Reproducibility and repeatability dramatically increase the value of scientific experiments, but remain two challenging goals for the experimenters. Similar to the LAMP stack that considerably eased the web developers life, in this paper, we advocate the need of an analogous software stack to help the experimenters making reproducible research. We propose the EnosStack, an open source software stack especially designed for reproducible scientific experiments. EnosStack enables to easily describe experimental workflows meant to be re-used, while abstracting the underlying infrastructure running them. Being able to switch experiments from a local to a real testbed deployment greatly lower code development and validation time. We describe the abstractions that have driven its design, before presenting a real experiment we deployed on Grid'5000 to illustrate its usefulness. We also provide all the experiment code, data and results to the community.
In this case study, the authors present one library’s work to help increase awareness of reproducibility and to build capacity for our institution to improve reproducibility of ongoing and future research.
In recent years, evidence has emerged from disciplines ranging from biology to economics that many scientific studies are not reproducible. This evidence has led to declarations in both the scientific and lay press that science is experiencing a “reproducibility crisis” and that this crisis has significant impacts on both science and society, including misdirected effort, funding, and policy implemented on the basis of irreproducible research. In many cases, academic libraries are the natural organizations to lead efforts to implement recommendations from journals, funders, and societies to improve research reproducibility. In this editorial, we introduce the reproducibility crisis, define reproducibility and replicability, and then discusses how academic libraries can lead institutional support for reproducible research.
This chapter is written to help undergraduate students better understand the role of replication in psychology and how it applies to the study of social behavior. We briefly review various replication initiatives in psychology and the events that preceded our renewed focus on replication. We then discuss challenges in interpreting the low rate of replication in psychology, especially social psychology. Finally, we stress the need for better methods and theories to learn the right lessons when replications fail.
Reproducibility in experiments is necessary to verify claims and to reuse prior work in experiments that advance research. However, the traditional model of publication validates research claims through peer-review without taking reproducibility into account. Workflows encapsulate experiment descriptions and components and are suitable for representing reproducibility. Additionally, they can be published alongside traditional patterns as a form of documentation for the experiment which can be combined with linked open data. For reproducibility utilising published datasets, it is necessary to declare the conditions or restrictions for permissible reuse. In this paper, we take a look at the state of workflow reproducibility through a browser based tool and a corresponding study to identify how workflows might be combined with traditional forms of documentation and publication. We also discuss the licensing aspects for data in workflows and how it can be annotated using linked open data ontologies.
This document reviews the stability of the main LHC operational parameters, namely orbit, tune, coupling and chromaticity. The analysis will be based on the LSA settings, measured parameters and real-time trims. The focus will be set on ramp and high energy reproducibility as they are more diflicult to assess and correct on a daily basis for certain parameters like chromaticity and coupling. The reproducibility of the machine in collision will be analysed in detail, in particular the beam offsets at the IPS since the ever decreasing beam sizes at the IPs make beam steering at the IP more and mode delicate.
