    The purpose of this thesis is to show the applicability of the Lean Thinking to the other activities of the value creation flow not only the production process, in this case the supply chain. The first step of the research is the analysis of continuous improvement as one of Total Quality Management principles and how it is implemented by organizations through Lean Production meth-odology. The second step is the initial study of the characteristics of supply chain and Supply Chain Man-agement in order to understand what aspects can be combined and improved with lean methods, and the final study of Lean Supply Chain. The last phase is the presentation of a case study, a successful implementation of continuous im-provement in the supply function with the establishment of long-term relations with suppliers with the aim to eliminate waste connected with controls on materials supplied

    In recent years several studies have been carried out attesting to the importance of motor education within Primary schools. The integration of physical activity into the school curriculum is a way to increase levels of movement by interrupting static moments produced by the traditional lesson, and in unison, stimulate with active methodologies the acquisition of more complex content and making them more motivating. Motor exercises are therefore not only beneficial or health-based but, when linked with cognitive objectives, they can also improve school learning. A systematic review has been carried out on the main search engines to understand the results obtained in the cognitive, motor and educational fields at European level and beyond, reflecting on any adjustments to be made or taking for example those experiments that have obtained positive needs, as a sample for a strengthening of motor activity in primary school, still not always carried out also at institutional level and not easy to investigate in this particular target audienc

    The "COSMOB QUALITAS PRAEMIUM": a quality brand in the Italian furniture sector

    No full text
    In recent years, attention by enterprises towards environmental issues is increased, taking on a strategic role in the activity of the same. The quality environmental standards are higher. The "Green Economy" theme has become a central topic of economic and social debate and many companies use it to improve their competitive performance. In Italy, for example, from 2008 to 2013, already 328,000 companies have invested in green technologies to reduce their environmental impact. Moreover, the consumer often wants to have certainty on the environmental commitment of the company or the environmental performance of the product he is about to buy. In many industries and for many products there is some confidential information to the customer. In the wood-furniture sector, this information is not explicitly defined. The aim of the paper is to analyze a tool to guarantee the consumer for the environmental quality of the product in the wood-furniture sector: the COSMOB QUALITAS PRAEMIUM (CQP), one of the few voluntary eco-labels in Italy, along with the "CQA" brand, the market leader

    Application of the lean manufacturing approach in an Italian firm: the case of the IMAB GROUP S.P.A.

    The purpose of the paper is to present a study on the successful application of the lean manufacturing model by a firm in Italy. Lean manufacturing or lean production is a production practice that considers the expenditure of resources for any goal other than the creation of the value for the end customer to be wasteful, and thus a target for elimination. Lean manufacturing involves the production of goods using less of everything: less waste, less human effort, less manufacturing space, less investment in tools and less engineering to develop a new product. This model implies a strategic, proactive and global approach that could prove effective in a turbulent and changing environment, such as the one businesses are currently facing. The case of the IMAB GROUP s.p.a. presented herein is a good example of how a firm has managed to implement the lean manufacturing model. The case study furnishes an example of a well-designed lean method application. The IMAB GROUP's excellent results and growth have attracted the attention of industry rivals in Italy and internationally, and the authors highlight how the principles of TQM and lean manufacturing can help a firm to be successful and to maintain that success

    In questo studio è stato indagato, nella scuola primaria, l’effetto di un intervento di educazione motoria mirato allo sviluppo dei pre-requisiti delle capacità di letto-scrittura. Due classi prime sono state assegnate, rispettivamente, ad un gruppo di controllo, che effettuava lezioni di attività motoria (1 ora, 2 volte a settimana per tutto l’anno scolastico) con contenuti standard, e ad un gruppo sperimentale, che effettuava lo stesso monte ore di lezione con i medesimi contenuti, ma dedicava parte delle ore ad un intervento sperimentale di attività motoria appositamente ideato per il miglioramento dei pre-requisiti della letto-scrittura. Prima e dopo la sperimentazione i bambini di entrambe le classi sono stati sottoposti a valutazione delle capacità di letto-scrittura (SD1), delle abilità di locomozione e controllo oggetti (TGM), e della dominanza laterale. I risultati sono stati confrontati con test non parametrici per campioni indipendenti (raffronto inter-gruppo dei valori dei pre-test e delle variazioni nel corso dell’anno scolastico) e per campioni dipendenti (raffronti intra-gruppo della variazione tra i valori pre- e post-test). I risultati evidenziano un miglioramento significativamente maggiore di SD1 e dei TGM nel gruppo di controllo rispetto al gruppo sperimentale ed incrementi significativi della dominanza laterale in entrambi i gruppi. In conclusione, l’attività motoria migliora significativamente l’apprendimento dei prerequisiti per la letto-scrittura

    Bathing water quality on the coastal belt of the province of Pescara (Italy, central Adriatic sea)

    The quality of bathing water is fundamental, not only from an environmental point of view but also due to the economic importance of tourism. This paper examines the water profile in the coastal belt of the province of Pescara (Italy, Central Adriatic Sea) with reference to the microbiological parameters Escherichia coli and intestinal enterococci required by Directive 2006/07 of European Commission. The water quality of 15 coastal beaches was surveyed; data were produced from monitoring and controls made available by the Abruzzo Regional Environmental Prevention and Protection Agency (ARTA) and extracted and elaborated for the period of interest (2010–2013). The data highlight critical situations in various parts of the coast; these problems can be attributed to river pollution, mainly due to the malfunctioning of the treatment plants for urban wastewater

    Circus-mobility: The value of a circus laboratory at school

    No full text
    The circus has always fascinated children due to its magic, imaginary and creativity. In this work, we analyse international research which emphasises the value of the discipline of the circus in relation to mobility. The aim of the study is to introduce the circus into schools. Although there is no unique definition of circus pedagogy as yet, scholars agree that such a discipline could provide a valid alternative to learn and deepen various mobility contents. We report examples of proposed school activities from the international landscape. Taking into consideration that circus pedagogy is little known in Italy, a comparison with the “National curriculum guidelines for 2012” Italy, was key to adapting this discipline to the Italian school context (in nursery and primary school) contributing to create and integrate a pupil’s mobility experience creatively

Max-Plank-Institut für Astrophysik; Germany.We implement a sub-resolution prescription for the unresolved dynamical friction onto black holes (BHs) in the OpenGadget3 code. We carry out cosmological simulations of a volume of 16 cMpc3 and zoom-ins of a galaxy group and of a galaxy cluster. The advantages of our new technique are assessed in comparison to commonly adopted methods to hamper spurious BH displacements, i.e. repositioning onto a local minimum of the gravitational potential and ad-hoc boosting of the BH particle dynamical mass. The newly-introduced dynamical friction correction provides centering of BHs on host halos which is at least comparable with the other techniques. It predicts half as many merger events with respect to the repositioning prescription, with the advantage of being less prone to leave sub-structures without any central BH. Simulations featuring our dynamical friction prescription produce a smaller (by up to 50% with respect to repositioning) population of wandering BHs and final BH masses in good agreement with observations. As for individual BH-BH interactions, our dynamical friction model captures the gradual inspiraling of orbits before the merger occurs. By contrast, the repositioning scheme, in its most classical renditions considered, describes extremely fast mergers, while the dynamical mass misrepresents the BHs' dynamics, introducing numerical scattering between the orbiting BHs. Given its performances in describing the centering of BHs within host galaxies and the orbiting of BH pair before their merging, our dynamical friction correction opens interesting applications for an accurate description of the evolution of BH demography within cosmological simulations of galaxy formation at different cosmic epochs and within different environments.info:eu-repo/semantics/acceptedVersionFil: Damiano, Alice.
