description: As natural language interfaces enable users to express increasingly complex natural language queries, there is a parallel explosion of user review content that can allow users to better find items such as restaurants, books, or movies that match these expressive queries. While Neural Information Retrieval (IR) methods have provided state-of-the-art results for matching queries to documents, they have not been extended to the task of Reviewed-Item Retrieval (RIR), where query-review scores must be aggregated (or fused) into item-level scores for ranking. In the absence of labeled RIR datasets, we extend Neural IR methodology to RIR by leveraging self-supervised methods for contrastive learning of BERT embeddings for both queries and reviews. Specifically, contrastive learning requires a choice of positive and negative samples, where the unique two-level structure of our item-review data combined with meta-data affords us a rich structure for the selection of these samples. For contrastive learning in a Late Fusion scenario, we investigate the use of positive review samples from the same item and/or with the same rating, selection of hard positive samples by choosing the least similar reviews from the same anchor item, and selection of hard negative samples by choosing the most similar reviews from different items. We also explore anchor sub-sampling and augmenting with meta-data. For a more end-to-end Early Fusion approach, we introduce contrastive item embedding learning to fuse reviews into single item embeddings. Experimental results show that Late Fusion contrastive learning for Neural RIR outperforms all other contrastive IR configurations, Neural IR, and sparse retrieval baselines, thus demonstrating the power of exploiting the two-level structure in Neural RIR approaches as well as the importance of preserving the nuance of individual review content via Late Fusion methods.

description: A wheat supply model based on regional planted and harvested acreage equations represents Part I of a two part wheat econometric framework being developed to measure the factors affecting wheat production and price (demand) levels. The major characteristics of several types of wheat acreage adjustment programs in recent years have been quantified into two broad acreage policy measures - an “effective support rate", and an "effective voluntary diversion rate”. These variables along with several other economic and weather condition variables have been used to develop planted and harvested acreage equations based on the 1950 to 1970 period. The policy variables differ somewhat with respect to their impact on wheat acres planted among the major wheat growing areas, but are generally important factors affecting planted and harvested acres. Wheat market price expectations represented by the U.S. prices received by farmers the previous year also are important factors affecting wheat acres.

description: Motifs, which have been established as building blocks for network structure, move beyond pair-wise connections to capture longer-range correlations in connections and activity. In spite of this, there are few generative graph models that consider higher-order network structures and even fewer that focus on using motifs in models of dynamic graphs. Most existing generative models for temporal graphs strictly grow the networks via edge addition, and the models are evaluated using static graph structure metrics -- which do not adequately capture the temporal behavior of the network. To address these issues, in this work we propose DYnamic MOtif-NoDes (DYMOND) -- a generative model that considers (i) the dynamic changes in overall graph structure using temporal motif activity and (ii) the roles nodes play in motifs (e.g., one node plays the hub role in a wedge, while the remaining two act as spokes). We compare DYMOND to three dynamic graph generative model baselines on real-world networks and show that DYMOND performs better at generating graph structure and node behavior similar to the observed network. We also propose a new methodology to adapt graph structure metrics to better evaluate the temporal aspect of the network. These metrics take into account the changes in overall graph structure and the individual nodes' behavior over time.

