Educar desde, en y para la libertad. Un análisis desde la historia de la educación y la filosofía personalista
Authors: Martínez-Carbonell López Alfonso
Published: September 2024

El objetivo del presente trabajo consiste en demostrar la in- disolubilidad entre educación y libertad desde una perspectiva histórica y filosófico-personalista. Desde una visión histórica, educación y libertad han estado íntimamente vinculadas, hasta el punto de afirmar que no existe ver- dadera educación de la persona si no es desde, en y para la libertad. Anali- zamos tres momentos sublimes en la historia de la educación: el nacimiento de la escuela en la Grecia clásica; la aportación educativa del cristianismo de la libertad interior; y el surgimiento de las universidades en la Edad Media como corporaciones libres de maestros y escolares. A continuación, apor- tamos la reflexión filosófico-personalista sobre la libertad en el encuentro educativo. Antes y al inicio, como impulso vocacional del maestro e impulso interior y espiritual del discípulo a hacerse. Durante, mediante el método dialéctico, el acompañamiento y la relación de confianza entre ambos. Y, al final del encuentro, como culmen del proceso de personalización formando la libertad del educando para que sepa elegir, desde su centro interior, aque- llo que le construye como persona en medio de las circunstancias y realida- des concretas en que se desarrolla su existencia. En esta parte se han tenido en cuenta las reflexiones filosóficas y pedagógicas de autores personalistas, como Mounier, Guardini, Buber, Stefanini, Zubiri y López Quintás.
La libertad en los nuevos entornos educativos: Competencia Tecnológica y Educación Integral
Authors: Savall Mata Miguel Miguel Ángel , Serrano Pelegrí Fernando
Published: September 2024

Con el acceso universal a la tecnología, los sistemas educati- vos se han visto obligados a diseñar programas específicos para desarrollar las habilidades necesarias para un correcto uso dentro y fuera de las aulas. El alumnado vive inmerso en tecnología y el desarrollo pleno de una competencia digital completa toma protagonismo. El nuevo paradigma tecnológico contempla el concepto de identidad digital, vinculado a los usos comunicativos y sociales de los individuos, tanto en el ámbito personal como profesional. Tecnología y persona no son elementos antagónicos. Más allá del dominio de la tecnología y la información, se plantea la necesidad de aunar elementos fundamentales en la educación tales como la ética y la moral, imprescindibles en la nueva Sociedad de la Información para alcanzar la verdadera libertad, el desarrollo espiritual del individuo mediante itinerarios curriculares adecuados. La competencia digital se presenta como medio idóneo para alcanzar otras competencias esenciales de cara a su desarrollo como individuo único plenamente integrado en una sociedad.
La ecología del cuerpo humano: Ser cuerpo, tener cuerpo, estar en el cuerpo
Authors: Malo Antonio
Published: September 2024

A pesar de la analogía del cuerpo humano con el del animal,entre ellos hay una diferencia esencial: el cuerpo del animal no trasciende la propia especie, mientras que el humano va siempre más allá, pues espersonal, no reductible al simple individuo de la especie. Por eso, la visiónanimal del cuerpo humano no permite captar que la persona tiene una triplerelación con el propio cuerpo: ella es cuerpo, lo tiene y está en él. La falta decomprensión de esta triple relación no solo conduce a una mala interpretación de una serie de fenómenos antropológicos (el carácter sexuado de laspersonas, la técnica, la afectividad humana y las relaciones interpersonales),sino también a modos ecológicos equivocados de relacionarse con los demásy con el propio cuerpo.
Update on the Use of Dexamethasone Injection After Third Molar Odontectomy: A Systematic Review
Authors: Andriansyah  , Abul Fauzi  , Eka Prasetiawaty
Published: September 2024

