Age calculation using X-ray microfocus computed tomographical scanning of teeth: a pilot study

To correlate dental age with an individual's chronological age based on the calculated volume ratio of pulp versus tooth volume measured, an X-ray microfocus computed tomography unit (microCT) with 25 microm spatial resolution was used to non-destructively scan 43 extracted single root teeth of 25 individuals with well-known chronological age. Custom-made analysis software was used by two examiners to obtain numerical values for pulpal and tooth volume. The ratio of both was calculated and statistically processed. No significant intra- or inter-examiner differences were found. In fact, a very strong concordance correlation coefficient was found. Linear regression analysis showed a coefficient of determination (r) of 0.31 which suggests that there is a rather weak correlation between the volume ratio of pulp versus tooth and biological age. Although rather time consuming, this technique shows promising results for dental age estimation in a non-destructive manner using X-ray microfocus computed tomography.     

The Scandinavian Welfare Model in Crisis? Achievements and Problems of the Danish Welfare State in an Age of Unemployment and Low Growth

The "Scadinavian welfare model" is often considered vulnerable to mass unemployment. The Danish welfare state provides and opportunity to examine the capacities of the "Scandinavian model" to adapt to this situation. This article explores a number of alleged crisis problems of th welfare state, ground into budgetary pressures, incentive problems and legitimacy problems. It is conclude that most of these problems have been exasggerated and that the rrreal threats to the economic foundations of the welfare state should be found in political steering and incentive problems rather thant in the exogenous pressures from the social and economic system, or in pressure from th unintended side effects of welfare arrangement. It is furthermore argued that one of the main achievements of the Danish welfare state has been so prevent unemployment and labor market marginalization from developing into a broad-ranged social marginalizaton and a political po-larization which could undermine citizenship and solidarity in society.     

Transparency and Openness: A Reform or Education Policy?

Current policies are developed through complex and dynamic historical processes and conflicts originating in these processes. In 2002 a new Act on Transparency and Openness in education was put into effect in Denmark. The Act is a formalised system of performance measurement, and introduced a new feature to the governing of the Danish education system. All educational institutions are obliged to publish on the Internet average grades of final examinations. The historical institutional concept of path dependency shows how the outline of the Act is made at an earlier stage. The Act is layered as a new institutional arrangement on top of pre-existing institutions. By focusing on how institutional and political processes interact and are combined, new contributions to historical institutionalism are further developed without considering institutional reproduction and innovation as opposites. It is elaborated how the Act, with respect to certain dimensions, respectively reproduces, breaks with and combines two formerly outlaid paths of education policy and reform policy.     

Tax Structure and Public Spending - Or How the Electorate Is Deceived into Paying for Bigger Public Spending than It Really Wants

It is a classical proposition that tax structure may influence public spending. Two such propositions concerning the visibility and the elasticity of the tax system are tested. Visibility is not important while highly elastic tax systems are correlated with big public spending in times of economic boom. In times of economic decline and recession, high spending countries turn to deficit financing. In both cases big spenders seem to rely more upon a dose of fiscal illusion than moderate spenders.     

Multi-sector cooperation in preventing crime: the case of a South African Neighbourhood Watch as an effective crime prevention model

Abstract

This case study describes the experience of effective and sustainable multi-sector co-operation in the prevention of crime between the Roodekrans Neighbourhood Watch (RNW) in Roodepoort, South Africa, the South African Police Service, private security businesses and the local business sector. This case study is illustrated in the context of empowering communities to take ownership of community safety by facilitating a multi-sector approach. Many studies have highlighted the role of the police in driving crime prevention, however, this paper focuses on the role and contribution of communities themselves as an effective vehicle of crime prevention drawing on multi-sector co-operation. Knowledge regarding best practices in this field of crime prevention remains a work in progress, therefore this paper aims to contribute to the general framework for the growth of successful multi-sector community-based crime prevention initiatives.     

Public sector reform in a poor,aid‐dependent country,Tanzania

African public sectors went through many changes during the 1960s and 1970s in response to political, economic and social pressures. They expanded in size but remained, at least in design, hierarchical and centralized. Their formal relations to society did not undergo any significant changes either. Generally, the reforms now under way are significantly different from earlier ones. Most are inspired by the new public management (NPM) paradigm. They are also much more radical in their aims, among which are: to reduce the core functions of the state; redraw the boundaries between political and administrative responsibilities; emphasize efficiency; redefine relations between public and private sectors; strengthen accountability; reduce corruption; reorganize organizations and staff; change values and attitudes; and exploit new technologies. This article focuses on a paradox of reform in Tanzania: multiple changes are pursued in the public sector despite fragile domestic political support to the reform package as a whole and despite few service delivery improvements on the ground. It is argued that this is the result of substantial external influences, fragmented domestic policy making, weak links between policy making and implementation, and questionable assumptions about some of the key NPM‐inspired reform measures. Moreover, the analyses highlight a number of differences with some of the recent reform literature. Copyright © 2000 John Wiley & Sons, Ltd.
