Authors: Ginindza Vuyisile , Nyirenda Makandwe , Hlongwa Mbuzeleni , Ginindza Themba G.
Published: July 2024

Background

Uterine fibroids are the most common pelvic benign tumours found in reproductive-aged women and may affect up to 70% of all women by menopause. Uterine fibroids place a heavy burden on women and society resulting in poor quality of life, impaired self-image, and impaired social, sexual, emotional, and physical well-being of affected individuals.

Aim

This study aims to map the evidence on the burden of uterine fibroids in Sub-Saharan Africa; uterine fibroids’ burden by age, uterine fibroids’ geographic burden, uterine fibroids’ cost estimation and reported experiences among women diagnosed with uterine fibroids.

Setting

Articles will be selected from countries within Sub-Saharan Africa

Methods and analysis

This scoping review will be guided by the Arksey & O’Malley framework, enhanced by Levac et al (2010). The following electronic databases will be searched; PubMed, EBSCOhost (Cumulated Index to Nursing and Allied Health Literature and Health Source), Medical Literature Analysis and Retrieval System Online, Cochrane Library, Scopus, Web of Science, Africa Journal Online, and Google Scholar. The Population Concept and Context (PCC) framework will be used and the PRISMA flow diagram will also be used to show the literature search and selection of studies. Descriptive data analysis will be used; results will be presented in themes, narrative summaries, tables, and charts.

Discussion

The study anticipates finding relevant literature on the distribution of uterine fibroids, the burden of uterine fibroids in terms of geographic distribution, age distribution, and cost approximation related to the disease. This will assist in identifying research gaps to guide future research contribute to the body of scientific knowledge and develop preventative strategies for the disease.
Effects of different exercise types and cycles on pain and quality of life in breast cancer patients: A systematic review and network meta-analysis
Authors: Dong Jin , Wang Desheng , Zhong Shuai
Published: July 2024

Purpose

To determine the effect of different combinations of different exercise modalities with different training cycles on the improvement of quality of life and pain symptoms in breast cancer patients.

Methods

The databases PubMed, Web of Science, Embase, and Scopus were searched through a computer network with a search deadline of 23 August 2023. Two researchers independently screened the literature, extracted data and performed methodological quality assessment of the included literature, and then performed the corresponding statistical analyses and graphing using stata17.0.

Results

Thirty-six randomized control trial (RCT) studies involving 3003 participants and seven exercise modalities were included. Most of the exercise modalities improved patients’ quality of life compared to usual care, with long-term aerobic combined with resistance exercise [SMD = 0.83,95% CI = 0.34,1.33,p = 0.001] and YOGA [SMD = 0.61,95% CI = 0.06,1.16,p = 0.029] treatments having a significant effect. For pain and fatigue-related outcome indicators, the treatment effect was not significant for all exercise modalities included in the analysis compared to the control group, but tended to be beneficial for patients.

Conclusion

Long-term aerobic combined with resistance exercise was the most effective in improving quality of life and fatigue status in breast cancer patients, and aerobic exercise was more effective in improving pain symptoms in breast cancer patients.

Authors: He Lvfu , He Weimin
Published: July 2024

Background

The present study reviewed the clinicopathological features and outcomes of bilateral lacrimal gland lesions.

Methods

The data of 113 patients who underwent lacrimal gland biopsy at the West China Hospital of Sichuan University, China, between January 1, 2010, and December 31, 2021, are presented in this case series. The patients all presented with bilateral lacrimal gland lesions. The collected data included patient demographics, clinical features, the results of laboratory examinations, imaging presentations, histopathological diagnoses, treatments, and outcomes.

Results

The mean age of the 113 enrolled patients was 47.4 ± 14.9 years (range, 11–77 years) with a predominance of females (54.9%, n = 62). The lacrimal gland was the source of the majority of biopsy tissue (98.2%, n = 111). The most prevalent etiology was immunoglobulin G4-related ophthalmic disease (IgG4-ROD) (32.7%, n = 37), followed by idiopathic orbital inflammation (IOI) (28.3%, n = 32), mucosa-associated lymphoid tissue (MALT) lymphoma (17.7%, n = 20), reactive lymphoid hyperplasia (RLH) (10.6%, n = 12), and mantle cell lymphoma (4.4%, n = 5). Patients with IOI were significantly younger than those with IgG4-ROD and MALT lymphoma (t = 2.932, P = 0.005; t = 3.865, P<0.001, respectively). Systemic symptoms were more prevalent among patients with IgG4-ROD (χ2 = 7.916, P = 0.005). The majority of patients were treated with surgery (53.1%, n = 60), with surgery combined with corticosteroid therapy (21.2%, n = 24) being the second most common treatment. The majority of patients (91.2%, n = 103) attained complete resolution, stable disease, or significant improvement.

