This book was released on 2018-10-15 with total page 42 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.

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.

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.

This book was released on 2018-07-15 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the theoretical and operational foundations for our analysis of skill in extravehicular mass handling. A review of our research on postural control, human-environment interactions, and exploratory behavior in skill acquisition is used to motivate our analysis. This scientific material is presented within the context of operationally valid issues concerning extravehicular mass handling. We describe the development of meaningful empirical measures that are relevant to a special class of nested control systems: manual interactions between an individual and the substantial environment. These measures are incorporated into a unique empirical protocol implemented on NASA's principal mass handling simulator, the precision air-bearing floor, in order to evaluate skill in extravehicular mass handling. We discuss the components of such skill with reference to the relationship between postural configuration and controllability of an orbital replacement unit, the relationship between orbital replacement unit control and postural stability, the relationship between antecedent and consequent movements of an orbital replacement unit, and the relationship between antecedent and consequent postural movements. Finally, we describe our expectations regarding the operational relevance of the empirical results as it pertains to extravehicular activity tools, training, monitoring, and planning.

Available in PDF, EPUB and Kindle. Book excerpt: Les écosystèmes d'affaires représentent des enjeux à la fois économiques et territoriaux. Plusieurs dimensions les caractérisent : une grande hétérogénéité des acteurs, un destin commun, un standard ou un savoir-faire utilisé par plusieurs entreprises, un ou plusieurs leaders dont le rôle est crucial pour l'écosystème, une vision partagée par les autres membres de l'écosystème d'affaires et des processus de coopétition. À partir d'études de cas, mais aussi de points de vue théoriques structurants, cet ouvrage propose un état des lieux des connaissances actuelles des écosystèmes d'affaires. Il examine plus particulièrement le rôle des PME dans ces coalitions. Comment les différencier des autres formes de réseaux ? Quel cadrage théorique utiliser pour bien appréhender les écosystèmes ? Quelles stratégies mettre en oeuvre ? Comment coordonner l'écosystème ?

Book excerpt: Power is all-encompassing in Russia, and mediates most interactions among people, including everyday decisions. Even the recent administrative reforms in the country, which began at the end of the 1990s, have tried to reshape the government institutions and modernize the country through the use of power. Changes were initiated and implemented by people vested with power. Power, convention, and trust can all support coordination. However, in the Russian institutional context power tends not only to supplement the alternative coordination mechanisms but also to substitute them. Power can be used to solve problems related to social action by merging two (or several) centers of decision-making into one. The actor vested with power decides exactly how coordination and adjustment can be achieved. This path-breaking volume shows how power turns into a unique coordination mechanism and what are consequences of such transformation for everyday life and businesses. Market as a Weapon focuses on issues of power and domination using the configuration of power relationships in Russia as a "critical case," but goes far beyond a narrowly defined scope of country-specific studies. Particular emphasis is put on domination by virtue of a constellation interests in the market, since this is a relatively underexplored yet broadly used technique for imposing will in all countries that heavily rely on interventionist policies. Instead of being a liberating force, the market becomes an additional instrument facilitating the continuous reproduction of power, which explains the title of the book. Both qualitative and quantitative data, including more than one hundred in-depth interviews with experts, state servants, and businesspeople in Russia, as well as statistics, are used throughout the text of this major book.

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.

This book was released on 2005-09-22 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the complexities of the translation process. Informed by theoretical and methodological advances in translation studies, research on writing and the expertise paradigm, it explores translation as a text reproduction task. With triangulation of data from Russian-Swedish translation – think-aloud-methodology and computer logging of the writing process - it makes a cross-sectional comparison of subjects with different amounts of translation experience, highlighting crucial aspects of professional competence and expertise in translation. The book also elaborates a method for a combined product and process analysis, applying it to the study of one type of explicitation: increased cohesive explicitness of the target text. The results have implications for translation theory and pedagogy. This volume will be of interest to translation scholars and translator trainers, irrespective of language combination, as well as to specialists in Russian and Swedish. It will also appeal to researchers on expertise in other domains.
