ABSTRACT

Social solidarity is the togetherness of individuals or groups that arise from moral feelings and shared beliefs that are reinforced by shared emotional experiences. Durkheim in Maliki said, there are two social solidarity namely mechanical solidarity and organic solidarity. Mechanical solidarity is an individual's awareness in carrying out social life based on the foundation of identity among its members. Whereas organic solidarity is an awareness developed on the basis of social cohesion through different solidarity models within the class of its members.

This research uses descriptive qualitative method, research location in the city of Kupang. Data collection is done through library research, observation, in-depth interviews, and documentation techniques. The informants in this study were students of the State Senior High School in Kupang. Data analysis techniques used in this study were by means of data collection, data reduction, data presentation and drawing conclusions.

The results showed that organic social solidarity was quite prominent in students. In the process of student social interaction, organic solidarity is more prominent. This is seen through one of the student activities in the learning process such as the division of study groups. The behavior of choosing friends according to liking, emotional closeness is very prominent. While the division of student roles is going well, but individuality or competition in groups and competition with other groups of students is inevitable.

Feeling of Safety among Residents in Metropolitan Lagos, Nigeria
Authors: ADEJOH PIUS
Published: January 2020

Abstract

This study examines the social factors that underpin the feeling of safety among residents   in metropolitan Lagos. The paper is anchored on the instrumental and expressive theories of fear of crime and feeling of safety. It utilized quantitative data that were generated from 1,107 community members aged 18 who were drawn from four Local Government Areas of Lagos state. The study found a strong positive association between sex, employment, ethnicity, income; perceived neighbourhood crime level, experience of victimization, neighbourhood disorderliness and feeling of safety.It was recommended that relevant agencies of government-the police especially, must strive harder to improve citizens’ feeling of safety, because of its profound implications for the flourishing of democracy, economic development, social capital, associational life and the quality of life.
Suicide as a social dilemma: Evidence from Pakistan
Authors: Ahmed Zubair , Bhati Ilyas , Kausar Rizwana
Published: January 2020

Abstract

Suicide is one of the major causes of death around the globe. It has become sensitive and imperative anthropological, psychological and public health issue which need to be tackled. The present paper provides an overview of the growing literature on suicide or more commonly known as “attempted suicide or completed suicide”. Suicidal attempts (and /or completed suicides) are increasing in urban and rural areas of Pakistan such as Karachi, Ghizer, and Hunza. The exact reasons are indefinite. This paper focuses on existing literature 1) the concept of suicide; 2) analyzes the existing consensus/figures of suicide in Pakistan; 3) analyzes the main determinants; 4) risk factors of suicide; 5) analyzes the modes of suicide discussed in the existing literature on suicides in Pakistan; and 6) offers literature gap and limitations of the evidences. It has revealed that the exact factors of socio-cultural and economical determinants of suicide in rural and urban areas were investigated paradoxically due to lack of meticulous quantitative and qualitative research. Majority studies focused on suicide in women but not even a single study focused on underlying factors of suicide in men. Further methodical studies are suggested at the community level.

From Symbolism to Realism. Physical and Imaginary Video Game Spaces in Historical Aspects
Authors: Tołkaczewski Filip
Published: January 2020

Physical and imaginary video game spaces have been constantly evolving, starting from dark indefinable space to ultimately become an incredibly realistic world. This paper aims at illustrating how physical and imaginary spaces have evolved. The older games are, the more indefinable and iconic their physical spaces become. In more modern games physical spaces are being more and more developed. It is now possible to move the place of action from the heights of a symbolic universe to a particular land located in a specific timeline, which made it possible to create realistic settings and characters in a life-like manner.

Uncanny Valley in Video Games: An Overview
Authors: Ratajczyk Dawid
Published: January 2020

The uncanny valley is an idea proposed by Masahiro Mori (1970) regarding negative emotions present in contacts with almost humanlike characters. In the beginning, it was considered only in the context of humanoid robots, but this context was broadened by the development of highly realistic animations and video games. Particularly evident are players’ interests in the uncanny valley. Recently there have been a growing number of reports from empirical studies regarding participants’ perception of highly realistic characters. In the paper, a review of publications concerning the uncanny valley hypothesis in video games is presented, as are deliberations about the impact of the uncanny valley on the game industry. According to the results, there is a need to recognise which attributes of virtual characters cause the uncanny valley effect.

Intelligibility in Chinese English Spoken in Central China
Authors: Zhou Weijing , Deterding David , Nolan Francis
Published: January 2020

It is widely accepted nowadays that intelligibility is the essential goal for most learners of English, and it is not necessary for them to mimic all aspects of native-speaker English in order to achieve a high level of intelligibility. However, the features that are needed in order to make oneself easily understood by listeners from elsewhere remain controversial. The current research focuses on thirteen five-minute recordings of conversations between young speakers of English in central China and an interviewer from Britain, in order to determine which features of their speech gave rise to misunderstandings. It was found that, in the 18 tokens of misunderstanding identified, 4 resulted from lexical semantics (22%), 3 from Chinese place names (17%), 3 from grammar (17%) , and 11 from pronunciation (61%) (with some tokens cross-classified). The most common phonological factors giving rise to loss of intelligibility were omission of syllables and simplification of word-initial consonant clusters.
NEAT1 promotes LPS-induced inflammatory injury in macrophages by regulating miR-17-5p/TLR4
Authors: Li Yanhui , Guo Wei , Cai Yeping
Published: January 2020

Background

The inflammatory response of macrophages is responsible for sepsis. Long noncoding RNA nuclear enriched abundant transcript 1 (NEAT1) has been reported to be involved in sepsis development. However, its underlying mechanism remains largely unclear. This study aims to investigate the effect of NEAT1 on inflammatory response of macrophages and explore the regulatory network of NEAT1/microRNA-17-5p (miR-17-5p)/Toll-like receptor 4 (TLR4).

Methods

The serum samples of 68 sepsis patients and 32 heathy controls were collected. THP-1 macrophages were treated with lipopolysaccharide (LPS) to induce inflammatory injury model of sepsis. The expressions of NEAT1, miR-17-5p and TLR4 were measured by quantitative real-time polymerase chain reaction or western blot. The inflammatory response was investigated by levels of inflammatory cytokines, tumor necrosis factor-alpha (TNF-ɑ), interleukin-1beta (IL-1β) and IL-6 as well as nitric oxide (NO) production. The interaction among NEAT1, miR-17-5p and TLR4 were investigated by bioinformatics analysis, luciferase reporter assay and RNA pull-down.

Results

NEAT1 expression was enhanced in patient serum and associated with severity of sepsis. Knockdown of NEAT1 inhibited levels of TNF-ɑ, IL-1β, IL-6 and NO release in LPS-treated macrophages. miR-17-5p is bound to NEAT1 and its abrogation reversed NEAT1 knockdown-mediated inhibition of inflammatory response in LPS-treated macrophages. Overexpression of miR-17-5p weakened LPS-induced inflammatory response. TLR4 as a target of miR-17-5p was regulated by NEAT1 and miR-17-5p. TLR4 res-to ration alleviated silencing NEAT1-induced inflammatory suppression.

Conclusion

Silence of NEAT1 suppressed LPS-induced inflammatory response of macrophages by mediating miR-17-5p and TLR4, indicating that NEAT1 might be a promising target for sepsis treatment.
Laboratory Investigation into the Effect of Particle Sizes on Shear Wave Parameters Using Bender Elements Test Results
Authors: Sharifi Abolhasan , Sharifipour Mohammad , Rizvandy Amir
Published: January 2020

