Authors: Jijón Hernández Alex Abraham , López Calvo Herwing Zeth , Martínez Barrita Rolando
Published: June 2024

En el presente artículo se evaluaron los efectos de la adición al concreto de ceniza de bagazo de caña de azúcar (cbca) en combinación con agregados reciclados de arcilla termoexpandida (arat). Con este propósito, se diseñaron un total de nueve mezclas, considerando remplazos de cemento portland de 0%, 10% y 20 % por cbca y sustituciones de agregado grueso por 0%, 50% y 100 % de arat. Considerando dichas combinaciones, se elaboraron un total de 81 especímenes de concreto con una relación agua/materiales cementantes de 0.50 en todos los casos a edades de 7, 14 y 28 días. Los resultados revelaron que, a medida que aumentan los contenidos de cbca y arat, se reducen, aunque en diversos grados, las propiedades mecánicas en todas las mezclas de concreto.

Published: June 2024

O comportamento de cidadania organizacional ocorre quando os trabalhadores assumem atitudes e executam tarefas que superam as funções formalmente associadas aos cargos que exercem. Elevados níveis de comportamento de cidadania organizacional sugerem presença de aspetos positivos no ambiente de trabalho. Nesse contexto, o objetivo deste estudo é analisar a relação entre comportamento de cidadania organizacional, tendo como preditores a satisfação no trabalho e a intenção de rotatividade. Para tanto, foi realizada uma survey com amostragem não probabilística por acessibilidade, que contou com a participação de 102 empregados de uma empresa pública no estado do Pará. O questionário reuniu as escalas Short Index of Job Satisfaction; Escala de Intenção de Rotatividade e Escala de Comportamento de Cidadania Organizacional. Os dados foram tratados com modelagem de equações estruturais (PLS-SEM) e os resultados confirmaram que a satisfação com o trabalho influencia positivamente no comportamento de cidadania organizacional e negativamente na intenção de rotatividade. Por outro lado, não foram encontradas evidências estatísticas de que a intenção de rotatividade influencie no comportamento de cidadania organizacional. As conclusões recomendam o aprimoramento de políticas de gestão de pessoas para acompanhar, manter ou, se possível, aumentar a satisfação com o trabalho e, com isso, reforçar tanto o comportamento de cidadania organizacional, quanto reduzir a intenção de rotatividade, melhorando o desempenho na organização estudada.
Palavras-chave: gestão de pessoas; administração pública; cidadania organizacional; equações estruturais.

Long-term impacts of COVID-19 on stress and depression among teachers: Differences by gender
Authors: Huseth-Zosel Andrea , Crary Sarah , Orr Megan
Published: June 2024

This article explores the impact of changes in teaching modalities resulting from the COVID-19 pandemic on the mental health of K-12 teachers, by gender, during the first year of the pandemic. Teachers from a random sample of K-12 schools in North Dakota and Minnesota were surveyed in April 2020, October 2020, and March/April 2021 about their current levels of stress and depression, as well as the frequency with which they experienced certain physical conditions. One-way analysis of variance and multiple regression were used to compare time points for each of the outcomes by gender. Female teachers were more likely to experience higher levels of stress than male teachers, while male teachers were more likely to experience higher levels of depression than female teachers, with spikes in stress and depression levels experienced by both males and females in Time 2. Additionally, physical symptoms were more likely to be experienced by female teachers, with Time 2 respondents overall reporting significantly higher proportions of physical symptoms than Time 1 or Time 3 respondents. Consistently experiencing heightened levels of stress and depression can lead to burnout for teachers. School districts need to monitor stress, especially among females, and depression, especially among males, to recognize the difference in experience for each gender in the teaching profession, as well as provide supports and resources to their teachers to help them in coping with these mental-health issues.
In Search for Alternatives to German Domination: The Construction of the Maritime Past in Latvian and Lithuanian National Historiography
Authors:   Institute of Baltic Region History and Archaeology, Klaipėda University, Kulevičius Valentinas
Published: June 2024

