Dirac equation in terms of hydrodynamic variables

description: The distributed system $\mathcal{S}_D$ described by the Dirac equation is investigated simply as a dynamic system, i.e. without usage of quantum principles. The Dirac equation is described in terms of hydrodynamic variables: 4-flux $j^{i}$, pseudo-vector of the spin $S^{i}$, an action $\hbar ϕ$ and a pseudo-scalar $κ$. In the quasi-uniform approximation, when all transversal derivatives (orthogonal to the flux vector $j^i$) are small, the system $\mathcal{S}_D$ turns to a statistical ensemble of classical concentrated systems $\mathcal{S}_{dc}$. Under some conditions the classical system $\mathcal{S}_{dc}$ describes a classical pointlike particle moving in a given electromagnetic field. In general, the world line of the particle is a helix, even if the electromagnetic field is absent. Both dynamic systems $\mathcal{S}_D$ and $\mathcal{S}_{dc}$ appear to be non-relativistic in the sense that the dynamic equations written in terms of hydrodynamic variables are not relativistically covariant with respect to them, although all dynamic variables are tensors or pseudo-tensors. They becomes relativistically covariant only after addition of a constant unit timelike vector $f^{i}$ which should be considered as a dynamic variable describing a space-time property. This "constant" variable arises instead of $γ$-matrices which are removed by means of zero divizors in the course of the transformation to hydrodynamic variables. It is possible to separate out dynamic variables $κ$, $κ^i$ responsible for quantum effects. It means that, setting $κ,κ^i\equiv 0$, the dynamic system $\mathcal{S}_D$ described by the Dirac equation turns to a statistical ensemble $\mathcal{E}_{Dqu}$ of classical dynamic systems $\mathcal{S}_{dc}$.

Inside the Ensete Garden, Beyond the Plantation

description: Against a backdrop of increasingly simplified ecologies—in the form of plantation and monocultural thinking—this article elaborates a call to radical change in sustainable food systems as being fostered by multispecies assemblages and rooted in a less anthropocentric vision of farming practices and the natural environment. Multiplicity in practice (and as a philosophical guiding principle in the quest for sustainable food systems) is analyzed through the lens of edible perennials and the functional role they play in specific integrated farming systems. The analysis starts from the case study of a perennial root tuber crop in Southwestern Ethiopia, and further expands into the related ramifications of home gardening, polycultural farming, multistoried landscapes, and integrated agriculture. This multilayered story then branches out from the Ethiopian home garden to touch upon the broader category of improved agroforestry practices, which are based on solid and ecologically sound perennial components. It is argued that multifunctional mosaics hold untapped potential to address the call for sustainable food systems in times of profound socio-natural crisis. A bold paradigm shift sustains this vision—from plantations back to forest-like intricacies.

Tectonic Implications of Erosional and Depositional Features in Upper Meramecian and Lower Chesterian (Mississippian) Rocks of South-Central and East-Central Kentucky

description: Abstract:
Erosional and depositional features in upper Meramecian and lower Chesterian (Mississippian) carbonate rocks of south-central and east-central Kentucky suggest the influence of coeval structural activity. The study area, which extends from Pulaski County northeastward into Powell County, is underlain by (1) the Greenwood Anomaly, a large north-trending gravity anomaly, which probably represents part of a Precambrian rift system, and (2) the western part of the Rome Trough, an east-trending graben-like structure, which represents a Late Precambrian to Cambrian continental rift zone. The study focused on the St. Louis Limestone and lower Monteagle Limestone of south-central Kentucky and correlative carbonate rocks of the Slade Formation in east-central Kentucky.
Several lines of evidence suggest Mississippian reactivation of rift-related faults associated with the Greenwood Anomaly and the Grenville Front, which extends along the west side of the anomaly: (1) local subaerial exposure of St. Louis sediments, (2) local depositional thinning of lower Monteagle sediments, (3) relatively widespread erosion during early Monteagle time, and (4) thickness variation in Mississippian units across the anomaly.
In east-central Kentucky, erosional and depositional features suggest Mississippian movement along the Locust Branch and Glencairn Faults of the Irvine-Paint Creek Fault System in the interior of the Rome Trough during deposition of the Slade Formation. Reactivation along the projected trend of the Locust Branch Fault in Estill and Jackson Counties apparently resulted in (1) abrupt thinning of the Renfro Member, (2) penecontemporaneous soft-sediment deformation of Big Sinking bed deposits, and (3) extensive erosion of the Burnside member. Movement along the Glencairn Fault in Powell and Wolfe Counties is indicated by more pronounced erosion of the Burnside member along the border of the upthrown side.
Mississippian reactivation of faults apparently was caused by migration of lithospheric bulges through the area. Based on recent investigations that relate Mississippian depositional sequence to lithospheric flexure, passage of an east-migrating, relaxation-phase, Acadian bulge and a north-migrating Ouachita bulge seems to have been contemporaneous with the fault movements and may explain evidence of fault reactivation and its consequences on Mississippian carbonate deposition in the area.

