Lactancia materna en mujeres sordas: revisión de la literatura
Authors: Pla-Serrano Inés , Mena-Tudela Desirée
Published: October 2024

Introducción: La lactancia materna exclusiva presenta tasas demasiado bajas en todo el mundo. Se considera que las tasas de lactancia materna en mujeres sordas son todavía más bajas. Material y métodos: Se ha llevado a cabo una revisión de la literatura con el objetivo de explorar las barreras y los apoyos que se encuentran las mujeres sordas con la lactancia materna. Los estudios fueron identificados a través de una búsqueda bibliográfica en las diferentes bases de datos: PubMed, Web of Science, Science Direct, Scopus y Proquest entre los años 2013 y 2023. La metodología siguió las recomendaciones de Whittemore & Knafl. La calidad de los estudios fue evaluada utilizando la herramienta CASPe (Critical Appraisal Skills Programme Español). Resultados: Seis artículos, de los 403 iniciales, fueron incluidos en la revisión. La principal barrera que encuentra este colectivo son los problemas de comunicación asociados a la falta de intérpretes de lengua de signos o de profesionales formados y el principal apoyo las ayudas recibidas por parte de los profesionales sanitarios y familiares. Sin embargo, este apoyo, en algunos casos, se percibió como una barrera. Conclusiones: Las mujeres sordas necesitan más apoyo con la lactancia materna. La comunicación accesible puede ayudar a este colectivo a alcanzar sus objetivos de lactancia y, aunque se trata de un requerimiento legal, no siempre es proporcionado.

Published: October 2024

It is widely agreed that collaboration with people with lived experience of specific health conditions or health services is both a moral imperative and a utility to improve research quality, validity and impact. However, there is little agreement about how to practise public involvement. In this article, we describe the formation and work of the Nottingham Maternity Research Network, an ongoing research reference panel that supports public involvement in maternal health research. Drawing on nine years’ experience, researchers and public contributors reflect together on the key issues to consider when co-producing research with maternity service users: first, pragmatic considerations, and second, creating a safe space for drawing on intimate and sometimes traumatic experiences. We argue that a sustained model of public involvement and engagement – that is, a standing group rather than a series of project-based, time-limited opportunities for involvement – brings opportunities to build trust and to develop a community that is supportive and inclusive. However, the sustained model of public involvement also brings practical challenges.

Objective. To create a multifactorial model for predicting the risks of developing clinically significant frontal imbalance in surgical treatment of severe idiopathic scoliosis based on the identification of predictors influencing the main clinical parameters of trunk asymmetry.

Material and Methods. The results of surgical treatment of 288 patients with severe forms of idiopathic scoliosis with a primary thoracic scoliotic curve of types 1, 2, 3 according to Lenke (mean 97.6° ± 15.5° according to Cobb) who underwent surgery in 1999–2019 using posterior segmental instrumentation with hook, hybrid and transpedicular fixation, were analyzed. There were 243 female (84.4 %) and 45 male patients (15.6 %). The average age of patients at the time of surgery was 15.3 [10–39] years. The average postoperative follow-up period was 3.5 [2.0–19.5] years. The analysis included clinical and radiological data obtained in the preoperative, postoperative and late postoperative periods. Predictors of the occurrence of frontal imbalance (the distance from the plumb line to the navel and intergluteal fold more than 15 mm, the tilt of the shoulder girdles more than 5° and the tilt of the scapula more than 15°) were identified by building single- and multivariate logistic regression models.

Results. In the total cohort, 41 (14.2 %) patients with clinically significant frontal imbalance were identified, including 10 (3,0 %) – with an increase in the distance from the plumb line to the umbilicus of more than 15 mm, 12 (4.2 %) – with an increase in the distance from the plumb line to the intergluteal fold of more than 15 mm, 8 (2.8 %) – with a shoulder girdle tilt of more than 5°, and 11 (3.8 %) – with a scapular tilt of more than 15°. A significant predictor of the risk of developing frontal imbalance was determined as postoperative thoracic scoliotic curve of more than 63°. Multiplicative predictors of the risk of frontal imbalance were identified: postoperative increase in the distance from the plumb line to the umbilicus by more than 15 mm and a tilt of the shoulder girdles by more than 5° with a sensitivity of 88.9 % and 100.0 %, and a specificity of 89.5 % and 100.0 %, respectively (p < 0.001).

