1. Our chief reason for suspecting the existence of a connexion between the state of the solar surface (as this is revealed by spots) and the magnetism and meteorology of the earth is derived from the fact that our observational series of sun-spots, on the one hand, and of magnetical and meteorological changes, on the other, are believed to be all subject to a common inequality, whose period (about 11 years) is virtually the same in all.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

In the introduction to his great work of 2005, Framing the Early Middle Ages, Chris Wickham urged not only the necessity of carefully framing our studies at the outset but also the importance of closely defining the words and concepts that we employ, the avoidance ‘cultural sollipsism’ wherever possible and the need to pay particular attention to continuities and discontinuities. Chris has, of course, followed these precepts on a vast scale. My aim in this chapter is a modest one. I aim to review the framing of thirteenth-century England in terms of two only of Chris’s themes: the aristocracy and the state—and even then primarily in terms of the relationship between the two. By the thirteenth century I mean a long thirteenth century stretching from the period of the Angevin reforms of the later twelfth century on the one hand to the early to mid-fourteenth on the other; the reasons for taking this span will, I hope, become clearer during the course of the chapter, but few would doubt that it has a validity.

AbstractQuite a few recent ECJ judgments touch on various elements of territorial rule. Thereby, they raise the profile of the main question this Article asks: Which territorial claims does the EU make? To provide an answer, the present Article discusses and categorizes the individual elements of territoriality in the EU’s architecture. The influence of EU law on national territorial rule on the one hand and the emergence of territorial governance elements at the European level on the other provide the main pillars of the inquiry. Once combined, these features not only help to improve our understanding of the EU’s distinctly supranational conception of territoriality. What is more, the discussion raises several important legitimacy questions. As a consequence, the Article calls for the development of a theoretical model to evaluate and justify territoriality in a political community beyond the state.

Abstract This article argues that international law and the literature of civil war, specifically the narratives from the Philippine communist insurgency, present two visions of the child. On the one hand, international law constructs a child that is individual and vulnerable, a victim of violence trapped between the contending parties. Hence, the child is a person who needs to be insulated from the brutality of the civil war. On the other hand, the article reads Filipino writer Kris Montañez’s stories as revolutionary tales that present a rational child, a literary resolution of the dilemmas of a minor’s participation in the world’s longest-running communist insurgency. Indeed, the short narratives collected in Kabanbanuagan (Youth) reveal a tension between a minor’s right to resist in the context of the people’s war and the juridical right to be insulated from the violence. As their youthful bodies are thrown into the world of the state of exception, violence forces children to make the choice of active participation in the hostilities by symbolically and literally assuming the roles played by their elders in the narrative. The article concludes that while this narrative resolution appears to offer a realistic representation and closure, what it proffers is actually a utopian vision that is in tension with international law’s own utopian vision of children. Thus, international law and the stories of youth in Kabanbanuagan provide a powerful critique of each other’s utopian visions.

Abstract. This paper provides an analysis of the combined theory of gravity-inertial-Rossby waves on a β-plane in the Boussinesq approximation. The wave equation for the system is fifth order in space and time and demonstrates how gravity-inertial waves on the one hand are coupled to Rossby waves on the other through the combined effects of β, the stratification characterized by the Väisälä-Brunt frequency N, the Coriolis frequency f at a given latitude, and vertical propagation which permits buoyancy modes to interact with westward propagating Rossby waves. The corresponding dispersion equation shows that the frequency of a westward propagating gravity-inertial wave is reduced by the coupling, whereas the frequency of a Rossby wave is increased. If the coupling is sufficiently strong these two modes coalesce giving rise to an instability. The instability condition translates into a curve of critical latitude Θc versus effective equatorial rotational Mach number M, with the region below this curve exhibiting instability. "Supersonic" fast rotators are unstable in a narrow band of latitudes around the equator. For example Θc~12° for Jupiter. On the other hand slow "subsonic" rotators (e.g. Mercury, Venus and the Sun's Corona) are unstable at all latitudes except very close to the poles where the β effect vanishes. "Transonic" rotators, such as the Earth and Mars, exhibit instability within latitudes of 34° and 39°, respectively, around the Equator. Similar results pertain to Oceans. In the case of an Earth's Ocean of depth 4km say, purely westward propagating waves are unstable up to 26° about the Equator. The nonlinear evolution of this instability which feeds off rotational energy and gravitational buoyancy may play an important role in atmospheric dynamics.