Postoperative complications of extracting impacted third molar teeth often include pain, trismus, and facial swelling. Recent studies have explored the application of dexamethasone to lessen this inflammation following surgery. We used a systematic review and meta-analysis in this investigation to assess the efficacy of dexamethasone. in reducing postoperative complications. Article searches were conducted using PRISMA guidelines in four electronic databases: Web of Science, PubMed, Embase, and Google Scholar. The keywords were selected according to the data search strategy. The PICO framework (Population, Intervention, Comparison, Outcome) was used to organize this systematic review and using SIGN (Scottish Intercollegiate Guidelines Network) bias assessment. The study used a visual analog scale to assess postoperative pain. The dose of dexamethasone used varied between 8 mg, 1 ml intravenously and 0.3 mg/kg. The results showed variations in the duration of analgesic use and the number of analgesic tablets required. Overall, the use of dexamethasone after third molar surgery was shown to reduce edema and trismus. However, the response to pain reduction was variable. This study concludes that intramuscular, pterygomandibular injection, sublingual, and submucosal administration of dexamethasone can produce better therapeutic effects than conventional postoperative care for extraction of impacted third molar teeth. In particular, During the healing phase swelling, trismus and edema are significantly reduced
Why the Arab World Needs Community Radio
Authors: Kuttab Daoud
Published: September 2024

Despite the ongoing debates about cause and effect, the protest movements that began in Tunisia and spread throughout the Arab world have had one clear vehicle: freedom of assembly and expression. The crowds of Arab youth who have assembled in cities, towns and villages have forced authoritarian rulers to recognize them, their right to protest the status quo and their right to demand change. While in some countries winning this right has been accomplished relatively easily and quickly, in other countries it has been difficult, dangerous and deadly. Yet the protesters have continued to demand the right to voice their grievances against the powers-that-be. While the protests and mass expression of demands have taken place largely using traditional means (e.g. word-of-mouth, demonstrations, marches and sit-ins, all broadcast via satellite television channels), like all revolutions, we have seen an explosion of creative ideas that have leveraged creative solutions. From the use of colorful graffiti in Libya to new and social media in Egypt and Syria, young Arabs have been busy making their voices heard through a variety of new platforms. Yet one tool that has escaped the majority of Arab protesters has been radio.
A Proposal for a Dialogue on Media Reform
Authors: Ghozlan Mahmoud
Published: September 2024

I would like to start by saying that this proposal is no more than a personal initiative on my part and should not be attributed to the Muslim Brotherhood or to the Freedom and Justice Party, since I have not discussed it with anyone from those organizations.[1] It is a call for a society-wide dialogue on this serious subject, especially within media circles—experts, academics and prominent figures—in the hope of enriching and complementing the proposal, or changing and replacing it. What matters is that the stagnant waters should move and that bright ideas should cross-pollinate. God knows, my only aim in making this proposal is the best interests of this large and vital sector which helps to shape the way people think, steers public opinion and thus defines policies and actions.
Repetition and Ideology in Nasrallah’s Political Speeches
Authors: Lahlali El Mustapha
Published: September 2024

This paper examines the ideological function of lexical repetition in Hassan Nasrallah’s speeches. The frequency of repetition in Arabic has long been explored in terms of its various formalistic approaches. However, little or no focus has been placed on the relationship between repetition and ideology. This paper argues that repetition is deliberately used to reinforce Nasrallah’s different political strategies, which have been devised to address various Lebanese groups and factions. The paper also argues that the speaker has used different discourse registers to address various audiences. The prevalence of lexical repetition has been deliberately employed in Nasrallah’s speeches to promote his ideological and political stance.
Twitter and Tyrants: New Media and its Effects on Sovereignty in the Middle East
Authors: Lamer Wiebke
Published: September 2024

