When they see us: racial criminalization, racial stigma, and identity in a Midwest college town
Authors:   , Grayer Julien
Published: September 2022

Racial stigma and racial criminalization have been centralizing pillars of the construction of Blackness in the United States. Taking such systemic injustice and racism as a given, then question then becomes how these macro-level injustices are reflected in micro-level processes. This project uses critical interactionism and stigma theory to explore the potential implications for racialized identity construction and the development of 'criminalized subjectivity' among Black undergraduate students at a predominately white institution of higher education in the Midwest. This study utilizes semi-structured interviews to not just gauge the implications of racial stigma and criminalization on micro-level identity construction but also how understandings of these issues can change across space and over the course of one's life. This was rooted in a continual process of awakenings, reflection, and interactions with participants gaining more complex appreciation of their racial identities as they grew older. Students also were increasingly aware of racial stigma and criminalization as a social fact but did not internalize it as a true reflection of who they were as people. Sensitivity to membership in a criminally stigmatized racial group was also shaped by perception and anticipation of navigating spaces. University life also became a site of these processes; college-aged peer groups served as important sites of collective identity-building and students juxtaposed space and region in ways that reinforced subjective sensitivity to being in a racially stigmatized group. This research contributes to scholarship that applies a critical lens to Goffmanian stigma rooted in Black sociology and from the perspectives of the stigmatized themselves.
Production network, aggregate idiosyncratic accounting earnings, and aggregate output
Authors:   , Guo Zhujin
Published: September 2022

This study examines whether the input-output production network affects earnings predictability for aggregate output. Decomposing aggregate idiosyncratic earnings growth according to the production network characteristics, I find that aggregate idiosyncratic earnings growth of closely connected firms and central firms predict future (one and two quarter-ahead) GDP. I also show that the predictive power is not fully anticipated by professional macro forecasters. Overall, this paper sheds light on the network-based propagation of microeconomic shocks and the origin of macroeconomic fluctuations.
Text selection and students' motivation to read
Authors:   , Hoddinott Margaret
Published: September 2022

This study explores the relationship between features of the books students selectfor independent reading and their motivation to read. After spending 15 to 20 minutes reading self-selected texts, participants (n = 340) completed the Motivation to Read Profile-Revised (MRP-R) (Malloy et al., 2013) and provided information about their book. A significant positive correlation (p < .001, d = .361) was found between the enjoyment students experience from the book and their motivation to read. Students who loved their book had significantly higher median motivation scores compared with their peers who did not love their book. Associations between motivation and other features of the book (i.e., format, genre, thickness, visual features) were either very weak or not statistically significant. Follow-up semi-structured interviews (n = 8) revealed that highly motivated and unmotivated students alike know their reading preferences but that unmotivated students are afforded less freedom in their text selections. This study adds further support for the importance of matching children with compelling texts.
Diagnostic competencies of those administering and interpreting cognitive (IQ) assessments for special education placement within Missouri: perceptions of special education directors and process coordinators
Authors:   , Holloway Jewel L.
Published: September 2022

This study explored the policies and laws established to govern the process school districts within Missouri use to administer and interpret cognitive assessments, as well as the perceptions of special education administrators and process coordinators. Archival data from DESE as well as from the Missouri Association of School Psychologists were examined to provide supporting information. This analysis was mixed methods in nature while employing a pragmatic approach. The researcher sought to understand the experiences of special education administrators and process coordinators as described by the participants. Both the qualitative and quantitative portions of the findings provided rich and dynamic insight into the participants' perceptions regarding the current assessment practices of Missouri K-12 districts. They also provided cognizance of the qualifications of personnel utilized to administer and interpret cognitive assessments in Missouri K-12 districts as well as how those qualifications compared to established law, policies, and standards. These paralleled need for educational leadership at the state level to provide clarity and communication to Missouri school districts as well as consider measures of accountability, funding, and recruitment.
Strategies for fostering self-determination in students with autism spectrum disorder: a qualitative study of community college faculty and staff
Authors:   , Hudgens T. Michelle
Published: September 2022

