Purdue University Libraries Open Access Publishing Fund

In the present study, we examined the extent to which teacher-rated self-regulation and directly assessed executive function skills were independently, additively, or synergistically related to academic achievement during the transition to kindergarten. The sample included 126 children (42% female; Mage = 4.73 years) from families with low incomes who participated in a larger evaluation of state-funded preschool. Regression models with children nested in their respective preschool classrooms investigated main effects and moderated effects of teacher-rated self-regulation skills manifested in preschool classroom behaviors and cognitive executive function skills assessed through direct assessments on math, literacy, and vocabulary in the spring of …

A Nosy Neighbor: Purification And Functional Characterization Of Lpg2149, Ashley M. Holahan

The Journal of Purdue Undergraduate Research

Ubiquitination is a process that marks proteins for various cell-signaling pathways, namely protein degradation and other processes. Th ese pathways are essential in a wide array of cellular processes, including defense mechanisms against invading pathogens. Th e ubiquitination process is universally found in all eukaryotic organisms, including plants and animals, and thus plays a vital role in cellular homeostasis. Recently, more discoveries have been made on prokaryotic effector proteins that hijack the ubiquitination system even when they do not possess a ubiquitin system of their own. MavC, also known as lpg2147 (Gan, Nakayasu, Hollenbeck, & Luo, 2019; Puvar et al., …

Multiphase Energetic Experiments: Application Of Multiple Object Tracking, Sarah Davis Finch

The Journal of Purdue Undergraduate Research

The process of using computer vision for multiple-objects tracking is incredibly complex. Thus, simulated data was created to mimic the complexities of more realistic data. These test cases would isolate a few of the inaccuracies of real data and allow the researchers to determine what factor of said data is the most detrimental to the object-tracking process. Due to the large quantity of factors at play, Cotter’s method was used to analyze the significance of each factor. The number of detections and the number of centroids were the main dependent results that were utilized to analyze the data. The overall …

Pharmacy Students As Volunteer Medical Staff For American Diabetes Association Summer Camp, Emily Harvath

Purdue Journal of Service-Learning and International Engagement

For children living with a diagnosis of diabetes, com-munity support and education about proper disease management are critical for the mental and physical health of the child and their family. The experiences offered at summer camps hosted by the American Diabetes Association address both of these needs for the pediatric diabetes community. These camps provide children with the opportunity to participate in a traditional camp experience—swimming, rock climbing, tubing, and more—while giving parents peace of mind in the knowledge that their child’s diabetes will be closely monitored by a team of health care professionals. During my time as volunteer medical …

Heroes At Home: Honoring Our Nation's Veterans, Kayla Vasilko

Purdue Journal of Service-Learning and International Engagement

There are currently 17.42 million veterans living in America today. These heroes dedicated their services in World War II, the Korean War, Vietnam War, and the Gulf War, leaving home and giving up the comforts of stability, family, and guaranteed safety to ensure that America remains a stable and safe place for individuals and families to call home, yet upon returning home themselves, our nation’s veterans have had to face immense hardships. About 40,000 veterans are without shelter in the U.S. on any given night; some of the leading causes of veteran homelessness include PTSD, social isolation, unemployment, and substance …

People and Animals: The International Journal of Research and Practice

The island of Hawaii exhibits extremes in dog welfare ranging from dogs as family members to dogs used as commodities, either as guard or hunting dogs, with many lacking appropriate care. This study offers a preliminary exploration of people’s attitudes toward companion and noncompanion dogs and the health and welfare implications for humans and dogs. Data collection included interviews and surveys conducted among 20 companion dog/human and eight guard dog/human dyads. Blood pressure (BP) was monitored during interviews to assess stress. The results of the interview data led to five themes. The first two themes describing contexts of dog welfare …

Moralizing The Law: Lactating Workers And The Transformation Of Supervising Managers, Elizabeth A. Hoffmann

Department of Sociology Faculty Publications

The Lactation at Work Law amended the Fair Labor Standards Act to mandate employer accommodation of employees’ breast milk expression. Interviews with employees, human resource specialists, and supervising managers in nine industries found that some organizations’ supervising managers, who initially perceived accommodations only as a legal mandate furthering managerial goals, over time changed to understanding lactation accommodations through a children’s-health lens that created morality-driven motivations for legal compliance–a “moralization of the law.” Educational discussions with lactating employees not only provided these supervising managers with insights into lactation at work, but also sensitized them to ethical issues surrounding lactation accommodations.

