The term behavioral problem’ refers to a type of serious abnormality in the behavior of an individual resulting into his maladjustment with the self and the environment and proving detrimental to the welfare of his self and the society. Example of such behavior is truancy, lying, stealing; temper tantrums, drug addiction and juvenile delinquency. Truancy is a behavioral problem relates with students in school at all levels of education. The researcher carried out a theoretical work by using counseling techniques in tackling the problem of truancy in schools’ of Uttarakhand, various techniques were used in resolving problem of truancy in Uttarakhand schools include Rational Emotive Behavioural Therapy (REBT) of Albert Ellis and Behavioural Modification include; modeling, assertiveness training, cognitive restructuring, behavioural modification, reinforcement both positive and negative. Effects of truancy on academic performance of the students in schools were spelt out. Various counseling implications were discussed which include; the need to form an attendance review team to catch problem of truancy as early as possible, provision of individualize support for the children in school, building a positive school culture to guide the child in school and focusing on the most essential behaviors that are noticeable in schools. Problem of truancy would definitely be solved if used all the suggested techniques and skills appropriately by a trained professional counseling.

Published: January 2021

Syphilis in pregnant women caused by Treponema pallidum remains a major cause of reproductive morbidity and poor pregnancy outcomes in developing countries. Severe neonatal infections, stillbirths, perinatal deaths, and low birth weight babies are common among mothers with syphilis infection. The aim of the study was to assess the prevalence and risk factors associated to syphilis in pregnant women. A cross-sectional and retrospective studies were conducted among pregnant women who attended the prenatal service at the Gisovu health center. Participants were pregnant women who tested positive for syphilis based on lab results and responses collected from anonymous questionnaires completed with sexual behaviors, demographics, sexual partners, history of abortion, and knowledge about STDs. The prevalence of syphilis was 5.74%. Syphilis was associated to the history of previous abortion (P = 0.005 < 0.05), a low level of education (P = 0.049 < 0.05), and marital status (P = 0.044 < 0.05). The main associated behavioral factor was women who had sex with different partners using condom and did not acquire syphilis infection (P = 0.00 < 0.05). Syphilis is still a public health concern in patients and especially in pregnant women as shown by the findings of this study. It is very important to screen all pregnant women for syphilis and to strengthen the existing antenatal care services and health education on transmission and prevention of the disease.

Cycling and retention of nitrogen in European beech (Fagus
sylvatica L.) ecosystems under elevated fructification frequency
Authors: Brumme Rainer , Ahrends Bernd , Block Joachim , Schulz Christoph , Meesenburg Henning , Klinck Uwe , Wagner Markus , Khanna Partap
Published: January 2021

Abstract. Atmospheric deposition of nitrogen (N) has exceeded its demand for plant increment in forest ecosystems in Germany. High N inputs increased plant growth, the internal N cycling within the ecosystem, the retention of N in soils and plant compartments, and the N output by seepage water. But the processes involved are not fully understood, especially the role of fructification which has increased in its frequency. A field experiment using 15N labelled leaf litter exchange was carried out over a 5.5 years' period at seven long-term monitoring sites with European beech (Fagus sylvatica L.) ecosystems to study the impact of current mast frequency on N cycling. Mean annual leaf litterfall contained 35 kg N ha−1, but about one half of that was recovered in the soil 5.5 years after the establishment of the leaf litter 15N exchange experiment. Retention of leaf litter N in the soil was more closely related to the production of total litterfall than to the leaf litterfall indicating the role of fructification of beech trees in the amount of leaf N retained in the soil. In these forests fructification occurred commonly in intervals of 5 to 10 years, which has now changed to every two to three years as observed during this study period. Seed cupules contributed 51 % to the additional litterfall in mast years which caused a high nutrient demand during their decomposition due to their very high carbon (C) to N and C to phosphorus (P) ratios. Higher mast frequency increased the mass of mean annual litterfall by about 0.5 Mg ha−1 and of litterfall N by 8.7 kg ha−1. Mean net primary production (NPP) increased by about 4 %. Mean total N retention in soils calculated by input and output fluxes was unrelated to total litterfall indicating that mast events were not the primary factor controlling total N retention in soils. Despite reduced N deposition since the 1990s about 5.7 kg N ha−1 out of 20.7 kg N ha−1 deposited annually between 1994 and 2008 were retained in soils notably at acid sites with high N / P and C / P ratios in the organic layers and mineral soils. Ongoing N retention increased the N / P ratios in acid soils with moder type humus forms and reduced the availability of P for plant growth and litter decomposition. Trees retained twice as much N compared to soils by biomass increment particularly in less acid stands where the mineral soils had low C / N ratios.
Technical note: LA–ICP-MS U–Pb dating of unetched and etched apatites
Authors: Abdullin Fanis , Solari Luigi A. , Solé Jesús , Ortega-Obregón Carlos
Published: January 2021

