Προβληματική & εφαρμογές της επιστημονικά τεκμηριωμένης αποτελεσματικότητας της ψυχοθεραπείας
Authors: Κουστένη Ιωάννα
Published: August 2021

Τις δύο τελευταίες δεκαετίες λίγα ζητήματα έχουν απασχολήσει τόσο έντονα την επιστημονική κοινότητα, όσο η αντιπαράθεση σχετικά με τα πλεονεκτήματα και τα μειονεκτήματα ή τη δυνατότητα παροχής των επιστημονικά τεκμηριωμένων ψυχολογικών παρεμβάσεων. Αυτή η συνεχιζόμενη διαμάχη είναι το καθοριστικό στοιχείο ενδιαφέροντος της παρούσας διατριβής. Η διερεύνηση του πεδίου μελέτης βασίζεται σε πέντε βασικά ερωτήματα γύρω από το φαινόμενο της επιστημονικά τεκμηριωμένης ψυχοθεραπείας: 1) Πρώτον, τα δεδομένα είναι δυνατόν να συμπεριλάβει ένας λειτουργικός ορισμός της ψυχοθεραπείας εξετάζοντας τις συνθήκες και τα στοιχεία που εμπλέκονται στη διαχρονική της εξέλιξη έως τη σύγχρονη εποχή. 2) Δεύτερον, με ποια επιχειρήματα υποστηρίζουν οι επιστήμονες την αποτελεσματικότητα της ψυχοθεραπείας ως παρέμβαση για τις ψυχολογικές διαταραχές. 3) Τρίτον, τι συμπεριλαμβάνουν η έννοια και οι επιταγές του κινήματος της επιστημονικά τεκμηριωμένης ψυχοθεραπείας. 4) Τέταρτον, ποια είναι η κριτική που δέχεται το προαναφερόμενο κίνημα στο διεθνές βιβλιογραφικό στερέωμα. 5) Πέμπτον, με ποιο τρόπο η πολιτική και οικονομική πραγματικότητα των δυτικών κοινωνιών συνδέεται με και επηρεάζει την εξέλιξη του επιστημονικού πεδίου της ψυχοθεραπείας και συγκεκριμένα την ανάδυση και ισχυροποίηση του κινήματος της επιστημονικά τεκμηριωμένης ψυχοθεραπείας. Η μέθοδος που ακολουθήθηκε προς απάντηση στα προαναφερόμενα ερωτήματα είναι, καταρχήν, η συνολική εποπτεία, μελέτη και ανασκόπηση της διεθνούς βιβλιογραφίας (κυρίως του αγγλοσαξονικού χώρου, αλλά όχι μόνο) πάνω στον ζήτημα της τεκμηριωμένης ψυχοθεραπείας. Η παρούσα μελέτη επιχειρεί όχι μόνο την παράθεση αλλά και τη σύνθεση δεδομένων του ιστορικού, ερευνητικού και κοινωνικοπολιτικού πεδίου, εφόσον αποτελεί μια προσπάθεια να μελετηθεί το ευρύ θέμα της τεκμηριωμένης ψυχοθεραπείας, τόσο από επιστημονική-μεθοδολογική, όσο και από ιστορική, κοινωνική, ηθική και οικονομικο-πολιτική προοπτική. Τελικός στόχος είναι η κριτική αποτίμηση του φαινομένου της τεκμηριωμένης ψυχοθεραπείας, η θεώρηση των θετικών και αδύναμων σημείων του, εξελίσσοντας όμως την αξιολόγησή του σε ένα ακόμη πεδίο, και συγκεκριμένα, στο κοινωνικοπολιτικό πλαίσιο αναφοράς του. Εν τέλει, η μελέτη του φαινομένου της τεκμηριωμένης ψυχοθεραπείας δεν μπορεί να αποκοπεί, αλλά συνδέεται άρρηκτα με τις οικονομικές και πολιτικές επιταγές της παρούσης ιστορικής στιγμής.

Η διδακτορική διατριβή ερευνά την περιοχή της αιτιότητας ιδωμένης στο πλαίσιο της θεωρίας της Συνάφειας (Relevance) και άλλων γνωστών θεωριών με πραγματολογική και σημασιολογική προσέγγιση. Πέρα από την πληρέστερη κατανόηση του φαινόμενου της αιτιότητας, έχει απώτερο διδακτικό σκοπό την εμπεριστατωμένη επιστημονική ενημέρωση των σύγχρονων διδακτικών συγγραμμάτων γραμματικής και συντακτικού. Πιο συγκεκριμένα, η διατριβή εξετάζει το σύνολο των εννοιολογικών διαφορών ανάμεσα στους δύο πρωτοτυπικούς αιτιολογικούς συνδέσμους της υπόταξης στη Νέα Ελληνική παρατηρώντας τη συμπεριφορά τους στα πλαίσια των χρήσεών τους (context). Με δεδομένο ότι η γλώσσα αποτελεί το κατεξοχήν εργαλείο επικοινωνίας, εξετάζεται η δυνατότητα θεραπείας του παραπάνω ζητήματος στη βάση γνωστικής-πραγματολογικής προσέγγισης. Μέσα από μια σειρά θεωριών υπονοήματος καταδεικνύεται η διαφοροποιημένη χρήση και συμπεριφορά των συνδέσμων ως δεσμευτικών γλωσσικών στοιχείων σήμανσης της αιτιότητας ως προς τη συμβολή τους στην επίτευξη συντονισμού επικοινωνίας με μέσο στην έκφραση αιτιολογικών προτάσεων. Παράλληλα, αυτή η παρατήρηση εμφανίζει τα σημεία υπεροχής ή υστέρησης τόσο των μεθόδων εννοιολογικών αναλύσεων που υιοθετούνται όσο και των διαφόρων περιγραφών αιτιολογικών εννοιών που έχουν προσφέρει έως τώρα αποτελέσματα. Η προτεινόμενη μέθοδος εννοιολογικών αναλύσεων καταλήγει να είναι αυτή της συνάφειας, ως μέθοδος που παρουσιάζει μεγαλύτερη ευαισθησία σε επικοινωνιακές παραμέτρους, π.χ. τύποι υπονοήματος, εγκυκλοπαιδική γνώση, πλαίσια επικοινωνιακής κατάστασης, παράγοντες σύνθεσης του συνεχούς λόγου. Η συγκεκριμένη ερευνητική πρόταση απορρέει, κατά βάση, ως αντίδραση στα προβλήματα που ταλανίζουν την παράδοση της πραγματολογικής ανάλυσης, έτσι όπως αυτή διαμορφώθηκε στο πέρασμα των τελευταίων δεκαετιών από τις κατευθύνσεις του Grice.

