Del acceso a la fragmentación del bienestar: Los servicios sociales de atención y desarrollo local en España
2018
Los Servicios Sociales son instrumentos al servicio de la política social para alcanzar objetivos de bienestar, calidad de vida y prosperidad de la población a que atienden. El presente documento muestra un breve repaso a la aparición de los Servicios Sociales en España, su génesis, evolución y la situación actual. Es objetivo del presente trabajo, mostrar la distinta implementación de los Servicios Sociales en el territorio español, dependiendo de la voluntad político-legislativa. Finalmente se destaca el preponderante papel de las rentas para la inserción de los usuarios de servicios sociales, la importancia de dimensionar la universalidad de los mismos como principio instaurador y la s…
On the positive aspects of customers: Customer-initiated support and affective crossover in employee-customer dyads
2011
This study examines psychological resources for service employees and their customers, which enhance the service experiences of both parties during service conversations. We investigate whether customer behaviour (customer-initiated support) positively impacts on employees' affect. We also examine the crossover of employees' affect on customers' affect. State positive affect (PA) was assessed in 82 employees of car dealerships and 421 customers on 2 occasions (before and after the conversation). Multi-level analyses showed the hypothesized positive impact of customer behaviour on employees' PA and in turn of employees' PA on customers' PA. Results are integrated in an overall process model …
Model-based approaches for the development of event-based systems using embedded services
2010
This paper presents a development use case of event-based system using (embedded) services specified in UPnP specification. Although we use only UPnP, we considered that the use case is also applicable for other (XML-based) service description technologies.

Trust enhancement of P2PSIP communication systems
2011
Today, peer-to-peer (P2P) session initiation protocol (SIP)-based communication systems have attracted much attention from both academia and industry. The decentralised nature of P2P might provide the distributed P2P communication system without help of the traditional SIP server. However, it comes to the cost of reduced trustworthiness and may cause security problems, e.g., privacy leaks, unpredictable availability, etc. In this paper, we investigate P2PSIP security issues and propose a subjective logic-based trust model that offers trust-based security services during P2PSIP session establishment. The main issues considered in this model include opinion calculation, opinion maintenance, d…
MATHEMATICS AS A QUASI-EMPIRICAL SCIENCE
2006
The present paper aims at showing that there are times when set theoretical knowledge increases in a non-cumulative way. In other words, what we call ‘set theory’ is not one theory which grows by simple addition of a theorem after the other, but a finite sequence of theories T1, ..., T n in which Ti+1, for 1 ≤ i < n, supersedes T i . This thesis has a great philosophical significance because it implies that there is a sense in which mathematical theories, like the theories belonging to the empirical sciences, are fallible and that, consequently, mathematical knowledge has a quasi-empirical nature. The way I have chosen to provide evidence in favour of the correctness of the main thesis of t…
ChemInform Abstract: Topologically Complex Molecules Obtained by Transition Metal Templation: It Is the Presentation that Determines the Synthesis St…
2013
Topological constructions made from closed curves range from simple links to intricate knots and started to capture the chemists' attention in the early sixties. These mathematical objects result from particular embeddings of a single or a set of closed curves in the three-dimensional space that show an infinite variety of presentations. Simple catenanes, higher order interlocked macrocycles, and molecular knots can be synthesized via the metal template approach, just as simple macrocycles. However, this requires that rigid presentations with appropriate geometrical characteristics be identified prior to molecular design, and those selected for the metal-templated synthesis of some of these…
UNA SOLUZIONE ANALITICA DELLA DISTRIBUZIONE DI PROBABILITÀ DELLA PORTATA DI PIENA PER VERSANTI PERMEABILI
2018
La conoscenza della risposta idrologica dei versanti è di fondamentale impor-tanza nel calcolo delle portate di piena, soprattutto per i piccoli bacini, in cui il comportamento del versante domina la risposta complessiva. È noto che la portata di piena, corrispondente alla durata critica della pioggia e, in particolare, la sua di-stribuzione di probabilità, sono necessarie in numerosi problemi pratici (il dimen-sionamento di opere idrauliche, la progettazione di infrastrutture urbane ed ex-traurbane, etc.). Nell’ipotesi che la formazione prevalente del deflusso superficiale avvenga secondo lo schema Hortoniano, tipico dei versanti con scarsa copertura ve-getale e modesta permeabilità dei su…
Una metodologia probabilistica semplificata di riproduzione del ruscellamento superficiale sul versante: possibili riscontri applicativi
2009
Il lavoro presenta un modello semplificato per la riproduzione del reticolo di ruscellamento superficiale sul versante. Il modello richiede solo due parametri, il primo è legato alla capacità di produzione del deflusso del versante, nella condizione iniziale del processo, il secondo dipende dal grado di divagazione del reticolo. Tali parametri, in chiave idrologica, danno conto degli effetti che principalmente influenzano la risposta idrologica del versante: l’intensità di pioggia, la macroscabrezza e la pendenza del versante stesso. L’attendibilità del modello richiede, ovviamente, una validazione sperimentale che al momento è stata solo avviata.