Students with autism spectrum disorder (ASD) are enrolling in college more frequently, yet their graduation rates remain low. One reason posited is lack of self-determination (SD) skills, which help students act on goals. This study investigated how faculty at a community college support students with ASD in developing SD skills. The study used Garrison-Wade and Lehmann's (2009) framework for students' with disabilities transition to community college to evaluate data regarding how faculty accomplish this goal and how they communicate with DS staff. The study used basic qualitative methods, specifically semi-structured interviews with 23 faculty, five DS staff, and two education site directors. Findings include that faculty use a variety of strategies to communicate with students, yet faculty feel tension between helping students regulate behaviors and allowing autonomy. All three groups of participants indicate that rapport with and trust for each other are important, but when these qualities are absent, some faculty find help through informal supports. All groups of participants indicate that while accommodation letters are a good starting place to support students with ASD, they provide little help on how to reinforce SD skills. Ultimately, accommodations are supplemented by faculty opting to work with students beyond the letter.
Information management and security protection for internet of vehicles
Authors:   , Kang Jian
Published: September 2022

Considering the huge number of vehicles on the roads, the Internet of Vehicles is envisioned to foster a variety of new applications ranging from road safety enhancement to mobile entertainment. These new applications all face critical challenges which are how to handle a large volume of data streams of various kinds and how the secure architecture enhances the security of the Internet of Vehicles systems. This dissertation proposes a comprehensive message routing solution to provide the fundamental support of information management for the Internet of Vehicles. The proposed approach delivers messages via a self-organized moving-zone-based architecture formed using pure vehicle-to-vehicle communication and integrates moving object modeling and indexing techniques to vehicle management. It can significantly reduce the communication overhead while providing higher delivery rates. To ensure the identity and location privacy of the vehicles on the Internet of Vehicles environment, a highly efficient randomized authentication protocol, RAU+ is proposed to leverage homomorphic encryption and enable individual vehicles to easily generate a new randomized identity for each newly established communication while each authentication server would not know their real identities. In this way, not any single party can track the user. To minimize the infrastructure reliance, this dissertation further proposes a secure and lightweight identity management mechanism in which vehicles only need to contact a central authority once to obtain a global identity. Vehicles take turns serving as the captain authentication unit in self-organized groups. The local identities are computed from the vehicle's global identity and do not reveal true identities. Extensive experiments are conducted under a variety of Internet of Vehicles environments. The experimental results demonstrate the practicality, effectiveness, and efficiency of the proposed protocols.
Protecting the environment: the effects of green menu design on restaurant customers' willingness to pay
Authors:   , Lee Soojin
Published: September 2022

The present study conducted experiments to reveal the relationship between various message appeals and customers' menu selection processes. There is a dearth of studies that explore the consumer green menu selection behaviors, particularly in full-service restaurants in the United States. By utilizing the Value- Belief-Norm (VBN) theory and integrating the Elaboration Likelihood Model (ELM) into the Dual Coding Theory (DCT), the present study is intended to investigate the effects of green menu designs that may influence willingness to pay more at full-service restaurants. A total of 521 samples were collected through MTurk. Various statistical analyses revealed meaningful results that can be utilized by restaurant marketers with insights for developing effective green marketing strategies to attract and retain customers.
Computational studies of gases adsorbed on graphene-like materials
Authors:   , Lombardi Todd
Published: September 2022

Nanoporous activated carbons generate interest for their gas storage and separation potential. Generally, adsorbents are assumed rigid, even though they are formed by feeble quasi-2D flakes of graphene. In 2019, Schaeperkoetter et al.^1 observed swelling of graphene oxide frameworks (GOFs) upon supercritical adsorption of various gases. We performed molecular dynamics (MD) simulations of methane and xenon in various models of GOF's with interaction parameters derived from ab initio Density Functional Theory. We observe a monotonic increase of the interlayer spacing consistent with experiments only for a model of benzene-1,4-diboronic acid (DBA) molecules bonded covalently to graphene on both sides of the pore at random orientations, establishing the structure of the DBA-GOFs. Adsorbents are also useful for the separation of gases, e.g., methane and carbon dioxide from organic waste biogas. We performed MD and grand canonical Monte Carlo simulations of the coadsorption of CH4 and CO2 in pores of different sizes and surface functionalization. We observe significant selectivity for the adsorption of CO2 - potentiated by the presence of polar surface groups and determined optimal conditions for gas separation in this system. Finally, atomically flat graphene allows the emergence of two-dimensional films of weakly adsorbed helium with interesting quantum properties. We performed ab initio 2nd order Moller-Plesset calculations with large basis sets of the interaction of 1, 2, and 3 He atoms on graphene-like systems. The interaction parameters are then used in the Bose-Hubbard model, and under certain conditions it is predicted that superfluid or Mott insulating phases can occur.
An implementation fidelity evaluation of the McKinney-Vento homeless assistance act in the state of Missouri
Authors:   , Masterson Thomas O.
Published: September 2022

