Adhesives for Aerospace
The industry is hereby challenged to integrate adhesive technology with the total structure requirements in light of today's drive into automation/mechanization. The state of the art of adhesive technology is fairly well meeting the needs of the structural designers, the processing engineer, and the inspector, each on an individual basis. The total integration of these needs into the factory of the future is the next collective hurdle to be achieved. Improved processing parameters to fit the needs of automation/mechanization will necessitate some changes in the adhesive forms, formulations, and chemistries. Adhesives have, for the most part, kept up with the needs of the aerospace industry, normally leading the rest of the industry in developments. The wants of the aerospace industry still present a challenge to encompass all elements, achieving a totally integrated joined and sealed structural system. Better toughness with hot-wet strength improvements is desired. Lower cure temperatures, longer out times, and improved corrosion inhibition are desired
The FOMC: preferences, voting, and consensus
In this paper, the author develops and uses an original dataset collected from the internal discussion of the Federal Reserve's monetary policy committee (the Federal Open Market Committee [FOMC] transcripts) to examine questions about the Committee's behavior. The data show that Chairman Alan Greenspan's proposals, after Committee discussion, were nearly always adopted unmodified in the formal vote. Despite the external appearance of consensus with little disagreement over decisions and an official dissent rate of 7.5 percent, the data reveal that the rate of disagreement in internal Committee discussions was quite high-on the order of 30 percent for discussions of the short-term interest rate. And, under the assumption that FOMC voters assigned a higher priority to their preferences for the short-term interest rate than for the bias in the policy directive, it can be shown that this bias was important for achieving consensus, which supports and extends the results of Thornton and Wheelock (2000). Thus, the novel dataset described in this paper helps to shed some light on the internal workings of the FOMC in the Greenspan years.Federal Open Market Committee ; Monetary policy
Regional influences on U.S. monetary policy: some implications for Europe
This paper looks at the monetary policy decisions of the U.S. Federal Reserve and asks whether those decisions have been influenced solely by national concerns, or whether regional factors have played a role. All of the Federal Reserve''s policymakers have some regional identity, i.e., either their positions explicitly carry some regional affiliation or their region of origin is a factor that must be considered in the selection process. This research is relevant for the Fed, and it may also be relevant for Europe''s fledgling central bank in Frankfurt. Critics have asserted that ECB policymakers have an incentive to base policy on national developments and respond to national political pressures. We find that Fed policymakers do take into account developments in regional unemployment when deciding monetary policy, and that these regional developments are more important for central bankers at the hub than in the spokes. These findings are robust to a variety of different specifications of the voting equation
Publicity of Debate and the Incentive to Dissent: Evidence from the US Federal Reserve
When central banks are transparent about their decision making, there may be clear benefits in terms ofcredibility, policy effectiveness, and improved democratic accountability. While recent literature has focusedon all of these advantages of transparency, in this paper we consider one potential cost: the possibility thatpublishing detailed records of deliberations will make members of a monetary policy committee more reluctantto offer dissenting opinions. Drawing on the recent literature on expert advisors with ¿career concerns¿, weconstruct a model that compares incentives for members of a monetary policy committee to voice dissent whendeliberations occur in public, and when they occur in private. We then test the implications of the model usingan original dataset based on deliberations of the Federal Reserve¿s Federal Open Market Committee, askingwhether the FOMC¿s decision in 1993 to begin releasing full transcripts of its meetings has altered incentivesfor participants to voice dissenting opinions. We find this to be the case with regard to both opinions on shortterminterest rates and on the ¿bias¿ for future policy.transparency, central banking, career concerns
Design, analysis, and fabrication of the technology integration box beam
Numerous design concepts, materials, and manufacturing methods were investigated analytically and empirically for the covers and spars of a transport wing box. This information was applied to the design, analysis, and fabrication of a full-scale section of a transport wing box. A blade-stiffened design was selected for the upper and lower covers of the box. These covers have been constructed using three styles of AS4/974 prepreg fabrics. The front and rear T-stiffened channel spars were filament wound using AS4/1806 towpreg. Covers, ribs, and spars were assembled using mechanical fasteners. When they are completed later this year, the tests on the technology integration box beam will demonstrate the structural integrity of an advanced composite wing design which is 25 percent lighter than the metal baseline
Home Bias, Transactions Costs, and Prospects for the Euro: A More Detailed Analysis
This paper brings together the literature on determination of home bias in equity holdings and the portfolio balance model of exchange rates to consider whether the dollar might be affected by a change in transactions costs that alters international portfolio allocations. Our empirical findings lend support to the view that transactions costs have a significant influence on US portfolio holdings, even after accounting for float market share. In addition, new survey evidence on the equity holdings of European firms indicates home bias for European investors, and points to a reduction in the magnitude of this home bias since 1997.portfolio choice, equity flows, exchange rates
