A data-driven approach to assessing the impact of water harvesting structures on regional water storage in East Africa
Authors: Eisma J. A. , Merwade V.
Published: January 2021

A small-scale water harvesting structure known as a sand dam has gained popularity across East Africa due to the efforts of non-governmental organizations. A sand dam is a subsurface water reservoir that stores water between sand grains. Stored thus, the water is filtered and protected from evaporation. This study uses remotely sensed data to investigate the impact of these structures on water storage and vegetative growth. The relationship between sand dams and water storage was modeled using a binary sand dam factor, climate data from the Famine Early Warning Systems Network Land Data Assimilation System (FLDAS), and water storage data measured by the Gravity Recovery and Climate Experiment (GRACE) twin satellites. The analysis revealed that GRACE largely fails to detect a statistically significant impact of sand dams on regional water storage. However, analysis of the Normalized Difference Vegetation Index (NDVI) indicated that sand dams have a significant impact on regional vegetation. Vegetative growth is correlated with groundwater levels, indicating that sand dams have a positive impact on water storage albeit on a smaller scale than GRACE can regularly detect. Significantly, this study shows that NDVI data can be used effectively to study small-scale, regional changes in vegetation and water storage.

Published: January 2021

Dredged sediment can occupy a large amount of land area, resulting in waste of land resources, and high disposal costs. In response to the problem, this work calcinates and modified the sediment and compounds it with the modified water purification plant sludge, zeolite powder, and bentonite. This is used as a covering material to inhibit the release of nitrogen (N) and phosphorus (P) in the sediment. The results showed that sediment modified composite material covering effectively reduces the release of nitrogen (N) and phosphorus (P) in the sediment, especially the release of P. When the thickness of the covering layer is 3 cm, the reduction rate of total N, NH4+-N, and total P in the overlying water by the modified composite material of sediment is 61.58, 79.59, and 70.34%, respectively. It can be seen that the covering material has a significant effect on the control of the release of N and P in the sediment. Additionally, the reduction of nutrients in the overlying water can overcome the negative effects of temperature rise in controlling the release of N and P in the sediment.

Published: January 2021

The solution mixture of the non-steroidal anti-inflammatory drugs ketoprofen, meloxicam and tenoxicam was degraded through systems, composed of different photocatalysts based on TiO2 (Fe and Cu) and the hydrogen peroxide oxidant. The monitoring was performed by UV-Vis spectroscopy. Under sunlight radiation, a reduction in peaks was observed with the use of impregnated photocatalysts. After 60 min, the sun/H2O2/Fe-TiO2 system reached degradations of 46.5% and 93.2% at 260 and 367 nm, respectively, and was selected for further studies. The degradation kinetic reached 92 and 96% of degradation after 180 min, for the λ of 260 and 367 nm, respectively. The kinetic curve could be represented by the empirical model proposed by Nichela and co-authors, indicating that besides the heterogeneous photocatalysis that occurs at the surface of the TiO2 there is also the joint effect of the photo-Fenton process. After the treatment, there was no toxicity to cress and lettuce seeds. However, a sensitivity of the thyme seeds to the compounds formed during the treatment was verified. After the fifth treatment cycle, the supported photocatalyst showed degradation higher than 82%. These results indicate that this system is suitable for the treatment of effluents containing pharmaceutical compounds.
Dosed Exposure to Low Temperature as a Breeding Background in The Selection of Gene Pool Breeds of Chickens for Viral Vaccines Production
Authors: Stanishevskaya Olga I. , Fedorova Elena S.
Published: January 2021

Background:

One of the ways to utilize the potential of local breeds is to use them as producers of raw materials for the bio-industry (production of vaccines and diagnostics for animals and humans).

Methods:

Breeding of Russian White (PRWC) laying hens in 5 generations was carried out with the aim of increasing the output of allantois-amniotic fluid of embryos with a selective background (cooling of hatching eggs during the sensitive period of embryogenesis). In F5, the thermoregulation capabilities of 7-day-old PRWC chickens were studied in comparison with Amrox chickens under the influence of a daily stress factor (cooling at +10oC for 30 minutes) and raising at +22oC. The level of allantois-amniotic fluid output and biological activity of the Newcastle disease virus in F5 PRWC embryos in comparison with F0 and commercial line embryos was evaluated.

