Identificação de fatores determinantes da severidade das lesões sofridas por pedestres nas rodovias federais brasileiras entre 2017 e 2019: Análise via regressão logística multinomial
Authors: Miranda Rian , Da Silva Walber Paschoal , Dutt-Ross Steven
Published: May 2021

A mobilidade a pé é uma das principais formas de deslocamento da população brasileira, representando 41% das viagens realizadas no país em 2016. Entretanto, o compartilhamento do espaço entre pessoas e veículos motorizados em locais desprovidos de infraestrutura adequada tem provocado situações de conflito, aumentando os riscos de ferimentos e fatalidades entre os transeuntes. Neste estudo, foi realizada uma análise sobre os fatores determinantes da severidade das lesões sofridas por pedestres nas rodovias federais brasileiras no período entre 2017 e 2019. Para tanto, foram utilizados dados oficiais da Polícia Rodoviária Federal para a construção de um modelo de regressão logística multinomial, que descreveu o estado físico dos pedestres a partir das variáveis explicativas presentes na base de dados. Os resultados obtidos apontam que: pedestres atropelados por veículos de grande porte, como caminhões, ônibus e utilitários apresentam maiores chances de morte; fases do dia com menor luminosidade natural, como a plena noite, o amanhecer e o anoitecer, oferecem maiores riscos de lesões graves e fatalidades; perímetros urbanos oferecem menor risco de fatalidades em relação às áreas rurais; pedestres do sexo masculino têm maiores chances de apresentarem ferimentos graves ou virem a óbito; pistas múltiplas e finais de semana oferecem maiores chances de morte ou lesões graves ao pedestre. Por fim, foi identificada uma tendência de aumento anual nas chances de lesão grave (9,9% ao ano) e morte (3,3% ao ano) entre os pedestres brasileiros, bem como maiores riscos à integridade física dos pedestres das regiões norte, nordeste e centro-oeste.

Authors: Islam Maisha , Burnett Tiffany-Lily , Collins Sarah-Louise
Published: May 2021

This case study describes a staff-student partnership project from the perspective of three staff members based across independent departments within a UK higher education institution (HEI) and its students’ union. The authors, drawing upon an intersecting passion for advancing student equality, diversity, inclusion, widening participation and student engagement, developed a cross-collaborative and student-centred partnership project to create a series of guides specifically for underrepresented student groups. The guides, which sought to provide appropriate information and guidance in order to actively enhance students’ overall experience whilst navigating university life, were developed and co-created through lived student experience. This case study critically reflects upon this form of partnership, along with its benefits and challenges, and considers its contribution to literature on staff-student partnership beyond the formal realm of learning and teaching.
Efficient fractionation of corn stover by bisulfite pretreatment for the production of bioethanol and high value products
Authors: Tan Liping , Liu Zhongyang , Liu Tongjun , Wang Fangfang
Published: May 2021

Fractionation of corn stover (CS) was carried out by bisulfite pretreatment in order to improve the production of bioethanol and high-value chemicals. Firstly, the optimum bisulfite pretreatment conditions of CS (170 C, 30 min, 7% NaHSO3, 1% H2SO4) were identified. Next, a biorefinery process of bisulfite pretreatment for CS was proposed. CS was separated into solid and liquor components using such pretreatment. The solid components were employed for bioethanol production by quasi-simultaneous saccharification and fermentation (Q-SSF). The bisulfite liquor was fractionated into hemicellulosic sugars and lignin by different types of resins. It was shown that CS components could be effectively fractionated through bisulfite pretreatment in combination with resin separation to produce bioethanol, hemicellulosic sugars, and lignosulfonate.

Published: May 2021

In order to realize the resource utilization of the Pinus koraiensis pine cone, the polysaccharides were obtained by a traditional hot water extraction process, and the optimal extraction process was confirmed. The effects of a traditional hot water, alkali, and ultrasound assisted extraction on the yield and properties of polysaccharides were studied. The structure, monosaccharide composition, and content of polysaccharides obtained by different extraction methods were analyzed by means of Fourier infrared chromatography and liquid chromatography. Effects of polysaccharides extracted by different methods on the antimicrobial activity of Staphylococcus aureus and Escherichia coli were studied. The scavenging effect of DPPH free radicals were also examined. The optimum condition of the hot water extraction was identified as an extraction temperature of 100 °C, a ratio of material to water at 1:16 (w/v), an extraction time of 4 h, and a yield of polysaccharide at 10.2%. In comparison, the yield of the pine cone polysaccharide was improved significantly to 29.1% by using NaOH solution extraction method. The FTIR spectra of polysaccharides showed that the samples possessed the typical chemical structure of a polysaccharide.

