Constructing a mathematical model and studying numerically the effect of bio-clogging on soil filtration consolidation
Authors: Ivanchuk Natalia , Martyniuk Petro , Michuta Olga , Malanchuk Yevhenii , Shlikhta Hanna
Published: May 2021

Mathematical modeling and computer simulation methods have been used to investigate the extent of influence exerted by bio-clogging on the dynamics of excess head scattering in the soil massif. To this end, the classical equation of filtration consolidation has been modified for the case of variable porosity resulting from changes in the biomass. The numerical solution to the constructed mathematical model in the form of a nonlinear boundary problem was derived by a finite-element method. Numerical experiments were carried out and their analysis was performed. Specifically, this paper shows the charts of pressure differences in the soil array when neglecting bio-clogging and when estimating the effects exerted by bio-clogging at specific points in time. The numerical experiments demonstrated that in two years after the onset of the consolidation process in the neighborhood of the lower limit of the examined soil mass with a thickness of 10 meters, excess heads fall from the initial value of 10 m to 4 m. The greatest impact from the clogging of pores by microorganisms is revealed in the neighborhood of an upper limit. At a depth of 1 m, at t=180 days, the pressure difference reaches 2.4 m. This is about 200 % of the pressure distribution without taking into account the effects of bio-clogging. Over time, the effect of bacteria on the distribution of pressures in the neighborhood of the upper boundary decreases. However, this effect extends to the entire soil mass, up to the lower limit. Thus, at t=540 days, at the lower limit, the effect of bio-clogging leads to that excess heads are 1.8 m greater than for the case of pure water filtration (a relative increase of about 80 %).
Bio-clogging processes are intensified as a result of the development of microorganisms when organic chemicals enter the porous environment. Therefore, from a practical point of view, studying them is especially relevant for household waste storage facilities and the stability of their soil bases. It is advisable to undertake research by using the methods of mathematical modeling and computer simulation
Devising a procedure to form the diagnostic parameters for locomotives using a principal components analysis
Authors: Bodnar Borys , Ochkasov Oleksandr
Published: May 2021

Modern diagnostic systems are characterized by that the flow of diagnostic information requires significant computational resources to process. In order to improve the reliability of the object to be diagnosed and reduce operating costs, it is necessary to improve procedures for analyzing diagnostic results. This paper suggests a procedure to form the diagnostic features of locomotive nodes based on the use of a principal components analysis. The proposed approach is distinguished by a decrease in the dimensionality of the input set of diagnostic features in order to select the sets of interconnected diagnostic parameters. Based on the selection of the sets of interconnected diagnostic features, constructing new latent diagnostic parameters has been proposed. A latent diagnostic parameter contains information that combines data from several initial diagnostic features. The result of the method is a set of latent diagnostic parameters that do not correlate with each other and reflect the behavior of the object to be diagnosed from different technical points. The application of a sufficient number of latent diagnostic parameters involved the scree test method. This paper reports the results from using the proposed approach for treating the results from diagnosing the hydraulic transmissions in locomotives. The result from applying the procedure has made it possible to propose using three latent diagnostic parameters to assess the technical condition of a locomotive’s hydraulic transmission during bench tests. The suggested parameters contain 90 % of the original information and reflect losses in the transmission, as well as the load at the input and output of the transmission.

Published: May 2021

The aim of the work was to study the monosaccharide composition of WSPS, PS and HC, isolated from the raw materials of Camelina sativa and Camelina microcarpa and to establish the quantitative content of these fractions.

Materials and methods. The analysis of the composition of biologically active substances of carbohydrate nature was carried out in herb and seeds of Camelina sativa (variety “Slavutych”) and Camelina microcarpa. Samples of seeds for growing plants were provided by the National Center for Genetic Resources of Plants of Ukraine (The Plant Production Institute ND. V.YA. YURIEVA, NAAS of Ukraine).

For the studies, the carbohydrates were separated by the Bailey method into monosaccharide fractions, which were used for TLC and quantification using a modified Dreywood spectrophotometric method with anthrone reagent in concentrated sulfuric acid.