And so Missouri has fallen, that great State! Certain of her children have joined the lynchers, and the smirch is upon the rest of us. That handful of her children have given us a character and labeled us with a name; and to the dwellers in the four quarters of the earth we are “lynchers,” now, and ever shall be. For the world will not stop and think – it never does, it is not its way; its way is to generalize from a single sample. It will not say “Those Missourians have been busy eighty years in building an honorable good name for themselves; these hundred lynchers down in the corner of the State are not real Missourians, they are bastards.” No, that truth will not enter its mind; it will generalize from the one or two misleading samples and say “The Missourians are lynchers.” It has no reflection, no logic, no sense of proportion. With it, figures go for nothing; to it, figures reveal nothing, it cannot reason upon them rationally; it is Brother J. J. infinitely multiplied; it would say, with him, that China is being swiftly and surely Christianized, since 9 Chinese Christians are being made every day; and it would fail, with him, to notice that the fact that 33,000 pagans are born there every day, damages the argument. It would J-J Missouri, and say “There are a hundred lynchers there, therefore the Missourians are lynchers;” the considerable fact that there are two and a half million Missourians who are not lynchers would not affect their verdict any more than it would affect Bro. J. J.'s.

The Aviation Group of the Ministry of Technology (formerly the Ministry of Aviation) is responsible for spending a large part of the country's defence budget, both in research and development on the one hand and production or procurement on the other. In addition, it has responsibilities in many non-defence fields, mainly, but not exclusively, in aerospace.Few developments have been carried out entirely within the Ministry's own Establishments; almost all have required continuous co-operation between the Ministry and Industry. In the past the methods of management and collaboration and the relative responsibilities of the Ministry and Industry have varied with time, with the type of equipment to be developed, with the size of the development project and so on. But over the past ten years there has been a growing awareness of the need to put some system into the complex business of translating a requirement into a specification and a specification into a product within reasonable bounds of time and cost.

Philosophers of earlier ages have usually spent time in considering thenature of marital, and in general familial, duty. Paley devotes an entire book to those ‘relative duties which result from the constitution of the sexes’,1 a book notable on the one hand for its humanity and on the other for Paley‘s strange refusal to acknowledge that the evils for which he condemns any breach of pure monogamy are in large part the result of the fact that such breaches are generally condemned. In a society where an unmarried mother is ruined no decent male should put a woman in such danger: but why precisely should social feeling be so severe? Marriage, the monogamist would say, must be defended at all costs, for it is a centrally important institution of our society. Political community was, in the past, understood as emerging from or imposed upon families, or similar associations. The struggle to establish the state was a struggle against families, clans and clubs; the state, once established, rested upon the social institutions to which it gave legal backing.

According to Aristotle all heavenly movement is ultimately due to the activity of forty-seven (or fifty-five) ‘unmoved movers'. This doctrine is highly remarkable in itself and has exercised an enormous historical influence. It forms part of a world-picture the outlines of which are as follows. The universe consists of concentric spheres, revolving in circles. The outermost of these bears the fixed stars. The other either bear planets or, insofar as they do not, contribute indirectly to the movements of the latter. Each sphere is moved by the one immediately surrounding it, but also possesses a movement of its own, due to its mover, an unmoved, incorporeal being. (It was these beings which the schoolmen designated as theintelligentiae separatae.) The seemingly irregular movements of the planets are thus viewed as resulting from the combination of regular circular revolutions. The earth does not move and occupies the centre of the universe. Such was Aristotle's astronomic system, essential parts of which were almost universally adopted by the Arabic, Jewish, and Christian philosophers of the Middle Ages.

In first chapters of this article MacIntyre?s view of ethics is analyzed, together with his critics of liberalism as philosophical and political theory, as well as dominant ideological conception. In last chapters MacIntyre?s view of the relation between politics and ethics is considered, along with the critical review of his theoretical positions. Macintyre?s conception is regarded on the one hand as very broad, because the entire morality is identified with ethical life, while on the other hand it is regarded as too narrow since it excludes certain essential aspects of deliberation which refers to the sphere of individual rights, the relations between communities, as well as distribution of goods within the state.
