Applicability of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) bark extract as a precursor of rigid carbon foam and activated carbon

2023

Hybrid aspens have long attracted scientific interest, but the research on their use as feedstocks for chemical applications are still very limited. The bark biomass of the poplar species contains many valuable extractives that can be utilized as value-added products. This paper examines the applicability of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) bark extract as a precursor of rigid carbon foam and activated carbon. To explore this, the study considers 1) the basic chemical composition of the bark in terms of added value potential, 2) the basic chemical composition of the bark extract and the effect of its pretreatment on the extract composition, 3) the production of rigi…

INNOVATION AND NEW TECHNOLOGIES TO ENHANCE THE ARCHITECTURAL HERITAGE IN THE HISTORIC CITY.THEORY AND TOOLS

2016

The ancient heritage is a fundamental territorial resource, the reason why territory protection and conservation have to be reinforced, as much as it’s necessary to improve its promotion and responsible use. In particular, cultural heritage promotion inside the cultural circuit, gives the chance to own the territory in terms of social and tourist resource. In this perspective, the process of valorization of the historical sites must be proactive and strategic in order to spread knowledge of cultural heritage, through the use of advanced tools for the understanding of the exhibition in the museum context; but also to improve the public use. As part of integrated strategies for sustainable de…

Harnessing Digital Services for Co-creating Sustainability Value in the Retail Servicescape

2022

While the importance of sustainable consumption is well acknowledged and consumers increasingly demand sustainable alternatives, the consumption of environmentally strenuous products continues to grow. Technological solutions have been discussed for addressing the misalignment between consumers’ attitudes and behavior. This study is the first to use the service-dominant logic lens to investigate how digital services may be harnessed to drive the co-creation of sustainability value in the retail industry. We conduct 10 semi-structured interviews with a Finnish retail company and its customers and reflect on the customers’ experiences with respect to the company’s value propositions in the se…

Project-Based Education Research Course Supports Exchange-students’ Research Minded Teacher Identity

2022

Project-based education (PBE) gives possibilities for students to work together and feeling of belonging in a community even during distance learning. At the Department of Chemistry, University of Jyväskylä (JYU), a group of exchange students participated in a PBE chemistry teacher education research course online. The goal of the course was to enforce the connection between research on science teaching and acting sustainable in society. This study is based on semi-structured online group interview of the students after this PBE course. The main focus of this investigation was how positive feelings and attitude affect learning. peerReviewed

Examining the antecedents and consequences of perceived value : a case study of mobile banking application usage in the Kingdom of Saudi Arabia

2022

Recent advancements in information, communications, and mobile technologies have revolutionized banking and payment services as well as consumer behavior. This study examines the continuous usage experience of mobile financial services, and especially mobile banking services, in the Kingdom of Saudi Arabia (KSA), the context of this study. Data were collected from 300 experienced mobile banking users across the KSA using a pre-tested survey instrument. The partial least squares structural equation modelling (PLS-SEM) was used to analyze the data. The results supported most of the hypotheses and revealed that e-service quality, e-information quality, and experience flow have a significant an…

An intergenerational competency framework : Competencies for knowledge sustainability and start‐up development in the digital age

The results of this study shed light on understanding the necessary competencies of entrepreneurs for intergenerationally supported start-up innovation by providing 27 competencies categorized as follows: intergenerational safety facilitation, cultural awareness, virtues for growth, effectual …

Dry stone buildings in Sicily. An environmental and territorial resource

2013

Dry stone constructions are widespread throughout many regions across the world, in a wide variety of forms, according to the environmental and socio-economic contexts, and constitute a valuable know-how which is today in danger of disappearing. In Sicily dry stone works have traditionally been used in the area of Val di Noto where they constitute a key character of the landscape, and in the Madonie Mounts in which some policies of enhancement have been recently initiated. In the framework of the Grundtvig programme “La préservation du patrimoine architectural bâti en pierre sèche”, an in-depth analysis of these architectures have been pursued, aiming to create a database inventory. This pa…
