Reinforcement of graphene nanoplatelets on water uptake and thermomechanical behaviour of epoxy adhesive subjected to water ageing conditions
Authors: Jia Zhemin , Ye Haoyan , Liu Qian , Zhang Zhicheng , Grima Joseph N.
Published: December 2024

Adhesive joints are frequently utilized due to their lightweight nature and minimal damage to the substrates. However, their application is constrained by a lack of reliable performance under moist conditions. This study assesses the impact of incorporating varying concentrations (0.25–0.75 wt%) of graphene nanoplatelets (GNPs) on moisture uptake, dynamic thermal properties, and tensile behaviour of engineered epoxy adhesives when subjected to water for periods of up to 8 weeks. The objective of this study is to ascertain the optimal concentration from the standpoint of degradation in the thermomechanical performance of the epoxy resulting from water ageing. The addition of GNP results in a 45% reduction in the diffusion coefficient of the 0.25 wt% GNP-modified epoxy relative to the unmodified epoxy. The reduced absorption of water by the GNP-reinforced adhesive results in diminished thermomechanical degradation, particularly during the initial immersion period (less than 14 days). The loss modulus exhibits an increase of up to 21% in comparison with the unmodified epoxy. The reduction in tensile strength of the modified epoxy is 53% less than that of the unmodified epoxy following 14 days of water ageing. Under the same water ageing conditions for 14 days, the epoxy modified with 0.25 wt% GNP exhibited a 75% increase in tensile strength compared to the unmodified epoxy. This work may facilitate the GNP application in epoxy adhesive joints, thereby enhancing their durability under high humidity conditions.

Published: December 2024

Carbon nanotubes (CNTs) have received extensive attention due to their exceptional properties and wide range of applications. However, the agglomeration of CNTs in aqueous solutions and organic solvents significantly limits their large-scale application. In this study, the microscopic morphology and dispersion stability of the CNT suspensions were analyzed, and the most suitable surfactant in this study was selected. The preparation parameters of the CNT suspensions were optimized, and uniaxial compression tests were conducted on carbon nanotube concrete (CNTC) prepared using the optimized parameters. Scanning electron microscope analysis was used to investigate the improvement in the microstructure of the concrete by CNTs. Transmission electron microscope micrographs of the polyvinyl pyrrolidone (PVP)-CNT suspensions exhibited a uniformly distributed CNT cross-linked network. The absorbance reduction ratio of PVP-CNT suspensions after standing for 90 days was 13.75 and 22.41%, respectively. The absorbance reduction ratio of the suspensions first increased and then decreased with increasing dispersant ratio and ultrasonic dispersion time and increased with increasing ultrasonic power ratio. Compared with that of plain concrete, the uniaxial compressive strength of CNTC significantly improved, with a maximum increase of 18.15% when the content was 0.10%, and the failure mode exhibited typical shear failure characteristics. The optimized preparation parameters for the CNT suspensions were a PVP-to-multiwalled carbon nanotube mass ratio of 4:1, an ultrasonic dispersion time of 20 min, and an ultrasonic power of 60%. These optimized parameters are ideal choices for preparing CNT cement-based composite suspensions.
Organisation und Kreativität. Zur Idee des schöpferischen Bürokraten
Authors: Wolf Burkhardt
Published: December 2024

Immer weniger scheinen die Verwaltungen der Gegenwart durch rigide Hierarchien und routinierte Abläufe gekennzeichnet, dafür zusehends durch lose Kopplungen und flexible Aufgaben. In ihren Strukturen und Prozessen herrscht konstitutive Unsicherheit und Kontingenz. Und diese beanspruchen Organisationen nicht bloß zu bewältigen, sondern vielmehr auszunutzen. Denn einerseits scheinen Problemlösungen und Entscheidungsfindungen unter den Vorzeichen des Zufalls und Nicht-Wissens zu laufend neuen Zwecksetzungen zu führen, zu einer gleichsam kreativen Organisation der Organisation. Andererseits lässt sich die Ressource der Kreativität, nach dem alten Konzept und Muster des Genies und schöpferischen Menschen, leicht persönlich zurechnen – und damit als Auswahl- und Bewertungskriterium der Human Resources operationalisieren. Mehr und mehr richten sich gegenwärtige Verwaltungen derart an para-ästhetischen Kategorien aus. Wechselbeziehungen wie die zwischen Zweckfreiheit und Zweckgebundenheit, zwischen Kontingenz und Regel oder zwischen Informalität und Formalität nähern sie augenscheinlich ihrem vormals Anderen an: der Kunst und den Kreativen.
Über Schatten und Elefanten. Geheimnissoziologische Überlegungen zu Organisationen
Authors: Firkus Dennis
Published: December 2024