Results:

Day-old PRWC chicks responded to exposure to low sublethal temperature with muscle shivering, but, unlike Amrox chickens, they were active and retained the reflex of searching for food. PRWC chickens raised at low temperatures up to 7 days of age maintained the same growth rate as chickens raised at a common regime but used less residual yolk, which practically did not decrease the body temperature, and change the level of thyrotrophic hormone in response to the dosed exposure at low temperatures at 7 days of age. The content of doses of the Newcastle disease virus (EID50) in the extraembryonic fluid of F5-embryos of PRWC was 32.3 times higher than that of commercial line ones.

Conclusion:

PRWC chicks in the early neonatal period are more reactive at low temperature and have better thermoregulation mechanisms. PRWC embryos can be recommended for use in the production of various viral vaccines as well as diagnosticums.

Published: January 2021

Tinnitus is a hearing disorder that causes ringing, buzzing or hissing sensation to the patient’s auditory senses. It has become a very common complaint over the years affecting around 7-8% of the human population all over the world. The disorder causes the patients to feel irritable, annoyed, depressed, and distressed. As a result, it obstructs their sense of relaxation, enjoyment, and even their sleep - thus forcing them to avoid any social gatherings. There has been a substantial amount of work that has been carried out pertinent to this disorder. This paper reviews existing research and work done regarding Tinnitus effects, causes, and diagnosis. The numerous ways in which Tinnitus could affect an individual have been depicted. From the plethora of probable causes of this disorder, the most conceivable ones are highlighted. Moreover, this paper documents and reviews the attempts at treating Tinnitus, relevant engineering breakthroughs, and the various ways in which Tinnitus noise is suppressed – such as Tinnitus Retraining Therapy, Neuromodulation, and Signal processing approach. The manuscripts highlight the pros and cons of these methods. Over 45 research articles and other reliable internet medical sources were reviewed and these pieces of work were contrasted. These findings should help in understanding both – the disorder, as well as the situation of the patients suffering from it. Through this manuscript, an attempt was made to spread awareness about the mysterious disorder.

Published: January 2021

The use of religious terms such as 'kafir' is seen as a form of radicalism because it discriminates against other groups; both Muslim and non-Muslim groups. Radicalism can encourage intolerant behavior and violence. In political contexts such as elections, mass groups often use these calls to discriminate against other groups that are considered to have different views. This study was conducted to find out how "kafir" are used and how participatory communication as a means of resistance. This study was conducted using a survey method for Muslim and non-Muslim students in Malang City. This study states, the context of "kafir" occurs in different ways. In social relations, kafir is used in a joke. But t is also considered tend to discrimination, especially when associated with conservative organizations and fundamentalist movements. When "kafir" are used discriminatively, respondents have the awareness to reject using the term. Forms of participatory communication are done through informal discussion forums rather than formal spaces.

Estudo Teórico in silico da Interação entre Geraniol e o Sítio Ativo da Opsina Bovina
Authors: Miranda Vanessa Regina , Morgon Nelson Henrique
Published: January 2021

The bovine opsin protein, 6PGS, is present in the eye of the Bos taurus species, and has activity throughout the period of development of the retina, remaining until its adult stage. The interaction of the geraniol ligand, which has anti-inflammatory, antimicrobial and antioxidant activities, with the active site of the protein was studied through theoretical calculations using Density Functional Theory. The molecular structure results show that in the interaction process of geraniol with the active site of 6PGS there is a distortion in the geometry of the ligand. Through the UV-Vis spectra, a shift of the wavelength maximum value in relation to the free geraniol is observed, of the order of 50 nm.

