Authors: Ríos-Marín Alexandra , Sánchez Castelló María , Navas Marisol , Vázquez-Flores Erika , Rojas Antonio J.
Published: January 2025

The aim of this study was to analyze the perceptions and acculturation preferences of teachers toward young Moroccans and Romanians using quantitative and qualitative methodology. The quantitative study involved 181 teachers from Spanish public schools (56% female) who evaluated young Moroccans (N = 101) and Romanians (N = 80). In the qualitative study, focus groups and interviews were conducted with 29 teachers who gave their opinions about young Moroccans (17 teachers) and Romanians (12 teachers). In the quantitative study, it is perceived that young Moroccans adopt fewer Spanish customs (vs. Romanians), and Romanians maintain less their culture of origin (vs. Moroccans) and adopt more Spanish customs. Teachers prefer Moroccans to maintain less their own culture (vs. Romanians). The qualitative study shows a tendency towards intergroup homogenization, although with differences. Among young Moroccans, gender differences are perceived (girls adopt more Spanish culture), while young Romanians maintain less their customs (preferring that they maintain more) and adopt more Spanish customs (vs. Moroccans). Teachers highlight the importance of socioeconomic inequalities between Moroccans and Spaniards (vs. cultural differences), and the assimilation of young Romanians, perceived as similar to Spaniards.

Rola zmysłów i ich rozwój w zabawie dziecka w wieku przedszkolnym
Authors: Miłek Katarzyna , Wiśniecka Malwina
Published: January 2025

Tekst podkreśla znaczenie wczesnej stymulacji sensorycznej w rozwoju dziecka, szczególnie w okresie dzieciństwa, kiedy zmysły są wyjątkowo wrażliwe na bodźce. Metoda Montessori, poprzez manipulowanie materiałami, dotyk, obrysowywanie czyćwiczenia w grupie, wspiera rozwój poznawczy, emocjonalny i społeczny dziecka. Integracja Sensoryczna (IS) jest skuteczną metodą terapii dla dzieci z trudnościami w przetwarzaniu bodźców, jednak brak wystarczającej liczby specjalistów w tym zakresie stanowi problem. Pedagodzy mają więc moralny obowiązek wspierać dzieci, które intuicyjnie poszukują sposobów stymulacji sensorycznej, pomagając im w integracji sensorycznej i wspierając ich rozwój.

Published: January 2025

Enantioselective catalysis is one of the most prominent strategies in organic synthesis to access chiral bioactive compounds and advanced organic materials. Particularly the development of chiral ligands has significantly advanced the efficiency and selectivity of transition metal-catalyzed enantioselective transformations. Over recent decades, numerous chiral ligand classes with distinct geometrical and electronic properties were established. Despite these advances, the demand for novel, tunable, and highly effective chiral ligands persist, driven by the need for structurally diverse chiral molecules and the pursuit of greener, more sustainable catalytic processes. Herein, we introduce a novel class of chiral oxazoline ureas and demonstrate their potential as k2-N,O-preligands in enantioselective transition metal catalysis. The chiral oxazoline urea ligands were featurized and compared with amide and enol derivatives using the physical organic descriptors. A multivariate linear regression model was constructed to quantitatively describe the effect of the quinoline fragment from the substrate and the ligand on enantioselectivity. Moreover, the model was effectively applied to atropo-enantioselective cobaltaelectro-catalyzed C–H annulations of 1-alkynyl indoles.