Geheimnisse und Geheimhaltungen sind nicht nur in Interaktionen, sondern auch für den Bestand von Organisationen von Relevanz. Die Studienlage spiegelt diesen Umstand kaum wider: In der Organisationsforschung bleiben Geheimnisse Gegenstand allenfalls impliziter, aber nur selten expliziter Auseinandersetzungen. Der vorliegende Beitrag knüpft an dieses Desiderat an. Hierfür wird ein soziologischer Geheimnisbegriff skizziert, der an ein primär systemtheoretisches Organisationsverständnis angeschlossen wird. Organisationen implementieren, so die These, verschiedene Strategien oder Barrieren, um sensible Wissensbestände zurückzuhalten. Anhand einer Neuinterpretation zweier von der soziologischen Forschung bereits untersuchter Fälle, der Korruptionsaffäre der Siemens AG sowie der Challenger-Katastrophe, werden Potenziale einer geheimnissoziologisch sensibilisierten Forschung in der Organisationstheorie herausgearbeitet. Während für beide Beispiele eine gewollte und zweckspezifische Enthüllung einiger Informationen beobachtbar ist, ist die weitergehende Verhüllung anderer Wissensbestände im Fall von Siemens in einer informalen Schattenstruktur angesiedelt. Vorgänge innerhalb der NASA werden als Konstruktion und Aufrechterhaltung eines offenen Geheimnisses reinterpretiert.

Authors: Ortega Ruipérez Beatriz , Correa Gorospe José Miguel , Aberasturi-Apraiz Estibaliz
Published: December 2024

El objetivo es conocer la influencia de las trayectorias de aprendizaje de los futuros docentes de infantil y primaria en sus perspectivas de mejora social, conociendo si existen perfiles diferenciados por etapa. Se elige un método cualitativo para que reflexionen sobre sus trayectorias de aprendizaje contadas con cartografías y el visionado de películas que muestran a profesores que trabajan para la equidad, y la posterior puesta en común y reflexión grupal que permita responder al objetivo. Los resultados muestran que las experiencias previas influyen en la vocación docente, especialmente antiguos profesores y el contacto previo con niños y niñas, con diferencias entre infantil y primaria, según si el contacto previo ha sido por cuidado de familiares pequeños o como profesores particulares o monitores, respectivamente. Respecto a la equidad, destacan el formar buenos ciudadanos, concienciando sobre una sociedad diversa en infantil, y abordando situaciones de desigualdad con una educación personalizada en primaria. Así, se concluye que las experiencias vividas en sus trayectorias de aprendizaje influyen en la percepción de mejora social que pueden conseguir desde estas etapas. Por último, se propone un perfil común de los futuros docentes de infantil y primaria, y también un perfil específico para cada etapa
Uso de vísceras bovinas en alimentación del pez guppy (Poecilia reticulata) como alternativa económicamente viable
Authors: Sanabria-Astúa Sofía , Chacón-Villalobos Alejandro , Herrera-Muñoz Juan Ignacio
Published: December 2024

El objetivo del presente estudio fue valorar la inclusión de vísceras bovinas en la dieta del guppy (Poecilia reticulata) como una alternativa económicamente viable y atractiva, al evaluar el efecto en el crecimiento y desempeño reproductivo del pez incluyendo corazón y riñón bovino deshidratado en las raciones alimentarias. La investigación se realizó durante 60 días en el Módulo Acuícola de la Estación Experimental Alfredo Volio Mata (EEAVM). Se utilizaron 320 animales de 30 ± 2 días de edad. Después de un periodo de 15 días de aclimatación, se distribuyó aleatoriamente un total de 20 individuos por pecera. Se utilizaron cuatro tratamientos experimentales: Control, que incluyó únicamente alimento balanceado (AB) comercial para pez guppy; Tratamiento 1 (T1), que se compuso únicamente de AB comercial para tilapia-fase de inicio; Tratamiento 2 (T2), que fue formulado con 52,5% de AB comercial para tilapia-fase de inicio y 47,5% de corazón bovino deshidratado; y Tratamiento 3 (T3), que fue integrado por 45,3% AB comercial para tilapia-fase de inicio y 54,7% de riñón bovino deshidratado. Se empleó anestesia general en los animales cada 15 días con el fin de tomar mediciones de ganancia de peso total (GPT), tasa específica de crecimiento (SGR), coeficiente térmico de crecimiento (CTC), conversión alimenticia (FCR) y factor de condición de Fulton (K). Se encontraron diferencias significativas (p < 0.05) en ganancia de peso promedio general (GPg) y ganancia de peso promedio para las hembras (GPh) entre el T1 y el resto de tratamientos, sin diferencias entre estos últimos. No se observaron diferencias significativas para la variable de fecundidad entre tratamientos (p > 0.05). Sin embargo, se dio una tendencia (p = 0.091) de mayor cantidad de alevines nacidos en los tratamientos T2 y T3. El análisis económico mostró que el tratamiento Control posee el costo más elevado, seguido por T3, T2 y T1, respectivamente. Por esta razón se considera que el uso de vísceras bovinas, en combinación con alimentos comerciales, es una alternativa técnica y económicamente viable.