Conclusion. Identification of multiplicative predictors of the risk of frontal imbalance allows predicting the risk of increasing the distance from the plumb line to the navel by more than 15 mm and the risk of shoulder girdle tilt by more than 5°. To eliminate the risk of frontal imbalance, it is necessary to strive for maximum correction of the thoracic scoliotic curve. When planning surgical treatment using transpedicular fixation for the correction of severe thoracic scoliosis, it is necessary to take into account the patient’s gender and the presence of concomitant neurosurgical, cardiological and pulmonological pathology to prevent shoulder girdle imbalance.

Objective. To analyze the dynamics of pain syndrome, quality of life and functional status of patients with unstable atlas fractures after C1-ring osteosynthesis.

Material and Methods. Study design: observational retrospective case series study (n = 15). The intensity of pain syndrome was assessed using the VAS scale before surgery, 3 days, and 3 and 6 months after surgery. The quality of life was assessed using the Neck Disability Index (NDI) before surgery, and 3 and 6 months after surgery. Functional status, as well as cervical spine range of motion (head turn left/right, flexion/extension) was assessed 3 and 6 months after surgery. The integrity of the atlas bone ring and the degree of fusion after fixation were assessed using axial CT scans; and the lateral mass separation was assessed using frontal CT scans. The criterion for transverse ligament injury was a separation of lateral masses of more than 8.1 mm.      

Results. All patients had C1 fractures type 3B according to Gehweiler, out of them 7 patients (46.7 %) had traumatic injury to the atlas transverse ligament according to Dickman type 1, and 8 patients (53.3 according to Dickman  type 2. The average age of patients was 40 years (12; 71), the male/female ratio was 2/1. In 7 patients (46.7 %), the cause of injury was diving, in 6 (40.0 %) it was a traffic accident, and in 2 (13.3  %) – a fall from a standing height. Observation of patients revealed a positive dynamics in the form of statistically significant regression of pain according to VAS before and 6 months after surgery from 6.8 (6.0; 8.0) to 1.0 (1.0; 0.0) points (Z = -3.434; p = 0.001). A positive trend was also noted in the form of a decrease in NDI scores and an improvement in the quality of life after 3 (Z = -3.411; p = 0.001) and 6 months after surgery (Z = -3.410; p = 0.001). The range of motion (turn left/right, flexion/extension) increased statistically significantly by the 6th month after C1-ring osteosynthesis, and its indicators were close to physiological ones. Postoperative CT scans showed positive dynamics in the form of statistically significant regression of the  lateral mass separation from 10.4 mm (8.9; 11.4) to 2.2 mm (1.8; 2.6); Z = -3.408; p = 0.001. Complete fusion of the atlas fracture was observed after 12.5 months (8.5; 16.5).

Conclusion. Isolated posterior osteosynthesis of the atlas ring for Gehweiler type 3B injury using a repositioning compression maneuver under distraction conditions is physiologically justified. It is a reliable method of stabilization, ensures the restoration of congruence and the entire range of motion in the atlanto-occipital and atlantoaxial joints and stability of the occipital-atlantoaxial complex. This operation contributes to a considerable and long-term reduction in the intensity of pain syndrome and a significant improvement in the quality of life.
The Wake of HCE in Shaun the Postman: Duality, Sameness and Universality in James Joyce’s Finnegans Wake
Authors: García-Madrid Alberto García
Published: October 2024

James Joyce’s Finnegans Wake constitutes one of the highest artistic expressions of modernist literature in the English language. The novel’s departure from realist conventions and its intricate language invite challenging interpretations, fostering an exploration of the narrative in terms of an imitation or reimagination of reality. The distinctive nature of the protagonist’s family, embodying real and metaphorical elements, suggests a potential fusion among the different members. In this regard, this paper focuses on the interpretation of the main male characters – father and sons – as both diverse entities and a unified presence simultaneously, and on the potential rebirth of HCE into Shaun, revealing this fatherly-filial connection especially in the concluding chapters. Central to this exploration is the examination of the concept of “duality”, shedding light on the amalgamation and reimagining of characters into these separate and unified identities. The interplay of characters, particularly the twins, is interpreted as facets of a singular entity, portraying HCE embodying both and affiliating with various characters representing Shaun. Ultimately, the paper aims to unravel the complexities of HCE’s transformation into his son by dissecting the intricacies of duality, sameness and universality throughout the novel.