Homelessness continues to be a growing reality for students within the K-12 public school system. The McKinney-Vento Homeless Assistance Act (MVA) was in response to this growing reality, focused on ensuring students and families were better supported by public schools when they experienced homelessness. While research does exist on why MVA is needed, the impact it can have, how districts have failed to appropriately comply, and how states have created additional legislation, there is a gap in research pertaining to the implementation of MVA within the state of Missouri. Additionally, there is no state-specific legislation in addition to MVA. As a result, the researcher desired to explore if MVA was being implemented, as designed, within the state of Missouri. Furthermore, the researcher desired to equip district administrators with a better understanding of implementation and tools to increase their implementation of MVA, better supporting students and their families experiencing homelessness. The findings connected to both research questions explored recognize that compliance may not be the primary concern, but that there are opportunities to better meet the needs of students identified as homeless. As a result, strategies have been recommended to ensure districts are more focused on the needs of their homeless population. There are abundant opportunities to continue this important research, but this research serves as a foundation for exploring homelessness within Missouri. Specifically, there is an opportunity to research if the perceptions and realities align with the perceptions of homeless liaisons. As well, there is an opportunity to conduct research that involves a larger population of homeless liaisons, plus their supervisors. There is also an opportunity to research and evaluate how the state is implementing, supervising, and evaluating the McKinney-Vento Homeless Assistance Act within Missouri.
The graduate student novel: a new subgenre in university fiction
Authors:   , Walz Kacy
Published: September 2022