description: The electron-electron interaction quantum correction to the conductivity of the gated double well Al$_x$Ga$_{1-x}$As/GaAs structures is investigated experimentally. The analysis of the temperature and magnetic field dependences of the conductivity tensor allows us to obtain reliably the diffusion part of the interaction correction for the regimes when the structure is balanced and when only one quantum well is occupied. The surprising result is that the interaction correction does not reveal resonant behavior; it is practically the same for both regimes.

Hybridization of Food Spaces
Creators: name: Fodor, Kata
Publisher: name: The International Journal of Sociology of Agriculture and Food
Year: 2021

description: On the consumption end of the food supply chain, cities have leverage to spatially facilitate sustainable food system transformations and accommodate sustainable diets. However, developing the appropriate architecture implied in such a feat, i.e., creating the adequate spatial conditions for sustainable urban food practices, is first predicated on understanding the existing spatial logics operating at the core of contemporary urban food practices and food spaces. This paper aims to contribute to this understanding, by identifying and conceptualising some of these changing spatial logics. Through a series of observations across four domains - cyberspace, retail spaces, the domestic realm and compound food spaces – the study finds that several 21st-century constructs, such as online food purchasing, the connected kitchen or the diversified supermarket, exhibit entirely novel spatial logics in organising urban food practices and the physical reality around them. As a key finding of the analyses, this paper introduces the term ‘hybridization of food spaces’, linking two overarching patterns identified: how 21st-century urban food space typologies increasingly show signs of functional diversification in their physical layouts, as well as ways of merging with virtual platforms. Finally, the paper considers the design and strategic potential that this hybridization presents. How blurring the boundaries between traditionally conceived spatial/functional domains, as well as shortening urban food supply chains may contribute to the physical facilitation of sustainable urban practices around food, and ultimately, sustainable diets.

Surplus food redistribution and healthy sustainable diets

Year: 2021

description: A substantial body of literature points to the necessity of a ‘Great Food Transformation’ requiring an urgent shift towards sustainable food systems across multiple levels. A key part of this transition is the need to reduce food waste and food loss by 50 percent and where charitable surplus food redistribution is regarded as making an important contribution to this target. Surplus driven charitable food provisioning is now part of the food environment in many countries and is influencing the diets of a significant number of people. Its proponents argue that such work contributes to a more sustainable food system by reducing food waste and food insecurity. However, few studies have examined the factors influencing the governance of food within the charitable food system. This paper seeks to fill this gap in the literature through an examination of recent developments in charitable food provisioning in the Republic of Ireland. Using Cork city as a case study we explore Ireland’s charitable food system by examining the motivations, ideas, and practices of key organisations. The paper highlights the growing role of surplus-driven charitable food systems and argues that the redistribution of surplus products for the purpose of reducing food waste and improving economic efficiency requires re-evaluation within a wider appreciation of sustainable diets, and, ultimately, with regard to strengthening the right to food for all.

A cfd-dem approach to study the hydrodynamics of solid-liquid mixing in vertical stirred mills using dynamic mesh
Creators: name: Joseph, Bibin
Publisher: name: University of British Columbia
Year: 2022

