‘Space is a Practiced Place’
No full textThis paper seeks to explore a recent collaborative research-by-practice project conducted in the Hyde Park area of Leeds. Building on the Situationists’ theories, and particularly that of the dérive and that of groups of psychogeographers such as the Milwaukee Association of Psychogeographers (MAP), and various other urban exploration groups, Sophia Emmanouil and Aggeliki Aggeli set off on a journey of urban exploration and experimentation in order to test the above theories and develop alternative ways of engaging with the environment

Οργάνωση και διοίκηση των δημόσιων σχολικών βιβλιοθηκών της Κύπρου
No full textΠεριέχει βιβλιογραφικές παραπομπές.Η βιβλιοθήκη σε ένα σύγχρονο σχολείο, με ανοικτούς ορίζοντες είναι η καρδιά του. Είναι ένα κατευθυντήριο πνευματικό κέντρο, το οποίο με το εύρος του υλικού και τις πολλαπλές δραστηριότητες που ο βιβλιοθηκονόμος έχει τη δυνατότητα να αναπτύξει, μπορεί να εμπεδώσει τη διδασκόμενη ύλη, να διευρύνει τους ορίζοντες των μαθητών, να ευκολύνει τους διδάσκοντες στο εκπαιδευτικό τους έργο και να δημιουργήσει τις βάσεις για την αναζήτηση του «νέου».
Η ιδιαίτερη σημασία που αποκτά η σχολική βιβλιοθήκη στην εκπαιδευτική διαδικασία οδήγησαν στην πραγματοποίηση της παρούσας έρευνας. Στόχοι της, να παρουσιάσει την υπάρχουσα κατάσταση στο χώρο των σχολικών βιβλιοθηκών της Κύπρου, να συνεισφέρει στο ρόλο που πρέπει να διαδραματίζει η σχολική βιβλιοθήκη σήμερα και να υποδείξει την αναγκαιότητα στελέχωσής της από επαγγελματίες βιβλιοθηκονόμους.
Αυτή η ερευνητική εργασία παρουσιάζει τα αποτελέσματα μιας ποιοτικής έρευνας που προσπαθεί να καταγράψει τις αντιλήψεις Λειτουργών Βιβλιοθηκονόμων, σχετικά με την οργάνωση και διοίκηση των σχολικών βιβλιοθηκών της Κύπρου. Ως μέθοδος συλλογής των δεδομένων χρησιμοποιήθηκε η ημιδομημένη συνέντευξη.
Όπως διαφαίνεται από τα συμπεράσματα της μελέτης, η σχολική βιβλιοθήκη πρέπει να συμμετέχει ενεργά σε οποιαδήποτε μακροχρόνια στρατηγική βελτίωσης της εκπαίδευσης, παροχής πληροφόρησης, οικονομικής, κοινωνικής και πολιτιστικής ανάπτυξης. Γι αυτό απαιτείται μια καλοστημένη συλλογή, κατάλληλες εγκαταστάσεις για ανάγνωση και μελέτη, πρόσβαση σε σχετικές τεχνολογίες, εξειδικευμένο προσωπικό καθώς και επαρκή χρηματοδότηση κυρίως από το κράτος . Ακόμη πέρα από το κράτος θα μπορούσε να συνεισφέρει και ένα ίδρυμα ή ένας ιδιώτης. Τέλος, για να εξασφαλιστεί ο συντονισμός των βιβλιοθηκών, πέρα από την υποστήριξη των τοπικών αρχών, πρέπει να υποστηρίζεται με ειδική νομοθεσία και πολιτικές.The library of a contemporary school is its heart and soul. It is a guiding and spiritual center that supports the school syllabus, broadens the students’ learning, helps the teachers in their work and creates the basis for progressive and revolutionary beginnings. All of these are based on the libraries’ variety of materials and the multiple activities that the librarian will be able to develop.
The importance of the school library in the educational process led to the current research. This research intends to present the current state of the school libraries in Cyprus, to contribute to the role that a school library should have nowadays and to show the necessity of employing professional librarians at the school libraries.
This research project presents the results of a qualitative research that attempts to record the ideas of librarians with regards to the organization and management of the school libraries in Cyprus. The data collection was based on semi structured interviews.
Based on the results of this research the school library should participate in an active manner in any long term strategies of improving the educational standards, the education, the availability of information and the financial, social and cultural development. For these to happen it is essential to have a great selection of books, appropriate facilities for reading and studying, access to relative technologies, qualified staff as well as adequate financial help from the state. Apart from the state, both an institution or private organization may contribute to the funding. In addition to assure the coordination of all school libraries both the local authorities and the government through special laws and policies will have to be supportive
Some new bounds on the spectral radius of nonnegative matrices
No full textIn this paper, we determine some new bounds for the spectral radius of a nonnegative matrix with respect to a new defined quantity, which can be considered as an average of average 2-row sums. The new formulas extend previous results using the row sums and the average 2-row sums of a nonnegative matrix. We also characterize the equality cases of the bounds if the matrix is irreducible and we provide illustrative examples comparing with the existing bounds. © 2020 the Author(s)

