- Background: The availability of International Standards for thromboplastin is essential for the calibration of routine reagents and hence the calculation of the International Normalized Ratio (INR). Stocks of the current Fourth International Standards are running low. Candidate replacement materials have been prepared. This article describes the calibration of the proposed Fifth International Standards for thromboplastin, rabbit, plain (coded RBT/16) and for thromboplastin, recombinant, human, plain (coded rTF/16). Methods: An international collaborative study was carried out for the assignment of International Sensitivity Indexes (ISIs) to the candidate materials, according to the World Health Organization (WHO) guidelines for thromboplastins and plasma used to control oral anticoagulant therapy with vitamin K antagonists. Results: Results were obtained from 20 laboratories. In several cases, deviations from the ISI calibration model were observed, but the average INR deviation attributabled to the model was not greater than 10%. Only valid ISI assessments were used to calculate the mean ISI for each candidate. The mean ISI for RBT/16 was 1.21 (between-laboratory coefficient of variation [CV]: 4.6%), and the mean ISI for rTF/16 was 1.11 (between-laboratory CV: 5.7%). Conclusions: The between-laboratory variation of the ISI for candidate material RBT/16 was similar to that of the Fourth International Standard (RBT/05), and the between-laboratory variation of the ISI for candidate material rTF/16 was slightly higher than that of the Fourth International Standard (rTF/09). The candidate materials have been accepted by WHO as the Fifth International Standards for thromboplastin, rabbit plain, and thromboplastin, recombinant, human, plain.

- Evaluation of research uses peer review and bibliometrics, and the debate about their balance in research evaluation continues. Both approaches have supporters, and both approaches are criticized. In this paper, we describe an interesting case in which the use of bibliometrics in a panel-based evaluation of a mid-sized university was systematically tried out. The case suggests a useful way in which bibliometric indicators can be used to inform and improve peer review and panel-based evaluation. We call this ‘disciplined peer review’, and disciplined is used here in a constructive way: Bibliometrically disciplined peer review is more likely to avoid the subjectivity that often influences the outcomes of the peer and panel review-based evaluation.

- The main rationale behind career grants is helping top talent to develop into the next generation leading scientists. Does career grant competition result in the selection of the best young talents? In this paper we investigate whether the selected applicants are indeed performing at the expected excellent level-something that is hardly investigated in the research literature.We investigate the predictive validity of grant decision-making, using a sample of 260 early career grant applications in three social science fields. We measure output and impact of the applicants about ten years after the application to find out whether the selected researchers perform ex post better than the non-successful ones. Overall, we find that predictive validity is low to moderate when comparing grantees with all non-successful applicants. Comparing grantees with the best performing non-successful applicants, predictive validity is absent. This implies that the common belief that peers in selection panels are good in recognizing outstanding talents is incorrect. We also investigate the effects of the grants on careers and show that recipients of the grants do have a better career than the non-granted applicants. This makes the observed lack of predictive validity even more problematic.

- Do funding modes have an effect on the quality of knowledge production? In this paper we develop an approach to investigate this, using the new WoS field on funder data, using climate change research in Sweden and the Netherlands in 2009-2010 as a case. We firstly developed an operational definition of climate change research, and retrieved all WoS records for the countries and years mentioned. We developed a classification scheme for the funding organizations of 13 categories, using dimensions as top-down/bottom-up, large/small research, national/international, and public/private. Then all funding institutions were manually classified in the 13 categories. We then calculated the average impact of the papers for each of the funding categories. The results clearly show differences between the funder types, and also between the countries. The latter indicates that a funding mode may be organized in different ways affecting the effectiveness. Finally, we discuss further research.
