description: The article constitutes a part of the theoretical frame of a project con¬cerning the interaction of mathematic education with the school failure in the islander region of Dodecanese. The study of factors that contribute in the failure, as well as the development of the criteria for the selection of variables’ aiming to ameliorative actions is the aim of this project.
In the particular article the argumentation is focused in two fundamental issues. The first one concerns the statement that student’s or even his fami¬ly’s necessary movements -from city to city and mainly from island to island- for the completion of his school route, constitute an important fac¬tor of interpretation as far as the phenomenon of school failure is con¬cerned. The second issue is related to the effort needed for the construction of a model that can depict the variety of school routes.
The treatment of the above issues entails the existence of a great variety of school routes. The majority of them -which are hard enough- might con¬stitute a factor for the interpretation of school failure phenomenon since are related to the student’s and his family’s decision regarding the completion or not of his school duties. Therefore, the taking of the required welfare measures is deemed to be of high importance for the balance of the above mentioned factor.

description: In this paper, an upper bound for the number of integral points of bounded height on an affine complete intersection defined over $\mathbb{Z}$ is proven. The proof uses an extension to complete intersections of the method used for hypersurfaces by Heath-Brown, the so called q-analogue of van der Corput's AB process.

description: Η μελέτη αυτή επικεντρώθηκε στη διερεύνηση των αναπαραστάσεων των μαθητών για την σχολική διαρροή. Στόχος της ήταν να μελετήσει ένα φαινόμενο που έχει ερευνηθεί κυρίως από μακροκοινωνική σκοπιά, από την πλευρά των μαθητών σε μικροκοινωνικό επίπεδο. Με άλλα λόγια στόχος της ήταν να εξετάσει πώς οι ίδιοι οι μαθητές ερμηνεύουν φαινόμενα σχολικής εγκατάλειψης. Για τους σκοπούς της έρευνας πραγματοποιήθηκαν συνεντεύξεις με 37 μαθητές και μαθήτριες μεταξύ 13 και 21 χρονών που φοιτούσαν σε Γυμνάσια και Λύκεια περιοχών της Θεσσαλονίκης αλλά και της Σκύδρας. Η ανάλυση των συνεντεύξεων βασίστηκε στις αρχές της ποιοτικής ανάλυσης περιεχομένου και της θεμελιωμένης θεωρίας. Σύμφωνα με τα αποτελέσματα της ανάλυσης οι συμμετέχοντες στην έρευνα δομούν τις αντιλήψεις τους σχετικά με την σχολική διαρροή γύρω από τρεις βασικές κατηγορίες, το σχολικό, το οικογενειακό και το ευρύτερο κοινωνικό περιβάλλον. Αποδίδουν όμως την ευθύνη της εκπαίδευσης των μαθητών κυρίως στο οικογενειακό περιβάλλον και τη συνδέουν με την οικονομική κατάσταση της οικογένειας. Με άλλα λόγια η οικονομική κατάσταση των γονέων αναπαρίσταται ως αυτή που σημαντικά καθορίζει αν ένα παιδί θα μπορέσει να συνεχίσει το σχολείο και να προχωρήσει στην τριτοβάθμια εκπαίδευση.
description: This study is focused on the investigation of students' representations concerning dropout. The objective was to study a phenomenon, which has been investigated mainly macro-socially, from the students’ perspective in micro-social level. In other words, its aim was to examine how students interpret dropout phenomena. For the purpose of the survey, 37 students aged between 13 and 21 who attended secondary school areas of Thessaloniki and Skydra, were interviewed. The interviews’ analysis was based on the principles of qualitative content analysis and grounded theory. According to the results of the analysis, research participants formulate their perceptions concerning school dropout in three main categories, school, family and social environment. However, students’ educational responsibility is mainly attributed to students’ family and financial background. In other words, the economic status of the parents is represented as the determining factor as to whether a child continue school and proceed to higher education.

description: The aim of the present paper was the study of successive insurance, i.e. the change of social security carrier. In the beginning we presented its definition and the basic principle of freedom of choice on behalf of the policyholder. Furthermore, we mentioned its field of application and its exceptions. We presented in detail the calculation of the period of successive insurance, the competent carrier to provide a pension and the calculation of the pension's sum. We also mentioned the distribution of the pension's financing among the social security carriers, as well as the administrative and legal procedure of difference solving. In the end, we examined some of the practical problems of this institution.

