Space Force Design Project

The objective of our research project is to develop a lab testbed composed of a curved surface to represent a spacecraft hull, a mobile robot equipped with repair tools, and a robotic arm equipped with a laser 3D scanner. This project is part of a larger grant to the University of Akron from Space Force and Air Research Labs. The lab testbed developed in this project will be used to assist in creating and testing a software and algorithm to inspect and repair spacecraft while in orbit. The project will involve researching spacecraft hulls to create an accurate simulation bed, using the gathered information to design a testbed complete with all components found on the outside of a spacecraft, researching and designing a mobile robot to traverse the hull surface, and implementing the use of the 3D scanner by creating a gripper to allow the robotic arm to use the scanner

Diagnostic tools in Rhinology EAACI position paper

This EAACI Task Force document aims at providing the readers with a comprehensive and complete overview of the currently available tools for diagnosis of nasal and sino-nasal disease. We have tried to logically order the different important issues related to history taking, clinical examination and additional investigative tools for evaluation of the severity of sinonasal disease into a consensus document. A panel of European experts in the field of Rhinology has contributed to this consensus document on Diagnostic Tools in Rhinology

Transiting Exoplanet Survey Satellite

The Transiting Exoplanet Survey Satellite (TESS) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission. The spacecraft will be placed into a highly elliptical 13.7-day orbit around the Earth. During its 2-year mission, TESS will employ four wide-field optical charge-coupled device cameras to monitor at least 200,000 main-sequence dwarf stars with IC≈4−13IC≈4−13 for temporary drops in brightness caused by planetary transits. Each star will be observed for an interval ranging from 1 month to 1 year, depending mainly on the star’s ecliptic latitude. The longest observing intervals will be for stars near the ecliptic poles, which are the optimal locations for follow-up observations with the James Webb Space Telescope. Brightness measurements of preselected target stars will be recorded every 2 min, and full frame images will be recorded every 30 min. TESS stars will be 10 to 100 times brighter than those surveyed by the pioneering Kepler mission. This will make TESS planets easier to characterize with follow-up observations. TESS is expected to find more than a thousand planets smaller than Neptune, including dozens that are comparable in size to the Earth. Public data releases will occur every 4 months, inviting immediate community-wide efforts to study the new planets. The TESS legacy will be a catalog of the nearest and brightest stars hosting transiting planets, which will endure as highly favorable targets for detailed investigations.Astronom

TESS Discovery of an Ultra-short-period Planet around the Nearby M Dwarf LHS 3844

Data from the newly commissioned Transiting Exoplanet Survey Satellite has revealed a 'hot Earth' around LHS 3844, an M dwarf located 15 pc away. The planet has a radius of R ⊕ and orbits the star every 11 hr. Although the existence of an atmosphere around such a strongly irradiated planet is questionable, the star is bright enough (I = 11.9, K = 9.1) for this possibility to be investigated with transit and occultation spectroscopy. The star's brightness and the planet's short period will also facilitate the measurement of the planet's mass through Doppler spectroscopy

Sexuality Related Social Support Among Same-Sex Attracted Youth

Supportive relationships with parents and peers are thought to be important in helping gay, lesbian, bisexual, or questioning youth cope with stressors related to their sexual identity. However, studies of same-sex attracted youth have yielded only minimal evidence for the link between social support and mental health. The lack of empirical findings may relate to inadequate measurement of the types of social support most relevant for same-sex attracted youth. Using matching theory as a theoretical framework, the present study examined same-sex attracted youth's perceptions of support for coping with problems specifically related to their sexuality. Ninety-eight same-sex attracted young people ages 18-21 were asked about support from family members, heterosexual friends, and sexual minority friends for dealing with problems related to, and not related to, their sexuality. Sexuality related life stressors, substance use severity, and symptoms of emotional distress were also assessed. A within-subject factorial ANOVA revealed differences between sexuality related support and non-sexuality related support across the three relationship types. From family members and heterosexual peers, participants perceived sexuality related support as less available than support for problems not related to sexuality. Non-heterosexual peers provided the highest levels of sexuality related support, and were seen as equally supportive across sexuality related and non-sexuality related domains. Linear regression analyses examined the roles of sexuality related and non-sexuality related support in predicting two mental health outcomes: emotional distress and substance use severity. Contrary to expectations, main effects for sexuality related support and non-sexuality related support did not predict emotional distress. Tests of "buffering" models revealed participants' overall perceptions of sexuality related support moderated the relationship between sexuality stress and psychological distress, such that higher levels of sexuality related support may have been protective. Perceptions of non-sexuality related support, on the other hand, did not moderate links between sexuality stress and emotional distress. Neither main effect nor buffering models were significant in predicting substance use severity. Results of this study provide important information about the types of social support most relevant to same-sex attracted youth.</p

Searching For Outcomes Of Leadership: A 25-Year Review

A significant question in management research is, What criteria should be used to evaluate the effects of leadership? In this review, the authors systematically summarize various ways the field of leadership has (and has not) sought to answer questions about whether, when, and how leadership affects outcomes. A total of 1,161 empirical studies over 25 years, spanning micro- and macro-oriented perspectives, were content coded to answer six basic questions that set the scope of leadership science. The authors first descriptively summarize these criterion issues in the empirical literature and draw comparisons across areas (e.g., To what extent have leader-member exchange, transformational, and strategic leadership research differentially examined various outcomes?). Second, the authors explore the implications of criterion selection issues for the further advancement of leadership theory and offer concrete recommendations for future leadership research. © The Author(s) 2011

The Relationship Between Personality, Recalled Cybersickness Severity, and Recalled Cybersickness Recovery Time

This is a manuscript of a proceeding published as Jasper, Angelica, Taylor Doty, Nathan Sepich, Michael C. Dorneich, Stephen B. Gilbert, and Jonathan W. Kelly. "The Relationship Between Personality, Recalled Cybersickness Severity, and Recalled Cybersickness Recovery Time." In Proceedings of the Human Factors and Ergonomics Society Annual Meeting, vol. 65, no. 1, pp. 206-210. Sage CA: Los Angeles, CA: SAGE Publications, 2021.

Posted with permission.Characteristics of a virtual reality user are known to affect cybersickness, but the specific role of individual differences, such as personality, is largely unknown. This study addressed this gap through examination of subjective recall survey data relating to experiences in virtual reality, including severity of cybersickness symptoms, cybersickness recovery time, and personality. Mediational structural equation modeling on data from 203 participants who used virtual reality at least once per month indicated that extraversion, agreeableness, and conscientiousness were associated with cybersickness severity and that severity was associated with cybersickness recovery time. Further, cybersickness severity fully mediated the relationship between personality and recovery time. These findings highlight the potential relationship between individual differences in personality and suggest further investigation into cybersickness with experimental data and validated measures

Leadership Across Levels: Levels Of Leaders And Their Levels Of Impact

This article assesses 25. years of empirical leadership research in 11 top journals with the goal of understanding current practice and future needs for drawing solid conclusions about leadership at different hierarchical levels of the organization, as well as leadership\u27s effects on individuals, teams, units and organizations. We summarize the hierarchical level of leader and outcome level of analysis studied in different theoretical perspectives on leadership (traits, behavioral, transformational, LMX, strategic, shared) and by journal outlet. Among our findings, we observe that significantly less attention has been devoted to team- and unit-level emergent processes and outcomes, despite its conceptual relevance for leadership theory and practice. Four critical opportunities for advancing leadership science are presented. © 2010 Elsevier Inc
