Evidence of Plant-Soil Feedback in South Texas Grasslands Associated with Invasive Guinea Grass Independent of Soil Inoculation Method
Authors: Bowman Elizabeth A , Plowes Robert M. , Gilbert Lawrence E.
Published: July 2021

Purpose: Plant-soil feedback plays a strong role in plant community composition, but the effect of invasive Guinea grass, Megathyrsus maximus, on these processes remains unexplored. Here, we aim to provide a first look at plant-soil feedback (PSF) process in South Texas savannahs currently undergoing invasion by Guinea grass. Our two main questions are (1) how does the presence of the invasive M. maximus alter PSF compared to non-invaded grasslands and (2) are these results robust to inoculation method. Methods: Under greenhouse conditions, we assessed growth of Guinea grass and response of the native seed bank in soil collected from grasslands invaded by Guinea grass and native grasslands using two methods of soil inoculation: individual and pooled soil samples.Results: Guinea grass grown in soil from invaded grasslands grew taller and accumulated higher biomass than in soil from non-invaded grasslands. Plants grown from the native seed bank were more species rich and abundant in soil from non-invaded grasslands but had higher biomass in soil from invaded grasslands. Overall, these results were robust to differences in inoculation method.Conclusion: In South Texas savannahs, presence of Guinea grass is associated with changes in the direction of plant-soil feedback processes with negative feedback processes possibly contributing to species coexistence in non-invaded native grasslands while positive feedback processes appear to reinforce invasion by Guinea grass. Future work is needed to assign causality of these changes to Guinea grass itself and further explore the role plant-soil feedback has in Guinea grass invasion.

Authors: Shen De-song , Yan Chang , Liang Yu , Chen Kai-hua , Zhu Xiao-dong
Published: July 2021

Objective
The purpose of this study was to explore the prognostic value of circulating lymphocyte subsets in patients with nasopharyngeal carcinoma (NPC) before treatment and the impact of chemoradiotherapy on lymphocyte subsets.
Methods
934 patients with non-metastatic nasopharyngeal carcinoma were analyzed retrospectively. The percentage of circulating lymphocyte subsets was detected by flow cytometry and analyzed retrospectively. The correlation between lymphocyte subsets and prognosis was evaluated by the log-rank test and Cox proportional hazards model, and the differences of lymphocyte subsets before and after chemoradiotherapy was comparing by the paired t-test and Wilcoxon signed rank test.
Results
Univariate and multivariate analyses indicated that high CD19+ B lymphocytes (HR 0.705, 95%CI 0.519–0.958, P = 0.026) and CD4+ T lymphocytes (HR 0.560, 95%CI 0.331–0.946, P = 0.030) before treatment were independent favorable prognostic factors for overall survival (OS) and distant metastasis-free survival (DMFS) in NPC patients, respectively. After chemoradiotherapy, the percentage of CD3+ T lymphocytes, CD4+ T lymphocytes, CD4/CD8 ratio and CD19+ B lymphocytes decreased significantly, while the percentage of CD8+ T lymphocytes and NK lymphocytes increased significantly.
Conclusion
Patients with high CD19+B lymphocytes and CD4+T lymphocytes have a better prognosis, and perhaps the immune response can be improved to make the prognosis better by increasing the number of lymphocyte subsets. Chemoradiotherapy may reduce the immune function of patients with nasopharyngeal carcinoma.
Schottky diode temperature sensor for pressure sensor
Authors: Basov Mikhail
Published: July 2021

