Sociocognitive and socioemotive factors associated with early academic abilities in preschool children in Costa Rica
Authors:   , Conejo Bolanos L. Diego
Published: December 2023

This study aims at providing a multi-report, multi-method model of academic and socio-emotional preparation in preschool children that integrates bodies of previous research that have been conducted primarily in isolation. The main purpose is to test a comprehensive model of self-regulation and its links to moral reasoning, prosocial behaviors and early academic abilities. Participants were 193 Costa Rican preschool children for whom parent- and teacher- reports were collected. Also, children were evaluated with performance tests. The results showed that self-regulation is better represented as a bifactorial model with both cognitive and emotional components. Also, the study showed evidence suggesting that prosocial behaviors in preschoolers are better explained as a multidimensional construct rather than a unidimensional variable. Cognitive self-regulation showed positive links with prosocial moral reasoning, prosocial behaviors and early academic abilities, whereas emotion regulation showed only significant relations with prosocial behaviors. The relations between self-regulation and early academic abilities were direct and not mediated by prosocial moral reasoning or prosocial behaviors. The results are discussed in light of previous findings, and some implications for theories of human development and future interventions are presented.
Mechanisms for chlorinated lipids in sepsis
Authors:   , Yu Hong
Published: December 2023

Sepsis induces the formation of proinflammatory chlorinated lipids, stimulates adhesive interactions between the endothelium and leukocytes/platelets, causes mast cell activation, disrupts the microvascular barrier and causes acute lung injury. Using a cecal ligation and puncture (CLP) model of polymicrobial sepsis, the aims of this study were to determine whether: 1) the proinflammatory responses to sepsis are instigated by myeloperoxidase (MPO), an enzyme that produces hypochlorous acid, which can attack membrane plasmalogens to produce chlorinated lipids, 2) MPO plays an important role in the generation of cytokines and chemokines that have been proposed as mediators of the inflammatory responses to sepsis, and 3) plasminogen-activator inhibitor-1 (PAI-1) and mast cells contribute to CLP-induced adhesive interactions between leukocytes/platelets and the endothelium. A subproject to Aim 3 sought to identify the contribution of PAI-1 and mast cells to adhesive interactions induced by chlorinated lipids in lieu of CLP, as an approach to support the concept that MPO-derived chlorinated lipids may serve as an important mediator of sepsis-induced inflammatory responses. Our results are consistent with the concept the CLP promotes MPO-dependent release of proinflammatory PAI-1, cytokines, and chemokines, which in turn activate mast cells to elicit leukocyte/platelet adhesive interactions with the endothelium, neutrophil migration into the tissues and disruption of microvascular barrier function.
Adaptive apparel advocacy : a case study exploring how Mindy Scheier catalyzed the adaptive apparel market
Authors:   , McBee-Black Kerri
Published: December 2023

The purpose of this study is to gain an in-depth, holistic, and contextualized understanding of how Mindy Scheier catalyzed the adaptive apparel market by exploring her role as an adaptive apparel advocate and her collaboration with Tommy Hilfiger(R), to launch a first-of-its-kind adaptive apparel line, Tommy Adaptive. The recent interest of apparel brands to embrace the PLWD consumer suggests a possible shift in the apparel industry toward an inclusive approach to fashion. A single, main case study design was used to examine the phenomenon. The study found that Scheier was motivated to become an advocate for the adaptive apparel market by the apparel needs and challenges of her son. This motivation led Scheier to engage in an in-depth consumer market and design innovation research to gain knowledge of the apparel needs and challenges of PLWD. This knowledge led to a collaboration with a supply chain partner, which led to the first-of-its-kind mainstream fashion-forward adaptive apparel line with Tommy Hilfiger(R). The study also found that Scheier sacrificed her career goals, her income, and her dignity to ensure adaptive apparel went mainstream in the apparel industry. The study's findings have contributions to the Social Model of Disability, MRCS, R-A, and GSCM theory and implications for apparel brands and entrepreneurs wishing to enter the adaptive apparel market as well as for policymakers, and apparel researchers.
The time-dependent response of concrete bond to steel under high sustained loads
Authors:   , Swoboda Philip
Published: December 2023

