Multiple herbicide resistance among kochia (Bassia scoparia) populations in southcentral Great Plains

Abstract Multiple herbicide-resistant (MHR) kochia [Bassia scoparia (L.) A. J. Scott] is a concern for farmers in the Great Plains. A total of 82 B. scoparia populations were collected from western Kansas (KS), western Oklahoma (OK), and High Plains of Texas (TX) during fall of 2018 and 2019 (from the various locations), and their herbicide resistance status was evaluated. The main objectives were to (1) determine the distribution and frequency of resistance to atrazine, chlorsulfuron, dicamba, fluroxypyr, and glyphosate; and (2) characterize the resistance levels to glyphosate, dicamba, and/or fluroxypyr in selected B. scoparia populations. Results indicated that 33, 100, 48, 30, and 70% of the tested B. scoparia populations were potentially resistant (≥20% survival frequency) to atrazine, chlorsulfuron, dicamba, fluroxypyr, and glyphosate, respectively. A three-way premixture of dichlorprop/dicamba/2,4-D provided 100% control of all the tested populations. Dose-response studies further revealed that KS-9 and KS-14 B. scoparia populations from KS were 5- to 10-fold resistant to dicamba, 3- to 6-fold resistant to fluroxypyr, and 4- to 5-fold resistant to glyphosate as compared to the susceptible (KS-SUS) population. Similarly, OK-10 and OK-11 populations from OK were 10- to 13-fold resistant to dicamba, 3- to 4-fold resistant to fluroxypyr and glyphosate compared to the OK-SUS population. TX-1 and TX-13 B. scoparia populations from TX were 2- to 4-fold resistant to dicamba and TX-1 was 5-fold resistant to glyphosate compared to the TX-SUS population. These results confirm the first report of dicamba and fluroxypyr-resistant B. scoparia from Oklahoma, and glyphosate and dicamba-resistant B. scoparia from TX. These results imply that adopting effective integrated weed management strategies (chemical and non-chemical) is required to mitigate the further spread of MHR B. scoparia in the region.

Hospitable Historiography and/of the First All-Woman Special Supreme Court in the State of Texas

ABSTRACT Rhetorical scholars working with archival materials face the persistent question: “What happened?” Records are present, yet what they record is absent. This essay addresses the historical narrative of the Texas Supreme Court case, Johnson v. Darr. This event and its expansive archive have been used as evidence for political claims to significance. Drawing from Michelle Ballif, we attempt a “hospitable historiography.” Discussing the tension between the archival “cut outs” and the event’s inherent “eventfulness,” we suggest that archival ruptures may offer insights into the significance of the past. We explore the ethical considerations of historiography, particularly in relation to feminist methodologies and the need to acknowledge the multifaceted identities of historical figures. We conclude, proposing a reevaluation of the event’s significance, challenging traditional interpretive frameworks, and advocating for a more hospitable approach to historiography. The gambit is to know the past otherwise. The potential gain is both methodological and ethical.

Observing the interaction between energy generation carbon emissions and economic conditions could consider generation, intensity, and times of the day.

Management of carbon emissions of regional electricity generation involves resolving much nuanced relationships. However, current studies pertaining to the relationship between energy and the economy utilize only quarterly and annual data and focus on the long-run relationship but are oblivious to temporal associations. This study takes the context of the State of Texas and utilizes per 15min of data between 2007 and 2020 to derive the monthly time series of life-cycle emissions, emissions factor, and energy generation. The study also divides each day into three portions (0:00-8:00, 8:00-16:00, and 16:00-24:00) in order to descend precision down to the hourly level. Impulse-response analysis indicates that (1) employment conditions impact emissions by affecting the amount of electric energy generated, while demographic (population as reflected by property price) tends to impact emissions by affecting the carbon intensity of electricity, and (2) the emissions produced during 0:00-8:00 display different reaction to fluctuation of regional economic conditions compared to emissions produced during other periods, the effect emanates from either energy generation fluctuation or emissions factor shocks. The broader implication of the findings lies in an emphasis on time-interval-specific analysis and concurrent consideration of both energy generation and emissions factors that can lead to optimized policy implementation results.

