T | HE 'Chandos clause' in the i832 Reform Act, which contemporaries believed delivered up the counties to Tory electoral domination, still has its place in the history books. Its author, Richard Plantagenet TempleNugent-Brydges-Chandos-Grenville, second Duke of Buckingham and Chandos, has virtually none. This is a pity, not because his political career is especially significant, although the activities of the Farmers' Friend particularly in influencing and organizing other Members of Parliament might repay investigation; but because his financial affairs are of exceptional interest. In his own time he earned wide notoriety through spectacular financial ruin and utter collapse, culminating in the sale of most of his landed property and personal effects in the course of I 848. It is something of this renown which deserves to be recaptured. Aristocratic indebtedness has attracted considerable attention from historians of many periods in late years, both because of its importance to the proper understanding of the economy of landownership, and because of its possible effects on aristocratic political and economic policy.' If serious debt was sufficiently widespread to be characteristic of the landed aristocracy as a class, or of a considerable section of it, we would rightly expect to see its influence reflected in the political and economic life of the country. In the nineteenth century, the preservation and enhancement of the value of the land which had to carry these debts would then rank as one of the principal interests at stake in the Corn Law controversy. We would expect to find a social and political revolution caused by extensive land transfers made under the pressure of debt, and failing to detect this would justifiably assume that a successful effort to stave off ruin by increasing incomes from land ought to take its place in any general interpretation of the process of economic growth, as part of the great landowners' contribution to that expansion. Eagerness to reach these realms of general speculation has tended to obscure the difficulties of making the first assumption. An array of impressive figures of debts has been taken as sufficient proof. Debts, however, require careful handling as evidence: they may as easily indicate increasing prosperity as increasing adversity, intelligent use of available resources as wayward misappropriation. It would be as unwise to conclude that all aristocrats were in a precarious situation because all had some debts as to say that all governments or all manufacturers were on the verge of bankruptcy because they had large national debts or operated largely on credit. It is common ground that there were several different sources of debt among the landed families of the eighteenth and nineteenth centuries, not all of which were of equal importance in causing serious financial embarrassment.

The essence of federalism is the division of sovereignty between two levels of government. In any system of government, there are sovereign and delegated authorities. In a unitary government all sovereign powers are concentrated in the central government, although decentralization for the purpose of administrative efficiency may result in the delegation of certain powers from the central and supreme government to the regional and local subordinate authorities. In a federal state, on the other hand, regional governments, as well as the central authority, are invested with sovereign powers. In no actual case, however, do both levels of government enjoy sovereignty in all domains, since complete concurrence of jurisdictions would lead to incessant conflicts of coordinate authorities. For this reason, federal constitutions indicate, in a more or less precise way, the special fields of absolute competence of the central and the regional authorities. Partial concurrence of jurisdictions may not be excluded, in which case the problem of bringing about agreements between the sovereign powers arises. Administrative efficiency in a federal state requires both centralization and decentralization of executive functions, in much the same way as in a unitary state. If subordinate functions are delegated to the regional governments, these governments become subordinate to the central authority in these fields. On the other hand, administrative efficiency may require the centralized administration of certain matters in the realm of provincial supremacy, for example, the collection of provincial taxes. In this case, the central government would act as an agent of the provincial governments, and be subordinate to them. The two types of powers–sovereign and delegated–must be clearly distinguished in order to prevent unnecessary conflicts of authority.

