High value crop products and rural prosperity: The role of operations research and analytics by Cock, James H, Jimenez, Daniel R

“…Moreover, the complexity of agriculture with multiple interactions between factors makes it nigh on impossible to obtain information on all the variables that might be important. Operations Research, which looks at an organization’s operations and uses mathematical or computer models, or other analytical approaches, to find better ways of doing things, overcomes many of the limitations of the traditional research methods. …”

Co-infections determine patterns of mortality in a population exposed to parasite infection by Woolhouse, Mark E.J., Thumbi, Samuel M., Jennings, A., Chase-Topping, M., Callaby, R., Kiara, Henry K., Oosthuizen, M.C., Mbole-Kariuki, Mary N., Conradie, I., Handel, Ian G., Poole, Elizabeth J., Njiiri, E., Collins, N.E., Murray, G., Tapio, M., Auguet, O.T., Weir, W., Morrison, W. Ivan, Kruuk, L.E.B., Bronsvoort, B.M. de C., Hanotte, Olivier H., Coetzer, K., Toye, Philip G.

“…Across our study population, this corresponds to a net reduction in mortality due to ECF of greater than 40%. Using a mathematical model, we demonstrate that this degree of heterologous protection provides a unifying explanation for apparently disparate epidemiological patterns: variable disease-induced mortality rates, age-mortality profiles, weak correlations between the incidence of infection and disease (known as endemic stability), and poor efficacy of interventions that reduce exposure to multiple parasite species. …”
