    SVOD Global Expansion in Cross-National Comparative Perspective: Netflix in Israel and Spain

    Get PDF
    This article compares the processes by which Netflix entered national pay-television markets in Israel and Spain. In both contexts, Netflix first establishes itself through collaborations with over-the-top (OTT) television operators and then expands through collaborations with legacy providers. By using the perspective of cross-national comparative research, this analysis complicates the scholarly understandings of subscription video on-demand (SVOD) global expansion by drawing attention to the significance of national multichannel providers. Given the differences between the Spanish and Israeli pay-TV markets, Netflix’s similar pattern of engagement in each case highlights the value of understanding SVOD global expansion as a coherent industrial process that produces distinct, context-dependent outcomes. Ultimately, the histories of Netflix in Israel and Spain reveal that internationalization operates at a meso-level where collaborations with pay-television providers facilitate access to national audiences

    Global streaming platforms and national pay-television markets

    This research offers a “helicopter view” of the Israeli pay-television market eighteen months after Netflix’s global expansion to complicate the narrative of intractable conflict between subscription video on-demand (SVOD) platforms like Netflix and national television industries. Using data from qualitative interviews with ten industry executives, this article argues that relationships between global SVODs and local television providers are more varied than is widely believed. Israeli multi-channel executives consider Netflix to be an indirect competitor, view Netflix the content distributor as distinct from Netflix the content buyer, and expect Netflix to have little impact on the national market. Ultimately, these industry responses reaffirm the fundamental local-ness of television even as digital technology reshapes the relations between national and global industries

    Photons, neutrinos and optical activity

    We compute the one-loop helicity amplitudes for low-energy νγνγ\nu\gamma\to\nu\gamma scattering and its crossed channels in the standard model with massless neutrinos. In the center of mass, with s=2ω2me\sqrt{s} = 2\omega\ll 2m_e, the cross sections for these 222\to 2 channels grow roughly as ω6\omega^6. The scattered photons in the elastic channel are circularly polarized and the net value of the polarization is non-zero. We also present a discussion of the optical activity of a sea of neutrinos and estimate the values of its index of refraction and rotary power.Comment: 9 pages, ReVTeX4, 6 figures include

    Fluorescent carbon dioxide indicators

    Over the last decade, fluorescence has become the dominant tool in biotechnology and medical imaging. These exciting advances have been underpinned by the advances in time-resolved techniques and instrumentation, probe design, chemical / biochemical sensing, coupled with our furthered knowledge in biology. Complementary volumes 9 and 10, Advanced Concepts of Fluorescence Sensing: Small Molecule Sensing and Advanced Concepts of Fluorescence Sensing: Macromolecular Sensing, aim to summarize the current state of the art in fluorescent sensing. For this reason, Drs. Geddes and Lakowicz have invited chapters, encompassing a broad range of fluorescence sensing techniques. Some chapters deal with small molecule sensors, such as for anions, cations, and CO2, while others summarize recent advances in protein-based and macromolecular sensors. The Editors have, however, not included DNA or RNA based sensing in this volume, as this were reviewed in Volume 7 and is to be the subject of a more detailed volume in the near future

    Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

    Full text link
    We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.

    Outcome of children with multiply relapsed B-cell acute lymphoblastic leukemia: a therapeutic advances in childhood leukemia & lymphoma study.

    The survival of pediatric patients with multiply relapsed and/or refractory (R/R) B-cell acute lymphoblastic leukemia has historically been very poor; however, data are limited in the current era. We conducted a retrospective study to determine the outcome of multiply R/R childhood B-ALL treated at 24 TACL institutions between 2005 and 2013. Patient information, treatment, and response were collected. Prognostic factors influencing the complete remission (CR) rate and event-free survival (EFS) were analyzed. The analytic set included 578 salvage treatment attempts among 325 patients. CR rates (mean ± SE) were 51 ± 4% for patients with bone marrow R/R B-ALL who underwent a second salvage attempt, 37 ± 6% for a third attempt, and 31 ± 6% for the fourth through eighth attempts combined. For patients achieving a CR after their second, third, and fourth through eighth attempts, the 2 year EFS was 41 ± 6%, 13 ± 7%, and 27 ± 13% respectively. Our results showed slight improvement when compared to previous studies. This is the largest and most recent study to date that evaluates the outcome of this patient population. Our data will provide detailed reference for the evaluation of new agents being developed for childhood B-ALL

    Search for electroweak production of single top quarks in ppˉp\bar{p} collisions.

    We present a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use ~90 pb^-1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with the DZero detector between 1992 and 1995. We use events that include a tagging muon, implying the presence of a b jet, to set an upper limit at the 95% confidence level on the cross section for the s-channel process ppbar->tb+X of 39 pb. The upper limit for the t-channel process ppbar->tqb+X is 58 pb. (arXiv

    Search for the associated production of the Higgs boson with a top-quark pair

    Get PDF
    A search for the standard model Higgs boson produced in association with a top-quark pair t t ¯ H (tt¯H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb −1 and 19.7 fb −1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H → hadrons, H → photons, and H → leptons. The results are characterized by an observed t t ¯ H tt¯H signal strength relative to the standard model cross section, μ = σ/σ SM ,under the assumption that the Higgs boson decays as expected in the standard model. The best fit value is μ = 2.8 ± 1.0 for a Higgs boson mass of 125.6 GeV
