Authors: Zhang Junliang , Zheng Shuang , Hu Zhongzheng , Wang Jingming
Published: January 2024

Objective

A questionnaire was administered to 936 college students to investigate the mediating effect of psychological resilience in the association between mindfulness and college student depression, as well as the moderating role of gender.

Methods

For this study, data was collected between 20 April and 1 May 2023 at three universities in Jiangxi Province using a random sampling method. 963 Chinese university students were surveyed using the Adolescent Mindfulness Scale, the Psychological Resilience Scale, and the Depression Self-Rating Scale.SPSS24.0 software was used for correlation analysis and linear regression analysis, and PROCESS v3.4 model 7 was used to analyze this mediated model with moderating effects.

Results

In the mediated effects model, the direct effect of mindfulness on college depression levels was significant (95% CI -0.43, -0.31); the indirect effect of mindfulness on college depression through psychological resilience was also significant (95% CI -0.34, -0.23); the interaction effect of mindfulness and gender was also found to be significant (95% CI 0.03, 0.16) in the mediated model with moderation.

Conclusion

Mindfulness not only affect depression directly, but also indirectly through the mediating effect of psychological resilience. At the same time, the prediction of psychological resilience by mindfulness was also moderated by gender, with girls' psychological resilience being more affected by the level of mindfulness compared to boys.
The impact of the COVID-19 pandemic on mental health and quality of life in people living with and beyond breast, prostate and colorectal cancer – a qualitative study
Authors: Pini Simon , Buck Caroline , Lally Phillippa , Beeken Rebecca , Fisher Abigail
Published: January 2024

Background

Individuals living with and beyond cancer are at heightened risk of adverse psychological and social outcomes and experiences. In March 2020, the COVID-19 global pandemic presented a unique set of social circumstances with the potential to exacerbate the challenges faced by this population. The purpose of this study was to investigate the experiences of people living with and beyond cancer during the first year of the COVID-19 pandemic and assess the impact on psychological and social aspects of their lives.

Methods

From a pool of participants from a larger health behaviours study thirty participants were purposively sampled for characteristics including: diagnostic group (breast, prostate and colorectal cancers), gender, time since diagnosis and age. Semi-structured interviews were conducted via telephone to discuss their experience of living through the pandemic. A thematic analysis was conducted using a needs-based approach to detail the fundamental needs expressed by this population in relation to their mental health and quality of life during the pandemic.

Results

Three fundamental needs underpinned the experiences expressed by participants: the need to feel safe; particularly in relation to risk of contracting COVID-19 and their ongoing cancer monitoring; the need to feel connected; to the people, places, activities and practices of everyday life; and the need to make the most out of life; specifically in context of having already endured cancer and cancer treatment. Participant experiences are described in relation to how they impacted each of these three needs.

Conclusions

People living with and beyond cancer have past and ongoing experiences that make them vulnerable to adverse psychosocial reactions and outcomes. Support for this population needs to provide greater clarity of risk, clearer guidelines specific to their personal circumstances, and regular updates on scheduling of important follow up care and monitoring.
Societal discrimination and mental health among transgender athletes: a systematic review and Meta-analysis
Authors: Chan Alex Siu Wing , Choong Alston , Phang Kean Chang , Leung Lok Man , Tang Patrick Ming Kuen , Yan Elsie
Published: January 2024

Background

Discrimination and inequality have been identified as significant problems faced by transgender individuals in sports participation. However, uncertainties remain regarding the effectiveness of interventions aimed at promoting equality.

Objectives

This systematic review and meta-analysis aimed to examine the experiences of transgender athletes in sports, focusing on mental health issues and factors contributing to inequality among transgender and other sexual minorities.

Methods

The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched 10 electronic databases, including PubMed, Google Scholar, and Web of Science, to identify eligible studies published between 2005 and 2022. The search yielded 1430 articles, of which only 12 studies met the inclusion criteria for this review.

Results

The meta-analysis of the 12 studies included in this review revealed that transgender athletes faced social discrimination and inequality in sports participation, resulting in mental health problems and higher rates of suicide. From a cohort of 21,565 participants in the studies, 7152 (33%) were subjected to discrimination in sports participation and healthcare, with a rate of 0.61 (95% confidence interval [CI]: 0.35, 0.81). However, transgender athletes who felt welcomed and embraced by their respective teams accounted for 0.39 (95% CI: 0.19, 0.65). These results indicated significant differences between how transgender athletes are treated in healthcare settings and when participating in sports.

Conclusion

The study findings underscore the need for policies, cultural research, and interventions to address discrimination and inequality faced by transgender athletes in sports participation. Promoting equality and safeguarding the rights of transgender athletes can mitigate the risk of mental health problems and increase physical activity among sexual minorities.
Effects of school-based occupational therapy program for children with disabilities in elementary school in Korea: a case study
Authors: Jeong Eun-Hwa
Published: January 2024

Background

The purpose of this case study was to explore the effects of a school-based occupational therapy on children’s attention, school adaptation, sensory processing, and motor function for children in special classes in elementary school in Korea.

