Authors: Babai Zsófia , Kovácsné Vinkovics Éva
Published: July 2020

Im folgenden Beitrag möchten wir die Prinzipien und die Praxis des kommunikations- und erlebnisorientierten Fremdspracherwerbs in der frühen Kindheit vorstellen. Das Ergebnis der Zweitsprachförderung hängt hauptsächlich von der Persönlichkeit der PädagogInnen und ihren Methoden, aber auch von der Motivation der Kinder ab. Der wichtigste Faktor bei der frühen Sprachförderung ist der erlebnisorientierte Prozess, der in den Themen des Kindergartenjahres realisiert werden kann. Die Hauptaktivität der Kinder ist die Spieltätigkeit, in der Kinder alltägliche Situationen in der Realität erleben können. Diesen Ansatz integrieren wir in die theoretische Ausbildung der KindergartenpädagogInnen mit Fachgebiet Deutsch, den sie dann in ihrer beruflichen Praxis nutzen können. Im vorliegenden Beitrag soll die Aufmerksamkeit auf die Notwendigkeit der Durchsetzung der erlebnis- und kommunikationsorientierten Zweitsprachvermittlung gelenkt werden, die beim erfolgreichen Erwerb und bei der nachhaltigen Entwicklung der Fremdsprachenkenntnisse unerlässlich ist.

The 1906 Dobrá Voda Earthquake (M=5.7) at the Vienna Basin Transfer Fault: evaluation of the ESI2007 intensity and analysis of the aftershock sequence
Authors: Nasir Asma , Hintersberger Esther , Decker Kurt
Published: July 2020

Aftershock identification plays an important role in the assessment and characterization of large earthquakes. Especially, the length of the aftershock sequence is an important aspect of declustering earthquake catalogues and therefore impacts the frequency of earthquakes in a certain region, which is important for future seismic hazard assessment. However, in intraplate regions with low deformation rates and low to moderate seismicity, it is still questionable if aftershocks after a major event may continue for much longer time. In this study, we use one of the earliest instrumentally recorded earthquakes, the 1906 Dobrá Voda earthquake (Ms/Imax=5.7/VIII-IX), to compare different approaches of aftershock determination and their suitability for understanding the recorded earthquake sequence. The Dobrá Voda segment of the Vienna Basin Transfer Fault System is one of the seismically most active zones in Slovakia with the 1906 earthquake as the strongest recorded earthquake. We first assess the epicentral intensity of the earthquake according to the Environmental Intensity Scale (ESI2007) using contemporary descriptions of earthquake effects. This additional information leads to constrain the maximal intensity to IESI2007=IX. This result agrees well with first the assessment of Imax in 1907 and indicates the reliability of this intensity data. In the second step, earthquake data are plotted for two spatial windows extending 13 km and 26 km from the epicenter of the mainshock, respectively. Despite uncertainties regarding the completeness of data due to war times and lack of nearby seismic stations, the overall temporal evolution of seismicity can apparently not be described as an Omori-type aftershock sequence following the event in 1906. Instead, earthquake occurrence within 13 km of the mainshock shows elevated earthquake activity right after the 1906 event that only decays to a lower level of activity within decades after the mainshock. The decline of seismicity therefore occurs over time scales which are much longer than those predicted by the Omori relation. We conclude that today’s seismic activity may still be affected by the 1906 earthquake.
The Laurentian Neoproterozoic Glacial Interval: reappraising the extent and timing of glaciation
Authors: Le Heron Daniel Paul , Eyles Nicholas , Busfield Marie Elen
Published: July 2020