The small silicon chip of Schottky diode (0.8x0.8x0.4 mm3) with planar arrangement of electrodes (chip PSD) as temperature sensor, which functions under the operating conditions of pressure sensor, was developed. The forward I-V characteristic of chip PSD is determined by potential barrier between Mo and n-Si (ND = 3 × 1015 cm-3). Forward voltage UF = 208 ± 6 mV and temperature coefficient TC = -1.635 ± 0.015 mV/⁰C (with linearity kT <0.4% for temperature range of -65 to +85 ⁰C) at supply current IF = 1 mA is achieved. The reverse I-V characteristic has high breakdown voltage UBR > 85 V and low leakage current IL < 5 μA at 25 ⁰C and IL < 130 μA at 85 ⁰C (UR = 20 V) because chip PSD contains the structure of two p-type guard rings along the anode perimeter. The application of PSD chip for wider temperature range from -65 to +115 ⁰C is proved. The separate chip PSD of temperature sensor located at a distance of less than 1.5 mm from the pressure sensor chip. The PSD chip transmits input data for temperature compensation of pressure sensor errors by ASIC and for direct temperature measurement.

Authors: Kumar Samir , Taiga Taneichi , Namura Kyoto , Fukuoka Takao , Suzuki Motofumi
Published: July 2021

Surface-enhanced Raman spectroscopy (SERS)-based biosensors have recently been extensively developed because of their high sensitivity and non-destructive nature. Conventional SERS substrates are unsuitable for detecting biomolecules directly from human skin. As a result, significant effort is being put into developing a gel-type SERS sensor that can segregate and detect biomolecules due to differences in molecular transport phenomena in the gel. However, no comprehensive research studies on the transport processes of molecules in gels in gel-type SERS sensors have been reported. This paper reports the differences in the transport phenomena of different molecules based on the time change of SERS spectrum intensity. The Au nanorod array substrate was coated with HEC gel to prepare a sample cell to study diffusion. The SERS spectra of aqueous solutions of 9 types of molecules were measured using the prepared sample cells. The rate at which each molecule diffuses into the gel differs depending on the molecule. The time variation of the characteristic SERS peak of each molecule was investigated based on a one-dimensional diffusion model, and the diffusion coefficient D was calculated for each molecule. A comparative study was conducted on the relationship between the diffusion coefficient and the molecular weight and molecular size, and it was found that the larger the molecular weight and molecular size, the slower the diffusion, which is based on the molecular motion theory and the inhibitory effect of the gel substance.
African Trypanosomiasis in Young Female in North India - A Rare Case Report
Authors: Parwan Deepika , Kumar Ranjan , Aggrawal Sumit
Published: July 2021

Human African trypanosomiasis, also known as sleeping sickness, is a vector-borne parasitic disease. It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. They are transmitted to humans by tsetse fly (Glossina genus) bites which have acquired their infection from human beings or from animals harboring human pathogenic parasites. Tsetse flies are found just in sub-Saharan Africa though only certain species transmit the disease. We report a case of human African trypanosomiasis in a 28-year-old Indian female who had a travel history to sub–Saharan Africa, Uganda and she presented with a history of fever, body ache, headache, decreased oral intake, pain lower abdomen, swelling and discharge from forearm chancre since last 4-5 days. Peripheral smear showed heavy parasitemia by flagellated forms of Trypanosoma and the diagnosis of Trypanosoma brucei was given on Peripheral smear report. Serological testing was also done and a diagnosis of West-African trypanosomiasis was confirmed. The patient was successfully treated and made a good recovery. So West-African trypanosomiasis should be considered in the differential diagnosis with presentation of fever with chancre in every person with recent history of travel to African countries as it is universally fatal without treatment.

Published: July 2021

Xanthoma of bone is a rare disorder of bone which occurs due to cholesterol deposits in the bone. Clinically the patients usually present with pain or fracture of the affected bone. Radiologically it presents as a lytic lesion, often with cortical expansion or disruption. Xanthoma of bone is usually associated with hyperlipidemia but rare cases of non- hyperlipidemia xanthoma are also reported, termed as primary bone xanthoma. Here we present a rare case of a 46-year-old male who presented with pain and swelling in the right middle finger.  X ray showed lytic lesion in the proximal phalanx of right middle finger. Laboratory tests showed normal lipid profile. Bone biopsy and histological examination is necessary for diagnosis and to differentiate it from Rosai–Dorfman disease, Langerhans cell histiocytosis and fibrous/post traumatic dysplasia, malignant fibrous histiocytoma, or metastatic renal cell carcinoma. A diagnosis of primary bone xanthoma was made based on histology and immunohistochemistry. The fracture was treated surgically. The case report emphasises the role of histology in diagnosis of this rare clinical entity.

