This empirical study introduces population targeting and cut-off point targeting as a systematic approach to evaluating the performance of items in the English section of university entrance examinations. Using Rasch measurement theory, we found that the item difficulty and the types of items in a series of national university entrance examinations varied considerably over a 4-year period. However, there was progress towards improved test performance in terms of an increased number of items assessing different language skills and content areas as well as an increased number targeting test takers’ knowledge of English. This study also found that productive items rather than receptive items better targeted test takers’ overall knowledge of English. Moreover, productive items were more consistently located around the probable cut point for university admissions. The paper concludes with a detailed account of a number of probable factors that could influence item performance, such as the use of rating scales. 本論文では、ある国立大学における大学入試の英語の問題の変化を実証的に検証したものである。テスト項目の結果を検証するための体系的なアプローチとして、「母集団を対象としたアプローチ」および「足きり点を対象としたアプローチ」という方法を導入した。ラッシュ・モデリングを用いて分析した結果、過去４年間の間に、項目の困難度および項目の型について、様々な技能を測定していること、内容も多様であること、英語の知識を検証している項目が増えたこと、などの点で大きく変化していることがわかった。さらに、産出能力の方が受容能力を測定する項目よりも入学者決定の際の足きり点の周辺に収束する傾向が見られた。項目ごとの成績に影響を及ぼす可能性のある多様な要因について詳細な検討を行った。

AbstractThis paper examines the impact of an educational programme developed in Senegal with university students and designed to encourage entrepreneurship by influencing personal attitudes toward enterprise. The instrument to measure the entrepreneurial potential of young people has been applied in different socio-demographic contexts in some previous empirical research. Improvements in students’ perception of attitudinal factors associated with leadership, creativity, achievement and intuition can be inferred from the results of the longitudinal analysis conducted. Moreover, a positive and significant relationship between students’ perceived behavioural control and their attitudes toward starting a business at the end of the entrepreneurial programme is confirmed. Rasch Measurement Theory is applied to analyse the validity of the measurements and findings suggest that the scale used seems to be a reliable and valid tool for measuring entrepreneurial attitude in a university setting. Results confirm that entrepreneurship programmes have the potential to improve the entrepreneurial attitudes of students in a developing country.

Conceptual Problems

Decoherence is widely felt to have something to do with the quantum measurement problem, but getting clear on just what is made difficult by the fact that the ‘measurement problem’, as traditionally presented in foundational and philosophical discussions, has become somewhat disconnected from the conceptual problems posed by real physics. This, in turn, is because quantum mechanics as discussed in textbooks and in foundational discussions has become somewhat removed from scientific practice, especially where the analysis of measurement is concerned. This paper has two goals: firstly (§§1–2), to present an account of how quantum measurements are actually dealt with in modern physics (hint: it does not involve a collapse of the wave function) and to state the measurement problem from the perspective of that account; and secondly (§§3–4), to clarify what role decoherence plays in modern measurement theory and what effect it has on the various strategies that have been proposed to solve the measurement problem.

New Perspective

Purpose The purpose of this paper is to define a general and common construct in order to measure the level of difficulty companies experience when they implement continuous improvement (CI). Additionally, a rank of barriers is obtained together with a rank of companies. Design/methodology/approach In order to achieve the objective, first, a literature review is carried out to specify the domain of the construct; second, a sample of items is selected; third a survey is carried out in companies that have already implemented CI initiatives, the results being thus limited to this population; fourth, measures are purified by analysing the reliability and validity of the measurements, and finally results are obtained. The Rasch measurement theory will be used to provide a new perspective on a mature research topic. Findings It can be concluded that a new valid construct has been defined together with a rank of CI barriers, being lack of time the main barrier. A rank of companies is also obtained which is a first step in the development of future research studies. Practical implications Managers are provided with a better understanding of the barriers that can obstruct CI implementation. Thus, the rank of CI barriers guides managers through the most common and important obstacles so that they will be able to plan better CI strategies. In addition, the rank of companies allows each company to undertake a benchmarking exercise. Originality/value This work proposes a new way of analysing the difficulty in implementing CI as a continuum, rather than as independent barriers. From a theoretical point of view, it defines a new construct and offers a rank of CI barriers together with a rank of companies based on their level of difficulty when implementing CI initiatives. This is something new, as previous studies were mainly focussed on the items side. From a practical point of view, this study offers the surveyed companies the opportunity to see how they are positioned with respect to the other companies. Moreover, this rank of companies is the foundation on which to develop further studies with a practical orientation in the future.
