Electron Matter-Waves as Electromagnetically Induced Crystal Oscillator Effects
Authors: Hazani Joseph A
Published: April 2021

The famed Davisson-Germer Experiments demonstrated the wave phenomenon of electrons similarly to X-Ray scattering from Sir Lawrence Bragg’s X-ray experimentations on crystals c. 1913. Their empirical deduction of electrons behaving as waves (i.e. oscillatory) ignores the possibility of an electron beam behaving harmonically upon elastic collision with a diffraction grating - represented by nickel crystal - in their experiment. However, it is well established in the electrical engineering science that crystals possess piezoelectric effects and are used ubiquitously in electronic circuit designs for causing stable harmonic oscillation responses to direct current voltages. In light of this, the current mathematical model proposes the Davisson-Germer results to be the effect of a nickel crystal oscillator circuit which amplifies a direct voltage source – the electron beam – causing the phenomenon of inductance from the resultant electrical feedback with the crystal atom’s electromagnetic field.

Background: Post-traumatic Stress Disorder (PTSD) is a significant public health problem, affecting approximately 7% of the general population and 13 – 18% of the combat Veteran population. The first study using acupuncture for PTSD in a civilian population showed large pre- to post-treatment effects for an empirically developed verum protocol, which was equivalent to group cognitive behavior therapy and superior to a wait-list control. The primary objective of this study is to determine both clinical and biological effects of verum acupuncture for combat-related PTSD in treatment-seeking U.S. Veterans.Methods: This is a two-arm, parallel-group, prospective randomized placebo-controlled clinical trial. The experimental condition is verum acupuncture and the placebo control is sham (minimal) acupuncture in 1-hour sessions, twice a week for 12 weeks. Ninety subjects will provide adequate power and will be allocated to group by an adaptive randomization procedure. The primary outcome is change in PTSD symptom severity from pre- to post-treatment. The secondary biological outcome is change from pre- to post-treatment in psychophysiological response, startle by electromyographic (EMG) eyeblink. Assessments will be conducted at pre-, mid-, post-, and 1-month post-treatment, blind to group allocation. Intent-to-treat analyses will be conducted.Discussion: The study results will be definitive because both clinical and biological outcomes will be assessed and correlated. Issues such as number needed for recruitment and improvement, use of sham acupuncture, choice of biological measure, and future research need will be discussed.Trial registration: ClinicalTrials.gov ID: NCT02869646

Published: April 2021

2019 was Earth's second warmest year since 1850. In 2019 the global mean temperature was cooler than in 2016, but warmer than any other year explicitly measured. Consequently, 2016 is still the warmest year in historical observation history. Year-to-year rankings are likely to reflect natural fluctuations in the short term, but the overall pattern remains consistent with a long-term global warming trend. This would be predicted from global warming caused by greenhouse gases, temperature increase across the globe is broadly spread, impacting almost all areas of land and oceans. Climate change" and "global warming" are often used interchangeably but are of distinct significance. Global warming is the long-term heating of the Earth's climate system observed since the pre-industrial period as a result of human activities, mainly the combustion of fossil fuel, which raises the heat-trapping greenhouse gas levels in the Earth's air. The term is often used interchangeably with the term climate change, as the latter applies to warming caused both humanly and naturally, and the impact it has on our planet. This is most generally calculated as the average increase in global surface temperature on Earth. Carbon dioxide emission is one of the main reasons for global warming. Since the Industrial Revolution, human sources of carbon dioxide emissions have been growing. Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere. In our research, let’s examine the relationship between the amount of carbon dioxide emissions and the GDP/capita in developed and developing countries.

