Mass of different snow crystal shapes derived from fall speed
measurements
Authors: Vázquez-Martín Sandra , Kuhn Thomas , Eliasson Salomon
Published: March 2021

Abstract. Meteorological forecast and climate models require good knowledge of the microphysical properties of hydrometeors and the atmospheric snow and ice crystals in clouds. For instance, their size, cross-sectional area, shape, mass, and fall speed. Especially shape is an important parameter in that it strongly affects the scattering properties of ice particles, and consequently their response to remote sensing techniques. The fall speed and mass of ice particles are other important parameters both for numerical forecast models and for the representation of snow and ice clouds in climate models. In the case of fall speed, it is responsible for the rate of removal of ice from these models. The particle mass is a key quantity that connects the cloud microphysical properties to radiative properties. Using an empirical relationship between the dimensionless Reynolds and Best numbers, fall speed and mass can be derived from each other if particle size and cross-sectional area are also known. In this work, ground-based in-situ measurements of snow particle microphysical properties are used to analyse mass as a function of shape and the other properties particle size, cross-sectional area, and fall speed. The measurements for this study were done in Kiruna, Sweden during snowfall seasons of 2014 to 2019 and using the ground-based in-situ instrument Dual Ice Crystal Imager (D-ICI), which takes high-resolution side- and top-view images of natural hydrometeors. From these images, particle size (maximum dimension), cross-sectional area, and fall speed of individual particles are determined. The particles are shape classified according to the scheme presented in our previous work, in which particles sort into 15 different shape groups depending on their shape and morphology. Particle masses of individual ice particles are estimated from measured particle size, cross-sectional area, and fall speed. The selected dataset covers sizes from about 0.1 mm to 3.2 mm, fall speeds from 0.1 m s−1 to 1.6 m s−1, and masses from close to 0.2 μg to 320 μg. In our previous work, the fall speed relationships between particle size and cross-sectional area were studied. In this work, the same dataset is used to determine the particle mass, and consequently, the mass relationships between particle size, cross-sectional area, and fall speed are studied for these 15 shape groups. Furthermore, the mass relationships presented in this study are compared with the previous studies.
Gas-particle partitioning of polyol tracers in the western Yangtze
River Delta, China: Absorptive or Henry's law partitioning?

Published: March 2021

Abstract. Gas-particle partitioning of water-soluble organic compounds plays a significant role in the formation and source apportionment of organic aerosols, but is poorly characterized. In this work, gas- and particle-phase concentrations of isoprene oxidation products (C5-alkene triols and 2-methylterols), levoglucosan, and sugar polyols were measured simultaneously at a suburban site of the western Yangtze River Delta in east China. All target polyols were primarily distributed into the particle phase (85.9–99.8 %), and their average particle-phase fractions were not strictly dependent on vapor pressures. Moreover, the measurement-based partitioning coefficients (Kp,OM) of isoprene oxidation products and levoglucosan were 102 to 104 times larger than their predicted Kp,OM based on the equilibrium absorptive partitioning model. These are likely attributed to the hygroscopic properties of polyol tracers and high aerosol liquid water (ALW) concentrations (~20 µg m−3) of the study location. Due to the large gaps (up to 107) between measurement-based effective Henry's law coefficients (KH,e) and predicted values in pure water (KH,w), the gas-particle partitioning of polyol tracers could not be depicted using Henry's law alone either. The regressions of log (KH,w/KH,e) versus molality of major water-soluble components in ALW indicated that sulfate ions (salting-in effect) and water-soluble organic carbon can promote the partitioning of polyol tracers into the aqueous phase. These results suggest a partitioning mechanism of enhanced aqueous-phase uptake for polyol tracers, which partly reveals the discrepancy between observation and modeling of secondary organic aerosols.
An observing system simulation experiment (OSSE)-based
assessment of the retrieval of above-cloud temperature and water
vapor using hyperspectral infrared sounder
Authors: Feng Jing , Huang Yi , Qu Zhipeng
Published: March 2021