Among the greatest obstacles in the postwar recovery of steel industry in Japan were. counted the shortage of coal, the removal of subvention to the iron and steelprices and -decentralization of large steel firms. A tragic atmosphere thus clouded was pushed away by the breakout of the Korean Incident (June 1950). Again the prices became enhanced. The export was extended and the production increased. Thence came a chance of modernization of iron and steel industry in Japan. The scheme of this plan that had been plotted by the Rationalization Council in the first half of 1951 was encouraged in the second half by establishment of Japan Development Bank, institution of special overeas credit by the Bank of Japan and the favorable development in Capital market.Capital development and production increase of steel firms in Japan was suceessively realized -during the year of 1951. However, towards 1952 the period of reaction began so that an intensification of the sales competition gradually invited a drop in the steel prices, notwith-standing a temporary short boom due to a steel strike in the United States.In April 1952, the industrial control of the Occupation Forces ended and Japan was again allowed to enter an international economic circles.At this moment, owing to establishment of the European Coal and Steel Community, progress of modernization progress in several countries and recovery of the West-Germany iron and steel industry, the steel industry of Japan too was obliged to be entangled with the international contest.In 1953, the steel market again tended to a slight boom due to domestic investment and consumption but at the end of the same year decrease in bath munition demands and steel export again occurred. Without finding domestic demands, the steel products of Japan began to flow out overseas. At this time happily owing to a shortage of steel export from Europe Japanese products filled the markets of South America and India and enjoyed higher prices. It was also evident at the end of 1954 that the iron and steel industry in rapan again inclined to an expansive production.After such historical introduction, the author described in detail (1) the process of rationalization and financing concerned; (2) trends in the situations of raw materials for iron and steel; (3) domestic market and export; (4) some tendencies in special steels; and (5) future prospects.

The applicability to a quantum liquid of the standard classical formula connecting the compressibility with the coherent scattering cross section for large wavelengths, questioned by the author in a previous paper, is examined. The correctness of the standard formula is proved (a) at absolute zero (the density fluctuations being infranormal); (b) under quantum conditions for all temperatures at which the Wigner expansion converges (it is conjectured that for liquid helium the expansion may diverge below the lambdapoint); and (c) for a one-dimensional crystal for all temperatures. These results, while they stop short of a complete proof of the standard classical formula for all conditions, do extend considerably our knowledge of its range of validity.

5 A similar distinction is made in Minnequa Cooperage v. Hendricks, 130 Ark. 264, 197 S.W. 280 (1917), where it was held that a statute providing for a three-fourths verdict'was unconstitutional though the parties "might have agreed that a less number than the whole might render a verdict."6 Various preliminary distinctions can be made at this point: The burdenof proof in criminal cases is greater than in civil cases; in civil cases life or liberty is not at stake and many more opportunities for compromise are present.7204

Book Reviews139 Thaddée Soiron, O. F. M., La condition du théologien, Introduction et adaptation française par Yves Becker et Jean-Robert Hennion, O.F.M. (Coll. Credo, Paris: Librairie Pion, [1953]; 193pp.) This booklet is the first volume of a new collection, pubUshed under the direction of H. I. Marrou, Professor of the Sorbonne, and of the Franciscan A. Hammann. "Credo" wants to publish theological essays for educated Christians of our time, assays showing the connection between our living Faith and the doctrinal (scientific ?) expression of it. A leading principle of the coUection will be the famous "Back to the sources", meaning here the Bible, the Fathers and Liturgy; consequently, history will be emphasized. The Editors intend to include works originally written in foreign languages, but corresponding to their program. A representative of the so-called ,,Verkündigungstheologie", Soiron first pubUshed his work in 1935, under the title „Heilige Theologie". La condition du théologien is an "adaptation", viz. certain passages are dropped (e. g. pages 7—35, and more phrases in the subsequent text), most of the references, which in the German original were printed in the text, are now in footnote, etc. The translations are quite fluent, though not ideal: for instance, in the first chapter the translators were obviously confused by Soiron's speculations about "Ustening" as first requisite of Faith. They confuse the reader by translating "Hören" and "Haltung" by "attention" (cf. p. 46—47 of the French with p. 35—37 of the German edition); the version of "Haltung" is rather "attitude"; "attention" is a possible translation of "Hören", but does not always render the idea of Soiron. Becker and Hennion note that for the translation of biblical texts (of the New Testament) they usually took Le Nouveau Testament of E. Osty. On principle this method is acceptable . In certain instances, however, an other translation better fits the context: e.g. p. 48, Soiron is speculating upon "hearing the word", and, consequently, Rom. X 17 requires the translation "Ainsi la foi vient de ce qu'on entend; et l'on entend, lorsque la parole du Christ est prêchée". The version of Osty (la foi naît de la prédication et la prédication se fait sur l'ordre du Christ) is correct of course, and, perhaps, better renders the idea of St. Paul; but the version we propose corresponds to the letter of both the Greek and the German, and is required by the context of Soiron. We say it regretfully, but we prefer rather to recommend reading the German original of Soiron. Eligius M. Buytaert, O. F. M. Franciscan Institute The Moral Obligation of Voting. By Titus Cranny, S.

