MANOVA modelling of a chiropractic longitudinal study using multiple imputation
No full textThe purpose of this report is to present the detailed statistical analysis of a randomised, placebo-controlled trial comparing two different treatment modalities to an intervention of no known benefit for people with acute or subacute thoracic spine pain.
The therapy arms consist of Spinal Manipulative Therapy (SMT) and Graston Technique (GT) and the placebo is a non-functional ultrasound. A placebo group was utilised because at present there are no proven treatments for non-specific thoracic pain. This trial is registered with the Australia and New Zealand Clinical Trials Registry. Ethics approval has been granted by Murdoch University Human Research and Ethics Committee, number 2007/274.
The aim of this three arm trial was to test the efficacy of SMT and GT as independent modalities compared to detuned ultrasound for the outcomes of pain and disability. The latter were measured using the Visual Analogue Scale (VAS) and a modified Oswestry Back Pain Disability Index. The study was conducted at the Murdoch University Chiropractic student clinic in Perth, Australia, and the protocol published in Crothers et al (2008).
In this report, Section 2 provides an initial exploratory analysis of the data, Section 3 outlines the statistical models used in the final analysis, Section 4 defines these models in mathematical terms, Section 5 discusses the management of missing values via multiple imputation and Section 6 presents the results of the statistical modelling and hypothesis tests. The clinical study will be published in full elsewhere

What's the gang wearing?: An exploratory and descriptive analysis of police gang uniforms
No full textPrevious studies on police uniforms have found uniform color and style continue to evolve as do the dynamics around police uniforms and citizen impression. Given no research has been done specifically on police gang unit uniforms, this study was exploratory and aimed to determine if there was a visual standard regarding the operational appearance of police gang unit uniforms in Canada and the United States. Using targeted and purposive sampling the researcher collected 64 samples of digital images containing police gang unit officers in uniform for content analysis. The analyzed data yielded quantitative statistics that were applied to the primary research question. These statistics found that police gang unit officers in Canada and the United States are most likely to deploy in a unit-specific police uniform, that is black in color, visually identifies as a gang unit (by patch or crest), and be wearing external body armor that is black in color. The researcher suggests the study’s findings be applied to further research to determine the potential implications police gang crime unit uniforms may have on citizen impression. All of which contributes to the ongoing debates around the militarization of the police.social constructionpolice gang unitgangsuniformpolice uniformuniform colormilitarizationArticle based on honours thesis by Colton Lazarowic
Colton Formation (Eocene: Fluviatile) and Associated Lacustrine Beds, Gunnison Plateau, Central Utah
No full textAuthor Institution: Department of Geology, The Ohio State University, Columbus, Ohio 43210The Colton Formation consists mostly of fluvial (floodplain and channel) deposits that are less resistant and more highly colored than the adjacent lacustrine beds of the Flagstaff and Green River Formations. The contrast between the fluviatile and lacustrine strata is indicated by several lithic and faunal characteristics that occur in a short stratigraphic interval, and that permit precise and regionally persistent recognition of the limits of the Colton Formation. The Colton is distinguished by: 1) red, yellow, or brown, fine- to medium-grained, micaceous, feldspathic subangular sandstones that are crossbedded, thick-bedded, laterally non-persistent, and typically lens-shaped in cross-section; 2) red, green, or purple, somewhat silty or sandy mudrocks and shales that are poorly fossiliferous and poorly bedded; 3) limestone beds, locally of pastel colors, that are generally less than 1 foot thick, non-persistent, tough, platy and poorly fossiliferous; 4) far fewer fossil snails and clams than the regionally continuous carbonate units of the middle and upper Flagstaff Formation.
In contrast, lacustrine beds that bound the Colton Formation are characterized by the following features; 1) pale grey, fine-grained, subrounded sandstones, without crossbedding, that are rather thin and widespread (Flagstaff only); 2) yellow-brown or gray, thin-bedded, tough and platy limy shales that are fossiliferous and interbedded with limestone and dolomite units; 3) limestones and dolomites of several petrographic types that are two feet thick or more, and laterally persistent.
