We have conducted an experimental study of V-type electromagnetically induced transparency in sodium. Its principles are elucidated by a simple model. Measurements show decreased fluorescence and absorption depending on the detuning of the driving and probe fields, which is in agreement with the results of numerical simulation.

The nature of Marx's ethics has been a matter of considerable dispute since the latter part of the nineteenth century. Some have maintained that Marx had no ethics; others have claimed that his ethics is Kantian; and yet others have maintained that his ethics is utilitarian. The first two views were prominent at the turn of the century. It is the utilitarian view that seems to hold favor among a great many today. Thus Adam Schaff has claimed that ‘Marxist theory (...) … leads to the general position that may be called “social hedonism” —the view that the aim of human life is to secure the maximum happiness for the broadest masses of the people … ’ Similarly, Derek Allen has claimed that ‘it is possible … to show that the arguments which support [Marx's and Engels’] moral judgments are utilitarian in all but name.’.

This book addresses a wide range of topics relating to the properties and behavior of condensed matter under extreme conditions such as intense magnetic and electric fields, high pressures, heat and cold, and mechanical stresses. It is divided into four sections devoted to condensed matter theory, molecular chemistry, theoretical physics, and the philosophy and history of science. The main themes include electronic correlations in material systems under extreme pressure and temperature conditions, surface physics, the transport properties of low-dimensional electronic systems, (...) applications of the density functional theory in molecular systems, and graphene. The book is the outcome of a workshop held at the University of Catania, Italy, in honor of Professor Renato Pucci on the occasion of his 70th birthday. It includes selected invited contributions from collaborators and co-authors of Professor Pucci during his long and successful career, as well as from other distinguished guest authors. (shrink)

The theoretical and practical problems of providing incentives for people's activity in society are becoming increasingly more urgent as the role of the human factor in the development of society grows. In light of modern historical experience, we can see the onesidedness of conceptions according to which the types and directions of activity are mechanically predetermined by conditions external to it, and we can see the necessity of understanding the laws of activity itself in all their complicated dialectical essence. These (...) problems have become particularly important at the present stage of development of Soviet society, when a greater active involvement of the masses and profound changes in social psychology are becoming acutely necessary.

system reflected in Saussure's linguistic theory, and so influential in the great progress linguistic theory has made in this century. Indeed, Granger sees linguistic theory as expressing a paradigm for scientific theorizing, which research in other social sciences should adopt. But 'structuralism' as a method in science does not, in Granger's view, begin with Saussure and the linguists. It is nothing less than the strategy of all the sciences, both natural and social, since their beginnings. Now, 'structuralism' is a 'trendy' (...) term no less in Anglophone methodology than in Francophone philosophy. But Granger's employment of the term is not to be assimilated to this trend, nor to the fashionable excesses for which this expression has been a watch word (he explicitly separates himself from this movement in the preface to the second edition). The exact nature of what Granger calls 'structuralist' methods is the subject of a large part of this work, and I will not dwell on it much further in this introduction. Suffice it to say that Granger's demand for structuralist description is nothing less than the recognition that the successful pursuit of science requires that its terms and predicates pick out what we may call 'natural kinds'; that is, describe classes of items that bear uniform nomolog ical relations to one another. A science whose descriptive terms do not meet this condition will never produce any laws that reflect such nomological connections. (shrink)

Background: More and more quantitative information is becoming available about the risks of complications arising from medical treatment. In everyday practice, this raises the question whether each and every risk, however low, should be disclosed to patients. What could be good reasons for doing or not doing so? This will increasingly become a dilemma for practitioners.Objective: To report doctors’ views on whether to disclose or withhold information on low risks of complications.Methods: In a qualitative study design, 37 respondents were included. (...) Focus group interviews were held with 22 respondents and individual in-depth interviews with 15.Results: Doctors have doubts about disclosing or withholding information on complication risk, especially in a risk range of 1 in 200 to 1 in 10 000. Their considerations on whether to disclose or to withhold information depend on a complicated mix of patient and doctor-associated reasons; on medical and personal considerations; and on the kind and purpose of intervention.Discussion: Even though the degree of a risk is important in a doctor’s considerations, the severity of the possible complications and patients’ wishes and competencies have an important role as well. Respondents said that low risks should always be communicated when there are alternatives for the intervention or when the patient may prevent or mitigate the risk. When the appropriateness of disclosing risks is doubtful, doctors should always tell their patients that no intervention is without risk, give them the opportunity to gather all the information they need or want, and enable them to detect a complication at an early stage.

The authors deal with the classic paradox of ethical theories, “Hume’s guillotine,” based on the contradiction in morality between what is and what should be. At the same time, the theological justification of moral principles is beyond this criticism, because the sacred commandments “by definition” combine what is and what should be, overcoming the “secular” gap between being and duty, and thus “the problem of transition from description to evaluation is removed.” Modern ways of removing this contradiction, revealed by Hume, (...) are considered from several points of view. Special attention is paid to the analogy between the development of ethical and mathematical theories, a synergistic approach to the formation of ethics, as well as to the ethical choice associated with the development of digital reality, which humanity will face soon. A synergistic approach can be viewed as a bridge “over the abyss of two cultures - natural science and humanities.” Now it has become clear that there can be many logics, geometries, versions of analysis of infinitely small, etc. Ethics can also be constructed and then put into practice. A classic example is the ethical code of King Lycurgus. Separate ethical systems are not able to ensure the survival of humanity under extreme conditions. Existence of general ethical rules in global crises allows many to survive. Without them, everyone would die. True amazement is the fact that the eight Dyakonov phase transitions in human history completely coincide with the crises periodicity presented in the text of the Apocalypse, where crises are figuratively called “beasts.” Then a vivid picture is given, a picture of the civilization transformation into a post-singular state, which goes beyond the horizon of scientific forecast.