In the first half of the 20th century, all the states that emerged on the east coast of the Baltic gained access to the sea. Each tried to utilise this to strengthen their economies, but contemporaries had different views on their potential to do so. One example is that the Latvians were labelled as a maritime nation, while the Lithuanians were portrayed as a “continental” nation. This is sometimes still the case today. The research presented in this article shows that despite this judgement, the need to create images of the maritime past of the Latvian and Lithuanian nations manifested in both cases through the historiography that influenced modern national identities. The article focuses on the different representations of the maritime past used by the Latvian and Lithuanian national movements in the late 19th and the first half of the 20th century and examines the origins of these representations as well as the contexts in which they were instrumentalised. The research shows that although the images were different, Lithuanian and Latvian historians used similar strategies to create and disseminate them. These included retrospective identification with mediaeval and early modern societies and attempts to use images of the maritime past to find alternatives to German domination in the region.

Co-worker incivility and task performance: The mediating effect of psychological empowerment
Authors: Aruoren Emmanuel Ejiroghene , Igemohia Mohammed , Igemohia Fidelia
Published: June 2024

It is widely acknowledged that workplace incivility (WI) is a serious issue that negatively affects employee performance (EP). This study investigated whether psychological empowerment (PE) mediated the link between employees’ task performance (TP) and co-worker incivility (CI). The study adopted a cross-sectional survey design, with a population of 307 employees of two ministries in Delta State, Nigeria. Using Yamane’s (1973) formula, 186 was determined as the sample size. After a week, 145 copies of the questionnaires were fully completed and retrieved. Hypotheses were tested using structural equation modeling (SEM). The results showed that while CI was positive and significantly related to PE (β = 0.561, p < 0.05), it was negative and significantly related to TP (β = -0.422, p < 0.05). PE was positive and significantly related to TP (β = 0.133, p < 0.05). Moreover, a partial mediating role for PE was observed in the relationship between TP and CI. Based on these findings, it was recommended that the Delta State Civil Service Commission should put in place policies that will mitigate the occurrence of WI as it adversely affects EP. In addition, employees should be empowered psychologically to enable them to manage the detrimental effects of WI.
Guessing quantum states from images of their zeros in the complex plane
Authors: Janowicz Maciej , Zembrzuski Andrzej
Published: June 2024

The problem of determining the wave function of a physical system based on the graphical representation of its zeros is considered. It can be dealt with by invoking the Bargmann representation in which the wave functions are represented by analytic functions with an appropriate definition of the scalar product. The Weierstrass factorization theorem can then be applied. Examples of states that can be guessed from the pictorial representation of zeros by both the human eye and, possibly, by machine learning systems are given. The quality of recognition by the latter has been tested using Convolutional Neural Networks.

Suppression of Hyperglycemia-Induced Insulin Resistance by Rapanone Isolated from Connarus Ruber
Authors: S Kawaguchi
Published: June 2024

Although it would be ideal if insulin resistance due to a persistent hyperglycemic state could be prevented by consuming particular foods, to the best of our knowledge, no foods with such effects have as yet been reported. Connarus ruber (CR) extract, previously indicated to be effective against diabetes, was investigated in this study to ascertain whether it can inhibit the induction of insulin resistance in human hepatoma-derived HepG2 cells. Insulin resistance can be induced in cells by cultivating under hyperglycemic conditions. HepG2 cells were cultured for 24 and 48 h with 1.25 µg/mL of CR extract and its components, rapanone and embelin, at 1.25 and 5 µg/mL, followed by the induction of insulin resistance by hyperglycemic conditions. The results revealed a decrease over time in the glucose concentration of HepG2 cells, indicating that insulin resistance was inhibited in these cells. However, when HepG2 cells, already insulin resistant owing to previous exposure to hyperglycemic conditions, were cultured for 24 and 48 h with CR extract containing rapanone and embelin at <10 µg/mL, the glucose concentration creased over time, indicating that insulin resistance was not affected under these conditions. The results suggest that insulin resistance is inhibited only when CR extract exposure occurs before exposure to hyperglycemia conditions and CR cannot induce recovery from insulin resistance. Thus, this study indicates that CR extract, with rapanone and embelin as active ingredients, could be used as a functional food to reduce the risk of developing type 2 diabetes mellitus as a result of chronic hyperglycemia.
Haematology in Juveniles of African Catfish (Clarias gariepinus) Exposed to Primextra Gold® (Atrazine) Herbicide
Authors: JI* Odo
Published: June 2024

