Los procesos de transferencia educativa entre países y su impacto en el surgimiento de una comunidad de especialistas en educación matemática: el caso de la construcción del currículo para la enseñanza básica de la ciudad de Buenos Aires
Authors: Deriard Alejandra , Federico Lucia
Published: July 2022

En este artículo, nos adentramos en la escritura de la Historia del Currículo de Matemática para la Enseñanza Básica de la ciudad de Buenos Aires (1983-2004). Se entrecruzan para el análisis fuentes primarias y secundarias, además de la Memoria de los actores involucrados en esta Historia Presente, integrándolos en un esquema hermenéutico que da cuenta de la Historia del Currículo de Matemática en estas latitudes. Como conclusión se mostrará que el diseño curricular implementado en 2004 en la Ciudad de Buenos Aires, fue concebido por un grupo de investigación que se nutrió principalmente por los modos investigativos de la Teoría de Situaciones Didácticas, de Guy Brousseau, generando una comunidad de didactas a imagen y semejanza de dicha teoría, es decir bajo un paradigma. Para lograr este escrito, nuestro marco de referencia se inscribe en el esquema interpretativo de Cesar Lorenzano (1995, 1999), quien retoma los escritos del historiador de la Ciencia Tomas Kuhn (1971), y los flexibiliza, incluso para comprender los cambios en los movimientos referidos al arte. Su encuadre es clave a nuestros fines: los marcos interpretativos de un Historiador de la Ciencia no se originan ni en el sentido común, ni en la propia Ciencia, sino en la Filosofía de la Ciencia.
Subjetivarse en una escuela marginalizada: Una etnografía con niños leída desde el psicoanálisis de Winnicott
Authors: Armijo Cabrera Muriel
Published: July 2022

Este artículo presenta la evolución de un objeto de estudio a través del análisis de los datos etnográficos producidos en una escuela marginalizada de Santiago de Chile. La investigación tenía como objetivo conocer los procesos de inclusión/exclusión social que experimentan los niños en ese entorno, utilizando un marco teórico post-estructuralista de la subjetivación (Foucault, Deleuze, Butler). No obstante, durante el proceso de campo, se producen datos sorpresivos que requieren un marco conceptual más concreto para poder ser interpretados y analizados. La subjetivación se lee entonces desde el psicoanálisis de Winnicott, quien incorpora la dimensión inconsciente de la experiencia humana y permite entender cómo los niños se movilizan hacia los saberes escolares. La metodología del estudio fue una post-etnografía escolar visual, que se desplegó durante 7 meses, con investigación de campo, producciones visuales infantiles y entrevistas con grupos de niños. Se presentan cinco momentos claves en los procesos de subjetivación infantil, los cuales permiten entender los datos generados en el trabajo de campo, y delinean maneras de acercarse a los saberes escolares. Estos resultados parecen fundamentales para repensar la formación docente.

Authors: Calderón Soto Maribel , Sebastián Balmaceda Christian
Published: July 2022

El foco de esta investigación es la reconstrucción de los ejes centrales desde los cuales se estaría sosteniendo la elaboración de una identidad docente en académicos chilenos, tomando como ejes la trayectoria profesional y la labor de enseñanza. El propósito es evidenciar la heterogeneidad de las condiciones en la que se trabaja en la universidad del siglo XXI en Chile y discutir respecto a cómo se articulan con la construcción de sentido identitario profesional. Participaron 12 académicos de universidades nacionales, con adscripción diversa en contrato, tareas y disciplinas. Mediante un enfoque cualitativo, la construcción de relatos de práctica y su posterior análisis con técnicas narrativas y estructurales se construyeron categorías comunes y aspectos diferenciadores. Entre los resultados se describe la relación institución-trabajador, valoración del trabajo docente y se propone una síntesis a través de motivadores centrales del ejercicio docente en la educación superior. Se discute cómo los relatos visibilizan las problemáticas actuales de la construcción de sentido del trabajo universitario en un contexto heterogéneo y cambiante.
Conciliación trabajo-familia con y sin niños y niñas, durante el confinamiento por COVID-19 en México
Authors: Meza-de-Luna María Elena , Conde Morelos Zaragoza Tania María , Meza-de-Luna Leticia
Published: July 2022