Evaluating the influences of soil particle size on the dynamic behavior of soils during wave propagation has been an important issue in geotechnical engineering. Heretofore, the effects of particle size on shear wave velocities in soils have been examined using various experimental techniques. Most research in this regard so far have been carried out over a limited range of particle sizes, and the results have indicated contrasting effects of particle size on shear wave velocity (Vs). However, there has not been a comprehensive and unambiguous outcome describing the influences of particle size on Vs in soils. This research aims to experimentally investigate the effects of a wider range of particle sizes on Vs, wave shape, and frequency content of the shear waves transmitted in soil specimens. To this aim, a bender element apparatus embedded in a triaxial cell were used to minutely measure shear wave parameters of ten groups of local dry sandy soils, R1 (d50 = 0.225 mm) to R10 (d50 = 7.14 mm) samples. Moreover, dry tamping methods were employed to provide comparable samples at a similar initial void ratio of 0.8. Various amounts of frequency (5–12 kHz) and various confining pressures (50–500 kPa) were conducted on the identically prepared clean sand samples. Based on the results, it was observed that, for samples with mean particle sizes between 0.225 mm (R1) and 1.290 mm (R6), the Vs increased with the particle diameter, but for samples with mean particle sizes between 1.290 mm (R6) and 7.140 mm (R10), an increment in the particle diameter caused the Vs to decrease. It can be inferred that particle size influences the shape of the received signals such that the frequency content of the received signals, in both fine- and coarse-grained soils, are quite similar; however, medium-sized soils have a higher frequency content and a higher Vs, as well.
Optogenetic Activation of the Basolateral Amygdala Promotes Both Appetitive Conditioning and the Instrumental Pursuit of Reward Cues
Authors: Servonnet Alice , Hernandez Giovanni , El Hage Cynthia , Rompré Pierre-Paul , Samaha Anne-Noël
Published: January 2020

Reward-associated stimuli can both evoke conditioned responses and acquire reinforcing properties in their own right, becoming avidly pursued. Such conditioned stimuli (CS) can guide reward-seeking behavior in adaptive (e.g., locating food) and maladaptive (e.g., binge eating) ways. The basolateral amygdala (BLA) regulates conditioned responses evoked by appetitive CS, but less is known about how the BLA contributes to the instrumental pursuit of CS. Here we studied the influence of BLA neuron activity on both behavioral effects. Water-restricted male rats learned to associate a light-tone cue (CS) with water delivery into a port. During these Pavlovian conditioning sessions, we paired CS presentations with photo-stimulation of channelrhodopsin-2 (ChR2)-expressing BLA neurons. BLA photo-stimulation potentiated CS-evoked port entries during conditioning, indicating enhanced conditioned approach and appetitive conditioning. Next, new rats received Pavlovian conditioning without photo-stimulation. These rats then received instrumental conditioning sessions where they could press an inactive lever or an active lever that produced CS presentation, without water delivery. Rats pressed more on the active versus inactive lever, and pairing CS presentation with BLA-ChR2 photo-stimulation intensified responding for the CS. This suggests that BLA-ChR2 photo-stimulation enhanced CS incentive value. In a separate experiment, rats did not reliably self-administer BLA-ChR2 stimulations, suggesting that BLA neurons do not carry a primary reward signal. Last, intra-BLA infusions ofd-amphetamine also intensified lever-pressing for the CS. The findings suggest that BLA-mediated activity facilitates CS control over behavior by enhancing both appetitive Pavlovian conditioning and instrumental pursuit of CS.

SIGNIFICANCE STATEMENTCues paired with rewards can guide animals to valuable resources such as food. Cues can also promote dysfunctional reward-seeking behavior, as in overeating. Reward-paired cues influence reward seeking through two major mechanisms. First, reward-paired cues evoke conditioned anticipatory behaviors to prepare for impending rewards. Second, reward-paired cues are powerful motivators and they can evoke pursuit in their own right. Here we show that increasing neural activity in the basolateral amygdala enhances both conditioned anticipatory behaviors and pursuit of reward-paired cues. The basolateral amygdala therefore facilitates cue-induced control over behavior by both increasing anticipation of impending rewards and making reward cues more attractive.
Acidovorax citrulli is sensitive to elevated temperatures during early stages of watermelon seed germination
Authors: Zhao Mei , Walcott Ron
Published: January 2020

