An Exploration of School Staff Experiences Working with Children Who Display Test Anxiety

Test anxiety is relevant to many schools and local authorities. Schools are evaluated in terms of performance by test/exam outcomes and their position in league tables. This has resulted in an increased focus on test results and data. This research examines school staff experiences supporting children with test anxiety and strategies they find useful; how competent they feel in supporting them; what would help build their confidence and understanding of test anxiety; and how EPs can help them to support children with test anxiety. Current literature acknowledges the detrimental impact that test anxiety can have on children, however most of the research has been conducted with secondary school and university students. Furthermore, limited research explores the views of school staff. Much of the aforementioned research employed quantitative techniques and thus school staff experiences of test anxiety has not been explored. A social constructionist paradigm was adopted. To enable a deeper perspective of the phenomena, a qualitative research design was used. Fifteen school staff were selected from three primary schools within the same LA. Semi-structured interviews were used and the recordings were analysed using Thematic Analysis. The findings highlighted the detrimental impact test anxiety has on school staff and children and the high levels of pressure they experience. Barriers and strategies to identify and support children with test anxiety were recognised. There were mixed views on how competent school staff feel supporting children with test anxiety; it was highlighted that teacher training courses do not adequately prepare teachers to deal with mental health issues and test anxiety. School staff would like to see greater collaboration, and further support from the local authority, particularly in terms of funding and changing the narrative around testing. School staff had positive experiences working with EPs to support children with test anxiety although at times key adults were not included in meetings due to school demands. It was argued that school staff prioritise cognitive difficulties and statutory assessments over test anxiety for EP involvement. Areas were identified in terms of support school staff would like from EPs in order to support children with test anxiety

EnzyNet: enzyme classification using 3D convolutional neural networks on spatial representation

During the past decade, with the significant progress of computational power as well as ever-rising data availability, deep learning techniques became increasingly popular due to their excellent performance on computer vision problems. The size of the Protein Data Bank has increased more than 15 fold since 1999, which enabled the expansion of models that aim at predicting enzymatic function via their amino acid composition. Amino acid sequence however is less conserved in nature than protein structure and therefore considered a less reliable predictor of protein function. This paper presents EnzyNet, a novel 3D-convolutional neural networks classifier that predicts the Enzyme Commission number of enzymes based only on their voxel-based spatial structure. The spatial distribution of biochemical properties was also examined as complementary information. The 2-layer architecture was investigated on a large dataset of 63,558 enzymes from the Protein Data Bank and achieved an accuracy of 78.4% by exploiting only the binary representation of the protein shape.

Women's Cooperatives and their Contribution to the Local Development of the North Aegean Region, Greece

In the last twenty years Greece has witnessed the emergence and establishment of women’s cooperatives, a form of productive agricultural cooperatives. This paper explores their importance and their contribution to local development. Evidence is presented for an island region, the North Aegean. Personal interviews, using structured questionnaires, were conducted with the chairwomen of all the region’s cooperatives in order to obtain an insight into their structure and dynamics. According to the findings of this study, women’s cooperatives are characterized by substantial potential on the one hand and by serious drawbacks on the other. The economic performance of the cooperatives is satisfactory, while the use of local resources and ‘know how’ contribute to the development of the region. Interpersonal problems, the inability of the cooperatives’ members to fully understand their new role as businesswomen and the small participation of rural women are the cooperatives’ major problems. The future of the women’s cooperatives is still unclear despite their 20 years of existence.women’s cooperatives, North Aegean, local development, Community/Rural/Urban Development,

Ocular Symptomatology, Management, and Clinical Outcome of a Giant Intracranial Aneurysm

Giant aneurysms of the anterior intracranial circulation are rare, slowly progressive vascular abnormalities, often presenting with neuro-ophthalmological symptoms before they rupture. This is a case of a 55-year-old woman with a double aneurysm of the anterior intracranial circulation, part of which was giant, diagnosed exclusively on the basis of ocular manifestations. We also describe successful management of the case throughout a long follow-up period

Intravitreal Bevacizumab for Photodynamic Therapy-Induced Massive Macular Detachment in Acute Central Serous Chorioretinopathy

We present a long followed up case of acute central serous chorioretinopathy (CSC) complicated by a severe visual loss due to massive pigment epithelium detachment of the macula after a full-dose photodynamic therapy (PDT). Rapid anatomical and functional improvement was observed after a single intravitreal injection of bevacizumab. To our knowledge, we report the first case of PDT-treated CSC complicated by severe visual loss. We can only speculate that the serous detachment of the posterior pole might have been caused by PDT-induced VEGF overexpression, explaining such an impressive response to Avastin treatment

