Health & Wellness Team- Esports at CSUDH

The goal of the Health and Wellness Team within Esports at California State University, Dominguez Hills (CSUDH) is to share the skill sets we have learned in our professional careers and apply them to our student eAthletes, so they are equipped with the mental, physical, nutritional, and socio-emotional resources, education, and support they need to thrive. PURPOSE: The Health and Wellness Team (HWT) within Esports at CSUDH and the student club organization aligns with the five pillars of the academy: Academics & Research, Career Development, Community, Competition, and Entertainment. The HWT can reach our student population through mental, physical, nutritional, and socio-emotional education. Our goal is to share the skill sets within Psychology and Kinesiology; and apply them to Esports at CSUDH to provide our students with the optimal care and support they need to flourish both mentally and physically as they each balance life as student eAthletes. The HWT also emphasizes the importance of nurturing an individual’s character strengths, values, interests, and abilities. METHODS: Within the past 3 years we have implemented these practices through workshops, seminars, online talk-sessions, social media post, and videos to educate and promote self-care. A timeline of events and important key points from each session will be highlighted during this presentation. Our future goals are to conduct evaluations of the program and track the progress of our student eAthletes with specific quantitative and qualitative methods that will allow us to identify protective factors and recommendations to increase overall wellness. RESULTS: Through our current work, we have become conscious to the effects that inadequate self-care, coping skills, and health education can have on student eAthletes. When student eAthletes are not provided with the necessary skill sets, resources, and insights needed, it makes it difficult for them to flourish mentally, emotionally, physically, academically, and competitively. CONCLUSION: The current presentation will review this information and propose a self-care model which will include mindfulness techniques, communication and team-building strategies, ergonomic, physical activity, and fitness strategies, and other creative means

The impact of low energy proton damage on the operational characteristics of EPIC-MOS CCDs

The University of Tübingen 3.5 MeV Van de Graaf accelerator facility was used to investigate the effect of low energy protons on the performance of the European Photon Imaging Camera (EPIC), metal–oxide semiconductor (MOS), charge coupled devices (CCDs). Two CCDs were irradiated in different parts of their detecting areas using different proton spectra and dose rates. Iron-55 was the calibration source in all cases and was used to measure any increases in charge transfer inefficiency (CTI) and spectral resolution of the CCDs. Additional changes in the CCD bright pixel table and changes in the low X-ray energy response of the device were examined. The Monte Carlo code Stopping Range of Ions in Matter (SRIM) was used to model the effect of a 10 MeV equivalent fluence of protons interacting with the CCD. Since the non-ionising energy loss (NIEL) function could not be applied effectively at such low proton energies. From the 10 MeV values, the expected CTI degradation could be calculated and then compared to the measured CTI changes

Confinement Effects on Carbon Dioxide Methanation: A Novel Mechanism for Abiotic Methane Formation

An important scientific debate focuses on the possibility of abiotic synthesis of hydrocarbons during oceanic crust-seawater interactions. While on-site measurements near hydrothermal vents support this possibility, laboratory studies have provided data that are in some cases contradictory. At conditions relevant for sub-surface environments it has been shown that classic thermodynamics favour the production of CO2 from CH4, while abiotic methane synthesis would require the opposite. However, confinement effects are known to alter reaction equilibria. This report shows that indeed thermodynamic equilibrium can be shifted towards methane production, suggesting that thermal hydrocarbon synthesis near hydrothermal vents and deeper in the magma-hydrothermal system is possible. We report reactive ensemble Monte Carlo simulations for the CO2 methanation reaction. We compare the predicted equilibrium composition in the bulk gaseous phase to that expected in the presence of confinement. In the bulk phase we obtain excellent agreement with classic thermodynamic expectations. When the reactants can exchange between bulk and a confined phase our results show strong dependency of the reaction equilibrium conversions, [Formula: see text], on nanopore size, nanopore chemistry, and nanopore morphology. Some physical conditions that could shift significantly the equilibrium composition of the reactive system with respect to bulk observations are discussed