La implementación del confinamiento como política sanitaria por COVID-19, transformó el hogar, más allá de la vida familiar, en el lugar de trabajo y de la escuela. En ese contexto, analizamos la conciliación trabajo-familia (CTF) en función del género y de tener o no niños/as, en un estudio con enfoque mixto. Aplicamos 578 cuestionarios on-line y 50 entrevistas a trabajadores/as mexicanos/as. Encontramos que en medio del acelerado cambio hacia el trabajo virtual, se han desdibujado los roles profesional y privado. El home-office irrumpió en la vida privada resultando en enmarañamiento de funciones, jornadas de trabajo extenuantes, políticas institucionales desfavorables para la CTF y hostilidad de compañeros/as de trabajo, todo lo cual disparó estrés y frustración en los/as trabajadores/as, principalmente en padres/madres. Para las mujeres con niños/as, aumentó tres veces el riesgo de desempleo. Así, este confinamiento accionó, sin planearlo, un experimento social que nos permite ver algunos de los efectos del conflicto trabajo-familia, y la dificultad que implica la CTF frente a la implementación abrupta y masiva de políticas acordes al modelo neoliberal.
Masculinidades hegemônicas sob o olhar infantil
Authors: Esper Marcos , Fernández Unsain Ramiro , Figari Cecilia
Published: July 2022

As formas como se distribuem as relações de gênero na sociedade começam na infância e as crianças não recebem de forma passiva os estereótipos de sexo e gênero. Elas operam sobre estas diferenciações que são feitas desde a sua socialização primária. As instituições escolares, em diálogo com as próprias unidades domésticas, e através de suas regras, são importantes ferramentas para a construção das conformações identitárias de sexo genéricas das crianças. Estas instituições, geralmente, canalizam representações hegemônicas sobre diferentes dimensões socioculturais às quais as ideias predominantes sobre gênero e sexo também alcançam. Assim, neste trabalho, examinamos como alunos, autoidentificados e identificados pelos outros como “meninos” e respondem à pergunta: “O que é ser menino?”, através dos próprios desenhos. Concluímos que resulta relevante que as crianças sejam incentivadas a refletir sobre o modelo tradicional de masculinidade. Este primeiro relevamento, parte de uma pesquisa em andamento, indica que é positivo que as crianças reflexionem além dos discursos naturalizados e reproduzidos acriticamente treinando a própria refletividade sobre a sexualidade e o gênero, mas também se empoderando como sujeitos questionadores e reflexivos.

Converting Velocity Pressure into Cubic Feet per Minute (CFM)
Authors: Robinette Darrian
Published: July 2022

Almost every building in the United States has a HVAC (Heating, ventilation, and air conditioning) system that relies on balancing Velocity Pressure and calculated CFM to properly control the atmosphere in a building. This is ensured and tested by Field Engineers whose job it is to maintain the efficiency and proper output of these HVAC systems. These systems are used to improve indoor air quality, control moisture and condensation, and contaminants while satisfying comfort needs of occupants. Just with any mechanical system, HVAC systems function efficiently with multiple formulas derived from calculus and physics. Every building is equipped with a system that needs to meet a certain threshold of air movement, measured in Cubic Feet per Minute (CFM), that creates a stable and comfortable indoor atmosphere by testing and balancing these systems with Velocity Pressure. Velocity Pressure is the base reading it takes to understand and adjust air movement within a HVAC system to guarantee the overall best quality of an indoor air environment. Once a measurement of Velocity Pressure, measured in inches of water column (in-WC) using a tool called a Flow Hood or Straight Pitot Tube, is taken then you can start to calculate flow readings and test if a fan is producing the correct amount of CFM that the system was built to produce and support. This testing is done by using a series of calculus and algebraic equations that takes area and velocity into consideration. When solving these formulas, it can then be determined if a HVAC system and its fans are producing the ideal amount of airflow and air quality to accurately produce the precise environment for any building.

