Abstract. Reliable short-term sea ice forecasts are needed to support maritime operations in polar regions. While sea ice forecasts produced by physically based models still have limited accuracy, statistical post-processing techniques can be applied to reduce forecast errors. In this study, post-processing methods based on supervised machine learning have been developed for improving the skill of sea ice concentration forecasts from the TOPAZ4 prediction system for lead times from 1 to 10 d. The deep learning models use predictors from TOPAZ4 sea ice forecasts, weather forecasts, and sea ice concentration observations. Predicting the sea ice concentration for the next 10 d takes about 4 min (including data preparation), which is reasonable in an operational context. On average, the forecasts from the deep learning models have a root mean square error 41 % lower than TOPAZ4 forecasts and 29 % lower than forecasts based on persistence of sea ice concentration observations. They also significantly improve the forecasts for the location of the ice edges, with similar improvements as for the root mean square error. Furthermore, the impact of different types of predictors (observations, sea ice, and weather forecasts) on the predictions has been evaluated. Sea ice observations are the most important type of predictors, and the weather forecasts have a much stronger impact on the predictions than sea ice forecasts.

CRIMINOLOGICAL DESCRIPTION OF DOMESTIC VIOLENCE AGAINST WOMEN OF KAZAKHSTAN
Authors: Abdukarimova Zauresh Turganbayevna , Abdramanova Nazira Kaiypbekkyzy , Kainazarova Makpal Bakhytzhanovna
Published: April 2024

This article is based on a normative and statistical analysis of domestic violence against women in Kazakhstan. Special attention is paid to the factors and obstacles faced by the State in solving the problems of preventing domestic violence against women. Today's reality is that various types of violence are used against women due to various factors. At the same time, recent studies show the lack of a unified approach to the causes of domestic violence against women. The criminal legal protection of women from domestic violence is connected with the authorities and is built through the solution of three tasks: tougher penalties for domestic violence against women; strengthening of specialized police units; revision of approaches to the organization of work with victims. The study is based on existing developments, awareness of facts and experience in the field of countering domestic violence against women at the national, regional and global levels. The results show that special attention has been paid to the issues of countering domestic violence in the Republic of Kazakhstan in the last decade. There is a strong presence of civil society, NGOs and civil activists involved in this process in the country, using various approaches to the problem of protecting women from domestic violence, including information and dialogue with the public. However, the analysis of existing methods of protecting women from manifestations of domestic violence in the Republic of Kazakhstan has shown the need to develop more advanced forms, methods and measures to prevent domestic violence against women for their use by law enforcement, government agencies, as well as civil society institutions, to develop clearer criteria for distinguishing crimes on family and domestic grounds from the bulk of crimes.
MEDIATION IN CRIMINAL PROCEEDINGS AS A SPECIAL MECHANISM FOR CONFLICT RESOLUTION
Authors: Diachuk Marianna Ivanovna , Ramazanova Ainur Serikhanovna
Published: April 2024

In modern Kazakhstan judicial proceedings of civil and criminal cases is the primary mode of protecting constitutional rights and freedom. These days conflicting parties are becoming increasingly interested in settling disputes on a mutually advantageous basis on their own, while exercising control over the procedure and its result. Today, considerable attention has been paid to the problems of conciliation. The importance of the out-of-court settlement of legal disputes has been emphasized for several years by the leaders of the highest organs of State power in Kazakhstan. Also, there is some positive experience in introducing conciliation procedures through a mediator in the legal system of countries. In many developed countries, mediation exists and is used as a specific form of dispute settlement in conjunction with judicial proceedings. However, introducing the best practices of conflict settlement remains little studied in Kazakh jurisprudence. Currently, mediation is becoming an increasing well-know and widespread method of mediation in conflicts. In both civil and criminal cases and material, the resolution of the conflict between the parties through mediation procedures is increasingly finding its application. One of the main goals of mediation is to reduce conflict in society, be achieved through consolation procedures. The mediation procedure is reflected in the basic principle of the criminal process – the adversarial nature and equality of the parties. The suspect, the accused, the defendant can freely deny their quilt or plead guilty, reconcile with the victim, conclude a procedural agreement, an agreement to achieve reconciliation through mediation…
CONSTITUTIONALITY OF THE INSTITUTION OF CRIMINAL PROCEDURAL PREJUDICE
Authors: Ismagulov Kairat Eslyamkalievich , Kaliakperova Elena Nikolaevna , Eskendirov Asan Kairullovich
Published: April 2024

