ETC/ATNI Report 2019/12: The impact of vehicle taxations system on vehicle emissions
No full textThe scope of this study is to find the real-world savings achieved in total CO2, NOx and PM10 emissions from the adoption of national policies and European legislation for the period 2010- 2017 for the new registered fleet based on appropriate scenarios developed for this study. In addition, a forecast of the relevant benefits until 2020 was also made.OCP/EEA/ACC/18/001-ETC/ATN
ETC/ATNI Report 2019/1: Noise indicators under the Environmental Noise Directive. Methodology for estimating missing data.
No full textMethodological report summarizing the steps followed to obtain estimated results of a complete noise exposure covering the END sources.
The process followed is described in different sections, from the input data being used until the final gap filling exercise to obtain the exposure numbers at EEA (39) level, if data available.
The method differs depending on the noise souce being gap filled, detailed in the different sections of the summary.
Results of the exercise are posted in ETC/ATNI Forum and will be used in different publications foreseen in 2019 by the EEA.
This report summarizes the methodology followed to gap fill the missing noise exposure data for 2012 and 2017 reference dataset.
Specific procedures have been implemented depending on the noise source expected to be gap filled, which are detailed in the different chapters of this document, distinguishing between major roads, major railways, major airports and the different sources inside agglomerations (road, rail, aircraft and industrial noise exposure).
The data being use for this exercise is data delivered by Member States in the corresponding Reportnet envelopes until 01/01/2019, for dataflows DF1_5 (and DF1) and DF4_8 (DF4) and considering the different reporting cycles.
Results have been posted in ETC/ATNI Forum and will be used in the different publications being issued during 2019 by the EEA.OCP/EEA/ACC/18/001-ETC/ATN
ETC/ATNI Report 2021/17: Wheat yield loss in 2019 in Europe due to ozone exposure.
No full textTropospheric ozone impacts agricultural crop and timber production, with significant economic effects for the sector. In the early 2000’s the PODy (phytotoxic ozone dose above a threshold y) indicator for calculating this impact was proposed by the expert group IPC-Vegetation working in support of the Air Convention. Within the ETC/ATNI, annual production of PODy maps has started in 2020. In this report we have implemented an impact modelling chain to quantify and monetize the loss in wheat production due to tropospheric ozone exposure for 2019. We also studied the sensitivity of the results to the degree of spatialization of the input data.
This study quantifies and monetizes losses of bread wheat production due to tropospheric ozone pollution in 2019 in Europe. It uses the POD6spec methodology and the flux-effect function recommended by the Mapping Manual of the Air Convention. Wheat production data from Eurostat are used together with international wheat prices calculated by dividing the Gross production value of wheat in 2019 by the production quantities, both from FAOSTAT.
The study calculates losses in wheat production for a reference case that started from wheat production data at regional level (NUTS 2), geolocated the production at grid level using Corine Landcover, and then calculated impacts at a grid level, before aggregating them at country level. Two sensitivity cases were also studied with degraded geolocation, one of which calculated impacts directly at country level.
It was shown that 2019 was a specific year, with low levels of PODy, possibly due to specific meteorological conditions during the accumulation period. Despite this, the reference case shows wheat production losses that reach levels between 8 % and 9 % in five countries and exceed 5 % for seventeen countries. Economic losses amount to several millions of € in the majority of countries.
When comparing these results to the two sensitivity cases, on a country level, percentage losses differed up to 2.8 percent. Aggregated at a European level, the differences were less than expected, but this is possibly related the low PODy levels in 2019.OCP/EEA/ACC/18/001-ETC/ATN
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
