The study investigated the potential role of human resources exemplified by leaders' psychological capital (PsyCap) as a resource that may cross over to team-member exchange (TMX), and bring about desired organizational outcomes. We suggest a model where TMX of senior management teams serves as a team resource mediating the relationship between leaders’ PsyCap and organizational outcomes, as represented by team innovation, organizational citizenship behavior (OCB), and employees’ job satisfaction. The study, carried out among 86 elementary and junior high schools, indicated a positive relationship between leaders’ PsyCap and TMX. In addition, we found a significant relationship between TMX and the three measures of organizational outcomes. Furthermore, TMX partially mediated the relationship between leaders’ PsyCap and the desired outcomes, excepting innovation. The findings provide support for the importance of the leaders’ personal resource of psychological capital as a complementary perspective that may enhance our understanding of leadership’s impact on organizational success. In addition, the study provides significant support for the expanded model, broadening the definition of the crossover model by examining the translation of positive resources from leaders' PsyCap to organizational outcomes via teams' positive resources. From a practical perspective, the findings bring to the forefront the importance of psychological capital as a state-like construct that can be developed through leader preparation and professional development programs.

The research's aim is to assess the services offered by Greek public secondary education schools, with the intention of identifying any discrepancies between students' expectations and their perceptions of the final services provided. The gaps discovered indicate that the school's educational services are not meeting student expectations in the five quality dimensions of the SERVQUAL model. To be specific, the average expectations are 4.44, perceptions are 3.11, and gaps are -1.33. The schools examined had a greater discrepancy in the dimensions measuring safety and emotional understanding, which was observed. The fact that the 5 factors are correlated with each other indicates the model's reliability. However, in relation to the independent variables of gender, age, and class, there appears to be a positive correlation across all factors, which is very weak and not statistically significant. In contrast, a low negative correlation appears to be present between only the demographics being considered. Therefore, demographic characteristics do not affect the quality of education in secondary schools. Our findings benefit decision-makers by assisting them in taking corrective actions necessary to enhance the quality of services provided by schools as part of a continuous improvement process in order to achieve a higher level of excellence.
