Book Description
The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Book Description
This book discusses the contested issue of how different kinds of special educational support in Norway, such as placement in special classes or use of teacher assistants, prepare Special Educational Need (SEN) students for further education and adult life. This is done by following former students categorized as having special educational needs for twenty years, from the start of the upper secondary school until their mid-thirties. Different choices and the adjustments and active adaptations young people make throughout their lives is a recurring theme, focusing on education, work, family, mental health, and social networks. The authors in this volume analyze and critically discuss topics around competence attainment in upper secondary school and higher education, employment, public support in adult life, mental health, social exclusion and isolation, and data-mediated networks. It concludes how the experiences from school time have affected the adaptation in later adulthood, and provides an answer to whether the assistive measures have benefits. What are the consequences in the short and long run? A central explanatory tension is between disabled students and disabling schools. We trace consequences – possibly non-intended – for the former SEN students due to the stigmatization effect of receiving special educational help in a vulnerable phase of life. The authors interpret results within a framework of life course approaches and disability theories. The perspectives introduced in the book are of interest for researchers and academics in the social sciences, such as sociology, special education, and social work.

Book Description
The original charter of the Space Science Board was established in June 1958, three months before the National Aeronautics and Space Administration (NASA) opened its doors. The Space Science Board and its successor, the Space Studies Board (SSB), have provided expert external and independent scientific and programmatic advice to NASA on a continuous basis from NASA's inception until the present. The SSB has also provided such advice to other executive branch agencies, including the National Oceanic and Atmospheric Administration (NOAA), the National Science Foundation (NSF), the U.S. Geological Survey (USGS), the Department of Defense, as well as to Congress. Space Studies Board Annual Report 2017 covers a message from the chair of the SSB, David N. Spergel. This report also explains the origins of the Space Science Board, how the Space Studies Board functions today, the SSB's collaboration with other National Academies of Sciences, Engineering, and Medicine units, assures the quality of the SSB reports, acknowledges the audience and sponsors, and expresses the necessity to enhance the outreach and improve dissemination of SSB reports. This report will be relevant to a full range of government audiences in civilian space research - including NASA, NSF, NOAA, USGS, and the Department of Energy, as well members of the SSB, policy makers, and researchers.

Book Description
Discusses planetary protection issues for the Russian Mars '94 mission, as well as for future Mars lander missions including the planned Mars '96 and U.S. MESUR Pathfinder and Network missions. The topics summarized include exobiology science objectives for Mars exploration, current international policy on planetary protection, planetary protection requirements developed for earlier missions, mission plans and designs for future U.S. and Russian Mars landers, biological contamination of spacecraft components, and techniques for spacecraft bioload reduction. In addition, the recent recommendations of the U.S. Space Studies Board (SSB) were also summarized. One additional topic briefly considered was the identification of some issues related to planetary protection considerations for Mars sample return missions.

Book Description
In this comprehensive and interdisciplinary volume, former NASA Chief Historian Steven Dick reflects on the exploration of space, astrobiology and its implications, cosmic evolution, astronomical institutions, discovering and classifying the cosmos, and the philosophy of astronomy. The unifying theme of the book is the connection between cosmos and culture, or what Carl Sagan many years ago called the “cosmic connection.” As both an astronomer and historian of science, Dr. Dick has been both a witness to and a participant in many of the astronomical events of the last half century. This collection of papers presents his reflections over the last forty years in a way accessible to historians, philosophers, and scientists alike. From the search for alien life to ongoing space exploration efforts, readers will find this volume full of engaging topics relevant to science, society, and our collective future on planet Earth and beyond.

Book Description
The second volume of the ultimate reference on the science and applications of aggregation-induced emission The Handbook of Aggregation-Induced Emission explores foundational and advanced topics in aggregation-induced emission, as well as cutting-edge developments in the field, celebrating twenty years of progress and achievement in this important and interdisciplinary field. The three volumes combine to offer readers a comprehensive and insightful interpretation accessible to both new and experienced researchers working on aggregation-induced emission. In Volume 2: Typical AIEgens Design, the editors address the design and synthesis of typical AIEgens that have made significant contributions to aggregation-induced emission research. Recent advances in the development of aggregation-induced emission systems are discussed and the book covers novel aggregation-induced emission systems in small molecule organogels, polymersomes, metal-organic coordination complexes and metal nanoclusters. Readers will also discover: A thorough introduction to the synthesis and applications of tetraphenylpyrazine-based AIEgens, AIEgens based on 9,10-distyrylanthracene , and the Salicylaldehyde Schiff base Practical discussions of aggregation-induced emission from the sixth main group and fluorescence detection of dynamic aggregation processes using AIEgens Coverage of cyclic triimidazole derivatives and the synthesis of multi-phenyl-substituted pyrrole based materials and their applications Perfect for academic researchers working on aggregation-induced emission, this set of volumes is also ideal for professionals and students in the fields of photophysics, photochemistry, materials science, optoelectronic materials, synthetic organic chemistry, macromolecular chemistry, polymer science, and biological sciences.
