Authors: Laakkonen Mika-Petri , Kivivirta Ville , Calò Antonio , Pongrácz Eva
Published: November 2024

This article presents the evolution of a smart grid in an artic city, and we analyze its development using the Smart Grid Reference Architecture (SGAM) and from historical, technological, and social points of view in an Arctic context. We illustrate the emergence of smart grid application and its relation to energy consumption habits and sustainability. The study includes observations from empirical research conducted using a mixed methods approach. This included two months of organizational ethnographies consisting of interviews with specialists at an electricity utility, shadowing the workers, participant observation in the control center, and a questionnaire survey among local residents. Three stages of transformation in the electricity network were observed: 1) the conversion from analog to digital in network operations, with residents as passive receivers of electricity; 2) introducing digital communications and a digital local area network that allowed residents to report consumption; 3) the electrical network as an evolving smart grid with a digital platform enabling two-ways communication among network actors. People became more active when smart grid applications were introduced in the electricity network and middle-aged men can now better manage their energy consumption, even though their motivation is financial, rather than environmental. At the same time, unplugging from the smart grid becomes increasingly difficult.

Background: Infections attributable to respiratory syncytial virus (RSV) are a major cause of hospitalization among young children worldwide. Despite substantial clinical and economic burden, real-world data associated with RSV infections in the United Arab Emirates (UAE) are limited.

Objectives: This study aimed to assess among children (<18 years) diagnosed with RSV the epidemiology, seasonality, comorbidities, treatment patterns, length of hospital stay, healthcare resource utilization (HCRU), and costs associated with pediatric infection in Dubai, UAE.

Methods: This 10-year retrospective cohort study (Jan. 1, 2014–Sept. 30, 2023) utilized Dubai Real-World Database, a private insurance claims database. Patients aged <18 years with a first-episode diagnosis claim (primary or secondary, or a hospital admission) for RSV any time during the index period (Jan. 1, 2014–June 30, 2023) were included. Outcomes were analyzed during a 3-month follow-up. Patients were stratified into 3 cohorts: Cohort 1 (<2 years), Cohort 2 (2 to <6 years), and Cohort 3 (6 to <18 years).

Results: Of 28 011 patients identified, 25 729 were aged <18 years with RSV infection. An increasing trend in reported cases was observed from 2014 to 2022, with an average annual increase of 55%. Half of study patients (49.3%) belonged to Cohort 1, with a mean age of 0.6 years, while less than 2% had known risk factors and 22% of the patients in cohort 1 were hospitalized. In Cohort 1, 32.0% had upper respiratory tract infections, 39.4% had lower respiratory tract infections, and 44.4% of patients had an “other respiratory disease.” The average length of hospitalization was about 4 days across all cohorts. The total hospitalization cost was highest in patients <2 years, amounting to US $9 798 174 (median, US $2241.30).

Conclusion: Among the RSV patients, 49.3% were <2 years of age and few had recognized risk factors. Among patients <2 years, 22% were hospitalized, with an average hospital stay of 4 days; the cost of hospitalization totaled US $9 798 174. These findings can inform healthcare stakeholders about future policy measures and the need for effective preventive strategies.

Objective: There is a surge in the availability of alcoholic products accompanied by a high rate of consumption despite increasing neurological problems. Aim of this study is to determine whether regular intake of brewed beer and red wine affects the microanatomy of the cerebral cortex, hippocampus and brain weight.
Materials and Methods: 20 male albino Wistar rats were assigned to four groups of five animals each. Group A, the control was given distilled water; Group B was administered 5 mL/kg body weight of beer; Group C received 5 ml/kg of red wine; and Group D was dosed with 5 ml/kg of beer and followed with 5 ml/kg of red wine. Daily treatments by gavage lasted 15 days, and animal subjects were euthanized via cervical dislocation on day 16. Individual brains were collected and weighed using an electronic scale (SF-400) and afterwards dissected to obtain tissue samples from the cerebral cortex and hippocampus, immediately fixed in 10% formalin for micro-anatomic studies. The paraffin embedding method was used for histological preparation while sections were cut at 5 µm and stained with hematoxylin and eosin. Brain weight was analyzed using the Statistical Product and Service Solutions (SPSS) software via one-way analysis of variance.
Results: Histopathological changes including intracerebral haemorrhage and loss of pyramidal neurons observed in group B (beer) samples were not visible in Group D (beer plus red wine), while no microstructural changes occurred in group C (red wine) sections when compared with the control. The output of statistical analysis showed a non-significant reduction in brain weight of group B, whereas a significant increase was noticed in group C while group D showed a non-significant increase.
Conclusion: These findings indicate that red wine counteracts beer-induced changes in brain morphology, hypothesising the neuroprotective effect of the wine.

