abstract: The coordination of developing various complex and large-scale projects using computers has been well established and is the so-called computer-supported cooperative work (CSCW). Collaborative software development consists of a group of teams working together to achieve a common goal for developing a high-quality, complex, and large-scale software system efficiently, and it requires common processes and communication channels among these teams. The common processes for coordination among software development teams can be handled by similar principles in CSCW. The development of complex and large-scale software becomes complicated due to the involvement of many software development teams. The development of such a software system can be largely improved by effective collaboration among the participating software development teams at both software components and system levels. The efficiency of developing software components depends on trusted coordination among the participating teams for sharing, processing, and managing information on various participating teams, which are often operating in a distributed environment. Participating teams may belong to the same organization or different organizations. Existing approaches to coordination in collaborative software development are based on using a centralized repository to store, process, and retrieve information on participating software development teams during the development. These approaches use a centralized authority, have a single point of failure, and restricted rights to own data and software. In this thesis, the generation of trusted coordination in collaborative software development using blockchain is studied, and an approach to achieving trusted cooperation for collaborative software development using blockchain is presented. The smart contracts are created in the blockchain to encode software specifications and acceptance criteria for the software results generated by participating teams. The blockchain used in the approach is a private blockchain because a private blockchain has the characteristics of providing non-repudiation, privacy, and integrity, which are required in trusted coordination of collaborative software development. This approach is implemented using Hyperledger, an open-source private blockchain. An example to illustrate the approach is also given. / Dissertation/Thesis / Masters Thesis Software Engineering 2020

Health Informatics has enlightened by the recent development in the internet of medical things 4.0. Healthcare services have seen greater acceptance of Information and Communications Technology (ICT) in recent years; in light of the increasing volume of patient data, the traditional way of storing data in physical files has eventually moved to a digital alternative such as Electronic Health Record (EHR). However, the conventional healthcare data systems are plagued with a single point of failure, security issues, mutable logging, and inefficient methods to retrieve healthcare records. Solid (Social Linked Data) has been developed as a decentralized technology to alter digital data sharing and ownership for its users radically. However, Solid alone cannot address all the security issues posed to data exchange and storage. This work combines two decentralized technologies, Solid ecosystem and Blockchain technology, to tackle potential security issues using Solidity-based Smart Contracts, thereby providing a secure patient centric design. This research evaluates a model solution for secure storage, emphasizing secure auditing of accessing the data stored. The architecture will also come with algorithms that will provide developers with logical instructions to implement the artefact.

Bakgrund: Sedan 1980-talet har en uppsättning organisatoriska idéer och teorier lånade från näringslivet under namnet New Public Management tagit sig in i den offentliga sektorn och sjukvården. I takt med att medvetenheten om dessa idéer och teorier ökat hos allmänheten har en levande debatt om New Public Management inom sjukvården tagit fart. Från politiskt håll har nu en önskan om att utveckla nya styrmodeller för offentlig sektor bortom New Public Management lagts fram. Därför är det av intresse att studera New Public Management-diskursen kring svensk sjukvård. Syfte: Denna studie avser studera den rådande New Public Management-diskursen kring svensk sjukvård. Utifrån ett kritiskt analytiskt perspektiv är syftet med studien också att undersöka hur denna diskurs kan kopplas till de strukturella relationer som manifesteras av språket. Metod: Kritisk diskursanalys Teorier: New Public Management, Revisions- och mätbarhet, Kvalitetsbegreppet, Diskursanalys, Kritisk diskursanalys Empiri: Sekundärdata bestående av debattartiklar om svensk sjukvård. Slutsats: Denna studie har identifierat en strukturell maktrelation i den diskursiva praktiken som manifesteras i språket. / Background: Since the 1980s, a collection of organizational ideas and theories borrowed from the private sector and under the name of New Public Management have entered the public sector and healthcare. As the public awareness of these ideas and theories has increased, a vivid debate about New Public Management within the healthcare has gained momentum. Politically, a wish for a development of new models of management beyond New Public Management in the public sector have been introduced. Thus, it is of interest to study the discourse of New Public Management surrounding Swedish healthcare. Objective: This thesis aims to study the current discourse of New Public Management surrounding Swedish healthcare. By using a critical analytical perspective the objective of the thesis is also to study how this discourse can be linked to the structural relations that manifest themselves through language. Method: Critical discourse analysis Theories: New Public Management, Auditability, Concept of quality, Discourse analysis, Critical discourse analysis Empiric: Secondary data consisting of debate articles about Swedish healthcare Conclusion: This thesis have identified a structural relation of power in the discoursive dimension which manifest itself through language.