The other volume under consideration is a collection of seven compact lectures deUvered by specialists in the field of American and reUgious thought at the Twelfth Annual Round Table Conferences sponsored by the School of Law at the CathoUc University of America. They present a dispassionate appeal to the lawyers and law students to follow the tradition of our former great statesmen who, because they nourished themselves with daily reading of the Scriptures, adhered to commonly held reUgious and moral convictions beyond the scope of positive civil law. In view of the muddled and false concepts on the part of a great many jurists of our generation, regarding Church-State relationship as envisioned in the opening paragraphs of the Declaration of Independence, these essays provide a concise and interesting appUcation of basic truths to the problems of today, especially for lawyers and law students, both CathoUc and nonCatholic . At the same time they point out the task incumbent upon them : to uphold and defend the reUgious inheritance of our nation's statesmen and jurists of past days. There can be no doubt that only in proportion as the lawyer looks beyond the Law, as he participates in Christ's thinking wiU he fuUy grasp the significance of the basic principles set forth in the American Magna Charta of independence. The book is a remarkable symposium, one that should occupy a prominent place on the law student's shelf. It is indeed a noble chaUengeto thejurists of today to look beyond the Law.

This chapter examines the demand for global financial governance in the wake of the massive financial crisis of 2007–9. The global financial meltdown acted as a catalyst for a dramatic boosting of the International Monetary Fund's (IMF) resources and the creation of the Financial Stability Board (FSB), both which took place at the G20 leaders’ second summit in April 2009. These initiatives appeared to signal a heightened demand for global-level institutions in the areas of liquidity provision and financial regulation emerging from the crisis experience. But the limitations of that demand also quickly became clear as these global institutions found themselves working with and alongside strengthened regional, plurilateral and national authorities in complex ways. The result is neither a strengthening nor weakening of the demand for global governance, but rather a change in the content of the demand. A new kind of “cooperative decentralization” in global financial governance is emerging, driven by the preferences of both dominant powers and Southern countries. The first half of the chapter describes this argument in the case of the IMF. While the IMF's funding boost was dramatic, its significance was immediately called into question by the fact that its new money remained unused in 2008–9 partly because of Southern borrowers’ distrust of the institution. In the end, it was US authorities – not the Fund – that played the most important role in providing international liquidity during this period. Demand for the Fund's resources did, however, grow with the outbreak of the euro crisis, but as a way to supplement European regional arrangements. Lingering distrust of the Fund among Southern officials – reinforced by Northern resistance to governance reform – has encouraged them to strengthen and/or build alternative regional and plurilateral financing arrangements that also work either with or alongside the Fund. The second half of the chapter explores the FSB's creation. This development turned out to be less significant than it initially appeared because the institution was given very little formal power. This design feature reflected both Northern and Southern concerns about accepting international constraints on their regulatory policymaking. The crisis and post-crisis experience only reinforced their commitments to regulatory sovereignty by increasing the domestic political salience of regulatory issues and their fiscal implications, and by revealing the failures of international cooperation relating to the management of failing institutions.

The San Francisco Parking Authority was created in 1949. The Authority is responsible for providing off-street parking facilities in the city and county of San Francisco. This article discusses the powers given to the Parking Authority and relates the observation that many more parking facilities are needed in the city center. It notes that decentralization has effected the city of San Francisco's business sales and it discusses the decision to build more underground parking facilities. It describes the financing of this underground parking, mostly by private business, with little or no cost to the taxpayers. The article ends with a discussion of the attack plan.

