Within a wider research line on policy-driven institutional discourses on migration by international/national institutions, NGO and political leaders, this contribution is aimed at illustrating the bipolarized social representations of immigrants inspiring 24 speeches by Pope Francis and US President Donald Trump. Statistical analyses using IRAMUTEQ included "specificity analysis" of discursive forms (words) and "cluster analysis." Results show that the Pope's discourse on migration (articulated into four clusters) is richer than the oversimplified Trump's discourse (originating just one cluster): the words "bridges" and "walls" emerge as representational nuclei of their bipolarized views of transnational migration, as metaphorical dichotomies of inclusive/exclusive policies. Emphasizing the need to build to protect the Americans, inspired by the sovereign ideology (AMERICA FIRST!), does not at all suspect that in the globalized interconnected world the AMERICA FIRST may become just AMERICA ALONE!

Air pollution is the leading environmental risk to public health demanding urgent action. While air quality monitoring provides crucial insights into pollution levels, source apportionment (SA) is essential for identifying pollution sources and informing targeted solutions. However, SA remains underutilized, primarily due to the high costs of data collection.

Recent evidence suggests short-term exposure to particulate matter (PM) air pollution can impact brain function after a delay period. It is unknown whether effects are predominantly due to the olfactory or lung-brain pathways. In this study 26 adults (M = 27.

The rapid development of low-cost sensors provides the opportunity to greatly advance the scope and extent of monitoring of indoor air pollution. In this study, calibrated particle matter (PM) sensors and a non-negative matrix factorisation (NMF) source apportionment technique are used to investigate PM concentrations and source contributions across three households in an urban residential area. The NMF is applied to combined data from all houses to generate source profiles that can be used to understand how PM source characteristics are similar or differ between different households in the same urban area.

Globally, the transport sector is a major contributor to air pollution. Currently, in the UK, vehicle emissions contribute significant amounts of nitrogen oxide (NOx) and particulate matter (PM) pollution in urban areas. Low-emission-zone policies have been used as an intervention to tackle air pollution, and in this context, the UK launched the Low-Traffic Neighbourhood scheme.
