Nós x eles: ensaio sobre estigma na atualidade
Authors: Machado Paula Dioné Casais e Silva , Rabinovich Elaine Pedreira 
Published: October 2024

A atual discussão sobre a problemática do bastardo acaba por igualar todas as formas de estigmatização, porém, apesar de os indivíduos estigmatizados apresentarem grande heterogeneidade entre si, todos trazem em comum certas características, sobre as quais o ensaio discorre. Tendo como base a questão do estigma enquanto desvio da norma, aborda-se a perspectiva da “diferença”, que supostamente afasta os indivíduos estigmatizados dos demais (igualando todas as formas de estigmatização), e a perspectiva da “semelhança”, que permite que as minorias se aproximem, na busca comum por organizar vozes a fim de debelar a exclusão e conquistar um objetivo compartilhado: o pertencimento. Argumenta-se que o estigma, além de meio concreto de materialização da dominação por meio da segregação, é também máquina de identidade coletiva potente, pois é determinante no processo de elaborar as características destacadas. Reflete-se ainda sobre a necessidade de combate à estigmatização, discutindo-se possíveis estratégias de enfrentamento.

A proposta deste artigo consiste em compartilhar dados de um estudo desenvolvido com mulheres trabalhadoras sexuais sobre suas práticas e dinâmicas de socialização, formação, cuidado e educação dos seus filhos e filhas. O referencial teórico se circunscreve ao campo de estudos em educação e dialoga com referenciais teóricos da Sociologia, da Antropologia e da Psicologia. A pesquisa realizou-se por meio de visitas a locais onde as trabalhadoras sexuais exercem seu trabalho, unidades familiares e rua. As técnicas foram entrevistas, histórias de vida, histórias de família, contatos com as famílias observação e construção etnográfica. Os resultados apontaram que as famílias das trabalhadoras sexuais, as famílias de Putas, não se diferenciam em termos de organização dos outros modelos de famílias. Entretanto, a convivência com mães trabalhadoras sexuais constrói sujeitos com olhares diversificados e abertos às questões apresentadas pelo Movimento de Trabalhadoras Sexuais. Por outro lado, o processo de organização e colaboração das trabalhadoras sexuais preconiza uma forma de cuidado pautada na solidariedade, rede que se apoia e organização coletiva no processo de socialização e educação dos filhos e filhas: a roda colaborativa é uma expressão de como as redes de afeto contribuem no “corre” das mães que também são Putas.

Published: October 2024

Fused deposition modeling (FDM) 3D printing is one of the additive manufacturing processes that can make components with complex shapes, require no tools, are cheap, safe, and have minimal waste. Despite all the advantages of the FDM process, the inability of this technique to create holes on a micro scale can be a problem and limits its application. In this research, a combination of FDM and machining processes was carried out, where micro holes in FDM printed components were created using a punching process. The punching process is carried out by varying pressure and speed. Furthermore, the diameter of the hole and the quality of the sheared edge of the hole resulting from the punching process were evaluated through observation using an optical microscope. The results show that the holes resulting from the punching process have a better shape and diameter than the FDM process. Then, the analysis of the sheared edge from punching shows that pressure and speed significantly affect the surface quality of the resulting sheared edge, where the quality increases with increasing pressure and speed. In the end, the punching process was proven to create micro-scale holes in FDM-printed polymer, especially at minimum thickness.

Published: October 2024

В последние десятилетия в гуманитарных науках активно обсуждаются проблемы гендерности – совокупности социально-культурных норм поведения, в том числе речевого поведения, которое общество предписывает людям в зависимости от пола. Гендерные различия проявляются в разных сферах и ситуациях, они оказываются актуальными и в такой области, как преподавание иностранных языков. Статья посвящена описанию и анализу проявления гендерных различий в процессе освоения китайскими студентами русской интонации. Приводятся примеры интонационных ошибок, допускаемых студентами-юношами и студентками-девушками; указываются причины ошибок биологического (природного) и социального характера; ставится вопрос об учете гендерных различий при обучении интонации и в преподавании русского языка китайским студентам в целом.
In recent decades, the humanities have been actively discussing the problems of gender – a set of socio-cultural norms of behavior, including speech behavior, which society prescribes to people depending on their sex. Gender differences manifest themselves in different spheres and situations, they turn out to be relevant in such a field as foreign language teaching. This article talks about the manifestation of gender differences in the process of mastering Russian intonation by Chinese students; gives examples of intonation errors made by male and female students; points out the reasons for errors of biological (natural) and social nature; raises the question of taking gender differences into account when teaching intonation and teaching Russian to Chinese students in general.

Authors: Скворцова Н.Н. , Чао Ч. 
Published: October 2024

В статье представлена типология автосемантичных фрагментов как особых единиц художественного (реже – художественно-публицистического) текста. Автосемантичные фрагменты описываются с учетом взаимосвязи их формальных и содержательно-смысловых аспектов; рассматриваются также наименее изученные виды и разновидности автосемантичных фрагментов, выделенные исходя из функционирования в субъектных формах речи и степени автономности содержания («отчуждения» от сюжетного повествования).
The article presents the typology of autosemantic fragments as special units of an artistic (less often – artistic and journalistic) text; describes the types and varieties of autosemantic fragments taking into account the interrelation of their formal and content-semantic parameters; considers the least studied types and varieties of autosemantic fragments that are identified based on their functioning in the subject forms of speech and the degree of the content autonomy («alienation» from the narrative plot).