Using Statewide Transportation Planning Model to Forecast Demand for Electric Vehicle Charging at Stations Along Intercity Highways

The availability of Charging Stations (CSs) with adequate capacity is critical for the growth in ownership and usage of Electric Vehicles (EVs). In the United States, the state Departments of Transportation (DOTs) are responsible for planning CSs along the Interstate, national, and state highways. While the state DOTs have their Statewide Transportation Planning Models (STPMs), most of these models do not represent EVs internally. The state DOTs can only rely on the existing STPMs to forecast the demand for EV charging at specific CS locations in a state’s highway network. This research proposes a methodology that utilizes an existing STPM, EV and non-EV vehicle registration data, and hourly traffic volumes at strategic counting stations to predict the hourly demand for EV charging (charging port occupancy) at proposed CSs. This approach first estimates the volume of all passenger cars that will pass the vicinity of a CS along intercity highways, and identifies the Traffic Analysis Zones (TAZs) of their trip origins. Based on the EV adoption rates of the TAZs, EV range, and EV owner’s charging behavior, the methodology forecasts the volume of EVs that pass the vicinity of a CS and the number of EVs that will stop at the CS to charge every hour of the day. An example problem demonstrated the application of the methodology in the State of Texas. It not only forecasted the hourly occupancy at CSs along three major corridors, but also demonstrated how to determine the capacities of the CSs. The challenges of using the existing STPM and their solutions are discussed. This proposed methodology enables the state DOTs to forecast the demand for EV charging and the capacities at the proposed CSs along intercity highways, thus allowing the DOTs to apply for federal funds to accelerate the deployment of the CSs.

Weathering the pandemic storm: Inter-organizational imitation and hotel survival

No previous studies have provided insights into inter-organizational spillover in hotel market exit behaviors amidst great uncertainty. This study investigates the impact of local pandemic severity on hotel survival rates and identifies inter-organizational imitation moderating this effect. We conduct survival analysis on a sample of 3841 hotel properties in the U.S. state of Texas. Results confirm the detrimental roles of pandemic severity on hotel survival rates. We observe a negative spillover stemming from inter-organizational imitation based on the market exits of same-class hotel peers. Results further unveil that hotels operated by third-party management companies and high-end hotels are less likely to exhibit inter-organizational imitation in their closure responses to the pandemic.

Characterizing Collegiate Recovery Programs in the US and Canada: A Survey of Program Directors.

Collegiate Recovery Programs (CRPs) play a vital and expanding role in supporting students in recovery from substance use disorders and behavioral addictions at higher education institutions. Despite their importance, there is a lack of comprehensive research characterizing CRPs, including their program directors and the nature and influence of their funding streams. A survey was administered to 70 CRP directors across the US and Canada. Directors reported on their CRPs across a variety of site physical features, policy and program offerings, and funding sources, with "sustainable" funding defined as two or more sources. CRP directors were predominantly non-Hispanic, White, and female, with representation from gender and sexual minorities. The highest concentration of directors responding were in the US states of North Carolina, California, and Texas. CRPs with more than one funding source served twice as many students and had significantly more space, drop-in facilities, and relapse management policies. CRP directors had positive perceptions of harm reduction principles. Additionally, results highlighted the robust availability of All Recovery meetings and the wide diversity of mutual-help group meetings offered within CRPs and directors' positive perceptions of these meetings. This research lays a foundation for enhancing CRPs within higher education settings, emphasizing the significance of sustained funding and an inclusive support framework for the program directors that run CRPs. Future studies should further explore the effectiveness of CRPs and their impacts on the schools and students they serve.

