Situando cientistas com posições de gênero não normativas no sistema nacional de ciência e tecnologia colombiano

Os estudos de gênero e ciência na América Latina questionaram as estruturas desiguais do campo científico tomando como principal eixo de análise uma certa ideia homogênea das mulheres cientistas em oposição a seus colegas homens. Desde estas leituras permaneceram invisíveis questões étnico-raciais e de sexualidade que também configuram o lugar marginal do feminino na ciência. O estudo centrou-se no caso das cientistas colombianas com posições de gênero não normativas, particularmente marcadas por experiências raciais, como a de ser negras ou indígenas, ou pelas experiências de minoria com respeito à sua sexualidade, como ser lésbicas, com o propósito de analisar suas narrativas de autoposicionamento diante do sistema colombiano de ciência e tecnologia por parte destas cientistas. Metodologicamente, estas narrativas foram coletadas através de entrevistas de caráter etnográfico a 19 cientistas em diferentes regiões do país. Os resultados obtidos revelam que o campo científico está atravessado pelo gênero, de maneira ambígua. O estudo conclui que estas cientistas se percebem à margem da estrutura de prestígio que caracteriza o sistema de ciência, mas também posicionam seu trabalho reconhecendo que suas marcas minoritárias reconfiguram o ethos científico através de uma ética do cuidado particular.Los resultados obtenidos revelan que el campo científico está atravesado por el género, de manera ambigua.

Gender and science studies in Latin America have questioned the unequal structures of the scientific field in the region using as analytical pivot a particular and homogeneous idea of women scientist as opposed to men scientist. From these analytical approaches aspects such as ethnicity, race and sexuality, which are central to the shaping of the feminine condition as something marginal to the scientific field, have become invisible. In this study we focus on the case of Colombian women scientist whit non-normative gender positions shaped by experiences of racialization such as being black or indigenous, or experiences of minoritization in relation to their sexuality such as being lesbian, with the purpose of analyzing their narratives of self-positioning in relation to the Colombian national system of science and technology. Methodologically these narratives were collected through ethnographic interviews to 19 women scientists from different regions of the country. The results reveal that science and technology fields are gendered in ambiguous ways. The study concludes that these women scientists see themselves as marginal to the structure of prestige that characterizes the system; but they also position their work by acknowledging that their minority marks reshape the scientific ethos through a particular ethics of care

Peer Victimization in Overweight Adolescents and Its Effect on Their Self-Esteem and Peer Difficulties

This study has three objectives: to examine whether adolescents who perceive themselves as overweight differ from others in terms of offline victimization at school, cybervictimization, self-esteem, and difficulties relating to peers; to examine the possible effects of offline and cybervictimization on self-esteem and difficulties relating to peers; and to examine the possible moderating role of perceiving oneself as overweight on those effects. Previously validated questionnaires were applied to a sample of 3145 adolescents in Asturias (Spain). Descriptive, inferential, correlational, and structural equation analyses were performed. Adolescents who perceived themselves as overweight reported being victims of both offline victimization and most forms of cybervictimization to a greater extent than those who did not perceive themselves as overweight. They also reported lower self-esteem and more peer difficulties (shyness or social anxiety). In both groups of adolescents, victimization and cybervictimization were correlated with each other, both types of victimization had direct, negative effects on self-esteem, and self-esteem in turn had a direct, negative effect on peer difficulties. Furthermore, offline victimization had a direct, positive effect on peer difficulties. Perceiving oneself as overweight moderated the effect of self-esteem on peer difficulties. In adolescents perceiving themselves as overweight, low self-esteem was a stronger risk factor of peer difficulties than in the rest of the adolescents. With high overall self-esteem there were no significant differences in peer difficulties between the adolescents perceiving themselves as overweight and the rest of the adolescents

El efecto de la actividad física en la calidad del sueño. Revisión sistemática

El objetivo principal de este estudio determinar cómo la práctica de la actividad física influye en la calidad del sueño de la población adulta sana mediante la revisión de la literatura científica reciente y las evidencias empíricas acumuladas. Debemos tener en cuenta que el sueño es un proceso fisiológico esencial con importantes funciones de recuperación del metabolismo y del tejido orgánico. a medida que aumenta la edad, se producen cambios cuantitativos y cualitativos que se relacionan directamente con un aumento en la prevalencia de los trastornos del sueño. En cuanto en referencia a la prevalencia e incidencia, los trastornos del sueño en España afectan a una de cada cinco personas, siendo más predominante en mujeres que en hombres. a nivel mundial, más de la mitad de los adultos están diagnosticados con algún trastorno del sueño, de los cuales entre el 20% y el 40% reportan insomnio. Queremos ver si la actividad física mejora en la calidad del sueño, ya que teniendo en cuenta los estudios previos que relacionan sueño y deporte, hoy en día, no hay suficientes evidencias que apoyen que la realización de un mínimo de actividad física podría incidir sobre la calidad del sueño. Para ello se realizó una revisión sistemática de los últimos cinco años sobre cómo afecta la af en la calidad del sueño durante el mes de marzo de 2023. Para ello, se tuvo en cuenta el procedimiento propio del sistema prisma. Consultando una única base de datos, Pubmed