Bacterial fruit blotch (BFB), caused by Acidovorax citrulli, is a seed-transmitted disease of cucurbit crop species. During seed-to-seedling transmission of BFB, A. citrulli initially grows as a saprophyte on germinating seeds and subsequently switches to a pathogenic
mode. We investigated the effect of temperature on A. citrulli colonisation of germinating watermelon seeds. Seeds were vacuum-infiltrated with 106 CFU/ml A. citrulli, germinated at 28°C and 100% relative humidity, and transferred to 40°C at different times.
Mean BFB incidence was significantly lower for seeds that were sown at 28°C and transferred to 40°C three days after sowing (DAS), compared with seeds incubated constantly at 28°C. Seeds showed reduced mean BFB transmission percentages when transferred from 28 to 40°C at 3
DAS, regardless of initial A. citrulli concentration. The effect of increased temperature on BFB seedling transmission was reversible regardless of the initial A. citrulli inoculum concentration. Furthermore, the A. citrulli population on germinating watermelon seedlings
that were transferred from 28 to 40°C at 3 DAS was significantly lower than seedlings maintained at 28°C. We conclude that A. citrulli cells associated with germinating watermelon seeds are more sensitive to elevated temperature during the first 3 DAS relative to the later
days.

Authors: Kopecka-Piech Katarzyna
Published: January 2020

The purpose of this article is to provide a broader characterisation of the media convergence strategy applied by producers of the Polish commercial television station (TVN) series 39 and a half (39 i pół). In order to examine the convergence strategies of production, distribution, promotion and media usage, this paper analyzes metaphors of landscape, terrain, map and simulacrum. Moreover the concept of convergent (inter)text is proposed. In the case study of 39 and a half the author examines three main strategies implemented by the creators: the promotional virtualisation of reality, making virtual reality more real, and multiplied fiction. Transmedial and synergetic brands illustrate the hybridisation of the convergent and integrated media landscape.

ASPECTOS AMBIENTAIS DAS ÁREAS SUSCEPTÍVEIS À DESERTIFICAÇÃO E CARACTERÍSTICAS SOCIOAMBIENTAIS DO NÚCLEO DE DESERTIFICAÇÃO DO SERIDÓ DO RIO GRANDE DO NORTE (RN) E PARAÍBA (PB)
Authors: Lucena Marcelo Silva de
Published: January 2020

Apesar da relevância, as discussões e a disseminação de informações, a execução de medidas para o enfretamento da desertificação praticamente não têm sido executadas. Neste sentido, este trabalho visa apresentar uma síntese de informações sobre os aspectos ambientais das áreas susceptíveis à desertificação no Semiárido brasileiro e apresentar as características socioambientais relacionadas mais diretamente com a desertificação no Seridó do Rio Grande do Norte e Paraíba. Para tal, foi realizada pesquisa onde se efetuou consulta a livros, documentos institucionais, periódicos especializados, artigos científicos e acesso a bancos de dados, por meio de expressões em português que dissessem respeito à desertificação, áreas susceptíveis à desertificação, núcleo de desertificação e núcleo de desertificação do Seridó. Constatou-se que as ASD, no Brasil, ocupam 1.340.000 km2, sendo a região semiárida sua principal  integrante. Nas ASD, predominam índices pluviométricos abaixo de 800 mm, com alta evapotranspiração potencial. Os solos, com longa ocupação humana e sensibilidade à erosão de moderada a alta, apresentam os seguintes níveis de degradação: 40,80% “moderado”; 27,68% “grave” e 5,86% “muito grave”. A Caatinga é bioma predominante, onde 46,4% do território apresentam-se antropizados. No Seridó RN/PB, as implicações das atividades econômicas predominantes, caracterizadas por intensa extração de lenha, para utilização na indústria ceramista e em pequenas indústrias urbanas, e pela utilização crescente das terras, antes voltadas à agricultura, para a produção pecuária, estão forjando um quadro de degradação ambiental, requerendo, em função de suas características naturais, um modelo de aproveitamento econômico adequado às condições semiáridas.