When distinguished by the sum of these characteristics, the Colton consists in the central Gunnison Plateau of a northward-thinning wedge. From a thickness of 800 feet at South Maple Canyon, it thins to less that 550 feet at Wales Canyon, north of which it has been removed by erosion. The formation becomes much more clastic toward the north in the area studied
We Must Grow Our Own Artists: Mary-Russell Ferrell Colton, Northern Arizona\u27s Early Art Educator
No full textWhat were Mary-Russell Ferrell Colton’s contributions to the progressive education movement and the Indian arts and crafts movement in the Southwestern United States at a time when the region was still very remote? Artist, author, amateur ethnographer, educator, and curator; these were but a few of the talents of Mary-Russell Ferrell Colton, co-founder of the Museum of Northern Arizona and early art advocate on the Colorado Plateau. This study investigates how Colton contributed to the progressive education movement and the Indian arts and crafts movement through the work that she did at the museum. There, she labored to increase public awareness of the importance of art education and to revive Native American arts on the Colorado Plateau. Using an extensive collection of archival material in the Colton Collection at the Museum of Northern Arizona, as well as oral history interviews, this historical study provides a nuanced analysis of Colton’s life as an educator. Colton’s influence is not well known today, but her professional contributions merit recognition, giving her a place in the history of American education. This study reveals how Colton’s efforts fit within the context of the work of her contemporaries in Santa Fe and Taos, and within the progressive education movement, from the then relatively remote outpost of Flagstaff. Much can be learned from Colton’s work that is relevant to the field of education today. Her ideals and writings about art education will resonate with opponents of No Child Left Behind. Colton’s work as one of northern Arizona’s earliest art educators contributed to a better understanding of the culture of the various peoples of the Colorado Plateau and to the preservation of Navajo and Hopi traditions through education. Colton made notable contributions to the Indian arts and crafts movement, museum education, and the progressive education movement. A woman of firm convictions and ideals, Colton was strong-willed, and complex, a multi-faceted person with a broad range of interests which she pursued with passion and commitment. This study crosses the boundaries of several disciplines, including educational history, museum studies, women’s studies, educational biography, Native American studies, and art education
Islet Assessment for Transplantation
No full textAuthor Manuscript: 2010 December 1.Purpose of review:
There is a critical need for meaningful viability and potency assays that characterize islet preparations for release prior to clinical islet cell transplantation (ICT). Development, testing, and validation of such assays have been the subject of intense investigation for the past decade. These efforts are reviewed, highlighting the most recent results while focusing on the most promising assays.
Recent Findings:
Assays based on membrane integrity do not reflect true viability when applied to either intact islets or dispersed islet cells. Assays requiring disaggregation of intact islets into individual cells for assessment introduce additional problems of cell damage and loss. Assays evaluating mitochondrial function, specifically mitochondrial membrane potential, bioenergetic status, and cellular oxygen consumption rate (OCR), especially when conducted with intact islets, appear most promising in evaluating their quality prior to ICT. Prospective, quantitative assays based on measurements of OCR with intact islets have been developed, validated and their results correlated with transplant outcomes in the diabetic nude mouse bioassay.
Conclusion:
More sensitive and reliable islet viability and potency tests have been recently developed and tested. Those evaluating mitochondrial function are most promising, correlate with transplant outcomes in mice, and are currently being evaluated in the clinical setting.National Center for Research Resources (U.S.) (Grant)National Institutes of Health (U.S.) (Grant U42 RR 016598–01)National Institutes of Health (U.S.) (Grant RO1-DK063108–01A1)Iacocca FoundationSchott FoundationCarol Olson Memorial Diabetes Research Fun
Implementation of the eLearning lifecycle model to develop reflection in pre-service teachers
No full textThis paper outlines the planned research into the use of an ePortfolio Environment to support the development of reflection in pre-service teachers. Reflection is a key skill for teachers to possess as they continue to learn into the future. It is a doctoral research project that involves the implementation of sections of the eLearning Lifecycle model (Phillips, Kennedy, & McNaught, 2011) within a PebblePad platform. The proposed environment will include examples, activities and interactions as part of an Enculturation Teaching Model (Tishman, Jay, & Perkins, 1993). The impetus for the activities will be the sections of the Framework for Teacher Reflection (Colton & Sparks-Langer, 1993). The implementation aims to develop a teaching environment that can be used in a variety of platforms to develop reflective abilities in pre-service teachers that will be used for continued professional development
Assessing the interior British Columbia grasslands using the BIODESERT survey
No full textSummaryThe BIODESERT survey is a global cooperative study coordinated by Dr. Fernando Maestre, and assigned to me by Dr. Lauchlan Fraser. It was developed in order to study drylands worldwide to assess their proper functioning under the dry conditions caused by climate change, and damage caused by grazing. Many challenges arose leading to modification of the original methods, and the extension of my project to complete analysis and shipping of samples. In the Lac du Bois grasslands of Kamloops, I completed vegetation, grazing, and soil/IEM surveys to gather data and characteristics of plants species, grazers, and soil present. Furthermore, the tea-bag index was completed to assess general ecosystem activity. This work experience revealed much to me about this career path, and I highly recommend students try research through the UREAP or equivalent award. This project required much time and work to complete, but wasvery fulfilling and taught me many lessons that I will use moving forward.Not peer reviewe