Factors Affecting the Implementation, Use, and Adoption of Real-Time Location System Technology for Persons Living With Cognitive Disabilities in Long-term Care Homes: Systematic Review
Authors: Grigorovich Alisa , Kulandaivelu Yalinie , Newman Kristine , Bianchi Andria , Khan Shehroz S , Iaboni Andrea , McMurray Josephine
Published: January 2021

Background

As the aging population continues to grow, the number of adults living with dementia or other cognitive disabilities in residential long-term care homes is expected to increase. Technologies such as real-time locating systems (RTLS) are being investigated for their potential to improve the health and safety of residents and the quality of care and efficiency of long-term care facilities.

Objective

The aim of this study is to identify factors that affect the implementation, adoption, and use of RTLS for use with persons living with dementia or other cognitive disabilities in long-term care homes.

Methods

We conducted a systematic review of the peer-reviewed English language literature indexed in MEDLINE, Embase, PsycINFO, and CINAHL from inception up to and including May 5, 2020. Search strategies included keywords and subject headings related to cognitive disability, residential long-term care settings, and RTLS. Study characteristics, methodologies, and data were extracted and analyzed using constant comparative techniques.

Results

A total of 12 publications were included in the review. Most studies were conducted in the Netherlands (7/12, 58%) and used a descriptive qualitative study design. We identified 3 themes from our analysis of the studies: barriers to implementation, enablers of implementation, and agency and context. Barriers to implementation included lack of motivation for engagement; technology ecosystem and infrastructure challenges; and myths, stories, and shared understanding. Enablers of implementation included understanding local workflows, policies, and technologies; usability and user-centered design; communication with providers; and establishing policies, frameworks, governance, and evaluation. Agency and context were examined from the perspective of residents, family members, care providers, and the long-term care organizations.

Conclusions

There is a striking lack of evidence to justify the use of RTLS to improve the lives of residents and care providers in long-term care settings. More research related to RTLS use with cognitively impaired residents is required; this research should include longitudinal evaluation of end-to-end implementations that are developed using scientific theory and rigorous analysis of the functionality, efficiency, and effectiveness of these systems. Future research is required on the ethics of monitoring residents using RTLS and its impact on the privacy of residents and health care workers.

Background

eCohort studies offer an efficient approach for data collection. However, eCohort studies are challenged by volunteer bias and low adherence. We designed an eCohort embedded in the Framingham Heart Study (eFHS) to address these challenges and to compare the digital data to traditional data collection.

Objective

The aim of this study was to evaluate adherence of the eFHS app-based surveys deployed at baseline (time of enrollment in the eCohort) and every 3 months up to 1 year, and to compare baseline digital surveys with surveys collected at the research center.

Methods

We defined adherence rates as the proportion of participants who completed at least one survey at a given 3-month period and computed adherence rates for each 3-month period. To evaluate agreement, we compared several baseline measures obtained in the eFHS app survey to those obtained at the in-person research center exam using the concordance correlation coefficient (CCC).

Results

Among the 1948 eFHS participants (mean age 53, SD 9 years; 57% women), we found high adherence to baseline surveys (89%) and a decrease in adherence over time (58% at 3 months, 52% at 6 months, 41% at 9 months, and 40% at 12 months). eFHS participants who returned surveys were more likely to be women (adjusted odds ratio [aOR] 1.58, 95% CI 1.18-2.11) and less likely to be smokers (aOR 0.53, 95% CI 0.32-0.90). Compared to in-person exam data, we observed moderate agreement for baseline app-based surveys of the Physical Activity Index (mean difference 2.27, CCC=0.56), and high agreement for average drinks per week (mean difference 0.54, CCC=0.82) and depressive symptoms scores (mean difference 0.03, CCC=0.77).

Conclusions

We observed that eFHS participants had a high survey return at baseline and each 3-month survey period over the 12 months of follow up. We observed moderate to high agreement between digital and research center measures for several types of surveys, including physical activity, depressive symptoms, and alcohol use. Thus, this digital data collection mechanism is a promising tool to collect data related to cardiovascular disease and its risk factors.

Published: January 2021

BACKGROUND

Due to the complexity and chronicity of heart failure, engaging yet simple patient self-management tools are needed.

