Firm, territory and local community: lessons learned from the Olivetti’s model
The paper discusses the relevance of the Olivetti model and the validity of that entrepreneurial experience based on values such as the concrete community, the territory and urban planning, and a source of virtuous learning to face the tensions of the current socio-economic systems. Through the methodology of the case study, the one developed by Adriano Olivetti is qualified as an arbor vitae business model: a model based on ethics and community, a culture of innovation and aesthetics in design. Thus, the Olivettian model of the arbor vitae is assumed as an ideal-typical model. It can assess the virtuosity or otherwise the possible corporate behavior in the current socio-economic contexts. The article ends by emphasizing the vast cultural heritage left by Olivetti to the city of Ivrea, the company’s headquarters. The Ivrea Olivetti factory became a virtuous model of work organization. It has made Ivrea as a smart land ante litteram conceived for man and not exclusively for the often dehumanizing efficiency of the assembly line. Olivetti factory in Ivrea became a model of a work organisation while the Ivrea community a smart land designed on the person and not on the dehumanized work of the assembly line: all these reasons have led Ivrea – the Industrial City of the 20th Century – to be recognized as the 54th Italian UNESCO Heritage. Il lavoro discute l’attualità del modello olivettiano e la validità di quell’esperienza imprenditoriale basata su valori quali la comunità concreta, il territorio e la pianificazione urbana e fonte di apprendimento virtuoso per affrontare le tensioni degli attuali sistemi socio-economici. Adottando la metodologia del caso di studio, quello sviluppato da Adriano Olivetti viene qualificato come modello di impresa arbor vitae: un modello fondato su etica e comunità, cultura dell’innovazione e dell’estetica nel design. Il modello olivettiano dell’arbor vitae viene così assunto a modello idealtipico sulla cui base valutare la virtuosità o meno dei possibili comportamenti d’impresa negli attuali contesti socio-economici. Il saggio si chiude sottolineando l’ingente eredità culturale lasciata da Olivetti alla città di Ivrea, sede dell’azienda. La fabbrica olivettiana di Ivrea divenne un modello virtuoso di organizzazione del lavoro e fece di Ivrea una smart land ante litteram concepita per l’uomo e non esclusivamente per l’efficienza, spesso disumanizzante, della linea di assemblaggio: proprio questa profondamente umana quanto illuminata concezione dello spazio lavorativo quale spazio innanzitutto di rapporto interumano è valsa ad Ivrea – Industrial City of the 20th Century – il prestigioso riconoscimento di 54° sito UNESCO italiano
Reflecting on hypertrophic plastic waste: concerns and levers
This paper intends to critically review the concerns and levers of the plastics management sector. Here we emphasise the need for seamless integration between all stages (production, consumption and recycling) of the plastics supply chain and the fundamental role played by the state as a promoter of coherent policies for sustainable development. The connection between pandemia and the current regulatory framework is thoroughly discussed
Surfing the complex interaction between new technology and norms: A resistance or resilience issue? Insights by the Viable System Approach (VSA)
The paper investigates the complex interaction between technological innovation and norms: a crucial dynamic to facing the severe challenges of the Anthropocene.On the one hand, the sedimentation of norms acts as the genetic memory of a society. Allowing a reduction in the uncertainty of human condition and ensuring greater predictability of human interaction, the set of norms tend to activate a system of constraints that normalize and legitimate technological innovations.On the other hand, technological innovation is one of the most unpredictable and non-linear sources of change. It demands legitimization for what in the past were excluded or prohibited a priori (e.g. behaviors, ethics): this may trigger a “decoupling” process from the extant set of norms. Nevertheless, what decoupling should be legitimized? A wicked problem arises, and forking paths emerge in the socio-economic landscape.Leading the tension between new technology (source of unpredictability) and the taken-for-granted norms (source of predictability) is crucial if the aim is to linking effectiveness and efficiency to viable sustainability. While the (still dominant) cartesian approach considers norms and new technology as separate elements of the social system, system thinking enlightens the interaction between them. This helps to unveil hidden options/feedbacks in the decoupling-recoupling process between technological innovation and the evolution of norms enriching the information variety of the decision-makers (policy makers, citizens, urban planners, etc.).The dynamics that govern this dyad, however, are not linear: norms, in fact, do not have the same reactivity to absorb (recouple) the change triggered by new technologies (decoupling from the extant set of norms).Although the relevance of the issue, it has been often neglected, or at least not taken in the right consideration. Therefore, aiming to investigate this dyadic relationship, the paper focuses on the ambiguous role technology plays in enabling resilience: sometimes it acts as a resilience amplifier; sometimes it is a resilience inhibitor (and even a steel cage); sometimes it provokes an undesirable deviation from the taken-for-granted codified rules.In particular, aiming to contribute in filling this gap, and rooting in the Viable System Approach (VSA), the paper investigates why and how in some cases the interaction between technological innovation and norms leads to resistance towards change or acts as a resilience amplifier in other cases.The paper is structured as follows: after an Introduction underlying the need to understanding the increasing tension between new technology and norms, Section 2 deals with the contribution of the VSA in understanding the social systems; then, rooting in the VSA and moving from the concept of information variety, Section 3 frames the complex interplay between new technology and taken-for-granted norms as one of the most dramatic “resistance-resilience” issue of the Anthropocene era; Section 4 proposes a more comprehensive framework discussing the range “resilience-resistance-vulnerability” and presents final reflections