Use of cartographic data in crisis management
Authors: Mika Monika , Kotlarz Paweł , Kuros Karolina
Published: December 2024

The subject of the research in this paper was a review and identification of types of cartographic documentation used in crisis management in Poland. The analysis focused mainly on assessing the usefulness of cartographic data for visualising the scale of natural phenomena such as floods, landslides, droughts, wind, and others. The most important map that serves as a reference base for various types of industry-related works, especially derivative geodetic works, is the cadastral map stored in the resources of the Land and Building Register. In this study, the authors concentrate on the possibilities of using cartographic data, with a particular emphasis on cadastral maps, for crisis management purposes. The aim of this paper is to review and provide an expert assessment of the usefulness of cartographic data in emergency situations. The research shows that cartographic data are crucial for each of the mentioned hazards, especially the resources of the Land and Building Register, which allow the visualisation of the spatial and temporal scale of these hazards. The success of the measures taken to reduce the occurrence of floods or landslides, for instance, depends first and foremost on fast and seamless access to reliable and up-to-date information on the terrain. The cadastre is one of the publicly accessible registers providing this data, without which crisis management could not be fully effective. The study was conducted through an online survey using an interactive sheet, dedicated to experts (services dealing with different types of hazards).
Evaluation of heavy metals pollution in recent sediments of Zoubia Wadi, W-Skikda (NE of Algeria)
Authors: Boukoffa Mechati , Boucenna Fatih , Lamouri Bachir , Bouabsa Lakhdar
Published: December 2024

This study aims to evaluate the level of metallic pollution in the recent sediments of the Zoubia area (Ain Kechera) in north-east of Algeria. The method used for this assessment involves sediments sampling and the determination of heavy metal concentrations. The study estimated the level of metallic pollution in the sediments by calculating several pollution indexes, including the contamination factor (CF), the enrichment factor (FE), the geo-accumulation index (Igeo), the individual ecological risk index (), the potential ecological risk (RI) and statistical analysis of the data. The study monitored seven trace metals: cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), zinc (Zn) and copper (Cu). The results indicate an enrichment of Cd, Pb, Zn, and Cu in all samples. However, Ni, Co, and Cr levels are below those of the continental crust (background). The geo-accumulation index values for Co, Ni, and Cr are negative in all samples. On the other hand, positive geo-accumulation index values were observed for Cd, Pb, Zn, and some Cu samples (B1, B2, B3, and B4) with individual ecological risks of less than 40 for Cd, (94.48–119.21) for Zn, and (80.23–135.4) for Cu, respectively. This indicates low risk for Cd and high risk for Zn and Cu. The results indicate that Pb poses a significant ecological risk (537.4–842.05) and may have adverse effects on human health. The most significant pollutants, in order of increasing risk, are Pb, Cu, Zn, and Cd.
The environmental impact of dam construction in a wetland area. A case study Boukhroufa (El Taref) Algeria

Published: December 2024

This article presents an approach to the assessment of the environmental impact of a dam construction for agricultural use in the Boutheldja region. This region’s environment is rich in natural resources and forms a part of the El Kala National Park (P.N.E.K). It was designated a wetland of international importance under the Ramsar convention by UNESCO in 1983 and later declared a biosphere reserve in 1990. It is among the most significant aquatic areas in this region (contains about 40% of surface water resources). The physical characteristics of the watershed support the construction of the dam, although there could be a number of unfavorable effects: upstream – including soil erosion and reservoir sedimentation, reduced storage capacity, lower water quality and loss of productivity of flooded area; downstream – removal of silt from downstream flows, loss of fertilising functions, changes in water quality, changes in productivity, reduction in natural floods, loss of access to resources and ecological disturbance. Such processes will have an impact on an ecosystem so fragile. Although Boukhroufa dam provides significant benefits to the city, such as controlling stream regime, preventing floods, and supplying agricultural water from stored water, it also has significant negative effects on the surrounding watershed ecosystem.

Published: December 2024

Socialinis ugdymas ir saviugda yra neįmanomi be atitinkamo kultūrinio proceso. Šiuo metu Lietuvos kultūros politika yra reguliuojama dviem teisės aktais: „Lietuvos valstybės strategija 2050“ ir „Lietuvos kultūros politikos pagrindų“ įstatymu, o formuojama ir visuomenės iniciatyvomis. Deja, šie abu svarbūs dokumentai nestokoja spragų, o strategija pasižymi kultūros sampratos vartosenos daugiaprasmiškumu ir chaotiškumu. Lietuvoje tebėra gajus siauras, tačiau atgyvenęs kultūros prilyginimas menams ir paveldui. Tai atspindi tradiciją, kilusią iš aristokratijos poreikių. Jos vietą turėtų užimti pažangios kultūros, nukreiptos į bendros gerovės, teisingumo, saugumo, laisvių ir tam reikalingos tvarkos didinimą visuomenėje samprata.
Kultūros, intelektinio kapitalo ir inovacinės politikos sanglauda, kuriant gerovės valstybės realijas

