Conceptualizing a Framework: A Critical Review of the Development of Change Management Theories
2020
Abstract Although approaches to manage change dated back to as early as human history, managing effective change is still the topic of today’s debates. One of the undeniable facts about this is that change per se keeps changing, and so does its management methodology. While this fact comes, on the one hand, to validate the reason why none of the early theories stands relevant across time, it, on the other hand, proofs that change methodology is certainly fluid, giving no room for an approach to really last. An effective change is achievable [not] by a prescription, but by a thorough consolidation of the various aspects relevant to change. This paper aims therefore at identifying those [mana…
Developing a Pedagogical Framework and Design Principles for STEM Learning Environment Design
2020
The need for effective and attractive learning environments (LEs) for science, technology, engineering, and mathematics (STEM) has been internationally recognized. Additionally, the connection between STEM learning and cross-curricular skills such as creativity, innovation, and entrepreneurship has garnered attention. A deep theoretical and empirical understanding is required when designing STEM LEs. In this study, a pedagogical framework for STEM LEs has been developed based on feedback from students, aged 10–18 years old, teachers, school directors, parents, and STEM professionals, and supported by the literature. First, representatives of key stakeholder groups in Belarus, Finland, Germa…
Economic valuation of environmental benefits of removing pharmaceutical and personal care products from WWTP effluents by ozonation.
2013
Continuous release of pharmaceutical and personal care products (PPCPs) present in effluents from wastewater treatment plants (WWTPs) is nowadays leading to the adoption of specific measures within the framework of the Directive 2000/60/EC (Water Framework Directive). The ozonation process, normally employed for drinking water production, has also proven its potential to eliminate PPCPs from secondary effluents in spite of their low concentrations. However, there is a significant drawback related with the costs associated with its implementation. This lack of studies is especially pronounced regarding the economic valuation of the environmental benefits associated to avoid the discharge of …
Introduction of the circular economy within developing regions: A comparative analysis of advantages and opportunities for waste valorization
2018
The introduction of effective solid waste management strategies in developing countries should be considered for improving sustainability at global level. Many barriers should be overcome, concerning the introduction of environmental policies, effective investments, social inclusion and public awareness, which are significant issues in low-middle income countries. The Circular Economy could represent the answer for improving current solid waste management activities worldwide, since denote the principle of waste valorization and recycling for boosting developing economies. This paper is focused on this theme, analyzing main opportunities for improving the current state of solid waste manage…
Performance in the treatment of municipal waste: Are European Union member states so different?
2019
Abstract Efficient management and treatment of municipal waste is essential for achieving green growth. Recent studies have revealed convergence in European Union (EU) member states' performance in municipal waste treatment, particularly since the transposition of the 2008 European Waste Framework Directive into national laws. However, there are still notable differences between countries. In this paper, we calculate a composite indicator of performance in municipal waste treatment at the country-level. We also present an in-depth examination of differences in performance across EU member states. Our results show that the best performers—mainly high income Northern and Central European coun…
Modelling of E. colidistribution in coastal areas subjected to combined sewer overflows
2013
Rivers, lakes and the sea were the natural receivers of raw urban waste and storm waters for a long time but the low sustainability of such practice, the increase of population and a renewed environmental sensibility increased researcher interest in the analysis and mitigation of the impact of urban waters on receiving water bodies (RWB). In Europe, the integrated modelling of drainage systems and RWB has been promoted as a promising approach for implementing the Water Framework Directive. A particular interest is given to the fate of pathogens and especially of Escherichia coli, in all the cases in which an interaction between population and the RWB is foreseen. The present paper aims to p…
Iron-based metal-organic framework: Synthesis, structure and current technologies for water reclamation with deep insight into framework integrity.
2021
Water is a supreme requirement for the existence of life, the contamination from the point and non-point sources are creating a great threat to the water ecosystem. Advance tools and techniques are required to restore the water quality and metal-organic framework (MOFs) with a tunable porous structure, striking physical and chemical properties are an excellent candidate for it. Fe-based MOFs, which developed rapidly in recent years, are foreseen as most promising to overcome the disadvantages of traditional water depolluting practices. Fe-MOFs with low toxicity and preferable stability possess excellent performance potential for almost all water remedying techniques in contrast to other MOF…
Unravelling environment and politics in the Spanish press. From Franco’s dictatorship to democracy
2017
The 1970s and 1980s were key years for the consolidation of environmentalism and environmental communication. In Spain, the special political situation during General Franco’s military dictatorship conditioned the coverage of environmental issues, as did the transition to democracy. The Albufera Natural Park (Valencia, Spain) was a particularly significant case in this context, since it was involved in one of the first environmental protests to protect a natural area covered by Spanish media. In this paper, we study opinion articles published in the Valencian newspapers Las Provincias and Levante, in order to analyze the evolution of the environmental discourse in Spanish society from the d…
Epigenomics and metabolomics reveal the mechanism of the APOA2-saturated fat intake interaction affecting obesity
2018
BACKGROUND: The putative functional variant −265T>C (rs5082) within the APOA2 promoter has shown consistent interactions with saturated fatty acid (SFA) intake to influence the risk of obesity. OBJECTIVE: The aim of this study was to implement an integrative approach to characterize the molecular basis of this interaction. DESIGN: We conducted an epigenome-wide scan on 80 participants carrying either the rs5082 CC or TT genotypes and consuming either a low-SFA (C genotype, promoting an APOA2 expression difference between APOA2 genotypes on a high-SFA diet, and modulating BCAA and tryptophan metabolic pathways. These findings identify potential mechanisms by which this highly reproducible ge…
Characterisation of electric alloys for electric drives
1996
Knowledge of the magnetic and loss charactenstics of electric alloys is necessary for the computation and design of electrical machines. Over a long period of time, and more recently, many devices have been proposed for this characterisation. They test ferromagnetic sheets under conditions of unidirectional magnetic flux density. Other methods are derived from some of these devices, but they use conditions of rotating flux density. In the paper the authors show with the use of numerical computation that, in all these testing systems, the distribution of the magnetic flux density through the thickness of the sheet is uniform and does not take into account the edge effect which exists in rota…
