description: We analyze the analog of the Rayleigh instability in the field of gravity for the superfluid-crystal 4He interface provided that the heavier 4He crystal phase occupies the half-space over the lighter superfluid phase. The conditions and the onset of the gravitational instability are different in kind above and below the roughening transition temperature when the crystal 4He surface is in the rough or in the smooth faceted state, respectively. In the rough state of the surface the gravitational instability is similar to the classical case of the fluid-fluid interface. In contrast, in the case of the crystal faceted surface the onset of the gravitational instability is associated with surmounting some potential barrier. The potential barrier results from nonzero magnitude of the linear facet step energy. The size and the tilting angle of the crystal facet are also important parameters for developing the instability. The initial stage of the instability can be described as a generation of crystallization waves at the superfluid-crystal interface. The experiments which may concern the gravitational instability of the superfluid-crystal 4He interface are discussed.

Searching the entirety of Kepler data : new exoplanets and occurrence rate estimates
Creators: name: Kunimoto, Michelle
Publisher: name: University of British Columbia

description: First, I present the results of an independent search of all ~200,000 stars observed over the four-year Kepler mission for multiplanet systems, using a three-transit minimum detection criteria to search orbital periods up to hundreds of days. My search returned 17 planet candidates in addition to thousands of known Kepler Objects of Interest (KOIs), with a 98.8% recovery rate of already confirmed planets. I highlight the discovery of one candidate, KIC-7340288 b, that is both rocky (radius < 1.6 R⊕) and in the habitable zone (insolation between 0.25 and 2.2 times the Earth's insolation). Another candidate is an addition to the already known KOI-4509 system. I also present adaptive optics imaging follow-up for six of my new candidates, two of which reveal a line-of-sight stellar companion within 4". Using my planet catalogue, I then present exoplanet occurrence rates estimated with approximate Bayesian computation for planets with radii between 0.5 and 16 R⊕ and orbital periods between 0.78 and 400 days, orbiting FGK dwarf stars. I characterize the efficiency of planet recovery by both my search and vetting pipelines using injection/recovery tests, and account for both planet radius uncertainty and the estimated false positive rate due to transit-like noise signals in the data, unlike the majority of previous works. By analyzing my FGK occurrence rates as well as those computed after separating F-, G-, and K-type stars, I explore dependencies on stellar effective temperature, planet radius, and orbital period. I reveal new characteristics of the photoevaporation-driven "radius gap" between ~1.5 and 2 R⊕, indicating that the significant bimodal distribution previously revealed for P < 100 days only exists over a much narrower range of orbital periods, above which sub-Neptunes dominate and below which super-Earths dominate. Finally, I provide several estimates of the "eta-Earth" value --- the frequency of potentially habitable, rocky planets orbiting Sun-like stars. For planets with sizes 0.75 - 1.5 R⊕ orbiting in a conservatively defined habitable zone (0.99 - 1.70 AU) around G-type stars, my calculations place an upper limit (84.1th percentile) of < 0.18 planets per star.

description: We investigate the problem of recovering the initial displacement f for a solution u of a linear, isotropic, non-homogeneous elastic wave equation, given measurements of u on [0,T] x \partial Ω, where Ω\subset\R^3 is some bounded domain containing the support of f. For the acoustic wave equation, this problem is known as thermoacoustic tomography (TAT), and has been well-studied; for the elastic wave equation, the situation is somewhat more subtle, and we give sufficient conditions on the Lamé parameters to ensure that recovery is possible.

