Oxygenation And Activation Of The Vastus Lateralis During Dynamic Constant External Resistance Leg Extension Muscle Actions In Older Women With And Without Sarcopenia, Brianna D. Mckay Aug 2019

Oxygenation And Activation Of The Vastus Lateralis During Dynamic Constant External Resistance Leg Extension Muscle Actions In Older Women With And Without Sarcopenia, Brianna D. Mckay

Public Access Theses and Dissertations from the College of Education and Human Sciences

The purpose of the present study was to compare muscle strength, size, activation, and oxygenation between older women with and without sarcopenia during dynamic fatiguing leg extension bouts with high (5-repetition maximum[5-RM]) and low (30% of estimated 1-RM[30%1-RM]) loads. Eleven women (n = 6 non-sarcopenic [mean ± SE; age = 75.8 ± 2.6y] and n = 5 sarcopenic [age = 74.5 ± 3.1y]) were screened for eligibility and sarcopenic status. Descriptive assessments including demographics (age, height, and weight), body composition by dual-energy x-ray absorptiometry (fat mass[FM], fat-free mass[FFM] and percent body fat[BF%]), muscle size by ultrasonography (leg ...


Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier Aug 2019

Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier

Dissertations & Theses in Natural Resources

Humans have transformed much of the natural landscape and are continuing to do so at an accelerated rate, compromising natural areas that serve as important habitat for many species. Roads impact much of the environment as they fragment habitat and introduce traffic noise into the acoustic environment, deferentially affecting wildlife in roadside habitat. I explored how traffic noise affects the detection of birds based on whether their vocalizations were masked by traffic noise. Masked species detection was not affected by an increase in traffic noise amplitude, while there was a negative effect of traffic noise amplitude on unmasked species detection ...

Establishing Enhanced Learning Outcomes In Science For First Generational Undergraduate College Students, Marianna Burks Apr 2019

Establishing Enhanced Learning Outcomes In Science For First Generational Undergraduate College Students, Marianna Burks

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

First-generation students represent an increasing percentage of the demographic for college and university enrollment at both the undergraduate and graduate levels. Since 2001, results from the National Center for Education Statistics Longitudinal Study, indicates ‘higher percentages of first-generations college students attended public postsecondary institutions-76 vs. 72%’ (Redford & Hoyer, 2017). There is insufficient research, however, concerning how first-generation students’ needs are different, even unique, from those students who are second- generation and beyond attending college (National Center for Educational Statistics, 2017). Since this increase of students enrolling in post-secondary education, ‘understanding the needs of first-generation students is imperative more now than ...


Student Perceptions Of Reasons For Lecture And Active Learning, Calan Koch Mar 2019

Student Perceptions Of Reasons For Lecture And Active Learning, Calan Koch

Honors Theses, University of Nebraska-Lincoln

With perceived student resistance to active learning in the classroom, instructors are hesitant to implement such methods into their classroom structure despite how effective they may be. This research seeks to understand student perceptions related to the transition to higher prevalence of active learning techniques. We aimed to find answers to how students perceive the ideal classroom to be structured, what reasons they perceive for lecture and active learning components, and possible explanations to concerns of groupwork during class time. We analyzed 64 interviews with undergraduate biology students at the University of Nebraska- Lincoln, developed coding rubrics from commonly found ...

The Nature Of Science As A Foundation For Fostering A Better Understanding Of Evolution, Craig E. Nelson, Lawrence C. Scharmann, Jean Beard, Lawrence I. Flammer Feb 2019

The Nature Of Science As A Foundation For Fostering A Better Understanding Of Evolution, Craig E. Nelson, Lawrence C. Scharmann, Jean Beard, Lawrence I. Flammer

Faculty Publications: Department of Teaching, Learning and Teacher Education

Misunderstandings of the nature of science (NOS) contribute greatly to resistance to evolutionary theory especially among non-scientific audiences. Here we delineate three extended instructional examples that make extensive use of NOS to establish a foundation upon which to more successfully introduce evolution. Specifically, these instructional examples enable students to consider evolutionary biology using NOS as a lens for interpretation of evolutionary concepts. We have further found, through our respective research efforts and instructional experiences, that a deep understanding of NOS helps students understand and accept the scientific validity of evolution and, conversely, that evolution provides an especially effective context for ...

