With viewership of NFL (National Football League) football in the US rising above 20 million, interest in the NFL Draft has also been at all-time highs in recent years. Much of this interest is directed toward the “NFL draftniks” who provide draft predictions—so-called “mock drafts”—leading up to the NFL Draft. Despite increasing interest in “NFL draftnikology,” the scoring methodology used to evaluate mock NFL drafts lags far behind. This study offers a few alternative approaches, including a Euclidean metrics approach to evaluating mock NFL drafts. The usefulness of our methodologies extends to evaluation of economic and financial analysts. 相似文献

Considerable attention has been devoted in recent years to theuse of political drama by the president, with the most discretionaryforms of drama—speeches and foreign travel—receivingmuch scrutiny. In fact, there has arisen a conventional wisdomwhich asserts that televised speeches and foreign travel bythe president (1) have increased over time, (2) exert a uniformlypositive impact on public evaluations of the president's performance,and (3) can therefore be used as a strategy for influencingthe president's approval ratings, a vital resource for the modernpresident. The purpose of this paper is to evaluate this conventionalwisdom and thus assess the value of televised speeches and foreigntravel as influences on presidential approval. The paper firstdefines political drama and casts the conventional wisdom inthe form of three propositions. It next develops a researchstrategy for evaluating these propositions in an appropriatemanner. Finally, the paper tests the propositions. The resultscast considerable doubt on the conventional wisdom and leadto the conclusion that the use of political drama is not anall-purpose strategy guaranteed to halt declines or replenishsizable losses of presidential approval. 相似文献

A comparison of response rates and patterns to a mail surveyconducted simultaneously on random samples drawn from telephonelistings in Seattle, Washington, and Kobe, Japan, is presented.When undeliverable surveys (those for which the intended respondenthad moved or passed away) are subtracted from the original samples,a comparison of the differences in the response rate percentagesfor the two countries is found to be statistically insignificant.Adherence to the theoretical foundation of the Total DesignMethod is claimed to be the principal reason for success inachieving a higher response rate than predicted by Japanesescholars to the mail survey in Japan. These results show thatthere is potential for adapting survey research techniques developedin the United States to non-Occidental settings. 相似文献

Comparing products using data envelopment analysis 总被引:3,自引:0,他引:3
Using an application of linear programming known as Data Envelopment Analysis (DEA), a method is described to compare products which vary in excellence along a number of dimensions, and for each of which there might be a number of associated “costs”. The method is illustrated by comparing published benchmarks of 37 computer printers. Potential uses of a DEA analysis of products might be: to assist corporate buyers who may need to reconcile a diversity of present and future uses in one standardised purchase; in competitor analysis; in determining unexplored market niches; and as a normative model of product excellence against which product purchasing behaviour could be compared. 相似文献

PURCHASING POWER PARITY AND BLACK-MARKET EXCHANGE RATES 总被引:1,自引:0,他引:1
WILLIAM PATTON CULBERTSON JR. 《Economic inquiry》1975,13(2):287-296
This paper develops a theory of black-market exchange rate determination as a function of the market-clearing rate, the official rate and changes in official reserve levels. The model is tested for three countries over the period 1952–1971 by using purchasing-power-parity calculations as approximations of the equilibrium rate. The results indicate that relative rates of inflation are the dominant forces influencing equilibrium exchange rates. 相似文献
