The Art of Teaching Professional Practice: An Action Research Methodology Inspired by Ulrich's Systems Concepts.

Learning the art of any professional practice like engineering design or computer programming is a challenge for students and adds to the complexity of teaching such a technical discipline. Institutional regulations, along with industry expectations, increase the burden on the educator to develop a successful instructional environment. Critical systems thinking provides practitioners, in general, with a framework for understanding interrelation and complexities in a variety of problem situations.

Low-Threshold Testing for SARS-CoV-2 (COVID-19) in Long-Term Care Facilities Early in the First Pandemic Wave, the Twente Region, the Netherlands: A Possible Factor in Reducing Morbidity and Mortality.

During the first wave of the COVID-19 pandemic, there was a shortage of SARS-CoV-2 diagnostic tests, and testing patients with mild symptoms (low-threshold testing) was not recommended in the Netherlands. Despite these guidelines, to protect those who were most at risk, low-threshold testing was advocated and offered to the majority of long-term care institutions in the region. In this manner, 144 healthcare workers and 96 residents tested SARS-CoV-2-positive and were isolated before the same service was provided nationwide by public health services.

A global database of soil nematode abundance and functional group composition.

As the most abundant animals on earth, nematodes are a dominant component of the soil community. They play critical roles in regulating biogeochemical cycles and vegetation dynamics within and across landscapes and are an indicator of soil biological activity. Here, we present a comprehensive global dataset of soil nematode abundance and functional group composition.

Reduced tillage, but not organic matter input, increased nematode diversity and food web stability in European long-term field experiments.

Soil nematode communities and food web indices can inform about the complexity, nutrient flows and decomposition pathways of soil food webs, reflecting soil quality. Relative abundance of nematode feeding and life-history groups are used for calculating food web indices, i.e.
