L’educazione all’imprenditorialità in contesti cooperativi

Il presente contributo illustra un laboratorio cooperativo nella formazione tecnica tra scuola ed esperienza lavorativa volto alla risoluzione dei problemi che gli studenti hanno quando attraversano i confini. Tale laboratorio è costruito su un modello socioculturale e riunisce studenti, insegnanti e tutor lavorativi per trovare soluzioni condivise. L’agency collettiva mobilitata durante la discussione qualifica la competenza chiave europea per l’apprendimentopermanente relativa al senso d’iniziativa e d’imprenditorialità:gli studenti trovano soluzioni condivise e le mettono in essere durante un ciclo di apprendimento espansivo che genera innovazione

Laboratorio di contrasto alla dispersione: risultati di un progetto negli istituti mantovani

This article shows results of a pilot study carried out during school year2013-2014 to contrast school leaving in Mantua, in the Lombardy region. Inline with Europe 2020 objectives, the aim was to experiment new methodologiesable to reduce the phenomenon of school leaving during grade IVof high school. Although with different modalities, in three institutes ofMantua work experience and contemporaneous weekly boundary crossingworkshops were provided. In the workshops participated the selected students,teachers and representatives of industry. Over the workshops thegroups discussed the issues students were having between school andwork and topics concerning entrepreneurship. Results show improvementsin the indicators chosen to represent the students’ intention to continuetheir studies, but with substantial differences according to the setting. However,a common worry emerging from this research is that half of the studentsdeclared that they have at least one teacher that they cannot stand.Il presente contributo illustra i risultati di una ricerca effettuata nell’anno scolastico2013-2014 per contrastare la dispersione scolastica nella provincia diMantova. In linea con gli obiettivi di Europa 2020, l’obiettivo era quello di introdurrenuove metodologie educative basate sull’insegnamento dell’imprenditorialitàvolte a ridurre la dispersione scolastica al quarto anno di studi superiori.Nei tre istituti mantovani partecipanti, seppure con modalità diverse, sisono organizzati dei periodi di alternanza scuola lavoro con contemporaneilaboratori settimanali di attraversamento dei confini a cui hanno partecipatoinsegnanti, rappresentanti del mondo del lavoro e gruppi selezionati di studenti.Durante i laboratori si sono discussi sia i problemi degli studenti trascuola e lavoro che le tematiche relative all’imprenditorialità. I risultati mostranoavanzamenti nel contrasto della dispersione che variano a seconda del settingdove si è operato. Un elemento comune ad ogni contesto e che desta preoccupazioneè che metà degli gli studenti che hanno partecipato alla ricercadichiarano che hanno almeno un professore che non sopportano.

Nella mia scuola nessuno è straniero L’educazione all’intercultura attaverso il metodo Feuerstein

This article is about an experience of cultural integration within the so called “Learning Week projects” sponsored by the Lombardia Region, Italy.The residential workshop held close to the Garda Lake in September 2011 was promoted by the high school Arco d’Este of Mantua. The participants where thirty students aged 16-18, half of them Italian and half immigrants of first or second generation. Some of their teachers participated as mentors.The activities consisted on the cognitive enhancement of the participants through Feuerstein Instrumental Enrichment, and on an activity centred on body awareness and story telling. Among the criteria of mediation used in the workshop, a particular importance was given to the sharing behaviour. Important support for our work is found in Touraine and Morin’s thoughts.Our claim is that the environment we set up through Mediated Learning Experience realizes Raffaghelli’s idea of learning within multicultural enlarged environment, fits Sterberg’s suggested way to teach intelligence in the classroom and Demetrio’s transcultural education. Eventually, the results in terms of students and teachers’ appreciation are discussed, also in term of reduction of prejudice.L’articolo inizia illustrando che cosa sono i percorsi Learning Week, e procede con le basi teoriche dell’intervento: da un lato sono spiegati l’inquadramento teorico dello stereotipo e del pregiudizio; successivamente si analizza il metodo Feuerstein usato nell’intercultura, nonché la mediazione e gli strumenti utilizzati nell’intervento. Nelle conclusioni si cerca di allargare il focus dell’intervento collegandolo con il pensiero di Touraine e Morin,e collegando l’ambiente realizzato tramite la mediazione Feuerstein all’apprendere in ambienti culturali allargati di Raffaghelli, all’insegnare l’intelligenza in classe di Sternberg, ed a all’educazione transculturale di Demetrio

Tunnel Inflow Monitoring in Permeable Rocks Nearby Cannero River, Piedmont (Northern Italy)