OBJECTIVE

This study aimed to assess the feasibility and patient engagement with a smartphone app designed for heart failure.

METHODS

Patients with heart failure were randomized to intervention (smartphone with the Habits Heart App installed and Bluetooth-linked scale) or control (paper education material) groups. All intervention group patients were interviewed and monitored closely for app feasibility while receiving standard of care heart failure management by cardiologists. The Atlanta Heart Failure Knowledge Test, a quality of life survey (Kansas City Cardiomyopathy Questionnaire), and weight were assessed at baseline and final visits.

RESULTS

Patients (N=28 patients; intervention: n=15; control: n=13) with heart failure (with reduced ejection fraction: 15/28, 54%; male: 20/28, 71%, female: 8/28, 29%; median age 63 years) were enrolled, and 82% of patients (N=23; intervention: 12/15, 80%; control: 11/13, 85%) completed both baseline and final visits (median follow up 60 days). In the intervention group, 2 out of the 12 patients who completed the study did not use the app after study onboarding due to illnesses and hospitalizations. Of the remaining 10 patients who used the app, 5 patients logged ≥1 interaction with the app per day on average, and 2 patients logged an interaction with the app every other day on average. The intervention group averaged 403 screen views (per patient) in 56 distinct sessions, 5-minute session durations, and 22 weight entries per patient. There was a direct correlation between duration of app use and improvement in heart failure knowledge (Atlanta Heart Failure Knowledge Test score; ρ=0.59, P=.04) and quality of life (Kansas City Cardiomyopathy Questionnaire score; ρ=0.63, P=.03). The correlation between app use and weight change was ρ=–0.40 (P=.19). Only 1 out of 11 patients in the control group retained education material by the follow-up visit.

CONCLUSIONS

The Habits Heart App with a Bluetooth-linked scale is a feasible way to engage patients in heart failure management, and barriers to app engagement were identified. A larger multicenter study may be warranted to evaluate the effectiveness of the app.

Indonesia ranks 23rd as the most COVID-19 confirmed cases in the world. DKI Jakarta and East Java provinces have the highest cases in Indonesia. However, data on the transmission of COVID-19 in both provinces were not further analyzed regarding vulnerability between genders. This research attempted to compare the differences in the gender distribution of COVID-19 cases by analyzing data from COVID-19 DKI Jakarta and East Java Task Force Information Center and various biological, medical, and socio-cultural studies to understand risk of women being exposed to COVID-19. The results of this research revealed that both provinces had a higher number of confirmed patients under surveillance (PDP), people under surveillance (ODP), and death cases in men than that of women. In DKI Jakarta, the number of recovered cases in men was higher than that of women, but in East Java it was not significantly different. Based on literature reviews, women were more resilience in manifestations of COVID-19 severity than that of men due to differences in ACE2 gene distribution and expression, hormones regulations, immune responses, comorbidities, and ages. However, data from socio-cultural literature reviews in both provinces showed women were vulnerable to be exposed to COVID-19 since many women performed as health workers, office workers, market traders, public transportation users, and did religious activities. Besides, women were vulnerable due to mental health condition, such as depression, anxiety, and special medical condition (e.g. being exposed to or infected with COVID-19 during pregnancy).
Effect of coworker ostracism on newcomer socialization: A self-control perspective
Authors: Liu Pan , Zhang Yihua , Zhang Mingyu , Wu Wen
Published: January 2021

Researchers have consistently reported the negative role of workplace ostracism, and the importance of newcomers to an organization. However, none have examined the effect of coworker ostracism on newcomer socialization. Drawing on the strength model of self-control, we empirically
tested the effect of coworker ostracism on newcomer socialization via the mediator of state self-control. Participants were 155 matched supervisor–subordinate dyads. Results show that coworker ostracism toward newcomers was negatively related to newcomer socialization and that this relationship
was mediated by state self-control. Further, the direct effect of coworker ostracism on state self-control and the indirect effect of coworker ostracism on newcomer socialization were moderated by proactive personality. Theoretical and practical implications are discussed.
Knowledge sharing mediates the relationship between Zhongyong thinking and employee creativity
Authors: Fan Zhonghe
Published: January 2021