description: We present a total of 4784 unique broad absorption line quasars from the Sloan Digital Sky Survey Third Data Release. An automated algorithm was used to match a continuum to each quasar and to identify regions of flux at least 10% below the continuum over a velocity range of at least 1000 km/s in the CIV and MgII absorption regions. The model continuum was selected as the best-fit match from a set of template quasar spectra binned in luminosity, emission line width, and redshift, with the power-law spectral index and amount of dust reddening as additional free parameters. We characterize our sample through the traditional ``balnicity'' index and a revised absorption index, as well as through parameters such as the width, outflow velocity, fractional depth and number of troughs. From a sample of 16883 quasars at 1.74.38 quasars with broad CIV absorption. We find that broad absorption line quasars may have broader emission lines on average than other quasars.

description: Recently, researchers have found time cells in the hippocampus that appear to contain information about the timing of past events. Some researchers have argued that time cells are taking a Laplace transform of their input in order to reconstruct the past stimulus. We argue that stimulus prediction, not stimulus reconstruction or redundancy reduction, is in better agreement with observed responses of time cells. In the process, we introduce new analyses of nonlinear, continuous-time reservoirs that model these time cells.
17-electron chromium nitrosyl complexes

description: Reaction of [CpCr(NO)I]₂ with an excess of ammonia or allylamine yields the complex salts [CpCr(NO)L₂]⁺[I]⁻ (L = NH₃, NH₂C₃H₅) . Heating these salts results in loss of L and formation of the neutral complexes, CpCr(NO)(L)I. In contrast, reaction of [CpCr(NO)I]₂ with the bulkier amine NH₂CMe₃ affords CpCr(NO)(lS[NH₂CMe₃)I directly. Sequential reaction of CpCr(NO)( NH₂CMe₃)I or CpCr(NO)(P{OMe}3)I with AgPF₆ and further L affords, respectively, the salts [CpCr(NO)(L)₂]⁺[PF₆]⁻(L = NH₂CMe₃, L = P(OMe)₃). All these species exhibit room-temperature ESR spectra and magnetic moments consistent with their possessing 17-valence-electron configurations. Abstraction of a proton from the amine ligand of [CpCr(NO)L₂]+ and CpCr(NO)(L)I (L = amine) compounds results in the formation of amidebridged dimers [CpCr(NO)(NHR)]₂, which exist as mixtures of various cis- and /raws-isomers. Reduction of [CpCr(NO)(NH₃)₂]⁺ to an 18-electron configuration results in loss ofNH₃, so that CpCr(NO)(CO)₂ s formed in the presence of CO. In a reverse manner, oxidation of CpCr(NO)(CO)₂ in acetonitrile produces [CpCr(NO)(NCMe)₂]⁺[PF₆]-. These observations suggest that for CpCr(NO)L₂ complexes, a-basic ligands stabilize the 17-electron configurations of cations whereas π-acidic ligands stabilize the 18-electron configurations of the neutral congeners. This trend can be rationalized by the results of an Extended Hiickel molecular orbital analysis of the CpCr(NO) fragment and the interaction of its frontier orbitals with those of various ligands, L.

description: We analyze a singular theory with first class constraints of an arbitrary stage. Relation among the formulations of the constrained system in terms of complete and extended Hamiltonians is clarified. We replace the extended Hamiltonian $H_{ext}$ by an improved one. The improved Hamiltonian has the same structure as $H_{ext}$ (higher stage constraints enter into the Hamiltonian in the manifest form), but, in contrast to $H_{ext}$, it arises as the complete Hamiltonian for some Lagrangian $\tilde L$, called the extended Lagrangian. This implies, in particular, that all the quantities appearing in the improved Hamiltonian have a clear meaning in the Dirac framework. $\tilde L$ is obtained in a closed form in terms of quantities of the initial formulation $L$. The formulations with $L$ and $\tilde L$ turn out to be equivalent. As an application of the formalism, we found local symmetries of $\tilde L$ in a closed form. All the constraints of $L$ turn out to be gauge symmetry generators for $\tilde L$. The procedure is illustrated with an example of a model with fourth-stage constraints.

