OER Action Plan for Kansas State University’s Open Alternative Textbook Initiative
Get PDFThis report submitted in completion of the Open Educational Network's OER Librarian Certification program examines the K-State Open Alternative Textbook Initiative (OATI) and its needs past, present, and future. It creates a list of goals and proposes new metrics for that will help bring the project into its 10th year (2023) with success, community, and sustainability in mind. The report is written from the perspective of the Scholarly Communication and Copyright Librarian who has met the administrative needs of the project since February of 2020. This report serves as a checklist and proposal moving forward but also as a resource to other OER librarians/enthusiasts interested in the administration and future of the OATI. The introduction provides an overview on how K-State administers its program, followed by sections that lay out needs and possible solutions for moving forward with the project, and it ends with an appendix that provides an overview of OATI reporting and administration. The documents in the appendices are licensed from the Open Alternative Textbook Initiative for others to reuse in their OER efforts
Developing a Prism Qualification Test to Ensure Adequate Splitting Resistance in Pretensioned Concrete Railroad Ties
Get PDFThis report presents the results from research that evaluated the effect of wire indentation type, edge distance, and the strength of concrete at de-tensioning on longitudinal splitting in pretensioned concrete railroad ties. Four-wire pretensioned concrete prisms were cast with varying reinforcement types and edge distances and the resulting splitting crack lengths were carefully measured. Results showed that concrete edge distance was the most significant factor affecting longitudinal splitting cracks, with reinforcement indentation type also playing a key role. This work resulted in the successful development of a qualification test to ensure adequate splitting resistance in pre-tensioned concrete railroad ties. This test was formally adopted as section 4.2.4 in Chapter 30 of the 2021 AREMA Manual for Railway Engineering
Lessons from local governance and collective action efforts to manage irrigation withdrawals in Kansas
Get PDFThis study evaluates four groundwater management plans to increase the understanding of how local governance and collective action can be effectively implemented to manage irrigation withdrawals in Kansas. The results of our analysis demonstrate five key lessons that highlight the challenges of collective action efforts to manage common-pool resources in a developed country setting. First, the four management plans generally follow Ostrom’s design principles for collective action. However, there are important areas—particularly boundaries and allocations definition—where the management plans could be improved to better align with Ostrom’s design principles. Second, a majority of farmers agree that action is needed to reduce the rate of aquifer depletion but management plans have not substantially reduced water use. Third, management plans that allow for voluntary participation have not received more support than those that require mandatory compliance, perhaps due to the classic free-rider problem. Fourth, there is no clear evidence that heterogeneous benefits from management explain support within a management area. Fifth, groundwater users generally perceive that they have an acceptable level of information. Our analysis highlights the significant challenges facing successful collective action efforts to manage water in the USA. and that the efforts are most likely to be successful when they are small-scale, mandatory, and involve users in the formation process
Community and the choral program: nurturing lifelong, independent musicians in vocal ensembles
Get PDFMaster of MusicDepartment of Music, Theatre, and DanceJulie Yu OppenheimIn this report, I will describe my journey towards providing my students with more autonomy in the choral rehearsal. I provide evidence of student autonomy as they improvise, select literature, and travel on the path to independence. Because of the specific restrictions put on music classes during the 2020-2021 school year, I discovered that my singers needed an opportunity to take back control in one way or another. In doing this, it is my personal goal to allow freer conversations and experimentations to be the norm, not the exception, in my ensembles. Much of this change in my thought process has come from examining my own teaching philosophy and the expectations of a singer that has graduated through my program.