Zhongyong thinking is the Confucian doctrine of the mean; zhong means equilibrium and yong means harmoniousness, so that Zhongyong thinking represents maintaining balance and harmony. I examined the mediating effect of knowledge sharing in the relationship between Zhongyong
thinking and employee creativity in a Chinese context. I collected 285 paired surveys from part-time Master of Business Administration students who self-rated their Zhongyong thinking and knowledge sharing in their workplace, and their supervisors who rated their creativity. Results of structural
equation modeling analysis reveal that Zhongyong thinking had a positive indirect relationship with employee creativity through the mediator of knowledge sharing. These findings shed light on the ways in which Zhongyong thinking helps to enhance employee creativity. Managers of organizations
should pay attention to improving employees' Zhongyong thinking and facilitating employees' knowledge sharing. Study limitations and suggestions for future research directions are discussed.

Published: January 2021

We examined the factorial validity, measurement invariance, reliability, and concurrent validity across gender groups of the simplified Parenting Stress Index-Short Form (S-PSI-SF) with a group of 486 Chinese parents of children with cerebral palsy. Participants completed the S-PSI-SF
and the Multidimensional Scale of Perceived Support. Findings based on a confirmatory factor analysis suggest that the original three-factor model was duplicated in this population, and displayed measurement invariance for both fathers and mothers. The internal reliability of the S-PSI-SF
was confirmed, and composite reliability values were larger than .70. Furthermore, all subscales of the S-PSI-SF were significantly correlated with the Multidimensional Scale of Perceived Support. These results show that the S-PSI-SF is a trustworthy and effective tool for evaluating parenting
stress and can be used confidently with both fathers and mothers of children with cerebral palsy.

Authors:   Ulyana E. Kochetkova St Petersburg State University, Kochetkova Ulyana E.
Published: January 2021

This study analyses occurrence of the uvular and alveolar /r/ in French sung speech; its material includes Art Songs written by French composers of the late 19th - early 20th century. At the first stage of this study the uvular consonant occurrence in different age groups of singers is compared, the main /r/_articulation model is considered for every singer. Then deviations from the alveolar articulation model, i. e. changes to the uvular /r/, are analyzed in various phonetic environment. The current study's results enable to conclude that (i) most of the alveolar [r] are maintained after the breath pause and before the semivowels, (ii) the uvular articulation exists in the Art Songs interpretation by French operatic singers representing different age groups.

Despite a considerable number of Russian and foreign works researching discourse markers, there is still no common opinion about the boundaries of this group of words, neither there are principles and criteria for their classification. We identify and summarize possible functions of discourse markers in different types of discourse. It was discovered that being the units of functional-pragmatic level, they provide text cohesion. Discourse markers are represented by various grammatical word classes, are used mostly in preposition and are characterized by dynamic nature.

In the 21st century, migration processes become particularly important. Changes in politics and economy, natural resource and environmental problems determine widespread movements and migrations of people, more often from East to West, which in its turn causes significant changes in languages and cultures. This article considers the process of semantic potential expansion of the French verb aimer as a result of differentiation and unification tendencies. The expansion is connected with borrowings from English and Arabic into the French culture.

Authors: Campos Marcelo Bergamini
Published: January 2021

O livro Educação Matemática no contexto da Economia Solidária apresenta um estudo envolvendo o processo de ensino e aprendizagem de Matemática articulado ao desenvolvimento de intervenções pedagógicas realizadas junto aos membros de três Empreendimentos Econômicos Solidários. O Programa Etnomatemática e a Resolução de Problemas são tomados como referenciais teóricos e eixos norteadores diante da perspectiva de discutir a Matemática de forma significativa e contextualizada. A investigação se caracteriza por uma abordagem qualitativa e adota por base a pesquisa-ação com o propósito de contribuir para que os envolvidos assumam uma postura emancipadora no ambiente em quem estão inseridos.
“Indisciplina” en Chocó: una problematización de las prácticas disciplinarias en tiempos de pandemia
Authors: Charry Gutiérrez Oscar Guillermo , Tamayo-Osorio Carolina , Jaramillo Diana
Published: January 2021