Authors: Chen Feng , Wang Baichuan , Xia Xinghua
Published: May 2021

The development of a formaldehyde-free wood-based panel is a major research direction in the wood-based material industry. Previous research has demonstrated that nitric acid activated fibers and coupling agents could be utilized to manufacture formaldehyde-free medium-density fiberboards. Herein, based on the chemical characteristics of wood, nitric acid and tannin were applied in formaldehyde-free particleboard, featuring suitable mechanical properties and water absorption resistance. The results of modulus of rupture (MOR), surface bonding strength, internal bonding strength, and 2 h moisture thickness swelling (TS) of formaldehyde-free particleboard (that was synthesized at optimal conditions and satisfied the China National Standards GB/T 4897 (2015) and GB/T 17657 (2013)) are discussed. The investigation of the technological conditions on bond performance showed that when the particleboard was bonded with the conditions of 20/80 nitric acid/particles mass proportion, 50% tannin concentration, and 135 °C temperature, the MOR, surface bonding strength, inner bonding strength, and 2 h TS were better than that of the particles with urea formaldehyde resin adhesive. The synthesis mechanism was studied by both Fourier transform infrared spectroscopy and wide-angle X-ray diffraction, and the chemical composition indicated polycondensation of furfural and tannin, and hydrogen bonding of hydroxyl groups as the reaction mechanism between nitric activation and the tannin coupling agent.

Since the beginning of the pandemic, there is currently no specific treatment, however some drugs, after systematic reviews and meta-analysis have been positioned as potential treatments (dexamethasone, tocilizumab, baricitinib), however, other drugs with therapeutic potential are being investigated, such as Polymerized type I collagen (Fibroquel). Material and methods: Adult patients are admitted to the study from December 2020 to January 2021, with prior informed consent, carriers of viral pneumonia confirmed by axial tomography, secondary to infection by Sars Cov2 virus identified by RT-PCR or antigen test, who also present severity data (dyspnea, desaturation -saturation at room air of 92% or less-, persistent fever), as well as inflammation markers (D-dimer 1000ng/ml±100; ferritin> 300mg) and that allow treatment with Polymerized type I collagen (Fibroquel®) at home or in a hospital area. Results: We include data from 35 patients, 19 (54.3%) women and 16 (45.7%) men, with a median age of 51.0 (38.0-76.0) years. The number of patients with a history of previous comorbidities was 34 (97.1%) and 20 (57.1%) had multiple comorbidities (3 or more synchronous comorbidities). The most frequent comorbidities among these patients were obesity in 94.3%, DM2 62.9%, Arterial hypertension 60.0%, COPD 14.3%, heart disease 8.6%, nephropathy 5.7%, in addition to SLE and trisomy 21, both in 2.9% of patients. In the baseline evaluation laboratory, we found that 33 (94.3%) patients had lymphocytopenia and 3 (8.6%) had thrombocytopenia. Median D-Dimer and Ferritin serum levels were 1,200.0 (990.0- 1,800.0) ng/mL and 394.5 (320.0-492.5) ug/L, respectively. The neutrophil-lymphocyte index was calculated, which on average was 10.8 (8.0 - 14.7) and an ABC-GOALSclx index of 14.0 (11.0 - 16.0) was calculated, which translate severe disease and an indication of stay in an intensive care unit. Relation to the pulse oximetry at ambient air in the baseline evaluation, we found that the median O2 saturation was 88.0% (86.0% - 89.0%). The median number of days of evolution from the onset of symptoms to the moment in which treatment with Fibroquel was started was 8.0 (7.0-9.0) days. The pulse oximetry quantified 7 days after the start of treatment had a median of 94.0% (93.0-95.0%); Regarding the measurement of prognostic biomarkers, the median d-dimer and ferritin in serum measured at 7 days of follow-up were 656.0 (497.0 - 697.5) ng/mL and 394.5 (320.0-492.5) ug/L, respectively. Conclusion: Polymerized type I collagen (Fibroquel) is an effective drug in patients with inflammatory and hypoxemic pneumonia secondary to Sars COV 2 infection, favoring clinical improvement and favoring extubation, oxygenation, and inflammation indices, as well as a biosafety profile that ensures its use without restrictions in these patients.

