The Role of Corporate Social Responsibility (CSR) in the New Economy
2004
The idea of corporate social responsibility has come to be accepted as one of the major components of business growth and sustainability. The success in the new economy comes with various challenges. Those challenges require business and their managers to think beyond traditional way of looking for short-term goals. It requires business and the people inside these behemoths to embrace a much broader perspective that is also inclusive of stakeholders. The nature of society we are living in has changed. The nature of governance has equally changed since people are now enjoying more freedom within each societal democratic tenet. This freedom has found its way in the business and into the facto…
Living the urban challenge : sustainable development and social sustainability in two southern megacities
2007
Kehitysmaiden nopea kaupungistuminen ja miljoonakaupunkien voimakas kasvu luovat haasteita kestävään kehitykseen tähtäävälle suunnittelulle. Kansainvälisissä kehitysohjelmissa on pyritty turvaamaan suurkaupunkien taloudelliset ja ympäristölliset tavoitteet. Kestävän kehityksen sosiaalinen ulottuvuus on usein rajattu kaupunkien tarjoamiin sosiaalipalveluihin.- Ympäristön säilyttäminen tuleville sukupolville ei onnistu vain talouteen, ympäristöön ja palveluihin kohdistuvilla teknisillä toimilla. Tämä johtuu etelän suurkaupungeille tyypillisestä räikeästä sosiaalisesta eriarvoisuudesta. Suurkaupunkien suunnittelussa tulisi analysoida sellaisia sosiaalisia haasteita, jotka heikentävät kaupunkie…
Creating ‘Communities of Practice’ to Enhance Ecosocial Work : A Comparison between Finland and Australia
2022
Abstract This article reports on findings from a small qualitative study in two industrialised countries—Finland and Australia, which aimed to engage social work practitioners in ‘communities of practice’ to collaboratively explore ecosocial work practice. Using a Participatory Action Research approach, a series of workshops were established to plan, implement and evaluate ecosocial work interventions. Data were gathered using qualitative pre- and post-surveys to examine changes to practice, including similarities and differences between Finnish and Australian practitioners. Overall, results indicated that practitioner engagement in the workshops increased their capacity to implement ecosoc…
EdenMed: innovazione sostenibile. Il modello Inquiry based Learning in educazione
2022
Il tema della sostenibilità è oggi al centro di un dibattito che si va progressivamente articolando e arricchendo, mettendone in luce la complessità e sottolineando al contempo la necessità di un approccio olistico ed ecosistemico (Bhattacharjee, Debnath; Hinzen, Schmitt, 2016; Leicht, Heiss, Byun, 2018; Lundvall, Fröberg, 2022; Malavasi, 2020; Stein et alii, 2022;). L’Agenda 2030, firmata da tutti i Paesi dell’ONU nel 2015, impegna governi, comunità educanti e singoli verso un nuovo modello di sviluppo sostenibile, capace di ristabilire un equilibrio tra i diversi sistemi prima che si arrivi ad un punto di non ritorno. La sostenibilità non è una questione puramente ambientale. Con l’agenda…
Monialustaisten mobiilisovellusten kehittämistavat
2017
Mobiililaitteiden käyttö on lisääntynyt huomattavasti lähivuosina, joten sovelluksia kehitetään yhä enemmän. Sovellusten kehittäminen kuhunkin ympäristöön natiivisti on kuitenkin kallista ja vaatii runsaasti aikaa, sillä sovellukset joudutaan luomaan alustoille erikseen. Monialustainen mobiilisovelluskehitys pyrkii tuomaan ratkaisun tähän ongelmaan mahdollistamalla sovelluksen toiminnan usealla alustalla yhden ohjelmakoodin pohjalta. Tässä tutkielmassa käydään läpi mitkä hyödyt ja haasteet ovat tyypillisiä natiiveille webpohjaisille, hybrideille, tulkatuille ja käännetyille sovelluksille. Lisäksi tutkielmassa vertaillaan neljän erilaisen ohjelmistokehyksen ominaisuuksia, sekä mitä rajoittei…
The Industrial Applicability of PEA Space Charge Measurements, for Performance Optimization of HVDC Power Cables
2019
Cable manufacturing industries are constantly trying to improve the electrical performance of power cables. During the years, it was found that one of the most relevant degradation factors influencing the cable lifetime is the presence of space charge in the insulation layer. To detect the accumulated charge, the pulsed electro-acoustic (PEA) method is the most used technique. Despite the wide use of the PEA cell, several issues are still present. In particular, the PEA output signal is strongly disturbed by the acoustic waves reflections within the PEA cell. This causes the distortion of the output signal and therefore the misinterpretation of the charge profiles. This, in turn, may result…
Spatial Succession for Degradation of Solid Multicomponent Food Waste and Purification of Toxic Leachate with the Obtaining of Biohydrogen and Biomet…
2022
A huge amount of organic waste is generated annually around the globe. The main sources of solid and liquid organic waste are municipalities and canning and food industries. Most of it is disposed of in an environmentally unfriendly way since none of the modern recycling technologies can cope with such immense volumes of waste. Microbiological and biotechnological approaches are extremely promising for solving this environmental problem. Moreover, organic waste can serve as the substrate to obtain alternative energy, such as biohydrogen (H2) and biomethane (CH4). This work aimed to design and test new technology for the degradation of food waste, coupled with biohydrogen and biomethane prod…
Comparison of local electrochemical impedance measurements derived frombi-electrode and microcapillary techniques
2009
Abstract In the present paper, local electrochemical impedance spectra were obtained on a 316L stainless steel from two configurations: a dual microelectrode (bi-electrode) and microcapillaries. With the bi-electrode, the local impedance measurements were made from the ratio of the applied voltage to the local current density calculated from the application of the ohm's law. With the use of microelectrochemical cells, the specimen surface area in contact with the electrolyte is limited by the use of glass microcapillaries and the local impedance was defined from the ratio of the local potential to the local current restricted to the analysed surface area. Differences and similarities observ…
Dynamika uwalniania azotu z nawozów o powolnym działaniu w eksperymencie laboratoryjnym
2016
Sustainable fertilization is one of the most important treatments of modern agriculture. Organic agriculture with new demands on agricultural practice, seeks to restrict the use of mineral fertilizers in favor of slow-action organic fertilizers. The fertilizers which are made on the farm are particularly valuable due to their quality and the absence of costs of purchase and transport. From this point of view, the new possibilities of using an organic matter which comes from waste of the food industry or biodegradable wastes from households proves to be interesting. Due to the absence of contamination with other types of waste, it can be used for the production of a fertilizer which could be…