description: In mineral processing industries, stirred media mills are known for achieving smaller particle size and better energy intensity in comminution. The mill consists of a rotating shaft driving discs, pins, or skews known as a stirrer powered by a motor coupled outside the mill chamber. The rotating shaft transmits the kinetic energy to the grinding media. Every mineral has its distinctive physical properties, making it hard to create general standards to cover all materials that the stirred media mills might process. Therefore, to address specific applications, different stirred media mills were built with varying stirrer designs. The mill’s performance improvements are complicated, which are related to grinding and energy efficiency, because of the lack of flow profiles inside the system, which vary based on the stirrer shapes. The lack of flow profiles is due to the high-density slurry media flow, which complicates the enhancement of stirred mills performance. However, it is necessary to increase the comminution efficiency in stirred media mills to reduce its power consumption. To overcome these flow monitoring issues, the grinding mechanisms, and fluid-particles flow mixtures for a better understanding, numerical models are commonly used in smaller particle sizes. In this study, slurry and grinding media suspension behaviour are captured using a multi- phase computational model. Media particle collisions with each other and walls are solved numerically using Discrete Element Method (DEM), while single-phase slurry flow is simulated using Computational Fluid Dynamics (CFD) and the combined effects are established through coupling these numerical methods. Media particles’ grinding efficiency is estimated using stress intensity generated by particle collision. This study focuses on developing and validating a high- performance multi-scale numerical model to simulate agitated stirred mills filled with granular media and slurry. Also, the effects of operating and design parameters on the hydrodynamics of the system and particle breakage is considered for efficiency optimization. The proposed high-fidelity CFD-DEM numerical approach with dynamic meshing helps to understand the fluid-particle flow behaviour inside the mill and optimize the design parameters for performance improvements of VXPmills, which leads to the evolution of a new design with enhanced grinding efficiency with less torque.

description: The magnetic fields affect collapse of molecular cloud cores. Here, we consider a collapsing core with an axial magnetic field and investigate its effect on infall of matter and formation of accretion disk. For this purpose, the equations of motion of ions and neutral infalling particles are numerically solved to obtain the streamlines of trajectories. The results show that in non-steady state of ionization and ion-neutral coupling, which is not unexpected in the case of infall, the radius of accretion disk will be larger as a consequence of axial magnetic field.

description: We use the recent measurement of the velocity dispersion of star-forming, outer-disk knots by Herbert-Fort et al. in the nearly face-on galaxy NGC 628, in combination with other data from the literature, to execute a straightforward test of gravity at low accelerations. Specifically, the rotation curve at large radius sets the degree of non-standard acceleration and then the predicted scaleheight of the knots at that radius provides the test of the scenario. For our demonstration, we presume that the H alpha knots, which are young (age < 10 Myr), are distributed like the gas from which they have recently formed and find a marginal (> 97% confidence) discrepancy with a modified gravity scenario given the current data. More interestingly, we demonstrate that there is no inherent limitation that prevents such a test from reaching possible discrimination at the > 4 sigma level with a reasonable investment of observational resources.

Constructing a food retail environment that encourages healthy diets in cities: the contribution of local-level policy makers and civil society
Creators: name: Mattioni, Dalia
Publisher: name: The International Journal of Sociology of Agriculture and Food
Year: 2021

description: Faced with growing rates of malnutrition, food environments play a key role in shaping eating habits and in helping transition towards healthy diets. Much of the attention on food environment policies has been directed at the national level. Less attention has been devoted to what happens at local level, at the measures being taken by local government policy makers and by other local-level actors to encourage healthier diets, especially in cities. The objective of this article is thus to give an overview of the contribution “from below” to the construction of healthier food environments, that is, to shed light on the specific contribution of local-level policies and initiatives in making nutritious food more available, affordable, and desirable and conversely in making unhealthy foods, such as fast foods and ultra-processed foods, less so. In doing so, it focuses on the retail food environment (RFE) as a specific contribution of cities. A critical review of evaluated local-level policies sheds light on the nature and effectiveness of different types of interventions and on the complementary actions of local government and civil society, where the latter contributes to communicating a different way of “knowing” food in line with a greater appreciation of healthier foods, and to advocating for an integration of sustainability aspects in the transition towards healthy diets. The article reflects upon areas where further efforts and adjustments are needed to make interventions more effective, and emphasizes the need to continue supporting local-level civil society RFE actions, and ensure coordination and coherence between different players and between different administrative levels.

description: In our previous reports, an endophytic bacterium, Bacillus cereus KP120 was isolated from the halophyte species Kosteletzkya virginica. In this study, the effect of KP120 colonization on Arabidopsis thaliana seedlings was investigated. Our results showed that inoculation with KP120 could promote the growth of A. thaliana seedlings plants under salt-stress conditions, compared with uninoculated controls. After salt treatment, chlorophyll, proline, the activity of antioxidant enzymes, Indole-3-acetic acid and 1-aminocyclopropane-1-carboxylate-deaminase in plants inoculated were increased significantly but malondialdehyde content was decreased compared with the plants under salt stress lonely. Similarly, under non-salt stress, physiological indices above except for MDA in plants inoculated with KP120 were increased compared with control. B. cereus also induced the up-regulation of key genes involved in IAA biosynthesis, responses, transport, down-regulated expression of genes related with ethylene synthesis and response. Our work principally demonstrates that Bacillus cereus KP120 significantly enhances plant growth and increases plant tolerance to salt stress.