Conclusion

In conclusion, there are several aetiologies associated with bilateral lacrimal gland lesions, the most prevalent being IgG4-ROD, IOI, and MALT lymphoma. Systemic symptoms were more common in patients with IgG4-ROD. The majority of patients who presented with bilateral lesions of the lacrimal glands responded satisfactorily to treatment, with favorable results.
La extensión universitaria a través del registro. Aportes y reflexiones sobre una herramienta metodológica
Authors: Bácerez María del Valle , Díaz Nanci
Published: July 2024

La presente contribución propone abordar al registro como herramienta metodológica situada en el ámbito de la extensión universitaria y en relación con los procesos de aprendizaje en los dispositivos. El objetivo es, por un lado, presentar las principales características de la construcción de registros de las experiencias a lo largo de las prácticas de extensión, sus alcances y limitaciones. Por otro lado, reflexionar sobre las instancias pedagógicas donde realizamos la lectura de esos registros, un “descentramiento teórico” en que nos permiten establecer asociaciones, formular preguntas impensadas, generar hipótesis. Dos momentos que se retroalimentan.En este sentido, consideramos que el registro es una herramienta metodológica de sumo valor cognoscitivo que permite recuperar las experiencias y se convierte en materia prima para la interpretación y análisis de esos procesos, en diálogo con la teoría a través de instancias de escritura.

Authors: Lorenzetti Mariana Isabel , Pedrini Ana Gabriela , Almada Jorge Sebastián
Published: July 2024

Nos proponemos analizar las articulaciones entre la perspectiva etnográfica y la cartografía social de una experiencia de investigación colaborativa centrada en la reconstrucción de los cuidados comunitarios en salud que se vienen desplegando en algunos barrios periurbanos de Posadas tras la pandemia de COVID–19. Para ello, retomamos las discusiones del campo de estudios de los cuidados, género y el reconocimiento de derechos y explicitamos el encuadre desde el cual delineamos la modalidad de trabajo con referentes de la Coordinadora de Trabajadores Desocupados Aníbal Verón. Luego, nos detenemos en las vinculaciones entre la etnografía y la cartografía social como modo de producir conocimiento de carácter procesual y colaborativo. Si bien ambas vías de acceso a la configuración de los territorios vividos provienen de disciplinas distintas (antropología y geografía social), consideramos que retroalimentan las posibilidades de articular la participación de las/os interlocutores en el hacer investigativo–reflexivo sobre las problemáticas de salud.

To ascertain the comparative effects of ripe and unripe Lime (Citrus aurantifolia) on spermatozoa and gonadosomatic index evaluation in matured male Wistar rats; exploring the idea that both ripe and unripe Lime (Citrus aurantifolia) might or might not positively affect semen quality, crucial for male fertility. Twenty-eight (28) sexually mature male Wister rats, aged 9–10 weeks and weighing between 211.50g and 217.00g, were divided equally into seven groups (1 to 7); with Group 1 serving as the control and Groups 2 to 7 receiving 25%, 50%, and 75% concentrations of ripe lime juice (RLJ) and unripe lime juice (ULJ) respectively. The findings indicated that ULJ had a higher concentration (0.1mg/ml) compared to ripe lime RLJ at 0.08mg/ml, although both had approximately the same LD50 value of 1581.138mg/kg. RLJ, at different concentrations, adversely impacted the reproductive performance of rats, leading to decreased progressive motility, livability, sperm count, testicular size, and sexual drive. However, ULJ did not exhibit these effects. A 75% concentration of RLJ showed anti-prostatic activity, causing a reduction in prostate size, which was more pronounced than that of the same ULJ concentration. Importantly, both RLJ and ULJ did not have a significant impact on the sizes of the liver, spleen, heart, kidneys, and lungs, with these visceral organs maintaining normal sizes comparable to the control group (statistically, p>0.05).The findings suggest that RLJ or ULJ consumption, particularly at the highest concentration, may lead to alterations in reproductive performance, hence such consumption should be discouraged.

