Offshore petroleum exploration has increased the risks of oil spills in coastal tropical and subtropical habitats. Monitoring tools are needed to assess and protect environmental health. We determined baseline values of antioxidant biomarkers (CAT, SOD, GPx, GST, MDA) for five ecologically relevant species in a subtropical system in southern Brazil. Regional baseline levels are compared with literature ...

his study considers temporal aspects of livelihood adaptation in times of turmoil by drawing on interviews with informal street vendors in Facatativá, Colombia. By engaging a ‘time stories’ perspective, this article aims to provide a better understanding of how livelihood responses to shocks emerge from (and are constrained by) individuals’ initial and changing assumptions about the continued ...

With organizational environments becoming increasingly complex and volatile, the concept of “organizational resilience” has become the “new normal”. Organizational resilience is a complex and multidimensional concept which builds on the myriad of capabilities that an organization develops during its lifecycle. As learning is an inherent and essential part of these developments, it has become a ...

In this article, we set out to reconcile a general conceptualization of disaster temporalities by drawing on the epitome example of a creeping disaster, namely famine. Our argument is driven by the recognition that slowly manifesting disaster impacts pose distinct challenges for decision makers and researchers while there is a tendency for the disaster literature to overlook the role of disaster ...

The focus on challenges related to digital distance learning has become particularly relevant since educational institutions had to close due to the Covid-19 pandemic. Teaching related to operationally oriented professions, such as e.g., aviation and nautical represent educations that have faced extensive challenges. Education portfolios for such professions contain subjects that require transfer ...

Mining is becoming increasingly vulnerable to the effects of climate change (CC). The consequences of changing weather patterns, such as extreme weather events that can damage equipment, infrastructure, mining facilities, and operation interruption, are the source of the vulnerability. The new demand initiated by governments and international agreements put extra pressure on mining industries to ...

Column leaching test was applied for oxide and non-oxide tailings in the Arctic area. Physico-chemical parameters (pH, pe: potential ecolotric, conductivity, TDS: Total dissolved solids, SO4 2−, salinity, Ni, Co, Zn and Mn) were measured to identified the effect of oxidized degree on heavy metals leaching from tailings. Results showed that oxidized tailings contained higher levels of Co and Ni, and ...

This paper conducts a systemic comparative study on univariate and multivariate wind power forecasting for five wind farms inside the Arctic area. The development of wind power in the Arctic can help reduce greenhouse gas emissions in this environmentally fragile region. In practice, wind power forecasting is essential to maintain the grid balance and optimize electricity generation. This study first ...
