Authors: Imeraj Zamira , Veseli (Bego) Denisa , Pirushi Rudina
Published: June 2022

Introduction: Nurses spend more time with patients than any other member of the healthcare team. They play a critical, active and very important part in controlling cancer patients' pain and alleviating suffering. This study aimed to explore current nursing practices in the oncology hospital and the level of knowledge they possess about pain and its management in clinical settings.
Methods: This is a transversal type study developed on the basis of cluster sampling type on nurses in the Oncology Hospital, Tirana. The study was conducted in the period 2016-2018 and the sample consisted of 119 nurses.
Results: In total, 119 questionnaires were completed by oncology hospital nurses. Regarding the gender of was seen a predominance of women nurses compared to men 78.15% and 21.85% respectively. Nurses between the age 30 until to 39 years old were 34.4% of participants. Nurses of different gender, education level, and place of birth showed statistically significant difference. Only 23.5 % of nurses had pain training and education, and less than half of nurses (43.7%) had 5-10 years in oncology hospital. In this study, knowledge and practice of nurse’s participant on non-and pharmacological pain management were more than 55%. Related to the pain assessment 36.1% were based on the information provided by the patients, while 31.1% of nurses had used the visual analogue scale for pain assessment. According to the ways of pain management, almost 76.5% of nurses think that the best ways of pain management were pharmacology and 71.4% selected opioid analgesic medication while 28.6% selected non-opioid analgesic medication. Contacting the physician for the prescription of opioids was cited as the main delaying process by 43.7% of participants.
Conclusions: The results of the study demonstrated that the nurses had limited knowledge of pain management, because of non-training courses for consequence all of it was associated with poor attitude toward pain management. Most of them did not have formal training in pain management either at the local level. Many of them are familiar with oral route of administration of opioids but still the logistics of administration is not clear to them. Nowadays training and education in pain management is a necessity for medical staff especially for nurses because the adequate knowledge is vital in the provision of quality pain management to patients.

Published: June 2022

BACKGROUND: This meta-analysis compared transforaminal interbody fusion (TLIF) and oblique lumbar interbody fusion (OLIF) techniques for degenerative lumbar spondylolisthesis.

AIM: The aim is to evaluate Oswestry Disability Index (ODI), Japanese Orthopedic Association Back Pain Evaluation Questionnaire, visual analog scale improvement for back and leg pain, disc height, slipped percentage, blood loss, surgical time, and complication rates in both groups.

METHODS: A systematic literature search was carried out to obtain a study that compared OLIF and TLIF for degenerative lumbar spondylolisthesis. A literature search was performed using PubMed, Scopus, EuropePMC, and EBSCOHost. While the intervention was the OLIF technique, the control was the TLIF technique. The primary outcome was clinical outcome (ODI, Japanese Orthopaedic Association Back Pain Evaluation Questionnaire [JOABPEQ], visual analog scale [VAS] improvement for back, and leg pain). The Newcastle-Ottawa Scale was used to assess the quality of the studies.

RESULTS: Total of 384 patients from four studies were included in this study. OLIF group was better than TLIF group in terms of disc height, slipped percentage, and blood loss. ODI, JOABPEQ, VAS improvement for back pain (standardized mean difference [SMD] 0.06 [−0.18, 0.29], p = 0.63, I2 = 0%, p = 0.87) and leg pain (SMD 0.12 [−0.36, 0.60], p = 0.63, I2 = 74%, p = 0.02), surgical time, and complication rates were similar in both groups.

CONCLUSION: OLIF technique was better than TLIF technique in terms of radiologic outcome and surgical blood loss. Both techniques showed similar outcomes in clinical outcome, complication, and surgical time.

Published: June 2022

The characteristics of the leaf epidermis have proven to be useful criteria to support taxonomic studies within Fabaceae. However, there are few systematic studies on the taxonomic significance of leaf epidermis of Oxytropis DC. Here, we used light and scanning electron microscopy to investigate leaf epidermal characteristics of 18 species of genus Oxytropis from the Northeastern Margin of Qinghai-Tibet Plateau. Our examination showed two main types of leaf epidermal cells: polygonal and irregular, and four different patterns of anticlinal walls: straight-arched, sinuolate, undulate, and sinuate. All species studied possess anomocytic stomata. Two trichome shapes were identified: strip-like trichomes, that were present only in O. ciliata, and cylindrical trichomes, present in all other species. Epidermal cell shape and anticlinal wall pattern were constant within species and are useful for species delimitation within genus Oxytropis, when combined with other macroscopic traits. The shape of trichomes can be useful for distinguishing O. ciliata from the other investigated species. Stomatal type was the same within the genus and may be used to elaborate the phylogenetic relationships between genera in combination with data on stomata from other genera. Cluster analysis results were largely consistent with the classification of species and sections based on macro morphological data, indicating that foliar epidermis characteristics of Oxytropis can be used as markers for taxonomic identification at the infrageneric classification level. Lastly, our results support the delineation of the section Leucopodia as an independent section but do not support the merging of section Gobicola into section Baicalia.