Results. The presence of glucose, galactose and arabinose was determined in the hydrolysates of polysaccharide fractions of Camelina sativa of herb and seeds. Galactose, glucose, arabinose and xylose were found in the hydrolysates of polysaccharide fractions of Camelina microcarpa herb and seeds. The highest content of WSPS was determined in the herb of Camelina sativa, and the lowest - in the seeds of Camelina microcarpa. PS in the largest number were also found in the herb, and in the smallest – in the seeds of Camelina sativa. The content of the amount of HC was the highest in the herb of Camelina sativa, and the smallest – in the seeds of Camelina sativa.

Conclusions. The presence of 3 monosaccharides in the raw material of Camelina sativa and 4 monosaccharides in the raw material of Camelina microcarpa was established by TLC. The quantitative content of monosaccharide fractions was determined by the spectrophotometric method, which in total predominated in Camelina sativa

The aim: to investigate the effect of a new derivative of 4-aminobutanoic acid (compounds KGM-5) on the level of neurotransmitters and neurotransmitter amino acids and the structural-functional state of the hippocampus of rats with acute cerebrovascular accident (ACVA).

Materials and methods. ACVA was reproduced in rats by occlusion of the left carotid artery under anesthesia (sodium thiopental (35 mg/kg) intraperitoneally (i/p). 5 groups of animals were used: intact control (IC, n=6), untreated animals with ACVA (CP, n=13); animals with ACVA (n=14), which were treated for 5 days with KGM-5 at a dose of 30 mg/kg i/p, animals with ACVA (n=13), who received i/p comparison drug “Picamilon” (17 mg/kg). There was a group of pseudo-operated animals (POA, n=8). Withdrawal of animals from the experiment was performed on day 6 after modeling ACVA by painless euthanasia under anesthesia. Histological examinations of CA1 and CA3 zones of the ventral hippocampus were performed with staining of sections with thionine by the method of Nissl and hematoxylin, eosin. In the rat brain, neurotransmitter amino acids and neurotransmitters were identified. Statistical processing was performed using the W-Shapiro-Wills test to verify the normality of the distribution and the nonparametric Mann-Whitney U-test. The accepted significance level is p<0.05.

Results. Under the influence of the compound KGM-5 and “Picamilon” in the CA1 zone of the hippocampus, the number of normochromic neurons increased by 20 % and 16.6 %, respectively, hyperchromic pycnomorphic neurons and shadow cells decreased respectively by 5.8; 2.9 times and 6.3; 3.5 times, the index of alteration of neurons decreased by 6 times and 4.8 times, respectively, the area of ​​the perikaryon of these neurons increased by 39.7 % and 77.8 %, respectively, compared with KP (p<0.05). Both studied agents showed a less pronounced normalizing effect on the CA3 area of the hippocampus. The new compound KGM-5 showed a normalizing effect similar to “Picamilon” on the level of neurotransmitter amino acids and neurotransmitters in the brain of rats with ACVA.

Conclusions. Therapeutic administration of KGM-5 increases the survival of ventral hippocampal neurons, reducing the relative proportion of irreversibly altered cells, and helps to restore impaired levels of neurotransmitter amino acids and neurotransmitters in the brain of rats with ACVA.

The neuroprotective effect of the new compound KGM-5 corresponds to this comparison drug “Picamilon”

Published: May 2021

The aim. The aim of the work was to study the indicators of spermatogenesis in the lake frog, Pelophylax ridibundus (Pallas, 1771), in the zone of the influence of emissions from the Burshtyn Thermal Power Plant (TPP).

Materials and methods. Urinal sperm and testes samples were taken from male frogs under conditions of anthropogenic pollution (Burshtyn industrial area). Such parameters as sperm concentration in ejaculate, the number of live spermatozoa, total amount of actively mobile forms, and percentage of spermatozoa with progressive motion were determined by calculations in the hemocytometer. Testis samples were processed for routine histological method. The diameter of seminiferous tubules and histological abnormalities were studied.

Results. Studies have revealed that near the Burshtyn TPP industrial site, the sperm concentration in the sperm sample and the total number of motile spermatozoa of the lake frogs significantly decreased. The number of dead spermatozoa increases. Amphibians from polluted sites had histological abnormalities in testes such as dilation of the seminiferous tubules with sparse sperm. At the same time, the diameter of the seminiferous tubules in the animals from polluted site significantly decreased.

