Published: October 2019

Este trabalho apresenta o desenho e as respectivas reflexões a respeito de uma experiência didática de elaboração de uma oficina de caráter investigativo realizada com alunos das séries do ensino médio de uma escola pública no interior do estado de São Paulo. A oficina “Investigações em Química”, proposta e executada pelos próprios professores de Química, teve por objetivo proporcionar aos alunos vivências com a experimentação investigativa, o fazer e o agir científico e a argumentação, na busca pelo desenvolvimento conceitual, atitudinal, procedimental e uma formação crítica do aluno. Estruturada em três momentos, contou com a participação de dez alunos que desenvolveram suas atividades seguindo as etapas do método investigativo, da elaboração de hipóteses às considerações finais, para desvendar um crime. Embora com poucas experiências em investigações, os estudantes alcançaram satisfatoriamente os objetivos, principalmente ao pensar-se no desenvolvimento dos conceitos científicos, da leitura e da escrita, da argumentação e suas próprias aprendizagens, uma vez que os estudantes foram convidados a refletir sobre o impacto de atividades experimentais em sua formação.

Authors: Reyes Moreno J.A. , Pérez Corona F.Y. , Árcega Santillán I. , Ortíz Hernández L.E.
Published: October 2019

La zona de estudio se ubica entre las provincias fisiográficas de la sierra madre oriental y la faja volcánica transmexicana. Geológicamente, corresponde a la plataforma valles-San Luis Potosí, formada durante el cretácico en la porción este y centro de México. De manera específica, el área de estudio se sitúa en la caldera panales (CP) con un diámetro aproximado de 9 kilómetros, exponiendo diversos domos, diques dacíticos y un intrusivo de composición diorítica que provocó metamorfismo de contacto en la caliza encajonante. El objetivo del presente trabajo es obtener un modelo geológico-geofísico del subsuelo de la CP.

Para el estudio e interpretación del subsuelo se combinaron métodos potenciales (gravimetría y magnetometría) e imágenes Sentinel2, a los cuales se les aplicaron diferentes algoritmos matemáticos. El análisis indica que existe una correlación entre los lineamientos obtenidos de los métodos potenciales y la percepción remota con las diferentes fallas, fracturas y contactos geológicos, de igual manera con la modelación 2D se obtuvo la geometría relativa de la CP. Los resultados obtenidos corroboran que la estructura semicircular de Panales corresponde a una caldera, así como su correlación con los diferentes eventos tectónicos y volcánicos.

Reflexões teóricas sobre perspectivas críticas na Educação a distância
Authors: Vieira da Silva Karin , Peixoto João , Sasaki Vasques Pacheco Anderson
Published: October 2019

A educação a distância é uma temática que desperta grandes discussões e controvérsias, especialmente sobre os seus limites e possibilidades. O presente artigo pretende apresentar e refletir sobre as principais críticas relacionadas à educação a distância na literatura corrente. Para tanto, resgatou-se, na literatura, temáticas recorrentes, que incluem o debate sobre a utilização das tecnologias de informação e de comunicação (TICs) na educação, a problemática da interação mediada por aparatos tecnológicos, o processo de mercantilização da educação, e, por fim, reflexões sobre a promoção acrítica do potencial da EaD em promover a autonomia, emancipação e democratização em âmbito escolar. Desta discussão, verifica-se que tais problemáticas não são exclusivas da modalidade a distância, mas que parecem ganhar maior dimensão quando discutidas em seu âmbito. Assim como um dos grandes equívocos nesse campo refere-se à crença sobre o potencial inerente da EaD em solucionar as vicissitudes do modelo tradicional. Por fim, destaca-se que o arcabouço científico disponível não permite conclusões detalhadas sobre assunto e precisa ser melhor explorado enquanto prática educacional e impacto social.
La mirada aérea de la flâneuse: el paisaje vertical en Papeles falsos y “Swings of Harlem” de Valeria Luiselli
Authors: Oliver María Paz
Published: October 2019