Published: May 2021

Suicidal ideation in elderly is rarely a society’s concern even though elderly is the age group most vulnerable to suicide. This study was conducted to prove the effect of perceived burdensomeness, thwarted belongingness, religiosity, and demographic factors (gender and education level) on suicidal ideation in the elderly. The subjects of this study were 230 respondents aged 60 years and over who were obtained using accidental non-probability sampling techniques. The measuring instrument used were the adaptation and modification of the Geriatric Suicide Ideation Scale, the Interpersonal Needs Questionnaire, and the Centrality of Religiosity Scale. The validity test of the instrument was carried out using Confirmatory Factor Analysis (CFA), while the hypothesis testing was carried out using multiple regression analysis. The results showed that there was a significant effect of perceived burdensomeness and the ideological dimensions of religiosity. The results of this study are expected to be an input for readers to pay more attention to the perceived burdensomeness and ideology of religiosity in the elderly as factors that can influence suicidal ideation. Subsequent researchers can also develop this research by adding other independent variables to be analyzed, such as health conditions and living arrangements.

Tangerang is a city whose people consist of various ethnicities or religions, such as Muslims, Christians, Catholics, and Buddhists. Even in Tangerang, there are quite a lot of temples / temples. In the last 20 years, the people of Tangerang City have never faced horizontal conflicts between religious believers. But interestingly, based on the results of the Setara Institute study in 2018, Tangerang as a city has a tolerance index of 4.58 from a range of scores of 1-7. This figure puts Tangerang in the 61st position of the 94 cities surveyed. These results can be said to be low. Of course, this is somewhat different from the phenomenon which recorded the absence of horizontal conflicts in Tangerang City. The purpose of this research is to see a picture of religious maturity and religious tolerance in the people of Tangerang city. This study used a quantitative approach, target participants in this study were 150 (n = 150) participants. The research instrument was a questionnaire containing statements / items related to religious tolerance. Data was collected by means of online administration because this study was conducted during the Covid-19 pandemic. The results of the mean difference test show that there is no significant difference, both in terms of religious tolerance and religious maturity based on the demographic group of age, gender, and education. But in terms of histogram distribution, it shows the outlier score on the variable of religious maturity. Therefore, in general, demographic factors do not affect the variation of religious tolerance and religious maturity. However, the religious maturity score of the people of Tangerang City is relatively low.

The fleet of developing countries consists of motorcycles and cars. This heterogeneous traffic condition has its advantages and disadvantages, which results in conflicting points of view (e.g., motorcyclists enjoying a higher mobility while car drivers resent their decreased speed). In this paper, we corroborated the notion that traffic evaluation depends on the chosen metric (e.g., vehicle flow, fuel consumption, monthly costs) and the point of view (driver, rider, and policy makers). To this effect, we studied a mixed traffic condition, considering that the vehicle performance is affected by three scales: engine, vehicle, and traffic. We modeled the engine using empirical correlations of power and energy efficiency, the vehicle based on a balance of propulsive and resistive forces, and traffic with a cellular automata model. We simulated 189 traffic conditions and evaluated vehicle flow, average energy consumption, total CO2 emission of the road, and monthly costs. We also discussed the results from the point of view of the driver, rider, and society. We concluded that the optimal condition depends both on the choice of metric and point of view, and that is not appropriate to use results from homogeneous traffic to analyze heterogeneous traffic conditions, even if both scenarios present the same total vehicle flow.

Quinoa (Chenopodium quinoa Willd) is a pseudocereal with a high nutritional potential and a significant content of bioactive compounds, which is consumed mainly by the inhabitants of the South American Andes. The aim of this study was to evaluate the protein content, total phenols, and antioxidant activity of quinoa grains of the Salcedo INIA, Pasankalla, and Negra collana varieties, germinated for 24 and 48 hours at 35 °C. Organic quinoa grains were grown in the Andahuaylas province in Peru, at an altitude of 3582 m. The protein content was determined through the Kjeldahl method, total phenols, in turn, by spectrophotometry with the Folin-Ciocalteu reagent, and the antioxidant activity of the DPPH type were registered. The data were analyzed through an Analysis of Variance (ANOVA), a Tukey test, and Pearson’s correlation at 5% significance. The germinated quinoa grains showed a considerable increase (p < 0,05) in their protein content, total phenolic compounds, and antioxidant activity, as well as a strong positive correlation with the size of sprouts during the germination time. Therefore, germinated quinoa could be considered as a promising product for human nutrition and health.