Published: November 2024

Na prática clínica, a Medula Óssea (MO) é frequentemente usada em Transplantes de Células-Tronco Hematopoéticas (TCTH), com seu uso em humanos iniciado em 1957. A escassez de doadores e limitações do método ressaltam a necessidade de alternativas terapêuticas, como o sangue do cordão umbilical e placentário (SCUP), que tem se mostrado uma fonte valiosa de células progenitoras hematológicas. A leucemia é caracterizada pelo acúmulo de células malignas na medula óssea, sendo a Leucemia Linfoblástica Aguda (LLA) mais comum em crianças. O tratamento inicial é a quimioterapia, podendo incluir o TCTH em casos de risco elevado. O TCTH, especialmente com SCUP, apresenta vantagens como menor risco de doença do enxerto versus hospedeiro. Este estudo objetiva realizar uma revisão bibliográfica sobre o uso de SCUP em pacientes com LLA. Foi realizada uma revisão da literatura utilizando bases de dados como PubMed, SciELO e Google Acadêmico. A revisão implica que as SCUP se destacam por não exigirem total compatibilidade dos Antígenos Leucocitários Humanos (HLA), o que facilita sua utilização em transplantes. Elas são jovens, não expostas a agentes patogênicos, resultando em menor risco de complicações e rejeições pós-transplante. No entanto, a quantidade de células coletadas pode ser limitada, restringindo doações a indivíduos com peso inferior a 50 kg. Estudos mostram que o SCUP pode levar a melhores taxas de sobrevida em comparação à medula óssea, especialmente em pacientes sem doadores compatíveis. Apesar dos riscos associados, o SCUP é uma alternativa viável e acessível. Pesquisas continuam a investigar a eficácia do SCUP em relação a outros tipos de transplante, com resultados promissores, especialmente em crianças e jovens adultos. É importante que a escolha do tratamento seja individualizada, considerando as características de cada paciente e discutida com a equipe médica.

Introdução: O Traumatismo Cranioencefálico (TCE) diz respeito a qualquer dano que afete o crânio e/ou o cérebro. No Brasil, essa condição se destaca como uma significativa causa de adoecimento, gerando altos gastos com saúde e longos períodos de internação hospitalar. O tema de traumas intracranianos em crianças e adolescentes ainda é pouco abordado. Este trabalho busca investigar a epidemiologia do TCE em jovens brasileiros entre os anos de 2012 e 2022. Para isso, foi realizado um estudo descritivo e analítico, que utilizou dados do DATASUS sobre traumas intracranianos em indivíduos de 0 a 19 anos nesse período. Na análise, foram contabilizadas 247.116 internações, com 8.936 óbitos, resultando em uma taxa de mortalidade de 3,61%. O custo médio da internação foi de R$266,30 por dia, com um tempo médio de hospitalização de 4,2 dias. O perfil epidemiológico dos pacientes que sofreram traumáticas cranioencefálicas revela que a maioria são homens pardos, com idades entre 15 e 19 anos, principalmente provenientes da região sudeste do país. A discussão ressalta que a morbidade e a mortalidade são mais pronunciadas entre os jovens dessa faixa etária, devido aos elevados custos relacionados a intervenções cirúrgicas e clínicas, necessárias para o tratamento de infecções ou a drenagem de hematomas intracerebrais. O custo do tratamento após a alta hospitalar é um tópico pouco explorado, embora esteja ligado ao cuidado de sequelas, à prevenção de novas lesões e ao acompanhamento multidisciplinar especializado. Em conclusão, o TCE em jovens é uma questão de grande relevância social, gerando impactos negativos e um número significativo de mortes. Assim, é imprescindível a criação de estratégias preventivas que visem a diminuição desses acidentes traumáticos.
O princípio de não contradição
Authors: Lima João Paulo , Pereira Claudinei Reis
Published: November 2024

It is common to have a diminutive notion of the principle of non-contradiction, since normally it is only posited as a logical principle, but it is above all an ontological principle, the very ulterior manifestation of being. Indeed, it will help us answer the central question: how does being manifest itself in the multiplicity of entities? In this way, it is mostly necessary to present the manifestation of being through its ontological principle in the ontological, ontic and gnosiological planes of the real. From this, to clarify the impossibility of demonstrating the principle of non-contradiction and how this leads to the principle of the excluded middle; to explain the principle of identity as the synthesis and affirmation of thought, establishing the coincidence between being and thinking; and also to relate the principle of non-contradiction with essential and accidental semantic predication. For this, a qualitative approach is used with a bibliographic character of descriptive nature, making use of the doctrinal analysis. As a result, the presence of the same principle in beings of all natures is perceptible. Concluding that being, through the principle of non-contradiction, manifests itself in the multiplicity of entities.
Gələcək müəllimlərin peşə hazırlığına verilən psixoloji tələblər

