Trajetórias juvenis em um campo de contradições
Authors: Da Silva César Maurício , Antonio Scherer Giovane
Published: May 2023

O presente artigo busca analisar como vem se constituindo a exploração do trabalho juvenil no futebol e o seu impacto nas trajetórias, modos e condições de vida dos jovens. O estudo teve a intenção de identificar como vem se desenvolvendo o mercado da bola em tempos da fi nanceirização do capital, ao analisar como se confi gura o trabalho da juventude no que diz respeito à inserção no referido mercado. Frente a isso, tratou de verificar como o sistema de garantia de direitos atua na proteção social de adolescentes e jovens diante desse contexto. Tem como base uma investigação fundamentada no materialismo histórico-dialético, se constituindo como uma pesquisa qualitativa, de natureza exploratória e descritiva, por meio de um estudo de campo e revisão bibliográfica junto à Biblioteca Digital de Teses e Dissertações e Artigos do Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), incluindo materiais que tivessem relação com o tema das trajetórias juvenis no mercado de trabalho do futebol de alto rendimento. Em relação à pesquisa de campo, foram realizadas entrevistas semiestruturadas com jogadores de futebol, ex-jogadores e trabalhadores de comissões técnicas das categorias de base de clubes; com o objetivo de analisar questões que envolvem a exploração do trabalho, as trajetórias, modos e condições de vida a partir da inserção no mercado do futebol. Os resultados apontam para as diversas contradições que constituem a trajetória juvenil, marcadamente fetichizada, pois o mercado de trabalho no futebol para os jovens no caminho da profi ssionalização se manifesta por processos de precarização e violações de direitos. Os achados da pesquisa apontam para a necessidade de romper com os fetiches do mercado da bola, que estão entranhados no imaginário social, pois a realidade, para a maioria dos jogadores de futebol, é marcada pela descartabilidade, pelos baixos salários, pela flexibilização nas relações de trabalho e pelas estruturas de trabalho precarizadas, entre outras questões invisíveis para grande parte da sociedade. Essa aparência, muitas vezes, naturaliza, esconde e oculta processos de violação de direitos que os jovens no caminho da profi ssionalização do futebol podem vivenciar.
Significados e imágenes sobre el discurso político del liberalismo y conservadurismo en la Costa Rica liberal
Authors: Gómez Solano Juan Alberto
Published: May 2023

El artículo expone acerca del conjunto de significados y representaciones sociales que se conformaron alrededor de la discusión de los conceptos liberal-conservador para el caso costarricense, durante el ocaso del siglo XIX, y, los primeros años del siglo XX que estuvieron marcados por un ambiente político-electoral y sociocultural convulso y desigual dentro de la sociedad costarricense. Lo anterior, debido a tensiones que surgieron entre liberales y sectores populares conservadores que se encontraban acuerpados por la Iglesia católica. El texto desarrolla la temática siguiendo un enfoque que parte del análisis relacional de escalas espaciales derivado de la microhistoria italiana, es decir, de lo local a lo “nacional”, tomando como punto de partida el caso particular de la provincia de Cartago y cómo desde el entorno cartaginés, se conecta con la discusión de ambas nociones políticas a nivel país.
Caminar por tierras oscuras. Emilio Olsson y el colportaje como experiencia de viaje
Authors: Escobar Sepúlveda Darío , Núñez Paula Gabriela
Published: May 2023

Este artículo indaga la experiencia de viaje vinculada a la experiencia religiosa. Para ello toma el caso del misionero protestante, Emilio Olsson, el cual adoptó el colportaje como estrategia misional, que propició la instalación de nuevos proyectos protestantes en Sudamérica. Reflexionaremos sobre el viaje religioso, visto desde el descubrimiento y la evangelización, aún en el siglo XIX. Nuestra hipótesis sostiene que la forma introspectiva de vivir y practicar su fe impactó en la forma de reconocer el territorio latinoamericano al tiempo que impactó en la forma de exponer el rol estratégico del incremento de la práctica misional protestante en este mismo espacio.

