Conservation agriculture systems: an economic viable solution experimented in a Mediterranean area of southern Italy

The global agro-food system is facing challenges that look at the hunger eradications, the control of global warming as well as the fair exploitation of terrestrial ecosystems. Therefore, it is necessary to define and implement a viable agricultural model, combining satisfaction of food needs and land preservation. A possible solution can be found in a holistic farming system consistent with a sustainable development model, designed to satisfy diverse “local” economies. The conservation agriculture (CA) can contribute to the management of agroecological systems including a set of best practices available to preserve agrarian soil and its biodiversity. After a brief background about recent CA experiences in Europe we provide, in a unique interpretative scheme, the evaluation of the impact of CA practices in terms of private/public interest, using the sustainability’s metric. We test the viability of a model based on CA in “local conditions”, we compare economic performance of different conservation practices (i.e. minimum and no tillage) to that of conventional agriculture in a typical Mediterranean environment - Collina Materana – in Southern Italy (Basilicata region). Our findings suggest that: i) CA can actually be a viable alternative to conventional systems and in particular no tillage is a useful tool to support rainfed agroecological systems in dry climates; ii) CA plays a role in terms of provision of public goods; iii) public support is needed to direct business choices

L'uso della crusca per promuovere circolarità nella filiera cerealicola

La produzione di cereali determina sprechi lungo tutta la filiera. Per ridurli è necessario ridefinire l’intero ciclo produttivo migliorandone l’efficienza e promuovendone la circolarità trovando nuove opportunità per output con un valore di mercato. A tal fine, attraverso l’Analisi Multi Criteriale (Amc) sono stati analizzati tre progetti alternativi per l’uso della crusca di grano (produzione di biogas, produzione di mangimi e produzione di carta) in Basilicata e Puglia. I risultati mostrano che promuovere la circolarità, in particolare usando la crusca per produrre biogas, è una soluzione efficiente per l’economia locale

Des-sexualización en la formación docente en Letras en la universidad: tensiones, conflictos y silencios a la hora de enseñar literatura en la escuela secundaria

desde la cátedra de Didáctica de la lengua y la literatura II en el Profesorado en Letras de nuestra facultad, venimos investigando durante estos últimos años cómo la apropiación de conocimiento específico en las clases de Prácticas del lenguaje y Literatura en escuelas secundarias de Ensenada y Berisso está sesgada y atravesada por conflictos vinculados con las sexualidades y los géneros y, a partir de notar un vacío en la formación de los docentes que ya están trabajando en el sistema provincial, estamos comenzando a indagar cómo se configura la formación docente en Letras en relación con esta problemática. De allí que, en este trabajo, nos proponemos abordar – a partir del análisis de fragmentos de registros tomados por cuatro docentes de la cátedra de una clase teórico-práctica de nuestra asignatura- cómo opera la des-sexualización (Lopes Louro, 1999) en la formación docente inicial como así también en vinculación con la intervención en el campo educativo, habida cuenta de que en nuestra asignatura los/as profesores/as en formación llevan adelante sus prácticas docentes.Eje 1: Cuerpos (in)disciplinados.Facultad de Humanidades y Ciencias de la Educació

Exploring urban gardening experiences in Europe and Asia: Rome vs. Tokyo

Nowadays the trend of urban gardening can be observed in many parts of the world. This phenomenon responds to the demand of rurality and the requalification of abandoned urban green areas expressed by city residents. Recently, many researchers have investigated about different types of urban gardening but mostly referring to English speaking developed countries (Guitart et al. 2012). To grasp the worldwide trend of urban gardening, this paper aims to compare urban gardening experiences in Rome and Tokyo. In Italy, the analysis is conducted through a direct investigation while the Japanese experience has been analysed through secondary data. The study of these two quite different metropolitan contexts helps to understand: (i) motivations on why urban residents need to grow food by themselves; (ii) types of ecosystem services (i.e. safeguard of agricultural land, food culture, production system, leisure model, environmental education, social cohesion) provided to stakeholders (Langemeyer et al. 2018; Speak et al. 2015). By comparing the two areas in Europe and Asia, we found urban residents’ interests in self-harvesting in common. Yet, there were differences in the form of urban gardening. Urban gardening in Rome is characterized by voluntary community activities, while Tokyo has commercial services to provide opportunities to not only those who have eagerness to grow vegetables, but also those who have less time and skills of growing plants

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe
