ReproZip: The Reproducibility Packer

ReproZip: Using Provenance to Support Computational Reproducibility

We describe ReproZip, a tool that makes it easier for authors to publish reproducible results and for reviewers to validate these results. By tracking operating system calls, ReproZip systematically captures detailed provenance of existing experiments, including data dependencies, libraries used, and configuration parameters. This information is combined into a package that can be installed and...

An analytical model is developed to explain the increasing tendency of pork packers to produce their own hogs, based on Grossman and Hart’s property rights theory of the firm. Packer upstream integration is linked to the need to align packer-producer investment incentives in an environment marked by increasing hog buyer consolidation, changing consumer demands, moves toward traceability in the ...

PACKER: An Exemplar Model of Category Generation

Generating new concepts is an intriguing yet understudied topic in cognitive science. In this paper, we present a novel exemplar model of category generation: PACKER (Producing Alike and Contrasting Knowledge using Exemplar Representations). PACKER’s core design assumptions are (1) categories are represented as exemplars in a multidimensional psychological space, (2) generated items should be s...