Abstract. The same unetched and chemically etched apatite crystals from five rock
samples were dated by the U–Pb method via laser ablation
inductively coupled plasma mass spectrometry (LA–ICP-MS). The objective of
this study is to test whether chemical etching required for apatite fission
track analysis impacts the precision and accuracy of apatite U–Pb
geochronology. The results of this experiment suggest that etching has
insignificant effects on the accuracy of apatite U–Pb ages obtained by
LA–ICP-MS. Therefore, LA–ICP-MS is reliable for U–Pb analysis as part of
apatite fission track and U–Pb double dating.
Drought-induced non-stationarity in the rainfall-runoff relationship invalidates the
role of control catchment at the Red Hill paired-catchment experimental site
Authors: Zhang Yunfan , Cheng Lei , Zhang Lu , Qin Shujing , Liu Liu , Liu Pan , Liu Yanghe , Xia Jun
Published: January 2021

Abstract. The most widely used approaches for estimating impacts of vegetation changes on runoff are the paired-catchment method, the time-trend analysis method, and the sensitivity-based method. These three methods have yielded consistent results in many paired-catchment studies, except at the Red Hill experimental site in Australia. However, reasons for the inconsistency have not yet been identified. The objective of this study was to identify the reasons for the inconsistency amongst results using observations of two paired catchments from 1990 to 2015. Results from these three methods showed that afforestation accounted for 32.8 %, 93.5 %, and 76.1 % of total runoff changes, respectively. The inconsistency in results were still apparent even the longest available observation record was used. The rainfall-runoff relationship of the control catchment has been used only in the paired-catchment method. This relationship was confirmed to become non-stationary during the pre- and post-calibration periods due to a 10-year prolonged drought, leading to the inconsistency amongst results. By eliminating drought's effects on the rainfall-runoff relationship of the control catchment, afforestation’s contribution to runoff reduction was 73.4 % using the paired-catchment method, agreeing well the other two methods. This study not only revealed the reason for the inconsistent results that had long been observed at the famous experimental site, but also proved, using experimental observations, that prolonged drought can induce non-stationary rainfall-runoff relationship in catchment. It also demonstrated that the stationarity test is vital for correct use of historical time series and effective research on ecological hydrology in the case of frequent extreme climate.
Passive seismic recording of cryoseisms in Adventdalen, Svalbard
Authors: Romeyn Rowan , Hanssen Alfred , Ruud Bent Ole , Stemland Helene Meling , Johansen Tor Arne
Published: January 2021

Abstract. A series of transient seismic events were discovered in
passive seismic recordings from 2-D geophone arrays deployed at a frost
polygon site in Adventdalen, Svalbard. These events contain a high
proportion of surface wave energy and produce high-quality dispersion images
using an apparent offset re-sorting and inter-trace delay minimisation
technique to locate the seismic source, followed by cross-correlation
beamforming dispersion imaging. The dispersion images are highly analogous
to surface wave studies of pavements and display a complex multimodal
dispersion pattern. Supported by theoretical modelling based on a highly
simplified arrangement of horizontal layers, we infer that a ∼3.5–4.5 m thick, stiff, high-velocity layer overlies a ∼30 m
thick layer that is significantly softer and slower at our study site. Based
on previous studies we link the upper layer with syngenetic ground ice
formed in aeolian sediments, while the underlying layer is linked to
epigenetic permafrost in marine-deltaic sediments containing unfrozen saline
pore water. Comparing events from spring and autumn indicates that temporal
variation can be resolved via passive seismic monitoring. The transient
seismic events that we record occur during periods of rapidly changing air
temperature. This correlation, along with the spatial clustering along the
elevated river terrace in a known frost polygon, ice-wedge area and the high
proportion of surface wave energy, constitutes the primary evidence for us to
interpret these events as frost quakes, a class of cryoseism. In this study
we have proved the concept of passive seismic monitoring of permafrost in
Adventdalen, Svalbard.