By attending Kansas State University, I have been privileged to broaden my sense of what it means to be a music educator. Although having previously thought of myself as a well- rounded educator, my experiences in this program have shaped me into finally realizing that goal. Entering this program with the desire to be a better music educator now sees me leaving the program as a better human for all students and teachers that I encounter. The connection that I found in my professors and colleagues is one that I now hope to instill into my program and subsequent students. The absence of these experiences during the COVID-19 pandemic has shifted the way that I view my role in music education. The past year has taught me, if nothing else, that music is a communal activity desired by all. Whether performing, attending, or working behind the scenes, all aspects of the musical experience seek to tighten the bond between its participants
Enhanced extreme ultraviolet high-harmonic generation from chromium-doped magnesium oxide
Get PDFHigh-order harmonic generation (HHG) from crystals is emerging as a new ultrashort source of coherent extreme ultraviolet (XUV) light. Doping the crystal structure can offer a new way to control the source properties. Here, we present a study of HHG enhancement in the XUV spectral region from an ionic crystal, using dopant-induced vacancy defects, driven by a laser centered at a wavelength of 1.55 μm. Our numerical simulations based on solutions of the semiconductor Bloch equations and density-functional theory are supported by our experimental observations and demonstrate an increase in the XUV high harmonic yield from doped bulk magnesium oxide (MgO) compared to undoped MgO, even at a low defect concentration. The anisotropy of the harmonic emission as a function of the laser polarization shows that the pristine crystal's symmetry is preserved. Our study paves the way toward the control of HHG in solids with complex defects caused by transition-metal doping
Importance of one- and two-photon transitions in the strong-field dissociation of NO2+
Get PDFEmploying a coincidence three-dimensional momentum imaging technique, we investigate the ultrafast, intense laser-induced dissociation of a metastable NO2+ ion beam into N++O+. Based on the kinetic energy release and angular distributions, measured using both 774-nm and second-order-harmonic 387-nm pulses, we show that the main processes driving dissociation in pulses of about 1014W/cm2 peak intensity are one- and two-photon transitions from the X2Σ+ ground state to the A2Π first-excited state. First-order perturbation theory calculations also corroborate these findings
Blinded, randomized, placebo-controlled study of the efficacy of bupivacaine liposomal suspension using static body weight distribution and subjective pain scoring in dogs after tibial plateau leveling osteotomy (TPLO) surgery
Get PDFMaster of Science in Biomedical SciencesDepartment of Clinical SciencesDavid UpchurchObjective: To compare the analgesic effect of surgical wound infiltration with liposomal bupivacaine (LB) to saline placebo in dogs after tibial plateau leveling osteotomy (TPLO).
Study Design: Blinded, randomized, placebo-controlled clinical prospective study
Animals: 15 client-owned dogs receiving liposomal bupivacaine and 17 dogs receiving an equivalent volume of saline placebo, all with confirmed unilateral cranial cruciate ligament insufficiency.
Methods: Preoperatively and up to 48 hours after surgery, Glasgow Composite Measure Short Form (CMPS-SF) pain scores were assigned and using a weight distribution platform, static body weight distribution (%BW[subsctipt dist]) to the operated limb was measured. Postoperatively, dogs also received carprofen 2.2 mg/kg subcutaneously every 12 hours. Rescue analgesia was provided. Treatment success was defined as not requiring rescue analgesia over the 48 hour postoperative period.
Results: There was no difference between treatment success, postoperative opioid consumption, CMPS-SF pain scores, or %BW[subscript dist] in dogs that received surgical wound infiltration with LB compared with those receiving saline placebo, following TPLO. There was no linear correlation between CMPS-SF pain scores and %BW[subscript dist].
Conclusion: For the population of dogs that underwent TPLO and received postoperative carprofen at our institution, LB did not provide an analgesic effect discernable by success/failure analysis, CMPS-SF pain scores, or %BW[subscript dist] measurement using a weight distribution platform, compared with saline placebo.
Clinical Significance (or Impact): LB may not provide detectable analgesia for dogs recovering from TPLO and receiving postoperative carprofen
Understanding consumers’ emotions and sensory experience for beauty care products
Get PDFDoctor of PhilosophyDepartment of Food, Nutrition, Dietetics and HealthMartin TalaveraUnderstanding consumer experience related to hedonic, sensory, and emotional aspects of products is the key to driving consumer-centric product design for the beauty care category. This dissertation conducted three independent studies aiming to explore consumer experience of beauty care products from two perspectives: liking and beyond liking (emotions), based on conventional sensory and consumer data and online product reviews.
