Published: July 2020

Undifferentiated pleomorphic sarcoma is a high-grade malignant tumour, accounting for one-third of all primary cardiac sarcomas. This paper describes a case of undifferentiated pleomorphic sarcoma in an infant using detailed morphological characterisation, immunohistochemical examination and a brief literature review. Taken together, these data will be useful not only for practicing pathologists but also for researchers of other biomedical fields for the development of procedures for differential diagnoses, investigation of the pathogenesis and development of therapeutic approaches for undifferentiated pleomorphic sarcoma.Received 4 February 2019.

Physiological or pathological hypertrophy of athlete’s heart syndrome
Authors: Gorbenko A. , Skirdenko Yu. , Nikolaev N. , Zamahina O. , Sherstyuk S. , Ershov A.
Published: July 2020

Intense physical activity increases the risk of sudden death by 10–17 fold. Some of the most important tasks of modern pathophysiology in sports medicine include searching for factors that allow an athlete’s body to adapt to loads, understanding the line between adaptation and pathology and identifying risk groups of adaptation failure. It is necessary to distinguish between hypertrophic cardiomyopathy and true myocardial hypertrophy in athletes that results from the adaptation of the cardiovascular system to intense physical exertion. In Seattle, the American Medical Society of Sports Medicine together with the European Society of Cardiology proposed standards for the interpretation of electrocardiogram in athletes and considered criteria for the detection of pathological changes. The best functional state of an athlete and the effectiveness of his/her training are noted with high autonomy and high variability of heart rate. This is reflected in rhythmocardiogram data by increases in high frequency and root mean square of successive differences in heartbeats and a decrease in the low-frequency to high-frequency ratio.A promising direction in the study of markers of an athletic heart is the analysis of echocardiographic (EchoCG) images of young and professional athletes. According to EchoСG analysis, nonadaptive remodelling is the loss of the ellipsoid shape of the left ventricle in favour of a spherical one. In athletes, when assessing transmitral flow by EchoCG, a low A peak can be considered a reserve of adaptive capabilities of the heart and not a pathology. For athletes-dischargers, a concentric variant of changing the geometry of the myocardium is characteristic. Upon reaching the qualification of a candidate, master of sportsan eccentric change in the left ventricle cavity prevails.Funding: The study did not have sponsorship.Conflict of interest: Authors declare no conflict of interest.Author contributionsConception and design: Y.P.

Quality Evaluation of English Mobile Applications for Gestational Diabetes: App Review using Mobile Application Rating Scale (MARS)
Authors: Kalhori Sharareh R. Niakan , Hemmat Morteza , Noori Tayebe , Heydarian Saeede , Katigari Meysam Rahmani
Published: July 2020

Background:

Mobile applications and social media serve their users as convenient tools to
improve and monitor diseases and conditions such as pregnancy. These tools also exert a positive impact
on Gestational diabetes mellitus (GDM) self-management.

Introduction:

Despite the expansion of mobile health apps for the management of GDM, no study has
evaluated these apps using a valid tool. This study aimed to search and review the apps developed for
this purpose, providing overall and specific rating scores for each aspect of MARS.

Methods:

Two cases of app stores (IOS and Google Play) were searched in January 2019 for apps related
to GDM. Search keywords included “gestational diabetes”, “pregnant diabetes”, and “Health
apps”. Eligibility criteria include: capable of running on Android or IOS operating systems, in the English
language, especially for GDM, and available in Iran. After removal of duplicates, the apps were reviewed,
rated, and evaluated independently by two reviewers with Mobile App Rating Scale (MARS)
tools.

Results:

Initially, 102 apps were identified after the exclusion process, five selected apps were downloaded
and analyzed. All apps were classified into four categories according to contents and their interactive
capabilities. In most quadrants of MARS, the Pregnant with Diabetes app received the highest
scores. Also, in general, the maximum app quality mean score belonged to Pregnant with Diabetes (3.10
/ 5.00).

