Clouds, Cameras, And Computers: The First Amendment And Networked Public Places, Timothy Zick

Faculty Publications

It seems to be a common assumption that physical places like parks, sidewalks, and public squares, and "cyber-places" like the Web, constitute separate locations of communication. In reality, however, the intersection and collision of these two spaces is imminent. In some respects it has already occurred. Entire cities and counties are erecting wireless "clouds" that will bring the Internet to vast public spaces. Technologies of surveillance continue to proliferate. What one does and says in public places is increasingly subject to surveillance by means of a combination of hand-held devices and official surveillance tools like closed circuit television cameras (CCTV). …

A Cognitive Robotics Approach To Comprehending Human Language And Behaviors, Deryle W. Lonsdale, D. Paul Benjamin, Damian Lyons

Faculty Publications

The ADAPT project is a collaboration of researchers in linguistics, robotics and artificial intelligence at three universities. We are building a complete robotic cognitive architecture for a mobile robot designed to interact with humans in a range of environments, and which uses natural language and models human behavior. This paper concentrates on the HRI aspects of ADAPT, and especially on how ADAPT models and interacts with humans.

Biogeography And The Cambrian Radiation Of Arachnomorph Arthropods, Jonathan R. Hendricks, Bruce S. Lieberman

Faculty Publications

Biogeographic patterns in primarily Cambrian arachnomorph taxa are investigated using a recently constructed phylogenetic hypothesis in order to explore the biogeographic context of the Cambrian radiation. A modified version of Brooks Parsimony Analysis is employed to elucidate patterns of vicariance and geodispersal in taxa from six regions (Laurentia, Baltica, Siberia, Australia, Africa and China). Well resolved vicariance and geodispersal trees are very similar and reconstruct Laurentia and China as sister areas. This close area relationship between Laurentia and China provides extensive evidence for congruent vicariance and range expansion in Cambrian arachnomorphs, while data from trilobites do not show this pattern. …

La Discussió Deliberativa: Usar El Discurs De Classe Per Promoure El Pensament Crític, Mark Felton

Faculty Publications

Per potenciar el pensament creatiu a classe cal comprendre les arrels d’aquest pensament en el raonament argumentatiu. El pensament crític inclou la recerca i l’avaluació de les raons que hi ha darrere d’una afirmació. Per prendre part en aquesta activitat d’investigació, cal entendre els elements sobre els quals es discuteix i com aquests es combinen per justificar una conclusió. Les investigacions es mostren cada vegada més unànimes en el fet que els estudiants experimenten una millora substancial en el desenvolupament del pensament crític (i que aquesta millora es transfereix també a nous temes) a mesura que van adquirint experiència en …

Utilizing Focus Groups To Evaluate An Information Literacy Program In A General Biology Course, Betsy S. Hopkins

Faculty Publications

The Harold B. Lee Library at Brigham Young University (BYU) recently implemented a number of information literacy strategies to help students in Biology 100, a large general education class, find resources for their term assignment. The library's services for Biology 100 students were evaluated using focus groups composed of both teaching assistants and students. This paper will describe the class and the assignment, discuss the impact the class had on library staff, detail the efforts of the staff to meet the needs of Biology 100 students, and present results of focus groups used to evaluate the library's outreach and teaching …

Missing The Link: The Importance Of Keeping Ecosystems Intact And What The Endangered Species Act Suggests We Do About It, Kalyani Robbins

Faculty Publications

The Endangered Species Act was created in response to a rapid decline in species biodiversity. Although Congress chose direct protection of individual species as its tool, protecting ecosystems (a necessary component of biodiversity) was clearly one of the goals for which that tool was to be used. A species can be abundant in some areas and declining in others, such that protecting the entire species does not make sense. Congress dealt with this issue by amending the Endangered Species Act in 1978 to allow for protection of “distinct population segments,” thereby allowing the population in decline to be protected in …

Empty Threats? How Egyptians' Self-Ontology Should Affect The Way We Read Many Texts, Kerry M. Muhlestein

Faculty Publications

Egyptologists have typically divided texts into those that dealt with the divine and those that treated the mundane. This false dichotomy is not one that the Egyptians themselves would have imposed. They saw themselves as mortal beings that interacted with the divine realm and the afterlife. The texts they created reflect this understanding, and thus we are greatly hampered when we insist that the language of a decree, threat formula, or other texts, must refer to either the mundane or the supernatural, but not both. There is ample evidence that the Egyptians often intended specific wording to invoke multiple realms, …

