Leadership styles and organisational communication in selected public universities in Uganda
Authors: Turyahikayo Wilberforce , Mugizi Wilson , Kasule George Wilson
Published: July 2024

This study aimed to assess the impact of leadership styles on organisational communication in selected public universities in Uganda. Specifically, the study examined the influence of transformational and transactional leadership styles on organisational communication within these universities. The four public universities included in the study were Kyambogo University, Gulu University, Busitema University, and Mbarara University of Science and Technology. A correlational research design was employed, and data was collected from a sample of managerial staff, namely administrative and academic heads, using a self-administered questionnaire. Descriptive statistics and partial least squares structural equation modelling (PLS-SEM) were used to analyse the data using SmartPLS. The descriptive findings indicated that the organisational communication within the university was satisfactory, and the utilisation of transformational leadership styles by the leaders was high, while the use of transactional leadership styles was moderate. The findings from the Structural Equation Modeling confirmed that both transformational and transactional leadership styles had a positive and significant impact on organisational communication, while the passive-avoidant leadership style had a positive but insignificant impact. As a result, it was concluded that while transformational and transactional leadership styles are crucial for enhancing organisational communication in public universities, the passive-avoidant management/laissez-faire style is not. The study recommended that university leaders should emphasise the use of both transformational and transactional leadership styles to improve organisational communication. This study's implication is that it identifies the leadership styles necessary for enhancing organisational communication in universities.

In order to provide information on the current knowledge about the native fish Dormitator latifrons and identify the gaps that must be filled to achieve correct resource management, a scientometric study was carried out using different scientific databases. A total of 103 publications were registered between the years 1972 and 2021. Results indicate that the species has been addressed since 2001 with less than one publication per year, with 2008 being the year with the highest number of publications (10). The main topics addressed were ecology, physiology, and parasitology of fish. The available knowledge generated about the species is concentrated in 68 journals, with Mexico as the most productive country, followed by USA and Ecuador, and the most productive research centers about this fish were Mexico’s Instituto Politécnico Nacional and Universidad de Guadalajara. A total of 285 authors were detected contributing knowledge to the species, with Violante-González in the top with ten publications. The co-authorship co-occurrence maps suggest there is no solid collaborative relationship between the scientific community and that the information generated is insufficient for conserving and exploiting this fish. It is essential to increase the study of thematic areas that allow their comprehensive management in the medium term; topics like reproduction in captivity, aquaculture, and nutrition must be addressed in the future to assure a sustainable use of this resource.
Effect of temperature on the incubation, growth, survival, and presence of skeletal deformities in larvae of the clownfish Amphiprion ocellaris (Pomacentridae) under rearing conditions

Published: July 2024

The results of the effect of five different incubation temperatures on the development of clownfish (Amphiprion ocellaris) larvae are presented. This ornamental species is widely marketed worldwide and is reared in captivity at CIAD to meet the demand in the domestic market. The experimental work was carried out over 30 days post-hatching to observe the temperature's effect on the development of the larvae's vertebral column and caudal complex. The eggs were incubated at 26, 28, 30, 32, and 34°C. The percentage of hatching, survival, growth, and the presence of skeletal malformations were evaluated. Hatching and survival percentages did not show significant differences between treatments. Regarding growth, there were significant differences between treatments, with organisms showing slower growth at 26°C and larger sizes at 34°C. The highest percentage of malformations occurred in larvae cultured at 34°C, with lordosis being the most frequently observed deformity among the treatments. Therefore, it can be concluded that the optimal temperature range for cultivating and harvesting quality A. ocellaris organisms is between 28 and 30°C.
Population dynamics of Penilia avirostris and Pseudevadne tergestina (Diplostraca) in the Veracruz Reef System National Park, southwest Gulf of Mexico