Published: July 2021

Background: Hospital environment can serve as an important reservoir and thus a critical element in the transmission of bacterial infections especially in critical care settings such as Surgical and new-born units. Contact with contaminated surfaces may lead to Hospital Acquired Infections (HAIs) among healthcare workers, visitors and patients. Further, HAIs may contribute to the spread of drug-resistant bacterial infections. This study sought to determine bacteriological characteristics and distribution in patient care environmental surfaces (Surgical and new-born units) at Mbagathi hospital Nairobi Kenya.

Methods: A total of 700 samples were obtained from different surfaces: beds, bedside tables, sink taps handle, door handles, nursery incubators, paediatric weighing scale and new-born resuscitation machine by means of repeated screens over a period of three months. Microbiological isolation and identification were done by following standard laboratory methods established at Aga Khan University Hospital. Antibiotic susceptibility testing was carried out by using Vitek 2 system.

Result: Five bacterial genera were isolated, S. Aureus was 3% (19/700), E. coli 0.9% (6/700), Acinetobacter species was 1.4% (10/700), Pseudomonas species 0.1% (1/700) and coagulase negative staphylococcus (CoNS)13.0% (88/700). Trimethoprim/Sulfamethoxazole and Benzylpenicillin were the most resistant antimicrobial agents while Oxacillin, Cefoxitin, Levofloxacin, Linezolid was most sensitive.

Conclusion: All S. aureus were methicillin sensitive (MSSA). Patient beds surfaces were the most contaminated among the selected items while the nursery incubator was the least contaminated.
Does the Adoption Process of Financial Technology in Africa Follow an Inverted U-Shaped Hypothesis? An Evaluation of Rogers Diffusion of Innovation Theory
Authors: Okoli Tochukwu Timothy , Tewari Devi Datt.
Published: July 2021

As the global financial system evolves towards a technology-enabled financial solution-Fintech, its implication to the future of the financial system becomes a policy concern. This study investigates non-linear/inverted U-shaped Fintech adoption process among a panel of 32 African countries spanning from 2002–2018. The study argues that Fintech adoption in Africa will continue to rise and not follow the inverted U-shaped process if sustained through greater trade openness. The dynamic system GMM techniques found a strong evidence for an inverted U- shaped adoption process for the 32 African markets and 24 frontier African markets but violated among the emerging (N = 3) and fragile (N = 5) groups. The first lag of Fintech compatibility and the contemporaneous levels of relativeadvantage, complexity, trial-ability and observe-ability were its main determinants. The study concludes that Fintech will be replaced with new innovations in future irrespective of possible sustainability strategy. The need to strengthen African financial markets’ innovativeness to have a competitive edge on Fintech’s replacement is stressed.
Is There Any Influence of Other Cryptocurrencies on Bitcoin?
Authors: Hossain Md. Jamal , Ismail Mohd Tahir
Published: July 2021