Nuo sukviesto pirmojo Kultūros kongreso praėjo šimtmetis. Vis greičiau besikeičiantis pasaulis kiekvienai kartai kelia naujų uždavinių. Problema – mūsų mažai tautai išlikti globaliame pasaulyje savitu veidu. Gebėti būti kūrybingai, inovatyviais metodais ugdyti ateinančias kartas, valstybę, pagarbiai ir prasmingai kurti pasaulyje kultūros (mokslo, švietimo, meno), ekonomikos, socialinius ryšius. Brandinti intelektinį potencialą, kuris valstybės valdymo inovacinę politiką pasitelks formuluojamam tikslui – sukurti gerovės valstybę, Lietuvą. Per tris dešimtmečius pradėjo formuotis naujas požiūris net į geologinį laikotarpį, kurio pradžią mokslininkai fiksuoja nuo Antrojo pasaulinio karo pabaigos. XXI a. išryškėjo žmogaus ir dirbtinio intelekto santykių sudėtingas etapas. Pamatinis Homo Sapiens bruožas yra gebėjimas kurti. XXI a. humanoido pasirodymo pasaulyje laikas. Žmogui būdingas savybes turintis robotas Pepper (Japonija) netgi perpranta žmogaus emocijas. Elonas Muskas žengia dar toliau – kuria ryšius tarp žmogaus smegenų ir dirbtinio intelekto. Tai žavi kaip mokslo jėga ir baugina roboto galimybės veikti savarankiškai prieš žmonijai išgyventi svarbius moralinius principus. Valstybės privalo ugdyti vertybių pagrindą turinčius mokslininkus, kad jų kuriami produktai nekeltų visuomenei pavojų, pasaulio sunaikinimo grėsmių. Pedagogai pastebi, kad postmodernios kultūros kontekste ryškėja kultūros pliuralizmas ir globalizacijos procesai jau pakeitė asmens saviorganizacijos principus, griauna egzistavimo stabilumą, socialinio saugumo patirtis. Yra ir kitų problemų. Todėl svarbu jas įvardyti, įvertinti, pagrįsti piliečio (asmenybės) intelektinio kapitalo ir inovacinės politikos sanglaudos vystymo bazinės terpės – kultūros – svarbą.

"I won't bite": Generative AI, Robotics, and the Ethics of Loss in Black Mirror 201 "Be Right Back"
Authors: Fisher Jaimey
Published: December 2024

Since its premiere in 2011, Black Mirror has proven itself an important television series in its industrial impact and in its thematic ambitions: the show examines how we are to live with contemporary technology. One of its most celebrated episodes, "Be Right Back" (episode 201) considers how AI chatbots and robots can, and cannot, help people deal with personal tragedy. A key question for the show is how episodes like "Be Right Back" construct the ethical and moral dilemmas at the core of contemporary technologies. The essay examines how episodes invite viewers' interest and sympathy in familiar ways, namely, through focalization with key characters, but then rely on how viewer engagement with those characters can manipulate on-going moral and ethical dimensions. In this famous episode, those moral and ethical dimensions of character engagement are mapped onto the personal tragedy and the technological potential to ameliorate it for its main characters.

The article discusses the issues of carbon removal in a circulating vacuum unit. It is shown that in order to achieve an ultra-low carbon content (less than 0.002 %), it is necessary to take into account the wear of the lining of steel ladles. When replacing periclase-carbon products in the walls and bottom of the steel ladle with carbon-freeones, carbon intake into the melt can be significantly reduced. Additionally, rational technological parameters of steel processing in a circulating vacuum unit were determined.
Interaction of рarticles of different size classes in the separation flows
Authors: Barsky M.
Published: December 2024

At present, theoretical concepts of gravitational separation processes are mainly limited by the study of the interaction between a ﬂow and a solitary particle. Then the main conclusions of this analysis are applied to a mass process. However, this analysis is absolutely insuﬃcient, because some elementary phenomena such as the ingress of coarse particles into the ﬁne product output and vice versa cannot be interpreted from its standpoint. It is also impossible to predict the results of the classiﬁcation of a material with a speciﬁc granulometric composition on a speciﬁc apparatus on its basis. This article discusses o more complete model of the process. It is based on the behavior of a plurality of particles of diﬀerent sizes. This made it possible to determine the probalitity of particles of diﬀerent sizes in the separation ﬂows. This is how on additional parameter is obtained in the general process model.
Enhancing Grade XI Students' Learning Outcomes Through the Gamified Use of the Kahoot Application
Authors: Chophel Yonten
Published: December 2024

The purpose of this study was to establish whether the Kahoot application can serve as a gamification tool that would improve the academic achievement and engagement of students. A total sample of 64 Grade XI students was selected from Daga Higher Secondary School in Dagana.  This study employed a quasi-experimental design within the Action Research framework. A mixed-methods approach was used for data collection, with quantitative data collected through participant observations, pre-and post-tests, and surveys, and qualitative data gathered through semi-structured interviews. Quantitative analysis included means, standard deviations, and t-tests, whereas thematic analysis was used for qualitative data. The findings showed that there was a statistically significant difference in mean scores between the experimental and control groups at a medium to large effect size, using Cohen's d = 0.72. These findings show that the Kahoot application enhanced classroom participation and academic performance of students at a great scale, which might be an efficient pedagogical tool in high school education.
Improving Fifth-Grade Students’ Reading Comprehension of Literary Texts by Enhancing Their Academic Emotions
Authors: Ugyen Phuntsho
Published: December 2024

