Classe, raça, hipocrisia e cordialidade: uma leitura discursiva de essa gente, de chico buarque
Authors: Siqueira Macieira Vitor , Bertocchi Moreira Daniella
Published: December 2024

This article deals with a discursive reading of the novel Essa gente (2019), by Chico Buarque, based on the idea of class prejudice, racial traits, hypocritical discourse and its derivation in the commonsensical discourse of supposed Brazilian cordiality. To this end, we use the epistemological contributions of materialist discourse analysis, especially the concepts of pre-constructed, metaphorical effect (Pêcheux, 2014), irony effect (Orlandi, 2012) and racialized discourse (Modesto, 2021). In parallel, we also turn to Sérgio Buarque de Holanda (1995) and the postulate of the cordial man, as well as the studies on hypocritical discourse developed by Vladimir Safatle (2008). It is possible conclude that the literary discourse of the novel mobilizes a representation of reactionary discursive formations that circulate in the Brazilian society which are reproduced in the novel. The reactionary discursive manifestations show violent, prejudiced and segregationist social dynamics, which are concealed by the hypocritical use of the discourse of cordiality. Additionally, the discussions proposed by Bethania Mariani (2000), Freda Indursky (2012), Jacques Lacan (1998; 2018), Jaime Ginzburg (2015; 2017), Luís Fernando Bulhões (2022; 2024) and Mónica Zoppi-Fontana (2019) are also relevant to this paper.
Os efeitos discursivos no trabalho manual feminino: análise da arte bordada
Authors: Ferreira Cassana Mônica , Mittmann Solange
Published: December 2024

En este artículo presentamos una reflexión sobre los bordados que producen las mujeres, tanto en el hogar como en las artes. Lo hacemos desde una perspectiva discursiva materialista feminista, es decir, en conformidad con principios teóricos del Análisis del Discurso materialista, que se fundamenta en Michel Pêcheux, y en discusiones de la crítica antipatriarcal por autoras feministas. Desde esta perspectiva, planteamos temas como la división social del trabajo, los procesos de significación en el trabajo de cuidados y el efecto del bordado en la producción de obras artísticas que denuncian la violencia. Luego observamos el tránsito del bordado: desde el hogar hacia la calle, de los discursos del espacio privado a los discursos del espacio público, y del campo de la artesanía al campo de las artes. Finalmente, accionamos las nociones de metáfora y metonimia en el abordaje del bordado en obras de Rosana Palazyan. Así, a través del arte bordado, observamos la inscripción en una red antipatriarcal de afiliación de sentidos que marca una posición de resistencia a los saberes dominantes establecidos.
Arte e resistência na obra Trampolim
Authors: Dos Anjos Camila Borges , Mendes Cascaes da Rosa Marilane
Published: December 2024

Racism against Black populations has been a recurring issue in our society over the centuries, dating back to the era of slavery. As a way to confront these violences, Black individuals seek to resist in various forms within the social sphere, often through art. Thus, situated within the territory of French Discourse Analysis, we aim to analyze the racial resistance movements present in the work Trampolim from the Banhistas Collection by Antonio Obá, through the lens of French Discourse Analysis. The work, produced in 2019, revisits an incident that occurred at the Monson Motor Lodge hotel in St. Augustine, Florida, in 1964, when a group of Black individuals who entered the hotel’s pool to protest against a racist practice were subjected to yet another act of violence. By recalling this episode, Obá not only recovers the meanings associated with Blackness—stigma, repression, violence—but also re-signifies them. Through his denunciation of the network of significations that permeates Black populations, he brings forth other possibilities for understanding them through the significant materialities he employs. The meanings are suspended so that new ones may resonate, in a continuous movement, revealing the resistance of the Black subject through art, based on the denunciation of their social condition. Thus, art, resistance, and denunciation intersect, creating a new territory for Black individuals that is polysemic and diverse, harboring meanings that offer alternative ways of understanding them in the discursive scene. The artist's positioning serves a cause, and by occupying a stance within the discourse, he resists others.