Este artículo está enfocado en la representación de la mirada aérea y el paisaje vertical en dos textos de la escritora mexicana Valeria Luiselli. Ya sea a través de los mapas o la experiencia de viajar en avión, la perspectiva aérea evidenciaría la dificultad de representar un lugar y la posibilidad de crear un territorio ilusorio que complementa la dimensión horizontal de sus caminatas urbanas. La verticalidad del paisaje representado en los textos confronta la cotidianidad del paseo con una imagen abstracta mediada por la cultura visual de la vista aérea y el turismo. En la distancia reflexiva de la mirada vertical, la obra de Luiselli retoma la capacidad contemplativa y ensoñadora propia del desplazamiento a pie.

Using Reflexive Lifelines in Biographical Interviews to aid the Collection, Visualization and Analysis of Resilience
Authors: Gray Jane , Dagg Jennifer
Published: October 2019

This article demonstrates the use of a reflexive lifeline instrument within a study oriented towards documenting and explaining resilience from a sociological perspective. Informed by both life course and biographical perspectives, our research design comprised two interviews incorporating recursive co-construction of the participant’s lifeline. We aimed to meet three objectives with this method: (1) to collect accurate retrospective data about the timing of lives; (2) to garner biographical data that allowed us to explore lives as wholes; and (3) to elicit participant reflexivity on turning points associated with resilience. Our approach was distinctive in its explicit use of the lifeline both as a means to bring life stories into dialogue with life histories, and as a dynamic prompt to engage participants in the reflexive co-construction of turning points as fateful moments. We illustrate our approach through a case presentation and analysis of the reflexive lifelines co-constructed with two men who participated in our study. We also show how the reflexive lifeline interview generated opportunities for participant-led researcher reflexivity.
Introducing the Target Language Culture to EFL Learners to Enhance Sociocultural Competence
Authors: KHOUNI OUARDA , Alraimi Looloo Mohammed
Published: October 2019

This research attempted to investigate the effect that teaching English language culture has on Algerian EFL (English as a Foreign Language) learners' sociocultural competence. It also aimed at showing that having no exposure to English language culture alongside learning the English language itself will affect learners' understanding and production of the language. In this light, the study attempts to answer the following questions: to what extent is the culture of the English language present in the lessons of English language that are introduced to secondary school students? What cultural background do secondary school students have about the English language? And if they do have any cultural background, what is the source of that background and whether culture teaching enhances EFL learners' socio-cultural competence? We hypothesised that teaching culture to Algerian EFL learners will increase their sociocultural competence and improve their understanding of the language. This hypothesis was tested through conducting a quasi-experimental study with a group of eighteen students from Habba Abd El-Madjid Secondary School in El-Meghaier, El-Oued (Algeria) The final results revealed a remarkable improvement among the majority of students concerning their sociocultural competence and their perception and understanding of authentic English language. Therefore, it is recommended that the element of culture should be integrated into English language curricula of Algerian schools and that, if done, it will take students' level one step further towards a better acquisition of English language.
Involve Me, and I Learn: Preparing English Language Intensive Program Students to the Demands of their Academic Programs
Authors: Alshahrani Ali Ayed , Mohammad Rashid Mahmood
Published: October 2019

This study aims to identify Saudi English as a Foreign Language (EFL) students' perspectives towards using the English language in their studies. The study explores students self-confident and its association with students' actual performance in English course in their different academic programs. A multimodal methodology was used to fulfill the research purpose and answer the research questions. A 25-item survey questionnaire and final examination grades were used to collect data. Two hundred forty-one students agreed to participate in the study. They completed the questionnaire and agreed to release their final grades to be a part of the collected data. The data were coded and analyzed by SPSS software. The findings indicated a significant difference in students' performance in English courses between participants' academic programs on the one hand. Students' self-confidence in their English language skills, on the other hand, was not significantly different between participants' academic programs. Data analysis also revealed no correlational relationship between students' self-confidence level and their language skills and their performance. The study raises more questions about other vital factors such as course instructors' views of the materials, faculty members of the target department, family belief in the usefulness of the program, protentional employers. These views and beliefs shape the student's preparation process and therefore, should be explored further.
The Interplay between Social Contexts of Power and Aggravation Strategies: Identity- specific Perspectives in Fictional Discourse
Authors: Kumar V.Vinod , Thakur Vijay Singh , James Justin
Published: October 2019