Teaching and learning English in Bhutan focuses on students' cognitive outcomes with minimal attention to their emotions and self-regulated learning abilities. Using an action research methodology, this study examined how fifth-grade students’ reading comprehension of literary texts can be enhanced by improving their academic emotions during reading. The study was conducted with 24 fifth-grade students at a primary school in central Bhutan. Students’ academic emotions during reading were measured using a modified version of the Achievement Emotions Questionnaire (AEQ). Pre-test and post-test questions for reading comprehension were administered, and eight observations were made simultaneously. The results of data analysis using t-test and descriptive statistics revealed a statistically significant difference between the mean scores of the pre-test test (4.14; SD = 2.26) and post-test (M=6.19; SD=1.44) at p<0.05, indicating an improvement in students’ reading comprehension. This was further confirmed by analysing the observation notes recorded by a critical friend during the pre-test and post-test. The results showed that students’ positive academic emotions enhanced students’ reading comprehension abilities. Based on the findings, implications were discussed, and recommendations were proposed for English teachers and students.
Voucher tokenisation using blockchain and smart contracts to support people in need
Authors: Harraway Tricia , Bekker James
Published: December 2024

In South Africa, many people are homeless or doing informal work for which they receive small amounts of cash from caring individuals. The world is moving towards cashless transactions, but devices are needed to support that move. Many people in need cannot afford such devices and usually receive cash, but fewer donors carry cash. Consequently, people in need receive less informal financial support. We propose a system that allows donors to give digital vouchers that can be redeemed at participating stores and institutions of care. This study aimed to investigate the use of blockchain technology in digital voucher management and to demonstrate the application of smart contracts to disintermediate the value transfer process specific to the donation process. A demonstrator was built to include a front end for the user to interact with and a back end containing the application logic, which was built on the Polygon blockchain, a second-layer solution for the Ethereum blockchain. The model included tokenising vouchers as non-fungible tokens, and the smart contracts governed their logic and the conditions to be met. The demonstrator was validated using smart contract and unit tests to evaluate the security and functionality. While the model was not implemented in reality, a fully functioning demonstrator was developed. The platform achieved the aim of disintermediating the voucher management process. A real-world implementation could help many in need to receive tokens for food, shelter and clothing from direct, individual donors.
Leer las persistencias de la escritura, una política de lectura desde el archivo
Authors: BERNABEI Verónica
Published: December 2024

Hay dos instancias que separan a la obra del archivo. Por un lado, la naturaleza de los documentos y por el otro el modo en el que tales documentos son ordenados y leídos. Acceder a un archivo es acceder a un aparato de lecturas ordenadoras, a un campo de pulsiones destructivas que delimitan sus bordes y sin las cuales no podría existir. En confrontación con ese orden, leer un archivo no es leer la obra ya que los documentos que lo componen manifiestan un estado en constante cambio, manifiestan el movimiento de la escritura con todos sus titubeos, retornos, claudicaciones, con todo su presente.
En este capítulo proponemos una lectura basada en lo que caracteriza al archivo y lo diferencia de una obra publicada: el espacio entre el texto inacabado y la potencialidad de la escritura. A partir de tal distinción, nos detendremos en una peculiaridad de la escritura de Juan José Saer que se revela en los cuadernos que integran el archivo y que pone en tensión los criterios de intervención que lo organizan. Se trata de lo que llamaremos “ritornelos” o persistencias de la escritura, es decir frases o imágenes que se repiten a lo largo de años, hasta encontrar un lugar definitivo. Invisibles en tanto no forman parte del material pre-redaccional de las obras publicadas y por lo tanto, difícilmente trazables en el archivo de la biblioteca de Princeton, su origen no se confunde con el texto, sino que es exterior, más antiguo y enigmático. Trabajar con estas persistencias y su dinámica de escritura presente es leer desde y con los archivos. Sobre esta imprecisión e inestabilidad abierta a las conexiones radica también nuestra concepción del archivo como política de lectura.

