Amphibian Occupancy And Functional Connectivity Of Restored Wetlands In The Missouri River Floodplain, Michelle L. Hellman
Dissertations & Theses in Natural Resources
Wetland decline may threaten many taxa including shorebirds, amphibians, and fish. As agencies increase restoration of wetland habitat, monitoring is crucial to inform the process. Permeable skin sensitive to water quality and biphasic life histories requiring both terrestrial and aquatic habitat make amphibians good indicators of wetland health. I modeled amphibian occupancy in restored Missouri River bends to determine habitat characteristics associated with the presence of amphibians.
Occupancy modeling acknowledges imperfect detection and allows the inclusion of detection covariates. To assess detection I examined two methods currently used to assess anuran occupancy in wetlands, aural anuran surveys and tadpole dip-netting ...

Flash4 Dark Reference Images, George Mcnamara
Hamamatsu FLASH4.0 dark reference images, acquired with 10 second exposure times, no light to camera. Camera offset (set by Hamamatsu( is ~100 (the average intensity of the first image is always ~1 intensity level higher - an odd feature, but trivial in practice for a 16-bit camera).

Video Codec Performance (Excel Spreadsheet), George Mcnamara
Video codec performance (Excel spreadsheet). Movie was made in 2005-2006 when I worked at City of Hope National Medical Center. VTLF refers to Video Timelapse Light Facility. Videos were outputted from MetaMorph as AVI files. Personally, I always recommend uncompressed video files fro scientific uses. I also encourage posting the original scientific data format (ex. .lsm, .zvi, .lif, .stk).

Tattletales is my concept for spatial multiplexing many fluorescent protein (FP) biosensors in the same live cell. For example, there are excellent FP biosensors to Ca++ ions, pH, glucose, ribose, glutamine, glutamate, ATP, redox, ROS, pyruvate, cAMP, cGMP, IP3, PI(3,4,5)P3, cell cycle indicators (Fucci2), PKA, PKC, photsphatases, caspase(s) [1, 2]. However, these are typically used one biosensor per experiment, due in part to flooding the cell with soluble biosensor. That is, conventionally, either a metabolite (glucose) reporter or a signal transduction (Ca++) reporter can be imaged. By flooding the cell with the reporter, signal to noise ratio is compromized by autofluorescence.
Tattletales takes advantage of spatial multiplexing to both increase the number of different reporters, and improve signal to noise ratio by localizing each biosensor to a small volume. I started with the observation by Robinett et al  who localized 512 GFP-nls-LacI to a 256 LacO array as a 200 nm diameter diffraction limited spot (nuclear background due to overexpression). Many thousands of DNA binding proteins, of known sequence specifities, exist (LacI, TetR, GalR, etc for cell line studies; ZF-FPs, TALE-FPs to STRs, telomere repeat binding factors-FPs, etc for primary cells) and can be fused (as cDNAs) to different fluorescent proteins and FP biosensors.
Many biosensors are available as affinity series [1, 4], now enabling extended dynamic range. I realized that spatial multiplexing of many DNA binding protein-reporters by localizing to different spots in the cell nucleus and distinguished by combinatorial addressing, where N address colors ...

Are We Seeking Pimatisiwin Or Creating Pomewin? Implications For Water Policy, Patti Laboucane-Benson, Ginger Gibson, Allen Benson, Greg Miller
The International Indigenous Policy Journal
The purpose of this discussion is to describe the worldview and sacred relationship of the Cree people in Alberta, as well as how colonial policy has created despair (pomewin) in Aboriginal communities and a state of disconnectedness from the water. It concludes with the presentation of a framework for the development of policies that seek to repair the relationship between Aboriginal people and mainstream society – with the potential to create the good life, broadly defined (pimatisiwin) for all Albertans (Aboriginal and non-Aboriginal). This discussion is based upon the findings of a three-year research project entitled “The Sacred Relationship”. The goals ...

Advanced Structural And Functional Magnetic Resonance Imaging In Chronic Low Back Pa, Gavin Jones
Open Access Dissertations and Theses
An objective measure of muscular low back pain (LBP) symptoms eludes clinicians. This study assessed efficacy of magnetic resonance imaging (MRI) of the lumbar multifidus using diffusion tensor imaging (DTI), blood oxygen level dependent (BOLD) signal fractal dimension (FD) analysis and muscle cross sectional area (CSA) in LBP assessment. MRI results were compared to two questionnaires, the Oswestry disability index (ODI) and visual analog score (VAS).
Right-left asymmetry in both DTI metrics and T2-weighted (T2W) CSA were greater in the injured. Also, asymmetry measures were correlated with body mass index (BMI) but not age, height, or level of physical activity ...

“The Power Of The Author Of Nature”: An Exploration Of John Woodward’S Fusion Of Natural And Revealed Religion, Christine Bugler
Open Access Dissertations and Theses
Sir Isaac Newton’s famous discovery of gravity marks the rapid advancement of science in the English seventeenth century, and a permanent shift away from the scientific methods of antiquity. Natural philosophers were beginning to look at the physical world in new and dynamic ways. However, much of this new theory conflicted with traditional theology, which was problematic for Christian followers of this ‘new science’. To negotiate this conflict, a group of natural philosophers developed a new branch of science entitled physico-theology. This stream aims to prove that science does not dismiss religion, but is able to reinforce the existence ...

Cosmic Ray Particles Images With Orca-Ii Erg, George McNamara University of Miami
Cosmic Ray Particles Images With Orca-Ii Erg, George Mcnamara
Cosmic ray particles image series acquired using a Hamamatsu ORCA-II ERG scientific grade CCD camera, cooled to -60 C. Each image is a consecutive 600 second (10 minute) exposure time with no light to the camera.
While processing the data, I discoverd that the background changed around planes 25 and 227 (see Excel file and jpeg screenshots), so I also processed only planes 025-227 (203 planes total, 2030 minutes, 33.83 hours). the CCD industry "rule of thumb" for a "typical" CCD sensor (i.e. 1/3" CCD) is that one cosmic ray particle strikes a sensor approximately every 30 ...

A Pilot Study: The Use Of A Survey To Assess The Food Knowledge Of Nutrition Students At Various Levels Of Nutrition Education, Chante Chambers
Open Access Theses and Dissertations from the College of Education and Human Sciences
A working definition of a concept known as ‘food literacy’ encompasses using basic food preparation knowledge that has been learned, understood, and practiced to make better food decisions. To advance these skills for client service, a post-secondary nutrition program would need to include objectives that allow application of knowledge. For this reason, the purpose of this study was to determine the difference in knowledge and application among students in 100, 200 and 400 level college nutrition course(s). A survey was developed to measure the food knowledge of these college students as they prepare for careers as health care professionals ...
