Crowdsourcing Controller -- Utilizing Reliable Agents in a Multiplayer Game

description: This paper presents a new use case for continuous crowdsourcing, where multiple players collectively control a single character in a video game. Similar approaches have already been proposed, but they suffer from certain limitations: (1) they simply consider static time frames to group real-time inputs from multiple players; (2) then they aggregate inputs with simple majority vote, i.e., each player is uniformly weighted. We present a continuous crowdsourcing multiplayer game equipped with our Crowdsourcing Controller. The Crowdsourcing Controller addresses the above-mentioned limitations: (1) our Dynamic Input Frame approach groups incoming players' input in real-time by dynamically adjusting the frame length; (2) our Continuous Reliability System estimates players' skills by assigning them a reliability score, which is later used in a weighted majority vote to aggregate the final output command. We evaluated our Crowdsourcing Controller offline with simulated players and online with real players. Offline and online experiments show that both components of our Crowdsourcing Controller lead to higher game scores, i.e., longer playing time. Moreover, the Crowdsourcing Controller is able to correctly estimate and update players' reliability scores.

description: As Statistics Korea replaced the beef statistics with beef traceability data from September 2017, it is necessary to develop an economic model of Hanwoo based on the data. This study developed an advanced supply-demand model of Hanwoo by utilizing endogenous advantages of the data. The model was constructed by using a mixture of the cohort factor method and econometric method. We estimated cohort factors, such as mortality, slaughter, and sex ratio at birth, and attempted to build a stable model using the cohort factors. On the other hand, the econometric methods were used because the farm household’s intention to breed and slaughter as well as the intention of consumption are determined by various economic factors. The model developed in this study is expected to be useful as a tool to forecast the Hanwoo market and establish the preemptive supply and demand policies.

description: If you walk on sand, it supports your weight. How do the disordered forces between particles in sand organize, to keep you from sinking? This simple question is surprisingly difficult to answer experimentally: measuring forces in three dimensions, between deeply buried grains, is challenging. We describe here experiments in which we have succeeded in measuring forces inside a granular packing subject to controlled deformations. We connect the measured micro-scale forces to the macro-scale packing force response with an averaging, mean field calculation. This calculation explains how the combination of packing structure and contact deformations produce the unexpected mechanical response of the packing, and reveals a surprising microscopic particle deformation enhancement mechanism.

description: Computation in the brain involves multiple types of neurons, yet the organizing principles for how these neurons work together remain unclear. Information theory has offered explanations for how different types of neurons can optimize the encoding of different stimulus features. However, recent experiments indicate that separate neuronal types exist that encode the same stimulus features, but do so with different thresholds. Here we show that the emergence of these types of neurons can be quantitatively described by the theory of transitions between different phases of matter. The two key parameters that control the separation of neurons into subclasses are the mean and standard deviation of noise levels among neurons in the population. The mean noise level plays the role of temperature in the classic theory of phase transitions, whereas the standard deviation is equivalent to pressure, in the case of liquid-gas transitions, or to magnetic field for magnetic transitions. Our results account for properties of two recently discovered types of salamander OFF retinal ganglion cells, as well as the absence of multiple types of ON cells. We further show that, across visual stimulus contrasts, retinal circuits continued to operate near the critical point whose quantitative characteristics matched those expected near a liquid-gas critical point and described by the nearest-neighbor Ising model in three dimensions. By operating near a critical point, neural circuits can optimize the trade-off between maximizing information transmission in a given environment and quickly adapting to a new environment.

description: Hybrid approaches for automatic vowelization of Arabic texts are presented in this article. The process is made up of two modules. In the first one, a morphological analysis of the text words is performed using the open source morphological Analyzer AlKhalil Morpho Sys. Outputs for each word analyzed out of context, are its different possible vowelizations. The integration of this Analyzer in our vowelization system required the addition of a lexical database containing the most frequent words in Arabic language. Using a statistical approach based on two hidden Markov models (HMM), the second module aims to eliminate the ambiguities. Indeed, for the first HMM, the unvowelized Arabic words are the observed states and the vowelized words are the hidden states. The observed states of the second HMM are identical to those of the first, but the hidden states are the lists of possible diacritics of the word without its Arabic letters. Our system uses Viterbi algorithm to select the optimal path among the solutions proposed by Al Khalil Morpho Sys. Our approach opens an important way to improve the performance of automatic vowelization of Arabic texts for other uses in automatic natural language processing.