Penumbral fine structure and driving mechanisms of large-scale flows in simulated sunspots

Publisher: name: arXiv
Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We analyze in detail the penumbral structure found in a recent radiative MHD simulation. Near tau=1, the simulation produces penumbral fine structure consistent with the observationally inferred interlocking comb structure. Fast outflows exceeding 8 km/s are present along almost horizontal stretches of the magnetic field; in the outer half of the penumbra, we see opposite polarity flux indicating flux returning beneath the surface. The bulk of the penumbral brightness is maintained by small-scale motions turning over on scales shorter than the length of a typical penumbral filament. The resulting vertical rms velocity at tau=1 is about half of that found in the quiet Sun. Radial outflows in the sunspot penumbra have two components. In the uppermost few 100 km, fast outflows are driven primarily through the horizontal component of the Lorentz force, which is confined to narrow boundary layers beneath tau=1, while the contribution from horizontal pressure gradients is reduced in comparison to granulation as a consequence of anisotropy. The resulting Evershed flow reaches its peak velocity near tau=1 and falls off rapidly with height. Outflows present in deeper layers result primarily from a preferred ring-like alignment of convection cells surrounding the sunspot. These flows reach amplitudes of about 50% of the convective rms velocity rather independent of depth. A preference for the outflow results from a combination of Lorentz force and pressure driving. While the Evershed flow dominates by velocity amplitude, most of the mass flux is present in deeper layers and likely related to a large-scale moat flow.

description: In this paper, we explore the relations between different kinds of Strichartz estimates and give new estimates in Euclidean space $\mathbb{R}^n$. In particular, we prove the generalized and weighted Strichartz estimates for a large class of dispersive operators including the Schrödinger and wave equation. As a sample application of these new estimates, we are able to prove the Strauss conjecture with low regularity for dimension 2 and 3.

description: Continuing work initiated in earlier publications [Yamada, Asada, Phys. Rev. D 82, 104019 (2010), 83, 024040 (2011)], we investigate the post-Newtonian effects on Lagrange's equilateral triangular solution for the three-body problem. For three finite masses, it is found that the equilateral triangular configuration satisfies the post-Newtonian equation of motion in general relativity, if and only if all three masses are equal. When a test mass is included, the equilateral configuration is possible for two cases: (1) one mass is finite and the other two are zero, or (2) two of the masses are finite and equal, and the third one is zero, namely a symmetric binary with a test mass. The angular velocity of the post-Newtonian equilateral triangular configuration is always smaller than the Newtonian one, provided that the masses and the side length are the same.

description: We analyze the performance of quantum ratchets by considering the dynamics of an initially localized wave packet loaded into a flashing periodic potential. The directed center-of-mass motion can be initiated by the uniform modulation of the potential height, provided that the modulation protocol breaks all relevant time- and spatial reflection symmetries. A poor performance of quantum ratchet transport is characterized by a slow net motion and a fast diffusive spreading of the wave packet, while the desirable optimal performance is the contrary. By invoking a quantum analog of the classical Péclet number, namely the quotient of the group velocity and the dispersion of the propagating wave packet, we calibrate the transport properties of flashing quantum ratchets and discuss the mechanisms that yield low-dispersive directed transport.

description: We investigate isometric immersions of disks with constant negative curvature into $\mathbb{R}^3$, and the minimizers for the bending energy, i.e. the $L^2$ norm of the principal curvatures over the class of $W^{2,2}$ isometric immersions. We show the existence of smooth immersions of arbitrarily large geodesic balls in $\mathbb{H}^2$ into $\mathbb{R}^3$. In elucidating the connection between these immersions and the non-existence/singularity results of Hilbert and Amsler, we obtain a lower bound for the $L^\infty$ norm of the principal curvatures for such smooth isometric immersions. We also construct piecewise smooth isometric immersions that have a periodic profile, are globally $W^{2,2}$, and have a lower bending energy than their smooth counterparts. The number of periods in these configurations is set by the condition that the principal curvatures of the surface remain finite and grows approximately exponentially with the radius of the disc. We discuss the implications of our results on recent experiments on the mechanics of non-Euclidean plates.

