Interest-Enhancing Approaches To Mathematics Curriculum Design: Illustrations And Personalization, Virginia Clinton, Candace Walkington

Educational Foundations and Research Faculty Publications

Two common interest-enhancement approaches in mathematics curriculum design are illustrations and personalization of problems to students’ interests. The objective of these experiments is to test a variety of illustrations and personalization approaches. In the illustrations experiment, students (n = 265) were randomly assigned to lessons with story problems containing decorative illustrations, contextual illustrations, diagrammatic illustrations, misleading illustrations, or no illustrations (only text [control condition]). Students’ problem-solving performance and attitudes were not affected by illustration condition, but learning was better in the control compared with contextual illustrations. In the personalization experiment, students (n = 223) were randomly assigned to …

Seasonal Home Ranges And Habitat Selection Of Three Elk (Cervus Elaphus) Herds In North Dakota, Jacqueline C. Amor, Robert Newman, William F. Jensen, Bradley Rundquist, W. David Walter, Jason R. Boulanger

Biology Faculty Publications

Changes in land use have resulted in range shifts of many wildlife species, including those entering novel environments, resulting in the critical need to understand their spatial ecology to inform ecosystem effects and management decisions. Dispersing elk (Cervus elaphus) were colonizing areas of suitable habitat in the Northern Great Plains, USA, resulting in crop depredation complaints in these areas. Although state resource managers had little information on these elk herds, limited evidence suggested temporal movements into Canada. We collected and analyzed essential information on home range and habitat selection for 3 elk herds residing in North Dakota. We …

Simultaneous High-Temperature Gas Chromatography With Flame Ionization And Mass Spectrometric Analysis Of Monocarboxylic Acids And Acylglycerols In Biofuels And Biofuel Intermediate Products, Gana Flanagan, Anastasia A. Andrianova, Jana Casey, Eric Hellrung, Bonnie A. Diep, Wayne Seames, Alena Kubatova

Chemistry Faculty Publications

Triacyl-, diacyl- and monoacylglycerols (TAGs, DAGs, MAGs) along with monocarboxylic acids (MCAs) are intermediate products in many triacylglycerol oil-to-biofuel conversion pathways. Accumulation of these compounds leads to poor biofuel characteristics and may result in fuel system damage. We developed a method for simultaneous identification and quantification of a wide range of MCAs (C4-C18), MAGs, DAGs, and TAGs. The method is based on trimethylsilylation followed by high temperature GC with programmed temperature vaporizer (PTV) injection coupled to parallel FID and MS detectors (HTGC-FID/MS).

To minimize the discrimination of both low and high molecular weight species typically occurring on the injector, we …

Investigating Graduate Education And Undergraduate Research Intentions Of College Science Students, Eric D. Deemer, Rachel L. Navarro, Angela M. Byars-Winston, Laura E. Jensen, Catherine P. Chen

Education, Health & Behavior Studies Faculty Publications

The current study examined predictors of undergraduate science students’ intentions to attend graduate school and participate in undergraduate research. We used social cognitive career theory to test our hypothesized model using a sample (N ¼ 411) of life science and physical science majors and examined basic interests in these disciplines as mediating variables. Among life science majors, results of structural equation modeling indicated that microbiology interest mediated the relationship between scientific self-efficacy (SSE) and graduate education intentions (GEIs) and the latter variable also mediated the relationship between microbiology interest and undergraduate research intentions (URIs). The model for physical science majors …

Ca2+ Entry Via Trpc1 Is Essential For Cellular Differentiation And Modulates Secretion Via The Snare Complex, Thad A. Rosenberger, Anne Schaar, Yuygang Sun, Pramod Sukumaran, Danielle Krout, James N. Roemmich, Lutz Brinbaumer, Kate Claycombe-Larson, Brij B. Singh

Biomedical Sciences Faculty Publications

Adipocyte functionality, including adipocyte differentiation and adipokine secretion, is essential in obesity-associated metabolic syndrome. Here, we provide evidence that Ca2+ influx in primary adipocytes, especially upon store-depletion, plays an important role in adipocyte differentiation, functionality, and subsequently metabolic regulation. The endogenous Ca2+ entry channel in both subcutaneous and visceral adipocytes was dependent on TRPC1-STIM1 and blocking Ca2+ entry with SKF-96365 or TRPC1-/- derived adipocytes inhibited adipocyte differentiation. Additionally, TRPC1-/- mice have decreased organ weight, but increased adipose deposition and reduced serum adiponectin and leptin concentrations, without affecting total adipokine expression. Mechanistically, TRPC1- mediated Ca2+ entry regulated SNARE complex formation and …

On The Interpretation Of The Normalization Constant In The Scaling Equation, Karl J. Niklas, Sean T. Hammond

