An Analysis Of Retention And Development Of Numeracy Skills In Undergraduates, Lisa Kuehne

Arts & Sciences Graduate Student Theses and Dissertations

Numeracy is considered an important outcome of a student's education by educators, administrators and future employers. This work describes the research, development and testing involved in the creation of a new online multiple-choice instrument designed to detect changes in levels of numeracy skills in undergraduate students. Responses from more than 5,000 students at a selective R1 university on the General Education Numeracy Assessment (GENA) test were collected. A psychometric evaluation of the test showed that the test is a reliable instrument for measuring numeracy. Further analysis using a linear mixed-effects model showed that student scores were significantly higher when taken …

Transcribed Ultraconserved Regions Are Associated With Clinicopathological Features In Breast Cancer, Erika Pereira Zambalde, Douglas Adamoski, Daniela Fiori Gradia, Iris Rabinovich, Ana Carolina Rodrigues, Cristina Ivan, Enilze M S F Ribeiro, George Adrian Calin, Jaqueline Carvalho De Oliveira

Faculty, Staff and Student Publications

Ultraconserved regions (UCRs) are 481 genome segments, with length longer than 200 bp, that are 100% conserved among humans, mice, and rats. The majority of UCRs are transcriptionally active (T-UCRs) as many of them produce non-coding RNAs. In a previous study, we evaluated the expression level of T-UCRs in breast cancer (BC) patients and found that 63% of transcripts correlated with some clinical and/or molecular parameter of BC. In this study, we delved into the expression levels of 12 T-UCRs and correlated them with clinicopathological parameters, immunohistochemical markers, and overall survival in two breast cancer cohorts: TCGA and Brazilian patients. …

Characterizing The Impact Of Postharvest Temperature Stress On Polyphenol Profiles Of Red And White-Fruited Strawberry Cultivars, Alyssa N. Smith

USF Tampa Graduate Theses and Dissertations

All living organisms have developed mechanisms that help them prevent internal stress and survive under harsh conditions. For fruits, specifically strawberries, stress is fought against primarily by increasing the synthesis of polyphenols, which are secondary plant metabolites with bioactive activity. Characterizing these bioactive compounds and the differences between strawberry cultivars can be vital for strawberry breeders. Furthermore, understanding the mechanisms that trigger the synthesis of polyphenols and their levels within different strawberry cultivars will provide breeders with tools to successfully identify cultivars with higher resistance to pre- and postharvest stressors. To gain that understanding, this study aimed to characterize the …

Emotion Recognition With Audio, Video, Eeg, And Emg: A Dataset And Baseline Approaches, Jin Chen, Tony Ro, Zhigang Zhu

Publications and Research

This paper describes a new posed multimodal emotional dataset and compares human emotion classification based on four different modalities - audio, video, electromyography (EMG), and electroencephalography (EEG). The results are reported with several baseline approaches using various feature extraction techniques and machine-learning algorithms. First, we collected a dataset from 11 human subjects expressing six basic emotions and one neutral emotion. We then extracted features from each modality using principal component analysis, autoencoder, convolution network, and mel-frequency cepstral coefficient (MFCC), some unique to individual modalities. A number of baseline models have been applied to compare the classification performance in emotion recognition, …

The Type And Quantity Of Plant Litter Influences The Plant Functional Group Growth In An Alpine Meadow, Zhouwen Ma, Fujiang Hou

IGC Proceedings (1977-2023)

Plant functional group (PFG) diversity in a grassland is an important measure of productivity and health. Litter is known to be major driving factors of soil-grass feedbacks in natural grassland. The shift in PFG composition is a significant change that can result many ecological consequences such as litter composition and dynamics (Dong et al., 2019). Decomposition of litter can affect the nutrient and allelochemicals cycling of soil, which affects seed germination and establishment of seedlings (Yuan et al., 2015). Furthermore, PFG characteristics can vary via inputs of the quality or quantity of litter (Galvánek & Lepš, 2012). These compositional changes …

The Functional Importance Of Forbs In Grassland Ecosystems, F. Siebert, C. Morris, S. Chamane, N. Ntuli, S. J. Siebert

IGC Proceedings (1977-2023)

Herbaceous vegetation in grassland ecosystems is characterised by grass dominance in a species-rich forb-grass mixture. Forbs (i.e. the non-graminoid herbaceous component) represent the largest proportion of total species- and functional richness, which secure important ecosystem functions. Although grasses remain the most important forage source, certain forb species provide nutritious food sources for herbivores. Moreover, forbs provide food- and habitat sources to enhance invertebrate diversity and hence, agricultural food security through the maintenance of healthy pollinator communities. Important food and medicinal sources for human livelihoods in developing countries are also largely contributed by forbs. However, the dynamics and ecology of forb …

The Effects Of Chemical And Mechanical Control Of Woody Plants On Resprouting And Seedling Production In Communal Rangelands, P. Monegi, N. R. Mkhize, T. J. Tjelele, D. Ward, Z. Tsvuura

IGC Proceedings (1977-2023)