There was no shortage of reporting on the role of new media, in particular social networking media, during the revolutions that spread throughout the Middle East starting in Tunisia in December 2010, leading to the ousting of Tunisian president Zine El Abidine Ben Ali, Egyptian president Hosni Mubarak, Muammar Gaddafi in Libya, and are ongoing in other countries of the region. Dubbed the Facebook, Twitter, and/or YouTube Revolutions by commentators, one might be forgiven for believing that these new forms of media might have caused the events that we have seen unfolding since late 2010. Such characterizations, however, take away from the true causes of the uprisings: the yearning, among hundreds of thousands, if not millions, of Arabs for human dignity and freedom from economic and social ills and political oppression. Thousands of Egyptians finally had had enough and they were prepared to die for their cause. Media can play a role in such movements, but it is highly doubtful that they can cause them. It takes more than a call to join a flash mob via Facebook to get people to participate in protests, fully aware that they could pay with their lives. The following sentence summarizes the role of the media in the Arab Spring, with regard to Egypt: “Mubarak provided the grievances, Tunisia gave the inspiration, Facebook set the date, and the Egyptian people did the rest. The role of the media in the Arab Spring can primarily be defined as providing a tool, not the cause for the political movement.

Published: September 2024

Sustainable environmental practices and food production depend heavily on agricultural techniques. This study aimed to determine the extent to which local farmers adopt sustainable agriculture and to design an agroecological model to support this approach. A non-experimental descriptive correlational research approach was used, involving 70 local farmers in Region VII, Central Visayas. Probability simple random sampling was employed to select participants who engaged in farming practices. The statistical tools used included frequency counts, percentages, weighted means, and the chi-square test of independence. The findings revealed that agricultural practices among the local farmers significantly contributed to achieving sustainable agricultural production in terms of environmental quality. However, these practices were moderately extensive concerning economic sustainability and social viability. Additionally, a significant relationship was found between the extent of adoption of agricultural practices and farmers’ perceptions of these practices’ contributions to agricultural sustainability, including economic sustainability, social viability, and environmental quality. The study concluded that these agricultural methods provided the local farmers with food security, enhanced social welfare, and, to some extent, improved environmental quality. Sustainability and resilience hinge on the collaboration between farmers within the community and the support of both public and private sectors through adequate financial and agricultural mechanisms.

Imagery Rehearsal Therapy and mianserin for trauma-affected refugees
Authors: Nielsen Anders , Klich Felix , Poulsen Stig Bernt , Carlsson Jessica , Sandahl Hinuga
Published: September 2024

Introduction:
In order to identify the efficacy of treatment interventions for trauma-affected refugees follow-up studies are highly warranted. Hence, the overall aim of this study was to examine the efficacy of sleep-enhancing treatment, IRT and mianserin, in a sample of 219 trauma-affected refugees at six-month follow-up post-treatment.
Methods
Data were derived from a four-armed randomized controlled trial in a sample of trauma-affected refugees with PTSD. All four arms received Treatment as Usual (TAU), an interdisciplinary treatment approach: one group received solely TAU, serving as a control group, whereas the remaining three groups were active-treatment groups receiving add-on treatment with either IRT, mianserin, or a combination.
Mixed models were used to analyze the combinations of the two treatment factors (IRT vs. non-IRT and mianserin vs non-mianserin) and time (baseline vs follow-up and post-treatment vs follow-up) for the primary outcome sleep quality and for several secondary outcome measures.
Results
A total of 36.7% of the participants had been exposed to torture and 44% had been imprisoned.
The only significant effect of IRT was on well-being (measured with WHO-5), where IRT showed higher improvement in well-being six months post-treatment (p = .027). There was no significant effect of mianserin on any of the outcome measures.
Discussion
This follow-up study found improvements from baseline to post-treatment on sleep quality and most of the secondary outcome measures that were maintained for all treatment conditions at the six-month follow-up assessment. A limitation of the study was that a high proportion (53.4%) of the participants did not attend the follow-up evaluation.
The results indicate that add-on IRT-treatment and add-on mianserin-treatment were not superior to TAU at six-month follow-up post-treatment.