Published: July 2024

The present study aimed to evaluate the ecology considering distribution, abundance, population structure, and fecundity of the marine diplostraceans Penilia avirostris and Pseudevadne tergestina in the Veracruz Reef System National Park, southwest Gulf of Mexico. Surface samples were collected with a 300 μm mesh plankton net at 26 sampling sites in June, August, October (2011), May (2012) and June (2013). Temperature, salinity, and dissolved oxygen were measured in situ. The temperature range was 26.53 ± 0.41 and 29.29 ± 0.27°C, salinity between 33.43 ± 0.49 and 35.91 ± 0.09, and dissolved oxygen between 2.92 ± 0.08 and 6.56 ± 0.08 mg L-1. P. avirostris and P. tergestina presented the highest density, with 2200 ind 100 m-3 in June and 5980 ind 100 m-3 in October, respectively. Four stages were determined in P. avirostris. In P. tergestina, there were five instars, with males in August and October. The size of parthenogenic females of P. avirostris was 773.4 ± 20.08 μm. In P. tergestina, it was 637.6 ± 49.28 μm. The number of embryos in P. avirostris was 2 to 7, and in P. tergestina, 2 to 8 embryos. The correlations between body length and the number of embryos in both species were statistically significant under the potential model (r > 0.68 for both species, P < 0.001). The transects with the highest abundance were the northern and the southern zones because they are far from the influence of the Jamapa River. The density of these crustaceans is related to optimal temperature, salinity, and dissolved oxygen values. The low proportions obtained from gamogenic individuals of P. avirostris and P. tergestina suggest that in tropical and subtropical regions, gamogenesis is not crucial for the life cycle of these organisms.
A new species of Cincticostella Allen, 1971 (Ephemeroptera, Ephemerellidae) from Yunnan, China and establishment of a new species complex
Authors: Sun Ye-Kang , Yang Rong-Long , Tan Zhi-Wei , Li Xian-Fu , Jacobus Luke M.
Published: July 2024

Cincticostella jianchuansp. nov. from Dali Bai Autonomous Prefecture, Yunnan Province, China, is described based on chorionic structure, nymph, and winged stages. The new species is closely related to C. fusca (Kang & Yang, 1995), but it can be distinguished in the male imago stage by its mesonotum and penes morphology, coloration, and the forking point of the stem of MA+Rs on the forewing; in the nymph stage, it can be distinguished by the length of the posterolateral projections of abdominal segment IX and the setation of the abdominal terga. Compared to other congeners, nymphs and male imagoes of the new species and C. fusca share several morphological characteristics, such as a larger body, mesothorax with medially notched anterolateral projections, forefemur without a subapical band of transverse spines of the nymphs, the area between C, Sc and R1 of the forewings distinctly pigmented, and an apical sclerite on the ventral face of the penes of the male imagoes, supporting the proposition of a new species complex, the jianchuan complex. The systematics of Cincticostella and related genera are discussed briefly.
The Role of Cytokines and T Cells as Mediators of Inflammatory Pathology in Type 1 Diabetes and COVID-19
Authors: Polega James
Published: July 2024

During the coronavirus disease 2019 (COVID-19) pandemic, reports of individuals experiencing new-onset type 1 diabetes (T1D) began to appear in the literature. This spurred subsequent epidemiological studies that demonstrated an increase in new diagnosis of T1D compared to prepandemic. Development of T1D is characterized by the development of an inappropriate T cell response directed against pancreatic beta-cells, leading to eventual loss of insulin secretion. This T cell response occurs in genetically susceptible individuals and may be triggered by viral illnesses. Abnormal cytokine production is another element of the pathogenesis of T1D. Infection with severe acute respiratory syndrome related coronavirus 2 induces a profound increase in the production of inflammatory cytokines and causes significant T-cell dysregulation. These disruptions of the immune system may be linked to the development of T1D following COVID-19.

A third-order numerical method for solving fractional ordinary differential equations
Authors: Yi Xiaopeng , Liu Chongyang , Cheong Huey Tyng , Teo Kok Lay , Wang Song
Published: July 2024

In this paper, we developed a novel numerical method for solving general nonlinear fractional ordinary differential equations (FODEs). First, we transformed the nonlinear FODEs into the equivalent Volterra integral equations. We then developed a time-stepping algorithm for the numerical solution of the Volterra integral equations based on the third-order Taylor expansion for approximating the integrands in the Volterra integral equations on a chosen mesh with the mesh parameter $ h $. This approximation led to implicit nonlinear algebraic equations in the unknowns at each given mesh point, and an iterative algorithm based on Newton's method was developed to solve the resulting implicit equations. A convergence analysis of this numerical scheme showed that the error between the exact solution and numerical solution at each mesh point is $ \mathcal{O}(h^{3}) $, independent of the fractional order. Finally, four numerical examples were solved to verify the theoretical results and demonstrate the effectiveness of the proposed method.
Augmented therapeutic tutoring in diligent image-assisted robotic interventions
Authors: Razek Adel
Published: July 2024