Antineutrino Science in KamLAND

description: The primary goal of KamLAND is a search for the oscillation of $\barν_{\rm e}$$'$s emitted from distant power reactors. The long baseline, typically 180 km, enables KamLAND to address the oscillation solution of the solar neutrino problem with $\barν_{\rm e}$ under laboratory conditions. KamLAND found fewer reactor $\barν_{\rm e}$ events than expected from standard assumptions about $\barν_{\rm e}$$'$s propagation at more than 9 σ confidence level (C.L.). The observed energy spectrum disagrees with the expected spectral shape at more than 5 σ C.L., and prefers the distortion from neutrino oscillation effects. A three-flavor oscillation analysis of the data from KamLAND and KamLAND + solar neutrino experiments with CPT invariance, yields $Δ{\rm m}^{2}_{21} = [{7.54}^{+0.19}_{0.18},\ {7.53}^{+0.19}_{0.18}]$ $\times {10}^{-5} {\rm eV}^{2}$, $\tan^{2} θ_{12} = [{0.481}^{+0.092}_{-0.080},\ {0.437}^{+0.029}_{-0.026}]$, and ${\sin}^{2} θ_{13} = [{0.010}^{+0.033}_{-0.034},{0.023}^{+0.015}_{-0.015}]$. All solutions to the solar neutrino problem except for the large mixing angle (LMA) region are excluded. KamLAND also demonstrated almost two cycles of the periodic feature expected from neutrino oscillation effects. KamLAND performed the first experimental study of antineutrinos from the Earth$'$s interior so-called geoneutrinos (geo $\barν_{\rm e}$$'$s), and succeeded in detecting geo $\barν_{\rm e}$$`$s produced by the decays of $^{238}$U and $^{232}$Th within the Earth. Assuming a chondritic Th/U mass ratio, we obtain ${116}^{+28}_{-27}$ $\barν_{\rm e}$ events from $^{238}$U and $^{232}$Th, corresponding a geo $\barν_{\rm e}$ flux of ${3.4}^{+0.8}_{-0.8} \times {10}^{6} {\rm cm}^{-2}{\rm s}^{-1}$ at the KamLAND location. We evaluate various bulk silicate Earth composition models using the observed geoneutrino rate.

description: The pygmy-dipole resonances and photon strength functions in stable and unstable Ni and Sn isotopes are calculated within the microscopic self-consistent version of the extended theory of finite fermi systems which includes the QRPA and phonon coupling effects and uses the known Skyrme forces SLy4. The pygmy dipole resonance in $^{72}Ni$ is predicted with the mean energy of 12.4 MeV and the energy-weighted sum rule exhausting 25.6\% of the total strength. The microscopically obtained photon E1 strength functions are used to calculate nuclear reaction properties, i.e the radiative neutron capture cross section, gamma-ray spectra, and average radiative widths. Our main conclusion is that in all these quantities it is necessary to take the phonon coupling effects into account.

description: Todays world is a world of Internet, almost all work can be done with the help of it, from simple mobile phone recharge to biggest business deals can be done with the help of this technology. People spent their most of the times on surfing on the Web it becomes a new source of entertainment, education, communication, shopping etc. Users not only use these websites but also give their feedback and suggestions that will be useful for other users. In this way a large amount of reviews of users are collected on the Web that needs to be explored, analyse and organized for better decision making. Opinion Mining or Sentiment Analysis is a Natural Language Processing and Information Extraction task that identifies the users views or opinions explained in the form of positive, negative or neutral comments and quotes underlying the text. Aspect based opinion mining is one of the level of Opinion mining that determines the aspect of the given reviews and classify the review for each feature. In this paper an aspect based opinion mining system is proposed to classify the reviews as positive, negative and neutral for each feature. Negation is also handled in the proposed system. Experimental results using reviews of products show the effectiveness of the system.

description: In several sound changes, differences in production do not necessarily match those in perception. This study explores this relationship in two varieties (MZ: Mittelzone; MM: Mormanno) spoken in the Lausberg area of Southern Italy that differ in the degree to which inflectional phonetic cues are transferred from a suffix to a phonetically mid stem vowel. In MZ, the transfer can be complete (e.g. [mEs, mis]; cf. Standard Italian [meze, mezi], month/months), whereas in MM it is more marginal and with suffix preservation. Listeners of both varieties identified in a forced-choice test inflectional information from stems in MM- and MZ-produced stimuli with all suffix information removed. The results showed a perceptual advantage in morphological categorisation when listeners perceived stems of their own variety, and suggest that, compatibly with speech production, MM listeners use a phonetic mode of perception in categorising morphological information, whereas in MZ the perceptual strategy is more phonological.

description: We study how non-Markovianity of an open two-level system can be detected when continuously monitoring a part of its bosonic environment. Considering a physical scenario of an atom in a lossy cavity, we demonstrate that the properties of the time-dependent flux of the photons from the cavity allows the detection of memory effects in the atomic dynamics, without requiring state nor process tomography. This framework overlaps with effective descriptions for the memory part of the environment using pseudomode methods. Our central results show how the Markovian measurement record on the environment of an enlarged open system allows to draw conclusions on the non- Markovianity of the original system of interest.

