Sysmä Community Currency: An Analysis of its Success from the Perspectives of Purposes, Stakeholders and Promotion
2019
Artikkeli on tapaustutkimus paikallisrahajärjestelmästä, jota kokeiltiin äskettäin maalaisympäristössä Sysmän kunnassa. Paikallisraha on yksi innovaatiivisista aloitteista, joita kunta on tehnyt tällä vuosituhannella torjuakseen jo 1960-luvulta alkaen käynnissä ollutta väestökatoa. Tässä artikkelissa tutkitaan paikallisrahan käynnistysvaihetta siihen sisältyneiden ristiriitojen näkökulmasta. Artikkelissa todetaan, että järjestelmä kärsi epäselvästä tavoitteenasettelusta, ja että eri osallisilla oli tavoittesta vaihtelevia ja ristiriitaisia käsityksiä. Paikallisrahan sosiaalista hyväksyntää heikensivät päätös rajoittaa rahaa vastaanottavien yritysten joukko kunnassa kirjoilla oleviin yrityks…
Towards a new protocol for field measurements of greenhouse gases from wastewater treatment plant
2016
Emissions into the atmosphere of greenhouse gases (GHGs), i.e., carbon dioxide, methane and nitrous oxide from wastewater treatment plants are of increasing concern in the water industry. In order to produce useful and comparable information for monitoring, assessing and reporting GHG emissions from wastewater treatment plants, there is a crescent need for a general accepted methodology. This paper aims at proposing the first protocol for monitoring and accounting GHG emissions from wastewater treatment plants taking into account both direct and internal indirect emissions focusing on sections known to be major responsible of GHG emissions i.e. oxidation tanks and sludge digestion. The main…
Analytical results for 2-D non-rectilinear waveguides based on a Green's function
2008
We consider the problem of wave propagation for a 2-D rectilinear optical waveguide which presents some perturbation. We construct a mathematical framework to study such a problem and prove the existence of a solution for the case of small imperfections. Our results are based on the knowledge of a Green's function for the rectilinear case.
Plant essential oils in controlling fungal colonization on wooden substrate
2021
In order to control fungal colonization and the related deterioration process of cultural objects, several chemical compounds are actually utilised. These products generally are toxic, not biodegradable and persisting for long time in the environment, also acting on not-targeted biological systems. In this study, specifically to wooden cultural object, Origanum vulgare L. and Thymus vulgaris L. essential oils are proposed as green biocides to contrast the development of Penicillium chrysogenum, Aspergillus flavus and Aspergillus niger fungal species. The aim is replacing toxic products with natural molecules, proposing alternative methodologies supporting the using of non-toxic novel compou…
Microbial dynamics during green Sicilian table olive fermentations
2009
The production of green table olives is traditionally a spontaneous fermentation carried out by indigenous microflora. Variability of microbial raw material may result in changes in the qualitative aspects of final products (Silvestri et al., 2009). Table olives of five different green table olive cultivars (four Sicilian Brandofino, Castriciana, Nocellara del Belice and Passalunara and the Spanish Manzanilla) were produced according to a semi-industrial technology, in which lactic acid bacteria (LAB) role is partially replaced by lactic acid addiction. Transformation processes were studied by a combined strategy consisting of chemical, microbiological and sensory analyses. Yeasts harboured…

Customer Environmental Values and Their Contribution to Loyalty in Industrial Markets
2016
Concern over the effect of industries on the natural environment is growing on a multitude of levels. This study examines the effects of how perceptions of (a) environmental values, (b) green image and (c) perceived value of industrial customers influence their loyalty towards suppliers in existing relationships, and how the length of B2B relationships may moderate these linkages. A conceptual framework is developed and data are collected from a global sample (N =121) of B2B customers. We find that both green image and perceived value have a direct positive link with customer loyalty and that environmental values are positively linked to the green image of the supplier. Moreover, the effect…
Zarządzanie funkcją środowiskową w rolnictwie - źródło nowych rent gospodarstw rolnych
2016
W Unii Europejskiej ekologizacja rolnictwa stanowi wstępny etap takiej jego transformacji, która umożliwi gospodarstwom rolnym, rozmieszczonym w różnych miejscach przestrzeni europejskiej, trwały udział w kreowaniu zielonego wzrostu. Praca jest próbą odpowiedzi na pytanie: Czy dzięki doskonaleniu zarządzania funkcją środowiskową towarowe gospodarstwa rolne regionu opolskiego mogą przygotować się do wyzwań związanych z gospodarką sieciową i zadań obecnego etapu ich modernizacji? W opracowaniu przedstawiono rolę polityki ekologicznej w definiowaniu obecnego etapu modernizacji gospodarstw rolnych, mechanizmy jej integracji z celami WPR do 2020 r. oraz strategią Europa 2020. Ustalenia te stanow…
"On-the-go" multispectral imaging system embedded on a track laying tractor to characterize the vine foliage
2015
Mutispectral imaging systems are widely used in remote sensing for Precision Viticulture. In this work, this technique was applied in the proximal sensing context to characterize vine foliage. A mobile terrestrial experimental system is presented, composed of a GPS receiver, a multi-spectral camera acquiring visible and near infrared images, and a Greenseeker RT-100 which measures the Normalized Difference Vegetative Index (NDVI). This optical system observes vine foliage in the trellis plan, in natural sunlight. The experimental field is planted with Chardonnay, Pinot Noir and Meunier cultivars in a latin squared pattern. In 2013, six datasets were acquired at various phenological stages.S…
"Greenpeace" sociālo reklāmu par okeāna piesārņojumu semiotiskā un vizuālo metaforu analīze
2020
Bakalaura darba ““Greenpeace” sociālo reklāmu par okeāna piesārņojumu semiotiskā un vizuālo metaforu analīze” mērķis ir izpētīt “Greenpeace” reklāmas par okeāna piesārņojumu, lai atklātu un analizētu zīmes un metaforas, kas tiek izmantotas to vēstījumos un kāda ir to ietekme un iedarbība uz auditoriju. Darbs sastāv no teorētiskās, metodoloģijas, empīriskās un secinājumu daļām. Bakalaura darba teorētisko bāzi veido reklāmas, semiotikas, zīmju un metaforu teorijas. Empīriskā daļa sastāv no kvantitatīvas, kvalitatīvas kontentanalīzes, semiotiskās analīzes un fokusa grupas metodes. Kopumā tika izanalizētas 83 reklāmas, no tām 70 bija drukas un 13 – video reklāmas. Semiotiskai analīzei atsevišķi…