Published: April 2021

The aim of the study is to develop protocols for the treatment and prevention of generalized periodontal disease using a nozzle that designed for transgingival photosensitizer activation.
Methods. Analysis of available variants of irradiation nozzles for photoactivated disinfection. Circuit design and construction of authors’ irradiation nozzle for transgingival photosensitizer activation.
Results. Based on the analysis of data, there was developed a nozzle design that allows treating periodontium areas within 4-6 teeth, evenly distributes the required power of laser radiation, and can be used in hard-to-reach areas of the oral cavity. Based on the above calculations, a nozzle for transgingival photosensitizer activation was created (jointly with Fotonika Plus, PE). To optimize the PAD procedure, there was created a protocol of transgingival photoactivated disinfection to be applied at the stage of professional oral hygiene, using the created irradiation nozzle NOU-9 of authors’ design, and diode 2 W laser LIKA-surgeon with a wavelength of 660 nm. The result is the accelerated procedure of transgingival photoactivated disinfection.
Conclusions. The development of photoactivated disinfection technology allows supplementing the traditional treatment of generalized periodontal diseases. Studies of non-invasive, transgingival method of photosensitizer activation have recently become popular. This, in turn, carries a lower probability of cross-infection and less traumatization of periodontal tissues during the manipulation. The use of PAD cannot lead to resistance of the microflora in contrast to pharmacological antibacterial preparations. Carrying out PAD does not require any complex manual skills, the purchase of expensive equipment, provides an opportunity for widespread introduction of technology. The use of the therapeutic complex and protocols of PAD that were developed can significantly reduce the duration of the procedure, resulting in improved comfort for both the doctor and the patient. The NOU-9 irradiation nozzle allows reaching hard-to-reach areas of the oral cavity, distributing laser radiation efficiently and evenly on periodontal tissues. The LIKA-surgeon 2 W laser with a wavelength of 660 nm provides the operating parameters required to activate the photosensitizer. Due to low-intensity radiation, it is possible to enhance regenerative processes in the periodontium after traumatic intervention. Clinical studies on the antibacterial efficacy of the technology are ongoing

The aim of the study was to conduct a comparative analysis of fibroblast growth factor-2, the total content and fractions of sulfated glycosoaminoglycans as well as free and peptide-bounding oxyproline as the markers of connective tissue metabolism in young patients with mitral valve prolapse, type 1 diabetes mellitus and the combination of both indications.
Materials and methods. 93 patients between 19 and 33 years old with either mitral valve prolapse, or type 1 diabetes or the combination of both indications were examined. Group 1 was represented by 36 patients with the monomorbid type 1 diabetes mellitus. Group 2 consisted of 33 patients with type 1 diabetes mellitus and mitral valve prolapse. The comparison group included 24 people with diagnosed mitral valve prolapse. The concentration of fibroblast growth factor-2 in blood plasma was determined by the enzyme immunoassay using a Quantikine reagent kit (Human FGF basic Immunoassay), manufactured by R&D Systems, Inc. (USA) and expressed in pg/ml. The total content and fractions of glycosaminoglycans in blood serum were determined by the method of N. G. Stern et al. and expressed in units of optical density. The level of free and peptide-bounding oxyproline in blood serum were determined by the method of P. N. Sharaev and expressed in µmol/L.
Results. Fibroblast growth factor-2 was higher in group 2, where it was 23.7±0.25 pg/ml compared to the control group – 14.20±0.22 pg/ml (p <0.01). There was also a significant difference in the levels of fibroblast growth factor-2 between groups 1 where it equaled 15.33±0.24 pg/ml and 2 – 23.71±0.25 pg/ml (p<0.01). The total content of glycosaminoglycans in comparison with the control group, where it was equal to 9.7±0.62 odu, was higher in all groups of patients: in group 1 it was 12.07±1.04 odu, in the comparison group it was 11.75±0.83 odu, in the group with the combined pathology it was 13.32±1.59 odu (p<0.05). The values of glycosaminoglycans II fraction, were higher in group 2 – 4.96±0.59 odu. The level of peptide-bound oxyproline, just as the level of free oxyproline, significantly increased in patients with comorbid pathology in group 2, compared to the control group: 16.06±1.54 µmol/l versus 8.7±0.81 µmol/l (p<0.01) respectively.
Conclusions. The values of fibroblast growth factor-2, glycosaminoglycans II fraction, free and peptide-bound oxyproline were significantly higher in patients with diabetes mellitus and mitral valve prolapse in comparison with the control group. Fibroblast growth factor-2 was higher in patients with comorbid pathology compared to the monomorbid diabetes patients.