Conclusion:

Findings revealed that apps designed for GDM are small in number and poor in quality
based on MARS tools. Therefore, considering pregnant women’s need for using the capabilities of these
apps in pregnancy management and promoting community-based care, it seems essential to develop and
design a series of high-quality apps in all four specified categories (only giving comments, obtaining
data and giving comments, diagnosis of GDM, and diet calculator).
A Systematic Review and Meta-analysis on Efficacy of Exercise on Posture and Balance in Patients Suffering from Diabetic Neuropathy
Authors: Thukral Neerja , Kaur Jaspreet , Malik Manoj
Published: July 2020

Background:

Peripheral neuropathy is a major and chronic complication of diabetes mellitus
affecting more than 50% patients suffering from diabetes. There is the involvement of both large and
small diameter nerve fibres leading to altered somatosensory and motor sensations, thereby causing impaired
balance and postural instability.

Objective:

The aim of this study is to assess the effects of exercises on posture and balance in patients
suffering from diabetes mellitus.

Method:

Mean changes in Timed Up and Go test (TUGT), Berg Balance Scale and Postural Sway
with eyes open and eyes closed on Balance System were primary outcome measures. RevMan 5.3 software
was used for the meta-analyses. Eighteen randomized controlled trials met the selection criteria
and were included in the study. All the studies ranked high on the PEDro Rating scale. The risk of bias
was assessed by the Cochrane collaboration tool of risk of bias. Included studies had a low risk of bias.
Sixteen RCT’s were included for the meta-analysis.

Result:

Results of meta-analysis showed that there was a statistically significant improvement in
TUGT with p≤ 0.05 and substantial heterogeneity (I2 = 84%, p < 0.00001) in the experimental group as
compared to control group. There was a statistically significant difference in Berg Balance Scale scores
and heterogeneity of I2 = 62%, p < 0.00001 and significant changes in postural stability (eyes open heterogeneity
of I2 = 100%, p =0.01 and eyes closed, heteogeneity I2 = 0%, p =0.01). Sensitivity analysis
causes a change in heterogeneity.

Conclusion:

It can be concluded that various exercises like balance training, core stability, Tai-Chi,
proprioceptive training, etc. have a significant effect on improving balance and posture in diabetic neuropathy.
Screening of Antibiotics Against β-amyloid as Anti-amyloidogenic Agents: A Drug Repurposing Approach
Authors: Alam Jahangir , Jaiswal Varun , Sharma Lalit
Published: July 2020

Background:

β-amyloid (Aβ) production and aggregation are the main culprits of
Alzheimer’s disease (AD). There is no treatment available for halting the disease progression. Antibiotics
are used not only to treat infections but also to some of the non-contagious diseases and
have found active as anti-amyloidogenic agents.

Objective:

The aim of this work is to investigate anti-amyloidogenic activity of antibiotics as repurposing
agents via inhibiting Aβ aggregation and fibril formation employing in silico and in vitro
approaches.

Mehtods:

In silico screening was designed with receptor and ligand preparation, grid formation,
docking simulation and its analysis. Thioflavin T-amyloid binding and protease-digestion studies
were intended as in vitro assays. These methods assessed the pharmacological potential of antibiotics
as anti-amyloidogenic agents.

Results:

Paromomycin and Neomycin were identified with a higher order of estimated free energy
of binding in in silico experiments. In in vitro screening, paromomycin significantly (p<0.01) reduced
the fluorescence intensity and resistance to tryptic degradation of Aβ(1-42) peptides while
neomycin had no or little effect (p<0.01) when compared to control. Results from docking and wet
lab studies were found in correlation.

Conclusion:

Paromomycin exhibited higher anti-Aβ aggregating and defibrillogenic activity than
neomycin and left an indication for further in vivo testing and could be a future promising antiamyloidal
candidate for the treatment of several amyloidoses.
Crowdsourcing as a Social Interaction Tool to Stimulate Sustainable Transportation Mode Use
Authors: Chandra Shailesh , Kumar Vinay
Published: July 2020

Background:

In this paper, a crowd-based social interaction framework is developed to assess the potential increase in the use of sustainable transportation modes – such as walking, bicycling and public transit.

