An Investigation of Preservice Teachers' Understanding of Buoyancy
The purpose of this study was to examine the conceptual understandings of 55 elementary preservice teachers for the concept of buoyancy. This study used Ausubel’s Assimilation Theory (Ausubel, 1963) as a framework for a 15-week intervention that used pre/post concept maps (Cmaps), pre/post face-to-face semi-structured interviews, and drawings as evidences for change of formation of cognitive structures. Using a convergent parallel design and mixed methods approach, preservice teachers’ conceptions were analyzed using these evidences. Results of the study show that preservice teachers held both scientific conceptions and misconceptions about buoyancy as a force before and after an instructional intervention. Of importance were the existence of robust misconceptions about buoyancy that included inaccurate scientific knowledge about the foundational concepts of gravity, weight, mass, and density. The largest gains in scientific knowledge included the concepts of gravity, surface area, opposing forces, and the buoyant force. These concepts were consistently supported with evidence from post-concept maps, post, semi-structured interviews, and drawings. However, high frequencies of misconceptions were associated with these same aforementioned concepts as well as additional misconceptions about buoyancy-related concepts (i.e., weight, density, displacement, and sinking/floating). A paired t test showed a statistically significant difference (t = -3.504, p = .001) in …

Living-learning communities and ethnicity: A study on closing the achievement gap at Regional University
This quasi-experimental study examined the impact of living-learning communities on GPA and fall-to-fall retention rates for college freshmen at Regional University (RU). The specific focus of this study was the effect of these communities on students of different ethnic groups and on the potential of these communities to reduce the academic performance gap. RU was a small public university that offered both undergraduate and graduate degree programs. RU required all freshman students to live on campus in living-learning communities beginning with the 2007-2008 academic year. This study utilized the 343 student freshman cohort class of 2008 in the living-learning communities as the treatment group. This treatment group was compared against the 193 student freshman cohort class of 2008 living off campus and against the 643 student freshman cohort class of 2006 living on campus prior to the implementation of living-learning communities. In addition, the statistics were analyzed by ethnicity to examine the impact of these communities on White, Hispanic, African American, and Native American students and their ability to reduce the academic performance gap. The research revealed that the communities implemented at RU were not statistically significant at improving academic performance or at reducing the achievement gap. The results of …

The Impact of Developmental Stress on Cardiovascular Physiology of Two Archosaur Species: American Alligator (Alligator mississippiensis) and Domestic Chicken (Gallus gallus)
Crocodilians and birds comprise sister taxa of archosaurs, the development of these vertebrates occurs within an egg case that leaves developing embryos susceptible to fluctuations in the nesting environment. Studies suggest that sub-optimal conditions alter morphological growth and cardiovascular physiology. Regulation of the cardiovascular system is immature in the subjects studied, and embryos may rely on humoral rather than neural control of the cardiovascular system. The primary focus of this dissertation was to assess regulatory mechanisms responsible for maintenance of arterial pressure and heart rate. Dehydration stress had marked effects on embryo growth, and altered baseline cardiovascular parameters, while leaving the response to humoral regulator, angiotensin II (Ang II), unaffected. However, dehydrated alligator embryos developed cholinergic tone on heart rate. Hypoxic incubated chicken embryos were reduced in embryo mass, and altered response to humoral regulatory components Ang I and adenosine in addition identifying a novel regulatory component of the cardiovascular response to acute hypoxia. Collectively, these studies add to the existing knowledge of cardiovascular physiology in embryonic archosaurs and suggest that some components of cardiovascular regulation are plastic following developmental stress.

An Examination of the Similarities and Differences Between Transformational and Authentic Leadership and Their Relationship to Followers' Outcomes
To date there is no comprehensive understanding of what leadership is, nor is there an agreement among different theorists on what a good or effective leader should be. The purpose of this dissertation is to examine the theoretical and empirical similarities and differences of two styles of leadership – transformational and authentic leadership. Follower outcomes, as well as, the effects of trust and psychological capital within these paradigms are of particular interest. Although theoretical differences are proposed for the leadership style, the extent of overlap suggests the need to more closely examine each theory. Pilot studies were created to validate original scenarios created for the study as well as to examine the validity and reliability of new measurement instruments. The dissertation is designed to determine whether the relationships between authentic leadership and a variety of follower outcomes including performance, affective commitment, satisfaction, trust, and organizational citizenship behavior are similar to those between transformational leadership and these outcomes. In addition, variables more unique to authentic leadership research including psychological capital and follower well-being were examined within both paradigms to determine whether their relationships are similar to each type of leadership style. An experimental study using Qualtrics was used to collect the …

