CONTRIBUTO ALL’ADATTAMENTO ITALIANO DELLE SCALE SUL BENESSERE AFFETTIVO DI WARR
Introduzione Il benessere affettivo nei luoghi di lavoro è un tema a lungo trascurato a causa del susseguirsi di modelli teorici razionalistici di comprensione del rischio psicosociale. Il modello sviluppato da Warr (2007) si basa su un concetto di benessere psicologico definito in termini affettivi, ossia basato sulla tipologia di emo- zioni sperimentate dall’individuo. Nello specifico, l’autore ipo- tizza un modello multidimensionale di benessere che viene rappresentato da due dimensioni ortogonali (piacevolezza e attivazione mentale), ma misurato da tre dimensioni (piacevo- lezza, ansia-comfort, depressione-entusiasmo). Obiettivi e Metodi Scopo del presente contributo è valutare la strut…
An approach to the electrical tomography aimed to the investigation of particular confined structures
In this paper we present a practical approach to the electrical tomography when applied to materials having particular shapes (like the columns). Simple cylindrical shapes have been tested, and the general model has been selected as a set of elements having circular sections of some angle and thickness.
Propagation of errors due to incorrect positions of sources and detectors in wave-field tomography
Tomographic data processed by 2D inversion programs can produce fairly large distortions due to incorrect source and/or detector positions. This problem is very serious in high-frequency electromagnetic tomography (GPR), due to the dimensions of the transmitter and receiver antennae. The errors can even be larger when coupled antennae are used (receiver and transmitter inside the same box) whose positions are not clearly known. Similar errors can be involved in seismic tomography, for instance when the mechanical connection between transducers and sample is defective. In this paper the problem has been studied using synthetic data which were calculated for different acquisition geometries. …
