Etnocentrismo e liberalismo no neopragmatismo de Rorty
Authors: Silva Heraldo Aparecido
Published: October 2019

O propósito deste artigo é investigar a relação entre as noções de etnocentrismo e liberalismo na perspectiva do filósofo neopragmatista Richard Rorty. Nesse sentido, mostramos que essa tênue filosofia política, centrada nas referidas noções, enfatiza a conectividade entre as práticas conversacionais e as questões morais, políticas e sociais compartilhada por culturas diferentes. Na filosofia de Rorty, sua noção branda de etnocentrismo atua como um elemento articulador entre sua perspectiva anti-representacionista de conhecimento e sua versão de liberalismo político. A partir da crítica naturalista que inviabiliza as explicações transcendentais sobre a realidade, Rorty extrai as consequências historicistas necessárias para sua proposição de que há não limites, exceto os de caráter conversacional, para a apreensão e descrição do conhecimento. Nessa proposta etnocêntrica na qual não existe nada que seja transcendente em relação às práticas culturais, contingentes e históricas, tudo é considerado como dependente do provisório consenso intersubjetivo, em termos vocabulares e políticos de determinada comunidade e época.
Arte e virtude em Montaigne e Diderot
Authors: Alonso Bruno
Published: October 2019

Montaigne e Diderot foram filósofos, humanistas e defensores de um ceticismo crítico. Seus escritos se caracterizam por um estilo de escrita fluído, privado e cômico. Em Diderot vemos um filósofo dramaturgo, autor e crítico de peças teatrais. Em Montaigne um filósofo não acadêmico, um magistrado avesso ao perfeccionismo da filosofia escolástica, que instaurou um novo estilo de escrita. Há um traço em comum na forma como ambos compreendem a filosofia. Para Montaigne e Diderot, ética e estética são dois domínios da filosofia que possuem uma estreita relação. A obra de arte é um elemento essencial que possui o poder de despertar o espírito humano e conduzi-lo à vivência da verdadeira virtude.
Dionísio Pseudo Areopagita e o nada de Deus
Authors: Bezerra Cicero Cunha
Published: October 2019

Seguindo uma célebre afirmação heideggeriana, poderíamos dizer que a história da filosofia ocidental se constitui como uma onto-teo-logia. Essa assertiva, que em seu contexto crítico possui um sentido teórico-metodológico delimitado para os que buscam compreender a questão norteadora da filosofia grega e, posteriormente cristã, ou seja, a do fundamento do real ou do ser, não se sustenta quando aplicada à tradição apofática dionisiana. Marcado pelo diálogo com o neoplatonismo, o Corpus areopagyticum, por sua radical característica apofática, não somente coloca em suspensão uma certa linearidade histórico-filosófica herdeira do pensamento de Platão, mas instaura um modo de tratamento da linguagem humana para com o divino que permanece em vigor até os dias atuais. Esse artigo tem como finalidade pensar, à luz do diálogo com o pensamento neoplatônico, a noção de Deus como “nada de tudo o que é” e suas consequências para a teologia negativa dionisiana.
A ciência como um jogo em Popper
Authors: Dias Elizabeth de Assis
Published: October 2019

O objetivo do presente trabalho é analisar a concepção de ciência de Popper recorrendo metáfora com o jogo de xadrez que ele utiliza em sua obra A lógica da pesquisa cientifica. Consideramos que por meio desta metáfora é possível percebermos que a sua concepção de ciência não se reduz ao critério lógico de falseabilidade como muitos de seus comentadores deixam entrever, nem tampouco, em definir regras metodológicas para nortear a prática da ciência. Mas, o próprio filósofo ao estabelecer tal analogia deixa claro que a ciência tem em comum com o jogo de xadrez, a existência de regras. No nosso entender essas regras, assim como o critério de cientificidade, não são suficientes para definir a prática cientifica, pois esta envolve outros elementos como: valores, objetivos, comunidade cientifica e o contexto no qual as pesquisas são realizadas. Popper pressupõe esses elementos em sua metáfora, mas não os deixa explícitos. É somente em obras posteriores, como Conjecturas e refutações e Sociedade aberta e seus inimigos que eles são claramente definidos. Pretendemos assim, trazer a tona esses elementos envolvidos no jogo da ciência em Popper de modo a dar maior clareza a sua concepção.
John Dewey, reconstrução da filosofia e empirismo imediato
Authors: Gomes Thiago
Published: October 2019

