A relativistic Glauber approach to polarization transfer in 4He(\vec{e},e'\vec{p})

Polarization-transfer components for 4He(\vec{e},e'\vec{p})3H are computed within the relativistic multiple-scattering Glauber approximation (RMSGA). The RMSGA framework adopts relativistic single-particle wave functions and electron-nucleon couplings. The predictions with free and various parametrizations for the medium-modified electromagnetic form factors are compared to the world data.Comment: 2 pages, 1 figure Proceedings of the Int.

Extracting the Weinberg angle at intermediate energies

A recent experiment by the NuTeV collaboration resulted in a surprisingly high value for the weak mixing angle $\sin^2 \theta_W$. The Paschos-Wolfenstein relation, relating neutrino cross sections to the Weinberg angle, is of pivotal importance in the NuTeV analysis. In this work, we investigate the sensitivity of the Paschos-Wolfenstein relation to nuclear structure aspects at neutrino energies in the few GeV range. Neutrino-nucleus cross sections are calculated for $^{16}$O and $^{56}$Fe target nuclei within a relativistic quasi-elastic nucleon-knockout model.Comment: To appear in the proceedings of International School of Nuclear Physics: 27th Course: "Neutrinos in Cosmology, in Astro, Particle and Nuclear Physics", Erice, Sicily, Italy, 16-24 Sep 200

\u3cem\u3eSalam Neighbor\u3c/em\u3e: Syrian Refugees Through the Camera Lens

This paper examines the documentary Salam Neighbor (2015), which celebrates the will of Syrian refugee women who are displaced in Jordan. The collective experience of the refugees portrayed in the documentary solicits a reaction from the Western viewer. To counteract the images of refugees in the media, documentaries can be a good alternative for mass media, which has been perpetuating a binary of the West and the Rest. The argument tackles the issue of this new representation of refugees in documentaries within a postcolonial paradigm of how we represent or speak to/with the Other in our technological age, as well as the possibilities of misrepresenting or silencing the Other through the camera lens

A Comparison of Induced Value and Home-Grown Value Experiments to Test for Hypothetical Bias in Contingent Valuation

This study tests the hypothesis that hypothetical bias may not be related to value elicitation; rather it may be a value formation problem. When participants are asked to indicate their willingness to pay for an induced value good, we find no evidence of hypothetical bias for three different commodity types (public good, private good, and publicly provided private good). However, when these same subjects are asked to value homegrown goods with no pre-assigned induced value using the same elicitation mechanism, hypothetical values are roughly double actual payments in all three cases. These results support the hypothesis that the process of forming values in a homegrown setting may be a key contributor to hypothetical bias.contingent valuation, hypothetical bias, experiments, induced values, home-grown values

EXAMINING THE ACTIVITIES, EFFECTIVENESS, AND CONTRIBUTION OF LOCAL HEALTH DEPARTMENTS USING A NATIONAL LONGITUDINAL SURVEY OF PUBLIC HEALTH SYSTEMS

Health services research and public health services and systems research in the past have contributed to a strong foundation of evidence-based progress in organizing, financing, and delivering medical care and public health strategies across the United States. The purpose of this dissertation was to examine disparities in public health systems and in the delivery of population health services in communities served by these systems using nationally representative data from the National Longitudinal Survey of Local Public Health Systems (1998, 2006, 2012, and 2014). Data from the 1998 cohort of 497 local health jurisdictions serving at least 100,000 residents, and from the 2014 expanded cohort of 546 local health jurisdictions serving less than 100,000 residents were used to conduct three studies. The first study “Local Public Health Systems and the burden of major heart diseases: A longitudinal analysis using National Longitudinal Survey of Local Public Health System” shows that stroke related mortality rate decreases over time in communities with increasing number of recommended population health activities. The second study “Rural Urban Differences in Recommended Population Health Activities and Organization of Public Health Delivery System Capital” shows that the urban communities with a centralized jurisdiction enjoy a greater availability of population health activities and a greater likelihood of being in a comprehensive population health system capital than rural non-centralized communities. The third study “Can comprehensive public health system determine the overall perceived effectiveness of public health activities and health status of a community?” shows a gradient relationship between public health systems composition and the ratings of perceived overall community health status and perceived effectiveness of the population health activities in communities where the most favorable ratings were observed in communities with comprehensive public health systems in comparison to conventional and limited public health systems

Inquiry into Co-Teaching in an Inclusive Classroom

A year-long inquiry was conducted in response to the following questions: How does the relationship and teaching practice of a new co-teaching partnership evolve throughout the course of a school year? How can a consultant support the work of a new co-teaching partnership? The work of a general education and special education teacher in their first year of co-teaching in a fourth grade inclusive classroom in an urban public school is described. Utilizing a collaborative consultation model, efforts to support the work of the co-teaching partnership were documented. Data collected and analyzed included: results of self-assessment surveys, audio-recordings of bi-weekly meetings, anecdotal impressions of meetings, and descriptive notes of classroom observations. This fourth grade team developed a productive co-teaching partnership. They forged a professional relationship while they honed their collaborative instructional practices. Resources that proved useful in this inquiry study as well as a broader review of the literature are included for teachers, mentors, and administrators interested in the work of co-teaching

Strangeness content of the nucleon in quasielastic neutrino-nucleus reactions

We present a systematic study of the sensitivity of quasielastic neutrino-nucleus cross sections at intermediate energies to the strange quark sea of the nucleon. To this end, we investigate the impact of the weak strangeness form factors on the ratio of proton-to-neutron knockout, the ratio of neutral-to-charged current cross sections, on the Paschos-Wolfenstein relation, and on the longitudinal helicity asymmetry. The influence of axial as well as vector strangeness effects is discussed. For the latter, we introduce strangeness parameters from various hadron models and from a recent fit to data from parity violating electron scattering. In our model, the nuclear target is described in terms of a relativistic mean-field approach. The effects of final-state interactions on the outgoing nucleon are quantified within a relativistic multiple-scattering Glauber approach. Our results are illustrated with cross sections for the scattering of 1 GeV neutrinos and antineutrinos off a $^{12}$C target. Folding with a proposed FINeSSE (anti)neutrino energy-distribution has no qualitative influence on the overall sensitivity of the cross-section ratios to strangeness mechanisms. We show that vector strangeness effects are large and strongly $Q^2$ dependent.Comment: 25 pages, 12 figures, submitted to Phys. Rev.

Impact of lens distrortions on strain measurements obtained with digital image correlation

The determination of strain fields based on displacements obtained via DIC at the micro-strain level is still a cumbersome task. In particular when high-strain gradients are involved, e.g. in composite materials with multidirectional fibre reinforcement, uncertainties in the experimental setup and errors in the derivation of the displacement fields can substantially hamper the strain identification process. In this contribution, the aim is to investigate the impact of lens distortions on strain measurements. To this purpose, we first perform pure rigid body motion experiments, revealing the importance of precise correction of lens distortions. Next, a uni-axial tensile test on a textile composite with spatially varying high strain gradients is performed, resulting in very accurate determined strains along the fibers of the materia