Genetic Diversity And Low Reproductive Success In Isolated Populations Of Utah Juniper (Juniperus Osteosperma, Cupressaceae), Loreen Allphin, Val J. Anderson, Amy F. Hunt

Faculty Publications

Utah juniper (Juniperus osteosperma) has greatly expanded its historical range in the western United States. Management plans for the species have focused on curtailing its encroachment into sagebrush and grassland communities. These plans often include burning or other methods of elimination. These methods may result in subdivision or fragmentation of existing juniper stands. We initiated a study at Dugway Proving Ground, a U.S. Army facility, to examine the effects of fragmentation on the reproductive success of Utah juniper in isolated populations. We used enzyme electrophoresis to quantify genetic variability in isolated populations. We also determined population reproductive success by examining …

Conditional Discrimination And Reversal In Amnesia Subsequent To Hypoxic Brain Injury Or Anterior Communicating Artery Aneurysm Rupture, C. E. Myers, J. Deluca, Ramona O. Hopkins, M. A. Gluck

Faculty Publications

Human anterograde amnesia can develop following bilateral damage to the hippocampus and medial temporal lobes, as in hypoxic brain injury, or following damage to the basal forebrain, as following anterior communicating artery (ACoA) aneurysm rupture. In both cases, the mnestic deficit may be similar when assessed by standard neuropsychological measures. However, animal and computational models suggest that there are qualitative differences in the pattern of impaired and spared memory abilities following damage to hippocampus versus basal forebrain. Here, we show such a dissociation in human amnesia using a single two-stage task, involving conditional discrimination and reversal. Consistent with a prior …

Brain Integrity And Cerebral Atrophy In Vietnam Combat Veterans With And Without Posttraumatic Stress Disorder, Bruce L. Brown, Dawson W. Hedges, G. William Thatcher, Pamela J. Bennett, Shabnam Sood, David Paulson, Sarah Creem-Regehr, Steven Allen, Jamie Johnson, Brooke Froelich, Erin D. Bigler

Faculty Publications

Posttraumatic stress disorder (PTSD) is associated with decreased hippocampal volume, but the relationship between trauma and brain morphology in the absence of PTSD is less clear. In this study, measures of brain integrity were determined by estimating gray and white matter regional brain volumes using structural magnetic resonance imaging in six patients with PTSD and in five controls with comparable trauma exposure but without clinical evidence of PTSD. The only statistically significant volume difference between groups was observed multivariately in the white matter of the right temporal lobe (superior temporal gyrus, fusiform gyrus, parahippocampal gyrus, white-matter stem, middle temporal gyrus, …

Turning The Hearts Of Fathers To Their Children: Why Religious Involvement Can Make A Difference, Loren Marks, David C. Dollahite

Faculty Publications

Charles Dickens, the English author and keen observer of human affairs, wrote of revolution-era France: "It was the best of times, it was the worst of times." In many ways, Dickens' dichotomy regarding "the best of times" and "the worst of times" captures the state of contemporary American fatherhood. Many fathers are more highly involved with their children than the fathers of past generations. Conversely, many other fathers are disconnected from or uninvolved with their children. For many of the fathers who are highly involved in their children's lives, their religious faith is a motivational influence.

Jesus, The Great Shepherd-King, Dana M. Pike

Faculty Publications

“The Lord is my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters” (Psalm 23:1–2). So begins one of the most beloved psalms and best-known biblical passages mentioning a shepherd. Shepherd imagery is utilized in scripture to depict three important aspects of Jesus’s identity and mission: His roles as Savior, King, and Jehovah, the God of Israel. Of these three, His role as compassionate Savior, devoted to protecting and saving the flock of God, is the aspect of shepherd symbolism that typically comes to mind. Less well known, …

A New View Of Ridge Segmentation And Near-Axis Volcanism At The East Pacific Rise, 8˚–12˚N, From Em300 Multibeam Bathymetry, Scott M. White, Rachel M. Haymon, S M. Carbotte

Faculty Publications

New, high-resolution bathymetry for the East Pacific Rise between 8˚N and 12˚N was collected over a6 km wide swath centered on the ridge axis using the 30 kHz Simrad EM300 multibeam system. Thecoverage area corresponds latitudinally to the designated Ridge2000 Integrated Studies Site (ISS) for fastspreading ridges. The EM300 data, gridded at 30 m latitude by 50 m longitude, represent a greater than 4Ximprovement in horizontal resolution over previously available multibeam data and a 2X improvement indepth resolution. The new bathymetry was used to update the locations and hierarchy of ridge offsets forthis area. Among the many applications for this …

