Η εφημερίδα Καθημερινή στη μεταπολίτευση
Authors: Ζαρίκος Ιάσωνας
Published: December 2021

Η παρούσα μελέτη ανατέμνει την ιδεολογική εξέλιξη του ελληνικού φιλελευθερισμού στην Μεταπολίτευση μέσα από την εφημερίδα Η Καθημερινή, από το 1974 ως το 1993. Είναι μια διερώτηση υπό το φως της σταδιακώς συντελεσθείσας ιδεολογικής σύγκλισης στην βάση της ανόθευτης κοινοβουλευτικής δημοκρατίας, της ευρωπαϊκής επιλογής και της αγοραίας οικονομίας ως μοχλού για την ευόδωση της απεριόριστης οικονομικής μεγέθυνσης. Ερειδόμενη στην μέθοδο της ερμηνευτικής παράδοσης, η μελέτη είναι μια ιστορική μελέτη της φιλελεύθερης ιδεολογίας με κύριο αρχείο τα κείμενα της εφημερίδας « Η Καθημερινή», προνομιακού καθρέφτη της εξέλιξης και διαρκούς ανασυγκρότησης της φιλελεύθερης ιδεολογίας στην Μεταπολίτευση.Η μελέτη χωρίζεται σε τρία μέρη. Στο πρώτο μέρος ( 1974-1981 ), η διατριβή παρουσιάζει τις ριζοσπαστικές ιδέες που επεξεργάστηκε η εφημερίδα κατά την πρώτη Μεταπολίτευση, οι οποίες την εγγράφουν στο ρεύμα του «φιλελεύθερου εξισωτισμού» της δεκαετίας του 1970’, με ριζοσπαστικότερη όλων την απόρριψη του ιδανικού της μεγέθυνσης και επιδραστικότερη την άνευ προϋποθέσεων συνάντηση με την ελληνική Αριστερά . Στο δεύτερο μέρος ( 1981-1985), παρουσιάζεται η προσωρινή ευθυγράμμιση της εφημερίδας με την μείζονα Δεξιά και η αναστολή της ιδεολογικής σύγκλισης, αλλά και, αντίρροπα, η απόρριψη του νεοφιλελευθερισμού.Στο τρίτο μέρος ( 1985-1993) με τίτλο « Η Μελαγχολική Δημοκρατία», η μελέτη περιγράφει την βαθμιαία εμπέδωση της σύγκλισης και την διαμόρφωση του αναπτυξιακού φιλελευθερισμού, ιδεολογίας που απέρριψε τόσο την νεοφιλελεύθερη προοπτική όσο και τις ριζοσπαστικές, εξισωτικές ή και αντι-αναπτυξιακές ιδέες που η ίδια η εφημερίδα επεξεργάστηκε στο παρελθόν. Υπόβαθρο της διανοητικής κίνησης των ετών αυτών, αποκαλύπτεται η διαπαραταξιακή εθνική αυτοκριτική, μια πολιτισμική εν τέλει ερμηνεία της κοινωνικής πραγματικότητας. Διεθνή και ελληνικά συμβάντα φωτίζονται υπό αυτό το πρίσμα και παράλληλα αναδεικνύεται η διαρκής επικαιρότητα του εθνικισμού. Στο τέλος της μελέτης, η εφημερίδα και οι άνθρωποί της μετέχουν μιας σαρωτικής απογοήτευσης από την πολιτική, τους εκπροσώπους της και από τις ιδεολογίες.Η Μελαγχολική Δημοκρατία επικρατεί και η εποχή της συναισθηματικής αποκοπής από τις ιδεολογίες αρχίζει.Ήδη από την εισαγωγή έχει γίνει θεωρητική κριτική στην έννοια του «λαϊκισμού», κριτική που εξακολουθεί σε όλο το μάκρος της μελέτης και καταδεικνύει την ανεπάρκεια της έννοιας από την άποψη της διανοητικής Ιστορίας

Published: December 2021

Στη διατριβή μας αναλύουμε την έννοια της πολιτικής πρακτικής μέσα από την πολιτική σκέψη και την φαινομενολογία του φιλοσόφου Μaurice Merleau-Ponty. Στο πρώτος μέρος αναλύουμε έννοιες της πολιτικής θεωρίας μέσα από τα πολιτικό-φιλοσοφικά κείμενα του φιλοσόφου. Στο δεύτερο μέρος προσπαθούμε να συγκροτήσουμε μια φαινομενολογία του πολιτικού μέσω της φαινομενολογίας της γλώσσας, της έκφρασης και της θέσπισης στο φαινομενολογικό έργο του Μaurice Merleau-Ponty.

