The reading practices of young women and the production of gendered subjectivity
vi, 162 leaves ; 28 cm.Includes abstract.Includes bibliographical references (leaves 145-156).This thesis examines the possible connections between the reading practices of young women and the production of gendered subjectivities. It examines the relationship between the texts and readings of teen mystery-horror-romances by four women and the social contexts of these readers' lives. This study provides an analysis of a sample of the writings of Christopher Pike, interviews with four grade eleven women students, and this writer's pedagogy-in-practice surrounding readers and writers. Viewing reading practices through feminist post-structuralism provides an opportunity to identify reading, subjectivity, and pedagogy as cultural practices imbued with relations of power. Possibilities for transformation and disruption of these relations are the focus of this exploration of reading, texts, and subjectivities -- their construction, deconstruction, and reconstruction

Ray Casting Architectures for Volume Visualization
Real-time visualization of large volume datasets demands high performance computation, pushing the storage, processing, and data communication requirements to the limits of current technology. General purpose parallel processors have been used to visualize moderate size datasets at interactive frame rates; however, the cost and size of these supercomputers inhibits the widespread use for real-time visualization. This paper surveys several special purpose architectures that seek to render volumes at interactive rates. These specialized visualization accelerators have cost, performance, and size advantages over parallel processors. All architectures implement ray casting using parallel and pipelined hardware. We introduce a new metric that normalizes performance to compare these architectures. The architectures included in this survey are VOGUE, VIRIM, Array Based Ray Casting, EM-Cube, and VIZARD II. We also discuss future applications of special purpose accelerators.Engineering and Applied Science
Associations Between Australian Pseudoscorpions and Ants
The distribution of three species of pseudoscorpions, found
under the bark of blue gum Eucalyptus globulus, is closely correlated
with the presence of three species of ants. Marachernes bellus
is never found on trees without Anonychomyrma sp. near
foetens, and Protochelifer victorianus and Paraustrochernes victorianus are more commonly found on trees with Technomyrmex jocosus
and/or Tapinoma minutum. The distribution of another
pseudoscorpion, Conicochernes sp., is not influenced by the presence
of these ants. Observations of the behavior of these pseudoscorpions
indicate that at least some species may be specialist
predators of ants
Understanding Pregnant Women with Opioid Use Disorder
Background: Pregnant women with opioid use disorder are a major concern to the healthcare industry. They are not only one of the most stigmatized groups but are in need of outreach. Women who are afflicted by opioid addiction are a highly vulnerable group who are at risk of adverse pregnancy outcomes and perinatal complications. The purpose of this study was to do a meta-synthesis of the literature to gain a better understanding of the women’s perspective who are addicted to opioid during pregnancy.
Subjects and Method: We conducted an exhaustive literature search for qualitative studies that focused on women with opioid used disorder during pregnancy and postpartum. After conducting a rigorous methodological protocol for meta-synthesis described by Joanna Briggs Institute, ten studies met the criteria for inclusion into this study. We used the Qualitative Assessment and Review Instrument (QARI) from the Joanna Briggs Institute to assist with data management. We extracted the representative quotations and categorized them into like themes.
Results: There were three themes formulated from this meta-synthesis: overarching fear, trust, and educational deficits. This meta-synthesis of qualitative studies leads to a greater understanding of how pregnant women with opioid use disorder perceive the consequences of their actions.
Conclusion: Implications from this meta-synthesis will inform those working with opioid-addicted pregnant women and aid in establishing best practices for them and their infants by revealing their addiction experiences and narratives
An annotated list of the Lepidoptera of Honduras
A biodiversity inventory of the Lepidoptera of Pico Bonito National Park and vicinity, in the Department of Atlantida of northern Honduras, was initiated in 2009 to obtain baseline data. We present a revised checklist of Honduran butterfly species (updated from the initial 1967 lists), as well as the first comprehensive list of Honduran moths. Our updated list includes 550 species of Papilionoidea, 311 Hesperioidea, and 1,441 moth species

Phylogeographic structure and ecological niche modelling reveal signals of isolation and postglacial colonisation in the European stag beetle
Lucanus cervus (L.), the stag beetle, is a saproxylic beetle species distributed widely across Europe. Throughout its distribution the species has exhibited pronounced declines and is widely considered threatened. Conservation efforts may be hindered by the lack of population genetic data and understanding of the spatial scale of population connectivity. To address this knowledge gap this research details the first broad scale phylogeographic study of L. cervus based on mitochondrial DNA (mtDNA) sequencing and microsatellite analysis of samples collected from 121 localities across Europe. Genetic data were complemented by palaeo-distribution models of spatial occupancy during the Last Glacial Maximum to strengthen inferences of refugial areas. A salient feature of the mtDNA was the identification of two lineages. Lineage I was widespread across Europe while lineage II was confined to Greece. Microsatellites supported the differentiation of the Greek samples and alongside palaeo-distribution models indicated this area was a glacial refuge. The genetic endemism of the Greek samples, and demographic results compatible with no signatures of spatial expansion likely reflects restricted dispersal into and out of the area. Lineage I exhibited a shallow star like phylogeny compatible with rapid population expansion across Europe. Demographic analysis indicated such expansions occurred after the Last Glacial Maximum. Nuclear diversity and hindcast species distribution models indicated a central Italian refuge for lineage I. Palaeo-distribution modelling results also suggested a western refuge in northern Iberia and south-west France. In conclusion the results provide evidence of glacial divergence in stag beetle while also suggesting high, at least on evolutionary timescales, gene flow across most of Europe. The data also provide a neutral genetic framework against which patterns of phenotypic variation may be assessed.</div
