Seeing plants as never before (open access)

Seeing plants as never before

Authors of the article assert that imaging has long supported our ability to understand the inner life of plants, their development, and response to a dynamic environment. The purpose of this review was to provide the scientific community with an overview of current imaging methods, which rely variously on either nuclear magnetic resonance (NMR), mass spectrometry (MS) or infrared (IR) spectroscopy, and to present some examples of their application in order to illustrate their utility.

Gemini Near Infrared Spectrograph–Distant Quasar Survey: Augmented Spectroscopic Catalog and a Prescription for Correcting UV-based Quasar Redshifts (open access)

Gemini Near Infrared Spectrograph–Distant Quasar Survey: Augmented Spectroscopic Catalog and a Prescription for Correcting UV-based Quasar Redshifts

Article describes how quasars at z ≳ 1 most often have redshifts measured from rest-frame ultraviolet emission lines. One of the most common such lines, C ivλ1549, shows blueshifts up to ≈5000 km s−1 and in rare cases even higher. The authors present spectroscopic measurements for 260 sources at 1.55 ≲ z ≲ 3.50 having −28.0 ≲ Mi ≲ − 30.0 mag from the Gemini Near Infrared Spectrograph–Distant Quasar Survey (GNIRS-DQS) catalog, augmenting the previous iteration, which contained 226 of the 260 sources whose measurements are improved upon in this work.

Testing Family Functioning and Psychosis Risk Across Race and Ethnicity

Family functioning has long been a focus of research in psychopathology. Decades of research has shown that family factors are associated with symptom severity, relapse, functional outcomes, and conversion to psychosis among at-risk individuals. Previous studies suggest family functioning varies across cultures, which raises the possibility that associations between family factors and psychopathology may also differ by culture. Furthermore, family functioning assessment generally involves instruments that have not been systematically validated for use with individuals from diverse cultural backgrounds. The current study used data from the Adolescent Brain Cognitive Development study (N = 11,138) to: (1) evaluate three family functioning scales (i.e., Family Environment Scale, Child's Report of Parental Behavior Inventory, Parental Monitoring Survey) and the Prodromal Questionnaire – Brief Child version for measurement invariance across racial/ethnic groups; (2) investigate the relations between family factors and psychosis; and (3) compare relations derived from Step 2 between racial/ethnic groups. Full scalar invariance was tenable for the CRPBI and the PQ-BC, providing statistical support for mean comparisons across groups. The FES and the PMQ lacked scalar invariance, which suggests mean comparisons across groups may not be appropriate. The CRPBI and the PMQ are significantly associated with the PQ-BC, and all three family …

Effects of Hypoxia Responses during Moderate- and Severe-Intensity Exercise Performed to Exhaustion

The purpose of the study was to investigate the effects of hypoxia responses during moderate- and severe-intensity exercise performed to exhaustion. Nine healthy university students, five men, and four women (mean ± SD, age, 23 ± 1 y; height 167 ± 8 cm; weight 73 ± 7 kg) performed a cycle ergometer test in normoxia and hypoxia conditions. Cardiorespiratory, metabolic, and perceptual responses were measured during moderate-intensity and during severe-intensity exercise. During moderate-intensity exercise, hypoxia exaggerates the cardiorespiratory and ventilatory responses and delays the attainment of the steady state VO2 kinetics. However, during severe-intensity exercise, compensatory responses were not adequate, oxygen demand was slightly increased and VO2 max was reduced in hypoxia affecting the overall performance. Therefore, the greater reliance on the anaerobic pathways could have a serious implication on the performance of the exercise over a wide range of intensities.

