Microbiome response to foam fractionation and ozonation in RAS
2022
Efficient water treatment is required to maintain high water quality and control microbial growth in recirculating aquaculture systems (RAS). Here, we examined the effects of two treatment methods, ozonation and foam fractionation, separately and combined, on the microbiology in twelve identical experimental RAS with rainbow trout (Oncorhyncus mykiss) during 8 weeks. Microbes suspended in water and growing in biofilter biofilms were examined using flow cytometry analysis and high throughput sequencing of the 16S rRNA gene. The results showed that foam fractionation did not cause large changes in abundance or overall community composition of free-living microbes. Instead, through decreasing …
Authoritarian Neoliberalism : Its Ideological Antecedents and Policy Manifestations from Carl Schmitt’s Political Economy of Governance
2018
The regime of authoritarian neoliberalism is underway. In contemporary political economy of governance, this regime has been construed as a crisis response of the capitalist class to manage the conflict-ridden consequences of economic globalization; and, as an ideological project of a section of the ruling elites to justify the embedding of market-oriented development processes in a politically repressive government institution. To contribute to recent scholarship attempts at defining the character and tendencies of this emergent regime, the article traces one of its key ideological antecedents from Carl Schmitt’s earlier formulation for a “strong state, free economy”. It then presents a su…
Filtration of Nordic recirculating aquaculture system wastewater : Effects on microalgal growth, nutrient removal, and nutritional value
2021
Microalgal bioremediation of recirculating aquaculture system (RAS) wastewater represents an alternative for wastewater treatment with the potential to generate valuable biomass. This study evaluated the effects of removing biological contamination and suspended solids from Nordic area RAS wastewater through filtration with 0.45 μm filters on the performance and nutritional value of microalgae. All three tested green microalgae (Haematococcus pluvialis, Monoraphidium griffithii, and Selenastrum sp.) were able to grow in raw (unfiltered) and filtered RAS wastewater. Cultivation in raw RAS wastewater decreased the ω-3 and ω-6 fatty acid content of H. pluvialis as compared to filtered wastewat…
Socio-cultural lock-ins and the difficulty of sustainability transition in fertilization : response to Struckman
2021
This commentary discusses the socio-cultural context of farming and proposes ways to break related lock-ins in the context of sustainability transition research. To be able to change farming practices and design policies to promote the changes, it is essential to understand what actually needs to change. Do we need to change the ways farmers think, the ways that food markets operate, the requirements of plant varieties or the requirements related to protecting water quality? In a complex situation the needed change emerges from the intertwinement of many different issues, which simultaneously work to create the locked-in situation. A focus on people and their practices provides a good start…
Transition in the Finnish forest-based sector: Company perspectives on the bioeconomy, circular economy and sustainability
2019
The forest-based sector is affected by many profound structural changes and the increasing complexity of the business environment due to, for example, the mature markets of many core products and the aims for bio and circular economies and more sustainable societies. In response to the changing business environment, forest-based sector firms need to restructure their business models and develop new products and services. From the Finnish perspective, new forest-based businesses are crucial in the transition to successful and sustainable bio and circular economies. Views on the concepts of bioeconomy, circular economy and sustainability vary according to which parties are involved. Developin…
“Your ride has arrived” – Exploring the nexus between subjective well-being, socio-cultural beliefs, COVID-19, and the sharing economy
2021
This study aimed to identify and explain different facets of the sharing economy and to differentiate between micro- and macro-mobility services. We also aimed to examine the correlation between the sharing economy and subjective well-being, cultural beliefs, and COVID-19. An exploratory research technique with face-to-face semi-structured interviews was used to collect data from a sample of 22 rideshare app users in a developing country between January and May 2020 and in July 2020. The data were analyzed using the NVivo 12 application. The major findings suggest that, considering their scope and use, sharing economy technology and services can be divided into four major domains: (1) hospi…
Early health, risk aversion and stock market participation
2021
To examine the relationship between early health status and financial decisions in adulthood, we link information on birth weight in 1966 from the Northern Finland Birth Cohort to data from the Finnish Central Securities Depository over the period of 1995–2010. We find that persons predisposed to poor health status in early childhood (indicated by low birth weight) avoid participating in the stock market in adulthood, with a 10% increase in birth weight associated with a 1.9% increase in probability of participation. The link between birth weight and stock market participation is partially channeled by poor early health status being associated with higher risk aversion. Early health status …
The Continued Innovation-Decision Process : A Case Study of Continued Adoption of Robotic Process Automation
2022
Robotic Process Automation (RPA) originally entered the field of information systems as one of those disruptive innovations that will, among other automation solutions, have a profound effect on job descriptions and work itself in near future. One of the sectors that will be revolutionized – and are in fact already changing – are financial and human resource (HR) services, such as accounting, billing, and payroll services. According to statistics, Finnish companies operating on the administrative and support services sector make little use of service robots. Companies that have initially adopted the technology do not necessary reach its full potential. We explore what factors create challen…