Subjetividades urbanas en crisis. Un estudio de tres novelas de Carmen Naranjo Coto (1966-1968)
Authors: Cubillo Paniagua Ruth
Published: May 2023

La escritora costarricense Carmen Naranjo Coto (1928-2012) realiza, en sus primeras novelas, publicadas en la década de 1960, una profunda reflexión sobre la ciudad de San José y sus habitantes, quienes se enfrentan a procesos de convivencia en el contexto de una capital centroamericana que inicia su ingreso a la globalización. Para evidenciar esto, se analizan las novelas Los perros no ladraron (1966); Camino al mediodía (1968) y Memorias de un hombre palabra (1968), cuyos personajes son sujetos con preocupaciones propias del tránsito de la modernidad a la postmodernidad, pues lo que entra en crisis es la construcción misma de la subjetividad y el cuestionamiento de las verdades absolutas. Como ejes temáticos del análisis se proponen la indiferencia como generadora de angustia en el sujeto y la invisibilización del sujeto-ciudadano; asimismo, se entabla un diálogo entre las novelas de Naranjo y algunas de las propuestas conceptuales de autores como el filósofo y sociólogo Georg Simmel, el psicoanalista Sigmund Freud, el filósofo y sociólogo Herbert Marcuse y el crítico literario Rafael Valenzuela.
Conservación comunitaria en el Refugio de Vida Silvestre Gandoca- Manzanillo entre 1984-2007
Authors: Alvarado Luna German Daniel
Published: May 2023

El presente artículo tiene como objetivo analizar la implementación del paradigma de  conservación comunitaria en el Refugio de Vida Silvestre Gandoca-Manzanillo (RVS-GM ) entre 1984-2007 desde un enfoque de la Ecología Política, para establecer los vínculos entre ese proceso, la territorialización estatal,  y la neoliberalización de la naturaleza del espacio estudiado. Para cumplir este objetivo se hicieron entrevistas semi-estructuradas a actores locales e institucionales, y un análisis de la documentación producida por las instituciones, los medios de comunicación y organizaciones involucradas. Se concluye que las políticas de conservación comunitaria en el RVS-GM más que mermar el conflicto entre conservación y sociedad, son parte de los esfuerzos históricos del Estado  para reafirmar su soberanía e insertar los modos de producción capitalista en un espacio históricamente aislado con poblaciones con modos de vida relativamente autónomos. Dichas políticas son una expresión temporal específica de dichos esfuerzos, en tanto buscaron reducir los costos políticos y económicos del control y transformación de ese espacio mediante la cooptación del conflicto con  promesas de conservación y desarrollo, la descentralización de la toma de decisiones y la presentación anti-política de la intervención estatal, pero sin atender verdaderamente las desigualdades sociales  e inequidades de poder, por lo que terminaron reproduciendo la trayectoria histórica de exclusión y marginación.
Liberia y Rivas La construcción de un espacio regional de relaciones socioeconómicas, políticas culturales y geográficas en la frontera entre Nicaragua y Costa Rica. 1769-1860
Authors: Rivera Hernández Gina Nazareth
Published: May 2023

Las relaciones de Liberia y Rivas entre los siglos XVIII y XIX son un ejemplo de los contactos que se desarrollan en las fronteras de las provincias y los Estados centroamericanos.  En este artículo se intentan introducir una serie de temas que puedan servir como base para profundizar en la vida cotidiana de la región que representan los lazos desarrollados por esas comunidades. Aspectos como las características del espacio, el origen de los poblados, las haciendas de campo, las familias, la religión y las pugnas estatales demuestran como a pesar de las delimitaciones Liberia y Rivas mantuvieron sus vínculos abiertos conjugándose como región transfronteriza.
Reclusión y Trabajo: Relación, Lógica y Articulación en el Devenir del Presidio Chileno.
Authors: Romero Alejandro , Gil Villa Fernando
Published: May 2023

