Fluid Mobilities? Experiencing and Responding to Othering in a Borderless West Africa
Authors: Darkwah Akosua K.
Published: August 2021

This paper seeks to interrogate the processes of othering that takes place in Ghana, acountry with a long history of migrants from the region now known as Nigeria. Thepaper draws on Spivak's (1985) concept of othering and explores both the ways inwhich Ghanaians othering of Nigerians is made manifest as well as the ways in whichNigerians respond to these processes of othering. Ultimately, I argue that until bothGhanaians and Nigerians recognize othering as a problem worthy of redress, the fullimport of the ECOWAS Protocol on Free Movement of Persons will be lost on thesetwo groups of West African citizens. For, while people can and do move across the 16borders of West Africa, they do not necessarily move freely. Migrants are oftenreminded of their status as the other even in a country where our founding fathersought to establish a strong sense of Pan African unity.

Published: August 2021

Background: Spondias mombin L. belongs to the family Anacardiaceae. Despite its wide ethnomedicinal applications in the management of diverse diseases, there is a paucity of documented reports on its standardization.Objectives: The present study evaluated microscopical characters and some physicochemical properties of different parts of the plant for its identification and standardization.Material and Methods: Epidermal tissue preparation of the leaf of Spondias mombin (SM) was obtained using physical method while thin sections (10-12 μm) of the stem bark and root were obtained using a rotary microtome. Physicochemical parameters were determined for the powdered samples of SM using standard methods.Results: Diagnostic characters from the epidermal tissue of the leaf revealed anomocytic, paracytic stomatal type, non-glandular trichome, smooth to slightly wavy anticlinal walls while sections of the stem bark and root were characterized with abundant sclereids and calcium oxalate crystals. The stomatal number and stomatal index of the abaxial epidermis were 23.70±0.86 and 24.62±0.78 %, respectively. Ethanol had the highest extractive value (17.84±0.50) % in the leaf whereas it was lowest in petroleum ether (1.92±0.08) %. The leaf had the lowest ash value (7.13±0.76) %.Conclusion: The microscopical characterization and some of the physicochemical parameters reported herein could be useful in the compilation of monograph for the correct identification of Spondias mombin, thus contributing to the knowledge of its collection and preservation.
PSO-Based Integral Sliding Mode Controller for Optimal Swing-Up and Stabilization of the Cart-Inverted Pendulum System
Authors: Shima T.J. , Bashir H.A.
Published: August 2021

An integral sliding mode controller (ISMC) which employs particle swarm optimization (PSO) algorithm to search for optimal values of the parameters of the integral sliding manifold as well as the gains of the controller is proposed in this work. We considered the swing-up and stabilization of the cart-inverted pendulum system which is assumed to be affected by uncertainties. First, we determined the swing-up and stabilization conditions of the control system by using the internal dynamics of the cart-inverted pendulum system and sliding mode dynamics. A PSO algorithm is then used to search for the optimal values of the ISMC design parameters that satisfy the stabilization condition with the aim of improving the transient performance of the control system. To mitigate the chattering phenomenon, a saturation function of the integral sliding variable was used in the discontinuous control law. Simulation results on swing-up and stabilization of the cart-inverted pendulum system revealed improvement in transient behaviour by reducing settling time (by 52.61%), overshoots (by 45.56%) and required track length for cart movement (by 68.34%).

Published: August 2021

Starch-g-acrylic acid hydrogel was prepared by free radical polymerization technique adopting potassium persulphate (KPS) as an initiator and N’N-methylenebisacrylamide (MBA) as a linking agent. The aim of the research is to inspect the potentials of starch-based hydrogel in remediating wastewater. Fourier Transform Infrared (FT-IR) spectroscopy was used to find the formation of hydrogel while Differential Scanning Calorimetry (DSC) and Scanning Electron Microscopy (SEM) were used for the characterization of the hydrogel. The FT-IR spectroscopy confirmed hydrogel formation. The DSC results showed that the generated hydrogel is thermally stable, and the SEM depicts a good porous site for dye adsorption. Batch adsorption for Rhodamine B (RDB) and Alkali blue (AB) dyes under the variation of contact time was 105 minutes for both dyes with percentage removal of 89.80 and 60.32%, adsorbent dose was 0.4 and 0.8 g with percentage removal of 86.42 and 57.95%, concentration was 50 and 30 ppm with percentage removal of 67.01 and 77.18% and pH was 8 for both dyes with percentage removal of 77.43 and 79.13% as the optimum. The results indicates that acrylic acid monomer was efficiently grafted on the starch, and the adsorption method correlated with Freundlich isotherm equation. It was concluded that the starch-based hydrogel is an appropriate adsorbent and can be explored for industrial wastewater treatment.

