description: Most real-world networks are weighted graphs with the weight of the edges reflecting the relative importance of the connections. In this work, we study non degree dependent correlations between edge weights, generalizing thus the correlations beyond the degree dependent case. We propose a simple method to introduce weight-weight correlations in topologically uncorrelated graphs. This allows us to test different measures to discriminate between the different correlation types and to quantify their intensity. We also discuss here the effect of weight correlations on the transport properties of the networks, showing that positive correlations dramatically improve transport. Finally, we give two examples of real-world networks (social and transport graphs) in which weight-weight correlations are present.

description: We describe the minimal space of polylogarithmic functions that is required to express the six-particle amplitude in planar ${\cal N}=4$ super-Yang-Mills theory through six and seven loops, in the NMHV and MHV sectors respectively. This space respects a set of extended Steinmann relations that restrict the iterated discontinuity structure of the amplitude, as well as a cosmic Galois coaction principle that constrains the functions and the transcendental numbers that can appear in the amplitude at special kinematic points. To put the amplitude into this space, we must divide it by the BDS-like ansatz and by an additional zeta-valued constant $\rho$. For this normalization, we conjecture that the extended Steinmann relations and the coaction principle hold to all orders in the coupling. We describe an iterative algorithm for constructing the space of hexagon functions that respects both constraints. We highlight further simplifications that begin to occur in this space of functions at weight eight, and distill the implications of imposing the coaction principle to all orders. Finally, we explore the restricted spaces of transcendental functions and constants that appear in special kinematic configurations, which include polylogarithms involving square, cube, fourth and sixth roots of unity.

description: By placing a ${}^{133}Cs$ $γ$-ray source embedded in a solid at the center of a platinum (gold) cylinder, we try to change the width of the 81-keV level. Our results show a narrowed energy level and, equivalently, a prolonged lifetime. With a 0.5-mm-thick, 5-cm-long, 2-mm-diameter platinum cylinder, we obtain a width narrower by $6.1 % $ at $4.2 \: K$.
Thermal remote sensing of urban surface temperatures
Creators: name: Voogt, James Adrian
Publisher: name: University of British Columbia
Year: 2009

description: Thermal remote sensors have been used extensively to examine urban surface temperature patterns but without explicit consideration of the complex form of the urban surface. This research investigates the extent of possible biases which may be present due to the unique structure of the urban surface and is an attempt to address some of the issues raised by Roth et al. (1989). The research approach is primarily observational. An extensive measurement pro gramme integrating ground and airborne remote sensor platforms as well as fixed monitoring sites was designed and implemented to obtain information from three of the most common urban surface types: downtown Office/commercial, residential and light industrial. Both nadir and off-nadir high resolution thermal imagery was collected to obtain information on component surface temperatures, and to determine the extent of anisotropy in urban surface emissions at the land use scale. Vertical facet temperatures are shown to exhibit large diurnal temperature ranges which strongly control the anisotropic longwave emission of the urban surface. Airborne observations reveal strong anisotropy of surface longwave emissions over each of the sites at times of maximum temperature contrast between opposing canyon facets. The magnitude of the anisotropy is sufficient to demand consideration whenever daytime thermal remote measurements are made over urban surfaces. Mixed distribution modeling has been explored as a technique to recover component surface temperatures from composite temperature frequency distributions. A low number of component distributions can be used to successfully model the composite distribution, however, the successful extraction of individual component temperatures is more difficult and depends upon the nature of the surface, and the temperature contrasts present. Estimates of the complete urban surface temperature have been made for the first time by combining remote and surface-based estimates of horizontal and vertical facet temperatures. The complete surface temperature is cooler than nadir or off-nadir remote measurements and is shown to be best approximated by off-nadir measurements in the direction of the most shaded vertical facet. A simple two-dimensional geometric urban surface model (a slightly modified version of that orignally presented by Sobrino and Caselles (1989) and extended by Caselles et al. (1992) is used to investigate the nature of anisotropy over the study areas. Urban surface temperature components are specified from observed data but a modified version of the Myrup (1969) surface energy balance model is shown to be adequate for estimating surface temperatures in canyon environments for the extension of geometrical surface modeling to other times and locations. Results indicate that the two-dimensional representation of the urban surface is generally inadequate. The development of a three-dimensional surface geometrical model is recommended to better represent the structure of the urban surface.