description: As national borders tighten against undocumented migrants, agricultural employers throughout North America have pushed governments for easier access to a legalized temporary farm workforce. Some U.S. farmers and policymakers are seeking to expand the country’s temporary agricultural guest worker program (H-2A visa). Canada’s longstanding Seasonal Agricultural Worker Program has been proposed on an international scale as an example of best practices because it fulfills employer demands for a stable workforce, enables state control over migration flows and, at least on paper, safeguards workers’ rights. However, researchers have documented systemic violations of workers’ rights in both countries. How do outcomes for legalized temporary migrant farmworkers in Canada compare to those in the United States? This paper addresses an empirical gap in the literature by rigorously comparing agricultural guest worker programs in Canada and the United States. We analyze how guestworker immigration policies shape migration flows, along with employment and well-being outcomes for agricultural workers. Ultimately, we argue that programs in both countries function by creating an unfree workforce. Despite differences in the policy environment and structure of the programs, they present similar outcomes of systemic precarity for participating workers.

Two interacting Ising chains in relative motion

description: We consider two parallel cyclic Ising chains counter-rotating at a relative velocity v, the motion actually being a succession of discrete steps. There is an in-chain interaction between nearest-neighbor spins and a cross-chain interaction between instantaneously opposite spins. For velocities v>0 the system, subject to a suitable markovian dynamics at a temperature T, can reach only a nonequilibrium steady state (NESS). This system was introduced by Hucht et al., who showed that for v=\infty it undergoes a para- to ferromagnetic transition, essentially due to the fact that each chain exerts an effective field on the other one. The present study of the v=\infty case determines the consequences of the fluctuations of this effective field when the system size N is finite. We show that whereas to leading order the system obeys detailed balancing with respect to an effective time-independent Hamiltonian, the higher order finite-size corrections violate detailed balancing. Expressions are given to various orders in 1/N for the interaction free energy between the chains, the spontaneous magnetization, the in-chain and cross-chain spin-spin correlations, and the spontaneus magnetization. It is shown how finite-size scaling functions may be derived explicitly. This study was motivated by recent work on a two-lane traffic problem in which a similar phase transition was found.

description: Using the Torus radiative transfer code we produce synthetic observations of the 21 cm neutral hydrogen line from an SPH simulation of a spiral galaxy. The SPH representation of the galaxy is mapped onto an AMR grid, and a ray tracing method is used to calculate 21 cm line emission for lines of sight through the AMR grid in different velocity channels and spatial pixels. The result is a synthetic spectral cube which can be directly compared to real observations. We compare our synthetic spectral cubes to observations of M31 and M33 and find good agreement, whereby increasing velocity channels trace the main disc of the galaxy. The synthetic data also show kinks in the velocity across the spiral arms, evidence of non-circular velocities. These are still present even when we blur our data to a similar resolution as the observations, but largely absent in M31 and M33, indicating those galaxies do not contain significant spiral shocks. Thus the detailed velocity structure of our maps better represent previous observations of the grand design spiral M81.

description: The practice of saving seeds from local varieties of crops and vegetables is integral for preserving agricultural biodiversity. After reviewing the current (1) seed saving activities practiced worldwide, (2) agricultural industry and farmer behaviour in Japan, and (3) seed system used in Japan, we conducted a survey to determine methods for the cultivation of homegrown seeds on a regional scale. Questionnaires were mailed to 7,068 families (including full-time and part-time farmers and home gardeners) in the Noto Peninsula, Ishikawa Prefecture, Japan, and 1,662 responses were obtained. We found that a majority of the respondents purchased seeds; however, some seeds were grown locally, and were mostly homegrown. Contrary to general expectations, the economic incentive (“good market price”) played an insignificant role in crop cultivation continuity. Cluster analysis resulted in four groups of crops, according to the rate of on-farm seed saving and changes in cultivation over a 30-year period. Certain crops, such as soybean and azuki bean, were frequently grown using on-farm produced seeds. Different conservation strategies were required for crops in each cluster due to their unique characteristics. Our data form the basis for promoting diversity and local crop cultivation by farmers in industrialized countries.