La presente investigación documental de carácter cualitativo, tiene por objetivo establecer los discursos legales y penales que dotan de sentido al trabajo de los reos en las cinco principales formas de reclusión evidenciadas en chile entre 1830 y 2000, para lo cual, se procedió a la revisión de leyes, normativa, escritos e investigaciones relacionadas con cada forma de reclusión. La tarea de análisis se realizó por medio de una malla temática y la tradición hermenéutica para ordenar la información (triangulación). Los resultados evidencian que el trabajo se concibe como un castigo adicional o complementario a la sanción, discurso que sólo cambia tras la instalación de la penitenciaría el año 1843, donde la actividad laboral del reo deja de beneficiar a otros centrándose en adelante en el propio recluso. Este cambio sin embrago, no alienta el trabajo en los presidiarios debido a la imagen de abuso y sometimiento que estos le asignan a su ejecución, y al nacimiento de una subcultura penitenciaria que estructurará una masculinidad y un deber-ser delictual temerario y contumaz (conclusión).

Authors: Múnera Montoya Juan Carlos , Arbeláez Caro Joan Sebastián , Tamayo Cardona Erika , Correa Ramírez Sara , Soto Ramírez María Camila
Published: May 2023

El objetivo general de la presente investigación fue explorar la dimensión psicológicarelacional de un grupo de mujeres conversas al islam en la ciudad de Medellín (Antioquia, Colombia). Como  metodología se eligió el paradigma de investigación cualitativo, específicamente, el diseño de la teoría fundamentada. Se aplicó un muestreo teórico del que se obtuvieron cuatro entrevistas a mujeres musulmanas conversas que se congregaron en alguna de las tres mezquitas de la ciudad de Medellín durante el año 2021. Los resultados muestran que el islam se convierte para ellas en una fuente de sentido de realidad y estilo de vida, que depende en gran medida de la percepción de sí, de las características y dinámica familiar y del ajuste social a la comunidad musulmana. Además, este permite asumir prácticas comunitarias, compromiso religioso y prácticas políticas.

APROBACIÓN PRESIDENCIAL Y VOTO POR EL PARTIDO EN EL GOBIERNO EN COSTA RICA (1982-2022). ANÁLISIS COMPARADO DE LAS EXCEPCIONES
Authors: Díaz Rodríguez Orestes Enrique
Published: May 2023

La aprobación del mandatario de turno ha constituido un predictor razonablemente confiable del éxito o la derrota del partido en el gobierno en Costa Rica. Para comprobarlo se conformó una muestra que abarcó los comicios presidenciales celebrados entre 1982 y 2022. Los resultados sugieren que el votante costarricense tiende a premiar o castigar al candidato presidencial oficialista en dependencia de la percepción que tienen sobre el desempeño del mandatario de turno. Los comicios de 1990 y 1994 constituyeron excepciones de esa dinámica. Ambas experiencias son analizadas a la luz de la experiencia comparada.
REPERTORIO DE POLÍTICAS PÚBLICAS EN EL CONGRESO PARA MITIGAR LAS CONSECUENCIAS DEL COVID-19 EN COSTA RICA
Authors: Abarca Rodríguez Allan , Barrios Rodríguez Sara
Published: May 2023

Este artículo es el resultado de un estudio de las propuestas de política pública presentados en el Congreso de Costa Rica para amortiguar o revertir los efectos socioeconómicos y de salud provocados por la pandemia del Covid-19. De todas las propuestas presentadas en los primeros seis meses de la declaratoria de emergencia ocasionada por el virus, en el año 2020, más de la mitad (194 en total) intentan mitigar uno o varios de los efectos de tal enfermedad infecciosa. Aún en la multiplicidad de protección a sectores específicos que se tratan de salvaguardar (33), hay una marcada tendencia en la regulación financiera-fiscal y de actuación en torno a la reactivación productiva. Pese a esto, una parte sustancial de las políticas planteadas para convertirseen leyes, no tienen un sustento financiero para ejecutarlas.
Análisis de potenciales manifestaciones superficiales de licuación por medio de índices de severidad a partir de información de CPT aplicado a la zona de Jacó, Costa Rica
Authors: Montalva Gonzalo , Cordero-Carballo Diego
Published: May 2023

