This book casts the theory of periods of algebraic varieties in the
natural setting of Madhav Nori's abelian category of mixed motives.
It develops Nori's approach to mixed motives from scratch, thereby
filling an important gap in the literature, and then explains the
connection of mixed motives to periods, including a detailed
account of the theory of period numbers in the sense of
Kontsevich-Zagier and their structural properties. Period numbers
are central to number theory and algebraic geometry, and also play
an important role in other fields such as mathematical physics.
There are long-standing conjectures about their transcendence
properties, best understood in the language of cohomology of
algebraic varieties or, more generally, motives. Readers of this
book will discover that Nori's unconditional construction of an
abelian category of motives (over fields embeddable into the
complex numbers) is particularly well suited for this purpose.
Notably, Kontsevich's formal period algebra represents a torsor
under the motivic Galois group in Nori's sense, and the period
conjecture of Kontsevich and Zagier can be recast in this setting.
Periods and Nori Motives is highly informative and will appeal to
graduate students interested in algebraic geometry and number
theory as well as researchers working in related fields. Containing
relevant background material on topics such as singular cohomology,
algebraic de Rham cohomology, diagram categories and rigid tensor
categories, as well as many interesting examples, the overall
presentation of this book is self-contained.
Few would dispute that many Western industrial democracies
undertook extensive deregulation in the 1970s and 1980s. Yet this
narrative, in its most familiar form, depends upon several
historiographical assumptions that bely the complexities and
pitfalls of studying the recent past. Across thirteen case studies,
the contributors to this volume investigate this "deregulatory
moment" from a variety of historical perspectives, including
transnational, comparative, pan-European, and national approaches.
Collectively, they challenge an interpretive framework that treats
individual decades in isolation and ignores broader trends that
extend to the end of the Second World War.

This book is thematically positioned at the intersections of Urban
Design, Architecture, Civil Engineering and Computer Science, and
it has the goal to provide specialists coming from respective
fields a multi-angle overview of state-of-the-art work currently
being carried out. It addresses both newcomers who wish to obtain
more knowledge about this growing area of interest, as well as
established researchers and practitioners who want to keep up to
date. In terms of organization, the volume starts out with chapters
looking at the domain at a wide-angle and then moves focus towards
technical viewpoints and approaches.
This book contains the final versions of the proceedings of the
fifth EUROGRA PHICS Workshop on Rendering held in Darmstadt,
Germany, between 13-15 June 1994. With around 80 participants and
30 papers, the event continued the successful tradition of the
previous ones establishing the event as the most im portant meeting
for persons working on this area world-wide. After more than 20
years of research, rendering remains an partially unsolved,
interesting, and challenging topic. This year 71 (!) papers have
been submitted from Europe, North America, and Asia. The average
quality in terms of technical merit was impressive, showing that
substantial work is achieved on this topic from several groups
around the world. In general we all gained the impression that in
the mean time the technical quality of the contributions is
comparable to that of a specialised high-end, full scale
conference. All papers have been reviewed from at least three
members of the program committee. In addition, several colleagues
helped us in managing the reviewing process in time either by
supporting additional reviews, or by assisting the members of the
committee. We have been very happy to welcome eminent invited
speakers. Holly Rush meier is internationally well known for her
excellent work in all areas of rendering and gave us a review of
modelling and rendering participating media with em phasis on
scientific visualization. In addition, Peter Shirley presented a
survey about future rends in rendering techniques.
The subject of algebraic cycles has thrived through its interaction
with algebraic K-theory, Hodge theory, arithmetic algebraic
geometry, number theory, and topology. These interactions have led
to such developments as a description of Chow groups in terms of
algebraic K-theory, the arithmetic Abel-Jacobi mapping, progress on
the celebrated conjectures of Hodge and Tate, and the conjectures
of Bloch and Beilinson. The immense recent progress in algebraic
cycles, based on so many interactions with so many other areas of
mathematics, has contributed to a considerable degree of
inaccessibility, especially for graduate students. Even specialists
in one approach to algebraic cycles may not understand other
approaches well. This book offers students and specialists alike a
broad perspective of algebraic cycles, presented from several
viewpoints, including arithmetic, transcendental, topological,
motives and K-theory methods. Topics include a discussion of the
arithmetic Abel-Jacobi mapping, higher Abel-Jacobi regulator maps,
polylogarithms and L-series, candidate Bloch-Beilinson filtrations,
applications of Chern-Simons invariants to algebraic cycles via the
study of algebraic vector bundles with algebraic connection,
motivic cohomology, Chow groups of singular varieties, and recent
progress on the Hodge and Tate conjectures for Abelian varieties.

Current therapies for most human genetic diseases are inadequate.
In response to the need for effective treatments, modern molecular
genetics is providing tools for an unprecedented new approach to
the treatment of diseases; e.g. the direct manipulation of mutant
genes or the input on new therapeutic genes. The treatment of human
disease by gene transfer has now moved from the theoretical to the
practical realm. With the initiation of clinical trials involving
somatic gene therapy in different countries, a critical assessment
of the different aspects involved with this new technique is
necessary. This volume provides an overview on all these
interdisciplinary aspects by some well known experts all over the
world.
Collating different aspects of Vector-valued Partial Differential
Equations and Applications, this volume is based on the 2013 CIME
Course with the same name which took place at Cetraro, Italy, under
the scientific direction of John Ball and Paolo Marcellini. It
contains the following contributions: The pullback equation
(Bernard Dacorogna), The stability of the isoperimetric inequality
(Nicola Fusco), Mathematical problems in thin elastic sheets:
scaling limits, packing, crumpling and singularities (Stefan
Muller), and Aspects of PDEs related to fluid flows (Vladimir
Sverak). These lectures are addressed to graduate students and
researchers in the field.