Dental Composites with Calcium / Strontium Phosphates and Polylysine

PURPOSE: This study developed light cured dental composites with added monocalcium phosphate monohydrate (MCPM), tristrontium phosphate (TSrP) and antimicrobial polylysine (PLS). The aim was to produce composites that have enhanced water sorption induced expansion, can promote apatite precipitation and release polylysine. MATERIALS AND METHODS: Experimental composite formulations consisted of light activated dimethacrylate monomers combined with 80 wt% powder. The powder phase contained a dental glass with and without PLS (2.5 wt%) and/or reactive phosphate fillers (15 wt% TSrP and 10 wt% MCPM). The commercial composite, Z250, was used as a control. Monomer conversion and calculated polymerization shrinkage were assessed using FTIR. Subsequent mass or volume changes in water versus simulated body fluid (SBF) were quantified using gravimetric studies. These were used, along with Raman and SEM, to assess apatite precipitation on the composite surface. PLS release was determined using UV spectroscopy. Furthermore, biaxial flexural strengths after 24 hours of SBF immersion were obtained. RESULTS: Monomer conversion of the composites decreased upon the addition of phosphate fillers (from 76 to 64%) but was always higher than that of Z250 (54%). Phosphate addition increased water sorption induced expansion from 2 to 4% helping to balance the calculated polymerization shrinkage of ~ 3.4%. Phosphate addition promoted apatite precipitation from SBF. Polylysine increased the apatite layer thickness from ~ 10 to 20 μm after 4 weeks. The novel composites showed a burst release of PLS (3.7%) followed by diffusion-controlled release irrespective of phosphate addition. PLS and phosphates decreased strength from 154 MPa on average by 17% and 18%, respectively. All formulations, however, had greater strength than the ISO 4049 requirement of > 80 MPa. CONCLUSION: The addition of MCPM with TSrP promoted hygroscopic expansion, and apatite formation. These properties are expected to help compensate polymerization shrinkage and help remineralize demineralized dentin. Polylysine can be released from the composites at early time. This may kill residual bacteria

THE LOCUS OF HABITUATION IN THE GIANT FIBER CIRCUIT OF DROSOPHILA

Ο μηχανισμός της εξοικείωσης είναι μια μορφή μη-συνειρμικής μάθησης, συντηρημένη εξελικτικά. Με τη χρήση τεχνικών ηλεκτροφυσιολογίας σε οργανισμούς όπως η Δροσόφιλα έχουν βρεθεί διάφορα γονίδια που φαίνεται να εμπλέκονται στην εξοικείωση. Το σύστημα γιγαντιαίων αξόνων (ΣΓΑ) στη Δροσόφιλα, το οποίο είναι ένα καλά χαρακτηρισμένο, αισθητικοκινητικό κύκλωμα είναι υπεύθυνο για την διαφυγή της μύγας. Αυτή η απόκριση της μύγας μπορεί να υποστεί εξοικείωση, και το ΣΓΑ έχει χρησιμοποιηθέι εκτενώς για τη διερεύνηση διάφορων γονιδίων στο μηχανισμό της εξοικείωσης. Ωστόσο, η τοποθεσία της εξοικείωσης παραμένει άγνωστη. Στη συγκεκριμένη έρευνα αξιοποιήσαμε σύγχρονες γενετικές τεχνικές και μεθόδους ηλεκτροφυσιολογίας με σκοπό να ανακλύψουμε το κυτταρικό υπόστρωμα της εξοικείωσης του ΣΓΑ. Υποεκφράσαμε το γονίδιο που κωδικοποιεί τους Shaker A-type διαύλους, χρησιμοποιώντας RNAi και αξιοποιώντας το σύστημα UAS-GAL4. Ακολούθως στοχεύσαμε στους προσυναπτικούς των γιγαντιαίων νευρώνων πληθυσμούς νευρώνων οι οποίοι είναι οι LPLC2 (lobula plate/lobula columnar, type 2) και οι LC4 (lobula columnar, type 4). Η ανάλυση που προέκυψε από τις ηλεκτροφυσιολογικές μελέτες κατέδειξε ότι η υποέκφραση των shaker διαύλων στους LC4 αλλά όχι στους LPLC2 νευρώνες, εξαλείφει την εξοικείωση που υφίσταται ο ΣΓΑ. Αυτό δείχνει ότι ο πληθυσμός των 55 LC4 νευρώνων που δημιουργεί περίπου 2500 συνάψεις πάνω στους γιγαντιαίους νευρώνες αποτελεί το κυτταρικό υπόστρωμα στο οποίο υφίσταται ο μηχανισμός της εξοικείωσης του ΣΓΑ. Η έρευνά μας αποτελεί το υπόβαθρο για περαιτέρω διερεύνηση των μοριακών μηχανισμών σε συναπτικό επίπεδο συγεκριμένων νευρώνων.Habituation, the response decrement after repeated stimulation, is the most primitive non-associative form of learning, conserved across species. Electrophysiological studies in model organisms such as Drosophila melanogaster have revealed various genes and mechanisms implicated in habituation. The giant fiber system (GFS) of Drosophila, a well-defined, electrophysiologically amenable, sensory-motor circuit underlies the fly’s escape response. The response can be habituated, and the GFS has been extensively used as a model to study the contribution of several genes in habituation. However, the locus of habituation has been elusive. In the current study we employed a combination of recently available genetic tools in Drosophila and electrophysiology to unravel the cellular substrate of GFS habituation. We downregulated the expression of Shaker A-type channel (homologous to vertebrate Kv1) with RNAi using the binary GAL4-UAS system. We targeted the presynaptic neurons to the giant fiber LPLC2 (lobula plate/lobula columnar, type 2) and LC4 (lobula columnar, type 4). The electrophysiological analysis revealed that shaker downregulation in LC4, but not in LPLC2, neurons eliminates habituation of the giant fiber circuit. This suggests that the group of the 55 LC4 neurons that make ~2500 synaptic contacts with the giant fiber dendrites is the cellular locus of GFS habituation. Our study lays the ground for in depth analysis of the molecular mechanisms underlying habituation at the synaptic level in identified neurons

