- Abstract
Responding to the needs of writers, teachers, students, and scholars using the MLA style of documentation, professional organizations and researchers are in the process of creating citation conventions that seek to, demonstrate efficient and unambiguous reference to Internet sources. Going beyond the limited recommendations in, The MLA Handbook for Writers of Research Papers (1995), Janice Walker's "MLA-Style Citations for Electronic, Sources," for example, presents a largely admirable style for documentation, worthy of endorsement by the Alliance, for Computers and Writing. In spite of its usefulness, however, a close examination of the style reveals several, noteworthy ambiguities and infelicities. Four problematic areas can be identified: (1) distinguishing between, Internet addresses and command sequences, (2) distinguishing between dates of publication and dates of user access, (3) distinguishing between addresses of publication and addresses for retrieval, and (4) providing for the "openness", of many Internet pathways to the same (authentic) source. After examining each of the four problem areas, we, recommend additions and emendations to Walker's models that help eliminate ambiguities. Each of our, recommendations improves the usefulness and clarity of individual models. Finally, in "Citing the Sites: MLA-Style, Guidelines and Models for Documenting Internet Sources," we provide a style sheet for teachers, students, researchers, and scholars whose citation standards are based on MLA-style documentation principles and models., "Citing the Sites" may be distributed as a self-contained guideline providing checklists and models for all current, instances of Internet citation.

International audience; Pantelleria volcano has a particularly intriguing evolutionary history intimately related to the peralkaline composition of its explosively erupted magmas. Due to the stratigraphic complexity, studies over the last two decades have explored either only the pre-Green Tuff ignimbrite volcanism or the post-Green Tuff activity. We here focus on the whole evolutionary history, detailing the achievements since the first pioneering studies, in order to illustrate how the adoption and integration of progressively more accurate methods (40 Ar/ 39 Ar, paleomagnetism, petrography, and detailed field study) have provided many important independent answers to unresolved questions. We also discuss rheomorphism, a distinct feature at Pantelleria, at various scales and possible evidence for multiple, now hidden, caldera collapses. Although the evolutionary history of Pantelleria has shown that each ignimbrite event was followed by a period of less intense explosivity (as could be the present-day case), new geochronological and geochemical data may indicate a long-term waning of volcanic activity.

Crystallization experiments on two pantellerites from Pantelleria, Italy, provide new evidence for the relationships between mineral phases in pantelleritic rocks as well as the influence of temperature and redox conditions on mineral assemblages. Experiments were performed at 1 kbar with temperature ranging between 750–900°C, and fluid saturation conditions with XH2O (=H2O/H2O+CO2) between 0 and 1. Redox conditions were fixed at, or slightly below, the FMQ buffer. Results show that at temperature of 900 °C pantelleritic magmas are well above the liquidus regardless their water content; we also observed a decrease in liquidus temperature (800°C) with increasingly reducing conditions. Mineral assemblages of the natural rocks have been successfully reproduced, particularly the relationship between fayalite and aenigmatite, which appear to be strongly controlled by melt peralkalinity, temperature and redox conditions. This is the first time that fayalitic olivine have been synthetized in experimental studies on pantellerites, which was found to be stable only for temperatures ≥750°C while amphibole can be stable at temperatures as high as 800°C at high fF2. Experimental results have been compared with the composition of mineral phases as well as with the results obtained from mineral equilibrium, geothermometry, and oxygen barometry studies on pantelleritic lava and tuffs from Pantelleria (Italy), Eburru (Kenya) and Menengai (Kenya). Petrological characteristics appear similar at different locations worldwide, with typical assemblages of anorthoclase and sodian clinopyroxene with variable fayalite, aenigmatite, Fe-Ti oxides and amphibole.

International audience; The island of Pantelleria is one of the best known localities of bimodal mafic-felsic magmatism (alkali basalt and trachyte-pantellerite). Among the felsic rocks, the coexistence in a single eruption of products of both trachyte and pantellerite compositions is limited to few occurrences, the Green Tuff (GT) ignimbrite being one of these. The GT is compositionally zoned from pantellerite (70.1 wt% SiO2, mol Na+K/Al = 1.86, 1871 ppm Zr) at the base to crystal-rich (>30 vol%) comenditic trachyte (63.4 wt% SiO2, mol Na+K/Al = 1.10, 265 ppm Zr) at the top, although the pantellertic compositions dominate the erupted volume. We present here new data on melt inclusions (MIs) from the pantellerite portions of the GT eruption and, most importantly, from the trachyte member, which have not been studied in-situ by previous work focused on the GT. We document the first occurrence of trachytic melt inclusions in the late-erupted member, whose im-portance resides in the fact that trachytes were known mostly as crystal-rich lavas or ignimbrites, all variably affected by crystal accu-mulation. Besides the obvious inferences on the interplay between parental-derivative magmas, this evidence adds also some helpful ele-ments in understanding zoning of silicic and peralkaline (i.e. low-viscosity) magma chambers. Trace elements compositions of MIs reveal that trachyte melts are of two types: (i) a low-Ba, directly descending from basaltic melts by 60-70 % of fractional crystallisation, and (ii)a high-Ba that might be affected by processes of feldspar dissolution and entrainment of the resulting small-scale melts in some MIs. MIs hosted in the deep-seated trachyte body are H2O-poor (≤ 1.2 wt %) with respect to the early erupted (and shallower) pantellerite magma(≤ 4.2 wt %), raising the possibility that either trachyte magma was H2O-undesaturated, or clinopyroxene hosted melt inclusions whichsuffered consistent H2O loss.

article number 1750161; International audience; Given a finite ring $A$ which is a free left module over a subring $R$ of $A$, two types of $R$-bases are defined which in turn are used to define duality preserving maps from codes over $A$ to codes over $R$. The first type, pseudo-self-dual bases, are a generalization of trace orthogonal bases for fields. The second are called symmetric bases. Both types are illustrated with skew cyclic codes which are codes that are $A$-submodules of the skew polynomial ring $A[X;\theta]/\langle X^n-1\rangle$ (the classical cyclic codes are the case when $\theta=id$). When $A$ is commutative, there exists criteria for a skew cyclic code over $A$ to be self-dual. With this criteria and a duality preserving map, many self-dual codes over the subring $R$ can easily be found. In this fashion, numerous examples are given, some of which are not chain or serial rings.