Conclusions. The impact of the emissions from the Burshtyn thermal power plant has an expressive reprotoxic effect that is manifested by depressive changes in testes tissue and gametes. The reproductive system of the lake frog is quite sensitive to environmental pollution. Sperm parameters and histological changes in testes are informative biomarkers and can be used for bioindication of technogenically transformed territories
Application of laboratory beta radiometry for quantitative indication of radionuclide concentration in plant samples
Authors: Ganzha Dmitro , Ganzha Dmytro , Sploshnoy Borys
Published: May 2021

The aim is to improve the beta-radiometric method of quantitative indication of the content of 90Sr and 137Cs in the counters of plant samples.

Material and methods. In the Chernobyl exclusion zone (ChEZ) in 2017, 2019, leaves of silver birch, black poplar, common reed, sedge were selected, which were dried, crushed, and used as calculating samples for beta radiometry and spectrometry. For measurements, a combined KRK-1 radiometer and a SEB 01-150 spectrometer beta-radiation energy were used.

Results. Currently, in plant samples from the ChEZ, the following are widespread: natural 40K, the concentration of which is usually less than 1 % in relation to the concentration of technogenic radionuclides 90Sr+90Y and 137Cs, therefore, when measuring 90Sr and 137Cs, beta radiation of 40K can be ignored. The measurements were carried out without a spectral filter and using a thin molybdenum filter. Without filter – show the count rate of 90Sr+90Y and 137Cs radiation. The filter transmits 2–3.5 % of the low-energy beta radiation of 90Sr and 137Cs and more than 95 % of the high-energy 90Y. The ratio of the count rate of 90Y pulses with and without filter is 2.14. The 90Sr concentration in the samples was determined from the results of measurements of 90Y, and 137Cs – through the fraction of the counting rate, which remains after deducting 90Sr+90Y. Comparison of the concentration of radionuclides measured by the method of beta-radiometry and spectrometry showed no significant difference between the results obtained by the two methods.

Conclusions. The beta radiometry method for 90Sr and 137Cs provides for measuring the counting rate of beta radiation from counting samples without a spectral filter and using a thin molybdenum filter. Based on the research results, a procedure for calculating the concentration of 90Sr and 137Cs in counting samples of plant leaves was developed

An Efficient (t,n) Threshold Secret Image Sharing Scheme Based on Thien-Lin Secret Image Sharing
Authors: Amitava Nag , Chattopadhyay Arup Kumar , Paramita Maitra
Published: May 2021

In a (t, n) threshold secret image sharing scheme (TSIS), a secret image is first encoded into n pieces, normally referred as shares or shadow images. Those share-images can be stored or transferred safely as individually a share-image cannot reveal
any detail about the secret image. The receiver or user of the share-images referred as participants. If at least t(≤n) share-images are submitted by the participants, the secret image can be recomputed. One of the most popular secret image sharing schemes was proposed
by Thien-Lin (2002). The authors had proposed two versions of the scheme. The first version of SIS by Thien-Lin is efficient, but lossy as the pixel values more than 250 (< 256) are truncated to 250. The second one is lossless, but it increases the size of the secret image
during preprocessing. In this paper, we propose a secret image sharing scheme based on Thien-Lin scheme. We consider a little loss in the reconstructed image which is maximum one per pixel (the loss can be one to five in Thien-Lin scheme) and keep the size of the secret image same. Although
buffer pixels may be added for the sake of programming, after reconstruction of the secret image the buffer pixels are easily identifiable and can be safely removed.

Published: May 2021

ABSTRACT The anesthesia for awake craniotomy (AC) is a consecrated anesthetic technique that has been perfected over the years. Initially used to map epileptic foci, it later became the standard technique for the removal of glial neoplasms in eloquent brain areas. We present an AC anesthesia technique consisting of three primordial times, called awake-asleep-awake, and their respective particularities, as well as delve into the anesthetic medications used. Its use in patients with low and high-grade gliomas was favorable for the resection of tumors within the functional boundaries of patients, with shorter hospital stay and lower direct costs. The present study aims to systematize the technique based on the experience of the largest philanthropic hospital in Latin America and discusses the most relevant aspects that have consolidated this technique as the most appropriate in the surgery of gliomas in eloquent areas.