Authors: Nainggolan Kristina Novalina , Putra Yudha Perdana , Fitriyani Evi
Published: July 2024

Generally, chitin is isolated chemically. An environmentally friendly alternative to chitin extraction is enzymatic extraction. The research aims to determine the effectiveness and optimum conditions for enzymatic chitin extraction of shrimp waste (heads, shells, and tails) using lactic acid bacteria (LAB) and proteolytic bacteria from the shrimp's digestive tract (faeces and intestines). The research stages were isolation, enrichment, and determining shrimp digestion's bacterial colonies, microscopic identification of shrimp digestive bacteria, and determining the effectiveness and optimal conditions for shrimp waste's chitin isolation. Aerobic and Anaerobic Total Plate Count (TPC), LAB, and proteolytic bacteria from shrimp's digestive tract per gram of sample were respectively 5.52 and 5.59 log CFU; 4.76 and 4.56 log CFU; 6.46 and 6.20 log CFU. Microscopic morphology shows that LAB and proteolytic bacteria of shrimp digestive are gram-positive as cocci or rods. The deproteinization value of shrimp waste reached 31%, especially for treatment with a pH of 5.0–7.0 (during proteolytic bacteria fermentation) and pre-treatment of boiling, drying and coarse grinding of shrimp waste (PP2) before extraction. However, the demineralization value of shrimp waste is only 4.5% (PP1) and 3% (PP2), with LAB as the primary fermentation agent because proteolytic bacteria have been unable to reduce the mineral content in shrimp waste further.
The Role of the United Nations and Its Agencies in the Israel-Hamas War

Published: July 2024

Institutional Liberalism, an International Relations theory argues that international institutions play a significant role in influencing cooperation and peace among nations. Although criticized by some as unrealistic, the tenets of Liberal Institutionalism have contributed to the rising interest in the capabilities of international organizations like the United Nations (UN) in ensuring long-lasting international relations and peace among countries after the Cold War Era. This is due to their mediation ability that provides a ‘common ground’ for discussions among states while maintaining the common interest of each state actor. It is considering this tenet of Institutional Liberalism that we explore the role of the UN and some of its agencies in the ongoing Israel-Hamas war of 2023. The involvement of the UN in the Israeli-Palestinian tension dates back to November 29, 1947, when the UN General Assembly voted to divide Palestine into Jewish and Arab states with Jerusalem as its international city (Resolution 181- Partition Plan). However, the focus of this article is limited to the October 7, 2023, Israel-Hamas war, as the role of the UN and its agencies have been active in mediating international relations in a manner supported by the theory of Liberal Institutionalism. The agencies under consideration in this article include the UN General Assembly, UN Security Council, International Court of Justice, UNHCR, UNRWA, UNESCO, UNICEF, and WFP. This article is, however, limited to a few UN agencies and, as such, gives room for further research as to the role of unexamined UN agencies as well as other international institutions in the ongoing 2023 Israel-Hamas war.
Usługi wczesnego wspomagania rozwoju dziecka w prawie oświatowym
Authors: Behr Jolanta
Published: July 2024

Early support for child development is a form of targeted and specialized support for a child who has not yet started fulfilling educational obligations. It is implemented in order to stimulate the child’s psychomotor and social development, from the moment of detecting a disability until the child starts school. It  is intended to prevent potential future failures in school education. Early support for child development is a conglomerate of public services whose type, scope and frequency of provision are adapted to the needs of a specific child, and take into account their individual limitations. The right to use these services stems from an opinion issued by the adjudicating panel of a public psychological and pedagogical counseling center confirming the child’s need for early development support. The article discusses the legal aspects of the public task of organizing and providing services in the field of early development support. The aim is to explain the meaning of the concept of early support for child development, discuss the legal provisions regulating them and determine the ratio legis of their introduction into the Polish legal system. It also involves identifying intangible services falling within the scope of early support for child  development, determines their beneficiaries and identifying the entities providing them. In the context    of acquiring the right to use these services, special attention will be paid to the opinion issued on the need to support early child development, in particular, the procedure for its issuance it and its components. In order to achieve the research goals, the dogmatic-legal method will be used, consisting of the analysis and interpretation of the texts of legal acts. Administrative court jurisprudence regarding the subject of the article will also be taken into account to the required extent.
Nieczytelność oświadczenia o stanie majątkowym jako przesłanka do stwierdzenia jego bezskutecznego złożenia
Authors: Jaworski Arkadiusz
Published: July 2024