description: We use deep wide-field photometry from the Large Binocular Camera to study the stellar and structural properties of the recently discovered Andromeda X and Andromeda XVII (And X and And XVII) dwarf galaxies. Using the mean apparent magnitude of the horizontal branch (HB), we derive distances of 621 +- 20 kpc to And X and 734+- 23 kpc to And XVII, closer by >60 kpc than the previous estimates which were based on red giant branch (RGB) observations. Thus our results warrant against the use of the RGB tip method for determining distances to systems with sparsely populated RGBs, and show how crucial HB observations are in obtaining accurate distances in systems such as these. We find that And X is a relatively faint (MV = -7.36), highly elongated (e = 0.48) system at a distance of 174 +- 62 kpc from Andromeda. And XVII is brighter (MV = -8.61) with an M31-centric distance of 73 kpc which makes it one of the closest satellites to Andromeda. Both galaxies are metal-poor: we derive =-2.2 for And X, while And XVII shows = -2.0, consistent with the relation of higher luminosity dwarfs being more metal- rich. Additionally, both galaxies show considerable intrinsic spreads in metallicity (0.2 and 0.3 dex for And X and And XVII respectively), consistent with multiple stellar populations.

description: This research article describes the effects of a laser ablation on graphite block surface, where a Nd:YAG nanosecond-pulse laser beam was applied. Different laser energies and irradiation times as well as an argon atmosphere were used for the experiments. Surfaces of both pristine graphite and bromine intercalated graphite were targeted in dry condition. Moreover a thin layer of water or toluene were used as liquid medium for the ablations. Morphology changes on a dry graphite surface after ablation revealed traces of shock waves, which expanded across the surrounding areas. According to the energy distribution, different zones in the laser ablation areas and the surroundings were detected. In the center (zone 1), molten carbon was evidenced by a typical wave-like liquid pattern. This is especially due the high temperature and high pressure created by the laser pulses. Outside the reaction center, typical volcano-like micro-structures resulting from seething carbons were observed. The irradiation on bromine intercalated graphite has led additionally to graphite exfoliation as well as to the formation of traces of liquid (micro-droplets) carbon. By using toluene as liquid medium for ablation, graphite exfoliation was detected in zone 3. Thereafter we can conclude, that, under the extremely high temperature and high pressure achieved by nanosecond-pulsed laser, toluene was able to locally intercalate into graphite layers and then flash off after pressure was gone.

La finalità di questo progetto è la visualizzazione per mezzo di un illuminatore ad hoc e di una camera iperspettrale di cellule cancerogene, impiegando il fenomeno della fluorescenza. L’idea di produrre un illuminatore capace di utilizzare questo fenomeno nasce dalla necessità di sostituire un sistema già esistente ma con problemi a soddisfare i livelli di illuminazioni minimi per captare questo fenomeno. Un’ avveduto studio dell’arte e dei sistemi presenti sul mercato ha permesso di estrarre diverse soluzioni applicabili. Lo sviluppo del sistema prevede una parte Hardware direttamente connessa alla rete elettrica con driver e alimentatori per l’illuminatore a LED (UV e white) comandati a sestine, il tutto viene interfacciato per mezzo di un microcontrollore con un firmware per gestire un protocollo di comunicazione utente-sistema facilitato da un’interfaccia. Lo sviluppo della parte di illuminazione invece prevede la ricerca di un diffusore in modo da rendere la luce sulla superficie irradiata più uniforme possibile. Una fase finale di test elettrici e ottici hanno confermato o confutato le varianti proposte in una fase di studio degli elementi utilizzabili. Il prototipo finale è funzionante ed applicabile al gruppo microscopio camera per mezzo di un sistema di housing progettato in modo da sostenere, collimare la radiazione luminosa e dissipare il calore generato dai LED. Questo progetto inoltre verrà integrato nel progetto “FLUO” (Quantitative fluorescence for improved surgical option in the treatment of glioblastoma) sviluppato nell’Istituto sistemi e elettronica applicata (ISEA).