Published: May 2021

ABSTRACT The spleen is one of the most frequently affected organs in blunt abdominal trauma. Since Upadhyaya, the treatment of splenic trauma has undergone important changes. Currently, the consensus is that every splenic trauma presenting with hemodynamic stability should be initially treated nonoperatively, provided that the hospital has adequate structure and the patient does not present other conditions that indicate abdominal exploration. However, several topics regarding the nonoperative management (NOM) of splenic trauma are still controversial. Splenic angioembolization is a very useful tool for NOM, but there is no consensus on its precise indications. There is no definition in the literature as to how NOM should be conducted, neither about the periodicity of hematimetric control, the transfusion threshold that defines NOM failure, when to start venous thromboembolism prophylaxis, the need for control imaging, the duration of bed rest, and when it is safe to discharge the patient. The aim of this review is to make a critical analysis of the most recent literature on this topic, exposing the state of the art in the NOM of splenic trauma.

A vacinação é uma das ações de saúde pública que tem colaborado com a diminuição da incidência das doenças imunopreveníveis. No entanto, as vacinas podem acarretar eventos adversos pós-vacinação. Assim, este estudo teve como objetivos: analisar a prevalência dos eventos adversos pós-vacinação em pessoas idosas; levantar os eventos notificados; identificar as vacinas que causaram eventos e verificar os eventos adversos pós-vacinação e as vacinas administradas que acarretaram internações no Estado de São Paulo, Brasil, nos anos de 2015 a 2017. Estudo descritivo, transversal, de abordagem quantitativa com base nas notificações de eventos adversos pós-vacinação registradas no Sistema de Informações do Programa Nacional de Imunizações. Os resultados mostraram que dentre as 15.196.080 pessoas idosas imunizadas, ocorreram 207 notificações de eventos adversos pós-vacinação, sendo 187 (89%) devido a evento adverso não grave e 15 (8%) por erro de imunização. A maioria dos acometidos era: do sexo feminino (86%); raça branca (49%); com idades de 60 a 69 anos (70%). Dentre as manifestações clínicas destacamos as reações nos locais das aplicações (84%). Constatou-se que 131 casos (64%) evoluíram para cura sem sequelas. Em relação às internações, verificou-se que duas pessoas (2%) foram hospitalizadas devido a efeito adverso grave, a primeira recebeu as vacinas: difteria/tétano adulto (dT), pneumocócica (Pn23) e influenza, e a segunda recebeu Pn23. Observaram-se informações incompletas nas notificações de eventos adversos pós-vacinação. Conclui-se que a notificação do eventos adversos pós-vacinação é essencial. Faz-se necessário o comprometimento dos profissionais no preenchimento adequado da notificação, e ainda, a supervisão da vigilância sanitária visando à qualidade da assistência prestada à pessoa idosa acometida por eventos adversos pós-vacinação.

O artigo analisa os discursos realizados pelo então Deputado Federal Jair Bolsonaro em torno da Lei Nº 12.528/ 2011, que estabeleceu a Comissão Nacional da Verdade (CNV). Entende-se que esses discursos, proferidos na Câmara dos Deputados e no Congresso Nacional, são essenciais para a compreensão de uma linguagem política negacionista sobre a ditadura civil-militar brasileira e dos conflitos suscitados pelo reconhecimento da memória. Debate-se como esses discursos reiteram a permanência do passado autoritário, mediante tentativas de manipulação do passado e de construção de versões alteradas dos fatos no presente. A pesquisa seguiu por evidenciar os argumentos de defesa da ditadura civil-militar e de associação da esquerda com a criminalidade, concluindo por refletir sobre suas sustentações a partir das visões da imprensa de 1964.

RESUMEN El deporte es una actividad que se práctica de forma recreativa o profesional. Quienes lo hacen profesionalmente en ocasiones reciben aportes económicos y logran estudiar una carrera profesional, lo que se conoce como carrera dual. No obstante, hay quienes presentan esta actividad como su trabajo. El objetivo general del estudio fue analizar los argumentos de los deportistas chilenos para referirse a la práctica deportiva como una actividad laboral; el objetivo específico fue reflexionar críticamente sobre el desarrollo de la carrera dual en Chile. Para comprender estos argumentos, se realizó un estudio cualitativo por medio de entrevistas activas semiestructuradas a deportistas de alto rendimiento (DAR) y recreativos, olímpicos y paralímpicos. Los resultados muestran que los atletas demandan reconocimiento como trabajadores públicos por medio de tres argumentos: económico, subordinación y dependencia e identidad. Las conclusiones y discusiones sugieren debatir el reconocimiento de ellos y ellas como trabajadores públicos.

