Authors: Balbino Marina , Montatore Manuela , Masino Federica , Carpagnano Francesca A. , Guglielmi Giuseppe
Published: October 2024

We describe a rare case of secondary breast angiosarcoma in a 72-year-old woman with a history of breast cancer who presented to our clinic with a painless palpable mass in the outer upper quadrant of the left breast. The diagnosis required a multidisciplinary approach involving a senologist, anatomopathologist, and oncologist. Imaging modalities such as mammography, ultrasonography, and magnetic resonance imaging made it possible to assess the extent of the tumor, lymph node involvement, and distant metastases. The diagnosis was confirmed by a tissue biopsy. Herein, a rare case is presented, with the main educational purpose of describing the clinical presentation and complex diagnostic evaluation and discussing the differential diagnosis and management. Indeed, secondary mammary angiosarcoma is a rare and aggressive neoplasm, and understanding its unique features is essential for clinical decision-making and patient outcomes. The tumor has a worse prognosis because of its late diagnosis, higher risk of rapid distant spread, and limited treatment options. Such cases require close monitoring, aggressive strategies, and supportive care.

The study focuses on pancreatic cancer (C25), a malignant neoplasm arising from the ductal epithelium or glandular tissue of the pancreas, which accounts for 3% of the overall cancer incidence in Russia. The rates of incidence and mortality are rising, with the number of newly registered patients in Russia being lower than the number of recorded deaths, although the one-year mortality rate among patients is decreasing. The direct cause of pancreatic cancer (C25) remains unknown. Risk factors for developing this condition include genetics, smoking, alcohol abuse, a sedentary lifestyle, excessive meat consumption, and a lack of plant-based foods in the diet. Diseases associated with a high risk of this pathology include long-standing chronic pancreatitis, newly diagnosed type 2 diabetes in individuals aged 50-70, and cystic neoplasms of the pancreas. The aim of the study is to examine the patterns of incidence and mortality, the quality of patient registration, the characteristics of tumor localization, and the histological structure of pancreatic cancer (C25). The study will also track the nature of annual mortality among patients and explore the possibilities, methods, and techniques of modern diagnosis and treatment for these patients. The research confirmed the significant burden of pancreatic cancer (C25), primarily due to the late detection of this disease. The study provided sufficient material to analyze age-related risk factors, as well as the patterns of incidence and mortality in the population. It also examined and presented mortality rates among patients, including during the first year of observation.

Authors:   , Khuc Quynh Thi , Finamore Troy
Published: October 2024

Prior research into website response times suggests that feedback can help mitigate aversions to delays. While studies have been conducted on using progress indicators as a form of feedback, this body of literature focuses exclusively on the comparative analysis and visual design of individual progress indicators. To address the gap in the existing literature, this research project investigates how combinations of 4 different progress indicators affect users' perceived wait time during online delays. Through a comprehensive analysis of survey data collected from 134 participants, we were able to compare the perceived wait time and user preference of 7 feedback combinations. Our findings reveal that "Looped Animation + Skeleton Screen" is most effective in shortening users' perceived wait time. While combinations that include the skeleton screen can generally lead to faster perception, combinations with percent-done animation can offer more clarity and transparency. We hope that this study contributes to the larger research base by offering valuable insights into the effectiveness and use cases for different feedback combinations during online delays.