Se evaluaron potenciales manifestaciones superficiales de licuación por medio de índices de severidad, a escala regional para la zona de Jacó, utilizando información generada por 15 sondeos CPTu, estimando la demanda sísmica de manera determinista para 24 escenarios, para aceleraciones esperadas a partir de ecuaciones de predicción del movimiento del suelo para América Central, considerando sismos corticales y por subducción, tanto intraplaca como interplaca. Los resultados permiten identificar tres zonas donde se esperarían diferentes niveles de daño, según la amenaza sísmica representada en los análisis por medio de la magnitud de un sismo y las aceleraciones que este podría producir, y priorizar aquellas a investigar con mayor detalle para el desarrollo de proyectos privados, de infraestructura púbica y la ubicación de edificaciones primordiales. La utilidad de los resultados se basa en orientar a autoridades municipales y de emergencia a anticipar la respuesta ante la ocurrencia de un escenario de análisis u otro con condiciones intermedias, en conocer anticipadamente la distribución de los sitios donde el daño podría ser mayor para orientar los esfuerzos en cuanto a respuesta inmediata y recuperación. Se espera que los resultados de este proyecto, si bien preliminares, sirvan como insumo para la gestión del riesgo asociado a licuación por medio de medidas ingenieriles y de otra naturaleza, para efectos de ordenamiento territorial y para el desarrollo de políticas públicas para el distrito de Jacó, como podría ser un plan regulador.
Decolonising history teaching in the United Kingdom: Movements, methods, and curricula
Authors: Szabó-Zsoldos Gábor
Published: May 2023

Toppling the statue of the slave merchant Edward Colston in Bristol, removing the monuments of King Leopold II from public places in Belgium, Black Lives Matter protests, and mass demonstrations targeting remembrance of certain chapters of the history of the Global North – these are some of the significant events that drew attention to the ongoing disputes around the legacy of colonialism during the summer of 2020. These developments form an integral part of the long-drawn-out process of decolonisation: decolonising the culture of the former mother countries. From museology through the natural sciences and linguistics to visual arts, vast areas of the academic, scientific, and cultural scene of the Global North are crucially affected by decolonizing tendencies, with the teaching of history arguably among the most disputed ones. This paper reviews the key decolonising aspirations of history teaching in the United Kingdom by studying the goals, messages, methods, and endeavours of three movements: Why Is My Curriculum White?, The Black Curriculum, and Rhodes Must Fall Oxford, address different levels of education and urge the transformation of numerous aspects of history teaching (teacher training, curricula, teaching methodology, etc). Source materials examined include the work, teaching aids, and written, audio, or video content published on various social media platforms by these three organisations, as well as parliamentary papers and reports of public and non-governmental bodies.
Motility related gene expression of Campylobacter jejuni NCTC 11168 derived from high viscous media
Authors: Su Yulan , Alter Thomas , Gölz Greta
Published: May 2023

Flagellation is one of the major virulence factors of Campylobacter jejuni (C. jejuni), enabling bacterial cells to swarm in rather high viscous fluids. The aim of this study was to determine the impact of the surrounding viscosity on the expression of motility related genes of C. jejuni. Therefore, bacterial RNA was extracted from liquid cultures as well as from bacterial cells recovered from the edge and the center of a swarming halo from high viscous media. The expression pattern of selected flagellar and chemotaxis related genes was investigated by RT-PCR. Higher mRNA levels of class 1 and lower levels of class 2 and 3 flagellar assembly genes were detected in cells derived from the edge of a swarming halo than in cells from the center. This indicates different growth states at both locations within the swarming halo. Furthermore, higher mRNA levels for energy taxis and motor complex monomer genes were detected in high viscous media compared to liquid culture, indicating higher demand of energy if C. jejuni cells were cultivated in high viscous media. The impact of the surrounding viscosity should be considered in future studies regarding motility related questions.