Published: June 2022

The molecular and morphological studies carried out within the scope of this study revealed that the scrapers, known as the Mesopotamian group, belong to a different genus. The Paracapoetagen. nov., from the Mesopotomia and Levant, is distinguished from Capoeta and Luciobarbus species by the presence of a strong ligament between the base of the last simple and the first branched rays of the dorsal-fin (vs. no or a very weak ligament). The Paracapoeta further differs from Capoeta by the last simple dorsal-fin ray strongly ossified in adult specimens (more than 75%, vs. less than 75%). The Paracapoeta further differs from Luciobarbus by the lower lip with horny layer (vs. fleshy lips). The molecular phylogeny based on the combined dataset (COI + Cytb, 1312 bp.) showed that the genus Paracapoeta was recovered from the other groups in the subfamily Barbinae with high bootstrap and posterior probability values (BP: 94%, PP: 0.96). Also, Paracapoeta and Capoeta are well differentiated by an average genetic distance of 8.02±0.78%. The morphological and molecular findings have largely overlapped each other. Besides, Capoeta turani is treated as a synonym of Capoeta erhani.

Published: June 2022

Cet article rend compte d’une recherche portant sur le processus d’institutionnalisation de l’accouchement par césarienne au Brésil et en France, en adoptant une démarche socio-clinique institutionnelle. L’éducation et la santé sont considérées comme des institutions qui déterminent les pratiques professionnelles materno-infan-tiles. Le taux très élevé de césarienne au Brésil interroge les logiques dominantes et les rapports de pouvoir dans le système de santé. Suite à ces constats, il s’agit d’envisager des modalités de formation initiale et continue susceptibles de transformer les pratiques par l’analyse des implications des professionnels dans une institutionnalisation morbide et aliénante.
L’expérience du terrain

Published: June 2022

Cet échange est le fruit d’une rencontre avec François Laplantine, professeur honoraire à l’université Lumière-Lyon 2 où il a fondé le département d’anthropologie. Ses recherches conduites en Afrique, au Brésil, et plus récemment au Japon, interrogent les voies et les modes de production de connaissances sur l’humain. En convoquant tour à tour les apports de l’anthropologie, de la philosophie, de la psychanalyse ou de l’expérimentation artistique, l’auteur invite à interroger la question du corps, du sensible, de l’intime, et de la présence du chercheur dans ce qu’il nomme l’« expérience du terrain ».
L’enquête qualitative et le point de vue des acteurs
Authors: Olivier de Sardan Jean-Pierre
Published: June 2022

En éducation comme dans bien d’autres domaines, les indicateurs quantitatifs tiennent le haut du pavé. Le registre de la preuve légitime repose essentiellement sur des statistiques, sondages, taux, seuils, données chiffrées et agrégées… Pourtant, de nombreux éléments décisifs pour comprendre les processus à l’œuvre restent inaccessibles par ces procédés. Recueillir le point de vue des acteurs, observer leurs interactions, analyser les routines ou déchiffrer les tensions, tout cela implique le recours à des méthodes qualitatives. L’enquête qualitative implique que le chercheur produise lui-même ses données grâce à son immersion personnelle dans un ou plusieurs sites, au plus près du quotidien, au cœur des contextes locaux dans lesquelles les politiques éducatives prennent place, et où elles sont soumises aux réactions, adaptations et contournements des acteurs concernés.
Qu’apporte le terrain du géographe aux sciences de l’éducation et de la formation ?
Authors: Barthes Angela
Published: June 2022

La géographie est une science territorialisée qui repose sur la pratique de terrains : le géographe rapporte ce qui s’observe et le contextualise pour transformer l’observable ponctuel en une analyse d’ensemble. il quantifie le terrain pour objectiver et comparer. il remonte dans le passé pour proposer une prospective. il parcourt les catégories socio-spatiales pour les caractériser et les mettre en relation. L’article illustre cette perspective par une étude de cas impliquant des épistémologies des sciences de l’éducation et de la formation et une pratique géographique de terrain. il montre comment la pluridisciplinarité permet une interaction conceptuelle fructueuse et comment, en partant de problématiques socioprofessionnelles en éducation et formation, ce qui est défini comme un terrain d’étude peut être réexploré.
Faire trembler le tremblement
Authors: Damian Jérémy
Published: June 2022

Fabriquer des visions du futur est une activité qui, alimentée par la crise écologique, occupe de plus en plus d’acteurs et d’experts. Chaque expertise produit un type de récit caractéristique qui modèle les futurs et sculpte les imaginaires. La collapsologie a ainsi imposé massivement le motif de l’effondrement. Mais que se passerait-il si au motif de l’effondrement était substitué celui du tremblement ? Le motif du tremblement trace un plan de continuité entre des corps très hétérogènes (corps terrestre, humain, vivant, social, politique…). À la logique verticale de l’effondrement, il propose une oscillation horizontale à l’intérieur des limites, scénarios, programmes préétablis. Tous et toutes des corps tremblants !