Published: August 2021

This study examines the effect of heat input on the weld bead profile, microstructure and mechanical properties of single V- joint welded carbon and stainless-steel plates. The as-received sample steel plates were sectioned into eight pieces; dimension 75 X 30 X 10 mm  thicknesses. Shielded metal arc welding (SMAW) of heat inputs 1250 and 2030 J/mm was used to produce full penetration bead on the plates. Although visual inspection indicated that some of the welds were macro defect free, austenitic stainless steel exhibited more weld distortions than the carbon steel and this was partially attributed to its lower carbon content and the width to depth aspect ratio of the weld profile aside the magnitude of the induced stress. For the carbon steel, as the heat input increased, the hardness value of both the heat affected zone and fusion zone increased. In contrast, for stainless steel, the hardness values were reasonably comparable within same weld region (HAZ or FZ) irrespective of heat input. Furthermore, the ultimate tensile strength of the stainless steel decreased as heat input increased while the ductility increased with an increase in heat input, in contrast to carbon steel, where both ductility and ultimate tensile strength generally decreased.

Published: August 2021

We investigate how governance and the Global Financial Crisis (GFC) affect cash management. Assessing 169,916 firm-years in 26 developing Asian countries, our empirical results show that firms in good (poor) governance countries tend to hold more cash before (after) the GFC. In particular, the outcome effect of governance on cash holdings in the pre-crisis and crisis periods shifts to a substitution effect for governance in the post-crisis period in developing Asia.

Published: August 2021

This study was conducted to evaluate the influence of tributyrin (TB) supplemented in diet on the growth, feed utilization and intestinal health of turbot (Scophthalmus maximus L.). Four experimental diets were formulated with TB at 0 mg/kg, 100 mg/kg, 200 mg/kg and 300 mg/kg levels respectively. A total of 2016 turbot (initial body weight: 31.22±0.05g) were randomly distributed into 12 tanks and fed the corresponding diets for 70d. Results showed that fish in 100 mg/kg group had significantly higher weight gain rate (WGR) and specific growth rate (SGR) than that in other groups (P<0.05). No significant differences were observed in survival rate (SR), feeding rate (FR), feed conversion ratio (FCR), condition factor (CF), hepatosomatic index (HSI), and viscerosomatic index (VSI) among all groups (P>0.05). There was no significant difference in intestinal superoxide dismutase (SOD) activities and intestinal malonaldehyde (MDA) contents among all treatments (P>0.05), while the highest SOD activity and the lowest MDA content were found in 100 mg/kg group. The height of intestinal fold in 100 mg/kg treatment was significantly higher than that in other groups (P<0.05). However, no significant difference existed in intestinal wall thickness among all groups (P>0.05). The present study suggested that 100 mg/kg TB inclusion level was recommended in the diets of turbot to promote the growth and improve the intestinal morphology structure and health in turbot.

Published: August 2021

This study was conducted to investigate the effects of the supplementation of fermented mealworm larvae meal with two different probiotic bacteria (Lactobacillus plantarum or Lactobacillus brevis) to diets of broilers reared normal or high stocking density on litter quality. Wood shavings, commonly used in broiler houses, are used as litter material. High stocking density significantly increased litter moisture content compared to that of broiler reared normal stocking density (P<0.0001). Dietary supplementing of fermented mealworm larvae meal with Lactobacillus plantarum or Lactobacillus brevis significantly decreased litter moisture content compared to that of control diet (P<0.0001). High stocking density significantly increased litter pH level compared to normal stocking density (P<0.0001). On the other hand, dietary treatments had no significant effect on litter pH. High stocking density significantly increased ammonia gas emissions in the 5th day (P<0.05) and 7th day (P<0.0001) compared to normal stocking density. Furthermore, feeding on diets supplemented with fermented mealworm larvae meal with Lactobacillus plantarum or Lactobacillus brevis numerically decreased ammonia gas emissions in the 5th and 7th days although their effects on ammonia gas emissions are not significant. It was concluded based on present findings that fermented mealworm larvae meal with probiotics can be used as a natural feed additive to prevent the problems resulted from wet litter and high indoor ammonia levels in broiler houses.