The Effect of the PPPLF on PPP Lending by Commercial Banks
Authors: Anbil Sriya , Carlson Mark , Styczynski Mary-Frances
Published: May 2021

We analyze whether the Federal Reserve's Paycheck Protection Program Liquidity Facility (PPPLF) was successful in bolstering the ability of commercial banks to provide credit to small businesses under the Small Business Administration's Paycheck Protection Program (PPP). Using an instrumental variables approach, we find a causal effect of the facility boosting PPP lending. On average, commercial banks that used the PPPLF extended over twice as many PPP loans, relative to their total assets, as banks that did not use the PPPLF. Our instrument is a measure of banks' familiarity with the operation of the Federal Reserve’s discount window; this measure is strongly related to both the propensity to sign up for and to utilize the PPPLF. Further, using a similar instrumental variables approach, we find evidence that the availability of the facility as a backstop source of funds may also have supported bank PPP lending, especially for larger banks.

East African Literature and the Gandasation of Metropolitan Language – Reading from Jennifer Makumbi’s Kintu
Authors: Adeniyi Emmanuel
Published: May 2021

Jennifer Nansubuga Makumbi is, without doubt, one of the finest literary writers to have come out of East Africa. The Ugandan has succeeded in writing herself into global reckoning by telling a completely absorbing and canon-worthy epic. Her creative impulse is compelling, considering her narration of a riveting multi-layered historiography of (B)-Uganda nation in her debut novel, Kintu. With her unique style of story-telling and intelligent use of analepsis and prolepsis to (re)construct spatial and temporal settings of a people’s history, Makumbi succeeds in giving readers an evocative historical text. In narrating the aetiological myth of her people, Makumbi bridges metonymic gaps between two languages – core and marginal. She deliberately attenuates the expressive strength of the English language in Kintu by deploying her traditional Luganda language in the text so as to achieve certain primal goals. The present study seeks to disinter these goals by examining the use of Metonymic Gaps as a postcolonial model to construct indigenous knowledges within a Europhone East African text. The study also mines overall implications of this practice for East African Literature. I argue that, just like her contemporaries from other parts of Africa, Makumbi projects Luganda epistemology to checkmate European linguistic heteronomy on East African literary expression. Her intentionality also revolves around the need to bend the English language and force it to carry the weight of Luganda socio-cultural peculiarities. Consequently, her text becomes a locus of postcolonial disputations where the marginal jostles for supremacy with the core in East African literary landscape.
DÜŞÜNCE OLARAK SANAT YA DA KAVRAMSAL SANATIN ANLAM SORUNU ART AS AN IDEA OR THE MEANING PROBLEM OF CONCEPTUAL ART
Authors: SAMSUN Meysem
Published: May 2021

ÖZ
Sanatın varlığını oluşturan, kimi zaman onu tanımlayan kimi zaman da onun tarafından ortaya konan derin, tinsel anlamlar, düşünceyi de oluşturan ama dönüşümsel olarak onun da nesnesi olan kavramları anlamlandırma, hatta bu anlamları yıkıma uğratarak onları her daim değiştirme eğilimi göstermiştir. 1960' lı yıllardan sonra plastik sanatlarda ve onun ortamında büyük bir değişim/dönüşüm yaşanmıştır. Bu değişim/dönüşüm sanat ortamında küçümsenemeyecek kadar etkili olmuş ve onu dönüştürmüştür. Bu büyük dönüşüm sanatın nesneye karşı duyduğu ilginin azalması olarak ifade edilebilir. Başka bir deyişle bu ilgi azalması, sanatın nesneye olan ihtiyacının azalması sonucunu doğurduğu kuşkusuzdur. Bu bağlamda kavramsal sanat sözcüklere boğulmuş düşünceleri kutsar hale gelmiştir. Artık sanat için, önemli olan nesne değil, düşünce olmuştur. Önceleri, estetik kaygıları önceleyerek varlık kazanan yapıt, estetiğin felsefe kavramlarına eklediği yeniliklerle değişime uğramış ve Modernizmin geliştiği bütün aşamalarda bu yeniliği hissettirmiştir. Makalede, sanat içerikleriyle tanımlanmış olan kavramların sanat nesnesiyle kurduğu ilişkilerin yapısı kavramsal sanatta anlam problemi açısından araştırılmaya çalışılacaktır. Yapıtın anlamla kurduğu neden- sonuç ilişkisi içinde eser üzerinden hareketle irdelemeye çalışılacaktır.