Il s’agissait, dans ce contexte, de savoir si l’élaboration d’exposés individuels est un bon moyen d’apprentissage, et comment en tirer parti au mieux. Ce travail avait une finalité didactique et s’est intéressé aux motivations (intrinsèques et extrinsèques), aux buts d’accomplissement (maîtrise et performance) et à la perception par les élèves de l’utilité de la molécule qu’ils ont eu à étudier. Notre méthodologie s’est appuyée sur des questionnaires ayant trait à l’engagement, la motivation, les buts d’apprentissages, la perception de l’objet d’étude (notamment l’utilité ressentie de la molécule) et celle de la chimie de façon générale. Des études statistiques (moyennes, écarts types, corrélations, régressions) ont essayé de mettre en évidence l’importance du choix de ces molécules pour les apprentissages. Nous avons ainsi montré que, dans le cadre d’exposés individuels, il est favorable que les élèves aient des molécules qu’ils perçoivent comme étant assez utiles pour s’intéresser et se motiver pour la tâche. Cependant, ces molécules ne doivent pas être trop utiles afin que les élèves ne restent pas bloqués par leurs concepts quotidiens qui sont autant de barrières à la compréhension des savoirs.

description: Symmetries play a crucial role in physics and, in particular, the Noether symmetries are a useful tool both to select models motivated at a fundamental level, and to find exact solutions for specific Lagrangians. In this work, we consider the application of point symmetries in the recently proposed metric-Palatini Hybrid Gravity in order to select the $f({\cal R})$ functional form and to find analytical solutions for the field equations and for the related Wheeler-DeWitt (WDW) equation. We show that, in order to find out integrable $f({\cal R})$ models, conformal transformations in the Lagrangians are extremely useful. In this context, we explore two conformal transformations of the forms $dτ=N(a) dt$ and $dτ=N(ϕ) dt$. For the former conformal transformation, we found two cases of $f({\cal R})$ functions where the field equations admit Noether symmetries. In the second case, the Lagrangian reduces to a Brans-Dicke-like theory with a general coupling function. For each case, it is possible to transform the field equations by using normal coordinates to simplify the dynamical system and to obtain exact solutions. Furthermore, we perform quantization and derive the WDW equation for the minisuperspace model. The Lie point symmetries for the WDW equation are determined and used to find invariant solutions.

As background we use the recently constructed exact quantum solution for spherically symmetric vacuum space-time in loop quantum gravity. All calculations are finite and one recovers the usual results without the need of regularization or renormalization. This is an example of how loop quantum gravity provides a natural resolution to the infinities of quantum field theories.

description: Comme celui de toute science expérimentale, l’enseignement de la chimie est dispensé sous deux formes, travaux pratiques et cours. Il est de coutume que quelques démonstrations expérimentales relativement simples prennent part à ces derniers ; ceci s’insérant également dans le cadre de la méthode scientifique. Ce travail a donc pour but de déterminer si les démonstrations expérimentales sont reconnues par les élèves comme utiles d’un point de vue pédagogique et si elles peuvent exister en nombre idéal. Il a été réalisé dans deux gymnases différents et a eu pour cadre les cours de chimie dispensés par deux enseignants aux approches très opposées quant au nombre de démonstrations expérimentales réalisées durant leur cours. Des questionnaires ont été distribués aux élèves à plusieurs classes de niveaux et d’orientations différents de chacun des deux gymnases. Si les conclusions de notre étude révèlent que les élèves considèrent que l’idéal est d’assister à un nombre maximal de démonstrations durant les cours, il en ressort cependant qu’il existe une quantité maximale de démonstrations expérimentales à partir de laquelle elles ne représentent plus un apport pédagogique, mais une distraction. Il se dégage finalement de notre étude qu’un nombre idéal, mais difficilement chiffrable, de démonstrations expérimentales à réaliser durant les cours de chimie semble exister pour rester pédagogiquement utile. Nous pouvons en effet remarquer que ce nombre varie en fonction de la fréquence à laquelle les élèves sont habitués à en observer, de la voie et de l’option qu’ils ont choisies et du thème de la séquence enseignée, certains chapitres en nécessitant plus que d’autres.

