This book attempts to prepare the non-philosopher for the study of contemporary philosophical works. After a discussion of the course of science after Copernicus, Mr. Prosch turns to an exposition of, first, the metaphysical and epistemological positions of the British empiricists and Kant and, second, the ethical and political positions of Hobbes, Locke, Hume, Adam Smith, Kant, Rousseau, and Hegel. His discussion of Marxism, pragmatism, analytical philosophy and existentialism is written from a neutral position. The book may be too technical (...) to serve its purpose, but it is a well-organized and clear attempt.—J. M. B. (shrink)

This book's purpose is the exposition of the inability of natural science to disprove the existence of God. Clark argues that the acceptance of a mechanistic world view based on Newtonian science makes, unjustifiably, a philosophy of science in which science forgets the many idealizations built into its laws' mathematical formulations. The philosophy of science Mr. Clark espouses is Percy Bridgman's operationalism, i.e., the reduction of the meaning of a concept to the operations used to measure it. The separation of (...) the physical world from what the scientist says about it leads Clark to deny that science is cognitive. It is, rather, a way of increasing nature's utility. As such, it may not be used to support any ethical position whatever.—J. M. B. (shrink)

In a series of essays, Miss Rand expounds her "Objectivist Ethics." Man will discover, if he is sufficiently rational, those goals and values which are peculiar to him alone, i.e., those which will enable him to survive, and which require complex thought processes. The result of this search is that the moral man is he who achieves his maximum happiness; relationships, whether economic or emotional, are to be based on trade, and no interests conflict if they are viewed in a (...) properly wide context. The essays are quite readable, although not so arresting as Miss Rand's novels; however, the ethics collapses when it is applied to a populous society whose environment is either agriculturally poor or highly mechanized. Given these conditions, if a man views his interest from the limited standpoint of Objectivism, there is a necessary conflict of interests.—J. M. B. (shrink)

Essays on Gilbert, Bacon, Galileo, Kepler, Harvey, van Helmont, and Descartes attempt, at a medium level of complexity, to relate the positions of these men to twentieth century views of the same questions. The stated purpose of the book is the assessment of the role of each man in the "methodological revolution"; although the methods are discussed, little attempt is made to put them into the context necessary for the reader to view them as revolutionary.—J. M. B.

The subtitle of this essay can be misleading; the author devotes only one preliminary chapter and a brief part of another chapter to discussing issues of scientific language and method. The book is primarily an essay in the philosophy of mind. Rosenblueth is a well-known neurophysiologist who has considerable background in the philosophy of science. His purpose is to articulate a general philosophical position that is consistent with the results of science as well as with the attitudes and activities of (...) experimental scientists; and to develop from this basis an answer to the question of how mind and brain are related. He spends four chapters summarizing the biological and neurophysiological research that shows the nature of the correlation between mental and neurophysiological events. He concludes from this that our knowledge of the material world is limited to those structures that can be coded by the afferent fibers. He then articulates four unprovable "postulates" which scientists must assume. One of these is a probabilistic statement of causal determinism. This postulate is the basis for his rejecting the idea that the mind can causally influence the brain through volitions. Moreover, he argues for the converse statement as well; the brain cannot cause conscious events since the latter are mental and not material. But this denial of causal interaction does not lead Rosenblueth to conclude that mind/body dualism must be rejected. He considers and rejects the monist views of Feigl, Russell and Eddington, and thus comes up with a dualist view that denies causal interaction. Although the scientific material cited by Rosenblueth is up to date, he does not consider the current philosophical discussions on the mind/body problem.--J. M. B. (shrink)

This book is of little interest except to those tracing back the neo-scholastic sources of such figures as Maréchal, Coreth, Rahner, et al. The introductory essay by G. Isaye, supposedly designed to give a summary description of Scheurer's method, is a masterpiece of obscure writing even for those acquainted with neoscholastic jargon. The rest of the volume consists of twelve very desultory essays by Scheurer. In these essays Scheurer struggles to pour the philosophy of the ego à la Kant and (...) his successors into scholastic molds. This synthesis is done in the name of the transcendental method, but what results is historically dubious and philosophically tortured. Though ambiguities abound, Scheurer was ahead of most of his scholastic contemporaries in that he tried to come to grips with Kant and to see in Kant someone more than the malin genie of modern philosophy. Unfortunately, the editor does not date Scheurer's essays and one, therefore, cannot determine whether Scheurer first influenced Maréchal or vice-versa--D. J. M. B. (shrink)

We formulate and analyze the dynamics of an influenza pandemic model with vaccination and treatment using two preventive scenarios: increase and decrease in vaccine uptake. Due to the seasonality of the influenza pandemic, the dynamics is studied in a finite time interval. We focus primarily on controlling the disease with a possible minimal cost and side effects using control theory which is therefore applied via the Pontryagin’s maximum principle, and it is observed that full treatment effort should be given while (...) increasing vaccination at the onset of the outbreak. Next, sensitivity analysis and simulations (using the fourth order Runge-Kutta scheme) are carried out in order to determine the relative importance of different factors responsible for disease transmission and prevalence. The most sensitive parameter of the various reproductive numbers apart from the death rate is the inflow rate, while the proportion of new recruits and the vaccine efficacy are the most sensitive parameters for the endemic equilibrium point.

Loop regions in proteins have traditionally been described as ‘random coil’, although they are known to adopt well‐defined conformations in most globular proteins. In this contribution we summarize the results of detailed analysis of the structures and sequences of these loop regions in proteins of known three‐dimensional structure. We also describe how these results can be used as an aid to protein design, modification and modelling.