Contesting the public interest in AI governance
Authors: Cohen Tegan , Suzor Nicolas P.
Published: October 2024

This article argues that public contestability is a critical attribute of governance arrangements designed to align AI deployment with the public interest. Mechanisms to collectively contest decisions which do not track public interests are an important guardrail against erroneous, exclusionary, and arbitrary decision-making. On that basis, we suggest that efforts to align AI to the public interest through democratic participation will benefit substantially from strengthening capabilities for public contestation outside aggregative and deliberative processes. We draw on insights from democratic and regulatory theory to explore three underlying requirements for public contestability in AI governance: (1) capabilities to organise; (2) separation of powers; and (3) access to alternative and independent information. While recognising that suitable mechanisms for contestability will vary by system and context, we sketch out some possibilities for embedding public contestability in AI governance frameworks with a view to provoking further discussion on institutional design.
Navigating data governance risks: Facial recognition in law enforcement under EU legislation
Authors: Gültekin-Várkonyi Gizem
Published: October 2024

Facial recognition technologies (FRTs) are used by law enforcement agencies (LEAs) for various purposes, including public security, as part of their legally mandated duty to serve the public interest. While these technologies can aid LEAs in fulfilling their public security responsibilities, they pose significant risks to data protection rights. This article identifies four specific risks associated with the use of FRT by LEAs for public security within the frameworks of the General Data Protection Regulation and Artificial Intelligence Act. These risks particularly concern compliance with fundamental data protection principles, namely data minimisation, purpose limitation, data and system accuracy, and administrative challenges. These challenges arise due to legal, technical, and practical factors in developing algorithms for law enforcement. Addressing these risks and exploring practical mitigations, such as broadening the scope of data protection impact assessments, may enhance transparency and ensure that FRT is used for public security in a manner that serves the public interest.

I am especially grateful to Bonnie Lawlor and Fabienne Meyers for their assistance with this project and more broadly their work in support of IUPAC and chemists globally. I hope that you will enjoy these pieces, and I look forward to collecting more responses from other YOs as we continue this globally engaged collection!
Asymmetrical Monetary Relations and Involuntary Unemployment in a General Equilibrium Model
Authors: Piluso Nicolas
Published: October 2024

This article aims to model Keynesian involuntary unemployment within the framework of Walrasian general equilibrium, incorporating an additional hypothesis: the possibility of credit restrictions by banks or financial intermediaries. Keynes’s theory of involuntary unemployment is based on the rejection of the “second classical postulate,” which leads to the idea that entrepreneurs alone decide the level of employment. This is what some Keynesians call the asymmetry of the wage relationship. The result is a restriction of Walras’ law, which no longer includes the labor market. However, the problem is that entrepreneurs themselves may find themselves constrained by financial intermediaries. If there is a second type of asymmetry, i.e., between banks/financial intermediaries and entrepreneurs, Walras’ law will be doubly restricted since it will also exclude the credit market. I set out to identify the consequences of the properties of involuntary unemployment in a general equilibrium model.
Topical treatment of adult house flies, Musca domestica L. (Diptera: Muscidae), with Beauveria bassiana in combination with three entomopathogenic bacteria
Authors: Johnson Dana M. , Weeks Emma N. I. , LoVullo Eric D. , Geden Christopher J.
Published: October 2024