description: In this paper we study the Birkhoff coordinates (Cartesian action angle coordinates) of the Toda lattice with periodic boundary condition in the limit where the number $N$ of the particles tends to infinity. We prove that the transformation introducing such coordinates maps analytically a complex ball of radius $R/N^α$ (in discrete Sobolev-analytic norms) into a ball of radius $R'/N^α$ (with $R,R'>0$ independent of $N$) if and only if $α\geq2$. Then we consider the problem of equipartition of energy in the spirit of Fermi-Pasta-Ulam. We deduce that corresponding to initial data of size $R/N^2$, $0

description: In this letter, we present non-degenerate ultrafast optical pump-probe studies of the carrier recombination dynamics in MoS$_{2}$ monolayers. By tuning the probe to wavelengths much longer than the exciton line, we make the probe transmission sensitive to the total population of photoexcited electrons and holes. Our measurement reveals two distinct time scales over which the photoexcited electrons and holes recombine; a fast time scale that lasts $\sim$2 ps and a slow time scale that lasts longer than $\sim$100 ps. The temperature and the pump fluence dependence of the observed carrier dynamics are consistent with defect-assisted recombination as being the dominant mechanism for electron-hole recombination in which the electrons and holes are captured by defects via Auger processes. Strong Coulomb interactions in two dimensional atomic materials, together with strong electron and hole correlations in two dimensional metal dichalcogenides, make Auger processes particularly effective for carrier capture by defects. We present a model for carrier recombination dynamics that quantitatively explains all features of our data for different temperatures and pump fluences. The theoretical estimates for the rate constants for Auger carrier capture are in good agreement with the experimentally determined values. Our results underscore the important role played by Auger processes in two dimensional atomic materials.

Constructing taohpwoh: Journeying through Pwakanyaw Christian model communities and its indigenous social paradigm
Creators: name: Cho, Violet
Publisher: name: The Australian National University
Year: 2023

description: My thesis is an historical and anthropological study of Pwakanyaw (also known as Karen) Christian communities, called taohpwoh, which emerged at the intersection of British colonisation of Burma and the collapse of the Konbaung monarchy. British colonialism and the resulting upheaval created the conditions in which Pwakanyaw Christians could construct a new form of sociality, which responded to and covertly rejected both colonial domination and the experience of marginalisation under Bamar Buddhist monarchies. The sociality that Pwakanyaw created through the taohpwoh movement involved acts of self-ascription, where membership was based on ethnicity and religion, and intentionally embraced hybridised practices, engaging with new forms of knowledge and translating them into Pwakanyaw epistemology and ontology. The taohpwoh model of community has spread across Pwakanyaw areas of Burma/Myanmar and neighbouring countries, enduring state repression, the creation of sovereign borders and decades of civil war and displacement. In this thesis, I trace how taohphoh were created, maintained and expanded through the interlinked Pwakanyaw concepts of tana, a system of belief, and tama, practice, centred on the deity, Ywa. Through the interplay of tana and tama, taohpwoh members created their own form of value and agency that allows taohpwoh to manage individual and communal challenges, protect and care for members, maintain autonomy and proliferate. The interplay between tana and tama structures relationships between human and non-human, Pwakanyaw and non-Pwakanyaw, Christian and non-Christian. This study is based on an examination of little-examined writing by Pwakanyaw Christians from the early nineteenth to mid-twentieth century, as well as ethnographic fieldwork in two taohpwoh: one in the upper Irrawaddy Delta of Myanmar and one in the Andaman Islands of India. This thesis uses translation to centre Pwakanyaw voices and concepts that have been marginalised in English and Burmese language studies, which contrasts with patterns of representation of Pwakanyaw Christians in the gaze of others as loyal subjects of British colonialism or presents their identities as inauthentic. By privileging Pwakanyaw knowledge and voices, I connect this study to the wider project of epistemic decolonisation. As a displaced Pwakanyaw person and taohpwoh member, this research is also a personal re-engagement with the taohpwoh of my ancestors, and I incorporate my own history and experience into this study, as part of an indigenous methodology.