description: We construct a range of supersymmetric cubic vertices for three massless higher spin supermultiplets in the four-dimensional space. We use frame-like multispinor formalism, which allows to avoid most of the technical difficulties and provides a uniform description for bosons and fermions. Our work is based on the so-called Fradkin-Vasiliev formalism for construction of the cubic vertices, which requires the non-zero cosmological constant. Thus we first construct the vertices in AdS space and then consider the flat limit. We show that the AdS supersymmetric vertex is a sum of four elementary vertices for supermultiplet components, while one of the vertices vanishes in the flat limit in agreement with the Metsaev's classification.

description: The aim of the present thesis was to study the institution of arbitration, both in international and domestic law and especially the case of challenge and disqualification of arbitratorsTherefore,we initially examined the general framework of the arbitration, the advantages and disadvantages of this. Then we presentedin detailhow to set the arbitrators, and then emphasized the possibility of such a challenge based on a number of grounds.We dealt with the challenge procedure, its effect on the arbitral proceeding andthe consequences of a successful challenge. We discussed further in the case of cancellation of an arbitration award made by an arbitrator disqualified. Eventually we found the agreement of the arbitrators’ challenge to the constitutional requirements and in particular, the presence of the necessary requirements of the principle of impartiality and independence of arbitrators.

description: This paper is dedicated to the memory of Dietrich Stauffer, who was a pioneer in percolation theory and applications of it to problems of society, such as epidemiology. An epidemic is a percolation process gone out of control, that is, going beyond the critical transition threshold $p_c$. Here we discuss how the threshold is related to the basic infectivity of neighbors $R_0$, for trees (Bethe lattice), trees with triangular cliques, and in non-planar lattice percolation with extended-range connectivity. It is shown how having a smaller range of contacts increases the critical value of $R_0$ above the value $R_{0,c}=1$ appropriate for a tree, an infinite-range system or a large completely connected graph.

description: Background: In Liberia, soups are considered as identity traits. There are at least 20 soups in Liberia. Few of themare attached to particular tribes. Regardless of existing beliefs of them, majority of the population does not havesufficient knowledge of their consumption level as well as the importance these soups have on the human body.Methods: Both qualitative and quantitative research approaches were utilized in this study. The DescriptiveResearch Design was used during the research process in order to illustrate the frequency, central tendency andspread of data, plot, table and percentage of variables. The purposive non-probability sampling method was used toselect the study population. Jamovi 2.3.2 and Microsoft Excel 2010 were used to do the data analysis.Results: This study showed that potato greens (21.4%), followed by cassava leaf (16.6%) and torgborgee (16.6%)are the three most favorite soups of 14 Gobachop Marketers. It further indicated that the soups that are mostlyconsumed among the respondents (more than 6 times per month) are potato greens (50.2%), torgborgee (34.3%),cassava leaf (29.8%) and beans (25.3%). All of the traditional Liberian soups were classified into three groups;namely, thick, thin and special soups. The importance of these soups were well stated.Conclusion: Identifying the frequency of the consumption of traditional Liberian soups is a better way to help allLiberians to know which soups are mostly consumed by the population on a monthly basis and their importancethereof to the human body. This research is serving as a baseline study to inform the decisions of major stakeholderswhen developing a national food guide in the future.

description: The thermal expansion at constant pressure of solid CD$_4$ III is calculated for the low temperature region where only the rotational tunneling modes are essential and the effect of phonons and librons can be neglected. It is found that in mK region there is a giant peak of the negative thermal expansion. The height of this peak is comparable or even exceeds the thermal expansion of solid N$_2$, CO, O$_2$ or CH$_4$ in their triple points. It is shown that like in the case of light methane, the effect of pressure is quite unusual: as evidenced from the pressure dependence of the thermodynamic Grüneisen parameter (which is negative and large in the absolute value), solid CD$_4$ becomes increasingly quantum with rising pressure.

