La vivencia del bullying como impulso en la elección de ser maestro
Authors: Rodríguez-Groba Ana , Vila-Couñago Esther , Fraga-Varela Fernando
Published: March 2024

Esta investigación tiene como objetivo indagar la influencia del bullying en la decisión de ser maestros. Se parte de 109 portafolios electrónicos elaborados en una materia del primer curso del Grado en Maestro de Educación Infantil por la Universidad de Santiago de Compostela (España), de los cuales se seleccionan diecisiete casos que aluden –de forma explícita o implícita– a vivencias de bullying. Se realiza un análisis cualitativo de contenido de estos portafolios, siguiendo un procedimiento de categorización inductivo-deductivo atendiendo a un criterio temático. Los resultados muestran los motivos por los que el alumnado reconoce esta situación, las consecuencias –sociales, académicas, de sufrimiento, etc.– y el papel de compañeros y docentes ante el maltrato vivido, predominantemente pasivo. Las conclusiones ponen en evidencia la relación entre haber sido víctima de situaciones de bullying durante la etapa escolar, la elección posterior de los estudios de maestro y la necesidad percibida de un rol más activo del profesorado. Se muestra, además, una demanda de formación específica sobre esta problemática en los estudios de grado universitario.

Authors: Da Silva Júnior Geraldo Alexandre , Lima da Silva Marcia Gorette
Published: March 2024

O ensino da argumentação nas aulas de ciências vem sendo difundido nos últimos anos, no que se refere as discussões teóricas, as estratégias, a inserção no currículo, aos cursos de formação de professores, entre outros. Desta forma, assumimos que durante uma atividade de ensino para fomentar a argumentação, há também presente, no discurso do docente, aspectos retóricos do processo argumentativo. Ao mesmo tempo, consideramos que a teoria da argumentação de Perelman e Olbrechts-Tyteca constitui um referencial teórico e metodológico que auxilia na análise de discursos argumentativos nas aulas de ciências. Portanto, neste artigo de pesquisa em educação em ciências experimentais, matemática e tecnologia, buscamos analisar o caráter argumentativo do discurso docente à luz da Teoria da Argumentação de Perelman e Olbrechts-Tyteca. Para compor nosso corpus de análise, selecionamos episódios de um conjunto de atividades desenvolvidas por uma professora da disciplina de química, na educação básica, de uma escola técnica federal, buscando identificar, nos discursos dos participantes, elementos da teoria. Para a análise dos dados utilizamos o aporte teórico da Análise Textual Discursiva. Como principais resultados observamos a intenção explícita da docente (Orador) em elevar a adesão à uma dada tese por parte do alunado (Auditório) por meio do convencimento ou persuasão. A dinâmica para o contato com os espíritos a fim de promover um debate e, posteriormente, avaliar os argumentos, favoreceu um processo metacognitivo de reflexão sobre os argumentos utilizados, apontando valores e a hierarquia destes, que reconhecidos pelos membros do Auditório e as técnicas adotadas pela docente, se apoiam em argumentos de dissociação dos conceitos. Concluimos que a teoria apresenta potencial enquanto ferramenta analítica para estudos sobre argumentação.

Authors: Reina-Reina María Yolanda
Published: March 2024

Este artículo de investigación presenta un estudio de caso cualitativo- interpretativo, en el que se especifican las características del Conocimiento Profesional Específico del Profesor de Tecnología (CPPT) en la categoría escolar de Diseño Tecnológico, a partir de lo que enseña un profesor de Tecnología dentro de la Educación Media en Colombia. El propósito de este documento es describir e interpretar el conocimiento que ha construido el profesor de Tecnología para abordar la enseñanza del Diseño Tecnológico, desde los referentes teóricos basados en su conocimiento profesional, como un sistema de ideas integradas entre los saberes: académicos, experienciales, guiones y rutinas, así como la interrelación que se da entre estos tipos de saber. A partir del discurso del profesor se construyeron las metáforas más representativas para cada uno de los saberes, las cuales han permitido interpretar y dar un sentido particular a la categoría escolar de Diseño Tecnológico en la escuela. Los resultados muestran que el CPPT se caracteriza por estar dirigido a la formación de personas reflexivas frente al proceso de diseño en la escuela, que va más allá del bosquejar, delinear o crear artefactos; es un proceso analítico, reflexivo y propositivo, con el que el profesor promueve en los estudiantes la reflexión de su entorno tecnológico, para que, de manera responsable y bajo principios éticos, puedan incidir en ello.
Saberes del alumnado de secundaria sobre el modelo de inmunidad y vacunas
Authors: Gómiz-Aragón Marta , Aragón-Méndez María del Mar , Oliva-Martínez José María
Published: March 2024