Abstract. Measuring atmospheric conditions above convective storms is challenging. This study finds that the uncertainties in cloud properties near the top of deep convective clouds have a non-negligible impact on the TOA infrared radiances which cannot be fully eliminated by adopting a slab-cloud assumption. To overcome this issue, a synergetic retrieval method is developed. This method integrates the infrared hyperspectral observations with cloud measurements from active sensors to retrieve atmospheric temperature, water vapor, and cloud properties simultaneously. Using an observation system simulation experiment (OSSE), we found that the retrieval method is capable of detecting the spatial distribution of temperature and humidity anomalies above convective storms and reducing the root-mean-square-errors in temperature and column integrated water vapor by more than half.
A flexible, open, and interactive digital platform to support online and blended experiential learning environments: Thinglink and thin sections
Authors: Jeffery Adam J. , Rogers Steven L. , Jeffery Kelly L. A. , Hobson Luke
Published: March 2021

Abstract. This study investigates the potential value of, and provides a method for, the
creation of flexible, digital, and asynchronous platforms to create
student-centred materials for use in an online and/or blended learning
environment. We made use of Thinglink to create a “virtual microscope” resource
for geology and associated courses in higher education. This is achieved
through the dissemination of a simple learning resource comprising interactive
imagery and audio. The visual analysis of rocks under the microscope, termed thin-section
petrography, is a fundamental component in geology programmes in higher
education, with key skills which are transferable with other fields such as
material science, biology, and forensic science. However, learning environments
and activities in this field are often dictated by the requirement for access
to microscope facilities and supplementary resources which are highly
variable in their academic level, availability, design, and scale, ranging
from traditional textbooks to online resources. A resource was created which allows individuals to experience some of the
aspects of petrographic microscopy in a digital manner. In particular,
specific features of the materials observed and how microscopes work were
included. The resource was disseminated to a population of learners and
educators, who provided responses to a questionnaire. Responses were
overwhelmingly positive and indicate considerable interest from learner and
teacher alike. Critical areas for improvement include the need for clarity in
the user interface and the inclusion of a recorded human voice rather than
automated text narration. This study highlights the need for, and benefits of,
interactive online learning resources in petrology and associated fields. This
type of resource has positive implications for the flexibility, inclusivity, and accessibility of teaching materials. Such resources may prove particularly
valuable when distance learning is unavoidable (e.g. the COVID-19 crisis)
and/or hybrid, blended learning environments are being deployed. The method
and platform used in this study are highly transferable to other subject areas
(or other areas of the geosciences).

The inquiry is part of the research line: Community Integration, Pedagogy and Evaluation in the training of professionals, with the complex objective of analyzing Freire's work in light of the cries of the South and some solutions to the crisis. From the transcomplex rhizomatic transmethod, deconstruction gave room to the revision of some works of this distinguished lawyer, philosopher, and educator, while the crisis was deconstructed. In reconstruction, the summons of Paulo Freire is fully urgent; freedom as a political issue for citizens, where education is rethought with dialogue and political literacy. The political commitment to liberation is resumed considering the liberation from the crisis of life, especially in Venezuela.

Published: March 2021

Beras merupakan makanan pokok yang paling banyak dikonsumsi oleh masyarakat Indonesia yang dihasilkan dari penggilingan gabah kering. Pada proses penggilingan gabah kering terdapat beras yang berbeda bentuk yaitu beras utuh dan tidak utuh. Hal itu disebabkan oleh kualitas padi yang kurang bagus. Dari perbedaan bentuk beras memiliki nilai jual yang lebih tinggi. Beras yang utuh akan lebih mahal dibandingkan beras yang tidak utuh. Oleh karena itu dilakukan penyortiran untuk mendapatkan perbedaan beras. Penelitian ini membuat suatu alat penyotir beras dengan sistem berupa mekanisme engkol peluncur sebagai sistem getaran. Alat ini mempunyai beberapa komponen yang terdiri dari dua mesh dan dua buah turnbuckle eye & eye sebagai pengaturan kemiringan ayakan. Dalam eksperimen kemiringan didapat dua variasi sudut yaitu sudut 10° dan sudut 15°. Pada alat ini menggunakan motor listrik satu phase sebagai penggerak poros engkol peluncur. Sistem transmisi menggunakan pulley dan v-belt yang dari motor listrik satu phase yang diteruskan ke pulley. Dari hasil pengujian yang telah dilakukan variasi dua sudut dengan kapasitas 10 kg. Pada sudut 15° didapatkan beras murni 69% dengan hasil kurang maksimal karena kemiringan sudut terlalu curam. Sedangkan pada sudut 10° didapatkan hasil beras murni 85% yang mempunyai kemiringan sudut lebih minim sehingga penyortiran beras lebih maksimal.