Declarations of ﬁnancial interests are considered one of the key elements of the Polish anti-corruption system. Unfortunately, due to the negligence of the legislator, there are often numerous practical problems that control authorities have to deal with. One of them is the illegibility of the submitted declarations, which makes it impossible to verify their content. This is a serious shortcoming that makes it difficult to control persons holding public functions and can be used to circumvent the imposed obligations.This text considers whether, despite the lack of detailed regulations regarding the “style” of completing the declaration of interests, control authorities are forced to accept documents that cannot be veriﬁed. In the author’s opinion, the directive of a rational legislator requires just the opposite, in order to ensure the effectiveness of such key provisions from the point of view of democracy as anti-corruption provisions. Refusal to accept the declaration should be made by applying, by analogia legis, the provisions of art. 64. § 2 of the Code of Adminisrative Procedure – by ﬁnding a formal deﬁciency and requesting its correction. The criterion of readability itself should be based on the pattern of the average recipient, developed on the basis of the principles of knowledge, life experience and logical reasoning. This position, supported by case law and general principles of administrative proceedings, allows for the proper functioning of this element of the anti-corruption system, while protecting the rights of the obliged person.
Child Labor, Corruption, and Development
Authors: Miyashita Toshiki , Okada Kohei , Takakura Kei
Published: July 2024

Employing an overlapping generations model with endogenous education choice and corruption, we investigate how child labor and corruption influence human capital accumulation and development. We show that multiple steady states exist in the economy. One steady state has a high level of human capital, while the other has a low level of human capital. In the steady state with a low level of human capital, child labor and corruption exist, fertility and child mortality rates are high, and the welfare level is low. Conversely, in the steady state with a high level of human capital, child labor and corruption are diminished, fertility and child mortality rates are low, and welfare is high. In addition, we show that it is difficult to steer an economy away from a poverty trap with child labor and corruption because bureaucrats of the current generation are opposed to policy changes, such as the reinforcement of monitoring and penal regulations. However, we highlight the possibility for the government to develop the economy in the poverty trap by implementing an education policy, which is Pareto improving.
Cognitive and sociolectal constraints on the theme-recipient alternation: evidence from Mandarin
Authors: Li Yi
Published: July 2024

We explore the cognitive and sociolectal constraints that probabilistically regulate the theme-recipient (or “dative”) alternation in modern varieties of Mandarin and how these constraints interact with each other. Based on an extensively annotated corpus dataset and regression modeling, we found that the probabilistic grammar that shapes the theme-recipient alternation is fundamentally stable across regional and genre varieties of Mandarin. This general stability notwithstanding, significant variation regarding the importance of cognitive constraints across different sociolectal constraints is detected. Crucially, the analysis revealed that recipient syntactic complexity has a much greater effect in Taiwan Mandarin than in Mainland Mandarin. The effect of theme concreteness is also found to be significantly reduced in telephone conversations compared to broadcast news. Corpus-based findings were cross-validated using a psycholinguistic rating task experiment. While the results of the two approaches demonstrate substantial overlap, they also exhibit diverging patterns at the level of interaction between regional variety and recipient complexity, potentially indicating nuanced differences between the two approaches. The findings provide evidence that interactional patterns between cognitive and sociolectal constraints on probabilistic grammatical alternations may be shared across languages, despite their distinct socio-cultural factors that shape variation in human interaction.
Analysis of Demographic Variables Affecting Digital Citizenship in Turkey
Authors: Akduman Gülbeniz , Karadal Himmet , Dinçer Evren
Published: July 2024

The new technologies generated by the digital age are changing how individuals and societies communicate, learn, work, and manage. Although digital citizenship is defined as the behavioral norms regarding the use of technology in the most general sense, it also includes ethical and appropriate behaviors and being informed about this issue while using technology. However, there is a generational gap in digital information and literacy. In this context, the research analyzes digital citizenship according to gender, age, number of children, job position, and education level. In this analysis, which was structured as exploratory research to examine the digital citizenship status of participants, the descriptive model was preferred over quantitative research models. According to the analysis results, it can be said that the participants’ digital citizenship behavior is in the range of “I am undecided” (at a moderate level). Citizenship behavior with the lowest score was “political activism on the internet.” The groups with a significantly higher level of digital citizenship are women, those between the ages of 22 and 42 working as managers, and those at the graduate level.