Authors:   The Hashemite University, Jordan, Ghbari Thaer A.
Published: May 2023

The current study aimed to explore the effect of regulatory Focus – Promotion vs. Prevention – in problem-solving among undergraduate students at The Hashemite University. The hypotheses were that promotion focus students outperform prevention focus students in ill-structured problems but underperform them in well-structured problems, and prevention focus students outperform promotion focus students in well-structured problems but underperform them in ill-structured problems. The participants (n=170) were allocated into four groups according to their mindsets and the problems assigned to them (promotion with ill-structured problems, promotion with well-structured problems, prevention with ill-structured problems, prevention with well-structured problems). After the groups solved all the assigned problems, their work was scored according to Measuring Problem Solving Instrument MPSI. The findings confirmed the hypothesis that the regulatory focus affects how problems are solved.

Published: May 2023

Amniotic fluid abnormalities are caused by perinatal death and morbidity. Foetal growth and development are examples of parameters that must be accessible. Ultrasound technology is used to make an image of the uterus. Main aim of this work is to reduce the mortality and morbidity. Because, every year, 30 million new-borns have growth limitation, and there is a link between oligohydramnios (lack of amniotic fluid) and perinatal death. AFI can be measured with the assistance of ultrasound images. It is divided into four equal quadrants, with the Amniotic Fluid Index being the average of these quadrants (AFI). The performance of an Adaptive Neuro-Fuzzy Inference classifier is used for classification techniques. For the implementation of this research uses convolution neural network. During the second and third trimesters of pregnancy, this method is used to detect malformations using deep learning techniques. This strategy aims to reduce diagnostic time and risk factors in earlier stages of pregnancy.

Published: May 2023

Developments in computer communications and networks enabled the deployment of exciting new areas. Meanwhile, Efficient network and communication technologies also promote the development of routing protocols. AODV(Ad hoc On-Demand Distance Vector Routing, AODV) routing protocol has invulnerability to different mobile attributes of agent nodes and network damage scenarios. However, this invulnerability performance can not meet the needs of mobile multi-agent cooperative communication. Therefore, this paper proposes an improved responsive multipath routing protocol MD_AODV(Multipath Destroy-resistance AODV, MD_AODV). This routing protocol is based on AODV routing protocol. It is mainly improved in three aspects: multichannel concurrency mechanism, node load balancing mechanism and shortest path maintenance mechanism. Firstly, in this research, an improved multipath routing protocol is modeled and implemented, which is based on OPNET Network simulation platform. Then, network models with different degrees of impairment are built. Combines the mobile attributes of mobile multi-agent task coordination to carry out invulnerability simulation experiments . These experiments study the invulnerability of the improved multipath routing protocol. Finally, this paper evaluates and compares the routing invulnerability of MD_AODV, AODV and AOMDV(Ad-hoc On-Demand Multipath Distance Vector, AOMDV). The evaluation results show that MD_AODV routing has better invulnerability when the network is severely damaged
Categorical Feature Encoding Techniques for Improved Classifier Performance when Dealing with Imbalanced Data of Fraudulent Transactions
Authors: Breskuvienė Dalia , Dzemyda Gintautas
Published: May 2023

Fraudulent transaction data tend to have several categorical features with high cardinality. It makes data preprocessing complicated if categories in such features do not have an order or meaningful mapping to numerical values. Even though many encoding techniques exist, their impact on highly imbalanced massive data sets is not thoroughly evaluated.