Enantioselective electrocatalyzed C−H activations have emerged as a transformative platform for the assembly of value-added chiral organic molecules. Despite the recent progress, the construction of multiple C(sp3)-stereogenic centers via a C(sp3)−C(sp3) bond formation has thus far proven elusive. In contrast, we herein, report an annulative C−H activation strategy, generating chiral Fsp3-rich molecules with high levels of diastereo-and enantio-selectivity. We have employed novel κ2-N,O-oxazoline preligands for the first time in enantioselective cobalt(III)-catalyzed C−H activation reactions. Using DFT-derived descriptors and regression statistical modeling, we performed a parameterization study on the modularity of chiral κ2-N,O-oxazoline preligands. The study resulted in a model describing ligands' selectivity characterized by key steric, electronic, and interaction behaviors.
Vapor Phase Installation of CpCo(CO)2 in MOF-808

Published: January 2025

Metal-organic frameworks (MOFs) including MOF-808 present an opportunity for vapor phase installation of reactive centers that may serve as uniform sites for precision catalysis. The mechanism of cobalt installation in MOF-808 through atomic layer deposition (ALD) upon CpCo(CO)2 exposure is investigated through in situ FTIR spectroscopy complemented by density functional theory modeling. The role of subsequent H2O exposure in the hydrolysis of carbonyl and cyclopentadienyl ligands to complete the installation is also investigated. In situ FTIR study reveals that upon exposure of CpCo(CO)2 to MOF-808 at 115 °C, a long-lived, stable intermediate is formed that presents carbonyl stretching vibrations similar to the undissociated precursor that are attributed to chemisorbed carbonyl complexes. In MOF-808, the cobalt precursor is initially absorbed near the BTC linker, revealing the importance of non-covalent interactions in the installation process. DFT suggests that subsequent H2O exposure promotes carbonyl elimination but leaves a cyclopentadienyl-capped cobalt that is more stable than the complete hydrolysis product. The calculations are consistent with cobalt installation in MOF-808 using CpCo(CO)2 and H2O at 115 °C and further consistent with a lack of cobalt oxide ALD thin film deposition on planar supports.

A profound mechanistic understanding of material formation is imperative for developing tailored syntheses. However, insights into solution-based oxide syntheses remain limited to selected systems. Hydrothermal MMoO4 (M = Fe, Ni, Co) formation is governed by the initial pH, implying the involvement of pH-dependent polyoxomolybdate cluster chemistry. Nevertheless, the exact role of clusters in forming molybdates remains poorly understood. Here, we use in situ X-ray total scattering to follow the hydrothermal syntheses of MMoO4 and related hydrates at various pH values, using Co-based reaction mixtures as our primary model system. Focussing on the structural investigation of non-crystalline species, we find no heteropolyoxometalates under the probed conditions. This contrasts our results from reported MWO4 formation pathways and thereby reiterates the element-specific nature of nucleation chemistry. Moreover, we observe pH- and temperature-dependent formation of bimetallic phases that cannot be explained by polyoxomolybdate chemistry alone. Our results therefore point towards a product-directing role of the 3d metal complex speciation under hydrothermal conditions, emphasising the mechanistic complexity of ternary oxide formation.
Formulations and evaluations of repaglinide microspheres by ionotropic gelation technique
Authors: Archana B , Vaishnavi Balla , Sindhu Kannayyagari , Goud Keesari Meena , Poojitha D. Sai
Published: January 2025

The current study aimed to formulate and evaluate Repaglinide microspheres utilizing the ionotropic gelation process, with sodium alginate, HPMC, and Carbopol as polymers and Cacl2 as a cross-linking agent. Because of its high biocompatibility and lack of toxicity, sodium alginate is a biodegradable natural polymer with considerable promise for therapeutic uses. Repaglinide microspheres offer desirable qualities. The ionotropic gelation approach allows for high medication integration in microspheres without harmful agents that have adverse side effects. The microspheres are tested for percentage yield, entrapment efficiency, micromimetic properties, in-vitro drug release, etc. Extensive in-vitro testing revealed that more than 102% of the medication is released after 11-12 hours; however, in this formulation, drug release is maintained for up to 12 hours. The percentage entrapment efficiency is 102%. The microspheres had a percentage yield of 96%. Using essential equipment, ionotropic gelation can also be carried out under relatively mild situations. Managing numerous manufacturing parameters is critical in producing microspheres with superior sphericity, high yield, and exceptional drug encapsulation.
Communicative Practices in the Conditions of Mass Media Space Hybridization: Interdisciplinary Interference as the Epistemological Requirement
Authors: Susska Olga
Published: January 2025

