‘Ululant more luporum’. Frank Perceptions of Other Christians’ Liturgies in Churches of the Holy Land
Creators: name: Saletti, Beatrice
Publisher: name: Sezione di Storia e Scienze dell'Antichità
Year: 2022

description: In this essay I will discuss how Frank pilgrims perceived Christian rites different from their own in the Fourteenth and Fifteenth centuries. Yet, it cannot escape us that the topic of relations between different creeds is much more complex than it seems, and is likewise highly relevant and strongly confrontational to this day, since still today many cultural stereotypes (often unknowingly) affect the interpretation of what is observed. To illustrate that point, I will borrow an example that may appear unrealistic but is instead a really occurred event: years ago, the US consul in Jerusalem received a call for help. An American woman, […] a devout Christian, called from a Palestinian village where her American church had sent her to help a parish. The poor woman was on the edge of a nervous breakdown. ‘I came to the Holy Land to help Christians!’ she shouted to the consul. As the diplomat didn’t seem to understand her distress, she continued more forcefully: ‘My church told me that I was going to work with Christians, and now instead I’m in a city of Arabs![1]’ [1] Lorieux (2001, I).

Per la biblioteca di Santa Croce: i manoscritti di autori classici ‘ad usum’ di Sebastiano Bucelli

description: This article focuses on the figure of Sebastiano Bucelli, keeper of the Santa Croce library in the first half of the 15th century; specifically the manuscripts including works by authors of the classical period used by Bucelli and further donated to the florentine convent of Santa Croce represent the objective of the study. The essay shows which classical authors and literary genres circulated and were studied in the Franciscan settings in Florence during the 1400s, in the light of the decisive turning point from the late Middle Ages to Humanism. These manuscripts were also analyzed according to a catalographic perspective in which all major codicological and paleographical elements were rendered in the form of a codex description.

description: The insertion of thermal dissipation (TD) sensors on tree stems for sap flux density (SFD) measurements can lead to SFD underestimations due to a wound formation close to the drill hole. However, the wound effect has not been assessed experimentally for this method yet. Here, we propose an empirical approach to investigate the effect of the wound healing on measured sap flux with TD probes. The approach was performed for both, diffuse-porous (Fagus sylvatica (Linnaeus)) and ring-porous (Quercus petraea (Lieblein)) species. Thermal dissipation probes were installed on different dates along the growing season to document the effects of the dynamic wound formation. The trees were cut in autumn and additional sensors were installed in the cut stems, therefore, without potential effects of wound development. A range of water pressures was applied to the stem segments and SFDs were simultaneously measured by TD sensors as well as gravimetrically in the laboratory. The formation of wounds around sensors installed in living tree stems led to underestimation of SFD by 21.4 ± 3 and 47.5 ± 3.8% in beech and oak, respectively. The differences between SFD underestimations of diffuse-porous beech and ring-porous oak were, however, not statistically significant. Sensors with 5-, 11- and 22-week-old wounds also showed no significant differences, which implies that the influence of wound formation on SFD estimates was completed within the first few weeks after perforation. These results were confirmed by time courses of SFD measurements in the field. Field SFD values decreased immediately after sensor installation and reached stable values after ~2 weeks with similar underestimations to the ones observed in the laboratory. We therefore propose a feasible approach to correct directly field observations of SFD for potential underestimations due to the wound effect.

