Unlike some other reproductions of classic texts (1) We have not
used OCR(Optical Character Recognition), as this leads to bad
quality books with introduced typos. (2) In books where there are
images such as portraits, maps, sketches etc We have endeavoured to
keep the quality of these images, so they represent accurately the
original artefact. Although occasionally there may be certain
imperfections with these old texts, we feel they deserve to be made
available for future generations to enjoy.
Among the several distinct ways of formulating and quantizing a
Hamiltonian system, the light cone approach enjoys special status
because it has the largest stability group. The aim of this volume
is to present recent achievements and open problems in this rather
unusual quantization framework to a large audience. The formulation
is set up in a comprehensive introduction where the issues are also
clearly indicated with specific examples: vacuum structure,
signature of non-perturbative effects, chiral symmetry breaking,
light cone gauge theories, etc. The following chapters address
these topics through a selection of the most relevant contributions
presented at Les Houches.
This volume should prove valuable to newcomers in the field, and
graduates and academics.

In a companion volume to their highly acclaimed book Overcoming the
Odds, Emmy E. Werner and Ruth S. Smith continue their longitudinal
study of approximately five hundred men and women who were born in
1955 on the Hawaiian island of Kauai. A third of these individuals
had been considered "at risk" because of birth complications,
parental mental illness, family dysfunction, and adverse early
conditions such as poverty. Werner and Smith examine the long-term
impact of these influences on the individuals' later adaptation to
life.Drawing on data collected by a team of psychologists,
pediatricians, social workers, and public health nurses across four
decades, Werner and Smith chronicle the development of these men
and women from birth to midlife: infancy, early and middle
childhood, late adolescence, and early and middle adulthood. Their
book focuses on protective factors within the individual, the
extended family, and the community that allowed most of the men and
women to be successful and to be satisfied with their lives by age
forty. Most important, the authors document the remarkable
resilience and capacity for recovery displayed by the majority of
these baby boomers, who approached middle age as competent,
confident, and caring adults. Journeys from Childhood to Midlife
highlights key turning points in the third and fourth decades of
life, and shows why more women than men succeeded in overcoming the
odds. The work addresses the policy implications of the research
and the need to evaluate and improve the effectiveness of current
intervention programs for children.
In den zuruckliegenden Jahren haben in London (1973),
Louvain-Ia-Neuve (1975) und New York (1977) 3 Symposien uber die
Biochemie der beiden Eisenstoffwechselproteine Ferritin und
Transferrin stattgefunden. Die rasche Aufeinanderfolge der Tagungen
zu einem so eng umrissenen Themenkreis dokumentiert ein neu
erwachtes Interesse an den bioche- mischen und
biologisch-medizinischen Aspekten dieser eisenspezifischen
Proteine. Zu dieser Intensivierung des Interesses verschiedener
wissenschaftlicher Fachgebiete hat die Entdeckung beigetragen, dass
Ferritin entgegen fruherer Auffassung in geringer Konzen- tration
ein normaler Bestandteil des zirkulierenden Blutes ist und sich als
Mass fur die Beurteilung der Koerpereisenreserven eignet. Das
Serumferritin ist damit zu einem fur die medizinische Diagnostik
wertvollen Para- meter geworden und hat Eingang in die
Routinediagnostik auf verschiedenen Gebieten der klinischen Medizin
gefunden. Das vorliegende Buch fasst die Beitrage zu einem am 13.
und 14. Oktober 1978 in Frank- furt am Main unter der
Schirmherrschaft der Deutschen Gesellschaft fur Hamatologie und
Onkologie durchgefuhrten Internationalen Symposium uber methodische
und klini- sche Aspekte des Serumferritins zusammen. Die
Herausgeber haben sich bemuht, die in den Referaten und in der
Diskussion sicht- bar gewordenen Differenzen zu zahlreichen
Problemen der Serumferritinbestimmung in ihrer kontroversen Form
wiederzugeben, da dem Symposium das Ziel gesetzt war, eine erste
Zusammenfassung vor allem der klinischen Erfahrungen mit dem neuen
Eisen- stoffwechselparameter Serumferritin zu geben. Es hat sich
gezeigt, dass trotz unterschied- licher Auffassungen in der
Beurteilung der Wertigkeit des Serumferritins in der klinischen
Anwendung diesem Parameter schon jetzt ein bedeutender Stellenwert
fur die Bewertung des Koerpereisenstatus zukommt.