Creators: name: Tarnai, Markus

description: Mitoxantron ist ein potentes Zytostatikum mit erheblichen Nebenwirkungen. Auf der Suche nach Verbindungen ohne Kardiotoxizität wurde 1994 der Wirkstoff Pixantron synthetisiert und 2012 zugelassen. Strukturell wurde ein bioisosterer Austausch des π-Elektronenmangel-Aromaten vorgenommen. Aufgrund dieser Beobachtung wurde am Department für pharmazeutische Chemie der Universität Wien ein Forschungsprojekt gestartet, welches die weitere Strukturoptimierung dieser Leitstruktur im Fokus hatte. Durch weitere bioisostere Modifikationen und Derivatisierung mit diversen funktionellen Seitenketten entstand die Verbindung Dimethylaminoethyl- Isoellipticinchinon als zytotoxisch wirkstarkes Analogon des Naturstoffs Ellipticin. Der durch Benzoanellierung entstandene Pentazyklus entspricht dem Naturstoff Calothrixin. Diese Ringerweiterung zeigte generell eine negative Auswirkung auf die zytotoxische Potenz. Der natürliche Wirkstoff Calothrixin A zeichnet sich durch eine Oxidation des Stickstoffes im Ring D aus. Diese Modifikation wurde ebenfalls auf den Tetrazyklus Ellipticinchinon angewandt. Bei beiden Grundkörpersystemen führte dies zu einer erheblichen Wirkungssteigerung. Als wirkstärkste Seitenketteneinheit erwies sich die basische Struktur Dimethylaminoethyl. Im Zuge der vorliegenden Arbeit konnte gezeigt werden, dass wasserstoffbrückenbildende oder alkylierende Funktionen keinen zusätzlichen Nutzen gegenüber basisch substituierten Seitenketten bringen. Hinsichtlich der Linkerlänge wurde ersichtlich, dass eine Homologisierung auf drei Kohlenstoffatome für diese funktionelle Gruppe am effektivsten ist. Sämtliche ausstehenden Modifikationen der tetra- und pentazyklischen Grundkörperstruktur wurden durchgeführt und hinsichtlich ihrer Struktur-Wirkungsbeziehung untersucht. Parallel zur Synthesearbeit wurden die entstandenen Verbindungen mittels XTT-Zytotoxizitäts-Assay an der Kolonkarzinomzelllinie SW480 getestet. Abschließend wurden die potentesten Grundkörperstrukturen mit den stärksten Seitenketten verknüpft. Es entstanden sechs hochaktive Substanzen, die sich für weitere Untersuchungen an verschiedensten Tumorzelllinien und hinsichtlich Toxizität durchaus qualifizieren.
Y(9.46 GeV) and the gluon discovery (a critical recollection of PLUTO results)

description: The hadronic decays of Y(9.46GeV) were first studied by PLUTO experiment at DORIS e+e- storage ring (DESY). To determine the contribution of PLUTO to the discovery of the gluon, as members of the collaboration, we have reconsidered all the material produced by it in 1978 and the first half of 1979. It results clearly that the experiment demonstrated the main decay of the Y resonance to be mediated by 3 gluons hadronizing into 3 jets. Jettiness resulted evident by the with respect to the thrust axis, which was as observed by PLUTO itself at nearby continuum c.m.s. energies for 2-quark jet events. Instead, the average sphericity , more topological variables and the momentum distribution showed a net difference with the same data, results compatible with jettiness only in case of more than 2 jets. Flatness as consequence of a 3-body decay (therefore 3 jets) was indicated by the low , altogether a result independent of models. The charged multiplicity was observed to be larger than in the continuum and in case of MC 3 gluon jets fragmenting like quarks, as expected for gluon jets. In June 1979 PLUTO measured the matrix element of the 3-gluon decay to be quantitatively according QCD (even after hadronization, which does not obscure the perturbative predictions) and demonstrated the spin 1 nature of the gluon by excluding spin 0 and spin 1/2. The gluon hadronization like a quark jet, as in 3-gluon jet MC, was compatible with topological data and multiplicity; this was the first experimental study of (identified) gluon jets. The PLUTO results were confirmed both by other experiments at DORIS and later by more sophisticated detectors. At higher energies at PETRA the existence of gluons of spin 1 was confirmed by PLUTO and by 3 more experiments by measuring the gluon radiation, soft gluons by jet broadening, hard gluons by the emission of (now clearly visible) gluon jets by quarks.

description: We study non-linear contributions to the power spectrum of the curvature perturbation on super-horizon scales, produced during slow-roll inflation driven by a canonical single scalar field. We find that on large scales the linear power spectrum completely dominates and leading non-linear corrections remain totally negligible, indicating that we can safely rely on linear perturbation theory to study inflationary power spectrum. We also briefly comment on the infrared and ultraviolet behaviour of the non-linear corrections.