Elucidating the kinetic and thermodynamic insight into regulation of glycolysis by lactate dehydrogenase and its impact on tricarboxylic acid cycle and oxidative phosphorylation in cancer cells
Authors: Zeng Siying , Wang Yuqi , Ying Minfeng , Jin Chengmeng , Ying Chang , Wang Di , Wu Hao , Hu Xun
Published: September 2024

Lactate dehydrogenase (LDH) stands at the intersection of pyruvate metabolism. While it is believed that inhibition of LDH redirects pyruvate to mitochondrial metabolism, suppressing glycolysis and boosting oxidative phosphorylation, the mechanism remains largely unexplored. We found that individual LDH A or B knockouts had minimal impact on glycolysis, tricarboxylic acid cycle (TCAC), or oxidative phosphorylation (OXPHOS). However, combining LDH knockout with LDH inhibitor GNE-140 significantly suppressed these processes. Inhibition of LDH led to an increase in free NADH concentration and a decrease in free NAD
+
concentration, the reduced free NAD
+
concentration inhibited GAPDH, disrupting the balance of glycolytic intermediates, which were linked with thermodynamic shift of the Gibbs free energy of reactions between phosphofructokinase 1 (PFK1) and phosphoglycerate mutase (PGAM) in the glycolytic pathway, favoring their reverse direction. This disrupted glycolysis led to impaired TCAC and mitochondrial respiration due to reduced pyruvate and glutamine carbon influx into TCAC. Under hypoxia, LDH inhibition had a stronger effect, inducing energy crisis, redox imbalance, and cancer cell death. Our study reveals LDH’s intricate control over glycolysis, TCAC, and mitochondrial respiration, highlighting the interplay of enzyme kinetics and thermodynamics in metabolic pathways—a crucial aspect for understanding metabolic regulation.

Published: September 2024

Oxygen bubbles that leak from seagrass blades during photosynthesis have been hypothesized to cause cavitation sounds in aquatic plants. Here we investigate low-amplitude sounds with regular pulse rates produced during photosynthesis in seagrass beds of Halophila ovalis (Qitou Bay, Penghu islands and Cigu Lagoon, Taiwan). Sound pulses appear in the morning when illumination exceeds 10,000 Lux, peak at midday and decrease in midafternoon on a sunny day. Frequencies peak between 1 to 4 kHz, durations range between ca. 1.8 to 4.8 ms, and sound pressure level 1 cm from the bed is 105.4 ± 0.5 dB re 1 μPa (1100 h on a cloudy day). Sounds attenuate rapidly with distance, disappearing beyond 15 cm. Blocking sunlight or administering herbicide stops ongoing sounds. Gas bubbles are not typically seen during sound production ruling out cavitation, and external force (scissor cutting or plant pressed against the substrate) applied to the patch, leaves, petioles, or rhizomes generally increases pulse rate. We suggest sound emission is caused by internal oxygen transport through pores in diaphragms (a whistle mechanism) at the leaf base and nodes of the rhizome.
Inversion model of soil salinity in alfalfa covered farmland based on sensitive variable selection and machine learning algorithms
Authors: Ma Hong , Zhao Wenju , Duan Weicheng , Ma Fangfang , Li Congcong , Li Zongli
Published: September 2024

Purpose

Timely and accurate monitoring of soil salinity content (SSC) is essential for precise irrigation management of large-scale farmland. Uncrewed aerial vehicle (UAV) low-altitude remote sensing with high spatial and temporal resolution provides a scientific and effective technical means for SSC monitoring. Many existing soil salinity inversion models have only been tested by a single variable selection method or machine learning algorithm, and the influence of variable selection method combined with machine learning algorithm on the accuracy of soil salinity inversion remain further studied.

