[Appropriate cytotoxic drug usages in solid tumors: conformity to official labelling and level of scientific evidence]
2006
International audience; The definition of appropriate use of drugs is questioned in oncology. Daily therapeutic practices were compared to official labelling and to published scientific data in this retrospective study. It was carried out in two respective specialised centers, from January to September 2004. All chemotherapies administered for adult solid tumours and including one of the eleven studied drugs were evaluated. The analysis of use was performed by drug : conformity to the validated labelling and level of scientific evidence (at the period study). The study included 1,561 drug uses in 1,211 patients. The overall rate of conformity to official labelling was 81.7 % (67.1 % of stri…
The Conceptualisation and Measurement of Mega Sport Event Legacies
2007
This paper focuses on the legacy of mega sport events. First, the concept of legacy is defined before the problems of measuring and forecasting legacy are discussed. Benchmarking and the use of macro data do not correctly reveal legacy. Hence a bottom-up approach is introduced which identifies the event legacy by evaluation of ‘soft’ and ‘hard’ event-related changes in a host city. These changes are defined as ‘event-structures’ (infrastructure, knowledge, image, emotions, networks, culture). Many of them change the quality of location factors of the host city in the long-term. The benefits/costs through the transformation of the host city are the legacy of a mega sport event. Here a partic…
Boosting Design Space Explorations with Existing or Automatically Learned Knowledge
2012
During development, processor architectures can be tuned and configured by many different parameters. For benchmarking, automatic design space explorations (DSEs) with heuristic algorithms are a helpful approach to find the best settings for these parameters according to multiple objectives, e.g. performance, energy consumption, or real-time constraints. But if the setup is slightly changed and a new DSE has to be performed, it will start from scratch, resulting in very long evaluation times. To reduce the evaluation times we extend the NSGA-II algorithm in this article, such that automatic DSEs can be supported with a set of transformation rules defined in a highly readable format, the fuz…
Analysis of the Motor Vehicles Manufacturing Sector in Cataluña: Implementation with Radar Charts
2013
The representation of the average periods of maturation in the axes of a radial chart allows us to know the financial position reached by companies at the end of an economic year or in a certain period. The angular indicators obtained from the application of the cosine and sine theorems, according to plane geometry principles verify the deduction obtained from the observation of the radial chart and establish whether the result of each management areas displayed offers liquidez to the developed trading activity, or it is the financial positions regardless trading activity the ones which verifies the displayed financial position in the radial chart. The indicated ratio explains why companies…
Benchmarking Wilms’ tumor in multisequence MRI data: why does current clinical practice fail? Which popular segmentation algorithms perform well?
2019
Wilms' tumor is one of the most frequent malignant solid tumors in childhood. Accurate segmentation of tumor tissue is a key step during therapy and treatment planning. Since it is difficult to obtain a comprehensive set of tumor data of children, there is no benchmark so far allowing evaluation of the quality of human or computer-based segmentations. The contributions in our paper are threefold: (i) we present the first heterogeneous Wilms' tumor benchmark data set. It contains multisequence MRI data sets before and after chemotherapy, along with ground truth annotation, approximated based on the consensus of five human experts. (ii) We analyze human expert annotations and interrater varia…
Benchmarking open data efforts through indices and rankings: Assessing development and contexts of use
2022
Abstract This paper aims to provide a broad perspective on the development of benchmarking open data efforts through indices and rankings over the years, both at the level of countries and allowing for a cross-country comparison. The methodology follows a systematic search for the relevant resources, their classification and identification of six open data benchmarks to be further analyzed, the identification of their key components through decomposition, their description, and identifying the similarities and differences. Three major groups of indices and four periods that characterize the efforts to benchmark and measure the development of open data are identified, where the first measure…
Computational cluster validation for microarray data analysis: experimental assessment of Clest, Consensus Clustering, Figure of Merit, Gap Statistic…
2008
Abstract Background Inferring cluster structure in microarray datasets is a fundamental task for the so-called -omic sciences. It is also a fundamental question in Statistics, Data Analysis and Classification, in particular with regard to the prediction of the number of clusters in a dataset, usually established via internal validation measures. Despite the wealth of internal measures available in the literature, new ones have been recently proposed, some of them specifically for microarray data. Results We consider five such measures: Clest, Consensus (Consensus Clustering), FOM (Figure of Merit), Gap (Gap Statistics) and ME (Model Explorer), in addition to the classic WCSS (Within Cluster…
Determinants of diet and physical Activity (DEDIPAC): a summary of findings
2017
The establishment of the Determinants of Diet and Physical Activity (DEDIPAC) Knowledge Hub, 2013 – 2016, was the first action taken by the ‘ Healthy Diet for a Healthy Life ’ European Joint Programming Initiative. DEDIPAC aimed to provide better insight into the determinants of diet, physical activity and sedentary behaviour across the life course, i.e. insight into the causes of the causes of important, non-commu nicable diseases across Europe and beyond. DEDIPAC was launched in late 2013, and delivered its final report in late 2016. In this paper we give an overview of what was achieved in terms of furthering measurement and monitoring, providing overviews of the state-of-the-art in the …
Toward solutions for energy efficiency
2020
Abstract The tariff setting for district heating (DH) services is a hard regulatory procedure. This chapter is devoted to development of the simple but sufficiently accurate methodology for fast and objective evaluation of the actual costs of DH to optimize the regulatory process and to set adequate tariffs on heat production and transmission. The developed methodology is based on the data sets of Latvian DH providers, but the methodological principles are applicable in another area too. Investigation of heat production drivers and following simulation revealed the key performance indicators (KPIs): fuel type and price. By usage of intelligent benchmarking data mining methods and mathematic…
Benchmarking of outdoor activity facilities : an analysis of German hiking facilities and its implications to Finland
2015
The health effects of regular physical activity play an integral part in the promotion of outdoor participation. Well-maintained and marketed outdoor facilities encourage in this regard people to be more active outside of their homes. The aim of this study is to analyse popular German outdoor facilities in order to identify good working practices in Germany that can potentially be applied in Finland with the purpose of encouraging Finnish people to go outdoors more often. The study was conducted in cooperation between the University of Jyväskylä and Suomen Latu. The main research questions was: What knowledge can Suomen Latu gain from the administration of popular German hiking facilities i…