El presente artículo investiga el saber que tiene el alumnado de secundaria sobre la inmunidad y las vacunas, para lo que se empleó un cuestionario de respuesta abierta junto a su rúbrica de evaluación. Así la rúbrica contempla cuatro categorías de respuesta para cada pregunta, cuyos significados revelan el tipo de concepción que mantiene el alumnado. Los resultados cualitativos obtenidos manifiestan ideas poco acordes al modelo escolar de inmunidad; no obstante, un análisis de Rasch muestra un saber articulado, el cual es evidenciado a través de la unidimensionalidad de las medidas obtenidas. Lo anteriormente mencionado sugiere la posibilidad de utilizar las mismas como guía de un posible itinerario de progresión que facilite el aprendizaje de los estudiantes a lo largo de la enseñanza. Estos resultados no solo tienen implicaciones a nivel teórico y de la práctica del aula, sino que también conllevan a la validación de la rúbrica construida para su uso con esta población de estudiantes.

Published: March 2024

Este artículo es el resultado de la sistematización de una investigación con experiencias innovadoras en enseñanza de las ciencias, con miras a desarrollar una ciudadanía con sentido de pertenencia en el marco de las prácticas profesionales de profesores en formación inicial. Por tal motivo, se convocó a un grupo de ellos, para diseñar propuestas educativas centradas en los desarrollos del programa sobre el Patrimonio Natural y Cultural de la nación, vinculado a la historia de las ciencias como contexto de trabajo en el aula para la formación en química, con elementos identitarios diferentes y desde una perspectiva intercultural. Consecuentemente, se empleó una metodología centrada en investigación basada en el diseño (ibd) en la que los profesores en formación diseñan, estructuran, validan, implementan y evalúan sus propuestas didácticas desde el marco teórico propuesto. Los resultados obtenidos muestran que, recurrir a esta perspectiva y a los contextos, favorece el trabajo interdisciplinario, pone en diálogo las disciplinas científicas con otros campos de conocimiento; en particular, con los objetos patrimoniales. Así mismo, promueve el tránsito por los distintos tipos de identidades, lo que implica una alta carga motivacional y actitudinal, factor fundamental en los procesos formativos en ciencias.

Authors: Lima-Villeda Diana Natalia , Flores Macías Rosa del Carmen , Guzmán Cedillo Yunuén Ixchel
Published: March 2024

Diferentes estudios sobre el modelo del Conocimiento Tecnológico Pedagógico y de Contenido (tpack, por sus siglas en inglés) con tutores en línea, han aportado evidencia empírica sobre cómo se deben organizar algunas de las formas de conocimiento que el modelo propone; sin embargo, no se ha hecho un análisis integral en el contexto de su práctica. En el presente estudio se realizó un análisis sobre cómo se manifiestan y explican, a partir del modelo tpack, los conocimientos del tutor en línea en el aula virtual. De este modo, el diseño de investigación usado fue mixto, secuencial explicativo con dos fases conectadas: en la primera fase, los tutores (N=50) universitarios contestaron el cuestionario tpack para identificar diferentes formas de conocimiento, los resultados permitieron la selección de los informantes clave (N=13) para la siguiente fase, considerando un criterio de máxima variación, estos tutores respondieron a una entrevista secuencial semiestructurada. Así, mediante un análisis temático desde la aproximación de confiabilidad de codificación, se analizó un corpus de 120 cuartillas, donde se identificaron y definieron cuatro actividades al impartir una materia en línea: psicoeducativa, diseño, orientación y tecnológica. Para cada una, se definieron acciones llevadas a cabo y se identificaron los conocimientos tpack que las sustentan. Se concluye que la visión integrada sobre el tutor en línea articula la enseñanza universitaria en la educación a distancia virtual es útil para describir sus conocimientos desde el modelo.