The Birth of the Local Feminist Sphere
in the Global Era : Yeoseongjang and
“Trans-Cinema”
Authors: Soyoung Kim
Published: July 2022

In this chapter, I will adopt and adapt two terms from other contexts
as a means of reframing an understanding of Korean cinema history
and intervening in that history. I will use yeoseongjang and “transcinema”
to identify specific counter-strategies deployed within feminist
cultural-political practices. Furthermore, I propose this use of these
terms as another counter-strategic response to the operations of
legitimation, delegitimation and exclusion that permeate dominant
discourses, institutional practices and habits of signification underlying
the formation of canons and archives, cinematic and otherwise. In
particular, yeoseongjang and “trans-cinema” will articulate modes of
cultural production as alternatives to the Korean blockbuster, often by
reinhabiting the various digital communication devices most closely
identified with the global capitalism essential to the blockbuster’s
hegemony.

Published: July 2022

Using a method of multidimensional analysis, this study compares several renewable resources and technologies. Using the check-list matrix method, the environmental impacts of various renewable technologies are evaluated and compared based on their significance, impact, and duration. Based on their impact on soil, air, and water resources, solar thermal technologies and direct combustion of bio-mass resource have the highest impact scores, 31 and 27, respectively. With an impact score of 12, renewable energy from run-of-river is the most promising and sustainable option, followed by wind and solar PV with scores of 23 and 24 respectively. Based on the qualitative analysis conducted in the study, it can be concluded that all renewable technology options have a low to high varying significance impact on the environment and cannot be considered a comprehensive solution to Pakistan's environmental problem.

Authors: Awais Muhammad , Irfan Walid , Zareen Naila , Ahmed Iftikhar
Published: July 2022

Transient stability analysis has become an important subject, as the world’s demand for electricity is increasing with an enormous speed, and power systems are facing different challenges, new power plants are being installed to fulfill the demand and supply mismatch, in addition to that degradation of equipment, sudden load changes and switching operations are also some of the problems in large networks. For large power systems it is a highly non-linear problem and also used to analyze whether the system remain in synchronism or not following a disturbance. To analyze the effect of these disturbances and consequences of the outages transient stability analysis is usually performed. In this paper this analysis is performed for an HPR-1000 nuclear power plant connected to the 500kV network of NTDC Grid. Different external 3-phase fault scenarios are considered on the 500kV network and simulated using ETAP (Electric Transient Analyzer Program) software. To analyze the system behavior during and after the fault has occurred, certain parameters are monitored. It was observed that the HPR-1000 power plant-maintained synchronism and remained stable in all the fault scenarios.

The follow-up and data analysis explore and reveal changes and emerging trends that arose announcement of the agile technique which is mentioned in this paper, and also has gained increasing prominence in agile in product development over the last couple of years.
Evaluating the performance of a Picarro G2207-i analyser for high-precision atmospheric O2 measurements
Authors: Fleming Leigh S. , Manning Andrew C. , Pickers Penelope A. , Forster Grant L. , Etchells Alex J.
Published: July 2022

Abstract. Fluxes of oxygen (O2) and carbon dioxide (CO2) in and out of the atmosphere are strongly coupled for terrestrial biospheric exchange processes and fossil fuel combustion but are uncoupled for oceanic air-sea gas exchange. High-precision measurements of both species can therefore provide constraints on the carbon cycle and can be used to quantify fossil fuel CO2 (ffCO2) emission estimates. In the case of O2, however, due to its large atmospheric mole fraction of O2 (~20.9 %) it is very challenging to measure small variations to the degree of precision and accuracy required for these applications. We have tested an atmospheric O2 analyser based on the principle of cavity ring-down spectroscopy (Picarro Inc., model G2207-i), both in the laboratory and at the Weybourne Atmospheric Observatory (WAO) field station in the UK, in comparisons to well-established, pre-existing atmospheric O2 and CO2 measurement systems. In laboratory tests analysing air in high-pressure cylinders, from the Allan deviation we calculated a precision of ± 1 ppm (1σ standard deviation of 300 seconds mean), and a 24-hour peak-to-peak range of hourly averaged values of 1.2 ppm. These results are close to atmospheric O2 compatibility goals as set by the UN World Meteorological Organization. From measurements of ambient air conducted at WAO we found that the built-in water correction of the G2207-i does not sufficiently correct for the influence of water vapour on the O2 mole fraction. When sample air was pre-dried and employing a 5-hourly baseline correction with a reference gas cylinder, the G2207-i’s results showed an average difference from the established O2 analyser of 13.6 ± 7.5 per meg (over two weeks of continuous measurements). Over the same period, based on measurements of a so-called “target tank” (sometimes known as a “surveillance tank”), analysed for 12 minutes every 7 hours, we calculated a repeatability of ± 5.7 ± 5.6 per meg and a compatibility of ± 10.0 ± 6.7 per meg for the G2207-i. To further examine the G2207-i’s performance in real-world applications we used ambient air measurements of O2 together with concurrent CO2 measurements to calculate ffCO2. Due to the imprecision of the G2207-i, the ffCO2 calculated showed large differences from that calculated from the established system, and had a large uncertainty of ± 13.0 ppm, which was roughly double that from the established system (± 5.8 ppm).
The hourly wind-bias adjusted precipitation data set from the Environment and Climate Change Canada automated surface observation network (2001–2019)
Authors: Smith Craig D. , Mekis Eva , Hartwell Megan , Ross Amber
Published: July 2022