Design errors, poor construction practices, material deterioration, and other issues can lead to reinforced concrete members being subjected to levels of sustained stresses higher than their expected service loads. These high levels of sustained stress have led to catastrophic RC building collapses around the world. Loading a member greater than 0.75fc' is referred to as high sustained loading and is in the range that could potentially lead to the progressive collapse of a structure. Unfortunately, the behavior of concrete members under this loading condition is not well understood. By gaining understanding of member's behavior when loaded under high sustained stresses, future engineers can better identify elements nearing failure. Preliminary tests performed on simple RC beams tested in flexure showed the beams' tendency to increase in deflection with time--more than the expected creep deflection. This extra deflection occurring at high sustained loading may be accounted for by slippage between the reinforcing bar and the concrete. In order to isolate and study this bond slippage under high sustained loads, beam-end bond tests were loaded to 85-90 [percent] of their short-term capacity and observed for several weeks. The tests show that continued slipping is occurring under high sustained loads. The first sustained load test experienced 22 of its overall slip when under sustained load. The first sustained test also withheld a bond load of 12 [percent] more than the control specimens. The three sustained specimens experienced an increase in free end slip from 0.001" to 0.00254" under constant load which is 90 [percent] to 230 [percent] of the slip at failure in the control specimen. This slip under high levels of sustained load may contribute to the additional deflection under sustained load in reinforced concrete members.
Anchor team gender make-up and audience evaluation
Authors:   , Ninke Kathleen Witte
Published: December 2023

For decades, the man-woman anchor team has been the industry standard in both national and local news. Recently, high-profile national newscasts have used two anchors of the same gender to headline the broadcast. In local news, while scientific data is not available, the standard seems to remain: newsroom managers generally hire for a man-woman newscast. However, per this experimental study, audiences do not prefer the man-woman team over the man-man or woman-woman team with any statistical significance. Furthermore, audiences rated a two-woman team more "credible" than its counterparts. This research explores the heuristics and socialization that may inform an audience member's evaluation of a newscast and its anchor team while questioning the mixed-gender standard.
Influence of supervised activity zones during recess on sedentary activity, social skill development, and problem behavior in elementary-aged children
Authors:   , Barnas Jillian L.
Published: December 2023

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Due to the childhood obesity epidemic, many school-based interventions have been developed to target physical inactivity before it develops in their adult years. However, due to the heightened importance on academic achievements, many schools have reduced opportunities for children to engage in physical activity (PA) to lessen negative behaviors. PURPOSE: This study compared changes in PA, social skills, and problem behaviors in youth with supervised and unsupervised activity-zone playgrounds (AZP) during school recess. METHODS:143 third-, fourth-, and fifth-grade boys and girls from two elementary institutions had their PA measured using Actigraph-GT3X accelerometers for a total four weeks. Baseline data were collected for one week prior to activity zoning. Afterwards, the playgrounds were divided into six activity zones for two weeks, with activity zones supervised at only one institution. Activity zones were removed, and PA data were collected for one-week post intervention. Educators completed the Social Skills Improvement System pre- and post-intervention which measured social skills, problem behaviors, and academic competence. RESULTS: Few differences were seen in PA engagement and behavior between the supervised and unsupervised conditions throughout the duration of AZP implementation. Initial activity status affected PA engagement that occurred with AZP implementation such that reductions in vigorous PA and increases in light PA were detected among active students (p [less than] .05) with no changes among inactive students. Increases in moderate-to-vigorous physical activity (MVPA) with subsequent decreases in sedentary activity during recess were noted for third grade students in addition to improvements in their social skill scores by 3 [percent] (p = .003). Fifth grade students showed no significant change in PA engagement or behavior during the intervention. No differences in problem behaviors or academic competence were detected (ps [greater than] .05). CONCLUSION: AZPs during recess can improve PA engagement and can lead to improvements in school day behavior, especially in younger students. Supervising AZPs may be detrimental to PA engagement during recess, however, this is may be dependent on the reliability of employed supervisors. Additionally, considerable attention is needed with regards to developing activities that will appease students of differing activity statuses, older students, and that will prevent a decrease in higher intensity PA engagement.
Three essays on economics of education
Authors:   , An Yang
Published: December 2023