The ‘Known Unknown’: Changes in the Media over the Last Quarter Century (2000–2025)
Authors: Aczél Petra , Veszelszki Ágnes
Published: December 2024

Social media, generative AI, fake news and deepfake, influencer communication. Five concepts that have shaped the media landscape and market over the last 25 years. But how do they interact to form a system for describing changes in the media platforms, channels and content? Based on a review of the relevant literature (desktop research), the paper captures and describes four dominant paradigms of change that have emerged over the past quarter century, which have profoundly and irreversibly transformed our everyday practices, habits and attitudes in and through the media. These trends are: 1. changing media messages: the rise of autonomy and virtuality; 2. changing communities and audiences: the rise of personal agency; 3. changing information: the rise of the false; 4. changing representations: the rise of the artificial. The list of four we propose can, of course, be extended and narrowed. However, it is assumed that, by summarising them, we can see more clearly the phenomena and trends that characterise our present and draw conclusions for the future.
A csetbotok felhasználása a magyar nyelv oktatásában
Authors: Dőryné Zábrádi Orsolya , Petzné Tóth Szilvia
Published: December 2024

Napjainkban az oktatás, a tanítás-tanulási folyamat számos változáson megy át. A 21. századi képességek egyre inkább az együttműködés, az önfejlesztés, az élethosszig tartó tanulás fontosságát hangsúlyozzák. Emellett egyre nagyobb teret hódít a mesterséges intelligencia használata az oktatásban. A tanítóképzésben a Magyar nyelv kurzus keretén belül a szemantikai és a grammatikai ismeretek (szófajtan, morfológia, mondattan) oktatását összekötöttük a matematikai ismereteken belül az algoritmikus gondolkodás fejlesztésével, ezzel teret adva a tantárgyak közötti integrációnak és a többszörös intelligencia elméletének. Továbbá a modern technikai vívmányokat felhasználva, átgondolva a hagyományos, frontális, papíralapú oktatást, újraterveztük a SAMR-modell alapján az óráinkat, és a hallgatóknak olyan feladatot adtunk, hogy játsszák el a csetbot szerepét. Ennek a kísérleti kutatásnak, módszertani újításnak a leírását és eredményét foglaljuk össze ebben a tanulmányban.
Profissionalização em Música: uma reflexão a partir das orquestras e dos projetos sociais
Authors: Santos Elisama da Silva Gonçalves , Brasil Anderson , Silva Cícero da
Published: December 2024

Este trabalho tem como objetivo discutir como a literatura aborda a profissionalização em música a partir de projetos sociais e das orquestras. Fundamentada na perspectiva da Educação Musical e na experiência dos autores, são interpostos, no texto, diferentes âmbitos profissionais onde atuam os músicos, com vistas a elucidar de que modo a profissionalização em música é compreendida academicamente no Brasil e como a profissão do músico é percebida dentro da Educação Musical enquanto área autônoma de conhecimento. O artigo aborda também pesquisas que tratam especificamente sobre a atuação de educadores musicais em comunidades e o desenvolvimento profissional de jovens a partir da vivência com práticas musicais em projetos sociais (SANTOS, 2014; BRASIL, 2014). Os resultados apresentados corroboram que os projetos sociais são fundamentais para promover a formação e a profissionalização em música de jovens oriundos, sobretudo de comunidades marginalizadas e que, em conformação com as pesquisas apresentadas, além de capacitá-los em música, esses espaços podem promover a autonomia dos sujeitos e a inserção socioprofissional desses atores.

Antigos marcadores sociais, novas abordagens políticas
Authors: Lopes da Costa Andréa , de Campos Gomes Edlaine
Published: December 2024