description: The boundaries of geographical indication (GI) areas represent the core of GI specifications. Theory suggests that smaller areas result in higher prices due to quantity restrictions and higher quality. However, empirical evidence on the importance of GI areas for using places as brands is scarce. Our regressions using newly coded data of GI areas in km2 of 22 hams provide direct empirical evidence that larger areas are associated with lower prices. Subsample regressions suggest that areas affect prices through both quantity and (perceived) quality. Thus, our findings indicate that GI areas are a non-negligible factor in establishing collective regional brands.

description: We show that the accumulation of spin-polarized electrons at a forward-biased Schottky tunnel barrier between Fe and n-GaAs can be detected electrically. The spin accumulation leads to an additional voltage drop across the barrier that is suppressed by a small transverse magnetic field, which depolarizes the spins in the semiconductor. The dependence of the electrical accumulation signal on magnetic field, bias current, and temperature is in good agreement with the predictions of a drift-diffusion model for spin-polarized transport.

description: Simplified Template Cross Sections (STXS) have been adopted by the LHC experiments as a common framework for Higgs measurements. Their purpose is to reduce the theoretical uncertainties that are directly folded into the measurements as much as possible, while at the same time allowing for the combination of the measurements between different decay channels as well as between experiments. We report the complete, revised definition of the STXS kinematic bins (stage 1.1), which are to be used for the upcoming measurements by the ATLAS and CMS experiments using the full LHC Run 2 datasets. The main focus is on the three dominant Higgs production processes, namely gluon-fusion, vector-boson fusion, and in association with a vector boson. We also comment briefly on the treatment of other production modes.

description: We calculate the time evolution of the transient reflection signal in an MoS$_2$ monolayer on a SiO$_2$/Si substrate using first-principles out-of-equilibrium real-time methods. Our simulations provide a simple and intuitive physical picture for the delayed, yet ultrafast, evolution of the signal whose rise time depends on the excess energy of the pump laser: at laser energies above the A- and B-exciton, the pump pulse excites electrons and holes far away from the K valleys in the first Brillouin zone. Electron-phonon and hole-phonon scattering lead to a gradual relaxation of the carriers towards small $\textit{Active Excitonic Regions}$ around K, enhancing the dielectric screening. The accompanying time-dependent band gap renormalization dominates over Pauli blocking and the excitonic binding energy renormalization. This explains the delayed buildup of the transient reflection signal of the probe pulse, in excellent agreement with recent experimental data. Our results show that the observed delay is not a unique signature of an exciton formation process but rather caused by coordinated carrier dynamics and its influence on the screening.

description: We present a new catalogue of variable stars compiled from data taken for the University of New South Wales Extrasolar Planet Search. From 2004 October to 2007 May, 25 target fields were each observed for 1-4 months, resulting in ~87000 high precision light curves with 1600-4400 data points. We have extracted a total of 850 variable light curves, 659 of which do not have a counterpart in either the General Catalog of Variable Stars, the New Suspected Variables catalogue or the All Sky Automated Survey southern variable star catalogue. The catalogue is detailed here, and includes 142 Algol-type eclipsing binaries, 23 beta Lyrae-type eclipsing binaries, 218 contact eclipsing binaries, 53 RR Lyrae stars, 26 Cepheid stars, 13 rotationally variable active stars, 153 uncategorised pulsating stars with periods <10 d, including delta Scuti stars, and 222 long period variableswith variability on timescales of >10 d. As a general application of variable stars discovered by extrasolar planet transit search projects, we discuss several astrophysical problems which could benefit from carefully selected samples of bright variables. These include: (i) the quest for contact binaries with the smallest mass ratio, which could be used to test theories of binary mergers; (ii) detached eclipsing binaries with pre-main-sequence components, which are important test objects for calibrating stellar evolutionary models; and (iii) RR Lyrae-type pulsating stars exhibiting the Blazhko-effect, which is one of the last great mysteries of pulsating star research.

description: We investigate homogeneous and isotropic oscillating cosmologies with multiple fluid components. Transfer of energy between these fluids is included in order to model the effects of non-equilibrium behavior on closed universes. We find exact solutions which display a range of new behaviors for the expansion scale factor. Detailed examples are studied for the exchange of energy from dust or scalar field into radiation. We show that, contrary to expectation, it is unlikely that such models can offer a physically viable solution to the flatness problem.

description: Background:
FMS-like tyrosine kinase 3 receptor-internal tandem duplication (FLT3-ITD) commonly occurs in one-quarter of patients with acute myeloid leukemia. Acute leukemia has a poor prognosis, mainly due to relapse. Single-Cell DNA sequencing technologies such as Tapestri platform enables us to understand the clonal heterogeneity of AML patient samples. Large indel calling is prone to errors from library preparation, sequencing biases, and algorithm artifacts. These errors contribute to false positives often in the form of multiple representations of the same variant. Here we present an algorithm to identify these large indels and reduce false positives to accurately measure the clonal heterogeneity and enable precision diagnostics.