How Do Teachers Use Comics To Promote Engagement, Equity, And Diversity In Science Classrooms?, Camilla Matuk, Talia Hurwich, Amy Spiegel, Judy Diamond Jan 2019

How Do Teachers Use Comics To Promote Engagement, Equity, And Diversity In Science Classrooms?, Camilla Matuk, Talia Hurwich, Amy Spiegel, Judy Diamond

World of Viruses

Equitable learning opportunities are critical to the goals of science education. However, major curriculum standards are vague on how to achieve equity goals, and educators must often develop their own resources and strategies to achieve equity goals. This study examines how educators used a comic book series designed to interest youth in virology as a way to make science more broadly appealing to their diverse students. We begin with the notion of Pedagogical Design Capacity, which describes a dynamic relationship between teachers and their tools and the ability for teachers to perceive and leverage affordances of artifacts as tools in ...


Student Understanding Of Dna Structure–Function Relationships Improves From Using 3d Learning Modules With Dynamic 3d Printed Models, Michelle E. Howell, Christine S. Booth, Sharmin M. Sikich, Tomáš Helikar, Rebecca Roston, Brain A. Couch, Karin Van Dijk Jan 2019

Student Understanding Of Dna Structure–Function Relationships Improves From Using 3d Learning Modules With Dynamic 3d Printed Models, Michelle E. Howell, Christine S. Booth, Sharmin M. Sikich, Tomáš Helikar, Rebecca Roston, Brain A. Couch, Karin Van Dijk

Biochemistry -- Faculty Publications

Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure–function relationships, such models have not been widely implemented in biochemistry classrooms. Three-dimensional (3D) printing represents an emerging cost-effective means of producing molecular models to help students investigate structure–function concepts. We developed three interactive learning modules with dynamic 3D printed models to help biochemistry students visualize biomolecular structures and address particular misconceptions. These modules targeted specific learning objectives related to DNA and RNA structure, transcription factor-DNA interactions, and DNA ...


"My Paintings Would Be No Different Than A Picture In A Biology Textbook", Andi Kur Jan 2019

"My Paintings Would Be No Different Than A Picture In A Biology Textbook", Andi Kur

UReCA: The NCHC Journal of Undergraduate Research & Creative Activity

I find that there are innate balances in life, universal dichotomies that permeate our understanding of the world. My paintings are about a duality such as this that exists between art and science. We are told from youth that these subjects are poles in constant strain, as miscible as oil in water. I spent thirteen years in school believing that I must choose between the two, that it is unnecessary to carry both with me. Drawn between a distinct love of each, I realized how vehemently I disagreed. Everything: every rock to every tree to every person is suspended between ...


Evolutionary Explanation For Invasive Abilities Of Centaurea Stoebe (Spotted Knapweed) In Introduced Areas, Erin Koren Jan 2019

Evolutionary Explanation For Invasive Abilities Of Centaurea Stoebe (Spotted Knapweed) In Introduced Areas, Erin Koren

UReCA: The NCHC Journal of Undergraduate Research & Creative Activity

Since every invasion and every exotic species presents a new challenge with novel invasion strategies, the invasion of Centaurea stoebe (synonymously referred to as C. maculosa) into North America will be used as a case study to deeply examine invasion strategies. Centaurea stoebe is a short-lived (approximately 3 years) perennial member of the aster family (Broz et al., 2007). It occurs in two different cytotypes, or with two different chromosomal factors. In its home range, it exists in both diploid and tetraploid cytotypes, but only the tetraploid version is present in introduced ranges in North America (See Figure 1; Treier ...


