This book was released on 2018-07-15 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report we describe the details of our empirical protocol effort investigating skill in extravehicular mass handling using NASA's principal mass handling simulator, the precision air bearing floor. Contents of this report include a description of the necessary modifications to the mass handling simulator; choice of task, and the description of an operationally relevant protocol. Our independent variables are presented in the context of the specific operational issues they were designed to simulate. The explanation of our dependent variables focuses on the specific data processing procedures used to transform data from common laboratory instruments into measures that are relevant to a special class of nested control systems (discussed in Volume 1): manual interactions between an individual and the substantial environment. The data reduction is explained in the context of the theoretical foundation described in Volume 1. Finally as a preface to the presentation of the empirical data in Volume 3 of this report series, a set of detailed hypotheses is presented.

This book was released on 2018-07-15 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key attributes of skilled mass handling were identified through an examination of lessons learned by the extravehicular activity operational community. These qualities were translated into measurable quantities. The operational validity of the ground-based investigation was improved by building a device that increased the degrees of freedom of extravehicular mobility unit motion on the Precision Air-Bearing Floor. The results revealed subtle patterns of interaction between motions of an orbital replacement unit mockup and mass handler that should be important for effective performance on orbit. The investigation also demonstrated that such patterns can be measured with a variety of common instruments and under imperfect conditions of observation. Riccio, Gary E. and McDonald, P.

Download or read book Understanding Skill in Eva Mass Handling Volume 4 An Integrated Methodology for Evaluating Space Suit Mobility and Stability written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-12 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The empirical investigation of extravehicular activity (EVA) mass handling conducted on NASA's Precision Air-Bearing Floor led to a Phase I SBIR from JSC. The purpose of the SBIR was to design an innovative system for evaluating space suit mobility and stability in conditions that simulate EVA on the surface of the Moon or Mars. The approach we used to satisfy the Phase I objectives was based on a structured methodology for the development of human-systems technology. Accordingly the project was broken down into a number of tasks and subtasks. In sequence, the major tasks were: 1) Identify missions and tasks that will involve EVA and resulting mobility requirements in the near and long term; 2) Assess possible methods for evaluating mobility of space suits during field-based EVA tests; 3) Identify requirements for behavioral evaluation by interacting with NASA stakeholders;.4) Identify necessary and sufficient technology for implementation of a mobility evaluation system; and 5) Prioritize and select technology solutions. The work conducted in these tasks is described in this final volume of the series on EVA mass handling. While prior volumes in the series focus on novel data-analytic techniques, this volume addresses technology that is necessary for minimally intrusive data collection and near-real-time data analysis and display.McDonald, P.

Download or read book Assembling and Supplying the ISS written by David J. Shayler and published by Springer. This book was released on 2017-07-20 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The creation and utilization of the International Space Station (ISS) is a milestone in space exploration. But without the Space Shuttle, it would have remained an impossible dream. Assembling and Supplying the ISS is the story of how, between 1998 and 2011, the Shuttle became the platform which enabled the construction and continued operation of the primary scientific research facility in Earth orbit. Fulfilling an objective it had been designed to complete decades before, 37 Shuttle missions carried the majority of the hardware needed to build the ISS and then acted as a ferry and supply train for early resident crews to the station. Building upon the decades of development and experience described in the companion volume Linking the Space Shuttle and Space Stations: Early Docking Technologies from Concept to Implementation, this book explores • a purpose-built hardware processing facility • challenging spacewalking objectives • extensive robotic operations • undocking a unmanned orbiter The experience and expertise gained through these missions allows space planners to improve space construction skills in advance of even more ambitious plans in the future.

Download or read book Understanding Second Language Acquisition written by Lourdes Ortega and published by Routledge. This book was released on 2014-02-04 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether we grow up with one, two, or several languages during our early years of life, many of us will learn a second, foreign, or heritage language in later years. The field of Second language acquisition (SLA, for short) investigates the human capacity to learn additional languages in late childhood, adolescence, or adulthood, after the first language --in the case of monolinguals-- or languages --in the case of bilinguals-- have already been acquired. Understanding Second Language Acquisition offers a wide-encompassing survey of this burgeoning field, its accumulated findings and proposed theories, its developed research paradigms, and its pending questions for the future. The book zooms in and out of universal, individual, and social forces, in each case evaluating the research findings that have been generated across diverse naturalistic and formal contexts for second language acquisition. It assumes no background in SLA and provides helpful chapter-by-chapter summaries and suggestions for further reading. Ideal as a textbook for students of applied linguistics, foreign language education, TESOL, and education, it is also recommended for students of linguistics, developmental psycholinguistics, psychology, and cognitive science.

The programme for the event promises an extensive range of peer-reviewed papers, networking opportunities and presentations from leaders in the field."

Download or read book Legalized Prostitution in Germany written by Annegret Staiger and published by Indiana University Press. This book was released on 2022-02-01 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Germany has been infamously dubbed the "Brothel of Europe," but how does legalized prostitution actually work? Is it empowering or victimizing, realistic or dangerous? In Legalized Prostitution in Germany, Annegret D. Staiger's ethnography engages historical, cultural, and legal contexts to reframe the brothel as a place of longing and belonging, of affective entanglements between unlikely partners, and of new beginnings across borders, while also acknowledging the increasingly exploitative labor practices. By sharing the stories of sex workers, clients, and managers within the larger legal system—meant to provide dignity and safety through regulation—Staiger skillfully frames the economic aspects of commercial sex work and addresses important questions about sexual labor, intimacy, and relationships. Weaving insightful scholarship with beautiful storytelling, Legalized Prostitution in Germany provides readers with a deeper understanding of the complexities of legalized prostitution.