One alternative for environmentally friendly vehicles is wind-powered bikes. This vehicle can reduce air pollution and can be convenient in big cities. The proposed bike is equipped with a distance sensor to sense the safe proximity to nearby obstacles. If the obstacles are below a reasonable distance, the mounted buzzer is active as the warning. This bike uses the wind generated by the 8045 hp dc rotation. The pulse-width (PWM) modulation is used to control a dc engine rotational speed with a fixed value of 155 = low and 255 = high. Fuzzy Logic Controller is used to increasing system effectivity to processes the input from the proximity sensor. The sufficient distance between the bike and the obstacles ahead, right and left, is set to be 1 meter. The PID controller ensures that the dc motor rotations are smooth and steady to ensure that the PWM value is still positive. In order to maintain a stable state Kp = 60, Ki = 4.2, and Kd = 2.9 are set as the appropriate settings for the used PID constants.

Technological developments continue to develop rapidly until the generation of the Internet of things (IoT). IoT is a collection of objects, in the form of physical devices (hardware / embedded systems) that can exchange information between operators or other devices connected to the system. One of the benefits that can be felt is a smart home or smart home, which is a term used to describe a modern residence, with remote control such as controlling electronic goods. This control is intended for savings in electricity use. By using the ESP32 which functions as a liaison between the device and the internet network so that electronic goods that are available from home can be controlled by using an application installed on the smartphone. Based on tests carried out for the same network with a distance of 20 meters the device is successfully controlled, namely turning on and off the electronic device with a response time of 5s for the fastest time and 40s for the longest time, then for different networks, the control can still be done. So that with this smart home application, electricity costs can be saved.
Gendered Pathways to Science: The Perceived Impact of Social Ties and Individual Preferences
Authors: Danilo Estelle , Shi Youjia , Pflaumer Gabriela
Published: March 2021

Despite the huge effort taken to promote gender parity in Science Technology Engineering and Mathematics education, women remain overwhelmingly underrepresented in these fields. Current literature has demonstrated that there are significant processes that influence whether or not someone pursues STEM; yet, none of them specify the perceived individual and environmental factors that correlate with persistence in STEM education. Ergo, the focus of this paper is to try to account for the individual and social causes of persistence in pursuing STEM studies, as perceived by women and men who chose and continued to study STEM at college; more specifically, the nature, timing, and relative influence of these perceived determinants and how they vary according to gender. We have not followed a traditional quantitative research protocol that reaches causal claims. Instead, we have used self-reported retrospective data that offer subjective insight into the perceived determining factors to enter the pathway to STEM at college. To do so, we have conducted a survey, situating STEM undergraduate students at Columbia University in a sequence of events, influences, interactions, and institutions that are successively associated with their current orientation towards STEM disciplines. This research design has enabled us to look at the relative perceived influence of their social ties and individual preferences at three different stages of their life. While men and women who chose to major in STEM do not seem to have fundamentally different perceived individual preferences, they do seem to perceive the contribution of their social environment to their interest in science differently.