Authors: Vargas Franco Alfonso , López Gil Karen , Torres Casierra Liana Mercedes
Published: March 2024

Este artículo de investigación buscó caracterizar las actitudes, prácticas y procesos formativos vinculados con la competencia digital en docentes de educación pública colombiana durante el periodo de confinamiento por Covid-19, situación que aceleró de modo vertiginoso la inserción de las tecnologías en los procesos de enseñanza y aprendizaje. Dentro de este estudio, 102 docentes adscritos a instituciones educativas públicas urbanas y rurales de Cali respondieron a un cuestionario electrónico con 34 preguntas de opción múltiple y 3 preguntas abiertas. Antes de la pandemia, se encontró que los participantes eran usuarios frecuentes de tecnologías digitales, particularmente de redes sociales; a pesar de ello, no contaban con formación suficiente para incorporarlas en su práctica docente. Del mismo modo, enfrentaron sentimientos de preocupación e incertidumbre sobre sus competencias digitales, que fueron disminuyendo en el transcurso del aislamiento y a partir de procesos de autoformación, aunque con poco apoyo de las instituciones y con limitaciones en el acceso a herramientas y recursos. Se evidenció la puesta en juego de competencias informacionales para el acceso y selección de recursos educativos digitales, así como competencias de comunicación y colaboración para mantener la interacción con los alumnos y familias. También, se observó que el uso frecuente de tecnologías no es una condición suficiente para su empleo intencional y crítico en procesos de enseñanza y aprendizaje. Por ello, se requiere de una formación sistemática y acompañamiento a los docentes en el desarrollo de sus competencias digitales.

Published: March 2024

Few studies have examined how fertilizers affect soil chemical properties, cabbage (Brassica oleracea L.) yield, and nutrient uptake in Ghana. This study examined how corn cob biochar (CCB) and NPK (15:15:15) fertilizer affected cabbage growth, yield, soil chemical properties, and nutrient uptake. The study was conducted during the 2021 major season at Soil Research Institute, Kwadaso. A 3×3 factorial experiment set out in a Randomized Complete Block Design with three replications was conducted. The treatments applied were control (No fertilizer), 50% NPK, 100% NPK, 2,500 kg ha-1 CCB, 50% NPK + 2,500 kg ha-1 CCB, 100% NPK + 2,500 kg ha-1 CCB, 5,000 kg ha-1 CCB, 50% NPK + 5,000 kg ha-1 CCB and 100% NPK + 5,000 kg ha-1 CCB. Application of 100% NPK resulted in the largest (2.99 cm) stem diameter. Application of 100% NPK + 5,000 kg ha-1 CCB resulted in the tallest plants (42.3 cm) and cabbage leaf spread (71.23 cm). Application of 100% NPK + 5,000 kg ha-1 CCB resulted in the largest cabbage head circumference (67.43 cm). The 100% NPK + 2,500 kg ha-1 CCB gave the highest yield (40679 kg ha-1). 100% NPK + 2,500 kg ha-1 CCB increased nitrogen uptake, 50% NPK + 5,000 kg ha-1 increased phosphorus and calcium uptake, 100% NPK + 5,000 kg increased potassium uptake, and 50% NPK + 2,500 kg increased magnesium uptake. Therefore, it is suggested that CCB and NPK fertilizers be applied to enhance the soil’s physical and chemical properties, nutrient uptake, and other factors contributing to cabbage growth and yield.

Plataformización de la Educación Pública: Propuestas para abordar las Desigualdades Socio-Digitales y Reforzar el Rol de la Administración Pública en Cataluña
Authors: Jacovkis Judith , Rivera-Vargas Pablo , Helsper Ellen Johanna
Published: March 2024

Las desigualdades socio-digitales tienen múltiples expresiones. La investigación en este campo muestra que distintos grupos sociales usan y aprenden a través de tecnologías digitales informalmente, emulando lo que ven en sus contextos sociales inmediatos. Al mismo tiempo, las tecnologías digitales se desarrollan y distribuyen desde posiciones deterministas, reduciendo el margen de reflexión sobre sus usos y limitaciones. Este artículo reflexiona acerca de las desigualdades socio-digitales relacionadas con el proceso de plataformización de la educación pública en Cataluña. El análisis se basa en una investigación mixta desarrollada durante 2022 que incluyó entrevistas con expertos y expertas y direcciones de escuelas e institutos, grupos de discusión con docentes, grupos de discusión con alumnado, y un cuestionario dirigido a familias de alumnado en educación obligatoria. Los resultados alertan sobre varios aspectos que pueden limitar el principio de equidad en la implementación de las plataformas digitales en educación. También nos permiten elaborar recomendaciones orientadas a reforzar el rol de la administración pública en este proceso.
Remedying Horizontal Inequality: The Changing Impact of Reform in Northern Ireland
Authors: Todd Jennifer
Published: March 2024