The themes of gender, sexuality, race, ethnicity and religion, often referred to as identity issues, emerged in the public debate of Western countries in the second half of the 20th century; since then, they have been surrounded by controversy. This emergence is the result of the collective action of social movements that invested in dialogue (not always peaceful) with the State in search of a resolution to their demands for recognition and for social and political rights. Thus, second-wave feminist movements were successful in redefining the relationship between the public and private spheres, denouncing that the relationships produced in the private sphere had strong contours of a political project. In turn, civil rights movements presented forms of pressure to combat racial inequalities and to create fair legislation. The LGBTQIAP+ movements gained visibility from the 1980s onwards in the context of the fight for social rights and respect for expressions of sexuality. However, this emergence in a political debate in the second half of the 20th century led one to believe that they were recent issues. In fact, they are historical social markers and fundamental for understanding social relations. Furthermore, as defended by counter-hegemonic perspectives such as intersectional studies, postcolonial and decolonial analyses, these are not merely themes, but rather organizing elements of the world. They objectively configure social relations by establishing hierarchies of power, domination and prestige; and, in the same way, they organize work, education and other elements of quality of life, defining access and exclusion. Thus, it is not possible to read the world without considering them.
Study of acute toxicity of the biomass of Cladophora sp. and phycocyanin for Daphnia magna
Authors: Hudz Nataliia , Turkina Vira , Kobylinska Lesya , Mykitchak Taras , Savickienė Nijolė
Published: December 2024

In the current economic conditions, an active search is conducted for cost-effective and well-balanced feeds and feed mixtures for fish farming. The development of functional feeds using biomass of wild algae is becoming a central focus in the fish feed production. Although these supplements offer a promising path to sustainable and environmentally friendly fish feeding, their impact on the ecosystem requires detailed research. The aim of the study was to determine the acute response of Daphnia magna to the influence of new feed products derived from the wild algae of the Baltic Sea, phycocyanin on its own, and their binary mixture. The study was conducted using the standard aquatic toxicology method. To establish the 48-hour LC50, the probit analysis method was used. The results showed that D. magna is more sensitive to the effects of phycocyanin, with the following order of toxicity: phycocyanin > the mixture (1:1) > the biomass of Cladophora sp. The median lethal concentrations at 48 h were 100 mg/l, 920 mg/l, and 1720 mg/l, respectively. The obtained data allows to refer the tested compounds to low-hazard substances according to the Globally Harmonized System (GHS). The observed effects were compared with the effects of the mixture noticed in the toxic units (TU) model. In 48 hours, the mixture of the dry biomass of Cladophora sp. and phycocyanin at a ratio of 1:1 exhibited synergism. The obtained results will allow choosing the optimal ratio of the raw materials used in fish feeds without inflicting harm to the aquatic ecosystem and loss of their nutritional value.
Spatial and seasonal variations in physico-chemical parameters and the water quality index at the Okhuaihe River in Ikpe Community, Edo State, Nigeria
Authors: Odigie Omorede , Elimhingbovo Isaiah
Published: December 2024

The scarcity of clean water in rural Nigerian communities leads to dependence on streams and rivers which are often polluted by domestic and industrial activities distorting the quality of water. Freshwater ecosystems, which are important for global biodiversity, are constantly burdened with threats from environmental changes as well as human misuse. This study was aimed at investigating the spatial and temporal variations of physico-chemical parameters and the water quality index (WQI) of the Okhuaihe River in Ikpe, Edo state, Nigeria, used for different domestic activities. The study assessed parameters like air and water temperature, pH, electrical conductivity, flow rate, total dissolved solids, phosphate, chloride, iron, zinc, and manganese at four stations over a six-month period. Samples such as air and water temperature and pH were collected and measured in situ, while others were collected using polyethylene bottles and a 250 ml amber bottle for biochemical oxygen demand (BOD5). Results indicated that while some physico-chemical parameters like the width, the flow rate, and phosphate showed considerable differences, most did not differ significantly. Temporally, there were significant seasonal variations in air temperature, electrical conductivity, total dissolved solids, chloride, iron, zinc, and manganese. The WQI calculations showed that the water quality at all stations was within safe limits for human consumption and supported aquatic life. Despite some fluctuations due to seasonal changes and anthropogenic activities, the overall quality remained suitable for domestic use. This underscores the importance of constant monitoring and management of water resources to allay pollution and ensure sustainable water supply in rural communities.
ESTRATEGIAS DE GESTIÓN FORESTALY CAMBIO CLIMÁTICO: UNA REVISIÓN
Authors: Martínez-Sánchez Julio Nemorio , Himmelsbach Wibke , Yáñez Díaz María Inés , González-Tagle Marco , Garate Escamilla Homero Alejandro
Published: December 2024