This paper attempts a pragmatic analysis of the interplay between social contexts of power and sociolinguistic device of aggravation strategies concerning dialogic discourses in Vikram Seth’s novel A Suitable Boy (ASB) (1993). The paper attempts to validate that aggravation strategies have been an integral part of human discourse. It demonstrates how people use aggravation strategies to exercise power over others in different communicative contexts. It also exemplifies how power is vested in specific identities, and their role relationships in different power structures existing in the society based on their caste, age, sex, social standing, political or official identity, and how the power is exerted in the context of their social identities. The paper defines various aspects of aggravation, explains the dominant participatory identities, namely master identities, situated identities, and discourse identities and analyses how these social identities exercise power through aggravation strategies in the dialogic discourses in ASB.
GENETIC DIVERSITY OF HONEY BEE POPULATIONS IN TURKEY BASED ON MICROSATELLITE MARKERS: A COMPARISON BETWEEN MIGRATORY VERSUS STATIONARY APIARIES AND ISOLATED REGIONS VERSUS REGIONS OPEN TO MIGRATORY BEEKEEPING
Authors: Kükrer Mert
Published: October 2019

The honey bee (Apis mellifera L.) is a globally significant species of apparent economic and ecological importance. Recent reports from Spain, Italy and Greece point to an intense admixture of honey bee populations signified by a loss of population structure. This is mostly attributed to migratory beekeeping practices and replacement of queens or colonies with commercial ones that are usually from non-native races or hybrids of different subspecies. These two practices are also heavily carried out in parts of Turkey where almost three-quarters of the 6 million colonies are transferred seasonally from one region to other.Past research using microsatellite and RAPD markers, mtDNA, allozymes and geometric morphometry revealed the presence of five different subspecies of honey bees (meda, syriaca,caucasica, anatoliaca and an ecotype from Carniolan subspecies group) inTurkey. Here, we carried out an analysis of population structure of Turkish honeybees sampled from six different regions (n = 250) during the period 2010-2012. A total of 29 microsatellite markers were used in four multiplex reactions. The results show that population structure is preserved in general although there are signs of gene flow between the clusters.Overall FST between stationary colonies was calculated as 0,067. For migratory colonies the value was 0,015 and for all the 250 samples the value was 0,047. Four different clusters corresponding to geographical distributions of four subspecies were revealed in structure analysis. The differentiation between the clusters was also apparent in PCA and FCA as well as phylogenetic trees constructed based on genetic distances.The genetic impact of migratory beekeeping was demonstrated for the first time based on a comparison of assignment probabilities of individuals from migratory and stationary colonies to their geographic populations. Another comparison between regions that are either open to migratory beekeeping or closed let us to evaluate the status of isolated regions and showed the importance of establishing such regions. The effects of queen and colony trade were revealed by the presence of introgression from the highly commercial Caucasian bees. Our findings confirm the previously observed high levels geographically structured genetic diversity in honey bees of Turkey and emphasize the need to develop policies to maintain this diversity.

