The Influence Of Föhn Winds On Glacial Lake Washburn And Palaeotemperatures In The Mcmurdo Dry Valleys, Antarctica, During The Last Glacial Maximum, M. K. Obryk, P. T. Doran, E. D. Waddington, C. P. Mckay

Faculty Publications

© Antarctic Science Ltd 2017. Large glacial lakes, including Glacial Lake Washburn, were present in the McMurdo Dry Valleys, Antarctica, during the Last Glacial Maximum (LGM) despite a colder and drier climate. To address the mechanism capable of generating enough meltwater to sustain these large lakes, a conceptual model was developed based on the warming potential of infrequent contemporary föhn winds. The model suggests that föhn winds were capable of generating enough meltwater to sustain large glacial lakes during the LGM by increasing degree days above freezing (DDAF) and prolonging the melt season. A present-day relationship between infrequent summer föhn …

Hmgb1 Redox During Sepsis, Wasan Abdulmahdi, Devika Patel, May Rabadi, Tala Azar, Edson Jules, Mark Lipphardt, Rameen Hashemiyoon, Brian B. Ratliff

NYMC Faculty Publications

During sepsis, the alarmin HMGB1 is released from tissues and promotes systemic inflammation that results in multi-organ damage, with the kidney particularly susceptible to injury. The severity of inflammation and pro-damage signaling mediated by HMGB1 appears to be dependent on the alarmin's redox state. Therefore, we examined HMGB1 redox in kidney cells during sepsis. Using intravital microscopy, CellROX labeling of kidneys in live mice indicated increased ROS generation in the kidney perivascular endothelium and tubules during lipopolysaccharide (LPS)-induced sepsis. Subsequent CellROX and MitoSOX labeling of LPS-stressed endothelial and kidney proximal tubule cells demonstrated increased ROS generation in these cells as …

Bottom-Up Control Of Parasites, David S. Johnson, Richard W. Heard

Faculty Publications

Parasitism is a fundamental ecological interaction. Yet we understand relatively little about the ecological role of parasites compared to the role of free-living organisms. Bottom-up theory predicts that resource enhancement will increase the abundance and biomass of free-living organisms. Similarly, parasite abundance and biomass should increase in an ecosystem with resource enhancement. We tested this hypothesis in a landscape-level experiment in which salt marshes (60,000 m2 each) received elevated nutrient concentrations via flooding tidal waters for 11 yr to mimic eutrophication. Nutrient enrichment elevated the densities of the talitrid amphipod, Orchestia grillus, and the density and biomass of its trematode …

K-Bit-Swap: A New Operator For Real-Coded Evolutionary Algorithms, Aram Ter-Sarkisov, Stephen Marsland

Articles

There has been a variety of crossover operators proposed for Real-Coded Genetic Algorithms (RCGAs), which recombine values from the same location in pairs of strings. In this article we present a recombination operator for RC- GAs that selects the locations randomly in both parents, and compare it to mainstream crossover operators in a set of experiments on a range of standard multidimensional optimization problems and a clustering problem. We present two variants of the operator, either selecting both bits uniformly at random in the strings, or sampling the second bit from a normal distribution centered at the selected location in …

A Correlational Study: Personality Types And Foreign Language Acquisition In Undergraduate Students, Frank Capellan

Doctor of Education (Ed.D)

The purpose of this study was to investigate the relationship between personality types and second language acquisition. The study addressed a problem that is inadequately investigated in foreign language acquisition research; specifically, personality traits as predictors of language learning in college students studying Spanish as a foreign language. The researcher conducted one sample t-tests to assess statistically significant differences between mean personality type score and the test value, as well as, a multiple linear regression analysis. A convenient sample of college students (n=52) completed the Neris Personality Type Indicator at the beginning of the course, and took several examinations throughout …

Montine, Nilufer Ertekin-Taner, Matt R. Kaeberlein, Paul K. Crane

Biostatistics Faculty Publications

Introduction—We sought to determine whether a systems biology approach may identify novel late-onset Alzheimer's disease (LOAD) loci.

Methods—We performed gene-wide association analyses and integrated results with human protein-protein interaction data using network analyses. We performed functional validation on novel genes using a transgenic Caenorhabditis elegans Aβ proteotoxicity model and evaluated novel genes using brain expression data from people with LOAD and other neurodegenerative conditions.

Results—We identified 13 novel candidate LOAD genes outside chromosome 19. Of those, RNA interference knockdowns of the C. elegans orthologs of UBC, NDUFS3, EGR1, and ATP5H were associated with Aβ …

Psycho-Ecological Systems Model: A Systems Approach To Planning And Gauging The Community Impact Of Community-Engaged Scholarship, Roger N. Reeb, Nyssa L. Snow-Hill, Susan F. Folger, Anne L. Steel, Laura Stayton, Charles Hunt, Bernadette O’Koon, Zachary Glendening

Psychology Faculty Publications

This article presents the Psycho-Ecological Systems Model (PESM) – an integrative conceptual model rooted in General Systems Theory (GST). PESM was developed to inform and guide the development, implementation, and evaluation of transdisciplinary (and multilevel) community-engaged scholarship (e.g., a participatory community action research project undertaken by faculty that involves graduate and/or undergraduate students as service-learning research assistants). To set the stage, the first section critiques past conceptual models. Following a description of GST, the second section provides a comprehensive description of PESM, which represents an integration of three conceptual developments: the ecological systems model (Bronfenbrenner, 1979), the biopsychosocial model (Kiesler, …

Incorporation And Evaluation Of Authentic Research Experiences Into The Curriculum Through Development Of A Theory Of Action, Pamela Brown, Tammie Cumming, Joan D. Pasley