This dissertation includes three chapters. In Chapter 1, I estimate the effects of gender and race/ethnicity matching between students and high school math and science teachers on students' STEM enrollment and completion in colleges. My sample includes over 100,000 Missouri high school graduates entering a four-year public university in Missouri between 2001 and 2010. Potential bias from non-random teacher-student sorting within and across high schools is mitigated by examining student exposure to teaching staff broadly, and the use of within-high school variation for identification. I find no evidence of matching effects on students' postsecondary STEM outcomes. My findings for gender matching are more precise than for race/ethnicity and rule out modestly positive impacts. In Chapter 2, I estimate the effects of nursing articulation agreements between the University of Missouri-Columbia (MU) and numerous public community colleges on the likelihood that community college students transfer to the MU four-year nursing degree program. I use difference-in-differences specifications that leverage variation in the availability of nursing articulation agreements with MU across community colleges and over time to identify the effects of these agreements. I supplement these models with triple-difference specifications that additionally leverage variation in transfer rates across initial majors in community colleges. I find no statistical evidence that nursing articulation agreements affect student transfer rates. Supplementary analyses indicate that my null findings are not driven by supply constraints in the MU nursing program and instead reflect the failure of the articulation agreements to spur demand for nursing education among community college students. In Chapter 3, we examine how teachers from two alternative preparation programs--Teach for America (TFA) and Kansas City Teacher Residency (KCTR)--contribute to the teacher labor market in and around Kansas City, Missouri. We show that TFA and KCTR teachers are more likely than other teachers to work in charter schools, and more broadly, in schools with high concentrations of low-income, low-performing, and underrepresented minority (Black and Hispanic) students. TFA and KCTR teachers are themselves more racially/ethnically diverse than the larger local-area teaching workforce, but only KCTR teachers are more diverse than teachers in the same districts in which they work. In math in grades 4-8, we find sizeable, positive impacts of TFA and KCTR teachers on test-score growth relative to non-program teachers. We also estimate positive impacts on test-score growth in English Language Arts (ELA) for teachers from both programs, but our ELA estimates are smaller in magnitude.
The spirit of exhibition and visual pedagogy in the work of Charles and Ray Eames
Authors:   , Bradley Lorinda Roorda
Published: December 2023

This project examines the ways in which Charles and Ray Eames promoted visual pedagogy in their exhibitions and new media experiments. Through cooperative efforts with various artists, designers, educators, scholars, museums, corporations, and institutions, the Eameses refined methods of visual communication to create effective experiential learning spaces. Within these spaces, the Eameses developed strategies that sought to unite art, science, and technology as well as underline the value of visual literacy within the new media landscape. By analyzing the Eameses' collaborations, interdisciplinary educational initiatives, exhibition designs, multimedia presentations, and didactic films, I reveal the ways in which the designers constructed pedagogical environments through the experimental use of new media. This dissertation seeks to ground Charles and Ray Eames in their historical moment, illustrating the ways in which the Eameses' work anticipated, engaged, and reflected contemporary theoretical developments in vision, media, and interdisciplinary education. The Eameses believed new media had the potential to dissolve the artificial categorization of academic disciplines: film could be used to teach mathematics; toys could provide insight into fine art; and technology could help to create a visually literate populace. Consequently, the Eameses combined traditional display models and new media in highly choreographed spaces that relied on objects and images to communicate cultural histories, ideas, and values.
Analytical earth-aerocapture guidance
Authors:   , Cihan Ibrahim Halil
Published: December 2023

