ENERGY ASSIMILATION AND THERMOREGULATORY BEHAVIOR IN POPULATIONS OF A VERTEBRATE ECTOTHERM (SCELOPORUS CONSOBRINUS) ALONG A GEOGRAPHIC THERMAL GRADIENT
No full textEctothermic organisms make up a vast majority of animal species and fill many vital roles in ecosystems due to their prevalence. Because ectotherms are inherently affected by the thermal environment, they are severely impacted by environmental issues such as climate change and other human driven processes that may affect thermal habitats. To better understand how ecosystems are affected by changes in climate, we need a greater understanding of how ectothermic organisms respond and adapt to altered environmental temperatures. This study aims to understand some of the adaptational differences between populations of a widespread lizard species, Sceloporus consobrinus, that inhabit a wide variety of thermally distinct environments. We looked into digestive efficiency and what role temperature and behavior may play in the effectiveness of how this species extracts energy from food. We found that there are differences in thermoregulatory behavior between populations of S. consobrinus that are adapted to different thermal environments, and that individuals of this species extract greater amounts of energy from digested food when allowed to freely thermoregulate
Models of Mastery Learning for Computing Education
Get PDFThe application of mastery learning, where students progress through their learning in a self-paced manner until they have mastered specific concepts, is considered appealing for teaching introductory programming courses. Despite its growing popularity in computing and its extensive use in other disciplines, there is no overview of the design of courses that use mastery learning. In this position paper, we present an overview of five mastery learning models and discuss examples of how these can be applied in practice, both in foundational programming as well as more advanced courses. Our analysis focuses on the student progression through the course, the assessment structure, and the support for self-paced learning, including for struggling students. This work provides a greater understanding of mastery learning and its application in a computing education context
Using An Archival Collection in a Student Research and Creative Activity Fair: The Lourdes Gouveia Papers at the University of Nebraska at Omaha
Get PDFDuring the Spring 2022 semester, Claire Du Laney, Outreach Archivist at the University of Nebraska at Omaha (UNO) Archives and Special Collections (ASC), worked with Dr. Brett Kyle and students in International Relations in Latin America (PSCI4280) to introduce political science students to primary source research.[1] Using the Lourdes Gouveia Papers (UNO-0234), students conducted archival research and incorporated those skills into their final projects.[2] The Lourdes Gouveia Papers are the research collection of Dr. Lourdes Gouveia, a UNO professor and founding director of the Office of Latino/Latin American Studies (OLLAS), who studied Latinx immigrants in the Nebraska meat-packing industry from 1988–2016. Areas of research within the collection include immigrant integration, the experiences of Latina women in migrant communities, social services available to Latinx families, and the ethical concerns around beef-packing labor.[3
Nature vs Nurture: Place in Perceval
Get PDFPerceval’s identity as a Welshman has its roots deep in his character, even if he is not aware of it. Raised in ignorance by his mother in an attempt to keep him safe from the dangers of his knightly heritage, Perceval represents a fascinating blend of culture and instinct that makes the crux of his character the age-old argument: nature versus nurture. Has his blood, heritage, and genetic history had more of an impact on him? Or has it been how he was raised, what he was taught as he grew? Much like Perceval himself, the answer is complicated, and a little contradictory
Assessment of a textbook affordability initiative: A framework for measuring the impact on student enrollment and retention outcomes
No full textThe rising costs of textbooks have prompted widespread textbook affordability initiatives in higher education. Programs that reduce student costs and offer increased access have become an integral part of campus strategic planning initiatives. In this case study, we discuss the design, implementation, and assessment of an Affordable Content grant program at a medium sized, R2, urban university. The grant was awarded with a stipulation that the system-wide program will also be assessed. The assessment of the impact and efficacy of affordable course content initiatives requires quantitative strategies often outside academic librarians\u27 expertise. To this end, we partnered with campus stakeholders to leverage their data analysis expertise. Since randomized controlled trials are not always viable in educational research, we used the Propensity Score Matching method to ensure the groups of students were structurally similar. The results of our analysis showed a significant impact on measures of student retention. This study adds to the growing body of literature on measuring the impact of textbook affordability and offers an opportunity to further advocate campus-wide adoption of open pedagogy
Comparing Non-Invasive Survey Techniques for Southern Flying Squirrels (Glaucomys volans) in Nebraska
No full textThe southern flying squirrel (Glaucomys volans) is a threatened species in Nebraska that occurs along the Missouri River in the southeastern corner of the state, but recently, a population was discovered in the city of Lincoln. The method in which G. volans established a population in Lincoln is unknown. A survey of the current distribution in Nebraska is long overdue, thus the most effective survey methods need to be determined. This study investigated and compared two noninvasive survey techniques, ultrasonic detectors and trail cameras, that have recently been used successfully to survey for a similar species, the northern flying squirrel, in North Carolina. I also tested whether bait influenced the effectiveness of either survey technique. This study found that the acoustic detectors were significantly more likely to detect flying squirrels and detected them faster than cameras. It also found that bait did not increase the likelihood or rate of detecting flying squirrels with detectors. For southern flying squirrels at the western edge of their range in Nebraska, acoustic detectors are an effective method for rapid presence/absence surveys