Published: December 2021

Η παρούσα διατριβή παρουσιάζει τα αποτελέσματα μιας ποιοτικής έρευνας σε μελλοντικούς εκπαιδευτικούς στην Ελλάδα. H μελέτη διερευνά τους τρόπους με τους οποίους οι μελλοντικοί εκπαιδευτικοί χρησιμοποιούν τα μέσα κοινωνικής δικτύωσης για ακαδημαϊκούς σκοπούς με δική τους πρωτοβουλία. Χρησιμοποιήθηκαν διαφορετικές μέθοδοι συλλογής δεδομένων, με τις ημιδομημένες συνεντεύξεις να αποτελούν την κύρια μέθοδο. Τα πλούσια δεδομένα που συλλέχθηκαν από 36 μελλοντικούς εκπαιδευτικούς ανέδειξαν μια περίπλοκη εικόνα αναφορικά με τη χρήση των μέσων κοινωνικής δικτύωσης. Τα αποτελέσματα δείχνουν ότι οι συμμετέχοντες χρησιμοποίησαν μια σειρά από μέσα κοινωνικής δικτύωσης για να ανταποκριθούν στις απαιτήσεις των σπουδών τους στην εκπαίδευση εκπαιδευτικών και να αναπτύξουν τη φοιτητική τους ταυτότητα. Παράλληλα, χρησιμοποίησαν τα μέσα κοινωνικής δικτύωσης για να προετοιμαστούν για τη μετάβασή τους στο μελλοντικό τους επάγγελμα. Μέσω των μέσων κοινωνικής δικτύωσης, οι συμμετέχοντες ασχολήθηκαν με τη δημιουργία κοινωνικού κεφαλαίου στα ήδη υπάρχοντα δίκτυά τους, όπως και σε ευρύτερα σύνολα ατόμων που αποτελούνταν από συνομηλίκους και μελλοντικούς συναδέλφους τους. Η μελέτη εξετάζει τα οφέλη που προκύπτουν από τη συγκεκριμένη χρήση των μέσων κοινωνικής δικτύωσης. Επιπλέον, τονίζεται η σημασία της μη ενεργητικής συμμετοχής και της δημιουργίας δυνητικών δεσμών. Τέλος, η διατριβή παρουσιάζει ένα πλαίσιο που στοχεύει να συνδέσει τις βασικές έννοιες πάνω στις οποίες βασίστηκε η έρευνα, τόσο απαγωγικά όσο και επαγωγικά. Αυτό αποτελεί τη συμβολή μου στη γνώση. Υπογραμμίζεται η σημασία της αναγνώρισης των επικαλυπτόμενων ορίων μεταξύ προσωπικών και ακαδημαϊκών σκοπών για την κατανόηση της χρήσης των μέσων κοινωνικής δικτύωσης, όπως και της αναγνώρισης της περίπλοκης πραγματικότητας των συμμετεχόντων. Η έρευνα συμβάλλει στην υπάρχουσα βιβλιογραφία παρέχοντας σε βάθος ποιοτικά δεδομένα σχετικά με τους τρόπους με τους οποίους οι συμμετέχοντες επέλεξαν να χρησιμοποιήσουν τα μέσα κοινωνικής δικτύωσης για σκοπούς που σχετίζονται τόσο με τις σπουδές τους όσο και με το επάγγελμά τους. Με βάση τα αποτελέσματα, η διατριβή παρουσιάζει θεωρητικές και πρακτικές συνέπειες για τα ιδρύματα αρχικής εκπαίδευσης εκπαιδευτικών, καθώς και προτάσεις για μελλοντικές έρευνες σχετικά με τη χρήση των μέσων κοινωνικής δικτύωσης από μελλοντικούς εκπαιδευτικούς.
Battery emulator operating in a power hardware-in-the-loop simulation
Authors: Δανιήλ Νικόλαος
Published: December 2021

Στην παρούσα διατριβή παρουσιάζεται ο σχεδιασμός και η υλοποίηση ενός Εξομοιωτή Μπαταριών (Battery Emulator - BE) που λειτουργεί σε Περιβάλλον Προσομοίωσης Ισχύος (Power Hardware-in-the-Loop Simulation – PHIL) και εισάγεται η ιδέα του Υβριδικού Εξομοιωτή Μπαταριών (Hybrid Battery Emulator – ΗΒΕ). Η έρευνα επικεντρώθηκε σε τρεις κύριους τομείς: μοντελοποίηση μπαταρίας, αλγόριθμοι παρακολούθησης μπαταρίας και διεπαφή ισχύος της συσκευής που υλοποιεί τον εξομοιωτή. Τα ευρήματα από όλους τους ανωτέρω τομείς συνδυάζονται στον Υβριδικό Εξομοιωτή Μπαταριών (HBE).Εφαρμόζονται και συγκρίνονται τρία μοντέλα μπαταριών: το Ισοδύναμο Κύκλωμα (Equivalent Circuit Model - ECM), το Κινητικό (Kinetic Battery Model - KiBaM) και η Διάχυση (Diffusion). Η σύγκριση δείχνει ότι το μοντέλο Διάχυσης απαιτεί πολύ υψηλότερη υπολογιστική ισχύς και επομένως, είναι λιγότερο κατάλληλο για εφαρμογή σε πραγματικό χρόνο. Όσον αφορά τα άλλα δύο, το KiBaM είναι πιο απλό στην παραμετροποίηση, αλλά το ECM παρουσιάζει μεγαλύτερη ακρίβεια κατά την προσομοίωση. Η ανάλυση ευαισθησίας που πραγματοποιήθηκε, αποκαλύπτει ότι η πιο σημαντική παράμετρος για την ακρίβεια της προσομοίωσης είναι το Επίπεδο Φόρτισης (State of Charge - SoC). Η μέθοδος που προτείνεται για την αύξηση της ακρίβειας του Επίπεδου Φόρτισης (SoC) είναι ένας Παρατηρητής Λειτουργίας με την μέθοδο της Ολίσθησης (Sliding Mode Observer), ο οποίος συγκρίνει τη μετρούμενη τάση από μια πραγματική κυψέλη με την τάση που υπολογίζεται από το μοντέλο της μπαταρίας και προσαρμόζει το Επίπεδο Φόρτισης (SoC) αναλόγως.Για την επίδειξη των δυνατοτήτων αυτής της εφαρμογής, χρησιμοποιείται κοινό τροφοδοτικό του εμπορίου το οποίο υλοποιεί την Εξομοιωτή Μπαταριών (ΒΕ). Από την ανάλυση ευστάθειας που πραγματοποιήθηκε, προκύπτει η ανάγκη σύνδεσης μιας αντίσταση σε σειρά με την έξοδο του τροφοδοτικού καθώς και το αποδεκτό εύρος τιμών της υπόψη αντίστασης. Παρουσιάζονται δύο υλοποιήσεις του Υβριδικού Εξομοιωτή Μπαταριών (HBE). Και στις δύο υλοποιήσεις, ένα μόνο κελί από τη συστοιχία της μπαταρίας είναι συνδεδεμένο σε σειρά με τη συσκευή η οποία εξομοιώνει τα υπόλοιπα κελιά. Κατά την πρώτη υλοποίηση, ένα μοντέλο μπαταρίας παρέχει την τάση αναφοράς στο τροφοδοτικό που υλοποιεί τον εξομοιωτή και οι μετρήσεις από το εν σειρά συνδεδεμένο κελί χρησιμοποιούνται για την ενημέρωση των παραμέτρων του μοντέλου. Τα πειράματα αποκαλύπτουν ότι τα σφάλματα στο Επίπεδο Φόρτισης (SoC) μειώνονται και ότι η ακρίβεια εξομοίωσης αυξάνεται σημαντικά. Στη δεύτερη μέθοδο, δεν υπάρχει μοντέλο μπαταρίας. Η πραγματική τάση του εν σειρά συνδεδεμένου κελιού μετράται, πολλαπλασιάζεται και ορίζεται ως αναφορά στο τροφοδοτικό που υλοποιεί τον εξομοιωτή. Αυτή η υλοποίηση παρουσιάζει μεγαλύτερη ακρίβεια αλλά δεν προτείνεται γιατί δεν παρέχει πληροφορίες για την κατάσταση της μπαταρίας. Τέλος, προτείνεται ως μελλοντική εργασία μια εναλλακτική υλοποίηση Υβριδικού Εξομοιωτή Μπαταριών (HBE), στην οποία ένα κελί από τη συστοιχία της μπαταρίας λειτουργεί σε ένα παράλληλο πείραμα με μειωμένο ρεύμα.
Writing tool transitions and symbioses of pre-digital creative educators in Greece
Authors: Καραβανίδου Ελένη
Published: December 2021

