Displaced glances: we are nothing, anyone of us can lose control of our lives
No full textA través del análisis de una entrevista a una ciudadana cubana que ha vivido la crisis de la
COVID-19 en contexto español, este artículo trata de acercarse al sistema de creencias de una
persona migrada en relación con los efectos de la pandemia en el país de destino. Partiendo de
sus vivencias en el país de origen, se realiza un recorrido por las consecuencias que la
situación actual ha tenido en su vida personal y laboral, así como en su relación con la
sociedad receptora. Se trataría de identificar, y valorar, el peso que potenciales variables como
la raza, el género o la clase pueden jugar en situaciones de crisis como la vivida en contextos
migratorios de llegada.By analyzing an interview with a Cuban citizen that has experienced the Covid-19 crisis within
a Spanish context, this article tries to examine the belief system of an immigrant with respect to
the pandemic’s effects at the destination country. Starting from the lived experiences of the
immigrant’s country of origen,we can examine the consequences that the currrent situation has
had on the participant’s personal and work life as well as in its relationship with the host
country. This article will identify and validate the impact that potential variables such as race,
gender and class can play in crisis situations as in the lived experiences of migrant contexts
Influence of air-entraining agent and freeze-thaw action on pore structure in high-strength concrete by using CT-Scan technology
No full textIn this work, the effects caused by both the amount of air-entraining agent (AEA) and freeze-thaw cycles on microstructure of high-strength concrete have been analyzed. For this purpose, five series of concrete specimens have been manufactured, each of them containing a different amount of AEA. Then, all series have been subjected to up to 300 freeze-thaw cycles. In addition, the specimens have been analyzed using a computed tomography (CT) scan device at pre-defined freeze-thaw cycles and all data have been processed with digital image processing (DIP) software.
The results reveal, on the one hand, that the quantity of AEA has a greater influence on pore structure, and additionally the freeze-thaw action only slightly modifies the pore structure. As AEA increases, a progressive rise of the porosity and the number of pores is observed up to a maximum value. Next, a decrease is noticed. Moreover, there is not a linear relation between porosity and AEA. Furthermore, as AEA increases, a variation of its size and shape is observed. Alternatively, the effect of freeze-thaw cycles is more complex and does not show a monotonous tendency. The results reveal that the first 50 freeze-thaw cycles have the strongest influence on pore structure, observing a decrease in porosity. For the rest of the cycles, the porosity increases progressively resulting, after 300 freeze-thaw cycles, in a slightly lower porosity in almost all series than in those presented at the beginning. Hydration of unhydrated cement particles alongside with microcracking act as opposite performances during the freeze-thaw cycles. Therefore, this can suggest that, under these conditions, freeze-thaw action is not able to damage significantly the microstructure of concrete.
The results show that the series with a lower AEA content show a better behavior under freeze-thaw cycles. In this case, the specimens exhibit a lower porosity and a higher level of small pores, and the pores evince a more elongated shape. All these features lead to a more impermeable concrete and, therefore, with a better performance under freeze-thaw cycles.The authors are grateful for the financial support from the Ministerio de Economía y Competitividad, PID2019-110928RB-C32, Spain
A bestia buena, vara y espuelas: historia cultural del maltrato estudiantil
No full textEl abuso y maltrato a los novatos es tan antiguo como las propias universidades. Aún hoy se sufren estos comportamientos violentos y humillantes bajo la disculpa de tratarse de una tradición. Este artículo revisa los orígenes históricos de tales maltratos a partir de la confluencia de elementos institucionales ligados al origen gremial de las universidades medievales, j unto con otros provenientes de las viejas violencias culturales europeas. A partir de una perspectiva metodológica interdisciplinar, el trabajo analiza informaciones históricas, obras literarias y materiales etnológicos con particular atención a las manifestaciones rituales y festivas propias de la cultura popular y, especialmente, de la juventud como edad cultural percibida semisalvaje y pronta a la violencia.The abuse and mistreatment, or hazing, of first-year students, is as old as universities themselves. These violent and humiliating behaviors are today legitimated by their longevity, presented as traditions. This article reviews the historic roots of hazing as constituted by the confluence of institutional elements–tied to the guild roots of medieval universities –and factors derived from long-standing European violent cultural practices. Using an interdisciplinary methodological perspective, the text analyzes historical information, literary works, and ethnological materials, paying special attention to the ritual and festive manifestations of popular culture, and especially, of youth, as a period culturally perceived and defined as semi savage and prone to violence