Canarium Odontophyllum or known as Kembayau and/or Dabai (Dacryodes rostrata f. cuspidate) is an underutilized exotic (indigenous) fruit that can be found in Borneo region particularly Sabah, Sarawak, Brunei and Kalimantan tropical forest. Kembayau is less popular compared to Dabai fruit due to the taste and thickness of flesh. It is rich in minerals, proteins and carbohydrates with milky taste. This study was done to determine the suitability of Kembayau fruit as a sauce. Three formulations, F3, F5 and F8 out of nine were chosen after going through BIB ranking test and F8 then chosen through hedonic test for proximate analysis, microbial storage study and quality sensory. F8 contains 45% Kembayau fruit puree, 30% sucrose, 18% water, 1.53% modified corn starch, 0.1% xanthan gum, 4% margarine, 0.9% salt, 0.4% citric acid and 0.07% sodium benzoate. As result, Kembayau fruit sauce contains 60.43±0.40 moisture, 0.50±0.10 ash, 0.75±0.03 fat, 1.40±0.07 protein, and 0.92±0.02 crude fibre and 35.50±0.04 carbohydrates. Physicochemical shown sample had pH at 3.15±0.10, 34.00±0.01 °Brix, viscosity at 24.42±0.10 cP and L*a*b* was at 39.75±0.18, 6.12±0.07, and 12.42±0.08 respectively.

Published: August 2021

Corrosion is a process of deterioration of metal surfaces where the metals were degraded into another compound. Soil is one of the medium known to have constituted to corrosion of metals. The soil creates an environment for the movement of electrons. The level of corrosion in soil can vary from major material loss or to minor effects. The buried pipelines are exposed to the soil that may experience corrosion attack. The study of the soil as a corrosive environment is important to mitigate the problem which may be serious to the environment and economy. There are few factors that contribute to the corrosion processes. This review focuses only to sulfate and sulfate reducing bacteria in soil. Hence, this review investigates the relationship of sulfate and sulfate-reducing bacteria in soil.
Assessing Carbon Pools in Dipterocarp Forests of Peninsular Malaysia

Published: August 2021

Modification and loss of forests due to natural and anthropogenic disturbances contribute an estimated 20% of annual greenhouse gas (GHG) emissions worldwide. Accounting GHG emissions associated with forestry, specifically, and land use generally is crucial in recent days because forests play major roles in balancing terrestrial carbon and contribute to the mitigation of global warming and climate change. Consequent to the awareness of climate change, reducing emission from deforestation and forest degradation, and conservation (REDD+) programmed was introduced at the international level to promote forest conservation and enhance forest governances. Intergovernmental Panel on Climate Change (IPCC) came out with protocols on how to account the carbonstored and released from the forests. Principally there are five primary carbon pools in a forest, which are above-ground biomass, below-ground biomass, deadwood, litter, and soils that accumulate and in some conditions release carbon. However, about 98% of carbon stored in a forest comprises trees components (aboveground and belowground living biomass, deadwood and litters) and the remaining is stored in soils. Many factors interact to affect the flux dynamics of these carbon pools, including the type of forest ecosystem, the age of the forest, and if harvested, the length of stand rotation cycles and the forestry practices used. Logging these forests, in a sense, represents an opportunity cost, as the time necessary for a harvested forest to regain its carbon sink capacity can take many decades, and if left undisturbed, would have gone on to expand its carbon pool or at least remain in constant over time. In this study, the lowland dipterocarp forest, where logging often takes place, is profiled in terms of biomass carbon. Pahang, which has the largest forest cover and biggest timber production in Peninsular Malaysia, was selected as the study area. The dipterocarp forests comprise both protection and production functions were categorized into strata based on year elapsed after logging (i.e. logged 1-10, 11-20, 21-30, and > 30 years). Measurements have been conducted on the ground and all the carbon pools in these strata were assessed. The study found significant differences between each stratum in terms of carbon and the results are presented in this paper. The effects of harvesting practices on carbon pools are also discussed.