In many African countries, communal rangelands are threatened by woody plant encroachment. We sought to explore potential solutions for communal ranchers that would be cost-effective. We conducted two field experiments to determine (1) the effects of various tree removal treatments (10%, 20%, 50%, 75% and 100%), and herbicide application on resprouting ability and vigour of several woody plant species; and (2) the effectiveness of Tree Poppers® (a weed wrench) as a low-cost mechanical control tool to physically uproot seedlings and saplings of woody species. In the first experiment, we examined 12 plant species from 20 plots (30 m x 30 …

‘Cachena’, A Bovine Rustic Portuguese Extensively Reared Autochthonous Breed: Meat Texture Analysis, M. E. Potes, S. Ricardo-Rodrigues, M. Laranjo, A. C. Agulheiro-Santos, M. Elias

IGC Proceedings (1977-2023)

‘Cachena’ is one of the world’s smallest bovine breeds. Extremely rustic and wild, they are extensively reared, and fed with natural pastures. Meat valorisation is essential to preserve this breed, with a limited livestock.

‘Cachena’’s meat is tender, juicy, low-fat, and highly appreciated due to the association of animal, terroir and producer, balanced by the ecosystem’s sustainability.

The aim of this study was to increase the weight of Longissimus dorsi (LD) and Psoas major (PM) muscles, without depreciating their sensory quality.

Two groups of 16 animals were slaughtered: (A) 9-17 months old animals with 140-225 kg slaughter live weight (SLW); …

Assessing Feed Gaps On Smallholder Livestock Farms In Limpopo: Production System And Coping Strategies, S. A. Lamega, M. Komainda, M. P. Hoffmann, J. J. Odhiambo, K. K. Ayisi, J. Isselstein

IGC Proceedings (1977-2023)

Smallholder farms in southern Africa are predominantly mixed crop-livestock systems and often characterized by low productivity. Therefore, providing sufficient forage becomes a challenge that results first in feed gaps, i.e. the difference between the demand for and supply of forage, and secondly, in nutrient mining of the soil due to the overuse of the resources. However, the availability of forage follows potentially seasonal patterns. Hence, a key entry point for any intervention strategies for improvement is an assessment of forage quantity and quality throughout the year. Against this background, we investigated six locations, smallholders’ cattle production systems and their adaptation …

Relationships Between Physiological And Self-Reported Assessment Of Cancer-Related Fatigue, Trista Olson, Kevin D. Dames, Jeremy D. Smith, Reid Hayward

International Journal of Exercise Science

International Journal of Exercise Science 15(3): 177-190, 2022. The purpose of this study was to evaluate the relationships between subjective, self-reported cancer related fatigue (CRF) and objective measures of muscular strength and fatigability in cancer survivors. A total of 155 cancer survivors (60 ± 13 years of age) completed a questionnaire for the assessment of CRF, along with assessments of handgrip strength, quadriceps strength and fatigability (reduced force/torque). Fatigability was measured by completing 15 maximal isokinetic contractions of the knee extensors (QFI). Spearman’s rho correlation coefficients were calculated as pairwise combinations of the numerical and categorical dependent measures. Categorical variables …

Evaluating The Effect Of Shoes With Varying Mass On Vertical Ground Reaction Force Parameters In Short-Term Running, Bahador Keshvari, Steven Alevras, Juergen Mitternacht, Veit Senner

International Journal of Exercise Science

International Journal of Exercise Science 15(1): 191-205, 2022. Past investigations have revealed that running shoes affect ground reaction force parameters. However, these studies are unclear as to whether these changes, which occur while running in different shoe types of differing masses, are the result of the structural design or the mass of the shoe. The main aim of this study is to evaluate the effect of shoe mass on vertical ground reaction force parameters: active peak and impulse. Methods. 21 male runners (24.52 years old (± 3.09) and 77.13kg (± 7.9)) participated in the experiment. A baseline shoe (BS) …

The Social Networks Of Manureshed Management, Gwendwr Rhiannon Meredith, Sheri Spiegal, Peter J. A. Kleinman, Daren Harmel

School of Natural Resources: Faculty Publications

Manureshed management—the strategic use of manure nutrients that prioritizes recycling between livestock systems and cropping systems—provides a comprehensive framework for sustainable nutrient management that necessitates the collaboration of many actors. Understanding the social dimensions of collaboration is critical to implement the strategic and technological requirements of functional manuresheds. To improve this understanding, we identified aspirational networks of actors involved in manureshed management across local, regional, and national scales, principally in the United States, elucidating key relationships and highlighting the breadth of interactions essential to successful manureshed management. We concluded that, although the social networks vary with scale, the involvement of …

Evidence For A Semisolid Phase State Of Aerosols And Droplets Relevant To The Airborne And Surface Survival Of Pathogens, Erik Huynh, Anna Olinger, David Woolley, R. K. Kohli, J. M. Choczynski, J. F. Davies, K. Lin, L. C. Marr, Ryan D. Davis