Κατά την εκπόνησης της διδακτορικής διατριβής έγινε βιβλιογραφική ανασκόπηση με σκοπό την ανεύρεση μεθόδων μη καταστροφικού ελέγχου, οι οποίες συνδυάζονται με υπολογιστικές μεθόδους. Χρησιμοποιήθηκαν υπάρχοντες και νέοι συνδυασμοί και παρουσιάζονται τα αποτελέσματα τους. Η διατριβή χωρίζεται σε τέσσερα μέρη: Το πρώτο αφορά στην παραμετρική ανάλυση και σύγκριση αλγορίθμων επίλυσης αντίστροφων προβλημάτων για την εκτίμηση μηχανικών αλλοιώσεων. Η σύγκριση αφορά στις μεθόδους βελτιστοποίησης ή τεχνητών νευρωνικών δικτύων, στις μεθόδους επίλυσης του ευθέως προβλήματος και στην επίδραση της τοπολογίας, του μεγέθους της μορφής και του πλήθους των αλλοιώσεων. Τα είδη των ατελειών είναι κυκλική ή έλλειψη, με συγκεκριμένο ή προς ανεύρεση προσανατολισμό. Τα στοιχεία εισόδου αποτελούνται από πλήθος μετατοπίσεων του συνόρου. Το δεύτερο αφορά στην διερεύνηση και αξιολόγηση της επίδρασης της τοπολογίας και της διάστασης αποκολλήσεων πολυστρωματικών δομών, όπως έργα τέχνης και σύνθετα υλικά. Κατασκευάστηκαν υπολογιστικά μοντέλα και τα αποτελέσματά τους οδήγησαν στην παραγωγή εικόνων ολογραφικής συμβολομετρίας διπλής έκθεσης, όπως συμβαίνει στις πειραματικές μετρήσεις. Εφαρμόστηκαν δύο τύποι φόρτισης, η επιβολή θερμοκρασιακής διαφοράς και πίεσης κενού. Προσδιορίστηκαν τα όρια και η εξεύρεση τρόπων διεύρυνσης της μεθόδου. Το τρίτο μέρος αφορά σε υπολογιστικά μοντέλα ρωγμών και σε διαγνωστικές μεθόδους. Εκτιμήθηκε η ορθότερη μοντελοποίηση επίπεδης κατάστασης (εντατικής ή παραμορφωσιακής) δοκού με επιφανειακή ρωγμή σε σχέση με την πλήρη τριδιάστατη που ενσωματώνει θεωρία επαφής στα χείλη της ρωγμής. Επιπλέον, αναλύθηκε επίπεδη πλάκα με επιφανειακή ρωγμή υπό καμπτική φόρτιση. Με επεξεργασία των χωροχρονικών αποτελεσμάτων προέκυψαν οι ορθοκανονικές μορφές, στις οποίες εφαρμόστηκε αλγόριθμος διάγνωσης βασισμένος σε καμπύλες spline, με καλά αποτελέσματα. Το τέταρτο μέρος άφορα στη μελέτη μηχανικής συμπεριφοράς πολυμερικών επιστρώσεων σε ανόργανο υπόστρωμα κατά την διαδικασία φωτοαποδόμησης. Κατασκευάστηκαν υπολογιστικά μοντέλα μέσω των οποίων εκτιμήθηκε η σπουδαιότητα δράσεων της φωτοαποδόμησης στη δημιουργία ή επέκταση μηχανικών αλλοιώσεων σε περιοχές μακρύτερα από την περιοχή προσβολής. Τέλος, πραγματοποιήθηκε μικρής έκτασης παραμετρική ανάλυση που αφορούσε στα πάχη των στρωμάτων των δύο υλικών και στον χρόνο διάρκειας της φόρτισης. Η μελέτη ολοκληρώθηκε με τη διερεύνηση της επίδρασης ύπαρξης μικρής ατέλειας, σε περιοχή μακράν της προσβολής, στην ανάπτυξη τάσεων.
Διερεύνηση της συμπεριφοράς οδήγησης ηλικιωμένων οδηγών στον αυτοκινητόδρομο και των αντιλήψεών τους για θέματα οδικής ασφάλειας
Authors: Βαρδάκη Σοφία
Published: August 2021