Authors: Angeli Raquel , Fontana Maria Iolanda
Published: January 2021

O artigo discute a Avaliação Nacional de Alfabetização (ANA) no contexto das políticas educacionais de alfabetização e das avaliações em larga escala no Brasil. O objetivo é analisar as repercussões da ANA em ações político-pedagógicas adotadas pela Secretaria Municipal da Educação de Curitiba (SME), para a superação dos insuficientes níveis de leitura e escrita na sua rede de escolas. Trata-se de uma pesquisa quanti-qualitativa, que analisa resultados do INEP sobre a ANA e o conteúdo das entrevistas realizadas com coordenadores e pedagogos da SME. Conclui-se que a mantenedora reconhece como principal política para elevar a aprendizagem da alfabetização a formação continuada baseada nas Diretrizes Curriculares Municipais de Curitiba, justificando que os conteúdos coincidem com os aferidos pela ANA. Constata-se que a formação continuada não enfatiza a avaliação da aprendizagem articulada aos dados diagnósticos da ANA e às demandas político-pedagógicas do contexto escolar.

UM OLHAR FREIREANO PARA A BASE NACIONAL COMUM CURRICULAR DE MATEMÁTICA
Authors: Malheiros Ana Paula dos Santos , Forner Régis
Published: January 2021

Este artigo, de cunho teórico, tem por objetivo analisar e discutir a Base Nacional Comum Curricular (BNCC) e suas implicações no contexto educacional, a partir das ideias de Paulo Freire, com um olhar particular à Matemática, nossa área de atuação. Amparados no paradigma qualitativo, descrevemos de forma sucinta a trajetória da elaboração da BNCC até sua publicação, apresentamos um olhar freireano para Educação, para então analisar o ensino de Matemática proposto na BNCC. Esse movimento visa denunciar o que está posto e norteando o trabalho docente, e sulear caminhos que almejem contribuir com um processo de defesa da Educação e que possam romper com os pressupostos neoliberais presentes na BNCC. Nossas reflexões convergem em movimentos que suprimam a responsabilidade creditada exclusivamente ao professor, em detrimento às políticas públicas que envolvam outros entes da comunidade escolar. Por outro lado, entendemos que quando o professor tem a consciência do que está por trás da Base, pode contribuir para mudanças no contexto escolar.
INVESTIGAÇÃO TEMÁTICA FREIREANA E O ENFOQUE CTS NO ENSINO DE CIÊNCIAS: CURRÍCULOS E PRÁTICAS NO ENSINO FUNDAMENTAL
Authors: Schwan Guilherme , Santos Rosemar Ayres dos
Published: January 2021

Este relato é produto de uma pesquisa de mestrado desenvolvida no Programa de Pós-Graduação em Ensino de Ciências – Universidade Federal da Fronteira Sul. A temática surgiu da implantação de uma usina hidrelétrica no município de Roque Gonzales, RS. O objetivo constituiu em construir possibilidades de práticas escolares e colaborar junto à educação CTS e os pressupostos de Paulo Freire, contribuindo na interação de professores das disciplinas de Ciências e Geografia, com trabalhos concretos em sala de aula, com estudantes do 9º ano no Ensino Fundamental, em uma escola pública municipal situada no mesmo munícipio de implantação do empreendimento, utilizando questionários para a identificação de conteúdos, e como forma de contribuir na análise da prática, usamos diários de bordo com memórias do pesquisador e estudantes. Deste modo, procuramos estimular a participação docente no planejamento de aulas que tragam problemáticas reais da Ciência-Tecnologia e aos estudantes a emergirem de uma consciência ingênua para uma concepção crítica de sua realidade.
50 ANOS DA PEDAGOGIA DO OPRIMIDO: QUEM SÃO OS OPRIMIDOS HOJE?
Authors: MORAIS COSTA ANA MARIA , Cabral Marinho dos Santos Simone , Do Vale Elizabete Carlos
Published: January 2021