Aerocapture is a technique of employing a single atmospheric pass to inserts a spacecraft from a hyperbolic orbit, approaching from deep space, into an elliptical (captured) orbit around its destination planet. After atmospheric flight and energy dissipation, propulsive maneuvers are needed to be performed to place the spacecraft in a target orbit. The exo-atmospheric propulsive maneuvers require much less propellant consumption compared to conventional orbit capture methods. This research aims to develop a new analytical predictor-corrector (APC) guidance method for the Earth-aerocapture problem in order to provide near-optimal performance in terms of exo-atmopheric velocity impulses required to establish the desired target orbit. The optimal aerocapture problem is analyzed using the bang-bang bank control structure. This thesis presents a bank-modulation APC guidance algorithm consisting of two phases: descent phase (lift-up) and ascent phase (lift-down) to mimic the optimal bang-bang bank angle structure. The APC guidance relies on open-loop and closed-loop bank control laws during the descent and ascent phases, respectively. Using the parameterizations of the aerodynamic acceleration effects and the flight-path angle term as a function of altitude, a closed-form expression of atmospheric exit velocity is obtained. Two separate scenarios (Fourier curve fitting and exponential curve fitting) are implemented to parameterize the aerodynamic acceleration effects, while the flight-path angle is parameterized with a single term exponential function. After the bank-switching (from open-loop to closed-loop control) is reached, the bank angle is continuously commanded in the ascent phase to track the reference flight-path angle profile and achieve desired exit conditions. A bank-reversal logic is developed to minimize the difference between the inclination of the post-atmospheric orbit and the desired target inclination. Using large dispersions in the vehicle parameters, entry state, and atmospheric density, Monte-Carlo simulations are executed to test the performance and robustness of the proposed APC guidance algorithm. The simulation results reveal that the well-developed APC guidance algorithm provides the robustness and near-optimal performance.
Biophysical modeling to reverse engineer two mammalian neural circuits lower urinar Y tract and hippocampus
Authors:   , Guntu Vinay Sandeep Kumar
Published: December 2023

Computational neuroscience provides tools to abstract and generalize principles of neuronal function using mathematics and computers. This dissertation reports biophysical modeling approaches to facilitate reverse engineering of two mammalian neural circuits - the lower urinary tract for the development of stimulation techniques, and the rodent hippocampus to understand mechanisms involved in theta rhythms. The LUT in mammals consists of the urinary bladder, external urethral sphincter (EUS) and the urethra. Control of the LUT is achieved via a neural circuit which integrates distinct components. Dysfunctions of the lower urinary tract (LUT) are caused by a variety of factors including spinal cord injury and diabetes. Our model builds on previous models by using biologically realistic spiking neurons to reproduce neural control of the LUT in both normal function and dysfunction cases. The hippocampus has long been implicated in memory storage and retrieval. Also, hippocampal theta oscillations (4-12 Hz) are consistently recorded during memory tasks and spatial navigation. Previous model revealed five distinct theta generators. The present study extends the work by probing deeper into the intrinsic theta mechanisms via characterizing the mechanisms as being resonant, i.e., inherently produce theta, or synchronizing, i.e., promote coordinated activity, or possibly both. The role of the neuromodulatory state is also investigated.
Application of electronic structure calculations to vibrational spectroscopy and gas encapsulation in zeolites
Authors:   , Mofrad Amir Mehdi
Published: December 2023

Zeolites are an important class of aluminosilicate materials that have wide applications in heterogeneous catalysis, gas separations, and ion-exchange processes at industrial scales. The desire to continue doing research on zeolites and zeolitic materials continues to be strong for two reasons: (i) to discover new zeolites with unique framework structures and (ii) to modify existing zeolites to discover new functionalities for applications that utilize zeolites. These goals require extensive use of characterization techniques, which can be expensive and heavily reliant on conjecture or supposition. Thanks to the advancement of computational power as well as improved numerical algorithms, theoretical studies of zeolites have become a powerful and complementary tool in the zeolite science community over the last few decades. This dissertation uses computational techniques to aid in the characterization and analysis of zeolites. We first investigate the vibrational properties (i.e., infrared and Raman spectra) of sodalites, including sodalites that have been ion exchanged, by means of density functional theory (DFT) calculations. The resulting spectra serve as a reference for scientists (either experimentalists or theoreticians) in the zeolite community and guide future experimental efforts but might not be sensitive enough for quantitative measurements of ion-exchange levels. We then use DFT and the nudged elastic band method to investigate the rate of release of 85Kr from zeolites used to encapsulate radioactive krypton. Results from our theoretical analysis reveal that although zeolites should entrap 85Kr, they might not entrap the decay product, corrosive 85Rb. These findings lead to interpretations and conclusions that are diffcult if not impossible to acquire experimentally.
Anisotropy and mantle flow of the Indo-Burma subduction zone from shear wave splitting and shear wave splitting tomography
Authors:   , Islam Md Mohimanul
Published: December 2023