Authors: Ginovyan Mikayel , Andreoletti Pierre , Cherkaoui-Malki Mustapha , Sahakyan Naira
Published: June 2022

In the presented work, we aimed to investigate the antioxidant and possible neuroprotective capacity of extract of the aerial parts of Hypericum alpestre, found in high altitude Armenian landscape. The neuroprotective activity was evaluated using BV-2 wild type (WT) cells and acyl-CoA oxidase 1 (ACOX1) deficient (Acox1-/-) microglial cell lines. In the chemical-based tests, H. alpestre extract showed high antioxidant activity, which was maintained even after heat treatment at 121 °C for 30 min. MTT test showed that the sub-cytotoxic concentration of investigated extracts for both microglial cell lines was 40 µg/mL. There were no significant changes in catalase activity during all period of treatment in both cell lines, meanwhile, SOD activity increased (up to 30%) in WT cells during the 48 h treatment. Increase of SOD activity (up to 50%) in Acox-/- cells was observed under the 24 h treatment. Significant modulation in activity of palmitoyl-CoA oxidase 1 was noticed only during the 48 h treatment of WT microglial cells. These results evidenced the pro-oxidant activity of the investigated extract. This finding can serve as a basis for further evaluation of plant extracts influence on cancer cell lines.
Analyzing the relationship between the vitamin D deficiency and COVID-19 mortality rate and modeling the time-delay interactions between body's immune healthy cells, infected cells, and virus particles with the effect of vitamin D levels
Authors: Pham Hoang
Published: June 2022

This paper presents some recent views on the aspects of vitamin D levels in relation to the COVID-19 infections and analyzes the relationship between the prevalence rates of vitamin D deficiency and COVID-19 death rates per million of various countries in Europe and Asia using the data from the PubMed database. The paper also discusses a new mathematical model of time-delay interactions between the body's immune healthy cells, infected cells, and virus particles with the effect of vitamin D levels. The model can be used to monitor the timely progression of healthy immune cells with the effects of the levels of vitamin D and probiotics supplement. It also can help to predict when the infected cells and virus particles free state can ever be reached as time progresses. The consideration of the time delay in the modeling due to effects of the infected cells or virus particles and the growth of healthy cells is also an important factor that can significantly change the outcomes of the body's immune cells as well as the infections.
Estimating relative generation times and reproduction numbers of Omicron BA.1 and BA.2 with respect to Delta variant in Denmark
Authors: Ito Kimihito , Piantham Chayada , Nishiura Hiroshi
Published: June 2022

The Omicron variant spreads fastest as ever among the severe acute respiratory syndrome coronaviruses 2 (SARS-CoV-2) we had so far. The BA.1 and BA.2 sublineages of Omicron are circulating worldwide and it is urgent to evaluate the transmission advantages of these sublineages. Using a mathematical model describing trajectories of variant frequencies that assumes a constant ratio in mean generation times and a constant ratio in effective reproduction numbers among variants, trajectories of variant frequencies in Denmark from November 22, 2021 to February 26, 2022 were analyzed. We found that the mean generation time of Omicron BA.1 is 0.44–0.46 times that of Delta and the effective reproduction number of Omicron BA.1 is 1.88–2.19 times larger than Delta under the epidemiological conditions at the time. We also found that the mean generation time of Omicron BA.2 is 0.76–0.80 times that of BA.1 and the effective reproduction number of Omicron BA.2 is 1.25–1.27 times larger than Omicron BA.1. These estimates on the ratio of mean generation times and the ratio of effective reproduction numbers have epidemiologically important implications. The contact tracing for Omicron BA.2 infections must be done more quickly than that for BA.1 to stop further infections by quarantine. In the Danish population, the control measures against Omicron BA.2 need to reduce 20–21% of additional contacts compared to that against BA.1.