description: Ce travail de mémoire présente une enquête sur les appuis en mathématiques donnés dans le cadre de l’enseignement post-obligatoire auprès d’enseignants et d’élèves de 1ère et 3ème année de maturité dans le canton de Vaud. Cette étude se place dans un contexte de transition vers un enseignement des sciences informatiques décidé en 2018 par la Confédération en tant que branche obligatoire d’ici 2022. Nous avions comme postulat : les mathématiques et l’informatique (sciences et non bureautique) ont beaucoup de point en commun et génèreront les mêmes difficultés chez les élèves. Sur cette base, à partir d’une bibliographie portant sur les difficultés de l’enseignement de l’informatique, les liens maths-info, les activités ludiques pour l’enseignement des maths, nous avons brièvement fait un tour d’horizon de ce qui se fait actuellement en sciences informatiques. Sur la base des réponses aux deux questionnaires soumis aux enseignants de mathématiques et aux élèves, nous avons analysé le fonctionnement des appuis en mathématiques (participation, type d’activités), l’organisation, la satisfaction des élèves et des enseignants, le suivi et les activités menées durant ces appuis. Nous les avons également interrogés sur leur perception des mathématiques, des sciences informatiques, des liens possibles entre maths et sciences informatiques et enfin d’une éventuelle transposition des pratiques et organisation des appuis en maths pour les sciences informatiques. Un volet qui nous intéressait particulièrement était le recours à des activités non conventionnelles pour l’enseignement comme des jeux, des concours. A notre grande surprise, l’organisation des appuis que nous avions imaginée et sur laquelle nous avions basé nos hypothèses n’est pas du tout celle que nous avons trouvée dans l’établissement ayant accepté de participer à cette enquête. L’enseignement des mathématiques soulève les réactions les plus diverses, la diversité des appuis et leurs suivis reflètent les difficultés des élèves et leurs besoins de ressources additionnelles. Enfin, très peu d’élèves comprennent de quoi relève les sciences informatiques et leurs objectifs, l’utilisation des jeux est absente des appuis et de l’enseignement des maths en général. Quelle conclusion tirer de tout cela ?

description: Significance: Diffuse in-vivo Flow Cytometry (DiFC) is an emerging fluorescence sensing method to non-invasively detect labeled circulating cells in-vivo. However, due to Signal-to-Noise Ratio (SNR) constraints largely attributed to background tissue autofluorescence, DiFC's measurement depth is limited. multiplies Aim: The Dual-Ratio (DR) / dual-slope is a new optical measurement method that aims to suppress noise and enhance SNR to deep tissue regions. We aim to investigate the combination of DR and Near-InfraRed (NIR) DiFC to improve circulating cells' maximum detectable depth and SNR. Approach: Phantom experiments were used to estimate the key parameters in a diffuse fluorescence excitation and emission model. This model and parameters were implemented in Monte-Carlo to simulate DR DiFC while varying noise and autofluorescence parameters to identify the advantages and limitations of the proposed technique. Results: Two key factors must be true to give DR DiFC an advantage over traditional DiFC; first, the fraction of noise that DR methods cannot cancel cannot be above the order of 10% for acceptable SNR. Second, DR DiFC has an advantage, in terms of SNR, if the distribution of tissue autofluorescence contributors is surface-weighted. Conclusions: DR cancelable noise may be designed for (e.g. through the use of source multiplexing), and indications point to the autofluorescence contributors' distribution being truly surface-weighted in-vivo. Successful and worthwhile implementation of DR DiFC depends on these considerations, but results point to DR DiFC having possible advantages over traditional DiFC.

description: Nowadays the Lyapunov exponents and Lyapunov dimension have become so widespread and common that they are often used without references to the rigorous definitions or pioneering works. It may lead to a confusion since there are at least two well-known definitions, which are used in computations: the upper bounds of the exponential growth rate of the norms of linearized system solutions (Lyapunov characteristic exponents, LCEs) and the upper bounds of the exponential growth rate of the singular values of the fundamental matrix of linearized system (Lyapunov exponents, LEs). In this work the relation between Lyapunov exponents and Lyapunov characteristic exponents is discussed. The invariance of Lyapunov exponents for regular and irregular linearizations under the change of coordinates is demonstrated.