La démarche d’investigation est justement un outil permettant d’en tenir compte. Les diverses motivations poussant à l’utilisation de cette démarche sont évoquées. La structure de la mise en place d’une démarche d’investigation est décortiquée, puis le cas particulier des ondes sonores est évoqué dans le but d’exploiter ladite structure dans un cas concret. Au préalable un regard est porté sur les conceptions des élèves à ce sujet et une liste de celles-ci est dressée. Le résultat d’une recherche d’idées de situations-problèmes est aussi exposé. Ces considérations mènent à une proposition de démarche d’investigation complète. Les obstacles à la mise en place d’une telle démarche et ses inconvénients sont ensuite évoqués, une critique intervient en fin de document.

description: The geometric arrangement of interacting (magnetic) dipoles is a question of fundamental importance in physics, chemistry and engineering. Motivated by recent progress concerning the self-assembly of magnetic structures, the equilibrium orientation of 8 interacting dipoles in a cubic cluster is investigated in detail. Instead of discrete equilibria we find a new type of ground state consisting of infinitely many orientations. This continuum of energetically degenerate states represents a yet unknown form of magnetic frustration. The corresponding dipole rotations in the flat potential valley of this Goldstone mode enable the construction of frictionless magnetic couplings. Using novel computer-assisted algebraic geometry methods, we moreover completely enumerate all equilibrium configurations. The seemingly simple cubic system allows for exactly 9536 unstable discrete equilibria falling into 183 distinct energy families.

description: Quotatives have garnered much attention in the study of discourse-pragmatic variation, due to the rapid rise of quotative 'be like', which now dominates the system of young English speakers across the globe (e.g., Buchstaller, 2015a; D’Arcy, 2017; Labov, 2018; Romaine & Lange, 1991; Tagliamonte, D'Arcy, & Rodríguez Louro, 2016). Australian English has not been absent from this discussion, having been explored in several studies (e.g. Rodríguez-Louro, 2013, 2016; Winter, 2002). This thesis presents a diachronic analysis of the quotative system in Sydney, Australia, with a particular focus on patterning across ethnicities. As a variable system, quotatives are theoretically available as an ethnolectal feature (cf. Clyne, Eisikovits, & Tollfree, 2001a). This has not been investigated extensively, but Cheshire and colleagues (2011) propose that a new form 'this is + Speaker' was created from a (language) feature pool, a result of the high linguistic diversity in London and the unguided second-language acquisition by children. Furthermore, Labov’s (1972a) foundational studies found ethnic minorities to lead language change. The data come from two corpora of sociolinguistic interviews, complied under the umbrella of the Sydney Speaks Project (Travis, 2016-2021): one legacy corpus recorded in the 1970s (Barbara M. Horvath, 1985) with Australian English (AusE) speakers of Anglo, Greek and Italian backgrounds; and a contemporary corpus currently under collection, with AusE speakers of Anglo, Italian and Chinese backgrounds. Both corpora include older and younger speakers, allowing change to be tracked in real and apparent time. These corpora provide over 1,000,000 words of speech, from 200 speakers, and approximately 5,000 quotative tokens for analysis. In the present study, I observe no qualitative difference between the four ethnic groups, despite the system becoming more varied with the addition of innovative forms ('go' in the 1970s and 'be like' today). Each group has very similar quotative systems; for example, 'be like' is non-existent in the 1970s but is the dominant form for young speakers today. 'Go' is a popular form for the young speakers in the 1970s, accounting for approximately one-fifth of all quotatives used. Nonetheless, there are some differences – young Italian Australians today appear to be leading the expansion of 'be like' from a marker of first-person internal dialogue, to encode third-person direct quotes. Distinct patterning for young Chinese Australians is found in a marginal favouring of 'be like' by men over women, in contrast to all other groups for whom 'be like' is most favoured by women. Contextualising these findings in relation to literature on ethnolectal variation, I argue that these differences are not best interpreted as “ethnolectal”, but rather, are better situated in the context of broader variation and change.

