Institutions, Ideology, and the Tragedy of the Commons: West Texas Groundwater Policy

West Texas is the setting for an unintended experiment in commonsresource management. Dispersed, autonomous, local groundwaterdistricts use nonregulatory strategies to promote conservationand groundwater quality. The central force driving this organizationalform appears to be ideological. West Texans seek alternativesto state management of groundwater pumping. This study useskey-informant interviews to evaluate the strength of ideologyin explaining West Texas groundwater policy and to provide atheoretical framework for discussing the importance of the "localsolution.’ Time-series data substantiate the claim thatlocal groundwater districts succeed in slowing depletion rates.     

Evaluating a new computer-based system for face recall

The Computer-Aided Design Centre has developed a new face recall system which enables a witness to construct the image of a suspect on a television screen. The system currently uses the Photofit library and method of construction. Likenesses of target faces produced by subjects (n=36) using the new system were compared to conventional Photofits produced by a second group of subjects (n=36) of the same targets. There was no difference on any of the three measures employed in the assessed quality of the likenesses produced by Photofit and the CADC System. Both systems tended to produce more recognizable composites when construction was carried out in the presence of the target compared to its absence. Composites made from memory on the initial trial were marginally better with the CADC System than with Photofit. While both systems showed low absolute accuracy, they enjoyed a measure of success in transmitting a likeness of a facial type. It is concluded that while the CADC system shows promise, psychological constraints upon witnesses' powers of recall may place limits on the absolute accuracy achievable with any system of face reconstruction.These experiments were financed by grant No. POL/73 1675/24/3 from the Police Scientific Development Branch of the U.K. Home Office.

Our gratitude and thanks are due to Tony Kitson and Clive Holloway for their many hours spent developing and operating the CADC system; Jean Shepherd for her skills as a Photofit operator; the Computer-Aided Design Centre; and the MRC Applied Psychology Unit, Cambridge for facilities and subjects.     

Social welfare functions when preferences are convex,strictly monotonic,and continuous

The paper shows that if the class of admissible preference orderings is restricted in a manner appropriate for economic and political models, then Arrow's impossibility theorem for social welfare functions continues to be valid. Specifically if the space of alternatives is R ₊ ⁿ , n ≥ 3, where each dimension represents a different public good and if each person's preferences are restricted to be convex, continuous, and strictly monotonic, then no social welfare function exists that satisfies unanimity, independence of irrelevant alternatives, and nondictatorship.     

A Second Republic for Italy?

Radical change in the representative dimension of Italy's political system was expected to bring a transition to a 'Second Republic' in Italy. That has not happened. Nevertheless, after three consultations using the new parliamentary electoral system, studies focusing on the 'input' side of Italian politics are beginning to agree that substantial change has occurred. It is, however, too early to identify the extent of change in public administration and centre–local government relations, whilst even in parliament it is argued that consensual decision-making continued at least into the late 1990s. The impact of party system change on policy-making has thus been shown to be less direct than many expected, providing rich material for research into the relationship between institutional and policy change. Nevertheless, institutional change continues, particularly with regard to the decentralisation of government, and some studies suggest that this is the key to Italy's political transformation, rather than electoral reform or even change in the form of government. Still, the election of Italy's first right-wing majority government in 2001 may yet bring change in parliamentary practice and policy-making more generally.     

Bureaucracy,Network, or Enterprise? Comparing Models of Governance in Australia,Britain, the Netherlands,and New Zealand

Theories of democratic government traditionally have relied on a model of organization in which officials act impartially, accept clear lines of accountability and supervision, and define their day–to–day activities through rules, procedures, and confined discretion. In the past 10 years, however, a serious challenge to this ideal has been mounted by critics and reformers who favor market, network, or "mixed–economy" models. We assess the extent to which these new models have influenced the work orientations of frontline staff using three alternative service types—corporate, market, and network—to that proposed by the traditional, procedural model of public bureaucracy. Using surveys of frontline officials in four countries where the revolution in ideas has been accompanied by a revolution in methods for organizing government services, we measure the degree to which the new models are operating as service–delivery norms. A new corporate–market hybrid (called "enterprise governance") and a new network type have become significant models for the organization of frontline work in public programs.
