A Measure of Staff Perceptions of Quality-Oriented Organizational Performance: Initial Development and Internal Consistency

The present study originated from a university's effort to develop a Total Quality Management (TQM) system for improving the quality of staff services. This extends TQM into a major service sector, higher education, which has only recently begun to explore TQM applications. Integral to this effort was the development of an instrument for assessing service quality based on staff perceptions. The instrument was based on a core set of dimensions identified as common to the Malcolm Baldridge National Quality Award, and the psychology and management literatures. Initial support for this instrument came from high reliability coefficients for each of the component scales. Recommendations for further validation efforts and potential practical applications are also discussed.

Measuring the quality of managerial learning on the job

This article describes the development of an instrument to measure the quality of managerial learning on the job. The instrument can be used to analyse the quality of the individual learning process on the job. The literature shows that two factors determine the quality of the learning process: the learning potential of the job context and the way in which the manager approaches their work. So the instrument has two components. The first component measures the four types of work experience that offer potential opportunities for individual learning. These are transitions, task-related characteristics, obstacles and support. The second component, the so-called learning behaviour, analyses the way the individual approaches the potential learning opportunities present in the job. This can also be divided into four categories: emergent learning, planned learning, instruction-oriented learning and meaning-oriented learning. Based on these two components, an instrument has been developed to measure the quality of learning on the job. This has been shown to be valid and reliable in a sample of European managers.     

Issues in the Design and Analysis of Panel Studies: A Cursory Review

This paper offers a broad review of some aspects in the design and analysis of panel studies, chiefly of household panel surveys. Both the analytic benefits and the potential problems of panel surveys are briefly outlined, and selected methodological and operational issues, which crucially affect data quality are highlighted. These questions are then considered under four headings: (i) dynamic population and its implications for initial sampling and following rules; (ii) panel length and number of waves; (iii) tracking and tracing techniques, and other strategies for maintaining high participation rates; (iv) questionnaire design and strategies for collecting retrospective information. While no technical details are offered, there is some discussion of the possible drawbacks and advantages of the different approaches described.     

Institutional perspective of financial sector development: A multidimensional assessment

Financial sector development is a multidimensional process that plays a vital role in the economic growth and development of a country. This study investigates the effect of institutional quality on multidimensional financial sector development, and its dimensions, such as, depth, access, and efficiency. We used a panel dataset of 85 emerging and developing economies from 1996 to 2018 for analysis. Our findings based on 2SLS estimation demonstrate that institutional quality has a significant positive effect on the progress of the financial sector, especially its depth, access, and efficiency. The breakdown analysis shows that most of the key components (control of corruption, government effectiveness, regulatory quality, rule of law, and voice and accountability) of institutional quality enhance the financial sector development. Our empirical results are robust across alternative measures of institutional quality, split-sample analysis, alternative instrument, and estimator. This paper also offers useful policy implications to the stakeholders in emerging and developing economies.