Case presentation

The subjects of this study were a 7-year-old boy with autism spectrum disorder and a 9-year-old girl with intellectual disability. The school-based occupational therapy program consisted of 10 sessions and was conducted once a week for an hour and a half. The program consisted of classroom activities, use of school facilities, emotional management, and activities based on sensory integration, and was conducted as individual and group programs according to sessions. As a result of the study, all improved when the pre- and post-scores of the two children’s attention assessment, school adjustment scale, sensory processing evaluation tool for the children in school and BOT-2-SF were compared.

Conclusions

Although the results from two cases cannot be generalized, the findings suggest the school-based occupational therapy program may help a positive effect on the school life of children with disabilities. Further investigation is necessary.
Analyses of the brown stain on the Parthenon Centaur head in Denmark
Authors: Rasmussen Kaare Lund , Rasmussen Bodil Bundgaard , Delbey Thomas , Bonaduce Ilaria , Kjeldsen Frank , Gorshkov Vladimir
Published: January 2024

In 1688 two sculptural fragments, a head of bearded man and a head of an unbearded youth, arrived in Copenhagen, sent from Athens as a gift to King Christian 5. They were placed in the Royal Kunstkammer, their provenance given as the Temple of Artemis in Ephesos, one of the Seven Wonders of the World. Almost a hundred and fifty years later, in the early 1820’s they were noticed and studied by two scholars independently visiting the Kunstkammer. However, both concluded that the two heads belonged to one of the metopes decorating the south side of the Parthenon temple on the Acropolis in Athens, showing fighting between Greeks and the mythical Centaurs, part man and part horse. In the 1830’s another sculptural fragment, a horse’s hoof, obtained through the German archaeologist and state antiquary of Greece, Ludwig Ross, reached Copenhagen. It was forwarded by the Danish consul to Athens, C.T. Falbe, as a gift to King Christian 8. The inventory reads: ‘… was found on the Acropolis near the Parthenon temple and is supposed to belong to one the Centaurs on the metopes.’ The present paper focuses solely on the head of the Centaur.

A brown stain was noticed on the Parthenon marbles as early as 1830 by the British Museum and has ever since eluded a deeper understanding of its genesis despite many investigations and attempts of analyses. A quite similar brown stain can be observed on the Centaur’s head in Copenhagen as well.

The present study reports analyses by LA-ICP-MS, SEM–EDX, µXRD, GC–MS, and LC–MS-MS, as well as optical microscopy of five small samples sequestered in 1999 from the Centaur head curated by the National Museum of Denmark. Our analyses show that the brown stain consists of two consecutively added surficial layers of the calcium oxalate minerals whewellite and weddellite. Despite a thorough search using proteomics, we have found no viable organic precursor material for the oxalates. Our results do not solve the mystery of the formation of the brown stain, but they do further qualify the structure and characterization of the brown stain.

Published: January 2024

Background

Porcine circovirus 2 (PCV-2) poses a significant economic threat for the swine industry, causing a range of diseases collectively referred to as porcine circovirus diseases (PCVDs). Despite PCV-2 vaccine effectiveness, the need for monitoring infectious pressure remains. PCV-2 coinfection with other pathogens like porcine reproductive and respiratory syndrome virus (PRRSV) can exacerbate disease severity and lead to PCV-2-systemic disease cases. Monitoring both PRRSV and PCV-2 in co-infected farms is crucial for an effective management and vaccination programs. The present cross-sectional study aimed to determine PCV-2 antibody levels in piglets at weaning and PCV-2 and PRRSV viremia in pooled serum samples at weaning (vaccination age) and at 6 and 9 weeks of age from a Spanish swine integration system in 2020 (48 farms) and in 2022 (28 out of the 48 analysed previously).

Results

The frequency of PCV-2 detection in pools of piglet sera was 2.1% (2020) and 7.1% (2022) at vaccination age but increased at the end of the nursery period (10.4% in 2020 and 39.3% in 2022) in both years. Co-infections between PCV-2 and PRRSV were detected in a significant proportion of PRRSV positive farms (15% in 2020, and 60% in 2022). PCV-2 antibody levels (ELISA S/P ratios) at weaning were lower in PCV-2 qPCR positive farms at different sampling time-points (0.361 in 2020 and 0.378 in 2022) compared to PCV-2 qPCR negative ones (0.587 in 2020 and 0.541 in 2022). The 28 farms tested both years were classified in four different epidemiological scenarios depending on their PCV-2 virological status. Those PCV-2 qPCR negative farms in 2020 that turned to be positive in 2022 had a statistically significant increase of PRRSV RT-qPCR detection and a PCV-2 antibody levels reduction, facts that were not observed in the rest of the scenarios.