In recent years, cryptocurrency or virtual currency is becoming an essential medium of exchange in consumer and domestic trading. Nevertheless, the trading values of cryptocurrency compared to real money are very uncertain and can change dramatically. This article is aimed to assess the uncertainty or volatility of cryptocurrencies, mostly on Bitcoin. In the digital currencies market, Bitcoin is a widely accepted currency. Other digital currencies of the market may influence Bitcoin. For example, Ethereum, Litecoin, Zcash, Monero, Dash and Ripple have a positive impact on Bitcoin. Previous research only focuses on Bitcoin and other markets such as stock markets, energy markets, and exchange rates. However, here we focus on interlinkages and volatility dynamics within cryptocurrency markets by applying some econometrics models. In this article, we have shown that the relationship between Bitcoin and other currencies can be modelled in the ARCH, GARCH, VAR and MGARCH framework. Forecast values of the GARCH (3,3) model are given very close to the original data. VAR stability result shows that the model is stable. Using the CCC, VCC, and DCC of the MGARCH model on daily returns from 1st January 2017 to 15th March 2019, we found significant volatility and strong correlations between the variables.
Capital Structure and Performance: Examination of Managerial Ability as Moderating Role
Authors: Simamora Alex Johanes
Published: July 2021

The debate on capital structure contribution occurs in many studies of finance. This research aims to examine the moderating role of managerial ability on the effect of capital structure on firms’ performance. The research sample includes 383 manufacturing firms years listed on the Indonesian Stock Exchange. The capital structure is measured by the leverage variables. Managerial ability is measured by a manager-specific efficiency score. The analysis method uses firm and year fixed effect regression tests. Based on the result, higher debts can improve firms’ performance when higher managerial ability occurs. Managers with managerial ability can promote the debt benefits and mitigate the cost of the debt so that the use of debt can increase firms’ performance. This research provides new evidence that managerial ability can fill the gap of inconsistent previous findings of the relationship between capital structure and performance.
Capacidades locales para el desarrollo de los territorios rurales: un debate vigente
Authors: Barboza Arias Luis Miguel
Published: July 2021

El objetivo de este artículo es identificar elementos de análisis que permitan dar continuidad a la discusión crítica sobre la incorporación del enfoque orientado a las capacidades en políticas para el desarrollo de los territorios rurales, y ampliar la reflexión sobre sus efectos en la cotidianeidad de los actores locales. Desde la década de 1990, este enfoque comenzó a ser utilizado en instrumentos de política cuyo foco principal fue el de los problemas del desarrollo. Se adoptó una perspectiva institucionalista y de fuerte orientación normativa, que vincula a los actores sociales con la formación de habilidades productivas instrumentales, sin que existiera una problematización oportuna de los contextos y las realidades situadas. Algunos debates teóricos recientes sobre la diversificación de los medios de vida, el desarrollo territorial rural y las transiciones sostenibles, permiten repensar esta cuestión. La estrategia teórico-metodológica del artículo se enmarca en el método analítico de investigación social. Se utiliza el enfoque etnometodológico para repensar el rol del actor social en la configuración de la realidad. Este abordaje metodológico considera la centralidad del sentido en la comprensión intersubjetiva de los fenómenos sociales. En las consideraciones finales, se argumenta que la incorporación de perspectivas orientadas al actor puede facilitar el estudio de un conjunto distinto de fenómenos y realidades, lo que representa una forma de superar las debilidades analíticas identificadas hasta el momento. Un enfoque renovado de capacidades rurales debe informar al diseño y formulación de políticas públicas sobre formas novedosas de co-construcción del conocimiento que permitan problematizar las categorías analíticas tradicionales. Es preciso que dichas políticas conserven cierto grado de reflexividad y autocrítica en el diseño y la formulación de sus instrumentos y estrategias, de manera que la intervención planificada a que estos dan origen no acabe por instrumentalizar la racionalidad que las fundamenta, o restringiendo la agencia de las personas para construir, en libertad, el tipo de vida que valoran como digna de vivir.

De las Políticas Públicas a las realidades políticas. La insuficiencia discursiva y las limitaciones constitutivas del Estado Nación
Authors: Ferrer Araújo Nina
Published: July 2021

En el marco de esta distopía, a la que no solo nos ha condenado el virus de la Covid-19, sino también los vicios de sociedades globales extractivistas, me place la lectura de autores y autoras de este Sur Global que plantean posturas críticas y reflexivas, no solo frente a las Políticas Públicas sino incluso, frente a las posibilidades del Estado. De esta manera, este número de la Revista Internacional de Cooperación y Desarrollo puede ser leído en cualquier orden; sin embargo me atrevo a recomendarles tal cómo lo comprendí: una primera parte que presenta análisis de casos particulares de Políticas o programas públicos, ricos en particularizaciones y contextos, y una segunda parte, más conceptual que incluso llega a visiones más integrales del Estado.

