Work As A Manifestation Of Faith In The English Nunnery: Barking Abbey, Essex, Terri Barnes

Quidditas

This paper discusses various occupations held by nuns in the late-medieval and early-modern English convent, and argues that while the nuns did have extraordinary opportunities for self-management when compared to secular women, nuns carried out those responsibilities in part as extensions and expressions of their faith. This paper looks at offices held by the nuns at Barking Abbey in Essex, from the late Medieval period up to the Abbey’s dissolution in the sixteenth century as a result of the shifting political and religious sands under King Henry VIII. Barking Abbey was a large, wealthy institution that needed capable administration, and …

Necessity Of Hippocampal Neurogenesis For The Therapeutic Action Of Antidepressants In Adult Nonhuman Primates, Tarique D. Perera, Andrew J. Dwork, Kathryn A. Keegan, Lakshmi Thirumangalakudi, Cecilia M. Lipira, Niamh Joyce, Christopher Lange, James Dee Higley, Gorazd Rosoklija, Rene Hen, Harold A. Sackeim, Jeremy D. Coplan

Faculty Publications

Background: Rodent studies show that neurogenesis is necessary for mediating the salutary effects of antidepressants. Nonhuman primate (NHP) studies may bridge important rodent findings to the clinical realm since NHP-depression shares significant homology with human depression and kinetics of primate neurogenesis differ from those in rodents. After demonstrating that antidepressants can stimulate neurogenesis in NHPs, our present study examines whether neurogenesis is required for antidepressant efficacy in NHPs. Materials/Methodology: Adult female bonnets were randomized to three social pens (N = 6 each). Pen-1 subjects were exposed to control-conditions for 15 weeks with half receiving the antidepressant fluoxetine and the rest …

Identity Negotiating: Redefining Stigmatized Identities Through Adaptive Sports And Recreation Participation Among Individuals With A Disability, Neil R. Lundberg, Stacy Taniguchi, Bryan P. Mccormick, Catherine Tibbs

Faculty Publications

The purpose of this study was to investigate the meanings and outcomes of adaptive sport and recreation participation among individuals with disabilities. In-depth open-ended interviews were conducted with 17 individuals. Analysis of the data followed qualitative data analysis and classical grounded theory utilizing line by line coding, identification of emergent themes, and identification of a core category grounded in the data. Results indicated that participants felt stigmatized and stereotyped, but their adaptive sports and recreation participation provided them with opportunities to build social networks, experience freedom and success, positively compare themselves with others without disabilities, and feel a sense of …

A Web Of Knowledge: A Conceptual-Modeling Perspective, David W. Embley, Stephen W. Liddle, Cui Tao

Faculty Publications

The current web is a web of linked pages. Frustrated users search for facts by guessing which keywords or keyword phrases might lead them to pages where they can find facts. Can we make it possible for users to search directly for facts? Equivalently, can we turn the web into a web of facts (instead of a web of pages containing facts)? Ultimately, can the web be a knowledgebase—a web of knowledge—that can provide direct answers to factual questions and also provide the confidence necessary to make those answers believable? We answer these questions by showing how to superimpose a …

Firm Size Matters: An Empirical Investigation Of Organizational Size And Ownership On Sustainability- Related Behaviors, Peter Jack Gallo, Lisa Jones Christensen

Faculty Publications

The phrase “corporate sustainability” is increasingly prevalent in both the industry press and management journals (Engardio, 2007; Montiel, 2008). Corporate sustainability pledges and reports are also increasingly prevalent, yet empirical studies on how top managers define and enact the construct are lacking. To address this deficiency, we investigate how firms define, support, and report their sustainability efforts. In a large sample (N = 922) study of accounting executives at U.S.-based firms, we find evidence that organizational size, ownership, and industry are strongly related with support mechanisms and reporting of sustainability.