description: La maitrise de l’orthographe, de par son importance dans la vie de tous les jours, est une question inévitable dans le système scolaire. La place restreinte qui lui est dévolue dans l’enseignement du français au secondaire II devrait être compensée par son omniprésence dans la production d’écrits. Et pourtant, cela sufﬁt-il ? Pour nous par exemple, professeurs d’une discipline ayant créé son propre code – les mathématiques –, et qui dès lors n’a pour tout rapport avec la langue que le statut de branche fondamentale, quelles peuvent bien être les responsabilités qui nous échoient face aux élèves et à leur apprentissage de l’orthographe ? Le besoin se fait-il sentir et, si oui, quelle marge de manœuvre existe-t-il ? Quelles contraintes sont données ? Quelle y est la place de la nouvelle orthographe ? Ce mémoire a pour but de faire un état des lieux de l’orthographe en dehors du cours de langue. En interrogeant sur ses pratiques le corps enseignant et en recueillant les avis des élèves, un fait se dégage : nul n’est indifférent à la question de l’écriture et chacun a son avis, ses préceptes, ses recettes, ses passions, ou, à défaut, son désabusement. Au ﬁnal, les possibilités sont larges et il n’est pas incongru d’imaginer prendre en compte au gymnase l’orthographe comme critère d’évaluation, peu importe la matière enseignée. D’autant que cette simple mise en place garantit en général un soin plus grand face à la langue et n’entraine que rarement des sanctions. Il n’existe qu’une seule condition : être transparent vis-à-vis des élèves. Bien entendu, aucune attitude du professeur ne saurait faire disparaitre à jamais les lacunes orthographiques rencontrées bien trop souvent ; il s’agit cependant de garder une ligne de conduite permettant de guider les élèves vers un perfectionnement de leurs compétences linguistiques tout en conservant une cohérence explicite face à l’importance de l’orthographe dont tout le monde se réclame.

Knowledge exchange platforms, theories, progresses, and applications
Creators: name: Shi, Yingnan

description: This thesis is concerned with theories, progresses and applications that arise in online knowledge exchange platforms that are designed to support knowledge creation and sharing and to foster collaboration among users. This research topic has gained an increasing amount of attention globally as knowledge exchange platforms have proven useful in firms' open innovation and agility, helping firms and individuals spot business opportunities, and facilitating the collection, creation, evaluation, storage, accumulation and dissemination of knowledge. However, knowledge exchange platforms tend to fail, and one of the reasons is, after designing and initial development, it is also difficult to sustain users' engagement to supply their knowledge and to do so at a favourable level. In this thesis I am focusing my attention on fixing knowledge exchange problems that are commonly encountered by knowledge exchange platform practitioners and try to find theoretical and practical ways to support people's daily knowledge exchange on these platforms, which have become increasingly important and prevalent in the era of the global knowledge society. I present five specific empirical studies that contribute to a better understanding of the phenomenon. The first and second studies try to present a digital nudge design that highlights the importance of immediacy to motivate people contribute better knowledge contributions when they are involved in knowledge exchange activities. besides incentivising contributors to produce good quality knowledge pieces, most public knowledge exchange platforms also need to maximise the knowledge' publicity and ensure that those quality knowledge pieces can be distributed to as many people in need as possible. In this regard, the third study offers an exploratory case analysis of Australia's largest open knowledge exchange portal and investigates what metadata factors can motivate people to retrieve more open science knowledge and data from the open knowledge exchange portal. Some prior research agrees that using a knowledge exchange platform that adopts market-based mechanisms can increase the optimality of enhancing the effectiveness of knowledge exchange because the market mechanisms can provide opportunities for matching knowledge seekers with sources, promote efficient interactions with diverse knowledge, facilitate the use of existing knowledge, and help find solutions to unsolved problems. The fourth and the fifth studies are based on real-world use case analysis, and via observing two real knowledge markets, this thesis deepens the understanding how knowledge markets work and shows how the market-based mechanism can boost knowledge exchange.