Two transaction datasets with an imbalance lower than 1\% of frauds have been used in our study. Six encoding methods were employed, which belong to either target-agnostic or target-based groups. The experimental procedure has involved the use of several machine-learning techniques, such as ensemble learning, along with both linear and non-linear learning approaches.

Our study emphasizes the significance of carefully selecting an appropriate encoding approach for imbalanced datasets and machine learning algorithms. Using target-based encoding techniques can enhance model performance significantly. Among the various encoding methods assessed, the James-Stein and Weight of Evidence (WOE) encoders were the most effective, whereas the CatBoost encoder may not be optimal for imbalanced datasets. Moreover, it is crucial to bear in mind the curse of dimensionality when employing encoding techniques like hashing and One-Hot encoding.
Status, Challenges and Trends in Videoconferencing Platforms
Authors: Suduc Ana-Maria , Bizoi Mihai , Filip Florin Gheorghe
Published: May 2023

Although videoconferencing platforms were a growing market even before the Covid-19 pandemic, they became very popular and widely used within weeks of the beginning of the pandemic. The compulsion of social distancing, lockdown, the need to work from home have led to an exponential demand for videoconferencing applications and an adaptation of the way we carry out our current activities such as work, decision-making, communicating with family and colleagues, or education. With the diversification of the categories of users of videoconferencing systems and the contexts in which they were used, many other needs have emerged and the demand to adapt these platforms, both in terms of ease of use and functionality, as well as security. Videoconferencing systems are no longer meant only for decision-makers or trainers, but also for general public. This paper reviews various data regarding the use of videoconferencing systems in recent years, a number of problems encountered by users, and expected trends in the future.

Abstract Objective: to analyze the temporal trend of Food and Nutrition Surveillance System (Sistema de Vigilância Alimentar e Nutricional - SISVAN) coverage and the nutritional status of older adults, and its correlation with indicators of social inequality in Brazil between 2008-2019. Methods: this was an ecological study using records from SISVAN, related to the population aged 60 years and older; the temporal trend of coverage and the correlation between indicators of social inequality and increment rate of nutritional status were analyzed; slope index of inequality and concentration index were used to measure absolute and relative inequalities. Results: 11,587,933 records were identified; national coverage increased from 0.1% (2008) to 2.9% (2019), with a statistically significant upward trend; a moderate inverse correlation with an annual increment rate of overweight between human development index and gross domestic product per capita, was found. Conclusion: there was an increasing trend in SISVAN coverage; the increase in overweight was associated with social inequality.

Construyendo capacidades para la innovación orientada: la respuesta argentina con perspectiva de género a la covid-19
Authors: Mucarsel Leila , Barile Ana Clara , Bhat Meera
Published: May 2023

La pandemia puso a prueba la resiliencia de los sistemas públicos, pues los Gobiernos enfrentaron el desafío de adaptar rápidamente sus políticas y prácticas. En ese contexto, Argentina fue reconocida como uno de los pocos países que logró transversalizar la perspectiva de género para alcanzar a las poblaciones más vulnerables, mostrando capacidades de adaptación y orientación estratégica. En este artículo se busca captar, sistematizar y repensar –en el contexto de las políticas de innovación orientadas por misiones– las estrategias desplegadas por el Gobierno argentino. El objetivo es comprender qué capacidades resultan claves para el abordaje de problemáticas sociales complejas en el Sur Global y cómo estas pueden nutrirse. A través de un marco teórico que articula la literatura sobre “capacidades dinámicas del sector público” y “capacidades estatales” en América Latina, y la aplicación de una metodología cualitativa (estudio de caso), encontramos que las capacidades estatales se fortalecieron reconfigurando recursos preexistentes a partir de un proyecto de gobierno, liderazgos colectivos, y una serie de innovaciones institucionales y políticas en el contexto del auge de los feminismos regionales. Esta experiencia, que le ha valido a Argentina el reconocimiento mundial, ofrece importantes lecciones para abordar los retos sociales mediante políticas de innovación, la institucionalización de las demandas de los movimientos populares y las colaboraciones para lograr sistemas resilientes.