This paper concerns the aptitudes of medical staff to explore new therapies and training exercises for image-assisted robotic diligent interventions. This exploration can be carried out using physical, digital, or both copies of patients. Such physical and digital phantoms should approximate real living tissues through realistic biological properties. Such a realistic assessment could be achieved through strategies to reduce physical and numerical uncertainties. The concept of physical-virtual matched pairs is used in image-assisted robotic interventions to enable such reduction. The present commentary aimed to analyze and illustrate possibilities for increasing the capabilities of medical personnel to explore new therapies and training exercises for image-assisted robotic diligent interventions. In this context, the manuscript focused on the use of the physical-virtual digital twin (DT) concept to monitor image-assisted robotic interventions, thereby reducing the complexity and uncertainties involved in such a procedure. Extensions involve robotic operations assisted by human-in-the-loop DT, artificial intelligence (AI), and augmented reality (AR). The various topics covered in this commentary are supported by a review of the literature.
Instituteurs et institutrices catholiques dans l’enseignement public : la Paroisse universitaire de Franche-Comté (1920-1950)
Authors: Petit Vincent
Published: July 2024

La Paroisse universitaire qui réunit les enseignants catholiques de l’enseignement public a joué un rôle important dans le diocèse de Besançon, terre de chrétienté fervente mais républicaine et patriote. Ses membres ont été à la pointe de l’aggiornamento du monde catholique à partir de 1945, que ce soit avec l’acceptation définitive du principe de laïcité à l’école, le ralliement à des partis de gauche, et sur le terrain spécifiquement religieux, avec la liturgie et l’œcuménisme. Cette étude, au plus près du terrain, s’attachera surtout à reconstituer la formation des groupes d’instituteurs et d’institutrices catholiques au sein de l’enseignement public et leurs relations avec leurs collègues de l’enseignement secondaire et supérieur.
Combined Perspectives on Textile Durability in 18th and 19th-Century Europe
Authors: Fennetaux Ariane , Garcin Emmanuelle
Published: July 2024

Abstract: Cowritten by a historian and a textile conservator-restorer, the article proposes to look at practices of durability as a way of understanding the specific intersection between technology and resources different societies depend on. Using our combined perspectives, we reflect on the particular juncture between resources and techniques which changing practices of durability in Europe between the 18th and the 19th centuries interrogate. The article is based on close reading of written archives as well as first-hand detailed observation of textile artefacts in the study collection of the musée des Arts décoratifs in Paris. Attention to objects shows that despite the advent of the so-called consumer revolution it witnessed, the 18th century remained very much part of the traditional material economy that had prevailed until then in which recycling and textile reuse were ubiquitous across social classes. However, empirical observation of later pieces shows the relationship to durability definitely changing around the second quarter of the 19th century. Whereas pre-industrial societies relied on long-term textile durability embedded in solid, stable fabrics which were integrated into forward-looking assembly techniques and design solutions integrating future “cascades of uses,” the 19th century saw the emergence of more short-sighted assembly solutions in which garments seem to have been made in anticipation they would retain their initial form and shape — whether or not they actually did. The shift, which is hardly visible in written archives, is made manifest in material sources, calling attention to the types of sources we harness to understand the past.
rikawa: Tasmanian Aboriginal Kelp Water Containers
Authors: Leclerc-Caffarel Stéphanie , Sculthorpe Gaye , Rimmer Zoe , Daher Céline
Published: July 2024

