Direct assessment of the sensitivity drift of SQM sensors installed outdoors
2021
Long-term monitoring of the evolution of the artificial night sky brightness is a key tool for developing science-informed public policies and assessing the efficacy of light pollution mitigation measures. Detecting the underlying artificial brightness trend is a challenging task, since the typical night sky brightness signal shows a large variability with characteristic time scales ranging from seconds to years. In order to effectively isolate the weak signature of the effect of interest, determining the potential long term drifts of the radiance sensing systems is crucial. If these drifts can be adequately characterized, the raw measurements could be easily corrected for them and transfor…

Precipitable water vapour content from ESR/SKYNET sun-sky radiometers: validation against GNSS/GPS and AERONET over three different sites in Europe
2018
The estimation of the precipitable water vapour content (W) with high temporal and spatial resolution is of great interest to both meteorological and climatological studies. Several methodologies based on remote sensing techniques have been recently developed in order to obtain accurate and frequent measurements of this atmospheric parameter. Among them, the relative low cost and easy deployment of sun–sky radiometers, or sun photometers, operating in several international networks, allowed the development of automatic estimations of W from these instruments with high temporal resolution. However, the great problem of this methodology is the estimation of the sun-photometric calibration par…

Distraction of cyclists: how does it influence their risky behaviors and traffic crashes?
2018
BackgroundUndisputedly, traffic crashes constitute a public health concern whose impact and importance have been increasing during the past few decades. Specifically, road safety data have systematically shown how cyclists are highly vulnerable to suffering traffic crashes and severe injuries derived from them. Furthermore, although the empirical evidence is still very limited in this regard, in addition to other human factors involved in cycling crashes, distractions while cycling appear to be a major contributor to the road risk of cyclists.ObjectivesThe main objectives of this study were, first, to explore the prevalence and trends of cycling distractions within an international sample o…
Entryism in the British Labour Party, 1920- 1992
2022
This work aims at studying entryism in the context of the revolutionary socialist left in Britain, from the inception of the Communist Party of Great Britain in 1920 to the departure of Militant, the largest entryist organisation of the Kingdom, from the Labour Party in 1992.Entryism, which is often at the heart of political myths, is a tactic of penetration of a political party by another, aiming at accomplishing objectives, the nature of which can change depending on the type of entry. The intention of this study is to show to what extent there is not one type of entryism but several ones.The adopted methodology is chronological. The first part is dedicated to the relationship between the…