Northern Ireland is a case that lets us explore how people respond when deep‐set horizontal inequality is substantively reduced. This article focusses on the reform of horizontal inequality in the cultural sphere and argues that it is likely to be contentious because units and measures are directly related to conflicting constructs of group identity, meaning, and value, and intertwined with conflict over state legitimacy. Northern Ireland shows when and how this becomes politically problematic. The article traces an uneven but largely successful process of economic and political reform, followed by a reversal in the second decade of the 21st century, when unionist unease with cultural equality was reframed into political opposition which at times threatened the stability of the settlement itself. The backlash came when it did because of a confluence of processes: a particularly inappropriate presentation of cultural equality, at a time when the momentum of the peace process was coming to an end, and other opportunities, in particular for the Protestant working class, were closing. The case suggests the need to develop a conception of cultural (in)equality that is attuned to the asymmetric and contested constructions of “groupness” well before backlash occurs.
Sociological Types of Precarity Among Gig Workers: Lived Experiences of Food Delivery Workers in Riga
Authors: Ķešāne Iveta , Spuriņa Maija
Published: March 2024

In this article, we examine the lived experiences of precariousness in gig work, a growing sector of the modern labor market, through the case of Latvia, a former Soviet republic that has experienced radical neo‐liberalization over the last 30 years. Many studies, mainly focusing on the Global North, have demonstrated precarious aspects of gig work—its short‐term engagements, the lack of legal protection and social benefits, and algorithmic management as an autonomy‐limiting control mechanism. Given the precarious nature of gig work, we examine why people engage in it. Building on literature that distinguishes precarity as a condition and precariousness as a subjective experience, we analyze reasons for engaging in gig work in Latvia. We identify five types of gig workers based on 56 in‐depth interviews with food delivery gig workers in Riga, the capital of Latvia. We analyze differences in our respondents’ motivations for choosing this work, their position, and historical mobility in the social structure. Based on this analysis, we find three factors that serve as a basis for a typology of food delivery workers in Riga: gig workers’ view of gig work as a temporary vs. a long‐term engagement, the breadth of perceived opportunities available, and their emotional satisfaction with the job. We discuss how these findings compare with other studies on gig work and gig workers’ subjective experiences.

Authors: ÖZDOĞAN Havva , ÇEVİK Sonay
Published: March 2024

Kentsel odak mekânı kavramı toplumsal yaşam ve yerleşme kültürüne bağlı olarak farklılaşabilmektedir. Kentsel dokunun ana belirleyicilerinden olan sokaklar, sokakların morfolojik yapıları ve birbirleriyle ilişkileri, kesişme-buluşma biçimleri kentsel odak mekanlarının biçimsel yapılarını etkileyebilmektedir. Yerleşmeler planlı ve plansız olarak sınıflandırıldığında plansız yerleşmelerin tekrarlanmayan kendine özgü biçimlenmeleriyle planlı yerleşmelerden farklılaştıkları görülmektedir. Çalışma “yerleşme alanı – yerleşme alanlarındaki odak noktaları – yerleşme alanlarındaki odak noktalarının görsel odakları” arasındaki hiyerarşik yapı üzerine kurgulanmakta, geleneksel Anadolu yerleşmelerdeki sokak kesişim sistemleriyle oluşan sokak mekanları ve meydanlar kapsamında yürütülmektedir. Bu kapsamda kentsel toplanma mekanlarına ait tipolojik ve morfolojik yapının ortaya konması, toplanma mekanlarında mekân dizimi visibility (görülebilirlik) analiziyle görsel odak noktalarının ortaya konması ve sokak sistemleri ile aralarındaki ilişkiler, görsel odak noktalarının kentsel mekânda bulunma biçimlerine bağlı tipolojiler, sokak sisteminin değişimiyle görsel odak noktalarında ortaya çıkan değişikliklere ait morfolojik seriler irdelenmektedir. Çalışma kapsamında sokak eksenlerinin kesişme noktalarının/bölgeleri ile mekan dizimi yöntemiyle elde edilen görsel odak noktalarının birbirine benzer oldukları, sokak mekanlarındaki görsel odaklarının sokak mekanını çevreleyen düşey düzlemlerin tek kenarında, meydanlardaki görsel odak noktalarının meydanı çevreleyen düşey düzlemlerin iki kenarında yoğunlaştıkları görülmekte, bu durumun dinamik-sokak ve statik-meydan doğal yapısının bir sonucu olarak ortaya çıktığı değerlendirilmektedir.