The widespread increase of pesticides application in crops frequently leads to the contamination of the fresh water ecosystem. One of the most commonly used pesticides in Nigeria is Primextra Gold® (atrazine) herbicide. The aim of this study is to evaluate the toxicity of Primextra Gold® (atrazine) on the juveniles of the African catfish, Clarias gariepinus. The toxicity was carried out using 120 healthy fish that were divided into six treatments (control inclusive) with each treatment having ten fish and the setup was replicated. The fish were exposed to 0.00 (control), 0.15, 0.29, 0.44, 0.59 and 0.74mg/L concentrations of Primextra Gold® (atrazine) for two weeks. During the exposure period, physicochemical parameters were determined. After two weeks of the experiment, blood samples were collected for heamatology using standard methods. Data obtained were subjected to ANOVA at P<0.05using Minitab 17. Results of the physico-chemical parameters of water exposed to concentrations showed that there was a significant decrease (P<0.05) in the amount of dissolved oxygen with increase in concentrations of the herbicide while pH, total dissolved solids (TDS) and electrical conductivity increased. Temperature showed no significant difference (P˃0.05). Haematological parameters reduced significantly (P<0.05) in amount of PCV, Hb and RBC with increase in concentrations. Meanwhile WBC increased significantly (P<0.05) with increase in concentration. A haematological change observed during the exposure is an indication of anaemia, leukocytosis, and haemoglobinaemia. The study revealed that Primextra Gold® (atrazine) was moderately toxic to Clarias gariepinus juveniles and affected the haematology as well as Physicochemical parameters of the exposed water. These results show that the contamination of water by pesticides either directly or indirectly could be lethal to fish or may reduce fish productivity. Elevated concentrations of undesirable chemicals in edible fish tissue can affect the health of humans eating these fishes.

Published: June 2024

“O Ensino Público no Congresso Nacional. Breve Notícia” written by Primitivo Moacyr, and published in 1916 is this paper’s subject. Our work focuses on the perspective of studies of its materiality according to assumptions of book and lecture history referred to by Roger Chartier and Robert Darnton. A comparison between the chronicles published in the newspaper “Jornal do Commercio”, and book’s content was favoured expecting to find a ipsis litteris reproduction. Different amendments were identified as a result of editing process, and others as a result of each plataform used by the author. We concluded besides these changes it is crucial to mention that each plataform requires a distinct way of reading, a diverse audience (implicit reader), and its express author intention to share intellectual practice at that time. Subject analysis presented here intends to contribute to current studies on the intersection of histories of education, book, and press.

The article presents the results of studies of the influence of technological factors (clinker factor of cements, grain composition of aggregates, cement consumption in concrete, modifier additives) on technical and environmental indicators of concrete efficiency. It has been shown that in combination, the parameters of clinker and CO2 intensities characterize the clinker efficiency of concrete, which can be improved by replacing part of the clinker in mixed cements with active mineral additives. Optimization of the granulometric composition of fine and coarse aggregates and the use of superplasticizers of the polycarboxylate type ensure the formation of a dense microstructure of the cementing matrix, which allows to increase the strength of concrete by 1-2 classes with an unchanged cement consumption and helps to reduce the CO2 emission rate. With the correct combination of various technological factors affecting concrete mixtures, a real opportunity is created to produce modern low-carbon concrete that meets the requirements of sustainability.