International audience; Reconstructing the origin and evolution of land plants and their algal relatives is a fundamental problem in plant phylogenetics, and is essential for understanding how critical adaptations arose, including the embryo, vascular tissue, seeds, and flowers. Despite advances in molecular systematics, some hypotheses of relationships remain weakly resolved. Inferring deep phylogenies with bouts of rapid diversification can be problematic; however, genome-scale data should significantly increase the number of informative characters for analyses. Recent phylogenomic reconstructions focused on the major divergences of plants have resulted in promising but inconsistent results. One limitation is sparse taxon sampling, likely resulting from the difficulty and cost of data generation. To address this limitation, transcriptome data for 92 streptophyte taxa were generated and analyzed along with 11 published plant genome sequences. Phylogenetic reconstructions were conducted using up to 852 nuclear genes and 1,701,170 aligned sites. Sixty-nine analyses were performed to test the robustness of phylogenetic inferences to permutations of the data matrix or to phylogenetic method, including supermatrix, supertree, and coalescent-based approaches, maximum-likelihood and Bayesian methods, partitioned and unpartitioned analyses, and amino acid versus DNA alignments. Among other results, we find robust support for a sister-group relationship between land plants and one group of streptophyte green algae, the Zygnematophyceae. Strong and robust support for a clade comprising liverworts and mosses is inconsistent with a widely accepted view of early land plant evolution, and suggests that phylogenetic hypotheses used to understand the evolution of fundamental plant traits should be reevaluated.

International audience; The 1,000 plants (1KP) project is an international multi-disciplinary consortium that has generated transcriptome data from over 1,000 plant species, with exemplars for all of the major lineages across the Viridiplantae (green plants) clade. Here, we describe how to access the data used in a phylogenomics analysis of the first 85 species, and how to visualize our gene and species trees. Users can develop computational pipelines to analyse these data, in conjunction with data of their own that they can upload. Computationally estimated protein-protein interactions and biochemical pathways can be visualized at another site. Finally, we comment on our future plans and how they fit within this scalable system for the dissemination, visualization, and analysis of large multi-species data sets.

- Abstract
This study investigated whether the relationship between perceived health and somatic anxiety is moderated by religious involvement among a sample of Hispanic Seventh-day Adventists (n = 365) during the COVID-19 pandemic. Using PROCESS moderation analysis, we examined the interaction between perceived health and religious involvement on somatic anxiety. Results indicated a significant interaction effect, suggesting that the inverse relationship between perceived health and somatic anxiety was stronger when religious involvement was present., Competing Interests: Declarations.

NTR ) is a multifunctional transmembrane protein that mediates neuronal responses to pathological conditions in specific regions of the nervous system. In many biological contexts, p75NTR signaling is initiated through sequential cleavage of the receptor by α- and γ-secretases, which releases receptor fragments for downstream signaling. Our previous research demonstrated that proteolytic processing of p75NTR in this manner is stimulated by oxidative stress in Lund Human Mesencephalic (LUHMES) cells, a dopaminergic neuronal cell line derived from human mesencephalic tissue. Considering the vulnerability of dopaminergic neurons in the ventral mesencephalon to oxidative stress and neurodegeneration associated with Parkinson's disease (PD), we investigated the role of this signaling cascade in neurodegeneration and explored cellular processes that govern oxidative stress-induced p75NTR signaling. In the present study, we provide evidence that oxidative stress induces cleavage of p75NTR by promoting c-Jun N-terminal Kinase (JNK)-dependent internalization of p75NTR from the cell surface. This activation of p75NTR signaling is counteracted by tropomyosin-related kinase (Trk) receptor signaling; however, oxidative stress leads to Trk receptor downregulation, thereby enhancing p75NTR processing. Importantly, we demonstrate that this pathway can be inhibited by LM11a-31, a small molecule modulator of p75NTR , thereby conferring protection against neurodegeneration. Treatment with LM11a-31 significantly reduced p75NTR cleavage and neuronal death associated with oxidative stress. These findings reveal novel mechanisms underlying activation of p75NTR in response to oxidative stress, underscore a key role for p75NTR in dopaminergic neurodegeneration, and highlight p75NTR as a potential therapeutic target for reducing neurodegeneration in PD., (© 2025 International Society for Neurochemistry.)- Published

- Abstract
Aims: The purpose of the study was to explore youth gymnastics coaches' perceptions on inclusive sports participation following an educational module. The study aims to explore implications for occupational therapy professionals' role in inclusive sports., Methods: A qualitative descriptive approach was utilized with convenience sampling occurring through online platforms. Nine participants completed an educational module on autism spectrum disorder including strategies to promote inclusion in sports and address sensory and motor issues, prior to completing a semi-structured interview. Interviews were transcribed and coded prior to the determination of themes with triangulation and member checking employed., Results: Thematic analysis resulted in the following themes: (1) occupational engagement in sports benefits both neurodiverse and neurotypical children; (2) sociocultural and physical environments create barriers to autistic youth's participation in sports; and (3) grace and knowledge enhance coaches' ability to promote inclusive occupational participation in sports for autistic youth. Themes were representative of the interconnected occupational components impacting inclusive sports of which occupational therapists are poised to address., Conclusion: Lack of participation in sports for all children and children with disabilities is a complex system of physical, social, psychological, cultural, and environmental elements. Occupational therapists are equipped to educate youth sports providers and demonstrate leadership in advocating for inclusive sports programs to facilitate equitable sports participation, health, and wellness for children.

- Abstract
Soccer is a sport being performed in a very dynamic manner. It requires soccer players to be able to develop high muscle force in a very short period of time. The aim of the study was to evaluate the strength and jumping abilities of young soccer players playing in different positions on the field. The study included 49 adolescent soccer players: 6 goalkeepers, 15 defenders, 17 midfielders and 11 strikers. We measured peak torques (PT), total work (TW), and average power (AP) developed by the knee flexors and extensors under isokinetic conditions at angular velocities of 60°⋅s
-1 , 180°⋅s-1 and 300°⋅s-1 on a Biodex dynamometer, and jump height ( H ) and maximum power ( Pmax ) on a force plate. PT, AP, TW, and Pmax scores were normalized relative to body mass. There were no statistically significant differences between measurements of basic somatic characteristics (body height and body weight), age and biological age as well as PT, AP, TW, H, and Pmax in players from different positions on the field. Unlike defenders, midfielders showed a significant correlation of isokinetic tests indices with jump height ( r = 0.54÷0.84) and maximum relative power ( r = 0.55÷0.76). The differences in correlations are probably due to the different tasks and activities that players in different positions on the field perform during the game., (© 2024 Michał Górski et al., published by Sciendo.)- Published

- Abstract
While occupation began as the central concept of occupational therapy at the dawn of the profession, the use of occupation throughout the therapy process, including assessment, has wavered in recent decades. Occupation is defined as meaningful and purposeful activities that individuals do to occupy their time and attention. The use of occupation-based assessments is vital to establishing care with an occupational focus. The purpose of this article is to review the outcome assessment tools commonly used in the burn literature to evaluate hand function and critique the presence of occupation in each assessment using the Occupation-Based Practice Assessment. Knowledge of the occupational nature of assessments is important to the delivery of an occupational therapy evaluation comprised of a battery of assessments inclusive of discrete measures of movement as well as performance-based tools to represent the person from an occupational perspective. Many outcome measures used in upper extremity burn rehabilitation are discrete in nature and do not measure occupations of clients. The Suitcase Packing Activity may be a viable addition to an assessment battery to address this essential need., (Published by Oxford University Press on behalf of the American Burn Association 2024.)