This study examines novels with graduate student protagonists, referred to as graduate student novels or grad novels, and argues that such novels should be considered distinct from others about university experiences. It builds on previous scholarship that distinguishes between novels about professors and about undergraduates as academic and campus novels, respectively. Through the consideration of several grad novels, three common elements are identified as characteristic of the subgenre: a grad student protagonist who is introduced at a moment of stasis in their research or academic progress; the intervention of fate which dramatically impacts the protagonist's story, and a conclusion that alludes to or explicitly depicts a kind of success in academia. The recognizable characteristics that illustrate the major differences, also provide helpful avenues toward examinations of the image of graduate scholarship produced by grad novels and different issues related to higher education. The initial stasis is examined as allegorical for the recently identified developmental stage of the quarter life and the quarter life crisis. The significance of fate and the protagonists' lack of agency is discussed alongside considerations of anti-intellectual sentiments. And the fictional academic success is read in comparison with academic quit lit written by scholars leaving academia. This dissertation considers the graduate novel as capable of being read both as an allegory and as representative of the actual experiences of scholars-in-training. It concludes with a contemplation of the potential alternative interpretations of readers inside and outside of academia.
Hospital acquired pressure injury in adult orthopedic spine surgery patients: risk factors and risk assessment tools
Authors:   , Becker Colleen M.
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Approximately 25 percent of all hospital acquired pressure injuries (HAPI) begin in the perioperative area. The study purposes were to identify risk factors in adult surgical patients undergoing orthopedic spine surgery in the prone position and compare three HAPI risk assessment tools in perioperative patients. This was a single center, retrospective study electronic medical record (EMR) data. HAPI incidence was 1.14 percent (51/4466). Person, nursing, and environmental factors were analyzed using logistic regression. Factors from each domain predicted HAPI development. HAPI was associated with longer length of stay and discharge to home with support or a sub-acute facility (p [less than].001). Using Receiver-operating characteristic (ROC) analysis, area under the curve (AOC) of the ROC for the Braden Risk Assessment Scale (BRAS) was not different from 0.5 (p [less than].200). AUC of the ROC for Scott Triggers Tool and Munro PACU Total score were different from 0.5 (p [less than].001). preoperative BRAS cutoff value of 18 yielded Sensitivity 36 percent and Specificity 75 percent. Munro PACU Total cutoff value of 29 yielded Sensitivity 87 percent and Specificity 42 percent. Scott Triggers cutoff value of 1 yielded Sensitivity 76 percent and Specificity 44 percent. A Munro Preoperative score may be more useful than a preoperative BRAS score to guide nurses in planning and implementing preoperative HAPI interventions. Given the low Specificity, the Munro Risk Assessment Tool requires refinement to improve the psychometrics. Prospective research is needed to test perioperative interventions to decrease HAPI in this specialty population and refine the Munro Tool.
A duty to care: male perspectives on their role as caregivers for persons with Alzheimer's Disease or related dementia
Authors:   , Bueno Michael V.
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] People with Alzheimer's Disease or related dementia (ADRD) require a significant amount of care due to its progressive and chronic nature. Most of the care provided to people with ADRD come from family caregivers (FCGs). The importance of the FCG is significantly increasing as it is estimated that the number of people with ADRD in the U.S. will double by the year 2050. Although caregiving provides many personal, familial, and economic benefits, the progressive and heavy demands of providing care for someone with ADRD places caregivers at risk for negative health outcomes. Most caregiving research has focused on females. Although female caregivers have reported more negative outcomes, men still report significant levels of burden. With the aging population and increased need for caregivers, there is a gap in knowledge exploring the male caregiving experience. Understanding male caregiving experiences can inform clinicians on developing future strategies to tailor support for this underrepresented group. The purpose of this qualitative descriptive study was to explore the experiences of male FCGs of people with ADRD. The Caregiver Identity Theory (CIT) was used to guide the study exploring participants' perception of self-identity within their caregiving relationship and self-identity as a male. Eleven male caregivers, recruited through social media and community resources, were interviewed by telephone or Zoom. Interviews were recorded, transcribed, and analyzed using thematic analysis. Four major themes emerged highlighting males' struggles with the unfamiliar caregiving role and changing identity, their acknowledgement of personal growth and discovery through caregiving, challenges in finding the "right" kind of support, and perceived reshaping of masculinity through the caregiving role. Within each major theme, sub-themes were identified to further exemplify the male caregiving experience. Male caregivers express unique experiences as FCGs suggesting future research is needed to explain gender differences in caregiving and identify additional factors that influence male caregivers' experiences. Furthermore, findings indicate clinicians should tailor support strategies for male FCGs' as they fulfill this potentially unfamiliar role.
"Globalizacion: una aproximacion ecofeminista a la novela mexicana contemporanea escrita por mujeres"
Authors:   , Keyser Celia Alpuche
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] La presente disertacion examina la representacion del impacto de la globalizacion y sus efectos daninos en el medio ambiente y la mujer en tres textos literarios escritos por escritoras mexicanas contemporaneas. La mujer que buceo dentro del corazon del mundo (2010) escrita por Sabina Berman, Las mujeres de la tormenta (2012) de la autoria de Celia del Palacio and Solo por ser mujer (2015) obra por Marisol Ceh Moo presentan protagonistas de diversas clases sociales y origenes que elaboran contradiscursos que denuncian problematicas como la discriminacion y el racismo; de modo que, elaboran mecanismos de resistencia para enfrentarse al sistema hegemonico dominante que se refuerza con el avance del capitalismo y la globalizacion. El interes de la investigacion se centra en como las mujeres y la naturaleza estan bajo el mismo patron de subyugacion, de modo que cada protagonista de las narrativas seleccionadas siente la obligacion de mitigar la injusticia y la degradacion ambiental a su alrededor. A partir de la perspectiva ecofeminista se discute como estas escritoras destacan la importancia de que las mujeres asumen la responsabilidad de cambiar positivamente el curso de las politicas ambientales; al mismo tiempo que se deconstruyen las categorias fijas de identidad tradicionalmente asumidas por el genero biologico. Por ultimo, es importante senalar que no obstante que son muchas las ventajas de la globalizacion; es urgente evidenciar la gravedad del impacto negativo de este proceso en la sociedad, sobre todo en la mujer y en la naturaleza.