The article is devoted to consideration of how modern information technologies have changed the nature of communicative relations, significantly expanded the possibilities and scope of communicative interaction in the information space. By subordinating their goals and results to these possibilities, in particular, the interpretive possibilities of thinking, it gave birth to a new type of information exchange and communicative relationships, which is associated with the entry into the information society. The transfer of a significant part of information flows to the worldwide Internet makes it difficult to control them by certain social institutions. The hybridization of the media space appears as a problem that is increasingly difficult to investigate within the framework of only one scientific discipline, or even field. Thus, interdisciplinary interference appears as an epistemological requirement of media space research, which can be implemented only if clear principles of an interdisciplinary approach are implemented in the field of studying communicative practices, the use of terminology, and the use of effective methodology, which allows for a real synthesis of cognitive tools. A separate issue is the study of new phenomena of the modern media space, in particular, the contamination of the subjectivity of information exchange in Internet networks and the transformation of traditional mass media audiences into interpretive communities. The emergence of new actors who impersonate themselves in Internet networks and are actually "agents of change" requires sociologists to focus their attention on these new subjects. Large-scale quantitative studies, which were relevant to the mass audiences of traditional media at the end of the last century, no longer give the expected result. The conceptual prerequisites for activating the appeal to the possibilities of interdisciplinarity are the transformations of modern communicative processes, which cause not only an increase in attention to the manifestations of subjectivity on the part of both the media communicator and the recipient, but also the importance of applying an interdisciplinary approach to the multidimensionality of transformations in the modern hybridized media space.
Education System Actors on the Transformation of the Social Order of Schooling in the Context of Russian Aggression
Authors: Sokurianska Liudmyla , Sopilnyak Dmitriy
Published: January 2025

The article emphasises that Russia's aggression against Ukraine has significantly changed the social order of Ukrainian society as a whole, all its substructures, including the education system, in particular the school system. It is noted that, having analysed the definitions of the concept of "social order" presented in the sociological discourse, in particular, the definitions of this concept formulated by such classics of sociology and modern sociologists as M. Weber, R. Park, C. Polanyi, J. Padiolo, Z. Bauman, D. North and others, the authors focused on the axiological approach to the interpretation of social order. The author's definition of the relevant concept is given, namely: social order is an interaction (communication) between the subjects of a certain social system based on internalised norms and values, which ensures its successful functioning. It is emphasised that changes in the external environment of a particular system can lead (and usually do lead) to changes in these systems themselves, in particular, to changes in their functions, which, in turn, actualises changes in the existing social order and the emergence of its new forms. It is argued that under the influence of the changes that have taken place in Ukrainian society since the beginning of the Russian aggression, the functions of such a social system as education and, accordingly, the social order inherent in it have undergone a significant transformation. It is noted that this conclusion is based on the results of the research project "School in Time of War" implemented by the Wergland European Centre (Norway, Oslo) within the framework of the Programme of Support to Educational Reforms in Ukraine (2021-2024) (with the participation of one of the authors of the article). It is emphasised that this study was carried out using qualitative methods such as individual in-depth and focused group interviews (FGI). A total of 30 in-depth and 3 FGIs were conducted with Ukrainian teachers, school principals and high school students representing secondary education institutions located both in regions close to active hostilities (in cities such as Kharkiv, Mariupol, Irpin, Bucha, etc.) and in relatively safer cities (Lviv, Lutsk, Ivano-Frankivsk, Odesa). The data obtained in the framework of this study demonstrate changes in the role and functions of the national school education system in the context of war, in particular, the actualisation of its role as a space of security, organisation of volunteer activities and psychological support. It is concluded that the transformation of the content and nature of interaction between the main actors of the education system (school administration, teachers, students and their parents) has led to the emergence of a new social order within this system, transformed the previously existing hierarchical relations between educational actors into horizontal ones, and formed a new model of social order, namely, the school as a "big family".