Floor-Level Occupancy Estimation of a Multi-Story Building Using Coarse Wi-Fi Data

In recent years, there has been an extraordinary increase in wireless capable devices and network infrastructure, which spawned a corresponding rise in data produced from the interactions of these technologies. Mobile devices constantly roam, leading to a perpetual dialog between a mobile device and wireless access points. This dialogue generates a continuous stream of device-specific data, including but not limited to a device’s media access control address, time of access, and received signal strength. Given the knowledge of the access point’s location and received signal strength, it is possible to infer the position of user devices and estimate their mobility and occupancy. This article presents two methods for accurately measuring floor-level occupancy in a multi-story building at Texas State University using coarse Wi-Fi log data. The first method employs a static filter, while the second incorporates user-role data and user location to create a dynamic filter. Quantitative methods are used to evaluate these filters against field-collected reference data and existing internal people-counting sensors. Our results demonstrate that the dynamic filter, leveraging variable thresholds, provides a more accurate estimation of occupancy compared to the fixed 5-min static filter which consistently overestimated occupancy. This research sheds light on the potential of dynamic filters derived from user-role data for precise floor-level occupancy estimations, with implications for various applications.

Employing Expressive Art to Explore Mexican Americans’ Grief Experiences of Loss Due to COVID-19

The COVID-19 pandemic changed people’s lives and resulted in tremendous pain, loss and suffering. The Rio Grande Valley (RGV), in the state of Texas in the U.S., was one of the regions with the highest number of infections and deaths during the pandemic. However, individuals’ bereavement in the RGV is rarely addressed. In this qualitative study, a snowball sample of 47 individuals who had lost their loved ones during the years 2020–2021 were interviewed and invited to engage in an art activity. The findings revealed four themes: peculiar funeral, grieving confusion, loved ones’ memories, and connection to self and the lost one through art. Results indicate that the collective aspect of the funeral was disrupted during the pandemic and created emotional numbness and denial. The intensity of grieving did not decrease with time. The participants mainly relied on their family support and rarely sought professional help. A culturally adapted intervention is needed to address long-term bereavement in this community. Analysis of the art activities indicated that all participants had a feeling of peace and relief afterward, especially male participants who had difficulty expressing their emotions. The participants reported that the artwork positively affected their grievances and that the process was satisfying.

The Rise of Bromazolam in Postmortem Cases from Travis County, Texas and Surrounding Areas: 2021-2023.

As novel psychoactive substances (NPS) have continued to emerge over the last decade, NPS benzodiazepines have likewise increased in prevalence. They pose an evolving threat to public health and safety with regard to postmortem cases, particularly when used in combination with opioids. Bromazolam was first detected in Travis County, Texas (TX) in April 2021. Given the recent onset of the fentanyl epidemic in this region, the international rise of bromazolam, and increased reports of "benzo-dope", a retrospective study was conducted to characterize bromazolam-positive deaths in Travis County and surrounding counties from 2021-2023. Bromazolam was identified in 112 deaths from 2021-2023, accounting for 1.57% of cases submitted for toxicology testing (n=7,129). During that interval, a 7.5-fold increase was observed in postmortem bromazolam-related drug toxicities from 2021 (n=7) to 2023 (n=53). Fatalities primarily occurred in males in their early-30's. Postmortem concentrations ranged from 21-220 ng/mL, with mean (median) concentrations of 69.4 ± 48.4 (53.5) ng/mL. Polydrug use was present in 99% of bromazolam-positive deaths with co-occurrence with other drugs and drug classes widely varying over time. Bromazolam was attributed as the sole cause of death in one case with a postmortem blood concentration of 23 ng/mL. Polydrug use in bromazolam-related drug toxicities commonly involved fentanyl (82%), methamphetamine (41%), and cocaine (28%). Similarly, cases where bromazolam was an incidental finding and non-contributory to the cause of death often involved methamphetamine (38%), alprazolam (33%), and cocaine (33%). In light of the significant increase in fentanyl-related deaths in Travis County, the increasing prevalence of bromazolam accompanying fentanyl was particularly alarming due to the heightened risk of toxicity when used in combination. Identifying and evaluating bromazolam-related deaths clarifies the impact of bromazolam on this population, promotes awareness, and aids in identifying meaningful harm reduction strategies to decrease bromazolam-related morbidity and mortality.