description: Social networks have been of much interest in recent years. We here focus on a network structure derived from co-occurrences of people in traditional newspaper media. We find three clear deviations from what can be expected in a random graph. First, the average degree in the empirical network is much lower than expected, and the average weight of a link much higher than expected. Secondly, high degree nodes attract disproportionately much weight. Thirdly, relatively much of the weight seems to concentrate between high degree nodes. We believe this can be explained by the fact that most people tend to co-occur repeatedly with the same people. We create a model that replicates these observations qualitatively based on two self-reinforcing processes: (1) more frequently occurring persons are more likely to occur again; and (2) if two people co-occur frequently, they are more likely to co-occur again. This suggest that the media tends to focus on people that are already in the news, and that they reinforce existing co-occurrences.

description: In latitude-dependent energy balance models, ice-free and ice-covered conditions form physical boundaries of the system. With carbon dioxide treated as a bifurcation parameter, the resulting bifurcation diagram is nonsmooth with curves of equilibria and boundaries forming corners at points of intersection. Over long time scales, atmospheric carbon dioxide varies dynamically and the nonsmooth diagram becomes a set of quasi-equilibria. {However, when introducing carbon dynamics, care must be taken with the physical boundaries and appropriate boundary motion specified. In this article, we extend an energy balance model to include slowly varying carbon dioxide and develop a nonsmooth framework based on physically relevant boundary dynamics. Within this framework, we prove existence and uniqueness of solutions, as well as invariance of the region of phase space bounded by ice-free and ice-covered states.
HI Absorption in Low-power Radio AGNs Detected by FAST

description: We report the discovery of three HI absorbers toward low-power radio active galactic nuclei (AGNs) in a pilot HI absorption survey with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Compared to past studies, FAST observations have explored lower radio powers by $\sim$0.4 dex and detected these weakest absorbers at given redshifts. By comparing the gas properties and kinematics of sources along radio powers, we aim to explore the interplay between AGN and the surrounding interstellar medium (ISM). Compared to brighter sources at similar redshifts, our observations suggest a slightly lower detection rate of HI absorption lines ($\sim$$11.5\%$) in low-power radio AGNs with $\text{log}(P_{\text{1.4 GHz}}/\text{W Hz}^{-1})=21.8-23.7$. The low-power sources with $\text{log}(P_{\text{1.4 GHz}}/\text{W Hz}^{-1})<23$ have a lower detection rate of $\sim$$6.7\%$. Due to the incompleteness of the sample, these detection rates may represent the lower limits. The selection of more extended sources and dilution by HI emission at lower redshifts may contribute to the lower detection rate of HI absorption lines. These detected absorbers present relatively narrow line widths and comparable column densities consistent with previous observations. One absorber has a symmetric profile with a large velocity offset, while the other two show asymmetric profiles that can be decomposed into multiple components, suggesting various possibilities of gas origins and kinematics. These HI absorbers may have connections with rotating disks, gas outflows, galactic gas clouds, gas fueling of the AGN, and jet-ISM interactions, which will be further investigated with the upcoming systematic survey and spatially resolved observations.

description: In past ten years, modern societies developed enormous communication and social networks. Their classification and information retrieval processing become a formidable task for the society. Due to the rapid growth of World Wide Web, social and communication networks, new mathematical methods have been invented to characterize the properties of these networks on a more detailed and precise level. Various search engines are essentially using such methods. It is highly important to develop new tools to classify and rank enormous amount of network information in a way adapted to internal network structures and characteristics. This review describes the Google matrix analysis of directed complex networks demonstrating its efficiency on various examples including World Wide Web, Wikipedia, software architecture, world trade, social and citation networks, brain neural networks, DNA sequences and Ulam networks. The analytical and numerical matrix methods used in this analysis originate from the fields of Markov chains, quantum chaos and Random Matrix theory.