The Indo-Burma subduction zone lies on the eastern boundary of the 1500 km long Alpine-Himalayan orogenic belt. Despite highly oblique plate motion with limited arc development, convergence is still ongoing with the potential to generate megathrust earthquakes that could affect more than 140 million people. This sub-aerial subduction system provides an excellent opportunity to study the nature of mantle deformational fabric resulting from the active convergence and collision with possible clockwise rotation of the Indian plate. Characterizing the mantle flow field helps us to better understanding the geodynamics and regional tectonics of this part of the plate boundary. Shear wave splitting is a simple yet powerful technique to investigate anisotropy and mantle strain fabric. I have used both teleseismic and local shear waves to create a detailed map of the upper mantle anisotropic fabrics using a recently deployed temporary and permanent seismic stations, across the northern and central parts of Myanmar. Along with the detailed analysis of splitting parameters, I have generated a tomographic model inverting local and teleseismic shear waves splitting results. The resulting 3D anisotropic model helps to image the prevailing mantle flow below the slab in the sub-slab region and above the slab in the mantle wedge. I found a trench parallel fast direction with high lag time (>2.0s) on the fore-arc that primarily accumulated in the sub-slab region. Such observed fabric results from the toroidal flow around the slab in response to the slab roll-back. The mantle wedge shows a complex deformational fabric with an average lag time of over 0.5s. Dextral motion along the Sagaing fault induces a dominant trench parallel fabric on the mantle wedge. Null results in the southern part of the Shan plateau suggest that back-arc upwelling may exist between the transition of the east-west fast direction on the southern Yunnan and the north-south fast direction of the western subduction margin. The nature of the transition of the mantle fabric and back-arc upwelling is not well understood due to the lack of seismic station coverage on the Shan plateau.
Rapid detection of pesticide residues in foods using surface-enhanced raman spectroscopy coupled with gold nanostars
Authors:   , Lin Min-Hui
Published: December 2023

Constant monitoring pesticide residues in foods is an essential part of food safety. In recent years, there is a growing concern about food issues in agricultural products. Tradition testing methods such as high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) demand time-consuming sample preparations and well-trained operators. Therefore, this research aimed to establish a novel, simple, and rapid testing technique. In this study, the SERS performance of gold nanostars was evaluated by detecting two commonly used pesticides, thiabendazole (TBZ) and paraquat in the real food samples. Gold nanostars were used as a surface-enhanced Raman spectroscopy (SERS) substrate due to their highly branched structure, which provide many SERS hot spots for generating intensified Raman signals from the target analytes. Additionally, the rough topography of gold nanostars has large surface area, which can enable good interactions between the substrate and analyte molecules. The UV-vis spectrometer, electron microscopes and Zetasizer were utilized for characterization. The detection limits of this SERS method are 5 ppm for TBZ in apple juice and 0.2 ppm for paraquat in green tea. These results indicate that SERS coupled with gold nanostars is a facile approach and has great potential to be applied for qualification and quantification of trace contaminants in foods.
Exploring factors associated with free and reduced-price lunch participation in Missouri school districts
Authors:   , Mangoni Gloria Ndindir
Published: December 2023

Participation in school meal programs is critical for meeting the most vulnerable children's daily food requirements while allowing School Food Authorities to get reimbursed for the meal provided and thus continue to run the program in their local entities. The analysis of the Department of Elementary and Secondary Education data during the last decade revealed a 10.3 percent in the number of reimbursable lunches served in Missouri, with a lower participation level of eligible students from southern lower-income counties compared to Northern counties during the 2018-2019 school year. Previous studies on school lunch participation have shown that students' socio-demographic and socio-economic characteristics, the school's geographical location, and policies implemented at the school, state, or federal level affect students' participation in the program. This research examines the extent to which school districts' place-based variables such as geographical location, implementation of Community Eligibility Provision, as well as socio-economic and demographic variables (proportion of children in poverty, household income, school district size, age, race, gender, household head marital status and English proficiency) influence school districts' levels of participation in Free or Reduced-price lunch in Missouri. To assess the significance of the association of school districts' place-based characteristics, a Generalized linear model was estimated based on cross-sectional data of Free and Reduced-price lunch from the 2018-2019 school year, and the five-year estimates of socio-economic and demographic (2013-2017 American Community Survey data). The findings suggest that economic and demographic factors such as household income, children poverty, school district size, age, and the proportions of single female-headed households and non-English proficient households significantly influenced school districts' rates of participating in Free or Reduced-price lunch participation in Missouri. However, the school district level of analysis hindered observing the effects of other variables that may be significant at a lower scale of analysis, especially gender and race. An increase of the sampling frame and the use longitudinal data will help better capture the association of school districts' demographic predictors with Free and Reduced-price lunch participation. With the recent outbreak of the COVID-19 pandemic and the subsequent school closure, future studies can also explore the effects of this public health issue on Free and Reduced-price lunch participation.
Consortium blockchain management with a peer reputation system for critical information sharing
Authors:   , Purohit Soumya
Published: December 2023