Changes in the distribution of fitness effects and adaptive mutational spectra following a single first step towards adaptation
No full textAbstractHistorical contingency and diminishing returns epistasis have been typically studied for relatively divergent genotypes and/or over long evolutionary timescales. Here, we use Saccharomyces cerevisiae to study the extent of diminishing returns and the changes in the adaptive mutational spectra following a single first adaptive mutational step. We further evolve three clones that arose under identical conditions from a common ancestor. We follow their evolutionary dynamics by lineage tracking and determine adaptive outcomes using fitness assays and whole genome sequencing. We find that diminishing returns manifests as smaller fitness gains during the 2nd step of adaptation compared to the 1st step, mainly due to a compressed distribution of fitness effects. We also find that the beneficial mutational spectra for the 2nd adaptive step are contingent on the 1st step, as we see both shared and diverging adaptive strategies. Finally, we find that adaptive loss-of-function mutations, such as nonsense and frameshift mutations, are less common in the second step of adaptation than in the first step.</jats:p
Jezus – Ewangelizator [Ὁ Ἰησοῦς] κηρύσσων καὶ εὐαγγελιζόμενος τὴν βασιλείαν τοῦ θεοῦ (Łk 8,1)
No full textThe article is the 19th of the series on Jesus Titles which had been published in „Goœæ Niedzielny” weekly magazine since 1994–1996. The previous ones were a popular presentation of the New Testament Christology whilst the 19s article is a scientifically approached summary of the series. It was specially written for the Commemoration Book dedicated to Petr Pokorný who is professor in biblistics at the Department of Protestant Theology at Charles University in Prague (the Czech Republic) to celebrate his 65th birthday in 1998. As the title Jesus – the Evangelizer has not been used in the Bible (althhough it is used even in the Church’s official documents) the author puts forward the question – Is the title „Jesus Evangelizer” rooted in the Bible and what are its contents? This title has appeared recently with the new evangelization. John Paul II made a postulate in TMA: To discover Jesus Christ again as the only Redeemer of the world. The basis for it is a pericope about a rejection of Jesus Christ in Nazareth (Luke 4,16–30). From the philological point of view basing on BH, LXX and NT the line leeds from the Hebrew term me baœer (RAB:M) throng a Greek substantial form o( eu)aggelizo/menoj (LXX,NT) to the corresponding form evangelizer in medival Latin and the derived from this form neologisms in modern languages, especially in Roman languages up to its presence in Polish theological literature. Polish spelling is „evangelizator” (ewangelizator) but it can not be found in any dictionary of Polish. The author looked for this title in contemporary translations of the Bible and found a term „G³osiciel Ewangelii” (he who preaches the Gospel) as the closest and the most appropriate one.Analysis of the texts in NT where o( eu)aggelizo/menoj refers to Jesus showed topos of the verb eu)aggeli/zein in the New Testament; philological and exegetical analysis of the texts have been carried out and showed evidence that Jesus was in the function of a subject. The word eu)aggeli/zw/eu)aggeli/- zein is present in 55 places in the New Testament and it is also used 9 times in the context which refers to Jesus’s activities: Matt 11,5; Luke 3,14; 4,18; 4,43; 7,22; 8,1; 9,6; 16,16; 20,1. It is used as participium 20 times in the New Testament only in medial and passive form.The author presents the results of his own research and gives the definition: What is the definition of Jesus – Evangelizer? The most accurate and the shortest answer can be found in Luke 8,1 summarium: I)hsou=j diodeu/wn kata\ po/lin kai\ kw/mhn, khru/sswn kai\ eu)aggelizo/menoj th\n basilei/an tou= Qeou= which means Jesus constantly on his way (diodeu/wn) through towns and villages, proclaiming (khru/sswn) Good News about the Kingdom of God which has already come. This is what He was sent for. He himself is the Gospel (Mark 1,1). Basing on the original Greek text it is justfied to use the title I)hsou=j o( eu)aggelizo/menoj (the evangelizing Jesus) which can be translated into Latin used by the Church as Jesus Evangelizans, so the contemporary version of the title is Jesus – the Evangelizer.

Left Atrial Function Post Radiofrequency and Cryoballoon Ablation Assessed by Volume-Pressure Loops
No full textBackground: Left atrial (LA) function is linked to atrial fibrillation (AF) pathogenesis. AF catheter ablation decreases disease burden with potentially favorable effects on cardiac function. Atrial volume-pressure loops can optimally assess the LA function. Objective: To investigate changes in LA function by volume-pressure loops after paroxysmal AF ablation and explored potential differences between the radiofrequency and cryoballoon ablation. Methods: We analyzed 44 patients undergoing paroxysmal AF ablation from 2 centers, 22 treated with radiofrequency and 22 with cryoablation. Pre- and post-procedure, all patients underwent a real-time three-dimensional transthoracic ECG to evaluate LA volume, while simultaneously recording LA pressure following transseptal puncture. Volume-pressure loops pre- and post-procedure were created by paired data. Areas of A-loop (LA booster pump function) and V-loop (LA reservoir function), and the stiffness constant determining the slope of the exponential curve during LA filling were calculated. Results: Average LA pressure, A-wave amplitude, and V-wave amplitude were increased post-procedurally (p < 0.001). Overall, A-loop area decreased (p = 0.001) and V-loop area tended to increase (p = 0.07). The change in both A-loop and V-loop areas was similar between radiofrequency- and cryoballoon-treated patients (p = 0.18 and p = 0.52, respectively). However, compared with cryoballoon-treated patients, radiofrequency-treated patients had higher increase in the stiffness constant (b = 0.059; 95% CI: 0.022–0.096; p = 0.006). Conclusion: AF catheter ablation by the radiofrequency or cryoballoon is associated with the decrease of the booster pump function and increase of the reservoir function. Moreover, there is a post-procedural increase of LA pressure which is associated with an acute increase in LA stiffness in radiofrequency ablation, but not in cryoablation.