Предложен метод оценки поперечного спин-холловского сопротивления для поликристаллических образцов чистых металлов. Вычислены коэффициенты спинового эффекта Холла для различных металлов 3 – 6 периодов, включая редкоземельные лантаноиды. Показано, что знак рассчитанного спин-холловского сопротивления всегда совпадает с экспериментальным. Для большинства рассмотренных металлов результат расчета согласуется с экспериментальными данными. Показано, что согласование результатов расчета с экспериментом можно значительно улучшить, если использованные приближения сильной связи и эффективного заряда дополнить предположением, что взаимодействие коллективизированных электронов проводимости при построении самосогласованного поля может быть учтено введением эффективной массы электрона проводимости в гамильтониан спин-орбитального взаимодействия. Обсуждены причины отклонения для алюминия, меди, диспрозия, гольмия и гадолиния.

Constraining Between-Event Variability of Kinematic Rupture Scenarios by Empirical Ground-Motion Model: A Case Study in Central Italy
Authors: Čejka František , Sgobba Sara , Pacor Francesca , Felicetta Chiara , Valentová Ľubica , Gallovič František
Published: March 2024

The region of central Italy is well known for its moderate-to-large earthquakes. Events such as 2016 Mw 6.2 Amatrice, generated in the shallow extensional tectonic regime, motivate numerical simulations to gain insights into source-related ground-motion complexities. We utilize a hybrid integral–composite kinematic rupture model by Gallovič and Brokešová (2007) to predict ground motions for other hypothetical Amatrice fault rupture scenarios (scenario events). The synthetic seismograms are computed in 1D crustal velocity models, including region-specific 1D profiles for selected stations up to 10 Hz. We create more than ten thousand rupture scenarios by varying source parameters. The resulting distributions of synthetic spectral accelerations at periods 0.2–2 s agree with the empirical nonergodic ground-motion model of Sgobba et al. (2021) for central Italy in terms of the mean and total variability. However, statistical mixed-effect analysis of the residuals indicates that the between-event variability of the scenarios exceeds the empirical one significantly. We quantify the role of source model parameters in the modeling and demonstrate the pivotal role of the so-called stress parameter that controls high-frequency radiation. We propose restricting the scenario variability to keep the between-event variability within the empirical value. The presented validation of the scenario variability can be generally utilized in scenario modeling for more realistic physics-based seismic hazard assessment.

The distinctive feature of cephalopods is their lack of scales, possession of eight arms and two long tentacles, with considerable diversity in shape, size, and habitat. Giant and colossal squids represent some of the largest marine creatures. Giant squids, in particular, are exceptionally captivating beings with unique characteristics that allow them to thrive in the incredibly dark depths of the oceans. Despite their large size, these cephalopods are agile swimmers, capable of sudden changes in direction. Vision is the primary sense for cephalopods, enabling them to perform these rapid movements. The giant squid (Architeuthis) has the largest eyes among marine and terrestrial animals, constituting a significant percentage of its weight and volume. These large eyes have captured the attention of biologists, leading to investigations into the anatomy, physiology, and histology of the cephalopod eye. It is noteworthy that the highest concentration of neural cells in the brain is found in the optic lobes of the giant squid, emphasizing the importance of vision in its life in dark and formidable habitats. In this review, we delve into the evolution, histology, structure, and physiology of the giant squid’s vision, followed by a comparative analysis with human optics.