El cambio climático (CC) es un fenómeno global que tiene diversas repercusiones en la distribución, biodiversidad y productividad de los ecosistemas forestales. Los bosques son una parte fundamental del sistema climático y un componente clave en las estrategias de adaptación y mitigación. Los impactos del CC en los bosques han dado lugar a la gestión forestal adaptativa (AFM) con el fin de integrar los cambios en la variabilidad climática actual y futura como uno de los componentes más importantes de la gestión forestal. La AFM puede dividirse en estrategias de resistencia, resiliencia y transición. La AFM debe seguir evolucionando a medida que los impactos del CC en los bosques aumentan en intensidad y frecuencia para hacer frente a los requisitos medioambientales, sociales y económicos de las generaciones futuras. El éxito de la aplicación de la gestión forestal en el contexto del CC, incluida la migración asistida, dependerá en gran medida de su aprobación a nivel científico, social, político y económico. A medida que el cambio climático se intensifique, se espera que este conjunto de estrategias acelere los cambios en la distribución y composición de los bosques necesarios para el desarrollo de individuos, especies y ecosistemas con mayor capacidad de adaptación.
A mathematical model for population distribution II: Linear systems
Authors:   Democritus University of Thrace, Greece, Elias Nicholas
Published: December 2024

The present paper constitutes a continuation of a previous relevant paper, entitled “A mathematical model for population distribution” by Elias (2023), in which the general theoretical model was described, and some initial applications were presented, namely some approximations of population distribution of a one-dimensional inertial system and a special case of one-dimensional dynamic system. Herein, by using the above model, the following issues will be addressed: a) the examination of multidimensional linear systems, both inertial and dynamic, facilitating the study of polycentric cities and systems of multiple cities (metropolitan areas) and b) the variation of the population distribution due to the geographical diversifications of the habitat of the system, as in a sloped terrain or of coastal cities. For each of the above cases, their behaviour is presented by producing and analysing the corresponding equations of motion and distribution and, whenever possible, an effort has been made to qualitatively compare the theoretical results to field data.

Tarihte Savaş Arabaları ve Şehnâme’deki Bir Tasviri
Authors: İkibeş Samet
Published: December 2024

At arabaları insanoğlu tarafından tarih boyunca çeşitli amaçlarla kullanılmış ve savaş arabaları bu amaçlardan birini teşkil etmiştir. Lakin Bronz Çağı zarfında askerî hususta görev almaya başlamışlardır. Zamanla da orduların temelini meydana getirmeleri ile birlikte, birçok medeniyette izlerine rastlanabilmiştir. Bu çalışmada savaş arabası kullanan tüm medeniyetleri incelemek mümkün olmadığından Eski Mısır, Hitit, Myken, Eski Yunan, Pers, Roma, Eski Çin ve Eski Türk gibi uygarlıklar üzerinde durulmuştur. Çalışmanın temel amacı savaş arabalarının gelişimini Prehistorik Çağlardan Orta Çağ’a kadar incelemektir. İkincil bir amaç da Şehnâme’deki tasvirlerini minyatür sanatı çerçevesinde gözden geçirmektir. Savaş arabalarına sahip olan medeniyetler kendi coğrafî koşulları ve savaş taktik-stratejilerine göre makinelerini tasarlamışlardır. Ancak herhangi bir savaş arabası aks, tekerlek, sepet, direk, boyunduruk ve bağlantı bölümleri gibi ortak tamamlayıcı unsurlar barındırmak zorundaydı.

