Governing the Borderlands: Decoding the Power of Aid

This article examines aid practice, that is, the public-private contractual networks that link donor governments, UN agencies, military establishments, NGOs, private companies and others, as a relation of global liberal governance. In order to fulfil this function, such networks embody what could be called the 'securitisation' of international assistance. Based upon ideas of human security and ameliorating the effects of poverty and vulnerability reduction, aid is now seen as playing a direct security role. Rather than being concerned with relations between states, the primary aim of this security paradigm is to modulate and change the behaviour of populations within them. In doing so, it is able to exploit the opportunities afforded by privatisation. At the same time, however, aid as security is confronted by its own particular problem of 'governing at a distance'; how can calculations made by leading states be transformed into actions at the global edge when a multitude of private and non-government implementors now intervene? The article concludes by examining the contribution of risk analysis to solving this problem and, especially, the development of new contractual regimes based around technical standardisation, benchmarking and performance auditing. Through such technologies, metropolitan states are learning how to manage the public-private networks of aid practice and, as a result, to govern the borderlands in new ways.

Dangerous chemicals

Council Regulation (EEC) No 2455/92 has been adopted by the Council of the European Communities, in 1992, to improve information exchange on certain dangerous chemicals with third countries, particularly developing countries. To implement the notification procedure in accordance with the Regulation, a database has been developed to manage and simplify the procedure. The software exists in three versions; one adapted for use by the Designated Authorities of the Member States, another for the European Chemicals Bureau (ECB) and the third one is an information version aimed at Designated National Authorities outside the European Union and Industry. The database “EDEXIM” is currently working in a PC environment and is being developed as an on-line system with a stand-alone client/server architecture.     

AUBURN DAM: A CASE STUDY OF WATER POLICY AND ECONOMICS1

ABSTRACT: This paper provides a critical analysis of the Bureau of Reclamation's Auburn-Folsom South project in California. While this massive $1.5 billion project is temporarily halted for redesign for earthquake hazard, it is timely to examine its justification on economic grounds. The key finding is that several major benefit categories, irrigation and recreation, have been grossly overstated. In addition, the Bureau failed entirely to estimate the cost of use on the free-flowing American River, or a probability-weighted estimate of catastrophic loss. Revised estimates indicate that the project is not economically justified. In addition, the project has unattractive distributive effects. The implications of this case study for current revisions in U.S. water policy are explored. The Auburn study basically provides support for the U.S. Water Resource Council's draft manual of procedures for evaluating federal water resource projects.     

Valuation of National Park System Visitation: The Efficient Use of Count Data Models, Meta-Analysis, and Secondary Visitor Survey Data

The National Park Service (NPS) currently manages a large and diverse system of park units nationwide which received an estimated 279 million recreational visits in 2011. This article uses park visitor data collected by the NPS Visitor Services Project to estimate a consistent set of count data travel cost models of park visitor willingness to pay (WTP). Models were estimated using 58 different park unit survey datasets. WTP estimates for these 58 park surveys were used within a meta-regression analysis model to predict average and total WTP for NPS recreational visitation system-wide. Estimated WTP per NPS visit in 2011 averaged $102 system-wide, and ranged across park units from $67 to $288. Total 2011 visitor WTP for the NPS system is estimated at $28.5 billion with a 95% confidence interval of $19.7–$43.1 billion. The estimation of a meta-regression model using consistently collected data and identical specification of visitor WTP models greatly reduces problems common to meta-regression models, including sample selection bias, primary data heterogeneity, and heteroskedasticity, as well as some aspects of panel effects. The article provides the first estimate of total annual NPS visitor WTP within the literature directly based on NPS visitor survey data.     

Speciation and the bioavailability of actinide elements

A good understanding of the quantitative uptake of actinide elements from foodstuffs, across the mucosal cell membranes of the gastrointestinal tract, into man is of great importance in setting intake limits and in assessing radiation doses to critical organs.

In the past, such knowledge has been gained from the extrapolation of animal models to man. Whilst this strategy has proved useful in a number of cases, it is, unfortunately, phenomenological and the results prone to perturbation from factors such as the fasting state of the animal and the initial chemical form of the actinide.

The application of computer simulation models which can calculate the chemical speciation of an element in a variety of foodstuffs under conditions pertinent to the gastrointestinal tract offers a non‐invasive and general method for predicting the uptake of exogenous elements, like the actinides.

This paper reviews the current state of chemical speciation analysis with respect to bioavailability highlighting areas requiring further consideration, presenting results amplifying the issues raised and showing that computer simulation has a rôle to play in predicting quantitative uptake of the actinides.     

Convergent validity between willingness to pay elicitation methods: an application to Grand Canyon whitewater boaters

We directly compare trip willingness to pay (WTP) values between dichotomous choice contingent valuation (DCCV) and discrete choice experiment (DCE) stated preference surveys of private party Grand Canyon whitewater boaters. The consistency of DCCV and DCE estimates is debated in the literature, and this study contributes to the body of work comparing the methods. Comparisons were made of mean WTP estimates for four hypothetical Colorado River flow-level scenarios. Boaters were found to most highly value mid-range flows, with very low and very high flows eliciting lower WTP estimates across both DCE and DCCV surveys. Mean WTP precision was estimated through simulation. No statistically significant differences were detected between the two methods at three of the four hypothetical flow levels.     

From emergency to social security in Sudan - part I: the problem

This is the first part of a two-part article which stresses the need to move away from short term emergency measures to a more general system of social security. A weakness in much of the thinking on food security in Sudan is its conception of a normally self-provisioning peasantry which is pushed into distress only as a consequence of exceptional external conditions. Food catastrophes are therefore seen as, essentially, temporary phenomena requiring emergency interventions. This article proposes a different view: that the commercial development of Sudan has engendered a crisis of subsistence synonymous with the collapse of indigenous support systems, the spread of absolute poverty and the erosion of the country's resource base. In the North this situation has come about through economic means and in the South through war. The spread of absolute poverty and the resulting vicious struggle for scarce resources cannot, however, be separated from the decay in governance. Part I of the article attempts to establish the interconnections between these elements and thereby to indicate the problems which a system of social security would have to overcome. Part II will examine the institutional consequences of the crisis, namely the imposition of a donor-led system of social security.
