  • Linguistic werk in streamed drag: A translational and translanguaging analysis

    Villanueva-Jordán, Iván (University of Western Sydneys, 2025-01-01)
    In this article, I analyze the inter- and intralingual relationships of two international editions of the Drag Race franchise, Drag Race España and Drag Race México. This study aims to discover how drag is indexicalized through translation and translanguaging strategies and how these strategies reconfigure the representation of local drag culture, subjectivities, and communities in relationship to globally owned formats distributed through streaming. The study follows a qualitative approach. Six episodes of each show were selected following non-probabilistic or purposive criteria. These criteria included (a) having episodes with different structures and (b) gathering dialogues from varied situations and most drag contestants. All the dialogues from the selected episodes were analyzed using a comparative approach. The rationale for this methodology is that contrasting mediatized transnational gendered representations can lead to a better understanding of how symbolic and cultural capital is inserted in television formats to favor their consumption through different distribution technologies, translation, and translanguaging strategies.
  • An Approximation to the Function of Bilingual and Monolingual Editions of Quechua Literature in the Peruvian Publisher Pakarina Ediciones

    Arquíñigo, Diana Nicole Macuri; De La Torre, José Agustín Haya (National University of San Marcos. Faculty of Letters and Human Sciences, 2025-01-01)
    In the Peruvian Literature field, the Quechua literature publication is still a controversial topic because of the hegemonic and canonical Spanish publication predominance. Therefore, this study is focused on the analysis of Pakarina Ediciones’ function; this is a Peruvian publisher that works with indigenous and hegemonic languages. The first specific objective is analyzing the function of bilingual (Spanish-Quechua and Quechua-Spanish) editions, and the second specific objective is analyzing the function of monolingual (Quechua) editions of the referred publisher. Regarding this paradigm, this research discusses the position of a literature that comes from a non-hegemonic language which is also, as a consequence, a non-canonical language in the Peruvian literary system. For that, the publication process and the publisher’s motivations will be specially observed. In order to collect data, semi-structured interviews to the general publisher and authors-translators were made. They provided information about the perspectives and motivations of these participants. This data was analyzed through different theories that belong to the Literature and Translation fields. As findings suggest, it can be noted that both literary editions, bilingual (Spanish-Quechua and Quec-hua-Spanish) and monolingual (Quechua), of Pakarina Ediciones contribute to the development, diffusion, and revindication of Quechua literature; furthermore, they also amplify the hegemonic-canonical Peruvian literary circuit.

    Cardenas, Juan Alonso; Cardenas, Juan Alonso; Mansilla-Lopez, Juan (Springer Science and Business Media Deutschland GmbH, 2025-01-01)
    Vehicular congestion derives from the obstruction of the passage for cars circulating or moving on the roads. In the last five years, Lima has seen an increase in traffic and congestion. One of the solutions to this problem is the improvement of traffic light systems, but in Peru, there have been no studies that address these proposals. For this reason, this paper proposes the design of an intelligent traffic light system using computer vision and artificial intelligence concepts to reduce traffic congestion and its consequences at intersections in the streets of Lima. For the development of the article, an analysis of solutions, technologies and methods used to reduce congestion was carried out. In addition, the design of our proposed solution was carried out, presenting three architecture designs: architecture of components that would make up the system, architecture of integration with Cloud services for our system and an architecture of system layers. Also, the system of detection and time allocation for traffic lights is presented, validating its operation in a test environment, obtaining satisfactory results, such as 85.90% for accuracy, 59.40% for recall and 64.80% of mAP in the detection of the model and a time allocation related to the vehicular flow for the streets that were studied.

    Chaucas, Manuel; Espinoza, Carlos; Castillo-Sequera, Jose Luis; Wong, Lenis (Institute of Electrical and Electronics Engineers Inc., 2025-01-01)
    Insecurity in the Callao (province of Peru) region has intensified in recent years, despite the presence of strategically distributed police stations. This issue is influenced by a lack of integration of advanced technologies in crime prevention, limiting the effectiveness of security strategies. To address this situation, the present study proposes a predictive model based on Machine Learning algorithms applied to the crime context of Callao-Peru. The methodology includes three main stages: Analysis of relevant features, model design, and results validation. In the analysis, eight variables (F1 to F8) associated with criminal patterns were evaluated, while the validation phase compared the performance of the algorithms in terms of accuracy (ACC), precision, F1-score, recall, and AUC. The results show that the Decision Tree algorithm had the highest overall accuracy, achieving an ACC of 0.97, followed by Gradient Boosting (ACC = 0.93) and Random Forest (ACC = 0.92), while K-Nearest Neighbors had the lowest performance (ACC = 0.72). These findings position the Decision Tree as the most effective tool for predicting high-risk crime areas in Callao-Peru.
  • Hydrogeological Modeling in the Archaeological Site Muyu Muyu—Chincheros—Apurímac

    Mogrovejo Gutiérrez, Rubén Esaú; Sarango Julca, Douglas Donal; Contreras Gutiérrez, Efraín Jhiaromir; Gutiérrez, Daniel Minaya; Miranda Gutiérrez, Luis Fernando (Springer Science and Business Media Deutschland GmbH, 2025-01-01)
    Peru is known for its archaeological wealth, ranging from the worldfamous ruins of Machu Picchu to numerous lesser-known but equally significant sites. One such site is the Muyu Muyu archaeological center, located in the district of Uranmarca, Apurímac. Despite its historical and cultural value, Muyu Muyu has not received the attention and care it deserves, leading to conservation issues that threaten its integrity. Among the main challenges this archaeological site faces is the slope inclination caused by soil pressure due to the saturation of the surrounding terrain. The accumulation of water in the soil can lead to an increase in pore pressure, reducing slope stability and increasing the risk of landslides. Solving this problem requires a multidisciplinary approach combining civil engineering, soil mechanics, and hydrogeology. Therefore, the installation of subdrains has been proposed, where 56.7 L per second (l/s) were obtained at the Muyu Muyu site. For this reason, the installation of crown channels is recommended as a preventive and corrective measure to mitigate the negative effects of soil saturation. The subdrains allowed for proper groundwater drainage, thus reducing pore pressure, and improving slope stability. In turn, the crown channels will collect and divert surface water, preventing it from infiltrating the soil and contributing to its saturation.

To address these issues, it is proposed to implement the 5S, SMED, IoT, Cloud Computing and TPM tools. The integration of these tools is validated through a simulation in Arena, considering three scenarios: pessimistic, moderate, and optimistic. The estimated results show significant improvements in each simulated scenario. In the optimistic case, compliance 5S increased from 28% to 80%. Also, the setup time was reduced from 117.92 minutes to 79.96 minutes by applying 5S-SMED. Furthermore, the mean time between failures increased from 29.85 to 38.20 hours (27.97%), because of the implementation of TPM, IoT, and Cloud Computing. Consequently, the initial operational efficiency increases by 14.95%, rising from 64.65% to 79.60%. Therefore, it is concluded that the proposed model enhances the operative efficiency and can be applied to other companies with similar problems and causes.