Cooperative Strategy and Sources of Knowledge Integration Capability and Innovation: A Relational View
Faced with the challenges to addressing the novelties of the changing business environments (e.g., new customer requirement, changes in customers taste and preferences, the introduction of new products or services by competitors), organizations seek to build collaboration among their employees who possess complementary knowledge. Integrating complementary knowledge enhances employees' ability to address environmental challenges and foster innovation. Despite the importance of knowledge integration for innovation, integration of such knowledge becomes difficult when employees lack a shared understanding of knowledge, and when the knowledge is newly generated. Because new knowledge is tacit in nature and highly personal to a particular individual, it is difficult to articulate, making knowledge integration (KI) an arduous task. Lack of shared understanding, the presence of new knowledge, and lack of common interests in employees creates three types of knowledge boundaries – syntactic (information processing) boundaries, semantic (interpretive) boundaries, and pragmatic (political) boundaries. The presence of knowledge boundaries makes it difficult for employees to share and access their knowledge with each other. To overcome the challenges related to the knowledge boundaries, employees use boundary-spanning objects, which are common lexicons, common meaning, and common interests, to share and access their knowledge across the boundaries. Although prior studies have …

Optimization of In Vitro Mammalian Blastocyst Development: Assessment of Culture Conditions, Ovarian Stimulation and Experimental Micro-Manipulation
Factors currently at the forefront of human in vitro fertilization (IVF) that collectively influence treatment success in the form of blastocysts development were investigated during early mammalian embryology with concentration on infertile patients presenting with diminished ovarian reserve or preliminary ovarian failure. A novel experimental technique, Graft Transplant-Embryonic Stem Cells (GT-ESC) was introduced in the mouse model, as the first inclusive approach for embryo selection in IVF treatments resulting in successful graft integration of sibling cells, stage-dependent (day 4) blastocysts. E-Cadherin-catenin bonds play an integral role in trophectoderm cell viability and calcium removal, inducing disruption of cell-to-cell bonds at the blastocyst stage was detrimental to continued blastocyst development. One of the leading methods for embryo selection for uterine transfer in human IVF is application of pre-implantation genetic screening (PGS) methods such as next generation sequencing (NGS). Female patients <35 y do not benefit from this treatment when outcome is measured by presence of fetal heart beats at 10 weeks of gestation. Patients 35-37 y benefit from PGS with no significant difference of outcome based on form of PGS method utilized. Therefore, small nucleotide polymorphism array (snp-array) or targeted-NGS should be selected for this age range to lessen the financial burden …

Predictive Relationships among Learner Characteristics, Academic Involvement, and Doctoral Education Outcomes
The literature identifies multiple factors pertinent to learner characteristics and learning experiences that may promote doctoral education outcomes, and yet little quantitative research has examined relationships between those factors deemed important in the effectiveness of doctoral education. This study sought to examine predictive relationships among doctoral students’ learner characteristics, their involvement in mentorship and intellectual community, and doctoral education outcomes. Using Astin’s theory of involvement and the literature on signature pedagogies in doctoral education as conceptual guides, a survey instrument was constructed for the purpose of measuring variables identified as relevant to the effective formation of scholars. Central to the conceptualization of this study was academic involvement as represented by mentorship and intellectual community. The instrument was validated in a two-stage pilot testing process and administered to doctoral candidates at three public Texas higher education institutions. Of the 217 participants, the majority were female, White (Non-Hispanic), US citizens, and were pursuing education doctorates. Data were analyzed using multivariate statistical analyses. Reliability and validity estimates indicated psychometric integrity of the 20 observed variables measured to represent the constructs of mentorship and intellectual community. Results indicated that doctoral students’ learner characteristics were not notably predictive of doctoral students’ degree of involvement in …

