Seek, Picture Insect, Google Lens: An Analysis Of Popular Insect Identification Apps Using Photos Of Realistic Quality, Morgan Manderfield

Department of Entomology: Distance Master of Science Projects

Photo-based identification apps for mobile devices have grown in popularity across many fields of organismal biology. While studies have shown that these apps show promise in fields such as botany and ornithology, there is much skepticism surrounding their accuracy and usefulness in entomology. While providing these apps with photos of high quality will undoubtedly lead to the highest accuracy rates, often users submit photos of average quality, e.g., in poor lighting, out of focus, from far away, etc. To quantify realistic accuracy rates of photo-based insect identification apps, this study analyzed three popular apps – Seek, Picture Insect, and Google …

Insects As Indicators Of Climate Change: A Literature Review, Amy Catalano

Department of Entomology: Distance Master of Science Projects

The International Panel on Climate Change (IPCC) has consistently predicted rising global temperatures since it began reporting in 1988. Researchers have noted that climate extremes have been identified beginning in the 1990s and are apparent in various climate indicators. The most recent IPCC reports show that the rate of warming has sped up considerably, and that global warming will increase from pre-industrial levels by 1.5 degrees Celsius in the next 30 years, and possibly by 2 degrees C if considerable mitigation efforts are not put in place (IPCC, 2021). By 2017 global temperatures had already increased by about 1 degree …

(Re)Turning To Freirean Philosophy In Preparing Content Teachers To Work With Multilingual Students, Kara Viesca, Peiwen Wang, Brandon Heinz, Alexa Yunes-Koch

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In 2019, Bettina Love published a call for abolitionist teaching, an effort for educational freedom and racial justice. In her work, she centered the role of theory in teaching calling it a "North Star." She suggested that theory provides teachers a "steadfast tool" that explains the experiences of people minoritized due to racism, sexism, ableism, linguicism, etc., as well as provides language for and knowledge about intersectional issues of injustice. Love literally calls theory a "practical guide" as well as a "location for healing" (Love, 2019, p. 132).

The work of Paulo Freire has long served as the kind of …

“It Was Just My Name!”: A Crt/Crf Analysis Of International Female Graduate Students’ Perception And Experiences Regarding Their Ethnic Name, Peiwen Wang, Xiaoyan Gu, Amanda R. Morales

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Although international female students accounted for 44% of the enrolled international students in the United States (U.S. Department of Homeland Security’s Student and Exchange Visitor Information System, 2020), their experiences regarding their ethnic name are relatively understudied in onomastic literature. This study considers the experiences of eight international female graduate students of Color who are studying at a Midwestern predominantly White university. Utilizing Critical Race Theory (CRT) and Critical Race Feminism (CRF) as the theoretical and analytical lenses, this qualitative phenomenological study collected data through semi-structured, in-depth interviews. We explore the meaning of ethnic names and their connection to participants’ …

Using Complex Behavior To Understand Brain Mechanisms In Health And Disease, Cassandra D. Gipson, Paul L. Soto, Erin S. Calipari, Donna M. Platt, John D. Salamone, Rick A. Bevins

Department of Psychology: Faculty Publications

At this point in the history of the science of behavior, a focus on neuroscience-based outcomes has become dominant in neuropsychiatric fields at the preclinical and clinical levels of analysis. The notion that behavior is caused by brain function, and that changing brain function can alter behavior, has fueled this push to understand these neurobiological mechanisms. Within this conceptual framework and the funding to incentivize its adoption, the neuroscience field grew rapidly with the goal to understand the relation between the brain and behavior. As such, a reductionist perspective emerged whereby neural manipulations of increasing sophistication became required for assessing …

Attachment Anxiety And Avoidance Predict Postnatal Partner Support Through Impaired Affective Communication, Frances C. Calkins, Rebecca L. Brock

Department of Psychology: Faculty Publications

Objective: The purpose of the present study was to investigate perceived difficulties in affective communication as a key mechanism linking attachment anxiety and avoidance during pregnancy to the quality of postpartum support received by partners.

Background: During the postpartum period, partner support has the potential to promote family well-being by mitigating stress related to changes experienced during this transition. Attachment security is one of the most robust predictors of intimate relationship processes and impacts partner communication and support dynamics.

Method: Heterosexual couples (N = 159) completed surveys and semi-structured interviews to obtain measures of attachment security, perceived difficulties in …

Political Identity Biases Americans’ Judgments Of Outgroup Emotion, Ruby Basyouni, Nicholas R. Harp, Ingrid J. Haas, Maital Neta

Department of Psychology: Faculty Publications

Social group identity plays a central role in political polarization and inter-party conflict. Here, we use ambiguously valenced faces to measure bias in the processing of political ingroup and outgroup faces, while also accounting for interparty differences in judgments of emotion at baseline. Participants identifying as Democrats and Republicans judged happy, angry, and surprised faces as positive or negative. Whereas happy and angry faces convey positive and negative valence respectively, surprised faces are ambiguous in that they readily convey positive and negative valence. Thus, surprise is a useful tool for characterizing valence bias (i.e., the tendency to judge ambiguous stimuli …