Performance Of The Nzi And Other Traps For Biting Flies In North America, S. Mihok, D. A. Carlson, E. S. Krafsur, L. D. Foil

Faculty Publications

The performance of Nzi traps for tabanids (Tabanus similis Macquart, T. quinquevittatus Wiedemann, Chrysops aberrans Philip, C. univittatus Macquart, C. cincticornis Walker, Hybomitra lasiophthalma (Macquart)), stable flies (Stomoxys calcitrans Linnaeus) (Diptera: Muscidae) and mosquitoes (Aedes) (Diptera: Culicidae) was investigated at various sites in Canada (Ontario, Alberta) and USA (Iowa, Florida, Louisiana). Traps made from selected fabrics, insect nettings and hand-dyed blue cotton were compared to the African design to provide practical recommendations for temperate environments. Comparisons of substituted materials showed that trap performance was optimal only when traps were made from appropriate fabrics in the colours produced by either copper …

Amyloid-Β-Induced Pathological Behaviors Are Suppressed By Ginkgo Biloba Extract Egb 761 And Ginkgolides In Transgenic Caenorhabditis Elegans, Yanjue Wu, Zhixin Wu, Peter Butko, Yves Christen, Mary P. Lambert, William L. Klein, Christopher D. Link, Yuan Luo

Faculty Publications

Amyloid-β (Aβ) toxicity has been postulated to initiate synaptic loss and subsequent neuronal degeneration seen in Alzheimer's disease (AD). We previously demonstrated that the standardized Ginkgo biloba extract EGb 761, commonly used to enhance memory and by AD patients for dementia, inhibits Aβ-induced apoptosis in neuroblastoma cells. In this study, we use EGb 761 and its single constituents to associate Aβ species with Aβ-induced pathological behaviors in a model organism, Caenorhabditis elegans. We report that EGb 761 and one of its components, ginkgolide A, alleviates Aβ-induced pathological behaviors, including paralysis, and reduces chemotaxis behavior and 5-HT hypersensitivity in a transgenic …

Rapid Decay Of Tree-Community Composition In Amazonian Forest Fragments, William F. Laurance, Henrique E.M. Nascimento, Susan G. Laurance, Ana Andrade, José E.L.S. Ribeiro, Juan Pablo Giraldo, Thomas E. Lovejoy, Richard Condit, Jerome Chave, Kyle E. Harms, Sammya D'Angelo

Faculty Publications

Forest fragmentation is considered a greater threat to vertebrates than to tree communities because individual trees are typically long-lived and require only small areas for survival. Here we show that forest fragmentation provokes surprisingly rapid and profound alterations in Amazonian tree-community composition. Results were derived from a 22-year study of exceptionally diverse tree communities in 40 1-ha plots in fragmented and intact forests, which were sampled repeatedly before and after fragment isolation. Within these plots, trajectories of change in abundance were assessed for 267 genera and 1,162 tree species. Abrupt shifts in floristic composition were driven by sharply accelerated tree …

A Novel Account Of Scientific Anomaly: Help For The Dispute Over Low-Dose Biochemical Effects, Kevin C. Elliott

Faculty Publications

The biological effects of low doses of toxic and carcinogenic chemicals are currently a matter of significant scientific controversy. This paper argues that philosophers of science can contribute to alleviating this controversy by examining it with the aid of a novel account of scientific anomaly. Specifically, analysis of contemporary research on chemical hormesis (i.e.. alleged beneficial biological effects produced by low doses of substances that are harmful at higher doses) suggests that scientists may initially describe anomalous phenomena in terms of multiple distinct '"characterizations," each
of which is compatible with current empirical evidence. By focusing attention on this feature of …

The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male response to the …

Changes In Understory Vegetation Of A Ponderosa Pine Forest In Northern Arizona 30 Years After A Wildfire, Amanda L. Bataineh, Brian P. Oswald, Mohammad M. Bataineh, Hans M. Williams, Dean W. Coble