Subjects: subject: Quantum Physics (quant-ph)

description: We investigate the asymmetry properties of quantum states in relation to the Hamiltonian responsible for the magnetic dipolar interaction (MDI) dynamics, and we evaluate its relationship to entanglement production. We consider some classes of pure and mixed quantum states of two qubits evolved under MDI and, using the asymmetry measure defined via the Wigner-Yanase skew information, we describe the asymmetry dependence on the Hamiltonian parameters and initial conditions of the system. In addition, we define and calculate the dynamics of the asymmetry of local states, characterizing their temporal and interaction parameters dependence. Finally, because the MDI Hamiltonian has a null eigenvalue, the group generator-based asymmetry measure does not adequately quantify the state susceptibility with respect to the action of the subspace generated by the eigenvectors associated with this eigenvalue. For this reason, we also define and study the group element-based asymmetry measure with relation to the unitary operator associated with the MDI Hamiltonian.

E-commerce typically uses the internet at least at some point in the transaction's lifecycle, although it can encompass a wider range of technologies such as e-mail as well. At first we examined the definition of the so called e-commerce and the applicable law. Moreover, after analyzing the way parts contract on line, we contemplated on the definitions of electronic signatures and electronic authentication and mainly on consumer’s protection according to the Distance Selling Regulation. Also we examined jurisdiction and the applicable law.

description: Is transitional truth-telling more beneficial to reconciliation than remaining silent about past crimes? The aim of this article is to contribute to the debate by exploring the impact of “My Story,” an NGO initiative that uses multiethnic storytelling by victims of the Bosnian war to promote reconciliation. We report field observations and the results obtained from interviews with young Bosniaks, Croats and Serbs. Empathy, as a reported outcome of the storytelling, seems to enable deeper reflection and attitude change. Respondents reported reduced prejudice, competitive victimhood and blaming, and increased interest in information about the outgroup, increased interest in peace activism, a change of emotions toward the outgroup and feeling guilt for the misdeeds of their ingroup. We conclude that this storytelling initiative is beneficial and worth spreading internationally. It deconstructs many of the same factors that prevent reconciliation that truth commissions aim to deconstruct, while improving interethnic attitudes and enabling to look toward the future, as forgetting does.

description: Το σύγχρονο δημοσιογραφικό επάγγελμα αλλάζει, καθώς μεταβάλλονται οι συνθήκες μέσα στις οποίες εξελίσσεται. Οι συνθήκες αυτές αφορούν τόσο στο πολιτικό, το οικονομικό και κοινωνικό πεδίο, όσο και το τεχνολογικό. Το διαδικτύο επέφερε ριζικές αλλαγές στον τρόπο με τον οποίο οι επαγγελματίες της ενημέρωσης ασκούν το δημοσιογραφικό επάγγελμα. Η παρούσα εργασία εστιάζει στη διαδικασία της αναπαραγωγής του ίδιου ή παρόμοιου ειδησεογραφικού υλικού από τα Μέσα Μαζικής Επικοινωνίας, ειδικά από τους ειδησεογραφικούς δικτυακούς τόπους στην Ελλάδα. Η διαδικασία αυτή έχει αποδοθεί με τον όρο churnalism. Στην εργασία αυτή περιγράφεται η προβληματική πρακτική churnalism με τη συμβολή της θεωρίας της δημόσιας σφαίρας. Επιπλέον, αναλύονται οι παράγοντες που συνέβαλαν στην εξέλιξη του φαινομένου, καθώς επίσης οι επιπτώσεις του φαινομένου στη δημοσιογραφική πρακτική. Στο ερευνητικό μέρος της εργασίας, μελετώνται 300 ειδήσεις από δέκα δημοφιλείς δικτυακούς τόπους στην Ελλάδα. Σκοπός της έρευνας είναι ο εντοπισμός του ποσοστού των ειδήσεων εκείνων που είναι αντιγραμμένες από άλλες πηγές (π.χ. από άλλους δικτυακούς τόπους, το Αθηναϊκό-Μακεδονικό Πρακτορείο Ειδήσεων και Γραφεία Τύπου πολιτικών κομμάτων). Ουσιαστικά, πρόκειται να ελεγχθεί ο βαθμός εξάρτησης των δικτυακών τόπων από άλλες πηγές.
description: The modern journalistic profession is changing, as the conditions in which it is evolving change as well. These conditions concern both the political, financial and social field, as well as the technological field. The Internet brought about radical changes in the way in which the professionals of information practice the journalistic profession. This thesis focuses on the process of reproduction of the same or similar news material by the mass media, especially by news websites in Greece. This process has been attributed to the term churnalism. In this thesis the problematic practice of churnalism is being described with the contribution of the public sphere theory. Furthermore, the factors which have contributed to the evolution of the phenomenon are analyzed, as well as the impact of the phenomenon in the journalistic practice. In the research part of the thesis, 300 news items from ten popular websites in Greece are being studied. The purpose of the research is to identify the proportion of those news items which are copied from other sources (e.g. other websites, the Athens-Macedonian News Agency and Press Offices from political parties). Basically, what is going to be examined is the degree of the dependency of websites on other sources.