Published: May 2021

Plant-based feed additives, also known as phytobiotics, show great promise to compensate deficiencies of important biologically active substances in the diet. Therefore, this study aimed to evaluate the effect of Germivit on the feed supplement of cattle of different ages. In the first experiment, four groups of 9-month-old Simmental calves (10 animals in each group) were fed with Germivit at 0.0, 0.5, 0.7, and 0.9 g kg-1 live body weight, respectively. In the second experiment, three groups of pregnant cows (10 animals in each group) received Germivit at 0.0, 0.25, and 0.50 kg-1 live body weight, respectively. The morphological composition of the collected blood was studied using a PCE-90vet automatic hematology analyzer. The blood biochemical composition was studied using a Stat Fax 1904 biochemical analyzer, and the immunological status of the animals was evaluated using generally accepted methods in veterinary medicine: immunocompetent cells by spontaneous rosette formation; immunoglobulins by the radial  immunodiffusion method; phagocytosis by using S. aureus culture; serum lysozyme activity by the photoelectrocolorimetric method; and bactericidal activity of serum by determining the degree of growth inhibition of the mixture of daily  culture of E. coli in a nutritive culture broth. Germivit contributed to the improvement of the biochemical and immunological parameters in the calves. In the cows, an increase in the morphological parameters of blood was observed, their immune status improved, and their calves were born with high rates of natural resistance and health. Germivit had a positive effect on the functional state of cattle.

Published: May 2021

Quinoa is a promissory crop in the Andean region, on average, grain yield was 1.62 t ha-1 with nearly 2,000 t in the year 2017. This study examined the response of quinoa to the radiation transmission, growth, and development of the crop in different stages, under three planting densities in order todetermine the differential responses and identify which aspects are determinants in the planting and development process and crop yield. For the present experiment, quinoa was sowed in three differentdensities: D1 65,500, D2 83,333, and D3 156,250 plants per ha. This study measured the percentage of canopy PAR transmission, distribution of matter on root, stem, leaf, and panicle, leaf development in leaf area and leaf area index, yield components, weight of 1,000 grains, and harvest index. The results showed that sowing density had no impact on PAR transmission, lower sowing densities obtained the best dry weight of panicle at the end of the production cycle, better yields, and best grain weight. To conclude, the sowing density affects different yield components, while all of them allow theplant to generate the best response within the production cycle.

Published: May 2021

Lulo (Solanum quitoense Lam.) is a fruit tree of Andean origin of national economic importance in Colombia, which constitutes an important source of employment for farmers and their families. Vascular and root wilt caused by the fungus Fusarium oxysporum is one of the most limiting diseases in the production of this species, causing low yields and considerable economic losses. As an effective control alternative for this pathogen, the identification of genotypes with resistance that can be used in breeding programs is being considered. The objective of this work was to evaluate the response of 22 lulo genotypes to the artificial inoculation of Fusarium oxysporum to identify possible sources of pathogen tolerance. F. oxysporum was inoculated on 22 genotypes of lulo plants following the method of wounded roots through artificial cutting. Distilled water inoculation and “La Selva” resistant lulo hybrid was used as control. The traits evaluated correspond to plant height, stem diameter, days to the onset of symptoms, incidence and severity. The fungus isolation was highly aggressive in S. quitoense and S. hirtum, with 96 and 84% severities, respectively. Five resistant genotypes were identified, namely 15C, 36B, HSF1, HSF10, and HSF36, which presented incidences and severities of 0% and can be considered for multi-environmental evaluation tests to determine their productive potential or they can be considered as parents for breeding programs of the species. Other genotypes, such as 15B and HSF15, showed average severities of 28 and 20%, respectively; however, thesetwo genotypes survived throughout the experiment, suggesting tolerance to the pathogen.

