- Authentic leadership and employees’ performance: the mediating role of affective commitment and creativityPublication . Ribeiro, Neuza; Duarte, Patrícia; Ramalho, EvaThis study aims to examine how perceptions of authentic leadership explain affective commitment, creativity and employees’ performance. A second aim is to examine the mediating role of affective commitment and creativity in the relationship between perceptions of authentic leadership and employees’ individual performance. A sample of one hundred and fourteen employees belonging to several Portuguese public and private organizations was surveyed. A quantitative methodology was used. The results indicate that authentic leadership explains affective commitment, creativity and individual performance. It is also possible to verify that affective commitment totally mediates the relationship between authentic leadership and individual performance, while creativity presents only a partial mediation of this relation. With these results, it can be verified that this style of leadership has a relevant impact on employees’ attitudes and behaviours. Additional studies with larger samples are needed to determine more clearly not only authentic leadership’s influence on individual performance but also other psychosocial variables affecting that relationship. This research has practical implications for human resources management in organizations, particularly in selection processes and training and development of leaders and managers. Practitioners looking to increase employee commitment, creativity and performance can do so by augmenting the authentic leadership.
- The impact of CSR perceptions on workers turnover intentions: exploring supervisor exchange process and the role of perceived external prestigePublication . Gaudêncio, Pedro; Coelho, Arnaldo; Ribeiro, NeuzaThe purpose of this study is to determine the potential influence of the presence of CSR practices in the workplace on workers’ attitudes, particularly at Turnover Intentions (TI) level. The study intends to evaluate the importance attached to issues of CSR, to determine whether the CSR practices are influential upon workers’ TI and identify possible mediators and moderators in this link. Specifically, we consider Leader Member Exchange (LMX) as a mediator. Mallory & Rupp (2015) suggested a need for much more fine-grain theorizing with regard to the interactive effects of contextual moderators of CSR-LMX relationships. We also analyse the data to establish whether the impact of CSR practices on employees is moderated by their Perceived External Prestige (PEP), which have been rarely explored. This study’s empirical findings will contribute to solidify our knowledge about the internal mechanisms of CSR within organisations. The findings will also enhance employers understanding about the role of CSR and organisational image at individual employer level behaviour. The investigation uses cross-sectional data obtained from a sample of private sector workers. Data collection is based on a structured questionnaire, and structural equations modelling are employed to test the proposed model.
- Performance of cutting tools in millingPublication . Wilson, Vijay Bakkiyalashmi; Simões, Fábio Jorge PereiraThis report contains the experience, training and knowledge gained throughout the internship program that where completed in the company DGP moulds. The report mainly concentrates on CNC machining and the case study done on performance of milling tool. Apart from this the report starts my explaining the basic knowledge obtained on mould production and about mould tool that produces plastic product output. The main value of this report lies on the case study explored in tool wear which shows the better result on performance of milling tool which helps in improving the mould products in even better way to success.
