Do Consumers Really Follow a Rule of Thumb? Three Thousand Estimates from 130 Studies Say “Probably Not”
Havránek, Tomáš ; Sokolova, Anna
We show that three factors combine to explain the mean excess sensitivity reported in studies estimating consumption Euler equations: the use of macro data, publication bias, and liquidity constraints. When micro data are used, publication bias is corrected for, and the households under examination do not face liquidity constraints, the literature implies no evidence for the excess sensitivity of consumption to income. Hence little remains for pure rule-of-thumb behavior. The results hold when we control for 45 additional variables reflecting the methods employed by researchers and use Bayesian model averaging to account for model uncertainty. The estimates of excess sensitivity are also systematically affected by the order of approximation of the Euler equation, the treatment of non-separability between consumption and leisure, and the choice of proxy for consumption.

TIB AV-Portal: A Reliable Infrastructure for Scientific Videos
Plank, Margret
The German National Library of Science and Technology provides a web-based platform for quality-tested scientific videos including computer visualizations, experiments, interviews as well as recordings of lectures and conferences. Key feature of the portal is the use of automated video and semantic analyses, which enables pinpoint and cross lingual search on a segment level. All videos are assigned by Digital Object Identifi ers (DOI). As a result videos can be published in a scientifically sound way and be linked via DOIs to other research work like the corresponding article.

National grey literature cooperation model
Pejšová, Petra ; Vyčítalová, Hana
The National Library of Technology (NTK) has a long tradition of collecting grey literature on the national level. NTK became SIGLE system partner in the 1980s and from 2008 it has been the coordinator of the National Repository of Grey Literature (NRGL). NTK has created a grey literature partnership network in the Czech Republic. Over 130 institutions dedicated to research, science, education, culture etc. participate in this network and provide grey literature to the NRGL. NTK manages cooperation among these institutions and NRGL, provides methodology and standards, and deals with the legal aspects of repository management and collecting grey literature. We have created a model of the main parties involved in collecting and publishing grey literature in order to gain a better insight in the structure, and to enhance further cooperation. We defined the role of partners, type of participants, services, and tools used for grey literature publishing. In our poster, we would like to present the Czech national model as an inspiration for institutions in other countries.

Challenges in Providing Unpublished Research Data in Biomedical Engineering to Grey Literature Repositories
Francová, Pavla ; Krueger, Stephanie
Regardless of the scientific field or focus, every researcher produces during his or her career a multitude of unpublished research data such as laboratory diaries, grant proposals, images etc. Although making such data more accessible undoubtedly has value for researchers, they are currently not shared in open repositories. Why are researchers still reluctant to actively use grey literature repositories for unpublished contextual materials and data? Authors will discuss how scientists might be encouraged to add such material to grey literature repositories and specific examples of unpublished research data will be shown in connection to model scientifi c project.