description: To make machine learning (ML) sustainable and apt to run on the diverse devices where relevant data is, it is essential to compress ML models as needed, while still meeting the required learning quality and time performance. However, how much and when an ML model should be compressed, and {\em where} its training should be executed, are hard decisions to make, as they depend on the model itself, the resources of the available nodes, and the data such nodes own. Existing studies focus on each of those aspects individually, however, they do not account for how such decisions can be made jointly and adapted to one another. In this work, we model the network system focusing on the training of DNNs, formalize the above multi-dimensional problem, and, given its NP-hardness, formulate an approximate dynamic programming problem that we solve through the PACT algorithmic framework. Importantly, PACT leverages a time-expanded graph representing the learning process, and a data-driven and theoretical approach for the prediction of the loss evolution to be expected as a consequence of training decisions. We prove that PACT's solutions can get as close to the optimum as desired, at the cost of an increased time complexity, and that, in any case, such complexity is polynomial. Numerical results also show that, even under the most disadvantageous settings, PACT outperforms state-of-the-art alternatives and closely matches the optimal energy cost.

description: We present a maximum-likelihood estimation algorithm for radio channel measurements exhibiting a mixture of independent Dense Multipath Components. The novelty of our approach is in the algorithms initialization using a deep learning architecture. Currently, available approaches can only deal with scenarios where a single mode is present. However, in measurements, two or more modes are often observed. This much more challenging multi-modal setting bears two important questions: How many modes are there, and how can we estimate those? To this end, we propose a Neural Net-architecture that can reliably estimate the number of modes present in the data and also provide an initial assessment of their shape. These predictions are used to initialize for gradient- and model-based optimization algorithm to further refine the estimates. We demonstrate numerically how the presented architecture performs on measurement data and analytically study its influence on the estimation of specular paths in a setting where the single-modal approach fails.

description: X-ray photoemission spectra generally exhibit satellite features in addition to the quasi-particle peaks due to many-body excitations, which have been of considerable theoretical and experimental interest. However, the satellites attributed to charge-transfer (CT) excitations in correlated materials have proved difficult to calculate from first principles. Here we report a real-time, real-space approach for such calculations based on a cumulant representation of the core-hole Green's function and time-dependent density functional theory. This approach also yields an interpretation of CT satellites in terms of a complex oscillatory, transient response to a suddenly created core hole. Illustrative results for TiO$_2$ and NiO are in good agreement with experiment.

description: The extreme growth of the World Wide Web in the last decade together with recent scandals related to theft or abusive use of personal information have left users unsatisfied withtheir digital identity providers and concerned about their online privacy. Self-SovereignIdentity (SSI) is a new identity management paradigm which gives back control over personal information to its rightful owner - the individual. However, adoption of SSI on theWeb is complicated by the high overhead costs for the service providers due to the lackinginteroperability of the various emerging SSI solutions. In this work, we propose an AccessControl System based on Self-Sovereign Identities with a semantically modelled AccessControl Logic. Our system relies on the Web Access Control authorization rules usedin the Solid project and extends them to additionally express requirements on VerifiableCredentials, i.e., digital credentials adhering to a standardized data model. Moreover,the system achieves interoperability across multiple DID Methods and types of VerifiableCredentials allowing for incremental extensibility of the supported SSI technologies bydesign. A Proof-of-Concept prototype is implemented and its performance as well as multiple system design choices are evaluated: The End-to-End latency of the authorizationprocess takes between 2-5 seconds depending on the used DID Methods and can theoretically be further optimized to 1.5-3 seconds. Evaluating the potential interoperabilityachieved by the system shows that multiple DID Methods and different types of VerifiableCredentials can be supported. Lastly, multiple approaches for modelling required Verifiable Credentials are compared and the suitability of the SHACL language for describingthe RDF graphs represented by the required Linked Data credentials is shown.