Earth System Science and Policy Faculty Publications

The scaling equation, Y1 = βYα2, has been used empirically and explored theoretically primarily to determine the numerical value and meaning of the scaling exponent, α. The mathematical interpretation of α is clear—it is the quotient of the relative rate of change of Y1 with respect to the rate of change of Y2. In contrast, the interpretation of the normalization constant, β, is obscure, so much so that some workers have rejected the idea that it has any biological importance. With the notable exception of Steven J. Gould's early work, Huxley's dismissal of β largely relegated the study of its …

Integrated Management Of Invasive Cattails (Typha Spp.) For Wetland Habitat And Biofuel In The Northern Great Plains Of The United States And Canada: A Review, Dan Svedarsky, Richard Grosshans, Henry David Venema, Susan N. Ellis-Felege, J. Bruggman, Aaron Ostlund, Jeff Lewis

Biology Faculty Publications

On many public lands in the Great Plains region of the USA and Canada, cattail (Typha spp.) growth has far exceeded the 50:50 distribution recommended for optimum wetland wildlife habitat. Excessive cattail growth is the primary concern of wetland managers and its integrated management is reviewed here. The coverage of this mostly hybrid cattail (T. latifolia × T. angustifolia) is often over 90 % and if partially removed for habitat enhancement represents a substantial biomass resource in sites such as conservation wetlands, water retention basins and roadside drainage ditches. Available biomass is estimated to be 3,000 kg/ha assuming a 50 …

The Use Of Dehydroepiandrosterone For Treatment Of Depression, Bryan Tipton

Physician Assistant Scholarly Project Papers

Dehydroepiandrosterone (DHEA) and its sulfated ester (DHEA-S) are important pre-hormones that also have direct neurohormonal effects on the central nervous system. Over the last twenty years, data have revealed that serum DHEA peaks in a person’s mid-20s and steadily declines throughout their lifetime. In addition, women tend to have lower values than men. This is of note because lower serum values tend to be correlated with increased risk of depression, worse depressive symptoms, and increased risk of relapse into depression. A review of literature concerning DHEA’s age related values, its association with depression, and its use in the treatment of …

Barefoot Training: Effects On Emg Activity Of Gluteus Medius And Tensor Fascia Latae In Habitually Shod Runners, Tom Linner, Casey Murphy, Jeremy O'Keefe

Physical Therapy Scholarly Projects

Purpose/Hypothesis: Running has been a common practice in humans since the species’ dawn. Due to its relative ease and low cost, running continues to be one of the most popular forms of exercise today. Although running provides many benefits such as disease prevention, injury prevalence in running is high. The trend of minimalist shoes and barefoot training has gained popularity over the decade as a return to a more natural form of running. Some researcher hypothesize that barefoot running can reduce injury rate by changing the biomechanics of the runner. In this study we propose a different hypothesis: barefoot running …

Per- And Polyfluoroalkyl Substances In The Soil Environment: Sorption, Bioaccumulation And Biotransformation, Bosen Jin

Theses and Dissertations

Per- and polyfluoroalkyl substances (PFASs) are man-made chemicals, widely used in both industries and daily lives, such as in non-stick cookware, waterproof clothing, and painting materials. Researchers have investigated PFASs for about two decades, but most of the studies focus on perfluoroalkyl substances with very limited information available on polyfluoroalkyl substances. In this research, we investigated the sorption/desorption mechanisms perfluorooctanoic acid (PFOA) and its two cationic and zwitterionic precursor compounds, perfluorooctanesulfonamido ammonium salt (PFOSAmS) and perfluorooctaneamido betaine (PFOAB) in a group of soil. We also studied the bioaccumulation and bioconcentration of these chemicals along with perfluorooctane sulfonate (PFOS) and its …

Measuring Friendship Maintenance In Gay Men, Eliah Reding

Theses and Dissertations

This dissertation examines the existing friendship maintenance literature to develop a psychometrically sound scale for the measurement of friendship maintenance among gay men. Existing friendship maintenance research does not adequately capture the uniqueness of gay male friendship. Utilizing DeVellis’s (2016) steps of scale development, this dissertation constructs a new scale, the GayFABS, to assess the unique aspects of friendship maintenance in gay men. Unique in this dissertation is the use of a focus group to establish content validity rather than the traditional approach of expert review. An exploratory factor analysis is conducted to structure the scale and its component subscales. …

Influences Of Nesting Behaviors In Common Eiders (Somateria Mollissima Sedentaria) In The Western Hudson Bay, Tanner John Stechmann

Theses and Dissertations

Reproductive decisions of birds are shaped by minimizing predation while meeting physiological needs of parents and offspring. As a result, birds must make decisions about investment in offspring that allows them to maximize their overall fitness. This often drives nesting behaviors and can provide insights into reproductive success. Common eiders (Somateria mollissima) are thought to have high nest attendance (time spent tending the nest) and use substantial energetic resources during breeding. However, the specific behaviors at the nest of these birds are not well studied, with even less known about the Hudson Bay common eider (S. m. sedentaria). The objectives …
