Functional and Structural Roles of Data in Service Ecosystems

2023

Data play an increasingly important role in today’s service ecosystems, where actors integrate resources to create value at different levels of aggregation (micro, meso, macro). To advance our understanding of the role of data in such contemporary data-rich service ecosystems, we draw on the service-dominant (S-D) logic and data ecosystem literature. Extending the current understanding of data in the literature, we demonstrate how data and data ecosystems have become intertwined with service ecosystems and how data as a meta-resource connects actors, enhances systemic visibility, and drives innovation in these ecosystems. peerReviewed

Creating Shared Value: Exploration in an Entrepreneurial Ecosystem

2022

The effects of companies on society and the practices of Corporate Social Responsibility have been the source of interest for many research studies. Questions concerning the traditional model resulted in Porter and Kramer developing the concept of Creating Shared Value, an approach where companies consider the value of society and the environment in their business models, creating value for all stakeholders. We take the issue of shared value creation in an entrepreneurial ecosystem to determine how clustered companies understand and create shared value, identifying its antecedents and consequences. Using a single case study, we were able to identify that the entrepreneurial ecosystem become…

From Agile Software Development to Mercury Business

2014

The rapid downfall of the Nokia software ecosystem has radically altered the landscape of software industry in Finland in recent years. There has been a shift from largely corporate driven way of working, which is often dominant in large companies, to more agile practices, and in general software organizations are seeking new, leaner ways of composing, delivering, and using software also inside already established companies. To accelerate this transformation in large scale, a collaborative research program has been created, called Need for Speed (N4S). In this paper, we give an insight to the joint goals and concrete actions of the program and discuss the motivations of individual companies…

Denitrifying microbial communities along a boreal stream with varying land-use

2019

Streams have an important role in regulating nitrogen (N) transportation from terrestrial ecosystems to downstream waters. Here, we examined how catchment land-use affects potential denitrification rates and the function and composition of denitrifier communities in boreal stream sediments, using stable isotope incubations and qPCR and 454-pyrosequencing targeted on nirS, nirK and nosZ genes. Although land-use influenced the water chemistry as higher nitrite + nitrate (NO x − ) concentration at the agriculture-affected sampling point, sediment organic matter content was found to be the key factor in regulating potential denitrification rates. However, the abundance as well as the diversity …

Emissions of atmospherically reactive gases nitrous acid and nitric oxide from Arctic permafrost peatlands

2022

Soils are important sources of nitric oxide (NO) and nitrous acid (HONO) in the atmosphere. These nitrogen (N)-containing gases play a crucial role in atmospheric chemistry and climate at different scales because of reactions modulated by NO and hydroxyl radicals (OH), which are formed via HONO photolysis. Northern permafrost soils have so far remained unexplored for HONO and NO emissions despite their high N stocks, capacity to emit nitrous oxide (N2O), and enhancing mineral N turnover due to warming and permafrost thawing. Here, we report the first HONO and NO emissions from high-latitude soils based on measurements of permafrost-affected subarctic peatlands. We show large HONO (0.1–2.4 µ…

Consistency of Targeted Metatranscriptomics and Morphological Characterization of Phytoplankton Communities

2020

The composition of phytoplankton community is the basis for environmental monitoring and assessment of the ecological status of aquatic ecosystems. Community composition studies of phytoplankton have been based on time-consuming and expertise-demanding light microscopy analyses. Molecular methods have the potential to replace microscopy, but the high copy number variation of ribosomal genes and the lack of universal primers for simultaneous amplification of prokaryotic and eukaryotic genes complicate data interpretation. In this study, we used our previously developed directional primer-independent high-throughput sequencing (HTS) approach to analyze 16S and 18S rRNA community structures. C…

Otolith chemical composition suggests local populations of Antarctic silverfish Pleuragramma antarctica (Boulenger, 1902) around Antarctica are expos…

2021

The Antarctic silverfish Pleuragramma antarctica is a key species in the Southern Ocean ecosystem, and it is potentially threatened by the climate change affecting Antarctic ecosystems. Assessing the possible exposure to similar or different environmental conditions at early life stages and gathering information about connectivity or segregation between local populations of P. antarctica can be key for planning sound management strategies for this species. By using Laser Ablation Inductively Coupled Plasma Mass Spectrometry, we characterized the otolith chemical composition of 163 adult Antarctic silverfish collected from three areas located thousands of kilometers apart from each other: Ca…