In this study, we assessed the cytotoxic effect of 1,3-diphenyl-2-allyl-1,3-propanedione (DPAP) on B16F10 and Tm5 melanoma cells and investigated its interaction with DNA (deoxyribonucleic acid) using optical tweezers. The compound showed to be effective against B16F10 cells with selectivity index (SI) of 7.92 and interaction to the outer surface of the double helix, probably at the minor groove of DNA. This likely induced a bending deformation of the polymer chain, decreasing persistence length, and indicated that each DPAP molecule occupies a single base pair upon binding to the double helix.

Published: April 2021

To evaluate the antibacterial efficacy of hotodynamic Therapy (PDT) in root canal (RC) disinfection. An integrative review of the literature was performed in diferents databases. It was selected articles published between January 2014 and January 2018, in Portuguese, English or Spanish languages, which evaluated, in a clinical trial, the antibacterial efficacy of PDT in RC disinfection. The sample consisted of 05 articles that met all the inclusion criteria, which analyzed aspects such as: sample; photosensitizer and exposure time; light source, wavelength, potency, energy and time of emission; and results. Most of the studies used single-rooted teeth and methylene blue photosensitizer with pre-irradiation time ranging from 1 to 5 minutes. The LED and the laser were the light sources used, with exposure time ranging from 40 to 240 seconds; power from 60 mW to 1000 mW; power density from 2 to 4 mW / cm2; energy of 4 to 9,6 J; and dose from 1.2 mJ / cm2 to 129 J / cm2. It can be concluded that, despite the heterogeneity of the protocols, there was a reduction in the bacterial populations responsible for RC infections, and it may be a supporting technique in endodontic therapy.
Quantifying the potential impacts of land-use and climate change on hydropower reliability of Muzizi hydropower plant, Uganda
Authors: Bahati Hilary Keneth , Ogenrwoth Abraham , Sempewo Jotham Ivan
Published: April 2021

Ugandan rivers are being tapped as a resource for the generation of hydropower in addition to other uses. Studies on the reliability of these hydropower plants due to climate and land-use/land cover changes on the hydrology of these rivers are scanty. Therefore, this study aimed to model the impact of the changing climate and land-use/cover on hydropower reliability to aid proper planning and management. The hydropower reliability of Muzizi River catchment was determined from its past (1998–2010) and midcentury (2041–2060) discharge at 30 and 95% exceedance probability under Representative Concentration Pathways (RCPs) of 4.5 and 8.5, respectively. The past and projected hydropower were compared to determine how future climate and land-use changes will impact the discharge and hydropower reliability of Muzizi River catchment. Six LULC scenarios (deforestation, 31–20%; grassland, 19–3%; cropland, 50–77%; water bodies, 0.02–0.01%; settlement, 0.23–0.37%, and Barren land 0.055–0.046% between 2014 and 2060) and three downscaled Regional Climate Model (REMO and RCA4 for precipitation and RACMO22T for temperature from a pool of four CORDEX (Coordinated Regional Climate Downscaling Experiment) Africa RCMs) were examined. A calibrated SWAT simulation model was applied for the midcentury (2041–2060) period, and a potential change in hydropower energy in reference to mean daily flow (designflow ≥ 30% exceedance probability), firm flow (flow ≥ 95% exceedance probability), and mean annual flow was evaluated under the condition of altered runoff under RCP4.5 and RCP8.5 climate change scenarios for an average of REMO and RCA4 RCM. The future land use (2060) was projected using the MOLUSCE (Module for Land Use Change Evaluation) plugin in QGIS using CA-ANN. Three scenarios have been described in this study, including LULC change, climate change, and combined (climate and LULC change). The results suggest that there will be a significant increase in annual hydropower generation capacity (from 386.27 and 488.1 GWh to 867.82 and 862.53 GWh under RCP4.5 and RCP8.5, respectively) for the combined future effect of climate and land-use/cover changes. Energy utilities need to put in place mechanisms to effectively manage, operate, and maintain the hydropower plant amidst climate and land-use change impacts, to ensure reliability at all times.
Study on association solubilization and inhibition of scale in recirculating cooling water system under S-HGMF
Authors: Zhao Xin , Li Suqin , Han Shuaishuai , Jin Jianjiang , Zhang Peng
Published: April 2021

