Effects Of Three Emulsion Compositions On Taste Thresholds And Intensity Ratings Of Five Taste Compounds, J. E. Thurgood, Silvana Martini
Effects Of Three Emulsion Compositions On Taste Thresholds And Intensity Ratings Of Five Taste Compounds, J. E. Thurgood, Silvana Martini
Nutrition, Dietetics, and Food Sciences Faculty Publications
This study assessed the effects of three emulsified systems on taste thresholds and the near-threshold taste intensities of the five tastes (sweet, sour, salty, bitter and umami). Emulsions were formulated with different lipid chemical compositions. Lipid addition in an emulsified form significantly increased thresholds for sour and bitter tastes produced by citric acid and quinine hydrochloride, respectively. No significant differences were found in the threshold levels in emulsions formulated with different lipids for the five tastes evaluated. In general, for the same tastant concentration, taste intensities for sour and bitter tastes were lower in emulsions compared with the aqueous solutions, …

Poor instruction has been cited as a primary cause of attrition from STEM majors and a major obstacle to learning for those who stay [Seymour and Hewitt [1997]. Talking about leaving: Why undergraduates leave the sciences. Boulder, CO: Westview]. Using a double-blind design, this study tests the hypothesis that the lack of explicit instructions in scientific inquiry skills is a major factor in both low STEM retention and academic underperformance. This project delivered supplemental instruction to students in a laboratory-based undergraduate biology course (n = 314) that was derived either from cognitive task analyses (CTAs) conducted with expert biologists (treatment) …

Back Where They Once Belonged? Local Response To Afforestation In County Kerry, Ireland, Matthew S. Carroll, Áine Ní Dhubháin, Courtney G. Flint
Back Where They Once Belonged? Local Response To Afforestation In County Kerry, Ireland, Matthew S. Carroll, Áine Ní Dhubháin, Courtney G. Flint
Sociology, Social Work and Anthropology Faculty Publications
Afforestation has many benefits at the local regional and global scale. The local social impacts of planting new forests, however, depend on a variety of contextual factors and other details including who is doing the planting, which species are being planted, the location of the planting and, perhaps most importantly, existing land uses and their linkage to social and economic circumstances. This article presents case study research into these issues in two places in County Kerry Ireland. Utilising the concept of the differentiated landscape, we examine the somewhat varying social responses to afforestation in the two study sites in light …

Newquist suggests that students' publications are important predictors of post-degree research effectiveness, due in part to the importance of collaboration in innovative research. We agree that publication record is important and helpful, but the collaborative aspects of writing render publications a noisy metric by which to assess individual growth on specific skills (1). The variable time lags between the execution of an experiment, analysis of its data, and publication of findings [e.g., (2)] further limit the ability to identify direct relationships between experiences in a doctoral program and scholarly growth. Doctoral education's overarching goal is to develop competent researchers capable …

A Call For Performance-Based Data In The Study Of Stem Ph.D. Education, David F. Feldon, Michelle A. Maher, Briana E. Timmerman
Instructional Technology and Learning Sciences Faculty Publications
Understanding the scholarly development of Ph.D. students in science, technology, engineering, and mathematics (STEM) is vital to the preparation of the scientific workforce. During doctoral study, students learn to be professional scientists and acquire the competencies to succeed in those roles. However, this complex process is not well studied. Research to date suffers from overreliance on a narrow range of methods that cannot provide data appropriate for addressing questions of causality or effectiveness of specific practices in doctoral education. We advocate a shift in focus from student and instructor self-report toward the use of actual performance data as a remedy …

