The productive efficiency of a firm can be seen as composed of two parts, one persistent and one transient. The received empirical literature on the measurement of productive efficiency has paid relatively little attention to the difference between these two components. Ahn, Good and Sickles (2000) suggested some approaches that pointed in this direction. The possibility was also raised in Gree...

Iron agricultural tools from the Revne agglomeration of Slavs 8th—10th centuries is analyzed in paper. The complex one outstanding sites Eastern Croats Slavic tribal group Ukrainian Carpathian region (fig. 1). During ca. 50 years stationary and supervisory explorations almost complete set for primary secondary tillage harvesting has been accumulated.

THE HIGH PREVALENCE OF BREAST cancer survivors is due to general gains in life expectancy and to improved survival in women with a personal history of breast cancer (PHBC), attributable to improvements in local and systemic treatments and early detection. Women with PHBC are at risk of developing second breast cancers, which can be ipsilateral (in-breast recurrence or new ipsilateral cancer) or...

We propose a probability-integral-transformation-based estimator of multivariate densities. Given a sample of random vectors, we first transform the data into their corresponding marginal distributions. We then estimate the density of the transformed data via the Exponential Series Estimator in Wu (2010). The density of the original data is then estimated as the product of the density of the tr...

The microtubule (MT) motor protein kinesin is a vital component of cells and organs expressing acrylamide (ACR) toxicity. As a mechanism of its potential carcinogenicity, we determined whether kinesins involved in cell division are inhibited by ACR similar to neuronal kinesin [Sickles, D.W., Brady, S.T., Testino, A.R., Friedman, M.A., and Wrenn, R.A. (1996). Direct effect of the neurotoxicant a...

Previous research on male subjects has conjectured that subjective selfreports of health status may lead to an upward bias in the estimated effect of health on labor force participation because subjects who are out of the labor force may be more likely to understate their health status so as to justify their lack of employment. In the descriptive analysis conducted in this article, we compare t...

The article sums up the results of archaeological investigations settlements South Volyn (the territory around annalistic Danyliv town) and Western Podillia sites complex Zbruch cultural center, Terebovlia). Authors conducted generalization findings agriculture implements, white straw crops remains supplemented source base. During fortified at end 20th — beginning 21th centuries scientists disc...

Power-law distributions have a wide range of applications including physics, economics, and biology. We derive a new family of densities with support on the real line which obeys a broken power law called the volcano distribution. An estimation procedure is also outlined. The volcano density is very flexible as it can be unbounded or bimodal. It allows for an infinite mean or an undefined mean....

We consider the bootstrap method for the covariates augmented DickeyFuller (CADF) unit root test suggested in Hansen (1995) which uses related variables to improve the power of univariate unit root tests. It is shown that there are substantial power gains from including correlated covariates. The limit distribution of the CADF test, however, depends on the nuisance parameter that represents the...
