Using the self-efficacy literature as a theoretical framework, this article discusses the reality of academic achievement and academic performance among selected African American middle school girls. Both quantitative and qualitative research approaches are used to investigate the influence of selfefficacy. Thirty-seven African American middle school girls filled out an adversity questionnaire and also responded to the Children’s Self-efficacy Survey. Based on the results, 10 girls were selected for in-depth interviews. Responses to interview questions reveal how these girls’ self-efficacy helped them not only cope with obstacles in their lives but also excel academically. These responses provide important insights for educators …
Getting The Most Out Of Your Student Worker Budget: A Survey Of Tasks Performed By Student Assistants In Access Services Departments, Bradley P. Tolppanen, Janice Derr
Getting The Most Out Of Your Student Worker Budget: A Survey Of Tasks Performed By Student Assistants In Access Services Departments, Bradley P. Tolppanen, Janice Derr
Bradley P. Tolppanen
University libraries invest considerable funds and staff time in the hiring, training, and employment of student assistants. Access Services departments within university libraries depend on student assistants to complete tasks and aid in the work flow in virtually all areas of the department. With the recent increases in minimum wage and uncertain library budgets, the need for the most efficient and effective use of student assistants has become an even greater concern. This poster session will present the results of a recently conducted survey of Access Services department supervisors on the hiring, training, and duties assigned to student assistants. Results …

Bystander Intervention: From Small Steps To Large, Charles G. Eberly
Bystander Intervention: From Small Steps To Large, Charles G. Eberly
Charles G. Eberly
This short article was prepared for the 2008 National Hazing Prevention Week Resource Guide. The intent was to demonstrate to readers that even the smallest microaggressions have an impact on one's life, and resisting the temptations to tease a naive person for their lack of awareness or sensitivity is a good step on the way to confident bystander intervention when the consequences of hazing are far more damaging.
Impact Of Apoe Deficiency During Synaptic Remodeling In The Mouse Olfactory Bulb, Ikemefuna Nwosu, Salina Gairhe, Robert G. Struble, Britto P. Nathan
Impact Of Apoe Deficiency During Synaptic Remodeling In The Mouse Olfactory Bulb, Ikemefuna Nwosu, Salina Gairhe, Robert G. Struble, Britto P. Nathan
Britto P. Nathan
In this study we examined the role of apoE on the rate of synaptic recovery in the olfactory bulb (OB) following olfactory epithelium (OE) lesioning in mice. We used both immunoblotting and immunohistochemical techniques to compare the density of OB synaptophysin (Syn, a synaptic marker) in apoE-gene deficient/knockout (KO) mice and wild-type (WT) mice following OE lesion. We found that the whole bulb concentrations of Syn, measured by immunoblotting, declined sharply following injury in both WT and KO mice during the degenerative phase (3–7 days). After this initial decline, the Syn concentration gradually increased to normal levels by 56 days …
A Formative Evaluation Of A National Sorority's Recruitment Program In Its Inaugural Year, Colleen Elizabeth Coffey, Charles G. Eberly
A Formative Evaluation Of A National Sorority's Recruitment Program In Its Inaugural Year, Colleen Elizabeth Coffey, Charles G. Eberly
Charles G. Eberly
A formative evaluation of a national sorority's recruitment program was conducted to determine the effectiveness of selected program elements over the course of the first year's implementation. Primary objectives were to discover perceived needs among undergraduate members and chapters that were not met and to create program improvements based upon the respondent recommendations. A mixed method design employing a survey, the use of focus groups, and a review of available organizational recruitment data was utilized. Results indicated some participants understood and benefitted from the recruitment program, while others felt pressure to recruit, and still others appeared unaware of the program's …