- Abstract
The nature of western lowland gorilla social relationships within and between groups is largely understudied, partly due to the challenges of monitoring associations between individuals who live in neighboring groups. In this study, we examined the social relationships of four western lowland gorilla groups in the Ndoki landscape of northern Republic of Congo. To do so, we compiled all-occurrence social interaction and silverback nearest neighbor social networks from data collected during daily group follows conducted over several years. We observed a total of 5,923 dyadic all-occurrence social interactions (1,350 ± 489 per group, 138 intergroup interactions) and 54,989 dyadic silverback nearest neighbor associations (13,747 ± 3,963 observations per group, 105 nearest neighbor observations of intergroup partners during group scans). For all groups, we found that males were more social than females, younger individuals were more social than older gorillas, and slightly greater rates of social behaviors were observed during periods of higher fruit availability. While there was a considerable amount of interindividual variation in social behavior, the network of social interactions demonstrated a large extent of social relationships within and between groups. Additionally, we performed simulated network removals to assess the impact on social dynamics. Across all groups and the total population, the removal of blackback and immature individuals markedly decreased the number of intra- and intergroup relationships (>60% decrease). The documented extent of western lowland gorilla social relationships has direct implications for the conservation of species with multi-level social dynamics. Gaining clarity on the ways in which western lowland gorilla groups naturally occur in the wild, not only provides a greater understanding for their conservation, but also offers insights for managing their social dynamics within captive environments., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2025 Cooksey et al.

Bernhard FB, Howell DM, and Bray L
- Abstract
The purpose of this paper is to propose the Intentional and Attuned Therapeutic Relationship Model as a means to emphasize an intentional and attuned therapeutic relationship among the therapist, autistic child, and their caregiver. Neurodiversity-affirming practice is strengths-based, collaborative, and inclusive of the needs and goals of the autistic child and their caregiver. As this necessitates reevaluating occupational therapy models of care delivered to autistic children, this paper provides a brief review of sensory processing and emotional regulation; discusses the Intentional Relationship Model and the phenomenon of attunement, respectively; and proposes the Intentional and Attuned Therapeutic Relationship Model, which combines elements of the Intentional Relationship Model and attunement to develop the therapeutic relationship in alignment with the neurodiversity-affirming paradigm.

- Abstract
Objective: Examine factors contributing to high rates of Appalachian female cancer incidences and mortalities by examining cancer literacy and associated sociological influences among Appalachian university students., Participants: This study evaluated Appalachian and non-Appalachian undergraduate students in Eastern Kentucky., Methods: A Qualtrics survey was disseminated which categorized questions into three parts: demographic, female focused cancer literacy, and cancer care access., Results: Overall cancer literacy was low (67.45%, 139 respondents); no difference was found in Appalachian standing. Male students had lower scores (p < 0.05), and both cancer-related majors (p < 0.001) and enhanced academic years (p < 0.05) improved cancer literacy. Limited awareness of mobile cancer screening units was found across respondents, along with, decreased access to health services indicated by Appalachian students (p < 0.05)., Conclusions: College students represent a population in need of enhanced cancer education. Improving knowledge about accessing healthcare including cancer screenings could reduce Appalachian cancer rates.

25. Sulfites and sulfates formed by weathering of early martian carbonates in a sulfur dioxide-bearing atmosphere.

Chevrier VF, Gil-Lozano C, Dehouck E, and Altheide ST
- Abstract
Despite ample evidence that extensive water-rock interactions occurred under a CO
2 -dominated atmosphere on early Mars, carbonate minerals are relatively rare at the surface. One possibility to explain this scarcity is that carbonates were initially abundant, but were later destroyed when atmospheric conditions changed, particularly as a result of volcanism releasing large volumes of sulfur dioxide SO2 into the atmosphere. However, despite some early theoretical and experimental results, no study has investigated the stability of the most common carbonates (Ca, Mg and Fe) in the presence of abundant SO2 gas. Here we present the results of experiments demonstrating that carbonates are systematically unstable when exposed to 0.8 bar of SO2 in moderately oxidizing (SO2 + H2 O) or strongly oxidizing (SO2 + H2 O + H2 O2 ) environments. In both environments, the reaction end products are systematically sulfates, except for calcium carbonate, which predominantly transforms into calcium sulfite (hannebachite) in moderately oxidizing conditions. Based on these results, carbonates formed early in martian history would have been rapidly decomposed and replaced by sulfates (and sulfites if calcium was abundant enough) in the presence of abundant SO2 released by major volcanic events such as those associated with the build-up of the Tharsis rise., Competing Interests: Declarations.

- Abstract
Objectives: To understand college and university student knowledge, attitudes, and behaviors (KAB) regarding COVID-19 prevention strategies. Methods: Thirteen colleges and universities volunteered to conduct an anonymous electronic survey in April 2021 to assess students' KAB about mask use and vaccination to prevent COVID-19. Results: Three-quarters of students indicated they "Always" wore a mask correctly when in public indoor places. Of those not yet vaccinated, 55% expressed concern about unknown side effects. Over half of students were unsure or believe they do not need to continue wearing masks after vaccination and older students more likely to be vaccinated. There was a significant inverse correlation between intention of getting vaccinated and intention to attend a large indoor party without a mask. Conclusions: Colleges and universities are important to community efforts to slow the COVID-19 pandemic. The KAB findings can inform approaches to increase overall mask use and vaccination uptake among young students.

Shin M and Park J
- Abstract
This study examines the effects of technology-assisted instruction with teacher prompts on the ability to visualize and solve fraction multiplication word problems for four middle school students with learning disabilities. A multiple-probe design across participants, a type of single-case design, showed a functional relationship between the intervention and the targeted mathematical outcomes. Although there were some fluctuations over time, students demonstrated improvements from the baseline to intervention phases (Tau ranged from 0.76 to 1.00 for visualization and was 1.00 for problem-solving). Researchers employed Bayesian cumulative link mixed effects models to examine the moderating effects of word problem question types. Students showed greater maintenance effects on problem-solving than on visualization tasks, as reflected in changes in level (logit coefficient = 2.6) and trend (logit coefficient = 0.22). Students and teachers perceived vocabulary and multiplication fact practices, as well as the cognitive and metacognitive features embedded in the technology-assisted intervention, to be useful in learning targeted mathematics concepts. This study underscores the role of technology integration in enhancing teachers' instructional approach and in aiding students' acquisition and retention of mathematical concepts and skills.

