Recently, leadership education researchers and practitioners have raised significant concerns about the gap between the expectations of, and professional training for, leadership educators in student affairs. These professionals are frequently required to facilitate leadership learning, especially in co‐curricular training spaces for student leaders. However, they are often not adequately prepared or resourced by their professional development to deliver these training experiences. Moreover, the growing professional development opportunities in leadership education suggest practitioners need education earlier to be effective in their jobs. This article focuses on these gaps in preparing student affairs professionals as leadership educators in leadership training capacities and suggestions for future research to meet these unaddressed needs.

Objectives: We explored whether depression and anxiety moderated the association of ethnicity and neurocognitive functioning among a sample of Hispanic and non-Hispanic White rural aging adults. Method: 1,462 rural dwelling adults (Mage = 59.4 years, SDage = 12.12) were included in the analysis for this study. Results: MANCOVAs revealed a significant (ps < .001) multivariate effect of ethnicity on all five indices of neurocognitive functioning when controlling for anxiety and sociodemographic variables (V = .20, F(5,1,310) = 64.69) and depression and sociodemographic variables in the second model (V = .20, F(5,1310) = 65.80, p < .001). There was also a multivariate effect of anxiety (V = .02, F(5,1310) = 4.57, p < .001) and depression (V = .04, F(5, 1310) = 11.38, p < .001) on neurocognitive functioning when controlling for sociodemographic variables and ethnicity. Conclusion: Findings revealed that Hispanic rural aging adults scored lower on neurocognitive functioning compared to non-Hispanic White rural aging adults, irrespective of depression or anxiety. Depression and anxiety contributed to lower scores on neurocognitive functioning-yet this finding was not as robust. Culturally tailored interventions targeting risk factors for neurocognitive impairment in Hispanic rural aging adults are imperative to mitigate neurocognitive disparities. One possible reason for differences in neurocognitive functioning between Hispanic individuals and non-Hispanic individuals is stress as ethnic health disparities have been found to be shaped by a diverse range of lifetime stressors that are disproportionally exacerbated for ethnic minorities.

This study examined PK-12 teachers’ perceptions of their classroom physical learning environment and classroom climate in relation to their job satisfaction and efficacy. Previous studies suggest that teacher self-efficacy and attitudes contribute to stress, burnout, and retention rates. Using the Framework for Classroom Quality, an online survey was developed for this topic and administered to PK-12 school teachers in Oklahoma. Exploratory factor analysis was performed on data collected using 16 survey items related to the teachers perceptions of classroom physical variables, classroom climate variables, teacher efficacy and teacher perception of student characteristics. Results indicated that teacher affect and efficacy has a moderately strong, positive correlation with teacher perceptions of their classroom physical environment. Additional studies that utilize an improved survey instrument will conduct a second data collection with a new population of teachers with the aim of validating and improving the fit of the three-factor solution.

Phytoplankton have a high potential for CO2 capture and conversion. Besidesbeing a vital food source at the base of oceanic and freshwater food webs, microalgae provide acritical platform for producing chemicals and consumer products. Enhanced nutrient levels,elevated CO2, and rising temperatures increase the frequency of algal blooms, which often havenegative effects such as fish mortalities, loss of flora and fauna, and the production of algaltoxins. Harmful algal blooms (HABs) produce toxins that pose major challenges to waterquality, ecosystem function, human health, tourism, and the food web. These toxins havecomplex chemical structures and possess a wide range of biological properties with potentialapplications as new therapeutics. This review presents a balanced and comprehensiveassessment of the roles of algal blooms in generating fixed carbon for the food chain,sequestering carbon, and their unique secondary metabolites. The structural complexity ofthese metabolites has had an unprecedented impact on structure elucidation technologies andtotal synthesis, which are highlighted throughout this review. In addition, the influence ofbiogeochemical environmental perturbations on algal blooms and their influence on biospheric environments is discussed. Lastly, wesummarize work on management strategies and technologies for the control and treatment of HABs

Despite the importance of students exploring career options, developing career readiness, and experiencing a successful transition to the workforce, historically excluded populations’ participation in career development remains low. Additionally, career development professionals continue to feel unsupported in their diversity, equity, and inclusion (DEI) practices and in incorporating DEI in their respective roles. This multicase study uncovers a mirage approach to the work of career development professionals, providing opportunities to engage in this work, yet largely leaving DEI work unsupported in their quest to incorporate it into their spaces. Results indicate the larger impacts of navigating a lack of support as well as the oppressive intuitional structures that persist while engaging in DEI pedagogy and praxis.

Ticks represent important vectors of a number of bacterial and viral disease agents, owing to their hematophagous nature and their questing behavior (the process in which they seek new hosts). Questing activity is notably seasonal with spatiotemporal dynamics that needs to be understood in detail as part of mediating and mitigating tick-borne disease risk. Models of the geography of tick questing activity developed to date, however, have ignored the temporal dimensions of that behavior; more fundamentally, they have often not considered the sampling underlying available occurrence data. Here, we have addressed these shortfalls for Amblyomma americanum, the most commonly encountered tick in the central Great Plains, via (1) detailed, longitudinal sampling to characterize the spatiotemporal dimensions of tick questing activity; (2) randomization tests to establish in which environmental dimensions a species is manifesting selective use; and (3) modeling methods that include both presence data and absence data, taking fullest advantage of the information available in the data resource. The outcome was a detailed picture of geographic and temporal variation in suitability for the species through the two-year course of this study. Such models that take full advantage of available information will be crucial in understanding the risk of tick-borne disease into the future.