Ports Of Slavery, Ports Of Freedom: How Slaves Used Northern Seaports’ Maritime Industry To Escape And Create Trans-Atlantic Identities, 1713-1783, Charles Foy
Charles Foy
This dissertation examines and reconstructs the lives of fugitive slaves who used the maritime industries in New York, Philadelphia and Newport to achieve freedom. It focuses on slaves during the period between 1713, the end of Queen Anne’s War, and 1783, the end of the American Revolution. While the study’s primary focus is on slavery in three port cities, it employs a broad geographic approach to consider how enslaved individuals in rural areas surrounding New York, Philadelphia and Newport, as well as slaves in more distant regions, used the maritime industry in northern port cities to escape slavery. Maritime work …
Masque Scenery And The Tradition Of Immobilization In The First Part Of The Countess Of Montgomery's Urania, Julie Campbell
Masque Scenery And The Tradition Of Immobilization In The First Part Of The Countess Of Montgomery's Urania, Julie Campbell
Julie Campbell
This study addresses two of the pivotal magical interventions in The First Part of The Countess of Montgomery's Urania, specifically those in which Wroth makes use of the masque tradition of immobilization: the Three Towers of the House of Love and the Marble Theatre on an island in the Gulf of Venice. In these enchantments, which include architecturally fantastic structures, music, and the symbolically posed, stilled characters, Wroth creates masque-like ‘idealized fictions’ that emblematize the romantic relationships she depicts. They are meant to elevate the sometimes sordid realities of real relationships to a higher allegorical plane on which the virtue …

Practicing Professional Communication Principles By Creating Public Service Announcements, Terri A. Fredrick
Practicing Professional Communication Principles By Creating Public Service Announcements, Terri A. Fredrick
Terri A. Fredrick
A PRIMARY GOAL of most introductory business and technical communication courses is to introduce students to the idea that the professional communication most of them will engage in is different from the writing they do for academic purposes. This overall idea covers several principles concerning professional writing. First, in an academic essay, a student may tell all he or she knows about a topic to an expert reader (the instructor); in professional writing situations, however, writers are most likely sharing only a small part of the information they know with nonexpert readers. Second, when writing in professional situations, writers must …
Calculation Of Phonon Dispersion In Semiconductor Nanostructures: An Undergraduate Computational Project, Jie Zou
Jie Zou
This paper discusses an undergraduate research project that involves the numerical calculation of phonon dispersion in semiconductor nanostructures. Phonon dispersion is calculated in the elastic continuum approximation by applying a finite-difference method to solving the elastic wave equation with boundary conditions. Students did simulations for two nanostructures: a free-standing GaN thin film and a free-standing AlN/GaN/AlN heterostructure. A comparison of these two structures helps students understand the effect of boundary conditions on the nature of the phonon dispersion. The project is related to current research in phonon thermal transport in semiconductor nanostructures and nanodevices.
C^1 Actions Of The Mapping Class Group On The Circle, Kamlesh Parwani
C^1 Actions Of The Mapping Class Group On The Circle, Kamlesh Parwani
Kamlesh Parwani
Let S be a connected orientable surface with finitely many punctures, finitely many boundary components, and genus at least 6. Then any C^1 action of the mapping class group of S on the circle is trivial. The techniques used in the proof of this result permit us to show that products of Kazhdan groups and certain lattices cannot have C^1 faithful actions on the circle. We also prove that for n > 5, any C^1 action of Aut(F_n) or Out(F_n) on the circle factors through an action of Z/2Z.
Expansion Of Golf Courses In The United States, Darrell E. Napton, Chris Laingen
Expansion Of Golf Courses In The United States, Darrell E. Napton, Chris Laingen
Chris Laingen
Twenty-five million Americans play golf on the nation's 16,000 courses each year. These golf courses constitute a significant national landscape feature. Since 18789, when the game arrived in the United States, golf has filtered down the urban, economic, and social hierarchies to become accepted by and accessible to most Americans. During the ensuing thirteen decades the number, location, and layout of the nation's golf courses have responded to many of the same driving forces that impacted the nation, including decentralization, growth of the middle class, war, economic depression, suburbanization, and the increasing role of the federal government. Four epochs of …
Phylogenetic Utility Of Ycf1 In Orchids: A Plastid Gene More Variable Than Matk, Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams, Michael Moore
Phylogenetic Utility Of Ycf1 In Orchids: A Plastid Gene More Variable Than Matk, Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams, Michael Moore
Barbara S. Carlsward
Plastid DNA sequences have been widely used by systematists for reconstructing plant phylogenies. The utility of any DNA region for phylogenetic analysis is determined by ease of amplification and sequencing, confidence of assessment in phylogenetic character alignment, and by variability across broad taxon sampling. Often, a compromise must be made between using relatively highly conserved coding regions or highly variable introns and intergenic spacers. Analyses of a combination of these types of DNA regions yield phylogenetic structure at various levels of a tree (i.e., along the spine and at the tips of the branches). Here, we demonstrate the phylogenetic utility …
Vegetative Anatomy Of Calypsoeae (Orchidaceae), William Louis Stern, Barbara S. Carlsward
Vegetative Anatomy Of Calypsoeae (Orchidaceae), William Louis Stern, Barbara S. Carlsward
Barbara S. Carlsward
Calypsoeae represent a small tribe of anatomically little-known orchids with a wide distribution in the Western Hemisphere. Leaves are present in all genera, except Corallorhiza and Wullschlaegelia both of which are subterranean taxa. Stomata are abaxial (ad- and abaxial in Aplectrum) and tetracytic (anomocytic in Calypso). Fiber bundles are absent in leaves of all taxa examined except Govenia tingens. Stegmata are present in leaves of only Cremastra and Govenia. Roots are velamentous, except in filiform roots of Wullschlaegelia. Vegetative anatomy supports a relationship between Wullschlaegelia and Corallorhiza but does not support the grouping of winter-leaved Aplectrum and Tipularia nor proposed …

Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom
Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom
Paul V. Switzer
Males of many species guard their mates to prevent rivals from usurping paternity of the potential offspring. Environmental conditions, such as temperature, may affect a male’s ability to guard a female effectively and consequently the amount of sperm competition that occurs. We tested whether temperature and light affected mating behavior in laboratory experiments on the Japanese beetle, Popillia japonica Newman, a species in which males guard females for minutes to many hours after mating. When tested in groups, under conditions of high temperature and high light, males guarded females for shorter periods of time and males and females both mated …
Molybdate Treatment And Sulfate Starvation Decrease Atp And Dna Levels In Ferroplasma Acidarmanus, Kai F. Hung
Molybdate Treatment And Sulfate Starvation Decrease Atp And Dna Levels In Ferroplasma Acidarmanus, Kai F. Hung
Kai F. Hung
Sulfate is a primary source of sulfur for most microbes and in some prokaryotes it is used an electron acceptor. The acidophile Ferroplasma acidarmanus (strain fer1) requires a minimum of 150 mM of a sulfate-containing salt for growth. Sulfate is assimilated by F. acidarmanus into proteins and reduced to form the volatile organic sulfur compounds methanethiol and dimethyldisulfide. In the absence of sulfate, cell death occurs by an unknown mechanism. In this study, cell viability and genomic DNA and ATP contents of F. acidarmanus were monitored in response to the absence of sulfate or the presence of sulfate and the …
Old Acetogens, New Light, Steven L. Daniel, Harold L. Drake, Anita S. Gößner
Old Acetogens, New Light, Steven L. Daniel, Harold L. Drake, Anita S. Gößner
Steven L. Daniel
Acetogens utilize the acetyl-CoA Wood-Ljungdahl pathway as a terminal electron-accepting, energy-conserving, CO2-fixing process. The decades of research to resolve the enzymology of this pathway (1) preceded studies demonstrating that acetogens not only harbor a novel CO2-fixing pathway, but are also ecologically important, and (2) overshadowed the novel microbiological discoveries of acetogens and acetogenesis. The first acetogen to be isolated, Clostridium aceticum, was reported by Klaas Tammo Wieringa in 1936, but was subsequently lost. The second acetogen to be isolated, Clostridium thermoaceticum, was isolated by Francis Ephraim Fontaine and co-workers in 1942. C. thermoaceticum became the most extensively studied acetogen and …