American imperial exceptionalism? Texas secondary World History depictions of American empire, 1925–2016

ABSTRACT This article explores the connection between American exceptionalism and empire denialism by examining high-school World History textbooks approved for use in the state of Texas from the 1920s to 2016. Scholarship suggests that the powerful ideology of American exceptionalism is deeply uneasy about the role of the United States as an imperial power in the late nineteenth and early twentieth centuries. But despite this widespread assumption, World History textbooks for the past century have routinely labelled the United States an empire, and directly compared US actions with those of European colonising powers. Some textbooks portrayed this as a unique and aberrant time in US history. But other textbook accounts over the past century have made the case that US imperialism brought about material and political benefits to colonised peoples. In other words, a common thread in World History textbooks suggests that America created an exceptional empire. American imperialism was linked to an underlying narrative of the spread of European or Western civilisation, viewed as a cornerstone of modern world history.

Tracing Trajectories: Qualitative Visualizations of Migrant Death in South Texas, 1993–2020

Executive Summary This paper explores how qualitative information may be used to enhance understanding and inform recommendations for improved accounting of migrant deaths along the Texas-Mexico border. While border crossing related deaths affect jurisdictions throughout the US’s Southwestern border states and Northern Mexican states, Texas has unique challenges that merit specific examination. In short, the management and investigation of unidentified migrant decedents in Texas is severely fragmented and often noncompliant with Texas Criminal Code Procedure. I explore a way to improve accounting of migrant deaths leveraging qualitative information, local newspaper articles from South Texas and Northern Mexico, by using descriptive summaries coupled with Sankey Diagrams and a programmatic technique, qualitative spatial representation (QSR). QSR enabled me to identify under-recognized stakeholders (South Texas locals, Mexican consulates) and under-supported counties (i.e., those with migrant deaths that do not share a border directly with Mexico). I found that local English-language newspapers obscured the prevalence of migrant deaths and that their narrative tone of “business as usual” normalized the occurrence of such deaths. The Spanish-language articles better represented the diversity of agencies and individuals that were involved in the various aspects of migrant remains management and forensic investigation, most notably residents of South Texas themselves (or situational participants who first found the remains) and Mexican consulates. Finally, I noted that the collaborations among Texas counties and between Texan and Mexican jurisdictions, when they were described in the newspapers, highlighted that the phenomenon of migrant deaths penetrates beyond the dividing line of the Rio Grande/Río Bravo River. Migrant deaths must be accounted for in a way that reflects a regional experience in which people may perish as far as ~100 miles into Texas’ interior. Considering these observations, I have two policy recommendations. First, the Office of the Texas Governor should establish funds distinct from the Operation Lone Star program for the management of unidentified human remains. Currently, grants through the Operation Lone Star Program are the only funds available in Texas to support identification of migrant decedents. However, this program is explicitly designed to further border security operations in the state of Texas, which can contradict efforts around recovery and identification. The documentation and forensic investigation of the unidentified deceased can be eclipsed or neglected under the larger deterrence aims of Operation Lone Star. Second, to improve accounting and increase documentation of migrant deaths, a Regional Identification Center should be established in South Texas. Not every county in Texas has or has access to a Medical Examiner’s office, including the means to transport and pay for autopsy or other forensic services. The Center would provide training, store extra equipment such as mobile refrigerated morgues, and hire personnel to inventory cases, and report information to the state (e.g., vital statistics) and to foreign consulates. A Regional Identification Center would counteract the challenges highlighted in the local newspaper summaries and QSR by decreasing the isolation of counties experiencing migrant deaths and serve as a documentary and communication hub for stakeholders in Texas and Mexico.

Prioritizing social vulnerability in urban heat mitigation.

