The Birth of Physics (Paperback): Michel Serres The Birth of Physics (Paperback)
Michel Serres; Translated by David Webb, William James Ross
R788 R734 Discovery Miles 7 340 Save R54 (7%) Ships in 10 - 15 working days

The Birth of Physics represents a foundational work in the development of chaos theory from one of the world's most influential living theorists, Michel Serres. Focussing on the largest text still intact to reach us from the Atomists - Lucretius' De Rerum Natura - Serres mobilises everything we know about the related scientific work of the time (Archemides, Epicurus et al) in order to demand a complete reappraisal of the legacy. Crucial to his reconception of the Atomists' thought is a recognition that their model of atomic matter is essentially a fluid one - they are describing the actions of turbulence, which impacts our understanding of the recent disciplines of chaos and complexity. It explains the continuing presence of Lucretius in the work of such scientific giants as Nobel Laureates Schroedinger and Prigogine. This book is truly a landmark in the study of ancient physics and has been enormously influential on work in the area, amongst other things stimulating a more general rebirth of philosophical interest in the ancients.

A Psychology Classic
Originally presented by Anne Anastasi as an address of the President of the American Psychological Association in 1957 this child psychology and nature nurture debate classic argues that the question "How?" offers a much more constructive approach to the heredity-environment problem; as opposed to the question "Which one?" or "How much?"
Note To Psychology Students
If you ever have to do a paper, assignment or class project on the nature nurture debate having access to Heredity, Environment, and The Question "How?" in full will prove invaluable. A psychology classic is by definition a must read; however, most landmark texts within the discipline remain unread by a majority of psychology students. A detailed, well written description of a classic study is fine to a point, but there is absolutely no substitute for understanding and engaging with the issues under review than by reading the authors unabridged ideas, thoughts and findings in their entirety.
Bonus Material
Heredity, Environment, and The Question "How?" builds upon some of Anne Anastasi's previously published work. Among the most notable of these earlier publications is A Proposed Reorientation in the Heredity Environment Controversy; which is also presented in full.

A Psychology Classic
Albert Bandura is one of the world's most frequently cited psychologists. His ground-breaking work within the field of social learning and social cognitive theory led to a paradigm shift within psychology away from psychodynamic and behaviorist perspectives. As part of a new research agenda in the early 1960's which posited that people learn vicariously through observation Bandura began investigating aggression through imitation; work that gave rise to one of the most famous psychology studies of all time, "Transmission of Aggression Through Imitation of Aggressive Models." More commonly known as "The Bobo Doll Experiment," it was the first study to explore the impact of televised violence on children.

R182 Discovery Miles 1 820 Ships in 7 - 11 working days

Psychology Classics: The Case of Little Albert
Conditioned Emotional Reactions by John B. Watson and Rosalie Rayner is one of the most influential, infamous and iconic research articles ever published in the history of psychology. Commonly referred to as "The Case of Little Albert" this psychology classic attempted to show how fear could be induced in an infant through classical conditioning. Originally published in 1920, Conditioned Emotional Reactions remains among the most frequently cited journal articles in introductory psychology courses and textbooks.
A psychology classic is by definition a must read. However, most seminal texts within the discipline remain unread by a majority of psychology students. A detailed, well written description of a classic study is fine to a point, but there is absolutely no substitute for understanding and engaging with the issues under review than by reading the authors unabridged ideas, thoughts and findings in their entirety.
Bonus Material:
One of the most dramatic aspects of Watson and Rayner's original study was that they had planned to test a number of methods by which they could remove Little Albert's conditioned fear responses. However, as Watson noted "Unfortunately Albert was taken from the hospital the day the above tests were made. Hence the opportunity of building up an experimental technique by means of which we could remove the conditioned emotional responses was denied us."
This unforeseen turn of events was something that obviously stayed with Watson, as under his guidance some three years later, Mary Cover Jones conducted a follow-up study - A Laboratory Study of Fear: The Case of Peter - which illustrated how fear may be removed under laboratory conditions. This additional and highly relevant article is also presented in full.