E VERYONE knows that administration is the maintaining of an organization at an acceptable level of effectiveness. A single head, working co-operatively with the staff members, assigns duties, supervises the performance of them, and evaluates the outcome. In a community, however, and I shall speak of a university frequently as a community, there are a number of organizations performing often identical, sometimes dissimilar, and sometimes inappropriate services to students. That is, specialized functions or services have grown up in separate organizations. This leads to decentralization of administration, with various organizations functioning not as part of a team or as part of a concerted and comprehensive plan, but often independently and quite frequently competitively. Any situation involving decentralization of functions automatically necessitates the establishment of a corrective which we call co-ordination. Co-ordination is, therefore, an administrative means of avoiding friction, duplication, competition, and other undesirable practices among autonomous independent organizations which operate in the same general field of endeavor. It should be noticed that it is only when there is duplication or conflict in the same general field of endeavor that co-ordination is a necessity. Obviously there is no need for co-ordination when two independent, autonomous organizations operate in fields which are unrelated. Co-ordination is an effective means of developing co-operative relationships which bring about a dovetailing of partial and specialized services into a total program or pattern of services. It is also a means of bringing about a desirable degree of coherence within a decentralized system of organizations. Co-ordination is not a static form of administrative structure. It is rather a function and a dynamic process constantly changing because of at least four factors. First, the workers' personalities, interests, understandings, and motivations change from period to period. Second, there are shifts and changes in the community with respect to the demands made upon the organizations in a particular field of endeavor. Third, the needs of individual clients change as they themselves progress from one age period to another, from one economic status to another, from one physiological status to another, and from one psychological status to another. Fourth, in any field of social endeavor the products of research and systematized experiences constantly feed into the professional practices and services, thereby changing the conceptions of the basic nature of the

anew the old problem of administrative control-centralized, or Federal, versus decentralized, or local. In such cooperative programs as public housing, social security, and education, which are financed jointly by Federal and local governments, this problem calls for certain definite and workable adjustments in accordance with our republican form of government. These adjustments are of the utmost importance to Negro citizens because the majority of them still live in the South where they generally do not participate actively in state or local government and, consequently, are usually unable to make effective demand for their full share of the benefits of the program. In order to assure equitable participation in decentralized programs, Negroes have sought both legislative and administrative safeguards. The public resolution appropriating funds for the Work Projects Administration for the fiscal year ending June 30, 1940, forbids racial discrimination in employment. Efforts have been made to have similar clauses inserted in legislation appropriating Federal funds for education and health.1

Urban concentralization may signify either the settlement of a large percentage of a nation's population in metropolitan areas or the concentration of the dwellers of any city into a compact mass with high population density per acre. The term is used in this article in both senses. The urban functions that once contributed to urban centralization, namely, (1) centralized governmental power, (2) defense, (3) religion, (4) amusement, (5) trade, (6) industry, (7) transportation, (8) finance and banking, and (9) utilities, are now promoting urban decentralization in the form of the exodus of the residential population from central areas to the periphery of cities. A historical review of urban development shows that the original small nations in the Mediterranean basin were finally merged into the Roman Empire, with the apex of ancient urban civilization at Rome itself. The disintegration of the Roman Empire caused urban decentralization in the sense of the breaking-up of large cities. The small feudal states of the early Middle Ages could support only villages or small towns in Europe. The rise of modern urban communities began with the growth of commerce and the discoveries of the Portuguese and Spanish navigators. England became the first great commercial manufacturing nation and became highly urbanized by the middle of the nineteenth century. The United States and Germany made rapid progress in industrialization and urbanization from 1851 to 1891. The competition between rival industrial-urban nations was one of the chief causes of World War I. After 1920, Russia, Italy, and Japan endeavored to develop self-sufficing industrial-military systems, thereby increasing the population of their great cities but also heightening the tension leading to World War II. The prospects for continued urban centralization in all these powers are not favorable, for the victory of one group of nations will tend to inhibit the growth of urbanism in the defeated states.

