A Política de Mão de Obra em São Paulo e as Políticas Federais de Deslocamento Populacional do Primeiro Governo Vargas
Authors: Tessari Claudia Alessandra , Costa Julio César Zorzenon
Published: January 2023

Este artigo trata da política de mão de obra empreendida pelo primeiro Governo Vargas, estabelecendo relações entre as políticas de âmbito federal e as colocadas a cabo pelo estado de São Paulo. O objetivo é mostrar como a política e a estrutura institucional paulistas relativas ao recrutamento de trabalhadores responderam às políticas federais, inseridas no projeto de Vargas de desenvolvimento voltado para dentro e de integração do mercado interno, e ao papel dado por ele aos deslocamentos populacionais. Nesse sentido, o objetivo é também mostrar que havia intenção do governo central de controlar o mercado de trabalho com o intuito de assegurar o seu equilíbrio e que essas intenções impactaram a política de mão de obra paulista. Os destaques, em âmbito federal, foram o Decreto-Lei n. 406, de 4 de maio de 1938 (BRASIL, 1938), e o Decreto n. 3.010, de 20 de agosto de 1938 (BRASIL, 1938). Com sua implementação, o estado de São Paulo teve de adequar suas instituições relativas ao assunto, criando a Inspetoria dos Trabalhadores Migrantes, de perfil mais estatizante e intervencionista, desmobilizando iniciativas privadas que atuavam no negócio de arregimentação e transporte de trabalhadores brasileiros.

A pandemia do novo coronavírus restringiu, entre tantos aspectos, o acesso às escolas, como medida de enfrentamento para redução do contágio. Dessa forma, este artigo objetivou promover um diálogo sobre os impactos da COVID-19 na educação no ano de 2020, tendo como foco principal uma análise acerca dos desafios e as estratégias legais (em âmbito federal) para garantir o direito à aprendizagem e suas consequências em meio às ações empreendidas durante a pandemia. Trata-se de uma pesquisa documental realizada a partir da análise das legislações educacionais propostas para atender o cenário pandêmico e publicações científicas atuais. Os resultados apontaram que a legislação educacional brasileira direcionou a adoção de estratégias para garantir o direito à aprendizagem através do ensino remoto e que estas, somadas à situação vivenciada, reforçaram o quadro de desigualdade social no país.
A SYSTEMATIC REVIEW OF IOT INTEGRATION ON HEALTH MONITORING SYSTEM
Authors: AlAdwaniª Haitham , ALSiyabiᵇ Zahra
Published: January 2023

The Internet of Things (IoT) has had a significant impact on many
fields, including the healthcare industry. It has, in particular,
resulted in the development of devices that can collect and transmit
data, allowing for better patient monitoring. IoT has enabled remote
patient monitoring and telemedicine, which has significantly improved
care. IoT wearable devices can collect and transmit data on patients’
blood pressure, heart rates, and blood glucose levels. IoT could also
help monitor hand hygiene compliance and track patients’ moods and
depression. Significantly, monitoring the symptoms of Parkinson’s
disease patients via IoT aids in disease management. These IoT
applications have had significant implications in healthcare. IoT
applications reduce healthcare costs while also improving treatment. The
diagnosis becomes timely, allowing timely interventions to be
implemented. IoT also enables proactive treatment and ensures the
effective use and management of drug-related equipment. The main
challenges are data security and the high initial implementation cost.
In general, implementing IoT has had an impact on care delivery and
resulted in better patient outcomes.
Evaluating the representation of tropical stratocumulus and shallow cumulus clouds as well as their radiative effects in CMIP6 models using satellite observations
Authors: Crnivec Nina , Cesana Gregory , Pincus Robert
Published: January 2023