- Abstract
Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in the ecosystems they occupy. Understanding the global distribution of these animals is often hindered due to a paucity of distributional data. Additionally, non-native crayfish introductions are becoming more frequent, which can cause severe environmental and economic impacts. Management decisions related to crayfish and their habitats require accurate, up-to-date distribution data and mapping tools. Such data are currently patchily distributed with limited accessibility and are rarely up-to-date. To address these challenges, we developed a versatile e -portal to host distributional data of freshwater crayfish and their pathogens (using Aphanomyces astaci , the causative agent of the crayfish plague, as the most prominent example). Populated with expert data and operating in near real-time, World of Crayfish ™ is a living, publicly available database providing worldwide distributional data sourced by experts in the field. The database offers open access to the data through specialized standard geospatial services (Web Map Service, Web Feature Service) enabling users to view, embed, and download customizable outputs for various applications. The platform is designed to support technical enhancements in the future, with the potential to eventually incorporate various additional features. This tool serves as a step forward towards a modern era of conservation planning and management of freshwater biodiversity., Competing Interests: The authors declare there are no competing interests., (©2024 Ion et al.)

- Abstract
Introduction: Breastfeeding intention is one of the strongest predictors of breastfeeding behavior and practice. The Theory of Planned Behavior (TPB), with its main construct, behavioral intention, is useful to predict actual behavior. While the literature has examined the implications of other theoretical notions such as self-identity, moral norm, descriptive norm, and socio-demographic variables, their roles remain unclear. Similarly, research on ethnic and low-income mothers is even insufficient. Therefore, given the original TPB constructs, our goal was to examine the role of extra theoretical constructs and specific demographic variables, and observe whether the original model would alter., Methods: A cross-sectional analytical study was carried out among 325 pregnant mothers in six purposively selected health care facilities of Kaski and Tanahu districts, using structured pro forma, from December 2018 to November 2019. We developed stepwise multivariate logistic regression from the entered and cleaned data, observed the effects on breastfeeding intention (BFI), and checked against multiple parameters. We interpreted the model with adjusted odds ratios and β coefficients, along with the variance explained., Results and Discussions: Out of 325 pregnant women, more than half (54.8%) were primiparous, and the mean age was 25.1±5 years. All three theoretical constructs of TPB regressed the BFI significantly, with 10.7%, the breastfeeding attitude dominating (β = 0.734, p = .003), and the other two constructs-perceived breastfeeding control (β = 0.659, p = .011) and breastfeeding subjective norm (β = 0.504, p = .045). Interestingly, breastfeeding self-identity added further variance of 5.2% (β = 0.955, p < .001), followed by income, with 3.2% (β = 0.856, p = .001), both of which also tallied large effect sizes. The model parameters showed consistency and robustness. We discuss the variables of the theoretical and extended model for BFI as well as the arguments for the explained variance., Conclusion: Self-identity is a strong and independent predictor of breastfeeding intention and, therefore, should be considered to better prepare for breastfeeding, especially among ethnic pregnant mothers. The direct and intermediate effects of self-concept and income need further study with more robust designs., Competing Interests: CA and RD are faculty members under SHAS. This does not alter our adherence to PLOS ONE policies on sharing data and materials., (Copyright: © 2024 Adhikari et al.

- Abstract
Background: Consumers are increasingly interested in environmentally sustainable dietary patterns. However, specific signals (e.g., language, labels, logos, or packaging) American consumers use to identify environmentally sustainable products are yet to be explored., Objectives: To determine perception and preferences for environmentally sustainable food and associated health and demographic factors associated with consumers' use of signals for environmentally sustainable food products in a nationally representative survey of United States consumers., Methods: Repeated cross-sectional data were collected for the 2019 and 2020 annual online Food and Health Survey by the International Food Information Council. Three questions were analyzed: 1) the stated importance of environmentally sustainable food products, 2) signals consumers use to identify environmentally sustainable food/beverage products, and 3) the impact of environmental sustainability on food/beverage purchase decisions. Questions 2 and 3 were asked only from participants who stated environmental sustainability is important in question 1. Options provided for signals for environmentally sustainable products were recyclable packaging, minimal packaging, labeled organic, labeled locally grown, labeled sustainably sourced, and labeled non-genetically modified organisms (GMOs)/not bioengineered. Poisson regression and logistic regressions were performed to assess associations., Results: Of 1905 completers, 1059 (55.6%) answered that it was somewhat or very important that food products purchased/consumed were environmentally sustainable. Of those, 94% used ≥1 of the 6 signals to determine environmental sustainability when shopping. Some signals were selected despite little association with environmental sustainability (e.g., locally grown and non-GMO/not bioengineered). The number of signals consumers used was associated with education, race/ethnicity, health status, and the level of impact they reported that sustainability plays in their decisions. Associations between consumer characteristics and the use of different signals for environmental sustainability were heterogeneous., Conclusions: Even among consumers who value environmental sustainability in food products, specific signals used by different respondents varied across demographics and health characteristics., (Copyright © 2024 American Society for Nutrition.

- Abstract
Purpose: Parkinson's disease creates an inability to perform previous learned autonomic tasks, such as walking, which worsens with disease progression. Recommendations to incorporate exercise at moderate to high intensities for this population has been established but there is limited knowledge about its impact on clinical based outcomes. The purpose of this research is to investigate the effectiveness of a 6-week intensity-driven walking program on clinical-based outcomes in individuals with PD., Materials/methods: Five individuals with PD were recruited for this single-subject withdrawal design (A-B-A-B) study. 6-minute walk performance and other core neurological measures of gait were collected. Intervention phases incorporated a 30-minute individualized intensity-driven treadmill walking program practiced at 65% or more of ones maximum heart rate. Increased treadmill speed, incline, and resistance were manipulated to reach the target heart rate zone., Results: 6-minute walk test within condition visual analysis demonstrated a therapeutic change during intervention phases and a countertherapeutic change during withdraw periods for all 5 individuals. An abrupt therapeutic effect was demonstrated for all individuals between conditions with the percent of nonoverlapping data ranging from 70-90%. Band method analysis revealed a range of 9-19 sessions two standard deviations above baseline mean performances for all individuals., Conclusion: To achieve sufficient walking performance, gait practiced at higher intensity levels may provide the optimal solution as an adjunct to standard care for individuals with PD who want to improve their walking.

