This study explores the relationship between academic motivation, Machiavellian traits, and lying tendencies among Romanian engineering students, with a focus on how these psychological variables influence academic performance. Data were collected from 706 students using the MUSIC Model of Motivation, the Machiavellianism Scale, and the Lie Attitude Questionnaire. Statistical analysis included Spearman correlations, regression models, and moderation analysis using PROCESS Macro (Model 7). The results showed significant negative correlations between Machiavellianism and all five motivational dimensions (e.g., ρ = −0.259 for Empowerment, p < 0.001), as well as between lying tendencies and motivation (e.g., ρ = −0.206 for Empowerment, p < 0.001). Surprisingly, Machiavellianism had a positive effect on academic grades (β = 0.107, p = 0.043), suggesting strategic academic behavior. Motivation was a stronger predictor of performance among female students. These findings highlight the importance of promoting ethical, intrinsic motivation in university settings and call for thoughtful integration of behavioral variables into academic success models.

This paper examines the influence of managerial styles on employee productivity and performance in Romania’s textile industry, using Company T as a case study. The study is based on a quantitative survey applied to 46 employees across production and administrative departments, combined with statistical analyses (Cronbach’s Alpha, Shapiro–Wilk, and Spearman correlations) to ensure the reliability and validity of results. Findings show that participative and transformational leadership styles are most strongly associated with higher productivity, job satisfaction, and professional development, particularly among office employees, while authoritarian and laissez-faire styles were more evident in production and linked to lower motivation and work quality. The results confirm that managerial adaptability is crucial in dynamic industrial contexts, and highlight the importance of transparent communication, frequent feedback, and professional development opportunities. The study contributes to leadership literature by providing empirical evidence from a traditional sector undergoing modernization and offers practical recommendations for strengthening organizational performance through flexible and employee-centered management practices.