The authors considered the institution of criminal procedural prejudice and its compliance with the Constitution of the Republic of Kazakhstan, as it has a multidimensional holistic nature, arising in order to establish the circumstances to be proved in criminal proceedings. The study reveals the role, place and content of prejudice in criminal proceedings in Kazakhstan based on the study of law enforcement practice and analysis of legislation of foreign countries. Some problematic situations arising from the application of prejudice in criminal proceedings, as well as issues of implementation of new regulations on prejudice in criminal proceedings, are considered. The authors recognize prejudice as an established means of solving problems arising in the judicial and investigative practice in the legal field. It is noted that despite the noticeable influence of Russian criminal procedure science and legislation on the formation of this institution in Kazakhstan, the domestic legislator and the scientific community maintain a conservative attitude to the institution of prejudice. During the period of active formation of national legislation, the problem of harmoniously designed procedural institutions should not remain unresolved, especially if they contribute to the most effective administration of justice. Recognizing prejudice as a large and in many respects complex theoretical and applied problem of the science of Kazakhstan criminal procedure law, which still remains poorly developed and therefore in need of thorough and comprehensive research. Interestingly, the topic of prejudice is still not included in university law curricula, but in textbooks on criminal procedure (criminal procedure law) it is rarely affected. In the criminal procedure norm itself, which enshrines prejudice, the legislator has not established clear mechanisms for its implementation, and therefore, the authors propose options for harmonizing criminal procedure law, as well as adjusting the provisions of criminal procedure legislation on prejudice, as part of the institute of evidence, taking into account advanced foreign experience.
Palestina: Manual da ocupação
Authors: Caramuru Teles Bárbara
Published: April 2024

Este livro foi pensado como um pequeno manual da ocupação da Palestina, acessível e didático. Portanto, aqui, darei ênfase nos acontecimentos que nos permitem compreender a situação colonial na Palestina, bem como o longo processo de limpeza étnica e expulsão dos palestinos iniciado ainda nas primeiras décadas do século XX. Tal projeto é um desdobramento de uma política de ocupação da terra e expropriação da população autóctone, o sionismo moderno. Na linha de uma análise pós-colonialista e decolonialista, compreendo o processo violento de ocupação deste território e dos corpos palestinos como fruto deste projeto colonial. Portanto, neste breve manual elucidarei a conformação do sionismo moderno, bem como o início da ocupação da terra palestina, passando pelas diferentes estratégias adotadas para a tomada de terras, a catástrofe e expulsão dos palestinos, com ênfase nos anos de 1948 e 1967 e as sucessivas escaladas de violência e expansão colonial que chegam até a atualidade.

The Work of Art as a Fictionalized Duplicate of Life: Boris Lehman's Babel film project in the Light of Marcel Proust's In Search of Lost Time
Authors: G. Peydró Guillermo
Published: April 2024

Belgian filmmaker Boris Lehman has created what is surely the most ambitious film diary in the history of cinema, Babel, a twenty-four-hour film divided into nine parts and several appendices, which traces a sort of sublimated filmic duplicate of the author's life between 1983 and 2020. In Babel, Lehman painstakingly records the daily activities of his life: eating breakfast, walking, talking with friends, traveling, playing the piano, being evicted, looking for a job or paying his taxes. Despite the appearance of a realistic duplicate, the filmmaker claims for his film the denomination of "autobiographical fiction". How can we understand this mismatch between the everyday reality suggested by the film and the fictional will that the author proposes as a key to reading it? This article proposes to consider this fictional quality of Lehman's autobiographical project in the light of the aesthetic proposal crystallized in Marcel Proust's novel In Search of Lost Time, which Gérard Genette proposed to call "autofiction".