Η παρούσα διατριβή είναι πολλαπλή μελέτη περίπτωσης με θέμα τους ενσώματους τρόπους γραφής, τις αναμνήσεις και τις μελλοντικές προσδοκίες περί γραφής τεσσάρων Ελληνίδων εκπαιδευτικών. Διερευνήθηκε ο τρόπος που τα μέλη της έρευνας υιοθέτησαν νέα μέσα γραφής ως ενήλικοι και το πώς εναλλάσσονται μεταξύ αναλογικής και ψηφιακής γραφής. Η μοναδικής ιστορικής σημασίας μετάβαση της γραφής από αναλογική σε ψηφιακή βρίσκει την προσωποποίησή της στα άτομα που μεγάλωσαν γράφοντας με αναλογικά μέσα και που βίωσαν μια μεγάλη και ραγδαία αλλαγή στο γράψιμο. Στα πλαίσια της ενσώματης μάθησης (embodied cognition) και χρησιμοποιώντας το επιλεκτικό θεωρητικό μοντέλο (piecemeal theorising) ερευνήθηκε πώς οι μεταβάσεις και ο συμβιωτικός χαρακτήρας των παλιών και νέων μέσων επηρεάζουν την αναγκαιότητα που νιώθουν τα μέλη να γράφουν δημιουργικά. Οι ποικίλες μέθοδοι διερεύνησης του φαινομένου υπαγορεύτηκαν από την πολυπλοκότητά του⸱ συνεντεύξεις, βιντεοσκοπήσεις, φωτογραφήσεις, παρατήρηση και ανίχνευση προσωπικών χειρόγραφων πριν και μετά το πέρασμα στον υπολογιστή είχαν στόχο την κατανόηση εις βάθος των ιστορικών, κοινωνικών και προσωπικών παραμέτρων που συνυφαίνονται στο φαινόμενο. Οι αναδυόμενες ανάγκες της έρευνας οδήγησαν την όψιμη συμπερίληψη της ίδιας της ερευνήτριας ως πέμπτη περίπτωση, εμπλουτίζοντας με αυτοεθνογραφικά μεθοδολογικά εργαλεία τη διαβάθμιση του δείγματος και καλύπτοντας κενά που ανέκυψαν. Τα αποτελέσματα της έρευνας επιβεβαιώνουν την κοινωνική και πολιτιστική πλευρά της Θεωρίας των Μέσων: ότι το προψηφιακό δημιουργικό άτομο είναι ενεργητικός όχι παθητικός δέκτης των νέων τεχνολογιών. Η μετάβαση των μελών σε νέα εργαλεία γραφής εξετάζεται και εκφράζεται με όρους της Βιολογίας («συμβίωση», «ουδετερότητα» και «παρασιτισμός») υποδεικνύοντας μια αργή τάση προς την επικράτηση του πληκτρολογίου εις βάρος του χειρόγραφου. Προτάσεις για μελλοντική έρευνα αφορούν τον επαναπροσδιορισμό της εικαστικής και ερμηνευτικής φύσης της γραφής με το χέρι καθώς και μικτές παιδαγωγικές πρακτικές στη γραφή.

