Investigation of cell fate decision in Schizosaccharomyces pombe by ncRNA annotation and statistical analyses

Studies in the fission yeast Schizosaccharomyces pombe (S. pombe) have done much to inform the view of heterochromatin and its control by the RNA interference (RNAi) machinery. Using cDNA synthesised from poly(A)-enriched RNA samples, numerous novel ncRNA loci were discovered, and the 50 and 30 ends of many other genes were refined in previous studies. Although some of these transcripts may encode novel proteins the function of the majority is yet to be determined. The authors have used strand-specific deep sequencing of RNA, irrespective of poly(A) status, to reveal a highly structured antisense programme that modulates gene expression to dictate cell fate decisions during sexual differentiation. They show that an extensive and elaborate array of ncRNA production accompanies sexual differentiation in the fission yeast S. pombe. Experimental manipulation suggests that these transcripts specifically regulate the function of the target genes.

Comparative organization of cattle chromosome 5 revealed by comparative mapping by annotation and sequence similarity and radiation hybrid mapping

A whole genome cattle-hamster radiation hybrid cell panel was used to construct a map of 54 markers located on bovine chromosome 5 (BTA5). Of the 54 markers, 34 are microsatellites selected from the cattle linkage map and 20 are genes. Among the 20 mapped genes, 10 are new assignments that were made by using the comparative mapping by annotation and sequence similarity strategy. A LOD-3 radiation hybrid framework map consisting of 21 markers was constructed. The relatively low retention frequency of markers on this chromosome (19%) prevented unambiguous ordering of the other 33 markers. The length of the map is 398.7 cR, corresponding to a ratio of ≈2.8 cR5,000/cM. Type I genes were binned for comparison of gene order among cattle, humans, and mice. Multiple internal rearrangements within conserved syntenic groups were apparent upon comparison of gene order on BTA5 and HSA12 and HSA22. A similarly high number of rearrangements were observed between BTA5 and MMU6, MMU10, and MMU15. The detailed comparative map of BTA5 should facilitate identification of genes affecting economically important traits that have been mapped to this chromosome and should contribute to our understanding of mammalian chromosome evolution.

General and specific brain regions involved in encoding and retrieval of events: what, where, and when.

Remembering an event involves not only what happened, but also where and when it occurred. We measured regional cerebral blood flow by positron emission tomography during initial encoding and subsequent retrieval of item, location, and time information. Multivariate image analysis showed that left frontal brain regions were always activated during encoding, and right superior frontal regions were always activated at retrieval. Pairwise image subtraction analyses revealed information-specific activations at (i) encoding, item information in left hippocampal, location information in right parietal, and time information in left fusiform regions; and (ii) retrieval, item in right inferior frontal and temporal, location in left frontal, and time in anterior cingulate cortices. These results point to the existence of general encoding and retrieval networks of episodic memory whose operations are augmented by unique brain areas recruited for processing specific aspects of remembered events.

Memory for object features versus memory for object location: a positron-emission tomography study of encoding and retrieval processes.

Regional cerebral blood flow was measured with positron-emission tomography during two encoding and two retrieval tasks that were designed to compare memory for object features with memory for object locations. Bilateral increases in regional cerebral blood flow were observed in both anterior and posterior regions of inferior temporal cortex and in ventral regions of prestriate cortex, when the condition that required retrieval of object locations was subtracted from the condition that required retrieval of object features. During encoding, these changes were less pronounced and were restricted to the left inferior temporal cortex and right ventral prestriate cortex. In contrast, both encoding and retrieval of object location were associated with bilateral changes in dorsal prestriate and posterior parietal cortex. Finally, the two encoding conditions activated left frontal lobe regions preferentially, whereas the two retrieval conditions activated right frontal lobe regions. These findings confirm that, in human subjects, memory for object features is mediated by a distributed system that includes ventral prestriate cortex and both anterior and posterior regions of the inferior temporal gyrus. In contrast, memory for the locations of objects appears to be mediated by an anatomically distinct system that includes more dorsal regions of prestriate cortex and posterior regions of the parietal lobe.