- Abstract
Abstract: Currently, the healthcare workplace is one of the most dangerous in the United States. Over a 3-month period in 2022, two nurses were assaulted every hour. Artificial intelligence (AI) has the potential to prevent workplace violence by developing unique patient insights through accessing almost instantly a patient's medical history, past institutional encounters, and possibly even their social media posts. De-escalating dialog can then be formulated, and hot-button topics avoided. AIs can also monitor patients in waiting areas for potential confrontational behavior.Many have concerns implementing AIs in healthcare. AIs are not expected to be 100% accurate, their performance is not compared with a computer but instead measured against humans. However, AIs are outperforming humans in many tasks. They are especially adept at taking standardized examinations, such as Board Exams, the Uniform Bar Exam, and the SAT and Graduate Record Exam. AIs are also performing diagnosis. Initial reports found that newer models have been observed to equal or outperform physicians in diagnostic accuracy and in the conveyance of empathy.In the area of interdiction, AI robots can both navigate and monitor for confrontational and illegal behavior. A human security agent would then be notified to resolve the situation. Our military is fielding autonomous AI robots to counter potential adversaries. For many, this new arms race has grave implications because of the potential of fielding this same security technology in healthcare and other civil settings.The healthcare delivery sector must determine the future roles of AI in relationship to human workers. AIs should only be used to support a human employee. AIs should not be the primary caregiver and a single human should not be monitoring multiple AIs simultaneously. Similar to not being copyrightable, disinformation produced by AIs should not be afforded 'free speech' protections. Any increase in productivity of an AI will equate with a loss of jobs. We need to ask, If all business sectors utilize AIs, will there be enough paid workers for the purchasing of services and products to keep our economy and society a float?, Competing Interests: Competing Interests: Conflicts of Interest: KTK has investments in several AI and robotic companies including Microsoft, Amazon, and Hyundai and was the keynote speaker regarding AI before the Massachusetts Nurses Association.

- Abstract
Background: Digital imaging combined with deep-learning-based computational image analysis is a growing area in medical diagnostics, including parasitology, where a number of automated analytical devices have been developed and are available for use in clinical practice., Methods: The performance of Parasight All-in-One (AIO), a second-generation device, was evaluated by comparing it to a well-accepted research method (mini-FLOTAC) and to another commercially available test (Imagyst). Fifty-nine canine and feline infected fecal specimens were quantitatively analyzed by all three methods. Since some samples were positive for more than one parasite, the dataset consisted of 48 specimens positive for Ancylostoma spp., 13 for Toxocara spp. and 23 for Trichuris spp., Results: The magnitude of Parasight AIO counts correlated well with those of mini-FLOTAC but not with those of Imagyst. Parasight AIO counted approximately 3.5-fold more ova of Ancylostoma spp. and Trichuris spp. and 4.6-fold more ova of Toxocara spp. than the mini-FLOTAC, and counted 27.9-, 17.1- and 10.2-fold more of these same ova than Imagyst, respectively. These differences translated into differences between the test sensitivities at low egg count levels (< 50 eggs/g), with Parasight AIO > mini-FLOTAC > Imagyst. At higher egg counts Parasight AIO and mini-FLOTAC performed with comparable precision (which was significantly higher that than Imagyst), whereas at lower counts (> 30 eggs/g) Parasight was more precise than both mini-FLOTAC and Imagyst, while the latter two methods did not significantly differ from each other., Conclusions: In general, Parasight AIO analyses were both more precise and sensitive than mini-FLOTAC and Imagyst and quantitatively correlated well with mini-FLOTAC. While Parasight AIO produced lower raw counts in eggs-per-gram than mini-FLOTAC, these could be corrected using the data generated from these correlations., (© 2024. The Author(s).)

Rowe L, Dowd SE, Davidson K, Kovarik C, VanAken M, Jarabek A, and Taylor C
- Abstract
Geothermal features, such as hot springs and mud volcanoes, host diverse microbial life, including many extremophile organisms. The physicochemical parameters of the geothermal feature, such as temperature, pH, and heavy metal concentration, can influence the alpha and beta diversity of microbial life in these environments, as can spatiotemporal differences between sites and sampling. In this study, water and sediment samples were collected and analyzed from eight geothermal sites at Yellowstone National Park, including six hot springs, a mud volcano, and an acidic lake within the same week in July 2019, and these geothermal sites varied greatly in their temperature, pH, and chemical composition. All samples were processed and analyzed with the same methodology and taxonomic profiles and alpha and beta diversity metrics determined with 16S rRNA sequencing. These microbial diversity results were then analyzed with respect to pH, temperature, and chemical composition of the geothermal features. Results indicated that predominant microbial species varied greatly depending on the physicochemical composition of the geothermal site, with decreases in pH and increases in dissolved heavy metals in the water corresponding to decreases in alpha diversity, especially in the sediment samples. Similarly, sites with acidic pH values had more similar microbial populations (beta diversity) to one another than to relatively neutral or alkaline pH geothermal sites. This study suggests that pH and/or heavy metal concentration is a more important driver for microbial diversity and population profile than the temperature for these sites and is also the first reported microbial diversity study for multiple geothermal sites in Yellowstone National Park, including the relatively new mud volcano Black Dragon's Caldron, which erupted in 1948., Competing Interests: SD was employed by Molecular Research LP (MR DNA Lab). The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Rowe, Dowd, Davidson, Kovarik, VanAken, Jarabek and Taylor.)

- Abstract
This note describes the development and testing of a novel, programmable reversing flow 1D (R1D) experimental column apparatus designed to investigate reaction, sorption, and transport of solutes in aquifers within dynamic reversing flow zones where waters with different chemistries mix. The motivation for constructing this apparatus was to understand the roles of mixing and reaction on arsenic discharging through a tidally fluctuating riverbank. The apparatus can simulate complex transient flux schedules similar to natural flow regimes The apparatus uses an Arduino microcontroller to control flux magnitude through two peristaltic pumps. Solenoid valves control flow direction from two separate reservoirs. In-line probes continually measure effluent electrical conductance, pH, oxidation-reduction potential, and temperature. To understand how sensitive physical solute transport is to deviations from the real hydrograph of the tidally fluctuating river, two experiments were performed using: (1) a simpler constant magnitude, reversing flux direction schedule (RCF); and (2) a more environmentally relevant variable magnitude, reversing flux direction schedule (RVF). Wherein, flux magnitude was ramped up and down according to a sine wave. Modeled breakthrough curves of chloride yielded nearly identical dispersivities under both flow regimes. For the RVF experiment, Peclet numbers captured the transition between diffusion and dispersion dominated transport in the intertidal interval. Therefore, the apparatus accurately simulated conservative, environmentally relevant mixing under transient, variable flux flow regimes. Accurately generating variable flux reversing flow regimes is important to simulate the interaction between flow velocity and chemical reactions where Brownian diffusion of solutes to solid-phase reaction sites is kinetically limited., (© 2023 The Authors.