A Quantitative Analysis of the Relationship of a Non-traditional New Student Orientation in an Urban Community College with Student Retention and Grade Point Average Among Ethnic Groups
This quantitative study examined relationships of attending a new student orientation program related to student retention and academic success. A research group of 464 students of Tarrant County College Northwest, a community college campus in Fort Worth, Texas, who voluntarily attended a 2-hour pre-semester new student orientation program was compared to a group of 464 students on the same campus who did not attend the program. Comparisons were made with regard to retention and GPA. Ethnic ratios of both groups are 4% Black, 26% Hispanic, 66% White, and 4% other ethnicities. Chi square data analysis was utilized to determine if statistically significant differences relating to student retention existed between the groups. The independent t-test was used to compare means of calculated GPAs between groups. A one-way ANOVA was used to compare the means of GPAs for ethnic sub-groups. The total group and the Black sub-group showed statistically significant higher levels of second-semester retention (total group p = .018; Black sub-group p = .008) and higher calculated GPAs (total group p = .016; Black sub-group p = .019). No statistically significant results were found among Hispanic students.

The Implementation of a Confidence-based Assessment Tool Within an Aviation Training Program
Traditional use of the multiple-choice question rewards a student for guessing. This technique encourages rote memorization of questions to pass a lengthy exam, and does not promote comprehensive understanding or subject correlation. This begs the question; do we really want question memorizers to operate the machinery of our industrialized society? In an effort to identify guessing on answers during an exam within a safety-critical aviation pilot training course, a qualitative research study was undertaken that introduced a confidence-based element to the end-of-ground-school exam followed by flight simulator sessions. The research goals were twofold, to clearly identify correct guesses and also provide an evidence-based snapshot of aircraft systems knowledge to be used as a formative study aid for the remainder of the course. Pilot and instructor interviews were conducted to gather perceptions and opinions about the effectiveness of the confidence-based assessment tool. The finding of overall positive interview comments confirmed that the pilots and flight instructors successfully used the confidence-based assessments as intended to identify weak knowledge areas and as aids, or plans, for their remaining study time. The study found that if properly trained and administered—especially through a computer-based medium—a robust confidence-based assessment tool would be minimally-burdensome while offering worthwhile …

A Case Study of Tu and Vous Use in the French Dubbing and Subtitling in an American Film
Translation and subtitling has always been a complicated dimension of the motion picture industry for years. The problem of dealing with linguistic elements in films and conveying them to audiences of different languages across the globe encompasses many difficulties regarding forms and structures of other languages. One of the more highly researched topics in French linguistic studies has been the use of address pronouns and a range of aspects related to their use and interpretation. Many studies have been conducted over the last sixty years in order to determine and understand these variables. An analysis of several of these studies reveals the many complexities involved in second-person pronoun choice in the French language and the development of the idea of pronoun choice as an act of social identity. The focus of this study is to provide an analysis of the use of formal and informal address pronoun use in the French subtitling and dubbing of an American film, Maid in Manhattan, in order to add, on a broader level, a way to differentially examine perceived norms in a variety of contexts within this medium.

How Does It Feel to be Creative? A Phenomenological Investigation of the Creative Experience in Kinetic Places
How does it feel to be creative? Such a question, when approached from a phenomenological perspective, reveals new understandings about the embodied experience of creativity, and how it feels as it is being lived. This investigation begins with a provocative contrast of two environments where creativity is thought to manifest itself: school art classrooms, where creativity is often legislated from an authority figure, and New Orleans Second Line parades, where creativity is organically and kinetically expressed. A thorough review of the literature on creativity focuses on education, arts education, creative economies, psychology, and critical theorists, collectively revealing a cognitive bias and striking lack of consideration for community, freedom, and the lived experience of being creative. Further discussions in the literature also neglect sites of creativity, and the impact that place (such as a school classroom) can have upon creativity. The phenomenological perspectives of Merleau-Ponty, Heidegger, Bachelard, and Trigg support a methodological lens to grasp embodied knowledge, perceptions of placedness on creativity, and the interdependent frictions between freedom, authenticity, movement and belonging. The research method includes investigations in New Orleans in archives, examination of visual and material culture, participation in cultural practice, and formal and informal interviews. Further, the phenomena of …