Authors:   , Ladson Nia Freedom , Grant Kristine
Published: October 2024

While considerable research has explored why Black teachers leave the classroom, there is limited understanding of why they choose to stay. This hermeneutic phenomenological study aimed to investigate Black teachers' experiences in public schools and the factors contributing to their retention. Twenty Black teachers from across the United States participated, with data sources including interviews, questionnaires, and resumes, analyzed using first and second-cycle coding. Four themes emerged from the data analysis: 1) "Race in America is always something to navigate, especially in Schools" - Black Teachers, Racist School Environments; 2) "I don't have any support" - Black Teachers, Diminished School Support; 3) "The money and job stability keep me here..." - Black Teachers and Financial Stability; and 4) "Black Joy as an educator is operating in my most Authentic Self" - Black Joy for Black Teachers. From these four themes, five major results were identified: Result #1: Despite experiencing and witnessing racism in their schools, study participants remained in the profession. Result #2: Despite a lack of support from their school and district leaders, study participants remained in the profession. Result #3: Despite low salaries, study participants remained in the profession. Result #4: While study participants remained in the profession despite the challenges of racism, lack of support, and low pay, they did seek out better working conditions by changing schools. Result #5: Despite the adverse challenges named participants consistently cite their care for and cultural commitment to historically underserved students and communities as the primary reasons why they stay in the profession. This research underscores the significance of retaining Black teachers, revealing that various factors influence their decision to remain in the profession. Despite facing racism, inadequate support, and low pay, Black teachers stay in the workforce as an expression of love, commitment, and a desire to nurture Black joy. Recommendations for practice and future research are provided.
The Multifaceted and Paradoxical Roles of Toll-like Receptors and Their Signaling Adaptors in Modulating Microglia Innate Immune Response to Neurotropic Betacoronaviruses
Authors:   , Davis Elijah , Navas-Martin Sonia
Published: October 2024

Despite recent advances in medicine, viral infections of the central nervous system (CNS) constitute 20% of diagnosed neurological disorders. Left untreated, these infections can prove fatal and up to 50% of survivors develop long-term neurological complications. Inappropriate inflammation is considered the hallmark of CNS disease. Thus, understanding the mechanisms underlying virus-associated neuroinflammation, also known as viral encephalitis (VE), is crucial for the development of neuroprotective treatments. Microglia, CNS-resident innate immune cells, play a pivotal role in limiting viral replication within the CNS, protecting against lethal VE, and mediating neuronal repair. However, direct infection or aberrant activation can dysregulate microglia activity and generate a pro-inflammatory microenvironment that promotes neurotoxicity, worsening neuropathogenesis. In this study, we demonstrate in vitro that microglia facilitate the replication of Mouse Hepatitis virus (MHV) A59 and -JHM, neurotropic beta coronaviruses that model acute VE with or without chronic demyelination. Efficient MHV infection was partially dependent on Toll-like receptor (TLR) -2, -3, -4, and -7 signaling and deficiency these receptors reduced viral titers, protein production, and double-stranded RNA synthesis. This suppression was more pronounced in microglia expressing nonfunctional TLR signaling adaptors, which disrupts multiple TLR pathways. Mechanistically, we show that the refractory nature of adaptor-deficient microglia is partially mediated by amplified IFN[beta] responses. ELISA and microarray analyses of the innate immune secretome revealed that TLRs were the primary regulators of microglia secretory responses during MHV infection, though the role of each TLR greatly varied. Given that peripheral viral infections may be linked to lipopolysaccharide (LPS)-induced neuroinflammation, we investigated how LPS exposure influenced microglial immune responses to MHV. Stimulation with TLR4-specific LPS prior and/or after viral adsorption significantly impaired MHV replication through the induction of IFN [beta]. Surprisingly, pharmacological TLR4 inhibition similarly restricted MHV replication while elevating IFN [beta] expression. Remarkably, LPS stimulation increased expression of the cytosolic dsRNA sensor melanoma differentiation-associated protein 5 (MDA5) and activated the endosomal dsRNA sensor TLR3. TLR3 signaling was demonstrated to selectively contribute to LPS-induced inflammation and was required for the upregulation of MDA5 during MHV infection. Taken together, these novel discoveries unveil a complex and interconnected microglial PRR network that can either antagonize or promote MHV replication while also modulating neuroinflammation during acute and peripheral disease.

Abstract: This study examines the differences in students' communication skills between cooperative and collaborative learning at SMPN 24 Malang, Indonesia. The study uses a qualitative method with a case study approach to explore how students' communication skills are manifested in real learning situations. Data were collected through in-depth interviews and direct observation, then analyzed using a descriptive qualitative method. The findings indicate that students in collaborative learning tend to be more open and active in communication, while those in cooperative learning are more passive and experience limitations in communication skills. Factors influencing communication skills include self-confidence, motivation, personal relationships, and perceptions of other group members. The study suggests that teachers should alternate between cooperative and collaborative approaches and assist students in overcoming negative perceptions that may hinder communication skills within the group
Fullerenes in dentistry: A review on unlocking their therapeutic potential in oral medicine
Authors: Khan Fatima Injela , Aggarwal Ashish , Upadhyay Nitin , Vishnurao Sowmya Gujjar , Jha Navendra
Published: October 2024