Safety Splash: Pool Safety For Children And Adults, Rachel Lofton

Honors Program: Senior Projects (Public)

This outreach project was made to address the issue of too many children drowning at pools due to a lack of water safety education. The dissemination of pool safety education is imperative to reduce accidental injuries and drownings. The goal of the Safety Splash video and supplemental materials is to provide pool safety education for children and adults. By encouraging conversations between children and adults before going to the pool, there can be an intervention that reduces the risk of injury and drowning once they arrive. Through research, I compiled information to support the effectiveness of a combination video, pamphlet, …

Wheat Transcriptomic Responses To Extended Feeding By Wheat Curl Mites, Lise Pingault, Tran Kim Ngan Luong, Joe Louis, Gary Hein

Department of Entomology: Faculty Publications

The economic importance of wheat and its contribution to human and livestock diets has been already demonstrated. However, wheat production is impacted by pests that induce yield reductions. Among these pests, wheat curl mite (WCM, Aceria tosichella Keifer) impacts wheat all around the world. WCM are tiny pests that feed within the whorl of developing leaves, and their feeding causes leaf curling by preventing them from unfurling. The curling of the leaves provides a protective niche for the WCM. Additionally, WCM are also the vector of serious viruses in wheat. Little is known regarding the impact of the WCM on …

Relationships Between Proximity To Grocery Stores And Oklahoma Early Care And Education Classroom Nutrition Practices, Bethany D. Williams, Susan B. Sisson, Bryce Lowery, Dipti Dev, Diane M. Horm, Janis E. Campbell, Denise Finneran, Jennifer Graef-Downard

Department of Child, Youth, and Family Studies: Faculty Publications

The study purpose was to determine associations between proximity to grocery stores and Early Care and Education programs’ (i.e., ECEs) classroom nutrition practices and barriers, by ECE context (Head Start, community-based childcare [CBC], and family child care homes [FCCHs]). A statewide cross-sectional survey was implemented in Oklahoma ECEs. Directors reported classroom nutrition practices with the Nutrition and Physical Activity Self-Assessment tool, and barriers to implementation. Locations of 457 grocery stores statewide were determined by in-person audit. Geocoded ECEs were considered within a “low proximity” area if no grocery stores were available within a 0.25-mile radius for urban, or 10-mile radius …

A Life-Course Perspective Of Sex Trafficking Among The Bedia Caste Of India, Rochelle L. Dalla, Kaitlin Roselius, Victoria J. Johnson, Jessie Peter, Trupti Jhaveri Panchal, Ramani Ranjan, Mrinalini Mischra, Sagar Sahu

Department of Child, Youth, and Family Studies: Faculty Publications

Thousands of Indian women and girls enter the commercial sex industry (CSI) annually based solely on membership in particular castes (e.g., Bedia, Nat). CSI-involved females bear the burden of sustaining entire family units on money earned in the sex trade; it is a life-long responsibility with negligible social status or personal indemnity. Based on the life-course developmental theory (Elder, Jr. 1994, 1998) this investigation was intended to examine trafficked women’s experiences within the commercial sex industry across time. Beyond the CSI, we were equally interested in experiences with factors that could promote well-being (i.e., social support) and normative developmental transitions …

Time-varying covariates included year of the study, pain, functional ability, household work disability, parental status, marital status, employment status, and social support. The time-invariant covariates included years since diagnosis, education, race/ ethnicity, and gender. Multivariate multilevel-model analyses were used to estimate associations within people over time.

Results. Patients with RA experience considerable change in …

Pandemic, Politics, And Public Opinion About Crime, Lisa Kort-Butler

Department of Sociology: Faculty Publications

Prior scholarship links ontological insecurities, racial tensions, and health issues to public opinion about crime. This project examined these forces in the context of the 2020 pandemic, racial justice demonstrations, and politics using data from the Nebraska 2020 survey (N=2775). Pandemicrelated insecurities and racial animus were associated with avoiding places in the community, worry about crime, and the belief that police in one’s community are underfunded. Trusting politicians but distrusting health leaders, and viewing COVID as an economic threat but not a health threat were associated with the belief police are underfunded. Results suggest that the politicization of the pandemic …

Sensors capable of measuring this quantity have been around for decades, however, the increasing focus in nano and microscale applications in the industry and academia demands more accurate and smaller devices. This paper reviews some of the methods used to develop heat flux meters targeted to nano and microscale, as well as some calibration processes for the same. A combination of Luminescence and non-luminescence methods for direct and indirect measurement of heat flux will be discussed. A glimpse of what the future …

A Meta-Analysis Examining Technology-Assisted L2 Vocabulary Learning, Aiqing Yu, Guy Trainin

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This meta-analysis examines the effectiveness of technology-assisted second language (L2) vocabulary learning as well as identifies factors that may play a role in their effectiveness. We found 34 studies with 2,511 participants yielding 49 separate effect sizes. Following the procedure developed by Hunter and Schmidt (2004), we corrected for sample size bias and measurement error. The overall effect size for using technology to learn L2 vocabulary was d = 0.64, which is a moderate effect size. The Q statistic indicated a significant variability in effect size, so we followed up with a theory-driven moderator analysis. The results of the moderator …
