The continuing need for affirmative action

Affirmative action is defined as the steps taken to end the absence in jobs, schools, and honored positions of members of groups that have been subordinated. Its purpose is to reduce discrimination, to reduce income disparities between groups, and to promote diversity by gender and race in every role and activity. The persistence of occupational segregation by sex and race to a degree that cannot be explained by differences in qualifications or voluntary behavior testifies to the need for further action. Alternatives to affirmative action, such as helping people regardless of race or sex from disadvantaged backgrounds, “just enforcing the law against discrimination”, or waiting for educational improvements to bring groups better qualifications would not do the job affirmative action is designed to do.     

Bond immunization for additive interest rate shocks

This paper explores bond immunization for additive term structure models. This class of term structures contains many models that are commonly used in the duration and immunization literature. We establish the necessary and sufficient conditions for immunization and prove the existence of a bond portfolio that satisfies the immunization condition. Based upon the immunization condition, we develop a general definition of duration that applies to any additives term structure model.     

SUGGESTIONS ON REBUILDING CATHOLIC SOCIAL TEACHING ON ECONOMICS

A question hangs over the authoritative status of what has come to be called Catholic Social Teaching. The recent publication of the Compendium of the Social Doctrine of the Church gives added point to this question. This paper sketches the elements that should inform a genuinely authoritative Catholic teaching on this subject, based on the foundational principles of Catholic moral theology. The most recent encyclical in this area, Benedict XVI's Caritas in Veritate , is analysed.     

Site selection to test an integrated approach to agricultural research for development: combining expert knowledge and participatory Geographic Information System methods

The sub-Saharan Africa challenge programme is designed to address the problems of failures of agricultural markets, inappropriate policies and natural resource degradation, that contribute to the continuing deterioration of livelihoods and food security in the region. It is seeking to do this by redefining the roles of scientists and farmers through collaborative learning processes, addressing questions about the level, timing, type and formof participation, as well as themost effective approaches andmethods to foster them. The research domains of the programme deal with sustainable intensification of smallholder agriculture, the sustainable management of natural resources, the development of efficient markets, and the promotion of enabling policies. One question that was addressed in designing the initiative was deciding where to work so as to maximize the chances of successful testing of this new approach, so that it would lead to significant reductions of rural poverty. A participatory process was put in place to design a framework to accomplish this site selection, and then to apply it in west, east and southern Africa. A mixture of spatial data analysis and expert knowledge on spatial and non-spatial factors was used, and one primary site in each region was identified to form the basis for the next phase of the challenge programme. Several lessons were learnt from the process, including the importance of adapting themethods to actual conditions, the increased utility of targetting when the quantitative and the qualitative are freely combined, and the continued need for baseline spatial and non-spatial data to improve the targeting of research in the future that is designed to alleviate poverty in sub-Saharan Africa.
