Resilience Planning, a Facilitated Modelling Approach

2018

Resilience has emerged as a buzzword among researchers and practitioners. However, despite its popularity, there has been little progress in moving it from an elaborate metaphor describing an idyllic state of the system to a tool for planning and managing adaptation. While case study research is rich with examples of systems that have proven to be resilient or are striving to develop resilience, there is no defined approach that operationalises concepts described in the literature into the planning process. This paper helps close this gap by illustrating how facilitated modelling can be used for resilience planning in socio-ecological systems. The paper summarizes our experience using facil…

Towards Measuring the Agility of Software Business

2018

Agile development methods have been employed across the software industry. However, it is not always clear if the used methods actually help the software firms in being more agile and if agility has a positive influence in the software firm performance. Studying these questions may turn out impossible since good measurements for assessing the overall agility of software firms do not yet exist. A need is therefore detected to measure the differences in agility between firms and finding the means to evaluate the differences in agility in reliable manner. This article examines how to measure the agility of a software firm and reports initial steps in the process of developing measurement instr…

Practices and Infrastructures for Machine Learning Systems : An Interview Study in Finnish Organizations

2022

Using interviews, we investigated the practices and toolchains for machine learning (ML)-enabled systems from 16 organizations across various domains in Finland. We observed some well-established artificial intelligence engineering approaches, but practices and tools are still needed for the testing and monitoring of ML-enabled systems. Peer reviewed

Information system implementation model and observations - Case health care, social services and other service processes in smaller municipalities

2012

Public sector in Finland is under heavy pressure to get more efficient and customer oriented. Information systems and their development is one possibility to improve municipalities’ own processes and their service offering to the inhabitants. In this study we investigated what is the status of Information Systems in municipal governance and architecture management. The situation with systems landscape and architecture is, based on our findings, very scattered and municipals do not make their decisions, for example outsourcing decisions, in a systematic way. Based on those findings, especially in small municipalities, we created a model, which municipal ICT responsible professionals can foll…

Feedback and Communication in Active Hydrogel Spheres with pH Fronts: Facile Approaches to Grow Soft Hydrogel Structures

2021

Abstract Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life‐like materials, we compartmentalized urea‐urease and more complex urea‐urease/ester‐esterase pH‐feedback reaction networks into hydrogel spheres and investigate how fuel‐driven pH fronts can be sent out from these spheres and regulated by internal reaction networks. Membrane characteristics are installed by covering urease spheres with responsive hydrogel shells. We then encapsulate the two networks (urea‐urease and ester‐esterase) separately into different hydrogel spheres to devise communication, pattern formation and attracti…

Value Co-Destruction: A Conceptual Review and Future Research Agenda

2023

The service-dominant (S-D) logic lens for understanding value co-creation and customers’ interactive roles in the service exchange has emerged as a focal theme of interest among service academics and practitioners. While recent investigations have also focused on the process of value co-destruction—that is, how potential negative outcomes occur—the concept and its distinction from value co-creation remain unclear. This conceptual review synthesizes the concept of value co-destruction and proposes a framework consisting of two interrelated dimensions—actor–actor interaction and individual actor —and their components at three temporal points of the service encounter. We distinguish value co-…

Evolutionary Dynamics of Pathoadaptation Revealed by Three Independent Acquisitions of the VirB/D4 Type IV Secretion System in Bartonella

2017

The α-proteobacterial genus Bartonella comprises a group of ubiquitous mammalian pathogens that are studied as a model for the evolution of bacterial pathogenesis. Vast abundance of two particular phylogenetic lineages of Bartonella had been linked to enhanced host adaptability enabled by lineage-specific acquisition of a VirB/D4 type IV secretion system (T4SS) and parallel evolution of complex effector repertoires. However, the limited availability of genome sequences from one of those lineages as well as other, remote branches of Bartonella has so far hampered comprehensive understanding of how the VirB/D4 T4SS and its effectors called Beps have shaped Bartonella evolution. Here, we repor…

Treatment of mice with rIL-4 or rIL-13 induces a Th2 response and RELM-β overexpression in response to primary Echinostoma caproni and infection but not resistance to infection. (A) expression of cytokine mRNA in the intestinal tissue of rIL-4-treated or rIL-13-treated mice at 2 weeks post-primary infection with E. caproni; (B) expression of RELM-β mRNA in the intestinal tissue (F) of naïve mice, non-infected rIL-4- or rIL-13-treated mice and infected rIL-4- or rIL-13-treated mice at 2 weeks post-primary infection. The relative quantities (RQ) of cytokine genes are shown after normalization with β-actin and standardization of the relative amount against day 0 sam…