The present study conducted an investigation on the effect of a superconducting high gradient magnetic field (S-HGMF) on the association solubilization of recirculating cooling water and the crystal form change of scale. The effects of magnetic flux density, flow rate and cycle-index on the solubility of scale-forming ions were investigated, and the effects of viscosity and surface tension on the molecular internal energy and order degree of the circulating water were analyzed. The scale was ground and mixed with water and placed in an S-HGMF system to study the effect of S-HGMF on the crystal form change of CaCO3. The experimental results showed us that S-HGMF could increase the solubility of scale-forming ions. It could enhance the interaction between water molecules by increasing viscosity and reducing surface tension, so as to improve the stability of water quality, reduce ion precipitation, and achieve the effect of scale inhibition. At the same time, it could also change the crystal structure of CaCO3, promote the transformation of calcite to aragonite, and realize the purpose of scale inhibition. In a word, S-HGMF treatment can effectively solve the scaling problem of a recirculating cooling water system, which provides a reference for scale inhibition of recirculating cooling water.
Sleep, Narcolepsy, and Sodium Oxybate
Authors: Mamelak Mortimer
Published: April 2021

:

Sodium oxybate (SO) has been in use for many decades to treat narcolepsy with cataplexy. It functions as a weak GABAB agonist but also as an energy source for the brain as a result of its metabolism to succinate and as a powerful antioxidant because of its capacity to induce the formation of NADPH. Its actions at thalamic GABAB receptors can induce slow wave activity while its actions at GABAB receptors on monoaminergic neurons can induce or delay REM sleep. By altering the balance between monoaminergic and cholinergic neuronal activity, SO uniquely can induce and prevent cataplexy. The formation of NADPH may enhance sleep’s restorative process by accelerating the removal of the reactive oxygen species (ROS) which accumulate during wakefulness. SO improves alertness in patients with narcolepsy and in normal subjects. SO may allay severe psychological stress - an inflammatory state triggered by increased levels of ROS and characterized by cholinergic supersensitivity and monoaminergic deficiency. SO may be able to eliminate the inflammatory state and correct the cholinergic/ monoaminergic imbalance.

Published: April 2021

Problem statement. During operation, stationary large-aperture digital antenna arrays (DAA) are affected by climatic factors, including snow and ice cover. This influence inevitably leads to distortion of the amplitude-phase distribution (APD) of the field at the DAA aperture, which makes it necessary to consider and compensate for these factors on the APD of the antenna array field.Objective. Development of a more technically simple and precise method for compensating for APD field distortions at the aperture of a stationary large-aperture DAA caused by the influence of climatic factors of snow and ice cover.Results. The article analyzes the influence of climatic factors of snow and ice on the distortion of the APD field at the DAA aperture. The dependence of the power reduction of the probing signal on the thickness of the snow and ice layer at the aperture is obtained. The correction method of APD field distortions caused by climatic factors’ influence is developed, which is characterized by simplicity of technical implementation and higher accuracy of correction of distortions. A technical realization of the method of correction of distortions of the APD field is proposed.Practical implications. The developed method can be used at the stages of creation and operation of stationary large-aperture DAAs, taking into account the influence of climatic factors of snow and ice cover on the field APD.