Abstract: Water containers made of kelp from lutruwita (Tasmania) are one of the rarest object types found in ethnographic museum collections. Only two, well-documented, historic examples still exist. The British Museum holds one given to it in 1851, after the Great Exhibition of London. An older example, which formed part of the collections of a French naturalist engaged on the d’Entrecasteaux expedition in southern lutruwita in the early 1790s, was located at the musée du quai Branly – Jacques Chirac in 2019, after it had been mislabelled and was thought to be lost for several decades. The technical and cultural information that these two containers evidence is invaluable to Aboriginal people (palawa) in lutruwita today. This paper discusses and reflects on the on-going collaborative research, which involves the Tasmanian Aboriginal community as well as museum scientific staff and curators, in an effort to better understand these rare objects and the once lost techniques they exemplify.
La relique et la réplique
Authors: Guigueno Vincent
Published: July 2024

Résumé : Le point de départ de cet article est un événement contemporain : la célébration en 2019 du centenaire de la marque Citroën, pendant laquelle une « croisière vers l’Ouest » fut organisée, au départ de la place de la Concorde, siège de l’Automobile Club de France. Quatre autochenilles « historiques », ainsi qu’une réplique du Scarabée d’Or réalisée par des étudiants des Arts et Métiers, prirent part à cette parade. Les participants étaient parfois même en tenue d’époque. L’article propose dans un premier temps d’interroger cette mémoire automobile des croisières, réactivée par la marque Citroën et des « passionnés » dans les années 1970 au moment des grands raids annonçant le Paris-Dakar (1978). Il propose ensuite d’étudier les trajectoires patrimoniales des autochenilles conservées dans des collections publiques et privées. Des entretiens ont également été menés avec les auteurs de la réplique du Scarabée d’Or, dont le projet est de refaire le parcours des croisières historiques.
Chandigarh la Main ouverte : d’un urbanisme de plan à un urbanisme de vie
Authors: Chapel Enrico , Mandoul Thierry
Published: July 2024

En contrepoint des interprétations assimilant Chandigarh aux excès de la planification moderne, cette étude interroge les relations que les concepteurs de la ville ont entretenues avec la civilisation indienne ainsi que la place tenue par certaines appropriations des habitants dans l’inflexion du projet urbain initial. L’hypothèse est que le plan d’urbanisme de la nouvelle capitale du Pendjab dessiné par Le Corbusier et ses associés a fait preuve de malléabilité au fil du temps et s’est montré plus susceptible que prévu d’assimiler les pratiques quotidiennes ou occasionnelles de ses habitants. La réception active des habitants offre un nouvel éclairage sur la modernité de Chandigarh. Elle permet d'apporter des nuances aux analyses qui caractérisent ce projet d'urbanisme comme relevant de principes exogènes à la culture indienne.
La valorisation hétérogène des podcasts par les éditeurs de presse
Authors: Lesaunier Marie-Eva
Published: July 2024

Résumé : Cet article s’intéresse à la façon dont quinze médias de presse écrite valorisent leurs podcasts en 2022. Il s’attache à comprendre les modalités de leur mise en valeur sur les sites de presse, fortement hétérogène d’un titre à l’autre, allant de l’existence d’une rubrique dédiée clairement identifiable à une offre diluée dans le reste des contenus mis en ligne. De ce constat ressortent trois principaux résultats : la mise en ligne met en valeur des podcasts représente un savoir-faire spécifique qu’il convient de maîtriser ; une moindre visibilité de l’offre de podcasts sur les sites de presse ne s’explique pas nécessairement par des investissements moindres de la part des rédactions, plutôt, cette forte hétérogénéité est le signe de modalités d’appropriation du podcast par les rédactions de presse écrite en cours de stabilisation, entre conventions ordinaires de la presse en ligne et conventions propres au podcast natif.
Individualisation et autonomisation de la pratique sérielle en France
Authors: Glévarec Hervé , Combes Clément , Cibois Philippe
Published: July 2024

Résumé : La série télévisée est devenue une pratique culturelle de premier plan pour les Français·es. À partir des données de l'enquête Pratiques culturelles en France de 2018 (PC18), cet article examine les pratiques, le goût et la sociabilité de la pratique sérielle. S'appuyant, d'une part, sur un examen des résultats de PC18 et une analyse multivariée des données suivie d'une classification, d'autre part, sur une comparaison avec l'enquête Series 2017 qui lui est contemporaine, il montre l'individualisation de cette pratique culturelle, son autonomisation vis-à-vis de la diffusion télévisée, du téléviseur et même du domicile. L'enquête atteste que la série télévisée est devenue le lieu d'une différenciation sociologique semblable à la musique et caractéristique d'une médiaculture contemporaine et, à un niveau plus fin, d’une individualisation des centres d’intérêt et des préférences.