Political condemnations of professor Salih Burek during 1970s
Authors:   Faculty of Economics, University of Tuzla, Hodžić Kadrija
Published: March 2021

Salih Burek is one of the most respected economists in B&H, a professor and economic thinker of the Tuzla region from the late 50s to the early 1970s. Due to critical approaches to the party leadership of the Tuzla basin and the development of the contradicted economic concepts of the development of the chemical industry in Tuzla, it is strongly politically discredited and removed from public life. Politically-designed police accusations are classified as so-called Tuzla group, which in the mid-1970s was at the center of the biggest political affair in the socialist times of Tuzla and Bosnia and Herzegovina as a whole. Burek was the closest associate of Pashaga Mandzic, the hero of the revolution and the most important political figure of Tuzla of that time, proclaimed the leader of the so-called Tuzla Group. In the structure of the assembled political and police-judicial incrimination of Pasaga Mandzic and Tuzla group consisted literally of all ideological and political hostilities that existed at the time against socialism and socialist self-government in Yugoslavia. The interweaving of the fate of Salih Burek and Pasaga Mandzic and the common political suffering will make their biographies almost inseparable. By a judgment of the District Court in Tuzla (1975), he was sentenced to six years in prison in Zenica. After exiting from prison (1981), he again dedicated himself as a scientific associate of the Economic Institute in Tuzla to the improvement of the economic development of the Tuzla area.

Bordetella pertussis: An agent not to be forgotten in Qatar
Authors: Hasnain Samina , Mundodan Jesha , Al Bayat Soha , Khogali Hayat , Al-Romaihi Hamad
Published: March 2021

Background: Pertussis (whooping cough) is a vaccine-preventable disease caused by the bacterium Bordetella pertussis that is spread by airborne respiratory droplets. Clinical symptoms vary from infants to adults and are most contagious before the onset of symptoms. Infants are at the highest risk of infection, especially before they are old enough to receive at least two doses of pertussis-containing vaccine. There have been no indigenous cases of pertussis in Qatar since 2010 until 2018, due to free pertussis-containing vaccines under the National Immunization Schedule of Qatar, with coverage consistently above 95%. Two cases were reported in 2016 but were found to be imported. In 2019, 20 infants were reported as suspected pertussis to the Health Promotion and Communicable Disease Control (HP-CDC), Ministry of Public Health (MOPH), Qatar; of them, five were laboratory confirmed as pertussis.

Objective: This study aimed to describe the five confirmed cases of pertussis reported to HP-CDC, MOPH, Qatar, between January 1 and December 30, 2019.

Summary of Cases: All five confirmed pertussis cases were under one year old, and three were boys. All except one were immunized-for-age, and three had not received any doses of pertussis-containing vaccine and in none of the cases had the mother received tetanus, diphtheria, and acellular pertussis (Tdap) vaccine during pregnancy. All infants were born in Qatar, and two were Qatari nationals.

Conclusion: There may be a possibility of re-emergence of pertussis in Qatar. Active immunization and coverage maintenance are the best tools to prevent re-emergence. Undiagnosed and untreated pertussis cases are potential sources of infection. The partial or unimmunized groups may be significantly at risk, especially during infancy and before reaching the age to complete the three primary doses of diphtheria, tetanus, and pertussis vaccines. Focus on increasing awareness among those providing antenatal care, regarding the importance of Tdap vaccination during pregnancy, is necessary.
Incidencia de cáncer en la Región de Coquimbo, estimada según resultados de biopsias, años 2006 al 2015
Authors: Sarria-Cárcamo Haylyn , Ramírez-Santana Muriel
Published: March 2021

Introducción: A pesar de que los cánceres producen alta carga de enfermedad en Chile, se carece de un registro poblacional de cáncer nacional. El objetivo de estudio fue estimar la incidencia de los veinte principales tipos de cáncer en la Región de Coquimbo.

Material y métodos: Con datos del registro de la Unidad Anatomía Patológica del Hospital de Coquimbo, que procesa totalidad de las biopsias procedentes de los establecimientos públicos de la región; se estimó la incidencia de estas patologías. Se caracterizaron los cánceres según tipo, sexo y grupos de edad. Se calculó tasas de incidencia de los quinquenios 2006-2010 y 2011-2015, utilizando como denominador la población beneficiaria del Fondo Nacional de Salud. Finalmente se realizó una proyección lineal de la incidencia hasta el año 2025.

