Leadership, downshifting and the experience of power in higher education.
… Focusing on two discourses, leadership and downshifting, this study explores the identities of nine Principal Lecturers within one post-1992 university. Through a discursive analysis of focus group and interview data, and institutional points of contact including; consultation documents, …

Principles of quantum dot photophysics and applications to luminescent downshifting
… region through a process called luminescent downshifting. Chapters 2-5 will explore the application of luminescent downshifting from the near-ultraviolet to the short-wavelength infrared, the far-ultraviolet to the visible, and the ultraviolet to the mid-wavelength infrared. Unique challenges …

Design and Characterisation of Hybrid Organic-Inorganic Materials for Luminescence Downshifting Devices
… UV to visible light through luminescence downshifting. Downshifting devices typically consist of a luminescent component, such as organic lumophores, and a host matrix. The host matrix is commonly composed of organic polymeric materials; however, these can suffer from poor processability …

The development of nonlinear surface and internal wave groups
… and group length. Dissipation and frequency downshifting were important characteristics of the long-time evolution. The amplitude and phase modulations were obtained using the Hilbert transform and specified as an initial condition to the cubic nonlinear Schrodinger equation, which was solved …

Hydrodynamic Characterisation and Wave Current Interaction around Dunnet Head in the Pentland Firth with Implications for Marine Energy Generation
… wave direction, and clear evidence of frequency downshifting on opposing currents and upshifting on following currents was shown in wind waves. Once an understanding of the local hydrodynamics was obtained, this was applied to the context of marine energy generation to highlight the implications …

Materials and design strategies for solar microcells
… For the project discussing the ultraviolet downshifting material, a Eu-based inorganic complex has beneficial effects on the overall cell performance. Experimental measurements on InGaP microcells showed improved performance in the ultraviolet portion of the spectrum where iii the …

Something made me doubt myself : a descriptive case study of the effects of teaching online during the Covid-19 pandemic on teacher self-efficacy.
In the spring of 2020, the COVID-19 pandemic caused policymakers to mandate school closures. Teachers left the familiar in-person classroom environment and began teaching in an unfamiliar virtual setting with little to no training. This sudden switch caused them to downshift in their pedagogical …