INTEGRANDO GEOGRAFIAS: PERSPECTIVAS TEÓRICAS E TEMAS HÍBRIDOS NA GEOGRAFIA
Authors: Leles Gabriela
Published: July 2024

O presente artigo tem como objetivo central apresentar e analisar algumas perspectivas teóricas e temas híbridos que se configuram como possibilidades teórico-metodológicas integradas na Geografia. O texto tem como recorte analítico abordagens e temas que entendem a Geografia como uma ciência fragmentada, bipolarizada e dividida entre o polo “humano” e “físico”, e buscam superar essa cisão, concebendo perspectivas integrativas na análise geográfica. Para tal, o presente artigo foi organizado em duas partes: na primeira foram discutidas as dimensões do conceito de “natureza” e as implicações no desenvolvimento de dois domínios de pesquisa na Geografia: a Ecologia Política e a Geografia Física Crítica. Na segunda parte foram apresentados quatro eixos temáticos que podem ser concebidos como possibilidades de trabalho integrado na ciência geográfica, sendo eles: “Patrimônio cultural e natural”, “Justiça ambiental” e “Diversidade social”. Por meio de fundamentações teóricas distintas, verifica-se uma diversidade de possibilidades de trabalho na Geografia que abarcam uma variedade de fenômenos e os analisam considerando a sua dimensão natural e social.
DINÂMICA HIDROLÓGICA, CONECTIVIDADE E VARIABILIDADE DO ÍNDICE DE VEGETAÇÃO (NDVI) NO BAIXO CURSO DO RIO DO PEIXE, OESTE PAULISTA, BRASIL

Published: July 2024

Este trabalho teve como objetivo identificar e analisar a distribuição espacial da cobertura vegetal, através do índice de vegetação, Normalized Difference Vegetation Index (NDVI), em ambientes de planície fluvial do baixo curso do rio do Peixe, baseado na sua dinâmica hidrológica e aspectos de conectividade no sistema rio-planície-fluvial. A área específica de estudos está contida nos domínios dos depósitos aluvionares do baixo curso do rio do Peixe. Nesta área está o Parque Estadual do Rio do Peixe – PERP. Na bacia de drenagem, há intenso uso de pastagens e cana de açúcar. O trecho extremo oeste do rio está alagado pelo reservatório da UHE Porto Primavera (rio Paraná) deste 2001. Para desenvolvimento do trabalho, foram obtidas imagens a partir dos satélites Landsat-5 Landsat 7 e Landsat-8, tratadas através de técnicas de geoprocessamento e tratamento digital de imagens orbitais, utilizando-se um sistema de informação geográfica (SIG). Foram elaborados mapas temáticos a partir da aplicação do NDVI, que auxiliou na interpretação e compreensão da alternância de áreas úmidas e/ou com cobertura vegetal. Foi possível verificar que durante períodos com águas mais altas no rio, a vegetação de maior biomassa ficou mais desenvolvida em detrimento da vegetação de menor biomassa, que tendeu a diminuir após o início de operação da UHE Porto Primavera.

A mobilidade urbana na cidade de Maringá tem enfrentado desafios como congestionamentos, ineficiência do sistema de transporte público, falta de diversificação dos modos de deslocamento, investimento em infraestrutura para veículos, entre outros. Esse quadro ressalta a necessidade de se promover ações voltadas à melhoria do planejamento e à redução do uso do automóvel. A pesquisa é conduzida em três etapas: revisão da literatura, seleção de instrumentos de pesquisa e estudo de caso. A metodologia CDP (Condicionantes, Deficiências e Potencialidades) foi adotada para a análise da estrutura municipal com foco na mobilidade urbana. Buscou-se identificar as condicionantes de funcionamento da modalidade, os problemas a serem resolvidos (deficiências) e recursos a serem aproveitados (potencialidades). Os resultados indicaram que o tempo de espera nos pontos de embarque e desembarque varia de 10 a 40 minutos, com intervalos mais curtos nas linhas de maior demanda; que a idade média dos veículos é de 6 anos e 6 meses e que existem deficiências na infraestrutura dos pontos de ônibus. Constatou-se também que há insegurança em locais de embarque/desembarque, falta de integração tarifária, entre outros. Concluiu-se que o sistema possui, como principais deficiências, a falta de informações, a deterioração dos pontos de ônibus, entre outros aspectos.