The Effects of the IAM Workshop on Preservice Teachers' Perceptions and Attitudes on Integrating Art and Mathematics In Saudi Arabia
Access:
Use of this item is restricted to the UNT Community
This mixed-methods dissertation used an explanatory sequential design to examine art and mathematics preservice teachers' perceptions and attitudes towards integrating art and mathematics (IAM) after an IAM workshop. The conceptual framework of this study has its basis in three theoretical sources: constructivism, multiple intelligence theory, and semiotics. Each of these sources provides a conceptual lens to examine art integration in the curriculum and the teacher's role in facilitating this instructional process. Participants of this study included two sub-groups at a large university in Saudi Arabia. The first sub-group was preservice teachers of art education. The second sub-group was preservice teachers of mathematics. Quantitative and qualitative results indicated that the IAM workshop had positive impacts on art and mathematics preservice teachers' attitudes and perceptions of IAM. Participants attributed more value to art, were more willing to apply IAM, and felt that there was less barriers for applying IAM. The study also indicated differences between art and mathematics preservice teachers' attitudes towards IAM. The differences were due more to art value than willingness or barriers. After the IAM workshop, mathematics preservice teachers put more emphasis on the importance of art to mathematics, especially with respect to making mathematics a more enjoyable subject.

The Generational Shift: an Exploration of Leadership Behaviors of Senior Student Affairs Officers Through a Generational Lens
The purpose of this quantitative study was to identify and compare differences in leadership behaviors of senior student affairs officers (SSAOs) based on their generational cohort (Baby Boomer, Generation X, Millennial). The Multifactor Leadership Questionnaire (MLQ) was used to measure nine leadership behaviors and three leadership outcomes. Surveys were administered electronically to 3,361 individuals identified as a chief student affairs officer or director of student affairs in the Higher Education Online Directory (2014). The 449 respondents included 246 Baby Boomers, 192 Generation Xers, and 11 Millennials. Due to an uneven sample size, the Millennial group was removed from the data analysis. The total respondents consisted of 215 male and 219 female SSAOs with 260 employed at four-year private institutions and 170 employed at four-year public institutions. A MANOVA was utilized to determine whether or not statistical differences existed between the nine dependent variables (leadership behaviors) and independent group variables (generational group). The findings showed that whereas Generation X SSAOs exhibited more transactional leadership behaviors, Baby Boomer SSAOs were more transformational. The results of this study have implications for the field of student affairs in that research and practice support the need for more transformational leaders in senior administrative positions in …

Teaching First-Semester General Chemistry Using 3D Video Games following an Atoms First Approach to Chemistry
The unified learning model (ULM) focuses on students' engagement, motivation, prior knowledge, and working memory. This study employs the use of video games to assess students' learning through a 3D chemistry gaming environment. In this human-subjects research, students carried out missions and applied reasoning to solve problems appropriate for general chemistry content. For learning to occur, students must be engaged and motivated as stated in the ULM. Learning cannot necessarily be accomplished by experience alone, and critical thinking is required to turn the experience into learning. The interpretation of educational theory applied to video games and this proposed study are discussed. A moderately positive correlation was found between exam score and study time (playing the game). Essentially the more time spent playing the game or an online activity the higher the exam scores. There was an alpha level less than 0.05 (p < 0.05) between the experimental group and non-traditional group (no game or online activity). Supporting that there was a statistically significant difference between groups, the null hypothesis was accepted between the game and online activity. Furthermore, as stated under the ULM, engagement is necessary for optimal learning.

Do Re Mi? Yes! Using Music and Visual Arts to Promote Thai Children's English Vocabulary Development
This research examines the efficacy, if any, of the Music and Visual Arts (MVA) program in improving the English vocabulary development of first grade Thai students. The researcher developed the Vocabulary Recognition Assessment (VRA) as a measure of English vocabulary development. It employs the accuracy and rapidity method of word recognition as a measurement of English language development in Thai children. Forty first grade Thai students in a Bangkok elementary school participated in the study. Participants were divided equally between an experimental group and a control group. During a nine-week period, students in the experimental group were instructed with the MVA strategy, while students in the control group were taught with the Visual Arts (VA) strategy. Paired sample t-test, ANOVA, and ANCOVA were used to analyze data from the VRA, to compare the pre-test and the post-test in terms of accuracy scores and rapidity scores of the control group and the experimental group. Data revealed that students instructed with the MVA strategy improved their English vocabulary development in terms of accuracy of word recognition significantly more than students taught English using the VA strategy. No significant difference was found between the MVA strategy and the VA strategy in terms of …