Selectivity index is a way of assessing the discrimination of herbicide to a given crop by observing its effects on the crop and the weeds. The aim was to obtain the selectivity index of indaziflam herbicide to sugarcane cultivar IACSP95-5000 as a function of five weed species in two soils textures. The experiment was carried out in a greenhouse at Piracicaba, São Paulo, Brazil. The treatments consisted of indaziflam doses (0; 12.5; 25; 50; 100; 200; 400; 800 and 1,600 g of the active ingredient (ai) ha-1), applied in pre-emergence of the sugarcane and of the weeds Urochloa decumbens, Urochloa plantaginea, Digitaria horizontalis, Panicum maximum and Rottboellia cochinchinensis. In sandy loam soil, a 100% control for all weeds was provided at 25 g ai ha-1. In clay soil, for D. horizontalis the 90% reduction in total dry mass (ED90) was obtained at 25 g ai ha-1, for R. cochinchinensis at 193 g ai ha-1, for U. plantaginea at 152 g ai ha-1, for P. maximum at 124 g ai ha-1, and for U. decumbens at 94 g ai ha-1. Indaziflam was selective to IACSP95-5000 in both soils, with 10% of reduction in dry mass (ED10) at 137 g ai ha-1 for soil with a sandy loam texture and 353 g ai ha-1 for clay soil. The selectivity index was higher than 1 for all weeds in clay soil. It was not possible to obtain the selectivity index for sandy loam soil due to species susceptibility to the herbicide.

Published: May 2021

The paper explores music preferences of elementary school pupils for classical music and the influence of familiarity with music on their music preferences. As a part of the research, a questionnaire, and a sound questionnaire as its integral part, was administered to 238 pupils attending the second, the fifth and the eighth grade of elementary school.  The results confirm that younger pupils, compared to the older ones, show greater preferences for classical music. In addition, the influence of gender on preferences for classical music was also confirmed, while attendance of extracurricular music lessons was not proven to be  a significant predictor of the pupils’ preferences for classical music. It was also noted that familiarity with music is a significant factor influencing pupils’ music preferences. The results confirm that pupils show the lowest music preferences for the 20th-century music, which has significant implications for music-pedagogical theory and practice.Key words: classical music; elementary school; music preferences---U ovom radu istražuju se glazbene sklonosti učenika osnovne škole prema klasičnoj glazbi i utjecaj poznavanja glazbe na njihove glazbene sklonosti.

“Eyes Have No Border”. Presencing the Slovenian-Hungarian Border in Goričko and the Rába Valley
Authors: Gradišnik Ingrid Slavec , Hirnök Katalin Munda
Published: May 2021

The article draws on the written and oral memories of people living along the border between Slovenia (Goričko in Prekmurje) and Hungary (the Rába Valley). They are presented as comments on a century-long process of political changes in this borderland and demonstrate a plethora of ways in which border shifts intrude on people’s everyday lives. People’s concern with the border is reflected in the fact that it is a topic that emerges in any conversation with individuals living next to it, whether in the context of work, family, daily errands or stories of the past and present. In this article, informed by two concepts–border and memory– we present memories and perceptions of the border as they are expressed in casual comments or observations and semi-structured conversations with interviewees in the field. Life in borderlands is always localized, and there are visible divergences in the experience of the border on the Slovenian and Hungarian side. In Prekmurje, historical events along the border, especially the post-Trianon one, and the memory of these events are perpetuated through anniversaries of the annexation of Prekmurje to the Kingdom of SCS, whereas in the Rába Valley, memories especially relate to the Iron Curtain period. In a much more poignant way, they also constitute the present Slovenian community in ethnic terms as they are mediated in their vernacular.
Changes in Pumpkin Seed Oil Production and Local Communities. Examples from the Hungarian-Slovenian Borderland
Authors: Mód László
Published: May 2021

The present study examines the heritagization processes associated with pumpkin seed oil, a product typical of the Slovenian-Hungarian borderland, that have evolved since the 2000s in a settlement in the Őrség region of Hungary and a settlement in the Slovenian region of Goričko. The study explores how innovations — in our case, the introduction and spread of new varieties of pumpkin — have transformed seed oil processing technologies, and the impact that this transformation has had on the culture of the local communities. Both examples can be regarded as success stories in their own way, since the examined communities can be said to have taken ownership of, and “appropriated,” this aspect of their traditional culture in advance of other settlements in the same region by connecting and binding it to their own locality. Today, there can be no doubt that these two settlements have “earned the right” to be permanent representatives of this unique cultural heritage and to exploit the opportunities it offers.

