Cathodic arcs are among the longest studied yet least understood
objects in science. Plasma-generating, tiny spots appear on the
cathode; they are highly dynamic and hard to control. With an
approach emphasizing the fractal character of cathode spots,
strongly fluctuating plasma properties are described such as the
presence of multiply charged ions that move with supersonic
velocity. Richly illustrated, the book also deals with practical
issues, such as arc source construction, macroparticle removal, and
the synthesis of dense, well adherent coatings. The book spans a
bridge from plasma physics to coatings technology based on
energetic condensation, appealing to scientists, practitioners and
graduate students alike.

In the aftermath of an armed conflict in Africa, the international
community both produces and demands from local partners a variety
of blueprints on how to reconstruct state and society. The aim is
to re-formalize the state after what is viewed as a brief or
extended period of fragmentation and informalization caused by
armed conflict. In reality, both African economies and politics are
very much informal in character, with informal actors (including
so-called "Big Men") often using their positions in the formal
structure as a means to reach informal goals. Through a variety of
in-depth case studies - from DRC to Somali to Liberia among others
- this book shows how important informal political and economic
networks are in many of the continent's conflict areas. More than
this, it demonstrated that without a proper understanding of their
impacts in areas such as borderlands and in "narco-states" such as
Guinne-Bissau, attempts to "formalize" African states, particularly
those emerging from wars, will be in vain.

One of the most influential child psychiatrists of the twentieth
century, Donald J. Cohen (1940-2001) made groundbreaking
contributions to the study of autism and developmental
disabilities, Tourette's syndrome, developmental psychopathology,
child psychoanalysis, and children's adaptation to trauma. As
director of the Yale Child Study Center from 1983 to 2001, he
fostered international collaborations and innovative approaches to
the study of children's mental health. This book contains a
selection of some of his most enduring and influential writings.
Showcasing Dr. Cohen's distinctive approach, these essays - one of
which is published here for the first time - address a wide range
of topics including autobiographical writings; childhood
psychiatric disorders; the role of play fantasy, aggression, and
violence in childhood; and research ethics and mentorship.