Οι στόχοι της παρούσας έρευνας ήταν η διερεύνηση της επίδοσης των ηλικιωμένων οδηγών σε πραγματικές συνθήκες οδήγησης στον αυτοκινητόδρομο, οι συσχετίσεις μεταξύ της αντισταθμιστικής συμπεριφοράς και της ασφαλούς οδήγησης, καθώς και οι συσχετίσεις μεταξύ της αξιολόγησης της επίδοσης, της αυτοαξιολόγησης της επίδοσής τους στον αυτοκινητόδρομο και των αντιλήψεών τους για θέματα οδικής ασφάλειας. Για την επίτευξη αυτών των στόχων 40 άνδρες οδηγοί με άδεια και με δραστηριότητα οδήγησης ηλικίας από 65-74 ετών συμπλήρωσαν ένα ερωτηματολόγιο αντιλήψεων για θέματα οδικής ασφάλειας και σε επόμενο στάδιο αξιολογήθηκε η επίδοσή τους στην ασφαλή οδήγηση σε ένα πείραμα πεδίου σε αστικό αυτοκινητόδρομο. Οι οδηγοί μετά το πείραμα συμπλήρωσαν ένα ερωτηματολόγιο αυτοαξιολόγησης της επίδοσής τους στη συγκεκριμένη διαδρομή. Σύμφωνα με τα αποτελέσματα της έρευνας η αντισταθμιστική συμπεριφορά που εκδηλώθηκε από τους οδηγούς στη διάρκεια της οδήγησης συσχετίζεται με μειωμένη επίδοση σε διάφορες μεταβλητές οδήγησης στον αυτοκινητόδρομο. Προβλήματα επίδοσης που αναδείχθηκαν μπορεί να βελτιωθούν με κατάλληλους τρόπους προσαρμογής και ασφαλείς πρακτικές. Τα αποτελέσματα των συσχετίσεων της επίδοσης στον αυτοκινητόδρομο, της αυτοαξιολόγησης της επίδοσης τους και των αντιλήψεων σε θέματα οδικής ασφάλειας υποδεικνύουν ότι οι ηλικιωμένοι οδηγοί αναγνωρίζουν τυχόν μειωμένη επίδοσή τους στον αυτοκινητόδρομο. Επίσης αναδεικνύεται η αντίληψη ορισμένων οδηγών για ανάγκη βελτίωσης της σήμανσης των εξόδων. Είναι ενδιαφέρον ότι οι οδηγοί αναγνωρίζουν την ανάγκη να βελτιωθούν οι επιδόσεις τους. Τα αποτελέσματα αυτά είναι σημαντικά για τον σχεδιασμό των αυτοκινητοδρόμων, την εκπαίδευση των ηλικιωμένων οδηγών, την αξιολόγηση και την αυτοαξιολόγησή τους.

Published: August 2021

Η διατριβή πραγματεύεται το θέμα της πρόσληψης και της μεταχείρισης των βυζαντινών μνημείων στην πρώτη εκατονταετηρίδα από την ίδρυση του ελληνικού κράτους (1833-1939). Σκοπός της διατριβής είναι, η εξιστόρηση των προσπαθειών που κατέβαλαν το νεοελληνικό κράτος και άλλοι μη κρατικοί θεσμοί για τη διάσωση της βυζαντινής κληρονομιάς, η εξέταση των αντιπροσωπευτικών επεμβάσεων αποκατάστασης σε βυζαντινά μνημεία στην Ελλάδα την περίοδο αυτή και τέλος, η διερεύνηση του ιδεολογικού και πολιτισμικού πλαισίου εντός του οποίου αναπτύχθηκαν οι προσπάθειες αυτές. Η διατριβή υποστηρίζει και τεκμηριώνει ότι η αντιμετώπιση των εκκλησιαστικών κτισμάτων από το νεοελληνικό κράτος εκφράζει την ιδεολογία του νέου κράτους και αντανακλά την ιστορική εξέλιξη της πρόσληψης του Βυζάντιου στην Ελλάδα σε όλη την υπό εξέταση περίοδο. Παράλληλα, επιβεβαιώνεται η ερευνητική υπόθεση της διατριβής για το ρόλο των ευρωπαϊκών επιρροών κι, μεταφορών στον τρόπο αντιμετώπισης της προστασίας και των επεμβάσεων αποκατάστασης των μνημείων. Οι ευρωπαϊκές αυτές επιρροές κατά την μεταφορά τους πλαισιώνονται με τις εσωτερικές ιδεολογικές και πολιτικές αντιπαραθέσεις και αποτελούν ένα ακόμα πεδίο συγκρούσεων με αναφορές, στην εθνική ταυτότητα, στην ιδεολογική λειτουργία των μνημείων και εν τέλει, στις σχέσεις κράτους και εκκλησίας.
The Effect of HRM Practices on Environmental Competence of Employees
Authors: Arzamasova G.
Published: August 2021

In a green business the environmental competence of employees becomes a key factor in the successful implementation of environmental strategies and performance. However, there is no approach to the understanding and development of environmental competence in the context of the organization and its effect on employee’s behavior to achieve the company's environmental goals. Based on a survey of employees of an industrial enterprise and structural equations modeling (SEM) the article empirically proved that environmental competence, as a combination of knowledge, skills and value characteristics of an employee is formed as a result of a set of environmental oriented HRM practices. Also, the results of the study showed that environmental competence has a direct positive impact on the behavior of employees in solving environmental problems in the workplace and contributes to increased participation in additional environmental activities, initiative and commitment to improving environmental performance. The results of the study contribute to the development of green HRM methodology by expanding the empirical base of research on the mechanisms for the development of environmental competence of employees.
Combined Custom Hedging: Optimal Design, Noninsurable Exposure, and Operational Risk Management
Authors: Guiotto Paolo , Roncoroni Andrea
Published: August 2021

Optimal Design of Combined Contingent Claims: Theory and Applications.