Este artigo pretende abordar o conceito de filosofia de John Dewey, em sua especificidade em relação à tradição pragmatista. Para isso, partiremos da reconstrução da filosofia apresentada por este autor em Reconstruction in Philosophy, de 1920, obra na qual expõe completa e explicitamente o conceito e o que acredita ser o papel da filosofia. Em especial, caracterizaremos a concepção de filosofia de Dewey a partir das críticas que o pragmatista americano lançou contra certas maneiras de fazer filosofia, por ele denominadas filosofias modernas ou tradicionais. A partir dessa crítica, examinaremos o uso que Dewey faz de seu postulado do empirismo imediato, enquanto uma metodologia filosófica, para evitar os supostos equívocos das filosofias passadas e desenvolver uma filosofia que faz jus à experiência concreta.
A autonomia da vontade em Kant
Authors: Trapp Rogério
Published: October 2019

Ao longo desse texto intencionamos desenvolver a ideia segundo a qual há uma estreita conexão estrutural entre categorias como vontade, razão, autonomia, liberdade e causalidade no interior da filosofia prática de Kant. Assim, partindo da identificação de vontade e razão procuraremos demonstrar que esse paralelismo só é possível por meio da purificação da vontade e pela atribuição de uma função prática à razão. Entretanto, somente a purificação da vontade ainda não será suficiente para permitir a identificação entre vontade e razão. Com efeito, para identificá-las devemos demonstrar como passar da liberdade da vontade, da liberdade considerada negativamente, portanto, para a liberdade da razão prática, enquanto liberdade em sentido positivo.
Um ensaio de um “anti-orfeu”: perspectivismo cosmológico como contraponto à esferologia de Sloterdijk
Authors: Pitta Maurício Fernando
Published: October 2019

Este artigo problematiza o antropocentrismo na “esferologia” de Peter Sloterdijk, com sua narrativa da antropogênese como construção imunológica da “casa do ser”, na qual o humano, rompendo a “jaula” animal, constrói esferas, ilhas imunológicas de coexistência humana. O mito de Orfeu simboliza para Sloterdijk a imunologia: ao perder a amada, Orfeu reconstrói imunologicamente o complemento, neutralizando o espectro ausente como linguagem. Propomos um experimento filosófico, o “Anti-Orfeu”, no qual o perspectivismo cosmológico de Viveiros de Castro e Tânia Stolze Lima, pensado de um ponto de vista topológico, serviria de contraponto para pôr em perspectiva a imunologia, apontando para a variação da diferença entre dentro e fora e para a “antropofagia”, como outra distribuição topológica que permite outra relação com a alteridade que não a imunologia. Com isso, apontamos para uma “esferologia do ponto de vista do inimigo”, da alteridade, permitindo modular a esferologia, evidenciando-a como diagnóstico da “autoimunidade” de esferas imunológicas.
Design process of square column-shaped voice coil motor for magnetic levitation stage
Authors: Ahn Dahoon , Kim Hyunchang , Choi Kyungwho , Choi Young-Man , Lim Jae-Yong
Published: October 2019

Magnetic levitation is state-of-the-art technology to realize 6 degree of freedom motion stages. The major weakness of magnetic levitation technology is the small force of the actuators, since electromagnetic actuators usually have small force compared to other actuators. Moreover, they always have to be turned on in order to compensate for the weight of the stage. In this paper, voice coil motors, a kind of electromagnetic actuator, are designed for a magnetic levitation stage. Two different types of voice coil motors are mathematically modeled, analyzed and optimized to obtain high force. According to the optimized final designs, the voice coil motors are manufactured and their performances are evaluated. The optimal design results are compared with the finite element simulations and the test results of the manufactured products. Both types of voice coil motors show high force. The results are quantified and compared. Through the design process and the evaluation of the voice coil motors, a practical design guideline for a voice coil motor is suggested.

Published: October 2019

The extraction of impacted third molars is among the most common surgical procedures carried out in the field of Oral and Maxillofacial Surgery. For proper planning of surgical extraction, especially for impacted mandibular third molars the estimated level of surgical difficulty of the case is important. This study was conducted to evaluate the intraoperative risk factors contributing to surgical difficulty in extraction of impacted mandibular third molars and consequently the post-operative outcome. Here, we have undertaken a study in which the intraoperative variables were considered, to evaluate their contribution for surgical difficulty and postoperative complications in surgical removal of 100 impacted mandibular third molars. Three variables were found significant associated with total surgical time intervention, i.e., surgeon’s experience (p=0.006), Inter-incisal opening (p=0.032), and cheek flexibility (p=0.004). Total surgical time intervention for ‘right side’ was higher with 49.20 ± 17.94 minutes (p=0.691). Total surgical time intervention for ‘gagging reflex present’ was 50.21 ± 17.812 (p=0.674). Multiple linear regression shows that surgeon’s experience was the only predictor (p<0.001). The surgical difficulty of impacted mandibular third molar are likely to depend on the intraoperative factors like Surgeon’s time, surgeon’s experience, check flexibility, and inter incisal mouth opening.

