Average flow constraints and stabilizability in uncertain production-distribution systems
2009
We consider a multi-inventory system with controlled flows and uncertain demands (disturbances) bounded within assigned compact sets. The system is modelled as a first-order one integrating the discrepancy between controlled flows and demands at different sites/nodes. Thus, the buffer levels at the nodes represent the system state. Given a long-term average demand, we are interested in a control strategy that satisfies just one of two requirements: (i) meeting any possible demand at each time (worst case stability) or (ii) achieving a predefined flow in the average (average flow constraints). Necessary and sufficient conditions for the achievement of both goals have been proposed by the aut…
Parenting Stress in Mothers of Children With Autism Without Intellectual Disability. Mediation of Behavioral Problems and Coping Strategies
2019
The present study investigated the mediating role of behavioral difficulties, coping strategies, and social functional support in the relationship between symptoms severity and parenting stress in mothers of children with ASD (autism spectrum disorder). The parenting stress questionnaire, coping orientation to problems experienced scale, strengths and difficulties questionnaire, and Duke-UNC social support questionnaire were administered to 52 mothers, who also estimated the ASD severity symptoms of their children. Correlation analyses revealed that parenting stress was positively correlated with the children's ASD symptoms and behavioral problems. On the other hand, parenting stress was ne…
Morphological analysis of phytoplankton as a tool to assess ecological state of aquatic ecosystems: the case of Lake Arancio, Sicily, Italy
2013
Phytoplankton requires a sufficient supply of light and nutrients to grow. At the same time it is largely entrained in water motion and is subject to grazing from planktonic herbivores. The pelagic life of lake phytoplankton is based on 4 pillars: living in suspension, light harvesting, nutrient uptake, and escape from grazing. Environmental variability and the uneven distribution of resources among and within the different aquatic ecosystems exert a selective pressure on these organisms, which are formed by a single cell or by colonies with either relatively low or high numbers of cells. Phytoplankton displays an amazing morphological variability representing an adaptation to spatial and t…
Herramientas para la mejora de las organizaciones educativas y su relación con el entorno.
2021
Mejorar la vinculación de las organizaciones educativas con el entorno supone un aspecto sumamente importante para el desarrollo socioeducativo de las comunidades en las que éstas se insertan. De hecho, impulsar y potenciar la relación entre las organizaciones educativas y el entorno es, en cierto modo, un ejercicio de responsabilidad que debe concretarse a través de actuaciones y herramientas favorecedoras del desarrollo de organizaciones capaces de aprender y promover la participación activa del entorno para conseguir sus metas. Esta aportación aborda propuestas como el trabajo en red, los planes educativos de entorno, la colaboración entre escuelas, municipio y familias, la planificación…
Estudio exploratorio de las estrategias de encuadre discursivo en memes humorísticos publicados en Twitter durante las elecciones generales de noviem…
2020
La presente investigación se basa en el análisis de un corpus de 115 memes humorísticos difundidos en la red social Twitter, durante las elecciones generales celebradas en España en noviembre de 2019. Para su recopilación se han consultado los tuits publicados haciendo uso de los hashtags que se convirtieron en trending topic, en el transcurso de la campaña electoral que tuvo lugar entre el 1 y el 10 de noviembre de 2019. En ellos hemos podido identificar los principales rasgos que caracterizan al discurso pseudopolítico y determinadas estrategias de encuadre discursivo utilizadas para movilizar el voto y orientar cognitivamente los mensajes. This research is based on the analysis of a corp…
The economic crisis in an industrial district and its effects on the migration flows
2013
El modelo económico de la provincia de Castellón, basado en la industria cerámica (más del 90% de la producción española) y la construcción, junto con las actividades relacionadas con el turismo, la agricultura intensiva de regadío y el servicio doméstico, generó una oferta de empleo impresionante que, entre 2000 y 2007, atrajo a miles de inmigrantes, la mayoría procedentes de Rumania. La actual crisis económica ha tenido efectos devastadores en esta provincia, donde la destrucción de puestos de trabajo ha sido mucho más intensa que en el conjunto estatal, al tiempo que el paro registra niveles más altos, sobre todo entre la población extranjera. El objetivo de este trabajo es analizar el i…
Pluriannual morphological variability in a highly productive Mediterranean reservoir (Lake Arancio, southwestern Sicily)
2007
The progressive decrease in water quality experienced by the Mediterranean, nutrient rich reservoir, Lake Arancio (Southwestern Sicily, Italy), has been accompanied by modifications in both phytoplankton shape and size. Since nutrient concentrations are always far from being limiting, in the present paper attention was focussed on the effects exerted by physical constraints (e.g., mixing, light availability) on the morphological variation observed in phytoplankton. The surface-volume ratio and its product with the maximal linear dimension were chosen as morphological descriptors to trace the trajectories followed by the dominant morphotypes in Lake Arancio. One of these descriptors was comp…
Motivazione. Strategie e metodologie innovative per vincere la noia a scuola.
2016
Molti alunni subiscono passivamente la scuola e gli successi, molti non riescono a trovare la motivazione per scegliere di studiare e di andare a scuola. Nelle concrete situazioni dell avita scolastica, le emozioni, gli effetti, i sentimenti e le passioni indicano significativamente nel processo di apprendimento; pertanto la comprensione delle dinamiche affettivi nei propri alunni costituisce una dimensione molto importante della professionalità docente. Many pupils passively undergo school and successes, many can not find the motivation to choose to study and go to school. In the concrete situations of school life, emotions, effects, feelings and passions indicate significantly in the lear…
Molecular Mechanisms of Inflammasome in Ischemic Stroke Pathogenesis.
2022
Ischemic stroke (also called cerebral ischemia) is one of the leading causes of death and severe disability worldwide. NLR inflammasomes play a crucial role in sensing cell damage in response to a harmful stimuli and modulating the inflammatory response, promoting the release of pro-inflammatory cytokines such as IL-18 and IL-1β following ischemic injury. Therefore, a neuroprotective effect is achieved by inhibiting the expression, assembly, and secretion of inflammasomes, thus limiting the extent of brain detriment and neurological sequelae. This review aims to illustrate the molecular characteristics, expression levels, and assembly of NLRP3 (nucleotide-binding oligomerization domain-like…
THE ROLE OF NATIONAL AUDIOVISUAL COUNCIL FROM ROMANIA AND THE IMPACT ON ELABORATING COMMUNICATION STRATEGIES
2015
In the present research I will analyze the reactions and opinions of the interviewed persons regarding the role of National Audiovisual Council from Romania, and also it will be analyzed the impact on elaborating communication strategiesy. At the same time, it is aimed at presenting some comparisons between: the general activity of the National Audiovisual Council and the displaying of main objectives, as well as the expectations of the public opinion about the work of this institution. Thereby, I will use the interview as a qualitative research method, to confirm or infirm the hypothesis of the present research.