Authors: Ojokoh Bolanle , Akinsulire Victor , Isinkaye Folasade O
Published: October 2019

The essence of evaluating employees’ performance in any tertiary institution is to realize the goals of the institution by measuring the contribution of each employee. Effective human resource evaluation is paramount to the development of any organization. An automated method is needed to remove the limitations and facilitate the duties of human resource management. In this paper, rough set theory, a mathematical technique that deals with vagueness and uncertainty of imperfect data analysis is adopted for the evaluation of academic staff profile for promotion, grants and other academic purposes. The entire appraisal process of academic staff was translated into a web-based application where every user can fill, edit, update, and submit the annual performance evaluation report form. The indiscernible property of rough set approach is a unique factor in assessing every academic staff under the department and faculty/school by the head of department and dean respectively. With this, the system generates an information table handling all the necessary conditions for promoting academic staff and the corresponding decisions taken. A model for rating publications was proposed to reduce the sentiments involved in manual rating. Reports were generated as output of each evaluation procedure. One hundred (100) dataset of academic staff of the Federal University of Technology, Akure, Nigeria was used in the experiment to evaluate the performance of the system. The results of the system obtained score were compared with the institution standard and it was found that the system scores were above standard, the average precision of the system shows 60% effectiveness which showed that the proposed system is efficient for academic performance evaluation process.

Authors: Downs Gabby , Upadhyay Devang , Mandjiny Sivanadane , Frederick Jeff , Holmes Leonard
Published: October 2019

Entomopathogenic nematodes (in the genus Steinernema and Heterorhabditis) have been studied and successfully commercialized as biological control agents. These organisms are highly virulent and safe for the non-target environment, animals and humans. For at least 200 target species, the nematode-bacteria complex has the potential to become a mass-marketed agricultural biopesticide. However, before nematodes can be successfully integrated into the agricultural system as a regular-use, “go-to” biopesticide, it is necessary to develop economical manufacturing processes. There are several manufacturing platforms: in vitro solid fermentation; in vitro liquid fermentation; and in vivo production. This review presents an analysis of each approach and discusses the advantages and disadvantages relative to the cost of production, technical expertise required, and quality of the final product.

Exploiting Sparse Statistics for a Sequence-Based Prediction of the Effect of Mutations
Authors: Mezei Mihaly
Published: October 2019

Recent work showed that there is a significant difference between the statistics of amino acid triplets and quadruplets in sequences of folded proteins and randomly generated sequences. These statistics were used to assign a score to each sequence and make a prediction whether a sequence is likely to fold. The present paper extends the statistics to higher multiplets and suggests a way to handle the treatment of multiplets that were not found in the set of folded proteins. In particular, foldability predictions were done along the line of the previous work using pentuplet statistics and a way was found to combine the quadruplet and pentuplets statistics to improve the foldability predictions. A different, simpler, score was defined for hextuplets and heptuplets and were used to predict the direction of stability change of a protein upon mutation. With the best score combination the accuracy of the prediction was 73.4%.
Characterization of Biochars Produced from Dairy Manure at High Pyrolysis Temperatures
Authors: Tsai Wen-Tien , Huang Po-Cheng , Lin Yu-Quan
Published: October 2019

In this work, the thermochemical analyses of dairy manure (DM), including the proximate analysis, ultimate (elemental) analysis, calorific value, thermogravimetric analysis (TGA), and inorganic elements, were studied to evaluate its potential for producing DM-based char (DMC) with high porosity. The results showed that the biomass should be an available precursor for producing biochar materials based on its high contents of carbon (42.63%) and volatile matter (79.55%). In order to characterize their pore properties, the DMC products produced at high pyrolysis temperatures (500–900°C) were analyzed using surface area and porosity analyzer, pycnometer, and scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS). The values of pore properties for the DMC products increased with an increase in pyrolysis temperature, leading to more pore development and condensed aromatic cluster at elevated temperatures. Because of the microporous and mesoporous structures from the N2 adsorption–desorption isotherms with the hysteresis loops (H4 type), the Brunauer–Emmett–Teller (BET) surface area of the optimal biochar (DMC-900) was about 360 m2/g, which was higher than the data reported in the literature. The highly porous structure was also seen from the SEM observations. More significantly, the cation exchange capacity (CEC) of the optimal DMC product showed a high value of 57.5 ± 16.1 cmol/kg. Based on the excellent pore and chemical properties, the DMC product could be used as an effective amendment and/or adsorbent for the removal of pollutants from the soil media and/or fluid streams.

