Comparing The Effects of Sulfur-Synthetic Fungicide Mixtures On Leaf Spot And Rust Peanut Pathogens
No full textEarly and late leaf spot, caused by the fungi Passalora arachidicola and Nothopassalora personata, are important foliar diseases of peanut that can lead to premature defoliation and yield loss if not controlled. In fields with a history of leaf spot, the diseases are managed using frequent applications of fungicides. Recently, mixtures of micronized elemental sulfur with tebuconazole, a demethylation inhibitor (DMI) fungicide, or azoxystrobin, a quinone outside inhibitor (QOI) fungicide, were shown to lessen defoliation caused by leaf spot. The objective of this study was to determine if sulfur mixtures reduce defoliation by causing fewer leaf spot infections or by increasing plant tolerance. Field studies conducted at the University of Georgia Coastal Plain Experiment Station in 2020 and 2021 exposed peanut plants to 7 applications of six fungicide treatments at recommended rates: (1) a nontreated control, (2) sulfur, (3) tebuconazole (DMI), (4) DMI + sulfur, (5) axozystrobin (QoI), and (6) QoI + sulfur. Disease was assessed weekly between 90 and 140 days after plating (dap) using the FL 1-10 scale, a visual estimation of defoliation and disease severity, and as the number of leaflets with leaf spot (leaflet incidence) and the mean number of lesions per leaflet (leaflet severity) for 10 lateral branches per plot. As expected, defoliation assessments were significantly lower for the sulfur mixture treatments than the DMI and QoI treatments alone in most cases (P0.05). This suggests that the mechanism of reduced defoliation is due to fewer leaf spot infections rather than increased plant tolerance.1.CHAPTER 1 LITERATURE REVIEW 6 2.CHAPTER 2 FIELD RESEARCH ON SULFUR SYNTHETIC FUNGICIDE MIXTURE EFFECTS ON LEAF SPOT DISEASE SUPPRESSION a.INTRODUCTION 14 b.METHODS 17 i Field Experiments Experimental design and treatment structure ii iii Disease Assessment iv Statistical Analysis c RESULTS 21 d DISCUSSION 31 3 CHAPTER 3 FIELD RESEARCH ON SULFUR SYNTHETIC FUNGICIDE MIXTURE EFFECTS ON PEANUT RUST SUPPRESSION a INTRODUCTION 33 b METHODS 35 i Field Experiments ii Experimental design and treatment structure iii Disease Assessment iv Statistical Analysis c RESULTS 38 d DICUSSION 40 4 CHAPTER 4 LAB RESEARCH ON SULFUR SYNTHETIC FUNGICIDE SULFUR MIXTURE EFFFECTS ON Nothopassalora personata GROWN ON PDA MEDIA a INTRODUCTION 42 b METHODS 44 i N personata Isolates and N personata Monocultures Treatment Production ii iii Lawn Production iv Conidia Acquisition v Evaluation c RESULTS 47 d DISCUSSION 51 5 REFERENCES 53Culbreath, AlbertCantonwine, EmilyTurco, JenniferM.S.Biolog
The Tangelo Park Program: A Historical Case Study of the Program’s First 25 Years Through the Lens of Social Capital
Full text linkBeginning in the mid-1990s, Florida hotelier Mr. Harris Rosen focused his philanthropic efforts on the creation of the Tangelo Park Program, an initiative that intentionally coupled free preschool with a full-ride scholarship for a public college, university, or vocational school in the state. The Tangelo Park Program has become a national model of how private citizens can positively impact their communities by addressing the root causes of poverty, despair, and social disintegration.
This study utilized archival records and one-on-one stakeholder interviews with divergent voices to explore four research questions: how the program built social capital, how the assets-based approach developed self-interest and collective interest, how the program contributed to student- and neighborhood-level outcomes, and what are the best practices that emerged from the program’s first 25 years. The findings can inform other communities in the customization and implementation of their whole-child programs.
