The question of whether there is or was life on Mars has been one of the most pivotal since Schiaparellis’ telescopic observations of the red planet. With the advent of the space age, this question can be addressed directly by exploring the surface of Mars and by bringing samples to Earth for analysis. The latter, however, is not free of problems. Life can be found virtually everywhere on Earth. Hence the potential for contaminating the Mars samples and compromising their scientiﬁc integrity is not negligible. Conversely, if life is present in samples from Mars, this may represent a potential source ...

Death Acceptance In Widowhood, 2014 University of Kentucky
Death Acceptance In Widowhood, Staci Ernsberger
Theses and Dissertations--Family Sciences
Death is a universal event that all living things experience. Older adults, in particular, are more mindful of death than younger generations because of their proximity and increased exposure to it. In addition, thoughts of one’s own death often increase with the death of a spouse. Previous research has explored the role of social support in death acceptance and the effect of previous marital satisfaction on a widow’s well-being. However, there is a lack of research regarding the experience of a widow’s personal death acceptance relative to spousal death acceptance and marital satisfaction. This phenomenological study aims ...
Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, 2013 Ancestral Health Society
Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, David B. Schwartz, Hamilton M. Stapell
Journal of Evolution and Health
Both academic and popular interest in the ancestral health movement, or “paleo” lifestyle, has grown rapidly in recent years. More people than ever are joining the movement, and more books and articles are being published on the topic. Media coverage and certain societal preconceptions of the movement have also increased. More often than not, followers of a paleo lifestyle are thought to be “modern cavemen”: athletic, single, meat-eating, young, white, and male. To test whether or not these stereotypes are true, the authors of the present study created the first large, academic survey (N = 3,967) of the ancestral health ...
Population Dynamics Of The Louisiana Black Bear In The Upper Atchafalaya River Basin, 2013 University of Tennessee, Knoxville
Population Dynamics Of The Louisiana Black Bear In The Upper Atchafalaya River Basin, Kaitlin Christine O'Connell
The Louisiana black bear (Ursus americanus luteolus) is listed as Threatened under the Endangered Species Act as a result of habitat loss and human-related mortality. Two of the 3 sub-populations must be viable for delisting to occur. I collected hair samples from 2010 to 2012 in a DNA mark-recapture study to augment data collected from 2007 to 2009 in the Upper Atchafalaya River Basin (UARB) to estimate abundance (N), growth rate (λ), and apparent survival rates (φ) to ultimately be used in a population viability analysis. In addition, I evaluated the effects of the opening of the Morganza Spillway in ...
Common Core 4th Grade Environmental Science Lesson Plans For California Teachers, 2013 California Polytechnic State University
Common Core 4th Grade Environmental Science Lesson Plans For California Teachers, Gillian Schoenfeld
Natural Resources Management and Environmental Sciences
This project and its analyses were conducted to assist California fourth grade elementary school teachers in adjusting to teaching Common Core standards and science curriculum in their classrooms. The project included the creation of lesson plans, which could be utilized throughout the state of California.
As the Common Core standards, California’s Next Generation Science Standards for K- 12, were just proposed in June of 2013, these lesson plans would help teachers update their lessons and provide them materials and concepts of how to do so. These lessons provide higher-order thinking for students, which is the whole concept of the ...

Case Study: The Parkinson's Experience, 2013 Western Oregon University
Case Study: The Parkinson's Experience, Scott A. Thurman
Previous research has extensively studied individual components of Parkinson’s by studying the disease but thus far does not address the comprehensive impacts and obstacles of life with Parkinson’s. The common experiences of Parkinson’s can offer insight as to how provide better care by addressing multiple domains in a person’s life. This hypothetical case study highlights commonalities shared by those with Parkinson’s that spans across social, emotional and biological aspects of life. Possible treatment strategies are discussed concerning the impacts of fatigue, social isolation, increased burdens of care, and family dynamics in order to offer insight ...
Amphibian Occupancy And Functional Connectivity Of Restored Wetlands In The Missouri River Floodplain, 2013 University of Nebraska - Lincoln
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 ...
Rutting Behavior And Factors Influencing Vehicle Collisions Of White-Tailed Deer In Middle Tennessee, 2013 University of Tennessee, Knoxville
Rutting Behavior And Factors Influencing Vehicle Collisions Of White-Tailed Deer In Middle Tennessee, Peyton Seth Basinger
White-tailed deer (Odocoileus virginianus; deer) and human populations have expanded, and as a result, deer-vehicle collisions (DVCs) have become a primary concern. In particular, Arnold Air Force Base (AAFB) in Tullahoma, Tennessee, USA has had extensive problems with DVCs and has struggled to incorporate effective mitigation strategies. To address this issue, I initiated a study on AAFB to investigate deer behavior and factors increasing the likelihood of DVCs.
DVCs typically increase with peaks in deer activity during the breeding season (rut). I deployed GPS-ARGOS satellite collars on 10 adult males and 10 females during the summer of 2010. I investigated ...
Governing Occupation Through Constructions Of Risk: The Case Of The Aging Driver, 2013 Western University
Governing Occupation Through Constructions Of Risk: The Case Of The Aging Driver, Silke Dennhardt
University of Western Ontario - Electronic Thesis and Dissertation Repository
Risk and risk-management have become increasingly pervasive features of modern society and governmentality scholars have highlighted various ways risk discourses are taken up to govern citizens and their everyday conduct. Thus, attending to risk is imperative to advance an understanding of how everyday occupation is shaped and governed within contemporary society. Within this study, the example of driving in later life is drawn upon to address two objectives: 1. to advance the understanding of how risk is taken up to govern everyday occupation, and 2. to explicate how risk is taken up in discourses to constitute particular subjectivities and their ...

Tattletales for Multiplex Fluorescent Reporters in Single Cells for Metabolomics
As of April 2013: L.J.N. Cooper & D.A. Lee Cellular Immunotherapy Lab, University of Texas M.D. Anderson Cancer Center, Houston, TX
Email: firstname.lastname@example.org, email@example.com
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 provide 2^N addresses (example, 3 colors is 2^3 = 8 combinations). Multiplexing ...

How Parental Divorce During Emerging Adulthood Gives Meaning To Women’S Experiences: A Phenomenological Approach, 2013 University of Kentucky
How Parental Divorce During Emerging Adulthood Gives Meaning To Women’S Experiences: A Phenomenological Approach, Kayla Reed
Theses and Dissertations--Family Sciences
This study examined how parental divorce impacts emerging adults’ familial relationships, romantic relationships, and development to build a basis for understanding emerging adult experiences. The participant sample consisted of 8 females between the ages of 19 and 24 (M = 21.6). A qualitative transcendental or psychological phenomenological research method was used. 90-minute interviews were conducted focusing on romantic relationships, family relationships, reactions and thoughts of parental divorce, and self-perception. NVIVO was used to allow a “bottom-up” design, emergent design, and interpretive inquiry for data analysis. Three themes emerged from the data: impacts of family dynamics, effects of developmental stage, and ...
Are We Seeking Pimatisiwin Or Creating Pomewin? Implications For Water Policy, 2012 Western University
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 ...