Efficient sampling materials are essential for assessing nicotine levels in vape shops and other settings where nicotine exposures may exist. Two different treatments of Whatman glass fiber type A (GF/A) filters (sodium bisulfate treated and citric acid treated) were evaluated for nicotine capture, desorption efficiency, and holding capacity using Gas Chromatography–Mass Spectrometry (GC–MS). The Filters were treated with 0.8 mL of 0.1 M sodium bisulfate or citric acid solution and oven-dried (80 °C) for 30 min. Nicotine was desorbed off the filters using a modified analytical method. The average nicotine desorption efficiency for sodium bisulfate-treated GF/A filters (98.4%) was significantly higher than that of citric acid-treated GF/A filters (60.9%) over a range of 1–100 µg nicotine. Sodium bisulfate-treated and citric acid-treated GF/A filters experienced a 10% nicotine breakthrough after being dosed with about 550 and 2,750 µg of nicotine, respectively compared to 75 µg for untreated GF/A filters. Citric acid-treated GF/A filters had a much greater nicotine-holding capacity, but nicotine desorption from citric acid-treated GF/A filters was below the recommended criteria. Therefore, we recommend that sodium bisulfate-treated GF/A filters are employed for sample of nicotine with the GC–MS method.

Six new species of Tricholoma (Fr.) Staude in sections Genuina (Tricholoma amarissimum, Tricholoma lutescentifolium, Tricholoma pudorinum, Tricholoma sapineum) and Fucata (Tricholoma griseobrunneum, Tricholoma pallidogriseum) are formally described from North America east of the Rocky Mountains based on their nrITS sequence, morphology, ecology, and distribution patterns. Those species are found in summer or fall in deciduous or coniferous forests. Descriptions of their morphological characters are provided, along with photographs of the basidiomata and their micromorphology. The new species are compared with similar species occurring in North America and Europe. Tricholoma felschii Ovrebo, Hughes & Halling, in section Fucata, is here considered to represent three species, T. felschii s. str., Tricholoma subumbrinum A.H. Sm., and the newly described T. griseobrunneum. Emended descriptions of the first two species are provided to accommodate the new concepts.

Opioid misuse and risk of death due to overdose are critical public health issues and young adults are at risk. College campus communities are ideal settings for the prevention of opioid misuse among young adults due to high enrollment rates, the diversity and availability of resources within the campus community, and the range of risk and protective factors that can be targeted. This practitioner narrative describes a grant-funded three-year opioid misuse prevention project implemented on a U.S. college campus. In keeping with the focus of the grant, the project involved a range of universal prevention activities implemented across the campus community. Lessons learned regarding factors that facilitated implementation in this community context are discussed and may be useful for others interested in implementing prevention activities to help prevent opioid misuse among young adults in their campus communities. Additionally, a reflection on the project and the efficacy of universal prevention to prevent opioid misuse among college students are offered for consideration.

In 1957 Abbott and Ballantine described a highly toxic activity from a dinoflagellate isolated from the English Channel in 1949 by Mary Park. From a culture maintained at Plymouth Laboratory since 1950, we have been able to isolate two toxic molecules (abbotoxin and 59-E-Chloro-abbotoxin), determine the planar structures by analysis of HRMS and 1D and 2D NMR spectra, and found them to be karlotoxin (KmTx) congeners. Both toxins kill larval zebrafish with symptoms identical to those described by Abbot and Ballantine for gobies (Gobius virescens). Using surface plasma resonance the sterol binding specificity of karlotoxins is shown to require desmethyl sterols. Our results with black lipid membranes indicate that karlotoxin forms large-conductance channels in the lipid membrane, which are characterized by large ionic conductance, poor ionic selectivity, and a complex gating behavior that exhibits strong voltage dependence and multiple gating patterns. In addition, we show that KmTx 2 pore formation is a highly targeted mechanism involving sterol-specificity. This is the first report of the functional properties of the membrane pores formed by karlotoxins and is consistent with the initial observations of Abbott and Ballantine from 1957.

In this article, we explore the process of creating spaces for the practice and inquiry of transformative listening through the development of the Transformative Listening Protocol (TLP). Our premise is that embodied listening opens doors to transformations via a process to improve listening and safe spaces where people may engage with each other in storytelling and story listening. The organization of our paper flows from research design to relevance for transformative learning theory. We begin with a description of the practice led research design for the project (Candy, 2006), we follow that with the historical development of the TLP including sections on both the theoretical and methodological background. After this section we describe the practice-ing of transformative listening with three applications of listening in practice we documented. In the final paragraphs we explore the limitations and conclusions of the research design and of TLP. We conclude the paper with the relevance of practicing transformative listening for the evolution of transformative learning theory.