The findings reveal that efforts to cultivate social capital must begin with the buy-in of the community’s residents, institutions, and formal and informal leaders. Grassroots social capital-building requires trustworthiness and follow through, purposeful listening, a neighborhood presence, and respect for the will of the community. Recognizing cultural norms and mores is fundamental to successful interactions. Engaging families as partners in their children’s education is paramount, and encourages the prosocial behaviors of cooperation and shared decision-making. This program was the impetus for children in Tangelo Park internalizing their potential for success, thus resulting in high school and college graduation rates that far outpace the state and nation. The program’s 1 return on investment as measured by degree completion and a reduction in crime is indicative of the transformation that defines this urban neighborhood.Chapter I: INTRODUCTION 1 -- Tangelo Park Program Background 1 -- Purpose of the Study 4 -- Research Questions 4 -- Rationale for Mixed Methods 5 -- Outline of Dissertation 6 -- Chapter II: LITERATURE REVIEW 7 -- Theoretical Framework: Social Capital 7 -- Human Capital 13 -- Collective Efficacy 14 -- Applications of Social Capital 17 -- Educational Success Via Social Capital Development 20 -- Neighborhood-Level Factors 24 -- Socioeconomic-Based Factors 25 -- School-Based Factors 26 -- Individual-Level Factors 27 -- Tangelo Park Program Beginnings 28 -- Preschool to Post-Secondary Education 30 -- Evidence of a Successful Strategy 32 -- Shifting Neighborhood Demographics 37 -- Program Sustainability 40 -- Broadening Program Impact 42 -- Chapter III: METHODOLOGY 45 -- Overview 45 -- Sample Selection 46 -- Data Collection 48 -- Data Analysis 52 -- Ethical Considerations 53 -- Chapter IV: RESULTS 55 -- Overview 55 -- Historical Context of Tangelo Park 56 -- Addressing Social Ills in an Urban Neighborhood 56 -- Harris Rosen and the Origin of the Tangelo Park Program 58 -- Defining a Vision and Charting the Course 58 -- Implementation and Enhancement of the Program 60 -- Paving the Way with In-Home Preschools 60 -- Bridging the Gap From Preschool to College 61 -- Developing Informed and Involved Parents 62 -- Community Policing in Both Name and Practice 64 -- A Framework for Notable Leadership 65 -- Building and Sustaining Social Capital 65 -- Collaboration as an Impetus for Trust-Building 65 -- Forging Credibility, Reliability, and Intimacy 66 -- Fostering Purposeful Relationships 67 -- Social Capital Igniting Academic Success 70 -- Sustaining Social Capital Throughout the Decades 73 -- Evidence of Neighborhood Transformation 76 -- Bolstering an Intergenerational Sense of Community 76 -- Enhancing the Physical Environment 77 -- High School Graduation as the Expectation 78 -- A Collateral Benefit: Reduction in Crime 79 -- Sustainability and Replication 80 -- Misalignment of Mission and Scope 82 -- A Model Worthy of Replications: The Sum of Its Parts 84 -- Race as a Blockade to Replication 86 -- Not All Philanthropists Are Created Equal 87 -- Social Capital-Building as the Precursor to Replication 87 -- Strategies for Eliminating Barriers to Replication 89 -- Impacts of COVID-19 90 -- Impacts of Black Lives Matter 92 -- Chapter V: CONCLUSION 95 -- Project Summary 95 -- Findings and Implications 96 -- Approach to Data Collection 96 -- Research Questions 97 -- Limitations and Key Assumptions 103 -- Directions for Future Research 105 -- REFERENCES 108.Davis, BrittDziuban, CharlesLaPlant, JamesD.P.A.Public Administratio
Experiences that Motivated Academic Librarians to Choose Management: A Narrative Inquiry Approach
No full textMany Library and Information Science program students state that they are not interested in management positions. Many would prefer to focus on a subject specialty or technical services. When students are interested in management, there is no clear course of study. To understand what motivated some librarians to choose to become managers, and what motivates them to keep being managers, I used a narrative inquiry approach to collect the experiences and stories of librarians who are currently managers at academic libraries in the southeastern United States. The research question I used as a framework for my study was: What experiences motivate academic librarians to become managers?Six librarians participated in my study. The participants were purposefully selected because they were current managers below the rank of dean at an academic library in the southeastern United States. The data were collected using a semi-structured interview process designed to gather experiences that could be shaped into a narrative that conveyed each participant's stories in a meaningful way to the teller and the reader.