Blockchain technology based applications are emerging to establish distributed trust amongst organizations who want to share critical information for mutual benefit amongst their peers. There is a growing need for consortium based blockchain schemes that avoid issues such as false reporting and free riding that impact cooperative behavior between multiple domains/entities. Specifically, customizable mechanisms need to be developed to setup and manage consortiums with economic models and cloud-based data storage schemes to suit various application requirements. In this MS Thesis, we address the above issues by proposing a novel consortium blockchain architecture and related protocols that allow critical information sharing using a reputation system that manages co-operation amongst peers using off-chain cloud data storage and on-chain transaction records. We show the effectiveness of our consortium blockchain management approach for two use cases: (i) threat information sharing for cyber defense collaboration system viz., DefenseChain, and (ii) protected data sharing in healthcare information system viz., HonestChain. DefenseChain features a consortium Blockchain architecture to obtain threat data and select suitable peers to help with cyber attack (e.g., DDoS, Advance Persistent Threat, Cryptojacking) detection and mitigation. As part of DefenseChain, we propose a novel economic model for creation and sustenance of the consortium with peers through a reputation estimation scheme that uses 'Quality of Detection' and 'Quality of Mitigation' metrics. Similarly, HonestChain features a consortium Blockchain architecture to allow protected data sharing between multiple domains/entities (e.g., health data service providers, hospitals and research labs) with incentives and in a standards-compliant manner (e.g., HIPAA, common data model) to enable predictive healthcare analytics. Using an OpenCloud testbed with configurations with Hyperledger Composer as well as a simulation setup, our evaluation experiments for DefenseChain and HonestChain show that our reputation system outperforms state-of-the-art solutions and our consortium blockchain approach is highly scalable
Behind human faces : how exemplars experience the news process
Authors:   , Allison Alexis
Published: December 2023

Journalists often seek to put a "human face" on a systemic issue. The resulting source is an exemplar, or person whose story serves to illustrate a greater phenomenon. Journalism scholarship has examined why and how journalists choose exemplars, as well as how their inclusion in a story affects readers and viewers. But what's it like to be the exemplar? Through six in-depth interviews with people recently featured in the news, this study explores how exemplars experience the news process, from connecting with a journalist to reading about themselves in a published story; and how exemplars talk about journalists and journalism afterward. In the end, I argue that the journalist-exemplar relationship is unique among relationships the journalist forges with other sources. The vulnerability experienced by the exemplar, coupled with the value they place on the relationship both as a means to an end and an end in itself, merits extra care from the journalist.
Differential observing responses: a systematic review
Authors:   , Kirlin Landon Allen
Published: December 2023

Some individuals with autism spectrum disorder (ASD) respond inaccurately on conditional discrimination tasks involving matching to sample procedures (MTS). Differential observing responses (DOR) have been effective at increasing discriminated responding of relevant features of stimuli on these tasks (Farber, Dickson, and Dube, 2017). However, there is conflicting evidence of successful conditional discrimination when this procedure has been removed and the longer-term implications of this procedure are unknown (Walpole, Roscoe, and Dube, 2007). The purpose of the current review was to evaluate previous research investigating the effects of DOR procedures in learners with ASD and other developmental disabilities. Fifteen articles were included, and results indicated expressive DOR procedures more commonly maintained accurate responding relative to receptive DORs. Furthermore, only five of the articles selected met high quality standards.
The pleasure-pain motif in the poetry of John Keats
Authors:   , Dunham Larry Dean
Published: December 2023