Methods
The Tapestri analytical workflow involves obtaining raw reads from the sequencer, removing adapters, aligning and mapping the reads, calling individual cells and identifying genetic variants within each cell.
We use a soft-clip based approach to detect the internal tandem duplications found in the FLT3 gene. The targeted panel has two amplicons targeting exons 14 and 15 in the FLT3 gene. The soft-clipped reads from these 2 amplicons are scanned for possible insertion events. The observed insertion event is qualified as an ITD variant if the total number of reads at the loci is greater than 10 and at least 20% of the reads support the insertion. The ITD variant is called homozygous if the allele frequency is greater than 0.9 and heterozygous otherwise.
We then apply a generalized median string in Levenshtein space to collapse the different indel variants. The generalized median string is defined as a string that has the smallest sum of distances to the elements of a given set of strings. To do this, we first identify the candidate ITD size bins from the frequency peaks of all the called ITD variants and group the individual variants that are within 20bp boundaries of the frequency peaks into their respective bins. We project the ITD sequence strings within a bin on to Levenshtein vector space domain and calculate the median distance between all strings. We then use the string with the median distance to collapse the ITDs to the consensus sequence and report it in the vcf file.

Results
We processed AML samples with known FLT3 ITDs through Tapestri platform. We analyzed the raw data via Tapestri analytical workflow including our large indel and ITD detection algorithm. Using this method, we were able to accurately identify the ITDs and reproduce the true positive clones for the sample. We are currently optimizing this approach using different samples with a wide range of known ITDs.

description: Single-beam scanning electron microscopes (SEM) are widely used to acquire massive data sets for biomedical study, material analysis, and fabrication inspection. Datasets are typically acquired with uniform acquisition: applying the electron beam with the same power and duration to all image pixels, even if there is great variety in the pixels' importance for eventual use. Many SEMs are now able to move the beam to any pixel in the field of view without delay, enabling them, in principle, to invest their time budget more effectively with non-uniform imaging. In this paper, we show how to use deep learning to accelerate and optimize single-beam SEM acquisition of images. Our algorithm rapidly collects an information-lossy image (e.g. low resolution) and then applies a novel learning method to identify a small subset of pixels to be collected at higher resolution based on a trade-off between the saliency and spatial diversity. We demonstrate the efficacy of this novel technique for active acquisition by speeding up the task of collecting connectomic datasets for neurobiology by up to an order of magnitude.

description: In this paper we present an inductive renormalizability proof for massive $\vp_4^4$ theory on Riemannian manifolds, based on the Wegner-Wilson flow equations of the Wilson renormalization group, adapted to perturbation theory. The proof goes in hand with bounds on the perturbative Schwinger functions which imply tree decay between their position arguments. An essential prerequisite are precise bounds on the short and long distance behaviour of the heat kernel on the manifold. With the aid of a regularity assumption (often taken for granted) we also show, that for suitable renormalization conditions the bare action takes the minimal form, that is to say, there appear the same counter terms as in flat space, apart from a logarithmically divergent one which is proportional to the scalar curvature.

description: The finite remainder function for planar, color-ordered, maximally helicity violating scattering processes in N=4 super Yang-Mills theory possesses a non-vanishing multi-Regge limit that depends on the choice of a Mandelstam region. We analyze the combined multi-Regge collinear limit in all Mandelstam regions through an analytic continuation of the Wilson loop OPE. At leading order, the former is determined by the gluon excitation of the Gubser-Klebanov-Polyakov string. We illustrate the general procedure at the example of the heptagon remainder function at two loops. In this case, the continuation of the leading order terms in the Wilson loop OPE suffices to determine the two-loop multi-Regge heptagon functions in all Mandelstam regions from their symbols. The expressions we obtain are fully consistent with recent results by Del Duca et al.