Message me when you land : tourism and hospitality students' social media relationships with friends, family, and devices
Creators: name: Wray, David R.
Publisher: name: University of British Columbia
Year: 2020

description: This qualitative study addressed the problem of maintaining relationships via creative and routine uses of Mobile Devices (MDs). Twelve participants were recruited from a private college in Vancouver, which specializes in tourism and hospitality education for international students. Interviews focused on their uses of MDs in creating and maintaining relationships with family and friends. The study addressed three research questions: 1) In what ways do international students utilize MDs to maintain relationships with family, friends, and the devices themselves? 1a) How do the students maintain relationships at home, school, and online, while fostering newer, more immediate relationships? 1b) How do the students maintain relationships with media and technology (M&T) devices and apps? For analysis and interpretation, the theoretical framework draws on Hinde’s (1976a, 1976b) research into relationality and on Goffman’s (1974) caution of the collusion of technology in changing relationships. Findings are organized around four themes: Shifting Time and Space Constraints, Necessity vs. Habit, Online Identity, and Influence and Marketing. Within each theme, one, two, or all three questions are explored. The participants post memes, photos, and videos to their social media but do not always keep up their relationships with family and friends directly, though they said most of their significant relationships had not faltered. Participants were hard pressed to say that their personal technology use was a bad thing, though they consistently expressed how it would get in the way of experiencing real life in the moment. The participants have their technologies on them and interact with them on a regular basis, but their views on MDs extend from necessity to habit. This research has implications for the process of intercultural relationship building among students, as it takes the pervasiveness of M&T into account. Given current conditions of life, play, study, and work, implications are placed in context of Covid-19. How this sample of international students interacts and depicts themselves online suggests the strengthening of some relationships while keeping others at a comfortable distance, but still near, nonetheless. Educators of all levels should be aware of how students create, maintain, and destroy relationships via MDs.

description: The representation of an odour space is a challenging issue for scientists and professionals working in odour-related activities. Many food and non-food sectors have created their own classification system and representations of the odorant space to manage objective communication about odours. More generally, many representations of the odorant space have been proposed. These initiatives turn the odorant space into easy-to-digest representations classifying hierarchically a restricted set of odorants in specific categories that provide a common frame of reference to professionals or sensory analysis judges. Nevertheless, the odour set is often restricted and these representations do not reflect the continuum of current odours which are not frozen in single section but on the contrary closely overlap. Thus, the related visualisations face with difficulties to represent such odour relationships. This work based on knowledge graphs from semantic web aims to propose a readable, interactive and publicly available representation of the aroma space, dedicated to olfactory and sensory practices. This representation relies on a large set of odours and takes into account overlapping categories. The knowledge-based model thus produced includes about 380 odours which are distributed in 20 main categories, which are decomposed into 117 subcategories. Seventy-seven odours and 26 categories obviously belong to multiple categories depending either on the multidimensional perception they are suggesting or on a conceptual positioning. The odour space is fully encoded into an rdf/owl Knowledge Graph, a semantic web standard language, which can be easily edited, stored, shared and requested. A hierarchical visual representation is derived to get a friendly and readable representation. The flexibility introduced by this representation enables to easily find out the relevant term(s) needed to describe an odorant perception.

description: Die Debatten über Verbraucherbilder, Konsumwandel oder Nachhaltigkeit wirken bisweilen seltsam geschichtslos, da die handelnden Akteure gegenwärtige Probleme lösen und an zukünftige Herausforderungen denken müssen. Allerdings können aus der Geschichte Einsichten für heute relevante Fragen gewonnen werden. Deshalb muss eine Verbraucherforschung, die als interdisziplinäres Projekt verstanden wird, die Geschichtswissenschaft einbeziehen. Sie eröffnet jenseits einfacher Handlungsanweisungen ein tieferes Verständnis für Entwicklungen und trägt dazu bei, alternative Blickwinkel einzunehmen und neue Pfade zu erkennen.