Multilevel structural equation modeling for 2-1-1 mediation using Bayesian method
Authors:   , Kim Minsun
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] The multilevel mediation effect from the 2-1-1 designed model was analyzed using the Bayesian method. For Bayesian analysis, eight default priors and one informative prior were used. The priors for the location and the variance parameters associated with the mediation effect were diversely specified and compared in terms of how the estimated mediation effect changed depending on the prior distribution. Findings are analyzed in terms of convergence, relative bias, RMSE, coverage rates, and power for all location and variance parameters. Furthermore, based on different prior distributions, the data conditions that best estimated the multilevel mediation effect were identified. Followed by the simulation findings, a sensitivity analysis was conducted using this empirical example to determine the robustness of the results through various analyses. The prior sensitivity analysis reveals that the estimate of the indirect parameter was robust when the EB priors that contained even a small amount of data information or the informative prior were selected. The findings from this study have implications for specification of EB priors, selection of preferred methods, and appropriate data conditions when using multilevel mediation model. Further investigation of extended models, diverse data conditions, and different types of prior conditions is warranted.
Improving cardiac care delivery using predictive and prescriptive analytics
Authors:   , Salah Haya
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Endured by the growing prevalence of cardiovascular diseases (CVDs), the demand for cardiac care services has increased. On the other hand, the supply of cardiologists is expected to be insufficient to meet this growing demand. Considering this imbalance between demand and capacity, cardiology clinics strive to improve their services. Thus, this dissertation proposes two approaches for improving cardiac care services through the application of predictive and prescriptive analytics. The first approach develops an efficient appointment system (AS) that allocates patients' demand during the clinic session effectively to improve resource utilization and patient satisfaction. The proposed AS also addresses the problem of clinical uncertainties, such as patient no-shows and service-time variability, which adversely impact AS efficiency by developing a predict-then-schedule framework. In the predict step, patient-specific no-show risk and service duration are estimated using machine learning (ML) models. The schedule step determines the appointment time and interval for each patient using a sequential AS that leverages the ML predictions. In addition, four new ML-enabled sequencing rules are proposed. The proposed approach and sequencing rules are validated using real clinical data. Besides, the effectiveness of integrating ML-based uncertainty predictions into the AS design is also evaluated for 32 different clinic environments. Results indicate that an AS design adopting the predict-then-schedule approach always dominates the conventional system and could improve the efficiency by 60 percent. The new sequencing rules can improve the AS performance by up to 40 percent when compared to the existing policies. Finally, several managerial insights on sequencing and overbooking are also provided. On the other hand, the second approach develops an ML-based model to predict the long-term CVD risk that can aid in the early detection of CVD. Unlike the existing tools for CVD risk assessment which are only applicable to adults and use cross-sectional data. This research provides the first long-term ML-based CVD risk prediction model among adolescents based on a longitudinal dataset. Our results indicated the capability of ML models to accurately predict the long-term risk of CVD among adolescents. In addition, the most significant factors for predicting CVD risk among adolescents are identified. Furthermore, the proposed model can be used to identify individuals who are at high risk of developing CVD early in life and provide them with the necessary guidance and preventive treatment, which improves the quality of life, lower healthcare costs, and reduces the demand for cardiac care services later.
Active deformation of the South Granite Mountain Fault System: reactivated compressional faults vs. extentional overprinting
Authors:   , Potter Michael R.
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Quaternary faulting in and around Wyoming's Wind River Basin may pose a moderate earthquake risk for dams and other infrastructure within the region. The South Granite Mountains Fault Zone, located adjacent to the Wind River Basin, is one of several Quaternary faults in the region. The South Granite Mountains formed during the Late Cretaceous Laramide orogeny (75-45 Ma). Subsequently, during the Eocene, the extensive downfaulting and downfolding caused the Precambrian Mountain core to collapse forming the Sweetwater Graben. Recent Quaternary deformation is expressed as fault scarps along the north side of the Granite Mountains (2-4 meters). These features were originally studied in the 1980s but have received little attention since. In particular, the nature and style of faulting of this recent deformation was previously undocumented, and prior age estimates were broad. This study applies new methodologies to assess the active tectonics and earthquake potential of the South Granite Mountains Fault System. Low-altitude aerial surveying using drones facilitate the measurement and analysis of fault scarp morphology. From this scarp degradation modeling is applied to faulted surfaces with an age range of [greater than] 201 to 16 ka. Results indicate long term dip slip rates between 0.01-0.05 mm/yr, and Horizontal extension rates between 0.01 - 0.03 mm/yr along the Ferris Mountains front. Shallow seismic reflection profiling is used to image the fault geometry indicating normal faulting at high angles (83 degrees). Offset of the unconformity between the Split Rock Formation and the Quaternary sediments is estimated at 10-13 meters. Using modern rates of faulting suggest quaternary faults initiated at 80-104 ka.
Experimental static resistance of cold-formed steel roof truss systems
Authors:   , Treece David Michael
Published: September 2022

