Hip and wrist accelerometers showed consistent associations with fitness and fatness in children aged 8‐12 years
2020
Aim. Physical activity (PA) has traditionally been measured wearing accelerometers on the hip, but they are increasingly being worn on the wrist. We compared hip and wrist accelerometers with regard to their acceptability and any associations between PA and fatness and fitness. Methods. This cross‐sectional study comprised 103 children aged 8‐12 years (62% boys) who participated in the ActiveBrains trial by the University of Granada, Spain, in 2014‐2016. The children wore both ActiGraph GT3X+ hip and wrist accelerometers round the clock for seven days. The acceptability of both placements was evaluated by a questionnaire, while the children' fat mass index, waist circumference, and cardiore…
From ‘no dogs here!’ to ‘beware of the dog!’ : restricting dog signs as a reflection of social norms
2019
Signs in public space reflect ‘normalcy’ in a community. The authors ask what restricting signs tell us about a society? In order to explore the system and variation in the ways dog signs manifest different norms and control, they compare two different data sets: dog signs in a Northern European town, Jyväskylä in Finland, and two Eastern European villages in Romania. They apply a qualitative methodology based on visual communication, geosemiotics and linguistic landscape studies. The focus of the article is on the resources of addressing and the visual semiotics of the image. The investigated communities seem to create a complementary distribution of what they regulate that is also displa…
Il ruolo di Google Earth e OpenStreetMap nella partecipazione civica al processo decisionale
2013
Lo sviluppo dei GIS, delle mappe informatiche e di strumenti di georeferenziazione condivisi via web è un fenomeno di notevole importanza nel panorama delle trasformazioni culturali odierne, le quali riguardano non solo la rappresentazione dello spazio ma soprattutto la sua interpretazione e il modo in cui viene vissuto e percepito dai suoi abitanti. Ad uno spazio fisico sempre più frammentato corrisponde uno spazio virtuale policentrico, costruito a più livelli da utenti che sono sia fruitori che produttori di informazione. Un esempio di questo processo è il software Google Earth: da un lato esso veicola la diffusione di una delle infinite, possibili immagini virtuali dello spazio, che nel…
Materiali per una crisi: teorema del serializzante nell’epoca della video-guerra civile
2015
Starting from a brief de-functionalizing analysis of the info-spectacular society, the essay explores the pervasiveness of the repressive-disciplining forms which are increasingly affecting the behaviors of the individualities in the info-spherical dominion. In particular, the paper focuses on what will be defined the “serializing” and highlights some repetitive-determinant aspects of the video-seriality that are involved in the processes of “over-codification” imposed by the infosphere on the anthropo-sphere. In order to define the serializing will be taken in exam both the possible evolutions of the Gelassenheit and the “dispositiviness” imposed by info-securitarian post- democracies thro…
Webcam based display calibration
2012
International audience; We present an automatic method for measuring the tone response curve of display devices based on visual methods, where the eye is replaced by an end-user, uncalibrated camera, such as a webcam. Our approach compares a series of halftoned patches of known covering ratio with a continuous series of tone patches for each ratio. Both patches are shot by a camera that is used as a virtual eye to evaluate the luminance difference. By an iterative process, the continuous tone value is adjusted while compared with the perceived level of the halftoned patch. When the camera does not see any difference between the patches or a minimal difference, the luminance level of the con…

The Trope of Sight in North American Whiteness Studies
2017
The trope of sight has been the central metaphor in North American whiteness studies sińce its very inception, that is, already before whiteness studies emerged as a separate field of study. The centrality of the trope stems not only ffom a particular applicability of the sight metaphor to render subject-object relations, but also ffom the unique presence of “sight” in the very relations between racial groups in the United States, in particular Alfican Americans, and whites. Originally, minorities were cast as objects of the gaze, while white people as subjects of the gaze, exercising the power to look, survey and pass judgment. Apart ffom exposing practices of looking employed by whites, w…
Synteza i właściwości fizykochemiczne ftalocyjaniny manganu
2017
Ftalocyjaniny to organiczne związki chemiczne, które uzyskuje się jedynie na drodze syntezy chemicznej. Stanowią one jednak analogi strukturalne porfiryn, które naturalnie występują w przyrodzie, m.in. w takich cząsteczkach jak witamina B12 czy chlorofil. Obszerne badania dotyczące kompleksów ftalocyjanin wynikają z budowy tych związków, ponieważ cząsteczkę ftalocyjaniny można modyfikować na bardzo wiele sposobów. Wpływa to na różnorodność zastosowań ftalocyjanin, m.in. w urządzeniach elektronicznych, fotowoltaicznych, jako fotosensiblilizatory, barwniki i pigmenty. Kompleksy ftalocyjanin z takimi metalami jak mangan czy kobalt są intensywnie badane ze względu na ich interesujące właściwośc…
W więzieniu widoczności medialnej. Rozważania o mikropolityce w "ponoptykonicznej rzeczywistości"
2017
W dobie telefonów komórkowych z dostępem do Internetu, wyposażonych w cyfrowe aparaty fotograficzne, „fotoreporterem” może zostać każdy. Dziś polityk nie tylko musi potrafić dobrze się zaprezentować, ale będąc ciągle narażonym na upublicznienie, kontrolować każdy swój gest i ważyć każde słowo. Każdy błąd czy gafa szybko może przerodzić się w poważny kryzys zagrażający wizerunkowi aktora politycznego. Na ciągłą widoczność narażone są nie tylko najważniejsze osoby w państwie, ale wręcz każdy. Co równie istotne, współczesna polityka oparta jest na ciągłej medialnej widoczności. Aktywna obecność na portalach społecznościowych staje się równie ważna, o ile nie ważniejsza od tego, kto i jak głoso…
Videowikis for improved problem-based collaborative learning: Engaging information systems science students
2013
The contemporary era of social media and web 2.0 has enabled a bottom-up on-line collaborative approach with easy content creation and subsequent knowledge sharing. The technically literate students of today and the changes in pedagogy towards a user-centred approach, where learners engage in the learning process by constructing new ideas and concepts based on their current or past knowledge facilitate the use of social media in learning environments. This paper describes the combination of a wiki and screen capture videos as a complementary addition to conventional lectures in an information management and information systems development course. The basis for our approach was collaborative…