Published: June 2024

In this article the specific heating and cooling capacity of the ceiling TABS was determined. The step of tube laying varied and was 10, 15, 20, 25, and 30 cm. Determination of the specific heating capacity was carried out for th /tc = 35/31; 36/32; 34/30 oC. The determination of the specific cooling capacity was carried out for tcold /theated = 15/18; 16/19; 16/20oC. The radiant heating system based on ceiling TABS allows providing the necessary heating capacity to fully cover the heat loss of the room. The maximum values of the carrier temperature are th /tc = 34/30 oC. In the warm period, the ceiling TABS does not allow to provide the necessary cooling capacity of the room. Thus, the greatest cooling capacity of TABS is observed at coolant parameters tcold /theated = 15/18оC, which allows covering about 70% of the estimated heat gains of the room. Therefore, during the hours of peak heat gains an additional cooling device should be used in the room.

Financial Inclusion and Human Development: Evidence from African Countries
Authors: Mani Paul , Nyamute Winnie , Ondigo Herick
Published: June 2024

Africa is a continent that has experienced significant economic and developmental challenges, including high levels of poverty, income inequality, and limited access to financial services. According to a report by the World Bank in 2020, Africa has the lowest rate of financial inclusion in the world. Financial inclusion is important in that it contributes to the achievement of 7 out of 17 sustainable development goals provided by the United Nations. Apart from having low levels of financial inclusion, African countries are also ranked lowest in terms of human development. There is a growing consensus that financial inclusion is essential for economic growth and human development. This study examined the effect of financial inclusion on human development in African countries. To achieve the research objective, the study employed a panel longitudinal research design that involved collecting secondary data for the period between 2011 and 2020 on an annual basis for each of the 54 African countries. Findings indicate that financial inclusion, measured by bank branches, ATMs, deposit accounts, and loan accounts, has a positive and significant effect on human development in African countries. The study concludes that fostering financial inclusion is crucial for promoting human development in African countries. Policy implications include the need to enhance access to banking services, along with developing supportive regulatory frameworks. The study also emphasizes the need for policymakers to prioritize inclusive finance and implement targeted interventions to address the specific challenges and opportunities within each context.

Optimizing Patient Safety and Security Management in Zambian Mental Health Facility: A PDSA Quality Improvement Study
Authors: Tsarkov Anatolii , Fernandez Andréa Ferraz de Arruda , Ribeiro Marcelo Leite , Petlovanyi Petro
Published: June 2024

Delivering specialized and top-tier psychiatric care necessitates an intricate and well-thought-out plan focusing on the safety and security of both healthcare professionals and patients. In the realm of mental health, particularly in specialized clinics and hospitals where patients may require admission and intricate treatment plans, the safety and security of the healthcare environment are paramount. It is crucial to ensure the comprehensive and tailored protection of mental health workers, particularly those operating in shift patterns. A well-devised strategy can significantly enhance the overall safety and security within a healthcare facility, potentially streamlining operational costs while minimizing both immediate and long-term risks associated with breaches in safety and security protocols. The aim of this research was to bolster safety and security protocols within mental health treatment establishments by identifying and addressing operational hurdles faced by ancillary mental health staff. To achieve this, the study implemented the Plan-Do-Study-Act (PDSA) cycle, a cornerstone methodology in quality management systems. The PDSA cycle’s pragmatic ethos encourages a methodical, iterative approach to integrating new methodologies into any process, particularly those aiming to elevate security and safety standards. This model was specifically employed to refine the functioning of the security and safety department at a private mental health facility in Lusaka, Zambia. The anticipated outcome is that this approach will not only safeguard the immediate and future well-being of healthcare personnel and patients but also foster a holistic and efficient operational environment for mental healthcare services.
Papua Conflict: An Article Review from the Best Conflict Resolution Method
Authors: Merina Bresca
Published: June 2024

