Languages : en
Pages : 68
Book Description
In 1940, the Census of Housing counted 37 million housing units. 50 years later, the 1990 census counted more than 102 million units, a gain of 173%. This report presents an overview of the trends in American housing during that 50-year period. It examines housing growth, housing demographics, owners and renters, household mobility and housing turnover, race and Hispanic origin, housing types and characteristics, housing quality and amenities, energy consumption, housing prices and costs, ownership and mortgage characteristics, and vacant housing. Photos, tables, figures and diagrams.

Phytoplankton and Trophic Gradients
Author: M. Alvarez-CobelasPublisher: Springer Science & Business Media
ISBN: 940172668X
Category : Science
Languages : en
Pages : 363
Book Description
These proceedings deal with the relationship between species composition of freshwater phytoplankton and the trophic gradient. Particular regard is paid to the composite question, what lives where and why? Overview papers report the state of the art and suggest that the trophic spectrum appears to be a probabilistic outcome of several dimensions of variability that impinge upon phytoplankton species selection. Studies on community structure span all latitudes from those of Antarctica to equatorial Brazil, and also include reports on light and nutrient gradients, pH and fish-stock effects on species composition. Seasonal and longterm phytoplankton dynamics in lakes of varying trophic status are also considered. Finally, studies on the taxonomy and autoecology of some groups (e.g. Volvocales, Chrysophytes and Euglenophytes) living at the extremes of the trophic spectrum contribute to our knowledge of this usually neglected phytoplankton. This is the first time that a book covers such a topic, and it will prove an excellent source of information to anyone working on phytoplankton ecology and ecological indicators. Limnologists in general, algologists and the technical staff at water authorities will all benefit by reading this book.
Nucleation and Crystallization of Glasses and Glass-Ceramics
Author: Wolfram HölandPublisher: Frontiers Media SA
ISBN: 2889452247

Languages : en
Pages : 105
Book Description
The E-book "Nucleation and Crystallization of Glasses and Glass-Ceramics" highlights historic perspectives and current research in the field of glass-ceramic technology. Glass-ceramic technology is promising to provide us with materials of high strength, high toughness, unique electrical/electronic or magnetic properties, exceptional optical or unusual thermal or chemical properties. The greater diversity of microstructure-property arrangements and processing routes over glasses and ceramics are responsible that glass-ceramics are the preferred choice of materials in many technical, consumer, optical, medical/dental, electrical/electronic, and architectural fields. This includes increasing uses of glass-ceramic materials for environment and energy applications in the last decades. The positive development of glass-ceramic technology has become true in particular due to the pioneering spirit, resourcefulness, and courage of researchers of the first generation. Extraordinary and, therefore, to be distinguished is the work of the glass-ceramic inventor S. Donald Stookey to whom this Research Topic is dedicated. The authors, all experts in the field of glass-ceramics and based in industry, academia and governmental institutions, contributed to this E-book under the guidance of the Technical Committee 07 "Crystallization and Glass-Ceramics" of the International Commission on Glass (ICG).
The Baltic States, Years of Dependence, 1940-1990
Author: Romuald J. MisiunasPublisher: Univ of California Press
ISBN: 9780520082274
Category : History
Languages : en
Pages : 434
Book Description
In this updated edition of their renowned The Baltic States, Romuald Misiunas and Rein Taagepera bring the story of Lithuania, Latvia, and Estonia up to the 1990s. The authors describe and analyze how the Baltic nations survived fifty years of social disruption, language discrimination, and Russian colonialism. The nations' histories are fully integrated and compared, and some notable differences between them are pointed out. With two new chapters, a revised preface, and an appendix on the end of Soviet domination, this expanded study covers a tumultuous period of political, economic, cultural, and ecological reform.
Creative Space
Author: Andrzej P. WierzbickiPublisher: Springer Science & Business Media
ISBN: 9783540284581
Category : Mathematics
Languages : en
Pages : 316
Book Description
Creative Space summarizes and integrates the various up-to-date approaches of computational intelligence to knowledge and technology creation including the specific novel feature of utilizing the creative abilities of the human mind, such as tacit knowledge, emotions and instincts, and intuition. It analyzes several important approaches of this new paradigm such as the Shinayakana Systems Approach, the organizational knowledge creation theory, in particular SECI Spiral, and the Rational Theory of Intuition – resulting in the concept of Creative Space. This monograph presents and analyzes in detail this new concept together with its ontology – the list and meanings of the analyzed nodes of this space and of the character of transitions linking these nodes.

Author: Supranational Citizenship and the Challenge of Diversity
Author: Francesca StrumiaPublisher: Martinus Nijhoff Publishers
ISBN: 9004260765
Category : Law
Languages : en
Pages : 346
Book Description
In Supranational Citizenship and the Challenge of Diversity Francesca Strumia explores the potential of European citizenship as a legal construct, and as a marker of group boundaries, for filtering internal and external diversities in the European Union. Adopting comparative federalism methodology, and drawing on insights from the international relations literature on the diffusion of norms, the author questions the impact of European citizenship on insider/outsider divides in the EU, as experienced by immigrants, set by member states and perceived by “native” citizens. The book proposes a novel argument about supranational citizenship as mutual recognition of belonging. This argument has important implications for the constitution of insider/outsider divides and for the reconciliation of multiple levels of diversity in the EU.