In Kazakhstan, breast cancer (BC) remains the leading cause of cancer morbidity and mortality among women. The presented case series aims to summarize cardiovascular events that resulted in anthracycline-based chemotherapy discontinuation or suspension during the ongoing project on studying the cardiotoxicity effects. Case 1. Classic acute cardiotoxicity with asystole. Patient Sh., 46 years old, was admitted with a baseline LVEF of 64% and GLS of 22.4%. After the first dose of doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2, the patient experienced two episodes of asystole. She was prescribed Trimetazidine at a dose of 80 mg. Eventually, Sh. completed the courses of anthracycline therapy after a 1-month delay at a cumulative dose of 455 mg/m2. Case 2. Subacute cardiotoxicity with ventricular extrasystole. Patient Zh., aged 47, developed single, paired, and group ventricular extrasystoles after the 2nd course of chemotherapy with doxorubicin 200 mg/m2 (23 days after admission). Carvedilol was prescribed at 25 mg twice daily and Trimetazidine at 80 mg once a day. After 1 month of monitoring, ventricular extrasystoles disappeared. With a month’s delay, the patient completed chemotherapy at a cumulative dose of 400 mg/m2. Case 3. Severe cardiotoxicity due to pre-existing cardiovascular disease with discontinuation of chemotherapy. Patient M., aged 58, was referred to the very highrisk group for developed atrial fibrillation and heart failure with LVEF 51%. M. received Enalapril 5 mg two times per day, Bisoprolol 5 mg, Eplerenone 50 mg, Dapagliflozin 10 mg, and Dabigatran 150 mg twice daily. After 3 months, anthracycline therapy was canceled at a cumulative dose of 260 mg/m2 due to the deterioration of the patient’s condition (LVEF 41%.). Discontinuation or the delay of vitally needed chemotherapy in BC patients deteriorate their prognosis for survival. Patients should be constantly monitored during and after anticancer treatment.

Gender-based learning has been implemented in the study of Islamic jurisprudence (fikih). The role of the boarding school in the development of this separation is deemed effective, as evidenced by the achievements in personal and environmental development.
The Mediating Role of Learning Analytics
Authors: Villalobos Díaz Esteban , Hilliger Isabel , Gonzalez Carlos , Celis Sergio , Pérez-Sanagustín Mar , Broisin Julien
Published: March 2024

Researchers in learning analytics have created indicators with learners’ trace data as a proxy for studying learner behaviour in a college course. Student Approaches to Learning (SAL) is one of the theories used to explain these behaviours, distinguishing between deep, surface, and organized study. In Latin America, researchers have demonstrated that organized approaches to learning could be more effective in higher education, leading to better performance and course approval. However, further analysis of student behavioural data is needed to understand this relationship and inform interventions targeting study habits and academic performance. In this study, we analyzed the relationship between student approaches to learning and their final grade in six college courses, using behavioural trace data as a mediator variable. Specifically, we conducted a quantitative study in two Latin American institutions where data of different granularity was collected from their Learning Management Systems. We observed that most learning analytics indicators do not mediate the effect between approaches to learning and course performance. However, there was evidence for fine-grained indicators acting as total mediators. Implications are discussed at methodological and pedagogical levels, aiming to inform the advancement of learning analytics in the region and its use for supporting student learning.

Investigations were carried out to characterize twenty maize inbreds at biochemical levels among QPM and normal maize lines for their effective utilization in the breeding program. Proximate analysis was carried out to study the nutritional quality of maize inbred lines based on lysine and tryptophan levels among the two groups. The nutritional composition includes lysine, tryptophan, moisture, oil, crude protein, starch and total soluble sugars, showing significant differences between QPM and normal maize inbreds, while fibre and total ash content showed little variation. Phytonutrients showed slightly higher value for QPM lines compare to normal lines exhibiting good antioxidant capability of QPM lines. The present investigation highlights the importance of evaluating biochemical parameters when selecting parents for crossing programs. The proximate composition and antioxidant capacity were proved to be useful for nutritionally better varietal identification and to evaluate QPM and normal maize lines based on nutritional and antioxidant performance.