Authors: Łukomska-Szarek Justyna , Wójcik-Mazur Agnieszka , Martynko Anna
Published: April 2024

The idea of the present paper was to assess budget management in local government units in Poland in 2019-2021 using multi-criteria analysis methods. The evaluation was broken down by different types of LGUs using the TOPSIS method based on min-max normalization. The survey was conducted using secondary data obtained from the Ministry of Finance website, broken down by budget (per capita) and debt indicators. For all LGUs in total, the best position in 2019-2021 was found in voivodeships, whose ranking remained unchanged despite the COVID-19 pandemic. An analogous situation was observed in rural municipalities. The last position in the ranking was occupied by towns with powiat status (2019) and metropolitan areas (2020-2021). Between 2019 and 2021, the number of entities placed in financial condition class 2 was increasing only in towns with powiat status. A reduction in financial condition (in Class 2) was also evident in rural municipalities, in powiats, and metropolitan areas. Over the years 2019-2021, there was a reduction in the number of entities with financial condition class 3 in rural municipalities and towns with powiat status. The leaders in benchmarking in rural communes were Kleszczów and Godkowo; urban-rural communes: Kamieńśk and Lubniewice; urban communes: Krynica Morska and Hel; cities with county rights: Sopot and Świnoujście, metropolises: Katowice and Warsaw, voivodeships: Pomeranian and Greater Poland. The powiats were characterized by great diversity, the best places in the ranking in individual years went to the Wolsztyński, Sztumski and Golubsko-Dobrzański powiats.
A feature transfer model with Mixup and contrastive loss in domain generalization

Published: April 2024

When domains, which represent underlying data distributions, differ between training and test datasets, traditional deep neural networks suffer from a substantial drop in their performance. Domain generalization methods aim to boost generalizability on an unseen target domain by using only training data from source domains. Mainstream domain generalization algorithms usually make modifications on some popular feature extraction networks such as ResNet, or add more complex parameter modules after the feature extraction networks. Popular feature extraction networks are usually well pre-trained on large-scale datasets, so they have strong feature extraction abilities, while modifications can weaken such abilities. Adding more complex parameter modules results in a deeper network and is much more computationally demanding. In this paper, we propose a novel feature transfer model based on popular feature extraction networks in domain generalization, without making any changes or adding any module. The generalizability of this feature transfer model is boosted by incorporating a contrastive loss and a data augmentation strategy (i.e., Mixup), and a new sample selection strategy is proposed to coordinate Mixup and contrastive loss. Experiments on the benchmarks PACS and Domainnet demonstrate the superiority of our proposed method against conventional domain generalization methods.

La necesidad de una gestión hídrica efectiva se vuelve más apremiante en un escenario donde el agua disponible para el consumo humano y la producción constituye una fracción mínima del agua dulce total en el planeta. A medida que el consumo de agua dulce continúa en aumento y los ecosistemas acuáticos se ven amenazados, se vuelve imperativo adoptar enfoques más informados y tecnológicamente avanzados para garantizar la sostenibilidad del recurso (Kumar et al., 2020; Mekonnen & Hoekstra, 2016) . En este contexto, la gestión eficiente de los recursos hídricos requiere herramientas que permitan comprender y modelar los procesos hidrológicos a nivel local y detallado. Los modelos hidrológicos hiper-locales emergen como una respuesta prometedora para analizar comportamientos específicos en áreas determinadas, superando las limitaciones de los modelos a gran escala (Beven & Cloke, 2012; Bierkens, 2015). Estos modelos, que consideran características específicas como topografía, vegetación y condiciones climáticas locales, proporcionan una visión detallada que puede informar decisiones más precisas y contextualizadas en la gestión del agua. Sin embargo, la implementación efectiva de estos modelos enfrenta un desafío crucial; la disponibilidad y calidad de los datos hidrológicos necesarios para modelamiento. La gestión eficiente de los recursos hídricos en un mundo en cambio requiere un marco integral que combine el conocimiento tradicional con las herramientas tecnológicas más avanzadas. Los modelos hidrológicos hiper-local y los principios FAIR ofrecen directrices clave para superar los desafíos actuales en la gestión del agua, permitiendo una comprensión más detallada y una toma de decisiones informada. La colaboración entre la ciencia, la tecnología y la gobernanza es esencial para garantizar la disponibilidad y sostenibilidad del recurso hídrico en un futuro incierto

Published: April 2024

In this work, we investigate the expenditure behavior of Chilean municipalities using procurement data from January 2007 to December 2022. Drawing from the Principle of Relatedness from economic complexity, we aim to uncover the underlying dynamics and factors influencing municipal spending behaviors. Through a comprehensive examination of this extensive dataset, the research sheds light on the interconnectedness of municipalities, their financial decision-making processes, and the broader economic implications. The findings not only offer insights into the intricacies of municipal expenditures but also contribute to the broader discourse on economic complexity and its application in understanding regional financial behaviors.