Miller V, Sampson MA, Howell D, and Kitzman P
- Abstract
Importance: Coaching is an effective intervention strategy in occupational therapy but there lacks consensus in the literature about terms, definitions, and approaches used which can be barriers to the clinical use of this method., Objective: The purpose of this review is to understand how coaching adults is used as an intervention to support children with disabilities., Methods: Guidelines from foundational scoping review articles and PRISMA-ScR were followed. Studies using adult coaching as an intervention to support children with disabilities were reviewed. A total of 20 articles met inclusion criteria and were included in the review., Findings: The use of coaching terms and definitions vary. There are commonalities with coaching structures, "key ingredients," and use of outcome measures among studies which can provide a starting framework for occupational therapists wanting to use coaching as an intervention in their practice., Conclusions and Relevance: Coaching adults to support children with disabilities is already known to be an effective occupational therapy intervention strategy. Developing structured protocols with clearer and more unified terminology may improve the fidelity of this intervention approach., What This Article Adds: This article presents current practices in adult coaching to support children with disabilities in Occupational Therapy. The authors discuss commonalities across coaching practices for therapists who wish to use coaching protocols in their clinical practice.

- Abstract
Objective: The aim of this study was to examine the effect of an educational intervention on nurses' knowledge defined as understanding, beliefs, and actions to be taken, regarding nurse suicide., Background: Between 2007 and 2018, nurses were 18% more likely to die by suicide than the general public. As a result, an assessment of nurses' knowledge regarding suicide has become an important issue for nursing administration., Methods: A quasi-experiment (N = 225) was conducted. Variables of interest were assessed pre and post an educational intervention on 3 domains related to suicide., Results: Significant and meaningful differences were found regarding 2 domains of interest in nurses' understanding related to nurse suicide, and actions to be taken, pre and post intervention. A significant change occurred regarding beliefs; however, the difference was small and therefore not meaningful., Conclusions: Finding demonstrate that educational interventions focused on issues related to suicide can enhance nurses' knowledge of the challenges implicit when one considers taking one's own life., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
This study found that a breast cancer survivor cohort who were 3-4 years post-treatment returned to near baseline activity levels, and their important activity categories were nearly evenly distributed among instrumental activities of daily living, high-demand leisure, and social participation. When describing their experiences, three themes emerged: exercise is important physically and emotionally, participating in important activities feels good, and plans have been made to continue engaging in important activities. Further research is needed to compare activity resumption among those receiving or not receiving occupational therapy-at different timepoints-to understand when occupational therapy can make the greatest impact.

Jung H, Kim KJ, and Shin I
- Abstract
Existing research has tended to overlook the diverse roles of union leadership in contributing to member attitudes. Drawing on the social information processing theory, this study examines how union leaders' (shop stewards) service-oriented leadership relates to member job satisfaction. To clarify the mechanism underlying this relationship, this study focuses on union instrumentality as a mediator. The research also examines managers' ethical leadership as a conditional factor in the relationship between union leaders' service-oriented leadership and member job satisfaction through union instrumentality. To test our hypothesis, this study analyzed the results of a survey of 603 respondents from two branches of the Korean Metal Workers' Union. The findings of this study indicate that union instrumentality is the link between service-oriented union leadership and member job satisfaction. Additionally, the strength of the mediated relationship between the aforementioned factors through union instrumentality is contingent on managerial ethical leadership. This study contributes to an integrated understanding of the way in which service-oriented union stewards and ethical managers influence member job satisfaction through their leadership.

- Abstract
The incidence of long COVID in adult survivors of an acute SARS-CoV-2 infection is approximately 11%. Of those afflicted, 26% have difficulty with day-to-day activities. The majority of long COIVD cases occur after mild or asymptomatic acute infection. Children can spread SARS-CoV-2 infections and can also develop long-term neurological, endocrine (type I diabetes), and immunological sequelae. Immunological hypofunction is exemplified by the recent large outbreaks of respiratory syncytial virus and streptococcal infections. Neurological manifestations are associated with anatomical brain damage demonstrated on brain scans and autopsy studies. The prefrontal cortex is particularly susceptible. Common symptoms include brain fog, memory loss, executive dysfunction, and personality changes. The impact on society has been profound. Fewer than half of previously employed adults who develop long COVID are working full-time, and 42% of patients reported food insecurity and 20% reported difficulties paying rent. Vaccination not only helps prevent severe COVID-19, but numerous studies have found beneficial effects in preventing and mitigating long COVID. There is also evidence that vaccination after an acute infection can lessen the symptoms of long COVID. Physical and occupational therapy can also help patients regain function, but the approach must be "low and slow." Too much physical or mental activity can result in post-exertional malaise and set back the recovery process by days or weeks. The complexity of long COVID presentations coupled with rampant organized disinformation, have caused significant segments of the public to ignore sound public health advice. Further research is needed regarding treatment and effective public communication., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
The cellular junctional architecture remodeling by Listeria adhesion protein-heat shock protein 60 (LAP-Hsp60) interaction for Listeria monocytogenes ( Lm ) passage through the epithelial barrier is incompletely understood. Here, using the gerbil model, permissive to internalin (Inl) A/B-mediated pathways like in humans, we demonstrate that Lm crosses the intestinal villi at 48 h post-infection. In contrast, the single isogenic ( lap
- or Δ inlA ) or double ( lap- Δ inlA ) mutant strains show significant defects. LAP promotes Lm translocation via endocytosis of cell-cell junctional complex in enterocytes that do not display luminal E-cadherin. In comparison, InlA facilitates Lm translocation at cells displaying apical E-cadherin during cell extrusion and mucus expulsion from goblet cells. LAP hijacks caveolar endocytosis to traffic integral junctional proteins to the early and recycling endosomes. Pharmacological inhibition in a cell line and genetic knockout of caveolin-1 in mice prevents LAP-induced intestinal permeability, junctional endocytosis, and Lm translocation. Furthermore, LAP-Hsp60-dependent tight junction remodeling is also necessary for InlA access to E-cadherin for Lm intestinal barrier crossing in InlA-permissive hosts., Importance: Listeria monocytogenes ( Lm ) is a foodborne pathogen with high mortality (20%-30%) and hospitalization rates (94%), particularly affecting vulnerable groups such as pregnant women, fetuses, newborns, seniors, and immunocompromised individuals. Invasive listeriosis involves Lm 's internalin (InlA) protein binding to E-cadherin to breach the intestinal barrier. However, non-functional InlA variants have been identified in Lm isolates, suggesting InlA-independent pathways for translocation. Our study reveals that Listeria adhesion protein (LAP) and InlA cooperatively assist Lm entry into the gut lamina propria in a gerbil model, mimicking human listeriosis in early infection stages. LAP triggers caveolin-1-mediated endocytosis of critical junctional proteins, transporting them to early and recycling endosomes, facilitating Lm passage through enterocytes. Furthermore, LAP-Hsp60-mediated junctional protein endocytosis precedes InlA's interaction with basolateral E-cadherin, emphasizing LAP and InlA's cooperation in enhancing Lm intestinal translocation. This understanding is vital in combating the severe consequences of Lm infection, including sepsis, meningitis, encephalitis, and brain abscess., Competing Interests: A patent on LAP use as a tight junction modulator has been issued.- Published

