The aim of the paper was to analyse relations between power in professional work and in close sexual relationships. Power in professional work was analysed with respect to the managerial position, the number of subordinates and salary. Power in close sexual relationships was determined on the basis of a sense of reinforcement of power as a sexual motivation, a propensity for sexual domination, the sense of power in relations with a partner in a close relationship, sexual assertiveness, realization of one’s own sexual phantasies and inclination to initiate sexual activity. The research was carried out on a group of 205 participants in which 100 of respondents occupied managerial positions at work and 105 were subordinates. The following tools were used: the Sense of Power Scale (Anderson, John, & Keltner, 2012), the Multidimensional Sexuality Questionnaire (Snell, Fisher, & Walters, 1993), the AMORE scale (Hill & Preston, 1996), the Need for Power and Influence Questionnaire (Bennett, 1988) and a data sheet. The results showed that power in the workplace was correlated a more frequent initiation of sexual activity, greater assertiveness in sexual matters, more frequent realisation of one’s own phantasies and an increased propensity for sexual domination.

In a previous study, the endophytic Bacillus velezensis NC318 was isolated from the rhizosphere of date palm and showed strong antifungal activity against the soil-borne plant pathogenic fungus, Sclerotium rolfsii Sacc, the causal agent of Southern blight. The potential of the Bacillus genus in the inhibition of plant pathogens is mainly due to the production of certain bioactive compounds. In the present study, secondary metabolites extracted from the cell-free supernatant of strain NC318 showed strong antifungal activity on the mycelial growth and germination of S. rolfsii sclerotia in vitro. With 50 μl of bioactive compounds crude extracts, the mycelial growth inhibition rate was 97% and any germination of sclerotia was reported. Chemical analysis of the secondary metabolite crude extracts performed by high performance liquid chromatography coupled with mass spectrometry (HPLC/MS), revealed that the secreted bioactive compounds belonged to the family of lipopeptides (iturin, fengycin, surfactin), polyketides (bacillaene, macrolactin, difficidin and bacilysin) and siderophores (bacillibactin). These results provide a better understanding of the biocontrol mechanism of the bacteria strain B. velezensis NC318 against the soil fungal pathogens, especially S. rolfsii root rot.