Published: June 2022

This study presents an analysis of M. tuberculosis growth data obtained using the BACTEC MGIT 960 system and respective mathematical models. The system is based on the detection of a decrease in oxygen level in the broth due to the bacterial respiration. It is shown that recordings sampled with a 1 hour rate provide an opportunity to distinguish between the oxygen consumption of growing cells and active cells division when the density of micro-organisms is sufficient to enter into the synchronized division mode. More specifically, the growth of culture is continuous only with large initial dilutions; otherwise, there are jumps between different growth stages with a time interval of 13–15 h. The combination of the oxygen-quenching kinetics for an analytic reagent and the population growth kinetics resulted in a mathematical model, which consists of mixing Verhulst's and Gompertz's models. The parameters of such mixing and switching between the models' prevalences are discussed with respect to oxygen uptake reactions reflected in the changes in the experimentally registered fluorescence level.
Tourism carrying capacity in the municipalities of Tolmin, Kobarid and Komen
Authors: Jurinčič Igor
Published: June 2022

The study of tourism carrying capacity in the municipalities of Tolmin, Kobarid and Komen has shown that the infrastructural and economic carrying capacity is the most problematic, as most indicator limits are already exceeded in the summer season. The most favourable is the spatial-ecological carrying capacity, where none of the studied indicator limits were exceeded. The results of the carrying capacity assessment for tourism in these municipalities should not be used as a tool to restrict tourism development, but rather as expert recommendations to promote more sustainable tourism development. Infrastructure identified as deficient cannot be improved immediately. Improvements require large financial investments that municipalities are not able to ensure quickly. We need a tourism development strategy that, in addition to all the necessary improvements, comprehensively addresses the problems that municipalities face from overtourism, especially during the high season.

Authors: Mukhtarkyzy Kaussar , Abildinova Gulmira , Sayakov Olzhas
Published: June 2022

Augmented reality (AR) practices and technologies have the potential to redefine aspects of education, including laboratory work. AR tools provide an easy and cost-effective solution for helping students overcome the constraints imposed by online education. The article demonstrates the use of an AR application in Physics lessons at the Lyceum School No. 85 in Nur-Sultan city, Kazakhstan. The AR application includes an interactive 3D model of circuits and circuit components that can be viewed, manipulated, and explored. The AR application helps students learn about circuits through direct interaction with the circuit components without having to rely on expensive, time-consuming and dangerous experiments and equipment. The authors rely on the assumption that the use of interactive 3D models improves student learning outcomes and evaluate student attitudes towards the adoption of AR technology in classrooms. Students from the 8th grade are divided into four experimental groups based on their academic performance. The results show the effectiveness of the AR application in improving retention and understanding of physics concepts over traditional instruction methods. The experiment is not intended as a prescription for augmentation but shows that AR tools can be an efficient alternative to the risk-prone, costly laboratory environment and that such tools can be employed to enhance learning.

Develop a New Model to Measure the Blended Learning Environments Through Students’ Cognitive Presence and Critical Thinking Skills
Authors: Alismaiel Omar
Published: June 2022

Blended learning environments are one of the significant modern technology updates that could help solve many learning issues. However, blended learning is still in its developmental stage and requires more research that seeks to find more efficient models and designs for the programs of blended learning in the context of an educational environment. Therefore, this study endeavors to address this research gap by calling into question the students’ utilization of blended learning and developing a model to measure the blended learning environments through students’ cognitive presence and critical thinking skills. To accomplish the research purpose, the study used a quantitative questionnaire for data collection. A questionnaire was distributed to 85 students who are active users of blended learning environments. The collected data was analyzed using Partial Least Squares (PLS) and Structural Equation Modeling (SEM). In light of the empirical findings, the results have shown discrepancies with statistical significance at the level of (0.01) between the median marks of the students’ sample in the pre and post-evaluation of the performance analysis card. This study found a significant relationship between students’ cognitive presence and critical thinking skills with blended learning environments.
Digitally Nudged Learning

Published: June 2022

The research focused on two elements of technology enhanced learning: the digital nudge and gamified online learning. The objective was to digitally nudge students towards a gamified online learning tool, thereby improving quiz test performance through a fun motivating language learning game. A mixed methods approach: the primary quasi-experimental methodology was regression discontinuity design, with a follow up survey. The findings show that few students actively participated in the fun gamified activities, yet none-the-less there was a significant 5% treatment effect afforded by the digitally nudged call to action. The research demonstrates the effectiveness of nudging students to complete L2 learning activity. It also somewhat shows the potential of gamification for voluntary engagement amongst first-year students at a Japanese university.

Keywords—Digital nudge, Online learning, Gamification, L2 teaching/learning strategies.

