A generic tool to assess impact of changing edit rules in a business survey - an application to the UK Annual Business Inquiry part 2

Business surveys often use complex sets of edit rules (edits, for short) to check returned questionnaires (records), locate suspicious or unacceptable responses, and support data cleaning operations prior to using the survey responses for estimation of the required target parameters. These sets of edits are complex because they may involve large numbers of survey questionnaires and variables, they may contain a large number of edits, and the edits may depend on a large number of tolerance parameters. When such sets of edits are used, they may cause large numbers of record failures and generate substantial costs of revision, especially if edit failures are dealt with by means of clerical operations, like reviewing original paper questionnaires or digital images of these, and re-contacting businesses for clarification and/or correction of the responses provided. Costs can be high both in terms of the resources required, as well as in terms of timeliness of survey processing, by delaying availability of the survey data for estimation and publication.In this paper we describe a generic tool, developed as a result of the collaboration between the University of Southampton and the ONS. This tool can help to assess the potential impact of changing the edits in a specified business survey. It is a SAS macro using the IML language which enables calculation of a number of edit performance and data quality indicators. Changes to the set of edits aiming to ‘relax’ the existing edits so that failure rates decrease and efficiency savings are achieved are assessed by means of several edit-related performance indicators, like failure and hit rates, false hit rates, etc.. Data quality indicators include proportion of errors missed and estimates of the bias resulting from missing errors for a specified revision of the set of edits. Edit designers and managers can then aim to fine tune their edits so that failure rates, false hit rates and editing costs are reduced, while data quality is preserved. An illustration is provided by the application of the tool to revise the edits used for the UK Annual Business Inquiry Part 2 to the reference year 2007

Using the jet stream for sustainable airship and balloon transportation of cargo and hydrogen

© 2019 The Author(s) The maritime shipping sector is a major contributor to CO2 emissions and this figure is expected to rise in coming decades. With the intent of reducing emissions from this sector, this research proposes the utilization of the jet stream to transport a combination of cargo and hydrogen, using airships or balloons at altitudes of 10–20 km. The jet streams flow in the mid-latitudes predominantly in a west–east direction, reaching an average wind speed of 165 km/h. Using this combination of high wind speeds and reliable direction, hydrogen-filled airships or balloons could carry hydrogen with a lower fuel requirement and shorter travel time compared to conventional shipping. Jet streams at different altitudes in the atmosphere were used to identify the most appropriate circular routes for global airship travel. Round-the-world trips would take 16 days in the Northern Hemisphere and 14 in the Southern Hemisphere. Hydrogen transport via the jet stream, due to its lower energy consumption and shorter cargo delivery time, access to cities far from the coast, could be a competitive alternative to maritime shipping and liquefied hydrogen tankers in the development of a sustainable future hydrogen economy

Application of EPR Spectroscopy in TiO2 and Nb2O5 Photocatalysis

The interaction of light with semiconducting materials becomes the center of a wide range of technologies, such as photocatalysis. This technology has recently attracted increasing attention due to its prospective uses in green energy and environmental remediation. The characterization of the electronic structure of the semiconductors is essential to a deep understanding of the photocatalytic process since they influence and govern the photocatalytic activity by the formation of reactive radical species. Electron paramagnetic resonance (EPR) spectroscopy is a unique analytical tool that can be employed to monitor the photoinduced phenomena occurring in the solid and liquid phases and provides precise insights into the dynamic and reactivity of the photocatalyst under different experimental conditions. This review focus on the application of EPR in the observation of paramagnetic centers formed upon irradiation of titanium dioxide and niobium oxide photocatalysts. TiO2 and Nb2O5 are very well-known semiconductors that have been widely used for photocatalytic applications. A large number of experimental results on both materials offer a reliable platform to illustrate the contribution of the EPR studies on heterogeneous photocatalysis, particularly in monitoring the photogenerated charge carriers, trap states, and surface charge transfer steps. A detailed overview of EPR-spin trapping techniques in mechanistic studies to follow the nature of the photogenerated species in suspension during the photocatalytic process is presented. The role of the electron donors or the electron acceptors and their effect on the photocatalytic process in the solid or the liquid phase are highlighted

Host Plant Record for the Fruit Flies, Anastrepha fumipennis and A. nascimentoi (Diptera, Tephritidae)

The first host plant record for Anastrepha fumipennis Lima (Diptera: Tephritidae) in Geissospermum laeve (Vell.) Baill (Apocynaceae) and for A. nascimentoi Zucchi found in Cathedra bahiensis Sleumer (Olacaceae) was determined in a host plant survey of fruit flies undertaken at the “Reserva Natural da Companhia Vale do Rio Doce”. This reserve is located in an Atlantic Rain Forest remnant area, in Linhares county, state of Espírito Santo, Brazil. The phylogenetic relationships of Anastrepha species and their hosts are discussed. The occurrence of these fruit fly species in relation to the distribution range of their host plants is also discussed

El uso de las tecnologías digitales por bebés: de lecturas en el campo educativo

This production is added in the educational scene and in the field of articulations between psychoanalysis and education. It shows brief reflections on the digital technologies use for babies and their effects on social linking, based on the teaching experience of the first author in a public school in the Federal District - Brazil, which motivated her doctoral studies. We believe that the continuous training of teachers to guide the social relationships of the child, his parents and families, regarding the technology can be for emergency, when we are dealing with infants and children in their early childhood.La presente producción se inserta en el escenario educativo y en el campo de las articulaciones entre psicoanálisis y educación. Muestra breves reflexiones sobre el uso de las tecnologías digitales por bebés y sus efectos en el enlazamiento social, a partir de la experiencia docente de la primera autora en una escuela pública en el Distrito Federal - Brasil, que motivó sus estudios de doctorado. Pensamos que la formación continuada de profesores para orientar las relaciones sociales del niño, sus pares y familias, frente a la tecnología puede ser de emergencia, cuando estamos tratando de bebés y niños en su más tierna infancia
