Do altmetrics correlate with the quality of papers? A large-scale empirical study based on F1000Prime data
In this study, we address the question whether (and to what extent,
respectively) altmetrics are related to the scientific quality of papers (as
measured by peer assessments). Only a few studies have previously investigated
the relationship between altmetrics and assessments by peers. In the first
step, we analyse the underlying dimensions of measurement for traditional
metrics (citation counts) and altmetrics - by using principal component
analysis (PCA) and factor analysis (FA). In the second step, we test the
relationship between the dimensions and quality of papers (as measured by the
post-publication peer-review system of F1000Prime assessments) - using
regression analysis. The results of the PCA and FA show that altmetrics operate
along different dimensions, whereas Mendeley counts are related to citation
counts, and tweets form a separate dimension. The results of the regression
analysis indicate that citation-based metrics and readership counts are
significantly more related to quality, than tweets. This result on the one hand
questions the use of Twitter counts for research evaluation purposes and on the
other hand indicates potential use of Mendeley reader counts
Applied Evaluative Informetrics: Part 1
This manuscript is a preprint version of Part 1 (General Introduction and
Synopsis) of the book Applied Evaluative Informetrics, to be published by
Springer in the summer of 2017. This book presents an introduction to the field
of applied evaluative informetrics, and is written for interested scholars and
students from all domains of science and scholarship. It sketches the field's
history, recent achievements, and its potential and limits. It explains the
notion of multi-dimensional research performance, and discusses the pros and
cons of 28 citation-, patent-, reputation- and altmetrics-based indicators. In
addition, it presents quantitative research assessment as an evaluation
science, and focuses on the role of extra-informetric factors in the
development of indicators, and on the policy context of their application. It
also discusses the way forward, both for users and for developers of
informetric tools.Comment: The posted version is a preprint (author copy) of Part 1 (General
Introduction and Synopsis) of a book entitled Applied Evaluative
Bibliometrics, to be published by Springer in the summer of 201
Enhancing the Impact of Cross-Sector Partnerships. Four Impact Loops for Channeling Partnership Studies
This paper addresses the topic of this special symposium issue: how to enhance the impact of cross-sector partnerships. The paper takes stock of two related discussions: the discourse in cross-sector partnership research on how to assess impact and the discourse in impact assessment research on how to deal with more complex organizations and projects. We argue that there is growing need and recognition for cross-fertilization between the two areas. Cross-sector partnerships are reaching a paradigmatic status in society, but both research and practice need more thorough evidence of their impacts and of the conditions under which these impacts can be enhanced. This paper develops a framework that should enable a constructive interchange between the two research areas, while also framing existing research into more precise categories that can lead to knowledge accumulation. We address the preconditions for such a framework and discuss how the constituent parts of this framework interact. We distinguish four different pathways or impact loops that refer to four distinct orders of impact. The paper concludes by applying these insights to the four papers included in this special issue

Lessons Learned and Next Steps in Energy Efficiency Measurement and Attribution: Energy Savings, Net to Gross, Non-Energy Benefits, and Persistence of Energy Efficiency Behavior
This white paper examines four topics addressing evaluation, measurement, and attribution of direct and indirect effects to energy efficiency and behavioral programs: Estimates of program savings (gross); Net savings derivation through free ridership / net to gross analyses; Indirect non-energy benefits / impacts (e.g., comfort, convenience, emissions, jobs); and, Persistence of savings

Nanotechnology: A Policy Primer
[Excerpt] Nanoscale science, engineering, and technology—commonly referred to collectively as nanotechnology—is believed by many to offer extraordinary economic and societal benefits. Congress has demonstrated continuing support for nanotechnology and has directed its attention primarily to three topics that may affect the realization of this hoped for potential: federal research and development (R&D) in nanotechnology; U.S. competitiveness; and environmental, health, and safety (EHS) concerns. This report provides an overview of these topics—which are discussed in more detail in other CRS reports—and two others: nanomanufacturing and public understanding of and attitudes toward nanotechnology