The Online Teacher-Student Interaction Level in the Context of a Scenario-Based Multi-Dimensional Interaction Teaching Environment
Authors: Chen Yinchun
Published: June 2022

For teachers of online courses, figuring out the features of teaching content, setting proper teaching scenarios, and mobilizing students’ learning enthusiasm via multi-dimensional interaction are necessary works. This paper analyzed the online teacher-student interaction level in the context of a Scenario-based Multi-Dimensional Interaction (SMDI) teaching environment. At first, this paper divided the evaluation indexes of the said interaction level into four aspects. Then, this paper built a teacher-student interaction behavior preference feature model based on the Graph Convolution Neural Network (GCNN) and a teacher-student interaction relationship model based on multi-task learning, thereby realizing the accurate description of the preference features of teacher-student interaction behavior. After that, this paper elaborated on the method for accurately constructing the teacher-student interaction relationship. At last, the effectiveness of the models was verified by the experimental results.
The Role of Personal Assistance in the Uptake of Smartphone-Based Tele-Audiology—An Extension of the Technology Acceptance Model
Authors: Ross Florian , Wohllebe Atilla , Diez Erik
Published: June 2022

The arrival of new technologies in Hearing Healthcare is evident. The ability to connect hearing aids to smartphones via Bluetooth has opened up a host of new possibilities. By using an associated app, it is possible, among other things, to make an appointment with the Hearing Care Professional remotely. This function is nothing other than a further development of the classic Tele- Audiology. However, since the user base is mostly older, the question arises about the importance of the personal assistant in the clinic in setting up and explaining the technology for successful use. For this reason, a study was conducted among 110 patients who had already received such a form of intervention. For this purpose, the existing Technology Acceptance Model was further developed to include the latent variable of personal assistance. Existing basic hypotheses from other areas of application were confirmed and an additional relevant variable was identified. It could be concluded that due to a further shift of the patient generation towards baby boomers, the need for personal assistance might decrease.
Investigation of Video Streaming over MANETS Routing Protocols
Authors: T Padmapriya , Manikanthan S.V
Published: June 2022

For industrial and academic researchers from all around the world, the Mobile Ad-hoc Network (MANET) is a specific focus. A MANET was created as a result of the fast growth of wireless gadgets. Mobile Ad hoc network is a self-organizing network with no framework. MANET’s device has the ability to travel in any direction in order to transmit and receive data with other devices or network nodes. An administrator node which is capable of controlling other nodes is absent in MANET. All nodes in MANET act as its own router and host and arrange its own network. The most important element of MANET is Routing protocol. For routing in MANET, various routing protocol is responsible. Providing a video streaming service using mobile ad-hoc networks is a hard task. The network topology is immensely unstable and its instability causes data to be lost. The performance of MANET routing protocols for video applications has been examined in this paper. There are many routing protocols, however the Optimized Link State Routing (OLSR) protocol and Ad-hoc On-Demand Distance Vector (AODV) routing protocols are explored here. In this work, a comparison of these two effective routing protocols for supporting video streaming applications is offered.

Published: June 2022

Vehicle Ad-hoc Networks (VANET) are considered among recent wireless communication technologies. Nowadays, vehicles are no more than simple means of transport, they are endowed with a source of intelligence through their interaction with the road environment due to embedded equipment on board vehicles and integrated into stations along roads and highways. The mechanisms of security and protection of messages exchanged in VANET, thus preserving the privacy of users and satisfying the various security requirements, are a prerequisite for the deployment of vehicle networks. Increasingly, several research have been proposed to improve protocols for maintaining security and preserving privacy. This paper presents a hierarchical revocable infrastructure based privacy preservation authentication protocol for vehicles that involves authentication of each vehicle and the corresponding Road Side Unit (RSU) by a Certification Authority (CA). The proposed protocol used Elliptic Curve Diffie Hellman (ECDH) algorithm for reliable key exchange and Edwards-curve Digital Signature Algorithm (EdDSA) to speed up the execution of the authentication process especially at the key management level, message signing and verification of this signature. On the other hand, the creation of sub-lists of revoked certificates based on vehicle type makes it possible to minimize the response time by looking for a certificate if it is revoked or not. Our solution was checked by the security verification tool, Automated Validation of Internet Security Protocols and Applications (AVISPA), which indicated that it is a very secure level. Performance analysis illustrates that the protocol greatly saves computation resources.
CULTIVATING STEWARDSHIP IN THE NEXT GENERATION OF DESIGNERS: EMPLOYING AN EXPERIENTIAL CASEBASED METHOD USING LIVING BUILDING PROJECTS
Authors: FAIA Caryn Brause
Published: June 2022