Published: January 2020

O docente que possui qualquer formação inicial que não seja a licenciatura necessita de uma complementação pedagógica para atuar na docência. Para isso, nos últimos anos os IFs vêm buscando implantar cursos de formação pedagógica, haja vista habilitar e capacitar os docentes que ainda não possuem tal formação. Nesse estudo objetivou-se avaliar a importância da formação pedagógica do tecnólogo para atuação como docente no Instituto Federal do Amapá – Campus Macapá. A pesquisa de campo foi realizada durante o ano letivo de 2017, sendo necessárias as seguintes etapas: análise documental (perfil para participar da pesquisa), aplicação dos questionários a todos os professores com a formação de tecnólogo, totalizando doze professores, sendo que apenas 9 responderam o questionário. Por meio do questionário foi possível traçar o perfil do docente, no que se refere a sexo, faixa etária, regime de trabalho, formação, experiência profissional (no magistério e em outras atividades), as especificidades e os desafios da prática docente na Educação Profissinal e Tecnólogica (EPT), conforme em estudos realizado por Silva (2003) e Pena (2014) ).  Todavia, todo e qualquer docente deve atender ao processo de ensino / aprendizagem, sendo que antes devem ter conhecimento das diversidades e modalidades de ensino, situações e contexto social em que os discentes vivem, de modo que atendam aos anseios da sociedade como um todo.  Os docentes que participaram dessa pesquisa salientaram que os cursos de formação continuada contribuem consideravelmente para a formação do tecnólogo, tendo em vista que é de suma importância para prática docente no sentido de aprimoramento de métodos de avaliações, aulas inovadoras, construção de provas contextualizadas, conhecer novas perspectivas sobre o ensino e regulamentações voltadas para atuação docente.  Na dinâmica ensino / aprendizagem os docentes necessitam de capacitação para atender de forma satisfatória as diferentes modalidades de ensino e diversidade de cursos ofertados pela Instituição.

Enemy Construction in the Declaration of War against Japanese Empire
Authors: Asmaradhani Ahmad Idris
Published: January 2020

This paper seeks to identify and describe the linguistic priming work that President Roosevelt employed in overcoming isolationism in the United States. In his Declaration of War against the Japanese Empire, President Roosevelt asked the American people to trust him with the American forces and American determination using the strategy of enemy construction. Making courageous statements packed in political discourse, he framed the people’s minds into a state of patriotic country defenders and that the Japanese Empire was an enemy and a real danger to the life of the country. His statements are a formulation that America is ready for war with an assurance of a near-absolute victory. Applying the method and theories of Critical Discourse Analysis centered around the framework of “ideological square” and “socio-cognitive approach” for building in-group and out-group as one major aspect of CDA supported with other linguistic theories, this paper aimed at analyzing and describing such linguistic priming to get out of the country isolationist slumber. Based on the results of the analysis and discussion, it is argued that in terms of CDA and socio-cognitive as well as other linguistic theories the enemy construction was inter-textually successful in winning the American people’s consent.
Integrating Islamic Values into ESP Reading Material

Published: January 2020

This present research is aiming at developing suitable instructional reading material for the students of Islamic Education Department. The procedure employed in this study was R&D model proposed by Dick and Carey, namely, need analysis, developing reading materials, expert validation, revising the materials, trying out the materials, and revising the materials. The result shows that reading materials must be developed by incorporating major content subject, namely Islamic studies, list of vocabulary, grammar review, and reading comprehension exercises. Furthermore, after being tried-out, it shows the applicability of the developed materials in helping the students to accomplish the mastery of reading skills and improve their learning motivation. In spite of the strength of the material developed, it is still tried-out in the small scale; therefore, the materials were still possible to be revised.

Five strategies of microbially induced calcite precipitation (MICP) are suggested to improve the uniformity of treatment and enhance the erosional/hydraulic response of internally unstable and poorly graded soils. The treatment consisted of the injection of a bacterial suspension and a cementation solution. The volume of the injected bacterial suspension varied from 0·3 to one pore volume, while the concentration of the cementation solution (urea/calcium chloride (CaCl2)) varied from 0·35 to 0·75 M. The biotreatment of sand columns (ϕ = 160 mm and h = 100 mm) was conducted in either one, two or three stages, with or without a low-salinity fixation solution. The biotreated specimens were then submitted to an erosion test, and the results show that alternating injection of reagents in three stages enhances the uniformity of biomineralisation, as the hydraulic conductivity is constant from the top to the bottom of the specimens. This protocol also prevents internal erosion as the critical hydraulic gradient (i cr) is equal to 10 and the cumulative fine loss (M e) does not exceed 63 g/m2. Finally, the use of a fixation solution prevents any clogging near the injection point and stimulates the bacterial transport in the soil.
Confidence, Financial Literacy and Investment in Risky Assets: Evidence from the Survey of Consumer Finances

