he purpose of this paper is to explore the relationship between the use of ICT, the accumulation of e-skills and innovation capacities of teachers. A Web questionnaire was designed in order to examine the e-skills and the daily practices of vocational high-school teachers in Tunisia. The results...

This paper suggests a modelling of the labelling procedure consistent with empirical observations, that allows the endogenous calculation of labelling criteria. The authority in charge of the labelling program chooses the level of labelling criteria so as to maximise the social surplus,...

We investigate the existence of causal relationships between energy consumption and education (enrollment in primary secondary and higher education) for a sample of 16 African countries over the period 1971-2010 (according to availability of countries' data). We use the panel-data approach of...

This article extends the recent findings of Liu (2005), Ang (2007), Apergis et al. (2009) and Payne (2010) by implementing recent bootstrap panel unit root tests and cointegration techniques to investigate the relationship between carbon dioxide emissions, energy consumption, and real GDP for 12...

Using a bootstrap panel analysis that allows for cross-country dependence, without requiring the use of pre-tests for a unit root, we study the causality links between energy use and employment for a sample of 16 African countries over the 1991-2010 period (according to availability of...

We make use of a bootstrap panel analysis of causality between energy use and economic growth for a sample of sixteen African countries over the period 1988-2010. Our results show that growth and energy use are strongly linked in Africa. However, African countries are heterogeneous and there is...

The analysis of the main determinants of intra-firm diffusion of digital technologies is becoming in the focus of attention. However, there is a lack of empirical research, particularly in Europe. This paper proposes a specific approach to modelling intra-firm diffusion process by combining the...