The authors conducted a prospective cohort study in 2018-2020 with the participation of 61 children aged 3–4 years with recurrent broncho-obstructive syndrome. Inclusion criteria: age 3–4 years; ≥ 3 episodes of broncho-obstructive syndrome in the past 12 months; informed voluntary consent. At the first visit the scientists determined the levels of serum periostin, specific inhalation allergens IgE, total IgE and the number of eosinophils in the blood. In 24 months, at the second visit, bronchial asthma was diagnosed based on the GINA criteria (updated 2019). Binary logistic regression analysis was used to study the predictors of bronchial asthma development.Results. In 24 months from the beginning of the study, bronchial asthma was diagnosed in 29 (47%) children with recurrent broncho-obstructive syndrome. The level of serum periostin and total IgE had no effect on the risk of developing bronchial asthma (p=0,194; p=0,269). According to binary logistic regression, the predictors of bronchial asthma development are burdened family allergic history (odds ratio – OR 3,81; 95% confidence interval – CI 1,14-12,74; p=0,015), allergic rhinitis (OR 4,94; 95% CI 1,37–7,80; p=0,0001), sensitization to the Dermatophagoides pteronyssinus (OR 1,80; 95% CI 1,36–1,13; p=0,045) and eosinophilia (OR 2,10 ; 95% CI 1,23-4,83; p=0,055).Conclusion. A burdened family allergic history, the presence of allergic rhinitis, sensitization to the Dermatophagoides pteronyssinus, eosinophilia are the predictors of bronchial asthma development in children with recurrent broncho-obstructive syndrome by 5-6 years of age.

Takotsubo syndrome (stress-induced cardiomyopathy) is well known in adult cardiology practice, and it also occurs in children. Takotsubo syndrome develops after emotional or physical stress. There is an acute transient disorder of the left ventricle contractility of the apex. The development of pain syndrome, electrocardiographic changes and troponins elevation imitate myocardial infarction. The key diagnostic point is intact coronary arteries and complete reversibility of local contractility disorders over the time.The article describes the clinical case of takotsubo syndrome in an adolescent with type III spinal muscular atrophy after planned surgery (repeated posterior spondylodesis).Takotsubo syndrome with clinical manifestations of acute left ventricular failure and pulmonary edema developed in the early postoperative period with distinctive electrocardiographic changes (ST segment elevation, local impairment of left ventricular contractility according by echocardiography and ventriculography, and increased levels of troponin). Timely examination and correction of therapy confirm the clinical diagnosis. The regression of symptoms occurred within a few days.

Authors: Mubtadi Novendi Arkham , Setiawan Eka Riyani
Published: July 2021

The purpose of this study is to examine the effect of deferred tax expense, tax planning, and managerial ownership on earnings management moderated by institutional ownership in manufacturing companies listed on the Indonesia Stock Exchange (IDX) in 2015-2018. The number of research samples is 16 companies. The sampling technique used in the study is purposive sampling method. This study uses multiple linear regression analysis and Moderated Regression Analysis (MRA) assisted by the IBM SPSS 24 program. The results of this study show that deferred tax expense and managerial ownership haveno effect on earnings management, while tax planning has an effect on earnings management. Institutional ownership is not able to moderate the effect of deferred tax expense and managerial ownership on earnings management, but institutional ownership is able to moderate the effectof tax planning on earnings management. The limitation of this study is that the measurement technique used for earnings management is only accrual earnings management. In addition, researchers do not measure earnings management from real earnings management techniques so that the results obtained cannot explain the extent of deviations from normal business practices. The results of this study are expected to provide considerations for potential investors who wish to invest in a company so that they do not experience losses on their invested capital. Company managers are expected to be able to reconsider everything so that there will be no more fraud that can cause losses to the company and have a bad impact in the future.