The concept of the unconscious in the early cognitive therapy of Aaron T. Beck
Authors: Romanowska Monika , Dobroczyński Bartłomiej
Published: December 2021

Standardowa narracja na temat narodzin terapii poznawczej głosi, że jej twórca Aaron T. Beck zerwał wszelkie więzi z psychoanalizą i wybrał drogę formułowania teorii opartą na eksperymentach naukowych. Wydaje się jednak, że podejście Becka do roli i znaczenia utajonych procesów poznawczych było o wiele bardziej złożone. Celem artykułu jest przybliżenie czytelnikom aktualnych badań historycznych na temat narodzin terapii poznawczej oraz przedstawienie beckowskiego ujęcia procesów nieświadomych we wczesnej wersji jego teorii, ze szczególnym naciskiem na drogę dojścia do nieświadomych treści. Sugerujemy, że na kształt wczesnej teorii miały wpływ ówczesna sytuacja w amerykańskiej opiece psychiatrycznej, retoryka związana z Zimną Wojną oraz psychoanalityczne wykształcenie Aarona T. Becka. W swoich wczesnych pracach Beck nie rozwinął wystarczająco pojęcia „schematu”, co pozostawiło lukę w jego teorii. Zauważamy także, że Beck nie opisywał w owym czasie szerzej dedukcyjnej drogi dotarcia do treści nieświadomych. Uzyskane wnioski umożliwiają terapeutom lepsze zrozumienie źródeł terapii poznawczej oraz trudności, z jakimi zmagał się Beck.
Patients with eating disorders in the time of COVID-19
Authors: Sikora Dorota
Published: December 2021

Artykuł prezentuje problematykę funkcjonowania psychicznego osób z zaburzeniami odżywiania w czasie pandemii COVID-19, odnosząc się do wybranych badań zagranicznych, w których badacze poszukują danych na temat czynników ryzyka zaburzeń odżywiania w okresie pandemii. COVID-19 szybko rozprzestrzenił się na świecie, wymuszając na ludności podjęcie natychmiastowych działań i zmianę stylu życia. W życiu społecznym zaszły diametralne zmiany, na które społeczeństwo nie było gotowe. Izolacja i konieczność zachowania dystansu społecznego ograniczyły dostęp do opieki zdrowotnej, co miało znaczący wpływ na funkcjonowanie psychiczne osób z zaburzeniami psychicznymi, w tym osób z zaburzeniami odżywiania. Na świecie podejmuje się liczne badania celem określenia tego wpływu, a dotychczasowe wyniki wskazują na pogorszenie funkcjonowania osób z zaburzeniami odżywiania. Terapeuci i klinicyści poszukują możliwości wdrożenia modyfikacji w programie leczenia, by jak najlepiej dostosować go do obostrzeń, ale też potrzeb i celów pacjenta. W okresie lockdownu zalecano korzystanie ze zdalnej formy spotkań, jednak nie każdy pacjent i terapeuta/lekarz był w stanie się w niej odnaleźć, w wyniku czego część pacjentów pozostała bez specjalistycznej opieki. Skutkiem był wzrost ryzyka całkowitej rezygnacji z leczenia lub jego nieregularność, a w efekcie pogorszenie funkcjonowania psychicznego pacjentów.
Quality 4.0 for Processes and Customers
Authors: Efimova Anastasia , Briš Petr
Published: December 2021

Purpose: Considering the speed of technological development towards the Industry 4.0 era the change is necessary for managerial aspects in industrial companies. In this paper an attempt is made to understand the influence of Industry 4.0 technologies on the Quality 4.0 concept better.     
Methodology/Approach: Two aspects were analysed in order to achieve the goal – the influence of Industry 4.0 on quality management and the influence of Quality 4.0 on customer satisfaction. The paper is based on a literature review and a pilot study based on questionnaires prepared for research purposes.
Findings: It was found out that the emergence of new technologies is beneficial for Quality Management processes and customer satisfaction. Moreover, the influence is greatly described by the amount of data now available for analysis. However, as the concept of Quality 4.0 is in its infancy, the necessary change is still required.
Research Limitation/Implication: As the research was conducted in the Czech Republic, the results are limited according to the territory. Also, the study was based on the literature review available from SCOPUS and WoS databases in English, thus further studies of available literature in other languages might be needed.
Originality/Value of paper: Although the quality tools that are used in Quality 4.0 are already known and accepted the influence of advanced technologies on quality management is not clear. In this paper an attempt is made to understand the influence.

Authors: Palfy Pavol , Marenčíková Barbora
Published: December 2021

Purpose: The objective of the study was to analyse and evaluate two alternative liquid detergent packaging systems from the point of view of their overall environmental impact. Using the LCA method, we have come to the conclusion that cardboard packaging is an alternative with a lower negative impact on the environment than an HDPE bottle.        
Methodology/Approach: The study is based on the LCA method implemented through the software openLCA, including available databases.
Findings: The environmentally friendlier alternative of the detergent packaging is identified. The decisions about individual stages during LCA must be made with caution and well documented to ensure credibility of the results.
Research Limitation/Implication: The findings of the presented study are limited by the available data used for the environmental impact assessment. The inventory analysis was performed for the conditions of the central European region.
Originality/Value of paper: This study applies LCA methodology to present the details of a decision process involved in selecting better environmental alternative of the product. The information generated by the study is directly applicable in the industry.
UNA DESCOMPOSICIÓN GENÉTICA PRELIMINAR DEL CONCEPTO DE EIGENVALOR Y EIGENVECTOR: EL ANÁLISIS DE LIBROS DE TEXTO COMO SUSTRATO EN LA CONSTRUCCIÓN DE MODELOS COGNITIVOS
Authors: Betancur Sánchez Alexander , Roa Fuentes Solange , Ballesteros Silvia Juliana
Published: December 2021

