Between scientia sexualis and ars erotica: Power, resistance and subjectification in psychoanalysis

Indexación: Scopus; ScieloLa recepción del psicoanálisis freudiano por parte de Michel Foucault ha sido caracterizada como ambivalente, con una marcada crítica hacia el pensamiento de Freud y la práctica psicoanalítica, en el contexto de la reflexión sobre los mecanismos de poder emprendida por el filósofo en los años 70. Se propone discutir dicha caracterización a partir de la revisión del concepto de souci de soi y la noción de subjetivación, ofreciendo una opción para sostener la capacidad de resistencia del psicoanálisis en tanto forma contemporánea de ars erotica, calificación que le posibilitaría desmarcarse de una participación privilegiada en el dispositivo de sexualidad y la subsecuente adscripción en el campo de las tecnologías gubernamentales que de ello se deriva, permitiendo de tal forma un desplazamiento estratégico que pueda mostrar la afinidad del psicoanálisis con una ética del cuidado de sí y las implicaciones de su práctica en la invención de nuevas formas de subjetividad y ejercicio de la libertad.http://ref.scielo.org/v4pn5

An explanatory model of sexual satisfaction in adults with a same-sex partner: An analysis based on gender differences

This study aimed to develop an explanatory model of sexual satisfaction in same-sex attracted individuals with a partner, based on personal and interpersonal variables. The participants were 410 men (mean age = 29.24, SD = 9.84) and 410 women (mean age = 29, SD = 8.57) who maintained a relationship with another person of the same sex. Internalized homophobia was considered as a personal variable, and as interpersonal variables, the dimensions of attachment (anxiety and avoidance), sexual functioning, dyadic adjustment, relationship satisfaction, the components of the Interpersonal Exchange Model of Sexual Satisfaction, the number of sexual costs and the number of sexual rewards were considered. The degree to which sexual satisfaction was related to these variables was examined separately, for both men and women, through multiple linear regression models within the framework of structural equation models. The results indicated that sexual satisfaction is associated in a negative sense with internalized homophobia, the number of sexual costs, anxiety, and avoidance, and in a positive sense with the remaining variables. Relational variables were more relevant in the explanation of sexual satisfaction. The clinical implications are discussed

Affine convex body semigroups

In this paper we present a new kind of semigroups called convex body semigroups which are generated by convex bodies of R^k. They generalize to arbitrary dimension the concept of proportionally modular numerical semigroup of [7]. Several properties of these semigroups are proven. Affine convex body semigroups obtained from circles and polygons of R^2 are characterized. The algorithms for computing minimal system of generators of these semigroups are given. We provide the implementation of some of them

Study and analysis of the implementation of 4.0 technologies in the agri-food supply chain: A state of the art

Industry 4.0 is changing the industrial environment. Particularly, the emerging Industry 4.0 technologies can improve the agri-food supply chain throughout all its stages. This study aims to highlight the benefits of implementing Industry 4.0 in the agri-food supply chain. First, it presents how technologies enhance the agri-food supply chain development. Then, it identifies and highlights the most common challenges that Industry 4.0 implementation faces in agri-food’s environment. After that, it proposes key performance indicators to measure the advantages of this implementation. To achieve this, a systematic literature review was conducted. It combined conceptual and bibliometric analyses of 78 papers. As a result, the most suitable technologies were identified, e.g., Internet of Things, Big Data, blockchain and cyber physical systems. The most used indicators are proposed and the challenges of implementation were detected and classified in three groups, i.e., technical, educational and governmental. This paper highlights and exemplifies the benefits of implementing Industry 4.0 facing the lack of knowledge that exists nowadays. Moreover, it fulfils the gaps in literature, i.e., the lack of information about the implementation of technologies 4.0 or the description of the most relevant indicators for Industry 4.0 implementation. © 2021 by the authors.

In situ gamma-ray spectrometry (GRS) use for non-destructive archaeological exploration

Pre-print versionLandscape, Heritage and Paleoenvironment Laboratory, University of Santiago, Spain Geophysical prospection methods are used in archaeology to locate features of archaeological sites before excavation. Among geophysical methods, those mostly used in archaeology are seismic methods, electromagnetical surveys, and georadar. All of them allow assessing properties of soil, sediment and/or rock, providing cross section of soil properties that can be related to buried archaeological structures and objects. Gamma-ray spectrometry (GRS) is a technique used for different geological purposes including mineral exploration and mapping. However, it has not been applied in archaeology: the only study case known by the authors was successful (Moussa, 2001) but no later reports or more extensive studies have been found. In situ GRS is a non-destructive method that allows direct assessment of potassium-40 (40K), uranium-238 (238U) and thorium-232 (232Th) and daughter radionuclides of their decay chains on rock outcrops and soils. Such radionuclides are ubiquitous in most rocks and soils and the main causes of natural gamma radiation. The technique allows assessing their concentration in topsoil, being of potential use for archaeological exploration but two assumptions must be made: the archaeological buried objects must contain a different concentration of radionuclides than the surrounding sediment or soil, and they must be buried in the topsoil (25-30 cm depth). Thus, it is potentially applicable for exploration of shallow structures or objects. However, it does not provide cross -sections of the ground, but maps of the structures and objects buried. In this work, we have tested in situ GRS in an archaeological site that was partially excavated. In the site, remains of walls made of stone have been excavated, being buried in other parts of the site, but near the ground surface, being the top of the structures at 10-30 cm depth. We have tested in situ GRS in small parcel of 10 x 7 m, located beside nearby excavated areas which wall remains are partially buried in the studied parcel. The purpose of the study is to assess if the technique is reliable for the exploration of structures. Rocks used as building materials in the walls are mostly metamorphic rocks of very low radionuclide content with negligible 40K. However, the sediment that uries the structures contains significant amounts of K, U and Th radioisotopes. Results showed reliable results for surface exploration where shallow structures exist, despite the low radioactive content of the archaeological materials in the site.Este trabalho insere-se nas atividades do Projeto Lab2PT- Laboratório de Paisagens, Património e Território - AUR/04509 que tem o apoio financeiro da FCT/MCTES através de fundos nacionais (PIDDAC) e o cofinanciamento do Fundo Europeu de Desenvolvimento Regional (FEDER), refª POCI-01-0145-FEDER-007528, no âmbito do novo acordo de parceria PT2020 através do COMPETE 2020 – Programa Operacional Competitividade e Internacionalização (POCI).info:eu-repo/semantics/publishedVersio