The present study was designed to study the effect of two different seasons (summer and rainy) on the activities of some oxidative stress markers (SOD, GSHPx and MDA) in Deccani sheep. The experiment was carried out at the Department of Veterinary Physiology, KNP College of Veterinary Science, and Shirwal. Dist. Satara on eight apparently healthy, non-pregnant, non-lactating Deccani sheep above two years of age maintained under semi-intensive housing conditions at Livestock Farm Complex, KNP College of Veterinary Science, Shirwal, Dist. Satara. The meteorological data recorded during the present study were obtained from the Indian Meteorological Department, Pune. The monthly calculated mean values of THI during the study period revealed significantly (P < 0.01) higher THI during Summer (77.81 ± 0.19) than in the Rainy season (74.92 ± 0.16). In the present study, the mean plasma activity of SOD was significantly (P < 0.01) higher during the summer season (510.93 ± 24.77 U/ ml) than in the rainy season (436.58 ± 26.30 U/ ml). The mean erythrocyte activity of glutathione peroxidase showed significantly (P < 0.05) higher values in the summer season than in the rainy season (102.12 ± 5.03 U/gHb and 85.63 ± 3.89 U/gHb). The mean plasma levels of MDA were significantly (P < 0.01) higher during the summer season (5.29± 0.09 nmol/ml ) than in the rainy season (3.27± 0.09 nmol/ml). The finding indicates that oxidative stress markers like SOD, GSHPx and MDA could be used as a sensitive biomarker of oxidative stress caused due to heat stress in Deccani sheep.

Authors: Vijayvargiya Vishal , Singh Gurpreet
Published: March 2024

Background: The research aims to enhance fruit quality and production of the Dashehari mango variety through micronutrient treatments in Rajasthan, India. Micronutrients play a crucial role in plant growth and development and their deficiency can lead to suboptimal yields and reduced fruit quality. This study seeks to investigate the effects of micronutrient application on mango trees, particularly focusing on the Dashehari variety, to improve both the quantity and quality of mango production. By understanding the impact of micronutrient treatments, the research aims to provide valuable insights into sustainable agricultural practices that can optimize mango cultivation and contribute to increased agricultural productivity. Methods: The research administered borax, ferrous sulphate and zinc sulphate to soil and trees in 10 treatments. The soil of an 18-year-old mango variety named Dashehari was treated in the first week of October with foliar sprays throughout the flower bud initiation, full bloom and pea stage initiation stages. A three-replication randomized block design was employed for the investigation. Result: The results show that the treatment known as “T9”-Application of borax to the soil in the amount of 125 grams, followed by the application of borax to the foliar in the amount of 0.2 per cent-produced the highest quality and quantity of mango fruit. Additionally, treatments of soil application of ZnSO4 per tree 125 g, followed by foliar application of ZnSO4 0.4% and soil application of FeSO4 per tree 125 g, followed by foliar application of FeSO4 0.4%, also showed promising results.
Effect of Mulches on Crop, Soil and Water Productivity: A Review
Authors: Verma Sudhanshu , Pradhan Swati Swayamprabha
Published: March 2024

A mulch is a layer of material applied to the surface of an area of soil. Mulches are used for various reasons in agriculture but water conservation and erosion control are the most important objectives particularly in arid and semi-arid regions. Other reasons for use of mulching include soil temperature modification, weed control, soil conservation and after decomposition of organic mulch add plant nutrients, improvement in soil structure, increase crop quality and yield. Conservation of soil moisture by application of mulches becomes essential for profitable cultivation of the crop under rainfed condition of semi-arid ecosystem. In spite of no assured irrigation in these regions, the moisture conservation technique is not in practice. Mulches not only conserve soil moisture but also impart manifold beneficial effects, like suppression of extreme fluctuation of soil temperature and reduction of water loss through evaporation, resulting in more stored soil moisture, maintenance of soil fertility, suppression of weed growth, improvement in growth and yield. The requirement of water through mulch can further be reduced by using locally available organic materials as mulches which not only save irrigation water but also conserves soil moisture.