Xülasə Məqalədə müəllim hazırlığının psixo-pedaqoji məsələləri və bu mövzuda aparılan tədqiqatlar diqqətə alınır. Müəllim hazırlığı prosesində yaranan çətinliklər bir sıra amillərlə bağlıdır. Bu amillər arasında müxtəlif ölkələrin təhsil sistemləri arasındakı fərqlər, tədris prinsipləri və metodlarının fərqli şəkildə tətbiqi, eləcə də müəllim hazırlığına dair müxtəlif konseptual modellərin mövcudluğu göstərilə bilər. Müxtəlif təhsil sistemlərinə uyğun olaraq müəllim hazırlığı modellərinin mexaniki şəkildə tətbiq olunmaması səbəbindən bu sahədə dərindən araşdırma aparılması zəruridir. Məqalədə tədqiqatlar məkan və işlənmə səviyyəsinə görə iki qrupda - yerli və xarici tədqiqatlar kimi qrup­laşdırılır. Bu tədqiqatlar göstərir ki, müəllim hazırlığına yanaşmalar əsasən müəllim şəxsiyyətinə qoyulan tələblər, pedaqoji fəaliyyətin psixoloji aspektləri və müəllim hazırlığının ümumi məsələləri əsasında həll edilir. Belə bir qənaətə gəlinir ki, daimi və konstruktiv özünü­qiymət­lən­dirmə meyli müə­llimin yetkin pedaqoji fəaliyy­ətini səciyyələndirir. O, müəllimin əməyinin mahiyyətini təyin edir. Əgər insan özü-özünü başa düşə bilmirsə, o, digər insanın motivlərini və hisslərini başa düşməyə qadir deyildir. Buna görə də pedaqoji özünütəhlil, özünüadekvat qiymətləndirmə müəllim hazırlığında və pedaqoji fəaliyyətində daha vacibdir.
Multikultural dəyərlərin inkişafında medianın rolu
Authors:   AEM ( Azerbaijan Science Center ), Allahverdiyeva Fidan
Published: November 2024

Xülasə Multikulturalizm müxtəlif etnik, dini və mədəni qrupların bir arada yaşadığı və qarşılıqlı anlaş­ma və hörmətin vacib olduğu cəmiyyətlərdə geniş yayılmış bir anlayışdır. Medianın bu çərçivədə rolu isə cəmiyyətlər arasında əlaqələrin möhkəmləndirilməsi və müxtəlif mədəniyyətlər arasındakı dialoqun inkişaf etdirilməsi kimi mühüm aspektləri əhatə edir. Məqalədə ilk növbədə medianın əsas funksiyalarından biri kimi məlumatlandırma və maarif­ləndirmə funksiyası vurğulanır. Media cəmiyyətə müxtəlif mədəniyyətlər, onların tarixi, ənənələri, adətləri və dəyərləri barədə geniş məlumat verir. Bu isə insanların müxtəlif mədəniyyətlərə daha dərin və obyektiv yanaşmalarına, anlaşılmazlıq və stereotiplərin aradan qaldırılmasına şərait yaradır. Medianın doğru və balanslı məlumat verməsi, fərqli xalqların və qrupların mədəni irslərinin qorunmasına və təbliğinə töhfə verə bilər. İkinci əsas məqam medianın sosial məsuliyyətidir. Multikultural cəmiyyətlərdə medianın rolu təkcə məlumat ötürməklə məhdudlaşmır, eyni zamanda medianın yaratdığı məzmunun müxtəlif qruplar arasında qarşılıqlı anlaşmaya necə təsir etdiyi də əhəmiyyət kəsb edir. Bu baxımdan, media düzgün və etik qaydalar çərçivəsində fəaliyyət göstərməli, ayrı-seçkiliyin, nifrətin və ya təfriqənin yayılmasının qarşısını almalıdır. Daha sonra, məqalədə medianın müsbət tərəfləri ilə yanaşı, mənfi təsirləri də qeyd olunur. Bəzi hallarda media orqanları multikultural cəmiyyətlərdə mövcud olan mədəni və dini fərqliliklərə diqqətsiz yanaşaraq, qütbləşmə və qarşıdurmaların yaranmasına səbəb ola bilər. Xüsusilə, sensasiya və ya yanlış məlumat yayılması, cəmiyyətdəki incə balansı poza bilər. Buna görə də media qurumlarının peşəkar və obyektiv informasiya təqdim etmələri, etik prinsipləri rəhbər tutmaları vacibdir.