In “Combined Custom Hedging: Optimal Design, Noninsurable Exposure, and Operational Risk Management”, Paolo Guiotto and Andrea Roncoroni develop a normative framework for the optimal design, value assessment, and operations management integration of financial derivatives. Most business and operating revenues entail a mix of financially insurable and noninsurable risk. A risk-averse firm may face them by positioning in a pair of financial derivatives with optimal bespoke payoff functions; one claim is written on the insurable term, and the other claim is written on any observable index exhibiting correlation to the noninsurable term. On a theoretical ground, the authors 1) state the problem in a general setup and prove existence and uniqueness of the optimal pair of combined claims, 2) show that the optimal payoff functions satisfy a Fredholm integral equation, and 3) assess the incremental benefit the firm obtains by switching from the optimal single-claim custom hedge to the optimal combined custom hedge they propose. On an experimental ground, they show that 1) the optimal combined custom hedge would be empirically relevant for a highly risk-averse firm facing a market shock shown during the first period of the COVID-19 pandemic in 2020, 2) integration with the optimal procurement in a generalized newsvendor model leads to a significant improvement in both risk and return, and: 3) this gain can be traded off for a substantial enhancement in operational flexibility.

Abstract. Puspasari LT, Buchori D, Ubaidillah R, Triwidodo H, Hidayat P. 2021. Diversity of insect galls associated with Eucalyptus alba & E. urophylla in altitudinal zones in Timor Island, Indonesia. Biodiversitas 22: 2667-2679. We investigated the galling insects associated with two species of Eucalyptus, namely E. alba Reinw. and E. urophylla S.T. Blake in different altitudinal zones in Timor Island, Indonesia. This is the first report for Indonesia of the diversity patterns and community structures of galling insects in these two species of eucalyptus and the type of galls they produce. Surveys and data collection were carried out between October 2017 and June 2018 at different altitudes of secondary forest in Timor Tengah Selatan district, Timor. We visited five altitudinal zones (± 829 m asl., ± 942 m asl. ± 1,621 m asl., ± 1992 m asl., and ± 2457 m asl.) and selected 25 eucalyptus plants of 3 to 5 m in height in each altitudinal zone from which to collect insect galls. The galls were observed on leaves, upper leaves (shoots), outer leaves, symptomatic twigs and stems. The galls were taken to the laboratory for rearing of the insects they contained. A total number of 12 gall types were found in E. alba and 15 in E. urophylla from which 28 insect morphospecies were identified belonging to 16 families and five orders. The order Hymenoptera was represented by ten families: Bethylidae, Torymidae, Eulophidae, Eupelmidae Eurytomidae, Pteromalidae, Encyrtidae, Mymaridae, Braconidae and Scelinonidae while the order Diptera was represented by three families: Fergusoninidae, Cecidomyiidae and Chaoboridae. Galling species diversity ranged from 1.71 to 2.38 on the Shannon-Wiener index and 0.75 to 0.87 on the Simpson index and showed that the galling-insect communities were species-rich and composed of galling formers and very few inquilines. In the study, communities are categorized and structured according to different types of galling insects, including those that induce galling, those that are parasitoid, and those that are inquiline. Within the category of gall-forming insects in the two species of eucalyptus, Eulophidae is found to be the dominant family. Our field data makes an important contribution to basic knowledge of insect galling patterns in eucalyptus forests and constitutes baseline data for the implementation of pest control.

Abstract. Mulya MB, Jhon AH, Harahap ZA. 2021. Population dynamics of anchovy pekto (Stolephorus waitei) in the waters of Malacca Strait, North Sumatra, Indonesia. Biodiversitas 22: 2693-2698. Anchovy pekto or Stolephorus waitei (Engraluidae: Clupeiformes) is one of the fish in the eastern coastal part of North Sumatra, occupying the waters of Malacca Strait. This research presents the population dynamics of S. waitei following its age, growth, mortality, and recruitment pattern based on the length-frequency data. Fork length (FL) and total weight (TW) data of S. waitei were collected at three sites from April to September 2018. A total of 1994 specimens with FL from 4.0 to 6.7 cm and TW from 0.2 to 2.3 g with the length-weight relationship of TW = 0.073FL3.0046 (R2=0.765) indicated a near isometric and positive allometric growth in the water region. The relative condition factor (Kn) ranged from 1.01 to 1.02, indicating an estimate of good condition of the fishes. The growth parameters based on von Bertalanffy was 6.56 cm (L?) with the growth coefficient (K) of 0.34 yr-1 and t0 (anchovy age at zero length ) of 0.6506. The total mortality (Z), natural mortality (F), and catch mortality (M) of S. waitei were 0.64, 1.39, and 0.75 yr-1 respectively, which suggest that the fishing activities of S. waitei are still in normal intensity. The recruitment pattern of S. waitei was stable between April and August with its peak in June by 14.21%. The fishing activities may then be limited during the spawning months (May to June) of S. waitei to maintain their population in the Strait of Malacca.

Biodiversitas 22: 2699-2710. The release of Bali Mynah (Leucopsar rothschildi Stresemann, 1912) is an attempt to return the bird population to its natural habitat to increase the number of Bali Mynah populations in nature. Bali Mynah population release results that can grow, but slow rate, so that indicates to review technical and management evaluation of Bali Mynah release. The study aims to evaluate the development of the population, the factors that affect population numbers and habitat for the results of releasing Bali Mynah, as well as the security factor. The research was conducted and focused on the Breeding Centre of Bali Mynah (BCBM) in Tegal Bunder, Teluk Brumbun, Teluk Kotal, Tanjung Gelap, and Pos Lampu Merah of Bali Barat National Park (BBNP), Indonesia from May to June 2015. The method of data collection is direct observation, measurement (population with concentration method), interview in relation to management of the bird, and literature. Data analysis was done by calculating the score of the assessment and the animal welfare. The result shows that the Bali Mynah population in Breeding Centre of Bali Mynah in Tegal Bunder has been categorized as good (analyzed from the animal welfare and assessment of the Bali Mynah with a score of 76.53 and 4.32 respectively). Bali Mynah population in the release area is well developed. The BM population has shown survival supported by an abundance of food and water availability, but the movement is still limited (500 m-1000 m) from the release areas.

