The research is justified by the need for organizations to maintain positive organizational climate in the pursuit of productivity and competitiveness. Research indicates that after the judicial prisons and asylums is within organizations that these personalities cause enormous damage. The study aims to identify the action of corporate psychopath within organizations and its consequences to the organizational climate. To this end it carried out a literature review and a quantitative research with employees of public and private companies. It was observed that these personalities exist within organizations, are identified by colleagues and actually cause inconvenience and loss to businesses. It is the management of people trying to prevent their entry in the companies or developing a strong organizational culture that becomes a barrier to the operation of these ...

Several problems are encountered in engineering processes that have adverse effects on the reliability of complex engineering systems. Hence, the aim of this work is to optimize the hardened steel turning process by applying mathematical methods to reduce dimensionality and eliminate the correlation between the multiple responses. The resultant latent response surfaces and their respective targets constitute the normalized multivariate mean square error (MMSE) function that is minimized by the normal boundary intersection (NBI) method. Furthermore, a fuzzy algorithm is applied to identify the best solution from several feasible solutions of the Pareto frontier that is compared with the performances of normalized normal constraint, arc homotopy length, global criterion method, and desirability method. The results show that NBI-MMSE has a higher performance than the other methods. In addition, NBI-MMSE is tested with benchmark functions to evaluate its effectiveness and robustness. Therefore, NBI-MMSE identifies the dynamics of the turning process of AISI H13 steel by revealing the optimal solutions for the input process parameters.