As public concern towards the long term effect of synthetic materials used in cosmetic formulations, such as the synthetic colorant, therefore natural ingredients are getting more preferred. In this research, evaluation of potential natural colorant extracted from H.polyrhizus, C.ternatae and P.amaryllfolius were investigated in terms of pigments stability against heat exposure. Pigments from each sample were exposed at different temperatures (30°C, 37°C, 40°C, 50°C, 60°C, 70°C, 80°C). Color intensities were measured at 517 nm and compared with control over a week to observe color changes and absorbance readings. Heat treatments were done to investigate the suitability of pigments to be incorporated as colorant in cosmetics products (lipstick) because the production of lipstick required high temperature to melt the ingredients. Pigments from H.polyrhizus showed to be most stable after heat treatment in comparison to C.ternatae and P.amaryllfolius. A premarket survey was done to investigate the customer acceptance on natural vs. synthetic products. Extracts from H. Polyrhizus (red), C.ternatae (blue) and P.amaryllfolius (green) were used to produce natural lipstick where matching synthetic colorant were used to produce another set of lipstick. An online survey was sent to 50 respondents all over the world from the age of 16-52 years old to investigate acceptance on the natural vs. synthetic product. Ranking test (Likert Scale) and hedonistic test were used to compare the best accepted product, color and pH. The consumer acceptance was investigated using the Ranking Test (Likert Scale) and Hedonic Scale test. At the end of the investigation, natural red lipstick was being chosen as the best preferred lipstick at 80% regarding its color and pH. All statistical analysis was done by SPSS and p value <0.05 was considered as significant. The finding suggested that natural colorant (red) was more preferred in comparison to synthetic colorant in cosmetic product based on its color and pH preferences. Thus, focus should be directed towards use of H.polyrhizus in cosmetic products due to higher stability and customer preferences.

Published: August 2021

Purpose

To compare the duration of exercise and magnitude of external load per type of exercise (warm-up, small-sided games, position games – movements with/without ball but without the dynamics of a real game, simulations of real games – 11 vs. 11, fitness exercises, large-sided games, technical drills) during different training days in professional soccer players and test the relationships between duration of exercise and the external load.

Methods

Overall, 22 professional soccer players (25.1 ± 2.9 years, 181.9 ± 6.3 cm, 73.1 ± 6.3 kg) were daily monitored by a microelectromechanical system. The training duration (minutes) and the external load measures of total distance covered and high-speed running distance were collected for each type of exercise.

Results

Repeated measures ANOVA revealed significant differences in training duration, total distance covered, and high-speed running distance between the exercises (p < 0.001). A greater total distance was covered in simulations of real games (2321 m/session), as well as high-speed running (84.6 m/session). The total distance covered in simulations of real games was greater by 77% than in small-sided games, while that in high-speed running in simulations of real games was greater by 153% than in large-sided games.

Conclusions

The study revealed that simulations of real games and position games were the exercises that occupied the most time in the sessions and that the simulations of real games were the greatest contributor to distance covered and distance covered at high-speed running.

Unlike in the previous decades, strength training is gaining more scientific attention owing to its numerous benefits on human health. It has major benefits on metabolic processes, cardiovascular system, musculoskeletal system, age-related processes, and mental health. In comparison with aerobic low-intensity exercises, chest press-based strength training cardiovascular adaptations have been ignored for many years. Yet, if properly prescribed and conducted, strength training has shown to be safe and effective in people with cardiovascular disease. This narrative review aims at summarizing the available evidence

about the role of chest press-based strength training on the cardiovascular system.

Authors: Rocha Fernando , Conceição Ana , Mata Carlos , Narciso Janine , M. Costa Aldo , Branco Marco , Louro Hugo
Published: August 2021

Purpose.

Exercise performed improperly, in disagreement with age and development, may trigger negative bioactive effects. Adolescent taekwondo athletes, being able to practise on tatami or without tatami and barefoot, may be submitted to musculoskeletal structure disorders. The purpose of this study was to describe the frequency and amplitude of the reactive forces during taekwondo practice with and without tatami.

Methods.