description: Aim of this project is the study, design and construction of a portable temperature measuring apparatus of infra-red radiation. This experimental device must be reliable, practical, of low budget and highly precise in order to be used in experimental studies and researches. A micro- controller has been designed and programmed, around which the function of the portable device has been coordinated. The specific device is capable of recording the leaf temperature remotely, by use of infra-red radiation. In the same time, measurement of the surrounding space is taking place. The two measurements, as well as the time of the recording, are projected on the screen of the portable device and stored afterwards. Furthermore, the device can be connected to a PC to which all the stored recordings could be transferred for future use or elaboration. Experiments of comparison of the experimental device took place using a temperature measurement device by contact, of big accuracy. The results showed a high fidelity of the experimental model comparing to the ones already existing to the market, giving a r = 0,999 correlation and an error percentage of 0, 7%. Finally, studying the prospects of development, it is highly likely for an automated; infra-red temperature recording system to be applied at a low cost.

description: Inhomogeneous cosmological perturbation equations are derived in loop quantum gravity, taking into account corrections in particular in gravitational parts. This provides a framework for calculating the evolution of modes in structure formation scenarios related to inflationary or bouncing models. Applications here are corrections to the Newton potential and to the evolution of large scale modes which imply non-conservation of curvature perturbations possibly noticeable in a running spectral index. These effects are sensitive to quantization procedures and test the characteristic behavior of correction terms derived from quantum gravity.

description: Offshoring, outsourcing, mergers and acquisitions can rapidly change the spatial organisation of a firm and the reputation of its products. Preserving symbolic resources requires the intentional integration of a firm’s physical geography with its rhetorical geography – a strategy that leverages associations of place to create value for shareholders and stakeholders. We demonstrate how Woolrich, an apparel firm that was once America’s second-oldest clothing manufacturer, was able to capitalise on local geographical claims even as it shuttered its last remaining US manufacturing operations. Pivoting toward rhetorical geography allowed Woolrich to preserve the brand equity of its American origins.

description: We consider the transport of rigid objects with internal structure in a flashing ratchet potential by investigating the overdamped behavior of a rod-like chain of evenly spaced point particles. In 1D, analytical arguments show that the velocity can reverse direction multiple times in response to changing the size of the chain or the temperature of the heat bath. The physical reason is that the effective potential experienced by the mechanically coupled objects can have a different symmetry than that of individual objects. All analytical predictions are confirmed by Brownian dynamics simulations. These results may provide a route to simple, coarse-grained models of molecular motor transport that incorporate an object's size and rotational degrees of freedom into the mechanism of transport.

description: Employing the systematic framework of soft-collinear effective theory (SCET) we perform an improved calculation of the leading-power contributions to the double radiative $B_{d, \, s}$-meson decay amplitudes in the heavy quark expansion. We then construct the QCD factorization formulae for the subleading power contributions arising from the energetic photon radiation off the constituent light-flavour quark of the bottom meson at tree level. Furthermore, we explore the factorization properties of the subleading power correction from the effective SCET current $J^{(A2)}$ at ${\cal O} (α_s^0)$. The higher-twist contributions to the $B_{d, \, s} \to γγ$ helicity form factors from the two-particle and three-particle bottom-meson distribution amplitudes are evaluated up to the twist-six accuracy. In addition, the subleading power weak-annihilation contributions from both the current-current and QCD penguin operators are taken into account at the one-loop accuracy. We proceed to apply the operator-production-expansion-controlled dispersion relation for estimating the power-suppressed soft contributions to the double radiative $B_{d, \, s}$-meson decay form factors. Phenomenological explorations of the radiative $B_{d, \, s} \to γ\, γ$ decay observables in the presence of the neutral-meson mixing, including the CP-averaged branching fractions, the polarization fractions and the time-dependent CP asymmetries, are carried out subsequently with an emphasis on the numerical impacts of the newly computed ingredients together with the theory uncertainties from the shape parameters of the HQET bottom-meson distribution amplitudes.