Low clouds over tropical oceans reflect a great proportion of solar
radiation back to space and thereby cool the Earth, yet this phenomenon
has been poorly simulated in several previous generations of climate
models. The principal aim of the present study is to employ satellite
observations to evaluate the representation of marine tropical low
clouds and their radiative effect at the top of the atmosphere in a
subset of latest climate models participating in CMIP6. We strive for
regime-oriented model validation and hence introduce a qualitative
approach to discriminate stratocumulus (Sc) from shallow cumulus (Cu).
The novel Sc-Cu categorization has a conceptual advantage of being based
on cloud properties, rather than relying on a model response to a
cloud-controlling factor. We find that CMIP6 models underestimate
low-cloud cover in both Sc- and Cu-regions of tropical oceans. A more
detailed investigation of cloud biases reveals that most CMIP6 models
underestimate the relative frequency of occurrence (RFO) of Sc and
overestimate RFO of Cu. We further demonstrate that tropical low
cloudiness in CMIP6 models remains too bright. The regime-oriented
validation represents the basis for improving parameterizations of
physical processes that determine the cloud cover and radiative impact
of Sc and Cu, which are still misrepresented in current climate models.

Published: January 2023

Recent studies have advanced our understanding of the clinical, histological and imaging characteristics of congenital haemangiomas (CHs), and have reported possible complications and atypical behaviour. The aim of this study is to describe the clinical, histological and ultrasound features of a series of CHs and to analyse their association with complications and atypical behaviour, with a view to providing diagnostic and management recommendations. The medical records, histology results and ultrasound images of all patients with CH diagnosed in the Dermatology Department of Alicante University General Hospital between 2006 and 2021 were retrospectively reviewed. A total of 18 patients were included, of whom 4 (22.2%) had complications. The most severe was 1 case with heart failure. There was a significant association between large CH size (> 5 cm) and the occurrence of complications (p = 0.019). The study identified 3 different lobule patterns, but found no relationship with CH subtype or other findings. The associations of venous ectasia, venous lakes and arteriovenous microshunts with occurrence of complications was borderline significant (p = 0.055). Study limitations were the small sample and the retrospective analysis. To conclude, haematological and cardiological assessment is indicated in large CHs and should be considered in CHs with ultrasound findings of venous ectasia, venous lakes or arteriovenous microshunts, as these cases present a greater risk of complications.

Headaches associated with exertion and physical activity correspond to primary disorders or secondary to underlying diseases, requiring careful anamnesis and neurological examination, as physiopathological and clinical characteristics coincide in both groups. On primary health care this aspect must be judicious, as the undervaluation of complaints, delay on the diagnosis or failure to timely refer to the emergency department in the face of a serious secondary cause imply a risk to life or serious sequelae. Primary exercise headache has relevant particularities, such as sudden and explosive onset, intensity, or duration longer than usual in relation to the practice of physical exercise. It is important to know the signs of severity, adapt the anamnesis, physical examination, and clinical management for a correct diagnosis and implementation of an effective therapy.

Authors: Affandi Akhmad , Muhalim  , Aeni Nur
Published: January 2023

Amongst four skills tested in IELTS, writing IELTS is considered to be one of the most challenging language skills to master. It is believed that writing for second language learners is arguably the strenuous skill to be used in attaining communicative competence. Therefore, discussing learning strategies and good language learners related to IELTS task 2 using four IELTS assessment criteria is still interesting. Considering the significances of all strategies classification, it can be justified those strategies could be very helpful in Writing IELTS Task 2. Particularly, writing IELTS would be significantly improved by using Cognitive, metacognitive, and affective strategies. The reason is that cognitive strategies relate to practicing as the main regular improvement in writing IELTS, Metacognitive strategies connect to planning and brainstorming, and Affective strategies relate to emotional control including anxiety. However, there are some aspects that have to be considered in order to overcome possible problems and strategic limitations. First, there should be explicit instruction and steps from teachers to apply for all of them. Second, Learner should have a capability to distinguish and choose appropriate strategies.

