This paper argues that research performance is essentially a multidimensional concept which cannot be encapsulated into a single universal criterion. Various indicators used in quantitative studies on research performance at micro or meso-levels can be classified into two broad categories: (i) objective or quantitative indicators (e.g. counts of publications, patents, algorithms or other artifacts of research output) and (ii) subjective or qualitative indicators which represent evaluative judgement of peers, usually measured on Likert or semantic differential scales. Because of their weak measurement properties, subjective indicators can also be designated as quasi-quantitative measures. This paper is concerned with the factorial structure and construct validity of quasi-quantitative measures of research performance used in a large-scale empirical study carried out in India. In this study, a reflective measurement model incorporating four latent variables (R & D effectiveness, Recognition, User-oriented effectiveness and Administrative effectiveness) is assumed. The latent variables are operationalized through thirteen indicators measured on 5-point semantic differential scales. Convergent validity, discriminant validity and reliability of the measurement model are tested through LISREL procedure.

In this work, the author offers a valid description of the basalt scree slope stones-grassland (Geranio rotundifolio-Sedetum albi Jakucs ex Soó 1973), whose depiction used to be incomplete. The author publishes 15 relevés of the association concerning the basalt volcanic hills of the northern Transdanubian (Hungary) region - characterised by distinctive flora and vegetation -, determines the characteristic features, habitat conditions as well as geographical distribution of the association. Column 2 of Table 2 has been selected as the neotype relevé of the association.
The authors continue their considerations concerning the validity of the steady-state approximation in non-isothermal kinetics.
A sequence of two first-order consecutive reactions with an active intermediate was subjected to kinetic analysis by numerical
solution of the corresponding differential kinetic equations for a number of particular cases. The results demonstrated that
the rate of change of concentration of the active intermediate is negligibly small if the assumption made in the isothermal
case is also accepted for the non-isothermal case, i.e. k2(T(t))>>
This paper examines the peer review procedure of a national science funding organization (Swiss National Science Foundation)
by means of the three most frequently studied criteria reliability, fairness, and validity. The analyzed data consists of
496 applications for project-based funding from biology and medicine from the year 1998. Overall reliability is found to be
fair with an intraclass correlation coefficient of 0.41 with sizeable differences between biology (0.45) and medicine (0.20).
Multiple logistic regression models reveal only scientific performance indicators as significant predictors of the funding
decision while all potential sources of bias (gender, age, nationality, and academic status of the applicant, requested amount
of funding, and institutional surrounding) are non-significant predictors. Bibliometric analysis provides evidence that the
decisions of a public funding organization for basic project-based research are in line with the future publication success
of applicants. The paper also argues for an expansion of approaches and methodologies in peer review research by increasingly
focusing on process rather than outcome and by including a more diverse set of methods e.g. content analysis. Such an expansion
will be necessary to advance peer review research beyond the abundantly treated questions of reliability, fairness, and validity.