We utilized city-scale simulations to quantitatively compare the diverse urban overheating mitigation strategies, specifically tied to social vulnerability and their cooling efficacies during heatwaves. We enhanced the Weather Research and Forecasting model to encompass the urban tree effect and calculate the Universal Thermal Climate Index for assessing thermal comfort. Taking Houston, Texas, and United States as an example, the study reveals that equitably mitigating urban overheat is achievable by considering the city's demographic composition and physical structure. The study results show that while urban trees may yield less cooling impact (0.27 K of Universal Thermal Climate Index in daytime) relative to cool roofs (0.30 K), the urban trees strategy can emerge as an effective approach for enhancing community resilience in heat stress-related outcomes. Social vulnerability-based heat mitigation was reviewed as vulnerability-weighted daily cumulative heat stress change. The results underscore: (i) importance of considering the community resilience when evaluating heat mitigation impact and (ii) the need to assess planting spaces for urban trees, rooftop areas, and neighborhood vulnerability when designing community-oriented urban overheating mitigation strategies.

Compounding disaster: Perceptions of coastal risk, extreme events, and oil and gas energy production in the Gulf of Mexico

With more than five million people living in proximity to oil and gas (OGA) infrastructure, the state of Texas has the largest population at risk for developing health problems attributable to the industry in the U.S. The interaction between environmental and technological events, one kind of compound disaster events, has the potential to increase future health risks and aggravate existing social and environmental impacts. To identify current knowledge and awareness of the risks of compound disasters among residents, this article presents findings from interviews conducted in 2017 and 2019 with key stakeholders from Corpus Christi, Texas. The city is a hub of OGA production and transport and has recently suffered from the devastating effects of Hurricane Harvey. The primary set of interviews (n: 23) is also complemented by the analysis of 2 other collections (n: 20) from residents who were affected by Hurricane Harvey and which are stored at Texas A&M University-Corpus Christi's library. Findings underscore the lack of awareness of OGA activities in general and of problems related to environmental racism. We also found a normalization of the impacts of small oil incidents among respondents and biased perceptions of development. Knowledge of the risk of compound events is rare, an issue that poses significant concerns for the future of these communities and their ability to prepare and mitigate.

Probabilistic Risk Assessment of Polioencephalomalacia from Texas Beef Consuming Rations Containing Multiple Sources of Dietary Sulfur.

The purpose of this probabilistic assessment was to estimate the risk of sulfur-induced polioencephalomalacia (S-PEM) for beef raised across Texas, from a dietary perspective. Ruminant nutritionists in Amarillo, TX, formulated two typical nutritional regimens based on cattle production stages, each containing six feed ingredients and well water. The Office of the Texas State Chemist (OTSC), National Research Council (NRC), and the published literature provided S data for feed ingredients. The Texas Water Development Board provided data for S content in Texas well water, categorized into twelve districts established by the Texas A&M AgriLife Research Extension Service. The S-PEM risk was estimated at five different eNDF levels ranging from 0% to 8% in 2% increments, using rumen degradable S (RDS) as an input value. Findings identified cattle raised in the South Plains district as the most susceptible population to S toxicity, with beef in the finishing production stage experiencing increased sensitivity. The most potential (MP) risk scenario suggested that the S-PEM risk could reach 28.5% for growers and 100% for finishers. Results further revealed that when S concentrations in well water exceeded 14.5 mg/L, water became the greatest contributor to RDS content for Texas beef, suggesting that high S content in well water is the most prominent concern for Texas beef.

Muddling from the middle out: Multi-scalar governance for place-based and adaptive sustainability in Texas

Given the eclectic and localized nature of environmental risks, planning for sustainability requires solutions that integrate local knowledge and systems while acknowledging the need for continuous re-evaluation. Social-ecological complexity, increasing climate volatility and uncertainty, and rapid technological innovation underscore the need for flexible and adaptive planning. Thus, rules should not be universally applied but should instead be place-based and adaptive. To demonstrate these key concepts, we present a case study of water planning in Texas, whose rapid growth and extreme weather make it a bellwether example. We review historic use and compare the 2002, 2007, 2012, 2017 and 2022 Texas State Water Plans to examine how planning outcomes evolve across time and space. Though imperfect, water planning in Texas is a concrete example of place-based and adaptive sustainability. Urban regions throughout the state exhibit a diversity of strategies that, through the repeated 5-year cycles, are ever responding to evolving trends and emerging technologies. Regional planning institutions play a crucial role, constituting an important soft infrastructure that links state capacity and processes with local agents. As opposed to “top-down” or “bottom-up”, we frame this governance as “middle-out” and discuss how such a structure might extend beyond the water sector.