The objective of Chapter 2 was to develop an emotion lexicon that could be used to profile consumers’ emotional responses to beauty care products in sensory and consumer tests. The lexicon was developed in four main steps: sourcing terms from online product reviews, term identification and categorization, term refinement, and term validation. The final emotion lexicon consists of 37 positive emotions and 2 negative emotions. Recommendations on the application of this lexicon to each of the three categories of beauty care (skincare, hair care and makeup) were provided. The validated emotion lexicon from this study is readily applicable to other emotion research for skincare, hair care and makeup.
Chapter 3 explored sensory drivers of liking and emotional associations for beauty care products. Hand creams were used as testing samples to be evaluated for sensory characteristics and consumer perception. First, the sensory space (aroma, appearance, texture & skinfeel) of twelve hand creams was profiled by a highly trained descriptive panel using a modified flavor/texture profile approach. Then, seven hand creams selected from the descriptive sensory space were rated for overall liking, emotions using the lexicon developed from Chapter 2, and consumer characterization using check-all-that-apply (CATA) in a home use test (HUT) with a hundred female consumers from the Kansas City area. Cluster analysis and external preference mapping identified three consumer clusters with different liking patterns: the thick & waxy-texture likers, mild scent & low-medium-thickness likers, and strong-scent likers. Consumers with different liking patterns differed in their emotional associations with sensory characteristics of hand creams. However, high intensities of certain aroma attributes seemed to elicit high-arousal emotions for all groups. The findings of this study could guide the development of new hand cream products targeting different consumer segments.
Chapter 4 explored consumer experience for hand cream products from the “voice of consumers”-online product reviews. A total of 17, 581 reviews representing 46 hand creams of different brands, price points, and sensory attributes were collected from Amazon and Ulta Beauty using a scraping software. Topic modeling using Latent Dirichlet allocation (LDA) identified five major topics consumers mentioned in these online reviews: greasiness & residue of the product, scent/fragrances of the product, skin feel & efficacy of the product, consumers’ skin issues, and occasions when to apply the product. Term frequency–inverse document frequency (tf-idf) calculated for each rating group suggested that unpleasant scent and overall dissatisfied quality were the main reasons why consumers gave a rating lower than 4 stars. High efficacy and desirable skinfeel were the drivers for 5 stars. These findings highlighted the importance of sensory experience and perception of efficacy in consumers’ whole product experience
Report of Progress 1161
Get PDFGrain Sorghum Performance Tests, conducted annually by the Kansas Agricultural Experiment Station, provide farmers, extension workers, and seed industry personnel with unbiased agronomic information on many of the grain sorghum hybrids marketed in the state. Because entry selection and location are voluntary, not all hybrids grown in the state are included in tests, and the same group of hybrids is not grown at all test locations
Extrusion process to retain resistant starch in a pet food for the purpose of altering colonic fermentation end products that benefit dog health
Get PDFDoctor of PhilosophyDepartment of Grain Science and IndustryGreg AldrichStarch that escapes enzymatic digestion in the small intestine is considered resistant (RS). This RS can be fermented by saccharolytic bacteria in the colon and may benefit gut health. Raw crystalline starch granules contain RS type II. Mild extrusion of pet foods may retain some RS II or develop RS type III (retrograded) that may indirectly benefit animal health. The objectives of the present work were to determine the amount of RS present in typical commercial pet foods, develop a response surface model that predicts RS to maximize RS in corn based extruded kibble, produce dog kibbles with three levels of RS based on model criteria, and determine the effects of these diets on dog colonic health, markers of satiety, metabolomics of serum and feces, and fecal microbiome. In commercial dog and cat foods which were either grain-free or grain based (20 total diets) from a sampling frame of 654 pet foods had low RS (average 0.05) by dietary treatments, but dogs fed the MS and LS foods had more indication of saccharolysis, promoted by a higher fecal glucose and oligosaccharides concentration (P < 0.05, q < 0.1). Fecal butyrate concentration increased in dogs fed the LS diet relative to HS, and MS was similar to both extremes (P < 0.05). Diets had no effect on satiety hormones or local immunity, which might suggest the need for a longer feeding period and(or) a diet produced with lower thermomechanical energy for a dietary effect. In conclusion, we suggest a low to mild shear extrusion process to produce corn-based kibbles that may promote gut health