description: L‘instanciation de l‘usage des nouvelles technologies au regard des sciences de l‘éducation n‘est efficace que si les pratiques pédagogiques s‘adaptent à la nature propre de ces nouveaux outils qui sont aussi avant tout, des médias. Ils ont la potentialité de développer des dispositifs pédagogiques où la motivation et l‘interactivité sont les moteurs de base liés à l‘information, l‘activité et la production. Cette nouvelle manière d‘enseigner peut se révéler particulièrement efficace dans les apprentissages dits, de résolution de problème, collaboratifs et par projet. Cependant, l‘investissement dans la maîtrise de ces outils est chronophage et peut être un réel frein dans leur usage par les enseignants s‘il n‘est pas accompagné dans l‘acquisition. Si des pays comme le Canada ou la Finlande sont pionniers dans le domaine et si les universités ont généralisés l‘usage de ces outils, force est de constater que l‘enseignement et notamment le secondaire, en Suisse, est en retard dans ce genre de pratique qui n‘est guère institutionnalisée. Pourtant, l‘étude de l‘outil CLAROLINE m‘a montré que ses fonctionnalités sont particulièrement adaptées à cette manière d‘apprendre orienté vers la découverte notamment, à travers les parcours pédagogiques et les travaux à remettre. Cette dernière fonctionnalité étant une possibilité de diagnostic permettant à l‘enseignant de faire le point sur sa pratique et de l‘évaluer pour la corriger. L‘expérimentation m‘a montré que l‘usage d‘une plateforme pédagogique permet de diversifier sa pratique, de gérer l‘hétérogénéité d‘une classe et de développer chez les élèves l‘habitude de chercher l‘information par eux- mêmes, de créer ensemble du savoir et renforcer ainsi, une capacité à l‘autonomie et la confiance en soi qui me semblent être l‘essentielle pour apprendre à apprendre.

New statistical results on the optical IDV data of BL Lac S5 0716+714

description: This paper reports on the statistical behaviour of the optical IntraDay Variability of BL Lac S5 0716+714. Available IntraDay Variability data in the optical is tested to see whether or not the magnitude is log-normally distributed. It was consistently found that this is not the case. This is in agreement with a previous discussion for data for the same object but in a different observational period. Simultaneously, the spectral slope of the light curves is calculated. The implications of these findings for models which discuss both the location and the source of IntraDay Variability are presented.

description: L’image est omniprésente dans nos sociétés, de plus, elle correspond, spécialement chez les jeunes, à un mode de plus en plus répandu d’acquérir de l’information au détriment de l’écrit. Avec la multiplication des beamer dans les salles, la vidéo a fait son entrée dans les classes. Mais, d’un point de vue pédagogique, son utilisation pose un certain nombre de problèmes méthodologiques. Comment faut-il les utiliser? A quelle fréquence? Et dans quel contexte? Les enseignants en histoire furent les pionniers dans l’utilisation de ce média. Ils utilisent diverses sources et proposent de nombreuses activités. Ils tirent ainsi avantage de leurs compétences dans l’analyse des documents. Les autres branches devraient profiter de leurs savoirs pour intégrer, si cela fait sens, la vidéo dans leurs cours. En économie, on a intégré la vidéo par l’intermédiaire d’extraits du Journal Télévisé. La matière s’y prête bien. En effet, elle fait souvent les titres de l’actualité, tant dans la presse écrite qu’à la télévision. Par ce biais, nous répondons à l’un des objectifs du plan d’étude cadre du programme d’économie de première année, qui veut que nos élèves soit à même d’analyser de manière critiqueet de commenter l’actualité économique. La meilleure utilisation des fiches pédagogiques ainsi que leur place par rapport à la vidéo dépendent du contenu de la vidéo et de nos objectifs. Il semblerait cependant que si l’on cherche une compréhension globale du contenu, il serait préférable de ne pas focaliser l’attention des élèves en distribuant le questionnaire avant le passage de la vidéo.