Partiendo del enunciado, “nos preocupa muchísimo el alto grado de indisciplina social (…) cuando tenemos una epidemia tan grave con la COVID-19”, en este artículo se propone realizar una problematización indisciplinar de las prácticas disciplinarias presentes en las medidas para la contención de la pandemia. Para ello, se asume una actitud terapéutico deconstruccionista, inspirada en los filósofos Wittgenstein y Derrida; a través de la cual no se busca defender o refutar ese enunciado, sino verlo de otras maneras, desplazando las prácticas disciplinarias por distintas épocas, contextos y campos de actividad humana. Para posibilitar este desplazamiento, se establecen algunas articulaciones, principalmente, con la obra de Foucault “Vigilar y Castigar”, en relación con el modelo disciplinar y el examen en tiempos de la peste del siglo XVIII y en la actualidad. Finalmente, se presentan las nociones de escuela, currículo y evaluación a partir de las prácticas sociales de algunas comunidades indígenas del departamento del Chocó; nociones que estarían emparentadas con las que expone Miguel, Vilela y de Moura (2010; 2012) y Miguel (2016;2018) en una perspectiva indisciplinar.
A cultura Chokwe da Lunda Norte (Angola) e o Programa Etnomatemática: diálogos para repensar a educação em tempos de pandemia
Authors: Coppe de Oliveira Cristiane , Mucuta Santos Carlos
Published: January 2021

Este artigo, de cunho investigativo e reflexivo, nasceu a partir de diálogos entre os autores nas sessões de orientação do Programa de Mestrado em Ciências da Educação da Universidade Lueji A’Nkonde, em parceria com a Faculdade de Educação da Universidade de São Paulo (FEUSP).Os diálogos privilegiaram, tanto as teorizações do educador Ubiratan D´Ambrosio acerca do papel da educação a partir das dimensões do Programa Etnomatemática no sentido de encaminhar a investigação em vertentes teórico-metodológicas, quanto a visão antropológica da cultura Chokwe da comuna de Camaxilo (Lunda Norte/Angola), especificamente acerca da ação comunitária da aprender no chota cha makulwana[1]. O diálogo ao longo da investigação foi tecendo uma proposta metodológica apoiada nesta ação, contribuindo para novas reflexões e epistemologias que podem emergir ao se pensar no papel social/cultural da escola e da educação nos períodos antes, durante e após a pandemia da COVID-19. Diante do exposto, este artigo pretende compartilhar os diálogos entre orientadora e orientando Chokwe, ao longo do desenvolvimento de uma investigação de mestrado, buscando caminhos nessa cultura para repensar a escola e seu papel na sociedade. O estudo mostrou que os valores culturais encontrados no chota cha makulwana podem ampliar o sentido na escola e seu papel na sociedade para além da constituição de saberes de orientação eurocêntrica.

[1] Chota cha maulwana é considerado como  jango (casa) dos anciãos do povo, o epicentro de toda aldeia chokwe, um símbolo da autoridade, da integridade e da unidade dos membros de uma comunidade chokwe.
Desterritorializando a escola como a gente a conhecia: perspectivas socioculturais da Educação Matemática no contexto da Pandemia
Authors: Tamayo Osorio Carolina , do Valle Julio
Published: January 2021

Este volume especial é um espaço que reúne reflexões de pesquisadores convidados para problematizar e desestabilizar esse território chamado ‘escola’ ou ‘classe de Matemática’ que, pautado pelo desejo de manter em funcionamento os dispositivos disciplinares que organizam a aprendizagem e ensino, tem gerado novas demandas para todos os sujeitos vinculados de uma outra forma à educação.
Comparación de hallazgos matemáticos en grupos culturales diferenciados mediante el modelo metodológico MOC - ETNO
Authors: Uribe Suarez David Enrique , Acevedo Caicedo. Myriam , Rojas Velazquez Osvaldo , Yojcom Rocché Domingo
Published: January 2021