Why Magic Bullets Don't Work, David F. Feldon
Instructional Technology and Learning Sciences Faculty Publications
We always tell our students that there are no shortcuts, that important ideas are nuanced, and that recognizing subtle distinctions is an essential critical-thinking skill. Mastery of a discipline, we know, requires careful study and necessarily slow, evolutionary changes in perspective. Then we look around for the latest promising trend in teaching and jump in with both feet, expecting it to transform our students, our courses, and our outcomes. Alternatively, we sniff disdainfully at the current educational fad and proudly stand by the instructional traditions of our disciplines or institutions, secure in our knowledge that the “tried and true” has …
Measuring Relationships Between Camp Staff And Camper Developmental Outcomes: An Application Of Self-Determination Theory, Mark F. Roark, Gary D. Elis, Mary Sara Wells, Ann Gillard
Measuring Relationships Between Camp Staff And Camper Developmental Outcomes: An Application Of Self-Determination Theory, Mark F. Roark, Gary D. Elis, Mary Sara Wells, Ann Gillard
Kinesiology and Health Science Faculty Publications
While recent studies have suggested that positive developmental outcomes may result from participating in camp experiences, it is unclear what specific aspects of camp (e.g., staff dispositions, counselor teams, non-counselor staff) might influence these camper outcomes. Previous studies have measured the autonomy support of schoolteachers and found that more autonomy-supportive dispositions that, for example, engage autonomy, relatedness, and competence through the use of meaningful choice or rationale have positive effects on student developmental outcomes (e.g., intrinsic motivation, competence, self-esteem). Unlike schools, camps are noncompulsory recreation environments and most are outdoor-based. The existence of differences between the physical, social, and motivational …
Do Psychology Researchers Tell It Like It Is? A Microgenetic Analysis Of Research Strategies And Self-Report Accuracy, David F. Feldon
Do Psychology Researchers Tell It Like It Is? A Microgenetic Analysis Of Research Strategies And Self-Report Accuracy, David F. Feldon
Instructional Technology and Learning Sciences Faculty Publications
Acquiring research skills is considered to be a highly challenging aspect of developing expertise in the social sciences. Because instruction and mentoring in these skills are typically grounded in the self-report of researchers, difficulties in learning the material may be due to the content and accuracy of these explanations. Using a mixed-method, microgenetic design, this study examines the explanations of problem-solving processes by researchers along a continuum of expertise during simulated experiment design and subsequent data analysis. Findings indicate that participants’ self-explanations are largely inaccurate. Further, frequency of inaccurate statements is positively associated with the frequency of abstract cognitive processes, …

Food Habits Of Wintering Waterfowl On The Great Salt Lake, Utah, Josh L. Vest, Michael R. Conover
Food Habits Of Wintering Waterfowl On The Great Salt Lake, Utah, Josh L. Vest, Michael R. Conover
Wildland Resources Faculty Publications
Two invertebrates, brine shrimp (Artemia franciscana) and brine flies (Ephydridac), occur in great densities in the Great Salt Lake (GSL) but it is unknown whether ducks forage extensively on them during winter or rely on freshwater food. Common Goldeneye (Bucephala clangula), Northern Shoveler (Anas clypeala) and Green-winged Teal (Anas crecca) were collected from the GSL during winters 2004–05 and 2005–06 to evaluate their food habits. Brine shrimp and brine flies comprised more than 70% of the winter diet of these ducks. Common Goldeneyes consumed mainly brine fly larvae (68% based on dry weight biomass), which live primarily along the substrate. …

Altering Functional Properties Of Fats Using Power Ultrasound, A. H. Suzuki, J. Lee, S. G. Padilla, Silvana Martini
Nutrition, Dietetics, and Food Sciences Faculty Publications
Ultrasound has been used for the last 50 y in different processing applications. Depending on the power and frequency of the sound waves, ultrasound techniques can be classified in different categories. Low-intensity ultrasound uses high frequencies in the range of 100 kHz to 10 MHz and is mostly used for therapeutic purpose (frequencies between 1 and 10 MHz) and to passively monitor the characteristics of materials (frequencies between 100 kHz and 10 MHz). High-intensity ultrasound (HIU), on the other hand, uses lower frequencies in the range of 20 to 100 kHz and it is commonly used for cleaning, disrupting, and …

A Passive Sampler For Ambient Gaseous Oxidized Mercury Concentrations, Seth N. Lyman, Mae Sexauer Gustin, Eric M. Prestbo
A Passive Sampler For Ambient Gaseous Oxidized Mercury Concentrations, Seth N. Lyman, Mae Sexauer Gustin, Eric M. Prestbo
USU Uintah Basin Faculty Publications
This paper reports on the development of a passive sampler for estimating gaseous oxidized mercury concentrations. Atmospheric gaseous oxidized mercury concentrations calculated from passive sampler data were correlated with those obtained using an automated analyzer (r2 = 0.71, p < 0.01, n = 110 for one-week deployments; r2 = 0.89, p < 0.01, n = 22 for two-week deployments). Sampler uptake was not significantly affected by changes in temperature, humidity, or ozone concentration, but it was slightly dependent on wind speed. As such, an equation for correcting data due to this factor was developed based on wind tunnel and field data. The detection limit for a two-week sampler deployment was ∼5 pg m−3. Field data collected in Nevada and the southeastern United States showed these samplers are useful for investigating spatial and temporal variability in gaseous oxidized mercury concentrations.

