A Top-Down Approach Based on the Circularity Potential to Increase the Use of Reclaimed Asphalt
2023
Resource depletion and climate change, amongst others, are increasingly worrying environmental challenges for which the road engineering sector is a major contributor. Globally, viable solutions that comply with the principles of circular economy (CE) are being investigated that can replace conventional asphalt mixtures in a post-fossil fuel society. The use of reclaimed asphalt (RA) is a widely used and well-established method to reduce the environmental and economic impacts of asphalt mixtures while increasing their circularity. However, RA’s market supply and demand have not yet been systematically analyzed and established. Moreover, the actual circularity potential and the opportu…
Mapping a-priori defined plant associations using remotely sensed vegetation characteristics
2014
Abstract Incorporation of a priori defined plant associations into remote sensing products is a major challenge that has only recently been confronted by the remote sensing community. We present an approach to map the spatial distribution of such associations by using plant indicator values (IVs) for salinity, moisture and nutrients as an intermediate between spectral reflectance and association occurrences. For a 12 km 2 study site in the Netherlands, the relations between observed IVs at local vegetation plots and visible and near-infrared (VNIR) and short-wave infrared (SWIR) airborne reflectance data were modelled using Gaussian Process Regression (GPR) (R 2 0.73, 0.64 and 0.76 for sali…
A multi-input, single-inductor power system for multisource energy harvesting
2013
Today, energy harvesting is drawing a great deal of attention due to modern trends in energy saving and sustainable development purposes. Among renewable energy sources fuel cells and photovoltaic arrays are the most promising for a wide variety of applications, ranging from few mWatts of wireless sensor networks to kWatts for household appliances. Coupling several harvesters and renewable sources is the winning strategy to ensure a proper supply overcoming the uncertainty and limited availability of common harvesters and renewable sources. Multisource energy harvesting is actually an open research topic involving several pressing and often conflicting requirements. System cost, complexity,…
Rośliny naczyniowe jako bioindykatory stanu środowiska
2017
Dzięki coraz nowocześniejszym i powszechniej stosowanym metodom bioindykacji można dokonać precyzyjnej i stosunkowo wydajnej oceny stanu środowiska naturalnego oraz zmian w nim zachodzących.Wymiernym sposobem monitoringu przyrody są obserwacje reakcji żywych organizmów. Badania przeprowadza się głównie z użyciem stenobiontów, czyli taksonów o małej tolerancji na zmienność warunków środowiska. Grupę roślin oraz zwierząt wykorzystywanych w badaniach bioindykacyjnych nazywa się wskaźnikowymi.Bioindykacja znajduje zastosowanie w geologii poszukiwawczej do odnajdywania miejsc z możliwością pozyskania cennych kruszców oraz w ochronie środowiska do monitoringu stanu jego zanieczyszczenia. Na podst…
The sustainability report in the the NPOs. An innovative model
2014
The growing attention toward sustainability report pushed companies, private and public as well, to adopt instruments able to rate sustainability and environmental impact. Many tools can be used to evaluate social communication but the sustainability report is the most complete to explore, measure, understand and communicate the results under this aspect. Through the sustainability report is possible to supply a balanced vision of the sustainability performance of an organization and to understand all the positive and negative effects generated running the activity. To report the activity NPOs as well, has to disclose results and their connection with the surrounding community as social, en…
Strategic Environmental Analysis (SEA) of the building Sector: an Annotated List of Indicators and a Simple Methodology
2003
With respect to the SEA of the town planning scheme of the Sicilian region, we will analyse through the paper the most commonly adopted indicators of sustainability and we will select the most promising of them for the purpose. Moreover, a simplified approach will be introduced for the assessment of the SEA by utilising both simple and aggregate indicators: simple indicators (selected among those proposed in the literature) will lead to the “technical” assessment of the SEA, while aggregate indicators (built up by properly grouping the simple ones) will lead to the “political” assessment of the Sicilian urbanistic sector. Simple indicators will refer to official data, essentially concerning…
Increasing the Circularity of asphalt mixtures: Integrated Sustainability and Circularity Assessment as a progress monitoring tool towards more Circu…
2021
Sustainability and Circular Economy (CE) are two concepts that lately have been profoundly linked to each other. The road engineering industry has gradually been adapting practices that are considered both circular and sustainable. However, not all of these practices entirely consider the whole life environmental and circularity assessment and implications of asphalt mixtures.; which in turn leads to doubtfully circular and sustainable approaches. For this reason in this thesis, after analysing the ways that National Road Authorities implement and communicate CE through questionnaires and web searches, a Material Circularity Index quantifying framework, based on the proposed methodology of …
Promuovere e valutare le abilità di pensiero critico nella formazione iniziale degli insegnanti
2019
L'articolo presenta una ricerca che analizza e valuta un percorso di formazione dei futuri insegnanti di scuola primaria e dell’infanzia, per lo sviluppo delle abilità costitutive del pensiero critico durante il terzo anno del tirocinio universitario. Si è inteso conoscere gli esiti conseguiti da 200 soggetti, prossimi all’insegnamento nella scuola, quando pianificano e realizzano un intervento in classe, e quali possibili difficoltà incontrano nelle fasi di sviluppo dell’azione didattica programmata. La progettazione didattica è stata utilizzata dagli studenti sia come struttura sia come guida dell’azione, perché ha preparato la sequenza delle attività di insegnamento, ha anticipato l’orga…
Finanšu cikla novērtējums Latvijā
2018
Diplomdarbā tiek novērtēts Latvijas finanšu cikls ar struktūras laikrindu modeļiem (STSM), faktoru analīzi un finanšu cikla indeksu. Cikla robustuma pārbaudei tiek lietota Beijesa modeļu svēršana (BMA) un impulsu reakcijas funkcijas. Iegūtie rezultāti liecina, ka Latvijā finanšu cikls savu virsotni bija sasniedzis 2008. gadā, pastiprinot ekonomiskās krīzes izraisītās sekas. Pēc finanšu cikla samazināšanās fāzes, ciklam ir sākusies jauna ekspansīvā fāze kopš 2015. gada.
Measuring technical efficiency of Greek red suckler cow breed's farms in Central Macedonia region using a data envelopment analysis model
2022
This study aims to estimate the technical efficiency (TE) of a randomly selected sample of red Greek suckler cow breed farms in the area of Central Macedonia and identify the most technically efficient characteristics of cow-calf operations. Moreover, this work wants to verify the impact of local and European policies in support of the sector on the estimated efficiency. The research investigates the technical efficiency of 64 suckler cow farms by using the data envelopment analysis (DEA) method. Findings reveal that the most efficient farms were larger, with higher gross revenue, and higher cost of fixed capital than non-efficient farms. In addition, the cost of variable capital, which dir…