"Bilanzanalyse" stellt umfassend, anwendungsorientiert und auf
aktuellstem Stand das Instrumentarium fur eine gezielte Auswertung
des Jahresabschlusses vor. Behandelt wird die Analyse sowohl von
Einzel- und Konzernabschlussen wie auch von Abschlussen nach HGB
und nach internationalen Standards. Viele Unternehmensbeispiele
verdeutlichen die Analysemethoden und -aussagen und schaffen so die
Verbindung zur praktischen Umsetzung.
Dichotomien erleichtern das Denken. Sie geben Orientierung, sind
Grundlage von rationalen Entscheidungen, geben Anleitung zur
Systematisierung und nicht selten zur Bewertung. An ihre Grenzen
gerat eine binare Logik, wenn sich Phanomene nicht innerhalb einer
zweiwertigen Ordnung bestimmen lassen. Die Uberfuhrung starrer,
dualistischer (Denk-)Formen in eine erweiterte Verhaltnisbestimmung
bildet den Anspruch sozialwissenschaftlicher Ansatze, die an Hegel
und Adorno anschliessen. Ein bestimmter Widerspruchstyp gilt ihnen
als produktive Kategorie. Der Sammelband stellt Elemente einer
dialektischen Theorie zur Diskussion."
Soziale Arbeit ist eine personenbezogene Arbeit. Sie vollzieht sich
im Wesentlichen zwischen Personen, wovon in der Regel eine
hilfebedurftig und die andere unterstutzend bzw. anleitend ist.
Personen als beruflich Tatige bzw. Handelnde sind damit das
wichtigste Medium in der Sozialen Arbeit. Dieses Buch greift
erstmalig diesen Themenbereich sowohl aus der Historie und Theorie
als auch im Hinblick auf die diversen Tatigkeitsfelder auf.
Gleichzeitig wird der Frage der Qualifizierung der
Erzieherpersonlichkeiten nachgegangen und wie sich diese uber die
Berufsjahre hinweg erhalten lasst.
In einer Gesellschaft, in der sich - nicht zuletzt hervorgerufen
durch die Globalisierung - der Wettbewerb zunehmend verscharft und
gleichzeitig die meisten Markte gesattigt sind, kommt der
Kundenbindung eine immer bedeutendere Rolle zu. Im vorliegenden
Band wird dieses Thema von fuhrenden Personlichkeiten aus der Sicht
der Werbewirtschaft, des europaischen und nordamerikanischen
Handels, der Mittelstandes und des Marketing beleuchtet.
Anschliessend werden die wissenschaftlichen Arbeiten der
diesjahrigen Preistrager des Otto-Beisheim-Forderpreises in Form
von Kurzdarstellungen vorgestellt."
Die Autoren stellen die verschiedenen Aspekte des Technikrechts dar
und orientieren sich dabei an den Managementbereichen, wie sie in
Unternehmen vorzufinden sind (Produktionsmanagement,
Qualitatsmanagement, technisches Vertriebsmanagement,
Risikomanagement, Umweltmanagement, Projektmanagement,
Wissensmanagement). Das Werk bereitet den aktuellen Stand von
Rechtsprechung und Rechtswissenschaft auch fur Nicht-Juristen
verstandlich auf. Es zeigt Handlungsempfehlungen und Strategien fur
den Umgang mit der rechtlichen Lage auf.
Das Buch wendet sich an alle, die in die klassischen Themen der
Zahlentheorie einsteigen wollen. Viel Wert wird auf die konkrete
Berechenbarkeit bei allen Problemlosungen gelegt. So gibt es auch
Abschnitte uber moderne Primzahltests und
Faktorisierungsalgorithmen und am Ende des Buches wird ein Weg zur
Bestimmung der Klassenzahl der quadratischen Zahlkorper
aufgezeigt.
Im Rahmen der Bachelor-/Master-Studiengange eignet sich das Buch
als Grundlage fur zwei Semester: ein Aufbaumodul in elementarer
Zahlentheorie mit einem Vertiefungsmodul in algebraischer
Zahlentheorie.
"
Stefan Hoffmann stellt dar, weshalb sich Konsumenten an einem
Boykott beteiligen. Er entwickelt ein umfassendes, empirisch
validiertes Modell des politisch motivierten Kaufverhaltens, auf
dessen Basis sich Implikationen fur Manager und politische Akteure
ableiten lassen."
Das Rechnungswesen gehoert zu den zentralen Unternehmensbereichen.
Neben der Abbildung interner Vorgange im Rahmen des Controllings
bildet es auch die Basis fur die extern orientierte
Unternehmensrechnung. Beide Teilgebiete haben sich in den letzten
Jahren dynamisch entwickelt. Entsprechend komplex und kontrovers
ist die Diskussion in Wissenschaft und Praxis. In "Controlling und
Rechnungslegung" bieten renommierte Fachexperten eine ausgewogene
Mischung aus neuesten wissenschaftlichen Erkenntnissen und
aktuellen Beispielen.
The book is concerned with a particular set of Indo-European
sounds, the laryngeals, and the effect they had on the sounds,
forms and etymologies of the Germanic languages. It contains
detailed introductions to all the fundamentals of laryngeal theory,
together with an introduction to the problematic history of the
laryngeal theory which can be read without specialist knowledge.
Research into the Germanic languages has not previously taken
account of laryngeal theory, but with it many a sound law,
etymology and morphological development can be reformulated or made
more precise.