A provocação para dialogar sobre os 50 anos do livro Pedagogia do Oprimido comunga com o desafio de pensar a educação brasileira num contexto caracterizado como “tempo de incerteza”, instaurado no país desde 2016. De caráter teórico, discutimos nesse artigo, a pedagogia freriana que se reinventa na dinâmica da realidade social, encontrando inspiração e renovação ao longo dos anos. Uma pedagogia que se alimenta da transformação objetiva da condição de opressão e da ação dos sujeitos sociais sobre o mundo para transformá-lo. Daí, partimos da seguinte pergunta: Quem são os oprimidos hoje? Por ela, enveredamos o texto com reflexões sobre o contexto atual no Brasil e os desafios que se apresentam no “que fazer” como ponto crucial da ação educativa. Dessas reflexões, enfatizamos a atualidade do livro em questão e por que Paulo Freire continua incomodando, ao mesmo tempo que desperta o interesse e o compromisso sócio/político/educativo de educadores e ativistas sociais.
PENSAMENTO EDUCACIONAL FREIREANO: PERSPECTIVAS HUMANISTAS E LIBERTADORAS
Authors: Nakashima Rosária Helena Ruiz , Almeida Rejane Cleide Medeiros de , Cardoso Bruna da Silva
Published: January 2021

O pensamento educacional freireano nos mobiliza a refletir sobre educação dialógica, saberes docentes e metodologias de ensino problematizadoras, que nos inspiram a pensar, a sentir e a agir em busca da humanização, da vida e da libertação de homens e mulheres. O objetivo deste artigo é apresentar alguns matizes do pensamento de Paulo Freire, elucidando as perspectivas libertadoras e humanistas de sua pedagogia. Os resultados das reflexões apontam que conhecer, revisitar e/ou reinventar as ideias de Freire são práticas essenciais para aqueles que acreditam que a educação dialógica é fundamental para os processos de recriação de um mundo mais justo, inclusivo, acolhedor, generoso e sustentável.

Published: January 2021

Este texto tem por objetivo estabelecer um diálogo a partir de aproximações entre as ideias de dois pensadores importantes no contexto educacional contemporâneo: Paulo Freire e Edgar Morin. Eles são também contemporâneos na participação no universo social e político desses tempos. Outro objetivo é suscitar a reflexão com e na diversidade, privilegiando a educação como possibilidade de transformação da realidade. Esse estudo se realiza em momento propício para se pensar em caminhos para o enfrentamento de entraves na educação, na ciência, na economia, na política, decorrentes de grave pandemia que, só no Brasil, até agosto de 2020, já havia ceifado mais de 120 mil vidas. Destacamos da obra dos autores, aspectos como: politização do pensamento, amorosidade, esperança e utopia, considerando pontos de convergência. A metodologia é bibliográfica.

Enzymatic Treatment of Soft Jackfruit (Artocarpus heterophyllus) Pulp With Two Commercial Pectinases: Physical Properties and Viscosity Analysis
Authors: Queiroz Edinara Lacerda , De Almeida Tamires Bastos , Almeida de Souza Sílvia Maria , Acosta Martinez Ernesto
Published: January 2021

The aim of this study was to investigate the effect of enzyme hydrolysis of jackfruit pulp using two commercial pectinase enzyme solutions with different polygalacturonase activities. A 2³ factorial design, with three repetitions at the central point, was used to establish the optimal conditions of jackfruit pulp hydrolysis, evaluating the effect of time (20 - 100 min), temperature (30 - 60ºC) and enzyme concentration (0.01 - 0.09%). The dependent variables viscosity, yield, soluble solids content, color intensity, shade, and turbidity were the responses evaluated. Viscosity, color intensity, shade, and turbidity of the pulps were significantly influenced by all studied variables with the determination coefficients (R2) between 0.74 and 0.99. The lack of adjustment was not significant in the models that describe the previous properties. The highest enzyme concentration (0.09%) was the factor with the greatest influence on the studied responses, regardless of the pectinase type.
La parrhesía como modo de atender la crisis democrática actual
Authors: Bravo Jiménez Natalia Andrea
Published: January 2021