Methods

Firstly, based on UAV multispectral remote sensing data, by extracting the spectral reflectance of each sampling point to construct 30 spectral indexes, and using the pearson correlation coefficient (PCC), gray relational analysis (GRA), variable projection importance (VIP), and support vector machine-recursive feature elimination (SVM-RFE) to screen spectral index and realize the selection of sensitive variables. Subsequently, screened and unscreened variables as model input independent variables, constructed 20 soil salinity inversion models based on the support vector machine regression (SVM), back propagation neural network (BPNN), extreme learning machine (ELM), and random forest (RF) machine learning algorithms, the aim is to explore the feasibility of different variable selection methods combined with machine learning algorithms in SSC inversion of crop-covered farmland. To evaluate the performance of the soil salinity inversion model, the determination coefficient (R2), root mean square error (RMSE) and performance deviation ratio (RPD) were used to evaluate the model performance, and determined the best variable selection method and soil salinity inversion model by taking alfalfa covered farmland in arid oasis irrigation areas of China as the research object.

Results

The variable selection combined with machine learning algorithm can significantly improve the accuracy of remote sensing inversion of soil salinity. The performance of the models has been improved markedly using the four variable selection methods, and the applicability varied among the four methods, the GRA variable selection method is suitable for SVM, BPNN, and ELM modeling, while the PCC method is suitable for RF modeling. The GRA-SVM is the best soil salinity inversion model in alfalfa cover farmland, with Rv2 of 0.8888, RMSEv of 0.1780, and RPD of 1.8115 based on the model verification dataset, and the spatial distribution map of soil salinity can truly reflect the degree of soil salinization in the study area.

Conclusion

Based on our findings, the variable selection combined with machine learning algorithm is an effective method to improve the accuracy of soil salinity remote sensing inversion, which provides a new approach for timely and accurate acquisition of crops covered farmland soil salinity information.
Los vicios periodísticos de corte patriarcal en los encuadres noticiosos sobre femicidios
Authors: Ingrassia Paola
Published: September 2024

Las noticias periodísticas ofrecen una visión particular del mundo a partir de estrategias discursivas que buscan plasmar sentidos específicos afines a los objetivos que persiguen. Así, lejos de las posiciones objetivistas, en este trabajo se subraya el rol de los/as periodistas como actores políticos (Borrat, 1999) que interpretan, recortan y enfatizan ciertos aspectos de una realidad percibida al momento de darla a conocer a sus audiencias (Entman, 2003). En esa línea, el objetivo es presentar una matriz para el análisis de los encuadres noticiosos sobre femicidios a partir de una triangulación teórico-metodológica que se considera innovadora para analizar las prácticas periodísticas específicas que refuerzan las visiones patriarcales en las noticias sobre esa problemática social. Además del desarrollo y de la fundamentación de las decisiones metodológicas, el instrumento se pone a prueba en el análisis de las 66 noticias sobre femicidios publicadas por dos medios de comunicación tradicionales en línea de Argentina, Clarín y Diario de Cuyo, durante 2019. Entre los resultados se destaca que los encuadres noticiosos sobre femicidios dan cuenta de las decisiones periodísticas que contribuyen a perpetuar el fenómeno estructural de las violencias de género y a reforzar el orden patriarcal, en lugar de interpelar a las audiencias y favorecer la acción disruptiva. Se advierte asimismo que las miradas que se ofrecen sobre las violencias contra las mujeres son superficiales y, por ende, las propuestas de solución resultan eminentemente vacías de sentido.
Análisis conceptual del propósito corporativo: sostenibilidad, RSC, ODS y comunicación
Authors: Barrio-Fraile Estrella , Enrique Ana María , Freire-Sánchez Alfonso , Vidal-Mestre Montserrat
Published: September 2024