Abstract. The measurement of precipitation in the Environment and Climate Change Canada (ECCC) surface network is a crucial component for climate and weather monitoring, flood and water resource forecasting, numerical weather prediction and many other applications that impact the health and safety of Canadians. Through the late 1990s and early 2000s, ECCC surface network modernization resulted in a shift from manual to automated precipitation measurements. Although many advantages to automation are realized, such as enhanced capabilities for monitoring in remote locations and higher frequency of observations at lower cost, the increased reliance on automated precipitation gauges has also resulted in additional challenges, especially with data quality and homogenization. The automated weighing precipitation gauges used in the ECCC operational network have an increased propensity for wind-induced undercatch of solid precipitation. One outcome of the WMO Solid Precipitation Inter-Comparison Experiment (SPICE) was the development of transfer functions for the adjustment of high frequency solid precipitation measurements made with gauge/wind shield configurations used in the ECCC surface network. Using the SPICE Universal Transfer Function (UTF), hourly precipitation measurements from 397 ECCC automated climate stations were retroactively adjusted for wind undercatch. The data format, quality control and adjustment procedures are described here. The hourly adjusted data set (2001–2019, version v2019UTF) is available via the ECCC data catalogue: https://doi.org/10.18164/6b90d130-4e73-422a-9374-07a2437d7e52 (ECCC, 2021). A basic spatial impact assessment shows that the highest relative total precipitation adjustments occur in the Arctic where solid precipitation has an overall higher annual occurrence ratio. The highest adjustments for solid precipitation are shared by the Arctic, southern Prairies and the coastal Maritimes, where stations tend to be more exposed and snowfall events occur at higher wind speeds.
Root-mean-square error (RMSE) or mean absolute error (MAE): when to use them or not
Authors: Hodson Timothy O.
Published: July 2022

Abstract. The root-mean-squared error (RMSE) and mean absolute error (MAE) are widely used metrics for evaluating models. Yet, there remains enduring confusion over their use, such that a standard practice is to present both, leaving it to the reader to decide which is more relevant. In a recent reprise to the 200-year debate over their use, Willmott and Matsuura (2005) and Chai and Draxler (2014) give arguments for favoring one metric or the other. However, this comparison can present a false dichotomy. Neither metric is inherently better: RMSE is optimal for normal (Gaussian) errors, and MAE is optimal for Laplacian errors. When errors deviate from these distributions, other metrics are superior.
Evaporation, infiltration and storage of soil water in different vegetation zones in the Qilian Mountains: a stable isotope perspective
Authors: Zhu Guofeng , Yong Leilei , Zhao Xi , Liu Yuwei , Zhang Zhuanxia , Xu Yuanxiao , Sun Zhigang , Sang Liyuan , Wang Lei
Published: July 2022