description: We describe the dynamics of magnetic skyrmions in synthetic antiferromagnets (SAF), with a finite interlayer coupling. Due to the opposite gyrovector of the skyrmions in the two SAF layers, the coupled skyrmions reach a stationary regime with a spatial separation, in a direction orthogonal to their velocity. As a consequence, and contrary to the ferromagnetic situation, a transient regime necessarily occurs, with a finite acceleration, related to an inertia, and that limits its time response. The formalism developed here, based on two coupled Thiele equations, allows a quantitative description of this phenomenon. The time constant associated to the transient regime scales inversely with the antiferromagnetic coupling constant. We also show that the coupling force reaches a maximal value at a finite skyrmion separation. This sets a maximum velocity limit, beyond which the the coupling force cannot stabilize the bound state.

description: We reexamine the characterization of incentive compatible single-parameter mechanisms introduced in Archer & Tardos(2001). We argue that the claimed uniqueness result, called `Myerson's Lemma' was not well established. We provide an elementary proof of uniqueness that unifies the presentation for two classes of allocation functions used in the literature and show that the general case is a consequence of a little known result from the theory of real functions. We also clarify that our proof of uniqueness is more elementary than the previous one. Finally, by generalizing our characterization result to more dimensions, we provide alternative proofs of revenue equivalence results for multiunit auctions and combinatorial auctions.

description: We study the stabilization and electrical manipulation of skyrmions in magnetic ultrathin films in the absence of an applied magnetic field. We show that this requires an increased magnetic anisotropy, controlled by the sample thickness, as compared to usual skyrmionic samples, so that the uniform state corresponds to the zero field ground state and the skyrmions to metastable excitations. Although skyrmion stabilization at zero field is demonstrated over a broad range of thicknesses, electrical control appeared to be more demanding to avoid skyrmion deformation. In the thinnest samples, the large magnetic anisotropy prevents skyrmion deformations and we show that they can be nucleated progressively by current pulses, which underlines that the only possible transition occurs between uniform and skyrmion states. The solitonic skyrmions in zero applied magnetic field have the same properties as compared to field stabilized ones, with a long-term stability and high mobility when excited by a spin-orbit torque.

We manipulate the parameters of the Hamiltonian of the superconducting qubit along paths in the manifold and extract $C_\mathrm{1}$ from the nonadiabitic response of the qubit. By adjusting the manifold such that a degeneracy in the Hamiltonian passes from inside to outside the manifold, we observe a topological transition $C_\mathrm{1} = 1 \rightarrow 0$. Our measurement of $C_\mathrm{1}$ is quantized to within 2 percent on either side of the transition.

description: N6-isopentenyladenosine (IPA) and its analogue N6-benzyladenosine (N6-BA) are modified nucleosides endowed with potent in vitro antitumor activity on different types of human cancers, including colorectal cancer (CRC) and glioblastoma multiforme (GBM). Although the molecules seem to exert their anti-proliferative effects partially through the inhibition of Farnesyl Diphosphate Synthase (FDPS), their precise mechanisms of action remain to be uncovered. The main aim of my PhD project was to investigate the effects of the isoprenoid derivative N6-BA, by comparing them to those of the lead compound IPA, on the modulation of cancer-related pathways. I found that both IPA and N6-BA affect CRC and GBM cell lines proliferation by modulating the expression of the F-box WD repeat domain-containing 7 (FBXW7), widely considered a tumor suppressor since its crucial role in the turnover of many proteins (i.e. c-Myc, SREBPs and Mcl1) contributing to malignant progression. In CRC, FBXW7/SREBP/FDPS axis was identified as a target of the compounds. IPA was found to induce the ubiquitination of c-Myc, inhibiting its transcriptional activity through the increase of FBXW7/c-Myc binding and N6-BA acts almost in a similar way. Moreover, IPA involvement in chemoresistance was also investigated. IPA synergized with 5-Fluorouracil in FBXW7- and TP53-wild type CRC cells and sensitized GBM cells to the toxic effect of Temozolomide. Overall, results here showed provide novel insights into the molecular mechanism of the modified adenosines and suggested the existence of an epigenetic regulation underlying their pleiotropic effects in cancer. Restoring of FBXW7 tumor-suppressor represents a valid therapeutic tool, enabling modified adenosines as optimizable compound for patient-personalized therapies in both CRC and GBM.[edited by Author]