Biological control of house flies, Musca domestica L. (Diptera: Muscidae) has the potential to improve the efficacy and sustainability of integrated pest management. In a previous study, we demonstrated that three bacteria species (Serratia marcescens Bizio [Enterobacteriales: Enterobacteriaceae], Photorhabdus temperata Fischer-Le Saux et al. [Enterobacteriales: Enterobacteriaceae], and Pseudomonas protegens Ramette et al. [Pseudomonadales: Pseudomonadaceae]) are extremely virulent, inducing rapid morbidity and high mortality in adult house flies when injected into the hemocoel but show little effect when applied topically. Here we tested the hypothesis that topical application of these species in combination with the entompathogenic fungus Beauveria bassiana (Bals. Criv.) Vuill. (Hypocreales: Cordycipitaceae) would result in an increased and rapid mortality if fungal penetration of the fly cuticle allowed for increased delivery of the bacteria into the fly hemocoel. Bacteria and B. bassiana were tested either by application at the same time or by sequential application of the two pathogens 48 h apart. Results indicated little evidence for synergy between B. bassiana and any of the bacterial pathogens. However, P. protegens caused early mortality (<50 % at 3 days) when applied alone and in combination with B. bassiana. A modified disc diffusion assay indicated that P. temperata and P. protegens had inhibitory effects on the vegetative growth of B. bassiana suggesting the release of antifungal molecules by the bacteria. Results with P. protegens were sufficiently encouraging to warrant further investigation of this species and its associated toxins as house fly biological control tools.

Purpose

The current work presents a theoretical framework to boost heat transmission in a ternary hybrid nanofluid with homogeneous and heterogeneous reactions in the conical gap between the cone and disk apparatus. Furthermore, the impacts of non-linear thermal radiation on the ternary hybrid nanofluid composed of white graphene, diamond, and titanium dioxide dispersed in water are analyzed.

Originality/value

The combination of cone and disk systems is crucial for designing efficient heat exchange devices in the field of biomedical science for various purposes. For instance, in medical devices, the cone–disk apparatus is used to study the flow and heat transfer characteristics for better design and functionality. Hence, a sincere attempt has been made to study the impact of homogeneous and heterogeneous reactions on the nanofluid flow between the cone and disk in the presence of non-linear thermal radiation.

Design/methodology/approach

The mathematical model’s governing equations are partial differential equations (PDEs) which are then transformed into non-linear ordinary differential equations through appropriate similarity transformations. These transformed resultant equations are approximated by the Runge–Kutta–Fehlberg fourth/fifth order (RKF45) technique. The influence of essential aspects on the flow field, heat, and mass transfer rates was analyzed using a graphical representation.

Findings

The interesting part of this research is to discuss the power of parameters in three cases, namely, (1) rotating cone/disk, (2) rotating cone/stationary disk, and (3) stationary cone/rotating disk. Furthermore, the thermal variation of the fluid is analyzed by an artificial neural network with the help of the Levenberg–Marquardt backpropagation algorithm. The regression analysis, mean square error, and error histogram of the neural network are analyzed using this algorithm. From the graph, it is perceived that the flow field climbed up significantly with an increase in the values of radiation parameters in all cases. Also, it is noticed that temperature upsurges significantly by upward values of solid volume fraction of the nanoparticles (

Pullback and uniform exponential attractors for non-autonomous Oregonator systems
Authors: Liu Na , Yu Yang-Yang
Published: October 2024

We consider the long-time global dynamics of non-autonomous Oregonator systems. This system is a coupled system of three reaction-diffusion equations, that arises from the Belousov-Zhabotinskii reaction. We first present some sufficient conditions for the existence of pullback and uniform exponential attractors for non-autonomous dynamical system. Then, we apply abstract results to prove the existence of a pullback exponential attractor for Oregonator systems affected by time-dependent forces and a uniform exponential attractor for Oregonator systems driven by quasi-periodic external forces.