Introducción: La tuberculosis es una enfermedad infecciosa producida por mycobacterium tuberculosis. Afecta más frecuentemente a pulmón, pero también puede ser multisistémica. Existen medidas gubernamentales de control de la enfermedad que han surtido un efecto en su incidencia y mortalidad, persistiendo en grupos vulnerables en el que se concentran los casos y mortalidad. Metodología: Se recabaron datos secundariamente; Anonimizados y públicos, del Departamento de Estadísticas e Información de Salud del Ministerio de Salud de Chile (DEIS) desde los años 2002 al 2019. Se analizaron datos epidemiológicos de egresos y mortalidad por enfermedades causadas por TBC en Chile. Resultado: En el año 2019 se registraron en total 1.517 egresos hospitalarios por TBC, con una tasa cruda de 7,94 por cada 100.000 habitantes. Respecto a la mortalidad, en el año 2019 se registró una tasa de mortalidad cruda de 0,98 por cada 100.000 habitantes. Tanto para egresos hospitalarios como para mortalidad se ve un mayor riesgo en hombres y en personas mayores de 80 años. Discusión: La mortalidad por TBC en Chile ha seguido la tendencia internacional a la baja, mientras que, la incidencia en Chile se había estancado hasta 2014 momento desde el cual ha sufrido un incremento hasta 2019. Al igual que lo que se observa a nivel internacional los grupos de mayor riesgo son los hombres y personas mayores de 75-80 años. Conclusión: El análisis del impacto de la TBC a nivel nacional se correlaciona con el observado a nivel internacional con un mayor impacto en poblaciones de riesgo.

Microstrip Planar Antennas for C-Band Wireless Applications
Authors: Sharan Bhagwati , Sagar Anil Kumar , Rajak Nidhi
Published: April 2024

In recent years, wireless communications have evolved significantly, and many mobile devices have reduced in size. The antennas used in mobile terminals must be lowered in size to fulfil the downsizing standards. Planar antennas, like microstrip and printed antennas, have a low profile, compact size, and conformability to mounting hosts, making them particularly desirable candidates for achieving these needs. Additionally, planar antennas are also being used in communication devices for 2.4 GHz (2400 – 2484 MHz) and 5.2 GHz wireless local area network (WLAN) systems (5150). In wireless applications, an antenna is a crucial component. At the transmitter, it transforms electrical signals into RF signals, and at the receiver, it converts RF signals to electrical signals. The patch inside the antenna is made of a conducting material such as Cu (Copper) or Au (Gold), and it can be rectangular, round, triangular, or elliptical. Two unique designs of microstrip planar antennas with an operating frequency of 5.2 GHz having S11 parameters as -16.0 dB and -15.7 dB have been offered and their performance has been studied in this research article.
Evaluating the Anti-proliferative and Apoptotic Role of Atrial Natriuretic Peptide in Colon Cancer Cell Lines
Authors: Das Alakesh , Deka Dikshita , Banerjee Antara , Pathak Surajit
Published: April 2024