description: Background. Astrometry at or below the micro-arcsec level with an imaging telescope assumes that the uncertainty on the location of an unresolved source can be an arbitrarily small fraction of the detector pixel, given a sufficient photon budget. Aim. This paper investigates the geometric limiting precision, in terms of CCD pixel fraction, achieved by a large set of star field images, selected among the publicly available science data of the TESS mission. Method. The statistics of the distance between selected bright stars ($G \simeq 5\,mag$), in pixel units, is evaluated, using the position estimate provided in the TESS light curve files. Results. The dispersion of coordinate differences appears to be affected by long term variation and noisy periods, at the level of $0.01$ pixel. The residuals with respect to low-pass filtered data (tracing the secular evolution), which are interpreted as the experimental astrometric noise, reach the level of a few milli-pixel or below, down to $1/5,900$ pixel. Saturated images are present, evidencing that the astrometric precision is mostly preserved across the CCD columns, whereas it features a graceful degradation in the along column direction. The cumulative performance of the image set is a few micro-pixel across columns, or a few 10 micro-pixel along columns. Conclusions. The idea of astrometric precision down to a small fraction of a CCD pixel, given sufficient signal to noise ratio, is confirmed by real data from an in-flight science instrument to the $10^{-6}$ pixel level. Implications for future high precision astrometry missions are briefly discussed.

description: In this study, we propose methods for the automatic detection of photospheric features (bright points and granules) from ultra-violet (UV) radiation, using a feature-based classifier. The methods use quiet-Sun observations at 214 nm and 525 nm images taken by Sunrise on 9 June 2009. The function of region growing and mean shift procedure are applied to segment the bright points (BPs) and granules, respectively. Zernike moments of each region are computed. The Zernike moments of BPs, granules, and other features are distinctive enough to be separated using a support vector machine (SVM) classifier. The size distribution of BPs can be fitted with a power-law slope -1.5. The peak value of granule sizes is found to be about 0.5 arcsec^2. The mean value of the filling factor of BPs is 0.01, and for granules it is 0.51. There is a critical scale for granules so that small granules with sizes smaller than 2.5 arcsec^2 cover a wide range of brightness, while the brightness of large granules approaches unity. The mean value of BP brightness fluctuations is estimated to be 1.2, while for granules it is 0.22. Mean values of the horizontal velocities of an individual BP and an individual BP within the network were found to be 1.6 km/s and 0.9 km/s, respectively. We conclude that the effect of individual BPs in releasing energy to the photosphere and maybe the upper layers is stronger than what the individual BPs release into the network.

description: We compare the morphologies of a sample of 20 LIRGs from the Great Observatories All-sky LIRG Survey (GOALS) in the FUV, B, I and H bands, using the Gini (G) and M20 parameters to quantitatively estimate the distribution and concentration of flux as a function of wavelength. HST images provide an average spatial resolution of ~80 pc. While our LIRGs can be reliably classified as mergers across the entire range of wavelengths studied here, there is a clear shift toward more negative M20 (more bulge-dominated) and a less significant decrease in G values at longer wavelengths. We find no correlation between the derived FUV G-M20 parameters and the global measures of the IR to FUV flux ratio, IRX. Given the fine resolution in our HST data, this suggests either that the UV morphology and IRX are correlated on very small scales, or that the regions emitting the bulk of the IR emission emit almost no FUV light. We use our multi-wavelength data to simulate how merging LIRGs would appear from z~0.5-3 in deep optical and near-infrared images such as the HUDF, and use these simulations to measure the G-M20 at these redshifts. Our simulations indicate a noticeable decrease in G, which flattens at z >= 2 by as much as 40%, resulting in mis-classifying our LIRGs as disk-like, even in the rest-frame FUV. The higher redshift values of M20 for the GOALS sources do not appear to change more than about 10% from the values at z~0. The change in G-M20 is caused by the surface brightness dimming of extended tidal features and asymmetries, and also the decreased spatial resolution which reduced the number of individual clumps identified. This effect, seen as early as z~0.5, could easily lead to an underestimate of the number of merging galaxies at high-redshift in the rest-frame FUV.