In vivo tissue-specific chromatin profiling in Drosophila v1
Authors: M. Weake Vikki , P P Jauregui-Lozano Juan
Published: May 2021

Chromatin regulation plays an essential role in many nuclear processes, and genome-wide chromatin profiling approaches contribute to understanding how chromatin regulates cell homeostasis. Chromatin dysregulation lies in the heart of many human diseases, which most of them have a tissue-specific nature. Because of the physiological similarity of Drosophila and humans, tissue-specific studies can be performed using fruit flies. Here, we present an improved nuclear tagging approach that allows for efficient purification of cell-type specific nuclei from Drosophila increasing yield and stringency. Using this protocol, we purified photoreceptor neuron nuclei, and demonstrate the feasibility and high quality of chromatin accessibility profiling as well as profiling of histones and histone modifications, using Omni-ATAC and ChIP-seq, respectively. Last, we describe a modification to the nuclei purification protocol that allows for application of recently developed CUT&Tag and demonstrate that CUT&Tag outperforms traditional ChIP-seq, although protocol might require further optimization.

Published: May 2021

Монография посвящена исследованию вопроса соотношения «первой философии» как учения о всеобщем единстве мышления и бытия с философией права как философско-специализированной наукой. В ней исследуются методологические и общетеоретические основания интерпретации классической философии права, проблемы монизма и дуализма в обосновании правовой теории, вопросы отношения права и нравственности, права и религии, Абсолюта в праве. Рассматривается понятие абсолютной свободы как парадигмы немецкой классической философско-правовой мысли. Показано, что на этой основе в классической философии права Канта, Фихте, Гегеля преодолевается как парадигма субстанциального естественного права, так и доминирующая до настоящего времени парадигма общественного договора. Монография адресуется научным работникам в области истории философии и теории права, юристам, преподавателям, аспирантам, студентам, а также всем, кто интересуется вопросами философии права.

Published: May 2021

This study intended to identify which referent features are more frequently selected in the naming of the concept class of places and, in turn, determine which are the preferred conceptualizations in Mapudungun. This language is mainly spoken by Mapuche people in central and southern areas of Chile and in the Central-West area of Argentina. To identify the features of this conceptualization, a cognitive-semantic analysis of the conceptual patterns of 112 nominal compounds pertaining to the concept subclasses of natural places (intervened and non-intervened) and non-natural places (installations and territorial divisions) was conducted. Results show that, for non-intervened natural places, an entity present in the natural place is preferably selected in the name, whereas for intervened places, an agricultural activity or an animal associated to the place is preferably chosen. Concerning installations, the preferred conceptual pattern specifies, by means of the constituent ruka ‘house’, the man-made nature of the place. Regarding territorial divisions, the preferred naming pattern combines two place concepts. This information is crucial for the creation of neologisms in Mapudungun because it guarantees that newly formed lexical units are coherent with the Mapuche worldview and do not import foreign models.
Effective Teaching Strategies and Behaviors of Legal Translation Lecturers in Spain
Authors: Martínez-Carrasco Robert
Published: May 2021

Framed within the current accountability policies in higher education, under the strains of global competition and the internationalization of universities worldwide, this article examines effective teaching as a pillar of teaching quality in higher education among legal translation lecturers. By linking certain teaching and learning styles to the different dimensions of effective teaching (instructional, organizational, and emotional), the teaching profile of legal translation lecturers in Spain at undergraduate level is analyzed. In addition, student-centered teaching approaches are connected to the use of classroom strategies and methodological resources that characterize effective teaching. The findings of this study, obtained through the distribution of the tamufq questionnaire (Teaching and Assessment Methodology of University Faculty Questionnaire) among legal translation lecturers at undergraduate level in Spain, suggest that those lecturers who adopt a post-positivist approach in their classroom display a greater variety of teaching behaviors and strategies associated with both effective curriculum implementation and higher quality teaching than those who are closer to traditional, positivist approaches. These findings may be particularly useful in the design and implementation of continuous professional development courses and pedagogical training of lecturers.
Construcción y transformaciones de las identidades académicas de estudiantes doctorales mediante la citación
Authors: Calle Arango Lina , Ávila Reyes Natalia , Meneses Alejandra
Published: May 2021