Este artículo presenta una revisión sistemática de la literatura sobre el concepto de propósito corporativo (PC) y reflexiona sobre su relación con nociones como sostenibilidad, RSC, ODS y comunicación. La definición y la activación del PC en las empresas es una tendencia en la gestión actual de intangibles. Tras una búsqueda de artículos en Web of Science y Scopus, una vez aplicados los filtros correspondientes se analizan 50 artículos a partir de técnicas cuantitativas y cualitativas. Entre los hallazgos detectaron cinco ámbitos principales de conocimiento que estudian el PC (gobierno corporativo, gestión empresarial, derecho, economía y comunicación) y ocho criterios comunes en las diferentes definiciones aportadas. Asimismo, la discusión de los resultados permite concluir que, a diferencia de la estrecha relación entre el PC con la RSC y la sostenibilidad, la literatura que estudia su vinculación con los ODS es escasa, como también lo es aquella que estudia la forma de comunicar la razón de ser de una empresa y su narrativa social. Finalmente, se realiza una nueva definición de PC que busca unificar criterios y aportar cierta paridad ante un concepto que presenta múltiples interpretaciones y reflexiones.
Análisis de la productividad e impacto de la investigación en comunicación en España y América Latina (1980-2022)
Authors: Salvador - Mata Bertran
Published: September 2024

Este artículo examina la disciplina de la comunicación en los cinco países de habla hispana con la mayor producción científica en la Web of Science (WoS), por orden: España, Chile, México, Argentina y Colombia. Utiliza la herramienta de agrupación algorítmica citation topic (CT) de InCites (Clarivate Analytics) para generar agrupaciones únicas de trabajos científicos basados en sus relaciones de citación. A partir de este clúster original, se analizan diversos indicadores para evaluar el impacto, tales como citas/artículo, la proporción de artículos en SSCI versus ESCI y el cuartil. También se explora la evolución de la colaboración internacional y se desglosan los datos por universidades. España lidera en producción y revistas indexadas, perpetuando la hegemonía del Norte Global, aunque Chile presenta los mejores indicadores de impacto. México exhibe resultados intermedios, mientras que Colombia y Argentina se caracterizan por una producción e impacto relativamente bajos, a excepción del aumento en la colaboración internacional observado en Colombia. Se confirma que las redes científicas hispanohablantes, específicamente aquellas del Sur Global, se sitúan en la periferia de una plataforma restrictiva como es WoS. Finalmente, se sugieren varias estrategias para mejorar la situación, incluyendo la revisión de los índices de revistas, la reconceptualización de las políticas de investigación y la descolonización de la ciencia global, junto con establecer nuevos marcos de legitimación científica.

Authors: Reimão Gabriella Abib Martins , Beber Uiara Jones , Ribeiro Mateus Oliveira , Porcino Fernanda Rodrigues , Francischini Vitor Gabriel Silva , Almeida Carolina de Godoy
Published: September 2024

A obesidade é apresentada como uma doença crônica não transmissível, de origem multifatorial e com repercussão sistêmica. Os casos de obesidade infantil aumentaram com a pandemia mundial causada pela Covid-19. O  diagnóstico clínico  para  obesidade  infantil  ocorre  por  meio  da  anamnese,  dados  nutrológicos (anamnese  alimentar),  exame  físico  (peso,  altura,  IMC,  circunferência  abdominal)  e exames complementares. Esse trabalho tem o objetivo de realizar uma análise quantitativa e temporal sobre as características epidemiológicas da obesidade em crianças com idade de 1 a 14 anos no  período de Janeiro de 2013 a Dezembro de 2023. Metodologia: Trata-se   de   um   estudo epidemiológico  embasados a partir dos dados  do  departamento  de informação  de  saúde  do  SUS  (Sistema  Único  de  Saúde).  As  variáveis  utilizadas  foram:  internações  hospitalares, óbitos,  faixa  etária,  cor/raça,  sexo,  gastos  hospitalares  e  macrorregião  de saúde. Resultado: 1.021 internações ocorreram por obesidade. Ainda que a região Sul tenha sido a mais notificada quanto a quantidade de internações, a região Sudeste foi a região com maior númuro de óbitos por obesidade no país. A maior faixa-etária acometida foi entre 15 e 19 anos (Adolescentes jovens). O sexo feminino foi o gênero mais afetado por essa patologia. Em relação à etnia, mais pacientes brancos são internados. Conclusão: a realização destes estudos é essencial para o desenvolvimento de políticas públicas voltadas ao diagnóstico, tratamento e notificação adequada dos casos de obesidade infantil no país. Por tratar-se de um estudo baseado em dados secundários, algumas limitações se fazem presentes, portanto, mais estudos epidemiológicos devem ser conduzidos.