description: In this paper, we consider resource allocation optimization problem in cellular networks for different types of users running multiple applications simultaneously. In our proposed model, each user application is assigned a utility function that represents the application type running on the user equipment (UE). The network operators assign a subscription weight to each UE based on its subscription. Each UE assigns an application weight to each of its applications based on the instantaneous usage percentage of the application. Additionally, UEs with higher priority assign applications target rates to their applications. Our objective is to allocate the resources optimally among the UEs and their applications from a single evolved node B (eNodeB) based on a utility proportional fairness policy with priority to real-time application users. A minimum quality of service (QoS) is guaranteed to each UE application based on the UE subscription weight, the UE application weight and the UE application target rate. We propose a two-stage rate allocation algorithm to allocate the eNodeB resources among users and their applications. Finally, we present simulation results for the performance of our rate allocation algorithm.

NORTH KOREA'S NUCLEAR WEAPONS PROGRAM

description: Developing of nuclear infrastructure and producing nuclear weapons takes time, especially for developing countries like the DPRK. Therefore, we must analyze the North Koreans’ threat perceptions over the past half of the century and especially at the initial stage to understand their motivations for acquiring nuclear weapons clearly. The North Korean leadership’s political decision to develop a nuclear infrastructure and seek nuclear weapons was not made in a vacuum. Pyongyang confronts a number of external and internal security problems. During the Korean War, North Korea was subjected to nuclear threats by the US. After the War the DPRK formed security alliances with China and the Soviet Union, but the DPRK leaders were dissatisfied with their alliance partners on several occasions. Some analysts argue that inter-Korean rivalry has also motivated Pyongyang to acquire nuclear technologies. Overall, a number of factors has motivated North Korea to develop a nuclear infrastructure and seek nuclear weapons. North Korea’s opaque government and policymaking process often create difficult challenges for those seeking to understand Pyongyang’s motivations; however, a clear understanding of these motivations could be critical for diplomatic end of the North Korea’s nuclear weapons program.

description: We present results for the hadronic running of the electromagnetic coupling and the weak mixing angle from simulations of lattice QCD with $N_f=2+1$ flavours of $O(a)$-improved Wilson fermions. Using two different discretisations of the vector current, we compute the quark-connected and -disconnected contributions to the hadronic vacuum polarisation (HVP) functions $\barΠ^{γγ}$ and $\barΠ^{Zγ}$ for spacelike squared momenta $Q^2\leq 7$ $\mathrm{GeV}^2$. Our results are extrapolated to the physical point using ensembles at four lattice spacings, with pion masses ranging from 130 to 420 MeV. We observe a tension of up to 3.5 standard deviations between our lattice results for $Δα_{\rm had}^{(5)}(-Q^2)$ and estimates based on the $\textit{R}$-ratio for space-like momenta in the range $Q^2=3-7\,\rm GeV^2$. To obtain an estimate for $Δα_\mathrm{had}^{(5)}(M_Z^2)$, we employ the Euclidean split technique. The implications for comparison with global electroweak fits are assessed.