Fullerenes are a family of carbon allotropes that have demonstrated great potential in oral medicine. They have a distinct cage-like structure and take the shape of hollow spheres, ellipsoids, or tubes with special structural and physicochemical features. When fullerenes are spherical, they are known as buckyballs, and when they are cylindrical, they are known as carbon nanotubes or buckytubes. Due of their flexible construction, they can be used in a variety of settings, including medication delivery, gene therapy, diagnostics, and oral illness treatment. Fullerenes have the ability to conjugate or encapsulate medicinal substances, allowing for the regulated and targeted administration of drugs to tissues afflicted by diseases including mouth cancer and periodontal disease. When treating infections and long-term inflammatory disorders in the oral cavity, their capacity to improve drug stability and bioavailability is very advantageous. Functionalized fullerenes improve biosensing platforms and imaging methods in diagnostics, facilitating the early detection of illnesses and oral malignancies. There are still obstacles to overcome in order to maximize their biocompatibility, toxicity profiles, and delivery methods for clinical application, despite their enormous potential. This review aims in revolutionizing the detection and treatment of numerous oral disorders, and ongoing research endeavours to fully investigate the therapeutic potential of fullerenes in oral healthcare.

Authors: Kale Preeti , Manasa P , Babu Koppala Ravi
Published: October 2024

Patient safety is an essential aspect of healthcare, including dentistry. Dental Outpatient Departments (OPDs) pose unique challenges, where the risk of infections, procedural errors, and patient discomfort can compromise safety. This review examines patient safety issues in dental OPDs, focusing on common hazards, preventive measures, and evolving strategies to ensure safer care. Infection control, medical emergencies, equipment sterilization, and patient data protection are key concerns. The complex interplay of patient management, dental procedures, and clinician awareness requires robust protocols to mitigate risks. Dental professionals must be vigilant in managing cross-contamination risks, such as through the use of personal protective equipment (PPE) and strict hand hygiene practices. Moreover, regular staff training in handling medical emergencies, such as allergic reactions or fainting, is crucial for effective management.

This article also explores the role of technological advancements in enhancing patient safety, such as digital record-keeping, which minimizes documentation errors, and advanced diagnostic tools that reduce invasive procedures. Additionally, patient-centered approaches, including improved communication and informed consent practices, foster trust and reduce misunderstandings. The implementation of evidence-based guidelines and adherence to professional standards further contribute to a culture of safety. By synthesizing current research, this review aims to highlight best practices for improving patient safety in dental OPDs and underscores the importance of continuous monitoring and improvement in these settings. Addressing these safety concerns is critical not only to improve patient outcomes but also to ensure that dental OPDs remain a safe and trusted environment for all.

Authors: Rathan A C Lakshmi , Sinha Devanshu , Somani Sapna D P , Narayanan Vivek
Published: October 2024

: The mandible is the most durable and only movable bone that constitutes the lower one-third of the face.The mandibular condyle and coronoid processes are two anatomical structures located in the superior portion of the ramus of the mandible. Morphometric understanding of these structures is key to the diagnosis of various disorders associated with the temporomandibular region. It also aids in devising a plan for the management of such disorders.

: The purpose of this study is to evaluate the anatomical corelation between the condyle and coronoid of the mandible.

: This retrospective study was conducted by obtaining 100 high-resolution computed tomography images from departmental archived records between 2018 and 2024. After acquisition, these images were incorporated into MIMICS Materialize software to create stereolithography models, and morphometric analysis was carried out.

Out of 100 HRCT data obtained, 87 were male and 13 were female. There is a statistically significant difference in length and angulation of the coronoid and condyle on both sides. The condyle length for males was (4 ± 5.5 mm) higher than the condyle length of females on both sides. However, the coronoid length of males and females varies in a range of 0.5-2mm on both sides of the mandible.

Understanding the morphological variation of mandibular condylar and coronoid processes aids in various fields of medicine like forensics, anthropology, and reconstructive maxillofacial surgery. Our study inference will aid surgeons in planning coronoid grafts for condylar reconstruction as well as other maxillofacial reconstructions. Additionally, it helps in forensic odontology to determine a person's age and gender.