Neurotoxic Effects of Polycyclic Aromatic Hydrocarbons in Vertebrates, from Behavioral to Cellular Levels

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental toxicants found in anthropogenic mixtures such as crude oil, air pollution, vehicle exhaust, and in some natural combustion reactions. Single PAHs such as benzo[a]pyrene (BaP) also impact fish behavior when animals are exposed in early life stages and for short periods of time. Aquatic animals such as fish may encounter BaP through road runoff and oil spills, but few studies have examined the impact of aqueous exposure on adult fish, and fewer have examined the resulting fitness-relevant behavioral consequences of BaP and PAH mixtures and their long-term persistence. This dissertation targets this gap in the literature by examining how aqueous exposure to BaP influences anxiety-like behavior, learning, and memory in adult zebrafish, and how parental exposure to the PAH mixture, crude oil, combined with hypoxia affects social and exploratory behavior in unexposed larval zebrafish. We found that learning and memory were not affected by 24 hour exposure to BaP, that anxiety-like behavior was minimally affected, and that locomotor parameters such as distance moved and times spent in darting and immobile states were significantly altered by exposure to BaP. Additionally, we found that parental exposure to crude oil and hypoxia decreased larval velocity. Additionally, …

Archive Activism: Memoir of a "Uniquely Nasty" Journey

Access: Use of this item is restricted to the UNT Community
Archive Activism is a memoir of activism rooted in a new way to converse with history—by rescuing it. Archive activists discover documents and other important materials often classified, “gone missing,” or sealed that somehow escaped the fireplace or shredder. It is an approach to LGBTQ advocacy and policy activism based on citizen archivery and original archival research to effect social change. Research=Activism is the formula growing out of Charles Francis’s personal story as a gay Texan born and raised during the 1950s and 1960s in Dallas. The rescues range in time and place from Francis’s first encounter with a raucous, near-violent religious demonstration in Fort Worth to attics loaded with forgotten historic treasures of LGBTQ pioneers. Archive Activism tells how Francis helped Governor George W. Bush achieve his dream of becoming president in 2000 by reaching out to gay and lesbian supporters, the first time a Republican candidate for president formally met with gay and lesbian Americans. This inspired Francis to engage with deleted LGBTQ history by forming a historical society with an edge, a new Mattachine Society of Washington, DC. For the first time, Archive Activism reveals how LGBTQ secrets were held for decades at the LBJ Presidential Library …

CEDAR: The Life and Music of Cedar Walton

Access: Use of this item is restricted to the UNT Community
Grammy Award–winning pianist, bandleader, and composer Cedar Walton (1934–2013) is a major figure in jazz, associated with a variety of styles from bebop to funk and famous for composing several standards. Born and raised in Dallas, Walton studied music in Denver, where he jammed with musicians such as Charlie Parker and John Coltrane. In 1955, Walton moved to New York, immediately gaining recognition from notable musicians and nightclub proprietors. When Walton returned to the U.S. after serving abroad in the Army, he joined Benny Golson and Art Farmer’s Jazztet. Later, he became both pianist and arranger for Art Blakey’s Jazz Messengers. Next, he worked as part of Prestige Records’s house rhythm section, recording with numerous greats and releasing his own albums. One hallmark of Walton’s impact is his numerous long-term collaborations with giants such as trombonist Curtis Fuller and drummer Billy Higgins. By the end of his career, Walton’s discography, as both band member and bandleader, included many dozens of vaunted recordings with some of the most notable jazz musicians of the 1960s through the first decade of the twenty-first century. Ben Markley conducted more than seventy-five interviews with friends and family members, musicians who played with or were otherwise …

Supply Chain Transparency from a Stakeholder's Perspective: Analyzing the Risks and Benefits of Supply Chain Information Disclosure

Supply chain transparency is principally focused on a company's efforts toward disclosing information about their products, and their supply chain operations to the public. Essay 1 is a conceptual paper that examines the risks of disclosing supply chain mapping information to consumers and proposes an approach to developing risk mitigation strategies. This essay also develops a set of supply chain mapping conventions that support the development of an agility-focused supply chain map. Essay 2 employs an experimental design methodology to examine the impact of disclosing the ethnicity of a supplier on consumers' behaviors, while also capturing the extent to which a consumers' ethnic identity and prosocial disposition influence their behaviors. Finally, also using an experimental design, Essay 3 analyzes consumer outcomes based on disclosing no, partial, and full supply chain transparency information, and accounts for heterogenous consumer traits such as the importance of information to a consumer and their perceived quality of information. Collectively, these essays advance the body of knowledge that seeks to understand the risks and benefits of supply chain transparency, by conceptually identifying risks and proposing an approach to minimize the risks associated with supply chain transparency, and by illuminating the conditions that prompt favorable consumer outcomes.