ABSTRACT

Aim:

To examine sleep quality and its association with internet usage in undergraduate medical students.

Materials and Methods:

This cross-sectional observational study was conducted among 181 undergraduate medical students from January 2019 to March 2019. A predesigned, pretested, semistructured self-administered questionnaire including information on sociodemographic profiles and lifestyle questions was utilized. The Pittsburgh Sleep Quality Index (PSQI) scale and the Internet Addiction Test (IAT) scale were applied. Statistical analysis was performed using SPSS version 23.0.

Results:

Students with moderate to severe internet addiction showed a total mean score of 6.76 ± 2.45, while those with mild internet addiction had a total mean PSQI score of 6.58 ± 2.57. An increasing severity of internet addiction was associated with poor quality of sleep (22.45%) (P < 0.01). Scores of IAT were assessed in relation to sleep quality, showing that with an increased average total score of internet addiction (39.93 ± 10.36), there was an increasing occurrence of poor sleep quality (P < 0.05). Excessive internet use was linked to poor sleep quality (11.04 ± 1.99) and was statistically significant (P < 0.05).

Conclusion:

Internet usage among young adults has become an alarming public health concern. Practicing caution in its use can help mitigate its negative impacts on both physical and psychological health. Healthy living requires maintaining a balance through participation in sports, education, culture, and other engaging activities.

ABSTRACT

Context:

In contemporary prosthodontics, implant-supported dental prostheses are frequently utilized to restore function and esthetics for individuals who are edentulous. The prosthetic material selection has a big impact on long-term performance and maintenance needs.

Methods:

A retrospective review of patient files from the dental implant clinic of a tertiary care facility was done. Included were patients who had dental prosthesis supported by implants between January 2018 and December 2022. Data were gathered and examined on the prosthesis material, follow-up visits, and maintenance interventions (adjustments, repairs, and replacements).

Results:

Materials for 50 prostheses made of porcelain, 45 prostheses made of acrylic, 35 prostheses made of metal, and 40 prostheses made of composite were assessed. When it came to modifications and repairs, porcelain prosthesis needed less work than acrylic prostheses. Composite prostheses required the least amount of maintenance overall, whereas metal prostheses indicated a considerable demand for maintenance.

Conclusion:

Superior durability is provided by porcelain, frequent repairs are needed for acrylic, structural strength is provided by metal, and composite material gives promising esthetics with low maintenance requirements. These results highlight how crucial it is to take material properties into account when choosing a prosthesis to maximize long-term results and patient happiness.
A constructive proof that many groups with non-torsion $2$-cohomology are not matricially stable

A discrete group is matricially stable if every function from the group to a complex unitary group that is “almost multiplicative” in the point-operator norm topology is “close” to a genuine unitary representation. It follows from a recent result due to Dadarlat that all amenable groups with non-torsion integral

How Do In-Service EFL Teachers Assess Student Language Learning? Analysis of English Assessment Instruments Used in Chilean Secondary Schools
Authors: Tagle Tania , Etchegaray Paulo , Díaz Claudio , Ortiz Mabel , Quintana Marcela , Ramos Lucía
Published: July 2024

The study analyses the assessment instruments designed by Chilean English as a Foreign Language (EFL) in-service teachers. The participants were 110 secondary school teachers from the central, northern, and southern areas of Chile. The data collection technique was document analysis of the assessment instruments designed in their teaching practices. The results suggest that the most typical instrument is a language test, while speaking/writing performance evaluations with rubrics and rating scales are used to a lesser degree, and all having writing, reading, grammar, and vocabulary as their primary assessment foci. It is suggested that universities and administrators of educational institutions promote opportunities for professional updating regarding language assessment. Moreover, pre-service teacher education needs to emphasize and strengthen this didactic dimension.