New But Hardly Improved: Are Multiple Retranslations Of Classics The Best Cultural Use To Make Of Translation Talent?, Timothy D. Sergay

Russian Language Journal

The notion of audio remastering seems to inform the way literary “consumers” conceive of retranslations of classic works today. This is almost certainly because the two operations—remastering and retranslation—are such natural cousins. Retranslation seems to imply, at the very least, continuous improvement of the literary product in the target language, that is, the elimination of earlier translators’ errors in construing the source text and the ever more adequate recreation of the original author’s stylistics. How close this seems to the idea of “cleaning up” an audio signal, improving the “signal‐to‐noise ratio,” enhancing fidelity—this critical term, along with loss, is common …

You Can Lead Them To Water, But You Can’T Make Them Drink: Using Crowd Sourcing To Lead Library Patrons To Extended Library Services Relevant To Their Search Criteria, William B. Lund, Chad Hansen

Faculty Publications

The Lee Library at Brigham Young University has extensive resources in the forms of highly skilled subject librarians, print resources and digital collections, but getting the students to be aware of and use them effectively is a problem. To help inform library patrons of these resources librarian subject specialists have created over 150 subject guides using LibGuides for subject areas, classes, and some subspecialties, which was an enormous task; but are these resources being used effectively? This paper explores and reports on a subject guide recommender system, which recommends relevant subject guides based on patron searches, using a crowd sourced …

Digital Technology And The Variation In Design Routines: A Sequence Analysis Of Four Design Processes, James Gaskin, B. Veeresh Thummadi, Kalle Lyytinen, Youngjin Yoo

Faculty Publications

We advance a theory of design process variation across organizational types and the effects of digitalization on these processes. We argue that design routines are subject to greater variation within and between organizations as organizations embed increasingly rich repertoires of digital capabilities in their design activities. Using a sequence analysis method we compare design process variation in four organizations to examine how design routines vary due to differences in embedded digital capabilities and organization of the design process. Our analysis reveals new insights on the effects organizational context and digitalization have on design routine composition.

Conceptual Modeling Foundations For A Web Of Knowledge, David W. Embley, Stephen W. Liddle, Deryle W. Lonsdale

Faculty Publications

The semantic web purports to be a web of knowledge that can answer our questions, help us reason about everyday problems as well as scientific endeavors, and service many of our wants and needs. Researchers and others expound various views about exactly what this means. Here we propose an answer with conceptual modeling as its foundation. We define a web of knowledge as a collection of interconnected knowledge bundles superimposed over a web of documents. Knowledge bundles are conceptual model instances augmented with facilities that provide for both extensional and intensional facts, for linking between knowledge bundles yielding a web …

The Influence Of Depressive Symptomatology And Perceived Stress On Plasma And Salivary Oxytocin Before, During And After A Support Enhancement Intervention, Wendy C. Birmingham, Julianne Holt-Lunstad, Kathleen C. Light

Faculty Publications

Oxytocin (OT) activity increases in response to stress as well as to warm social contact. Subclinical depression is associated with higher stress but less reward from social contacts. The present investigation was intended to examine whether husbands and wives with high depressive symptomatology scores have increased plasma and salivary OT that may be mediated partly by higher perceived stress, and also to assess whether an intervention to convey partner support through ‘‘warm touch’’ may reduce effects of depressive symptoms on OT. In this study, 34 healthy married couples (n = 68) ages 20—39 provided self reports of depressive symptoms (CESD) …

The Interpersonal Theory Of Suicide, Scott R. Braithwaite, Kimberly Van Orden, Tracy K. Witte, Kelly C. Cukrowicz, Edward A. Selby, Thomas E. Joiner Jr.

Faculty Publications

Suicidal behavior is a major problem worldwide and at the same time has received relatively little empirical attention. This relative lack of empirical attention may be due in part to a relative absence of theory development regarding suicidal behavior. The current paper presents the Interpersonal Theory of Suicidal Behavior. We propose that the most dangerous form of suicidal desire is caused by the simultaneous presence of two interpersonal constructs—thwarted belongingness and perceived burdensomeness (and hopelessness about these states)—and further, that the capability to engage in suicidal behavior is separate from the desire to engage in suicidal behavior. According to the …

Social Support And The Reactivity Hypothesis: Conceptual Issues In Examining The Efficacy Of Received Support During Acute Psychological Stress, Wendy C. Birmingham, Bert N. Uchino, Mckenzie Carlisle, Allison A. Vaughn

Faculty Publications

Social support has been reliably related to better physical health outcomes. One influential model suggests that social support is related to lower cardiovascular disease mortality because it reduces the potentially deleterious consequences of cardiovascular reactivity during acute stress. However, received support and perceived support are separable constructs and epidemiological research suggests variability in links between received support and health. This is important because most social support and acute laboratory stress studies are essentially based on the receipt of support. In this paper, we focus on the conceptualization of received support and its implications for understanding links to support laboratory reactivity …

