Extending a Life with Meaning

This essay questions Callahan’s criticism of people’s aspiration to extend their life. It argues that ideas about life are subject to historical variations and the question at issue is whether society can give meaning to aging. It also questions the claim that the radical extension of human life will jeopardize the welfare of future generations. It suggests that the application of the precautionary principle to the question of aging avoid facing up to question how society should value the old.

Punctuated Equilibrium in Comparative Perspective

We explore the impact of institutional design on the distribution of changes in outputs of governmental processes in the United States, Belgium, and Denmark. Using comprehensive indicators of governmental actions over several decades, we show that in each country the level of institutional friction increases as we look at processes further along the policy cycle. Assessing multiple policymaking institutions in each country allows us to control for the nature of the policy inputs, as all the institutions we consider cover the full range of social and political issues in the country. We find that all distributions exhibit high kurtosis values, significantly higher than the Normal distribution which would be expected if changes in government attention and activities were proportionate to changes in social inputs. Further, in each country, those institutions that impose higher decision-making costs show progressively higher kurtosis values. The results suggest general patterns that we hypothesize to be related to boundedly rational behavior in a complex social environment.

Access and coverage: which farmers do plant clinics reach in Uganda?

This article reports on a study that assessed farmers’ access to, and coverage of, five plant clinics operating from market places in two districts of Uganda. Despite the noticeable geographic and thematic coverage of the services, placing plant clinics at markets did not automatically ensure equitable access and high farmer attendance. Clinic users were predominantly middle-aged male farmers and overall attendance was relatively low. Uganda has taken plant clinics to scale in recent years due to their potential to strengthen the country’s responsiveness to pests and diseases. Optimising farmer reach and ensuring equity in access requires reviewing clinic placement, timing, and mobilisation strategies.