Savaş aracını meydana getiren bu parçaların aynı zamanda farklı görevleri de bulunurdu. Bu araçlar muharebelerde genellikle piyadelerin saflarını dağıtmak amaçlı kullanılmıştır. Arabalar Bronz Çağı boyunca piyadeleri dağıtma noktasında önemli yararlar sağlamalarına karşın zamanla saf dışı kalmaya başlamışlardır. Nitekim işaret edilen durumun en büyük sebebi, süvari birliklerinin ortaya çıkmasıdır. Süvariler savaş arabalarına kıyasla daha hızlı ve kullanışlı oldukları için önem kazanmışlardır. Fakat bu çerçevede araçların Eski Çağ ve Orta Çağ boyunca tamamen ortadan kalktığı da düşünülmemelidir. Şehnâme İran’ın milli kahramanlık destanlarından biri olup hem tarihî hemde mitolojik konuları aktarmaktadır. Ek olarak İsfendiyâr ile Simurg mücadelesinde dikenli bir savaş arabası da yer almaktadır. Bu hikâyede İsfendiyâr, arabasının üzerindeki dikenler yardımıyla Simurg’un canını almış ve belirtilen mücadele birçok minyatürde tasvir edilmiştir.

Konsep Terms Of Trade dan Dampaknya Terhadap Ekonomi Suatu Negara
Authors: Arinda Ramadani  , Yuyun Eva Elviana  , Mohammad Khafid Mudlofar  , Sarpini
Published: December 2024

Terms of Trade (ToT) is a crucial indicator in international trade that illustrates the ratio between a country's export prices and import prices. This concept provides an overview of a country's purchasing power in the global market and reflects the relative benefits gained from trade. An increase in ToT indicates enhanced purchasing power, leading to benefits such as trade surpluses, strengthened currency value, and economic growth. Conversely, a decline in ToT negatively impacts a country, causing inflation, trade deficits, and weakened public purchasing power. Factors such as global commodity price fluctuations, exchange rates, export-import demand, and trade policies significantly influence ToT. This study highlights the importance of understanding ToT as a strategic tool in formulating trade and economic policies, especially for countries reliant on commodity exports. With proper understanding, countries can mitigate the adverse effects of ToT fluctuations and enhance societal welfare through adaptive and responsive policies.

Dental magnetic resonance imaging (MRI) has long been perceived as overly complex, costly, and limited in availability. Despite the numerous advantages of this radiation-free, non-invasive procedure for soft tissue diagnostics in the head and neck region, its imaging capabilities for hard tissue, such as bones and teeth, have thus far remained limited in comparison to conventional X-ray technology. In recent years, however, technological advances have led to a notable enhancement in the image quality and the range of applications of dental MRI. This article presents a comprehensive review of the current literature on the utilization of dental MRI for dentomaxillofacial conditions. The article focusses on novel MRI protocols that have been specifically developed to address the inherent challenges associated with imaging the head and neck region. It also considers the latest technological advances, including innovative coils and the use of low and high-field MR systems. The practical case studies are from the fields of conservative dentistry, prosthodontics, orthodontics, oral surgery, and maxillofacial surgery, demonstrating the theoretical concepts and emphasizing the clinical advantages of dental MRI. In conclusion, dental MRI can be a valuable complement to and, in certain cases, a true alternative to X-ray-based procedures.
Evaluating the Environmental and Economic Impacts of MARPOL Compliance in the Global Shipping Industry
Authors: Riadh Mohammed
Published: December 2024

The International Convention for the Prevention of Pollution from Ships (MARPOL) serves as a critical regulatory framework aimed at mitigating marine pollution caused by shipping activities. This study systematically evaluates the environmental and economic impacts of MARPOL compliance within the global shipping industry, focusing on its effectiveness in reducing pollution and enhancing sustainability. Utilizing a mixed-methods approach, we collected and analyzed quantitative data from a diverse sample of 50 shipping companies, alongside qualitative insights from industry experts and environmental reports. Our findings indicate a significant correlation between MARPOL compliance and a reduction in key environmental indicators, including a 30% decrease in oil spills and a 25% reduction in greenhouse gas emissions over the past decade. Moreover, while the initial compliance costs—averaging a 15% increase in operational expenses—pose challenges, the long-term economic benefits, such as a 20% increase in operational efficiency and enhanced market competitiveness, are noteworthy. The study underscores the necessity for ongoing regulatory support and financial incentives to facilitate compliance, particularly for smaller operators. Additionally, the research highlights the importance of continuous monitoring and adaptation of MARPOL regulations to address emerging environmental challenges, including the impacts of climate change. Ultimately, this study provides a comprehensive understanding of the dual impact of MARPOL compliance, presenting valuable insights for policymakers, industry stakeholders, and researchers aiming to foster a more sustainable shipping industry.

