- In the area of governmental information for and services to citizens digitalization has certainly become a buzzword. Framed within the discourses on e-government or e-governance – or different mixtures of the two – various analyses have tried to point out, or even anticipate possible consequences of the appropriation of digital technologies, mainly the internet, in governmental services.On the one hand, these analyses have pointed out a great deal of opportunities connected to the incorporation of the internet into governmental information and services. Policy makers have been quick to point to the increased accessibility as a great opportunity for the citizens; in Sweden this vision of accessibility has even been referred to as ‘24:7-governmental agencies’. Academics, among others, have also suggested that the digitalization of information and services opens up new possibilities for citizen control of governments.On the other hand, a number of problems have also been identified. For instance, the digitalization of public registers holding personal information has been interpreted as a threat to the citizens’ integrity: Will digitalization bring a new surveillance society? The most frequently debated problem, however, at least within research, has been the fear of digital divides. Will the internet create digital cleavages between different groups of citizens?So far, however, neither the hopeful nor the dystopian analyses have made enough efforts to critically evaluate their claims. Such evaluations can start from different points of departure, and in this paper the starting point is the citizens as users of governmental information and services through the internet: What patterns of inclusion and exclusion emerge as a governmental agency digitalizes its information and services by making them increasingly internet based?The paper presents statistical data from a survey of 762 unemployed citizens using the Swedish Public Employment Service, a governmental agency that has come to rely specifically heavy on internet based information and service. The initial analysis of data reveals interesting differences between social groups in terms of both perception and use of the internet – in general – and the resources offered by SPES in particular. For instance, the users’ various degrees of education is a strong, determining factor when it comes to use of internet SPES’ services.The paper starts from a conceptual elaboration of various notions of e-government and e-governance. Thereafter, the survey data is described and elaborated on before moving into a discussion of the wider significance of the findings: What does data suggest in terms of patterns of inclusion in and exclusion from a society in which governmental agencies, to an increasing extent, use the internet for their information and services?

Impossibility results for the equational theory of timed CCS

- We study the equational theory of Timed CCS as proposed by Wang Yi in CONCUR'90. Common to Wang Yi's paper, we particularly focus on a class of linearly-ordered time domains exemplified by the positive real or rational numbers. We show that, even when the set of basic actions is a singleton, there are parallel Timed CCS processes that do not have any sequential equivalent and thus improve on the Gap Theorem for Timed CCS presented by Godskesen and Larsen in FSTTCS'92. Furthermore, we show that timed bisimilarity is not finitely based both for single-sorted and two-sorted presentations of Timed CCS. We further strengthen this result by showing that, unlike in some other process algebras, adding the untimed or the timed left-merge operator to the syntax and semantics of Timed CCS does not solve the axiomatizability problem.

- This paper presents a general technique for obtaining new results pertaining to the non-finite axiomatizability of behavioral semantics over process algebras from old ones. The proposed technique is based on a variation on the classic idea of reduction mappings. In this setting, such reductions are translations between languages that preserve sound (in)equations and (in)equational proofs over the source language, and reflect families of (in)equations responsible for the non-finite axiomatizability of the target language. The proposed technique is applied to obtain a number of new non-finite axiomatizability theorems in process algebra via reduction to Moller’s celebrated non-finite axiomatizability result for CCS. The limitations of the reduction technique are also studied.

Effects of a Nordic diet on cardiovascular and metabolic risk factors in hypercholesterolemic subjects: a randomized controlled study
- 2009
-
Konferensbidrag (refereegranskat)abstract
- Background: Apart from lipid-lowering drugs, dietary changes can also reduce plasma LDL-C concentrations. No studies have been conducted to investigate the clinical effects of a diet with traditional foods originating from the Nordic countries. Method: In a randomised, controlled parallel-group intervention study 88 mildly hypercholesterolemic men and women were randomized to either an ad libitum Nordic diet (ND) or a control diet (CD) for 6 weeks. All meals and foods were provided to the participants in the ND group. Primary outcome measure was LDL-cholesterol, and secondary outcomes were blood pressure, plasma insulin and glucose concentrations. The ND was a high-fibre diet rich in plant foods (fruit, berries, vegetables, root vegetables, whole grain cereals and legumes), vegetable fats (rapeseed oil and nuts) and fatty fish, low-fat milk products, but low in salt, added sugars, saturated fats and red meats. Result: 86 subjects completed the study. Distribution of carbohydrates, fat and protein (E%) in ND was 54, 27, 19, respectively. ND lowered plasma total cholesterol 0.98±0.75 mmol/l (-16%), LDL-C by 0.83±0.67 mmol/l (-21%), HDL-C 0.08±0.23 mmol/l (-5%), including reduced LDL/HDL ratio by -0.42±0.57 (-14%) (all p<0.01 versus controls). Insulin concentrations decreased by 0.51± 2.25 (-9%, p=0.01) and systolic blood pressure by 7±13 mmHg (-5%, P<0.01) compared to controls. Despite diets were eaten ad libitum, body weight decreased by 3.0 kg in the ND (P<0.001). No significant differences were found for diastolic blood pressure, triglycerides or plasma glucose. Conclusion: A Nordic diet improves blood lipid profile, and insulin sensitivity as well as lowering blood pressure to a clinically significant extent in hypercholesterolemic subjects.

- Application specific architectures are highly desirable in embedded parallel computing systems at the same time as designers strive for using one embedded parallel computing platform for several applications. If this can be achieved, the cost can be decreased in comparison to using several different embedded parallel computing systems. This paper presents a novel approach of running several high-performance applications concurrently on one single parallel computing system. By using a reconfigurable backplane interconnection system, the applications can be run efficiently with high network flexibility since the interconnect network can be adapted to fit the application that is being processed for the moment. More precisely, this paper investigates how the space time adaptive processing (STAP) radar algorithm and the stripmap synthetic aperture radar (SAR) algorithm can be mapped on a multi-cluster processing system with a reconfigurable optical interconnection system realized by a micro-optical-electrical mechanical system (MOEMS) crossbars. The paper describes the reconfigurable platform, the two algorithms and how they individually can be mapped on the targeted multiprocessor system. It is also described how these two applications can be mapped simultaneously on the optical reconfigurable platform. Implications and requirements on communication bandwidth and processor performance in different critical points of the two applications are presented. The results of the analysis show that an implementation is feasible with today's MOEMS technology, and that the two applications can be successfully run in a time-sharing scheme, both at the processing side and at the access for interconnection bandwidth.

Konferensbidrag (populärvet., debatt m.m.)abstract
- Malaysian manufacturing firms are interested in New Product Development (NPD) methods, due to the fact that they are competitive tools for survival. The purpose of the present study is to investigate NPD practices in Malaysia, in particular the outsourcing of NPD and the organizing of NPD. We achieved our objectives by conducting a survey of 72 companies in the automotive, chemical, and electrical industries and analyzing the results. Managers involved in NPD will benefit from the findings presented in this paper. The results indicate that the NPD practices used in Malaysian firms focus more on production cost and manufacturability, whereas the need for increased knowledge receives lower priority.