Published: April 2021

Problem statement. In measuring the spatial coordinates of sources of active interference, one of the main tasks is to identify their bearings. This problem belongs to the class of multi-alternative problems of statistical choice of hypotheses, the solution of which becomes much more complicated with an increase in the number of sources of active interference.Objective. Reduce the prior uncertainty in identifying bearings of active interference sources due to the use of differences in their energy characteristics at the stage of primary processing of interference signals, recalculated to the points of intersection of bearings.Results. The article discusses the processing features of bearing information in a two-position radar system. It is shown that in these systems, due to the absence of redundant information, the identification of bearings is a multi-alternative problem of statistical choice of hypotheses. The analysis of the matrix of coordinates of intersections of azimuthal bearings is carried out, a rule for identifying possible hypotheses of identification is formulated. It is proposed to use the energy differences of interference signals to reduce the prior uncertainty in identifying bearings. It is shown that a measure of this difference can be the value of the correlation integral, calculated at the stage of primary processing of interference signals.Practical implications. The principle of bearing identification considered in the article can be used to implement the identification of bearings from sources of active interference and other various radio emission objects, including space ones, when upgrading the mathematical and software systems for information processing.

Zaproponowane sieciowe produkty turystycznych są próbą przezwyciężenia problemu, jakim jest brak integracji pomiędzy ofertą turystyczną Warszawy a walorami dotychczas niewykorzystanymi w subregionach: siedleckim, radomskim, płockim, ciechanowskim i ostrołęckim. Rozwój turystyki poprzez komercjalizację tych usług jest jedną z możliwości ożywienia społeczno-gospodarczego ww. subregionów. Funkcjonowanie produktów turystycznych wymaga ciągłego zaangażowanie liderów i partnerów oraz wsparcia merytorycznego i finansowego ze strony administracji samorządowej województwa i organizacji turystycznych, w tym Mazowieckiej Regionalnej Organizacji Turystycznej. Celem artykułu jest charakterystyka trzech, spośród ww. 16, sieciowych ofert turystycznych: Wielki Gościniec Litewski, Mazowiecka Micha Szlachecka i Kraina Mistrza Twardowskiego funkcjonujących w subregionie siedleckim. W artykule przedstawiono działania promocyjne i organizacyjne podejmowane na rzecz rozwoju takich usług sieciowych i ich umocnienia na rynku turystycznym, na przestrzeni ostatnich 5 lat. Intensywność działań osób zaangażowanych w tworzenie ww. ofert stanowiła podstawę do zakwalifikowania ich przez MROT do grupy produktów najbardziej zaawansowanych w komercjalizacji.
Kurpiowszczyzna w badaniach naukowych Cykl: Kurpiowszczyzna. Przekształcenia krajobrazu osadniczego do czasu przystąpienia Polski do Unii Europejskiej
Authors: Starzyk Agnieszka
Published: April 2021

