Through the use of low dosages chemical fertilizers and effective nutrient-corn genotypes that respond to bio-fertilizer type assignments, this study intends produce rather steady outcomes over course several growing seasons. Field tests for have been conducted at ATP Ministry Research Technology in South Sumatra. The experiment was run across two seasons: dry season (May through September 2011...

In this study, primary and immortalized bovine intestinal epithelial cells (BIECs) were characterized for the expression of surface carbohydrate moieties. Primary BIEC-c4 showed staining greater than 90 % 16 lectins but less 50 four lectins. Immortalized BIECs significantly different lectin binding profile few compared to cells. studied infectivity E. coli, Salmonella enterica, rotavirus, coron...

A two-phase field experiment on the effect of N application was studied on growth, yield and quality of seed cane of sugarcane variety, B41/227 at Finchaa Sugarcane Plantation during 2000/2001 and 2002/2003 cropping years. Thirty two treatments comprised of four N levels – 0, 46, 92 and 138kg/ha, and applied at 2 1 /2, 5 and 7 1 /2 months after planting in whole and split applications were used...

This text is to appear in a volume produced at the occasion of the 100th anniversary of Léon Walras death. The first part (introduction) answers one initial demand (to the solicited authors), i.e the evaluation of Walras influence on their own research and more generally on contemporary research. The second part “Between the Capitol Hill and the Tarpeian Rock ? ” goes further into the discussio...

A large market economy has a huge number of degrees of freedom with weak microlevel coordination. The ‘implicit microfoundations’ approach considers this property of micro-level interactions to more strongly determine macro-level outcomes compared to the precise details of individual choice behavior; that is, the ‘particle’ nature of individuals dominates their ‘mechanical’ nature. So rather th...

Whitman argues that group selection is consistent with methodological individualism. He begins by defining a weak form of methodological individualism in which agents are not necessarily self-interested or rational and shows that this form of is consistent with Sober and Wilson’s model of group selection. However, Sober and Wilson’s group selection is also consistent with a methodological indiv...

In this paper we report the results of a laboratory experiment, in which we observed the behavior of agents in a simple macroeconomic setting. The structure of the economy was only partially known to the players which is a realistic feature of our experiment. We investigate whether subjects manage to approach optimal behavior even if they lack important information. Furthermore, we analyze subj...

Static neoclassical framework cannot be applied to model time dependent processes or increasing returns to scale in production. The dynamization of the neoclassical theory of a firm by dynamic optimization, on the other hand, assumes inconsistent profit functions with the former. As a solution to these problems, we present a dynamic theory of a firm consistent with the static neoclassical theor...

We examine the Cournot oligopoly model in the context of social and individual learning. In both models of learning, firms update their decisions about how much to produce via variants of the genetic algorithm updating procedure. Arifovic (1994) found that both models of social and individual learning converged to the Walrasian, competitive equilibrium. Vriend (2000) reports that the model of s...

We review and evaluate some recent contributions on modeling entrepreneurship within a neoclassical framework, analyzing how and to what extent the fundamental ingredients suggested in the social science literature were captured. We show how these approaches are important in stressing the main elements of a complex picture without being able to fully describe it. Each modeling attempt focuses o...
