The Subject

In a short paper publihsed in the Trans. Kans. Acad. Sci., Vol. XIII., on the occurrence, in a single restirced locality in Arizona, of a species of Micropeza, I gave a very brief resumé of the food-habits of some of the better known families of Acalyptrate, Muscidæ, with the view of suggesting the possible habit of the species there considered. This prompted me later to bring together all avialble notes on the subject. As these small flies are of much economic importance, both as being injurious and benefical, I have left that a quite compelte summary of their larval food-habits would be of much use to the working entomologist, besides being of no little importance to those who may be making a special study of the diptera.

The Subject

By tradition public administration is regarded as a division of political science. Woodrow Wilson set the stage for this concept in his original essay identifying public administration as a subject worthy of special study, and spokesmen for both political science and public administration have accepted it since. Thus Leonard White, in his 1930 article on the subject in the Encyclopedia of the Social Sciences, recognizes public administration as “a branch of the field of political science.” Luther Gulick follows suit, observing in 1937 that “Public administration is thus a division of political science ….” So generally has this word got around that it has come to the notice of the sociologists, as is indicated in a 1950 report of the Russell Sage Foundation which refers to “political science, including public administration….” “Pure” political scientists and political scientists with a public administration slant therefore are not alone in accepting this doctrine, which obviously enjoys a wide and authoritative currency.But if public administration is reckoned generally to be a child of political science, it is in some respects a strange and unnatural child; for there is a feeling among political scientists, substantial still if mayhap not so widespread as formerly, that academicians who profess public administration spend their time fooling with trifles. It was a sad day when the first professor of political science learned what a manhole cover is! On their part, those who work in public administration are likely to find themselves vaguely resentful of the lack of cordiality in the house of their youth.

The Community and the Aggressive Child

The Subject

A subject such as this is much too large to deal with at all fully in a short paper. As it is designed as a preparatory review of this topic as it applies to Great Britain, the subject being dealt with at the International Congress of Mental Health by delegates from overseas, I am placing the emphasis on the community rather than on the aggressive child. It is necessary, however, to consider what the aggressive child does to the community and why, in addition to discussing what the community does to the aggressive child, and the reason for this.

Problems for the architect and town planner caused by air in motion

The Subject

This short paper makes no original contribution to knowledge but simply describes and identifies a range of problems encountered in practice by town planners and architects. The term ‘ architectural ’ in the subject title of the Discussion Meeting is taken to imply that the results of aerodynamic research are now as applicable to architectural as to engineering problems. Architecture is broadly interpreted as the coordination of many techniques to give significant form to social programmes. As this is a comprehensive activity, it follows that the problems caused by air in motion range from the location and layout of whole cities at one end of the scale, to the design of a window or the control of an ornamental jet of water at the other. In the middle of this range typical problems arise from the siting of buildings singly and in groups, and in the structure and cladding of high-rise and low-rise buildings to resist wind, rain penetration and air-borne pollution.

Prototype Testing

The title of Prototype Testing is taken here to refer to the flight tests carried out on a new aircraft by its constructor. It embraces a wide field of subjects and in a short paper, it cannot be covered in any way comprehensively. I propose therefore to deal mainly with very general aspects of the subject.The paper does not attempt to embrace out of the ordinary types with special problems peculiar to themselves—an extreme example of which is probably the Brabazon I. Most of my experience on this subject has been concerned with small aircraft, many of them single-seaters, and consequently some of my statements may apply more particularly to this type of aircraft, although many will probably apply equally to other types of aircraft.

The Subject

Abstract This review aims to present advances in studies on the propagation of the Annonaceae species, which includes species of economic importance such as: soursop, custard apple, atemoya and cherimoya. In sexual propagation, advances are mainly related to a better understanding of the stages of seed development, dormancy mechanisms, and germination. In asexual propagation, compatibility studies between grafts and rootstocks are presented, focusing on the expression of genes involved in tissue formation. The cutting method is also discussed, which is another option for the propagation for this group of plants considered difficult to root, approaching endogenous and exogenous factors related to the subject, as well as management strategies that affect the success of this technique.

The Subject

The Observatory of Infante D. Luiz has possessed since 1863 a set of magnetographs giving continuous records similar to those at Kew. In 1870 the results of the declination magnetograph, from the year 1864 to 1867, were published; and in 1874 the results for the same period of the bifilar and balance magnetographs (results embracing the horizontal force, vertical force, total force, and inclination) were published. At present the results of the declination for 1868 to 1871 are in course of publication. The subject of this short paper is the diurnal variations of the disturbances of the declination. The method which has been adopted for reducing the disturbances is that of Sir Edward Sabine. I have taken ± 2 millimetres, or 2'·26, as the limits, beyond which limits all readings are regarded as disturbed.

Relationship Of

With the question of conformity or unconformity between the Lower Tertiary and Upper Cretaceous, there is associated a problem of great economic importance to New Zealand. The subject involves something more than a mere academic discussion. If conformity exists, then we have only one coal-bearing formation; but if unconformity, then we have two. I believe that both the stratigraphical and palæontological evidence is overwhelmingly in favour of the latter.

The Way

I am, naturally, greatly honoured to have been invited by the Royal Institute of Philosophy to organize and conduct their lecture series on American Philosophy. It has been an interesting if trying experience, and I must say that the process of organizing it has given me a special respect for the patience and administrative capacities of those who have the task year in year out. Of course there were special difficulties in the way of importing so many people from the United States (especially since the Institute does not have the funds needed to bring them over), but if the series was to be on American Philosophy—whatever that is—it seemed especially appropriate that the lectures be given predominantly by Americans who have made a special study of the subject— again, whatever that is. We may, of course, end with the conclusion that there is no such distinctive subject, and that the name ‘American Philosophy’ is as nominal as a name can be, but that, we should note, is something to be found out, not a conclusion dictated in advance.