Islands of conformational stability for Filopodia

Filopodia are long, thin protrusions formed when bundles of fibers grow outwardly from a cell surface while remaining closed in a membrane tube. We study the subtle issue of the mechanical stability of such filopodia and how this depends on the deformation of the membrane that arises when the fiber bundle adopts a helical configuration. We calculate the ground state conformation of such filopodia, taking into account the steric interaction between the membrane and the enclosed semiflexible fiber bundle. For typical filopodia we find that a minimum number of fibers is required for filopodium stability. Our calculation elucidates how experimentally observed filopodia can obviate the classical Euler buckling condition and remain stable up to several tens of . We briefly discuss how experimental observation of the results obtained in this work for the helical-like deformations of enclosing membrane tubes in filopodia could possibly be observed in the acrosomal reactions of the sea cucumber Thyone, and the horseshoe crab Limulus. Any realistic future theories for filopodium stability are likely to rely on an accurate treatment of such steric effects, as analysed in this work

Neutrophil gelatinase-associated lipocalin: its response to hypoxia and association with acute mountain sickness.

Acute Mountain Sickness (AMS) is a common clinical challenge at high altitude (HA). A point-of-care biochemical marker for AMS could have widespread utility. Neutrophil gelatinase-associated lipocalin (NGAL) rises in response to renal injury, inflammation and oxidative stress. We investigated whether NGAL rises with HA and if this rise was related to AMS, hypoxia or exercise. NGAL was assayed in a cohort (n = 22) undertaking 6 hours exercise at near sea-level (SL); a cohort (n = 14) during 3 hours of normobaric hypoxia (FiO2 11.6%) and on two trekking expeditions (n = 52) to over 5000 m. NGAL did not change with exercise at SL or following normobaric hypoxia. During the trekking expeditions NGAL levels (ng/ml, mean ± sd, range) rose significantly (P < 0.001) from 68 ± 14 (60-102) at 1300 m to 183 ± 107 (65-519); 143 ± 66 (60-315) and 150 ± 71 (60-357) at 3400 m, 4270 m and 5150 m respectively. At 5150 m there was a significant difference in NGAL between those with severe AMS (n = 7), mild AMS (n = 16) or no AMS (n = 23): 201 ± 34 versus 171 ± 19 versus 124 ± 12 respectively (P = 0.009 for severe versus no AMS; P = 0.026 for mild versus no AMS). In summary, NGAL rises in response to prolonged hypobaric hypoxia and demonstrates a relationship to the presence and severity of AMS

First evidence of industrial fly-ash in an Antarctic ice core

Spheroidal carbonaceous particles (SCPs) are a component of fly-ash, the particulate by-product of industrial high temperature combustion of fuel-oil and coal-series fuels. We provide the first evidence that these indelible markers of industrialisation have been deposited in Antarctic ice, thousands of kilometres from any potential source. The earliest observed particle was deposited in an ice layer from 1936 CE. While depositional fluxes are low, chemical analysis of individual SCPs indicates a coal combustion origin

Strategies to Reduce Absenteeism in the Public Sector Workplace

When unplanned absences occur, employers incur lost productivity and additional costs. In the United States, missed work because of employee absence costs organizations about $202 billion dollars annually. Grounded in Burn’s transformational leadership theory, the purpose of this qualitative single case study was to explore effective strategies public works department leaders use to reduce absenteeism in the workplace. The participants included 9 leaders who worked in a chosen department in the local government who successfully reduced absenteeism in the workplace. The data collection process included conducting semistructured interviews and reviewing organizational documents. The data were analyzed using a thematic analysis process, and three themes emerged to include collaboration and employee engagement, communication, and organizational culture. A key recommendation is to restructure communications about absenteeism policies while engaging employees in essential aspects of the organization. The implication for positive social change includes the potential to decrease the local government’s related costs from employee absenteeism, thereby increasing resources for supporting social initiatives, individuals, and communities