description: Owing to the data explosion and rapid development of artificial intelligence (AI), particularly deep neural networks (DNNs), the ever-increasing demand for large-scale matrix-vector multiplication has become one of the major issues in machine learning (ML). Training and evaluating such neural networks rely on heavy computational resources, resulting in significant system latency and power consumption. To overcome these issues, analog computing using optical interferometric-based linear processors have recently appeared as promising candidates in accelerating matrix-vector multiplication and lowering power consumption. On the other hand, radio frequency (RF) electromagnetic waves can also exhibit similar advantages as the optical counterpart by performing analog computation at light speed with lower power. Furthermore, RF devices have extra benefits such as lower cost, mature fabrication, and analog-digital mixed design simplicity, which has great potential in realizing affordable, scalable, low latency, low power, near-sensor radio frequency neural network (RFNN) that may greatly enrich RF signal processing capability. In this work, we propose a 2X2 reconfigurable linear RF analog processor in theory and experiment, which can be applied as a matrix multiplier in an artificial neural network (ANN). The proposed device can be utilized to realize a 2X2 simple RFNN for data classification. An 8X8 linear analog processor formed by 28 RFNN devices are also applied in a 4-layer ANN for Modified National Institute of Standards and Technology (MNIST) dataset classification.

description: Metal-organic frameworks (MOFs) are a family of materials that have high porosity and structural tunability and hold great potential in various applications, many of which requiring a proper understanding of the thermal transport properties. Molecular dynamics (MD) simulations play an important role in characterizing the thermal transport properties of various materials. However, due to the complexity of the structures, it is difficult to construct accurate empirical interatomic potentials for reliable MD simulations of MOFs. To this end, we develop a set of accurate yet highly efficient machine-learned potentials for three typical MOFs, including MOF-5, HKUST-1, and ZIF-8, using the neuroevolution potential approach as implemented in the GPUMD package, and perform extensive MD simulations to study thermal transport in the three MOFs. Although the lattice thermal conductivity (LTC) values of the three MOFs are all predicted to be smaller than 1 $\rm{W/(m\ K)}$ at room temperature, the phonon mean free paths (MFPs) are found to reach the sub-micrometer scale in the low-frequency region. As a consequence, the apparent LTC only converges to the diffusive limit for micrometer single crystals, which means that the LTC is heavily reduced in nanocrystalline MOFs. The sub-micrometer phonon MFPs are also found to be correlated with a moderate temperature dependence of LTC between those in typical crystalline and amorphous materials. Both the large phonon MFPs and the moderate temperature dependence of LTC fundamentally change our understanding of thermal transport in MOFs.

The method provides a tool to prove concentration of measure in cases where there is a Markov chain meeting certain conditions, and where the spectral gap of the chain is known. We provide several additional applications of this method. These applications include results on operator compressions using the Kac walk on $SO(n)$ and a Kac walk coupled to a thermostat, and a concentration of measure result for the length of the longest increasing subsequence of a random walk distributed under the invariant measure for the asymmetric exclusion process.

description: Several constructive homological methods based on noncommutative Gröbner bases are known to compute free resolutions of associative algebras. In particular, these methods relate the Koszul property for an associative algebra to the existence of a quadratic Gröbner basis of its ideal of relations. In this article, using a higher-dimensional rewriting theory approach, we give several improvements of these methods. We define polygraphs for associative algebras as higher-dimensional linear rewriting systems that generalise the notion of noncommutative Gröbner bases, and allow more possibilities of termination orders than those associated to monomial orders. We introduce polygraphic resolutions of associative algebras, giving a categorical description of higher-dimensional syzygies for presentations of algebras. We show how to compute polygraphic resolutions starting from a convergent presentation, and how these resolutions can be linked with the Koszul property.

