What implications does a dirty-handed politician‟s assertion that dirty hands are necessary for certain political achievements have on our understanding of the relationship between political actors and the political community? The problem of dirty hands, as described in Michael Walzer‟s “Political Action: The Problem of Dirty Hands,” occurs when a political actor finds that he must transgress o...

There is a growing awareness that high quality of data is a key to today‟s business success and dirty data that exits within data sources is one of the reasons that cause poor data quality. To ensure high quality, enterprises need to have a process, methodologies and resources to monitor and analyze the quality of data, methodologies for preventing and/or detecting and repairing dirty data. How...

We consider the Gaussian Dirty Tape Channel (DTC) YY = XX + SS + ZZ , where SS is an additive Gaussian interference known causally to the transmitter. The general expression mmmmmmPPUU,ff(∙),XX=ff(UU,SS) II(UU;YY) is presented for the capacity of this channel. For linear assignment to ff(∙) , i.e. XX = UU− ββSS , this expression leads to the compensation strategy proposed previously by Willems ...

early detection of free air in the peritoneal cavity is vital in diagnosis of life-threatening emergencies, and can play a significant role in expediting treatment. we present a series of cases in which bedside ultrasound (us) in the emergency department accurately identified evidence of free intra-peritoneal air and echogenic (dirty) free fluid consistent with a surgical final diagnosis of a p...

In this paper, we develop a family of algorithms for optimizing “superpositionstructured” or “dirty” statistical estimators for high-dimensional problems involving the minimization of the sum of a smooth loss function with a hybrid regularization. Most of the current approaches are first-order methods, including proximal gradient or Alternating Direction Method of Multipliers (ADMM). We propose...

Routine "quick-and-dirty" (QD) methods of project appraisal can be so dirty in guiding project selection as to wipe out the net social gains from public investment. A common QD method for estimating benefits from irrigation investments is tested using data for Viet Nam. The results are compared to impacts assessed through econometric modelling of marginal returns that allows for household and a...

This paper investigates how the environmental pollution in East Asian countries can be affected by trade of ‘dirty’ goods with Japan and the USA. By controlling for trade openness, the share of manufacturing in GDP, and the trade of pollution-intensive products with Japan and the USA, CO2 emissions are estimated for ten East Asian countries between 1988 and 2000. Our results show that increasin...

Overall Significance/Background The central dogma of DNA enzymology has long held that for two pieces of DNA to be ligated, the respective DNA pieces must bear a hydroxyl on the 3′-end and a phosphate on the 5′-end. All of the other types of DNA ends are considered incorrect or “dirty,” as they cannot be joined by classic DNA ligases. However, intrinsic and extrinsic DNA damage often results in...

Distributional dominance criteria are commonly applied to draw welfare inferences about comparisons, but conclusions drawn from empirical implementations of dominance criteria may be inßuenced by data contamination. We examine a non-parametric approach to reÞning Lorenz-type comparisons and apply the technique to two important examples from the LIS data-base. ¤