Methods:

The empirical data were used to validate mode shift behaviors for 77 participants from California State University Long Beach. Data collection spanned over two phases, Phase I followed by Phase II. Each study phase lasted a month. Participants used one of the four modes – personal car, walking, bicycling and public transit - to arrive at the university campus. During Phase I, a control group was created, and individual mode choice of participants were obtained. Individual participants in Phase II were assigned short-encrypted distinct names and were asked to post a daily comment on the quality of experience using the mode that was used to arrive at the campus. The participants were asked to post the comments over a “Twitter” page that was used as the crowdsourcing platform for this study. The encrypted name masked the individual identity of the user. Analysis at the end of Phase II showed that there was an overall mode-shift of almost 19% of personal car users to other sustainable modes of walking, bicycling and transit.

Results:

Results show very important policy implications of using crowdsourcing as a social interaction tool to influence mode choice behavior of commuters, especially among college students and young adults.

Conclusion:

A crowd-based social interaction framework is developed to assess potential increase in the use of sustainable transportation modes – such as walking, bicycling, and public transit. Results showed that providing advanced information on traffic and parking problems can result in a mode shift to active transportation modes.

Authors: Pattiserlihun Alvama , Setiadi Stephanie Jessy James
Published: July 2020

Blended-Flipped Classroom Learning is a learning method that combines blended learning with flipped classroom learning. This study aims to: (1). Design and implement Blended-Flipped Classroom Learning with the topic of Photoelectric Effect for Physics and Physics Education students in Modern Physics course; (2). Determine how the effect of Blended-Flipped Classroom Learning on student learning outcomes for the topic of Photoelectric Effect; (3). Determine students’ responses toward Blended-Flipped Classroom Learning for the topic of Photoelectric Effect. This research was descriptive and conducted at the Physics and Physics Education Department, Universitas Kristen Satya Wacana in the Modern Physics course. From the results of the research conducted it can be concluded that student learning outcomes after Blended-Flipped Classroom Learning were in the “high” and “very high” category, where most students (85.7%) were in the very high category. This result indicates that learning using Blended-Flipped Classroom Learning helps students to achieve optimal learning outcomes. Student responses to Blended-Flipped Classroom Learning were in the “good” category. It also shows that students' positive responses to the learning process can influence the optimization of their learning outcomes. This kind of learning model requires the teacher who acts as a facilitator, dynamist, evaluator and also justifier.

Efecto de fertilización y peso del cormo sobre la multiplicación de semilla de bananito (Musa AA
Authors: Patiño-Martínez Andrés Alfonso , Rodriguez-Yzquierdo Gustavo Adolfo , Miranda-Salas Tatiana Camila , Lemus-Lemus Luz Marina
Published: July 2020

El bananito es el único diploide comestible del grupo acuminata y es apetecido en diferentes escenarios comerciales. Sin embargo, la disponibilidad y el acceso a semilla con calidad es escasa en la zona cafetera, donde se produce principalmente este clon. Un mecanismo para aumentar la oferta de este clon es a través de la multiplicación de plántulas en cámaras térmicas. Para ello, se evaluaron diferentes rangos de peso del cormo y el uso de la fertilización, para establecer condiciones de manejo para obtener material vegetal con atributos de calidad. Se seleccionaron 10 tratamientos producto de la combinación de dos factores (fertilización y peso del cormo); T1: con fertilización, cormo 50-100g; T2: con fertilización, cormo 100-200g; T3: con fertilización, cormo 200-300g ;T4: con fertilización, cormo 300-700g; T5: con fertilización, cormo 700-1.000 g; T6: sin fertilización, cormo 50-100g; T7: sin fertilización, cormo 100-200g; T8: sin fertilización, cormo 200-300g; T9: sin fertilización, cormo 300-700g y T10: sin fertilización, cormo 700-1.000 g. Se evaluaron variables de crecimiento y desarrollo (altura del colino, grosor del pseudotallo y número de hojas). Con los resultados obtenidos en 6 semanas de evaluación se encontró que el principal efecto se produjo por el peso del cormo, donde a pesar de que en todas las plántulas hubo buen comportamiento, los cormos con pesos ≥300g presentaron los mejores valores para las variables evaluadas. Esta información, entrega a los productores algunos criterios importantes implementar un proceso de multiplicación de semilla ya sea para autoabastecimiento o como una posible opción de negocio.