description: Vor dem Ausbruch der COVID-19 Pandemie haben Mitglieder agiler Softwareentwicklungsteams üblicherweise gemeinsam im Büro gearbeitet. Durch die rasche Verbreitung des Coronavirus wurden diese Teams weltweit ins Home Office geschickt, um die Ausbreitung des Virus einzudämmen. Verschiedene Studien weisen darauf hin, dass viele Mitglieder agiler Softwareentwicklungsteams nach dem Ende der Pandemie nicht wieder in Vollzeit in das Büro zurückkehren wollen, sondern einen hybriden Ansatz zwischen dem Büro und dem Home Office präferieren. Das Ziel dieser Abschlussarbeit ist herauszufinden, wie Mitglieder agiler Softwareentwicklungsteams sich die Zukunft ihrer Arbeit vorstellen. Dazu wurde eine quantitative Datenerhebung in Form einer webbasierten Befragung mittels eines standardisierten Fragebogens unter Mitgliedern agiler Softwareentwicklungsteams durchgeführt. Das Ergebnis ist, dass eine flexible Wahl des Arbeitsortes erwartet wird, wobei das Home Office zukünftig der präferierte Arbeitsort sein wird. Einen Einfluss durch agile Rahmenwerke und den dazugehörigen Praktiken auf die Wahl des Arbeitsortes konnte nicht festgestellt werden. Für die Zukunft wird keine signifikante Produktivitätssteigerung durch ein hybrides Arbeitsmodell erwartet.
description: Before the outbreak of the covid-19 pandemic, members of agile software development teams typically worked together in the office. Due to the rapid spread of the corona virus, these teams were sent to the home office globally to limit the spread of the virus. Various studies indicate that many members of agile software development teams do not want to return to the office full-time after the end of the pandemic but prefer a hybrid approach between the office and the home office. The aim of this thesis is to find out how members of agile software development teams envision the future of their work. For this purpose, a quantitative data collection was conducted in the form of a web-based survey using a standardized questionnaire among members of agile software development teams. The result is that a flexible choice of work location is expected, whereby the home office will be the preferred work location in the future. An influence of agile methods and the associated practices on the choice of work location could not be determined. No significant increase in productivity is expected in the future through a hybrid working model.

description: In 1994, J.Cobb described a Cantor set in $\mathbb{R}^3$ each of whose projections into 2-planes is one-dimensional. A series of works by other authors developing this field followed. We present another very simple series of Cantor sets in $\mathbb{R}^3$ all of whose projections are connected and one-dimensional. These are self-similar Cantor sets which go back to the work of Louis Antoine, and we celebrate their centenary birthday in 2020-2021.
On detailed balance in nonadiabatic dynamics: From spin spheres to equilibrium ellipsoids

description: Trajectory-based methods that propagate classical nuclei on multiple quantum electronic states are often used to simulate nonadiabatic processes in the condensed phase. A long-standing problem of these methods is their lack of detailed balance, meaning that they do not conserve the equilibrium distribution. In this article, we investigate ideas for how to restore detailed balance in mixed quantum--classical systems by tailoring the previously proposed spin-mapping approach to thermal equilibrium. We find that adapting the spin magnitude can recover the correct long-time populations but is insufficient to conserve the full equilibrium distribution. The latter can however be achieved by a more flexible mapping of the spin onto an ellipsoid, which is constructed to fulfill detailed balance for arbitrary potentials. This ellipsoid approach solves the problem of negative populations that has plagued previous mapping approaches and can therefore be applied also to strongly asymmetric and anharmonic systems. Because it conserves the thermal distribution, the method can also exploit efficient sampling schemes used in standard molecular dynamics, which drastically reduces the number of trajectories needed for convergence. The dynamics does however still have mean-field character, as is observed most clearly by evaluating reaction rates in the golden-rule limit. This implies that although the ellipsoid mapping provides a rigorous framework, further work is required to find an accurate classical-trajectory approximation that captures more properties of the true quantum dynamics.

