COMPARATIVE ASSESSMENT OF SEVERAL MULTI-CRITERIA DECISION ANALYSIS TOOLS FOR MANAGEMENT OF CONTAMINATED SEDIMENTS
2007
Over the past several decades, environmental decision-making strategies have evolved into increasingly more sophisticated, information-intensive, and complexapproaches including expert judgment, cost-benefit analysis, toxicological risk assessment, comparative risk assessment, and a number of methods forincorporating public and stakeholder values. This evolution has led to an improved array of decision-making aids, including the development of Multi-CriteriaDecision Analysis (MCDA) tools that offer a scientifically sound decision analytical framework. The existence of different MCDA methods and the availability of corresponding software contribute to the possibility of practical implementat…
Une nouvelle approche mixte d'enrichissement de dimensions dans un schéma multidimensionnel en constellation Application à la biodiversité des oiseaux
2015
International audience; Les entrepôts de données (DW) et les systèmes OLAP sont des technologies d'analyse en ligne pour de grands volumes de données, basés sur les be-soins des utilisateurs. Leur succès dépend essentiellement de la phase de conception où les exigences fonctionnelles sont confrontées aux sources de données (méthodologie de conception mixte). Cependant, les méthodes de conception existantes semblent parfois inefficaces, lorsque les décideurs définissent des exi-gences fonctionnelles qui ne peuvent être déduites à partir des sources de don-nées (approche centrée sur les données), ou lorsque le décideur n'a pas intégré tous ces besoins durant la phase de conception (approche c…
Dimension enrichment with factual data during the design of multidimensional models: application to bird biodiversity
2015
20 pages; International audience; Data warehouses (DW) and OLAP systems are technologies allowing the on-line analysis of huge volume of data according to decision-makers’ needs. Designing DW involves taking into account functional requirements and data sources (mixed design methodology) [1]. But, for complex applications, existing automatic design methodologies seem inefficient. In some cases, decision-makers need querying, as a dimension, data which have been defined as facts by actual automatic mixed approachs. Therefore, in this paper, we offer a new mixed refinement methodology relevant to constellation multidimensional schema. The proposed methodolgy allows to decision-makers to enric…
The Influence of Intangible Assets in the Company Performance: The Case of the World’s Most Profitable Corporations
2020
Intangible assets are no longer a competitive advantage, but a must if a company wants to create value for the long-term and maintain performance at a high level compared with its peers. Due to the various factors that contribute to the performance of a company, there are a plethora of methods to measure the impact of each one. This paper’s objective is to measure the performance of the company, with a focus on the contribution of the intangible assets. To fulfil this objective, financial ratios will be used, and a method (‘Calculated Intangible Value’) to quantify the impact of intangible assets. By applying a multiple discriminant analysis, two functions will result, a general one, and an…
Information in the aspect of security threats and challenges
2019
INFORMATION IN THE ASPECT OF SECURITY THREATS AND CHALLENGESIn the article, the author describes the driving force behind deliberate informational activities. He pays particular attention to the current security situation in the information dimension. Existing systems in the area of security management should be resistant to disinformation and informational operations. There is no room for the freedom of interpretation of the information acquired since every decision results in the actions of people, therefore it requires accuracy and caution. This issue takes on a special dimension when it concerns the state, because this environment contains specific features such as a changing environmen…
Clubes y selecciones nacionales de fútbol. La dimensión etnoterritorial del fútbol español
2006
The first part of this paper shows, from a general viewpoint, the historical simultaneity in the emergence and development of football and the building of modern Nation-States, as well as their next differentiation in the socio-economical context of globalization. This differentiation or institutional separation implies an alteration and readjustment of the identity dynamic associated to this sport. Above this historical and conceptual background we consider a research on the ethnoterritorial dimension of the Spanish football. After dedicating the second part of the article to study some ethnoterritorial keys of his historic development, in the third part we present the analysis of the Span…
The Dimension, Diversity and Complexity of the Macroeconomic Risk
2020
The approach at a macroeconomic level of the challenges in order to foster the competitiveness in certain economic areas implies understanding and assessing the risk as an essential element which can determine in every moment the availability of the mechanisms and the necessary resources for a sustainable future. Even if in a certain measure the risk has to be assumed, the losses caused by undesired events seem to be more ample than the benefits. The most important aspect and part of the risk management is represented by the fact that risk has to be distributed over time, its effects being extended for long periods. While the benefits are hard to distinguish, the efforts seem to be determin…
Development of a Reference Database for Beta-Delayed Neutron Emission
2021
Beta-delayed neutron emission is important for nuclear structure and astrophysics as well as for reactor applications. Significant advances in nuclear experimental techniques in the past two decades have led to a wealth of new measurements that remain to be incorporated in the databases. We report on a coordinated effort to compile and evaluate all the available beta-delayed neutron emission data. The different measurement techniques have been assessed and the data have been compared with semi-microscopic and microscopic-macroscopic models. The new microscopic database has been tested against aggregate total delayed neutron yields, time-dependent group parameters in 6-and 8-group re-present…
A comparison between industrial experts' and novices' haptic perceptual organization: a tool to identify descriptors of the handle of fabrics
2004
Abstract In descriptive analysis, the establishing of the list of attributes is crucial. Attributes should account for consumers' perceptions and be understood by professionals for efficient communication. This work was aimed at identifying the most appropriate attributes for fabric description from the terminology associated with both experts' and novices' haptic perceptual spaces. Eleven industrial experts and two groups of novices (20 males and 20 females) evaluated 26 clothing fabrics. They performed (1) a free-sorting task based on haptic similarities, (2) a description of the previously formed groups, and (3) a hedonic rating task for each fabric. The perceptual organization was simil…
Metadata-based Personalization in Data Warehouses
2015
Lielā datu noliktavās uzkrāto datu un atskaišu apjoma dēļ, atskaišu izpilde un pārlūkošana var būt nogurdinoša un laikietilpīga. Turklāt, lietotājs ir visai ierobežots savu vēlmju izteikšanā kvalitatīvāku rezultātu iegūšanai (arī komerciālos datu noliktavu atskaišu rīkos). Taču, ir jēga veikt eksperimentus personalizācijas iespēju jomā, kuru mērķis būtu lietotāja vajadzībām atbilstošu datu sniegšana, jo datu noliktavu personalizācijas pētījumi šobrīd ir attīstības stadijā. Pēc veiktā esošo datu noliktavu personalizācijas pieeju salīdzinājuma, pētījums tika attīstīts atskaišu rekomendāciju jomā, kurš balstās uz tiešā vai netiešā veidā iegūtiem lietotāja iestatījumiem par datu noliktavas shēm…
