Proximity as a Journalistic Keyword in the Digital Era : A study on the âclosenessâ of amateur news images
Proximity is an ambiguous journalistic notion for which there is no single definition. In this article, we re-evaluate the relevance and use of the concept in the digital news environment. Based on interviews with journalists in Finland and audience focus groups in Finland and the United Kingdom, we ask how new forms of visual amateur production incorporated into professional news journalism have transformed the concept. The concept of proximity has evolved from being a criterion of news selection into a central imperative of news production aiming to engage audiences. Through the prism of amateur news imagery, proximity appears as a spatio-temporal, emotional and strategic keyword.Peer reviewe
First-Year Spectroscopy for the SDSS-II Supernova Survey
This paper presents spectroscopy of supernovae discovered in the first season
of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for
and measures multi-band light curves of supernovae in the redshift range z =
0.05 - 0.4, complementing existing surveys at lower and higher redshifts. Our
goal is to better characterize the supernova population, with a particular
focus on SNe Ia, improving their utility as cosmological distance indicators
and as probes of dark energy. Our supernova spectroscopy program features
rapid-response observations using telescopes of a range of apertures, and
provides confirmation of the supernova and host-galaxy types as well as precise
redshifts. We describe here the target identification and prioritization, data
reduction, redshift measurement, and classification of 129 SNe Ia, 16
spectroscopically probable SNe Ia, 7 SNe Ib/c, and 11 SNe II from the first
season. We also describe our efforts to measure and remove the substantial host
galaxy contamination existing in the majority of our SN spectra.Comment: Accepted for publication in The Astronomical Journal(47pages, 9

Reclaiming heritage: colourization, culture wars and the politics of nostalgia
This article considers the discursive continuities between a specifically liberal defence of cultural patrimony, evident in the debate over film colourization, and the culture war critique associated with neo-conservatism. It examines how a rhetoric of nostalgia, linked to particular ideas of authenticity,canonicity and tradition,has been mobilized by the right and the left in attempts to stabilize the confguration and perceived transmission of American cultural identity. While different in scale, colourization and multiculturalism were seen to create respective (postmodern) barbarisms against which defenders of culture, heritage and good taste could unite. I argue that in its defence of the âclassicâ work of art, together with principles of aesthetic distinction and the value of cultural inheritance,the anti-colourization lobby helped enrich and legitimize a discourse of tradition that, at the end of the 1980s, was beginning to reverberate powerfully in the conservative challenge to a âcrisisâ within higher education and the humanities. This article attempts to complicate the contemporary politics of nostalgia, showing how a defence of cultural patrimony has distinguished major and minor culture wars, engaging left and right quite differently but with similar presuppositions

Comparative analysis of the transcriptome across distant species
The transcriptome is the readout of the genome. Identifying common features in it across distant species can reveal fundamental principles. To this end, the ENCODE and modENCODE consortia have generated large amounts of matched RNA-sequencing data for human, worm and fly. Uniform processing and comprehensive annotation of these data allow comparison across metazoan phyla, extending beyond earlier within-phylum transcriptome comparisons and revealing ancient, conserved features. Specifically, we discover co-expression modules shared across animals, many of which are enriched in developmental genes. Moreover, we use expression patterns to align the stages in worm and fly development and find a novel pairing between worm embryo and fly pupae, in addition to the embryo-to-embryo and larvae-to-larvae pairings. Furthermore, we find that the extent of non-canonical, non-coding transcription is similar in each organism, per base pair. Finally, we find in all three organisms that the gene-expression levels, both coding and non-coding, can be quantitatively predicted from chromatin features at the promoter using a 'universal model' based on a single set of organism-independent parameters
Did You Feel That? Developing Novel Multimodal Alarms for High Consequence Clinical Environments
Hospitals are overwhelmingly filled with sounds produced by
alarms and patient monitoring devices. Consequently, these
sounds create a fatiguing and stressful environment for both patients
and clinicians. As an attempt to attenuate the auditory sensory
overload, we propose the use of a multimodal alarm system in
operating rooms and intensive care units. Specifically, the system
would utilize multisensory integration of the haptic and auditory
channels. We hypothesize that combining these two channels in a
synchronized fashion, the auditory threshold of perception of participants
will be lowered, thus allowing for an overall reduction of
volume in hospitals. The results obtained from pilot testing support
this hypothesis. We conclude that further investigation of this
method can prove useful in reducing the sound exposure level in
hospitals as well as personalizing the perception and type of the
alarm for clinicians
