No full textCurrent lighting industry has transformed from increasing the lighting efficiency to more diverse and life-style designs. Autostereoscopic 3D displays employ a large array of micro-lenses to redirect different images towards the two eyes of an observer. The micro-lens arrays are required to be switchable and cost effective. Other new applications, e.g. high-efficiency sunlight concentrators for solar cells, adaptive car head lightings and auto-focusing smart contact lenses and glasses, also need the controllable beam shaping functionality with a low cost. In this PhD research, a new technology platform for the dynamic directing and shaping of light has been successfully developed. Two core technologies based on liquid crystals (LCs) are utilized: LCs combined with specially shaped polymer patterns and the LC gradient refractive index effect. Various beam steering properties are realized using the former scheme for the aforementioned different kinds of electro-optical applications. The LC gradient refractive index effect exerted by highly resistive polymer thin film also achieves beam deflection, meanwhile it also simplifies the driving circuits. These fruitful results gained from this research work, do pave the way for the large-scale applications of the LC based beam shaping devices and components

No full textThe critical role of mission valence : the impact of public service motivation and psychological empowerment on organizational identification
No full textDrawing on self-determination theory, this cross-sector study investigates how public service motivation (PSM) and psychological empowerment (PE) shape employees’ perceptions of mission valence and organizational identification. Two-wave survey data from 322 UK-based employees across public and private sectors were analyzed using multi-group structural equation modeling. Results show that mission valence mediates the relationships between PSM and PE as the predictors and organizational identification as the outcome variable. This reveals two motivational pathways: one rooted in intrinsic prosocial motivation and another in empowering work contexts. PE shows a stronger association with mission valence than PSM and moderates the PSM−mission valence link, strengthening it under high empowerment and reversing it under low empowerment. No significant sectoral differences were found, indicating that mission-driven motivation operates similarly across institutional settings. The findings advance theory by integrating psychological and contextual perspectives on purpose-driven motivation and offer practical insights for building mission alignment and engagement across sectors
Dissociable Effects of Attention and Prediction on Visual Processing: Evidence From Overlap‐Corrected Visual <scp>ERPs</scp>
No full textABSTRACT
Visual processing is influenced by spatial attention and prediction. Yet, in humans, it is still unclear if early sensory processing in the primary visual cortex (V1) is influenced by these top‐down factors. To answer this question, various EEG studies have looked at the retinotopic C1 event‐related potential (ERP), which arises from V1. Despite the fact that research on this question has been ongoing for more than two decades, discrepant findings have been reported. One reason for this heterogeneity could be due to the majority of studies focusing mostly on attention, without considering the possible role of prediction. Another reason could stem from the C1's specific sensitivities to stimulus features and individual differences. To address these issues, we developed a new paradigm that maximally utilizes the visual and spatial properties of the C1 and allows for the factorial manipulation of spatial attention and prediction. We also used gaze‐contingent eye‐tracking to confirm the use of peripheral vision to process the stimuli. Additionally, to account for the individual differences in the C1 response the experiment was tailored to each participant using an independent localizer. The ERP results showed a significantly smaller C1 amplitude in the upper visual field when attention was directed toward the peripheral stimulus as opposed to when it was directed away toward the center of the screen. After applying linear deconvolution to correct for temporal overlap between sequential ERP responses, this effect disappeared. We found that attention influenced the P1, while prediction mostly affected the P3. These novel results suggest that early sensory processing in V1 is not directly influenced by either attention or prediction; their effects are dissociable and mostly concern the P1 and P3 ERP components.</jats:p