Los desafíos y tensiones identitarias de los doctorandos constituyen un tema de creciente relevancia. Una manera de estudiarlo es mediante los propósitos de citación, pues para participar del mundo académico el investigador en formación debe posicionarse en el diálogo con otros autores y con los avances de su comunidad discursiva. Esta investigación utiliza el marco teórico de las Literacidades Académicas para analizar la relación entre citación y construcción de identidad académica en estudiantes doctorales desde una perspectiva longitudinal. Se analizaron los propósitos de citación en las introducciones de tres versiones de la revisión de literatura de cuatro doctorandos en Educación y se integraron con sus testimonios, recogidos mediante entrevistas basadas en textos. Los resultados muestran cómo los doctorandos eligen propósitos por hábitos, estilos o filiaciones disciplinarias, así como por la construcción de la imagen que desean proyectar como investigadores y que los sitúan a medio camino hacia una autopercepción como tales. Este contraste permite la construcción de una identidad académica híbrida o múltiple. Finalmente, este estudio aporta en mostrar metodológicamente cómo vincula el análisis de la intertextualidad con las perspectivas de los escritores.

Authors: Narváez Escobar Sindy Paola
Published: May 2021

Esta investigación tuvo como objetivo fortalecer los procesos de apropiación del léxico ette taara (familia lingüística) en estudiantes del ciclo Moomate (preescolar) de la Institución Etnoeducativa Departamental del Resguardo Issa Oristunna, en Sabanas de San Ángel (Magdalena, Colombia). A través de un trabajo de campo, se recolectaron los datos mediante observación participante, encuestas, entrevistas, procesos dialógicos y grabación del léxico. Se concluyó que los etnoeducadores entienden la necesidad de que sus estudiantes se apropien de su lengua materna, pero carecen de materiales didácticos fundamentales para su enseñanza. Esto derivó en la creación de una aplicación móvil como herramienta de aprendizaje.

Authors: Pereira da Silva Keury Carolaine , Pires de Assis Emanoel Cesar
Published: May 2021

This research analyzed how the search for self-representation in literature claims the presence of peripheral groups and differs in the specificities of language and aesthetics, such as the case of violence in the work Capão Pecado, by Ferréz. Therefore, the considerations about this theme were expressed, from the perspective of those who practice and are the target of this impetus. In order to reach the scope of this research, some theorizations were considered. Finally, it is considered that the book suggests a reflection about the common perceptions of favelas and their residents, by providing new views of them.
Algunas reflexiones sobre la literatura de Walter Benjamin como antecedente de los estudios sobre la memoria
Authors: Pérez Victoria , Baéz Peralta Gerardo
Published: May 2021

Los estudios sobre la memoria han contribuido a clarificar la forma en que la identidad está configurada por nuestros recuerdos, a su vez cimentados y transmitidos en un plano social. En este artículo, revisamos dos ensayos de Walter Benjamin, precursor en la discusión del carácter social de la memoria y del origen, realización y efectos de la rememoración, y los empleamos para reflexionar sobre la naturaleza de la literatura tal y como se la concibe cuando contribuye a la labor de representar y difundir imágenes de enclaves del pasado y a reflexionar sobre los procesos de la memoria colectiva.

Authors: Agudelo Olarte Felipe
Published: May 2021

Los Cuentos jasídicos, de Martin Buber, son abordados en el presente artículo desde la presencia de la danza como motivo temático en algunos de los relatos, buscando así acercarse al pensamiento del autor a través de su obra literaria. En el texto se relacionan los relatos con elementos de estructura narrativa; se presenta el diálogo como marco narrativo de los cuentos en los contextos de lo incomprensible, la identidad, la comunidad-amistad y la muerte; finalmente, se propone la danza como «esfera del entre» en los cuentos y condición de celebración del encuentro yo-tú, efectuado en quienes participan de la trama.

Jamaican and Haitian Creole are taken as points of comparison for their more advanced state of consolidation. Posts from Facebook groups gathered between February 2016 and July 2020 as the main source of data were complemented by 2015 data on San Andrés linguistic landscapes. The main finding is that, due to a favorable change in language attitudes both locally and globally, San Andrés-Providence Creole is entering into the domain of writing.
The Hour of the Star Through Media Lenses: A Tribute to Clarice Lispector (1920-2020)
Authors: Alves Araújo Gilberto , Rodrigues Sousa Eliene , Da Silva Lopes Raquel
Published: May 2021

The criticisms of Clarice Lispector’s The Hour of the Star (1977) were analyzed by (re) evaluating its relevance and the legacy of its author. After a critical review of the texts in popular publications, it was found that, in Brazil, the debates about the novel were centered between explicitness and introspection, social commitment and aesthetic sublimation. Foreign critics, on the other hand, raised Lispector’s ability to reach diverse audiences and the readability of her work, including disputes over her prestige as an author among other great writers and the relevance of her compositions.