Kurpiowszczyzna to jeden z ciekawszych regionów etnograficznych, z ośrodkiem oryginalnej, świetnie zachowanej i pieczołowicie kultywowanej kultury ludowej Kurpiów. Obraz wsi kurpiowskiej jest wynikiem wielowiekowych działań człowieka. Na przestrzeni stuleci następowały przekształcenia krajobrazu, oparte na przystosowywaniu środowiska przyrodniczego do uprawy ziemi i stopniowym zakładaniu siedzib ludzkich, które dały obraz współczesny. Tradycyjna kultura ludowa kurpiowskiej grupy etnograficznej oraz wysoka wartość środowiska przyrodniczego były inspiracją do podjęcia badań z zakresu transformacji otwartego krajobrazu osadniczego regionu kurpiowskiego. Celem pracy było zbadanie procesów decydujących o przekształceniach krajobrazu naturalnego i kulturowego Kurpiowszczyzny. Zakres terytorialny pracy obejmuje obszar Kurpiowszczyzny położony między Omulwią i Szkwą, który w XV w. znalazł się w powiecie ostrołęckim i w nim pozostał. Zakres czasowy badania obejmuje okres od pierwszych wzmianek o zasiedlaniu obszaru do czasu przystąpienia Polski do Unii Europejskiej. Przyjęte zostały następujące metody badawcze: analizy bibliograficznej i piśmiennictwa dotyczącego tematu pracy, analizy historycznej obejmującej rozwój osadnictwa na badanym terenie, analizy kartograficznej porównawczej w zakresie osadnictwa i przekształcania krajobrazu, analizy statystycznej w zakresie infrastruktury społecznej i technicznej. W pracy posługiwano się także inwentaryzacją krajobrazową i urbanistyczno-ruralistyczną. Struktura cyklu, zawarta w siedmiu artykułach, obejmuje zagadnienia związane z kształtowaniem i rozwojem osadnictwa na obszarze Kurpiowszczyzny: 1) Kurpiowszczyzna w badaniach naukowych, 2) Kurpiowszczyzna w kulturze ludowej, 3) Kurpiowszczyzna – zarys kształtowania funkcji osadniczo- rolniczych i krajobrazu, 4) Kurpiowszczyzna – charakterystyka krajobrazu osadniczego, 5) Kurpiowszczyzna – dominujące zmiany w krajobrazie pod wpływem czynników społeczno-ekonomicznych w okresie 45-lecia powojennego, 6) Kurpiowszczyzna – dominujące zmiany w krajobrazie pod wpływem czynników społeczno-ekonomicznych w okresie transformacji ustrojowej. Cykl zamyka artykuł dotyczący współczesności: 7) Kurpiowszczyzna – 18 lat od wstąpienia Polski do Unii Europejskiej (publikacja w 2022).

Published: April 2021

O presente trabalho busca construir uma análise dos desafios e potencialidades na consolidação de coletivos de educadores, professores, na área de ciências da natureza nas licenciaturas em educação do campo da região sul do Brasil. Desta forma, buscamos organizar nossa exposição em três momentos distintos que perpassam ao histórico da constituição dos cursos de Educação do Campo a partir das políticas públicas educacionais como o PRONERA e PROCAMPO, contextualizando a construção e consolidação do coletivo de professores em ciências da natureza e dos cursos de educação do campo no Sul do Brasil. Na sequência do debate buscamos a compreensão teórica da constituição do ser docente na educação superior e consequentemente na licenciatura em educação do campo. A partir desta construção teórica buscamos apresentar as potencialidades e desafios da área de ciências da natureza nas licenciaturas em educação da UFPR, UFSC e UFRGS, debatendo o caminho para a consolidação de um coletivo de professores que trabalham as questões das ciências da natureza aliadas ao contexto camponês.

Authors: De Paula Adalberto Penha , Santiago Bufrem Leilah
Published: April 2021

Apresenta pesquisa sobre as relações entre a Educação do Campo, o Território e a escola da/na ilha em uma comunidade tradicional no litoral do Paraná. Objetiva compreender o significado que a educação e a escola do campo da/na ilha têm para as comunidades do litoral paranaense na relação com o território. O percurso teórico metodológico assume a concepção dialética do conhecimento e utiliza técnicas e procedimentos pertinentes ao enfoque metodológico de pesquisa do tipo etnográfica. Realiza observação participante, registro no caderno de campo, fotografias, questionários, entrevistas e estudo documental para produzir os dados e busca, na análise de conjuntura, os aportes necessários para o desvelamento da realidade. Constata como principais resultados que, as contribuições das produções acadêmicas sobre Educação do Campo se ampliaram; é preciso avançar com os processos realizados pela escola dentro das comunidades; embora práticas educativas já busquem articular cultura, trabalho enquanto modo de vida e o território, ainda há espaço para intensificar e aprofundar estas questões, consideradas essenciais na luta pela escola do campo da/na ilha. Conclui pela necessidade de que os sujeitos envolvidos na relação escola, comunidade e território busquem estratégias de aproximação e rompimento das fronteiras da alteridade, no sentido de avançar com um projeto educativo emancipador.