Of primary importance to the investor in corporate shares is the dividend return. But many a purchaser of shares has other dominant interests. He may desire merely to qualify to be a director. He may be a pirate and contemplate a particular suit which he can institute only as a shareholder. He may hope to acquire the right of a shareholder to examine the stock ledger or other books or records of the corporation in order to broaden his activities as a broker or promoter. He may seek to gain control of the corporation in order to loot it, or to preclude it from competing with some other enterprise in which he is primarily interested. He may be a speculator buying shares to cover a previous short sale, or in anticipation of a rising market and a profitable resale. No one of these persons has the interest of an investor. The investor buys shares for the long pull, and while he will be gratified by an appreciation in market value, his major concern is with income, i. e. dividends. One investing in corporate shares, whether an individual or an institution, desires the corporation to make the maximum possible profits and to distribute such profits in the form of dividends as rapidly as may be consistent with the continuation of maximum profits in the future. But this may not be the goal of the corporation's management. In many modern corporations the ownership of the shares is so widely scattered that the management, i. e. executive officers and directors, through control of the proxy process for shareholders' meetings, is self-perpetuating.' Where such management control exists, the members of the management may own very few shares, as personal shareholdership is not the basis of their control. And where the officers and directors themselves own very few shares, their interest in the corporation may relate primarily to matters other than the distribution of profits. They may develop philanthropic interests such as raising living standards by increasing wages as rapidly as competitive conditions allow, or by progressively producing more and cheaper units to the benefit of the consuming public. Or they may be interested not in dis-

Of the ten thousand young artists along the Pacific Coast, how many are important? Ten thousand of them are important. No great artist in the past has leapt full fledged from the brain of Zeus. They have all grown out of the endless striving of countless seekers after beauty. And we may expect a few young artists of today along the Pacific to achieve greatness precisely because nine thousand nine hundred and ninety young men and women are staking their all in search of some ultimate perfection.Here and there a sculptured form or painted picture re-creates us as we gaze, and our own refeshment and renewal are proof that we have eaten of the god—the art is authentic. The work of Donal Hord, San Diego sculptor, has this rare greatness. His granite figure of the Aztec, just nearing completion, is already timeless. Here is not the face of a mere American Indian; here is the face of the cosmos. We enter a world beyond good and evil, beyond striving and regretting. Here is equilibrium of spirit and form. The figure is hewn from a two and a half ton block of black diorite, the same hard species of stone in which the sculpture of the Egyptians has come down to us through some six thousand years. The subject of the Aztec was chosen because of its symbolic meaning for the San Diego State College, whose students have commissioned this work as an art heritage for future generations, even down to the class of 6937. (While the inspiration for the work and the purchase of the materials came from the students, the cost of the years of labor that have gone into the sculpture has been carried by the Federal Art Project.) Hord tells us that the nature of the material always determines for him, in a large measure, the form. Agitated lines in this impervious granite would have tortured the sculptor no less than the stone. Moreover, the expressive modelling of the head is the more powerful above the severe planes of the serape drawn about the massive, crouching figure. The pose is not suggested by some ancient sculptor, but by a characteristic of the contemporary Mexican which he may well have inherited from his Aztec forebears. He likes to sit for hours in this position, observing the passing scene, or meditating on the meaning of life.