Religiosity In Adolescence And Emerging Adulthood, Carolyn Mcnamara Barry, Larry J. Nelson

Faculty Publications

According to IEA Civic Education Study, approximately half of American adolescents participate in religious groups (Torney-Purta et al. 2001) and half of American 18–24-year-olds report religious beliefs to be important (Inglehart et al. 2004). Thus, religious experiences are an important aspect of the lives of many adolescents and emerging adults (approximately ages 18 to the mid-20s) in the USA. Specifically, adolescents are fully immersed in identity exploration and ideally resolve this search in emerging adulthood. They embark on a quest to solidify their values and beliefs about countless issues, including religiosity. This essay will review the literature on religiosity among …

Understanding Streaming In Dictyostelium Discoideum: Theory Versus Experiments, J. C. Dallon, Brittany Dalton, Chelsea Malani

Faculty Publications

Recent experimental work involving Dictyostelium discoideum seems to contradict several theoretical models. Experiments suggest that localization of the release of the chemoattractant cyclic adenosine monophosphate to the uropod of the cell is important for stream formation during aggregation. Yet several mathematical models are able to reproduce streaming as the cells aggregate without taking into account localization of the chemoattractant. A careful analysis of the experiments and the theory suggests the two major features of the system which are important to stream formation are random cell motion and chemotaxis to regions of higher cell density. Random cell motion acts to reduce …

Strategies To Resolve The Three-Dimensional Structure Of The Genome Of Small Single-Stranded Icosahedral Viruses, Eduardo Sanz Garcia

Theses and Dissertations

The aim of this study is the three-dimensional structural characterization of the genome packaging inside viral capsids via cryo-electron microscopy and three-dimensional reconstruction. The genome of some single-stranded viruses can be densely packaged within their capsid shells. Several stretches of the genome are known to adopt stable secondary structures, however, to date, little is known about the three-dimensional organization of the genome inside their capsid shells. Two techniques have been developed to facilitate the structural elucidation of genome packaging: the asymmetric random-model method, and the symmetry-mismatch, random model method. Both techniques were successfully tested with model and experimental data. The …

Retrospective Evaluation Of The Effects Of Human Disturbance And Goldfish Introduction On Endangered Pahrump Poolfish, James E. Deacon, Joshua E. Williams

Western North American Naturalist

Life history data for Pahrump poolfish (Empetrichthys latos latos) collected from 1937 to 1975 were organized and analyzed to improve our understanding of changes caused by human habitat disruption and introduced goldfish (Carassius auratus) at Manse Spring, Nevada. Pahrump poolfish twice demonstrated their ability to recover numerically from a population crash. The first crash followed a November 1961 introduction of a few goldfish and subsequent removal of vegetation by local ranch children intent on turning Manse Spring into a swimming hole. The second crash followed another major habitat disturbance resulting from an unsuccessful attempt to eradicate …

Considerations For Wood River Sculpin Conservation: Historical Occurrence And Sampling Efficiency, Donald W. Zaroban

Western North American Naturalist

Records of Wood River sculpin (Cottus leiopomus) from 1893 to 2003 were examined and new data were gathered in 2004 and 2006 to estimate the species’ historical range and to search for evidence of changes in its occurrence. Detections of Wood River sculpin were reported in 49 subwatersheds, primarily in the Idaho Batholith ecoregion. The remainder of the Wood River basin was classified as either potential historic range or unknown. Mark-recapture sampling was conducted to estimate the efficiency of electrofishing as a method to detect this sculpin. Sampling efficiency was calculated for 1 upstream pass and 1, 2, …

Mate Sampling In A Natural Population Of Pecos Gambusia, Gambusia Nobilis, John K. Leiser, Kimberly Little, Murray Itzkowitz

Western North American Naturalist

Much research has been conducted on the mating systems of poeciliid fish in aquaria; however, there are fewer studies that examine mate sampling of these fish in the wild. In general, male poeciliids are characterized as being unselective in their mate choices and will attempt to copulate with seemingly all available females. Females are selective, copulate infrequently, and are often pursued by “ardent” males who may force copulations. To avoid male harassment, females in aquaria will often shelter from males among other females in shoals. Here, we examined the mate-sampling behaviors of male and female Pecos gambusia Gambusia nobilis by …

Fecal Pellets Of American Pikas (Ochotona Princeps) Provide A Crude Chronometer For Dating Patch Occupancy, Lyle B. Nichols

Western North American Naturalist

American pikas (Ochotona princeps) seem to be especially vulnerable to climate change, with recent extinctions of pika populations being attributed to global warming. Incomplete historical location records are currently used to examine changes in pika distributions. A method of determining recent pika distributions in the absence of historical records is needed. Here I report on changes over time of known-age pika fecal pellets up to 36 years old. Predictable changes in diameter, internal consistency, and color of pellets provide a method to approximate the dates of last occupation in patches where pikas have been extirpated.

