  • The role of management on gender (in) equality and offensive behaviors in higher education: addressing work-life balance culture and work-family conflict
    Publication . Sobral, Tiago; Vieira dos Santos, Joana; Giger, Jean-Christophe; Teodosio, Maria
    Despite the numerical predominance of women in higher education institutions (HEIs), significant underrepresentation in academic and leadership positions persists, highlighting ongoing gender inequalities. This study examines the role of management in addressing gender disparities and offensive behaviors within a Portuguese public HEI, using psychosocial safety climate (PSC) theory as a conceptual framework. We conducted two studies involving 405 participants-students and staff-to assess perceptions of gender equality and the impact of a management-promoted work-life balance culture (WLBC). Our findings reveal that active management engagement in gender equality is significantly correlated with reduced perceptions of gender inequality among both students and staff. However, gender differences emerged, with female participants reporting a higher perception of gender inequality. Despite notable improvements in gender perceptions, the reduction in reported offensive behaviors was not statistically significant, underscoring the complexity of addressing such behaviors through management interventions alone. Mediation analyses indicated that WLBC indirectly influences perceptions of gender inequality and offensive behaviors through its impact on work-family conflict (WFC), highlighting WFC as a significant mediator. This research underscores the importance of a proactive managerial approach in fostering an inclusive academic environment and demonstrates the nuanced role of WLBC and WFC in mediating gender equality outcomes.

  • A comprehensive comparative study of quick invariant signature (QIS), dynamic time warping (DTW), and hybrid QIS + DTW for time series analysis

    This study presents a comprehensive evaluation of the quick invariant signature (QIS), dynamic time warping (DTW), and a novel hybrid QIS + DTW approach for time series analysis. QIS, a translation and rotation invariant shape descriptor, and DTW, a widely used alignment technique, were tested individually and in combination across various datasets, including ECG5000, seismic data, and synthetic signals. Our hybrid method was designed to embed the structural representation of the QIS with the temporal alignment capabilities of DTW. This hybrid method achieved a performance of up to 93% classification accuracy on ECG5000, outperforming DTW alone (86%) and a standard MLP classifier in noisy or low-data conditions. These findings confirm that integrating structural invariance (QIS) with temporal alignment (DTW) yields superior robustness to noise and time compression artifacts. We recommend adopting hybrid QIS + DTW, particularly for applications in biomedical signal monitoring and earthquake detection, where real-time analysis and minimal labeled data are critical. The proposed hybrid approach does not require extensive training, making it suitable for resource-constrained scenarios.
