Influence of the perception of discrimination on women's work motivation

Nowadays, despite anti-discrimination policies, women suffer frequently from a lack of consideration from their male colleagues, altering their well-being and motivation to work. More precisely, perceived personal or groupal discrimination, could have a distinct influence on work motivation. Previous studies showed that the impact on women varies in function of the type of perceived discrimination (Bourguignon et al. 2006). Based on the self-categorization and the social identity theory, work motivation is differently structured as if employees categorized themselves as individuals or as part of a group. As a result, a different impact from personal and group discrimination on work motivation is expected. Moreover, it has been proved that typical men behavior is heavily associated with competence compared to women behavior (Marchand, Saint-Charles & Corbeil, 2007). Therefore, it is hypothesized that women with more masculine traits will suffer from less perceived discrimination, and work motivation. An online survey was created in order to collect data over work motivation, perceived personal and group discrimination. The respondents were also questioned on typical men and women behavior to determine their gender-conformity. To test our hypotheses, data were collected from 57 women stemming from the labour force, aged from 21 to 63 years old. Results indicate that perceived personal discrimination was negatively related to work motivation and that perceived group discrimination was negatively correlated with masculine behavior. Thereby, our study enhances the importance of work environment, and especially discrimination, on work motivation. This research also corroborates the self-categorization and the social identity theory framework to study these issues.

Mixed self-assembled monolayers of 2-mercaptobenzimidazole and 2-mercaptobenzimidazole-5-sulfonate: determination and control of the surface composition

The behaviour towards electron transfer of self-assembled monolayers of 2-mercaptobenzimidazole (MBI) and 2-mercaptobenzimidazole-5-sulfonate (MBIS) on Au(1 1 1) was examined by cyclic voltammetry. The influence of the monolayers was drastically dependent on the charge of the redox probe used. When [Ru(NH3)6]3+ is used, a post-adsorption peak characteristic of the adsorption of the redox probe is detected only at the MBIS modified electrode. Taking advantage of this difference, ac voltammetry has been used to determine the surface composition when mixed monolayers are formed by immersion of the gold substrate in mixtures of different molar fractions of MBI and MBIS. Results clearly indicate that the ionic strength of the immersion solution plays a key role in the surface composition when a charged surfactant is mixed with non-charged surfactant. © 2006 Elsevier B.V.
