- Following the completion in May 2011 of the shutdown for the installation of the beryllium wall and the tungsten divertor, the first set of JET campaigns have addressed the investigation of the retention properties and the development of operational scenarios with the new plasma-facing materials. The large reduction in the carbon content (more than a factor ten) led to a much lower Z(eff) (1.2-1.4) during L- and H-mode plasmas, and radiation during the burn-through phase of the plasma initiation with the consequence that breakdown failures are almost absent. Gas balance experiments have shown that the fuel retention rate with the new wall is substantially reduced with respect to the C wall. The re-establishment of the baseline H-mode and hybrid scenarios compatible with the new wall has required an optimization of the control of metallic impurity sources and heat loads. Stable type-I ELMy H-mode regimes with H-98,H-y2 close to 1 and beta(N) similar to 1.6 have been achieved using gas injection. ELM frequency is a key factor for the control of the metallic impurity accumulation. Pedestal temperatures tend to be lower with the new wall, leading to reduced confinement, but nitrogen seeding restores high pedestal temperatures and confinement. Compared with the carbon wall, major disruptions with the new wall show a lower radiated power and a slower current quench. The higher heat loads on Be wall plasma-facing components due to lower radiation made the routine use of massive gas injection for disruption mitigation essential.

European industrial transformation : the effects of digitization
- 2011
-
Ingår i: Proceedings of the 13th Swedish network for European studies in economics and business conference. ; , s. 1-41

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper reviews the impact of digitization and information technology over several decades in four industries representing a cross-section of the entire economy. It is based on in-depth studies of the raw material production, manufacturing, retailing, and public service sectors in Sweden. The focus is on the content of industrial transformation in the form of new and improved products, improved processes, changed organizational structures, and redefined industry boundaries. Some of these changes are measurable in terms of their economic impact, but most are not. We find that digitization has been a gradual and iterative process involving interrelated technological and organizational changes. This confirms the findings in previous studies that Sweden is the leading country in Europe in adopting IT and may help to explain Sweden’s successful economic performance over the last decade or so.

Differentiation of IT-strategy in health care: beyond IT alignment
- 2010
-
Ingår i: Uppsala Public Management seminar.
-
Konferensbidrag (refereegranskat)abstract
- Information systems are playing a key role in the public management of health care as they have the potential to improve quality, efficiency, and patient care. Researchers as well as practitioners recurrently contend that a health care organization’s IS strategy should be aligned with the organization’s objectives and strategy, a notion commonly known as IT-alignment. This paper argues that such studies often views IT as one single and monolithic technological artefact and disregards that there are many types of IT depending of context, purpose and functionality. This perspective was also evident in the empirical data in our study. Therefore, this paper tries to develop a conceptualisation of different kinds of IT in health care that can used as a “sensitizing device” during corporate discussions of IT-investments. The findings are based on a longitudinal study of six health care organizations in the Stockholm metropolitan area. The empirical data collection was conducted during the years 2005-2010 through interviews, focus groups, observations, and archival data. The theoretical contribution is that this paper provides a new perspective beyond the IT alignment perspective in health care. The empirical contribution is constituted by showing how hospitals can re-think their approach to their IT-strategy and in doing so improve its service quality, efficiency, and patient care.

- Abstract: Enterprise resource planning (ERP) systems implementation success factors have been widely researched, however, few have investigated ERP post-implementation success in organizational contexts. The paucity of research Into ERP system success evaluations partly motivates this research To that end, the objective of this study is twofold First, it primarily investigates the relationships among six constructs or dimensions in a respecified ERP system success measurement model, which was developed from prior relevant frameworks. Second, this research adds to the body of knowledge in the information system (IS) success evaluation domain, especially with its focus on ERP packages The extended ERP system success model was tested using data collected in a cross-sectional field survey of 109 firms in two European countries Structural equation modeling (SEM) was used to test six relevant hypotheses. The SEM results showed that five out of the six hypotheses have significant, positive associations. Namely, the constructs of System Quality, Service Quality, Individual Impact, Workgroup Impact, and Organizational Impact have strong relevance in ERP success conceptualization, whereas Information Quality does not, at least, in the context of our data. The pertinence of the study's findings for IS success evaluation as well as its implications for practice and research are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Background: Information technology (IT) plays a key role in public health care management because it could improve quality, efficiency, and patient care. Researchers and practitioners repeatedly contend that a health care organization's information systems strategy should be aligned with its objectives and strategies, a notion commonly known as IT alignment.Purpose: Actor-related IT alignment issues in health care institutions were explored in this study. More specifically, it explores the possibility of moving beyond the current IT alignment perspective and, in so doing, explores whether IT alignment-as currently conceptualized in the dominant body of research-is sufficient for attaining improved quality, efficiency, and patient care in health care organizations.Methods: The findings are based on a qualitative and longitudinal study of six health care organizations in the Stockholm metropolitan area. The empirical data were gathered over the 2005-2011 period from interviews, a focus group, observations, and archival material.Findings: The data suggest recurrent misalignments between IT strategy and organizational strategy and operations due to the failure to deconstruct the IT artifact and to the existence of various levels of IT maturity.Conclusions: A more complex picture of IT alignment in health care that goes beyond the current perspective is being offered by this study. It argues that the previously common way of handling IT as a single artifact and applying one IT strategy to the entire organizational system is obsolete.Managerial Implications: The article suggests that considerable benefits can be gained by assessing IT maturity and its impact on IT alignment. The article also shows that there are different kinds of IT in medical care that requires diverse decisions, investments, prioritizations, and implementation approaches.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- n this final chapter we discuss the book’s principal conclusions based on its empirical, theoretical and practical contributions. This is done in six subsections, each focusing on a specific issue. In the first section, we discuss the significance of strategic congruence and integrated control; in the second, the importance of the environment for internal changes and competitive advantage, as well as performance. We devote the third section to the control mix, the fourth to the role of IT systems in creating strategic congruence and integrated control. Then, in the fifth section, we treat questions of methodology before going on to the sixth subsection, where we conclude with a discussion on central issues where further research is needed. We would advise the reader that as the sections are clearly interlinked, certain discussions recur in several places in the chapter.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- One of the few books to integrate the three areas of strategy, management control and competitive advantage in a multilevel settingPresents a theoretical framework for analyzing successfully combinations of strategy and control systemsContains detailed case descriptions, which are very rare in this subject areaHow should firms’ control systems be designed and used to formulate and implement strategies that will contribute to competitive advantage and sustained high performance? This book offers some thought-provoking suggestions. It contains empirical studies of such diverse manufacturing enterprises as Atlas Copco, Electrolux, Saab, Scania, SCA Packing and Volvo, as well as an insurance company and two chamber orchestras. All firms and organizations presented offer interesting and exciting insights, each in a specific way and each with a fascinating history.The book presents research on the relationship between strategy, control and competitive advantage over extended periods and at several strategic levels, while also taking into account the existence of multiple control systems in a single firm or other organization. Readers are offered an in-depth look into how changes in the environment lead to adjustments in strategies and control systems. It is shown, in addition, how difficult and challenging it can be to implement these changes, and why such efforts are not always successful. But perhaps most importantly, the book conveys an in-depth understanding of how strategies and control systems affect competitive advantage and performance.In both its coverage and focus, the book is unique. Not only does it provide valuable contributions to the research field of strategy and management control; it also represents a substantial commitment in terms of resources and involvement over an extended period.The book is highly recommended to researchers, practitioners, graduate students and all others interested in this area.
