Research work analyses current situation and development of tourism in the region of Baltic Sea. Specific case study of this paper is Pärnu Bay, Estonia. This region is known for unique environmental settings: mild maritime climate, broad beaches, coniferous pine forests on the coastal zone and high aesthetic value of the surrounding landscapes. However, after the end of USSR, Estonia survived a [...]
Simulated environmental photo- and auto-oxidation of ambrein
Published: 2018-11-12
Subjects: Environmental Sciences, Medicine and Health Sciences, Other Environmental Sciences, Physical Sciences and Mathematics
In alcoholic solutions (tinctures), the tricyclic triterpenoid alcohol, ambrein, which is usually the main ingredient of the natural product ambergris, undergoes photo-oxidation to a number of odorous products. Such tinctures are valuable in perfumery. Similar reactions are thought to occur in the marine environment, when flotsam and jetsam ambergris are exposed to sunlight. However, [...]
Creating a Model to Optimize and Evaluate the Heat-Reducing Capacity of Green Infrastructure

As global warming increases temperatures worldwide, cities are experiencing even greater temperatures due to the urban heat island effect, which is the trapping of heat in “gray” urban infrastructure. Cities are combatting this with green infrastructure (GI) initiatives, such as the Department of Environmental Protection (DEP) GI initiative in New York City. However, these programs are often [...]
Powers of 10: cross-scale optimization of social agencies for rapid climate and sustainability action
Published: 2018-08-27
Subjects: Education, Environmental Sciences, Environmental Studies, Geography, International and Area Studies, Library and Information Science, Life Sciences, Medicine and Health Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences, Sustainability
Achieving the goals of the Paris Agreement and related sustainability initiatives will require halving of greenhouse gas emissions each decade from now on through to 2050, when net zero emissions should be achieved. To reach such significant reductions requires a rapid and strategic scaling of existing and emerging technologies and practices, coupled with economic and social transformation and [...]
Knowledge in the Dark: Scientific Challenges and Ways Forward

We propose the concept of knowledge in the dark – or short: dark knowledge – and outline how it can help clarify why in our current era of Big Data, the knowledge (i.e. evidence-based understanding) of people does not seem to be substantially increasing despite a rapid increase in produced data and information. Key reasons underlying dark knowledge are: (1) the production of biased, erroneous or [...]