Published: July 2020

BACKGROUND

The patient monitor (PM) is one of the most commonly used medical devices in hospitals worldwide. PMs are used to monitor patients’ vital signs in a wide variety of patient care settings, especially in critical care settings, such as intensive care units. An interesting observation is that the design of PMs has not significantly changed over the past 2 decades, with the layout and structure of PMs more or less unchanged, with incremental changes in design being made rather than transformational changes. Thus, we believe it well-timed to review the design of novel PM interfaces, with particular reference to usability and human factors.

OBJECTIVE

This paper aims to review innovations in PM design proposed by researchers and explore how clinicians responded to these design changes.

METHODS

A literature search of relevant databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, identified 16 related studies. A detailed description of the interface design and an analysis of each novel PM were carried out, including a detailed analysis of the structure of the different user interfaces, to inform future PM design. The test methodologies used to evaluate the different designs are also presented.

RESULTS

Most of the studies included in this review identified some level of improvement in the clinician’s performance when using a novel display in comparison with the traditional PM. For instance, from the 16 reviewed studies, 12 studies identified an improvement in the detection and response times, and 10 studies identified an improvement in the accuracy or treatment efficiency. This indicates that novel displays have the potential to improve the clinical performance of nurses and doctors. However, the outcomes of some of these studies are weakened because of methodological deficiencies. These deficiencies are discussed in detail in this study.

CONCLUSIONS

More careful study design is warranted to investigate the user experience and usability of future novel PMs for real time vital sign monitoring, to establish whether or not they could be used successfully in critical care. A series of recommendations on how future novel PM designs and evaluations can be enhanced are provided.
Virtual Care for Indigenous Populations in Canada, the United States, Australia, and New Zealand: Protocol for a Scoping Review (Preprint)
Authors: Camp Pat , Girt Mirha , Wells Alix , Malas Adeeb , Peter Maryke , Crosbie Stephanie , Holyk Travis
Published: July 2020

BACKGROUND

Indigenous people in Canada, the United States, Australia, and New Zealand experience an increased burden of chronic diseases compared to non-Indigenous people in these countries. Lack of necessary services and culturally relevant care for Indigenous people contributes to this burden. Many Indigenous communities have implemented systems, such as virtual care, to improve chronic disease management. Virtual care has extended beyond videoconferencing to include more advanced technologies, such as remote biometric monitoring devices. However, given the historical and ongoing Western intrusion into Indigenous day to day life, these technologies may seem more invasive and thus require additional research on their acceptability and utility within Indigenous populations.

OBJECTIVE

The objective of this paper is to present the protocol for a scoping review, which aims to map existing evidence. This study is based on the following guiding research question: What are the characteristics of virtual care use by Indigenous adult populations in Canada, the United States, Australia, and New Zealand? The subquestions are related to the technology used, health conditions and nature of the virtual care, cultural safety, and key concepts for effective use.

METHODS

This scoping review protocol is informed by the methodology described by the Joanna Briggs Institute and is supplemented by the frameworks proposed by Arksey and O’Malley and Levac et al. A search for published and gray literature, written in English, and published between 2000 and present will be completed utilizing electronic databases and search engines, including MEDLINE, CINAHL, Embase, Indigenous Peoples of North America, Australian Indigenous HealthInfoNet, Informit, and Native Health Database. Search results will be uploaded to the review software, Covidence, for title and abstract screening before full-text screening begins. This process will be repeated for gray literature. Upon completion, a data abstraction tool will organize the relevant information into categorical formations.

