El Cuestionario de Ansiedad Laboral (C.A.L.). Resultados preliminares
1993
La aceptación de la naturaleza multidimensional de la ansiedad ha llevado a su abandono como una entidad explicativa unitaria. Las dimensiones de la ansiedad comprenden las interacciones entre el ambiente y el comportamiento cognitivo y/o fisiológico y/o motor, y dado que los tres sistemas interactúan entre sí, es necesaria la medición de las tres dimensiones. Sin embargo, en muchas investigaciones solo se ha medido uno de los componentes de la ansiedad, como ocurre en el ámbito de las organizaciones, en el cual frecuentemente solo se ha intentado medir uno de los componentes de la ansiedad laboral: el componente cognitivo o tensión. Además, la medida de la ansiedad laboral no está tan desa…

Algunes aportacions de la psicologia social a la psicologia de la salut ocupacional
2010
L'objectiu d'aquest estudi és presentar una revisió sobre les característiques de la Psicologia de la salut ocupacional 'd'ara endavant, PSO' i algunes de les contribucions principals que la Psicologia social ha fet al seu desenvolupament, com a disciplina científica i cos de coneixements. L'estudi comença amb una presentació d'alguns dels canvis que han tingut lloc en les últimes dècades i que han afavorit l'aparició de la PSO. En el segon punt, s'hi aborda el concepte, els orígens i els objectius de la PSO. A continuació, s'hi revisen els mètodes d'investigació que han utilitzat els acadèmics i professionals de la PSO, i s'hi distingeix entre els mètodes d'investigació quantitatius i qual…
Cognitive processes of emotional regulation, burnout and work engagement
2019
Workers constantly resort to cognitive processes of emotion regulation to deal with emotions they experience in the workplace. These processes belong either to the 'automatic' (preconscious and fast) or the 'elaborative' (conscious and slow) mode. This study aims to determine the role of these variables in the work setting and to analyze their relationship with positive and negative affect, engagement and burnout. Method: 350 employees (54.8% men and 45.2% women) were presented with several instruments measuring burnout, engagement, affect and cognitive emotion regulation strategies in a prospective study. An explanatory model was tested through structural equation modeling analysis. Result…
ZERO: An Efficient Ethernet-Over-IP Tunneling Protocol
2013
An Ethernet over IPv4 tunneling protocol is proposed, which categorizes all Ethernet frames to be tunneled into NICE and UGLY frames. The UGLY frames are tunneled by traditional methods, such as UDP or GRE encapsulation, resulting in substantial overhead due to additional headers and fragmentation usually required to transport long Ethernet frames over IP network typically limited to MTU=1,500 bytes. Meanwhile the NICE Ethernet frames are tunneled without any overhead as plain IPv4 packets due to non-traditional reuse of “fragment offset” or “identification” field in the IP header. It is shown that for typical Internet traffic transported over Ethernet, the proposed ZERO tunneling protocol …
Preparation and characterization of dummy-template molecularly imprinted polymers as potential sorbents for the recognition of selected polybrominate…
2018
The main aim of this work was to conduct the preliminary/basic research concerning the preparation process of a new dummy molecularly imprinted polymer (DMIP) materials. Developed DMIPs were proposed as a sorption material in solid-phase extraction (SPE) technique for recognition of selected low mass polybrominated diphenyl ethers (PBDEs) – PBDE-47 and PBDE-99. Four new DMIPs were synthesized employing bulky polymerization technique by application of structural analogue of low mass PBDEs - 4,4′-Dihydroxydiphenyl ether, as a dummy template. The DMIPs and corresponding non-imprinted polymers were prepared using different functional monomers: methacrylic acid; methyl methacrylate and different…
L’etichettatura di sostenibilità nel settore vitivinicolo
2022
Nel settore vitivinicolo la sostenibilità e la sua comunicazione al consumatore per mezzo dell’etichettatura, nel rispetto della normativa in materia, ha assunto una crescente rilevanza, anche in ragione delle pressanti esigenze ambientali e climatiche che costringono ad un ripensamento in chiave digitale di sistemi e tecniche di produzione, in un’ottica di ottimizzazione e preservazione delle risorse naturali. Partendo da una preliminare riflessione circa il significato giuridico del termine “sostenibile”, il contributo si sofferma su come il legame tra iniziativa imprenditoriale, sviluppo di innovative tecnologie digitali, ricerca di nuovi spazi di mercato e sicurezza giuridica abbia anc…

EUROHERIT Policy Brief: Optimizing Communication, Multilingualism, and Networking in the EHL
2018
Efficient communication is important for the sustainability of cultural heritage schemes. Being a rather new action, the European Heritage Label (EHL) struggles with issues of visibility and wider recognition among European citizens, in part resulting from modest communication of the diverse actors within the action. To both increase the visibility of the EHL and promote efficient audience engagement, with an emphasis on multilingual representation of Europe’s diverse cultural heritage, we recommend concrete measures to improve coordinated communication among the EHL actors. Our recommendations consist of three thematic areas: communication, multilingualism, and networking.
Challenges for Creating Visibility of European Cultural Heritage : A Case Study of the European Heritage Label
2019
The European Heritage Label (EHL) is a recent flagship heritage action of the European Union and focuses on the European dimension of Europe’s history and heritage as part of the Union’s cultural policy. One of the central concerns of the EU’s cultural policy is to generate a sense of belonging and identity among European citizens. While efficient promotion of the visibility of the EHL among European audiences could be expected corresponding to the political objectives, the EHL continues to struggle with broader public recognition. Based on fieldwork findings, the article discusses the visibility of the EHL action as a network of heritage sites that challenges national narratives by promoti…