KOBİ'lerin Sermaye Yapısı Kararlarının Ardındaki Güdüler: Halka Kapalı İmalatçı KOBİ’ler Üzerinde Bir Uygulama
Authors: Yılmaz Salih Rıdvan , Uçkun Nurullah
Published: January 2025

Küçük ve Orta Büyüklükteki İşletmeler (KOBİ'ler) yatırım finansmanına ulaşım konusunda çeşitli sorunlar yaşamaktadırlar. Finansal açık olarak bilinen bu problem kaynak kullanımı sırasında KOBİ’lerin aldıkları kararları etkilemektedir. Bu sermaye aksaklığının etkilerini ve sonuçlarını ölçmek amacıyla Eskişehir Organize Sanayi Bölgesinde faaliyet gösteren halka kapalı 112 adet imalatçı KOBİ ile anket çalışması gerçekleştirilmiştir. Elde edilen bulgularda işletmelerin büyük bir kısmının finansmanda iç kaynak kullandığını, mikro ölçek özelinde ise işletmelerin daha büyük bir kısmının finansmanda ilk olarak dış kaynağı seçtiği görülmüştür. Borç hedefi ve kaynak kullanımı tercihlerine bakıldığında, mikro ölçekli işletmelerin diğer ölçeklerdeki işletmeler ile kıyaslandığında dengeleme teorisine oransal olarak yakın davrandıkları sonucuna varılırken, orta ölçekli işletmelerin yüzdesel olarak hiyerarşi teorisine daha yakın hareket ettiği görülmüştür. KOBİ’ler yüksek borçlanma seviyelerinin bağımsız hareket etmeyi zorlaştırmasını da önemli bir sorun olarak değerlendirmektedir.

Published: January 2025

Bu çalışma, Türkiye'nin Antalya ilinin önde gelen destinasyonlarından biri olan Alanya'daki yoğun turizm gelişimine yönelik yerel halkın algılarını değerlendirmeyi amaçlamaktadır. Alanya, Türkiye'ye gelen yabancı turistlerin %15'ini ve Antalya'ya gelenlerin ise yaklaşık 1/3’ünü ağırlamaktadır. Bu durum Alanya'yı kitle turizminin etkilerini incelemek adına önemli bir örneklem haline getirmektedir. Araştırma kapsamında 450 anket formu toplanmış ve veriler SPSS paket programına aktarılarak analiz edilmiştir. Elde edilen tatmin edici bulgular sonucunda yapısal model AMOS programı kullanılarak test edilmiştir. Çalışma, yoğun turizmin yaşam yeri ve yaşam kalitesi üzerindeki etkilerine dayanarak yerel halkın turistlere yönelik tutumları ve turizmin gelişimine ilişkin genel algılarına yönelik tutumlarını araştırmaktadır. Elde edilen bulgular neticesinde, yoğun turizm faaliyetlerinin yerel halkın yaşam yeri ve yaşam kalitesi üzerinde olumsuz etkilerinin olduğu tespit edilmiş ve bu doğrultuda bölge sakinlerinin turistlere yönelik olumsuz tutumlar sergiledikleri belirlenmiştir. Ancak, yerel halkın yoğun turizm faaliyetlerinin yaşam kalitesi üzerindeki etkilerine bağlı olarak turizm gelişimine yönelik olumlu tutum içerisinde oldukları sonucuna ulaşılmıştır. Ayrıca, yerel halkın turistlere karşı sergiledikleri tutumun turizm gelişimine yönelik sergiledikleri genel tutuma olumsuz yönde etki ettiği de tespit edilmiştir. Araştırma sonucunda ulaşılan bulgular ışığında turizm sektörü yöneticilerine, politika yapıcılarına ve diğer turizm paydaşlarına yönelik çeşitli öneriler sunulmuştur.