RESULTS

The search strategy has been confirmed, and the screening of titles and abstracts is underway. As of October 2020, we have identified over 300 articles for full-text screening.

CONCLUSIONS

Previous reviews have addressed virtual care within Indigenous communities. However, new virtual care technologies have since emerged; subsequently, additional literature has been published. Mapping and synthesizing this literature will inform new directions for research and discussion.

Syllable structure and prosodic words in Early Old French
Authors: Rainsford Thomas M.
Published: July 2020

This paper presents a comprehensive analysis of the phonotactics of syllable rhymes based on all unique tokens in two Early Old French texts. Based on the data from this single, conservative variety, I develop Jacobs’ (1994) proposal that the Old French stress rule is underlyingly trochaic and that word-fiinal stress is caused by the presence of an empty-headed final syllable. I argue that this analysis can only be valid while words with final stress systematically end in a consonant that can, and often must, be parsed as the onset to an empty-headed syllable. Although this is not the case in most later varieties of Old French, the prediction is borne out by our data. I conclude by examining the implications of this analysis for the accentuation and phonotactics of monosyllables and for the study of prosodic change in Old French.
Evaluando la toxicidad de nanomateriales en modelos celulares tridimensionales
Authors: Juárez-Moreno Karla , Angüis Delgado Kathya , Palestina Romero Brenda , Vazquez Duhalt Rafael
Published: July 2020

Las evaluaciones in vitro para determinar el efecto citotóxico de los nanomateriales en cultivos celulares se han realizado de forma tradicional en cultivos bidimensionales. Esto se debe a que dichos protocolos se han adecuado a partir de aquellos utilizados en la toxicología. Sin embargo, las interacciones entre las células son mucho más complejas que las observadas en un arreglo en monocapa, siendo ésta la principal razón por la que, desde hace algunos años, se promueve la implementación de los cultivos celulares tridimensionales, a los que se les conoce como esferoides, para ser usados en las evaluaciones del efecto de los nanomateriales en cultivos celulares. Cada vez son más las evidencias que soportan la idea de que los esferoides representan un mejor modelo para el estudio de las respuestas celulares, pues emulan con mayor precisión las uniones celulares, comunicación y fisiología que sucede en un tejido dentro de un modelo in vivo. En este artículo, presentamos algunos puntos sobre el desarrollo de los cultivos 3D como una nueva y mejor metodología para las evaluaciones nanotoxicológicas.

El rol de la función de transferencia de contraste en la formación de imágenes de resolución atómica de nanopartículas
Authors: Angeles Chávez Carlos
Published: July 2020

Los resultados de microscopia electrónica de transmisión de alta resolución pueden ser cuantitativamente interpretados si se realizan los ajustes necesarios de la óptica-electrónica del instrumento para la adquisición de las imágenes de resolución atómica. En el marco de este trabajo se describe cualitativamente los principios de la formación de imágenes en términos de la difracción de electrones y óptica electrónica. Al final del proceso se resume a la función de transferencia de contraste (FTC) y desenfoque de la imagen del objeto. La manipulación cuidadosa del desenfoque permite controlar la FTC para conseguir contraste de fase más fuerte de los espaciados interplanares de la red cristalina de la partícula bajo estudio. El contraste que se puede lograr es brillante u oscuro en el lado del desenfoque negativo antes del valor de desenfoque de Scherzer. Contrastes oscuros de clusters de WOx sobre contraste brillantes de la red m-ZrO2 pudo ser evidenciado a través de la manipulación controlada y  precisa del desenfoque.