Published: October 2024

As Tecnologias Digitais de Informação e Comunicação (TDIC) e o Ensino no Brasil estão intimamente ligados. Em 2019, essa conexão se tornou mais evidente com a introdução da Base Nacional Curricular (BCN) para a formação docente, abrangendo graduação e pós-graduação. No entanto, as competências exigidas em TDIC para os professores ainda estão aquém da realidade da formação docente no país. Este estudo se propõe a analisar como as TDICs são integradas em disciplinas de pós-graduação em Ensino no Estado do Rio de Janeiro. Utilizando como metodologia a análise textual de dados da Plataforma Sucupira por meio do software Voyant®, foram identificadas 70 disciplinas em 18 programas de pós-graduação na área de Ensino da CAPES em 12 instituições de pesquisa do estado. Observa-se que a maioria das disciplinas mantém uma abordagem instrumentalista e não acompanha as transformações tecnológicas. Mesmo diante de novas demandas, muitas disciplinas permanecem inalteradas, o que evidencia uma falta de atualização frente aos desafios contemporâneos e às necessidades emergentes, como as causadas pela pandemia.

Authors: Jiménez Uscátegui Mariángela
Published: October 2024

Propósito/Contexto: el presente trabajo tiene como finalidad sumar elementos de reflexión y contribuir al análisis e identificación de los fundamentos que han dado lugar en Colombia al reconocimiento del derecho a la eutanasia de niños, niñas y adolescentes, independientemente de su capacidad legal.
Metodología/Enfoque: se trata de un estudio de índole cualitativo, de reflexión y de revisión de los pronunciamientos jurisprudenciales de la Corte Constitucional de Colombia, entre 1997 y el año 2021, en relación con la autonomía de los menores de edad dentro del marco de la muerte digna y, específicamente, frente a su derecho a decidir sobre un procedimiento eutanásico.
Dentro de la metodología, se realizaron búsquedas en bases de datos como SciELO y Scopus con los tesauros de muerte digna; derechos de niños, niñas y adolescentes; eutanasia y autonomía.
Resultados/Hallazgos: el artículo mostrará que el reconocimiento nacional del derecho a la muerte digna en niños, niñas y adolescentes tiene una gran influencia de estándares foráneos en materia de reconocimiento de derechos y del interés superior del menor, conforme a los instrumentos jurídicos del derecho internacional. En consonancia, la jurisprudencia de la Corte Constitucional ha señalado sobre la materia que los niños, niñas y adolescentes tienen autonomía para la toma de decisiones sobre el derecho a la muerte digna. Lo anterior, pese a no tener capacidad legal conforme a la legislación civil colombiana.
Discusión/Conclusiones/Contribuciones: el artículo evidencia la necesidad de profundizar, reflexionar e, idealmente, armonizar el respeto a la autonomía de niños, niñas y adolescentes que tiene un marco constitucional progresivo, con la normatividad civilista referente a la capacidad legal, debido a que esta última se sustenta en la necesaria seguridad jurídica que entrañan los negocios o acuerdos jurídico-contractuales.

Discusión/Conclusiones/Contribuciones: su contribución está en comparar las diferentes ediciones del libro e identificar cambios en los discursos de los autores a través del tiempo, que evidencien rupturas y transformaciones sutiles de acontecimientos que permitan entender el significado de ética biomédica y explorar otras visiones de justicia en bioética.
The impact of organizational commitment on rural teachers’ retention: a moderated mediation study
Authors: Wang Zhihao , Zhen Ying , Yu Qianrui
Published: October 2024

The study aims to reveal the mechanisms by which organizational commitment influences the retention of rural teachers and how environmental fit and condition support modulate this relationship. It specifically examined the mediating role of environmental fit and the moderating role of supportive conditions in their relationship. A survey was conducted among 4,746 rural teachers across ten regions in Heilongjiang Province. The findings indicate: (1) There is a significant positive correlation between organizational commitment and the willingness of rural teachers to stay; (2) Environmental fit acts as a mediator in the relationship between organizational commitment and the retention intention of rural teachers; (3) Supportive conditions not only moderate the direct prediction of organizational commitment on the retention of rural teachers but also the predictive effect of organizational commitment on environmental fit. Therefore, to more effectively retain rural teachers, the following effective measures can be taken: optimize the rural educational environment to enhance teachers’ organizational commitment; refine recruitment and training systems to improve the fit of rural teachers with the rural environment; establish a monitoring system for the retention of rural teachers to enhance local educational supervision and accountability mechanisms.