Leadership Support for Teachers' Classroom Management and Student Behavior Professional Learning (open access)

Leadership Support for Teachers' Classroom Management and Student Behavior Professional Learning

Student behavior and classroom management are consistently identified as top reasons teachers leave the profession. A descriptive phenomenological study was conducted in a suburban school district in north Texas to identify how teachers perceive the deficits in their classroom management knowledge and to provide school leaders with data to guide plans for professional learning about effective classroom management strategies. Findings are based on both teachers' and principals' perceptions of supports that are needed or provided. Nine teachers (three elementary, three middle, and three high school) and six administrators (two elementary, two middle, and two high school) were interviewed using semi-structured interview protocols. Data were analyzed using seven a priori codes from which themes were developed. The findings showed that teachers generally do not feel well-prepared to address student behavior and classroom management. Emerged themes from both teacher and principal interviews identified deficits in professional learning received from their teacher preparation program, campus leaders, and district leaders. The top reasons why teachers struggled with student behavior and classroom management were: (a) application of learning, (b) deficits in support, (c) deficits in training, (d) physical and emotional toll, and (e) student deficits in social skill development. To help teachers feel better prepared …

Musique Concrète Instrumentale in Helmut Lachenmann's "Child's Play" (1980): A Pedagogical Study for Late Intermediate Students (open access)

Musique Concrète Instrumentale in Helmut Lachenmann's "Child's Play" (1980): A Pedagogical Study for Late Intermediate Students

Helmut Friedrich Lachenmann is a German composer of contemporary music. In his 1980 work for piano, Child's Play, Lachenmann develops one of his own signature concepts, musique concrète instrumentale, in which he uses the "standard" (not prepared) piano in non-conventional and innovative ways to explore new sounds and techniques. This dissertation is a pedagogical study that provides a teaching guide for educators who would like to use Child's Play as an introduction to some of the sounds and techniques of contemporary music for their late intermediate students. In order for educators to effectively guide their students through Child's Play, they should understand the sonorities of musique concrète instrumentale as well as the extended techniques it requires. This dissertation addresses those needs through three principal means. First, it introduces Lachenmann's musique concrète instrumentale and classifies the various sonorities into three types: descriptive, contrasting, and extended. Second, it analyzes and discusses technical elements in the cycle, including notational considerations, pedaling, and sound effects. Last, the dissertation provides pedagogical suggestions to help students master these technical elements. By studying and playing this piece, students not only become intimately familiar with some of the many sounds they are able to produce on the piano, …

Linguistic Racism in the Marketplace

Linguistic racism is faced by non-native customers due to their different language style when they go through the service exchange process. Despite its prevalence and importance, there is a dearth of research about linguistic racism in the marketing literature, especially from consumers' perspectives. This dissertation thus aims to address this gap by focusing on consumers' cognitive and affective responses as a result to their linguistic racism experiences when they interact with service employees (native speakers) from the host country. Toward this goal, first (Essay 1), a qualitative study is performed to anchor the dissertation in the customers' real-life experiences and to help identify key associated themes which are further empirically examined (Essay 2 & 3) in this three-essay format dissertation. Essay 2 empirically investigates if the identity assignment through ones' language style makes customers feel stigmatized and influence their psychological well-being. In addition, how these experiences subsequently influence their inclination to use technology-mediated interfaces. Similarly, the main objective of Essay 3 was to employ a sociological perspective to examine the impact of language-based chronic social exclusion on non-native customers' psychological and behavioral responses in the marketplace. Moreover, their intention to pay higher tip as a refocusing strategy when these customers …

Adoption of Innovation in a Community College Environment: User Perceptions of Virtual Reality (VR) Technology among Students Studying Emergency Medical Service (EMS)