The Tube on YouTube: TV Series, Media Strategies, and User Tactics in a Transmedia Environment

This study analyzes the traffic generated on YouTube around television series. We selected a sample of 314 short YouTube videos about 21 Spanish TV series that premiered in 2013 by Spain’s three most popular mainstream television networks (Telecinco, Antena 3, and La1). These videos, which together received more than 24 million views, were classified according to two key variables: the nature (official or nonofficial) of the YouTube channel on which they were located and the exclusivity of their content (already broadcast on TV or Web exclusive). The analysis allows us to characterize the strategies used by TV networks on YouTube and the activity of fans as well as their efforts in the construction of a transmedia narrative universe around TV series.

Lost in Translation? Russian Media Portrayals and Laypersons’ Interpretations of Angelina Jolie’s Breast Cancer Discourse

In May 2013, Angelina Jolie revealed that because she had a family history of breast and ovarian cancer and carried a rare BRCA gene mutation, she had undergone a preventive double mastectomy. Media coverage has been extensive around the world, including in Russia, not an English-language country, where all global news is inevitably filtered by translation. After examining the reactions of Russian mass media and members of the public to Jolie’s disclosure, I consider what transformations have occurred with Jolie’s message in the process of cross-cultural transfer. I explore the mass media portrayal of Jolie’s announcement, laypersons’ immediate and prolonged reactions, and the reflections of patients involved directly in the field of hereditary breast cancer. To my knowledge, this multifaceted and bilingual project is the first conceptualization of Jolie’s story as it has been translated in a different sociocultural environment. I start with examination of offline and online publications that appeared in Russia within two months after Jolie’s announcement. In this part of my analysis, I conceptualize the representation of Jolie’s case in Russian mass media and grasp what sociocultural waves were generated by this case among general lay audiences. Another part of my study contains the results of qualitative in-depth interviews. Eight women with a family history of hereditary breast cancer were recruited to participate in the research. The findings represent Jolie’s case through the eyes of Russian women with the same gene mutation as Jolie. Consolidating my findings, I argue that Jolie’s announcement was misinterpreted and misrepresented by Russian mass media, as well as misunderstood by a considerable part of the media audience. Jolie’s perspective on hereditary breast cancer mostly remained unheard among members of the Russian public. I make suggestions about the reasons for such a phenomenon, and demonstrate how Jolie’s case is implicated in politics, economics, and the culture of contemporary Russia.

Mutual perceptions of Asia and the EU/Europe. Media, elite and public opinion in Singapore and Germany. EU Centre in Singapore Working Paper No. 12, December 2012

In an increasingly interlinked and interdependent world, Europe and Asia are key players. Free trade agreements (FTAs), such as the ones the EU concluded with South Korea and Singapore, are indicative of strong mutual economic interests. It is therefore timely to take a closer look at the mutual perceptions of Asians and Europeans – not only at the governmental and policymaking levels, but also in terms of public opinion and the media. Drawing on data from an extensive research project led by the National Centre for Research on Europe (NCRE), New Zealand, the empirical study in this paper assesses the mutual perceptions of the EU/Europe and Asia, and their respective actors, focusing on two countries – Germany and Singapore. It seeks to do so through an analysis of the data collected from print and broadcast media, interviews with media practitioners, and the findings from public opinion surveys.

The media, marketing, and single sex schooling

The Australian media's interest in education, as in many Anglophone countries, is frequently dominated by concerns about boys in schools. In 2002, in a country region of the Australian State of Queensland, this concern was evident in a debate on the merits of single sex schooling that took place in a small local newspaper. The debate was fuelled by the inclusion in this newspaper of an advertising brochure for an elite private girls' school. The advertisement utilized the current concerns about boys in schools to advocate the benefits of girls' only schools. Drawing on research that suggests that boys are a problem in school, and utilising a peculiar mix of liberal feminism alongside a neo-liberal class politics, it implicitly denigrated the education provided by government co-educational schools. The local government high and primary school principals, incensed at this advertisement, contacted the paper to refute many of its claims and assumptions and to assert the benefits, to both boys and girls, of their particular schools. A letters to the editor debate then followed an article representing these government school principals' views. These letters were from two private school principals. This country newspaper thus became a medium through which various school principals engaged with the current boys' debate, and research associated with it, in order to market their schools. This paper examines this particular newspaper debate and argues that, in the absence of nuanced, research based, and thoughtful policy responses to gender issues, many school policies on gender are being shaped through and by the media in ways that elide the complexities of the issues involved.