Structural peculiarities in Rachmaninoff’s piano concerto no. 4, op. 40
Creators: name: Korneev, Dmitri
Publisher: name: No Publisher Supplied
Year: 2024

description: Rachmaninoff (1873–1943) was one of the greatest composers and pianists of his time. He left a significant legacy in classical music, including works for piano, chamber music, symphonies, operas, and choral music. His four piano concertos are rightfully considered some of his most significant, distinguished, and popular works. Rachmaninoff’s first three concertos were written in pre-revolutionary Russia and achieved broad success. The fourth was written after his emigration to the United States following almost 10 years of silence and left both Rachmaninoff and his audiences dissatisfied. This dissertation uses Rachmaninoff’s fourth concerto as a medium to more deeply understand the crucial influence of this genius composer’s life circumstances on the continuous evolution of the concerto’s structure and the multiple attempts at its revision, which were triggered by Rachmaninoff’s painful dependence on the opinions of his audiences and critics. In various attempts to improve the reception and understanding of the piece by the public, Rachmaninoff made elaborate changes to the masterpiece’s form but succeeded only in rendering its message progressively less clear. Here, I use Hepokoski–Darcy theory and its flexible concept of the sonata form to analyze the variations in Rachmaninoff’s sonata form. I adopt a new, critical, combined version of the concerto to reinvigorate interest in this work.
description: Рахманинов (1873–1943) был одним из величайших композиторов и пианистов своего времени. Он оставил значительное наследие в области классической музыки, в том числе произведения для фортепиано, камерную музыку, симфонии, оперы и хоровую музыку. Четыре фортепианных концерта Рахманинова по праву считаются одними из самых значительных, выдающихся и популярных произведений. Первые три концерта были написаны в дореволюционной России и имели широкий успех. Четвертый был написан после эмиграции в США и почти 10 лет молчания и оставил неудовлетворенными как Рахманинова, так и его публику. В диссертации четвертый концерт Рахманинова используется для более глубокого понимания решающего влияния обстоятельств жизни этого гениального композитора на непрерывную эволюцию структуры концерта и многочисленных редактирований, вызванных болезненной зависимостью Рахманинова от мнений публики и критиков. В попытках улучшить восприятие и понимание произведения публикой Рахманинов вносил изменения в форму шедевра, но преуспел лишь в том, что его смысл становился все менее ясным. В своей работе я использую теорию Hepokoski-Darcy и их гибкую концепцию сонатной формы для анализа структуры сонатной формы Рахманинова. Также я предлагаю новую, критическую, комбинированную версию концерта, чтобы оживить интерес к этому произведению.
On the choice of parameters in Singular Spectrum Analysis and related subspace-based methods

description: In the present paper we investigate methods related to both the Singular Spectrum Analysis (SSA) and subspace-based methods in signal processing. We describe common and specific features of these methods and consider different kinds of problems solved by them such as signal reconstruction, forecasting and parameter estimation. General recommendations on the choice of parameters to obtain minimal errors are provided. We demonstrate that the optimal choice depends on the particular problem. For the basic model `signal + residual' we show that the error behavior depends on the type of residuals, deterministic or stochastic, and whether the noise is white or red. The structure of errors and the convergence rate are also discussed. The analysis is based on known theoretical results and extensive computer simulations.

description: We discuss the theory and phenomenology of pair annihilation, within an ultra-short laser pulse, to a single photon. The signature of this process is the uni-directional emission of single photons with a fixed energy. We show that the cross section is significantly larger than for two-photon pair annihilation in vacuum, with XFEL parameters admitting a much clearer signal than optical beams.

