DISCOVERING THE EVERYDAY LANDSCAPE A cultural heritage education project in the urban periphery

Heritage and landscape education is crucial to training young people in active and responsible citizenship, protection of the public assets, appreciation of the cultural diversity and intergenerational dialogue. Therefore, it cannot be limited to sporadic experiences and on outstanding heritage and contexts but must be transdisciplinary, inclusive and practicable everywhere. This book relates the research and action project “Scuola Attiva Risorse” (ScAR), winner of the Polisocial Award that recognizes research for social purposes at the Politecnico di Milano. The text describes an experimental and innovative action delivered within the fragile context of the urban peripheries. This participatory process involved schools, universities, cultural institutions, administrations and private actors in interpreting and enhancing the “hidden” cultural heritage in Milan’s fringe neighbourhoods

Pan Africa business simulation games: The ITIS case study

Economists have demonstrated a positive correlation between management quality and the country's economic performance. In turn, business simulation games have shown their educational effectiveness in developing management skills crucial for African countries. However, its use is still nascent. Although they present different characteristics favorable to its implementation, for example, The African Continental Free Trade Area, the Digital Transformation Strategy Project for Africa (2020-2030), and The Pan-Africa Games Group, they also present singular characteristics such as the predominance of the informal sector, political instability, and high corruption rates. These factors influence the designing and adoption of the Pan-African Business Simulation Games Framework suitable for this specific context. This proposal aims to contribute a gaming framework to support collaborative development and appropriation by the end-users and Multi-User with content representative of their contextual diversity. The successful EVER project and Bootcamp created by the Mozambican firm ITIS, which adopted a lean startup methodology to add local content in Business Games, can inspire the Pan African Business Simulations Games - PABSG.info:eu-repo/semantics/acceptedVersio

Morphometric analysis of hepatocellular nodular lesions in HCV cirrhosis

Background and aims. We generated a computerized morphometric model to evaluate and quantify the morphological features in large regenerative nodules (LRN), high-grade dysplastic nodules (HGDN) and hepatocellular carcinoma (HCC). Methods. Sixteen LRN, 10 HGDN and 16 HCC in HCV-cirrhotic livers, were stained with H&E, smooth muscle actin, CD34, CD31 and reticulin to evaluate volume and surface fractions. Results. On H&E stains, the features most discriminatory between LRN, HGDN and HCC were volume fraction and number of hepatocytes nuclei in unit volume, and hepatocyte nuclear/cytoplasmic ratio. On immunohistochemistry, volume fractions of capillarised sinusoids, capillary units and isolated arteries were significantly different among all groups and highest in HCC; surface fraction of reticulin was markedly decreased in HCC. Conclusions. Our morphometric model is an objective method of quantification of the morphological changes of the nodular lesions and it could be applied in studies involving histological evaluation of the spectrum of nodular lesions arising in the cirrhotic liver

Localized inhibition of protein phosphatase 1 by NUAK1 promotes spliceosome activity and reveals a MYC-sensitive feedback control of transcription.

Deregulated expression of MYC induces a dependence on the NUAK1 kinase, but the molecular mechanisms underlying this dependence have not been fully clarified. Here, we show that NUAK1 is a predominantly nuclear protein that associates with a network of nuclear protein phosphatase 1 (PP1) interactors and that PNUTS, a nuclear regulatory subunit of PP1, is phosphorylated by NUAK1. Both NUAK1 and PNUTS associate with the splicing machinery. Inhibition of NUAK1 abolishes chromatin association of PNUTS, reduces spliceosome activity, and suppresses nascent RNA synthesis. Activation of MYC does not bypass the requirement for NUAK1 for spliceosome activity but significantly attenuates transcription inhibition. Consequently, NUAK1 inhibition in MYC-transformed cells induces global accumulation of RNAPII both at the pause site and at the first exon-intron boundary but does not increase mRNA synthesis. We suggest that NUAK1 inhibition in the presence of deregulated MYC traps non-productive RNAPII because of the absence of correctly assembled spliceosomes

Behavioural factors in the financial decisions of young Mozambicans

This paper seeks to analyse how behavioural factors influence the financial decisions of young Mozambican investors. The standard theory of finance assumes investors make rational financial decisions, seeking to minimise risk and maximise their expected utility. However, several studies have been conducted criticizing the assumption that investors are rational, opening the way to behavioural finance theory. According to the behavioural finance approach, financial decisions made by individuals are not based on rational thinking and their risk taking behaviour depends on their beliefs or feelings. Our analysis reveals that young Mozambicans are risk averse towards certain gains and risk lovers when faced with certain losses; they are excessively optimistic about the future; they use the information available as an anchor for their estimates; and they are so overconfident that they believe estimates in uncertain situations to be more accurate than they really are

Unusual skin toxicity associated with sustained disease response induced by nivolumab in a patient with non-small cell lung cancer

Introduction: Immunotherapy has shown efficacy in the treatment of different malignancies. Nivolumab, an immune checkpoint inhibitor directed against programmed death-1, has been approved for non-small cell lung cancer (NSCLC) in pretreated patients. Although it is generally well-tolerated, immunotherapy may be complicated by a wide range of immune-mediated adverse events. We describe the case of an uncommon skin toxicity arising as alopecia universalis induced by nivolumab in a patient with NSCLC. Case description: A 58-year-old man received nivolumab for metastatic NSCLC after progression to 3 lines of chemotherapy. The treatment was prescribed in June 2016, and induced a rapid and significant disease response. Nivolumab was well-tolerated until May 2017, when partial alopecia at hair and eyelashes appeared. In the next months, alopecia became complete and extended to the whole body surface. The dermatologic picture was compatible with alopecia areata. A topical steroid therapy was attempted, without benefit. The patient refused systemic treatments and is still undergoing nivolumab without new toxicities and with persistent disease response. Conclusions: This case suggests that alopecia areata may be a rare immune-related adverse event of immune checkpoint agents. Its late onset in our patient is uncommon and unexpected, underlining that the risk of nivolumab-induced toxicity is not limited to the beginning of treatment. Despite its rarity, alopecia areata should be considered in the range of adverse events potentially induced by immune checkpoint inhibitors even in the long term. Potential association between toxicity and efficacy of immunotherapy in NSCLC warrants further investigation

Schwarz type preconditioners for the neutron diffusion equation

[EN] Domain decomposition is a mature methodology that has been used to accelerate the convergence of partial differential equations. Even if it was devised as a solver by itself, it is usually employed together with Krylov iterative methods improving its rate of convergence, and providing scalability with respect to the size of the problem. In this work, a high order finite element discretization of the neutron diffusion equation is considered. In this problem the preconditioning of large and sparse linear systems arising from a source driven formulation becomes necessary due to the complexity of the problem. On the other hand, preconditioners based on an incomplete factorization are very expensive from the point of view of memory requirements. The acceleration of the neutron diffusion equation is thus studied here by using alternative preconditioners based on domain decomposition techniques inside Schur complement methodology. The study considers substructuring preconditioners, which do not involve overlapping, and additive Schwarz preconditioners, where some overlapping between the subdomains is taken into account. The performance of the different approaches is studied numerically using two-dimensional and three-dimensional problems. It is shown that some of the proposed methodologies outperform incomplete LU factorization for preconditioning as long as the linear system to be solved is large enough, as it occurs for three-dimensional problems. They also outperform classical diagonal Jacobi preconditioners, as long as the number of systems to be solved is large enough in such a way that the overhead of building the pre-conditioner is less than the improvement in the convergence rate.