Investigating Oral Presentation Assessment in LSP: Practices, Demands and Challenges
Authors: Petrović Vesna
Published: July 2024

Giving an oral presentation is a widely used assessment task in higher education, and is very efficient in preparing LSP students for future professional contexts. Empirical studies have made significant contributions to revealing students’ attitudes towards the benefits of oral presentations, but very few studies have investigated LSP teachers’ attitudes regarding the assessment of such presentations. This paper aims to provide deeper insights into LSP teachers’ assessment practices, needs, demands and challenges when evaluating oral presentations. For that purpose, 103 LSP teachers in Serbia and Croatia were asked to indicate the greatest challenges in the assessment process and the most suitable solutions for improving evaluations. The results show that the teachers have difficulty defining the significance level of each rating criterion that describes a student’s performance. In line with this, developing a unique rating scale specifically for LSP oral presentation assessment is recognized as the most helpful strategy in dealing with the challenges they face.

Subtitling has long been the primary type of audiovisual translation in Slovenia. A steady increase in the production of audiovisual content, including English-speaking movies and TV series, along with the development of machine translation, have seen a growing need and opportunity for subtitling globally. The Department of Translation Studies (University of Ljubljana) has offered courses in subtitling to MA students for over twenty years. In the course of this time, teaching methods have been adapted to embrace new technologies. Recently, students have shown interest in incorporating machine translation into the subtitling course. The paper presents an analysis of a subtitling assignment in which students were asked to post-edit DeepL’s Slovene translation of English formatted movie subtitles. The post-edited subtitles were compared with the subtitles done by a group of students from scratch. The results show considerable differences in the students’ multimodal awareness and the overall quality of the subtitles between the two groups.
The Discourse of the “Good Death” in Nineteenth-Century Fiction and a Historical Case Study
Authors: Gadpaille Michelle
Published: July 2024

What people said on their deathbeds preoccupied 19th-century Protestants. Fear of the void after death or of punishment in the afterlife made death terrifying. The process of dying, however, was ritualized to negate these terrors. Having a “good death” constituted reassurance for the dying, comfort for the family, and a lesson for the community. Such comfort was available even from fictional deathbed scenes, where sentiment and imagery softened the harsh reality. This interdisciplinary study explores the similarities between real and fictional deathbed narratives, using a sample of 19th-century novels, two historical deathbeds from Scotland, and a case study of an actual deathbed from the West Indies. The pattern of the good death – in both fiction and biography – includes specific elements such as witness, testimony, requests and advice, music, scripture, and confident hope of Heaven. Some deathbeds even became virtual stages or pulpits, with the dying person at the centre.
Contemporary Anglophone Plays on Montenegrin Stages in the Post-Pandemic Era
Authors: Tripković-Samardžić Vesna
Published: July 2024

This paper explores the reception and impact of nine contemporary Anglophone plays in Montenegro during the post-pandemic era. Analysing data from theatre archives, reviews, and interviews, the study examines the selection, production, and reception of these plays in the context of Montenegro’s political, social, economic, and cultural landscape. The research highlights a sustained interest in both classic and modern-day Anglophone playwrights and delves into complex societal challenges, providing a backdrop for understanding the theatre’s role in addressing these issues. The adapted plays, which explore global concerns and existential themes, contribute to a dialogue with Montenegrin society and challenge accepted norms. The absence of COVID-related plays is discussed, revealing programming policies and priorities. Ultimately, this paper explores how theatre continues to be a vital platform for critique and engagement with contemporary issues, reaffirming its role as a space for dialogue and collective therapy.
Discourse Analysis of Mission Statements of Slovenian Enterprises
Authors: Gaisov Aleksandr , Rižnar Igor
Published: July 2024

