Ecologia integral e trabalhadores imigrantes na pandemia de Covid-19 / Integral ecology and immigrant workers in the Covid-19 pandemic

No período da pandemia deCovid-19 um dos grupos mais vulneráveis é aquele composto por trabalhadores imigrantes. Longe de seus países, muitos deles não recebem assistência médica ao mesmo tempo que continuam trabalhando normalmente por desempenharem funções consideradas essenciais. Além disso, encontram-seseparados de suas famílias por conta das restrições de entrada em fronteiras internacionais. Neste trabalho, queremos apresentar os princípios da ecologia integral daIgreja Católica como uma maneira de atender às necessidades mais urgentes dos trabalhadores imigrantes neste tempo da pandemia. Vamos, primeiramente,tratar da situação dos trabalhadores imigrantes com base em alguns estudos recentes. Depois explicaremos os princípios da ecologia integral segundo a doutrina social da Igreja Católica. Por fim, com base naqueles princípios, vamos propor recomendações para policy makerscom relação ao cuidado dos trabalhadores imigrantes no contexto da pandemia

At the time of the Covid-19 pandemic one of the most vulnerable groups is that composed of migrant workers. Far from their home countries, many of them do not receive medical assistance while continuing to work as they do essential jobs. In addition, they are separated from their families due to entry restrictions at international borders. In this paper, we want to present the principles of the Catholic Church's integral ecology as a way to address the most urgent needs of migrant workers in this time of pandemic. We will first address the situation of migrant workers based on some recent studies. Then we will explain the principles of integral ecology according to the social doctrine of the Catholic Church. Finally, based on those principles, we will propose recommendations for policy makers regarding the care of immigrant workers in the context of the pandemic.

Behaviour of simple population models under ecological processes.

The two most popular and extensively-used discrete models of population growth display the generic bifurcation structure of a hierarchy of period- doubling sequence to chaos with increasing growth rates. In this paper we show that these two models, though they belong to a general class of one-dimensional maps, show very different dynamics when important ecological processes such as immigration and emigration/depletion, are considered. It is important that ecologists recognize the differences between these models before using them to describe their data—or develop optimization strategies—based on these models.