Published: October 2024

In today’s world, the use of paper and cardboard increasing but the availability of raw materials and the environmental impact on the paper industry is a big concern. To address these concerns, researchers are exploring the potential of agricultural waste products as raw materials for pulp production. This study uses morphological, chemical composition, FTIR, XRD, and thermogravimetric analysis to examine the potential of banana pseudo-stem as a raw material for paper pulp to address environmental concerns and raw material shortages in the paper industry. The study reveals favorable characteristics for papermaking, including long fiber length (1750 μm), thin cell wall thickness (9.7 μm), and large lumen diameter (22.15 μm). The chemical composition of banana pseudo-stem contains cellulose (44.93 %), hemicellulose (23.7 %), and Klason lignin (11.1) showing its suitability for pulp production. FTIR analysis highlights the functional groups present on the banana pseudo-stem. The XRD analysis shows that it has a similar cellulosic peak and crystallinity index with common raw materials used in pulp production. The thermogravimetric analysis shows that the banana pseudo-stem has high thermal stability. The findings demonstrate that banana pseudo-stem, both by itself and in combination with other raw materials, might be a potential raw material for the pulp production.
Does Advertising Facilitate Supplier-Provided Trade Credit?
Authors: Farooq Omar , Saleem Kashif
Published: October 2024

Using the data of non-financial firms from India, the paper finds that firms with large advertising budget tend to receive more trade credit from their suppliers than firms with low advertising budget. The findings are consistent with the assumption that advertising reduces information asymmetries, builds brand image, and improves firm performance. All of these factors facilitate the access to trade credit. The findings of this paper hold after numerous sensitivity checks.
Management of follicular thyroid carcinoma

Published: October 2024

Follicular thyroid carcinoma (FTC) is the second most common histological type of thyroid carcinoma. This review aims to summarize the available evidence and guidelines and provide an updated consensus regarding the management of FTC. The cytoarchitectural features of FTC are similar to those of follicular adenoma (FA), and it is difficult to preoperatively distinguish between FA and FTC. For nodules with Bethesda class III–V cytology, molecular test results (if available) should be considered before the operation. However, it should be noted that molecular tests are not available in all countries. The goals of initial surgical therapy for patients with FTC are to improve overall and disease-specific survival, reduce the risk of persistent/recurrent disease and associated morbidity, and permit accurate disease staging and risk stratification while minimizing treatment-related morbidity and unnecessary therapy. Previous studies have reported some prognostic factors such as distant metastasis, age, tumor size, vascular invasion, TERT promoter mutation, and histological subtype. In particular, the degree of vascular invasion is becoming increasingly important. Evaluating these prognostic factors is essential for prognostic prediction and precise management of patients with FTC. Recurrence and distant metastasis of FTC are treated with radioactive iodine (RAI). However, some FTCs become refractory to RAI. Multi-tyrosine kinase inhibitors such as sorafenib and lenvatinib are utilized for treating RAI-refractory FTCs. In addition, given that renin–angiotensin system (RAS) is the most common driver gene for FTC, it is also important to develop RAS inhibitors.
De la prensa al diccionario. El tratamiento de los préstamos en el columnismo lingüístico a partir del Diccionario de voces de uso actual
Authors: Marimón Llorca Carmen , Santamaría Pérez Isabel
Published: October 2024

Con el Diccionario de Voces de Uso Actual (DVUA) se abrió una nueva línea de investigación lexicográfica que contribuyó a mejorar la descripción sincrónica de la lengua española. La novedad de esta obra era que daba entrada a palabras no registradas en el léxico oficial representado por el diccionario académico, pero que sí estaban documentadas en la prensa nacional. Muchas de estas voces eran neologismos o préstamos de uso corriente y habitual en el español del momento. Este diccionario venía a recoger una inquietud sobre la renovación del vocabulario español que, desde mediados de los años ochenta, el columnismo lingüístico había hecho evidente también a través de sus trabajos en prensa. El objetivo de este trabajo es analizar el tratamiento que columnistas y el DVUA y en el Nuevo diccionario de voces de uso actual (NDVUA), junto con otros diccionarios descriptivos y normativos del español, dan a los neologismos, principalmente de procedencia extranjera. Para ello se ha examinado el concepto de neologismo y la actitud que hacia este tipo de vocablos muestran los columnistas y el DVUA para, posteriormente, realizar un cotejo que muestre el nivel de coincidencia entre las voces registradas en las columnas sobre la lengua (CSL), las incluidas en el DVUA y las que finalmente, acabarán formando parte del Diccionario de la RAE. Se concluye que el DVUA supuso un punto de inflexión hacia una lexicografía descriptiva, con una postura flexible y conectada con la realidad cambiante del español que era, asimismo, la que mostraban las columnas.