Abstract. Krupnova TG, Naumova NL, Rakova OV, Burmistrova OM, Burmistrov EA. 2021. Apple trees as a possible monitor and phytoremediator of urban and industrial areas in Chelyabinsk, Russian Federation. Biodiversitas 22: 2824-2828. Apple trees are cultivated worldwide and are the most widely grown fruit crops in the South Ural region. This study examines the suitability of apple trees for biomonitoring and phytoremediation. We collected the leaves and fruits of the apple (Malus domestica Borkh.) trees and the surrounding soil from three areas in Chelyabinsk, a typical Russian industrial city. The leaves, fruits and soils were analyzed for metal(loid) content (As, B, Cd, Co, Cr, Cu, Fe, Ga, In, Hg, Mn, Ni, Pb, Se, Sn, Sr, and Zn). The results were obtained using mass spectrometry with inductively coupled plasma (ICP-MS). We found a response in the apple tree defense system to the action of heavy metals in the synthesis of biologically active substances. The data gave information about the environmental state of soils collected in the zones of influence of metallurgical industrial enterprises. However, the trees did not assimilate or tolerate high concentrations of metal(loid)s in the leaves and they cannot be recommended for phytoremediation.

Abstract. Bahry MS, Radjasa OK, Trianto A. 2021. Potential of marine sponge-derived fungi in the aquaculture system. Biodiversitas 22: 2883-2892. Organic waste from aquaculture is one of the triggers of disease outbreaks and a decrease in water quality that urgently needs to be resolved. Indonesia has a high diversity of sponges including their associated microorganisms that potential in the field of biotechnology. This study aimed to determine the enzymatic and anti-vibrio activity of fungi associated with marine sponges and identify potential fungi. The specimen of sponges was collected from Samalona Island, South Sulawesi, Indonesia. The enzymatic and anti-vibrio assay was conducted by using the plug method and the activity was determined by a clear zone around the fungal isolates. Fungal identification was carried out molecularly using universal primers ITS1 and ITS4 and phylogenetic tree analysis. The fungal isolates were screened for the extracellular enzyme activity (amylase, cellulase, protease) and anti-vibrio activity against Vibrio parahaemolyticus, V. harveyi, and V. vulnificus). A total of three fungal isolates have been isolated from the sponge Monanchora sp. Isolate SL 3 SP 3.3 had potential enzymatic activities with Enzymatic Indeks (EI) 3.95±0.17 on amylase, 3.75±0.36 on cellulase, 5.38±0.30 on protease. The highest anti-vibrio activity was obtained against V. harveyi with an inhibition zone diameter of 4.82 ±0.37 mm. The results of fungal identification showed that isolate SL3SP3.3 had a sequence length of 638 bp and was closely related to Trichoderma reesei a.k.a Hypocrea jecorina with a similarity value of 99.69%.

Abstract. Jana CL, Jusoh I. 2021. Structure and Tree Species Composition of Forest Fringe of A Forest Fragment in an Oil Palm Plantation at Suai, Sarawak, Malaysian Borne. Biodiversitas 22: 3013-3019. Forest fragments in oil palm plantations are remnants of the original forest tract with various sizes and shapes after clearing forested lands for crops and roads. Fragmented forests usually created forest fringe or edge habitats that differ in light intensity, temperature, humidity, heavy rainfall, and strong winds from its core. The study was aimed to determine the structure and tree species composition of the forest fringe of a fragmented forest in an oil palm plantation Suai, Sarawak. This study established a total of 24 sampling plots within the forest fringe. Tree enumeration and species identification were conducted in all sampling plots to all trees with a diameter at breast height 5 cm and higher.  A total of 59 families comprised of 274 species and 948 trees individuals were recorded. The aboveground biomass stand at 260 Mg ha?¹. Species Elateriospermum tapos was predominant, and family Dipterocarpaceace dominated the forest fringe.   Based on the calculated indices, species diversity and richness were considered high, while the dispersion of individual trees was random but unevenly distributed. Natural regeneration in the forest fringe is sustainable. The forest structure and species composition are intact, and without significant disturbance, the whole forest fragment is self-sustain.

Abstract. Ayodya FP, Wijayanti DP, Sabdono A. 2021. Lunar cycle and reproductive activity of Redbelly yellowtail fusilier, Caesio cuning in Karimunjawa National Park, Indonesia. Biodiversitas 22: 3075-3082. Redbelly yellowtail fusilier (Caesio cuning) is known as fish that has been widely distributed among Southeast Asian countries. Fishers in Indonesia especially target the species, causing the scarcity and depletion of the catch in many fisheries areas each year. One of the priority aspects in improving fisheries management in conservation areas is information regarding reproductive activities. Many reports suggested that the lunar cycle affects the reproductive activity of fishes. However, none of the studies reported on the effect of lunar cycle on the reproductive activity of C. cuning. This study aimed to explain the lunar cycle effect on the reproductive activity of C. cuning through gonadosomatic index (GSI), viscerosomatix index (VSI), and the observation of oocyte conditions. There were 374 individual fishes collected from Nyamuk Island, Karimunjawa from September to November 2020. Samples were taken in each phase and between major phase of the moon (new, first quarter, full, last quarter) during two lunar cycles. The results point out mature gonad (stage IV and V) was present around the new moon. The peak of female GSI occurred around the last quarter moon with figures 6.12 and 5.51% respectively. The condition of the mature oocyte and ovulation were present around the last quarter and the new moon. The condition indicates imminent spawning.