This article is aimed to review conflict resolution process of Armed Criminal Group in Papua (KKB). This study is a scientific-article review using comparison technique, which compares horse trading method, counter-insurgency (COIN) model, and Military Operations Other Than War (OMSP) to later review the best method in conflict resolution and renew or develop it. This study starts from revealing the background of Armed Criminal Group (KKB) happening in Papua, and then discussing conflict resolution process referring to the separatist movement development from KKB using horse trading method, which is proven effective to resolve this conflict if it is supported by the trust between two parties to have a dialogue where both parties are allowed to deliver their purposes openly. It is different from the application of McCormick’s COIN strategy model which narrowly fails in resolving Papua conflict, and even is possible to create a chance of the new dynamics’ existence in its international dimension, so it is needed to have a new interpretation towards COIN model in Papua, which is by giving solution to conflict-root elimination instead of total elimination by military. Meanwhile, applying Military Operations Other Than War approach (OMSP) is mandatory which is done by every country in order to tackle separatism movements. By those three models mentioned earlier, several strategic steps are formulated later in conflict resolution of Armed Criminal Group (KKB) in Papua.
La presenza di Dante nell’ultima poesia italiana
Authors: Fantuzzi Matteo
Published: June 2024

Die Präsenz Dantes in der italienischen Lyrik ist eine weithin anerkannte Realität. Drei aktuelle Beispiele werden in diesem Artikel vorgestellt. Wenn einerseits in dem Band Suite Etnapolis (2019) von Antonio Lanza der Bezug zu Dante auf der inhaltlichen Ebene durch den Vergleich zwischen dem Einkaufszentrum Etnapolis in Sizilien und dem dritten Gesang des Inferno zum Ausdruck kommt, greift andererseits Isabella Leardini in ihrer Sammlung La coinquilina scalza (2004) Dantes narrative Struktur auf. Die Gedichte in Una stagione d'aria (2017), die Leardini selbst verfasst hat, stehen hingegen in der Art einer «zeitgenössischen Neuübersetzung» im Dialog mit den Dantes Versen. Giulia Martini scheint die Summe der beiden vorangegangenen Dichterinnen zu sein, indem sie sich Dantes Gedicht in der Sammlung Coppie minime (2018) sowohl inhaltlich als auch strukturell nähert, z. B. durch die Verwendung von Minimalpaaren und dem ugolinischen Hypotext.
Zu Fuß in der Menge
Authors: Götz Susanne , Kipke Harald
Published: June 2024

Um die Akzeptanz des Zufußgehens bei den Menschen zu erhöhen, sind neben den rein funktional-objektiven Einflussfaktoren, die von der Stadtplanung beeinflussbar sind, ebenso die vom Individuum empfundenen sensitiv-emotionalen Einflüsse zu berücksichtigen, die hier mit dem Begriff des Wohlbefindens umschrieben werden. Unter der Annahme, dass das persönliche Wohlbefinden in unterschiedlichen Umgebungssituationen eine wichtige Rolle für die subjektive Entscheidungsfindung für das Zufußgehen spielt, wurden leitfadengestützte Interviews in realen als auch virtuellen Umgebungen durchgeführt, um die Wahrnehmung und das Wohlbefinden der Befragten zu erfassen. Die Ergebnisse zeigen, dass bei einer Unterschreitung eines spezifischen Flächenangebots von 6 m2/Person bereits Anzeichen von Agoraphobie festzustellen sind, dass aber auch die Interpretation von Umgebungsreizen das Wohlbefinden beeinflussen kann. Dabei fühlten sich Frauen unter gleichen Umgebungsbedingungen im Durchschnitt unwohler als Männer, was weiteren Forschungsbedarf aufwirft. Es konnte zudem nachgewiesen werden, dass die deutschen Regelwerke zur Bemessung von Straßen den Aspekt des Wohlbefindens als Qualitätsmerkmal im Fußverkehr nicht ausreichend spiegeln. Einschränkungen zur Validität der Studienergebnisse liegen im Rahmen der Durchführung der Interviews in virtuellen und realen Umgebungen sowie in der Stichprobenzusammensetzung vor.