Published: October 2019

Genomic selection (GS) has been widely considered as a valuable strategy for enhancing the rate of genetic gain in farm animals. However, the construction of a large reference population is a big challenge for small populations like indigenous cattle. In order to evaluate the potential application of GS for Chinese indigenous cattle, we assessed the influence of combining multiple populations on the reliability of genomic predictions for 10 indigenous breeds of Chinese cattle using simulated data. Also, we examined the effect of different genetic architecture on prediction accuracy. In this study, we simulated a set of genotype data by a resampling approach which can reflect the realistic linkage disequilibrium pattern for multiple populations. We found within-breed evaluations yielded the highest accuracies ranged from 0.64 to 0.68 for four different simulated genetic architectures. For scenarios using multiple breeds as reference, the predictive accuracies were higher when the reference was comprised of breeds with a close relationship, while the accuracies were low when prediction were carried out among breeds. In addition, the accuracy increased in all scenarios with the heritability increased. Our results suggested that using meta-population as reference can increase accuracy of genomic predictions for small populations. Moreover, multi-breed genomic selection was feasible for Chinese indigenous populations with genetic relationships.

The aim of this work is to describe the change of physical properties of the callus material with the use of the proposed mathematical model for callus remodeling. Callus tissue can be considered as a biomaterial where it’s properties change over time due to the stimulated healing process. The proposed model is based on the mechanical stimulus theory. It is used to estimate the stress-stimulated change in the callus, Young’s modulus, and the density in the case of a mandible fracture. Three healing loading programs are discussed and compared: optimal, intermittent, and intermittent with residual load. Here, the optimal loading program is understood as the in-time change of stimulating loads, which results in the shortest necessary healing time and, simultaneously, in the most uniform distribution of material density in the analyzed domain. The necessary healing time is a period after which the callus density (and hence the Young’s modulus) reaches the desired value. The results of the study suggest a significant difference in the value of the callus maximal density between all three analyzed loading programs for a given healing time interval. The highest values of the density are obtained using the optimal loading program, however, all three programs provide satisfactory density distributions. The analytical results are compared with the callus density estimation based on the computer tomography (CT) medical data.

The Single Shot MultiBox Detector (SSD) is one of the fastest algorithms in the current target detection field. It has achieved good results in target detection but there are problems such as poor extraction of features in shallow layers and loss of features in deep layers. In this paper, we propose an accurate and efficient target detection method, named Single Shot Object Detection with Feature Enhancement and Fusion (FFESSD), which is to enhance and exploit the shallow and deep features in the feature pyramid structure of the SSD algorithm. To achieve it we introduced the Feature Fusion Module and two Feature Enhancement Modules, and integrated them into the conventional structure of the SSD. Experimental results on the PASCAL VOC 2007 dataset demonstrated that FFESSD achieved 79.1% mean average precision (mAP) at the speed of 54.3 frame per second (FPS) with the input size 300 × 300, while FFESSD with a 512 × 512 sized input achieved 81.8% mAP at 30.2 FPS. The proposed network shows state-of-the-art mAP, which is better than the conventional SSD, Deconvolutional Single Shot Detector (DSSD), Feature-Fusion SSD (FSSD), and other advanced detectors. On extended experiment, the performance of FFESSD in fuzzy target detection was better than the conventional SSD.

