An adult life cycle perspective on public subsidies to higher education in three countries
1986
Studies of the incidence of public susidies to higher education have commonly disregarded adjustements to an appropriate age range in the parental reference populations. Even where the need for such adjustements is noted, implications have rarely if ever been systematically analyzed. Moreover, no attention whatsoever seems to have been paid to implications for adult life-cycle experiences let alone secular changes in experiences over successive cohorts. The present paper seeks to fill part of these gaps, drawing on relevant parts of our research on "the political economy of government support of higher education : studies in Chile, France and Malaysia".
Life Cycle Costing: a tool to manage the urban water cycle
2013
The Water Framework Directive puts much emphasis on the role of economics for improving the management of water resources. In the context of the urban water cycle, previous studies have proven that Life Cycle Costing (LCC) is a useful methodology for assessing the costs of the whole cycle. However, there are many elements and factors that can influence the results of the LCC assessment and therefore affect the decision making process. The main aim of this study is to identify the main difficulties for carrying out LCC studies in the urban water cycle and to propose some solutions to overcome them. Hence, the conclusions obtained from the assessment of several case studies will be more robus…
Towards more sustainable airfield pavements using life-cycle assessment of design alternatives
2020
Airports are critical infrastructures and their success is paramount to development through tourism, trade and connectivity. Within the airport, the runway pavement must always be in a pristine condition. Consequently, pavement design and maintenance decisions are vital. Authorities must make decisions concerning preferred materials for design and maintenance. Decisions should be balanced by both economic and environmental factors. This paper considers a case study at Falcone Borsellino Airport (PMO), Palermo, Italy, where air traffic has been steadily increasing. Different pavements are proposed: flexible Asphaltic concrete designs with both traditional Asphaltic concrete and using reclaim…
The cost of green roofs disposal in a life cycle perspective: covering the gap.
2012
Abstract This study is aimed at providing a contribution in overcoming the current gap, especially in Life Cycle Costing (LCC) and Benefit – Cost (BCA) analyses, due to the lack concerning the green roof disposal costs. Therefore, we have applied to an actual extensive green roof the LCC methodology suggested by D. G. Woodward (that appears like one of the most formalized and generalizable), but we have extended the analysis to the disposal phase. This will allow a complete and proper application of the LCC methodology in order of achieving an economic accounting of this component through its life cycle. In this way, it is possible to achieve the complete evaluation of the “green roof” perf…
Economic and environmental sustainability of submerged anaerobic MBR-based (AnMBR-based) technology as compared to aerobic-based technologies for mod…
2015
[EN] The objective of this study was to assess the economic and environmental sustainability of submerged anaerobic membrane bioreactors (AnMBRs) in comparison with aerobic-based technologies for moderate-/high-loaded urban wastewater (UWW) treatment. To this aim, a combined approach of steady-state performance modelling, life cycle analysis (LCA) and life cycle costing (LCC) was used, in which AnMBR (coupled with an aerobic-based post-treatment) was compared to aerobic membrane bioreactor (AeMBR) and conventional activated sludge (CAS). AnMBR with CAS-based post-treatment for nutrient removal was identified as a sustainable option for moderate-/high-loaded UWW treatment: low energy consump…
Life cycle energy sustainability assessment: an expanded framework for energy technologies
2018
Life Cycle sustainability assessment is one of the most relevant tools delving in sustainability science, based currently on the triple bottom line idea, that is identified in the use of the three tools of Life Cycle Assessment (LCA), Life Cycle Costing (LCC) and Social Life Cycle Assessment (S-LCA). The methodology is structured on international regulations and is currently being applied to a wide set of products and systems. However, when targeting specifically energy technologies with this methodology some specific issues need to be taken in consideration before applying tout court the standard LCSA methodology. Energy systems – in particular those where fluid streams are used – have an …