Authors: Babai Dániel , Szépligeti Mátyás , Tóth Antónia , Ulicsni Viktor
Published: May 2021

Traditional ecological knowledge of plants is an important aspect of scholarship in relation to land use and contributes to the sustainable use and management of natural resources as well as to the monitoring of changes in the natural environment. The aim of the present paper was to examine traditional ecological knowledge in Hungarian communities in Slovenia in connection with knowledge of the plants growing in the region, their local names, and their uses. We quantified the earlier role of the utilized plant species in order to determine the former significance of certain species. We carried out structured interviews with a total of 20 individuals in three studied settlements. In the Hungarian communities in Slovenia, we uncovered knowledge of a total of 130 folk taxa. Of these, 123 taxa have local names. The majority of the folk taxa can be correlated with a single biological species. A significant proportion of the known species were utilized in some way, most of them as medicinal plants, wild edible plants, or ornamental plants. As in other farming communities, the most important species are mainly woody plants, which include the common hornbeam, the common juniper, and the silver birch. Among the herbaceous plants, utilization of the dandelion, nettle, and bulrush was significant. Members of the older generations living in the Hungarian communities in Slovenia still retain knowledge of plants that were once used on a daily basis, along with their local names and the traditional ecological knowledge connected with their earlier use.
Pascal’s Hexagram and Desargues Configurations
Authors: Chipalkatti Jaydeep
Published: May 2021

This paper solves an enumerative problem which arises naturally in the context of Pascal’s hexagram. We prove that a general Desargues configuration in the plane is associated to six conical sextuples via the theorems of Pascal and Kirkman. Moreover, the Galois group associated to this problem is isomorphic to the symmetric group on six letters.

Authors: Barragán Franco , Macías Sergio , Rojas Anahí
Published: May 2021

Let X be a topological space. For any positive integer n, we consider the n-fold symmetric product of X, ℱn(X), consisting of all nonempty subsets of X with at most n points; and for a given function ƒ : X → X, we consider the induced functions ℱn(ƒ): ℱn(X) → ℱn(X). Let M be one of the following classes of functions: exact, transitive, ℤ-transitive, ℤ+-transitive, mixing, weakly mixing, chaotic, turbulent, strongly transitive, totally transitive, orbit-transitive, strictly orbit-transitive, ω-transitive, minimal, I N, T T++, semi-open and irreducible. In this paper we study the relationship between the following statements: ƒ ∈ M and ℱn(ƒ) ∈ M.

Published: May 2021

La calidad de los programas académicos de una institución educativa, medida a través de la aplicación de exámenes estandarizados, constituye una forma de evaluación objetiva del desempeño académico de los estudiantes de educación superior. En este sentido, el objetivo de este trabajo consiste en analizar la relación entre los exámenes de ingreso y egreso desarrollados por el Centro Nacional de Evaluación para la Educación Superior (CENEVAL) y el desempeño académico de una población de 2050 estudiantes de una facultad de negocios de carácter público a través del análisis cuantitativo, descriptivo y correlacional. Los resultados destacan una alta asociación en la metodología de diseño de los exámenes de ingreso y egreso de CENEVAL, en contraposición al bajo poder predictor de los exámenes de ingreso con el promedio general de la carrera. Las contribuciones de este trabajo permiten sentar las bases para la toma de decisiones respecto al uso de exámenes estandarizados como forma de evaluación de los estudiantes.
La formación y profesionalización para la docencia universitaria en México desde la voz de los profesores
Authors: De Agüero -Servín Mercedes , Sánchez-Mendiola Melchor , Martínez-Hernández Ana María del Pilar , Pompa-Mansilla Maura
Published: May 2021

Esta investigación es cualitativa y exploratoria, identifica y comprende las experiencias y creencias docentes acerca de la formación, cómo eligieron ser profesores de la UNAM, de educación media superior y superior; y explora los intereses de formación docente universitaria. Objetivos: ofrecer información fundamental acerca de la formación docente que interesa a los y las profesoras del bachillerato y las licenciaturas; y de las experiencias y necesidades de formación y profesionalización. Método: Se realizaron ocho grupos focales con profesores y profesoras de bachillerato y licenciatura, de las distintas disciplinas, facultades y campus universitarios de la Universidad; de ambos sexos y diversa antigüedad. La información se organizó por categorías de análisis. Resultados: los resultados muestran que la UNAM ofrece principalmente formación docente mediante programas formales, grupales y presenciales. Pocos profesores reconocen formarse o profesionalizarse en contextos informales y grupales como seminarios y congresos; no se reconoce la profesionalización con base en la experiencia, aprender haciendo o por observación. Los programas formales e individuales a distancia son en habilidades prácticas o técnicas.
Investigación educativa y pedagogía de la investigación: crítica de la reproducción del conocimiento científico
Authors: Vega -Torres Daniel Roberto
Published: May 2021

