    Breaking the Vainshtein screening in clusters of galaxies

    In this work we will test an alternative model of gravity belonging to the large family of galileon models. It is characterized by an intrinsic breaking of the Vainshtein mechanism inside large astrophysical objects, thus having possibly detectable observational signatures. We will compare theoretical predictions from this model with the observed total mass profile for a sample of clusters of galaxies. The profiles are derived using two complementary tools: X-ray hot intra-cluster gas dynamics, and strong and weak gravitational lensing. We find that a dependence with the dynamical internal status of each cluster is possible; for those clusters which are very close to be relaxed, and thus less perturbed by possible astrophysical local processes, the galileon model gives a quite good fit to both X-ray and lensing observations. Both masses and concentrations for the dark matter halos are consistent with earlier results found in numerical simulations and in the literature, and no compelling statistical evidence for a deviation from general relativity is detectable from the present observational state. Actually, the characteristic galileon parameter Υ\Upsilon is always consistent with zero, and only an upper limit (0.086\lesssim0.086 at 1σ1\sigma, 0.16\lesssim0.16 at 2σ2\sigma, and 0.23\lesssim0.23 at 3σ3\sigma) can be established. Some interesting distinctive deviations might be operative, but the statistical validity of the results is far from strong, and better data would be needed in order to either confirm or reject a potential tension with general relativity.Comment: 26 pages, 3 tables, 4 figures.

    Service-Learning for Preservice Teachers: Ethical Dilemmas for Practice

    Get PDF
    Increasingly in the United States, service-learning is being used to educate preservice teachers. Service varies greatly in its ethical foundation, however, and service-learning presents new teachers with a variety of dilemmas revealing the moral and political nature of teaching and service. This article presents one case of four preservice teachers writing curriculum as a service to a community agency hoping to promote service geared toward social justice among high school students. The case highlights ethical dilemmas faced by teachers in the process and illustrates the potential of service-learning to educate teachers for the moral imperative of their profession

    Exploring notions of genre in 'academic literacies' and 'writing across the curriculum': approaches across countries and contexts

    Get PDF
    The SIGET IV panel on genre in Writing Across the Curriculum (WAC) and “academic literacies” (ACLITS) has set rolling a discussion of the similarities and differences in the two traditions, the former originating in the US in the early 1970s, the latter originating in England in the early 1990s. This paper maps out some elements of each in relation to the other and to genre, which we hope will set in motion further discussions and cross-fertilization

    Pancreatic cancer patient survival correlates with DNA methylation of pancreas development genes.

    Get PDF
    DNA methylation is an epigenetic mark associated with regulation of transcription and genome structure. These markers have been investigated in a variety of cancer settings for their utility in differentiating normal tissue from tumor tissue. Here, we examine the direct correlation between DNA methylation and patient survival. We find that changes in the DNA methylation of key pancreatic developmental genes are strongly associated with patient survival