En la teoría APOE (Acción, Proceso, Objeto, Esquema) el diseño de una descomposición genética es resultado del Análisis Teórico (primer componente del ciclo de investigación de la teoría) donde el análisis de libros de texto es uno de los elementos a considerar. Sin embargo, a la fecha de este reporte no se encuentran publicaciones que den cuenta de cómo realizar el análisis de libros de texto y el proceso detrás de la construcción de una descomposición genética. En este escrito se usan los criterios propuestos por Campos (2017) para analizar tres libros de texto de álgebra lineal, específicamente en relación al concepto de eigenvalor y eigenvector junto con una metodología que da cuenta del diseño de una descomposición genética preliminar para el concepto de eigenvalor y eigenvector sobre operadores lineales considerando: el insumo del análisis de libros de texto, los reportes de investigación existentes y la experiencia de los investigadores como profesores y estudiantes.

Authors: Jain Esha , Al-Tarbsheh Ali Hani , Oweis Jozef , Jacobson Erik , Shkolnik Boris
Published: December 2021

Hodgkin Lymphoma (HL) typically presents similarly to an infectious etiology, thus awareness of its atypical presentations is essential. We present a case of an adult woman who was found to have HL after presenting with a dry, non-productive cough and showing cavitary lesions on chest computed tomography (CT). We also describe the clinical, laboratory, and radiological workup done leading to the diagnosis and management of HL in a critical care setting.
Gender Paradox and Women’s Spatiality: A Case Study of “Mothers Accompanying Children in Education” at the Chiang Mai Chinese Christian Church
Authors:   Faculty of Social Sciences, Chiang Mai University, Chiang Mai 50200, Thailand, Lan Xiaoxia , Siriphon Aranya ,   Faculty of Social Sciences, Chiang Mai University, Chiang Mai 50200, Thailand
Published: December 2021

This article explores a group of new Chinese migrant “peidu mamas” or “mothers accompanying children in education” in the Chiang Mai city, Thailand. By using ethnography as the research methodology, this article examines the gender role and women’s spatiality issues that exist between the church and the community. After interviewing informants and doing participation observation at Chiang Mai Huaren Jidu Church for several months, the researchers unravel how the “peidu mamas” in the church have faced an extreme level of gender paradox and gender hierarchy while participating in the church activities. These “peidu mamas” strategically utilize Christian interpretation by deploying the traditional Chinese concept with regards to “obedience” and “reserved patriarchal bargaining.” It is an attempt to reduce the inferior status encountered by the female Chinese Christian “peidu mamas” and to negotiate the paradoxical Confucianism beliefs regarding gender hierarchy and family values. Keywords: Gender paradox, Patriarchal bargain, Spatiality
What are the best diagnostic tests for diagnosing bacterial arthritis of a native joint?
Authors: Walinga Alex B. , Stornebrink Tobias , Langerhuizen David W. G. , Struijs Peter A. A. , Kerkhoffs Gino M. M. J. , Janssen Stein. J.
Published: December 2021

Aims

This study aimed to answer two questions: what are the best diagnostic methods for diagnosing bacterial arthritis of a native joint?; and what are the most commonly used definitions for bacterial arthritis of a native joint?

Methods

We performed a search of PubMed, Embase, and Cochrane libraries for relevant studies published between January 1980 and April 2020. Of 3,209 identified studies, we included 27 after full screening. Sensitivity, specificity, area under the curve, and Youden index of diagnostic tests were extracted from included studies. We grouped test characteristics per diagnostic modality. We extracted the definitions used to establish a definitive diagnosis of bacterial arthritis of a native joint per study.

Results

Overall, 28 unique diagnostic tests for diagnosing bacterial arthritis of a native joint were identified. The following five tests were deemed most useful: serum ESR (sensitivity: 34% to 100%, specificity: 23% to 93%), serum CRP (sensitivity: 58% to 100%, specificity: 0% to 96%), serum procalcitonin (sensitivity: 0% to 100%, specificity: 68% to 100%), the proportion of synovial polymorphonuclear cells (sensitivity: 42% to 100%, specificity: 54% to 94%), and the gram stain of synovial fluid (sensitivity: 27% to 81%, specificity: 99% to 100%).

Conclusion

Diagnostic methods with relatively high sensitivities, such as serum CRP, ESR, and synovial polymorphonuclear cells, are useful for screening. Diagnostic methods with a relatively high specificity, such as serum procalcitonin and synovial fluid gram stain, are useful for establishing a diagnosis of bacterial arthritis. This review helps to interpret the value of various diagnostic tests for diagnosing bacterial arthritis of a native joint in clinical practice.

