Academic staff is a key resource in higher education institutions (HEIs) and therefore has a major role in the achievement of the objectives of these institutions. Satisfied and well-motivated academic staff can build a national and international reputation for themselves and their institutions. Moreover, the performance of academic staff impacts student learning. In this context, the study of academic staff job satisfaction and motivation to perform their professional activities becomes crucial, especially as higher education is traversed by multiple changes. The purpose of this paper is to present and analyze the findings of a nationwide study on satisfaction and motivation of academics. All academics working in Portuguese HEIs were invited to complete a survey online. The data obtained from 4529 academics were extensively analyzed and findings are presented here along with their implications for HEIs in Portugal.

A quantity termed the total surface segregation is discussed and evaluated as a measure of relative adsorption at the gas-liquid interface of binary liquid mixtures. Its calculation from the surface tension and nonideality of the liquid mixture is detailed, and results are presented for 17 systems covering the recognized classes of liquid mixtures. The results for argon + krypton, in particular, are compared with theoretical calculations based on the density functional treatment of Telo da Gama and Evans which yields the local surface segregation whose integral through the interface is a close approximation to the total surface segregation. The absolute magnitude, composition dependence, relation to surface azeotropy (aneotropy) and bulk azeotropy, and proximity to a consolute point of the total surface segregation are explored. Useful relationships with the known underlying intermolecular forces are presented which confirm broadly the utility of the total surface segregation for the purpose of representing adsorption at the gas-liquid interface of mixtures.