Use of Digital Fabrication Tools and Curriculum with Gifted Students in Rural Middle Schools
This study focuses on the use of American Invention Kits from the Smithsonian Institute in conjunction with a 3D printer. In conjunction with a large dataset from a study funded by the National Science Foundation (NSF), this innovative research focuses on the effect the digital fabrication curriculum unit has on gifted and talented students' knowledge and affinity toward the fields of science, technology, engineering, and mathematics (STEM). Students from two rural middle schools in north-central Texas (N = 190) took part in this quantitative study; the students were divided among four subgroups: gifted-contrast (n = 12), gifted-treatment (n = 8), nongifted-contrast (n = 76), and nongifted-treatment (n = 94). The surveys utilized include the STEM Semantics Survey, TIMSS-Limited, and a knowledge assessment for the specific curriculum unit focused on the solenoid. The STEM Semantics Survey is divided into five subsets. Thirty-two separate one-way repeated measures ANOVAs were performed across the surveys and subgroups. Statistically significant results were found on four comparisons. This research holds implications in the areas of advocating for gifted education, collecting field data, utilizing large datasets, and understanding rural schools.

Learning From Each Other: Narrative Explorations of Art Museum Self-guided Materials
By engaging in collaborative arts-based and arts-informed narrative inquiry with my six-year-old daughter, we explored self-guided materials in art museums in the North Texas area. Though the field of art museum education is becoming increasingly participatory, most academic research related to self-guided materials has fallen short of exploring visitors' experiences with these materials. Furthermore, the perspectives of children have been long overlooked in academic and, at times, institutional research about family experiences in museums. Over the course of nine months, my daughter and I visited art museums and engaged with their self-guided materials, ranging from audio tours to interactive galleries. During this time we created collaborative works of art based on our experiences, which acted as both data collection and analysis in preparation for writing narratives. Our narrative explorations allowed us each to better understand our collective experiences. Though this research specifically targets self-guided materials in art museums, any educator interested in intergenerational or collaborative family learning may find both our methodologies and our conclusions to be helpful in better understanding how narratives are essential to this type of learning.

Improving Scientific Learning and Supporting Civic Engagement for Undergraduate Non-science Majors
In prior research focusing on teaching and learning science, a definitive trend toward a new approach for undergraduate non-major science courses has emerged. Instruction should be refocused from information-transfer to giving students experiences that allow them to explore and engage in their new knowledge and find ways to integrate it into their everyday lives. One technique is to focus class material on real issues of interest and relevance. Course development that allows for civic engagement and self discovery connects learning to the lives of students and their communities. This study used a quasi-experimental design to see if students who engaged in their learning had improved learning gains, increased motivation, and ability to relate it to their lives. The results showed that students were more motivated to connect the subject to their lives when they engaged through civic engagement projects. Techniques used in this research can be used in the future to develop science courses that focus on the needs of 21st century learners.

Listening to the Freshman Voice: First-year Self-efficacy and College Expectations Based on High School Types
This quantitative study used Astin's I-E-O theory to explore the relationship between a college freshman's high school background and academic self-efficacy. The Beginning College Survey of Student Engagement was used to measure academic self-efficacy across four types of high schools. Student gender and precollege experiences (dual-credit and communication assertiveness) were used as control. A total of 15,400 first-year students were included in this study. An ANOVA was used to examine the differences between groups, and ordinary least-square analysis was used to study the factors that affect academic self-efficacy. Results showed statistically significant difference in academic self-efficacy between public and private religious high school graduates. Specifically, graduates of public high schools had statistically higher academic self-efficacy than graduates of private religious high schools (p < .001). Additionally, females and participants of dual-credit courses also tended to have higher academic self-efficacy. Finally, analysis revealed that a first-year student's communication confidence is highly correlated to their academic self-efficacy. Results confirm in-coming first-year students perceive higher education engagement differently based on traits attributed to their precollege experiences. Results point to criteria colleges may be able to use in identifying freshmen at risk for low academic self-efficacy and, therefore, for problems in retention and degree …

