Research on the tendency of governments to trade off welfare spending for defense has generated diverse and often contradictory findings. This study attempts to clarify the issue of trade-offs by examining expenditure patterns since 1948 for the four major NA TO allies: United States, United Kingdom, Federal Republic of Germany, and France. When viewed from the perspective of long-term trends in shares of outlays, trade-offs are evident. When short-term changes in expenditure, which are more germane to the potential for one spending category to benefit at the expense of the other are studied, no pattern of trade-off can be detected. A three-equation model is estimated to control for the variety of possible determining factors of public resource allocation. In none of the four nations does a pattern of trade-off emerge, except in periods of wartime or postwar reconstruction. These findings are consistent with the ability of governments to finance new spending through either increased taxes or larger budget deficits. The growing disinclination to use these methods, however, suggests that the potential for trade-offs has perhaps reappeared in the 1980s.

The political capacity of advanced societies is measured. We show that politically capable governments can mobilize vast resources from the society under the stress of war, but totalitarian, democratic and authoritarian regimes do not determine the level of performance. The absolute political capacity of rich nations is higher than that of poorer ones, but surprisingly, poor nations can increase their political capacity more effectively under stress. Finally, Power, constructed by combining total resources with the political capacity of governments, is used to postdict accurately the outcome of major wars since 1900.

The defense budget poses many problems to the student of budgetary behavior and its ever-changing structure makes it difficult to identify patterns and trends in allocation. This study examines defense budget requests from the Eisenhower through the Reagan administrations. An analysis of changes in allocation to the 54 appropriation categories suggests that the defense budget responds to new doctrines and management introduced by each administration. Shifts in allocation among the services are greatest in the first two budgets of an administration and reversals of previous program priorities also occur early in each administration. After three or four budget requests, year-to-year continuity in allocation to "winners" and "losers" finally begins to emerge. Two other findings also shed light on the politics of defense budgeting. First, the degree of variation in allocation is least when the defense budget increase is large. Second, low presidential popularity leads to less variation. The identification of such trends should permit future budget requests to be evaluated in the context of the long-term evolution of defense politics.The United States defense budget presents several special problems for the student of budgeting. No other organization consists of four so very competitive, parochial, yet overlapping personnel services with frequently redundant tasks (for a short organizational history see Jones, 1982). In most respects, it would be difficult to identify a functionally integral department among this constellation of organizations were it not for the annual budget process that unifies the civilian and military agencies into a single federal department. It might be recalled that in 1947 its creators first named it the National Military Establishment, a title befitting such a loose alliance of actors in search of the ambiguous goal of"security." Since then, much has been done to reform and coordinate actions (the name was changed after two years), but, in the end, the 0032-2687/84/$03.00 9 1984 Elsevier Science Publishers B.V.

Purpose. Female runners are known to be at greater risk from chronic running injuries than age-matched males, although the exact mechanisms are often poorly understood. The aim of the current investigation was to determine if female recreational runners exhibit distinct limb and joint stiffness characteristics in relation to their male counterparts. Methods. Fourteen male and fourteen female runners ran over a force platform at 4.0 m · s -1 . Lower limb kinematics were collected using an eight-camera optoelectric motion capture system operating at 250 Hz. Measures of limb and joint stiffness were calculated as a function of limb length and joint moments divided by the extent of limb and joint excursion. All stiffness and joint moment parameters were normalized to body mass. Sex differences in normalized limb and knee and ankle joint stiffness were examined statistically using independent samples t tests. Results. The results indicate that normalized limb (male = 0.18 ± 0.07, female = 0.37 ± 0.10 kN · kg · m -1 ) and knee stiffness (male = 5.59 ± 2.02, female = 7.34 ± 1.78 Nm · kg · rad -1 ) were significantly greater in female runners. Conclusions. On the basis that normalized knee and limb stiffness were shown to be significantly greater in female runners, the findings from the current investigation may provide further insight into the aetiology of the distinct injury patterns observed between sexes.