Published: October 2019

The article deals with the specifics of the ceramic collection of 4 separate groups of burials (№1-4) of the Northern section of the Palace-Syrt burial ground of the IV–V centuries (hereinafter – the Northern Palace-Syrt), the excavations of which were carried out in 1982-1985. the Purpose of the study is to identify the features of this ceramic complex and to compare the data with the available results of the classification of ceramics of the barrow groups of the southern section of the burial ground (hereinafter – the southern Palace-Syrt), which was studied in 2009-2016.Separate burial mounds are essentially closed collective burial complexes connected by common social factors. Analysis of materials, such as certain groups of graves, and the comparative parsing of the entire series of mound groups located in the same area of the burial ground (planigraphy burials, funeral rites, especially the inventory, etc.), allows to determine in the burial traditions of the manifestations of the social structure of the population, and to identify common and particular in the ethnic composition of a large Union of tribes. The method of step analysis of the ceramic collection of burial mounds groups used in this work: burial – group of burials – group of burials of a separate certain area of the burial ground – group of burials of 2 sites of the burial ground, tested on the materials of the southern Palace-Syrt. It allows us to record both the General trends in the formation of the ceramic complex among the socially distinguished population, and to identify the principles of creating a clothing component of the funeral rite of the population. The authors give the characteristics of the sets of ceramics of each of the groups of burials of the Northern Palace-Syrt, on the basis of which a summary classification of the entire collection of ceramics is carried out. According to the authors ' conclusion, in the barrow groups №1-4 of the Northern Palace-Syrt there was no typological monotony of ceramic vessels, both in the sets of dishes of individual burial groups.

Improving the accuracy of ACIR data and increasing vaccination rates
Authors: Miles Thaïs A , Granger Linda V , Gately Colleen L
Published: October 2019

Immunisation at the earliest appropriate age and high levels of vaccine coverage at milestone ages are important in preventing the spread of vaccine-preventable diseases. At the Central Coast Public Health Unit, the authors sought to determine if follow-up of children said by the Australian Childhood Immunisation Register (ACIR) to be overdue for vaccination improved both of these factors.
In a quality improvement activity, monthly ACIR lists of overdue Central Coast children aged 9 to 10 months of age were examined. The study alternated three months of intervention with three months of no intervention. The intervention was designed to find evidence of vaccination, first from the last known provider, and then if this was unsuccessful, from the parent. If no information was available, a letter was sent to the parents. If the child was indeed vaccinated, the register was updated. If the child was missing any vaccinations, the parent(s) were encouraged to complete the schedule.
On reviewing routinely-published quarterly ACIR data at three-monthly intervals for 24 months after the intervention (or non-intervention), timeliness of vaccination improved in the intervention cohort. Central Coast fully vaccinated rates diverged from NSW rates during the study. In addition, the ACIR quarters that contained two out of three months of intervention rather than one out of three months of intervention had the highest rates of fully vaccinated children. The authors concluded that the intervention improved both timeliness of vaccination and the proportion of fully vaccinated children.
Free range eggs does not mean safe eggs: an outbreak of Salmonella Typhimurium linked to free range eggs
Authors: Sloan-Gardner Timothy S , Waters Natasha , Marmor Alexandra , Mude William
Published: October 2019

An outbreak of Salmonella enterica serovar Typhimurium with closely related Multiple Locus Variable-number Tandem Repeat Analysis (MLVA) patterns was detected by routine surveillance by the Australian Capital Territory Health Protection Service in May 2018. The outbreak consisted of three cases in 2018 (MLVA 03-10-10-09-496) and one in 2016 (MLVA 03-10-09-09-496), who reported eating home-cooked eggs from the same local producer. Environmental investigations found significant problems with egg cleaning, hand hygiene and documentation of food safety procedures on farm. Environmental samples collected from the farm were found to have the same MLVA pattern as the 2018 cases. Although poor farm practices most likely led to contamination of the eggs, this outbreak highlights the need for consumer education about safe handling of eggs in the home.

This type of research is correlational. The subjects of the study were 166 students of class X. Data thinking characters are collected using questionnaires of divergent / convergent thinking characters. Learning result data is obtained at the end of semester. Data analysis used is Pearson product moment correlation. The results show that there is a negative correlation between diverging thinking characters and learning outcomes.  This means that the higher the tendency of divergent thinking of the students, the lower the learning result, this is proved by the value of r-test (-0.121) <-r-tabel (-0,044). In addition, convergent thinking characters are positively correlated between convergent thinking characters and learning outcomes. This means that the higher the tendency of convergent students thinking, then the learning result will be high, this is proved by the value of r-test (0.048)> r-table (0.044). We conclude that: (1) the divergent thinking character of the students is negatively correlated with the learning outcomes; (2) the convergent thinking characters in the students are positively correlated with the learning outcomes.