Competing constructions in Kaqchikel focus contexts
Authors: Heaton Raina
Published: July 2024

This study provides new data on the use of agent focus (AF) versus transitive constructions in Kaqchikel. This work follows up on a study done by Heaton et al. (Heaton, Raina, Kamil Deen & William O’Grady. 2016. An investigation of relativization in Kaqchikel Maya. Lingua 170. 35–46) which found that while questioning the subject of a transitive verb regularly requires the use of AF or an antipassive, relativizing the subject of a transitive verb does not. Present findings show that AF is only common in half of the six primary syntactic contexts that allow it, which is unexpected under the assumption that AF is a last resort strategy. I suggest that the differences between these syntactic contexts in Kaqchikel are related to the presence of a preverbal lexical NP element which is available to be interpreted as the agent. Comparative descriptive evidence is also compiled demonstrating that transitive verbs are possible in syntactic contexts that traditionally have been considered to require AF across Eastern Mayan languages.
Demultiplexing-free ultra-compact WDM-compatible multimode optical switch assisted by mode exchanger
Authors: Liu Siwei , Fu Xin , Niu Jiaqi , Huo Yujie , Cheng Chuang , Yang Lin
Published: July 2024

Silicon-based optical switches are integral to on-chip optical interconnects, and mode-division multiplexing (MDM) technology has enabled modes to function as carriers in routing, further boosting optical switches’ link capacity. However, traditional multimode optical switches, which typically use Mach–Zehnder interferometer (MZI) structures and mode (de)multiplexers, are complex and occupy significant physical space. In this paper, we propose and experimentally demonstrate a novel demultiplexing-free dual-mode 3 × 3 thermal-optical switch based on micro-rings (MRs) and mode exchangers (MEs). All MRs are designed to handle TE1 mode, while the ME converts TE0 mode to TE1 mode, enabling separate routing of both modes. Bezier curves are employed to optimize not only the ME, but also the dual-mode 45° and 90° waveguide bends, which facilitate the flexible and compact layout design. Moreover, our structure can support multiple wavelength channels and spacings by adding pairs of MRs, exhibiting strong WDM compatibility. The switch has an ultra-compact footprint of 0.87 × 0.52 mm2. Under both “all-bar” and “all-cross” configurations, its insertion losses (ILs) remain below 8.7 dB at 1,551 nm, with optical signal-to-noise ratios (OSNRs) exceeding 13.0 dB. Also, 32 Gbps data transmission experiments validate the switch’s high-speed transmission capability.

Expanding Verse: Japanese Poetry at the Edge of Media
Authors: Campana Andrew
Published: July 2024

Expanding Verse explores experimental poetic practice at key moments of transition in Japan’s media landscape from the 1920s to the present. Andrew Campana centers hybrid poetic forms—many of which have never been examined in detail before—including the cinepoem, the tape recorder poem, the protest performance poem, the music video poem, the online sign language poem, and the augmented reality poem. Drawing together approaches from literary, media, and disability studies, he contends that poetry actively aimed to disrupt the norms of media in each era. For the poets in Expanding Verse, poetry was not a medium in and of itself but a way to push back against what new media technologies crystallized and perpetuated. Their aim was to challenge dominant conceptions of embodiment and sensation, as well as who counts as a poet and what counts as poetry. Over and over, poetic practice became a way to think about each medium otherwise, and to find new possibilities at the edge of media.
El campo constitutivo de la demanda: tiempo/espacio local, tiempo/espacio doméstico
Authors: Tasies Castro Esperanza , Chamorro Tasies Rocío
Published: July 2024

El artículo centra una discusión cuyo telón de fondo es el conflicto social acaecido en Costa Rica, durante un ciclo de protestas que se extendió los últimos meses de 2018. Como tesis principal se distingue el espacio tiempo local y el espacio tiempo doméstico. El espacio tiempo doméstico es considerado como espacio tiempo de las mujeres y es configurado por el poder patriarcal. Ambos espacios son formas específicas de subjetivación colectiva alrededor de las demandas de los movimientos sociales.
El texto examina los resultados de una investigación cualitativa (estudio de caso), a partir de organizar e interpretar los datos bajo las coordenadas del método que se conoce como “teoría fundamentada”. Mediante herramientas analíticas se categorizaron para su posterior codificación las formas de subjetivación subalterna y aquellos aspectos estructurales que configuran el contexto de lucha contra la reforma neoliberal del Estado.
En su proceso conclusivo, se analizan las posibilidades de emergencia de un sujeto histórico anclado en el campo de lo popular, en las coordenadas de espacio-tiempo local, en el que convergen múltiples formas de desigualdad. Como tesis emergente, se analiza el campo constitutivo de la demanda como expresión del antagonismo de un posible sujeto popular disruptivo.
De la resistencia al compartimiento: autocuidado de la salud e identidad masculina en contextos marginados
Authors: Olarte Ramos Carlos Arturo
Published: July 2024