Published: November 2024

Abstract This paper explores the typologies of risks in the banking sector and examines the strategies employed to mitigate them, with a focus on Azerbaijani banks. The study identifies key risk categories, including credit risk, market risk, liquidity risk, and operational risk, each of which plays a critical role in the financial health and profitability of banks. The research highlights that credit risk, driven by loan defaults, remains the most significant concern for Azerbaijani banks, while market risks, particularly from currency fluctuations, also pose major challenges. Effective risk mitigation strategies, including collateralization and diversified lending practices, are essential to maintaining stability in this emerging market. Additionally, the study emphasizes the importance of integrating modern risk management technologies and adhering to international regulatory standards. Azerbaijani banks that adopt advanced monitoring systems and proactive risk management frameworks demonstrate improved financial performance and resilience in the face of economic volatility. The findings underscore that well-implemented risk management practices are crucial for enhancing profitability and ensuring long-term sustainability in the banking sector.

Published: November 2024

Özet Bu çalışmada amacımız göze ait biyometrik özellikler ve ekstraoküler kas konfigürasyonunun horizontal şaşılık cerrahisi başarısındaki etkisini değerlendirmektir. Kliniğimizin Şaşılık Birimi’nde horizontal şaşılık nedeni ile cerrahi tedavi uygulanan 28 hasta çalışma kapsamına alındı. Şaşılık cerrahisi yapılan hastaların ameliyat öncesi ve ameliyat sonrası üçüncü ayda yapılan oftalmolojik, ortoptik ve biyometrik muayene bulguları kaydedildi. Rutin muayeneye ek olarak aksiyel uzunluk ve keratometri parametreleri değerlendirildi. Cerrahi sırasında hastaların yaş ortalaması 7,79±7,43 (1,0-38,0) yıldı. Hastalar esotropya, ekzotropya ve infantil esotropya olarak üç gruba ayrıldı. Ameliyat sonrası esotropya (ET) için yakın ve uzak kaymanın 10 prizm diyoptri (pd) ET ve altında olması; ekzotropya (XT) için yakın ve uzak kaymanın 10 pd ET ve XT altında olması - başarılı; yakın veya uzak kaymanın birinin 10 pd ve altında olması - kısmi başarılı; 10 pd üzerinde olması başarısızlık belirlendi. Cerrahi başarı incelendiğinde %46,4 hastanın cerrahisi başarılı, 39,2% hastada kısmi başarılı, %14,4 başarısızdı. Kırma kusuru tipi, kayma tipi, füzyon ve stereopsis varlığı ile cerrahi başarı arasında ilişki saptanmadı (p=0,403; p = 0,183; p=0,316; p=0,259). İç rektus insersiyosunun (‘a’, ‘b’, ‘c’) limbusa olan mesafesi ve (‘d’) genişliği, arttıkça cerrahi başarı oranının arttığı saptanmıştır (p=0,058; p=0,026; p=0,019; p=0,058). Sonuç olarak, aksiyel uzunluğun ve ekstraoküler kas anatomisinin, horizontal şaşılıklarda cerrahi başarıyı etkileyen faktörler arasında bulunduğu gösterilmiştir.

Adətən titandan ibarət olan diş implantı diş kökü funksiyasını yerinə yetirmək üçün cərrahi yolla mandibula daxil edilir. Həqiqi dişin görünüşünü və hissini təkrarlamaq üçün implanta möhkəm bir şəkildə sümüyə daxil edildikdən sonra tac yapışdırılır. Bir çox tac qüsurları, o cümlədən aşınma, travma və ya çürümə nəticəsində yaranan qüsurlar bərpa proseduru zamanı düzəldilə bilər. Davamlılıq, sabitlik və qonşu dişlərin və sümük qurulu­şunun qorunması diş implantlarının yalnız bir neçə faydasıdır. İmplantlar körpülər kimi dəstək üçün yaxınlıqdakı dişlərdən asılı olmadığı üçün əlavə zədələnmə şansı daha azdır. Prosedur baxımından terapiya adətən mərhələlərlə aparılır. İmplantasiyadan sonrakı sağalma mərhələsində implant sümüklə birləşir (osseointeqrasiya). İmplant sabitləndikdən sonra onun üstünə xüsusi hazırlanmış tac qoyulur.