Resolución atómica de elementos ligeros utilizando HAADF y ABF-STEM con corrección de Cs y bajo voltaje
Authors: Esparza Muñoz Rodrigo
Published: July 2020

Microscopía electrónica de transmisión/barrido (STEM) ofrece información estructural y química del orden de 0.1 nm de resolución espacial, tal resolución es llevada a cabo mediante el corrector de aberración esférica. En el STEM, un haz de electrones es enfocado y escaneado sobre la muestra, por lo que la imagen es formada midiendo la señal electrónica que surge después de las interacciones electrones-muestra. La señal de los electrones dispersados puede ser empleada para obtener imágenes de campo claro y campo obscuro. El microscopio STEM es un poderoso instrumento para estudiar las propiedades físicas de las nanoestructuras, que requieren de un análisis estructural y químico a nivel atómico. Por lo tanto, STEM es una técnica capaz de identificar la posición de los átomos y las columnas atómicas. En este trabajo, los parámetros instrumentales básicos del microscopio antes de sus aplicaciones fueron evaluados. Además, imágenes experimentales de campo oscuro anular de alto ángulo (HAADF)-STEM y campo claro anular (ABF)-STEM de una muestra de LaAlO3 fueron obtenidas a bajos voltajes de operación y comparadas con imágenes simuladas obtenidas con el método de multicapas. Se encontró que las imágenes simuladas coinciden bien con las imágenes experimentales.
En torno al Derecho provincial romano y el caso griego
Authors: Pérez Carrandi Juan
Published: July 2020

El Derecho romano apenas se extenderá, de forma tardía además, por Italia, a través de la concesión generalizada de ciudadanía a los itálicos. En cambio, en las provincias Roma restringe absolutamente la política de concesiones, tendiendo a respetar el interno desenvolvimiento de los diferentes pueblos una vez estos son sometidos, pues se prioriza casi exclusivamente la tributación de los mismos. De este modo, los Derechos locales se respetan generalmente, si bien la inercia de la interacción podría indicar destellos de algún tipo de sincretismo que, si se dio, fue muy tardíamente y favorable, lógicamente, a la fuerza ocupante. Este escenario es mayormente planteable para la parte occidental del imperio, pues Grecia y, por extensión, el resto de oriente, muy helenizado, vivirán una tenue romanización cultural, siendo en Derecho romano aún más extraño en un área que siempre gozaría en la etapa romana de un plus de autonomía.
“Ciencia Jurídica”, Interdisciplinariedad y Ley de Hume: a propósito de un texto de Francisco Carpintero
Authors: Gómez Martínez Diego León
Published: July 2020

En este artículo se pretende reflexionar sobre algunos aspectos del discurso de la “ciencia jurídica”, la teoría y el método jurídicos, en relación con un artículo titulado Métodos científicos y método del derecho: una historia superada de autoría de Francisco Carpintero. En esta dirección de análisis, primero se expondrá brevemente una lectura posible del texto de Carpintero, donde se señalarán unos puntos nodales de su propuesta. Luego se observará el concepto de “ciencia jurídica” y se mostrará una distinción de modelos de “ciencia del derecho” que permiten ver con claridad que es posible la interdisciplinariedad en esta “ciencia” y que, por tanto, negar esta posibilidad obedece a una lectura parcial y comprometida ideológicamente que recae sobre este tipo de discurso. Para esto se tomará en cuenta la distinción entre “ciencia jurídica” normativista y “ciencia jurídica” realista. Posteriormente se observará un punto importante y decisivo en el método de la “ciencia jurídica” que hace referencia a la ley de Hume y a la forma en como Carpintero la encara. Con lo cual se mostrará que su crítica en este punto se hace también con un alto grado de generalización, situación que lo lleva a proponer una lectura ideológica que tiene como consecuencia que sus críticas lleguen tan solo constituir una postura más, con la que incluso no se llegan a superar los asuntos que critica. Finalmente se ofrecerá una conclusión con el fin de hacer notar que la falta de interdisciplinariedad de la “ciencia” y el método jurídicos según Carpintero es una idea imperialista en cuanto a valores epistémicos se trata.
¿Una espada de Damocles? Responsabilidades de servidores públicos y prevención de la arbitrariedad
Authors: Rivero Ortega Ricardo
Published: July 2020

