The importance of networking as a way to enhance innovation has been pointed out in many scientific papers, in particular for SMEs. A great number of scientific studies clearly establish the significant role of SMEs in economic growth, promoting flexibility and innovation in an economy. The...

The aim of the paper is to analyse value sharing and food system dynamics of milk, tomato, and cereals food chains, so to explore the agro‐food enterprises capacity to be competitive and sustainable. The paper is based on the functionalist approach of Malassis and the notion of the system of...

debate on appropriate framework, tools and methods to evaluate food and feed along the chains. This paper presents literature review for evaluation of triple bottom line impacts of soy and beef chains in particular, and food chains in general. We reviewed literature on the sustainability of soy...

The problem of simultaneously identifying and controlling a time-varying, perfectly-observed linear system is posed. The parameters are assumed to obey a Markov structure and are estimated with a Kalman filter. The problem can be solved conceptually by dynamic programming, but even with a...

A recursive algorithm for estimating linear models with both constant and time-varying parameters is derived by maximization of a likelihood function. Recursive formulas are also derived for derivatives of the likelihood function; the derivatives are needed for numerical evaluation of some...
