- Open hardware and open source software platforms bring benefits to both implementers and users in the form of system adaptability and maintainability, and through the avoidance of lock-in, for example. Development of the \riscv\ Instruction Set Architecture and processors during the last ten years has made the implementation of a desktop computer using open hardware, including open processors, and open source software an approaching possibility. We use the SiFive Unmatched development board and Ubuntu Linux, and the recorded experiences of system builders using the Unmatched board to explore the extent to which it is possible to create an open desktop computer. The work identifies current limitations to implementing an open computer system, which lie mainly at the interface between the operating system and hardware components. Potential solutions to the challenges uncovered are proposed, including greater consideration of openness during the early stages of product design. A further contribution is made by an account of the synergies arising from open collaboration in a private-collective innovation process.

- Software reference implementations of ICT standards have an important role for verifying that a standard is implementable, supporting interoperability testing among other implementations, and providing feedback to the standard development process. Providing reference implementations and widely used implementations of a standard as Open Source Software also promotes wide deployment in software systems, avoidance of different lock-in effects, interoperability, and longevity of systems and associated digital assets. In this paper results are reported on the availability of reference implementations and widely deployed implementations provided as Open Source Software for standards issued by different standards setting organisations. Specifically, findings draw from observations and analyses related to software implementations for identified standards issued by ETSI, IEC, IEEE, IETF, ISO, ITU-T, OASIS, and W3C.

On engagement with ICT standards and their implementations in open source software projects : the case of WebRTC

- Real-time communication (RTC) technologies for the web provide opportunities for individuals and organisations to work and collaborate remotely, and the need for such technologies has recently increased. Use of RTC technologies and tools for the web involves a number of challenges concerning data privacy and lock-in effects, such as dependency to specific suppliers and proprietary technologies. Use of open standards for RTC and open source software (OSS) implementing such standards can create conditions for avoiding issues related to data privacy and lock-in, and thereby provides opportunities for long-term sustainable solutions. The paper characterises how engagement with standardisation of WebRTC in the context of IETF and W3C is related to engagement with the WebRTC OSS project.

- Web analytics technologies provide opportunities for organisations to obtain information about users visiting their websites in order to understand and optimise web usage. Use of such technologies often leads to issues related to data privacy and potential lock-in to specific suppliers and proprietary technologies. Use of open source software (OSS) for web analytics can create conditions for avoiding issues related to data privacy and lock-in, and thereby provides opportunities for a long-term sustainable solution for organisations both in the public and private sectors. This paper characterises use of and engagement with OSS projects for web analytics. Specifically, we contribute a characterisation of use of OSS licensed web analytics technologies in Swedish government authorities, and a characterisation of organisational engagement with the Matomo OSS project for web analytics.

Enabling OSS usage through procurement projects : How can lock-in effects be avoided?

- Formulation of mandatory requirements in procurement projects has significant influence on opportunities for development and deployment of Open Source Software (OSS). The paper contributes insights on a widespread practice amongst public procurement projects which causes problematic lock-in effects and thereby inhibits opportunities for use of OSS solutions. Through a systematic investigation of 30 randomly selected procurement projects in the software domain the paper highlights illustrative examples of mandatory requirements which cause lock-in and presents five recommendations for how requirements instead should be formulated in order to avoid causing lock-in. Findings show significant lock-in caused by current procurement practices with a stark preference for proprietary software and SaaS solutions amongst procuring organisations.

Half a step behind – bulk disclosure of confidential data in third-party GenAI solutions under the Swedish Public Access to Information and Secrecy Act

Tidskriftsartikel (refereegranskat)abstract
- Technological progress poses unique challenges for the public sector. New technology should be adopted, but it must always be done within the framework of good administration. It follows laws governing public administration must be continuously adapted. Sweden recently amended its secrecy legislation to facilitate the use of third-party cloud solutions by public authorities. When the amendment was enacted, most public sector organisations had already been using external cloud solutions for a long time. Today, there is as much pressure on authorities to implement AI technology as there ever was to move administration into the cloud. This paper uses traditional legal methodology to investigate if the Swedish secrecy legislation adequately enables the use of cloud-based GenAI solutions. Findings indicate that the recent amendment is likely insufficient and that there are significant practical hurdles for the application of the law, particularly with services from global cloud providers. The paper contributes to the understanding of Swedish law, and of the difficulties that can occur anywhere when policy makers and legislators do not move in tandem.

Chemogenetic modulation of cholinergic interneurons reveals their regulating role on the direct and indirect output pathways from the striatum
- 2018

Tidskriftsartikel (refereegranskat)abstract
- The intricate balance between dopaminergic and cholinergic neurotransmission in the striatum has been thoroughly difficult to characterize. It was initially described as a seesaw with a competing function of dopamine versus acetylcholine. Recent technical advances however, have brought this view into question suggesting that the two systems work rather in concert with the cholinergic interneurons (ChIs) driving dopamine release. In this study, we have utilized two transgenic Cre-driver rat lines, a choline acetyl transferase ChAT-Cre transgenic rat and a novel double-transgenic tyrosine hydroxylase TH-Cre/ChAT-Cre rat to further elucidate the role of striatal ChIs in normal motor function and in Parkinson's disease. Here we show that selective and reversible activation of ChIs using chemogenetic (DREADD) receptors increases locomotor function in intact rats and potentiate the therapeutic effect of L-DOPA in the rats with lesions of the nigral dopamine system. However, the potentiation of the L-DOPA effect is accompanied by an aggravation of L-DOPA induced dyskinesias (LIDs). These LIDs appear to be driven primarily through the indirect striato-pallidal pathway since the same effect can be induced by the D2 agonist Quinpirole. Taken together, the results highlight the intricate regulation of balance between the two output pathways from the striatum orchestrated by the ChIs.