The possible methods of utilizing magnetrons to generate short-wave oscillations are indicated and the more important results of previous workers are described. The theoretical basis of “electronic”and “dynatron”oscillations is discussed, with particular reference to those features which can be investigated experimentally. It is shown that the wavelength of the electronic oscillations is determined mainly, if not entirely, by the electron time of transit. The general expression for the time of transit is given and hence expressions for the wavelength in terms of magnetic field strength are obtained for zero and saturated space-charge conditions. The wavelength is found to be about 36 per cent greater in the latter case. It is shown that initial electron velocity causes an appreciable reduction in wavelength in normal cases. The effect of magnetic field on space charge is considered and is found to lead to a small, possibly negligible, increase in wavelength. It is shown that the space charge is uniformly distributed when the magnetic field strength exceeds the critical value at which the electron orbits just touch the anode surface. This result has been previously stated by Hull, but Hull's deduction that the electrons travel in circular orbits round the cathode is disputed.An attempt to provide a simplified theoretical explanation of the “dynatron”characteristics of a “split anode”magnetron leads to a false result from which it is concluded that no theory will provide an explanation which does not take into account the non-uniformity of the electric fields in the two halves of the valve. The general shape of the static characteristics is indicated by means of Habann's theory, which is, however, not capable of giving proof of the existence of negative resistance in the case of a symmetrical oscillatory circuit, which is the case considered here. A qualitative explanation of the occurrence of negative resistance, i.e. of the greater fraction of the anode current reaching the lower-potential anode segment, is given.The object of the experimental investigation was to discover the nature of the fundamental relations in the electronic and dynatron types of oscillation, to compare these relations with the indications of the theory, and to apply the knowledge obtained to the production of a sufficient amount of power to be technically useful at the shortest possible wavelength.For electronic oscillations it is found that the experimental results are entirely in agreement with the theory in so far as it is applicable. In particular it is confirmed that the strength of the electronic oscillations is greatest at the “critical” relation between anode voltage and magnetic field strength, and that the wavelength of the optimum oscillation is inversely proportional to the magnetic field strength. The actual value of the wavelength and the amount of the wavelength change due to space charge both agree with the theoretical values within experimental accuracy. It is concluded that the effect of magnetic field on space-charge distribution is not great enough to affect the wavelength appreciably. It is shown that apparently anomalous results can be explained by taking into account the stray capacitances, due in particular to the glasswork of the valve, across the oscillatory circuit. Theselead to internal resonance effects which, although often a nuisance to the investigator, sometimes have the advantage of enabling a relatively large output to be obtained at a particular wavelength.The fact that the greatest output is, in general, obtained with the magnetic field not exactly in the direction of the electrode axis, which has been reported by Slutzkin and Steinberg and by Ranzi, was observed independently. The existence of an optimum field angle differing from zero is found to be due to the resultant spiral motion of the electrons balancing out the effect of cathode potential-drop for electrons arriving at part of the anode surface in such a way as to increase the number of oscillating electrons.By making use of an internal resonance effect and suitably adjusting the field angle,'an output of the order of 1–5 watts was obtained at a wavelength of about 24 cm.It is pointed out that the wavelength of the electronic oscillations can be expressed in the same form as the Bark-hausen-Kurz equation for the triode case, and that the existence of an optimum value of anode current (approximately 1/10th of the space-charge saturation value) leads, as in the triode case, to the result that the minimum wavelength obtainable without overloading the valve depends on the anode diameter and decreases with it. For an anode diameter of 3 mm the shortest wavelength at which optimum oscillating conditions can be maintained is of the order of 20 cm. The corresponding figure for the triode case (grid diameter 3 mm) is about 50 cm. The shortest wavelength actually observed was 18 cm. Oscillations of shorter wavelength have not been investigated, owing to the small power obtainable.It is shown that it is possible to obtain dynatron oscillations in a split-anode magnetron by tilting the magnetic field, and that these are distinct from both the electronic and simple dynatron oscillations. Hollmann has investigated the occurrence of oscillations of this kind in the full cylindrical, anode magnetron and found a minimum wavelength of about 20 m. It is shown here that these oscillations can be produced down to about 35 cm wavelength, but at this wavelength the effect of electron inertia is important.In the investigation of the simple dynatron oscillations, static characteristics showing the negative resistance effect are obtained. From these curves the operating characteristics of the valve are calculated and checked by comparison with a. set of measured values (for a relatively low frequency). Good agreement is obtained.It is found that the energy of the dynatron oscillation starts to fall off rapidly at a wavelength which is about 4 times the electronic oscillation wavelength corresponding to the anode voltage used. This leads to a formula for the wavelength limit for dynatron oscillations.The relation between oscillation amplitude and anode voltage is discussed, with particular reference to modulation.It is found that during oscillation the anode current may exceed the original total emission. This is probably due to bombardment of the filament by electrons which return to it with considerable velocity. The exact mechanism of this bombardment is not clear and the effect is being further investigated. By taking steps to reduce this effect it has been possible to obtain an output of 60 watts from a relatively small valve at about 2 m wavelength.The shortest wavelength obtained by means of dynatron oscillations was about 30 cm. At this wavelength the power obtainable was about 0-1 watt. It is concluded that for wavelengths below about 50 cm electronic oscillations give the greater output.
