Organizing PMODE Dopplergrams of Jupiter with MATLAB

The interiors of the giant planets are poorly known. At the time of writing, such investigations have been limited to measuring gravitational effects from a handful of orbital probes. The most recent attempt to map the interior is via PMODE (the Planetary Multilevel Oscillations and Dynamics Experiment), designed to explore Jupiter’s core by collecting Dopplergrams. Small radial velocity shifts in Jupiter’s upper cloud decks enable us to map its atmospheric dynamics and consequently its interior via Dioseismology (techniques similar to Helioseismology, applied to Jupiter). This campaign produced a vast dataset with more than 50,000 exposures, every 30 seconds, over 24 nights. These unique data currently lack basic archival header information such as pointing locations, planetary latitude, instrumental statistics etc., which makes efficient analysis difficult. Our goal is to collect and insert required information automatically into each individual FITS file header and upload the entire database to NASA’s Planetary Data System for the general scientific community. The indexed catalog will open up a significant wealth of data for further study of Jupiter’s interior. We present the current state of the project, the ultimate end goals, and a plan for future analysis

Case Study of Assessment in a High School Classroom: The Impact of Changes in Assessment on Curriculum, Instruction, Teachers, and Students

This study examined the impact of changes in assessment on curriculum, instruction, teachers, and students. The study describes the complex, developmental process by which a particular course, teachers, and a class evolved, articulated goals and standards, and assessed their learning. My co-teacher and I used a variety of assessments: conferences, peer review, reflections, portfolios, group projects, and presentations in addition to traditional tests and quizzes. The methodology was a qualitative study by a teacher/researcher in a high school Humanities class

High temperature radiator materials for applications in the low Earth orbital environment

Radiators must be constructed of materials which have high emittance in order to efficiently radiate heat from high temperature space power systems. In addition, if these radiators are to be used for applications in the low Earth orbital environment, they must not be detrimentally affected by exposure to atomic oxygen. Four materials selected as candidate radiator materials (304 stainless steel, copper, titanium-6% aluminum-4% vanadium (Ti-6%Al-4%V), and niobium-1% zirconium (Nb-1%Zr)) were surface modified by acid etching, heat treating, abrading, sputter texturing, electrochemical etching, and combinations of the above in order to improve their emittance. Combination treatment techniques with heat treating as the second treatment provided about a factor of two improvement in emittance for 304 stainless steel, Ti-6%Al-4%V, and Nb-1%Zr. A factor of three improvement in emittance occurred for discharge chamber sputter textured copper. Exposure to atomic oxygen in an RF plasma asher did not significantly change the emittance of those samples that had been heat treated as part of their texturing process. An evaluation of oxygen penetration is needed to understand how oxidation affects the mechanical properties of these materials when heat treated

Lynx UK Trust consultation brief: Kielder

The University of Cumbria (UoC) has been asked to develop a community engagement programme for the Lynx UK Trust (Trust) as part of the Trust’s site selection process for the trial reintroduction of Eurasian lynx (lynx lynx) to the UK. Public consultation is a key element of any (trial) reintroduction proposal. The International Union for Conservation of Nature (IUCN) Reintroduction Guidelines and Directive 92/43/EEC Conservation of Natural Habitats, Wild Flora and Fauna (the Habitats Directive) Article 22 and The Scottish Code for Conservation Translocations (2014) state that reintroduction should only take place after proper consultation with the public concerned. Community support is fundamentally important to this project and it is essential that the local community is given the necessary information and support to enable them to make an informed decision regarding the desirability of the trial

Influenza Vaccine Effectiveness against Hospitalisation with Confirmed Influenza in the 2010-11 Seasons: A Test-negative Observational Study

Immunisation programs are designed to reduce serious morbidity and mortality from influenza, but most evidence supporting the effectiveness of this intervention has focused on disease in the community or in primary care settings. We aimed to examine the effectiveness of influenza vaccination against hospitalisation with confirmed influenza. We compared influenza vaccination status in patients hospitalised with PCR-confirmed influenza with patients hospitalised with influenza-negative respiratory infections in an Australian sentinel surveillance system. Vaccine effectiveness was estimated from the odds ratio of vaccination in cases and controls. We performed both simple multivariate regression and a stratified analysis based on propensity score of vaccination. Vaccination status was ascertained in 333 of 598 patients with confirmed influenza and 785 of 1384 test-negative patients. Overall estimated crude vaccine effectiveness was 57% (41%, 68%). After adjusting for age, chronic comorbidities and pregnancy status, the estimated vaccine effectiveness was 37% (95% CI: 12%, 55%). In an analysis accounting for a propensity score for vaccination, the estimated vaccine effectiveness was 48.3% (95% CI: 30.0, 61.8%). Influenza vaccination was moderately protective against hospitalisation with influenza in the 2010 and 2011 seasons