description: Αυτή η εργασία είχε σκοπό να αναζητήσει τις ιδέες του Πλάτωνα στο έργο του «Πολιτεία». Η μελέτη του έργου αποκαλύπτει δέσμη νοημάτων, τα οποία συνεχίζουν να αποτελούν σημείο αναφοράς για τη στοχαζόμενη ανθρωπότητα. Η θεωρία των Ιδεών αποτελεί τον ακρογωνιαίο λίθο, της «Πολιτείας» και γενικότερα της πλατωνικής φιλοσοφίας. Επάνω σ' αυτήν ο συγγραφέας θεμελίωσε τις διδασκαλίες του για την διαλεκτική, το μύθο, την πολιτεία, την παιδεία. Ο Πλάτων ατένισε τον άνθρωπο ως πράττον υποκείμενο και αναζήτησε τρόπους σύνταξης της πολιτείας του που να συνάδουν προς τη φύση της ψυχής του, του σώματός του, των γνωστικών χαρακτηριστικών του, και τη θέση που κατέχει στη φυσική κλίμακα. Τόνισε ότι η παύση των δεινών από τη φυλακή του σπηλαίου-σώματος, συναρτάται προς τη σωστή παιδεία.
description: This work was aiming to seek the Plato's ideas in his work "Politeia" (State). The study of the work reveals a set of meanings, which continue to be a reference point for meditative humanity. The theory of Ideas forms the cornerstone of the "Politeia" (State) and generally of Platonic philosophy. Up to that the author has based his teachings on the dialectic, the myth, the state, the education. Plato stared at humans as accomplish subject and tried to find ways in compilation his "Politeia" (state) that are consistent with the nature of his soul, his body, cognitive characteristics, and its position in the natural scale. He emphasized that the cessation of suffering from the prison of the cave-body links to proper education.

description: In this note we introduce and study a new class of maps called oriented colored broken submersions. This is the simplest class of maps that satisfies a version of the b-principle and in dimension 2 approximates the class of oriented submersions well in the sense that every oriented colored broken submersion of dimension 2 to a closed simply connected manifold is bordant to a submersion. We show that the Madsen-Weiss theorem (the standard Mumford Conjecture) fits a general setting of the b-principle. Namely, a version of the b-principle for oriented colored broken submersions together with the Harer stability theorem and Miller-Morita theorem implies the Madsen-Weiss theorem.

description: We discuss the use of social media communication for place promotion and place branding of entrepreneurial ecosystems (EEs). As places resting on the advantages of co-location for entrepreneurial activity, EEs offer a novel testbed for the co-creation of a place image in the virtual space of social media. By exploring almost 370,000 tweets from Twitter across 20 European EEs, we observe virtual spaces of EEs being broadly used to share positive messages about the place. However, no EE stands out with a unique image evoking symbolic associations with the place in target audiences. The results suggest the presence of place promotion more than place branding.

description: We present the discovery of a single radio relic located at the edge of the galaxy cluster A2384, using the MeerKAT radio telescope. A2384 is a nearby ($z$ = 0.092), low mass, complex bimodal, merging galaxy cluster that displays a dense X-ray filament ($\sim$ 700 kpc in length) between A2384(N) (Northern cluster) and A2384(S) (Southern cluster). The origin of the radio relic is puzzling. By using the MeerKAT observation of A2384, we estimate that the physical size of the radio relic is 824 $\times$ 264 kpc$^{2}$ and that it is a steep spectrum source. The radio power of the relic is $P_{1.4\mathrm{GHz}}$ $\sim$ (3.87 $\pm$ 0.40) $\times$ 10$^{23}$ W Hz$^{-1}$. This radio relic could be the result of shock wave propagation during the passage of the low-mass A2384(S) cluster through the massive A2384(N) cluster, creating a trail appearing as a hot X-ray filament. In the previous GMRT 325 MHz observation we detected a peculiar FR I radio galaxy interacting with the hot X-ray filament of A2384, but the extended radio relic was not detected; it was confused with the southern lobe of the FR I galaxy. This newly detected radio relic is elongated and perpendicular to the merger axis, as seen in other relic clusters. In addition to the relic, we notice a candidate radio ridge in the hot X-ray filament. The physical size of the radio ridge source is $\sim$ 182 $\times$ 129 kpc$^{2}$. Detection of the diffuse radio sources in the X-ray filament is a rare phenomenon, and could be a new class of radio source found between the two merging clusters of A2384(N) and A2384(S).