Supervisors and central banks are trying to support the develop- ment of new technologies in the sector by reducing regulatory uncertainty and support programs aimed at FinTech (Financial Technologies) companies. The purpose of the study is to analyse existing regulations and regulators’ initiatives on new technologies in the banking sector. The author seeks to answer the research question of whether the introduced regulations support or limit the digital transformation of the banking sector in Poland. An im- portant aspect in the sector is customer security, so regulations should focus on protecting the banking customer and ensuring the stability of the sector. They are analysed by regulators so that the relevant regulations enable the introduction of innovative yet safe solutions. The author points out possible synergies resulting from cooperation between banks and FinTech companies. In conclusion, dialogue between banking sector institutions, regulators, central banks and banks leads to the creation of an environment that allows the introduction of innovative solutions while maintaining customer protection and banking sector stability.
Lannea microcarpa Leaves Extract as Corrosion Inhibitor for Aluminium Metal in Acid Medium
Authors: Umar Umaru , Muhammad Ayuba Abdullahi
Published: October 2024

Techniques for weight loss, electrochemistry, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) were used to investigate the inhibitory impact of Lannea microcarpa leaves extract. The weight loss data showed that the plant extract's ability to suppress corrosion increased with higher concentrations and decreased with higher temperatures and HCl acid concentrations. According to the electrochemical data, the plant extract uses a mixed type mechanism to limit both cathodic and anodic reaction rates. Calculated activation energies were found to be higher in inhibited systems than in uninhibited systems, indicating physisorption, while negative values of ∆G point to a process that is both possible and spontaneous. The inhibitory mechanism was demonstrated by FTIR spectra to be an adsorption process through the functional groups present in the phytochemicals of the plant extract onto the surface of Al metal. SEM surface morphology study demonstrated the protection that the extract provided on the metal surface. Compared to other isotherm models that were examined, the adsorption data were found to be more reliable and suited the Langmuir isotherm well.
Adsorption of ethylene and 1-methylcyclopropene (1-MCP) on Al-doped graphene structure: A DFT study for gas sensing application
Authors: Aydın Fatma , Sel Kıvanç
Published: October 2024

Ethylene is the ripening hormone of fruits and vegetables. 1-Methylcyclopropene (1-MCP) is used as the inhibitor of the ethylene actions for extending the postharvest shelf life of the plants. To control the ripening and extending the shelf life of the plants, the adsorption characteristics of ethylene and 1-MCP on Al-doped graphene structure (AlG) were investigated as a gas sensing application by density functional theory (DFT) calculations. The geometric structures were optimized, HOMO and LUMO, energy gap, adsorption energies, the density of states (DOS), electrostatic potential (ESP) and the global reactivities were calculated for different distances between the adsorbed ethylene or 1-MCP and the adsorbent AlG. Chemisorption and physisorption interactions were analyzed. For the chemisorption process of ethylene and 1-MCP on AlG, the adsorption energies were 19.34 kJ/mol and 56.53 kJ/mol, respectively. Whereas for the physisorption process, the adsorption energies of ethylene and 1-MCP were -60.16 kJ/mol and -7.32 kJ/mol, respectively. As a result, it was presented that the AlG structure has sufficient characteristics to be a good adsorbent and a gas sensor of ethylene and 1-MCP.

