Striking with social media: the contested (online) terrain of workplace conflict
In this paper we review the workplace battleground and explore the potential of social media for mobilizing social movements in labour conflicts and beyond. By conducting a case study with empirical accounts obtained from the 2010/2011 British Airways cabin crew dispute in the UK, along with secondary sources, we discern social media in the workplace as a contested field. Inquiring into the unfolding dynamic of social media and workplace conflict, we investigate the mobilizing prospects of theoretical concepts like ‘distributed
discourse’ and ‘accelerated pluralism’ through the analytical prism of our interviews (Bimber, 1998; Greene et al, 2003). Our analysis of these empirical accounts will tease out certain empowering potentials in the use of social media to shape discourse and mobilize movement. However, we also note that these same communicative actions may challenge internal union authority, generate counter-mobilizing efforts and constitute an integral part in exposing both our private and working lives to the processes of marketization and
commodification
Molecular, phenotypic, and sample-associated data to describe pluripotent stem cell lines and derivatives
The use of induced pluripotent stem cells (iPSC) derived from independent patients and sources holds considerable promise to improve the understanding of development and disease. However, optimized use of iPSC depends on our ability to develop methods to efficiently qualify cell lines and protocols, monitor genetic stability, and evaluate self-renewal and differentiation potential. To accomplish these goals, 57 stem cell lines from 10 laboratories were differentiated to 7 different states, resulting in 248 analyzed samples. Cell lines were differentiated and characterized at a central laboratory using standardized cell culture methodologies, protocols, and metadata descriptors. Stem cell and derived differentiated lines were characterized using RNA-seq, miRNA-seq, copy number arrays, DNA methylation arrays, flow cytometry, and molecular histology. All materials, including raw data, metadata, analysis and processing code, and methodological and provenance documentation are publicly available for re-use and interactive exploration at https://www.synapse.org/pcbc. The goal is to provide data that can improve our ability to robustly and reproducibly use human pluripotent stem cells to understand development and disease
Asymptotic Expansions for Stationary Distributions of Perturbed Semi-Markov Processes
New algorithms for computing of asymptotic expansions for stationary
distributions of nonlinearly perturbed semi-Markov processes are presented. The
algorithms are based on special techniques of sequential phase space reduction,
which can be applied to processes with asymptotically coupled and uncoupled
finite phase spaces.Comment: 83 page
Observation of Hadronic W Decays in t-tbar Events with the Collider Detector at Fermilab
We observe hadronic W decays in t-tbar -> W (-> l nu) + >= 4 jet events using
a 109 pb-1 data sample of p-pbar collisions at sqrt{s} = 1.8 TeV collected with
the Collider Detector at Fermilab (CDF). A peak in the dijet invariant mass
distribution is obtained that is consistent with W decay and inconsistent with
the background prediction by 3.3 standard deviations. From this peak we measure
the W mass to be 77.2 +- 4.6 (stat+syst) GeV/c^2. This result demonstrates the
presence of two W bosons in t-tbar candidates in the W (-> l nu) + >= 4 jet
channel.Comment: 20 pages, 4 figures, submitted to PR
Energy resolution and energy-light response of CsI(TI) scintillators for charged particle detection
This article describes the crystal selection and quality control utilized to
develop and calibrate a high resolution array of CsI(TI) scintillator crystals
for the detection of energetic charged particles. Alpha sources are used to
test the light output variation due to thallium doping gradients. Selection of
crystals with better than 1% non-uniformity in light output is accomplished
using this method. Tests with 240 MeV alpha beam reveal that local light output
variations within each of the tested CsI(TI) crystals limit the resolution to
about 0.5%. Charge and mass dependences in the energy - light output
relationship are determined by calibrating with energetic projectile
fragmentation beams.Comment: 24 pages, 7 figure