Security of quantum bit string commitment depends on the information measure

description: Unconditionally secure non-relativistic bit commitment is known to be impossible in both the classical and the quantum world. However, when committing to a string of n bits at once, how far can we stretch the quantum limits? In this letter, we introduce a framework of quantum schemes where Alice commits a string of n bits to Bob, in such a way that she can only cheat on a bits and Bob can learn at most b bits of information before the reveal phase. Our results are two-fold: we show by an explicit construction that in the traditional approach, where the reveal and guess probabilities form the security criteria, no good schemes can exist: a+b is at least n. If, however, we use a more liberal criterion of security, the accessible information, we construct schemes where a=4 log n+O(1) and b=4, which is impossible classically. Our findings significantly extend known no-go results for quantum bit commitment.

description: Officially branding local heritage through recognised labels is a strategy that regions can use to promote economic development. Regions increasingly seek more sustainable tourism development, which can be captured by the quality of local tourist service development. This paper examines whether the UNESCO World Heritage Site (WHS) label is associated with local tourism development of a higher quality and offers the first comparative study across European regions. Using TripAdvisor reviews of over 38,000 European locations, our results reveal a positive correlation between WHS labelling and measures of perceived quality and breadth of local tourist services.

description: Higher-order exchange interactions and quantum effects are widely known to play an important role in describing the properties of low-dimensional magnetic compounds. Here we identify the recently discovered two-dimensional (2D) van der Waals (vdW) CrI3 as a quantum non-Heisenberg material with properties far beyond an Ising magnet as initially assumed. We find that biquadratic exchange interactions are essential to quantitatively describe the magnetism of CrI3 but requiring quantum rescaling corrections to reproduce its thermal properties. The quantum nature of the heat bath represented by discrete electron-spin and phonon-spin scattering processes induced the formation of spin fluctuations in the low temperature regime. These fluctuations induce the formation of metastable magnetic domains evolving into a single macroscopic magnetization or even a monodomain over surface areas of a few micrometers. Such domains display hybrid characteristics of Neel and Bloch types with a narrow domain wall width in the range of 3-5 nm. Similar behaviour is expected for the majority of 2D vdW magnets where higher-order exchange interactions are appreciable.

description: Η παρούσα εργασία εντάσσεται στη θεματική της εισαγωγής και αξιοποίησης των Τεχνολογιών της Πληροφορίας και των Επικοινωνιών (ΤΠΕ) στην εκπαίδευση. Ο σκοπός της παρούσας εργασίας είναι να αναδειχθεί και να αξιολογηθεί ο τρόπος με τον οποίο προσφέρεται ο Ψηφιακός Γραμματισμός στους μαθητές της Επαγγελματικής Εκπαίδευσης. Επιχειρείται μια προσέγγιση ορισμού του Ψηφιακού Γραμματισμού με βάση τα σύγχρονα κοινωνικά, πολιτισμικά και τεχνολογικά δεδομένα. Επίσης επιχειρείται μια ανάλυση των χαρακτηριστικών των σύγχρονων μαθητών της Επαγγελματικής Εκπαίδευσης αλλά και των εκπαιδευτικών όσον αφορά την κατάρτισή τους. Η εξέλιξη των ΤΕΕ σε ΕΠΑΛ έφερε δραματικές αλλαγές στη διδασκαλία της Πληροφορικής στην Επαγγελματική Εκπαίδευση που άξιζε να μελετηθούν. Για αυτό τον λόγο γίνεται μια κριτική αποτίμηση του προσφερόμενου Ψηφιακού Γραμματισμού, με βάση τον επικαιροποιημένο ορισμό, στην Α' τάξη των ΕΠΑΛ που αποτελεί τάξη-κλειδί. Με αφετηρία τα πορίσματα που προκύπτουν, διατυπώνονται προτάσεις που θα συμβάλουν στην ενίσχυση του Ψηφιακού Γραμματισμού του μαθητή της Επαγγελματικής Εκπαίδευσης.
description: The general aim of the present thesis is to examine the introduction and exploitation of Information and Communications Technologies (ICT) in education. The particular aim of the thesis is to illustrate and evaluate the way in which Digital Literacy is offered to the students of Vocational Education. A definition of Digital Literacy is attempted based on recent social, cultural and technological factors. Moreover, an analysis is attempted concerning the characteristics of contemporary students in Vocational Education in parallel with an analysis upon teachers with regard to their training. The transformation of T.E.E. to EPA.L. brought dramatic changes in the teaching of Information Technology in the Vocational Education that were worth to study. For that reason, a critical assessment of offered Digital Literacy, based on the actualised definition, is conducted on the first grade of EPA.L. which is a key-grade. With the resulting conclusions as a starting line, some proposals are formulated to contribute to the enrichment of Digital Literacy of students in Vocational Education.