Published: March 2024

Background: In most developing countries poultry farming is owned by small business owners, farmers and their families. The broiler industry has fewer climate restrictions and more adaptability and in this sector entrepreneurial activities are still unexplored in India. The purpose of this study was to look into the production performance, income and employment generation of broiler production in Morena district of M.P. Methods: The broiler farms of the Morena district were identified with the help of Veterinary department personnel, commercial hatchery persons and poultry feed manufacturers and a list of 50 farms, was prepared. The list was arranged in the ascending order of the number of birds kept on a farm. From this list, 30 such farms were selected that were continuously in production for at least one year and where proper records were maintained. The list was divided into three categories based upon the number of birds viz. small farm group (below 1999 birds), medium farm group (2000 to 4999 birds) and large farm group (5000 and above birds). 5 farms were selected randomly from each farm category. Information was gathered by visiting selected chicken farms and interviewing the owners using a prepared questionnaire. The research study was conducted under the Department of A.H. and Dairying, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj (U.P.). The data were collected for the duration 2019-20. Results: The present study documented the mean feed conversion ratio, mean Livability percent, mean weight and age at marketing of broilers as 1.83, 95.82 percent, 2.38 kg and 43.8 days respectively for sample as a whole. The average total cost per bird was Rs 161.35. The gross return and net return per bird is found as Rs 185.27 and Rs 23.92 respectively. The benefit-cost ratio is worked out to be 1.15 for the sample as a whole. Rs 6.84 is spent on labour per bird in one production cycle of 56 days. Thus Rs 65664 per farm is spent on employment of labour in 56 days. On the basis of 8 hours working, 3.43 persons have been employed per farm. The statistical analysis using ANOVA found that there is a significant relationship between income and farm size, BCR and farm size.

Background: Green gram is an important pulse crop known for its nutritive values as a rich source of protein and high culinary application in Indian dietary system. However, like any other crop, it faces the challenge of weed competition, which can significantly reduce its yield and quality. The objective of this study was to determine the best suitable weed management practices for green gram. Methods: Field experiment was conducted during summer season of 2021 at School of Agricultural Sciences, Nagaland University, Medziphema Campus. There were seven weed management treatments and one treatment kept as control. All treatments were replicated thrice. Result: Hand weeding at 20 and 40DAS showed greater weed control and recorded higher values in growth and yield and showed at par values with other weed management practices pre-emergence application of pendimethalin fb hand weeding at 20 DAS, Pendimethalin @ 0.75 kg ha-1 (PE) fb Rice straw mulching @ 5 t ha-1, Imazethapyr @ 0.5 kg ha-1 (PoE) at 15 DAS fb Quizalofop p-ethyl @ 0.15 kg ha-1 (PoE) at 30 DAS and Pendimethalin @ 0.75 kg ha-1 (PE) fb Quizalofop p-ethyl @ 0.15 kg ha-1 (PoE) at 30 DAS. However, the use of only rice straw could not perform better. This indicates the advantages of integration of weed management practices. With hand weeding a laborious task concerning in large field condition, other integration of weed management will serve a viable option for profitable weed management in green gram.
Truth-Telling, Aging, and Healing From Institutional Psychiatric Violence: A Life Story and Mad Studies Perspective
Authors: Punzi Elisabeth , Bergstrand Gunnel
Published: March 2024

During the last decades of the 20th century, large-scale psychiatric institutions were dismantled. This “deinstitutionalization” was connected to efforts to end institutional violence. Former inmates, however, had institutional violence inscribed into their bodies and souls. This article is written by one of them, 87-year-old Swedish psychiatry survivor, Gunnel Bergstrand, together with researcher Elisabeth Punzi. They explore how Gunnel’s stay at a dismantled Swedish psychiatric institution in 1956 affected her whole life and how she struggled to find a listener. We frame our work in a life story perspective and in the recently developed discipline of Mad studies, which challenges psychiatric terminologies and interventions and reclaims expertise based on the knowledge of those with lived experiences, past and present.
Zen and the Art of MoodCycle Maintenance
Authors: Healy David
Published: March 2024

Depression was slow to come to Japan. Selective serotonin reuptake inhibitors (SSRIs) were licensed there a decade later than in the West. Once licensed, the use of antidepressants escalated rapidly. There is now talk of a mental health crisis in children and adolescents in both West and East, in which a younger generation seems to have lost its bearing, and psychotropic drug use in this age group in particular is now rampant despite minimal evidence for effectiveness. A Zen approach to life was slow to come to the West. Meditation in the form of mindfulness arrived in the United States just before the SSRIs arrived in Japan. Mindfulness, as practiced in the West, shows features of commodification that are antithetical to the “spirit” of Zen. The marketing of both SSRIs and mindfulness points to a commodification of techniques that are at odds with the spirit of science. They also point to an encephalization in the way we view ourselves and our problems that may be getting in the way of us seeing how both drugs and meditation are actually acting.