The authors address a relevant problem connected with digital transformation of the mining industry toward import substitution and creation of a barrierless technology to operate digital data and models of objects of a mining technology with a view to solving tasks in geology, surveying and engineering. An important component of a barrierless technology is a single virtual digital space for the database translation when using program products based on different object models. Such technology is implementable through formation of a digital platform containing a basic function to operate object models in digital space and API-functions to integrate the created tools into this digital space. The requirements of the digital platform are to the largest degree met by the program products of mining and geological information systems. In the digital space of such systems, 3D modeling is performed and basic mining and geological problems are solved. The article formulates the main functionality standards of such digital platform and describes the current situation in creation of the platform using the mining and geological information system (MGIS) MINEFRAME at the Mining Institute, KSC RAS, and at MINEFRAME Laboratory LLC.

Erotikos ir pornografijos reguliavimas viešojoje sferoje nepriklausomybę atkūrusioje Lietuvoje: Vilniaus atvejis (1990–1996)
Authors: Bėčiūtė Kotryna
Published: October 2024

This article examines the state control of erotica in the public sphere and the activities of regulatory institutions in Lithuania between 1990 and 1996. Based on archival documents, the study reveals the methods used by the Press Control Commission and the Vilnius City Ethics Commission to regulate the distribution of erotica after the restoration of independence, and the criteria used by these institutions to assess sexualized content. A key issue in shaping a coherent legal discourse on the regulation of erotic and pornographic content is the ambiguity and blurring of the terms ‘erotica’ and ‘pornography.’ The study shows that these institutions sought to control erotic content primarily through three argumentative models: 1) the tradition and values model, 2) the “I know it when I see it” model, and 3) the threat of homosexuality model. The findings indicate a strong tendency within the Press Control Commission and the Vilnius City Ethics Commission not only to regulate (e.g., through age limits) but also to eliminate such content. The vague legal rulings and conceptual uncertainties of the 1990s gave these commissions considerable autonomy, allowing them to assume a proactive role that resembles that of an inquisitor or moral policeman.
Eine frühere Redaktion des l. Litauischen Statuts
Authors: Gudavičius Edvardas
Published: October 2024

Die Zamojski-Abschrift des 1. Litauischen Statuts zeichnet sich, als ein Arbeitsexemplar des Kanzlers, mit den besonderen Eigenschaften aus: jede ihrer Statutsabteilungen besteht aus einem gesonderten Papierbogen. Die Bogen der 9., 12., 13., zum Teil auch 8. Abteilung haben das älteste Papier. Die Artikeltitel im Text und im Register unterscheiden sich im Allgemeinen nicht. Eine Ausnahme bildet die 9. Abteilung und diese Unterschiede gehen auch aus der Grundredaktion in die lateinische und erweiterte Redaktion des Statuts über (das bezeugt, dass das Register der 9. Abteilung sich früher als die anderen Register entstand). Die ersten Worte des 1. Artikeltitels der 8. Abteilung sind: „Zum Ersten beginnt es sich mit der Entscheidung des Königs mit der Unterschrift der eigenen Hand Seiner Gnade ...“, was die Bestätigungsformel anweist. Alle diese Zeichen erlauben, die 8., 9., 12. und 13. Abteilungen als eine Sondergruppe anzusehen. Die Artikelthematik dieser Gruppe ist sehr der Thematik des Rechtsbuchs von Kasimir (1468) ähnlich. Die Bestätigungsspuren (die Unterschrift des Großfürsten) dieser Gruppe und ihre frühere Einschreibung in das Exemplar des Kanzlers lässt sie für eine Anfangsredaktion des 1. Statuts, welche später erweitert wurde, halten.
Frau im Rechtsalltag von Vilnius und Kaunas in der ersten Halfte des 16. Jhs: Zeichen des modem werdenden Lebens
Authors: Karpavičienė Jolanta
Published: October 2024