The State of Utah has one of the highest food insecurity rates in the nation. It is ranked in the top 4% in the nation of being food insecure and 34% of the state is considered low-income, defined as at or below 185% of poverty level (LeBlanc, Christofferson, & Christensen, 2008). These trends place Utah’s low-income population at increased risk of obesity and chronic disease. The Center of Hunger and Poverty reported a high rate of obesity among low-income individuals, with hunger, poverty, and obesity frequently occurring at the same time (USDA, 2009). With limited income, quantity is often more …

Investigating The “Why” In Whypox: Explorations Of A Virtual Epidemic, Yasmin B. Kafai, Maria Quintero, David F. Feldon
Instructional Technology and Learning Sciences Faculty Publications
Learning scientists have created and used virtual worlds to support players’ historical, scientific, and ecological inquiries. Much less explored has been the impact of community events on players’ investigations in virtual worlds. The authors present here the case of a community event Whypox, a virtual epidemic whose annual outbreak in Whyville affects players’ communication and appearance. The authors analyze the different levels of participation ranging from casual to systematic in which players searched out more information about the Whypox, participated in online discussions about its causes and investigated different scenarios with simulations. The discussion examines ethical concerns, the contributions of …

Playful Experiences: Measure Youth Outcomes In Parks And Recreation, Mark F. Roark, F. Evans
Kinesiology and Health Science Faculty Publications
Do you like to play or know anyone else who likes to play? Play has forever been a seminal focus for recreation and parks programs. When designing and implementing experiences for youth participants, we typically measure our success by how much fun youth had. These days, while play and the outcome of fun are still meaningful to youth, stakeholders expect outcomes beyond fun. From season to season, many of us now hear parent voices asking, “What will my children gain from your program?” or “Why is yours better? What makes yours unique?” City council members ask us to justify the …

An Application Of A Modified Experiential Learning Model For A Higher Education Course: Evidence Of Increased Outcomes, Mark F. Roark, Jonathan C. Norling
Kinesiology and Health Science Faculty Publications
This case study applied a modified Experiential Learning Theory (ELT) model in an undergraduate outdoor recreation management course. The Kolb (1984) ELT model was modified to accommodate the higher education learning processes suggested by L. B. Sharp (1943), Sugarman (1985) and Greenaway (1995). Results indicate evidence of increased student learning. Quantitative results from a retrospective pre/posttest evaluation of change score means in learning outcomes supported the study hypotheses that 1) the application of a modified ELT model affects the outcomes of planning, knowledge/skills, and potential for transfer of learning and 2) previous trip experience affects these outcomes. A secondary analysis …

Existing literature provides insight into the nature and extent of plagiarism amongst undergraduate students (e.g., Ellery, 2008; Parameswaran & Devi, 2006; Selwyn, 2008). Plagiarism amongst graduate students is relatively unstudied, however, and the existing data are largely based on self-reports. This study investigated the rates and potential causes of plagiarism amongst graduate students in master’s and doctoral programmes in science, technology, engineering, mathematics, and science or mathematics education by examining actual research proposals written by graduate students. Results indicate that plagiarism is a prevalent issue at each of the three university sites sampled and across all of the investigated disciplines. …
Flying Squirrel Removal Does Not Reduce Their Use Of Simulated Red-Cockaded Woodpecker Nest Cluster, Jennifer S. Borgo, Michael R. Conover, L. Michael Conner
Flying Squirrel Removal Does Not Reduce Their Use Of Simulated Red-Cockaded Woodpecker Nest Cluster, Jennifer S. Borgo, Michael R. Conover, L. Michael Conner
Wildland Resources Faculty Publications
Reproductive success of the endangered Picoides borealis (Red-cockaded Woodpecker) is thought to be reduced by the presence of Glaucomys volans (Southern Flying Squirrels); hence, these squirrels are often removed when found inside woodpecker cavities. For this management practice to benefit Red-cockaded Woodpeckers, however, squirrel removal must both reduce the future probability of a flying squirrel re-occupying cavities and increase reproductive success for Red-cockaded Woodpeckers. In this study, using simulated Red-cockaded Woodpecker clusters (pseudo-clusters), we tested the first assumption regarding squirrels reoccupying nest cavities. We found no differences between removal and control pseudo-clusters in the amount of time that flying squirrels …