Ζητήματα δικονομικού διεθνούς δικαίου όσον αφορά την προσβολή της προσωπικότητας ιδίως μέσω του διαδικτύου

Τα socialmedia, οι ειδησεογραφικοί ιστότοποι, οι πλατφόρμες κοινωνικής δικτύωσης συμβάλλουν στην αφιλτράριστη και άμεση διάχυση της πληροφορίας, καταργώντας τα κρατικά σύνορα, καθιστώντας έτσι το ρόλο του ιδιωτικού διεθνούς δικαίου ιδιαίτερα σημαντικό για την αναζήτηση λύσεων στο πεδίο των προσβολών της προσωπικότητας. Με δεδομένο ότι πλέον ο προσδιορισμός του τόπου όπου έχει λάβει χώρα η προσβολή «κρύβεται» πίσω από μια οθόνη, ιδιαίτερα σημαντική αναδεικνύεται η προβληματική η ανεύρεση της διεθνούς δικαιοδοσίας, της εξουσίας, δηλαδή, και του δικαιώματος απονομής δικαιοσύνης εντός μιας σαφώς καθορισμένης επικράτειας, ιδίως όταν αυτή έχει να συγκρουστεί με μια «αόρατη και άυλη», όμως ισχυρά εδραιωμένη πραγματικότητα στην οποία λαμβάνουν χώρα οι εκάστοτε προσβολές, εκείνη του κυβερνοχώρου Στην παρούσα, εργασία γίνεtai μια προσπάθεια προσέγγισης των ακανθωδών αυτών ζητημάτων μέσω μια αρχικής ανάλυσης του δικαιώματος της προσωπικότητα υπό το πρίσμα της επίδρασης του κυβερνοχώρου στις προσβολές αυτής και στη συνέχεια θα εξεταστεί πώς η σύγχρονη ευρωπαϊκή έννομη τάξη ανταποκρίνεται στις ραγδαίες αυτές προκλήσεις κατά τη διαδικασία ανεύρεσης της διεθνούς δικαιοδοσίας, μέσω της σύγκρουσης μιας διαχρονικής και σταθερής αξίας, όπως το δικονομικό διεθνές δίκαιο, με μια ριζοσπαστικά μεταβαλλόμενης, εκείνης του διαδικτύου.Social media, news sites, social networking platforms contribute to the unfiltered and immediate dissemination of information, removing state borders, thus making the role of private international law particularly important in the search for solutions in the field of personality offences. Given that the determination of the place where the insult has taken place is now 'hidden' behind a screen, the problem of finding jurisdiction, i.e. the power and right to administer justice within a clearly defined territory becomes particularly important, especially when it has to clash with an 'invisible and intangible' but strongly established reality in which the insults in question take place, that of cyberspace. This dissertation will attempt to approach these thorny issues through an initial analysis of the right of personality in the light of the impact of cyberspace on the attacks on it, and then examine how the contemporary European legal order responds to these rapid challenges in the process of finding international jurisdiction through the conflict between a timeless and stable value, such as procedural international law, and a radically changing one, that of the Internet