- Abstract
While it is well understood that the content included in an apology matters, what constitutes an effective apology may differ depending on the gender of the person delivering it. In this article, we test competing theoretical perspectives (i.e., role congruity theory and expectancy violation theory [EVT]) about the relative effectiveness of apologies that include language that conforms (or not) with the gender stereotypes ascribed to the apologizer. Results of four studies supported an EVT perspective and showed that apologies were perceived to be relatively more effective when they contradicted gender stereotypes (i.e., communal [agentic] apologies by men [women]). Specifically, Study 1 provided an initial test of the competing hypotheses using celebrity apologies on Twitter. Then, results of three experiments (Studies 2, 3a, and 3b) built upon these initial findings and tested the psychological mechanisms proposed by EVT to explain why counterstereotypical apologies are beneficial (i.e., attributions of interpersonal sensitivity [assertiveness] and enhanced perceptions of benevolence [competence] for men [women]). Our contributions to theory and practice are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

- Abstract
Background: The participation and success of university health students in rural areas is critical in addressing the maldistribution of the rural health workforces internationally. Particular attention to the experiences of mature-aged health students is needed to build a sustainable rural health workforce, given the higher proportions of mature-aged university students in rural, regional and remote areas compared with metropolitan areas and rural mature-aged students wanting to stay in their communities. However, little is known about the kinds of supports rural mature-aged students require to succeed with their studies., Methods: Drawing on rural standpoint theory and using structural inequality as a retention lens, we explored the current and potential supports that rural mature-aged nursing and allied health students require to successfully participate and complete their pre-professional university course. A Stakian multicase study was undertaken with cases at three rural university campuses in Australia. The data collection was primarily qualitative, with semi-structured interviews, campus surveys and focus groups involving 36 participants (including students, academic and professional staff, and placement supervisors)., Results: This study found supports were provided formally and informally by the university, by the community and manifested by students. Several support gaps as well as potential supports to alleviate them were identified. These include formally acknowledging the mature-aged cohort and their diverse experiences and non-university commitments; fostering connections between mature-aged students; making university affordable; preparing mature-aged students for university; adapting course content and delivery; and restructuring placements for mature-aged students., Conclusions: We argue that rural mature-aged nursing and allied health students require supports that are age-specific, appropriate to the community context, and harness existing relational processes of rural university campus activity. Rural university campuses need to involve rural mature-aged students and other stakeholders relevant to each context in the process of identifying and implementing student supports for this cohort., (© 2024.

Rowe L
- Abstract
This article compares the learning outcomes and student perceptions of a one semester undergraduate biochemistry laboratory course that was taught using either a fully online or a fully in-person teaching modality. The semester long biochemistry laboratory mimicked the work sequence a researcher would encounter when transforming a plasmid containing a gene for a recombinant protein (superfolder green fluorescent protein, sf-GFP) and then purifying, identifying, and characterizing that protein. The two modalities of the course were completed in the same semester, by the same instructor, in which students self-selected into which modality they preferred at the beginning of the semester. Students in the in-person section reported enjoying the laboratory course more than the online cohort of students and found it to be less time-consuming. Additionally, a survey of biochemistry laboratory instructors from across the United States, who had experience teaching both online and in-person biochemistry laboratories, indicated that the majority of instructors that responded to the survey preferred the in-person modality: believing them to be more effective and engaging for the students, more enjoyable, and less time-consuming for the instructor. Statistical analysis of formative and summative assessments indicated no significant difference in non-hands-on student learning objective and learning goal scores between the two groups, but the small number of students and instructors in this study limits the generalizability of these results., Competing Interests: The author declares no competing financial interest., (© 2024 The Author.

- Abstract
Objective: The Minnesota Multiphasic Personality Inventory (MMPI) instruments have a long history with respect to the assessment of psychopathic personality traits. The most recent version, the MMPI-3, should be in a good position to continue this tradition, and the aim of the current research was to evaluate its scales for this purpose. We examined, on the basis of previous research, how well conceptually relevant MMPI-3 scales mapped onto dominant contemporary psychopathy models: the traditional three-factor model and triarchic psychopathy model., Hypotheses: We hypothesized that MMPI-3 markers of internalizing would be negatively correlated with boldness, whereas broad and specific markers of externalizing proclivities would be associated with disinhibition and antisociality. We also hypothesized that egocentricity and callousness would be associated with MMPI-3 scales measuring various features of externalizing, interpersonal aggression/antagonism, and grandiosity., Method: We used archival samples of male prison inmates (n = 452), community members with externalizing proclivities (n = 205), and university students (n = 645). These participants completed the Expanded Levenson Self-Report Psychopathy Scale and the Triarchic Psychopathy Measure., Results: Zero-order correlation analyses indicated support for many of our hypotheses across samples, with notable exceptions. Regression and dominance analyses yielded information about the most potent MMPI-3 predictors of each psychopathy domain, with consistency across the three samples. Boldness was associated with low scores on Emotional/Internalizing Dysfunction, Low Positive Emotions, Shyness, and Negative Emotionality/Neuroticism and high scores on Self-Importance and Dominance. For meanness and disinhibition, we found substantial overlap with MMPI-3 scales (e.g., Behavioral/Externalizing Dysfunction, Antisocial Behavior). Meanness was indicated by high Aggression, Cynicism, Aggressiveness, and Disaffiliativeness; disinhibition/antisociality was primarily marked by high Antisocial Behavior, Hypomanic Activation, Impulsivity, and Disconstraint; and Anger Proneness, Aggression, and Cynicism were secondary indicators., Conclusions: These findings provide support for using the MMPI-3 in clinical assessments to corroborate other sources of information regarding psychopathy as well as generate hypotheses for further consideration.