Conclusion

This epidemiological study in farms from the same integration system determined the occurrence, in 2020 and in 2022, of PCV-2 and PRRSV infections in piglets during the nursery period by using pooled serum samples.
Exploring the critical factors affecting the adoption of blockchain: Taiwan’s banking industry
Authors: Lu Yi-Hsiang , Yeh Ching-Chiang , Kuo Yu-Mei
Published: January 2024

As an emerging technology, blockchain has recently gained attention in both academic and economic fields, but its adoption is not yet widespread in the banking sector in Taiwan. As academics have paid scant attention to this topic, this study determines the critical factors affecting blockchain adoption from the organizational perspective in the banking industry. We propose hybrid methods to fill the gap in the literature. First, we apply the technology-organization-environment framework as the basis and combine relevant factors as a framework to identify the relevant evaluation factors. Second, we propose a hybrid method that integrates the decision-making trial and evaluation laboratory (DEMATEL) with the evaluation based on distance from average solution (EDAS) approach and employs DEMATEL to measure the importance of the factors and alternatives to blockchain as ranked by the EDAS method. According to the ranking results, we identify the best preference among alternatives to blockchain. The results suggest that organizational and technological aspects are the main considerations to enhance and promote the effectiveness of blockchain adoption. This study suggests valuable strategies for stimulating blockchain adoption in the banking sector in Taiwan.
Leg length discrepancy before total knee arthroplasty is associated with increased complications and earlier time to revision
Authors: Mekkawy Kevin L. , Davis Ty , Sakalian Philip A. , Pino Alejandro E. , Corces Arturo , Roche Martin W.
Published: January 2024

Introduction

Leg length discrepancy (LLD) following total knee arthroplasty (TKA) is a common complaint, leading to decreased patient satisfaction. However, the effect of LLD diagnosis prior to TKA on outcomes and complications is not well defined. Thus, this study aimed to assess the effects that LLD has on rates of falls and implant complications, length of stay and readmissions, and implant survivorship following TKA.

Methods

A retrospective review of a private insurance claims database was conducted from 2010 to 2021. All cases of TKA and those with a diagnosis of leg length discrepancy were identified. Patients undergoing TKA with a diagnosis of LLD were matched to control patients 1:5 based on demographic and comorbidity profiles. Two-year fall rates and implant complications, lengths of stay, 90-day readmissions, and time to revision were compared between cohorts.

Results

A total of 1,378 LLD patients were matched to 6,889 control patients. The LLD group had significantly higher rates of falls, dislocation, mechanical loosening, periprosthetic fracture, and fibrosis when compared to the control group (all P < 0.01). Additionally, mean length of stay was significantly greater in the LLD group (4.9 days vs. 3.0 days, P < 0.001). There was no significant difference in 90-day readmission rates between groups (P = 0.178). Time to revision was significantly shorter in the LLD group (392 days vs. 928 days, P < 0.001).

Conclusions

Leg length discrepancy in patients undergoing TKA was associated with significantly increased fall risk, rates of implant complications, length of stay, and faster time to revision. The findings of this study may allow orthopedic surgeons to identify those patients at risk and allow for more educated patient counseling and operative planning.

Graphical Abstract
Another formulation of the fractional nonlinear Schrödinger equation
Authors: Paglan Paul André , Nguenang Jean Pierre
Published: January 2024

In this letter, we pave the way to establish the formulation of a non-trivial fractional Nonlinear Schrödinger (NLS) equation, which is different from the formulations known so far that consist in directly replacing the integer orders of the derivatives by non-integer ones. Thereafter, we set up some formulations, adapted to some particular physical cases, namely, the cases where the nonlinearity is stronger than the dispersion, in addition to one for which the dispersion strongly dominates the nonlinearity and also the case where the system displays a nonlinearity which is compensated with the dispersion. These formulations highlight the fact that the transition from a formal classical analysis to a fractional one could lead changes in the initial model of a given system. The research for solutions of the equations resulting from this study will undoubtedly reveal new phenomena in the different physical, biological and other systems described by the NLS equation.
Dropping the Bond or Dropping the Act?
Authors: Stewart Elizabeth
Published: January 2024

Throughout the United States, in 2020 and 2021, the Trump presidency and the covid-19 pandemic brought to light clashes in shared and lived realities among Americans and displayed them in jarring and perplexing scenarios—with a deadly toll. Strange martyrdoms and enacted oaths of loyalty to Trump in the form of people not getting vaccinated, not taking precautions, often attacking those who did, and throwing themselves away by (simply) dying are collective examples of what Jacques Lacan called the passage à l’acte and are symptoms of a profound decay of political culture. Radicalization of what Timothy Snyder has called “sadopopulism” and Chris Hedges has called “corporate totalitarianism” have led to a pervasive sense of impotence among large swaths of global populations who have been, and are being, abandoned and discarded, made victims of radical neglect, disappearance, and silencing—the covid martyrs a category among them.
On Our LastLeges
Authors: Goodrich Peter
Published: January 2024