Biodiversitas 22: 3113-3118. Dragon fruit (Hylocereus spp.), belonging to Cactaceae family, is one of the horticultural commodities being developed in Indonesia for export. Phytosanitary regulations require that fruits for export must be free from diseases and pests, including mealybugs (Hemiptera: Pseudococcidae). Mealybug species commonly found on dragon fruits in Indonesia are Ferrisia virgata (Cockerell), Phenacoccus solenopsis Tinsley, Planococcus minor (Maskell) and Pseudococcus jackbeardsleyi Gimpel & Miller. Species-level identification of these insects in the nymphal phase is difficult due to the limited number of identification keys available, so it has been necessary to create an identification key to nymphs of mealybug species found on dragon fruit. A dichotomous identification key was constructed based on microscopic morphological characteristics of the cuticle. Thus, the four species can be differentiated based on general and unique characteristics of each species in the nymphal and adult stages. The diagnostic features that can be used to separate the four species in the nymphal phase are the presence or absence of: discoidal pores around the eyes; anal lobe bars; tubular ducts on the dorsum; and a denticle on each tarsal claw.

Abstract. Putra ETS, Purwanto BH, Wulandari C, Alam T. 2021. Metabolic activities of eight oil palm progenies grown under aluminum toxicity. Biodiversitas 22: 3146-3155. In Indonesia, oil palm is mostly cultivated on red-yellow podzolic soils, which mainly contain the high availability of aluminum (Al). This condition might affect oil palm growth i.e stunted growth and root damage. Therefore, this study was aimed to characterize metabolic activities and growth of eight oil palm progenies under Al toxicity. The study was conducted from January to December 2018 in Bendosari Hamlet, Madurejo Village, Prambanan Sub-District, Sleman District, Province of Yogyakarta, Indonesia. The trial was laid out in a randomized complete block design (RCBD) factorial with three blocks as replications, with experimental factors including oil palm progenies and Al concentration. The observation was conducted on Al concentration in the planting medium, metabolic activities, and oil palm growth. The data were analyzed using ANOVA, PLS-SEM, stepwise regression, hierarchical clustering heatmap, and GGE-Biplot. The results showed that Simalungun, Dumpy, and Yangambi progeny could grow and adapt better than other progenies in Al toxicity conditions. The resistance to Al poisoning mechanism was shown by a relatively low activity of O2-, H2O2, MDA, and REL, whereas SOD, POD, GB, AARed, ?-Toch, TPC RDW and, SDW showed higher relatively.

Abstract. Sulaeman TN, Hamidy A, Farajallah A, Fouquet A, Riyanto A, Arida E, Mulyadi, Trilaksono W, Munir M. 2021. Mitochondrial DNA suggests the existence of two distinct species in Moluccas and New Guinea within Nyctimystes infrafrenatus (Günther, 1867). Biodiversitas 22: 3287-3297. Nyctimystes infrafrenatus is a widespread frog species distributed across northern Australia, New Guinea, Bismarck archipelago and in the eastern part of Indonesian archipelago. The species thus encompasses two biogeographic regions, Papua and Wallacea. We evaluated the phylogenetic relationships among the populations from Papua and Moluccas based on two mitochondrial loci (16S rRNA and Cytochrome Oxidase Subunit I). Two major subclades are recovered within Nyctimystes infrafrenatus with subclade A being represented by populations from New Guinea and northern Australia and subclade B by Moluccan populations (Halmahera and Tidore). Genetic distances (2.3-4.2% in 16S rRNA) between these subclades suggest they could belong to distinct species. Since New Guinea populations correspond to the nominal species and that Nyctimystes tennuigranulatus (Boettger 1895), currently considered as a junior synonym of Nyctimystes infrafrenatus, is available for the northern Moluccan populations, we proposed to remove this taxon from synonymy. However, samples used in this study come from northern Moluccas, further studies including samples from Ambon (where another synonym was described i.e. Calamita dolichopsis) is needed to determine the taxonomic status of the southern Moluccan population whether they are conspecific with northern Moluccan population or not.

Bird diversity and ethno-ornithological knowledge of local people in Ciletuh-Palabuhanratu Geopark, Sukabumi, West Java, Indonesia. Biodiversitas 22: 3409-3422. Birds have ecological and social functions, and are common to be used as bioindicators of environmental changes. Birds are very important consideration when establishing conservation areas, including geopark which has uniqueness in terms of geological, biological and cultural diversities. This study aimed to investigate the bird diversity in Ciletuh-Palabuhanratu Geopark, West Java, Indonesia and as well as to reveal the local knowledge on bird species and folk classification, functions and utilization of birds among the village people. Mixed methods of quantitative and qualitative approaches were applied in this study, while some techniques, including semi-structured interviews, structured interviews, and bird observation on transect and spotlighting were employed to collect the primary data. In total, there were 121 bird species of 47 families of which 88 species were recorded during the field observation and 79 species were documented through the interviews with respondents. Among them, 12 species are listed as having high conservation status under IUCN, 17 species are listed as Appendix II (CITES), and 21 species are listed by Regulation of the Minister of Environment and Forestry of the Republic Indonesia No. P 106/2018 on Protected Plant and Animal Species. The local community has profound knowledge of birds species, folk classification, ecological, socio-cultural, and socio-economic functions. In the past, the village people had traditional beliefs and myths on birds, resulting in some sacred birds had been traditionally conserved. Nowadays, these are no longer strongly existed, and consequently, many birds have been hunted by using different methods of hunting birds, both traditional and modern for various purposes, including for consumption, bird keeping, and trading to obtain cash. Therefore, bird conservation efforts that involve the community are really needed in this area as the strategy of sustainable management of Ciletuh-Palabuhanratu Geopark.