Sunset in the West: outsourcing editorial work from the UK to India - a case study of the impact on workers
Authors: Simone Dahlmann  , Ursula Huws
Published: December 2021

This paper presents a case study carried out in a large academic publishing and printing house. Interviews were carried out in both locations with senior and middle management, workers and trade unionsto gain their perspectives on the outsourcing of typesetting and editorial work from the UK to India. In Britain, ‘working in publishing’ traditionally represented a prestigious and highly sought-after career for graduates with high skills, both generic and occupation-specific. This paper explores the shock experienced by these workers when faced with the prospect of losing their jobs to the Indian labour market and argues that the outsourcing of skilled work in an increasingly globalised labour market introduces new forms of precariousness even to highly qualified workers with diverse skills. However the study also finds that the workers in India who are taking over these tasks are not experiencing the benefits previously enjoyed by their British counterparts. On the contrary, on the evidence of this case study, their jobs too are highly insecure. It concludes that the qualitative effects of offshore outsourcing on employment are more important than quantitative impacts.
Immaterial Fordism: the paradox of game industry labour
Authors: Leif Schumacher
Published: December 2021

In different ways, Marxist autonomist, regulation school, and neoliberal theories all claim that work in the new economy is increasingly characterised by high levels of creativity, cooperation, and innovation, albeit accompanied by uncertainty and a relentless pace of work, introducing a new form of labour that differs fundamentally from past forms. This paper does not disagree with the proposition that capital is currently in the process of intensifying its search for more efficient value extraction. However, through a case study of lawsuits launched against the video game company Electronic Arts regarding its labour practices, it argues that the change in the nature of knowledge work and immaterial labour has been overstated by the adherents of these three schools and that what we are witnessing is not so much a replacement of traditional Fordist practices by post-Fordist ones as a new fusion of the two forms.
CATCHING A BUTTERFLY? Mapping eWork in Europe and Australia
Authors: Peter Standen
Published: December 2021

Drawing on the results of surveys carried out by the EMERGENCE project in 18 European countries in 2000 and Australia in 2002, this paper gives an overview of the relocation of telemediated work in Europe and Australia, highlighting the persistence of traditional regional and national locational patterns. It concludes by reflecting on some of the implications of the new possibilities for the relocation of telemediated work for regional policy.
Workers' knowledge in the ‘knowledge society’: voices from the South
Authors: Sujata Gothoskar
Published: December 2021

Drawing on first-hand interviews with call centre workers in Mumbai, participant observation and a variety of secondary sources, including email forum contributions by call centre workers, this paper takes a critical look at the concept of the ‘knowledge economy’ from the perspective of those who work in it. In particular, it questions the extent to which ‘knowledge workers’ have access to the knowledge that underlies the work that they do and points to the ways in which this knowledge is eroded as value chains are extended. It also looks at these workers’ stakes in their skills and work, and concludes by pointing to a series of contradictions that are raised for Indian society by the rapid development of the knowledge economy there.

The distribution of variably present genetic markers [Burkholderiaintracellular motility A (bimA)gene variantsbimABP/bimABM, filamentous hemagglutinin 3 (fhaB3),Yersinia-like fimbrial (YLF) andB.thailandensis-like flagellum and chemotaxis (BTFC) gene clusters and lipopolysaccharide O-antigen type A (LPS type A)] was examined among 310 strains. Multilocus sequence typing (MLST) was done for 84 clinical isolates. The phylogenetic and evolutionary relationship of Sri Lankan STs within Sri Lanka and in relation to those found in other endemic regions of Southeast Asia and Oceania were studied using e BURST, PHYLOViZ and minimum evolutionary analysis.

Results

The Sri LankanB.pseudomalleipopulation contained a large proportion of the rare BTFC clade (14.5%) andbimABMallele variant (18.5%) with differential geographic distribution. GenotypesfhaB3 andLPSA were found in 80% and 86% respectively. This study reported 43 STs (including 22 novel). e-BURST analysis which include all Sri Lankan STs (71) resulted in four groups, with a large clonal group (group 1) having 46 STs, and 17 singletons. ST1137 was the commonest ST. Several STs were shared with India, Bangladesh and Cambodia.

Conclusion

This study demonstrates the usefulness of high-resolution molecular typing to locate isolates within the broad geographical boundaries ofB.pseudomalleiat a global level and reveals that Sri Lankan isolates are intermediate between Southeast Asia and Oceania.

Introduction

Chikungunya virus (CHIKV) is a mosquito-borne virus known to cause acute febrile illness associated with debilitating polyarthritis. In 2019, several institutions in Myanmar reported a CHIKV outbreak. There are no official reports of CHIKV cases between 2011 and 2018. Therefore, this study sought to determine the seroprevalence of CHIKV infection before the 2019 outbreak.

Methods

A total of 1,544 serum samples were collected from healthy volunteers and patients with febrile illnesses in Yangon, Mandalay, and the Myeik district in 2013, 2015, and 2018. Participants ranged from one month to 65 years of age. Antibody screening was performed with in-house anti-CHIKV IgG and IgM ELISA. A neutralization assay was used as a confirmatory test.

Results

The seroprevalence of anti-CHIKV IgM and anti-CHIKV IgG was 8.9% and 28.6%, respectively, with an overall seropositivity rate of 34.5%. A focus reduction neutralization assay confirmed 32.5% seroprevalence of CHIKV in the study population. Age, health status, and region were significantly associated with neutralizing antibodies (NAbs) and CHIKV seropositivity (p < 0.05), while gender was not (p = 0.9). Seroprevalence in 2013, 2015, and 2018 was 32.1%, 28.8%, and 37.3%, respectively. Of the clinical symptoms observed in participants with fevers, arthralgia was mainly noted in CHIKV-seropositive patients.

Conclusion

The findings in this study reveal the circulation of CHIKV in Myanmar’s Mandalay, Yangon, and Myeik regions before the 2019 CHIKV outbreak. As no treatment or vaccine for CHIKV exists, the virus must be monitored through systematic surveillance in Myanmar.