The Impact Of Whoop Technology On Sleep, Recovery, And Performance In Naia Baseball Players, Nolan Harms Dec 2018

The Impact Of Whoop Technology On Sleep, Recovery, And Performance In Naia Baseball Players, Nolan Harms

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

Many key factors – including but not limited to – sleep, nutrition, travel, stress, and practice influence the optimization of athletic performance. Although previous studies have investigated the use of wearable technology in sport to track several such factors, peer-reviewed research specific to WHOOP technology is limited at best. The purpose of this study was to examine the impact of WHOOP technology on sleep, recovery, and batting performance in healthy NAIA baseball players. Data was collected over the course of 4 weeks of in-season play on 10 varsity NAIA baseball players (20.40 ± 0.97 years). All games – 18 total – were played ...

Mammalogy Papers: University of Nebraska State Museum

First paragraph:

On 30 March 2018, the science of mammalogy and the American Society of Mammalogists lost one of the most influential figures of the last half-century. Robert James Baker died quietly at his home in Lubbock, Texas (Fig. 1). He was born on 8 April 1942 to James Simeon Baker and Laura Cooper in Warren, Arkansas. His father was killed during World War II and his mother remarried, resulting in his growing up with six half-siblings. According to Robert’s autobiography in Going afield (330—number refers to specific publication in “Bibliography”), he spent a good deal of his ...

Publications of the Rural Futures Institute

Conclusion

Many rural Nebraskans think it brings shame upon a person to do the following: file personal bankruptcy, apply for food stamps and apply for income assistance. Most rural Nebraskans disagree that the following items bring shame to a person: go to Alcoholics Anonymous or other alcohol treatment, seek mental health care, and go to drug treatment. In general, rural Nebraskans say that residents of their community are more likely than they personally are to think doing the items brings shame upon a person.

At least one-third of rural Nebraskans think the following are a very serious problem or a ...

Conclusion

The proportion of rural Nebraskans accessing the Internet using their cell phone has increased compared to two years ago. But, the proportion subscribing to high-speed Internet service at home remained stable during the past two years. Persons living in or near the smallest communities are less likely than persons living in or near larger communities to have high-speed Internet service at home.

Not many rural Nebraskans report significant limitations from their home Internet service on their ability to do most tasks. At least one in ten report being limited significantly or not being able to play real time video ...


Multiple–True–False Questions Reveal The Limits Of The Multiple–Choice Format For Detecting Students With Incomplete Understandings, Brian Couch, Joanna K. Hubbard, Chad Brassil Jun 2018

Multiple–True–False Questions Reveal The Limits Of The Multiple–Choice Format For Detecting Students With Incomplete Understandings, Brian Couch, Joanna K. Hubbard, Chad Brassil

Faculty Publications in the Biological Sciences

By having students select one answer among several plausible options, multiple–choice (MC) questions capture a student’s preferred answer but provide little information regarding a student’s thinking on the remaining options. We conducted a crossover design experiment in which similar groups of introductory biology students were assigned verbatim questions in the MC format or multiple–true–false (MTF) format, which requires students to separately evaluate each option as either true or false. Our data reveal that nearly half of the students who select the correct MC answer likely hold incorrect understandings of the other options and that the ...

The Impact Of Mentoring On Life Science Undergraduate Mentors, Kari Nelson May 2018

The Impact Of Mentoring On Life Science Undergraduate Mentors, Kari Nelson

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

Universities are increasingly encouraging their undergraduates to become mentors to others, yet relatively little research has been done to empirically understand the impact of this work on the mentors themselves. Therefore, the overall goals of this work were: (1) To evaluate the types of studies that have been conducted on the impacts of serving as an undergraduate mentor; (2) To examine the methodological rigor of recent studies and make recommendations for improvement; and (3) To asses if serving as an undergraduate mentor impacted the critical thinking of the mentors, using a valid and reliable instrument, the California Critical Thinking Skills ...