A Psychological Analysis of Adolf Hitler (Paperback): David Webb A Psychological Analysis of Adolf Hitler (Paperback)
David Webb; Walter Langer
R349 Discovery Miles 3 490 Ships in 7 - 11 working days

In 1943 William Donovan the director of the Office of Strategic Services (the forerunner to the CIA) approached Harvard psychologist Walter Langer and asked him to construct a psychological profile of Adolf Hitler.
Despite his reservations regarding the reliability of the data upon which his analysis would be based, Langer set about this unprecedented task by putting together a team of psychologists and researchers. Langer and his research team had just five months to produce their findings, in which time they interviewed key informants who knew Hitler personally and drew upon over 1000 pages of background research from a document known as The Hitler Source Book.
In order to try and understand Hitler as a person and the motivations underlying his actions, Langer presents his psychological profile within five specific sections
1. Hitler as he believes himself to be.
2. Hitler as the German people know him.
3. Hitler as his associated know him.
4. Hitler as he knows himself.
5. Psychological analysis and reconstruction.
Freudianism at its Height
In constructing a psychological analysis of Hitler, Langer drew heavily upon the ideas of Sigmund Freud, most notably the developmental influence of early childhood experiences. As such the report provides the reader with a fascinating window into the mechanics of Freudian analysis. Among the issues discussed within this paradigm are:
Hitler's character as influenced by his father.
Hitler's mother and her influence.
Hitler's attitude towards love, women and marriage.
Hitler's early conflicts expressed in symbolic form.
The Messiah Complex.
Desire for immortality.
Hitler's Sexual development.
A Classic in The History of Psychology
Langer's report on Adolf Hitler not only showcased the dominant discourse of psychological analysis at the time, but it also served as the catalyst for the development of political profiling as a discipline.
Psychology Gets Political
Without doubt the greatest legacy of Langer's report was the influence it had on the field of political profiling. Dr Jerrold Post cites Langer's analysis of Hitler as the inspiration for the profiling unit he established at the CIA in the 1970s; which would subsequently go on to profile every important world leader up to and including Saddam Hussein.
In discussing Langer's psychological profile of Hitler during an interview with the BBC, Post stated:
""We must understand the leaders we are contending with - you can't deter optimally a leader you don't understand - and to relegate be it a Hitler or a Joseph Stalin or a Saddam Hussein to a crazy evil madman really degrades our capacity to deal with them optimally because we're not thinking about what pushes them, what makes them tick.""
While the value of political profiling remains open to question, the seminal importance of Langer's psychological study of Hitler in influencing the discipline is not.

Two rather different elements combine to explain the origin of this volume: one scientific and one personal. The broader of the two is the scientific basis-the time for such a volume had arrived. Geology had made remarkable progress toward an understanding of the phys ical history of the Caribbean Basin for the last 100 million years or so. On the biological side, many new discoveries had elucidated the distributional history of terrestrial orga nisms in and between the two Americas. Geological and biological data had been combined to yield the timing of important events with unprecedented resolution. Clearly, when each of two broad disciplines is making notable advances and when each provides new insights for the other, the rewards of cross-disciplinary contacts increase exponentially. The present volume represents an attempt to bring together a group of geologists, paleontologists and biologists capable of exploiting this opportunity through presentation of an interdisciplinary synthesis of evidence and hypothesis concerning interamerican connections during the Cretaceous and Cenozoic. Advances in plate tectonics form the basis for a modern synthesis and, in the broadest terms, dictate the framework within which the past and present distributions of organisms must be interpreted. Any scientific dis cipline must seek tests of its conclusions from data outside of its own confines."

In 1980, Furchgott and Zawadzki demonstrated that the ability of a blood vessel to relax to acetylcholine is entirely dependent upon the presence of an intact endothelium b1. This startlingly simple and elegant observation heralded a decade of basic research into endothelium-derived vasoactive factors (EDRF). Initially, interest focused on Furchgott's endothelium-derived relaxing factor, which was later identified as the extremely simple molecule, nitric oxide [21. However, bioassay systems suggested the presence of other dilator and constrictor factors. Many of these additional putative factors remain elusive but one constrictor factor was revealed to the world in an impres- sively complete piece of science published in 1988. Yanagisawa, Masaki and colleagues [31 demonstrated the synthesis of a twenty one amino acid peptide which accounted for the constrictor activity found in the supernatant of endothelial cells. They identi- fied its structure, synthesised the peptide, showed its biological activity in vitro and in vivo, proposed mechanisms of action and cloned and sequenced the gene. They named the factor endothelin. The identification of nitric oxide and endothelin has also rekindled interest in established endothelium-derived mediators, including the prostanoids and other arachidonic acid metabolites, and has led to exploration of the possible roles of oxygen radicals such as superoxide. The vascular endothelium has become a major focus for research into disease states or cardiovascular risk factors associated with abnormal vascular tone or reactivity, alterations in cellular adhesion to the vessel wall, increased smooth muscle cell growth and the chronic process of atherogenesis.