Este artículo presenta el modelo metodológico comparativo con enfoque etnomatemático (MOC-ETNO), compuesto de cuatros fases: descripción, interpretación, comparación y acciones, para identificar y contrastar las prácticas ancestrales de las culturas Wayuu y Arhuaca respecto al saber y al hacer con patrones de medida. Este estudio es parte de una investigación doctoral, cuyo objetivo fue diseñar un modelo, sustentado y fundamentado teóricamente en cada una de las dimensiones del programa de etnomatemática, con un principal interés en las actividades matemáticas universales propuestas por Bishop y en el uso del método comparativo. La metodología de investigación se ubica en el paradigma de investigación cualitativo – hermenéutico, con un enfoque relativista y de tipo etnográfico.
Etnogeometría aymara: propuesta de terminología matemática para la escuela rural de Perú
Authors: VILCA APAZA HENRY MARK , Sosa Gutierrez Fredy
Published: January 2021

El presente estudio es una aproximación a la etnogeometría aymara que tiene por objetivo la identificación de terminología matemática sobre geometría aymara, bajo el soporte epistemológico de la Etnomatemática y la interculturalidad, esperando que pueda tener una repercusión positiva en el aprendizaje y la identidad de los estudiantes de las escuelas rurales de Puno, donde existe problemas a causa de la interferencia lingüística. En el marco del método etnográfico, la información se obtuvo mediante visitas y entrevistas a los aymarahablantes de las comunidades de la provincia de Moho y El Collao de la región Puno - Perú, contrastada y complementada con fuente documental Vocabulario de la lengua aymara de 1612 y literatura especializada actual (libros y diccionarios). Los términos geométricos se identificaron por equivalencia y aproximación conceptual, y este proceso demostró que la lengua aymara cuenta con un rico bagaje léxico matemático propio y flexible para adaptarse a las exigencias científicas y pedagógicas actuales sea por creación de neologismos o préstamos de lenguas primas o extranjeras, en caso de vacíos. La terminología presentada en tablas fue escrita respetando las normas lingüísticas del aymara, y se espera sea estandarizada y socializada por las autoridades del Ministerio de Educación, y sirva de base a futuras discusiones e investigaciones.
Classificação dos modos como a (etno)matemática se expressa nos provérbios populares portugueses
Authors: Costa Cecília
Published: January 2021

Os provérbios populares portugueses são de grande riqueza e encerram conhecimento e saber-fazer em múltiplas áreas da vivência popular que importa descobrir e preservar. Não temos conhecimento de estudos sobre a etnomatemática existente nos provérbios populares portugueses. Dada a riqueza destes e a potencialidade de utilização no ensino e na aprendizagem da matemática, propomo-nos apresentar aqui uma abordagem iniciadora ao assunto. De um núcleo de cerca de 2000 provérbios, num primeiro nível de análise procedemos à identificação dos conceitos matemáticos existentes. Num segundo nível de análise, procedemos à categorização do modo como a (etno)matemática surge nos provérbios populares portugueses. Estabelecemos três categorias: Modo 1 Explícito, Modo 2 Implícito e Modo 3 Subtil. Ilustramos cada categoria e explicamos a etnomatemática envolvida de modo a deixar claro a possível utilização dos provérbios em sala de aula de matemática de vários níveis de ensino.
Beyond songs and dances: Ethnomathematics and the challenge of culture
Authors: Vidal Alangui Wilfredo
Published: January 2021

In this paper, I discuss the pitfalls of the anthropological notion of culture when used in the field of ethnomathematics, and use Dowling’s myth of reference and myth of emancipation to show how these are linked to what I refer to as the dual dangers – the dangers of decontextualization and knowledge colonization in the field of ethnomathematics. I argue that these two dangers arise from a naïve approach to ethnomathematics research that is informed by the anthropological notion of culture. The paper provides some examples from the Philippines and one from New Zealand on how these dual dangers may manifest while pursuing studies in ethnomathematics and programs for culturally relevant mathematics education.