Abstract. The processes of water storage have not been fully understood in
different vegetation zones of mountainous areas, which is the main obstacle
to further understanding hydrological processes and improving water resource assessments. To further understand the process of soil water movement in different vegetation zones (alpine meadow (AM), coniferous forest (CF), mountain grassland (MG) and deciduous forest (DF)) of mountainous areas, this study monitored the temporal and spatial dynamics of hydrogen- and oxygen-stable isotopes in the precipitation and soil water of the Xiying River basin. The results show that the order of soil water evaporation intensities in the four vegetation zones was MG (SWLslop: 3.4) >  DF (SWLslop: 4.1) >  CF (SWLslop: 4.7) >  AM (SWLslop: 6.4). The soil water in the AM and CF evaporated from only the topsoil, and the rainfall input was fully mixed with each layer of soil. The evaporation signals of the MG and DF could penetrate deep into the middle and lower layers of the soil as precipitation quickly flowed into the deep soil through the soil matrix. Each vegetation zone's water storage capacity of the 0–40 cm soil layer followed the order of AM (46.9 mm) >  DF (33.0 mm) >  CF (32.1 mm) >  MG (20.3 mm). In addition, the 0–10 cm soil layer has the smallest soil water storage capacity (AM: 43.0 mm; CF: 28.0 mm; MG: 17.5 mm; DF: 29.1 mm). This work will provide a new reference for
understanding soil hydrology in arid headwater areas.
On the similarity of hillslope hydrologic function: a clustering approach based on groundwater changes
Authors: Maina Fadji Z. , Wainwright Haruko M. , Dennedy-Frank Peter James , Siirila-Woodburn Erica R.
Published: July 2022

Abstract. Hillslope similarity is an active topic in hydrology because of its importance in improving our understanding of hydrologic processes and enabling comparisons and paired studies. In this study, we propose a holistic bottom-up hillslope clustering based on a region's integrative hydrodynamic response quantified by the seasonal changes in groundwater levels ΔP. The main advantage of the ΔP clustering is its ability to capture recharge and discharge processes. We test the performance of the ΔP clustering by comparing it to seven other common hillslope clustering approaches. These include clustering approaches based on the aridity index, topographic wetness index, elevation, land cover, and machine-learning that jointly integrate multiple data. We assess the ability of these clustering approaches to identify and categorize hillslopes with similar static characteristics, hydroclimate, land surface processes, and subsurface dynamics in a mountainous watershed – the East River – located in the headwaters of the Upper Colorado River Basin. The ΔP clustering performs very well in identifying hillslopes with six out of the nine characteristics studied. The variability among clusters as quantified by the coefficient of variation (0.2) is less in the ΔP and the machine learning approaches than in the others (> 0.3 for TWI, elevation, and land cover). We further demonstrate the robustness of the ΔP clustering by testing its ability to predict hillslope responses to wet and dry hydrologic conditions, of which it performs well when based on average conditions.
Semi-automatic mapping of shallow landslides using free Sentinel-2 and Google Earth Engine
Authors: Notti Davide , Cignetti Martina , Godone Danilo , Giordan Daniele
Published: July 2022

Abstract. The global availability of Sentinel-2 data and the widespread coverage of free-cost and high-resolution images nowadays give opportunities to map, at low-cost, shallow landslides triggered by extreme events (e.g. rainfall, earthquake). A rapid and low-cost shallow landslides mapping could improve damages estimations, susceptibility models or land management. This work presents a semi-automatic methodology to map potential landslides (PL) using Sentinel-2 images, and it is the first step toward more detailed mapping. We create a GIS-based and user-friendly methodology to extract PL based on pre- post- event NDVI variation and geomorphological filtering. The semi-automatic inventory was compared with benchmark landslides inventory drawn on high-resolution images. We also used the Google Earth Engine scripts to extract the NDVI time series and make a multi-temporal analysis. We apply this to two study areas in NW Italy hatted in 2016 and 2019 by extreme rainfall events. The results show that the semi-automatic mapping based on Sentinel-2 allows detecting the majority of shallow landslides larger than satellite ground pixel (100 m2). PL density and distribution well match with the benchmark. However, the false positives (30 % to 50 % of cases) are challenging to filter, especially when they correspond to river bank erosions or cultivated land.
Technical note: On seasonal variability of the M2 tide
Authors: Ray Richard D.
Published: July 2022

Abstract. Seasonal variability of the M2 ocean tide
can be detected at many ports, perhaps most.
Examination of the cluster of tidal constituents residing within
the M2 tidal group can shed light on the physical mechanisms
underlying seasonality. In the broadest terms these are astronomical, frictional–advective interactions, and climate processes; some induce annual modulations and some semiannual, in amplitude, phase, or both.
This note reviews how this occurs and
gives an example from each broad category.
Phase conventions and their relationship with causal mechanisms, as well as nomenclature, are also addressed.
Family Microhistory: Genealogical Research in Szentes, Hungary
Authors: Fenyvesi Anna
Published: July 2022

