Career experts' conceptions of systems development in lifelong guidance
AbstractThis article reports the findings from a phenomenographic study of career experts’ conceptions of systems development in lifelong guidance settings. The results show that conceptions of systems development in lifelong guidance varied from minimal, aspirational, strategic to systemic. By exploring the logical relationship between qualitatively different conceptions, it provides policymakers and other stakeholders with a way of holistically viewing the varying levels of lifelong guidance systems development. The matrix presented in this article may serve as a catalyst for reflection on crucial elements, such as legislation, leadership and cooperation, that have the potential to improv…
An Investigation into the Stability of Graphitic C 3 N 4 as a Photocatalyst for CO 2 Reduction
The increasing CO 2 concentration in the atmosphere exerts a significant influence on global warming and climate change. The capture and utilization of CO 2 by conversion to useful products is an area of active research. In this work, the photodriven reduction of CO 2 was investigated using graphitic carbon nitride (g-C 3 N 4 ) as a potential photocatalyst. The photocatalytic reduction of CO 2 was investigated with g-C 3 N 4 powder immobilized on a glass support in a batch gas-phase photoreactor. The experiments were carried out under UV-vis irradiation at 70 °C and an initial pressure of 2.5 bar. The only gas-phase product detected during the irradiation of the g-C 3 N 4 in the presence of…
