Africa is advancing in research and development (R&D) in space with a growing investment in satellites for communications and Earth observations, astronomical observatories, space launch vehicles, and ballistic missiles. These efforts are designed to develop capacity in space science and to advance human development and security in Africa. Nevertheless, there are emerging concerns within and outside the continent on the cost of R&D in space and the public priority it is receiving, given developmental priorities in Africa. This article examines the state of space-related R&D in Africa, its cost and benefits, and the imperative for a balanced policy priority and investment. Leading African states are encouraged to intensify international partnerships, internalize relevant know-how, improve their competitiveness, and support regional initiatives to minimize the domestic cost of spreading benefits of space technology across the continent.  相似文献

A new methodology, Tracking Underreported Financial Flows (TUFF), leverages open-source information on development finance by non-transparent, non-Western donors. If such open-source methods prove to be valid and reliable, they can enhance our understanding of the causes and consequences of development finance from non-transparent donors including, but not limited to, China. But open-source methods face charges of inaccuracy. In this study we create and field-test a replicable ‘ground-truthing’ methodology to verify, update, and improve open-source data with in-person interviews and site visits in Uganda and South Africa. Ground-truthing generally reveals close agreement between open-source data and answers to protocol questions from informants with official roles in the Chinese-funded projects. Our findings suggest that open-source data collection, while limited in knowable ways, can provide a stronger empirical foundation for research on development finance.  相似文献

The Community Reinvestment Act (CRA) encourages bank lending in low- and moderate-income areas. We use a regression discontinuity design that exploits the relative-income threshold that distinguishes CRA-eligible from ineligible neighborhoods (census tracts) and find little evidence that CRA has contributed to neighborhood changes associated with gentrification in eligible areas. Over the 1989–1999 period, we find that eligible tracts had greater increases in mean income relative to ineligible tracts, but we find little evidence that the CRA caused decreases in the proportion of long-term residents or increases in the proportion of White or college-educated residents.  相似文献

African smallholders face few opportunities that can be captured through new technologies alone. Analysis of the institutional context in which they work opens new pathways for innovation. This article synthesises nine studies that attempted such analysis. Using mixed appraisal methods, the studies identify institutional conditions that explain the, often unsatisfactory, outcomes of smallholders, as well as entry points for changing them. Instead of at the farm or community levels, Participatory Innovation System Analysis seeks at higher levels to identify actors, networks and mechanisms that maintain or can change the “pervasive bias against the small farm sector” in SSA.

Défier le « biais omniprésent » à l'encontre des petits cultivateurs africains: identifier les points d'entrée pour les changements institutionnels

Les petits cultivateurs africains ont à leur disposition peu d'opportunités qui puissent être saisies par le seul biais des nouvelles technologies. Une analyse du contexte institutionnel dans lequel ils travaillent ouvre de nouvelles voies pour l'innovation. Cet article synthétise neuf études qui ont tenté une analyse de ce type. À l'aide de méthodes d’évaluation mixtes, les études identifient les conditions institutionnelles qui expliquent les résultats, souvent insatisfaisants, obtenus par les petits cultivateurs, ainsi que les points d'entrée pour les modifier. Au lieu de le faire aux niveaux des exploitations ou des communautés, l'Analyse participative des systèmes d'innovation cherche à identifier à des niveaux supérieurs les acteurs, réseaux et mécanismes qui maintiennent ou peuvent modifier le « biais omniprésent à l'encontre du secteur des petits cultivateurs » en Afrique sub-saharienne.

Cuestionando “el prejuicio persistente” contra los pequeños productores africanos: identificando puntos de abordaje para lograr el cambio institucional

No existen muchas oportunidades de desarrollo dependientes exclusivamente del uso de tecnologías nuevas que puedan ser explotadas por los pequeños productores de África. El análisis del contexto institucional en el que éstos trabajan permite abrir nuevas vías para la innovación. El presente artículo sintetiza nueve estudios que realizaron dicho análisis. A partir del uso de distintos métodos de valoración, dichos estudios identificaron las condiciones institucionales que explican los resultados —a menudo insatisfactorios— obtenidos por los pequeños productores y señalan los puntos de abordaje para mejorar tales resultados. En vez de ser aplicado a nivel de parcela o de comunidad, el Análisis Participativo de Innovación de Sistemas procura identificar a aquellos actores, redes y mecanismos existentes a niveles superiores que pueden mantener o transformar el “perjuicio persistente contra el sector de las pequeñas parcelas” en el África Subsahariana.

Desafiando o “preconceito difundido” contra os pequenos proprietários africanos: identificando portas de entrada para mudança institucional

Os pequenos produtores africanos possuem poucas oportunidades que só podem ser aproveitadas com novas tecnologias. A análise do contexto institucional no qual eles trabalham abre novos caminhos para a inovação. Este artigo sintetiza nove estudos que visaram tal análise. Utilizando métodos de avaliação mistos, os estudos identificam condições institucionais que explicam os resultados, frequentemente insatisfatórios, de pequenos produtores, além de portas de entrada para modificá-los. Em vez dos níveis rurais ou comunitários, a Análise Participativa do Sistema de Inovação busca em níveis mais altos identificar agentes, redes e mecanismos que mantêm ou podem mudar o “preconceito difundido contra o setor dos pequenos produtores rurais” na África Subsaariana.  相似文献

Forensic science laboratories perform analyses on a variety of materials using gas chromatography/mass spectrometry (GC/MS). Instruments from different vendors may be used, requiring analysts to be proficient in the use of multiple proprietary software packages for collecting and processing data. There is no standardized GC/MS software available that can acquire data from different vendors' instruments. However, there are third‐party processing software products that can import data files in different formats. The Centre of Forensic Sciences compared the data processing performance of one such product, ACD/MS Manager Suite, with three instrument vendors' software used for casework analysis. This product was tested for its compatibility with the existing software, its capability to load and present data, and to initiate searches of commercial libraries. The study shows that the MS Manager module provides a means for the forensic analyst to view, process, and report on data from different sources in one software package.  相似文献

This article critically assesses how some public law principles, including the doctrine of legitimate expectations, are applied in the Commonwealth Caribbean. It proceeds to discuss the impact of international law on public law and to note that, through the implementation of unincorporated treaties into domestic law, the principle of dualism is increasingly losing its significance and protective effect. The consequence of this is that Governments will continue to want more opt outs and will be more cautious about signing treaties which they are not ready to implement.  相似文献
