Measuring Organizational Performance: A Case for Subjective Measures

Abstract: We review the organisational performance (OP) measurement literature highlighting the limitations of both objective and subjective measures of performance. We argue that, with careful planning, subjective measures can be successfully employed to assess OP. This is because often consistent, reliable and comparable compatible objective data on OP measures—particularly across countries and sectors—is difficult to come by. Considering that an inflated OP measure can be cross-checked with the use of secondary data, managers have little incentive to report such figures. As a result, when quizzed over the stand-alone performance measures of their organisations or vis-a-vis their rivals, managers accurately assess and respond to questions on the performance of their organisations. An in-depth statistical exercise conducted on the subjective measures of OP as reported by managers of four sets of companies in four separate countries, show consistent results, thus lending support to this premise.

Development and initial validation of an instrument to assess the motivational qualities of music in exercise and sport: The Brunel Music Rating Inventory

Abstract: Equivocal results of the psychophysical effects of music have been explained in part by the insensitivity of researchers to important personal and situational variables when selecting music. The aim of the present study was to operationalize a conceptual framework for the prediction of psychophysical responses to music into a music rating inventory to assess the motivational qualities of music in exercise and sport environments. An initial item pool was developed and administered to 334 aerobics instructors. Exploratory factor analysis produced a 13-item, four-factor structure (association, musicality, cultural impact and rhythm response), which accounted for 59.2% of the variance. This model demonstrated acceptable fit indices when tested using confirmatory factor analysis on 314 exercise-to-music participants, and was better than an alternative two-factor model. When cross-validated using multisample confirmatory factor analysis, the model also showed an acceptable fit overall, although some invariance in the rhythm response factor was evident that can be attributed to the exclusive use of synchronous music by aerobics instructors. The Brunel Music Rating Inventory appears to be a valid and reliable tool for both researchers and practitioners to assess the motivational qualities of music in exercise and sport environments.

Structure-activity relationships in the development of hypoxic cell radiosensitizers. I. Sensitization efficiency

Abstract: SummaryThe efficiency of 35 nitroaromatic and nitroheterocyclic compounds in radiosensitizing hypoxic Chinese Hamster cells in vitro was determined. The concentration C of the compound required to achieve an enhancement ratio of 1·6 was measured, and the redox and partition properties were quantified as the one-electron reduction potential at pH 7, E, and the octanol: water partition coefficient, P, respectively. Most of the compounds studied were 2-nitroimidazoles, but some 4- and 5-nitroimidazoles, 5-nitrofurans and nitrobenzenes were investigated for comparison. Together with data for nine nitroimidazoles previously reported, the results were fitted to a structure-activity relationship of the form using multiple linear regression analysis. Statistical tests showed that the coefficients b2 and b3 were not significantly different from zero and the simpler equation, obtained by omitting the terms in log P, explained 85 per cent of the variance in log C. Earlier reports that the radiosensitization efficien...
