The “impulsivity index”: Its application to juvenile delinquency

An objective, composite index of impulsivity, made up of three measures of reactivity to color on the Rorschach and amount of discrepancy between performance and verbal IQ on the Wechsler Scales, is proposed. It was predicted that impulsiveness as measured by this index would be associated with self-perception of impulsivity. Moreover, it was predicted that impulsiveness, whether objectively or subjectively measured, would tend to be associated with a history of greater and more frequent delinquency. The major hypotheses were confirmed. In addition, the data suggested that delinquents from higher socioeconomic levels may be more impulsive than their lower class counterparts. Additional work on refining and validating the impulsivity index is indicated.This work has been supported by Grant No. A70-15 from the Illinois Law Enforcement Commission.Currently a Ph.D. Candidate in Human Development at the University of Chicago.

An analysis of voter predictive dimensions and recovery of the underlying issue space

Based on the spatial voting model posited by Enelow and Hinich, this paper presents a means of determining the nature of the issue dimensions used by voters. This method allows for calculation of the extent to which the predictive dimensions recover the underlying issues space. Of particular interest is the extent to which a single predictive dimension can recover the issue space. The method also suggests that Enelow and Hinich are correct in their hypothesis that the social liberal-conservative axis and the economic liberal-conservative axis are the dimensions most used by the electorate.     

Seeing eye to eye: organizational behaviour,brokering and building trust in Tanzania

The focus of this article is organizational behaviour in and around the private sector in Tanzania at a time of transition through liberalization and the promotion of private sector activity; how the private sector has re‐emerged in the very recent past; how it operates as a group or, more accurately, as a set of groups, and the relationships between its component parts and with other development organizations (notably public actors: the state and aid donors). Within this framework our interest is in how organizational behaviour is mediated and trust is built through the brokering of relations between different organizations which intersect the public and private (and what this means for the public sphere). The article assesses the usefulness of a three‐level framework for analysing organizational and institutional transformation, shows that some tentative but modest change is occurring, and that a range of incomplete but positive political processes are happening. We show that institutional development is the weak link in these processes. Copyright © 2002 John Wiley & Sons, Ltd.     

Polycentric Governance and Irrigation Reform in Kenya

In Kenya, as in many developing countries, centralized control over water resources was implemented to improve agricultural productivity. By the 1980s, however, Kenya's postindependence policies of bureaucratic control were in disarray, and conflicts over water use were common. More recently, Kenya has embarked on a series of reforms that create a polycentric approach to water governance, in which decision making about water resources is shared among multiple, overlapping local, regional, and national authorities. Drawing on archival and field research, we examine these reforms in their historic context and argue that whereas centralized control was poorly adapted to the Kenyan context, polycentric governance is better suited to Kenya's variable social and ecological conditions and the available resources of its administrative agencies.     

ADMINISTRATIVE REFORM AND ECONOMIC DEVELOPMENT: CONCEPTS, ISSUES, AND THE NATIONAL EXPERIENCE

This symposium examines issues related to the links between administrative reform policy and economic development policy. The symposium introduction paper consists of two parts. First, it offers an overview of the background of theoretical and conceptual issues that are important to the connection between administrative reform and economic development. The issues reviewed include the role of government in economic development, the importance of public policy and management to economic development, the contribution of development administration, and the need of administrative reform to remove bureaucratic problems and promote efficiency. Next, the introduction paper provides a brief summary of the research arguments and findings addressed in the following six articles. They include an evaluation of administrative reform in Arab world economic growth, an examination of administrative reform and economic development in Latin America and the Caribbean, a political economy analysis of policy reform in Korea, a study of the implementation of privatization strategies in India's public sector reform, a discussion of the concerns between efficiency and ethics in China's economic development, and the study of administrative and economic development in Mongolia. The implications of the research findings and the need for further study of the linkage between administrative reform and economic development are emphasized in the conclusion.

Modification of the Marmarou and Foda model of diffuse axonal injury (DAI) improves percentage survival of rats at 24 h and increases the amount of DAI identified

More than two decades ago, Marmarou published a valid model for producing diffuse axonal injury (DAI) in rats. Since then, both mild and severe injuries have been obtained by researchers using the original method and a weight of 450 g. However, the diffuse brain injuries produced in rats were only similar to those seen in humans when the rats sustained severe brain injuries. In these cases, rat mortality in the original article was around 50%, and the cause of death was prolonged apnea post-impact. Rat survival after impact is critical for studying the progression of DAI. In order to explain the cause of death in human victims with cranial trauma who do not show gross brain injury, testing for the presence of DAI is essential. Thus, in order to minimize local and cervical injuries to increase rat survival, attention should be paid to the following aspects: a wider head protector disc should be used, the head of the rat should be elevated at the time of impact, and the foam bed should be soft enough to allow the movement caused by acceleration. With our modified method, rat survival increased by 30% compared to the original model (80% versus 50%). Moreover, 85.7% of rats demonstrated DAI after 24 h of survival. With these modifications, injuries appear in the same locations as in humans; thus, the method is suitable for the study of traumatic DAI in humans.