Resultados: Las mujeres presentaron una mayor tasa bruta de incidencia que los hombres. La incidencia aumenta, en ambos sexos, conforme aumenta la edad. Los cánceres más incidentes en mujeres fueron de mama, de piel no melanoma y de cuello uterino, y entre los hombres, fueron los cánceres de piel no melanoma, de próstata y gástrico.

Discusión: Dada la elevada frecuencia relativa de cánceres de tiroides, testículo, cuello de útero y mama en edades jóvenes, se sugiere orientar estrategias preventivas hacia estos grupos de edad. Así mismo, se debiera establecer programas integrales para los cánceres más frecuentes (piel no melanoma, próstata, colon). De no existir políticas públicas enfocadas a prevenir los cánceres, se proyecta un crecimiento lineal de hasta un 22% en la incidencia al año 2025.
Apoyando el desarrollo de la competencia mirar profesionalmente del futuro profesorado de matemáticas: Práctica e investigación
Authors: Fernández Ceneida
Published: March 2021

La competencia docente mirar profesionalmente es vista como una componente de la práctica profesional del profesor de matemáticas, y, por tanto, ha sido identificada como una competencia docente importante a desarrollar en los programas de formación de profesorado. El grupo GIDIMAT de la Universidad de Alicante (España) se ha centrado en investigar el desarrollo de esta competencia en futuro profesorado de educación infantil, primaria y secundaria. Para el desarrollo de esta competencia se diseñan entornos de aprendizaje específicos dentro de los programas de formación. En este artículo se presenta un ejemplo de entorno de aprendizaje y los principales resultados obtenidos del desarrollo de la competencia. El artículo se divide en cinco secciones. En la primera, se revisan estudios centrados en la competencia mirar profesionalmente el pensamiento matemático de los estudiantes y su relación con los dominios de conocimiento. En la segunda, se presenta una revisión de estudios centrados en su desarrollo. En la tercera sección, se presenta la metodología usada por el grupo GIDIMAT a través de ciclos de investigación en el diseño de entornos de aprendizaje. Además, se presentan las características de los entornos y viñetas usadas. En la cuarta sección se muestran resultados obtenidos relacionados con la caracterización de grados de desarrollo de la competencia docente. Finalmente, se discuten algunas implicaciones y trabajos futuros.
AS CRIANÇAS QUE CALCULAVAM: em situação de risco social e de exclusão de aprendizagem matemática
Authors: Muniz Cristiano Alberto
Published: March 2021

A busca pela compreensão da constituição do ser matemático como sujeito que aprende e produz sentidos subjetivos de sua capacidade em elaborar conhecimentos matemáticos encontra na categoria “sujeito que aprende”, da Teoria da Subjetividade-TS, um conceito que tanto amplia quanto aprofunda as análises interpretativas da constituição matemática de crianças. A TS possibilita ampliação da compreensão do fenômeno da aprendizagem matemática para além da análise estritamente cognitiva, de análise microgenética das produções de registros matemáticos, o que realizamos nas últimas décadas apoiados na Teoria dos Campos Conceituais. Apoiados em diálogos produzidos em oficinas matemáticas lúdicas e na conversação com mães sobre suas histórias educativas, buscamos sentidos subjetivos na história de aprendizagem matemática de quatro crianças em situação de risco. Além do diálogo estabelecido ao longo das oficinas lúdicas, coletamos suas produções matemáticas. Esses registros, somados aos constantes diálogos em contexto, permitiram a análise e a explicitação de esquemas matemáticos implícitos nessas produções matemáticas e revelaram importantes elementos constituidores dos complexos processos de aprendizagem matemática. Entretanto, as análises microgenéticas não foram suficientes para o desvelamento da complexa dimensão simbólicoemocional de significação de aprendizagens matemáticas pelos sujeitos. O diálogo com as crianças e suas respectivas mães, por meio de conversão videogravada, permitiu melhor compreender a natureza das produções e seus significados para além da situação da atividade lúdica. Este artigo se limita a trazer a análise de apenas um desses casos investigados, de um menino com deficiência auditiva e que, portanto, apresenta dificuldade na organização dos algoritmos matemáticos.
Social pediatrics in a baccalaureate nursing curriculum
Authors: Dhari Ranjit , MacPhee Maura , Pixton Matthew
Published: March 2021