One of the major issues in Neoproterozoic geology is the extent to which glaciations in the Cryogenian and Ediacaran periods were global in extent and synchronous or regional in extent and diachronous. A similarly outstanding concern is determining whether deposits are truly glacial, as opposed to gravitationally initiated mass flow deposits in the context of a rifting Rodinia supercontinent. In this paper, we present 115 publically available, quality-filtered chronostratigraphic constraints on the age and duration of Neoproterozoic glacial successions, and compare their palaeocontinental distribution. Depositional ages from North America (Laurentia) clearly support the idea of a substantial glacial epoch between about 720-660 Ma on this palaeocontinent but paradoxically, the majority of Australian glacial strata plot outside the previously proposed global time band for the eponymous Sturtian glaciation, with new dates from China also plotting in a time window previously thought to be an interglacial. For the early Cryogenian, the data permit either a short, sharp 2.4 Ma long global glaciation, or diachronous shifting of ice centres across the Rodinia palaeocontinent, implying regional rather than global ice covers and asynchronous glacial cycles. Thus, based on careful consideration of age constraints, we suggest that strata deposited in the ca. 720-660 Ma window in North America are better described as belonging to a Laurentian Neoproterozoic Glacial Interval (LNGI), given that use of the term Sturtian for a major Neoproterozoic glacial epoch can clearly no longer be justified. This finding is of fundamental importance for reconstructing the Neoproterozoic climate system because chronological constraints do not support the concept of a synchronous panglacial Snowball Earth. Diachroneity of the glacial record reflects underlying palaeotectonic and palaeogeographic controls on the timing of glaciation resulting from the progressive breakup of the Rodinian supercontinent.
Representations of Teachers and Elder Schoolchildren about the Risks of Interacting with the Internet
Authors: Panov V.I. , Patrakov E.V.
Published: July 2020

The paper explores the notions of risks on the Internet in teachers and high school students. The study was carried out on a sample of teachers (n = 294) and school students of 9—11 grades (n = 180) using the analysis of social representations (Abric coefficient).The results confirmed that only a small part (5 out of 29) of the teachers’ notions about the riskiness of Internet communication is related to the use of the Internet; mostly they are based on some general ideas concerning risk behaviours in adolescents. At the same time, the teachers were not quite ready to cooperate with their colleagues to help reduce such risks: only 41.5% of the teachers showed readiness, given that they receive appropriate training. The study confirmed that the notions of risks associated with the active use of the Internet differ significantly in teachers and students, which can be explained by at least two reasons. Firstly, by the fact that the active use of the Internet does not affect the subjective well-being of the adolescents. Secondly, by the fact that for high school students, the Internet is a natural tool and a necessary attribute of their daily life, whereas, according to the outcomes of our study, only 20% of the teachers believe that they have the necessary skills to freely use the Internet as a means of their teaching activities. For the rest of the teachers, the Internet is still an object that must be mastered and treated as a source of threats and risks to the psychological development of schoolchildren.
Assessment of Creative Movement in Preschool Children
Authors: Gorshkova E.V.
Published: July 2020

The paper presents a technique for assessing features of creative movement in children aged 3—6 years; the technique was used to test the hypothesis about the specifics of these features in each of the preschool ages. The paper outlines the creative task and the entire procedure of the technique; describes the parameters of creative movement (the use of various expressive movements, their originality, transformation into the character etc.) and the system of their assessments. The study involved 205 children aged 3—6 and the paper discusses the obtained data: compares the developmental dynamics of creative movement basing on its parameters and the correlation between them; provides intermediate conclusions concerning the predominance of the cognitive aspect of creativity (“use of means” of the language of movements) over the actual creative aspect (“transformation into the character”, “originality”).
Online and Offline Behavior: Two Realities or One?
Authors: Bovina I.B. , Dvoryanchikov N.V.
Published: July 2020

The paper focuses on a social psychological analysis of the effects of new technologies on the individual and his/her social experience. Among the impacts of social media on everyday life are the transformation and simplification of communication process, as well as the transformation of power relations and norms associated with this process. Participants of communication process have various opportunities to maintain anonymity, to construct and modify identities, and to interrupt and or even to terminate communication process at any time. The literature review reveals the negative side of the Internet use and demonstrates antinormative phenomena. The explanations of aggressive online behaviour, as well as the attempts to predict offline behaviour from online observations, are based on a wide range of interindividual constructs. However, these studies are mostly descriptive. The paper highlights the potential of social psychological knowledge (social cognitive theory, social representations theory and deindividuation theory) to answer the question about the relationship of online and offline behaviour. The theory of social representations may also be of much use in creating prevention programmes for adolescents and young people.
Short-Term Probabilistic Hazard Assessment in Regions of Induced Seismicity
Authors: Teng Ganyu , Baker Jack W.
Published: July 2020

