Isolated neutron stars undergoing non-radial oscillations are expected to emit gravitational waves in the kilohertz frequency range. To date, radio astronomers have located about 1,300 pulsars, and can estimate that there are about 2×108 neutron stars in the galaxy. Many of these are surely old and cold enough that their interiors will contain matter in the superfluid or superconducting state. In fact, the so-called glitch phenomenon in pulsars (a sudden spin-up of the pulsar's crust) is best described by assuming the (...) presence of superfluid neutrons and superconducting protons in the inner crusts and cores of the pulsars. Recently there has been much progress on modelling the dynamics of superfluid neutron stars in both the Newtonian and general relativistic regimes. We will discuss some of the main results of this recent work, perhaps the most important being that superfluidity should affect the gravitational waves from neutron stars (emitted, for instance, during a glitch) by modifying both the rotational properties of the background star and the modes of oscillation of the perturbed configuration. Finally, we present an analysis of the so-called zero-frequency subspace (i.e., the space of time-independent perturbations) and determine that it is spanned by two sets of polar (or spheroidal) and two sets of axial (or toroidal) degenerate perturbations for the general relativistic system. As in the Newtonian case, the polar perturbations are the g-modes which are missing from the pulsation spectrum of a non-rotating configuration, and the axial perturbations should lead to two sets of r-modes when the degeneracy of the frequencies is broken by having the background rotate.

Time, of course, will provide the opportunity for a deeper and fuller contemplation of the historical significance of the June 1983 Plenum of the Central Committee of the CPSU. But even now it is clear that it went far beyond the mere examination of current questions of the ideological and general political work of the party, above all because the speech of the General Secretary of the Central Committee of the CPSU, Comrade Iu. V. Andropov set forth the most important (...) theoretical positions having to do with the preparation of the new version of the program of the CPSU, positions which over the long term will determine the activity of the party and the nation and the development of Soviet society. The importance of the plenum also consisted in the fact that its proceedings brought to light the full scope of the tremendous role played by ideology, by the ideological struggle, and by ideological activity in today's world. There is a struggle going on between two polar opposite world outlooks, two political courses, socialism and imperialism, which is unprecedented throughout the entire postwar period as regards its intensity and ascerbity. There is a struggle taking place for the hearts and minds of billions of people on the planet. The future of mankind depends to no little degree on the outcome of this ideological struggle. Finally, the importance of the Plenum of the Central Committee of the CPSU also lay in the fact that it posed a whole series of extremely important practical tasks in the area of ideological activity, including scientific activity, and the task of intensifying the influence of ideology on solving economic, social, political, and educational problems.

A function is recursive (in given operations) if its values are computed explicitly and uniformly in terms of other "previously computed" values of itself and (perhaps) other "simultaneously computed" recursive functions. Here, "explicitly" includes definition by cases. We investigate those recursive functions on the structure $\mathbf{N} = \langle \omega, 0, \operatorname{succ,pred}\rangle$ that are computed in terms of themselves only, without other simultaneously computed recursive functions.

The humanitarian thought did not encounter such challenges that we face today. Biotechnologies outline the perspectives of “posthuman” personology, while digitalization and robotization of almost all spheres of social practice bring to the fore the idea of homodicy – justifying the need for human existence. The article analyzes four blocks of challenges to humanitarian knowledge: (1) achievements in medicine, prosthetics, transplantology and genetic engineering, which outlined the separation of a sentient subject from traditional anthropomorphism (“posthuman” personology); (2) studies of the (...) brain neurophysiology, which advanced new arguments against free will; (3) costs of ill-considered propaganda of human rights; (4) digitization of almost all socio-cultural practices – from economics and military affairs to the formation and functioning of authority. Digitalization permeates all these “problematization fields,” setting their common conceptual and technological platform. In this regard, the question arises of the humanitarian expertise of modern technologies and the projects of education, communication and management, which implemented with their help. That expertise deals with not only the consequences, progress or even the possibility of implementing such projects, but also with their necessity. The focus and criteria of such expertise are important. Obviously, it cannot be directed only at the preservation of the biological species of homo sapiens and the conditions of its survival. Paradoxical choice arises in a situation where freedom and free will are questioned: which is more important – homo or sapiens? It is time for a clear distinction between the concepts of humanism and humanitarianism, including in the latter the posthuman personology. If humanitarianism is a personology of free spirit, then humanism seems to have a place next to economism and nationalism as forms of confined humanitarianism. This wide range of problems requires comprehension not only of their content but also of the methodology of the humanities and of the prospects of the humanities in modern society. (shrink)

Celebrated and castigated as the “Hobbes of the twentieth century” and even a modern Machiavelli. Carl Schmitt (1888–1984) is undoubtedly the most controversial legal and political theorist of the twentieth century. He greatly influenced the thinking of such political scientists and political philosophers as Hans J. Morgenthau, Franz Neumann, Otto Kirchheimer, Leo Strauss, and Julien Freund. But Schmitt always spoke and wrote as a jurist. He grounded his thinking in jurisprudence and was the teacher in the wider sense of such (...) jurists as Ernst‐Wolfgang Böckenförde and Ernst‐Rudolf Huber. (shrink)

Even a decade after the end of the 1914–1918 war, economic theory assumed that the world was tranquil and orderly. By 1939 an economic slump without parallel, allied to the re-emergence of military ambition in Europe, had brought economic theorists face to face with reality. In this classic book, first published in 1967, Professor Shackle provides a study, in exact and professional language, of the precise nature, structure, presuppositions, language and inter-relations of the theories which were formulated in these fourteen (...) years - unparalleled in the whole history of economics except perhaps by the years of the Physiocrats and Adam Smith. These theories are not prototypes on the way to something better but are of essential and permanent importance. (shrink)

Don Carlos de Sigüenza y sor Juana Inés de la Cruz no solo se encuentran en la encrucijada del paso de la edad media a la moderna, y del viejo al nuevo mundo, sino de la vieja a la nueva vía de reflexión y de la vieja a la nueva ciencia. Es lo que se intenta mostrar en estas páginas.