This paper provides an account of the author’s family history in the context of her microhistorical research into the lives of her mostly peasant ancestors living in eighteenth- and nineteenth-century Szentes, a small agricultural town in the middle of the Great Hungarian Plain. After becoming a recognized branch of historical research, in the past decade microhistory has made its way into genealogical research, offering an approach and methodology that allows for the piecing together of information about ancestors even when detailed accounts or documents are missing – either because they were lost or because they never existed in the first place. Such microhistories then offer insight into and provide important details for local social history, results that take family history work well beyond the personal scope.
Elusive Kodály Part I: Searching for Hungarian Influences in US Preschool Music Education
Authors: Chong Angela A.
Published: July 2022

This paper is the first part of two articles exploring whether and how Hungarian music pedagogues have influenced early childhood music education in the United States. Using less-known publications and archived materials, this study moves beyond the well-documented history of the Hungarian pedagogue, Zoltán Kodály’s influence upon American general music education to focus on Kodály’s early childhood concepts, which form the backbone of the Hungarian philosophy of music education. Through the lives and work of the Hungarian and American music educators, Katinka Dániel, Katalin Forrai, Sister Lorna Zemke and Betsy Moll, I delineate a pedigree of distinguished female Kodály protégés professing a passion for Hungarian early childhood music pedagogy that did not mainstream into US preschools. In words spoken by and about these scholar-educators, my research locates the systemic and cultural factors contributing to the challenge of implementing Hungarian musical ideas in US preschools. To round out a description of the elusive Kodály influence on US early childhood music, this analysis also draws upon my own Los Angeles experience in searching for a quality Kodály education for my young toddlers.
La producción científica académica en archivística en España sobre temas relacionados con la tecnología digital (2001-2018)
Authors: Roncaglio Cynthia , Carmona Concepción Mendo
Published: July 2022

Objetivos. Identificar y analizar la producción científica en España, cubriendo disertaciones y tesis con temas que abordan la relación entre archivos, archivística y tecnología digital. Encuestas de investigación realizadas a nivel de posgrado, incluyendo disertaciones y tesis.Métodos. La investigación es de naturaleza exploratoria, descriptiva y analítica. El estudio consistió en un análisis cuantitativo y cualitativo de disertaciones y tesis publicadas entre 2001 y 2018, disponibles en los repositorios de universidades en España, luego organizados por categorías de análisis.Resultados. Los TFM identificados en el período de análisis se dividen en solo dos categorías: influencias mutuas entre archivos, archivística y tecnología digital; y retos teóricos y prácticos. Las tesis identificadas se dividen en tres categorías de análisis: relaciones entre archivos, archivística y tecnología digital; influencias mutuas entre archivos, archivística y tecnología digital; y retos teóricos y prácticos. Cabe destacar la gran cantidad de tesis en la segunda categoría mencionada, en comparación con las otras dos. Aunque se observan algunos trabajos más teóricos sin embargo es curioso que no haya ningún estudio de caso.Conclusiones. Hay pocos estudios sobre los cambios teóricos y metodológicos de la disciplina o sobre los retos profesionales. Si embargo, es evidente la creciente e irreversible aplicación de las tecnologías de la información y de la comunicación en la administración y en los archivos, lo que apunta a la necesidad de llenar vacíos en la producción archivística española.
La representación de la migración en el fotoperiodismo contemporáneo: estudio de caso de El abrazo
Authors: Limón Serrano Nieves
Published: July 2022

La cobertura gráfica de la migración es una constante en la prensa española de los últimos años dada la actualidad noticiosa vinculada con estos movimientos humanos. Esta investigación explora la capacidad de la imagen fotográfica para el retrato de las personas migrantes y cómo se produce este tratamiento gráfico. Para ello se centra en el estudio de caso de la fotografía tomada en 19 de mayo de 2021 por Bernat Armangue en la playa de El Tarajal (Ceuta) que muestra el abrazo entre la cooperante de Cruz Roja España, Luna Reyes, y el senegalés, Abdou. Este documento fotográfico impactó en la opinión pública nacional e internacional y tuvo gran difusión en redes sociales. Usando un protocolo de análisis que describe y analiza la imagen en cinco niveles (contextual, compositivo, morfológico, enunciativo y global), la presente investigación nos aproxima a la capacidad del fotoperiodismo para aglutinar en representaciones muy concretas conflictos muy complejos movilizando así a la opinión pública. La polémica asociada a la difusión de esta imagen nos permitirá también explorar cuestiones vinculadas con la ética y la deontología de la profesión fotoperiodística sobre todo cuando se desarrolla en entornos digitales