description: Cone calorimeter tests were conducted to investigate the moisture transfer, burning behaviour and charring behaviour of timber material under fire heating. 100 x 100 x 50mm glue laminated larch specimens were made in cross grain and straight grain directions. The initial surface moisture contents were 15.1 wt. % (cross grain specimens) and 13.5 wt.% (straight grain specimens). Twenty specimens were heated at 50kW/m2 of irradiance. The heating duration was varied between 10 to 50 minutes. Internal temperature, surface temperature, heat release rate, and water content were measured during heating. Charred depth, coloured depth and burnt-out depth was measured after cooling. Heat release rate was measured by oxygen consumption method. Temperature was measured by an IR camera and type K thermocouples. Moisture content was measured by electrical resistance method. Charring temperature and colouring temperature were estimated by using the measured charred or coloured depth data and temperature histories. Burnt-out depth, charred depth and coloured depth was slightly larger in case of straight grain specimens than that in cross grain specimens. Heat release rates were almost constant after reaching the first peak values. Steady state values were slightly larger in straight grain specimens. Temperature creep was observed in each location at about 100℃, according to phase change of water. Maximum internal temperature of each specimen at each location increased while heating duration increased. Peak value of moisture content varied by each specimen, but the temperatures corresponding with peak moisture content were almost the same, i.e., around 100 to 120oC. Moving speed of moisture peak is about 1.30mm/min. Temperatures of charring front and colouring front were about 380 and 260℃, respectively.

description: Results are presented from a search for new physics in final states containing a photon and missing transverse momentum. The data correspond to an integrated luminosity of 19.6 inverse femtobarns collected in proton-proton collisions at sqrt(s) = 8 TeV with the CMS experiment at the CERN LHC. No deviation from the standard model predictions is observed for these final states. New, improved limits are set on dark matter production and on parameters of models with large extra dimensions. In particular, the first limits from the LHC on branon production are found and significantly extend previous limits from LEP and the Tevatron. An upper limit of 14.0 fb on the cross section is set at the 95% confidence level for events with a monophoton final state with photon transverse momentum greater than 145 GeV and missing transverse momentum greater than 140 GeV.

Un cours d’informatique est déjà présent dans les cursus du secondaire II, mais il est axé sur la bureautique et ne traite pas d’autres thèmes comme la programmation et l’algorithmique. Pour répondre à l’émergence de la numérisation, ses thèmes seront introduit dans un cours d’informatique obligatoire. Comme l’informatique et les mathématiques interagissent entre elles, il est nécessaire de savoir quels types de connaissances mathématiques sont utilisées dans le cours d’informatique.

description: We numerically investigate the phase separation dynamics of the non-reciprocal Allen-Cahn model in which two non-conserved order parameters are coupled. The system exhibits several dynamical patterns such as the randomly oscillating phase and the spiral phase as well as the homogeneously oscillating phase. Topological defects in the spirals are either bound or unbound depending on the non-reciprocality. The traveling stripe pattern is also found when the diffusion constants are highly asymmetric and the non-reciprocality is small.

description: Ce travail part du constat que, aussi bien dans les établissements scolaires que dans les universités, les langues anciennes ne sont pas considérées ni étudiées comme de véritables langues. La désignation même de « langues mortes » illustre très bien la manière dont le grec et le latin sont perçus. Le fait que les langues anciennes appartiennent au passé les sépare inévitablement d’autres langues, les langues « vivantes » et utiles à la communication et aux interactions quotidiennes. Très souvent, les programmes scolaires et les plans d’études ne font que renforcer cette perception, en insistant surtout sur le côté éminemment littéraire de ces branches. L’étude systématique (et souvent mnémonique) de la grammaire, de la syntaxe et du vocabulaire est présentée comme le seul instrument qui permette d’accéder aux sources grecques et latines et d’en dégager le sens. Sans vouloir nier l’importance de l’étude théorique de la grammaire et du vocabulaire pour l’apprentissage du grec et du latin, nous voulons ici illustrer d’autres approches possibles de ces langues et cultures. Dans la conviction que le grec, tout en n’étant plus « vivant », doit être considéré comme une langue à part entière, nous tâcherons d’appliquer à cette branche des démarches qui ne sont souvent destinées qu’à l’enseignement des langues modernes. Plus précisément, nous nous proposons de mettre en place une activité de compréhension orale portant sur la lecture de textes d’auteurs en grec ancien. Notre objectif est de montrer que, comme pour toute autre langue, l’apprentissage du grec ancien ne doit pas systématiquement passer par l’écrit. Notre hypothèse est qu’une approche moins intellectualisée des langues anciennes pourrait non seulement accroître la motivation des élèves, mais aussi les encourager à mobiliser toute une série de compétences qu’ils réservent normalement à d’autres branches.