We employ recent Survey of Consumer Finances (SCF) microdata from the US to analyze the impacts of confidence in one’s own financial knowledge, confidence in the economy, and objective financial literacy on investment in risky financial assets (equity and bonds) on both the extensive and intensive margins. Controlling for a rich set of covariates including risk aversion, we find that objective financial literacy is positively related to investment in risky assets as well as debt securities. Moreover, confidence in own financial skills additionally increases the probability of holding risky assets and bonds. While these relationships are rather robust for the extensive margin, they break down with regard to the conditional share of financial wealth in risky assets of those who actually hold them. The relevance of financial literacy as well as confidence varies considerably with the distribution of wealth as well as across several socio-economic dimensions such as age, education and race.
Consumption Heterogeneity: Micro Drivers and Macro Implications
Authors: Crawley Edmund , Kuchler Andreas
Published: January 2020

This paper explores the microfoundations of consumption models and quantifies the macro implications of consumption heterogeneity. We propose a new empirical method to estimate the response of consumption to permanent and transitory income shocks for different groups of households. We then apply this method to administrative data from Denmark. The large sample size, along with detailed household balance sheet information, allows us to finely divide the population along relevant dimensions. We find that households that stand to lose from an interest rate hike are significantly more responsive to income shocks than those that stand to gain. Following a 1-percentage-point interest rate increase, we estimate that consumption growth decreases by a 1/4 percentage point through this interest rate exposure channel alone, making this channel substantially larger than the intertemporal substitution channel that is at the core of representative agent New Keynesian models.

Representación del significado léxico de tarea escolar: la visión de los estudiantes
Authors: Ruiz Vega Jaime , Santiago Galvis Alvaro William , Castillo Perilla Myriam Cecilia
Published: January 2020

Este artículo presenta otra parte de los resultados del proyecto de investigación Concepciones de los estudiantes de educación básica secundaria y media de Bogotá sobre la entidad léxica tarea escolar (DLE-427-16), sustentado en los planteamientos de la Semántica de los Posibles Argumentativos (spa); orientación teórica que centra su interés en el estudio del significado léxico y su relación con los valores, así como con las representaciones, individuales y sociales, que las formas léxicas vehiculan. Esto se sustenta en el planteamiento de que los hablantes de una lengua, en el uso discursivo, ofrecen una axiologización discursiva del mundo que se hace evidente en el nivel léxico. Para efectos de establecer dicha axiologización se recurre, metodológicamente, al análisis de corpus léxicos obtenidos a partir de la aplicación de cuestionarios que permiten tener una muestra de la producción discursiva de los hablantes, en este caso, estudiantes de educación básica secundaria y media de Bogotá. En este texto se ofrece el análisis de los datos obtenidos, fundamentalmente en lo que respecta a los encadenamientos argumentativos derivados del significado léxico, así como de los discursos de los estudiantes que reclaman la continuidad de las tareas como una actividad escolar necesaria y útil; de esta forma, el texto ofrece las razones que la población en cuestión esgrimió para que la tarea escolar se mantenga como parte del proceso de formación de los individuos.
Factores que influyen en el aprendizaje del inglés de los bachilleres de Pasto, Colombia

En la literatura de la Adquisición de una Segunda Lengua (ASL), campo desarrollado en contextos donde la lengua se utiliza como medio de comunicación, y de Aprendizaje de una Lengua Extranjera (ALE), subcampo en el que la lengua se utiliza fundamentalmente como asignatura de estudio en las aulas de clase, se han identificado varios factores que contribuyen a su aprendizaje. Para avanzar en esta línea de investigación sobre factores que inciden en el aprendizaje de las lenguas, se diseñó un estudio sustentado en un paradigma empírico-analítico y en un método descriptivo, cuyo objetivo general fue analizar los factores internos y externos que tienen una mayor influencia sobre el nivel de aprendizaje del inglés como lengua extranjera (AILE), según las percepciones de los estudiantes y profesores de bachillerato de Pasto. Los datos fueron recogidos por medio de dos cuestionarios, aplicados a 113 estudiantes recién egresados de bachillerato y a 25 profesores. Los resultados indicaron que según las percepciones de los estudiantes y de los profesores, tanto factores externos como internos contribuyen positivamente en el AILE. Sin embargo, los factores externos que parecen contribuir más se relacionan, por una parte, con 1) el ambiente del aprendizaje en el aula, 2) el currículo institucional, 3) la preparación profesional de los profesores, 4) el papel de la comunidad local y 5) el papel de las políticas nacionales. Por otra parte, mientras los profesores resaltaron los factores internos de carácter cognitivo y afectivo, los estudiantes destacaron los factores cognitivos y lingüísticos.