description: Excess individual creativity can be detrimental to society because creators invest in unproven ideas at the expense of propagating proven ones. Moreover, a proportion of individuals can benefit from creativity without being creative themselves by copying creators. We hypothesized that (1) societies increase their rate of cultural evolution by tempering the novelty-generating effects of creativity with the novelty-preserving effects of imitation, and (2) this is carried out by selectively rewarding and punishing creativity according to the value of the individuals' creative outputs. We tested this using an agent-based model of cultural evolution in which each agent self-regulated its invention-to-imitation ratio as a function of the fitness of its cultural outputs. In self-regulating societies, agents segregated into creators and imitators. The mean fitness of cultural outputs was higher than in non-self-regulating societies, and changes in diversity were rapider and more pronounced. We discuss limitations and possible social implications of our findings.

description: The life of Raissa Bloch-Gorlin (1898-1943), historian and poet, is not well known. We know that she first studied at the Department of history at Petrograd University, particularly with Professor Olga Dobiach-Rojdestvensky. In 1922 she had to move to Berlin and carried on her studies of medieval manuscripts and medieval Europe history. Graduated in 1928 from Berlin University, she became an assistant to Professor Albert Brackmann at the MGH. Forced to leave Germany in 1933, she settled in Paris and worked with Professor Ferdinand Lot for the «Comité Du Cange». During the WWII, she and her husband, the poet and slavist Michel Gorlin (1909-1942) were successively arrested and both perished in concentration camps. The confrontation of several French, German, American, Swiss and Russian Archival Collections allows going into details regarding her original course. It shows the tragic character of her fate and allows describing her role in the scientific transfers between the Russian, German and French medievalists during the first half of the twentieth century.

description: Η αλματώδης ανάπτυξη των επιστημών και της τεχνολογίας που έχει σημειωθεί τον εικοστό αιώνα έχει συμβάλει στη διαμόρφωση νέων κοινωνικών, πολιτικών και οικονομικών συνθηκών στο παγκόσμιο σκηνικό. Οι νέες αυτές συνθήκες φέρνουν νέες τάσεις και νέα φιλοσοφία σε πολλά πεδία της εκπαίδευσης. Όσον αφορά στη διδασκαλία των Φυσικών Επιστημών τα τελευταία χρόνια παρουσιάστηκαν νέα εκπαιδευτικά προγράμματα με γενικό τίτλο Επιστημονικός και Τεχνολογικός Αλφαβητισμός’ (Scientific and Technological Literacy). Κύριος σκοπός των προγραμμάτων αυτών είναι όλοι οι μαθητές και όλες οι μαθήτριες να αποκτήσουν βασικές γνώσεις από τις επιστήμες και την τεχνολογία που θα τους χρειαστούν στην κοινωνική και επαγγελματική τους ζωή (Osborne 2000, Καρύδας και Κουμαράς, 2002). Στο πλαίσιο αυτό κινείται και η παρούσα εργασία η οποία έχει σκοπό μέσα από το σχεδιασμό διδακτικού υλικού να συνδέσει την έννοια της ενέργειας με θέματα περιβάλλοντος. Η έννοια της ενέργειας επιλέχθηκε γιατί είναι θεμελιώδης στις Φυσικές Επιστήμες ενώ η Ιστορία έχει δείξει και τον σπουδαίο ρόλο της στην εξέλιξη του ανθρώπινου πολιτισμού. Χρησιμοποιείται συνεχώς τόσο στην επιστημονική ορολογία όσο και σε ευρύτερα κοινωνικά θέματα όπως οι συμβατικές και οι ανανεώσιμες πηγές ενέργειας, η εξοικονόμηση ενέργειας, οι επιπτώσεις από την κακή διαχείριση της ενέργειας κλπ. Το διδακτικό υλικό έχει σχεδιαστεί με θεωρητικό πλαίσιο τον κοινωνικό εποικοδομητισμό και απευθύνεται σε μαθητές και μαθήτριες της τρίτης τάξης του Γυμνασίου. Οι δραστηριότητες που προτείνονται έχουν σχεδιαστεί λαμβάνοντας υπόψη τις ιδέες των παιδιών, αφορούν στη διδασκαλία της έννοιας της ενέργειας και στη σύνδεσή της με θέματα που σχετίζονται με το περιβάλλον και προτείνονται για διδασκαλία στο πλαίσιο του εβδομαδιαίου προγράμματος του σχολείου.