Die Forschungen der Frauengeschichte gewinnen in den letzten Jahren in Litauen an Intensität. Aber noch wenig ist das Thema über die Stellung der Frau in den litauischen Städten des Spätmittelalters und zu Beginn der Neuzeit erforscht. Auf Grund der Materialien von Metrik Litauens und von altem Kaunasser Archiv wird im Artikel die Frage über den Status der Frau im Rechtsleben der größten Selbstverwaltungsstädte Litauens untersucht.  Obwohl historische Quellen davon zeugen, dass in Kaunas und Vilnius das Prinzip der Geschlechtsvormundschaft über die Frau bekannt wurde, zeigt die ausführlichere Untersuchung der erwähnten Urkunden, dass diese Regel des mittelalterlichen Rechts in Litauen allgemein und konsequent nicht angewandt wurde. Anhand der deutschen Historiographie und der Analyse sächsisch-magdeburgischer Rechtsquellen werden im Artikel das Wesen sowie der Wandel dieses Rechtsprinzips behandelt. Man kommt zum Schluss, dass dieses Prinzip Litauen zu jener Zeit erreicht hat, als es in Europa schon die innere Transformation erfahren hat und allmählich beseitigt wurde. Wegen des Phänomens der „verspätenden Geschichte Litauens“ wurde in den litauischen Städten mehr die äußere Gestalt des Prinzips und nicht sein Inhalt übernommen. Die Vertretung der Frau vor dem Gericht durch ihren Ehemann oder einen männlichen Verwandten wurde nicht als eine obligatorische Bedingung betrachtet, sondern als eine günstige Voraussetzung angesehen, um die Vermögensrechte der Städterin zu realisieren.  Es ist festzustellen, dass das Vertretungsprinzip der Frau vor dem Gericht in Vilnius und Kaunas nicht von beschränkter Handlungsfähigkeit der Frau, sondern von der Intensität des städtischen Rechtslebens sowie dem Wachstum der Rechtskultur in der Stadt zeugt. Dieser modern werdende Rechtsgang bildete gute Voraussetzungen für rechtliche Aktivität der Frau in der Stadt.  Der breitere Kontext des Rechtslebens in Vilnius und Kaunas in der ersten Hälfte des 16. Jhs lässt behaupten, dass die Frau aus dem Rechtsverkehr der Stadt nicht ausgeschlossen wurde. Die zahlreichen Beispiele zeugen davon, dass die Bewohnerinnen der Städte ziemlich oft ihre Angelegenheiten in den Selbstverwaltungsinstitutionen oder in den Ämtern der staatlichen territorialen Verwaltung, die auch in den Städten residierten, ohne Begleitung der Männer erledigten. Die Frauen konnten selbständig sich über Gewalt, materiellen Schaden, Beleidigung beklagen, Vermögensgeschäfte abschließen, manchmal sogar im Namen ihres Mannes prozessieren. Niemand bezweifelte die Möglichkeit der Frau, Eid zu leisten, Zeugin zu sein, sich für andere Personen zu bürgen. Die Untersuchung lässt schlussfolgern, dass eben die Stadt eine passende Umgebung für die rechtliche Aktivität der Frau war.
The Question of Rusian Nobily Existence from the Second Half of 19th Century to the Beginning 20th Century
Authors: Gaidis Ryšard
Published: October 2024

