Bestrijding van Phoma in Sedum

In het gewas Sedum kan de schimmel Phoma telephii veel schade aanrichten. Phoma kan als een sluipmoordenaar in het gewas te gaan werken en is in staat om het gehele gewas te vernietigen als niet direct een goede bestrijding van de schimmel wordt uitgevoerd. Omdat de toelating van het middel Topsin M is ingetrokken, is gezocht naar nieuwe middelen voor de bestrijding van deze hardnekkige schimmel in de bloementeelt van Sedum

Educating "Modern Mind" in the Light of the Evolution of Western Educational Thought

My thesis is that liberal and progressive education models respectively refer to dual and unitary conceptions of intellectual development, and that these differences account for their pedagogical antagonisms. I test the validity of this argument by using it to account for the evolution of Western pedagogy and the fate of liberal and progressive education. I introduce the dualist epistemological premises of the major educational models that have followed one after the other in the history of Western education. Then, I account for the impact of classical empiricism, and later evolutionary doctrines, on the discredit of liberal education and the emergence of educational progressivism. Progressive educational conceptions are rooted in a representation of humankind developed under the influence of the Darwinian revolution. They justify an adaptive model of the mind within the framework of a functionalist psychology. According to alternative currents of modern educational thought, the use of auxiliary means of thought marks a rupture with human biological development. These currents underpin a dual conception of human reason according to which rational or theoretical understanding is a sui generis dimension of thought. They offer support for a modernized version of liberal education

Interventions for Mitigating Drought-Related Livestock Mortality in Africa’s Pastoral Areas: A Review of Their Relevance and Effectiveness with Special Reference to Kenya

One of the key challenges facing pastoral livestock production in Africa’s drylands is the recurring drought which triggers shortage of grazing resources and massive losses of livestock. Though the pastoralists have traditional drought coping mechanisms, the changing land use, insecure land-tenure arrangements, and the declining natural resource base, have undermined the effectiveness of the mechanisms and worsen the drought impacts. Several interventions have hence been implemented over the years to mitigate the increasing drought impacts and to create more resilient pastoralist societies. Focusing on Kenyan pastoral areas, this study reviewed the relevance and effectiveness of various interventions in reducing the drought-related livestock mortalities. The results show that drought interventions such as destocking programs, supplementary feeding, provision of early warning information, water development, and veterinary services were commonly implemented, but often at the late stage of drought cycles with little emphasis on sustainability