BACKGROUND: Bone tumours involving hands are usually benign but can be locally aggressive. Several treatments have been described. Usual modalities of treatment include curettage and bone grafting. In more advanced stages when short bones of the hand are involved with more than 70% cortical destruction, or when such treatment option is not possible (as with non-contained tumours with cortical breaches, pathological fracture), only the resection or amputation of the affected segment can offer an effective cure. We studied the role of the free fibula graft (non-vascularised) in such types of benign non-reconstructable (by conventional methods) hand tumours. The aims and objectives were to study the functional outcome of free fibula grafting in benign non-reconstructable bone tumours involving the hand and to analyse the complications, if any, and assess the causes and solutions for them METHODS: We prospectively studied 15 patients with different types of benign, non-reconstructable bone tumours involving the hand operated by free fibula grafting. The study period ranged from January 2014 to December 2021. Follow-up ranged from 2 to 8 years (average of 4.26 years RESULTS: Results were analysed by the QuidkDASH-9 score system. There was no recurrence. One case of superficial infection was treated with antibiotics and dressing. All patients were happy with the treatment and resumed their normal duties and functional movements CONCLUSION: Use of the free fibula graft can be a good option for benign non-reconstructable bone tumours involving the hand to avoid amputation. The free fibula graft gives better results due to total excision of the lesion and strut graft support for good functional outcomes Level of evidence: Level 3

BACKGROUND: Paediatric bone and joint infections remain common in low- and middle-income countries (LMICs) and may have devastating long-term sequelae. There is a paucity of data from LMICs where the true incidence might be underreported, and delayed presentation is common. Our study aimed to determine the complication rate and incidence of disseminated infection in paediatric bone and joint infections in an LMIC setting. Secondly, we aimed to elucidate factors associated with complications and disseminated disease METHODS: We retrospectively reviewed our paediatric orthopaedic database for children that presented with bone and joint infections between September 2015 and March 2019. Data were extracted from medical records, laboratory results and radiological investigations to identify factors that were associated with the development of complications and disseminated infection at a median follow-up of four months RESULTS: We analysed 49 children. The median age at presentation was 6 years (range 1 month to 12 years). Locally advanced disease, with combined acute haematogenous osteomyelitis (AHOM) and septic arthritis (SA), was present in 13 children (27%). The remaining 36 children were evenly divided (18/49 each, 37%) between isolated AHOM and SA, respectively. Disseminated disease was present in 16 children (33%) and was associated with locally advanced disease, an increase in the number of surgeries and an increased length of stay. Twenty-six complications were documented in 22 (45%) children. Chronic osteomyelitis developed in 15/49 (31%) cases, growth arrest in 5/49 (10%), and pathological fracture, DVT and septic shock in 2/49 (4%) each. Complicated disease was associated with locally advanced disease, a higher number of surgeries, disseminated disease and an increased length of stay. Staphylococcus aureus was the infecting pathogen in 65% of cases (31 MSSA, 1 MRSA), while 25% (12/49) were culture-negative infections. While the median time from admission to surgery was one day, the median time from onset of symptoms to surgery was seven days CONCLUSION: We found a high complication rate despite a short follow-up period. More than a quarter of patients had locally advanced disease, and this was associated with the development of complications and disseminated disease. Further studies are needed to be able to predict which children will have poor outcomes Level of evidence: Level 4
Colorimetric LAMP/RT-LAMP Protocol v1
Authors: Navarro Martínez Felipe
Published: May 2023

This protocol describes how to perform colorimetric LAMP / RT-LAMP reactions with homemade buffers, together with home-brewed BstLF and MMLV enzymes. It is based on previous protocols of our lab (see LAMP/RT-LAMP Reaction protocol), but since two of the most common indicators used in colorimetric LAMP (phenol red and neutral red) require weakly buffered reactions, the buffer composition needed to be changed. This was done according to indications by Poole et al (2017). The colorimetric methods rely on the inherent proton production by DNA polymerases during the amplification process, which leads to a drop in the reaction pH that can be followed using these pH indicators. The results can be seen directly with the "naked eye", without the need for equipment or hands-on processing (Tanner et al., 2015).