Üniversite Öğrencilerinde Psikosomatik Belirtiler ile Çocukluk Çağı Travmaları ve Bağlanma Stilleri Arasındaki İlişkide Psikolojik Dayanıklılığın Aracı Rolü
Authors: Taş İlayda , Akben Cantürk
Published: December 2024

Psikosomatik belirtiler, bireylerin psikolojik durumlarının fiziksel belirtilerle ortaya çıkmasıdır ve bu durum, özellikle çocukluk döneminde yaşanan travmalarla ilişkilidir. Bu çalışma, üniversite öğrencilerinde psikosomatik belirtiler ile çocukluk çağı travmaları ve bağlanma stilleri arasındaki ilişkiyi incelemekte ve psikolojik dayanıklılığın bu ilişkilerdeki aracı rolünü ele almaktadır. Bu araştırma nicel yöntemlerden tanımlayıcı tipte ve ilişkisel bir çalışmadır. Veriler kolayda örnekleme yöntemiyle toplanmış olup ölçümler öz-bildirim yöntemiyle elde edilmiştir. Çalışmada kullanılan sürekli değişkenler çocukluk çağı travmaları, psikolojik dayanıklılık ve psikosomatik belirtilerdir. Kategorik değişken olarak da üç boyutlu bağlanma stili kullanılmıştır. Bu stiller güvenli bağlanma, kaçınan bağlanma ve kaygılı-kararsız bağlanmadır. Çalışmada, çocukluk çağı travmalarının psikolojik dayanıklılığı düşürdüğü ve dolaylı olarak psikosomatik belirtileri artırdığı bulunmuştur. Ayrıca, güvensiz bağlanma stillerinin (kaçınan ve kaygılı-kararsız) de psikolojik dayanıklılıkla negatif ilişkiler gösterdiği ve dolaylı olarak psikosomatik belirtilerle pozitif ilişkiler gösterdiği tespit edilmiştir. Yüksek psikolojik dayanıklılığa sahip bireylerde bu etkinin hafiflediği bulunmuştur. Araştırmanın bulguları, eğitim süreçlerinde psikosomatik belirtileri azaltmaya yönelik psikolojik dayanıklılığı artırıcı programların geliştirilmesinin önemine işaret etmektedir. Eğitimcilerin ve sosyal psikolojinin uygulama alanlarında faaliyet gösteren araştırmacıların, öğrencilerin travmatik geçmişlerine duyarlı olmaları ve bu öğrenciler için uygun psikososyal destek programları geliştirmeleri gerektiği vurgulanmaktadır.
О требованиях к членам органов управления хозяйственных обществ
Authors: Косякин Игорь
Published: December 2024

Система требований к членам органов управления включает элементы, активно обсуждаемые в доктрине в последнее время. Исследование социально-групповых квот в коллегиальных органах управления является актуальным. В российском законодательстве и судебной практике до сих пор не решен вопрос о возможности квалификационных требований к лицам, входящим в состав органов управления. Предметом исследования в настоящей статье являются элементы системы требований к членам органов управления, вызывающие наибольшее число споров в науке и практике, — квалификационные требования (к стажу, образованию, деловым качествам) и квоты в коллегиальных органах управления, за счет которых устанавливаются требования к части мест. Используя общенаучные (анализ, синтез) и специальные юридические (историко-правовой, сравнительно-правовой, юридико-догматический, социологический) методы, автор выдвигает следующие гипотезы: поскольку по своей правовой природе отношения директора и общества являются гражданско-правовыми, последнее свободно в определении того, какими качествами должны обладать члены его органов (как и его контрагенты либо представители); вместе с тем возможно публично-правовое вмешательство путем квотирования мест в коллегиальном органе управления различными способами (установление квот для социальных групп, участие работников в управлении, включение представителей государства по «золотой акции», квотирование миноритарных акционеров и введение независимых директоров). В статье обосновывается соотношение необходимости квалифицированного управления и корпоративной демократии, оцениваются различные основания введения квот (как в общем, так и применительно к российскому корпоративному управлению), предлагается применение лучших практик корпоративного управления (введение «идеальной процедуры избрания», «подталкивание» посредством описания лучших практик, включение лиц, не являющихся членами совета директоров, в комитеты совета директоров либо создание отдельных совещательных органов). Выдвигаются параметры, с помощью которых можно проверить обоснованность введения квоты и ее влияние на заинтересованных лиц хозяйственного общества.

