Nowadays, LED lighting technology reaches a higher Value of Energy Efficiency in Installations (VEEI) (W/m2*100 lux) than current luminaire lighting due to the number of lumens per watt that these are able to generate, as well as the directional nature of their emissions together with the adjustment capability through concentrator lenses with beam graduations that reach 5º. This achieves energy savings of up to 80%. Furthermore, also considering the substantial decrease in flickers, and that it noticeably improves usage of ultra-slow-motion cameras and the fading of switching-on or rearm times upon failure, LED technology stands out as the main solution for illumination of professional sports facilities. This article describes the evolution of regulatory requirements that are being imposed by the governing institutions of sports (FIFA, UEFA, FIBA, etc.) and professional leagues (LaLiga, Euroliga, etc.) in order to guarantee their competence as high-quality television products. In addition, the trends in requirements and specifications regarding lighting equipment and its installation, which are intended to convert stadiums into optimized centers for the celebration and dissemination of mass events, are analyzed (settings, photometry, etc.), particularly those concerning horizontal, vertical, and camera illuminance, average and extreme uniformities, glare, reduction of intrusive light in bleachers, flickers, color rendering index (CRI), correlated color temperature (CCT), and start-up times.

Practical Implications

This study examines the influence of familiarity on witnesses’ memory and the individual effectiveness of each of the four cognitive interview instructions in improving witnesses’ recall of scripted events. Participants (N = 195), either familiar or unfamiliar with the hospital script, were presented with a video of a surgical operation. One week later, an interviewer used one of the four cognitive interview instructions or a control instruction to ask them about the video. Participants familiar with the surgery context recalled significantly more correct information and, in particular, more consistent and irrelevant details than those unfamiliar with the surgery context. Furthermore, the results confirmed the effectiveness of all four cognitive interview mnemonics in enhancing the amount of correct information reported, irrespective of the participants’ familiarity with the critical event. However, their efficacy differed depending on the category of details considered. The practical implications of these results are discussed.

Lighting Application

The purpose of this paper is an investigation of LEDs illumination experience at US-based aerodromes with an assessment of its feasibility and its necessity in Russia. The following methods were used: the analysis of aerodrome lighting requirements; the review and the analysis of development features in aerodrome LEDs illumination; the experience analysis of LEDs illumination of US-based aerodromes; the deductive analysis and the assessment synthesis of feasibility and necessity of US experience in LEDs illumination at Russian-based aerodromes. The following results were achieved: – The analysis of issues and opportunities was conducted for development of LEDs illumination at US-based aerodromes and of American experts’ recommendations for its use; – The cases were taken for use and assessment of development in LEDs illumination at US-based aerodromes; – The review and the analysis were conducted in relation to a developing market of LEDs illumination at Russian-based aerodromes. The main conclusion is that the US experience will improve quality and reliability of service provided in air transportation, comfort, and safety of Russian flights, as well as competitiveness of Russian- based airports and airlines (indirectly).
