Described are the results of a pilot application intended to automate the data collection and data reduction phases of roadside origin-destination (O-D) studies. Most techniques used to obtain O-D data are quite labor intensive, during both the data collection and the data reduction phase. Frequently, they result in extensive data quality checks and long turnaround periods between the data collection work and the submittal of the corresponding survey report. The application described automates the data collection and data reduction phases by using portable, handheld data collection devices. These devices can be connected to a desktop or laptop computer to transfer the O-D data to a depository database. Included are a brief background discussion, a description of the hardware and software used and the design and development of O-D applications, a description of two applications of the handheld data collection devices, and a list of lessons learned.

At least four major factors affect single-crystal diffraction data quality: 1) Hardware (source, goniometer and detector), 2) the sample, 3) the data collection procedure and strategy, and 4) the integration and data reduction software. Three of these factors can be carefully designed by the instrument manufacturer, and the other (the sample) can be chosen to optimize interaction with the instrument. We can define important hardware factors to allow quantification, such as absolute detectivity, overhead, readout speed, minimizing dead time and diffractometer access. Advances in area detector technology (including the new S2 generation of area detectors) and data collection approaches will be presented. The experimental procedure includes the choice of wavelength and the geometric strategy. Details of the detector operation (gain, bin-mode) can be optimized to fit the experiment. Agilent's latest CrysAlisPro software implements the 4th generation of strategy software and includes new on-the-fly detector optimization to provide significant gains in data quality. Integration software must be flexible in order to extract consistently good intensities from excellent samples and also from those that suffer from real-life flaws. Twinned samples represent an additional challenge. Agilent's new data reduction approach for twins significantly improves the data quality of both small molecule and protein twins.

ABSTRACT 2017-284: Over the past decade, three realizations have evolved from our collection and analysis of oil spill data. First is that more response data are being collected than ever before, including field and laboratory measurements in addition to observational data. To process this diverse information, we use sophisticated computer-based systems that allow us to integrate, analyze, and visualize satellite imagery, real-time weather and ship locations, field notes (e.g., shoreline cleanup assessment technique [SCAT] data), chemistry data, and photos. The second is the increased political and social interest in spills. Increased use of social media and the impact of these information pathways on the public’s perception of the spill response can drive real political decisions; making spill communications based on timely and high data quality critical. Lastly is the growing linkages between the collection, management, and uses of environmental data, not only for spill response, but also for NRD assessment (NRDA), determination of civil penalties (e.g., the Clean Water Act [CWA]), and third party legal claims. For example, observational and remote sensing data collected for response actions will ultimately be used to understand questions about contaminant pathways and exposures inherent to NRDA. Similarly, data collected as part of response mitigation and cleanup needs often provides our earliest understanding of the potential and actual natural resource damage issues, which are important for NRDA, third party claims, and CWA penalty mitigation. Historically, the inherent differences in temporal and spatial scales over which oil spill data are collected and used, coupled with the requirements of data quality, usability, and/or provenance, diminishes the ability to effectively optimize collection and uses of these data. Data optimization recognizes that data can/will have multiple uses and thus requires all data, whether response or NRDA-related to be of high and equivalent quality and be based on compatible, if not identical, data quality objectives (DQOs). In this paper, we review several examples that underscore the need for data optimization in environmental data collection. Specifically, we will explore how a focus on the long view and the need for data optimization can drive the collection of appropriate and multipurpose data, as well as inform the structure of data management systems. Using specific examples, we will demonstrate the value of embracing a data optimization framework in developing a common sample/data collection imperative that facilitates multiple uses.

Abstract Background Hemolytic uremic syndrome (HUS) is a rare condition which diagnosed with the triad of thrombocytopenia, microangiopathic hemolytic anemia, and acute renal injury. There is a high requirement for research to discover treatments. HUS registries can be used as an important information infrastructure. In this study, we identified and compared the different features of HUS registries to present a guide for the development and implementation of HUS registries. Results The purposes of registries were classified as clinical (9 registries), research (7 registries), and epidemiological (5 registries), and only 3 registries pursued all three types of purposes. The data set included demographic data, medical and family history, para-clinical and diagnostic measures, treatment and pharmacological data, complications, and outcomes. The assessment strategies of data quality included monthly evaluation and data audit, the participation of physicians to collect data, editing and correcting data errors, increasing the rate of data completion, following guidelines and data quality training, using specific data quality indicators, and real-time evaluation of data at the time of data entry. 8 registries include atypical HUS patients, and 7 registries include all patients regardless of age. Only two registries focused on children. 4 registries apply prospective and 4 applied both prospective, and retrospective data collection. Finally, specialized hospitals were the main data source for these registries. Conclusion Based on the findings, we suggested a learning framework for developing and implementing an HUS registry. This framework includes lessons learned and suggestions for HUS registry purposes, minimum data set, data quality assurance, data collection methods, inclusion and exclusion criteria as well as data sources. This framework can help researchers develop HUS registries.

The advent of the Portable Antiquities Scheme (PAS) has added a great deal to our understanding of prehistoric metal artefacts in England and Wales, namely in expanding enormously the corpuses of objects previously thought to be quite scarce. One such artefact type is the miniature socketed 'votive' axe, most of which are found in Wiltshire and Hampshire. As a direct result of developing such recording initiatives, reporting of these artefacts as detector finds from the early 2000s onwards has virtually trebled the number originally published by Paul Robinson in his 1995 analysis. Through extensive data-collection, synthesising examples recorded via the PAS with those from published excavations, the broad aims of this paper (in brief) are as follows: firstly, produce a solid typology for these artefacts; secondly, investigate their spatial distribution across England and Wales. As a more indirect third aim, this paper also seeks to redress the imbalance of focus and academic study specifically applying to Hampshire finds of this object type, which despite producing a significant proportion of the currently known corpus have never been the subject of detailed analysis.

ObjectiveTo present a costing study integrated within the DeWorm3 multi-country field trial of community-wide mass drug administration (cMDA) for elimination of soil-transmitted helminths.DesignTailored data collection instruments covering resource use, expenditure and operational details were developed for each site. These were populated alongside field activities by on-site staff. Data quality control and validation processes were established. Programmed routines were used to clean, standardise and analyse data to derive costs of cMDA and supportive activities.SettingField site and collaborating research institutions.Primary and secondary outcome measuresA strategy for costing interventions in parallel with field activities was discussed. Interim estimates of cMDA costs obtained with the strategy were presented for one of the trial sites.ResultsThe study demonstrated that it was both feasible and advantageous to collect data alongside field activities. Practical decisions on implementing the strategy and the trade-offs involved varied by site; trialists and local partners were key to tailoring data collection to the technical and operational realities in the field. The strategy capitalised on the established processes for routine financial reporting at sites, benefitted from high recall and gathered operational insight that facilitated interpretation of the estimates derived. The methodology produced granular costs that aligned with the literature and allowed exploration of relevant scenarios. In the first year of the trial, net of drugs, the incremental financial cost of extending deworming of school-aged children to the whole community in India site averaged US$1.14 (USD, 2018) per person per round. A hypothesised at-scale routine implementation scenario yielded a much lower estimate of US$0.11 per person treated per round.ConclusionsWe showed that costing interventions alongside field activities offers unique opportunities for collecting rich data to inform policy toward optimising health interventions and for facilitating transfer of economic evidence from the field to the programme.Trial registration numberNCT03014167; Pre-results.