XIX. yüzyıl Osmanlı Rus savaşlarında belirleyici olan unsur sadece Osmanlı ordularının modernize edilemeyişi ve askeri teknolojilerini yenilemeyişi değildir. Aynı zamanda Rus ordularının da teknik, taktik ve psikolojik harp unsurları bakımından kendilerini geliştirmiş olmalarıdır. 1768-74 savaşı sonrası imzalanan Küçük Kaynarca barışı ile Rusların Karadeniz ve Kafkasya bölgesine olan ilgisinin giderek bir stratejiye dönüştüğü bilinmektedir. Özellikle Karadeniz’in doğu kıyılarında elde ettiği üstünlükler sonucu Kafkasya siyasetinde daha başat bir rol üstlenmeleri kaçınılmaz olmuştur. Bu süreçte özellikle güney Kafkasya’daki iki Müslüman devlet olan İran ve Osmanlı’ya karşı elde ettiği iki önemli zafer ile bölgenin hâkim aktörü konumunu güçlendirmiştir. Rusların güney Kafkasya bölgesindeki hâkimiyetlerini perçinleyecek olan 1828-29 savaşı daha sonraki 1855-56 ve 1877-78 savaşları için de mihenk taşı mahiyeti arz etmektedir.
Bu çalışmada askeri tarih çalışmaları kapsamında 1828-29 savaşının Osmanlı savunma ve lojistik sistemleri çerçevesinde değerlendirilmesi yapılacaktır. Osmanlı savunma anlayışının değişim ve dönüşüm içerisine girdiği bu dönemde müstahkem kale ve mevkilerin savunma kabiliyetlerinin artırılmasına yönelik girişimlerden daha ziyade askeri harcamaların lojistik ve tedarik unsurlarına yönelmesinin savaşların seyrine nasıl yön verdiği ortaya konulmaya çalışılacaktır. Ayrıca mevcut literatürde vurgulanan Rus ordularının stratejik üstünlük ve doğru taktikler ile Osmanlı ordusuna üstünlük kurduğu tezinin eleştirisi yapılacaktır. Kür ve Aras vadilerini mevcut kale ve sabit mevzilerle müdafaa etmenin zorluğundan dolayı mı? Rusların süratli ve baskın tipi manevralara daha çok yöneldiği sorularına cevap aranacaktır. Bu doğrultuda Osmanlı Arşiv kayıtları arasında bulunan ve 1828 savaşı öncesinde Ahıska kalesi ve çevresindeki kalelerin tamir ve teçhiz edilmesine yönelik hazırlanmış keşif defterleri üzerinden Anadolu’nun giriş kapısı konumunda olan vadinin elde tutulması için belirlenmiş stratejinin anlaşılması planlanmaktadır.

In this study, Paulo Coelho's The Alchemist, published in 1988, is examined in terms of the characteristics of the industrial period, and the interaction between industry, society, individuals, and knowledge is analyzed. In The Alchemist, the increasing importance of knowledge and books is emphasized, and the value of knowledge and written sources is symbolized by the main character, Santiago, standing in front of a collapsed church. This symbolizes the transition from medieval thought to scientific and rational approaches in the industrial period. While the ruined church reflects the negative aspects of the past, the large fig tree in front of it represents life and rebirth.
The main character embarks on a journey by selling his sheep to fulfill his dreams, acquiring new knowledge and skills in the process. Shepherding is portrayed as an educational profession and is associated with religious elements. Santiago’s desire to deepen his knowledge and improve himself, his solitude, and his expression of the joy of life through books reflect the industrial society's emphasis on individuality. A shepherd who reads books and has access to information and innovations demonstrates the transformation of professional roles in society and the democratization of access to knowledge.
Furthermore, the positive aspects of openness to change and innovation, the importance of knowledge and practical experience, are highlighted in the novel, and the processes of wisdom and individual development are analyzed.

Mimari anlamda bir yapının temel unsurlarından biri olarak tanımlanabilecek kapı ve eşik, insan yaşamında tarih boyunca çeşitli form değişikliklerine uğramış olsa da bugün de "ev" kavramının anlam sınırları içinde önemli bir yere sahiptir. Mekânı iç ve dış olarak ikiye ayıran kapı ve onun bir öncüsü olarak eşik, geçmişin kültürel mirasında öne çıkan çeşitli sembol ve değerlerin gündelik yaşamın mekânsal örgüsünde simgesel çağrışımlarını taşımaktadır.
Bu çalışmanın amacı, insan, mekân ve kimlik ilişkisinde çok yönlü bir hafıza bileşeni olarak kapıları ve eşiklerini Urfa geleneksel ev kapıları örneği üzerinden incelemek ve değerlendirmektir. Bu kapsamda, Urfa şehir merkezinde yer alan ve Osmanlı’nın son dönemine ait evlerin giriş kapıları tespit edilmiştir. Çalışma, tarihi evlerin giriş kapıları ile mimari özellikleri açısından özgün olanlarla sınırlandırılmıştır. Çalışmada şehir, mahalle ve sokak ekseninde toplumsal hayatın biçimlenişi ele alınmış, kapı ve eşik kavramlarının tanımı, anlamları, mimaride yapı ile ilişkisi ve özellikle evle olan bağlantısı vurgulanmıştır. Evlerin giriş kapılarında yer alan düşünce, inanç ve estetik unsurlar incelenmiş ve bu unsurlar ikonografik analizlerle değerlendirilmiştir. Sonuç olarak, Urfa şehir kültürü bağlamında ev kapılarının tarihi kimliği incelenmiş ve literatüre katkıda bulunulması amaçlanmıştır.
THE KINGDOM OF IMERETI ACCORDING TO „TSKHOVREBA MEPETA” (LIFE OF KINGS) BY SEKHNIA CHKHEIDZE