Overall, 27 adolescent taekwondo athletes aged 10–15 years were submitted to a standard 90-minute training session with and without tatami. During each session, the frequency of ground contacts and the vertical ground reaction forces were measured. Femur and wrist bone age and the respective stages of the epiphyseal plate were computed from radiograph images. A total of 6346.6 ± 425.5 ground contacts (an average of 106 contacts per minute) were registered during the training session. The Wilcoxon test was applied to analyse the relationship between taekwondo and epiphyseal plate stage (p ≤ 0.005).

Results.

Student’s t-test revealed a significant difference between ground reaction forces with and without tatami; tasks performed without tatami featured smaller magnitudes for comparisons of absolute and normalized values (t = –3.359; p < 0.002 and t = –3.652; p < 0.001, respectively). The time of practice showed no early closure of the femur epiphyseal plates caused by the practice of taekwondo.

Conclusions.

Practising taekwondo seems to have a bio-positive effect on the maturation of adolescent athletes, regardless of the use of tatami.

Sublime borders: modernism, music and the negative
Authors: Bertola Mauro Fosco
Published: August 2021

“After the fall of formal beauty, the sublime was the only aesthetic idea left to modernism” (Adorno 1997: 197). Positioning at its core the category of the sublime, the modernist aesthetic famously engenders a problematic relationship between music – characterised as an autonomous, self‑relating agent of nonrepresentational negativity pursuing on its own terms a powerful critique of the Western metaphysic of presence – and its embeddedness in cultural contexts. At its most radical, like in Lyotard’s aesthetic, music’s ‘immaterial matter’ becomes a traumatic, ‘in‑human’ Otherness, a sublime, otherworldly sound-event, “which is not addressed […and] does not address” (Lyotard 1991a: 142). The musicologist Susan McClary recently highlighted how in the last few decades a new generation of composers has arisen, which by still drawing on the modernist tradition nonetheless engages more directly with signification and the cultural inscription of music. On this basis McClary calls for rehabilitating the allegedly feminine category of the beautiful, thus relocating music’s essence within the anthropological boundaries of pleasure and opening it for cultural diversity and contextuality. Yet, is the beautiful the more apt category for aesthetically framing this artistic development? As Catherine Belsey has pointed out, the specific twist at the core of Žižek’s philosophy consists in its conflating Lacan’s psychoanalytical theory of sublimation with Kant’s concept of the sublime (Belsey 2005: 141). Žižek’s sublime object thus intermingles not only pleasure and pain but also the absolute negativity of the Lacanian Real and the positive features of its cultural inscription. In my paper I explore the potential this theoretical frame offers for reading these recent artistic developments neither in terms of a domesticated modernism nor as a return to the aesthetic category of beauty as a culturally embedded fit between form and content. Instead, I will propose that we read them as the exploration of a specific, twisted space at the crossroad of the ‘meaningful’ positivity of culture and that ‘sublime’ negativity that the modernist aesthetic sees as the nonrepresentational essence of music.
Considerações Acerca de uma Estética Negativa em Theodor W. Adorno
Authors: Caires Correia Fábio , Perius Oneide
Published: August 2021

A obra de arte é um fato social. É um produto social de indivíduos sociais, e sua lógica é construída a partir dessa visão. Mas deve principalmente ser autônoma. É na arte que a radicalidade da dialética encontra sua maior expressão. Pois, sendo expressão dialética e, ainda, negativa, ela é ao mesmo tempo social e antissocial. É a partir desta tensão entre autonomia e determinação que é desenvolvida a Teoria Estética (Ästhetische Theorie). O objetivo deste texto é, neste sentido, apresentar a radicalidade da teoria estética negativa adorniana como uma tentativa de trazer à luz não só outro esquecido pela razão moderna, mas, e de forma mais específica, pensar a liberdade em meio a uma sociedade de não-liberdade. A estética negativa, enquanto sensibilidade e movimento para o não-idêntico é, neste sentido, moção e fundamento de apoio à ética, enquanto propensão a uma possível vida menos errada.