This paper describes the use of social pediatrics in one baccalaureate nursing curriculum. Social pediatrics is a conceptual model that considers health as physical health and the social determinants of health. Social pediatrics focuses on community-based primary healthcare services for at-risk children and their families. The social pediatrics model is used by community early childhood education StrongStart sites in one Canadian province; these sites are collaborations between early childhood educators and public health nursing teams for children from infancy through five years of age. Acute care clinical placements are becoming too complex and limited in number to accommodate large undergraduate nursing cohorts. Our undergraduate nursing program recently shifted acute care pediatric placements to StrongStart sites, combining community pediatric and public health nursing learning objectives and learning activities that foreground social pediatrics. The acute care component of pediatric nursing includes classroom theory, clinical laboratory and virtual simulations. This paper describes social pediatrics integration within our undergraduate curriculum between 2018-2019; and a qualitative evaluation of our social pediatrics approach in 2019-2020. We used content analysis to identify common themes from interviews with key actors, including students’ clinical instructors, StrongStart sites’ early childhood educators and managers, and public health nurse managers affiliated with StrongStart sites. Common themes were related to social pediatrics learning opportunities and drawbacks; social pediatrics knowledge, skills and attitudes; and recommendations for curriculum enhancement.
Na trama discursiva de antologias de ensaios sobre o Brasil: constituição, formulação circulação de sentidos
Authors: Dias Luciana Cristina Ferreira
Published: March 2021

Considerando a problemática acerca da identidade nacional nos estudos de perspectiva discursiva (PÊCHEUX, 1988; ORLANDI, 1999), este trabalho busca refletir sobre duas coleções de ensaios: Nenhum Brasil existe e Intérpretes do Brasil, estabelecendo conexões entre os três processos de produção da linguagem na antologia: sua constituição (memória discursiva, interdiscurso), formulação (textualização da antologia) e seus modos de circulação na sociedade. Neste caso, examinamos a relação entre a materialidade lingüística e discursiva no domínio da formulação e circulação quando estávamos confrontados com a organização dessas coleções, considerando as implicações das antologias entendidas enquanto gênero do discurso.

Por uma pedagogia do oral
Authors: Magalhães Tânia Guedes
Published: March 2021

Este artigo traz contribuições sobre o trabalho com a oralidade na escola. Nas últimas décadas, vários foram os autores que contribuíram para o tema em questão, orientando que, embora a escrita seja central, a oralidade letrada também precisa ser enfocada na escola. Assim, apresentamos pressupostos teóricos fundamentais ao trabalho com a modalidade falada, bem como elencamos argumentos para uma pedagogia que contemple a oralidade. Além disso, listamos alguns conceitos basilares ao trabalho escolar com a fala, tais como oralidade, modalidade falada, oralização da escrita e atividades prosódicas. As bases teóricas deste trabalho estão, principalmente, em Marcuschi (1996, 2001) e Schneuwly e Dolz (2004) e nos PCN (1998).
O ensino de língua portuguesa no Estado do Paraná: uma abordagem sobre a concepção de linguagem do século XIX e a concepção priorizada atualmente pelos PCNs
Authors: Simm Juliana Fogaça Sanches , Almeida Baronas Joyce Elaine de
Published: March 2021

Neste trabalho objetivamos apresentar um breve perfil do ensino de Língua Portuguesa no século XIX, estabelecendo um paralelo com os ( PCNs) vigentes. Buscamos analisar a concepção do ensino de Língua Portuguesa no Estado do Paraná e verificar as mudanças que ocorreram no ensino até então. Primeiramente iremos abordar a maneira como era tratada a disciplina no Brasil, para em seguida falarmos especificamente sobre o Paraná. Podemos constatar, ao final desta pesquisa, que o conteúdo trabalhado no século XIX focalizava-se exclusivamente no ensino de aspectos gramaticais, ao contrário do que prevê os PCNs atuais, que priorizam o texto como objeto de ensino.
A motivação de topônimos indígenas de Mato Grosso do Sul
Authors: Tavares Marilze
Published: March 2021