description: Societal change is reflected in food consumption habits. In postindustrial societies consumers are increasingly emphasizing health, ethical, and ecological aspects in their consumption habits. This study investigated the changes in food consumption in Finland during 1985?2016. Fruits and berries, vegetables, and fish were used as indicators of healthy and contemporary food habits. To untangle the dynamics of change, time series data of Finnish household budget surveys from 1985 to 2016 and novel age-period-cohort models were used. The share of total food expenditure of all examined foods increased during the study period. Increasing vegetable and fruit consumption was reflected in the younger birth cohorts consuming more than the preceding ones. The food expenditure shares of fruit, berries, and fish were highest and rose most in over-50 age groups. However, the food expenditure shares of vegetables, and fruit and berries also rose in younger age groups during the most recent period. Cohort differences could not be explained by rising incomes, educational level or urbanization.

description: Se trasformassimo le lettere in immagini tipografiche risulterebbero agli occhi di un bambino più facili da apprendere, così come decidere di servirsi di un sistema di apprendimento ludico e sperimentale con strumenti in grado di attivare la creatività e mantenere viva la voglia di non smettere mai di imparare. Tutto il mio percorso è cominciato analizzando le differenti metodologie didattiche impiegate nelle scuole elementari riguardanti l’apprendimento della scrittura e lettura delle lettere dell’alfabeto, così da avere una visione più mirata riguardo agli strumenti e ai supporti impiegati dai docenti. Non avendo riscontrato un sistema ben definito mi sono posta un obiettivo, ovvero cercare di rendere piacevole e funzionale l’esperienza del bambino durante l’apprendimento dell’alfabeto, nell’intento di sensibilizzarlo visivamente attraverso degli strumenti comunicativi di qualità.

description: We study the gauge sector of Minimal Walking Technicolor, which is an SU(2) gauge theory with nf=2 flavors of Wilson fermions in the adjoint representation. Numerical simulations are performed on lattices Nt x Ns^3, with Ns ranging from 8 to 16 and Nt=2Ns, at fixed β=2.25, and varying the fermion bare mass m0, so that our numerical results cover the full range of fermion masses from the quenched region to the chiral limit. We present results for the string tension and the glueball spectrum. A comparison of mesonic and gluonic observables leads to the conclusion that the infrared dynamics is given by an SU(2) pure Yang-Mills theory with a typical energy scale for the spectrum sliding to zero with the fermion mass. The typical mesonic mass scale is proportional to, and much larger than this gluonic scale. Our findings are compatible with a scenario in which the massless theory is conformal in the infrared. An analysis of the scaling of the string tension with the fermion mass towards the massless limit allows us to extract the chiral condensate anomalous dimension γ*, which is found to be γ*=0.22+-0.06.

description: In this paper, we construct and study a mathematical model of a suspended microchannel resonator (SMR) resonator with an electrostatic principle of actuation, designed to determine the mass of nanoparticles located in the fluid flowing through the channel of the resonator. The problem of small oscillations of a resonator in the vicinity of a non-trivial equilibrium state is investigated. The dependence of the natural frequencies of the resonator on the flow rate of the liquid, the magnitude and location of the nanoparticle in the channel, the strength of the electric field is determined. The problem of elastic stability of a resonator is investigated in the presence of non-conservative forces. An algorithm is proposed for determining the mass of a nanoparticle from the recorded changes in the spectral properties of the system.
Can cross-linguistic regularities be explained by constraints on change?
Creators: name: Haspelmath, Martin
Publisher: name: Zenodo
Year: 2019