Epidemiology and control of monkeypox outbreak in Houston, Texas

BackgroundIn the 2022–2023 global outbreak, the United States and state of Texas recorded a total of 31,277 and 3,085 confirmed monkeypox (Mpox) cases respectively as of November 2023. This study aims to investigate the demographic characteristics and risk factors of Mpox outbreak in Houston and document the epidemiologic control measures implemented with their outcomes. MethodsHouston Health Department received reports of suspected Mpox cases via electronic case reports and laboratory reports from healthcare providers within Houston. These were then investigated and reclassified as either positive or negative using DNA polymerase chain reaction tests. All the reported cases received between May 2022 and January 2023 were included in this study using convenient sampling methods. Descriptive statistics using frequency distribution was used to analyze the sociodemographic, clinical features and travel history of the cases. A two-sided Chi-squared test was used to determine association between Mpox test results and risk factors with significant level set at P < 0.05. Other infection control measures such as community engagement, health education, tracking and contact tracing, vaccination, referrals and laboratory sample logistics support were implemented by the health department. ResultsOut of the total of 1,625 suspected persons investigated for Mpox, 724 (44.6%) tested positive. Among the 724 confirmed cases, male was 700 (96.7%), females 20 (2.8%), transgender male 1 (0.1%), transgender female 3 (0.4%). Age groups 30–39 years constituted 43.6%, 18–29 years 27.4%, 40–49 years 18.2%, 50–59 years was 8%. Race distribution of positive cases was Whites 43.4%, African American 38.7%, Asian 1.4%. Risk factors with P < 0.05 included male gender, age groups 30–39 years and 40–49 years, travel history to Mpox endemic areas, recent sexual contact with known or suspected Mpox cases, human immunodeficiency virus seropositivity. Identifying as gay and bisexual were also statistically significant risk factors for Mpox infection. ConclusionThe timely implementation of primary and secondary prevention measures targeted at the most at-risk populations was very effective at curtailing the spread of Mpox infection within the city of Houston.

Trends in HPV-associated cancer incidence in Texas medically underserved regions.

While cervical cancer incidence rates (IR) in the United States have dropped in the last 20 years, non-cervical human papillomavirus (HPV) associated cancers increased. Many people in Texas (TX) live in medically underserved areas and have higher risk of developing HPV-associated cancers. Since previous studies of these regions focused on cervical cancer, we included other HPV-associated cancers in our analysis of IR in East TX and the TX-Mexico Border compared to other TX regions. Cancer data from 2006 to 2019 were obtained from the TX Cancer Registry. Cases of HPV-associated cervical, vaginal, vulvar, penile, anal, and oropharyngeal cancers and corresponding patient-level demographic data were included. We calculated IR per 100,000 and drew heat maps to visualize cancer IR by county. To control potential confounders, we added county-level risk factors: rates for smoking, excessive drinking, obesity, STIs, primary care provider availability and dentist availability, from the County Health Rankings and Roadmaps program. We reported IRs by region and time and estimated unadjusted and adjusted risk ratio (RR) for association of each type of cancer and region. Lastly, we created adjusted models for each cancer by period to see time trends of regional differences. Risk of anal, cervical, and oropharyngeal cancer was lower at parts of the Border than in the rest of TX in the adjusted model. We also observed increasing anal and oropharyngeal cancer risk and decreasing cervical and vaginal cancer risk over time. Patient sociodemographics, behavioral risk factors, and access to care may contribute to some observed differences in cancer IR across regions. This indicates that targeted prevention efforts towards these regions, especially in low socioeconomic status communities, may benefit future generations.