description: We survey coding techniques that enable reliable transmission at rates that approach the capacity of an arbitrary discrete memoryless channel. In particular, we take the point of view of modern coding theory and discuss how recent advances in coding for symmetric channels help provide more efficient solutions for the asymmetric case. We consider, in more detail, three basic coding paradigms. The first one is Gallager's scheme that consists of concatenating a linear code with a non-linear mapping so that the input distribution can be appropriately shaped. We explicitly show that both polar codes and spatially coupled codes can be employed in this scenario. Furthermore, we derive a scaling law between the gap to capacity, the cardinality of the input and output alphabets, and the required size of the mapper. The second one is an integrated scheme in which the code is used both for source coding, in order to create codewords distributed according to the capacity-achieving input distribution, and for channel coding, in order to provide error protection. Such a technique has been recently introduced by Honda and Yamamoto in the context of polar codes, and we show how to apply it also to the design of sparse graph codes. The third paradigm is based on an idea of Böcherer and Mathar, and separates the two tasks of source coding and channel coding by a chaining construction that binds together several codewords. We present conditions for the source code and the channel code, and we describe how to combine any source code with any channel code that fulfill those conditions, in order to provide capacity-achieving schemes for asymmetric channels. In particular, we show that polar codes, spatially coupled codes, and homophonic codes are suitable as basic building blocks of the proposed coding strategy.

description: The Bakamjian-Thomas relativistic quark model for hadron current matrix elements, while non-covariant at finite mass, is successful in the heavy quark limit : form factors are covariant and satisfy Isgur-Wise scaling and Bjorken-Uraltsev sum rules. Motivated by the so-called "1/2 vs. 3/2 puzzle" in B decays to positive parity D**, we examine the implications of the model at finite mass. In the elastic case 1/2^- -> 1/2^-, the HQET constraints for the O(1/m_Q) corrections are analytically fulfilled. A number of satisfying regularities is also found for inelastic transitions. We compute the form factors using the wave functions given by the Godfrey-Isgur potential. For 1/2^- \to 3/2^+ the departures from the heavy quark limit are small, but we find a strong enhancement in 1/2^- -> 1/2^+ (for 0^- -> 0^+). This enhancement is linked to a serious difficulty of the model at finite mass for the inelastic transitions, namely a violation of the HQET constraints at zero recoil formulated by Leibovich et al. These are nevertheless satisfied in the non-relativistic limit for the light quark. We conclude that these HQET rigorous constraints are crucial in the construction of a sensible relativistic quark model of inelastic form factors.

Homogeneity of cohomology classes associated with Koszul matrix factorizations

description: In this work we prove the so called dimension property for the cohomological field theory associated with a homogeneous polynomial W with an isolated singularity, in the algebraic framework of arXiv:1105.2903. This amounts to showing that some cohomology classes on the Deligne-Mumford moduli spaces of stable curves, constructed using Fourier-Mukai type functors associated with matrix factorizations, live in prescribed dimension. The proof is based on a homogeneity result established in arXiv:math/0011032 for certain characteristic classes of Koszul matrix factorizations of 0. To reduce to this result we use the theory of Fourier-Mukai type functors involving matrix factorizations and the natural rational lattices in the relevant Hochschild homology spaces, as well as a version of Hodge-Riemann bilinear relations for Hochschild homology of matrix factorizations. Our approach also gives a proof of the dimension property for the cohomological field theories associated with some quasihomogeneous polynomials with an isolated singularity.