Faculty Publications

Wildland fires can cause shifts in understory species composition and production. Many studies have examined short-term changes in understory vegetation following a wildfire; however, very few long term studies are available. The objective of this study was to examine changes in understory (herb and shrub) species composition and production since the 1972 Rattle Burn wildfire on the Coconino National Forest near Flagstaff, Arizona. Understory species composition and production were originally sampled in 1972, 1974, and 1980 and were re-sampled during July and August of 2002 and 2003 on 30 plots in each of four sites: high severity burn, low severity …

Estradiol Interactions With Dopamine Antagonists In Mares: Prolactin Secretion And Reproductive Traits, K. K. Kelley, D. L. Thompson, W. A. Storer, P. B. Mitcham, R. M. Gilley, P. J. Burns

Faculty Publications

Two experiments studied the effects of pretreatment with estradiol benzoate before treatment with a dopamine antagonist on prolactin secretion and reproductive traits in mares during (1) the seasonal anovulatory period and (2) the normal breeding season. Experiment 1 was performed in winter with 17 mares selected for low follicular activity. Nine mares received estradiol benzoate injections every other day for a total of 10 injections; 8 mares received similar injections of vehicle. Ten days after onset of injections, all mares were placed on daily injections of sulpiride (250 mg) for 35 days or until ovulation. Plasma prolactin concentrations were higher …

Siamese, A Plant-Specific Cell Cycle Regulator, Controls Endoreplication Onset In Arabidopsis Thaliana, Michelle L. Churchman, Matthew L. Brown, Naohiro Kato, Viktor Kirik, Martin Hülskamp, Dirk Inzé, Lieven De Veylder, Jason D. Walker, Ui Zheng, David G. Oppenheimer, Taylor Gwin, Jason Churchman, John C. Larkin

Faculty Publications

Recessive mutations in the SIAMESE (SIM) gene of Arabidopsis thaliana result in multicellular trichomes harboring individual nuclei with a low ploidy level, a phenotype strikingly different from that of wild-type trichomes, which are single cells with a nuclear DNA content of ∼16C to 32C. These observations suggested that SIM is required to suppress mitosis as part of the switch to endoreplication in trichomes. Here, we demonstrate that SIM encodes a nuclear-localized 14-kD protein containing a cyclin binding motif and a motif found in ICK/KRP (for interactors of Cdc2 kinase/Kip-related protein) cell cycle inhibitor proteins. Accordingly, SIM was found to associate …

Analysis And Functional Annotation Of Expressed Sequence Tags From The Fall Armyworm Spodoptera Frugiperda, Youping Deng, Yinghua Dong, Venkata Thodima, Rollie J. Clem, A. Lorena Passareli

Faculty Publications

Background

Little is known about the genome sequences of lepidopteran insects, although this group of insects has been studied extensively in the fields of endocrinology, development, immunity, and pathogen-host interactions. In addition, cell lines derived from Spodoptera frugiperda and other lepidopteran insects are routinely used for baculovirus foreign gene expression. This study reports the results of an expressed sequence tag (EST) sequencing project in cells from the lepidopteran insect S. frugiperda, the fall armyworm.

Results

We have constructed an EST database using two cDNA libraries from the S. frugiperda-derived cell line, SF-21. The database consists of 2,367 ESTs …

Spatial Confidentiality And Gis: Re-Engineering Mortality Locations From Published Maps About Hurricane Katrina, Andrew J. Curtis, Jacqueline W. Mills, Michael Leitner

Faculty Publications

Background: Geographic Information System (GIS) can provide valuable insight into patterns of human activity. Online spatial display applications, such as Google Earth, can democratise this information by disseminating it to the general public. Although this is a generally positive advance for society, there is a legitimate concern involving the disclosure of confidential information through spatial display. Although guidelines exist for aggregated data, little has been written concerning the display of point level information. The concern is that a map containing points representing cases of cancer or an infectious disease, could be re-engineered back to identify an actual residence. This is …

Alienated Catholics: Establishing The Groundwork For Dialogue, Catherine M. Murphy

Faculty Publications

One of the earliest arguments against women's ordination the U.S. Conference of Catholic Bishops articulated in 1972 was that, since the incarnation of God was in a male, this culminates in a male priesthood. This reflects a hierarchical anthropology well-known from Christianity's earliest encounters with the Greco-Roman world, whereby the male was associated with the mind, reason, and the spirit, while the female was associated with the body, passion, and the material world.¹ In fact, some Greek doctors and philosophers thought that every fetus began as a male, but those that didn't develop fully became female.² Thomas Laqueur …