Introducción: El objetivo del artículo es analizar la relación entre pedagogía e investigación como proceso contextualizado en el desarrollo científico y sus características académicas, económicas y políticas que definen su representación actual. Metodología: El texto presenta una metodología cualitativa de tipo descriptivo mediante la técnica de revisión documental. Las categorías que se analizaron son las siguientes: (1) educación e información investigativa, (2) territorio e investigación, (3) diferencias entre investigación educativa y pedagogía de la investigación, desarrollada en dos aspectos, (3a) procesos curriculares, y (3b) didáctica de la investigación, (4) por último, las comunidades de investigación. Resultados del análisis reflexivo: Educar en investigación acarrea problemas que van más allá de comunicar resultados. Las preguntas sobre que se investiga y como se hace se define por la relación territorial del poder y del saber. La flexibilidad en el uso de información tanto por los currículos como por los materiales pedagógicos de investigación, puede llevar a la individualización de procesos formativos. Las formas de sociabilidad y organización de la enseñanza de la investigación deberán tener un espacio definido de proyección política y académica que corresponda con las capacidades de producción de conocimiento autónomo territorialmente. Conclusión: La relación entre pedagogía, didáctica e investigación debe integrar de manera coherente los aspectos de organización y construcción de sociabilidades científicas que tengan como horizonte una participación política.
Saberes digitales de profesores en formación. Evaluación en una escuela mexicana
Authors: Grijalva-Verdugo Abel Antonio , Lara- Rivera José Alejandro
Published: May 2021

En el escenario educativo actual, la adquisición de competencias digitales para construir ciudadanías críticas es una de las premisas del currículum escolar en sus diferentes niveles. En ese sentido, esta investigación indaga el constructo teórico-metodológico saberes digitales, propuesto por Ramírez y Casillas en el año 2014 y que, caracteriza la gestión, uso e interpretación de las TIC en cuatro grandes dimensiones: 1) administración de sistemas digitales, 2) creación y manipulación, 3) socialización y 4) manejo de información. De esta última, parten los hallazgos enmarcados en una evaluación de saberes digitales a profesores en formación o lo que en México se denomina normalistas, y que tiene como finalidad identificar los niveles de literacidad digital, ciudadanía, prácticas digitales legales y pensamiento crítico de los futuros profesores de educación básica. Se trabajó en una institución formadora de formadores (Escuela Normal) ubicada en Baja California, Sur, México. La muestra fue probabilística aleatoria simple compuesta por 119 sujetos divididos por avance en la carrera (universidad alta y universidad baja) ya que, se partió del hipotético de que los conocimientos tecnológicos se relacionan con los años de escolaridad, es decir, a mayores años de estudio saberes digitales más altos. Para el análisis se realizó una factorial exploratoria (KMO y prueba de esfericidad de Bartlett) y t-Student. Los hallazgos dan cuenta de incidencia parcial desde la variable de cruce en algunas de las categorías del estudio.
El Análisis de la experiencia laboral de los estudiantes de maestría
Authors: Rivas-Sepúlveda Edith , Enciso-Ávila María Isabel
Published: May 2021