description: At present, the theory of light diffraction only has the simple wave-optical approach. In this paper, we study light diffraction with the approach of relativistic quantum theory. We find that the slit length, slit width, slit thickness and wave-length of light have affected to the diffraction intensity and form of diffraction pattern. However, the effect of slit thickness on the diffraction pattern can not be explained by wave-optical approach, and it can be explained in quantum theory. We compare the theoretical results with single and multiple slits experiment data, and find the theoretical results are accordance with the experiment data. Otherwise, we give some theory prediction. We think all the new prediction will be tested by the light diffraction experiment.

description: We suggest a braneless scenario that still hides large-volume extra dimensions. Ordinarily the strength of bulk gauge interactions would be diluted over the large internal volume, making all the four dimensional forces weak. We use the fact that if the gauge fields result from the dimensional reduction of pure higher-dimensional gravity, then the strengths of the four dimensional gauge interactions are related to the sizes of corresponding cycles averaged over the compact internal manifold. Therefore, if a gauge force is concentrated over a small cycle it will not be diluted over the entire manifold. Gravity, however, remains diluted over the large volume. Thus large-volume, large mass gap extra dimensions with small cycles can remain hidden and result in a hierarchy between gravity and the other forces. However, problematically, the cycles are required to be smaller than the higher-dimensional Planck length and this raises concern over quantum gravity corrections. We speculate on possible cures.

Un fare che sia narrazione di sé

description: La ricerca si propone di studiare se l’inserimento di una didattica narrativa, all’interno delle lezioni di Educazione alle arti plastiche rivolte agli allievi di seconda media, possa incrementare lo sviluppo di sé, per permettere all’allievo di attivarsi cognitivamente ed emotivamente nell’apprendimento di saperi ed abilità utili ad affrontare situazioni, conosciute o nuove, per crescere positivamente in quanto protagonista del proprio vissuto personale. In questo senso, l’obiettivo sarà quello di renderlo autonomo e consapevole, muovendosi parallelamente sia in ambito estetico che poietico rispetto alla realizzazione di manufatti coerenti e rappresentativi di un punto di vista personale sul mondo. Facendo riferimento a quelle che sono le teorie relative all’importanza di un fare manuale per lo sviluppo dell’individuo nella sua interezza, nel suo essere fisico oltre che pensante, nel suo esserci concreto all’interno della società, nonché all’importanza data all’espressione di sé sulla base del modello narrativo come strumento conoscitivo ed interpretativo della realtà. La didattica disciplinare si è così strutturata secondo un concatenarsi di attività che permettessero un’alta personalizzazione del prodotto atteso. Per progettare autonomamente la propria azione e realizzare consapevolmente il proprio elaborato, l’individuo deve riflettere su di sé, su ciò che gli piace e sugli apprendimenti che fino a quel momento è riuscito a stabilizzare cognitivamente. Solo interrogandosi sul cosa e sul come, l’allievo ha l’occasione di comprendere ciò che è in grado di fare e laddove invece dovrà nuovamente soffermarsi, per agire funzionalmente agli scopi che intende perseguire oggi e nel futuro. Per riflettere sul proprio percorso in modo progressivo, gli allievi della classe sperimentale hanno avuto modo di tenerne traccia all’interno di un quaderno personale, il cahier de voyage, strumento che invece la classe di controllo non ha usato. La conclusione di questa ricerca, avviata mediante un paradigma fenomenologico-ermeneutico, è che si può individuare nell’agire dei ragazzi della classe di sperimentazione, un agire più riflessivo e analitico rispetto alle richieste attese dalle consegne esplicitate. Gli allievi si sono implicati maggiormente nel risolvere autonomamente problemi e difficoltà, nonché nell’interpretare secondo uno sguardo più personale e creativo i lavori proposti. L’uso del cahier de voyage ha permesso agli allievi di tracciare più facilmente una rotta e comprenderne il senso, valorizzandoli e portandoli a sviluppare il proprio potenziale.