This project introduces short-term hazard assessment frameworks for regions with induced seismicity. The short-term hazard is the hazard induced during the injection for hydraulic-fracturing-induced earthquakes. For wastewater-disposal-induced earthquakes, it is the hazard within a few days after an observed earthquake. In West Texas, hydraulic-fracturing-induced earthquakes cluster around the injection activities, and the earthquake occurrence varies greatly in time and space. We develop a method to estimate the hazard level at the production site during the injection, based on past injection and earthquake records. The results suggest that the injection volume has a negligible effect on short-term earthquake occurrence in this case, because injection volumes per well fall within a relatively narrow range, whereas the regional variations in seismic productivity of wells and b-values are important. The framework could be easily modified for implementation in other regions with hydraulic-fracturing-induced earthquakes. We then compare the framework with wastewater-disposal-induced earthquakes in Oklahoma–Kansas and natural earthquakes in California. We found that drivers of short-term seismic hazard differ for the three cases. In West Texas, clustered earthquakes dominate seismic hazards near production sites. However, for Oklahoma–Kansas and California, the short-term earthquake occurrence after an observed mainshock could be well described by the mainshock–aftershock sequence. For Stillwater in Oklahoma, aftershocks contribute less to the hazard than San Francisco in California, due to the high Poissonian mainshock rate. For the rate of exceeding a modified Mercalli intensity of 3 within 7 days after an M 4 earthquake, the aftershock sequence from natural earthquakes contributed 85% of the hazard level, whereas the aftershock contribution was only 60% for induced earthquakes in Oklahoma. Although different models were implemented for hazard calculations in regions with hydraulic fracturing versus wastewater injection, injection activities could be drivers of short-term hazard in both cases.
A Long-Lived Swarm of Hydraulic Fracturing-Induced Seismicity Provides Evidence for Aseismic Slip
Authors: Eyre Thomas S. , Zecevic Megan , Salvage Rebecca O. , Eaton David W.
Published: July 2020

Seismic swarms are defined as an increase in seismicity that does not show a clear mainshock–aftershock sequence. Typically, swarms are primarily associated with either fluid migration or slow earthquakes (aseismic slip). In this study, we analyze a swarm induced by hydraulic fracturing (HF) that persisted for an unusually long duration of more than 10 months. Swarms ascribed to fluid injection are usually characterized by an expanding seismicity front; in this case, however, characteristics such as a relatively steady seismicity rate over time and lack of hypocenter migration cannot be readily explained by a fluid-diffusion model. Here, we show that a different model for HF-induced seismicity, wherein an unstable region of a fault is loaded by proximal, pore-pressure-driven aseismic slip, better explains our observations. According to this model, the steady seismicity rate can be explained by a steady slip velocity, while the spatial stationarity of the event distribution is due to lateral confinement of the creeping region of the fault with increased pore pressure. Our results may have important implications for other induced or natural seismic swarms, which could be similarly explained by aseismic loading of asperities driven by fluid overpressure rather than the often-attributed fluid-migration model.
Long- and Short-Term Stress Interaction of the 2019 Ridgecrest Sequence and Coulomb-Based Earthquake Forecasts
Authors: Toda Shinji , Stein Ross S.
Published: July 2020

We first explore a series of retrospective earthquake interactions in southern California. We find that the four Mw≥7 shocks in the past 150 yr brought the Ridgecrest fault ∼1  bar closer to failure. Examining the 34 hr time span between the Mw 6.4 and Mw 7.1 events, we calculate that the Mw 6.4 event brought the hypocentral region of the Mw 7.1 earthquake 0.7 bars closer to failure, with the Mw 7.1 event relieving most of the surrounding stress that was imparted by the first. We also find that the Mw 6.4 cross-fault aftershocks shut down when they fell under the stress shadow of the Mw 7.1. Together, the Ridgecrest mainshocks brought a 120 km long portion of the Garlock fault from 0.2 to 10 bars closer to failure. These results motivate our introduction of forecasts of future seismicity. Most attempts to forecast aftershocks use statistical decay models or Coulomb stress transfer. Statistical approaches require simplifying assumptions about the spatial distribution of aftershocks and their decay; Coulomb models make simplifying assumptions about the geometry of the surrounding faults, which we seek here to remove. We perform a rate–state implementation of the Coulomb stress change on focal mechanisms to capture fault complexity. After tuning the model through a learning period to improve its forecast ability, we make retrospective forecasts to assess model’s predictive ability. Our forecast for the next 12 months yields a 2.3% chance of an Mw≥7.5 Garlock fault rupture. If such a rupture occurred and reached within 45 km of the San Andreas, we calculate it would raise the probability of a San Andreas rupture on the Mojave section by a factor of 150. We therefore estimate the net chance of large San Andreas earthquake in the next 12 months to be 1.15%, or about three to five times its background probability.
Safety performance functions in Dedicated Bus Lane of BRT on Caracas Avenue Corridor at Bogotá city
Authors: Rodríguez Polo Kelly Andrea , Henao Pérez Santiago
Published: July 2020