The Temporal Relationship between Stress and Spasticity, a Comparison between Subjects with and without Intact Thyroid Function

Purpose/Hypothesis: Stress has been studied as a credible trigger of spasticity, but evidence is limited concerning temporal relationships. Case studies of complex regional pain syndrome (CRPS) and fibromyalgia (FM) have established a ten-day delay between psychogenic stress and episodic pain flares. This is explained by a stress induced release of thyroxine (T4) from the thyroid gland via the hypothalamus-pituitary-thyroid (HPT) axis, which reaches its peak effect by day 10. Models suggest that T4 may increase peripheral nerve excitability, which could increase sensitivity in 1A fibers from muscle spindles, leading to hyper-excitability in motor neuron pools. The purpose of our study is to explore the temporal relationship between stress & spasticity, to see if subjects experience latent increases in spasticity due to stress. Subjects: Subjects ranged from 48-84 years old, including one male with CVA history & one female with CVA history s/p thyroidectomy. Materials/Methods: Every day for 12 weeks, participants completed stress and spasticity inventories. Stress was measured with a visual analog stress scale (VASS) and spasticity with a visual analog functional scale (VAFS) assessing the degree of difficulty to execute a standard daily task due to spasticity severity. Quantitative criteria were established defining days of peak stress and days of peak spasticity. Final temporal relationship results between stress and spasticity were analyzed with serial lag correlations for 0-12 day lags. Results: After 12 weeks of data collection, the male manifested a significant correlation to spasticity related function ten days after criterion peak stress days. Serial lag analysis on peak stress days for this person revealed a 70% correlation supporting a 10-day impact on peak spasticity. The female subject revealed one event in spasticity-related function 10 days after peak stress event, which yields an insignificant 10-day lag correlation of 9.1%. This subject, with history of thyroidectomy, reports taking daily administration of levothyroxine. Consequently, her results are not surprising, since her HTP pathway cannot be influenced by stress. Conclusions: Based on results, evidence supports an increase in CVA-related spasticity ten days after high stress episodes. This relationship was not observed in our female subject s/p thyroidectomy, lending inverse support to the hypothesis that latent ten-day effects may be due to the HPT axis. Clinical Relevance: Patients and therapists frequently are at a loss to explain episodic elevations in spasticity severity. If a consistent temporal relationship between stress and spasticity is confirmed, it would give caregivers, patients, and therapists insight into understanding and predicting episodes of decreased function following high stress days

84M5, 84M6, 84M7. Location: Merredin Research Station Merredin, Western Australia. Three experiments were conducted to measure the productivity and water use of alternative wheatbelt crop species on contrasting soil types in a dry mediterranean environment. Crop species investigated were wheat, barley, cereal rye, narrow leafed lupin and field pea. These were grown on three contrasting soil types, a red-brown earth, a sandy loam over clay and a deep loamy sand; all soils occurring within close proximity to each other. Detailed measurements were made of meteorological conditions, dry matter production, leaf area, root growth, soil water profiles, light interception and plant water status. This report gives the background and significance of the study, the methods employed and results obtained

Digital Entrepreneurship in China: Insight into Online Business Start-up Among Chinese University Students Based On Entrepreneurial Intention

This paper investigates the entrepreneurial intention of Chinese university students to provide insight into digital entrepreneurship. An online survey of 305 university students in Beijing was the basis for the data used to test a logistic regression model of the variables underpinning entrepreneurial intention. Factors determining whether Chinese students intend to engage in digital entrepreneurship were “family business”, “perceived motivations” (especially “Self-achievement”), and “perceived barriers” (especially “Lack of experience”). These are a subset of the antecedent factors influencing entrepreneurship more broadly. The nature of digital entrepreneurship may negate some of the factors, especially culture, that serve as barriers to entrepreneurship in the Chinese context. Although this study is limited by its quantitative methodology and focus on Chinese students attending a single university in Beijing, it contributes to knowledge regarding student engagement with digital entrepreneurship