The urgency of addressing climate change challenges architectural educators to employ methods for cultivating stewardship in emerging designers by integrating a broad array of performance domains into the curriculum. Voices from the Field is an experiential applied professional practice course that employs cases pursuing high performance building certifications to demonstrate the interrelationship of technical, organizational, behavioral, and operational domains during the process of taking buildings from concept to realization. This study contributes to the literature on teaching with case-based pedagogical methods by employing qualitative data analysis of four sets of course deliverables produced by students who studied two Living Building Challenge (LBC) projects. The findings indicate that students gained an understanding of the integrated nature of design, and an awareness of the necessity of “Backwards Design” and “Tactical Materiality” to meet contemporary climate challenges. Additionally, students increased their understanding of the strategies, attitudes, and behaviors necessary to apply their sustainable ideals to real-world dilemmas in order to build a more just and sustainable society.
FACTORS INFLUENCING ADAPTIVE REUSE OF DECLINING SHOPPING MALLS IN THE U.S.: A MULTI-STAKEHOLDER VIEW
Authors: Yang Eunhwa , Hong Sungil , Kim Yujin
Published: June 2022

The majority of shopping malls in the U.S. have few options but to repurpose their soon-to-be empty spaces. However, developers and mall owners face a challenge to find out which solutions are best for their specific situations. This paper aims to identify decision factors for the adaptive reuse of declining malls in the U.S., revealing different perspectives of multiple stakeholders. This study proposed a conceptual framework specifically for decision-makers linked to the adaptive reuse of shopping malls. The survey asked a professional opinion on the method of mall revitalization and the importance of seven decision categories: physical, economic, functional, technological, social, legal, and political aspects. A total of 41 valid responses were analyzed. Stakeholders reported different views on seven decision categories. Investors, AEC (Architect, Engineer, and Contractor) professionals, developers, and building manager groups reported the economic category as the most important variable, whereas marketer and regulator groups responded that the legal category is the most important variable. The technology was reported as the least important variable from AEC professionals, marketers, developers, and building managers. Investors and regulators indicated the social category as the least important variable. The findings of this study are rather exploratory, not conclusive due to its limited sample size. As many more shopping malls face or will face challenges of closing, the solutions for these empty or soon-to-be empty facilities should be further studied.

Published: June 2022

There have been increasing calls to coproduce psychological initiatives and services for children and young people to improve access to mental health services and service user experience. This paper outlines the development of an innovative therapeutic group for young people affected by collective trauma and loss who were reluctant to engage with mainstream services following the Grenfell Tower fire. The June 2017 apartment building fire was one of the largest and deadliest to occur in the United Kingdom (UK) in decades, with 72 deaths. The project’s central principle was partnership and coproduction with potential users and offering a culturally appropriate service. Its aim was to meet the mental health and other needs of young people, support them through their bereavement and trauma, and to improve access to mental health services by addressing the barriers they reported. The group approach used community psychology and systemic principles, narrative therapy concepts, creative arts, and collective memorialization. Semi-structured focus groups were conducted with 14 Moroccan-origin adolescents, 13 whom identify as Muslim. A thematic analysis was conducted. Findings indicated the benefits of collective memorialization and therapeutic groups, such as improved emotional expression, recognition of shared Grenfell-related experiences, strengthened social support networks and subjugated narratives, and reduced social isolation and stigma. The evaluation findings indicated that the group’s coproduction and collaboration between statutory services, potential/service users, and community organizations improved community engagement, access to mental health services, and service provision for children and young people from Moroccan and Muslim backgrounds. Note: Any views expressed in this service evaluation are of the authors and do not necessarily reflect the views of their employers.
Franz Ehrle und die Gesellschaft Jesu
Authors: Schatz Klaus
Published: June 2022

Als Jesuit hatte Ehrle seine Eigenheiten, vor allem die eines typischen Wissenschaftlers. Bei den Oberen war seine wissenschaftliche Arbeit geschätzt, vor allem weil er historische Kompetenz mit scholastischer Bildung verband. Bei mehreren Anlässen hat er als Berater der Ordensgeneräle Einfluß ausgeübt. Nachdem die Generalkongregation von 1892 die Beschäftigung mit der Geschichte des eigenen Ordens angeregt hatte, ist durch seinen Einfluß daraus ein wissenschaftliches Großprojekt entstanden. Mit seiner Beratung wurde 1893 das Archiv des Ordens von Rom in das niederländische Exaten überführt. Als 1921 die Errichtung einer Theologischen Fakultät in Frankfurt zunächst von der Römischen Studienkongregation abgelehnt wurde, hat er den Weg gezeigt, wie man dennoch das Ziel erreichen konnte, und so zur Gründung der Hochschule Sankt Georgen beigetragen.
As a Jesuit, Ehrle displayed some individual features which were those of a typical scholar. His superiors all the more appreciated his scientific contribution since he combined a scholastic training with historical expertise. In several occasions, his advices had a great influence on the General of the Order. When in 1892 the General Congregation decided to take an interest into the history of the Order, it was Ehrle who inspired the large-scale scientific project which resulted from this. It was according to his recommendations that the general archives of the Order were transfered in 1893 from Rome to Exaten in the Netherlands. Finally, in 1921, after the erection of a new faculty of theology in Frankfurt had been rejected by the Congregation of Studies in Rome, it was once again Ehrle who found out the way to realize nevertheless this goal by supporting the creation of the « High School » (Hochschule) of Sankt Georgen.
Une entreprise singulière