Common law is predicated historically upon a sense of the common, of custom and use time out of mind. The legal tradition has its roots in a guild, an elite community whose common opinion and conversations provided the substance and sensibility of the normative. Remediation of law, meaning here the changing media of legal transmission, the imaginal turn in the streamed and viral relays of law and its enforcement, confront a monochrome and linear textual tradition, the regimentations of the page, with the fragmentary and anarchic optics of online platforms and social media bytes and nibbles. Increased online visibility, this essay argues, forces the guild to face up to an expanded commons, the diversity of colors, the heuristics of the eye, and the nuances of viewing.
Οι Έλληνες των Αυτοκρατόρων
Authors: Φάκκας Κωνσταντίνος
Published: January 2024

Η παρούσα διδακτορική διατριβή μελετά την επιρροή των ελληνικής προέλευσης στελεχών της αυτοκρατορικής διοίκησης επί της δυναστείας των Ιουλίων-Κλαυδίων (27 π.Χ. – 68 μ.Χ.), ιδιαίτερα στη χάραξη της αυτοκρατορικής πολιτικής, τη διαμόρφωση των αυτοκρατορικών διοικητικών θεσμών και την ανάδυση μιας ελληνικής διοικητικής ομάδας εξαρτημένης από τον αυτοκράτορα. Για τον σκοπό αυτό μελετήθηκαν σε προσωπογραφική βάση πάνω από τριακόσια άτομα για τα οποία γνωρίζουμε την ελληνική καταγωγή τους ή εκείνη προκύπτει από το ελληνικό cognomen τους, και τα οποία κατείχαν θέσεις στην αυτοκρατορική διοίκηση ή τις οποίες μπορούμε να υποθέσουμε λόγω των προσωπικών τους σχέσεων με τους αυτοκράτορες. Τον προσωπογραφικό κατάλογο ακολουθεί το συμπερασματικό τμήμα, το οποίο διαρθρώνεται σε τέσσερις ενότητες, όπου αναδεικνύονται η επιρροή των Ελλήνων εκείνων στη δημιουργία αυτοκρατορικών θέσεων και αξιωμάτων, η διαμόρφωση ομάδων συμφερόντων για την από κοινού εξυπηρέτηση των συμφερόντων τους, οι σχέσεις τους με τον ελληνικό κόσμο και, τέλος, η αξιοποίησή τους κατά ειδικότητες ικανοτήτων/γνώσεων. Από την ανάλυση των δεδομένων προκύπτει ότι οι Έλληνες των Ιουλίων-Κλαυδίων αυτοκρατόρων συνέβαλαν καθοριστικά στη διαμόρφωση των διοικητικών θεσμών της πρώιμης αυτοκρατορικής εποχής, όπως και στη δημιουργία μιας ελληνικής «διοικητικής αριστοκρατίας» στη Ρώμη και τις επαρχίες από την οποία προήλθαν πολλοί Έλληνες συγκλητικοί και ιππείς κατά τους πρώτους δύο μεταχριστιανικούς αιώνες.
Από το πολιτικό τραγούδι στα "σκυλάδικα"
Authors: Κανέλλος Γεώργιος
Published: January 2024

H παρούσα διδακτορική διατριβή πραγματεύεται τις διαδικασίες συγκρότησης της «λαϊκής» κοινωνικής και πολιτιστικής ταυτότητας στην Ελλάδα κατά την περίοδο της πρώιμης και ύστερης μεταπολιτευτικής περιόδου, εστιάζοντας συγκεκριμένα στην περίοδο από το 1974 έως το 1989. Ειδικότερα, στοχεύει στη διερεύνηση των μεταβολών που συντελούνται στο χώρο της λαϊκής κουλτούρας κατά την περίοδο αυτή, με πιο σημαντική τη μετάβαση από την περίοδο κυριαρχίας του πολιτικού τραγουδιού στο χρονικό διάστημα μεταξύ 1974 και 1977, έως τη σταδιακή ανάδυση της σκηνής του «σκυλάδικου» και της «μεγάλης πίστας» κατά τη δεκαετία του 1980. Παράλληλα, η έρευνα θα στραφεί στις κεντρικότερες πτυχές αυτών των μεταβολών, όπως η απενοχοποίηση του στοιχείου του «γλεντιού», μια τάση που βρίσκεται σε αντίθεση με τα ειωθότα της προδικτατορικής περιόδου. Επιπροσθέτως, η διατριβή εστιάζει στην πρόσληψη των μεταβολών αυτών από ολόκληρο το πολιτικό και κομματικό φάσμα. Πιο συγκεκριμένα, θα εξεταστούν οι διαφορετικές στρατηγικές προσλήψης της λαϊκής μουσικής από τα δύο μεγάλα κόμματα, το ΠΑΣΟΚ και τη Νέα Δημοκρατία, από τα δύο Κομμουνιστικά Κόμματα, καθώς και από ερευνητές της λαϊκής μουσικής, όπως οι αρθρογράφοι του μουσικού περιοδικού Ντέφι. Αναφορικά με το ΠΑΣΟΚ, η πρόσληψή του παρουσιάζει ιδιαίτερο ενδιαφέρον, καθώς, ως κυβερνόν κόμμα κατά το μεγαλύτερο μέρος της δεκαετίας του 1980, συνέβαλε ποικιλοτρόπως στην αναγνώριση του λαϊκού τραγουδιού, διακρίνοντας εγκαίρως τις δυνατότητες πολιτικής αξιοποίησης της λαϊκής μουσικής. Σε αυτή την κατεύθυνση, θα αξιοποιηθούν παραθέματα από τον Τύπο και από κομματικά αρχεία.