Der vorliegende Artikel befasst sich mit einer der wichtigsten Fragen der politischen Geschichte des Russischen Imperiums in der Zeit von der zweiten Hälfte des 19. Jh. bis zum Anfang des 20. Jh., und zwar mit der politischen Rolle des russischen Bojarentums. Dieses Problem ist auch für die Geschichte Litauens von großer Bedeutung, denn seine Analyse hilft, die politischen Positionen des litauischen Adels im Russischen Imperium zu erschließen. Zum vollen Erfassen des politischen Gewichts des litauischen Adels im Russischen Imperium muss die Spezifik des politischen Einflusses seitens des russischen Bojarentums erläutert werden.  Das politische Modell des russischen Bojarentums kann auf Grund der russischen historiografischen Quellen aufgebaut werden. Im Sinne der Faktographie sind die in den 70er und 80er Jahren herausgegebenen Werke der sowjetrussischen Historiker (J. Solowjow, W. Djakin, A. Korelin u. a.).  Nach der Aufhebung der Leibeigenschaft in der zweiten Hälfte des 19. Jahrhunderts (im Jahre 1861) hat der russische Adel einen Teil seiner Privilegien und Sonderrechte auch in anderen gesellschaftlichen Bereichen des Lebens eingebüßt. Dies hinderte aber das Bojarentum nicht daran, das politische Leben des Staates weiterhin auf mehrere Weisen mitzubestimmen. Der einflussreichste Teil des russischen Bojarentums, und zwar die Grundherren und der Adel, bekleideten weiterhin hohe Posten in den staatlichen Behörden und in der Armee. Die politischen Ideen des Bojarentums kamen auch in solchen nichtpolitischen Behörden zum Ausdruck wie Landstände und Semstwos (lokale Selbstverwaltungsorgane).  Der russische Adel strebte danach, nicht nur seine Sonderposition in der Gesellschaft zu erhalten, sondern auch die Staatspolitik mitzubestimmen. Den Imperatoren wurde mehrmals vorgeschlagen, auf der Staatsebene eine Institution von Adeln und Semstwos zu berufen, die als ein Beratungsorgan bei der Lösung von wichtigsten Angelegenheiten der Stände und der lokalen Selbstverwaltungsorgane fungieren und sogar die Beschlüsse der Regierung mitbestimmen sollte.  Politisch gesehen war die Lage des russischen Bojarentums bis zur Revolution vom Jahre 1905 zweideutig. Einerseits verstand der Adel, dass er als traditionelle Gesellschaftsschicht die Aufhebung der Monarchie nicht zulassen darf, deshalb suchte er Unterstützung beim Imperator und unterstützte auch seinerseits dessen Macht. Die wandlungsreiche politische, gesellschaftliche und wirtschaftliche Situation des Staates trug allerdings dazu bei, dass die Adligen von einer liberalen Gesinnung die vom Staat initiierten Reformen unterstützten und darauf hofften, neue Möglichkeiten zu bekommen, sich auf diese oder jene Weise am politischen Leben des Staates zu beteiligen.

Published: October 2024

O presente estudo abordou a pesquisa da pós-graduação stricto sensu brasileira sobre o uso de dramatizações em contextos educacionais. A análise proposta foi direcionada para a seleção de teses e dissertações indexadas na Biblioteca Digital Brasileira de Teses e Dissertações (BDTD). Mediante a investigação de 19 teses e dissertações, destacou-se a concentração da publicação de trabalhos nos anos de 2018 e 2020. Constatou-se que 16 IES têm atuado na elaboração de estudos sobre o uso de dramatizações para fins educacionais. Também se sublinhou o maior percentual de trabalhos oriundos de programas acadêmicos (63,15%) das às áreas de Ensino e de Educação. Constatou-se o maior percentual de pesquisas que abordam a utilização de dramatizações no Ensino Médio (36,8%). Compreendeu-se que a heterogeneidade e a predominância de amostras inferiores a 100 participantes estão intrinsecamente vinculadas à adoção de uma abordagem qualitativa pelo maior quantitativo de trabalhos. Por fim, ressaltou-se a contribuições da implementação de dramatizações para o aumento da participação e da motivação discente, a melhoria das experiências comunicativas e da contextualização dos conteúdos.

Revealing the Genetic Differentiation of Rattus norvegicus (Berkenhout 1769) Populations by Analyzing Two Mitochondrial Markers
Authors: Çetintürk Derya
Published: October 2024

Rattus norvegicus (Brown rat) has a great importance for public health and economy because it lives in close association with human populations. However, molecular systematic studies on global populations of R. norvegicus are very few. In this study, sequences obtained from Europe, Asia, Africa, and America regions were analyzed using mitochondrial Cytochrome-b and Cytochrome oxidase-I gene regions and genetic differentiation levels between these populations were revealed. Accordingly, samples belonging to the studied populations did not split in Bayesian Inference trees and Median-joining networks; these samples also formed common haplotypes, and mean genetic distance and fixation index values were generally low. The results of the study showed that gene flow between these populations may be continuing due to the transportation activity by humans.
