This study aimed to obtain validity evidences of a teamwork performance scale. Team performance was understood as a mesolevel characteristic, resulting of an emerging process. Due to that understanding the proposed instrument should take that aspect into consideration. The empirical data were collected from 276 Ecuadorian teachers organized in 70 educational teams. They answered nine sentences of the scale. Results of exploratory factor analysis showed a unifactorial solution explaining 65.84% of the variance. The measure also has adequate values of reliability (Cronbach Alpha = .93). In addition to these analyses, patterns of variance within and between the groups were verified. The results showed that the variance at the individual level was small when answers of team members were analyzed and was significant when teams were compared. We consider it is important that additional studies be performed in order to identify stability of the factor solution. Key words: job performance; assessment scale; teamwork Desempenho de equipes: evidências de validade de uma medidaResumo O objetivo deste estudo foi desenvolver e verificar evidências de validade de uma medida que permita aferir o desempenho de equipes de trabalho. O desempenho foi entendido como atributo do nível meso, portanto, relativo às equipes, que surge mediante um processo de emersão e, desse modo, a medida deve considerar essa especificidade. Para a realização empírica da pesquisa contou-se com respostas de 276 professores equatorianos organizados em 70 equipes pedagógicas, que responderam a nove afirmativas presentes no instrumento. Os resultados de análise fatorial exploratória mostraram a solução unifatorial como a mais satisfatória, a qual captura 65,84% da variância do fenômeno e possui valores adequados de confiabilidade (alpha de Cronbach de 0,93). Análises de padrões de variância dentro e entre grupos revelaram que a medida permite capturar um fenômeno do nível meso. Recomenda-se a realização de outras pesquisas que verifiquem a estabilidade desta solução. Palavras-chave: desempenho no trabalho; escala de avaliação; equipes de trabalho.

<p>Based on a joint analysis of geothermal indicators (e.g. temperature map at different depth, surface heat flux) and practical features (e.g. restricted areas, existing research lease), two promising areas in southern Tuscany were identified to perform a more detailed geothermal resource characterization. An area is located on the north-east of the Larderello-Travale geothermal field, and the other one is located on the west of the Mt. Amiata geothermal field.</p><p>A quantitative geothermal resources assessment was performed in the aforementioned areas of Tuscany by solving numerical thermo-fluid dynamic models and by computing the geothermal potential using the ‘ThermoGIS’ software, as further developed for the Italian case (Trumpy et al., 2016).</p><p>First of all, geological and geophysical data required for geological and thermo-fluid dynamic modelling were collected and organised. The geological data were used to build a 3D geological model of the two areas of interest suitable for numerical simulations. Static temperature data gathered from the Italian National Geothermal Database together with site-specific heat flow measurements were used to calibrate the simulated steady state temperature distribution.</p><p>The geothermal potential computed by integrating geological, thermal and petro-physical information implementing the volume method used in ThermoGIS provided estimates of the heat in place and the geothermal technical potential maps. The resulting technical potential in the area close to Larderello –Travale is 330 MW<sub>e</sub> and in the Mt. Amiata sector is 50MW<sub>e</sub>.</p><p>References</p><p>Trumpy E., Botteghi S., Caiozzi F., Donato A., Gola G., Montanari D., Pluymaekers M., Santilano A., Van Wees, J.D., Manzella A.
