The Distributional Characteristics of a Selection of Contracts Traded on the London International Financial Futures Exchange

This study examines the distributional properties of futures prices for contracts traded on LIFFE. A filtering process is employed to remove day of the week and holiday effects, a maturity effect, moving average effects and the influence of an asset's conditional variance from the raw returns series. Alternative distributional models from the stable paretian and ARCH families are examined for their applicability to futures data using a stability under additions. The results conclusively reject the hypothesis that futures returns are normally distributed with findings in favour of two related hypotheses – the mixtures of stable distribution and the ordinary stable distribution.     

Investigating productivity change and hospital size: a nonparametric frontier approach

The study obtains measures of the productive efficiency of ‘larger’ and ‘smaller’ Northern Ireland hospitals during the 1986–92 pre-Trust period. The measures provide insights into how these hospitals were responding to the pressures for increased efficiency prior to Trust status. They also constitute a useful benchmark for evaluating productivity change under the post-1992 Trust status environment. A nonparametric frontier approach is used to measure productivity change and to decompose this into technical change (or shifts in the best practice frontier) and efficiency change (or change in how far a hospital is from the frontier). The latter change in efficiency is also decomposed into changes in scale efficiency, pure technical efficiency and input congestion. The findings indicate that smaller hospitals, starting from a less efficient base, achieved greater productivity gains than larger hospitals over 1986–92. For smaller hospitals, this was due to progressive shifts in the best practice frontier outweighing a substantial decline in efficiency. This decline was found to be due to a deterioration in scale efficiency over the period. The results overall support the current policy view that larger hospitals are more efficient than smaller hospitals in providing health care services.     

A more ideal system?

“Although American higher education can justifiably take pride in its capacity to develop the student's ability to manipulate the material world through its programs in science, medicine, technology, and commerce, it has paid relatively little attention to the student's “inner” development—the sphere of values and beliefs, emotional maturity, moral development, spirituality, and self‐understanding.” —from the Foreword to Encouraging Authenticity and Spirituality in Higher Education by Alexander W. Astin and Helen S. Astin     

Framing the constructive alignment of design within technology subjects in general education

Design is core element of general technology education internationally. While there is a degree of contention with regards to its treatment, there is general consensus that the inclusion of design in some form is important, if not characteristic, of the subject area. Acknowledging that design is important, there are many questions which need to be considered in order to guide policy and practice, such as whether a singular general design ability can be explicitly defined empirically beyond an implicit verbal definition, and whether it can be taught and assessed. In order to address these questions in a systematic fashion, a framework is needed in order to guide relevant investigations. Having such a framework would allow for theory to be generated, hypotheses to be tested, and assumptions to be challenged. In response to this apparent need, this article presents a theoretical discussion pertaining to the constructive alignment of learning to design, wherein theories of knowledge, variation theory, knowledge transfer, and assessment validity and reliability are reflected upon.

     

The diversification and financial performance of US credit unions

For US credit unions, revenue from non-interest sources has increased significantly in recent years. We investigate the impact of revenue diversification on financial performance for the period 1993–2004. The impact of a change in strategy that alters the share of non-interest income is decomposed into a direct exposure effect, reflecting the difference between interest and non-interest bearing activities, and an indirect exposure effect which reflects the effect of the institution’s own degree of diversification. On both risk-adjusted and unadjusted returns measures, a positive direct exposure effect is outweighed by a negative indirect exposure effect for all but the largest credit unions. This may imply that similar diversification strategies are not appropriate for large and small credit unions. Small credit unions should eschew diversification and continue to operate as simple savings and loan institutions, while large credit unions should be encouraged to exploit new product opportunities around their core expertise.     

An Examination of Key Factors of Influence in the Development Process of Credit Union Industries

The aim of this paper is to analyse credit union industries within a development framework. Explicit consideration is given to credit union industries in four countries – Great Britain, Ireland, New Zealand and the United States. It is argued that in terms of a developmental typology the credit union industry in Great Britain is at a nascent stage of development, the industries in Ireland and New Zealand are at a transition stage while the US credit union industry is mature in nature. In progression between stages the analysis considers the influence of factors such as situational leadership, the complexion of trade associations, professionalisation, regulatory and legislative initiatives and technology. The analysis concluded that while there was a substantial commonality of experience, there were also significant differences in the impact of these factors. This consequently encouraged the recognition of the existence of 'a variety of the species' in respect of credit union development.