Published: September 2024

Objetivou-se, neste trabalho, analisar a influência dos conselheiros municipais no processo de tomada de decisões do Conselho Municipal de Assistência Social do Município de Lavras a partir da posse de recursos de natureza individual (escolaridade, renda, motivação para ação, etc.) e coletiva (organizacionais de ordem material, financeira, etc.). Para tal, utilizou-se a abordagem de pesquisa qualitativa, com a realização de Pesquisas de Campo e Documental. Para coleta de dados da pesquisa de campo o presente trabalho valeu-se de questionários e teve como alvo os Conselheiros Municipais do CMAS-Lavras. Na fase de Pesquisa Documental foram realizadas análise qualitativas com vistas a obter a elucidação do problema investigado. Constituíram objetivos deste trabalho a busca por elementos que evidenciassem possíveis relações entre a posse dos recursos citados acima e a capacidade daqueles atores de influenciar o processo deliberativo.

The investigation was carried out during the Kharif seasons of 2022 and 2023 at the Students' Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. To assess the impact of various nutrient management strategies, including Nano-Zn, inorganic, and organic methods, on the growth and yield of Kharif maize. A Split-Plot Experimental design was employed, incorporating three replications. Organic manures-specifically a control, farmyard manure (FYM) applied at 10 t/ha, and vermicompost applied at 5 t/ha-were assigned to the main plots. Meanwhile, nutrient management treatments (including a control, 75% RDF, 75% RDF + ZnSO4, 75% RDF + Nano-Zn, 100% RDF, 100% RDF + ZnSO4, and 100% RDF + Nano-Zn) were allocated to the sub-plots. The maize variety chosen for the study was DKC-9144. The soil at the experimental site was characterized by a sandy loam texture, with a pH ranging from 7.72 to 7.67, a bulk density of 1.37 Mg/m³, and organic carbon levels between 0.43% and 0.44%. The location of the site is within the Indo-Gangetic Plain, which is typified by a subtropical climate and an average annual rainfall of about 890 mm. Throughout the experiment, data were collected on key growth parameters such as the crop growth rate (CGR), relative growth rate (RGR), and absolute growth rate (AGR) at different stages of maize development (30-60 days after sowing, 60-90 days after sowing, and from 90 days after sowing until harvest). Results indicated that the treatment involving 100% RDF combined with Nano-Zn at 10 ml/litre produced the highest growth rates, while 100% RDF + ZnSO4 also showed significant results. Among the organic treatments, vermicompost at 5 t/ha proved to be more effective than FYM, highlighting the superior role of Nano-Zn and advanced nutrient management practices in promoting the growth and yield of Kharif maize.

A large number of mites infest mushroom fruiting body and compost. These mites cause enormous damage to the fruiting body. An effort was made to identify different acarid mites and was undertaken at Department of Entomology and Mushroom Research and Training Centre, Faculty of Horticulture, Sher-e-Kashmir University of Agricultural Sciences and Technology, Shalimar under temperate conditions of Kashmir. During the present study four acarid mites were found in the mushroom culture. The mites were collected, reared in the laboratory on fruiting bodies of mushroom till the emergence of adult. The specimens were preserved in Oudemans fluid and send for identification. The samples were identified as Tyrophagus putrescentiae, Acarus siro, Pygmephorus sellnicki and Rhizoglyphus robini. These mites usually develop on rotting plant remains permeated by fungal hyphae and cause significant damage to mushroom fruiting bodies. This was the first report of mite infestation on commercial mushrooms in Kashmir.
Demystifying the Need and Efficacy of Trial Examinations: Perspectives of Students and Teachers and Their Statistical Relationships with Examination Scores
Authors: Tenzin Karma
Published: September 2024