From land to glass. An integrated approach for quality and traceability assessment of top Italian wines
The wine sector in Italy is a significant contributor to the country's economy. Furthermore, Italy is renowned for producing some of the world's most excellent wines. For these reasons, the wine industry is susceptible to frauds, such as reporting false origin claims in labels. In this context, this paper aims to provide traceability and quality tool to recognise wines from different Italian regions, i.e. Calabria, Piemonte, Sicily and Veneto, from selected winemakers that reach the Top 10% in almost three international rankings. The multi-elemental analysis of soil and wine samples by ICP-MS and their chemometric treatments have identified Ni, Cs, Li, Ca, Ba, Pb, Rb, Sb, Fe and U as the most informative variables to reach optimal classification of samples. The analytical data have been used to develop an original managerial framework to leverage Pareto's Principle for effective brand-land management in the top wine segment
A multi-analytical approach to studying the chemical composition of typical carbon sink samples
Peatlands in southern South America (Tierra del Fuego region, TdF) play a key role in the ecological dynamics of Patagonia. It is, therefore, necessary to increase our knowledge and awareness of their scientific and ecological value to ensure their conservation. This study aimed to assess the differences in the distribution and accumulation of elements in peat deposits and Sphagnum moss from the TdF. Chemical and morphological characterization of the samples was carried out using various analytical techniques, and total levels of 53 elements were determined. Furthermore, a chemometric differentiation based on the elemental content of peat and moss samples was performed. Some elements (Cs, Hf, K, Li, Mn, Na, Pb, Rb, Si, Sn, Ti and Zn) showed significantly higher contents in moss samples than in peat samples. In contrast, only Mo, S and Zr were significantly higher in peat samples than in moss samples. The results obtained highlight the ability of moss to accumulate elements and to act as a means to facilitate the entry of elements into peat samples. The valuable data obtained in this multi-methodological baseline survey can be used for more effective conservation of biodiversity and preservation of the ecosystem services of the TdF
Characterization of Italian honeys (Marche Region) on the basis of their mineral content and some typical quality parameters
<p>Abstract</p> <p>Background</p> <p>The characterization of three types of Marche (Italy) honeys (Acacia, Multifloral, Honeydew) was carried out on the basis of the their quality parameters (pH, sugar content, humidity) and mineral content (Na, K, Ca, Mg, Cu, Fe, and Mn). Pattern recognition methods such as principal components analysis (PCA) and linear discriminant analysis (LDA) were performed in order to classify honey samples whose botanical origins were different, and identify the most discriminant parameters. Lastly, using ANOVA and correlations for all parameters, significant differences between diverse types of honey were examined.</p> <p>Results</p> <p>Most of the samples' water content showed good maturity (98%) whilst pH values were in the range 3.50 – 4.21 confirming the good quality of the honeys analysed. Potassium was quantitatively the most relevant mineral (mean = 643 ppm), accounting for 79% of the total mineral content. The Ca, Na and Mg contents account for 14, 3 and 3% of the total mineral content respectively, while other minerals (Cu, Mn, Fe) were present at very low levels. PCA explained 75% or more of the variance with the first two PC variables. The variables with higher discrimination power according to the multivariate statistical procedure were Mg and pH. On the other hand, all samples of acacia and honeydew, and more than 90% of samples of multifloral type have been correctly classified using the LDA. ANOVA shows significant differences between diverse floral origins for all variables except sugar, moisture and Fe.</p> <p>Conclusion</p> <p>In general, the analytical results obtained for the Marche honeys indicate the products' high quality. The determination of physicochemical parameters and mineral content in combination with modern statistical techniques can be a useful tool for honey classification.</p
Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study
Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak.
Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study.
Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM.
Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide
Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector
A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world
Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.
Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.
Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.
Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.
Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
