Geographically intelligent disclosure control for flexible aggregation of census data

This paper describes a geographically intelligent approach to disclosure control for protecting flexibly aggregated census data. Increased analytical power has stimulated user demand for more detailed information for smaller geographical areas and customized boundaries. Consequently it is vital that improved methods of statistical disclosure control are developed to protect against the increased disclosure risk. Traditionally methods of statistical disclosure control have been aspatial in nature. Here we present a geographically intelligent approach that takes into account the spatial distribution of risk. We describe empirical work illustrating how the flexibility of this new method, called local density swapping, is an improved alternative to random record swapping in terms of risk-utility

On transport integration: a contribution to better understanding

Over the years there have been many forecasts of transport futures. Most have taken a technological perspective, but this paper differs. Our perspective, linked to current transport policy debates, concerns the processes, institutions and structures within which transport technologies develop. ‘Integration’ is taken as our focus, because the concept of ‘integrated transport’ has become an important guiding principle for transport policies' institutional and structural development in several countries. Much has been talked about the need to reduce significantly the environmental impact of transport. While technical solutions that reduce the impact of individual journeys have a place, it is unlikely that they alone can reduce the impact of transport to a sustainable level. Only the development of highly integrated strategies have the potential to improve sustainability. Such strategies involve areas of activity that are not traditionally considered part of the transport planning process, such as health, urban regeneration, and education. There is no widely accepted definition of what Integrated Transport means. It is to help clarify such ambiguities that this paper has been written. This paper explores the meaning of Integrated Transport and considers whether such strategies will contribute to sustainability. Using examples from photography and computer system design the paper shows that there is a need to develop a better understanding of the meaning of Integrated Transport, outlining a typology developed to classify various definitions of Integrated Transport. Integrated Transport is viewed as scalar in nature, with higher levels incorporating lower, or narrower, understandings of the term Integrated Transport. Points on this scale include: • Functional or Modal Integration, which is part of... • Transport and Planning Integration, which is part of... • Social Integration, which is part of... • Environmental, Economic and Transport Policy Integration Transport Integration may be considered as a series of steps, with an incremental approach leading to higher levels of both Integration and Sustainability. Only by commitment, and allocation of resources, to the highest levels, will issues of sustainability be properly addressed

Perceptions and Experiences of Drug Use Among Women in Rural North Carolina

This study describes perceptions and experiences of drug use among 32 women residing in three non-urban counties in eastern North Carolina. Participants described drug use in their families and communities as pervasive, citing both individual (e.g., depression) and systemic (e.g., few opportunity structures) causal factors. Participants with personal drug use histories described factors that helped them reduce drug use as well as the challenges of maintaining recovery in small communities. Contributions of this research include rural women’s assessment and attribution of drug use problems in both their personal lives and larger communities. Recommendations for rural drug treatment providers are offered

Here Today, Gone within a Month: The Fleeting Life of Digital News

In 1989 on the shores of Montana’s beautiful Flathead Lake, the owners of the weekly newspaper the Bigfork Eagle started TownNews.com to help community newspapers with developing technology. TownNews.com has since evolved into an integrated digital publishing and content management system used by more than 1600 newspaper, broadcast, magazine, and web-native publications in North America. TownNews.com is now headquartered on the banks of the mighty Mississippi river in Moline Illinois. Not long ago Marc Wilson, CEO of TownNews.com, noticed that of the 220,000+ e-edition pages posted on behalf of its customers at the beginning of the month, 210,000 were deleted by month’s end. What? The front page story about a local business being sold to an international corporation that I read online September 1 will be gone by September 30? As well as the story about my daughter’s 1st place finish in the district field and track meet? A 2014 national survey by the Reynolds Journalism Institute (RJI) of 70 digital-only and 406 hybrid (digital and print) newspapers conclusively showed that newspaper publishers also do not maintain archives of the content they produce. RJI found a dismal 12% of the “hybrid” newspapers reported even backing up their digital news content and fully 20% of the “digital-only” newspapers reported that they are backing up none of their content. Educopia Institute’s 2012 and 2015 surveys with newspapers and libraries concur, and further demonstrate that the longstanding partner to the newspaper—the library—likewise is neither collecting nor preserving this digital content. This leaves us with a bitter irony, that today, one can find stories published prior to 1922 in the Library of Congress’s Chronicling America and other digitized, out-of-copyright newspaper collections but cannot, and never will be able to, read a story published online less than a month ago. In this paper we look at how much news is published online that is never published in print or on more permanent media. We estimate how much online news is or will soon be forever lost because no one preserves it: not publishers, not libraries, not content management systems, and not the Internet Archive. We delve into some of the reasons why this content is not yet preserved, and we examine the persistent challenges of digital preservation and of digital curation of this content type. We then suggest a pathway forward, via some initial steps that journalists, producers, legislators, libraries, distributors, and readers may each take to begin to rectify this historical loss going forward