This document shares the experience of working with men in male health self-care workshops carried out in contexts of marginalization, specifically, in two neighborhoods in the city of Villahermosa, Tabasco, in southeastern Mexico. He was part of a qualitative research on men, emotions and interpersonal relationships, which had the objective of exploring the experience of men during the Covid-19 pandemic, in addition to the vulnerability they present when living in flood-prone areas. The workshop was used as a data construction technique, since it allows reflection based on the constant interaction of the participants; for this purpose, a face-to-face invitation was made during tours in the neighborhoods, as well as by handing out flyers on public roads and on the WhatsApp social network. Resistance to male participation was identified both due to the social and work dynamics of which they are part and due to the sociocultural significance assigned to the male body and vulnerability; this indicates the need to establish meeting spaces between men to reflect on the social construction of masculinity, their emotions and reconstruct themselves as subjects with the right to affection.
La problematización del sujeto en Relaciones Internacionales. Una relectura a la luz de sus efectos analíticos y políticos
Authors: Cuadro Mariela
Published: July 2024

El artículo tiene un doble objetivo. En primer lugar, repasar analíticamente cómo el sujeto moderno emergió como problema en las Relaciones Internacionales. Para esto, se abordan las relaciones entre las discusiones epistemológicas y ontológicas que se dieron en el debate que tuvo lugar en la década de los ochenta del siglo pasado en la disciplina. Un segundo objetivo apunta a analizar los efectos del predominio de la concepción epistemo-ontológica sostenida sobre esta idea de sujeto en los modos de concebir lo político en las Relaciones Internacionales. Se postula que la idea de sujeto moderno aparece íntimamente vinculada a la de soberanía, dando forma a la concepción soberana del poder, es decir, a la forma sustancialista, centrada y represiva del mismo que prima en nuestras figuraciones de lo internacional y, por tanto, en el modo en que actuamos sobre el mundo. El cuestionamiento de este sustrato supuso la instauración de la idea de un poder relacional constitutivo del sujeto al que se denomina poder gubernamental. Así, la crítica al sujeto moderno efectuó un cuestionamiento de los modos de saber y del discurso de poder que sostienen tanto a la disciplina como a los modos de hacer política (internacional). El texto se estructura en cinco secciones y una conclusión. En la primera sección, se establecen las coordenadas que han definido históricamente al sujeto moderno como centro constituyente de la vida social. En la segunda, se abordan las críticas que se han realizado a este relato. En la tercera, se contextualiza la emergencia de la cuestión del sujeto en Relaciones Internacionales en el debate epistemo-ontológico. En la cuarta, se aborda la problematización de este sujeto en las Relaciones Internacionales y su impacto sobre la noción de soberanía. La quinta sección está enfocada en precisar los efectos de poder que supone esta crítica distinguiendo la noción de poder soberano de aquella de poder gubernamental. El artículo se cierra con algunas reflexiones finales.

The work considers one of the possible approaches to the creation of a capacitive type wireless charger, which allows for non-contact charging of batteries of small-sized vehicles: electric carts, electric scooters, electric scooters. The basis of the development of such a device is the operation of the hybrid DC-DC converter circuit, which operates at a high frequency (550 kHz), transfers energy to the charging circuit using two capacitive elements and allows receiving a constant regulated voltage on the load, which can be either lower or and more input DC voltage. A prototype of such a device has been developed and the results of its experimental research are given, which confirm the possibility of using this scheme for wireless charging of the battery. A Simulink computer model of such a device has been developed, which takes into account the real values of all parameters of the developed prototype and uses the basic model of a lithium-ion battery. According to the results of the calculations, it was determined that for the developed device of the capacitive type, and the largest losses occur in the inductor coils, the value of efficiency, which characterizes the efficiency of the process of transferring electrical energy from the primary power source to the battery, at the initial stage of its charging (when the parameter of the state of the battery SOC =50%) is 80%.

The peculiarities of the operation of closed systems of adjustable electric drives of single-cylinder reciprocating compressors due to the presence of a non-linear dependence between the motor load torque and the angular movement of its rotor are considered. The method of synthesis of the regulator of the amplitude of the supply voltage of an induction motor of such an electric drive at a fixed value of the supply frequency is proposed. According to the results of research, it was found that the effect of increasing energy efficiency (reducing the difference in efficiency for constant and periodic loads) due to the use of a voltage regulator increases with a decrease in the power supply frequency. It is shown that the optimization of the transmission coefficient of the voltage regulator of electric drives with a non-linear dependence between the motor load torque and the angular movement is expedient to be carried out according to the criterion of maximum efficiency.