Authors: Ferrer Botero Alberto , Londoño Arredondo Nora Helena , González-Gómez Difariney
Published: May 2021

El objetivo de esta investigación fue determinar si las relaciones entre rasgos patológicos, creencias disfuncionales de la personalidad y trastornos de la personalidad son, en efecto, las predichas tanto desde el modelo alternativo (American Psychiatric Association, 2013a, 2014) como desde la teoría cognitiva de los trastornos de la personalidad (Beck et al., 1995, 2005). La muestra fue de 80 pacientes con trastornos de personalidad (37.5% hombres y 62.5% mujeres; edad media: 30.7; DE = 10.5) evaluados con una encuesta sociodemográfica y de antecedentes psiquiátricos, además de las siguientes pruebas: MINI, IPDE, PID-5, PBQ-SF, y CCE-TP. Se probaron tres grupos de hipótesis: a) existencia de relaciones significativas entre rasgos patológicos y trastornos de la personalidad; b) existencia de relaciones significativas entre creencias disfuncionales y trastornos de la personalidad; y c) existenca de relaciones significativas entre rasgos patológicos y creencias disfuncionales. Los tres grupos de hipótesis se cumplieron de forma muy adecuada para los trastornos de la personalidad antisocial, narcisista, paranoide y esquizoide, pero no para el trastorno de la personalidad histriónico. Se concluye que esta investigación representa un respaldo empírico para los modelos de rasgos patológicos como para los de creencias disfuncionales.

O processamento industrial aumenta a vida útil dos alimentos e confere praticidade aos consumidores. O objetivo do trabalho foi avaliar o perfil e a preferência dos consumidores de alimentos industrializados da cidade de Guanambi/BA, durante o período de março a agosto de 2017. Para o estudo foram realizadas entrevistas com 378 pessoas, usando um questionário de múltipla escolha, conforme tamanho da população, homogeneidade do público-alvo e a quantidade de erro amostral admitida (5%). O consumo de alimentos industrializados foi maior entre o público feminino (75,1%), jovem (33,6%), e em sua maioria, com 2º grau completo (43,7%) e composição familiar entre dois e quatro membros (78,3%). A maioria dos respondentes possuía renda entre um e três salários-mínimos (76,3%). Os consumidores responderam por optar por uma alimentação prática (49,5%), com frequência entre três e cinco dias por semana (32,3%). Os entrevistados disseram consumir alimentos ricos em gorduras, açúcar e sal, entretanto, 80,7% dos respondentes consideraram alimentos industrializados não nutritivos, e a maioria (79,4%) afirmou que deixaria de ingeri-los caso o consumo fosse prejudicial à saúde. Dessa forma, o consumo de alimentos industrializados pode estar associado com  fatores culturais, de renda e de disponibilidade de tempos para o preparo das refeições individuais e/ou da família, sendo que o público jovem e feminino apresentou o maior padrão de consumo.

Abstract

The industrial food processing ncreases shelf life and confers convenience to the consumers. This study aimed to evaluate the profile of processed foods consumers in the city of Guanambi-BA from March to August 2017. 378 consumers were interviewed by choosing a multiple-choice questionnaire taken into account population size,  target public homogeneity, and sampling error rate at 5%. In Guanambi, that profile revealed on its majority women (75.1%), youngers (33.6%), with secondary education (43.7%), coming from a family size of two to four members (78.3%). Most interviewees earn one to three minimum wages (76.3%). The reason why they choose this kind of food is due to the practicality (49.5%) with a varying frequency of three to five days a week. Interviewees admit consuming food with a high content of fats, sugar, and salt. However, a little over four-fifths (80.7%) consider processed food non-nutritive. Nearly 80% would consider stopping eating them if it were harmful to health. Thus, such consumption may be related to cultural factors, income, and available time to prepare individual and/or family meals, with notably dietary patterns among young and female interviewees.
