Forecasting Field Defect Rates Using a Combined Time-based and Metrics-based Approach: a Case Study of OpenBSD
Luo Li, Paul; Herbsleb, James; Shaw, Mary - 2005
Open source software systems are critical infrastructure for many applications; however, little has been precisely measured about their quality. Forecasting the field defect-occurrence rate over the entire lifespan of a release before deployment for open source software systems may enable...

Examining the Cross-National Applicability of Multi-Item, Multidimensional Measures using Generalizability Theory
Durvasula, Srinivas; Netemeyer, Richard G.; Andrews, J. … - 2006
cross-nationally. Typically, researchers have relied upon the tenets of classical measurement theory (CT) using confirmatory …-national applicability? Our research seeks to address these issues and the cross-national measurement applicability of multi …-dimensional scales via generalizability theory (GT). In this paper, we use a cross-national data set and simulated data sets to …

Measuring Unemployment Insurance Generosity
Pallage, Stephane; Scruggs, Lyle; Zimmermann, Christian - 2008
In this paper, we develop a methodology to summarize the various policy parameters of an unemployment insurance scheme into a single generosity parameter. Unemployment insurance policies are multdimensional objects. They are typically defined by waiting periods, eligibility duration, benefit...

Reliability generalization: lapsus linguae
Smith, Julie Marilyn - 2011
This study examines the proposed Reliability Generalization (RG) method for studying reliability. RG employs the application of meta-analytic techniques similar to those used in validity generalization studies to examine reliability coefficients. This study explains why RG does not provide a...

Effect of NAFTA on Mexico's Income Distribution in the Presence of Migration
Garduno-Rivera, Rafael - 2010
This paper asks how NAFTA affected income distribution within Mexico considering changes in internalmigration. Trade liberalization should theoretically increase the income of low-skilled workers in low-skilled labor-abundantdeveloping countries. Thus, by increasing the wages of poorer workers,...

Farm level effects of EU policy liberalization: Simulations based on an EU-wide agricultural sector model and a supply model of the German agricultural sector
Deppermann, Andre; Grethe, Harald; Offermann, Frank - 2010
The impact of sectoral or economy wide policy scenarios is often of strong political and public interest, yet it is a scientific challenge. When analyzing different levels of aggregation, the use ofsingle models may not be sufficient. In this paper we establish an interface between the European...