Introduction- Road safety is a global concern due to the fact that traffic accidents represent serious temporary and / or permanent damage to the health of those involved. On the other hand, the Bus Rapid Transit (BRT) systems carries a large volume of passengers and during their operation; they are involved in this problem.
Objective- Accident prediction model implemented in the Highway Safety Manual 2010 or HSM is an alternative to evaluate the strategies that allow to reduce accidents in this type of systems. However, there is not specified safety performance functions (SPFs) developed for BRT systems. In the present work, the accident model of HSM is adapted by calibration of general SPFs expressions of the manual and also, SPFs were developed for BRTs installed on the central-line of main roads and use an exclusive lane of all other transport systems (both public or private) and mobility (e.g. bike paths).
Method / Results - Crashes reports and traffic volumes data supplied by the Department of Transportation of Bogotá were used. The model was calibrated using the safety performance functions (SPFs) of the HSM and a specific developed functions for the BRT conditions. These SPFs were developed using a negative binomial model in roadway segments and intersections.
Conclusions- Through the validation, it was found that the functions developed have a better fit than the established SPF of the HSM. The developed SPFs can be used as a tool to define safety performance guidelines of Bogotá's BRT corridors in the coming years.

Background: This study was undertaken to compare the efficacy and safety of the new technology tight junction modulation (TJM) bimatoprost 0.01% (TJM-bimatoprost), containing polyhexamethylene biguanide hydrochloride as a preservative, and marketed bimatoprost 0.01% (BKC-bimatoprost) in healthy beagle dogs.Methods: This was a cross-over study and all animals in the study were assigned to one of two treatment arms to receive either TJM-bimatoprost (n=6) or BKC-bimatoprost (n=6) ophthalmic solution. Dosing for period 1 was started on day 3 (8 am everyday) and it continued till day 12. Assessments were carried out every day at 8 am, 9 am, 2 pm and 8 pm throughout the study period till day 17.Results: For the pooled analysis (n=12 in each group) of period 1 and 2, there was a significant decrease (p<0.001) in mean intra-ocular (IOP) 1 hour post administration as compared to the baseline and this trend continued all throughout the study in both treatment arms. Twenty fours after last dose, on day 12, IOP measurements were 14.20±1.59 mmHg and 13.89±1.5 mmHg in the TJM-bimatoprost and the BKC-bimatoprost group respectively. The analysis of the primary end point revealed that 95% confidence interval for the between group differences in mean IOP values were well within the pre-defined equivalence margin of ±1.5 mmHg. In terms of safety, there was no difference in mean pupillary diameter in the TJM-bimatoprost and BKC-bimatoprost group.Conclusions: The results of this study enhance our understanding of the proprietary TJM technology by establishing efficacy and safety of TJM-bimatoprost in animal models.
Does increasing the number of inseminations per cycle increase the probability of conception? a randomized trial comparing single versus double intrauterine insemination
Authors: Khandavalli Yasaswi , Rai Seema , Lodha Rama Singodiya
Published: July 2020

Background: Intrauterine insemination (IUI) remains an inexpensive, non-invasive, and effective first-line artificial insemination technique. The technique of IUI has evolved through various innovations since the time Cohen published the first report of IUI in 1962, and the success rate increased from 5% to >20%. The success of IUI depends upon several factors; two such prognostic factors are the timing and frequency of insemination.  The objective of this study was to compare the effectiveness of single versus double intrauterine insemination.Methods: This prospective randomized study was carried out in 130 patients with male factor infertility, PCOS and unexplained infertility. Patients were randomly assigned into two groups. In the first group of 65 patients, single IUI was applied at 36 to 40 hours after HCG administration, to the other 65 patients in the second group, double IUIs were applied at 12 to 16 hours and 36 to 40 hours after HCG administration. The primary end-point of the study was to compare the clinical pregnancy rate between the two groups.Results: The overall pregnancy rate was 18.46% (12/65) for single IUI group and 30.76% (20/65) for double IUI group. There was a no statistically significant difference between single and double IUI groups (p=0.16).Conclusions: This study did find a higher pregnancy rate following double IUI; however, the difference was not statistically significant. Further, larger sample size studies are required to determine if double IUI increases the pregnancy rate.

