Abstract: To investigate how nursing experts and experts from other health professions understand the concept of rationing/missed/unfinished nursing care and how this is compared at a cross-cultural level. The mixed methods descriptive study. The semi-structured questionnaires were sent to the s le of 45 scholars and practitioners from 26 countries. Data were collected from November 2017-February 2018. Assigning average cultural values to participants from each country revealed three cultural groups: high in idualism-high masculinity, high in idualism-low masculinity and low in idualism-medium masculinity. Content analysis of the findings revealed three main themes, which were identified across cultural clusters: (a) projecting blame for the phenomenon: Blaming the nurse versus blaming the system (b) intentionality versus unintentionality and (c) focus on nurses in comparison to focus on patients. Consistent differences in the understanding of missed nursing care can be understood in line with the nation's standing on two main cultural values: in idualism and masculinity. The findings call for scholars' caution in interpreting missed nursing care from different cultures, or in comparing levels and types of missed nursing tasks across nations. The findings further indicated that mimicking interventions to limit missed nursing care from one cultural context to the other might be ineffective. Interventions to mitigate the phenomenon should be implemented thoughtfully, considering the cultural aspects.

Abstract: The night has historically been neglected in both disciplinary and interdisciplinary research. To some extent, this is not surprising, given the diurnal bias of human researchers and the difficulty of performing work at night. The night is, however, a critical element of biological, chemical, physical, and social systems on Earth. Moreover, research into social issues such as inequality, demographic changes, and the transition to a sustainable economy will be compromised if the night is not considered. Recent years, however, have seen a surge in research into the night. We argue that “night studies” is on the cusp of coming into its own as an interdisciplinary field, and that when it does, the field will consider questions that disciplinary researchers have not yet thought to ask.

Abstract: The VIIRS day/night band (DNB) high gain stage (HGS) pixel effective dwell time is in the range of 2–3 milliseconds (ms), which is about one third of the flicker cycle present in lighting powered by alternating current. Thus, if flicker is present, it induces random fluctuations in nightly DNB radiances. This results in increased variance in DNB temporal profiles. A survey of flicker characteristics conducted with high-speed camera data collected on a wide range of in idual luminaires found that the flicker is most pronounced in high-intensity discharge (HID) l s, such as high- and low-pressure sodium and metal halides. Flicker is muted, but detectable, in incandescent luminaires. Modern light-emitting diodes (LEDs) and fluorescent lights are often nearly flicker-free, thanks to high-quality voltage smoothing. DNB pixel footprints are about half a square kilometer and can contain vast numbers of in idual luminaires, some of which flicker, while others do not. If many of the flickering lights are drawing from a common AC supplier, the flicker can be synchronized and leave an imprint on the DNB temporal profile. In contrast, multiple power supplies will throw the flickering out of synchronization, resulting in a cacophony with less radiance fluctuation. The examination of DNB temporal profiles for locations before and after the conversion of high-intensity discharge (HID) to LED streetlight conversions shows a reduction in the index of dispersion, calculated by iding the annual variance by the mean. There are a number of variables that contribute to radiance variations in the VIIRS DNB, including the view angle, cloud optical thickness, atmospheric variability, snow cover, lunar illuminance, and the compilation of temporal profiles using pixels whose footprints are not perfectly aligned. It makes sense to adjust the DNB radiance for as many of these extraneous effects as possible. However, none of these adjustments will reduce the radiance instability introduced by flicker. Because flicker is known to affect organisms, including humans, the development of methods to detect and rate the strength of flickering from space will open up new areas of research on the biologic impacts of artificial lighting. Over time, there is a trend towards the reduction of flicker in outdoor lighting through the replacement of HID with low-flicker LED sources. This study indicates that the effects of LED conversions on the brightness and steadiness of outdoor lighting can be analyzed with VIIRS DNB temporal profiles.