description: Using experiments and theory, we show that light scattering by inhomogeneities in the index of refraction of a fluid can drive a large-scale flow. The experiment uses a near-critical, phase-separated liquid, which experiences large fluctuations in its index of refraction. A laser beam traversing the liquid produces a large-scale deformation of the interface and can cause a liquid jet to form. We demonstrate that the deformation is produced by a scattering-induced flow by obtaining good agreements between the measured deformations and those calculated assuming this mechanism.

description: In this paper, we investigate a large intelligent surface-enhanced (LIS-enhanced) system, where a LIS is deployed to assist secure transmission. Our design aims to maximize the achievable secrecy rates in different channel models, i.e., Rician fading and (or) independent and identically distributed Gaussian fading for the legitimate and eavesdropper channels. In addition, we take into consideration an artificial noise-aided transmission structure for further improving system performance. The difficulties of tackling the aforementioned problems are the structure of the expected secrecy rate expressions and the non-convex phase shift constraint. To facilitate the design, we propose two frameworks, namely the sample average approximation based (SAA-based) algorithm and the hybrid stochastic projected gradient-convergent policy (hybrid SPG-CP) algorithm, to calculate the expectation terms in the secrecy rate expressions. Meanwhile, majorization minimization (MM) is adopted to address the non-convexity of the phase shift constraint. In addition, we give some analyses on two special scenarios by making full use of the expectation terms. Simulation results show that the proposed algorithms effectively optimize the secrecy communication rate for the considered setup, and the LIS-enhanced system greatly improves secrecy performance compared to conventional architectures without LIS.

description: We study weakly-repulsive Bose-Bose mixtures in two and three dimensions at zero temperature using the functional renormalization group (FRG). We examine the RG flows and the role of density and spin fluctuations. We study the condition for phase separation and find that this occurs at the mean-field point within the range of parameters explored. Finally, we examine the energy per particle and condensation depletion. We obtain that our FRG calculations compare favorably with known results from perturbative approaches for macroscopic properties.

description: The purpose of the present research was to examine to what extent the coexistence of children with special needs (SEN) and children without SEN can change the attitude of the latter towards acceptance. The research find¬ings indicated that children without SEN who accept the integration of chil¬dren with SEN in their classes, develop a more positive attitude than those who don’t accept them in their classes despite their being at the same school as far as school activities are concerned. However, their acceptance regard¬ing social interaction outside the school setting is reduced. This fact shows that while the functional integration of children with SEN in (mainstream) schools is often achieved, these children remain socially isolated.

description: A magnetic field gradient applied to an atom interferometer induces a $M$-dependent phase shift which results in a series of decays and revivals of the fringe visibility. Using our lithium atom interferometer based on Bragg laser diffraction, we have measured the fringe visibility as a function of the applied gradient. We have thus tested the isotopic selectivity of the interferometer, the velocity selective character of Bragg diffraction for different diffraction orders as well as the effect of optical pumping of the incoming atoms. All these observations are qualitatively understood but a quantitative analysis requires a complete model of the interferometer.

description: We predict the two-photon width of the pseudoscalar bottomonia, Gamma(eta_b -> gamma gamma), Gamma(eta'_b -> gamma gamma) and Gamma(eta''_b -> gamma gamma) within a Heavy-Quark Spin-Symmetry setting following the same line as our recent work for the corresponding decays for charmonia. Binding-energy effects are included for excited states and are shown to shift up the eta'_b and eta''_b widths by 10 %. We point out that the essentially model independent ratio Gamma(eta_b -> gamma gamma)/Gamma(Upsilon -> ll) and the branching ratio BR(eta_b -> gamma gamma) obtained could be used to extract the coupling constant alpha_s.