This research study examined the implementation of an extended reality (XR) lab on a community college campus to facilitate student and faculty access to immersive learning resources. The study, conducted during one skills day, involved 46 students and was designed to understand if integrating immersive VR into emergency medical technician (EMT) education could enhance learner confidence and motivation, develop problem-solving and analytical thinking skills, and thus connecting the classroom learning with real-world application. The majority of participants reported increased motivation and engagement, alongside improvements in learning outcomes like knowledge retention and skill development. Applying the unified theory of acceptance and use of technology (UTAUT) model revealed performance expectancy, effort expectancy, social influence, and facilitating conditions as key determinants of VR adoption in EMT education. While no significant overall performance enhancement was observed, VR training showed potential to boost motivation, confidence, and specific performance aspects. Furthermore, student perceptions towards VR in EMT education were largely positive, thereby suggesting its utility in immersive scenario training, skill acquisition in a risk-free environment, enhancing learner engagement, and real-world situational preparedness. VR demonstrated promise as a transformative tool in EMT education, necessitating further research to fully exploit its potential in diverse learning environments.

Using Curriculum Mapping to Understand Information Literacy in Political Science Curricula

Article presenting a curriculum mapping study of noncore course offerings in political science curricula by an early-career librarian. It combines syllabi study and curriculum mapping methods to analyze the language of student learning objectives (SLOs) from course syllabi and to integrate SLOs with threshold concepts from the ACRL Framework for Information Literacy for Higher Education and the AAC&U Information Literacy VALUE Rubric. The methods produce two sample sets: one of core concept representation and the other of additional observances for syllabi improvements. Results analyze the frequency and percentage distributions of threshold concepts in SLOs. The author outlines strategies for engaging faculty in information literacy and suggests how librarians and faculty might inform information literacy teaching in the department.

Selection Bias and Sensitivity as Moderators of Prekindergarten Age-Cutoff Regression Discontinuity Study Effects: A Meta-Analysis

The age-cutoff regression discontinuity design (RDD) has emerged as one of the most rigorous quasi-experimental approaches to determining program effects of prekindergarten on literacy and numeracy outcomes for children at kindergarten entry. However, few pre-K meta-analyses have focused attention on validity threats. The current random-effects meta-regression tests the moderating effects of prominent threats to validity, selection bias and sensitivity, on impact estimates generated from age-cutoff regression discontinuity studies from large-scale programs. Results from averaging dependent standardized mean difference effects suggested small positive moderating effects of total attrition and robust 3-month bandwidths on reading effects, but not on math. However, these results were not statistically significant. In contrast, results generated from robust variance estimation yielded a small statistically significant association between total attrition and math effects. These mixed results may warrant further research on prekindergarten evaluation methodology, evaluation estimation methods, and the totality of evidence used to inform policy.

Renewable Electricity in DFW: Access, Distribution, and Consumer Awareness (open access)

Renewable Electricity in DFW: Access, Distribution, and Consumer Awareness

Texas is the leading producer of renewable energy in the U.S, and Dallas-Fort Worth (DFW) is the largest metropolitan area in the state. Texas has a deregulated energy market, with three types of providers: privatized, public-owned, and co-operatives. Privatized providers compete in the deregulated market, and consumers choose between hundreds of electricity retailers. Public-owned providers are owned by the municipality, and electricity consumers that live within the city limits must use the municipal provider. Electric co-operatives operate similarly where customers within the region must use the co-operative, but instead of being owned by the city, co-ops are owned by the members (customers). To date, the availability, cost, accessibility, and outreach of renewable electricity among these provider types remains unclear. For this reason, my research examines the renewable energy market in DFW by asking: (1) Who has access to renewable energy and how do they understand it? (2) How do electricity retailers distribute and make renewable energy available? and (3) If consumers can choose their provider, why do they select certain electricity plans over others? My findings suggest that while many consumers want or are open to using renewable energy, uncertainties surrounding how to find or choose a provider, price, and …