RESUMO

Esse artigo tem como foco a apresentação e análise dos dados de uma pesquisa a respeito da formação inicial de professores para trabalharem nas escolas do campo. O objetivo da referida pesquisa foi compreender como os cursos de pedagogia têm feito a formação inicial dos professores que irão trabalhar nas escolas do campo e nas escolas ribeirinhas. A pesquisa foi realizada nos sites das Universidades públicas brasileiras, federais e estaduais. O levantamento de dados considerou a oferta de disciplinas nos cursos de pedagogia das universidades federais e estaduais relacionadas à educação do campo: quantidade de disciplinas, carga horária, nome e ementas das disciplinas. Em 263 cursos de pedagogia analisados foram encontradas 112 disciplinas relacionas à educação do campo. No entanto, percebeu-se que, geralmente são ofertadas apenas 1 disciplina por curso e com uma carga horária irrelevante. Além disso, as temáticas encontradas privilegiam as questões mais gerais em detrimento das questões relacionadas às práticas pedagógicas.

Escola pública do campo no contexto das políticas educacionais
Authors: Hage Salomão Mufarrej , SILVA HELLEN DO SOCORRO DE , Freitas Maria Natalina Mendes
Published: April 2021

Este artigo tem sua origem nas atividades formativas, investigativas e de intervenção realizadas pelo Grupo de Estudo e Pesquisa em Educação do Campo na Amazônia-GEPERUAZ através do Programa Escola da Terra. Elas pautam uma análise do contexto das escolas públicas do campo, particularmente as escolas rurais multisseriadas e os desafios que se apresentam à execução do Programa Escola da Terra da Amazônia Paraense em meio aos retrocessos das políticas educacionais. A metodologia envolveu estudos bibliográficos, documentais e pesquisa de campo. Pautamos na discussão o contexto, princípios e desafios às práticas formativas de professoras/es no âmbito do Programa Escola da Terra executado no Brasil e na Amazônia Paraense; destacando o controle, a fragmentação e a hierarquização do tempo, do espaço e do conhecimento na escola imposto pelo modelo seriado de ensino, como base de sustentação de sua hegemonia; assim como alguns sinais que convergem para o enfrentamento e a desconstrução dessa hegemonia, assentados no processo de transgressão desse modelo hegemônico, que se materializa nas escolas do campo e quilombolas, sob a organização do ensino (multi)seriado.
Análise da qualidade dos cursos do Programa Universidade para Todos (PROUNI)

Published: April 2021

O artigo apresenta resultados de pesquisa que investigou a qualidade dos cursos que ofertaram bolsas do Programa Universidade para Todos, uma política implementada em 2005, com o objetivo de conceder bolsas de estudos de cursos de graduação em instituições de ensino superior privadas. Foi realizada análise quantitativa de dados dos cursos que ofertaram bolsas ProUni no município de São Paulo-SP em 2014, no que tange aos resultados de avaliação do Conceito Preliminar de Curso. Os resultados indicaram que os cursos selecionados que ofertaram o ProUni acompanharam a tendência de resultados de avaliação, não destoando dos resultados gerais dos cursos da educação superior brasileira. Entretanto, há uma parcela de cursos com ausência de conceito ou de reconhecimento, o que traz incertezas sobre a qualidade ofertada. Verificaram-se, também, diferenças em relação aos resultados conforme o grau acadêmico (bacharelados/tecnólogos), tipo de bolsa (integral/parcial) e área dos cursos.