Αυτή η διατριβή με τίτλο Εφαρμογές Μικροοικονομικής στη Θεωρία Διεθνούς Εμπορίου στοχεύει στην εξέταση του ρόλου της κρατικής παρέμβασης σε μια σειρά πιθανών σεναρίων σε επίπεδο Διεθνούς Εμπορίου. Η Εισαγωγή παρέχει μια γενική επισκόπηση αυτής της εργασίας. Το Κεφάλαιο 1 παρέχει μια λύση στο πρόβλημα αναποτελεσματικότητας που προκύπτει όταν εισάγεται ασυμμετρία κόστους σε ένα στρατηγικό εμπορικό πλαίσιο, όταν τα ολιγοπώλια ανταγωνίζονται σε τρίτη αγορά. Ένας διαγωνισμός λόμπι χρησιμοποιείται για τον προσδιορισμό της οικονομικά αποδοτικότερης επιχείρησης, η οποία κατόπιν λαμβάνει επιδότηση a la Brander και Spencer και εξάγει στη αγορά της χώρας τρία. Ευκαιρίες βελτίωσης της κοινωνικής ευημερίας προκύπτουν από αυτή την παρέμβαση. Το Κεφάλαιο 2 αναλύει όλες τις πιθανότητες να προκύψουν συμφωνίες συνεργασίας μεταξύ επιχειρήσεων και φορέων χάραξης πολιτικής στο πλαίσιο του Στρατηγικού Εμπορίου, όταν λειτουργούν μονοπώλια στις δύο χώρες παραγωγής. Τα μέτρα που χρησιμοποιούνται από τις κυβερνήσεις και τα επίπεδα κατανάλωσης στις τρεις εμπλεκόμενες χώρες θα καθορίσουν το πιθανό αποτέλεσμα τέτοιων συστημάτων. Το Κεφάλαιο 3, εξετάζει τον ρόλο της κυβέρνησης στην παροχή κινήτρων σε μια ξένη εταιρεία που στοχεύει να εισέλθει στην αγορά της, με τέτοιο τρόπο ώστε να αλλάξει τον βέλτιστο τρόπο εισόδου της, εάν αυτός διαφέρει από εκείνον που ενισχύει την κοινωνική ευημερία και άρα κυβερνητικά προτιμώμενο τρόπο. Τα ευρήματα δείχνουν ότι υπάρχει πιθανότητα να γίνουν αποδεκτά μέτρα κινήτρων αλλαγής τρόπου λειτουργίας, ιδιαίτερα σε ένα πλαίσιο μικρής αγοράς. Το Κεφάλαιο 4 παρέχει ένα συνολικό συμπέρασμα της ανάλυσης.

Στην παρούσα εργασία εξετάζουμε το κρυπτοσύστημα NTRU και την ψηφιακή υπογραφή (EC)DSA, και παρουσιάζουμε καινούργιες επιθέσεις που βασίζονται στα δικτυωτά. Αρχικά παρουσιάζουμε τα δύο συστήματα και σχολιάζουμε τις προηγούμενες επιθέσεις σε αυτά. Έπειτα παρουσιάζουμε τα πιο σημαντικά αποτελέσματα από την θεωρία των δικτυωτών. Στην συνέχεια περιγράφουμε μία επίθεση στην ψηφιακή υπογραφή (EC)DSA, η οποία ανάγει το πρόβλημα της εύρεσης του μυστικού κλειδιού στο CVP για ένα συγκεκριμένο δικτυωτό, και στην συνέχεια εφαρμόζουμε τον αλγόριθμο του Babai. Συνεχίζοντας με το (EC)DSA, παρουσιάζουμε μία επίθεση η οποία χρησιμοποιεί τον αλγόριθμο απαρίθμησης του Kannan παίρνοντας ως δεδομένο ότι κάποια από τα εφήμερα κλειδιά έχουν κοινά bits σε κάποιες συγκεκριμένες θέσεις. Η τελεταία επίθεση στο (EC)DSA, είναι μία ειδική περίπτωση όπου τα κλειδιά είναι αρκετά μικρά. Παρουσιάζουμε έναν αλγόριθμο σε αυτή την κατεύθυνση και δίνουμε δύο εφαρμογές όπου η μία αφορά το bitcoin. Τέλος μελετάμε το κρυπτοσύστημα NTRU και δείχνουμε ότι το πρόβλημα της εύρεσης του καθαρού κειμένου ανάγεται στο CVP για ένα συγκεκριμένο δικτυωτό. ΄Επειτα εφαρμόζοντας τον αλγόριθμο του Babai βρίσκουμε το καθαρό κείμενο. Σε όλες τις επιθέσεις παρουσιάζουμε τα πειραματικά δεδομένα για να δείξουμε την αποτελεσματικότητά τους.