From the wound to the bench:A study of wound-colonising bacteria and their interactions

This research was directed to define common protein and gene expression patterns in wound-colonizing bacteria, with special focus in the opportunistic bacterium Staphylococcus aureus. To this end, the studies approach was based on a chronic wound model that exists in epidermolysis bullosa. The analysis shows that S. aureus can stably coexist in a community as a result of different biochemical and metabolic mechanisms that allow it to adapt to a specific environment. S. aureus shows a cooperative character towards other pathogens that confer it the benefit to share resources. Interestingly, S. aureus seems to have taken advantage of the features displayed by its neighbours without the need of expressing (reduced genomic inventory) those features itself. In vitro co-culturing of S. aureus with Klebsiella oxytoca and Bacillus thuringiensis, not only decreased the expression of cytoplasmic proteins, but also the expression of genes related to virulence. Furthermore, proteins that were originally considered to be restricted to the cytoplasm were also identified extracellularly, which may be important for virulence enhancement and invasive disease. These observations were validated with the Galleria mellonella animal model experiments; where reduced mortality was registered upon co-infection with S. aureus and K. oxytoca. The helicopter view of wound-resident bacteria in vitro led this research into the exploration of the staphylococcal gene expression in situ. Indeed, the effects of the microbiome over S. aureus in the wound were observed and several genes that were found to be expressed in vitro were also expressed in situ

Reducción por adquisición de empresa familiar en el Impuesto sobre Sucesiones = Reduction for acquisition of family business in Inheritance Tax

[ES] Las empresas familiares en España tienen un gran peso económico, de ahí que el legislador pretenda remover los obstáculos existentes para asegurar su supervivencia intergeneracional. En concreto, el Impuesto sobre Sucesiones supone un problema para muchas de estas empresas al no poder hacer frente a su pago debido a una carencia de liquidez, por lo que las Comunidades Autónomas han establecido numerosos beneficios fiscales para intentar asegurar la continuidad de dichas empresas. El fin último de estos beneficios es garantizar que las empresas continúen perteneciendo a la misma rama familiar, es por eso que se aplican a aquellos sujetos pasivos que tienen un grado de parentesco cercano con el causante

Paraules amb valor de línia : el diàleg a través del dibuix

Paraules amb valor de línia. El diàleg a través del dibuix sorgeix a partir de les inquietuds vers l’eina que probablement més hem fet servir al llarg dels anys quan volem fer referència o parlar de l’arquitectura: el dibuix. Sorgint com a eina clau i essencial per la transmissió de l’ideari particular, podríem arribar a dir que el dibuix funciona com un llenguatge. Llenguatge el qual es pot comprendre universalment, sense necessitat de cap altre recurs, i adaptable a qualsevol situació o necessitat. Partint d’aquesta base, posant la mirada en com el dibuix ens facilita una relació amb l’entorn, em qüestiono: què genera la interpretació d’un dibuix? El dibuix és un llenguatge, però pot, per ell mateix, originar qüestions en altres recursos lingüístics? Quines paraules ens generen les línies d’un dibuix? Pot un dibuix conversar?Words with linestyles, the dialogue through a drawing emerges from the inquisitiveness related to the probably most used tool among many years when we want to talk about architecture: the drawing. Emerging as a key point for our own ideologies transmission, we could say that a drawing works as a language. It can be understood globally, with no need of any other resource, and adaptable to any situation or need. On that basis, and focusing on how a drawing can get a relation with its surroundings, I wonder: what does a drawing’s interpretation create? A drawing is a language, but can it lead to questions in other languages on its own? Which words are generated by a drawing’s line? Can a drawing talk

Petrological Study as a Tool to Evaluate the Degradation of Speleothems in Touristic Caves, Castafiar de Ibor Cave, Caceres, Spain

In Castafiar cave the surface of most of the speleothems present dissolution and corrosion features. In touristic caves, this process has usually been related to the acidification of the atmospheric moisture caused by C02 from the breath of visitors. However, in Castafiar cave the process of corrosion has been also observed in rooms that are not visited by tourists. Petrological studies were carried out in the speleothems affected by surface corrosion in Castafiar cave. The results indicate that this process occurs not only at present time, but over a period of thousands of years, as evidenced by the presence of corrosion lines inside and on the surface of the speleothems. All this and the fact that Castafiar cave recovers very quickly from changes in the environmental parameters, indicates that the dissolution-corrosion process is slow and hence it is not related to the presence of visitors

Micritización de espeleotemas en ambiente meteórico vadoso (Cueva de Castañar de Ibor, Cáceres)

The aragonite and calcite speleothems of the Castañar de Ibor Cave show white and matt coatings that formed by micritization and dissolution of the initial crystals. These processes are also recognised in the inner part of the speleothems. Either in the inner or outher parts the result is the lost of brightness and transparency of the speleothems. Petrographically these coatings are seen as lines of micrite liked to dissolution processes that probably occurred because of the circulation of undersaturated fluids within the cave. At the moment no organic structures have been recognised in relation to the micritizated areas, indicating very probably that the process was inorganically driven