description: A broad class of models that routinely appear in several fields can be expressed as partially or fully discretized Gaussian linear regressions. Besides including classical Gaussian response settings, this class also encompasses probit, multinomial probit and tobit regression, among others, thereby yielding one of the most widely-implemented families of models in routine applications. The relevance of such representations has stimulated decades of research in the Bayesian field, mostly motivated by the fact that, unlike for Gaussian linear regression, the posterior distribution induced by such models does not seem to belong to a known class, under the commonly assumed Gaussian priors for the coefficients. This has motivated several solutions for posterior inference relying either on sampling-based strategies or on deterministic approximations that, however, still experience computational and accuracy issues, especially in high dimensions. The scope of this article is to review, unify and extend recent advances in Bayesian inference and computation for this core class of models. To address such a goal, we prove that the likelihoods induced by these formulations share a common analytical structure implying conjugacy with a broad class of distributions, namely the unified skew-normal (SUN), that generalize Gaussians to include skewness. This result unifies and extends recent conjugacy properties for specific models within the class analyzed, and opens new avenues for improved posterior inference, under a broader class of formulations and priors, via novel closed-form expressions, iid samplers from the exact SUN posteriors, and more accurate and scalable approximations from variational Bayes and expectation-propagation. Such advantages are illustrated in simulations and are expected to facilitate the routine-use of these core Bayesian models, while providing novel frameworks for studying theoretical properties and developing future extensions.

description: We examine a single-file chain of ammonia molecules in a carbon nanotube. To this end, we use i) molecular dynamics simulations (combined with the charges for ammonia nitrogen and hydrogen obtained from quantum chemistry) and ii) lattice-model calculations [M.~Druchok {\it et al.}, J. Chem. Phys. {\bf 158}, 104304 (2023)]. Our findings demonstrate the occurrence of the orientational quasiorder of the ammonia dipoles, which become parallel to the tube axis, at intermediate temperatures below $100$~K.

description: Ce travail de mémoire s’intéresse aux préoccupations des enseignants quant aux pratiques de gestion de classe. Pour commencer, celui-ci compare les enseignants débutants et les enseignants expérimentés car avec les années et l’expérience, les pratiques évoluent. Suite à cela, il s’intéresse au style pédagogique mis en place par l’enseignant, et surtout, à son effet sur la motivation et l’implication des élèves. La première hypothèse suppose que les années d’expériences dans le métier d’enseignants influencent les préoccupations que l’enseignant a au niveau du climat de classe. Elle part également du postulat qu’avec le temps, l’importance donnée au contrôle des comportements versus l’apprentissage des élèves n’est pas la même. En début de carrière, on a tendance à être préoccupé par les contenus à enseigner, au détriment du contrôle des comportements. Cependant, cet élément reprend vite le dessus, car sans un cadre favorable aux apprentissages, on ne peut pas espérer avancer dans les contenus à enseigner. Ces deux éléments sont donc très liés, et doivent être intégrés l’un dans l’autre. Les différents articles scientifiques lus et analysés tout au long de ce travail confirment effectivement cette première hypothèse. Avec le temps, les pratiques d’un enseignant expérimentés évoluent par rapport à celles effectives en début de carrière. Concernant la deuxième hypothèse, celle-ci postule que le style pédagogique mis en place par l’enseignant influence la motivation et l’engagement des élèves. Ce travail oppose deux styles extrêmes, que sont le style « contrôlant » et le style « favorisant l’autonomie ». Les résultats trouvés dans les différents articles scientifiques confirment effectivement cette seconde hypothèse. Quand l’enseignant décide de mettre un cadre trop rigide et ne permet pas aux élèves de s’exprimer, cela enfreint le développement de la motivation intrinsèque des élèves. En effet, quand on donne la possibilité à un élève de faire des choix, de s’exprimer, de faire différemment, cela peut éveiller en lui une motivation intrinsèque, qu’il possède déjà ou, simplement, qu’il est prêt à développer.