Οι διατάξεις του ιωβηλαίου έτους και το κοσμοείδωλο που ο συγκεκριμένος θεσμός οραματιζόταν σχετικά με την κοινωνική και θρησκευτική αποκατάσταση συνθέτουν στο χώρο της ερμηνείας της Αγίας Γραφής μια ομιχλώδη εικόνα που εδώ και καιρό ζητά απεγνωσμένα να ξεκαθαρισθεί. Από την άλλη, εξίσου ομιχλώδης είναι και η παρουσία της μυστηριώδους προσωπικότητας του Μελχισεδέκ, ο οποίος στη γραφίδα των βιβλικών συγγραφέων εμφανίζεται από το πουθενά και εξαφανίζεται αμέσως μόλις ολοκληρώσει το έργο του.

Midwives as Adult Educators: An investigation of midwives’ perceptions about the educational dimension of their profession
Authors: Papageorgiou Ira , Kostourou Eleni
Published: January 2024

This article deals with the educational dimension of Midwifery, as manifested in the context of perinatal education programmes in Greece. Despite the internationally recognized value of childbirth education in reducing perinatal mortality and morbidity, and despite the rich activity of midwives in terms of perinatal education, their role as adult educators has received limited scientific attention and support. The purpose of this study is to investigate whether and to what extent midwives teaching in perinatal programmes perceive their role as educators, as well as whether and in what way they are prepared for this role. It also investigates whether and what form of training midwives receive to their role in perinatal education. The study followed the specifications of qualitative design and data was collected through in-depth semi-structured interviews with twelve (12) midwives - trainers in perinatal education, as well as with eight (8) women and men who have participated in childbirth classes in Greece. The findings highlight the need to further support midwives in their educational role and to enhance their educational practice by integrating the principles of Adult Education.

Given that early adolescence is a dynamic and vulnerable developmental period, it is important to examine factors that promote adolescents’ individual development and, more specifically, the satisfaction of psychological needs within the framework of self-determination theory. In a two-wave longitudinal sample (N = 218) of Greek adolescents (eighth grade in autumn 2020 and ninth grade in autumn 2021), we used structural equation modeling to determine which individual and social factors longitudinally predict autonomy, competence, and relatedness. The examination of these psychological needs is regarded as a necessary step in designing school-based prevention and intervention programs for adolescents. Individual factors, such as self-esteem, self-efficacy, and depression or anxiety, foster self-determination through social factors, such as recognition and support from teacher and parents, and social resources. Adolescents with a migration background showed lower levels of social factors. The model was gender invariant and indicated that social agents (teachers and parents) and social resources predict a very large proportion of variance in early adolescents’ individual development. These findings support the view that early adolescents’ development depends on social factors through the satisfaction of psychological needs.
The role of working memory in the comprehension of syntactically complex sentences in children with and without developmental language disorder: A literature review
Authors: Karavasilis Gavriil , Diakogiorgi Kleopatra , Papadopoulou Despoina
Published: January 2024

Working memory (WΜ) components are investigated as correlates of complex sentence comprehension (cSC) in children, under the consideration of WM as a cognitive system of limited capacity. The present study aims to investigate the relationship between WM components and cSC in children of typical language development (TLD) as well as in children with Developmental Language Disorder (DLD), by systematically reviewing relevant studies. First, different tasks that are used to assess three distinct WM components are presented and task purity considerations on each of them are taken into account. Second, syntactically complex sentence types that are considered to constrain the already limited resources of WM are presented. Then, the systematic methods of the PRISMA-P protocol are followed. Based on them, six databases were thoroughly searched. After an initial screening stage and a final evaluation stage, twenty-eight studies were found to meet the inclusion criteria. Narrative synthesis was performed on the included studies. In TLD children, results on the role of verbal short-term memory (vST) and verbal working memory (vWM) in cSC are inconclusive, either supporting or questioning the capacity-limit approach. In DLD children, verbal working memory (vWM) has an important effect on cSC, rather than verbal short-term memory (vSTM). This suggests that a processing-execution component is important in DLD children’s cSC. For both children groups, a component serving as an interface between vSTM/vWM and long-term memory (vSTM/vWM-LTM) seems to play an important role; however, it is greatly understudied. Based on the results, future research directions and educational implications are suggested.
Executive functions, listening comprehension, and metacognitive processes in childhood: Developmental profiles
Authors: Bablekou Zoe , Chrysochoou Elisavet , Kazi Smaragda
Published: January 2024