Effectiveness Of Group Activity Play Therapy On Internalizing And Externalizing Behavior Problems Of Preadolescent Orphans In Uganda
This pilot study investigated the impact of group activity play therapy (GAPT) on displaced orphans aged 10 to 12 years living in a large children.s village in Uganda. Teachers and housemothers identified 60 preadolescents exhibiting clinical levels of internalizing and externalizing behavior problems. The participants ethnicity was African and included an equal number of females and males. Participants were randomly assigned to GAPT (n = 30) or reading mentoring (RM; n = 30), which served as an active control. Preadolescents in both treatment groups participated in an average of 16 sessions, twice weekly with each session lasting 50 minutes. Sessions were held in the school located within the village complex. A two (group) by two (repeated measures) split plot ANOVA was used to analyze the data. According to teacher reports using the Teacher Report Form (TRF) and housemother reports using the Child Behavior Checklist (CBCL), children receiving the GAPT intervention demonstrated statistically significant decreases (p < .025) in internalizing behaviors (TRF: p < .001; CBCL: p < .001 ) and externalizing behaviors (TRF: p = .006; CBCL: p < .001) from pretest to posttest compared to children who received RM.

The Effects of a Programmed Teaching Sequence and Response Card Use with Systematic Feedback on the Acquisition of Time Telling Behavior of 3 Students with Intellectual Disability
Few studies have proposed or evaluated methods to teach telling time. The purpose of this study was to evaluate the effects of differential reinforcement of student responding in the form of response cards to teach three middle school students with intellectual disability to tell time. Participants worked through six training phases. Results showed that correct responding increased from pre-assessment (range of 5.71-14.29% correct) to post-assessment (range of 85-100% correct). Preliminary evidence shows promise in the application of these procedures to teach telling time to middle school students with intellectual disability.

The Effects of Fluency-Based Instruction on the Identification of Component Reading Skills
This study examined the effects of fluency-based instruction on the identification of six component-composite relations for early reading skills. Five participants (ages 5-8) who struggled with reading participated. A multiple probe design was used to assess the effects of frequency building on prerequisite skills on the emergence of composite reading skills. The results show that the prerequisite skills taught did not have an effect on the composite skill probes but did have an effect on the assessment scores. The data expand the research pertaining to Precision Teaching, fluency-based instruction, and component-composite relations. These data suggest that additional skills may be needed to be taught in order to effects on the composite skills. In addition, these authors identify the need for the identification of the component skills necessary to teach rapid autonomic naming.

"The Long Goodbye": Uncertainty Management in Alzheimer's Caregivers
Caregivers for individuals diagnosed with Alzheimer's disease (AD) shoulder a remarkably complex burden as compared to other caregivers of elderly individuals. For long distance caregivers, geographical separation further compounds the problems experienced by AD caregivers, as they are isolated from family members and support networks. Both on-site and long-distance AD caregivers experience uncertainty; the findings from this study illustrate how AD caregivers manage the uncertainty of the disease and primary care, as well as how uncertainty differs between on-site and long-distance caregivers. AD caregiver (N = 13) interviews were transcribed and qualitatively analyzed using uncertainty management theory as a thematic lens. The analysis revealed that AD caregivers experience overwhelming feelings of burden, guilt, and doubt; however, these feelings manifest differently depending on caregiver type. The findings of this study demonstrate that sources for obtaining information regarding AD and caregiving were useful for on-site caregivers; however, the sources did not account for the needs of long-distance caregivers or the psychosocial needs of on-site caregivers. Furthermore, AD caregivers did not seek support or information about AD and caregiving from health care professionals. Implications for future research regarding long-distance and on-site AD caregiving are discussed.

A Century of Overproduction in American Agriculture
American agriculture in the twentieth century underwent immense transformations. The triumphs in agriculture are emblematic of post-war American progress and expansion but do not accurately depict the evolution of American agriculture throughout an entire century of agricultural depression and economic failure. Some characteristics of this evolution are unprecedented efficiency in terms of output per capita, rapid industrialization and mechanization, the gradual slip of agriculture's portion of GNP, and an exodus of millions of farmers from agriculture leading to fewer and larger farms. The purpose of this thesis is to provide an environmental history and political ecology of overproduction, which has lead to constant surpluses, federal price and subsidy intervention, and environmental concerns about sustainability and food safety. This project explores the political economy of output maximization during these years, roughly from WWI through the present, studying various environmental, economic, and social effects of overproduction and output maximization. The complex eco system of modern agriculture is heavily impacted by the political and economic systems in which it is intrinsically embedded, obfuscating hopes of food and agricultural reforms on many different levels. Overproduction and surplus are central to modern agriculture and to the food that has fueled American bodies for decades. Studying …