Para Gilles Deleuze, o pensamento é indissociável de uma experimentação ou experiência que o force a pensar; de um aprendizado através da constituição de problemas; e de um ato de criação que atualize as Ideias em obras de arte ou conceitos. A filosofia e a arte são disciplinas de pensamento distintas, mas que tem em comum a remissão a modos de sentir. Queremos problematizar neste artigo o quanto a sensibilidade, entendida no sentido de uma matriz do pensamento – tal como propõe Deleuze – remete a uma apropriação de certos aspectos da terceira Crítica de Immanuel Kant. Em primeiro, uma apropriação do conceito de sublime enquanto violência que força aos limites das faculdades; em segundo, uma crítica do senso comum e da concórdia das faculdades; em terceiro, o caráter estético das ideias, tal como aparece no momento do gênio kantiano, pensado por Deleuze como ato de criação. Sob esses três eixos, poderemos discutir a fecundidade de um intercâmbio entre filosofia e arte no que diz respeito a questões de estilo e método, ante os problemas vitais de nossa existência, problemas que ambas enfrentam. A estética, aparece-nos nesse sentido, à primeira vista como uma espécie de “organon”, ou instrumento do pensamento, mas, para além disso, a experiência estética (como instância da experiência comum entre a arte e a filosofia) seria considerada como heterogênese do pensamento, que já não diz respeito a uma “representação” (moral), mas a diferenças no sensível que escapam a fixação em percepções ordinárias.

O homem de gosto e o egoísta lógico surgiu, a princípio, como tese de Mestrado em Filosofia de Arthur Grupillo, pela UFMG. A dissertação foi indicada pela ANPOF, no biênio 2006-2007, ao prêmio de melhor tese e dissertação. Atualmente professor adjunto da Universidade Federal de Sergipe, após doutoramento com estágios de pesquisa nas Universidades de Kassel e Frankfurt am Main, e focado em temas da estética e do pensamento pós-metafísico, o pesquisador lança uma versão revisada e aperfeiçoada daquele texto.
Objetos de emoções: objetos de amor, tecidos afetivos, peles...
Authors: Marim Caroline
Published: August 2021

Na “Era da Estética”, um objeto ganhava o estatuto de “obra de arte” a partir de um tipo particular de experiência vivida pelo espectador: a experiência estética. Depois do fim da arte, Arthur Danto aponta que o que faz um objeto ser considerado arte, não é visual, mas conceitual. A diferença não pode ser sensível porque não pode ser estética. Entretanto, se considerarmos o que Suely Rolnik aponta, sobre a obra Estruturação do Self, de Lygia Clark, como uma reinvenção da experiência estética que havia desaparecido do universo da Arte, de que modo podemos reavivar a experiência estética dentro do contexto de uma “Arte pós-histórica”, na qual o artista também é filósofo e as obras, acontecimentos? Para Brian Massumi (2011), o engajamento relacional da obra confere-lhe um valor político tão necessário e imediato quanto a dimensão estética. Sara Ahmed (2010) defende que a emoção é aquilo que sustenta ou preserva a conexão entre ideias, valores e objetos. As emoções nasceriam em meio a uma experiência na qual o objeto se descoisifica e na qual as emoções são as forças de encontro. A experiência estética é uma filosofia ativista: um tornar-se. Tornar-se feliz. Aqui – claro - a felicidade é entendida mais como prazer obtido, por vezes, até com o contato com a dor e com os próprios vazios, como propôs Lygia Clark em sua Estruturação do Self.
Alegoria da caverna, o desejo e a verdade
Authors: Soares da Silva Felipe Gustavo , Borges de Araujo Junior Anastacio
Published: August 2021

The present work is a discussion on the nature of the philosophical desire, as proposed by Plato in the Republic - more specifically in the myth of the cave. Through a commentary on the passage of myth, we discuss about how one can infer from this passage a metaphysics of desire that guides to the synthesis of the philosophical desire.
A filosofia vai À escola: o que é isto?
Authors: Santos Olegario Hilson , Cornelio Matos Junot
Published: August 2021