Analytical methods used in engineering practice for a preliminary tunneling design do not adequately account for the domain limitation due to a river. In order to forecast the flow rate that has to be extracted to reach a sustainable water head in tunnel, the design must consider the changes of river hydrometric level and their consequences on piezometric head. The river is taken in account and the constraints of analytical solutions are discussed assuming isotropic and infinite domain. In particular, the study develops a formulation considering the variation of hydrograph in the river and different location of tunnel in the aquifer nearby the stream. Then, this equation was applied to a preliminary tunneling design in Cannero Valley, Northern Italy (Piedmont). The results, compared with analytical model's ones show that the analytical approach leads to a good estimation of the tunnel inflow and, the analytical to a preliminary evaluation of its most suitable location

Bovine Colostrum Supplementation Modulates the Intestinal Microbial Community in Rabbits

Simple Summary Recently, research has focused on the modulation of the gut microbiota because of its central role in several digestive physiological functions and its involvement in the onset of not only gastrointestinal but also systemic diseases. Supplementing rabbit diets with nutraceutical substances could be a strategy to prevent dysbiosis, strengthen the immune system, and reduce mortality during the critical weaning period. Bovine colostrum (BC) is a by-product of the dairy industry and is very rich in compounds with several biological activities. Its use as an intestinal microbiota modulator in rabbits has never been investigated. This study evaluates the effects of diet supplementation with two different percentages of BC (2.5 and 5%) on luminal and mucosa-associated microbiota and its metabolism-associated pathways in the jejunum, caecum, and colon of rabbits. Although our results showed no effect of BC on microbiota biodiversity, there were significant differences between experimental groups in the microbial composition, mainly at the level of sub-dominant components depending on the dose of supplementation. The metabolism-associated pathways have also been affected, and particularly interesting are the results on the amino acids and lactose metabolism. Overall, findings suggest that BC could be used as a supplement in rabbit feed, although its effects on productive and reproductive performances, intestinal disease resistance, and economic aspects need to be further evaluated. BC is a nutraceutical that can modulate intestinal microbiota. This study investigates the effects of BC diet supplementation on luminal and mucosa-associated microbiota in the jejunum, caecum, and colon of rabbits. Twenty-one New Zealand White female rabbits were divided into three experimental groups (n = 7) receiving a commercial feed (CTRL group) and the same diet supplemented with 2.5% and 5% BC (2.5% BC and 5% BC groups, respectively), from 35 (weaning) to 90 days of age (slaughtering). At slaughter, the digestive tract was removed from each animal, then both content and mucosa-associated microbiota of jejunum, caecum, and colon were collected and analysed by Next Generation 16SrRNA Gene Sequencing. Significant differences were found in the microbial composition of the three groups (i.e., beta-diversity: p < 0.01), especially in the caecum and colon of the 2.5% BC group. The relative abundance analysis showed that the families most affected by the BC administration were Clostridia UCG-014, Barnesiellaceae, and Eggerthellaceae. A trend was also found for Lachnospiraceae, Akkermansiaceae, and Bacteroidaceae. A functional prediction has revealed several altered pathways in BC groups, with particular reference to amino acids and lactose metabolism. Firmicutes:Bacteroidetes ratio decreased in caecum luminal samples of the 2.5% BC group. These findings suggest that BC supplementation could positively affect the intestinal microbiota. However, further research is needed to establish the optimal administration dose

High–temporal resolution profiling reveals distinct immune trajectories following the first and second doses of COVID-19 mRNA vaccines

Knowledge of the mechanisms underpinning the development of protective immunity conferred by mRNA vaccines is fragmentary. Here, we investigated responses to coronavirus disease 2019 (COVID-19) mRNA vaccination via high–temporal resolution blood transcriptome profiling. The first vaccine dose elicited modest interferon and adaptive immune responses, which peaked on days 2 and 5, respectively. The second vaccine dose, in contrast, elicited sharp day 1 interferon, inflammation, and erythroid cell responses, followed by a day 5 plasmablast response. Both post-first and post-second dose interferon signatures were associated with the subsequent development of antibody responses. Yet, we observed distinct interferon response patterns after each of the doses that may reflect quantitative or qualitative differences in interferon induction. Distinct interferon response phenotypes were also observed in patients with COVID-19 and were associated with severity and differences in duration of intensive care. Together, this study also highlights the benefits of adopting high-frequency sampling protocols in profiling vaccine-elicited immune responses

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