El saber antiguo conocía los riesgos del ejercicio del poder arbitrario y la necesidad de prevenirlos. Las diversas instituciones diseñadas para exigir responsabilidades a las autoridades y funcionarios (desde el juicio de residencia a las vigentes leyes de probidad), han de encontrar un punto de equilibrio entre la indeseable impunidad y la paralización de la toma de decisiones, por temor a sus consecuencias. La responsabilidad política no es suficiente para alcanzarlo, así que necesitamos mecanismos preventivos de la arbitrariedad y un nuevo énfasis en los aspectos subjetivos (personales, humanos) de la responsabilidad.
El reto de la incorporación de herramientas de la Ecología en el marco jurídico de protección del agua dulce. El caso del Noreste de la provincia de Buenos Aires, Argentina
Authors: Minaverry Clara María
Published: July 2020

En este trabajo se plantea la hipótesis de que existe una incipiente relación entre algunas herramientas brindadas por la Ecología que han sido incorporadas exitosamente en determinada normativa ambiental y del agua dulce en Argentina. Y, además el progreso de dicha tendencia podría significar un avance en los marcos jurídicos de protección del agua dulce y es una preocupación de la población del Noreste de la Provincia de Buenos Aires. Sin embargo, la transferencia desde la Ecología hacia el Derecho Ambiental y su aplicación en la práctica podrían ser complejas por las características técnicas de la primera y que son desconocidos por la segunda. En primer lugar, se expondrá la metodología, los conceptos ecológicos (bioindicadores, calidad/salud/equilibrio ecológico de ecosistemas) y el derecho comparado. En segundo lugar, se presentará la normativa y jurisprudencia argentina, aportes científicos brindados a la Administración pública, aspectos psicológicos y emocionales y finalmente se presentarán conclusiones.
El servicio público: ¿instrumento de intervención o método de regulación para la protección de intereses colectivos?
Authors: Castillo Roldán Juan Miguel
Published: July 2020

El concepto de servicio público ha sido, desde siempre, uno de los ejes del Derecho Administrativo, y la irrenunciable necesidad de comprenderlo ha proyectado incontables ponderaciones doctrinales y jurisprudenciales en todo el hemisferio. La interacción entre el mercado y el Estado debería articularse mediante fórmulas claras y viables que logren delimitar aquellos campos sujetos a una razonada y legítima intervención estatal, ya sea por medio del monopolio público para la satisfacción directa de los servicios o de la delegación en manos privadas para la satisfacción indirecta de servicios mediante regulación sectorial. En el libre mercado permiten al Estado desconocer arbitrariamente las libertades de empresa, de asociación y de competencia libre y leal, las cuales constituyen auténticos logros de la evolución del Derecho.

El objetivo de este trabajo es analizar la producción de conocimiento en historia de la educación matemática (HEM) bajo la óptica de las Humanidades Digitales, a partir de tesis de maestría y doctorado realizadas en 2012 y 2017 en Brasil. La muestra está compuesta por 52 tesis y se utilizó el software IRaMuTeQ para el análisis multidimensional de sus resúmenes. El análisis de frecuencia de palabras posibilitó la identificación de temáticas y metodologías; mientras que el análisis factorial de correspondencia posibilitó 1) la contextualización semántica y 2) visualizar las distancias entre los corpus textuales (resúmenes de tesis). En Brasil, la evolución de HEM muestra aumento del número de tesis, diversificación de temáticas y metodologías. En los años analizados la formación de profesores es el principal tema de interés. La hermenéutica de profundidad es el principal referente teórico-metodológico en las tesis de 2017. Los hallazgos evidencian la influencia de los grupos de investigación en las agendas de investigación de las universidades. Los resultados confirman la utilidad de las herramientas de las Humanidades Digitales, específicamente las relativas a la minería de texto, para analizar la evolución de la producción de conocimiento en HEM
