A Historical Analysis of Media Practices and Technologies in Protest Movements : A Review of Crisis and Critique by Anne Kaun
2017
Dr. Anne Kaun’s book, <em>Crisis and Critique: A Brief History of Media Participation in Times of Crisis</em> (London: Zed Books, 2016, 131 pp., ISBN: 978-1-78360-736-5), is a concise but comprehensive analysis of the changing media practices and technologies in protest movements. The book overviews the topic within the context of major economic crises and scrutinises three richly detailed case studies in the United States: (a) the unemployed workers’ movement during the Great Depression in the 1930s, (b) the tenants’ rent strike movement of the early 1970s, and (c) the Occupy Wall Street movement following the Great Recession of 2008. Kaun begins her book with an introduction t…
Immunoaffinity purification and characterization of mitochondrial membrane-bound D-3-hydroxybutyrate dehydrogenase from Jaculus orientalis.
2008
Abstract Background The interconversion of two important energy metabolites, 3-hydroxybutyrate and acetoacetate (the major ketone bodies), is catalyzed by D-3-hydroxybutyrate dehydrogenase (BDH1: EC 1.1.1.30), a NAD+-dependent enzyme. The eukaryotic enzyme is bound to the mitochondrial inner membrane and harbors a unique lecithin-dependent activity. Here, we report an advanced purification method of the mammalian BDH applied to the liver enzyme from jerboa (Jaculus orientalis), a hibernating rodent adapted to extreme diet and environmental conditions. Results Purifying BDH from jerboa liver overcomes its low specific activity in mitochondria for further biochemical characterization of the e…
kLa MEASUREMENT IN BIOREACTORS
2010
For accurately measuring kLa in bioreactors the dynamic pressure method (DPM) was introduced by Linek et al. (1993). In this work a simplified version of the same method is discussed. With respect to the original DPM, the simplified version greatly simplifies data treatment. In fact final constant slope observable in the usual semi-log diagram of residual driving force versus time may be simply corrected to obtain the real kLa value with negligible inaccuracy. Experimental data obtained on a lab-size stirred tank reactor confirm all model predictions, including the feature that the adoption of large pressure changes may lead to a better accuracy.
Problemy współczesnej genologii medialnej
2020
The paper is an attempt at clarifying the object of research into media genology, distancing itself from literary studies genology. In the era of convergence of mass media, we can observe a progress in the blurring of the border between information and journalism, which consequently changes the contemporary communicative convention. As a result, information services are often degraded and the sense of implementing ‘traditional’ indicators of mass media genres is questioned. The change of communicative convention in contemporary mass media requires, above all, the use of cultural context for its analysis, as it determines the methods of creating messages and means of receiving them. It also …
Pirandello e Gombrowicz – La presenza teatrale pirandelliana nei drammi gombrowicziani di Karol Karp (review)
2014
Veronica Chiarenza (Università degli Studi di Roma “La Sapienza”) Recensione su Pirandello e Gombrowicz - La presenza teatrale pirandelliana nei drammi gombrowicziani di Karol Karp Pirandello e Gombrowicz - La presenza teatrale pirandelliana nei drammi gombrowicziani di Karol Karp si muove nell’ambito di un dualismo e di elementi di vicinanza tra i due autori. Il volume procede attraverso un movimento “geografico” ben definito – dalla Sicilia di Pirandello alla Polonia di Gombrowicz – e concettuale – da un’immagine più ampia dei temi tipici di Pirandello sino al loro riscontro specifico in tre drammi scritti da Gombrowicz. Karp analizza il rapporto tra i due scrittori con grande diligenza e…
Prácticas de recursos humanos y su impacto en los resultados de innovación: una revisión teórica
2013
El presente artículo tiene como objetivo la realización de una revisión teórica con la finalidad de identificar las prácticas de Recursos Humanos más analizados respecto a los resultados de innovación y, como resultado, poner de manifiesto otras variables no consideradas hasta la fecha pera que también tengan incidencia en dicha relación. Así pues, autonomía, participación, formación, sistemas de recompensas, trabajo en equipo, reclutamiento y selección, además del desarrollo de carrera profesional, afectarían positivamente los resultados de la innovación a través de la creatividad y la gestión del conocimiento. La estructura y cultura organizativa jugarían un papel moderador en esta relaci…
Semiótica da cidade: corpos, espaços, tecnologias
2015
Resumo:A cidade é feita de espaços, corpos, tecnologias. A semiótica tem estudado há tempos todos estes três fenômenos de significação. Todavia, o estudo semiótico do espaço urbano quase nunca foi articulado pela semiótica dos objetos técnicos, nem pela do corpo. Entrelaçar estes três âmbitos, como este artigo busca fazer, aparece, portanto, como um gesto teórico tão urgente quanto necessário. Nestas páginas analisa-se um velho desenho animado de Walt Disney em que o personagem de Pateta muda radicalmente os próprios programas de ação e paixão, condicionado por estar no espaço urbano, como pedestre ou automobilista. Um ator, dois actantes, e consequentemente, dois espaços de significação di…

A new Three Color Marker for TCP flows
2004
In Differentiated Services networks, packets may receive a different treatment according to their Differentiated Services Code Point (DSCP) label. As a consequence, packet marking schemes can be devised to differentiate packets belonging to a same TCP flow, with the goal of improving the experienced performance. This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, which relies on three different service classes, provided by the DiffServ network. The scheme provides protection of vulnerable packets in the TCP flows and adaptivity through "probes" packets. The performance have been evaluted in a traffic scenario composed of TCP flows with different …
Spaced learning and innovative teaching: school time, pedagogy of attention and learning awareness.
2016
AbstractCurrently, the ‘time’ variable has taken on the function of instructional and pedagogical innovation catalyst, after representing-over the years-a symbol of democratisation, learning opportunity and instruction quality, able to incorporate themes such as school dropout, personalisation and vocation into learning. Spaced Learning is a teaching methodology useful to quickly seize information in long-term memory based on a particular arrangement of the lesson time that comprises three input sessions and two intervals. Herein we refer to a teachers’ training initiative on Spaced Learning within the programme ‘DocentiInFormAzione’ in the EDOC@WORK3.0 Project in Apulia region in 2015. The…
