Secondary, security threat, and sage: Eulogy effect and the framing of female politicians as political martyrs in the Elite press of South Asia

How do newspapers frame female politicians, and does this framing change after a female politician\u27s death during an election campaign? Benazir Bhutto, who served two terms as prime minister of Pakistan, was assassinated in 2007 by a terrorist group. South Asian newspapers framed her as corrupt, inefficient, and a threat to national security before her death; however, the elite press characterized her as a martyr and sage posthumously. Using qualitative content analysis, this study examines the editorial coverage of two newspapers ( The Hindu and The Times of India) in India and two newspapers ( The News and The Dawn) in Pakistan to examine how these elite newspapers framed Benazir Bhutto before and after her tragic death. We found that the framing of the slain leader changed from negative to positive after her assassination. The study concludes that her assassination influenced the media coverage and produced a eulogy effect that helped her party stay in power after her assassination

Vertical and horizontal communication on the Facebook pages of 2014 Brazilian presidential candidates

Social networking sites can be defined as online services that allow users to create public or private profiles and, among other things, create connections, share opinions, news, and affections. In 2014, many electors in Brazil were engaged in the presidential campaign on these virtual spaces as never before. In this context, the research question guiding this study is: What are the communication strategies employed by electors and the three main presidential candidates in the online interaction processes during the 2014 Brazilian elections? To address this question, empirical research was employed using a qualitative approach to analyze comments posted in the candidates’ Facebook fan pages during that electoral process. Based on the research and theory in this field, two types of communication in the virtual space were investigated: (a) vertical communication through interaction between Internet users and campaign staff; and (b) horizontal communication among electors in the comments section. We conclude that, although the comments section of the candidates’ pages on Facebook is frequently used as a space both for mutual support and incivility against opponents, it is still used creatively for discussion on the candidates’ government plans, the situation of the country, attempts of engagement in the electoral process and exposure to ideologically crosscutting viewpoints

Factors affecting ammonium uptake in streams - an inter-biome perspective

The Lotic Intersite Nitrogen experiment (LINX) was a coordinated study of the relationships between North American biomes and factors governing ammonium uptake in streams. Our objective was to relate inter-biome variability of ammonium uptake to physical, chemical and biological processes. 2. Data were collected from 11 streams ranging from arctic to tropical and from desert to rainforest. Measurements at each site included physical, hydraulic and chemical characteristics, biological parameters, whole-stream metabolism and ammonium uptake. Ammonium uptake was measured by injection of \u275~-ammonium and downstream measurements of 15N-ammonium concentration. 3. We found no general, statistically significant relationships that explained the variability in ammonium uptake among sites. However, this approach does not account for the multiple mechanisms of ammonium uptake in streams. When we estimated biological demand for inorganic nitrogen based on our measurements of in-stream metabolism, we found good correspondence between calculated nitrogen demand and measured assimilative nitrogen uptake. 4. Nitrogen uptake varied little among sites, reflecting metabolic compensation in streams in a variety of distinctly different biomes (autotrophic production is high where allochthonous inputs are relatively low and vice versa). 5. Both autotrophic and heterotrophic metabolism require nitrogen and these biotic processes dominate inorganic nitrogen retention in streams. Factors that affect the relative balance of autotrophic and heterotrophic metabolism indirectly control inorganic nitrogen uptake

The Chandra Source Catalog

The Chandra Source Catalog (CSC) is a general purpose virtual X-ray astrophysics facility that provides access to a carefully selected set of generally useful quantities for individual X-ray sources, and is designed to satisfy the needs of a broad-based group of scientists, including those who may be less familiar with astronomical data analysis in the X-ray regime. The first release of the CSC includes information about 94,676 distinct X-ray sources detected in a subset of public ACIS imaging observations from roughly the first eight years of the Chandra mission. This release of the catalog includes point and compact sources with observed spatial extents <~ 30''. The catalog (1) provides access to the best estimates of the X-ray source properties for detected sources, with good scientific fidelity, and directly supports scientific analysis using the individual source data; (2) facilitates analysis of a wide range of statistical properties for classes of X-ray sources; and (3) provides efficient access to calibrated observational data and ancillary data products for individual X-ray sources, so that users can perform detailed further analysis using existing tools. The catalog includes real X-ray sources detected with flux estimates that are at least 3 times their estimated 1 sigma uncertainties in at least one energy band, while maintaining the number of spurious sources at a level of <~ 1 false source per field for a 100 ks observation. For each detected source, the CSC provides commonly tabulated quantities, including source position, extent, multi-band fluxes, hardness ratios, and variability statistics, derived from the observations in which the source is detected. In addition to these traditional catalog elements, for each X-ray source the CSC includes an extensive set of file-based data products that can be manipulated interactively.Comment: To appear in The Astrophysical Journal Supplement Series, 53 pages, 27 figure