This study provides a comprehensive analysis of Port Reception Facilities (PRFs) and their critical role in supporting compliance with MARPOL Annex V within the maritime industry from 2018 to 2023. The research employs a mixed-methods approach, integrating quantitative data on PRF operations with qualitative insights from stakeholder engagement. Key findings reveal significant advancements in environmental performance, including a 95% reduction in water pollutants, a 40% decrease in greenhouse gas emissions, and a 60% increase in solid waste recycling efficiency. The implementation of PRFs has achieved a compliance rate of 92% with MARPOL regulations and 88% with ISO standards. Furthermore, the study highlights a 30% increase in aquatic biodiversity and a 70% reduction in landfill volume associated with improved waste management practices. The integration of digital technologies has notably enhanced stakeholder engagement rates from 55% to 80%. Despite these positive outcomes, critical areas for future development are identified, including the need for continued investment in green technology, international standardization, and capacity building. These findings offer valuable insights for policymakers, port authorities, and industry stakeholders, contributing significantly to the existing literature on maritime environmental protection and sustainable port waste management strategies.
Legal and Environmental Implications of Shipwrecks under MARPOL and UNCLOS
Authors: Kadhafi Muammar
Published: December 2024

This study examines global shipwreck management practices and their environmental implications through analysis of 762 significant cases from 45 maritime nations during 2000-2020. Using a mixed-method approach combining quantitative environmental impact data with qualitative assessment of response mechanisms, we investigated the effectiveness of technological solutions and international cooperation frameworks. Key findings reveal that the Asia-Pacific region accounts for the highest concentration of incidents (32.2%), with advanced technology implementation showing significant improvement in management outcomes (92% success rate for ROV surveys). Bilateral response mechanisms demonstrated superior efficiency with reduced response times (2.8 days average) and higher success rates (92%) compared to unilateral efforts. Strong correlation between technological adoption and environmental recovery rates (r=0.85, p<0.001) indicates the importance of modernizing management approaches. Analysis shows a positive trend in reducing environmental impact, with oil spill volumes decreasing from 45,200 tons in 2000 to 22,100 tons in 2020. These findings suggest the need for enhanced international cooperation, standardized technological implementation, and region-specific management strategies to improve global shipwreck response effectiveness. The study provides evidence-based recommendations for policymakers and maritime authorities to strengthen existing frameworks and adopt more efficient management practices.

Authors: Chairunnisa Andi Sitti
Published: December 2024

This research investigates the legal and practical dimensions of Port State Control (PSC) inspections as mandated by the International Convention for the Prevention of Pollution from Ships (MARPOL). Utilizing a qualitative methodology, the study integrates comprehensive document analysis, semi-structured interviews with maritime stakeholders, and illustrative case studies to evaluate the efficacy of PSC inspections in ensuring regulatory compliance and environmental protection. The findings indicate a relatively stable compliance rate of 94.1% to 95.7% over a five-year period, with recurring deficiencies primarily identified in Oil Record Book discrepancies and sewage treatment systems. Significant regional variations were observed, wherein European ports demonstrated stricter enforcement mechanisms compared to those in other regions, highlighting disparities in global implementation practices. Challenges such as resource constraints, inconsistent inspector training, and limited collaboration between port states and flag states were identified as critical barriers to effective enforcement. The study emphasizes the necessity of targeted training programs, enhanced inter-regional cooperation, and the integration of advanced technologies to improve inspection processes and foster a uniform enforcement regime. These findings contribute to the discourse on maritime governance by offering evidence-based recommendations for policymakers and regulatory bodies aimed at strengthening the effectiveness of PSC inspections and advancing marine environmental protection.