description: This paper addresses a recent trend in the study of language variation and universals, namely to attribute cross-linguistic patterns to diachrony, rather than to other causal factors. This is an interesting suggestion, and I try to make the basic concepts clearer, by distinguishing clearly between language-particular regularities, universal tendencies, and mere recurrent patterns, as well as three kinds of causal factors (preferences, constraints, restrictions). I make four claims: (i) Explanations may involve diachrony in different ways; (ii) for causal explanations of universal tendencies, one needs to invoke mutational constraints (change constraints); (iii) in addition to mutational constraints, we need functional-adaptive constraints as well, as is clear from cases of multi-convergence; and (iv) successful functional-adaptive explanations do not depend on understanding the precise pathways of change.
Star Formation Efficiencies and Lifetimes of Giant Molecular Clouds in the Milky Way
Creators: name: Murray, Norman
Publisher: name: arXiv
Year: 2010
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We use a sample of the 13 most luminous WMAP Galactic free-free sources, responsible for 33% of the free- free emission of the Milky Way, to investigate star formation. The sample contains 40 star forming complexes; we combine this sample with giant molecular cloud (GMC) catalogs in the literature, to identify the host GMCs of 32 of the complexes. We estimate the star formation efficiency epsilon_GMC and star formation rate per free-fall time epsilon_ff. We find that epsilon_GMC ranges from 0.002 to 0.2, with an ionizing luminosity-weighted average epsilon_GMC = 0.08, compared to the Galactic average = 0.005. Turning to the star formation rate per free-fall time, we find values that range up to epsilon_ff = 1. Weighting by ionizing luminosity, we find an average of epsilon_ff = 0.16 - 0.24 depending on the estimate of the age of the system. Once again, this is much larger than the Galaxy-wide average value epsilon_ff = 0.008. We show that the lifetimes of giant molecular clouds at the mean mass found in our sample is 17 plus or minus 4 Myr, about two free-fall times. The GMCs hosting the most luminous clusters are being disrupted by those clusters. Accordingly, we interpret the range in epsilon_ff as the result of a time-variable star formation rate; the rate of star formation increases with the age of the host molecular cloud, until the stars disrupt the cloud. These results are inconsistent with the notion that the star formation rate in Milky Way GMCs is determined by the properties of supersonic turbulence

Theory, Epistemology and Critical Rural Sociology
Creators: name: Bonanno, Alessandro
name: E. Swanson, Louis
Publisher: name: The International Journal of Sociology of Agriculture and Food
Year: 2021

description: This paper would like to provide an alternative to the Marx-Weber dichotomy which has recently emerged in rural sociological studies. It consists of the re-proposition of critical sociology as a mode of scientific investigation which, while remaining within the Marxian tradition, addresses many of the central concerns of Weberian scholarship. Though a merger between Marx and Weber is not proposed, it is assumed that a lack of knowledge of critical sociology has hampered further development of the theoretical debate in rural sociology. More importantly, this lack of knowledge has prevented the diffusion of the basic tenets of critical sociology among sociologists concerned with the study of agriculture and food, limiting their ability to inform empirical investigations and to instruct students. Resumen Teoría Crítica, Epislemología y Sociología Rural Este trabajo trata de proveer una alternativa a la dicotomia Marx-Weber que recientemente a emergido en los estudios sociológicos rurales. Consiste en una re-proposición de la sociología crítica como un modo de investigación científica que, aún permaneciendo dentro de la tradición marxista, puede dirigirse a muchos aspectos concernientes al saber Webweriano. Aunque una integración entre Marx y Weber no es propuesta, se parte del supuesto de que una falta de conocimeinto de sociología crítica tiende a estorbar el fomento y desarrollo del debate teórico en sociología rural. Mas importantemente, esta falta de conocimiento ha trabado la difusión de los fundamentos básicos de la sociología crítica entre sociólogos que se ocupan de los estudios de la agricultura y alimentos, limitando la información de la investigación empírica y la enseñanza a los estudientes.

Una comunità di pensiero per capire la differenziazione
Creators: name: Speranca, Daniela
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2016

description: Con questo lavoro vorrei raccogliere le concezioni che hanno i bambini in merito alla differenziazione per poi creare una comunità di pensiero grazie alla quale sarà possibile realizzare un contesto adatto alla riflessione e al confronto di pensieri fra pari. Partendo dalle diverse concezioni ed emozioni che provano i bambini verso le situazioni quotidiane previste in un contesto scolastico, come ad esempio svolgere lavori differenziati, vorrei arrivare attraverso questionari e discussioni orali a capire come costruiscono e come si evolve il senso che attribuiscono i bambini alla differenziazione durante un determinato periodo di tempo. Mi interrogherò dunque per sapere quali sono le idee che un bambino associa alla differenziazione e qual è il senso che vi costruisce attorno. Attraverso questo progetto mi piacerebbe far crescere i bambini e far sviluppare nuove idee sulle differenze dando loro la possibilità di essere ascoltati prendendo in considerazione i loro pensieri. Per questo motivo ritengo di fondamentale importanza creare una comunità di pensiero, dove sarà importante accogliere e valorizzare tutte le idee degli allievi, poiché esse saranno utili per portare avanti un percorso di classe.
