This book focuses on recent advances in the rapidly evolving
field of single molecule research. These advances are of importance
for the investigation of biopolymers and cellular biochemical
reactions, and are essential to the development of quantitative
biology. Written by leading experts in the field, the articles
cover a broad range of topics, including quantum photonics of
organic dyes and inorganic nanoparticles and monitoring of single
molecule (enzymatic) reactions.
Eyesight is one of our most precious possessions, and it lets us
enjoy our life to the fullest and appreciate the world around us.
We use our eyes every day, but we don't think much about how they
work.Written by two experts on the eye, "Our Eyes and Our Vision"
explains the miracle of eyesight. You'll discover what can go wrong
with your vision, how to prevent and cure problems, how ancient
scholars treated ocular diseases, and what the future has in store
for helping to protect and restore vision.Some eyesight problems
can be prevented or corrected, but others can only be postponed.
It's critical to understand the landscape so that problems can be
avoided or addressed as soon as possible.You'll gain deep insights
into how we see, and you'll also learn how we've gained knowledge
about treating eye diseases over the years. Whether you are a
nurse, ophthalmology assistant, emergency medical technician, or
just an average reader wanting to protect and restore your
eyesight, you'll be fascinated by "Our Eyes and Our Vision."
The Phenomenon of Religion proposes a new way of seeing the
bifurcation (a division into two parts or branches) within the
religious phenomenon of pagan and biblical religions. In contrast
to seeing the bifurcation as monotheism and polytheism, Dr. Manfred
Vogel argues for viewing the separation in terms of the "Buberian
bifurcation" that divides the It-dimension and the Thou-dimension.
The "It-dimension meaning: entities constituting themselves in
terms of physical nature, i.e. entities that ultimately ground
themselves in a dimension-of-power exemplified by many of their
characterizations. The "Thou-dimension" meaning: entities
constituting themselves in terms of personhood, i.e. to entities
that ultimately ground themselves in the dimension of
consciousness. On the basis of a fundamental division in religions,
this work presents the case that in contrast to pagan religion,
which grounds itself exclusively within the dimension of power,
biblical religion grounds itself within the dimension of
consciousness-instead of having a God as a power, it gives us God
as a person. This revolutionary innovation raises some serious
difficulties by biblical religion retaining its hold within the
dimension of power. The book proceeds to analyze in detail this
problematic innovation and indeed to show that the various
expressions constituting biblical religion-Halachic Judaism,
Christianity, and Islam-distinguish themselves from each other by
varying degrees by which they divide their grounding between power
and consciousness. Dr. Vogel's conclusion on the phenomenon of
religion concerns secular modernity and its influence over the
history and future of religion, particularly Halachic Judaism's
emancipation under the "enlightenment" of modernity.
Despite all the writing and the research, America's health care
industry continues to fail at providing health care that is
accessible and affordable, with measurable quality. The fundamental
reason we have failed is that health care is not only a complex
business, but the most complex in our economy. Other industries are
disrupted, some readily adapt to new markets; some leverage
information technology and innovative and cost-saving ways. But to
date, health care has resisted. The customary approaches tried in
other industries seem not to apply to health care. Why? Why is the
health care industry so politically divisive? Why is the quality of
health care services so difficult to measure? Why do patients often
fail to understand their own health care? Why are security and
privacy such unique challenges in health care? Why is the payment
process for health care services so complicated and challenging?
This book seeks to answer these questions. This book written by a
well know industry 'insider' with 35+ years working at senior
levels in hospital operations and information technology, discusses
nine major factors that in combination contribute to health care's
complexity. The author concludes that until we understand why
health is so complex, we will continue to see books complaining
about the poor state of health care in the U.S., and proposals for
change that are generally unsuccessful, and innovative technology
products that fail to deliver expected results.
Es werden immer Grenzfalle auftreten, die sich nur schwer oder gar
nicht einer der beiden Gruppen eindeutig zuordnen lassen. Mancher

("Mitessen am gleichen Tisch") und Mutualismus ("gegenseitige"
Hille, auf die die Partner nicht angewiesen sind); hierher gehoren
viele aus der Zoologie her wohlbekannte Beispiele, die friiher
vielfach irrtiimlich als Symbiosen gekennzeichnet wurden, wie das
Zusammenleben der Seeanemone mit dem Einsiedlerkrebs u. a. Wenn
auch beide eng zusammenleben, so sind sie doch nicht aufeinander
angewiesen, sondern konnen auch fiir sich aHein existieren. Als