Published: January 2023

In several developing countries, root and tuber crops play a crucial role in food security as well as in agriculture. Based on production and consumption, sweet potato [Ipomoea batatas (L.) Lam] plays a significant role after potato among the root and tuber crops. Today, sweet potato breeding program focus on multiple purposes. There are four sweet potato breeding platforms (three in Africa) and in SSA there are four breeding centers (three in West Africa). High levels of β‐carotene, phenolics, anthocyanins, vitamins, fiber, dietary, minerals, and other bioactive compounds content depends on the flesh color of sweet potatoes. The orange‐fleshed sweet potato types contain high β‐carotene levels and low dry matter content. White‐cream fleshed color varieties have high dry matter (>30%). The purple‐fleshed sweet potato varieties with attractive color and high anthocyanin content are the most preferred in Asia. Sweet potato with low in sweetness and higher dry matter (28–30%) are the specially of most parts of sub-Saharan Africa. Consuming β‐carotene leads as a viable long‐term food‐based strategy for combating the deficiency vitamin A in the world. The sweet potato dry matter content up of 80-90% carbohydrates and exists in the form of starch and sugars non-starch polysaccharides. The primary contributors to the taste of the sweet potato are sugars and organic acids. The strong flavor and high levels of sweetness may have affected the popularity of sweet potato as a staple food. Due of the negative correlation between traits, breeding for high B-carotene and dry matter with low sugar in one variety has remained a challenge, although it was reported that recurrent mass selection should be possible to accumulate favorable alleles so that progress can be made over.

Published: January 2023

El trabajo revisa la evidencia científica producida durante el periodo 2011-2019 sobre el pensamiento del profesorado chileno y los saberes pedagógicos y disciplinarios, en el contexto del sistema escolar. El periodo 2011-2019 se caracterizó por la implementación de nuevas políticas educativas, esencialmente centradas en la carrera docente, así como por la emergencia de aulas diversas, gatilladas por el fenómeno migratorio y nuevas políticas inclusivas. El trabajo se desarrolló bajo una metodología cualitativa, con un diseño tipo revisión sistemática, propio de un estudio secundario. De acuerdo con los criterios establecidos, se seleccionaron 29 fuentes de información (estudios), cuyos datos fueron organizados en ocho categorías. Los resultados demostraron que en el pensamiento del profesorado chileno cohabitan perspectivas contrapuestas; no obstante, se revela en general una preponderancia de referencias asociadas al constructivismo. Del mismo modo, se apreció una alta valoración del profesorado sobre su propio desempeño, que no necesariamente se podría armonizar con la evidencia de aprendizajes escolares.
 
The thinking of Chilean teachers about pedagogical knowledge: Evidence from the last decade
Abstract
The work aimed to review the scientific evidence produced during the period 2011-2019, on the thinking of Chilean teachers about pedagogical and disciplinary knowledge, in the context of the school system. The period 2011-2019 was characterized in terms of the implementation of new educational policies, essentially focused on the teaching career, and in terms of the emergence of diverse classrooms, triggered by the migration phenomenon and new inclusive policies. The work was developed under a qualitative methodology, with a systematic review design, typical of a secondary study. According to the established criteria, 29 sources of information (studies) were selected, whose information was categorized into eight categories. The results showed that opposing perspectives coexist in the thinking of Chilean teachers; however, the general presence of a preponderance of references associated with constructivism was revealed. Likewise, teachers showed a high valuation of their own performance, which could not necessarily be harmonized with the evidence of school learning.

Significados sobre escritura académica en un curso de actualización docente a distancia
Authors: Guerrero Tejero Irán Guadalupe
Published: January 2023

Diferentes investigaciones han señalado desde hace varias décadas la importancia de examinar las creencias, supuestos y representaciones de los docentes sobre la escritura en la universidad. En menor medida se ha explorado de qué manera se modifican esas ideas. Este trabajo, de corte cualitativo, exploró los significados que un grupo de docentes universitarios atribuye a la escritura académica, antes y después de participar en un curso a distancia. Se emplearon referentes teóricos de la literacidad académica y del análisis del discurso guiado por una perspectiva etnográfica, para analizar los foros, las sesiones virtuales, así como la evidencia escrita producida en el contexto del curso. Los resultados muestran que los docentes reflexionaron y analizaron sus experiencias e introdujeron a su discurso aspectos de socialización y literacidad académica. Esto confirma la necesidad de propiciar espacios de diálogo y reflexión docente para generar ideas alternas sobre estos procesos.
 