Community consultation report: Kielder

This report is based on consultation work completed on behalf of the Lynx UK Trust (LUKT) in and around the Kielder area from August 2016 to May 2017, and was requested by the LUKT to fit with their timeline for a licence submission to trial a reintroduction of Eurasian lynx (lynx lynx) to the UK. As the planned consultation activities are incomplete, this is presented as an interim report, and conclusions should be considered as tentative. Nevertheless, initial findings point towards a reasonably divided community, with most residents still undecided or unsure regarding the proposed reintroduction of lynx and a small minority either firmly supporting or opposing the project. This position is similar to the results of an independent national omnibus survey conducted as part of a national public survey in respect of the proposed trial lynx reintroduction (Smith et al., 2015). At this point in the local consultation process there has been insufficient communication with those groups likely to be most affected by the project: primarily from the farming and forestry sector (IUCN, 2013:11). This is one of the IUCN’s key social feasibility guidelines (Social Feasibility 5.3.3) and for key areas of project policy, for example around livestock predation compensation schemes and mitigation measures, we would expect to see genuine co-development of policy and protocols with the farming community. This work has started in Kielder but given the controversial nature of this project it will take considerable time and effort to establish a trusting relationship with some of the human communities in and around the Kielder area. As the IUCN (2013:11) indicates, understanding the ‘extreme and internally contradictory attitudes of such key stakeholders provides the basis for developing public relations…orienting the public in favour of a translocation.’ It is our view that any licence application at this stage would be premature and would threaten the longer-term viability of the project

Environmental Indicators for the Coastal Region of the U.S. Great Lakes

The goal of this research collaboration was to develop indicators that both estimate environmental condition and suggest plausible causes of ecosystem degradation in the coastal region of the U.S. Great Lakes. The collaboration consisted of 8 broad components, each of which generated different types of environmental responses and characteristics of the coastal region. These indicators included biotic communities of amphibians, birds, diatoms, fish, macroinvertebrates, and wetland plants as well as indicators of polycyclic aromatic hydrocarbon (PAH) photo-induced toxicity and landscape characterization. These components are summarized below and discussed in more detailed in 5 separate reports (Section II). Stress gradients within the U.S. Great Lakes coastal region were defined from 207 variables (e.g., agriculture, atmospheric deposition, land use/land cover, human populations, point source pollution, and shoreline modification) from 19 different data sources that were publicly available for the coastal region. Biotic communities along these gradients were sampled with a stratified, random design among representative ecosystems within the coastal zone. To achieve the sampling across this massive area, the coastal region was subdivided into 2 major ecological provinces and further subdivided into 762 segment sheds. Stress gradients were defined for the major categories of human-induced disturbance in the coastal region and an overall stress index was calculated which represented a combination of all the stress gradients. Investigators of this collaboration have had extensive interactions with the Great Lakes community. For instance, the Lake Erie Lakewide Area Management Plan (LAMP) has adopted many of the stressor measures as integral indicators of the condition of watersheds tributary to Lake Erie. Furthermore, the conceptual approach and applications for development of a generalized stressor gradient have been incorporated into a document defining the tiered aquatic life criteria for defining biological integrity of the nation’s waters. A total of 14 indicators of the U.S. Great Lakes coastal region are presented for potential application. Each indicator is summarized with respect to its use, methodology, spatial context, and diagnosis capability. In general, the results indicate that stress related to agricultural activity and human population density/development had the largest impacts on the biotic community indicators. In contrast, the photoinduced PAH indicator was primarily related to industrial activity in the U.S. Great Lakes, and over half of the sites sampled were potentially at risk of PAH toxicity to larval fish. One of the indicators developed for land use/land change was developed from Landsat imagery for the entire U.S. Great Lakes basin and for the period from 1992 to 2001. This indicator quantified the extensive conversions of both agricultural and forest land to residential area that has occurred during a short 9 year period. Considerable variation in the responses were manifest at different spatial scales and many at surprisingly large scales. Significant advances were made with respect to development of methods for identifying and testing environmental indicators. In addition, many indicators and concepts developed from this project are being incorporated into management plans and U.S. 8 EPA methods documents. Further details, downloadable documents, and updates on these indicators can be found at the GLEI website - http://glei.nrri.umn.edu