[EMBARGOED UNTIL 6/1/2024] Critical infrastructure vulnerable to attack or located in areas of high threat requires increased protection. U.S. facilities at home and abroad have seen disruption and destruction due to lack of capability to fully resist attack. Increasing effort to improve the building structure, particularly building envelope systems, can improve the life-safety and continued operability of critical infrastructure under adverse circumstances. The popularity of cold-formed steel (CFS) building components has seen a sharp rise in recent years due to its low cost, high strength, ease of construction, and design flexibility. Despite its extensive use, no design criteria exist for the design of cold-formed steel roof systems under blast load. While extensive studies have been conducted on blast load on CFS walls, sufficient research has not been done to develop adequate design procedures for CFS roof systems. Past research has explored the behavior of these truss systems up to ultimate capacity, but the full inelastic behavior was not fully captured. Since many structures are allowed to sustain permanent deformations in blast scenario, it is critical to the safety of building occupants to fully understand the non-linear response of building envelope systems. Dynamic testing and numerical analysis are uneconomical and tedious for every design variation, so the simplified single degree of freedom (SDOF) approach to dynamic analysis is commonly used to project blast resistance of complicated structural systems. In order to perform the SDOF analysis, a static resistance function is required. This study aims to analyze the full static resistance of full-scale cold-formed steel trusses commonly used in the industry and identify associated failure modes in order to more accurately predict dynamic response with simplified methods. Sixteen unique truss designs were tested under quasi-static loading up to ultimate failure using a mechanical testing system. Three select designs will be discussed in this thesis. A simplified finite element analysis was performed using SAP2000 non-linear analysis and compared to experimental results. Experimental results show that truss performance and absorbed energy are significantly affected by the truss configuration and thickness of truss elements. Results of this study will be used to validate advanced numerical models. The quantifiable application of system capacities will improve future designs of building systems and lead to a more safe and resilient infrastructure.
Black and Afro-Latinx women in public relations: a collaborative autoethnography on the construction of intersectional identities in the workplace
Authors:   , Williams Arzelia
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Public relations is considered a feminized industry with women making up nearly 70 percent of its workforce. However, women only fill 30 percent of the top leadership roles (Angela Chitkara, 2018) and sufficient representation from Black women is lacking among the ranks. To better understand how race, gender, and class intersect in Black and Afro-Latina women PR practitioners' workplace experiences, this study used intersectionality theory as a lens of analysis. Using a collaborative autoethnographic approach, weekly reflections and in-depth interviews were conducted with six Black women working in the public relations profession. Participants noted how their race, gender and class status have shaped how they display their identities in the workplace, campaigns they are assigned to, and opportunities for career advancement in the future. The findings resulted in three major themes: structural and social inequalities, hypervisibility and invisibility, and representation. Findings revealed Black and Afro-Latinx women were being assigned to projects that aligned with their race, gender, or ethnicity and were being unequally paid for their workload. The findings also indicated that many of the participants lacked access to formal networking and mentoring opportunities or were considered for promotions despite their performance. Lastly, the findings revealed an overall lack of representation has shaped their perception of upward mobility and leadership. However, the participants expressed that where there is a gap in representation, they can strive to fill it. Ultimately, this study has fulfilled the need for more research regarding the understudied topic of non-White or Caucasian races and ethnicities outside the realm of gender relations (Vardeman-Winter et al, 2013).

