With the onset of massive cosmological data collection through
media such as the Sloan Digital Sky Survey (SDSS), galaxy
classification has been accomplished for the most part with the
help of citizen science communities like Galaxy Zoo. Seeking the
wisdom of the crowd for such Big Data processing has proved
extremely beneficial. However, an analysis of one of the Galaxy Zoo
morphological classification data sets has shown that a significant
majority of all classified galaxies are labelled as Uncertain .
This book reports on how to use data mining, more specifically
clustering, to identify galaxies that the public has shown some
degree of uncertainty for as to whether they belong to one
morphology type or another. The book shows the importance of
transitions between different data mining techniques in an
insightful workflow. It demonstrates that Clustering enables to
identify discriminating features in the analysed data sets,
adopting a novel feature selection algorithms called Incremental
Feature Selection (IFS). The book shows the use of state-of-the-art
classification techniques, Random Forests and Support Vector
Machines to validate the acquired results. It is concluded that a
vast majority of these galaxies are, in fact, of spiral morphology
with a small subset potentially consisting of stars, elliptical
galaxies or galaxies of other morphological variants."

A laboratory for competing visions of modernity, the Weimar
Republic (1918-1933) continues to haunt the imagination of the
twentieth century. Its political and cultural lessons retain
uncanny relevance for all who seek to understand the tensions and
possibilities of our age. "The Weimar Republic Sourcebook"
represents the most comprehensive documentation of Weimar culture,
history, and politics assembled in any language. It invites a wide
community of readers to discover the richness and complexity of the
turbulent years in Germany before Hitler's rise to power. Drawing
from such primary sources as magazines, newspapers, manifestos, and
official documents (many unknown even to specialists and most never
before available in English), this book challenges the traditional
boundaries between politics, culture, and social life. Its thirty
chapters explore Germany's complex relationship to democracy,
ideologies of 'reactionary modernism', the rise of the 'New Woman',
Bauhaus architecture, the impact of mass media, the literary life,
the tradition of cabaret and urban entertainment, and the situation
of Jews, intellectuals, and workers before and during the emergence
of fascism. While devoting much attention to the Republic's varied
artistic and intellectual achievements (the Frankfurt School,
political theater, twelve-tone music, cultural criticism,
photomontage, and urban planning), the book is unique for its
inclusion of many lesser-known materials on popular culture,
consumerism, body culture, drugs, criminality, and sexuality; it
also contains a timetable of major political events, an extensive
bibliography, and capsule biographies. This will be a major
resource and reference work for students and scholars in history;
art; architecture; literature; social and political thought; and,
cultural, film, German, and women's studies.
How did Daniel do it? How can one adhere to Christian values in a
corrupt world? How does one determine the most expedient path when
choosing the lesser of the evils? Born into a farming family in
Indiana, Jay Edwards, along with his wife and family, has been a
missionary and agricultural businessman in South America since
1987. Challenged by the difficulty of dealing first-hand with
decisions pertaining to bribes, extortion, threats, unfair bidding
processes, political favoritism, blackmail, kickbacks, and other
unethical practices, Edwards realized that the Daniel of the Bible,
in all probability, faced these issues also. If God could guide
Daniel in ancient Babylon, the cradle of perversity, then He could
surely guide the author through the labyrinth of politically
charged ethical dilemmas so often encountered in South American
bureaucracy. This fast-paced historical fiction poses possible
solutions for Daniel and his friends. The book includes as an
appendix, Issues Daniel Faced, which provides interesting questions
and themes which may be used as a discussion guide for similar
issues in our world today.

The first book in the Folklife in the South series and by far the
broadest look at traditional Cajun culture ever assembled. It not
only describes the traditions as they are but also explains how
they came to be.
This best-selling title will challenge, encourage, and aid the
reader in the development of a truly Christian home.
