Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Electronic records management in Small and Medium Enterprises is a relatively new research area. It is difficult to find much on the SME and electronic record management in academic databases. In public organizations and in large enterprises the management of electronic records is now acknowledged as important for business support. Efficient records management is e.g. necessary for fulfilling requirements found in various legislation such as e.g. the Sarbanes-Oxley Act (SOX). The requirements for documentation in the ISO 9000, and the ISO 14000 series can be fulfilled if standards for records management are used.This paper aims to contribute further knowledge on the quality of records management in SMEs. The following research question has guided this research: How well do SMEs meet minimum ISO 15489 requirements for records management?The research has been carried out within a EU funded research program, where 4 SMEs from both Sweden and Finland have been studied using a qualitative research approach. The data have been collected from four SMEs through interviews. The analytical lens used in this research has been the international standard for Information and Documentation - Record Management: ISO 15489.The results show that electronic records are managed in a rather ad-hoc manner and that management is very dependent upon individuals, many of whom have little, if any, expertise or training in this area and no access to expert advice. One of the identified business values of well-managed electronic records is that the SME gains the opportunity to manage and benefit from their explicit knowledge and experience.This research shows that there are major obstacles to overcome before SMEs are able to fully adopt best practice in electronic records management. Many of these hindrances have their roots in a lack of appropriate strategies for records appraisal and that the SMEs have not followed the steps recommended in the ISO 15489 standard.

The value of simplicity : image browsing techniques and tests
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Image browsing is involved in many different types of tasks, such as interacting with a desktop and file system, viewing digital photo albums, etc. Different techniques are available for different types of tasks, but results from image browsing tests have been varied.The work of this thesis includes a literature survey, describing the most common image browser features and mechanisms, and summarizing research on the topic. The survey is followed by two image browsing studies, comparing an iconic interface to a zoom-and-pan and a fisheye interface. One study was made on a regular 19" display, and the other one on a 50" display with a 3D mouse. Both studies showed that none of the zoom-and-pan and the fisheye interfaces were more efficient than the simple iconic interface. The iconic interface was also the one most preferred by users. The problem with conflicting research results in this field is addressed in a summary of layout and presentation factors. There are a number of things, besides just interaction style, that affects usability. A lot remains to be investigated, and the analysis presented in this thesis gives an idea of some things to consider for future research. The two final studies of this thesis were parts of an interface design proposal for an oil analysis interface. One experiment showed that for reading single graphs, multiple diagrams with only one line graph in each are more efficient than one single chart with several line graphs. The final study of this thesis is a comparison of two graph tables, one distortion-oriented, and one overview+detail version. A theoretical analysis showed that for certain task types the static overview+detail interface would be more efficient than the distortion-oriented one, which was confirmed by the statistical analysis of data from the experiment. Users preferred the static overview+detail interface, mainly because they did not like that the view changed.The common experience of this work is that simplicity is highly valuable in many aspects. A simple interaction technique, such as an iconic interface, is often more efficient and more appreciated by users, than more advanced techniques. Reading single line graphs is more efficiently done in single small diagrams than in one large common diagram. Simple static modes are by many users preferred to dynamic modes. And finally, simple usability tests with a minimized number of confounding variables could explain and reduce the problem with conflicting results. Hence, the main conclusion and message of this thesis goes for both interface design and testing: Keep it simple.

- We present an algorithm for controlling and scheduling multiple linear time-invariant processes on a shared bandwidth-limited communication network using adaptive sampling intervals. The controller is centralized and not only computes at every sampling instant the new control command for a process but also decides the time interval to wait until taking the next sample.The approach relies on model predictive control ideas, where the cost function penalizes the state and control effort as well as the time interval until the next sample is taken. The latter is introduced to generate an adaptive sampling scheme for the overall system such that the sampling time increases as the norm of the system state goes to zero. This paper presents a method for synthesizing such a predictive controller and gives explicit sufficient conditions for when it is stabilizing. Further explicit conditions are given that guarantee conflict free transmissions on the network. It is shown that the optimization problem may be solved offline and that the controller can be implemented as a lookup table of state feedback gains. The simulation studies which compare the proposed algorithm to periodic sampling illustrate potential performance gains.

Time for change: Can empowerment be a solution to meet the perils of modern day working life?

Tidskriftsartikel (refereegranskat)abstract
- Working life continues to undergo rapid change. This change creates greater demand and sophistication and causes employees to experience more pressure, professionally and personally. Thus, absences from work due to sickness and injuries increase. In Sweden, this problem has become serious. This article argues that psychological empowerment and individual control are two key factors that minimize the many perils faced by the modern worker and those seeking to return to the work force through the vocational rehabilitation process. The findings show that a shift in ideology is needed. Specifically, there must be a shift from scientific management and Weberian bureaucracy towards organizational structures, routines, and cultures that support and increase individual worker psychological empowerment and control.