This study is intended to show that one of the commonly noted motifs in the poetry of Keats is also a feature of considerable importance. The swift interchange of pleasure and pain or the ability of the poet to be happy and sad in the same instant are often acknowledged to be among the qualities of Romanticism. What Keats does with these conventional motifs is worth noting, and how he develops the motif in a subtle interplay of moods is clearly related to the design of some of his greatest works. The text I have used, except where noted, is that of H. W. Garrod, The Poetical Works of John Keats, 2nd ed. (London: Oxford University Press, 1958). I am deeply indebted to Dr. Charles M. Hudson and Dr. Howard Hinkel for their inspiration and guidance. I am especially grateful to Dr. Hudson, who suggested the topic and has been very generous with his time and books. My conversations with him through the past several years have always been enlightening and sometimes even therapeutic. Dr. Hinkel's impressive knowledge of Keats and careful reading of the text have been invaluable. My wife, Martha, deserves the largest share of thanks. For her constant support and encouragement, I can never adequately express my gratitude--at least on paper.
A monograph of Lupinus for Argentina
Authors:   , Planchuelo Ana Maria
Published: December 2023

The species of Lupinus for Argentina are reviewed in a morphological and taxonomic study. For the country of Argentina and vicinity there were 85 species cited. Over 45 holotypes, numerous isotypes and several non-type materials were studied in detail. A photograph of herbarium specimens and the dissection of flowers were made for each type specimen. After a critical evaluation of each species a list of synonyms was proposed for several taxa. The initial number of species was reduced to 29 species and three varieties. Only seven names of the 85 epithets cited have not been treated since it was not possible to verify these with the type material. A taxonomic key for the identification of each taxon was made on the basis of vegetative and floral characteristics. A detailed description of the genus, and each species is presented along with photographs of specimens and enlargements of flower dissections. For some species line drawings were also prepared. The work is completed with a critical review of the taxonomic position of the family and genus. The economic importance of the genus is also discussed. The principal phytogeographic features of Argentina are discussed in a special chapter a long with the ecological adaptability of the species studied.
The nature of nothingness in King Lear
Authors:   , Summers Jon L.
Published: December 2023

"The approach toward life in the sixteenth century was paradoxical. Writers and thinkers struggled with the questions and problems of life; they tried to determine if life had any value, and if it consisted of something. The prospect of nothingness and the void loomed large on the intellectual horizon. Something versus nothing was the dominant intellectual conflict or tension in the sixteenth century. Beneath this dominant tension were more specific tensions. Man was concerned with the issue of belief versus unbelief. The order of man's universe was in danger of being replaced with chaos. Permanence was giving way to flux, and the result was often a loss of certainty with an increase of uncertainty. Consequently, man's feeling of security gave way to insecurity, and his feeling of significance was in danger of being eroded and replaced by a profound feeling of insignificance. In many instances, independence gave way to dependence, and the objective approach to the world was constantly being challenged by a subjective approach. Rationality was perpetually under attack by irrationality, and idealism was continually coming into conflict with realism. Frequently man would shift his emphasis from life to questions about death, and his optimism often dissolved into pessimism."--Chapter 1.

A rapid helium mass spectrometry leak detection method is established to respond to problems of low sensitivity and efficiency in detecting leaks in large vessels. The optimized multistage tandem leak detection system improves leak detection sensitivity by increasing the amount of gas entering the analysis chamber. By involving the main pumping system in the detection process, the effective pumping speed is increased, resulting in a significant reduction in system response time. Additionally, the optimal leak detection vacuum required for maximizing the leak velocity indicating gas movement is determined, thereby further decreasing the system’s response time. Our application demonstrates that the optimized leak detection system increases sensitivity by one to two orders of magnitude, reduces system response time by over 90%, and shortens evacuation time by 7 h. Ultimately, the optimized design of the vacuum system developed for large vessels demonstrates greatly improved leak detection efficiency and overall capability.
ON THE SEARCH OF NEW AESTHETICS IN CONTEMPORARY UKRAINIAN LITERATURE (BASED ON THE NOVELS OF MAKSYM DUPESHKO)
Authors: Vardevanian Svitlana
Published: December 2023