Metodologicamente, utilizou-se das legislações do Corpo de Bombeiros do Estado de Alagoas e a Norma Regulamentadora 23 (NR-23) para avaliar aspectos relacionados ao sistema de hidrantes, reserva de incêndio, saída de emergência, escadas, ascensores e portas corta-fogo. Verificou-se que, embora alguns aspectos do ‘bloco de salas de aula’ atendam aos requisitos estabelecidos pelas Legislações, a maioria dos parâmetros avaliados não estavam de acordo com o mínimo estabelecido, como, por exemplo, volume insuficiente de água necessário para reserva de incêndio, a ausência de brigada de incêndio, obstáculos nas saídas de emergência e presença de escadas feitas de material que propaga calor. Concluiu-se que o bloco de salas de aula não se encontra dentro das exigências das Legislações no que tange a prevenção e combate a incêndio, sendo necessárias intervenções para garantir a segurança das pessoas em um eventual incêndio.

Published: July 2020

Este trabalho analisou o estresse ocupacional em 19 profissionais de saúde dos centros de atenção psicossocial – CAPS, em um município do sertão paraibano. Avaliou-se os níveis de estresse em que esses profissionais se encontravam bem como os sintomas e as queixas mais frequentes vivenciados por estes profissionais nos últimos dois meses. Os dados foram coletados através de dois questionários, um sócio demográfico para levantamento da população e o teste de Baccaro para identificação do estresse. A idade média dos profissionais era de 35 anos (s=8,5), dos quais 10 (52,6%) eram do sexo masculino e 9 (47,4%) do sexo feminino. Os resultados apontaram que 73,7% estavam em um grau de estresse moderado e os sintomas mais frequentes eram problemas musculoesqueléticos e alterações do sistema nervoso. Os dados mostraram que os profissionais da saúde são acometidos pelo estresse e seus estressores, merecendo maiores pesquisas e elucidações a cerca deste tema que vem sendo tratado nos últimos anos como um dos grandes causadores de doenças.

A Análise Ergonômica do Trabalho é um instrumento importante para os profissionais responsáveis em conceber espaços e postos de trabalho, levando em consideração as variáveis fisiológicas, psicológicas e cognitivas do trabalhador, permitindo assim, melhorar a qualidade de vida no ambiente laboral. Diante disso, a presente pesquisa, utilizando dessa ferramenta, buscou avaliar a relação entre as condições de trabalho e o ambiente construído a que estão submetidos os operadores de caixa de uma agência bancaria localizada no município de Abaetetuba-PA. Os resultados demonstraram que os funcionários são acometidos com desconfortos físicos e mentais devido à repetitividade dos movimentos, elevada carga de trabalho e locação inadequada dos mobiliários e equipamentos. Com isso, constatou-se que o ambiente necessita de melhorias para atender às necessidades psicofisiológicas dos trabalhadores e ao que estabelece a legislação vigente. Entre as medidas corretivas indicadas incluem-se o estabelecimento de um maior número de pausas para descanso e educação postural, além de modificações da disposição dos equipamentos e mobiliários, de acordo com as características antropométricas de cada indivíduo.

Touching is Worlding: From Caring Hands to World-Making Dances in Multispecies Childhoods
Authors: Tammi Tuure , Hohti Riikka
Published: July 2020

In this article we analyze the phenomenon of touch to discuss care and knowing within child-animal relations. The empirical part was conducted as a multispecies ethnography in a comprehensive school with an educational zoo built in a huge greenhouse. Storytelling, Despret’s idea of “versions,” and insights drawn from dance are used to take a close look at touching events between the research participants. From observations of caring hands and the material-discursive dimensions involved in stroking, the article moves on to consider ways of knowing and not-knowing that intertwine and are produced in touch. Finally, touch is discussed as a complex worlding dance that always takes more than two.
Mapping Child-Animal Care Relations in Shaun Tan’s Tales from Outer Suburbia
Authors: Mulvenna Amy
Published: July 2020