The analysis of the data resulted in four themes: (1) parental influence, (2) management/leadership, (3) management education, professional development, and (4) managerial motivation. These findings have implications for current and future managers, those tasked with educating managers, and those who need to hire and support managers at academic libraries.Workman, JamieAlemanne, NicoleMost, LindaEd.D.Curriculum, Leadership & Technolog
The CROWN Act of 2019 and the Possible Implementation of it in Title VII of the Civil Rights Act of 1964
No full textThe original Title VII of the Civil Rights Act of 1964 was meant to resolve many issues in the U.S. as it pertained to racial discrimination. The present study seeks to determine ways Title VII of the Civil Rights Act of 1964 may be expanded. One proposal is to expand the protection of African Americans from being discriminated against based on their innate hair texture or desired hairstyle. Dove, as a part of Unilever, developed a petition to initiate the discussion of race-based discrimination, which targets individuals whose desired hairstyle is its natural state or a cultural staple.Wilfred, ShaniLovett, MarilynMcClure, StephanieD.P.A.Political Scienc
Examining Church Volunteer Retention and Service Time through a Self-Determination Lens
Full text linkThis study examined the retention of volunteers in religious organizations and focused on the variables within these religious organizations to determine why volunteers stay or leave. The study sought to determine whether one or more of the sub scales of self-determination theory may serve as an independent variable in volunteer retention. The study was structured to identify a possible relationship between the sub scales of self-determination theory and the length of time that a volunteer serves in the church. Data from three personal demographic categories indicate motivational averages tended to increase with age and with educational attainment increased; and males tended to have slightly higher motivational averages than females. Data in all six volunteer demographic categories indicated higher motivational averages the more a volunteer connected, served, and engaged a church. A Spearman rho’s analysis identified perceived competence and interest/enjoyment both were shown to be statistically significant and can both reject the null hypothesis. A Cohen’s d test found that six motivation sub scales indicated having a large effect size for the volunteers who have served for a year or more. In conclusion of this study, there is direct indication that one or more of the sub scales of self-determination theory may serve as an independent variable in volunteer retention. Further, there is clear indication that the length of time a volunteer serves in a church does matter. The motivational impact on volunteer retention is greater once a volunteer has served for one year or longer. Thus, if churches can instill perceived competence and interest and enjoyment within their volunteers for at least one year, the likelihood of retaining that volunteer increases the longer the volunteer serves.Lanning, RebeccaBuning, MeganJames, ChristineD.P.A.Public Administratio

Exploring How Speech-Language Pathologists Recall Changing Demographics and Assessment Practices Related to Multicultural and Multilingual Children: A Retrospective Study
Full text linkIn 2023, immigrants and their United States born offspring accounted for approximately 90.8 million individuals (27%) of the civilian noninstitutionalized U.S. population (Batalova, 2024). Compared to 2010, this is a rise of about 14.7 million (20%). As the global population becomes more diverse, speech-language pathologists (SLPs) face the challenge of working with families representing various cultural and linguistic origins. The accurate diagnosis of speech and language impairments in multilingual children presents a significant clinical challenge for SLPs in the United States, where linguistic variety and communication difficulties are common (Kohnert & Medina, 2009). SLPs must refrain from using universal assessment methods, as members of cultural groups have cultural and individual identities. Appropriately assessing multilingual and multicultural children is a top priority for SLPs, and this study highlights the change in caseload demographics and the extent to which clinicians practice incorporating identified best practice methods into their evaluation methods over time. Data were gathered through an online survey of school-based SLPs in the United States. The responses of 457 individuals were included. The data were analyzed using frequency distribution. Chi-square analysis and a paired sample t-test were used to compare responses. Results indicate that most SLPs and student teams continue to use English-only measures during multilingual assessments. In addition, years of experience were not significant in the use of English-only standardized assessments. Reports suggest that SLPs and student teams continue to use English-only standardized assessments often. Collaboration was the only identified assessment practice that demonstrated an increase in experience. The investigation identified the need for clinicians to enhance their practice by adopting and improving their evaluation methods through continuous implementation of best practices when assessing students from diverse backgrounds.Lamb, KatherineCarter, MatthewGorham-Rowan, MaryS.L.P.D.Communication Sciences and Disorder