Trial or mock examinations for classes 10 and 12, conducted months before students appear for a high stake, externally administered and evaluated board examinations, came under scrutiny after an educational strategic documented recommended a review on its need and efficacy. Due to a lack of literature on the need and efficacy of trial examinations in Bhutanese educational context, a qualitative inquiry employing interviews with principals and focused group discussions with teachers was conducted to identify potential theories. Teacher accountability, assessment feedback, and prediction of students’ achievement in board examinations were used to justify the need and efficacy of trial examinations, while waste of instructional hours, teacher and student stress were the adverse consequences purported. The objectives of the research were to quantitatively test these assumptions and explore statistical relationships between trial examination and board examination scores. Primary data was collected from 261 teachers and 562 students. Trial and board examinations academic achievement results of 2432 class 10 and 557 class 12 students were collected. Descriptive statistics as well as inferential statistics were used to analyze the data. Results indicate that teachers perceive trial examinations as a necessary evil through which they learn more about students’ knowledge gaps to act upon, rather than being anxious about student achievement. Both students and teachers perceived that trial facilitates improved student achievement, when measured through examination marks. Trial examination marks demonstrate positive, weak to moderate correlation to board examination marks and the relationships are statistically significant. The perceptions that the planning and conduct of trial examinations are a waste of instructional time, lead to teacher and student stress were obtained to be myths. This research contributes to existing literature that low stakes testing programs facilitate improvement in student scores.

In developing countries, agriculture plays a vital role in reducing poverty and enhancing food security. In Sunamganj, Bangladesh, rural women significantly contribute to agriculture but face gender disparities and limited access to resources. Green cooperatives provide a promising model to empower these women through sustainable practices and economic support. This study explores the roles and impacts of green cooperatives on rural women entrepreneurs in Sunamganj, focusing on factors influencing their involvement, the benefits, and constraints they face, and changes in empowerment before and after joining cooperatives. This study was conducted across five upazilas in Sunamganj, the sampled 200 women entrepreneurs-100 cooperative members and 100 non-members using purposive and snowball sampling techniques. Data was gathered via interviews, surveys, and focus group discussions (FGDs) and analyzed with SPSS and Microsoft Excel. Multiple regression analysis was used to identify key influencing factors and the Problems Confrontation Index (PCI) was utilized to assess the severity of challenges faced by members. The findings reveal that green cooperatives enhance women’s socio-economic status through improved production, market access, financial stability, and decision-making roles. Education, credit access, input availability, training, and experience were key drivers of the cooperative engagement of rural women entrepreneurs. However, challenges like male dominance, limited training, transportation issues, labor shortages, and market information gaps persist. Despite these, women in green cooperatives benefit from fixed pricing for organic products, increased bargaining power, and timely access to inputs and training. The study highlights the need for improved education, continuous training, extension services, high-quality inputs, and better infrastructure to support women’s participation further. The insights provided aim to guide policymakers in developing supportive policies that enhance the impact of green cooperatives, address gender-specific challenges, and promote the use of digital tools for market access. Future research should explore longitudinal studies and regional comparisons for deeper insights into rural women’s empowerment.

A study was conducted to investigate how seed size affects germination and vigor of cowpea seeds. The differences due to vigour parameters of graded seeds were significant due to varieties cv. Bundel Lobia-1 showed better vigour than cv. UPC-607. Variety Bundel Lobia-1 recorded significantly higher seed weight (102.6 g) than variety UPC-607 (92.1 g). There was a significant difference between seed grades, large seeds having significantly more than 1000 seed weight (118.3 g) followed by ungraded seeds (107.2 g), medium seeds (97.1 g) and small seeds (66.8 g), respectively. Interaction Cv- Bundel Lobia-1 (93.0%) recorded a significantly superior germination percentage over cv. UPC-607 (86.48 %). However, the differences were non- significant due to seed sizes, large seeds (91.03%) recorded more germination percentage followed by medium seeds (90.34%), ungraded seeds (89.44%) and small seeds (88.16%) respectively.
