Understanding change in the public sector:a local authority case study

Increasingly managers in the public sector are being required to manage change, but many of the models of change which are available to them have been developed from private sector experience. There is a need to understand more about how the change process unfolds in the public sector. A case study of change in one local authority over the period 1974-87 is provided. The events surrounding housing decentralisation and the introduction of community development are considered in detail. To understand these events a twofold model of change is proposed: a short wave model which explains a change project or event; and a long wave model which considers how these projects or events might be linked together to provide a picture of an organisation over a longer period. The short wave model identifies multiple triggers of change and signals the importance of mediators in recognising these triggers. The extent to which new ideas are implemented and the pace of their adoption is influenced by the balance of power within the organisation and the political tactics which are used. Broad phases in the change process can be identified, but there is not a simple linear passage through these. The long wave model considers the way in which continuity and change feed off one another. It suggests that periods of relative stability may be interspersed with more radical transformations as the dominant paradigm guiding the organisation shifts. However, such paradigmatic shifts in local government may be less obvious than in the private sector due to the diverse nature of the former.

Receiver sensitivity in optical and microwave, heterodyne and homodyne systems

In this paper, we analyze the sensitivities of coherent optical receivers and microwave receivers. We derive theoretical limits of signal-to-noise ratio and bit error rate. By applying a generic approach to a broad range of receivers, we can compare their performance directly. Other publications have considered some of these receivers. However, their diverse nature obscures the big picture. Using our results as a unifying platform, previous publications can be compared and discrepancies between them identified.

Transplanting Anglo-American accounting oversight boards to a diverse institutional context

The introduction of accounting and auditing oversight boards (OBs) has been promoted on a global scale as a key component of the international financial architecture that has emerged over the past two decades. Such institutions, modeled on the Anglo-American tradition, are domestically organized and embedded within distinctively diverse institutional contexts. Their role is to ease agency problems, improve the quality of financial reporting, and help provide stability in the global financial system. We employ an institutional approach, located within the broader political economy framework of global capitalism, to examine the establishment and operation of the new regulatory regime in Greece. Greece, a member of the European Union, exhibits characteristics of a "delegative" democracy, i.e. a traditionally weak institutionalization, reform (in)capacity problems and a clientelistic political system. Our case study shows that the formation and operation of the newly-established system of oversight is conditioned by local political and economic constraints and, thus, does not automatically translate into concrete benefits for the quality of financial reporting. We also draw attention to the structural mismatch between a progressing globalized financial integration and the fragmented nature of the system of oversight, and illustrate that OBs' independence from local governments is an important but neglected issue.
