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 http://hdl.handle.net/20.500.14044/36704 Creative as a sustainable career in Africa Agyare, Eric; Narelle Atiase, Joycelyn Kelemen-Erdos, Aniko; Feher-Polgar, Pal; Popovics, Anett Art is a way of life (Bauman, Z. 2013) as "Artitude" epitomises freedom of selfbelief and grassroots expression of the African connect. The creative arts industry is seen as low-hanging fruit for a lot of economies, especially in Africa. Very little attention is given to the creative arts industry, albeit a multi-billion industry in other parts of the world. Numerous people in Africa may have a depraved perception of people pursuing art programmes, especially pupils in high school. Although there are some remarkable successful art stories, numerous people still don't perceive art as a sustainable career. Parents and guardians are still indifferent and sceptical about their children pursuing courses in the creative trade but would be quick to hail science and business-related courses. How do can we change these misconceptions? The research collects key insights from various stakeholders (students, parents, institutions, artists(es), agencies, and the general public) in Ghana, and also define the social and cultural indicators connected to these misconceptions. The document would further highlight the execution of an initiative (pilot project) with the sole objective of demystifying this misconception amongst all stakeholders. It highlights the model and findings of the employed strategy. The execution strategy was categorised into four core areas: Workshop, Expose, Mentorship and Internship. This gave young creatives a platform to interact with practising creatives in commercial and non-commercial art spaces. Parents and institutions also took turns to engage practising creatives, to understand their ways and the relevance of art in society. The research indicates the impact and lessons from the initiative. The document further analyses how a perfect synergy of positive perception in arts can build a stronger creative economy in Africa 2021-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/36701 Bullwhip effect for all? Non-sensitive supply chains Strommer, Diana Kelemen-Erdos, Aniko; Feher-Polgar, Pal; Popovics, Anett bullwhip effect (BWE) is a phenomenon that is highly in focus due to the impact on supply chain performance and financial results. It is necessary to keep focus on the phenomenon, but the cases need to be determined when investigation is relevant. The aim of this paper is the determination of the operational supply chain characteristics that makes the occurrence of the BWE less likely. This shows what are the attributes need to be checked to define if the examined chain or echelon is immune or not for the bullwhip effect. In this article the investigation is based on the triggering factors of the phenomenon. These causes are paired with the operational supply chain characteristics. Based on that we can define the key factors that are showing if the examined chain’s operation is relevant or not for the occurrence of bullwhip effect. Beside the importance of tracking and elimination of the bullwhip effect we also need to consider that the phenomenon is not relevant for all product and supply chain type. 2021-01-01T00:00:00Z