Verifying written sources, especially the works of the old chroniclers and specifying their historical and source study value is one of the main tasks of historical sciences. No complete A complete historical and source-scientific study of the works by Sekhnia Chkheidze, a Georgian historian of the of the XVII century and the first third of the XVIII century has not been carried out until now. Such a “delay” is partially caused by the attitude of Ivane Javakhishvili, the founder of the modern Georgian historical school, to the works of Sekhnia Chkheidze. Our goal is to study the reliability of the records by Sekhnia by means of comparison of the different kind of historical sources, records of Georgian and foreign authors and data from the works by Sekhnia Chkheidze. The article analyses the records of the author about the kingdom of Imereti history of XVII-XVIII centuries out of the mentioned extensive research. Georgian historiography is dominated by the view that the focus of Sekhnia Chkheidze's attention was only on the historical processes taking place in the Eastern Georgia, and he was not familiar with the political situation in the Western Georgia. On the basis of the cyclical source scientific research conducted by us, the present paper shows that S. Chkheidze was well aware of the political processes taking place in the Western Georgia, especially in the Kingdom of Imereti.
Reportedly, Georgia was divided into several kingdom-prinicipalities in the II half of the XV century, it was a long process, first, Samtskhe-Saatabago, then Kakheti Kingdom separated from the united Georgia, later, Kartli and Imereti were also formed as separate kingdoms. The process of disintegration was deepend in the XVI century, Imereti Kingdom had started dividing into several prinicipalities like Samegrelo, Guria, Abkhazia and Svaneti in the second half of the 50s. Despite such a condition the fight for restoring of the country unity had never stopped. Sekhnia Chkheidze, treasurer and historian of the royal court of Kartli, could clearly see that Western Georgia faced the most difficult situation in the case of unification of the country. A chronicler highlights the attempt of progressive kings of Kartli (Vakhtang V, Giorgi XI, Archil and Vakhtang VI) to enhance and strengthen their influence on the whole region with support of Georgians from the Western Georgia.

Marine carbon observations (MCOs) provide essential data to trace historical and current changes in marine carbon storage and fluxes that ultimately feed into the Global Carbon Budget and the Intergovernmental Panel on Climate Change report. Therefore, MCOs play a key role in informing global climate policy as well as ocean governance. However, they only achieve this potential if multiple sources of observations are combined and analyzed jointly. This implies an immense coordination effort by the international MCO community which developed, e.g., joint standards for the collection of (meta‐)data, quality control processes, data platforms, etc. This article traces the value chain of MCOs, concretely for CO2, from data collection to the Intergovernmental Panel on Climate Change report. Based on an interdisciplinary research project, the study illuminates which structures and practices the marine carbon community has developed to integrate different observations and measurement technologies, starting from German research institutes and agencies and expanding to the European and international networks to which they contribute. Combining a social network analysis with qualitative insights from in‐depth interviews, the article identifies key information providers and brokers and pinpoints systemic vulnerabilities, e.g., where connections between observation networks or data platforms are maintained based on personal relationships or ad‐hoc interactions rather than automated data submissions, or where temporally limited third party funding threatens the continued existence of the observation network.

This study aimed to identify mineralized zones within a sedimentary structure, including its discontinuities such as layer boundaries, and faults. The Loza-N model Deep Ground Penetrating Radar (DGPR) system with a 25 MHz antenna was employed to achieve a target depth of up to 200 meters. The investigation was conducted on mine terraces, berms, and the flat northern part of the Mehdiabad calamine mine located in Yazd, Iran. A total of 23 profiles were surveyed. Data acquisition for some profiles involved parallel transects, while others utilized a series approach where the transmitter and receiver antennas were progressively moved along the ground surface. The processed radargrams from selected profiles were compared amongst themselves and with borehole data collected along the same profiles. The geological structure was successfully visualized using two different software programs. Krot software effectively distinguished all limestone units and their zonation. By combining the GPR data with borehole results, it was possible to identify potential ore mineral zones within the marly units. Based on the DGPR traces at borehole locations, high-grade ore minerals in the marly limestone exhibited positive phase and amplitude values, represented by intermediate to maximum color hues. Conversely, light green and light gray limestone containing iron oxide and calcite veins displayed negative phase and amplitude values, with negative zero to intermediate color hues. Dark green limestone showed the most negative phase and amplitude values, reflected by the maximum negative color hues. Finally, light red limestone, likely containing lowgrade ore, presented positive but minimal phase and amplitude values, visualized by positive minimum color hues.

Published: December 2024

This paper presents a laboratory and numerical study to determine three hydraulic characteristic curves of a swelling material (soil or rock) in which montmorillonite is the predominant type of mineral. The first, the soil-water characteristic curve, represents the relationship between suction and moisture content that needs to be defined to solve the water flow problem and the accompanying change in the volume of the swelling unsaturated porous medium. The second curve presents hydraulic conductivity as a function of saturation or suction. The third curve represents the relationship between the volume change and the moisture content of the swelling material. These curves are crucial for understanding water flow and volume changes in swelling materials, with this study focusing on wetting regime behaviour. The aim of this research was to establish reliable methods for the definition of the hydraulic properties of the swelling material and to verify a proposed swelling model. While the swelling material shows significant hysteresis between the drying and wetting regimes, the hydraulic conductivity function shows little or no hysteresis between drying and wetting paths at equal moisture contents (coefficients).