Abstract. Limbongan YL, Driyunitha, Sjahril R, Riadi M, Jamaluddin I, Okasa AM, Panga NJ. 2021. Heritability and genetic advancement on agronomic characters of Toraja red rice x Inpari-4 white rice genotypes. Biodiversitas 22: 3446-3451. Determination of genetic diversity, heritability, and genetic advance on specific agronomic characters of cross-breed red rice genotypes (Toraja red rice Pare Lea’ x Inpari-4) was done in Tallunglipu, North Toraja, South Sulawesi, Indonesia. The experiment was designed using a randomized complete block design. Twenty-one days old seedlings were transplanted following the system of rice intensification practices. Selection was conducted at F2 as a novel method to speed up genetic advancement and ensure progeny production with desired agronomic traits. Results indicated existence of a considerably high level of diversity among genotypes tested, where the highest value for genetic advance was observed in filled-grain weight per hill of F2 plants (983.890), followed by plant height (335.124), and filled-grain weight per hill of F1 (306.645). The highest estimate of broad-sense heritability was recorded in 1000-grain weight (0.915), number of productive tillers (0.788), plant height (0.765), flag leaf length (0.705), filled-grain weight per hill (0.688), and harvest age (0.594). Genetic advance of agronomic characters between genotypes varied from 1.631-38%, where the highest estimate was recorded in filled-grain weight per hill (38%) and plant height (24.648%). The above-mentioned characters could be used for selection in further rice breeding programs to obtain plants with superior genotypes.

Authors: Petronis Sandris , Jakusonoka Ruta , Linovs Viktors , Jumtins Andris
Published: August 2021

Introduction: The increasing number of primary total hip replacements means that there is an increased need for hip arthroplasty revisions. The periprosthetic fractures which cause bone defects can occur during removal of the femoral component and healing of these fractures can be delayed. In femoral bone defects during revisions, there are no metal augments for filling these defects.
Case Report: Fifty-nine-year-old female presented with infected loosening of the left hip non-cemented endoprosthesis 5 years after surgery. The patient underwent removal of endoprosthesis. In 2 months, re-implantation of non-cemented endoprosthesis was performed and biphasic calcium phosphate (BCP) ceramic granules with hydroxyapatite/?-tricalcium phosphate (HAp/?-TCP) were implanted in the femoral bone defects. Eleven months following the arthroplasty patient had periprosthetic fracture of the distal third of the left femur. The osteosynthesis was performed and BCP ceramic granules with HAp/?-TCP were used to fill the bone defect. Long-term follow-up showed very good functional outcome and bone defect healing.
Conclusion: The BCP ceramic granules with HAp/?-TCP material adjusted to the bone defect anatomy, showed effective femoral bone defect and periprosthetic fracture healing in a patient with hip arthroplasty revision and periprosthetic fracture.
Keywords: Bone defect, femoral, revision.

Published: August 2021

Introduction: In this modern era, limb reconstructive surgeries have become a standardized procedure for malignant tumor of lower limbs. We performed limb salvage surgeries for tumor around the knee with en bloc resection and subsequent reconstruction with a megaprosthesis.
Methods: A total of six cases of malignant and locally aggressive tumor around the knee were operated on from 2017 to 2018, with resection and mega prosthetic reconstruction. Interpretation of functional outcome after surgery was performed with musculoskeletal tumor society (MSTS) score. Complications such as infection, local recurrence of tumor, implant failure, and distant metastases were evaluated during each follow-up.
Results: Postoperatively, one patient developed superficial infection; one local recurrence with metastasis and the rest cases were uneventful. Patients were regularly followed for atleast1 year, and none of them developed any sign of deep infection, implant failure,or loosening. At the beginning of treatment, the average MSTS score was 8.83, which showed a significant increment to 25.83 after 12 months of follow-up.
Conclusion: Albeit few cases were operated on, we draw this inference from our short-term experience that mega prosthesis acts as a boon to orthopedic surgeons in musculoskeletal tumor management, thereby uplifting the quality of life of patients even during terminal care.

A Rare Case of Pseudoaneurysm of the Brachial Artery in Supracondylar Humerus Fracture
Authors: Kulkarni Shrihari L , Daragad Manjunath S , Mannual Sunil , Krishna Yashwanth
Published: August 2021

Introduction: Supracondylar humerus fractures are very common fractures in children. About 10–14% are associated with vascular complications. We report a rare case of pseudoaneurysm of the brachial artery which was promptly detected in a well-perfused hand nearly 2 weeks after reduction and fixation.
Case Report: A 10-year-old girl with Type I open supracondylar fracture of the left humerus (Modified Gartland Type 2) presented 2 weeks post-fixation with pulsatile mass in the elbow. Imaging revealed a pseudoaneurysm of brachial artery which was managed by excision and reconstruction using great saphenous vein graft. The fracture united uneventfully and the child made a full return to pre-fracture level of activity.
Conclusion: The case highlights the occurrence of pseudoaneurysm of brachial artery, a rare complication seen few days or weeks after the injury, which coincides with the post-operative period in children managed by surgical fixation. This emphasizes the need for periodic monitoring of the neurovascular status of the children even after successful reduction and fixation.
Keywords: Supracondylar humerus fracture, vascular complication, pseudoaneurysm.
Orthorexia nervosa and disordered eating attitudes among Lebanese adults: Assessing psychometric proprieties of the ORTO-R in a population-based sample
Authors: Hallit Souheil , Brytek-Matera Anna , Obeid Sahar
Published: August 2021

Background

Previous research demonstrated a relationship between ON and disordered eating symptoms (eating concern, restraint, cognitive preoccupations about body shape and weight) and disordered eating attitudes (DEA). Since screening for orthorexia nervosa is now part of clinical practice, the measurement instruments to be used must be clinically significant, reliable, valid and sensitive to our target population. The main objective of the present study was to confirm the factor structure of the Arabic version of the ORTO-R using a first sample of Lebanese adults and confirm those results on another sample. The secondary objective was to assess sex differences in terms of ON and DEA, as well as to examine whether symptoms of ON were related to DEA in Lebanese adults.