Why Do Early Mathematics Skills Predict Later Mathematics And Reading Achievement? The Role Of Executive Function, Dieuwer Ten Braak, Ragnhild Lenes, David J. Purpura, Sara A. Schmitt, Ingunn Størksen

Purdue Center for Early Learning Faculty and Staff Publications

A robust association between young children’s early mathematical proficiency and later academic achievement is well established. Less is known about the mechanisms through which early mathematics skills may contribute to later mathematics and especially reading achievement. Using a parallel multiple mediator model, the current study investigated whether executive function (integration of working memory, inhibition, and cognitive flexibility) can explain the relations between early mathematics skills and elementary school mathematics and reading achievement. Data in this longitudinal study were collected from 243 children during the last year of early childhood education and care (kindergarten ages 5 and 6 years), 1 year …

Determining The Accuracy Of Holstein Bull Semen Prices With A Two-Tier Efficiency Model, Loren W. Tauer

Journal of Applied Farm Economics

The pricing accuracy of dairy bull semen available for artificial insemination is investigated using a price model cast in terms of a two-tier efficiency model, which allows estimating an overprice and underprice given the net return the bull’s daughter is expected to contribute to the farm based upon the transmittable trait characteristics of a bull. The estimation produces statistically significant coefficients, including the coefficients for the overpricing and underpricing of the semen. The average estimate of overpricing is around 25%, and the average estimate of underpricing is around 33%. As expected, low semen prices tend to be underpriced and high …

Farm Efficiency And Productivity Growth: The Effect Of Commodity Prices, Elizabeth Canales, Jason S. Bergtold, Allen Featherstone

Journal of Applied Farm Economics

Crop prices can affect farm productivity through input- output decisions. This study assesses the relationship between crop prices and productivity changes among a sample of Kansas farms. The changes in total factor productivity are evaluated using a nonparametric approach with a Malmquist productivity index and potential drivers of technical efficiency and productivity change are analyzed. Farms with higher leverage and greater diversification are likely to be more efficient and experience productivity change. Lower productivity occurred during years with higher crop prices, suggesting that innovation is more likely to occur when margins are tight.

Questions To Measure Enjoyment Of And Satisfaction With Physical Activity: Are They Appropriate For Use In An Older Population?, Mary Katherine Huffman, Sharon L. Christ, Kenneth F. Ferraro, David B. Klenosky, Kristine Marceau, Steve Amireault

Purdue University Libraries Open Access Publishing Fund

Background and Objectives

Enjoyment of and satisfaction with physical activity have been proposed as two actionable mechanisms to promote sustained engagement in physical activity. An accurate understanding of how, why, and for whom these two mechanisms work (or not) in response to a particular intervention strategy is contingent on having suitable measures for the population of interest. This study aims to determine whether the Physical Activity Enjoyment Scale-8 and a novel approach to the measurement of satisfaction with physical activity are suitable for use among older adults (Mage = 66.25 years; range = 55–91 years).

Understanding Informed Design Through Trade-Off Decisions With An Empirically-Based Protocol For Students And Design Educators, Molly H. Goldstein, Robin S. Adams, Senay Purzer

Journal of Pre-College Engineering Education Research (J-PEER)

Trade-off decisions, which necessitate striking a balance between two or more desirable but competing features, are a crucial part of design practice. However, they are known to be difficult for student designers to make. While designers, educators, and researchers have numerous methods to assess the quality of design artifacts, these methods are not necessarily easy to use, nor do they indicate design competency. Moreover, they are not grounded in a definition of engineering design. The objectives of this study were twofold. First, we developed a protocol to depict design artifact quality through the lens of design trade-off decisions. We aimed …

Enhancing Engineering Identity Among Boys Of Color, Jerrod Henderson, Virginia Snodgrass Rangel, James Holly Jr, Rick Greer, Mariam Manuel

Journal of Pre-College Engineering Education Research (J-PEER)

Black and Brown men continue to be underrepresented in engineering. One explanation for the dearth of Black and Latino men in engineering is that engineering (and STEM) identity often is not inclusive of People of Color. As a result, Black and Brown boys may be less likely to become interested in STEM subjects. The purpose of this study, then, was to investigate how the components of one afterschool engineering program tap into engineering identity formation among fourth- and fifth-grade Black and Brown boys. Leveraging research on the STEM and engineering identity, we argue that the program and its key components …

Purpose: This study explored the perspectives of SD training organizations and factors for human health care providers to consider before recommending a veteran with PTSD for a SD versus an ESA. The researchers identified information that providers should give organizations to guide the SD training and placement process. …

Evaluation Of A Combined Mhe-Nmpc Approach To Handle Plant-Model Mismatch In A Rotary Tablet Press, Yan-Shu Huang, M Ziyan Sheriff, Sunidhi Bachawala, Marcial Gonzalez, Zoltan K. Nagy, Gintaras V. Reklaitis

Department of Chemistry Faculty Publications

The transition from batch to continuous processes in the pharmaceutical industry has been driven by the potential improvement in process controllability, product quality homogeneity, and reduction of material inventory. A quality-by-control (QbC) approach has been implemented in a variety of pharmaceutical product manufacturing modalities to increase product quality through a three-level hierarchical control structure. In the implementation of the QbC approach it is common practice to simplify control algorithms by utilizing linearized models with constant model parameters. Nonlinear model predictive control (NMPC) can effectively deliver control functionality for highly sensitive variations and nonlinear multiple-input-multiple-output (MIMO) systems, which is essential for …