Lipid peroxidation is implicated in the development of hypertension and coronary artery disease, and its deleterious impact is exacerbated by estrogen (ETD) depletion in post-menopausal women. We hypothesize that treatment with ETD and antihyperlipidemic drugs, either alone or in combination, can alleviate the development of cardiovascular disease. In this study, female Wistar rats were divided into 10 groups (n = 6): Group 1 (control) underwent a Sham operation and was fed standard rat chow, whereas the other nine groups were ovariectomized (OVX) and received a diet containing either thermoxidized palm oil (TPO) or thermoxidized soya oil (TSO) for 12 weeks. ETD at 0.2 mg/kg/day, atorvastatin (ATV) at 10 mg/kg/day, and a combination of ezetimibe (EZE) and ATV (EZE at 3 mg/kg/day + ATV at 10 mg/kg/day) were administered for 12 weeks in both TSO and TPO diet groups. Blood pressure and electrocardiogram (ECG) parameters were assessed, along with serum lipid profile, atherogenic indices, and markers of oxidative stress. Both TPO and TSO diets significantly altered blood pressure and ECG parameters in OVX rats. Treatment with ATV, EZE+ATV, and ETD significantly reduced blood pressure parameters compared to the OVX+TPO group. Antihyperlipidemic drugs significantly decreased heart rate, QT interval, QRS duration, and QT corrected (QTc), whereas ETD similarly shortened the QRS and QTc duration. ATV and ETD also reduced total cholesterol, triglycerides, and very low-density lipoprotein levels, while boosting high-density lipoprotein concentrations compared to untreated OVX+TSO rats. This study demonstrates that thermoxidized oil has a deleterious effect on OVX rats by altering blood pressure, ECG parameters, and atherogenic indices. Treatment with antihyperlipidemic drugs and ETD normalized blood pressure and ECG parameters, reversed hyperlipidemia, and restored antioxidant system balance.

Glyphosate (GLYPi) is an organophosphorus herbicide that behaves as an anionic substance in the aqueous phase. Even though it is stated as safe and non-toxic, the widespread use of GLYPi has raised environmental issues that need attention. This work used the positively charged metal-organic framework (MOF) of ZIF-8 to remove GLYPi via adsorption. Fe3O4 particles were hybridized with ZIF-8 to obtain Fe3O4@ZIF-8 via an in-situ deposition strategy to enhance the adsorption capacity toward GLYPi. The composite material (Fe3O4@ZIF-8) was characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction, revealing rhombic dodecahedron-shaped particles and oxygen-rich functional groups. The adsorption results show that there is a synergistic effect of adding Fe3O4 to ZIF-8 in increasing the rate and capacity of adsorption on GLYPi, that is 0.0012 g/mg·min (Pseudo-second-order) and 73.57 mg/g (Langmuir), respectively, on pH 7 and 50 °C. GLYPi adsorption by Fe3O4@ZIF-8 was not influenced by coexisting anions (e.g., Cl-, NO3-, SO42-, and HCO3-). The reusability study showed that the adsorption efficiency of GLYPi by Fe3O4@ZIF-8 decreased significantly after the first cycle, which should be considered a future challenge for further studies. The adsorption mechanisms of GLYPi by Fe3O4@ZIF-8 involve electrostatic interaction and pore-filling. The results indicate that Fe3O4@ZIF-8 is a promising candidate for removing organophosphate compounds, which could be an excellent strategy for environmental protection.
Pressure-Driven Batch Distillation Optimal Control for Acetone-Methanol Separation
Authors: Stojkovic Marija
Published: November 2024

Over the last fifteen years, immense progress has been made in the research of pressure-swing batch distillation. The challenge lies in the fact that certain pressure-sensitive azeotropic mixtures cannot be separated in a regular open batch mode with an acceptable outcome. Throughout most of this text, findings contradict previously established facts. The separation of acetone-methanol by pressure-swing batch distillation in a mixed double system, consisting of a regular and inverted column, is the process under investigation. In this work, a comprehensive global solution to the optimal control problem is derived in the form of a sequential synthesis of controlled trajectories. A thorough analysis of the control variables, with and without parametric sensitivity of manipulated variables, on the optimal control pattern with variable reflux is presented. Most authors did not achieve significant results by simultaneously optimizing reflux and liquid division ratios or by using a "variable pressure gap." This study challenges previous findings, emphasizing the importance of simultaneous optimization of all three factors mentioned. During this study, the optimal reflux strategy through cyclic operation was extended to optimize energy expenditure over a fixed time horizon. Moreover, the proposed scheme offers a high level of operational flexibility, allowing units to be operated independently or as a system. Additionally, the facility of connecting additional devices is highlighted by the significant difference in output temperatures and the potential for using evaporated fluids consecutively. Lastly, the research provides a solid basis for future investigations into internal and external heat integration, potentially leading to conclusions about expanding the network using well-known heat cycles.