The study of the reaction of potato varieties, especially new ones, to the use of a complex of agrotechnical techniques, including foliar top dressing with water-soluble fertilizers, is an urgent task. For this purpose, 4 potato varieties of different ripeness groups (Red Scarlett, Nevsky, Golubizna, Grand) were studied in two regions of Russia using agrochemicals Agrovin Micro. Methods. The article presents experimental data on the study of biometric indicators, yield and quality of potatoes for non-root top dressing in conditions of leached chernozem and sod-podzolic sandy loam soils of the Central region of Russia. The objects of research were potato varieties of various ripeness groups. Foliar fertilization of plants with agrochemicals Agrovin Micro was carried out in the phases of germination, budding and 20 days after the last treatment in two consumption rates – 1.0 and 2.0 l / ha. Control – without processing (K) with background N90Р90К135.Results. On average, over the years of research, the best options for all varieties turned out to be options with the use of additional leaf treatment with an agrochemical at a maximum dose of 2 liters /ha. Due to three-fold foliar top dressing for the critical phases of potato plant growth, the greatest yield increases and maximum values of dry matter and starch content to the mineral background were obtained. In the conditions of the Tambov region, the increase in yield, depending on the variety, ranged from 24.2 to 59.3% or 6.0-10.5 /ha and in the conditions of the Moscow region – 3.3-28.9% or 1.2-7.1 t/ha. The most suitable for processing into fried potato products from the studied varieties turned out to be Red Scarlett and Grand. All other things being equal, the color index of crispy potatoes and fries on these varieties was higher than the Nevsky variety by 1.0-1.5 points.

W 1970 roku do publicznej obrony pracy doktorskiej przystąpiła Hanna Tadeusiewicz, obecnie już Profesor. Od tego wydarzenia minęło 50 lat. Monografia została opracowana z myślą o dostojnej Jubilatce, która poprzez swoją osobowość, pracowitość, systematyczność oraz liczne prace naukowe i organizacyjne w bardzo istotny, niezwykle pozytywny sposób wpłynęła na rozwój i kształt polskiej nauki o książce i bibliotece. Bibliologia i informatologia, dyscyplina funkcjonująca pod tą nazwą w obszarze nauk humanistycznych w latach 2011–2018, po reformie została włączona do nauk społecznych, tworząc wspólny obszar badawczy z szeroko pojętymi naukami o komunikacji społecznej i mediach. Naukowcy zajmujący się przedmiotami badań przynależącymi do bibliologii i informatologii wciąż jednak piszą teksty z pogranicza nauk humanistycznych i społecznych, koncentrując się na mediach (do których należy zaliczyć też książkę i bibliotekę), komunikacji społecznej, ale także na kulturze i historii, czasem na literaturze i języku. W publikacji zawarto teksty o charakterze interdyscyplinarnym, a wśród autorów znaleźli się bibliolodzy, informatolodzy, literaturoznawcy, historycy, językoznawcy i kulturoznawcy. Z pewnością zebrane w tomie artykuły okażą się wartościową lekturą dla badaczy i pasjonatów nauk humanistyczno-społecznych. Publikacja adresowana jest przede wszystkim do środowiska naukowego, ale również do studentów, bibliotekarzy i nauczycieli.
Szkoła – przestrzeń kultury książki. Stan badań bibliologicznych
Authors: Socha Irena
Published: October 2024

W nauce o książce badano, w różnych kontekstach historycznych i kulturowych, szkolne „obiekty bibliologiczne”, takie zwłaszcza, jak: biblioteka i inne księgozbiory tworzone na potrzeby procesu dydaktycznego; programy oraz realizacje dydaktyczne przeznaczone nauce czytania i nauce lektury; różnorodne świadectwa uczniowskiej i nauczycielskiej lektury, zarówno wspólnotowej, jak i indywidualnej. Odwołując się do reprezentatywnych przykładów prac badawczych z zakresu polskiej bibliologii historycznej i stosowanej opublikowanych w ciągu ostatniego trzydziestolecia, dotyczących kultury książki szkolnej od średniowiecza po koniec lat 50. XX wieku, określono główne koncepcje i kierunki badawcze. Zarazem ukazano w tym zakresie „pola styczne” badań bibliologicznych z badaniami nauk humanistycznych i społecznych, zwłaszcza historii oświaty i wychowania. Zwrócono uwagę na te kategorie stosowane w teorii bibliologii, które są przydatne, a nawet niezbędne dla badań historycznooświatowych. Zgromadzone przykłady przekonują, że perspektywa obserwacji wyraźnie przesuwała się, nie tylko w nauce o książce, z obiektów „klasycznych”, takich jak biblioteki, księgozbiory, instytucje książki oraz edytorskie egzemplarze, na repertuary – kanony lektur, w celu odczytywania ich kulturowych znaczeń i funkcji. Zasoby książki szkolnej badane były nie tylko ze względu na cechy formalne – edytorskie i piśmiennicze, ale przede wszystkim jako sui generis projekty kulturowe – przekazujące określony model wiedzy i kompetencji oraz system wartości.
Historia bibliotek publicznych dla dzieci (do 1914 roku)
Authors: Walczak-Niewiadomska Agata
Published: October 2024