Neste estudo, procedemos a uma análise dos topônimos indígenas de Mato Grosso do Sul, verificando quantos e quais são os elementos que motivam o denominador no ato da escolha dos nomes indígenas para os acidentes geográficos. Os dados que constituem o corpus deste trabalho foram coletados, essencialmente, de cartas do IBGE (1987) da escala de 1:250:000. O exame dos nomes geográficos evidenciou que elementos da natureza, tais como as plantas, os animais, a água e as características do solo, são as principais fontes de motivação no processo de nomeação – quando utilizados nomes de origem indígena – dos acidentes físicos e humanos.
Um estudo sobre o tempo em Narradores de Javé
Authors: Alves Carolina Assunção e
Published: March 2021

Muitas versões da história de um vilarejo são reveladas nos “causos” dos Narradores de Javé, do filme de Eliane Caffé (2004). A obra se desenvolve por meio de uma rede de narrativas que aparece como forte marca discursiva. Metz (2004), teórico da semiologia do cinema, afirma que a narrativa é primordialmente um sistema de transformações temporais. O objetivo deste trabalho é discutir como se configura a construção das narrativas e, conseqüentemente, das diversas temporalidades instauradas nessa peça cinematográfica. Para tanto, será buscado apoio nas reflexões sobre tempo e narrativa de Benveniste (1989), Metz (2004), Nunes (1988) e Ricoeur (1995).
Os róticos no sul do Brasil: panorama e generalizações
Authors: Brescancini Claudia , Monaretto Valéria Neto de Oliveira
Published: March 2021

As pesquisas realizadas com dados de fala do Projeto VARSUL indicam que a variável vibrante está condicionada principalmente pelo grupo geográfico e pela posição que ocupa na sílaba. O que se observa, em todas as pesquisas, é a presença de variantes anteriores (vibrantes e fricativas), tanto em posição de ataque como em coda. Este trabalho propõe esboçar resultados dessas pesquisas e examinar a possibilidade de comparação e generalização de tais resultados. Questões metodológicas, tendo por base o modelo de Labov (1994), serão reexaminadas na tentativa de se extrair regularidades e tendências.
A Conceptual and Operational Review of the Negative Financial Health Terminology and Constructs
Authors: Wuth Amanda , Cismaru Magdalena
Published: March 2021

Financial (di)stress is widespread and an important topic for research by a variety of organizations and disciplines. However, different terms are being used in different disciplines in academia, by organizations, and by consumers. This paper illustrates various terms used to describe negative financial health, provides their incidence in several academic databases and Google searches, provides definitions used in studies, identifies scales of measurement, assesses if new scales are being developed and if they have validity, and identifies if measures of negative financial health constructs include objective, subjective, or both measures. The study ends with specific recommendations for researchers from academia and practitioners worldwide. This article reviews financial negative health terminology and constructs, and attempts to shed light on similarities and differences among the terms, to allow for better knowledge translation and integration.
Drug-induced diseases in otolaryngology – causes, clinical signs, treatment

Published: March 2021

In the daily practice of an otolaryngologist, we encounter cases where the symptoms are not the result of disease but result from pharmacotherapy. In the case of symptoms such as hearing loss, tinnitus, or dizziness, polytherapy may be used as the basis for their occurrence, which, due to the lack of rationality in combining drugs, leads to symptoms that the patient and the doctor very often interpret as a new disease syndrome.

The aim of the study is to show and to raise awareness of the fact that the symptoms of hearing organ impairment are frequently drug-related and only a modification of the currently used pharmacotherapy is a rational procedure in such cases.

This paper describes 30 cases who developed side effects of polypharmacy in the form of hearing disorders, dizziness, and tinnitus. The causes of drug-related complications were discussed, as well as effective methods of their prevention.
