Determination of aerosol content in the atmosphere from ERTS-1 data
The author has identified the following significant results. Significant results, relating the radiance over water surfaces to the atmospheric aerosol content, have been obtained. The results indicate that the MSS channels 4, 5, and 6 centered at 0.55, 0.65, and 0.75 microns have comparable sensitivity, and that the aerosol content can be determined within + or - 10% with the assumed measurement errors of the MSS. The fourth channel, MSS 7, is not useful for aerosol determination due to the water radiance values from this channel generally being less than the instrument noise. The accuracy of the aerosol content measurement could be increased by using an instrument specifically designed for this purpose. This radiance-aerosol content relationship can possibly provide a basis for monitoring the atmospheric aerosol content on a global basis, allowing a base-line value of aerosols to be established. The contrast-aerosol content investigation shows useful linear relationships in MSS channels 4 and 5, allowing the aerosol content to be determined within + or - 10%. MSS 7 is not useful due to the low accuracy in the water radiance, and MSS 6 is found to be too insensitive. These results rely on several assumptions due to the lack of ground truth data, but do serve to indicate which channels are most useful

Reconsidering the Tribune in Early Gothic Architecture of Twelfth-Century Northern France
This work reconsiders the tribune, its functional and symbolic importance in Gothic style architecture of twelfth-century France. Three case studies, the cathedrals of Notre-Dame of Noyon and Senlis and the priory church of Saint-Leu at Saint-Leu-d’Esserent, serve as a means to examine the origins, function and medieval conceptions of this enigmatic second story. An analysis of the cathedral fabric, together with the episcopal palace and chapel, in conjunction with an examination of the sociological and political context are undertaken in an effort to start a new dialogue regarding this architectural entity, long neglected in the discourse of Gothic architecture. The outlier in this study is the Cluniac priory of Saint-Leu, constructed with a tribune-like elevation yet lacking a proper tribune; the priory serves as a foil with which to test the assumptions surrounding the cathedral case studies. The careful examination of evidence reveals a nuanced understanding of this architectural entity, undermining the traditional narrative that holds it to be purely a constructional device used by medieval builders in the race for taller, more spacious churches. This new perspective situates the tribune in the broader context of the episcopal complex as an architectural entity physically and symbolically linking the different buildings of the cathedral, episcopal chapel and palace. Finding its roots in royal and imperial architectural complexes of the Byzantine and medieval empires the tribunes of Notre-Dame of Noyon and Senlis express propriety befitting the stature of the bishop and his cathedral, while this second story as a space of devotion confirms its spiritual supremacy. Notably, the use of this architectural form at this time occurs when bishops sought to reassert their authority, following a period of institutional weakness
The impact of healthcare on global warming and human health: connecting the dots
The aim of this paper is to explore climate change and the impact that this is having on human health. The paper takes the reader through a brief history of climate change, making links between raising global temperatures and the environmental effects that are being seen across the globe. The environmental effects are then explored in relation to human health and the impact that climate change is having on physical and mental health. The paper concludes by illuminating the carbon footprint of health and care in the UK and the role of the healthcare assistant and assistant practitioner in making a positive contribution to sustainable healthcare
Nursing and the barriers to sustainable healthcare: an international review of the literature
Objectives: global warming poses a serious threat to human health yet healthcare organisations and staff have been relatively slow to engage with sustainable healthcare practises. This review of the literature seeks to frame what is already known about nurses and their views on global warming and sustainable healthcare.
Design: eleven primary research papers were sources from a search of five mainstream databases. These papers were subject to a basic thematic analysis. Results: six themes were identified: Sustainability; Endemic Blindness to Global Issues; Environmental Numbness; Social Norms; Priority Assigned to Sustainability, and; Psychology of Responsibility and Blame.
Conclusion: from the literature reviewed it is clear there are a number of social, cultural and psychological barriers which have led to widespread inaction. This article recommends further research to understand the psychological barriers in more depth as this is a poorly understood area
It\u27s Not Just a Game: Exploring the Effects of an Escape Room Team Building Intervention
Escape rooms have been used as a training intervention in multiple contexts, but their efficacy as a team building intervention is not well understood. The purpose of this study was to assess the effects of a team building escape room on perceptions of team processes and perceived team effectiveness, the sustainability of these effects, as well as relationships between team processes and task completion in this context. This research utilized archival data of 33 healthcare teams (n = 145 participants) completing a team building escape room and prospectively collected follow-up data from the same participants (n = 49 participants). Analyses indicated that team process perceptions did not significantly correlate with team process behaviors, participants’ perceptions of team processes returned to baseline after one year, and that team process perceptions and behaviors were not predictive of task completion. A significant improvement in perceived team effectiveness was observed immediately following participation in the escape room. This improvement was positively influenced by task completion. However, this effect did not persist; participants’ perceived team effectiveness returned to baseline after one year. This study has demonstrated the utility of an escape room team building intervention in improving perceptions of team effectiveness up to one month after the activity, including the positive influence of task completion on this outcome. Implications of these results and considerations for future research are discussed. This work has provided a foundation for future research to continue exploring the utility of team building escape rooms using a multi-method approach
Education and progression for support workers in mental health
Purpose: This case study details the development of a bespoke programme of learning for Support Workers employed in Mental Health sector.
Design: The programme was designed to serve three purposes: to offer a route into Mental Health Nursing; to upskill those who wanted to remain as a Support Worker; to improve the quality of care provided.
Findings: The paper shares the perspectives of the local Partnership Trust, a Support Worker on the programme and the Programme Director.
Originality/Value: Employers within the Mental Health sector are encouraged to develop their own staff and Universities are urged to think differently about curriculum design
On biembedding an idempotent latin square with its transpose
Let L be an idempotent Latin square of side n, thought of as a set of ordered triples (i, j, k) where L(I, j) = k. Let I be the set of triples (i, I, i). We consider the problem of biembedding the triples of L\I, with the triples of L'\ I, where L' is the transpose of L, in an orientable surface. We construct such embeddings for all doubly even values of n