Publications and Research

A theory of action outlining undergraduate research program inputs and desired outcomes was developed and used to guide implementation of Course-Based Undergraduate Research Experience (CURE) sections and to create assessment tools to measure attainment of program goals in both apprentice-model undergraduate research and CURE. Student survey results for these two research programs were compared and suggest that many aspects of the academic goals such as designing an experiment, using equipment, collecting and analyzing data, and collaborating with others were achieved in both groups. Regarding the relationship with mentors, both groups reported receiving academic advisement in course selection and career options. …

Nudging Patient Decision-Making, Wendy Netter Epstein

Washington Law Review

Rational choice theory once pervaded the law. But we now know that individuals often make decisions that are not in their best interests. Many areas of the law have responded accordingly. The law of health care decision-making, however, has not. With limited exception, patients have the right to make their own medical decisions about their treatment, even if they make bad decisions. And there is ample evidence from the behavioral sciences that they do make bad decisions. Patients lack the stable preferences that the law assumes they will draw upon in making decisions, and they suffer from a number of …

Managing Opuntioid Cacti In Australia - Best Practice Control Manual For Austrocylindropuntia, Cylindropuntia And Optunia Species, M. R. Sheehan, S. Potter

Biosecurity published reports

The twenty-seven species of opuntioid cacti that are recognised as Weeds of National Significance are some of Australia's worst weeds. They grow over a wide climatic range and have impacted on pastoral and agricultural use of large tracts of land; pose an environmental risk to wildlife; and reduce aesthetic and recreational use, with direct impact on human safety.

Weedy infestations occur in all states and territories. Some are extensive, covering hundreds of thousands of hectares with a significant potential for range expansion

Over time there has been a substantial effort by government, industry, landholders and community groups to manage opuntioid …

The Trophic Life Cycle Stage Of The Opportunistic Fungal Pathogen Pneumocystis Murina Hinders The Ability Of Dendritic Cells To Stimulate Cd4+ T Cell Responses, Heather M. Evans, Andrew Simpson, Shu Shen, Arnold J. Stromberg, Carol L. Pickett, Beth A. Garvy

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The life cycle of the opportunistic fungal pathogen Pneumocystis murina consists of a trophic stage and an ascus-like cystic stage. Infection with the cyst stage induces proinflammatory immune responses, while trophic forms suppress the cytokine response to multiple pathogen-associated molecular patterns (PAMPs), including β-glucan. A targeted gene expression assay was used to evaluate the dendritic cell response following stimulation with trophic forms alone, with a normal mixture of trophic forms and cysts, or with β-glucan. We demonstrate that stimulation with trophic forms downregulated the expression of multiple genes normally associated with the response to infection, including genes encoding …

The Dual Role Of Group V Secretory Phospholipase A2 In Pancreatic Β-Cells, Preetha Shridas, Victoria P. Noffsinger, Andrea C. Trumbauer, Nancy R. Webb

Saha Cardiovascular Research Center Faculty Publications

Purpose

Group X (GX) and group V (GV) secretory phospholipase A₂ (sPLA₂) potently release arachidonic acid (AA) from the plasma membrane of intact cells. We previously demonstrated that GX sPLA₂ negatively regulates glucose-stimulated insulin secretion (GSIS) by a prostaglandin E2 (PGE2)-dependent mechanism. In this study we investigated whether GV sPLA₂ similarly regulates GSIS.

Methods

GSIS and pancreatic islet-size were assessed in wild-type (WT) and GV sPLA₂-knock out (GV KO) mice. GSIS was also assessed ex vivo in isolated islets and in vitro using MIN6 pancreatic beta cell lines with or without GV sPLA …

Characterization Of A Novel Mitochondrial Plasmid In Brassica, Mackenzie Strehle

UCARE: Research Products

Possessing some of the largest and most complex genomes of any eukaryotic organelles, plant mitochondria are notorious for their rapidly rearranging genetic framework. In addition to containing a large and complex mitochondrial genome, the mitochondria of several plants in the genus Brassica have also been shown to contain an independent, self-replicating linear plasmid. Interestingly, the plasmid appears to be able to move independently between the cytoplasm and the mitochondria, and it can be paternally inherited, unlike the rest of the mitochondrial genome. The plasmid also has features similar to those of adenoviruses, including terminal inverted repeats and covalently bound proteins …

Migratory Bird Conservation And Shellfish Aquaculture In Rhode Island: Legal Issues, Nicole Andrescavage

Sea Grant Law Fellow Publications

From 2014 to 2016, Rhode Island Shellfish growers applied for a series of leases to produce oysters in close proximity to lands used for waterfowl hunting. The emerging conflict between these uses required the relevant agencies to seek modifications to minimize problems and highlighted a need to better understand the relevant authorities governing these agencies. This study provides an overview of how state and federal legal authorities govern the interaction of shellfish leasing and waterfowl management in Rhode Island, including whether shellfish leasing may be considered incidental take under federal law.

Recognizing, Empathizing, And Strategizing Tools For Teachers And Schools To Increase Academic Success For Homeless Highly Mobile (Hhm) Students, Alyssa R. Paulson

School of Education and Leadership Student Capstone Projects

The homeless highly mobile (HHM) student population can easily be overlooked and begin to fall through the cracks within the school system. As a result, the achievement gap for this vulnerable population has grown at a disproportionate rate. Because of this, the author’s research question was: How can schools streamline academic success for homeless highly mobile (HHM) students? An examination of existing studies and literature demonstrates that the issue of the HHM student population having an achievement gap can be seen in schools across the country. However, research does show that there are strategies and resources for schools to implement, …
