons of diversity at three forest strata, canopy, mid-level, and forest floor were analyzed. Measurements were also made of leg length to body length and compared across the strata. The hypothesis is that arboreal ants will have a higher leg to body ratio. Finally a representation of each ant species, except three under-represented species was dropped from the canopy to test for the ability to “glide”. Conclusive results showed that ant diversity is greatest at the mid-stratum (H’ = 1.82). The remaining two strata, canopy and floor, showed similar diversity values (H’ …

Structure Of A Signal Transduction Regulator, Rack1, From Arabidopsis Thaliana, Hemayet Ullah

Department of Biology Faculty Publications

The receptor for activated C-kinase 1 (RACK1) is a highly conserved WD40 repeat scaffold protein found in a wide range of eukaryotic species from Chlamydymonas to plants and humans. In tissues of higher mammals, RACK1 is ubiquitously expressed and has been implicated in diverse signaling pathways involving neuropathology, cellular stress, protein translation, and developmental processes. RACK1 has established itself as a scaffold protein through physical interaction with a myriad of signaling proteins ranging from kinases, phosphatases, ion channels, membrane receptors, G proteins, IP3 receptor, and with widely conserved structural proteins associated with the ribosome. In the plant Arabidopsis thaliana, RACK1A …

Fundamental to this objective is developing an understanding of feedstock dynamics of crops suitable for cellulosic ethanol production. This report focuses on switchgrass, reviewing the existing literature from field trials across the United States, and compiling it for the first time into a single database. Data available from the literature included cultivar and crop …

Distinct Functions Of Autoreactive Memory And Effector Cd4+ T Cells In Experimental Autoimmune Encephalomyelitis, Wassim Elyaman, Pia Kivisäkk, Jay Reddy, Tanuja Chitnis, Khadir Raddassi, Jaime Imitola, Elizabeth Bradshaw, Vijay K. Kuchroo, Hideo Yagita, Mohamed H. Sayegh, Samia J. Khoury

Jay Reddy Publications

The persistence of human autoimmune diseases is thought to be mediated predominantly by memory T cells. We investigated the phenotype and migration of memory versus effector T cells in vivo in experimental autoimmune encephalomyelitis (EAE). We found that memory CD4⁺ T cells up-regulated the activation marker CD44 as well as CXCR3 and ICOS, proliferated more and produced more interferon-γ and less interleukin-17 compared to effector T cells. Moreover, adoptive transfer of memory T cells into T cell receptor (TCR)αβ^-/- recipients induced more severe disease than did effector CD4⁺ T cells with marked central nervous system inflammation and …

The Use Of An Integrated Geographical Information System At South African Airports, Claire Patterson-Abrolat

Bird Strike Committee-USA/Canada Joint Annual Meeting: 10th (2008)

The use of Geographic Information Systems (GIS) has, over the past few years, become an integral component of the operations at all airports owned and/or operated by the Airports Company South Africa (ACSA). What has however been lacking, is the application of this technology to practically manage and reduce risks out on the airfield. ACSA Bird and Wildlife Management has recently initiated a programme to utilize GIS and global positioning systems (GPS) on their airfields and all ACSA Wildlife Control Officers (WCOs) are now using handheld mobile computers with integrated GPS to record information and track their patrols out on …

Role Of Adenine In Thymine-Dimer Repair By Reduced Flavin-Adenine Dinucleotide, Guifeng Li, Vincent Sichula, Ksenija D. Glusac

Chemistry Faculty Publications

We present a study of excited-state behavior of reduced flavin cofactors using femtosecond optical transient absorption spectroscopy. The reduced flavin cofactors studied were in two protonation states: flavin-adenine dinucleotide (FADH(2) and FADH(-)) and flavin-mononucleotide (FMNH2 and FMNH-). We find that FMNH- exhibits multiexponential decay dynamics due to the presence of two bent conformers of the isoalloxazine ring. FMNH2 exhibits an additional fast deactivation component that is assigned to an iminol tautomer. Reduced flavin cofactors also exhibit a long-lived component that is attributed to the semiquinone and the hydrated electron that are produced in photoinduced electron transfer to the solvent. The …