Published: July 2021

This study aims to determine the effect of corporate governance, risk management, and compliance with applicable regulations on efforts to minimize the potential fraud based on the Fraud Pentagon concept. For companies engaged in financial service providers, the results of this study are expected to contribute to the implementation of governance, risk management, and compliance (GRC) in order to minimize potential fraud and achieve the expected goals. Respondents used in this study are the employees of Bank Perkreditan Rakyat (BPR). Data are collected using interviews, observations, and questionnaires. Descriptive analysis, data quality analysis, and structural model analysis are used to test hypotheses with the application of STATA version 14. The results show that the variables of corporate governance and risk management have a significant effect on the efforts to minimize potential fraud, while the variable of compliance has no significant effect on the efforts to minimize potential fraud. Due to several factors, such as the small scope of BPR compared to conventional banks and the small number of employees, the implementation of GRC has not been achieved optimally.
Characteristics Affecting Anti-corruption Behavior in Indonesia
Authors: Kosasih Ahmad
Published: July 2021

The problem of corruption in Indonesia at this time is nothing new in the midst of Indonesian people. Low integrity and permissive culture of corruption are suspected to be the cause of the development of corrupt practices. The Indonesia Anti-Corruption Behavior Index (ACBI)) compiled by Statistics Indonesia (Indonesia: BadanPusatStatistik / BPS) is used to obtain a complete picture of the current situation and conditions of community anti-corruption behavior. This study aims to determine the characteristics that differentiate Anti-Corruption Behavior Index (ACBI)scores. The analytical method used is descriptive and non-parametric analysis to determine differences in ACBI seen from other dimensions and characteristics such as residential area, education level, and age group. In general, ACBI in Indonesia has continued to increase from 2012 and reached the highest moment in 2020, amounting to 3.91 in the category of very anti-corruption. The dimensions and characteristics of the area of residence and the level of education have significant differences in ACBI, while the age groups do not have differences in ACBI. Policies in an effort to improve anti-corruption behavior of the community need to pay attention to dimensions and characteristics that have significant differences so that the policies implemented can be right on target.
Households' reluctance to collect potable water from improved sources, Ethiopia
Authors: Addisie Meseret B. , Gelaye Tesfaye Y. , Teshome Wondie M.
Published: July 2021

Water resources development and management are central to economic growth and poverty reduction. Despite considerable efforts, many households still rely on unimproved water sources. This research aimed to understand the reasons behind household reluctance to collect potable water from improved sources in urban and rural settings. Sixteen water points were selected purposively and a household survey conducted on the selected improved water source users. The result shows that in the urban areas people were satisfied with the water services provided. However, the poor could not afford the high cost of water and households sought unprotected alternative sources. Seventy-seven per cent of the urban and 65% of the rural households collect water from unimproved sources. Family size was the determinant factor for household water consumption from improved sources. Reliability, queuing time, high quality, and distance were associated with households' reluctance to collect potable water from improved sources. In conclusion, households' dependency on unprotected sources had a direct impact on the sustainability of schemes. Social factors are also fundamental when thinking about the sustainability of schemes.