Modern Ukrainian literature reacts to the collapse of the postmodern project and the emergence of a new cultural logic - metamodernism. This article is an attempt to prove it on the example of an analysis of the work of a modern Ukrainian writer. Maksym Dupeshko’s novels «The Story Worth an Entire Apple Orchard» [Istoriia varta tsiloho yablunevoho sadu] (2017) and «Near the Carriage under a Dead Fox» [Bilia karety pid mertvym lysom] (2021) served as the artistic material for the study. A scrupulous analysis of the novels testifies to the writer’s sensitivity to tectonic shifts in modern aesthetics. Both novels work with the phenomenon of the influence of historical memory on the present. And the strategies used by the author fully illustrate the theses of metamodernism theorists: oscillation between pre-modern, modern, and post-modern practices; fragmented «I» and attempts to integrate it into newmeaningful configurations; finding the multiplicity of human subjectivity; transition from parataxis to metaxy; a movement from melancholy to hope. Maksym Dupeshko’s texts testify listening to a new sensuality. The writer is not afraid to search for the truth, to be simple (both at the level of language and at the level of transmitted ideas), he consciously uses banality, he is deliberately pathetic, oscillates from irony to seriousness, from naivety to sincerity, always, however, without approaching cynicism. «The Story Worth an Entire Apple Orchard» is a novel-reflex on the modern Russian-Ukrainian war. The credit of the novel is that in its area there is a very important for our literature a change of modes in the artistic interpretation of reality — a transition from the obvious to the significant, after that we will no longer be ashamed to be heroes, to be from the provinces, to seek God and places of strength, we willstop confusing naivety and sincerity. «Near the Carriage under the Dead Fox» is a novel-anamorphosis - a construction that seems absurd to us if we look at it directly, but when we change the angle of view, it acquires clear and recognizable outlines. This novel engages the reader in the quest, it demonstrates a way to look into our modern existence - an endless chaos of things, events, ideas, aesthetics, fragments of sleeps, fragments of destinies, parts of dreams, hallucinations and fantasies.
PINK FLOYD’S «THE RED VIBURNUM IN THE MEADOW»: A NOVEL IN THE SCORE
Authors: Gon Oleksandr
Published: December 2023

The paper explores the design and structure of Pink Floyd’s single «Hey Hey Rise Up» in terms of a patterned plot in a work of fiction. The music and video of the single are contextualized in the field of comparative studies and problematized as a feasible intersemiotic approach to musical narrativity. The introduction by the folk choir in the video functions as the exposition to the main theme, and its break on D-sharp with the fermata functions as the tense suspense in a frustrated anticipation of the resolution into the tonic of C-sharp minor. Following a two-beat rest, the dignified drums propel the syntax of the story of Ukraine’s heroic resistance against the Russian aggression into the structured artistic plot. Based on the pentatonic scale, David Gilmour’s guitar solo emblematizes other components of both literal and literary dramatic conflict: the highest notes represent the semanticized rising action leading to a “blue note” of F double-sharp that signifies the tension and climax in the musical plot. Gilmore’s musico-teleological tale ends with a descending scale that seems to be the equivalent to the falling action in drama, and finally resolves into a half, rather than full, cadence in G-sharp as if to suggest an open, brighter and victorious finale of yet-to-come resolution of the Russia-Ukraine war. A close musicological reading of the functioning of the harmonic sequences of cadences and the specifics of voice leading in the single reveals the musical artistic means of generating deep meanings and emotional understanding of history. Interpreted through the prism of intersemiotic scheme as emplotmet, the musical narrative has the attributes of a literary work - the beginning, development and suspense of the action, climax of dramatic conflict and its denouement. The paradigmatic affinity of narrative techniques in fiction and music brings new urgency to such fundamental ideas as Borgesian four invariant stories, which are recycled in various historical and ideological guises, or Bakhtinian distinction between the epic and the novel as a territory of encounter with the unfinished present, which expands the optics of reading the dynamics of consonant and dissonant intervals in the blues scale, and turns the music score into a novel. And vice versa: the function of the blue note in the pentatonic, bright and perfectly consonant five-step system without chromaticism, compels us to revisit Nietzsche and his philosophico-musical revelation about the interdependence of Apollo and Dionysus.