Pensar o ensino da disciplina de Filosofia é uma tarefa bastante atual. Talvez porque as outras disciplinas como a matemática, o português, a geografia, por exemplo, já tenham historicamente consolidado seu conteúdo curricular na educação básica; mas, talvez não. Porém, pensar o ensino de qualquer disciplina requer pensar a escola. Qual escola está sendo tratada aqui? Certamente não é a escola ideal, muito menos uma específica como estrutura física delimitada. O que tratamos aqui é o modelo de escola, como concebemos este lugar comum a todas as disciplinas que varia de acordo com a proposta político-pedagógica das instituições. As escolas parecem compor uma variedade de opções na formação das pessoas. Umas voltadas para a formação profissional, outras direcionadas para levar os jovens às universidades. Mas, a quê serve a escola? Assim, buscaremos perceber a conjectura onde está sendo introduzido o ensino de filosofia como disciplina da escola, aonde os professores/pesquisadores ainda buscam desde 2008, justificar sua presença, construindo seu espaço neste nível do ensino para então, poder tomar posição quanto ao ensino da disciplina de filosofia propriamente dita que em nosso entender não deve se prender a utilidade da filosofia, nem ser meramente fixa a conteúdos da história da filosofia.
USO DO TEXTO FILOSÓFICO EM SALA DE AULA: PARA ALÉM DA FILOSOFIA ANALÍTICA DA LINGUAGEM PELA INTERPRETAÇÃO DOS ESTUDANTES

Published: August 2021

Uma das preocupações essenciais no ensino de Filosofia é a experiência daleitura em sala de aula, especialmente dos textos de Filosofia. A leitura éelemento fundante da aprendizagem uma vez que conduz, com a escrita e aoralidade, ao processo de letramento, ou seja, fazer uso social das experiênciasem sala de aula. Na leitura do texto filosófico, o estudante é convidado à umaexperiência do texto filosófico. Nesse sentido, o presente artigo discute umaexperiência em sala de aula, de leitura e interpretação de fragmento do texto deEmmanuel Levinas, “Totalidade e Infinito”, em uma turma do Ensino Médio,2o ano, sem a preocupação analítica do texto, com livre interpretação dosestudantes, considerando o sentido objetivo da temática. O processometodológico se desenvolve pela sensibilização, problematização, leitura,pesquisa de conceitos e interpretação. Muitas vezes fundamentos em discursosanacrônicos, a falta de problematização e os conteúdos de base histórica nãopermite aos discentes desenvolverem a sua própria capacidade de compreensãodo texto, a partir de referenciais mediados pelo professor, mas não comentadospelos mesmos.
O valor da verdade segundo as Confissões de Agostinho de Hipona
Authors: Evangelista de Oliveira Jandui , Nunes Costa Marcos Roberto
Published: August 2021

Mais do que um conceito, a verdade é para Agostinho aquilo que, por assim dizer, fundamenta sua própria subjetividade. Por meio de sua descoberta vemos uma grande transformação na vida do Bispo de Hipona: desde sua conversão ao cristianismo, bem como, o começo da sua atividade filosófica. Em vista disso, o presente trabalho procura mostrar e, ao mesmo tempo, analisar a busca de Agostinho por seu eu mais profundo que, em última medida, culminará com seu encontro com a verdade. Onde, a verdade vai se constituir como aquilo que ele encontrou depois de percorrer os caminhos mais diversos em sua vida pregressa. Para tanto, partimos das Confissões, obra na qual ele relata todo esse percurso, o que justifica nossa compreensão de que aqui essa questão é apresentada de forma mais consistente e amadurecida. Por outro lado, procuramos também, fazer uma ponte, vez ou outra, com as contribuições de alguns comentadores sobre a temática em questão.
TRANSTEÍSMO: UMA ABORDAGEM ENTRE KIERKEGAARD E HEIDEGGER
Authors: Ericksen Lauro
Published: August 2021

O trabalho almeja analisar a influência de Kierkegaard em Heidegger, especificamente na questão da subjetividade. Por transteísmo, deve ser compreendida a abordagem de Tillich, de que as práticas sociais são secularizações de rituais religiosos, de modo que, sem pender para o teísmo ou para o ateísmo, a prática social pode se desenvolver independentemente de ser atrelada a uma dessas perspectivas, podendo cada um encontrar a Deus subjetivamente. Tem como objetivo mais amplo analisar como, transteisticamente, Heidegger assimila a verdade como subjetividade. De maneira específica, visa apontar o caráter ontológico da descrição da subjetividade em Kierkegaard, indicar um paralelo teológico na obra heideggeriana a respeito desse tema, e, ressaltar o elemento transteísta que permeia essa remodelagem heideggeriana. Como resultado, aponta que Heidegger transforma a posição teológica de Kierkegaard em um apontamento filosoficamente relevante, algo deveras importante na filosofia continental contemporânea. Conclui que a abordagem transteística dada por Heidegger traduz em termos laicos a proposta da subjetividade como verdade de Kierkegaard, tomando o tempo como contexto interpretativo para o Dasein, na primeira fase de seu pensamento (Ser e Tempo).
As mulheres na filosofia: relatos de uma pesquisa
Authors: Marinho Nogueira Maria Simone
Published: August 2021