Zivilschutz in urbanen Räumen
Authors: Henninger Sascha , Junk Philipp
Published: June 2024

Vor dem Hintergrund der zunehmenden Häufigkeit und Intensität von Extremwetterereignissen wie Starkregen ist es notwendig, in städtischen Gebieten erneut ein flächendeckendes Warnnetz zur Alarmierung der Bevölkerung aufzubauen. Im Gegensatz zu ländlich geprägten Räumen sind viele dicht besiedelte Innenstädte in der Regel nicht mehr mit Sirenen ausgestattet. Angesichts der steigenden Anzahl von Gefahren, denen insbesondere die Bevölkerung in Ballungsräumen ausgesetzt ist, werden Warnmittel entwickelt, v. a. Warnmeldungen, die die Menschen individuell vor akuten Gefahren warnen können. Vielerorts fehlt jedoch ein flächendeckendes Netz erprobter Warnmittel. Ein solches Netz kann am effektivsten durch Sirenen realisiert werden, wobei der Aufbau in konkretem städtischem Kontext allerdings mit einer Reihe von Fragen und Problemen verbunden ist. So dürfen Sirenen eine bestimmte Lautstärke nicht überschreiten, um die körperliche Unversehrtheit der Passanten in der unmittelbaren Umgebung zu gewährleisten. Gleichzeitig muss das gesamte Beobachtungsgebiet durch das Sirenennetz mit ausreichender Lautstärke beschallt werden, damit die Menschen angemessen auf die Warnmeldungen reagieren können. Daraus ergibt sich eine Vielzahl von möglichen Standorten, die im Zuge der Analyse zu einem funktionierenden Netz zusammengefügt werden müssen, um abschätzen zu können, wo und in welcher Anzahl die Warnsysteme letztendlich platziert werden müssen.

Er zeigt, wie sich die Funktionseigenschaften der Oberflächenmikrogeometrie als statistisches Ensemble im Phasenraum darstellen lassen, deren kanonisch konjugierten Koordinaten aus den Dichteverteilungen von Höhen- und Steigungswerten gebildet werden. Er betont, dass die Limitierung topografischer Messverfahren hinsichtlich der Messung von Oberflächensteigungen die Anwendung von kontaktmechanischen Modellen in der Praxis erschwert. Hierfür wird ein ergänzendes Messprinzip vorgestellt und auf Beispiele von praxisrelevanten tribologischen Funktionsflächen angewendet.

A particularly demanding contact in axial piston pumps is the one between cylinder block and valve plate. The tribological behavior of the contact can be changed by a run-in process. Publications on fast and efficient run-in are rare as this knowledge is often considered confidential. For this paper, tests have been carried out on a disc-on-disc tribometer to examine the run-in behavior of a material pairing and to identify suitable parameters for run-in. A methodology has been developed which can be used to find the optimal normal load and rotational speed for the run-in process to shorten the run-in time significantly.

Wind turbines (WT) are a key technology towards a carbon neutral energy production worldwide. Currently about 30 % of the Levelized Cost of Electricity (LCoE) consist of service and maintenance. Critical components are the main roller bearings which have a failure probability between 15 and 30 % within 20 years. Main bearing replacements are expensive maintenance procedures because an external crane is needed which cost about $250.000 per day for offshore WTs. Hence, a discussed countermeasure within the wind industry is to use segmented plain bearings in future WTs. These types of bearings allow an up-tower sub-component wise replacement of faulty parts without the need to dismantle the whole drivetrain. Therefore, the Chair for Wind Power Drives (CWD) developed, tested and validated a segmented conical plain bearing concept for the use as a main bearings for WTs.

To function properly common plain bearings need a minimum clearance to allow the formation of a convergent lubrication gab. This initial clearance negatively influences run-out, as the shaft con move freely within the limits of the clearance. As WT drivetrain concepts become more integrated, main bearings for WTs need to fulfill higher requirements regarding the allowable run-out of the main shaft. Therefore, a fundamental design challenge arises for plain bearings as rotor main bearings. One approach to reduce run-out for roller main bearings is to use preloaded tapered roller bearings. For common plain bearings however preloading is not possible. However, the concept of preloading was successfully transferred to the flexible conical plain bearing concept developed at the CWD and the main shaft run-out severely reduced. In this work the feasibility of a preloaded flexible conical plain bearing as a WT rotor main bearing is evaluated and the advantages and disadvantages contrasted.

