Many living organisms, such as fish, marine mammals, algae, plants, and so on, call the oceans home. They also assist humans in a variety of ways. However, this environment is currently in grave jeopardy. Over the decades, the fast-growing human population has resulted in a rise in human demands and wants, resulting in more production and waste, as well as more pollutants released into the environment, especially the oceans. This research focuses on the different types and sources of pollution and pollutants in the marine ecosystem, as well as the effects and consequences that pollution can have on water quality and living creatures, particularly pollution from wastes and its influence on oxygen production. An online survey, addressing people of various ages, places, and vocations, is used to investigate people's awareness, and understanding. The quantitative responses are then compiled and analyzed to form a basis for a deeper understanding of how the danger can be mitigated. While the purpose of the study is to increase people’s awareness and understandings of the pollution in the oceans and the marine ecosystems and seek measures to decrease the pollution released recommendations will be formulated on the basis of the international literature and the quantitative research's results. 2021-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/36710 Why can’t we have nice things – a transaction economy model of information system usability in firms Németh, Adam Kelemen-Erdos, Aniko; Feher-Polgar, Pal; Popovics, Anett Poor usabilty of B2B applications is nothing new, every scientific database is full of articles on how to improve them, but why does it happen in the first place? Turns out the answer might lie in transaction economics, once we view the purchase and use as different transactions. But buying a bad used car (a “lemon”) in the market is also nothing new – what new is that getting rid of IT is hard, because usage itself increases costs of switching to a new supplier. Most papers either deal with the internal workinsg of a software development company, or treat technology as something developed internally – yet this is rarely the case anymore, and buyer-seller relationships of technology, along with caveats in the SaaS licensing scheme might give us the answers on the sorry state we might find ourselves in. 2021-01-01T00:00:00Z