Published: June 2022

Heinrich Denifle et Franz Ehrle, contemporains et amis, ont lancé en 1885 la série de l’Archiv für Literatur- und Kirchengeschichte des Mittelalters, dont 7 volumes, de plus de 600 pages chacun, publiés à Berlin puis à Fribourg en Brisgau, ont paru entre 1885 et 1900. Denifle et Ehrle étaient en fait les seuls contributeurs de ces volumes qui leur permettaient de publier rapidement et sans contrainte les résultats de leurs travaux en cours. Ils n’ont cependant écrit aucun article en commun. Le volume 7 (1900) est l’œuvre du seul Ehrle. Les deux auteurs ont fait dans cette série une grande place à l’édition de manuscrits inédits, souvent tirés de la Bibliothèque ou des Archives du Vatican. On retrouve dans leurs contributions le témoignage de leurs intérêts scientifiques majeurs. Les articles de Denifle sont cependant dans l’ensemble plus courts et portent sur des sujets plus variés. Ceux de Ehrle, longs et très documentés, sont au contraire fortement centrés autour de quatre thèmes essentiels: l’histoire de la scolastique, l’histoire de la Bibliothèque pontificale, l’histoire de l’ordre franciscain et de ses courants dissidents (Spirituels et Fraticelles), l’histoire du dernier pape d’Avignon Pedro de Luna/Benoît XIII et de la fin du Grand Schisme.
Heinrich Denifle and Franz Ehrle, contemporaries and friends, founded the review Archiv für Literatur- und Kirchengeschichte des Mittelalters in 1885. Seven great volumes were published, each with more than 600 pages between 1885 and 1900, first at Berlin, later on in Freiburg im Breisgau. Because Denifle and Ehrle were the sole authors of these volumes of the review, they were able to publish their findings quickly and without limitation. However, they did not publish a common contribution. The seventh volume published in 1900 is, in fact, exclusively the work of Ehrle. The two scholars dedicated much of review to the publication of previously unpublished texts, often from the Vatican Library and the Vatican Archives. The contributions reflect their particular scientific interests. Denifle’s articles are shorter in extent and deal with a greater variety of themes. The contributions of Ehrle, often longer and closely related to sources, refer to the following main themes: the history of scholasticism, the history of the pontifical library, the history of the Franciscan order and its dissident movements (Spirituals and Fraticelli), the history of the Avignon Pope Benedict XIII (Pedro de Luna), and the end of the Great Western Schism.
Franz Ehrle et la philosophie scolastique
Authors: Mandrella Isabelle
Published: June 2022

Franz Ehrle compte parmi les grands pionniers de l’histoire de la philosophie médiévale. Il suit le concept d’une philosophie aristotelico-chrétienne perfectionnée par Thomas d’Aquin, telle qu’elle a été présentée dans l’Encyclique Aeterni Patris. Mais cela ne l’empêcha pas de développer ses propres idées concernant l’importance de l’étude des manuscrits médiévaux afin d’obtenir une vue d’ensemble de la philosophie scolastique. Ehrle fit donc remarquer que la philosophie scolastique n’est pas uniformément aristotélicienne, mais repose plutôt sur plusieurs traditions dont l’augustinisme est la plus puissante. Lui-même a cependant méconnu l’intérêt de la scolastique tardive du XIVe siècle.
Franz Ehrle counts among the great pioneers of the history of medieval philosophy. He follows the concept of an Aristotelian and christian philosophy – two characteristics that Thomas Aquinas brought to perfection – as it is shown in the encyclical Aeterni Patris. But at the same time he develops his own ideas about the fundamental role of the study of manuscripts in order to deepen the knowledge of scholastic philosophy. Thus he shows that medieval philosophy is not solely aristotelian but rather based on many traditions, so for example on augustinism which plays a significant role. He nevertheless underestimated the interest of the late scholastic of the XIVth century.
IM Banne der „franziskanischen Frage“
Authors: Heimann Heinz-Dieter
Published: June 2022