Sowing dates and harvest stages are very important to obtained better forage yield and quality. The goal of the study was to ascertain how the quinoa growing conditions in Marmara will be affected by the sowing dates and harvest stages. In 2018 and 2019, the experiment was conducted in an experimental field in the Agricultural Application and Research Area of Bursa Uludag University's Agriculture Faculty. The field experiment was set up using three replicates of a split-plot randomized complete blocks design. Titicaca variety of quinoa was used as a plant material in the study. Four different sowing dates (15 April, 1 May, 15 May and 1 June) were considered in the main plot and three different harvest stages (beginning of flowering, full flowering and seed setting) in the sub-plot. In this study, plant height, dry matter yield, crude protein, crude protein yield, neutral detergent fiber, acid detergent fiber, the relative feed value, and macro and micro elements were examined. The two-year findings show that sowing on May 1 produced the maximum dry matter yield (2798 kg ha-1) and crude protein yield (584 kg ha-1). In terms of harvest stages, seed setting stage came to the fore in terms of high forage (4001 kg ha-1) and crude protein yield (746 kg ha-1).

Microbial fertilizer helps the plants grow healthy and stay strong due to including fertilizer and beneficial microorganisms. The purpose of the study was to determine the effects of microbial fertilizers applied in different growth stages on oil content, fatty acid composition and oil quality of peanut (Arachis hypogaea L.). The study was conducted in Osmaniye/Turkey in 2019 and 2020 according to RCBD arranged in split-plots design with 3 replications. The highest oil contents were observed in 150 cc da-1 (53.07%) and beginning bloom + full bloom (53.95%) treatments in studied years. For total unsaturated fatty acid compositions, the highest values were obtained in full bloom (79.49%) and 100 cc da-1 (79.99%) treatments. The highest O/L ratio were observed in full bloom and 100 cc da-1 treatments as 1.72 and 1.68, respectively according to mean of 2-year values. Similar results were seen in IV, and these treatments came forefront with the values 93.83 and 94.52, respectively. As a results of the study, it was concluded that (i) microbial fertilizers had the positive effects on oil content and quality parameters of peanut, (ii) the treatment 100 cc da-1 applied in full bloom may be the optimum selection.

Background: Teachers’ knowledge of mathematical reasoning and how to foster it in pupils influence the way they plan and conduct their lessons. In geometry, it implies developing visualisation and spatial structuring. Objectives: This article addresses the knowledge of the preservice and in-service primary teachers about reasoning processes, namely the way they relate several reasoning processes when solving a didactical task involving geometry. Design: The study reported here followed a qualitative-interpretative approach, adopting a design-based research modality. Setting and Participants: The teacher education experiments were developed with 31 preservice primary teachers and 19 in-service teachers of grades 1 to 6. The participants were not selected since they were the unique classes of pre- and in-service primary teachers in the institution. Data collection and analysis: Data were collected by audio and video records of lessons, participant observation and the collection of written records of the preservice teachers. We used content analysis of the data using the framework we elaborated on before concerned with knowledge of reasoning processes. Results: The preservice teachers identified the process of generalising, relating it with comparing and exemplifying processes. Regarding the process of justifying, participants used the association to understand why a relationship works as a selection criterion for that process. On the contrary, the distinction between justifying and generalising appeared to be more difficult for in-service teachers. Conclusions: Collaborative work on didactical tasks that are supported by relevant mathematical tasks and real classroom episodes are promising scenarios to develop teachers’ knowledge about mathematical reasoning.