description: Among the many remarkable properties of diamond, the ability to superconduct when heavily doped with boron has attracted much interest in the carbon community. When considering the nanocrystalline boron doped system, the reduced dimensionality and confinement effects have led to several intriguing observations most notably, signatures of a mixed superconducting phase. Here we present ultra-high-resolution transmission electron microscopy imaging of the grain boundary and demonstrate how the complex microstructure leads to enhanced carrier correlations. We observe hallmark features of spin-orbit coupling (SOC) manifested as the weak anti-localization effect. The enhanced SOC is believed to result from a combination of inversion symmetry breaking at the grain boundary interfaces along with antisymmetric confinement potential between grains, inducing a Rashba-type SOC. From a pronounced zero bias peak in the differential conductance, we demonstrate signatures of a triplet component believed to result from spin mixing caused by tunneling of singlet Cooper pairs through such Rashba-SOC grain boundary junctions.

description: Asymmetric magnetization reversal is an unusual phenomenon in antiferromagnet / ferromagnet (AF/FM) exchange biased bilayers. We investigated this phenomenon in a simple model system experimentally and by simulation assuming inhomogeneously distributed interfacial AF moments. The results suggest that the observed asymmetry originates from the intrinsic broken symmetry of the system, which results in local incomplete domain walls parallel to the interface in reversal to negative saturation of the FM. Magneto-optic Kerr effect unambiguously confirms such an asymmetric reversal and a depth-dependent FM domain wall in accord with the magnetometry and simulations.

description: Accurate and timely detection of malaria is crucial for effective disease management. Researchers havebeen implementing computational models to help doctors in diagnosing malaria. There are two importantchallenges: 1) collecting labeled data is expensive, and 2) many models remain as black boxes and are notinherently transparent or interpretable to humans. Using the Malaria Cell Images Dataset from Kaggle, wefirst explore the use of semi-supervised learning to obtain high accuracy with limited labeled data andexamine different methods to efficiently select candidates for labeling. Second, we employ Explainable AItools to improve the transparency of these models. We use Explainable AI on a fully supervised model.For semi-supervised learning, we adapted the state-of-the-art FixMatch model for our data and achieved96% accuracy with 4000 (25%) labeled data, which is comparable to the best result on the same dataset.For Explainable AI, we apply Grad-Cam and SHAP to give detailed insights into our model. Removingthe transparency in our model will allow for its improvement and further understanding for classifyingmalaria for researchers and patients.

Myanmar’s history since its independence in 1948 has been characterised predominantly by political instability and violent internal conflicts involving ethnic armed organisations (EAOs) and the Myanmar military. As a result of the 2021 coup, 98% of Myanmar children, including approximately 11.4 million school-aged children, are affected by the ongoing crisis. Over 3.5 million are out-of-school and 6.5 million are experiencing learning deprivation despite attending school (Valenza and Stoff, 2023). Schools have been caught in the conflicts between armed resistance actors and the State Administration Council (SAC) military junta. Moreover, educational provisions have become heavily politicised, often used to serve the ideologies and political visions of different armed groups, making education a victim of political controversies as well as the ongoing violence. There is an urgent need for a robust evidence base to help education providers – and those that support them – navigate the barriers to education and mitigate disruptions to teaching and learning amid ongoing violence.This review draws upon relevant studies conducted since 2000 as well as complementary findings from journalistic writing and key informant interviews conducted in 2024. It organises, describes and analyses the current evidence base for education in Myanmar and identifies evidence gaps for future research. It looks primarily at three educational settings affected by conflict and crisis contexts:non-state ethnic minority education provided by various actors in areas contested by or under the control of different EAOs, operating in parallel to the central state education system;refugee education provided in the nine refugee camps on the Thailand side of Myanmar’s border, overseen by two ethnic minority refugee committees (Karen and Karenni); andmigrant education in Thailand’s Tak Province, consisting of over 60 learning centres