Los estudiantes acceden a la universidad de formas y por motivos diversos, el propósito de este texto es mostrar la heterogeneidad de los estudiantes de maestría en el área económico-administrativa de la Universidad de Guadalajara (UdeG) en México para las generaciones del 2016 y 2017 con base en su experiencia laboral y motivos de ingreso. Los programas de maestría en su mayoría parten de una idea estandarizada que considera que los itinerarios educativos de sus estudiantes se restringen al ámbito escolar como una continuidad de la licenciatura al posgrado, sin embargo, en el caso estudiado solo lo hace una minoría. Para la gran mayoría de estudiantes de maestría la experiencia laboral es determinante en la elección de los estudios de posgrado, muestra que combinan estudios y trabajo incluso desde antes de su ingreso a la licenciatura. Se encontró que los estudios de maestría se convierten en una estrategia para reorientar o especializar la actividad profesional y que la edad no determina la experiencia laboral. Se construye una tipología de experiencia laboral mediante un método cuantitativo que considera los momentos de trabajo, la relación trabajo y estudios, carrera profesional inicial o avanzada. Dicha tipología permite dividir a los estudiantes en cuatro grupos: expertos, semi-expertos, poco expertos e inexpertos. Siendo los inexpertos quienes asumen un itinerario de continuidad escolar o buscan profesionalizarse, los poco expertos cuya actividad laboral es reducida mientras los semi-expertos y expertos buscan la maestría con el fin de reorientar su actividad profesional, legitimar lo que hacen profesionalmente o como una forma de actualizar sus conocimientos y especializarse.

Relevance. The COVID-19 pandemic is a new challenge facing humanity, which has already caused serious damage to the global economy. In particular, international cooperation has faced somewhat unprecedented challenges. In the post-pandemic era, it is extremely important to study the state of the dairy sector in China in order to find a way to develop cooperation between the People’s Republic of China and the Russian Federation in this field. Research objective. To analyse the state of China’s dairy sector in the post-pandemic period, taking into account the trend of recovery, as well as to identify the priority areas and interaction directions in the dairy sector between China and the Russian Federation. Data and Methods. The research was conducted using the methods of comparative analysis, focusing mainly on quantitative and qualitative indicators. The conditions for the interaction of the dairy sector between China and the Russian Federation were analysed. Results. It is shown that, at present, the Chinese-Russian interaction in the dairy sector includes four aspects: trade in dairy products, experience exchange, investment cooperation and interaction at the governmental level. Trade in dairy products and the exchange of experience and technologies in the dairy sector are developing steadily, supported by increased interaction at the state level. Conclusions. The Chinese-Russian cooperation in the dairy sector is experiencing some difficulties; however, the common interest of both countries in dairy production and the strong support of both governments ensure excellent prospects for achieving mutual benefits and high performance.
LIÇÕES DE PROFESSORAS ALFABETIZADORAS “EXPERIENTES” ÀS PROFESSORAS ALFABETIZADORAS “INICIANTES”: CONTRIBUIÇÕES PARA O DESENVOLVIMENTO PROFISSIONAL DOCENTE
Authors: Bruns Juliana Pedroso , Rausch Rita Buzzi
Published: May 2021

A presente pesquisa teve por objetivo compreender as lições de professoras alfabetizadoras “experientes” às professoras alfabetizadoras “iniciantes” e suas contribuições ao desenvolvimento profissional docente. A opção por professoras alfabetizadoras experientes, justifica-se pela trajetória já vivenciada por seis professoras no exercício de sua profissão, já que atuavam há mais de quinze anos na Rede Municipal de Ensino de Brusque (SC) como alfabetizadoras. Como referencial teórico elegeu-se as contribuições de Marcelo García (1999, 2009), Vaillant e Marcelo (2012, 2015, 2017), Imbernón (2010, 2011), e Nóvoa (1992, 1999, 2002, 2009, 2010),  Mortatti (2000, 2008), Soares (2004, 2011, 2016), Ferreiro e Teberosky (1999) para  dialogar  com  as  narrativas  das  professoras  participantes. A pesquisa é de abordagem qualitativa e biográfica denominada “história de vida”, e a análise dos dados ocorreu mediante a análise textual discursiva. Os resultados evidenciaram que as contribuições ao desenvolvimento profissional docente perpassam a formação para alfabetizar; conhecimentos pedagógicos; conhecimentos específicos da alfabetização; atitudes docentes e laços afetivos. Esta pesquisa pretende beneficiar especialmente professoras alfabetizadoras, pois os resultados desta investigação poderão amenizar os dilemas enfrentados por professoras alfabetizadoras iniciantes, bem como, valorizar os saberes construídos por professoras experientes em suas trajetórias profissionais. Este estudo poderá trazer ainda benefícios indiretos ao processo de alfabetização de crianças, pois ao contribuir com uma nova compreensão acerca das etapas de desenvolvimento profissional docente, poderá favorecer percursos formativos às professoras alfabetizadores em diferentes fases da vida profissional.