Water Use for Seepage-Irrigated Watermelon with Plastic Mulch in Florida
Authors: Shukla Sanjay , Shrestha Niroj K.
Published: September 2022

In Florida, watermelon is an important crop that accounts for a significant part of the state’s agricultural water use. Depending on the type of production system and climate, the water use of this crop can vary. In Florida, watermelon is predominantly grown on raised plastic-mulched beds. To develop improved water management and allocation plans, accurate water use estimates for watermelon are needed. Seepage irrigation under plastic mulch is a common production system used to produce watermelon in south and northeast Florida where the water table is shallow. Plastic mulch alters the rainfall entry and soil temperature of the raised beds and can significantly affect evapotranspiration. As there is no information on seepage-irrigated watermelon grown on plastic mulch for subtropical Florida, this 4-page fact sheet summarizes the results from a crop water use study for the seepage-irrigated watermelon in south Florida.

Waterhyacinth is one of the world’s worst aquatic weeds and is Florida’s most intensively managed floating plant. Dense mats formed by this species interfere with human uses of water bodies and disrupt ecosystems by preventing penetration of light and oxygen into the water column. This attractive, free-floating aquatic plant grows throughout the year in southern Florida but often dies back during the winter in the northern parts of the state. Waterhyacinth is cultivated as a water garden and pond plant, but cultivation, sale, and possession of this noxious weed is prohibited in Florida. This 5-page fact sheet was written by Lyn A.

Paraná Pine, Araucaria angustifolia: An Ancient-Looking Conifer for Modern Landscapes
Authors: Knox Gary W.
Published: September 2022

Paraná pine is a primitive-looking conifer valued for its unusual horizontal branching, interesting triangular-shaped needles, and neat, symmetrical form. The primitive appearance of this evergreen tree results from its resemblance to and relationship with an ancient group of Araucaria-related conifers that dominated forests more than 145 million years ago. This tree once covered vast areas in southern Brazil, Argentina and Paraguay. Native Americans harvest the seeds for food. It was an important timber tree for European settlers, and it was logged extensively through the 20th century. Now one of the rarest trees in Brazil, Paraná pine is considered critically endangered due to habitat loss and exploitation. This evergreen conifer grows too large for most residential situations, but is best used as an accent or conversation piece in large-scale landscapes. This 3-page fact sheet was written by Gary W. Knox and published by the UF Department of Environmental Horticulture, November 2014.

Candidate Species for Marine Ornamental Aquaculture: Porkfish, Anisotremis virginicus
Authors: Cassiano Eric , Barden Kevin
Published: September 2022

The porkfish is a member of the grunt family, which create a characteristic “grunting” sound by rubbing their pharyngeal teeth together during periods of agitation or courtship. Many species of grunts are popular in public aquariums because they’re abundantly available, and their schooling behavior and bright colors create interest in aquarium exhibits. Porkfish also have additional appeal to aquarists because they are “cleaner” fish during their juvenile phase, picking parasites from larger fish and other vertebrates. Scientists and aquarists have recently achieved a greater understanding of appropriate aquaculture protocols for grunts in general and porkfish in particular. These characteristics and advancements have led to porkfish being identified as a candidate species for commercial aquaculture.