Despite the established interplay between executive functioning and metacognition, evidence remains limited regarding children’s metacognitive monitoring in the form of offline performance estimates of their executive efficiency. Moreover, we know little about the relations among listening comprehension, executive functions, and metalinguistic awareness in childhood. The present study constitutes a first exploration of developmental profiles related to executive functioning, listening comprehension, and corresponding metacognitive-metacomprehension monitoring in periods marking their emergence and interplay. Participants were 95 preschoolers (Mage 5.5), and 109 second graders (Mage = 7.5). Executive function (i.e., working memory, inhibition, and cognitive flexibility) and a listening comprehension task were administered, along with offline performance estimates following completion of each task.   Fluid and crystalized intelligence tests were also administered. Cluster analyses were applied. Across ages, one cluster was characterized by lower cognitive performance, but overestimated metacognitive judgements, while a second cluster demonstrated the exact opposite pattern. Older children performed at a higher cognitive level. Yet, metacognitive monitoring did not improve as a function of age, in the sense that a third, metacognitively accurate cluster did not emerge among second graders. Working memory and listening comprehension, along with their metacognitive-metacomprehension estimates, demonstrated the greatest contribution to the cluster solution in both age groups. The inhibition-metainhibition measures proved stronger profile determinants in the older group. The fluid intelligence measure showed a reduced contribution with age and vocabulary proved to be a weak and insignificant distinctive characteristic of the profiles emerging among preschoolers and second graders, respectively. Findings are discussed in relation to relevant research data and theoretical suggestions regarding cognitive and metacognitive development.
Metacognitive phenomena during human–Internet interactions
Authors: Sidiropoulou Eleni , Metallidou Panayiota
Published: January 2024

External information systems often serve as an extended cognitive system and are usually conceived as expansions of the capacity of human cognition. However, the boundaries between our own mind and a powerful cloud mind, like the Internet, are increasingly blurry. This paper discusses recent empirical evidence of various metacognitive phenomena taking place while searching for information on the Internet, against the backdrop of the theory of transactive memory systems and the theory of cognitive offloading. The discussion focuses on the ways our cognitive systems maneuver and adapt their responses to the medium of the Internet by examining its effects on the metacognitive evaluations of oneself as a knower, the novel metacognitive experience of the feeling of findability, and how our metamemory judgments are affected. The conclusion proposes directions for future research and a better understanding of our interaction with the Internet.

Authors: A Patil Satish , R Patil Amit , Chougule V N , Sanamdikar S T
Published: January 2024

The primary focus of this study was the development of a solar panel cleaning machine intended for the maintenance of photovoltaic solar panels after their installation. The study also encompassed detailed analysis of this machine. The accumulation of dust particles on solar panels presents a significant challenge, as it jeopardizes the optimal functionality of these panels. By obstructing crucial sunlight, dust diminishes the panels' electricity production capacity, consequently reducing overall efficiency. Moreover, this dust accumulation poses a threat to the integral electrical components of the panels, potentially causing harm to the embedded silicon wafers through overheating if left unaddressed. This situation escalates the necessity for post-installation maintenance and escalates associated repair costs. In response to these challenges, a novel automated mechanism for cleaning solar panels is introduced in this paper, effectively eliminating dust particles. The analytical findings strongly indicate that consistent and periodic cleaning of panels can uphold a stable rate of electricity generation within the power production system. This innovative system design empowers users to effortlessly operate the machine in less time, all the while delivering superior cleaning performance when compared to conventional manual methods. To establish a competitive edge in the market, it is imperative that the proposed system presents a cost-effective solution, evaluated in relation to the number of panels cleaned. Consequently, for the purpose of testing the proposed system, a solar installation was meticulously designed and implemented at PDEA’s College of Engineering in Manjari, (Bk.) Pune, Maharashtra, India. This location was deliberately selected as the experimental site to facilitate comprehensive investigations of the requisite design metrics. The prototype was subsequently simulated within this real-world system. This cleaning system utilizes high-quality microfiber cloth to effectively remove dust from panel surfaces without the need for water, making it suitable for arid areas. Additionally, provisions have been included for a water sprinkler to address stubborn stains like bird droppings that cannot be removed solely with the cloth. The overall impact of this mechanism will result in an increased rated power output from the panels, which had previously been compromised due to the mentioned issues.
Optimizing CI Engine Ethanol Fuel Induction Techniques Using the AHP-PROMETHEE II Hybrid Decision Model
Authors: Shaikh Mazar A , R Patel Vimal
Published: January 2024