The use of small peptides and conventional anticancer drugs is gaining importance in oncology as small peptides may help increase chemo or radiation sensitivity. The present study aimed to study the impact of atrial natriuretic peptide (ANP) in reducing colon cancer cell proliferation in primary and metastatic colon cancer cell lines. The proliferation of colon cancer cell lines (SW480 and SW620) was analysed by CCK-8 assay and cell damage was analyzed by lactate dehydrogenase activity. Catalase activity assay was performed to measure the oxidative stress and antioxidant defense mechanisms in SW480 and SW620 cell lines. Subsequently, up or downregulation of cancer-specific gene expression such as BAX, Caspase-3, BCL-2, CDK-6, and PCNA genes were assessed after the treatment of small peptide ANP in SW480 and SW620 colon cancer cell lines. The ANP treatment decreased the colon cancer cell proliferation, upregulated the apoptosis-related gene expression (Caspase-3, BAX), downregulated the anti-apoptotic gene (BCL-2) expression, and proliferation-related genes (CDK-6, PCNA) in SW480 and SW620 colon cancer cell lines, and the differences were found to be statistically significantly. Further, increased levels of catalase in the colon cancer cell lines after ANP-treatment suggested the therapeutic role of ANP. Subsequently, the LDH analysis showed the potential of ANP in inducing colon cancer cell damage. Collectively, the current study clearly shows that ANP is a potential molecule in reducing uncontrolled cancer cell growth. However, additional research using animal models and additional colon cancer cell lines is needed to validate its potential usage in clinical studies.

Osteoarthritis (OA) is the most common chronic disease of joint and a major cause of joint pain and disability. Traditional therapies for knee osteoarthritis show little clinical benefit, and the terminal treatment option is joint replacement. Currently, cell therapy is prospective for the treatment of knee osteoarthritis and has shown significant results in animal studies and human clinical trials. The aim: to investigate the treatment results in patients with knee osteoarthritis using adipose tissue stromal-vascular fraction and synovial mesenchymal stem cells.Methods. 60 patients with knee osteoarthritis were included in the study. The stage of knee osteoarthritis was assessed using the Kellgren-Lawrence classification, and patients with stage II-III of osteoarthritis were included in this study. After arthroscopic debridement, patients were divided into 2 groups. The first group was injected with the stromal-vascular fraction (SVF) of synovial membrane, and the second group was injected with adipose tissue mesenchymal stem cells (SVF). The minimum clinical and radiologic follow-up period was 12 months. Results. The assessment of the joints condition after 12 months using different scales showed that in both experimental groups there was a significant improvement of the functional status of the knee of the patients after treatment with MSC and SVF. Functional indicators of knee joints on the WOMAC scale improved by 14.7 and 13.4, on the KOOS scale by 23.6 and 26.4 in the SVF and MSC groups, respectively. Pain syndrome regressed by 1.8 and 2.1 on the VAS scale in the SVF and MSC groups, respectively.Conclusion. The results of both study groups showed that there is a significant difference between WOMAC, VAS and KOOS values before and after surgery (8, 12 weeks and 12 months) in the compared groups towards improvement

The aim of the study appears to focus on identifying and analyzing errors or inadequacies within the organization of specialized care for patients who have experienced traumatic amputation of hand segments. The specific goals might include understanding the flaws in the existing care structures, improving patient outcomes, and developing recommendations to enhance the quality of specialized care provided to patients who have suffered hand segment amputations.Methods. 2020 to 2022 to the clinic of the National Scientific Center for Surgery named after Syzganov, 165 patients with acute injuries of limb segments were urgently hospitalized to provide specialized surgical care, leading to decompensation of blood circulation in the hand or fingers. Results. Due to incorrect actions in 24 patients, it was not possible to replant the delivered segments (33 segments). These patients underwent stump formation.At the same time, 50-75% still allow diagnostic, technical and tactical errors in the treatment of this category of patients. The possibility of replantation and revascularization, as well as their outcome, largely depended on the timeliness and quality of first aid, compliance with the conditions for preserving the cut-off segment, the speed of transportation and other organizational factors. Conclusions. The use of modern methods of microsurgical restorative interventions with the reconstruction of injured vessels can significantly expand the possibilities of preserving and restoring completely and partially torn segments of the hand and fingers. The improvement of the results of treatment of patients with traumatic amputations and injuries of the neurovascular bundles of limb segments was significantly affected by the provision of timely specialized microsurgical care