Teacher’s meanings about academic writing in a distance in-service teacher education course
Abstract
Research has pointed out for several decades the importance of examining teachers' beliefs, assumptions, and representations about writing in the university. To a lesser extent, the way in which these ideas are modified has been explored. This qualitative work explored the meanings that a group of university teachers attribute to academic writing, before and after participating in a distance in-service teacher education course. Theoretical referents of academic literacy and discourse analysis guided by an ethnographic perspective, were used to analyze the forums, virtual sessions, as well as the written evidence produced in the context of the course. The results show that the teachers reflected and analyzed their experiences and introduced aspects of socialization and academic literacy to their discourse. This confirms the need to promote spaces for dialogue and teacher reflection to generate alternative ideas about these processes.
La planeación en México. Su evolución y efectos en el desarrollo regional.
Authors: Arellano Jiménez Cristóbal , Carrillo Barradas José Luis
Published: January 2023

La planeación del desarrollo en México ha sido una atribución del Estado para organizar territorialmente la economía y las convergencias regionales; como práctica, la planeación institucional ha transitado por un largo período de casi cien años durante los cuales la actuación del Estado aunque activa, no ha sido tan acertada como se comprueba en el desordenado comportamiento de la red urbana nacional con marcadas diferencias territoriales.
La construcción social del riesgo en el medio ambiente urbano: cambio climático y seguridad hídrica en las regiones metropolitanas de Veracruz.
Authors: Pérez Palmeros Alher , Rodríguez Hernández Leonardo Daniel , Martínez Olivarez Pedro
Published: January 2023

"El crecimiento urbano, la presencia de un mayor número de habitantes en las ciudades, la degradación del ambiente y la pérdida de recursos naturales, sumado al aumento en la magnitud y frecuencia de fenómenos hidrometeorológicos extremos producto del cambio climático, incrementan la posibilidad de un desastre en el medio ambiente urbano Es menester de este ensayo describir y conceptualizar la construcción social de riesgos en el medio ambiente urbano desde el papel que cumplen los ecosistemas naturales urbanos en la provisión de servicios ecosistémicos y como la pérdida de éstos incrementa el riesgo de desastre frente a algún fenómeno hidroclimático y eleva los niveles de impactos potenciales al sistema producto de la exposición y el nivel de vulnerabilidad."
Los paisajes de la guerra
Authors: Thiébaut Virginie
Published: January 2023

Este número temático de Ulúa se enfoca a estudiar los aspectos geográficos que pudieron haber influido en los conflictos armados, en especial a través de la noción de paisaje, con toda la dimensión visual que implica. Se trata de entender el desarrollo de ciertos conflictos y los retos que enfrentaron sus actores, tomando en cuenta y dando el peso adecuado a la dimensión espacial, mediante testimonios de la época y descripciones; por ejemplo, cómo los militares, políticos o negociadores percibieron su entorno, a veces conocido, a veces incógnito, extraño y difícil de aprehender en un contexto bélico. Se aborda asimismo el tema de la transformación irremediable o pasajera de los paisajes, causada por los bombardeos y las destrucciones puntuales o masivas, o, al contrario, por las nuevas edificaciones requeridas por causas de guerra, como las fortificaciones. Se estudia también cómo ciertos elementos topográficos ―elevaciones, barrancas, cadenas montañosas― pudieron ser utilizados como lugares de refugio o elementos estratégicos y transformarse incluso en referentes ideológicos a lo largo de los conflictos.
Extraños en tierras (no tan) extrañas: antecedentes, preparativos y reconocimientos de la expedición española a México, 1857-1862
Authors: Vargas Matías Sergio Arturo
Published: January 2023

