Aids Pandemic

The new millennium sees the largest cohort of young people in history entering its fertile years. Many of these people are too poor to pay the full cost of modern contraception, but the money available for subsidizing their needs is exceedingly limited. The AIDS pandemic is placing additional, unprecedented demand on already overstretched resources. Existing methods of contraception that are well established and off-patent can be produced in bulk at low cost, and will remain the backbone of future programmes. The use of misoprostol as an abortifacient is likely to spread rapidly. New methods must take into account the limitations of the health infrastructure in developing countries and the imperative of low cost. Given the constraints of money, skills and facilities, it is essential to set realistic priorities for future contraceptive research and development. It is suggested that the greatest needs are for a woman-controlled method of preventing HIV transmission and for a non-surgical method of female sterilization.

The Impact

The New Zealand dairy industry recognises that to remain competitive it must continue to invest in research and development. Outcomes from research have ensured year-round provision of low-cost feed from pasture while improving productivity. Some of these advances, discussed in this paper, include the use of white clover in pasture, understanding the impacts of grass endophyte, improved dairy cow nutrition, the use of alternative forage species and nitrogen fertiliser to improve productivity, demonstration of the impact of days-in-milk on profitability, and the use of feed budgeting and appropriate pasture management.

An estimated 80 % of all illnesses in developing countries is in one way or another related to water. In order to alleviate this most serious condition, the united Nations has initiated the “International Water Decade”, for which the estimated costs are $600 000 million, a sum which is far beyond any available means. By application of “low-cost technology” this sum could be reduced to $100 000 million which brings the objective within the reach of possibility. Details are given of the design and methods of construction of units which are best suited to the specific requirements and which would be simple, reliable and economical to operate. These can be constructed largely from local materials and by local labour. The need for appropriate training of both operators and the user population is stressed.

AbstractGreat efforts are devoted to end the HIV epidemic as it continues to have profound public health consequences in the United States and throughout the world, and new interventions and strategies are continuously needed. The use of HIV sequence data to infer transmission networks holds much promise to direct public heath interventions where they are most needed. As these new methods are being implemented, evaluating their benefits is essential. In this paper, we recognize challenges associated with such evaluation, and make the case that overcoming these challenges is key to the use of HIV sequence data in routine public health actions to disrupt HIV transmission networks.

Testing of untethered subscale models, often referred to as subscale flight testing, has traditionally had a relatively minor, yet relevant use in aeronautical research and development. As recent advances in electronics, rapid prototyping and unmanned-vehicle technologies expand its capabilities and lower its cost, this experimental method is seeing growing interest across academia and the industry. However, subscale models cannot meet all similarity conditions required for simulating full-scale flight. This leads to a variety of approaches to scaling and to other alternative applications. Through a literature review and analysis of different scaling strategies, this study presents an overall picture of how subscale flight testing has been used in recent years and synthesises its main issues and practical limitations. Results show that, while the estimation of full-scale characteristics is still an interesting application within certain flight conditions, subscale models are progressively taking a broader role as low-cost technology-testing platforms with relaxed similarity constraints. Different approaches to tackle the identified practical challenges, implemented both by the authors and by other organisations, are discussed and evaluated through flight experiments.

Benefit Cost

Abstract The question of how to allocate scarce agricultural research and development dollars is significant for developing countries. Historically, benefit/cost analysis has been the standard for comparing the relative benefits of alternative investments. We examine the potential of shifting the implicit equal weights approach to benefit/cost analysis, as well as how a systematic variation in welfare weights may affect different groups important to policy makers. For example, in the case of Rwandan coffee, a shift in the welfare weights that would favor small coffee producers in Rwanda over foreign consumers of Rwandan coffee would increase the support for investments in small producer coffee projects. Generally, changes in welfare weights alter the ordering for selecting investments across alternative projects.

Important Cash Crop

Potatoes are an important cash crop for small-scale producers worldwide. The move away from subsistence to commercialized farming, combined with the rapid growth in demand for processed agricultural products in developing countries, implies that small-scale farmers and researchers alike must begin to respond to these market changes and consider post-harvest treatment as a critical aspect of the potato farming system. This paper presents and assesses a low cost potato-grading machine that was designed explicitly to enable small-scale potato growers to sort tubers by size for supply to commercial processors. The results of ten experiments reveal that the machine achieves an accuracy of sort similar to commercially available graders. The machine, which uses parallel conical rollers, has the capacity to grade different tuber shapes and to adjust sorting classes, making it suitable for locations with high potato diversity. Its relatively low cost suggests that an improved and adapted version of this machine might enhance market integration of small-scale potato producers not only in Peru, but in other developing countries as well.

Intellectual Challenge

The UN commitment to achieving the Millennium Development Goals (MDGs) by 2015 poses a major challenge. It is, first and foremost, a political challenge to wealthy countries, to provide the necessary transfer of resources, and to developing countries, to make effective use of these transfers. But it is also an intellectual challenge, to economists and other scientists, to better understand the processes by which the MDGs can be achieved. This article focuses on two aspects. On the substantive side, it examines how we can achieve increased funding for development, particularly via new methods of finance, such as global taxes. On the intellectual side, it describes how a new branch of economics is developing – global public finance – that can contribute to the analysis of new sources of funding for the MDGs and of the working of the global economy.