Published: July 2022

Entre 1909 y 1939 Barcelona vivió el desarrollo del oficio de reportero gráfico en un contexto de evolución y consolidación del fotoperiodismo, que culminó durante la II República y tuvo en la Guerra Civil el momento de máximo esplendor. Un legado ingente del cual una parte se ha conservado hasta hoy. Este artículo se centra en los autores, características y condiciones de accesibilidad de los fondos más importantes custodiados por diferentes archivos públicos.
El archivo histórico del antiguo hospital neuropsiquiátrico de Arezzo: breves instrucciones de uso en clave educativa para profesionales de la salud y del cuidado
Authors: Orefice Carlo
Published: July 2022

La Universidad de Siena conserva el archivo histórico del antiguo hospital neuropsiquiátrico de Arezzo (1901-1990) con el objetivo de preservar, reorganizar, estudiar y mejorar el material (administrativo, sanitario, audiovisual, iconográfico) presente. El artículo reflexiona sobre el posible "uso educativo" de esta pluralidad de materiales y sobre la necesidad de que el Archivo se siga definiendo como un espacio de investigación-intervención multidisciplinar para todos aquellos sujetos (especialmente profesionales de la salud y del cuidado) interesados ​​en conocer y explorar la relación entre la enfermedad mental y el internamiento en un hospital psiquiátrico.
Històries del Punt: memoria oral y archivos menores para una historia desde abajo del Mataró industrial.
Authors: Barreiro González María Soliña , Fernàndez-Aragonès Aina
Published: July 2022

Històries del Punt es un proyecto documental y comunitario para la valorización de la memoria de la clase trabajadora de Mataró (Barcelona) a través de la recuperación y reutilización de fuentes consideradas tradicionalmente menores para la historia y el audiovisual (fotografías amateurs, imágenes de la televisión local, filmes industriales y memoria oral). Su objetivo es construir un "lugar de memoria" para una ciudad donde el 90% de la población vivió directa o indirectamente de la industria textil y que hoy tan sólo ha escrito su historia tecnológico-política. El proceso de desarrollo del proyecto ha llevado también a la configuración de una concepción de la memoria desde lo colectivo y desde lo habitualmente poco enunciado. Esto ha permitido redescubrir no sólo fuentes, sino hechos históricos desconocidos como una red de aborto clandestina, pequeños sabotajes, redes solidarias, trabajo en negro, psicología de la migración, de la maternidad… y, sobre todo, poner en valor una experiencia material compartida desde la heterogeneidad de la clase trabajadora de la ciudad.

El proyecto de “Herencia Latente” está enmarcado dentro del “Festival Robert Capa estuvo aquí 2021”. Consiste en la recopilación, digitalización, catalogación y difusión de las fotografías que conservan los ciudadanos en sus casas, álbumes familiares… El objetivo principal es la creación de un repositorio de imágenes de acceso público para la investigación de los fondos. Como objetivo secundario se centra en dar conocimientos básicos de conservación a los participantes para que su material fotográfico no se pierda en el transcurso de los años. Los resultados obtenidos son 270 fotografías procedentes de 10 participantes. Más de 1100 fotografías de donaciones realizadas por tres personas. Una baja participación por parte de los interesados. Se plantean nuevas formas de actuar desde el estudio de la memoria diaria del proyecto y la implementación del proyecto en nuevos centros en los próximos meses.