In 2019, the World Health Organization declared 3 billion to be at risk of developing Crimean Congo Hemorrhagic Fever (CCHF). The causative agent of this deadly infection is CCHFV. The data related to the biology and immunology of CCHFV are rather scarce. Due to its indispensable roles in the viral life cycle, NP becomes a logical target for detailed viral immunology studies. In this study, humoral immunity to NP was investigated in CCHF survivors, as well as in immunized mice and rabbits. Abundant antibody response against NP was demonstrated both during natural infection in humans and following experimental immunizations in mice and rabbits. Also, cellular immune responses to recombinant NP (rNP) was detected in multispecies. This study represents the most comprehensive investigation on NP as an inducer of both humoral and cellular immunity in multiple hosts and proves that rNP is an excellent candidate warranting further immunological studies specifically on vaccine investigations.

Published: December 2021

The situation of human rabies in Thailand has gradually declined over the past four decades. However, the number of animal rabies cases has slightly increased in the last ten years. This study thus aimed to describe the characteristics of animal rabies between 2017 and 2018 in Thailand in which the prevalence was fairly high and to quantify the association between monthly rabies occurrences and explainable variables using the generalized additive models (GAMs) to predict the spatial risk areas for rabies spread. Our results indicate that the majority of animals affected by rabies in Thailand are dogs. Most of the affected dogs were owned, free or semi-free roaming, and unvaccinated. Clusters of rabies were highly distributed in the northeast, followed by the central and the south of the country. Temporally, the number of cases gradually increased after June and reached a peak in January. Based on our spatial models, human and cattle population density as well as the spatio-temporal history of rabies occurrences, and the distances from the cases to the secondary roads and country borders are identified as the risk factors. Our predictive maps are applicable for strengthening the surveillance system in high-risk areas. Nevertheless, the identified risk factors should be rigorously considered and integrated into the strategic plans for the prevention and control of animal rabies in Thailand.
Effects of health education on adolescents’ non-cognitive skills, life satisfaction and aspirations, and health-related quality of life: A cluster-randomized controlled trial in Vietnam

Published: December 2021

Objective

The effectiveness of health education on adolescents has been questioned, along with a growing body of empirical studies documenting the absence of behavioral changes after the intervention. However, evidence on its impact on other crucial health domains, besides health practices, is lacking. We evaluated the causal effects of a school-based health education program on adolescents’ multidimensional psychological health factors.

Design

A cluster-randomized controlled trial.

Methods

We conducted a cluster-randomized controlled trial involving 140 lower secondary schools in Vietnam. After stratifying by district, schools were randomized 1:1 to either treatment or control groups. Students enrolled in the treatment schools received monthly stand-alone health education in five topics by school teachers at the class level, but control group students did not receive any intervention. The primary outcomes of the study were students’ non-cognitive skills, life satisfaction, aspirations gap, and the Health-Related Quality of Life at five-month follow-up. We estimated the intention-to-treat effects with the panel fixed effects model using student panel data.

Results

Of the 6,477 students enrolled at baseline, 2,958 (92%) treated and 2,967 (91%) control students completed the follow-up survey five months after baseline data collection from October to December 2018. Compared with controls, health education led to improved treatment school students’ self-efficacy (p-value = 0.013), presumed life satisfaction five years from the present (p-value = 0.001), aspirations gap for a socially and mentally healthy future (p-value = 0.036), and the Health-Related Quality of Life (p-value = 0.036).

Conclusion

A school-based health education program enhanced students’ non-cognitive skills, life satisfaction and aspirations gap, and the Health-Related Quality of Life significantly. This study proposes essential psychological factors that should be taken into account when evaluating the effectiveness of a health education program in resource-limited settings.
The effects of malapportionment on economic development
Authors: Bhavnani Rikhil R.
Published: December 2021

Does the unequal formal representation of people in legislatures (“malapportionment”) affect development? Answering this question is critical for assessing the welfare costs of malapportionment. We argue that representation might spur development as the desire for reelection incentivizes legislators to provide for their districts, and as voters hold politicians to account for doing so. Since this is the case, malapportionment might cause unequal development. Using data from India, we show that a 10% increase in representation causes a 0.6% increase in night lights, a frequently used proxy for development. Reapportionment, or the equalization for representation, attenuates this effect. Consistent with the theory, the effect of representation is larger in districts with legislators and voters that are able to hold the executive to account.

Published: December 2021

The recent uptake in popularity in vehicles with zero tailpipe emissions is a welcome development in the fight against traffic induced airborne pollutants. As vehicle fleets become electrified, and tailpipe emissions become less prevalent, non-tailpipe emissions (from tires and brake disks) will become the dominant source of traffic related emissions, and will in all likelihood become a major concern for human health. This trend is likely to be exacerbated by the heavier weight of electric vehicles, their increased power, and their increased torque capabilities, when compared with traditional vehicles. While the problem of emissions from tire wear is well-known, issues around the process of tire abrasion, its impact on the environment, and modelling and mitigation measures, remain relatively unexplored. Work on this topic has proceeded in several discrete directions including: on-vehicle collection methods; vehicle tire-wear abatement algorithms and controlling the ride characteristics of a vehicle, all with a view to abating tire emissions. Additional approaches include access control mechanisms to manage aggregate tire emissions in a geofenced area with other notable work focussing on understanding the particle size distribution of tire generated PM, the degree to which particles become airborne, and the health impacts of tire emissions. While such efforts are already underway, the problem of developing models to predict the aggregate picture of a network of vehicles at the scale of a city, has yet to be considered. Our objective in this paper is to present one such model, built using ideas from Markov chains. Applications of our modelling approach are given toward the end of this note, both to illustrate the utility of the proposed method, and to illustrate its application as part of a method to collect tire dust particles.

