Systematic reproduction and distribution, duplication of any material in this paper for a fee or for commercial purposes, or modification of the content of the paper are prohibited. The X-IFU instrument of the ATHENA mission requires a set of thermal filters to reduce the photon shot noise onto its cryogenic detector and to protect it from molecular contamination. A set of five filters, operating at different nominal temperatures corresponding to the cryostat shield temperatures, is currently baselined. The knowledge of the actual filter temperature profi…
Microscopic investigations of homogeneous nucleation in charged sphere suspensions.
2005
We studied the homogeneous nucleation kinetics of an aqueous suspension of charged colloidal spheres under de-ionized conditions. Samples of equilibrium crystalline structure were shear molten and the metastable melt left to solidify after cessation of shear. At low particle number densities n, corresponding to low metastability of the melt, nucleation was monitored directly via video microscopy. We determined the nucleation rates gamma(t) by counting the number of newly appearing crystals in the observation volume per unit time. Using a suitable discrete adaptation of Avrami's [J. Chem. Phys. 7, 1003 (1939); ibid.8, 212 (1940); ibid.9, 177 (1941)] model for solidification via homogeneous n…
Adicción a la pornografía: interferencia atencional y gravedad del consumo
2019
Introducción: El aumento del uso de las Tecnologías de la Información y la Comunicación (TICS) e Internet en nuestra sociedad ha potenciado la aparición de nuevas formas de adicción. Una de las más relevantes por sus implicaciones sociosanitarias sería la adicción al cibersexo, y más en concreto, el visionado excesivo de pornografía online. Numerosos estudios apuntan que, en determinadas personas, el visionado de pornografía puede sobrevenir excesivo e incontrolado, generando graves problemas en las diferentes áreas de la vida. Por ello, es importante explorar aquellos factores que actúan como predisponentes o mantenedores de este problema. Se postula que uno de ellos podría ser la capacida…
Homework practices: role conflicts concerning parental involvement
2016
ABSTRACTThis article on hand discusses results of an ethnographic study which aims to perform a detailed description of practices of doing homework in a domestic environment. Based on the international state of research, first the question and the methodical approach will be explained, subsequently the role conflicts and stress ratios developed while doing homework in a family environment will be presented on the basis of two contrasting cases. To conclude, the homework-linked intrusion of school into familiar surroundings, regarding the parental involvement in contradictory requirements, will be analysed.
Establishing Video Game Genres Using Data-Driven Modeling and Product Databases
2015
Establishing genres is the first step toward analyzing games and how the genre landscape evolves over the years. We use data-driven modeling that distils genres from textual descriptions of a large collection of games. We analyze the evolution of game genres from 1979 till 2010. Our results indicate that until 1990, there have been many genres competing for dominance, but thereafter sport-racing, strategy, and action have become the most prevalent genres. Moreover, we find that games vary to a great extent as to whether they belong mostly to one genre or to a combination of several genres. We also compare the results of our data-driven model with two product databases, Metacritic and Mobyga…
Mujeres zapatistas y producción videográfica en Chiapas
2018
Los primeros años de la rebelión zapatista coincidieron con la emergencia en México de un sector videográfico independiente, posibilitado por las nuevas tecnologías de grabación y edición, e inspirado en la lucha chiapaneca con sus redes de comunicación y solidaridad nacional e internacional. Antecediendo la era del Web 2.0 y las actuales redes sociales digitales, la producción videográfica sobre y desde el zapatismo fue una herramienta importante para la visibilización del conflicto y también de las transformaciones dentro de las comunidades chiapanecas, entre otras la autonomización y protagonismo de las mujeres. Este artículo explora la primera década de producción videográfica en torno …
“Cute Goddess is Actually an Aunty”: The Evasive Middle-Aged Woman Streamer and Normative Performances of Femininity in Video Game Streaming
2022
In this paper the focus is on the representations of “middle-aged” or “aging” women streamers in western media. I analyze discussions in Western online media around a case of Chinese DouYu live-streamer. “Qiaobiluo Dianxia,” as her streamer name goes, became a topic in Western media after a glitch in her live stream revealed her to be a middle-aged woman, rather than young woman she was assumed to be. The discussions are analyzed with critical discourse analysis. It is argued that the aging bodies of women, both their presence and absence, should be read and understood through toxic gaming culture and geek masculinity and the hegemonic discourse they constitute.
Associations between Sports Videogames and Physical Activity in Children
2022
Abstract Objective: The aim of the study was to examine the associations of sports video gaming behaviour in the sociological concept of Physical Activity Relationships (PAR) and to see if sports video gaming differs by gender. Methods: A convenience sample of children between 11–12 years of age (n = 114) from three Finnish regions completed a questionnaire on perceptions of their video gaming and physical activity habits. Differences by gender were tested by contingency tables, and blockwise binary logistic regressions were used to examine the strength of association with physical activity behaviour in PAR. Results: Almost all girls had low importance to video gaming and over two thirds (7…
Città Invisibili of Teatro Potlach: A Journey to Rediscover Our Cultural Heritage
2017
Città Invisibili is a multidisciplinary art project made by the Italian company Teatro Potlach. Compared to the canonical theatrical performances, Città Invisibili, being in its essence a site-specific performance, interacts with the place where it grows. With the project, the Italian group builds next to the existing space of the place (physical space and memory space) other two spaces, the space of the staging and the space of the performer, using different materials, in particular cloths and video projections. Moreover Teatro Potlach conducts a historical, anthropological and social research trying to bring out the latent memory of places. All these interventions bring out from the place…
Cytochrome c is released in a single step during apoptosis
2005
Release of cytochrome c from mitochondria is a central event in apoptotic signaling. In this study, we utilized a cytochrome c fusion that binds fluorescent biarsenical ligands (cytochrome c-4CYS (cyt. c-4CYS)) as well as cytochrome c-green fluorescent protein (cyt. c-GFP) to measure its release from mitochondria in different cell types during apoptosis. In single cells, the kinetics of cyt. c-4CYS release was indistinguishable from that of cyt. c-GFP in apoptotic cells expressing both molecules. Lowering the temperature by 7 degrees C did not affect this corelease, but further separated cytochrome c release from the subsequent decrease in mitochondrial membrane potential (DeltaPsi(m)). Cyt…
