    This concise, thorough, and beautifully produced volume is one of the very few studies of a small site of the ancient Maya civilization of the Classic period (AD 300-900). It fills a major gap in the study of Classic Maya sites and is a volume that every Maya archaeologist should read. Maya archaeology, in general, has not been as theoretically and methodologically sophisticated as other subfields of archaeology and anthropology. Perhaps it is because of this traditionalist approach that exca..

    Reporting on electoral violence in Nigerian news media: “Saying it as it is”?

    Get PDF
    While Nigeria has a vibrant press media landscape, freedom of the press is only rated as “partly free” by Freedom House, mostly due to political influences on reporting. Yet the extent to which these influences affect the quality of reporting remains insufficiently investigated. We address this gap by analyzing how three newspapers with different political affiliations report on conflict in the run-up to the 2015 elections. Our analyses indicate that biases in reporting are generally limited, and that while political pressures are real, they are most evident in editorial choices.The Institutions of Politics; Design, Workings, and implications ( do not use, ended 1-1-2020

    How events enter (or not) data sets: the pitfalls and guidelines of using newspapers in the study of conflict

    While conflict event data sets are increasingly used in contemporary conflict research, important concerns persist regarding the quality of the collected data. Such concerns are not necessarily new. Yet, because the methodological debate and evidence on potential errors remains scattered across different subdisciplines of social sciences, there is little consensus concerning proper reporting practices in codebooks, how best to deal with the different types of errors, and which types of errors should be prioritised. In this article, we introduce a new analytical framework—that is, the Total Event Error (TEE) framework—which aims to elucidate the methodological challenges and errors that may affect whether and how events are entered into conflict event data sets, drawing on different fields of study. Potential errors are diverse and may range from errors arising from the rationale of the media source (e.g., selection of certain types of events into the news) to errors occurring during the data collection process or the analysis phase. Based on the TEE framework, we propose a set of strategies to mitigate errors associated with the construction and use of conflict event data sets. We also identify a number of important avenues for future research concerning the methodology of creating conflict event data sets.Institutions, Decisions and Collective Behaviou

    Persistence of virus-specific immune responses in the central nervous system of mice after West Nile virus infection

    <p>Abstract</p> <p>Background</p> <p>West Nile virus (WNV) persists in humans and several animal models. We previously demonstrated that WNV persists in the central nervous system (CNS) of mice for up to 6 months post-inoculation. We hypothesized that the CNS immune response is ineffective in clearing the virus.</p> <p>Results</p> <p>Immunocompetent, adult mice were inoculated subcutaneously with WNV, and the CNS immune response was examined at 1, 2, 4, 8, 12 and 16 weeks post-inoculation (wpi). Characterization of lymphocyte phenotypes in the CNS revealed elevation of CD19<sup>+ </sup>B cells for 4 wpi, CD138 plasma cells at 12 wpi, and CD4<sup>+ </sup>and CD8<sup>+ </sup>T cells for at least 12 wpi. T cells recruited to the brain were activated, and regulatory T cells (Tregs) were present for at least 12 wpi. WNV-specific antibody secreting cells were detected in the brain from 2 to 16 wpi, and virus-specific CD8<sup>+ </sup>T cells directed against an immunodominant WNV epitope were detected in the brain from 1 to 16 wpi. Furthermore, these WNV-specific immune responses occurred in mice with and without acute clinical disease.</p> <p>Conclusions</p> <p>Virus-specific immune cells persist in the CNS of mice after WNV infection for up to 16 wpi.</p

    PHIL photoinjector test line

    LAL is now equiped with its own platform for photoinjectors tests and Research and Developement, named PHIL (PHotoInjectors at LAL). This facility has two main purposes: push the limits of the photoinjectors performances working on both the design and the associated technology and provide a low energy (MeV) short pulses (ps) electron beam for the interested users. Another very important goal of this machine will be to provide an opportunity to form accelerator physics students, working in a high technology environment. To achieve this goal a test line was realised equipped with an RF source, magnets and beam diagnostics. In this article we will desrcibe the PHIL beamline and its characteristics together with the description of the first two photoinjector realised in LAL and tested: the ALPHAX and the PHIN RF Guns
