LR-NIMBUS : an interactive algorithm for uncertain multiobjective optimization with lightly robust efficient solutions
2022
In this paper, we develop an interactive algorithm to support a decision maker to find a most preferred lightly robust efficient solution when solving uncertain multiobjective optimization problems. It extends the interactive NIMBUS method. The main idea underlying the designed algorithm, called LR-NIMBUS, is to ask the decision maker for a most acceptable (typical) scenario, find an efficient solution for this scenario satisfying the decision maker, and then apply the derived efficient solution to generate a lightly robust efficient solution. The preferences of the decision maker are incorporated through classifying the objective functions. A lightly robust efficient solution is generated …
Multiobjective optimization and decision making in engineering sciences
2021
AbstractReal-world decision making problems in various fields including engineering sciences are becoming ever more challenging to address. The consideration of various competing criteria related to, for example, business, technical, workforce, safety and environmental aspects increases the complexity of decision making and leads to problems that feature multiple competing criteria. A key challenge in such problems is the identification of the most preferred trade-off solution(s) with respect to the competing criteria. Therefore, the effective combination of data, skills, and advanced engineering and management technologies is becoming a key asset to a company urging the need to rethink how…
The nationality of companies in French law
2012
The development of international economic relations and the construction of an integrated European area, both from an economic and a political point of view, has revived the debate on the nationality of trading companies. The question is not so much whether trading companies have a nationality on an equal footing with natural persons – solutions have long been accepted by international doctrine and jurisprudence – but rather to determine how this notion has evolved and adapted to the constraints on the one hand, of a globalized market economy and, on the other hand, of European Union law which overturns the traditionally accepted solutions of nationality of trading companies into the legal …
Propiedades psicométricas y estructura factorial del BRCS en una muestra de personas mayores españolas
2015
Successful resilience is a variable often related to an optimal ag-ing process. However, literature is rather limited when dealing with assess-ment instruments for the elderly in the Spanish language. The objective of this work is to validate the Brief Resilient Coping Scale (Sinclair & Wallston, 2004), a four item likert scale, in the Spanish elderly. For this propose, the scale was administrated to a sample of 991 elderly Spanish participants, and the data set analysed in terms of exploratory and confirm-atory factor analysis, internal consistency and criterion validity. The scale demonstrated good psychometric properties. Furthermore, the homogenei-ty indices were higher than the recentl…
Sintering of copper nanopowders under hydrogen: an in situ X-ray diffraction analysis.
2003
Abstract The reduction by hydrogen gas of the cuprite layer on copper nanocrystals and the subsequent sintering of the nano-particles were studied using in-situ X-ray diffraction and dilatometry. Spherical nanocrystals produced by evaporation and condensation have an average size of 35 nm, exhibiting a large surface curvature. Each nanoparticle is coated with a 3.5 nm layer of Cu 2 O, which is rough and disordered, as revealed by high-resolution electron microscopy. Reduction by hydrogen of this curved cuprite layer occurs at 363 K, which is ≈65 K lower than is observed on a layer supported by micrometer-sized or bulk copper with a flat surface. The reduction process and its effect on the s…
Successful crisis communication in the public sector : communication experts' views on best practices and quality
2011
Crisis communication measurements have been adopted in many Finnish public sector organizations in past few years, but there has been a little research about how effective the plans and the measurements made are. Focus of this research is to define public sector communication experts’ views on best practices behind crisis communication and clarify how they evaluate quality in crisis communication in the public sector. The aim of the study is also to see the comparison between the theory and the views that the public sector experts have. The study is part of the international research “Developing a Crisis Communication Scorecard, coordinated by the Communication department of University of J…
Capacidad de indagación científica del profesorado de primaria en formación: efectos del género y de la formación previa
2022
El objetivo principal de este trabajo fue determinar el nivel de competencia en indagación científica del profesorado de primaria en formación inicial. Otros objetivos fueron analizar la influencia del género y de los estudios previos al acceso a la Universidad de este profesorado sobre los diversos elementos de la indagación científica, y evaluar cuáles de estos elementos resultan de mayor dificultad. Para ello, se administró un cuestionario de indagación científica a 178 estudiantes españoles del Grado en Maestro/a en Educación Primaria. De las puntuaciones obtenidas en el cuestionario y de las pruebas estadísticas llevadas a cabo se puede concluir que: a) la capacidad de indagación cient…
Relaciones en la educación secundaria entre creencias sobre ciencia y disposición hacia el pensamiento crítico, nivel académico y género
2022
El propósito de este estudio fue investigar la posible influencia de la disposición hacia el pensamiento crítico, el nivel de formación académica y el género (variables independientes) sobre el nivel de calidad de las creencias sobre ciencia de los estudiantes de secundaria (variable dependiente). Han participado 141 estudiantes españoles de secundaria, 75 chicos y 66 chicas, de 2º y 3º de Educación Secundaria Obligatoria -ESO- (8º y 9º grado), y de 1º de Bachillerato (11º grado). A todos ellos se les han administrado dos cuestionarios, uno de creencias sobre ciencia y uno de disposición hacia el pensamiento crítico. De la matriz de correlaciones producto-momento de Pearson entre variables …
Application of Cell Culture for the Production of Bioactive Compounds from Sponges: Synthesis of Avarol by Primmorphs from Dysidea avara
2000
Among all metazoan phyla, sponges are known to produce the largest number of bioactive compounds. However, until now, only one compound, arabinofuranosyladenine, has been approved for application in humans. One major obstacle is the limited availability of larger quantities of defined sponge starting material. Recently, we introduced the in vitro culture of primmorphs from Suberites domuncula, which contain proliferating cells. Now we have established the primmorph culture also from the marine sponge Dysidea avara and demonstrate that this special form of sponge cell aggregates produces avarol, a sesquiterpenoid hydroquinone, known to display strong cytostatic activity especially against ma…
Toll-like receptors are part of the innate immune defense system of sponges (demospongiae: Porifera).
2006
During evolution and with the emergence of multicellular animals, the need arose to ward off foreign organisms that threaten the integrity of the animal body. Among many different receptors that participate in the recognition of microbial invaders, toll-like receptors (TLRs) play an essential role in mediating the innate immune response. After binding distinct microbial components, TLRs activate intracellular signaling cascades that result in an induced expression of diverse antimicrobial molecules. Because sponges (phylum Porifera) are filter feeders, they are abundantly exposed to microorganisms that represent a potential threat. Here, we describe the identification, cloning, and deduced …