Systemic Copper Disorders Influence The Olfactory Function In Adult Rats: Roles Of Altered Adult Neurogenesis And Neurochemical Imbalance, Sherleen Xue-Fu Adamson, Wei Zheng, Zeynep Sena Agim, Sarah Du, Sheila Fleming, Jason Cannon

School of Health Sciences Faculty Publications

Disrupted systemic copper (Cu) homeostasis underlies neurodegenerative diseases with early symptoms including olfactory dysfunction. This study investigated the impact of Cu dyshomeostasis on olfactory function, adult neurogenesis, and neurochemical balance. Models of Cu deficiency (CuD) and Cu overload (CuO) were established by feeding adult rats with Cu-restricted diets plus ip. injection of a Cu chelator (ammonium tetrathiomolybdate) and excess Cu, respectively. CuD reduced Cu levels in the olfactory bulb (OB), subventricular zone (SVZ), rostral migratory stream (RMS), and striatum, while CuO increased Cu levels in these areas. The buried pellet test revealed both CuD and CuO prolonged the latency to …

Designing A Computer-Vision Application: A Case Study For Hand-Hygiene Assessment In An Open-Room Environment, Chengzang Zhong, Amy R. Reibman, Hansel A. Mina, Amanda J. Deering

Department of Food Science Faculty Publications

Hand-hygiene is a critical component for safe food handling. In this paper, we apply an iterative engineering process to design a hand-hygiene action detection system to improve food- handling safety. We demonstrate the feasibility of a baseline RGB-only convolutional neural network (CNN) in the restricted case of a single scenario; however, since this baseline system performs poorly across scenarios, we also demonstrate the application of two methods to explore potential reasons for its poor performance. This leads to the development of our hierarchical system that incorporates a variety of modalities (RGB, optical flow, hand masks, and human skeleton joints) for …

Department of Entomology Faculty Publications

Postharvest management of grain and seed is a challenge among smallholder farmers. Limited information is available on how smallholder farmers in eastern Democratic Republic of Congo (DRC), who have been exposed to multiple conflicts, manage grain and seed after harvest. We interviewed 690 smallholder farmers in Lubero (Baswagha chiefdom) and Rutshuru (Bwisha and Bwito chiefdoms) territories of the North Kivu province of the DRC to assess how they dried and stored their crops. Results reveal that 95% and 80% farmers produced beans and maize, respectively. About half of respondents in Bwisha grew soybean, suggesting production diversification using conflict-resistant crops to …

Department of Animal Sciences Faculty Publications

Inner-Mongolia Sanhe cattle are well-adapted to low-temperature conditions, but the metabolic mechanisms underlying their climatic resilience are still unknown. Based on the ¹H Nuclear Magnetic Resonance platform, 41 metabolites were identified and quantified in the serum of 10 heifers under thermal neutrality (5 °C), and subsequent exposure to hyper-cold temperature (−32 °C) for 3 h. Subsequently, 28 metabolites were pre-filtrated, and they provided better performance in multivariate analysis than that of using 41 metabolites. This indicated the need for pre-filtering of the metabolome data in a paired experimental design. In response to the cold exposure challenge, 19 metabolites associated …

Fine Carbohydrate Structure Of Dietary Resistant Glucans Governs The Structure And Function Of Human Gut Microbiota, Arianna D. Romero Marcia, Tianming Yao, Ming-Hsu Chen, Renee E. Oles, Stephen R. Lindemann

Department of Food Science Faculty Publications

Increased dietary fiber consumption has been shown to increase human gut microbial diversity, but the mechanisms driving this effect remain unclear. One possible explanation is that microbes are able to divide metabolic labor in consumption of complex carbohydrates, which are composed of diverse glycosidic linkages that require specific cognate enzymes for degradation. However, as naturally derived fibers vary in both sugar composition and linkage structure, it is challenging to separate out the impact of each of these variables. We hypothesized that fine differences in carbohydrate linkage structure would govern microbial community structure and function independently of variation in glycosyl residue …

Socioeconomic Status Of Second-Generation Southeast Asians: New Evidence And Analysis, Wayne Carroll

This study uses a large microdata sample from the American Community Survey to describe and compare the socioeconomic status of Southeast Asian American adults and native-born white adults. Results are disaggregated by gender, generation (Generation 1.5 and Generation 2), and ethnic group (Hmong, other Laotian, Cambodian, and Vietnamese). Regression analysis – controlling for age, educational attainment, and other factors – shows that native-born white …

Integration Of A Smart Grid In The United States, Katie Buchholtz, Cooper Fetters, Cooper Lecomp

Student Papers in Public Policy

In February 2021, the Texas power grid experienced widespread outages for days during a severe winter storm. The lack of fine control on grid technology and modernized infrastructure left hundreds of thousands of residents freezing in their homes instead of manageable short-term rolling blackouts. The electrical grid in the United States has not sufficiently modernized to keep up with the rise in technology developing throughout the United States.

Without modernization and necessary improvements, limitations in the grid will expose themselves as widespread outages affecting residents, infrastructure, and companies across the United States. Transitioning the United States to a smart grid …