The application of garlic peel was investigated as a low-cost biosorbent for Cd2+, Ni2+, Zn2+, and Pb2+ from aqueous solutions in a continuous system. Experiments were carried out in a fixed bed column, and the influence of different flow rates (from 2.0 to 3.3 ml min-1) on the breakthrough was studied. Column data obtained at different conditions were described using the Bohart-Adams, Thomas, and Yan models. The maximum amount of absorption was obtained for a lead ion with the amount of 490.68 mg g-1. The column removed 472.78 and 135.17 mg g-1 of cadmium and nickel ions, respectively, and the minimum value was obtained for zinc ions (55.08 mg g-1). The garlic peel was regenerated and reused two to four times in successive biosorption-desorption cycles. Differential pulse voltammetry (DPV) was used to measure kinetic models for the biosorption of lead and cadmium ions on garlic peels. Using DPV for lead and cadmium ions, the amount of adsorbed material was obtained at 2.58 and 2.23 mg g-1 using the pseudo 1st order equation and this value was obtained at 8.26 and 4.70 mg g-1 using the pseudo 2nd order equation for lead and cadmium ions, respectively. The results show that garlic peel absorbs lead and cadmium ions more than zinc and nickel ions. Because it is made up of several sulfur compounds, sulfur as a soft atom has a stronger interaction with lead and cadmium than other ions.
A Deformed Child and the ‘Fault’ of his Mother: the Monster of Bourges in Gregory of Tours*
Authors: Cassia Margherita
Published: November 2024

Abstract As Gregory of Tours reports (De virtutibus sancti Martini 2.24), in Bourges a child, ‘sinfully’ conceived on a Sunday night and born fearfully deformed, was nevertheless cared for by his mother, who refused to kill it, resisted the derision of
neighbors and finally entrusted it to a group of beggars. The story of this monstrum – healed by two miracula performed by Saint Martin – allows us to formulate some reflections on socio-cultural (the connection between morbum and peccatum), economic
(poverty, inheritance calculations, family planning), and juridical aspects (the relationship between imperial laws and ecclesiastical legislation) connected with abandonment and/or infanticide which, in always spell out 6th-century Gaul, could be the sad destiny of those with severe psychophysical
handicaps.
Ulrich von Zatzikhoven, Lanzelet: Stabreimende Wortpaare im mittelhochdeutschen Kontext
Authors: Jeep John M.
Published: November 2024

Abstract Zum ersten Mal werden hier alle stabreimenden Wortpaare in Ulrichs von Zatzikhoven Lanzelet verzeichnet und nach bewährter Methode1 im Kontext der alt- und mittelhochdeutschen rhetorischen Praxis dargestellt. Eine vergleichbare Studie2
zum Wigalois Wirnts von Grafenburg ist jüngst erschienen, so dass diese einander ähnlichen Werke im Lichte ihrer poetischen Praxis miteinander verglichen werden können. Auf das Verzeichnis der Wortpaare chronologisch nach ihrem Erscheinen im Text geordnet folgt eine Einzelanalyse
unter Einbeziehung bisheriger Forschungsergebnisse. Die Geschichte der stabreimenden Wortpaare im Frühdeutschen erreicht hiermit – bei aller Vorsicht bezüglich der Datierung – das zweite Jahrzehnt des 13. Jahrhunderts mit über 1.500 Belegen. Somit ist die Bedeutung
dieses rhetorischen Elements auch in der Anzahl der nachgewiesenen Textstellen erkennbar geworden.
“Do Me Justice and Burn Me” – A Repentant Jewish Convert in Late Medieval Vienna*
Authors: Brugger Eveline
Published: November 2024

Abstract A short note in an early fifteenth-century manuscript, most likely written at the University of Vienna, describes the hitherto unknown case of a Jewish proselyte who sought active repentance for his apostasy from Judaism by demanding from the Christian authorities
that he be burned in retribution for his transgression, and who was consequently executed by fire in 1410. The incident is without parallel in the medieval history of Jews in the Duchy of Austria; prior to the catastrophic persecution of 1420–1421, known as the Vienna Gesera, neither
the Habsburg dukes nor church officials showed an active interest in the conversion and baptism of Jews despite an ongoing theological debate on the subject at the University of Vienna. This paper therefore attempts to place the case of the repentant convert in the context of the general attitudes
toward Jewish conversion among territorial rulers, ecclesiastical and municipal authorities as well as Jewish communities in late medieval Austria.