The study analyzes the discourse of a sample of mission statements of Slovenian Micro, Small and Medium Enterprises (MSMEs) and large companies across six different industries. First, we assess how distinctive these statements are, both at the level of individual companies and within entire industries, using a custom similarity analysis. Then, through a discourse analysis approach, we examine the methods employed by these companies when creating their mission statements. The results reveal that Slovenian organizations often rely on conservative, company-focused mission statements that place less emphasis on stakeholders. Additionally, despite significant variations among individual statements, there are common themes observed when these statements are grouped by industry.
Assessment-Relevant Stimuli and Judging of Writing Performances – From Micro-Judgments to Macro-Judgments
Authors: Dobrić Nikola
Published: July 2024

The contemporary practice of rating writing performances is grounded in an approach known as judging, which is done to avoid paying conscious attention to discrete elements in texts. Instead, it involves accounting for the overall impression made by a writing performance. However, studies have indicated that while this may be true on a conscious level, the concrete stimuli in texts still preconsciously influence the forming of such overall impressions. What is left largely unnoticed is that most assessment-relevant stimuli require the use of judging to be perceived as such. This implies that an overall, macro-judgment of a writing performance (expressed normally as a score) comprises individual (and largely preconsciously generated) micro-judgments coming together into a complex and non-linear combination-count. The paper presents an argument in favour of such a composition of judgments, demonstrates it empirically by means of a case study, and then discusses the wider consequences of this different perspective on judging.

Iron minerals can significantly impact the performance of soil microbial fuel cells (Soil-MFCs) through extracellular electron transfer (EET). Introducing defects into iron minerals has been shown to reinforce the microbial dissolution process. In this study, oxygen-rich vacancy defects were successfully incorporated into hematite (DHem), resulting in enhanced Soil-MFCs performance. Voltage measurement and Polarization curves demonstrated that the addition of DHem yielded the highest electricity output of 408.96 mV and the highest power density of 324.97 mW/m2. Liquid chromatography revealed that the system with DHem exhibited the most effective phenanthrene degradation at 61.42%, with a 40.70% increase in degradation near cathode areas. The introduction of defects led to increased dissolution of Fe(II) in hematite. The dissolved Fe(II) showed a significant positive correlation with both electricity generation and phenanthrene degradation, confirming that the introduction of defects strengthened the long-distance electron transfer capability by enhancing the dissolution of hematite. In addition, after adding iron minerals, the abundance of Petrimonas, Pseudomonas, Trichococcus, and Azoarcus was increased, which were all important function microorganisms in the system. We concluded that the introduction of defects in hematite can enhance the overall performance of Soil-MFCs by enhance electron transfer and microbial community structure.
When mentally ill women become sexual preys in Zimbabwe: An African indigenous religio-cultural perspective
Authors: Humbe Bernard Pindukai
Published: July 2024

There is a phenomenal increase in the number of cases of women suffering from mental illness in our contemporary society, which is hard hit by pandemics. As scholarship reflects on this condition, there has been little attention paid to the impact of indigenous religion and cultural practices to the sexual and reproductive health of women with mental illness and indigenous entrepreneurs who seek economic fortunes in a post COVID-19 epoch. Largely, the Zimbabwean society detests mental illness and this has rendered mentally ill women to the social margins. However, cases of men from the mainstream society having illicit sexual intercourse with mentally ill women are rampant, both in urban and rural environments. So one can ask why men from the mainstream society are having sexual relations with the ostracised mentally ill women. Prioritizing ethical considerations, this qualitative study uses ritual theory as its theoretical framework, sociology of religion, phenomenology of religion and gendered cultural hermeneutics to explore the prevalence of these sexual practices. Data was gathered through interviews and desk research from January to December 2023. Findings of the study were that these sexual activities are ritualistic, done to enhance success in politics, business, farming and self-initiated churches. An analysis of the reasons behind the performance of these sex rituals showed that a mentally ill woman’s body is an entity which belongs to the spiritual world so the sexual relationship makes it possible for the male entrepreneur to access the spiritual world. Through these rituals, men with entrepreneurial wishes will be attempting to connect with and manipulate the spiritual world. The study concluded that mentally ill women have less choice over their sexual and reproductive lives. They are sexually exploited, yet they lack the capacity to disclose these heinous acts to the mainstream society. They are regarded by the patriarchal society as sexual preys where coercive sex and or rape are used for ritual purposes, with the intent of attaining socio-economic transformation.
