Reduction of tilt rotor download using circulation control
The effect of boundary layer control blowing on the download of a wing in the wake of a hovering rotor was measured in a small scale experiment. The objective was to evaluate the potential of boundary layer control blowing for reducing tilt rotor download. Variations were made in rotor thrust coefficient, blowing pressure ratio, and blowing slot height. The effect of these parameter variations on the wing download and wing surface pressures is presented. The boundary layer control blowing caused reductions in the wing download of 25 to 55 percent
Funding and Asset Allocation in Corporate Pension Plans: An Empirical Investigation
This paper contrasts and empirically tests two different views of corporate pension policy: the traditional view that pension funds are managed without regard to either corporate financial policy or the interests of the corporation and its shareholders, and the corporate financial perspective represented by the recent theoretical work of Black (1980), Sharpe (1916),Tepper (1981), and Treynor (1971), which stresses the potential effects of a firm's financial condition on its pension funding and asset allocation decisions. We find several pieces of evidence supporting the corporate financial perspective. First, we find that there is a significant inverse relationship between firms' profitability and the discount rates they choose tor eport their pension liabilities. In view of this we adjust all reported pension liabilities to a common discount rate assumption. We then find a significant positive relationship between firm profitability and the degree ofpension funding, as is consistent with the corporate financial perspective. We also find some evidence that firms facing higher risk and lower tax liabilities are less inclined to fully fund their pension plans. On the asset allocation question, we find that the distribution of plan assets invested in bonds is bi-modal, but that it does not tend to cluster around extreme portfolio configurations to the extent predicted by the corporate financial perspective. We also find that the percentage of plan assets invested in bonds in negatively related to both total size of plan and the proportion of unfunded liabilities.The latter relationship shows up particularly among the riskiest firms and is consistent with the corporate financial perspective on pension decisions.

Legislative Trends in the Delegation of School Powers in Texas
The delegation of powers by the Legislature in carrying out school laws has always been a function of that body. In 1929 Justice Walker, in the case of Richardson v. Liberty Independent School District, stated that all powers possessed by school districts have been delegated by the Legislature. The same is true in respect to the powers possessed by the State Board of Education and the county boards of education. All these divisions have been created by law and all their powers delegated by the Legislature.By this study the writer will try to show what trend the Legislature has taken in the delegation of powers concerning,schools. In this study the solution of the following questions will be sought: 1. Is there a tendency toward more delegation of power to the state level of administration? 2. Is there a tendency in the Legislature to give more power to county and local units in the school system? 3. Is the Legislature inclining toward exercising more power on its own initiative? By the study of laws passed by the Legislature delegating powers and retaining powers, these problems can be answered and a definite trend shown