The problem of postoperative pain after knee replacement is a significant problem that worsens the condition of patients and impedes the activation and rehabilitation of patients. To prevent the development of severe pain after knee replacement, local infiltration analgesia has been proposed, including an anesthetic drug, a non-steroidal anti-inflammatory drug and adrenaline.Purpose of the study: to evaluate the effectiveness of local infiltration analgesia in knee replacement with assessment of postoperative pain.Methods. A single-center retrospective study examined the outcomes of 81 patients with knee osteoarthritis who were scheduled for primary knee replacement between January 2022 and December 2023. Patients in the main group (40 people) were administered a single dose of local infiltration analgesia intraoperatively, while patients in the control group (41 people) did not. The results were compared in terms of postoperative pain and narcotic analgesic consumption in both groups.Results. Patients in the study group had significantly lower pain scores from the first postoperative day (VAS was 3.05) to the fourth postoperative day (2.75) compared with the control group (5.06 and 3.2) (p<0.001) . The consumption of narcotic analgesics in the main group was also much lower compared to the control group.Conclusions. The use of local infiltration analgesia during surgery can effectively reduce postoperative pain and the need for narcotic analgesics in patients with knee replacement.Key words: endoprosthetics, infiltration analgesia, knee joint, postoperative pain.

Purpose of the study: to study the macro and microscopic state of tendon grafts at various times after arthroscopic implantation for damage to the anterior cruciate ligament of the knee joint.Methods. Primary arthroscopic ACL repair with a quadriceps tendon graft was performed in 678 patients. In 496 observations, a graft with a bone block from the upper pole of the patella was used, in 182 observations, a tendon graft without a bone block was used. In 206 cases graft fixation was carried out intratunnel with metal interference screws, in 340 cases - with biodegradable screws, in 132 cases - with metal and biodegradable screws.In 47 cases, arthroscopic removal of metal screws was performed within a period of 5 months to 2.5 years from the date of surgery, which made it possible to arthroscopically and histologically study the nature of graft remodeling. The anatomical and biomechanical features of such plastic material are considered, indications and contraindications for surgery are determined. The advantages and disadvantages of various methods of graft fixation are presented, and specific complications when using bioabsorbable screws are described.Results. Based on 47 revision operations, an arthroscopic classification of the functional states of grafts at various times after surgery was developed. 6 types of grafts are presented with a detailed description of each of them. The state and quality of graft remodeling was histologically studied up to 2.5 years after surgery.Conclusions. Analysis of the clinical material allowed the authors to conclude that the quadriceps tendon graft is an excellent plastic material for both primary and revision reconstruction of the anterior cruciate ligament.Keywords: knee joint, arthroscopy, anterior cruciate ligament, arthroscopic reconstruction of the anterior cruciate ligament, autograft.

Published: April 2024

Road traffic accidents occupy the first positions due to severe combined injuries of the population. One of the most dangerous and poorly diagnosed complications of the acute period of combined skeletal injury is the syndrome of fatty embolism with predominant brain damage. Despite the large number of proposed methods and treatments for this complication, the mortality rate remains very high at the moment. A clinical case of successful treatment of multiple fatty embolism of the microvascular bed of internal organs with predominant brain damage in a patient with severe concomitant trauma is presented. Despite the difficulties of diagnosis and treatment, a high percentage of disability, complications and mortality, and the difficulty of preventing this complication of fat embolism with a predominant manifestation in the form of cerebral fat embolism, a favorable outcome is possible for patients with concomitant trauma.Keywords: traffic accident, fractures of long bones, traumatic shock, polytrauma, fat embolism, cerebral fat embolism, intensive care.

The precise control of the feed system of the rotary cutting machine is the key to achieving uniform thickness rotary cutting of wood on the log-core veneer lathe. The application of Improving the Extreme Learning Machine Model in the feed system can effectively solve the problem of unstable feed rate matching in traditional control methods. This study analyzed the working mechanism of log-core veneer lathe and established a kinematic model of its feed system. Using the thickness and thickness variation of the wooden board as the control results of Improving the Extreme Learning Machine Model, in order to solve the optimal weight and threshold of Improving the Extreme Learning Machine Model, this paper uses an improved particle swarm optimization algorithm to solve. Finally, in the Matlab software environment, log-core veneer lathe motion model and control model are written, and simulation experiments are conducted to verify. The results show that Improving the Extreme Learning Machine Model effectively improves the control performance of the system, with stable feed rate changes, good real-time performance, fast convergence, high control accuracy, and strong adaptability.