This study aims to examine the effects of explicit-reflective nature of science (NOS)
activities on science teacher candidates’ views on the nature of science and self-efficacy beliefs about teaching the nature of science, using a single-group pre-test-post-test experimental method. The research sample included 120 science teacher candidates studying at public universities in Turkey’s Marmara and Central Anatolia Regions during the second semester of the academic term 2017-2018. Data were collected using the “Views Questionnaire on the Nature of Science-VNOS-C” and “Self-Efficacy Scale for Nature of Science Knowledge and Instruction”. For data analysis we used statistically related samples t-Test, descriptive statistics using frequency (f)-percentage (%) and content analysis. Participants’ beliefs for teaching the nature of science positively changed after the applications (p .01). Also, views in all dimensions of the nature of science have increased at an “acceptable” level as well. According to the findings, nature of science activities enhanced students’ views about the nature of science and their self-efficacy beliefs about tutoring the nature of science.

The aim of this study is to classify the subjects and skills of middle school mathematics course in the context of MATH Taxonomy and to determine their relations. For this purpose, the questions and answers related to the mathematics subtest of a national exam were analyzed over the answers of 20154 students. The study continued with the analysis of the data set containing the answer patterns of the students according to the rules of association of data mining methods by using RapidMiner program and FP-Growth algorithm. The results show that students with any level of skill in MATH taxonomy related to mathematical skills could perform skills in subcategories at a high rate. Students who have attainment in the learning areas provided later in the mathematics program had a high rate of knowledge in the previously provided learning areas. However, this result is not valid for Probability of Simple Events.
The Image of Mihai Viteazul in 19th-Century Romanian Paintings

Published: June 2024

The Image of Mihai Viteazul in 19th-century Romanian Painting. The Romanian artistic movement of the 19th-century assisted the political endeavor of national legitimization by establishing the Romanian identity, in its various forms, through art. By adapting the example of their neoclassical and romantic counterparts they depicted various patriotic symbols on their canvases in order to appeal both to the population, from a visual standpoint, and their inherent political cause: obtaining independence and unifying the historical Romanian provinces. Such unity was first achieved by the historical figure of Mihai Viteazul, a Wallachian prince of the late 16th century. As a consequence, his figure became one of the main motifs illustrated in the art of the time, being closely tied to the concept of Romanian historic identity. The artists underwent a process of research in order to represent and bring forward a faithful image of the ruler, and some of his greatest achievements. Both historical and literary sources were approached, resulting in a diverse body of paintings, which will be discussed in the present article. The research aims to establish the sources on which the various artworks were based, the accuracy of the represented message with respect to the historical background of the ruler as well as the various stylistic approaches of the artists in question.

The Museum as a Catalyst of Community. Case Study: The Exhibition Imagining Futures: Urban Comics from ArtiViStory Collective at the Art Museum in Cluj-Napoca. The present article aims at illustrating the role of the contemporary museum as a conscious central stakeholder that strengthens the community and connects in the era of participatory culture with different types of audiences. Built in two parts, the article points out the main concepts of the new museum philosophy as explored in the expertise in the field and brings on a case study that focuses on the analysis of the cultural mediation program built for an original thematic exhibition, centered around the exploration of the urban future and having as its conceptual stake to draw the viewer into a process of reflection on the different ways of perceiving the surrounding society. Understanding social issues, remembering the past, exploring the ecosystem, acting on change and imagining futures are the invisible problems launched for debate through the creative laboratory of the members of the ArtiViStory Collective whose artworks could be explored within the exhibition. Their visual narratives, gathered in the various sections of the exhibition, have invited the viewers to respond to a series of questions that envisage the role of art in the community, the way we perceive the world around us, the stories that can be told about our past, the need for engaging young people into building inclusive communities or the way we can imagine our future. Through a wide variety of formulas for exploiting the potential of the graphic imaginary (visual documentaries, comic strips, animations, sequential illustrations), the exhibition offers an overview of this space of creative investigation of the urban imaginary and social identity, rendering sequential art not only as a tool of representation but as a catalyst for activating the collective imagination, which can serve to coagulate the common interests of the community. At the same time, the cultural mediation program conceived for the exhibition is an important component that creates engagement and participation of young audiences in a discourse on the future of our community.