Medieval Studies are progressing today because we are increasingly embracing interdisciplinary approaches and also accepting the notion that we need to pursue, as much as that is possible, global perspectives. As far as interdisciplinarity is concerned, we can clearly observe how new
insights result when we consider the contexts of literary texts, of stained glass windows, mystical accounts, or chronicles. No sources from that time period (or from beyond) exist within a vacuum, so it proves to be truly exciting when scholars offer new understandings of the material dimensions
of medieval art, literature, music, religion, and architecture, for instance. For quite some time, the aspect of color has intrigued many different scholars (see the 2-vols. collection of articles edited by Ingrid Bennewitz and Andrea Schindler, Farbe im Mittelalter, 2011; the study
by Monika Schausten, Die Farben imaginierter Welten, 2012; the vol. ed. by Roberta Panzanelli, The Color of Life, 2008; and William Jervis Jones, Historisches Lexikon deutscher Farbbezeichnungen, 5 vols., 2013). We now have available the remarkable study by Alberto Virdis,
which offers an excellent historical overview of the relevant discourse on colors from the early twelfth to the middle of the thirteenth century.
Susan Weissman, Final Judgement and the Dead in Medieval Jewish Thought. London: The Littmann Library of Jewish Civilization, 2020, viii, 443 pp.
Authors: Bruce Scott G.
Published: November 2024

Given recent scholarly interest in pre-modern attitudes toward the return of the dead and the afterlife, it is surprising that so little work has been done on the relationship between the living and the dead in medieval Jewish thought. This book offers to fill this lacuna with a study
of the views of Ashkenazi Jews on this topic. It focuses on the so-called German Pietists (Hasidei Ashkenaz), who followed the teachings of R. Judah the Pious (1150−1217), and makes extensive use of the Sefer hasidim, a multi-author compendium of Jewish religious practices written
in Hebrew that circulated in the Rhineland in the decades around 1200. It is clear from this rich source that Pietist thinking about the dead and the afterlife differed considerably from inherited traditions of rabbinic scholarship. Following in the footsteps of Joshua Trachtenberg’s
classic study Jewish Magic and Superstition: A Study in Folk Religion (1939), Weissman argues that the Sefer hasidim bore the indelible imprint of “death-related beliefs and practices that circulated in the Germano-Christian environment of the time” (3).
La Version Z de l’Ovide moralisé, ed. Prunelle Deleville. Paris: Classiques Garnier. Textes littéraires du Moyen Âge, 2023, 2 vols., 2103 pp.
Authors: Rouillard Linda Marie
Published: November 2024

Prunelle Deleville has produced an impressive accomplishment with this first critical edition of a 72,000 verse, early fifteenth-century version of the Ovide moralisé, an example of the evolution of the fourteenth-century anonymous Ovide moralisé,
itself an adaptation of the classical work. Deleville comes to this work with much expertise: a 2022 publication with Garnier entitled Métamorphose des Métamorphoses: la réécriture de la version Z de l’Ovide moralisé, a critical analysis of the
poem. Her 2019 dissertation at the University of Geneva includes a critical edition and commentary on this fifteenth-century version. Deleville also published a 2021 article entitled “The Ovide ‘rémoralisé’: The Z Rewriting of the Ovide moralisé”
in Medium Aevum. Here she explains her qualification of the Z manuscripts not as translations of the Latin original or as transcriptions of the fourteenth-century version, but as rewritings.

The Cambridge Codex (T.-S.10K22, 1382) cannot be overstated in its importance for Old Yiddish Studies. This fragmentary text, found in the Cairo Genizah (a religious-cultural storage place for texts that can no longer be used), contains poems from biblical-Midrashic and non-religious
sources in a Germanic language in Hebrew letters, often described as an early stage of Yiddish. The whole codex was made accessible to a broader audience in a 1957 edition by Lajb Fuks accompanied by a transliteration and translation into German (Lajb Fuks, The Oldest Known Literary Documents
of Yiddish Literature [c. 1382], Leiden 1957). The best-researched text of this collection is the so-called Dukus Horant (Duke Horant), a fragmentary text closely related to the Middle High German Rother (late 12th ct.) and Kudrun (ca. 1250). Scholars disagree on the
cultural-social status of Dukus Horant as well as its language; it is at times described as Middle High German in Hebrew letters (John Howard, Manfred Caliebe), at times as proto-Yiddish/ Old or West Yiddish in its earliest form (Salomon A. Birnbaum, Jerold Frakes).

Narratologically speaking, the emergence of the poetic “I” in late medieval and early modern European literature constitutes a major benchmark of a long-term paradigm shift which ultimately transcended into the Baroque novel written entirely from the first-person perspective,
such as the anonymous Spanish Lazarillo de Tormes (1552) and Grimmelshausen German Simplicissimus (1668). However, already high medieval romances such as Wolfram von Eschenbach’s Parzival (ca. 1205) or allegorical narratives such as Hartmann von Aue’s Klagebüchlein
(ca. 1180) contain remarkable elements of the playful engagement with the own self. Those are, unfortunately, not even mentioned by any of the contributors to the volume under review here. We also should not forget the strong development of autobiographical poetry in the fifteenth century
(cf. A. Classen, Autobiographische Lyrik des europäischen Spätmittelalters, 1991), such as by Oswald von Wolkenstein, Christine de Pizan, Thomas Hoccleve, and Michel Beheim (none of them is considered here). However, the present project excellently edited by two German and
one American scholar, aims at the analysis of the conjunction of allegory with the first-person pronoun mostly in late medieval French, some Italian, German, and Spanish allegorizing verse narratives, often in the form of the dream allegory. As the editors emphasize, the exploration of the
poetic “I” takes place within a literary discourse, it represents an experimental process, and it reflects the very nature of fictionality (meta-fictionality), which can easily lead to the splitting of the poetic self. Whether this justifies them to call this development transgressive,
“oscillating between story and discourse” (15), might be questionable, however.