The theory of full non-rigid molecular groups (f.NRG) proves useful in exploring the internal dynamics of these molecules. In this study, we determined the group order of Cyclopentane and identified its conjugacy classes. Using computational methods, we calculated the group order, its character table, conjugacy classes and the point group of Cyclopentane was analyzed.  Our results showed that the point groups were found to be isomorphic to the Wreath Product 〖 Z〗_5 wrZ_2, where Z_n represents a cyclic group of size n, with order 160 and 16 conjugacy classes. All calculations were performed using GAP 4.11.1.

Contagious Bovine Pleuropneumonia (CBPP) is a highly infectious disease that poses a significant threat to cattle populations, particularly in sub-Saharan Africa, where livestock is a critical economic and food security resource. Early detection and intervention are essential to mitigate its impact on cattle productivity and rural livelihoods. This study aims to develop a predictive model for CBPP using the Random Forest (RF) algorithm, a robust and scalable machine learning technique renowned for its accuracy and ability to handle complex datasets. The research utilized a dataset of 847 samples collected from veterinary clinics in Yola, Adamawa State, and online sources. Key symptoms of CBPP, such as respiratory distress, nasal discharge, fever, and pleuritis, served as input features for the model. Preprocessing steps, including outlier detection, handling missing values, and data normalization, were applied to ensure the dataset's quality and reliability. The RF algorithm was trained and validated to classify CBPP cases effectively, with performance metrics such as accuracy, precision, recall, and specificity used to evaluate its effectiveness. The experimental results demonstrated an impressive prediction accuracy of 95.65%. Results demonstrated the RF model's high accuracy and robustness in predicting CBPP, offering a practical tool for early diagnosis and decision-making. The study further highlights the potential of deploying the model in a mobile application, enabling cattle breeders to perform preliminary diagnoses and seek timely veterinary intervention. This approach aligns with global efforts to integrate technology into agricultural practices, enhancing livestock disease management and supporting sustainable agricultural development. The findings contribute to the growing body of knowledge on applying machine learning to livestock disease prediction, showcasing Random Forest's potential to transform disease management strategies in the livestock sector.
Direct Observation Teaching Shifts (DOTS): An Approach to Using 360-degree Assessments
Authors: Molins Caroline , Martinez Martinez Carmen J
Published: December 2024

Objective

Multisource feedback or 360-degree assessments are known to be a reliable and feasible evaluation tool that can have profound effects on residents. Direct observation of resident’s patient encounters is a useful educational instrument that provides information about a resident’s strengths and weaknesses but can be costly and difficult to implement on a regular basis. In order to facilitate the 360-degree assessments and enhance resident education, direct observation teaching shifts (DOTS) were created. DOTS were defined as scheduled shifts in which paired faculty/residents were assigned a chief complaint based patient encounter and the 360-degree assessment was used as the evaluation tool. The purpose of this innovation was to assess the resident’s perceptions and number of timely completed 360 evaluations after the introduction of DOTS.

Methods

Using the American Board of Emergency Medicine Model of Practice of 2016, signs, symptoms and presentations that were identified as “critical” were matched to reference textbook chapters for reading and studying purposes. Each 4 week block was assigned two distinct topics. Over a 12-week period, residents that were scheduled to the EM rotation were assigned DOTS paired with a designated faculty member, who received faculty development on DOTS and feedback. All residents had the opportunity to have at least 1 DOTS. At the completion of the 12-week period, residents and faculty were surveyed using Microsoft Forms and data was extracted and analyzed using Microsoft Excel.

Results

After completing the 12-week period, the number of 360 evaluations more than tripled per week. Most of the residents that were scheduled a DOTS completed a 360 evaluation (67%) and felt that they received individualized learning (83%) from the attending. In conclusion, the majority (75%) said that they would like to continue to be scheduled DOTS.

All the attendings involved in DOTS believe that we should continue completing the DOTS and involve more attendings.

Conclusion

With the implementation of DOTS, there was a three-fold increase in 360-degree assessments completed, and the resident’s perceived that it was educationally beneficial to them.