Przez wiele lat bibliotekarstwo i bibliotekarze dziecięcy traktowani byli przez historyków i współczesnych sobie badaczy jako obszar niewymagający uwagi, a wręcz ignorowany i pomijany w przepastnych kompendiach wiedzy na temat bibliotekarstwa publicznego. Materiały w języku polskim, upowszechniające wiedzę na temat początków bibliotekarstwa dziecięcego na świecie, pojawiły się po II wojnie światowej w literaturze fachowej, jednak najczęściej były to publikacje stanowiące raczej przyczynki, rzadko traktowały temat kompleksowo. Tymczasem kierunki i sposoby rozwoju usług dla tej grupy czytelników stanowią ciekawy przykład przenoszenia tej idei i wdrażania jej na terenie państw całego świata. Celem artykułu będzie uzupełnienie stanu wiedzy w polskiej literaturze przedmiotu na temat początków wyodrębniania usług bibliotecznych dla dzieci i kształtowania tej gałęzi bibliotekarstwa publicznego. Pod uwagę zostaną wzięte kraje pionierskie (Stany Zjednoczone i Wielka Brytania), a także państwa, które do 1914 roku, dzięki inicjatywom podejmowanym przez czołowych propagatorów tej idei, przeniosły na swój teren rozwiązania zarówno merytoryczne, jak i architektoniczne (m.in. Belgia i niektóre kraje Skandynawii). Prezentowane w artykule zagadnienia opracowane zostały za pomocą metody krytycznej analizy przedmiotu, na bazie materiałów opublikowanych głównie za granicą. Dla rozwoju bibliotekarstwa dziecięcego w Stanach Zjednoczonych i krajach Starego Kontynentu w XIX i początkach XX wieku niepoślednie znaczenie miały zarówno stabilnie postępujące polepszanie warunków bytowych klasy średniej, jak i działalność organizacji wyznających wartości feministyczne, których celem była poprawa poziomu życia i edukacji kobiet. Źródła historyczne wielokrotnie wskazują na powtarzający się schemat polegający na edukacji przedstawicieli poszczególnych krajów w Stanach Zjednoczonych, a następnie przenoszeniu idei na grunt lokalny. W ten sposób krystalizowała się koncepcja bibliotekarstwa dziecięcego w większości krajów europejskich na przełomie XIX i XX wieku, a także w pozostałych częściach świata w późniejszych latach.
Obraz kulturalny Łodzi na łamach miesięcznika społeczno-literackiego „Wymiary” (1938–1939)

W końcu lat 30. XX wieku w intensywnie rozwijającym się „polskim Manchesterze” powstało Towarzystwo Artystyczno-Literackie, które powołało do życia, wydawany od kwietnia 1938 do czerwca 1939 roku, miesięcznik „Wymiary”. Pismo skupiające twórców o poglądach lewicowych i sympatyzujących z obozem Józefa Piłsudskiego propagowało model powszechnego dostępu do dóbr kultury oraz idee regionalizmu. Jako organ prasowy Towarzystwa periodyk wspierał także oficjalne (urzędowe) koncepcje rozwoju kulturalnego „złego miasta” oraz wskazywał na możliwości zmiany jego negatywnego wizerunku. Materiał opublikowany w 12 numerach pozwala na odtworzenie realiów życia kulturalnego Łodzi w drugiej dekadzie dwudziestolecia międzywojennego oraz umożliwia rekonstrukcję prokulturalnych działań władz miasta oraz środowiska literackiego. W artykule zaprezentowano działalność najważniejszych instytucji kultury i mediów. Omówione zostały także przedsięwzięcia towarzystw naukowych i instytucji oświatowych oraz projekty urbanistycznego rozwoju Łodzi.