Chemistry Faculty Research

The phase state of respiratory aerosols and droplets has been linked to the humidity-dependent survival of pathogens such as SARS-CoV-2. To inform strategies to mitigate the spread of infectious disease, it is thus necessary to understand the humidity-dependent phase changes associated with the particles in which pathogens are suspended. Here, we study phase changes of levitated aerosols and droplets composed of model respiratory compounds (salt and protein) and growth media (organic-inorganic mixtures commonly used in studies of pathogen survival) with decreasing relative humidity (RH). Efflorescence was suppressed in many particle compositions and thus unlikely to fully account for the humidity-dependent …

Principles Of Holistic Resource Management: Investing In Self-Education, Pete Bauman

SDSU Beef Day 2022 Summary Publication

Study Description:

First developed as a concept for approaching grazing resources management by Alan Savory in the 1970’s as a means of combating poor grazing practices, the concept of Holistic Management has evolved in the modern era to Holistic Resource Management, or in some cases “Wholistic” Resource Management, suggesting a more inclusive approach to overall planning and assessment beyond developing a sustainable grazing plan.

In simplified terms, a complete Holistic Resource Management plan for an agricultural businesses ultimately embraces a core concept that centers on the original ‘Triple Bottom Line’ accounting philosophy where the three “P’s” of profit, people, and …

As local disease control improves, the public health impact of brain metastases (BrM) continues to grow. Molecular features are frequently different between primary and metastatic tumors as a result of clonal evolution during neoplasm migration, selective pressures imposed by systemic treatments, and differences in the local microenvironment. However, biomarker information in BrM is not routinely obtained despite emerging evidence of its clinical value. We review evidence of discordance in clinically actionable biomarkers between primary tumors, extracranial metastases, and BrM. Although BrM biopsy/resection imposes clinical risks, these risks must be weighed against the potential benefits of assessing biomarkers in BrM. First, …

Cold Shock Induces A Terminal Investment Reproductive Response In C. Elegans, Leah Gulyas, Jennifer R. Powell

Biology Faculty Publications

Challenges from environmental stressors have a profound impact on many life-history traits of an organism, including reproductive strategy. Examples across multiple taxa have demonstrated that maternal reproductive investment resulting from stress can improve offspring survival; a form of matricidal provisioning when death appears imminent is known as terminal investment. Here we report a reproductive response in the nematode Caenorhabditis elegans upon exposure to acute cold shock at 2 °C, whereby vitellogenic lipid movement from the soma to the germline appears to be massively upregulated at the expense of parental survival. This response is dependent on functional TAX-2; TAX-4 cGMP-gated channels …

Examining The Relationship Among Civic Attitudes, Civic Engagement Behaviors, And A Sense Of Community In A Sample Of Nurses, Catherine Rewakowski

Dissertations

Nurses are called to advocate for those they serve, and civic engagement is a way to advocate for health-related issues. However, there is sparse evidence of frequency and types of civic activities in which professional nurses engage. A review of literature found that sense of community and civic attitudes are constructs shown to influence civic participation but are not well-studied among professional nurses. The purpose of this study is to gain an understanding of civic engagement among nurses by examining civic engagement activities and factors that influence engagement.

Pathogenic Tnf-Α Drives Peripheral Nerve Inflammation In An Aire-Deficient Model Of Autoimmunity, Yan Wang, Lily Guo, Xihui Yin, Ethan C Mccarthy, Mandy I Cheng, Aline T Hoang, Ho-Chung Chen, Anushi Y Patel, Denise Allard Trout, Erin Xu, Natalie Yakobian, Willy Hugo, James F Howard, Katherine M Sheu, Alexander Hoffmann, Melissa G Lechner, Maureen A Su

Immune cells infiltrate the peripheral nervous system (PNS) after injury and with autoimmunity, but their net effect is divergent. After injury, immune cells are reparative, while in inflammatory neuropathies (e.g., Guillain Barré Syndrome and chronic inflammatory demyelinating polyneuropathy), immune cells are proinflammatory and promote autoimmune demyelination. An understanding of immune cell phenotypes that distinguish these conditions may, therefore, reveal new therapeutic targets for switching immune cells from an inflammatory role to a reparative state. In an autoimmune regulator (Aire)-deficient mouse model of inflammatory neuropathy, we used single-cell RNA sequencing of sciatic nerves to discover a transcriptionally heterogeneous cellular landscape, including …

Modeling Defect Mediated Color-Tunability In Leds With Eu-Doped Gan-Based Active Layers, Hayley J. Austin, Brandon Mitchell, Dolf Timmerman, Jun Tatebayashi, Shuhei Ichikawa, Yasufumi Fujiwara, Volkmar Dierolf

Physics & Engineering Faculty Publications

Color tunability from red to orange to yellow has been demonstrated in GaN-based LED devices with Eu-doped GaN layers as the active region. Under current injection, this is achieved by varying the current density and the pulse conditions. The underlying mechanism behind this color tunability is a redistribution of energy among the D-5(J) states of a Eu3+ ion. This energy shuffling is facilitated by a local defect that has been neglected in previous modeling work. Including this defect allows for a quantitative prediction of the relative time-averaged populations of the Eu3+ ion's D-5(0) and D-5(1) states. Extracting, from experimental results, …