Porous aromatic polyamides the easy and green way
Get PDFWe prepared microporous aramid films through a simple, inexpensive and green way, using ionic liquids (IL) as porosity promoters. Commercial poly(m-phenylene isophthalamide) (MPIA) films with different IL proportions were prepared, and then microporous films were obtained by removing the IL in distilled water. Microporous films presented density values between 0.34 and 0.71 g⋅cm−3 (around five times lower to commercial MPIA), with a homogeneous and controlled cellular morphology dependent on the proportion of the IL, showing cell sizes in the microcellular range (radii between 1 and 8 µm). Thermal, mechanical and electrical properties (specifically ionic conductivity) of the aramid films were analyzed to evaluate the influence of the IL proportion. Finally, it was observed that the MPIA/IL system presented a reversible thermally induced phase-separation process around 60 °C, which was characterized through AFM-Raman images and spectra, together with the variation of the ionic conductivity.FEDER (Fondo Europeo de Desarrollo Regional) and both the Spanish Agencia Estatal de Investigación (MAT2017-84501-R) and the Consejería de Educación-Junta de Castilla y León (BU306P18
Efectos de un programa de entrenamiento en mindfulness y autocompasión sobre el estado emocional de médicos y enfermeras residentes de atención familiar y comunitaria y sus tutores: proyecto MINDUUD
Get PDFLos profesionales de la salud presentan en la actualidad unos niveles altos de ansiedad y estrés. En concreto en Atención Primaria, cerca del 40 %. Numerosos estudios sugieren la necesidad de proporcionar al profesional herramientas que le ayuden a un mejor afrontamiento de la realidad y autorregulación emocional. Existen ya evidencias de los beneficios de los programas de entrenamiento en Mindfulness (estar presente, concentración en la tarea, sin divagar, sin apego ni rechazo) y Autocompasión (Bondad hacia uno mismo, humanidad compartida y atención plena/mindfulness). La combinación de ambos reduce los niveles de estrés y ansiedad de los profesionales de la salud, a la vez que mejoran la empatía y la calidad de la asistencia que recibe el paciente. El ensayo clínico, eje de esta tesis, consistió en una intervención sobre 6 Unidades Docentes de formación MIR y EIR (Córdoba, Jaén, Almería, Ponferrada, Zaragoza y Burgos). Dos Unidades Docentes (UD) fueron asignadas al Grupo Experimental (GE1) de formación estándar en MBSR de 8 semanas (complementada con Autocompasión), otras 2 UD al formato abreviado de 4 semanas (GE2), y las otras 2 UD actuaron como Grupo Control. En total se incluyeron 112 participantes
Análisis táctico del field goal en baloncesto: implicaciones teóricas y aplicaciones prácticas
Get PDFEn el baloncesto, como deporte de colaboración-oposición, numerosos factores inciden en el resultado, pero el tiro de campo es sin duda el gesto y aspecto decisivo por excelencia. Esto es debido a que, junto con el tiro libre, es la forma de consecución de puntos, y por tanto, un medio indispensable para la victoria.
El presente trabajo de investigación expone el problema, los análisis y los resultados de la investigación llevada a cabo para conocer y explicar la influencia de las variables intervinientes en las dimensiones tácticas del tiro de campo, incluyendo la perspectiva de género, con el propósito de contribuir a mejorar la teoría y práctica del baloncesto.

The single-member company, societas unius personae or «quasi societas»?
No full textEl reconocimiento legal de la sociedad unipersonal es una
realidad incuestionable en nuestros días, otra cosa es que su denominación
sea la más apropiada, pues la locución «sociedad unipersonal» encierra una
digresión terminológica. De todos modos, su versión latina: societas unius
personae no hubiera tenido cabida en el ordenamiento jurídico romano pues
carecería de un significado técnico-jurídico preciso. Por ello, el objetivo del
presente trabajo consiste en elevar una propuesta de denominación, con
independencia de su aceptación doctrinal y uso actual, para la debatida
cuestión de la unipersonalidad societaria, desde la óptica jurisprudencial
romana.Legal recognition of the single-member company is these
days an unquestionable reality, although another thing is whether its denomination is the most appropriate, as the phrase «single-member company» encloses
a terminological digression. In any event, its Latin version: societas unius
personae could not have fitted in the Roman legal order as it would have lacked a precise legal-technical meaning. Therefore, the objective of the present study consists in establishing a proposal for its denomination, regardless
of its doctrinal acceptation and actual use, for the disputed question of the
unipersonality of the firm, from the Roman jurisprudential viewpoint