- Abstract
Emergency medical services (EMS) has existed in its modern form for over 50 years. EMS has become a critical public safety net and access point to the larger health care system. Mature EMS systems are in place in most urban areas. However, EMS systems are not as developed in wilderness areas. A barrier to further development of these systems is the lack of an agreed-upon standard of minimum competence and validation of specialized practice. A practice analysis was completed to create such standards. The practice analysis was completed using a multi-step process. A group of subject matter experts constructed a survey of tasks and knowledge needed for wilderness EMS (WEMS) specialty practice. The tasks and knowledge were validated through an industry survey. A total of 947 surveys were submitted for analysis. Of these, 196 were at least 55% complete and used for analysis. North America was heavily represented as a primary practice location with 177 (90.3%) responses out of the 196 total. Of these 177 responses, 164 (92.7%) were from the United States and 12 (6.8%) were from Canada. One hundred seven of the 116 tasks identified by the subject matter expert group were passed by the survey group, and 164 of the 175 knowledge statements were passed by the survey group. An index of agreement (IOA) was calculated and found to be greater than 0.9 for each task and knowledge statement across all subgroups. A content coverage rating was also calculated and the results indicate survey participants felt the content was "adequate" to "well" covered. The survey results were used to construct a pilot examination. Beta testing of the pilot examination was performed. The beta test results were analyzed and a cut score was determined using the Angoff method with a Beuk compromise. The final product of this process is a defensible exam that will certify candidates' cognitive knowledge of the specialty of WEMS. Completion of this practice analysis solidifies WEMS as distinct subspecialty of out-of-hospital medicine. Additionally, it establishes a consensus definition of wilderness paramedicine and standards that may be used by WEMS systems and regulatory entities.

- Abstract
Chronic disease prevention, health, and wellness have become primary practice areas for occupational therapy. Occupational therapists (OTs) in pain rehabilitation are established as essential members of comprehensive and multidisciplinary pain management teams, focusing on increasing occupational performance through participation. This study's purpose was to investigate OTs' experiences managing chronic pain and to explore OTs' effectiveness in supporting clients' wellness and occupational performance through interventions. Eleven OTs ( n = 11) participated with three themes emerging on chronic pain, interventions, and holistic teams. Findings suggest that OTs are successful at treating chronic pain, supporting wellness and occupational performance when their interventions are health-promoting, and clients are enabled to take an active role in their chronic pain management. This study demonstrates the critical impact OTs can have in multidisciplinary teams on clients' outcomes, such as increased occupational performance, wellness, and quality of life (QOL) through engagement in meaningful occupations., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objective: Pt-Mal-LHRH is a newly synthesized chemotherapeutic agent that was designed to selectively target the luteinizing hormone-releasing hormone (LHRH) receptor expressed by triple negative breast cancer (TNBC). The aim of this study was to evaluate the therapeutic dosing, tumor reduction efficacy, and selective distribution of Pt-Mal-LHRH in-vivo., Methods and Results: LHRH tissue expression levels in-vivo were investigated using western blotting and LHRH was found to be increased in reproductive tissues (mammary, ovary, uterus). Further, Pt-Mal-LHRH was found to have increased TNBC tumor tissue platinum accumulation compared to carboplatin by inductively coupled plasma mass spectrometry analysis. The platinum family, compound carboplatin, was selected for comparison due to its similar chemical structure and molar equivalent doses were evaluated. Moreover, in-vivo distribution data indicated selective targeting of Pt-Mal-LHRH by enhanced reproductive tissue accumulation compared to carboplatin. Further, TNBC tumor growth was found to be significantly attenuated by Pt-Mal-LHRH compared to carboplatin in both the 4T1 and MDA-MB-231 tumor models. There was a significant reduction in tumor volume in the 4T1 tumor across Pt-Mal-LHRH doses (2.5-20 mg/kg/wk) and in the MDA-MB-231 tumor at the dose of 10 mg/kg/wk in models conducted by an independent contract testing laboratory., Conclusion: Our data indicates Pt-Mal-LHRH is a targeting chemotherapeutic agent towards the LHRH receptor and reduces TNBC tumor growth in-vivo. This study supports drug conjugation design models using the LHRH hormone for chemotherapeutic delivery as Pt-Mal-LHRH was found to be a more selective and efficacious than carboplatin. Further examination of Pt-Mal-LHRH is warranted for its clinical use in TNBCs, along with, other reproductive cancers overexpressing the LHRH receptor., Competing Interests: the authors have declared that no competing interests exist., (Copyright: © 2023 Ndinguri et al.

- Abstract
Farmers experience psychological distress and suicide at consistently higher rates than workers in other industries. A gatekeeper is an individual who has been trained to recognize warning symptoms of possible suicidal ideations in others. Gatekeeper programs are recognized by the federal Substance Abuse and Mental Health Services Administration as a best practice for suicide prevention. While gatekeeper programs offer promise to addressing the increasing worldwide suicide rate, how to develop these networks in communities with largely ingrained stigma and taboo related to mental health and suicide remains unanswered. Three of this study's researchers were part of the development and pilot of an agricultural community gatekeeper program and questioned how gatekeeper instructor psychological comfort could be conceptualized and operationalized for the purpose of informing gatekeeper instructor recruitment and training. After a thorough review of the literature, the researchers constructed a conceptual developmental model of gatekeeper instructor comfort and created a Gatekeeper Instructor Comfort Measure instrument which was then piloted with Kentucky K-12 and university agricultural educators. The researchers of this study employed the Rasch model to determine whether the developmental model of gatekeeper instructor comfort held together empirically. Infit and outfit mean squares (0.73 to 1.33) indicate that the items measure one construct, or are unidimensional, while person reliability and separation statistics indicate that the Gatekeeper Instructor Comfort Measure is composed of enough items to differentiate respondents into almost four strata of gatekeeper comfort. The Gatekeeper Instructor Comfort Measure's fit to the Rasch model indicates that the instrument meets the requirements of invariant measurement and should serve as a useful measure for other researchers. The instrument's item difficulty hierarchy also serves as a guide for those training gatekeepers on how to target different gatekeeper outcomes sequentially or developmentally. Researchers recommend restructuring item responses to enable greater discrimination between categories and then piloting the instrument again with a more diverse sample. The revised measure could be used pre- and post-gatekeeper instructor training to determine the impact of training on gatekeeper comfort.