Entre la representación y el silencio. “La Página del Pueblo” durante el primer año del magazín Mundial (Perú, 1920-1931)
Authors: Darrigrandi Navarro Claudia , Morales- Pino Luz Ainai
Published: July 2024

Objetivo: analizar la sección “La Página del Pueblo” (LPDP) de la revista Mundial en el período de la Patria Nueva de Augusto Leguía y del género magazín. Metodología: estudiamos LPDP durante el primer año de circulación de la revista ahondando en las problemáticas que plantea esta sección en un momento de aparente renovación político-social. Los ejes disciplinarios son: los estudios del campo revisteril, que brindan un marco para abordar las materialidades y comprender la singularidad de Mundial con respecto a otras publicaciones equivalentes en la región; los históricos, para insertar los temas y problemas en el mapa de las discusiones y coyunturas del momento; y los de cultura visual, con las pautas para analizar los entramados escritos-visuales y considerar la sección como la imagen-objeto concedida a un “pueblo” silenciado y vulnerado en otros apartados de la revista. Originalidad: no existen estudios sobre esta sección y tampoco estudios específicos sobre las secciones en Mundial. La presencia de grandes figuras del campo literario-intelectual, como Mariátegui, soslayó inquietudes sobre una publicación controversial que, aunque dio plataforma a intelectuales asociados con un pensamiento reivindicativo, se mantuvo, como plantea esta lectura del borde al centro, próxima a los intereses de la burguesía liberal y el pensamiento cristiano. Conclusiones: LPDP fue el espacio donde se discutieron las problemáticas de un grupo socionacional que permaneció como objeto de reflexión y no como sujeto político. La escasez de imágenes, la mediación ideológica y la infantilización, estos intentos de representación en realidad poco visibilizaban a los grupos sociales discursivamente sobreexpuestos.
Los fuegos que alimentaba el Cocinol. Combustibles domésticos, modernización, energía y política en Bogotá, 1970-1989
Authors: Medellín Pérez Iris Alejandra
Published: July 2024

Objetivo: analizar las diferentes formas de movilización desencadenadas en Bogotá por las crisis por combustibles domésticos en las décadas de 1970 y 1980 y, a partir de estas, explorar las tensiones de los proyectos de modernización de la ciudad, las articulaciones de lo político en la escala barrial y el impacto de las políticas energéticas a escala global en la vida doméstica. Metodología: se realizó un análisis de fuentes primarias, principalmente documentos internos de Juntas de Acción Comunal de 15 barrios periféricos populares bogotanos, con apoyo en prensa, panfletos y publicaciones periódicas. Originalidad: la modernización en las ciudades colombianas como Bogotá ha sido abordada por la historiografía principalmente desde el punto de vista del surgimiento de la planeación urbana, la regulación del espacio y las reformas de descentralización política durante el Frente Nacional, lo que incluye parcialmente la creación de Juntas de Acción Comunal en los barrios populares. Menos común es la discusión sobre lo que supuso dicha modernización en términos energéticos, qué desafíos enfrentó y las formas en que la discusión sobre política energética enlazaba escalas globales y locales de la experiencia histórica. Conclusiones: las relaciones de producción y distribución global de recursos energéticos durante la segunda mitad del siglo XX no están divorciadas de las experiencias históricas a nivel barrial y doméstico. Al analizar estos niveles se muestra una politicidad ambivalente que desafía la dicotomía moderna entre lo público y lo privado.

Antonio José Echeverry Pérez y Mariana Rivera Zapata ofrecen al lector un trabajo sobre el sacerdote guerrillero Camilo Torres Restrepo. Se trata de un personaje que desde su muerte en combate en las filas de la guerrilla colombiana del Ejército de Liberación Nacional (ELN) ha despertado el interés de muchos investigadores. Los autores afirman que en la base de datos construida durante la escritura de su texto establecieron la existencia de 124 libros redactados sobre su vida y obra. En el universo de obras publicadas en torno a la figura de Camilo Torres se pueden observar diversas tendencias, desde la clásica biografía de tono hagiográfico surgida de la pluma de Broderick en Camilo, el cura guerrillero hasta textos que se ocupan detenidamente de solo una etapa de la vida de Torres, como es el caso de Valencia Tovar y su libro El final de Camilo, que trata de su incorporación a la guerrilla y su muerte, pasando por Cristianismo y Revolución, una compilación de los escritos de Torres, e incluyendo textos más vivenciales e íntimos, como Camilo Torres Restrepo. Profeta para nuestro tiempo, de autoría de uno de los amigos personales más cercanos a Torres.