Resumen:
El presente trabajo se centra en las acciones realizadas por las fuerzas españolas que, como parte de la alianza tripartita, ocuparon el puerto de Veracruz entre finales de 1861 y principios de 1862. Desde esta perspectiva, la investigación refiere la labor de inteligencia realizada por el alto mando hispano en los años previos, que se reflejó en la elaboración de diversos reportes, mapas y planos con la intención de garantizar el éxito en caso de un futuro ataque a la plaza veracruzana. Asimismo, se detallan los reconocimientos geográficos efectuados por el ejército expedicionario durante su estadía en la zona para asegurar el control de la región comprendida entre Veracruz, Xalapa y Orizaba, y en caso necesario, incursionar tierra adentro rumbo a la capital del país, lo cual, como es sabido, finalmente no se llevó a cabo.
Palabras clave: Expedición española de 1862, Veracruz, caminos, reconocimientos geográficos, cartografía.
Las montañas de Las Segovias de Nicaragua. Espacio de lucha irregular, 1927 a 1990
Authors: Mendoza Duarte Yuridia Odalis
Published: January 2023

Resumen:
El objetivo de este artículo es mostrar cómo, desde los años treinta hasta la década de 1980, la región montañosa de Las Segovias fue un espacio estratégico para los guerrilleros de Sandino, para los combatientes del Frente Sandinista de Liberación Nacional y para la contrainsurgencia representada por la Fuerza Democrática Nicaragüense, así como también para los Cachorros de Sandino. El difícil acceso a la montaña y la disponibilidad de recursos en esta región favorecieron a los guerrilleros para que obtuvieran la colaboración de los campesinos. Por otro lado, las formas de combate fueron adaptadas a las condiciones del terreno, es decir, la lucha irregular, la cual no favorecía a las incursiones militares de los ejércitos regulares.
Palabras clave: Montaña de Las Segovias, lucha irregular, Frente Sandinista de Liberación Nacional, Batallones de Lucha Irregular.
La batalla de Cerro Gordo de 1847 desde el Cerro Gordo: algunas reflexiones sobre el uso del análisis del paisaje y el espacio en la explicación de fenómenos bélicos
Authors: García Suárez Mario A.
Published: January 2023

El presente ensayo es un intento por explicar el uso del análisis del paisaje y el espacio como herramienta metodológica alternativa para comprender la batalla de Cerro Gordo (ocurrida en 1847 durante la guerra entre México y Estados Unidos) desde el punto de vista de los hombres que combatieron. El texto se encuentra dividido en tres apartados. En el primero se explican los conceptos de paisaje y espacio y su utilización como herramientas metodológicas y se exponen los elementos geográficos, climatológicos y geológicos de la zona estudiada. El segundo se dedica al paisaje y el espacio y a su empleo como herramientas de interpretación para hablar sobre la multiplicidad de perspectivas desde las que puede verse la batalla, la dimensión del espacio geográfico que se encuentra minimizado por la historiografía y la recreación empírica que busca seguir las huellas de quienes vivieron el hecho. Por último, en el tercero, que funge como conclusión, se trata de reflexionar en torno a la pregunta: ¿los historiadores hemos subestimado el análisis del paisaje y el espacio como herramienta metodológica/interpretativa en nuestro quehacer académico? Con base en esto, se busca subsanar la falta de fuentes militares en la guerra, así como proponer un acercamiento a otras metodologías que enriquezcan el trabajo histórico.

The paper explores traditional medicine beliefs among older Vietnamese persons in the Hoc Mon district. Twenty-two respondents aged 62 to 82 years and nine key informants were recruited. Bourdieu’s theory of practice was used to analyze data through thematic analysis. The main findings explore two models of traditional medicine used in the aging population to control chronic diseases and post-stroke: (1) the switch from western to traditional medicine and (2) the use of both western and traditional medicine. Moreover, traditional medicine use is influenced by beliefs about susceptibility and severity of disease, the pros and cons of traditional medicine, and beliefs about traditional medicine practitioners. This exploratory study may shed more light on the promotion of traditional medicine for health and health management for the aging population in Vietnam.
