Communication, in all its aspects excluding advertising, is an intrinsic element in every marketing strategy at whatever level. A quantitative analysis on the adevrtising and communication's feedback may be of absolute importance for the company, the research team and the marketing chief. In...

The notion of solution plays a crucial role in the conceptual system of Léon Walras, the founder of General Equilibrium Theory (GET). In this paper, after introducing the two solution concepts employed by Walras in the development of his version of GET, respectively called the “theoretical”...

In this paper we survey some notions of generalized derivative for C1,1 functions.Furthermore some optimality conditions and numerical methods for nonlinear minimization problems involving C1,1 data are studied.

In public health care organizations, the doctor is not only important as a provider of medical services but also as the individual that determines the demand of medical services; in other words the doctor is both a participant in the definition of demand for services and, at the same time, the...

Research on the transition from school to work is increasingly focusing on the horizontal stratification of educational systems, that is on how different educational tracks have an effect on students’ occupational chances. In the case of tertiary education, this means analyzing how different...

Abstract: Knowledge and technological change or innovation are key drivers of economic growth in the knowledge-based economy (KBE). Although the US economy is traditionally cited as the model, there are other technology frontier examples, such as Canada, arising from strong linkages among firms,...

In this paper some second order necessary and sucient conditions aregiven for unconstrained and constrained optimization problems involving C1functions. A generalized derivative is obtained by approximation with smoothfunctions and it collapses to Clarke's definition when C(1,1) data are...

We investigate the evolution of unionisation, considering both economic and institutional factors.While economists typically study the effects of labour market institutions treating unionisation as given and focusing on rent-seeking motivations, in this paper we study how union membership is...
