The role of the courts in certain educational policy formation

A study of recent court decisions indicates that courts tend to decide cases in education with apparently little or no citation in their opinions of the findings of research studies in the fields of education, economics, psychology, sociology, etc. This may be unique since the courts seem to be more liberal in other areas of the law where inputs from other disciplines (e.g. medicine) are cited and do find their way into the decisions of cases. The implications of this for educational policy formation and educational research need to be more thoroughly examined.This study merely describes a finding and does not purport to state a position or to offer suggestions for a future course of action.     

Institutional boundaries and common‐pool resource management: A comparative analysis of water management programs in California

Policymakers and academics often identify institutional boundaries as one of the factors that shape the capacity of jurisdictions to manage natural resources such as water, forests, and scenic lands. This article examines two key bodies of literature—common‐pool resource management theory and local public economy theory—to explain how the boundaries of political jurisdictions affect natural resource management. Two empirical methods were used to test hypotheses from the literature, using a study of water management programs in California. The results demonstrate that institutional boundaries that coincide with natural resources are likely to be associated with the implementation of more effective resource management programs. At the same time, where jurisdictions can control through coordination, they can also facilitate more effective resource management where jurisdictions do not match resource boundaries. © 2004 by the Association for Public Policy Analysis and Management.     

Aquinas's Two Doctrines of Natural Law

This paper examines the role which the concept of natural law has to play in the political thought of Aquinas, as this is to be found in the Summa Theologiae . It focuses particularly on Aquinas's understanding of the relationship which exists between natural and positive law. It argues that Aquinas's views are inconsistent and that the Summa actually contains two quite different positions regarding this subject. One of these is inherited from the Stoic natural law tradition and the other from Aristotle. The former considers natural law to be a critical standard by means of which positive law can be evaluated by individuals, whereas the latter does not. On the contrary, it maintains that according to Aquinas the principles of natural law require interpretation, and that this interpretation is to be provided, not by the conscience of the individual moral agent, but by positive law. Focus on either one or the other of these two documents leads to quite different interpretations of Aquinas's political thought as a whole. One such interpretation sees Aquinas as being a distant forerunner of the liberal political tradition. The other associates Aquinas much more closely with the notion of authority and hence with conservatism in politics. The article concludes by commenting on the relevance of these different interpretations of Aquinas for the contemporary debate between liberals and communitarians.     

Influencing Public Opinion of Space Policy: Programmatic Effects Versus Education Effects

The public is generally supportive of space policy, but less supportive of spending for the National Aeronautics and Space Administration (NASA) compared to other government programs. Previous research has helped identify who is more likely to be supportive of NASA spending, but not why. This study seeks to understand the causal mechanisms that influence support for NASA. Using natural between-survey and induced within-survey experiments, this study attempts to identify factors influencing changes in public support for NASA spending. Short-term programmatic and related media effects appear to have no influence on public support for NASA spending. However, correcting information asymmetries in regard to NASA's budget appears to have a significant positive effect on public support for NASA spending. The findings speak to the importance of the public being well informed on policy issues in order to make a correct policy choice, and demonstrate that individual programmatic aspects may not be as important as overall agency direction.     

Global Justice and the Distribution of Natural Resources

What should a political theorist say about the justice of the global distribution of natural resources? One issue is whether principles of distributive justice should be applied globally, and this has been debated between nationalists and cosmopolitans. A second, though, is how the category of 'natural resources' should be conceived in relation to other distributable goods. This has not adequately been addressed even by theorists of global justice who expressly focus on natural resources. In particular, neither Charles Beitz's argument for a natural resources redistribution principle nor David Miller's argument against works with a satisfactory account of how the physical distribution of resources relates to the distribution of their economic value. A more satisfactory account can be developed from the perspective of ecological economics as inspired by Nicholas Georgescu-Roegen. From this perspective, global inequalities in the command of natural resources can be viewed with the clarity that a normative theory of their justice requires. If natural resources are re-conceptualised in terms of 'ecological space', Beitz's argument can be recast and vindicated. The re-conceptualisation is necessary to overcome the problems with the original version, as is shown by reference to the existing alternative formulations of Hillel Steiner and Thomas Pogge.     

Come hell or high water: An investigation of the effects of a natural disaster on a local election

How is electoral support for incumbent candidates shaped by natural disasters? Do voters in districts newly recovering from a national disaster punish or reward incumbents for their response to the disaster when compared to their counterparts in unaffected districts? The City of Calgary is used here as a case study. On 20 June 2013, the Bow and Elbow rivers flooded in the Calgary, devastating 26 neighborhoods and displacing approximately 75,000 people, or 7 per cent of the city's population. Four months later, a municipal election was held. When analyzed as a natural experiment, results suggest that support for the incumbent mayor increased city-wide between the 2010 and the 2013 elections, but at a lower rate in areas that experienced residential flooding. However, the flood did not produce equivalent treatment and control groups, as flooded areas differ systematically from areas that were not flooded in ways key to the election outcome. When analyzed more conservatively, results show that the flood had no effect on incumbent support or voter turnout. Thus, this disaster introduces a note of caution into the literature examining the effects of natural disasters on electoral behavior.     

Technical Management in an Age of Openness: The Political,Public, and Environmental Forest Ranger

Modern bureaucracy faces trade‐offs between public and congressional input and agency expertise. The U.S. Forest Service offers an opportunity to quantitatively analyze whether an agency that is required to be more open to the public and congressional input will be forced to ignore its technical expertise in managing resources. This study uses data on 83,000 hazardous fuels reduction activities conducted by the Forest Service from 2001 to 2011. Although the results show that managers are responsive to public and congressional considerations, this has not prevented them from utilizing their technical knowledge to restore lands most deviated from natural conditions. This suggests that managers can balance responsiveness to public and political principals with technically sound management.

Deregulation redux: does mandating access to bottleneck facilities necessarily improve welfare?

We demonstrate that deregulation in the form of vertical separation of network components into natural monopoly and potentially competitive markets does not truly represent a lessening of regulatory burdens. That is, vertical separation is not synonymous with deregulation; “more competitors” is not equivalent to “more competition”. We assume a public interest regulator that is constrained to set a unit price that maximizes expected welfare subject to a break-even constraint. We show that under both symmetric and asymmetric information cases the information demands on the regulator of the vertically integrated system are no greater than those in the case of vertical separation.