Published: January 2020

En este artículo presentamos resultados de un estudio que tuvo como objetivo caracterizar la construcción del Conocimiento Profesional del Profesor de Ciencias en los espacios académicos de Práctica Pedagógica I y Práctica Pedagógica II, desarrollada al interior de la Licenciatura en Ciencias Naturales: Física, Química, Biología de la Universidad Surcolombiana (Neiva, Colombia). Partimos de un enfoque cualitativo prospectivo longitudinal, haciendo uso del método de análisis de contenido a través del software Atlas. Ti 7.0. Como instrumentos para la recolección de información, empleamos la observación participante y el análisis documental realizado sobre las producciones de los futuros docentes. Sistematizamos la acción de dos futuros profesores durante 3 meses en el primer semestre del 2015. Para el análisis tuvimos en cuenta componentes del Conocimiento Didáctico del Contenido, encontrando en los resultados una movilización actitudinal y contextual por parte de los futuros docentes frente al desarrollo de sus prácticas profesionales, al igual, evidenciamos una marcada postura reflexiva y crítica sobre la enseñanza-aprendizaje de las ciencias, lo que les permitió una mejor autorregulación en los procesos de configuración de un Conocimiento del Profesor específico.
Evolución biológica y reflexión metacientífica. Aportes para la formación docente del profesorado de ciencias
Authors: Astudillo Carola , Rivarosa Alcira , Adúriz-Bravo Agustín
Published: January 2020

Este artículo de investigación fundamenta la integración de la reflexión metacientífica en la formación disciplinar y didáctica del profesorado de ciencias y su contextualización en torno a nociones estructurantes de la Biología. Más concretamente, las reflexiones se centran en la noción de evolución biológica, seleccionada por su alto poder explicativo y vertebrador de la disciplina, así como por su fuerte impregnación cultural. Además, y con la intención de acercar contenidos potenciales para la mencionada integración, se presentan los resultados de una serie de entrevistas a biólogos, profesores de biología, didactas, filósofos y divulgadores científicos. Los especialistas, desde sus disciplinas de referencia, aportan a la caracterización epistémica, cultural y cognitiva de la noción. Esta caracterización, contextualizada en la discusión sobre los íconos populares con que se refiere a la noción de evolución y la figura de Charles Darwin, refiere principalmente a la naturaleza del trabajo científico, la noción de verdad, los condicionamientos históricos, culturales y éticos de la producción científica, los obstáculos epistemológicos específicos de la construcción del modelo evolutivo, la naturaleza de la controversia ciencia-religión, entre otros aspectos. Finalmente, y a modo de conclusiones, se ofrecen algunas reflexiones sobre los aportes de esta caracterización para pensar la enseñanza en la formación docente, recuperando de manera crítica e integrada algunos tópicos centrales de reflexión metacientífica.

Published: January 2020

Con el fin de contribuir a las discusiones que abordan los equipos pedagógicos al iniciar los procesos de virtualización y diseño de situaciones educativas mediadas por las tecnologías de la información y la comunicación, presentamos algunas conclusiones a las que hemos llegado en el grupo de investigaciónEpisteme, luego de dirigir cursos y tesis de grado en la especialización y maestría en Tecnologías de la Información Aplicadas a la Educación del Departamento de Tecnología de la Universidad Pedagógica Nacional (Colombia). Estas reflexiones han dilucidado cómo se diseña la situación educativa para ambientes virtuales de aprendizaje (ava) desde los modelamientos cognitivo, tecnológico, comunicativo y pedagógico, que se explican en la primera parte del artículo. Posteriormente, como ejemplo, planteamos una situación educativa hipotética e ilustramos la manera en que se toman estas decisiones de diseño. No se aborda la evaluación, que será objeto de un artículo posterior.