This article explores caring relations between child characters and sentient animals in two tales by Australian author-illustrator Shaun Tan. Each of Tan’s 15 Tales from Outer Suburbia are set in an “outer” suburban world replete with curious critters. These include a silent and stoic water buffalo, an unmoving dugong (manatee), and other surprising companion species. In this article, the author unpacks the caring relationships between child protagonists and the sentient creatures they encounter in two selected tales by focusing specifically on those processes that bring these characters together in curious encounters: that is, processes of embodied mapping. Emphasis is placed on enchantment and movement, and, in particular, moments given to pausing, lingering, and reflection. The author argues that both the fields of human-animal studies and the social studies of childhood can gain from exploration of the subtleties of these moments.
Caring, Relating, and Becoming: Child-Horse Relationships in Equestrian Leisure
Authors: Mukherjee Utsa
Published: July 2020

This article theorizes child-horse relations and explores the role of care therein. The existing body of research on human-animal relationships in the context of equestrian sport and leisure has for the most part eschewed children’s narratives. Drawn from a wider project on British Indian children’s everyday leisure, this article presents a case study of a child engaged in horse riding as a structured leisure activity. Using interview data with the child and her parents, the analysis demonstrates that child-equine care relationships are reciprocal and unfold within a wider set of social relationships or what I call “multispecies generational order.”
О КЛАССИЧЕСКОМ РЕШЕНИИ СМЕШАННОЙ ЗАДАЧИ ДЛЯ ЛИНЕЙНОГО НЕСТРОГО ГИПЕРБОЛИЧЕСКОГО УРАВНЕНИЯ ЧЕТВЕРТОГО ПОРЯДКА С ОДНОЙ КРАТНОЙ ХАРАКТЕРИСТИКОЙ
Authors: Чеб Е. С. , Симинская Е. С.
Published: July 2020

Данная статья посвящена построению классического решения смешанной задачи для линейно- го однородного нестрого гиперболического уравнения четвертого порядка, оператор которого представляет собой четырехкратную композицию одного и того же оператора первого порядка, с постоянными коэффициентами и четырехкратной характеристикой. Для корректной постановки данной задачи граничные условия задаются не на всей боковой границе, что является ее особенностью. Для построения решения используется метод характеристик. Согласно этому методу, в общем решении исходного уравнения присутствуют четыре неизвестные функции, которые на области определения находятся из начальных и граничных условий. Классическое решение построено для случая отсутствия производных младших порядков. Получены достаточные условия гладкости и согласований граничных условий с начальными условиями и уравнением. Гладкость исходных данных нужна для четырежды непрерывной дифференцируемости решения. Условия согласования нужны для четырежды непрерывной дифференцируемости решения на критической характеристике. Доказана теорема существования единственного классического решения этой смешанной задачи. Полученные результаты могут быть применены в теории уравнений с частными производными и в вычислительной математике

Published: July 2020

Este trabalho trata-se de um estudo de caso exploratório sobre a metodologia ativa conhecida como Peer Instruction (PI). Seu objetivo geral é compreender o funcionamento dessa metodologia e as teorias envolvidas por meio da revisão bibliográfica e da prática docente. Adotamos a teoria sociointeracionista de Vigotsky e a teoria de aprendizagem significativa de David Ausubel, como referenciais teóricos para identificação de alguns aspectos do método. Deseja-se investigar o funcionamento do método e a reação dos alunos, sua aplicabilidade na área de Química, suas dificuldades, vantagens e desvantagens. Desta forma, realizou-se o estudo em quatro turmas do primeiro ano do Ensino Médio de uma escola pública da cidade de Viçosa, com cerca de 160 alunos, ao longo de uma sequência didática sobre tópicos de Estequiometria. Observou-se que as discussões entre os pares eram frutíferas e que os alunos demonstraram estar muito motivados com a nova metodologia. Observou-se também que os alunos obtiveram certa resistência à proposta da sala de aula invertida - mesmo sendo um aspecto muito importante para o bom funcionamento do método - na qual eram estimulados a realizar a leitura prévia dos conteúdos antes das aulas. Concluiu-se que o PI é um método adequado para o ensino de química. Este estudo permitiu aos alunos, a elucidação de conceitos importantes e subjacentes e proporcionou novas ideias e novos horizontes acerca do método e continuidade da pesquisa.