High levels of atmospheric concentration of PM2.5 (particulate matters less than 2.5 μm in size) are one of the most urgent societal issues over the East Asian countries. Air quality models have been used as an essential tool to predict spatial and temporal distribution of the PM2.5 and to support relevant policy making. This study aims to investigate the performance of high-fidelity air quality models in simulating surface PM2.5 chemical composition over the East Asia region in terms of a prediction consistency, which is a prerequisite for accurate air quality forecasts and reliable policy decision. The WRF-Chem (Weather Research and Forecasting-Chemistry) and WRF/CMAQ (Weather Research and Forecasting/Community Multiscale Air Quality modeling system) models were selected and uniquely configured for a one-month simulation by controlling surface emissions and meteorological processes (model options) to investigate the prediction consistency focusing the analyses on the effects of meteorological and chemical processes. The results showed that the surface PM2.5 chemical components simulated by both the models had significant inconsistencies over East Asia ranging fractional differences of 53% ± 30% despite the differences in emissions and meteorological fields were minimal. The models’ large inconsistencies in the surface PM2.5 concentration were attributed to the significant differences in each model’s chemical responses to the meteorological variables, which were identified from the multiple linear regression analyses. Our findings suggest that the significant models’ prediction inconsistencies should be considered with a great caution in the PM2.5 forecasts and policy support over the East Asian region.

In this study, we investigated the possible teleconnection between PM10 concentrations in South Korea and Arctic Sea ice concentrations at inter-annual time scales using observed PM10 data from South Korea, NCEP R2 data, and NOAA Sea Ice Concentration (SIC) data from 2001 to 2018. From the empirical orthogonal function (EOF) analysis, we found that the first mode (TC1) was a large-scale mode for PM10 in South Korea and explained about 27.4% of the total variability. Interestingly, the TC1 is more dominantly influenced by the horizontal ventilation effect than the vertical atmospheric stability effect. The pollution potential index (PPI), which is defined by the weighted average of the two ventilation effects, is highly correlated with the TC1 of PM10 at a correlation coefficient of 0.75, indicating that the PPI is a good measure for PM10 in South Korea at inter-annual time scales. Regression maps show that the decrease of SIC over the Barents Sea is significantly correlated with weakening of high pressure over the Ural mountain range region, the anomalous high pressure at 500 hPa over the Korean peninsula, and the weakening of the Siberian High and Aleutian low. Moreover, these patterns are similar to the correlation pattern with the PPI, suggesting that the variability of SIC over the Barents Sea may play an important role in modulating the variability of PM10 in South Korea through teleconnection from the Barents Sea to the Korean peninsula via Eurasia.

Physical activity improves the prognosis of cancer patients, partly by contrasting the associated muscle wasting (cachexia), through still unknown mechanisms. We asked whether aerobic exercise causes secretion by skeletal muscles of proteins (myokines) that may contrast cachexia. Media conditioned by peroxisome proliferator-activated receptor γ coactivator 1α (PGC1α)-expressing myotubes, reproducing some metabolic adaptations of aerobic exercise, as increased mitochondrial biogenesis and oxidative phosphorylation, restrained constitutively active Forkhead box-containing subfamily O3 (caFoxO3)-induced proteolysis. Microarray analysis identified amphiregulin (AREG), natriuretic peptide precursor B (NppB), musclin and fibroblast growth factor 18 (FGF18) as myokines highly induced by PGC1α. Notably, only musclin tended to be low in muscle of mice with a rare human renal carcinoma; it was reduced in plasma and in muscles of C26-bearing mice and in atrophying myotubes, where PGC1α expression is impaired. Therefore, we electroporated the Tibialis Anterior (TA) of C26-bearing mice with musclin or (its receptor) natriuretic peptide receptor 3 (Npr3)-encoding plasmids and found a preserved fiber area, as a result of restrained proteolysis. Musclin knockout (KO) mice lose more muscle tissue during growth of two distinct cachexia-causing tumors. Running protected C26-bearing mice from cachexia, not changing tumor growth, and rescued the C26-induced downregulation of musclin in muscles and plasma. Musclin expression did not change in overloaded plantaris of mice, recapitulating partially muscle adaptations to anaerobic exercise. Musclin might, therefore, be beneficial to cancer patients who cannot exercise and are at risk of cachexia and may help to explain how aerobic exercise alleviates cancer-induced muscle wasting.