Published: July 2021

Los quitones son un grupo de moluscos muy comunes en el mar de la costa Caribe colombiana. No obstante, los estudios respecto a estos organismos y el seguimiento a sus poblaciones son escasos, por lo que el objetivo de la investigación fue determinar la abundancia de la población de quitones y su morfometría en el municipio de Coveñas, Sucre. Se realizaron muestreos mensuales entre marzo y agosto del 2015. Con ayuda de un cuadrante de 1 m2, se contabilizaron los individuos presentes en la zona semisumergida de los rompeolas. Adicionalmente, se recolectaron quitones para medir características morfométricas: largo, ancho y peso. Se identificaron tres especies: Acanthopleura granulata, Chiton tuberculatus y C. marmoratus. Se contabilizaron 2529 individuos (10,62 ind/m2) siendo la especie más abundante A. granulata, con 1758 individuos (7,32 ind/m2), mientras la menos abundante fue C. marmoratus con 45 individuos (3,02 ind/m2). El mes con mayor densidad fue junio con 12,45 ind/m2, mientras agosto tuvo la menor (8,80 ind/m2). No se encontraron diferencias significativas entre las especies de acuerdo con las variables morfométricas evaluadas. Las masas estimadas en este estudio son los primeros registros para estas especies en Colombia. La población de quitones evaluada en Coveñas parece estar en buen estado, debido al mantenimiento de su abundancia en comparación a estudios anteriores en la zona. El comportamiento temporal observado coincide con el encontrado en otras zonas del Caribe.

O olhar dos formadores acerca do trabalho realizado nas instituições de educação infantil
Authors: Fernandes Juliana Gonçalves Diniz
Published: July 2021

Apesar da atual legislação alocar a Creche como uma etapa inicial do sistema educacional brasileiro, esta instituição ainda é representada socialmente como um espaço voltado ao atendimento das necessidades da mãe trabalhadora, no qual as atividades desenvolvidas estão associados à maternagem e à puericultura. Considerando que estes profissionais devem buscar sua formação junto aos cursos de magistério e pedagogia, estudamos, através de entrevistas abertas feitas com seis professoras de cursos de magistério e pedagogia, qual a compreensão que estas formadoras têm a respeito do trabalho do educador de creche. A análise das falas das formadoras foi feita a parir de categorias: concepção e idealização de creche; concepção e idealização de educador de creche; contribuições dos cursos de magistério e pedagogia para a formação dos educadores de creche; relações creche e famílias.

Abstract:

Despite the current legislation allocates the “Creche” (daycare, day nursery) as an initial stage of the Brazilian educational system, the institution is still socially represented as a place dedicated to the needs of the working mother, in which the activities carried out are associated with the motherhood and childcare. Whereas these professionals must seek their training in the courses of “magistério” and teaching pedagogy, we carried out this survey through open interviews made with six teachers of “magistério” and teaching pedagogy courses, by asking their understanding of the work of the daycare educator. The analysis of the discourse was made by the following categories: concept and idealization of daycare; concept and idealization of educator, nursery; contributions of “magistério” and teaching pedagogy courses for daycare educators, daycare; relationship between day nursery and families.
Formação de professores de espanhol no brasil e as novas(?) Formas de ensino-aprendizagem à distância
Authors: Soto Ucy
Published: July 2021

Tomando como ponto de partida o imaginário social (Hurtato Herrera, 2004) sobre língua espanhola, apresentamos uma discussão sobre a formação de professores de espanhol no Brasil e, especificamente, nos perguntamos o que muda e o que permanece no ato de ensinar-aprender espanhol com a incorporação de TICs. Com base nos trabalhos de Dabène (1984) e de Carmagnani (2006), apresentamos uma análise em fase inicial de três diferentes formas/suportes para se trabalhar o ensino-aprendizagem de espanhol à distância, a saber: um cd-rom interativo, um curso on-line e uma plataforma de aprendizagem sem conteúdo pré-definido.
Martin buber: uma alternativa para se pensar as inter-relações no cotidiano escolar
Authors: Arruda Márcia R. M.Ferraz , Badia Denis Domeneghetti
Published: July 2021