Eingebettet in den Wandel der römischen Kirche und die Ansprüche der Geschichtswissenschaft in der „Krise der Moderne“ meint die „franziskanische Frage“ seit dem 19. Jahrhundert den Nationen und Konfessionen übergreifenden Diskurs über die quellenangemessene Deutung des Franziskusbildes. Im späten 19. Jahrhundert führte dies zu einem Aufschwung in der quellenkritischen Franziskusforschung unter Historikern und Ordensleuten. Der Beitrag analysiert dazu erstmals die Arbeiten Franz Ehrles zur franziskanischen Geschichte, die zwischen 1878 und 1892 in der „Zeitschrift für Theologie“ und im „Archiv für Literatur- und Kirchengeschichte des Mittelalters“ erschienen. Ehrle leitete die Quellenanalyse philosophischer Texte, die ihn zur Auseinandersetzung mit der Deutung des Franziskusbildes des evangelischen Kirchenhistorikers Karl Müller (1885) führten. Im Bann der „franziskanischen Frage“ und früher als Walter Goetz (1904) trug er zur Verwissenschaftlichung der Ordensgeschichtsschreibung bei.
The phrase ‘the Franciscan Question’ refers to an attempt from the nineteenth century onwards to discover the ‘real’ of St Francis of Assisi by using historical analysis to distinguish the Francis of history from the image of him revered by various nations and confessions. This appeal to the sources and acknowledgement of historical sciences marked a shift in the attitude of the Roman Church and reveals something of the « crisis of the modern age ». In the latter part of the nineteenth century, this led to an upsurge in research on Francis based on critical analysis of the sources, among the historians and the members of the religious orders. The present contribution analyses for the first time the works of Franz Ehrle on the Franciscan history being published from 1878 to 1892 in the Zeitschrift für Theologie and in the Archiv für Literatur- und Kirchengeschichte des Mittelalters. Ehrle was moved by the analysis of the sources of philosophical texts which drove him to address the interpretation of the picture of Saint Francis by the historian of the Church, Karl Müller (1885), a protestant. His fascination for the “Franciscan question” led him to make a considerable contribution to the scientific approach to the historiography of the order, which predated the work of Walter Goez (1904).
Franz Ehrle e la storia delle università italiane
Authors: Frova Carla
Published: June 2022

Nella produzione scientifica di Franz Ehrle, l’edizione degli statuti della facoltà di teologia di Bologna è l’unico contributo specifico alla storia delle università medievali, tema che vide impegnato ben più ampiamente il suo amico e compagno di lavoro Heinrich Denifle. Nel preparare l’edizione, progettata fin dal 1914, ma pubblicata solo nel 1932, il dotto gesuita si giovò di una rete di scambi intellettuali che ben rappresenta il profilo della cultura storiografica italiana dell’epoca: ebbe infatti come punti di riferimento da un lato l’ambiente nobilmente provinciale degli storici bolognesi cultori delle memorie dell’Alma Mater studiorum, dall’altro quello internazionale degli studiosi che a Roma facevano capo alla Biblioteca e all’Archivio Vaticani, e agli Istituti storici stranieri. Il materiale edito da Ehrle comprende non solo gli statuti e i documenti pontifici per la facoltà bolognese, ma anche l’elenco dei teologi che ottennero il magistero e furono incorporati nel Collegio dal 1360 al 1500. Una documentazione di interesse principalmente storico-istituzionale, che Ehrle, storico della scolastica, affronta tuttavia spinto anzitutto dal desiderio di ricostruire il contesto nel quale si elaborò e si trasmise il pensiero teologico nel Trecento e nel Quattrocento. Da questo punto di vista la sua impresa ha avuto, con poche eccezioni, un’eco limitata presso gli studiosi italiani, che pure da più di ottant’anni continuano a ricorrere alla sua edizione per leggere il testo degli statuti e conoscere i nomi dei teologi bolognesi del tardo medioevo.
The only direct contribution of Franz Ehrle to his friend Heinrich Denifle’s history of the medieval universities was his edition of the statutes of the theology faculty of Bologna, founded in the 14th century. The Jesuit published this edition in 1932, as a result of exchanges with Bolognese university experts and Austrian librarians with knowledge of the manuscript conserved in the library of the University of Vienna. He edited not only the most ancient statutes of the theological faculty, but published also, in their entirety, the sources which refer to the foundation and its continued history to the year 1500. Ehrle’s interest in the faculty’s history was driven by his desire to understand medieval conditions and methods of teaching theology rather than the mere history of institutions. Scholasticism was his main interest. Ehrle’s work was well received and much used. It failed, however, to this day to arouse any real interest in the history of theological teaching, a subject too often seen by Italian historians as marginal, having been monopolised in both medieval and modern times by the religious orders.