En el caso de Alzate Echeverri, la publicación da continuidad a diferentes ideas desarrolladas por la autora en obras previas, específicamente en sus investigaciones sobre la historia y la alimentación en instituciones hospitalarias. Por su parte, los aportes previos de Gámez Casado sobre historia arquitectónica y militar permiten entender los cambios implementados en esta área a fines del siglo XVIII en Cartagena de Indias. En conjunto, las experiencias de investigación de ambos autores ofrecen al lector una interesante aproximación a la historia del Hospital de San Lázaro que aborda tópicos arquitectónicos, administrativos y sociales.
Negative self-assessment revisited
Authors: Sekizaki Hironori
Published: July 2024

This study aims to explore the fundamental and necessary unit in discourses that initiate with negative self-assessment. Since past research has mainly focused on the second assessment as a response to the negative self-assessment as the first assessment, it remains unclear how conversations progress beyond the second assessment. Data for the study were collected from a corpus of 20 same-gender Japanese dyad conversations between undergraduate students who had close relationships with each other. The participants talked about “areas that I am not good at or find difficult”. The study found that the participants typically exchanged rationales for the negative self-assessment and reached a consensus on their views regarding the assessment. The study concluded that confirming both sides’ views was prioritised over formally denying the negative self-assessment, and such confirmation was essential for gradually forming a consensus among the speakers.
Other-correction and epistemic imbalances in teacher–student interactions
Authors: Li Min , Yue Yang
Published: July 2024

Other-correction is a ubiquitous phenomenon in language, and has been extensively studied in conversation analysis and pragmatics. Nevertheless, the conditions of its occurrence still remain unclear. Based on Heritage’s theory of epistemics, the study unveils four distinct epistemic interaction patterns in which other-correction takes place, and endeavours to elucidate their associations with trouble sources, correction strategies, and correction positions. Empirical findings indicate that different epistemic interaction patterns of other-correction exhibit no discernible link with trouble sources, but manifest a statistically significant correlation with correction strategies and correction positions.
Imperialist Multispecies Aspirations
Authors: Watanabe Chika
Published: July 2024

Humanities and social science scholars have recently turned their attention to the embeddedness of microbes in human life as a potential way to decentre the human and thereby decolonise assumptions about the human conquest of the natural world. In this article, I argue that, before such claims can be made, careful historical, regional, and ethnographic analyses of human-microbe relations are needed. My case study of a Japanese sustainable development, agricultural, and environmental NGO shows that human attunement to microbes is not necessarily decolonial in the context of Japan’s modern history. In fact, discourses of human openness to microbial life find affinity with Japanese nationalism and imperialism. Through my analysis, I contribute to scholarship that reveals how environmental visions link up with conservative and right-wing politics.

Cuando las innovaciones pedagógicas proporcionan una alternativa en la educación: impronta de los principios pedagógicos del pasado en la acción educativa del siglo XXI
Authors: Fernández-Estébanez Carmen , Álvarez-Blanco Lucía
Published: July 2024

En educación, el término “alternativa” no sólo aglutina enfoques antagónicos al modelo tradicional, sino que también engloba iniciativas que combinan ideas y prácticas educativas desarrolladas en siglos pasados para transformar la “escuela”, en las que tanto familias como educadores promueven una educación formal basada en el respeto, la individualidad y la inclusión ecosistémica. Por consiguiente, y respondiendo a un interés socioacadémico, este artículo presenta una revisión teórica sobre proyectos educativos alternativos, caracterizados por una formación holística, de calidad, para la paz y en consonancia con la innovación que busca afrontar los retos inminentes de las sociedades líquidas.
El estudio de la experiencia escolar. Propuesta de un modelo de análisis interdisciplinario
Authors: Neut-Aguayo Pablo
Published: July 2024

El objetivo del artículo es elaborar un modelo para el estudio de la experiencia escolar. En esta dirección, y a modo de procedimiento metodológico, discutimos los presupuestos provenientes de distintas disciplinas –como los de la “pedagogía de la experiencia”, la “sociología de la experiencia” o los “enfoques biográficos”– en tres ejes analíticos centrales: la relación estructura/sujeto, excepcionalidad/ cotidianeidad y vivencia/sentido. Tras este ejercicio, proponemos un modelo interdisciplinario para el estudio de la experiencia escolar que integra los ejes puestos en discusión, ponderando sus implicancias conceptuales, procedimentales y analíticas.
