•Interpreting renewable procurement prices at their face value can be misleading.•New method shows how compared like-for-like.•The level and composition of offshore wind revenue varies globally.•Support regimes remain essential even when direct subsidy payments decline. Procurement are increasingly used to gauge the financial performance costs energy projects. Comparing from auctions or contrac...

This paper investigates fairness in writing test scores terms of candidates who completed a either by hand or typed, on computer. The data for this large-scale comparability study comprise taking English language tests at four CEFR levels – B1 to C2 the period 2019–2022. were analysed via effect size differences and equivalence tests. Measured size, small amount difference was apparent obtained...

A k-subcoloring of a graph is a partition of the vertex set into at most k cluster graphs, that is, graphs with no induced P3. 2-subcoloring is known to be NP-complete for comparability graphs and three subclasses of planar graphs, namely triangle-free planar graphs with maximum degree 4, planar perfect graphs with maximum degree 4, and planar graphs with girth 5. We show that 2-subcoloring is ...

In this paper, we present a linear-time algorithm for substitution decomposition on chordal graphs. Based on this result, we develop a linear-time algorithm for transitive orientation on chordal comparability graphs, which reduces the complexity of chordal comparability recognition from O(n) to O(n+m). We also devise a simple linear-time algorithm for interval graph recognition where no complic...

This paper will address some of the conceptual issues that arise when interpreting the results of the multilevel modelling of comparability between examinations. Some of the comparability studies carried out by the Research and Evaluation Division of the University of Cambridge Local Examinations Syndicate will be used to illuminate the conceptual issues involved. The differences in interpretat...

The objective of this paper is to evaluate the semantic building block-based approach as a means for improving comparability in business process modelling. It is described whether and why the semantic building block-based approach reduces the variations in comparison to traditional modelling approaches. Our argumentation is grounded on the assumption that business process modelling projects in ...

2. The usefulness of a multi-country database depends on the extent of cross-country comparability of its stored data. Thus, to assure sound use of their cross-country statistical data, international data sources are responsible for providing users with, in addition to general information for the overall database, relevant and detailed qualitative information that indicates the applicability an...

Assessing the comparability of different groups is an issue facing many researchers and evaluators in a variety of settings. Commonly, null hypothesis significance testing (NHST) is incorrectly used to demonstrate comparability when a non-significant result is found. This is problematic because a failure to find a difference between groups is not equivalent to showing that the groups are compar...