GREENHOUSE GAS FLUXES IN AGRICULTURAL SOILS UNDER ORGANIC AND NON-ORGANIC MANAGEMENT

Farming practices are known to exert strong control over the soils’ function to act as sources or sinks for greenhouse gases (GHG). This paper deals with the outcome of a recent meta-analysis based on the evaluation of 19 published long-term farming system comparisons. It provides a comprehensive data base regarding GHG fluxes from soils under organic and non-organic management. There is scientific evidence for lower nitrous oxide emissions from organically managed soils when scaled to the area. However, further data from farming system comparisons are required, particularly from long-term GHG measurements covering several cropping seasons or ideally entire crop rotations. This enables closing knowledge gaps concerning N fluxes and pools under organic management as well as the formation of the new soil ecosystem (soil quality) equilibrium after implementing organic practices. Substantial reductions of nitrous oxide emissions as well as enhancement of methane uptake can be reached by consequent application of “good agricultural practice” and simple adoptions of soil management, forming together a balanced set of GHG mitigation mechanisms. In addition we provide first GHG flux data from the well-known DOK farming system trial in Therwil/CH and the role of microbial communities driving soil functioning

A novel counterbalanced implementation study design : methodological description and application to implementation research

Background: Implementation research is increasingly being recognised for optimising the outcomes of clinical practice. Frequently, the benefits of new evidence are not implemented due to the difficulties applying traditional research methodologies to implementation settings. Randomised controlled trials are not always practical for the implementation phase of knowledge transfer, as differences between individual and organisational readiness for change combined with small sample sizes can lead to imbalances in factors that impede or facilitate change between intervention and control groups. Within-cluster repeated measure designs could control for variance between intervention and control groups by allowing the same clusters to receive a sequence of conditions. Although in implementation settings, they can contaminate the intervention and control groups after the initial exposure to interventions. We propose the novel application of counterbalanced design to implementation research where repeated measures are employed through crossover, but contamination is averted by counterbalancing different health contexts in which to test the implementation strategy. Methods: In a counterbalanced implementation study, the implementation strategy (independent variable) has two or more levels evaluated across an equivalent number of health contexts (e.g. community-acquired pneumonia and nutrition for critically ill patients) using the same outcome (dependent variable). This design limits each cluster to one distinct strategy related to one specific context, and therefore does not overburden any cluster to more than one focussed implementation strategy for a particular outcome, and provides a ready-made control comparison, holding fixed. The different levels of the independent variable can be delivered concurrently because each level uses a different health context within each cluster to avoid the effect of treatment contamination from exposure to the intervention or control condition. Results: An example application of the counterbalanced implementation design is presented in a hypothetical study to demonstrate the comparison of 'video-based' and 'written-based' evidence summary research implementation strategies for changing clinical practice in community-acquired pneumonia and nutrition in critically ill patient health contexts. Conclusion: A counterbalanced implementation study design provides a promising model for concurrently investigating the success of research implementation strategies across multiple health context areas such as community-acquired pneumonia and nutrition for critically ill patients. © 2019 The Author(s). **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Jennifer Martin" is provided in this record*

Application of Optimal Control to CPMG Refocusing Pulse Design

We apply optimal control theory (OCT) to the design of refocusing pulses suitable for the CPMG sequence that are robust over a wide range of B0 and B1 offsets. We also introduce a model, based on recent progress in the analysis of unitary dynamics in the field of quantum information processing (QIP), that describes the multiple refocusing dynamics of the CPMG sequence as a dephasing Pauli channel. This model provides a compact characterization of the consequences and severity of residual pulse errors. We illustrate the methods by considering a specific example of designing and analyzing broadband OCT refocusing pulses of length 10 t180 that are constrained by the maximum instantaneous pulse power. We show that with this refocusing pulse, the CPMG sequence can refocus over 98% of magnetization for resonance offsets up to 3.2 times the maximum RF amplitude, even in the presence of +/- 10% RF inhomogeneity.Comment: 23 pages, 10 figures; Revised and reformatted version with new title and significant changes to Introduction and Conclusions section