The twenty-six essay contributions to this edition are heartfelt, touching testimony to the scholarly contributions and mentorship of Professor Lawrence Earp. Numerous are the descriptions of his generosity and guidance to students and colleagues. His award-winning book Guillaume
de Machaut: A Guide to Research (1995) is considered to be the fundamental comprehensive starting pointing for any scholar of this medieval composer and poet. The topics addressed in this collection range from historical context of Machauts life to literary analysis of his poetry, to manuscripts
and illuminations of his works, to musical analysis and performance practices. Along with a few essays dedicated to general medieval music, poetry, and theater, and even to Hildegard of Bingen, this volume demonstrates the deep, wide-spread influence of Prof. Earp on a generation of students
and scholars.

Authors: Breeze Andrew
Published: November 2024

Peredur, a thirteenth-century Arthurian romance in the Mabinogion collection, here encounters the trinity of poststructuralism, postmodernism, and postcolonialism. Hence references to Mikhail Bakhtin, Michel Foucault (whose Ceci n’est pas une pipe prompts
the title), and Gayatri Chakravorty Spivak, as well as to professional Celticists at Cambridge (where the author wrote her doctorate) and Aberystwyth. Analysis is set out in six chapters: first, on the tale’s structure; second, its topography and landscape; third, historical context
(with emphasis on Constantinople and its Empress); fourth, its relationship to other texts (some now lost); fifth, implications of Welsh law; sixth, problematic characters, including the Witches of Gloucester. Thanks to such analysis, we may stop dismissing this “as a strange text that
makes no sense” (p. 7) once we perceive aspects in it that were familiar to early audiences, but not to us. There is also stress on ‘fractals,’ a geometrical expression for ‘objects that are scale-symmetric and self-similar,’ and so display identical patterns
in infinite regress, like a ‘snowflake’ (p. 24) or, better, ice crystals within a snowflake. Peredur supposedly has many ‘fractals.’ A surprising judgment, given the view of Sir Idris Foster (in a chapter cited by the author) on its plot as ‘chaotic.’

For many medievalists, it is a bit hard to remember that life in the pre-modern world was just a little more than only the Arthurian court, the crusades, the discourse on love, the Gothic cathedral, and the like. In reality, people had to eat, to get clothing, and to find shelter. Those
mundane aspects tend to be forgotten easily, but they were really the essentials, and we would do a grave disservice if we ignored them in all our well-intended studies in the field of literature, history, art history, or philosophy. No monastery could exist without a garden; all peasants
ran their own gardens; the courts had gardens, and the urban dwellers certainly also needed fresh vegetables and fruit, just as today. But a garden requires care, expertise, labor, and resources. Hence, already in antiquity and then throughout the Middle Ages, treatises were written addressing
gardening, such as the one by Pierre de Crescens, or rather Pietro de’ Crescenzi (ca. 1230/33–ca. 1320), a highly regarded Bolognese jurist, now most famous for his horticultural discussions recorded in his Liber ruralium commodorum. The present book offers a voluminous
introduction to this text and an edition of the French translation of the first eight books (the rest, four more books, will hopefully appear in a follow-up volume). Pietro based his treatise, as was to be expected, extensively on classical (Columella, Palladius) and medieval (Albertus Magnus)
sources, but he certainly drew also quite considerably from his own experiences as an estate owner.
A Companion to the Abbey of Quedlinburg in the Middle Ages, ed. Karen Blough. Brill’s Companions to European History, 29. Leiden und Boston: Brill, 2023, pp. xx, 477.
Authors: M. Jeep John
Published: November 2024

Following upon two Brill’s Companion volumes on medieval German-speaking cities, Lübeck (2019) and Vienna (2021), Blough has assembled twelve essays on the history of Quedlinburg, today a small yet once important imperial seat in what later became East Germany (GDR); its
municipal history reflects the abbey’s often radically evolved environment. While the focus throughout is Quedlinburg’s medieval legacy, the roles of her buildings and devotional objects can only be understood in the present by reflecting on the changes that they have undergone.
Much evidence has been lost, both allowing for and demanding careful speculation on what occurred as much as a millennium ago.