Methods

A total of 783 Lebanese adults was selected to participate in this cross-sectional study (January-May 2018) using a proportionate random sample from all Lebanese governorates.

Results

The mean age of the total sample was 27.78 ± 11.60 years (Min. 18 –Max. 84) (33.5% females) and their mean BMI was 24.36 ± 5.31 kg/m2. All items of the ORTO-R were extracted during the factor analysis and yielded a two-factor solution with Eigenvalues > 1 (variance explained  =  50.07%; KMO = 0.570; Bartlett’s sphericity test p<0.001; αCronbach = 0.755). This factor structure was confirmed by a confirmatory factor analysis; the Maximum Likelihood Chi-Square  =  26.894 and Degrees of Freedom  =  8, which gave a χ2/df  =  3.36. The Tucker Lewis Index (TLI) value was 0.914, whereas the standardized root mean square residual (SRMR) value was 0.032. The root mean square error of approximation (RMSEA) value was 0.077 [95% CI 0.046–0.111] (pclose = 0.07) and comparative fit index (CFI) value was 0.967 respectively, indicating a good fit of the model. There was also no measurement invariance between genders. Female gender was significantly associated with lower ORTO-R scores (more orthorexia nervosa) compared to males (B = -0.65; p = 0.026, 95% CI -1.22- -0.08; ɳ2 = 0.006). However, no significant difference was found between genders in terms of EAT-26 scores (B = 0.23; p = 0.813, 95% CI -1.66–2.12; ɳ2 = 0.0001). Higher ORTO-R scores (lower/ less pathological ON tendencies and behaviors) were significantly related to higher EAT-26 total scores (higher levels of DEA) as well as higher dieting, bulimia and oral control scores in both females (from a weak to a moderate positive correlation) and males (a weak positive correlation).

Conclusion

This cross-sectional population-based study confirmed the factor structure of the Arabic version of the ORTO-R, demonstrated an association between ON and DEA and revealed more ON among females compared to males.

Background

Eswatini has the highest global prevalence of HIV despite decades of universal access to free antiretroviral therapy (ART). We conducted a mixed methods study to investigate barriers to ART adherence among women living with HIV (WLHIV) in rural communities of Eswatini. Qualitative findings were reported in our previous publication. This subsequent paper expands on our qualitative analysis to examine the magnitude to which identified barriers impacted ART adherence among WLHIV in the same communities.

Methods

We used an exploratory sequential design to collect data from WLHIV (n = 166) in rural Eswatini. Quantitative data were collected using interviewer-administered survey questionnaires between October and November 2017. ART adherence was measured using the CASE Adherence Index, with scores less than 10 indicating nonadherence. Log-binomial regression models were used to examine the extent to which critical barriers affected ART adherence among study participants.

Results

A majority of the women in our study (56%) were nonadherent to ART. Of the barriers identified in our prior qualitative analysis, only eight were found to be significantly associated with ART nonadherence in our quantitative analysis. These include, with adjusted risk ratios (ARR) and 95% confidence intervals (95% CI): household food insecurity (ARR: 3.16, 95% CI: 1.33–7.52), maltreatment by clinic staff (ARR: 2.67, 95% CI: 1.94–3.66), forgetfulness (ARR: 1.80, 95% CI: 1.41–2.31), stress (ARR: 1.47, 95% CI: 1.14–1.88), gossip (ARR: 1.57, 95% CI: 1.21–2.04), mode of transport (ARR: 0.59, 95% CI: 0.44–0.79), age (ARR: 0.98, 95% CI: 0.97–0.99), and lack of community support (ARR: 0.55, 95% CI: 0.35–0.85).

Conclusions

Among numerous barriers identified in our study, food insecurity was found to be a significant contributor toward ART nonadherence among women living with HIV in rural Eswatini. Future strategies aimed at improving ART adherence in Eswatini should include programs which provide food and nutrition support for people living with HIV, particularly rural women living in poverty.

Published: August 2021

Background Sepsis is life-threatening organ dysfunction caused by a regulated immune response to infection. Sepsis remains the most common cause of death in infants and children worldwide. The Pediatric Logistic Organ Dysfunction (PELOD-2) score, one of the most widely used scoring systems in pediatric sepsis patients, has been shown to be accurate in predicting mortality. The platelet-to-lymphocyte ratio (PLR) is a new clinical indicator of inflammation in a variety of diseases including sepsis.

Objective To investigate the relationship between PLR, PELOD-2 score, and clinical outcomes in pediatric patients with sepsis.

Methods This retrospective cohort study was conducted in the Pediatric Intensive Care Unit (PICU), Prof R.D. Kandou Hospital, Manado, North Sulawesi, from February to August 2020. Subjects’ PELOD-2 score and PLR were recorded once within the first 24 hours of PICU admission. We analyzed patients’ PELOD-2 score, PLR, and mortality rate, with 95% confidence interval (CI) for each value.

Results Of 96 children with sepsis admitted to the PICU during the study period, 87 patients (46 boys; 52.9%) met the inclusion criteria. In total, 50 (57.47%) patients were non-survivors. Mean PLR values among survivors [77.54 (SD 50.08)] was significantly lower compared to the values among non-survivors [157.13 (SD 67.38)]; as well as the PELOD-2 score in the survivors group [12 (SD 1.32)] was significantly lower than its value in the non-survivors [14.65 (SD 2.09)]. Spearman’s analysis showed a moderately positive correlation between PLR and PELOD-2 score (r=0.444; 95%CI 0.44 to 1; P<0.01). Biserial point correlation analysis revealed a significant association between PLR and mortality rate (rpb=0.566; P<0.0001),with elevated PLR related to an increased risk of mortality.

Conclusion There are positive correlations between PLR, PELOD-2 score, and mortality rate in pediatric patients with sepsis. Higher PLR and PELOD-2 score are associated with higher mortality.