Minha participação nesta mesa-redonda é fruto de uma provocação. Trata-se de tentar responder a pergunta feita por uma ou outra pessoa da Filosofia: “por que não há mulheres filósofas?”. Na Contemporaneidade, por exemplo, muitas mulheres se destacaram no cenário da filosofia, nomes como o de Hannah Arendt, Simone Weil, Edith Stein e Maria Zambrano são apenas algumas ilustrações de uma escrita que estamos chamando de feminina e que pode e deve ser resgatada. Na Idade Média, meu recorte nesta mesa-redonda, apesar de um maior domínio da figura masculina, também houve um pensamento feminino mais ligado, entretanto, à mística. Encontramos, assim, uma gama de escritoras femininas que, de alguma forma, nos permite pensar numa reescritura da história, sejam seus textos lidos como transgressores, destituídos de sentido ou, simplesmente, escritos mais com o corpo do que com a razão. É o pensamento dessas mulheres que queremos trazer à tona, oferecendo uma possível reflexão sobre saber e poder na Filosofia Medieval.
Uma Teoria da Consciência
Authors: Dutra Gabriel , De Athayde Prata Tarik , Rosenthal David
Published: August 2021

Uma divisão cuidadosa de tarefas muitas vezes facilita nossa compreensão das coisas. Isso não é menos verdadeiro no estudo da mente que em outras áreas de investigação. Por exemplo, por causa da diferença radical entre os aspectos intencionais e sensoriais dos estados mentais é amplamente aceito que nós faremos progresso ao estudar cada tipo de propriedade independentemente da outra. Claro que muitos fenômenos mentais, como percepções e emoções, possuem os dois tipos de propriedade; no entanto, há outros estados mentais que exibem apenas uma das duas. E a diferença entre um caráter intencional e um sensorial é tão pronunciada que o estudo de cada um deles levanta problemas distintos. Realizar investigações independentes nos permite ignorar os problemas irrelevantes.
A AULA NA EDUCAÇÃO SUPERIOR: DESAFIOS E PERSPECTIVAS NA ATUALIDADE
Authors: Viana Cleide Maria Quevedo Quixadá , Da Silva Edileuza Fernandes
Published: August 2021

As transformações provocadas pelo advento da Revolução da Robótica e da Informática e o reflexo da crise estrutural do capital impactaram em mudanças na nossa sociedade, mudanças estas, impostas pelos organismos internacionais ao governo brasileiro e por este, à nossa sociedade, dentre elas, as reformas relacionadas à Educação. O artigo analisa os desafios atuais enfrentados pelo professor, suas implicações na concepção, organização e desenvolvimento da aula na educação superior. A discussão, baseada em estudo bibliográfico, concebe a aula como um projeto colaborativo que, conforme Veiga (2008), pressupõe uma ação colaborativa entre pares e alunos que problematizam, discutem, analisam, decidem, executam e avaliam as atividades propostas coletivamente, sendo parte da responsabilidade e do compromisso ético do professor e de alunos, com a instituição de ensino, a educação e a sociedade.

Authors: Bianchi Caio Giusti , Godoy Rosana Pêgas
Published: August 2021

A monitoria pedagógica tem sido reciclada ao ultrapassarem a dimensão formal e imprimem sentido para o monitor (formação docente), professor (suporte e atualização) e estudante (suporte na aprendizagem). Então, o objetivo da pesquisa é identificar a relevância da monitoria pedagógica para a inovação de técnicas pedagógicas e formação docente na educação de nível superior. Para tanto, foram realizadas sete entrevistas com monitores pedagógicos, analisadas por meio da análise de conteúdo temática. Foram identificados três pilares de influência na monitoria pedagógica: motivação dos monitores em participar do processo; relevância do suporte institucional e do relacionamento interpessoal entre professores, monitores e estudantes.
