Verso le nuove competenze. Il pensiero progettante nei percorsi di apprendimento per l’istruzione secondaria superiore.
No full textIl design, nella sua forma di “pensiero progettante e produttivo”, può essere considerato come una leva per attivare forme di innovazione di specifici spazi di apprendimento nel campo educativo, in particolare nell’istruzione secondaria superiore. La lettura proposta si sviluppa attraverso due prospettive: individuare relazioni tra pensiero progettante e pedagogia costruttivista; far emergere quali siano gli ambiti educativi nei quali, ad oggi, sia più urgente adottare ap- procci guidati dal design per attivare pensiero critico, auto-consapevolezza e coscienza sociale. Infine, vengono introdotte tre sperimentazioni in cui il design, inteso come modo di pensare e agire, funge da innesco per scoprire, attivare e alimentare nuove forme di apprendimento.Design, in its form of “productive thinking”, can be considered as a lever to activate forms of innovation of specific learning spaces in the educational field, particularly in upper secondary education. The proposed reading is developed through two perspectives: identifying relations between design thinking and constructivist pedagogy; highlighting the educational areas in which it is most urgent to adopt design-led approaches to activate critical thinking, self-awareness and social awareness. Finally, three experiments are introduced in which design, understood as a way of thinking and acting, plays the role of a trigger to discover, activate and cultivate new forms of learning
Knowledge co-creation for flexible packaging: learning from a case study
Full text linkThe capacity of enterprises to create knowledge throughout the innovation process has been pinpointed as a pivotal source of competitive advantage (Bierly et al., 2009; Grant, 1996). In recent decades, corporations have come to recognize that such knowledge creation cannot be confined exclusively within the organizational realm. In order to increase their pool of knowledge, businesses are progressively involving external stakeholders during the innovation process in the co-creation of knowledge (Hoyer et al., 2010; Mahr et al., 2014). Different studies investigated and illustrated the process by which enterprises integrate a specific category of external stakeholders into their innovation processes (Horn and Brem, 2013). In particular, a current of research is dedicated to investigating the involvement of empowered consumers in such processes (Kazadi et al., 2016). As far as innovation process is concerned, environmental or green innovation has been the main innovation focus of interest for many researchers (e.g. Amores-Salvado et al., 2014). Beyond the environmental aspects, several benefits derive from environmental innovation. For example, it allows to lower external costs (e.g., Beise and Rennings, 2005), allows the improvement of companies’ efficiency, cost reduction, satisfies demand of environmentally friendly consumers, improves financial and business profitability (Amores-Salvado et al., 2014). However, Cainelli et al. (2015) have shown that environmental innovations are characterized by high levels of uncertainty, novelty and variety. Consequently, in such a context knowledge co-creation should have a fundamental role in facing the above mentioned challenges. Based on these premises, the purpose of our study is to improve our understanding of how knowledge is co-created with consumer involvement in the environmental innovation process, and which technological capabilities a lead firm requires to manage this knowledge co-creation process. In addressing these issues, we conducted a comprehensive literature review on the topic of knowledge co-creation, followed by a case study involving an innovative startup operating in the development of flexible packaging
Mechanical Characterization of Sustainable Mortars with Recycled Aggregates from Construction and Demolition Wastes: An Experimental Investigation
No full textThe use of recycled aggregates in the production of concrete and mortar represents a sustainable way to reintroduce these constituents-which are typically treated as waste and disposed of-in the production chain, providing new value to potentially polluting materials. The effect of recycled aggregates has been widely studied in the production of concrete due to the directions of National Standards in Italy; however, their role in the manufacturing of mortar must be investigated further due to the high variability that can be observed in the literature. In particular, the aim of this paper is the mechanical characterization of sustainable mortars defined by different mix designs and different binders, in which the aggregates are gradually replaced by a recycled sand obtained from the grinding of construction and demolition wastes, which could include old concrete, clay bricks, and minimal amounts of other kinds of residual materials. This investigation is carried out through experimentation, taking into account four different mortar compositions defined by an increasing percentage of recycled constituents. Virgin aggregates are also studied for the sake of comparison. The results, accomplished through a three-point bending test and an unconfined compression test, show that it is still possible to maintain acceptable mechanical properties by using these wastes as aggregates in spite of a decrease in the analyzed values. In general, the mean reductions with respect to the use of natural aggregates are about 30-40% and 35-55%, respectively, for compressive and flexural strengths. It should be highlighted that some experimental sets provide a maximum reduction of 70-80%, but the results are still within the limitations of the standards. This aspect can be considered to be a good compromise since the production of this sustainable construction material can represent a solution that is able to reduce the extreme exploitation of natural resources, the pressure on landfills, and the consumption of energy, which are related to the construction industry
Vibrations and bending of thin laminated square plates with holes in gradient elasticity: A finite element solution
No full textNonlocal elasticity is becoming more and more popular due to the introduction of advanced constituents and the need of a peculiar approach able to capture size-dependent effects. Strain gradient theory falls within this aim, and it is included into the thin plate formulation in the current paper. Following the procedure developed in Bacciocchi et al. (2020, 2021), a finite element model based on higher-order Hermite interpolating functions is used here to evaluate the mechanical behavior of laminated composite square plates with holes. These peculiar configurations cannot be solved analytically