Establishment Cost of Avocados in South Florida
Authors: De Oleo Braulia , Evans Edward A. , Crane Jonathan H.
Published: September 2022

A major concern for the future of the Florida avocado industry is laurel wilt disease (LW), which is caused by fungus transmitted by the ambrosia beetle. Cost-effective management of LW relies heavily on the early detection and destruction of affected trees (sanitation). While not an official recommendation, some suggest that since the beetles are less attracted to younger trees, growers might consider leaving the young orchards in production while replanting only older and less productive orchards. Since the long-term survival of the Florida avocado industry may ultimately depend on a combination of eradication, prophylactic treatment, and replanting the trees, the purpose of this article is to provide an updated guidance on the costs of establishing an avocado orchard. Information presented in this study is based on interviews with growers, orchard service companies, extension agents, and other industry personnel. It is intended as a guide only to make production decisions, prepare budgets, and investigate insurance options. A follow-up document to this one will focus on the cost and return of maintaining an orchard after it has been established. This 9-page fact sheet was written by Braulia De Oleo, Edward A. Evans, and Jonathan H. Crane, and published by the UF Department of Food and Resource Economics, October 2014.

Florida Strawberry Producers’ Experiences with Anthracose and Botrytis Fruit Rot, and Producers’ Use of the Strawberry Advisory System
Authors: Borisova Tatiana , Guan Zhengfei , Vorotnikova Ekaterina , Peres Natalia , VanSickle John
Published: September 2022

Florida’s producers use fungicides to manage anthracnose and botrytis fruit rot diseases, which find favorable growth conditions in Florida’s climate and can reduce strawberry yields and profits. The Strawberry Advisory System (SAS) uses information about weather conditions and user-entered information about past fungicide applications to evaluate the potential spread of these diseases in strawberry fields. If the risk of disease spread is low, no fungicide application is recommended, allowing producers to save on fungicide application costs. In this study, we summarize the results of a 2012/2013 survey of strawberry producers, and focus on the questions, How significant is the impact of anthracnose and botrytis on Florida strawberry producers’ yields? What are the typical fungicide application frequencies used by the producers? What percent of strawberry producers use SAS? and Are there any effects of SAS subscription on producers’ fungicide application? This 4-page fact sheet was written by Tatiana Borisova, Zhengfei Guan, Ekaterina Vorotnikova, Natalia Peres, and John VanSickle, and published by the UF Department of Food and Resource Economics, October 2014.

Forest Resource Information on the Internet: Connecting to Today’s Online Resources
Authors: Demers Chris
Published: September 2022

In 1997, the UF/IFAS School of Forest Resources and Conservation (SFRC) published Forest Resource Information on the Internet, which provided detailed information about the Internet: its history, structure, and how to use it. It also provided a sample of forest resource websites. Much has changed since the first publication. This is the third revision of this document, providing updated information on the latest landowner assistance websites available. These state, regional, and national resources can serve as a springboard to a wide variety of natural resource information and programs. This 4-page fact sheet was written by Chris Demers and published by the UF Department of School of Forest Resources and Conservation, May 2014.

Survival of Foodborne Pathogens on Berries
Authors: Palumbo Mary , Harris Linda J. , Danyluk Michelle D.
Published: September 2022

Fresh and frozen berries are popular foods. When berries are picked for fresh consumption, they are usually packed directly without washing because they are highly perishable. There is typically no “kill step” that would eliminate pathogens on fresh or frozen berries. Foodborne illness outbreaks have been associated with the consumption of fresh or frozen berries that were contaminated with pathogenic viruses, parasites, or bacteria. Contamination can occur before or during harvest or during final preparation. This 11-page fact sheet was written by Mary Palumbo, Linda J. Harris, and Michelle D. Danyluk, and published by the UF Department of Food Science and Human Nutrition, November 2013.
Datos sobre los antioxidantes
Authors: Clark Kaitlin G. , Dahl Wendy J.
Published: September 2022

Nuestro cuerpo está constituido de células. Dentro de éstas ocurren constantemente reacciones químicas, que se conocen colectivamente como metabolismo. Estas reacciones son necesarias para la vida, pero algunas veces crean radicales libres. Los radicales libres son moléculas altamente reactivas que pueden iniciar reacciones dañinas en cadena en nuestras células. Esto se conoce como estrés oxidativo. Diversas investigaciones relacionan el estrés oxidativo con muchas enfermedades: artritis, enfermedades de los pulmones (como enfisema), enfermedades del corazón, enfermedad cerebro vascular, ulceras, hipertensión, Parkinson y Altzheimer, distrofia muscular y otras. El estrés oxidativo también contribuye al proceso normal de envejecimiento.