Nesta comunicação procuramos mostrar a propriedade das idéias de Martin Buber, na obra Eu e Tu (2001), para se pensar as inter-relações na escola. Em termos antropológicos, no cotidiano escolar se configuram, simultaneamente, cultura organizacional e a cultura de grupos, segundo Edgar Morin (1984) e Michel Maffesoli (1998). Buscamos na “filosofia do encontro” uma reflexão sobre as relações inter-subjetivas produzidas pelos sujeitos no cotidiano escolar. São relações que efetivam a comunicação, definida por Buber como um encontro, no qual se dá a complementaridade e reciprocidade das ações entre o Eu-Tu, o dialógico, em detrimento à experiência de contato proporcionada no Eu-Isso, o monológico. A questão a ser iluminada diz respeito ao fato de que, por meio da “filosofia do encontro”, talvez possamos encontrar suportes teóricos consistentes para repensarmos as relações produzidas pelos sujeitos no âmbito escolar, o que evidencia o caráter “ontológico” de uma questão crucial na escola: ensino-aprendizagem.

Abstract:

This paper will attempt to point out relevance of the ideas of Martin Buber, in the work “I and Thou” (2001), to think the interrelations in school. In anthropological terms, in the school daily life both organizational culture and the culture of groups are established, according Edgar Morin (1984) and Michel Maffesoli (1998). We searched on the “Philosophy of the Meeting" a reflection on the inter-subjective relations produced by the subjects in the everyday life school. They are relations that implement the communication, defined by Buber as an encounter, which gave the complementarity and reciprocity of actions between the “I-Thou”, the dialogical, to the detriment of the experience of contact provided in the “I-That”, the monological. The issue to be enlightened relates to the fact that, through the "philosophy of the meeting," perhaps we can find consistent theoretical support in order to rethink relations produced by subjects within the school, which shows the "ontological" character of a crucial issue in school: teaching-learning.
Material didático e prática docente
Authors: Fiscarelli Rosilene Batista de Oliveira
Published: July 2021

O presente trabalho objetiva discutir o discurso docente acerca dos materiais didáticos, a partir da análise das práticas discursivas construídas pelos professores em torno desses objetos no ensino, apoiando-se nos estudos foucaultianos sobre discurso e construção de conhecimento. Os dados analisados durante a pesquisa foram coletados a partir de entrevistas com professores da rede pública de ensino paulista. Os resultados das análises realizadas conduzem-nos a pensar um pouco mais sobre esses materiais no cotidiano escolar; na maneira como os professores concebem esses materiais e apropriam-se deles em sua prática docente; nas implicações que surgem ao introduzir-se materiais no ensino e nas maneiras e possibilidades de preparar os professores para essas implicações. Ao compreendermos os materiais didáticos no processo de desenvolvimento profissional do professor, abrimos possibilidades de superação de obstáculos que venham inibir o espaço de experimentação e o crescimento profissional a partir da utilização desses materiais em sala de aula.
Escola e violência: análise da produção academica sobre o tema na área de educação no período de 1990 a 2005.
Authors: Zechi Juliana Aparecida Matias
Published: July 2021

A presente pesquisa objetiva avaliar as tendências teórico-metodológicas da produção acadêmica com relação aos temas de violência e indisciplina escolar, verificar como essas temáticas têm sido analisadas e explicadas e quais metodologias estão sendo utilizadas para seu estudo e analisar as proposições apresentadas com a finalidade de prevenção e contenção da violência e indisciplina. Para sua realização fizemos levantamento bibliográfico de estudos sobre essas temáticas publicadas em periódicos científicos no período de 1990 a 2003 e produzidos em Programas de Pós-graduação em Educação do Estado de São Paulo de 2000 a 2005. Apresentaremos aqui os resultados da análise dos periódicos. Percebemos nos artigos analisados, que a violência e indisciplina escolar têm sido estudadas tanto como um dos fatores que refletem a violência social, como um fenômeno que nasce no interior da escola e em decorrência de práticas escolares inadequadas. Os autores apresentam iniciativas de cunho educativo voltadas para a prevenção e enfrentamento do problema nas escolas.
