Farming Systems In Southern Mali: How To Improve Small Farmers’ Management Behaviors, Amadou Mamou Kone

Master's Capstone Projects

The study aims at designing a need analysis methodology and a curriculum that deals with the decision making process of small farmers in allocates resources cultural production. The research will be implemented in the Operation H Valley (OHV) and with food crop production. The samples under study concern 33 households 4 different villages.

The focus of study was the actual reactions (behaviors) of farmers in terms of decisions made; actions undertaken and the consequences of the actions with regard to three factors: the input supply system (credit system and extension activities), the market system, and the farmers individual goals and …

Cyclic Gmp May Serve As A Second Messenger In Peptide-Induced Muscle Degeneration In An Insect, Lawrence M. Schwartz, J. W. Truman

Lawrence M. Schwartz

At the end of metamorphosis, the intersegmental muscles of the moth Antheraea polyphemus undergo rapid degeneration in response to the peptide eclosion hormone (EH). Muscle death was preceded by a 22-fold increase in muscle guanosine-3',5'-cyclic monophosphate (cGMP) titers, which peaked 60 min after peptide exposure; adenosine-3'5'-cyclic monophosphate (cAMP) titers remained unchanged. EH induced a dose-dependent increase in muscle cGMP content with a threshold dose similar to that needed to induce cell death. Exogenous cGMP, but not cAMP, mimicked the action of EH. Sodium nitroprusside, a potent stimulator of guanylate cyclase, and methylated xanthines, a class of 3',5'-cyclic-nucleotide phosphodiesterase inhibitors, also …

Forever Young: Upon Reading Growing Young By Ashley Montagu, Raymond Coppinger, Charles Smith

Charles Kay Smith

We argue that the evolutionary process of neoteny -- the natural selection of regulatory gene mutations that retain a youthful ontogenetic system of physiological and behavioral characteristics, and thus never activates the full species-specific features of the ancestors’ adulthood. The resulting new behavio-morph retains infant/young features throughout ontogeny and never displays the adult behavior or physiology of the adult ancestor. This kind of neotenic adulthood defines the human character. We not only inherit our ancestors’ youthful anatomy and physiology but the ancestors’ youthful motivations and proclivities such as docility and social dependency, curiosity and learning as well. We retain our …