Ethanol along with nanoparticles stands out as a promising alternative in the pursuit of environmentally sustainable fuel options, offering a potential solution to the dual challenge of curbing NOx and PM/soot emissions while optimizing engine performance in compliance with stringent pollution regulations for compression ignition (CI) engines. The research study aims to optimize ethanol fuel induction techniques for CI engines. It utilizes a hybrid decision-making approach that integrates the analytic hierarchy process- AHP- for problem structuring and the derivation of preference weights. Subsequently, the preference ranking organization method for enrichment evaluations-PROMETHEE II is applied to assess and rank the existing alternatives. The study entails a methodical assessment of diverse ethanol induction methods across varying engine load ranges, considering multiple criteria including engine performance, emissions, combustion behavior, and exhaust after-treatment efficiency. Hybrid AHP-PROMETHEE II model provides criteria weights and ranks ethanol induction techniques and fuel blends across low, medium, and high engine loads for decision-making. It ensures that the method chosen aligns with goals, such as reducing NOx and soot emissions, optimizing engine performance, enhancing combustion, and minimizing exhaust after-treatment costs for CI engines. According to the research findings, the hybrid AHP-PROMETHEE II model identifies the CI engine operating at medium load with ethanol blending (DE10) and without the use of nanoparticles as the preferred choice. Additionally, AHP-PROMETHEE II (AHP derived criteria weights) and PROMETHEE II (direct rating derived criteria weights) models, suggested DE10 with nanoparticle (DE10_NP) using blending technique at low load and combined blending-fumigation technique with nanoparticles at high load. However, at medium load, PROMETHEE II recommends DE10_NP, while AHP-PROMETHEE II recommends DE10 blending technique. To assess the performance and reliability of this model, the consistency ratio and Spearman's rank correlation coefficient indices were computed, yielding values of 0.05 and 0.59, respectively. Both indices fall below the predetermined threshold limits, indicating a high level of consistency of the model.

Published: January 2024

Frequent water-borne disease outbreaks affecting human health have been reported in district Solan, which is a rapidly industrialing region of Himachal Pradesh, a northern state of India. For ascertaining the cause, microbiological assessment of drinking groundwater sources of the region was undertaken. For this, thermotolerant coliform study and genome typing were undertaken. Multiple tube fermentation technique was employed in selected five sources to detect thermotolerant coliforms during the seasons of monsoon and post-monsoon in the years 2018-19. Thermotolerant coliforms varied in Most Probable Number from 2-34 per 100 ml water indicating contaminated water sources, densities being significantly more in monsoon months (p< 0.05). Four different coliform morphotypes were obtained from all the sources on Eosin Methylene Blue plates. Of these, the only strain, designated as Nalagarh Water Strain (NGW), was recovered from all sources, suggesting its prevalence. Based upon biochemical and morphological attributes, the strain was recognized as Escherichia coli. Conversely, molecular characterization (16S rRNA ribotyping) identified it as Raoultella planticola (GenBank accession No. MK318824). The strain was deposited in a National Culture Collection Centre, National Centre for Microbial Resources, Pune, Maharashtra (India) with deposition accession number MCC 4064 for future utility in public research activities. Microbiological assessment evinced contaminated drinking water sources, probably causing diarrhoeal diseases. 16S rRNA ribotyping assisted in correct identification of the microorganism.

The Pariyej Community Reservoir (PCR) is a freshwater reservoir in the Kheda district of Gujarat State, India. The PCR is also listed in Asian Directory of Wetlands. It is an important water storage reservoir; falls in the 4-B Gujarat Rajwara region of Central Gujarat, India. The present study was carried out for the period of one year (March, 2021 to February, 2022) to assess the status of avian diversity in terms of its species richness, abundance, and density. 116 bird species from 20 orders, 51 families, and 100 genera were documented. 75 species (64.4%) were resident, whereas 41 (35.3%) were migratory or seasonal. With respect to abundance, 41species (35.34%) were abundant, 39 species (33.6%) common, and 36 rare species (31.0%). The maximum total abundance (1707 individuals) was found at Site 1 in winter season with mean abundance of 427 individuals, total density (114 individuals/sq.km)and mean density (29 individuals/sq.km). The minimum total abundance (288 individuals) was recorded at Site2 in monsoon season with mean abundance of 72 individuals, total density (19individuals/sq.km) and mean density (5 individuals/sq.km).The present investigation reflects the good species richness of avian specieswith respect to order: family: genera: species ratioi.e., 1: 2.55: 5.0: 5.8. This indicates the flourishing harboring capability of PCR during peak winter period, which could be due to sustenance of rich biotic elements. The PCR has been declared as Sanctum sanctorumfor the refuge of migratory as well as local migrant birds, which is proved to be a wetland of national importance.