Diversity, Phenology, And Elevational Distribution Of Ephemeroptera, Plecoptera, And Trichoptera In American Fork Canyon, Utah, Sarah Walker Judson, C. Riley Nelson

Western North American Naturalist

Although the aquatic insect fauna of Utah and their associated adult forms are well documented taxonomically and biogeographically, little is known about seasonal and elevational patterns of aquatic insect diversity in individual Wasatch streams. We selected the American Fork River, a relatively pristine stream with little anthropogenic disturbance, as our target stream to investigate elevational distribution and seasonal phenology of adult forms of Ephemeroptera, Plecoptera, and Trichoptera (EPT). From April to October in 2003 through 2005, a total of 71 adult forms of EPT species were documented along the American Fork River. No single sampling period captured more than 30 …

The Stream–Lake Ecotone: Potential Habitat For Juvenile Endangered June Suckers (Chasmistes Liorus), Russell B. Rader, Mark C. Belk, Rollin Hotchkiss, Jaron Brown

Western North American Naturalist

Potamodromous fish are poorly studied even though they are threatened often by human activities. The June sucker (Chasmistes liorus) is an endangered potamodromous species endemic to Utah Lake. Larval June suckers have not been collected from Utah Lake for at least 3 decades. Recruitment appears to be limited by low temperatures and scarce food, resulting in mass starvation of larval June suckers in the stream environment. We compared water temperature, zooplankton food availability, and small fish abundance in the stream and in 3 habitats along the stream–lake ecotone (dense emergent vegetation, sparse emergent vegetation, and open lake) to …

The Banner-Tailed Kangaroo Rat, Dipodomys Spectabilis (Rodentia: Heteromyidae), In Utah, George V. Oliver, Anthony L. Wright

Western North American Naturalist

We report the discovery in Utah of Dipodomys spectabilis, a species previously unknown to occur in the state. We searched for D. spectabilis in extreme southeastern Utah, south of the San Juan River, and were successful in finding mounds and burrows characteristic of the species and in capturing one individual. This is the northernmost record for D. spectabilis and extends its known range ~84 km northwest of the nearest previously reported locality (Fruitland, San Juan County, New Mexico). A flea, Meringis rectus, collected from D. spectabilis, is also the first record of its species in Utah.

Brown-Headed Cowbird Parasitism On Endangered Species: Relationships With Neighboring Avian Species, Shannon L. Farrell, Michael L. Morrison, R. Neal Wilkins, R. Douglas Slack, Andrew J. Campomizzi

Western North American Naturalist

Loss of reproductive productivity in hosts of the Brown-headed Cowbird (Molothrus ater), a nest parasite, may limit the success of conservation and recovery efforts that focus on restoring avian habitat. We investigated the relationships between parasitism frequency of 2 vireos—the endangered Black-capped Vireo (Vireo atricapillus) and the White-eyed Vireo (Vireo griseus)—and characteristics of the neighboring avian assemblage. Our objective was to identify assemblage characteristics that are useful for predicting parasitism frequency. We hypothesized that parasitism frequency of the vireos would decrease with increasing alternate host abundance and increase with increasing abundance of cowbirds. All …

Distribution Of A Unique Limpet (Gastropoda: Ancylidae) In The Colorado River Drainage Basin, Western North America, Peter Hovingh

Western North American Naturalist

I determined the distribution of limpets (Gastropoda: Ancylidae: Ferrissia) in the Colorado River and Rio Grande basins by handpicking specimens from the undersides of rocks and vegetation at 16 sites from a total of 495 surveyed sites in Colorado, Utah, New Mexico, and Arizona. Shell morphology, including morphometrics, was compared to species holotype descriptions and museum lots. Ferrissia rivularis occurred in the upper Colorado, Gunnison, and San Juan rivers, and in the upper Rio Grande basin.Ferrissia walkeri, hereafter called the Walker morph, occurred only in the Gila River basin of Arizona and New Mexico. I reviewed the problems …