En el marco de una crisis democrática que ha hecho cuestionarnos la forma en que estamos llevando a cabo este sistema de gobierno, la presente investigaciónpretende retomar la vieja noción de la parrhesía griega como el ethos que debiera guiar el debate político, pero también como un principio que debe estar presente en aquellos que hacen filosofía. Un cruce entre la acción comunicativa habermasiana y las palabras de Vattimo acerca del rol de la filosofía nos ayudarán a elucidar cómo abordar esta crisis: desde la discusión política para llegar al consenso, que forzosamente debe estar alineado con este potente concepto de parrhesía.
Parrhesía y epimeleia heautou en la construcción del sujeto político
Authors: Ferrada Rau Rocío Nili
Published: January 2021

Este artículo se centra en el análisis hermenéutico focaultiano de cuatro nociones del pensamiento griego clásico: La Parrhesía o discurso veraz, la Paideia o educación, la Psicagogia o conducción de las almas, y por último la Epimeleia Heautou o el cuidado del sí mismo.

Se esboza que mediante el discurso verdadero un mentor conduce el alma de su discípulo en su propia construcción o transformación, emergiendo un sujeto político que será apto para gobernar las almas de los otros hombres, mediante la verdad, la ética y la política.
Parrhesía y necropolítica
Authors: Molnár-Gábor Ferenc Alajos
Published: January 2021

En este texto examinaremos la relación problemática entre parrhesía, necropolítica y víctima. Nuestro trabajo estará radicado en una examinación de la necropolítica y su íntima relación con el biopoder foucaultiano, sus resistencias y efectos. Una resistencia particular está contenida en la noción de parrhesía, la cual recibirá su respectiva modificación modal ante los efectos de la necropolítica bajo las circunstancias examinadas. Con lo anterior, nuestra intención sería retratar una teoría de "víctimas y parrhesía" bajo el contexto de lo necropolítico y la no–filosofía. Nos "serviremos" de la manera más ética posible de material visual, entablando unos respectivos límites teóricos.
Consideraciones éticas para una irrupción de las neurotecnologías en la esfera pública
Authors: Pizarro Contreras Roberto Plácido
Published: January 2021

El presente artículo tiene por objeto recoger una serie de consideraciones en el ámbito de las neurociencias que podrían entrar en conflicto con la ética procedimentalista del discurso de Habermas para la realización de su democracia deliberativa. Ellas dicen relación, principalmente, con la influencia e inevitabilidad de los sesgos cognitivos y las emociones en la ruptura del diálogo. Esto servirá al propósito de introducir la pregunta de hasta qué punto es legítimo intervenir, por la vía de procedimientos y dispositivos que institucionalicen la comunicación, el funcionamiento de la mente y con este el de las racionalidades comunicativas de los ciudadanos. La pregunta adquiere especial relevancia hoy, cuando ya hay empresas que, alentadas por los avances logrados por las neurotecnologías, aspiran al diseño de interfaces cerebro-ordenador que supriman la oralidad entre los agentes deliberantes y solucionen ex ante sus discrepancias mediante procesos robóticos que ponen en entredicho la continuidad de la autonomía personal, de la deliberación democrática y la racionalidad tal como les conocemos.
Integrar la incertidumbre
Authors: Sebastián Adrián Pradier
Published: January 2021

La crisis sanitaria por coronavirus ha traído consigo una atención inusitada por las respuestas filosóficas. Son destacables aquellas que conceden un valor negativo a la esperanza, como una disposición evitable a toda costa. Paradójicamente, existe un intenso debate y un alto ritmo de publicaciones sobre el concepto de esperanza y sus beneficios para la vida humana. Mi objetivo consiste en ofrecer un balance de las principales contribuciones de los últimos veinte años, con especial atención a la llamada “descripción estándar” y sus bases tomistas. Tras ello ofrezco tres conclusiones en torno a las bondades de la esperanza.