 
A Travel Salesman Problem Solving Algorithm Based on Feature Enhanced Attention Model
Authors: Xiaoxuan Ma Xiaoxuan Ma , Xiaoxuan Ma Chao Liu
Published: April 2024

In order to address the challenges of low accuracy and weak generalization capabilities in solving the traveling salesman problem (TSP) using end-to-end deep reinforcement learning (DRL) algorithms, this paper introduced a novel solution. This solution consisted of a feature enhanced attention model (FEAM) and a rotation expanded inference method. The FEAM combined a feature filtering layer, a graph embedding layer, and Transformer architecture in the encoder to better capture the complex relationships between cities, obtain richer and more accurate node representations, and thereby improved the model’s solving accuracy and generalization ability. The rotation expanded inference method generated new problem instances through coordinate rotation, enabling the model to consider path planning strategies from multiple perspectives, thus further enhancing solution accuracy. Numerous experiments on randomly generated benchmark datasets and public benchmark datasets show that the proposed end-to-end DRL algorithm performed better than other DRL algorithms in terms of solution quality and generalization ability.

 
Mourning Women, the Voice of God, and the Limits of Lament: Women’s Songs of Lament in Jeremiah
Authors: Beal Lissa M. Wray
Published: April 2024

The book of Jeremiah contains metaphors depicting Israel and Zion as a woman. These include the city as a mourning woman (4:19–21; 10:20). Real mourning women are addressed in Jer 9:17–22, following laments variously attributed to Jeremiah and/or Yahweh (8:18–9:2, 10). Working with the (MT) canonical form and engaging the insights of trauma studies, this article traces linguistic and thematic connections between the two passages before tracing similar connections to Rachel’s lament (Jer 31). The mourning women in Jer 9 serve a societal role by giving voice to lament; this effective power is affirmed by trauma studies. When read alongside the lament by Jeremiah and/or Yahweh, this article notes the women also take up a prophetic role as with Jeremiah they embody and express Yahweh’s own pathos. In ch. 31, the mourning women are metaphorically instantiated in the eponymous mother who also voices Yahweh’s pathos yet remains uncomforted. This study points to the hope that arises from Yahweh’s identification with his people in the pathos expressed by prophet, mourning women, and Rachel. Ultimately, Yahweh’s identification with his people, and his words of hope offer comfort to unrequited lament.
El dramaturgo es quien construye el personaje: el duque de Gloucester de Shakespeare y el de Ferrara de Lope
Authors: Benabu Isaac
Published: April 2024

Hace unos años el distinguido y añorado crítico de la comedia, Francisco Ruiz Ramón, se planteaba una hipótesis de trabajo acerca de la lectura de los textos de teatro de obras clásicas, cuya pregunta serviría para descifrar tanto para el actor como para el crítico académico las dificultades de estos textos, compuestos hace varios siglos: “¿No estarán las soluciones a los problemas del texto clásico en el texto mismo?” (144). La pregunta de Ruiz Ramón coincide con las cuestiones que el presente artículo se propone plantear: la problemática de la lectura de las obras de Shakespeare como de las comedias del Siglo de Oro español, como textos destinados en primer lugar a la representación. Esta aproximación al texto, enfocada específicamente desde un punto de vista teatral, abarca diferentes parámetros, y se diferencia de las muchas lecturas que se han hecho basadas en criterios adoptados de la crítica literaria.
Dog Eat Dog: Staging Female Rivalry in David Johnston’s Translation of Lope’s The Dog in the Manger
Authors: Voros Sharon D.
Published: April 2024

Staging female rivalry for today’s audiences presents a multiplicity of problems in producing Golden Age Spanish plays. In Lope de Vega’s El perro del hortelano, the lady Diana, Countess of Belflor, eventually wins out against her rival, her own lady-in-waiting, Marcela. A further complication arises since the love interest is the Countess’s low-born secretary, Teodoro. Stage action from Marcela’s perspective informs the main plot, the love game between Diana and Teodoro. Marcela questions: “When can honor and love ever meet” (112), a line recalling Donald Larson’s notion of feminine vergüenza that involves the Countess’s social status. I discuss David Johnston’s translation as an effort to unravel comedic enredos with contemporary language, along with the performance at the Shakespeare Theatre Company in Washington, DC, in 2009. The bonds of matrimony serve to bring order out of delightful theatrical chaos that in the hands of this translator becomes witty comedic action.
