The aim of this study is to determine the contribution of student interventions to urban greening processes. In two Dutch cities action research was conducted, including reflexive interviews a year after the first intervention, to assess factors causing change in the socio-ecological system. Results show that students and network actors were mutually learning, causing the empowerment of actors in that network by adding contextualized knowledge, enlarging the social network, expanding the amount of interactions in the socio-ecological system and speeding up the process. Students brought unique qualities to the process: time, access to stakeholders who tend to distrust the municipality and a certain open-mindedness. Their mere presence made a difference and started a process of change. However, university staff needed to keep the focus on long-term effects and empowerment, because students did not oversee that. After a year, many new green elements had been developed or were in the planning phase. In Enschede, the municipality districtmanagers were part of the learning network, which made it easier to cause changes in the main ecological network. In Haarlem however, no change took place in the main ecological network managed by the municipality, because no political empowerment of the civil society group had developed yet.

This study investigates the mediating role of organizational citizenship behaviours (OCBs) on the leader-member exchange (LMX) and employee performance relation and the degree to which work experience moderates the relation between leader-member exchange and OCBs. Lecturers from six technical universities in Ghana, making up three hundred and thirty-six lecturers, were selected using convenience sampling. The participants completed self-administered surveys. OCBs fully mediated the association between LMX and employee performance. Furthermore, the findings indicate that the interplay between LMX and work experience on OCBs is compensatory in nature such that as work experience increases, the positive association between LMX and OCBs decrease. Managers of higher education institutions should create enabling work environments that encourage high-quality LMX and citizenship behaviours. Moreover, as work experience tends to attenuate the positive influence of LMX on OCBs, managers in higher education should focus their attention on employees with low rather than high work experience. This research adds to the employee performance literature through examining a novel link among leader-member exchange, organizational citizenship behaviours and performance.
