Journalism Handbooks of communication science ;, v. 19./ edited by Tim P. Vos.
No full textIn English.Includes bibliographical references and index.This volume sets out the state-of-the-art in the discipline of journalism at a time in which the practice and profession of journalism is in serious flux. While journalism is still anchored to its history, change is infecting the field. The profession, and the scholars who study it, are reconceptualizing what journalism is in a time when journalists no longer monopolize the means for spreading the news. Here, journalism is explored as a social practice, as an institution, and as memory. The roles, epistemologies, and ethics of the field are evolving. With this in mind, the volume revisits classic theories of journalism, such as gatekeeping and agenda-setting, but also opens up new avenues of theorizing by broadening the scope of inquiry into an expanded journalism ecology, which now includes citizen journalism, documentaries, and lifestyle journalism, and by tapping the insights of other disciplines, such as geography, economics, and psychology. The volume is a go-to map of the field for students and scholars--highlighting emerging issues, enduring themes, revitalized theories, and fresh conceptualizations of journalism.Vos, Tim P. -- Nerone, John -- Hanitzsch, Thomas -- Ward, Stephen J.A. -- Plaisance, Patrick Lee -- Witschge, Tamara / Harbers, Frank -- Lowrey, Wilson -- McNair, Brian -- Kitch, Carolyn -- Wanta, Wayne / Alkazemi, Mariam -- D'Angelo, Paul / Shaw, Donna -- Tandoc, Edson C. -- Belair-Gagnon, Valerie / Revers, Matthias -- Picard, Robert G. -- Mills, Anthony / Sarikakis, Katharine -- Phillips, Angela -- Gutsche, Robert E. / Rafikova, Alina -- Singer, Jane B. -- Nguyen, An / Scifo, Salvatore -- Thomas, Ryan J. -- Craft, Stephanie -- Hanusch, Folker -- Horvit, Beverly / Cortés-Martínez, Carlos A. / Kelling, Kimberly -- George, Cherian -- Karppinen, Kari -- Mislán, Cristina -- Sehl, Annika -- Ornebring, Henrik -- Heinderyckx, François -- Frontmatter -- Preface to Handbooks of Communication Science series -- Acknowledgements -- Contents -- 1.

Evaluating Citebase, an open access Web-based citation-ranked search and impact discovery service
No full textCitebase is a new citation-ranked search and impact discovery service that measures citations of scholarly research papers which are openly accessible on the Web, i.e. papers that are assessable continuously online. Other services, such as ResearchIndex, have emerged in recent years to offer citation indexing of Web research papers. In the first detailed user evaluation of an open access Web citation indexing service, Citebase has been evaluated by nearly 200 users from different backgrounds. The paper details the procedures used in the evaluation, and analyses the results of this study, which took place between June and October 2002. It was found that within the scope of its primary components, the search interface and services available from its rich bibliographic records, Citebase can be used simply and reliably for the purpose intended, and that it compares favourably with other bibliographic services. It is shown tasks can be accomplished efficiently with Citebase regardless of the background of the user. More data need to be collected and the process refined before it is as reliable for measuring citation impact of indexed papers. Better explanations and guidance are required for first-time users. Coverage is seen as a limiting factor, even though Citebase indexes over 200,000 papers from arXiv. Non-physicists were frustrated at the lack of papers from other sciences. The principle of citation searching of open access archives has thus been demonstrated and need not be restricted to current users. Since the evaluation, Citebase has become a featured service of the ArXiv physics eprint archives
Mitochondrial DNA methylation in placental tissue: a proof of concept study by means of prenatal environmental stressors
No full textWhile previous studies have demonstrated that prenatal exposure to environmental stressors is associated with mitochondrial DNA (mtDNA) methylation, more recent investigations are questioning the accuracy of the methylation assessment and its biological relevance. In this study, we investigated placental mtDNA methylation while accounting for methodological issues such as nuclear contamination, bisulphite conversion, and PCR bias. From the ENVIRONAGE birth cohort, we selected three groups of participants (n = 20/group). One group with mothers who smoked during pregnancy (average 13.2 cig/day), one group with high air pollutant exposure (PM2.5: 16.0 +/- 1.4 mu g/m(3), black carbon: 1.8 +/- 0.3 mu g/m(3)) and one control group (non-smokers, PM2.5: 10.6 +/- 1.7 mu g/m(3), black carbon: 0.9 +/- 0.1 mu g/m(3)) with low air pollutant exposure. DNA methylation levels were quantified in two regions of the displacement loop control region (D-loopandLDLR2) by bisulphite pyrosequencing. Additionally, we measured DNA methylation on nuclear genes involved in mitochondrial maintenance (PINK1, DNA2, andPOLG1) and assessed mtDNA content using qPCR. AbsoluteD-loopmethylation levels were higher for mothers that smoked extensively (+0.36%, 95% CI: 0.06% to 0.66%), and for mothers that were highly exposed to air pollutants (+0.47%, 95% CI: 0.20% to 0.73%). The relevance of our findings is further supported, asD-loopmethylation levels were correlated with placental mtDNA content (r = -0.40, p = 0.002) and associated with birth weight (-106.98 g, 95% CI: -209.60 g to -4.36 g for an IQR increase inD-loopmethylation). Most notably, our data demonstrates relevant levels of mtDNA methylation in placenta tissue, with significant associations between prenatal exposure to environmental stressors andD-loopmethylation.This work was supported by the Research Foundation Flanders [G082317N]; Research Foundation Flanders [N1518119].Janssen, BG (corresponding author), Hasselt Univ, Ctr Environm Sci, B-3590 Diepenbeek, Belgium.

Who Belongs? Immigrants, Refugees, Migrants, and Actions Towards Justice: A Conversation With Tim Wise
No full textTim Wise is an antiracist activist, essayist and author of seven books on racism, inequality and white privilege. He is among the most prominent anti-racist writers and educators in the United States. Over the past 25 years he has engaged audiences in all 50 states, at over 1000 college and high school campuses, at hundreds of professional and academic conferences, and to community groups across the country. While visiting Iowa State University Tim Wise interviewed with us to discuss Who Belongs? by providing a brief historical perspective of immigration, the current political climate, and the role of activism.</p

Whose Voice? Tim Crouch’s The Author and Active Listening on the Contemporary Stage
No full textThe essay discusses Tim Crouch’s recent play The Author (2009) in the context of active listening, audience participation, response and responsibility in contemporary theatre. It provides a critical engagement with the spectatorial experience of the piece so as to problematize the multiple uses of the physical medium of voice and speech in a contemporary play that delivers a fresh angle to narrativity and metatheatricality. At the same time, the essay probes the varied range of possibilities but also realistic extent of audience involvement in the play, tracing its deep textual contingencies to produce an overall understanding of the equally rewarding and precarious interrelationship between performance piece and audience.</p