The heterogeneous presentation of inattentive and hyperactive-impulsive core symptoms in attention deficit hyperactivity disorder (ADHD) warrants further investigation into brain network connectivity as a basis for subtype divisions in this prevalent disorder. With diffusion and resting-state functional magnetic resonance imaging data from the Healthy Brain Network database, we analyzed both structural and functional network efficiency and structure-functional network (SC-FC) coupling at the default mode (DMN), executive control (ECN), and salience (SAN) intrinsic networks in 201 children diagnosed with the inattentive subtype (ADHD-I), the combined subtype (ADHD-C), and typically developing children (TDC) to characterize ADHD symptoms relative to TDC and to test differences between ADHD subtypes. Relative to TDC, children with ADHD had lower structural connectivity and network efficiency in the DMN, without significant group differences in functional networks. Children with ADHD-C had higher SC-FC coupling, a finding consistent with diminished cognitive flexibility, for all subnetworks compared to TDC. The ADHD-C group also demonstrated increased SC-FC coupling in the DMN compared to the ADHD-I group. The correlation between SC-FC coupling and hyperactivity scores was negative in the ADHD-I, but not in the ADHD-C group. The current study suggests that ADHD-C and ADHD-I may differ with respect to their underlying neuronal connectivity and that the added dimensionality of hyperactivity may not explain this distinction.

Skin inflammation leads to altered cytokine/chemokine production and causes systemic inflammation. The systemic mechanism of atopic dermatitis (AD) is recognized to affect systemic metabolism. This study aimed to examine the relationship between early-onset persistent eczema and body weight, height, and body mass index (BMI), in addition to food allergy in a birth cohort among infants. This study design was a nationwide, multicenter, prospective birth cohort study—the Japan Environment and Children’s Study (JECS). Generalized linear models were fitted for z scores of weight, height, BMI, and food allergy to evaluate the relationship between eczema and these outcomes for infants at age1, 2, and 3 years. Persistent eczema was negatively associated with height at the age of 2 years (estimated coefficient, −0.127; 95% confidence interval [CI], −0.16 to −0.095) and 3 years (−0.177; 95% CI, −0.214 to −0.139). The same tendency was also observed with weight and BMI. Early disease onset at younger than 1 year and persistent eczema had the strongest association with development of food allergy at age 3 years (OR, 11.794; 95% CI, 10.721–12.975). One phenotype of eczema with early-onset and persistent disease creates a risk of both physical growth impairment and development of food allergy. Infants who present with the early-onset and persistent type of eczema should be carefully evaluated daily for impaired physical growth and development of food allergy.

Published: December 2021

Objective

The demand for treating degenerative lumbar spinal disease has been increasing, leading to increased utilization of medical resources. Thus, we need to understand how the budget of insurance is currently used. The objective of the present study is to overview the utilization of the National Health Insurance Service (NHIS) by providing the direct insured cost between patients receiving surgery and patients receiving nonsurgical treatment for degenerative lumbar disease.

Methods

The NHIS-National Sample Cohort was utilized to select patients with lumbar disc herniation, spinal stenosis, spondylolisthesis or spondylolysis. A matched cohort study design was used to show direct medical costs of surgery (n = 2,698) and nonsurgical (n = 2,698) cohorts. Non-surgical treatment included medication, physiotherapy, injection, and chiropractic. The monthly costs of the surgery cohort and nonsurgical cohort were presented at initial treatment, posttreatment 1, 3, 6, 9, and 12 months and yearly thereafter for 10 years.

Results

The characteristics and matching factors were well-balanced between the matched cohorts. Overall, surgery cohort spent $50.84/patient/month, while the nonsurgical cohort spent $29.34/patient/month (p<0.01). Initially, surgery treatment led to more charge to NHIS ($2,762) than nonsurgical treatment ($180.4) (p<0.01). Compared with the non-surgical cohort, the surgery cohort charged $33/month more for the first 3 months, charged less at 12 months, and charged approximately the same over the course of 10 years.

Conclusion

Surgical treatment initially led to more government reimbursement than nonsurgical treatment, but the charges during follow-up period were not different. The results of the present study should be interpreted in light of the costs of medical services, indirect costs, societal cost, quality of life and societal willingness to pay in each country. The monetary figures are implied to be actual economic costs but those in the reimbursement system instead reflect reimbursement charges from the government.

Published: December 2021

Objective

The purpose of this study was to biomechanically compare the stability of first metatarsophalangeal (MTP1) joint arthrodesis with dorsally and medially positioned plates.

Methods

A physical model of the MTP1 joint consists of printed synthetic bones, a titanium locking plate and screws. In the experiments, samples with dorsally and medially positioned plates were subjected to loading of ground load character in a universal testing machine. Force-displacement relations and relative displacements of bones were recorded. The obtained results were used to validate the corresponding finite element models of the MTP1 joint. Nonlinear finite element simulations of the toe-off phase of gait were performed to determine the deformation and stress state in the MTP1 joint for two positions of the plate.

Results

In numerical simulations, the maximum displacement in the dorsal direction was noticed at the tip of the distal phalanx and was equal to 19.6 mm for the dorsal plate and 9.63 mm for the medial plate for a resultant force of 150 N. Lower relative bone displacements and smaller plastic deformation in the plate were observed in the model with the medial plate. Stress values were also smaller in the medially positioned plate and locking screws compared to fixation with the dorsal plate.

Conclusions

A medially positioned locking plate provides better stability of the MTP1 joint than a dorsally positioned plate due to greater vertical bending stiffness of the medial plate. Smaller relative bone displacements observed in fixation with the medial plate may be beneficial for the bone healing process. Moreover, lower stress values may decrease the risk of complications associated with hardware failure.