Sometimes It’S A Child And A Choice: Toward An Embodied Abortion Praxis, Jeannie Ludlow
Sometimes It’S A Child And A Choice: Toward An Embodied Abortion Praxis, Jeannie Ludlow
Jeannie Ludlow
Feminist analyses of recent abortion politics in the United States note that the “abortion debate” has settled into a system of dichotomies, such as the dichotomy between women’s autonomy on the abortion rights side and the value of unborn life on the anti-abortion side. This article posits that these dichotomizations contribute to the erosion of women’s access and rights to abortion through loss of credibility for abortion rights discourse and loss of access to abortion praxis that can handle more complex situations. Maintenance of the dichotomies requires denial or erasure of more complicated situations, like late-second-trimester abortion and situations in …

The Two Variable Substitution Problem For Free Products Of Groups, Leo P. Comerford, Charles C. Edmunds
The Two Variable Substitution Problem For Free Products Of Groups, Leo P. Comerford, Charles C. Edmunds
Leo Comerford
We consider equations of the form W(x,y) = U with U an element of a free product G of groups. We show that with suitable algorithmic conditions on the free factors of G, one can effectively determine whether or not the equations have solutions in G. We also show that under certain hypotheses on the free factors of G and the equation itself, the equation W(x,y) = U has only finitely many solutions, up to the action of the stabilizer of W(x,y) in Aut().
Spatial And Temporal Expression Profiling Of Cell-Wall Invertase Genes During Early Development In Hybrid Poplar, Thomas Canam, Sarah W.Y. Mak, Shawn D. Mansfield
Spatial And Temporal Expression Profiling Of Cell-Wall Invertase Genes During Early Development In Hybrid Poplar, Thomas Canam, Sarah W.Y. Mak, Shawn D. Mansfield
Thomas Canam
Cell-wall invertase genes are spatially and temporally regulated in several plant species, including Daucus carota L., Lycopersicon esculentum L. and Solanum tuberosum L. However, few studies of cell-wall invertase genes of trees have been conducted, despite the importance of trees as a source of lignocellulosic biopolymers.We identified three putative cell-wall invertase genes in hybrid poplar (Populus alba L. × grandidentata Michx.) that showed higher homology to each other than to cell-wall invertases of other dicotyledonous species, with two of the genes (Pa×gINV2 and Pa×gINV3) appearing as a genomic tandem repeat. These genes are more similar to each other than to …

The Effects Of Curvature On Haptic Judgments Of Extent In Sighted And Blind People, Morton A. Heller, Astrid M.L. Kappers, Melissa Mccarthy, Ashley Clark, Tara Riddle, Erin Fulkerson, Lindsay Wemple, Anne Mcclure Walk, Andreana Basso, Crystal Wanek, Kristen Russler
Morton A. Heller
A series of experiments was carried out to examine the effect of curvature on haptic judgments of extent in sighted and blind individuals. Experiment 1 showed that diameters con- necting the endpoints of semicircular lines were underestimated with respect to straight lines, but failed to show an effect of visual experience on length judgments. In experiment 2 we tested arc lengths. The effects of curvature on perceived path length were weaker, but were still present in this experiment.Visual experience had no effect on path length judgments. Another experiment was performed to examine the effect of repeated tracing (1, 5, 9, …
Facilitating Better Teamwork: Analyzing The Challenges And Strategies Of Classroom-Based Collaboration, Terri A. Fredrick
Facilitating Better Teamwork: Analyzing The Challenges And Strategies Of Classroom-Based Collaboration, Terri A. Fredrick
Terri A. Fredrick
To help students develop teamwork skills, teachers should be aware of the strategies students already employ to assert authority and manage conflict. Researchers studying engineering students have identified two such approaches: transfer-of-knowledge sequences, in which students emulate teacher and pupil roles; and collaborative sequences, in which students use circular talk to reach consensus. As demonstrated in this article, these strategies are also used by students in professional communication courses. The second half of this article provides specific suggestions for designing team assignments, interacting effectively with student teams, and developing evaluations that value the process of teamwork.