This work studied the fumigant toxicity of free and encapsulated rosemary (Rosmarinus officinalis) essential oils against adults of the saw-toothed grain beetle (Oryzeaphilus surinamensis) for three storage periods: 30, 45 and 60 days. Chitosan was used as encapsulation matrix. GC/MS analysis results showed that camphor and 1,8-cineole were the major components with respectively 18.04% and 39.67%. Mortality rates caused by the essential oils at 300 µL/L air after 10 days of storage were about 85.48%. The median lethal concentration (LC50) was 124.80 µL/ L air. Encapsulation efficacy was 25.8% and loading capacity was 1.9%. Encapsulated essential oils achieved an efficacy of 82%, 100% and 100% respectively after 30, 45 and 60 days of storage. Reference treatment with Phosphine revealed a toxicity of 100%, 96% and 71% after 30, 45 and 60 days of storage respectively. Results showed that encapsulated essential oils caused a very slight modification on semolina properties. Protein contents decreased at the end of the storage period less than 1% (from 13.61% after 30 days to 12.91% after 60 days of storage). Encapsulated essential oils might be considered as an alternative fumigant control way for semolina without deterioration of its quality during storage.
A Study on Improving Bioavailability of Paclitaxel through different Novel Drug Delivery Approaches
Authors: Bose Preeta , Kr De Pintu , Bhattacharya Muniraj , Jana Abhishek
Published: July 2022

Paclitaxel (PTX) obtained from the bark of Taxus brevifolia (Pacific yew tree) is a well-known potent drug used for treatment of breast, lung and ovarian cancer. PTX is stated to be a novel antimicrotubule agent. PTX acts by assembling the microtubule from tubulin dimmers and stabilizing of microtubules by prevention of polymerization. Thus it affects the cell division of the cancer cells by interrupting the spindle formation. PTX on application in cancer treatment it shows to have low aqueous solubility use of vehicles like Cremophore EL and ethanol, which on application shows hypersensitivity reaction. So to reduce the toxicity due to these vehicles three main dosage forms are seen to be developed for application of PTX in chemotherapy by researchers throughout the world. Namely; Nano-Particle Approaches, Liposomal approach, Solid Dispersion approach. Nanoparticles are utilized for purposes like decreasing toxicity and minimizing adverse effects of drug molecules and enhancing drug release. Liposomes are capable of containing more amount of PTX and are capable of long term stability, toxicity reduction when compared to other dosage form. Solid dispersions are more effective compared to other methods of particle size reduction to improve the drug solubility. So it can be stated that developing dosage forms like these for reduction of toxicity and efficacious application of PTX in chemotherapy is important.

Published: July 2022

The issue of the ways to preserve and strengthen an individual’s mental health and the effective means of promoting his/her psychological well-being and life satisfaction is a new and promising area of research in modern psychology. The article presents an empirical analysis of personal resources; their development is the basis of an individual’s psychological well-being and effective functioning, when he/she can realize his/her potential, overcome life’s difficulties effectively and work productively. In this context, the correlations of the components of psychological well-being with self-determination abilities, coping strategies and actual abilities were analysed. The inner orientation, which had the greatest impact on the prognostic model of psychological well-being, correlated with awareness of the meaning of one’s own life, understanding of life goals, and the belief in the ability to achieve them. The primary actual capabilities, which determined emotional experiences in relation to oneself and in interpersonal relationships, correlated with almost all examined indicators. The linear regression analysis that was conducted showed that the primary actual capabilities, namely, hope, love, trust, and time are of special importance in an individual’s achieving one’s positive life priorities.

Published: July 2022

Purpose: This review deals with complex relationship among diet, nutrition and their implications on oral health and this review also reveals the oral diseases are associated with considerable pain, anxiety and impaired social functioning. Search method: An electronic search was done in the google website, PubMed, and google scholar. Articles from 1993 to 2017 were included in the review. Summery and Conclusions: Mouth being a reflecting mirror of general health often helps in early diagnosis of many diseases and disturbances. Like any other system of our body, In this way nutrition and oral health are mutually dependent and hence an extensive understanding of this inter relationship is essential for healthy life the customary allowance of food and drink taken by any person per day varies from nutrition, which involves the metabolic processes and utilization of nutrients in the food. Malnutrition affects the oral health and a poor oral health in turn, may lead to malnutrition. Malnutrition may alter the homeostasis, which can lead to disease progression of the oral cavity, reduce the resistance to the microbial biofilm and reduce the capacity of tissue healing. A poor diet was significantly associated with increased odds of oral disease. Dietary advice for the prevention of oral diseases has to be a part of routine patient education practices. Inconsistencies in dietary advice may be linked to inadequate training of professionals. Literature suggests that the nutrition training of dentists and oral health training of dietitians and nutritionists is limited. Keywords: Dietary, dental caries, Malnutrition, Oral manifestations and nutrient deficiency