CAMERON (1956) steht auf dem Standpunkt, daB bei dem gegenwartigen
Stand unserer Kenntnisse eine wissenschaftliche Definition des
Begriffes "Parasitismus" nicht moglich sei, und stellt einfach
fest: "Ein Parasit ist ein Organismus, der einen Wirt hat" ("A
parasit is an organism which has a host"). Dabei liegt auch das
Bestreben zugrunde, von jeglichem anthropozentrischen oder
okonomischen Gesichtspunkt abzusehen und das biologische Phanomen
des Zusammenlebens zweier artverschiedener Organismen an sich zu
betrachten. Aber dieses durchaus verstandliche Bemiihen iibersieht
dabei die Tatsache, daB die Wirkung eines Mikroorganismus, der auf
oder in einem Wirt lebt, fiir den Partner recht ver. schieden sein
kann (vgl. unten, S.9, 17 und 41ff.)."
Man erziihlt von Enrico Fermi, er habe nie eine wissenschaftliche
Veroffentli- chung gelesen. Er las nur die ersten Zeilen, die
aussagen sollten, was der Autor vorhatte. Sagten Sie das nicht,
warf er die Arbeit gleich weg. Sagten sie es, legte er sie etwas
sanfter beiseite, nahm einen Zettel und rechnete alles selbst aus.
Manchmal bekam er weniger heraus als der Autor, manchmal aber auch
mehr. Diese Arbeitsweise birgt fiir uns Nicht-Fermis gewisse
Gefahren, ist aber zweifellos besser als ihr weit verbreitetes
Gegenteil, fUr das gilt: "Was man sich eine Woche vor dem Examen
eingepaukt hat, vergiBt man in der Woche danach wieder". Man
braucht nicht Lempsychologie zu studieren, urn zu wissen, daB
produktives Lemen nicht nur viel fruchtbarer, sondem vor allem taus

Ich habe versucht, solche Probleme zusammenzustellen. Natiirlich
gibt es fast so viele verschiedene Meinungen dariiber, was
interessant ist, wie es Menschen gibt, und ebenso dariiber, ob
etwas leicht oder schwer oder wenig- stens klar formuliert ist. Ich
habe schon viele Schatzsuchen organisiert, bei denen ich mich fast
schiimte und dachte, bei so glasklaren Hinweisen miiBten doch die
Leute nach einer Minute direkt zum Versteck hinspazieren - und
abends urn zehn hatten sie den Schatz immer noch nicht. Ganz
entsprechend war es iibrigens auch, wenn ich mitsuchen muBte, was
ein anderer "ganz leicht" versteckt hatte.

This early work on brewing is both expensive and hard to find in
its first edition. It contains a wealth of information on the
processes involved in beer production. This is a fascinating work
and highly recommended for anyone interested in the brewing
industry and its history. Many of the earliest books, particularly
those dating back to the 1900s and before, are now extremely
scarce. We are republishing these classic works in affordable, high
quality, modern editions, using the original text and artwork.

Die Krise des gesellschaftlichen Naturverh ltnisses zeichnet sich
immer deutlicher ab. Gleichzeitig waren alle bisherigen Bem hungen
einschlie lich des Nachhaltigkeitsdiskurses und die ihm folgenden
Anstrengungen der Berufsbildung weitgehend erfolglos, der
Naturkrise wirksam zu begegnen. Woran liegt das und wie m sste
berufliche Bildung gestaltet werden, damit mehr Hoffnung besteht?
In dem Buch werden zun chst die zahlreichen Widerspr che im
industriegesellschaftlichen Naturverh ltnis untersucht. Die
kritische Analyse dieser Widerspr che liefert die Grundlage f r
eine neue, naturgem e Berufsbildungstheorie. Mit Vorschl gen zur
konkreten Umsetzung wendet sich das Buch abschlie end auch an
Bildungspraktiker.
Seit vielen Jahren besteht sowohl in der wissenschaftlichen als
auch in praktischen Diskussion Uneinigkeit hinsichtlich der
berlegenheit eines passiven bzw. aktiven Portfoliomanagements. Im
Rahmen dieser Diskussion st tzen sich die Anh nger des passiven
Portfoliomanagements auf die allgemein akzeptierten Erkenntnisse
des Capital Asset Pricing Models. Nach diesem Paradigma wird eine
positive Rendite lediglich f r den vom Anleger bernommenen und vom
Markt verg teten Anteil am systematischen Marktrisiko gezahlt.
Folglich besteht das Ziel dieses Ansatzes darin, durch eine m
glichst breite Diversifikation an der Marktrendite zu
partizipieren, wobei die Umsetzung dieses Ansatzes meist ber die
Anlage in einen In-dexfonds erfolgt. Der Vorteil des passiven
Portfoliomanagementansatzes f r den Anleger besteht darin, dass
sich eine solche sog. Beta-Performance zu u erst geringen Kosten
realisieren l sst, wobei eine Outperformance nicht angestrebt wird.
Die Anh nger des aktiven Portfoliomanagements glauben hingegen,
dass es durch das Timing des Gesamtmarktes und/oder die Selektion
von Einzelaktien seitens eines erfahrenen Portfoliomanagers
durchweg m glich ist, eine um das systematische Marktrisiko
adjustierte Mehrrendite zu erwirtschaften. Eine solche sog.
Alpha-Performance ist jedoch wesentlich schwieriger zu erzielen und
meist mit deutlich h heren Kosten verbunden. In dieser Studie
sollen Konzepte er rtert werden, wie ein Anleger eine
Alpha-Performance auch ber Exchange Traded Funds (ETFs), welche
eine besonders effiziente Kategorie von passiven Indexfonds
darstellen, erzielen kann. Hierzu werden zu Beginn der Studie die
Merkmale von ETFs erl utert. Im daran anschlie enden Kapitel werden
die theoretischen Grundlagen einer Outperformance mittels ETFs
diskutiert. Hierzu wird zuerst auf die klassische Einteilung
zwischen dem aktiven sowie passiven Portfoliomanagementansatz
eingegangen. Ferner wird gezeigt, dass das systematische
Marktrisiko nicht das einzige systematische R
